The 9 Most Comfortable Hoodies

Описание: The 9 Most Comfortable Hoodies Whether you want to layer up for winter or enjoy a cool summer night, hoodies are a comfy and convenient staple to have in your wardrobe. Warm, cozy, and suitable for almost any outfit, the Whether you want to layer up for winter or enjoy a cool summer night, hoodies are a comfy and convenient staple to have in your wardrobe. Warm, cozy, and suitable for almost any outfit, the most comfortable hoodies come in a number of different materials and styles. When searching for a hoodie, deciding what works best for you and your lifestyle will be important. Do you live in a cooler climate and want one that keeps you nice and toasty? Or do you prefer something more lightweight that can be worn all year round? Some of the best materials for hoodies include cotton, polyester, or a blend of the two. Cotton is breathable and soft, while polyester is durable and moisture-wicking. Fleece is a fabric that's extra insulating and can be made from natural cotton or synthetic materials. And having a little spandex in a sweatshirt will add stretch and flexibility. Next, you'll want to think about what style you feel most comfortable in. Full-zip designs are ideal for those who like to have the option of leaving their hoodie open or closed, while half-zips have a relaxed, stylish look. Pullover hoodies are great for those who want a little bit more warmth and want to layer it under a jacket. Hoodies can also vary in shape from oversized, fitted, to even cropped, like one of my picks below. You'll also want to consider other smaller details, like thumbholes, kangaroo pockets, and drawstrings. From a micro-fleece hoodie that feels just like a soft throw blanket to a colorful tie-dye option, read on to find the best hoodie for you.What's great about it: What's great about it: If you're looking for something that's lightweight and loose-fitting, this oversized fuzzy hoodie is a great option. The sherpa-fleece fabric is made with a blend of polyester and spandex, so it's super soft and stretchy. Although it's lighter than some of the other options here, it still provides warmth and coziness. Designed with a front one-quarter zipper, it comes in more than a dozen colors and styles (just note that some styles don't have a hood). Reviewers recommend going a size down if you don't want it to fit too loosely. What fans say: "Super soft and I love it! I was pleasantly pleased with this as I’m apprehensive about buying clothing items on amazon. It came vacuumed sealed and is the same inside as it is outside, which I love that it’s not lined with something that’s not as warm! Buy this! No regrets!" What's great about it: What's great about it: With a durable construction and a cool, sporty look, this Champion cropped hoodie is a great spin on the classic wardrobe staple. Made with an anti-shrinking reverse weave, this hoodie will keep its shape and won't shrink over time. It's perfect for layering or you can wear it on its own with jeans or leggings. It has a loose fit and is available in both white (pictured above) and dark purple. What fans say: "I am a 5’2” female that’s weighs about 125 lbs. I ordered a small and it fits perfectly! It’s not too cropped and the sleeves are baggy and comfy, just as product is pictured. This is by far the most comfy cropped sweatshirt I have ever purchased, I recommend adding it to your wardrobe collection!" Difference Between Trousers and Pants Main Difference -Trousers vs PantsBoth Trousers and Pants refer to the same garment; they both refer to an outer garment covering the body from waist to ankles, with a separate part for each leg. The difference between them lies in usage. The main difference between trousers and pants is that the word trouser is commonly used in the UK whereas the word pants is commonly used in America. It is also important to note that in the UK, pants refer to undergarments. We are going to elaborate this difference between trousers and pants in this article. What are Trousers Trousers are an item of clothing worn on the lower part of the body and cover both legs separately (as opposed to cloth stretching across both legs as in skirts and dresses). For centuries, trousers have remained the standard lower-body clothing item for males; but, by the late 20th century, trousers had become a popular clothing item for females as well. Trousers are worn at the hips or waist; they are held up by their own fastenings, suspenders/braces or a belt. The word trouser is mainly used in British English; in American English, the term pant is used to refer to trousers. In America, trousers may specifically refer to a tailored garment consisting of a waistband, belt loops, and fly front. What are Pants In North America, pants is the general term used to refer to trousers. As explained above, trousers, in American English specifically refers to formal, tailored pants. However, in British English, the term pants is never used to refer to trousers. In England and most of the British English speaking countries, Pants refer to undergarments or underwear. In the US, what is worn under the pants is called underwear, underpants, or panties (panties specifically refer to women’s undergarments.) In the UK, pants are worn under the trousers. So this linguistic blend can result in awkward and embarrassing situations if you are talking with a British or American. If you say ‘nice pants’ to an American, he would in return, thank you for the compliment. But if you say the same for a British, it’d create an awkward situation as you are referring to his undergarments. Nevertheless, in some countries like Australia, pants and trousers are used synonymously. These two are not the only terms that refer to clothes worn to the lower part of the body in men’s wardrobe. There are other terms like slacks, jeans, khakis, chinos, Corduroys that are different varieties of pants/trousers. How To Wear A Polo Shirt The Polo shirt is a simple but timeless piece of clothing. As a classier alternative to the traditional T-shirt, you can easily dress this up or down, just by adding key pieces to complement it. With its distinctive collar, buttons, and breathable fabric, it’s an item you can wear to any occasion. Whether the temperature rises or there is a drop in mercury, here are the best ways to wear a polo shirt. Long Sleeve Polo Shirt Although polo shirts are typically seen in the warmer months, it doesn’t mean they’re exclusive to summer. Long sleeve polo shirts look fantastic when the temperature drops and they can be styled in several ways. For a casual feel, combine it with a pair of chinos, sneakers, and a leather jacket – it’s a timeless combination that looks great on anyone. The polo is an excellent clothing choice for those days where you don’t know what to wear. It’s easy to dress up or down and works in every season. Short-Sleeve Polo Shirt Show off your muscles and do it in style with a short sleeve polo shirt. The classic design behind this clothing is timeless and works well when combined with jeans, chinos, or even suit pants. Dress it up by donning a blazer with loafers, or keep it relaxed with sneakers and jeans. You can wear this stylish item in many ways, all you need is a bit of confidence, and you’re set. Undershirt Or Not? Why and When To Wear One Despite keeping to long-held traditions, the men’s fashion scene is constantly changing. It can be challenging to navigate these rules. Society doesn’t make it any easier on you because it’s constantly sliding closer and closer to casual wear. Today, truly formal events are far less common, and the definition of business casual varies. Sometimes it means you can wear short sleeves and khakis, which is a deviation from its former interpretation of simply skipping the blazer. Should I wear an Undershirt? Undershirts can be even more complicated. No one ever sees them, so it can be difficult to know when to wear them and when to skip them. Do they really affect your wardrobe that much? Should you wear an undershirt? What about with a white dress shirt? In short, yes (though you don't NEED one)! Undershirts weren’t made to be seen. They were made for your comfort. Wearing one can make your outfit feel much better on you and improve the fit of off the rack clothing. They don’t always go unseen, either. The way you wear it will determine whether you look great, or look like a total slob. T-Shirt Guide: What Sets Apart the Different Styles of T-Shirts in Artist Shops? Tees on tees on tees!

Guidelines for the Use of Antibiotic Drugs

Описание: Guidelines for the Use of Antibiotic Drugs Antibiotic drugs are commonly used in veterinary medicine to treat infectious diseases that are caused by bacteria and certain other microorganisms. There are many different classes of antibiotics available for use in animals, including penicillins, cephalosporins, cephamycins, aminoglycosides, quinolones, sulfonamides, tetracyclines, and macrolides. Some are effective against a wide range of organisms, while others are more closely targeted (for example, they may be effective against some bacteria but less effective against other bacteria). Thus, antibiotics are often referred to as broad-spectrum or narrow-spectrum drugs, respectively. Successful antibiotic treatment is based on 4 principles: 1) identifying the disease-causing agent and selecting the appropriate drug for treatment; 2) attaining effective concentrations of the drug at the site of infection for a sufficient period of time; 3) choosing a dose rate, frequency, and method of administering the dose that maximizes the likelihood of a cure, prevents relapse, and minimizes the risk of developing resistance while causing no harm to the animal; and 4) using specific and appropriate supportive treatment to improve the animal’s ability to overcome the infection and associated disease conditions. The emergence of bacteria that are resistant to currently available antibiotics within the animal or human population is of great concern. When resistance occurs, previously successful drugs can no longer be considered effective treatment, and new drugs must be developed. Resistance may develop in several different ways. However, when used properly (that is, the right antibiotic is used and it is given as prescribed for the appropriate amount of time), antibiotics are less likely to contribute to the selection of antibiotic-resistant organisms. When given a prescription from your veterinarian for your pet, make sure that it is given exactly as instructed and that the entire prescription is given. Not following dosage schedules or not giving all of the prescription can cause a relapse, a reinfection, or development of antibiotic-resistant organisms. Anthelmintic drugs Anthelmintics are drugs that are used to treat infections with parasitic worms. This includes both flat worms, e.g., flukes and tapeworms and round worms, i.e., nematodes. They are of huge importance for human tropical medicine and for veterinary medicine. The World Health Organization estimates that a staggering 2 billion people harbour parasitic worm infections. Parasitic worms also infect livestock and crops, affecting food production with a resultant economic impact. Also of importance is the infection of domestic pets. Indeed, the companion animal market is a major economic consideration for animal health companies undertaking drug discovery programmes. Despite the prevalence of parasitic worms, anthelmintic drug discovery is the poor relation of the pharmaceutical industry. The simple reason is that the nations which suffer most from these tropical diseases have little money to invest in drug discovery or therapy. It comes as no surprise therefore that the drugs available for human treatment were first developed as veterinary medicines. There is thus a pitifully small repertoire of chemotherapeutic agents available for treatment (see Table 1). In some respects, this situation has been exacerbated by the remarkable success of ivermectin over the last twenty years (Geary, 2005), which has decreased motivation for anthelmintic drug discovery programmes (Geary, Sangster and Thompson, 1999). This prompts concern, as anthelmintic resistance has been widely reported in livestock and it may also only be a matter of time before this phenomenon occurs in parasites of humans. Broad spectrum anthelmintics are effective against parasitic flat worms and nematodes. However, the majority of drugs are more limited in their action, e.g., praziquantel, a drug used in the treatment of schistosomiasis and thought to act by disrupting calcium homeostasis (Greenberg, 2005), has no activity against nematodes (see Table 1). For the purpose of this review we will focus on drugs used in human and veterinary medicine to treat parasitic nematode infection. How to Prepare for a Career in Veterinary Medicine Get Started in High School For a career in veterinary medicine, a high school student should develop a strong background in biology, chemistry, and physics. Courses in English, social science, and speech are also necessary since interpersonal and professional communications skills are important assets in veterinary medicine. Like most professions, veterinary medicine is very much a "people business." The most successful veterinarians are competent doctors as well as good communicators. Practical experience with animals is very important. Students should spend time volunteering for or working with veterinarians to develop an understanding of the profession. Non-veterinary animal experience may also be beneficial to students interested in veterinary medicine. Pre-Veterinary College Coursework No specific undergraduate program is preferred at Oregon State University, but students must complete a set of pre-veterinary requirements in chemistry, physics, mathematics, statistics, biology, genetics, physiology, and additional biological sciences. Courses in English, public speaking and humanities/social sciences are also required. Many students choose an animal science or biological science major because these bachelor's degree programs generally include most of the pre-veterinary requirements. Also, some of these programs allow students accepted into the DVM program after their junior year to apply credits earned in their first year of veterinary study toward completing a bachelor's degree. Students interested in veterinary medicine, should consult with a pre-veterinary medicine adviser when planning their undergraduate program. Oregon State University students may choose to contact one of the OSU pre-veterinary medicine advisers. Difference Between Mixture and Solution In chemistry, student tend to mix up or be confused about concepts like mixture and solution. These are basic concepts and there should be no excuse in mixing up the concepts. Besides students should master such concepts and it will help them avoid negative marking during exams. Thus, it is important to know the difference between mixture and solution. To help you understand the concepts, a mixture is a combination of usually two substances. Here, the substances are not combined chemically and their properties also remain the same. However, when we talk about a solution it is totally different. different. Solution is a type of mixture where substances are dissolved. Here you have to know about solute which is a substance that dissolves and solvent which dissolves the solutes to form a solution. Before diving into the differences, it is important to understand and remember that a solution is a type of mixture but a mixture may or may not be a solution. Now that we know a little about these two concepts, let’s look at some of the key differences between mixture and solution.In a mixture, substances are generally just mixed and are not completely dissolved.In a solution, substances are dissolved completely and they cannot be filtered out.Mixture comprises two or three compounds that aren’t fused chemically. They have no physical interactions. A solution contains two substances that are chemically mixed to form a new compound.The chemical properties of each substances are retained without change. Chemical properties usually changes.The amount of substances in a mixture can vary and amounts don’t have a fixed ratio.A solution usually has a fixed ratio or amount of substances.Mixtures can be classified primarily into two groups, namely homogeneous mixtures and heterogeneous mixtures.A solution is a type of a homogeneous mixture. These are some of the differences between mixture and solution. To know more about the mixtures and solutions and other chemistry topics you can keep visiting BYJU’s or download our app for interesting content and learning experience. Liquid refrigerant injectionLiquid refrigerant injection technique can be a very effective method for controlling subcooling and the compressor discharge temperature of a refrigeration system at high ambient temperatures. In this study, the effects of liquid refrigerant injection on the performance of a refrigeration system with an accumulator heat exchanger were investigated by varying the liquid injection rate at the conditions of constant expansion valve opening in the evaporator and constant total flow rate. During the tests, the ambient temperature was maintained at 43 °C. With the increase of the liquid injection rate, the subcooling at the inner heat exchanger outlet increased and the superheat at the accumulator outlet decreased. However, unacceptable results such as the increase of the compressor discharge pressure and decrease of the system performance were also observed depending on the control method applied. To obtain high system performance and reliability, optimum control methods for liquid injection in the accumulator heat exchanger are suggested. The liquid injection technique for the refrigeration system with an accumulator heat exchanger was found to be an effective method for controlling adequate subcooling and the compressor discharge temperature of the refrigeration system at high ambient temperatures.

Selecting shafts for linear bearings: two things you need to know

Описание: Selecting shafts for linear bearings: two things you need to know Both recirculating and plain linear bearings as well as track-roller wheel-based linear bearings can use a wide variety of shaft materials, depending on the application or environmental requirements. Shafts for recirculating linear bearings are typically made of bearing-grade carbon steel or stainless steel. Likewise, plain linear bearing systems can use carbon steel, stainless steel, or aluminum shafts. And for very harsh environments or special conditions, shafts can be plated or coated to withstand caustic or abrasive contaminants. When choosing which type of shaft to use in a linear bearing application, the two most important factors that contribute to bearing wear and life are the shaft’s surface finish and hardness. Surface finish Surface finish generally refers to the “roughness” of a surface, which is a measure of how much the surface topography varies from an ideal plane. Recirculating ball bearings operate best when paired with ground or polished shafts with a low roughness value. This is because a better surface finish actually increases the contact area between the shaft and the recirculating balls. A “rough” shaft surface, with a significant number of peaks and valleys, provides less contact area for the balls to ride on, whereas a smoother shaft surface provides more contact area for the load-carrying balls. Typical surface finish recommendations for shafts used with recirculating ball bearings are 6 to 10 microinch Ra. For plain linear bearings, however, a smoother shaft surface can actually lead to decreased life, due to the self-lubricating nature of most plain bearings. Plain bearings rely on features of shaft roughness — specifically, the “peaks” on the surface of the shaft — to transfer small amounts of the bearing material to the shaft. These dislodged bits of material fill in the valleys on the shaft surface and provide lubrication as the bearing travels back and forth. Without this lubrication, friction between the shaft and bearing will be higher, and the bearing’s PV rating will be reduced. This is also true for plain bearings made of bronze, which must be lubricated externally. A slight roughness of the shaft surface helps the shaft retain lubricant and prevent metal-to-metal contact. But as with recirculating bearing shafts, a surface that is too rough can also cause extensive wear on the bearing and lead to premature failure. The suggested range of surface roughness values depends on the bearing material, but as an example, composite bearing manufacturers generally recommend a shaft surface roughness of 8 to 16 microinch Ra. Shaft hardness Equally important to shaft surface finish is the shaft hardness. Sufficient shaft hardness is critical for recirculating linear bearings because point loading created by the balls can cause permanent deformation of the shaft. Because heavier loads place more stress on the surface of the shaft, they require higher hardness values than lighter loads. In fact, a shaft hardness factor (often denoted fH) is included in load and life calculations for recirculating ball bearings. The typical hardness recommendation for round shafts used with recirculating ball bearings is HRC 60, which corresponds to a shaft hardness factor, fH, of 1.0 (i.e. no increase in required load capacity or reduction in life). Hardness ratings below HRC 60 can significantly reduce the life of the bearing assembly. Note that stainless steel generally has a hardness value in the range of HRC 54, meaning assemblies that use stainless steel shafts will have a lower life expectancy, even if all other operating parameters are the same. Although shaft hardness is not as critical for plain linear bearings as it is for recirculating types, it does play a role in plain bearing wear. Because plain bearings don’t typically include seals or wipers, contaminants can become trapped between the bearing and shaft and, if the bearing material is soft, the contaminants can become embedded in the bearing. Likewise, if the shaft hardness is not sufficient, contaminants can also become embedded in the shaft. For example, Dupont demonstrates that bearings made of its Delrin? acetal resin experience less wear and better life when used with harder shafts. And for plain bearings made of bronze, the shaft material must be harder than the bearing material. Can We Chrome Plate Stainless Steel? The short answer is yes. Most common grades of Stainless Steel can be reliably Chrome Plated, this may however not be the most appropriate process depending on your application. For A Bright, Shiny Finish For decorative applications, it may be simpler to instead Electro-polish the item instead. During the elctro-polishing process the component is fitted with two electrodes which are connected to a power supply, this is then immersed into an electrolytic solution. This process removes surface impurities and promotes oxidation of the metal surface. This is a fantastic way to achieve a bright and shiny finish for your stainless steel components. For Protection Many commercial products such as car bumpers are chrome plated to increase their abrasion and scratch resistance. The process itself is often called nickel-chrome. This is because first a layer of nickel is added and then on top a thinner layer of chrome. Much of a products shine actually comes from the nickel ‘undercoat’. Nickel Plating may be one alternative if you are looking to give your component added protection. Nickel would certainly act as a protective barrier and is somewhat corrosive resistance, and quite often used to give products a shiny finish, but over time it will tarnish on its own and this is why Chrome is often used in conjunction to provide a hard and durable layer. What about Hard Chrome? ‘Hard Chrome’ differs from Bright Chrome in that it is an industrial process which is able to provide a thick, protective barrier for your parts. This will be able to provide a much higher level of wear and corrosive protection for your parts. Hard Chrome is certainly an option for Stainless Steel parts, but may not be suitable should your component/product need to meet REACH standards. So What Process? It very much depends on your application. Stainless Steel can be Chrome Plated, but if you are looking purely at making it brighter and more decorative then it may be better to simply polish it. Get in touch with Silchrome Plating together and we can help guide you as to the best plating or coating process. Silchrome are ISO 9001 and 14001 certified and based in Leeds, West Yorkshire. ID Honing The honing process is used to produce smooth surface finishes inside bores, or to hold precise tolerances on bore diameters. Honing produces the required surface finish or finished diameter by utilizing an abrasive stone, which turns while being moved in and out of the workpiece. Cutting fluids are used to provide smooth cutting action and to remove the cut material from the bore. MicroGroup has the capability of honing inside diameters of tubing and machined bore sizes from ?.064″ to ?1.00″ using its Sunnen honing machine. The process involves introducing a mandrel (tool) into an ID or bore to remove debris and/or to change an ID finish. A lubricant may be used. The material is abrasively removed by the shearing action of the grains contained in the honing tool. This allows inaccuracies of previous operations to be corrected. Roundness is generated by the tool rotation seeking the centerline of the I.D. or machined bore. Finishes of 8μin and better can be achieved depending on the material and size. The reciprocating motion of the tool generates straightness. Multiple grits and stages must be used in sizing if the rough diameter is not within certain limits of the finished requirements. MicroGroup also uses a process called “flexible-honing” or “ball-honing”. This process uses a resilient and flexible honing tool with a soft abrasive cutting action. Flexible-Hone tools are made with a heavy-duty twisted wire shaft that holds flexible nylon strands coated with abrasive globules or balls attached to the end of the nylon strands. These globules or balls conform to the shape of the surface to be honed to create a smooth, consistent finish in a cylinder bore or tube I.D. Flexible-Honing is also an excellent choice for cleaning the inside diameters of tubing. Four Types of Hydraulic Cylinders are Used in Many Applications It’s important to know which hydraulic cylinder is going to work best for your application. Each type of cylinder uses a different design and mechanisms to function. It’s also important to use cylinders that are designed by engineers and fluid power specialists. In this post, we will look at some of the different types of cylinders Best Metal Products has to offer. Single acting cylinders Single acting hydraulic cylinders are ideal for use in applications that have weight, gravity, or another assisting force which will move the cylinder in a single direction. Single acting hydraulic cylinders use hydraulic pressure to extend or retract the rod in one direction. Single acting cylinders often cost less than double acting cylinders and work well in a vast range of mobile and industrial applications. Double acting cylinders Double acting hydraulic cylinders are more common than single acting cylinders because they work in more applications at almost any angle. In applications where there is assistance through gravity or weight, hydraulic pressure is still often used to cushion the stoppage, control acceleration, and meter the rate of travel. Piggyback cylinders Piggyback hydraulic cylinders use two cylinders in opposite directions that are yoked or welded together. This means that there is twice the stroke while taking up half the space. Piggyback cylinders are idea in applications that have limited space but require a long stroke. Telescopic cylinders Telescopic hydraulic cylinders are made available in single acting and double acting types. Like piggyback cylinders they allow for a long stroke while taking up much less space when collapsed. At Best Metal Products, we believe that every single hydraulic cylinder that we produce meets stringent quality standards, performs or exceeds its rating standard, and functions with a long service life with the utmost reliability, predictability, and safety. If you are an OEM and have been looking for an experienced, trusted hydraulic cylinder manufacturer, do not hesitate to contact us today! What does it mean to "throw a rod"? A friend of mine told me that he had ruined his car engine while driving very fast on a country road. He claims he "blew a rod" and the motor was worthless after that. In more technical terms, could you please tell me what happens when one "blows a rod?" Harv RAY: To set the record straight, in the field of auto mechanics, one doesn't "blow a rod," one "throws a rod." Now that that's clear, here's what happens. TOM: When gasoline explodes in a cylinder, the violent force of that explosion pushes the piston down. The motion of that piston is what makes the crankshaft turn--and ultimately what makes the car move. The metal part that connects the piston to the crankshaft is called a "connecting rod." RAY: When you "throw a rod," it means that one of these rods has literally broken off. When that happens, one of two things occurs. If the rod breaks while the piston is on its way up, the piston keeps going up until it jams itself permanently into the cylinder head. If the rod breaks while the piston is coming down, the broken rod can pierce a hole right through the engine block (like a compound bone fracture breaking through the skin). Either way, the engine is instantly ruined, and you'll have to "blow a wad" to get the car back on the road. RAY: There are two theories about why connecting rods break. The first is divine revenge. This theory states that people who rev the heck out of their cars get what they deserve. We call that the "divining rod theory." Mechanical Atheists, on the other hand, argue that thrown rods have more to do with the age of the car and the accompanying low oil pressure. Since there is a divine element involved, we play it safe by subscribing to both theories. TOM: So if your friend wants his next car to last, he should cover all of the bases. First, he should live a good clean life. That'll cover the "divining rod theory" and all of its corollaries. Second, he should change the oil frequently, and make sure the level is always adequate. That should take care of the Atheists. And finally, he should slow down on country roads so he can enjoy the scenery. That'll satisfy the Audubon Society and the local constabulary.

Why Do You Need a Laptop Stand?

Описание: Why Do You Need a Laptop Stand? Since February of this year, there's been a huge spike in remote working in all industries. Many companies started to expense home workspace purchases to help employees create a productive and efficient remote working workspace. We've seen a huge spike in interest in laptop stands, monitor stands, and other workspace organization tools that help to improve your posture and productivity. So why do you really even need a laptop stand? Here are the top 5 best reasons to use a laptop stand. The most basic reason to own a laptop stand is to improve your workspace ergonomics which in turn helps with posture and relieving back pain, neck pain, and save you from further stress issues later on. The laptop stand will raise your screen to eye level, preventing strain on your neck and back. When you're sitting at your desk for 8+ hours every day, a downward perspective at your laptop can seriously injure your neck in the long run. Instead of stacking books and boxes to raise your laptop stand, purchase something that will create a natural viewing angle. Whether you're a marketer, developer, designer, or even working in finance and accounting, you're typically typing on your keyboard. Whether you're a marketer, developer, designer, or even working in finance and accounting, you're typically typing on your keyboard a lot throughout the day. Laptop stands with the right angles allows for less stress on your wrists as you're typing throughout the day. If you prefer to use a separate keyboard with your set up, laptop stands make it possible for you to adjust your workspace to your liking. I'm sure we've all experienced that dreaded sound of your laptop fan going into overdrive and your machine burning your leg. For those who work with heavy softwares or does any sort of rendering work, it's a terrifying moment when your computer freezes up and you don't remember whether auto-save was turned on. Keeping your laptop ventilated properly can not only prevent these scenarios from happening, but it can also improve rendering speeds and maintain the computer's longevity. Not only do laptop stands elevate your laptop from a solid surface like your table, many of them actually have strategically placed ventilation to help encourage airflow. A messy workspace filled with wires and cables is a surefire way to increase anxiety and stress for the typical worker. Not to mention loose wires have been the key culprit of many horrible computer accidents. A messy workspace filled with wires and cables is a surefire way to increase anxiety and stress for the typical worker. Not to mention loose wires have been the key culprit of many horrible computer accidents. A good laptop stand will include a proper cable management system such as a feeding hole in the back and space under to store any unused items. Just route your cables underneath and through the back of the stand to maintain a clean and organized sightline and workspace. Can a verical laptop stand damage the laptop? I have replaced my desktop workstation with a 17" laptop, and it is ergonomically terrible, the solution was to use an external keyboard and mouse, but still it would stay way below eye level, some people then suggested a vertical laptop stand so i got the cheapo one below. I have searched like crazy on the web for some info or reviews to make sure that it will not cause any kind of damage to the laptop like straining the hinges or any other component by standing in that position, and i could not find anything. Does anyone here have any kind of experience with this kind of support?Can it cause any damage to the laptop? The laptop will stay on the support 24/7 and with the lid opened pretty much 8-12 hours a day. I can't see any reason why this would damage the screen or lid. The lid is designed to stay open in any position. Mounted as you show it most of the weight of the lid is carried vertically on the hinges. You should be careful not to block the fan vents if you have them. That will lead to overheating. Hard drives can generally be mounted in any orientation. This site discusses hard drive mounting. The consensus is the orientation doesn't matter. So I can't see this causing any problems. If you find yourself constantly using your laptop as your desktop computer (i.e. full time workstation) then you really should consider at the least an external monitor and keyboard / mouse. At best you would get a dedicated desktop computer. I don't believe that that stand would cause any sort of strain on the computer. In fact keeping it elevated will probably help keep it cooler, increasing the longevity. Why you should use a monitor arm for better productivity and posture We're a diverse group here at Android Central, but we all have one thing in common that's a big part of our lives: we work from home, putting in long days in front of a computer screen. We're always trying new things to be more productive and make work easier, but one very simple thing can have a huge impact on both your productivity and your health — putting your monitors up off of your desk. Monitor arms have a lot of benefits to anyone who works at a desk as well as people who spend a lot of time doing anything at a computer. Things like gaming or just surfing the web are all better when you're more organized and not craning your neck to see what's on your screen. With Black Friday being the best time to buy a computer monitor, it's also the best time to get a mounting arm to put it in the right place! The biggest benefit of using a monitor arm is the ability to change the height, depth, and angle of your display. This allows you to put your screen in the right place to prevent you from straining your neck and your eyes whenever you're at your desk for an extended period of time. A monitor arm will put your screen or screens directly in the center of your field of vision so you're not constantly looking up or down. This helps a lot in preventing strain-related pain in your neck and back and keeps your eyes where they need to be. Because things are where they should be, your posture is improved, too. When your display is too high or too low you might slouch in your chair or sit too far forward. A good computer chair is designed to support your back and promote good posture, but sitting in it incorrectly does neither, and actually can cause more issues in your shoulders or lower back. If you use a standing desk, this is even more important. You need the desk surface in the right spot for typing and using a mouse, but usually, that's too low for your monitor and you end up looking down all day long. When you put your displays up on a good monitor arm, you can get them at the right height. Another big bonus is the extra desktop real estate. Most monitors come with a sizable stand designed to keep them from tipping forward or back. That means a lot of the back of your desk is taken up by them and everything else you need or want is pushed forwards. With a monitor arm that mounts to your desktop or to the wall, you can reclaim that space. Maybe you want to keep it free and go for the minimal and clutter-free look. Or maybe you need a place for pencils or your phone, or even something like a PlayStation 5. Either way, once you get your monitor's feet off the desk the room is there for you to do whatever you like. Buying A Monitor Arm? A monitor arm is a great accessory you can add to your computer desk from additional workspace to increase ergonomics, there are lots of positives associated with them. And when it comes to ergonomics, it can make a significant difference whether it is your computer work desk or gaming station. They can be very beneficial for a productive work environment, maximize your workspace, and keep you away from physical issues. A computer monitor arm is a piece of hardware that helps you adjust your computer monitor. It can be attached to the desk and to the back of your computer. A monitor arm helps you adjust the viewing angle, height, and depth of the computer monitor so that you can work comfortably without having to adjust too many different things on your desk. It is very useful to hold the monitor in place so that it doesn’t move around too much and you can sit in a more ergonomic position when you’re working. So, when the monitor is set up correctly, you will do less work and have less fatigue working at the desk. This is how it makes sure that you can prevent future expenses from neck, spine, back, and shoulder pain or soreness. Moreover, there are several types of monitor arms out there for different setup needs, but it helps you be more comfortable when working in any work environment. What are the main types of monitor arms? For any typical computer monitor, you can find these 10 types of monitor arms in the market:Wall Mounted – This type of computer monitor arm mounts onto a wall and efficiently maximizes the space in a limited workspace. Gas or Spring Arm – These types of monitor arms are easily adjustable but more expensive and can’t hold heavier monitors. Mechanical Spring – These types of monitor arms last longer, operate more easily than spring arms, and are also less expensive. Clamp Mounted – This type of computer monitor arm fastens to the edge of a desk via C-clamp. Grommet Mounted – This type of computer monitor arm attached to the edge of the desk through a hole and screwed underneath. Post Mount – This monitor arm is attached to a desk from a single column via a grommet mounting system and allows you to set the monitor at your preferred height.Stacked Mount – This monitor mount type is similar to the post mount but the monitors are organized one on top of the other. Rail Mount – This monitor arm is used especially when multiple computer monitors need to be organized in single or multiple rail options. Laptop Arm – This type of arm is designed to support a laptop. Mixed-use Arm – This type of computer monitor arm uses dual arms with one arm holding the monitor and the other arm holding a laptop.

Can You Row a Jon Boat?

Описание: Can You Row a Jon Boat? As most boat owners will know, there are times when rowing becomes a necessity. Should an outboard motor break down or the use of a motor is prohibited, in extremely shallow waterways for example, then rowing becomes the preferred method of maneuvering a boat around. Most Jon boats are not manufactured with oar locks. So, when it comes to a Jon boat can it be rowed? You can row a Jon boat. Some Jon boats may need to be modified by adding oarlocks before rowing can be achieved. Certain conditions will affect your ability to row a Jon boat effectively. Rowing styles, such as ‘canoe style’ with a single paddle or double-paddle, and oar rowing have different levels of practicality. Is it possible to row a Jon boat? A Jon boat is a flat-bottom boat sometimes made from hardwood, plywood or fiberglass but more commonly made from aluminum. It is designed perfectly for shallow, calm waters, as the practically flat hull enables the boat to ride on the surface of the water exceptionally smoothly when it is powered by a motor. Its shallow draft also means it can easily traverse extremely shallow waterways where many other boats could not access. Although rowing a Jon boat may be beneficial to those who want to enjoy a quiet family day on the river or lake it is most beneficial for fishermen and especially for duck hunters. As long as you use the correct oars and oarlocks. A Jon boat is the preferred vessel for fishermen and duck hunters because it can easily access shallow waters thus making it perfect for use in shallow rivers and lakes. A Jon boat can also easily gain access to shallow river banks. Obviously in such circumstances using a motor is impractical as the noise could alert the prey to the presence of hunters.However, this is not the only time when using an engine is inadvisable. Because a Jon boat is designed to access shallow waterways this means you may find yourself in a situation where using an outboard motor is not just impractical but is actually impossible due to the extremely shallow water and very close proximity of the river bed and rocky obstacles that may lie there. Therefore a Jon boat allows fishermen and hunters to access very shallow water and to access areas with stealth. So obviously the best solution in these circumstances would be to use some form of manual propulsion, such as rowing. But is a Jon boat capable of being rowed? The simple answer is “yes”. Though it may not be as easy a task to undertake as it would be with other boat types. When a Jon boat is powered by a gas motor the boat performs very well under calm conditions but under oar-power the same boat may not be as straight forward to maneuver as you might imagine. Aluminum vs. Fiberglass Boats Modern boats are most often constructed of fiberglass, but aluminum is the best material to choose for a workboat. Aluminum is more durable than fiberglass, which is prone to breaking or cracking from impact. Aluminum is more resistant to punctures also. Though sharp objects hit with enough force can puncture an aluminum hull, it is less likely to cause major damage. Plus, aluminum boats do not deteriorate and weaken from sun exposure like fiberglass boats, which can help extend the operational life of the boat. Aluminum boats offers all these advantages while still maintaining a comparable weight to fiberglass boats and therefore provide similar speed, fuel burn and seakeeping. Aluminum Boats: Debunking the Myths Myth: An aluminum boat will corrode from electrolysis overtime. Fact: A certain amount of galvanic corrosion is unavoidable, but a properly galvanically protected aluminum boat will not suffer more than surface corrosion during its lifetime. Silver Ships conducts galvanic testing during all builder’s sea-trials. We only deliver a boat once it has been determined to be in the galvanic protected range. Additionally, marine grade aluminum is more resistant to galvanic corrosion than other aluminum alloys. Silver Ships uses only 5086 alloy Marine Grade Aluminum plate for our vessels, as it is the highest quality marine grade alloy. For further protection, we often include galvanic monitors that continually check if a boat is still in the protected range once in operation. Silver Ships has installed several of these for past customers.Fact: A properly built aluminum hull with a true keel and welded frames is no louder than a fiberglass boat. This common misconception comes from low-end aluminum skiffs built from thin aluminum sheets that are riveted together, or a welded aluminum boat lacking enough welding to secure the hull and side shell to the hull structure. Myth: Aluminum has a higher carbon footprint than fiberglass. Fact: A well-built aluminum boat will last a lifetime if properly maintained. Aluminum boats require less overall maintenance than their fiberglass (or wood) counterparts. This makes aluminum more sustainable than fiberglass over the lifetime of the vessel. Plus, aluminum boats can be easily and cost effectively recycled at the end of their useful life to become other aluminum products. Myth: Fiberglass boats look better and have a unique hull shape that benefits the ride. Fact: Fiberglass boats can be molded into any shape. However, using modern 3D CAD software and robotic routers, modern aluminum boats can be built into more unique hull shapes than in the past. Additionally, aluminum boats can be designed and affordably built as a custom “one off” vessel unique to the customer’s needs. Every fiberglass boat requires an expensive mold that makes it unaffordable to build just one boat. Aluminum Boats: Everything You Need To Know Tin Boats: As Light As A Feather Aluminum boats (aka tin boats) offer a wide range of uses from fishing to entertainment, sports, and recreation, to day trips for both experienced and novice boaters. They have excellent riding characteristics, and because aluminum boats are often light, they are often speedy even with a lower-powered engine. Tin boats typically range between eight and twenty-four feet. What Activities Are Aluminum Boats Used For? As far as family day boats on calm or inshore waters are concerned – aluminum boats are a great choice and ideal if you’re a beginner just getting into boating. This is because they are very easy to run and operate with great maneuverability and handling. Consider choosing a smaller model if you intend to use the boat as a learning platform. Recreation is vital for our self-fulfillment and happiness. Anybody who spends time on the water gets that little bit more disconnected from the ‘on-the-go-24/7’ culture that we have created. On a small to mid-sized aluminum boat passengers are close to the water, and often feel more connected to the natural habitat around them. Plus, many aluminum boats with adequate power can even be used for casual tubing, skiing and wakeboarding or water skiing. Every moment you’re on a tube or wakeboard is a moment less spent on your phone. Of course, if you’re serious about wakeboarding and water skiing you’ll want to look into a dedicated wake boat, but for families looking for all-around versatility and ease-of-use, aluminum boats can often prove more than enough. Tin boats are a favorite among freshwater and saltwater anglers who find it easy to target shallow-water bass or crappie, salmon, trout, panfish, and catfish in lakes and rivers on these boats (due to their shallow draft and lightweight construction). There is ample storage aboard to customize your boat for a day of fishing, and expert anglers can buy a boat ready-made with rod racks, livewells, and castings decks. As aluminum fishing boats are lightweight and easy-to-handle they are a popular choice for boat owners that frequently cruise and fish in shallow inland waters. However, they do come in a variety of hull shapes, sizes and designs. Flat bottom utility boats made of aluminum are ideal for hunting, hauling lumber up streams and rivers and other tasks. These types of aluminum boats actually sit on top of the water, due to their flat shape underneath, as opposed to cruising through it like other aluminum boat hull shapes. These boats are often used for bass fishing, catfishing and similar types of species and habitats by specialized anglers. They are easy to maneuver and help to get you through tighter spots. If you do bump the boat on a stump, log or rock, you can rest assured that any dents are easy to repair, unlike fiberglass. Top Ten Reasons to Choose Alumacraft: 1. A Greater Selection of Boat Sizes Choose from 20' 8" long, high-performance, deep-V boats to 10' flat-bottom jon boats. Alumacraft boats are available in a huge selection of sizes, shapes and styles for an endless variety of uses and budgets. You name it, we’ve got it. 2. The Alumacraft Ride Pros call it "the Alumacraft Ride," and these guys have driven virtually every boat on the market. They tell us the Alumacraft Ride is drier, quieter, smoother and more responsive. Experience the exceptional ride of an Alumacraft—it doesn’t get any better. 3. Superior 2XB Aquadynamic Deep V Hull The aqua-dynamic surface of our gull-wing-shaped design results in quicker planning, better handling and superior boat control in even the harshest of weather conditions. Full-length double plating means twice the strength and protection all the way to the transom (bow only on select models), dramatically reduce sound and vibration, and there’s minimal flexing that can adversely affect handling. 4. Industry-Leading Mod V and Flat Bottom Jon Hull The all-welded and riveted jons can take a pounding. The heavy-gauge aluminum and stronger and wider ribs, make the entire boat tougher and more rigid. Ribs are positioned on narrow 12” centers. This results in more ribs making the hull stronger the entire length of the boat. 5. One-Piece Hull Construction One-piece construction delivers superior strength over the competition’s two-piece hulls. The seamless hull allows for proper keel placement assuring the prop turns in pure non-aerated water. 6. Heavier Gauge Aluminum All Alumacraft boats, whether it’s the all-welded jons or one of the riveted tournament models, are made with heavy-gauge, top-quality, 5052 marine-grade aluminum. That’s why you see Alumacraft boats that have been on the water for years and years. They last longer. 7. All-Aluminum Transom All-aluminum transoms are lighter and 130% stronger than wood transoms. The stronger transom minimizes racking and vibration, providing a more durable mounting surface for today’s larger, more powerful outboards. 8. Larger Aircraft-Grade Rivets Inherent strength is greater with larger rivets. Larger rivets mean stronger rivets. Stronger rivets mean fewer rivets are needed. Fewer rivets mean fewer holes need to be drilled, significantly reducing the chance of ever popping a rivet. 9. Highest Quality Paint Job Automotive-quality Base Coat/Clear Coat paint is stronger and more resistant to fading from ultraviolet light. Even damage like dock rash or scratches can be easily repaired without having to repaint the whole side of the boat. 10. An Overall Better Fit and Finish Look real close. You’ll see a tighter fit, smooth, even welds, larger rivets, and precision construction throughout. These are boats you’ll be proud to call your own. Better Built, Better Ride, Better Value. Boats Life Span: How Long Do Boats Last? Precisely Answered Including All Boat Types You know that boats typically float on water and stay in moist environments most of the time. Won’t it damage the boat, reducing the boat’s life? How long do boats last? First, let’s see the average life span of boats.On average, boats last around 10 to 25 years. But, the life span can vary from 5 years to as high as 100 years (for big ships), depending mainly on the materials used in construction and how often the boat is subjected to regular maintenance. The Boat’s usage is also vital in deciding the life span.So, a boat can last from as little as 5 years to up to 100 years or more. However, the top figures are only applicable for big boats (ships), not for small boats. Sometimes the boat may not even last for few years if it is poorly maintained.

What is PPR Pipe & What is it Used For?

Описание: What is PPR Pipe & What is it Used For? Since its development in the early 90’s the application of PPR pipe has become commonplace, due to its durability, cost effectiveness and long service life. As a manufacturer you may be curious as to why some companies choose to produce PPR over PVC and PE pipe. In this article we will cover the basics of PPR pipe, its features, advantages, and its most common applications. PPR pipe is a straight and rigid cylindrical pipe, made from Polypropylene Random Copolymer plastic, produced through a continuous extrusion process. They are commonly offered in green or white color, and in outer diameter sizes ranging from 20mm to 110mm making the pipe walls far thicker than PVC. PPR pipe is accompanied by a series of connection fittings, parts, and accessories available for every pipe diameter. The thermal conductivity of PPR is very low, meaning temperature cannot easily be conducted from the outside environment to the liquid in the pipe, and vice versa. This factor reduces heat loss or gain during the transferring of hot or cold fluids respectively, resulting in energy efficient systems and lower insulation costs for PPR piping. Long Service Life & Durability PPR piping systems can remain functional for over 50 years, at a wide range of fluid and environmental operating temperatures. Moreover, PPR pipe exhibits excellent durability in both hot and cold water systems. Firstly, it can endure the temperature and pressure strain of hot water systems. At the same time PPR pipe is able to structurally withstand impacts even in cold weather installations without any risk of cracking or breaking, unlike other common types of plastic piping. The inner surface of PPR pipe is very smooth and boasts a very low friction coefficient, compared to traditional types of piping. This results in a reduction of pressure losses during fluid transport and distribution, further contributing to the energy efficiency of PPR piping systems. Moreover, unlike metal pipes PPR does not flake or scale, making them safer to use. Chemical & Mechanical Endurance Compared to traditional plastic piping systems, PPR offers very high resistance against abrasion by hard particles. This is especially important in cases of well water or industrial applications, where the transferred liquids may contain abrasive particles. Moreover, unlike traditional metal piping, PPR is inert to most electrolytes and chemicals, over a wide range of temperatures. This electrolytic and chemical inertness makes PPR piping safe to use in cases of high water salinity (eg. in pool applications that use sea water) or even highly corrosive chemicals (eg. in industrial applications). Ecological & Economic Efficiency Due to the low weight of PPR pipe, their transport, handling, and installation doesn’t require high amounts of energy consumption or manual labor. At the same time they are very easy to cut, join, and work with, making them even more economically sustainable. Moreover, joining PPR pipe and fittings is performed solely through heat and doesn’t require any additional chemicals or materials. All of these factors contribute to PPRs low environmental impact and usage cost. PPR Pipe Applications The durability, economical, and ecological advantages of PPR has resulted in it being used for an increasing number of diverse applications in recent years. Most common PPR pipe applications include: Hot and cold potable water piping in residential, industrial, and public installations. Industrial piping for transferring water, sanitary liquids, liquid food products, compressed air, and aggressive chemicals eg. highly acidic or alkaline solutions. Building central radiator heating water, usually in a circular loop piping arrangement.

Introduction PVC Pipe And PPR Pipe In recent years, with the continuous progress of social economy, the construction industry, municipal engineering, water conservancy engineering, etc. continue to develop. PPR pipes and PVC pipes have also been widely used in these industries. So since these pipes can be used, what is the difference between PVC pipe and PPR pipe? The full name is Polyvinylchlorid drainage pipe, which is a kind of vinyl polymer material. PVC pipe is a kind of pipe product with strong toughness, good heat resistance and good ductility. It consists of an upper layer, a middle layer and a lower layer. The upper layer of the PVC pipe is a layer of paint film, which plays the role of waterproof and anti-aging; the middle layer is the polyvinyl chloride layer, which is the main base layer; and the lower layer is the back coating adhesive Agent. There are many types of PVC pipe specifications, because its uses can be divided into two types: drainage pipes and line pipes, so there are many categories of products. The commonly used home decoration is 32-50mm, 75-110mm. The full name is polypropylene random copolymer which is great for water supply pipes (PPR) has good toughness, high strength, excellent processing performance, good creep resistance at higher temperatures, and has the unique advantages of high transparency of random copolymer polypropylene. The interface of the PPR pipe adopts hot-melt technology, and the pipes are completely fused together, so once the installation and pressure test pass, there will be no longer aging and water leakage like aluminium-plastic pipes. What is the difference between PPR pipe and PVC pipe? 1. Different raw materials PPR pipe is mainly made of copolymer polypropylene, so PPR pipe is also called type three polypropylene pipe, and PVC is made of polyvinyl chloride material. 2. Different wall thickness The wall thickness of PPR pipes is divided into four parts, six parts, etc., the wall thickness of the four parts is 2.3mm, and the thickness of the 6 parts is 3.5mm. PVC pipes are calculated with a diameter of 6mm and a wall thickness of 2.0mm, a nominal diameter of 8-10mm and a wall thickness of 2.5mm. In the same pipe diameter, the wall of the PPR pipe should be thicker 3. Different prices Due to the different wall thickness of the pipe, the price will vary. In addition, prices vary from place to place. Under normal circumstances, the price of PVC is lower than that of PPR, and low price is also an advantage of PVC materials. 4. Different application fields PVC pipes are used in many industries such as building materials, packaging, and medicine. Among them, the building materials industry accounts for the largest proportion, at 60%, followed by the packaging industry, and there are several other small-scale applications. PPR has a wide range of applications: ①The cold and hot water system of the building, including the central heating system; ②The heating system in the building, including floor, wall panels and radiant heating system; ③The transportation of city gas; ④ Urban and rural water supply and drainage system; ⑤The pure water supply system for direct drinking is also extremely safe and sanitary; ⑥ Central (centralized) air conditioning system; ⑦Industrial piping systems for transporting or discharging chemical media; ⑧Pipe system such as gas path used for cylinder transmission; ⑨ Agriculture such as irrigation or spraying of pesticides; ⑩Power and optical cable sheath. 5. The color is different The toughness of PPR pipe is better than that of PVC, and the color of good quality is bright, others are light creamy yellow, and the color of poor quality is chaotic. The PVC pipe is milky white, the material is harder than PPR, the cross section has no light, but the outer surface is shiny. 6. Different performance The installation of PPR pipe is very convenient, because PPR has good welding performance, whether it is thermal welding or electric welding machine, it is very convenient. PVC is relatively heavy and its corrosion resistance is better than PPR, but it cannot withstand high temperatures. It is often used for cold water transportation and cannot be hot-connected during installation. It can only be bonded with PVC glue. The cold water transportation service life can reach 70 years. Which is better, PPR pipe or PVC pipe? If you are home improvement, it is recommended that you choose PPR pipes, because PPR pipes are better than PVC pipes in terms of various properties, and the home needs hot water. PPR pipe also has the characteristics of good corrosion resistance, sanitation and non-toxicity, small expansion force, and firm connection of the system, which is more suitable for home improvement and water supply. The only disadvantage of PPR and PVC is that the price is slightly more expensive. PVC pipes are more suitable for drainage pipes and are more economical.

Why are school shoes important?

Описание: Why are school shoes important? I believe I was destined to become a Podiatrist from a young age, because one of my favourite days of the summer holidays would be when Mum would take my brother, sister and I school shoe shopping! Having gone to a primary school where we wore black leather school shoes four days a week, it was important that we were 100% satisfied with the comfort and fit before purchasing. Personally, I think there are many advantages to a uniform policy that requires wearing school shoes. I like the idea of all students looking the same, and not feeling embarrassed that they don't have the latest sports shoe. A simple black or brown school shoe puts all children on an equal playing field and prepares primary school aged children for the likely high school regulations and then even into working life. School shoes can be regularly maintained for extra life, such as using a polish to reduce scuffs, replacing frayed laces, having a Cobbler repair soles and even replacing the sock liner. Allowing your child to participate in regular polishing and caring for school shoes fosters a sense of responsibility for their own property and promotes sustainability. School shoes are often made with a variety of fasteners such as laces, Velcro or buckles. This creates options for children of varying ages and abilities to independently apply their own footwear. Children can progress through fastener options as their fine motor skills improve over time. Appropriate school shoes can also help protect children's feet from the elements, a covered in leather shoe is protective against the cold and rain, a solid grip on wet ground and a quality leather allows breathability on a hot day. A thick sturdy sole protects our kids' feet should they step on something sharp and covered in style reduces the risk of foreign objects such as gravel or tanbark ending up inside the shoe. The benefits of quality school shoes are endless, but in my opinion the dominating factor is how comfort can improve mood, concentration and ability to learn in the classroom.How to buy the best school shoes？ Researching which school shoes to buy can leave parents feeling like they're failing at comprehension. Why are some so expensive? Are the cheaper ones OK? Buckles, Velcro or laces? And why-in-the-name-of-all-that's-holy do my kids wear them out so quickly? It's an annual dilemma for parents of school-aged children (and sometimes a biannual dilemma if they have a growth spurt) – and it can be a costly decision to get wrong. The bones in young children's feet don't fuse together until puberty. This means their feet can lack muscle strength and be prone to hypermobility, which is why they need firm, supportive shoes to help protect them while they're growing. "A good school shoe provides a stable home for immature bones," says Charlotte Bodell, a podiatrist and spokesperson for the Australian Podiatry Association. "Without that support, children are in danger of developing flat feet, sore knees, shin splints and even back pain. A good shoe that fits properly is important." Bodell adds that good footwear alone isn't enough. "It's also important for children to carry out regular daily exercise to keep their feet and lower limbs strong and healthy," she says. Kids' feet grow quickly and can change shape as well as size. Experts recommend doing a size check at these intervals: One to three months up to the age of three years.very four months up to the age of five.Every six months until your child stops growing completely. How to measure your child's feet at home Whether you're minimising shopping trips because of COVID-19, or you can't get to a shoe store, there are ways to measure your child's feet at home so you know which size to choose. Clarks sells an at-home foot gauge, which you can use to measure the length and Williams offers an online measure and fit service called Strutfit. This guides you through the process of taking pictures of your child's feet to be uploaded and analysed. It will then recommend a size. DIY foot measurements Alternatively, you can follow this general step-by-step guide to measuring your child's foot, then use those measurements to find the right size shoe for whichever brand you're interested in. (Most stores will have a size guide on their website.) Children's Shoes Until recent times, footwear made for children generally mimicked the idiosyncratic styles of the adults of their time and place (taking into account the special characteristics of the feet of infants and young children). It was not until the twentieth century that footwear highly divergent from the dominant adult prototype evolved specifically for children. However, in premodern times there were some circumstances concerning children's footwear that are of historical interest. Ancient Greece In ancient Greece, sandals and slipper-like shoes predominated for both children and adults. Boys were "sandaled" around the age of seven when they first left their homes for school, a rite of passage similar to a boy's receiving his first pair of breeches in later eras. Young girls making their first departure from home, which took place with the girl's marriage shortly after reaching biological adulthood, also went to the shoemaker's for their first pair of sandals. A survey of Tanagra terra-cotta figures from the first half of the third century B.C.E. suggests that young children, perhaps specifically girls, wore slippers before their official departure from family life. There is much debate surrounding the question when and if children in ancient times were shod. Nineteenth Century Baby Booties In the nineteenth century as the making of shoes became more systematic, particularly in New England, evidence emerges of the development of particular styles of shoes for children. The Reverend Richard Manning Chipman noted, for example, that "cack" was a specific term developed in Massachusetts around the year 1820 for a baby's soft leather-soled heelless shoe. On the other hand, the Oxford English Dictionary discloses that the word "bootee" or "bootie" did not occur in popular English usage as a description of infant's shoes until its appearance in a Sears, Roebuck and Co. catalog in 1929. Throughout the nineteenth century, periodicals encouraged women to try their hands at creating shoes for their young children. Patterns appeared in Godey's Ladies' Book (1830-1898), and Peterson's Magazine (begun 1842). In the anonymously written The Workwoman's Guide (1838), the author gives patterns and sewing directions for baby's first and second pair of shoes, as well as a pair made of ticking material (A Lady, pp. 173, 174). One hundred and fifty years after Monsieur Rousseau encouraged the possibility of childlike-children, footwear began to be developed specifically for them, albeit in the form of variations on already existing adult shoes. In 1890, George Warren Brown opened the Brown Shoe Company in St. Louis, Missouri, but it was not until the 1904 World's Fair that his variation on the Oxford tie for boys came into its own. In that year a young executive from Brown's company met artist Richard F. Outcault and the "Buster Brown" shoe was born. Of equal importance is Buster's sister "Mary Jane" who gave her name to the ubiquitous girl's low-strapped shoes. The twentieth century increasingly saw shoe manufacturers appealing directly to children through such techniques as tie-ins with television shows such as Howdy Doody, The Lone Ranger, various cartoons, and Sesame Street. The 1980s saw catalog and department store giant Sears, Roebuck and Co. introduce Grranimals, a line of children's clothing with accompanying footwear that had strategically placed emblems that aided children in creating coordinated outfits on their own. White Sneakers Every Girl Must Own To Match With Every Outfit White sneakers are definitely a must-have in every girl's wardrobe because it's extremely versatile and can match with almost any kind of outfit. Plus, sneakers are just so comfortable and if high heels are not your kind of thing, it won't hurt to perhaps have more than one pair of white shoes in your collection! While white sneakers are a dime a dozen, here are some classic ones that every girl must own.What's Up with Your Son and His Sneaker Obsession? When little boys get into their first superhero costume, magic occurs. They know they have super powers. They think they can fly, bend steel and outrun the wind. A few years later, when it dawns on boys that maybe their Batman capes don’t give them these powers, they seek out something else. Sneakers. A boy's love affair with his “kicks” is intense. If you’ve ever seen a boy lace up his new sneakers (that word moms usually use) and run around the shoe store, you know what I mean. In the right pair, boys believe they will jump higher and run faster. You can see it in the gleam in their eyes—they are invincible. But there's nothing new about shoes being a big deal for boys. From Vans to PF Flyers to Chuck Taylors (“Chucks”), shoes matter. The love of kicks is deep. And for this generation of boys, it's basketball shoes. The first Air Jordans came onto the market in 1985, right after Michael Jordan first laced up those black-and-red shoes to match the colors of the Chicago Bulls. David Stern, the NBA commissioner at the time, fined Jordan five thousand dollars each time he stepped out on the court because his shoes didn’t have enough white on them. There was nothing David Stern could have done to make Michael Jordan or his shoes look cooler. Jordan was breaking the rules and he looked good doing it. But why else are shoes such a big deal for boys? Shoes are the fashion choice that all boys can participate in without being teased. When you go with your son to a store like Foot Locker and the salesperson in that black-and-white striped shirt comes over to your son, what does he ask? Does he ask what size shoe your son wears? No. The smart ones say, “Hey, man, what are your colors?” What other article of clothing could that happen with? Where else could that question be asked without drawing embarrassment from your kid? The last time I went with my sons, I had a hard time holding back my laughter as I listened to their intense discussion with the salesman. I watched them wander in front of the wall of shoes, saw their intense gaze and subsequent handling of the shoes while they each stared off visualizing their future greatness on the basketball court. The entire thing was completely ridiculous—a fact that I kept to myself. What isn’t ridiculous and what parents need to be very aware of, is that shoes are a huge indicator among boys about status and money. The shoes boys most covet are heavily marketed to them and extremely expensive. (Nike Kobes are about $170 and LeBrons can go up to $250.) If parents are willing to pay for them, that says a lot about how they’re buying into the marketing campaigns that are targeting our boys and, by extension, our wallets. Also keep in mind that boys often have judgments about who has the right to wear these shoes. As in, if you wear them but you can’t hold your own athletically, boys are going to make fun of you to your face or ridicule you behind your back. I am writing about this to suggest that when your son is begging for new shoes and spends hours looking at his various options online, don’t make fun of him or belittle his apparent superficiality. Instead, see this an opportunity to talk about financial responsibility and perception of his image. Tell him how much you are willing to spend. If he still insists that he has to get expensive shoes, tell him he has to use his savings or work to pay for the rest. Then ask him how he thinks his life will be better if he has the shoes he covets and really listen to his answers, because he is giving you a window into his world.

What Is a Load Bank?

Описание: What Is a Load Bank? Testing power sources, such as uninterruptable power sources (UPS) and diesel generators, ensure that these devices will provide the required amount of power when needed. A load bank tests these power sources by developing an electrical load. Various load configurations permit testing under different conditions. A load bank is a self-contained device that has the load elements, controls and cooling systems it needs to operate built-in. Power is delivered to a load bank, which then consumes the electrical power by applying it to a power source and either converting or dissipating the source's power output. Load banks use the energy produced to protect, support or test a power source while a "real" load or actual building load uses energy output productively.What Is the Purpose of a Load Bank?Load banks ensure the quality and reliability of your emergency power sources. They verify the accuracy of the generators' output capacities by creating a variety of different loads that replicate real-world use. If you own, sell or operate generators, especially for backup power, you need to test them regularly. Without testing, you cannot be assured the generator will provide the required power when the lights go out. Many facilities require load tests of all backup power sources. Prime power generators benefit from load bank use, particularly in lightly loaded situations. What Does a Load Bank Do? A load bank develops an electrical load. Load banks are absolutely essential for emergency sources of power, as they verify the power source's rated output capabilities before the power source is called into actual use. A load bank should mimic the real load a power source would see during an actual use scenario. The devices usually have different levels of load, which allows critical systems to be tested under a variety of conditions. Who Uses Load Banks? You need this type of testing bank if you have generators or uninterruptable power sources in your business. Best practices for testing emergency power sources is regular load bank tests. If you have diesel generators on-site, you may use a load bank to augment lightly loaded situations and keep your generator running properly. Wet stacking occurs when unburned fuel remains inside the system. The unburned diesel condenses and combines with soot in the exhaust system, leading to wet deposits on exhaust components. Left unchecked, wet stacking reduces engine efficiency until it requires a complete overhaul to restore its former power. The best way to prevent this from occurring is to test the generator with a load bank, which enables you to complete two maintenance tasks with one action. Monthly testing is a requirement from the National Fire Prevention Association, in its Standard for Emergency and Standby Power Systems. You must test the generator at full load to maintain the minimum exhaust temperature recommended by the manufacturer. An alternative test allows you to use 30% more than the rating on the generator's nameplate for at least half an hour. A novel use for these banks is for renewable energy sources. The Hawai'i Natural Energy Institute (HNEI) has incorporated a load bank into the power system on the island of Moloka'i. The island could not add more photovoltaic cells because it posed the threat of producing too much electricity and dropping the power produced by the island's diesel generators too low. The addition of a resistive load bank allows the island to add more solar cells because the load bank moderates the amount of power the island gets by absorbing any extra electricity produced.Difference Between Resistive & Reactive Load Banks Load banks come in many different forms based on the load they apply to the power sources they test. Resistive and reactive load banks are two primary forms. Each of these has its benefits for specific situations. Understand the differences between resistive and reactive load banks to find the best options for running tests on your power sources. Resistive vs. Reactive Load Banks Depending on your generators and how you use them, you may need resistive, reactive or both types of load banks. These devices put different kinds of loads on the generators. Resistive models are the most common, while reactive include inductive and capacitive power loads. 1. Resistive Load Bank Uses Resistive load banks draw power from a generator in the same way lights or appliances would. These testing devices work well with generators used for general power purposes that involve transforming electricity into heat or light. Light bulbs, lamps and space heaters are examples of tools that convert electrical energy into heat. These types of load banks draw a specified real power load, in kW, on the generator to ensure the operation of the power supply's cooling system, exhaust and engine operation. They do not test the generator for full apparent power in kVA, which is what a reactive load bank tests. 2. Reactive Load Bank Uses Reactive load banks can simulate inductive loads, often used commercially in construction or in backup power supplies. Inductive loads create a lagging power factor, whereas capacitive loads generate a leading power factor. Of these two types, inductive appears more commonly in objects that turn power into motor operation through magnetism. For facilities that rely on emergency generators to run equipment for business-critical operations or life support, such as data centers and hospitals, reactive load bank testing is the most effective. How Do Resistive Banks Work? Resistor load banks convert all of the applied electrical energy into heat. Larger kW load banks typically have an integrated blower for cooling. Some load bank designs, such as Duct Mounted, do not have their own cooling system but rather rely on cooling airflow from other sources such as an engine radiator. Self-contained resistive load banks are commonly found up to 3,000 kW. For full kW load testing, make sure to choose a load bank with a capacity equal to or greater than the power source at the rated output voltage. How Do Reactive Load Banks Work? Reactive load banks test the full apparent load in kVA of the power source. Though not as commonly used as resistive load banks, reactive models are part of the testing requirements set out by NFPA 110 for nonunity power factor equipment field or factory acceptance testing. Unlike resistive loads that generate a power factor of 1.0 and a load of 100%, reactive has a 0.8 power factor with a 75% load. This difference in power factors and loads leads to voltage drops from the generator of 25% more than from the resistive loads. In this way, reactive load banks test for systems that have a sensitivity to voltage dips. Advantages of Resistive Load Testing Resistive load testing is very common as it is the most cost-effective way to test a power source. For generators, this method checks the ability of the generator to respond at a full load. With the generator producing full power, you can assess the capability of the mechanism's fuel and cooling systems to operate under the effort. Resistive load banks also prevent diesel generators from losing efficiency through wet stacking, which happens when unburned fuel clogs up the exhaust system. By putting a higher load on the generator than it typically experiences, a load bank encourages the engine to burn more fuel, reducing the chances of wet stacking. If the condition has already set in, using a resistive load test at full power can reduce the effects by burning excessive moisture in the engine. Another benefit of using resistive load banks is they allow the generator to exercise its exhaust system to reach high enough temperatures to properly treat the fumes flowing through it and operate at its peak. Additionally, resistive load banks can be used to supplement the actual load on a generator to optimize its performance. Often you will find generators operating at 50% loads or lower, which can lead to wet stacking. Resistive load banks with Auto Load Leveling Controls can automatically add and subtract kW to help maintain a minimum load. Reactive load testing offers some additional benefits that resistive testing cannot and can warrant the extra expense for certain applications. Advantages of Reactive Load Testing Reactive load testing more closely replicates the type of load a generator will experience during typical use in kVA and kVAR. It helps evaluates not only transient loads, but also load sharing and alternator capacity. When doing testing with a reactive load on systems in parallel, you can look for hot spots using an infrared examination of the electrical system. You can also use the load conditions to assess the electrical connections, cables, bus work and other components. Depending on your equipment, you may need both reactive and resistive load testing. If this is the case, we have models that can fulfill both needs. Should you need a unit with the capabilities of both resistive and reactive testing in a single model, we have a solution for you. These load banks have high capacities up to 1,875 kVA and load up to 1,500 kW. Resistive-reactive models do the job of two load banks in one powerful unit. Inductive Load Banks An inductive load bank is normally used in conjunction with a resistive unit to provide a lagging power factor load test. This provides the capability to test the generator set fully at 100% nameplate kVA rating. Inductive load banks add inductance to the load and therefore reduce the PF to less than unity (typically 0.8pf on diesel gen-set). Inductive load banks are rated in kilovolt-amperes reactive (kVAr). A load bank is a device that generates a prescribed amount of electricity draw to test the reliability of electrical switching, generator output, uninterruptable power supply (UPS) systems and cooling in a data center.Rack-mount server-simulating load banks discharge heat while consuming power to accurately mimic the load of a server processing a workload. Data centers test cooling and power supply operation with load banks rather than software simulations for more real-world accuracy, such as air-flow blockage in the rack caused by the server-sized load bank, or dust in the air from improper filtration. Avtron, ComRent and Mosebach are server simulator load bank manufacturers. A load bank test simulates real operation by applying the load in situ, with real temperatures and relative humidity, but it is not an exact reproduction. The load bank only draws power (current and voltage) to test the infrastructure, and then dissipates it safely as heat.Load banks are either portable or fixed. Fixed load banks suit outdoor use, while portable load banks can move around the data center and between sites to test specific power setups. Load banks cannot mimic the random peaks and lulls of real data center equipment power usage, but they can approximate the equipment's requirements in a controlled setting with high levels of accuracy. Load testing should be included on UPS maintenance schedules. Capacitive load banks, or capacitor banks, commonly test UPS and other electronic loads by creating a leading power factor. Some power supply vendors, such as Emerson Network Power and Power Systems Specialists, offer load bank testing as a service. Inductive load banks, by contrast, create a lagging power factor. The third common load bank type is resistive, with a lagging power factor. Resistive load banks, used frequently for industrial purposes, provide equivalent loading on the generator, and are usually portable.

Here are some things to think about when choosing a headband

Описание: Here are some things to think about when choosing a headband Look for headbands in darker colors and more sophisticated prints ( likes leopard or snakeskin). Interesting textures can be quite sophisticated too. Thinner, finer plastic headbands tend to look chic as they are more subtle. Vintage headbands with a twist knot are trending and can be a playful fashion statement. A casual headband ( typically a brighter color) usually says “preppy.” Make sure your outfit is also casual to work with this look. Anything with a traditional bow is very tricky and in most cases are not age-appropriate Scarves tied as headbands are an excellent way to keep your hair back and will give you a boho-chic vibe Avoid any kind of headband that looks like something you’d see a 7-year-old wearing I'm glad you brought this up since headbands have been so popular lately. They can certainly be a good thing to wear when transitioning from one style to another. A headband is great for accentuating bangs. It can flaunt a pixie cut, or show off longer locks quite nicely too. A headband can even become part of your signature style. The problem with wearing a headband after 40 is you can come across looking too girly and juvenile. Up until now, there hasn’t been a wide variety of headband styles, and the majority of headbands out there were sweet and childlike. Now that's changed. I think headbands can be fine at any age, but as a mature woman, I'd steer clear of headbands with flowers, floppy bows, and sparkly little girl styles. Think classy, less cutesy when choosing a headband. This fine resin headband is more elegant. Hair Trends You Should Know About What 2021 hair trends should you know about? Despite the rollercoaster of a year that 2020 was, there's no denying that it was certainly memorable. And while a lot of those memories might have been made at home, that doesn't mean there weren't any good times. Still, 2021 is on track to be much better than the previous year, and that means there are new and exciting trends to look forward to. Sure, you might have lived in the same pair of sweatpants for a while, but that doesn't mean you can't have fun with your hair and makeup. Try a new smokey eye for that Zoom meeting, or just go for it and trim your hair for a wild and crazy Friday night! Despite the fact that no one knows exactly what 2021 will hold, there will certainly be some hair trends you should know about in the coming year. After all, if you are stuck at home more, why not learn new styles and looks to rock once you finally get to leave the house? If 2020 has taught us anything, it's that high-maintenance hairstyles and colors are so not worth it. Sure, you could style your hair every day, but what's the point? If you aren't naturally gifted at twisting your hair into fancy and complicated styles, then why force yourself to? That's one reason many people will be leaning towards a more natural, easy to maintain hair color for 2021, says colorist Richy Kandasamy. "For a lot of clients, this has been a positive reset and they want to embrace their natural hair color or stay as close to their natural color as possible," they told Harper's Bazaar. In the same vein, natural styles and trends will be all the rage as well, as noted by Oribe Principal Educator of Content and Training Kien Hoang. "I'm predicting that spring 2021 will go towards a '90s feel with more lived-in looks," they shared. So, if you don't like trying to pull off the latest hair trends, 2021 might just be your year because natural and lived-in looks will be huge. Reasons Why You Need To Start Wearing Scrunchies Again Scrunchies are back in a big way and I'm loving it. Not only because it takes me back to my childhood (dating myself here), but because scrunchies are really good for your hair! So let's talk scrunchies today. Some of the benefits and then I'll show you some of my favorite new scrunchies I've been wearing lately. 1. Scrunchies Are Good for Your Hair. They won't cause breakage. The layer of fabric around the elastic band means that your hair won’t get tangled and knotted with a scrunchie. I have used good hair ties and no matter what they always pull my hair out. The same goes for my daughter. Trying to take a hair tie out of a 2 year old’s hair is not easy and the hair ties always have hair stuck to it when I remove them. A scrunchie won't do that. The fabric should be soft and it will glide over the strands and not pull and tug. They won't leave kinks. My hair ties always leave kinks in my hair. Especially because I sleep with them on. I wake up every day with a kink and a strange wave in my hair. Scrunchies won't do that. They are so soft and gentle on your hair strands and they shouldn't leave deep kinks in your hair that are difficult to get out the next day. 2. Scrunchies are Fashionable and Stylish. Scrunchies are a true accessory. With all the fun patterns and fabrics, you can change up your look so easily by switching them out. I love all the different patterns and textures that are available now. They make a statement and depending on the pattern you choose can really dress up an outfit! Just like handbags and shoes they can really add to a look. 3. Scrunchies Are So Much Prettier Than A Hair Tie. A hair tie just isn't very noticeable and blends in with your hair. Scrunchies makes a statement… AND wearing them on your wrist is like wearing a bracelet because they are so pretty!! I don't know about you, but I am the worst about leaving a black hair band on my wrist. I'm shocked I made it down the aisle without it on my wrist!! The scrunchie will look pretty on your wrist and it won’t leave an indentation! Your Holiday Hairstyle Deserves A Dose Of Sparkle It's beginning to look a lot like Chr-... okay maybe not quite yet, but it’s never too soon to start planning out your holiday glam. Though the holidays hold much excitement, from the food, to the decorations, and time spent with family, the most exciting part of it all, arguably, are the outfits — not to mention the holiday hair accessories that act as the cherry on top. If you’re thinking a few weeks ahead about what you’ll wear to the numerous holiday parties that you have pending invitations to, don’t forget to include a festive hair accessory to complete the look. Most other months in the year don’t call for sparkly berets and bedazzled headbands, but November through December is your opportunity to pull out all the stops with preppy glam holiday looks. Even if preppy is not your style, there is a holiday hair accessory to match every aesthetic — opt for a sleek bucket hat instead or even a subtle hair pin that’s nearly undetectable, but still adds a bit of shine to your look. Below, see 10 holiday hair accessories that guarantee you’ll be the hottie at every holiday party — or just around the family dinner table. Damage Control: 10 Hair accessories you should really stop using We all love our hair, don't we? It's what gives us character. You might be the type of person who spends hours upon hours each week taking good care of your precious tresses with all the right conditioners and serums, so why spoil all your hard work with the wrong accessories? Indeed, there are many things we should banish from our hair routine. Some may even surprise you. Taking care of your hair is not a simple task, of course, and using accessories will make things just a little bit easier. However, habits such as using a rough towel to rub at your hair and scalp as soon as you get out of the shower is a bad way to start with proper haircare. Reduce the damage done! Discover 10 accessories you need to banish from your life if you want to have beautiful hair! Straw hats, in particular, should be avoided, as your hair can get caught in between the gaps in the material and you may suffer from hair loss due to this. In general, hats can make your scalp accumulate grease faster as it prevents sufficient airflow and breathability. Clothing with embellishments such as sequins will create friction when your hair is let down and loose. This can promote the appearance of split-ends. Be careful of ornamentation such as pearls, glitter, and coarse fabrics. Your hair may cling to these. Pay close attention to the quality of the hairpins you use. To make sure they don't end up damaging your hair, ensure that they have a plastic end cap and that they are protected by a film so they don't end up tugging and clamping on your strands. If this is the case, you should throw them away and find better ones. Bristles made of plastic can irritate your scalp and cause unwanted static. Swap them out with ones that have bristles made of natural materials such as wild boar hair. Clip-in extensions can weigh down your real hair and damage your scalp in the long run. They might end up pulling out your hair and leaving noticeable bald spots and gaps. If you are a fan of these extensions, be sure not to use them every day, especially if you already have thin hair!Elastic rubber or bands with small bits of metal are to be avoided. Your hair can get caught and tugged out painfully when you try to remove such bands. Constantly tying up your hair in elastic bands in styles that are too tight will also aggravate hair loss. Choose bands made of softer fabrics to limit friction.
