Fiberglass Mesh Protects Plaster Layer Surface From Cracking
Описание: Fiberglass Mesh Protects Plaster Layer Surface From Cracking Plastering mesh glass cloth is used for reinforcement surfaces during plastering, installation leveling floors, waterproofing, restoration of cracked plaster in order to prevent cracking or fraying of the plaster. Fiberglass Mesh is a cheap material that does not burn and is characterized by both low weight and high strength. These properties allow it to be successfully used in the formation of plaster facades, as well as use on internal wall and ceiling surfaces. This material is widely used for fastening the surface layer at the corners of the room. Most widely used standard fiberglass plater mesh is the density of 145g/m2 and 165g/m2 for exterior cladding and facade work. Resistant to alkalis, does not decompose and will not rust over time, it does not emit toxic and harmful substances, has a high resistance to tearing and stretching, protects the surface from cracking and improves its mechanical strength. Easy to handle and use. Application of Plaster Fiberglass MeshFiberglass mesh is used to strengthen the surface of the plaster layer all kinds of buildings.This mesh reinforced liquid waterproofing layers slabs and roofs.Fiberglass mesh used to impart mechanical strength filler floor coverings that are different self-leveling properties.Application of glass fiber mesh contributes to strengthening plaster, and the bases used for laying ceramic tiles.Drywall fiberglass not-sticking tape and Fiberglass Self Adhesive Tape are used for combining the joints between walls and windows, door together with our fiberglass mesh to repair the cracks, joints and seams of drywall, plasterboard and other surfaces. Drywall fiberglass not-sticking tape should be used with cellophane tape. Fiberglass self-adhesive tape could be used alone. Fiberglass Chopped Strands enhance value and mix well with fibrous materials such as wood, paper and polyester. They have been specially developed for use in wet-formed mats and veils, which are processed in either acidic or neutral white water systems. Improved mat properties make these products suitable across a diverse range of end-use applications such as specialty papers, filters, printed circuit boards, roofing mats, roof tiles, acoustic tiles and vinyl-coated flooring. Our Wet Chopped Strands offer the following advantages:excellent strength and dimensional stabilityperforming well across a variety of temperature and humidity conditionsbroad chemical resistancequick and uniform dispersion in water-based bonding systems, whether acidic, neutral or basic. Fiberglass Yarns consist of a defined number of E-Glass filaments of a certain nominal diameter, brought together to form a yarn. The structure of the yarn is fixed and protected by a size and a slight twist, generally in Z-direction. Our E-Glass fiberglass yarns are wound on plastic bobbins and supplied in a “milk bottle” shape. Vetrotex glass yarns can be also supplied on beams. The glass composition meets the certification for E-Glass as defined by ASTM’s D578-00 Standard Specification for fiberglass filaments. Fiberglass refers to a group of products made from individual glass fibers combined into a variety of forms. Glass fibers can be divided into two major groups according to their geometry: continuous fibers used in yarns and textiles, and the discontinuous (short) fibers used as batts, blankets, or boards for insulation and filtration. Fiberglass can be formed into yarn much like wool or cotton, and woven into fabric which is sometimes used for draperies. Fiberglass textiles are commonly used as a reinforcement material for molded and laminated plastics. Fiberglass wool, a thick, fluffy material made from discontinuous fibers, is used for thermal insulation and sound absorption. It is commonly found in ship and submarine bulkheads and hulls; automobile engine compartments and body panel liners; in furnaces and air conditioning units; acoustical wall and ceiling panels; and architectural partitions. Fiberglass can be tailored for specific applications such as Type E (electrical), used as electrical insulation tape, textiles and reinforcement; Type C (chemical), which has superior acid resistance, and Type T, for thermal insulation. Whether on a wall or on a soffit, outside corners must be covered with PVC Corner Bead. The material protects the surface and has a slightly raised beaded edge, which keeps the corner straight and acts as a screed while taping. It wasn’t too long ago that square-edged metal corner bead was the most commonly used corner bead, and it may still be today, but the other options really are worth looking into. Today, you have your choice of metal, vinyl, plastic covered with paper, or metal covered with paper. Some types are available in 100-ft. rolls. Bullnose beads are also available in a variety of sizes and have become very popular because they offer an elegant look and are just as easy to install as regular bead.

The advantages of using a mobile hoist
Описание: The advantages of using a mobile hoist This article will discuss the reasons why we use mobile hoists from the basic biomechanical, through to the functional and up to the maintenance of an individual’s dignity.The Hand Hoists we all know and use today stem from a simple design invented by Lord Armstrong in 1845. This invention came out of necessity; an industrial revolution was taking place in the UK with the ever-increasing demands on the coal and steel industries and manufacturing called on a need for machinery to meet the demands of the tools to lift heavier and heavier loads. This simple design often referred to as a block and tackle style hoist, which is still used to help disabled persons in their own homes, in hospitals and residential care facilities today. However why do we use mobile hoists at all? The most basic advantage that using a mobile hoist gives us is that of simple biomechanics. Simply put they impact on the amount of effort required to move a person by the human body and the forces exerted on the body. For example if you have a person that weighs 170 pounds and that individual needs to be moved from their bed onto a care device such as a commode you do not need an equal amount of force to match the 170 pounds but considerably more in order for you to move that person. That is one reason we have Hand Chain Hoists such as the hydraulic hoists invented by lord Armstrong. When lifting a person, the forces required to move them may not move in a straight up or down direction, or side to side, there could be a combination of the both or even rotation forces, all of which will have an impact on a handler’s muscular and skeletal frame. Hoisting a person (animate object) that is dependent on us for their care is not like hoisting a crate of oranges (inanimate object) for example. If we hurt ourselves when lifting a box of oranges and we drop the oranges, we may end up with an injury and a broken box of oranges. The same cannot be said if we were lifting another person and we sustained an injury leading to us dropping the person. This could have catastrophic effects on the individual being dropped and is not a sustainable way to manage a dependent person’s care. Mobile hoists allow us to apply the required amount of force to lift a dependent person with the mechanical forces going through the structure of the Lever Hoist and therefore reducing the biomechanical forces exerted on the carer. Therefore, we reduce the risk of injury to both the dependent person and the carer and increase the sustainability of the dependent person’s care. If we consider the previous section of this article, we start to understand how biomechanical forces work and how mobile hoists can help keep care givers safe. Mobile hoists in part can help to reduce the risk of WMSDs. They do so by offsetting the biomechanical forces at play when we move a dependent person. The use of mobile hoists in institutional settings such as hospitals will be as a result of risk assessment, where moving a person is deemed hazardous. This is in line with the OSH Act (197) which aims to ensure safe working conditions for men and women, which includes Hazardous identification and risk assessment. To ignore these risks as we’re starting to understand can have a significant effect on the workforce. Many health professionals experience WMSDs particularly lower back by moving or lifting their patients (Yasobant S, 2014). This can also cause days off work whilst staff members recuperate from their injuries (Amaro J et al, 2018). So, employers both legally, and from an employee health standpoint need to have Chain Hoists available if staff wellbeing and patient care dictate. As such Mobile hoists provide an easy access, easy to use hoisting solution for employees use. None of us can probably fully imagine what it must feel like to be dependent on another person for our care, especially when it comes to the more personal elements of that care. To be moved efficiently with the patient experiencing as little discomfort as possible increases the options for more dignified personal care. For example, an Electric Hoist may allow someone to access a toilet rather than wear pads to open their bowels. The result being the dependent persons privacy and dignity is better managed and has more options to care. Although institutions such as care homes and hospitals may consider fixed hoists such a ceiling track initially preferable, it is testament to the flexibility of the mobile hoist that many institutions use them. The reason for this flexibility is the lack of need to be fixed to a ceiling or wall and can therefore be transported between rooms. One mobile hoist can service a whole floor, or hospital ward, or an individual’s home at the fraction of the setup, maintenance and running costs of fitting each room with a ceiling track hoist. A Hand Winch is a mechanical device to lift or move heavy objects. It winds wire around a drum (or a spool) while holding the wire rope steady until it needs to be adjusted. Winches are used for backstage mechanics in the film and live event industries. They are embedded in the floor to move large pieces on and off the set when needed. Winches are also used for industrial purposes like towing vehicles or boats or removing heavy rocks, trees, and cumbersome equipment. Pallet Trucks are designed to hold bulky items and automatically weigh anything placed onto the pallet itself.For increased accuracy it’s advisable to position them on a flat surface before selecting a preferred application – be that check weighing, dynamic weighing or another pre-programmed option.Before anything is placed onto the forklift beams themselves it’s important to tare or zero the LCD display. This serves to reset any previous work. Thereafter items can be carefully stacked. A built-in scale will measure the weight and share this on the screen. The more you add, the greater the weight displayed but ensure the load is stabilized for a reliable readings.Unlike many scales, the final load can be moved as one when deploying pallet truck weighing models, allowing for easy loading or stocking on receipt of delivery.

What’s the Difference? Snow Blower vs. Snow Thrower
Описание: What’s the Difference? Snow Blower vs. Snow Thrower Today’s snow removal machines make quick work of clearing the white stuff from driveways and sidewalks—saving your back from the strain of shoveling and tossing aside heavy snow. Yet while the terms “snow blower” and “snow thrower” are often used interchangeably (even by manufacturers at times), the two machines are actually quite dissimilar in terms of power, functionality, and price. We’ve put these two side by side—snow blower vs. snow thrower—to identify six notable differences. Keep reading to find out which snow removal machine is best suited to your climate, property, and budget.A snow blower is more powerful than a snow thrower. A Snow Thrower is single-stage machine, meaning it gathers snow and tosses it out a chute in a single motion. The power generated by a horizontal spinning auger picks up the snow while also creating the force that expels snow out of a discharge chute, usually to a distance of 15 to 25 feet away. A snow blower works in two stages; like a snow thrower, it has a rotating auger to scoop up snow, but the snow is then fed into an impeller, which is akin to a powerful fan that launches the snow up to 35 feet away, or farther. At the even more powerful end of the Snow Blower spectrum are three-stage blowers that feature accelerators that chew through hard-packed snow and even ice, crushing it and feeding it into a mighty impeller that can launch snow up to 50 feet away.Snow blowers remove a wider swath in a single pass. Single-stage snow throwers are on the smaller side, and they remove snow in swath widths between 11 inches and 22 inches, depending on the individual machine. Two-stage snow blowers can clear up to a 26-inch swath of snow, while three-stage ATV Snow Blowers can remove as much as 30 inches of snow in a single swath. In areas that get frequent snows, a snow blower that removes a wider swath will significantly reduce the amount of time spent clearing away snow. Snow throwers work better with light snow accumulations.Because they’re smaller and less powerful than snow blowers, ATV Snow Throwers are better suited to removing light snow accumulations of about eight to nine inches, maximum. The top of the front intake chute on a snow blower is higher than it is on a snow thrower, so snow blowers can tackle deeper drifts and accumulations of 15 inches or more. In addition, small snow throwers are often not self-propelled, which also makes it more difficult for the operator to physically push them in thicker snow accumulations. The majority of snow blowers on the market today are self-propelled. Equipment for snow and ice removal includes plows, pick-up trucks, skid steers and compact equipment, all-terrain vehicles, front-end loaders, and other pieces of large equipment.Snow Plow manufacturers have made significant advances in the construction and design of plows in recent years. In general, the following plows, combined with proper techniques, will bring greater efficiency to the department’s snow and ice management operations: • Straight plows. Equipment operators using a straight plow should make all passes away from buildings and toward the perimeter. The general rule is to avoid angling the blade toward a building. The goal of Snow Sweeper is to get the snow as far away from buildings as possible. • V-plows. Operators can use a V-plow to make an initial breakthrough. This V-position also is effective for hard-packed snow, ice, and deep drifts. Operators can set the blade in the straight position or angled position for general, wide-path plowing or stacking, and they can use the scoop position for clean-up and carrying snow with minimum spilling.Tiller or cultivator? Gardeners often use the two words as if they mean the same thing, but they are actually different tools. The machines look similar, although tillers are usually larger than cultivators, but each is built to perform a unique function in the garden, and they aren’t really interchangeable. A rototiller, or Tiller, is the heavier and more powerful of the two. Tillers are made for digging deeply and aggressively to break open the soil—for instance, when you’re creating a brand-new garden bed or to getting started at the beginning of the season. Different models offer a range of configurations and functionality, such as rear or front tines, variable depth settings, forward and counter-rotating tine operation, and more. Cultivators, however, are built for finesse. They are made to stir up the already loose soil to incorporate fertilizer, break up crusted soil ahead of irrigation, or assist with weeding. They are compact and lightweight but still powerful, with a smaller working area for greater precision. If you’re not quite sure whether the task at hand requires a cultivator vs. tiller, read on to learn more about these two important gardening machines.

Face masks: what the data say
Описание: Face masks: what the data say When her Danish colleagues first suggested distributing protective cloth face masks to people in Guinea-Bissau to stem the spread of the coronavirus, Christine Benn wasn’t so sure“I said, ‘Yeah, that might be good, but there’s limited data on whether face masks are actually effective,’” says Benn, a global-health researcher at the University of Southern Denmark in Copenhagen, who for decades has co-led public-health campaigns in the West African country, one of the world’s poorest. That was in March. But by July, Benn and her team had worked out how to possibly provide some needed data on masks, and hopefully help people in Guinea-Bissau. They distributed thousands of locally produced cloth face coverings to people as part of a randomized controlled trial that might be the world’s largest test of masks’ effectiveness against the spread of COVID-19. Face masks are the ubiquitous symbol of a pandemic that has sickened 35 million people and killed more than 1 million. In hospitals and other health-care facilities, the use of medical-grade masks clearly cuts down transmission of the SARS-CoV-2 virus. But for the variety of masks in use by the public, the data are messy, disparate and often hastily assembled. Add to that a divisive political discourse that included a US president disparaging their use, just days before being diagnosed with COVID-19 himself. “People looking at the evidence are understanding it differently,” says Baruch Fischhoff, a psychologist at Carnegie Mellon University in Pittsburgh, Pennsylvania, who specializes in public policy. “It’s legitimately confusing.” To be clear, the science supports using masks, with recent studies suggesting that they could save lives in different ways: research shows that they cut down the chances of both transmitting and catching the coronavirus, and some studies hint that masks might reduce the severity of infection if people do contract the disease. But being more definitive about how well they work or when to use them gets complicated. There are many types of mask, worn in a variety of environments. There are questions about people’s willingness to wear them, or wear them properly. Even the question of what kinds of study would provide definitive proof that they work is hard to answer. “How good does the evidence need to be?” asks Fischhoff. “It’s a vital question.”A medical device that is used to inject fluid into, or withdraw fluid from, the body. A medical syringe consists of a needle attached to a hollow cylinder that is fitted with a sliding plunger. The downward movement of the plunger injects fluid; upward movement withdraws fluid. Medical syringes were once made of metal or glass, and required cleaning and sterilization before they could be used again. Now most syringes used in medicine are plastic and disposable. Another low-cost detection system has been designed to detect bleeding, pH and external pressure on the wound, by using a combination of a disposable part and a reusable part attached to a disposable bandage. All the electronics were integrated on a flexible medical tape which can be detached and reused while wireless communication is realized via an inkjet printed antenna. A smartphone can be further used to monitor wound progression regardless of the patient’s location, while healthcare providers will receive this information either via the mobile network or via the internet. An impedimetric flexible sensor based on cupric oxide (CuO) was also reported for pH measurement. CuO is a transition metal oxide that acts as a p-type semiconductor. It is stable, environmentally friendly and enables electron transfer at low potential values. Due to these advantages, CuO was used in the fabrication this sensor. Two configurations were used, CuO nanorods and nanoflowers and the nanorod-based electrodes demonstrated higher sensitivity compared to the nanoflower-based ones. The sensors consisted in screen-printed interdigitated electrodes on flexible substrates. The sensors were tested in a narrower pH range (5–8.5) compared to other techniques, demonstrated certain stability problems and did not include a wireless transmission system. However, their flexible nature makes them promising for future studies regarding the development of portable and wearable systems. The conventional disposable infusion set originally has a protective cover on the needle, which prevents the package and the operator from being punctured and stabbed, and is usually discarded during normal operation. In this project, we transformed such protective cover into a new type one named safety tube. The inner diameter of the safety tube is slightly larger than the outside diameter of the needle body, and the length of the tube is slightly longer than the total length of the needle head plus the needle body. There is a slit along the length from the front to the middle of the tube. The open end (front) of the tube linked with the slit is in the shape of a “V,” the end of the slit at the middle of the tube is linked with a rectangular hole, and the joint is in the shape of an inverted “V.” The safety tube is in register with the needle, and the fin of the needle is out of the rectangular hole. During infusion, the fin is pushed to make the needle slide along the slit out of the tube, and after infusion, the needle slides back into the tube for safety. The safety tube has been commissioned to a qualified manufacturer and applied to the clinical trial. Meanwhile, it was approved by the hospital ethics committee. 200 inpatients who were in need of infusion therapy from October to December 2018 were enrolled and randomly divided into the intervention group and the control group. There was no significant difference in age and disease diagnosis between the two groups ( Researchers in Singapore say they have developed a bandage that can detect and wirelessly send medical information related to chronic wounds, such as temperature and bacteria type. With the ability to capture and transmit such data in under 15 minutes, the wearable sensor is touted to speed up assessment of such wounds and provide more timely treatment. Called VeCare, the platform encompasses a "wound sensing bandage", an electronic chip, and a mobile app through which data is transmitted, said the research team from the Department of Biomedical Engineering and Institute for Health Innovation & Technology (iHealthtech) at National University of Singapore (NUS). The researchers also worked with clinical partners from Singapore General Hospital (SGH). The bandage features a wound contact layer, breathable outer barrier, microfluidic fluid collector, and a flexible immunosensor, NUS said in a statement Thursday. Using an electrochemical system, the hospital bandage detect various biomarkers specific to chronic wounds and facilitate the assessment of the wound's microenvironment, inflammation, and state of infection. The microfluidic wound fluid collector, which is attached to the sensor, directs and enhances fluid delivery to the sensor by up to 180%, according to NUS, adding that this helps ensure the sensor can perform reliably regardless of the ulcer shape or size.The microchip also is embedded with flexible electronics connected to the sensor, enabling data to be transmitted wirelessly to the app for on-site assessment and analysis in real-time. Data is sent to the patient's paired mobile device, on which it is stored and analysed. This processor also is powered by a rechargeable battery. In the study, we used disposable infusion needles with a new type separation-free safety tube for the patients in the intervention group and conventional ones with a self-contained protective cover in the control group. Patients in both groups volunteered to participate and had signed informed consent. Operation Methods Six ward nurses with proficiency in the conventional infusion operation were selected, including 2 nurses working for 1-3 years, 2 for 3-5 years, and 2 for over 5 years. Before the project, all of them were trained in the operation of this new type safety tube and qualified. In the control group, conventional disposable infusion needles were used. After breathing, the self-contained protective cover was discarded, and the needle was fixed after acupuncture, then separated from the infusion set into a sharps box at the end. Patients in the intervention group were treated with new disposable infusion sets. The specific operation steps were as follows: (1) Instead of being removed after breathing, the safety tube slid to the flexible tube when the fin of the needle was pushed along the slit to make the needle out of the tube. Then, the infusion operation was as the same as the control group. (2) After infusion, the needle was removed. The upper end of the flexible tube away from the needle was raised, and the needle side was lowered to make the safety tube slide down to the needle side. Then, the fin was pushed to slide along the slit into the rectangular hole. The needle was thus blocked, and the whole infusion set was disposed into a special collection bag.

Why do People buy Fridge Magnets and How Useful are they?
Описание: Why do People buy Fridge Magnets and How Useful are they? Magnets are one of the most popular souvenirs and among the most commonly used items for advertising and brand recognition.Not only are they extremely useful for sticking important notes and to-do lists on your fridge door, they can also be attached to other metallic surfaces around the home or office. Many people do this with souvenir magnets that serve as a pleasant reminder of their travels and adventures.Some fridge magnets are not only decorative, but practical as well and can come in all sorts of designs such as magnetic bottle openers, notepads, thermometers and many more. What are Magnets made of? There are many different varieties of magnets. Magnets come in all different shapes and sizes and serve various purposes. Some are used as bottle openers or photo frames and due to this magnets tend to be made from all sorts of materials. Magnets that are made of wood often have a rustic feel and this material is generally used for hand-crafted souvenirs from tourist destinations, with place names etched into them. Many souvenir magnets that feature famous landmarks are normally made from resin as they have a surprisingly detailed sculpture of the monument or icon that the magnet is depicting.Magnets produced with a rubber cut design tend to be fun and colourful. These are very popular with the younger generations as they frequently portray comical illustrations of popular buildings or scenes. Plastic or acrylic fridge magnets often display full colour photos and are likely to be given out as cheap and cheerful keepsakes whereas metal fridge magnet designs normally have embossed or engraved designs which have a very high quality feel and make rather prestigious looking gifts. Fridge Magnets of the WorldMany people have a collection of magnets growing on their refrigerator doors without even giving it much thought. Even if you don’t intentionally pick one up every time you go abroad, you will most undoubtedly have had a friend or two who has thought of you during their travels and brought you a magnet back as a nice, little souvenir.Garden ornaments are the items or articles used in the gardens, parks, and landscaping to enhance the beauty and appearance to have a pleasing look. They are made up of weather-resistant materials like stone, concrete, terracotta, ceramic, rustproof alloys and metals, synthetic materials like resins, plastic polymers, etc. Garden ornaments can be broadly classified as follows. 1. Garden plaques: They can be either horizontal or vertical wall plaques. They appear in huge patterns with scripts and carvings to represent history, name, memorial, or certain garden signs. 2. Garden statuary: The statue can be of anything like birds, insects, animals, plants, angels, etc. They are placed depending on the surroundings like the tortoise in the pond, butterfly in a garden, which fits accordingly to give a natural look. 3. Garden fountain: Fountains are the main center of attraction in public parks and gardens. They are decorated with lights of different colors, which gives a must-see look at the nighttime. 4. Garden urns: They are the decorative type of ornaments usually placed on either side of the pathway or at the entrance. They also serve as beautiful planters with an artistic look. 5. Garden obelisks: They are made up of different materials or as living obelisks by cutting and shaping the plant. The plant needs to be pruned periodically to maintain its shape. 6. Garden arches: Similar to the obelisk, they are either living or non-living ornaments. Plants were allowed to grow on arches to give them a pleasant look. 7. Garden ponds and bridges: The inclusion of a water body with cross-over bridges gives a broader look to the parks, which attracts more public, especially children. 8. Garden hanging: Bird's nests, wind chimes, artistic pots, artificial fruits, etc. are some examples that are hanged to decorate the garden. Such types of ornaments can be mostly seen in home gardens. 9. Garden furniture: They serve two purposes in the gardens and parks. You can sit and relax over them and also they add their contribution to the decoration of gardens. We have several garden ornaments, such as metal garden ornament and so on.Many people wonder why wind chimes are often used for feng shui adjustments. Two of the main reasons wind chimes are used are because they create sound energy vibrations and bring in the metal element. First, sound is one way that feng shui practitioners shift the energy of a space. A wind chime can even be used as a space clearing tool to remove negative energy and welcome in new, positive energy. You probably have an intuitive understanding of this; think about how different it feels to be in a silent room, a room with a vacuum going, or the same room with soft music playing. When a wind chime creates sound vibrations, they move through the spaces and objects to shift the energy. Metal wind chimes are especially effective at cutting through any stagnant qi. 9 Tips for a Feng Shui Living Room The second reason is to bring in the metal element. Metal wind chimes are an easy and beautiful way to add the metal element to your space. Metal element represents clarity, efficiency, and joy. If your intention is to call in these metal element qualities, look for a metal wind chime. Metal is also connected to speech and being able to articulate yourself, so a metal wind chime can help activate an intention to speak up for yourself or communicate more clearly. How to Locate Wind Chimes for Feng ShuiWind chimes are especially great additions to the areas of the feng shui bagua map associated with the metal element. These are Dui (completion and children) and Qian (helpful people and travel). Placing a wind chime in either of these areas is auspicious because it activates the metal element associated with these areas. You can also place a wind chime in another bagua area, or gua, where you want to call in metal energy. Or you can simply locate a wind chime in the room that’s associated with the activity. Deciding what garden ornament is right for you and your garden is sometimes more difficult than deciding what plants to buy. Don’t rush your decision. Spend some time working out where you might place an ornament and deciding on what type of ornament would look best. Once you have decided what sort of thing you would like, take your time looking around for exactly what you want. Unless it is exactly what you want, don’t buy the first thing you see. You will regret impulsive buying when you find the “perfect” piece of garden furniture the next week, yet you have already spent your money. Style Choose an ornament that suits the style of your garden. Don’t choose a classical Greek statue if you have a native bush garden. Likewise, a sculpture made from rustic timbers may look out of place in the middle of the lawn in a formal garden. Size and Number An ornament should be a focal point in the garden, drawing the viewer’s eye toward it. Too many different ornaments will look cluttered and detract from one another. However, multiples of the same ornament can make a spectacular statement. Location, location, location When positioning garden art, it’s all about the location. Think about where people are likely to be when they admire your garden art. Consider such things as views from the house; views from seats in the garden, from outdoor living areas or from the entrance to your property. Ornaments or statues should be located where they will enhance such views. Ideal locations are at the end of a vista: perhaps framed by the view through an archway, along a path, or below the canopy of a large tree. Consider the effect of other things in the garden on an ornament. Overhanging branches may enhance, but can also obscure a view. The reflection of a statue on water or in a mirror set behind it can double the impact. A backdrop of dark foliage will contrast with a white statue, but may detract from the effect of a dark coloured statue. Changes in the seasons can also cause changes in the effect created by garden ornaments. Consider what something might look like before and after a deciduous tree has lost its leaves. Statues There are a plethora of statues available, including Nudes, Buddhas, Classical Greek/Roman poses, Fantasy (eg. Gnomes and Gargoyles), Asian, South Seas, etc. They can be large or small; made of stone, ceramic, metal, timber or concrete. You should think carefully about the size and type of statue that is appropriate to your needs. Even the most perfect statue can look inappropriate if it is put into the wrong garden setting. Water Features Garden ornamentation and water often come together in a sculptured pond, wall mounted fountains, bird baths and other water sculptures. With water, the ornament can be given the added attractions of sound and movement.

What is a shopping cart?
Описание: What is a shopping cart? Definition: A shopping cart on an online retailer's site is a piece of software that facilitates the purchase of a product or service. It accepts the customer's payment and organizes the distribution of that information to the merchant, payment processor and other parties. Why shopping carts are importantShopping carts bridge the gap between shopping and buying, so having the best shopping cart software is extremely important on your website.It's likely that those just starting out in the market may be unfamiliar with the concept. Most people, especially those in the ecommerce industry, have likely made a purchase online at some point in their lives. That said, most consumers don't fully realize the need and capability that shopping carts have (besides leading a customer to checkout). A cart typically has three common aspects: It stores product information It's a gateway for order, catalog and customer management It renders product data, categories and site information for user display Another way to look at things is as follows: The online shopping cart is similar to the tangible ones we use at the supermarket, but it wears many more hats. It's also the shelves, the building, the clearance sign, the cash register and often the credit card machine relaying information back to the bank. What options are there? For those seriously considering the ecommerce platform route, it's important to know that there are two basic types of carts: Hosted shopping carts: A third-party firm "hosts" the solution and is responsible for server backups, maintenance and upgrades. The beauty of a hosted solution is that hosting comes free, which means it doesn't cost anything for the third party to keep your site functional on the Web. The main drawback with hosted solutions is that customers will be directed to another domain for payment processing. Licensed shopping carts: This type of solution allows business owners to build their own type of cart and customize it to their specific needs. There is much greater flexibility in changing features and functionality, as well as in adding third-party tools if need be. However, the upfront costs are often higher and require more hands-on expertise for troubleshooting issues and technical support. Hosted solutions are often recommended for those who are beginning their own venture because they require less technical expertise. That's not to say all new online retail store owners aren't adept in IT, but a hosted solution may free up time to focus on other aspects of operations. There are numerous providers of shopping cart software on the market today, and companies must first evaluate their individual needs before making a final decision on which solution is best for them.

USB Powered Adjustable Heat Settings Easy Control Compatible With 28V M-Series Trolley with USB Port Compatible with Motocaddy Power BankShopping Carts are seen in almost every retail store in the United States. Whether you are at a Grocery Store, Clothing Outlet, or a Shopping Center, chances are, you use a shopping cart more often than you realize. Shopping Carts are used and abused daily. Shopping Cart Wheels are exposed to extremely harsh environments from rolling over gravel, hitting curbs, extreme hot and cold elements from being left outside, and even corrosive weather and rain. Due to the repetitive, abusive environments, these wheels and casters can take a beating and tend to wear much faster than most other casters and wheels. Being a large Caster and Wheel manufacturer and wholesale distributor, we've seen many grocery cart repair companies attempt to purchase the cheapest grocery cartwheels to make a quick profit. This is a reason why many grocery cartwheels fail after a short period of time. Quality is the utmost important factor and should always come first over shopping cart casters and wheels. We have seen the frustration when rolling a cart, and the wheel locks up or refuses to roll. This is why Caster Headquarters only sells the highest quality Shopping Cart Casters and Wheels. Our goal is to eliminate the lower-quality grocery cartwheels that have taken over the industry. The leading manufacturer in Shopping Cart casters and Wheels is P&H Casters. We have teamed up with PH Casters to provide the highest quality shopping cart casters in the industry. What separates a P&H Caster shopping cartwheel from the generic brands in the industry is 5 decades or half a century of quality control and testing to make the perfect wheel to endure the harshest environments. These wheels were made to last and perform from the special polyurethane material on the tread combined with dual quad x precision bearings. This wheel is made to outperform any other shopping cart wheel in the industry. When new shopping carts roll out of the production line, a PH Caster and Wheel is typically used until the end of its life expectancy; then, many cart repair companies replace it with an inferior wheel to make the most profit. That is the reason there are so many carts in the industry with bad reputations. CasterHQ and PH Caster's goal is to standardize all Shopping Carts in the USA with the highest quality shopping cart-wheel in the world. The benefits of using our products are superior performance and increased longevity. In return, this encourages shoppers to come back and use your store more frequently because of the ease of mobility and quality offered for every shopper. The smallest details make the biggest differences, especially regarding ergonomics in simple tasks such as pushing a cart. If you have ever been to Target, you should automatically recognize how easy it is to push their carts. You will never run into a problem with the wheels or the performance when rolling their grocery carts. This is due to the P&H Caster wheels that we supply to the Target stores. As you can see, Target has realized early on that quality keeps the customers coming back. Whether providing a clean environment or a grocery cart that is easy to roll, they know quality matters. Some stores where our casters and wheels can be seen include Target, Lowes, Home Depot, Walmart, Kroger, HEB, Kohls, Ross, Macy's, JC Penny, Sams Club, Costco, Ace Hardware, etc. many more big-name retailers. Remember, our casters and wheels are on the new carts. Still, as cart repair companies replace worn-out wheels, they use lower-quality casters and wheels to reduce performance and usability. If you are a shopping cart repair company or an employee replacing the casters and wheels, make sure to use the original, highest-quality shopping cart casters and wheels in the industry. Trust Caster Headquarters when it comes to grocery cartwheels and casters.

Polyimide Film for Harsh Applications
Описание: Polyimide Film for Harsh Applications Dunmore offers coating, metalizing, laminating and perforating services for polyimide film. Dunmore can provide additional functionality through engineering and converting to meet particular physical requirements for mechanical, electrical, temperature and chemical properties not inherent to standard polyimide film. Dunmore is one of the leading converters of polymide film in the world. Polyimide Film Industries and ApplicationsPolyimide film is typically used in industries such as:Aerospace - The Kapton? film is converted and layered together to make multi-layer insulation. Automotive / Industrial - Polyimide films have excellent mechanical, electrical, temperature and chemical resistance making them optimal for demanding industries where performance is critical or harsh exposure conditions exist. Electronics - Polyimide film is the optimalLabeling - Polyimide film, with the right printable coating applied, makes an excellent choice for labels used in harsh environments. Polyimide film is used in applications where reliable, durable performance is required, often in harsh environments. It also can be engineered and converted to meet particular physical requirements for mechanical, electrical, temperature and chemical properties. What is Polyimide Film? Polyimide films are used in applications where reliable, durable performance is required, often in harsh environments. Polyimide film is a lightweight, flexible polymer based material that has excellent heat and chemical resistant properties. Polyimide film can withstand temperatures ranging from -269° C to 400° C. In addition to excellent heat resistance properties, polyimide film also has excellent dielectric properties. Typical applications for polyimide film include multi-layer insulation blankets for space, flexible electronics, tapes, and various other high heat applications. High Temperature Adhesive Polyimide Tape Adhesive Polyimide Tape offers a combination of benefits. It is a high voltage insulation tape made of thin polyimide film. It is coated on one side with a silicone pressure sensitive adhesive which allows it to bond well to most surfaces and materials. The use of a silicone based adhesive is critically important as it allows Polyimide Tape to offer one of its greatest benefits; high temperature resistance. This tape can withstand continuous exposure to temperatures up to 200°C, whilst still maintaining dielectric performance (actual mechanical maximum temperature rating is a little higher). When you combine this high temperature tolerance with its all-round adhesive performance, thin and highly conformable construction, solid polyimide film and economic price, you have a tape that can be used in a variety of areas. Example Applications for Adhesive Polyimide Tape Insulation of coils in electric motors. Fastening heating elements. Insulation for capacitors. Masking for powder coating. Bed surface for 3D printing with ABS. Slot liner insulation. Insulating and fastening flexible PCBs. Magnet wire and cabling. Interlayer insulation in motors and transformers. Some of the many names we’ve heard over the years for this tape is Kapton Tape, adhesive Kapton, sticky Kapton and that sticky brown tape. With the possible exception of that last one, this is understandable but it is not technically correct. Just to be clear, our Adhesive Polyimide Tape is not Kapton Tape. It is an excellent high temperature electrical insulation and masking tape with a range of benefits and we are happy to stand behind it without calling it something it is not. A Transparent Polyimide Film as a Biological Cell Culture Sheet with Microstructures In recent years, the research on stem cell cultures has been actively performed in order to generate cell populations for the functional recovery of human body parts lost by illness or injury. Polymer materials have attracted attention in this field because they have biocompatibility, good mechanical properties, and outstanding moldability. Moreover, polymers are flexible and cheap when compared to glass materials. Polymer materials are often used as cell culture sheets, and polymer substrates with fabricated microstructures have been reported to support the culture of biological cells. Polymer materials in the form of elastomeric gels, porous bodies, films, and particles are suitable substrates for a biomatrix, and can be applied for the culture of complex living systems. In particular, the porous scaffold fabricated on the cells culture substrate promotes cell growth and survival and reproduces the three-dimensional environmental microcosm that is normally present in the living body. These reports show that the cell culture is greatly influenced by the fabricated structure. Moreover, the porous scaffold has to have a structure that is appropriate for the intended purpose; the scaffold system has to have a small surface so that the seeding density of cells is at maximum. Culture systems in which osteoblasts were grown in a straight-line structure made of PI, whose width and depth were 5 μm have been reported. In this report, the substrate material used was PI alone and the fabricated structure was a linear shape. The culture of stromal marrow cells (OP9), interstitial cells generated from bone marrow, has been attracting research attention. This is because stromal marrow cells enhance growth factor production, and support multiplication and specialization of hematopoietic stem and precursor cells. Use of these cells has been applied through tissue engineering to generate blood and bone progenitors. It is anticipated that fabricating fine structures and controlling the growth of different stem cells will allow the generation of sufficient cell populations for use in research or in the clinic setting. To this end, we thought to fabricate and evaluate a fine polymer-based structure in which cells can successfully align and proliferate. Polyimide (PI) has superior heat resistance, mechanical strength, and chemical stability. Therefore, PI is expected to withstand the high temperatures required for the sterilization process. PI-based microstructures have already been shown to be transferable by hot embossing and are therefore suitable for microelectromechanical systems (MEMS) fabrication processes. However, conventional PI is not transparent and has an opaque tan color, which would make it difficult to observe any cells cultured on PI sheets. Therefore, we focused on transparent PI, which recently became commercially available. Compared with the lab-scale preparation, the greatest difference for industrial manufacturing of polyimide films is the stretching process. Stretching process, either uniaxial or biaxial stretching of the gel-like PAA films, will result in the full orientation and extension for the polyimide molecular chains. It shows the main steps of the industrial scale production line of polyimide film by biaxial stretching from PAA precursors. In this procedure, the precursor monomers are firstly introduced into the polymerization reactor containing the solvent. After PAA synthesis, the obtained solution is deaerated and cast in the form of a continuous film onto the surface of a heated rotating stainless steel drum. The solvent is partially evaporated and a part of the imidization reaction takes place simultaneously. Thus, a self-supported PAA film is formed. The gel-like PAA film is peeled from the metal drum and first stretched in the machine direction (MD) while controlling the stretching rate. The PAA film is then stretched in the transverse direction (TD). The solvent is removed by evaporation, and the film is heat treated by means of hot air or radiant heat from an electrical heater to give a biaxial oriented polyimide film. The transverse stretching is carried out at temperatures around 350°C to facilitate the imidization of PAA into polyimide. Such a procedure has been widely used for PI film production, and there has been significant patent activity in the past half century since the commercialization of PI films in 1960s. Up to now, most of the commercially available wholly aromatic PI films have been produced by such kind of procedure.
