Compelling Reasons to Wear Canvas Shopping Bags More Often

Description:     Life in plastic is definitely not fantastic, and we all know that. With plastic shopping bans seeing their banning across the world, the good old canvas shopping bags are coming back bigger, better, and bolder.     Canvas shopping bags and canvas tote bags are not new as fashionable, wearable, and stylish accessories. On the contrary, they become all the rage right now, as they convey an even more powerful statement than luxury designer purses.     They speak not about money but mindfulness, ethics, belonging, access and culture. And the moment you see huge designer houses creating their branded canvas totes or canvas shopping bags, you know you were on the right track all along.     Nevertheless, what makes canvas bags so desirable and so hip these days? We will take a look at modern trends and identify all the compelling reasons for you to wear canvas shopping bags more often – and not only for shopping, of course! >     1. They are versatile     You can easily repurpose a natural cotton shopping bag into a daily casual bag to carry your personal items around town when you are out for a walk, go to the office, or have brunch with your girlfriends.     The beauty of these bags reside in their simplicity. Shop them in bulk in different vibrant colors for your shopping needs and pick the colors that best match your outfits, occasion, or personality. This way you will never run out of stylish and matching purses all year long.     Do you want to know what is even better? Any large and sturdy lunch box bag canvas can successfully replace a beach bag or a gym bag.     2. Size Does Matter     Besides their resilience to weight, large capacity canvas bags come in larger, generous sizes. In other words, they can also host your laptop, DSLR camera, books, school papers, and other work or personal items.     If you want to carry some of your freelancer, student, or working materials around in a fashionable manner, a large, solid canvas shopping bag can take you all places in a fun, eco-friendly, and practical manner. Protecting your items is also easy, as you can opt for some heavy canvas zipper tote bags for extra safety.       3. Mindful Protection of the Environment     One of the greatest advantages of canvas bag shopping is that they are reusable, completely washable, and easy to carry, fold, store, and grab at any time. You do have to wear a canvas tote bag for a while until it returns on its environmental investment, but you can achieve such a goal with no effort.     You can carry your tote bags anywhere you prefer to shop, be it the mall supermarket or the farmers’ market. As long as you wrap some groceries in butcher paper (meats and fresh vegetables that might dirty the canvas bag), you can easily wash the bag and take it to the market next time.     4. Amazing Travelling Bags     If you need an all-nighter bag or a bag that easily transitions from a day bag to a trip bag, you can grab your hand-carried canvas bag and be on your way. While these bags do not offer the comfort of a suitcase or trolley bags, you can use them for short-distance trips, car trips, a weekend at your family’s house trips, and so on.     They can accommodate a pajama, an overnight self-care kit, wallet, phone, headphones, and a book or tablet if you decide to visit friends or family right after work on a Friday evening.     5. Great Travel Accessories     When you travel for longer distances and greater amounts of time – think about a week’s vacation abroad or a city break with your loved one – you can pack one of these plush bags in your luggage. They compensate for all the purses, backpacks, and messenger bags you would think about carrying with you on holidays.     Lighter vacation luggage also means less airport fees and plenty of comfort once you arrive to your destination. They work great in all environments, so you can match one to your jeans-and-sneakers Barcelona walking trip or your seaside kit on a Greek’s island beach.     You can carry them in urban environments, in exotic natural landscapes, in museums, shops, crowded markets, at the restaurant, and during all sightseeing adventures. Besides the fact that they can carry small, big, lightweight or heavy items in the same demure and stylish fashion, you can actually take more than one with you. What is better: filling a suitcase with purses or a suitcase pocket with well-folded canvas book bags in all the colors you love?

Threaded Rod – Everything You Need To Know

Description:     What is threaded rod?     Threaded rod, often referred to as a stud, is a rod of varying length that is threaded in a helical structure.     Similar in appearance to a screw, the threading extends around and along the rod to cause rotational movements when in use. Threaded rods combine linear and rotational movement to create strong resistance to pressure.     The direction of the rotation caused by a full threaded rod depends on whether the rod has a right-hand thread, left-hand thread, or both.     Designed to withstand very high levels of pressure and tension, threaded rods are a common fixing for support systems and used for a variety of applications.     What is a threaded rod used for?     Threaded rods are fasteners and functions thanks to the threading, which causes a tightening action from the rotational movement. Threading on a rod allows other fixings like bolts and nuts to easily screw or fasten to it.     Threaded rods have many applications, effectively working as a pin to fasten or connect two materials together.     Also used to stabilize structures, they can be inserted into various materials like concrete, wood or metal to either temporarily create a steady base during construction or they can be installed permanently.     How to choose the correct threaded rod     There are several types of threaded rod available on the market that will suit different purposes, conditions and materials.     The fully threaded rod that Armafix supplies are usually used when effective grip strength is required through the entire length of the rod.     They are often used to align structures or are embedded into materials, like concrete, as the threading provides good resistance.     The material is another essential factor to consider when choosing the best-suited rod for your application.     Threaded rods are used in a variety of sectors and for several purposes such as construction, plumbing, manufacturing, marine, agricultural, oil extraction and contractor work.     How to cut threaded rod     Sometimes threaded rod will have to be cut to suit your project. It is a common question and not quite as simple as you might think. The rod can be difficult to hold in place and the threading can be affected.     Perhaps the easiest and more efficient way of cutting threaded rod is to use a rod cutter, which will produce a clean, burr-free cut with less effort and less time wasted, plus it is lightweight and can be used for overhead work.     Cutting threaded rod with a hacksaw     If you’re using a hacksaw, a good tip is to take a small block of wood and drill a hole through it to place your rod through.     Secure the rod in the vice with two nuts either side using a thin kerf, the rod can then be cut and held in place. Once it is cut, you can unscrew the nuts, which will tidy up the ends and keep the threading in good shape.     A simple illustration of this can be found here.     Another efficient method is to use a bench vice to hold the rod in place, and an angle grinder to cut the rod. Cut the road at a flat angle and be sure to wait a few minutes before touching the newly cut edge after using an angle grinder as it will be hot.     How to bend threaded rod     As well as cutting threaded rod, sometimes it needs to be bent in order to fit the intended application. This involves using a mounted bench vice and propane or Oxy-Acetylene torch and should be done with caution.     Placing two bolts in the vice again to clamp around the rod, fix the threaded rod securely in place. Apply the lighted torch on the part of the rod you wish to bend.     Metal can be damaged by too much heat, but for stainless steel – as a general rule of thumb – once it is a reddish colour, it is ready to bend. You can reheat the rod several times until you have the required shape.     Remember to use heavy-duty gloves and eye goggles!     How to join threaded rod     If you need to connect threaded rods, you can use connector bolts to get the required length and secure them together.     You can also use threaded rod plastic protection caps to cover and protect the ends.     The welded washers are usually there for shear (tension wouldn't require the weld EDIT: IT WOULD REQUIRE THE WASHER, THOUGH). If you have adequate friction resistance or shear keys under the baseplate, you don't need welded washers. If you designed the connection to resist lateral loads through shear in the bolts, it depends. If you designed for 2 of the 6 bolts (I'm guessing at your layout) to take all of the shears, you probably don't need the welded washers as long as your ok with movement of the base of the column equal to the diameter of the oversized hole (again, assuming it's oversized) minus the anchor diameter (Not half, but all - what if the anchor is slightly off and hard against the opposite side of the hole? There's a reason oversized holes are used in baseplates.) If you need all of the bolts to resist the shear, then you need to have welded washers at all of the bolts. If you don't, you could have a couple bolts closer to the sides of the holes than others, so they'll load first and prevent the others from loading until they have deflected and/or failed - and then the others engage with two fewer than needed and the rest fail.

The Basics of Tie-Down Straps

Description:     A tie down strap is a length of webbing that is tensioned and used to secure cargo or equipment for transportation. They are available in lengths ranging from around six feet for small loads to 40 feet for commercial trucking applications and typically range from one inch to four inches wide. Tie-down straps come with two ratings to indicate overall strength; break strength describes the maximum comfortable weight that can be supported before the strap fails, and working load describes the maximum weight that a tie-down can support with regular day-to-day use without becoming damaged. The working load is generally calculated as one-third of the break strength.     Towing Ropes     Towing ropes feature an easy-to-use gator clip, and are generally the lightest-duty tie-down strap with a maximum of 100-lb working load and 220-lb break strength. They are designed for use on cargo carriers, game carts, and other small loads.     Cam Buckle Straps     Cam Buckle Straps are generally lighter-duty than ratchet straps but heavier-duty than lashing straps. They are designed for use with medium-sized loads such as dirt bikes and ATVs, and can have up to a 500-lb working load and 1,500-lb breaking strength. They are easy and quicker to tighten and release than a ratchet strap, but cannot safely secure as much weight.     Ratchet Straps     Ratchet tie down straps are named for their method of locking and securing the strap via an easy-to-use ratcheting system. Ratchet straps can have a working load limit up to 5,000 lbs. with a 15,000-lb break strength rating and can create a tighter and more secure restraint – ideal for solid, heavy loads.      Bungee Cords, also known as shock cords, are better suited to light-duty applications such as hanging a tarp or tying up small items for storage.     If you're like us, you're probably using your garage for anything but a place to park your ride. And that's because it's become a warehouse for all of the stuff you can't find room for in or around your home, like toys, cleaning supplies, gardening equipment, and tools. Getting the space clean and orderly has probably been on your to-do list for ages, which is why we searched far and wide for the best garage storage ideas. Whether you're looking to give the area a whole top-to-bottom makeover, or just want a convenient, tidy method to sock away your family's bikes, we have what you need.     One of the best ways to organize your garage is by grouping gear of the same kind together so it's easy to find. Using a combination of shelves and storage hooks, this gardening equipment is stored neatly side-by-side, with a large, labeled bin for holding smaller items.     Kick clutter to the curb with a sturdy slat wall hooks and panel that uses baskets, and more to hold necessities like cleaning and gardening supplies.     For a indoor place to hang your go-to jacket or everyday bag, consider a wall-mounted coat rack or hooks. We have plenty of recommendations in our guides to coat hooks, which are sturdy, take little space, and add a pop of style.

Whole Herbs vs. Standardized Herbal Extracts: Which is Better?

Description:     Many Herbal Products to Choose From     The mainstream use of herbal medicines is becoming increasingly popular, and there are many herbal products to choose from. With so many choices, it is easy to get confused about which forms of herbs are right for you. One important decision is whether to use whole herbs or standardized herbal extracts. This can be tricky because even the experts are split on this issue. Therefore, it is best to know the facts about the difference between the two so that you can make an informed decision.     Whole Herbs     A whole herb is just what it says: the whole herb, usually dried and encapsulated or processed and preserved in alcohol or another solvent. Whole herbs contain all of the constituents of the plant and have been used for hundreds of years by many cultures. In fact, modern medicine originated with the use of whole herbs. The medicinal properties of herbs have been learned through empirical observation and the information has been passed down through successive generations of healers. Although the effects of herbs have not always been formally and scientifically researched, whole herbs have a long track record validating their safety and efficacy.     The chemical makeup of an herb can vary slightly, however, depending on a variety of factors. First, the environment in which the plant has been grown has an effect on the constituents of the herb. The time of year it is harvested, the soil in which it is grown, and the weather all influence the overall quality of the final product. Second, methodology plays a role. For example, the age of the plant at harvest, the exact part of the plant being used, and processing techniques can all make a difference. Finally, each plant or population of plants has its own individual genetics, thus adding another source of end-product variation.     Standardized Herbal Extract     Standardized herbal extracts are functional ingredients that have one or more components present in a specific, guaranteed amount, usually expressed as a percentage. The intention behind the standardization of herbs is to guarantee that the consumer is getting a product in which the chemistry is consistent from batch to batch. This practice has developed out of the drug model of herbal medicine, in which modern scientists have attempted to identify the components of a plant that have definite pharmacological activity in the body. Unfortunately, while scientists can isolate many constituents from an herb and discover how particular chemicals may act in the body, they inadvertently remove or overlook components that may contribute to the activity of the whole herb. Consequently, standardization may concentrate one constituent at the expense of other potentially important ones, while changing the natural balance of the herb’s components.     As more shoppers gravitate toward fresh foods in lieu of processed items, bakers must examine how their products align with this changing attitude. According to the U.S. Department of Agriculture, Americans are consuming more products than ever, but the average U.S. diet still falls short of the recommendations listed in the 2015-2020 Dietary Guidelines for Americans due to lack of access, busy schedules, poor eating habits and more.     While nothing may ever completely replace the feeling of biting into a crisp apple or the smug satisfaction of finishing a salad, fruit and vegetable powders give snack producers an opportunity to provide consumers with nutrient-dense products that can be conveniently enjoyed without the intense prep work other fresh items require.     ON THE FACE OR body, a dusting of powder gives a smooth finish to the skin, covers blemishes and flaws, and absorbs perspiration and excess skin oil.     The marketplace offers a profusion of powders. There are matte face powders, in loose or pressed form, that are designed for dry, normal or oily skin; translucent powders that allow the natural skin color to show through; opalescent powders that give the skin a slight shimmer; tinted powders that tone down ruddiness; body powders that are suffused with fragrance or with glitter for nighttime sparkle; baby powders that are made from either talc or cornstarch; medicated powders that fight body odor and troublesome microorganisms or soothe irritations, and even perfumed liquid body ''coolers'' - powder suspended in an alcohol base - that dry on the skin to a powder finish.     The highly purified powders of the present are a far cry from the crude cosmetics of the past. From the dawn of history, vanity led women to sometimes life-threatening lengths to whiten their skin. The earliest powders were concocted from ingredients such as bean flour, chalk and ceruse, a highly toxic white lead.      Today, most powders are a blend of several cosmetics ingredients, including talc, zinc oxide, titanium dioxide, kaolin and magnesium carbonate, each of which imparts specific benefits. According to cosmetic chemists, the ideal powders should have five characteristics: covering power, absorbency, adhesiveness, slip and bloom.     There’s a lot of buzz around probiotics. They’re endorsed by celebrities and fill grocery stores aisles.     Probiotic powder is beneficial bacteria that promote a healthy gut. Scientists believe they could unlock a deeper understanding of our health. Probiotics are found in some foods and drinks, like yogurt or fermented tea.      Just like vitamins, probiotics are available as supplements. Manufacturers make steep claims about their benefits. They include digestive health, strengthened immune system, weight loss and reduced cancer risk.

Reducing the risk of wound infections with disposable surgical clothing

Description:     To minimize the risk of germ transfer in surgical operating theatres, sterile draping of patients, their surroundings and the wearing of sterile clothing are all essential safety measures, irrespective of the nature of the operation. Given their vital role in infection protection, draping materials and operating theatre clothing are legally regarded as medical products with their production and quality testing subject to European Standard EN 13795.     Reducing the risk of wound infections with disposable surgical clothing     Different operations have different risks of infection. Long, complex operations involving high levels of blood and irrigating fluids, carry the highest risk while risk is lower, but still present, in shorter operations where large amounts of body fluids are not expected. Even with careful observance of hygiene standards, and execution of the usual antibiotic prophylaxis, there is infection at the surgical site in approx. 1-5 % of elective surgical procedures. For the patients affected, this means an extension of their pain and functional restrictions – even if there are no more serious consequences.     Single use vs. Reusable Materials     The material used in surgical drapes and sterile clothing also raises issues of health economics. Draping materials and operating theatre clothing made of nonwoven fabric are often preferred to reusable textile systems due to the material safety and the associated high level of protection against infection. Although these are the most important reasons, another benefit is that single-use materials remove the need for sophisticated reprocessing of reusable textile systems, which is a cost-intensive undertaking.     Medical products are classified into two performance levels: high performance and standard performance. This means that draping materials and 68g original-spunlace nonwoven surgical gowns can be tailored exactly to the respective surgery-specific requirements in material quality and product design. This flexibility allows hospitals to choose safe, cost-effective standard performance speciality medical drapes for low-risk operations and specific tailored surgical gowns for higher-risk operations involving large amounts of body fluids.     Single-use and reusable products are subject to the same safety standards as applied to reusable products for their entire life cycle.      The minor procedure sets contain a large assortment of instruments. All tools are manufactured of high-quality nonwoven and are contained in a durable canvas case.

ROLE OF ANILOX ROLLER IN FLEXO PRINTING

Description:     The ceramic anilox roller is often referred to as the heart of the flexographic press. It is designed to deliver a precise and consistent amount of ink to the printing plate.      An anilox roll is a hard cylinder, usually constructed of a steel or aluminum core which is coated by an industrial ceramic whose surface contains millions of very fine dimples, known as cells. The choice of the correct anilox roller is of central importance for an optimal printing result. Depending on the printing type, we recommend different engravings and cell volumes. The choice of the correct anilox roller is of central importance for an optimal printing result.     A flexographic printer often faces problems due to the nonavailability of the correct anilox roller. The purpose of this article is to make an attempt to throw some light on this very important subject.     Anilox roll:     The flexo printing/coating process depends upon the precise controlled transfer of a liquid ink, varnish or coating. An anilox roll is simply a metering roll designed to consistently supply a uniform and measurable volume of ink onto the image carrier.Anilox roll is considered to be the heart of the flexographic press. Older methods of mechanically engraving cells in to the surface of a roll have been replaced, to a large extent, by the precise computer controlled laser engravings of ceramic coated steel rolls. In this process, millions of minute holes (cells) are drilled into the ceramic surface of the roll. Ink receptivity and releasing capabilities of the anilox roll is of higher importance and ink transfer capabilities of the plate are determined by the surface technology of plate, surface tension of plate & ink and plate to ink compatibility.     The central part of the press is the anilox roller, the ink metering system unique to this process that allows the correct amount of ink to be carried to the printing plate. On the surface of the anilox roll are etched the cells which act as ink carriers.     The latest chrome anilox roller is laser engraved, with cell counts currently up to 500 cells/cm, from a steel roller and coated in fine ceramic. These laser engraved ceramic rolls could last up to 10 years, depending on the wear they are exposed to from contact with the doctor's blade. They provide an even, and consistent ink delivery in a controlled manner and provide narrow web flexo with a competitive edge in the leading packaging markets eg self-adhesive labels for wines. Once the anilox is ‘charged’ with ink, the excess is wiped off with a flexible steel doctor blade.     Besides the cell geometry, ink release capabilities of the cell are also affected by rheological properties of ink like; viscosity, surface tension, printing pressure between the plate cylinder and the impression cylinder, substrate properties, etc.     Anilox engraving angles:     Available engraving angles for anilox rolls are as follows; 90 degree angle, 45 degree angle, 30 degree angle and 60 degree angle.     In 60 degree anilox angle, the hexagonal cell offers 15 per cent more cells on the same area. Higher quantity of cells indicates a plus point concerning the ink transfer, as well as homogeneity.     Anilox sleeves:     Some of today's servo driven narrow web presses make use of anilox sleeves, which are much lighter than the standard solid anilox. The advantage is ease of handling and loading. On the narrow web side there is no difference in performance than with a conventional roll. Ceramic anilox sleeves initially were profiled in a scenario of short-run environments where anilox changes are very common and required, but have shown their usefulness regardless of the frequency of changeover. Sleeves are easier to store and inventory.     The disadvantages of sleeves are their cost as well as the different care and handling that is required. Converters need to design special racks to store sleeves so that the chance of damage is minimized. In addition, sleeves cannot be cleaned in the same fashion as rolls, which may add more time and cost.     Mirror rollers are generally used in plastics, packaging, printing, steel and other industries. Since traditional hard chrome electroplating cannot fully meet the requirements of wear resistance and corrosion resistance, our matting rollers can perfectly solve these problems. Its hardness is increased from HRV800 with hard chrome layer to HRV1200, the corrosion resistance is greatly improved, and the service life is long.     Dr blade materials, on the other hand, are a little more complicated of a subject than that of their shape. There are five materials commonly used to create blades today and they are as follows: plastic (UHMW/UHMWPE), stainless steel, carbon steel, tool steel and graphite. While the steel blades have upsides and are favored by many within the industry, current trends and advancements in technology are heating up the playing field for plastic and graphite.

How To Make a No-sew Wristlet Key Fob

Description:     What is a wristlet key fob?      Ever had so much character ribbon or just decorative ribbon lying around and wonder what else you could do with it besides making bows?  Well, wristlet key fobs are the perfect way to put that ribbon to use. You can make something fun and creative that you can give out as gifts for family and friends, while only spending a few dollars for all the supplies. Key Fobs are awesome wristlet keychains that you can use to keep track of your keys. They can be simple or as decorative as you like.      The devil is in the details when it comes to personal style. That’s why your everyday carry – wallet, pocket knife, etc. – is so important. Elegant details in the form of a dialed-in EDC collection makes a big impact style-wise when going about your day. If you’re looking to upgrade your EDC, we’ve got an easy recommendation: the best leather keychains.     Keychains are often overlooked, but they’re actually quite useful for keeping your keys organized and keeping your look on-point. In other words, the best leather keychains are like little style easter eggs that streamline your pockets. But top-notch keychains can be hard to find, so we rounded up seven of our favorites below.     Although we’re all familiar with keychains, there’s actually a decent variety to choose from. Here are a few things to think about while shopping for the best leather keychain.     We’ve rounded up three kinds of keychains: key fobs, wrist lanyards and key organizers. Key fobs are a sturdy keyring with a decorative leather attachment. Key wrist straps or wrist lanyards are often less stylish than fobs, but up the convenience by allowing you to dangle keys from your wrist while, say, unloading the car. Organizers are very handy, securing keys in a leather pouch.     The best acrylic keychains are begging to be flashed when handed over to the valet. It’s a fun way to upgrade your everyday look, so go with something that speaks to your personal style.     Always be sure to check the dimensions of a keychain – especially if you keep your keys in a pocket.     Sneaker keychains come in very handy when unloading groceries, unlocking multiple doors and simply keeping track of your keys. We like this one from Feelcase because it’s made from a single piece of full-grain leather that feels nice in your palm or on your wrist. You’ve also got 11 leather/claw color combos to choose from, so there should be something for every personal look. It is slightly on the large side, however, at eight inches long.     The wristlet wallet is an amazing idea that fits perfectly into the concept of creative design and functionality. It is not only an elegant accessory, it is a piece that offers much comfort for those who do not want to leave with a bag. Bags are often a nuisance, especially at concerts and clubs because restrain the freedom of movement. In this way, the wristlet handbag was to create a discrete accessory that can be used as a necklace or bracelet. The difference is a small detail, the piece bringing together a wallet built to keep money, documents and cards. Depending on the model, the accessory has closure with buttons, velcro or zipper.

Must-Haves in Long-Lasting Milling Tools

Description:     During the last few decades, dental supply manufacturers from all over the world have introduced many different types of dental raw materials. Some did well initially but eventually faded, some never saw the light of day, and some skyrocketed, specifically zirconia. Today, all things considered, zirconia is the best material for dental restorations.     What Is Zirconia?     Zirconia consists of zirconium dioxide, which has the highest mechanical strength and fracture resistance of all non-metallic materials. Besides the strength, the other main reason it is widely favored in medical devices is due to its superior surface smoothness. In addition to medical prosthetics, zirconia has been widely used across industry and markets in such products as watches, knives, jewelry, valves, gears, and pumps, to name a few.           Zirconia in Dentistry Today     Zirconia is the most recent arrival in dental materials. It only became popular when CAD/CAM was introduced in the dental laboratory process in the 2000s. Until about 2009, when gold prices soared, zirconia had only a small share of the market in dentistry. Then, as an alternative to expensive gold crowns, dental zirconia ceramic became a more popular choice among restorative dentists.     If multilayer?zirconia is the best material, then why wasn’t it used much before? It’s simple. Most mom-and-pop local dental labs could not afford to invest in high-tech, computerized, advanced CAD/CAM systems. Additionally, most of those small labs did not have the skill or knowledge to use the new technology.           Three Popular Variations     Most zirconia in the market today shares a very similar composition. However, the manufacturing process differs slightly depending on the purpose of the zirconia. For example:     Solid or monolithic zirconia with full compressed blanks to get the maximum strength (1,100 to 1,200 MPa)     Lightly compressed zirconia to accommodate medium translucency of anterior restorations (700 to 850 MPa)     Full zirconia framework stacked with zirconia powder (layered zirconia) to accommodate maximum aesthetics for anterior translucency           There are many different types of zirconia for dentistry today, and it’s confusing because of the many brand names. I receive many calls from our clients asking about this brand and that brand, but my answer is always the same.     Regardless of what they call it, most zirconia shares a similar composition. However, it differs according to the manufacturing process, which affects two main characteristics: strength and translucency (or opacity).     For example, the opacity of the dental zirconia blank is directly proportional to the strength. In other words, the strongest zirconia blanks are the most opaque they will be. Therefore, if you need the highest translucency (the least opaque blank) for your anterior restorations, the strength is significantly compromised. Still, it may be stronger than other non-metallic dental raw materials.           Why Dental Zirconia Is the Best Material     There are three reasons why zirconia is the best material for dental restorations, primarily based on a comparison of metal-containing products, such as porcelain fused to metal, a full metal crown, and titanium. By comparison, zirconia is much more aesthetic, lasts longer, and is even more biocompatible. However, there are a few downsides as well.           Unless you are closely involved with the dental sector, you may not know that acrylic polymers (PMMA or Poly Methyl Methacrylate) are essential in creating the very highest quality, lasting solutions for dental procedures.     Statistics show that there are huge percentages of the population in Europe and the Americas with missing teeth and affected with oral disease. According to the WHO, (World Health Organization), around 30% of the population aged 65-74 has lost their natural teeth while 60-90% of school children worldwide have dental cavities. Add to these factors an increasing consumer awareness of oral health issues and a rapidly increasing population and it is clear that there is much evidence to suggest that the global dental products market is set to grow significantly.     For over 65 years we have been working closely with global market leaders and academic communities to build on our knowledge in the dental sector to develop leading edge dental PMMA.     If you have braces you may find that they rub against the insides of your cheeks or lips. Sore spots on the inside of your mouth can develop because of this, especially in the first days and weeks of you wearing braces. The best way to treat this is simply by applying a little dental wax to your braces. The wax helps to make a barrier between your braces and your lips, cheeks, tongue and gums. The wax is easy to apply and will most likely have been supplied to you by your orthodontist.     In the past several years, the use of zirconia restorations has become increasingly common. Due to the increasing number of prescriptions for zirconia restorations, more laboratories are purchasing milling machines to mill the copings and crowns in-house. After learning how to use the mill, most dental laboratories seek to increase and maximize productivity with the milling machine. To help with this goal, laboratories need to consider three aspects: the use of the right materials, proper nesting, and tooling. This article focuses on the third aspect—milling tools and three features that add value.     The second aspect is the coating. When milling zirconia, using diamond-coated tools will significantly extend the life of the milling burs. We manufacture all our milling burs with the highest-quality materials. The diamond coating that Primotec uses is a proprietary chemical diamond formula, making the tools last up to 10 times longer than standard carbide burs. Finding high-quality zirconia that is not too hard in its pre-sintered stage will also help increase bur life drastically.     The flutes are the third aspect. Most milling tools on the market use only two flutes. Our burs use three flutes, which means 50% more cutting surface than those with two flutes. This point alone can add as much as 50% more life. Also, we notice that the milled restorations are even smoother than those produced with only two fluted tools. If you want to increase your feed rate, that additional flute helps in removing the material at a quicker rate, maintaining a quality surface finish.

The Global History of the Bandana

Description:     Long before American cowboys sported bandanas, the European snuff user of the 18th century suffered from an embarrassing problem: Blowing his nose into a white or solid-colored handkerchief left behind dark tobacco stains. He found a stylish solution in India, where textile makers employed a millennium-old tie-dyeing technique called bandhani to create colorful silk and cotton kerchiefs covered in lively patterns. After the Dutch and English East India companies imported these kerchiefs to England, snuff-takers embraced them to make their habit more discreet, and the name was anglicized to “bandana.”     By the early 19th century, Europe had started producing its own face bandanas, most notably in Mulhouse, France, where dye producers developed a version of Turkey red, the color most commonly associated with bandanas today. The original dye was made of sheep dung, madder root and olive oil, and applied to fabric through a process so complicated it inspired “all sorts of industrial espionage,” says Susan Brown, associate curator of textiles at the Cooper Hewitt Smithsonian Design Museum. The familiar paisley pattern imitated Kashmir shawls.             In colonial America, tube bandanas were sometimes printed with maps, as guides for travel. They also made a splash during the Revolutionary War. One bandana from the period featured a likeness of George Washington astride a horse, encircled by a series of cannons and the words, “George Washington, Esq., Foundator and Protector of America’s Liberty and Independency.” Historians suspect that Martha Washington commissioned this cotton headband, likely made in 1775 or 1776 by Philadelphia textile manufacturer John Hewson.         Bandanas have appeared frequently in American politics ever since. Theodore Roosevelt’s 1912 bandana included the words and music for his boisterous campaign song, “We Want Teddy.” The bandana for Adlai Stevenson’s 1956 presidential campaign featured a smiling photo of the candidate and exhorted voters to go “All the Way with Adlai.”     Still, beloved by cowboys and bandits—including a bank robber in Miami Lakes, Florida, this January—bandanas today are used as a handkerchief, neck gaiters, headwear or, in Covid-19 times, face mask. “They were largely meant for hard use,” says Madelyn Shaw, a curator at the Smithsonian National Museum of American History’s division of cultural and community life. Despite their all-American status, the best-selling bandanas during the pandemic aren’t red, white or blue. They’re black.         Few accessories have lived as complicated a life as the headscarf. The versatile fabric has been chosen by and impressed upon people for political, religious and practical purposes for centuries. It has been favored by revolutionaries and royalty alike. It can be either conservative or rebellious. Beyond its utilitarian origins as a source of protection from the elements, the headscarf remains at the center of contentious debate about women's rights, identity, power and class.     Throughout history, the cotton bandana has sat atop the heads of culture defining women -- and men -- from monarchs including Queen Victoria and Queen Elizabeth II to the daring flappers of the 1920s. Ranging from patterned prints to luxe fabrics to simple sheaths, the fashion item is wrapped in centuries of interpretation.     "There's a reason why the (head)scarf has transcended time," said Lynn Roberts, vice president of advertising and public relations at fashion outfitter Echo Design Group, over the phone from New York City. "When you're wearing one, people pay attention."

THE BEST FOOD DEHYDRATORS ON THE MARKET TODAY

Description:     You can purchase food dehydrators that are reasonably priced and make your own dehydrated grub. These drying machines are usually very simple to use and they’re a great way to store your summer surplus. It really is fun to buy the freshest plums, apricots, grapes, apples and bananas to make your own healthy snacks.     HOW THEY WORK     Microwave Dryers are usually small-sized appliances that are perfect for drying fruits, vegetables, seeds, herbs, fish and meats.     If you grow your own fresh vegetables or have produced fruit trees, grapevines or berry bushes, you would probably really appreciate being able to put some up without using up valuable freezer space (or having to dig it out – especially from a chest type).     Or you can go through the more labor-intensive process of canning it which, in the case of fruit, generally adds more sugar to the end product.     For those that do not have the luxury of owning your own garden, you can take advantage of seasonal offerings by shopping the sales in the produce market and benefiting from reduced prices.     Simple to use dehydrators come in many sizes with varying numbers of shelves or trays for drying.     You place the food on a tray and the appliance slowly distributes heated air throughout the mesh-covered trays.     The hot air dryer generates a very gentle heat (at least the good ones) that dries the food at a slow and even rate, preserving the organic matter and preventing “case hardening” on the outside.     Case hardening occurs when the fruits, vegetables, or meats are heated too fast, forming a seal on the outside and trapping in moisture. It is very important to remove as much water as possible in the drying process.     Each dehydrator will work a little bit differently and the rate at which foods can be dried will vary accordingly. For example, thicker, denser foods will take longer to dry compared to something like soft fruit, which breaks down more easily. As you begin to work with a new machine, you will come to learn the appropriate sizes to cut different fruits, meats and vegetables to obtain the most efficient drying process.     Roasted vegetables are a uniquely special side. They're tender and creamy but crisp and crunchy. The long, high-heat roast also gives them a delicate bit of char or caramelization that's delicious and almost impossible to repeat with any other cooking technique. Our roasting machine can meet your requirements very well.     The fruit and vegetable equipment imitates the manual washing method and adopts a mesh belt drive. The high-pressure air pump generates gas, which makes the fruits and vegetables perform a powerful rotary motion in the washing machine. Under the action of high-pressure water flow and strong bubbles, the impurities on the surface of fruits and vegetables are effectively separated. At the same time, because the material rotates in the steam-water mixture, it effectively avoids damage to the material such as bumps, bumps, and scratches during the cleaning process.     As a company specializing in the production of food fruit and vegetable processing line, we have observed the growing demand for such products in the market. Especially in China, sales of processed juices continue to increase in recent years. In developed countries, this processed fruit beverage has commanded nearly 50% of the beverage market, but in China, it’s only 20%-30%. Therefore, we believe the China market still has a huge potential, and will further develop in the next few years.
