HDPE pipe is a flexible plastic pipe made of thermoplastic high-density polyethylene widely used for low-temperature fluid and gas transfer. In recent times, HDPE pipes got their extensive uses for carrying potable water, hazardous wastes, various gases, slurry, firewater, stormwater, etc. The strong molecular bond of HDPE pipe materials helps it to use for high-pressure pipelines. Polyethylene pipes have a long and distinguished service history for the gas, oil, mining, water, and other industries. Due to its low weight and high corrosion resistance, the HDPE pipe industry is growing tremendously. In the year 1953, Karl Ziegler and Erhard Holzkamp discovered high-density polyethene (HDPE). HDPE pipes can work satisfactorily in a wide temperature range of -2200 F to +1800 F. However, the use of HDPE Pipes is not suggested when the fluid temperature exceeds 1220 F (500 C).

The worst time to figure out that you hate a new sofa is after it’s been delivered. The convenience of online shopping makes browsing easier, but when you’re buying a couch sight unseen, it’s important to do your homework. After hundreds of hours of research, including visiting three furniture factories, interviewing industry experts, and parking ourselves on nearly every sofa we’ve seen, we can tell you exactly what separates a great sofa from a future curbside donation. This guide will walk you through everything you need to know to bring home a durable—and comfortable—piece of furniture. And we recommend some worthy brands we’ve personally tested.
Finding the right sofas for your space and budget begins with deciding what type and style you want. Just as important, you’ll need to determine what size sofa will fit in your home(including through doorways, down hallways, and up stairs, among other exterior and interior obstructions). Then consider how many people you want to seat and what you should avoid (and invest in) if pets or kids will regularly use the sofa. We tell you how to check for quality construction, how much you should expect to spend, and when you can get the best deals. We’ve also put together a buying checklist that you can consult while you’re shopping to help you remember the most important details.
Although a designer may take offense if you call their sofa a couch, or lounge chairs, in everyday use there’s no difference. Both describe a cushioned piece of furniture with a back intended to seat more than one person. “Sofa” has always implied a more formal seating arrangement for entertaining guests (and the design/retail industry favors the term), and “couch” connotes the relaxed comforts of seating that’s intended to welcome any and all.
Choose a sofa styleChaise: Imagine the seat of upholstered chairs and stools stretched out and you have the chaise. Traditionally this sofa features one side with an arm and the other side without (aka a méridienne sofa or fainting couch), like benchs, but many chaise designs forgo arms altogether.
Be honest with yourself about how you’ll sit on the sofa. In retail stores, we’ve seen shoppers sitting on sofas with tables like they’re upright mannequins, which is likely not the way they would sit or lie on them at home. If you tend to slouch, a daybed or sectional with a chaise will prove more comfortable and won’t disfigure cushions (over time, slouching presses the front of seat cushions outward). If you’re a couch napper, avoid multi-cushion sofas, because they’re prone to buckle and dip between each cushion. If you prefer to sit upright while reading, knitting, or using a mobile device, the more tailored, firmer structure of a mid-century-modern–style sofa or one with an upright back will feel more comfortable.
How many people will sit on the sofa?
Think through how many people will regularly sit on the sofa, but also how they like to sit. For example, if one person likes to sit upright but the other likes to lie across with their head on an arm, and the choices ate single sofas, or two seater sofas, that’s how they should test out a sofa for comfortable width. Larger families or households that regularly host guests will be naturally drawn to sectionals. But to produce a more dynamic and flexible seating arrangement, also consider using two different-size sofas positioned into an L shape, or try a pair of loveseats facing each other.
Do you have kids or pets?If you have delicate wood floors, carefully consider the legs of your sofa, or console tables. From experience, we know that hairpin legs can scrape wood floors. As a last resort, a well-placed area rug can keep sofa feet from damaging a floor.

The first thing you should know about e-bikes is that they’re here to stay. Electric bike sales jumped by an incredible 145 percent from 2019 to 2020 alone, according to the market research firm NPD Group. It’s a nearly $244 billion industry as of last year, and there’s no sign of a slowdown.
Some view the rise of e-bikes as a threat, as though standard bikes will go the way of the penny-farthing once everyone goes electric. But fear not: E-bikes aren’t here to rob us of our human-powered way of life. In fact, they may very well enhance it—especially as travel and commuting habits change following the global pandemic and shift of work commuting. So as we roll our way into peak riding season, here’s everything you need to know about the electric revolution.
1. E-bikes make pedaling easier.
Generally speaking, e-bikes are electric bicycles with a battery-powered “assist” that comes via pedaling and, in some cases, a throttle. When you push the pedals on a pedal-assist e-bike, a small motor engages and gives you a boost, so you can zip up hills and cruise over tough terrain without gassing yourself. Called “pedelecs,” they feel just like conventional bikes—but better, says Ed Benjamin, senior managing director at the consulting firm eCycleElectric. “You control your speed with your feet, like with a regular bike,” he says. “You just feel really powerful and accelerate easily.”
3. You’ll ride a lot more, even if you already ride a lot.
Getting an e-bike can dramatically increase how often you ride, according to a survey of nearly 1,800 e-bike owners in North America. Beforehand, 55 percent of respondents said they rode daily or weekly. After buying an e-bike, that number soared to 91 percent. It makes sense: Even if you’re super fit, you still get tired (likely from training or racing) and remounting your bike can feel like a chore. If you have an e-bike, you can continue riding while giving your knackered legs a bit of a break. You can also go faster, which makes biking for longer trips more attractive, even when you’re pressed for time.
For those who aren’t frequent riders, e-bikes open up a whole new world, like fat tire electric bike. While you may not be conditioned to ride 5-10 miles at a time, you can cover those distances easily with an electric assist, which is a great way to build endurance and confidence. That same survey found that 94 percent of non-cyclists rode daily or weekly after getting an electric city bike.
4. There’s an e-bike for everything.
Name a type of riding, and there’s an e-bike for that. If you have zero interest in an electric road bike, you may find yourself head over heels for a high-capacity e-cargo bike that can haul 400 pounds of stuff while still cruising at a cool 15 mph. E-bikes are available in fat, cargo, commuter, recreational, hardtail, full-suspension electric mountain bike, and even performance road bike styles. For proof, here are a dozen e-bikes we love for every type of cyclist.Consider, too, that more than half of all driving trips are shorter than 10 miles, with some surveys reporting that the average single trip amounts to just 5.95 miles. That’s a no-brainer distance to cover by e-bike. In fact, the survey found that owners replaced 46 percent of their car commutes and 30 percent of their driving errands with electric road bike rides. All you need is a great commuter bag to carry your stuff, and you’re set.E-bikes, including electric folding bike, do some of the work for you, but they still count as exercise, especially for people who have otherwise been sedentary. Colorado University researchers found that when 20 non-exercising men and women e-biked about 40 minutes three days a week, they improved their cardiovascular fitness and blood sugar in just one month. “Many people are not fit enough to ride long enough to get meaningful health and fitness benefits from biking,” Benjamin says. “Put them on an electric bike and they can go out and ride for an hour and get a significant amount of exercise.”
8. Trail access can be tricky.
E-bikes remain a subject of controversy in mountain biking circles, some think it more is electric scooter, or a citycoco, and inside the city, we can also see electric wheelchairs. You may not be able to take one on your favorite singletrack right now, as most non-motorized trails prohibit them. However, things have been tilting in a more permissive direction. IMBA, the sport’s largest public advocacy group, shifted its stance to support allowing access for some pedal-assist e-bikes (those that top out at 20 mph) on some trails. With every major manufacturer making e-mountain bikes, more access is likely only a matter of time. “In a few years, people will realize that electric mountain bikes have no more trail impact than a regular mountain bike,” Benjamin says.

The use of artificial grass to replace natural grass is becoming increasingly predominant in today’s world. Especially in sports, different sports pitches use one of the many different types of artificial grass because of the superior qualities it has over natural grass. It for instance does not require any sunlight or mowing and it can be used more often. However, when it comes to comfort, artificial grass is still no match for a well maintained natural grass turf. This report aims to provide a proposal to enhance the comfort, i.e. reduce the discomfort of artificial grass by altering the surface properties. It therefore is focused on artificial grass that is designed to be in contact with human skin, such as artificial sports grass like soccer or field hockey. The report starts off with a description of several different kinds of artificial grass. Thereafter, it is investigated what types of discomfort or injuries typically result from using the turf, after which the underlying reasons for this discomfort are investigated. This eventually leads to a number of possible solutions and a final conclusion.
Artificial grass, mostly used as football/soccer grass, or golf grass, is a synthetic material which is manufactured with plastic and is easy to install. Pay heed to all these points before you install it in your home.
[b]PROS[/b]
Aesthetically Pleasing It looks lush green, is always well-manicured and has an aesthetically pleasing look in all the seasons. Unlike real grass, it does not get damaged by external weather conditions like rain or harsh sunlight.
[b]Maintenance Free[/b]
Artificial grass is stain-resistant, does not create muddy footprints, is low in maintenance and does not require herbicides, pesticides or fertilisers to grow. Since it does not need to be watered, it helps in preventing water usage without compromising on the aesthetics of the landscaped lawn. However it needs to be cleaned and sanitised periodically to prevent the growth of bacteria.
[b]Looks like Real Grass[/b]
Artificial grass mimics the look of real grass and is available in different blade lengths, textures, density and shades of green. It can be used outdoors or indoors. Since it is a flexible material, it can be cut and installed as small strips between the walkway pavers.
[b]Pet-Friendly[/b]
It cannot be dug and spoilt by pets. Make it a point to immediately remove pet waste from artificial grass and clean it with soapy water to minimise odour and prevent it from becoming a potential health hazard. Also, it will be perfect for just landscape grass, or a patch of decoration grass.
[b]Resistant to Fading[/b]
This type of greenery is UV resistant which prevents the grass from fading in sunlight. As a result, artificial grass maintains its green colour throughout the year while natural grass may turn brown in the presence of excessive sunlight.
[b]Highly Durable[/b]
It is long-lasting and can be used for upto 10 to 15 years depending on its quality and maintenance. If installed in a shaded area it will last longer than real grass which is exposed to direct sunlight.
[b]Artificial Turf Versus Natural Grass[/b]
The benefits and risks associated with natural grass and artificial turf playing fields have been the subjects of multiple studies. But few have examined the safety of these surfaces in high school sports — and none have examined the risks in high school sports beyond football. Also, the maintenance of a mini football grass won't be so high.
Artificial turf, including the the use of leisure grass, is easier to maintain, doesn't require water or fertilizer and can accommodate a variety of activities. With artificial turf, students can practice on the field in almost any weather without damaging the ground. Also, artificial turf doesn't freeze in the winter or thin out in the summer.
Dr. Voos says parents may want to ask coaches and athletic directors how they maintain their turf to keep students safe. "The main thing we want to emphasize is for parents and students to be aware of the difference," he adds. "Make sure kids have the right shoes in good condition, appropriate helmets and proper protective equipment."
The most popular use of artificial grass is to install it in a residential grass garden to replace an existing lawn as garden grass.

Chinese Shang Ring adult male circumcision (SC) is a safe and effective procedure which is easy to learn and to perform. By a specially designed small device, male circumcision (MC) can be performed in 5 min. Compared with conventional adult MC (CC), SC has shorter operation time, less blood loss, less pain score, higher appearance satisfaction rate, and lower complication rate. SC was first developed in China. As recent studies have demonstrated that MC reduced the risk of acquiring human immunodeficiency virus (HIV) infection via vaginal intercourse in African countries, SC was introduced into Africa to fight HIV. Other sexually transmitted diseases such as human papillomavirus infection may also be prevented by SC. In conclusion, Chinese Shang Ring, a small device, provides an easy, quick, safe, and effective method to perform adult MC.
Circumcision is an operation to remove a male’s foreskin. It is one of the oldest and most common surgical procedures. A male may undergo this procedure for religious, social, medical, or cultural reasons.
The Centers for Disease Control and Prevention (CDC) encourage male circumcision on the basis that it appears to reduce the risk of HIV infection during vaginal sex. However, not all health authorities agree, and the recommendations remain somewhat controversial.
Adult circumcision device is fairly commonly used in the United States. In fact, according to the CDC,  58.3%Trusted Source  of U.S. newborns underwent circumcision in 2010.
It is less common in other Western countries, however. In the United Kingdom, for example, only around 8.5% of males are circumcised.
This article will discuss what to expect during the procedure itself, as well as some possible benefits and risks.
the risk.
Evidence has indicated a lower risk of some sexually transmitted infections (STIs), including syphilis. Circumcised males, using male circumcision device, also appear to be less likely to contract herpes or HIV.
In very rare cases, balanitis or phimosis can develop in an uncircumcised male. With these conditions, the foreskin cannot retract. This requires surgical treatment.
Cancer of the penis is extremely rare, but it appears to be slightly  more commonTrusted Source  in males with a high body mass index (BMI), males with a history of smoking, males who are uncircumcised, and those with a combination of these factors.
According to the World Health Organization (WHO), there is “compelling evidence” to suggest that adult circumcision device reduces the risk of contracting HIV during vaginal sex by  60%Trusted Source .
However, they point out that circumcision will offer only partial protection, and they urge people to use barrier methods such as condoms as well.
The higher chance of infection may be because the foreskin becomes more prone to splits and ruptures during intercourse, allowing pathogens to enter the bloodstream.
Another possibility is that the space between the penis and the foreskin might provide an environment in which a virus can survive for a period of time, raising the risk of infection for the individual and their next partner.
Some argue that the U.S. has a relatively high rate of HIV despite high circumcision rates. In addition, the results of studies in Africa and Asia associating circumcision with HIV prevention, mainly in heterosexual populations, may not translate to the U.S.
Risks
Circumcision is a relatively safe procedure, and severe complications are rare.

Electrical Muscle Stimulation (EMS) has always been a little confusing to performance coaches and sports medicine professionals because the research is cloudy at best. Many of the reasons behind the limitations of science are the ethical boundaries you need to navigate, and the expectations you have with the results of those studies. I recently spent more time working with EMS, as more and more athletes are using EMS devices on their own and we are dealing with the hangover of injuries still lingering in the off-season. What I have learned is that the science is not perfect and there are no best practices.

PVP-Polyvinylpyrrolidone is a nonionic water-soluble polymer and can be applied in a variety of fields-of-use owing to following advantageous characteristics.
1. Good solubility in water as well as various organic solvents
2. Good affinity to various polymers and resins
3. High hygroscopicity
4. Good film formation property
5. Good adhesiveness to various substrates
6. Good chelate / complex formation property

Polyvinylpyrrolidone (PVP) is a water-soluble polymer obtained by polymerization of monomer N-vinylpyrrolidone. PVP is an inert, non-toxic, temperature-resistant, pH-stable, biocompatible, biodegradable polymer that helps to encapsulate and cater both hydrophilic and lipophilic drugs. These advantages enable PVP versatile excipients in the formulation development of broad conventional to novel controlled delivery systems. PVP has tunable properties and can be used as a brace component for gene delivery, orthopedic implants, and tissue engineering applications. Based on different molecular weights and modified forms, PVP can lead to exceptional beneficial features with varying chemical properties. Graft copolymerization and other techniques assist PVP to conjugate with poorly soluble drugs that can inflate bioavailability and even introduces the desired swelling tract for their control or sustained release. The present review provides chemistry, mechanical, physicochemical properties, evaluation parameters, dewy preparation methods of PVP derivatives intended for designing conventional to controlled systems for drug, gene, and cosmetic delivery. The past and growing interest in PVP establishes it as a promising polymer to enhance the trait and performance of current generation pharmaceutical dosage forms. Furthermore, the scrutiny explores existing patents, marketed products, new and futuristic approaches of PVP that have been identified and scope for future development, characterization, and its use. The exploration spotlights the importance and role of PVP in the design of Povidone-iodine (PVP–I) and clinical trials to assess therapeutic efficacy against the COVID-19 in the current pandemic scenario.
PVPP is a synthetic, high-molecular-weight clarifying agent made up of cross-linked monomer of polyvinylpyrrolidone. PVPP has long been used in the beverage industry as a polyphenol adsorbent. Although, it has been called as a “protein-like” fining agent, insoluble PVPP interacts with only few reactive groups. Hence, PVPP is used for binding and removing smaller phenolic compounds such as catechins and anthocyanins, which are responsible for causing browning and bitterness in wines. However, PVPP, along with charcoal and casein, can remove resveratrol, a component that imparts certain health benefits.
Polyvinylpyrrolidone (PVP) is a linear polymer of 1-vinyl-2-pyrrolidone monomers used as a binder, emulsion stabilization of suspensions, film former, hair fixative, and suspending agent-nonsurfactant. The molecular weight of the polymer ranges from 10,000 to 700,000. PVP K-30, with an average molecular weight of 40,000, is typically used in cosmetic formulations. The highest concentration reported to be used is 35%. There was no significant absorption of PVP K-30 given orally to rats, and

Anyone who has a very busy schedule will tell you that a power bank is their lifesaver. A power bank is essentially a portable charger. Power banks are most commonly used to charge cell phones but are often also used to charge laptops, speakers, and various other chargeable devices.
In this age, our cellphones contain our entire lives in it, be it a photographer’s photographs, to an entrepreneur’s documents. When you are on the go at most times, it’s virtually impossible to find wall outlets everywhere to charge your phone if the battery drains. A conventional power bank prevents you from running into a crisis when your phone suddenly turns off when you need it the most.
Keep on reading further for more about power banks, and what impact they have on your phone’s battery.

With the accelerated pace of human life, disposable tableware has gradually entered the fast food business. Since the first use of disposable tableware in China in 1984, foamed plastic tableware with polystyrene (eps) as the main raw material has spread all over the country and entered people's daily life, forming a huge consumer market. According to statistics, at present, China consumes about 10 billion fast food appliances each year, most of which are disposable foam plastic tableware, and grow at a rate of 25% per year.

We need a variety of boxes when we’re relocating for ease of transportation and protection of our belongings. These moving boxes are meant to be temporary and are commonly made from cardboard.
Cardboard moving boxes should be used for their primary objective – moving. But it’s not unusual to store items long term in these inexpensive boxes. The misconception stems from the idea: pack it once, decide if you need the item right away, and if not, put the box in storage, wherever that might be – garage, attic, basement, shed, or off-site storage.
Concrete slabs and outdoor flooring, if not sealed properly, will seep moisture, and if you have cardboard storage bins on the ground, it will then absorb the moisture and get the items in the box wet. If this happens, your items will become ruined and mildew or mold will start growing in the box.
If you have chosen to stack cardboard boxes in this situation, the bottom box walls have now become compromised, and there is a chance of the stack falling.
How to Store Cardboard Boxes Properly
1. Maintain Your Storage Area

When to Use Plastic Bags for Storage
Storage boxes come in various sizes, and you don’t need tape to put them together. They usually have locking lids, and best of all, the clear ones can help you see what you are storing – a great start to helping you get or stay organized.
When determining what long term storage box to use, make sure you consider the conditions of your storage area. Sometimes you can get away with cardboard boxes, and other times it’s best to stick with sealed plastic totes. Not sure where to source quality cardboard boxes? Visit any of our Life Storage locations for moving boxes in a variety of sizes.
