Soundproofing has become compulsory for many of us, as noise pollution stands for a fundamental disturbing element in our lives. There is an endless list of factors having generated all sorts of issues related to the need of sound insulation. First of all, space reduction has severely affected comfort in residential terms, and all has started with the insulation of homes. By extension, noise has become the enemy in many of our daily activities, it has generated what we usually call acoustic pollution. The common solution to all these problems was a sound absorbing material, which could have easily helped dwellers regain the lost comfort. As per statistics, sound barrier walls have been more than welcome.

This is why, these solutions have become fundamental building materials for the new generation of buildings. Of course, sound insulation comprises all sorts of methods and materials as we can fight the side effects of noise in so many ways. For example, room within a room is a method creating a virtual barrier, which can fight against sound energy. Although windows have been the traditional way to annihilate the noise, this method can no longer cope with the challenges of the modern world. Thus, constructors are on the lookout for advanced solutions, and the basic option was full or partial coating of a certain room. This method may fall in different categories, according to the type of material, or the inner structure of the material.

At first glance, soundproofing might seem an auxiliary demand in residential or commercial building projects. Nevertheless, choosing a sound insulation alternative, the overall value of the building might considerably increase. In addition, it is highly recommended to integrate soundproofing in the building process, simply because, it saves money and time. Although a certain building plan has not comprised soundproofing, owners still have a second option, soundproofing may be attained after the building process has been completed. In general, this alternative is correlated to a renovation plan, but, sound deadening plan may require deep removal of the decorative layers of the interior walls or of the ceiling, therefore, it is wiser to synchronize sound proofing with a renewal plan.

All in all, soundproofing is a must, yet, although many consider that complete sound insulation is better, we need to outline the fact that this option might become too risky, that in case of emergency, we are unable to send out signals that eventually might save our lives.

Just like the sport of mixed martial arts has evolved, so has the competition gear athletes wear during combat. During its humble beginnings as an underground, bare knuckle, anything goes format, athletes wore whatever helped them survive and win. This included anything from going shirtless to wearing full martial arts gis. With the emergence of the UFC came a minimal set of rules and standardization of gear as well as a wider, much more accepting viewing audience. Now, standard protective equipment include a pair of fingerless 4oz. gloves, mouthguard and groin cup. The uniform seen worn by most fighter is simple … a pair of fight shorts.

With mixed martial arts being comprised of numerous fighting disciplines, apparel worn for practice and actual combat must have certain features to accommodate whichever style the athlete specializes in. Regardless of individual style preferences or what discipline the athlete may have started with, fight shorts must have features that will allow both grappling and high kicking. While some styles of shorts definitely work better for certain fighting disciplines, there are still some general features that are must-haves regardless of what your favorite moves are. For example good fight shorts must have exceptionally durable material to withstand being slid and scrubbed against the floor and cage walls of the ring. Look for shorts with material that has an elastic property that will stretch against the bends of the hips and legs for the best range of motion. Shorts with materials that have less give may be very limiting for certain techniques.

When shopping for fight shorts, choose above the knee lengths to avoid trapping the material within the knee joint when grappling and ground fighting. Fight shorts should not be tight (unless they are compression gear) and best if comprised of slick type material rather than rough, canvas type to prevent friction against the mat or your opponent. The waist of good fight shorts should be comfortable but above all secure so they stay put. Some shorts have elastic waistbands while others offer Velcro enclosures but all should have a draw string of some sort for a tighter, more adjustable fit. Do not wear shorts with pockets or loops of any kind or they can get snagged during combat. Good fight shorts will be smooth all over the sleekest action and best performance.

If you want to be a pro MMA fighter, it's smart to emulate what the pros do and copy what they wear when they're in the cage. Even though your style of fighting may be different than theirs, doing this will at least give you a place to start. It seems the most popular MMA shorts are knee length and look like they could double as a pair of board shorts you also see surfers wearing at the beach. This style of shorts offer a comfortable fit with just enough snug in the hips but still plenty of room in the thighs to feel secure while pulling off all your moves. The length of MMA fight shorts offers plenty of space for advertising making them ideal for sponsorship logos, crucial to your career as a fighter.

Before buying a pair of MMA fight shorts, make sure you have the right fit. Some of these shorts have fairly thick material, making them extremely durable but slightly less flexible. If MMA shorts are even a bit to snug, their lack of stretch may limit your range of motion or change the way certain moves feel. As long as they fit correctly, MMA fight shorts are great for fighters who like to stand and box but not use many head kicks and mostly stay off the ground. They also work well for wrestlers however there are better choices for pure grapplers. The best MMA fight shorts for wrestlers are made with slicker material to allow faster action yet still provide good traction against the floor.

Muay Thai fight shorts are also seen worn by pro MMA fighters in the cage but mostly by athletes who specialize in this discipline. These shorts are worn by kickboxers so they are very baggy and offer the best range of motion for high knees and kicks to the head. They're also great to wrestle in because they are made with satin or silky type material so they're very slick on the ground. Muay Thai shorts are mid-thigh or higher and have wide, soft elastic waistbands much like shorts seen in the boxing ring so they are probably the most comfortable to wear. Drawbacks may include how loose they are on the legs. While this is a plus for performing kicks and knees, Muay Thai shorts tend to ride up the thigh very easily when grappling causing too much exposure for some athletes. This is easily remedied however by wearing a pair of compression shorts underneath. Most Muay Thai fight shorts are brightly colored and have some kind of Thai writing across the front and / or back. This means they are not ideal for displaying sponsorship company logos so for advertising purposes, these may not be the best shorts.

If you're looking for a garment that offers the most versatility for mma, a good pair of Vale Tudo shorts is the best you can get. These shorts look like a pair of short length compression shorts so they are definitely the most revealing, however allow the best range of motion for all possible techniques used. Vale Tudo was a 'no holds barred' fighting venue that preceded MMA with tournaments mostly being held underground (not widely publicized) because they were so rough. Vale Tudo fighters mostly used Brazilian Jiu Jitsu and a range of striking techniques, very similar to modern day MMA (just with even less rules). Fight shorts worn for this type of martial art were best for grappling / BJJ but also allowed the freest ability for all / any striking methods as well.

In the cage, Vale Tudo shorts are excellent for both wrestling and throwing high kicks. You will never have problems with extra material getting in the way, causing extra friction or slowing you down as with traditional MMA shorts when you wear Vale Tudo shorts. These garments slide nicely against the ground when grappling providing the sleekest movement for close but also your stand-up game. The only disadvantage of Vale Tudo shorts are they may be too revealing for some athletes who may be uncomfortable wearing them in front of a crowd as they are a type of compression gear so they are skin tight. Short length Vale Tudo shorts are only about mid-thigh and also do not leave much material for advertising space regarding potential sponsor logos however their performance trumps this drawback.

Neoprene is a synthetic rubber material designed to be flexible, durable, and to resist breakdown by water. Neoprene has been used for over 75 years. In its application to braces and supports, it is very form fitting and resilient to the stresses placed on it.

Neoprene is a very popular material for cold weather sports such as skiing and snowboarding, and is used extensively in water sports.

Neoprene braces are ideal supports to provide uniform compression over an extremity such as the knee or elbow. Neoprene's heat retention properties is preferred by some to help ease the pain of a joint due to arthritis and muscle strain.

The disadvantage of Neoprene is know to many parents who pick up their child's brace, with an odor that is hard to describe and tolerate. Neoprene is not a breathable material, and therefore retains the sweat and perspiration of the skin at the surface. Many people have allergies to Neoprene, causing skin rashes, blistering, itching and more severe allergic reactions.

Elastic material is not a good alternative as it does not stretch like neoprene, nor does it have the compressive qualities and durability of neoprene.

DonJoy developed a material referred to as "Drytex" as an alternative to Neoprene.

Drytex is a material made of a Nylon core and Polyester Lycra fabric, which retains the durability and compressive advantages of Neoprene, but is breathable and non-allergenic.

Drytex braces are more comfortable to wear compared to Neoprene, with the absence of the foul odor usually associated with its counterpart.

So how do I tell the difference between the two materials?

Simply lift the material up to light and stretch the material. If light shines through, it is a breathable material. If there is no light seen, it is probably neoprene.

If you are in a warm weather climate, and participate in sports such as Basketball, Football, Soccer, Tennis and Golf, then Drytex is an alternative to Neoprene. If you have allergies to Latex and Neoprene, Drytex is an excellent choice for support.

This material is only found in select manufacturers like DonJoy. It usually is not found in retail stores.

It is important to consult with your treating doctor prior to purchasing any orthopedic brace. There are many choices to be made when deciding which knee brace to purchase.

Materials used for the construction of houses, offices and commercial buildings are classified as building materials. The most commonly use materials for construction purposes include cement, stones, rocks, tiles and bricks. Different materials are used according to specific requirements, availability of space and type of structure to be built.

Building Materials Used Before and Now

Building materials used during early years were stone, mud and other materials. Instead of concrete, mud was used to fill the gaps between bricks and stones. Construction was done using crude methods and techniques. Clay, leaves, twigs and so forth were also used by people in the olden days to build houses.

Some of the most frequently used building materials include:

Clay and mud: During the earlier days , clay and mud was the most commonly used material though it was not as strong as the concrete constructions. However, it helped to keep houses cool during summers.

Wood: Another most frequently used material is wood. Down the ages, wood has been used by people to build homes, furniture like tables, desks, chairs and so forth. Wooden homes and cabins are found in many places even today. Depending on the type of wood used, these houses are affected by varying climatic conditions.

Metal: Metals are also among the commonly used building materials. Huge mansions and offices built of metals are strong and last for a life time. Today most of the constructions are done in metal to retain its elegance and strength.

Concrete: Concrete is another material which is used for construction purposes. It is a combination of sand, cement, water and gravel. Most of the constructions are done in concrete today. It has become an indispensable part of construction process. It is long lasting and strong compared to mud and wood houses.

Granite: Being one of the hardest materials available for constructing walls, floors and kitchen accessories, this stone has been in use since ancient times. Granite countertops are among the most preferred material for kitchen countertop. Its durability and opulence are the main reasons why it is chosen by most of the people to decorate their homes.

The other advantages of this stone are that it is highly heat resistant and can be cleaned easily. It does not retain any stains and bacteria. Though it is a bit expensive, it is indeed an investment which last for a life time.

Apart from these there are many more building materials used in the modern times like non shrink grouts, multi-wall panel, steel roof drain, crushed stones, wall putty, insulation products and so forth. Brass materials are also used for construction purposes.

Today the business of building materials has flourished with the increase in constructions of houses, factories, industries and offices. New products are available in the online stores at affordable rates. In addition to construction materials you can even find flooring materials which are quite versatile. Marbles, tiles, granite in unimaginable sizes and designs are obtained from the online markets. By logging on to a good website, you can find materials for your new home and office.

There are many products on the market that claim to be green. It is up to you to determine which products are green and which are not. Beware of "green washing"! Many products are advertised as green, but after review really do not live up to their claims. Here are 7 factors to consider when selecting green or sustainable products and materials for your project.

Renewability – Are the products made ​​from material that is rapidly renewable such as cork or bamboo? Wood products are also a renewable resource. Choose wood products that are FSC (Forest Stewardship Council) certified. Many engineered wood products are made from fast growing trees such as aspen and require less wood to make them than conventional lumber.

Recycled Content – Using material with recycled content not only reduces strain on our landfills, but reduces the need for raw material. Paper, cardboard, plastic, steel and aluminum are a few of the most commonly recycled materials. Recycled paper is used in cellulose insulation and paper countertops. Plastic is used in carpet. Metals that are recycled can be made into their original form.

Reusability and Recyclability – Many products, such as metals, can be recycled after their useable life. Others can be salvaged and reused somewhere else.

Durability – Choose products that will stand the test of time and require little maintenance. This will save time, money and energy on repairs at a later date.

Embodied Energy – This is the energy used to produce, transport and install a product or material in the place where it will be used. Choose local products when possible and products that do not require a large amount of energy to produce.

Air Quality – Products like carpet, cabinetry , plywood and paint can contain petroleum products or formaldehyde and off gas VOCs (Volatile Organic Compounds). There are now many products available that give off little or no VOCs. These products will give you a healthier home to live in. When you are not able to find suitable products, ventilate the new or remodeled space prior to moving into it. Open windows and doors when possible to remove the VOCs from the home.

Waste Reduction – Choose material that does not create a lot of waste and can be used efficiently. Order material in sizes and lengths that are efficient for your job.

Some products may be green in one area but not in another. Example: Although it is very durable, brick has a high embodied energy because of the energy used to fire the kilns and transport it. It would be a greener option for someone in North Carolina than someone in New York because the clay that is used to make it is a local product. Use these 7 factors and your best judgement to determine which green products are the best for your project.

For most home owners the garage door came with the house, and few of us give it much thought other than to make sure it was open when we drove through it and closed at night when we locked up the house. But when it comes time to replace an old worn out door, we are suddenly confronted with an array of choices we did not even know existed for garage doors.

The first choice you must make is what type of material you want your garage door to be made of. The most popular material is steel. Steel is reasonably priced, low maintenance, and is available in a faux wood or can be custom painted. The quality of steel will vary depending on the gauge of steel. Thin steel at 27-28 gauges will dent easily but be a less expensive steel door. A mid level 25-26 gauge is at a mid range price that will not dent as easily as the thinner gauge. The highest quality steel is a 24 gauge door that should be able to endure more impacts and bumps without any surface impacts. Steel is not as good of an insulator material as wood, but it can have insulation added to make it more energy efficient.

Wood doors were the original door material for garages and have the advantage of being a good insulator against the elements. Wood can be painted or stained depending on preference, but it also requires high maintenance and if it is neglected it can crack, split, and experience expansion or shrinkage, so it should not be the material of choice unless you are prepared to maintain it .

Wood composite doors are a little more expensive than steel doors but cheaper than wood doors and have the advantage of looking like wood but not requiring the high maintenance of wood. The wood composite doors can be made out of a variety of composite materials including plastic and wood fiber or wood and resin. This type of material can resist cracks, splits, rotting, shrinkage and expansion. It can be a good door choice in a mid price range that offers the best of both steel and wood.

Vinyl and aluminum are two other material choices that are not very popular because they dent easily, look cheap, and do not hold up to the weather or time as well as other materials. The only good thing about this type of material is it is cheap, so you get what you pay for with it.

Figure out how you want your door to look, how it will be finished, if you need to withstand the elements of heat and cold, wind or rain, and then pick materials. Of course, the next step is to decide what style you want, but that's a whole new discussion.

High Performance Liquid Chromatography (HPLC) is used as an analytical instrument to separate certain compounds in a sample. The HPLC consist of a pump that delivers the mobile phase and sample throughout the system, an auto sampler or injector port for sample introduction, a stationary phase where separation of compounds takes place, a detector to detect the compounds and an integrator or a computer system for the visual output.

HPLC first started with normal phase. Normal phase HPLC means the stationary phase is made of polar packing material while the mobile phase is of non-polar or low polarity solvents. Commonly used polar stationary phase or column is packed with silica. Silica is relatively the most polar compound compared to all other packing materials. Another polar column is cyano column which has a more intermediate polarity. Examples of solvents used to make up a normal phase mobile phase are hexane, dichloromethane, chloroform, ethyl ether, and isopropyl alcohol (IPA). Most of the solvents used in the mobile phase are water immiscible and have low polarity. In most cases, these solvents are used together in a mixture of in order to achieve compounds separation. For example, Hexane: IPA (9: 1) means the mobile phase consist of a mixture of hexane and IPA at the ratio of 9 to 1. In a normal phase application, the non-polar compounds will be eluted faster than the polar compounds .

In the 1970s, reverse phase HPLC was developed. The principle is opposite of normal phase system, where the stationary phase is packed non-polar material and the mobile phase is polar. Commonly used packing material in reverse phase columns are silica linked with carbon-18 (C18). There are other columns of more intermediate polarity, such as C8 and cyano. Note that cyano can be used in both normal and reverse phases and some column manufacturers produce two types of cyano column to suit each phase. The mobile phase for a reverse phase system usually consists of water or buffer solution, methanol, acetonitrile and IPA. IPA can be used in both reverse and normal phase as it is miscible with water as well as water immiscible solvents. However, large amount of IPA in a mobile phase will cause high pressure in the HPLC system due to its high density value. In a reverse phase HPLC, the non-polar compounds are retained in the column longer than the polar compounds. In another words, the polar compounds elute faster than the non-polar compounds.

Most people take buildings and structures for granted. They overlook the fact that these structures are laid down and constructed one small piece at a time. It is actually these small solid pieces that make up structures ranging from simple buildings to mega structures. The common belief that cheaper is always better is flawed when it comes to building materials. Hereon, we will discuss the role of building materials in construction works.

Building materials can range from simple bricks, cements and tiles to more intricate tools such as safety equipment and tools. These raw materials are the bread and butter of building your desired structure. Therefore choosing an appropriate supplier for your structure would be the foundation of your building and one of the most important decisions you would have to make. The problem with the society is that people are willing to slack on quality to save costs. However, working with a good supplier can help you get good deals at reasonable prices for your materials as well as labor charges.

Generally the suppliers are the ones who are in charge of making the final distribution of building materials to the clients. Therefore they would have the best perception on the quality of the materials. Choosing a reliable and trustworthy supplier can ensure that you get the highest quality materials at affordable prices. It is also important to note that the quality of building materials can not be overlooked if you wish to construct a structure which is both physically and technically safe and sound. The poorly designed structure and low quality materials used are the primary reasons contributing to the collapse of the Sampoong Department Store in 1995, which resulted in widespread damages and loss of lives.

A reliable and knowledgeable supplier would know what you require for your building by looking at your tender plans. Occasionally, building materials require a certain degree of product certifications to ensure that materials used are quality controlled. Product certification is not mandatory on everything but a knowledgeable supplier would know and distribute materials that are. Some of these suppliers will have incorporated product quality systems to ensure that materials used comply with building codes and statutes. These incorporated systems ensure that the materials used meet minimum building code performance requirements.

Choosing the supplier which synchronizes well with your project can help ensure that materials get delivered on time. Constructions of structures are considered to be hefty investments and the contractor or owner might not be able to afford any unforeseen delays or glitches. Besides timely delivery of materials, reliable suppliers may also provide warranties for defect materials delivered.

Besides raw materials like bricks and tiles, safety equipments and tools are also essential for the development and construction of a building. Construction workers put their lives at risk when they scale high rise buildings to lay a brick or tile. Scaffoldings and harnesses are an important part of construction work as they help prevent unwanted accidents from happening. Safety tools such as paddings, helmets and protective clothing help protect workers from getting injured during the construction process. Together, they help provide a safe working environment for workers to lay the basic building materials to put together the final finished structure.

Vinyl composite tile, also known as VCT, is a material preferred by many contractors and builders for floorings and walls. If you look at the floors and walls of new or newly renovated hospitals, schools, warehouses, factories and other commercial and industrial establishments, you will realize that most of them use VCT.

Although VCT is popular for commercial and industrial uses, there is no reason for you not to use this type of material for flooring at home. In fact, more and more households in the country are making use of vinyl tiles as an alternative to conventional flooring materials. In order to help you decide whether vinyl is best for you, check out the comparison between vinyl and other types of flooring materials.

Vinyl composition tiles are popular because they are not only affordable, but they are strong and durable as well. The average life span of vinyl tile flooring, particularly the one that is made of the highest quality, is around 15 years. For something that costs $ 2 to $ 5 per square foot, this can really be a good deal.

Besides, vinyl floor products that are sold in the market these days can be made to imitate the texture and appearance of most traditional materials. Furthermore, VCT comes in different colors, designs and styles. Whatever the motif or design of your home is, you will surely find a tile that will perfectly fit the look of your home interior.

It is without a doubt that wood is more durable and stronger than vinyl tiles. Even if you buy the most expensive VCT, well-maintained wood will still outlast the VCT when it comes to lifespan. Besides, wood flooring is also elegant and timeless. However, wood is very expensive, at least three times the price of ordinary vinyl. Wood can also warp or bend due to water damage.

When used for years, you will also see expansion and contraction of wooden materials. With VCT, you will not have a problem with water damage because this material is resistant to moisture. In case some areas of the vinyl flooring are chipped or damaged, you can easily replace the affected areas.

Carpet flooring is another preferred type of flooring in the US. This is also inexpensive and it comes in different designs and colors. However, carpet is quite difficult to maintain.

With vinyl composite tile, you will not have this problem. Cleaning and maintaining VCT flooring can be very easy and convenient.
