Geosynthetic Products And Their Uses Geosynthetic Products And Their Uses June 14 Cheap Jerseys , 2013 | Author: Liliana Mills | Posted in Education
Geosynthetic products are commonly used in a wide range of applications and serve a variety of purposes. They are generally made of polymer, which makes them suited to use in the ground. In this environment, a high level of durability is necessary due to the harsh conditions that erode natural products. There are a number of different types of these products that can be used depending on the exact needs dictated by the situation.

The idea of using products to stabilize soil was used as long ago as ancient Rome. The Romans used a mixture of natural materials with soil for stabilizing roads. The ancient Egyptians used similar methods for building steep slopes as in the pyramids.

The problem with using natural materials such as wood or cotton in this way is the fact that such materials, when buried in the soil, will inevitably be subject to biodegradation, the wearing away caused by microorganisms in the ground. In the 20th century Cheap NFL Jerseys Wholesale , the introduction of polymers made it possible to produce much more durable materials that can withstand such conditions.

Uses of geosynthetics can be classified into five general categories. At times they are used to separate different types of materials so that the functioning and integrity of the materials are either maintained or improved. Separation is a common application for railroad bases as well as paved and unpaved roads.

Reinforcement is another common function of this type of product. This occurs when a type of geosynthetic is used to improve strength, as with loose soil. Retaining walls and steep slopes are two examples where reinforcement is useful.

Filtration is yet another common application. This purpose involves allowing liquid to move across the plane of the geosynthetic without allowing soil to be lost. Retaining wall drainage, containers and tubes are instances where filtration is of value.

Drainage is different from filtration in that it involves allowing the flow of liquids within the plane of the product while preventing soil loss. Sports fields, reservoirs, dams and canals are places where this function is important.

The final application is as a barrier for gases or liquids and is known as containment. Hydraulic applications like canals and tunnels apply this use regularly.

These types of products have a number of distinct advantages in addition to their ability to withstand degradation. When compared to using natural soil, geosynthetic materials tend to be more cost-effective and involve a lower CO2 footprint as well. Also Cheap NFL Jerseys China , due to the relatively light weight, it is easier to install these products than to have to move large amounts of soil, rock or other natural materials.

As with anything, there are some disadvantages too. The storage, handling and installation of these products must all be performed with tight restrictions. This may lead to a need for more training and supervision. The fact that they donít biodegrade is a major advantage but may also have some negative environmental impact in the longer term.

In short, geosynthetic products are generally seen as a valuable resource with a number of practical applications. They have successfully replaced natural materials in many instances and promise to continue doing so for quite some time.

Washingtons Magic Number For Division Title Is One - RealGM Wiretap

The Nationals defeated the Cardinals on Saturday, cutting their Magic Number to one as they look to win the National League East.

Washington has put on hold a champagne celebration until they win the division. They clinched a playoff berth earlier this month.

锘? The Nintendo Wii Fit was released to the public recently with much ballyhoo. If you haven't seen the Nintendo Wii game system, it is the latest evolution in video game playing where players use the remote to mimic real-life actions such as a tennis forehand. The players' physical actions are then played out on the screen.

The Wii Fit is a "game" that according to the Nintendo website can increase your fitness levels. "By playing Wii Fit a little every day, you, your friends, and your family can work towards personal goals of better health and fitness Cheap Jerseys Wholesale ," the site claims. While I have yet to use the game at all, I can say that I am highly skeptical that this will make a dent into America's growing obesity problem.

The Wii Fit comes with a balance board that the player uses to interact with the game. When you first start the game, the Wii Fit assesses your balance - which is important in your overall health, but is usually not a concern to anyone who is not a senior citizen or recovering from injury.

It then moves on to perform the Body Test, which is more balance assessment, followed by the calculation of Body Mass Index (or BMI). BMI is a very flawed measure of one's fitness Cheap Jerseys From China , as it measures the ratio of one's scale weight to one's height. So, on the BMI scale, the following people are considered Overweight or Obese:

- Alex Rodriguez of the New York Yankees
- Tom Brady of the New England Patriots
- Lance Armstrong of cycling fame
- Arnold Schwarzenegger
- Sylvester Stallone

See where I'm going with this? Scale weight does not account for the amount of lean body mass someone is carrying. That is why body fat percentage is the gold standard for measuring one's fitness.

Also, measuring BMI on anyone under 19 is very inaccurate. This alr. Forum Index -> Serious Games Section
