In recent years, millions of solar panels have been placed on roofs around the world. Discuss how safe are they? Discuss the hidden pollution caused by solar panels.

Throughout History Man has experienced alot of severe and fatal incidences that could have been averted or most assuredly minimized if certain actions were taken or decision making processes where in place.

Hi everybody, I am trying to write a program to read Nastran op2 files and I am having a lot of problem understanding the basic structure of these files. Anybody has a hunch ?

Hydrogel is known for its super absorbency of water allowing for a close resemblance in flexibility as natural tissue. This close resemblance has made Hydrogel a common choice not only in biomaterials, but also electronics, environment and consumer good application such as contact lens. The use and diversity in application have each their own unique needs and requirements. One such requirement will be known and controlled mechanical properties using nanoindentation.

Traditional Puncture Tests are typically used to determine the penetration characteristics of a wide range of protective material such as films, foils or membrane. It is widely used in food and medical industries on applications ranging from food packaging to rubber gloves and needles. The test is preformed like that of a compressive test. A probe, with multiple tip selection, uses increasing load until material is penetrated and load is recorded at failure.

Irvine CA, January 18, 2012 - Nanovea today announced the arrival of the N3 line dedicated to providing high-end measurement technology to the broader market. Nanovea has fully automated their measurement techniques while designing to price in the $20K market.

Why do we use "atmospheric flares (Burners)" in preheat gas furnaces of refineries? What are benefits of usage of these kind of flares (burners) in refineries, in comparison whit other flares?!!! 

The intention of shot peening is ultimately to alter the mechanical properties of a given surface. By hitting the surface with controlled shot the surface will deform plastically. Proper Instrumentation, nanoindentation, will play a vital factor in achieving reliable and intended results.

There is a new European regulation (10/2011) addressing plastic materials and components intended for food contact. It is important to understand this regulation to ensure compliance, thus protecting your company when it becomes effective. The new regulation applies to all unreinforced and reinforced plastics, including those that are reinforced with glass fibres. This presentation addresses glass reinforced plastics and the necessary changes that you should be aware of. To see more go to www.reinforcedplastics.com

Microindentation hardness mapping has been widely used to assess the variation of mechanical properties across a large surface area. However, with the study of applications such as glass it is the crack initiation that is of particular interest. It is for this reason that acoustic emission can be used during the mapping of indents to not only map hardness but also map the crack initiation values over the surface area.

Dear friends,

Looking for a possible solution of a problem with external axial friction moment on a shear bolt.I tried to get literatures related with this type of combined loading,but not succeed much.If u can help me it would be great!

When lubrication is applied to reduce the wear/friction of moving surfaces an increasing load can shift the lubrication from several regimes such as Boundary, Mixed and Hydrodynamic Lubrication. The fluid viscosity, the load that is carried by the two surfaces and the speed that the two surfaces move relative to each other combine to determine the thickness of the fluid film. It is this process that determines the lubrication regime. How the regimes react to friction is shown in what is called a Stribeck curve.

Mercury Marine outboards, engines, and drives are designed to withstand indoor impact testing (called “logstrike”) that simulates a collision with an underwater object. This test is comprised of an outboard or sterndrive device mounted on a mock boat that collides with a simulated log.

Paper transport is one of the areas under media handling methods where papers are transported by rollers through different path ways. The challenge in media handling is to transport the paper smoothly with out jam or in-plane deviation (paper skew). The smooth flow of paper is influenced by grade of paper, complexity of flow path, roller speed, roller pre-loads and significantly the roller material. It is also costly and difficult to develop a physical flow path testing.
