Researcher Addresses Questions About Pros and Cons of Genetic Engineering
Twenty years ago, when agricultural biotechnology was a novel term, there was discussion about the pros and cons of genetic engineering in agriculture. Since that time, scientists, academic institutions and government agencies have conducted research on the safety and
Slate Information
Metamorphic Rock Natural Stone Slate is formed through metamorphism, a process in which the tiny elements that make up a rock are pushed closer together to form a crystalline structure, also known as recrystallization of the stone. This all occurs while the stone is in a solid state, and the materials that make up the stone are not changed, they are merely repositioned to be closer to one another in a crystal pattern.
4 great reasons science projects make your child smarter
There are many educational things you can do with your child to make them smarter. You can make them read books, or make them study more, or you can have them do a science project. You might be thinking that there is no way your child would do a science project. Doing science projects can be fun and educational all at the same time.
2007 awareness global warming
Composite findings of scientists do not debate well for future years due to the alarming rate the earth's atmosphere is warming up. The world is being warned of hunger and thirst for millions due to global warming. The continuous emission of gases such as carbon dioxide and methane has become worse, the situation especially in the recent years.
Research Online: Where and How To Start
Researching online is probably the easiest way of finding any imaginable information in scarce time period. Every year there are a lot of new sites that are appearing on the Internet. Purpose of a certain amount of them is to help Internet users in finding, identifying and downloading information. These sites are getting more and more sophisticated with every year.
Nostradamus Prophecies Linked to the Nazca Lines
Michel Nostradamus, history's most famous prophet, died in southern France in the sixteenth century. The lines of Nazca are one of archaeology's greatest mysteries and were created nearly a thousand years earlier on a faraway continent. A direct connection between the two is surely impossible, no "To the contrary, it's highly possible," says Morten St.
Microhardness Testers (MHT) are used to judge and signify the rigidity and stiffness of materials. This is usually done by creating a localized point of penetration by making use of a standardized rounded or pointed indenter made of carbide, diamond or hard steel.
The tester is basically an instrument of accuracy used to verify the micro mechanical characteristics of thin external layer and substrates. With MHT, you can determine qualities like hardness and Young's modulus of almost all sorts of materials - tough, supple, fragile or soft.
How much load can MHT bear The amount may vary from 10mN to 30N. Such a wide range of load carrying capacity allows a measurement of coatings down to 1 or 2 microns without being affected by the material of the substrate. The Microhardness Testers is competent enough to carry out all ASTM tests and is quite able to meet up the space between conventional and mechanized indentation procedures. A standard micro hardness test like fracture toughness can be readily used by way of a dynamic mode. This is because the depth curve for some of the materials will readily exhibit the commencement of cracking in the stuff.
Essential features of Microhardness Testers
- Depth verses low curves - Fracture toughness measurements - Nano hardness, nano scratch - Hardness and Young's modulus - Mapping option - Unique Z automatic motorized approach - Creep, stiffness and fatigue tests - Integrated Video Zoom Microscope for easy determination of optical failure - Sample Heating and cooling holder from -196C to 400C. - Possibility to add Micro Scratch Capability Spherical, Vickers, Knoop and Berkovitch micro indentations
General applications of Microhardness Testers
- In the field of general engineering, Microhardness Testers act as a measuring tool for rubber resistance - It measures various wear resistant coatings like TiN, DiC, DLC and cutting tools - Pharmalogically Microhardness Testers are used to assess tablets and pills, implants and biological tissue - Its assessment of decorative coatings like evaporated metal coatings is also quite appropriate - In automobiles, Microhardness Testers are used to measure the thickness of paints and polymers or varnishes and finishes - A Microhardness tester can significantly measures the thickness of windowpanes
This unique tool is easy to use with maximum accuracy and precision.
