The phenomena of reacting to emotional scenes can be analysed by explaining mirror neurons. These are activated both when an animal performs an action and when the animal observes the same action being performed by another animal (especially belonging to the same species). The results of brain imaging experiments show that the human inferior frontal cortex and superior parietal lobule are active when a person performs an action and when the person sees another individual performing an action. It explains much about how we learn to smile, walk, talk, or play tennis. At a deeper level, it suggests a common neurobiological dynamic for our understanding of others and the complex exchange of ideas we call culture. Mirror neurons let you walk in other person’s shoes by creating an impression of you experiencing the same thing as the doer – be it reacting to sad scenes in movie or jumping with joy at an Indian cricket victory.
Created by a Japanese firm, the tangible 3D system allows users to not only see but also feel a three dimensional image with the help of a sensor-loaded glove. Possible commercial uses of this technology could include linking it to video phones, which will allow users to not only see but also even touch their loved ones, even if they are far away.
An Ozonizer is a purifier that creates ozone, a form of oxygen, to kill and/or filter out contaminants, such as bacteria, fungi and many viruses. Ozonizer creates ozone by charging the air with a burst of high negative voltage to produces ionized forms of molecules other than ozone. It acts like air and water cleanser which uses naturally occurring trace gases to exterminate microorganisms and filter a wide range of pollutants. Ozone is present in nature, mostly above the sea levels. It helps repel ultraviolet emission. Ozone is highly toxic to humans and other living things hence if below the atmosphere it can be risky.
Coarse salt is larger coarsely grained sea salt. You often see cooks on television using coarse salt that they sprinkle with their hands out of an open container. Coarse Salt is a variety of salt that is larger than common "table" salt. Coarse Salt is thicker than fine salt. Some examples of course salt are Kosher Salt and Sea Salt. It is also the type of salt that is used on meats and soft pretzels. It is made by evaporating sea water. The coarser sea salt's mineral content has less iodine than table salt, which is why some sea salts are now iodized.
Flash to Video Converter is a software program converting video formats with high quality. Flash to Video Converter is in one tool, convert all popular video, audio formats,to movies. For best results, look for a package that converts from multiple platforms into Flash. Two popular packages are Wondershare Video to Flash Encoder & iOrgSoft Video to Flash Converter. Adobe Premiere is very good, but Quicktime has free software for flash conversions. The best flash convrter is DVD Flash Video Converter. It's free and very powerful. It has easy-to-use interface and fast converting speed.
The light in Sodium Vapor lamp is from an atomic emission process. The mechanism of light emission in a sodium vapor lamp is simple and straight-forward. The filaments of the lamp sputter fast moving electrons, which hit the sodium atoms (vapor) causing the valence electrons of the sodium atoms to excite to higher energy levels and the electrons thus excited relax by emitting the characteristic monochromatic bright yellow light (589nm). It works by electric discharge. Although sodium vapor lamps produce much higher light output (about 90 lumens/watt) they cannot be used in lighting applications where color-rendering property is very crucial. This is because most of the light emitted from a sodium vapor lamp is concentrated in the yellow part of the visible spectrum (around 580-590 nm).
Trees might be the source of the ultimate green power and researchers have figured out a way to plug into the power generated by trees. Scientists have found out that plants can produce electricity. It can pack up to 200 millivolts of electrical power. A millivolt is one-thousandth of a volt. A big Maple trees generated steady voltage of up to a few hundred millivolts. Powering a circuit, however, required a much higher voltage. To extraxt power from trees and convert it into useful energy, experts built a boost converter capable of picking up as little as a 20 millivolt output and storing it to produce a greater output. By hooking up to a tree using electrodes, the custom-built device was able to generate an output voltage of 1.1 volts, enough to run low power sensors.
