For the past two decades, lasers have been used to measure distance without having to physically touch the area or things being measured. Laser measurement is capable of very precise and quick distance measurements. Lasers have been used in military targeting, criminal investigations, and sports. As research has progressed, the size of laser measuring devices …
The LRAD or the long range acoustic device that has been developed by American Technology Corporation is capable of emitting a maximum of 151Db sound within 30 degrees of where the device is pointing. This device can be used as a combatant deterrent weapon or crowd-control device by emitting sounds that are painful to the …
An oxygen generator is a device that produces oxygen on demand, usually through the use of inorganic reactions. There are several types of oxygen generators but each depends on thermal reactions to produce oxygen. This causes the generator to become very hot, between 500 and 1,200 degrees Fahrenheit, and can present a serious fire hazard …
The biuret test is one in which a researcher can determine whether a mixture has peptide bonds in it or not. By using the biuret test, in seconds an individual knows if they are there. Once they know that the peptide bonds are, in fact, there, they can then attempt to measure the amount of …
Humidity sensors (hygrometers) measure and report the air’s relative humidity. They are used in homes, wine cellars, and working environments that that are so humid that they negatively impact working conditions. Humidity sensors are also used in vehicles, industrial HVAC systems, and meteorological stations to help in the predicting and reporting of weather conditions. How …
Neurons communicate by sending electrical signals throughout the body. The exact process is an electrochemical one and the speed in which neurons communicate is so fast that seeing someone drop out of someone's hand and trying to grab for it–a process that requires the image to get into the brain, processed and then a signal …
While many of us labored to learn geography in school, we always wondered why it mattered. Here are some reasons why a sound understanding of geography is more important today than ever before. Politics We live in a world that is shaped by the political climate in various locations around the globe. In order to …
An acrylic adhesive is a resin-based adhesive that is comprised of acrylic or methylacrylic polymers. It is rather complicated to produce acrylic adhesives as they must be formed into a polymer, suspended in a catalyst, and cured. Acrylic adhesives are very strong and efficient at bonding multiple objects together. They are resistant to sunlight, not …
Photosynthesis is the process that plants, some bacteria, and some animals use to convert light energy and other sources into sugar and other essential proteins that they need to survive. This article will go over how photosynthesis works and the many different aspects of this process. We will talk about photosynthetic membranes, light reactions, solar …
Ocean currents are one of the main factors that affect climate. Other factors are proximity from the equator, distance from the sea, direction of prevailing winds and relief (mountains). But, for the most part, ocean currents act as one of the most important factors that influence the climate. And the reason why is because a …
