Water is one of the world’s most important natural resources. It is an essential
part of life because it not only sustains life but it harbors many forms of it as well.
Therefore, it would be in one’s best interest to make sure this source does not become
contaminated and make it useless and harmful. There are several different organisms and
chemicals that can be produced that will harm other, and bigger, organisms.
A major component of the chemicals and organisms that emerge from contaminated
waters is nitrogen. Several organisms play different roles in the nitrogen cycle. The
nitrogen cycle occurs in bodies of water especially in those that have the necessary and
beneficial bacteria that break down any waste into nitrates that can be consumed by many
organisms. There are other harmful bacteria, however, that are denitrifying bacteria that
reduce nitrate into gaseous nitrogen that is not helpful to any organisms. The denitrifying
bacteria turn helpful nitrates into harmful ammonia and nitrites. Ammonia, which is a
form of nitrogen, harms organisms such as fish. Ammonia is also a major contributor to
prolific algae growth. Algae is a unicellular organism that grows off of a great supply of
water, light, and nutrients that can be found in bodies of water such as ponds. These
components come from the sun, the water, and nutrients that can be found in fish and
plant waste, minerals in the soil, etc.
Another harmful bacteria that is produced in stagnant water is purple sulfur bacteria that
use hydrogen sulfide that ultimately produces sulfur. This can be oxidized into sulfuric
acid. Sulfuric acid is a very strong mineral acid and a constituent of acid rain. Sulfuric
acid is a very harmful substance to...

- I) Introduction Robotic technology has enabled the US military to use autonomous robots (or unmanned systems, UMS) in modern warfare. In the war with Iraq, the US military sent 12000 ground robots at the end of 2008 (P. W. Singer). One of the most popular robots used in Iraq is the iRobot Packbot, an unmanned ground vehicle, which is capable of detecting and destroying improvised explosive devices. Exploiting robots in warfare can save lives of many human soldiers. Moreover, robots are faster, have longer endurance, high precision and immunity to chemical and biological weapons (Ronald Arkin).In the National Defense Act of 2001 the U.S....

- Industrial Robots and Manufacturing Automation Abstract Automation started out as an assembly line of workers doing the same repetitive task all day long. Some of the jobs were very boring, dirty, unpleasant, and possibly dangerous. After the introduction of the first robot in 1961, automation began to advance in ways people could only imagine. Each of the six basic styles of robot used in industry today were designed with different applications in mind. Some of the robots were designed for assembly, others are more suited for simple pick and place applications, while a select few are capable of carrying heavy loads over a large area....

- Robots always had a special place in mankind’s heart. There has always been an aura of mystery and discovery surrounding them. What is a robot. Wikipedia defines it as “an automatically guided machine which is able to do tasks on its own.” That is a good definition of a robot, but there are few exceptions too. The term “robot” was first created by Josef Capek. It was used by his brother Karel Capek in his play Rossum’s Universal Robots. The word literally means “work” in Czech. The science fiction author Isaac Asimov was the first person to use the word “robotics” in his short story "Liar!" One of the first robots was thought up by Leonardo Da Vinci.... [tags: Technology]

- Robots Webster’s New World Dictionary defines a robot as any anthropomorphic mechanical being built to do routine manual work for human beings. This term was popularized by the Czech dramatist Karel Capek (1890-1938) in his 1921 play Russum’s Universal Robots (R.U.R.). The term has been used in fiction to describe self-controlling machines that resemble human beings. This concept has been the basis of stories starting centuries before, but has become popular due to the writings of science fiction writers and movies.... [tags: Papers]
