of well known environmental contaminants‚ such as dioxin‚ PCBs and DDT‚ can affect hormone levels. Hormones are produced by the endocrine system as regulators of biological function in target organs. Because hormones play a critical role in early development‚ toxicological effects on the endocrine system often have an impact on the reproductive system. The term endocrine disruptor is used to describe chemicals that can mimic hormones and may either enhance or counteract their effects. It has been

Physio-EX Blood Analysis: Computer Simulation Introduction In this lab five blood tests will be performed: hematocrit determination‚ erythrocyte sedimentation rate‚ hemoglobin determination‚ blood typing‚ and total cholesterol determination. A “hematocrit refers to the percentage of red blood cells (RBC’s) in a sample of whole blood. Since the function of red blood cells is the transport of oxygen to the cells of the body‚ the higher the hematocrit‚ the more red blood cells are available to carry

Components of a Computer System A computer system consists of both hardware and information stored on hardware. Information stored on computer hardware is often called software. The hardware components of a computer system are the electronic and mechanical parts. The software components of a computer system are the data and the computer programs. The major hardware components of a computer system are: Input devices: Keyboard‚ mouse‚ scanner‚ digital camera and joystick. Peripheral device used

INTRODUCTION Computer systems are a very important part of our world today and are seen almost anywhere. It has got to that stage where computer systems are a part of pretty much all we do. In this same sense‚ anybody who has no computer knowledge whatsoever would be regarded as an illiterate in full years to come and with this regard; we can say that not having any knowledge of computers is like not attending a school at all. This article explains how and where computer systems are important to

Military Computer Systems History : By Bilal At the outset of computer engineering development in the USSR in the 1950s the main attention was concentrated on the creation of computers which could solve complex mathematical problems. Computers then were stationary and intended for successive or batch problem solution irrelatively to the real time and dynamic parameter changes. Later the machines formed the most widespread class of universal computers for various applications. By the late

October 2012 Evaluating a Computer System Judging the effectiveness of a computer system has taken on a new dimension in the past few years‚ if for no other reason than the wide range of computer systems from which the user can select. It is‚ therefore‚ important that we investigate the criteria that should be considered in making this important decision. Probably the obvious criterion to be considered when one purchases a computer system is speed. The value of a computer is directly related to its

"The Use of Computers in the Educational System" The processing and uses of information are undergoing an unprecedented technological revolution. Not only are machines now able to deal with many kinds of information at high speed and in large quantities but also it is possible to manipulate these quantities of information so as to benefit from them in entirely novel ways. This is perhaps no where truer than in the educational system. The computer makes the individualization of instruction
