INTRODUCTION
INTRODUCTION Cardiac Location and Structures The heart is the driving force of the circulatory system, contracting about 70 times/minute to pump an adequate volume of blood with sufficient pressure to perfuse all body organs and tissues. The muscular organ, about the size of a clenched fist, weights from 300 to 400 g. It is located within the mediastinum of the thoratic cavity, above the diaphragm and between the lungs. This location subjects the heart's activity to influence from all pressure ...

Metallic Conductor
Metallic Conductor Determination of r for a Metallic Conductor Aim: To determine the resistivity (r) of a given sample of wire Introduction: Physical factors that affect the resistance of a conductor are length, cross sectional area and a constant that depends upon the material called the resistivity. The resistance per unit length is the same all along a uniform wire so if the resistance of different lengths of a wire is found out, the resistivity can be calculated. Resistance of a material, R ...

Investigating The Factors Which Affect The Resistance Of A Piece Of Pu
Investigating The Factors Which Affect The Resistance Of A Piece Of Putty resistance Of a piece of resistance putty Planning: This investigation is designed to look into the resistance of different materials, in this case, resistance putty in the form of wires, and their conducting capability in different shapes. We must bear in mind though that different thickness and length of the putty used to make up the wire itself will affect the electric conduction capability. Therefore, the factors are; ...

Ultrasonic Radar For A Home PC System
Ultrasonic Radar for a Home PC System One of the fastest changing and most expensive fields, is that of technology. Our computers, printers, modems, and much more is being outdated faster than anything else in the world. Just as we buy a new computer that does what we want, the industry comes out with a new option on a smaller and better computer. There seems to be so much changing that unless we invest our life savings into technology, we are considered obsolete like our computers. What used to...

Feminine Traditions
Feminine Traditions In our society women are often pressured and conditioned to conform to traditional feminine standards. In the past fifty or so years women have begun to find modes of resistance against these cultural constraints. In this essay I will cover Bartky's essay Skin Deep, she theorizes about theproperly feminine subject, the definition of the body, disciplinary practices and how to resist. Bartky theorizes about the properly feminine subject by stating that it is to embody th...

Bipolar Junction Transistor
Bipolar Junction Transistor The objective of this lab is to introduce the Bipolar Junction Transistor (BJT). A BJT is a three terminal device composed of an emitter, base, and collector terminals. In this lab we will introduce two major types of BJT's : npn and pnp. The first, npn, has an n-type emitter, a p-type base and a n-type collector. On the other hand the pnp has a p-type emitter, a n-type base, and a p-type collector. Also the transistor consists of two major pn junctions, the emitter-...

Wind Power
Wind Power annon The wind turbine, also called a windmill, is a means of harnessing the kinetic energy of the wind and converting it into electrical energy. This is accomplished by turning blades called aerofoils, which drive a shaft, which drive a motor (turbine) and ar e connected to a generator. It is estimated that the total power capacity of winds surrounding the earth is 1 x 1011 Gigawatts (Cheremisinoff 6). The total energy of the winds fluctuates from year to year. Windmill expert Richar...

Motion-Type Sensors
Motion-Type Sensors The purpose of this lab was to gain an understanding of the operation of motion-type sensors such as a potentiometer, encoder, and tachometer. In the course of this experiment we learned how to properly calibrate this equipment and perform data acquisition on it. BACKGROUND: The most commonly measured physical quantities are position and velocity. This is because it is important to know how a mechanism moves in order to control its behavior. Rotary sensors are often employed ...

North Korea
North Korea One of the misconceptions about the North Korean prisoner camps, where the extraordinary amount of brainwashing happening in them. The communists gave the American prisoners of war some reeducating. Brainwashing proved in the long run to be unproductive, but it did keep 21 Americans in camp. The American armed forces tried to find out what really happened with their own psychologists, but the information taken was inconclusive. Some of the POW's in the North Korean camps where corrup...

Civil Rights
Civil Rights The Reverend Dr. Martin Luther King Jr., in his book Why We Can't Wait, quite correctly named the civil rights struggles of the mid-twentieth century the Third American Revolution. Though it is most often attributed to the 1960s the civil rights movement found it's start in the decade before that, the ?peaceful 50s'. The civil rights movement actually started with legal battles before moving into the streets of American cities. The Supreme Court ordered the desegregation of schools ...

History Of Computers
History Of Computers Early Computational Devices Somewhere around 3000BC the first mechanical counting device created was the abacus. The abacus is still used today and, amazingly to me, with great speed and accuracy. In 1642 another mechanical device was created called the Pascaline (after Blaise Pascal, a famous French mathematician). The Pascaline used gears and wheels (counting-wheels) to perform the calculations. The interesting thing to note is that the counting-wheel design was used in ca...
