The biochemical importance of water Sam Ellick 13/11/2010 Water otherwise known as H2O is a necessity for life to exist. It has many unique features compared to other molecules of its size. For example solid ice is less dense than liquid ice‚ which ponds and lakes freeze from the top down. This is important in insulating the aquatic life in the winter. This essay however will be looking at why water is so important in biochemical terms. Its shape Water‚ as its formula H2O suggests‚ consists

One pioneer who was instrumental in moving organization theory to the contingency approach was Joan Woodward‚ who studies the effect of technology on the organization. Woodward found that many variations in organization structure were associated with differences in manufacturing techniques. As Woodward pointed out: "Different technologies imposed different kinds of demands‚ and these demands had to met through an appropriate structure. Commercially successful firms seemed to be those in which function

on the other hand‚ is used so that information can be transmitted through the channel with a specified reliability. Information theory answers the two fundamental questions in communication theory: what is the limit of data compression? (answer: entropy of the data H(X)‚ is its compression limit) and what is the ultimate transmission rate of communication? (answer: the channel capacity C‚ is its rate limit) . Information theory also suggests means which systems can use for achieving these ultimate

CHAPTER 1 INTRODUCTION 1.1 What is thermodynamics? Thermodynamics is the science which has evolved from the original investigations in the 19th century into the nature of “heat.” At the time‚ the leading theory of heat was that it was a type of fluid‚ which could flow from a hot body to a colder one when they were brought into contact. We now know that what was then called “heat” is not a fluid‚ but is actually a form of energy – it is the energy associated with the continual‚ random motion of the

predicted using its neighbors. A typical image/video transmission system is outlined in Figure 1. The objective of the source encoder is to exploit the redundancies in image data to provide compression. In other words‚ the source encoder reduces the entropy‚ which in our case means decrease in the average number of bits required to represent the image. On the contrary‚ the channel encoder adds redundancy to the output of the source encoder in order to enhance the reliability of the transmission. Clearly

Absolute entropy is entropy calculated relative to the absolute reference point determined by the third law of thermodynamics. Absolute humidity (specific humidity or humidity ratio) is the mass of water vapor present in a unit mass of dry air; that is‚ it is the ratio of the mass of water vapor to the mass of dry air in atmospheric air. Absolute pressure is the actual pressure at a given position and it is measured relative to absolute vacuum (i.e.‚ absolute zero pressure). Throughout this
