PIRATES OF SILICON VALLEY The film was a great watch especially for techno-geeks like me. Not that I have each and every gadget ever made by man‚ but we can say that I am easily amazed and curious about a lot of things including computers and such. Pirates of Silicon Valley shows a part of the history of computers‚ how it develops‚ and a part of the rivalry between the two main competitors of this age‚ Apple and Microsoft. The film shows how Steve Jobs of Apple Computers is easily deceived

Introduction The reaction rate of a chemical reaction is determined as the change in the concentration of a reactant or product over the change in time. [1] The rate of a reaction is determined by experiment. Many factors influence the rate of a reaction: the nature of the reaction‚ concentration‚ pressure‚ temperature‚ and surface area‚ presence of catalyst and intensity of light. [2] For a chemical reaction‚ the rate law or rate equation is a mathematical expressed equation that links the reaction rate with

Publication No. 91860 Rate of Reaction of Sodium Thiosulfate and Hydrochloric Acid Rate Laws Introduction The purpose of this demonstration is to investigate the effect of sodium thiosulfate concentration on the rate of reaction of sodium thiosulfate with hydrochloric acid. The reaction‚ which produces solid sulfur‚ will be followed by measuring the time needed for the reaction mixture to become opaque. The results will be analyzed graphically to determine the order of reaction— the mathematical relationship

Grignard reaction Abstract: In this laboratory‚ triphenylmethanol was synthesised from reacting benzophenone and bromobenzene using Grignard reaction. As the reaction was to set up to produce a Grignard reagent and then recrystallize it to obtain pure sample. The percentage yield obtained was 55% and its melting point was 161 co which is within the literature value 160-163 co. In addition to that the IR spectroscopy confirmed the molecule structure to be triphenylmethanol. Introduction: The Grignard

Defence Mechanisms in Guajiro Personality and Culture LAWRENCE C. WATSON ANALYSIS Defence is all efforts of the ego to render inoperative and instinctual wish or impulse. The instinctual object choice produces neurotic anxiety because it clashes with the superego‚ which arises from the internalisation of the parent’s moral values. Defences protect the individual from experiencing anxiety either by detaching the forbidden wish from conscious awareness or by distorting or falsifying its true meaning

The role of price mechanism in a free market economy or capitalism! The price system functions through prices of both goods and services. Prices determine the production of innumerable goods and services. They organise production and help in the distribution of goods and services‚ ration out the supplies of goods and services and provide for economic growth. Let us analyse the role of prices in all these spheres. (1) What and How Much to Produce: The first function of prices is to resolve the problem
