1. INTRODUCTION Have you been to the gas station this week? Considering that we live in a very mobile society‚ it ’s probably safe to assume that you have. While pumping gas‚ you ’ve undoubtedly noticed how much the price of gas has soared in recent years. Gasoline which has been the main source of fuel for the history of cars‚ is becoming more and more expensive and impractical (especially from an environmental standpoint). These factors are leading car manufacturers to develop cars

fuel saving techniques employed by drivers. "You can do a lot as far as saving fuel is concerned by taking certain steps‚" said Devendra‚ an auto expert. He advised that air filter should should be cleaned regularly for better flow of air into the combustion chamber for igniting the fuel better. "This step can easily save fuel‚" he added. Similarly‚ owners should go for regular cleaning of fuel filter for a proficient compel. He‚ however‚ admitted that vehicle owners have now become more aware as far

Spontaneous Human Combustion Spontaneous Human Combustion(SHC) pertains to the burning of a person’s body occurring without an outside source of ignition. The characteristics of SHC varies form different cases but most of the time evidences gathered are more likely show similar clues which we can relate to other SHC cases. Now‚ the evidences gathered are as follows; the victim is an elderly‚ the furniture around the victim stayed untouched‚ a part of the ceiling above the victim was damaged

Lab 5 Oxidation of an alcohol CHM2123 Introduction: Oxidation is a key reaction in organic chemistry. Oxidation of an alcohol can produce aldehydes‚ ketones‚ or carboxylic acids. One of the methods of oxidation is an aldol reaction through carbon-carbon bonds. The oxidation oxidizes primary alcohols to aldehydes and secondary alcohols oxidizes ketones. Tertiary alcohols are converted to the common oxidizing agents. Scheme 5.1: Aldehydes can be oxidized easily to carboxylic acids in aqueous medias

Abstract Alcohol consumption may be linked to syncopal events. The mechanism by which alcohol may induce syncope is not well understood. Impairment of the response to orthostatic stress may be involved. A growing body of medical evidence suggests that short-term alcohol consumption elicits hypotension during orthostatic stress because of impairment of vasoconstriction. These findings have implications for understanding of hemodynamic effects of alcohol and‚ in particular‚ for understanding
