2002). A catalyst is usually a protein; however‚ some catalytic molecules counter this generalization. A discovery made in the early nineteen- nineties revealed that ribozymes‚ molecules made of ribonucleic acid (RNA)‚ act as a catalyst in the transformation of an RAN molecule. Scientists concluded from the new discovery that the informational molecule RNA may have once been able to function without proteins (Dousti‚ 1995). However‚ enzymes are strictly proteins‚ and thus are subject to denaturation

Coolant and cutting fluid management Contamination of coolants and loss of cutting fluid through chip waste is one of the most time consuming and costly situations for a company. That is where fluid management comes into play. There are many ways to fight contamination and fluid loss. Loss of cutting fluid and coolants through chip waste can be solved with a briquetter. A briquetter is a machine that compresses your chips and turnings into a briquette squeezing out ninety percent of your expensive

Water Balance of Berkeley‚ California and Terre Haute‚ Indiana Johnny L. Luckett Excelsior College Abstract This paper discovers the water budget for Berkeley‚ California in comparison to Terre Haute‚ Indiana. The two cities precipitation differs throughout the twelve month calendar year where many of the heavy precipitation months are totally opposite. Berkeley California’s winters‚ where the majority of rain occurs and Terre Haute‚ Indiana where the rainfall is observed as

A balance sheet‚ like a photo‚ provides a financial picture of a company on a given day and time. It categorizes all of a company’s resources as assets‚ all of its debts as liabilities‚ and all of the owner’s investments as equity. A company uses its assets‚ such as accounts receivable‚ inventory‚ and equipment‚ for manufacturing or purchasing products for sale or to provide a service. A company’s assets are financed by its liabilities (debt) and the owner’s equity (net worth). On a balance sheet

The relatively close pH levels of Tap Water‚ Spring Water‚ Flavored Water‚ and Seltzer Water. Introduction This experiment was performed to investigate the following hypothesis: The following four different types of drinking water (spring water‚ seltzer water‚ tap water‚ and flavored water) we test will relatively have the same pH level. Our group decided to test different types of drinking water to see if a pH level of tap water is comparable to other types of water. Many people believe

Sacred Balance‚ David Suzuki has attempted to overcome the doom fatigue’ so his ideas of conservation and environmental management do not become the monotonous endeavours of intimidation that many environmentalists employ. The extensive use of diagrams‚ quotes‚ anecdotes and statistics are utilised to create a holistic portrayal of our dependence on the environment‚ thus reinforcing Suzuki’s attitude that society needs to treat the planet as though it were sacred.

IP Proposal I. Title- Correction fluid from chalk II. Problem -how to make correction fluid from chalk dust safer? a.) Hypothesis - If this correction fluid won’t have any solvents/chemicals‚ then it won’t be harmful to the nose/body. b.) Objectives of the study -the objective is to create a safer correction fluid‚ to avoid it from being an inhalant. c.) Significance of the study -the significance of the study is to reduce the solvents and other chemicals that are harmful to the body when

properly. This experiment was conducted to determine if the reaction rate changes in response to a variation of acidic‚ neutral‚ and basic solutions. The experimental results indicated that the basic/high pH solution has a faster rate of reaction in the solution. Introduction Enzymes are proteins that catalyze and convert molecules into combinations of other molecules which is necessary for the functions of human life. These enzymes are affected in the presence of a high concentration of Hydrogen
