Why You Should Spay Your Female Dog? Female dogs can get all kinds of health issues when the female dog isn’t spayed by a certain age. I know some people choose to impregnate their dogs and have puppies to sell. After about five years it is best to spay your dog, if you do not plan to have puppies. If of course, you have no plans of your female having puppies at all, please spay as soon as you are able too. Female dogs five plus years not spayed can have all kinds of health issues. They

the Arms of an Angel” and there are dogs and cats sitting behind a closed kennel door looking at the camera with sad eyes. This breaks my heart every time I see this commercial or hear the song playing on the radio. There are many millions of animals that are unloved, neglected and abandoned in shelters each year because people do not participate in getting their animals’ spayed or neutered or the animals are over bred for profit. Animal overcrowding in shelters is only one reason of many as

to a part of the system that is at elevated pressure. The sample is then transported to a separator by the flow in the system.      After the column the separated compounds enter the detector, which measures a physical or chemical property of each, now relatively pure, compound and creates a proportional electronic signal. By calibrating with a standard mixture of known compounds, the nature of the compound in the

Gulf War Syndrome The Gulf War Syndrome was identified after the Gulf War in 1991. Thousands of troops from the US, British, and Canadian developed symptoms after the war. This Syndrome has been researched since the end of the Gulf War and still not all the answers have been found. Not only have thousands of troops suffered from this syndrome, but also their families have developed some symptoms related to this syndrome. It is important to inform our nation of this new disease because there

Effects of Temperature, pH, Enzyme Concentration, and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes, proteins that act as catalysts, are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes, the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol

Kinetics of Hydrogen Peroxide February 22, 2007 Chem. 1130 TA: Ms. Babcock Room 1830 Chemistry Annex PURPOSE OF THE EXPERIMENT Kinetics of Hydrogen Peroxide The major purpose of this experiment is to determine the rate law constant for the reaction of hydrogen peroxide and potassium iodide. In this experiment, the goal will be to try to measure the rate law constant at low acidity, since at low acidity, anything less than 1.0 x 10-3M, the effect of the hydrogen ion is negligible. To calculate

The Leukart reaction is 2-step with lower yields and requires chemical apparatus. There are also two synthetic methods which proceed directly from safrole rather than through isosafrole. The first is the Ritter reaction which goes through the intermediate N-acetyl-MDA. The Ritter reaction is time-consuming, requires

An enzyme is a biological catalyst. It speeds up a reaction by lowering the activation energy required to start the reaction. It speeds up a reaction, but remains unchanged unless certain limiting factors are introduced. It is composed of polymers of amino acids. An enzyme has an optimum pH and temperature. When an enzyme is at its optimum conditions, the rate of reaction is the fastest. In their globular structure, one or more polypeptide chains twist and fold, bringing together a small number of

Multistep Synthesis of Tetraphenylcyclopentadienone In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing compounds. There was a total of three steps that led up to the synthesis of the final product, tetraphenylcyclopentadienone. The first step of the experiment was the condensation of benzaldehyde to yield
