INTRODUCTION Investigations are the processes that will be used to describe both criminal investigation and crime scene processing distinctions between criminal investigations and crime scene. Crime scene requires strict scientific methodologies such as collections procedures and testing protocol‚ whereas criminal investigation has less of hard science character and relies more on the experience and skills of the investigator rather than rigid scientific protocols and procedures. Evidence is a

MATH INVESTIGATION 4.2 FACTORIZATIONS on the Math Investigator determines if a number is prime or composite. If a number is composite‚ it prints all its factors‚ the number of factors‚ and its prime factorization. The numbers 1‚ 2‚ 4‚ and 6 have 1‚ 2‚ 3‚ and 4 factors‚ respectively: 1 has only 1 as a factor; 2 has 1 and 2 as factors; 4 has 1‚ 2‚ and 4 as factors; and 6 has 1‚ 2‚ 3‚ and 6 as factors. These factors are illustrated by the rectangles shown here. Starting Points for Investigations

Solutions of starch and amylase were held at selected temperatures by various methods of temperature control. Once

Investigation on the effects of Temperature‚ pH levels‚ and Enzyme Concentration on the reaction rate of the Decomposition of Hydrogen Peroxide by Catalase The purpose of this investigation is to figure out how temperature‚ pH‚ and enzyme concentration affect the reaction rate of an enzyme. It’s important to understand how certain factors affect enzymes because of their crucial role in the metabolic processes of life. Enzymes lower the activation energy necessary for a chemical reaction to

COMBUSTION AND FIRE INVESTIGATION There are many different types of fires and it can be quite difficult to establish what may have started the fire in the first place. Fire investigation is an important process that attempts to establish the cause of the fire and whether a criminal act has taken place. The National Fire Statistics in the UK compiled by the Home Office states that 25% of fires are electrical in origin but this does not tell the whole story. The statistics are compiled from fire

Dana Calderone Responses of Enzyme Activity from pH and Concentration Abstract Enzymes are the key to many of the chemical reactions that our bodies depend on to live. Without enzymes‚ we would not exist. These biological catalysts speed up the reactions as well as reduce the amount of activation energy needed to complete the process. Knowing how important enzymes are to us‚ it is important to realize what they require to function. They need select conditions and rates to work right. These conditions

Enzyme Catalysis Introduction: Enzymes are produced by living organisms as proteins. These enzymes perform as catalysts to bring about a chemical reaction. In fact‚ most reactions are catalyzed by enzymes during reactions in the cell or in the human body. A catalyst that enzymes pose ad are by definition substances that are capable of initiating or speeding up a chemical reaction. Catalyst are not a necessity during a chemical reaction‚ they are just used to speed up a chemical reaction. This event

Some reasons that a homicide investigation starts at the primary crime scene is mainly because the police are usually called to this location by the person who discovers the body‚ or‚ a witness to the crime‚ but it could also in some cases even be the victim. In homicide cases‚ the location where the body is discovered hold a great deal of physical evidence and serves as a starting point for the beginning of an official investigation. At this point it is safe to say that it is important to assume

Criminal Investigations The method of inquiry is the way that an investigator or detective gathers information about a specific case. There is several different method of inquiry such as evidence collection‚ witness and victim statements‚ and information stored in public and private databases. The methods of inquiry are used to figure out what happened at a particular crime scene. A criminal investigator is trying to establish the who‚ what‚ where‚ when‚ why‚ and how of the crime. During this process
