Abstract Cold case investigation is a growing concern due to increased numbers of unsolved cases and pop culture appeal. This paper will walk you through what a cold case investigation is‚ how one begins‚ and factors such as the use of volunteers can effect the outcome of a cold case investigation. Each year the number of unsolved cases in the U.S. goes up‚ but with limiting funding and lack of manning something has to be done to keep the numbers down. A dedicated cold case unit is the best answer

Ben Groesbeck Stearns Intro to Criminal Justice October 2‚ 2011 Arson and Fire Investigation What is arson and fire investigation? Arson and fire investigations are conducted to find out whom or what was responsible for creating a fire. It is critical that we know why a fire was created so you can prevent it from ever happening again and also to determine what accelerants were used if any. In this paper I will go into depth on what it takes to become an arson or fire investigator. How do

Plan of investigation How did advancements of aviation during WW2 led to modern civil travel? This investigation will look to see how the advancements of the modern airplane during WW2 helped to shape civil travel today. This investigation will be looking mainly at secondary sources like sources of the planes themselves and histories or company who specialize in the modern aircraft‚ primary sources will be used only to tell of the handling of the plane themselves. This investigation will look

Paper Cone Investigation Lisa Han 10MF Design Research Question: This investigation will determine how the sector sizes of the piece of the filter paper affect the terminal velocity for the cone to fall. The following will be kept constant meter ruler‚ stopwatch‚ and filter paper. Hypothesis: ‘If the sector size is the increase‚ then the terminal velocity will decrease.’ The reason is that if the sector size is bigger‚ the surface area of the cone will become smaller. If the surface area

The Effect of Exercise on Heart Rate The aim of this investigation is to find out how different types of exercise can affect my heart rate. To measure and record my heart rate‚ I am going to undergo an experimental test. I am going to do 3 different types of exercise: walking‚ light jog and lastly hard running. First‚ I will draw out a table to record my results‚ and then I will measure my resting heart rate for one minute. To make the experiment as accurate as possible‚ I will

BIOLOGY HSC NOTES MAINTAINING A BALANCE • Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates. Enzymes are protein molecules that allow the body to engage in chemical reactions‚ such as metabolism. There activities can be catalytic (being able to control the rate of either increasing/decreasing chemical reaction) Enzymes have a specific shape‚ and this shape must be intact‚ otherwise the effectiveness

The Effect of Temperature on the Enzyme Catalase Stephen Francis Biology 183 Abstract This experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at room temperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this experiment proved

DNA almost immediately transformed the American Criminal Justice System. Law Enforcement‚ District Attorneys‚ Defense Attorneys‚ Criminal Court and Family Court all work with DNA on a daily basis. DNA that can be utilized in a criminal investigation may be collected from a crime scene in many different forms: skin tissue‚ hair‚ blood‚ semen‚ saliva‚ vaginal fluid‚ anything that may be collected from a human that may contain cells can be utilized and tested for DNA. DNA testing is the most

certain environmental factors affect the enzyme activity rate. For the first experiment‚ where we tested the increase in concentration of enzyme with the substrate‚ we found that higher concentration of enzyme increases the rate of reaction of the enzyme. This is because more enzyme molecules are present‚ which allow more substrate molecules to get into the active sites of the enzyme (Sattler W& Esterbauer H). When calculating the absorbance of different enzyme concentration‚ it was noticeable that
