The Investigation of Serial Killings Kennedy Collins CRJU_ 101_ SEC 01 Dr. Tracy Tolbert Introduction This study examined of dysfunctional family structure on homicidal behavior patterns. Using qualitative method case-content analysis‚ the found that several correlates between family dysfunction‚ harsh parenting‚ and antisocial disorder; integrate to effect social outcomes that led people to serial killings. This study uses various methods such as‚ case studies‚ face to

Crime scene investigation requires the handling all types of potentially hazardous material‚ from blood and other physical evidence collected at the scene to the chemicals and other materials used by technicians as they perform their jobs. Failure to follow established safety and health procedures regarding the handling and disposal of hazardous material exposes crime scene technicians and others to a variety of risks. Technicians collecting evidence at crime scene must handle a range of biological

The Method of Scientific Investigation Scientific investigation in my own words is when someone breaks down a problem to find a solution scientifically‚ but there can be more to it than just investigation a problem scientifically. Thomas Huxley explains scientific investigation in more depth in his “The Method of Scientific Investigation” essay‚ what is he trying to say in this passage? It could be many things‚ it could be nothing or it could be something‚ we’re basically trying to find out what

hydrogen peroxide and potatoes (enzymes)? Introduction The enzyme used for this experiment is Catalase. Catalase is inside mostly any living organism which uses oxygen. Its job is to break down hydrogen peroxide‚ into oxygen and water. (Formula) 2H2O2 ---> 2H2O + O2 (lab manual). There are limiting factors which if altered‚ can alter the procedure of the reaction‚ such as temperature‚ pH‚ and the concentration of either the enzyme or the substrates. Enzymes are specialized class of protein

In solving a crime‚ a crime scene is usually imperative to the investigation. Documenting a crime scene helps to establish some of the evidence or rather investigative leads which may help solve the case. Additionally‚ the leads found in the crime scene can help solve the case or determine what happened. Poor scene documentation can prompt unacceptable evidence in a courtroom‚ or missed evidence that may permit a victim to escape with a crime. Photography is important during the documentation of

Abstract The main goal of the enzyme kinetics experiment was to see how the phosphatase-catalyzed hydrolysis of p-nitrophenyl produced p-nitrophenol in the presence of phosphate and fluoride ion inhibitors of various concentrations. The calculated Km constant was found to be 0.22 for all reactions. The Vmax values for each inhibition ion were 0.00986 for the phosphate ion and 0.00436 for the fluoride ion. The inhibitor constant‚ Ki‚ was determined to be 0.0967 for the phosphate ion. The inhibitor

In this lab the peroxidase enzyme is tested in a dormant avocado seed as well as an avocado seed undergoing the process of germination. A gas pressure will be used to test the seeds and see if the peroxidase enzyme is present in either of the seeds. A catalyst is very similar to track spikes. Spikes increase a runner’s speed‚ as a catalyst speeds up the chemical reaction time in a plant. Neither the catalyst nor shoes are changed in these actions. Enzymes are macromolecules that act like catalysts
