The understanding of blood spatter patterns is not a widely recognized forensic practice. Bloodstain pattern interpretation (BPI) is commonly used in murder investigations‚ but could be utilized in everything from simple assault to mass murders if the number of trained professionals increased. BPI can reveal critical information into reinventing a given crime scene. Everything from the number of blows‚ stabs or shots a victim was given‚ the movement that was undergone by the victim and assailant

Properties of Gases General Chemistry 1 Lab 5 Abstract: The purpose of this experiment is to examine the properties of several gasses‚ which were the products of a reaction‚ and examine the way the gasses react under certain conditions. These conditions‚ such as introducing a flame to the gas as well as oxygen and CO2‚ caused other reactions to occur. Hypothesis: If the gasses are correctly synthesized then there will be a clear reaction with the introduction of the flame‚ O2‚ CO2‚ Air

FORMAL REPORT ON HEAT CAPACITY RATIOS OF GASES ABSTRACT This report discusses an investigation of the heat capacities of Helium‚ Nitrogen‚ and Carbon Dioxide. To accurately determine experimental values for the heat capacity of each gas‚ the heat capacity ratio was calculated from measurements of the speed of sound in each gas. An apparatus designed to measure the wavelength and frequency of sound waves in each gas was used to determine the speed of sound as a frequency was passed through each

Bloodstain pattern analysis is the interpretation of bloodstains at a crime scene in order to recreate the actions that caused the bloodshed. Blood spatter analysis can tell the distance from the source of the blood to the pattern‚ the direction from which the blood impacted‚ the speed the droplet was traveling‚ the location of the point of origin‚ and even the movement of a bleeding individual throughout the scene. There are three basic types of bloodstains. The first type of bloodstains are passive

Introduction When the heart beats‚ it pumps blood round the body to give it the energy and oxygen it needs. As the blood moves‚ it pushes against the sides of the blood vessels. The strength of this pushing is your blood pressure. If the blood pressure is too high‚ it puts extra strain on your arteries (and your heart) and this may lead to heart attacks and strokes. Having high blood pressure (hypertension) is not usually something that you feel or notice. It does not tend to produce obvious signs

One can do this by increasing the oxygen-carrying capacity of blood by raising the Hgb concentration of patients with acute/chronic anemia. Each unit will raise the Hct by 3 to 4 percent unless there is continued bleeding. Background: Transfusion trigger based on the 10/30 rule‚ give 2 units. However‚ with the discovery of transfusion-related HIV and
