examination in terms of detecting and identifying bloodstain pattern analysis, analyse ballistics and fingerprints. Guns are known to produce a distinct bloodstain pattern, which is the High-Velocity Impact Spatter where tiny droplets are caused by blood travelling at high speeds. By using this knowledge that investigators have about guns, they can track down and reconstruct the crime scene using biological examination. Additionally, gunshots leave different types of evidence behind, depending on the

forms of heart disease; the most common is caused by the blockage of coronary arteries, which allow blood to flow to the heart, and increased blood pressure called coronary artery disease (U.S. National Library of Medicine, 2015). Performing a blood lipid profile will determine one’s risks level for developing heart disease. The lipid blood profile collects the overall results of lipids in the blood, such as total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density (HDL) cholesterol

Next, wash your hands, prepare the work station, and set up all the equipment that is necessary to perform the process. Then

changing of fluid pressure in the circulatory system is defined as blood pressure. Blood pressure is the measured as the force per unit area applied on the walls of the blood vessels, especially the arteries. Systole is the peak pressure produced by the contraction of the left ventricle, which is followed by a fall in pressure, termed diastole, when the left vernicle relaxes in preparation for the next contraction. The standard blood pressure is measured at 120/8 mmHg, where the top represents the

Blood pressure fluctuates throughout the day and normally decreases during nighttime. Patients can be classified as either dippers or non-dippers dependent on how much their blood pressure decreases over the course of the night. Dippers are considered patients whose blood pressure reduces by at least 10% during the night in comparison to their daytime readings, a dipping pattern is desired. The goal blood pressure for nighttime is <0.005). Nondipping blood pressure is a common manifestation associated

Blood is the necessary cornerstone of all animate life on the planet Earth. As we know it is what keeps us alive and makes our bodies work, though, in the novel Dracula, author Bram Stoker puts a spin on what we know about blood and how it can be perceived.

In result of the gang violence and the continuation of the initiations across the country has led to a vast uprise in crime and homicide since the start of the groups. I will begin this paper by explaining what a “gang” is and its effects on the demographics of its community and the effect it has on society along

blood cells) have a constant interaction, but this interaction increases with elevated cholesterol levels. As the cholesterol levels increase, the monocytes begin to attach onto the endothelium, where they are transformed into macrophages. These macrophages begin to oxidize the LDL and they become toxic to the endothelium which leads to platelet adhesion and aggregation and fibrin deposition. The macrophages begin to ingest the oxidized LDLs transforming them into foam cells, which begins the formation

In Lorca’sconflict themed play;Blood Wedding , symbolism is a dominating literature technique that forebodes the significant events that occur. The protagonist of the play, Leonardo, is seen to have a rebellious attitude towards society. The horse is perceived to be a symbol of occurrences that foreshadows his destiny, which is his death caused by his desire to attain individuality in the repressive society he lives in. This is especially prominent in the morbid lullaby sang by his mother and wife

Blood Pressure Blood Pressure is the pressure of circulating blood on the walls of the blood vessels. Blood Pressure usually refers to the arterial pressure in the systemic circulation. Blood Pressure is expressed in terms of the systolic pressure over diastolic pressure and is measured in millimeters of mercury. Blood Pressure can be influenced by things that we can’t do anything about like race, age, and gender. Normal Blood Pressure is less than 120 over 80 (120/80), Prehyprotension blood

another group of heros(white blood cell) and I think I need to get myself a sidekick so that I can teach him my ways to fight become strong because it is almost my final day as a white blood cell.

The play starts as blood representing honor and how Macbeth is a hero but soon changes to symbolize

The splatter of blood is different from the splatter of other liquids because blood has a different consistency than regular liquids. Blood is analyzed in many different ways, including its shape and the location of the blood stains. “Analysts examine the size, shape, distribution and location of the bloodstains to form opinions about what did or did not happen” (“Bloodstain Pattern Analysis”). The length of blood splatter is calculated based on the height of where the blood was dropped and the amount

1.1 Blood-Brain Barrier The Blood-Brain Barrier (BBB) is described as a dynamic interface between the peripheral circulation and the central nervous system. It functions as a physical and metabolical barrier between the nervous system and the circulating blood and is important for neuronal microenvironment, protection against in the peripheral blood circulating toxic molecules and to prevent neurotransmitters to escape into the general circulation. The barrier function was first discovered in 1913

types of blood vessels. The Structure and Functions of Blood Vessels ARTERIES The walls of arteries contain smooth muscle fibre that contract and relax under the instructions of the sympathetic nervous system. The functions of the arteries are: transport blood away from the heart and transport oxygenated blood only. Arteries have four different parts, which are; lumen, endothelium, smooth muscle and connective tissue. LUMEN=the lumen of arteries is relatively narrow to maintain high blood pressure

Prior to administrating a blood transfusion using the checklist that is provided by the work place such as Queensland Health, the Enrolled Nurse has the responsibility to ensure each item on the check list has been completed (Darling Downs Hospital and Health Service (DDH&HS), 2009).

Using the checklist for the transfusion of platelets the enrolled nurse will take note of

A word that comes to mind when I watch the movie, Blood in Blood Out is “raza.” To me this word symbolizes family, close friends, and brotherhood. For instance, the film has moments of great happiness with family, but also moments of despair with life. The movie Blood in Blood out has made me feel empathy with the Hispanic culture, the experience of gang violence, and the film reminds me of pain. This film involves Hispanic culture that relates to my heritage when the movie displays familia gatherings

Ask the average American to name a gang they are familiar with and chances are the response will be either the Crips or the Bloods. Over four decades ago, African American youth founded these gangs after many years of oppression, marginalization, and institutional racism. The Crips and the Bloods, who originated from neighborhoods of Southern California, have now spread across the nation with a presence in thirty-two states. They changed the American landscape forever. In 1969, a young man in
