Spattered blood is a random distribution of bloodstains that vary in size that may be produced by many mechanisms. The size and quantity of spatters produced by a single mechanism vary significantly. The amount of available blood and the amount of force applied to the blood affect the size range of spatters. Spatter is created when sufficient force is available to overcome the surface tension of the blood. The amount of force applied to a source of blood and the size of the resulting spatter vary considerably with gunshot, beating and stabbing events. The size range of spatter produced by any one mechanism may also vary considerably. Impact spatter that is associated with gunshot may produce minute spatters of blood less than 0.1 mm in diameter that are often referred to by analysts as most like dispersions. This mist-like …show more content…
The size range is dependent on the quantity of available blood, the caliber of the weapon, the location and number of shots and impeding factors, such as hair, clothing, etc. Impact spatters of this type is most commonly associated with gunshot, but may also be produced in cases involving explosions, power tools, high speed machinery injuries, and high speed automobile collisions. Forward spatter, which is associated with an exit wound, no forward spatter is produced in cases where the projectile does not exit the body. The mechanism that creates impact blood spatter will create a variety of sizes of bloodstain that would fit into the categories with beating and stabbing events, as well as spatter produced by expiration blood. Impact spatter associated with beating and stabbing events generally exhibits a size range from 1 to 3mm in diameter. Mechanisms other than beating, stabbing and gun shots, would be the expiration of blood and satellite spattering. They may also produce spatters in the same size range of less than 1 to
Besides the nurse’s “bender” comment, and Mrs. Fender’s social history, Tim suspects alcohol abuse based on many of his physical exam findings. Name at least three signs and/or symptoms that point to alcoholism, and briefly explain why each sign/symptom may occur. • Jaundice: The result of liver damage. The yellow color comes from the pigment found in bile, a digestive juice made by the liver.
The shots that were fired were too fast to just be one person because the bolt action rifle that was supposedly used couldn’t fire that fast even professional shooters that we tested couldn't do that and the shots that were fired came out in less than 10 seconds. The text says that there was also a police killing the same day too but the two eyewitness descriptions were
Two bullets fired by Eric Harris 's semi-automatic weapon hit Anne One pierced her chest the other, her spinal cord. She survived,
Get killed by airborne stones is what that is. But it can only be one person, so they pick strips of paper and the person with the black dot on their
In this zone, in light of the high temperature, almost the majority of the matter present is vaporized to shape a gas at to a great degree high weight. A sudden overpressure, i.e., a weight far in overabundance of climatic weight, proliferates far from the focal point of the blast as a stun wave, diminishing in quality as it ventures. It is this wave, containing the majority of the vitality discharged, that is in charge of the significant part of the dangerous mechanical impacts of an atomic blast. The subtle elements of stun wave engendering and its impacts change contingent upon whether the burst is noticeable all around, submerged, or
These bullets pierced the skin, ripped the tissue, and shattered the bone, while a smooth bore bullet just broke bones and tore through tissue. These bullets were much more dangerous and fierce than others. Upon impact the bullet cut through the skin, flattened and/or splintered as they hit the target. Some soldiers even notched their bullets to ensure they would spread when they hit a person. Often when a soldier was hit by one of these bullets, the limb had to be amputated.
Some from the crowd yelled out “damn your bloods-why don’t you fire.” Right after four soldiers fired one after another. The mob ran away except the three men who instantly died in which Mr. Gray was one of those. One more dead and three dangerously wounded and fore slightly
Blood contains both slid and liquid form in our body and becomes a jelly like substance once it exits the body. A blood spatter deeply understands the proportion of blood and its various types. An analyst can describe how the blood came out of the body depending on the type of injury which took place. Blood can be looked like a flow, drip, spray, spurt or a gush (http://www.forensicsciencesimplified.org/blood/principles.html). Blood describes its velocity by its stains.
This paper is based on an interview that I conducted with my maternal grandmother who I currently live with. It is surprising to me that I thought I knew what hers responses to my questions would be because of my visit to Greece. Greece currently has a socialist system of medicine, much like many of the countries of the world, and very much unlike our current system of medicine in this country. Needless to say, I was wrong. I had no actual idea what she was about to report to me in our interview.
In 1791, a musket ball could take off at around 700 mph. The musket ball itself was a fairly large, heavy and blunt projectile, causing major damage on impact. It could shatter bones, break blood vessels, and cause loss of limbs completely. Modern bullets take off anywhere from 1700 mph or higher. They weigh less rely on their speed to do most of the damage.
LAS VEGAS SHOOTING : HOW IT HAPPENED "Then two rows in front of me a woman goes down and a man yells that she’s bleeding and people duck down," Compton said. "And I’m just standing there." Compton 's friend yelled at her: Get down! But she didn’t immediately understand what was happening. "Even three or four minutes into it, I was still thinking, ‘This can’t be happening.
Kirstyn Schechter Explanatory Essay Grit Wouldn’t you want to be very determined and follow your dream? If so, you need to have grit. In the TEDTalk, "The key to success? Grit”, by Angela Lee Duckworth she states “Grit is passion and perseverance for very long-term goals. Grit is having stamina.
3. Hematoma is when a blood vessel breaks due an injury and it causes blood to collect outside of the vessels. 4. Cyanosis causes the skin to turn bluish because the blood doesn’t get enough oxygen. 5.
Because there is no legal or official definition for the term, what constitutes a mass shooting in this country often varies (Also, mass shootings can only be defined by statistics provided in recent modern history, because incidences like these may have been recorded in the past, but it is often hard to recover that kind of data, whereas now information from incidents that occur now is easily accessible. (CNN)). According to the FBI, a mass shooting is an incident in which “four or more shot and/or killed in a single event [incident], at the same general time and location, not including the shooter” (Mass Shooting Tracker). However, a more widely recognized definition, is “a shooting with at least three victims, excluding the perpetrator” (CNN). The bar for an event like this occurring is set so low, that many people don’t even realize that these incidents occur on almost a daily basis—they occur so frequently that the mainstream media often only reports mass shootings where dozens of people have been injured or killed.
Haemostasis is a physiological process of blood clotting and dissolution of the clot, followed by the repair of injured tissue. It results from interplay of vascular endothelium, platelets, coagulation factors, anti-coagulation mechanisms and fibrinolytic system. The fluidity of blood in the absence of injury is maintained by the balance between pro-coagulant pathway, and the mechanisms that inhibit the pro-coagulant pathway. Imbalance between the two mechanisms, for example during clinical illnesses or preoperative period, predisposes a patient to either bleeding or thrombosis. To stop bleeding after injury, a complex process is initiated within seconds.
