Ballistics Essays Ballistics Essay Ballistics Essay Paper Ballistics Bullets traveling over two thousand feet per second and having more energy than one normal person can perceive. Can you imagine tracking where, how, when, and what from angle this bullet was shot. Ballistic scientists can. Ballistics is the study of any projectile used as a weapon. This can certainly make or break a case Involving a guru Great ballistic scientists can even provide how far the bullet was shot from before It makes contact with the target. To me this is one of the most Important tools in a case where a firearm is used. The definition of ballistics is very simple, the study of projectiles from a weapon, mainly referring to bullets out of a gun. That Is a dulled down definition. My definition is a little lengthier in depth. Forensic ballistics includes the examination of bullets and firearms in an attempt to identify particular weapons used at any particular time. Guns and bullets leave small signs behind when fired, which professional ballistic scientists can pick apart and define what gun, bullet, energy, and even charge of the casing. This makes ballistic scientist one of the most important keys on a law enforcement agency. Pistols and rifles are categorized by what the inside diameter of the barrel measures. This is called caliber. An example would be, a 22 caliber rifle has a much smaller diameter barrel than a . 370 caliber rifle does. In turn, the bullet of a . 22 caliber is going to be considerably smaller than that off . 370 caliber, Pistols are categorized the same way. A . 40 caliber is much smaller than a . 460 caliber. Shotguns, however, are not categorized Like this. Shotguns are categorized by gauge. Unlike the rifle, the smaller the gauge of a rifle the bigger the inside diameter is. Such as, a twelve gauge has a much larger barrel than a twenty-eight gauge. Now that I have explained sizes and categorization to the guns, next Is the operation of the guns. When a gun is fired it takes many parts to make the gun fire and also for the bullet to hit Its target. When you pull the trigger on a gun, the firing pin strikes the bullet to set tot the gunpowder. That leaves a mark on the casing as unique as a fingerprintno two guns strike the bullet in exactly the same way. Furthermore, the barrels of every gun are rifled, which means they contain grooves, wanly Nell ten Dulled spun Ana make It more accurate. In turn, ten Dulled NAS ten marks from the rifling in the barrel, which can be matched up to the weapon that fired it. There is one exception to the rifling in the barrel. That exception is smooth bore shot guns. They are smooth, Just like the name implies. Now to talk about the term most people deem as ballistics, the speed, drop, and energy off bullet. Charge, weight, and muzzle length are three things that affect the speed and drop off bullet. Something most people don?wet know is that a bullet does not shoot straight horizontally. When I bullet is shot it is shot at a raising angle. Which means the bullet breaks the plane of the muzzle once before hitting the target. A . 22 caliber rifle breaks the plane of the muzzle at twenty-five yards, if the rifle is zeroed at 100 yards. Not all rifles cartridges cross at these measurements. That all depends on the weight, charge, and velocity of the bullet. Weight can also be described as knock-down power. A high caliber rifle will shoot heavier bullets and have more knock-down power. The more weight means that there is more kinetic energy. For example, a . 357 caliber rifle shoots a lighter, much faster bullet than that off . 5 caliber. Although the . 57 is faster and more flat shooting, the . 45 caliber has more knock-down power because of the weight of the bullet and the kinetic energy. Although this information is more helpful too hunter, it is useful to any shooter. Charge is described as the amount of black-powder used to fire the bullet. The more the charge, the bigger the bang. Every gun uses black-powder to be fir ed. Black-powder was the first explosive, and used in every gun in the history of fire- arms. From the oldest muskmelons to the most high tech sniper rifles used today. Now that the velocity of the gun is covered, next will be to explain what happens o the bullet once it hits the target. There are many different types of bullets. Such as soft tip, hollow point, and wad cutters. There are also a few types of hollow points. Hollow points are bullets that expand, (or mushroom) once they have impacted the target. These are most common and also the most harmful. Not only do you have a bullet traveling at over 1 500 feet per second, but they also expand and leave gaping entry and exit wounds, and can also leave trace amounts of the bullet inside the target. One type of hollow point is a slow expanding bullet. It works exactly like it is babbled, it is a harder bullet that still expands, but may not fully expand until it is very far into the target. These do a lot of damage, but not as bad as a fast expanding bullet. Fast expanding bullets expand as soon as contact is made with the target and is the most lethal type of bullet. Because they open so quickly you get the mushroom effect completely through the target. Wad cutters are nothing more than a solid piece of lead. They are mainly used for target practice because they are very cheap and do not have the charge nor the velocity of a hunting load. Although they arena t as powerful they are Just as harmful. Since they do not expand they stay a solid completely through the target and also after if there is an exit wound. These are Just as deadly because they can ricochet inside off target such as a human. Wad cutters are used in a lot of gang fights because they will not kill someone, but they will penetrate the skin and once inside the person they will ricochet off of the ribs and sternum, doing much internal damage. On each and every gun manufactured, there is a serial number stamped into it. It Is made Day pressing ten metal so even Day Telling Tontine serial under Trot ten inside, the scientist can still use ultra-sound to find out the serial number. Filing off serial number is a crime in itself and is very common in gangs, drugs, and acts of violence. By acquiring this serial number ballistic scientists can find out the caliber, make, model, store it was sold from, and even the owner. This is a huge factor in ballistic science. If you can place a gun with an owner/operator, as a ballistic scientist you have won half the battle of solving the crime. Ballistic scientists not only work with the operation of the gun, but also the distance and angle the bullet was shot from. For instance, the entry hole on a target well be much smaller than the exit hole because of the expansion of the bullet and the velocity that it exited at. In this case if you can determine and entry and exit wound you can tell what angle the bullet was shot from and determine the vicinity that the shooter was when the bullet was fired from the firearm. Distance is a huge key to figuring out what happened at a crime scene. A bullet fired from point-blank range out to a very close range will leave a black-powder burn on the target. A shot a point-blank range will have a tighter more distinct burn than en of a shot from a further distance. Another determining key to distance is penetration. If a bullet has not completely passed through a victim it could have been fired from a farther distance than what the proprieties of the scene allow. Some of the tests and examinations of ballistics include a few different types of test shooting. The ballistic scientist will test shoot the gun to find out its markings and striations on certain types of bullets to try and match a bullet with a gun and even a gun with an owner. That type of test can obviously only be done if either remains of the bullet or the gun is found. If neither the gun nor bullet is found at the scene the scientist can shoot different types of guns into what is called ballistic gel. This gel is comparable to the skin, muscle, and fat off human. It is a clear gel so you can compare the wound channel of the victim to that of the gel. This is also helpful with studying expansion of a bullet considering the gel is clear. Collecting evidence from a crime scene is very important. You do not want to hurt any evidence that could hinder the case. When collecting evidence such as a gun, never place a pencil inside of the barrel or trigger guard. Not only is that not proper rearm safety it is also harmful to any evidence that is located there. The firearms can be picked up by the textured part of the grip, while of course wearing rubber gloves to leave no extra fingerprints behind. Before picking up the firearm, make sure it is pointing in a safe direction. Most criminals do not unload the firearm before they drop it at a crime scene. Keep notes on the condition of the gun, the location, and time it was found. These call all be key factors in telling when, where, why, and how the victim was shot. If the barrel is damaged in any way, it will affect the outcome of test shooting. The same goes for the firing mechanism. The firearm should be contained in either a large envelope or a paper bag. It should be kept separate from the bullets, casing, or magazine. Putting all of these pieces of evidence in one container can lead to scratching and damaging any piece of evidence. As for collecting the bullet or casing from a scene, you must be very careful and collect it right or it will be no good as evidence. Since casings and bullets are metal, IT tenure Is any metal on metal contact ten specimen can De rule Ana scratches. This is why you would want to collect the evidence by hand with gloves on. Also one thing that most criminals don?wet think about is when you are loading your weapon you are leaving your fingerprints on the casings as you load them into the magazine. This is why casing are very important to any case. You would not want to use metal tweezers. If the bullet is scratched it could lead to false reading in test shooting or examination. Bullets and casings should be placed in a separate small cardboard box or a small envelope at the least. When collecting a magazine you should take the same precautions as you do with the gun, bullets, and casings. The magazine can be a very important part of the rime scene. Let?was possible that the magazine that was left behind could still have cartridges in them that have not been fired. If so that could narrow down the search for the caliber of gun and also the type of ammunition that was shot. Also with finding the magazine you can examine it for fingerprints from when the magazine was loaded and unloaded. With finding such things as the magazine, bullets, and casing you can determine many things such as, position, distance, caliber, gun, and even an escape route if the magazine was dropped. When I had first chosen the topic ballistics I thought I would be more focused on he science part of ballistics. But once I researched and put some of my own knowledge to work I realized that I was more interested in the way guns work and the way bullets travel. Although I don?wet see myself as the laboratory type, if I could only work on firearms cases it would not be that bad of a Job. I know as a student I learned very much in my research of bullets, guns, and ballistics. ?catheter are hundreds of millions of gun owners in this country, and not one of them will have an accident today. The only misuse of guns comes in environments where there are drugs, alcohol, bad parents, and undisciplined children.

Financial Analysis - Essay Example For this purpose, the performance of the company for the last few years has been taken into consideration. The results are compared with that of its competitors to determine the relative position of the company within the industry. Comparison will also be made with the industry standards to determine the effectiveness with which it manages its performance. Marks & Spencer (M&K) is a UK based retail company that offer products known for their high quality. The product portfolio of Marks & Spencer is highly diversified, comprising of food products, household related goods, apparel and many more. The company started as a single retail store in early 1884 and became an international retail chain in a matter of few years. Within a time span of 125 years, the company had diversified itself and entered more than 41 overseas territories. It boasts of 21 million footfalls per shop per week (M&S-a, 2010). To determine the short term performance of the company, its financial statements for the last three years will be taken into consideration. This time period will be stretched to 5 years to understand its long term trend. To determine the current position of the company, its present performance in 2009-2010 is compared with that of 2007-2008. Such comparison is initiated to understand the effect that economic recession had on the company. This will also help to analyse how the company managed to overcome the recessionary phase. Reports have revealed that recession had no major impact on the total revenue of the company. Only, a fall of 0.44 percent was registered in the total revenue. However, the operating profitability did suffer a fall of 28 percent. In the same way, the net profit (profit after tax) also reduced by 38 percent. As the operational cost increased, the management reduced its net debt by 19 percent. From the above fact and figures, it can be concluded that the revenue of M&S was affected marginally

Analysis summary based on common ground paper - Essay Example Today, people would like to know the factors why Saginaw was totally left behind, neglected in terms of socio-economic-political growth as compared with its other neighboring cities. This paper attempts to present some valuable insights that may contribute later to a deeper situational analysis of Saginaw as well as cite and emphasize the missing elements that must be provided with full support and attention. Saginaw is supposed to take the road towards change for a Better Saginaw. This means that all existing resources, strengths, opportunities as well as its exigent problems must be contained in a holistic plan that will address the needs of the city and its people and bring about changes that will chart its development. Moving towards this route, Paoli and Sarah Pedini have already pointed out that Saginaw has the most important resource of all, its People, who they claim are inherently artistic and creative. Should these traits be properly harnessed, utilized, supported and linked with local and international based commercial businesses, these can bring significant revenues to Saginaw. They also mentioned that Saginaw takes pride in promoting its existing old ancestral structures like museums, natural wildlife habitats, spaces for productive cultural activities, parks, etc. that could be developed to attract and develop its tourism industry. In addition, Dr. Chris Schilling, a resear ch Engineer (SVSU) and also a resource person, expounded on the different potential resources of Saginaw which can be tapped and developed as new Saginaw showcase industries (e.g. combined wind- solar industry, energy farming and recycling industry) that will attract external investors who will bring more jobs and income to the city of Saginaw. Like any other city, Saginaw faces deterrent factors to its development as well as new challenges. Greg

Moliere’s Portrayal of Religion and Religiosity Essay Example for Free

Moliere’s Portrayal of Religion and Religiosity Essay Moliere’s Tartuffe is about a man named Tartuffe who is a beggar and holy man that was recently taken in by a Christian man named, Orgon. Tartuffe has Orgon fooled, but the entire rest of Orgon’s family sees Tartuffe as a hypocritical, self-righteous con artist. Orgon becomes obsessed with Tartuffe and would rather talk and hear about him than his own sick wife. Even though Moliere rewrote this play twice, there are many reasons that the church might still be concerned about the hypocrisy that he used toward Christianity in this play. In 1666 Tartuffe was banned, a play many found offensive because of its assault on church hypocrisy. Many people of the church could still be concerned, due to Moliere’s portrayal of Christianity and how it is almost mocked in this play. Allot of the comedy Moliere portrays is intense focus on Orgon as example of a certain kind of traditional Christian. He isn’t the ‘only’ type of Christian in this play, but the way he is portrayed is almost in a hypocritical manner. Orgon is so eager to believe Tartuffe, mainly due to the fact that Tartuffe is professing to be another type of Christian. Moliere regards the type of Christian that Tartuffe is as insane. The way mankind is portrayed on behalf of Orgon is almost as depraved as a result of Original Sin, so therefore Orgon has to be subjected, for his own good, to somewhat of a dictatorial control by divinely appointed authorities, or the King. Moliere portrays Orgon as a good Christian man, who is taken advantage of and ultimately almost loses everything because he is willing to take Tartuffe in and treat him as if he were family. The reason the church should be concerned here is the fact that Moliere portrays the way Tartuffe is insane and manipulates the good Christian man. He shows Orgon, the good Christian man as blind to all the wrong, and coming out as essentially the â€Å"loser† and the insane Christian and manipulator, Tartuffe, comes out with all of Orgon’s belongings. After reading Moliere’s Tartuffe I now can see how the church would be heavily concerned with how Moliere portrays Christianity as ‘the nice guy finishes last’ with relation to Orgon and Christianity. The church could also see the hypocrisy by the portrayal of Tartuffe as a â€Å"religious con man† or â€Å"religious fraud. †

How Frederick Douglass Changed History Essay -- slavery,emancipation pr

There are numerous individuals throughout the past that had the chance to leave a stain in the fabric of history. But, small amounts that stood up and represented slavery in the United States. The immoral selling of beings to becoming a slave is recognized as slavery. Slavery had a huge role in the United States history, getting down in the 1600’s and was abolished in the 1800’s. African-American slaves were maliciously being walked on, as if they were carcasses, for a hundreds of years. Although, slaves were prevented from being educated, one particular astonishing African-American fellow was able to change overpass this situation. Frederick Douglass changed the United States for the better. Douglass was born on the seventh of February 1817, in Tuckahoe, Maryland. He was the son of an African- American slave named Harriet Bailey. Though slaves were unable to be educated, Douglass had a huge thirst for learning. He became a self-taught slave child, with a little assistance from his owner. Douglass had gained important knowledge (was now literate), which made him realize that there were many other opportunities to increase his education. After several abortive attempts to run-away in 1836, he then succeeded to escape. Once reaching New Bedford, Massachusetts he assumed the name Douglass (his birth name was Frederick Augustus Washington Bailey). After many years of his educations in England, he was able to buy his freedom before returning to the United States. Douglass later rose through determination, wisdom, and eloquence to shape the American nation. He became an abolitionist, human rights and women's rights activist, public speaker, writer, journalist, publisher, and s ocial reformer. One way Douglass was able to change Amer... ...ower (whites) to take action against slavery. Douglass did not only stand up for slaves but also for women’s rights, helped lay the groundwork of women’s suffrage. If Douglass was unable to escape slaver, many civil rights could have been delayed. Works Cited Clark, Charles S. "Feminism's Future." CQ Researcher 28 Feb. 1997: 169-92. Web. 27 Mar. 2014.

Day Care Center vs Nanny

There are many parents who are looking for someone who takes care of their children while they are away. Their option will be a day care center or nanny. If you are one of those parents, I want to persuade you not to choose quickly because they are not the same. They provide your child with different environment, you should select after understanding their similarities and differences. The first similarity between a day care center and nanny is that they take care of your child for specific period. Some parents can’t have jobs or study and pursue careers. It is because they have to take most of their time off for taking care of their children and don’t have time to do it. The job of day care provider and nanny is to help those parents by taking care of their children. The second similarity is that a staff in day care center and nanny are trained people. They are educated in early child development or a related field. It means that they can assist your child in developing his academic skills. They can help children with preparation for kindergarten and children who are in school with homework. Also, because they studied early child development or related field, they know children’s emotional needs and how to discipline properly. The third similarity is that they have issues with illness. Day care center can’t let you leave your child with them when he is sick. It is because, in the day care center, children are in close contact with other children ant it will let germs spread easily. On the other hand, it is needless to say, but a nanny can’t take care of your child when she is sick either. The first difference is the number of children they take care of. Day care provider can’t take care of multiple children because there are many children in day care center. It means that they will not give one-on-one attention to your child. However, your child’s being among many children will good to your child. Your child will learn how to socialize because he will interact with other children. On the other hand, nanny is responsible for only your child, so your child will be able to open his heart to her quickly. The second difference is the location where they look after your children. Needless to say, if you choose day care center, your child will be taken care of in the day care center. Your child may feel uncomfortable because he can’t move freely in the day care center like he does in his house. On the other hand, nanny comes to your home to take care of your child. Your child may feel comfortable to be in his house, but he will not be able to make friends like he can in a day care center. The third difference is the cost. You will have to pay for day care center between 62 dollars to 320 dollars a week. On the other hand, the cost of nanny is from 350 dollars to 700 dollars a week. The cost of day care center is much cheaper than the cost of nanny, so to put your child into a day care center will help you a lot with money. However, a nanny does things worth the cost. For example, if your child is allergic to a certain food, she will not cook meal that contains that food if you ask her. This will not be done in day care center. As you know now, a day care center and nanny are similar, but not the same. They provide different environment for your child and affect you differently. Because of it, you have to consider carefully with whom you should leave your child while you are away.

Narcoterrorism Definition and Examples

The term â€Å"narcoterrorism† is often attributed to Peru’s president Belaunde Terry in 1983, to describe attacks by cocaine traffickers against the police, who suspected that the Maoist rebel group, Sendero Luminoso (Shining Path), had found common ground with cocaine traffickers. It has been used to mean violence waged by drug producers to extract political concessions from the government. The most famous example of this was the battle waged in the 1980s by Pablo Escobar, head of the Medellin drug cartel, against the Colombian government by way of assassinations, hijackings, and bombings. Escobar wanted Colombia to revise its extradition treaty, which it eventually did. Narcoterrorism has also been used to refer to groups understood to have political intentions that engage in or support drug trafficking to fund their activities. Groups such as the Colombian FARC and the Taliban in Afghanistan, among others, fall into this category. On paper, references to narcoterrorism of this sort suggest that trafficking merely funds a distinct political agenda. In fact, the drug trafficking and armed violence by group members can become an autonomous activity to which politics is secondary. In this case, the only distinction between narcoterrorists and criminal gangs is the label.
