Nanotechnology : The World Of Nanotechnology

The author of this article is Carolyn Medrano. She wrote this article to inform the reader why technology in the classroom is beneficial. This helps me because I am arguing that technology is beneficial in the classroom. There are many reasons listed in this article about how it is useful in the classroom. It also kind of talks about the viewpoint of the students and how there are many ways that they use them in the classroom. It explains how some websites are effective in learning. It tells that teachers think that the use of technology has helped them in their ways of teaching.

These types of problems are problems that I want to fix, and being that these problems have apparently not been solved yet, I am going to try my best to solve by researching different types of body armor throughout the world and look for which type would better suit these problems such as “liquid body armor” which works better than standard body

World War Two's most famous contributions to the history of body armor is the flak jacket. Made from ballistic nylon, the flak jacket was "cumbersome and bulky" and "was ineffective against most pistol and rifle threats," (Bellis, n.d.). However, flak jackets were very effective in preventing casualties related to shrapnel. Shrapnel did account for as much as 70% of all Second World War casualties (Pike, 2011). No significant advancements in body armor were made between the end of World War Two and the 1970s. Even during the Vietnam War, flak jackets were still being used. In the 1970s, though, Kevlar was invented. Kevlar and other lighter weight materials allowed for constant protection that was relatively comfortable to wear. Moreover, the improved materials could protect greater surface area on the body. As Pike (2011) points out, "Most fatal penetrating injuries were caused by missiles entering through areas not protected by body armor, such as the face, neck, pelvis, and groin." Unlike earlier materials, Kevlar also

The energy absorbed by the fabric in the armor is equal to the loss of kinetic energy carried by the bullet during impact.

Common sense would tell us that a bigger bullet is a better bullet. But, bigger bullets have greater felt recoil and since most

People have a lot of questions about the bulletproof vest and I have written this story to answer all of these questions and even given you some facts. Like this one of them is what are they made of and other stuff like that. This story should answer all your questions.

If you watch an action film, you see people get shot all the time. Sometimes it's stupid, most times it's stupid, but in war movies, it's pretty tragic. If you've ever seen someone shot in real-life, it's even worse. There is no classic lines, there's shock, fear, panic, crying, and the horrible unknowing of what happens next. One of the biggest things about a gun shot is that it's hard to seal. Most just know to put pressure on the wound and to get that person to the hospital as quickly as possible. But what if you could seal the wound in 20 seconds to give the victim a better chance at surviving the wound? Good news!

Mcleish’s Armor and Anesthesia: Exposure, Feeling and the Soldier’s body is about how the soldiers’ training, weapons and environment itself is a threat to them. Mcleish volunteered at at U.S. army’s Fort Hood in Texas where he had the opportunity to conduct research on them and he came up with that. He then talks about Frank a truck drive and Petey an infantryman and how they suffered from strain injuries. They talked about IBA a body armor and how it can protect you from 7.62 mm AK-47 rounds at range but not a 9 millimeter up close because that there are parts of the body that are not fully covered. His argument is convincing because he states how the amors does work because that the ballistic glasses protects your eyes and vests stops bullets

In a Army Research Lab in North of Baltimore scientist are try to make the next evolution of warfare innovation. They are probably going to use liquids to make there be less injuries and it will soften the empact. They also want to prevent the whiping of their heads when it hits surface. They think that the equipment will do the same jobs as they

Today, vaccination is regarded to as one of the greatest medical achievements. A lot of diseases such as smallpox, that were killers thousands of years ago are have become almost nonexistent all thanks to vaccines. Over the last a few years, there has been arguments and debates about how effective vaccines are. Vaccines contain weak viruses and when entering the body, the immune system identifies the foreign substances (antigens). Once the antigens are identified the immune system develops proteins called antibodies which are made of lymphocytes of B-cells; the antibodies circle in the body and kill antigens. Memory cells then remember the antigens so that when exposed to the same antigens again, they'll kill them. Still, 160 years after the invention of the needle and syringe, they are still being used to deliver vaccines. On the podcast "A needle-free vaccine patch that's safer and way cheaper", Mark Kendall argues that it's time to advance. He states that even though vaccines are successful technology and have increased our life span, the needle and syringe have some shortcomings. These shortcoming are cross-contaminations with needle, it could hold back next generation's vaccines in terms of immune response, and it could be responsible for the problem of cold chain.

Due to the extent of combat warfare that soldiers endure, “military personnel are sustaining TBIs at unprecedented rates due to the style of warfare” such as explosives, which is only the beginning of the problem (Wolf et al., 2012). The main concern related to the soldiers who sustain TBIs is the extent of their physical and

Humans throughout recorded history have used various types of materials as a body armor to protect themselves from injury in combat and other dangerous situations. The first protective clothing and shields were made from animal skins. Eventually, metal was also used as body armor, what we now refer to as the suit of armor associated with the knights of Middle Ages. (“Bellis,Marry”). During the middle ages, an Italian named Filippo Negroli was known to be knowledgable in fashioning steel. His skills were commissioned by the Duke of Ubino. Together, they have marked the production of the very first kinds of bulletproof clothing. However, the vest’s, heaviness and restriction to movements made their especially designed body armor became a problem rather than an advantage during the war. Together with the minds of other people who

Wounds containing embedded metal fragments are not a recent phenomenon. However, the introduction of unique metal mixtures to the modern battlefield, as well as the insurgents use of improvised explosive devices, have resulted in the potential of embedded fragment wounds with materials whose toxicological properties are not well understood. The Armed Forces Radiobiology Research Institute was one of the first laboratories to study the long-term health effects of embedded fragments of military-relevant metals. Responding to concerns over the effects of wounds containing depleted uranium, the Institute developed a rodent model system to investigate this issue. As additional unique metal mixtures were incorporated into weapons systems, the

First of all is what it’s made out of. Bulletproof clothing is made out of woven. Which is strong material. That way they use woven so it can stop a bullet hitting you. The bulletproof vest is the main thing of this bulletproof clothing. There are dozens of layers of woven smashed together so it can stop a bullet. If there were not that many layers of woven together than a bullet could probably hit you bad.

For instance, NASA’s research in the use of lightweight, ultra-strength alloys known as ‘metallic glass’ greatly affected the way sports equipment is manufactured. Being the first of its kind, it was “more than twice the strength of titanium, one of these new alloys is without weak spots and highly resistant to deforming, which allows for near-total energy transfer, lower vibration, greater comfort, and increased performance” (NASA Technologies Benefit Our Lives). Developed by NASA to prevent g-forces from harming astronauts, shock-absorbent foams are able to take the form of preset objects and retract to their original shapes. Current athletic helmets and protective padding would not be as effective without this shock reduction technology. The same material is found in medical beds, footwear, fighter jet, and furniture (NASA Technologies Benefit Our
