CORONARY STENTS Before stents were used, balloon angioplasty was used to treat narrowed coronary arteries. This involved inserting a very thin, long, balloon-tipped tube into an artery where there was a blockage. The balloon at the tip of the catheter was inflated to compress the blockage and restore blood flow. It was then deflated to remove the catheter and balloon but because no support was left at the site of the blockage, in some cases, the artery collapsed. This is why small stents were…

As a person, I am unique. I am girly, and fun, geeky, quiet, obnoxious, sarcastic, caring, musical, and most importantly; myself. Carly Jones. I am always true to myself, no matter the situation. First of all, my music is the most important thing to me. I used the opening of Gabriel Faure’s Fantasie, as the backdrop to my poster because that song is always playing in my head.

trip. The wet plate camera, also known as the wet collodion process, was an early photographic technique invented by Englishman Frederick Scott Archer in 1851. The process involved adding a soluble iodide to collodion- or cellulose nitrate- and coating a glass plate with the mixture. After being submerged in a silver iodine solution in a dark room it was then exposed in the camera and developed by pouring pyrogallic acid over it and fixed using a strong solution of sodium thiosulfate. The…

Living things are highly organized, and have may other characteristics that accompany it. The general agreement among scientists is that there are seven main characteristics of life; cellular organization, metabolism and energy use, response to stimuli, regulation and homeostasis, growth and development, evolution, and…

stay at home during the storm, unable to leave at the risk of being on the unsalted roads and swerving off into a ditch. Millions of trees had fallen over, due to the heaviness from the ice. Some of the trees had benefited from glaze ice, a smooth coating of ice forming around the trees and plants from the freezing rain. This helps to relieve the unhealthy parts of a tree, like dead branches to fall down quicker. The damage cost of the disaster had been a whopping $106 million. The storm…

There are two main categories…

rainforests receive more than 100 inches of rainfall a year, so the plantlife had to adapt to receiving a lot of water. Some of the plants learned to shed off water from their leaves so they would not break. Other plants that are growing there have oily coatings, or a drip tip to help them shed off water. Over 2,500 vines grow in the rainforest, the vines grow from one tree to another and make up 40 percent of the canopy leaves. Some vines have spikes that help them latch onto other trees so…
