For my Field Study Day I had a confusing turn of events that caused me to go and a research paper on the movie Everest. My original plan was to volunteer at the Elks Lodge but when we arrived there we couldn’t find anyone and waited an hour and a half before leaving. We tried going to a few places nearby, like a church and a retirement home to ask if there were any volunteer opportunites to no avail. So as a last ditch effort we went to the movies and saw Everest. This movie is based on an…

In early May 1996, two teams of commercial expeditions led by highly experiences climbers attempted to reach the summit of Mount Everest. Out of the 23 mountaineers that attempted the summit, only 18 survived. Of the five that perished, two men, Rob Hall and Scott Fischer, extremely skilled climbing leaders with previous experience reaching the summit, did not make the decent. Since that deadly expedition in 1996, many, including the survivors of that climb, have attempted to explain why the…

“With enough determination, any bloody idiot can get up this hill, the trick is to get back down alive.” This quote from Jon Krakauer captures the gripping story of Into Thin Air which summarizes Jon’s emotional and physical journey while climbing the tallest mountain in the world. Through extensive climbing and note-taking Jon is able to share his experiences and tell a riveting story about his life or death experience from the perspective of a reporter which provides an amazing point of view…

We started preparing to leave for Everest on June, 2015, even though we were delayed for preparing and for the season. After several checks, however, we found a perfect weather window for summer, with few monsoons from India. So we scheduled the real ascent the first week of July, and two weeks after we sold most of what we had, and put in boxes all the gear we already had. Summiting Everest depends on a number of factors, and any experienced climber knows this. Because Everest is the tallest…

In the letter, Anatoli Boukreev (Responds to Krakauer), Anatoli Boukreev comments on the topic of his decisions and actions regarding the Mount Everest expedition on May 10, 1996. He argues that he has had more than twenty years of experience in climbing high-altitude mountains, and he is able to make rational decisions without the aid of supplementary oxygen. The first issue that Boukreev addresses, is his decision to retrieve supplies from camp for others. When Boukreev encountered Scott…

Methods Column chromatography was set up using a 60 ml syringe clamped to a ring stand. The syringe was plugged using a small amount of cotton. An Erlenmeyer flask was placed underneath the column to collect any excess material. Eleven 20 ml vials were labeled numbers 1 through 11. Silica gel was measured to 42 ml using a graduated cylinder and then moved into a 150 ml beaker. A slurry was created by adding 50 ml of hexane to the beaker containing the silica gel. The slurry was stirred for…

2.4 Optical density Yang, Gao & Jiang (2012) investigated Study on the Relationships between the Optical Density and Ink Film Thickness Based on the Offset Overprint Trapping. D=D∞ (1-e-ml) formula represents the relationship between ink thickness and ink density. By using the formal of one-color ink thickness and ink density, the second density that corresponds the first major density is transferred to the equal thickness. Then they are added together. The experiment was carried out using 128…

Introduction Thin-layer chromatography, otherwise referred to as TLC, is a fast and inexpensive way to determine the amount of components in a solution or to identify an unknown compound. The principal behind TLC is when different compounds are placed on silica gel or alumina, (stationary phases) they will travel different distances when eluted with the proper solvent. According to ChemistryGuide, this is because the more polar compound has a stronger interaction with the silica gel due to its…

paper, column and so on. 1 Chromatography differentiates by allowing the differences in polarity, vapor pressure, solubility and so on of different substances to be observed. 1 In our endeavor, we will be using specific types of chromatography, termed Thin-Layer Chromatography (TLC) and column chromatography. Essentially, TLC is an adsorption aspect of chromatography that uses a polar stationary phase and a non-polar mobile phase, and utilizes capillary…
