Surgical Techs were originally performed by nurses. The succession of World War I and II‚ Korean War‚ and the Vietnam War made a huge need for health care and physicians. Medical technicians started serving the role of a “scrub tech” in the operating room. During the time of the Korean War‚ physicians started using medical technicians as assistant instead of nurses over the years http://www.alliedhealthworld.com/surgical-technologist.html Hospital- based programs were developed for surgical techs in the

the four different pigments types of a leaf. As the filter paper with the solvent will separate the pigments in terms of solubility‚ a clear segmentation of each is expected to show off. As various chemicals were used in the whole process of this lab‚ certain variables might have influenced the results in terms of the purity of each chemical or purity of the used filtrate. Background The chloroplast‚ basically‚ is the organelle responsible for photosynthesis. Structurally it is very similar to

zmosis The IB Lab Report Measuring osmosis 1. Introduction My experiment is about osmosis on a potato and if or the quantity of salt affects osmosis. I would do the experiment with 5 potatoes cut into squares all the potatoes weight the same so the weight can`t be a variable the I put the potatoes on 5 different plastic cups with different amounts of salt and then I weight them again to see if the quantity of salt affected the osmosis of potatoes 1a. Research question ¿Does the quantity

Chemistry 207 (Lab # 1) 9/11/12 Experiment #1: Cooperative Identification of an Organic Solid A. What needs to be done: In this lab‚ one will identify the identity of a colorless organic solid by experimentally finding the physical properties of the solid. Such properties include melting point‚ mixed melting point‚ and IR spectrum. With these properties‚ one will be able to compare their results of the organic solid to see if any other classmates have the same unknown sample. B. Timeline:

Abstract: When ionic compounds are dissolved in water‚ they break apart into ions. In this lab the opportunity to mix two ionic solutions and observe the results was given. Some ions will remain dissolved and uncombined in the solution even when they are mixed with other ions. When other ions are mixed‚ they form compounds that appear as cloudy or grainy precipitates. The objective of this lab was to observe the formation of compounds and to write the names and formulas of ionic compounds. It is also to

were placed inside Peeps. After the five Peeps were placed in each microhabitat our predictions were that as the ectothermal organism increased in elevation‚ the temperature of the organism would decrease do to access to the wind and convection (Biology 301 Handout 2013 Thermal Enviroments). After gathering the temperatures from the I-buttons‚ over a twenty minute reading in each microhabitat the data was organized in Excel to be placed into an ANOVA calculation to calculate the null hypothesis

Adol Condensation Introduction: This reaction is carried out by adding benzaldehyde and acetone into a flask. The product created is a 1‚5-diphenyl-1‚4-pentdiene-3-one‚ which includes two double bonds‚ and two benzyl ring functional groups. This is a dehydration reaction that occurs twice in order to form the diene. After obtaining the product‚ via vacuum filtration‚ it will be recrystallized and then analyzed for purity by determining both products’ melting point. The two products will be

The Effects of Individuals’ Detection of Changes in Images on Reaction Time Abstract The purpose of this current study was to examine how individuals detected or noticed change when viewing images on their level of attentiveness. The experiment consisted of 22 participants who had to detect change across conditions for 20 minutes. These conditions were importance of change (marginal and central) and change type (color‚ location and disappearance and reappearance of images). These
