Separation of plasma proteins by molecular exclusion chromatography Sebastian Prisacariu 140013826 Introduction The components of blood is broken down into 3 parts. This breakdown is consisted of: Plasma which is a yellowish fluid that helps transport blood cells around the body and contains a small supply off proteins, platelets which are blood clotting agent, red blood cells which is a carry for oxygen and remover off carbon dioxide and white cells which is the bodies defence from infection…

The aim of this experiment is to determine through calculations the concentration of acetic acid content within a common white vinegar. Apparatus / Materials Plastic Tray Electronic scales Sodium hydroxide Volumetric flask and lid Glass funnel Distilled water Pipette Volumetric pipette/s (5mL, 20mL) Bulb Conical flask Retort Stand Burette Burette clamp White Tile Method Place the plastic tray on the electronic scales and press tare to set the wither to zero; Weigh out 0.7993g of Sodium…

The main issue with FOS was coming up with an algorithm that determines the important deliverables of thermocouple systems by using time history data generated from a first-order system. Deliverables include: our MATLAB coded algorithm -which outputs the parameters yL, yH, ts, and � - an executive MATLAB file -which outputs SEE and standard deviation values- and a regression plot which compares the prices of FOS models to �. Determining these four parameters within 20.0% of the calibrated data…

There are several measurements used today that measure situational awareness, each with its own uniqueness, pros, and cons. The first is the Situational Awareness Rating Technique (SART) which is a subjective measurement for SA developed by Taylor (1989). In SART, participants are asked to rate their own SA levels throughout the scenario, which allows to see how participants think they preform and to measure their perceived SA. However, when using subjective measurements, it is possible that the…

Science coming from the Latin word Scientia, meaning “knowledge,” is a systematic structure that builds and organizes knowledge from testable explanations and predictions about the universe. The nature of scientific progress and the rationality of scientific change lies between Karl Popper and Thomas Kuhn. The two prominent philosophers of the 20th century had very distinct viewpoints of science which led to countless debates. One of them, which I believe to be the most intriguing, was the…

1. The Tag Out Instruction ref (a) is consistently being violated in the field. The Tag Out Instruction is too burdensome in its present form. This makes it difficult and very time consuming to properly tag out a piece of equipment. This instruction is not being followed due to convenience and/or time. This creates a dangerous work environment. Not following proper procedures set forth in ref (a) can also lead to the catastrophic failure of Coast Guard equipment, costing hundreds of thousands of…

The landscape of clinical research is rapidly changing, due in large part to technological advances. Differentiate between what you do as a CRA now, in 2017, and what the role of a CRA will look like 10 years from now. (Response below is 488 words) The role of CRA will be more office/homebased due to the following reasons. Onsite visits will be performed to confirm that the PI is present, IP and study supplies are maintained and a limited investigator site file is present: 1. SDV: Now, SDV is…

possibility that the machine will not work properly due to a glitch or failure of some kind. Machines need to be frequently calibrated before, during and after use to ensure accurate readings. If this is not done or too much time passes between calibrations the readings obtained will be incorrect and the results will not be useful. Furthermore, if the equipment is placed on the client incorrectly or the client moves around and jostles the equipment resulting in an altered placement it…

Gas chromatography (like any other chromatography) is a separation technique in which the mobile phase is a gas. This technique is applied for the separation of volatile substances. This method separates a mixture into its components and is used to measure the concentration as well as it identifies the components. GC creates a time separation rather than physical separation which means that the components are separated in time. After they are detected, a chromatogram is generated. Each peak in…
