Comparison of Extended Column Test (ECT) and Propagation Saw Test (PST) Introduction: Stability or “Instability” Tests are an important tool for determining the likelihood of a slope to produce an avalanche. Many different tests have been developed over the years – each with their own strengths and weaknesses. These tests provide a way to safely apply stress and deformation to a slope that is steep enough to slide (usually 250 or steeper) and observe and quantify the results. These results

Although versed in philosophy and friends with many names we have already covered‚ he remained folksy.Here‚ we will consider Brâncuși’s First World War memorial at Tirgu-Jiu entitled The Endless Column. Yet‚ appreciating the subtlety of Brâncuși’s world heritage piece means attending to how Romanian folk and Orthodox religious ideas influenced him. Given Brâncuși’s humble upbringing and obvious love for all things Romanian‚ one cannot help wonder

Micro-extraction of urine and/or stomach contents and analysis by TLC Abstract Thin Layer Chromatography (TLC) is one of the oldest chromatographic techniques used for the identification of compounds and for determination of the presence of trace impurities. The aim of the experiment was to determine two unknown samples (X and Y) by comparing results to the known standard drugs‚ of which there was five‚ using a specific TLC method. The same technique was used for the determination of

Simple Distillation‚ Gas Chromatography: Preparation of Synthetic Banana Oil Introduction This experiment gave us the opportunity to work with a variety of new procedures as well as practice procedures that are new to us within the past few weeks of labs. Within the context of the scenario‚ we find that a distilling company that markets a popular banana liqueur is having problems. The banana plantation that they use to create their banana extract was hit hard by a hurricane and their reserves

Title Identification of Analgesic Compounds Using Thin Layer Chromatography Abstract The objective of laboratory experiment six was to identify an unknown analgesic tablet using Thin Layer Chromatography (TLC) analysis. The procedure involved preparing TLC plates‚ solubilizing standard analgesics (ibuprofen‚ aspirin‚ acetaminophen‚ caffeine) and the unknown in isopropyl alcohol (IPA)‚ and developing the plates in acetone. Rf values were calculated for each compound. The unknown tablet showed an Rf

Alkaline Phosphatase was isolated using various techniques. BCIP spot test was performed after the anion exchange chromatography was done and the fractions were collected. The picture of BCIP spot test of the 20 fractions can be seen in figure 1. The intensity of each spot was different from each other. The more intense color the spot was‚ the more concentrate the AP was. The fractions were chosen to combine together based on the intensity‚ which made the stage 4 enzyme. Different volumes in each

In the story‚ “This Was Supposed to Be My Column for New Year’s Day”‚ it says‚ “Dr. Perry was a self-hating procrastinator until it occurred to him in 1995 he was not entirely lazy.” Even when he would put things off‚ he would still do little things. Actually‚ doing little things can lead up to doing the important task one is supposed to be working on. Procrastinating‚ which is putting things off until last minute‚ may seem like a harmful tool‚ but it actually isn’t all that harmful. It may actually
