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

INTRODUCTION: Carbohydrates are the product that made up from carbon‚ hydrogen and oxygen. Carbohydrates are form by the combination of carbon dioxide and water molecules. The carbohydrates contain two specific functional group in it which is the hydroxyl groups and carbonyl groups.A reducing sugar is a type of sugar with is an aldehyde group.This means that sugar can act as a reducing agent.The procces of reducing sugar is isomerisation‚example of reducing sugar islactose

imply the non-stationarity of the linear combinations of these series. Hence‚ it is a prerequisite to ensure that all variables are integrated of order one in levels before employing the panel cointegration tests. Table 3 presents the results performed by Im‚ Pesaran and Shin unit root test of all variables for the four panels of economies tested in both levels and in first difference. Panel A‚ B‚ C and D represents all income economies‚ high-income economies‚ upper-middle-income economies and

TRIPLE SUGAR-IRON AGAR TEST Triple sugar-iron (TSI) agar test- designed to differentiate among the different groups or genera of the Enterobacteriaceae‚ which are all gram-negative bacilli capable of fermenting glucose with the production of acid a. Differentiation is made on the basis of differences in carbohydrate fermentation patterns and hydrogen sulfide production. To facilitate observation of carbohydrate utilization patterns- TSI agar slants contain lactose and sucrose (1%) concentrations

Summer Mitchell 10/04/13 Analysis and Conclusion 1. Why was the water tested for each of the initial chemical tests? The water was tested for each initial chemical test because it served as the controlled variable. Since water is pure oxygen and hydrogen unlike Glucose and Starch‚ one variable may be observed. 2. Biuret reagent will turn your skin brownish-purple. Explain why this occurs. Biuret reagent will turn your skin a brownish-purple because Iodine detects protein in a substance

ntroduction The purpose of this experiment was to use Iodine‚ Benedict and Biuret to test the reaction of the following 12 samples: 1% glucose‚ 0.3% glucose-1-phosphate‚ 1% maltose‚ honey‚ 1% sucrose‚ 1%lactose‚ 1% glycogen‚ 1% starch‚ protein‚ beer‚ distilled water and an unknown solution (test tube: 300). The iodine test for starch was to test how would starch reacted if we put iodine in it. The color of starch before the test was clear. The color of the iodine was brown. When you added iodine into starch

Test-driven development cycle A graphical representation of the development cycle‚ using a basic flowchart The following sequence is based on the book Test-Driven Development by Example.[1] 1. Add a test In test-driven development‚ each new feature begins with writing a test. This test must inevitably fail because it is written before the feature has been implemented. (If it does not fail‚ then either the proposed "new" feature already exists or the test is defective.) To write a test‚ the

EXPERIMENT No.25BACILLUS: Diagnostic Tests | | ASCOLI’S THERMOPRECIPITIN TEST Purpose: used to identify anthrax bacilli in animal hides and meat. Principle: This test was designed to detect B. anthracis antigens in the tissues of animals being utilized in animal by-products and thereby to reveal when these products contained ingredients originating from animals that had died of anthrax. The thermostable antigens involved are common to other Bacillus species so the test depends on the fact that the
