3-2-3-1-Conventional Culture Method (Marks 1972): The infected lesions of the tuberculin positive reactors were collected and placed in to a sterile mortar containing sterile sand. The fat was removed and the suspected parts were cut into minute pieces. Then 2 ml of distilled water added to the mixture‚ homogenized and crushed well until the suspension was obtained. Then 2 ml of H2So4 acid 4% added to the mixture then incubated the mixture at 37 0C for 1/2 h. The mixture was diluted with

The Knoevenagel Condensation Preparation of Ethyl 3-Coumarincarboxlate Ivy Akatsa Organic Chemistry Introduction Knoevenagel Condensation uses a compound of the type X-CH2-Y as the carbanion source‚ where X and Y are the electron withdrawing groups such as –CN‚-COOR‚-COR‚ NO2‚ etc. These groups are capable of stabilizing an adjacent carbanion by resonance. So in this experiment‚ the Knoevenagel Condensation of diethyl malonate with aromatic aldehyde salicylaldehyde involves an initial

Ethyl Acetate – NaOH Reaction Kinetics Experiment Martin Novick Group 14‚ Chemical Engineering Laboratory Submitted to Prof. David B. Henthorn September 25‚ 2012 Summary The goal of this project was to determine the pre-exponential factor‚ k o ‚ the activation energy‚ E‚ and the reaction rate constants‚ k‚ of the saponification process of ethyl acetate using sodium hydroxide (NaOH) at 5 temperature between 15 and 25 degrees Celsius. Two trails were performed at temperatures 16‚ 18‚ 20‚ 22‚ and 24

by using oxidation reduction and recording the observations‚ these tests will help determine the specific qualities each solution has. Hypothesis I theorize that nothing will happen with Magnesium because it is such a soft metal. Zinc should turn a greener color‚ because that’s what happens to a lot of statues and sculptures. I theorize that iron will tarnish badly because in air it can get tarnished so oxidation must do something as well. Materials 1 Paper towels 1 Well-Plate 1 Tweezers

An Oxidation-Reduction Scheme Nicolas Gibson Lab Time: Tuesday 11:30 am Abstract: In this experiment‚ the main objective was to synthesize a ketone from borneol via an oxidation reaction and secondly‚ to produce a secondary alcohol from camphor via a reduction reaction. Therefore‚ the hypothesis of this lab is that camphor will be produced in the oxidation reaction and isoborneol will be the product of the reduction reaction because of steric hindrance. For the oxidation step

mother; after that you may go in to her and be her husband‚ and she shall be your wife. These steps as seen in Deut 21:13 bear striking similitude to Hosea 3. First‚ the woman must remove the “clothes of her captivity.” Though there is no verbal parallel to Hosea 3 here‚ it is interesting to note that both Gomer (cf. Hosea 1:9; 3:1-2) and Israel (Hosea 2:11-17) appear to be banished from their homes as part of their initial judgment‚ and thus in a sense their restoration begins from “captivity.” The next

Chapter 3 Part 1 of 3 1) Identify and describe the two major sources of current liabilities. The two major source of liabilities‚ for both current and noncurrent liabilities‚ are operating and financing activities. Current liabilities of an operating nature—such as accounts payable and operating expense accruals—represent claims on resources from operating activities. Current liabilities such as notes payable‚ bonds‚ and the current maturities of long-term debt reflect claims on resources from financing
