Methods Of Investigation For The University Of Alabama

Purpose: To become familiar with the International System of Units and common laboratory equipment and techniques. To learn how to determine volume, mass, length, and temperature of a wide variety of items. To learn how to calculate density and concentration of dilutions.

Censoring Science begins in Washington D.C., where we are introduced to Dr. James Hansen. Born in 1941 on a farm in Denison, Iowa, Jim was the fifth child and first boy out of seven children. His father, who had minimal education, held many different low-paying jobs and the family moved rather frequently. In third grade, Jim’s sister gave him part of her paper route- a job he would keep throughout high school, gradually saving up enough money to pay for college. Though he was a rather laid-back student, he earned the highest score on an IQ test (taken by seventh-twelfth graders) in seventh grade. Because of his test scores Jim received a scholarship to the University of Iowa, where he came under the

To design and carry out a certain experiment, one should follow some crucial steps. These steps holistically make up a systematic process called the scientific method (Penn State Science, 2008). The scientific method involves the recognition of a problem, compilation of background research, formulation of a hypothesis, design and conduction of an experiment, interpretation of a conclusion, and discussion of future implications of the investigation (Hess, 2011). Overall, this is a fundamental outline of how the experiment ought to be executed.

In one of the tubes the nutrient broth was used to see the amount of growth on the sediment, subsurface and surface of the tube. A nutrient agar was used to examine the growth’s form, color and opacity. Another method colony morphology was done to show the color, size, form, margin and elevation of the unknown culture #304. To determine the oxygen requirements for the organism a FTM was used. A gelatin stab was performed to observe if liquefaction would occur. This test will show if the unknown culture is gelatinous. The last test to see the cultural characteristics was done to see how tolerant the organism is to salt. Four agar plates were inoculated to see the different osmotic

Thirty two strains which showed high and medium growth ability at 55oC were retested at the same conditions, i.e. streptomycin supplementation and at 55oC, results are present in Table 12.

All above laws and regulations provide a detailed protocol to conduct the human research and how the privacy and confidentiality of the human subject can be protected. (Beskow et al., 2012; Perfetto et al., 2015)

The purpose of this experiment is to become familiar with the specific microbiological technique known as the aseptic technique, which is used to avoid contaminating cultures.

Parasitic nematodes cause diseases of major economic importance in sheep .The lungworm , Dictyocaulus filaria , represents one of these nematodes inhabits bronchi and bronchioles and cause parasitic bronchitis (commonly known as ‘husk) particularly in young sheep ( Holzhauer et al., 2011). Dictyocaulus filaria has direct life cycle, embryonated eggs are coughed up or swallowed and hatch in the small intestine then first-stage larvae are passed in faeces. Under favorable environmental conditions, first-stage larvae moult to second-stage larvae and then infective en-sheathed third-stage larvae that actively move from faeces to herbage and are ingested by the grazing sheep. Following ingestion, third-stage larvae ex-sheath in the small intestine, penetrate the intestinal wall and enter the mesenteric lymph nodes. Here, larvae develop,
