Intracellular Protein Degradation In A Mesophile And A Thermophile Of The Genus Bacillus, Cameron C. Hoover

Masters Theses

¹⁴C-leucine was incorporated into th e proteins of the mesophile Bacillus licheniformis and the thermophile Bacillus stearothermophilus. Aliquots of the cell suspension were treated with chloramine-T in order to decarboxylate the ¹⁴C-leucine that was released as the proteins degraded. The ¹⁴CO₂ was trapped and counted. This allowed for the determination of the extent of intracellular protein degradation at various tem peratures and at various stages of the growth cun/e. For the mesophile, the extent of degradation increased with temperature from 30° C to 55° C. For the thermophile, no significant amount of degradation occurred until …

An Analysis Of The Effects Of A Low Glycemic Diet On The Antisocial Behavior Of Juvenile Offenders, James Edward Longhurst

Dissertations

The objective of this study was to determine if a low glycemic diet contributes to a reduction in the incidence of antisocial behavior among male juvenile offenders.

One hundred forty juvenile offenders at a residential treatment center were randomly divided into treatment and nontreatment groups. The treatment group ate from a diet which contained foods low in glycemic characteristics. There was no dietary alteration for the control group.

Three instruments were used to measure differences between groups in antisocial behavior following a 5-week experimental period. These instruments include: (1) the Unusual Incident Report--a systematic and objective observer report form, (2) …

The Effect Of Anthraquinone In The Kraft Pulping Process, Carl W. Stoll

Paper Engineering Senior Theses

Due to current attitudes arid regulations concerning the odorous emission of mercaptans from the Kraft pulping process, new technology must be developed to enable the process to be run at lower sulfide levels. The use of cyclic-keto compounds, as pulping catalyst, could be a major step in the reduction of sulfide levels in Kraft pulping, while acting to increase the pulping yield through a mechanism that stabilizes the carbohydrates during the process and catalyzes delignification.

The objective of this research project is to evaluate the performance of one cyclic keto compound that has recently received the attention of many researchers …

The Effects Of Oil Well Sites On Forest Species Of Birds, Wendy J. Baker

Masters Theses

Fifty censuses were taken in 9 transects adjacent to 8 oil well openings. It was found that 2 species, the red-eyed vireo (Vireo olivaceus), and the ovenbird (Seiurus aurocapilus) were significantly affected in spatial distribution. These forest species had significantly lower numbers near the oil well site than in the forest. Two other forest species suggested the same pattern. The effect of the oil well site reaches well into the forest.

Other possible effects of the oil well sites are competition with edge species and brood parasitism by the brown-headed cowbird. Noisier sites may also affect the bird community within …

The Application Of Chitosan To Composite Boxboard For Plybond Development, Tracy O. Drier

Paper Engineering Senior Theses

The area of study during this research was the effect of the marine polymer chitosan addition rate on strength properties, and retention characteristics. Two machine trials were run on the WMU twin ply former using old corrugated container (O.C.C.).

Machine run # 1 consisted of running a 1% chitosan solution at 0, 6, 16, 18#/ton. Run # 2 also used a 1% chitosan solution but lower addition rates of 0, 2, 5#/ton. The chitosan was added to the thick stock prior to the fan pump for both runs. No comparisons between the runs were made.

Conclusions from both runs include: …

The Effect Of Film Forming Agents In A Size Solution On Silicone Holdout, Michael D. Stang

Paper Engineering Senior Theses

In the production c>f base papers for silicone coating, one of the most important variables is the holdout capability of the ' base sheet. The holdout is primarily affected by the surface characteristics of the sheet relating to the smoothness and surface structure.

An experiment was designed to look at the effects of several different commercial film forming agents in a standard size solution on the holdout properties of the sheet. A laboratory size press coater was assembled and used for application of the size solutions. After supercalendering, the sheets were silicone coated with an aqueous silicone solution and …

Reaction Of 2,2,6-Trimethyl-1,3-Dioxin-4-One With Isocyanate Derivatives And The Synthesis Of 2,3,4,6-Tetra-O-Acetyl-Dglucopyranosyl Phenyl Carbodiimide, Tung Van Le

Masters Theses

This research was undertaken to study the synthesis and reactions of isocyanates with diketenes, the synthesis of glycosyl carbodiimide.

The 1,3-oxazine-2,4-dione compounds could be useful in the medicinal chemistry field and the agricultural field, the research using glycosyl carbodiimide as a synthon shows great promise for the medicinal chemistry field.

Production Of Thymine Dimer In Dna From Mesophilic And Thermophilic Bacteria By Uv Irradiation, F Redrick Shu-Chung Yein

Dissertations

The in vitro production of thymine dimer (TT) in DNA, isolated from the mesophile (B. licheniformis) and the thermophile (B. stearothermophilus), was carried out by UV irradiation (254 nm) at three different temperatures (35, 45, and 55(DEGREES)C). The production of TT from the thermophilic DNA was significantly higher than that from the mesophilic DNA. This was the case at all three irradiation temperatures. The increase in TT production per 10(DEGREES)C increase in irradiation temperature was four times higher for the thermophile than that for the mesophile. It was concluded that the DNA from the thermophile was photochemically less stable than …
