Studies On The Physiology Of A Cellulolytic Strain Of Aspergillus Terreus Under Conditions Of Batch And Continuous Cultivation., Thomas Ferrell Miller Jan 1980

Studies On The Physiology Of A Cellulolytic Strain Of Aspergillus Terreus Under Conditions Of Batch And Continuous Cultivation., Thomas Ferrell Miller

LSU Historical Dissertations and Theses

Experiments have been conducted to determine the feasibility of the bioconversion of cellulose into Single Cell Protein (SCP) using a thermotolerant, cellulolytic strain of Aspergillus terreus. Crude cellulases produced during the growth of fungal biomass were tested for their ability to generate glucose syrups by enzymatic hydrolysis of cellulose. Studies on continuous cultivation of glucose-limited A. terreus resulted in the development of a highly optimized medium which allowed the organism to achieve similar maximum specific growth rates (umax) measured in batch culture. Upon proportionate increase of the medium composition, there was no decrease in growth rates or in biomass yields …

Cognitive Processes In Depression., Sally Ann Davis Jan 1980

Cognitive Processes In Depression., Sally Ann Davis

LSU Historical Dissertations and Theses

Hypotheses derived from Beck's cognitive theory of depression were tested using 60 depressed and non-depressed males and females as measured by the Beck Depression Inventory. Subjects rated their performance before and after they received "positive," "negative," and "neutral" feedback regarding their performance on a social interaction task. They were also asked to recall feedback they received and explain reasons for their post-feedback self-rating. Results showed depressed males and females had a more negative evaluation of present circumstances and poorer memory for feedback. Further, depressed males lowered their self-evaluation upon feedback significantly more than did non-depressed males. In addition, depressed males …

Hydroisomerization Of Pentane And Hexane Mixtures On Zeolite Catalysts., James Jerome Spivey Jan 1980

Hydroisomerization Of Pentane And Hexane Mixtures On Zeolite Catalysts., James Jerome Spivey

LSU Historical Dissertations and Theses

Pure component and mixtures of pentane and hexane were hydroisomerized on Pd-H-mordenite and Pd-H-faujasite at 465(DEGREES)F, 100 to 300 psig, 6.2 to 6.6 w/hr/w, and 10/1 to 18/1 H(,2)/hydrocarbon mole ratio. The activity of both these catalysts was comparable to other developmental catalysts reported in the literature. Results showed that on the mordenite catalyst, the first order rate constant for n-C(,5) decreased on dilution with n-C(,6) while the n-C(,6) rate constant increased on dilution with n-C(,5). On the faujasite catalyst, the rate constant for both n-C(,5) and n-C(,6) decreased from the pure component values on dilution. Models were proposed for …

Group Influence And Cognitive Consistency As Determinants Of Value Change: A Methodological Analysis Of Self-Confrontation Theory., Mark L. Paris Jan 1980

Group Influence And Cognitive Consistency As Determinants Of Value Change: A Methodological Analysis Of Self-Confrontation Theory., Mark L. Paris

LSU Historical Dissertations and Theses

The present study attempted to either extend, modify or challenge Rokeach's (1973) Self-confrontation theory of value change. Rokeach (1973) found that subjects who were confronted with specific self-confrontation messages, which were designed to make differences between their value systems and self-concepts salient, were more likely than control subjects to change the rank-ordering of the values Freedom and Equality in a ranking task containing 18 values. Rokeach explained this phenomenon by invoking the concept of self-dissatisfaction, which he said subjects came to feel as a result of being exposed to the self-confrontation messages. The present study compared this explanation with the …

The Piano Trio In London From 1791 To 1800., Howard Lee Irving Jan 1980

The Piano Trio In London From 1791 To 1800., Howard Lee Irving

LSU Historical Dissertations and Theses

The late piano trios of Joseph Haydn, which were published in London during his two trips there in 1791 and 1794, are neglected and misunderstood works. This study examines Haydn's late trios in the light of other works of the same type which were published for the same audience, in order to gain a clearer perspective of this repertoire. A variety of cultural and economic factors influenced the music considered in this study. In particular, the presence in London of a large class of affluent but relatively unsophisticated musical amateurs provided a lucrative outlet for composers who could satisfy the …

Development And Applications Of Gas Chromatography - Atomic Absorption Interface Instrumentation., Eric Leon Kiesel

LSU Historical Dissertations and Theses

It is being recognized that we are exposed to increasing numbers of poorly understood and potentially toxic substances within our environment. To understand fully the human health effects and environmental impact of these hazards, complete chemical characterization or "speciation" studies of these hazards is necessary. Once exposure to a toxic substance has occurred, the physical and chemical form will determine the length of time a compound will remain in the environment and the types of chemical reactions that will occur in atmospheric, aquatic, and soil environments. Physiological and toxicological effects are also dependent upon the chemical form and physical form. …

Selective Antagonism Of The Rate‐Decreasing Effect Of D‐Amphetamine By Chlorpromazine In A Repeated‐Acquisition Task, Donald M. Thompson Jan 1980

Selective Antagonism Of The Rate‐Decreasing Effect Of D‐Amphetamine By Chlorpromazine In A Repeated‐Acquisition Task, Donald M. Thompson

Faculty Publications

Pigeons acquired a different four‐response chain each session by responding sequentially on three keys in the presence of four colors. The response chain was maintained by food presentation under a fixed‐ratio schedule. When d‐amphetamine was administered alone, the overall response rate decreased and the percent errors increased with increasing doses. When a small dose of chlorpromazine, which was ineffective when given alone, was administered in combination with d‐amphetamine, the rate‐decreasing effect was antagonized. The antagonism was selective, however, in that the error‐increasing effect of d‐amprotamine was augmented by chlorpromazine. The nature of the joint effect of the two drugs thus …

Effects Of D‐Amphetamine And Cocaine On Strained Ratio Behavior In A Repeated‐Acquisition Task, Donald M. Thompson, Joseph M. Moerschbaecher Jan 1980

Effects Of D‐Amphetamine And Cocaine On Strained Ratio Behavior In A Repeated‐Acquisition Task, Donald M. Thompson, Joseph M. Moerschbaecher

Faculty Publications

Pigeons acquired a different four‐response chain each session by responding sequentially on three keys in the presence of four colors. When the fixed‐ratio requirement for food presentation was five completions of the chain, d‐amphetamine and cocaine disrupted the behavior. As the dose of each drug was increased, the overall response rate decreased, the overall accuracy was impaired (i.e., percent errors increased), and there was less within‐session error reduction (acquisition). In contrast, when the fixed‐ratio requirement was either 20 or 50 completions of the chain, certain doses of both drugs produced large increases in the overall response rate by eliminating the …

Effects Of D‐Amphetamine, Cocaine, And Phencyclidine On The Acquisition Of Response Sequences With And Without Stimulus Fading, Joseph M. Moerschbaecher, Donald M. Thompson

Faculty Publications

In each of three components of a multiple schedule, monkeys were required to emit a different sequence of four responses in a predetermined order on four levers. Sequence completions produced food on a fixed‐ratio schedule. Errors produced a brief timeout. One component of the multiple schedule was a repeated‐acquisition task where the four‐response sequence changed each session (learning). The second component of the multiple schedule was also a repeated‐acquisition task, but acquisition was supported through the use of a stimulus‐fading procedure (faded learning). In a third component of the multiple schedule, the sequence of responses remained the same from session …

A Survey Of Patterns Of Nonpharmacologic Care For Hypertensive Patients, Including Recommendations For Their Children, Ivan Soltero, Yi Tsong, Richard Cooper, Jeremiah Stamler, Rose Stamler, Dan Garside

Faculty Publications

To ascertain current approaches of physicians to nutritional-hygienic management of hypertensive patients and their children, a survey was done among a random sample of Chicago-area generalists, internists, and cardiologists. Thirteen items related to advice for patients; two for their children. Of 713 physicians holding M.D. degrees in the sample, 573 (80%) responded. For hypertensive patients, the great majority of physicians indicated that they advise weight loss, avoidance of salt use at table, no smoking, regular exercise, limitation of alcohol intake, and avoidance of stressful situations. Although 98% advised weight loss, a minority responded positively to reduction of carbohydrate and/or fat …
