Some Physical And Chemical Properties Of Pine Bark Growing Medium Used As An Evaluation Of Its Nutritional Status., Don Christy Wilkerson Jan 1981

Some Physical And Chemical Properties Of Pine Bark Growing Medium Used As An Evaluation Of Its Nutritional Status., Don Christy Wilkerson

LSU Historical Dissertations and Theses

Various physical and chemical analyses were conducted on southern pine bark. The results from these analyses were then examined in terms of their effect on the interpretation of substrate fertility. The drainage aeration and water holding capacity of pine bark was found to be suitable for use as a container medium. Also the determination of the pH, CEC, and "available" nutrient content of pine bark indicated acceptable levels for plant growth. However, all values were dependent on the method of analysis. In general, it was concluded that a complex relationship exists between the physical and chemical properties of pine bark. …

The Biology Of Beggiatoa., William Roy Strohl Jan 1980

The Biology Of Beggiatoa., William Roy Strohl

LSU Historical Dissertations and Theses

Part I. An accurate most-probable-number enumeration method was developed for counting the number of Beggiatoa trichomes from various freshwater sediments. The medium consisted of extracted hay, diluted soil extract, 0.05% sodium acetate, and 15-35 units per ml of catalase. The same enrichment medium, but without the acetate, was the best enrichment medium from which to obtain pure cultures. A total of thirty-two strains of Beggiatoa were isolated from seven different freshwater habitats and were separated into five groups based on several preliminary characteristics. Four of the groups contained cells with trichomes of approximately the same diameter (1.5-2.7 (mu)m) and may …

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 …

The Association Between Urinary Sodium Excretion And Blood Pressure In Children, R. Cooper, I. Soltero, K. Liu, D. Berkson, S. Levinson, J. Stamler Jan 1980

The Association Between Urinary Sodium Excretion And Blood Pressure In Children, R. Cooper, I. Soltero, K. Liu, D. Berkson, S. Levinson, J. Stamler

Faculty Publications

This study explored the association between sodium excretion and blood pressure (BP). A new method was used to minimize the measurement error introduced by the large intrinsic variability of 24-hour sodium excretion. The ratio of intra- to interindividual variation was used to estimate the number of measurements needed to characterize the individual. When seven consecutive 24-hour samples were collected from 73 children, ages 11-14 years, a significant correlation between mean individual sodium excretion and BP was demonstrated. The independent relationship persisted when controlling for height, weight, pulse, age, sex and race (p = 0.045), but was eliminated by simultaneously considering …

Effects Of Flooding Dates And Disposals Of Rice Straw On Crayfish, Procambarus Clarkii (Girard), Culture In Rice Field., Yew-Hu Chien Jan 1980

Effects Of Flooding Dates And Disposals Of Rice Straw On Crayfish, Procambarus Clarkii (Girard), Culture In Rice Field., Yew-Hu Chien

LSU Historical Dissertations and Theses

Studies were conducted to determine the effects of flooding dates and different disposals of rice straw on crayfish culture in rice field. Nutritional composition of decayed rice straw, periphyton growth, and water quality were also determined. Eighteen earthen ponds were randomly assigned to six treatments in a two by three factorial arrangement: early flooding (20/Sept/1978), late flooding (15/Oct/78), and aerobic (baled), anaerobic (disked), partially aerobic (standing) decomposition of rice straw with three replications each. The average crayfish production in early-flooded ponds (1183 kg/ha) did not differ significantly from that in late-flooded ponds (1127 kg/ha). Significant differences (P < 0.05) in average crayfish production were found between standing ponds (1506 kg/ha) and disked ponds (803 kg/ha), and between baled ponds (1157 kg/ha) and disked ponds. The average crayfish production in standing ponds was not significantly higher than in baled ponds. von Bertalanffy's growth model revealed that all crayfish in early-flooded ponds attained an average maximum length (1(,00)) and Brody's growth coefficient (k) of 92.2 mm and 0.55, respectively, whereas all crayfish in late-flooded ponds had an 1(,00) and k of 82.7 mm and 0.09. Crayfish in disked ponds showed the poorest growth of all treatments. Late-flooded ponds had a higher population density than early flooded ponds. The population density was highest in baled ponds followed by standing and disked ponds. The harvestable crayfish size (total length > 75 mm) in …
