Failure Of Opioids To Modify Noradrenergic Neuronal Recovery From A Dorsal Bundle Lesion In Neonatal Rats, Ellen L. Kunkel-Bagden May 1985

Failure Of Opioids To Modify Noradrenergic Neuronal Recovery From A Dorsal Bundle Lesion In Neonatal Rats, Ellen L. Kunkel-Bagden

Electronic Theses and Dissertations

Morphine and exogenous opioid peptides alter the development of central noradrenergic neurons damaged by neonatal treatment with the neurotoxin 6-hydroxydopa. Transection of the dorsal noradrenergic bundle (DNB) in neonatal rats produces nearly the same alteration in the developmental pattern. It was of interest to determine whether morphine or an exogenous opioid peptide (metenkephalin) was able to modify the recovery of noradrenergic neurons after neonatal surgical transection of the DNB. Neonatal rats were divided into two groups. Both groups received saline (0.85%) or naloxone (2.0 mg/kg) by the intraperitoneal (i.p.) route. In the first group the animals received an additional i.p. …

Spatial Perception As A Predictor Of Success In Higher Mathematics, Lou A. Rolen

Electronic Theses and Dissertations

The problem of this study was to determine if spatial perception could be a predictor of success in higher mathematics. This study first showed correlations of the results of three spatial perception tests taken by high-school students with their final geometry grades. Structure of the Intellect-Learning Ability subtests CFS (cognition of figural systems) and CFT (cognition of figural transformations), as well as Differential Aptitude Tests-Space Relations subtest, were used. Correlations were then computed for high-school geometery grades with calculus I grades. Geometry thus was used as a bridge between spatial perception and calculus performance. Secondly, the investigator explored any difference …

Human Lung Tryptase Purification And Characterization, Timothy J. Smith May 1985

Human Lung Tryptase Purification And Characterization, Timothy J. Smith

Electronic Theses and Dissertations

Human lung tryptase (HLT), a mast cell derived trypsin-like enzyme, was isolated from whole human lung tissue obtained at autopsy. Increased yields from this purification process allowed extensive characterization of the enzyme. One of the critical steps in the purification scheme was the use of a linear heparin gradient to elute active material from cellulose phosphate. Gel filtration studies in 1.0 M NaCl yielded an apparent M(,r) of 135,000, and subsequent electrophoresis on sodium dodecyl sulfate-polyacrylamide gels demonstrated the presence of two active species with apparent M(,r) = 30,900 and 31,600. Enzymatic activity was sensitive to NaCl concentrations above 0.05 …

Effect Of Ethephon On Yield Components And Morphology Of Irrigated Spring Wheat, Brian C. Winberg Apr 1985

Effect Of Ethephon On Yield Components And Morphology Of Irrigated Spring Wheat, Brian C. Winberg

Electronic Theses and Dissertations

The number of irrigated acres in South Dakota is approximately 0.5 million acres. Water development plans could increase irrigated acreage four to five times causing an additional demand for electricity. Utilities pay more for electricity used during peak demand and this cost is passed on to consumers. To evenly distribute demand, some utilities are experimenting with irrigation scheduling to avoid peak usage during the day and offering lower electrical rates to participants. Another method to distribute electrical demands could be growing a crop with lower water requirements or one which has requirements earlier in the growing season and matures before …

Effects Of Various Dietary Salt Additions On Silica Urolithiasis In Male Rats, Carl J. Schreier

Electronic Theses and Dissertations

Urinary calculi composed primarily of silica have been identified in range animals by several researchers. Silica calculi have also been found in dogs, humans, rats and guinea pigs. Forman et al conducted a detailed analysis of calculi. They found.that ashing at temperatures of 1500 C decreased calculi weight by 20%. Silica and calcium were shown to make up most of the remaining mineral content. Calculi from grazing ruminants in western Australia contained Si02, but further analysis showed that they were a mixture of substances. Mcintosh found that of the calculi analyzed 47% contained weddelite (Calcium oxalate.H20) and opaline silica, 13% …

Ozonation And Manganese Greensand Filtration For Iron And Manganese Removal From A Municipal Groundwater Supply, Cary Pieterick Apr 1985

Ozonation And Manganese Greensand Filtration For Iron And Manganese Removal From A Municipal Groundwater Supply, Cary Pieterick

Electronic Theses and Dissertations

Stoebner and Schjodt both used a pilot plant which treated raw water with ozone gas for the oxidation of iron am manganese and then passed the treated water through an anthracite coal filter. Both agree that the degree of iron and manganese oxidation was greatly affected by changes in ozone dosage but was not greatly affected by changes in detention time. Both also experienced limited filter runs between backwashing because of iron and manganese breakthrough in the filter effluent. Kirscherman used a pilot plant that involved aeration, potassium permanganate (KMnO4) treatment, basin detention, and filtration through a dual media (manganese …

William Kloefkorn : His Works And His Women, Jane Jensen Pierce Apr 1985

William Kloefkorn : His Works And His Women, Jane Jensen Pierce

Electronic Theses and Dissertations

Kloefkorn's poetry explores the relationship between people and their land, an integral part of the psyche of a people whose livelihood depends upon this relationship. His first book of poetry, Alvin Turner As Farmer, deals almost entirely with learning to live with the land instead of trying to dominate it. After writing poetry on other subjects, Kloefkorn returns to this theme in Platte Valley Homestead, his eleventh collection, as he incorporates both the river and the land as learning experiences for the Midwestern farmer. In other collections, he goes beyond farm people and writes of small-town life, especially as it …

The Effects Of Biological Type And Breed Composition On Production In Beef Cattle, Michael D. Monfore Apr 1985

The Effects Of Biological Type And Breed Composition On Production In Beef Cattle, Michael D. Monfore

Electronic Theses and Dissertations

Evaluation of breeds has developed beyond simple phenotypic performance comparisons to estimation of the various genetic components, additive and nonadditive, contributed by a breed (Dickerson ,1969). Alenda et al.; Dillard et al. and Robison et al. demonstrated methods for estimating breed genetic and maternal effects in crossbred populations. Alenda and Martin extended the use of regression models to allow estimation of optimal breed combinations. This procedure, based on work by Dickerson, involves construction of a mathematical model describing performance for a trait as the sum of breed additive, breed heterotic, breed maternal and maternal heterotic effects. Crossbreeding results have been …

Effects Of Erosion On The Productivity Of Two Ustolls, Christopher F. Miller Apr 1985

Effects Of Erosion On The Productivity Of Two Ustolls, Christopher F. Miller

Electronic Theses and Dissertations

Soil productivity is defined as the capacity of a soil to produce a specified plant or sequence of plants under a particular management system. Soil erosion is a threat to our agricultural productivity. Soil loss seldom improves the capacity of the affected soil to produce crops and often reduces the long-term crop production potential of that soil. It is estimated that 181 million acres of our nation’s 413 million acres of cropland are susceptible to erosion exceeding tolerable soil loss levels (T-values). This amount will continue to increase as more marginal land is put into production. However, the degree to …

Freezing Resistance In Corn (Zea Mays L.), Richard Lee Luhman

Electronic Theses and Dissertations

Corn (Zea Mays L.), an annual crop, can be severely damaged by late spring frosts. Damage would be especially critical if the growing point were killed. To decrease the possibility that corn may be subjected to freezing conditions, shorter season corn could be planted later in the year. Another possibility, however, would be to develop varieties which could withstand freezing conditions. Due to the problem of spring frosts, the following research was performed with the long range goal of releasing a freeze resistant corn line. The initial stages of the research were to develop a method for screening corn inbred …

The Effect Of Photoperiod, Ergocryptine Injection And Melatonin Feeding On Reproduction In The Ewe, Cindie Marie Luhman Mar 1985

The Effect Of Photoperiod, Ergocryptine Injection And Melatonin Feeding On Reproduction In The Ewe, Cindie Marie Luhman

Electronic Theses and Dissertations

One of the most intriguing aspects of reproduction is the reversible fertility governing seasonal breeding. Sheep are one of the many species that exhibit a circannual rhythm in reproduction, because they start estrous cycles in fall and winter months and become anestrus in spring and summer months. Seasonal changes appear to control this. Ewes seem to be more completely seasonal than are rams because only very limited ovarian activity, fewer follicles, and no ovulation occurs in ewes, although follicular size remains unchanged. Most rams will produce viable semen throughout all seasons, however, Lincoln and Short and Almeida and Lincoln reported …

Modification Of The Ackers And White Transport Equation To Permit Calculation By Size Fractions, Jeff A. Lewandowski Mar 1985

Modification Of The Ackers And White Transport Equation To Permit Calculation By Size Fractions, Jeff A. Lewandowski

Electronic Theses and Dissertations

Sediment transport is a phenomenon which must -be taken into account when an engineering project includes or influences a natural channel. Most notable of these projects are reservoirs, river training structures and bridge piers. The useful life of a reservoir is directly the amount of sediment transported in a river. River training structures affect the acceleration of the flow and cause scour or deposition dependent on design. Bridge piers which are not properly designed can also cause the same accelerations causing deposition or, in a worst case, scour, threatening the pier and bridge. The design of earthen channels must take …
