Green-Ampt Infiltration Model Parameter Determination Using Scs Curve Number (Cn) And Soil Texture Class, And Application To The Scs Runoff Model, Elena Viktorovna Brevnova

Graduate Theses, Dissertations, and Problem Reports (ETD)

The U.S. Department of Agriculture (USDA) Soil Conservation Service Curve Number (SCS CN) method is a simple and widely popular technique of estimation of direct runoff volume for design and natural rainfall events in small watersheds. The SCS CN procedure is incorporated into such computer programs as TR-20 and TR-55. Although the method reliably predicts 24-hr runoff volume, the predicted distribution of runoff during a storm event is not realistic. This shortcoming of the SCS CN method is due to weakness in the infiltration concept of the method. Use of a physically realistic and distributed Green-Ampt infiltration model can significantly …

Development Of A Micro-Dilution Tunnel System For In-Use, On-Board Heavy-Duty Vehicle Particulate Matter Emissions Measurement, Emily Deanna Cirillo Aug 2001

Development Of A Micro-Dilution Tunnel System For In-Use, On-Board Heavy-Duty Vehicle Particulate Matter Emissions Measurement, Emily Deanna Cirillo

Graduate Theses, Dissertations, and Problem Reports (ETD)

A novel portable particulate matter measuring system was designed, developed and qualified. The heavy-duty engine Federal Test Procedure (FTP) requires the use of a full-flow tunnel to measure particulate emissions from diesel fueled engines. However, a full-flow tunnel based constant volume sampler (CVS) system is not only expensive to build and maintain, it also requires a large work space. The portable micro-dilution system that could be used for measuring on-board, in-use emissions from heavy-duty vehicles would cost significantly less. The micro-dilution tunnel operates on the same principle as a full-flow dilution tunnel. The added advantage of the proposed design is …

Seasonal Plasticity Of A15 Dopaminergic Neurons In The Ewe, Van Lee Adams Aug 2001

Seasonal Plasticity Of A15 Dopaminergic Neurons In The Ewe, Van Lee Adams

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the ewe, anestrus is caused by increased sensitivity to E2 negative feedback that is mediated by A15 dopaminergic neurons that are only responsive to E2 in anestrus. Experiment 1, tested the hypothesis that synaptic input on A15 neurons varies with season by examining synapsin-positive close contacts on A15 cells using immunofluorescence and confocal microscopy. The number of contacts on dendrites, but not somata, increased during anestrus. There were also corresponding changes in dendritic morphology including an increase in dendritic length, surface area, and number of bifurcations. Because thyroid hormones are necessary for the transition to anestrus, we next examined …

Effect Of Concentrations Of Progesterone On Follicular Development And Fertility In Beef Cows, Jason Brian Candler Aug 2001

Effect Of Concentrations Of Progesterone On Follicular Development And Fertility In Beef Cows, Jason Brian Candler

Graduate Theses, Dissertations, and Problem Reports (ETD)

The present study was performed to investigate the effects of low ascending concentrations of progesterone on fertility in lactating beef cattle. Cows on the low ascending progesterone treatment received PGF2alpha from days 3 to 4 after estrus. All cows received PGF2alpha on day 9, and estradiol benzoate on day 11. Cows were inseminated artificially 12 hours after estrus. Concentrations of progesterone were lower in treated versus control cows. Pregnancy rate did not differ between treated and control cows. Pregnancy rate was greater in cows that ovulated a follicle from the right (78%) versus left (52%) ovary (p < 0.01). Low ascending progesterone early in the estrous cycle did not decrease fertility to the same extent seen with extended periods of low progesterone.

Graduate Theses, Dissertations, and Problem Reports (ETD)

A derivative of 4H-cyclopenta[def]phenanthren-4-one, 51, was synthesized from the protected ninhydrin 54 and 2 equivalents of 1-(2-ethynylphenyl)-2-phenylethyne. Condensation of the diketone 54 with the lithium acetylide 55 furnished the trans propargylic alcohol 56a and the cis propargylic alcohol 56b. Treatment of 56a with thionyl chloride promoted a sequence of reactions presumably with an initial formation of the chlorinated benzoenyne-allene 58. Two cycles of a C2--C6 biradical cyclization reaction followed by a radical-radical coupling then afforded the formal [4+2] Diels-Alder cycloaddition adduct 60, which in turn underwent tautomerization to give 61. Reduction with tri-n-butyltin hydride then gave the ketal 62 in …

Integrated Modulation Of Sympathetic Tone In The Microcirculation By Oxygen, Adenosine, And Nitric Oxide, Bryan Auston Sauls Aug 2001

Integrated Modulation Of Sympathetic Tone In The Microcirculation By Oxygen, Adenosine, And Nitric Oxide, Bryan Auston Sauls

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite a profound reduction in hemodynamic shear stress, a sustained release of endothelium-derived nitric oxide (NO) limits arteriolar constriction during periods of increased sympathetic nerve activity in the rat small intestine. In this project, we sought to test the hypothesis that adenosine, formed in response to a flow-dependent fall in local PO2, serves as the stimulus to preserve endothelial NO release under these conditions. Sympathetic nerve stimulation induced frequency-dependent arteriolar constrictions and a flow-dependent fall in local PO2. The arteriolar responses to nerve stimulation were enhanced after inhibition of NO synthase with NG-monomethyl-L-arginine (L-NMMA). Under a high (20%) O2 superfusate, …

The objectives of this study were to determine the effect of the crosslink breaker ALT-711 on the concentration of soluble collagen, as well as its effectiveness on meat tenderness.;Final body weights were not affected by treatments. Muscle tenderness was higher (p < 0.05) for TB, SS, BF, ST, and LT (p < 0.10) for A-maturity animals compared to control and ALT-711 treated animals. No consistent ALT-711 effect on shear force measurements was found. Shear force increased linearly with age BF, R2 = 0.94; SM, R2 = 0.81; LL, R 2 = 0.77; SS, R2 = 0.63; LT, R2 = 0.32; TB, R2 = 0.37; ST, R2 = 0.40. Total collagen content was not different (p > 0.10) between A-maturity, control and ALT-711 treated animals. However, the concentration of soluble collagen was higher (P < 0.05) for A-maturity group. Insoluble collagen content was higher (p < 0.05) for longissimus thoracis, biceps femoris, and (p < 0.10) for supraspinatus of control animals. Muscle soluble collagen content decreased linearly as chronological age increased LT R2 = 0.98; LL R 2 = 0.92; TB R2 = 0.99; BF R2 = 0.99; ST R2 = 0.95; SM R2 = 0.99; SS R2 = 0.36. The soluble collagen percentage was higher for ALT-711 treated animals compared to control animals.;ALT-711 tended to increase muscle soluble collagen content of aged cattle. ALT-711 may be an effective age-related collagen crosslink breaker. However, ALT-711 may not be used to improve meat quality of aged cattle.
