Historical Water Use Backcasting Study Luke Air Force Base, Arizona, Mohamed A. Hegazy, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

The goal of this report is to present historic (backcast) water use for Luke Air Force Base (LAFB), Arizona for 1941 through 1961. Historic water use (including system losses) from LAFB records can be used as groundwater pumping amounts because groundwater extracted from the underlying aquifer was the sole water source. Historical water use amounts were derived primarily using regression analysis and the Installation Water Resources Analysis and Planning System - Air Force (IWRAPS-AF). IWRAPS-AF is a computer software package designed to forecast or backcast water use and assess the effectiveness of conservation measures at Air Force Installations (Willett et. …

The Fate And Disposition Of Metolachlor And 2, 4-D Under Irrigated Corn And Turf, Ghassan R. Musharrafieh, Richard C. Peralta, Robert W. Hill, Howard M. Deer

Civil and Environmental Engineering Faculty Publications

A field lysimeter experiment was conducted during the summers of 1993 and 1994, at the River Laboratory, Utah State University, Logan, Utah. The intent was to study the fate and disposition of metolachlor and 2,4-D in a one dimensional soil system. Metolachlor was applied to corn and 2,4-D was applied to turf. The mobility, persistence, and degradation of these herbicides were investigated in the field lysimeters using four irrigation treatment levels on corn and two irrigation levels on turf. The four irrigation levels applied to corn were 0, 30, 60, and 120 percent of potential evapotranspiration. The two irrigation levels …

The Existing Indian Family Exception: Denying Tribal Rights Protected By The Indian Child Welfare Act, Wendy Therese Parnell

San Diego Law Review

The Indian Child Welfare Act (ICWA), the author argues, was designed to prevent the removal of Indian children from their tribal culture. This was accomplished by providing minimum standards for removing Indian children from their homes, and by placing removal decisions within tribal jurisdiction. Courts, however, have applied an "existing Indian family" exception to the ICWA. This exception limits the application of the ICWA to cases where the Indian child is to be removed from an "existing Indian family," which excludes many removal cases, such as those where the child does not have a sufficient bond with an Indian parent. …

Functional Analysis Of Surfactant Protein B (Sp-B) Promoter. Sp1, Sp3, Ttf-1, And Hnf-3Α Transcription Factors Are Necessary For Lung Cell-Specific Activation Of Sp-B Gene Transcription, Ramgopol K. Margana, Vijayakumar Boggaram

School of Medical and Biological Sciences Faculty Publications and Presentations

Surfactant protein B (SP-B) is essential for maintenance of biophysical properties and physiological function of pulmonary surfactant. SP-B mRNA expression is restricted to alveolar type II epithelial cells and bronchiolar epithelial cells (Clara cells) of adult lung. We previously (Margana, R. K., and Boggaram, V. (1996) Am. J. Physiol. 270, L601-L612) found that a minimal promoter region (-236 to +39) of rabbit SP-B gene is sufficient for high level expression of chloramphenicol acetyltransferase reporter gene in NCI-H441 cells, a cell line with characteristics of Clara cells. In the present study we used mutational analysis, electrophoretic mobility shift assays, and DNase …

Bilinear Time-Frequency Representations Of Heart Rate Variability And Respiration During Stress, Rindala Saliba

Dissertations

Recently, joint time-frequency signal representation has received considerable attention as a powerful tool for analyzing a variety of signals and systems. In particular, if the frequency content is time varying as in signals of biological origin which often do not comply with the stationarity assumptions, then this approach is quite attractive. In this dissertation, we explore the possibility of better representation of two particular biological signals, namely heart rate variability (HRV) and respiration. We propose the use of time-frequency analysis as a new and innovative approach to examine the physical and mental exertion attributed to exercise. Two studies are used …

Two Dimensional Agonistic Control, Daqing Yang

Dissertations

The conventional method of precise multiple-axis motion control entails use of a multiple axis positioning system with each axis carrying not only the workpiece but also the positioning system of the remaining axes. The resultant structure is heavy, sluggish, and expensive. An alternative positioning technique is being investigated in which the motion of the workpiece is controlled by pulling it with tendons, each of which has its own actuator. Since the actuators can be mounted on the base of the structure instead of being carried by motion system of the other axes, they can be relatively large and powerful without …

Evaluation Of Environmental Characteristics Of Wtp Residuals For Disposal In Monofills, Ping Tian

Dissertations

Disposal of water treatment plant (WTP) have raised great concerns due to the stringent water quality standards and environmental regulations, and limited availability of land for ultimate disposal. The ultimate disposal of water treatment plant residuals by using monofill may be one of the most economical, and feasible options. Design and operation of such a monofill will be simple because of the uniformity of the characteristics of WTP residuals.

The objectives of this project were to determine the environmental characteristics of WTP residuals and to apply these characteristics for the design of monofills and development of the metal leaching model …

Counterpulsation Cardiac Assist Device Controller Defection Filter Simulation And Canine Experiments, Carl Edward Werner

Dissertations

Electronic control systems for counterpulsation Cardiac Assist Devices (CADs) are an essential part of cardiac assistance. Synchronization of the counterpulsation CAD controller with the cardiac cycle is critical to the efficacy of the CAD. The robustness of counterpulsation CAD controllers varies with the ability of the CAD controller to properly trigger on aortic pressure (Pa) and electrocardiogram (ECG) signals for sinusoid rhythms, non-sinusoid rhythms and non-ideal signals resulting from surgical intervention. An analog-to-digital converter and digital-to-analog converter based CAD controller development platform was devised on a 33Mhz PC-AT.

Counterpulsation Pa systolic rise and dicrotic notch detectors were demonstrated with a …

Oxidized Sterols In Patients With Diabetic Heart Disease And Microwave-Mediated Stereoselective Synthesis Of 3-Keto Cholesterol And Cholesterol Epoxide, Cholesteryl Ester Epoxides, Meenakashi N. Kothavale

Theses

Oxidized low density lipoproteins (ox-LDL) may play important role in mediating hypercholesterolemic endothelial dysfunction. The uptake of modified LDL by macrophages to form foam cells has been implicated in the enhancement of atherosclerosis. Recent reports have suggested that when LDL undergoes oxidation in vitro , it is accompanied by a substantial loss of free and esterified cholesterol leading to the formation of oxidation products of cholesterol ( oxysterols). These compounds are present in human atherosclerotic plaques and in human foam cells.

In this regard we have recently studied the plasma sterol composition in diabetic heart patients We have found cholesterol …

Three-Dimensional Stress Analysis Of The Femur With Prosthetic Hip Stem Utilizing Computed Tomography Scans Of The Femur For Geometry And Material Properties, Thomas J. Lavin

Theses

Three-dimensional finite element stress analyses of the femur with prosthesis hip stem were performed for two cases, one male and one female, using ideally bonded cemented titanium prostheses. Computed tomography data files were used to derive the three-dimensional femur geometry and material properties for each cortical bone element. The maximum shear stress (4.7 MPa) in the cement was greater then the maximum tensile stress and occurred at the cement-bone interface. The tensile stresses in the cement were less then the fatigue strength of the cement. The stress patterns were quite similar for the two cases.

A data analysis program was …

Optimization Of Ion-Exchange Chromotography With Multiple Gradient Inputs For Protein Separations, Tariq Mahmood

Theses

Gradient elution chromatography is an efficient technique for adjusting the retention of sample components during liquid chromatographic separations. However, the optimization of gradient elution is usually done by trial and error. Thus, for large scale processes this results in expensive and time consuming design and operations. Peak resolution that describes the degree of separation is a commonly used parameter for chromatographic processes. However, in processes where operating time and product dilution are of great importance, resolution alone is not adequate for describing the separation efficiency.

A new parameter "resolution optimization factor" is used for the optimization of gradient elution processes. …

Safety Guidelines For Occupational Hazards To The Reproductive System, Laverne Raquel Ogieste

Theses

Most workers are unaware of the hazards to the reproductive system that surround them in the workplace, and therefore, few if any precautions are taken to avoid unnecessary exposures. In this research, safety guidelines were developed in order to eliminate such dangers from occurring or reoccurring.

These guidelines were developed by reviewing case studies of occupational hazards to the reproductive system, including federal laws and regulations related to safety within the workplace. The following forms were also developed in order to formulate suitable safety guidelines for occupational hazards to the reproductive system. They are: an occupational reproductive survey, a reproductive …

Microporous Silicon Dioxide/Vycor Membranes For Gas Separation, Justin R. Barone

Theses

This study focused on producing membranes for molecular sieving of gases by reducing the pore size of an already existing membrane structure. To do this, SiO₂ was deposited inside the pores of a Vycor tube with initial pore diameter of 4 nm. The film deposition took place by a low pressure chemical vapor deposition (LPCVD) process where diethylsilane (DES) and nitrous oxide (N₂O) were used as precursor gases. A counterflow reactant geometry was used where the precursor gases were flowed on both sides of the porous membrane. This deposition geometry gave higher selectivities and better mechanical stability. …

Oxidative Response Of Immobilized Bovine Blood To The Model Pollutant Phenol, Michael George Nickey

Theses

The primary purpose of this work is to determine if bovine blood can be studied in an immobilized cell bioreactor to determine if a phenol induced oxygen releasing optimum exists. This method of study has the potential to be used to determine what effects xenobiotics have on the oxidative activities of blood.

Three blood fractions containing approximately 21, 44, and 70% red blood cells (RBCs) were immobilized and placed in a recirculating bioreactor. These fractions were exposed injections of 0 ml, 3 ml, or 10 ml amounts of 2000 ppm phenol. The most active fraction was the 21% red cell …
