Effects Of Sperm Preparation On In Vitro Fertilization In Pig, Mongkol Techakumphu, Wichai Tantasuparak

The Thai Journal of Veterinary Medicine

The aim of these experiments was to investigate the effects of sperm preparation on the success rate of in vitro fertilization in the pig. Three factors, the time period for capacitation, the type of sperm and the sperm motility-stimulating factors were studied by investigating their effect on the cleavage of pig follicular oocytes, after IVM-IVF-IVC. A total of 1,235 immature oocytes, collected from 3 to 6 mm follicles of gilt ovaries gathered at slaughterhouse were allocated to 3 experiments. Immature oocytes were cultivated in TCM199 NaHCO3 supplemented with 10 μg/ml of FSH/LH and 1 μg/ml of Estradiol-17ẞ for 44 hrs. …

Opening Doors: Culture Learning And Conversational Narratives With First Generation Hmong Refugee Women, Lucy Vincent Kimbro Jun 1997

Opening Doors: Culture Learning And Conversational Narratives With First Generation Hmong Refugee Women, Lucy Vincent Kimbro

Dissertations and Theses

The life experiences of two first generation Hmong refugee women form the basis of this study. Through loosely structured but guided interviews, memories of their lives in Laos and in refugee camps in Thailand, as well as their perspectives, feelings, and opinions about current aspects of their lives, the effects of American culture on their family; and their engagement in the language and culture learning process are explored.

An examination of the involvement of Hmong women in research and ethnographic accounts concerning Hmong culture, history, and experience, show that Hmong women's perspectives have often been overlooked or disregarded. One purpose …


Multi-Wavelength Pyrometric Systems For Emissivity-Independent Non-Contact Temperature Sensing, Michael B. Kaplinsky May 1997

Multi-Wavelength Pyrometric Systems For Emissivity-Independent Non-Contact Temperature Sensing, Michael B. Kaplinsky

Dissertations

A Multi-Wavelength Imaging Pyrometer (M-WIP) for real-time remote sensing of temperature profiles of targets with unknown emissivity was developed and demonstrated. To measure the spectral radiance of a target at several distinct wavelengths an M-WIP system was implemented based on an 320x122-element PtSi IR-CCD imager with an assembly of 7 narrow-band 1k filters in the range from 1790nm to 4536nm. A real-time algorithm for simultaneous estimation of the temperature and model parameters of the target emissivity from the least-squares fit of the theoretical model of 1k camera output signal to the experimental spectral measurements was developed and implemented. This rea1-time …


Motion Compensation And Very Low Bit Rate Video Coding, Shu Lin May 1997

Motion Compensation And Very Low Bit Rate Video Coding, Shu Lin

Dissertations

Recently, many activities of the International Telecommunication Union (ITU) and the International Standard Organization (ISO) are leading to define new standards for very low bit-rate video coding, such as H.263 and MPEG-4 after successful applications of the international standards H.261 and MPEG-1/2 for video coding above 64kbps. However, at very low bit-rate the classic block matching based DCT video coding scheme suffers seriously from blocking artifacts which degrade the quality of reconstructed video frames considerably. To solve this problem, a new technique in which motion compensation is based on dense motion field is presented in this dissertation.

Four efficient new …

Sampling And Analysis Of Trace Level Volatile Organic Compounds From Air Via Membrane Permeation, Naihong Zhu

Dissertations

The objective of this study is to develop air sampling techniques using membrane permeation. Two novel techniques for sampling and analysis of trace level VOCs from air via membrane permeation are presented:

  1. selective concentration of VOCs into a canister using a membrane permeator;
  2. on-line membrane extraction for direct introduction of VOCs from air emissions into a gas chromatograph.

In the membrane permeator-canister sampling system (MPCS), the air sample containing trace level VOCs as well as some interferences such as moisture are passed through the membrane module. Polydimethyl siloxane membrane used in this research is highly permeable to organic compounds, but …

The Fatigue Problems Of Cracks Subjected To Obliquely Incident Stress Waves, I-Chung Weng May 1997

The Fatigue Problems Of Cracks Subjected To Obliquely Incident Stress Waves, I-Chung Weng

Dissertations

Catastrophic failure of aircraft and other structures are often caused by undetected cracks. Fracture mechanics has been developed to augment traditional static and fatigue design. In the static theory of fracture mechanics, extensive treatment has been given to the stress distribution around sharp cracks and notches under various loading conditions. Previous works on the problems of dynamic loadings are not accurate in dealing with singularities at high frequencies. The numerical solutions become unrealistic at high frequencies in many practical applications.

To address the need to obtain the stress intensity factor in high frequency dynamic loading situations, we studied the use …

Development Of Methods For Field Determination Of Chromium (Vi) In Water And Groundwater, David John Chesbro May 1997

Development Of Methods For Field Determination Of Chromium (Vi) In Water And Groundwater, David John Chesbro

Theses

In this study, methods for the determination of chromium (VI) in fresh water at low ppb levels for the use under field conditions were developed. The plan was to devise a simple and inexpensive on-site field method which would be useable by people who are not professional chemists. An investigation was carried out to develop a preconcentration and determination procedure for the analysis of chromium (VI) using anion-exchange membranes and/or resins. The chromium (VI) would be sorbed to the solid support and then treated with 1 ,5-diphenylcarabzide, a specific colorimetric reagent for chromium (VI), which forms a red complex upon …


Decontamination Of Aquifers Via Air Sparging/Biofiltration : An Experimental Study, Armando Mora Tellez May 1997

Decontamination Of Aquifers Via Air Sparging/Biofiltration : An Experimental Study, Armando Mora Tellez

Theses

In this study experiments were performed in order to show feasibility of an integrated air sparging/biofiltration process for cleaning contaminated groundwater. Feasibility was also meant in the sense of meeting regulatory constraints. Using toluene as model compound and changing flowrates for the sparged air, it was shown that despite fluctuations in the toluene concentration at the inlet of the biofilter, the concentrations at the outlet of the unit were essentially constant over long periods of time and remained below the levels dictated by environmental regulations. However an increase in outlet concentrations at levels not meeting regulatory constraints was observed after …


Relative Dentifrice Abrasivity On Dentin And Enamel, Laura Marchetti May 1997

Relative Dentifrice Abrasivity On Dentin And Enamel, Laura Marchetti

Theses

The abrasive characteristics of six (6) brands of toothpastes on Enamel and Dentin material were assessed. Human teeth were sliced to expose the dentin surface and then polished using 3 μm and 0.25 μm diamond paste. The outside surface of the tooth (after slicing) was used "as is" for the enamel surface testing. The surface smoothness was evaluated prior to testing using a surface profiler and averaging four (4) to five (5) readings across the surface for each sample.

The tooth slices were then embedded into the acrylic plate surface by routing out an area with a dental drill and …


Analysis And Modeling Of Ultrasound Enhanced Soil Washing Process, Kamalavathany Rajaratnam May 1997

Analysis And Modeling Of Ultrasound Enhanced Soil Washing Process, Kamalavathany Rajaratnam

Theses

In this research, statistical analysis of data from ultrasound enhanced soil washing process was performed. The process was optimized using a statistical model. The model had four factors namely power, solvent:soil, surfactant, and dwell time as process variables. The percentage of removal efficiency was considered as the dependent variable. The results from two full and one partial factorial designs were analysed. Interactions up to third order were considered in the analysis, but the results from full factorial design showed that those of order higher than second had insignificant contributions to the removal of contaminants. Since the higher order interactions of …


Assessment Of Potential Operating Benefits Incurred By Implementing Iso 14001 : Five Case Studies From The New Jersey Chemical Industry, Stefanie Gitter May 1997

Assessment Of Potential Operating Benefits Incurred By Implementing Iso 14001 : Five Case Studies From The New Jersey Chemical Industry, Stefanie Gitter

Theses

Environmental management is an important aspect of strategic planning and competitiveness for many businesses. Environmental management systems (EMS) are operating policies that are established to help a company measure progress towards goals set forth in a strategic environmental plan. A growing number of EMS models are being used by countries and industry groups, so the International Standards Organization (ISO) developed one model to prevent duplicate efforts which can result when companies try to meet the import requirements of different countries.

The ISO-EMS model is a series of standards, and ISO 14001 is the first to be published. Companies will be …


An Analytical Approach To Toxic Substance Replacement In Support Of Pollution Prevention, Ithan B. Zimmer May 1997

An Analytical Approach To Toxic Substance Replacement In Support Of Pollution Prevention, Ithan B. Zimmer

Theses

In support of pollution prevention and in accordance with Executive Order 12356 concerning pollution prevention, all federal agencies must comply with the Toxic Release Inventory (TRI) chemical release reduction and pollution prevention planning. The inventory lists hundreds of chemicals and choosing those to replace and finding actual replacement chemicals or procedures is not always clear. This study focuses on an analytical approach to this problem by understanding the application of two substances. The representative chemicals are two volatile organic compounds (VOC), ethyl ether and ethanol, used as solvents in ammunition manufacturing.

Thirteen military specifications provide the cases involving ether. Ethanol's …
