Bovine Follicular Dynamics, Oocyte Recovery,And Development Of Oocytes Microinjected With A Green Fluorescent Protein Construct, M S. Chauhan, S Nadir, T L. Bailey, A W. Pryor, S P. Butler, D R. Notter, William H. Velander, F C. Gwazdauskas

Papers in Biotechnology

The present study was carried out to 1) evaluate the viability of in vitro fertilized zygotes after microinjection of DNA, 2) assess the influence of oocyte quality upon the development rate of embryos when injected with DNA, and 3) determine the integration frequency of green fluorescent protein DNA into microinjected embryos. Oocytes were aspirated from ovaries of nine nonlactating Holsteins and were categorized into grades A, B, C, and D. At 16 h after in vitro fertilization, approximately half of the pronuclear stage presumptive zygotes were classified as having 1 pronucleus or 2 pronuclei, and they were microinjected with DNA …

Pre-Implantation Immunosuppression In The Pregnant Rat:A Possible Role Of Seminal Fluid, Omar A. Habbal, John M. Mclean

Sultan Qaboos University Medical Journal

Successful reproduction involves exposure of the female in significant antigenic challenge. These experiments were done to test the possibility/hypothesis that seminal fluid has an immunosuppressive role in the early stages cf pregnancy,which cculd pretect the conceptus from immonological attack. A highly inbred strain cf rat AO(RTI“) was used in this study. Eleven groups of animals were examined, one during the estrous phase of the ovarian cycle to provide base-line data, five during pseudopregnancy, designated as controls, and five groups during syngeneic pregnancy. Each group contained a minimum of six animals. For each animal, body weight and organ/tissue weightsocf the uterus, …

Preliminary Ecological Risk Assessment To Assess The Implications Of Replacing Chromium Plating With Tantalum Coating, Erik Jonathan Weiss

Theses

An ecological risk assessment process requires a modeling tool that can adapt to changing environmental conditions. Computer simulation tools are a useful means to develop an ecological risk assessment, because if properly used they can provide an organized framework to evaluate multiple data sources, complex problems and hypotheses. An evaluation was completed of the University of Tennessee CHEMS-1 model that ranks and scores contaminant toxicity and exposure potential. Tantalum posed less of a hazard than hexavalent chromium to the terrestrial and aquatic animals. Although, results indicated that the vanadium compounds, in particular vanadium pentoxide, presented the greatest hazard, with hexavalent …

A Field Study Coupling Soil Fractionation And Sonic Energy For Enhancing The In Situ Removal Of Volatile Organic Compounds In The Vadose Zone, Hassan Kaleem

Theses

Remediation of sites contaminated with hazardous wastes could be an expensive endeavor. There is, therefore, the need to explore techniques, which can reduce the remediation time and achieve regulatory specifications, thus reducing the cost involved in a site remediation exercise.

In this work, we investigated the use of sonic energy to enhance the in situ removal rate of trichloroethylene and dichloroethylene from a site in Hillsborough Township. New Jersey. The experiments were performed with and without sonic energy and each time the concentration of the trichloroethylene swept out from the site and the flowrate of the effluent gas were measured. …

Characterization Of Tantalum Coatings On Steel Substrates, Prabha Shivaramkrishnan

Theses

Sputtered tantalum can be used as an effective corrosion resistant barrier if the coating is continuous, free from defects and is adherent to the substrate it is intended to protect. For corrosion-applications 100% bcc phase tantalum is preferred. X-ray diffraction results indicate that sputtered tantalum deposits typically contain a mixture of bcc and beta phases. Depending on the deposition conditions the morphology of tantalum coatings as studied using scanning electron microscopes can vary from irregular, dendritic structure to a defined step type structure. A "cauliflower type" structure has also been observed. Extended x-ray absorption fine structure measurement was used to …

An Investigation Of The Effect Of Sonic Frequency In The Removal Of Volatile Organic Compounds From Soils Using A Siren-Pneumatic Fracturing Coupled Technique, Chin-Yu Lin

Theses

This study investigates the effect of frequency from sonic energy coupled with soil fracturing for the removal of volatile organic compounds from low permeability soils. The laboratory experiments consisted of a test cell, 12 1/2 inches by 12 1/2 inches and 23 3/4 inches high, containing a 1/2 inch geotextile made to simulate the fracture. The pneumatic sound generator used was a siren type generator designed and built at NJIT.

Laboratory experiments were performed using the NJJT siren at frequencies of 2957, 6637, 10317, 13997 Hertz and baseline tests with no sound energy were also conducted. The free moisture …

Model And Clinical Device Development For Noninvasive Diagnosis Of Low Back Pain And Dysfunction, Ravi Patraju

Theses

Millions of people suffer from acute or chronic low back pain. In order for proper treatment to be administered, a patient must receive an accurate diagnosis. Therefore, it is critical to develop an objective model to measure the motion and any dysfunction of a patient's low back. Only then can a physician effectively implement the correct therapy and measure its effectiveness through follow-up to minimize or eliminate low back pain.

Numerous cadaveric, active and passive studies have been done to understand the mechanics of low back disorders. However, only living human subjects suffer from low back pain and therefore cadaveric …

A Comparative Study Of Sequence Analysis Tools In Computational Biology, Wei-Jen Chuang

Theses

A biomolecular object, such as a deoxyribonucleic acid (DNA), a ribonucleic acid (RNA) or a protein molecule, is made up of a long chain of subunits. A protein is represented as a sequence made from 20 different amino acids, each represented as a letter. There are a vast number of ways in which similar structural domains can be generated in proteins by different amino acid sequences. By contrast, the structure of DNA, made up of only four different nucleotide building blocks that occur in two pairs, is relatively simple, regular, and predictable.

Biomolecular sequence alignment/string search is the most important …

Metrics For Estimating The Product Disassembly Effort, Pradeep Kumar Yedlarajaiah

Theses

The concepts of environmentally friendly manufacturing and ecological reuse of materials have resulted in an increase in the number of disposed products that are disassembled. Moreover, the imposition of EPA regulations is forcing companies to invest in methods for protecting the environrnent. The first strategy in this vein is material recycling. The issue of recycling became important because of the limited landfill space, diminishing natural resources, environmental pollution due to dumping of products containing hazardous materials. Likewise, it is projected that the cost of extracting materials from natural resources is going to be much more expensive when compared to reclaiming …
