Refinement Of Innovative Watermelon Grafting Methods With Appropriate Choice Of Developmental Stage, Rootstock Type, And Root Treatment To Increase Grafting Success, Frederic Memmott May 2010

Refinement Of Innovative Watermelon Grafting Methods With Appropriate Choice Of Developmental Stage, Rootstock Type, And Root Treatment To Increase Grafting Success, Frederic Memmott

All Theses

ABSTRACT
Watermelon grafting methods used in Europe and Asia vary, but are based on efficiency, skill and needs. China mainly practices the whole insertion grafting method, whereas, Europe and Japan employ the one cotyledon (splice/slant–cut) grafting method. These methods are not suitable for grafting production in the U.S. due to the labor intensive and high labor cost necessary to successfully produce grafted transplants. This thesis introduced a modified grafting technique called the “Cotyledon Devoid Method” and in three experiments determined; 1) the rootstock leaf number stage (RLNS) at which the greatest grafting success is achieved; 2) the relationship between total …

The Effects Of Aerobic Exercise On Embryonic And Fetal Development In The Pregnant Mare, Jason Anton May 2010

The Effects Of Aerobic Exercise On Embryonic And Fetal Development In The Pregnant Mare, Jason Anton

All Theses

Horses are natural athletes and are commonly competed during early pregnancy. Because horses have singleton pregnancies and are conditioned to human interaction, they may prove to be a useful model in lending greater understanding of the numerous etiologies of intra-uterine growth restriction that is found in women and other mammals. Currently, there has been little research conducted to determine the effects that stress, in the form of aerobic exercise, has on early embryonic and fetal development in the horse. More research is needed to further understand the effects that stress has on early conceptus development in the mare.

Creating A Biomedical Ontology Indexed Search Engine To Improve The Semantic Relevance Of Retreived Medical Text, William Taylor Ii May 2010

Creating A Biomedical Ontology Indexed Search Engine To Improve The Semantic Relevance Of Retreived Medical Text, William Taylor Ii

All Dissertations

Medical Subject Headings (MeSH) is a controlled vocabulary used by the National Library of Medicine to index medical articles, abstracts, and journals contained within the MEDLINE database. Although MeSH imposes uniformity and consistency in the indexing process, it has been proven that using MeSH indices only result in a small increase in precision over free-text indexing. Moreover, studies have shown that the use of controlled vocabularies in the indexing process is not an effective method to increase semantic relevance in information retrieval.
To address the need for semantic relevance, we present an ontology-based information retrieval system for the MEDLINE collection …

An Assessment Of Linear Wrist Motion During The Taking Of A Bite Of Food, Meredith Drennan May 2010

An Assessment Of Linear Wrist Motion During The Taking Of A Bite Of Food, Meredith Drennan

All Theses

Motivated by the goal of building a device capable of detecting when a user takes a bite of food, we examine whether there is a correlation between linear wrist motion and bite detection. Such a device could be used to manage weight loss by tracking eating trends over time and providing real time feedback to the user regarding eating rate or total consumption. A comprehensive analysis of tracking linear motion using low cost inertial sensors is presented. Based on this theory, we discuss the design and tracking accuracy of a prototype bite counting device. We show that tracking position using …

Modified Method For The Microbial Enumeration Of High Fat Foods, Robert Valerio May 2010

Modified Method For The Microbial Enumeration Of High Fat Foods, Robert Valerio

All Theses

Foods of high fat content, such as peanut butter and ground beef, can be of particular interest to food microbiologists due to their role in harboring microorganisms that lead to spoilage and/or foodborne illnesses. In previous studies on raw poultry rendering materials, Glenn (2006) determined standard phosphate buffer serial dilutions produced erratic microbial enumeration results. As the material contained high fat, it was
hypothesized that the immiscibility of fat in the aqueous buffer caused the errors. This could occur by fat globules entrapping microorganisms in foods. Upon serial dilution with aqueous buffers, the fat globules may not be evenly dispersed …

Conservation Biology Of The Diamondback Terrapin In North America, Amanda Hackney May 2010

Conservation Biology Of The Diamondback Terrapin In North America, Amanda Hackney

All Theses

Reptiles are experiencing global declines and pond turtles (Emydidae) are particularly vulnerable. The diamondback terrapin uses multiple habitats to fulfill its life history requirements, in the estuarine environments of the Gulf Coast and Atlantic states (US). Interacting effects of coastal development, overharvesting, abandoned crabbing gear, road mortality, climate change, and nest predation are likely causing population declines throughout its distribution. Protection levels were assessed by referencing each state's Wildlife Action Plan for the species' Conservation Status Ranking Code. At least 7 federal laws directly or indirectly regulate take, wetland, and/or coastal activities (Lacey Act, CWA, FWCA, NAWCA, WPFPA, CBRA, NEPA). …

Sex Ratio Of Embryos From Hyperstimluated Beef Cows, Sterling Davis May 2010

Sex Ratio Of Embryos From Hyperstimluated Beef Cows, Sterling Davis

All Theses

Sex selection is economically and genetically advantageous in cattle production. The only commercially available reliable sex selection technique is sexed semen; however, the technology is expensive and inefficient. Maternal manipulation could be beneficial to sway sex ratio. Frequent ultrasound coupled with rectal palpation has been shown to sway sex ratio towards female. In the preliminary study, cows with a corpus luteum (CL) ≥ 18 mm were randomly assigned to Treatment or Control (n=4 / group). Follicles > 5 mm were destroyed using ultrasound-guided ablation, a CIDR was inserted, and PGF2α (25 mg IM) was administered. Ovarian hyperstimulation began 48 h post-ablation …

Forced Exercise Influences Embryo Quality And Blood Perfusion Of The Dominant Follicle In Mares, Rachael Smith May 2010

Forced Exercise Influences Embryo Quality And Blood Perfusion Of The Dominant Follicle In Mares, Rachael Smith

All Theses

Athletic mares are commonly utilized in an embryo transfer regimen during the breeding season, which allows owners to continue to train and compete with these animals. Evidence suggests exercising mares in a hot and humid environment detrimental to embryo recovery rates. However, the effects of exercise under milder temperatures and its influence on mare reproduction have not been thoroughly examined. Our goal was to compare embryo recovery rates and embryo quality scores of mares under mild environmental conditions of two differing exercise regimens versus a single Control group. Color Doppler ultrasonography was used to capture images of the blood flow …

Mobility Of Plutonium In Zea Mays (Corn): Determination Of Transport Velocities, Spatial Distribution And Correlations With Iron., Shannon Thompson

All Dissertations

Understanding the environmental behavior of plutonium (Pu) is essential for proper radioactive waste disposal or for remedial activities following an accidental release of Pu. The environmental behavior of Pu is influenced by physical, chemical, and biotic factors, such as the simultaneous existence of multiple Pu species, redox transformations at mineral surfaces, colloid formation, and the potential of microbes and plants to affect its sorption to soil. Plant Pu studies have been conducted for quantifying bioaccumulation or phytoremediation. Until now, experimental studies have not focused on the capacity of plants to affect the transport behavior and distribution of Pu in the …

Two Novel Approaches Used To Produce Biodiesel From Low-Cost Feedstocks, Xiaohu Fan, Xi Wang, Feng Chen

Publications

The price of feedstock is one of the most significant factors affecting the economic viability of biodiesel manufacturer. Many approaches were investigated to reduce the biodiesel production cost. The present work gave a preliminary study of two approaches to economically produce biodiesel from waste cooking oil (WCO) and flaked cottonseed. One was the use of ultrasound-assisted synthesis of biodiesel from WCO. The other was the application of in situ transesterification from flaked cottonseed. Gas chromatography (GC) and High performance liquid chromatography (HPLC) results demonstrated the feasibility of using both approaches to produce biodiesel from low-cost feedstock.

Unrooted Stem Cutting Physiology; Water Use And Leaf Gas Exchange Of Severed Stem Cuttings, Peter Alem Jan 2010

Unrooted Stem Cutting Physiology; Water Use And Leaf Gas Exchange Of Severed Stem Cuttings, Peter Alem

All Theses

Stem cuttings are one of the most frequently used and successful methods of vegetative plant propagation. The understanding of unrooted cutting physiology, especially gas exchange and water flux, is crucial for successful propagation of healthy plants. Prior to root initiation, water uptake is limited and leafy stem cuttings are most vulnerable to wilting.
Experiments were carried out in the greenhouse with poinsettia cuttings to determine water uptake, photosynthesis, transpiration and stomatal conductance from the time of severing to rooting, including time spent in storage. Water uptake through the severed stem was investigated in the laboratory and growth chamber. Cutting gas …
