Emulsified Chitosan-plga Scaffolds for Tissue Engineering
(Oklahoma State University, 2005-12-01)
This study evaluated the formation of chitosan-50:50 poly-lactic-co-glycolic acid (PLGA) blend matrices using controlled rate freezing and lyophilization technique. An emulsion system was used in the presence of ...
Modulation of AMPA receptor desensitization by nootropic drugs and endogenous proteins
(2005-05)
AMPA receptors play a central role in basal excitatory synaptic transmission as well as synaptic maturation and plasticity. An important characteristic of AMPA receptors (AMPARs) is the rapid and profound desensitization ...
Exploring the Problem of Ambiguity in Context-free Grammars
(Oklahoma State University, 2005-07-01)
The general problem of ambiguity detection is unsolvable. Some context-free languages are inherently ambiguous. There is no algorithm that can detect the ambiguity of context-free grammars (CFG) in general since it is a ...
Model Selection for Value-at-risk: Univariate and Multivariate Approaches
(Oklahoma State University, 2005-12-01)
This thesis sought to determine the best among various models in estimating VaR. Models were evaluated in terms of both accurate probabilities of extreme events and lack of correlation among exceptions. In DJIA index ...
Web accessibility for students with disabilities who use assistive technology: A moving target for postsecondary institutions
(2005-07)
Scope and Method of Study: The purpose of this study was to determine what colleges and universities are doing to help students with disabilities who use assistive technology access asynchronous web-based courses. Participants ...
Expression of Spatial Variability in Corn (Zea Mays L.) as Influenced by Growth Stage Using Optical Sensor Measurements
(Oklahoma State University, 2005-05-01)
The time at which remote sensing technology can quantify differences in corn plants should be the time at which the CV of the measured data is the highest. At that growth stage, the corn produces the greatest amount of ...
Development of a technology transfer program for small manufacturers in a competitive environment
(2005-07)
Scope and Method of Study: The purpose of this study was to determine the desirable technology transfer dimensions, attributes, approaches, programs, and processes and the desirable organizational structure which could be ...
Role of coronatine in the virulence of Pseudomonas syringae pv. tomato DC3000 on edible brassicas
(2005-12)
Scope and Method of Study: The phytotoxin coronatine (COR), produced by different strains of Pseudomonas syringae has two moieties: coronamic acid (CMA) and coronafacic acid (CFA). The bacterium P. syringae pv. tomato ...
Evaluating methods for improving nitrogen use efficiency in corn and hard red winter wheat
(2005-05)
Scope and Method of Study: For chapter one, Corn (Zea mays L.) experiments were conducted to evaluate spectral reflectance, measuring the normalized difference vegetation index (NDVI) with a GreenSeeker Hand Held optical ...
Influence of Patch-burn Management on the Nesting Ecology of Grassland Birds at the Tallgrass Prairie Preserve, Oklahoma
(Oklahoma State University, 2005-07-01)
Fire and Grazing were the driving forces shaping the tallgrass prairie before European settlers inhabited the Great Plains. Areas that had not recently burned were more likely to burn due to an increase in litter cover, ...
