Identifying the concepts, principles, and applications of technology needed by entry-level workers in food, environmental, and natural resource systems in 2010
(Texas A&M University, 2000)
The purpose of this study was to revise the competencies that are needed to move the National FFA Agricultural Mechanics career development event (CDE) into the 21st Century. The following objectives were used to guide the ...
Optimizing detector placement for isolated intersections based on minimizing average delay and number of stops
(Texas A&M University, 2000)
Detector layout has a significant effect on the performance of an intersection. Operational performance of an intersection is often measured with delay. Delays experienced in rural areas are not significant due to low ...
Evaluation of peracids for ante mortem disinfection of the chicken upper gastrointestinal tract to reduce food-borne pathogen transmission
(Texas A&M University, 2000)
Paratyphoid Salmonella is an important human food-borne pathogen that commonly contaminates broiler carcasses. Previous studies have implicated upper gastrointestinal contents as a major critical control point during ...
Improving the searching abilities of a real-valued genetic algorithm
(Texas A&M University, 2000)
This investigation shows that a genetic algorithm seems to be able to search a solution space more effectively with the addition of a gradient-based local improvement scheme. The objective of this research was to determine ...
Using pattern recognition in electron density map interpretation
(Texas A&M University, 2000)
The work reported here describes methods for automating the structure determination of proteins from electron density maps. To begin, a summary of crystallography, including the history and methods of collecting diffraction ...
Rotordynamic evaluation of frequency dependent impedances of hole-pattern gas damper seals
(Texas A&M University, 2000)
Two hole-pattern seals are compared with one smooth bore seal. The two hole-pattern seals have cell depths of 2.03 mm and 3.18 mm with a cell diameter of 1.59 mm. The hole area density factor for both hole-pattern seals ...
The characterization of eight tyrosine to phenylalanine mutations in ribonuclease SA3
(Texas A&M University, 2000)
An investigation of the contribution of hydrogen bonding to protein stability was performed using Ribonuclease Sa3 as a model system. Ribonuclease Sa3 (RNase Sa3) has eight tyrosine residues. Eight mutants were constructed ...
Assessment of canine liver function by metabolism of lidocaine to monoethylglycinexylidide: a preclinical study
(Texas A&M University, 2000)
This study reports the evaluation of lidocaine pharmacokinetics and appearance and disappearance of its de-ethylated metabolite, monoethylglycinexylidide (MEGX). The study was completed to develop a new lidocaine-MEGX liver ...
Vegetation, soils, and surface hydrology of playa landforms in the Rio Grande Plains, Texas
(Texas A&M University, 2000)
Playas in the Rio Grande Plains of southern Texas were compared with respect to their: 1) size, shape, soil properties, and microtopography, 2) vegetation composition and structure, 3) surface water accumulation potential, ...
Further experimental studies of steam-propane injection to enhance recovery of Morichal oil
(Texas A&M University, 2000)
In 1998-1999, experimental research was conducted by Goite at Texas A&M University into steam-propane injection to enhance oil recovery from the Morichal field, Venezuela. Goite's results showed that, compared with steam ...
