The ammonia-producing enzymes in tails of white shrimp
(Texas A&M University. Libraries, 1977)Shrimp muscle extracts were assayed for the ammonia-producing enzymes; alanine oxidase, arginine oxidase, glycine oxidase, proline oxidase, serine oxidase, adenase, guanase, urease, arginase, adenosine deaminase, and AMP ... -
Analysis of electrical signatures in synchronous generators characterized by bearing faults
(2009-05-15)Synchronous generators play a vital role in power systems. One of the major mechanical faults in synchronous generators is related to bearings. The popular vibration analysis method has been utilized to detect bearing ... -
Analysis of tests in wells with multiphase flow and wellbore storage distortion
(Texas A&M University. Libraries, 1989)The analysis and interpretation of well test data usually depends on the assumptions of a constant reservoir flowrate and single phase flow in the reservoir. These assumptions are usually not valid for field data. This ... -
Analytical and numerical methods for boundary value problems of mixed type
(Texas A&M University. Libraries, 1990)Existence of a weak solution for some boundary value problems of mixed and hyperbolic types is proved by constructing multipliers which satisfy the multiplier inequalities. The nature of a singularity is then examined by ... -
Analytical Considerations of the Stretched Exponential/Power Law Exponential Relations Used for Time-Rate Decline Curve Analysis
(2017-07-20)Since their introduction to the petroleum literature in 2008/2009, the stretched exponential (SE) and the power-law exponential (PLE) relations have become the "conservative" standard for time-rate (decline curve) analysis ... -
Assessment of Eagle Ford Shale Oil and Gas Resources
(2013-07-30)The Eagle Ford play in south Texas is currently one of the hottest plays in the United States. In 2012, the average Eagle Ford rig count (269 rigs) was 15% of the total US rig count. Assessment of the oil and gas resources ... -
Auditing the Quality of Process Hazard Analysis (PHA) Studies
(2017-07-20)The petrochemical industry is subject to various federal and local regulations and requirements that are challenging to meet and resource-intensive. Time and human factors often lead to a “check box” mentality where ... -
Baseline blood chemistry determinations of wild versus colony born common marmosets (Callithrix jacchus) maintained in an indoor-outdoor environment
(Texas A&M University. Libraries, 1981)The objective of this study was to present reliable and quality controlled reference values for the hematological and serum constituents of the adult normal cotton-eared marmoset, and to note the differences, if any between ... -
Botanical and nutritive content in diets of sheep, Angora goats, Spanish goats, and deer grazing a common pasture
(Texas A&M University. Libraries, 1977)A study was initiated in August 1975 to illuminate the dietary interrelationships among four kinds of small ruminants of the Edwards Plateau of Texas. Interrelationships were based on the botanical and nutritive composition ... -
Californium-252 plasma desorption mass spectrometry of chlorophylls and chlorophyll aggregates
(Texas A&M University. Libraries, 1980)[^252]Cf-plasma desorption mass spectrometry is shown to be an excellent method for the analysis of chlorophylls in aggregated states. Investigation provide experimental evidence for the view that chlorophylls can be ... -
A causal analysis of juvenile hormone accumulation in adult male Hyalophora cecropia (L.) (Lepidoptera, Saturniidae)
(Texas A&M University. Libraries, 1978)Recent investigations on the massive accumulation of juvenile hormones I and II in adult male Hyalophora cecropia have revealed that the corpora allata (CA) are not secreting juvenile hormones (JH) but JH acids and that ... -
²⁵²Cf-plasma desorption mass spectrometry of chemically protected ribo- and deoxyribooligonucleotides
(Texas A&M University. Libraries, 1980)A new method of determining the base sequence, the purity and the molecular weight of a chemically protected ribo- or deoxyribooligonucleotide is described. Using the method ²⁵²Cf-plasma desorption mass spectrometry positive ... -
Changes occuring in yeasted wheat flour doughs during cryogenic freezing and frozen storage
(Texas A&M University. Libraries, 1987)During this study, an apparatus was designed and constructed to allow for cryogenic freezing of 10 gram loaves of yeasted wheat flour dough. Dough loaves were frozen by direct contact freezing with boiling Freon compounds. ... -
The characterization and catalytic activity of molybdenum-Y zeolites
(Texas A&M University. Libraries, 1982)The characterization of several molybdenum zeolites was facilitated using X-ray photoelectron spectroscopy. Samples prepared from the reaction of Mo(CO)(,6) with ultrastable zeolites exhibited superficially high concentrations ... -
Characterization of polymerizable surfactant vesicles by nuclear magnetic, absorbance and fluorescence spectroscopy
(Texas A&M University. Libraries, 1982)The formation of vesicles and polymeric vesicles from unsaturated surfactants was discussed in regards to conditions for formation (sample size and sonication time), polymerization, substrate entrapment, hydroxide ion ... -
A characterization of the lipids of the organisms which make up the main bulk of a coral reef with particular emphasis on the hydrocarbons
(Texas A&M University. Libraries, 1965)The lipid extracts of a series of living and fossil reef organisms were subjected to analysis by a variety of techniques. Initial column chromatography over silicic acid gave a series of fractions: 1. Saturated and monenoic ... -
Chemical and functional properties of glandless cottonseed protein
(Texas A&M University. Libraries, 1989)Glandless cottonseed protein isolates (CPI-I and II) were prepared using gel filtration chromatography. They contained large amounts of glutamic acid, arginine, and aspartic acid and had minimum solubilities at pH 4 and ... -
Circulating Fluidized Bed Boiler Model for Predicting Emission Levels of Tire Fuel using Base Case of Lignite Fuel
