The abundance and distribution of fishes in the cooling-water canal system of an electric generating station : with emphasis on the effect of cooling towers
(Texas A&M University. Libraries, 1978)Trawl collections were taken from June 1974 to September 1975 to determine the abundance and distribution of fishes in the canal system of the Houston Lighting & Power P.H. Robinson Generating Station with emphasis on ... -
Airport area planning and implementation : a review and analysis
(Texas A&M University. Libraries, 1980)Planning for the secondary impacts of airport development is a complex process which requires the involvement of agencies at all levels of government as well as private individuals. This dissertation evaluates the effectiveness ... -
The American oyster (Crassostrea virginica) as a bioindicator of trace organic contamination
(Texas A&M University. Libraries, 1993)This study was designed to examine the uptake and depuration of trace organic contaminants, e.g. poly nuclear aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), including planar congeners, and butyltin species, ... -
Biochemically significant reactions of arsenic compounds
(Texas A&M University. Libraries, 1982) -
Biodegradation of Kuwait crude oil in the presence and absence of the dispersant Corexit 9527
(Texas A&M University. Libraries, 1986)Kuwait crude oil was subjected to a time series, laboratory simulation of biodegradation by incubation in nutrient enhanced seawater with a mixed culture of oil degrading microorganisms isolated from the Gulf of Mexico. ... -
Circulation and temperature effects on the development and distribution of the eggs and larvae of the Antarctic krill, Euphausia superba : a modeling study
(Texas A&M University. Libraries, 1989)An existing three-dimensional time-dependent circulation model was adapted to investigate the circulation in the South Shetland Islands - Bransfield Strait region. The simulated circulation distributions show seasonal ... -
The compilation of diagrammatic transects and their application to preliminary environmental assessment of water resources development in Texas
(Texas A&M University. Libraries, 1976)Water resources development in Texas is primarily of two types, channelization and surface impoundments. Effects of these types of projects are discussed in terms of environmental effects in Texas. With this background, ... -
The continuum regime charging of submicrometer particles by bipolar air ions : theory and experiment
(Texas A&M University. Libraries, 1982)A study was undertaken to characterize experimentally the continuum regime charging of aerosols by bipolar gaseous ions and to evaluate theoretical models for the charging process. Experiments were conducted on monodisperse ... -
Determination of the erodibility factor of soils and lignite spoils
(Texas A&M University. Libraries, 1981)Surface strip mining is currently the fastest way to recover lignite and bituminous coal. The strip mining results in the disturbance of large acreages of land. However, specific management of the spoils is required to ... -
Determining dispersion parameters to predict ground-water contamination
(Texas A&M University. Libraries, 1983)Use of contaminant transport models to predict the potential for ground-water pollution at waste disposal sites has been hindered by lack of methods to determine dispersion parameters. As an aid to overcome this difficulty, ... -
Disturbance in a stressed environment : bank vegetation of the Gulf Intercoastal Waterway at Cedar Lake, Texas
(Texas A&M University. Libraries, 1977)The effect of disturbance on vegetation in a variably stressed environment is examined in seven sites along the Gulf Intracoastal Waterway in Brazoria County, Texas. The relationship of spoil deposition to vegetation is ... -
The effects of certain physical and biological factors on the survival and the hatching rates of Psorophora columbiae (Dyar and Knab) (Diptera: Culicidae) eggs
(Texas A&M University. Libraries, 1989)The results of laboratory tests indicated diapausing Psorophora columbiae eggs were more tolerant to the low temperatures used (8° to -6°C) than were non-diapausing eggs, particularly at temperatures equal to and below ... -
The effects of drilling fluids (muds) and turbidity on the metabolic state of the coral Acropora cervicornis : calcification rate and protein concentration
(Texas A&M University. Libraries, 1983)The effects of ten used drilling muds on coral health have been examined by monitoring changes in calcification rate and soluble tissue protein in the coral Acropora cervicornis. Exposure to 25-ppm (v/v) of one mud for 24 ... -
Effects of evaporative salt water cooling towers on salt spray and salt deposition on surrounding soils
(Texas A&M University. Libraries, 1978)Five salt water cooling towers recently constructed near Galveston Bay, Texas have been shown to contribute to salt deposition in the surrounding area. Levels as high as 1200 kg salt/ha/yr were encountered within 100 m of ... -
Effects of rainfall, recruitment, and the operation of the Cedar Bayou Electric Generating Station (Baytown, Texas) on the dynamics of fish and macrocrustacean communities in the brackish intake and discharge waters
(Texas A&M University. Libraries, 1982)The impact of the Cedar Bayou Electric Generating Station upon fishes and macrocrustaceans in the intake area, discharge canal, and cooling lake during 1972-1979 was evaluated. Data used to determine relative abundance, ... -
Environmental aspects of suction cutterheads
(Texas A&M University. Libraries, 1983)Maintenance and new work dredging of existing waterways and navigational channels is vital to the Nation's economy. Cutterhead dredges share the major burden of dredging in the United States. The sediments in the waterways ... -
Environmental factors affecting spore germination and early life cycle stages of selected Platycerium desv. species
(Texas A&M University. Libraries, 1982)Platycerium coronarium and P. superbum spores responded to 26(DEGREES)C on a thermogradient with greatest germination percentages. The same temperature was also optimum for gametophytic surface area increase and juvenile ... -
Environmentally induced increases in pain reactivity
(Texas A&M University. Libraries, 1993)Prior research has shown that an aversive event can produce either an increase (hyperalgesia) or a decrease in pain reactivity (hypoalgesia). Researchers have extensively examined both the behavioral and neurobiological ... -
