Environmental Air Pollution Analysis In Selected Areas Of Abu Dhabi Emirate, Mahfoodh Abdulla Mohammed Darbool

Theses

There are little data available for environmental pollution, as well as air pollution and statistical information published in the United Arab Emirates. Especially, Abu Dhabi Emirate, has been the location of the UAE's most persistent and extreme levels of industrial oil waste and chemical smog and air pollutants which produces sulphur dioxide emission. In addition, has a high vehicle population, which produces carbon monoxide emission from the motor vehicle exhaust. The acute toxicity of carbon monoxide (CO) has long been recognized and well documented. The motor vehicle is by far the largest contributor to Co accounting for 55% of total …

The Effects Of Chromated Copper-Arsenate (Cca) Pressure-Treated Wood On Local Sediments And Benthos In A Freshwater Lake, William A. Romeo

Theses

This study looked at the sediment and benthic organism effects of exposure to a Chromated Copper-Arsenate (CCA) treated wood bulkhead in a lake environment with respect to 1) the leaching and accumulation of chromium, copper and arsenic in the nearby sediments, 2) accumulation of these metals in local benthic organisms and 3) the effects of these metals on the local benthic community structure. Sediment samples, taken at regular distances away from a CCA bulkhead and three reference areas in a freshwater lake in Wayne, NJ, were sieved to remove the fine particle fraction (<70µm) which was then analyzed for the metals of concern. Benthic organisms were sampled at the same locations, enumerated, identified, dried and also analyzed for the metals in question. Analysis of sediment metal concentrations revealed high levels of copper at all sampling locations. This was attributed to the annual addition and accumulation Of CuS0₄ added to the lake. There …

Evaluating Bighorn Habitat: A Landscape Approach, William C. Dunn

United States Bureau of Land Management: Staff Publications

This technical note describes a method that incorporates a landscape approach with the use of Geographic Information Systems (GIs) to measure habitat and impacts for Rocky Mountain and desert bighorn sheep and to rank potential transplant sites. A landscape approach, in which habitat is viewed from a large-scale perspective as an assemblage of patches, is used because: (1) bighorn habitat is naturally patchy due to the affinity of bighorn for terrain that is both open and mountainous; (2) fragmentation (i.e., increased patchiness) often is the most severe consequence of human disturbance; and (3) the proximity and distribution of neighboring bighorn …

Windbreaks For Snow Management, James R. Brandle, H. Doak Nickerson

School of Natural Resources: Faculty Publications

In areas of high winds and blowing snow, windbreaks can reduce the amount of effort spent on snow management. They can be designed to spread snow across a large area or to confine it to a relatively small storage area. The design of your windbreak will depend on your objective. Field windbreaks designed to distribute snow evenly across a field should be tall and porous. In contrast, windbreaks designed to capture snow and control drifting should have multiple rows with high density. There is no one set design, number of rows, or width of planting that is ideal for every …

John U. Lloyd Beach State Recreation Area Nature Guide, Nsu Oceanographic Center

Technical Reports

John U. Lloyd State Park is a 251 acre recreation area located on Ocean Drive in Dania, Broward County, Florida. The park is adjacent to Port Everglades and has a beach front park spanning 2.5 miles. It preserves some of south Florida's vanishing natural resources, while at the same time offers the public usage of beach and water recreational activities. Surf fishing, picknicking, and canoeing along the tidal waterway New River Sound or Whiskey Creek are just some of the activities the public can enjoy.

The recreation area was named in memory of the late John U. Lloyd, Broward County's …

Track Structure And Radiation Transport Model For Space Radiobiology Studies, F. A. Cucinotta, J. W. Wilson, Robert Katz, W. Atwell, G. D. Badhwar, M. R. Shavers

Robert Katz Publications

Radiobiology experiments performed in space are deemed necessary for validation of risk-assessment methods. The understanding of space radiobiology experiments must combine knowledge of the space radiation environment, radiation transport, and models of biological response. The heavy ion transport code HZETRN has recently been combined with improved models of the galactic cosmic rays (GCR) and extensive comparisons made to measurements on the space shuttle with a tissue equivalent, proportional counter. HZETRN was also coupled with track-structure models of biological damage from heavy ions. Track-structure calculations using improved models of the radial dose distribution around the path of heavy ions provide a …

Factors Affecting Interannual Movements Of Snowy Plovers, Peter W. C. Paton, Thomas C. Edwards Jr.

Natural Resources Science Faculty Publications

We studied the interannual movements of 361 individually color-banded adult Snowy Plovers (Charadrius alexandrinus nivosus) at Great Salt Lake, Utah from 1990 to 1993. In northern Utah, Snowy Plovers nested in a dynamic environment; suitable breeding habitat declined by 50% at two study areas in four years. Male Snowy Plovers were more site faithful than females; 40% of males exhibited fidelity compared with 26% of females (P < 0.01). However, as the amount of available suitable nesting habitat declined, male site fidelity diminished, whereas female fidelity remained relatively constant. We found strong evidence that female site fidelity was affected by nesting success in the previous year. Females that nested unsuccessfully were less likely than successful females to exhibit site fidelity the following year; males did not exhibit this nest-success bias. In addition, unsuccessful females breeding at sites with high densities of nests tended to disperse the following year, whereas male site fidelity did not appear to be affected by either a study site's overall nesting success the previous year or a study site's nest density the previous year. Female avoidance of areas with high densities of nests may be an antipredator strategy. Snowy Plovers in northern Utah have biparental incubation duties, but only males care for broods. Familiarity with brood-rearing areas was one plausible explanation for male-biased fidelity. However, we could not eliminate an alternative hypothesis that both focal study sites represented scarce breeding areas due to the presence of freshwater, and male Snowy Plovers preferred to use the same areas rather than disperse. We propose that more landscape-level studies are needed to address questions concerning local and regional movement patterns.

Space-Based Genetic Cryoconservation Of Endangered Species, Michael Noah Mautner

Chemistry Publications

Genetic materials of endangered species must be maintained, for cryoconservation, permanently near liquid nitrogen temperatures below 77 K. Due to the instability of human institutions, permanent safety is best provided at storage sites that maintain passively the needed low temperatures, and provide barriers to access. The required conditions are available in permanently shaded polar lunar craters with equilibrium temperatures of 8 to 40 K, on the moons of Saturn, and unshielded storage satellites. A genetic depository can be incorporated readily into planned lunar programmes.
