Effects Of Zebra Mussel, Dreissena Polymorpha, Infestation On Lake Dardanelle Water Quality, Charles J. Gagen, Joseph N. Stoeckel Jun 1995

Effects Of Zebra Mussel, Dreissena Polymorpha, Infestation On Lake Dardanelle Water Quality, Charles J. Gagen, Joseph N. Stoeckel

Arkansas Water Resources Center Technical Reports

Zebra mussels recently invaded southern waterways including the Arkansas River. Exponential population growth and high filtration capacity of dense populations could alter reservoir ecosystem function. Furthermore, they attach to hard surfaces; thus, threatening normal operations of many artificial structures. We designed this study to provide baseline data prior to high population levels of zebra mussels in Lake Dardanelle. The characterization of spatial and temporal variability in water quality, zooplankton, phytoplankton, and macrophytes will allow testing of several hypotheses. We sampled zebra mussel density and zooplankton at four fixed sites and the other key variables at three of these sites biweekly …


Assessment Of Effectiveness Of Buffer Zones In Removing Impurities In Runoff From Areas Treated With Poultry Litter. Part Ii: Source Areas To Buffer Areas Ratio Effects, P. Srivastava, D. R. Edards, T. C. Daniel Jun 1995

Assessment Of Effectiveness Of Buffer Zones In Removing Impurities In Runoff From Areas Treated With Poultry Litter. Part Ii: Source Areas To Buffer Areas Ratio Effects, P. Srivastava, D. R. Edards, T. C. Daniel

Arkansas Water Resources Center Technical Reports

Vegetative filter strips (VFS) are known to reduce runoff losses of nutrients. solids. and other materials from land areas treated with fertilizers . Although VFS effectiveness is known to depend partially on the relative lengths of filter and pollutant source areas. there is little experimental evidence available to quantify this dependence. This is particularly the case when VFS are implemented down-slope of pasture areas treated with animal manures such as poultry litter. This study assessed the influences of pollutant source area (treated with poultry litter) and VFS lengths on VFS removal of total Kjeldahl nitrogen (TKN). ammonia nitrogen (NH3 -N …

Distribution And Ecological Significance Of On-Farm Bush Remnants In The Southern Wheatbelt Region Of Western Australia - Phase Ii - Save The Bush Project, E A. Griffin

All other publications

This is the second phase of the Southern Wheatbelt Region Remnant Vegetation project aimed at surveying pieces of bushland in the 'Great Southern' of Western Australia. The first phase was completed during 1991-1992 and covered 11 shires

The aims of this survey were to document what is left (as on-farm remnant bush areas), so that the information is a available for use by the wider farming community (see also Mollermans 1992a, b).' In addition, native vegetation was defined as "endemic floral ... communities which have not been planted and which are in place as a result of natural processes" (ACF …


Brine Shrimp Ecology In The Great Salt Lake, Utah, Wayne A. Wurtsbaugh Jun 1995

Brine Shrimp Ecology In The Great Salt Lake, Utah, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

Hypersaline lakes are noted for their simple communities which facilitate understanding ecological interactions (Williams et al. 1990; Wurtsbaugh 1992; Jellison and Melack 1988). Nevertheless, we still cannot easily predict how environmental changes will effect the population dynamics in these lakes, at least in part because even these simple ecosystems may be more complex than we .realize. Many hypersaline lakes are dominated by the brine shrimp Artemia spp. The production of brine shrimp is often very high because the terminal, saline lakes accumulate nutrients that make them rich, and because the short food chains in them (nutrients-->phytoplankton-->brine shrimp) minim …

The present project deals with the study of coastal sediments along the Eastern Coast of United Arab Emirates (U.A.E.), and it has two main objectives:

  • Determination of heavy mineral contents of the coastal sediments in relation to the geology of the hinterlands.
  • Trace metals studies (Zn, Pb, Ni, Cr, Cu, Co, Cd, Mn and organic carbon) as a measure of environmental pollution.

The results of heavy minerals separation (fine sand fraction) from the Eastern Coast sediments reflect that these sediments are generally rich in heavy minerals content with percentages reaching up to 78% with some areas reaching upto 98%. The …


Management Of Hospital Wastes In The United Arab Emirates, Hanan Ahmed Ali Shuwaiter Jun 1995

Management Of Hospital Wastes In The United Arab Emirates, Hanan Ahmed Ali Shuwaiter

Theses

The gradual expansion and development of new public and private medical complexes have resulted in the production of various types of wastes which include hazardous materials. Such wastes require appropriate handling and management schemes based on safer disposal methods. There are no reliable figures for quantifying the amount of medical waste generated or appropriate legislation and guidelines for handling, storage, transport and disposal of medical waste in the United Arab Emirates. No previous detailed studies have been conducted for the management of medical waste in the UAE. In general there is insufficient awareness of the health hazard associated with improper …

Whaling Error, Robert L. Brownell Jr. May 1995

Whaling Error, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

You published recently (Nature 374, 587; 1995) a report headed "Error re-opens 'scientific' whaling debate".

The error in question, however, relates to commercial whaling, not to scientific whaling. Although Norway cites science as a basis for the way in which it sets its own quota. scientific whaling means something quite different. namely killing whales for research purposes. Any member of the International Whaling Commission (IWC) has the right to conduct a research catch under the International Convention for the Regulation of Whaling. 1946. The IWC has reviewed new research or scientific whaling programs for Japan and Norway since the …


Transitions In Masculinity And Hemingway's Developed "Code", Daniel Polk May 1995

Transitions In Masculinity And Hemingway's Developed "Code", Daniel Polk

Honors Theses

The "Hemingway Code" is much more than two words that fit nicely together for a scholar's usage; the words signify a much deeper championing of masculinity, almost a haunting presence. For Ernest Hemingway living life every day, every moment with its fullest masculine fervor, became an obsession, a never-ending quest to be at one with the attitude of never complaining, never crying out, panicking, thinking too much, or regretting. To live a manly life in a series of tactical victories, performed with steadfast ritualistic mannerisms, is to embody masculinity, and therefore the "Hemingway Code."
