The Effect Of Sodium Chloride On Beta-Hemolytic Streptococci, Bola Fashola
Masters Theses & Specialist Projects
The drug of choice for the treatment of Stieptococcal pharyngitis is penicillin G. However, a common home remedy prescribes the use of salt-water solutions for gargling.
Members of Beta -hemolytic streptococcal groups A, B, and C were isolated from the upper -respiratory tracts of patients diagnosed as having streptococcal pharyngitis. These cultures we:e obtained from HCA Greenview Hospital (Bowling Green, Kentucky) and used to study the effects of sodium chloride on the isolates.
The minimum inhibitory concentration of sodium chloride was determined for each of eight hospital isolates. Croup A streptococci were inhibited at a concentration of 7.2% sodium chloride …

Conservation Tillage And Irrigation Effects On Corn Root Development, R. L. Newell, Wallace Wilhelm
Conservation Tillage And Irrigation Effects On Corn Root Development, R. L. Newell, Wallace Wilhelm
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
The effects of conservation-tillage practices on the root environment of corn (Zea mays L.) may differ with varying amounts of irrigation. Dryland, 50% irrigation, and 100% irrigation treatments were applied in combination with disc, no-tillage, and a postemergence chisel treatment designed to allow rapid infiltration of irrigation water. The study was conducted during the 1980 growing season at the Nebraska Agricultural Experiment Station near Mead, NE, on a Sharpsburg silty clay loam (fine, montmorillonitic, mesic Typic Argiudolls). Root samples were taken to 1.50 m in 0.15-m increments. Sampling was done at 60 (V8), 77 (V14), and 90 (R2) days …

A Development Plan For The South Coast Inshore Trawl Fishery, Fisheries Department Of Western Australia
A Development Plan For The South Coast Inshore Trawl Fishery, Fisheries Department Of Western Australia
Fisheries management papers
In March 1986 discussions were commenced between officers of the Fisheries Department and the Australian Fisheries Service concerning management measures for trawl fishery in the Great Australian Bight. These measures were considered necessary as a Western Australian Company (Toskel Fishing Co.) had commenced fishing the area. Given the excess fishing capacity in other Australian trawl fisheries it was considered advisable to institute management at an early stage and control development of this deep water fishery. Concurrent with these developments, mainly directed towards the control of larger trawlers in deeper waters, several small Western Australian trawlers operating out of Esperance and …

Lake Mead Prefertilization Study: Preliminary Nutrient Enhancement Studies In Lake Mead, Richard P. Axler, Larry J. Paulson, Patrick J. Sollberger, Donald H. Baepler, U.S. Bureau Of Reclamation
Publications (WR)
Studies conducted by the University of Nevada-Las Vegas (UNLV), the Nevada Department of Wildlife (NDOW), the Arizona Game and Fish Department (AGFD), The Nevada Division of Environmental Protection (NDEP), and the United States Bureau of Reclamation (USBR) have identified decreased algal production as a major factor involved in the decline of the Lake Mead sport fishery. Phosphorus-laden silt particles in the Colorado River have been sedimenting out in Lake Powell since the completion of Glen Canyon Dam 286 miles upstream in 1963. This sharp decrease in phosphorus loading to Lake Mead (>5000 tons per year) has resulted in decreased …

Co2-Warming, Rising Sea-Level And Retreating Coasts: Review And Critique, Edward A. Bryant
Co2-Warming, Rising Sea-Level And Retreating Coasts: Review And Critique, Edward A. Bryant
Faculty of Science - Papers (Archive)
A CO2-warming atmospheric scenario, whereby increased concentrations of 'greenhouse' gases result in warmer temperatures that either melt near-polar ice or cause thermal expansion of ocean waters, thus leading to increased sea-levels and exacerbated coastal erosion, assumes fundamental but unproven cause-and-effect relationships. General circulation models have reinforced claims of an accelerated warming and indirectly given support to the complete scenario, but ignore the point that global climate and not just air temperatures have changed over the past century. Indeed, it is difficult to prove that air temperatures have warmed naturally outside of urban centres over this period. To attribute recent temperature …
The Impact Of Weather On Kingbird Foraging Behavior, Michael T. Murphy
The Impact Of Weather On Kingbird Foraging Behavior, Michael T. Murphy
Biology Faculty Publications and Presentations
Foraging data on Eastern Kingbirds (Tyrannus tyrannus) were collected during the early breeding season in eastern Kansas to test the hypothesis that foraging rate and other aspects of foraging behavior vary with weather. Foraging characteristics of five additional kingbird species were also examined to assess Fitzpatrick's (1980) generalization that kingbirds (Tyrannus spp.) are aerial hawking specialists. In Eastern Kingbirds, total foraging rate was independent of air temperature, cloud cover, wind speed, and time of day, but the rate of aerial hawking varied directly with air temperature and inversely with cloud cover (both P < 0.05). Effects of the two variables were additive. The percentage of foraging movements that were aerial hawks also increased with temperature and declined with cloud cover, and, hover-gleaning and perch-to-ground sallying were observed mainly during cloudy weather. Sally (i.e., foraging flight) distance correlated directly with perch height and air temperature, and large insects were captured almost exclusively in long upward or horizontal flights. I interpret these data to indicate that foraging behavior and the capture of large, flying insects depends on weather because of how it affects the activity of insect prey. Foraging data on kingbirds support Fitzpatrick's generalization, but the relative use of aerial hawking varies considerably among species. Resident Tropical Kingbirds( T. melancholicus) are the most specialized foragers, whereas the migrant and widely distributed Eastern Kingbird appears to be the most generalized. Certain habitats also appear to favor the use of particular foraging methods (e.g., outward striking in grasslands and perch-to-ground sallying in drier, open habitats).
Potential For Hydrocyanic Acid Poisoning Of Livestock By Indiangrass, Kenneth P. Vogel, H. J. Gorz, Francis A. Haskins
Potential For Hydrocyanic Acid Poisoning Of Livestock By Indiangrass, Kenneth P. Vogel, H. J. Gorz, Francis A. Haskins
Department of Agronomy and Horticulture: Faculty Publications
Hydrocyanic acid or prussic acid poisoning of livestock by sorghums [Sorghum bicolor (L.)Moench] and sudangrasses [Sorghum sudanese (Piper) Stapf] is caused by the digestive liberation of hydrocyanic acid (HCN) from the cyanogenic compound, dhurrin [(S)-p-hydroxymandelonitrile ,β-D-glucopyranoside] found in tissue of these plants. Recent research documented that dhurrin is also present in indiangrass [Sorghastrum nutans (L.) Nash] seed- lings. The purpose of this study was to determine the hydrocyanic acid potential (HCN-p) of forage from established stands of indiangrass. Five cultivars representative of indiangrass germplasm of the Great Plains were sampled during the growing season for 2 years …
The Glycoprotein Toxin Of Bacillus Thuringiensis Subsp. Israelensis Indicates A Lectinlike Receptor In The Larval Mosquito Gut, Ganapathy Muthukumar, Kenneth Nickerson
The Glycoprotein Toxin Of Bacillus Thuringiensis Subsp. Israelensis Indicates A Lectinlike Receptor In The Larval Mosquito Gut, Ganapathy Muthukumar, Kenneth Nickerson
Papers in Microbiology
The mosquito-active protein crystals produced by Bacillus thuringiensis subsp. israelensis contain covalently attached aminosugars which are critical for their larvicidal activity. The 50% lethal concentrations toward Aedes aegypti larvae were increased up to 10-fold by mild periodate treatment, up to 40-fold by forming the protein crystals in the presence of tunicamycin, and up to 7-fold by the presence during the mosquito bioassays of N-acetylglucosamine or its trimer, triacetylchitotriose. Periodate-treated crystals and crystals formed in the presence of tunicamycin had greatly reduced binding capacities for wheat germ agglutinin, an Nacetylglucosamine- specific lectin. These results suggest that the B. thuringiensis subsp. …

Characterization Of The Lipopolysaccharide From A Rhizobium Phaseoli Mutant That Is Defective In Infection Thread Development, Russell W. Carlson, Stanislaw Kalembasa, Debra A. Turowski, Pappi Pachori, K. Dale Noel
Biological Sciences Faculty Research and Publications
The lipopolysaccharide (LPS) from a Rhizobium phaseoli mutant, CE109, was isolated and compared with that of its wild-type parent, CE3. A previous report has shown that the mutant is defective in infection thread development, and sodium dodecyl sulfate-polyacrylamide gel electrophoresis shows that it has an altered LPS (K. D. Noel, K. A. VandenBosch, and B. Kulpaca, J. Bacteriol. 168:1392-1462, 1986). Mild acid hydrolysis of the CE3 LPS released a polysaccharide and an oligosaccharide, PS1 and PS2, respectively. Mild acid hydrolysis of CE109 LPS released only an oligosaccharide. Chemical and immunochemical analyses showed that CE3-PS1 is the antigenic O chain of …

Female Dominance Among Purple Finches (Carpodacus Purpureus) In Winter Flocks, James W. Popp
Female Dominance Among Purple Finches (Carpodacus Purpureus) In Winter Flocks, James W. Popp
Field Station Bulletins
The dominance of females over males in winter flocks is rare. In this paper, I report on female dominance over males in winter flocks of Purple Finches (Carpodacus purpureus). Females won nearly all observed intersexual encounters and also differed from males in their use of agonistic displays. Female dominance has been reported for other species in the genus Carpodacus, but reasons for the occurrence of female dominance in this genus are unknown.
Three Decades Of Change In Three Southeastern Wisconsin Woodlots, Lawrence A. Leitner
Three Decades Of Change In Three Southeastern Wisconsin Woodlots, Lawrence A. Leitner
Field Station Bulletins
Three upland woodlots in southeastern Wisconsin, originally sampled by the Plant Ecology Lab of UW-Madison in 1949, were resampled in 1981. In general, red and white oaks were being replaced by more shade-tolerant species. Two of the sites, Zirbe's Woods and Petrifying Springs Woods, appear headed for complete domination by sugar maple. Thompson Woods, where maple was absent, was at an earlier successional stage. In Thompson Woods, basswood and white ash were becoming dominant.

The primary objective of this study was to evaluate the application of dispersant to spilled oil as a means of reducing adverse environmental effects of oil spills in nearshore, tropical waters. The results of numerous laboratory and field studies have suggested that dispersants may play a useful role in reducing adverse impacts on sensitive and valued environments such as mangroves, seagrasses, and corals. However, the use of dispersants has not been allowed thus far in most situations because of a lack of direct experimental data on the various effects of dispersants and the environmental trade-offs presumed to occur as a …
