Survival Of Trout Strains As Affected By Limnological Parameters, Wayne A. Wurtsbaugh
Survival Of Trout Strains As Affected By Limnological Parameters, Wayne A. Wurtsbaugh
Watershed Sciences Faculty Publications
Prior work at East Canyon Reservoir, Utah indicated that adult trout are important predators of stocked juvenile rainbow trout. Brown trout, in particular, were exclusively piscivorous when th~y exceeded 185 mm standard length. Fish became increasingly important in the diet of cutthroat trout greater than 330 mm. The purpose of this study was to further document the effect of adult trout on survival of juvenile rainbow trout in mid-elevation reservoirs. Causey Reservoir was chosen because it was thought to contain large brown and cutthroat trout and had not been intensively studied during the last eight years.

Oyster Spatfall In Virginia Rivers: 1988 Annual Summary, Bruce Barber, James Whitcomb
Reports
The Virginia Institute of Marine Science (VIMS) conducts annual surveys of oyster spatfall ( or "sett.ing") in Virginia waters. This survey provides an estimate of the potential of a particular area for receiving a "striken or set of oysters and helps define the timiug of setting events. In 1988 spatfall was monitored from June 6 to October 16 at a total of forty-two stations (Figure 1). · During this period shellstrings were deployed at each station (0.5m off the bottom) on a weekly basis. A shellstring consists of 12 oyster shells drilled through the center and strung on a piece …
Cost-Effective Fire Management For Southern California's Chaparral Wilderness: An Analytical Procedure, Chris A. Childers, Douglas D. Piirto
Cost-Effective Fire Management For Southern California's Chaparral Wilderness: An Analytical Procedure, Chris A. Childers, Douglas D. Piirto
Natural Resources Management and Environmental Sciences
Fire management has always meant fire suppression to the managers of the chaparral covered southern California National Forests. Today, Forest Service fire management programs must be cost effective, while wilderness fire management objectives are aimed at recreating natural fire regimes. A cost-effectiveness analysis has been developed to compare fire management options for meeting these objectives in California's chaparral wilderness. This paper describes the analytical procedure using examples from a study currently being conducted for the Los Padres National Forest, and discusses some preliminary results.

Deployment : The tripods were assembled, tested and secured onboard the RIV Sea Diver, which left the Little Creek Amphibious Base in Norfolk, Virginia early on 26 September. While underway to the deployment site, the continuous surface water conductivity and temperature survey was run and several CTD casts were made. The tripods were deployed on 26 September and secured to the sea floor with sand anchors by VIMS divers. The R/V Sea Diver then began the series of on/off shore transects at the tripod deployment site for approximately 12 hours. The vessel returned to port on 27 September .

The Synthesis And Evaluation Of 5-Phenyloxazolidines As Potential Cardiovascular Drugs, Tammy C. Wang
The Synthesis And Evaluation Of 5-Phenyloxazolidines As Potential Cardiovascular Drugs, Tammy C. Wang
Chemistry & Biochemistry Theses & Dissertations
Drugs such as adrenoceptor antagonists and certain centrally acting agents are known to lower blood pressure and thus serve as clinically useful antihypertensive agents. Norepinephrine 4, a natural ∝-adrenoceptor agonist, is the major agent associated with increased blood pressure in the periphery. Based on a careful structure-activity comparison, a series of substituted oxazolidines, 20, 21, 22 and 23, have been designed as possible antihypertensive candidates. Specifically, 22 and 23 have been synthesized to serve as potential norepinephrine antagonists.
Preliminary evaluation of these compounds indicated that they were not antihypertensive in nature. The more active compound, 23, …

OES Theses and Dissertations
To determine the effects of salinity on adult and larval survival, egg deposition, egg hatching and metamorphosis, shrimp were held in the laboratory and exposed to treatment salinities ranging from O to 35 ppt. Tests on adult survival indicate a 96 hour LC-50 between 30 and 35 ppt. Longer term tests on adult survival showed high mortality in salinities greater than 15 ppt. Shrimp became ovigerous in salinities of O - 20 ppt with egg hatching and metamorphosis limited to O - 5 ppt. Starved- larvae hatched from field captured ovigerous females in O ppt were able to metamorphose in …

SECTION I
A method was developed to analyze Acetylene, Ethylene, Ethane, Propylene and Propane levels in the ambient air. Chlorinated compounds within the operation retention time, Methyl chloride, Methylene chloride and Vinyl chloride, were monitored also.
Four sampling sites are located at Carteret, Elizabeth, Newark and Montville in New Jersey. Samples were taken during the summer of 1988. Two sample duration periods utilizing 12 and 6 liter stainless steel canisters were set up to take 24 hour air samples and instantaneous air samples (5 minutes collection period).
The average levels of Acetylene, Ethylene, Ethane, Propylene and Propane at the four …

Theses
PART A: An investigation of total human exposure to an environmental pollutant is described. The study is being conducted in a community impacted by a foundry suspected to be a dominant local source of benzo(a)pyrene (BaP). The research aims to assess the relative contributions of indoor and outdoor sources and to measure BaP in media including indoor air, outdoor air, food and water.
PART B: A method for biological monitoring of exposure to benzo(a)pyrene, a representative polycyclic aromatic hydrocarbon (PAH), has been developed. The analytical procedure includes extraction of PAH and PAH metabolites from urine using commercial cartridges containing c …

KWRRI Research Reports
The movement of atrazine, cyanazine, and simazine from the site of application was monitored under conventional, reduced, and no-tillage conditions. Less water and soil was lost from the no-tillage and reduced tillage conditions. Conventional tillage conditions had about 66,000 L/ha runoff in 1986-87 and about 123,000 L/ha runoff in 1987-88. Seasonal rainfall was 885 mm in 1986-87 and 397 mm in 1987-88. The rainfall intensity was greater during the first two events in 1987 than the corresponding events in 1986. The first rainfall event in 1986 accounted for 91, 89, and 78% of the total seasonal loss of atrazine, cyanazine, …

Reports
Three sets of twelve oysters from the ,James River were placed in three recirculating aquaria dosed with the radioactive tracer zinc-65. All aquaria had the same amount of river bottom sediment which was kept in suspension by the water movement caused by aeration; one aquarium had twice as much tracer as the other two. The salinity of one of the low dose aquaria and. the high dose aquarium was maintained at 18 0/00: the other low dose aquarium was maintained at 1:2 0/00. All other factors were kept constant. Sediment-water-tracer mix was added to the aquaria every 12 hours. Water …

Traditionally most grain is stored in circular type bins which provide a convenient means for handling and management. With the excess grain production and government loan programs of the past few years, some producers have used rectangular structures and covered piles to complement their round storages. The recommended management practices used with round bins are still required in those alternative storages and may be more critical in obtaining a quality end product.
One such recommended practice used with round bins is aeration. This practice is used to maintain a uniform temperature in the grain mass, preventing condensation and "hot" spots …

Indian reservations constitute about 2.5% of all land in the country and 5% of all land in the American West. During the last two decades, Indian natural resources issues have moved to the forefront as tribal governments have dramatically expanded their regulatory programs, judicial systems. and resource development activities. This major symposium will address current developments and assess likely future directions in the areas of tribal, federal, and state regulation; tribal-state intergovernmental agreements; financing; mineral …
