Biospeologica Sovietica.Xlix. Le Premier Représentant Anophtalme Des Trechini (Coléoptères Carabiques) De La Ciscaucasie, S. I. Ljovuschkin

International Journal of Speleology

During a recent exploration of caves in western Ciscaucasia there was collected, among others, a new species representing a new genus of Trechini (Coleoptera, Caraboidea), the description of which is given here; it has been named Birsteiniotrechus ciscaucasiens n.gen., n.sp., in memory of Prof. J.A. Birstein, famous Soviet biospeleologist, the founder and promotor of the “Biospeologica sovietica” series who passed away recently (cf. I.J.S., 4, part.2). The interest of Birsteiniotrechus lies in the fact that, until now no troglobite or endemic species of Trechini was known from the Ciscaucasian mountains; this genus belongs to the phyletic series of Neotrechus and …

Spectrophotometric And Microbiological Determination Of The Stability Of Sodium Ampicillin As Affected By Ph, Enrico Frank Raffanti

University of the Pacific Theses and Dissertations

The specific purpose of this investigation was to determine the effect of pH on the stability of ampicillin sodium for injection. Then, to correlate this information, a pH profile may be established to predict chemical stability with ampicillin sodium alone or when other drugs may be included in the admixture. With a pH profile the pharmacist could predict the length of time after which more than a 10 percent loss of activity would occur. Stability measurements were to be accomplished through a microbiological assay after adding ampicillin sodium to different buffer solutions. At the end of four hours, eight hours, …

Optimizing Resistance Coefficients For Large Bed Element Streams, D. E. Overton, Harl E. Judd, C. W. Johnson

Reports

This is a report of a comparison of Darcy resistance coefficients calculafed for previously reported laboratory data and those calculated for large bed element streams. Large bed element (LBE) streams exist frequently in nature where rocks derived from valley walls or from channels cutting through ancient glacial or fluvial deposits are moved only under conditions of extreme flood. The height of bed elements is a significant part of the mean depth of flow. The stream gradients are high and are quite stable for all but the highest flows.

Development Of Regional Supply Functions And A Least-Cost Model For Allocating Water Resources In Utah: A Parametric Linear Programming Approach, Alton B. King, Jay C. Andersen, Calvin G. Clyde, Daniel H. Hoggan

Reports

The development and allocation of the water resourcse within a state require water planners to prepare plans far in advance of the actual time new facilities are required. It is not easy to identify and evaluate all the possible alternatives for providing water which incorporate broad objectives such as economic efficiency, social welfare, regional development, recreation benefits, and conservation of environment. Water resources development entails the modification of a natural hydrologic system to better meet man's needs. The interrelationships among elements of the hydrologic system to better meet man's needs. The interrelationships among elements of the hydrologic system are relatively …

Distribution, Growth, Selective Feeding, And Energy Transformations Of Young-Of-The-Year Blueback Herring, Alosa Aestivalis (Mitchill), In The James River, Virginia, Richard Greig Burbidge

Dissertations, Theses, and Masters Projects

Energy transformations and budget are computers for young-of-the-year blueback herring, Alosa aestivalis, in the James River, Virginia. Distribution, growth, and selective feeding are described. Fish and zooplankton collections were made at five stations in the main channel of the James RIver from June through November 1969. Two 24hr series of samples were collected in July and October 1968 in the Potomac River. A direct relationship existed between standing cropos of zooplankton and distribution, growth, and feeding of blueback herring. Zooplankton densities were highest upstream, where food consumption and growth rates were correspondingly highest. A progressive downstream decrease and upstream increase …

Ionization Mechanisms In Cesium, Yu Bong Hahn

Doctoral Dissertations

"Autoionizing states in Cs between 12 and 20 eV have been studied by electron impact. The retarding-potential-difference(RPD) method was used to obtain an electron beam with energy spread of about 0.1 eV. To determine the threshold energies, inelastically scattered electrons were analyzed by the trapped-electron method. We have been able to identify about 20 levels, and the agreement with spectroscopic data is excellent. A peak appearing at 12.80 eV is probably due to the quartet states observed by Feldman and Novick"--Abstract, page 2. "The structure in the electron impact ionization cross section in cesium can be partially accounted for by …

A Report On The Condition Of The Gascoyne Catchment, D G. Wilcox, E A. Mckinnon

Resource management technical reports

Severe flooding in Carnarvon followed heavy rains on the Gascoyne Catchment in February 1961. The flooding and erosion were extensive enough to suggest that run-off from the catchment was excessive. Lightfoot (1961)* reported that excess run-off was due to degradation of the catchment area. This report will describe the catchment area in terms of the degradation of its rangeland and its susceptibility to erosion.

Nonrandom Characteristics Of Common Stock Prices, Donald Leroy Gaitros

Doctoral Dissertations

"This study presents an application of operations research techniques to the development of stock price generation and simulation models to aid in the understanding of price movement. Relationships between stock price and volume and stock price and market averages which follow descernible trends and patterns are discovered. Technical trading rules are developed based on these relationships which empirically have shed doubt on the random walk hypothesis of price movement. This in turn gives evidences that technical analysis can be an aid to price forecasting"--Abstract, page ii.

Gas-To-Particle Conversions Of So₂-No₂-H₂O-Air Gas Mixtures Under Specific Uv Irradiation, James Leonard Fowler

Masters Theses

"In these series of experiments, mixtures of sulfur dioxide and nitrogen dioxide were irradiated in an absorption cell with monochromatic radiation found in the tropospheric region of the atmosphere. The irradiated mixtures were then introduced into a Wilson type cloud chamber to investigate the effects of these specific wavelength induced gas to particle conversions on nucleation. Results showed that sulfur dioxide could not be the sole agent for the formation of condensation nuclei. A mixture of sulfur dioxide and nitrogen dioxide irradiated at 3660 angstroms produced copious droplet formation identifying nitrogen dioxide as an integral reactant in nuclei production"--Abstract, page …

Computerized Registration For High Schools, Kenneth Lee Fore

Masters Theses

"The guidance personnel in a high school are often burdened with the duty of hand scheduling the student's courses. Using the computer as a sub-optimizing tool in the registration of students, however, can cut scheduling time dramatically and relieve the guidance department of an onerous chore. The technique described in this investigation uses a conflict matrix that schedules the student's request and keeps the class load level within the course sections. A search of the schedule array for each course request may uncover a conflict. If no conflict occurs the course is scheduled and the remaining courses for this student …

Development Of Techniques For Distribution Of Baits To Raccoon For Chemosterilant Studies, Richard L. Nelson

Electronic Theses and Dissertations

Sudan Red IV, Sudan Black B, and demethylchlortetracycline (DMCT) were tested as physiological markers in baits for raccoon (Procyon lotor). DMCT was readily detected in the jawbone of raccoons given 50 mg when examined under an ultraviolet light at period of 7, 30, 75, and 450 days following treatment. Seven days after administering 75 mg of Sudan Red IV, it could not be detected in fat deposits. Sudan Black B, administered in similar dosage, could not be detected at 30 days. A total of 1826 chicken eggs containing 50 mg DMCT was distributed on a 25 square-mile study area between …

Effects Of Diethylstilbestrol On Reproduction In The Black-Tailed Prairie Dog, Donald G. Pfeiffer

Electronic Theses and Dissertations

Research was conducted in southwestern South Dakota in 1970 and 1971 to obtain information on the reproductive cycle of the black-tailed prairie dog (Cynomys ludovicianus) and to test effectiveness of diethylstilbestrol as a reproductive inhibitor. Embryo body lengths from 10 pregnant females were compared to body lengths of 14 known day-old young to learn the peak breeding period when an estrogenic chemosterilant would be most effective. Conception dates were obtained for three females by backdating the gestation period. The breeding peak was found to occur in late February and early March in South Dakota. Nine of 11 Prairie dogs were …

Food Selectivity Of The Black Bullhead (Ictalurus Melas, Rafinesque) In Lake Poinsett, South Dakota, Andrew J. Repsys

Electronic Theses and Dissertations

The food habits of young-of-the-year, subadult and adult black bullheads were studied in Lake Poinsett, South Dakota, from March, 1970, to April, 1971. Two hundred twenty young-of-the-year (37-87 mm total length) fed primarily on limnetic cladocerans and copepods. Leptodora and Diaphanosoma comprised 86.5% of the total food volume. Chironomid larvae and pupae made up 5.6% of the total. Other benthic organisms and littoral cladocerans together contributed less than 1%. Stomach contents of 608 subadult and adult black bullhead (143-304 mm total length) indicated significant seasonal vairaiton in diet. Daphnia pulex and chronomid larvae were important food items in winter. Bullheads …

Food Habits Of Fish In A Multispecies Farm Pond, Thomas W. Gengerke

Electronic Theses and Dissertations

Food habits of yellow perch, bluegill, and black crappie were studied during 1970 and 1971 in Abbey Pond, South Dakota. Aquatic insects, zooplankton, mollusks, and fish were the most frequently consumed food items by the three species. Yellow perch led primarily on aquatic insects, zooplankton, and mollusks. Aquatic insects were dominant (by volume) in 40.0 and 61.5 percent of the samples respectively for the two years. Zooplankton, mollusks, aquatic insects, and bryozoans were the dominant food items by volume of adult bluegills. On an annual basis aquatic insects were the most important food item in the diet. Adult black crappies …

Waterfowl Production In The James River Valley Of South Dakota, William E. Wheeler

Electronic Theses and Dissertations

A study of waterfowl production was conducted on two study areas in the James River Valley of South Dakota in 1971 and 1972. Its objectives were to measure rates of reproductive success and to determine the effect of land use and other influences on duck production. The five most abundant species of nesting ducks were blue-winged teal (Anas discors), mallard (platyrhvnchos), gadwall (A. strepera), shoveler (clypeata), and pintail (acuta). Seventy-two percent of the wetland habitat on the study areas consisted of temporary (Type l and Type 3) water areas. Only 3.9 percent of the wetlands represented semi-permanent (Type 4) and …

Effects Of Polychlorinated Biphhenyls In The Ring-Necked Pheasant, Robert Bernard Dahlgren

Electronic Theses and Dissertations

In 1970 and 1971, cock pheasants (Phasianus colchicus) were given single capsules weekly containing 0 and 25 mg polychlorinated biphenyls (PCB), Aroclor 1254, and hens were given O, 12.5, and 50 mg. Egg production was reduced (P<0.01) in the hens given 50 mg PCB both years. Fertility, determined by visual inspection of incubated eggs, was unaffected by PCB. Hatchability was lowest in the group of hens given 50 mg in both years but significantly lower (P<0.01) only in 1971. PCB adversely affected the viability of the embryo both years, as the number of eggs pipped but not hatched in PCB groups was higher (P<0.05). PCB did not affect eggshell thickness. Behavior on the visual cliff shortly after hatching was affected among offspring of hens given 50 mg PCB in 1970 (P,0.01). Offspring of hens given 50 mg chose the visually-deep side of the cliff. No differences in behavior on the visual cliff were evident in 1971. Response to hand catching of offspring was affected in 1970 (P <0.01). The ability of penned pheasants to avoid hand capture was least where both parents received PCB, followed by those where hens only, cocks only and neither parent received PCB. No differences in response to hand capture among groups were found in 1971. Weights of chicks from hens on 50 mg were lower (P<0.01) at 6 weeks of age in 1970. This effect was not seen in 1971. Survival of chicks in brooders to 6 weeks of age was lower (P<0.01) in offspring of hens given 50 mg PCB weekly in 1970. No differences were found among offspring of treatment groups in 1971. Survival from 6 weeks of age to fall was similar in all groups. Overall survival from hatching to fall was less (P<.0.05) in offspring of hens given 50 mg weekly in both years combined. No differential effect was found between sexes for survival. PCB in doses varying front 10 mg to 210 mg daily caused hyper-excitability, weakness, tremoring, lack of appetite, lack of feathers, and a comatose death. Birds 11-weeks old given 10 or 20 mg PCB daily, birds 6 to 9 months old given 50 or 100 mg each 3.5 days, and adult hens given up to 50 mg once a week continued to eat. Eleven-week old birds given 210 mg daily stopped eating or those given 210 mg daily, the heaviest birds lost the greatest percentage of their weight (15 to 31 percent) before death occurred (1.3 to 4.3 days). Birds intentionally starved at the same time lost a greater percentage of weight (27 to 51 percent) before death (2.3 to 8.6 days). Some adult hens were given a single 50-mg capsule and samples of whole body, brain, liver, muscle, eggs, and feces were analyzed to determine patterns of storage and excretion. Levels of PCB were highest at 12 hours after capsule administration. Residues were highest in liver, followed by brain and muscle over 28 days following the single 50-mg capsule. From 94 to 98 percent of the administered dose was absorbed and 40.5 mg of the 50mg were in the body after 28 days. Hens were in a state of low egg production and excreted 4.2 mg in the eggs and 4.0 mg in the feces over 28 days. Excretion in the egg could be an important means of ridding the body of PCB. Four hens from the 1970 breeding experiment, given 17 capsules weekly containing 12.5 mg PCB and killed 1 week following the last capsule, had from 37 to 56 percent of the administered dose in their bodies. Four hens on the 50-mg level in 1970 had from 60 to 82 percent of the dose given. Five hens given 12.5 mg weekly for 16 weeks in 1971 had an average of 23.8 ppm PCB in their bodies 1 week after the last capsule, three hens had an average of 13.6 ppm after 3months on a clean diet, and three others had an average of 20.9 ppm after 6 months. Excretion was variable and slow. An analysis of brain, liver, and muscle tissues from dead and surviving birds fed PCB at various levels showed that brain residue levels from 300 to 400 ppm wet weight were indicative of death from FCB toxicosis. Liver and muscle levels were too variable to be useful in assessing cause of death. Administration of PCB decreased weights of heart and spleen (P <0. 01) at all levels given and increased weights of kidneys and livers in birds given 10- and 20-rng doses daily (P <0. 01) but not in birds given 210 mg daily. Splenic atrophy, where spleens were small, pale-tan color, and had wrinkled capsules resulting from depletion of lymphatic nodules, was characteristic of birds given PCB. PCB and dieldrin were given singly and jointly, and only additive, not synergistic, effects were noted. Livers of wild pheasants from Pennsylvania, Indiana, and South Dakota had no more than 2 ppm PCB. This indicates low-level contamination.

Use Of Waterfowl Production Areas By Ducks And Coots In Eastern South Dakota, Spencer Vaa

Electronic Theses and Dissertations

The use of Waterfowl Production Areas (WPA) by American coots (Fulica americana) and ducks was studied during 1970 and 1971 in east-central South Dakota The Eriksrud WPA, a type IV wetland with 55 acres of water area and 35 acres of upland, contained 188 coot nests during the 2-year study. Of the 188 coot nests, 178 hatched for a success rate of 95 percent. Average clutch size of 130 completed clutches was 8.4. Average size of 21 coot broods from 4 to 6 weeks of age was 6.1. Coot production on the Eriksrud area was estimated at 543 young per …

Use Of Eelctrophoresis To Determine Populations Of Pheasants In South Dakota, David George Montag

Electronic Theses and Dissertations

The ring-necked pheasant (Phasianus colchicus) is an important game bird, and various management techniques have been implemented in its behalf. One of the most common practices has been transplanting or stocking wherein pheasants are introduced into an area with a depleted population in hopes of increasing pheasant production. The effects of such programs are difficult to evaluate since there is no way of knowing if the introduced birds are in any way responsible for production changes which subsequently occur. If the taxonomic characteristics of the native and the introduced populations could be determined, the effect that introduced birds have on …

Acute Toxicity Of Unbleached Kraft Mill Effluent (Ukme) To The Oppossum Shrimp, Neomysis Americana Smith, Fred Jacobs

Dissertations, Theses, and Masters Projects

96-hour TL50 values of unbleached kraft mill effluent (UKME) for Neornysis arnericana were found to range from concentrations of 3.29 to 6.85% at 26-28 C and 3.90 to 7.30% at 16-18 C. Differences between batches of effluent proved insignificant in experiments at each temperature regime. Furthermore, UKME did not lose its toxicity, when stored for 5 to 7 days at 4 C. A concentration of 20% effluent killed 100% of the organisms in 8 of the 12 bioassays. Slope functions and confidence limits of TL50 were calculated. This dissertation is from the Joint Program Degree from the College of William …

Time Resolved Measurements Of Droplet Growth In A Wilson Cloud Chamber, Michael Anthony Vietti

Doctoral Dissertations

"The growth rates of water drops in a Wilson expansion cloud chamber are measured with air, argon and helium as the carrier gas, in the size range of .5 to 10 microns. The drops growing in the supersaturated chamber exhibit oscillations in the scattered intensity as predicted by Mie theory. Scattered intensity is measured at 30 degrees to the He-Ne laser beam. Supersaturation ratios during growth range from S =1.2 to S = 3.5 for all three gases. The initial temperature is measured and the pressure is monitored continuously so that droplet growth theory can be compared with experiment. Three …
