On Local Stresses And Spring Constants Of Pipe-Nozzle Connection, Hson-Chih Sun

Dissertations

This thesis presents a comprehensive study of local stresses and spring coefficients of pipe with a nozzle connection, analyzed by the finite element method (FEM). Six types of loading are discussed: radial force, circumferential moment, longitudinal moment, circumferential shear force, longitudinal shear force, and torsional moment.

For the local stresses, the bending and membrane stress factors due to each of these loadings are presented in a series of plots with various gamma (piping radius/thick-ness) and beta (nozzle radius/pipe radius) values. These stress factors will readily replace those previously published in WRC No. 107. This work not only gives more accurate …

Farm Structure And Use Of The Conservation Reserve Program Of The 1985 Farm Bill, Joseph N. Kairumba, Gerald C. Wheelock

Journal of Rural Social Sciences

Within the conservation and production objectives that form the current Farm Bill, there are a range of options that encourage uniquely tailored farm plans for each farm and landowner (LO) situation. In this attempt to predict use of one option, the Conservation Reserve Program (CRP), three broad sets of farm structure variables were employed. These were farming scale, planning horizon, and farm specialization. A two-stage systematic sample of 437 farm parcels from county ASCS lists resulted in 187 land owner interviews for discriminant analysis. Participation in CRP was most discriminated by two farm size variables--crop acres and gross farm income. …

Eimeria Sp. (Apicomplexa: Eimeriidae) From Wyoming Ground Squirrels Spermophilus Elegans, And White-Tailed Prairie Dogs, Cynomys Leucurus, In Wyoming, Larry M. Shults, Robert S. Seville, Nancy L. Stanton, George E. Menkens Jr.

Great Basin Naturalist

Six species of the coccidian genus Eimeria (E. larimerensis [prevalence = 17%], E. bilamellata [12%] E. beecheyi [34%], E. morainensis [43%], E. callospermophili [21%], and E. spermophili [5%]) were recovered from Wyoming ground squirrels (Spermophilus elegans elegans) collected during 1983, 1984, 1985, and 1986. Infected ground squirrels were found to harbor from one to five species simultaneously. The 1007 hosts examined were collected from two different habitats: (1) a xeric desert shrub-steppe and (2) an irrigated alfalfa-brome field. All species of Eimeria occurred at each study site during all years, although the prevalence of each species varied …

Effects Of Prairie Dog Rodenticides On Deer Mice In Western South Dakota, Michele S. Deisch, Daniel W. Uresk, Raymond L. Linder

Great Basin Naturalist

Mortality of nontarget small mammals was determined after application of three black-tailed prairie dog (Cynomys ludovicianus) rodenticide treatments (prebaited zinc phosphide, prebaited strychnine, and strychnine alone) in western South Dakota. Immediate (September 1983) and long-term (September 1983 through August 1984) impacts on deer mouse (Peromyscus maniculatus) relative densities were evaluated and the three rodenticide treatments were compared for efficacy. The three treatments had no significant (α < .10) immediate impacts on deer mouse relative densities, although zinc phosphide did lower them; that impact was not, however, long term. Long-term impacts of the two strychnine treatments were variable, with an increase in deer mouse densities with the strychnine only treatment. Overall, comparisons among the three treatments indicated that zinc phosphide was more effective than either strychnine treatment in reducing deer mouse densities.

Reproduction Of Three Species Of Pocket Mice (Perognathus) In The Bonneville Basin, Utah, Kenneth L. Cramer, Joseph A. Chapman

Great Basin Naturalist

Data on reproduction of three species of pocket mice (Perognathus) occurring in northern Utah are summarized. Perognathus parvus and P. formosus bred in spring but not the remainder of the year. This occurred despite mild fall and winter temperatures and shallow snowcover. Litter sizes for P. parvus and P. formosus were similar to those reported by previous investigators. A small sample of P. longimembris indicated they may have much larger litters (averaging 5.78 young) than previously reported for laboratory populations. Adult body mass was positively correlated with testis mass in all species, and with litter size in P. …

The Adaptations Of Farmers In An Era Of Declining Groundwater Supplies, Don E. Albrecht

Journal of Rural Social Sciences

In recent years it has become increasingly apparent that modem agricultural practices are resulting in a wide array of environmental problems, and in particular resource depletion problems. As of yet, however, there has been a relative lack of research on the adaptations made by farmers when faced with the depletion of an important resource. This paper helps address this void by exploring the adaptations of farmers (N = 700) in the Texas High Plains to the depletion of their primary source of irrigation water--the Ogallala Aquifer. It was found that the proportion of farm operators who had adopted each of …

Human Resources In The South: Rural Sociology In The 1990s, Peggy J. Ross

Journal of Rural Social Sciences

This article focuses on the problem of human resources in the South during the 1980s. The author contends that the problem is especially critical in the rural South, where the impacts of widespread rural economic stress in the eighties contributed to further underdevelopment of already limited human resources. Educationally, the South not only lags other regions, but the rural South lags the urban South. Furthermore, a wide gap exists in the educational attainment of southern rural blacks and whites. It is argued that the development of an adequate human resources base in the rural South begins with building initiative and …

1890 Institutions' Extension Program And Rural Development, Adell Brown Jr.

Journal of Rural Social Sciences

The black land-grant colleges' contributions to developing the rural South are traced back before they were added to the land-grant system by the passage of the Morrill Act of 1890. The 1890 Extension target clientele are small farmers and limited resource persons who were not being reached by the conventional delivery system. Before 1972, the 1890 institutions primarily assisted the 1862 universities to serve black farmers and provide training and housing for black specialists and agents. In 1972, the passage of USDA Appropriation Act, under 3(d) section of the Smith-Lever Act, provided funds for the 1890 institutions to fulfill the …

Obstacles And Opportunities: Funding Research At The 1890 Land Grant Institutions, Alton Thompson

Journal of Rural Social Sciences

Similar to other university faculties, faculty members at 1890 land grant institutions are expected to support their research programs with grants from sources outside their institutions. Although the expectation of securing grants has not received the public attention that the "publish or perish" dictum has, faculty at the 1890 institutions seeking promotion and tenure must increasingly demonstrate that they can procure grant funds. Numerous inhibitive factors, however, tend to attenuate the success of 1890 faculty in obtaining research grant funding and in implementing such research projects. In this study, three key factors are examined: political, research infrastructure, and faculty initiative. …

Ecological Review Of Black-Tailed Prairie Dogs And Associated Species In Western South Dakota, Jon C. Sharps, Daniel W. Uresk

Great Basin Naturalist

Black-tailed prairie dogs (Cynomys ludovicianus) once occupied extensive areas throughout the Great Plains. In recent years massive control programs have been initiated to reduce prairie dog populations, primarily to benefit the livestock grazing industry. Currently in western South Dakota most prairie dogs are found on public lands. Control programs using toxicants for prairie dogs have been found to be economically unfeasible when not combined with reductions in livestock grazing. Control programs also have negatively impacted some nontarget species of birds and small mammals. Livestock grazing is directly related to prairie dog densities. Prairie dog and livestock grazing activities …

Institutions Under Influence: The Case Of Knowledge Stratification Within The U.S. Land Grant System, Rosalind P. Harris

Journal of Rural Social Sciences

The U.S. land grant system is notably stratified in its distribution of knowledge and power. In the upper strata are historically white land grant (HWLG) institutions often referred to as "1862 Institutions," which command power and resources from their historic ability to produce the agricultural and scientific knowledge supportive of state and national economic development goals. In the lower strata are historically black land grant (HBLG) institutions often called "1890 institutions." They struggle against the historical conditioning that has, until recently, restricted their efforts in producing knowledge to the manual applications and teaching of farming. This article examines how historical …

Spatial Pattern And Interference In Piñon-Juniper Woodlands Of Northwest Colorado, Charles W. Welden, William L. Slauson, Richard T. Ward

Great Basin Naturalist

The local spatial arrangement of the coniferous trees Pinus edulis and Juniperus osteosperma was mapped in two woodland stands and measured in two shrub-dominated stands in the semiarid Piceance Basin of northwest Colorado. In the woodlands, small trees were often clumped, while medium and large trees were either randomly or uniformly dispersed. Significant regressions were obtained between a tree's basal area or canopy area and the area of its Dirichlet domain (the region closer to it than to any other tree). Both findings from the woodland stands accord with results obtained by other workers in other vegetation. Like earlier workers, …

Estimating 3-D Motion And Structure Parameters Of A Rigid Planar Object By Establishing Landmark Correspondences, Herman Agustiawan

Theses

The application of a landmark based approach in recognizing 3-D rigid planar objects[3] along with two different motion and structure estimation algorithm [21][23] have been studied to perform motion and structure estimation tasks of moving objects. The recognition algorithm is based on a sphericity value derived from affine transformation that maps feature points in the object under observation from first to second view in the 2-D image space. The motion and structure estimation algorithm is based on a unique mapping given four or more feature point correspondences.

More than ten experiments have been done including small and large rigid motions. …

Simulation Based Modeling And Scheduling Of A Generalized Flow- Line, Srinivas Anne

Theses

Simulation is a state of art technique, widely used to analyze the behavior of complex and dynamic real time systems. This study consists of two parts. The first part involves in the development of a simulation model of a real time flow line, used to assemble Printed Circuit Boards. The desired performance measures of the system, like, utilization, starving, blocking, failure and maintenance are recorded. The model developed can be used as a test pad to analyze scheduling rules and heuristics. This is illustrated in the second part of the study which consists of studying the behavior of the Apparent …

Implementation Of Object Oriented University Database Using Vodak/Vml-0 Prototype, Abhay V. Bhave

Theses

In recent years object - oriented programming has gained a tremendous popularity in the design and implementation of emerging data - intensive application systems. Object oriented knowledge based approaches have proved to be very powerful vehicle when developing, integrating complex systems.

Using a University database demonstrated here is an object oriented model. This model uses VODAK/VML-0 prototype which was developed by GMD - IPSI, Darmstadt FRG. The Conceptual Schema of this database was done using The Dual Model, but as the current VODAK/VML version does not support dual model, the schema was modified before use. There are 167 classes defined …

A Transistor Delay Model Based On Charge Conservation, Bharatsingh K. Bisen

Theses

Delay information of a circuit is often used in the areas of timing verification, timing analysis, race detection and circuit optimization. Given a circuit its delay can be estimated by various simulation techniques. SPICE is one of the simulation techniques, but it is seen that with the increase in the complexity of the circuit the SPICE circuit simulation technique to obtain delay information become cumbersome and computationally too expensive. So as to overcome the above disadvantages of the circuit simulation technique to obtain delay information various timing delay models were developed. However general survey of most of these timing delay …

A Pc Based Computer Model With A Postprocessor For The Movement Of Groundwater, Joseph Byra

Theses

Currently available computer programs that model groundwater flow are inherently limited in their capabilities, in one way or another. Additionally, many of these computer programs are relatively inaccessible to the general user because they operate off of mainframe computers and sophisticated plotters. As a result, a simple to use computer program called 2DFLOW has been modified so it can be run on a personal IBM compatible computer. It models steady-state fluid flow through saturated porous media. In addition, a postprocessor called 2DPLOT has been developed. The postprocessor generates the equipotential contours and the flux vectors that describe the physics of …

Digital Correlators For Spread Spectrum Communications, Raymond B. Chadwick

Theses

The design and application, in spread spectrum communications, of a digital correlator implemented in a Xilinx Field Programmable Gate Array is presented. Spread spectrum communications, correlators and Xilinx Field Programmable Gate Arrays are first introduced. A digital correlator is designed and implemented in a Xilinx Field Programmable Gate Array. Cascading correlators to increase the correlation dimensions is next explored. The maximum operating frequency of the digital correlator is calculated and simulated to be 40 Mhz; a significant speed improvement over commercially available correlators such as those from TRW.
