Compounds In Bovine Urine Which Change In Concentration During The Estrous Cycle: Possible Pheromones, Scott Kay Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the last thirty years it has become increasingly apparent that pheromones play a major role in animal communication. Of economic interest to agriculturalists is the role pheromones play in signaling the state of estrus. The ability to efficiently detect estrus is becoming increasingly important, especially in the management of dairy and beef herds, where artificial insemination is used extensively. The understanding of pheromones may eventually provide a solution to this problem.

The purpose of this study was to identify one or more compounds in the urine of cattle which undergo a change in concentration during the estrous cycle.

'That Place Over There' A Journalistic Look At Latter-Day Corinne, The Last Gentile Railroad Boomtown In The Mormon Lands Of Utah, John W. Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effort here, compiled over a nearly three-year period, is simply to encourage reporters of the mass media, those recorders of instant history on a daily basis, to take the time to put down in print somewhere the memories of old-timers everywhere. While centered in Corinne, Utah, the last rabble-rousing boomtown along the first transcontinental railroad to span the United States, this work is a collection of feature articles, laced with anecdotes and perhaps tall tales, of the type old-timers are eager to tell. It is a renegade mixture of oral and written histories and probably breaks most of the …

Verbal Interactions Among Elementary Students With The Jigsaw Ii Learning Method, Katherine Gilbert

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The cooperative learning method, Jigsaw II, was implemented in a grade four social studies class for the purpose of examining the verbal interactions among students as they learned from each other. Jigsaw II is structured to enhance cooperation because each student has exclusive information that is needed by other group members to do well on a test. It was hypothesized that the more capable students in a heterogeneous learning group would help the less capable ones learn the material. As the lower ability students gained proficiency in teaching their information, the variance in the rates of speaking would be less …

Impact Of Development On Traditional Pastoralism In Somalia, Abdulkadir A. Handulle

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Somali pastoral nomads live in an environmental condition of risk and uncertainty. The scarce and unreliable rainfall is the primary element ·which determines the existence of nomadic pastoralism. The lands devoted to pastoralism in Somalia are those arid and semi-arid areas that could not sustain cropping, so that pastoralism may be considered the only rational utilization of the land resource. Nomads live in an environment where the survival of both animals and plants are constrained by many factors such as droughts. Yet, both nomads and their animals have evolved by learning numerous adaptive strategies to cope with their harsh, …

Within a framework of an overview of the current status and potential of X-ray microscopy, a description is given of the development of the King's College scanning instrument which produced its first images in September, 1986. The instrument was mounted on the newly-built undulator beam line at the UK Science and Engineering Research Council's SRS synchrotron. There are consequently three sites worldwide where high-resolution X-ray microscopes with zone-plate optics are in operation. The other sites are BESSY-Berlin and NSLS-Brookhaven.

Germ Cell-Somatic Cell Relationships: A Comparative Study Of Intercellular Junctions During Spermatogenesis In Selected Non-Mammalian Vertebrates, R. L. Sprando, L. D. Russell

Scanning Microscopy

Specialized germ cell-somatic cell relation-ships were. surveyed in the testis of species representative of four classes of non-mammalian vertebrates. Desmosome-like junctions were present in all classes studied. In the teleost fish studied (bluegill; Lepomis macrochirus) small, infrequent desmosomes, seen between the spherical cyst cells and spermatocytes were characterized by poorly represented subsurface densities. In the bullfrog (Rana catesbeiana), similar desmosome-like junctions were found between cyst cell processes and spermatocytes. Reptilian. (turtle; Pseudameys scripta) desmosome-like Junctions between Sertoli cells and germ cells were heterogeneous and more numerous than those junctions found in fish and amphibians: In general, …

Development Of Ocular Inserts For Cattle, R. T. Greer, J. P. Ryoo

Scanning Microscopy

Ring shaped ocular inserts have been developed to administer a therapeutic level of tylosin tartrate throughout a five day period to treat pinkeye in cattle. The inserts are based on polyvinyl chloride rings which are dip coated with a copolymer containing the antibiotic (tylosin tartrate). Scanning electron microscope (SEM) characterization of surfaces has been of value to evaluate the presence and extent of surface flaws in the hydrogel coating, and to contribute to improvement in fabrication of the rings to insure the establishment of satisfactory seals at joints, uniformity of microporosity and cross sections, and the absence of significant cracking …

A Scanning Electron Microscopy Study Of Human Spleen: Relationship Between The Microcirculation And Functions, Makoto Kashimura, Tsuneo Fujita

Scanning Microscopy

This paper reviews scanning electron microscope (SEM) observation of the circulatory system of the human spleen, based on our findings on freeze-cracked surfaces and vascular casts of the spleen.

Central arteries ran straight in the white pulp without branching out follicular arteries and became penicillar arteries in the red pulp. Some penicillar arteries returned to the marginal zone. Some of their branches ended by opening there, whereas others passed through the marginal zone, entered the white pulp and became follicular arteries. Some of them took the shape of an "arteriolar-capillary bundle". Most of the follicular capillaries ended opening into the …

A Comparative Study On In Vitro Invasion Rates By Melanoma Cells In The Human Amniotic Basement Membrane Model Versus In Vivo Tumor Nodule Formation In C57bl6 Mice, B. Persky, G. W. Chmielewski

Scanning Microscopy

Invasion by murine B16-F10 melanoma cells was studied using the human amniotic basement membrane (HABM) assay. B16-F10 cells were collected after a single passage through the amnion and grown to near confluency. The cycle of plating, passaging, collecting, and culturing B16-F10 cells was repeated five times. The invasion rate for B16-F10 cells remained relatively unchanged after six passages through the amnion. Injection of first-passage B16-F10 cells into C57BL6 mice resulted in 29 lung tumors per animal whereas sixth-passage cells resulted in 300+ lung tumors. While there exists no correlation of the number of cells penetrating the amnion with colonization number, …
