Transient Convective Heat Transfer Coefficient For Injection Into Rigid Vessel, James Edward Steiger

Theses and Dissertations

The purpose of this study was to develop and demonstrate a method for experimentally determining the convective heat transfer in a rigid vessel while air was being injected. The heat transfer took place between the air in the pressurized vessel and the surrounding walls which were maintained at a temperature of 32 F. with a circulating ice water bath. The study considers the effects of injection geometry and injection flow rate on the heat transfer process. The problem of heat transfer after injection has been considered by Means (1), and was responsible for establishing this study. The experimental technique used …

Conduction Error In Thermocouples Embedded In Low Conductivity Material, Tumkur G. Nagaraju

Theses and Dissertations

Thermocouples are generally used as devices to determine the internal temperature of any material. The purpose of the temperature measuring device is to measure the temperature which would exist at some known location if the device were not present. The thermocouples are embedded in the material in order to study the temperature-time history of the point of location. The presence of the thermocouple induces error in the temperature measured. This error becomes significant if heat is conducted into or away from the point of measurement by the sensor itself, or if the sensor insulates the point. This would result from …

An Ecological Life History Of Tall Bluebell In Utah, Verl B. Matthews

Theses and Dissertations

The ecological life history of tall bluebell, Mertensia arizonica Green var. leonardi (Rydb.) Johnston (M. leonardi Rydb.), was investigated during 1963 and 1964. Summer field studies were conducted on the Mud Creek Sleep Allotment of the Uinta National Forest, Wasatch County, Utah. Laboratory and herbarium studies were carried out at Brigham Young University. Specific objectives were to investigate seed germination, seedling development, root system, phenology, palatability, and describe the physical site factors where bluebell occurred. A study of this species was necessary because much of the herbage produced in certain areas of aspen range is not utilized. This condition occurs …

Characterization Of A Soluble Form Of Structural Protein From Neurospora Crassa, Clarence Denis Perterson

Theses and Dissertations

The study of membrane assembly has, until now, consisted of fractionating a membrane into its components or of assembling model membranes from non-physiological components. A native precursor to membranes was obtained as a quasi-crystalline material. It was the purpose of this work to develop the appropriate techniques for characterizing the material as well as to carry out the characterization. The results of the characterization indicate the quasi-crystalline material contains a single protein, structural protein. This protein is in two forms which may reflect two sequential steps in membrane assembly. One form is solubilized in 2-chloroethanol and isolated by gel filtration. …

A Taxonomic Revision Of The Weevil Genus Tychius Germar In America North Of Mexico (Coleoptera: Curculionidae), Wayne E. Clark

Brigham Young University Science Bulletin, Biological Series

A study of morphological characters of 4,000 adult weevils used in preparing a key and descriptions indicates there are fifteen North American species in the genus Tychius Germar. Adults occur on plants in the genera Astragalus, Baptisia, Hedysarum, Lotus, Lupinus, and Oxytropis.

The genus is divided into two species groups. The T. sordidus group appears to have representatives in the Old World fauna, but the T. semisquamosus group is probably native to North America. New names, Tychius caesius, and T. hirsutus are proposed for T. armatus Green, 1920 (not Tournier, 1873), and T. hirtellus LeConte, 1876 (not Tournier, 1873) respectively. …

Notes On Eriogonum - Vi : A Revision Of The Eriogonum Microthecum Complex (Polygonaceae), James L. Reveal

Brigham Young University Science Bulletin, Biological Series

This revision discusses seven closely related species of Eriogonum (Polygonaceae) found in the western United States of North America. One of the two major species, E. microthecum, is composed of nine varieties which range over a wide area of the Far West. The other major species, E. effusum, is found over a more restrictive geographical range mainly east of the Continental Divide. The remaining five species are primarily restricted to the Colorado-Green river drainage basin of Utah, Colorado, New Mexico, and northern Arizona. Together these entities form the core of a group of plants known as Section Corymbosa. …

A Taxonomic Study Of Crotaphytus Collaris Between The Rio Grande And Colorado Rivers, William Ingram Iii, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

Little work has been done previously on the taxonomy of Crotaphytus collaris baileyi. This and the demonstration by Fitch and Tanner that C. c. baileyi is a heterogeneous grouping prompted the present study. Only the populations of the type material, the Upper Colorado River Basin, and the Chihuahuan Desert were studied. Multivariate, variance, canonical and discriminant analyses of external characters were performed, and pattern-coloration characters were examined on living specimens.

The results of the analyses show significance between all three populations. The discriminant functions distinguished between the populations with 80% reliability and patternal characters were discriminatory with near 100% reliability. …
