Factors Affecting The B-Vitamin Content Of Cottage Cheese, Gary Dean Reif

Open Access Master's Theses (through 2010)

The purpose of this study was to investigate the vitamin content of Cottage cheese and to study the factors which may alter the content of certain B-vitamins. The specific objectives were as follows:

1. To determine the niacin, B₆, B₁₂ and folic acid content of skimmilk and Cottage cheese and the retention of those vitamins in the curd from the milk.
2. To study the synthesis of niacin, B₆, B₁₂ and folic acid during the 16-hr setting period used in making Cottage cheese, and to determine whether the vitamin synthesis by the starter was partly responsible …

Presettlement Vegetation And Vegetational Change In Three Valleys In Central Utah, Earl M. Christensen, Hyrum B. Johnson

Brigham Young University Science Bulletin, Biological Series

Historical information, survey records, and relict vegetation were used as sources of data for determining the nature of the presettlement vegetation of Pavant, Round, and Juab Valleys in central Utah. The foothills were covered with bunch grasses (principally Agropyron spicatum and Poa secunda), scattered junipers (Juniperus utahensis), and sagebrush (Artemisia tridentate). Western wheatgrass (Agropyron smithii) was common on level areas within the foothills. Below the foothill region on the more gentle slopes and benchlands there was a broad belt dominated by bunch grasses. The grassy area intergraded into a zone dominated by northern …

Second Bibliography And Index For The Philosophy Of Geology, Claude C. Albritton Jr.

Journal of the Graduate Research Center

The body of writings on the philosophy and history of geology has grown in a remarkable way since the end of the Second World War. There is no obvious explanation for this quickening of interest in what are surely the most academic aspects of a science best known for its practical applications. Influences arising both from within and from outside the geological profession have probably been responsible. It is a matter of record that many departments of geology, upon resuming full-time operations after the war, decided not to go on moving in the old curricular ruts. The new courses, even …

Distribution Patterns Of Pocket Gophers In The Hobble Creek Area, Utah County, Elvis J. Holt

Theses and Dissertations

This study was initiated to investigate the distribution patterns of two species of pocket gophers, Thomomys umbrinus albicaudatus Hall and T. talpoides wasatchensis Durrant whose ranges come together in the Hobble Creek area, Utah. The effect of certain ecological factors upon their distribution was determined. The ecological factors included: vegetation and land use, soil, moisture and exposure, hybridization and interspecific competition. From morphological examination no interbreeding was detected even though the breeding seasons of the two species correspond. A limited area was found where the ranges of the two species are in contact. A lack of available moisture was determined …

Sleep Movements In Oxalis, Charles A. Campman

Biology ETDs

This work was done to explore the causes of sleep movements in Oxalis. Several methods were employed to discover the answers to speific questions concerning Oxalis nyctinasty.

The question of the control of Oxalis leaf movement by a typical biological clock and problems of the parameters of photic control are answered with the help of light control chambers and time-lapse photography. An anatomical study of the pulvinus, or motile organ, is described. Physiological studies consisted of tests for the site of activity of light and color of light active, as well as comparisons of the action on pulvini of externally …

Seasonal Population Fluctuations And Natural Control Of The Sweetclover Aphid, G. R. Manglitz, R. E. Hill

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Because the potential of the sweetclover aphid for damaging sweetclover is well documented, yet damage occurs only occasionally under field conditions, it would appear that natural factors which depress midsummer populations are important in preventing greater damage and worthy of detailed study. Thus, this study was begun early in 1959 to investigate the natural factors which generally keep populations of this aphid below levels causing economic damage.

Some Effects Of Photoperiodicity On The Temperatures And Weights Of Bobwhites, Bernard J. Cripps

Masters Theses

Introduction

In recent years there have been a number of studies that have dealt with body temperature and body weight variations in gallinaceous birds under various field or controlled conditions. Wilson (1948) studied the reactions of pullets to different environmental temperatures. In a laboratory experiment Bajpai (1962) observed that a change in the cloacal temperature of adult Rhode Island Red males was effected by manipulating the photo-period. In a report on the sexual maturation of Coturnix quail Wilson et al. (1962) discussed several aspects of variation in body weight, which resulted from changes in photo-period. Hamilton (1957) studied the weights …

An Investigation Of The Influence Of The Suprapharyngeal Ganglia Upon Water Balance And On Osmoregulation In Lumbricus Terrestris, Richard M. Dennany

Masters Theses

Chapter I

Introduction

In the central nervous system of most animals which have been examined some neurons show cytological characteristics of gland cells. These cells are now recognized as a specialized cell type and designated neurosecretory cells.

These neurosecretory cells are capable of elaborating secretory material which is accumulated as granules in the body of the nerve cell and in the axon-endings. They release complex organic substances, neurohormones, which act as hormones and are often liberated into the blood stream (Welsh, 1958). These specialized neurons are capable of receiving impulses from other neurons although their axons do not end in …

Comparative Myology Of The Pectoral Girdle Of Microtus Pennsylvanicus And Pedomys Ochrogaster, Marie Hagerman

Masters Theses

Introduction

The meadow vole Microtus pennsylvanicus (Ord) and the prairie vole, Pedomys ochrogaster (Wagner) are two species of grassland-dwelling, slightly fossorial rodents which are very similar in appearance and general body size and proportions. The objective of this study was to prepare a detailed description of the muscles of the pectoral girdle of M. pennsylvanicus and to compare them to P. ochrogaster. It was hoped that the study might indicate similarities and dissimilarities in the ways in which the two species have adapted to their mode of life and show whether or not they share common adaptations of the pectoral …

Autoradiographic Localization Of Serotonin And 5-Hydroxytryptophan In The Rat Brain, Gordon Keith Matheson

Theses and Dissertations

Serotonin is a normal constituent of the brain and has been claimed to act as a neurohormonal or regulatory agent in nerve transmission. Previous workers have only studied its whole brain or subcellular particulate distribution. Because the brain itself is divided into many distinct ganglia and nuclei, the distribution of serotonin in these sites is considered to be of greater importance than either the whole brain or subcellular distribution. This paper is a study of the distribution of serotonin in particular brain sites in rats with normal and elevated levels of the amine, with and without electroshock treatment. The results …
