Productivity Of The Roll-Streak Method To Perform Anaerobic Bacteriology In The Routine Clinical Laboratory, Thomas R. Neblett
Productivity Of The Roll-Streak Method To Perform Anaerobic Bacteriology In The Routine Clinical Laboratory, Thomas R. Neblett
Henry Ford Hospital Medical Journal
Data presented are derived from one year of performing routine clinical anaerobic bacteriology by the roll-streak tube method. 826 specimens from 1508 (54.8%) contained anaerobes. 162 specimens were polymicrobic (19.6%) and contained 528 strains of a total of 1051 isolated (50.2 %). 479 blood specimens contained 525 strains of anaerobes. Propionibacterium, considered a contaminant, occurred 209/210 times in blood as the sole isolate. Bacteroides occurred alone or polymicrobically 308 times and comprised 54.7% of the blood isolates and 32.5% of the total anaerobic genera isolated. Clostridium, Peptococcus and Fusobacterium were the next most frequently occurring anaerobes. The roll-streak method is …
Effects Of Cariogenic And Noncariogenic Diets On The Concentration Of The Parotid Hormone Releasing Factor In Rat Hypothalami, Melva Joan Brown
Effects Of Cariogenic And Noncariogenic Diets On The Concentration Of The Parotid Hormone Releasing Factor In Rat Hypothalami, Melva Joan Brown
Loma Linda University Electronic Theses, Dissertations & Projects
Hypothalamic and cortical extracts from various cariogenically grouped rats which had been maintained on either a Purina diet or a high sucrose diet (HSD) for three months were infused intravenously into 28 days old rats to determine if there was a titer of parotid hormone releasing factor (PRF) capable of facilitating fluid movement (FM) in the teeth. The hypothalamic and cortical extracts obtained from Purina-fed rats with 0-caries and the hypothalamic extracts from BSD-fed rats conclusively demonstrated FM stimulatory ability. Other Purina-fed groups were essentially biologically ineffective, however, extracts from HSD-fed caries groups including scores 11-40 demonstrated extremely potent FM …

Faculty Honor Lectures
Throughout most of this century Utah State University has been developing its competence to a position of eminence in the science and art of irrigation and related fields of agriculture and engineering. It has accepted the responsibility to train local as well as international students and through a contract with USAID, conduct research in developing countries. Thus, we in irrigation find ourselves an integral part of the U.S. strategy to assist in closing the gap in development and hopefully winning the battle against world famine. To many this seems hopeless, and it may be, but I have a feeling that …

The Horse Population Of Utah And Its Impact, Scott Stewart Mckendrick
The Horse Population Of Utah And Its Impact, Scott Stewart Mckendrick
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
PART I
The horse numbers of Utah had not been accurately counted since the early 1960's. It was estimated that horse and pony numbers were reaching heights as recorded before the age of tractors and automobiles. Horsemen in Utah were asking for financial assistance for public horse facilities from the Utah legislature. The first part of this study was to survey the horse population to determine an accurate count of Utah horses.
PART II
In order to be satisfied that the horse industry deserved the spending of public funds, it was necessary to know the economic contribution of the horse …

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
In the highly competitive cattle market of today a scientific method, by which a rancher can base a judgement, moderated by experience as to which animals are to be kept, as proven by superior performance, can be a valuable asset.
This record performance testing system was designed to demonstrate the value of adequately kept records. Its purpose is to help ranchers develop records of herd performance, inventory, and improve management practices by more informed decisions. The system, through its representative, provides a means by which ranchers can obtain information on new ideas in animal production, health, sanitation, nutrition, management practices, …
Quantitation Of Aliphatic Aldehydes In Rancid Turkey Meat Using A Substituted Hydrazone, Stanley J. Andrews
Quantitation Of Aliphatic Aldehydes In Rancid Turkey Meat Using A Substituted Hydrazone, Stanley J. Andrews
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Many objective chemical tests have attempted to correlate with organoleptic evaluation of oxidative rancidity. Major chemical tests used to detect oxidative rancidity of lipids measure nonvolatile high molecular weight carbonylic substances which make no considerable contribution to rancid flavors. High molecular weight carbonyls are present at much greater concentrations than volatile low molecular weight carbonyls. Peroxides and other unknown substances also react in these chemical tests to give at best an empirical evaluation. A 3-methyl-2-benzothiazolinone hydrazone chemical test is proposed which corrected some deficiencies of earlier procedures, and was correlated with organoleptic evaluation of rancid turkey samples. The proposed test …
Some Effects Of Mechanical Deboning On The Composition And The Bioavailability Of Protein And Iron In Turkey Frame Meat, Lowell C. Allred
Some Effects Of Mechanical Deboning On The Composition And The Bioavailability Of Protein And Iron In Turkey Frame Meat, Lowell C. Allred
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Meat was obtained from a single daily lot of turkey frames by mechanically deboning with a Beehive AU 4171 deboner and by hand deboning. The meat was analyzed for protein, fat, moisture, ash, iron, calcium, and 19 amino acids. Mechanically deboned turkey had 68 percent more ash, 74 percent more iron, and nine times more calcium than the hand deboned turkey meat. Other constituents were about equal in the two products. Protein bioavailability tests, including protein efficiency ratio, biological value, net protein utilization, and nitrogen efficiency for growth, did not reveal significant differences between mechanically deboned and hand deboned turkey. …

A Longitudinal Study, Part Iii: The Relationship Of Weight, Health Status, Diet And Anxiety To Serum Cholesterol Levels In Adults, Kristine S. Saunders
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Over an 18-year period, beginning in 1955, a group of subjects has been studied six times to determine if any relationship exists among serum cholesterol levels, body weight, health status, diet quality and stress or anxiety. For the first four test periods, extending through ages 7 to 16 years, there were 321 subjects. Later, in 1968, 86 of the original 321 subjects, now aged 19-22 years, were able to participate in a follow-up study. The 1974 study was able to involve 30 of the original 321 subjects now aged 26-29 years. Findings show that from approximately the fifteenth year onward …

Heat Stability Of Residual Milk Clotting Enzymes In Cheese Whey, James Winter Duersch
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Eliminating calcium chloride and replacing whole casein with k-casein eliminated clouding and sharpened diffusion boundaries in casein-agar gels used for the estimation of residual milk clotting enzymes in curd and whey. It also eliminated the need for a highly purified calcium-free agar. The substrate contained .54 percent k-casein, 3.6 percent sodium acetate, .73 percent bacto-agar and 95.13 percent water. The pH was adjusted to 5.9 with .1N hydrochloric acid.
Proteases derived from Mucor pusillus var Lindt, Mucor Miehei and Endothia parasitica, as well as rennet, procine and bovine pepsins were used at recommended levels to set milk for …

The Role Of Zinc In Insulin Metabolism In The Pancreas Of The Rat, Chih-Chi Liaw
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A series of in vitro trials have been conducted to determine what relationship exists between zinc and the insulin mechanism.
There were no significant differences of the zinc contents in total pancreases excised from the rats thirty minutes after the intraperitoneal glucose dose or from the non-dosed controls. When pancreases were cut into three pieces, and treated in three ways: Incubated without glucose (IWG) followed by isolation of the islets; incubated with glucose (IWG) followed by isolation of the islets; islets were isolated, then incubated with glucose (IWG). The zinc content in the islets was significantly higher (p < 0.01) in the first group than the others.
The insulin …

Productivity Of Two Utah Deer Herds As Related To Nutrition, Clarence Leon Pack
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A study of mule deer occupying deer management units 53 and 54 in south central Utah was conducted from August, 1971 to May, 1974 to determine food habits, caloric requirements, dietary nutritional levels, and productivity. Transects, fecal analyses, weight data, classification counts, and forage analyses were used to accomplish these objectives.
Food habits of deer on the two units were similar, except for higher use of scrub oak on unit 53 and higher use of snowberry on unit 54.
Deer on unit 54 were significantly larger than those on unit 53. Thus, their caloric requirements also were significantly higher.
Deer …

Effects Of Forced Exercise On Fertility, Parturition, Mammary Edema, Feed Consumption, And Milk Production In Two-Year-Old Holstein Dairy Heifers, Brent O. Barker
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Forty-two springer Holstein heifers were grouped in threes by sire, body weight, and due date. One of each group served as a control (no exercise). One of each group was exercised at 5.5 kilometers per hour for 1.6 kilometers per day, 5 days per week beginning 4 weeks before expected calving date . The third member of each group was exercised the same as the second member, but exercise was continued for 10 days after calving. Exercise was in a circular lane with a motor driven gate. Prepartum exercise increased ease of parturition and reduced the length of time from …

Feeding Behavior Of Pen Reared Mule Deer Under Winter Range Conditions, Michael A. Smith
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study examined the feeding responses of mule deer to a system of spring livestock grazing. The specific purposes were 1) to determine botanical composition of diets selected by mule deer on a winter range subjected to previous spring grazing by sheep compared to one with no sheep grazing and 2) to develop a basis for predicting selection of individual plants by deer, based on physical characteristics of the plants and the species and physical proximity of associated plants.
The study was conducted within the framework of a completely randomized experimental design with two treatments. Variables controlled for each unit …
Forage Selection And Nutrition Of Sheep And Goats Grazing In The Tunisian Pre-Sahara, Rudolfo Ricardo Griego
Forage Selection And Nutrition Of Sheep And Goats Grazing In The Tunisian Pre-Sahara, Rudolfo Ricardo Griego
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Nomadic pastoralism has been the traditional method of utilizing grazing resources in arid and semi-arid regions of Africa. However, increased sedentarization accompanied by growing human and animal populations during the past two decades is thought to be accelerating the desertification process, or desert expansion. The specific interactions of the grazing animal with this process has been speculated upon but not studied in detail. A comparative study was initiated during the spring grazing season of 1974 to determine sheep and goat nutritional and production responses, as well as patterns of vegetative selection and utilization under the pastoral system currently employed in …

Selected Vitamin Status Of Elderly People In Southern Utah Measured Biochemically And Dietarily, And Correlated To Their Perceived Status, Karen Sims Faddis
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The purpose of this study was to analyze the diets of elderly people in southern Utah. Three types of information were used in the analysis: biochemical, dietary, and the subject's analysis of his diet. Four vitamins were studied: vitamin A, ascorbic acid, thiamin, and riboflavin.
Dietary data was obtained on the four vitamins and compared by sex and by age. Thiamin and riboflavin dietary levels were evaluated using the Index of Nutritional Quality (INQ), to determine the quality of the diet according to the total calories consumed. Seasonal differences between fall and spring data were evaluated.
Plasma vitamin A, plasma …
Nitrogen Cycling In A Microcosm Simulation Of The Northern Arm Of The Great Salt Lake, John C. Stube
Nitrogen Cycling In A Microcosm Simulation Of The Northern Arm Of The Great Salt Lake, John C. Stube
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Nitrogen cycling was studied in the hypersaline northern arm of the Great Salt Lake (332,480 mg/l total dissolved solids) using a sediment-water microcosm simulation of that system. The study demonstrated that nitrate, ammonia, and urea were not stimulating to the halophilic bacteria in the microcosm. The bacteria were simulated only indirectly simulated bacterial growth. In addition, no nitrification could be demonstrated during the study.
Weekly analyses of water samples from the north arm of the lake itself showed that nitrate and nitrite were absent, leaving ammonia as the only significant form of inorganic nitrogen in the northern lake basin. Other …
Insect Consumption Of Seeded Rangeland Herbage In A Selected Area Of Diamond Fork Canyon, Utah County, Utah, Diane M. Bowers
Insect Consumption Of Seeded Rangeland Herbage In A Selected Area Of Diamond Fork Canyon, Utah County, Utah, Diane M. Bowers
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study compares insect and cattle consumption of crested wheatgrass (Agropycon spp.) on a site in Sterling Ranch, Utah County, Utah. The hypothesis tested is that insect consumption in general, and specifically consumption by Labops hesperius Uhler, significantly reduces total available cattle forage.
Labops and grasshoppers were probably the major cause of secondary damage at the study site, while the impact of thrips is unknown. A detrimental impact on range was suggested by the data, as insects consumed forage equivalent to 2.8 animal units per month, while cattle consumed forage equivalent to 2.1 animal units per month at the …

LSU Historical Dissertations and Theses
Seasonal changes in the body component indexes of Littorina irrorata were studied for a two year period. Biochemical constituents (protein, carbohydrates, and lipids) in the soft body components were analyzed for one year. Body component indexes cycled seasonally. Shell index changes may be due to the seasonal changes in the total of other indexes. All soft body components, except the foot, exhibited a seasonal cycle which was correlated with the reproductive cycle. Female Littorina irrorata appeared to exhibit a bimodal pattern of capsule deposition with the two peaks occurring in May and August. Seasonal changes in the biochemical level and …

Ecological Investigations In Cercocarpus Ledifolius Nutt. Communities Of Utah, James Newton Davis
Theses and Dissertations
Cercocarpus ledifolius communities of Utah were sampled to determine which measured environmental characters were influential in determining community structure and dynamics. Nineteen, one-tenth acre stands were sampled by 25 equally spaced .25m2 quadrats. Plant frequency, cover, density, height, diameter, age, elevation, slope and exposure were determined for curl-leaf mahogany within the study area. Soil depth and soil samples were analyzed for texture, pH and soluble salts. Curl-leaf mahogany is found almost entirely on arid rocky slopes, canyon ledges, and plateaus at relatively high elevations on all exposures. The soils were invariably shallow and slightly acidic with sandy loam soils being …

The study area is included in Currituck Bank (North Bank), which extends from the Virginia-North Carolina boundary southward to the town of Nags Head, a distance of about 45 miles (Fig. 1). The bank was originally demarcated by two inlets; Old Currituck Inlet, which was located …
Effect Of Supplemental Food On Population Estimates And Mortality Rates Of Desert Rodents In Utah, J. Steven Thiriot
Effect Of Supplemental Food On Population Estimates And Mortality Rates Of Desert Rodents In Utah, J. Steven Thiriot
Theses and Dissertations
The objective of this research is to assess the effects of various quantities of supplemental food (seed) on population estimates and mortality rates of desert rodents . The supplemental food is meant to stimulate natural vegetational productivity. If food availability significantly affects the population parameters methods of population estimators previously used may be in error. Hopefully this study will aid small mannnal research by designating whether, in part, population estimates and mortality rates are in error because of high vegetational productivity. The hypothesis of this study is that supplemental food in the natural environment decreases population estimates and mortality rates …
