Application of the continuous time study methodology as developed in this research was restricted to the observation of entree cooks in a 408 bed non-profit university hospital. Observation of work function activities during the first week of a four week cycle menu for three consecutive cycles was classified under three major categories: …
Erasure Of Sediment Surface Features By Mellita Quinquiesperforata (Leske), Walter Richard Boehmer
Erasure Of Sediment Surface Features By Mellita Quinquiesperforata (Leske), Walter Richard Boehmer
OES Theses and Dissertations
Erasure of sediment surface features by individuals of the species, Mellita guinguiesperforata, observed in this study suggests that all members of the sub-order, Scutellina, are able to erase sediment surface features. Sweep time, the time needed to erase the surface features of an area, depends on the population density, individual size, and speed of movement of the sand dollars. Assuming their pattern of movement as random, the following equation can be used to determine sand dollar sweep time,
T - 3.2 N-0.76 (W / S) (A/ W2 )1.21
where T is sweep time, N is the …

The Enzymatic Oxidation Of Aldehydes By Xanthine Oxidase, Duane Beal Gregory
The Enzymatic Oxidation Of Aldehydes By Xanthine Oxidase, Duane Beal Gregory
All Master's Theses
As early as sixty years ago, the existence of an enzyme from mammalian tissues which catalyzed the oxidation of xanthine and hypoxanthine was recognized. The name given the enzyme was derived from its earliest recognized action, hence xanthine oxidase. Although little is known about the biological functions of the enzyme, the high affinity shown for xanthine and hypoxanthine may indicate that these are the most significant substrates biologically.
An In Vivo Perfusion Apparatus For Studies On Gingival Disease In The Albino Rat : Assessment By A Perfusion Of The Enzymes Collagenase And Hyaluronidase, James A. Smith
Loma Linda University Electronic Theses, Dissertations & Projects
This thesis describes an in vivo perfusion apparatus which can continuously deliver controlled quantities of solutions to localized, contralateral intraoral areas in albino rats. Three animals were per fused on the experimental area (the mesial sulcular area of the maxillary first molar) on one side with tap water and Trypan blue. Localization of the solution delivered and minimal histological changes due to the presence of the apparatus was demonstrated on these animals. Solutions of .5%, 1%, and 2% hyaluronidase and collagenase were perfused on the experimental areas of nine animals. When both enzymes were used, hyaluronidase always preceded collagenase in …

Drift Of Oligophlebodes Sigma And Baetis Bicaudatus In A Mountain Stream, William Dean Pearson
Drift Of Oligophlebodes Sigma And Baetis Bicaudatus In A Mountain Stream, William Dean Pearson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The objective of this study was to clarify the relationships between drift rates, population density, production rates, key environmental factors, and movements of adults within two populations of stream insects (a caddisfly--Oligophlebodes sigma and a mayfly--Baetis bicaudatus).
Samples of benthic invertebrates (424 total) were collected every 28 days at four stations on Temple Fork of the Logan River, Utah, from October, 1967 to September, 1969. Samples of drift invertebrates (181 total) were collected every 14 days at three stations on Temple Fork during the same period. During summer months (June-September) a day and a night drift sample …
Evaluation Of Molting Areas Of Great Basin Canada Geese, Paul D. Arneson
Evaluation Of Molting Areas Of Great Basin Canada Geese, Paul D. Arneson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Environmental factors at Neponset and Woodruff Narrows reservoirs were evaluated to determine their effects on molting Canada geese. More geese utilized Woodruff Narrows. Geese apparently favored the larger expanse of open water and adequate food supply.
Most of the molting geese were from the Bear River drainage. Some geese came from scattered areas in Utah, Idaho, Wyoming, and Montana. After molting, the geese flew to migration staging areas in southeastern Idaho before migrating to wintering areas in southern California and Arizona.
Females outnumbered males by 6 percent. The mean annual mortality rate for adult geese was 42 percent. Recovery rates …
A Study To Demonstrate The Immediate Destination Of An Embolus Formed In The Lumen Of A Peripheral Venous Catheter, Rosemarie Morikone Emori
A Study To Demonstrate The Immediate Destination Of An Embolus Formed In The Lumen Of A Peripheral Venous Catheter, Rosemarie Morikone Emori
Loma Linda University Electronic Theses, Dissertations & Projects
This study was designed to show the immediate destination of an embolus formed in the lumen of an intravenous catheter placed in a peripheral vessel. The hypothesis stated that clots injected into a peripheral vessel will lodge in the lungs. A subhypothesis was that the clot may lodge anywhere along the circulatory pathway.
Indications of need for the study as shown by the review of literature were the following: (1) the complications resulting from the frequent use of intravenous polyethylene catheters, (2) experimental studies that showed that clots were formed around intravenous catheters, (3) the evidence that intravenous catheters predispose …

The Pharmacology Of Rodenticides, S. A. Peoples
The Pharmacology Of Rodenticides, S. A. Peoples
Vertebrate Pest Conference Proceedings: 4th (1970)
The compounds used as rodenticides are tremendously varied in their chemical structure and mechanism of action. With a few exceptions, these agents are generally poisonous to all animals, including man, and a great deal of study has been directed to their toxicity in animals other than rodents. However, the development of new compounds as Norbormide and certain antifertility drugs which are highly selective in their action may justify the hope that the ideal rodenticide free of secondary toxic hazards will soon be available. Until this happy announcement is made, a review of the pharmacology of the older compounds is in …

Algal Growth And Decomposition: Effects On Water Quality, Edward G. Foree, John S. Tapp Jr.
Algal Growth And Decomposition: Effects On Water Quality, Edward G. Foree, John S. Tapp Jr.
KWRRI Research Reports
The chemical composition of algae grown in batch culture depends mainly on environmental conditions, nutrient availability, presence of predators, cell age, and species. The effects of nutrient availability and cell age on the composition of three unialgal cultures (algae + bacteria) and one hetergeneous culture (algae + bacteria + microscopic animals) were evaluated. The cultures were grown in batch culture under both nutrient-abundant and nutrient deficient conditions and the changes in compositions were observed. Luxurious uptake where nutrients are incorporated into cellular protoplasm at levels greater than those necessary for growth, and super-luxurious uptake, where some nutrients are stored rather …

Asymptotic Evaluation Of Wkb Matrix Elements. Ii. Use Of Langer's Uniform Asymptotic Wavefunctions, Wesley D. Smith, Russell T. Pack
Asymptotic Evaluation Of Wkb Matrix Elements. Ii. Use Of Langer's Uniform Asymptotic Wavefunctions, Wesley D. Smith, Russell T. Pack
Faculty Publications
An improvement in a previous procedure for the analytic asymptotic evaluation of integrals arising in the quantum-mechanical theory of inelastic molecular collisions is presented. The integrals are evaluated using Langer's uniform asymptotic wavefunctions and the higher-order saddle-point or steepest-descents method. It is found that the Langer functions give no better results than WKB functions, but the higher-order steepest-descents corrections produce a marked improvement. The result is a simple method for evaluating a large class of integrals with an error of 0.1%-2.1%.
A New Tribe Of Saber-Toothed Cats (Barbourofelini) From The Pliocene Of North America, C. Bertrand Schultz, Marian R. Schultz, Larry D. Martin
A New Tribe Of Saber-Toothed Cats (Barbourofelini) From The Pliocene Of North America, C. Bertrand Schultz, Marian R. Schultz, Larry D. Martin
Bulletin of the University of Nebraska State Museum
A new genus of Pliocene Saber-toothed felid, Barbourofelis, is proposed and two new species B. fricki and B. morrisi are described. These two forms and other described material represent an unusual lineage of felids with long sabers, shortened crania, and massive postorbital bars. The tribal name Barbourofelini is proposed for this lineage which is presently known in North America from deposits ranging in age from Clarendonian through Kimballian. The Barbourofelini apparently migrated from Eurasia to North America in the Late Miocene or Early Pliocene. Sansanosmilus of the French Vindobonian appears to represent the ancestral stock of these cats. The …

Reducing Evaporation From Farm Dams : A Progress Report December 1969, I A F Laing
Reducing Evaporation From Farm Dams : A Progress Report December 1969, I A F Laing
Journal of the Department of Agriculture, Western Australia, Series 4
IN most seasons in the Western Australian Wheatbelt evaporation reduction techniques rate a low priority due to either the expense or the relative inefficiency of the techniques.
It is generally agreed that a similar investment in deepening or enlarging existing dams, or making new dams larger from the outset, is likely to be more profitable.
Superphosphate Deficiency Raises Pasture Oestrogens, H G. Neil, T. Marshall
Superphosphate Deficiency Raises Pasture Oestrogens, H G. Neil, T. Marshall
Journal of the Department of Agriculture, Western Australia, Series 4
A recent field experiment on established pastures at Esperance Downs Research Station has demonstrated a relationship between superphosphate application, pasture oestrogens and oestrogenic response in sheep.
Results of the experiment indicate that on phosphate deficient soils carrying oestrogenic clovers, the levels of oestrogenic materials in the pasture are increased if superphosphate applications are below those recommended for healthy pasture growth.
Copper Requirements For The South-Eastern Wheatbelt, D J. Gilbey, K. D. Greathead, J. W. Gartrell
Copper Requirements For The South-Eastern Wheatbelt, D J. Gilbey, K. D. Greathead, J. W. Gartrell
Journal of the Department of Agriculture, Western Australia, Series 4
FARM experience and the results of five years intensive research have shown copper deficiency to be widespread in the south-eastern wheatbelt.
On many areas of the south-eastern wheatbelt, copper deficiency is likely to restrict wheat yields.
