Recent overseas work and local industry developments indicate that the calcium content of feed for laying hens in Western Australia should be increased to achieve satisfactory egg shell strength.

Age, temperature and breeding are other important influences on egg shell quality.

A Preliminary Study On The Effects Of Organic Pollution Of Banners Corner Cave, Virginia, John R. Holsinger

International Journal of Speleology

Four pools were observed in Banners Corner Cave, Russell County, Virginia, over a 28 month period from November 1961 to February 1964. Three of these pools were visibly polluted with sewage which had seeped into the cave from septic tanks located on the hill above. All four of these pools, at one time or another during the study, contained large populations of planarians, Phagocata subterranea Hyman and isopods, Asellus recurvatus Steeves. Physicochemical and microbiological analyses of the pool waters indicated that oxygen tension is a low as 2.8 mg./l. in one pool and that coliforms and other forms of bacteria …

Algological Studies In The Cave Of Mátyás Mount, Budapest, Hungary, Lajos Hajdu

International Journal of Speleology

Experiments were designed to test the ability of the aphotic speleoenvironment to support algal growth. The first series contained gelatin cultures of Scenedesmus placed in the cave at different localities in order to establish whether or not the microhabitats have any particular effect on the multiplication of the algae. No differences were found in the cultures after a three month incubation period in the cave, which could be traced to influences of microenvironmental conditions. Chlorella cultures in sterile Knop’s solution showed measurable growth in the cave whereas if the cultures were installed into sterilized cave water or were shielded by …

The affected parts become dry and brittle and may break away from the remaining green areas.

Cenozoic And Recent Lunulitiform Bryozoans Of The Gulf And Atlantic Coasts, Ronald Greeley

Doctoral Dissertations

"Free, cup-shaped colonies of cheilostomatous bryozoans, equipped with vibracula, are termed lunulitiform bryozoans. This group is found in sandy and calcareous Cenozoic deposits of the Gulf and Atlantic Coastal Plains. Cupuliform bryozoans are taxonomically distinct from, but in many ways similar to, lunulitiform bryozoans; the two groups are frequently found together.

Known lunulitiform genera of the Gulf and Atlantic Coastal Plains are diagnosed and their species described: Lunulites Lamarck, fifteen species, one new; Oligotresium Gabb and Horn, six species, two new; Discoporella d'Orbigny, two species; Cupuladria Canu and Bassler, two species; Selenaria Busk, one species; Otionella Canu and Bassler, four …

Morbidity, Growth And Development Of Prematurely-Born Twins In Early Childhood, Lynelle King

Loma Linda University Electronic Theses, Dissertations & Projects

This study was concerned with the problem of determining the effect of twinship on the prematurely-born twin's growth and physical and emotional morbidity during early childhood. The immediate purposes of the study were to compare prematurely-born twins with prematurely-born singletons regarding their incidence and types of physical and emotional morbidity, and their growth during early childhood. It was hypothesized that prematurely-born twins have slower growth and more physical and emotional morbidity than prematurely born singletons. The descriptive survey method was used. From children cared for at a selected premature clinic, nineteen twins were matched with nineteen singletons for: race, sex, …

The Role Of Thiamine Pyrophosphate In Regulating The Level Of Gamma-Aminobutyric Acid In The Central Nervous System, Bryant L. Adams

Theses and Dissertations

The level of gamma-aminobutyric acid in the brains of white rats suffering from thiamine deficiency symptoms resulting from pyrithiamine or oxythiamine antagonism of thiamine or from thiamine deprivation was measured. The level of this amino acid was 17.5% lower in the brains of pyrithiamine-treated rats and 20.0% lower in the brains of thiamine-deprived rats than in the control rats. Daily injections of ten times the required amounts of vitamin B6 in rats treated with pyrithiamine or oxythiamine or by thiamine deprivation had no effect on the level of brain gamma-aminobutyric acid or on the psiological behavior of these rats. The …

Studies Of Rat Brain Thiamine Pyrophosphokinase, Lavell Rolfson Johnson

Theses and Dissertations

The enzyme ATP:thiamine pyrophosphotransferase (thiamine pyrophosphokinaseJ was purified from acetone powders which were prepared from rat brains up to the chromatography on alumina C_γ step by a modified procedure that Mano (Y. Mano, J. Biochem., 42, 283 (1960)] developed for the purification of the rat liver thiamine pyrophosphokinase. The enzyme was purified 12 fold over that in the original extract of the acetone powder. A spectrophotometric assay for the brain thiamine pyrophosphokinase was developed utilizing brewer's yeast apotransketolase. The transketolase assay was able to detect less than 10^-11 moles of thiamine diphosphate, which was synthesized by the kinase, in the …

Helianthus Annuus - The Separation And Identification Of A New Fatty Acid, Donald C. Gruber

Masters Theses

Introduction

The term "fatty acids" was first applied principally to saturated, monobasic carboxylic acids and especially to long chain acids derived from animal and vegetable oils. As time passed and the knowledge of natural fats increased, polyunsaturated, hydroxy, keto and branched chain acids were also found as constituents of these fats and oils and these also came under the heading of fatty acids. Even acids containing alicyclic substituents were found.

More recently the term 11 fatty acid" has been applied to include saturated and unsaturated monobasic carboxylic acids and several other series of substituted acids having carbon skeletons similar to …

The Extent To Which Patients Follow Their Low-Cholesterol Diets, Beverly Jo Peterson

Loma Linda University Electronic Theses, Dissertations & Projects

This exploratory study was conducted to discover to what extent patients follow their low-cholesterol diets. If they did not, the reasons were investigated. It was hoped that the findings would aid in defining areas of instruction which need greater emphasis when patients receive instruction concerning a low-cholesterol diet.

An interview guide was used as a data gathering tool. The dietitians at one private teaching hospital recorded all dietary prescriptions sent to them during the specified period and ten physicians were contacted for permission to include their patients in the study. The patients were then contacted by telephone and the interviews …

Preliminary Note On The Algae Of Crystal Cave, Kentucky, J. P. Nagy

International Journal of Speleology

Collections of a preliminary type carried out in Crystal Cave, Kentucky, resulted in the identification of seven algal taxa. A Chamaesiphon (Dermocarpales) and an Asterocytis (Bangioidea) are reported for the first time from a speleo-environment. As no correlation could be found among the algae occurring in Crystal Cave and those of nearby Mammoth Cave the conclusion is reached that the cave algal floras do not originate from the algal vegetation of the surface but may have gotten into the caves at the time of the latter’s formation.

Algological Investigations In Mammoth Cave, Kentucky, H. J. Jones

International Journal of Speleology

Algological investigations carried out in the Mammoth Cave, Kentucky, revealed the presence of twenty-seven taxa representing all divisions of the Algae except the Pyrrhophyta and Phaeophyta; diatoms although observed in the samples were not dealt with in the present paper. One species, Oscillitoria clausiana spec. nov. and a form Lyngbya pusilla fa. tenuior fa. nov., both belonging to the Cyanophyta are new to science. In addition, several other rare and interesting algae were found. A comparison is made between the algal flora of the Mammoth Cave and algae found in several European caves. The ecology of the cavernicole algae is …

Diatoms From Mammoth Cave, Kentucky, Sam L. Van Landingham

International Journal of Speleology

Samples collected in Mammoth Cave, Kentucky, revealed the presence of a diversified but not too abundant diatom community in the cave. As the material was not subjected to culturing experiments but was investigated immediately after arrival, both in native and permanent preparations, it was possible to: 1. ascertain that the majority of the diatoms contained well developed, apparently healthy and functioning chloroplasts and 2. to get a rough estimate of the actual number of specimens present in a microhabitat. The identifications resulted in the recognition of 16 diatom taxa of which possibly 4 are new to science. Further studies are, …

The Annual Distribution And Stratification Of Phytoplankton At Aurora Lake, Portage County, Ohio, Harold G. Marshall

Biological Sciences Faculty Publications

A 13-month study of a hard-water lake in northeast Ohio has provided a quantitative and qualitative record of the seasonal changes of the phytoplankton. Maximum production occurred during the summer and winter periods. The summer pulse was dominated by the cyanophyte species: Microcystis aeruginosa, Anabaena spiroides, A. circinalis, and Aphanizomenon flosaquae. The dominants of the winter pulse were the diatoms Fragilaria crotomensis and Asterionella formosa, which formed separate peaks under an ice cover in December and January, respectively. The January development extended into March with the highest concentrations for the year Being reached at approximately …

Metabolism Of Thiamine And The Effect Of Some Antagonists, Russel M. Bender

Theses and Dissertations

To investigate the possibility that thiamine has more than one vital role in the mammalian system, it was decided to use the antagonists pyrithiamine and oxythiamine, and to utilize carbon-14 labeled compounds to more effectively study the vitamin and the above-named antagonists. To make it more effective, we felt that perhaps differences between the localization of oxythiamine and pyrithiamine could be detected in the brain. We also considered and tested the possibility that either or both of the antagonists would alter the localization of thiamine. Essentially, two procedures were used in this study. One was a counting method and the …

Falls Sustained By Patients In A Selected Nursing Home, Katty Joy Fenton

Loma Linda University Electronic Theses, Dissertations & Projects

This study was done to learn how the incidence of falls was related to certain, selected factors such as ambulatory state, sex, location of occurrence and time of occurrence in the nursing home chosen for the study and to make recommendations for increasing the safety of nursing home patients.

The descriptive-survey was the method used in the study. The data were made available in the form of 235 incident reports which had been collected over a five-year period in the selected nursing home. There were 213 of these records which described falls of various types so the study was limited …

A Study Of The Effect Of Varying Serum Phenylalanine Levels On Changes In Intelligence Quotient, Darlene Imai Manullang

Loma Linda University Electronic Theses, Dissertations & Projects

Data from thirty medical records of phenylketonuric children under treatment were investigated to determine at which serum phenylalanine level (0-3.9 mg. %, 4-7.9 mg %, 8-11.9 mg. %, greater than 12 mg. %) there would be the greatest increase in intelligence. The children involved in the study were divided into the following groups according to the age dietary treatment was initiated: 0 through 5 months, 6 through 11 months, 12 through 23 months, and over 2 years of age.

Among 6 patients who were placed on the diet during the first 5 months of life, it appears that the optimal …

Molybdenum-L-Histidine Complexes, Jiing-Yun Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

L- Histidine is a very important amino acid and is widely distributed in living systems. In the growth and multiplication of animal cells, it was found that L-histidine is one of the amino acids that must be present. From the kinetic studies of certain enzymes such as chymotrypsin and ribonuclease, it has been proposed that the imidazolyl group of the histidine residue may serve as the basic electron donor, and that the histidine residue in some cases may be the active site of the enzyme. The interactions of L-histidine with heavy metal ions, including Ni (II) (1), Zn (II) (1, …

Correlation Of The Maternal Interest And Attitude Toward Breast Feeding Of Senior Students In A Selected School Of Nursing, Bonnie Boyts Wilkens

Loma Linda University Electronic Theses, Dissertations & Projects

A descriptive survey study was carried out at a selected baccalaureate school of nursing in an effort to find out if the maternal interest of senior students of nursing would affect their attitudes toward breast feeding. It was hypothesized that a student who scored high on maternal interest would have a positive attitude toward breast feeding and conversely a student who scored low on the maternal interest scale would have a negative attitude toward breast feeding. Maternal interest was measured by the use of twelve questions adapted from a questionnaire formulated by D. M. Levy, a prominent psychiatrist. Attitudes towards …

The Reaction Of Hospitalized Children To Food, Lois Masat Magnussen

Loma Linda University Electronic Theses, Dissertations & Projects

Hospital personnel are becoming more aware of the fact that hospitalization is traumatic to the emotional life of the young child. Since eating habits and emotions are so closely allied, it is probable that the young child's eating pattern will be affected during hospitalization. The purpose of this study was to determine the reaction of children between the ages of one through four to food during the first three days of hospitalization at the White Memorial Hospital. The method chosen to obtain this information was the descriptive survey. The tools used were a checklist for the researcher to record her …

A Modified Procedure For The Quantitative Determination Of Fluoride And The Application Of This Procedure To A Fluoride Balance Study In Children, Beatrice Shuang Wu

Masters Theses

Introduction

This research problem was done in connection with the fluoride balance studies on twelve children at Plymouth State Home. The retention balance studies of fluoride by children can be studied indirectly by measuring the amounts of fluoride excreted in the urine and feces after administration of the fluoride in water or in vitamins as sodium fluoride. The fluoride balance study was repeated, because in the previous study (19), there were no samples collected for a base day in which the fluoride was not given. The previous data also indicated that fluoride retention was merely a function of the interval …
