A Comparison Of The Vibratory Muscle, Tail Epaxial Muscle, And Body Epaxial Muscle Respiratory Activities In Sistrurus Miliarius, Coluber Constrictor, And Natrix Fasciata, Craig Todd Kerins

Master's Theses

The rattlesnake can be distinguished from other types of snakes by its rattling apparatus. Klauber (1956) describes the rattle as an apparatus consisting of varying numbers of three lobed keratin segments. The segments arc arranged in a string by the loose interlocking of the segment lobes. The rattle is attached to tho. snake by the style, the modified terminal vertebra of the rattlesnake. The style is distally branched, forming a rigid core for the proximal rattle segments. A sound, unique to the rattlesnake, is produced when the segments arc vibrated at great frequencies by the snake's posterior tail musculature (Klauber, …

The Effect Of Estradiol On Protein And Nucleic Acids Of The Liver Of Natrix Fasciata, Alex Jordan

Master's Theses

The effects of estradiol on RNA, DNA, and protein concentrations in the liver of Natrix fasciata (southern banded water snake) were investigated. Nucleic acid and protein concentrations were determined spectrophotometrically and expressed as mg/gm wet weight tissue.

Significant increases in both RNA and protein occured 48 hours after a single injection of estradiol. After 72 hours the mean RNA level in estradiol treated snakes had decreased significantly from the 48 hour level. The mean protein level at 72 hours, although lower than the 48 hour level, did not decrease significantly.

Liver DNA concentrations in experimental and control snakes were the …

Social Structure Of Small Mammal Populations At The National Reactor Testing Station, Idaho, R. Lynn Speth

Theses and Dissertations

This investigation examined the social structure of four species of small mammals (Perognathus parvus (Peale), Reithrodontomys megalotis (Baird), Peromyscus maniculatus (Wagner), and Dipodomys ordi (Woodhouse) at the National Reactor Testing Station (NRTS) in Idaho. An understanding of the social structure provides ecological clues concerning the integration of interactions, reproduction, distributions, densities, and diel activities for not only one animal and species, but for a complex of animals interacting with each other.

Need For Post-High School Technical Training In Ornamental Horticulture In Davis, Salt Lake, And Utah Counties, Paul Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The need for a technician training program in Ornamental Horticulture was studied in Davis, Salt Lake and Utah counties utilizing interviews and mailed survey instruments.

The greatest job increase during the next five years is anticipated for nursery workers, landscape helpers and greenhouse workers. The smallest anticipated increase is for florists, floor foreman and nursery technicians.

Skills requiring the highest degree of competency for workers in ornamental horticulture, according to employers, are retail salesmanship, plant identification and disease and insect control.

Courses receiving the highest rating in an ornamental horticulture technician curriculum, as given by owners and managers and by …

Meteorological Factors Controlling The Emergence Of The Eastern Spadefoot Toad, Scaphiopus Holbrooki Holbrookii Harlan, Larry Judy

Theses, Dissertations and Capstones

Scaphiopus holbrooki holbrookii, the Eastern Spadefoot, can exist in an area for many years before it is detected. Its apparent scarcity can be explained by its secretive, fossorial habitat, protective coloration, and nocturnal behavior. Spadefoots are present at the surface locally in small numbers on any one night. They emerge only when conditions are optimum. One authority has suggested that temperature, moisture, and barometric pressure exert control over emergence.

It was the purpose of this research to discover the most important meterorological parameters and investigate how they control the behavior of Scaphiopus.

Initially the response, emergence to breed was distinguished …

Molecular Transfer Of Acquired Discrimination By Proteinaceous Extract, Robert L. Sayre

Theses, Dissertations and Capstones

Early investigators of the molecular basis of memory suggested a unique function for the nucleic acids in learning and memory, with base changes in RNA being the most popular mechanism in representing memory for experiential events. Subsequent research has led to the hypothesis that RNA is intermediary in the general action of cells, but some researchers continue to think of RNA as providing a unique contribution during learning.

Some Parameters Of The Second-Order Conditioning Of Fear In Rats, Alan Kamil

Papers in Behavior in Biological Sciences

The effects of CS1 duration, partial reinforcement, and trace conditioning on second-order conditioned suppression were investigated, employing 64 rats as Ss. In Experiment 1, the clearest second-order conditioning was obtained when CS1 duration was the same during both the first- and the second-order conditioning phases of the experiment. In Experiment 2, somewhat better second-order conditioning was obtained when first-order conditioning had been under conditions of partial reinforcement, delay CS-US pairing. In neither experiment were CS1 suppression and CS2 suppression during second-order testing well correlated. This aspect of the results raised the question of the influence of nonclassical conditioning factors on …

The Effects Of Estradiol Benzoate On Protein Synthesis By The Isolated Perfused Snake Liver, William Ralph Boone

Master's Theses

The effect s of estradios benzoate on protein synthesis by the isolated perfused liver of Natrix fasciata fasciata (Linnaeus, 1766), the southern banded water snake, were investigated. The incorpora­tion of carbon-14 labeled leucine into plasma protein of the liver perfusate was used as an index of protein synthesis by the perfused liver.

Both control and experimental livers demonstrated incorporation of the labeled leucine into plasma protein. However, estrogen treated livers expressed significantly greater incorporation of the amino acid into plasma protein giving an almost linear response. Total plasma protein levels were also significantly higher in the perfusions involving estrogen treated …

Nutrition During Pregnancy, Lactation And Infancy, Minodokht Froozani

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

In many countries in South and East Asia, most diets are defective in quality, even when there is not a severe shortage of food. They do. not provide an adequate quantity of essential nutrients. One of the most severe deficiencies is in good quality protein. The solution to this problem is to produce and provide the right kinds of foods and to establish national food production policies which should make it possible to plan a better balanced diet based on sound nutritional principles and modern knowledge of nutritional requirements. Some degree of undernutrition, over-nutrition, or malnutrition occurs in most European …

Food And Nutritional Needs Of The World Population By 2000 A. D., Sitaram Shankar Kharbas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations were carried out to project the food needs of the world population by 2000 A. D., and to explore the possibilities of meeting these requirements.

About 70 percent of the world population presently living in developing countries do not get adequate diets, and suffer from many diseases of under-nutrition and malnutrition. They are unable to increase food production themselves. People in the developed nations have enough food and their food production is increasing at a rate faster than the rate of growth of population.

Cultivable land is the main source of food for man. The seas can also be …

Development And Evaluation Of A Waiver Examination For The Introductory Foods Course At Utah State University, Virginia Clark Bragg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A written objective-type waiver examination for the introductory foods course at Utah State University has been developed and evaluated.

Results of the study showed that the examination improved with revision. In addition, it was found that there was a statistically significant relationship between the score students achieved on the waiver examination and the total numerical score representing the final grade in the basic foods course.

There was apparently no significant relationship between the number of years experience students had in food preparation, the type of experience in food preparation, and their performance on the waiver examination. Apparently depth of knowledge …

Consumer Attitudes Affecting The Use Of Fluid Milk Products In Metropolitan Salt Lake City, Wayne N. Monson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A survey of 360 respondents in metropolitan Salt Lake City was made to determine their attitudes about fluid milk products and the affect of these attitudes on consumption levels. The fluid milk products studied were regular whole milk, two percent milk, skim milk, and nonfat dry (powdered) milk.

The respondents had the most positive attitudes about regular whole milk. Their attitudes about the other three products were highest for those which most nearly resembled regular whole milk. The consumption levels of the four products followed the same pattern.

The respondents' attitudes about four attitude parameters affected their consumption levels. Those …

Mature Pine Forests In Duluth Harbor Area, Donald W. Davidson, John B. Bernard

Journal of the Minnesota Academy of Science

Quantitative and qualitative studies have been made on mature pine forests of selected areas on Minnesota Point and Wisconsin Point in the Duluth-Superior Harbor area. The forests were sampled by the point quarters method. The leading dominant in the Minnesota forest was Pinus resinosa, while the leading dominant in the Wisconsin forest was Pinus strobus. Trees up to 173 years of age were found on Minnesota Point, while the maximum age of the trees sampled on Wisconsin Point was 142 years. A total of 87 species of vascular plants were identified in the two areas.

The Isolation And Characterization Of Soluble Brain Proteins, Gudrun Staub Bennett

Student Theses and Dissertations

The experiments described in this thesis were undertaken in order to define and purify proteins that might have a specific function in nerve activity. The studies were limited to rat brain proteins soluble in dilute aqueous buffers at neutral pH. Fractionation procedures for these proteins and two means of identifying individual proteins of interest in the fractions were developed. The soluble proteins were divided into two classes according to their solubility in mildly acidic conditions: the pH 5 soluble and pH 5 insoluble fractions. Two different large anatomical areas of the brain referred to as "cortex" and "brainstem," contained the …
