Autonomy And Determination Of Abnormal Growths In The Tumorous Head Strain Of Drosophila Melanogaster, David Joseph Remondini

Biology

The tumorous head (tu-h) strain of Drosophila melanogaster is characterized by variable, amorphous or partly organized growths about the adult head, including the eyes, antennae, and facial regions but excluding the mouthparts. No other regions of the body have been found to be affected. The trait is controlled by two major genes, tu-1 on the first chromosome and tu-3 on the third chromosome. Much interest has centered around the nature of the growths. The histologic appearance of the tumor in the adult is already known. Previous attempts had been made to detect the first appearance of the abnormality in the …

A Revision Of The Genus Osmia, Subgenera Osmia, Chalcosmia And Cephalosmia (Hymenoptera: Megachilidae), Richard W. Rust

Biology

This paper is a taxonomic revision of the bee subgenera Osmia, Chalcosmia and Cephalosmia of the genus Osmia in North America. Cephalosmia occurs only in North America, while Osmia and Chalcosmia occur also in the Old World. Fifteen species and three subspecies are treated: one species, Osmia (Chalcosmia) alamedensis, is described as new, and one species, Osmia (Osmia) cornifrons (Radoszkowski), is new to the North American bee fauna. Two names are placed in synonymy for the first time, and one other name occurs in a new subgeneric combination. Although primarily a taxonomic thesis, this …

Vocalizations Of The Long-Billed Curlew, Dennis M. Forsythe

Biology

Avian vocalizations have been of great interest to ethologists and ornithologists for many years because of the many forms of interspecific and intraspecific information they convey (Marler, 1959; Armstrong, 1963). Various methods have been utilized to describe bird vocalizations but most, because of their subjectivity, have proven inadequate for detailed investigations. It was not until the development of the Sound spectrograph that a satisfactory method for bio-acoustical analysis became available.

The Effects Of A Selective Membrane Filter Medium On Fecal Coliforms, Donald Jesse Mcgraw

Biology

A bacterium reported to be indicative of human (or mammalian) fecal pollution is Type I (fecal coliform) Escherichia coli. Although this type may be isolated by use of elevated temperature (44.5 C), primary isolation without enrichment is difficult. Direct study without primary enrichment is possible with mFC Medium (Difeo), however, routine work in this laboratory yields poor results when mFC medium is compared with the standard EC elevated temperature technique. Using three strains of Type I E. coli, this study attempted to determine some reasons for the low recovery in mFC medium. The test organisms, preadapted to 37 …

Various Aspects Of Social Organization In Caged Groups Of House Sparrows (Passer Domesticus), John R. Watson

Biology

In order to study various aspects of social organization in House Sparrows (Passer domesticus), eight groups of sparrows were observed under captive conditions from January 1965, through October, 1965. Each group contained one adult male who secured a high win-loss ratio. However, the establishment of a straight line hierarchy was blocked by site-related dominance. The aggression exhibited by the alpha male was in defense of roost site and not a form of social organization. Juveniles were treated as adult females by adults of both sexes. Juveniles showed a marked ability to defend against adult males. Activity patterns were …

A Taxonomic And Life History Study Of A New Species Of Phlebotomus (Diptera: Psychodidae), Darrell N. Warner

A new species of Phlebotomus is named P. similis n. sp. It is closely related to P. vexator coquiIlet, differing in minor detaiIs, the most pronounced of which is the shape of the paramere. Its known distribution includes northern and southern Utah, and southern Arizona. Descriptions and iIlustrations of various life stages of the new species are given along with a detailed account of its life history.

Leaf Cutting As A Factor In The Insecticide Susceptibility Of The Alfalfa Leafcutter Bee (Megachile Rotundata-Hymenoptera: Megachilidae), Gordon D. Waller

Biology

The results of various laboratory tests have shown Megachile rotundata to be generally more resistant to insecticides than are Apis mellifera or Nomia melanderi. This greater resistance is not substantiated in field tests and observations, where M. rotundata appears to be highly susceptible to most insecticides. Its biological peculiarity of using alfalfa leaf cuttings for building cells may account for these conflicting results. Consequently, studies were initiated to determine the part played by the leaf cutting habit in the danger of insecticides to this bee. Two types of exposure were studied. In the first, either the source of nectar …

Food-Related Movements And Incidental Observations Of The Cliff Chipmunk, Eutamias Dorsalis, Eugene Blake Hart

Biology

Field work for this study was performed at the Beirdneau Cliffs, Logan Canyon, Utah, during May, June, and July, 1965 and 1966. Life history observations and data on the Cliff Chipmunk are presented and discussed. Summaries of seven "sub-seasonal" ranges are presented, based upon frequency of use of eight major preferred food plants.

Factors Influencing Population Growth Of Tribolium Brevicornis In The Laboratory, Amin Gulla

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To determine the effect of the factors of the environment (temperature, relative humidity, and food) on the population growth of Tribolium brevicornis, different levels of temperatures from 17.5°C - 37.5°C were used. Effect of these IeveIs of temperatures was tested upon both pre-embryonic and post-embryonic development. No hatching occurred at 17.5°C, but the threshold temperature (the minimum temperature for the development) was just before 17.5°C. The optimum temperature for the embryonic development was found to be between 32.5°C - 35°C.

With the use of the saturated salt solution according to Buxton (1931) and Buxton and Melanby (1934), certain humidity …

An Examination Of A Putative System For The In Vitro Synthesis Of Drosophila Tryptophan Pyrrolase, John P. Phillips

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A system, reported by Morrison (1964), for the in vitro synthesis of Drosophila tryptophan pyrrolase has been critically studied. This putative system is based on the addition of a Drosophila "RNA" extract to a Drosophila cell-free protein synthesizing system; the synthesized enzyme is then allowed to catalyze a specific reaction, the product of which is measured by direct adsorption.

The results of this study present a three-fold argument against the interpretation of synthesis of tryptophan pyrrolase in the Morrison in vitro system: (1) RNA from a null-allele, v^36f, stimulated the same tryptophan pyrrolase "activity" in the in vitro …

Inventory Of Economic Understanding Of Sky View High School Graduates, 1966, J. Karl Worthington

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

All societies are faced with the problems of what to produce, how to produce, and for whom to produce goods and services. To each of the many facets of each of these questions are many alternatives. The different economic systems in the world allow different segments or parts of the system's population to select the answers to economic questions from the alternatives to the economic questions all systems face. The quality of the decisions made is of vital importance to the progress of the particular economic system.

Estimation Of Parameters Of Normal Populations From Truncated Samples, Kuo-Chung Liang

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

In statistical experiments, if a random sample of items drawn from a population is tested until all items fail, conventional statistical techniques may be employed but normal frequency distributions may not be satisfied. Failure of the data to satisfy the assumption of normality may lead to an invalid result. Some statistical results, however, have been shown to be robust to the failure of the data to meet normality. When using conventional experimental methods, considerable time and money are required to produce failure of all samples. To be economical, many experiments are concluded before all test items fail. A sample obtained …

The Adolescents Preference For Counselors In Relation To Their Degree Of Religious Conviction, James W. Fitch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In a highly complex culture, there are numerous factors that influence ones life. The more industrialized societies promote tremendous structure for the entire population. The past World War II era has been labeled "The Age of Anxiety" (28, p.3). In some respects children are being forced to mature at an earlier age. The "storm and stress" period of the adolescent is receiving considerable recognition in our current literature and the adults are taking on increasing amounts of structure which are all resulting in more complex culture.

Movement Of Atrazine In Soil Under Furrow Irrigation, Jyothi Veerabhadrappa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Movement of atrazine in response to furrow irrigations was studied using the samples of Timpanogos silt loam soil. Distribution in soil profile of surface applied herbicide was determined by drawing samples of water extracts through porous cylinders. Atrazine quantity was determined by spectrophotometer.

It was observed that the herbicide found in the water extracts was an indication of the quantity present in the soil. The herbicide moved readily with the applied water. Irreversible thermodynamic model could not be applied because of the initial and final boundary conditions. The pattern of movement was in conformity with the chromatographic theory.

The Influence Of Thermo-Gradients Upon Water Movement And Retention In Unsaturated Soils, Jose V. Salazar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Temperature differences of about 5, 10, and 15 V, were applied to uniformly packed and insulated horizontal column of Millville silt loam soil using mean temperatures near 13, 14, 15, 16, 17, 18, 19, 20 and 23.5 C. The temperature distribution along the soil column was determined using copper constantan thermocouples. Soil samples were taken to determine volumetric moisture content, and soil water potential, using the vapor pressure psychometer technique. The thermodynamic flow equation of Taylor and Cary, (1964) was used to calculate the hydro-thermal transfer coefficient (ß) as given by:

-ß = d(μ_w)_T / dlnT

where …

Feeding Ecology And Territorial Behavior Of The Yellow Warbler, Merrill J. Frydendall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A controversy dating from the appearance of Altum's book, Der Vogel und sein Leben, 1868 (Mayr, 1935) is that of the biological function or functions of the territorial behavior in birds. However, attention was not focused upon this problem until the advent of Howard's book, Territory in Bird Life, published in 1920. In a general review of the problem Hinde (1956) discussed several functions of the territory and presented evidence both for and against their importance. The more important of these presumed functions are: (1) limitation of population density; (2) facilitation of pair formation and maintenance of the …

The Ecology Of The Black-Bellied Tree Duck In Southern Texas, Eric George Bolen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The black-bellied tree duck (Dendracygna autumnalis) is one of eight tree ducks (whistling ducks) in the genus Dendracygna. This group shares enough characteristics--reticulated tarsus and symmetrical syrinx structure, among others--with the swans and geese to warrant a common subfamily, Anserinae of the waterfowl family Anatidae. DeIacour and Mayr (1945) make a tribal distinction, however, between the tree ducks (Dendracygnini) and the swans and geese (Anserini) based, in part, an differences in size, vertebrae number, and downy plumage. These same authors remark that the tree ducks are the least known of the waterfowl largely because there are no …

Some Methodological Problems In The Economic Appraisal Of Increments Of Irrigation Water, David L. Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary objective of this study was to establish a production function for alfalfa grown in the Sevier Valley using farm survey data. A secondary objective was to point out the analytical difficulties in establishing a production function for alfalfa.

A multiple regression model using 12 linear, 12 nonlinear, and 7 interaction terms was employed. A coefficient of determination of .70 was obtained for the model. Intercorrelation problems associated with the model limit its usefulness for economic and predictive purposes. The predictive value of the model was greatly increased by reducing the number of correlated variables included in the model. …

Determination Of Estrone, 17b-Estradiol And Estriol In Urine Of Young Adults, Shiao-Fan Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study was made of the urinary excretion of estrogens of healthy university students consuming self-selected diets living under home conditions (4 men and 5 women). Two 31-day test periods were used. During the two test periods, two meal patterns were used; three meals a day or two meals a day with no lunch. Weight was kept constant. Calories, protein, carbohydrate, and fat of their diets were calculated.

Urine specimens were collected twice a week, and additional samples were also collected on specified days for female subjects. Urinary estrogens were determined by using Brown's method (1955, 1957) with some modifications. …

Fluoroorganic Compounds In Relation To Hydrogen Fluoride Exposures In Leaves Of Glycine Max Merr., Julie Ye-O Cheng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soybean plants were fumigated in HF and the organic acid-fractions of the leaf extracts were compared to those of the leaf extracts from soybean plants grown in nutrient solution containing fluoroacetate. The extracts from both treatments contained fluoroorganic compounds that were chromatographically similar to fluoroacetate and fluorocitrate.

The fluorocitrate separated from HF fumigated leaves was found to inhibit aconitase prepared from pig-heart. This inhibition was similar to that caused by commercial fluorocitrate and the fluorocitrate synthesized using guinea-pig kidney. The aconitase from soybean leaves was found to be sensitive to fluorocitrate as the aconitase that isolated from pig-heart. Inorganic fluoride …

Evaporation And Evapotransipration In Venezuela, Hidalgo Guillén Echeverría

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Equations and tables for estimating Fuess evaporation from climatological data were developed. Ten years of average records from 22 stations in Venezuela were analyzed in order to develop the equations.

Mathematical regression analysis, and plotting and computer programs were used to work out the equations. The form of the final expression for estimating Fuess evaporation is as follows:
Ev = K C_RC_TC_WC_HC_DTC_SC_M
Pan evaporation was computed using the Christiansen, Mathison, Blaney-Criddle, Hargreaves, Penman, and Kohler formulas. The computed pan evaporation from these formulas, measured Fuess evaporation, and …

A Method For Quantifying The Effects Of Apomorphine Upon The Gnawing Syndrome Of The Rat, Paul Robinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Various methods were tried in an attempt to obtain a technique for quantifying the gnawing effects of apomorphine on rats. A technique using a restraining tube was developed.

Under a 2 milligram per kilogram intraperitoneal injection of apomorphine, four female Long Evans hooded rats were placed on continuous and fixed reinforcement schedules using a gnawable pine block. Subjects would learn to turn their heads away from the gnawable object in order to obtain 15 seconds of gnawing time. The rate of response increased from less than one response in 5 minutes to over 3 responses per minute in 10 one-half …

The Biosynthesis Of Aminolevulinic Acid In Relation To Iron And Enzyme, Daniel Ming-Yi Teng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The survey of plant species for aminolevalinic acid synthetase (ALAS) source was conducted. Under the conditions of this study, spinach leaves were found to be a good source of ALAS activity. The amount of amino levulinic acid (ALA) synthesized by the plant extracts was very small and was rapidly metabolized to porphyrins. ALA and porphyrin synthesis was found to be confined to the particulate fractions. Rupturing of the particles with ultrasonifier enhanced the penetration of succinyl-CoA and increased the activity. Direct study of the ALAS activity was enabled by the utilization of C¹⁴-compounds to the isolation by column …

Interaction Of Inorganic And Organic Fluoride Ions With Available Calcium On Root Growth In Triticum Vulgare, L., Subbanaidu Ramagopal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A method has been described to suspend seedling wheat roots in a saturated atmosphere. Wheat (Triticum vulgate, L.) seeds were germinated in aluminum trays and the seedlings transferred to seedling chambers. After a day's growth, the roots were treated with various concentrations of solutions containing CaSO₄, KCl, KF, NaCL, NaF, CH₃COONa, FCH₂COONa, K₂C₂O₄ and Na₂EDTA and observations were recorded 24 and 48 hours after treatment. The new root growth was described with respect to root hairs, root tissue collapse and root discoloration. Total length and …

The "Starvation Effect" And Tryptophan Pyrrolase Activity In The Vermilion Mutant Of Drosophila, Ernest E. Shelton Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The enzyme tryptophan pyrrolase is controlled by the vermilion locus in Drosophila melanogaster and is normally lacking in the vermilion mutants. During this investigation it has been demonstrated that v¹;bw flies have tryptophan pyrrolase activity when grown under near starvation conditions.

During development of the fly there is a peak of enzyme activity in the early third instar soon after the transfer to starvation medium. A second peak of enzyme activity occurs during the pupal stage. The activity in v¹;bw pupae is about 15% of the activity found in cn bw adults.

In v …
