The Effects Of Sources And Levels Of Vitamin A And D On Some Aspects Of Sulfur Metabolism, Akbar Malekpour

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two trials were conducted using 48 infant pigs of both sexes. Pigs were taken from the sow when three to seven days old and placed in wire-bottomed metal cages by pairs. Animals in the first trial received synthetic diets containing 100 or 1000 international units of ergocalciferol and 1000 or 4000 international units of retinyl acetate or four or sixteen milligrams of beta carotene per kilogram of feed. Baby pigs in the second trial received the same synthetic diet plus 1000 international units of ergocalciferol (D₂) or cholecalciferol (D₃) and 2000 international units of vitamin A …

Raffinose In The Sugarbeet (Beta Vulgaris): I. Biosynthesis And Degradation In The Root; Ii. Hydrolysis In Molasses With Sweet Almond Emulsin, Te-Chao Chuang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

PART I

The precursors for the biosynthesis of raffinose in sugarbeets were studied.

An enzyme preparation was obtained from the sugarbeet (Beta vulgaris) root. Incubation of this enzyme with (X-galactose-1-phosphate, Uridine triphosphate (UTP), Adenosine triphosphate (ATP), Magnesium chloride (MgCl₂), and L- cysteine at pH 5, 10°c for 6 hours formed a compound which was identified as raffinose by a hydrolysis method and thin- layer chromatography. The same result was obtained when Uridinediphosphate (UDP)-galactose was incubated with sucrose, ATP , MgCl₂, and L- cysteine in the presence of the beet enzyme preparation. These reactions suggested …

Effects Of Water Hardness On Processed Quality Of Carrots, Sweet Cherries, And Apricots, Jack C. Chiang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Honey Sweet carrots were canned with Ethyienediamine tetracetic acid (CaNa₂EDTA) and Sodium hexametaphosphate (Ha-HMP) at five different water hardness (0 , 20, 40, 80, 160 ppm of calcium and 20 of magnesium) , then stored at temperatures of 70 and 100 F. Evaluations were made at sixty-day i intervals for six months. Firmness and color degradation decreased significantly when water hardness or storage time increased. Under storage at 100 F and 0 hardness of water, the decrease of color and firmness was constantly accelerated.

When hard water (above 80 ppm or below 40 ppm) was used for …

The Morphological, Anatomical, And Histochemical Effects Of Eptc On Oat Seedlings, Jacinta Yu-Rui Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Morphological, anatomical, and histochemical effects of S-ethyl dipropylthiocarbamate (EPTC) on Avena sativa var. overland were studied after treatment of seeds at various EPTC concentrations.

The oat seed germination percentage was not affected by EPTC treatment. EPTC delayed initial root and coleoptile development at all concentrations used. Two or three days after treatment, however, the roots of seedlings treated with EPTC concentrations lower than 3 ppm grew at the same rate as the untreated seedlings and showed no abnormalities. Primary and adventitious root growth of seedlings treated with 3 ppm and higher was inhibited. Most of the adventitious roots remained in …

Hereford And Holstein Steer Performance On High Grain Diets With And Without Corn Silage, Cyril Bruce Russell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A factorially designed experiment had 18 Hereford and 18 Holstein steers on individually fed, high-grain diets. One diet included 59% rolled barley, 30% CSF beet pulp, 5% protein, vitamin, mineral, and stilbestrol supplement, and 6% chopped hay and straw. The other diet had corn silage (11% air dry matter equivalent) substituted for the chopped roughage and 5% of the beet pulp. The Holsteins were heavier at the start, 752 lb. as compared to the Herefords 686 lb. average. The weight differential was maintained throughout the approximately 180-day trial. The Holstein's feed consumption and rate of gain, 23.4 and 2.71 lb. …

Each person was asked to evaluate each curriculum area according to four suggested rating values: no value, has value, recommended, or essential.

The rating from each respondent was tabulated for each curriculum area by total points by numerical …

Selected Physio-Chemical, Microbiological, And Agronomical Studies On The Controlled Atmosphere Storage Of Sugarbeet (Beta Vulgaris) Roots, Vinod V. Karnik

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The post-harvest physiology of sugarbeet (Beta vulgaris) roots was studied during controlled atmosphere (CA) storage at 35° and 50°F. Zero, 3, 6 and 10% carbon dioxide and 5% oxygen concentrations were employed to investigate the most beneficial concentrations of gases. Under the experimental conditions beets were stored successfully for 200 days. The maximum beneficial effects of CA were observed under 6% carbon dioxide and 5% oxygen at 35°F. Regardless of storage temperatures, sucrose retention was highest in the beets stored under CA, compared to conventional refrigeration (CR). Other beneficial effects include less hydrolysis of sucrose to reducing sugars …

Bench Marks From Which Economic Change Can Be Measured For An Altiplano Community, Roberto Julio Gonzalez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis is designed to establish bench marks which will facilitate the measurement of impacts of new crop and livestock extension practices on the rate of community development of the village of Achica Bajo, Bolivia. Successful agricultural extension and community development programs require adequate data at the farm and community level. In the absence of a real appreciation for the levels of income and financial needs of the campesinos, it is difficult to institute farm policies such as land tax measures which will have the desired impacts and consequences as well as peasant acceptance.

The study examines human and …

A Forecast Of Iranian Demand For Agricultural Food Products, Ivan F. Beutler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Domestic demand for Iranian agricultural food commodities was projected for 1970, 1975 and 1980. Demand for particular commodities was projected separately for Tehran (the capital city), urban Iran and rural Iran.

Income and population growth were the most significant explanatory variables in this long term projection.

Two cross-sectional family budget surveys, taken six years apart, provided consumption data for Tehran and urban Iran. A series of family budget studies provided Engel curve data for rural Iran.

The income effect was estimated for each food item by least squares regression analysis. The resulting income elasticities were found to be significantly different …

An Investigation Of The Mode Of Action Of 2-Chloro-N-Isopropylacetanilide, Nirmal S. Dhillon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Corn (Zea mays L.) seedlings possessed a high degree of tolerance to growth inhibitory effects of pre-emergent application of 2-chloro-N-isopropylacetanilide (propachlor), squash (Cucurbita maxima Duchesne) was intermediate in its response to the herbicide followed by oats (Avena sativa L.), lambsquarters (Chenopodium album L.) and redroot (Amaranthus retroflexus L.). Root growth was more severely retarded by lower concentrations of propachlor than was stem development.

Propachlor inhibited cell division in onion (Allium cepa L.) root tips. Aberrations in the mitotic behavior, such as contraction of chromosomes, was also induced. Cell elongation, in particular auxin …

Growth Of Eimeria Alabamensis From Cattle In Vitro And The Changes In Fine Structure Associated With Schizogony, J. Robert Sampson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Monolayer primary cultures of cells from bovine embryonic intestine (BEint), kidney (BEK), spleen (BES), and thyroid (BET) and cell line cultures of embryonic bovine trachea ( EBTr) and synovium (BESy)as well as established cell line cultures of Madin-Darby bovine kidney (MDBK), human intestine (Int 407), and Syrian hamster kidney (BHK-21) were inoculated with freshly excysted sporozoites of Eimeria alabamensis and observed for 4 days. Sporozoites penetrated all cell types during the first 24 hours in culture. Numerous intracellular sporozoites, trophozoites, and binucleate schizonts were seen in all cell cultures except Int 407. The best development occurred in BES and MDBK …

The Evolution Of Parasitism Among Bees, George E. Bohart

Faculty Honor Lectures

Before discussing parasitic bees, I will present a rough outline of the biology of "ordinary" or non-parasitic bees. The superfamily Apoidea (bees) includes perhaps 25,000 or 30,000 species divided into nine families by recent authorities (Stephen, Bohart, Torchio, 1969) . A common biological thread holding this vast assemblage together is the provision by adults of pollen and nectar for their young. Only in the honey bees (the genus Apis which includes four species) are the larvae fed primarily on a different substance (a secretion of the pharyngeal glands) , and even this is derived from pollen and honey eaten by …
