1962 Annual Report : Extension Service Indian Program In South Dakota, Cooperative Extension Service, South Dakota State College

SDSU Extension Circulars

Because of great differences in economics and people on each reservation area, it is not possible to set forth in this report the specific objectives of all programs conducted. Several broad objectives were therefore selected for major program emphasis. They are: To strengthen and encourage adult responsibility in community living through leadership training. To encourage through training programs greater utilization of the unemployed and underemployed human resources of the reservation population. To teach better nutrition and food habits and to improve the uses of surplus food commodities distributed to welfare clients. To teach sound ranch management principles to Indian ranch …

The Influence Of Salinity On The Growth And Reproduction Of Marsh Plants, D. K. Kaushik

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The water resources of the State of Utah are rapidly being developed for agriculture and industry. They are so extensively exploited that their continued and additional use must be justified on the basis of need and efficiency of utilization. To determine more accurately the quantity and quality of water needed to operate a marsh, a project was undertaken by the Utah Department of Fish and Game, the Engineering Experiment Station and the Cooperative Wildlife Research Unit at Utah State University. The study was divided into the two phases, one on quantity and one on quality of water. The present report …

Biosynthesis Of Infectious Cucumber Mosaic Virus Ribonucleic Acid In A Cell-Free Medium, Men Hui Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The mechanism of biosynthesis of the nucleic acids, RNA, remained obscure until 1955 when the announcement was made (14) that an enzyme isolated from bacterial sources catalyzes the synthesis of ribopolynucleotides from nucleoside-5'-diphosphates. It has been shown that the biosynthesis of polynucleotides occurs through the stepwise polymerization of nucleoside-5'-diphosphates or triphosphates. A great deal of research over the past few years has indicated that isolated nuclei from both animal (1) and plant (19) sources are able to synthesize ribonucleic acids in vitro (18).

The Nitrification Of Ammonium Sulfate In Polyethylene Bags In The Field And Laboratory, Carlos Dean Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are many advantages and some disadvantages associated with the fall application of nitrogen fertilizers. The advantages of applying fertilizer at this time appear very convincing. It is easier to get onto the land in the fall. During the fall, farmers usually have more time to apply fertilizer than they do in the spring. In the fall the fertilizer companies offer better services. This is because the fall application of fertilizer lengthens out their season, thus making it possible for them to handle more fertilizer.

The main disadvantage is the fact that it is possible to lose the fall-applied nitrogen …

Nitrogen Effect On Cation Exchange Capacity Of Plant Roots, Kamilia Shoukry Mohamed Shoukry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationships that exist between soil and plant are very complicated and have aroused man's curiosity for centuries. Many studies have been done in order to understand and clarify this relation. Among these is the hypothesis that plant roots exhibit cation exchange capacity (CEC) and that this is in some way responsible for differential cation uptake . The CEC of the roots was defined by Helmy (l958a) as the total cations which can be exchanged or replaced from the root surface under a given set of conditions and is usually expressed as milli-equivalents per 100 grams (me/100 g) of dry …

The Respiratory Chain Involved In Oxidative Phosphorylation On Higher Plants In Relation To Carbon Dioxide-Bicarbonate Inhibition, Wan-Jean Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Increased concentrations of CO₂ with the accompanying high bicarbonate level in the culture medium have been reported to have a depressing effect in certain plant species on growth (34), respiration (23, 33), oxidative phosphorylation (9), mineral nutrient absorption (17), certain enzymatic reactions (4, 22, 27), accumulation of organic and amino acids (11), and protein synthesis (16). Since accumulation of organic acids occurs in lime-induced chlorotic tissue together with a depression in the respiration of plant tissue, an effect on the energy transfer mechanism of such plants is suspected. Inhibition of electron transfer from the substrate level could result in …

The Inhibition Of Seedling Growth By Crop Residues In Soil Inoculated Wlth Penicillium Urticae Bainer, D. E. Behmer, T. M. Mccalla

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

In the Great Plains area of the United States, stubble-mulch practices have been widely used in the control of soil erosion by wind or water. Although this method of leaving crop residue on the surface has been very effective in combating erosion, depressed plant growth and reduced grain yield have often occurred in wet years. Similar growth problems have been observed during unseasonably cool, wet springs in field experiments at Lincoln, Nebraska. Because increased numbers of certain micro-organisms occur immediately beneath a decomposing surface mulch, the production of phytotoxic compounds under these conditions may well have been associated with the …

Effects Of Food, Temperature, And Oviposition Site On Longevity And Fecundity Of The Army Cutworm, K. P. Pruess

Department of Entomology: Faculty Publications

Longevity of the army cutworm, Chorizagrotis auxiliaris (Grote), following mating was inversely related to temperature. Females lived longer than males at all temperatures, and food increased longevity of both sexes. Oviposition occurred at 70° and 55° but not at 32° F. None of the variables tested affected total fecundity but oviposition was completed sooner at 70° than at 55°, in sand as an oviposition site vs. paper toweling and by unfed than by fed moths. Starvation preceding oviposition did not affect fecundity but speeded completion of oviposition when moths were returned to favorable conditions.

The Family And Free Time, Merle Gunsalus

SDSU Extension Circulars

Today Americans have more leisure than any people have ever had; yet they seem to find little real enjoyment in what they do. A recent observation suggests that the poverty-stricken may soon be replaced by the leisure-stricken. People are indulging in more activities, going more places, spending more money than ever before; yet few recognize the need for more thoughtfulness about the use of leisure time in family living.

Animal And Plant Viruses With Double-Stranded Ribonucleic Acid, Peter Gomatos

Student Theses and Dissertations

Reoviruses occur widely in the respiratory and enteric tracts of man and animals, but their relation to disease is not clear. The present study concerns the physical-chemical characteristics and interaction with cells of reovirus type 3. A main objective of the study is to relate some of the distinguishing biological characteristics of the virus to the structure of its RNA. Reoviruses are medium-sized, icosahedral viruses with a diameter of 75 mμ, and they contain RNA. The protein coat of the virus is composed of either 5- or 6-sided prismatic subunits, 92 in all. Each structural subunit of the protein coat …

Biochemical And Biological Studies On The Growth Of An Rna Containing Bacteriophage, Stephen Cooper

Student Theses and Dissertations

The growth of the RNA-containing bacteriophage f2 has been studied. DNA synthesis appears normal after phage infection. It is possible to dissociate the synthesis of viral RNA from the synthesis of DNA using thymine-less bacteria with fluorinated pyrimidines and Mitomycin C as inhibitors of DNA synthesis. It is concluded that the growth of f2 is independent of DNA synthesis. Since the phage RNA has no special characteristics, its synthesis has been followed by using p32 to label RNA which is eventually incorporated into virus particles. Using this method of measuring phage RNA synthesis, it has been shown that the material …

A Study Of Ionic Permeability Changes Underlying Excitation In Myelinated Nerve Fibers Of The Frog, Frederick Arthur Dodge

Student Theses and Dissertations

Investigations by Huxley and Stämpfli of the dependence of the resting potential and of the action potential at the node of Ranvier upon the ionic composition of the bathing medium provided evidence that the electrical activity resulted from a sequential alteration of the membrane permeability to sodium and to potassium ions. Their results suggested that the nodal membrane conformed in a general way to the ionic hypothesis developed in detail for the squid axon by Hodgkin and Huxley. This dissertation reports an investigation of the electrical characteristics of the nodal membrane aimed at developing a quantitative formulation of the ionic …

Studies On Delayed-Type Hypersensitivity Including Attempts To Effect Transfer In Guinea Pigs With Subcellular Materials, Barry R. Bloom

Student Theses and Dissertations

The initial observation that delayed-type hypersensitivity could be transferred from an allergic to a normal animal by means of living white cells was made at The Rockefeller Institute many years ago. Since that time it has been recognized that cellular transfer appears to be a unifying principle underlying both contact dermatitis and tuberculin hypersensitivity. Later studies in man have suggested that the phenomenon can be reproduced with use cell-free extracts. Similar attempts have been made with extracts of cells from sensitized guinea pigs but, there exist only three reports in the literature which claim that transfer of contact or tuberculin …
