Solpugida Of The Nevada Test Site, Martin Hammond Muma
Brigham Young University Science Bulletin, Biological Series
Study of nearly 1,000 specimens of solpugids collected in 1960, 1961, and 1962 from Mercury, Nevada, resulted in the identification and placement of 395 adults in 28 species. Eight new species are described and figured. Two new synonymies, resulting from proper association of males and females, are cited. Study of the seasonal distribution and relative abundance of the sexes of 12 common species has prompted general and specific deductions concerning the essentially unknown biology of North American solpugids. Systematic collection data furnished ecological information concerning the 12 common species.

Performance Of Alfalfas Under Five Management Systems, W. R. Kehr, E. C. Conard, M. A. Alexander, F. G. Owen
Performance Of Alfalfas Under Five Management Systems, W. R. Kehr, E. C. Conard, M. A. Alexander, F. G. Owen
Nebraska Agricultural Experiment Station: Historical Research Bulletins
This bulletin reports stands, forage yields, and other agronomic data on alfalfas of diverse origin or type tested under five management systems at Lincoln, Nebraska. Narrow-crowned and broad-crowned types were tested. The management systems involved non-irrigated alfalfa-bromegrass tests (a) continuously grazed with steers, (b) cut for hay, and (c) rotationally grazed with sheep; an irrigated alfalfa-bromegrass test rotationally grazed with dairy cattle; and irrigated tests of alfalfas in pure stands cut for hay.

Biosynthesis Of Infectious Cucumber Mosaic Virus Ribonucleic Acid In A Cell-Free Medium, Men Hui Lee
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).
Leaf Ribonuclease Activity As Related To Virus Infection, And Ribonucleic Acid Concentration, Andrew Chien-Yau Hsu
Leaf Ribonuclease Activity As Related To Virus Infection, And Ribonucleic Acid Concentration, Andrew Chien-Yau Hsu
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Ribonucleic acid (RNA) appears to be the entity responsible for infectivity and genetic continuity in certain plant, animal and bacterial viruses. RNA also plays an important role in protein synthesis. The enzymes which are involved in RNA synthesis and degradation have received much attention. Among these enzymes ribonuclease (RNase) has been most thoroughly studied Rnase is widely distributed and has been isolated from many sources such as snake venom, bacteria, the pancreas, and many plant and animal tissues. Most studies with RNase have been concerned with its role in the hydrolysis of RNA in vitro. Therefore, it has generally been …
The Respiratory Chain Involved In Oxidative Phosphorylation On Higher Plants In Relation To Carbon Dioxide-Bicarbonate Inhibition, Wan-Jean Young
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 …

Infrared Spectroscopy As Applied To The Study Of Biochemical Changes Induced By Tobacco Mosaic Virus In Leaf Cells, Banavara Krishnappa Chandrasekhar
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The biochemical reactions occurring during the early stages in the infection cycle of a plant virus are still unknown. Many studies involving bacteriophage and animal viruses that have been made in recent years have provided evidence of the nature of virus infection, but these have not been of much value in understanding the nature of plant viruses. Infrared spectroscopy applied to the study of viral infection processes by Chochran and his co-workers (1960, 1962) have given some clues about the nature of biochemical changes taking place in the leaf tissues as a result of infection with cucumber mosaic virus and …

This paper consitutes a terminal report to the United States Atomic Energy Commission for Contract AT(11-1)786. It provides a listing of the fauna known to occur at the Nevada Test Site, with designation of ecological distribution and relative density. It is designed to serve as the basic faunistic reference source, in subsequent studies, related to geographical and ecological features at the test site.
