Density-Gradient Centrifugation: Non-Ideal Sedimentation And The Interaction Of Major And Minor Components, Myron K. Brakke, J. M. Daly

Department of Plant Pathology: Faculty Publications

A small amount of southern bean mosaic virus was contained in a narrow zone after density-gradient centrifugation, but in a much wider zone after centrifugation with a large amount of a second virus. Zone-spreading of a major component by non-ideal sedimentation in density-gradient centrifugation can cause zone spreading of a minor component that the major component overlaps.

Hormonal Control Of Reproductive Activity In The Ewe, J. F. Wagner

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

There are many advantages which result from synchronizing the estrous period in a ewe flock. In situations where the ewes are not hand bred to the ram, the synchronization of estrus makes the application of artificial insemination (AI) techniques more efficient. Detection of estrus usually is more reliable in a synchronized flock. Only 3 to 4 days are needed to detect estrus in 90 percent of a synchronized flock, whereas 16 to 18 days are normally required. This allows the AI technician to plan the number of breedings and have semen available. When hormones are given in the feed, an …

An Analysis Of Economic Factors And Institutions Affecting The Productivity Of South Dakota Land And Water Resources For Upland Game Birds And Migratory Waterfowl, Arthur J. Matson

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

This study examines the role of government at the state level in the allocation of land and water resources which supply recreational products for which there is economic demand. Two approaches are employed with special reference to South Dakota. One approach considers the productivities of resources which provide goods and services according to consumer choice. The other approach analyzes policy decisions and the means by which society, organized through government, is able to move toward a goal of maximization of satisfactions. The two approaches are highly interrelated. Attention is given (1) to the jurisdiction of a state over the factors …

Pattern Selection And Alteration, Lenore Landry

SDSU Extension Circulars

A pattern is a blueprint-a precise measuring device. Following this blueprint carefully doesn't always insure the success of a garment, unless you first select the right pattern. The first half of this circular tells what you need to think about and do before making that selection. The second half is about altering patterns. You'll note that this publication is written primarily to help you sew for yourself. However, you may want to apply the information to sewing for other members of the family and friends.

Second Bibliography And Index For The Philosophy Of Geology, Claude C. Albritton Jr.

Journal of the Graduate Research Center

The body of writings on the philosophy and history of geology has grown in a remarkable way since the end of the Second World War. There is no obvious explanation for this quickening of interest in what are surely the most academic aspects of a science best known for its practical applications. Influences arising both from within and from outside the geological profession have probably been responsible. It is a matter of record that many departments of geology, upon resuming full-time operations after the war, decided not to go on moving in the old curricular ruts. The new courses, even …

Laminating Wood Components Of Varying Individual Thickness, Jere Murphy Cary

Graduate Student Research Papers

This paper deals with a new process in woodworking—one which overcomes some old woodworking problems in lamination. In the paper, the writer will justify and explain the process of lamination, the history of lamination and the justification of laminating wood components of varying individual thickness. The actual mechanical processes—the how to do it—is described as well as some possible uses of the process.

Biochemical Changes During The Growth Of Fungi: I. Nitrogen Compounds And Carbohydrate Changes In Penicillium Atrovenetum, David Gottlieb, James L. Van Etten

Department of Plant Pathology: Faculty Publications

Changes in the biochemical constituents of cells were studied during the growth and development of Penicillium atrovenetum. Growth of the fungus, as measured by the dry weight, could be divided into four phases: lag, log, stationary, and death. The percentages of total nitrogen, cold trichloroacetic acid-soluble nitrogen, ribonucleic acid (RNA), and protein increased to a maximum during the lag phase, and subsequently decreased as the fungus aged. The percentage of deoxyribonucleic acid (DNA) was always slightly higher in the spores than in the mycelium. The DNA in the mycelium decreased in the lag phase, and then increased slightly to …

Relation Between Use Of Lincomycin And Outgrowth Of Yeast, Howard W. Clapp

Masters Theses

Introduction

The use of antibiotics has increased the average life expectancy of mankind. They have prevented and cured infectious diseases that previously terminated in death. Consequently, recovery is often prompt and complete.

Though a benefit to mankind, the use of antibiotics in the treatment of infectious disease has also been accompanied by new problems. For example, treatment of a primary infection such as a bacterial pneumonitis with a broad spectrum antibiotic, may result in the death of some of the bacteria. More than one species of bacteria, however, are often found in the infected area. If such be the situation, …

Phytotoxic Substances From Soil Microorganisms And Crop Residues, T.M. Mccalla, F.A. Haskins

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

The role of organic matter in the growth of plants has been a subject of much investigation and controversy since the sixteenth century. During the early era, decomposition of plant residues and green and animal manures provided a primary source of minerals for plant growth. In addition, beneficial effects on soil structure and water-holding capacity were attribute to the presence of organic matter. With the development of agricultural chemistry culminating in the work of Liebig in the nineteenth century, it was discovered that plants could make satisfactory growth in the absence of added organic matter if suitable kinds and amounts …

Investigation Of Possible Autotoxicity In Daucus Carota L., Carole Greer Smith

Masters Theses

Section I

Introduction

Results of recent research indicate the probable existence of plant-produced chemical substances which affect the behavior of other plants. Germination-inhibiting, and growth-inhibiting substances have been found to be widely distributed throughout the Plant Kingdom (Garb, 1960). Although the presence of inhibitors has been demonstrated in laboratory experiments, their ecological significance has not been clearly defined.

A preliminary study by the writer indicated the probability of autotoxicity in Daucus carota L., a biennial common to fields and roadsides in the northeastern United States. This study suggested the following investigation which was undertaken to determine more specifically the effects …

A Study Of Door Pulls On Isolation Carts In A General Hospital For Evidence Of Contamination, Mary Alice Harper

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of the study was to find out if isolation carts were serving as a means of cross infection. Literature pertaining to sources of possible contamination on hospital units written in the past five years were reviewed.

Using the descriptive survey as the method of study, effort was made to find out if isolation carts were a means of cross infection on the hospital unit. Two laboratory cultures were obtained from both door pulls on all isolation carts used by nursing units. This was done over a three month period from December 12, 1963 to March 11, 1964. The …

Electromyographic Analysis Of The Temporal And Masseter Muscles During The Para-Retentional Period In Orthodontic Patients, Thomas L. Thompson

Loma Linda University Electronic Theses, Dissertations & Projects

This study was initiated to compare electromyographically the activity of the masseter and temporal muscles during the early retentional period in orthodontic patients. Electromyographic recordings were taken at the following times: (1) before typical edgewise appliance was removed, (2) at time of retainer insertion, (3) after eight to twelve weeks of retainer wearing, and (4) one day following occlusal equilibration. Electromyograms from the orthodontic group of subjects were compared with electromyograms from a group of subjects with normal occlusion, and a group of subjects with untreated Class II, Division 1 malocclusions. There was a total of thirteen subjects studied: five …

A Study Of The Effect Of Varying Serum Phenylalanine Levels On Changes In Intelligence Quotient, Darlene Imai Manullang

Loma Linda University Electronic Theses, Dissertations & Projects

Data from thirty medical records of phenylketonuric children under treatment were investigated to determine at which serum phenylalanine level (0-3.9 mg. %, 4-7.9 mg %, 8-11.9 mg. %, greater than 12 mg. %) there would be the greatest increase in intelligence. The children involved in the study were divided into the following groups according to the age dietary treatment was initiated: 0 through 5 months, 6 through 11 months, 12 through 23 months, and over 2 years of age.

Among 6 patients who were placed on the diet during the first 5 months of life, it appears that the optimal …

Nucleic Acids And Protein Synthesis, Sheldon Nicol

Honors Projects

The unprecedented growth of interest in protein synthesis among biochemists is both a result of, and has contributed to, our rapidly advancing knowledge of the chemistry and metabolism of the nucleic acids. Over the past two decades, evidence has accumulated which points to an intimate association between cellular nucleic acid and protein synthetic activity. A large number of experiments in bacterial systems have shown that ribonuclease disrupts the cell's protein synthetic machinery and that ribonucleic acid (RNA) can frequently restore it. Studies of bacterial transformation (Hotchkiss, 1957) and the discovery of the autonomous infectivity of tobacco mosaic virus RNA (Gierer …
