Cacodylic Acid As A Silvicide, Maurice W. Day

Aspen Bibliography

This report deals with the effectiveness of cacodylic acid (dimethylarsenic acid) as a silvicide for undesirable trees. Cacodylic acid has been used successfully as an herbicide for the destruction of grasses and weeds. Experimental work with this material was begun during the 1963 field season, and continued during 1964, to permit complete evaluation of the results. It appears that cacodylic acid has considerable potential as a silvicide.

Preliminary Fresh And Dry Weight Tables For Seven Tree Species In Maine, Harold E. Young, Lars Strand, Russell Altenberger

Aspen Bibliography

Long range forecasts of the use of wood, independently prepared by the Forestry and Forest Products Division of the Food and Agriculture Organization in Rome and the Standard Research Institute in California, concluded that in the foreseeable future there will be only a slight increase in the consumption of lumber but a rapidly increasing use of products made from wood fiber such as paper and paperboard.

Since 1955 the use of weight as a basic unit of measurement for roundwood and chips has increased more rapidly than the consumption of products made from such material. In some portions of the …

Studies Related To The Control Of Anacamptodes Clivinaria (Guenée) (Lepidoptera: Geometridae), Harold W. Flake

Biology

Economic importance Anacomptodes clivinaria (Genee) is a serious pest of curlleaf mountain mahogany (Cercocarpus ledifolius) and bitterbrush (Prushia tridentata). Mountain mahogany and bitterbrush are important browse plants for wildlife and for watershed protection. In the winter, curlleaf mountain mahogany may serve as the major food source for wildlife because the leaves are retained year around (Flook, 1955). The deer and antelope winter ranges are some of the limiting factors in herd size and must be protected. Smith (1957) reported that curlleaf mountain mahogany has one of the highest percent nutrients of any winter browse plant for …

Topography Of The Abdominal Nervous System And A Review Of The Abdominal Musculature Of The Honey Bee Apis Mellifera Linnaeus, Nabil N. Yousef

Biology

Studies of insect nervous systems have lagged behind other internal morphological studies for various reasons, the more obvious of which are: the understanding of external morphology remains incomplete; techniques for staining and dissecting nervous tissue have not been fully developed; dissections are time consuming; associations of various nerves between different insect taxa are very difficult; and until the past two decades, the importance of the insect nervous system has been considered insignificant in applied entomology .

The Distribution Of Sialic Acid In Selected Tissues And Body Fluids During The Female Reproductive Cycle, Donald Reed Jensen

Biology

An intriguing and dynamic chapter in the history of biochemical research concerns the acylated derivatives of neuraminic acid, the so- called "sialic acids." These substances have been found to occur naturally as constituents of a wide variety of mucoproteins, mucolipids, and related compounds. Because of their vast distribution throughout the animal kingdom, considerable attention has been focused on the chemical, physical, and biological properties of these acids. Attendant studies have shown the functional integrity of certain of the protein and lipid conjugates to be dependent on the presence of sialic acid residues, thereby assigning physiological importance to the acylated derivatives …

The Multiplication Of Lambda And Lambda-Dg Within Their Lysogenic Host Escherichia Coli K12, Gerald D. Elseth

Biology

Bacteriophage λ and its variant λdg, present in the prophage condition within their lysogenic host Escherichia coli K12, can be induced to vegetative multiplication by irradiation with ultraviolet light. Experiments conducted within this laboratory to determine the intra-cellular synthesis of λ and λdg after lytic induction indicate changes in concentration ratios between the two bacteriophages. This change in ratio is dependent upon the growth conditions of the bacteria and the dose of ultraviolet light used for the induction process. Further investigation into this problem is needed and was the major objective of this thesis study.

Biological Studies Of Three Species Of Cuterebra (Diptera: Cuterebridae) From Northern Utah, Charles L. Graham

Biology

Flies of the genus Cuterebra are found in the New World only. They are parasitic bots of rodents and lagomorphs as larvae and have been studied for about one and one-half centuries. During this time very little has been found out about the biology of most of the species, even hosts are still unknown for many of them.

The Genetics Of Abnormal Head Morphogenesis In Drosophila Melanogaster, With Special Reference To Eyelessness, Homoeosis, Penetrance, Asymmetry, And The "Fourth" Instar, James Wesley Edwards

Biology

During experiments involving the addition of copper sulfate to the food medium (Turner, 1959) some files from the tu¹⁵⁰/Cy strain of Drosophila melanogaster exhibited a structural eye abnormality. By inbreeding those flies a new mutant stock was developed. Edwards and Gardner (1962) designated the stock as eyes-reduced and located the major genetic factor (eyr) in the right arm of the third chromosome. The eyes-reduced stock possesses characteristics which are challenging to current theories in genetics and development; the purpose of this investigation was to thoroughly study those characteristics.

The Use Of Amprolium In Controlling Coccidiosis In Calves, Ronald Fayer

Biology

Bovine coccidiosis is an economically important disease in the United States. The Agriculture Research Service (1954) reported that the annual loss caused by coccidiosis in cattle in the United States amounts to $10,000,000. Fitzgerald (1963) found in a survey of losses of calves under 1 year of age in the west northcentral and the western United States that approximately $11,000,000 is lost yearly because of mortality and morbidity from coccidiosis.

Inoculation Method And Treatments Which Increase The Sensitivity And Precision Of The Infectivity Assay Of Tobacco Mosaic Virus, Calvin Ray Lamborn

Biology

The active research in cell-free virus synthesis at this university has placed great emphasis on an improved procedure to assay virus infectivity. The conventional method used (finger inoculation) was simple, but low insensitivity and precision. Infectivity assays of plant viruses are complicated by large differences in susceptibility among local lesion hosts. Factors influencing the susceptibility are the age of the host and the environmental conditions under which the plants are grown, such as temperature, humidity, soil moisture, nutrition and lighting. Another problem is to get the virus into the host cell. The inoculation method has to cause enough injury to …

Histochemical Investigations Of The Effects Of Fluoride On Dehydrogenase Enzymes Of Pelargoniom Zonale, Clyde J. Hurst

Biology

The industrialization of the Intermountain West has brought with it the by products of industry. Of these by products, fluoride is of particular interest and importance, because of its toxicity to both plants and animals at low concentrations. There is a wide range of variation in susceptibility of different plants, but gladiolus, prune, apricot, and peach among others are very sensitive to fluoride in concentrations as low as 0.02 to 0.05 ppb (Katz, 1956).

A Study Of Morphological Characteristics To Determine Sex In Prepupal Bees, Ross A. Nielsen

Biology

Many solitary bees develop through the egg and larval feeding stages in a week or two and then enter a quiescent prepupal peri od lasting through the winter months. When diapause is broken, development proceeds to the pupal stage in which sex can be determined easily. In contrast, sex differentiation is not obvious in the earlier stages. Michaelis (1900) studied the postembryonic development of the genital organs in fixed specimens of honey bee larvae (Apis mellifera Linn.). This study was extended by Zander (1900) to include larvae of the genera Vespa and Bombus. Although neither of these authors …

The Influence Of Respiration On The Movement Of Water Through Tomato Root Systems, Ward Bryce Roberson

Biology

The rate at which water moves through the root system of a plant is influenced, in some way, by the metabolic activities of the living cells which compose the tissues of the roots. This conclusion is based on the fact that water movement and metabolic activity are similarly influenced by certain chemical and environmental factors.

Molybdenum-L-Histidine Complexes, Jiing-Yun Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

L- Histidine is a very important amino acid and is widely distributed in living systems. In the growth and multiplication of animal cells, it was found that L-histidine is one of the amino acids that must be present. From the kinetic studies of certain enzymes such as chymotrypsin and ribonuclease, it has been proposed that the imidazolyl group of the histidine residue may serve as the basic electron donor, and that the histidine residue in some cases may be the active site of the enzyme. The interactions of L-histidine with heavy metal ions, including Ni (II) (1), Zn (II) (1, …
