Some Effects Of Ph, Temperature And Light On The Production Of Zoosporagia In Saprolegnia Parasitica Coker, Philip C. Lee

Master's Theses

Pure cultures of Saprolegnia parasitica Coker were grown under varied conditions of temperature, pH, and light conditions. In liquid medium colonies were spherical with a zonal effect in the distribution of zoosporangia.

Near the limiting extremes of pH and temperature, beaded hyphal tips were found in place of normal sporangia. Teorell Universal buffer in the sporulation water inhibited production of sporangia. The pH minimum was 4.0 - 4.1, optimum 6.3 - 7.4, and maximum 8.o - 8.3. The maximum number of sporangia was produced at 15 C. Between 3.4 and 5 C , a delay in sporulation was noted and …

Integrated Versus Departmentalized Teaching Of Eighth Grade Science At William Cullen Bryant Intermediate School, Wilson Lee Faris

Master's Theses

Scientific achievements in the past few decades have stimulated educators to investigate current content and practices in teaching science at the 8th grade level. Man at the threshold of space has become a reality as a result of achievements in science during the past decade. The most notable achievements have been the orbital space flights. Control of atomic energy, the development of powerful rockets, advancement in radar detection and communication, along with discoveries in space medicine have made it necessary to improve and strengthen the eighth grade science program in order to produce the science personnel needed for continued progress. …

A Survey Of Parasitism In A Population Of Pigeons, Robert Flynn Jochen

Master's Theses

Numerous papers relative to parasites in pigeons can be found in the literature, but information concerning parasitic infections in pigeons of Virginia is scant, and no survey of parasitism has been made. Furthermore, no one survey or parasitism in pigeons of North America has included the incidence of both ectoparasites and endoparasites. Information relative to the incidence of individual parasites or groups of parasites, however, is available in recent literature, as well as information concerning isolated cases of parasitism

The present study was undertaken to (1) determine the nature and extent of parasitism in a population of pigeons in Henrico …

Effects Of Surface Roughness On The Intensity Distribution Of Light Reflected From Aluminum Surfaces, Harvey N. Wingfield

Master's Theses

Only over the past few years have investigations of the intensity distribution of the light reflected from materials been attempted. Most of these investigations have been done by personnel at the National Bureau of Standards on matt surfaces, and acid etched black glass. It should be noted that separate investigations in the two fields, the methods of analysis of a surface's topography and the intensity distribution of reflected light from different materials have been and still are being performed. However, most correlations which exist between a surface's topography and its optical effects such as reflectance, intensity, absorption, and transmission are …

Determinants Of Occurrence And Distribution Of Fungi In Marine Environments, Paul W. Kirk

Master's Theses

Studies ware made of the effects of temperature and nutrient levels on salinity optima for growth and sporulation of Chaotomium Globosum and two marine Pyranomycetes, Torpedospora radiata, and Halosphaeriopais sp. Methods of culture and evaluation of sporulation were also investigated.

Discussion focused on ecological implications of data, in particular, on the probable survival value to a marine-fit fungus or a Phoma pattern mechanism-envolving vegetative and reproductive phases. As the seasons progress, the region where concentrations and proportions or salts are most favorable remains similar to that where vitamin requirements are least and biotic factors are most favorable.

An Improved System Of Cost Control And Budgeting By Product, For A Specialty Paper Mill, Linwood Douglas Hogge

Master's Theses

The large kraft and newsprint mills dominate the paper industry, by the sheer enormity of their size and production. The paper industry is a major growth segment of our nation's industry in all its aspects, however, and the specialty mills and their products continue to grow proportionately with the industry. Fllters, gaskets, and saturated products, once the sole property of leather, rubber and more sophisticated materials, are predominately made of high grade paper products. To further increase their use we must find more and better ways to reduce and control these costs -- It is hoped that we have contributed …

A Study Of The Curcumin Method For Boron Determination, James Edward Hardcastle

Master's Theses

The purpose of the research project, of which this thesis is a partial report, was two fold: first, to develop a method for determining small quantities of boron, and second, to develop a rapid field test for the determination of atmospheric boron. A literature survey revealed that the curcumin method is the most sensitive colorimetric method presently available for boron determination. Also, the curcumin paper test should be readily adapted to the determination of atmospheric boron.

The Impact Of Inflation On Selected Wage And Salary Groups In The Richmond Area, Carl Edward Tucker

Master's Theses

One of the greatest economic problems existing in the United States today is inflation. This problem is magnified because our population is still growing, there are changes taking place in methods of production, and property and wealth are being re-distributed.

Americans continually want more things which are bigger and better and they are willing to go in debt to have them. They want more and bigger automobiles, highways, more services, better schools, and more leisure time. The effective demand sometimes has a way of getting ahead of the capacity to produce. With this demand for goods, prices continue to rise …

A Chromatographic Study Of The Polyphenols In Cured Tobacco, Marvin Dennis Edmonds

Master's Theses

The object of this project was to isolate, separate, and identify the polyphenols in tobacco. Following this, the aim was to develop a method for the quantitative determination of the major polyphenols in tobacco.

Existing methods for the determination of polyphenols in tobacco involve lengthy procedures which are concerned with one or two of the polyphenols rather than the· complete class of compounds. The methods consist of exhaustive extraction procedures, lengthy chromatographic procedures and numerous methods of identification.

Extensive research on the determination of polyphenols by chromatography has been carried out in the field of tobacco and in other fields. …
