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 zoo sporangia. 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 8.0 - 8.3. The maximum number of sporangia was produced at 15 C. Between 3.4 and 5 C, a delay in sporulation was …

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.

Determination Of A Molecular Weight Distribution For Intermediate Degradation Products Of Bovine Plasma Albumin, Sherwin M. Beck

Master's Theses

Within the last decade several important studies have been made on the large degradation of products of proteins. However, little work has been done on the intermediate degradation products. This study is concerned with the chromatographic separation of intermediate fragments from chrymotryptie hydrolysates of bovine plasma albumin and the determination of the molecular weights of the fragments. An automatic recording differential refractometer employing a differential cell of original design permitted the observation of chromatographic components as they were eluted f rom a column of Sephadex G-50. A fraction collector of original design collected 3 ml. fractions of the effluent. Three …

The Effects Of Water Deprivation On The Body Weight, Food Intake And Water Intake Of The Albino Rat, Kenneth A. Blick

Master's Theses

A survey of the literature reveals a substantial body of research concerned with the effects of food and/or water deprivation on body weight, food and water intake, and activity of the albino rat. This research is important because many psychological experiments, particularly those studies in the field of animal learning in which motivation is induced by the use of a nutritional maintenance schedule, require some measurement of performance on consecutive days during which the rats are in a motivational state.

A Survey Of The Food Habits And Distribution Of The Fishes Of Tuckahoe Creek, Virginia, With Special Emphasis On Lepomis Macrochirus Rafinesque, David Andrew Flemer

Master's Theses

An integral part of the ecological study of any organism is a good understanding of the food relationships. Basic studies of the distribution and ecology of common fresh-water fishes are necessary before a more detailed analysis can be made of the fishes in a particular area. Lagler (1956) states that food habit studies help determine population levels, rates of growth, and condition of the fishes. He also concludes that they serve as a partial basis for determining the status of various predatory and competing forms. Raney (1942) states that an intelligent fishery management program depends heavily upon information gained through …

Modern Concepts Of Mind And Body In The Light Of The Teaching Of The Bible And The Writings Of Ellen G. White: A Comparative Study, Mabel Klopfenstein Gill

Master's Theses

The purpose of this Study la to compare the conclusions of modern psychology and present-day medical understanding with what has been written by Mrs. Ellen G, White cm the subject of the relation of mind and body. Texts of Scripture and Bible examples will also be used. Much material has cone into existence since the volumes of Mrs, White's writings appeared, yet the principles they portray are as up-to-date and as applicable as those In current literature* This author also points out warnings and dangers which apply to present principles of psychology.

The study of this subject is Important because …

A Critical Study Of The Chromosomes In Two Species Of Myxophyceae, John Thomas Mullins

Master's Theses

The Myxophyoeae or blue-green algae have been frequent subjects for cytological investigation since Schmitz (1879) first called attention to two regions in the protoplast. Since that publication the morphological and chemical nature of the genetic material and the mechanism of cell division in the Myxophyceae has been a controversial subject, The evidence that has been presented is, tor the most part, more voluminous than enlightening.

This investigation was undertaken in order to verify the methods and check the results obtained with the smear technique by Strickland (1948). Additional methods were also applied which might enable a more critical evaluation of …

Observations On The Morphology, Physiology, And Life History Of Allescheria Boydii Shear, Robert Denton Flory

Master's Theses

Of those organisms upon the face of the earth displaying a wide range of variability, excellent examples may be found amoung certain groups of the fungi. This extreme variation as noted in certain fungal groups becomes even more interesting when the phenomenon of sexuality is eliminated or of rare occur­rence as in many of the Fungi Imperfecti. Such extreme varia­tions occur in Allescheria Boydii, whose historical background is as interesting as the growth of the fungus itself.

In 1909 Tarozzi (46)isolated a fungus organism as the causative agent in a Sardinian case of mycetoma. Tarozzi referred this fungus to Saccardo, …

A History Of Virginia In The Spanish-American War, Virginia Rowe Christian

Master's Theses

Half a century ago, on February 15,1898, the United States Battleship Maine was destroyed by a mysterious explosion as she lay peacefully at moorings in Havana Harbor. At the time, the sympathy of the United States citizens lay strongly with revolutionists in Cuba who were then attempting to secure their freedom from the galling yoke of Spanish rule. The episode of the Maine gave added impetus to the trend which was inevitably drawing the United States and Spain into a state of war and the final breach occurred on April 19,1898, when the United States government recognized the independence of …

The Distribution And Ecology Of The Terrestrial Shell-Bearing Mollusca Of Hanover, Henrico, And Chesterfield Counties, Virginia, John Bayard Burch

Master's Theses

Very little has been published concerning the molluscan fauna of Virginia, this being also true for the area under consideration. A preliminary list of the Mollusca of Hanover County was published by J.B.Burch (1952) in which twenty-five species and subspecies of land snails were reported. Several of the land Mollusca of Henrico and Chesterfield Counties were listed by P.R. Burch (1950). These included the snails Discus patulus Deshayes, Haplotrema concavum (Say), Mesodon thyroidus (Say), Stenotrema hirsutum (Say), Triodopsis Fallax (Say), and Ventridens = (zonitoides) arboreus (Say). Two additional species, Helicodiscus parallelus (Say) and Retinella indentata (Say), were reported by personal …

The Treatment Of Animals In Poetry From Pope To Wordsworth, David Kingsley Johnston

Master's Theses

The general topic of the treatment of Nature in poetry has be­come somewhat shopworn . Miss Reynolds' excellent coverage of that transitional period from Pope to Wordsworth has crossed the lending library desk into the hands of students and interested readers many times. Her effort is one of the first to reveal in a scholarly fashion a love or Nature and the manners of its expression.

Myra Reynolds considers all aspects of Nature. She seems to leave no stone of intonation unturned. In stating the paramount characteristics of the treatment of Nature as handled by the classical poets, she notes …
