Factors Involved in Passive Transfer of Contact Hypersensitivity

Factors Involved in Passive Transfer of Contact Hypersensitivity

Date: August 1966
Creator: Ellis, Walter L.
Description: Delayed hypersensitivity can be conferred passively to normal animals. There exists a period when whole peritoneal exudate cells will passively confer delayed sensitivity, but a sonic extract from them will not; however, after a few more days, both whole cells and sonic extracts could transfer sensitivity. This investigation was undertaken to study the differences in cells collected at two different time intervals after initial sensitization of guinea pigs with 1-fluoro-2,4-dinitrobenzene.

Factors Involved in the Antibiotic Sensitivity of Staphylococcus Aureus

Factors Involved in the Antibiotic Sensitivity of Staphylococcus Aureus

Date: June 1961
Creator: Rotter, Joan
Description: It was the purpose of the present investigation to determine if sensitivity to other antibiotics can likewise be affected by subjecting S. aureus to heparin contact. It is of special interest in this problem to determine whether heparin in some manner affects the combining process of penicillin with the cells of several strains of S. aureus.

The Fecundity of the Bluegill (Lepomis Macrochirus) in Certain Small East Texas Reservoirs

The Fecundity of the Bluegill (Lepomis Macrochirus) in Certain Small East Texas Reservoirs

Date: 1949
Creator: Estes, Charles M.
Description: A study of reproduction and spawning habits of the bluegill in a particular lake must include adequate samples for each period of the year. This will make it possible to determine the number of eggs in each spawn and the frequency of spawning. The number of spawns and average egg production for various sized fish shows the pattern of activity and makes possible further basic research.

Food Habit Analysis of the Two Species of Texas Crappie

Food Habit Analysis of the Two Species of Texas Crappie

Date: 1941
Creator: Mitchell Glenn C.
Description: This study is based upon information taken from stomach analysis of 302 black crappie and 561 white crappie; the following data will be presented: 1. Food of adults and fingerlings; 2. Diet variation in relation to food availability; 3. Seasonal variation of feeding habits; 4. Diet variation in relation to size of crappie. Collections were made from ten lakes located in North, East, Central, and South Texas.

Food Habits and Dietary Overlap of Four Species of Rodents from the Mesquite Plains of Texas

Food Habits and Dietary Overlap of Four Species of Rodents from the Mesquite Plains of Texas

Date: May 1972
Creator: Alcoze, Thomas M.
Description: The coexistence of Dipodomys ordii and Perognathus hispidus with Peromyscus maniculatus and Reithrodontomys montanus was studied in a grassland association of central Texas. The food habits of these species were compared with information from habitat vegetation analysis in an effort to determine food selectivity and the amount and importance of niche overlap and competition among these rodents.

A Gas Chromatographic Study of Actinomycete Tastes and Odors

A Gas Chromatographic Study of Actinomycete Tastes and Odors

Date: August 1966
Creator: Hendricks, Albert C.
Description: The primary purpose of this study was to continue the search for a suitable liquid phase which could be utilized in a gas chromatographic study of actinomycetic tastes and odors. Of equal importance were the attempts to characterize the compounds found in the odor water.

General Biology Lecture and Laboratory Curriculum Outline in a Two or Four-Year College

General Biology Lecture and Laboratory Curriculum Outline in a Two or Four-Year College

Access: Use of this item is restricted to the UNT Community.
Date: August 2000
Creator: Moreland, Amy L.
Description: In July of 1999, I wrote to 24 Texas junior and community colleges (and one four-year institution) describing my thesis agenda of a general biology lecture and laboratory syllabus for introductory biology students. I requested the titles and authors of the general biology textbooks and laboratory manuals they were currently using, the publishers of these texts, and the edition of said texts. I then contacted publishers of the various textbooks who, in turn, directed me to the Dallas-area representatives for further inquiries. I assimilated the various authors' general biology topics into a two-semester syllabus of lecture and one semester of laboratory. The document is not a text manuscript, but an all-inclusive listing of a general biology syllabus broken down by subject.

Geographic Variation in Chromosomes and Morphology of Peromyscus Maniculatus in Texas and Oklahoma

Geographic Variation in Chromosomes and Morphology of Peromyscus Maniculatus in Texas and Oklahoma

Date: August 1972
Creator: Caire, William, 1946-
Description: This study was initiated after finding two chromosomal types of Peromyscus maniculatus north and south of the Red River in Texas and Oklahoma. The problem was to explain the chromosomal variations and their implications to the systematics of the grassland subspecies of P. maniculatus in this region.

A geospatial tool for assessing potential wildland fire risk in central Texas.

A geospatial tool for assessing potential wildland fire risk in central Texas.

Date: August 2005
Creator: Hunter, Bruce Allan
Description: Wildland fires in the United States are not always confined to wilderness areas. The growth of population centers and housing developments in wilderness areas has blurred the boundaries between rural and urban. This merger of human development and natural landscape is known in the wildland fire community as the wildland urban interface or WUI, and it is within this interface that many wildland fires increasingly occur. As wildland fire intrusions in the WUI increase so too does the need for tools to assess potential impact to valuable assets contained within the interface. This study presents a methodology that combines real-time weather data, a wildland fire behavior model, satellite remote sensing and geospatial data in a geographic information system to assess potential risk to human developments and natural resources within the Austin metropolitan area and surrounding ten counties of central, Texas. The methodology uses readily available digital databases and satellite images within Texas, in combination with an industry standard fire behavior model to assist emergency and natural resource managers assess potential impacts from wildland fire. Results of the study will promote prevention of WUI fire disasters, facilitate watershed and habitat protection, and help direct efforts in post wildland fire mitigation and ...

A Grassland Evaluation of Eastland County, Texas

A Grassland Evaluation of Eastland County, Texas

Date: 1951
Creator: Durham, Norman Nevill
Description: This investigation has had for its purpose the determination of first, all members of the Gramineae (Grass) family found in the county; second, the incidence of each species with the various types of soil; third, the grazing value of each species; fourth, the life span of the parent plants; fifth, the present grassland status; and sixth, the potentialities of developing desirable grassland.
