Pre-Impoundment Estimations of Nutrient Loading to Ray Roberts Lake and Prediction of Post-Inundation Trophic Status

Description: Excessive nutrient loading of natural and artificial lakes has led, in some systems, to plethoric algal and aquatic macrophyte growth which can result in aesthetic degradation and undesirable tastes and odors. It would be advantageous to have some indication of the potential trophic status of a reservoir before it is filled. An objective of this study was to assess the water quality and nutrient loading potential of the tributaries entering Ray Roberts Lake, a large reservoir located in north central Texas. Samples from a maximum of thirteen sites were collected on the Elm Fork, Trinity River, Isle duBois Creek, and five additional tributaries. Data were also collected during six storms, from atmospheric deposition collectors, and from soil-water microcosms. The relationship between watershed landuse and mean water nutrient concentrations was evaluated. Significant differences will exist between the two major arms of Ray Roberts Lake: Elm Fork, Trinity River and Isle duBois Creek. While the majority of the annual phosphorus and nitrogen load entering both tributaries is coming from overland flow, the proportion is higher in Isle duBois Creek. Point sources in the Elm Fork contribute a larger percentage of the bioavailable phosphorus, which is significantly greater than in Isle duBois Creek. The water quality of Isle duBois Creek, especially nitrogen, is affected to a greater degree by the landuses in its watershed. Predictive regression models made accurate estimations of stream nutrient concentrations in Isle duBois Creek. The entire reservoir, upon reaching equilibrium conditions, will be classified as a eutrophic lake. The Trinity arm, with a higher phosphorus load, will display a higher trophic status. The Isle duBois arm has a lower phosphorus load which will give it a lower trophic status. The long hydraulic residence time of the two arms of the reservoir will remove nutrients upstream of the main body, …

Electricity in Rural Areas of North Texas

Description: "This study shows three things: (1) a precedent for the expenditure of public funds to teach electricity in our public high schools has already been established by the school system in the larger school systems of Texas, (2) the rural families living on electrified farms in the North Texas area want instruction of this type given to the boys and girls in their communities, and (3) both the rural people and the professional people of the North Texas area believe that instruction dealing with the use of electricity and electrical equipment had spread until by 1935 more than twenty-one million homes, about eighty percent of the total in America at that time, were electrified, only eleven American farms out of every 100 had central-station electricity. More than five million American farms lacked electric service. "--leaf 50.

Relative Effectiveness of Two Methods of Teaching Personal Development to Homemaking Girls

Description: The question as to whether to teach personality development as a separate unit or to include it as an integral part of the total homemaking program became a problem which required careful investigation. It became the purpose of this study, therefore, to determine whether more measurable growth in personality is achieved by teaching a special unit in personality than by including such subject matter as an integral part of the homemaking program.

Relation of Pre- and Post-Puberty Anthropometric Measurements and Performance of American Negro and Caucasian Females on the AAHPER Physical Fitness Battery

Description: The problem of this study is to determine the relationship that may exist among the variables of racial status, puberty status, anthropometric measurements, and physical fitness. Particularly of interest are the anthropometric differences that may exist among Negroes and Caucasians and the effect that these differences may have upon physical fitness as measured by the AAHPER Physical Fitness Battery. Differences among racial groups and puberty groups will be determined by analysis of variance technique and relations among anthropometric measures and physical fitness components will be compared and determined by correlational techniques.
