A Chemical, Physical, and Biological Investigation of the Total Suspended and Dissolved Substances in Lake Dallas with Emphasis on Sanitation

A Chemical, Physical, and Biological Investigation of the Total Suspended and Dissolved Substances in Lake Dallas with Emphasis on Sanitation

Date: 1942
Creator: Eads, Ewin A.
Description: The purpose of this investigation is to determine the suspended organic matter and the total phosphorus in the waters of Lake Dallas and to evaluate these findings. Since organic matter floating in lakes is largely composed of minute plants, animals, and detritus derived from animals and plants, the fertilizing effect of phosphorus must be considered as an integral part of this problem.

A Comparison of the Achievements of Science and Non-Science Majors Enrolled in General Chemistry at North Texas State College

A Comparison of the Achievements of Science and Non-Science Majors Enrolled in General Chemistry at North Texas State College

Date: 1951
Creator: Brogdon, Billie R.
Description: It is the specific purpose of this investigation to determine the difference, if any, in the amount of practical, everyday chemistry learned by the science majors as opposed to the non-science majors enrolled in general chemistry at the North Texas State College during the school year 1950-1951.

Manufacturer [Sic] of Densified-Refuse Derived Fuel (d-RDF) Pellets and Methods for the Determination of d-RDF Pellet Densities

Manufacturer [Sic] of Densified-Refuse Derived Fuel (d-RDF) Pellets and Methods for the Determination of d-RDF Pellet Densities

Date: December 1986
Creator: Attili, Bassam Saleem
Description: There are 150 million tons of Municipal Solid Waste (MSW) annually produced in the United States, which is approximately equivalent to 150 million barrels of oil. MSW production is inexhaustible, and is increasing on an annual per capita basis of approximately three per cent. After controlling the moisture and adding a binder, the combustible portion of MSW was converted to pellets. The objects of this project were to 1) evaluate the binder, 2) prepare the pellets, and 3) evaluate the pellets with regard to density. The manufacture of pellets was conducted at the Naval Air Station, Jacksonville, Florida. The evaluation of the binders and the pellets was done at North Texas State University (NTSU). There were three procedures for measuring the density. The first, using water displacement, was from the American Society for Testing and Material (ASTM). The second, using wax coating, was also from ASTM. The third, using sharply-cut cylindrical pellets, was developed at NTSU.

A Mineral Analysis of the Henrietta Water Supply

A Mineral Analysis of the Henrietta Water Supply

Date: 1941
Creator: Selvidge, R. F.
Description: The water which supplies the city of Henrietta, Clay County, Texas, is obtained from the Little Wichita River. A concrete dam was built across the river at a point about a mile and a half north of town.

Quantitative Chemical Analysis of the Soils of Erath County, Texas

Quantitative Chemical Analysis of the Soils of Erath County, Texas

Date: June 1938
Creator: Barnes, Benjamin F.
Description: A chemical analysis of representative samples of Windthorst sand, Denton sand, and Denton clay has been made, and this analysis shows that their composition has a strict correlation with respect to their geological origins. The analyses of the different soils have shown the Windthorst sand to be highly deficient in all of the essential elements, whereas the Denton sand is deficient in only one; namely, phosphorus. The analysis of the Denton clay showed it to be highly fertile. From the consideration of the pH and the lime content, it has been determined to some extent what crops will grow in each of the soils.

The Storage of Organic Matter in Bottom Deposits of Lake Dallas

The Storage of Organic Matter in Bottom Deposits of Lake Dallas

Date: 1941
Creator: Williams, Cyrus Paul
Description: The purpose of this investigation is to find which season of the year organic matter increases most in the bottom deposits of Lake Dallas, the reason for the increase, and the amount of organic matter increase from year to year. It is hoped that this study will be beneficial in understanding the conditions in artificial reservoirs.
