A Chemical Analysis of the Soils of Denton County, Texas

A Chemical Analysis of the Soils of Denton County, Texas

Date: August 1936
Creator: Wilson, Curtis
Description: The purpose of this study was to analyze the different soils in Denton, Texas. For the purpose of this study, the soils of Denton County are divided into three general groups with respect to origin: 1)those formed in place by the weathering of consolidated rocks, 2) those formed from the weathering of unconsolidated rocks, and 3) alluvial soils. A chemical analysis of representative samples of Bell Clay, Kirvin fine sandy loam, and San Saba clay has been made, and shown to have a strict correlation with their respective geological origins.

A Comparative Study of Errors in Chemistry and English Found in Examination Papers of Freshman Chemistry

A Comparative Study of Errors in Chemistry and English Found in Examination Papers of Freshman Chemistry

Date: August 1938
Creator: Phillips, Annie
Description: This study attempts to discover what types of errors are commonly made by students in freshman chemistry classes. It considers the errors resulting from the students' lack of knowledge of the subject taught, and errors attributed to their failure to use correct English in their expression of ideas.

Determination of Nitrogen, Phosphorus, and Potassium in Various Plants

Determination of Nitrogen, Phosphorus, and Potassium in Various Plants

Date: August 1938
Creator: Holloway, J. B. Menlo
Description: This study attempted to form some conception, through the analysis of a representative group of plants in the vicinity of Denton, of the amount of the three essential elements in the leaves as compared with the amount in the woody portions. The comparison of leaf with stem as to the quantity of nitrogen, phosphorus, and potassium is explained.

Mercury-Sensitized Photochemical Action on a Mixture of Isobutane and Isobutene

Mercury-Sensitized Photochemical Action on a Mixture of Isobutane and Isobutene

Date: June 1939
Creator: Gary, Felice
Description: This study investigated mercury-sensitized photochemical action on a mixture of isobutane and isobutene. Flow runs of isobutane-isobutene 3.2.1 mercury-saturated gases illuminated with unfiltered radiation of mercury vapor lamp gave no detectable change to hydrocarbons heavier than C4 at reaction tempratures of 27C. and 99C.

Molecular Dimensions

Molecular Dimensions

Date: August 1938
Creator: Moss, H. H.
Description: This study attempts to calculate the areas of the cross section and diameter of the CH3 group, COOH group, the length of the carbon chain, and the longtiudinal distance between carbon atoms for each of the three acids. It also attempts to develop a method of measuring the effective diameter of molecules of gases. Equations for these terms as given by MacDougall and experiments were performed and the data applied to the equation.

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.
