A Comparative Quantitative Study of the Common Elements Found in the Post Oak and Willow

A Comparative Quantitative Study of the Common Elements Found in the Post Oak and Willow

Date: August 1939
Creator: Clark, James L.
Description: This thesis explores the chemical contents of post oak and willow trees. Samples of each tree are compared to determine the amount of sulfur, phosphorus, potassium, sodium, silicon, iron, aluminum, calcium, magnesium, and manganese in them. Results indicated usefulness of each tree to humans.

A Quantitative Chemical Examination of Surface Well Water from the Three Principal Geological Divisions of Denton County

Date: August 1936
Creator: Schnably, John Robert
Description: A sample of the surface-well water was taken from an area of the predominating soil of each of the three geological regions of Denton County, Texas, and a chemical analysis of each sample was made. This thesis deals with the area from which the samples were taken, the methods of analysis used, and the results of the analysis.

The Rate of Natural Fermentation of Various Solutions with Regard to Temperature

The Rate of Natural Fermentation of Various Solutions with Regard to Temperature

Date: August 1938
Creator: Lambert, Frank E.
Description: The purpose of this study is to investigate the rate of natural fermentation of solutions at different temperatures. Whatever microorganisms that chanced to be present in the air and that chanced to fall into the inoculating medium are the ones which brought about fermentation when transferred to the fermentable solution.

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.

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.
