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.

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.

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.
