An Investigation On The Sulfuric Acid Leaching Of Low Grade Rock Phosphate, David Weldon Reed Aug 1938

An Investigation On The Sulfuric Acid Leaching Of Low Grade Rock Phosphate, David Weldon Reed

Masters Theses

[From the Introduction]

The practice or using phosphatic materials as fertilizers goes back so far there is no record of when and where they were first employed. The dung of birds was used over 200 years B.C. The use of bones is also an ancient practice. These materials continued to be the main sources of phosphorus and phosphoric acid until after the middle of the nineteenth century, when the Napoleonic battlefields, which had been a source of bone, could no longer be worked profitably.

The treatment of phosphatic materials with sulfuric acid was first suggested by Liebig in …

The Accuracy Of Pressure Gauges Used On Household Steam Pressure Cookers, Arnold E. Baragar May 1938

The Accuracy Of Pressure Gauges Used On Household Steam Pressure Cookers, Arnold E. Baragar

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

In the pressure cooker, high temperature is obtained by using steam under pressure. Since the pressure gauge is used as the indicator of temperature it is essential that the gauge register the correct pressure. Hence, this paper deals mainly with a study of the accuracy of both new and old pressure gauges used on steam pressure cookers. At the same time, four other phases were investigated: (1) the proper functioning of safety valves, (2) the various methods of sealing the lid to the cooker, (3) the proper evacuation of air from the cooker, and (4) the use of a thermometer …

A Critical Analysis Of Methods Of Securing Basic Irrigation Data Used In Water Right Determinations, A. Alvin Bishop May 1938

A Critical Analysis Of Methods Of Securing Basic Irrigation Data Used In Water Right Determinations, A. Alvin Bishop

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Agriculture in the Western United States is almost entirely dependent upon irrigation. Irrigation has transformed the desert lands into fertile, producing valleys. It has made possible communities and settlement areas which would otherwise be impossible. Although the achievements of irrigation have been great, there still remains millions of acres of fertile land that will never be reclaimed because there is not available water.
