Sediment Movement In Bear River, Utah, Calvin Geary Clyde

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the northern part of Cache Valley, Utah, accelerated erosion in recent decades has cut deep gullies of impressive size into the flat, irrigated bench land along the Bear River. Millions of tons of fine sediment have been washed into the river and great amounts have been deposited in the river bed. The resulting flooding and high water-table have caused much damage to the land near the river.

Fm 30-16, Technical Intelligence, 29 June 1953, Robert Bolin , Depositor

United States Department of Defense Military Intelligence

This is the first US Army manual on technical intelligence. The concept of technical intelligence developed during World War II. Technical intelligence doctrine was formalized by a series of army training circulars and other directives. Toward the end of WWII a new army Field Manual 30-15, Examination of Enemy Personnel, Repatriates, Civilians, Documents, and Materiel (June 1954) was issued, but that manual did not reflect the World War II technical intelligence experience or actual army practices. That manual was superceded by Field Manual 30-15, Examination of Personnel and Documents, 27 September 1951 and by this manual.

This manual defines technical …

The Effect Of Surface Tension Upon The Flow Of Fluids Through Packed Beds, William Charles Streib May 1953

The Effect Of Surface Tension Upon The Flow Of Fluids Through Packed Beds, William Charles Streib

Theses

Flow tests through beds of unconsolidated sand, glass beads and 1/4 inch Berl saddles showed that wide variations in the surface tension of a fluid had no significant effect on its flowrate through the bed. Viscosity and density were the only fluid properties affecting such flow. Excellent comparative results were observed between the flowrates through sand beds and those predicted by the Leva equation.

The complex Brownell and Katz equation for predicting the residual saturation of a packed bed was found to apply for fluids having a much wider range of surface tension than those originally used to derive their …


The Development Of Executives, Joseph Ralph Messineo May 1953

Correlation Of The Number Of Theoretical Plates Vs. Reflux Ratio, George Ignatius Parisi May 1953

Correlation Of The Number Of Theoretical Plates Vs. Reflux Ratio, George Ignatius Parisi

Theses

A correlation is presented from which the number of theoretical plates for a given separation by distillation can be estimated as a function of the reflux ratio. The effects of relative volatility and feed composition upon such a correlation are also studied. Smoker's (1) equation was used in calculating the data. The results were obtained by varying the several parameters which have to be given for any separa tion desired. These include feed compositions of 0.25, 0.50, and 0.75; relative volatilities of 1.1, 1.2, 1.5, and 2.0; and various reflux ratios. The overhead product and bottoms product compositions were kept …

The Flotation Concentration Of A Complex Low-Grade Lead Zinc Ore, Edward James Fong May 1953

The Flotation Concentration Of A Complex Low-Grade Lead Zinc Ore, Edward James Fong

Bachelors Theses and Reports, 1928 - 1970

This report is concerned primarily with the beneficiation of a low-grade complex lead-zinc ore. The depletion of high grade veins has caused the mineral engineer to seek deposits deeper in the earth's crust or to find lower grade deposits. The other alternative has placed more research problems on Mineral Dressing Engineers in particularly the iron, copper, lead and zinc fields.
