A Preliminary Study Of The Separation Of The Copper Sulfides From Sphalerite And The Effect Of Certain Reagents On Some Of The Pure Copper Minerals In Synthetic Mixtures, Gailen T. Vandel

Bachelors Theses and Reports, 1928 - 1970

The problem of separating the copper sulfide minerals from sphalerite, in copper - zinc ores, has been a difficult one. This is largely due to the lack of adequate research and the small amount of data obtainable on the behavior of copper and zinc sulfide minerals in flotation circuits.

Wind And Earthquake Stresses In Tall Buildings, Henry A. Reynolds

University of the Pacific Theses and Dissertations

With the increasing cost of land in the modern city it has been necessary to expand upward rather than on the surface. The result has been to concentrate commercial and industrial enterprises in small areas whose influence is felt over the entire world. Notable examples are New York and Chicago. In these developments the engineer has played no small part. It is claimed by some that the maximum economic height has been reached at a thousand feet. However, both the Chrysler and Empire State Buildings have slightly passed this mark. It is not improbable that even taller buildings then these …

Data For Standard Curve Chord Steel Roof Trusses., William Hewitt Bush

Professional Degree Theses

"In the past the Engineering Department of the structural steel company, by which the writer is employed, has been troubled with having to make a large number of preliminary steel truss designs for the purpose of estimating weights for competitive bids on structural steel building contracts. In order to eliminate this expenditure of time, a study was made of the possibility of making a standard design for curved chord steel roof trusses that would give the desired information by observation"--Truss Design, page 5.

The West Side Sewage Treatment Works Of The Sanitary District Of Chicago, John Edwin Mccauley

Professional Degree Theses

"Herein following is a thesis on the West Side Sewage Treatment Works of the Sanitary District of Chicago. I have endeavored to cover a large field in one thesis, but think is giving the material I have, the fundamental points have been covered. The local need of sewage treatment is so involved with county, state, Federal, and even International issues that to write solely of local conditions would be to leave out the main part of the story. So, in writing, I have tried to dover enough of the subject to give the historical facts along with the construction side …

The North Side Sewage Treatment Works Of The Chicago Sanitary District, Floyd Allen Gerard

Professional Degree Theses

"My aim in writing this thesis has been to give a clear and concise picture of the Plant, its construction, operating experiences, results and the need for sewage treatment. For this reason, I have incorporated much information, which, while not dealing directly with the subject in hand, is closely allied to it and forms a very necessary background. As the Sanitary District considers its actual operating results confidential, I have refrained from including them. Much useful information can be derived from a careful study of the photographs and drawings included"--page ii.

A Few Notes From The Sanitary Engineering Field, Ronald Davies Ward

Professional Degree Theses

"This paper, it is felt, may appear to be a somewhat disconnected discussion of a few points that have come to the writer's attention from his limited experience and practice in the field of Sanitary Engineering. It has not been the intention, however, to provide a discussion of continuity which would take the reader from the ground up through the process involved in the design and construction of any particular structure, system, or plant; but rather is it to be considered the writer's attempt - although probably a somewhat feeble one - to set forth in a note-book, as it …

Diversion Of Mississippi Flood Water As Aid To Flood Control, R. W. Campbell

Professional Degree Theses

"For many years the lower Mississippi River valley has been in constant danger from high water causing disastrous floods. The important city of New Orleans, our typical French city, is below the surface of the Mississippi River at all stages, and its only means of protection at present is by a levee. Should this bulkwark give way, the whole of that city would be submerged. With this danger in mind, the writer has undertaken a study for, and design of a spillway above the city to reduce the danger caused by high water. Each year flood heights increase and the …

Drainage And Irrigation Of A Thirty-Six Square Mile Tract Of Land In Louisiana, Ralph Charles Dodge

Bachelors Theses

"Because of the fact that I was unable to secure all of the necessary data concerning the topography of the section in question I made several assumptions. However, these assumptions were not made at random, as the land lies on the coast and is subject to the same conditions as does the southern portion of Jefferson County, Texas, of which I have accurate knowledge and which lies directly across Sabine Pass"--Introduction, page iv.

A Study To Determine The Feasibility Of Irrigating The Lands Included In The Cache Valley Water Conservation District No. 1, I. Donald Jerman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this report is to investigate the feasibility of irrigating the lands of the Cache Valley Water Conservation District No. 1. The district, as it now stands, is very much in need of many improvements. The Main canals are now in use and are in a good condition to serve all the lands with the required amount of water, but the few laterals that are now constructed, are in a poor condition, with the remaining laterals yet to be finished.

Before successful irrigation can be practiced, a large portion of the land will require leveling and small areas …

A Study Of The Flow Of Water Over Triangular Weirs And The Determination Of Coefficients Of Discharge For Small Heads, J. Milton Barrett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The development of artesian and pumped wells as a source of irrigation water has created the need for a measuring device which will be accurate for small discharges. The thin edged weir has been accepted as one of the most accurate and desirable measuring devices for this work. Three types of weirs are now commonly used: the Rectangular, the Cipolleti, and the Triangular Notch weir. Of these types the triangular notch is probably best suited for small discharges (under 3 second feet). The various formulae for discharge over 90% Triangular weirs have been accurately determined for heads over two tenths …

The Analysis Of Stresses And Design Of Multiple-Arch Dam, Guy Robert Scott

Bachelors Theses

"The so-termed: "Multiple", or "Scallop-Arched" dam, as its name implies, is one composed of a series of arches, either semi-circular or segmental in plan. These arches were first vertical but were later inclined downstream, when the engineers recognized the value of the weight of water in increasing the resisting moment. The thrust of these arches, due to the water pressure and the weight of the arch itself, is transmitted directly to the buttresses. There are numerous advantages to this type of dam over that of the gravity type"--Introduction, page 1.

The Movement Of Ground Water And Its Relation To The Drainage Of Irrigated Lands, Ernest O. Larson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One needs but to review the history of the irrigated projects of the West to see clearly the importance of drainage. Since the passing of the Reclamation Act in 1902, the construction of drainage work by the United States Reclamation Service on seventeen projects located in thirteen western states represents about 12 percent of the expenditures from the Reclamation Fund. The portion for drainage has been spent during the last few years. This work has required an annual expenditure of about $1,000,000 or a total of $8,000,000 to July, 1922⁽¹⁾. The work completed is estimated to have reclaimed …
