Actino- And Thermo- Response Of Molybdenite In Vacuo With Various Colored Lights, John H. Fulton

Master's Theses or Doctor of Nursing Practice

The purposes of this investigation are to study the reaction of molybdenite cells to light of various colors while in vacuo and at various temperatures. The samples of molybdenite were also subjected to radiant heat in the last part of the experiment, which was undertaken to determine to some extent the amount of thermos-electric effect which was due to thermal radiation in the first part of the investigation.

The Effect Of Alternating Current On The Rectifying Properties Of Metallic Salts In Contact With Metals, William Howard Schumaker

Bachelors’ Theses

However much may be said regarding the advantages of direct current, there is little doubt at present, that from the viewpoint of power generation and transmission, alternating current has considerable advantages over direct current. While such is the case, there is, and probably always will be, a need for direct current. According to our present development, this direct current is indispensable in wireless work, radio, and in the laboratory test shops, where it is necessary to work with very sensitive meters, which are inexpensive and easy enough to secure for direct current measurements, but which necessitates an elaborate and costly …

The Fundamental Theorem Of Algebra, John D. Fitzpatrick

Bachelors’ Theses

Algebra is indeed an interesting and intriguing field of knowledge. Many people fear and dread it, and­ yet what do they fear? Is not algebra a logical se­quence of simple facts based perhaps on a few self-evident truths? If people saw the value of algebra, they would strive more enthusiastically to understand its principles. John Locke has a fitting commentary on those who are unfamiliar with algebra.

Current Efficiency Of The Commercial Chromium Plating Bath, John Kaczmarowski

Bachelors’ Theses

The subject matter of this thesis deals with the character of the chromium plate, the amount of hydrogen liberated at the cathode, the weight of the chromium deposited, and the cathode efficiency.

This investigation was made for the purpose of aiding .further research work to increase the cathode efficiency of the chromium plating bath. If greater efficiency can be obtained, then, chromium, as nickel, can be plated on small articles in rotating barrels.

Substitution Of Hydrofluoric Acid For Sulphuric Acid In Chromium Plating, Leonard Schulze

Bachelors’ Theses

Chromium plating or the electrodeposition of chromium from chromic acid baths has been an accomplished fact for almost a century. However, it has not been until the last few years that considerable attributive information has been published to make the mechanism of the process sufficiently understood to permit its commercial operation.¹ Most of the scientific information published on chromium plating thus far is general there being very little specific information revealed as yet. Material, as shall be referred to occasionally, may be read about its early successful applications stressing the unusual properties, advantages, interests, and activities but very little …

A Volumetric Method Of Chromium Determination With Mercurous Nitrate, Gerald W. Lawton

Bachelors’ Theses

Boncyk in his research on potentiometric titrations, made the observation that apparently mercurous nitrate could be used to titrate chromic acid solution. He used potassium iodide as an outside indicator and found that a slight excess of mercurous nitrate gave a gray precipitate with potassium iodide solution. The precipitate seemed to indicate the end point, or the neutralization of the chromic acid; a slight excess of the mercurous nitrate causing the immediate formation of a gray precipitate. Not knowing the exact normality and purity of the solutions used, he could not ascertain whether the gray was the true end point, …

Studies Of Respiration And Carbohydrate Changes In The Potato At 3 Degrees C And 20 Degrees C, Hermann I. Karl

Bachelors’ Theses

The purpose of this paper was to determine the effect which different factors would have on the respiration and the sugar content of potatoes. It is known that the sugar content of a potato may be increased with the lowering of the temperature. It is also known that with this lowering of temperature the respiration is also lowered. What other factors will effect the respiration and the sugar content of the potato and to what extent is the question to be answered.

Although this problem may seem of little importance because sugar .1e not wanted in a potato, yet the …

Nebraska Tractor Tests

All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary.

All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University.

Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …

A Study Of An Objective Placement Examination For Sectioning College Physics Classes, John Milton Willson

Masters Theses

"For several years the Department of Physics of the Missouri School of Mines has practiced sectioning of its classes in general physics. The aim has been to segregate in one section the students of superior ability, giving them a course including both the fundamentals of physics and their applications in engineering. The remainder are given a course in fundamentals without placing so much stress upon the applications...Another criterion used to supplement the first-year grade record is the student's score on the Iowa Placement Examinations. The physics examination consists of two parts, the Training Series and the Aptitude Series. These examinations …

Oxygen is the first immediate necessity of life and water is second. Both directly and indirectly and more than soil, water is our most basic resource. It is the universal solvent and without it there would be no life, and, of course, no agriculture and industry.
