Critical Masses Of Oralloy Cylinders With Multiple Reflectors Of Medium Z Elements, David P. Wood

Mechanical Engineering ETDs

Critical mass is influenced mainly by the density, concentration, and shape of the fissionable material, the degree of neutron moderation, and the type and thickness of reflector material. Most of these parameters have been explored in detail at the Pajarito Remote-Control Laboratory (1) and the present series of measurements has the purpose of investigating reflector materials in the middle of the periodic table for the more subtle influence of their resonance scattering structure.

Behavior Change Through Training, Robert Walter Messerschmidt

Theses

This thesis represents an investigation of attitude and behavior change as a result of human relations training, The elements of heredity and environment are proffered as a basis for attitude and behavior formation. It is denoted that these elements are also instrumental in subsequent development of adult behavior.

As noted in the literature, the term "individual differences" embodies the effect of virtually unique heredity and environmental conditions to which each person is exposed. These differences are also partly determined by the growth in developmental trends, which varies from individual to individual and from time to time.

The existence of individual …

Tractor Testing In Australia. Part 2, G H. Vasey, W. F. Baillie

Journal of the Department of Agriculture, Western Australia, Series 4

AUSTRALIAN test procedures, though differing: in some details, and in some ways going further and telling more about the tractor, conform in essentials to overseas standards.

The tests are in four main parts—

(a) the physical properties of the tractor;

(b) the power of the engine, and its stationary outlets—the belt and the p.t.o;

(c) the power on the drawbar when working on a formalised test surface or track;

(d) the reliability of the tractor when running under test, and its condition after the test.

The Status Of Gas-Lubricated Bearings, Bhaskar Dattatraya Shiwalkar

Masters Theses

"The idea of gas-lubricated bearings was suggested as far back as 1854 by Hirn, but it is only very recently that they have aroused a great amount of interest. The interest is centered on the advantages of gas-bearings for the following major applications:

1. High temperature lubrication where ordinary liquid or grease lubrication fails.
2. Bearings operating in radio-active atmospheres where conventional lubrication may break down.
3. Applications sensitive to contamination where fouling from lubricating oil becomes serious.
4. Low-friction devices--an especially important advantage because of the trend to high speed machinery.
5. Applications where positional accuracies down to micro-inches are required.

As a result …

Critical Load For A Rectangular Plate Simply Supported On Three Edges, Built In On The Fourth Edge, And Compressed On Two Opposite Simply Supported Edges By A Load In The Plane Of The Plate, Bert Louis Smith

Masters Theses

"There are many engineering structures in which thin plates are used extensively, some examples of which can be found in ship and airplane structures, bridges, etc. The problem contained in this thesis is the analysis of a thin rectangular plate simply supported on three edges, built in on the fourth edge, and compressed on two opposite simply supported edges by a load in the plane or the plate. This problem becomes one of stability, and the object of the solution is to find the smallest load that will cause the plate to buckle"--Introduction, page vi.

The Burnett Control Gate For Irrigation Channels, B Swan

Journal of the Department of Agriculture, Western Australia, Series 4

THIS type of check-gate for use in irrigation ditches, was evolved on the Kimberley Research Station and has definite advantages over wooden or concrete structures in that it is termite-proof and can be removed and replaced in a few minutes to permit of the channel being cleaned out by straight runs with modern machinery.

Tractor Testing In Australia, G H. Vasey, W. F. Baillie

Journal of the Department of Agriculture, Western Australia, Series 4

AUSTRALIA is one of several countries that have set up "official" tractor testing schemes.

These schemes mean testing stations that, while providing a testing service for both the manufacturing industry and the consumer, in effect mainly the farming industries, are independent of either.

Effect Of Boundry Layer Control, Through Surface Holes, On The Film Coefficient Of Convective Heat Transfer, Jainti Prasad

Masters Theses

"This thesis has as its objective, the effect of some boundary layer control on the convective heat transfer film coefficient, metal to liquid. The boundary layer control was produced by drilling 1/16 inch diameter holes on the tube surface.

In this modern world of atoms and the current development of large quantities of its energy at low cost, the subject of designing heat exchange devices of higher efficiency is receiving considerable attention. In a reactor, or any type of heat exchange device, there are limits for the temperatures of a heat exchange surface because of corrosion, strength of metals etc. …
