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

THOUSANDS of miles of contour banks have been built in Western Australia, and most of this earthmoving has been done by tractor and disc plough* or by road grader.

This article describes the technique recommended for bank construction with the road grader.

Farm Dams In The Wheatbelt, J E. Watson

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

MANY new farm dams are sunk each year in the wheatbelt and much money is spent on them.

With continued development of new land, and increasing stock carrying capacity of older land under legume pastures, the need for more water supplies will continue for a long time.

Firebreaks Without Erosion : Hints To Prevent Firebreak Erosion, Department Of Agriculture, Western Australia

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

AGRICULTURAL fire risks are now greater than they have been in the past and are steadily increasing with the advance of agriculture in Western Australia.

During the past 20 years the area of cleared arable land and the area under crop have more than doubled.

The area of established pasture is four times as great as it was. Pastures and crops are much more productive —and more liable to carry destructive fires than they were.

Developing A State Water Plan Utah's Water Resources--Problems And Needs--A Challenge, Utah Water Research Laboratory

Reports

Of all the natural resources with which Utah has been endowed none is more vital to the social and economic well-being of the people than it water resource. We cannot manufacture water. We have found no acceptable substitute. Not one more drop of water is available for our use today than was available to the pioneers. Yet water uses and water demands have multiplied over the years. Since we can do little to change nature's water allotment to Utah we must learn how to utilize our existing supplies more judiciously. This means devoting increasingly more attention to problems of water …

Crystal Habit Modification Of Sodium Chlorate, Michael R. Keegan

Bachelors Theses and Reports, 1928 - 1970

All single crystals have a particular habit or morphology. The crystal habit refers to the relative degree of development of crystallographic planes into surfaces which make up the external appearance of the single crystal.

In this paper, NaClO3 is used as a parent crystal. Its simple cubic habit is modified to tetrahedral by the use of impurities of SO4=, S2O3=, Cr2O7=, and NO3-. The degree of habit change is studied as a function of impurity concentration and temperature. The problem and phenomena are explained in terms of surface chemistry and thermodynamics.

Physico-Chemical Principles Of Sixteenth Century Metallurgy, Robert E. Johnson

Bachelors Theses and Reports, 1928 - 1970

Following a review of sixteenth century metallurgical literature and a discussion of Gibbs free energy, this thesis discusses thermodynamic considerations of galena (PbS) reduction by iron from a lead assay of this period. The importance of fluxes in this assay is emphasized. The discussion covers both equilibrium and non-equilibrium conditions at 1100 degrees Celsius. Possible substitutes for iron are also covered.

Information from twenty-one small controlled lead assays is correlated with the thermodynamic discussion to determine the purpose of each constituent in the assay.

The Beneficiation Of Titaniferous-Magnetite Sands, Ronald Lloyd Nordwick

Bachelors Theses and Reports, 1928 - 1970

The purpose of this investigation of beneficiation methods is to develop and study possible economic methods for recovering an iron-titanium concentrate of sufficient purity to meet metallurgical requirements for subsequent direct reduction to pig iron and a high titanium slag.

Stress-Corrosion Cracking Of Brass, Paul A. Fossey

Bachelors Theses and Reports, 1928 - 1970

the mechanism of stress-corrosion cracking of brass has been sought for many years. Investigators have proposed many mechanisms, but each of these mechanisms has always had several drawbacks. This paper presents an account of experimental work done in the laboratory on this subject and compares it to the work of previous investigations. It evaluates the mechanisms presented by investigators and shows the failures of these mechanisms. A theory of Nitrogen Embrittlement is presented and an evaluation of this theory with experimental work follows.

An Investigation Of The Sintering Of Iron-Wire Compacts, George L. Vivian

Bachelors Theses and Reports, 1928 - 1970

A study of the sintering of iron has been made by observing the rate of bonding of iron wires wound on iron spools. The specimens were sintered at a constant temperature of 850c in vacuum furnaces capable of producing pressures of 10-5 to 10-4 mm of mercury, and the growth of the bond between wires was observed as a function of time.

It has been concluded that the volume-diffusion mechanism is strongly operating in the sintering of iron at 850c, but in an evacuated system, the evaporation-condensation mechanism also contributes to the sintering process.

Flooding And Salt Problems In The Wheatbelt, Department Of Agriculture, Western Australia

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

VALUABLE land has become salty in parts of the West Australian agricultural areas because most of the surrounding land has been cleared and developed for agriculture.

This salting of a small proportion of the land is part of the price paid for the development of agriculture in this State.

Drainage is not the answer to the wheatbelt flooding and salt land problems.

A more practical approach is to limit runoff from sloping land, and to make good use of salt-affected land by growing salt tolerant perennial pastures on it, says the Soils Division of the Department of Agriculture.
