Quasilattice Interpretation Of The Thermodynamic Properties Of Mixing Of Binary Alkali-Metal Systems, J. Bevan Ott, J. Rex Goates
Quasilattice Interpretation Of The Thermodynamic Properties Of Mixing Of Binary Alkali-Metal Systems, J. Bevan Ott, J. Rex Goates
Faculty Publications
Quasilattice theory was applied to heats of mixing in the six systems formed from the binary combinations of Na, K, Rb, and Cs. The alkali-metal systems are particularly well suited for a critical test of the quasi-crystalline assumption since the theoretical model for these systems is relatively simple and the thermodynamic data are fairly complex. Very good fits of the heat-of-mixing data were achieved by assuming that the larger atom in the binary system covered multiple sites on the quasilattice. The values of the empirically determined constants appear to fit the physical significance accorded to them by the quasilattice model. …

The Agricultural Potential Of Owingup Swamp. 1. Soil Survey Of Owingup Swamp. 2. Comparison Of Owingup And Grasmere Swamps, L T. Jones, C V. Malcolm, James P. Fallon, Department Of Agriculture And Food, Western Australia
Technical Bulletins
The two swamps, Owingup and Grasmere are practically identical with regard to soil conditions. Grasmere swamp however has been cleared and used for agriculture for some 60 years while Owingup swamp is as yet unalientated. Soils on both swamps consist of mainly organic diatomaceous clay. Findings of the survey indicate that some 2000 acres at Owingup swamp would be suitable for vegetable growing following clearing and draining.

Time Of Application Of Solid Nitrogen Fertilisers., M G. Mason
Experimental Summaries - Plant Research
The current recommendations for time of application of soild nitrogen fertilisers such as urea, ammonium nitrate and sulphate of ammonia are:
Zone A: These fertilisers should be applied as close to seeding as possible.
Zone B: As for zone A except on very sandy soils which are very prone to leaching, where application can be delayed 2-3 weeks.
Zone C: Applications should be delayed about 3 weeks after seeding.

Trial: 69WH4
Aim of Trial : to follow the movement of nitrogen in the soil and to follow the chemical changes of the nitrogen applied as N-P compound 24 :24, urea and ammonium nitrate. Also to follow the pattern of uptake of this nitrogen by the plants. To compare the effects of these fertilisers on the yields of wheat and to relate differences to changes in the nitrogen fractions in the soil and to nitrogen and phosphorus in the plants.

No meaningful conclusions can be drawn until the multiple regression analysis comparing soil and plant parameters with level of response has been completed. Similarly it is extremely dangerious to extrapolate results obtained from any one experiement in a particular district to the general farm situation. In addition these results represent only 1 rather atypical season and so need to be verified by additional calibration trials. in 1973 (40) and 1974 (20).

Ammonium Nitrate Vs Urea, M G. Mason
Ammonium Nitrate Vs Urea, M G. Mason
Experimental Summaries - Plant Research
Ammonium nitrate is a source of nitrogen containing half
its nitrogen in the ammonium form and half in the nitrate form.
Some properties are set out in comparison with urea in the
following table.
Ammonium nitrate has an advantage over urea in that it can
be topdressed onto the surface of the soil and left uncovered
without a danger of loss of nitrogen to the atmosphere. When urea
is left uncovered on the surface of the soil losses of nitrogen occur
through volatilisation of ammonia during the hydrolysis of the urea.
Such losses with ammonium nitrate are only likely to …

The Effect Of A Large Reservoir On Local Government Revenue And Expenditure, Clyde T. Bates
The Effect Of A Large Reservoir On Local Government Revenue And Expenditure, Clyde T. Bates
KWRRI Research Reports
Development of a large multi-purpose reservoir within the area of their jurisdiction may affect property ta.x revenue and expenditure of county governments and school districts. Privately owned land sold to a federally sponsored reservoir is not subject to property taxes because of the doctrine of intergovernmental immunity. Local officials often assume that this loss of assessment will reduce their tax revenue and thereby their fiscal ability to provide an acceptable level of government services. They may also expect the influx of construction workers or the disruption of existing facilities to increase the cost of providing these services. The study approaches …

Continuous Cropping Trials, M G. Mason
Experimental Summaries - Plant Research
The aims of the trials at Binnu, Chapman, Wongan Hills, Avondale and Merredin were:
- To determine whether the application of nitgrogen and fertilisers can maintain yields under a "continuous cropping" system
- To compare the merits of three sources of nitrogen for this purpose.
- To determine the maintenance dressing of superphosphate under this system and the need for supplementary fertilisers.
Trial 61A2
There have been no great problems with this trial. for a number of years the plots have required chemical spraying to control wild oats which had built up. In 1968 and 1969 some plots were soil sampled to determine …

Nitrogen Use On First Crops After Legume Pasture, M G. Mason
Experimental Summaries - Plant Research
Apart from the normal factors affecting response of cereals to nitrogen fertilizers, i.e. length of growing season, rainfall, soil type etc, there are other factors which affect the response after a legume pasture. these factors include length of the previous legume phase and how good was the stand of legumes. Unfortunately for most of the trials in the past, involving the use of nitrogen on first crops after legumes, this information is not available.

History Of The State Vermin Barrier Fences, Formerly Known As Rabbit Proof Fences, J S. Crawford
Research Reports
There is evidence of rabbits arriving in Australia as far back as 1788, and it is well known that others were liberated on islands around the coast, including some off the coast of Western Australia. However, they remained localised and it is now generally accepted that the rabbits which did spread originated from a small shipment of the wild type brought on the Clipper “Lightning” in 1859. They were released on “Barwon Park”, the property of Thomas Austin, near Geelong in Victoria, and within three years, had reached pest proportions

A New Rhinoceros From The Nebraska Miocene, Lloyd G. Tanner
A New Rhinoceros From The Nebraska Miocene, Lloyd G. Tanner
Bulletin of the University of Nebraska State Museum
A new species of rhinoceros, Menoceras marslandensis, is here proposed. It is based upon a nearly complete skull from the upper part of the Marsland Formation, Hemingford Group (Miocene), of Box Butte County, Nebraska. The new species was probably derived from Menoceras arikarense (Barbour), collected from the Agate Springs Quarries (Arikaree Group, Harrison Formation) of Sioux County, Nebraska, with which both Diceratherium niobrarensis Peterson and D. cooki Peterson are likely synonymous. From Menoceras arikarense, the presumed ancestral stock, Menoceras marslandensis differs in possessing the following characters: (1) very long, fused but slightly cleft, nasals, with flattened, rugose areas …
