Bluebush Seed : Cleaning, Drying And Storing, C V. Malcolm

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

BLUEBUSH (Kochia brevifolia) is a perennial plant which occurs naturally in Western Australia.

In the past it has attracted little attention, but in recent years it has created interest as a highly nutritious and salt tolerant plant well adapted to certain salt affected soils in the wheatbelt.

A previous article (Bulletin No. 2630) by Smith and Malcolm drew attention to its use. One of the problems in establishing bluebush is to obtain seed supplies.

The Control Of Grasses With Chemicals, G R W Meadly

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

GRASSES are among man's greatest assets and usually he tries to encourage their growth.

The cereals, rice and many other grasses supply him with basic items of food and they are also important components of pastures which provide grazing for sheep and cattle.

Orchard Drainage, R G. Cahill

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

UNDERGROUND drainage of orchard land is an essential feature of fruitgrowing which is overlooked by many orchardists.

Soils should be adequately drained to cope with all winter rains.

Natural Paddocks Help Soil Conservation, G W. Spencer

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

ON most farms, particularly in the cereal and sheep districts, the paddocks as we know them are fenced off into neat squares or rectangles.

The original fencing was done in such a way that the paddock layout, as well as the fences, completely disregards the topography or natural features of the land. Often this has encouraged soil erosion.

In properly laid out paddocks there should be a very close relationship between the natural features of the farm, the fence plan, and soil conservation.

Copper Minerals For Fertilizer Use, R N. Glencross

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

COPPER fertilizers have an important role in maintaining: and increasing Western Australia's agricultural production.

On many soils they are essential for cereal growing or pasture production and persistence and for animal health and wool quality.

They are also sometimes used for fruit trees, vines, and vegetables.

Thirsty Cows Are Poor Milkers, S R. Dunstan

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

THE HOT summer weather is not far away, and now is a good time for the whole milk producer to attend to those points which will ensure that milk production is maintained at a high level during this period.

Correcting Cobalt Deficiency, Laurence C. Snook

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

COBALT is essential in the food eaten by sheep and cattle. As little as one part of cobalt in 10,000,000 parts of food appears to be adequate.

But if this mere trace is missing, ruminants will waste away and die, even when the feed appears excellent In every other way.

Establishing Saltland Pastures, C V. Malcolm

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

WITH the approach of winter, thoughts are turning to the seeding season. It will therefore be appropriate to discuss methods of establishing saltland pastures.

This discussion will be restricted to "bluebush," creeping saltbush, and old man saltbush. Seed of these plants is available from local stock firms.

Automatic Waterers For Day Old Chickens, P Smetana, W. Ward

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

ONE of the most tedious and time consuming tasks on a poultry farm is the provision of water to chicks from day old up to the age of three or four weeks.

Most poultry farmers use half-gallon glass fonts with metal bases for the first few weeks, until the chicks are old enough to use the automatic watering system usually situated along one wall of the brooder house.

This cumbersome glass font system can be replaced by the cheap and easily installed automatic watering system described below. This system has already been adopted by several local poultry farmers.

The Use Of Lime In Market Gardens, Department Of Agriculture, Western Australia

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

THE term "lime" when used in relation to agriculture means any calcium containing material that is capable of correcting soil acidity.

While generally used for this purpose, lime has many other equally important functions in the soil.

Construction And Calibration Of Equipment For Obtaining Heat Capacity Data At High Temperatures, David Wells Wood

University of the Pacific Theses and Dissertations

This is a study of the heat capacity substances at high temperatures at determined by means of drop-calorimetry. The heat capacity may be defined as the quantity of heat required to raise the temperature of a substance by 1^o C. This can be expressed as [see PDF file for formula]. The concept of heat capacity is used in connection with a certain defined path such as those of constant volume or constant pressure. The following definitions apply: [see PDF file for formula] = heat capacity at constant volume and [see PDF file for formula] = heat capacity at constant …

Cosmology And Galactic Angular Momenta, Marmion Michael Richard Hays

University of the Pacific Theses and Dissertations

The plan of this paper is to present some observations and then in subsequent chapters to examine the two basic cosmological ideas in the light of these observations.

The first of the observations involves an estimate of the angular momentum in a given volume of space and the ratio of this momentum to the mass or number of nucleons in the given volume. We therefore wish to obtain a rough estimate of the angular momentum in that part of the universe which man may call his immediate surroundings, i.e., the solar system and galaxy.

Coordination Of 2, 8- Bishydroxymethyl - 2, Elements Of The First Transition Series, Charles Edward O'Rear

Master's Theses

The preparation and study of 2, 8-bishydroxymethyl-2, 8-dimethyl-3, 7-diaza-1,5,9-nonanetriol with ions of the first transition series have been investigated. Spectrophotometric studies of solutions of this compound with Cu(II) and Ni(II) ions gave evidence of the formation of complexes containing one mole of ligand per metal ion throughout a wide pH range. The Cu(II) complex, the yellow colored Fe(III) complex formed at high pH, and the light blue colored Ni(II) complex have remained stable over several months. The red colored Ni(II) complex changes slowly into a more stable greenish-yellow complex. The ligand formed weaker complexes with Co(II) and Mn(II). Data from …

An Investigation Of The Analysis Of Turpentine By Gas Chromatography, John R. Wagner

Master's Theses

The development of gas chromatography and the publication of data on terpene analysis by this method has lead to this attempt to analyze turpentine by gas chromatography. The work has been limited to Gum Spirits of Turpentine and Steam Distilled Wood Turpentine since these are of chief importance and are the only types commonly retailed in small packages.

There have been three objectives:

1. To develop a method based on gas chromatography for distinguishing between Steam Distilled Wood Turpentine and Gum Spirits of Turpentine, and detection of mixtures and adulteration.

2. To identify as many components of the two turpentines …

Determination Of Minimum Lethal Level Of Toxaphene As A Piscicide In Lakes Of North Dakota, Dale L. Henegar

Electronic Theses and Dissertations

Toxaphene as a piscicide for localized field application has not been widely used because minimum lethal concentrations have not been in the field. There is, however, considerable information gained from laboratory bio-assay studies (Surber, 1498; Duedoreff, et al. 1953; Hooper and Grzenda, 1955, et al. 1959). Concentrations indicated by such studies are not necessarily correct for field use. Prevost (1960) pointed out that results from controlled laboratory experiments do not always yield dosages exhibiting similar results in the field where a number of variables, both known and unknown, exist over which the field worker has little or no control. Gebhards …

Minor Elements Can Be Overdone, L T. Jones

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

T H E term "minor elements" which is now commonly used and well understood by farmers and gardeners, refers to the five essential plant foods—copper, zinc, manganese, molybdenum and boron.

These five essential plant foods are needed by all plants in minute quantities and it is relatively easy to use them in excess of actual requirements or even in toxic amounts.

In practice this is not usually a problem with cereals and pastures. The important exception is when zinc alone is added to a cereal crop low in copper and the extra zinc accentuates the copper deficiency, and poorer yields …

Evaluation Of The Force Constants Of Non-Polar Gases From Viscosity Data, Kei-Sin Wei

Masters Theses

"The analytical expressions for the transport coefficients (i.e. viscosity, thermal conductivity, and diffusivity) of an ideal gas can be derived from the kinetic theory of gases. It is also possible to make these analytical expressions adequate for real gases if the intermolecular forces of attraction and repulsion for these gases have been taken into consideration.

The intermolecular forces have been studied by many investigators. The Lennard-Jones potential is one of the most realistic semi-empirical statements which represents particularly the intermolecular forces of attraction and repulsion for non-polar gases.

The values of the Lennard-Jones potential parameters or the force constants of …

Geology Of The East-Central Portion Of The Nelson Quadrangle, Clark County, Nevada, Tedral Kantor

Masters Theses

"The purpose of this investigation was to determine the unusually complex geology of a little-known area south of the Eldorado mining district, southern Clark County, Nevada. The area, mapped at a scale of 1:24000, comprises a segment of the northerly-trending Eldorado mountains in the southeast corner of the Great Basin. This rugged desert area is on a drainage divide between the Great Basin and the Colorado River. The rocks of the area consist of Precambrian gneisses and schists invaded by successive generations of Upper Cretaceous (?) - Tertiary igneous rocks. The older rocks, mainly biotite-chlorite gneisses, have resulted from high-grade …

Analysis Of The A3(X3)3 Nuclear Spin System And -Electron Coupled Hyperfine Splitting Constants In Aromatic Hydrocarbons, Juana Acrivos

Faculty Publications, Chemistry

The nuclear spin functions for the A3(X3)3 system have been developed and used to analyse the NMR spectra of (CH3)3C6H3 and (CF3)3C6H3. The π-electron coupled hyperfine splitting constants, obtained from the Ramsey theory with simple Hückel M.O.'s for benzene and without the assumption of an average energy of excitation for the virtual processes which give rise to the coupling, are in agreement with the hyperfine constants observed between the methyl groups and the ring protons in the above compounds.

A Rational Approach To The Estimation Of Evaporation And Evapotranspiration From Climatological Data, Jerald Emmet Christiansen, B. B. Patil

Reports

Many attempts have been made to derive mathematical expressions relating evaporation and evapotranspiration, or consumptive use, to climatological data. IN the United States, the Blaney-Criddle formula is probably the best known for estimating consumptive use (2 and 3). Blaney (1) has also suggested that this formula is suitable for estimating evaporation as measured with a Weather Bureau pan. Other well known formulas are the Penman formulas (10), the Thornthwaite formula (15) and the Hargreaves formulas (8). Halkias, Beihmeyer and Hendrickson (6) suggest that water requirements of crops can be determined from atmometer data. Lowry and Johnson (() in an early …

Certain Trace Element Distribution In The Searchlight, Nevada Quartz Monzonite, Clark County, Nevada, Jai Nandan Shrivastava

Masters Theses

"The once prosperous gold, silver, copper and lead mines of the Searchlight mining district, Nevada, are situated along the south and western margins of a large quartz monzonite body. This intrudes the Precambrian gneisses and younger lava flows. Associated mineral veins show an eccentric type of zoning around the intrusive.

Seven rock samples of the quartz monzonite representing different parts of the intrusive were analyzed petrographically and spectrographically. Modal analyses and various types of rock alteration were investigated petrographically. Spectrochemical analyses of the rock samples and their major minerals were carried out for certain trace elements. A semi-quantitative method was …
