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

TRIALS at the Badgingarra Research Station have indicated that many pasture species will grow in the West Midlands area.

Choice of the species most suited to any particular locality will be influenced by soil type, rainfall, grazing characteristics and possible ill-effects on stock.

The following species have been recommended.

Chemical Thinning Of Plums And Peaches, J E L Cripps, K. T. Whitely

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

DURING the past decade the acreage of Japanese plums in Western Australia has increased by 10 percent, and production has risen by nearly 40 per cent.

Furthermore, almost 30 per cent, of our trees were still classified as non bearing in 1966, so rapid increases in production are certain to be recorded within the next few years.

Renin Granularity In The Mouse Kidney, R. Williams Soller

Senior Scholar Papers

Briefly. the rennin-angiotensin-aldosterone triangle can be thou ht of as a regulator of renal perfusion. Renin, released by the kidney in response to any threat in its perfusion n, acts on its substrate to produce angiotensin I, a mild vasoconstrictor which by means of plasma converting enzymes secretes angiotensint II. This latter product not only stimulates aldosterone output by the adrenals, but also supports the animals’ blood pressure. With aldosterone binding at the distal tubules in the kidney and this causing increased sodium retention, restoration of renal perfusion occurs – a phenomenon which shuts off the original signal for rennin …

A Brief History Of The Namru-3 Medical Zoology Program, Harry Hoogstraal

United States Naval Medical Research Unit 3: Publications

The NAMRU-3 Medical Zoology program began during Easter week of 1950. We had just closed the NAMRU-3 field station at Torit, in Equatoria Province of soulheastern Sudan, and were heading homeward to the United States. However, the offer to remain in Egypt for a year or two to develop a Medical Zoology department at NAMRU-3 provided an interesting challenge after working for several years in tropical forests and grasslands of Africa and other continents. We shall briefly describe subsequent events under four headings: (1) Medical Zoology in Egypt, (2) Ticks and Tickborne Diseases of the World, (3) Kala Azar in …

The Hydroxamate Reaction Of Aminoacyl-Trna Synthetases, David Ian Hirsch

Student Theses and Dissertations

Amino acids are activated as aminoacyladenylates which remain bound to the aminoacyl-tRNA synthetases that catalyze their formation. The activated amino acids are then esterified to specific transfer RNA molecules. By this reaction sequence, the specificity and energetics necessary for polypeptide synthesis are conferred upon the amino acids. The first method of determining acyl group activation was the hydroxamate assay. The activated amino acids can be trapped as the stable amino acid hydroxamates by carrying out the activation reactions in high concentrations of hydroxylamine. This thesis comprises a study of the hydroxamate reaction of the aminoacyl-tRNA synthetases. Each of fourteen partially …

Phosphoproteins Of The Cell Nucleus: Metabolism And Characterization, Lewis Joel Kleinsmith

Student Theses and Dissertations

This thesis is concerned with the chemistry and metabolism of the phosphorylated proteins which are found localized in cell nuclei. The studies focus first on phosphoprotein metabolism as it occurs in the intact nucleus under varying conditions, and then on the chemistry and enzymology of a phosphoprotein fraction which has been extracted and purified from isolated nuclei. The metabolism of phosphoproteins was studied in isolated calf thymus nuclei employing P³²-orthophosphate as a tracer. These isolated nuclei incorporate this isotope into nuclear proteins, which yield phosphoserine and phosphothreonine on hydrolysis. Protein phosphorylation is energy dependent, and occurs after the …

The Structure And Replication Of A Parainfluenza Virus, Richard W. Compans

Student Theses and Dissertations

The simian parainfluenza virus SV5 is a member of myxovirus subgroup II, which includes parainfluenza, mumps, and Newcastle disease viruses. These viruses are 120-500 mμ in diameter, and consist of an envelope covered with surface projections and an internal ribonucleoprotein component which is a single-stranded helix, 150-180 A in diameter, A high yield of infective SV5 is produced by primary cultures of rhesus monkey kidney (MK) cells, and the virus-cell interaction is moderate: infected cells divide normally, exhibit little cyctopathic effect, and cellular macromolecular synthesis is not inhibited. An electron microscopic study of SV5 replication in MK cells was undertaken. …

The Isolation And Characterization Of Soluble Brain Proteins, Gudrun Staub Bennett

Student Theses and Dissertations

The experiments described in this thesis were undertaken in order to define and purify proteins that might have a specific function in nerve activity. The studies were limited to rat brain proteins soluble in dilute aqueous buffers at neutral pH. Fractionation procedures for these proteins and two means of identifying individual proteins of interest in the fractions were developed. The soluble proteins were divided into two classes according to their solubility in mildly acidic conditions: the pH 5 soluble and pH 5 insoluble fractions. Two different large anatomical areas of the brain referred to as "cortex" and "brainstem," contained the …

West Midlands Development : Poison Plants In The West Midlands, T E H Aplin

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

TOXIC plants have caused considerable economic loss to stock raisers since the early days of settlement in Western Australia.

Although much is now known of the toxic materials contained in such plants, and although most of the plants have been thoroughly publicised, losses are still occurring in many areas.

Cockroaches And Their Control, Clee Francis Howard Jenkins

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

In this country some of the native varieties have become semi-domesticated and, in addition, two or three introduced forms are quite common.

New Strains Of Subterranean Clover : Prospects And Problems For The Seed Producer, B J. Quinlivan

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

THREE new strains of Subterranean clover—Daliak, Seaton Park and Uniwager—have been released.

In Western Australia, in other States and perhaps some overseas countries, the next few years will see many farmers or graziers summing up the merits and demerits of these strains and subsequently making a decision to change or not to change their present strains.

The History And Characteristics Of Troodos And Olympus Rose Clover, E T. Bailey, N. B. Gayfer

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

ROSE CLOVER is being produced and used in increasing quantities in south-western Australia. The first line named was designated Kondinin and five lines have now been given cultivar (variety) names.

One of the first samples of rose clover, C.P.I. 13949, introduced into Western Australia proved to be a mixture of two very similar types, differing visibly only in leaf markings.

The mixed sample was named Troodos,* and the selection from it, Olympus.

This paper describes the origin of the two varieties, their history and characteristics.

Wheat Weevil And The Farmer, Clee Francis Howard Jenkins, G. D. Rimes

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

INSECT pests have been taking toll of mans' crops and herds since very early times and despite modern control techniques the annual loss is still very high.

It has been estimated that damage to stored grain alone may average 10 per cent, per year, or, in terms of the West Australian harvest, a loss by weevils of about twice the capacity of the large Midland Junction bin.

The Dalmation Green Graft, D Mann, H. R. Rodda

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

THE GREEN GRAFT, introduced to the Swan Valley by Dalmatian vignerons many years ago, is carried out in late November or early December, at the stage when the pith of the growing shoot is beginning to whiten.

Because stock and scion are green at this time and the shoots have not started to ripen, the green graft calluses quickly.

The following fifteen free­ living copepods were identified: Eucalanus pileatus, Paracalanus par­vus, Centropages hamatus, Centropages furcatus, Temora stylifera, Temora longicornis, Labidocera aestiva, Labidocera species, Acartia tonsa, Oithona brevicornis, Oithona species, Oncaea venusta, Cory­caeus species, Sappharina nigromaculata and Euterpina acutifrons.

It was found that there is a definite seasonal distribution of cope­pods in Mississippi Sound with peak populations of copepods occu­rring in the spring, summer and fall.

Ecological Study Of The Effects Of Strip Mining On The Microbiology Of Streams, Ralph H. Weaver, Harry D. Nash

KWRRI Research Reports

The microflora of Cane Branch of Beaver Creek in McCreary County, Kentucky, which drains an area that was strip-mined between 1955 and 1959, was studied and compared with that of Helton Branch which drains a comparable area where there has been no mining. Differences include: the establishment of Ferrcbacillus ferrooxidans, for which procedures were developed for direct colony isolation from the stream; fewer saprophytic bacteria; more numerous and more diversified filamentous and unicellular fungi; and characteristic differences in algal flora. Representatives of 42 genera of filamentous fungi were identified. Of these, 21 were isolated only from Cane Branch. Representatives of …

Weight Gain And Carcass Measurements Of Pigs From Gilts Fed Adequate Vs. Protein-Free Diets During Gestation, W. G. Pond, J. A. Dunn, G. H. Wellington, J. R. Stouffer, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Fifty-two weanling pigs from six litters(Pond et al., 1968) were fed a standard 18% protein corn-soybean meal diet from weaning to slaughter. The six litters were from gilts paired on the basis of parturition date so that one gilt fed the control diet and one fed the “protein-free” diet (0.5% protein) from week 4 of pregnancy to parturition made tip each pair. Each dam was fed the control diet throughout lactation and nursed one-half of her own litter and one-half of a pairmate’s litter resulting from reciprocal transfer of one-half of each litter at birth. Individual bodyweight gains and feed …

Prairie Plants And Their Environment, J. E. Weaver

Papers of John E. Weaver (1884–1956)

When, in 1916, the writer came to the University of Nebraska as a young instructor, he came with a background that well fitted him for studies in the field. His research in the grassland and adjoining forests of southeastern Washington and adjacent Idaho had been completed and a fine acquaintance had been made with methods of examining the prairie both above and below ground level (Weaver, 1915, 1917). Similar studies in the area between the Missouri River and the Rocky Mountains were now to be made, and these have resulted in many new investigations that are of both scientific and …

A Study Of Some Physico-Chemical Changes In A Spread-Type Dairy Product During Storage, Alfredo E. Gudeikis

Electronic Theses and Dissertations

In the Dairy Science Department at South Dakota State University a new dairy spread product has been developed which has only 50% of the fat content of butter or margarine and 60% of the calorie value of the higher fat products. It is increased in solids content with nonfat milk solids. The purpose· of developing this product was to obtain a new outlet for milk constituents; desirably it was to be one that could regain the market sales which were lost by butter and are now enjoyed by the margarines. The high price of butter compared with the substitute product …

The Feeding Value Of High Dry Matter Corn Silage, Myers J. Owens

Electronic Theses and Dissertations

The important of corn in dairy cattle feeding is generally acknowledged. A popular way of preserving the crop is to make corn silage, thus using the whole plant for feed and preserving maximum feed per acre. The increased utilization of corn silage by dairymen may be due to its high energy yields per acre, high acceptability by cattle, and ease with it is incorporated into automated systems of harvesting and feeding. The increasing importance of corn silage in the United State is evidenced by the increasing acreages harvested as corn silage. In 1950 there were 4,937,000 acres planted with a …
