The Interrelation Of The Adrenal And Posterior Pituitary Glands In Water And Electrolyte Metabolism, Frederic A. Giere

Biology ETDs

The secretions of the adrenal medulla account for many of the instantaneous responses of the animal body to various stimuli, but it has not been established that such secretions play any significant role in the endocrine regulation of salt and water metabolism. On the other hand, it has been established that the adrenal cortex and the antidiuretic hormone of the posterior pituitary are intimately involved in such processes. Certain compounds of the amine type, among which are the adrenal medullary hormone, do have a dramatic action on water diuresis; but it is questioned whether these substances are involved in the …

Radiosensitivity Of Mice In Relation To Heightened Metabolic Activity During And Immediately Prior To Exposure To 220 Kv X-Rays, M. Rosalie Henneke

Bachelors’ Theses

The manner in which certain factors influence the susceptibility of protoplasmic systems to ionizing radiations is not as yet well understood. Of prime importance among these factors is metabolic rate; it has been demonstrated that there exists a definite re­lationship between metabolic level and the lethal effects of such radiations. At the outset it must be pointed out that there are two principal problems in this connection; that is to say, radiosensitivity can be studied in relation to metabolic rate prevailing during or subsequent to exposure. One of the most frequently used criterion of radiosusceptability is mortality rate.

Isotomine Collembola From The Sandia Mountains Of New Mexico, Harold Scott

Biology ETDs

This paper records the first study of Collembola ever made in the Sandia Mountains and one of the first ever made in New Mexico even though the state presents excellent opportunities for study of this order. The Sandia Mountains are an ecologist’s paradise and it is probable that two hundred or more species of Collembola occur in this region alone. The entire state of New Mexico, possessing the extremes of elevation and the large geographical extent necessary to produce a great diversity of habitat types, probably contains nearly twice this number.

Bulletin No. 361 - How Much Barley For Turkeys, C. I. Draper

UAES Bulletins

During recent years high energy turkey diets containing com as the sole source of ground grain have been fed extensively. Corn has been used as the grain part of the mash because of its high energy, low fiber qualities, and because its deficiencies in amino acids, vitamins, and minerals have been determined by research. Supplements to overcome these deficiencies have been added to high energy corn diets. Excellent results have been obtained when adequate supplementation of vitamins, amino acids, and minerals were made.

In this area frequent inquiries are made as to the possibilities of substituting barley for part or …

Control Household Insects, John A. Lofgren

SDSU Extension Circulars

The development and general acceptance of the new insecticides has greatly helped housewives in their battles with insects found in the home. Yet the use of these chemicals does not rule out the importance of sanitation and good housekeeping in preventing the establishment of these pests. Sanitation is a basic principle of pest control. Insects found in South Dakota homes destroy and contaminate foods and ruin fabrics. Some attack our dwellings and other buildings; others bite or annoy humans, carrying diseases and causing irritation or secondary infections. The presence of other insects merely constitutes a nuisance. Even the most well-kept …

The Pruning Of Fruit Trees—Part 2. Framework Pruning Of Deciduous Trees, H R. Powell

Journal of the Department of Agriculture, Western Australia, Series 3

The early prunings are very important for the reason that they determine the height of the trunk, and the number and spacing of the main and secondary arms and leaders. Mistakes made then are difficult to rectify later on.

Plant Disease - Black Spot (Anthracnose) Of Grapes, W P. Cass Smith, H L. Harvey, W R. Jamieson

Journal of the Department of Agriculture, Western Australia, Series 3

Black spot or Anthracnose of grapes caused by the fungus Elsinoe ampelina is a widespread and serious disease. In commercial vineyards it is often responsible for considerable reduction in yield and quality of fruit, and in home gardens also it may prove very damaging. Under commercial conditions the disease has proved difficult to control in seasons favourable for its development despite the routine application of accepted fungicides. Fortunately, preliminary results of recent spray trials indicate that greatly improved control is likely to result in future from the use of a number of new fungicides.

Diseases Of Bees, R S. Coleman

Journal of the Department of Agriculture, Western Australia, Series 3

All beekeepers dread the appearance of disease in their hives, for it means at the least a large drop in the honey crop and at the worst, complete destruction of whole apiaries and the beekeepers' means of livelihood. Quite apart from the economic loss, beekeepers are usually men who work with bees because they like them, and naturally they do not want to see whole colonies destroyed.

The Preperation Of Rose Beds, C C. Hillary

Journal of the Department of Agriculture, Western Australia, Series 3

Roses equal to the world's best can be produced almost anywhere in the south-western part of Western Australia with little more attention than is bestowed on most other flowers. It is essential, however, that suitable soil conditions should be provided for the plants.

Bracken Fern Control, F E. Ryan

Journal of the Department of Agriculture, Western Australia, Series 3

Bracken fern occurs over a large proportion of the civilised world and is recognised in all countries as a serious pasture pest. Its control is a matter of great concern. In Western Australia large areas have been invaded by bracken, and recommendations for its control have been made from time to time. Generally speaking, control measures are aimed at the removal of the frond cover and stimulating pasture growth beneath.

Swill-Feeding Of Pigs, J F. Robinson

Journal of the Department of Agriculture, Western Australia, Series 3

The feeding of food refuse (commonly known as "swill") to pigs is governed by regulations 1 under the Stock Diseases Act and any owner of pigs employing this method of feeding must be in possession of a license issued by the Chief Inspector of Stock. To obtain such a license, he must have installed an approved type of heat treatment plant.

Insect Pest - The Black Beetle, C F.H Jenkins

Journal of the Department of Agriculture, Western Australia, Series 3

The black beetle (Heteronychus sanctae-helenae Blanchard) is a native of South Africa which seems to have first gained a footing in Australia in about 1930, for it was then recorded as a pest of maize in New South Wales. (Gurney 1934). The first reports of the beetle in Western Australia came from Albany in 1938 when some damage to potatoes was experienced. Since that date the beetle has gradually spread and it is now common in the metropolitan area where it infests golf greens, tennis courts and similar turf areas. It is also gradually increasing in importance as a market …

Anther Development In A Male Sterile Line Of Corn, Richard J. Vogl

Bachelors’ Theses

Production of viable pollen through growth and differentiation of the anther appears to depend on the interaction of the tapetum and sporogenous tissue. Very little is known about the nature of this interaction. One way to approach this problem is to study the development of the anther in cases where no viable pollen grains are produced. Highly inbred lines of male sterile corn which are completely pollen sterile have been obtained and are available for study.
