A Study Of Alveolar Bone Loss And Two-Hour Postprandial Blood Sugar Levels, R. Leslie Arnett
Loma Linda University Electronic Theses, Dissertations & Projects
Two-hour postprandial blood sugar determinations were carried out on 500 patients referred for periodontal care. The mean percentage of alveolar bone loss around the mandibular bicuspid teeth was established for each individual. The subjects were then grouped according to blood sugar levels and the mean alveolar bone loss was calculated. The group was separated into male and female sub-groups and data was computed for these segments as well as the total sample. The data was evaluated in a similar manner for those subjects between 40 and 49 years of age.
No Chi-square determinations were statistically significant but significance in differences …

Isolation And Partial Characterization Of The Toxic Substance From Eremocarpus Setigerus Benth, Shuliang Lee
Loma Linda University Electronic Theses, Dissertations & Projects
The work on the active substance of Eremocarpus setigerus Benth has been previously performed by Naito and Noller. However, the investigation was not complete. Therefore we isolated and tested this substance by steam distillation and thin layer chromatography technique. A yellow sticky toxic substance was isolated with Rf values of 0.15 in benzene system and 0.57 in benzene-absolute ethanol (95:5 v/v) system.
The toxic substance which is free of halogen, nitrogen, and sulfur, is soluble in ethyl ether, ethanol, and concentrated sulfuric acid. It has a maximum absorption in the ultraviolet region that indicates the presence of unsaturation. Its infrared …

Biological Aspects Of Heat Pollution, Theodore Olson
Biological Aspects Of Heat Pollution, Theodore Olson
Journal of the Minnesota Academy of Science
The importance of temperature as an environmental factor has long been recognized by the ecologist, and its special impact upon the aquatic ecosystem has been of interest to aquatic biologists since they first began to observe interactions between living things and the physical environment. Interest in water temperatures as an environmental factor has recently become more widespread; and one aspect of the phenomenon, namely "thermal pollution," has attracted special attention.

FARMING the light lands of the West Midland area would be impossible without fertilisers.
Most light land areas are inherently very low in phosphate and also require nitrogen.
The nitrogen can come from fertiliser for cereal crops, or can be built up by growing appropriate legume pasture plants such as clovers and lupins.

West Midlands Development : Cereals For The West Midlands, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
THE sandplain soils and climate of the West Midlands area are primarily suited to grazing.
However, the place of cereals is receiving a great deal of attention in view of their advantages in the early stages of development, and the need for the diversification of farm production.

Wheat In Development Programmes For New Esperance Farmers, R J. Doyle, G. D. Oliver
Journal of the Department of Agriculture, Western Australia, Series 4
IN the December, 1967, issue of the Journal of Agriculture, we reported on five development budgets for the Esperance region.
The aim of the exercise was to find out if a new settler concentrating on sheep, with $20,000 available for development after acquisition of land, could make a reasonable living for himself and his family while developing his farm.

The Phosphorus Fertilisers : How They Compare, Walter Jacob Cox
Journal of the Department of Agriculture, Western Australia, Series 4
ALTHOUGH 'double' or 'concentrated' superphosphate was first commercially manufactured in 1872 it was not until the 1950's that it became a major commercial fertiliser. In 1965 it accounted for about 15 per cent, of the world production of phosphatic fertilisers.
The Function And Use Of Sulphur Dioxide In West Australian Winemaking, D Mann
The Function And Use Of Sulphur Dioxide In West Australian Winemaking, D Mann
Journal of the Department of Agriculture, Western Australia, Series 4
THE judicious use of sulphur dioxide is perhaps the most important of the fundamentals of winemaking in a hot climate.
Western Australia's vintage, centred in the Swan Valley just a few miles north-east of Perth, is subjected to some of the highest summer temperatures experienced by a quality wine producing district.
In this environment, it is important to make good use of sulphur dioxide to avoid wine spoilage.

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 …
