Quantitative Analysis Of Thin Films By Dc Arc Optical Emission Spectroscopy, Arnold W. Hogrefe Jan 1977

Quantitative Analysis Of Thin Films By Dc Arc Optical Emission Spectroscopy, Arnold W. Hogrefe

Retrospective Theses and Dissertations

The use of DC arc optical emission spectroscopy (OES) for quantitative analysis of thin films deposited on graphite electrodes was investigated as a process control tool. Three binary systems were evaluated: nickel-chromium, phosphorous-silicon, and silicon-aluminum. Sampling by direct deposition onto graphite electrodes placed in the deposition chamber with product runs proved to be a rapid, representative, and non-disruptive technique. Standard electrodes were prepared for each system either by evaporation of solutions of known concentration onto the tips of electrodes or by weighing out powdered standards of the appropriate concentrations. Standard curves were then prepared by burning multiple sets of standard …

Task 1 Evaluation On The Thickness Of The Mobile Surface Layer, Dam Neck, Virginia : Final Report To Malcolm Pirnie Engineers, Inc., John D. Boon Jan 1977

Task 1 Evaluation On The Thickness Of The Mobile Surface Layer, Dam Neck, Virginia : Final Report To Malcolm Pirnie Engineers, Inc., John D. Boon

Reports

Our objective under Task 1 was to make an assessment of the sedimentary features (sediment texture and structures) present in cores (obtained by vibratory method) at the project site in order to express an opinion as to the thickness of the "surface mobile sand layer". The mobile sand layer is that surficial sediment layer undergoing cut and fill episodes due to present day wave and current induced sediment transport. In addition, this report contains information extracted from existing literature on recent (1859 to 1968) shoreline behavior in the vicinity of the proposed outfall and on some aspects of surface sediment …

Wood Duck Nesting Boxes, Dick Gersib Jan 1977

Wood Duck Nesting Boxes, Dick Gersib

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The Wood Duck (Aix sponsa), Nebraska's only tree nesting duck, has four major requirements for breeding habitat. These requirements a r e food, cover, water, and suitable nest cavities which govern the distribution of breeding wood ducks in Nebraska. Without any one of these four requirements, wood ducks would not be able to maintain a breeding population.

Very little is known about the spring food requirements of nesting wood ducks, and only the most general comments can be made. It is known t h a t protein requirements for both the hen and ducklings are high. Pairs, especially …


Heisenberg Theory Of Ferromagnetism: Constant Coupling Revisited, Harry A. Brown Jan 1977

Heisenberg Theory Of Ferromagnetism: Constant Coupling Revisited, Harry A. Brown

Physics Faculty Research & Creative Works

The Heinsenberg theory of ferromagnetism has been treated by many types of approximations; one of the more successful is known as constant coupling. The literature constants several different ways of arriving at results like those of the constant-coupling approximation, but proofs that they are indeed equivalent are lacking in some cases. It is shown that two of these methods are equivalent for spin 1/2 and explicitly demonstrated that both yield exactly the constant-coupling results, though simpler in use and concept than the latter. Finally, it is shown that one of the two methods yields the same Curie temperatures as constant …

Some Basics Of Marron Production, Department Of Agriculture, Western Australia Jan 1977

Some Basics Of Marron Production, Department Of Agriculture, Western Australia

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

marron are native to the South-West of Western Australia, and are keenly sought by inland fisher-men. However, supplies do not equal the apparent demand.

One solution is to cultivate marron in farm dams, or more intensively as a commercial enterprise.

This article suggests a few guidelines for marron production.


Effect Of Soil Properties On Copper Availability To Plants, R. F. Brennan Jan 1977

Effect Of Soil Properties On Copper Availability To Plants, R. F. Brennan

Experimental Summaries - Plant Research

Experimental glasshouse work involved examining the decrease in effectiveness of copper fertilizer in the soil through time. This seems to conflict with Mr. J.W. Gartrell's programme of field trials which have shown no evidence for any decline in the effectiveness of the original application. 1. Ammonium cxalate extractable Cu. TABLE 3 - 77GL3.

Lupin Trials, J Moore Jan 1977

Lupin Trials, J Moore

Experimental Summaries - Plant Research

Trials in lupins this year concentrated on testing herbicide for post emergence use in lupins. Of the 20 herbicides tested 12 did not cause significant decreases in crop density and/or yield. However, weed control was often poor and the herbicide phytotoxicity tended to vary between sites. (Chapman, Badgingarra and Avondale). The Chapman and Avondale trials were not harvested because of drought. Trials in 1978 should determine if any of the herbicides tested can safely be recommended. Lupins - summary.

Effect Of Deforestation By The Douglas-Fir Tussock Moth On The Quality Of Streamflow And Stream Productivity Parameters, Martin Ed Hicks Jan 1977

Effect Of Deforestation By The Douglas-Fir Tussock Moth On The Quality Of Streamflow And Stream Productivity Parameters, Martin Ed Hicks

All Master's Theses

The purpose of this study was to determine if deforestation by a recent outbreak of Douglas-fir tussock moth and logging of such deforested timber has had any effect on stream water quality. To determine this, seven different watersheds of three types were examined. The three types were: undamaged watersheds as controls, watersheds with deforestation and watersheds with deforestation where the timber was subsequently logged. Twenty-four variables were used to determine water quality. Included were seven biological and seventeen chemical variables.

In general, the results indicate only seasonal fluctuations and differences between watersheds due to inherent properties of individual watersheds. Increased …
