X-Ray Diode Using A Silicon Field Emission Photocathode, W. I. Karian, Larry V. Knight, David D. Allred, A. Reyes-Mena

Faculty Publications

We have produced arrays of 10,000 sharp p-type silicon points using an etch plus oxidation method. The points were used as electron emitters. No high vacuum cesiation or high temperature cleaning was needed to observe the electron emission. These are seen to be photosensitive sources of electrons at 200 K and 300 K. They were also used to produce AlKα x-rays. This constitutes the first use of etched, point arrays for generating electrons for x-ray sources.

Secondary Dust Generation In Rotary Coal Cutting., Danqing Xu

Graduate Theses, Dissertations, and Problem Reports (ETD)

In a rotary coal cutting system, the mined coal has to be transported through the cutting path. This transportation of mined coal through the cutting zone of a rotary cutting head is comparable to a rotary grinder. In the "grinder", the mined coal particles are subjected to secondary comminution, known as regrinding. A significant amount of coal dust could be generated during regrinding. This study was undertaken to investigate the mechanisms of regrinding and dust generation, to quantify the amount of dust generated during regrinding and evaluate the effects of influencing parameters on dust generation. Three comminution mechanisms of particles …

Biotransformation As A Mechanism Of Dichloroacetic Acid Potentiation Of Chloroform Hepatotoxicity., Hui-Min Yang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Dichloroacetic acid (DCA) and chloroform (CHCl{dollar}\\sb3{dollar}) both are major by-products formed during chlorination of drinking water. The potential threat to public health, of these compounds, is of great concern. Male and female rats were gavaged with DCA (2.45 mmol/kg), and then received an i.p. injection of CHCl{dollar}\\sb3{dollar} (0.25 ml/kg). The activities of plasma liver enzymes and the contents of plasma bilirubin were markedly increased in DCA-pretreated rats compared to their saline-pretreated controls. The possible mechanisms of CHCl{dollar}\\sb3{dollar}-induced hepatotoxicity potentiated by DCA treatment were investigated. It was hypothesized that the bioactivation of CHCl{dollar}\\sb3{dollar} in rats was enhanced by DCA treatment. The …

The A.D.E. Taxonomy Of Spreadsheet Application Development, Maria Jean Hall

Theses: Doctorates and Masters

Spreadsheets are a major application in end-user computing, one of the fastest growing areas of computing. Studies have shown that 30% of spreadsheet applications contain errors. As major decisions are often made with the assistance of spreadsheets, the control of spreadsheet applications is a matter of concern to enduser developers, managers, EDP auditors and computer professionals.

The application of appropriate controls to the spreadsheet development process requires prior categorisation of the spreadsheet application. The special-purpose A.D.E. (Application, Development, Environment) taxonomy of spreadsheet application development was evolved by mathematical taxonomic methods to categorise spreadsheet development projects to facilitate their management and …

The Effect Of Canteen Menu On Nutritional Knowledge, Attitudes And Behaviour Of Year Five Students, Sharon Mcbride

Theses: Doctorates and Masters

Eating habits are learned during childhood, and patterns of behaviour established in childhood have important health ramifications throughout life. Over half of all deaths in Australia are linked to diet with over-consumption of saturated fat, sugar and salt, and lack of fibre being identified as particular problem areas. Nutrition education is an important component of primary health education curricula, and yet school canteens, and integral part of the school environment, do not necessarily offer healthy food choices that support nutrition instruction in the classroom. This study investigated the effect of canteen menu on student knowledge and attitudes toward nutrition and …

An Evaluation Of The Procedures Used To Assess And Remediate The Perceived Writing Difficulties Of Undergraduate Students In The Faculty Of Education At Edith Cowan University, Les Puhl

Theses: Doctorates and Masters

The standards of written literacy of teacher-education students at Edith Cowan University are perceived by many staff to be inadequate. The Faculty of Education's response to this perceived inadequacy is to carry out a mandatory skills-based remedial writing programme for students whose literacy competencies are judged to be deficient, The instrument used to assess the students' literacy competencies is the English Skills Assessment test. The students' performances in the various skills which the test purports to measure, also determine the area in which they are given remedial instruction if the results of the test suggest this is necessary. However, many …

Reasons For The Underrepresentation Of Females At Head Of Department Level In Physical Education In Government Secondary Schools In Western Australia: Perceptions Of Female Physical Education Teachers, Regina D. Bloot

Theses: Doctorates and Masters

This study focuses on reasons why so few females hold Head of Department positions in physical education in government secondary schools in Western Australia. Despite the almost equitable proportion of females and males teaching the subject, and the absence of Ministry of Education policy constraints on female promotion since 1972, females remain grossly underrepresented in leadership roles. In 1991, women held only five (7%) of the 70 substantive Head of Department appointments. Individual indepth interviews were used as the means of data collection to document female teachers' own accounts of their lives, career aspirations, and what they perceived to be …

A Case Study Of Two Year Six Classes Involved In A Health-Related Fitness Intervention, Andrew T. Medland

Theses: Doctorates and Masters

Children are not as active as they may appear and they do not voluntarily engage in moderate to high intensity activity as commonly perceived by the general public. With coronary heart disease risk factors now found to have origins in childhood there is a real need for children to adopt lifestyles that will produce healthier adults. In Perth the Western Australian Schools Physical Activity and Nutrition project (WASPAN) has been implemented, as a Year 6 intervention, addressing the problems of poor nutritional habits and low activity levels. The focus of this case-study was to describe the physical activity component of …
