Description:
Most of Australia's zinc production is by the electrolytic zinc process, in which zinc is electrowon from an acid sulphate solution. The process is known to be exceptionally sensitive to the presence of trace impurities. At the Electrolytic Zinc plant (Risdon, Tasmania), isobenzofuranone (pthalide) has been detected in the electrowinning circuit, and found in higher concentrations during efficiency slumps. It was found that di-2-ethylhexyphthalate, (present in the liners and plastics used in the electrowinning circuit), is reduced to isobenzofuranone under the electrolysis conditions employed. In addition, an investigation involved a constant current electrolysis of a synthetic zinc electrolyte, as identified an additional pathway for the productionof isobenzofuranone. 2-Naphthol, added to the electrolysis circuit for current efficiency purposes, is also a major precursor of isobenzofuranone. 2-Napthol and possibly 1-nitroso-2-napthol can be oxidized to pthalic acid, either at a lead anode or via anode oxidation productions, and the phthalic acid produced can be reduced to isobenzofuranone at a zinc cathode. In addition, it was found that isobenzofurane is further reduced at the potential of zinc deposition to ultimately yield 2-methylbenzaldehyde. This compound, which has also been detected in Risdon plant electrolytes, is also toxic in the zince electrowinning circuit. The compound 2-methylabenzyl alcohol has also been detected via GLC examination of Risdon plant liquors. However, this compound was not detected in the present investigation, and thus no explanation can be offered for its presence in plant electrolytes. The toxicity of zinc electrolyte impurities on current efficiency was determined by a cyclic voltammetric technique. The results of this investigation indicate that the presence of isobenzofuranone and 2-methylbenzaldehyde can significantly lower current effciency, and the compounds phthalic acid and 2-methylbenzyl alcohol also lower efficiency.

Much has been written about seated working posture - particularly in the late 19th and early 20th centuries, and the furniture associated with achieving what is commonly referred to as the "German Square" postural geometry (after Mandal, 1974). The physical sciences aspects of chair, desk and associated furniture ancillary to the task required of the seated worker, have been described in the scientific literature and the standards and guideline publications of the authorities of many countries of the western world. The most important contribution of multi-adjustable furniture to the reduction of postural discomfort and musculo-skeletal complaints is recognised. As a result a variety of standards and guidelines concerning some of these aspects exists in countries such as the United Kingdom, Canada, United States of America, Germany, Australia and the Scandinavian countries. The International Organisation for Standardisation published document TC136/SC7 in 1978, consolidating such existing standards. Less emphasis has been placed on the interface of the information exchange and the comfort, performance and preferences of the seated worker; ie., the practically, the comfort and the intrinsic safety of the working posture prescribed by the model established by the many standards. Existing specifications and guidelines differ in their orientation towards operator performance and comfort of the operator, in as much as some purport to be "furniture standards", for example C.E.N, Comite European de Normalisation, Paris, 1980, while others purport to be "postural standards", for example, International Organisation for Standardisation document TC 136/SC7 (1978). The standards are uniform in matters of upright trunk and 90° upper and lower limb geometry, but are divided in the lineal dimensions applied to eye height above the floor, shoulder acromion to home row of keys (or pen-grip position of the dominant hand and fingers), and eye distance to copy.

Length of stay in hospital post-amputation for elderly amputees gait trained using the whole method of re-education at the Queen Elizabeth Geriatric Centre is shorted than is usual in other parts of Australia. There was a need to investigate the gait quality and functional ability of these amputees to asses the adequacy of their post-rebhabilation gait, and to establish a benchmark against which to measure alternative treatment outcomes.

The assessment of barley and malt quality for a barley breeding program was revised. The small size of the samples available in breeding requires the development of special methods that may differ slightly from those used by the malting and brewing industry when dealing with much larger samples of grain. Small-scale methods for malt extract determination were investigated. A new method using 1 g of malt in a 10 M1 mash was proposed for use in barley breeding. Near infared methods for barley and malt analysis were studied. Methods for distinguishing barley and malt varieties. A system for capture and storage of data and analysis of results by computer was developed specifically for a barley quality laboratory supporting a barley breeding program.

Description:
The timing of breeding and habitat preference in the stubble quail (Coturnix pectoralis) were assessed at two study sites, Dookie and Mitiamo, in the north of Victoria. Surveying was over and eight month period between September 1993 - April 1994. Reproductive timing was determined by monitoring changes in the gomad size of shot birds. Breeding events were verified by disproportionate increases in the number of young birds shot. Population density was measured as an indicator of habitat preference. Site characteristics known to affect habitat selection were monitored. Breeding was in spring and autumn. Spring breeding coincided with the period of maximum plant growth. Autumn breeding was stimulated by above average late summer rainfall. Male stubble quail were shot in greater numbers during a known breeding event. Stubble quail preferred areas of lightly grazed pasture dominanted by native grass species. Recently harvested wheat and barley stubble provided an abundant short-term food supply, however the ability of this habitat type to support resident stubble quail populations is questioned. Stubble quail population density appeared to be strongly influenced by territorial behaviour during breeding. Implications for the management of this game species are discussed and future lines of research recommended.

The purpose of the study was to examine the effect of a group training program, based on cognitive behavioural theory and techniques, on the problem-solving skills of adolescents. Evidence of a link between suicidal ideation (engaging in suicidal thinking) and reported deficits in social problem-solving or coping competence levels in adolescents is an area of investigation that offers some hope for suicide primary prevention programs. The study tried to determine if teaching social problem solving skills in a school would better equip adolescents with coping with problematic situations. The work of Hawton (1997) Hawton and Kirk (1989), Lerner and Clum (1990) and McLeavey, Daly, Ludgate and Murray (1994) formed the basis of the training program design. The emphasis was on general problem-solving skills rather on a participant’s specific current problems. Included was training in listening skills, assistance in developing problem-solving skills rather on a participant’s specific current problems. Included was training in listening skills, assistance in developing appropriate problem-solving behaviours and role simulation through the use of structured video case scenarios. Seventy four male and female year 10 secondary school students were subjects in the study. They were randomly divided into two, approximately equal, groups. Thirty six subjects established the control group and the remaining thirty eight constituted the experimental group. The findings indicated that students exposed to the problem solving training program did not have significantly higher problem-solving ability, as measured by the Problem Solving Inventory (PSI) than those who were not exposed to the training. However, females in the experimental group were significantly more likely to make conscious decisions about when they would approach or avoid a problem when compared to control group females. It is suggested that the adaptation of training, designed for suicidal clients, needs to be explored further for application to Year 10 students in the general population. More research is needed into ways to provide school based preventative training programs that will assist in the development of coping skills.

"There is a dearth of information about the current use and management of hazardous substances in workplaces. This project aimed to contribute knowledge in this area by drawing on the practical experience of worker-elected health and safety representatives. This was undertaken by surveying a random sample of 7178 representatives registered with former South Australian Occupational and Safety Commission's Health and Safety Representatives Database. The survey results indicated widespread use of hazard substances although there were differences between industries and work force sectors in the range of chemical types used, the nature and degree of contact that workers have with them. Use of some chemical types was also widespread in a number of industries. Container labelling and access to material safety data sheets were found to be established in many workplaces and some form of assessment to decide how to protect workers was also often undertaken. Baseline information was obtained against which the impact of proposed regulatory reforms to control workplace hazardous substances (consistent with Workplace Australia's National Model Regulations for the Contol of Workplace Hazardous Substances) can be evaluated. This information can also be used in the planning and targeting of educative and other preventive strategies to minimise risks to health and safety arising from work with hazardous substances."

Description:
The principal aim of this study is to survey parents' perceptions of the influence of imported children's television programs on their children's behaviour. The survey was carried out in the Jakarta area. The study was promoted by a desire to investigate the claim made by some social commentators in Indonesia recently that children's behaviour was worsening, especially since the rapid expansion of commercial television. For the survey, a group of 388 parents of mixed socio-economic status were questioned. As a further step, qualitative research techniques were used to interview key personnel from the Indonesian television industry. Both the quantitative and qualitative data obtained was related to imported children's programs broadcast on both commercial and government channels. The result indicate that there w as no significant correlation between increased negative behaviour in children and the watching of imported children's programs. Most parents were inclined toward the view that they could not be certain whether or not their children's behaviour was influenced by imported children's television programs. Neither did they consider such programs to have a negative influence on their children's behaviour. Variation in parents' socio-economic status did not lead to a significant difference in percentages. Since parents did not perceive there to be any correlation, there may be other factors at work leading children to behave in increasingly negative ways, or perhaps the social commentators are mistaken and children's behaviour is not worsening at all
