(1998)Journal ArticleThe first results obtained using a SOI device for microdosimetry applications are presented. Microbeam and broadbeam spectroscopy methods are used for determining minority carrier lifetime and radiation damage constants. A spectroscopy model is presented which includes the majority of effects that impact spectral resolution. Charge collection statistics were found to substantially affect spectral resolution. Lateral diffusion effects significantly complicate charge collection

(1996)Conference PaperThe Mungi single address space operating system provides a protected procedure call mechanism named protection domain extension (PDX). The PDX call executes in a protection domain which is the union of (a subset of) the caller`s, and a fixed domain associated with the procedure. On return, the caller`s original protection domain is reestablished. Extensive caching of validation data allows amortisation of setup costs over a possibly large number of invocations. The PDX mechanism forms the basis for object support in Mungi, particularly encapsulation. It is also used for accessing devices, and to implement user-level page fault handlers.

(1998)Journal ArticleGrowth under elevated [CO2] promoted spring frost damage in field grown seedlings of snow gum (Eucalyptus pauciflora Sieb. ex Spreng.), one of the most frost tolerant of eucalypts. Freezing began in the leaf midvein, consistent with it being a major site of frost damage under field conditions. The average ice nucleation temperature was higher in leaves grown under elevated [CO2] (– 5.7 oC versus – 4.3 oC), consistent with the greater incidence of frost damage in these leaves (34% versus 68% of leaves damaged). These results have major implications for agriculture, forestry and vegetation dynamics, as an increase in frost susceptibility may reduce potential gains in productivity from CO2 fertilization and may affect predictions of vegetation change based on increasing temperature.

(1997)Journal ArticleObjective: Intravenous sedation of involuntary psychiatric patients is practised in almost all hospitals in New South Wales. Despite its widespread use, little has been published about the medications used or their safety and efficacy. The present study reports the frequency and reasons for intravenous sedation, the medications used, and the incidence of adverse effects. Method: Eighteen of 21 acute psychiatric admission units in the State were reviewed. The medical records of a random sample of 495 patients admitted involuntarily during 1990 were examined and information from the progress notes, drug charts and physical observations was recorded and subjected to statistical analysis. Results: Of the 495 patients, 132 (27%) were intravenously sedated. Eighty-six per cent (86%) of patients received a combination of haloperidol or diazepam, usually 20 mg of each drug. The threat of violence was the most significant patient characteristic predicting the use of intravenous sedation. Patients with mania or intoxication were relatively more likely to be intravenously sedated than other diagnostic categories. Patients admitted via accident and emergency departments and those admitted to teaching and metropolitan general hospitals compared to rural and large psychiatric hospitals were significantly more likely to receive intravenous sedation. The most common complications of intravenous sedation were dystonia (37%), hypotension (8%) and confusion (5%). The incidence of phlebitis and other extrapyramidal side-effects was probably under-reported. Conclusion: About one in four involuntary psychiatric patients receive intravenous sedation in NSW. Intravenous sedation is more likely when patients are admitted through accident and emergency departments to teaching or metropolitan hospitals, and pose a threat of violence. Intravenous sedation was shown to be a safe procedure given certain precautions.

(1998)ReportThe Melbourne Gay Community Periodic Survey is a cross-sectional survey of gay and homosexually active men recruited through a range of sites in the Melbourne metropolitan area. The project was funded by the Victorian Department of Human Services. The Periodic Survey provides a snapshot of sexual and HIV-related practices among gay and homosexually active men.
