A New Opportunity to Pulp Bagasse in Australia?

Despite the large quantity of sugarcane grown in Australia, no bagasse is pulped in the country. This is largely because of an established pulp industry based on the abundant native hardwood resources. However, increasing demand for fibre and the limited availability of additional forest areas make bagasse pulping attractive. Issues relating to infrastructure and economics are discussed, and scenarios of acceptable risk identified. It is shown that there should be scope for the production of bleached bagasse pulp in Australia.

Female Entrepreneurship in Australia: Revisited

This paper is a ten-year follow-up on a study conducted in 1995 that profiled women entrepreneurs in Australia (Bennett and Dann 2000). The aim of the paper is to identify changes in demographic profile, motivation and personality traits of women entrepreneurs over the past ten years by replicating a study from1995 and reporting the results.

Indoor exposure to submicrometer particles and PM2.5 in residential houses in Brisbane, Australia

As part of a large study investigating indoor air in residential houses in Brisbane, Australia, the purpose of this work was to quantify indoor exposure to submicrometer particles and PM2.5 for the inhabitants of 14 houses. Particle concentrations were measured simultaneously for more than 48 hours in the kitchens of all the houses by using a condensation particle counter (CPC) and a photometer (DustTrak). The occupants of the houses were asked to fill in a diary, noting the time and duration of any activity occurring throughout the house during measurement, as well as their presence or absence from home. From the time series concentration data and the information about indoor activities, exposure to the inhabitants of the houses was calculated for the entire time they spent at home as well as during indoor activities resulting in particle generation. The results show that the highest median concentration level occurred during cooking periods for both particle number concentration (47.5´103 particles cm-3) and PM2.5 concentration (13.4 mg m-3). The highest residential exposure period was the sleeping period for both particle number exposure (31%) and PM2.5 exposure (45.6%). The percentage of the average residential particle exposure level in total 24h particle exposure level was approximating 70% for both particle number and PM2.5 exposure.
