Some aspects of chronic respiratory diseases in coalminers in New South Wales, Australia.

Using 15N Dilution Method to Correct for Microbial Contamination When Assessing in situ Protein Degradability of Fresh Ryegrass

This experiment was done to investigate microbial contamination and in situ disappearance rates of dry matter (DM), N and 15N of fresh labeled ryegrass. Perennial ryegrass (Lolium perenne) were labeled with 15N during growth in a glasshouse, harvested at 4th leaves stage and were incubated up to 34 h in situ in the rumen of 3 individually housed sheep. The animals were fed 800 g/d chopped alfal...

Silicosis and lung cancer: a mortality study of compensated men with silicosis in New South Wales, Australia.

BACKGROUND Lung cancer mortality has been found to be in excess in several groups with silicosis, but allowance for smoking was not always possible. We investigated the lung cancer mortality in men with silicosis in New South Wales, Australia, who were compensated, making allowance for smoking habits. METHODS A mortality study of 1467 men with silicosis in New South Wales who were compensated...

A Partnership Model for Improving Service Delivery in Remote Papua New Guinea: A Mixed Methods Evaluation

Background The Community Mine Continuation Agreement Middle (CMCA) and South Fly Health Program (the Health Program) is a partnership for improving health service delivery in remote Papua New Guinea (PNG). The Health Program is delivered by a private contractor working in partnership with existing health service providers to improve service delivery using existing government systems, where poss...

Preliminary Evaluation for Vacuum Membrane Distillation (VMD) Energy Requirement

The energy requirement of vacuum membrane distillation (VMD) with or without recirculation was modelled using both experimental results and theoretical data. The trends are generally consistent between the theoretical and experimental data. Thermal energy contributes the most to the total energy required for the VMD process. To lower the thermal energy cost, waste heat resource and heat recover...
