The Australian population is ageing, and an increasing number of older Australians are becoming “grey nomads”, driving long distances on high speed rural roads. While many drivers in this age range are engaging in self regulation and limiting their driving to known roads, this population are driving on highly unfamiliar roads, and possibly engaging in unfamiliar practices such as towing large l...

in this research work, the parameters affecting the settling velocity within the thickeners were studied by introducing an equivalent shape factor. several thickener feed samples of different densities including copper, lead and zinc, and coal were prepared. the settling tests were performed on the samples, and the corresponding settling curves were plotted. using the linear regression analysis...

Abstract Working conditions of knowledge workers have been subject to rapid change recently. Digital nomadism is no longer a phenomenon that relates only entrepreneurs, freelancers, and gig workers. Corporate employees, too, begun uncouple their work from stationary (home) offices 9-to-5 schedules. However, pursuing permanent job in corporate environment still fundamentally different values tha...

Density interfaces in the water column are ubiquitously found in oceans and lakes. Interaction of settling particles with pycnoclines plays a pivotal function in nutrient transport between ocean layers and settling rates of marine particles. We perform direct numerical simulations of an elongated particle settling through a density interface and scrutinize the role of stratification on the sett...

We analyse high-resolution archival UVES data of turnoff and subgiant stars in the nearby globular cluster NGC6397 ([Fe/H]≈−2). Balmer-profile analyses are performed to derive reddening-free effective temperatures. Due to the limited S/N and uncertainties related to blaze removal, we find the data quality insufficient to exclude the existence of gravitational settling. If the newly derived effe...
