in density due to particle content, the new elements which are continuously brought to the top of the cold wall are drawn from the top portion of the liquid and are of nearly uniform density. When A reaches its equilibrium depth, its downward flow is decelerated and it turns into the interior of the liquid, this motion being followed by the elements behind A. The equilibrium depth for A thus ac...

The potential bioaccumulation of Cs in marine food webs off Japan became a concern following the release of radioactive contaminants from the damaged Fukushima nuclear power plant into the coastal ocean. Previous studies suggest that Cs activities increase with trophic level in pelagic food webs, however, the bioaccumulation of Cs from seawater to primary producers, to zooplankton has not been ...

Background & objectives: Work-related illnesses account for a large number of social problems. According to occupational therapists, occupational diseases are considered as life-threatening factors for workers. The aim of this study was to measure air pollution to suspended particles and to assess the health risk of PM2.5 and PM10 exposure in the textile industry. Methods: This analytical-cros...

Differential pressure transducers can be used to monitor the suspended-sediment concentration in a water column. Suspended sediments with densities greater than water increase the fluid density, which is determined by measuring the fluid pressure change between two depths. Lewis and Rasmussen (1999) used a densimetric technique under controlled conditions to determine suspended-sediment concent...

The next decade will bring massive new data sets from experiments of the direct detection of weakly interacting massive particle dark matter. Mapping the data sets to the particle-physics properties of dark matter is complicated not only by the considerable uncertainties in the dark-matter model, but by its poorly constrained local distribution function (the ‘‘astrophysics’’ of dark matter). I ...
