Pulsations generated by personal sampling pumps modulate the airflow through the sampling trains, thereby varying sampling efficiencies, and possibly invalidating collection or monitoring. The purpose of this study was to characterize pulsations generated by personal sampling pumps relative to a nominal flow rate at the inlet of different respirable cyclones. Experiments were conducted using a ...

This paper tends to investigate the performance of a separator cyclone used in cement industries in Iran. This investigation was performed using CFD modeling, which is validated by other valid studies. Separator cyclone performance includes of two important parameters as pressure drop and collection ratio. In this presented study, the pressure drop has been considered to assess the performance ...

Networks of no-take marine reserves (NTMRs) are widely advocated for preserving exploited fish stocks and for conserving biodiversity. We used underwater visual surveys of coral reef fish and benthic communities to quantify the short- to medium-term (5 to 30 years) ecological effects of the establishment of NTMRs within the Great Barrier Reef Marine Park (GBRMP). The density, mean length, and b...

Tropical cyclones may be destructive in the coastal region, such as Gonu tropical cyclone, which affected Arabian Peninsula and parts of southern Iran 2007. In this study, a coupled MIKE 21/3 HD/SW (hydrodynamic/spectral wave) model was used to simulate inland flooding inside Sur port during cyclone. The 21 Cyclone Wind Generation (CWG) tool utilized generate cyclone’s wind pressure field. requ...

The purpose of the controller presented is to maintain the proportion of carbon content in the products of the coal washing dense medium cyclone (DMC) at a certain level by optimally manipulating the density of the heavy medium. In practice, the DMC processes are mainly controlled by empirical methods which are process specific and cannot satisfy the industrial requirements today. As a result, ...

Abstract Tri-flo cyclone, as a dense-medium separation device, is one of the most typical environmentally friendly industrial techniques in coal washery plants. Surprisingly, no detailed investigation has been conducted to explore effectiveness tri-flo cyclone operating parameters on their representative metallurgical responses (yield and recovery). To fill this gap, work for first time process...

Purpose of Review Melioidosis epidemiology is susceptible to climate change through direct and indirect effects on human encounter with the causative agent, Burkholderia pseudomallei. This review describes the current depth of knowledge and recent advances in the understanding of this relationship and applies it to observations of melioidosis in Western Australia. Recent Findings High maximum...
