Gas-solid flow systems are found in many industrial applications such as catalytic reactions, pneumatic conveying, granulation, crystallisation, mineral classification, etc.The operational hydrodynamics can vary depending on the operation method from fast dilute flow, which is dominated by collisional particle-particle contacts, to dense slow flow,
Increased sediment load during a large-scale dam removal changes nearshore subtidal communities.
The coastal marine ecosystem near the Elwha River was altered by a massive sediment influx-over 10 million tonnes-during the staged three-year removal of two hydropower dams.We used time series of bathymetry, substrate grain size, remotely sensed turbidity, scuba dive surveys, and towed video observations collected before and during dam removal to
A Struggle for Survival: Meaning of Late Life in a Rural District in Uganda: A Qualitative Study
Background: Between 2015 and 2050, the aging population of Uganda (aged 50 years and older) will be nearly doubled.Therefore, later-life problems have become an area of increasing research and policy interest.This study aimed at exploring how aging people living in extreme poverty in a low-income country experience their everyday life and what kind
Low-Cost, Distributed Environmental Monitors for Factory Worker Health
An integrated network of environmental monitors was developed to continuously measure several airborne hazards in a manufacturing facility.The monitors integrated low-cost sensors to measure particulate matter, carbon monoxide, ozone and nitrogen dioxide, noise, temperature and humidity.The monitors were developed and tested in situ for three month
Screening the Efficacy and Safety of Molluscicides from Three Leaf Extracts of Chimonanthus against the Invasive Apple Snail, Pomacea canaliculata
Pomacea canaliculata, the invasive snail, is a host of the parasitic nematode Angiostrongylus cantonensis, which has adverse effects on the agriculture system femigrow capsules and human health.This work evaluated the molluscicidal activity of petroleum ether extracts (PEEs) from three species of Chimonanthus against the snail P.canaliculate.Pcp (P
