Introduction: A hallmark of sepsis is early onset microvascular dysfunction. However, the mechanism responsible for maldistribution of capillary blood flow is not understood. Evidence suggests red blood cells (RBC) can sense local oxygen (O2) conditions and signal the vasculature, via adenosine triphosphate (ATP), to increase capillary flow. We hypothesized that sepsis impaired microvascular au...
The effects of SO2 and H2O on the low-temperature selective catalytic reduction (SCR) activity over MnOx/ZrO2/MWCNTs and MnOx/ZrO2/MWCNTs catalysts modified by Ce or Y was studied. MnCeZr and MnYZr catalysts reached nearly 100% and 93.9% NOx conversions at 200 ◦C and 240 ◦C, respectively. They displayed a better SO2 tolerance, and the effect of H2O was negligible. The structural properties of t...
BACKGROUND Maptaphut Industrial Estate (MIE) was established with a single factory in 1988, increasing to 50 by 1998. This development has resulted in undesirable impacts on the environment and the health of the people in the surrounding areas, evidenced by frequent complaints of bad odours making the people living there ill. In 1999, the Bureau of Environmental Health, Department of Health, Mi...
A reduction in gaseous pollutants is an important method for mitigating PM2.5 concentration the atmosphere, and SO2/NH3/NOx beneficial to control secondary inorganic aerosols PM2.5. In this study, Weather Research Forecasting model with Chemistry (WRF-Chem) was applied study impact on its using scenario simulation Beijing–Tianjin–Hebei (BTH) region. The results showed that BTH region characteri...
Recent studies suggests that air pollution, from among others road traffic, can influence growth and development of the human foetus during pregnancy. The effects pollution heavy industry on birth outcomes have been investigated scarcely. Our aim was to investigate associations outcomes. A cross-sectional study conducted 4488 singleton live births (2012–2017) in vicinity a large industrial area...
Dr. Yusuf G (Debo) Adewuyi is a Professor of Chemical, Biological and Bioengineering Department at North Carolina A&T State University, where his research is in sustainable production of energy & chemical products; synthesis of nanoscale materials for energy and environmental applications; sonochemistry, cavitation and advanced oxidation processes for pollution treatment; liquid-phase chemistry...
The use of fuels, urbanization growth, and economic development have influenced the generation atmospheric pollutants such as NOx (nitrogen oxides), SO2 (sulfur dioxide), TSPs (Total Suspended Particles). Costa Rican industrial sector has different category companies glass melting manufacturing food products clothing, which release emissions these into atmosphere. main objective this research i...
SCR and FGD are making a significant contribution to the control of NOx and SO2 emissions from coal-fired generating units. These technologies are expected to contribute to further reductions in pollutant emissions in response to proposed emission reduction rules. The ability of these technologies to make significant contributions to pollution reduction in a cost-effective manner depends, in pa...
Background & Objectives: The effects of air pollutants on respiratory mortality and morbidity are among the major concerns today. Few studies have been published on the association between mortality and air pollution in Iran. Methods: This study was undertaken in Kerman, Iran. Mortality data was inquired from the Kerman City Health Authority (from March 2006 till Sept 2010) and air pollution da...
