In this article, jet influence on a gas–solid-multiphase channel flow was experimentally and numerically studied. The jet flow was found to have a diameter-selective controlling effect on the particles’ distribution. Jet flow formed a gas barrier in the channel for particles. While tiny particles could travel around and large particles could travel through, only particles on the 10 -mm s…
To estimate the effect of social factors in the neighborhood environment on suicide risks, we studied 392 suicides and 416 controls, all aged 15–34 years, consecutively and randomly selected from 16 rural counties in three provinces of China. The social factors in the village neighborhood were measured by the WHO scale of Community Stress and Problems. The individual scores as well as the sum…
We examined the Acute Myocardial Infarction (AMI) incidence and mortality rates in New York State for a recent 13-year period. Hospital discharge data and death certificate information are combined to create patient episodes for AMI. Trends in the risk-adjusted AMI incidence and mortality are examined for the years 1996 through 2008. Between 1996 and 2008, the AMI incidence rate declined by 35…
Abstract. Clays intercalated with both organic cations and hydroxy-metal cations, also known as inorganic–organic clays (IOCs), have drawn great interests in the recent years because they possess the properties of both organoclays and pillared layered clays (PILCs). In this work, cetyltrimethyl ammonium bromide (CTMAB) and hydroxy-aluminum ([Al13O4(OH)24(H2O)12]7+ or Al13) were selected a…
The aim of this study was to demonstrate the use of thermogravimetric analysis (TGA) as a potential screening method for monitoring biodiesel production by transesterification of soybean oil with methanol. Soybean oil and commercially available biodiesel were mixed in varying proportions by weight as standards. In addition, mixtures of different biodiesel/soybean oil ratios were also created b…
There is evidence that climate change induced tree mortalities in boreal and temperate forests and increased forest turnover rates (both mortality and recruitment rates) in Amazon forests. However, no study has examined China’s tropical and subtropical evergreen broadleaved forests (TEBF) that cover >26% of China’s terrestrial land. The sustainability of this biome is vital to the maintenan…
To investigate the effects of multiple environmental conditions on greenhouse gas (CO2, N2O, CH4) fluxes, we transferred three soil monoliths from Masson pine forest (PF) or coniferous and broadleaved mixed forest (MF) at Jigongshan to corresponding forest type at Dinghushan. Greenhouse gas fluxes at the in situ (Jigongshan), transported and ambient (Dinghushan) soil monoliths were measured usi…
