Survival and disease burden analyses of occupational pneumoconiosis during 1958-2021 in Huangshi city, China: a retrospective cohort study.

Background: Pneumoconiosis, a chronic disease stemming from prolonged inhalation of dust particles, stands as a significant global burden of occupational diseases. This study aims to investigate the survival outcomes of pneumoconiosis patients in Huangshi city, China, while also evaluating the disease burden on afflicted patients.

Methods: Data for this study were sourced from the Huangshi Center for Disease Control and Prevention.

Association between long-term exposure to ambient air pollutants and the risk of tuberculosis: A time-series study in Nantong, China.

Background: Increasing evidence has shown that the risk of tuberculosis (TB) might be related to the exposure to air pollutants; however, the findings are inconsistent and studies on long-term air pollutant exposure and TB risk are scarce. This study aime to assess the relationship between monthly exposure to air pollution and TB risk in Nantong, China.

Methods: We collected the time series data on the number of TB cases, as well as environmental and socioeconomic covariates from January 2005 to December 2020.

Population-level health and economic impacts of introducing Vaccae vaccination in China: a modelling study.

Introduction: Given the ageing epidemic of tuberculosis (TB), China is facing an unprecedented opportunity provided by the first clinically approved next-generation TB vaccine Vaccae, which demonstrated 54.7% efficacy for preventing reactivation from latent infection in a phase III trial. We aim to assess the population-level health and economic impacts of introducing Vaccae vaccination to inform policy-makers.

Combined impacts of environmental and socioeconomic covariates on HFMD risk in China: A spatiotemporal heterogeneous perspective.

Background: Understanding geospatial impacts of multi-sourced influencing factors on the epidemic of hand-foot-and-mouth disease (HFMD) is of great significance for formulating disease control policies tailored to regional-specific needs, yet the knowledge is very limited. We aim to identify and further quantify the spatiotemporal heterogeneous effects of environmental and socioeconomic factors on HFMD dynamics.

Methods: We collected monthly province-level HFMD incidence and related environmental and socioeconomic data in China during 2009-2018.

Theoretical studies of "stabilizing" behavior about carbon nanotubes under the electrostatic force.

We study the dispersion and stability of carbon nanotube (CNT) suspensions under the electrostatic interactions. The potential energies of van der Waals (vdW) attractions between the CNT themselves are obtained on the continuum Lennard-Jones (LJ) model. The potential energies of electrostatic repulsions are based upon the Yukawa-segment model.

(2R,4R)-3-(tert-But-oxy-carbon-yl)-2-(3-chloro-phen-yl)-1,3-thia-zolidine-4-carb-oxy-lic acid monohydrate.

In the title compound, C(15)H(18)ClNO(4)S·H(2)O, the thia-zolidine ring displays a half-chair conformation. In the crystal, the water mol-ecules are linked to the organic acid mol-ecules via inter-molecular O-H⋯O hydrogen bonds.

Investigation on activated semi-coke desulfurization.

An activated semi-coke with industrial-scale size was prepared by high-pressure hydrothermal chemistry activation, HNO3 oxidation and calcination activation in proper order from Inner Mongolia Zhalainuoer semi-coke, which is rich in resource and cheap in sale. SO2 adsorption capacity on this activated semi-coke was assessed in the fixed bed in the temperature range of 60-170 degrees C, space velocity range of 500-1300 h(-1), SO2 concentration of 1000-3000 ppmv, and N2 as balance. The surface area, elemental and proximate analysis for both raw semi-coke and activated semi-cokes were measured.
