To analyze the geological occurrence and predict the drainage performance of coalbed methane in the central Hunan depression of China, coal samples were collected to conduct physical experiments and numerical simulations. The following conclusions were reached. The vitrinite ranges from 54.37 to 87.80%, the inertinite is between 11.14–25.89%, and exinite is less than 1%. The inorganic components are mainly clay minerals and vary from 0.71 to 5.66%. The major porosity ranges from 7 to 9%, and it is influenced by organic/inorganic components and maturity. Both the vertical and horizontal permeabilities are at a relatively low level, mostly below 0.05 mD, indicating the reservoir is low permeable or non-permeable. The reservoir pressure ranges from 3.74 to 11.58 MPa, which has significant and positive linear correlations with closure pressure and burial depth. Gas content varies from 5 m3/t to 20 m3/t. The theoretical recovery ratio in the Hongshandian mining area is about 61.7%, while the values of the two spots in the Duanpiqiao mining area are 49.1 and 54.5%. Production predictions show that under the permeability of 0.01 mD, 0.05 mD, and 0.10 mD, cumulative gas productions in 10 years for a single well range from 1.7 × 106 m3 to 3.2 × 106 m3, and those for a well group consisting of five wells vary from 10.5 × 106 m3 to 19.2 × 106 m3. Thus, this area will have a high value for coalbed methane exploitation after stimulating the reservoir to increase permeability successfully.

Community-engaged interventions are particularly important in the context of viral hepatitis. Social determinants of hepatitis contribute to uptake of hepatitis-related services across the care continuum, suggesting the need for community-based interventions. Most literature reviews on hepatitis have focused on biomedical components and not on public health interventions. The purpose of this project is to identify and assess community-engaged viral hepatitis interventions using a global scoping review.

Despite great advances in lipid-lowering therapy, the gender-based disparities in lipid goal success among Chinese coronary heart disease (CHD) patients receiving lipid-lowering treatment remained uncharacterized. Furthermore, little is known about potential causes for this gender imbalance. This cross-sectional trial included 25 697 patients treated with lipid-lowering agents from 122 centres between April 2012 and October 2012; data for 9420 participants with CHD were analysed in the present study; all underwent clinical examination and had their latest fasting lipid profiles while on lipid-lowering therapy recorded. Logistic regression was used to explore possible factors associated with gender disparity in goal attainment rates, and to what extent each factor contributes. Of 9420 CHD patients (42.5% women) evaluated, women had a significantly lower overall low-density lipoprotein cholesterol (LDL-C) success rate than men (46.2 vs. 62.7%, P < 0.0001). Among CHD patients with diabetes, only 31.5% of women and 46.4% of men ( P < 0.0001) attained the optional LDL-C target of

The mesh data structure, one of the fundamental data structure within the parallel framework, its design and realization level have an effect upon parallel capability of the parallel framework. Through the architecture and the fundamental data structure within some typical parallel framework relatively analyzed, such as JASMIN, SIERRA, and ITAPS, the design thought of parallel framework is discussed. Through borrowing ideas from layered set of services design about the SIERRA Framework, and combining with the objective of PANDA Framework in the near future, this paper present the rudimentary system about PANDA framework layered set of services. On this foundation, detailed introduction is placed in the definition and the management of the mesh data structure that it is located in the underlayer of the PANDA framework. The design and realization about parallel distributed mesh data structure of PANDA are emphatically discussed. The PANDA framework extension and application program development based on PANDA framework are grounded on our efforts.
