毕摩文化是彝族宗教文化的核心,是传承和延续彝族优秀文化的保障,是中华传统文化的重要组成部分。随着经济社会的发展,毕摩文化的传承出现了前所未有的危机。为更好传承发展毕摩文化,笔者通过对喜德县和西昌市等地的实地调查,并结合毕摩个别访谈的方式,发现凉山毕摩文化传承受市场缩减、毕摩收益不理想等原因的影响,毕摩和毕惹(徒弟)群体骤减、仪式水平逐步失去内涵,导致毕摩文化传承面临断层的风险。笔者就当下如何更好地传承毕摩文化进行讨论与思考。

Geochemical Assessment for Morendat East Geothermal Prospect, Using Radon and Carbondioxide Concentration from Soil, Kenya

引用

Journal of Geological Resource and Engineering 2017年第1期5卷 38-47页

作者： Jesca muga Ministry of Energy and Petroleum P.O. Box 30582-00100 Nairobi Kenya

Geochemical assessment was carried out at the Morendat East geothermal prospect by characterizing radon （22~Rn） and Carbondioxide （CO2） concentration levels from soil-gas survey. The primary aim was to locate permeable zones and infer the presence of possible heat source linked to an active geothermal system. The secondary aim was to rank the prospect and facilitate its development by the private sector. This study focused on the distribution of Radon and Carbon dioxide concentration levels in the soil cover within Morendat East area located in Nakuru County. The area was considered as having potential for geothermal resource hence earmarked for study in the financial Year 2014/2015 by the Ministry of Energy and Petroleum. The location is characterized by scarcity of surface geothermal manifestations hence soil gas survey was considered appropriate for the study. Random sampling method was used and resulted in sampling 100 points in an area of about 90 km^2. CO2 concentration measurements were done using an Orsat gas sampling apparatus whereas ^220Rn gas concentrations were measured using a portable radon detector. The CO2 values ranged from 0-5.4% while the ^220Rn ranged from 0-2,834 counts per minute （cpm）. Possible faults were inferred north of the prospect area due to the anomalously high levels of CO2 and ^220Rn recorded.

Alcohol use disorder and its impact on chronic hepatitis C virus and human immunodeficiency virus infections

引用

World Journal of Hepatology 2016年第31期8卷 1295-1308页

作者： Daniel Fuster Arantza Sanvisens Ferran Bolao Inmaculada Rivas Jordi Tor Robert muga Department of Internal Medicine Addiction Unit Hospital Univer-sitari Germans Trias i Pujol Department of Internal Medicine Hospital Univer-sitari de Bellvitge IDIBELL Municipal Center for Substance Abuse Treatment (Centro Delta) IMSP

Alcohol use disorder(AUD) and hepatitis C virus(HCV) infection frequently co-occur. AUD is associated with greater exposure to HCV infection, increased HCV infection persistence, and more extensive liver damage due to interactions between AUD and HCV on immune responses, cytotoxicity, and oxidative stress. Although AUD and HCV infection are associated with increased morbidity and mortality, HCV antiviral therapy is less commonly prescribed in individuals with both conditions. AUD is also common in human immunodeficiency virus(HIV) infection, which negatively impacts proper HIV care and adherence to antiretroviral therapy, and liver disease. In addition, AUD and HCV infection are also frequent within a proportion of patients with HIV infection, which negatively impacts liver disease. This review summarizes the current knowledge regarding pathological interactions of AUD with hepatitis C infection, HIV infection, and HCV/HIV co-infection, as well as relating to AUD treatment interventions in these individuals.

Effects of holmium and hot-rolling on microstructure and mechanical properties of Mg-Li based alloys

引用

Journal of Rare Earths 2016年第12期34卷 1269-1276页

作者：穆佳郭浩邹云许松松张中武 Key Laboratory of Superlight Materials and Surface Technology Ministry of Education College of Materials Science and Chemical Engineering Harbin Engineering University

A rare earth holmium（Ho） element was introduced into Mg-8Li-3Al alloy to investigate the effects of holmium and hot-rolling on the microstructure and mechanical properties of the Mg-Li based alloys. Both alloys with and without Ho showed a duplex structure with α and β phases. The as-cast Mg-8Li-3Al alloy exhibited a yield strength（YS） of 111.1 MPa, ultimate tensile strength（UTS） of 148.2 MPa and an elongation of 9.50% while the hot-rolled Mg-8Li-3Al-3Ho alloy had a yield strength of 249.7 MPa, ultimate tensile strength of 293.1 MPa with an elongation of 21.40%. These results indicated that both strength and ductility could be significantly enhanced by addition of holmium together with thermo-mechanical treatment. It was found that the microstructure could be refined significantly and the fracture modes changed from partial brittle to ductile fracture due to the addition of holmium. The effects of microstructure refinement, work hardening and solid solution strengthening induced by the addition of holmium and hot-rolling on the mechanical properties were discussed.
