The search for hidden minerals with a large, buried depth depends on the guidance of geological and metallogenic theory, but it is difficult to master characteristics deep deposits. In this paper, taking survey area as an example, stimulated polarization geophysical method used obtain information indirectly. Through analysis study IP (induced polarization) anomaly its in tin polymetallic mining...

BACKGROUND Bone status in HIV-infected patients on antiretroviral treatment (ART) is poorly documented in resource-limited settings. We compared bone mineral density between HIV-infected patients and control subjects from Dakar, Senegal. METHODS A total of 207 (134 women and 73 men) HIV-infected patients from an observational cohort in Dakar (ANRS 1215) and 207 age- and sex-matched controls f...

In August 2002, the Geological Survey Branch (GSB) of the Ministry of Energy and Mines was asked by the Ministry of Sustainable Resource Management to undertake a Level 2 Mineral Resource Assessment (MRA) of the Coast Information Team’s (CIT) project area which encompasses approximately 11 million hectares. This was followed by a similar request in February 2003 to do the Lillooet Land Resource...

China proposes to construct green mines as one of the significant means elevate degree mining industry and protect environment. This paper constructs six evaluation indicators, namely mine environment, Resource development mode, Comprehensive utilization resources, Energy conservation emission reduction, Technological innovation digital mining, Enterprise management corporate image, reflect fir...

In mineral resource evaluation a careful analysis and assessments of the geology, assay data and structural data is performed. One important question is where to position the exploration boreholes, another is what method to use when analyzing the grade in the collected material. Here, a challenge of this type is whether one should analyze the collected core samples with accurate and expensive l...

Current occupational exposures to man-made mineral fibers (MMMF), including refractory ceramic fibers (RCF), were measured as part of an exposure assessment program for an epidemiological study pertaining to cancer and mortality patterns of Ontario construction workers. The assessments were carried out at commercial and residential sites. A total of 130 MMMF samples (104 personal and 26 area) w...
