Nowadays, social activities in the real world (e.g., meetings, discussions, parties) are more and more popular and important to human life. As the number of contacts increases, the implicit social graph becomes increasingly complex, leading to a high cost on social activity organization and activity group formation. In order to promote the interaction among people and improve the efficiency of ...

the aim of this study was to determine the extent of metal pollutions and the identification of their major sources in the vicinity of the sangan iron mine occurring in ne iran. soil samples were collected from the vicinity of the mine site and analyzed for heavy metals. in addition, the chemical speciation of these metals was investigated by means of the sequential extraction procedure. the st...

the quality of hg contaminated sediments in artisanal gold mining areas of tanzania have to date only been assessed through bulk chemical analysis. however, measurement of contaminant levels alone has a limited ability to predict adverse effects on living resources. in this study we investigated the possible effects of hg contaminated sediments from the river mabubi which drains the artisanal g...

Mining chemical compounds in silico has drawn increasing attention from both academia and pharmaceutical industry due to its effectiveness in aiding the drug discovery process. Since graphs are the natural representation for chemical compounds, most of the mining algorithms focus on mining chemical graphs. Chemical graph mining approaches have many applications in the drug discovery process tha...

A new quantitative index to analyse the corporate social responsibility (CSR) level of mine sites was developed, providing an easy and friendly tool apply a continuous improvement approach CSR levels, being able involve all potential stakeholders. The can be used in any type project stage: prospecting exploration, development, mining, processing, closure rehabilitation. system consists two dime...

The potential effects of proposed lead-zinc mining in an ecologically sensitive area were assessed by studying a nearby mining district that has been exploited for about 30 y under contemporary environmental regulations and with modern technology. Blood and liver samples representing fish of three species (largescale stoneroller, Campostoma oligolepis, n=91; longear sunfish, Lepomis megalotis, ...

Considering the unfortunate skill of English teaching posts, this paper advances plan strategy for postcapability assessment framework in light data mining, further develops equipment arrangement, upgrades activity cycle and capability programming, builds postability framework. At long last, it is affirmed by tests. The view mining has high practicability during time spent down to earth applica...

Issues about privacy-preserving data mining (PPDM) have emerged globally. The recent proliferation in PPDM techniques is evident. Motivated by the increasing number of successful techniques, the new generation in PPDM moves on toward standardization because it will certainly play an important role in the future of PPDM. In this paper, we lay out what needs to be done and take some steps toward ...

From the modest beginning in 1948, the atomic energy programme of India has grown to vast dimensions with mosaic of many interrelated programmes. The uranium ore mining and processing industry of the country began at Jaduguda in 1968. It has made a very impressive growth during these years with four operating mines and meeting the entire fuel requirement of the country. The country now has a de...
