In gold-endowed greenstone belts, ore bodies generally correspond to orogenic gold systems (OGS) formed during the main deformation stage that led craton stabilization (syntectonic period). Most OGS deposits postdate and locally overprint magmatic-hydrothermal systems, such as Au-Cu porphyry mostly magmatic (synvolcanic period) polymetallic intrusion-related (IRGS) of syntectonic period. Porphy...

Approximately 90% of all head and neck malignancies and 94% of oral malignancies are squamous cell carcinoma (SCC). Tobacco smoking is considered as the most important causative agent for SCC. Despite aggressive and multidisciplinary treatment approaches, there has been no significant improvement in 5-year survival over the past 20 years. Several prognostic and predictive clinical, pathological...

The energy change per electron in a chemical or physical transformation, ΔE/n, may be expressed as Δχ̅ + Δ(VNN + ω)/n, where Δχ̅ is the average electron binding energy, a generalized electronegativity, ΔVNN is the change in nuclear repulsions, and Δω is the change in multielectron interactions in the process considered. The last term can be obtained by the difference from experimental or theoreti...

Porphyry deposits are copper-rich orebodies formed by precipitation of metal sulphides from hydrothermal fluids released from magmatic intrusions that cooled at depth within the Earth's crust. Finding new porphyry deposits is essential because they are our largest source of copper and they also contain other strategic metals including gold and molybdenum. However, the discovery of giant porphyr...

Deep-seated mineralization prediction is an important scientific problem in the area of mineral resources exploration. The 3D metallogenic information extraction geology and geochemistry can be great help. This study uses modeling technology to intuitively depict spatial distribution orebodies, fractures, intrusive rocks. In particular, geochemical models 12 elements are established for extract...

Despite the existence of a well-known set forecast and search criteria, only three gold silver epithermal deposits were discovered on territory Amguem-Kanchalan metallogenic zone, which has significant resource potential. The base enterprises developing them is extremely limited. aim study to clarify regional local conditions for localization gold-silver mineralization, forecasting searching pr...

To study the Sustained Low Efficiency Dialysis (SLED) in treatment of end-stage renal disease with refractory heart failure and clinical curative effect hypertension. choose department Nephrology, third People's Hospital Gansu Province 54 cases failure. The patients intractable hypertension were randomly divided into control group observation group, 27 each group. was treated Intermittent HemoD...
