Dense deposit disease (DDD) is an orphan disease that primarily affects children and young adults without sexual predilection. Studies of its pathophysiology have shown conclusively that it is caused by fluid-phase dysregulation of the alternative pathway of complement, however the role played by genetics and autoantibodies like C3 nephritic factors must be more thoroughly defined if we are to ...

Ellipsoid or geometric anisotropy is a widely used method in geostatistical analysis to obtain variograms with different ranges directions (azimuth) and relatively similar sill variance. indispensable mining when resource geologist intends understand the spatial continuity of variables related any geological controls mineralization. For example, dealing mineralization tabular deposits, porphyri...

Oxide materials require high dopant activation for applications and may be easily contaminated by hydrogen impurities. In this work, the dynamics of substitutionals in zinc oxide, both predicted measured, are presented ascertaining that can act to remove free carriers added electron donors, such as aluminum. This is spite evidence itself an donor. Flow-limited field-injection electrostatic spra...

The northern flank of the North China Craton (NCC) hosts a linear zone gold, molybdenum, silver, lead, and zinc polymetallic ore deposits. Among these, Yingfang Pb-Zn-Ag deposit is located in central part Yanshan–Liaoxi metallogenic belt (YLMB) which extends for approximately 1000 km forms major mineralized zone. In this study, we characterize mineralization trace genesis based on new sulfur le...

Yeylagh-e-Gharechi porphyry copper deposit is located in the Arasbaran metallogenic belt at northwestern Iran, 25 kilometer of Ahar. Porphyry mineralization at the Yeylagh-e-Gharechi deposit occurred in post-Oligocene quartz monzonite and monzonite bodies which was hosted by Eocene volcanic rocks. Mineralization occurred as veins, veinlets and dissemination in hypogene zone. Supergene zone has ...
