Comparative Study of Gacun and Youre Silver–Lead–Zinc–Copper Deposits in Sichuan, SW China, and their Mineralization Significance
ore-bearing horizon structure of ore-bearing belt VMS deposit Gacun–Youre ore district
2018/4/10
The large Gacun silver–lead–zinc–copper deposit in Sichuan Province is one of the largest volcanogenic massive sulfide (VMS) deposits in China. The deposit consists of western and central ore bodies, ...
Effect of the application of bioplexes of zinc, copper and manganese on milk quality and composition of milk and colostrum and some indices of the blood metabolic profile of cows
dairy cows bioplexes of zinc copper and manganese colostrum milk blood
2015/6/4
The object of an experiment was inorganic and organic forms of zinc, copper and manganese applied in mineral mixtures to dairy cows. The experiment was carried out on 90 cows with average milk yield f...
Lithospheric-scale structures in New Guinea and their control on the location of gold and copper deposits
Lithospheric-scale structures New Guinea location of gold copper deposits
2015/1/6
The locations of major gold and copper deposits on the island of New Guinea are considered by many to be controlled by a series of transfer faults that strike N–S to NE–SW, perpendicular to the long a...
Molecular-dynamics Simulations of Stacking-fault-induced Dislocation Annihilation in Pre-strained Ultrathin Single-crystalline Copper Films
Molecular dynamics dynamic deformation metal structure
2014/12/19
We report results of large-scale molecular-dynamics (MD) simulations of dynamic deformation under biaxial tensile strain of pre-strained single-crystalline nanometerscale- thick face-centered cubic (f...
The sorption and desorption of phenanthrene and pyrene on treated and untreated aspen wood fibers were studied to evaluate the sorption mechanisms of polycyclic aromatic hydrocarbons (PAHs). Those sam...
Salt Lake City’s Urban Growth and Kennecot Utah Copper: A Geographical Analysis of Urban Expansion onto a Previously Proposed Superfund Site Adjacent to the World’s Largest Copper Mine
Salt Lake City’s Urban Growth Kennecott Utah Copper Urban Expansion Adjacent to the World’s Largest Copper Mine
2014/10/20
Kennecott copper mine is one of the largest producers of pollution in the United States: it has contaminated over 72 square miles in the Salt Lake Valley. In 1998 alone, Kennecott, which is located on...
Effects of a Chelated Copper as Growth Promoter on Performance and Carcass Traits in Pigs
Chelated Trace Mineral Cu(HMTBa)2 Copper Growth Promoter Swine
2016/5/16
Three studies were conducted to investigate whether a chelated Cu can replace CuSO4 as a growth promoter in pigs. In Exp. 1, a total of 240 piglets (Large White×Landrace, 7.36±0.10 kg) were randomly a...

Iron and copper limitations differently affect growth rates and photosynthetic and physiological parameters of the marine diatom Pseudo-nitzschia delicatissima
Iron and copper limitations differently affect growth rates photosynthetic and physiological parameters marine diatom Pseudo-nitzschia delicatissima
2014/4/2
In ～ 50% of the ocean, iron (Fe) limits phytoplankton growth, including that of the diatom Pseudo-nitzschia. Fe-limited Pseudo-nitzschia spp. may produce the potent neurotoxin domoic acid (DA) to acce...
