Tribasic copper chloride (TBCC) has been shown to have better bioavailability than copper sulfate pentahydrate (CS) when fed at levels in excess of the requirement. Our objective was to determine if this relationship holds at levels below the Cu requirement. After depleting Cu levels for 7 d, 3 pens of 4 chicks/pen were fed a purified diet or a sorghumsoy diet supplemented with either 0, 1, 3, ...

The Sonju Lake intrusion (SLI) is a 1200-m thick, sheet-like, tholeiitic layered intrusion located within the 1096 Ma Beaver Bay Complex of NE Minnesota. Its cumulus stratigraphy of Ol Pl+Ol Pl+Cpx+Ol Pl+Cpx+Ox±Ol Pl+Cpx+Ox+Ol+Ap indicates formation by closed-system fractional crystallization of a tholeiitic magma. In 1999, outcrop sampling revealed a stratiform PGE-enriched interval within oxi...

Effective and inexpensive adsorbents are needed for wastewater treatment. This study describes the use of Cu/natural zeolite as an adsorbent in adsorption remazol black b dye terms kinetics isotherms. Cu/zeolite was obtained by activating natural using HCl NH4Cl solution then impregnated Cu(NO3)2.3H2O solution. Characterization XRD, SEM-EDX tools. Adsorption with a batch system carried out at v...

Porphyry Cu-Mo deposits are among the world’s largest source of Cu, Mo, and Re, also an important other trace elements, such as Au Ag. Despite fact that chalcopyrite, bornite, pyrite most common sulfides in this deposit type, their element content remains poorly constrained. In particular, little is known about minor elements partitioning into Cu-(Fe) a function temperature pH hydrothermal flui...

In this work, silver nanoparticles (Ag NPs) were decorated on thiol (-SH) grafted graphene oxide (GO) layers to investigate the antibacterial activities in Gram-positive bacteria (Staphylococcus aureus) and Gram-negative bacteria (Pseudomonas aeruginosa). The quasi-spherical, nano-sized Ag NPs were attached to the GO surface layers, as confirmed by using field emission scanning electron microsc...

Trace element compositions of sphalerite and chalcopyrite have been investigated for four arc-hosted Cretaceous VMS deposits (María Teresa, Perubar, Palma in Peru, Cerro de Maimón the Dominican Republic) using laser ablation inductively-coupled plasma mass spectrometry. In sphalerite, Fe, Mn, Cd, Hg, Ag, Sb, Se, In, Ge, Ga are lattice-bound, whereas Sn, Tl, Bi, Pb occur at least partly as miner...

This study determined the nutritive value of Indigoferra gerardiana, Marisine affricana, Impashion bicolor and Adhatoda vesica shrubs for ruminants. Chemical analysis revealed that dry matter (DM) content varied from 22.2% (Dodonia viscosa) to 33.6% (Debregeasia salicifolia). Maximum crude protein (19.8%) was observed for Anisomoles indica, while, neutral detergent fiber was greater (67%) in Do...

This study was conducted to estimate the heavy metal pollution in groundwater, soil, fruits, and vegetables within cement industry its vicinity. Seven different fruits seven metals (Cd, Zn, Ni, Co, Cu, Cr, Mn) were selected for analysis fruit, vegetable samples by atomic absorption spectrometry (AAS). Results of this compared with National International Standards Pak NSWQD, WHO, USEPA. The pH s...

Increasing functional complexity and dimensional compactness of electronic devices have led to progressively higher power dissipation, mainly in the form of heat. Overheating of semiconductor-based electronics has been the primary reason for their failure. Such failures originate at the interface of the heat sink (commonly Cu and Al) and the substrate (silicon) due to the large mismatch in ther...
