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...

An experiment was conducted to assess the long-term effects of feeding a high Cu diet to sows during gestation and lactation. Fifty-five gilts averaging 152 kg BW and 10.3 mo of age were allotted on d 47 after mating to diets consisting primarily of corn and soybean meal and containing 0 to 250 ppm of added Cu (as CuSO4.5H2O). Both diets contained 8.8 ppm of Cu from the trace mineral mix, and b...

Universal conductance #uctuations in Cu :Mn nano-contacts of di!erent Mn concentrations c yield the phase coherence length ̧ which exhibits a minimum at c+100 ppm. Above this concentration which marks the onset of a spin-glass state below 0.2 K, ̧ depends on the magnetic "eld range, rising to nearly the c"0 value for B3[9.5, 12.5 T] and leveling-o! at a much lower value for B3[0, 3 T]. These re...

Returning crop residues into the soil as a source of organic matter are an important source of copper and can play an important role in the soil fertility. In addition to the role of the organic matter in increasing the concentration of micronutrients in soil solution, attention should be also paid to the role of the kind and the quantity of the root’s exudates released in response to the incor...

Green mussels are marine organisms that threatened due to heavy metal pollution such as lead and copper in waters. In addition, threatening shell metals also a threat symbiont organisms. Bacteria exposed continuously will later be able adapt (resistance) contamination. This study aims determine the concentration of (Pb) (Cu) green from Lampung Bay test resistance symbiotic bacteria Pb Cu well c...

Abstract Availability of micronutrients is one the important factors for successful and economic cultivation vineyards. The objectives this study are to evaluate spatial distribution soil (Cu, Fe, Mn, Zn, B) their suitability vineyard in Jabal Al Arab Syria. To achieve research objectives, samples were collected randomly from farms which cover area. Following this, analyses conducted determine ...

The peripartum (or transition) period is the most-critical phase in the productive life of lactating dairy cows and optimal supply of trace minerals through more bioavailable forms could minimize the negative effects associated with this phase. Twenty Holstein cows received a common prepartal diet and postpartal diet. Both diets were partially supplemented with an inorganic (INO) mix of Zn, Mn,...
