the arghash area is located 45 km to southwest of neyshabour. the subvolcanic rocks in the area consist of biotite hornblende quartz monzodiorite porphyry, hornblende biotite quartz monzodiorite porphyry, hornblende monzonite porphyry, biotite hornblende monzonite porphyry, monzodiorite porphyry and biotite quartz monzodiorite porphyry units. the volcanic rocks consist of hornblende biotite dac...

The research of silica gel manufacturing from cane pulp cinders (Saccharum Officinarum) and the application for Cu (II) ion adsorption has been done. done by some variaties, such as pH, concentration, contact time. result shows optimum pH was 8, concentration 8 ppm, time 75 minutes. perecentage recovery 90,28%, effectivity can be applicated ion.

This study was conducted to determine the effect of Cu deficiency on acute-phase protein concentrations, superoxide dismutase activity, leukocyte numbers, and lymphocyte proliferation in heifers inoculated with live bovine herpesvirus-1 (BHV-1). Hereford × Angus heifers were allotted by weight and initial liver Cu concentrations into molybdenum (Mo)-supplemented (n = 6) or control (n = 6) group...

Abstract This study aimed to determine the optimum conditions for durian skin biomass absorb copper metal (Cu) from its solution. Determination of includes weight, pH biosorption, biosorption contact time, and initial concentration (Cu). adsorbed analyte used Atomic Absorption Spectrophotometry (AAS). In this study, was obtained local waste Parigi Regency, Central Sulawesi Province. The paramet...

Effects of supplemental dietary Zn levels of 0, 50, 500 and 5,000 ppm on the mineral concentration in milk of first- and second-parity sows were evaluated. Colostrum from sows fed 5,000 ppm of supplemental Zn contained less Cu and P than colostrum from sows on the other treatments. Calcium was reduced in the colostrum from sows fed 0 or 5,000 ppm Zn. Copper was reduced and Zn increased in milk ...

A highly luminescent freestanding film composed of the quantum cluster, Au(15), was prepared. We studied the utility of the material for specific metal ion detection. The sensitivity of the red emission of the cluster in the composite to Cu(2+) has been used to make a freestanding metal ion sensor, similar to pH paper. The luminescence of the film was stable when exposed to several other metal ...

Metals are harmful pollutants because they cannot be broken down by living organisms. An excess of metal can become toxic. The in question is copper (Cu). This research aimed to determine the phytoremediation effectiveness Acorus calamus, Pistia stratiotes, and Azolla pinnata as candidates for Cu absorption. investigation employed a wholly random factorial design with two factors: plant absorbe...

Because atmospheric carbon dioxide is the ultimate source of all land-plant carbon, workers have suggested that pCO2 level may exert control over the amount of C incorporated into plant tissues. However, experiments growing plants under elevated pCO2 in both chamber and field settings, as well as meta-analyses of ecological and agricultural data, have yielded a wide range of estimates for the e...
