In the reaction of zinc(II) sulfate and chloride salt 2-acetylpyridine-aminoguanidine, two types complex were obtained, i.e., [Zn(H2O)6](H2L)2(SO4)3·3H2O [Zn(L)H2O(SO4)]·H2O, depending on presence LiOAc as deprotonating agent. The physicochemical, structural, photoluminescence properties complexes examined. first complex, obtained in absence LiOAc, Schiff base had role a counter-ion its doubly ...

The effect of seven rates viz. 0 (control), 5, 10 25, 50, 75 and 100 ml/Kg of treated distillery effluent on the physico-chemical properties of soils was studied under natural environment in pot experiment. The characteristics of the soil were determined before and after 12 weeks of effluent irrigation. The results revealed that the 100% concentration of distillery effluent decreased BD (5.63%)...

Functional evaluation of chemically modified human erythrocytes has led to the proposal that amino acid residue E681 of the band 3 anion exchanger AE1 lies on the anion translocation pathway and is a proton carrier required for H+/SO4(2-) cotransport. We have tested in Xenopus oocytes the functional consequences of mutations in the corresponding residue E699 of mouse AE1. Most mutations tested ...

The effect of paper mill effluent on the physico-chemical properties of soils was studied under natural environment in pots experiment. The soil was treated to six rates of effluent viz. 5, 10 25, 50, 75 and 100 ml/Kg soil. The physico-chemical properties of the soil were determined before and at the end of the experiment, 12 weeks after irrigation with the effluent. Results revealed that among...

Mehlich-3 (M-3) is used as a universal nutrient extractant due to its ability simultaneously extract multiple elements. This study aimed assess M-3 for the simultaneous determination of plant-available zinc (Zn), copper (Cu), iron (Fe), manganese (Mn), boron (B), and sulfate (SO4-S) in soil amended with switchgrass- (SGB) poultry litter-derived biochars (PLB), which were vary pH values (5.7–7.6...

Abstract Groundwater contamination due to nutrient from inefficient fertilization processes can reduce oil palm productivity. In overcoming this problem, a simple and low-budget method, namely trunk injection, was applied maintain the productivity of plants environmentally friendly. Therefore, injection as method increase quantity quality bunch average weight support sustainable management grou...

background: the present study was performed to investigate the effects of trace elements particularity se, zn and cu on tumor genesis in breast cancer. methods: the inhibitory effect of se, zn and cu, on telomerase activity was analyzed in human breast tumor tissues and breast cancer (t47d) cells. tissue specimens from 24 women with benign breast disease and 32 women with breast cancer specimen...

The purpose of this study is to analyze the chemical composition of wet precipitation in samples collected at three stations in the Candiota region in the Brazilian state of Rio Grande do Sul (RS). Samples were collected in 2004. Variables analyzed in wet precipitation were pH, conductivity, and concentration of Cl-, NO3-, SO4(2-) F-, Na+, Ca2+, Mg2+, K+, NH4+, Cu, Zn, Fe, Mn, Pb, Ni, Cd, Co, a...
