In Santa, increasing use agrochemicals is disturbing, as farmers have little or no idea about application techniques effects these chemicals on environment. The objective this work was to determine knowledge pesticides fertilize...

While there is a considerable body of research on the abundance and behavior of inositol hexakisphosphate in soils, much less is known regarding its behaviour in aquatic systems. The observed physico-chemical behaviour of this organic P species suggests that in marine and freshwaters, it should be complexed and precipitated by major ions such as calcium, magnesium, iron or aluminium, and thus i...

introduction: the aim of this study was to evaluate the correlation between serum levels of ovarian and gonadotropin hormones, age and number of follicles with follicular alkaline and acid phosphatase activity in infertile women under controlled ovarian hyperstimulation. methods: after collection of follicular fluid and calculation of the number of follicles, the specific activity of alkaline (...

conclusions in conclusion, dietary counseling of patients on hd is mandatory. interventions that consider the socio-economic situation allow delivering important messages on foods with the least amount of p and adequate protein content, and they may be a successful strategy in targeting patients at a higher risk of hyperphosphoremia. results results showed serum p level was reduced in patients ...

A triazole-linked hydroxyethylimino conjugate of calix[4]arene () and its cadmium complex have been synthesized and characterized, and their structures have been established. In the complex, both the Cd(2+) centers are bound by an N2O4 core, and one of it is a distorted octahedral, whereas the other is a trigonal anti-prism. The fluorescence intensity of the di-nuclear Cd(ii) complex is quenche...
