In this research nickel zinc ferrite nanoparticles with composition of Ni1-xZnxFe2O4 (where x=0, 0.3, 0.7, 1) were synthesized by a sol-gel method at 600 °C for 5 hours. The structure of nanoparticles was studied using X-ray diffraction pattern. The lattice parameter of ferrite nanoparticles was calculated and indicates lattice constant of nanoparticl...

saffron (crocus sativus l.) has been considered as a medicinal plant since ancient times and also widely used as food additive for its color, taste and odor. the pharmacological properties of saffron and its main constituents, crocin and safranal have been evaluated using different in vivo and in vitro models. additionally, other lines of studies have found toxicological effects of saffron.  ho...

The effects on sucrose yield of varying the time interval between Ethrel and Fusilade Super applications in a combination treatment were tested on variety NC0376. Results suggested that Ethrel applied 12 weeks, and Fusilade Super applied eight weeks before harvesting were the most beneficial. Other varieties which responded to a combination treatment were N19, N12 and N22. Varieties N14, N19, N...

The article presents an analysis of the results experimental studies effect different types a super absorbent polymer additive on strength concrete. study is aimed at effectiveness new type in concrete structures. In course full-scale experiments, it was possible to identify optimum dosage SAP for fine-grained and heavy concretes. addition, showed that remains unchanged if (SAP) 0.5% weight cem...

A two dimensional numerical model of shallow water equations was developed tocalculate sub and super-critical open channel flows. Utilizing an implicit scheme the steady stateequations were discretized based on control volume method. Collocated grid arrangement was appliedwith a SIMPLEC like algorithm for depth-velocity coupling. Power law scheme was used fordiscretization of convection and dif...

This study is focused on fabrication and characterization of mixed matrix poly ether sulfone based nanofiltration membrane by phase inversion method. The effect of different amounts of Ilmenite (FeTiO3) particles as inorganic filler additive in the casting solution on physic-chemical characteristics of membranes was studied. Scanning electron microscopy, surface analysis, water content, contact...
