To study the effect of micronutrients and irrigation cutback at different development stages on vegetative characteristics and yield of pinto bean (Talash cultivar), an experiment was carried out at Agricultural Research Station of Khoy in 2009. This experiment was performed as strip split plots based on randomized complete blocks design with 3 replications. Treatments included irrigation as th...

any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...

in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...

in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...

asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...

In order to study the effects of cycocle and plant growth promoting rhizobacteria (PGPR) on yield, Chlorophyll fluorescence parameters and some physiological traits of wheat under water limitation condition, a factorial experiment based on randomized complete block design with three replications was conducted at the research farm of faculty of agricultural sciences, University of Mohaghegh Arda...
