the correlation between serum steroid hormones, testosterone (t), 17β-estradiol (e2), and progesterone (p) and weight of female fishes, biological characteristics of gonad (e.g. fertilization rate, fluid egg rate, gonadosomatic index , polarization index and oocyte diameter) in 10 female of the migratory population of sterlet (acipenser ruthenus) and 5 female of the migratory population of sibe...

A brief review is given on the current transition of electrodeposition materials by a mechanism nucleation followed diffusion-controlled growth. short historical background to study and growth electrocrystallization provided. Then, an outline major potentiostatic transient modeling given, with some comments their relative merits. Finally, summary functions under including theoretical models tha...

Electrochemical impedance spectroscopy (EIS) and in-situ intrinsic resistance measurements were applied to sandwiched disk graphite electrodes to investigate the mechanism of formation of irreversible capacity during initial galvanostatic or potentiostatic lithium intercalation into graphite in four different electrolyte formulations. The stability of the solid electrolyte interphase (SEI) film...

CHARACTERIZATION AND CORROSION OF BCC-TANTALUM COATING DEPOSITED ON ALUMINUM AND STEEL SUBSTRATE BY DC MAGNETRON SPUTTERING by Chirag Joshi Tantalum is one of the most versatile highly refractory corrosion-resistant metals. Tantalum coating can be used as an effective corrosion barrier if it is continuous, free from defects and it adheres well to the substrate. A DC magnetron sputtering techniq...

the dependence of some thermodynamic properties of spin-polarized liquid 3he such as velocity of sound, adiabatic index, isentropic compressibility and temperature on the spin polarization has been investigated along different isentropic paths. the lennard-jones potential has been used in our calculations. it has been found that for higher values of entropy, the spin polarization has greater ef...

in this article, we suggested a novel design of polarization splitter based on coupler waveguide on inp substrate at 1.55mm wavelength. photonic crystal structure is consisted of two dimensional (2d) air holes embedded in inp/ingaasp material with an effective refractive index of 3.2634 which is arranged in a hexagonal lattice. the photonic band gap (pbg) of this structure is determined using t...
