Effects of photoperiod on growth, eating patterns and clearance rate, secretion rate and half-life of growth hormone in serum were assessed in Holstein heifers. Sixty-four prepubertal heifers (avg body wt 102 kg) were blocked by weight into four groups of 16. Within block, each animal was randomly assigned to one of four photoperiod treatments: 16 h of cool-white fluorescent light:8 h dark (CW-...

the effects of different grazing intensities on the above and underground biomass of twospecies festucaovina l. and alopecurustextilisboiss. in the north sabalan rangelands (in shabil) were investigated. sampling on the light, medium and heavy grazing intensities in the flowering stage (the second half of june 2013) were performed. initially, from a 90-meter transects perpendicular to the slope...

Given any simple Lie superalgebra g, we investigate the structure of an arbitrary simple weight g-module. We introduce two invariants of simple weight modules: the shadow and the small Weyl group. Generalizing results of Fernando and Futorny we show that any simple module is obtained by parabolic induction from a cuspidal module of a Levi subsuper-algebra. Then we classify the cuspidal Levi sub...

 Environmental enrichment is one of the methods for improving fish growth performance. In the present trial, the effects of both light color and music on growth performance and survival of goldfish (Carassius auratus) (initial mean weight: 4.15±0.08 g) were investigated for 2 months. Two light color treatments (red light and white light) and three music treatments (M0: without music, M30:30 min...

The reaction of hydrogen peroxide and  pheny -9-acridinecarboxylate in the presence of rhodamin B as a fluorophore leads to the emission of either bright blue light  or bright red light, depending on the structure of fluorescer and reaction conditions. The light emitter responsible for the Chemi Luminescence (CL) reaction is acridone and that the blue light produced with out the fluorescers...

In this work, a novel thinner derived from natural botany Chinese Larch Tree was obtained by combination lignin with phenol using H2O2 as oxidant and the acting efficiency of lignosulfonate in the drilling fluids is greatly enhanced after oxidation with H2O2. Both the chemical structure and the adsorptive ability of the oxidation...

An intrinsic optical-fiber sensor based on Faraday Effect is developed that is highly suitable for measuring lightning current on aircraft, towers and complex structures. Originally developed specifically for aircraft installations, it is light-weight, non-conducting, structure conforming, and is immune to electromagnetic interference, hysteresis and saturation. It can measure total current dow...
