Growth performance, food efficiency and body composition of pikeperch (Sander lucioperca) were investigated with 1 or 2 g/kg L-carnitine added to the diet. Control diet did not contain L-carnitine. Two hundred pikeperch fingerlings (1.63 g, mean weight) were stocked in each 1 m3 concrete tank and fed equally 6 meals per day for 6 weeks. Higher increment in body weight (5.92 ± 0.37 g), the ...

bioethanol made from lignocelluloses biomass resources, provides unique environmental, economic and strategic benefits, when compared to gasoline as automobile fuel. to be able to substitute gasoline by bioethanol, one should over come many obstacles, including the production of furfural and hydroxyl-methyl furfural, which are produced when cellulosic materials are treated in the presence of ac...

results the results showed that the pcp degradation increased with an increase in zvi dosage from 0.056 to 1.4 g/l, an increase in persulfate concentration from 2.5 to 15.0 mm/l, and an increase in zvi to ps molar ratio from 0.1 to 2.5. the optimal initial ph for pcp removal was 5.0 and the maximum removal efficiency of 70% was achieved within 120 minutes. moreover, the zvi catalyst was reused ...

in order to investigate the effect of plant growth promoting rhizobacteria (pgpr) along with zinc (zn) and manganese (mn), foliar spraying on the morphological parameters of basil (ocimum basilicum l.) an experiment was conducted in factorial based on a randomized complete block design with three replications in 2011. treatments were the pgpr inoculation with azotobacter and azospirillum (azb+a...

an empirical electrical conductivity assessment of nanofluids comprising cuo nanoparticles water-based in different concentrations, particles size and various temperatures of nanofluids has been carried out in this paper. these experimentations have been done in deionized water with nanoparticles sizes such as 89, 95, 100 and 112 nm and concentrations of 0.12 g/l, 0.14 g/l, 0.16 g/l and 0.18 g/...
