like other developing countries, iranian cities are growing and expanding physically at a high speed. for about five decades, the only policy of the urban development plans in the field of urban growth management has been definition of the urban growth boundary (u.g.b.) which is still used without any major modifications.despite the slight evidences indicating the ineffectiveness of the current...

this experiment was conducted to evaluate the efficacy of different levels of echinacea (echinacea purpurea) methanol extract on the growth performances (final weight (fw), daily growth ratio (dgr), feed conversion rate (fcr), voluntary feed intake (vfi) and protein efficiency ratio (per) and some of hematological parameters (hemoglobin (hb), hematocrit (hct), red blood cell (rbc) and white blo...

The present study evaluated the effect of Lactobacillus plantarum as a probiotic on the growth performance and haematological parameters of juvenile rainbow trout (O. mykiss) weighing 29.6±1.8 g immunized with streptococcus/lactococcus vaccine. Fish were randomly allocated into 4 equal groups consisting of fish fed with the probiotic  supplemented in diet (group P), fish immunized with streptoc...

The present study evaluated the effect of Lactobacillus plantarum as a probiotic on the growth performance and haematological parameters of juvenile rainbow trout (Oncorhynchus mykiss) weighing 29.6±1.8 g immunized with streptococcus/lactococcus bivalent vaccine for 60 days at 16±1.5ºC. Fish were randomly allocated to 4 equal groups: probiotic (g kg-1 feed equal to 108 cells g-1) supplemented d...

spawn quality plays an important role in successful production of medicinal mushrooms. in this study, firstly, to determine the optimum temperature for mycelia growth of g. lucidum, four basal media, including seeds of wheat, barley, millet and abies sp. wood chip were studied separately at 25±1˚c and 29±1˚c. in the second section, in order to achieve suitable the mycelia growth, barley, wheat ...
