some specific and non-specific immune variables of rainbow trout were assessed following vaccination of fish with formalin killed cells (fkc) and fkc containing extra cellular products (ecp) of s. iniae. rainbow trout weighing 80-100 g were vaccinated by intraperitoneal (i.p), dip and oral routes using fkc and fkc plus ecp with or without fround adjuvant (fa) at 16-17°c.antibody titration, lyso...

drought and salinity are the most important environmental stresses that are causing adverse effects on natural ecosystems. there are species among iranian natural germplasm that are resistant to environmental harsh conditions. restoring of degraded ecosystems, promoting of biodiversity and increasing of species richness will provide by identifying of these species. almond species with broad eco...

in order to evaluate effect of azotobacter chroococcum strains on yield, yield components and qualitative indices of winter rapeseed (brassica napus l.), an experiment was conducted during 2009-2010 growing season at research institute of rice in rasht. the experimental design was completely randomized block, with three replications. investigated treatments were including control (without seed ...

in order to study the effects of four concentrations (check, 5, 10 and 15%) of hull extracts on growth of 10 iranian rice cultivars, two experiments were conducted in completely randomized block design with factorial arrangement and three replications at two sites, laboratory and greenhouse. laboratory study showed that same rice hull extracts had stimulat effects and the others had inhibitory ...

in order to comparison the foliar application of biological, biostimulator and chemical fertilizers on growth characteristics and yield of saffron, a factorial experiment was conducted in a completely randomized block design with four replication in 3- year field of saffron in dargaz, khorasan razavi province from 2010 to 2011. the first factor had 5 levels included biostimulator fertilizer bio...

improving the processing and the recycled paper properties is one of permanent concern of papermaking. in this research, the effect of nanochitosan addition on the process and product quality made of writing and printing recycled fiber was investigated. being nano size and so its capability in access to the space between pulp suspension components and also its probable ability to make electrost...

in order to investigate the effects of boron, zinc and sulfur on yield and fatty acid composition of rapeseed(hyola 401 cultivar), an experiment was conducted in rasht province in 2011. a field experiment withcompletely randomized block design was performed with eight treatments in three replications.maximum grain yield (4157.6 kg ha-1) and grain oil (1770.2 kg ha-1) was obtained from s+b+zntre...

drying, is one of the important postharvest processes of medicinal plants with an important role played in quality and quantity of the drugs. in this research, in order to study the effect of growing conditions and different drying methods on drying time, essential oil content, color characteristics and microbial load of dracocephalum moldavica, a factorial experiment in randomized complete blo...

the moe and mor are controlled by production variables of particleboard process. now, the basic question is which of the particleboard variables is effective on bending strength property? 13 variables of internal scientific resources were measured with 100 repeats. the study steps include the following; liner regression or stepwise, genetic algorithm, and artificial neural network. the number o...
