Bioreactors which energy in a liquid and gas form is imported are universal in regard to management and establishment a definite mass exchange as mixing. In the mechanical mixing of the environment, the gas reaches its highest dispersion in the liquid as a result of the turbulence received. Having enough gas content, this may cause a huge relative surface of the phases contact; thus allowing th...

in order to evaluate the effect of different planting patterns and different varieties of corn on quantity management in 2015 as a split-plot in a randomized complete block with 3 replications. the test pattern as the main factor in two levels in the atmosphere and the stack corn hybrids in four sub-levels maxima, asv3, magi 704 and 400 were hybrids. the effect of planting pattern, the maximum ...

Development of agriculture depends on optimal land allocation. The development towards optimal utilization of land under cultivation and thereby increasing the production of crops and profit with less fertilizer consumption have to be taken into consideration in agriculture planning. In this paper different agriculture strategies are developed and accordingly, single objective optimization mode...

The present study was conducted at Khorassan Agricultural Research Center in order to determine the amount of seeds in nursery and the best transplanting date for black zira (Bunium persicum) bulbs from nursery to field and to find out the best cultivation pattern in the field. Treatments consisted of six seed rates (20, 60, 100, 180 and 220 kg/ha) which were sown on November 1996. Results reve...

BACKGROUND RNA interference (RNAi) is a specific and effective approach for inhibiting viral replication by introducing double-stranded (ds)RNA targeting the viral gene. In this study, we employed a combinatorial approach to interfere multiple gene functions of white spot syndrome virus (WSSV), the most lethal shrimp virus, using a single-batch of dsRNA, so-called "multi-WSSV dsRNA." A co-culti...

The principal objective of this study was to acquire basic data regarding the mycelial growth characteristics for the artificial cultivation of Coprinus comatus. 12 URP primers were employed to evaluate the genetic relationships of C. comatus, and the results were divided into three groups. Among six kinds of mushroom media, MYP medium was selected as the most favorable culture medium for C. co...
