In the present study the modified Ludzack-Ettinger predenitrification process was employed for the biological treatment of oil refinery wastewater. For this purpose an anoxic tank coupled to an oxic MBR operated at SRT and HRT of 60 days and 24hr , respectively was used. The findings of the present study showed that using a recylcle ratio (R) equal to both 2 and 4, COD and phenol removal effici...
fruit yield efficiency and some vegetative characteristics of commercial and spur type apple. cultivars was evaluated in dr. nakhjavani field station, orumieh, iran, in 2008 and 2009 growing seasons. apple cultivars included: red spur, red chief, golden spur, yellow spur, fujii, red delicious, cooper spur, red cooper spur, jonathan, golden delicious, oregon spur, jonagold. the experimental desi...
in order to evaluate radiation capture and use efficiency and productivity in sole and intercropping of three crops, rapeseed (brassica napus l.), bean (phaseolus vulgaris l.) and corn (zea mays l.), an experiment was conducted in mashhad region during the growing season of 2007-2008. in this study six treatments including three sole cropping of the crops (rapeseed sown in 22 september 2007, co...
In this paper, we describe a new application domain for intelligent autonomous systems – Intelligent Buildings (IB). In doing so we present a novel approach to the implementation of IB agents based on a hierarchical fuzzy genetic multi embedded-agent architecture comprising a low-level behaviour based reactive layer whose outputs are co-ordinated in a fuzzy way according to deliberative plans. ...
A new low-leakage-inductance low-resistance design approach to low-voltage high-power isolated boost converters is presented. Very low levels of parasitic circuit inductances are achieved by optimizing transformer design and circuit lay-out. Primary side voltage clamp circuits can be eliminated by the use of power MOSFETs fully rated for repetitive avalanche. Voltage rating of primary switches ...
