BACKGROUND Although the system for producing yellow corn grain is well established in the US, its role among other biofeedstock alternatives to petroleum-based energy sources has to be balanced with its predominant purpose for food and feed as well as economics, land use, and environmental stewardship. We model land usage attributed to corn ethanol production in the US to evaluate the effects o...

this experiment was conducted at the agricultural research farm of isfahan university of technology in 2007-2008 to evaluate the effects of seed treatment and the levels of irrigation regimes on three safflower cultivars. a split plot factorial arrangement was used in a randomized complete block design with three replications. main-plot consisted of three irrigation regimes (60, 105 and 140 mm ...

Shiwa Puhshad Singh, a Rajpoot, aged about 4o, was admitted into the hospital oil the 19th of March, 1870, with the usual symptoms of apoplexy?coma, deep stertorous breathing, pupils firmly contracted, pulse 120, strong full and throbbing, face bloated, indicative of kidney disease?old marks of cupping in the lumbar regions. He had evidently been drinking rather hard the previous day, and the a...

A network model that investigates electrical resistivity and capillary pressure curves of oil/water/rock systems for a full̄ooded cycle (primary drainage, imbibition and secondary drainage) is presented. This model uses a realistic pore geometry in the form of a grain boundary pore (GBP) shape and pore constrictions. The model also incorporates pore-scale displacement mechanisms and pore-scale w...

Life-cycle studies of the currently dominant transport biofuels (bioethanol made from starch or sugar and biodiesel made from vegetable oil) show that solar energy conversion efficiency is relatively poor if compared with solar cells and that such biofuels tend to do worse than conventional fossil transport fuels as to the emission of eutrophying and acidifying substances. Lifecycle studies of ...

mechanisms of tolerance to water deficiency stress for introducing sunflower hybrid was investigated by a two-factor experiment as a split plot design based on rcbd was at the research station in alborz province, hashtgerd region, iran in 2013. irrigation rates (irrigation after 50, 100 and 150 mm cumulative evaporation from class a evaporation pan) were considered in the main plots and sunflow...

introduction obtaining varieties with acceptable yield and tolerant to different arid and semi-arid climate condition of iran is an important goal in canola breeding programs. selection of genotypes base on one or more traits without regarding to correlation between them, could biases the expected results. therefore, identifying of genetic correlation among traits especially in environmental st...
