in order to evaluate the effect of intercropping with replacement and additive series for hemp (cannabis sativa l.) and sesame (sesamum indicum l.), a field experiment was conducted during growing season 2006-07 at the agricultural research station of ferdowsi university of mashhad, iran. a randomized complete block design with three replications was used. treatments included different combinat...
in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
in order to study the impact of replacement and additive intercropping series on yield and yield components of bean and ajowan as a medicinal plant, an experiment was conducted based on a randomized complete block design with three replications at the agricultural research station, shirvan college of agriculture and natural resources during growing season of 2012-2013. nine replacement and addi...
Objective(s): Anticonvulsant activity of phthalimide was discovered in 2000 by molecular hybridization of thalidomide and ameltolide. In our previous research we have reported some new 4-substituted derivatives of phthalimide with good activity against the tonic and clonic seizures Material and Methods: A series of novel 4-flurophthalimides that designed using bioisosteric replacement were synt...

Age-replacement is one of the most commonly usedmaintenance policies based on preventive action to prevent system failure. Inmany age-replacement settings, it assumed that maintenance time can beignored since short compared with operation time. However, maintenance,especially corrective maintenance, may take a non-negligible amount dueto various factors such as ordering replacement parts, equip...
introduction: increasing costs of herbicide inputs in intensive crop production systems and the incidence of herbicide resistance in weeds have renewed interest in exploiting crop competitiveness to reduced herbicide use. two factors contribute to crop competitiveness against weeds: ability to withstand competition (awc), or the ability to maintain high yields in the presence of weeds, and weed...
