Seaweed extract can improve the physicochemical properties of the soil and has a favorable effect on the plant growth and development due to having high nutrient content, high water holding capacity, plant growth regulators and beneficial microorganisms. The aim of this experiment was to investigate the effect of Ascophyllum nodosum extract, a brown alga, on the morphophysiological characterist...
the effect of the presence of perforations on he stresses of a plate is a problem which is of great interest in structural design and in the mathemattical theory of elasticity. among the many hole patterns that are likely to require consideration is the ring of equally spaced circular holes. the present worke investigates stress & strain analysis of a thin isotropic circular plate containing a ...
shortage of water in arid and semiarid regions of the world can reduce growth and production of medicinal and aromatic plants, especially mentha species. in order to evaluate response of mint species to water deficit stress, an experiment was carried out using a completely factorial-randomized design with five replications at college of agriculturae, ferdowsi university of mashhad, iran. the fa...
Tall wheatgrass (Elymus elongatum Host) is a drought-tolerant, cool-season forage grass native to Iran. A proteomic approach has been applied to identify mechanisms of drought responsiveness and tolerance in plants undergoing vegetative stage drought stress and then recovery after rewatering. Uniformed clones were reproduced from a parent plant collected from Brojen (central region of Iran). Cl...
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 this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
current global water shortage and water pollution problem are some of the crucial issues in theworld, especially in the arid zones. the wastewater reuse was investigated the efficiency of fecal coliform(fc) removal using the intermittent media infiltration (imi) with varying soil content and natural porousmedia (sand, zeolite, vermicompost and charcoal), and its prediction was introduced by app...

The effects of Drought and salinity stress on the growth and chemical compositions pennyroyal(Mentha pulegium L.) plant were investigated. This experiment was carried out in a factorial-randomized design with four replications in controlled conditions and plantlets were subject to four soil moisture regimes (40, 60, 80 and 100 of field capacity (FC)) and five salt treatments with 0, 25...
Efficient nitrogen (N) nutrition has the potential to alleviate drought stress in crops by maintaining metabolic activities even at low tissue water potential. This study was aimed to understand the potential of N to minimize the effects of drought stress applied/occur during tillering (Feekes stage 2) and jointing (Feekes stage 6) growth stages of wheat by observing the regulations and limitat...
