a lab-scale sbr equipped with a flat sheet membrane in submerged configuration that is named msbr was used for the treatment of composting leachate. it was fed by biologically treated leachate with overall 70-1360 mg/l chemical oxygen demand (cod). the values of ph, electrical conductivity (ec), and dissolved oxygen (do) were monitored routinely. however, analysis of total cod, soluble cod (sco...

abstract an investigation was undertaken to ascertain the influence of hydro-alcoholic solutions on plant growth as well as quality attributes of strawberry fruits. the mother plants of strawberry (fragaria ananasa cv. gaviota) were subjected to various aqueous solutions of ethanol (15, 30%), methanol (15, 30%) and the mixture of ethanol + methanol (15 or 30%) plus the control (water only) as f...

The effects of edible coatings based on gum arabic (GA) (0.5–1.5%), maize starch (MS) lemongrass oil (LO) (2–4%), and glycerol (GC) (0.5–1%) developed using response surface methodology (RSM) “Wonderful” pomegranate fruit were studied. After 42 days storage (5 ± 1 °C, 95 2% RH) 5 at ambient temperature (20 0.2 °C 60 10% RH), whole evaluated for weight loss (%) juice (PJ) total soluble solids (°...

An analytical model for the linear Richtmyer-Meshkov instability in solids under conditions of high-energy density is presented, in order to describe the evolution of small perturbations at the solid-vacuum interface. The model shows that plasticity determines the maximum perturbation amplitude and provides simple scaling laws for it as well as for the time when it is reached. After the maximum...

such aabiotic stresses like water stress are some of the most important threats to the production of agricultural crops. it is almost very rare to find a place with no stress where plants can reach their potential yield. a water stress of 17 percent decrease yield, due to its effect upon fruit setting is notable. therefore, a study was conducted in bushehr agricultural research center (located ...

light intensity is considered a limiting factor in greenhouse rose production. the main aim of this experiment was to evaluate the effect of shading treatments (0, 25, 50, and 65% shading) on quality and chlorophyll content of cut rose (rosa hybrida cv. avalanche), under greenhouse conditions. the experiment was planned in randomized completely block design with four replications. all shoots we...

The paper describes that the first signs of beetle movement after night rest in month May occur at 8 am an air temperature about 20 0 C. Increasing to 22-29 C tends increase their mobility. By 11 a.m., when reached 34 C, almost all beetles went into shade, lower part plants, where they remained immobile until 4 p.m. After 17 h. dropped 330С, by 20:00 200С. this time, only a small active. In sum...
