asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...

In order to study the effects of superabsorbent polymers and drought stress on some morphological characteristics of Rosmarinus officinalis, a pot experiment was conducted as factorial, based on completely randomized design with four replications, in which factors included four levels of drought stress (irrigation up to 100, 75, 50 and 25 percent of field capacity (FC) level, respectively) and ...

  Lettuce is one of the major leafy vegetables that is consumed as fresh and salads crops. Although, today, the tendency is to grow lettuce as hydroponic crop, there is not an optimal nutrient solution and growers use different nutrient solutions for growing lettuce.

Abstract Strong, tall and healthy stems, as well as green background by means of leaves, are very important characters in marketing of cut flowers including Lily (Lilium). Also, in order to reuse the bulbs for next crop production, they should have enough stored materials and perimeter. This investigation was conducted to evaluate the effects of different media on some vegetative characters of...

Salinity and waterlogging are two important abiotic stresses to plants growth and yield in the world. These two stresses can occur simultaneously and have additive effects on plants, including corn, growth. In a greenhouse experiment, the effects of NaCl salinity and waterlogging and their interactive effect on the growth characteristics of forage corn (Zea mays cv. single cross 704) were studi...

In order to improve the quantitative and qualitative traits of lisianthus (Eustoma grandiflorum “Mariachi Blue”) a factorial experiment ws performed as completely randomized design at three levels of vermicompost (0, 5 and 10% v/v) and humic acid (0, 2 and 4 kg/m3) with three replications, under the greenhouse conditions. Evaluated traits were number of Leaves, buds and branches, pe...
