babol local lettuce as a landrace in mazandaran, has cultivated for many years. local lettuce is a mixture of different genotypic and phenotypic forms which affects its marketability. it was purified by individual selection method during a three year priod (1998-2000) based on the selection for characteristics such as shape of bush, closed pome high yield, good marketability and resistance to d...

northern regions of khuzestan province are suitable areas for soybean cultivation. hybridization blocks and soybean segregating generations were established in safiabad agricultural research center during 1990-1997 to produce new soybean lines which would have a high seed yield and high adaptability to the region. line l.14 selected from segregating generations of a hybridization between cultiv...

introduction: citrus are one of the important orchard fruit production that after banana is second in production at the world level and every year, chemical fertilizers having most important role in increasing crops productions, but in long application of fertilizers cause soil destructions and polluting underground water. also soils of dry regions are very poor in organic matter level. nowaday...

ABSTRACT We present an estimate of the bulk flow in a volume radii 150−200 h−1 Mpc using minimum variance method with data from CosmicFlows-4 (CF4) catalogue. The addition new CF4 has resulted increase sphere radius 150 relative to CosmicFlows-3 (CF3). This $\sim 0.015~{{\ \rm per\ cent}}$ chance occurring standard cosmological model cosmic microwave background derived parameters. Given that is...

The tensile creep of Al-5Cu-0.8Mg-0.15Zr-0.2Sc(-0.5Ag) was tested at 150–250 °C and 125–350 MPa, the effect Ag on high-temperature Al-Cu-Mg alloys discussed. After addition Ag, performances alloy were significantly improved 150 °C/300 MPa 200 °C/(150 175 MPa). Then, constitutive relational models during built, activation energy calculated to be 136.65 104.06 KJ/mol. Based thermal deformation me...
