abstract this study aimed at investigating the effect of bilingual teaching of cognate words (persian-english) on iranian upper intermediate efl learners’ knowledge of lexical development. for this purpose,100 subjects participated in this study out of which 40 learners were selected for this study and they were assigned into two groups, control and experimental. cross-language cognates (wor...
Human sperm cryopreservation for assisted reproduction is compromised by ROS-induced sperm cryodamage. Our previous model study in which mouse sperm were treated with H₂O₂ to simulate sperm DNA-damage caused by cryopreservation-induced ROS have discovered that mouse embryos fertilized with treated sperm showed a delay in cleavage that might be associated with cell cycle arrest. The DNA-damage c...
The use of an endemic plant as rootstock has many merits but its application for cucurbits production not been extensively investigated. present study determined the growth responses grafted cucumber using two rootstocks from Cucurbita pepo L. fertilized with different ratios nitrate (NO3-): ammonium (NH4+) fertilizer. A greenhouse was carried out (C. sativus ‘Dominos’) on accessions collected ...
Because of their worldwide distribution and profuse pollen production, grasses represent a major aeroallergen source for 40% of allergic patients. In Southern Africa there are 94 genera (10% of the world total) and 967 species of grass. Of these, 847 species are indigenous, and 115 are naturalised. Southern Africa comprises both subtropical and temperate regions, where grassland and savannah bi...
Type I allergy is a major health problem in industrialized countries where up to 15% of the population suffer from allergic symptoms (rhinitis, conjunctivitis, and asthma).
