The study of teachers’ pedagogical knowledge base (PKB) to discover how teachers think and work is attracting increasing attention in ELT. Against this background, the present study aimed at probing the likely variations in EFL teachers’ pedagogical knowledge base as a function of their teaching license status. To this aim, six teachers (two standard-licensed, two alternatively-licensed, and tw...

this study was conducted to evaluate the responses of two greenhouse tomato cultivars to nutrient solutions' electrical conductivity (ec). two cluster type greenhouse tomato cultivars (razan and ergon) were grown in perlite in a glasshouse hydroponic system. the grown plants were daily fed with either constant ec nutrient solutions (ecs 2, 3 ds m-1) or nutrient solutions of alternatively c...

Alternative splicing is a well-recognized mechanism of accelerated genome evolution. We have studied single-nucleotide polymorphisms and human-chimpanzee divergence in the exons of 6672 alternatively spliced human genes, with the aim of understanding the forces driving the evolution of alternatively spliced sequences. Here, we show that alternatively spliced exons and exon fragments (alternativ...
