Production of haploid plants is an efficiant method in plant breeding programs, genetics and cytogenetics studies. Effects of cultivar, medium and plant growth regulators were investigated on anther culture of strawberry. This study was carried out using two commercial cultivars of satrawberry (Selva and Paros), three medium (MS, H1 and N6) and different concentrations of IAA and BAP as factori...
abstract the primary purpose of this study was to explore the actual practices and cognitions of two groups of iranian eap teachers, i.e. language teachers and content teachers, with respect to teaching reading-comprehension and vocabulary. to this end, tehran university of medical sciences which authorizes both groups of teachers to teach eap courses was selected as the context of the study s...
laboratory-scale experiments were conducted to evaluate the joint action toxicity and biochemicaleffects of sublethal concentrations of forcados light crude oil (flco) and three dispersants against clariasgariepinus over a period of 28 days. the derived 96hrlc50 values revealed that the dispersant, ds/tt/066(0.03ml/l) was the most toxic, followed by dispersant, oc/tt/osi (0.19ml/l), flco (5.06m...
abstractthe purpose of this study was to investigate the controllable operating parameters influence, including ph, solid content, collector, co-collector, and depressant dose, and conditioning time, on apatite flotation kinetics. four first order flotation kinetic models are tested on batch flotation time-recovery profiles. the results of batch flotation tests and the fitting of first-order ki...
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
the present study used a constant level of citric acid and polyvinyl alcohol and different amounts of nanocrystalline cellulose (cnc) and tio2 nanoparticles to improve the properties of starch film. the effect of different amounts of glycerol was also examined. the results of differential scanning colorimetry demonstrated that the addition of cnc increased the melting and glass transition tempe...
