Ecology of Crops in Changing CO2 Concentration

Acclimation of photosynthetic microorganisms to changing ambient CO2 concentration.

P microorganisms can acclimate to a wide range of CO2 concentration, from as low as 0.001% to '10% CO2 (volyvol in the air in equilibrium with their environment). Some can even grow in the presence of 40% CO2 (1). Acclimation to a limiting CO2 level, well below the Km(CO2) of their carboxylating enzyme, Rubisco (ribulose 1,5-bisphosphate carboxylaseyoxygenase), is achieved by substantial physio...

focus on communication in iranian high school language classes: a study of the role of teaching materials in changing the focus onto communication in language classes

چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...
