The Allee Effect: Its History and Future Importance

The role of mutually beneficial interactions (++, cooperation) is a rapidly growing research field in population dynamics, microevolution, and conservation biology. Such positive influences cause destabilizing pressures in population dynamics (anti-regulating factors), and can generate Allee effects. Not only can large demes benefit from such cooperation, but the loss of cooperation in small de...

the effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test

in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...

The effect of aspirin on the interaction of histone 05 and 05-DNA

The linker histones (H1 or H5) which play a key role in the folding of chromatin, are general repressors of gene expression. Nuclei of the mature chicken erythrocytes (and in some mammalian cells) contain both of them. Although the interaction of H5 with DNA is stronger than that of H1, it does not prevent the transcription of some erythroid-specific genes. It has been shown that some modificat...
