the present study aims to investigate language learners’ cognitive processes in on-line esp courses. three modes of inquiry are used: think-aloud protocol analysis, screen capture analysis, and correlation analysis. the theoretical foundations for the evaluation of the cognitive aspect of ferdowsi univeristy of mashhad e-learning system are drawn from cognitive load theory, cognitive apprentice...

An essential requirement for providing secure services in wireless sensor networks is the ability to establish pairwise keys among sensors. Due to resource constraints on the sensors, the key establishment scheme should not create significant overhead. To date, several key establishment schemes have been proposed. Some of these have appropriate connectivity and resistance against key exposure, ...

background among all pediatric cancers acute lymphoblastic leukemia (all) is highly prevalent, butthe overall cost of all management is not well-known, there is a need to assess the berlin-frankfurt-munster (bfm) protocol commonly used in all management in iran. so, the aim of this study was to estimate direct and indirect costs of all treatment among children based on the all-bfm protocol from...

Security protocol participants are software and/or hardware agents that are—as with any system—potentially vulnerable to failure. Protocol analysis should extend not just to an analysis of the protocol specification, but also to its implementation and configuration in its target environment. However, an in-depth formal analysis that considers the behavior and interaction of all components in th...

introduction: although hippocampus is the most famous brain area involved in temporal lobe epilepsy, hippocampal kindling (hk) develops very slowly. hence, rapid kindling is usually preferred to the traditional kindling and it is widely used. in this article we aimed at finding the optimal stimulus pattern, which yields the fastest hk rate. methods: stimulus patterns with different duration (2,...

Genomic DNA extraction with a high quantity and quality is a basic requirement in molecular biology. The DNA obtained was free of any contamination proteins, polysaccharide, polyphenols and colored pigments. These compounds would interfere with the genomic isolation procedures and downstream reactions such as restriction enzyme analysis and gene amplification. The isolated genomic DNA was fo...
