Studies have shown that during the process of Interlanguage development, language learners cannot avoid making grammatical errors in either spoken or written form. Although it is considered as a normal phase, can lower students' confidence to be active EFL class. Accordingly, they need teachers’ appropriate corrective feedback (CF) produce effective communication target language. Thus, consider...

In April of 1992, a group of parallel computing vendors, computer science researchers, and application scientists met at a one-day workshop and agreed to cooperate on the development of a community standard for the message-passing model of parallel computing. The MPI Forum that eventually emerged from that workshop became a model of how a broad community could work together to improve an import...

Modern diuretic therapy evolved from 2 seemingly unrelated events in the 1930s: the development of sulfanilamide, the first truly effective antibacterial agent, and the description of the enzyme carbonic anhydrase. Sulfanilamide was observed to increase sodium (Na )/potassium and water excretion by inhibition of carbonic anhydrase activity. Recognition of this action proved the impetus for synt...

It has been conjectured that self-replicating systems will enable complex macroscale objects to be made in a reasonable time using nanoscale assembly processes [1]. Self-replicating systems might also be used within reconfigurable structures on any scale, such as micro-circuits. An abstract model of a programmable constructor in a kinematic simulation environment is presented. This programmable...
