in this work, we consider each normal alkane as a hypothetical mixtureof methyland methylene groups, in which the interaction potential of each pair is assumed to be the average effective pair potential. then, the lir equation of state (eos) is extended for such a hypothetical mixture. also, three basic compounds, namely, propane, n-butane and cyclohexane, are used to obtain the contribution of...

It is shown that the renormalization group method does not necessarily eliminate all secular terms in perturbation series to partial differential equations and a functional subspace of renormalizable secular solutions corresponds to a choice of scales of independent variables in the reductive perturbation method. Recently a novel method based on the perturbative renormalization group theory has...

Vocabulary learning is considered to be the most comprehensive and the most difficult part of language learning for all the students especially for ESP students. These students complain that vocabulary items are too many and are easily forgotten after they are learned. Mnemonic devices, a group of mental strategies, are developed to facilitate vocabulary learning and retention for such students...
