Based on a brief review of articles discussing how to predict JIFs and taking data differences between the Web of Science （WoS） and the JCR into account, we make our own predictions. Using data by cited-reference searching for Thomson Scientific＇s WoS, we predict 2007 impact factors （1Fs） for several journals, such as Nature, Science, Learned Publishing and some Library and Information Sciences journals. Based on our colleagues＇ experiences we expect our predictions to be lower bounds for the official journal impact factors. We explain why it is useful to derive one＇s own journal impact factor.展开更多

However it does not obtain enough attention at present. The application and problems of English newspaper reading in English Teaching in Higher Vocational Colleges are discussed in terms of English teaching material selection＇s appropriateness, teaching 1 diversity and the major problems. The summary of experience lesson is made and teaching suggestions are put forward, which makes a constructive effect on English newspaper reading development in English Teaching in Higher Vocational Colleges.展开更多

The method is based on the regularities of Rayleigh wave propagation in solids with initial （residual） stresses. A description of the above mentioned method and examples of stress determination are presented. Examples are considered as applied to the residual stresses arising at electric welding and the operating stresses arising at loading.展开更多
