The non-similar solutions for the unsteady flow of a second grade fluid wereconstructed. The method of perturbation was used for the solution of the governing non-linear equation. The results of Rajagopal et al. (Int. J. Non-Linear Mechanics, 1983) can be obtained as a special case of the presented analysis.

Early number competence, grounded in number-specific and domain-general cognitive abilities, is theorized to lay the foundation for later math achievement. Few longitudinal studies have tested a comprehensive model for early math development. Using structural equation modeling and mediation analyses, the present work examined the influence of kindergarteners' nonverbal number sense and domain-g...

This paper argues that the presence of external control of fluid composition during metamorphism of iron-formation should be indicated by the occurrence of high-grade rocks which either lack the bufering assemblages such as olivine-magnetite-quartz or by the presence of such assemblages in which the silicates show a very restricted range in composition. A review of high-grade iron-formations fr...

qaleh-zari is a fe-oxide cu-ag-au vein type deposit located 180 km south of birjand, in eastern iran. host rocks are mainly tertiary calc-alkaline to k-rich calc-alkaline with transition to shoshonitic andesite and andesitic basalts, but in the central part shale and sandstone of jurassic age. andesitic rocks from the western region of qaleh-zari were dated to 40.5 ± 2 ma. four trends of faults...

The article was first report a case of a 32-year-old female with NPC that is G6PD-deficient. The patient completed induction chemotherapy and concomitant chemoradiotherapy successfully. The patient experienced grade 1 neutropenia , grade 1 diarrhea, and grade 2 acne-like skin reactions during the three cycles of  induction chemotherapy. Grade 1 neutropenia, grade 1 diarrhea, grade 2 oral mucosi...
