Left-handed female subjects, categorized as using an inverted (LI) (n=7) or non-inverted (LN) (n=7) writing posture, were compared on performance of a motor task. Task parameters were manipulated to create four conditions varying in demand for sequential processing. Based on previously observed group differences in the direction and extent of hemispheric lateralization, non-inverted writers wer...

communicative moves and lexical cohesion patterns (lcps), as mounting evidence shows, are two important indicators in writing and publishing the ras. however, the interaction between these two crucial elements and the contribution of this interaction to the failure or success of the ras have not been given due attention to date. having this in mind and based on a sound theoretical framework, at...

background: the status of measles elimination is best summarized by evaluation of the effective reproduction number r; maintaining r < 1 is necessary and sufficient to achieve elimination. in the present article, we estimated reproduction number  for the measles data reported for the fars province of iran in 2001–03.   methods: we estimated by using sizes and durations of chains of measles tran...

the search for new stationary phases has been one of the predominant concerns in high performance liquid chromatography (hplc) in order to achieve better resolutions, longer column lives, and reduce the time of analysis. a chromatographic packing for separation of underivatized amino acids (aas) were prepared by dynamically coating 2-amino tetraphenyl prophyrin (atpp) on a c-18 reversed-phase p...

We simulate freely jointed chains to investigate how knotting affects the overall shapes of freely fluctuating circular polymeric chains. To characterize the shapes of knotted polygons, we construct enveloping ellipsoids that minimize volume while containing the entire polygon. The lengths of the three principal axes of the enveloping ellipsoids are used to define universal size and shape descr...
