background : phlebotomus sergenti s.l. is considered the most likely vector of leishmania tropica in iran. although two morphotypes- p. sergenti sergenti (a) and p. sergenti similis (b)-have been formally described, further morphologi­cal and a molecular analysis of mitochondrial cytochrome oxidase i (mtdna-coi) gene revealed inconsistencies and suggests that the variation between the morphotyp...

Now that major milestones have been reached by both the public and private sectors in the quest for the human genome sequence, the focus is shifting to the genetic variability of our species. Lying buried in human genetic variability is the source not only of all genetic disease, but the entire range of normal phenotypic variation, including susceptibilities to pathogens and environmental facto...

In this work, variation of parameter method is applied to study two-dimensional flow of nanofluid in a porous channel through slowly deforming walls with suction or injection. The results of the developed approximate analytical solution using the variation of parameter method is verified with the results of numerical solution using fourth-order Runge-Kutta method coupled with shooing techniques...

We present the first center-to-limb G-band images synthesized from high resolution simulations of solar magneto-convection. Towards the limb the simulations show “hilly” granulation with dark bands on the far side, bright granulation walls and striated faculae, similar to observations. At disk center G-band bright points are flanked by dark lanes. The increased brightness in magnetic elements i...

The number of new dialysis patients has been increasing worldwide, particularly among elderly individuals. However, information on seasonal variation in hemodialysis initiation in recent decades is lacking, and the seasonal distribution of patients' conditions immediately prior to starting dialysis remains unclear. Having this information could help in developing a modifiable approach to improv...
