Population reduction and disturbances may alter dispersal, mating patterns and gene flow. Rather than taking the common approach of comparing different populations or sites, here we studied gene flow via wind-mediated effective pollen dispersal on the same plant individuals before and after a fire-induced population drop, in a natural stand of Pinus halepensis. The fire killed 96% of the pine t...

This study numerically investigated heat transfer and fluid flow characteristics in a novel cylindrical heat sink with helical minichannels for the laminar flow of fluid with temperature-dependent properties. A finite volume method was employed to obtain the solution of governing equations. The effects of helical angle, channel aspect ratio, and Reynolds number, which were regarded as main para...

the process of poetry in kuwait has always been progressive during the past centuries as well as the present century. this progression has raised remarkable questions such as is the good economical situation because of the foundation of petrol in this country and so on. the last question is about the time of formation of rticulate poetry in kuwait. the poets of kuwait do not care about the publ...

The necessity for decrease in consumption of conventional fuel, related energy and to promote the use of renewable sources such as biofuels, demands for the effective evaluation of the performance of engines based on laws of thermodynamics. Energy, exergy, entropy generation, mean gas temperature and exhaust gas temperature analysis of CI engine using diesel and karanja methyl ester blends at d...

‎let us consider the set of non-abelian finite simple groups which‎ ‎admit non-trivial irreducible projective representations of degree $le 7$ over‎ ‎an algebraically closed field $f$ of characteristic $pgeq 0$‎. ‎we survey some recent results which‎ ‎lead to the complete list of the groups in this set which are‎ ‎$(2‎, ‎3‎, ‎7)$-generated and of those which are $(2,3)$-generated‎.

Burn injury is associated with immune suppression and the subsequent development of sepsis. Severe burn injury is associated with depressed immune response, including a functional impairment of Th1 lymphocytes and natural killer cells and a decrease in interferon-a production. Dendritic cells (DCs) are potent antigen-presenting cells and play a key role in T cell activation; they are essential ...
