In this article, the efficiency of time adaptive Rosenbrock and ESDIRK methods is compared for finite volume discretizations for compressible unsteady viscous flows. To make the comparison fair, first an efficient solver for both classes in the JFNK context is identified, where the tolerance TOL that steers time adaptivity is the main input parameter. To specify the tolerances in the sub solver...

Over the past century, solid organ transplantation has been improved both at a surgical and postoperative level. However, despite the improvement in efficiency, safety, and survival, we are still far from obtaining full acceptance of all kinds of allograft in the absence of concomitant treatments. Today, transplanted patients are treated with immunosuppressive drugs (IS) to minimize immunologic...

to study the tolerance of genotypes under terminal drought stress, 20 promising winter and facultative bread wheat genotypes were evaluated at karadj, ardebil, arak and hamedan agricultural research stations during 2001-02 cropping season. the experimental design in all the locations was randomized complete block of three replications. grain yield (yld), harvest index (hi), grain number per spi...

An extended range of novel ruthenium phosphaalkene complexes of the type [Ru{η-N:η-P,C-P(pz)=CH(SiMe2R)}(CO)(PPh3)2] (R = Tol, C6H4CF3-p; pz = pzMe2, pzCF3, pzMe,CF3; R = Me, C6H4CF3-p; pz = pzPh) have been prepared from the respective ruthenaphosphaalkenyls [Ru{P=CH(SiMe2R)}Cl(CO)(PPh3)2] upon treatment with Lipz. Where R = C6H4CF3-p and pz = pzMe2 the complex is characterized by single crysta...

the responses of yield and yield components of 24 advanced bread wheat genotypes to pre- and post-anthesis drought stress conditions were studied at ardabil agricultural re-search station during the 1997-2000 cropping seasons. results showed that genotypes produced significantly lower spikes no./m2, seeds no./spike and grain yield under pre- than in post-anthesis drought stress conditions. howe...

As robot tasks in space nuclear and medical environments be come more widespread the issues of reliability and safety for robots are becoming more critical Attempts to address these is sues have resulted in a recent surge of activity in robot fault tol erance We concentrate on fault tolerance in the robot controller and highlight the importance and potential of multiprocessor con trol architect...

BACKGROUND AND OBJECTIVES The aim of this study was to investigate inflammatory indicators and oxidative status in patients with asbestos exposure with and without mesothelioma and to compare results with data from healthy subjects. METHODS Eighty people with exposure to environmental asbestos and without any disease, 46 mesothelioma patients, and a control group of 50 people without exposure...
