The aim of this work is to simulate rare ed gas ow in complex geometries, under ow conditions that range from the hydrodynamic, through the transitional, to the molecular regimes. Existing computational models apply to molecular or viscous ow, but the treatment of the transitional ow is still underdeveloped. To deal with the di cult transitional ow, two models with overlapping ranges of applica...

We have measured the far-field angular distributions of high harmonics (orders 11—41) generated by a 1-p,m, 1-ps laser pulse [(0.3—3)X 10 W/cm ] in low-density Ar, Kr, and Xe targets (~ 1 Torr, 1-mm thick). The far-field harmonic distributions show a narrow central structure surrounded by broad wings that contain approximately 75% of the harmonic energy. Low-density targets and f/70 focusing we...

Extreme Value Theory is the branch of statistics that is used to model extreme events. The topic is of interest to meteorologists because much of the recent literature on climate change has focussed on the possibility that extreme events (very high or low temperatures, high precipitation events, droughts, hurricanes etc.) may be changing in parallel with global warming. As a specific example, t...

inhibitor development is a lifelong challenge for patients with bleeding disorders who received replacement therapy. most commonly, inhibitor formation was observed in hemophilia a patients but patients with rare bleeding disorders (rbd) especially patients with deficiency of factor xiii (fxiii) and factor v (fv) can develop an inhibitor against exogenous factors. several factors considered as ...

Planet Earth's biosphere has evolved over billions of years as a balanced bio-geological system ultimately sustained by sunpower and the large-scale cycling of elements largely run by the global environmental microbiome. Humans have been part of this picture for much of their existence. But the industrial revolution started in the XIX century and the subsequent advances in medicine, chemistry, ...

The physical adsorption of hydrogen sulfide and carbon dioxide gases on the zigzag (5,0) carbon nanotubes doped with nitrogen was investigated through the application of B3LYP/6-31G* at the level of theory on Gaussian 03 software. A variety of stable and high abundance structures of nitrogen doped carbon nanotubes were considered in order to study the interaction between the mentioned gases in ...

Three neutron reactions leading to production of the rare gases Ar41 and Xe135 have been in­ vestigated. Single crystal samples of KF, CaF2 , and BaF2 were irradiated in the Berlin reactor and the target-free absolute activities of the rare gas isotopes measured by a /^-/-coincidence method. The calculated cross sections are K41 (n,p)Ar41: o = ( 2 ,73±0,41) mb; o0= (98,6± 14,8) mb; Ca44(n,a)Ar4...
