Transition of ideal, homogeneous, incompressible, magnetohydrodynamic (MHD) turbulence to near-equilibrium from non-equilibrium initial conditions is examined through new long-time numerical simulations on a 1283 periodic grid. Here, we neglect dissipation because are primarily concerned with behavior at the largest scale which has been shown be essentially same for ideal and real (forced dissi...

Long-term paleofire perspectives provide key information on natural and human-derived land cover changes. The last few millennia are crucial to understanding the future of wildfire threats, since increasing global temperatures expected have an impact regions previously assumed not be endangered. In this study we investigate interplay between changing climatic conditions, transformation, fires, ...

BACKGROUND Different studies have implicated the exposure to systemic conditions in the aetiology of cardiovascular diseases like chronic inflammation including chronic periodontitis. AIM The present study has been conducted to examine whether biomarker sTNF-R was elevated in apical periodontitis as sTNF-R is a systemic marker of inflammation and has been identified as risk factors for cardio...

A magnetic resonance microscopy technique was developed to visualize and quantify the three-dimensional structure of snowpack. Because the NMR signal from the ice was very weak, we looked at the air space in the snow that was filled with dodecane doped with iron acetylaetonate. Four types of snow were tested: ice spheres, large rounded poly-crystals, small rounded mono-crystals and depth hoar c...

2014 The synthesis of triaryl-2,4,6 pyrylium tetrafluoroborates substituted by six short (ethyloxy : C2, propyloxy : C3) alcoxy chains has been performed. Classical characterization methods (DSC and optical microscopy) show that these two new compounds present the same columnar phase Dh as that displayed by the other members of the homologous series (C4 to C12). However, these two new compounds...

Redundant disk arrays provide a way for achieving rapid recovery from media failures with a relatively low storage cost for large scale database systems requiring high availability. In this paper we propose a method for using redundant disk arrays to support rapid recovery from system crashes and transaction aborts in addition to their role in providing media failure recovery. A twin page schem...

Previously, a damascene process based on nanoimprint lithography has been proposed (Schmid G M, et al. in J Vac Sci Technol B 24(3) 1283, 2006) to greatly reduce the fabrication steps of metal interconnection in integrated circuit. For such a process to become a viable technique, a mold having two pattern levels with precise alignment between them must be fabricated first. To this end, this wor...
