High-resolution satellite measurements of surface winds and sea-surface temperature (SST) reveal strong coupling between meso-scale ocean eddies and near-surface atmospheric flow over eddy-rich oceanic regions, such as the Kuroshio and Gulf Stream, highlighting the importance of meso-scale oceanic features in forcing the atmospheric planetary boundary layer (PBL). Here, we present high-resoluti...
Atomistic (atom-scale) and coarse-grained (meso-scale) simulations of structure and dynamics of poly-isoprene melts are compared. The local structure and chain packing is mainly determined by the atomistic details of the polymer architecture. The large-time dynamics encountered in NMR experiments can be explained by meso-scale simulations including stiffness. The connecting link between the two...
Multiple length-scale effects are demonstrated in indentation-strength measurements of a range of ceramic materials under inert and reactive conditions. Meso-scale effects associated with flaw disruption by lateral cracking at large indentation loads are shown to increase strengths above the ideal indentation response. Micro-scale effects associated with toughening by microstructural restraints...
Variability at large tomeso-scale in sea surface salinity (SSS) and sea surface temperature (SST) is investigated in the subtropical North Atlantic Ocean during the Subtropical Atlantic Surface Salinity Experiment Strasse/SPURS in August 2012—August 2013. The products of the Soil Moisture and Ocean Salinity (SMOS) mission corrected from large scale systematic errors are tested and used to retri...
Dissipative particle dynamics is a relatively new technique for simulating fluid flow at meso scales that is more computationally efficient but at the same time able to reproduce some of the detail of molecular dynamics simulations. This report gives an introduction to the background of the technique, along with examples of applications in the fields of microfluidics, hydrodynamic behaviour at ...
چکیده: حضور وانادیوم در سیتم های بیولوژیکی و نقش های احتمالی فیزیولوژیکی آن، از جمله افزایش فعالیت انسولین و فعالیت ضد سرطانی، توجه پژوهشگران را برای تحقیق در این زمینه جلب کرده است. کمپلکس های vo-salen و5-br-meso-vo-salen سنتز و فعالیت آنتی اکسیدانی آنها با استفاده از روش احیاء dpph اندازه گیری شد. تأثیر شیب غلظت کمپلکس های فوق بر روی دو رده سلولی hela و mccoy در زمان های 8، 16 و 24 ساعت مورد...
