With recent developments in microscopy, such as stimulated emission deletion (STED) microscopy, far-field imaging at resolutions better than the diffraction limit is now a commercially available technique. Here, we analyse how the interplay between shot noise, thermal noise, the saturation intensity of a fluorescent label, and the damage threshold of the sample changes the maximum resolution of...

  This study demonstrates how thermal structures in the interstellar medium can emerge as a result of thermal instability. For a two-dimensional case, the steady state thermal structures was investigeted and it was shown that a large class of solutions exist. For a one –dimensional case the conductivity was found to be negligible. The effects of to cal cooling on the thermal instability were ex...

in internal combustion engines, only about a third of the total fuel input energy is converted into useful work. if the energy rejected into the cooling system and the exhaust gases could be recovered instead and put into useful work, fuel economy would have been substantially improved. the main aim of this research paper was to evaluate the effects of the hybrid nano-catalyst containing cerium...

in the present work, we report the synthesis of binary nano metal oxides such as zinc /copper oxide via novel dry synthetic methods such as thermal decomposition of oxalate precursor. the synthesis route involves facile solid-phase mechanochemical activation of a physical mixture of simple copper/zinc salts and oxalic acid, followed by calcination of the as-ground oxalate precursors at 450◦c. x...

in this work, a thermoplastic polyurethane elastomer (tpue) model based on polytetramethylene glycol, toluene diisocyanate and 1,4-butanediol was selected and synthesized. according to this model two types of polyurethane nanocomposites were prepared by in situ polymerization and melt intercalation procedures. the organo-modified nanoclay was used in nanocomposites samples in 0.4 weight percent...

Introduction: Maintenance of work ability and continuous effort to improve reduced work ability of employees is a major concern for managers. This study aimed to determine the level of work ability index and relation with life style in mechanics of thermal power plant. Method: A total of 60 mechanics from selected thermal power plant were included in this cross sectional study. Health promot...

protein aggregation is a serious problem for both biotechnology and cell biology. diseases such as prion misfolding, alzheimer’s, and other amyloidosis are phenomena for which protein aggregation in our living cells is of considerable relevance. human lysozyme has been shown to form amyloid fibrils in individuals suffering from nonneuropathic systemic amyloidosis, all of which have point mutati...
