Bonding agents (BA) are key compounding ingredients for the correct formulation of composite solid rocket propellants (CSRP). In particular, addition BA is essential to achieve suitable mechanical properties CSRP in terms adequate tensile strength and elongation at break. It shown that polarity each conventional as well new potential can be measured through Reichardt’s ET(30) scale. Using this ...

The small commercial stores opening in housing structures Seoul have been soaring since the beginning of this century. While commercialization generally increases urban vitality and achieves land use mix, cafés restaurants low-rise residential areas may attract numerous passenger populations, with increased noise crimes, area. is so fast prevalent that neither researchers nor policymakers can r...

We introduce a general and relatively straightforward protocol aimed at determining the absolute photoinduced radical generation efficiency via NMR monitoring. This approach relies on use of scavenger probe that combines nitroxide moiety specifically reacts with radicals trifluoromethyl group used as 19F signaling unit. Using an LED source, whose fluence is precisely determined by chemical acti...

PURPOSE Soluble ST2 (sST2) is an emerging prognostic biomarker in patients with cardiovascular disease (CVD). A recent study showed that sST2 predicted incident hypertension. High sensitive C-reactive protein (hsCRP) has been a widely-used biomarker for risk-stratifying in CVD. We compared the abilities of sST2 and hsCRP to predict high risk coronary artery calcium score (CACS). MATERIALS AND...

The phenomenon of knock is an abnormal combustion occurring in spark-ignition (SI) engines and forms a barrier that prevents increase thermal efficiency while simultaneously reducing CO2 emissions. Since knocking highly stochastic, cyclic analysis in-cylinder pressure necessary. In this study we propose approach for efficient robust detection identification three different internal engines. pro...

This study focuses on the effects of elevated building substructure porosity on the accumulation of drifting snow. We conducted wind tunnel experiments of the snowdrift accumulation and numerical simulations to determine the flow field around a prototypical elevated building (based on the Martin A. Pomerantz Observatory or MAPO) with varying substructure porosity. We found that the total drift ...
