Hydration and thermal shock resistance of MgAlON–MgO ceramics synthesized from spent MgO–C bricks were investigated by hydration experiment water/air quenching method. It was observed that MgAlON does not undergo reaction hydrated MgO only accounts for about 0.2 wt% total amount ceramics. Thermal tests indicated in water show different fracture mechanism at temperature. The retained strength qu...

ObjectiveTo describe the place and cause of death during coronavirus disease 2019 (COVID-19) pandemic to assess its impact on excess mortality.MethodsThis national registry included all adult (aged ?18 years) deaths in England Wales between January 1, 2014, June 30, 2020. Daily COVID-19 were compared against expected daily deaths, estimated with use Farrington surveillance algorithm for histori...

A humidification–dehumidification desalination system powered by low-grade waste heat energy (45 °C–70 °C) was experimentally investigated. The seawater directly utilized as coolant (25 for the dehumidifier preheated latent recovery from water vapor produced humidifier. effect of key performance-contributing factors such mass flow rate and temperature air feed at inlets humidifier were evaluate...

the quenching of quinine fluorescence intensity in the presence of some anions in aqueous solution at ambient temperature has been investigated. the quenching is found to be collisional or dynamical in nature. this study reveals the order of two groups of quencher: nai > nabr > nacl > naf and k2cr2o7 > kmno4 >na2so4 > naclo3. increasing anion size in the both groups leads to an  increase in the...
