ethan kohlberg, the jewish orientalist and specialist on shi‘a, sees the distortion in holy scriptures, including quran, inevitable. from his point of view, some quranic verses confirm this point. his second proof is the history of the quran and the time when its whole text was written down. in his viewpoint,   hadiths which prove that the quran had been written down in abu bakr’s time ore orie...

Transormerless inverters are attractive solution for the grid connected photovoltaic (PV) systems. Unfortunately, it has issues on galvanic isolation between PV systems to the grid. When the galvanic isolation disappears from the PV inverter, leakage currents will flow in a resonant circuit formed by the ground capacitance, the converter, the ac filter and the grid. In order to avoid the leakag...

Stainless steel clad rebar (SCR) was investigated because it may become a cost-effective means of controlling corrosion in concrete under very aggressive environments. Sound SCR (316L cladding) resisted corrosion in saturated Ca(OH)2 solution (SCS) with up to 5 wt% chloride. Cladding breaks on SCR induced significant corrosion of exposed underlying CS in SCS with only 1 wt% chloride. A computer...

A model was developed to determine the influence of steel corrosion products on a-radiolytic corrosion of spent nuclear fuel inside a failed waste container. The model takes into account the a-radiolysis of water, the reaction of radiolytic H2O2 with UO2 both directly and via galvanic coupling with noble metal particles, the reaction with H2 via galvanic coupling, and the Fenton reaction. The d...
