the main purpose of this study is to perform numerical simulation of nanofluids as the coolant in vver-440 fuel rod bundle. the fuel rod bundle contains 60 fuel rods with length of 960 mm and 4 spacer grids. in vver-440 fuel rod bundle the coolant fluid (water) is in high pressure and temperature condition. in the present thermo-hydraulic simulation, water-al2o3 nanofluids containing various vo...

In the loanword phonology of Japanese, voiced obstruent geminates ([bb, dd, gg]) have been claimed to devoice when they co-occur with another voiced obstruent within the same morpheme (e.g. /beddo/ → [betto] ‘bed’). This devoicing pattern has contributed much to address a number of theoretical issues in the recent phonological literature. However, the relevant data have been primarily based on ...

Morphological, biochemical and molecular characteristics were studied to identify dominant lactic acid bacteria (LAB), isolated from traditional yoghurts produced by tribes of Iran. From 60 yoghurt samples, a total of 137 LAB isolates were determined, in which 66 and 71 were identified as lactic acid cocci and bacilli, respectively. Biochemical tests showed the occurrence of 9.76% mesophilic ho...
