RANS Study on the Impact of Equivalence Ratio on Natural Gas/Diesel-Fueled Combustion in RCCI Engine [PDF]
The primary reason in favor of Reactivity Controlled Compression Ignition (RCCI) is that combustion occurs at low temperature, leading to low thermal NOx. Using the RCCI approach is highly demanded due to stringent emission laws.

Revisiting the Reynolds-averaged Navier–Stokes equations
This study revisits the Reynolds-averaged Navier–Stokes (RANS) equations and finds that the existing literature is erroneous regarding the primary unknowns and the number of independent unknowns in the RANS. The literature claims that the Reynolds stress

S-adenosyl-L-methionine: (S)-scoulerine 9-O-methyltransferase, a highly stereo- and regio-specific enzyme in tetrahydroprotoberberine biosynthesis [PDF]
Suspension cultures of Berberis species are useful sources for the detection and isolation of a new enzyme which transfers the methyl group from S-adenosyl-L-methionine specifically to the 9-position of the (S)-enantiomer of scoulerine, producing (S ...
