Studies of sedimentation stability have shown that for additives containing smaller particles powder components (30…50 nm) it is 1.32 times higher than larger powders (50…300 nm). The analysis the experimental results showed modification Lukoil 10W - 40 engine oil with addition L-60 brass a particle size 30...50 nm contributed to 1.21-fold reduction in friction torque compared 10W–40oil mixed 5...

[1] The energy input to the upper ocean Ekman layer is assessed for the Southern Ocean by examining the rotary cross spectrum between wind stress and surface velocity for frequencies between 0 and 2 cpd. The wind stress is taken from European Center for Medium-Range Weather Forecasts ERA-40 reanalysis, and drifter measurements from 15 m depth are used to represent surface velocities, with an ad...
