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...

generally, developing countries are not able to invest enough on r&d; therefore, they try to get benefit from knowledge spillover, as an external r&d.; this paper tries to investigate the impact of r&d; expenditures and imported intermediate goods, as a proxy for technology imports, on value added of iranian industries. to that end, we use a panel data set of iranian two-digit isic manufacturin...
