It is hypothesized that structured sliding-surfaces improve the lubrication condition by forming an oil sump on sliding surface, redistributing oil, and trapping wear debris. For these reasons, have been used as a friction reduction method for long time. In this work, effects of microstructure laid cylinder liner internal combustion engine twin-land control ring (TLOCR) piston skirt were invest...

The greenhouse experiment was conducted to evaluate the effect of black polyethylene (PE) plastic mulch on yield and some quality parameters tomato. In study, PE material laid raised beds bare soil (not mulched) used as control. Mulch did not affect plant height, fruit shape index, chroma hue angle, firmness, soluble solids content, titratable acidity. Black had a positive influence yield. Sign...
