This work aims to propose an approach estimate the final surface roughness as a function of hardness ratio between coating and debris (Hpin/Hdebris = Hp/Hd) under lubricated conditions employing pin-on-disc configuration. Using this provides better understanding prediction lubrication regime (Stribeck Curve) compared with traditional that uses initial roughness. Our results demonstrate lower in...

Levels of methyl farnesoate in the blood and in vitro rates of methyl farnesoate synthesis by the mandibular organ were investigated to determine whether this compound is related to the differences in morphology and reproductive states of distinct types of male spider crabs described by Homola et al. (1992) in winter populations. Three male types, selected from a summer population, were investi...
