OSA Non-sequential optimization technique for a

This overall polishing time can be reduced by performing sequential polishing runs that start with large tools and finish with smaller tools. In this paper we present a variation of this technique that uses a set of different size TIFs, but the optimization is performed globally i.e. simultaneously optimizing the dwell times and tool shapes for the entire set of polishing runs.

Investigation of the Aerosols Produced by a High-speed

Mechanical processes such as grinding are classically thought to form micrometer scale aerosols through abrasion and attrition. High-speed grinding has been used as the basis for testing the hypothesis that ultrafine particles do not form a substantial component of mechanically generated aerosols.

In suspension feeders, the trophi are covered in grinding ridges, while in more actively carnivorous species, they may be shaped like forceps to help bite into prey. In some ectoparasitic rotifers, the mastax is adapted to grip onto the host, although, in others, the foot performs this function instead.

Microbody Enzymes and Carboxylases in Sequential Extracts

Abstract. A seven-step sequential grinding procedure was applied to leaves of Atriplex rosea, Sorghum sudanense, and Spinacia oleracea to study the distribution of carboxylases and microbody enzymes. In the extracts from C 4 species there were 7- to 10-fold reciprocal changes in specific activities of ribulose-1, 5-diphosphate carboxylase and phosphoenolpyruvate carboxylase.
