TG, FT-IR and NMR characterization of n-C16H34 contaminated alumina and silica after mechanochemical treatment [PDF]
, 2008 This paper deals with the application of mechanochemistry to model systems composed of alumina or silica artificially contaminated with n-C16H34. The mechanochemical treatment was carried out by means of a ring mill for times ranging from 10 to 40 h ...

Time-sequential extraction of motion layers [PDF]
2008 15th IEEE International Conference on Image Processing, 2008 A new time-sequential approach for motion layer extraction is presented. We assume that the scene can be described by a set of layers associated to affine motion models. In one or more key frames, the segmentation is obtained using a semi-automatic method.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
