TL;DR: In this paper, several studies describe the processing of iron ores via reverse cationic flotation and discuss the predominate role of the pulp mineralogy, as well as the type and molecular structures of the collectors and depressants, on flotation.

TL;DR: There has been considerable recent progress in structural glycobiology with the determination of crystal structures of several important glycosyltransferase members, showing novel folds and variations around a common α/β scaffold.

TL;DR: In this article, an integrated mineralogical and geochemical study was carried out on typical sphalerite (ZnS) samples from the main Ge deposit in western Europe: the vein-type Zn-Ge-Ag-(Pb-Cd) deposit of Noailhac- Saint-Salvy (Tarn, France).

TL;DR: The topics chosen address the most pertinent questions regarding intrapartum management of abnormally invasive placenta with respect to clinically relevant outcomes, including the following: definition of a center of excellence; requirement for antenatal hospitalization; antenatal optimization of hemoglobin; gestational age for delivery; and fertility after conservative management.

TL;DR: An adapted version of the simplified refined instrumental variable method is first proposed to estimate the parameters of the fractional model when all the differentiation orders are assumed known, and an optimization approach based on the use of the developed instrumental variable estimator is presented.
