Decomposition of Bayer process organics: Phenolates, polyalcohols, and additional carboxylates [PDF]
, 2011 The degradation of nineteen low-molecular-weight phenolates, polyalcohols and selected aliphatic and aromatic carboxylates of relevance to the Bayer process has been studied in 6 mol kg-1 NaOH(aq) at 90 °C for up to 36 days, and (for some species) at 180

Mineralogical and geochemical characteristics of two bauxitic profiles, Fria, Guinea Republic [PDF]
, 1996 Bauxite deposits of the Fria district, Guinea, have been exploited since 1960. These lateritic bauxites, located on the upper parts of plateaus, result from weathering of paleozoic schists.

Bayesian demosaicing using Gaussian scale mixture priors with local adaptivity in the dual tree complex wavelet packet transform domain [PDF]
, 2013 In digital cameras and mobile phones, there is an ongoing trend to increase the image resolution, decrease the sensor size and to use lower exposure times. Because smaller sensors inherently lead to more noise and a worse spatial resolution, digital post-
