Digital cameras are now commonly included in several digital devices such as mobile phones. They are present everywhere and have become the principal image capturing tool. Inherent to light and semiconductors properties, sensor noise [10] continues to be an important factor of image quality [12], especially in low light conditions. Removing the noise with mathematical solutions appears thus una...

The Bayer Process (for alumina) as we know it today involves two steps: • The pressure leaching of bauxite with NaOH solution to obtain sodium aluminate solution. • The precipitation of pure aluminum hydroxide from this solution by seeding with fine crystals of Al(OH)3 . The leaching step was invented five years after the precipitation step (Table 1), and the precipitation step was an improveme...

in an attempt to determine the chemical losses of three common molluscicides, i.e. cuso4, napcp and bayer –73, in stagnant water, a solution of each of this molluscicide was applied to one or more b.truncatus habitats and outdoor aquariums. the concentration of each molluscicide in these water bodies was determined immediately after application and at fixed time intervals thereafter. the concen...

The utility of Compressed Sensing (CS) for demosaicing of digital images have been explored by few recent efforts [1][2][3]. Most recently, a Compressive Demosaicing [3] framework, based on employing a random panchromatic Color Filter Array (CFA) at the sensing stage, has provided compelling CS-based demosaicing results by visually outperforming other leading techniques. Meanwhile, it is well k...

Aluminum metal is produced by the electrolytic reduction of aluminum oxide (Al2O3), mainly extracted from bauxite ore digested in a hot caustic soda solution. This solution is supersaturated with respect to sodium aluminate and silicate, which react together to form sodalite (3[Na2O⋅Al2O3⋅2SiO2⋅2H2O]⋅Na2CO3) at high temperatures. Heat exchanger tubes are scaled with this compound, which serious...

This paper analyses how research on antibiotic resistance has been a driving force in the development of new antibiotics. Drug resistance, while being a problem for physicians and patients, offers attractive perspectives for those who research and develop new medicines. It imposes limits on the usability of older medicines and simultaneously modifies pathologies in a way that opens markets for ...

Performances of two common types of red mud, Bayer red mud and Sintering red mud, were investigated in this research. Their compositions, mechanical properties and microstructure characterization were measured through XRD, TG and SEM analysis. Their shear strength, particle size, density and hydraulic characteristics also had been performed. Huge differences between the basic mineral types of t...

In 2008, the University of Cologne and Bayer Schering Pharma together decided to establish a "privileged partnership" in order to foster interactions in the field of preclinical and clinical drug discovery and development. As one of the activities of this partnership, we launched a graduate program run by the University and supported by Bayer funds. Founded in 2009, the program now provides adm...
