The metabolic capability of denitrifying sludge to oxidize ammonium and p-cresol was evaluated in batch cultures. Ammonium oxidation was studied in presence of nitrite and/or p-cresol by 55 hours. At 50 mg/L NH4 + -N and 76 mg/L NO2 -N, the substrates were consumed at 100% and 95%, respectively, being N2 the product. At 50 mg/L NH4 + -N and 133 mg/L NO2 -N, the consumption efficiencies decrease...

We describe a new photonic-crystal structure with a complete three-dimensional photonic band gap (PBG) and its potential application to integrated optics. The structure not only has a large band gap and is amenable to layer-by-layer litho-fabrication, but also introduces the feature of high-symmetry planar layers resembling two-dimensional photonic crystals. This feature enables integrated opti...

Today's level of integrated use minerals and beneficiation wastes in Ukraine, particular, at the Kryvbas GOK, is unsatisfactory, as it generally allowing production additional types construction products. The volume mining growing, but only a small percentage extracted transferred to finished product. residue form waste returned environment, polluting it. reason for this lack technology mineral...

ABSTRACT Progression to major acute cardiovascular events often is triggered by an atherosclerotic plaque complicated by rupture or erosion, namely the vulnerable plaque. Early and secure identification of these plaques would allow the development of individualized therapeutic and pharmacological strategies, applied in a timely manner. Imaging methods have a huge potential in detecting and moni...

For more than 70 years, the inhibitors of carbonic anhydrase (ICA) have been used in treatment glaucoma. Since 1995, topical forms ICA appeared among antiglaucoma drugs — dorzolamide, and since 1999 brinzolamide. The hypotensive efficacy safety gave rise to widespread use these various peculiarities mechanism action made it possible create on their basis effective fixed combinations, which allo...
