Microwave-assisted synthesis and catalytic activity of nano-sized molybdenum carbide in naphthalene hydrogenation.

Nanosized molybdenum carbide (β-MoC) synthesized by microwave irradiation method was applied for catalytic hydrogenation of naphthalene. Varying the synthesis conditions affects not only the phase composition and physicochemical properties of the resulting carbide but also makes it possible to regulate the selectivity for hydrogenation products. Samples synthesized in a short time (1-4 min) contain more acid sites due to the presence of molybdenum oxide and allow deeper hydrogenation of naphthalene to decalin compared to a pure-phase molybdenum carbide sample.

Quantitative Homogenization for the Obstacle Problem and Its Free Boundary.

In this manuscript we prove quantitative homogenization results for the obstacle problem with bounded measurable coefficients. As a consequence, large-scale regularity results both for the solution and the free boundary for the heterogeneous obstacle problem are derived.

BALANCE OF Thl/Th2/Th9/Thl7/Th22 CYTOKINES IN POST-OPERATION PERIOD IN PATIENTS WITH MALIGNANT TUMOR OF LIVER.

Aim: Evaluate cytokine status in patients with malignant liver cells after surgery.

Materials And Methods: 33 patients aged 35 to 76 years were included into the study. Blood was obtained before the operation and in the post-operation period: after 6 and 24 hours and at day 7 Cytokine profile (IL-Ib, IL-2, TNF-α, IFN-γ, IL-12p70, IL-4, IL-5,IL-6, IL-10, IL-13, IL-9, I-17a, IL-22) was evaluated using Multiplex- 13 system (Bender MedSystems, Austria).

Stimulation of Erwinia sp. fumarase and aspartase synthesis by changing medium components.

The optimal concentrations of nutrient medium components, aeration conditions, and pH providing for maximum biomass yields, as well as fumarase and L-aspartase activities, during submerged cultivation of Erwinia sp. were determined. The data showed that different concentrations of carbon source (molasses) and pH of the nutrient medium were required to reach the maximum fumarase and L-aspartase activities.
