Combination of Ceramic Laser Micromachining and Printed Technology as a Way for Rapid Prototyping Semiconductor Gas Sensors.

The work describes a fast and flexible micro/nano fabrication and manufacturing method for ceramic Micro-electromechanical systems (MEMS)sensors. Rapid prototyping techniques are demonstrated for metal oxide sensor fabrication in the form of a complete MEMS device, which could be used as a compact miniaturized surface mount devices package. Ceramic MEMS were fabricated by the laser micromilling of already pre-sintered monolithic materials.

Influence of Electrode Design and Contacting Layers on Performance of Electrolyte Supported SOFC/SOEC Single Cells.

The solid oxide cell is a basis for highly efficient and reversible electrochemical energy conversion. A single cell based on a planar electrolyte substrate as support (ESC) is often utilized for SOFC/SOEC stack manufacturing and fulfills necessary requirements for application in small, medium and large scale fuel cell and electrolysis systems. Thickness of the electrolyte substrate, and its ionic conductivity limits the power density of the ESC.

[Some proteins of acute phase of inflammation in differential diagnostics of rheumatoid arthritis].

Levels of lactoferrin (LF), antithrombin-III (AT-III) and beta2-macroglobulin (MG) in blood of patients with rheumatoid arthritis (RA), reactive arthritis (ReA) and systemic lupus erythematosus (SLE) were examined for assessment their importance in differential diagnostics of the diseases. It was shown that on the average, LF and AT-III levels were increased at RA, while MG level was practically unchanged. At the same time LF level was stable high regardless of RA activity and duration degree, but its concentration was significantly increased also in ReA patients (33% patients).

[The clinico-electrocardiographic classification of the early ventricular repolarization syndrome].

Based on an analysis of 4980 ECGs of patients, the authors could distinguish and classify the clinico-electrocardiographic versions of the early ventricular repolarization syndrome (EVRS): permanent, occurring for the first time, suddenly disappearing, intermittent with a gigantic T wave; with a negative T wave, with a short-term T wave inversion, marked by the combination with Wolff-Parkinson-White syndrome, and additional chordae of the left ventricle. The clinico-electrocardiographic classification of the EVRS is of paramount importance for practitioners owing to an assumption that the EVRS is not only a version of the normal ECG but also can be a marker of CHD. The authors view the EVRS as an independent version of the preexcitation syndrome along with Wolff-Parkinson-White and CLK syndromes, with the manifestations of which it may combine.
