В отделение поступил 32-летний мужчина, не имеющий других заболеваний, кроме жалоб на боль в области ребер справа и в области груди после подъема тяжелого предмета. Пациент также сообщил о нескольких переломах ребер год тому назад, ранее связываемых с кашлем. При осмотре у пациента обнаружена болезненность ребер с обеих сторон. Рентген грудной клетки показал множественные сросшиеся переломы шес...

In the framework of effective-mass envelope function theory, including the effect of Rashba spin-orbit coupling, the binding energy E(b) and spin-orbit split energy Г of the ground state of a hydrogenic donor impurity in AlGaN/GaN triangle-shaped potential heterointerface are calculated. We find that with the electric field of the heterojunction increasing, (1) the effective width of quantum we...

The author analyzes tendencies of development of payment institutes and prospect of creation of the International financial Centre in Russia on the basis of primary development of e-commerce in spheres B2C and С2С. The author proves, that in the conditions of globalization of the consumer markets the analys...

This paper discusses the Flow-Orientation Problem (FOP), which assigns orientations of all links of an undirected network to obtain a directed network for meeting some flow optimization measurements. First, we describe the background and define three related FOP issues: MDFOP, MDSFOP, and MDDFOP. We discuss the complexity of the FOP on general networks, and also list the essences of convex-spli...

Nanocrystalline hafnium oxide (HfO2) thin films have been produced under variable reactive oxygen (O2) fractionation (Г) employing Hf metal for reactive sputter-deposition. The effect of Г on the HfO2 compound formation, structure, morphology and optical properties has been evaluated. Without oxygen, the films of hexagonal phase of Hf metal were grown. Films grown at different O2 pressure are n...

A diamond-structured photonic crystal (PC) with graded air spheres radii was fabricated successfully by stereolithography (SL) and gel-casting process. The graded radii in photonic crystal were formed by uniting different radii in photonic crystals with a uniform radius together along the Г‑Х direction. The stop band was observed between 26.1 GHz and 34.3 GHz by reflection and transmission meas...

We crossed the C3 species Atriplex prostrata with the C4 species Atriplex rosea to produce F1 and F2 hybrids. All hybrids exhibited C3-like δ(13)C values, and had reduced rates of net CO2 assimilation compared with A. prostrata. The activities of the major C4 cycle enzymes PEP carboxylase, NAD-malic enzyme, and pyruvate-Pi dikinase in the hybrids were at most 36% of the C4 values. These results...
