Fine powders of micron- and submicron-sized particles of undoped Cu(2)O semiconductor, with three different sizes and morphologies, have been synthesized by different chemical processes. These samples include nanospheres 200 nm in diameter, octahedra of size 1 µm and polyhedra of size 800 nm. They exhibit a wide spectrum of magnetic properties. At low temperature, T = 5 K, the octahedron sample...

We present results concerning the synthesis of FexCo1-x (0 < x 1) alloy nanoparticles (NPs) with different compositions by chemical reduction technique and subsequent structural (XRD patterns), morphological (TEM images) magnetic (VSM magnetometry) characterization. have got excellent quality NPs in cubic bcc structure showing a room temperature magnetization as high 235 emu/g for Fe66Co34 comp...

In order to further reduce the aerodynamic drag of High-speed Electric Multiple Units (EMU), an active flow control reduction method combining air suction and blowing is proposed at rear EMU train. A numerical calculation based on realizable k-ε used investigate characteristics a three-car with speed 400 km/h. The influence different suction-blowing mass rates, position number ports surface pre...

In the wake of monetary integration in Europe, Austria abandoned the tested hard currency policy (HCP) for joining EMU as a member. The final target of monetary policy and real sector adjustment needs are similar in both regimes, and the HCP may therefore be viewed as a convenient "training camp" for later EMU accession. Georg Winckler devoted a number of essays on the critique, but also on the...

Decisions about cell survival or death are central components of adaptive immunity and occur at several levels in immune system development and function. The Bcl-2 family of homologous proteins plays an important role in these decisions in lymphoid cells. Bcl-2, Bcl-xL, and A1 are differentially expressed during B- and T-cell development, and they have shared and distinct roles in regulating ce...

Despite anticipated curtailment of their powers, the past decade saw technocratic actors take on an increasingly powerful role in economic governance. Focusing EU, I analyse these epochal shifts as a move away from market liberal paradigm that informed 1992 European Economic and Monetary Union (EMU). The EMU combines highly restrictive attitude to public money creation with permissive laissez-f...
