Erdélyi magyar pedagógusok Magyarországra történő áttelepedése a szakirodalom tükrében

A rendszerváltást követően Románia területéről, főleg Erdélyből sok magyar nemzetiségű ember döntött úgy, hogy áttelepül Magyarországra. Több migrációs kutatás feladatul tűzte ki, hogy számszerűsíti a kivándorolt populáció nagyságát, nem és korosztályhoz való tartozását. A kivándorolt populáció végzettségét illetően, viszont kevés felmérés, kutatás született, valószínűleg azért is, mert a kivándoroltak nem maradtak meg a képzésüknek megfelelő pályán, nem honosították a diplomáikat, illetve nehéz feladatnak bizonyult az áttelepedettek szakmai nyomon követése

Functional differentiation under simultaneous conservation constraints (Constrained functional differentiation in statistical physics and hydrodynamics)

Analytical formulae for functional differentiation under simultaneous K-conservation constraints, with K the integral of some function of the functional variable, are derived, making the proper account for the simultaneous conservation of normalization and statistical averages, e.g., possible in functional differentiation in nonvariationally built physical theories, which gets particular relevance for nonequilibrium, time-dependent theories.Comment: final version, published in J Phys A; 14 pages; with (34)-(35) and a note after (10) added (to v3

Synthesis of Spinel Ferrites in Radiofrequency Thermal Plasma Reactor

Formation of nanosized zinc-ferrites and nickel-zinc ferrites from iron- and zinc oxide powders and corresponding nitrate solutions, respectively, was studied in RF thermal plasma conditions. The products were characterized for chemical composition, phase conditions, particle size distribution, morphologies and saturation magnetization. Effects of synthesis conditions on properties of products were studied in details

Synthesis of Zinc Ferrites in RF Thermal Plasma Reactor

Formation of nanosized zinc ferrite spinels was studied from iron- and zinc oxide powders and corresponding nitrate solutions, respectively in a radiofrequency thermal plasma reactor. From the viewpoint of applications, the research was motivated by the potential use of these materials in advanced magnetic devices on the one hand, and by their biomedical applications such as drug carriers or agents for cancer treatment by hyperthermia on the other. In this work effects of synthesis conditions on properties of products were studied in details. The products were characterised for chemical composition, phase conditions, particle size distribution, morphologies and saturation magnetisation. Most products exhibited ferrimagnetic behaviour. Correlations among domain- and particle sizes were also investigated. Conditions for the synthesis of nanosized, inverse zinc ferrites of high saturation magnetisation were established. It was proved that in thermal plasma conditions normal and inverse ferrites could be produced in a single step process
