В рамках моделі граткового газу з урахуванням взаємодії міжвузловинних атомів в першій та другій координаційних сферах для аустенітного сплаву Fe-C за допомогою комп'ютерного моделювання методом Монте-Карло оцінено енергії взаємодії C-C, що одночасно задовольняють мессбауерівські дані з відносної долі атомів заліза з різним оточенням атомами вуглецю та дані з термодинамічної активності вуглецю.

Single crystal samples of near-stoichiometric Ni2MnGa alloys with giant magnetic field induced strain (MSM effect) at room temperature have been investigated. It was found that there is a reversible reorientation of easy magnetization direction under an applied magnetic field. By means of X-ray Laue diffraction method and diffractometric analysis it was ascertained that these phenomena are connected with the growth of martensitic twin variant with the short crystallographic axis (c-axis) directed along the applied magnetic field. Furthermore, by means of magneto-optical studies the correlation between the change of the martensite microstructure and the change of the magnetic domain structure was found. The field-induced reorientation of martensite variants was able to produce deformation close to the value of (1-c/a), where с and a are the lattice parameters of the tetragonal martensite.

Genotypes at the gliadin loci Gli-A1, Gli-B1, Gli-D1 and the high-molecular-weight glutenin subunit loci Glu-A1, Glu-B1, Glu-D1 were identified in 77 winter common wheat cultivars developed in the Central Forest-Steppe of Ukraine in different periods of time. The highest level of variation was observed at the Gli-A1 locus. Predominant alleles (one or two per locus) were revealed. The comparison of allele frequencies in groups of cultivars developed in different periods of time (before 1996 and in 1996 - 2007) has demonstrated appearance of new alleles and change of frequencies of existing alleles at the storage protein loci. The high frequency of cultivars with the wheat-rye 1BL/1RS translocation was detected (about 40 %). The wheat rye 1AL/1RS translocation was identified in six cultivars developed in the last decade. Four gliadin alleles, Gli-A1w (a marker for the 1AL/1RS translocation), Gli-A1x, Gli-A1y and Gli-B1x, were proposed for cataloging.
