Abstract Magnetic properties of the R11Pd4In9 compounds (R = Y, Gd–Er) were investigated by means of X-ray diffraction and magnetic measurements. Three of these compounds, namely those with R = Y, Ho and Er, are newly synthesized. The compounds crystallize in the orthor...

In the article the analysis of experience and best practices of Europe and the world regarding the methods and tools of risk management in customs affairs. In accordance with the requirements of the Kyoto Convention the risk management is the main basic principle of mod...

The main aim of this work was to evaluate the effect of doxorubicin in complex with C60 fullerene (C60 + Dox) on the growth and metastasis of Lewis lung carcinoma in mice and to perform a primary screening of the potential mechanisms of C60 + Dox complex action. We foun...

As a contribution to electronic transport within strongly spin-polarized surface states and its modification by adsorption of magnetic impurities we studied the adsorption of Tb (atomic magnetic moment 10 μB) on epitaxial Bi(111) films by means of surface sensitive (mag...

<jats:p>Some models of the formation of acoustic emission signals by the destruction of composite material by shear load were examined. We have formulated a mathematical description of the quantity of elements that remains in the process of composite destruction and mat...

The mobility and the diffusivity of a dimer (two atoms coupled by an elastic spring) in a periodic substrate potential under the action of the dc and ac external forces are studied. It is shown that the dimer diffusivity may be strongly enhanced due to driving.

<jats:p>Analysis of the most common foreign methods showed that they were designed to analyze enterprises in the sustainable economic development with low-shadowing of the economy. The most appropriate retrospective analysis results were obtained using Springate model, ...

Formulation of the problem. One of the main features of modern tourism is the concept of its development based on sustainable development. Ecotourism, provided cultural approach to its organization, is an important means to improve the level of ecological culture of soc...

Applications of the hairy ball theorem to the geometrical optics are discussed. When the ideal mirror, topologically equivalent to a sphere, is illuminated at every point, the “hairy ball theorem” prescribes the existence of at least one point at which the incident ligh...
