Determinación de la nacionalidad de la entidad jurídica sobre la base de la teoría del control

The purpose of this article is to analyze the theory of control as a specific method of determining the nationality of a legal entity in international private law. The search for the definition and content of the control theory is usually accompanied by the statement that, unlike all other theories, the application of this theory takes into account not the legal entity itself as a whole, but the nationality of natural persons behind it (founders, participants). On the basis of the present study, it can be concluded that the theory of control is an exceptional and the only method guaranteeing the determination of the real nationality of the legal person with a view to conferring on it certain rights (benefits, privileges). This also coincides with the protection of state sovereignty and national security as confirmed by numerous examples from practice.El propósito de este artículo es analizar la teoría del control como un método específico para determinar la nacionalidad de una entidad jurídica en el derecho privado internacional.

Sobre la base del presente estudio, se puede concluir que la teoría del control es un método excepcional y único que garantiza la determinación de la nacionalidad real de la persona jurídica con el fin de conferirle ciertos derechos (beneficios, privilegios).

Experimental Study of Sliding Friction for PET Track Membranes

The article is presented results of a study of the process for a dry friction metal-polymer couple on scheme disc-finger. Track membrane from polyethylene terephthalate was a research material. Membrane had pores with 0.4 and 0.8 μm diameters. The effect of the sliding velocity for membranes with pores of 0.8 microns was determined. Research was shown that increasing pore's diameter caused a reduction of the friction coefficient and downturn its magnitude vibrations. The study showed that track membrane have adequate resistance to wear and can be successfully used in surgical procedures in the layers of the cornea

Studying temporal variability of GRS1739-278 during the 2014 outburst

We report a discovery of low-frequency quasi periodic oscillation at 0.3-0.7 Hz in the power spectra of the accreting black hole GRS1739-278 in the hard-intermediate state during its 2014 outburst based on the ${\it NuSTAR}$ and Swift/XRT data. The QPO frequency strongly evolved with the source flux during the NuSTAR observation. The source spectrum became softer with rising QPO frequency and simultaneous increasing of the power-law index and decreasing of the cut-off energy. In the power spectrum, a prominent harmonic is clearly seen together with the main QPO peak. The fluxes in the soft and the hard X-ray bands are coherent, however, the coherence drops for the energy bands separated by larger gaps. The phase-lags are generally positive (hard) in the 0.1-3 Hz frequency range, and negative below 0.1 Hz. The accretion disc inner radius estimated with the relativistic reflection spectral model appears to be $R_{\rm in} < 7.3 R_{\rm g}$. In the framework of the relativistic precession model, in order to satisfy the constraints from the observed QPO frequency and the accretion disc truncation radius, a massive black hole with $M_{\rm BH} \approx 100$M$_\odot$ is required.Comment: 15 pages, 12 figures; accepted for publication in MNRA
