    Water suspensions of in-organic (metals and oxides) and organic nano-objects (chitozan and collagen) were subjected to the treatment of direct and alternative electrical fields. In addition to quasi-periodical spatial patterning resonance-like performance of spatial distributions of these suspensions has been found at low frequencies of alternating electrical field. These resonances are explained as the result of creation of equilibrium states of groups of charged nano-objects with opposite signs of charges at the interparticle distances where the forces of Coulomb attraction are compensated by the repulsion forces induced by relatively negative polarization of hydrated regions surrounding the nanoparticles with respect to pure water. The low frequencies of these resonances are explained by comparatively big distances between the particles and their big masses with t\respect to masses of atoms constituting molecules with high resonance frequencies. These new resonances open a new approach to detailed modeling and understanding of mechanisms of the influence of electrical fields on the functioning of internal organs of living organisms at the level of cells and neurons

    Lost in translation: case study of interpreting American SBUs by Russian EFL learners majoring in linguistics

    Get PDF
    The paper investigates difficulties Russian EFL learners have in interpreting American situation-bound utterances (SBUs). A case study involving 75 linguistics students translating SBUs is described. Their acceptable translations and mistakes in the interpretation of SBUs are analyzed and recommendations to improve teaching translation are given. A classification of SBUs is worked out for this purpose

    Interacting Bose and Fermi gases in low dimensions and the Riemann hypothesis

    Full text link
    We apply the S-matrix based finite temperature formalism to non-relativistic Bose and Fermi gases in 1+1 and 2+1 dimensions. In the 2+1 dimensional case, the free energy is given in terms of Roger's dilogarithm in a way analagous to the relativistic 1+1 dimensional case. The 1d fermionic case with a quasi-periodic 2-body potential provides a physical framework for understanding the Riemann hypothesis.Comment: version 3: additional appendix explains how the Ξ½\nu to 1βˆ’Ξ½1-\nu duality of Riemann's ΞΆ(Ξ½)\zeta (\nu) follows from a special modular transformation in a massless relativistic theor

    Combined algorithm of the realization of the method of least modules.

    Full text link
    The methods of software realization of the approximate method of calculating the estimates of the smallest modules (the Mudrov method), the combined method of variational-weighted quadratic approximations and coordinate-wise descent, and the method of search for estimating the coefficients of linear regression models are considered. Based on the results of the study, it was found that the root-mean-square deviation in calculating the coefficients of the linear function y (x) = kx + b in the combined method is less than in calculating the coefficients by the Mudrov method.РассмотрСны способы ΠΏΡ€ΠΎΠ³Ρ€Π°ΠΌΠΌΠ½ΠΎΠΉ Ρ€Π΅Π°Π»ΠΈΠ·Π°Ρ†ΠΈΠΈ ΠΏΡ€ΠΈΠ±Π»ΠΈΠΆΠ΅Π½Π½ΠΎΠ³ΠΎ ΠΌΠ΅Ρ‚ΠΎΠ΄Π° вычислСния ΠΎΡ†Π΅Π½ΠΎΠΊ Π½Π°ΠΈΠΌΠ΅Π½ΡŒΡˆΠΈΡ… ΠΌΠΎΠ΄ΡƒΠ»Π΅ΠΉ (ΠΌΠ΅Ρ‚ΠΎΠ΄Π° ΠœΡƒΠ΄Ρ€ΠΎΠ²Π°), ΠΊΠΎΠΌΠ±ΠΈΠ½ΠΈΡ€ΠΎΠ²Π°Π½Π½ΠΎΠ³ΠΎ ΠΌΠ΅Ρ‚ΠΎΠ΄Π° Π²Π°Ρ€ΠΈΠ°Ρ†ΠΈΠΎΠ½Π½ΠΎ-Π²Π·Π²Π΅ΡˆΠ΅Π½Π½Ρ‹Ρ… ΠΊΠ²Π°Π΄Ρ€Π°Ρ‚ΠΈΡ‡Π½Ρ‹Ρ… ΠΏΡ€ΠΈΠ±Π»ΠΈΠΆΠ΅Π½ΠΈΠΉ ΠΈ ΠΏΠΎΠΊΠΎΠΎΡ€Π΄ΠΈΠ½Π°Ρ‚Π½ΠΎΠ³ΠΎ спуска ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Π° ΠΏΠ΅Ρ€Π΅Π±ΠΎΡ€Π° для оцСнивания коэффициСнтов Π»ΠΈΠ½Π΅ΠΉΠ½Ρ‹Ρ… рСгрСссионных ΠΌΠΎΠ΄Π΅Π»Π΅ΠΉ.

    WHAT DO WE KNOW ABOUT NOCTURNAL ACTIVITY OF MOOSE?

    Get PDF
    Study of activity and behavior of moose (Alces alces) has generally been undertaken during daylight hours because research at night is logistically complicated. However, some believe that moose are as or more active at night than day, thus, the amount and content of research about moose activity could be considered diurnally-biased. We conducted a review of the literature to determine what is known regarding nocturnal activity of moose and found that only 2.2% of all articles published about moose activity and behavior refer to nocturnal activity. Studies designed specifically to document nocturnal activity were mostly related to moose-vehicle collisions and use of mineral licks. Recent and increased use of GPS radio-collars will provide more and easier opportunities to distinguish and analyze diurnal and nocturnal activity of moose. Such information is important to understand better a variety of aspects of moose behavior and activity including predator-prey interactions, influence of human disturbances, relationships among habitat use, thermal stress, and climate change
