Abstract: The paper describes the intervention protocol and addresses questions about the feasibility of a brief FASD prevention intervention delivered by OB/GYN at women's clinics in Russia. Brief physician intervention guidelines and two evidence-based FASD prevention interventions were utilized to design a brief dual-focused physician intervention (DFBPI) appropriate to Russian OB/GYN care. The questions answered were whether trained OB/GYN physicians could feasibly deliver DFBPI during women's routine clinic visits, whether they maintained skills over time in clinical settings, and which specific intervention components were better maintained. Data were collected as part of a larger study aimed at evaluating effectiveness of DFBPI in reducing AEP risk in non-pregnant women. Methods of monitoring the intervention delivery included fidelity check lists (FCL) with the key components of the intervention completed by physicians and patients and live and audio taped observations of intervention sessions. Physicians (N= 23) and women (N= 372) independently completed FCL, and 78 audiotapes were coded.The differences between women's and physicians' reports on individual items were not significant. Although the majority of physician and patient reports were consistent (N=305), a discrepancy existed between the reports in 57 cases. Women reported more intervention components missing compared to physicians (p<0.001). Discussing barriers was the most difficult component for physicians to implement, and OB/GYN demonstrated difficulties in discussing contraception methods.The results supported the feasibility of the DFBPI in Russia. OB/GYN physicians trained in the DFBPI, monitored, and supported were able to implement and maintain skills during the study. In addition to the alcohol focus, DFBPI training needs to have a sufficient component to improve physicians' skills in discussing contraception use.
Weak Interaction and the Nature of Virtual Particles  [PDF]
Vladimir Konushko
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.22009
Abstract: The granular structure of space, the nature of virtual particles and the unity of physical interactions are under study. The mass of an elementary cell in the Universe is determined, as a whole, with the physical meaning of the renormalization procedure changing in this case.
Granular Space and the Problem of Large Numbers  [PDF]
Vladimir Konushko
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.25038
Abstract: Two and a half thousand years ago the ancient atomists made a suggestion that space has a cellular structure, is material and consists of elementary cells. In 1900 Plank found the elementary length L*=10-33 cm. This notion has been widely used in modern physics ever since. The properties of granular space are studied in this article on the assumption that a three-dimensional material cell with the size of Planck’s elementary length is the only material for the construction of the whole Universe. This approach allows one to account for such mysterious phenomena as inertia, ultimate velocity of transfer of material body interactions and huge difference between gravitational and Coulomb forces - the so called “Large Numbers Problem”, as well essence of electric charge and Pauli exclusions principle.
Gravitational Energy Level and the Nature of Microwave Background of Universe  [PDF]
Vladimir Konushko
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.24026
Abstract: In 1965, Penzias and Wilson discovered thermal radiation with T0 ~ 2.7 K further on called “relict”. This article is concerned with the new phenomenon, i.e. the formation of gravitational energy levels by any body, with the result that photons are produced whose spectrum close to the Earth is similar to that of a blackbody with T0 ~ 2.7 K. The critical analysis of the experiments performed with the cosmic observatories COBE and WMAP completely confirms this prediction.
Translational Motion of a Free Large Polaron and Broadening of Absorption Spectra  [PDF]
Vladimir Mukhomorov
Journal of Modern Physics (JMP) , 2010, DOI: 10.4236/jmp.2010.11002
Abstract: The translational motion of a large polaron as whole is analyzed in the context of its effect on the broadening of an absorption optical spectrum. It was open question how important the role of translational degrees of freedom and the corresponding velocities are on the broadening. The Bogolyubov method of canonical transformation of coordinates is formulated for a system of an electron and field, taking into account rigorous fulfillment of the conservation laws. Separation of variables is carried out for the coordinates describing the translational degrees of freedom and the electron oscillations in a polarization well. The equations obtained for the electronic states explicitly depend on the velocity of the free polaron as a whole. An estimate is made for free polaron in ammonia.

Vladimir Voronov
Natural Science (NS) , 2010, DOI: 10.4236/ns.2010.28114
Abstract: In the present work a possibility of computation modeling, which should be realized in a real quantum computer, is discussed. In this connection two models of a device, which work is determined by the structure and dynamics of real molecular systems are reported.
Stability of Atoms, Causality in Elementary Processes and the mystery of Interference and Hyroscope  [PDF]
Vladimir Konushko
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.33032
Abstract: An investigation into real structure of space allows solving in a new way the problem of stability of atom: an electron on the ground level is a rest. The absolute causality of all the phenomena in the Universe is substantiated. Heisenberg inequalities make some sense only when it is impossible to conjugated physical values. The work is concern with the mystery of interference and hyroscope.
Universe, Dark Energy and Dark Matter  [PDF]
Vladimir Konushko
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.311227
Abstract: The investigations into the structure of the gravitation field formed by stars, galaxies and their clusters have allowed an alternative explanation for the effect of red shift in stellar spectra; they also have “stopped” the expansion of the Universe and disregarded “dark” energy (DE). The characteristic features of the structure of gravitational field for large galaxies give a clear indication of the mysterious “dark” matter (DM) which enables eliminating it in the Universe. And, finally, the theory of granular space may prove the existence of the Universe as a unique one.
Classical SU(3) Gauge Field as a Dark Matter  [PDF]
Vladimir Dzhunushaliev
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.48A010

The model of dark matter is presented where the dark matter is a classical gauge field. A spherical symmetric solution of Yang-Mills equation is obtained. The asymptotic behavior of the gauge fields and matter density is investigated. It is shown that the distribution of the matter density allows us interpret it as the dark matter. The fitting of a typical rotational curve with the rotational curve created by the spherical solution of SU(3) Yang-Mills equation is made

Dark Energy as a Vacuum Component of the Universe  [PDF]
Vladimir Burdyuzha
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.49160

The vacuum component of the Universe is investigated in both the quantum and the classical regimes of its evolution. The associated vacuum energy density was reduced by more than 78 orders of magnitude in 10-6 sec in the quantum regime and by nearly 45 orders of magnitude in 4 × 1017 sec in the classical regime. The vacuum energy was spent for the organization of new microstates during the expansion of the Universe. In the quantum regime, phase transitions were more effective in reducing the vacuum energy than in producing new microstates. Both of these phenomena have been recorded in the history of the Universe. Herein, the need for the evolution of the Universe’s vacuum component is discussed. Indeed, through this evolution, all 123 crisis orders of dark energy are reduced by conventional physical processes. A table of the vacuum energy’s evolution as the function of red shift and a short discussion about vacuum stability are presented.
