A total of 86 species of vascular plants have been found in the studied territories along the highways of Nizhny Novgorod. Asteraceae, Poaceae, and Fabaceae play a great role in the taxonomic structure of herbs. Cyperaceae and Rosaceae are less important. Among the ecologocenotical groups, meadow species form the basis of the herbaceous cover, but their participation diminishes at distances of 1–3 m from the highways. Herbaceous plants include also flowering meadow species, which play an indispensable aesthetic role. © 2016, Pleiades Publishing, Inc.

Aims Alcohol-exposed pregnancies (AEP) are the direct cause of fetal alcohol spectrum disorders (FASD). This study examines drinking patterns among pregnant and non-pregnant women of childbearing age in Russia, a country with one of the highest levels of alcohol consumption in the world. Design Cross-sectional survey. Setting Seven public women's clinics in two locations: St Petersburg (SPB) and the Nizhny Novgorod region (NNR). Participants A total of 648 pregnant and non-pregnant childbearing-age women. Measurements A face-to-face structured interview assessed alcohol consumption, pregnancy status/possibility of becoming pregnant and consumption before and after pregnancy recognition. Findings Eighty-nine per cent of non-pregnant women reported consuming alcohol and 65% reported binge drinking in the past 3 months; 47% in NNR and 28% in SPB reported binges at least monthly. Women who might become pregnant consumed alcohol similarly to women who were not likely to become pregnant, and 32% of women in SPB and 54% in NNR were categorized as at risk for AEP. There was a significant decline in drinking after pregnancy identification. Twenty per cent of pregnant women reported consuming alcohol and 6% in SBP (none in NNR) reported binge drinking; however, a high prevalence of binge drinking was found among women who might become pregnant or who were trying to conceive. Conclusions Russian women substantially reduce drinking after pregnancy recognition compared to pre-pregnancy levels. No reductions were found prior to pregnancy recognition, either when a woman might become pregnant or when she was trying to conceive. The pre-conception period presents a risk window and, therefore, a prevention opportunity. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

Introduction: Low rates of contraception and at-risk drinking place many Russian women at risk of an alcohol-exposed pregnancy (AEP). The only realistic way to determine when women are at risk of AEP is by self-reports. A U.S. study found that a single binge-drinking question (SBD) effectively identified nearly all women whose drinking placed them at risk of AEP. Methods: The present study replicated the U.S. study. Participants were 689 non-pregnant Russian women of childbearing age who were at AEP risk. Their answers to SBD, "During the previous three months, how often did you have four or more drinks on one occasion", were compared with their reports of binge drinking on a 90-day Timeline Followback (TLFB) calendar. Results: The SBD identified 99% of at-risk Russian women as binge drinkers, replicating U.S. findings. Only 8% of the women were identified at-risk using a second AEP criterion of ≥ 8 drinks on average per week. Although Russian women did not report heavy weekly drinking and two-thirds did not meet AUDIT criteria for problem drinking, when they did drink, 40% of the time it was binge drinking. Conclusions: Almost all Russian women who were at risk of an AEP were identified by a single binge-drinking question. Results from this study suggest that Russian health care practitioners can use SBD to successfully screen women for AEP risk. SBD identified 99% of Russian women who were at AEP risk. Consequently, it is recommended that SBD be incorporated into routine health care © 2015 Elsevier Ltd.

The artificial neural network technique is applied to dividing discontinuities in space plasma and magnetic field parameters into classes corresponding to known types of magnetohydrodynamic discontinuities. Parameter discontinuities registered on the WIND spacecraft between 1996 and 1999 are classified using a network of the Kohonen Layer type. An algorithm for determining the orientation of discontinuity surfaces on the basis of one-dimensional observations of solar wind parameter discontinuities on board spacecraft is proposed. © 2010 Pleiades Publishing, Ltd.

We obtain dispersion relations for magnetogravity waves in the ionosphere with allowance for the combined influence of magnetic field, gravity, and finite conductivity within the framework of the hydrodynamic approximation. The required conditions are fulfilled in the ionosphere at altitudes over or about 250 km. The auroral electrojet is considered as a source of magnetogravity waves which are frequently observed as traveling ionospheric disturbances. The contribution of magnetogravity waves to the ionospheric disturbances is determined on the basis of analyzing the data from the vertical sounding of the ionospheric F2 layer and the geomagnetic disturbances along the chosen magnetic meridian and on its sides. The features of the obtained dynamic spectra of magnetogravity waves agree with the characteristic frequencies and velocities determined by the calculated dispersion curves. As a result, we confirm the fact that magnetogravity waves stipulate some traveling ionospheric disturbances and can be used for diagnostics of the ionospheric parameters. © 2012 Springer Science+Business Media New York.

The possibility of magnetogravity wave (MGW) propagation in the equatorial ionosphere taking into account the finite conductivity is analyzed. The dispersion relation shows the existence of two propagating MGW modes in ionospheric layer F2: high-frequency (HF MGW) and low frequency (LF MGW). The dispersion relations for them are executed and the characteristic frequencies and propagation velocities are determined. In this part of research the spectral features of disturbances in components of environment displacement for HF MGW, generated by a mass source, is carried out. The results are applied to estimate the values of density, pressure and magnetic field spectral components of magnetogravity disturbances caused by horizontal meteor sweep. They may be useful in the analysis of ionospheric disturbances excited by high energy geophysical sources. © 2014, Pleiades Publishing, Ltd.

Research to the identification of plasma flows in the Solar wind by spectral characteristics of solar plasma flows in the range of magnetohydrodynamics is devoted. To do this, the wavelet skeleton pattern of Solar wind parameters recorded on Earth orbit by patrol spacecraft and then executed their neural network classification differentiated by bandwidths is carry out. This analysis of spectral features of Solar plasma flows in the form of magnetic clouds (MC), corotating interaction regions (CIR), shock waves (Shocks) and highspeed streams from coronal holes (HSS) was made. The proposed data processing and the original correlation-spectral method for processing information about the Solar wind flows for further classification as online monitoring of near space can be used. This approach will allow on early stages in the Solar wind flow detect geoeffective structure to predict global geomagnetic disturbances. © Pleiades Publishing, Ltd 2014.

In the first part of study the possibility of high frequency (HF) and low frequency (LF) modes of magnetogravity waves (MGW) propagation in the equatorial atmosphere in conditions of ionospheric F2 layer is demonstrated taking into account the finite conductivity. Here the spectral features of the excited HF MGW mode is studied. At the second part of study the dispersion relations for LF MGW in the ionospheric equatorial region is received. The spectral features of the disturbed components of medium displacement for LF MGW generated by a mass source are investigated. The results are applied to calculate the values of the spectral components of magnetogravity density, pressure and magnetic field disturbances caused by horizontal meteor sweep. The estimates may be useful in the analysis of ionospheric disturbances excited by high-energy geophysical sources. © Pleiades Publishing, Ltd 2014.

The objective of the co-authors is to study the motivation of purchasers of construction/finishing materials and the criteria that govern their selection. No systemic studies of consumer behavioral models and stereotypes in respect of residential housing have been performed so far. However, the environmentally determined management techniques, applicable to the production of building materials and construction of residential housing, are highly relevant both worldwide and in the Russian Federation. The co-authors have developed an original research methodology, drafted a questionnaire, and conducted a pilot survey. Its findings have proven that the price and quality of construction materials are the main factors that influence the decision making process in favor of particular items. Mere 14% of the respondents chose environmental friendliness as the decision making criterion. The findings of the focus group projects have also proven the trustworthiness of the stereotypes and behavioral models identified by the co-authors. The co-authors make a conclusion that further sociological surveys are needed to implement the patterns of environmentally determined management and to influence the value paradigms of the population. © 2016 The Authors, published by EDP Sciences.
