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.

The article presents the results of studying the subjectivity structure in teenagers with different level of computer game addiction. The subjectivity structure as integrative property, expressed in the attitude of a human to himself as a doer, as well as conscious and deedful attitude to the world and himself in this world, was diagnosed by the questionnaire about "Subjectivity structure of younger teenager". The subjectivity structure was defined as a level of expression of its components: activity, awareness of the ability to reflect, freedom of choice and responsibility for it, awareness of their own uniqueness, understanding and acceptance of the other, and self-development. The authors analyzed the subjectivity features of teenagers of different gender "addicted" and just "interested" in computer games. Younger teenagers with a high level of computer game addiction have lower rates of developing subjectivity components such as the development of conscious activity, the ability to reflect, ability to understand and accept another person. The article describes subjectivity components allowing to neutralize the negative effects of the existing computer game addiction in teenagers and to reduce the risk of its rise to a high level. © 2017, Pharmainfo Publications.

We describe a simple experiment giving the opportunity to estimate the time of collision of a freely falling ping-pong ball and a table. The method is based on the ball deformation measurement and uses just elementary geometry and kinematics. © 2016 IOP Publishing Ltd.

We propose a simple experiment on the air density measurement which does not require any special equipment: just an A4 sheet of paper, a stopwatch and a ruler. The discussed method uses the most basic air resistance model. © 2016 IOP Publishing Ltd.

We have measured the critical flicker detection frequency (CFDF) and double pulse recognition threshold (DPT) using three LEDs with power peaks at 460, 525 and 625 nm for target illumination. Brightness equalization was performed by customized heterochromatic flicker photometry (cHFP). Reference luminance levels were 170 cd/m2 (blue LED, 60 subjects), 4 cd/m2 (green LED, 20 subjects), and 1 cd/m2 (green LED, 20 subjects). The measurement at 1 cd/m2 was preceded by 15 min of dark adaptation. The angle of view for the target was 3°, and the duration of stimuli was 1 ms. An experimental pulse generator with three channels and a projector was used. No differences in CFDF at different spectral properties of stimulus were observed at all three levels of luminance. Thus, it is concluded that temporal vision resolution does not depend on the spectral properties of visual stimuli. © 2017, 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.

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.

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.

A gallium(i) carbenoid derived from redox-active diimine 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene (dpp-bian) in complexes with molybdenum may serve either as a neutral [(dpp-bian)Ga:] or an anionic [(dpp-bian)Ga:]- two-electron donor depending on the electronic state of the transition metal.

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.
