Climate is a main component of nature that, in addition to being a valuable resource, determines the possibility of development of tourism. Apparently, climate and its characteristics determine touristic demand. Choosing a place for vacation or recreation, tourists primarily prefer an optimal climate and weather conditions. Human-biometeorological resources characterize the connection of climate with a thermal state and health of humans, peculiarities of recreation and health evaluation of the environment. In order to distinguish thermal bioclimate, the physiologically equivalent temperature is used, based on the various meteorological parameters (air temperature, relative humidity, wind speed and radiation) that reflect the human conditions and the thermal comfort perception. In addition for the analysis of the climatic tourism potential, the Climate-Transfer/Tourism-Information Scheme was applied. The results can be useful for tourists in order to determine the best time to take a vacation based on their recreational activity such as sports, medical, health (thalassotherapy, heliotherapy, balneology etc.) according to bioclimatic conditions and their own preferences. © 2015 Swedish Society for Anthropology and Geograph.

Interaction of mefenamic acid [2-(2,3-dimethylphenyl)aminobenzoic acid, maH] with piperazine (ppz), 1,4,7,10-tetraazacyclododecane (cyclen), meso-5,7,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane (teta), and tris(hydroxymethyl)aminomethane (tris) resulted in crystalline proton-transfer complexes of the compositions (ppzH2)(ma)2·4H 2O 1, (cyclenH2)(ma)2·2H2O 2, (tetaH2)(ma)2·2H2O 3, and (trisH)(ma)·H2O 4. Immediate cation-anion hydrogen bonds and those mediated by water molecules are the prime driving forces for the maH and amine assembly. Persistent CH⋯π interactions involving the aromatic rings were found to play an important role in the formation of final structures. All complexes reveal the pronounced segregation of hydrophilic and hydrophobic regions. © 2010 American Chemical Society.

The asymmetric isonaphthalene imide, 3-[(4-nitrophenyl)imino]-1H,3H- benzo[de]isochromen-1-one was obtained by condensation of 1,8-naphthoylchloride with p-nitroaniline in the presence of pyridine. The crystal structure and vibrational and electronic absorption spectra are reported. The emission spectrum of the crystalline phase demonstrates dual luminescence, with short and long wavelength components, while only the short wavelength component is present in chloroform solution. The geometrical and electronic structures of the ground and excited states of the molecule are investigated using density functional theory methods. Dual fluorescence is explained in terms of the excited states of different nature. The spectroscopic properties of newly synthesized compounds for possible biosensor applications are discussed. © 2013 American Chemical Society.

Issue: The environmental issue of concern of the LAGOONS project is the anthropogenic deterioration and climate change impacts - especially the effects of extreme weather events- on surface water and lagoons ecosystems. Objectives: The main objective of the LAGOONS project is to contribute to a science-based seamless strategy - in an integrated and coordinated fashion - of the management of lagoons seen under the land-sea and science-policy-stakeholder interface; i.e., the project seek to underpin the integration of the EU Water Framework Directive, Habitat Directive, the EUs ICZM Recommendation, and the EU Marine Strategy Directive. Methodology: Four case study lagoons have been selected to represent a set of hotspot coastal lagoons with a wide and balanced geographical distribution and different characteristics. The lagoons included are: Vistula Lagoon in Baltic Sea (transboundary Poland/Russia); Tylygulskyi Lagoon in Black Sea (Ukraine); Ria de Aveiro Lagoon in Atlantic Ocean (Portugal), and Mar Menor in the Mediterranean Sea (Spain). By means of elaborating integrated strategies for sustainable development of the case study lagoons in the climate change context, the LAGOONS project will contribute to the goals of the Call showing that it is possible to enhance connectivity between research and policy-making in a lagoons context using a proactive approach to water issues, which assures more efficient use of existing research results. Impact: In management terms, LAGOONS will contribute to the decision-support methodologies for a coordinated approach to the Water Framework Directive and the Marine Strategy Directive. In addition, LAGOONS will propose actions to tackle bottlenecks in the context of climate change, i.e., LAGOONS will propose actions foreseen in the goals of the Europe 2020 strategy - A strategy for smart, sustainable and inclusive growth.

The consistent relativistic energy approach to atoms in a strong realistic laser field, based on the Gell-Mann and Low S-matrix formalism, is applied in the study of resonant multiphoton ionization of krypton by intense uv laser radiation and for the computation of the resonance shift and width in krypton. The approach to the treatment of the multiphoton resonances in nuclei is outlined for the 57Fe nucleus. © Published under licence by IOP Publishing Ltd.

Theoretical studies of Rydberg autoionization resonances in spectra of lanthanides atoms (ytterbium) are carried out within the relativistic many-body perturbation theory in the generalized relativistic energy approach (Gell-Mann and Low S-matrix formalism). The accurate theoretical results on the autoionization 4f13[2F7/2]6s2np[5/2]2, 4f13 [2F7/2] 6s2nf[5/2]2resonances energies and widths are presented and compared with experimental data, obtained by using laser polarization spectroscopy method. © Published under licence by IOP Publishing Ltd.

General problems of electronic conductivity, reasons for a current flow, the role of electrochemical potentials, Fermi functions, the Fermi window for conduction, the elastic resistor model, different electron transport regimes, conduction modes, and transmission coefficients are discussed in terms of the "bottom-up" approach to nanoelectronics. The generalized model of electron transport in the linear response regime developed by R. Landauer, S. Datta, and M. Lundstrom, which can be applied to conductors of any size, scale, and arbitrary dispersion in the ballistic, quasi-ballistic, or diffusive regimes is described. © 2014 Pleiades Publishing, Ltd.

Based on the Landauer-Datta-Lundstrom transport model, the generalized model of heat transfer by phonons is formulated. Similarly to the Fermi window for electron conductivity, the concept of the Fermi window for phonon conductivity is introduced and used to obtain the general expression for the lattice thermal conductivity with the quantum of thermal conductance appearing at the very beginning. There are emphasized the similarity and differences in the construction of the theory of electron conductivity and the theory of heat conduction. There are discussed the thermal conductivity of the conductors, the physical sense of proportionality between the thermal conductivity and the specific heat capacity at constant volume, the relationship between the transmission coefficient and the mean-free-path, the calculation of the number of phonon modes and density of phonon states, the Debye model of heat conductivity and scattering of phonons, the temperature dependence of the lattice thermal conductivity, the difference between the lattice thermal conductivity and electron conduction, and quantization of thermal conductivity.

Purpose of the paper is to provide preliminary assessment of wind resources for different regions of Ukraine. Investigation is based on thirty-minute wind observations collected through an 8-year period (2001 to 2008) for seven airports of Ukraine. By applying of probabilistic analysis techniques to wind data series, different temporal variations of wind speed and direction are derived. The statistic characteristics obtained were compared with the correspondent values provided for 1936-1960 and 1961-1990 periods and site-related temporal changeability is determined.

The variations of total ozone column over Europe at the multiyear time scale have earlier been characterised by the changes in the phase of North Atlantic Oscillation. Spatial patterns over Europe in total ozone column response to weather pattern changes associated with the North Atlantic Oscillation are investigated here using the cross-wavelet transform. The average cross-wavelet powers and local relative phases are calculated. It is shown that near a centre of action associated with the NAO the changes of total ozone column are maximal and become apparent immediately after the changes in the weather pattern. © 2011 Elsevier Ltd.
