In this paper we present the studies conducted on blood samples taken from Mallards (Anas platyrhynchos). Birds were captured for ringing purposes (n = 43) in two small and two big towns (including highly urbanized areas). For comparison samples of blood from birds shot on fish ponds were used (n = 26). Based on the body mass all sampled individuals can be assessed as being in good condition. Levels of cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), nickel (Ni), lead (Pb) and zinc (Zn) in blood samples were measured with AAS. Concentrations of metals did not differ statistically between sexes and made up a following order: Fe > Zn > Cu > Cr ≈ Ni > Pb > Cd. Mallards from towns revealed lower concentrations of Zn and Cu but higher concentration of Fe. There was no difference in exposition to Pb between birds from towns and fish ponds. © 2013 Elsevier B.V. All rights reserved.

The outcomes of dilatometric, rentgenographic (XRD), microscopic (SEM) as well as dielectric measurements of polycrystalline Ba(Ti1 - xSn x)O3 (BTSx) are described. These measurements were carried out within the range of para-ferroelectric phase transition and also for the high temperature paraelectric phase (from 300 K to 723 K). Within the range, where glass-like anomalies were noticed, the occurrences of electric properties peaks were recorded as well. Their occurrences are interpreted under the assumption of polar regions presence within the paraelectric phase. The size and dynamics of these polar regions influence the dielectric response at given temperatures and frequency of external electric field. Anomalies of dielectric losses and phase angle are pointing out on non-homogeneity and thermal evolution of polar regions. © 2010 Elsevier Ltd and Techna Group S.r.l.

The paper presents current knowledge of ticks occurring in Poland, their medical importance, and a review of recent studies implemented in the Polish research centres on ticks and their significance in the epidemiology of transmissible diseases. In the Polish fauna there are 19 species of ticks (Ixodida) recognized as existing permanently in our country: Argas reflexus, Argas polonicus, Carios vespertilionis, Ixodes trianguliceps, Ixodes arboricola, Ixodes crenulatus, Ixodes hexagonus, Ixodes lividus, Ixodes rugicollis, Ixodes caledonicus, Ixodes frontalis, Ixodes simplex, Ixodes vespertilionis, Ixodes apronophorus, Ixodes persulcatus, Ixodes ricinus, Haemaphysalis punctata, Haemaphysalis concinna, Dermacentor reticulatus. Occasionally, alien species of ticks transferred to the territory of Poland are recorded: Amblyomma sphenodonti, Amblyomma exornatum, Amblyomma flavomaculatum, Amblyomma latum, Amblyomma nuttalli, Amblyomma quadricavum, Amblyomma transversale, Amblyomma varanensis, Amblyomma spp., Dermacentor marginatus, Hyalomma aegyptium, Hyalomma marginatum, Ixodes eldaricus, Ixodes festai, Rhipicephalus rossicus, Rhipicephalus sanguineus. The most common species of the highest medical and veterinary importance in Poland is invariably Ixodes ricinus. The review also sets out information on the risks of tickborne diseases in recreational areas of large cities in Poland, ticks as the cause of occupational diseases and dangerous species of ticks attacking people outside the Polish borders. Selected problems of the biology of ticks, the spread of alien species transferred on hosts and prevention of tick attacks have also been presented. The Polish studies on ticks are a valuable contribution to global research on the Ixodida.

Anti-plane shear of piezoelectric fibrous composites is theoretically investigated. The geometry of composites is described by the 2-dimensional geometry in a section perpendicular to the unidirectional fibers. The previous constructive results obtained for scalar conductivity problems are extended to piezoelectric anti-plane problems. First, the piezoelectric problem is written in the form of the vector-matrix -linear problem in a class of double periodic functions. In particular, application of the zeroth-order solution to the -linear problem yields a vector-matrix extension of the famous Clausius-Mossotti approximation. The vector-matrix problem is decomposed into two scalar -linear problems. This reduction allows us to directly apply all the known exact and approximate analytical results for scalar problems to establish high-order formulae for the effective piezoelectric constants. Special attention is paid to non-overlapping disks embedded in a two-dimensional background. © 2013 The Author(s).

Density functional theory is applied to study the effect of substitutional Fe, Al, and In impurities on the structural, electronic, and magnetic properties of stoichiometric and nonstoichiometric CoO. Ab initio calculated hyperfine interactions at the Fe impurity are used to determine aliovalent states of iron dopant in CoO and Co1-xO systems as well as to characterize the local structure around the impurity. Various Hubbard potentials describing the on-site Coulomb interactions at the Fe impurity are considered, and their influence on the calculated hyperfine parameters and electronic structure of Fe-doped CoO is analyzed. Different vacancy-impurity configurations within the Co-deficient matrix are taken into account to find the site preferences for Fe, Al, and In dopants. The hyperfine parameters at the Fe impurity in Co 1-xO are also investigated as a function of the distance between vacancy and impurity. This study shows that divalent Fe cations are created inside the almost perfect host lattice, while the trivalent Fe cations are stabilized in the system containing cobalt vacancies. Trivalent Co ions are induced in the cobalt sublattice defected by vacancies and impurities. The overall concentration of trivalent cations in Co1-xO is twice as large as the concentration of cation vacancies. Trivalent cations of different ionic radii prefer residing in the second-neighbor sites of a cationic sublattice with respect to the cobalt vacancy. The energy gap of CoO with Fe2+ ions is comparable to that calculated for the defect-free system. The band gap of Co1-xO with Fe3+ and Co3 + ions is reduced due to the acceptor states introduced by both trivalent cations. Band-gap reduction arising from acceptor levels created by Co3+ cations is also observed for Co1-xO defected by nonmagnetic trivalent impurities. The present first-principles studies support and supplement results of several Mössbauer spectroscopy experiments. © 2011 American Physical Society.

Ab initio studies of structural, elastic and electronic properties of the tetragonal perovskite-type PbZr0.5Ti0.5O3 are presented using the pseudo-potential plane wave method within the density functional theory in generalized gradient approximation. The calculated equilibrium lattice parameters remain in a good agreement with the available experimental data. The bulk modulus obtained from the Birch-Murnaghan equation of state is calculated as it B0 = 170 GPa, and the gap energy E g = 2.1-3.5 eV. The some differences between calculated and nominal charges exist for all atoms. The biggest ones are on the Pb ions. They are caused by hybridization of the Pb 6s and O 2p states. The influence of the strain on the averaged over directions Young modulus in the 0.1-0.3% range was studied. © 2013 Elsevier Ltd. All rights reserved.

The European Union has obligated all Members States, to perform a preliminary assessment to identify the catchments at risk of flooding. Usually, hydro-meteorological data and historical information about flooding are used to determine whether a catchment is at risk of flooding or not. Such information is missing for many small Carpathian catchments. Therefore, a method, enabling identification of small catchments more prone to flash flood generation, was proposed. The method focused on physiographic parameters of catchment. Eighty-five catchments where flash floods were well-documented, were described by physiographic parameters. The parameters described dimension, shape, relief, hydrological and geological conditions and land use. Then, the influence of those parameters on flash flood formation process was studied. The results revealed that physiographic parameters of those catchments made them more sensitive to flash flood generation. On the basis of these parameters, types of the Carpathian catchments more prone to flash flood generation were created. The method was tested in south-eastern part of the Polish Carpathians. Catchments resembling the types were identified within a group of 366 catchment located in this area. The results revealed that many flash flood events recorded in the study area, had taken place within catchments identified by use of the method. This fact suggests that the method enable to identify catchments more prone to flash flooding in the geographical space. Therefore, the method may be a valuable tool in the process of flood risk management in the Carpathians.

The distribution of the meadow tick, Dermacentor reticulatus (Fabricius) is divided into two separate areas-Western Europe and Eastern (Russian). The break in distribution of this species falls in Poland, as well as other sites. The populations of D. reticulatus in Poland, which have been confirmed by collecting ticks from vegetation, are located in the north-eastern and western parts of the country, although there are also reports of D. reticulatus occurring on hosts in several parts of Poland which have not been confirmed by collecting ticks from vegetation. Until this research was carried out, the view was that this species does not occur in the western part of Poland in the area between the Vistula and Oder rivers. In the site surveys conducted in the Lubuskie Province (western part of Poland around the city of Zielona Góra, about 55 km from the Polish-German border), during the springtime activity peak for adult stages looking for hosts, seven natural implantations of D. reticulatus were discovered where 208 tick specimens were collected by flagging. These were exclusively adult stages, including 127 females and 81 males. Because of the distance (around 350 km) from the nearest focus in Mazuria in North-eastern Poland, the populations discovered have been named the D. reticulatus "Lubuskie Focus". The research proves for the first time that D. reticulatus occurs in Western Poland. The research indicates that D. reticulatus is the second most important tick in Poland, after Ixodesricinus (L.), which is epidemiologically very important, especially as a parasite on dogs and cattle. The proliferation of the meadow tick in Central Europe is inseparably linked with the expansion of canine babesiosis. © 2011 Springer Science+Business Media B.V.

A mapping f:VnW, where V is a commutative group, W is a linear space, and n<2 is an integer, is called multi-quadratic if it is quadratic in each variable. In this paper, we prove the generalized Hyers-Ulam stability of multi-quadratic mappings in Banach spaces and complete non-Archimedean spaces. © 2011 Elsevier Ltd. All rights reserved.

The project Malopolska Researchers Night will be implemented in the years 2014 and 2015 respectively for the eighth and ninth time. The event has already permanently inscribed in the calendar of Malopolska scientific events, enjoying growing from year to year popular among participants and becoming one of the biggest Nights in Europe. In 2013, this event was attended by over 55 thousand people, while in the first year of the project (2007) the event was attended only by 3.5 thousand people. The event program specified in the application is even richer than before it will take over 1 thousand activities, mainly interactive workshops, presentations, demonstrations and experiments as well as shows with the participation of scientists. It is estimated that 60 thousand people will participate in the events in 2014 and 65 thousand people in 2015. Malopolska Researchers Night is to first of all show participants how interesting is the work of scientists and how fascinating they are people. Through fun, in accessible and understandable way for everybody, we want to show that all around us is the science, and that scientists in their laboratories are working every day to make our life better, easier and more modern. The main motto of the project for the years 2014 and 2015 will be to present the successes of Malopolska scientists working in international scientific-research teams. The event will be held in six cities of the Region: Krakow, Tarnow, Nowy Sacz and Niepolomice and - for the first time in 2014 - also in Skawina and Andrychow. In addition, it is planned the live broadcast from selected locations via event website. The program will be prepared by almost 900 researchers, more than 1 600 students, about 120 research groups from more than 30 partners. Thanks to the extensive promotional campaign the information about the event will reach to nearly 3.5 million people each year.
