Some Sociological, Legislative and Pedagogical Aspects of the Prevalence of Mobbing among Teachers in Primary School (Case Study)
Authors: Goriup Jana , Šoba Vilma Alina , Purgaj Tjaša 
Published: July 2015

Abstract
The paper sets forth the discussion of the occurrence of mobbing in Slovene elementary school. The study is based on empirical facts collected at three different schools. There are some differences between organizations in occurrence, victims’ characteristics, the reasons and consequences of mobbing. The results of the empirical research of the psychosocial conditions in the analysed working places show that more and more teachers as employees are becoming mobbing victims. Mobbing is defined as a very strong social stress factor. Each individual or social group experiences mobbing at work as a conflict situation and communication. An attacked individual as a victim of the conflict is exposed to permanent and long-term attacks by one or more people at work. The intention of these attacks is to oust the individual from the organization or to harm him/her in other ways. A lot of pressure is being imposed on the person and also intimidation, humiliation, molestation or other negative influences appear. Because of the psychic burden the victim usually becomes ill and often leaves the working position. Mobbing can affect the individual in a way that s/he is no longer capable of fitting into any new working environment. The most frequent consequences named by the victims are: stress, insomnia, concentration problems and family problems.
Enhancing Learners’ Interest by Implementing Multiple Intelligence Theory
Authors: Wójcik Katarzyna 
Published: July 2015

Abstract
Learners’ interest is agreed by most of the educators to be significant for effectiveness of teaching and learning process. However postmodern society becomes more and more tranquilized or overactive (depending on the person) because of hundreds of information, pictures and others attacking people’s minds. Therefore gaining students’ attention and then attaching it to the subject becomes more and more difficult. The article makes an attempt to answer the question What is the role of Multiple Intelligence in enhancing learners’ interest level?
Hydrophobic core structure of macromomycin – the apoprotein of the antitumor antibiotic auromomycin – fuzzy oil drop model applied
Authors: Roterman-Konieczna Irena , Banach Mateusz , Konieczny Leszek 
Published: July 2015

Abstract
The fuzzy oil drop model was applied to analyze the structure of macromomycin, the apoprotein of the antitumor antibiotic auromomycin, revealing the differentiation of β-structural fragments present in β-sandwich. The seven-stranded antiparallel β-barrel and two antiparallel β-sheet ribbons represent the highly ordered geometry of the structure. However, participation in hydrophobic core formation appears different. The structure of the complete domain represents the status of the irregular hydrophobic core; however, some β-structural fragments appear to represent the hydrophobicity density distribution accordant with the idealized distribution of hydrophobicity as expected using the fuzzy oil drop model. Four β-structural fragments generating one common layer appear to be unstable in respect to the general structure of the hydrophobic core. This area is expected to be more flexible than other parts of the molecule. The protein binds the ligand – chromophore, two 2-methyl-2,4-pentanediol – in a well-defined cleft. The presence of this cleft makes the general structure of the hydrophobic core irregular (as it may be interpreted using the fuzzy oil drop model). Two short loops generated by two SS bonds fit very well to the general distribution of hydrophobicity density as expected for the model. No information about the potential amyloidogenic character of this protein is given in the literature; however, the specificity of the hydrophobicity distribution profile is found to be highly similar to the one observed in transthyretin (Banach M, Konieczny L, Roterman I. The fuzzy oil drop model, based on hydrophobicity density distribution, generalizes the influence of water environment on protein structure and function. J Theor Biol 2014;359:6–17), suggesting a possible tendency to turn to the amyloid form. A detailed analysis of macromomycin will be given, and a comparable analysis with other proteins of β-sandwich or β-barrel will be presented.
Assortative Outsourcing with Exit
Authors: Bakhtiari Sasan 
Published: July 2015

AbstractA general framework is presented that incorporates dynamics and heterogeneity among both upstream suppliers and downstream producers to mimic the exit strategy of Hirschman (1970) in building vertical relations. An assortative matching develops between producers and suppliers based on their level of efficiency, which leads to an increase in the aggregate industrial productivity but also makes the distribution of firms more dispersed. Further experiments suggest that the nature of outsourcing relations is impacted in certain ways by business cycles and technological advancements.
Living on the edge: studies on ecology of plant species and populations at the limits of their geographic range. Tribute to Professor Janusz B. Faliński (1934-2004)
Authors: Czarnecka Bożenna 
Published: July 2015

Abstract
Abies alba and Senecio rivularis - two of 44 mountain species reported from the Roztocze Highlands, SE Poland were objects of the study. Both species reach the north-eastern limits of their occurrence in this region. In case of Abies alba, the extent of its habitat niche and possibility of adaptation to alternative niches at the range limits were investigated in two areas of the Roztocze Highlands - the Roztocze National Park (RNP) and gorge sections of four river valleys (RV) of a mountainous character. In both landscapes, fir prefers mineral soils that are too leachy for deciduous species and even for spruce. In the RV sites, fir seems to have a much broader ecological scale and often colonizes organic soils with wet mixed coniferous forests with spruce, ash-alder, and bog alder forests.
The studies on Senecio rivularis are an example of long-term ecological studies at the population level, conducted in the RNP since 1987, e.g., in terms of changes in the size structure of individuals compared to the changes in the surface area covered by this population. A nearly 3-fold increase in the area inhabited by the population was accompanied by changes in the spatial organisation of the population and individual size structure dynamics, which reflects the intensification of intra- and interspecific competition, and indicates condition changes in the population area.
The effect of habitat conditions on the abundance of populations and selected individual and floral traits of Impatiens glandulifera Royle
Authors: Kostrakiewicz-Gierałt Kinga 
Published: July 2015

Abstract
The effect of site conditions on the abundance of populations of I. glandulifera, selected individual features (height and width of stems, number of whorls and side branches, flower production), and floral traits (total length of flowers, length and width of lower sepal, spur length) were investigated in years 2013-14. Observations were conducted on fallow land, at roadsides, along riverbanks and edges of a riparian forest as well as in a willow thicket and a riparian forest inside located in the Vistula River valley in southern Poland. In these stands, taken successively, light availability gradually diminished, while plant canopy height and soil moisture increased. The low abundance of the population on the fallow land may have been caused by low soil humidity triggering seedling mortality, whereas the low abundance in the interior of the riparian forest may have been due to seasonal water stagnation hampering the development of offspring. The increasing values of individual traits from the fallow land to riparian forest edge might be linked to growing lateral shade, whereas the much lower values in the willow thicket and forest interior might be caused by full shade. Individuals growing on the fallow land, at roadsides, and along riverbanksproduced flowers with small total lengths and large lower sepals and spurs, whereas individuals occurring in willow thickets and riparian forests showed opposite tendency. The considerable stem dimensions and substantial production of large flowers may augment chances for successful resource capture and pollinator visits in open sites, while the reduced size of individuals and moderate production of small flowers may be sufficient for the maintenance of populations in closed habitats
Characterization of morphological traits and RAPD polymorphism in selected forms of Kentucky bluegrass (Poa pratensis L.)
Authors: Szenejko Magdalena , Rogalski Maciej 
Published: July 2015

Abstract
Measurements were taken of seven morphological characteristics of various forms of Poa pratensis, including ecotypes (12), cultivars (4), and breeding lines (2). Statistically significant differences relating to the average number and length of vegetative shoots and the leaf width of the forms studied were determined using Tukey’s HSD test. Evaluation of genetic polymorphism was carried out using the RAPD-PCR method. 18 primers were used for molecular analysis and 473 amplification products were obtained, in which high levels of polymorphism (84.2%) and specificity (63) were discovered. The mean value of Dice’s coefficient, the genetic similarity indicator, was about 0.7. These results indicate a significant genetic similarity between most of the forms of Poa pratensis studied. A correlation was also observed between genetic variation and phenotypic diversity of the studied forms of Poa pratensis. Convergence was found to occur between phenotype and genetic similarity among the forms. Only the dos01 468 ecotype showed discrepancies in the assessment of phenotypic and genomic variability.

AbstractAlthough therapeutic drug monitoring (TDM) for antibiotics in critically ill patients is recommended by expert panels, no commercial tests are available for most antibiotics. Therefore, we previously developed a multi-analyte method for the quantification of piperacillin, tazobactam, cefepime, meropenem, ciprofloxacin and linezolid in serum. However, limited stability data were available, and the relevant studies did not address the coefficients of variation of the methods applied, which may be important for verifying the storage dependency of the observed effects. Here we aimed to evaluate the storage effects of antibiotics by applying a novel evaluation protocol.Serum-based test samples were aliquoted and stored at room temperature, 4 °C, −20 °C or −80 °C for up to 180 days. Using an innovative evaluation protocol (considering the coefficient of variation, p-value, and criterion of monotony of observed changes), we assessed whether relevant changes (defined as ≥15% in comparison with baseline) were storage dependent (defined as substantial changes).Storage at −80 °C for up to 180 days did not lead to substantial changes for any analyte. In contrast, storage at −20 °C induced substantial decreases after ≥7 days for piperacillin, tazobactam, cefepime and meropenem; after 90 days at −20 °C, only ≤23% of the initial concentrations were found for these parameters. No substantial changes were observed for linezolid and ciprofloxacin at any storage condition. All of the observed substantial changes were monotonic decreases.We recommend a storage temperature of −80 °C for β-lactam antibiotics. The applied evaluation protocol yielded conclusive results and may be generally useful for stability studies.

Published: July 2015

AbstractThe present study investigated the impact of the driving force (Δp) on the transport properties. All the experiments and calculations were performed for air-gap membrane distillation (AGMD). In the course of the experiments, it was found that an identical value of Δp could be attained by applying different values of feed and permeate temperatures. It was highlighted that constant values of water fluxes could be achieved using the constant driving force created by different temperatures. Moreover, the relation between ln(J

Abstract
Effects of mixing on the course of fast chemical reactions are relatively well understood, especially in homogeneous systems. This enables to design and operate chemical reactors with the goal to achieve a high yield of a desired product and use systems of complex reactions as a chemical probe (chemical test reactions) to identify progress of mixing and quality of mixture. Recently, a number of studies have focused on the application of chemical test reactions to identify energy efficiency of mixing, being a convenient way of comparing mixers and reactors in terms of their mixing efficiency. This review offers a presentation of chemical test reactions available in the literature and methods of applications of test reactions to identify the energy efficiency of mixing. Also methods to assess the extent of micromixing by measuring product distribution or segregation index, and to determine the time constant for mixing are presented for single phase homogeneous systems and two-phase liquid-liquid systems.
Comparison of Large Eddy Simulations and κ-ε Modelling of Fluid Velocity and Tracer Concentration in Impinging Jet Mixers
Authors: Wojtas Krzysztof , Orciuch Wojciech , Makowski Łukasz 
Published: July 2015

Abstract
Simulations of turbulent mixing in two types of jet mixers were carried out using two CFD models, large eddy simulation and κ-ε model. Modelling approaches were compared with experimental data obtained by the application of particle image velocimetry and planar laser-induced fluorescence methods. Measured local microstructures of fluid velocity and inert tracer concentration can be used for direct validation of numerical simulations. Presented results show that for higher tested values of jet Reynolds number both models are in good agreement with the experiments. Differences between models were observed for lower Reynolds numbers when the effects of large scale inhomogeneity are important.
Hurry or Wait – The Pros and Cons of Going Fast or Slow on Climate Change
Authors: Denny Eleanor , Weiss Jurgen 
Published: July 2015

Abstract
Climate change risk will likely force the de-carbonization of our electricity sector and thus involve massive investments in long-lived assets using many new and emerging technologies. Since technological progress (independent or dependent on deployment) will likely lower the future cost of those technologies, investing early and rapidly forecloses saving money by installing those technologies at a lower cost later. There are thus benefits to waiting until the costs of renewables fall further. However, there are also costs to waiting. First, given the longevity of greenhouse gases in the atmosphere, cumulative emissions matter and lowering greenhouse gas emissions earlier is beneficial. Second, there is significant uncertainty not only over the rate of change of the cost of low carbon technologies, but also over the cost of greenhouse gas emissions. The costs of waiting are complex in that the distributions themselves are unknown (and quite possibly have “fat” tails). There may also be complex timing issues such as points of no return in terms of global greenhouse gas concentrations, beyond which the costs of adapting to climate change effects become essentially infinite. Hurrying can therefore be considered an insurance policy against the unknown but perhaps increasing risk of catastrophic damage.

Abstract
Reaction of 2-hydrazinoquinazolin-4(3H)-ones with acetylacetone results in the formation of 1-methyl[1,2,4]triazolo[4,3-a]quinazolin-5(4H)-ones instead of 2-(3,5-dimethyl-1H-pyrazol-1-yl)quinazolin-4(3H)-ones. Under similar conditions, the 7-hydrazinocarbonyl group in quinazolin-4(3H)-one moiety is transformed into a pyrazole derivative, which can be replaced by amine with the amide formation.

Published: July 2015

AbstractFine tuning of c-MYC expression is critical for its action and is achieved by several regulatory mechanisms. The contribution of c-mycmRNA regulatory sequences on its translational control has been investigated individually. However, putative interactions have not been addressed so far. The effect of these interactions upon the translatability of monocistronic and bicistronic chimaeric mRNAs, carrying combinations of the c-mycmRNA 5′-untranlated region (UTR), 3′-UTR, and coding region instability element (CRD) was investigated on this study. The presence of the 5′-UTR induced an increase in translatability of 50%. The presence of the CRD element, when in frame, reduced translatability by approximately 50%, regardless of the expression levels of the wild type CRD- binding protein (CRD-BP/IMP1). Conversely, overexpression of a mutated CRD-BP/IMP1 (Y396F) further impeded translation of the chimaeric mRNAs carrying its cognate sequences. The presence of the c-myc3′-UTR increased translatability by approximately 300% affecting both cap and c-mycinternal ribosome entry site (IRES) mediated translation. In addition, 3′-UTR rescued the cap mediated translation in the presence of the polyadenylation inhibitor cordycepin. Furthermore, the 3′-UTR rescued cap mediated translation under metabolic stress conditions and this was enhanced in the absence of a long poly (A) tail.

Published: July 2015

AbstractEffect of cryogenic hard turning parameters (cutting speed, feed rate, and depth of cut) on surface roughness (Ra) and micro-hardness (µH) that constitute surface integrity (SI) of the machined surface of alloy steel AISI 52100 is investigated. Multilayer hard surface coated (TiN/TiCN/Al2O3/TiN) insert on CNC lathe is used for turning under different cutting parameters settings. RSM based Central composite design (CCD) of experiment is used to collect data for Ra and µH. Validity of assumptions related to the collected data is checked through several diagnostic tests. The analysis of variance (ANOVA) is used to determine main and interaction effects. Relationship between the variables is established using quadratic regression model. Both Ra and µH are influenced principally by the cutting speed and the feed rate. Model equations are found to predict accurate values of Ra and µH. Finally, desirability function approach for multiple response optimization is used to produce optimum SI.
On the different formalisms for the transport equations of thermoelectricity: A review
Authors: Manzanares José A. , Jokinen Miikka , Cervera Javier 
Published: July 2015

Abstract
Researchers in thermoelectricity with backgrounds in non-equilibrium
thermodynamics, thermoelectric engineering or condensed-matter physics tend
to use different choices of flux densities and generalized forces. These
choices are seldom justified from either the dissipation function or the
entropy production rate. Because thermoelectric phenomena are a primary
focus in several emerging fields, particularly in recent energy-oriented
developments, a review of the different formalisms employed is judged
timely. A systematic classification of the transport equations is presented
here. The requirements on valid transport equations imposed by the
invariance of the entropy production are clearly explained. The effective
Peltier and Seebeck coefficients, and the thermal conductivity,
corresponding to the different choices of flux densities and generalized
forces, are identified. Emphasis is made on illustrating the compatibility of
apparently disparate formalisms. The advantages and drawbacks of these
formalisms are discussed, especially from the point of view of the
experimental determination of their thermoelectric coefficients.

AbstractTo investigate whether there is a change in bone turnover-related biochemical markers and bone mineral density of children with constitutional delay of growth and puberty (CDGP) in the prepubertal period.We measured serum calcium, phosphorus, alkaline phosphatase, parathormone, 25-OH vitamin D, osteocalcin, osteoprotogerin and urinary deoxypyridinoline levels (D-pyd), and bone mineral density (BMD) in 31 prepubertal boys with CDGP. These children were compared with 22 prepubertal boys with familial short stature (FSS) and 27 normal prepubertal boys.Urinary D-pyd was significantly high in CDGP group as compared to control group (p=0.010). Volumetric BMD did not significantly differ between CDGP, FSS, and control groups (p=0.450). Volumetric BMD and urinary D-pyd levels of FSS and control groups were similar. Mean or median levels of calcium, phosphorus, alkaline phosphatase, parathormone, and osteoprotegerin did not significantly differ between CDGP, FSS, and control groups.Our data suggest that prepubertal boys with CDPG have normal bone turnover. However, their significantly higher urinary D-pyd levels relative to those of FSS and control groups might be an indicator of later development of osteoporosis. Therefore, long-term follow-up studies monitoring bone mineral status of prepubertal boys with CDPG from prepuberty to adulthood are needed to better understand bone metabolism of these patients.
