Abstract
The paper presents results of the research project Social and Moral Aspects of Economic and Civic Life of Rural Youth, which was supported by the Ministry of Education, Science, Research and Sport of the Slovak Republic, through the Slovak Youth Institute under the specific scheme Support and Development of Research in the Field of Youth Policy. With the focus on the problems of contemporary life of rural youth, it emphasizes socio-economic and civic-politic dimension of its life. It maps different aspects as well as the influence of particular factors and institutions that affect behaviour and choices of young people in rural areas. The research methodology was based on qualitative approach using observation and personal semi-standardized interview method during the field survey. Interviews were conducted with 106 young people aged 18-30 from 39 rural communities localized in different parts of Slovakia in 2014. Besides introduction to the context, the authors describe methodological framework and the sampling procedure, the key research goals and questions, and basic research findings. They conclude that rural youth needs to be given certain stimulus and support in all possible areas of existence and participation, as well as tolerance and acceptance of their new ideas and thoughts.
Potential of Miscanthus × Giganteus for Heavy Metals Removing from Industrial Deposol
Authors: Dražić Gordana , Milovanović Jelena , Stefanović Slobodan , Petrić Ivana 
Published: May 2018

Abstract
Agro-energy crop, Miscanthus × giganteus should be produced on marginal land in order to avoid land suitable for food production. Production of electricity in thermal power plants occupies large land areas by depositing tailings from surface mines, and depositing ash and slag. During the first year of Miscanthus × giganteus growing in containers, the concentration of heavy metals: As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn and Fe was monitored in underground and aboveground plant parts. The substrate was overburden from open pit coal mine RB Kolubara and ash from TPP Nikola Tesla B. Significant differences were found between the substrate and the investigated elements, but in all cases the accumulated heavy metals almost completely remained stable in underground organs of plant. It can be concluded that biomass of Miscanthus × giganteus could be used as energy source if it is grown on a soil moderately contaminated by heavy metals.
Analysis of Selected Environmental Indicators in the Cultivation System of Energy Crops
Authors: Šoltysová Božena Š , Danilovič Martin 
Published: May 2018

Abstract
The changes of selected chemical parameters were observed in Gleyic Fluvisols. The field experiment was established as a twofactor experiment with four energy crops (Arundo donax L., Miscanthus × giganteus, Elymus elongatus Gaertner, Sida hermafrodita) and two variants of fertilization (nitrogen fertilization in rate 60 kg ha-1, without nitrogen fertilization). Soil samples were taken from the depth of 0 to 0.3 m at the beginning of the experiment in the autumn 2012 and at the end of reference period in the autumn 2015. Land management conversion from market crops to perennial energy crops cultivation has influenced changes of selected soil chemical parameters. The contents of soil organic carbon were affected by cultivated energy crops differently. It was found out that Arundo increased the organic carbon content and Miscanthus, Elymus and Sida decreased its content. At the same time, the same impact of the crops on content of available phosphorus and potassium and soil reaction was found. It was recorded that each cultivated crop decreased the soil reaction and available phosphorus content and increased the content of available potassium.
Determination of Production Efficiency of Crop Mixtures: the Relevance of the Agronomic Efficiency Method
Authors: Odion Ehiabhi Cyril , Ahmadu Idris Salihu , Aminu Ahmed Rufai , Luka Grace Lamba , Isah Shero Abdulazeaz , Arunah Uthman Lucky 
Published: May 2018

Abstract
The paper looks at estimation of the agronomic efficiency (AE) for various crop mixtures at varying levels of fertility management. To evaluate the concept, three trials using different cropping patterns and fertility rates were reviewed by calculating and comparing the relative yield and agronomic efficiency of the main crop. AE was higher in the mixtures compared to the sole crop in all the trials, and in the mixtures while efficiency between the control and the fertility levels employed were high, those between the fertility levels were not as high and increased at a reducing rate, sometimes tending to be constant. These responses gave rise to situations similar to a quadratic response and could therefore permit for optimum fertility levels for crop mixtures to be predicted. This therefore means that sustainable intensification is possible under small scale production systems as increase in efficiency was higher at lower fertilizer rates compared to the higher rates. Assessment of AE for crop mixture could also result in staggered recommended production practices, thus discouraging the excessive use of fertilizers – chemical or organic – and cut cost of production, reduce the pollution of the environment with its attendant consequences while production costs could be within reach of the small scale farmers. Small scale family farmers seeking alternative methods of soil fertility management could be encouraged to undertake the clipping/thinning management of companion leguminous crops as such measures could enhance their productivity as the estimation of AE has shown in these investigations. The practice of either clipping or thinning of the leguminous companion crop is similar or close to current production practices employed by these farmers and therefore should not be difficult to adapt and adopt.

Authors: Măgdoiu Alex , Oprean Constantin 
Published: May 2018

Abstract
This paper will present the development of the poka yoke systems, which were initially created and implemented just for the automotive industry, also to other domains. For some fields like medicine, constructions or software development there are already articles available on the benefits brought by poka yoke systems’ implementation. Besides these domains the article will contribute to the recognition of poka yoke systems in fields where, although error proofing systems are used, no link to the poka yoke method was made by the authors, creators and users
Regularity, positivity and asymptotic vanishing of solutions of a φ-Laplacian
Authors: Arriagada Waldo , Huentutripay Jorge 
Published: May 2018

Abstract
In this note we prove that solutions of a φ-Laplacian operator on the entire space ℝN are locally regular (Hölder continuous), positive and vanish at infinity. Mild restrictions are imposed on the right-hand side of the equation. For example, we assume a Lieberman-like condition but the hypothesis of differentiability is dropped. This is in striking contrast with the classical case.
Comparison Between Measurements and WRF Numerical Simulation of Global Solar Irradiation in Romania
Authors: Isvoranu Dragos , Badescu Viorel 
Published: May 2018

Abstract
The paper presents a comparative analysis between the surface global irradiation measured for Romania and the predicted irradiation obtained by numerical simulation. The measured data came from the Romanian National meteorological Administration. Based on a preliminary analysis that took into account several criteria among which, performance, cost, popularity and meteorological and satellite data accessibility we concluded that a combination GFS-WRF(NMM) or GFS-WRF(ARW) is most suitable for short term global solar irradiation forecasting in order to assess the performance of the photovoltaic power stations (Badescu and Dumitrescu, 2012, [1], Martin et al., 2011, [2]).
Regional Courts as Judicial Brakes?
Authors: Metcalf Katrin Nyman , Papageorgiou Ioannis F. 
Published: May 2018

AbstractThe article examines how regional integration courts can act as judicial brakes, at a time when “constitutional coups” – leaders staying in power past constitutional time limits or other forms of actions against the spirit if not always the letter of the constitution – are alarmingly common. The article discusses how regional courts can be used to modify or protect national rule of law and the constitutional order from the outside (i.e. from the regional integration aspect) and the extent to which this can be valid particularly to promote a uniform interpretation and application of human rights. Although this trend is visible in Europe, it is more striking, because less expected, on other continents, in particular Africa and the Americas, where the developments take place in less than perfect democratic environments. The article contains evidence from cases dealt with in the various regional courts, supporting that a system of political and judicial oversight, especially in regions with weak or fragile democratic systems, can be a useful addition to national judicial or other mechanisms of protection of rule of law and control of the executive. Action by regional courts helps defeat perceptions of majoritarian politics, which in many countries allow for the winner to take all. Under a system of regional oversight, states become aware of the limits they themselves have set and citizens become aware of their possibilities to challenge political power.

Abstract
Desmid algae from three families, 17 genera were registered in the investigated habitats of the Aukštumala Telmological Reserve. A total of 56 desmid algae taxa (50 species and six varieties) were recorded. Species of the Desmidiaceae family dominated. They comprised 73% of all desmid species found. Mesotaniaceae and Closteriaceae comprised 16% and 11%, respectively. The highest diversity was discovered in the samples collected on the margins of the pools (45 species) and in the wet hollows with Sphagnum cover (35 species). Most species were found in the samples collected in August (36 species) or in March and June (25 and 28 species, respectively). The seasonal and spatial distribution of desmid algae species was observed.
Particle Swarm Optimization Algorithm with Adaptive Chaos Perturbation
Authors: Yong Dong , Chuansheng Wu , Haimin Guo 
Published: May 2018

Abstract
Most of the existing chaotic particle swarm optimization algorithms use logistic chaotic mapping. However, the chaotic sequence which is generated by the logistic chaotic mapping is not uniform enough. As a solution to this defect, this paper introduces the Anderson chaotic mapping to the chaotic particle swarm optimization, using it to initialize the position and velocity of the particle swarm. It self-adaptively controls the portion of particles to undergo chaos update through a change of the fitness variance. The numerical simulation results show that the convergence and global searching capability of the modified algorithm have been improved with the introduction of this mapping and it can efficiently avoid premature convergence.
Mathematical models of the Earth’s density structure and their applications in gravimetric forward modeling
Authors: Tenzer Robert 
Published: May 2018

Abstract
A generalized mathematical model of the Earth’s density structure is presented in this study. This model is defined based on applying the spectral expressions for a 3-D density distribution within the arbitrary volumetric mass layers. The 3-D density model is then converted into a form which describes the Earth’s density structure by means of the density-contrast interfaces between the volumetric mass layers while additional correction terms are applied to account for radial density changes. The applied numerical schemes utilize methods for a spherical harmonic analysis and synthesis of the global density structure models. The developed the Earth’s density models are then defined in terms of the spherical density and density-contrast functions. We also demonstrate how these Earth’s density models can be applied in the gravimetric forward modeling and discuss some practical aspects of representing mathematically density structures within particular components of the Earth’s interior.

Abstract
Field revision of current distribution of mountain hawkweeds (Hieracium s. str.) in the Hrubý Jeseník Mts was undertaken. Hieracium atratum, H. chlorocephalum, H. engleri, H. grabowskianum and H. plumbeum, whose last occurrence was documented many decades or even a century ago, were rediscovered. H. plumbeum was even found in new localities. The occurrence of H. alpinum, H. bifidum, H. chrysostyloides, H. inuloides, H. nigritum, H. prenanthoides, H. silesiacum, H. stygium and H. villosum was ascertained at many of their historical localities and a few new localities were found too. A neophyte species H. mixtum was discovered. Hieracium moravicum was not found. Accurate locality description and population size are provided for each finding. Herbarium revision and excerption of crucial literature were performed to provide historical distribution. Distributional changes as well as threatening and beneficial factors influencing Hieracium species in the Hrubý Jeseník Mts are discussed.

Clinical Case of Aplastic Crisis Associated with Extramedullary Hematopoiesis in an Adult With Hereditary Spherocytosis and Parvovirus B19 Infection
Authors: Jercan Andreea , Gina Rusu Munteanu , Dobrea Camelia , Coriu Daniel , Tatic Aurelia 
Published: May 2018

Abstract
Hereditary spherocytosis is an inherited hemolytic anemia due to red cell membrane defects, characterised by chronic hemolysis with different severity degrees, splenomegaly and microspherocytosis on the peripheral blood film.
Among the possible complications in these patients are aplastic crisis and extramedullary hematopoiesis.
In this article we present the case of a 42 years old man with hereditary spherocytosis diagnosed during childhood (average haemoglobin (Hb) value of 11-12 g/dl), which presented with worsening anemia, fever, chills, bone and muscle pain. The evolution was with accentuation of anemia (Hb 4.2 g/dl), decease of reticulocyte number (Ret 0,8%) and bilirubin (indirect bilirubin 2.7 g/dl). ParvovirusB19 DNA was 100.000.000 copies/ml. A computer tomography (CT)scan was performed and showed extramedullary hematopoiesis areas situated paravertebraly in the inferior thorax and hepatosplenomegaly. The infectious episode was self-limited and improved with substitution treatment.
Actual Causes and Free Will
Authors: Sartorio Carolina 
Published: May 2018

AbstractIn this paper I reexamine the debate between two contrasting conceptions of free will: the classical model, which understands freedom in terms of alternative possibilities, and a more recent family of views that focus only on actual causes, and that were inspired by Frankfurt’s famous attack on the principle of alternative possibilities. I offer a novel argument in support of the actual-causes model, one that bypasses the popular debate about Frankfurt-style cases.
Diversity in the standard of living among populations in European post-comunist countries
Authors: Michalski Tomasz 
Published: May 2018

Abstract
The aim of this study was to present the general situation of populations of European post-communist countries 25 years after the collapse of communism in Europe. The study consists of two parts. The first one briefly discusses the processes that led to a significant diversification in the social, economic and political situations of the populations of the studied countries. In the second part the diversity of this situation is shown (using: the Legatum Prosperity Index, the Social Progress Index, and the Human Development Index). It was found that the best situations exist in the countries which quickly and effectively implemented reforms, and whether they were independent states, or parts of larger states, under communism is of secondary importance. It is symptomatic that these are countries situated in the north-western part of the area under consideration, which corresponds to the current situation in the EU-15, where the countries located in the south (the so-called PIGS) have poor economic and partly social situations than those in the north. Furthermore, it was found that the situation with the population of Russia is worse than in many countries which were previously under the occupation of the USSR or were dependent on the authorities in Moscow.
Anthropogenic causes of wetland loss and degradation in the lower Kłodnica valley (southern Poland)
Authors: Wójcicki Krzysztof J. , Woskowicz-Ślęzak Beata 
Published: May 2018

Abstract
Loss and degradation of wetlands is now one of the most important environmental issues on a global scale. Previous research based on analyses of cartographic materials allow for quantification of changes in wetland area in recent centuries. The results of lithological research of peat cores, reported in this publication, have established that the processes of anthropogenic loss of wetlands can be much older and in the Kłodnica valley were initiated in the first millennium BC. As a result of increased mineral sedimentation accompanying soil erosion some peatlands have been fossilized whilst the area of others has been reduced. In total, the surface area of peat-forming wetlands in the bottom of the Kłodnica valley decreased by over 60% between the time of the Lusatian Culture settlement and the Middle Ages. Post-peatland habitats are recently used for agricultural or colonized by non-peat forming vegetation. These processes have played a more important role in the degradation of peatland ecosystems than the direct human impact in historic times. Changes in hydrographic networks, land drainage and regulation of water levels in rivers and canals in the last century have contributed to further reducing the wetland areas by almost 50% compared to the 1880s. These processes, however, have mainly affected ephemeral non-peat forming wetlands.
Short-term forecasting of the chloride content in the mineral waters of the Ustroń Health Resort using SARIMA and Holt-Winters models

Published: May 2018

Abstract
The Ustroń S.A. Health Resort (southern Poland) uses iodide-bromide mineral waters taken from Middle and Upper Devonian limestones and dolomites with a mineralisation range of 110-130 g/dm3 for curative purposes. Two boreholes - U-3 and U3-A drilled in the early 1970s were exploited. The aim of this paper is to estimate changes in mineral water quality of the Ustroń Health Resort by taking into consideration chloride content in the water from the U-3 borehole. The data has included the results of monthly analyses of chlorides from 2005 to 2015 during the tests carried out by the Mining Department of the Health Resort. The triple exponential smoothing (ETS) function and the Seasonal Autoregressive Integrated Moving Average (SARIMA) method of modelling time series were used for the calculations. The ability to properly forecast mineral water quality can result in a good status of the exploitation borehole and a limited number of failures in the exploitation system. Because of the good management of health resorts, it is possible to acquire more satisfied customers. The main goal of the article involves the real-time forecast accuracy, obtained results show that the proposed methods are effective for such situations. Presented methods made it possible to obtain a 24-month point and interval forecast. The results of these analyses indicate that the chloride content is forecast to be in the range of 72 to 83 g/l from 2015 to 2017. While comparing the two methods of analysis, a narrower range of forecast values and, therefore, greater accuracy were obtained for the ETS function. The good performance of the ETS model highlights its utility compared with complicated physically based numerical models.
Humour in Peer Interaction in the L2 Classroom
Authors: Leslie Carolyn 
Published: May 2018

Abstract
Research in the study of affect in L2 learning acknowledges that attention to the social dimension can ‘improve language teaching and learning’ and that negative emotions such as anxiety, fear, stress, anger or depression may compromise our learning potential, whereas positive emotions such as self-esteem and empathy can ease the language learning process (Arnold and Brown 1). For the majority of learners, the classroom environment should be a place which encourages interaction and minimises negative emotions such as anxiety, which could interfere with such interaction. This study seeks to describe episodes of humour during peer oral interaction which may help generate a positive social dimension amongst learners.
