Published: May 2018

Abstract
We have investigated the samples of thermally treated oxyfluoride glass ceramics 50SiO2-25LiO2-20YF3-3ErF3-2YbF2 by means of electron paramagnetic resonance (EPR) techniques. After irradiation of the samples with X-rays, in the EPR spectra a hyperfine structure characteristic of F-centres could be observed in different fluoride crystals. The structure of F-centre in the oxyfluoride glass ceramics containing LiYF4 crystallites is discussed.

Abstract
Radiotelescope RT-32 is a fully steerable 32-m parabolic antenna located at Irbene and belonging to Ventspils International Radio Astronomy Centre (VIRAC). Currently, the work on upgrading and repair of its receiving hardware and data acquisition systems is of high priority for the VIRAC.
One of the main scientific objectives for the VIRAC Radioastronomical observatory is VLBI (very long baseline interferometry) observations in centimetre wavelengths in collaboration with world VLBI networks, such as European VLBI network (EVN), Low Frequency VLBI network (LFVN), and others.
During the last years the room in the secondary focus of telescope was reconstructed, and several new receivers were installed. Currently, RT-32 observations are carried out in four different bands: 92 cm, 18 cm, 6 cm, and 2.5 cm. First three of them are already successfully employed in diversified VLBI experiments. The receiver on 2.5 cm band has only one linear polarized chain and is used mainly for the methanol maser single dish observations.
The apparatus system of RT-32 is equipped with two independent VLBI data acquisition systems: TN-16, and DBBC in combination with MK5b. Both systems are employed in interferometric observations depending on the purpose of experiment and the enabled radiotelescopes.
The current status of RT-32, the availability of its receiving and data acquisition units for VLBI observations and the previous VLBI sessions are discussed.
Perceptual global processing and hierarchically organized affordances – the lack of interaction between vision-for-perception and vision-for-action.
Authors: Styrkowiec Piotr , Nęcka Edward 
Published: May 2018

Abstract

In visual information processing, two kinds of vision are distinguished: vision-for-perception related to the
conscious identifi cation of objects, and vision-for-action that deals with visual control of movements. Neuroscience
suggests that these two functions are performed by two separate brain neural systems - the ventral and dorsal pathways
(Milner and Goodale, 1995). Two experiments using behavioural measures were conducted with the objective of exploring
any potential interaction between these two functions of vision. The aim was to combine in one task methods allowing
for the simultaneous capture of both perceptual global processing and affordance extraction and to check whether they
infi uence each other. This aim was achieved by employing the paradigms of Navon (1977) and Tucker and Ellis (1998).
A compound fi gure was created made up of objects with handles that might or might not have orientation congruent
between levels. The results revealed that while the affordance effect occurred every time, the Navon effect appeared only
when subjects focused their attention on object elements responsible for inconsistence within compound fi gure. Most
importantly, even when these two effects occurred at once, they had no effect on each other. Results from the study failed
to confi rm the hypothesis about interaction and gives support to the view that vision-for-perception and vision-for-action
tend to act as separate systems.
Interpreters of the Constitution: The Problem of Typology
Authors: Mesonis Gediminas 
Published: May 2018

ABSTRACT
The significance of the most important legal act-the Constitution-to the social medium is evident. This constituent act of the nation determines the legal, political, moral and social life of the social medium. Therefore, it should come as no surprise that the Constitution-the content of this constituent act-is the object of everybody’s attention. The Constitution is interpreted by lawyers, public leaders, state institutions, scholars and individual persons. The article analyses the wide-ranging subjects interpreting the Constitution and presents the types of its interpreters. The three most prominent groups of such subjects can be distinguished as: (i) institutions of constitutional justice, (ii) the scholarly doctrine, and (iii) other subjects. The article discusses the legal, scientific and social value of interpretations of the Constitution formulated by these interpreters. It is held that the most meaningful thing in this typology is distinguishing the interpretations according to the factor of their legal effects. The differing scientific, legal and social value of the interpretations does not deny the factor of the significance of their existence. It is recognised that a large number of interpretations of the content of the Constitution come from an immanently related state of discussions taking place in a state under the rule of law and democratic society.
Pro Bono Work vs. Legal Aid: Approaches to Ensuring Access to Justice and the Social Responsibility of the Attorney
Authors: Gruodytė Edita , Kirchner Stefan 
Published: May 2018

ABSTRACT
In many jurisdictions middle- and low-income individuals obtain only a relatively modest share of lawyers’ services. In a society ruled by law, every person should be able to expect key principles of justice to apply. Among the most important dimensions of a right to a fair trial is the right to equal access to an attorney. After all, the attorney is not merely a commercial actor but also represents the legal system. Access to an attorney is a key step in providing justice in practice. Many states have developed programs of legal aid which aim at providing those who are in need of legal assistance but cannot afford to pay for legal services with a way to receive legal services. Scientific literature distinguishes various forms and instruments of legal aid: the court appointment of lawyers, free or low cost legal aid provided by public agencies and charitable and fraternal organizations, sometimes mixed with legal expenses insurance, contingency fee and the free services of lawyers who are serving probono publico. From the perspective of practicing attorneys, this article presents and compares existing systems of legal assistance in Lithuania and Germany, and their availability and effectiveness, in order to answer the question whether the social responsibility of attorneys and access to justice is obtained.

Habitat characteristics assessmen of the wetlands with breeding Ferruginous Duck Aythya nyroca and Pochard A. ferina in Bulgaria / Ocena habitatnih značilnosti mokrišč z gnezdečimi kostanjevkami Aythya nyroca in sivkami A. ferina v Bolgariji
Authors: Petkov Nikolai 
Published: May 2018

Abstract
The Ferruginous Duck Aythya nyroca and Pochard A. ferina are both regular breeders in Bulgaria. In the 19th and early 20th centuries, the Ferruginous Duck was a widely distributed and abundant breeding species in Bulgaria, while Pochard was first confirmed to breed in the country only in the 1950s. Breeding habitat characteristics of Ferruginous Duck and Pochard were assessed in 2002 during a national census of the former species in 30 and 23 wetlands, respectively, where the species were present. Preferred habitat characteristics were determined based on vegetation cover, water depth, and the presence of mosaic vegetation, bank side vegetation, floating vegetation, shallow or steep banks, shallow mudflats, shallow vegetated areas and woodland along the banks. In 2002, the Ferruginous Duck population in Bulgaria was restricted more to artificial wetlands, like fishponds and micro-reservoirs, while Pochard preferred more natural wetlands, predominantly natural marshes. The altitude of wetlands with Ferruginous Ducks varied markedly, with breeding recorded up to 880 m a.s.l., while Pochard bred at lower altitudes, mostly below 300 m a.s.l. Analysis revealed that Ferruginous Ducks preferred well-vegetated, comparatively shallow wetlands with well-structured mosaic vegetation and a diversity of microhabitats, like shallow mudflats and floating vegetation. The Pochard was found to be more of a generalist in wetland selection, significantly correlated with fewer wetland parameters, and showed preference only for larger, open-water bodies. These results could help explain and give some insight into the reasons for the differences in range size, numbers and distribution of the two species and their respective conservation status in Europe and worldwide. The Pochard, whilst close to the limits of the breeding range in Bulgaria, expands its range in Europe, occupying a variety of wetlands and thus having a favourable status. The Ferruginous Duck is more of a habitat specialist, which limits its distribution and makes it more susceptible to habitat changes. These habitat preferences and the deterioration of the wetland habitats in many parts of its range could probably explain the Ferruginous Duck decreasing population and shrinking breeding range, and thus its current unfavourable conservation status.
Rethinking the Connection Between Creative Clusters and City Branding: the Cultural Axis of Piraeus Street in Athens
Authors: Karachalis Nicholas , Deffner Alex 
Published: May 2018

Abstract
As culture and the arts gain importance within the agendas of cities, the operation of urban creative clusters is manifested as an effective planning tool for rundown neighbourhoods. Artists and cultural businesses (galleries, theatres, design offices, fashion designers, etc.) form a unique and distinctive sector among other sectors of the economy; their effect on the development and image of a particular neighbourhood can be very important. As part of wider urban processes, city marketing and city branding techniques are often used in order to promote the change in these neighbourhoods and, ideally, prevent negative social effects. The main goal of this paper is to present the experience and implications of the - mostly accidental - formation of a creative cluster in Athens (in the areas surrounding the Athenian part of Piraeus Street) and to critically evaluate the potential role of branding, drawing on the experience of similar efforts in other European cities.

This paper is focused on the role of cultural and creative industries in the regeneration of the inner city of Ostrava. The first part outlines the basic relationship of cultural and creative industries and urban areas in market economies, with emphasis on industrial cities. Ostrava is a post-socialist city, therefore essential characteristics of one are briefly given. The empirical part presents three case studies demonstrating the impact of cultural and creative industries on the regeneration of the inner city of Ostrava. In the conclusion, the case studies are discussed in a comparative perspective with special accent on the role of the public sector as an actor of culture-led regeneration in Ostrava.
From Concepts to Practical Tools of Support: Development of The Creative Sector in Warsaw
Authors: Dudek-Mańkowska Sylwia , Fuhrmann Magdalena 
Published: May 2018

Abstract
Warsaw is a metropolitan city with great creative potential. All the national media as well as editorial offices of most newspapers and periodicals of national circulation are located here. Mass media, educational institutions, and cultural institutions along with a community of educated and affluent people make Warsaw a leading cultural centre both in terms of potential in creative activities and as a market for products coming from the creative sector. Although the creative sector seems to be treated as an important part of the economic base of Warsaw’s development, creative potential located in the city seems to be underused. The goal of this paper is to present the support of city authorities for the development of the creative sector in Warsaw. The evaluation of problems and bottlenecks articulated by representatives of the creative sector will be confronted with the opinions of representatives of the City Hall.
The Holy and the Unholy in Chaucer’S Squire’S Tale
Authors: Czarnowus Anna 
Published: May 2018

Abstract
As Richard Kieckhefer once noticed, “the holy” and “the unholy” were interlocking phenomena in the medieval culture. Such a perspective on religion and magic may, indeed, be seen in possible sources of Chaucer’s Squire’s tale, John Carpini’s Historia Mongalorum and in Historia Tartarorum, attributed either to Benedict the Pole, a member of the 1245 papal mission to Mongols, or to the scribe, “C. de Bridia”. Perhaps Carpini and Benedict projected their Christian perception of magic as connected with religion onto the Tartar world they experienced. The Mongol beliefs they related may have been the very convictions mentioned by Chaucer in the discussion of Cambuskyan’s “secte”. The tale then proceeds to a discussion of magic, but the magic there is no longer “unholy”, as opposed to “the holy”, but technological, manmade, and unnatural. The texts portray two stages in a medieval approach to magic, which were followed by the Renaissance condemnation of magic as heretical. In Squire’s tale magic leads to the experience of wonder, which unites the community.

Authors: Protsakh Nataliya 
Published: May 2018

Abstract
This paper describes the solvability of mixed problem for nonlinear ultraparabolic equation with degeneration. The result is obtained in the cases of the weak and the strong degenerations. The conditions of solvability depend on the relations between the coefficients of the equation and the parameter of degeneration.
Functions with bounded variation in locally convex space
Authors: Duchoˇn Miloslav , Debiève Camille 
Published: May 2018

ABSTRACT
The present paper is concerned with some properties of functions with values in locally convex vector space, namely functions having bounded variation and generalizations of some theorems for functions with values in locally convex vector spaces replacing Banach spaces, namely Theorem: If X is a sequentially complete locally convex vector space, then the function x(・) : [a, b] → X having a bounded variation on the interval [a, b] defines a vector-valued measure m on borelian subsets of [a, b] with values in X and with the bounded variation on the borelian subsets of [a, b]; the range of this measure is also a weakly relatively compact set in X. This theorem is an extension of the results from Banach spaces to locally convex spaces.
Generalized oscillations for generalized continuities
Authors: Borsík Ján 
Published: May 2018

ABSTRACT
Let (X, g) be a generalized topological space, (Y, d) a metric one and f : X → Y a function. We can define a generalized oscillation of f at x ∊ X as kgf (x) = inf{diamf(A) : A ∊ g, x ∊ A}. We discuss some properties of the generalized oscillation.
A predator-prey model with allee effect and fast strategy evolution dynamics of predators using hawk and dove tactics
Authors: Kühnová Jitka , Přibylová Lenka 
Published: May 2018

ABSTRACT
In this work we present the predator-prey model with Allee effect and Hawk and Dove tactics in fighting over caught prey implemented as fast strategy evolution dynamics. We extend the work of Auger, Parra, Morand and S´anchez (2002) using the prey population embodying Allee effect and analogously to this work we get two connected submodels with polymorphic and monomorphic predator population.We get much richer dynamics, in each submodel we find local bifurcations (saddle-node, supercritical Hopf caused by Allee effect and Bogdanov- -Takens) and a global bifurcation of limit cycles caused by the strategy evolution that is not possible in any of the submodels that can lead to a bluesky extinction of both populations.
Hybrid synchronization of n–scroll Chua and Lur’e chaotic systems via backstepping control with novel feedback
Authors: Rasappan Suresh , Vaidyanathan Sundarapandian 
Published: May 2018

Abstract
This paper investigates the backstepping control design with novel feedback input approach for controlling chaotic systems to guarantee the complete synchronization as well as the anti-synchronization of chaotic systems, viz. n-scroll Chua (K. Wallace et.al. 2001) and Lur’e chaotic systems. Our theorems on hybrid synchronization for n-scroll Chua and Lur’e (J.Suyken et.al. 1997) chaotic systems is established using Lyapunov stability theory. Based on the Lyapunov function, the backstepping control is determined to tune the controller gain based on the precalculated feedback control inputs. The backstepping scheme is recursive procedure that links the choice of a Lyapunov function with the design of a controller and guarantees global stability performance of strict-feedback chaotic systems. Since the Lyapunov exponents are not required for these calculations, the backstepping control method is effective and convenient to synchronize the chaotic systems. Mainly this technique gives the flexibility to construct a control law. Numerical simulations are also given to illustrate and validate the hybrid synchronization results derived in this paper
An investigation of nonlinear tangential contact behaviour of a spherical particle under varying loading
Authors: Zabulionis D. , Kačianauskas R. , Markauskas D. , Rojek J. 
Published: May 2018

Abstract.
An analytical and numerical study of the tangential contact of a spherical particle under varying combined normal-tangential loading is presented. The normal and tangential contact is described by the Hertz and regularized Coulomb laws. This study is focused on the analysis of the tangential displacement of the particle’s contact point under variable normal force and reevaluation of the procedures for calculation of the tangential force. The incremental displacement-driven and force-driven constitutive relationships are developed. The importance of an adequate numerical treatment of the tangential component of the contact force is shown for the slide mode, and the recommendations for its evaluation are proposed. The performance of the algorithm is demonstrated by solving the problem of the oblique impact of the spherical particle on the wall. The suggested methodology allows us to analyse the elastic and sliding effects of the tangential interaction more precisely than existing methodologies. Besides, the issue of the direction of the tangential force, when the Coulomb limit is reached, was reconsidered in one-dimensional case by taking three versions of the unit direction vector, which are based on the tangential elastic displacement, tangential stick force, and tangential relative velocity of the contact point of the particle.
Determination of phase diagrams and thermoseparation behaviour of aqueous two-phase systems composed of ethylene oxide–propylene oxide random copolymer and potassium phosphate
Authors: Dembczyński Radosław , Białas Wojciech , Jankowski Tomasz 
Published: May 2018

Abstract
The application of aqueous two-phase systems (ATPS) is a cost-effective and simple method of protein separation (including enzymes) from complex systems. The first stage of designing the protein purification process in an ATPS involves the identification of the conditions for the formation of a given extraction system. For this purpose, the conditions for the formation of ATPSs in a thermoseparating EO50PO50 polymer/potassium phosphates system have been studied. Factors determining the ATPS formation comprised: separation temperature (4ºC or 20ºC), phosphate solution pH (6, 7.5 or 9) as well as the concentration of NaCl introduced into the systems (0.085 M, 0.475 M and 0.85 M). ATPS without NaCl were prepared as well. The conditions for the formation of the primary EO50PO50/potassium phosphate ATPS were determined with their phase diagrams. It was observed that with an increase of phosphate pH and NaCl concentration in the system, there was a decrease of the EO50PO50 and phosphate concentrations necessary to form a primary ATPS. After the primary two-phase separation, the top phase (rich in the EO50PO50 polymer) was partitioned from the bottom phase (rich in phosphates). Next, by means of polymer phase thermoseparation, a secondary two-phase system was formed. In the secondary EO50PO50/phosphate ATPS, the bottom phase was formed by the concentrated EO50PO50 polymer (30-80% concentration), while the top phase by a solution composed mainly of water, containing phosphate ions and remains of EO50PO50 polymer (3-7%).
A key metric and its calculation models for a continuous diagnosis capability base dependency matrix
Authors: Shi Jun-You , Lin Xie-Gui , Shi Meng 
Published: May 2018

Abstract
This paper is devoted to measuring the continuous diagnosis capability of a system. A key metric and its calculation models are proposed enabling us to measure the continuous diagnosis capability of a system directly without establishing and searching the sequential fault tree (SFT) of the system. At first a description of a D matrix is given and its metric is defined to determine the weakness of a continuous diagnosis. Then based on the definition of a sequential fault combination, a sequential fault tree (SFT) is defined with its establishment process summarized. A key SFT metric is established to measure the continuous diagnosis capability of a system. Two basic types of dependency graphical models (DGMs) and one combination type of DGM are selected for characteristics analysis and establishment of metric calculation models. Finally, both the SFT searching method and direct calculation method are applied to two designs of one type of an auxiliary navigation equipment, which shows the high efficiency of the direct calculation method.
