Characteristics of Sorel cement prepared from impure materials
Authors: Jurišová Jana , Fellner Pavel , Pach Ladislav 
Published: December 2015

Abstract
Production of potassium nitrate from potassium chloride and magnesium nitrate is related with the production of by-product, which is water solution of MgCl2 having concentration (24-30) mass %. Along with magnesium chloride this solution contains also nitrates and potassium and calcium cations. This solution can be used as defrosting agent or as a component for the production of building material based on Sorel cement. Sorel cement is material originating from the reaction of MgCl2 solution with solid MgO of suitable reactivity which depends on the temperature of calcinations of MgCO3 and size of MgO particles. Sorel cement paste is prepared by mixing MgO and MgCl2 in molar ratio 9 : 1 with the addition of water in appropriate amount. This cement settles in 2 hours and it can be treated within 24 hours, depending on the reactivity of MgO. This paper deals with the preparation and properties| of Sorel cement made of by-product (MgCl2) from the production of fertilizer KNO3 and MgO prepared from Slovak magnesite (Jelsava) with high content of impurities. We will show that properties of this material are suitable for application in building industry.

Published: December 2015

Abstract
A novel protocol for the simple and rapid determination of nicotine using square-wave voltammetry at boron-doped diamond electrode was developed. The effect of pH of supporting electrolyte, scan rate and square-wave voltammetric parameters was examined. Behavior study revealed that nicotine provided two irreversible oxidation peaks, the first one well-shaped at +1.14 V and the second one poorly-defined at +1.61 V vs. Ag/AgCl electrode in the presence of phosphate buffer (pH 9.0). Under optimal experimental conditions (modulation amplitude of 40 mV, frequency of 50 Hz and scan rate of 0.225 V · s-1), the current response of nicotine was proportionally linear in the concentration range from 9.9 × 10-6 to 1.7 × 10-4 mol · L-1 (R2 = 0.996) with the detection limit of 6.1 × 10-6 mol · L-1 (0.989 mg · L-1) and the relative standard deviation of 8.8 % (number of measurements n = 10, 5.7 × 10-5 mol · L-1 nicotine). The proposed procedure was applied to the quantification of nicotine in cigarettes and chewing gums with the determined values in good agreement with those declared by producer. In this respect, the developed protocol could represent an effective and rapid alternative to chemically modified electrodes in analysis of alkaloids.
Design and characterization of a soft magneto-rheological miniature shock absorber for a controllable variable stiffness sole

Published: December 2015

Abstract
The proposed paper discusses the design and characterization of a soft miniature Magneto-Rheological (MR) shock absorber. In particular, the final application considered for the insertion of the designed devices is a controllable variable stiffness sole for patients with foot neuropathy. Such application imposes particularly challenging constraints in terms of miniaturization (cross-sectional area ≤ 1.5 cm2, height ≤ 25 mm) and high sustainable loads (normal loads up to 60 N and shear stresses at the foot/device interface up to 80 kPa) while ensuring moderate to low level of power consumption. Initial design considerations are done to introduce and justify the chosen novel configuration of soft shock absorber embedding a MR valve as the core control element. Successively, the dimensioning of two different MR valves typologies is discussed. In particular, for each configuration two design scenarios are evaluated and consequently two sets of valves satisfying different specifications are manufactured. The obtained prototypes result in miniature modules (external diam. ≤ 15 mm, overall height ≤ 30 mm) with low power consumption (from a minimum of 63 mW to a max. of 110 mW) and able to sustain a load up to 65 N. Finally, experimental sessions are performed to test the behaviour of the realized shock absorbers and results are presented.
Modeling and comparison of superconducting linear actuators for highly dynamic motion
Authors: Bruyn B.J.H. de , Jansen J.W. , Lomonova E.A. 
Published: December 2015

Abstract
This paper presents a numerical modeling method for AC losses in highly dynamic linear actuators with high temperature superconducting (HTS) tapes. The AC losses and generated force of two actuators, with different placement of the cryostats, are compared. In these actuators, the main loss component in the superconducting tapes are hysteresis losses, which result from both the non-sinusoidal phase currents and movement of the permanent magnets. The modeling method, based on the H-formulation of the magnetic fields, takes into account permanent magnetization and movement of permanent magnets. Calculated losses as function of the peak phase current of both superconducting actuators are compared to those of an equivalent non-cryogenic actuator.
Modular transportation system with a three dimensional routeing
Authors: Löffler Christoph , Canders Wolf-Rüdiger 
Published: December 2015

Abstract
In intra-enterprise logistics and automation of manufacturing processes general a rising productivity by high flexibility is required. Existing transportation systems exclusively use two-dimensional track sections, because they can be served with standard drives. Because of these simple structures the transport speed is limited and thereby also the throughput. In this paper now a modular transportation system is presented which could reach higher speeds with a direct drive and the use of centrifugal force compensating curves. Simultaneously the system also can change the altitude. All this succeeds with the integration of three-dimensional track sections. Therefore a two piped guiding system with a long stator linear motor was designed. To combine the linear motor with the three dimensional track special stator elements were developed which allow a bending of the stator to follow the route course. The current work deals with the implementation of a mechanical passive switch, which is operated by the electromagnetic forces of the linear motor. So no additional mechanical actors or a separate electromagnetic system are necessary.
Political Pathology in Plato’s Republic
Authors: Brill Sara 
Published: December 2015

AbstractThis paper focuses on the influence of the language of medical diagnosis, prognosis and treatment at an important juncture in the inquiry into psuchē Plato undertakes in the Republic: the discussion of degenerate regimes and forms of soul in Books 8 and 9. I argue that the work that is accomplished by Plato’s critical appropriation of medical terms and concepts is crucial to the dialogue as a whole: it gives us insight into the deepest questions and problems animating the dialogue, namely, how to choose the best life possible, and what role philosophy has in this task. More specifically, I argue that the medically inflected psychological and political diagnostics that Socrates employs in the analysis of civic and psychic decay in Books 8 and 9 produces a sophisticated critical theory, one which takes as its object of analysis neither the city nor the soul by themselves, but rather the peculiar degenerating operation of desire that is common to both, and which hinges upon the capacity for self-analysis of the diagnostician. This critical theory is further developed by the fusion of medical and juridical stances that is operative in the judgment of lives with which Book 9 concludes.
Student Motivation in the 21st Century – Slovak Experience
Authors: Rozvadský Gugová Gabriela , Maťovčíková Daniela 
Published: December 2015

Abstract
One of the five primary objectives of the European Union within the framework of Europe 2020 is to increase the proportion of the tertiary educated population. The research task titled “The motivation of the student in the 21st century” is intended to address the factors that have both an impact on the decision of students to pursue higher studies and affect the choice of a specific field of study and a preferred form of study. The stimulus to the exploration was sparked by the mentioned EU initiative, interesting statistical data, the growing number of students studying in the external form compared to the daily option, and an increase of students from abroad. Therefore, it is necessary to identify the causes of these trends. Motivation of students is not researched in a systematic way in Slovakia, even though it is an important factor in a student’s decisionmaking process to study. Information was obtained by a questionnaire distributed to 105 students, evaluated using SPSS software and application of descriptive statistics.

Differences in the Value Orientation of Czech and Slovak Pupils
Authors: Vomáčková Helena 
Published: December 2015

Abstract
This contribution brings a selection from the results of a research carried out during the years 2013 and 2014 among Czech and Slovak pupils of middle school age (i.e. 4th to 6th forms of primary schools). This study focused on monitoring and evaluating the differences and similarities in the value-oriented responses of pupils, according to the criteria of their nationality and sex. The pupils were expressing their opinions by means of a questionnaire survey with respect to selected situations on a four-degree scale and they further stated their vision of the world and their position in it. This contribution analyses statistically significant deviations which were found out among the positions held by Czech and Slovak boys and girls. The contribution also gives rise to a number of questions concerning the shift in values among the population of pupils of the formerly unified state.
The Strategic Use of Innovation to Influence Environmental Policy: Taxes versus Standards
Authors: Moner-Colonques Rafael , Rubio Santiago J. 
Published: December 2015

Abstract
This paper evaluates the strategic behavior of a polluting monopolist to influence environmental policy, either with taxes or with standards, comparing two alternative policy games. The first of the games assumes that the regulator commits to an ex-ante level of the policy instrument. The second one is the time-consistent policy game. We find that the strategic behavior of the firm is welfare improving and leads to more environmental innovation than under regulatory commitment if a tax is used to control pollution. However, the contrary occurs if an emission standard is used. Under commitment, it is shown that both policy instruments are equivalent. We conclude that the optimal environmental policy is to use an emission tax since it yields the same welfare level than an emission standard for a committed regulator yet a larger welfare for a non-committed regulator.
Identifying conventional and unconventional monetary policy shocks: a latent threshold approach
Authors: Kimura Takeshi , Nakajima Jouchi 
Published: December 2015

AbstractThis paper proposes a new estimation framework for identifying monetary policy shocks in both conventional and unconventional policy regimes using a structural VAR model. Exploiting a latent threshold modeling strategy that induces time-varying shrinkage of the parameters, we explore a recursive identification switching with a time-varying overidentification for the interest rate zero lower bound. We empirically analyze Japan’s monetary policy to illustrate the proposed approach for modeling regime-switching between conventional and unconventional monetary policy periods, and find that the proposed model is preferred over a nested standard time-varying parameter VAR model. The estimation results show that increasing bank reserves lowers long-term interest rates in the unconventional policy periods, and that the impulse responses of inflation and the output gap to a bank reserve shock appear to be positive but highly uncertain.
Darkness on Screen: Subjectivity-Inducing Mechanisms in Contemporary Estonian Art Film
Authors: Oja Martin 
Published: December 2015

Abstract
The main purpose of the article is to bring more clarity to the concept of art film, shedding light on the mechanisms of subjective reception and evaluating the presence of subjectivity-inducing segments as the grounds for defining art film. The second aim is to take a fresh look at the littlediscussed Estonian art cinema, drawing on a framework of cognitive film studies in order to analyse its borders and characteristics. I will evaluate the use of darkness as a device for creating meaning, both independently of and combined with other visual or auditory devices. The dark screen, although not always a major factor in the creation of subjectivity, accompanies the core problem both directly and metaphorically: what happens to the viewer when external information is absent? I will look at the subjectivity- inducing devices in the films of two Estonian directors, Sulev Keedus and Veiko Õunpuu. For the theoretical background, I rely mostly on Torben Grodal’s idea about the subjective mode as a main characteristic of art film, and the disruption of character simulation as the basis for the film viewer’s subjectivity.
Strategic Management of Crossmedia Production at Estonian Public Broadcasting
Authors: Ibrus Indrek , Merivee Astra 
Published: December 2015

Abstract
This article investigates the strategies behind the production of crossmedia content at Eesti Rahvusringhääling (ERR), Estonia’s public broadcaster. The empirical work that supports its analytic objectives consists of multiple methodologically varying sub-studies: a textual analysis of ERR’s existing online presence and crossmedia content; 32 semi-structured interviews with its various top- and mid-level managers; and a documentary analysis of its associated strategies, guidelines, and communications. The paper suggests that, despite ERR’s advanced presence on digital platforms, it notably lacks a more comprehensive strategy for crossmedia content production and for achieving better inter-organisational cooperation that would enable new production processes. Although a few more advanced crossmedia productions have taken place, these have tended to emerge ad hoc - out of initiatives from individual employees. The article, however, suggests that, despite the current lack of an organisational strategy, the experiences acquired by its employees are creating a timely momentum for using interpretative and adaptive approaches to developing its new crossmedia production strategies.
Constructing National Identity in Soviet Estonian Documentary Cinema: A Case Study of the Documentary Ruhnu (1965) by Andres Sööt
Authors: Västrik Riho 
Published: December 2015

Abstract
This article aims to find out how Soviet Estonian documentaries constructed the national discourse in the 1960s, by focusing on the case of the 10-minute documentary Ruhnu (1965) by Andres Sööt. Ruhnu was the first Soviet Estonian documentary released after World War II that romanticised Estonian nationalism. In order to narrate the national ideals considered undesirable by the official ideology, the Soviet Estonian filmmakers often chose to portray characters embedded in the national consciousness as archetypal heroes from pre-Soviet times and the landscapes associated with them. In the desire for past times, national heroes and idealised landscapes were constructed and naturalised in a contemporary context. The article raises the question - what kind of heroes, landscapes and activities were used to construct the national identity and which elements of film language were used? The research method used, critical discourse analysis, allows us to analyse the archetypes created in the documentary and the archetypal landscapes used as a framework for the narrative.
Slowly Moving Bodies: Signs of Pictorialism in Aki Kaurismäki’s Films
Authors: Valkola Jarmo 
Published: December 2015

Abstract
Aki Kaurismäki is arguably the best-known Finnish filmmaker, owing largely to his feature films such as Crime and Punishment (Rikos ja rangaistus, Finland, 1983), Calamari Union (Finland, 1985), Shadows in Paradise (Varjoja paratiisissa, Finland, 1986), Hamlet Goes Business (Hamlet liikemaailmassa, Finland, 1987), Ariel (Finland, 1988), The Match Factory Girl (Tulitikkutehtaan tyttö, Finland, 1990), I Hired a Contract Killer (Finland/ Sweden, 1990), La vie de bohéme (Finland/France/ Sweden/Germany, 1992), Take Care of Your Scarf, Tatiana (Pidä huivista kiinni, Tatjana, Finland/Germany, 1994), Drifting Clouds (Kauas pilvet karkaavat, Finland, 1996), Juha (Finland, 1999), The Man Without a Past (Mies vailla menneisyyttä, Finland, 2002), Lights in the Dusk (Laitakaupungin valot, Finland, 2006) and Le Havre (Finland/France, 2011). A large body of his work has been made in Finland, but also in countries like France and Great Britain. Besides feature films, he has also made documentaries and short films, as well as musical films with the group Leningrad Cowboys. In a broader context, Kaurismäki has a unique place in Finnish and international film history, as well as in media and communication culture. Kaurismäki’s cultural context includes elements that have been turned into national and transnational symbols of social communication and narrative interaction by his stylisation. The director’s cinematic strategy investigates and makes choices evoking a social understanding of characters that has special communicative value. Kaurismäki’s films have been scrutinised for over thirty years.
Folk Elements in Aleksei Balabanov’s Brat and Brat 2: A Morphological Analysis
Authors: Schuckman Matthews Emily 
Published: December 2015

Abstract
The article uses Vladimir Propp’s Morphology of the Folktale (Морфолоƨuя сказкu, 1928) as a framework to illustrate the way in which Aleksei Balabanov masterfully creates a modern folk tale using classic motifs and structures in his 1997 film Brother (Браm, Russia) and its sequel Brother 2 (Браm 2, Russia, 2000). The paper argues that Brother and Brother 2 are post-Soviet retellings of classic tales of Russian folklore and that Danila is a modern hero, an unlikely saviour of the Russian nation and the Russian soul. Danila’s journey is formulaic, predictable and straightforward, yet nevertheless makes for a powerfully new take on concepts of Russian nationalism and heroism. The underworld to which our hero must journey is located in the heart of Russia’s ‘Peter’, and possession of the Russian nation and soul are the object of his quest in the volatile post-Soviet period.

AbstractElectrophilic aromatic substitution is one of the most thoroughly studied reactions in organic chemistry. In the present paper, the 5-brominated spirobrassinol methyl ethers VII, VIII were obtained by electrophilic substitution of the aromatic core of indoline at the C-5 position in the presence of various brominating agents. The same products were also prepared from 5-bromoindole (IX ) following the sequence for the synthesis 1-methoxyspirobrassinol methyl ether (V) from indoline. In addition, the new related 5-bromospiroindoline derivatives XX-XXIII were synthesised and their biological activity on human tumour cell lines was examined. The presence of bromine in the indole or indoline skeleton at the C-5 position resulted in the partial increase in anticancer activity on leukaemia cell lines (Jurkat, CEM). The structures of the newly prepared products were determined by
