Spojka Kým V Sémantických A Komunikačných Súvislostiach
Authors: Sokolová Jana 
Published: July 2015

Abstract
The study focuses on the communication-oriented analysis and interpretation of semantic and communicative (illocutive) functions of the Slovak conjunction kým [‘while’]. Research is based on the text material of the Slovak National Corpus containing synchronic dynamics of the sentence in which the conjunction kým [‘while’] expresses temporal and/or contrastive meanings. Kým [‘while’] is understood as a poly-semantic and poly-functional word which forms relations of limitative, successive, simultaneous and contrastive-simultaneous coincidence between an independent clause (P) and a whileclause (Q). Regarding the semantic functions of the conjunction, the study also discusses the function of temporal and pragmatic collocations, and complementary and competitive use of synonymous conjunctions. It verifies the connections between the actual dispositions of the conjunction kým [‘while’] and a dialogic or narrative interpretation, the choice of perspective and the sentence order. A part of the study presents the use of the conjunction kým [‘while’] in the communicative functions of assertion, direction, interrogation, satisfaction, commission and admonition. It demonstrates the dominance of illocutions which are based on the negative life experience of a speaker

Abstract
We consider a model time-harmonic wave equation of acoustic tomography of moving fluid in an open bounded domain in ℝ
d
, d ≥ 2, with variable sound speed c, density ρ, fluid velocity v and absorption coefficient α. We give global uniqueness results for related inverse boundary value problem for the cases of boundary measurements given for two and for three fixed frequencies. Besides, we also give a non-uniqueness result for this inverse problem for the case of boundary measurements given for all frequencies.
xAAL: A Distributed Infrastructure for Heterogeneous Ambient Devices
Authors: Lohr Christophe , Tanguy Philippe , Kerdreux Jérôme 
Published: July 2015

AbstractAmbient assisted living systems are based on sensors and actuators, with a diversity of network protocols and vendors. This commonly leads to the introduction of gateways or middlewares into the technical infrastructure in order to address interoperability issues. The xAAL framework presented in this paper aims to provide interoperability and to redesign such “gateways” into well-defined functional entities communicating with each other via a lightweight message bus over IP. Each entity may have multiple instances, may be shared between several boxes, and may be physically located in any box. Thanks to the distributed architecture of the system, each home automation vendor may peacefully provide its own xAAL box without revealing details of its technology. Also, several applications may be plugged together on the xAAL bus without getting bored with underlying heterogeneity. Moreover, the management of the dynamicity allows sensors or applications to enter and leave the system at any time.
Perception of emotions in
mild cognitive impairment
and Alzheimer’s dementia:
does intensity matter?
Authors: Elferink Maaike Waanders-Oude , van Tilborg Ilse , Kessels Roy P.C. 
Published: July 2015

Abstract
Background: To provide a review of the literature on the perception of emotion in Alzheimer’s dementia (AD) and
Mild cognitive impairment (MCI), and to evaluate if emotion intensity matters.
Methodology: A systematic literature search of PubMed database was carried out using combinations or
truncated versions of the keywords “MCI”, ”Alzheimer”, “emotion recognition”, “facial emotion recognition”, “social
cognition” or “emotion perception”. Twenty-eight articles were found to meet the inclusion criteria.
Results: Overall, AD patients performed worse on emotion perception than MCI patients and healthy controls.
Half of the studies found an emotion-specific deficit for MCI patients on the emotions anger, sadness and fear.
However, studies taking emotion intensity into account are still scarce.
Conclusions: An emotion-intensity based approach may be more sensitive to detect subtle impairments in facial
emotion recognition. Future studies need to take emotion intensity into account and also consider confounding
factors such as overall cognition and mood.
Gramofon w kręgu reinterpretacji / Gramophone Reinterpretations
Authors: Białas Maciej 
Published: July 2015

AbstractWhat is most surprising in the 150-year history of the gramophone (phonograph, record player) is that it has not ended even today. It might appear that progress in phonography which took place in the twentieth century should have made the gramophone a relic of the industrial age. Investigating the reasons why this device is still alive, the author argues that if it survived all through the twentieth century and found is place in the digital age on the eve of the new century, it was only owing to its hidden potential, which allowed creative individuals to rediscover it, find its new uses, attribute new functions and assign it new roles; in short, reinterpret it in diverse ways, the outcome being gramophone music - a new discursive practice with a varied esthetic appearance.In the first part of the study the author refers to the history of those gramophone reinterpretations and successively describes early literary impressions of the gramophone, the phonograph postulates of Lászlo Moholy-Nagy, Paul Hindemith’s and Ernst Toch’s Grammophonmusik, John Cage’s Imaginary Landscapes, the art of D.J.’s and turntablists, Christian Marclay “creative gramophony”, and experimental turntablism.The second part of the article analyzes the esthetics of gramophone music. The author distinguishes three trends in it: in the first the gramophone is subordinated to the classical concept of music, in the second it is used to create poly-style sound collages, in the third the gramophone is the tool for the implementations of the principles of conceptual art.In conclusion the author writes that it is chiefly owing to these reinterpretations which made the sound-recording and playback invention a composer’s tool, a musical instrument and finally an object of elaborate artistic experiments that the gramophone was able to carry out a historic, technological and conceptual revolution in the twentieth-century and early twenty-first century culture.
Persephassa. Xenakisa architektura brzmieniowa dla sześciu perkusistów Persephassa. / Xenakis’s Sound Architecture for Six Percussionists
Authors: Halat Stanisław 
Published: July 2015

AbstractMusical pieces composed for a percussion ensemble form a significant portion of Iannis Xenakis’s creative achievements. One of major compositions in this genre is his Persephassa (1969) for six percussionists. The set of instruments used by Xenakis is divided into four sound levels: skins (peaux), pieces of wood (bois), metals (metal), effects (pierre). Each percussionist has a wide acoustic array consisting of over a dozen instruments. The sonoric aspect of the piece is enriched through the positioning of the musicians around the audience. The first part of the paper analyzes the form of the composition: its course, division, structural, rhythmical, textural, agogic, energy-containing, and sound solutions, as well as the kinds of culminations and special effects (rhythmical chaos). The other part of the article describes the use of compositional devices that determine the specificity of a musical piece, such as complicated rhythmical structuralism, (resulting from the combinations of elements of probability calculus and computer algorithms) or sonoric effects (e.g. “sound clouds”), discussed in close connection with the problems of performing technique.
Musical Evita Andrew Lloyda Webbera na tle wybranych gatunków muzyki scenicznej XIX i XX wieku* / Andrew Lloyd Webber’s Musical Evita in the Context of Selected Genres of Nineteenth and Twentieth-Century Stage Music
Authors: Bernatowicz Wojciech 
Published: July 2015

AbstractThe analytical study of Andrew Lloyd Webber’s musical Evita contains inter alia the description of the libretto, and the analysis of architectural-formal, rhythmical, and melodic features and stylization devices. In architectural terms, Evita shows the influences of operetta, heroic opera, and musical drama (e.g. in large integrated blocks of scenes, and characteristic final scenes). In the internal formal relations in the piece, the links with the nineteenth-century heroic opera are observable. Regarding the use of form, the composers utilizes those that appeared in Romantic Italian and French operas, while the stylization devices present in the piece have their reference to the nineteenth-century operatic forms in France and operetta compositions. An important structural element of Evita is reminiscence motifs referring inter alia to grand opera. The conscious use of these motifs on such a large scale that have no equivalents in operetta or in the genres preceding the emergence of musical, and in other musicals, causes Evita to be closer to opera in its motivic concept. Owing to the exceptional musical language combining tradition and the present, Webber’s work is an example that the musical as a form of sublime entertainment can also satisfy the requirements of high art.
On mechanism of the bubble bouncing from hydrophilic and hydrophobic solid surfaces
Authors: Zawała Jan , Zawała Piotr , Małysa Kazimierz 
Published: July 2015

AbstractThe kinetics of collision and bouncing of an air bubble on hydrophilic and hydrophobic solid surfaces immersed in distilled water is reported. We carried out the experiments and compared the bubble collision and bouncing courses on the stagnant and vibrating, with a controlled frequency and amplitude, solid/liquid interface. For stagnant interface differences in the outcome of the bubble collisions with hydrophilic and hydrophobic solid surfaces are resulting from different stability of the intervening liquid film formed between the colliding bubble and these surfaces. The liquid film was unstable at Teflon surface, where the three-phase contact (TPC) and the bubble attachment were observed, after dissipation of most of the kinetic energy associated with the bubble motion. For vibrated solid surface it was shown that kinetics of the bubble bouncing is independent on the hydrophilic/hydrophobic properties of the surface. Similarly like at water/glass hydrophilic interface, even at highly hydrophobic Teflon surface time of the bubble collisions and bouncing was prolonged almost indefinitely. This was due to the fact that the energy dissipated during the collision was re-supplied via interface vibrations with a properly adjusted acceleration. The analysis of the bubble deformation degree showed that this effect is related to a constant bubble deformation, which determined constant radius of the liquid film, large enough to prevent the draining liquid film from reaching the critical thickness of rupture at the moment of collision. The results obtained prove that mechanism of the bubble bouncing from various interfaces depends on interrelation between rates of two simultaneously going processes: (i) exchange between kinetic and surface energies of the system and (ii) drainage of the liquid film separating the interacting interfaces.
Wetting properties of the sodium bis(2-ethylhexyl) sulfosuccinate (AOT) and polyoxyethylene (23) lauryl ether (Brij 35) binary mixtures in the poly(tetrafluoroethylene)-solution-air system
Authors: Krawczyk Joanna 
Published: July 2015

AbstractWettability of poly(tetrafluoroethylene) (PTFE) by aqueous solutions of binary mixtures composed of sodium bis(2-ethylhexyl) sulfosuccinate (AOT) with polyoxyethylene (23) lauryl ether (Brij 35) was considered on the basis of the measured values of contact angle and surface tension. It was shown that the value of the critical surface tension of PTFE surface wetting at the studied system (23.5 mN/m), does not depend on the concentration and composition of the binary mixtures of studied surfactants in water, and it was higer than the surface tension of PTFE (20.2 mN/m). The best wettability of polytetrafluoroethylene (PTFE) by studied aqueous solutions of binary surfactants mixtures occurs at the mixtures concentration corresponding to the critical micelle concentration of their solutions.
New Data about Ore-Bearing of the Neoproterozoic Flood Basalts (the Ratno Beds, Volhyn, Ukraine) / Nowe dane dotyczące rudonośnych pokryw lawowych z neoproterozoiku (skały osadowe, pokłady, struktury sedymentacyjne w Ratnie, Wołyń, Ukraina)

AbstractWzory rozprowadzenia drugorzędnej mineralizacji i kwestia tektonicznej kontroli mineralizacji powinny zostać rozpoznane w celu identyfikacji cech formowania się metali naturalnych w pokrywach lawowych z neoproterozoiku (Wołyń, Ukraina). Metoda klasyfikacji zmian pozwoliła na stworzenie mapy pęknięć w strukturach sedymentacyjnych w Ratnie w najniższym potoku w celu określenia intensywności pękania skał w strefie uskoku w Czartorysku. W celu ustalenia cech rozprowadzania mineralizacji metali naturalnych w neoproterozoicznych bazaltach przeprowadzono badania mineralogiczne, petrograficzne i geochemiczne. Analiza chemiczna skał wulkanicznych z miedzią, srebrem i złotem została wykorzystana do stworzenia schematów rozprowadzania metali w najniższym potoku bazaltu w strukturach sedymentacyjnych w Ratnie. Dzięki temu dowiadujemy się, że skały wulkaniczne w strefie uskoku w Czartorysku przeszły wiele zmian. Neoproterozoiczne pokrywy lawowe przeszły zmiany w sposób nierównomierny i charakteryzują się podwyższoną koncentracją metali szlachetnych. Regionalne zmiany przybierają formę palagonitu, chlorytu, zeolitów, chalcedonów i analcymów. Wykazano, że kształtowanie nasyconej mineralizacji metali naturalnych (miedź, srebro, nikiel, chrom) jest związane z regionalnymi zmianami w potoku bazaltu w Ratnie. W strefach o podwyższonym pękaniu i brekcji występują kwarc niskotemperaturowy, karbonity i siarczki rozprowadzane miejscowo. Miejsca ostatniej mineralizacji metali (złoto, srebro, ołów) również są miejscowe i związane ze strefami brekcji.
The Spatial Variability of Ridge and Runnel Beach Morphology Due to Beach Placer Mining along the Vembar – Kallar Coast, India / Przestrzenna zmienność morfologii plaży pod kątem grzbietów i strumieni spowodowana powstaniem kopalni złóż okruchowych wzdłuż Vembar – Wybrzeże Kallar w Indiach

AbstractCelem tej pracy jest omówienie przestrzennych i krótkotrwałych zmian w morfologii plaży pod kątem grzbietów i strumieni na podstawie profili plaży w Vembar, na wybrzeżu Kallar, Tamil Nadu, Indie. Plaże składają się głównie z średniego do grubego piasku i ciężkich minerałów. Dla plaż charakterystyczne są grzbiety, strumienie i zagłębienia. Grzbiety i strumienie są niewielkie ze względu na prace kopalniane prowadzone w okolicy. Ustalono, że przestrzenne i tymczasowe zmiany w systemie grzbietów i strumieni są kontrolowane przez pianę morską/łamiące się fale. Zmiany objętości sedymentu wynikają z nieregulowanej aktywności kopalni. Erozja ma wpływ na profil wszystkich plaż, zwłaszcza strumieni. Strefy przyrostu znajdują się wyżej, to znaczy na najwyższych grzbietach i wałach plażowych. Krótkotrwałe zmiany wielkości plaży wyjaśniają zniekształcenie grzbietów i strumieni. Ma to związek z pobliską kopalnią. Zaobserwowano wzorzec wiatru wyżej plaży, gdzie warunki pozwalają na transport sedymentu piasku i jego ruch na grzbietach i strumieniach.
Wpływ turystyki na wybrane właściwości gleb na ścieżce dydaktycznej Bukowa Góra (Roztoczański Park Narodowy, Wschodnia Polska) / Impact of Tourism on Selected Properties of Soils of Bukowa Góra Educational Path (Roztoczański National Park, Eastern Poland)

AbstractCelem przeprowadzonych badań jest analiza zmian zachodzących w glebie w wyniku pieszego ruchu turystycznego w obrębie ścieżki dydaktycznej na Bukową Górę w Roztoczańskim Parku Narodowym (RPN). Rezerwat leśny Bukowa Góra położony jest na południe od miasta Zwierzyniec (Roztocze Środkowe, Polska E). Ze względu na dużą atrakcyjność przyrodniczą i krajobrazową już w 1934 roku utworzono tu rezerwat, którego powierzchnia nie przekraczała 8 ha. Celem ochrony jest zachowanie pięknych drzewostanów jodłowych i jodłowo-bukowych, wchodzących w skład zespołów wyżynnego boru jodłowego i buczyny karpackiej oraz zabezpieczenie rzadkich przedstawicieli fauny i flory. W wyniku udeptywania zmianom ulegają niektóre cechy morfologiczne powierzchniowych poziomów genetycznych. Dotyczy to przede wszystkim poziomu organicznego O, którego brak w profilach na ścieżce, a także poziomu próchnicznego A, nadbudowanego deluwiami w profilach zlokalizowanych w dolnych partiach ścieżki. Ponadto w glebach poddanych presji turystycznej zmniejsza się na ogół wilgotność aktualna, kapilarna pojemność wodna i maksymalna pojemność wodna, natomiast wzrasta gęstość objętościowa w porównaniu z glebami kontrolnymi poza ścieżką. Zależność ta jest najbardziej widoczna na głębokości 0-5 cm. Dodatkowo gleby występujące na ścieżce cechują się wyższymi wartościami pH oraz niższymi wartościami kwasowości hydrolitycznej i pojemności sorpcyjnej.

AbstractIn this paper we study some distance properties of outerplanar graphs with the Hamiltonian cycle whose all bounded faces are cycles isomorphic to the cycle C4. We call this family of graphs quadrangular outerplanar graphs. We give the lower and upper bound on the double branch weight and the status for this graphs. At the end of this paper we show some relations between median and double centroid in quadrangular outerplanar graphs

AbstractA singular stochastic control problem in n dimensions with timedependent coefficients on a finite time horizon is considered. We show that the value function for this problem is a generalized solution of the corresponding HJB equation with locally bounded second derivatives with respect to the space variables and the first derivative with respect to time. Moreover, we prove that an optimal control exists and is unique

AbstractRNA binding proteins (RBPs) are involved in many cellular functions. To facilitate functional characterization of RBPs, we generated an RNA interference (RNAi) library for Drosophila cell-based screens comprising reagents targeting known or putative RBPs. To test the quality of the library and provide a baseline analysis of the effects of the RNAi reagents on viability, we screened the library using a total ATP assay and high-throughput imaging in Drosophila S2R+ cultured cells. The results are consistent with production of a high-quality library that will be useful for functional genomics studies using other assays. Altogether, we provide resources in the form of an initial curated list of Drosophila RBPs; an RNAi screening library we expect to be used with additional assays that address more specific biological questions; and total ATP and image data useful for comparison of those additional assay results with fundamental information such as effects of a given reagent in the library on cell viability. Importantly, we make the baseline data, including more than 200,000 images, easily accessible online.

Published: July 2015

ABSTRACTSelectively-absorbing nanofluids were synthesized and evaluated for spectrum splitting PV/T collector applications. Core-shell silver-silica (Ag-SiO2) nanodiscs and multi-walled carbon nanotubes (MWCNTs) were suspended in water at varying dilutions and then tested as an optical filter placed between a light source and silicon solar cell. A concentrated Ag-SiO2 solution diluted with an aqueous MWCNT solution yielded higher thermal efficiencies than when diluted by the same volume of water. However, AgSiO2-MWCNT mixtures yielded a lower electrical output than aqueous AgSiO2 dilutions due to the non-selective absorption of MWCNTs. The most concentrated Ag-SiO2 nanofluid (0.026wt%) yielded a peak thermal efficiency of 65%, to deliver the greatest combined efficiency of ∼72%.
Structure and conductivity of fuel cell membranes and catalytic layers investigated by AFM
Authors: Hiesgen Renate , Morawietz Tobias , Handl Michael , Friedrich K. Andreas 
Published: July 2015

ABSTRACTIn this work, the structure and conductive structure of perfluorinated sulfonated ionomers were investigated by tapping mode, material sensitive atomic force microscopy (AFM). At cross section of membranes, large ordered lamellar-like areas were found. From adhesion force mappings, approximately 50 nm large water-rich areas could be identified by their low adhesion. These areas were interpreted as ionically conductive phase. They appeared circular and isolated before any forced current flow through the sample (activation). After activation, branched, long and flat ionically conductive phase structures in direction of applied voltage were found. They were interpreted as the formation of a continuous ionically conducting network formed by the current flow. In a second part, the material sensitive imaging was used to analyze the distribution of ionomer and platinum covered carbon particles in fuel cell electrodes. The analysis was based on the high adhesion of ionomers compared to the carbon supported catalyst particles.
