Continuing Professional Development: Understanding arrhythmias: paroxysmal supraventricul artachycardia in the prehospital setting
Authors: Smith Gavin , Boyle Malcolm 
Published: September 2016

Overview Paroxysmal supraventricular tachycardia (PSVT) presents a challenging assessment to the prehospital emergency care provider. The nature of PSVT affects all age groups, has a range of aetiologies, is usually well tolerated but may also result in sudden cardiac arrest. It is able to be terminated by a range of therapies and is the subject of an evolving understanding of pathophysiology related to it. Therefore, it is essential that those providing prehospital care have an understanding of the nature and implications of PSVT in order to effectively manage this condition in the field. This module will use a systematic approach to highlight the pathophysiology, epidemiology, interventions, and issues, to arm the reader with the necessary knowledge to approach this patient with confidence. Learning Outcomes After completing this module you will be able to: • Discuss the pathophysiology of supraventricular tachycardia (SVT) (atrioventricular nodal re-entrant tachycardia (AVNRT) and atrioventricular re-entrant tachycardia (AVRT)) in relation to physiological effects on the body, specifically perfusion and likely deterioration to lethal arrhythmias. • Discuss the treatment modalities available in the prehospital setting for paroxysmal supraventricular tachycardia (PSVT)—specifically the use of vagal manoeuvres, pharmacological agents, and synchronized cardioversion. • State the evidence-based components of the valsalva manoeuvre (VM), and describe their effect. • Describe the rationale for use of the VM in the setting of haemodynamically stable SVT as a firstline intervention. • Outline the controversies and continued development of the VM, and how this may impact upon current reversion rates for SVT.
The Enigma of Consciousness – Philosophic and Scientific Approach
Authors: A Skutchanova A , Saniova B 
Published: September 2016

AbstractConsciousness is enigmatic beast. It is present with us, comforting, and intuitive core of us. Yet this familiar beast, if we try to touch and describe it, escapes. Questioning and exploring consciousness accompanies mankind since ever. In 20thcentury we met never before seen states of severe disorders of consciousness – nonresponding people with eyes wide open. Also advancements in general anesthesia made us reexplore this phenomena.Article sums up current philosophic and two most prominent current neuroscientific approaches to what consciousness is and how we can assess it in other human beings. These theories may extend our understanding of ourselves and also help to asses this core quality in our patients in moments, when they do not intelligibly respond or do not respond at all.
Influence of Modification and Casting Technology on Structure of IN-713C Superalloy Castings
Authors: Binczyk F. , Cwajna J. , Gradoń P. , Mańka M. 
Published: September 2016

Abstract
The paper presents the results concerning impact of modification (volume and surface techniques), pouring temperature and mould temperature on stereological parameters of macrostructure in IN713C castings made using post-production scrap. The ability to adjust the grain size is one of the main issues in the manufacturing of different nickel superalloy castings used in aircraft engines. By increasing the grain size one can increase the mechanical properties, like diffusion creep resistance, in higher temperatures. The fine grained castings. on the other hand, have higher mechanical properties in lower temperatures and higher resistance to thermal fatigue. The test moulds used in this study, supplied by Pratt and Whitney Rzeszow, are ordinarily used to cast the samples for tensile stress testing. Volume modification was carried out using the patented filter containing cobalt aluminate. The macrostructure was described using the number of grains per mm2, mean grain surface area and shape index. Obtained results show strong relationship between the modification technique, pouring temperature and grain size. There was no significant impact of mould temperature on macrostructure.
3DP Technology for the Manufacture of Molds for Pressure Casting
Authors: Skorulski G. 
Published: September 2016

Abstract
The paper presents the use of rapid prototyping technology of three dimensional printing (3DP) to make a prototype shell casting mold. In the first step, for identification purposes, a mold was prepared to enable different alloys to be cast. All molds being cast were designed in a universal CAD environment and printed with the zp151 composite material (Calcium sulfate hemihydrate) with a zb63 binder (2-pyrrolidone). It is designated to be used to prepare colourful models presenting prototypes or casting models and molds. The usefulness of 3DP technology for use with copper alloys, aluminum and zinc was analyzed. The strength of the mold during casting was assumed as a characteristic comparative feature in the material resistance to high temperature, the quality of the resulting casting and its surface roughness. Casting tests were carried out in vacuum – pressure casting. The casting programs applied, significantly increased the quality of castings and enabled precise mold submergence. Significant improvement was noted in the quality compared to the same castings obtained by gravity casting.

Authors: Tarasiuk W. , Piwnik J. , Węgrzyn T. , Sieteski D. 
Published: September 2016

Abstract
This paper presents results of experimental research concerning the impact of an innovative method of micro-jet cooling on the padding weld performed with MIG welding. Micro-jet cooling is a novel method patented in 2011. It enables to steer the parameters of weld cooling in a precise manner. In addition, various elements which may e.g. enhance hardness or alter tribological properties can be entered into its top surface, depending on the applied cooling gas. The material under study was steel 20MnCr5, which was subject to the welding process with micro-jet cooling and without cooling. Nitrogen was used as a cooling gas. The main parameter of weld assessment was wear intensity. The tests were conducted in a tribological pin-on-disc type position. The following results exhibit growth at approximately 5% in wear resistance of padding welds with micro-jet cooling.

Quality Control in Production Processes
Authors: Prístavka Miroslav , Kotorová Martina , Savov Radovan 
Published: September 2016

Abstract
The tools for quality management are used for quality improvement throughout the whole Europe and developed countries. Simple statistics are considered one of the most basic methods. The goal was to apply the simple statistical methods to practice and to solve problems by using them. Selected methods are used for processing the list of internal discrepancies within the organization, and for identification of the root cause of the problem and its appropriate solution. Seven basic quality tools are simple graphical tools, but very effective in solving problems related to quality. They are called essential because they are suitable for people with at least basic knowledge in statistics; therefore, they can be used to solve the vast majority of problems.
Magic Realism, Minimalist Realism and the Figuration of the Tableau in Contemporary Hungarian and Romanian Cinema
Authors: Pieldner Judit 
Published: September 2016

AbstractThe paper surveys two modes of representation present in contemporary Hungarian and Romanian cinema, namely magic realism and minimalist realism, as two ways of rendering the “real” in the Central Eastern European geocultural context. New Hungarian Film tends to display narratives that share the features of what is generally assumed as being magic realist, accompanied by a high degree of stylization, while New Romanian Cinema is more attracted to creating austere, micro-realistic universes. The paper argues that albeit apparently being forking modes of representation that traverse distinct routes, magic realism and minimalist realism share a set of common elements and, what this study especially focuses on, converge in the preference for the tableau aesthetic. The paper examines the role of tableau compositions andtableaux vivantsin representative films of the Young Hungarian Film and the Romanian New Wave, namely Szabolcs Hajdu’sBibliothèque Pascal(2010) and Cristian Mungiu’sBeyond the Hills(După dealuri, 2012). An excessive use of the tableau can be detected in both films, with many thematic connections, in subtle interwovenness with female identiy and corporeality performed as a site of traumatic experiences, upon which (institutional, colonial) power relations are reinscribed. The tableau as a figuration of intermediality performs the tension between the sensation of the “real” and its reframed image, and proves especially suitable for mediating between low-key realism and highly stylized forms.1
When the Copywriter is the Protagonist. History and Intermediality in Pablo Larraín’sNo(2012)
Authors: Zucconi Francesco 
Published: September 2016

AbstractThrough films such asTony Manero(2008),Santiago 73,Post Mortem(2010), andNo(2012), the productions of Chilean director Pablo Larraín have focused on the historical and political themes that marked the last decades in the life of his country: the putsch against Salvador Allende and Augusto Pinochet’s dictatorship. This paper analyses the last film of the trilogy, dedicated to the 1988 Chilean national plebiscite and the communication battle between supporters of the “Yes” and “No” sides. Why does Larraín identify the copywriter René Saavedra as the main character of the film? And why does the film accord such importance to the advertising campaign in recounting the historical reality of democratic transition? How does the fictional film remediate the archival footage of the 1988 campaign? To answer these questions, this paper investigates the film as an audiovisual form of interpretation of historical events and film montage as an intermedial “authentication” of the archival documents relating to this traumatic past.
Accommodating the Mess: The Politics of Appropriation in It for Others (2013)
Authors: Blair Paula 
Published: September 2016

Abstract
In response to Chris Marker and Alain Resnais’s collaborative meditation on art and colonialism in Statues Also Die (1953), Duncan Campbell’s video installation It for Others (2013) takes a complex approach to presenting a Marxist criticism of the commoditization of art and culture. This article considers the intermedial and intertextual properties of It for Others as an example of convergence culture that transcends postmodern quotation and pastiche. While the film is apparently a bricolage of visual artefacts, it is in fact an intricately woven audiovisual essay concerned with the appropriation of not only colonized objects as its narration makes clear, but also of still images, moving images, written texts, sound samples, and the labour that produced them. The article examines how the film troubles notions of documentary realism and truth through its acts of appropriation that reflexively criticize the commercial appropriation and commoditization of artworks and histories. It also reflects on the film’s Marxist approach to related issues around authorship, ownership and access to artworks, particularly in the light of the film’s acknowledgement in prize culture.
Media-Morphosis. Intermediality, (Re-)Animation and the Medial Uncanny in Tsukamoto Shinya’sTetsuo: The Iron Man(1989)
Authors: Player Mark 
Published: September 2016

AbstractOperating self-sufficiently on the fringes of the Japanese film industry for almost his entire career, the work of independent filmmaker Tsukamoto Shinya1 is perhaps best-known for its uncompromising, musical freneticism, as well as its corporeal spectacle. However, Tsukamoto’s dynamic clashing of visual media signifiers, such as those of theatre and television (industries within which he also operated prior to his film career during the 1980s), and how these impact upon his reflexive cinematic style, has yet to be fully considered. Drawing on Laura Mulvey’s conception of the ‘uncanny’ in response to cinema’s potential to confuse animate and inanimate, as well as Tsukamoto’s own under-discussed background in experimental street theatre and television advertising production, this essay seeks to examine Tsukamoto’s unique method of stop motion photography within his signature, self-produced featureTetsuo: The Iron Man(1989). The intention is to show that these hyperbolic sequences instil not only an uncanniness in their live-action subjects, who are rendered inanimate then reanimated to form staccato, cyborg characters, but also a ‘medial uncanny’ that simultaneously emulates and subverts the qualities of a vast range of visual media, particularly television and its associated post-medial peripherals and artefacts.
Systèmes dynamiques algébriquement complètement intégrables et géométrie
Authors: Lesfari A. 
Published: September 2016

Résumé
In this paper I present the basic ideas and properties of the complex algebraic completely integrable dynamical systems. These are integrable systems whose trajectories are straight line motions on complex algebraic tori (abelian varieties). We make, via the Kowalewski-Painlevé analysis, a detailed study of the level manifolds of the system. These manifolds are described explicitly as being affine part of complex algebraic tori and the flow can be solved by quadrature, that is to say their solutions can be expressed in terms of abelian integrals. The Adler-van Moerbeke method’s which will be used is primarily analytical but heavily inspired by algebraic geometrical methods. We will also discuss several examples of algebraic completely integrable systems : Kowalewski’s top, geodesic flow on SO(4), Hénon-Heiles system, Garnier potential, two coupled nonlinear Schrödinger equations and Yang-Mills system.

Abstract
A procedure to estimate the local convergence radius for a Mann-type iteration is given in the setting of a finite dimensional space. In particular we obtain the estimation of radius for classical Newton method. Numerical experiments are presented showing the efficiency of the proposed procedure in comparison with other known methods. In some cases our procedure gives the maximum local convergence radius.
On the Local Convergence of an Eighth-order Method for Solving Nonlinear Equations
Authors: Argyros Ioannis K. , Kansal Munish , Kanwar V. 
Published: September 2016

Abstract
We present a local convergence analysis of an eighth-order method for approximating a locally unique solution of a non-linear equation. Earlier studies such as have shown convergence of these methods under hypotheses up to the seventh derivative of the function although only the first derivative appears in the method. In this study, we expand the applicability of these methods using only hypotheses up to the first derivative of the function. This way the applicability of these methods is extended under weaker hypotheses. Moreover, the radius of convergence and computable error bounds on the distances involved are also given in this study. Numerical examples are also presented in this study.
Higher-Order Geodesic Equations from Non-Local Lagrangians and Complex Backward-Forward Derivative Operators
Authors: El-Nabulsi Rami Ahmad 
Published: September 2016

AbstractStarting with an extended complex backwardforward derivative operator in differential geometry which is motivated from non-local-in-time Lagrangian dynamics, higher-order geodesic equations are obtained within classical differential geometrical settings. We limit our analysis up to the 2nd-order derivative where some applications are discussed and a number of features are revealed accordingly.
A note on the Miller-Tucker-Zemlin model for the asymmetric traveling salesman problem
Authors: Sawik T. 
Published: September 2016

Abstract
An enhancement of the Miller-Tucker-Zemlin (MTZ) model for the asymmetric traveling salesman problem is presented by introducing additional constraints to the initial formulation. The constraints account for ordering of boundary nodes as well as all successive nodes in the salesman tour. The enhanced MTZ subtour elimination constraints are computationally compared with the basic MTZ constraints and the version of MTZ lifted by Desrochers and Laporte. The proposed enhancement shows improved performance on a number of asymmetric TSPLIB instances.
Model predictive control of multilevel cascaded converter with boosting capability – a simulation study
Authors: Wiatr P. , Kazmierkowski M.P. 
Published: September 2016

Abstract
This paper presents a multilevel cascaded H-bridge 5-level converter with boosting capability. The standard solution for boosting voltage in power electronic devices is based on a DC-DC converter with a bulky inductor. However, inductor is a problematic component of a power electronic converter because usually it has to be individually designed and produced for every device and also because its size and weight do not allow for compact construction. This paper presents model predictive control (MPC) method that gives boosting capability for the presented converter. A novel contribution of this paper is the development of a predictive model of the converter and cost function enabling output current control and capacitor voltage balancing.
Prevalence of pseudonatremia in a clinical laboratory – role of the water content
Authors: Langelaan Marloes L.P. , Kamp Linda , Zandijk Eric , Raijmakers Maarten T.M. 
Published: September 2016

AbstractBackground:Sodium concentration is a frequently used marker to discriminate between differential diagnoses or for clinical follow-up. Pseudonatremia, as a result of indirect ion-selective electrode (ISE) measurements in automated chemistry analyzers, can lead to incorrect diagnosis and treatment. We investigated whether the estimated water content, based on total protein and lipid concentrations, can be used to reduce diagnoses of pseudonatremia.Methods:Indirect and direct ISE measurements of sodium were compared in blood samples from intensive care unit (ICU) (n = 98) and random non-ICU patients (n = 100). Differences between direct measurements using whole blood and lithium-heparin plasma were also determined. Water content, estimated by a linear combination of total protein and lipid concentrations, was used to correct indirectly measured sodium concentrations. The prevalence of pseudonatremia was evaluated in the ICU patient group.Results:An absolute difference of 3 mmol/L was observed between direct measurements using lithium-heparin plasma and whole blood, with higher concentrations in plasma. Additionally, we observed that differences between indirect and direct measurements displayed a linear relationship with the estimated water content. The prevalence of pseudohypernatremia after indirect measurements (32%) was reduced when measurements were corrected for water content (19%).Conclusions:In critically ill patients

Summary
Eggs enriched with n-3 fatty acids and natural pigments are desirable in human food chain due to numerous benefits for health. In this study, we investigated the effects of inclusion of co-extruded linseed and sunflower meal into laying hens’ diet and replacement of synthesized pigment with paprika and marigold flower as sources of natural pigments. Four hundred 18–wk-old Bovan laying hens divided in two groups (control and experiment) were fed for 12 weeks. Fatty acids and β-carotene were monitored every fourth week and successively analyzed. Significantly (p<0.05) increased content of α-linolenic acid in egg yolk in the experimental group in comparison to the control group was observed with addition of linseed, paprika and marigold in laying hens’ nutrition. Nearly the same tendency was observed in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) content. Supplementation of the co-extruded linseed and sunflower meal into laying hens’ diet demonstrated significantly (p<0.05) lower n-6/n-3 FA ratio in experimental group compared to control group. The obtained results showed that the synthetic pigment added to laying hens’ diet provided better pigmentation of egg yolks after one and two months of the feeding trial than paprika and marigold flower. The concentration of β-carotene in egg yolks increased in experimental group after three months of the treatment, and that was the first time that concentrations of β-carotene did not significantly (p < 0.05) differ among control and experimental group, which shows that paprika and marigold flower as sources of natural pigments can successfully replace synthetic pigment. We shall continue research in this field with other supplemented mixtures, as there are indices for other potential feed enhancements among oily seeds and herbs.

Published: September 2016

SummaryBy using biological assay in the laboratory were tested quality and impact of the water to the selected test plants: buckwheat (Fagopyrum esculentum) and cabbage (Brassica oleracea). Water was analyzed from two locations from the River Douro in Portugal. Physico-chemical analysis of general parameters in the water samples indicate that electrical conductivity and ammonium were detected in values exceeding MAC, according to Portuguese regulations on water quality. Also, in the analyzed samples of water in quantities that exceed the maximum allowable concentration values are: arsenic (As), selenium (Se), iron (Fe), magnesium (Mg). In tested samples several pharmaceuticals were detected. The obtained results indicate differences in tolerance of the test plants towards the quality of water. Physiological parameters (germination energy and germination) are not good indicators of water quality and more reliable can be considered some morphological traits (length, fresh and dry weight of root and shoot), that reacted in inhibition or stimulation, depending on water quality.
