Authors: Kurp P. , Mucha Z. , Tofil S. , Mulczyk K. 
Published: July 2016

Abstract
In this paper, the authors presented the research on laser formed construction bars made of C20 steel on the example of the T-shape. The CO2 TRUMPF TruFlow 6000 laser was used in the research. The influence of the laser treatment parameters (the power and speed of the heat source) on the volume of the bend angle, structure and properties of the elements (hardness and tensile strength) was examined. On the basis of the results obtained from the conducted experiments, the authors suggested a way of selecting treatment parameters so that the element should meet the strength assumptions at the allowable time of its implementation.
An Analysis of Laser-Welded Nicr-Ir and Nicr-Pt Micro Joints on Spark Plug Electrodes in Biogas-Fuelled Engines
Authors: Grabas B. , Tofil Sz. , Napadłek W. 
Published: July 2016

Abstract
The paper deals with the laser beam welding of tips to central and side spark plug electrodes made of a nickel-chromium alloy. The tips attached to the central electrodes were made from a solid iridium wire 0.8 mm in diameter and 2 mm in length, while the tips connected to the side electrodes were made from a platinum wire 1.5 mm in diameter and 0.25 mm in thickness. In both cases, accurate positioning of the tips was required before they were resistance welded to the electrodes. Then, a fillet weld was produced with an Nd:YAG laser using single, partly overlapping conductive pulses. The laser welding was performed at different laser power levels and pulse durations. Metallographic sections of the joints were prepared to observe changes in the microstructure and determine their correlation with the changes in the process parameters. The results were used to select appropriate welding parameters for the materials joined. The microscopic analysis indicated welding imperfections such as micro cracks at the interface between the elements joined. The tips welded to the spark plug electrodes can help extend the service life of spark plugs in highly corrosive environments.
Experimental – Numerical Analysis of Stress State in Front of the Crack Tip of Modified and Unmodified G17CrMo5-5 Cast Steel by Rare Earth Metals in a Brittle-Ductile Transition Region
Authors: Dzioba I. , Pala R. , Kasinska J. 
Published: July 2016

Abstract
In the paper presented experimental data and numerical analysis of stress distribution in front of the crack of two melts of low-alloy G17CrMo5-5 cast steel-modified (M) by rare earth metals and original, unmodified (UM) in the temperature range, according to the brittle-ductile transition region. Experimental tests include determination of the tensile properties and fracture toughness characteristics for the UM and M cast steel. Numerical analysis includes determination of stress distribution in front of the crack at the initial moment of the crack extension. In the numerical computations, experimentally tested specimens SEN(B) were modeled. The true stress-strain curves for the UM and M cast steel were used in the calculation. It was shown that the maximum of the opening stresses at the initial moment of the crack extension occurs in the axis of the specimens and reaches similar level of about 3.5σ0 for both UM and M cast steel. However, the length of the critical distance, measured for stress level equal 3σ0, is great for the M in comparison to the UM cast steel. Also was shown that the UM cast steel increased the level of the stress state triaxiality parameters that resulted in a decrease of fracture toughness.

Manufacturing, Microstructure and Corrosion Resistance of Electrophoretically Deposited SiO2 and Ni/SiO2 Coatings On X2CrNiMo17–12–2 Steel
Authors: Ratajski T. , Kalemba-Rec I. , Dubiel B. 
Published: July 2016

Abstract
The SiO2 and Ni/SiO2 coatings were electrophoretically deposited on X2CrNiMo17-12-2 steel using ethanol-based suspensions of the SiO2 and Ni powders. The influence of the zeta potential and concentration of the suspensions, the applied voltage and deposition time on the quality of the coatings was studied. Microstructure of the plan-view and cross sections of the coatings was investigated using scanning electron microscopy. The plan-view images revealed the uniform microstructure of the coatings with sporadically observed cracks, pores as well SiO2 and Ni agglomerates. On the cross-sections, the Cr2O3 layer, resulted from oxidation of the substrate during sintering of the coatings was observed. The polarization tests have shown that SiO2 and Ni/SiO2 coatings improve the corrosion resistance of the X2CrNiMo17-12-2 steel in 3.5% NaCl aqueous solution.
Influence of Solution and Aging Treatment Conditions on the Formation of Ultrafine-Grained Structure of CuFe2 Alloy Processed by Rolling with Cyclic Movement of Rolls
Authors: Urbańczyk-Gucwa A. , Radwański K. , Rodak K. 
Published: July 2016

Abstract
The effect of second phase particles on grain refinement in CuFe2 alloy has been investigated by using rolling with the cyclic movement of rolls (RCMR) method. Two different population of second phase particles of Fe: coherent, about 10 nm in diameter and about 100 nm in size were obtained by applying aging treatment followed at 500°C for 2 h and at 700°C for 24 h respectively. In addition, solution treated samples were deformed by RCMR method at the same parameters. The microstructures of the CuFe2 alloy were analyzed using light microscope (LM), electron backscattered diffraction (EBSD) microscope technique and scanning transmission electron microscope (STEM). The presence of high-density of coherent Fe particles in the matrix inhibits recovery process and in the result obtained grain/subgrain boundaries have diffused character and are weakly visible. The largest particles which are not coherent with the matrix act as an effective barrier against the boundary motion.
Simulation of imperfections in plastic lenses – transferring local refractive index changes into surface shape modifications
Authors: Arasa Josep , Pizarro Carles , Blanco Patricia 
Published: July 2016

Abstract
Injection molded plastic lenses have continuously improved their performance regarding optical quality and nowadays are as usual as glass lenses in image forming devices. However, during the manufacturing process unavoidable fluctuations in material density occur, resulting in local changes in the distribution of refractive index, which degrade the imaging properties of the polymer lens. Such material density fluctuations correlate to phase delays, which opens a path for their mapping. However, it is difficult to transfer the measured variations in refractive index into conventional optical simulation tool. Thus, we propose a method to convert the local variations in refractive index into local changes of one surface of the lens, which can then be described as a free-form surface, easy to introduce in conventional simulation tools. The proposed method was tested on a commercial gradient index (GRIN) lens for a set of six different object positions, using the MTF sagittal and tangential cuts to compare the differences between the real lens and a lens with homogenous refractive index, and the last surface converted into a free-form shape containing the internal refractive index changes. The same procedure was used to reproduce the local refractive index changes of an injected plastic lens with local index changes measured using an in-house built polariscopic arrangement, showing the capability of the method to provide successful results.

Abstract
The current study presents some aspects of syphilis in the Balkan Peninsula from the 19th century until the Interwar. Ever since the birth of modern Balkan States (Greece, Bulgaria, Turkey and Serbia), urbanization, poverty and the frequent wars have been considered the major factors conducive to the spread of syphilis. The measures against sex work and sexually transmitted diseases (STDs) were taken in two aspects, one medical and the other legislative. In this period, numerous hospitals for venereal diseases were established in the Balkan countries. In line with the international diagnostic approach and therapeutic standards, laboratory examinations in these Balkan hospitals included spirochete examination, Wassermann reaction, precipitation reaction and cerebrospinal fluid examination. Despite the strict legislation and the adoption of relevant laws against illegal sex work, public health services were unable to curb the spread of syphilis. Medical and social factors such as poverty, citizen’s ignorance of STDs, misguided medical perceptions, lack of sanitary control of prostitution and epidemiological studies, are highlighted in this study. These factors were the major causes that helped syphilis spread in the Balkan countries during the 19th and early 20th century. The value of these aspects as a historic paradigm is diachronic. Failure to comply with the laws and the dysfunction of public services during periods of war or socioeconomic crises are both factors facilitating the spread of STDs.
A Prospectus of Tenomodulin
Authors: Alexandrov Vesselin P. , Naimov Samir I. 
Published: July 2016

AbstractTenomodulin is a type II transmembrane glycoprotein that can regulate growth of tendon. The human tenomodulin encoding gene is mapped to Х chromosome and encodes a polypeptide consisting of 317 alpha amino acids. The protein is located on the cell surface as N-glycosylated or non-N-glycosylated polypeptide with molecular mass of 45 and 40 kDa, respectively. The molecule consists of three domains and a short cytoplasmic tail at N-terminus. Tenomodulin is predominantly expressed in dense connective hypovascularized tissues such as tendons, skeletal muscle epimysium, and ligaments. Furthermore, tenomodulin is an efficient marker of tenocyte differentiation and plays an important role in the regulation of tenocyte proliferation, tendon development, and angiogenesis inhibition. A number of tenomodulin gene polymorphisms have been recently associated with a risk of obesity, diabetes, systemic immune mediators, cholesterol levels, Alzheimer disease, and age-related macular degeneration. Tenomodulin is involved in cell adhesion, determination of cell morphology, cell aging and bone mineral density. It is expected to play an important role in tendon recovery, tendon tissue engineering, anti-tumor therapy, treatment of chordal disruption, and remodeling of extracellular matrix.

AbstractEarly clearance of leukemic cells during induction therapy of childhood acute lymphoblastic leukemia (ALL) is a basis for treatment optimization. Currently, the most widely used methods for the detection of minute residual malignant cells in the bone marrow and/or peripheral blood, minimal residual disease (MRD), are PCR and flow cytometry (FCM). Immunophenotypic modulation (IM) is a well known factor that can hamper the accurate FCM analysis.Aim: To report the IM detected by 8-color FCM during the BFM-type remission induction in 24 consecutive MRD-positive samples of children with B-cell precursor ALL and the possible implications for MRD detection.Patients and methods: Between 2010 and 2012 we prospectively followed up the MRD on days 15 and 33 of induction treatment in bone marrow (BM) samples and on day 8 in peripheral blood (PB). The IM was assessed by comparative analyses of the changes in the mean fluorescence intensity of 7 highly relevant antigens expressed by the leukemic cells and normal B-lymphocytes.Results: IM occurred, to different extents, in all analyzed day 15 BM and in most day 33 BM samples. Statistically significant changes in the MFI-levels of four CDs expressed by the leukemic blasts were observed: downmodulation of CD10, CD19 and CD34 and upmodulation of CD20. No changes in the expression of CD38, CD58 and CD45 were noticed.Conclusions: Measuring the MRD by standardized 8-color flow cytometry helps improve the monitoring of the disease, leading to better therapeutic results. However, the IM of the different antigens expressed by the leukemic blasts should be taken into consideration and cautiously analyzed.

Abstract
The present study deals with two dimensional deformation, due to internal heat source in a thermoelastic microelongated solid. A mechanical force is applied along the interface of elastic half space and thermoelastic microelongated half space. The problem is in the context of Green Lindsay (GL) theory. The analytic expressions for displacement component, normal force stress, temperature distribution and microelongation have been derived. The effect of internal heat source and microelongation on the derived components have been depicted graphically.
Toward a formal model of semantic change: A neo-Reichenbachian approach to the development of the Vedic past tense system
Authors: Dahl Eystein 
Published: July 2016

Abstract
This paper explores some ways in which a neo-Reichenbachian time-relational framework can be applied to diachronic data. The target language of this study is Vedic Sanskrit, the language of the sacred texts of Hinduism. The main focus of the paper concerns the evolution of the Vedic past tense system, which at the beginning of the Vedic tradition is aspect-based and later develops into a system where temporal remoteness and evidentiality distinctions determine the distribution of the past tense categories. This language therefore offers a particularly intriguing data set for exploring the diachronic relationship between aspect, proximal tense and evidentiality, a field of diachronic semantics which has only received limited attention in the research literature.
A Mixed Shooting – Harmonic Balance Method for Unilaterally Constrained Mechanical Systems
Authors: Schreyer Frederic , Leine Remco I. 
Published: July 2016

Abstract
In this paper we present a mixed shooting – harmonic balance method for
large linear mechanical systems on which local nonlinearities are imposed. The standard
harmonic balance method (HBM), which approximates the periodic solution
in frequency domain, is very popular as it is well suited for large systems with
many degrees of freedom. However, it suffers from the fact that local nonlinearities
cannot be evaluated directly in the frequency domain. The standard HBM performs
an inverse Fourier transform, then calculates the nonlinear force in time domain and
subsequently the Fourier coefficients of the nonlinear force. The disadvantage of
the HBM is that strong nonlinearities are poorly represented by a truncated Fourier
series. In contrast, the shooting method operates in time-domain and relies on numerical
time-simulation. Set-valued force laws such as dry friction or other strong
nonlinearities can be dealt with if an appropriate numerical integrator is available.
The shooting method, however, becomes infeasible if the system has many states.
The proposed mixed shooting-HBM approach combines the best of both worlds.
From gold nanoparticles to luminescent nano-objects: experimental aspects for better gold-chromophore interactions
Authors: Navarro Julien R.G. , Lerouge Frederic 
Published: July 2016

Abstract
Gold nanoparticles have been the center of interest for scientists since many decades. Within the last 20 years, the research in that field has soared with the possibility to design and study nanoparticles with controlled shapes. From spheres to more complex shapes such as stars, or anisotropic architectures like rods or bipyramids, these new systems feature plasmonic properties making them the tools of choice for studies on light-matter interactions. In that context, fluorescence quenching and enhancement by gold nanostructures is a growing field of research. In this review, we report a non-exhaustive summary of the synthetic modes for various shapes and sizes of isotropic and anisotropic nanoparticles. We then focus on fluorescent studies of these gold nano-objects, either considering “bare” particles (without modifications) or hybrid particles (surface interaction with a chromophore). In the latter case, the well-known metal-enhanced fluorescence (MEF) is more particularly developed; the mechanisms of MEF are discussed in terms of the additional radiative and non-radiative decay rates caused by several parameters such as the vicinity of the chromophore to the metal or the size and shape of the nanostructures.
„Körper Wissen“ – Körpermacht
Authors: Koch Anne 
Published: July 2016

Abstract
In jüngster Zeit ist ein besonderer Diskurs um „Körperwissen“ auszumachen, auf dessen Grundlage eine bislang ungekannte Regulierung von Subjekten ermöglicht wird: Sie besetzt den „ inneren Körper“ und rationalisiert Akteure zu wissenden Körpern. Das ist folgenreich. Von dem Moment an, in dem Körpern ein Wissen zugeschrieben wird, muss dieses wieder optimiert werden und fällt unter all die Formen neoliberaler Regierungsausübung, wie wir sie bereits kennen. Dieser jüngste populäre Diskurs hat Wurzeln im (körper- und sport-)soziologischen Diskurs als auch in der theosophisch-esoterischen postdualistischen und postmaterialistischen Anthropologie feinstofflicher Körper. Neuartige säkularistische wie spirituelle Praktiken können an Körperwissen nun ansetzen und entfalten eine umso mächtigere Regulierung, wenn sie in big data eingespeist werden wie bei körperüberwachenden digitalen Apps zur Achtsamkeit. Vor diesem Hintergrund wird für eine sorgfältige Kritik des Diskurses Körperwissen argumentiert.
Der Körper in der Askese bei Evagrios Pontikos und Philoxenos von Mabbug
Authors: Stellmacher Alexandra 
Published: July 2016

AbstractIm Vergleich der Schriften zweier spätantiker christlicher Autoren werden in diesem Beitrag ihre Vorstellungen von Askese und der Rolle, die der Körper in der asketischen Übung spielt, kontrastierend gegenübergestellt. Ihre Ansichten zu Eschatologie und Anthropologie sowie zu den Wegen, die zur Erlangung eines , Wissens von Gott‘ durch Praxis führen, haben maßgeblichen Einfluss auf das in den Texten transportierte Körperwissen und asketische Übungswissen. Evagrios Pontikos schreibt im 4. Jahrhundert in der ägyptischen Wüste aus eigener asketischer Erfahrung heraus und macht mithin ein selbst erlangtes Übungswissen als schriftliches Anleitungswissen zugänglich. Bei Philoxenos von Mabbug, der im 5. Jahrhundert in Syrien lebt, ist die Annahme, dass das von ihm verschriftlichte Wissen auf eigener Übung beruht, nicht gesichert.
Vom Körperwissen und Wissenskörper zum Wissenskorpus
Authors: Lehmhaus Lennar 
Published: July 2016

AbstractIm Kontrast zu griechisch-römischen Medizintraditionen finden sich in talmudischen Texten keine umfassenden Theorien zur menschlichen Physiologie und Anatomie, sondern nur einschlägiges im gesamten Traditionskorpus verstreutes Körperwissen. Analyse und Rekonstruktion einer „Talmudischen Anatomie oder Physiologie“ muss deren komplexe kulturell-kontextuelle und diskursive Einbettung beachten. Die Studie untersucht die rabbinische Vermittlung solchen Wissens durch metaphorische Beschreibung körperlicher Strukturen und Prozesse. Kulturspezifische Verwendungsmuster und diskursive Strategien der Metaphorisierung geben dabei Aufschluss über den Nexus zwischen Wissen vom Körper, dem Wissenskörper des Gelehrten und dem Wissenskorpus der Tradition.
Wissen als asketische Körperpraxis bei Mahima Dharma
Authors: Guzy Lidia 
Published: July 2016

Abstract
Der Artikel thematisiert den Körper als Medium des spirituellen Wissens und der Erkenntnisvermittlung von Mahima Dharma – einer neueren asketischen Bewegung des östlichen Indiens. Anhand indigener Konzepte von Wissen und Erleuchtung (gyan) wird spirituelle Erkenntnis im Sinne eines esoterischen asketischen Wissens analysiert. Esoterisches (exklusives) asketisches Wissen in der neueren asketischen Tradition Mahima Dharma entsteht nur mittels des spezialisierten Körperwissens eines Asketen oder Laien. Die richtigen Werte des Lebens für Asketen und Laien werden nur mittels einer disziplinierten Körperpraxis verkörpert. Der Artikel basiert auf langwierigen Feldforschungen unter Asketen der Mahima Dharma-Religion des östlichen Indiens.
Zwischen Bewahrung und Erneuerung
Authors: Klinge Antje 
Published: July 2016

AbstractDer Körper wird in der Sportwissenschaft sowohl aus naturwissenschaftlichen als auch sozial- und geisteswissenschaftlichen Perspektiven thematisiert. Dabei stellt das Wissen über den Körper den Kern sportmedizinischer, trainings- und bewegungswissenschaftlicher Forschung und Theoriebildung dar. Die hier gewonnenen Erkenntnisse über den Körper als funktions- und leistungsfähiges Organ liefern die Grundlage für Theorien der motorischen Entwicklung und des Bewegungslernens. Dass der Körper selbst über ein Wissen verfügt, das die Wahrnehmungs-, Denk- und Handlungsweisen des Menschen bestimmt, wird selten diskutiert. Im Beitrag wird diese in der Sportwissenschaft vernachlässigte Dimension aus leibphänomenologischer sowie körper- und kultursoziologischer Perspektive betrachtet und im Hinblick auf ein Lernen und Verstehen mit dem Körper erörtert. Damit wird der Körper als Reflexions- und Erkenntnisorgan ins Spiel gebracht.
Embodiment, Metapher und Filmrezeption: Körperwissen in „Oh Boy“ (D 2012)
Authors: Buchholz Michael , Hamburger Andreas 
Published: July 2016

AbstractAus psychoanalytischer Perspektive interpretieren die Autoren den Kultfilm „Oh Boy“ (D 2012) von Jan-Ole Gerster zum einen in Bezug auf das Körperwissen, das im fortwährend transformierten Konzept-, Konversations- und Metapherngerüst der Sprache kondensiert ist, zum anderen auf die Steuerung körperlich-affektiver Prozesse der Filmrezeption in der Mise en scène. Der Film ist ein Meister- und Lehrstück des Umdenkens, eine Momentaufnahme der in die Alltagstristesse eines Jugendlichenlebens im heutigen Berlin eingeschriebenen Aussparung der Nazigeschichte. Wie kann das entweder abgespaltene oder totinszenierte Geschichtswissen lebendig werden? Die Autoren zeigen, mit welch subtilen sprachlichen und filmischen Mitteln der Film Wissen vom Kopf auf die Füße stellt und welche Rolle(n) der Körper dabei spielt.
