The Standardised Mensendieck Test as a tool for evaluation of movement quality in patients with nonspecific chronic low back pain
Authors: Kaarbø Mette Bøymo , Haugstad Gro Killi , Stubhaug Audun , Wojniusz Slawomir 
Published: April 2018

Abstract

Background and aims:
Nonspecific chronic low back pain is a multifactorial biopsychosocial health problem where accurate assessments of pain, function and movement are vital. There are few reliable and valid assessment tools evaluating movement quality, hence the aim was to investigate nonspecific chronic low back pain patients’ movement patterns with the Standardised Mensendieck Test.

Methods:
Twenty patients (mean age=41, SD=9.02) with nonspecific chronic low back pain were examined with the Standardised Mensendieck Test whilst being videotaped and compared with 20 healthy controls. A physiotherapist, blinded to participant’s group belonging, scored Standardised Mensendieck Test videos according to the standardised manual. Associations between movement quality, fear of movement and re(injury) i.e. kinesiophobia and pain intensity were also investigated.

Results:
Patients scored significantly poorer than the controls in all 5 Standardised Mensendieck Test domains (p<0.001). The biggest difference was observed with regard to movement pattern domain. In women we also found a difference in the respiration pattern domain.

Conclusions:
The Standardised Mensendieck Test was able to detect significant differences in quality of movement between patients and healthy controls. These results indicate that the Standardised Mensendieck Test may be a valuable examination tool in assessment and treatment of nonspecific chronic low back pain patients. Further, longitudinal studies should investigate whether poor movement and respiration patterns are important factors in nonspecific chronic low back pain, e.g. as predictors and/or mediators of therapeutic effects.
Postsocialist Informal Urbanism between Creativity and Power. Notes on Four Projects from Romania
Authors: Văetişi Şerban 
Published: April 2018

Abstract
The author illustrates squatting, do-it-yourself urbanism, creative re-appropriation of public space, guerrilla gardening, and artistic occupy-type intervention as forms and evolutions of informal urbanism. By interpreting examples observed in two postsocialist Romanian cities the author comments on the thin boundary between informal and authorized urbanism, and between creativity and power; he interrogates also the key matter of access to the city, with its regulations, resources, and potentialities. His perspective implies an empirical and ethnographic approach to informality, which is analysed in the contexts of privatization logics, especially in relation to the reconfiguration of the public and the private which is so specific to postsocialist transformations. The contrast between grass-roots responses and official projects is seen as decisive in understanding strategies of representations, control of resources, and capital accumulation. Additionally the author suggests the relevance of theorizing such postsocialist urban processes in fruitful but critical comparison with other non-Western forms of urbanism, notably postcolonial ones.
‘And When the Heart is Sick, the Whole Body is Sick.’ Repairing the Person and the Urban Fabric through Everyday Sufi Ethics in Postwar Sarajevo
Authors: Kostadinova Zora 
Published: April 2018

Abstract
The author explores how the ritual religious practice of Sufism and the charismatic leadership of the sheikh play a role in ethical self-making and community-building in Sarajevo, Bosnia-Herzegovina. She traces how the Sufi concept of adab, or proper dervish conduct, represents at once a transcendent relationship with the Divine and urban civility. The author argues that Sufi practices in the care for the self represent an authentic response to the postwar and postsocialist ethical demand in the city of restoring urban social relationships. The processes analysed here reflect wider changes in what constitutes an Islamic authority in post-Yugoslav Bosnia, and the impact this has on the ongoing local debate on Islam as discursive tradition.
Multivariate Kalibrationsverfahren für einen nicht-dispersiven Infrarotsensor zur Ölzustandsüberwachung in Verbrennungsmotoren

Published: April 2018

Zusammenfassung
In diesem Beitrag wird die Kalibration eines kompakten optischen Sensors für die Online-Ölzustandsüberwachung in Verbrennungsmotoren vorgestellt. Der Sensor basiert auf dem Prinzip der nicht-dispersiven Infrarotspektroskopie (NDIR-Spektroskopie) und misst die Absorption in sieben verschiedenen Spektralbereichen. Mit Hilfe multivariater Regressionsmethoden werden lineare Modelle erstellt, die den Zusammenhang zwischen infraroter Absorption und wichtigen Ölzustandsparametern, wie beispielsweise Wassergehalt, Oxidation, Sulfation und Basenzahl, beschreiben. Die Validierung der Modelle anhand eines Datensatzes von Gebrauchtölproben aus unterschiedlichen Anwendungen zeigt eine gute Übereinstimmung mit Referenzwerten aus einer Laboranalyse. Durch den Einsatz von Kalibrationstransferverfahren können die erstellten Regressionsmodelle auf einem zweiten Sensor gleicher Bauart angewendet werden, wobei sich die Prädiktionsgüte nur geringfügig verschlechtert.
Metaphor, discourse dynamics and register: applications to written descriptions of mental health problems
Authors: Knapton Olivia , Rundblad Gabriella 
Published: April 2018

Abstract
Discursive approaches to metaphor recognize that different social contexts and discourse activities will influence metaphor use. Using a descriptive text written by a participant with obsessive-compulsive disorder (OCD) as a case study, we demonstrate how, in a research context, metaphors do not only serve a representational function but they can also build relationships between the researcher and the participant, create a persuasive piece of writing and construct multiple identities. Through an analysis of metaphors and their surrounding, non-metaphorical co-text, it is thus argued that studies exploring metaphor in elicited research data need to integrate considerations of the research context into their analyses to a greater extent. We also show how a discourse dynamics approach to metaphor can be combined with a systemic-functional approach to register in order to capture both the discursive functions of metaphors and their emergence as the text progresses.
Investigation of Leading Edge Tubercles with Different Wavelengths in an Annular Compressor Cascade

Published: April 2018

Abstract
Humpback whales possess bumpy tubercles on the leading edge of their flippers. Due to these leading edge tubercles, whales are able to produce high degree of maneuverability. Inspired by the flippers, this paper applies sinusoidal-like tubercles to the leading edge of blades in an annular compressor cascade, and presents a numerical investigation to explore the effects of tubercles with the aim of controlling the corner separation and reducing losses. Steady 3D RANS simulations are performed to investigate the aerodynamic performance and behavior of the corner separation in compressor cascades with and without leading edge tubercles. A crucial geometry parameter of the tubercles, wavelength, is varied to obtain different configurations. Results show that a smaller wavelength (more wave number) corresponds to a larger loss reduction and the maximum loss reduction reaches to 46.0%. Also, it is found that leading edge tubercles result in a stall delay and the maximum stall angle improvement reaches to 28.1%. Flow visualizations show that leading edge tubercles could induce the formation of counter-rotating streamwise vortices. The interaction between the streamwise vortices and corner separation is thought to be the primary flow mechanism generated by leading edge tubercles in an annular compressor cascade.
Wittgenstein’s Ambivalent Attitude toward Science and Culture
Authors: Somavilla Ilse 
Published: April 2018

Abstract:Wittgenstein’s ambivalent attitude toward science (and philosophy) can be observed as early as in the Tractatus – both in the preface and toward the end, e. g. on 6.52, 6.54 and also implicitly inherent in his final sentence “Whereof one cannot speak, thereof one must be silent.”
Thus, despite his analytical method and apparently high appreciation of science, he was aware of its limits – as well as of its dangers. This awareness becomes increasingly obvious in the course of the later years, among others marked by a shift from analysis to description and a turning to other ways of knowledge than scientific ones: Ways of showing instead of saying viz. verbal and scientific explanations. These alternatives he saw in literature, art and music.
However, even as concerns these fields, he sometimes holds a critical attitude toward culture, above all within the development of the civilization of his century. His resentment of the gradual moral and intellectual decline at the turn of the 20th century leads to a highly suspicious attitude toward any progress in the fields of culture and science, which he clearly expresses in his preface to the Philosophical Remarks, distancing himself from the so-called typical western scientist, whose spirit he considers “alien & uncongenial’ to his”.

Voices from the Threshold in Attia Hosain’s Sunlight on a Broken Column
Authors: Sachdev Tanvir 
Published: April 2018

Abstract
Multiple patriarchies have attempted to circumscribe women within the private sphere, encrypting their identities with broader definitions of class, caste, community, and nation. Malashri Lal in The Law of the Threshold has suggested the threshold – a real as well as symbolic bar that patriarchies place before women – as a tool for literary criticism. The paper takes up Attia Hosain’s Sunlight on a Broken Column to examine negotiations of women from varying classes and communities with the dynamics of the threshold and their positioning inside, on, and outside the threshold. Issues of gender and the transgression of the controls and harness upon women’s sexuality are examined with the intersecting paradigms of class, community, and the changing face of the nation. The forces and anxieties emanating from opposing pulls of the inner world of the traditional order and the outer modern Western world that pre-empt the move outside the threshold are also traced against a colonial backdrop.
Melioration of Optical and Electrical Performance of Ga-N Codoped ZnO Thin Films
Authors: Narayanan Nripasree , Deepak N. K. 
Published: April 2018

Abstract
Transparent and conducting p-type zinc oxide (ZnO) thin films doped with gallium (Ga) and nitrogen (N) simultaneously were deposited on glass substrates by spray pyrolysis technique. Phase composition analysis by X-ray diffraction confirmed the polycrystallinity of the films with pure ZnO phase. Energy dispersive X-ray analysis showed excellent incorporation of N in the ZnO matrix by means of codoping. The optical transmittance of N monodoped film was poor but got improved with Ga-N codoping and also resulted in the enhancement of optical energy gap. Hole concentration increased with codoping and consequently, lower resistivity and high stability were obtained.

Si2O7: xPr3+ were successfully prepared by the high-temperature solid-state method. The crystal structure, morphology, and optical spectrum were characterised by X-ray diffraction (XRD), scanning electron microscopy (SEM), and spectroscopy, respectively. The XRD patterns of the samples indicate that the crystal structure is monoclinic symmetry. The SEM shows that the selected sample has good crystallinity although its appearance is irregular and scalelike. The peak of the excitation spectrum of the sample is located at around 449 nm, corresponding to 3H4→3P2 transition of Pr3+. The peak of the emission spectrum of the sample is situated at around 612 nm which is attributed to 3P0→3H6 transition of Pr3+, and the colour is orange-red. The optimum concentration for Pr3+ replaced Ca2+ sites in Ca3Si2O7: Pr3+ is 0.75 mol%. The lifetime (8.48 μs) of a typical sample (Ca2.9925Pr0.0075)Si2O7 is obtained.

Abstract
Fifteen pyrrole alkaloids were isolated from the Red Sea marine sponge Stylissa carteri and investigated for their biological activities. Four of them were dibrominated [(+) dibromophakelline, Z-3-bromohymenialdisine, (±) ageliferin and 3,4-dibromo-1H-pyrrole-2-carbamide], nine compounds were monobrominated [(−) clathramide C, agelongine, (+) manzacidin A, (−) 3-bromomanzacidin D, Z-spongiacidin D, Z-hymenialdisine, 2-debromostevensine, 2-bromoaldisine and 4-bromo-1H-pyrrole-2-carbamide)] and finally, two compounds were non-brominated derivatives viz., E-debromohymenialdisine and aldisine. The structure elucidations of isolated compounds were based on 1D & 2D NMR spectroscopic and MS studies, as well as by comparison with literature. In-vitro, Z-spongiacidin D exhibited a moderate activity on (ARK5, CDK2-CycA, CDK4/CycD1, VEGF-R2, SAK and PDGFR-beta) protein kinases. Moreover, Z-3-bromohymenialdisine showed nearly similar pattern. Furthermore, Z-hymenialdisine displayed a moderate effect on (ARK5 & VEGF-R2) and (−) clathramide C showed a moderate activity on AURORA-A protein kinases. While, agelongine, (+) manzacidin A, E-debromohymenialdisine and 3,4-dibromo-1H-pyrrole-2-carbamide demonstrated only marginal inhibitory activities. The cytotoxicity study was evaluated in two different cell lines. The most effective secondary metabolites were (+) dibromophakelline and Z-3-bromohymenialdisine on L5178Y. Finally, Z-hymenialdisine, Z-3-bromohymenialdisine and (±) ageliferin exhibited the highest cytotoxic activity on HCT116. No report about inhibition of AURORA-A and B by hymenialdisine/hymenialdisine analogs existed and no reported toxicity of ageliferin existed in literature.

Published: April 2018

Abstract
The effciency of organic solar cells is not only determined by their absorber system, but also strongly dependent on the performance of numerous interlayers and charge transport layers. In order to establish new custom-made materials, the study of structure-properties relationships is of great importance. This publication examines a series of naphthalenetetracarboxylic diimide molecules (NTCDI) with varying side-chain length intended for the use as n-dopable electron transport materials in organic solar cells. While all compounds basically share very similar absorption spectra and energy level positions in the desired range, the introduction of alkyl chains has a large impact on thin film growth and charge transport properties: both crystallization and the increase of conductivity by molecular doping are suppressed. This has a direct influence on the series resistance of corresponding solar cells comprising an NTCDI derivative as electron transport material (ETM) as it lowers the power conversion efficiency to ≪1%. In contrast, using the side-chain free compound it is possible to achive an efficiency of 6.5%, which is higher than the efficiency of a comparable device comprising n-doped C60 as standard ETM.
Catalysis by Metallic Nanoparticles in Solution: Thermosensitive Microgels as Nanoreactors
Authors: Roa Rafael , Angioletti-Uberti Stefano , Lu Yan , Dzubiella Joachim , Piazza Francesco , Ballauff Matthias 
Published: April 2018

Abstract
Metallic nanoparticles have been used as catalysts for various reactions, and the huge literature on the subject is hard to overlook. In many applications, the nanoparticles must be affixed to a colloidal carrier for easy handling during catalysis. These “passive carriers” (e.g. dendrimers) serve for a controlled synthesis of the nanoparticles and prevent coagulation during catalysis. Recently, hybrids from nanoparticles and polymers have been developed that allow us to change the catalytic activity of the nanoparticles by external triggers. In particular, single nanoparticles embedded in a thermosensitive network made from poly(N-isopropylacrylamide) (PNIPAM) have become the most-studied examples of such hybrids: immersed in cold water, the PNIPAM network is hydrophilic and fully swollen. In this state, hydrophilic substrates can diffuse easily through the network, and react at the surface of the nanoparticles. Above the volume transition located at 32°C, the network becomes hydrophobic and shrinks. Now hydrophobic substrates will preferably diffuse through the network and react with other substrates in the reaction catalyzed by the enclosed nanoparticle. Such “active carriers”, may thus be viewed as true nanoreactors that open new ways for the use of nanoparticles in catalysis. In this review, we give a survey on recent work done on these hybrids and their application in catalysis. The aim of this review is threefold: we first review hybrid systems composed of nanoparticles and thermosensitive networks and compare these “active carriers” to other colloidal and polymeric carriers (e.g. dendrimers). In a second step we discuss the model reactions used to obtain precise kinetic data on the catalytic activity of nanoparticles in various carriers and environments. These kinetic data allow us to present a fully quantitative comparison of different nanoreactors. In a final section we shall present the salient points of recent efforts in the theoretical modeling of these nanoreactors. By accounting for the presence of a free-energy landscape for the reactants’ diffusive approach towards the catalytic nanoparticle, arising from solvent-reactant and polymeric shell-reactant interactions, these models are capable of explaining the emergence of all the important features observed so far in studies of nanoreactors. The present survey also suggests that such models may be used for the design of future carrier systems adapted to a given reaction and solvent.

Published: April 2018

Abstract
Effects of interfaces on hydrogen-bonded liquids play major roles in nature and technology. Despite their importance, a fundamental understanding of these effects is still lacking. In large parts, this shortcoming is due to the high complexity of these systems, leading to an interference of various interactions and effects. Therefore, it is advisable to take gradual approaches, which start from well designed and defined model systems and systematically increase the level of intricacy towards more complex mimetics. Moreover, it is necessary to combine insights from a multitude of methods, in particular, to link novel preparation strategies and comprehensive experimental characterization with inventive computational and theoretical modeling. Such concerted approach was taken by a group of preparative, experimentally, and theoretically working scientists in the framework of Research Unit FOR 1583 funded by the Deutsche Forschungsgemeinschaft (German Research Foundation). This special issue summarizes the outcome of this collaborative research. In this introductory article, we give an overview of the covered topics and the main results of the whole consortium. The following contributions are review articles or original works of individual research projects.
Anisotropy of Structure and Optical Properties of Self-Assembled and Oriented Colloidal CdSe Nanoplatelets
Authors: Antanovich Artsiom , Prudnikau Anatol , Artemyev Mikhail 
Published: April 2018

Abstract
Atomically flat colloidal nanoplatelets with strong one-dimensional confinement represent the most recently discovered type of quantum-confined cadmium chalcogenide nanocrystals. In almost a decade a great progress has been achieved in the colloidal synthesis of nanoplatelets and understanding of their basic optical and electronic properties. However, up until recently methods of their controlled spatial orientation were quite scarce, what in turn hindered obtaining reliable information on their anisotropic structural and optical properties arising from their shape. In this paper we provide a mini-review of recent advances in this field of study.
Fluorescence Quenching of CdTe Quantum Dots with Co (III) Complexes via Electrostatic Assembly Formation
Authors: Pal Anuushka , Arora Bhawna , Rani Diksha , Srivastava Sumit , Gupta Rajeev , Sapra Sameer 
Published: April 2018

Abstract
The photoluminescence quenching of CdTe QDs in the presence of three different Co (III)-complexes is studied to elucidate the role of interactions between functional groups of positively charged cysteamine capped CdTe QDs and negatively charged Co (III) complexes bearing carboxylic groups. The steady state and time resolved spectroscopy has been used to investigate the mechanism of quenching. After detailed analysis, it is concluded that quenching is contributed by both static as well as dynamic processes. The static contribution has been assigned to the electrostatic assembly formation via ionic interactions between the amine functional groups of positively charged cysteamine capped CdTe QDs and carboxylic acid groups of negatively charged complexes. The electrostatic interactions were confirmed by zeta potential measurement as well as from effect of salt addition. These studies have implications in designing donor/acceptor pairs having complementary functional groups for efficient optoelectronic devices or photocatalytic systems.
