Authors: Nagra N. S. , Zargar N. , Smith R. D. J. , Carr A. J. 
Published: February 2017

Objectives All-suture anchors are increasingly used in rotator cuff repair procedures. Potential benefits include decreased bone damage. However, there is limited published evidence for the relative strength of fixation for all-suture anchors compared with traditional anchors. Materials and Methods A total of four commercially available all-suture anchors, the ‘Y-Knot’ (ConMed), Q-FIX (Smith & Nephew), ICONIX (Stryker) and JuggerKnot (Zimmer Biomet) and a traditional anchor control TWINFIX Ultra PK Suture Anchor (Smith & Nephew) were tested in cadaveric human humeral head rotator cuff repair models (n = 24). This construct underwent cyclic loading applied by a mechanical testing rig (Zwick/Roell). Ultimate load to failure, gap formation at 50, 100, 150 and 200 cycles, and failure mechanism were recorded. Significance was set at p < 0.05. Results Overall, mean maximum tensile strength values were significantly higher for the traditional anchor (181.0 N, standard error (se) 17.6) compared with the all-suture anchors (mean 133.1 N se 16.7) (p = 0.04). The JuggerKnot anchor had greatest displacement at 50, 100 and 150 cycles, and at failure, reaching statistical significance over the control at 100 and 150 cycles (22.6 mm se 2.5 versus 12.5 mm se 0.3; and 29.6 mm se 4.8 versus 17.0 mm se 0.7). Every all-suture anchor tested showed substantial (> 5 mm) displacement between 50 and 100 cycles (6.2 to 14.3). All-suture anchors predominantly failed due to anchor pull-out (95% versus 25% of traditional anchors), whereas a higher proportion of traditional anchors failed secondary to suture breakage. Conclusion We demonstrate decreased failure load, increased total displacement, and variable failure mechanisms in all-suture anchors, compared with traditional anchors designed for rotator cuff repair. These findings will aid the surgeon’s choice of implant, in the context of the clinical scenario. Cite this article: N. S. Nagra, N. Zargar, R. D. J. Smith, A. J. Carr.

Beneath the bias, the crisis: The press, the independent media and the Scottish referendum
Authors: Wayne Michael 
Published: February 2017

Abstract
This article examines the coverage of the Scottish referendum of 2014 by the press in the context of a multi-nation state with diverging political cultures. Evidence of press bias is assessed but the article argues that the more interesting question is why, despite the bias, there was considerable neutrality or even pro-independence views, given that the referendum posed an existential threat to the British state? The article argues that the political crisis was also a crisis for some sections of the press, who in a complex and contradictory context had their un-reflexive unionism mitigated. Signs of historic re-alignments among the Scottish electorate – especially the working class vote – threw the press on the defensive. The article also considers the impact of the independent media and the use of the Internet and social media to facilitate a grassroots campaign for independence, which again made the press look out of touch with popular currents. The political and media crisis is situated in the context of the contest between neo-liberalism and social democracy and draws on a Gramscian framework to analyse this.

Authors: Stopková L. , Hriňaková A. , Bezáková Ž. , Andriamanty F. , Žufková V. 
Published: February 2017

Abstract
In this manuscript was investigated behaviour of drug valsartan by micellar media of anionic surfactant sodium dodecyl sulphate. As the method was used electrical conductivity for the determination of critical micelle concentration at different temperatures (T = 293.15 - 313.15 K), as well as calculated thermodynamic parameters like standard Gibbs free energy, enthalpy and entropy of micellization. According to contribution of Gibbs free energy is the process of micellization primarily controlled by entropy. Solubilization of valsartan was studied in surfactant system at 298.15 K and physiological conditions pH 7.4 using UV-spectrophotometry at different concentration range (0.001 - 0.07 mol/l) of sodium dodecyl sulphate. The solubilization of drug was observed with increasing concentration of surfactant in aqueous solution.

Published: February 2017

Abstract
Combinatorial library of novel benzenesulfonamides was docked (Schrodinger Glide) into mycobacterial carbonic anhydrase (mtCA II) and human (hCA II) isoforms with an aim to find drug candidates with selective activity on mtCA II. The predicted selectivity was calculated based on optimized MM-GBSA free energies for ligand enzyme interactions. Selectivity, LogP (o/w) and interaction energy were used to calculate the selection index which determined the subset of best scoring molecules selected for further evaluation. Structure-activity relationship was found for fragment subsets, showing us the possible way regarding how to influence lipophilicity without affecting ligand-enzyme binding properties.
Dal Cairo a Roma. Visual Arts and Transcultural Interactions between Egypt and Italy
Authors: Radwan Nadia 
Published: February 2017

Abstract
Cross-cultural interactions between Egypt and Italy have had a significant impact on Egyptian modern art. By the end of the nineteenth century many Italian painters had established their studios in Cairo and Alexandria and worked as professors in art schools. They were committed to the institutionalization of the artistic practice, in particular, in the conception of the School of Fine Arts in Cairo established by Prince Youssef Kamal in 1908. Additionally, a number of young Egyptians belonging to the generation of the so-called “pioneers” received grants to study art in Italy, in particular in Rome and Florence. These ties were strengthened by the political climate and the diplomatic relationships between the Egyptian monarchy and the Italian government. This article proposes to examine the impact on visual culture created by the mobility of artists and circulation of images between Egypt and Italy. In this context, it aims to shed light on transnational exchanges and networks generated by spaces of cultural encounters or “contact zones” during the first quarter of the twentieth century.
Am I Obliged to Imitate You? On Copying the Grande Odalisque for the Ottoman Collection of Paintings Elvah-ı Nakşiye
Authors: Artun Deniz 
Published: February 2017

Abstract
In 1813, Caroline Murat, the Queen of Naples and Napoleon’s youngest sister, commissioned Jean-Auguste Ingres, the director of Villa Medici at the time, a painting (Ingres 1994: 66). It was upon this commission that Ingres created in Rome, the future icon of orientalism: La Grande Odalisque. The most reproduced masterpiece of the Louvre, second only to the Mona Lisa, La Grande Odalisque was copied by a “young Turk”, Haşmet Aral in 1951. Aral was sent to Paris with a state scholarship aimed at expanding his expertise in painting and this time it was his commission to paint the Odalisque. Upon his return, his copy was represented in the museum of copies, an initiative launched in 1915 by historian and museologist Halil Edhem, brother of celebrated Osman Hamdi, and expanded by several of his followers. This paper will bring to the foreground Haşmet Aral’s encounter as a copyist of Odalisque, with the views of Lhote and Leger, the masters he worked with in Paris, on the task of copy and Ingres. It will also dwell on the “achievements” of Aral as compared to other copyists and interpreters of the Ingres’ masterpiece among whom are Delacroix, Picasso, Matisse and Modigliani. And finally it will bring on the agenda the context and possible effects of the inclusion of La Grande Odalisque to the collection of a museum in Istanbul, the old capital of the Orient, at a time when orientalism was not yet criticised.
Aesthetics of Decolonization – The Magazine Souffles (1966–1972)
Authors: von Osten Marion 
Published: February 2017

Abstract
The magazine Souffles was published by intellectuals and poets in Morocco from 1966 to 1972. It functioned as a node, medium, and interface in the intellectual, political and artistic production of a post-colonial subjectivity. Going beyond existing studies of Souffles that mainly looked on its relevance for literature production in Morocco, this article highlights the contributions by visual artists and transnational solidarity movements for the magazine’s translocal constitution. This includes encounters, relations and transfers between radical art and political discourses and practices, as well as the transnational context in which the magazine’s post-colonial aesthetic proposals emerged. The article is based on insights conducted in a research project with the same title that studies the magazine’s polyphone character in a trans-disciplinary manner. It combines artistic research, interviews and conversations looking closely at the visual and aesthetic proposals as well as written testimonies in dialogue with a socio-political reading of the publication, considering as well recent theories on aesthetics and concepts developed in the field of postcolonial studies.
Semi-formal verification of closed-loop specifications in the concept design phase
Authors: Richter Jan H. , Friedrich Stefan R. 
Published: February 2017

Abstract
The article addresses the semi-formal verification of behavioral specifications for subsystems consisting of physical
parts and controllers, complemented by simulation-based integration testing. Since design errors in early phases tend to
be particularly expensive, the method is tailored towards applicability in these phases. We verify behavioral
specifications with proof-like credibility, or falsify them while providing a violation scenario that is reusable as
a test case. The system is represented as a mixed logical dynamical (MLD) system, and specifications are expressed by
a temporal logic with affine signal abstractions. The verification problem is converted into an equivalent mixed-integer
linear feasibility problem solved using off-the-shelf solvers. An example illustrates the effectiveness of the method.
sss & sssMOR: Analysis and reduction of large-scale dynamic systems in MATLAB
Authors: Castagnotto Alessandro , Varona Maria Cruz , Jeschek Lisa , Lohmann Boris 
Published: February 2017

Abstract
We present two MATLAB toolboxes, provided as open-source code, that expand the capabilities of the Control System Toolbox
to large-scale models. sss allows the definition and analysis of sparse state-space (sss)
objects with functions (such as bode, step, norm,…) revisited to exploit the
sparsity of the system matrices. sssMOR entails model reduction algorithms that capture the relevant
dynamics of high order systems in models of significantly lower dimensions. The sssMOR_App provides a graphical
user interface for easy interaction with the tools. With sss and sssMOR it is possible to
analyze dynamical systems with state-space dimensions higher than O(104), which is typically the limit for
built-in ss objects. In this contribution, we give a first introduction to the toolboxes and the main
functionality. Numerical examples show the advantages of using the tools.
Mother Sense, Language, and Logic
Authors: Petrilli Susan 
Published: February 2017

AbstractVictoria Welby conceived a special approach to the theory of meaning, which she designated with the expressionSignifics. A central concept in her works is what she namesmother sense, which she discusses in her correspondence with such figures as the English philosopher Ferdinand C. S. Schiller and the American pragmatist Charles Sanders Peirce, among others. Beyond her contribution to questions of the linguistic, semiotic, practical ethical, and pedagogical orders, the implications of her theory of meaning are particularly interesting for the “woman question” and for feminist discourse generally.

Published: February 2017

Abstract
The preparation of oligochitosan through the heterogeneous degradation of chitosan/H2O2 combined with the homogeneous reaction of chitosan with H2O2 under gamma radiation was studied. Oligochitosan with weight-average molecular weight (Mw) of less than 10 kDa could be efficiently prepared by gamma Co60 irradiation of chitosan solution (4%) and hydrogen peroxide (0.5%) at doses ranging from 8 to 24 kGy. The Mw, chemical structure, and the crystallinity of chitosan and oligochitosan were characterized by GPC, FT-IR, and XRD. The solubility and antioxidant activity of chitosan and of oligochitosan with the different molecular weights were investigated. Results showed that oligochitosan CS5 (20 kGy) and CS6 (24 kGy) have good solubility in the pH range of 3 to –11. The scavenge percentage of CS5 against 2,2-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical is 99.2% in 90 min. The antioxidant activity of oligochitosan is effective in a short time period; therefore, it has potential application as an effective and natural antioxidant.
Soret and Dufour Effects on Three Dimensional Upper-Convected Maxwell Fluid with Chemical Reaction and Non-Linear Radiative Heat Flux
Authors: Ramzan M. , Bilal M. , Chung Jae Dong 
Published: February 2017

Abstract
Three dimensional chemically reactive upper-convected Maxwell (UCM) fluid flow over a stretching surface is considered to examine Soret and Dufour effects on heat and mass transfer. During the formulation of energy equation, non-linear radiative heat flux is considered. Similarity transformation reduces the partial differential equations of flow problem into ordinary differential equations. These non-linear differential equations are then solved by using bvp4c MATLAB built-in function. A comparison of the present results with the published work is also included. Effects of some prominent parameters such as Soret and Dufour number, chemical reaction parameter, Prandtl number, Schmidt number and thermal radiation on velocity, temperature and concentration are discussed graphically and numerically. A comparison with the previously published work is also included in a tabular form.
The effects of antenatal glucocorticoid exposure on fetal and neonatal skin maturation
Authors: August Deanne , Kandasamy Yogavijayan 
Published: February 2017

AbstractAims:The use of antenatal glucocorticoids in women with preterm labor has dramatically improved outcomes for premature infants. The most commonly used antenatal glucocorticoids are betamethasone and dexamethasone. Glucocorticoids accelerate fetal lung growth by several mechanisms, including the maturation of type II pneumocytes enabling surfactant production. Furthermore, the lipids in the lung share similarity with those in the skin. Therefore, antenatal administration of glucocorticoids may have effects on the structure and function of the developing epidermal barrier in fetuses and neonates.Methods:We performed a systematic review to characterize these effects, identifying 11 studies (six animal and five human studies).Results:Five out of the six animal studies used a rodent model for investigating the effects of antenatally administered glucocorticoids, while the other used an ovine model. Antenatally administered glucocorticoids accelerated skin maturation in animal studies, but studies of human fetuses found conflicting results. None of the reviewed studies compared the effects of different types of glucocorticoids.Conclusions:More human studies are needed to fully understand the effects of antenatal steroids. However, as the antenatal use of glucocorticoids in preterm pregnancies has become part of standard clinical practice, it would be unethical to carry out a large randomized controlled trial. We may have to rely on animal models to improve our understanding of the effects of antenatal glucocorticoid exposure on the fetal and neonatal skin maturation.

AbstractFe and Si films were tested as corrosion protection layers for Zr in nuclear industry applications. Surface chemistry of Zr in dependence on the preparation conditions and layout of the films was complexly investigated by various spectroscopic and microscopic techniques. Corrosion experiments were carried out in autoclave conditions with in-situ Electrochemical Impedance Spectroscopy. A clean Zr surface is characteristic with disposition to disorder and rough morphology demonstrated in facets, steps or terraces. Upon deposition of Fe and Si atoms in amounts in the order of single monolayers and subsequent annealing at 400°C, the original (1×1) Zr surface structure rearranges into (2√3×2√3)R30°. Corrosion experiments show that a thicker Si overlayer successfully suppresses oxygen uptake of the underlying Zr material by forming a diffusion barrier. The barrier effect of the films was also confirmed for hydrogen.

Published: February 2017

Abstract
In the present work, β-cyclodextrin was grafted to the surface of ZSM-5 via 2,3-epoxypropyl trimethylammonium chloride (ETMAC) and epichlorohydrin (EPI) as the bridging agent by ion exchange and sequential grafting. The mixed matrix membranes were prepared using polyurethane (PU) and ZSM-5 before and after modification. Modified ZSM-5 and corresponding MMM were characterized by Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and scanning electron microscope (SEM). These membranes were applied for the removal of phenol from aqueous solution in pervaporation process. The results showed that modified ZSM-5 dispersed homogeneously in polymer. The flux and pervaporation separation index of PU increased greatly with a limited decrease in selectivity by the addition of modified ZSM-5. The increased feed temperature enhanced both the flux and separation factor of PU and modified PU membranes.

Published: February 2017

Abstract

Introduction
The main target of this study was to compare the effects of nitrogen limitation and light intensities on cell growth, lipid content and fatty acid profile of Nitzschia sp.

Methods
F/2 medium and N-free F/2 medium were both tested at two different light intensities of 11 and 56 μEm−2s−1 in the internal loop air-lift photobioreactor for Nitzschiasp.

Results
The presence of nitrogen led to more cells grown efficiently. Furthermore, the increase in chlorophyll content went parallel to the increase in dry weight. The most abundant saturated and monounsaturated fatty acids were pentadecanoic acid (C15:0) and palmitoleic acid (C16:1) which constituted 17%–42% and 15%–48% of total fatty acids for all growth conditions, respectively. It was recorded that palmitoleic acid was present at higher concentrations than palmitic acid.

Discussion and conclusion
The noteworthy finding was that the lipid content increased with increasing the growth rate of Nitzschia sp. under phototrophic conditions.
Role of halogen substituents in a series of polymorphic 2,5-diamino-3,6-dicyanopyrazine derivatives with highly flexible groups

Published: February 2017

Abstract
The crystal structures of the ortho-X-benzyl derivatives, where X=F, Cl, Br, I, and Me, of 2,5-bis(N,N-dibenzylamino)-3,6-dicyanopyrazine dyes (C34H24N6X4) were analysed to evaluate the effect of a systematic series of structures on the occurrence of polymorphism. Detailed crystal structure analysis indicated that the thermally stable forms of the polymorphic derivatives (Cl and Br derivatives) were close-packed, whereas those of the non-polymorphic derivatives (F and I derivatives) were stabilised by an intermolecular interaction involving the ortho-substituents. In the thermally metastable forms of the polymorphic derivative, halogen-halogen and halogen-nitrogen interactions contributed to the stabilisation of these crystals in the same way as the thermally stable form of the non-polymorphic derivatives. This indicated that the ease of polymorph occurrence would require an appropriate balance between the crystal energy of the close-packed structure and that of the crystal structure generated mainly by the electrostatic interactions involving the halogens in these halogenated pyrazine derivatives. In addition, the similar tendency of the occurrence of polymorphs in these halogenated pyrazine derivatives was found in 19 sets of halogenated compounds having known crystal structures of F, Cl, Br and I derivatives including at least one polymorphic derivative in the crystal structure database.
