Aims Few studies have evaluated the relationship between patients’ pre-operative expectations and the outcome of orthopaedic procedures. Our aim was to determine the effect of expectations on the outcome after primary anatomical total shoulder arthroplasty (TSA). We hypothesised that patients with greater expectations would have better outcomes. Patients and Methods Patients undergoing primary anatomical TSA completed the Hospital for Special Surgery’s Shoulder Expectations Survey pre-operatively. The American Shoulder and Elbow Surgeons (ASES), Shoulder Activity Scale (SAS), Short-Form-36 (SF-36), and visual analogue scale (VAS) for pain, fatigue, and general health scores were also collected pre-operatively and two years post-operatively. Pearson correlations were used to assess the relationship between the number of expectations and the outcomes. Differences in outcomes between those with higher and lower levels of expectations for each expectation were assessed by independent samples t-test. Multivariable linear regression analysis was used to control for potential confounding factors. Results A total of 67 patients were evaluated two years post-operatively. Most parameters of outcome improved significantly from baseline and most patients were satisfied. A greater number of expectations was associated with a significantly greater improvement in the ASES score (p = 0.02). In the multivariable analysis, a greater number of expectations was an independent predictor of better ASES, VAS and SF-36 scores, as well as improvements in ASES and VAS pain scores (p < 0.05). Greater expectations for many specific expectation questions were significantly associated with better outcomes (p < 0.05). Conclusion TSA is a successful procedure with significant improvements in outcome, and greater pre-operative expectations are associated with better outcomes.

Authors: Talbot C. , Adam J. , Paton R. 
Published: August 2017

Aims Despite the presence of screening programmes, infants continue to present with late developmental dysplasia of the hip (DDH), the impact of which is significant. The aim of this study was to assess infants with late presenting dislocation of the hip despite universal clinical neonatal and selective ultrasound screening. Patients and Methods Between 01 January 1997 to 31 December 2011, a prospective, longitudinal study was undertaken of a cohort of 64 670 live births. Late presenting dislocation was defined as presentation after three months of age. Diagnosis was confirmed by ultrasound and plain radiography. Patient demographics, referral type, reason for referral, risk factors (breech presentation/strong family history) and clinical and radiological findings were recorded. Results There were 31 infants with an irreducible dislocation of the hip, an incidence of 0.48 (95% confidence interval (CI) 0.34 to 0.68) per 1000 live births. Of these, 18 (0.28 (95% CI 0.17 to 0.44) per 1000 live births; 58%) presented late. All infants had a documented normal newborn clinical examination and no abnormality reported in the six to eight week check. Of the 18 late presenting cases 72% (n = 13) had no risk factors: 16 were referred by GPs and two were late due to administrative issues (missed appointments). The mean time to diagnosis was 62.4 weeks (19 to 84). Conclusion Despite universal clinical neonatal and selective ultrasound screening, late cases of irreducible hip dislocation still occur. We recommend an update of the national screening programme for DDH, a review of training and education of healthcare professionals involved in the physical examination of neonates and infants, and the addition of a further assessment after the six to eight week check.

Authors: Ali A. M. , Newman S. D. S. , Hooper P. A. , Davies C. M. , Cobb J. P. 
Published: August 2017

Objectives Unicompartmental knee arthroplasty (UKA) is a demanding procedure, with tibial component subsidence or pain from high tibial strain being potential causes of revision. The optimal position in terms of load transfer has not been documented for lateral UKA. Our aim was to determine the effect of tibial component position on proximal tibial strain. Methods A total of 16 composite tibias were implanted with an Oxford Domed Lateral Partial Knee implant using cutting guides to define tibial slope and resection depth. Four implant positions were assessed: standard (5° posterior slope); 10° posterior slope; 5° reverse tibial slope; and 4 mm increased tibial resection. Using an electrodynamic axial-torsional materials testing machine (Instron 5565), a compressive load of 1.5 kN was applied at 60 N/s on a meniscal bearing via a matching femoral component. Tibial strain beneath the implant was measured using a calibrated Digital Image Correlation system. Results A 5° increase in tibial component posterior slope resulted in a 53% increase in mean major principal strain in the posterior tibial zone adjacent to the implant (p = 0.003). The highest strains for all implant positions were recorded in the anterior cortex 2 cm to 3 cm distal to the implant. Posteriorly, strain tended to decrease with increasing distance from the implant. Lateral cortical strain showed no significant relationship with implant position. Conclusion Relatively small changes in implant position and orientation may significantly affect tibial cortical strain. Avoidance of excessive posterior tibial slope may be advisable during lateral UKA. Cite this article: A. M. Ali, S. D. S. Newman, P. A. Hooper, C. M. Davies, J. P. Cobb.

Reconsidering the Net Generation: Putting the focus back on the technological landscape
Authors: Lunceford Brett , Rockwell Steven C. 
Published: August 2017

Abstract
Scholars and pundits alike have devoted considerable attention to the so-called ‘Net Generation’, arguing that their status as ‘digital natives’ requires a complete reconception of how educators use technology. Although the explosion of educational technologies warrants closer examination, we argue that the need for this change comes not from some generational Zeitgeist, but rather the change in the technological landscape. Thus, a more fruitful approach is to examine educational technologies from a media ecology standpoint, considering what these technologies enhance, retrieve, reverse into and obsolesce.
‘I Remember You’: Exploring glam metal’s re-emergence in contemporary metal music markets
Authors: Kummer Jenna 
Published: August 2017

Abstract
Due to glam metal’s ‘We’re Not Gonna Take It’ attitude, the music was labeled by political groups such as the Parents’ Music Resource Center (PMRC) as being countercultural and therefore dangerous for youth to listen to during its peak in the 1980s. Since then, glam metal has been renewed amid a nostalgic performance circuit, but also in television as softer and more familiar in some respects. Through a critical discourse and semiotic analysis of glam metal in reality television and television advertising, this article considers which attributes of contemporary culture might complement provisional identification with an extinguished subcultural style. Considering the notions of recontextualization and the aesthetic of the apparently real alongside postmodern discussions of identity and authenticity, this article’s findings suggest a move towards commonly held values of mature neoliberalism in the return of the glam metal genre in today’s metal music markets.
The Revolution Will Be Working Class and Queer: Dos Passos’s Three Soldiers, Progressive Politics, and Revolutionary Rhetorics
Authors: Arnett James J. 
Published: August 2017

Abstract
Taking a look at the early, and in particular, the World War I novels of John Dos Passos, this article argues for the recognition and preservation of a revolutionarily ‘tender’ queer, working-class politics in those texts. Though scholars hardly agree that World War One was an explicitly queer or merely homosocial space, Dos Passos’s willingness to depict queer lives frankly and sympathetically earned criticism then, and critical silence now. This article probes Dos Passos’s early progressive politics as well as his significant rejection of them in the lead-up to World War Two, and argues that this reversal was not surprising, but may have led to the relative obscurity of these politics to even contemporary readers. Mobilizing recent radical queer politics described by Samuel Delany and theories of revolutionary love by Srecko Horvat, this essay argues that the inter-class contact, physical and social, creates the conditions whereby a challenge to capitalist alienation can be mounted by the men who emerge at these intersections.

Delays related to materials are one of main problems of construction project. An effective supply chain management has a significant role in preventing this type of delay. The aim of this research is develop risk simulation model of construction supply chain in buildings. The materials include steel bars, steel profiles, formwork, and precast concrete, as they are considered the main building material. The supply chain risks are classified from supply, control, process, and demand sides. Monte Carlo simulation has been performed using Cristal Ball software. Risk identification was done through literature review, site observation, and interviews with 29 contractor personnel working for nine building projects. The simulation results show that the minimum, maximum, and most frequent delays (in days), as follows: steel bars (2.20. 17.05, 11.24); steel profiles (2.12, 15.10, 9.75), formwork (1.79, 16.04, 10.45), precast concrete (1.76, 15.61, 10.24). The sensitivity analysis shows that delay due to change order from client is the most sensitive for steel bars, steel profiles, and formwork of 25.5%, 37.4%, dan 17%, respectively. The results of this research is useful for contractors and owners who can use them as a guidance in identifying, predicting, and mitigating supply chain risks for a successful project.

Published: August 2017

AbstractCurcumin is a natural product with enormous biological potential. In this study, curcumin synthesis was revisited using different reaction solvents, a catalyst (n-butylamine) and a water scavenger [(n-BuO)3B], to develop the optimal procedure for its rapid acquisition. During synthesis, solvent choice was found to be an important parameter for better curcumin yield and high purity. In a typical reaction, acetyl acetone was treated with boron trioxide, followed by condensation with vanillin in the presence of tri-n-butyl borate as water scavenger andn-butylamine as catalyst at 80 °C in ethyl acetate to afford curcumin. Moreover, curcumin was also extracted from turmeric powder and spectroscopic properties such as IR, MS,1H NMR and13C NMR with synthetic curcumin were established to identify any impurity. The purity of synthetic and extracted curcumin was also checked by TLC and HPLC-DAD. To computationally assess its therapeutic potential against cyclin dependent kinases (CDKs), curcumin was docked in different isoforms of CDKs. It was observed that it did not dock at the active sites of CDK2 and CDK6. However, it could enter into weak interactions with CDK4 protein.

Published: August 2017

Abstract
In this study, effects of the long-acting amide-type local anesthetic levobupivacaine on axonal conduction and excitability parameters of the rat sciatic nerve were thoroughly examined both in vitro and in vivo. In order to deduce its effects on isolated nerve conduction, compound nerve action potential (CNAP) recordings were performed using the suction method over sciatic nerves of Wistar rats before and after administration of 0.05 % (1.7 mmol L−1) levobupivacaine. Levobupivacaine caused complete CNAP area and amplitude depression by blocking conduction in a time-dependent manner.
To assess the influence of levobupivacaine on in vivo excitability properties, threshold-tracking (TT) protocols were performed at sciatic nerves of rats injected with perineural 0.05 % (1.7 mmol L−1) levobupivacaine or vehicle alone. Charge-duration TT results revealed that levobupivacaine increases the rheobase and decreases the strength-duration time constant, suggesting interference of the anesthetic with the opening of Na+ channels. Twenty and 40 % threshold electrotonus curves were found for both groups to follow the same paths, suggesting no significant effect of levobupivacaine on K+ channels for either the fastest or relatively slow conducting fibers. Current-threshold relationship results revealed no significant effect on axonal rectifying channels. However, according to the results of the recovery cycle protocol yielding the pattern of excitability changes following the impulse, potential deviation was found in the recovery characteristics of Na+ channels from the absolute refractory period. Consequently, conduction blockage caused by levobupivacaine may not be due to the passive (capacitive) properties of axon or the conductance of potassium channels but to the decrease in sodium channel conductance.

Authors: Molitorisová M. , Kotlářová J. , Snopková M. , Waczulíková I. 
Published: August 2017

Abstract
Introduction: Intervention of pharmacists in medication adherence can meaningfully contribute to achieving therapeutic outcomes. Exploring the real-life readiness and opportunities of pharmacists may result in the adoption of measures, which could be seen through improvement of patients’ adherence to pharmacotherapy.
Aim: The aim of the paper was to make a survey on community pharmacists’ potential in medication adherence support in its connectivity to technical and personnel factors, which underline the capacities of pharmacies in dealing with medication adherence.
Methods: The questionnaire survey was conducted from October to December 2014 and involved 158 pharmacists from 117 Czech (CZ) and 41 Slovak (SK) community pharmacies. The structured questionnaire surveyed both technical and personnel factors, including provision of consultancy services related to medication adherence. Non-adherence risk reduction was evaluated by adopting Morisky Scale modified from the pharmacist’s perspective. Questionnaires outcomes were summarised in contingency tables and analyzed for associations between respective categorical variables using χ2 or exact tests and association coefficients. All results are reported as significant at P≤0.05.
Results: The average score of adherence support (CZ/SK 1.95/1.93) was significantly higher as compared to that of persistence or concordance (P<0.001). Reduction of non-adherence risk reached the score of a medium degree (P=0.73, average 2.29 in CZ and 2.22 in SK). These findings were significantly associated with personnel capacities (provision of consultancy, preference for the use of recommended procedures in CZ (P<0.001), number of years of practice in SK (P=0.029)), while significant association with technical equipment (consultancy room) in the SK (P=0.037).
Conclusion: The pharmaceutical care is developing towards the improvement of medication adherence in both countries - assuming a medium degree of adherence support. Further progress may be observed in strengthening the pharmacists’ personnel capacities, and accelerated mainly using information technologies, i.e. through technical capacities.

Authors: Zhu Bo , Liu Jianli , Gao Weidong 
Published: August 2017

Abstract
This study was aimed at investigating the process optimization of foam sizing for cotton yarns. In this work, effects of major foam-sizing process factors including size concentration, blowing ratio, stirring speed, pre-wetting temperature, pre-drying temperature, squeezing pressure and drying temperature were studied on the hairiness (more than 3 mm) and abrasion resistance of foam-sized yarns. The combination of Plackett-Burman, steepest ascent path analysis and Box-Behnken design were adopted to optimize the foam-sizing process of cotton yarns. Results revealed that size concentration, blowing ratio and squeezing pressure were significant factors that affected the hairiness and abrasion resistance. Optimum hairiness and abrasion resistance were obtained when the cotton yarns were sized at size concentration of 19.33%, blowing ratio of 4.27 and squeezing pressure of 0.78kN. The theoretical values and the observed values were in reasonably good agreement and the deviation was less than 1%. Verifcation and repeated trial results showed that it has good reproducibility and imparts the foam sizing process of cotton yarns.
Müntz Spectral Methods for the Time-Fractional Diffusion Equation
Authors: Hou Dianming , Hasan Mohammad Tanzil , Xu Chuanju 
Published: August 2017

Abstract
In this paper, we propose and analyze a fractional spectral method for the time-fractional diffusion equation (TFDE).
The main novelty of the method is approximating the solution by using a new class of generalized fractional Jacobi
polynomials (GFJPs), also known as Müntz polynomials.
We construct two efficient schemes using GFJPs for TFDE: one is based on the Galerkin formulation
and the other on the Petrov–Galerkin formulation.
Our theoretical or numerical investigation shows that both schemes are exponentially convergent
for general right-hand side functions, even though the exact solution has very limited regularity (less than

H
1

{H^{1}}

).
More precisely, an error estimate for the Galerkin-based approach is derived to demonstrate its spectral accuracy, which is then confirmed by numerical experiments. The spectral accuracy of the Petrov–Galerkin-based approach is only
verified by numerical tests without theoretical justification.
Implementation details are provided for both schemes, together with
a series of numerical examples to show the efficiency of the proposed methods.

Abstract
In this paper, we introduce the q-analogue of the Jakimovski-Leviatan type modified operators introduced by Atakut with the help of the q-Appell polynomials.We obtain some approximation results via the well-known Korovkin’s theorem for these operators.We also study convergence properties by using the modulus of continuity and the rate of convergence of the operators for functions belonging to the Lipschitz class. Moreover,we study the rate of convergence in terms of modulus of continuity of these operators in aweighted space.
FSW between Al alloy and Mg Alloy: the comparative study
Authors: Jagadeesha C. B. 
Published: August 2017

AbstractIt is difficult to fusion weld Al alloy to Mg alloy, so by experimental optimization procedure (EOP) optimum parameters for FSW between Al alloy and Mg alloy were determined and experiment conducted using these parameters resulted in not only sound weld but also highest strength weld for 5 mm thickness of the alloys plates. One can arrive to optimum parameters by following the EOP in case of similar and dissimilar materials FSW, such as Al alloy and Mg alloy FSW. It has observed that tensile sample having least thickness intermetallics (IMs) layer has highest strength compared to sample with larger thickness of intermetallics layer and also it has observed that weld of lesser thickness plates have strength higher than welds of larger thickness plates. It has observed that, Vickers hardness in WN i.e. on the region containing layers of IMs is considerably higher, which leads to emerge of new type of laminated composite materials. It has observed that, it is the least thickness IMs layers in the weld are responsible for higher strength of weld not the ductility of the IMs formed owing to the insertion of intermediate material in the weld. It has found that coefficient of friction is =0.25, in case of bead on plate welding of Mg alloy.
Electrical transport and magnetoresistance of double layered CMR manganites R1.2Sr1.8Mn2O7(R = La, Pr, Sm)
Authors: Reddy Y.S. 
Published: August 2017

AbstractPolycrystalline bulk samples of double layered (DL) colossal magnetoresistive (CMR) manganites R1.2Sr1.8Mn2O7(R = La, Pr, Sm) were prepared by sol-gel method to study the effect of size of lanthanide ion on their magnetotransport properties. The electrical resistivity of the samples was investigated in the temperature range of 70 K to 300 K at different magnetic fields. The samples LSMO and PSMO show insulator-to-metal transition (IMT) behavior, while SSMO sample exhibits insulating behavior in the entire temperature range with a very large value of resistivity. The insulator-to-metal transition temperature (TIM) decreases from 123 K (LSMO) to 90 K (PSMO) and disappears in SSMO sample. To explain the electrical transport above TIM, the temperature dependent resistivity data (T > TIM) of all the samples were fitted to the equations of different conduction models. The results indicate that the conduction at T > TIMis due to Mott variable range hopping (VRH) mechanism in the LSMO and PSMO samples, while Efros-Shkloskii (ES) type of VRH model dominates the conduction process in the SSMO sample. All the three samples show increasing magnetoresistance (MR) even below TIMand the maximum MR is shown by LSMO (39 % at 75 K, 3 T).
Optical and structural properties of nanostructured copper oxide thin films as solar selective coating prepared by spray pyrolysis method
Authors: Asadi M. , Rozati S.M. 
Published: August 2017

AbstractCopper (II) oxide thin films were prepared by spray pyrolysis method on soda-lime glass substrates using copper acetate precursor solution. Influence of substrate temperature on structural and optical properties was investigated. Structural analysis of these layers were carried out by X-ray diffraction (XRD). Single phase nature and high crystallinity of CuO nanostructures were observed on XRD patterns. The general appearance of the films was uniform and black in color. FT-IR transmittance spectra confirmed the results from the XRD study. Selective solar absorber coatings of copper oxide (CuO) on stainless steel substrates was prepared by spray pyrolysis method. Effect of deposition temperature on optical properties of thin films was investigated. Optical parameters, absorbance (α) and emittance (α) were evaluated from reflectance data. It can be deduced that the porous structure, such as a light traps, can greatly enhance absorbance, while the composition, thickness and roughness of thin films can greatly influence the emissivity. Single phase nature and high crystallinity of CuO nanostructures were observed by XRD patterns. Solar absorbance of thin films were in the range of 85 % to 92 %.
