Circular Economy Rebound
Authors: Zink Trevor , Geyer Roland 
Published: February 2017

SummaryThe so‐called circular economy—the concept of closing material loops to preserve products, parts, and materials in the industrial system and extract their maximum utility—has recently started gaining momentum. The idea of substituting lower‐impact secondary production for environmentally intensive primary production gives the circular economy a strong intuitive environmental appeal. However, proponents of the circular economy have tended to look at the world purely as an engineering system and have overlooked the economic part of the circular economy. Recent research has started to question the core of the circular economy—namely, whether closing material and product loops does, in fact, prevent primary production. In this article, we argue that circular economy activities can increase overall production, which can partially or fully offset their benefits. Because there is a strong parallel in this respect to energy efficiency rebound, we have termed this effect “circular economy rebound.” Circular economy rebound occurs when circular economy activities, which have lower per‐unit‐production impacts, also cause increased levels of production, reducing their benefit. We describe the mechanisms that cause circular economy rebound, which include the limited ability of secondary products to substitute for primary products, and price effects. We then offer some potential strategies for avoiding circular economy rebound. However, these strategies are unlikely to be attractive to for‐profit firms, so we caution that simply encouraging private firms to find profitable opportunities in the circular economy is likely to cause rebound and lower or eliminate the potential environmental benefits.
OSA and cardiometabolic risk: What's the bottom line?
Authors: Hoyos Camilla M. , Drager Luciano F. , Patel Sanjay R. 
Published: February 2017

ABSTRACT
Obstructive sleep apnoea (OSA) is a common condition characterized by repetitive upper airway obstruction during sleep. OSA promotes wide intrathoracic pressure swings, intermittent hypoxia and sleep fragmentation. Growing evidence derived from animal models mimicking the oxygen profile observed in patients with OSA as well as clinical studies support that this important sleep‐disordered breathing is associated with increased cardiovascular risk. Although the precise mechanisms are not fully established, it is conceivable that the metabolic deregulation promoted by the components of OSA may have an important causal role in the poor cardiovascular prognosis. In this review, we summarize the potential role of OSA and its components on cardiometabolic disease. We also summarize evidence evaluating the impact of OSA treatment (notably continuous positive airway pressure) on reversing the metabolic deregulation promoted by OSA. Finally, we discuss the research agenda and perspectives for this important research area.

Published: February 2017

SummaryPhotosystem I (PSI) is the most efficient bioenergetic nanomachine in nature and one of the largest membrane protein complexes known. It is composed of 18 protein subunits that bind more than 200 co‐factors and prosthetic groups. While the structure and function of PSI have been studied in great detail, very little is known about the PSI assembly process. In this work, we have characterized a PSI assembly intermediate in tobacco plants, which we named PSI*. We found PSI* to contain only a specific subset of the core subunits of PSI. PSI* is particularly abundant in young leaves where active thylakoid biogenesis takes place. Moreover, PSI* was found to overaccumulate in PsaF‐deficient mutant plants, and we show that re‐initiation of PsaF synthesis promotes the maturation of PSI* into PSI. The attachment of antenna proteins to PSI also requires the transition from PSI* to mature PSI. Our data could provide a biochemical entry point into the challenging investigation of PSI biogenesis and allow us to improve the model for the assembly pathway of PSI in thylakoid membranes of vascular plants.
Synergy of Electrostatic and van der Waals Interactions in the Adhesion of Epoxy Resin with Carbon-Fiber and Glass Surfaces
Authors: Yoshizawa Kazunari , Semoto Takayuki , Hitaoka Seiji , Higuchi Chisa , Shiota Yoshihito , Tanaka Hiromasa 
Published: February 2017

Abstract
The adhesion between epoxy resin and carbon fiber is investigated by using pair interaction energy decomposition analysis (PIEDA), by which the adhesive interaction energy and adhesive force can be partitioned into the electrostatic, exchange-repulsion, charge-transfer, and van der Waals (dispersion) contributions. The three stabilizing electrostatic, charge-transfer, and dispersion effects are correlated with the destabilizing exchange-repulsion effect. The surface structures of carbon fiber are modeled by the basal face, the armchair-edge structure, and the OH-functionalized armchair-edge structure of graphite. The surface of α-cristobalite (covered with OH groups), which can be viewed as a good model of a hydrophilic glass surface, is also studied. Adhesive properties of the model interfaces are evaluated on the basis of the binding energy of the resin with the carbon and glass surfaces and the adhesive force acting at the interfaces in terms of energy decomposition. PIEDA calculations demonstrate that only dispersion interactions can substantially work in the hydrophobic surfaces of the basal face and armchair-edge structures. This is a direct consequence of the electrostatic and charge-transfer interactions being cancelled by the exchange-repulsion interactions. On the other hand, both electrostatic and dispersion interactions are significant in the OH-functionalized surfaces of the armchair edge of graphite and α-cristobalite.

Published: February 2017

Abstract
Oligo(naphthalene-2,3-diyl)s were synthesized by iterative cross-coupling of 1,8-diaminonaphthalene-modified 3-iodo-2-naphthylboronic acids prepared from naphthalenes via Ir-catalyzed C–H borylation, Ru-catalyzed ortho-C–H silylation directed by an anthranilamide-modified boronyl group, and subsequent iododesilylation. The introduction of a chiral diol to the retained terminal boronyl group allowed selective induction of P- or M-helical conformations.
Fractured silences and youth dystopia in Maïssa Bey’s theatrical writings
Authors: Mehta Brinda J. 
Published: February 2017

Abstract
This study examines youth dystopia and fractured silences in the theatrical writings of Maïssa Bey. These silences are a narrative strategy to represent the ambivalent experiences that dominate and circumscribe the lives of Algerian youth – clandestine migration, child suicide, and intellectual confinement in the prison system. These fractures are located in the liminal spaces between speech and silence, life and death, hope and despair, resistance and surrender to provide alter-narratives articulated from the margins of society. The characters’ painful silences are nonetheless reconfigured into a fragmented and introverted language of thwarted words as a means to give voice to silence and social dispossession. Bey’s writings represent a form of testimonial writing and a denunciation of Algeria’s postcolonial malaise.
The complicated identity negotiation of women in Kangni Alemdjrodo’s Chemin de Croix and Gustave Akakpo’s Catharsis
Authors: Koriko Hamzat , Weaver-Hightower Rebecca 
Published: February 2017

Abstract
Third World feminists have long worked to bring to postcolonial studies a more nuanced reading of women’s lives in formerly colonized spaces. Postcolonial drama provides a fitting venue for such Third World feminists desiring to represent the realities of postcolonial African women. This article brings into conversation the post-colonial dramatists, the francophone playwrights, Kangni Alemdjrodo and Gustave Akapko, who have heretofore been unmentioned for their work as a catalyst for social change or as commentators on Third World feminism. Alemdjrodo and Akapko, both Togolese playwrights, are significant for their efforts to create space for debates over the complicated social expectations and identity negotiations of contemporary African women. In particular, Almedjrodo’s play Chemin de Croix (2005) and Akakpo’s play Catharsis (2006) deserve further analysis for their exploration through drama of the dilemmas many African women face when choosing between ‘traditional’ views of African femininity and western feminism as part of a personal struggle for autonomy and empowerment.

Published: February 2017

AbstractIn this paper, a two element frequency reconfigurable multiple-input-multiple-output (MIMO) antenna system is presented. The proposed antenna consists of miniaturized patch antenna elements, loaded with varactor diodes to achieve frequency reconfigurability. The antenna has bandwidth of 30 MHz and provides a smooth frequency sweep from 2.12 GHz to 2.4 GHz by varying the reverse bias voltage of varactor diode. The antenna is designed on an FR4 substrate and occupies a space of 50×100 × 0.8 mm
Testing Equality of Treatments under an Incomplete Block Crossover Design with Ordinal Responses
Authors: Lui Kung-Jong 
Published: February 2017

AbstractThe generalized odds ratio (GOR) for paired sample is considered to measure the relative treatment effect on patient responses in ordinal data. Under a three-treatment two-period incomplete block crossover design, both asymptotic and exact procedures are developed for testing equality between treatments with ordinal responses. Monte Carlo simulation is employed to evaluate and compare the finite-sample performance of these test procedures. A discussion on advantages and disadvantages of the proposed test procedures based on the GOR versus those based on Wald’s tests under the normal random effects proportional odds model is provided. The data taken as a part of a crossover trial studying the effects of low and high doses of an analgesic versus a placebo for the relief of pain in primary dysmenorrhea over the first two periods are applied to illustrate the use of these test procedures.
Nano-12-Tungstophosporic Acid Cesium Salt Synthesized by Ultrasound as Catalyst for Alkylation of Benzene with dec-1-ene
Authors: Akbay Elif , Demir Gülberk 
Published: February 2017

Abstract
Nano 12-tungtophosphoric acid cesium salt (Cs-TPA) was synthesized under ultrasonic irradiation in nanoscale. The obtained catalyst was characterized by various methods. These analyzes indicate that the chemical structure and crystallinity of nano Cs-TPA remained unchanged while its morphology was found to be different from traditional Cs-TPA which is in irregular shape, becoming spherical with an average particle size of about 50 nm.
Nano Cs-TPA was examined in the alkylation of benzene with dec-1-ene, its catalytic activity was remarkably enhanced compared to its original state. The catalyst reusability experiment also showed that the activity of nano Cs-TPA does not decrease even after five reused cycles.
Analysis about Heat Transfer of Vegetables during Cold Shock Treatment and Preservation Quality after Storage
Authors: Zhao Yang , Mingfeng Chen , Aiqiang Chen , Na Zhang , Songsong Zhao 
Published: February 2017

Abstract
This study investigated the heat transfer mechanism and preservation quality of axisymmetric vegetables during cold shock treatment (CST). A simulation model of heat transfer was developed based on geometrical and biological characteristics of the vegetables by finite element difference method. CST for cucumbers and carrots with cold water at 0°C (40 min), 2°C (20, 40 and 60 min) and 4°C (40 min) was conducted to evaluate the relationships between heat transfer characteristics and preservation quality. The comparative analysis shown that the simulated results agreed well with measured results. Meanwhile, in terms of weight loss, firmness and POD activity, CST with cold water at 2°C for 40 min could achieve the most positive effect on preserving cucumbers. The cucumber during treatment experienced whole variable temperature stage and appropriate constant temperature stage so as to reach optimal preservation quality.
Nurse-Environment Interactions in the Development of Cultural Competence
Authors: Blanchet Garneau Amélie , Pepin Jacinthe , Gendron Sylvie 
Published: February 2017

AbstractStudies on the development of cultural competence among healthcare providers tend to focus on the clinical encounter, with little attention paid to the environment. In this paper, results from a grounded theory study conducted with nurses and students to understand cultural competence development are presented; with a focus on findings that call particular attention to nurse-environment interactions. Two concurrent processes, as students and nurses develop cultural competence through interactions with their environment, were identified: “dealing with structural constraints” and “mobilizing social resources”. These dynamic interactions between healthcare providers and the larger structures of healthcare systems raise critical questions about the power of healthcare providers to influence the structures that shape their practice. The intersection of nursing theory with social and critical theories is essential to gain a comprehensive understanding of cultural competence development and to transform healthcare providers’ education in the service of social justice and health equity.
On narrowing the gap between verification and systematic testing
Authors: Christakis Maria 
Published: February 2017

Abstract
Our work on narrowing the gap between verification and systematic
testing has two directions: (1) complementing verification with
systematic testing, and (2) pushing systematic testing toward
reaching verification.
In the first direction, we explore how to effectively combine static
analysis with systematic testing, so as to guide test generation
toward properties that have not been previously checked by a static
analyzer in a sound way. This combination significantly reduces the
test effort while checking more unverified properties.
In the second direction, we push systematic testing toward checking as
many executions as possible of a real and complex image parser, so as
to prove the absence of a certain class of errors. This verification
attempt required no static analysis or source code annotations; our
purely dynamic techniques targeted the verification of the parser
implementation, including complicated assembly patterns that most
static analyses cannot handle.
Neural Network Classifier for Fighter Aircraft Model Recognition
Authors: Roopa K. , Rama Murthy T. V. , Prasanna Raj P. Cyril 
Published: February 2017

Abstract
Fighter aircraft recognition is important in military applications to make strategic decisions. The complexity lies in correctly identifying the unknown aircraft irrespective of its orientations. The work reported here is a research initiative in this regard. The database used here was obtained by using rapid prototyped physical models of four classes of fighter aircraft: P51 Mustang, G1-Fokker, MiG25-F, and Mirage 2000. The image database was divided into the training set and test set. Two feature sets, Feature Set1 (FS1) and FS2, were extracted for the images. FS1 consisted of 15 general features and FS2 consisted of 14 invariant moment features. Four multilayered feedforward backpropagation neural networks were designed and trained optimally with the normalized feature sets. The neural networks were configured to classify the test aircraft image. An overall accuracy of recognition of 91% and a response time of 3 s were achieved for the developed automatic fighter aircraft model image recognition system.
A studying on load transfer in carbon nanotube/epoxy composites under tension
Authors: Viet N. V. , Wang Q. , Kuo W. S. 
Published: February 2017

Abstract
The shear-lag model is developed to study the effect of geometry and material properties of epoxy and carbon nanotubes on load transfer in carbon nanotube/epoxy composites under tension. The results from proposed shear-lag model are validated by finite element method and the Haque’s model. Results show that the aspect ratio of the half-length to the outer radius of carbon nanotubes and their layer number have significant influence on load transfer in the composites. On the other hand, this research reveals new findings, which are not reported in other previous works. That is, no noticeable influences of the epoxy Young’s modulus and the interface shear modulus between epoxy matrix and carbon nanotube layers are found on load transfer in terms of the saturated stress length. In addition, the carbon nanotube volume percentage is found not affecting the load transfer. This research presents a better understanding on mechanical properties of carbon nanotube/epoxy composites.
Geometrically nonlinear large deformation of CNT-reinforced composite plates with internal column supports
Authors: Zhang L. W. 
Published: February 2017

Abstract
The geometrical nonlinear analysis of internally supported nanocomposite plates subjected to a uniformly distributed load is carried out. This study investigates the effects of internal point/column supports on the large deformation bending of nanocomposite plates reinforced by carbon nanotubes (CNTs) with different types of distributions, namely, uniform and two kinds of functionally graded distributions through the thickness of the plates. Two-dimensional displacement field of the plate is approximated by a set of Improved Moving Least Squares (IMLS) functions. The arc-length iterative algorithm with the modified Newton method is employed to obtain the nonlinear response of nanocomposite plates. Convergence studies indicate the validity and effectiveness of the element-free IMLS-Ritz method. The effects of plate thickness-to-width ratio, volume fraction ratio, and plate aspect ratio on the large deformation behavior of nanocomposite plates under various boundary conditions are examined. To the best of the authors’ knowledge, the problem has not been attempted in the open literature.
Error estimates for higher-order finite volume schemes for convection–diffusion problems
Authors: Kröner Dietmar , Rokyta Mirko 
Published: February 2017

AbstractIt is still an open problem to provea priorierror estimates for finite volume schemes of higher order MUSCL type, including limiters, on unstructured meshes, which show some improvement compared to first order schemes. In this paper we use these higher order schemes for the discretization of convection dominated elliptic problems in a convex bounded domainΩin ℝ2and we can prove such kind of ana priorierror estimate. In the part of the estimate, which refers to the discretization of the convective term, we gainh1/2. Although the original problem is linear, the numerical problem becomes nonlinear, due to MUSCL type reconstruction/limiter technique.
Calculus using proximities: a mathematical approach in which students can actually prove theorems
Authors: O’Donovan Richard 
Published: February 2017

Abstract
Teaching and learning calculus are notoriously difficult and the didactic solutions may involve resorting to intuitive but vague definitions or informal gestures offered as proofs. The teaching literature is rife with examples of metaphors, adverb manipulations and descriptions of what happens “just before” the limit. It is then difficult to leave the domain of the mental image, thus losing the training in rigour. The author (with Karel Hrbacek and Olivier Lessmann) has endeavoured a radically different approach with the objective of training students to prove theorems while preserving both intuition and mathematical rigour. Hence we change the mathematical setting rather than the didactic setting. The result (which is a by-product of nonstandard analysis) has been used in several high schools in Geneva – Switzerland – for over ten years.
Using Probe Vehicle Data for Automatic Extraction of Road Traffic Parameters
Authors: Roman Popescu Maria Alexandra 
Published: February 2017

Abstract
Through this paper the author aims to study and find solutions for automatic detection of traffic light position and for automatic calculation of the waiting time at traffic light. The first objective serves mainly the road transportation field, mainly because it removes the need for collaboration with local authorities to establish a national network of traffic lights. The second objective is important not only for companies which are providing navigation solutions, but especially for authorities, institutions, companies operating in road traffic management systems. Real-time dynamic determination of traffic queue length and of waiting time at traffic lights allow the creation of dynamic systems, intelligent and flexible, adapted to actual traffic conditions, and not to generic, theoretical models. Thus, cities can approach the Smart City concept by boosting, efficienting and greening the road transport, promoted in Europe through the Horizon 2020, Smart Cities, Urban Mobility initiative.
