A room simulation tool for thermal comfort control in a bioclimatic building: A real example of use with an optimal controller
Authors: Castilla M. , Bonilla J. , Álvarez J.D. , Rodríguez F. 
Published: March 2014

SummaryA key objective in the European Union climate and energy package for 2020 is the reduction of energy consumption. Buildings are responsible for more that one third of global energy consumption, where heating, ventilation, and air conditioning systems account for more than half of it. In extreme climates, the existing passive measures of bioclimatic buildings are not enough at time to maintain a suitable users’ thermal comfort. However, this thermal comfort must be reached reducing the energy spent by the heating, ventilation, and air conditioning system of the building. Control systems, and more specifically model predictive control, are a suitable way to find a trade‐off between users’ thermal comfort and energy saving. Simulation tools are essential for the efficient and automated testing and validation of these control strategies. This paper presents a simulation tool of an office room from a bioclimatic building, namely, the CDdI‐CIESOL‐ARFRISOL building, to test advanced control strategies against a simulation model, to evaluate them, in terms of users comfort and energy consumption, and to validate them, considering the real room itself. Details about the simulation tool are given, together with the evaluation of its goodness through a real test using a nonlinear model predictive control in an office room of that building.

ABSTRACTObjectiveThis study aims to assess the impact of prenatal diagnosis of de novo apparently balanced chromosome rearrangements (ABCRs) on maternal stress, family functioning and maternal plans of disclosure of genetic information to their child.MethodsAll liveborn children with prenatally detected de novo ABCRs in two Australian states over a 10‐year period (1994–2003) were retrospectively ascertained. Of 39 eligible cases, 16 (41%) participated in the study. Mothers of these children completed a questionnaire using standardized measures to assess family functioning, parental distress, parent–child interaction and child characteristics, with open‐ended questions regarding disclosure.ResultsThe majority of mothers appeared to experience normal levels of parenting stress, quality of parent–child interaction and healthy family functioning. However, most mothers recalled experiencing a significant degree of worry at the time of receiving their prenatal test results, and some mothers (4/15) reported receiving uncertain or conflicting results. Most mothers (13/15) conveyed an understanding of the importance of disclosing this genetic information to their child, and 12/15 conveyed their intention to make this disclosure.ConclusionMost mothers reported normal parenting stress and family functioning, despite experiencing significant worry upon receiving results. Some children are at risk of nondisclosure of their carrier status. © 2014 John Wiley & Sons, Ltd.
Coiling/uncoiling behaviour of sodium polystyrenesulfonate in 2‐ethoxyethanol–water mixed solvent media as probed using viscometry
Authors: De Ranjit , Das Bijan 
Published: March 2014

AbstractPrecise measurements of the viscosities of solutions of sodium polystyrenesulfonate in water and in 2‐ethoxyethanol–water mixtures containing varying amounts of 2‐ethoxyethanol have been performed at 308.15, 313.15, 318.15 and 323.15 K. The intramolecular contributions to the reduced viscosities of the polyelectrolyte solutions were obtained through isoionic dilution maintaining the total ionic strengths of the solutions at polyelectrolyte concentrations of 0.0033, 0.0054 and 0.0080 eq L−1 with sodium chloride. The Huggins constants were also obtained from the experimental data. The influences of the medium and the temperature on the intramolecular contributions to the reduced viscosities as well as on the Huggins constants have been interpreted from the points of view of the conformational characteristics and polyelectrolyte–solvent and polyelectrolyte–polyelectrolyte interactions prevailing in the polyelectrolyte solutions under investigation. Polyion chains were found to coil upon addition of 2‐ethoxyethanol to water or upon an increase of temperature. Thermodynamic affinities for polyelectrolyte–solvent and polyelectrolyte–polyelectrolyte interactions were found to depend greatly on the medium. © 2014 Society of Chemical Industry

Authors: Usui Ayaka , Uruno Aya , Kobayashi Masakazu 
Published: March 2014

AbstractChalcopyrite I‐III‐VI2 compounds are considered as novel potential materials for solar cells. Among the variety of those compounds, CuGaTe2 and AgAlTe2 films were grown by a closed space sublimation method. Crystallinity and stoichiometry of grown films were evaluated by X‐ray diffraction measurements. When CuGaTe2 powder source was used to grow CuGaTe2 films at around 840 °C of the source temperature, stoichiometric CuGaTe2could not be formed. X‐ray diffraction measurements revealed that the deposited material was Cu‐Ga compound. The desorption of Te was compensated by adding elemental Te in the source material. These stoichiometric CuGaTe2 films were achieved when the volume of additional Te was around twice weight of CuGaTe2. On the other hand, growth of AgAlTe2 films could be achieved when the source temperature was 800 °C, and no additional Te was introduced in the source. From X‐ray diffraction measurements, it was found that these two compounds films had strong preference for the (112) orientation on the quartz substrate. (© 2014 WILEY‐VCH Verlag GmbH & Co.

Authors: Aguilar‐Ibañez Carlos , Mendoza‐Mendoza Julio A. , Martinez Juan C. , de Jesus Rubio Jose , Suarez‐Castanon Miguel S. 
Published: March 2014

SummaryA solution to the stabilization problem of a compact set by means of the Interconnection and Damping Assignment Passivity‐Based Control methodology, for an affine nonlinear system, was introduced. To this end, we expressed the closed‐loop system as a Port Hamiltonian system, having the property of almost all their trajectories asymptotically converge to a convenient limit set, except for a set of measure zero. It was carried out by solving a partial differential equation (PDE) or single matching condition, which allows the desired energy level or limit set E to be shaped explicitly. The control strategy was tested using the magnetic beam balance system and the pendulum actuated by a direct current motor (DC‐motor), having obtained satisfactory results.

ABSTRACTObjectiveTo compare outcome of dichorionic–triamniotic (DCTA) triplet gestations with that of a paired cohort of monochorionic–diamniotic (MCDA) twin gestations undergoing laser therapy for treatment of twin‐to‐twin transfusion syndrome (TTTS).MethodsAll DCTA triplets treated at four referral centers between specified dates were included. A matched cohort group of MCDA twin gestations affected by TTTS was used for comparison.ResultsSixteen sets of DCTA triplets treated with laser photocoagulation of placental anastomoses were compared with 32 matched sets of MCDA twins. All of the ‘singleton’ fetuses in the triplet gestations survived to birth and to the end of the neonatal period. There were no differences in single or double survival or the rate of non‐survivors to birth and at age 28 days. A mean 3‐week difference was found in the procedure‐to‐delivery interval in DCTA triplets vs MCDA twins (60 ± 35.8 days vs 83.6 ± 33.2 days; P = 0.029). A mean difference of 3 weeks was also found in the gestational age at delivery in DCTA triplets vs MCDA twins (28.5 ± 3.5 weeks vs 31.9 ± 5 weeks; P = 0.024). A similar post‐laser fetal growth pattern in donors and recipients of both groups was noted.ConclusionsDCTA triplet gestations with TTTS have a similar rate of post‐laser survival but deliver earlier than can be expected for twins treated with laser. These findings have potential implications for the risk of prematurity and long‐term outcomes. Copyright © 2014 ISUOG. Published by John Wiley & Sons Ltd.
Synthesis, Surface Property and Antimicrobial Activity of Cationic Gemini Surfactants Containing Adamantane and Amide Groups
Authors: Zhong Xing , Guo Jianwei , Fu Shuqin , Zhu Dongyu , Peng Jinping 
Published: March 2014

AbstractA series of novel cationic gemini surfactants, namely 1,3‐adamantanedicarboxylic acid bis(alkyldimethyl‐3‐ammoniopropyl amide) dibromide designated as [Ad‐2(amCn)] (n = 12, 14, 16), containing adamantane, two amide groups, and two hydrocarbon chains, were synthesized from 1,3‐adamantanedicarboxylic acid. The surface‐active properties of the surfactants were investigated through surface tension and electrical conductivity measurement. A series of thermodynamic parameters such as standard free energy , enthalpy , and entropy of micellization were evaluated from electrical conductivity measurements in the temperature range from 288 to 308 K. The micellization for [Ad‐2(amCn)] is entropy‐driven at low temperature and enthalpy‐driven at high temperature. Further, the antimicrobial activity of the synthesized gemini surfactants against both Gram‐positive and Gram‐negative bacteria was also investigated, and this study showed that the compound [Ad‐2(amC12)] has excellent antibacterial activity against all studied bacteria.
Gemini Surfactants Foam Formation Ability and Foam Stability Depends on Spacer Length
Authors: Kuliszewska Edyta , Brecker Lothar 
Published: March 2014

AbstractA series of cationic gemini surfactants containing different spacer length were synthesized and analyzed structurally. It was shown that the surface tension (σ) and critical micelle concentration (CMC), which had a maximum for the n‐C4H8 spacer depended on the spacer length. The foaming ability and foam stability are high for the gemini surfactants with short spacers (C2H4 to n‐C4H8), while longer spacers lead to a distinct decrease of these foam parameters. Foaming properties are discussed in terms of configuration and conformation of a surfactant molecule and in relation to micellization state kinetic.
“Family Comes First!” Relationships with family and friends in Italian emerging adults
Authors: Crocetti Elisabetta , Meeus Wim 
Published: March 2014

ABSTRACTWe conducted two studies to examine relationships with family and friends in Italian emerging adults, paying attention to the potential moderating role of gender and occupational status. In Study I, we aimed at capturing emerging adults' perspective on interactions with both family and friends by means of a qualitative approach. Participants were 39 emerging adults (51% males), who were interviewed individually or within a focus group. In Study II, we sought to examine how family and friend importance to identity were related to life satisfaction through a quantitative approach. Participants were 474 (47.3% males) emerging adults who filled a self‐report questionnaire. Overall, findings indicated solid family ties and a strong impact of family importance to identity for life satisfaction. Results were independent of gender and occupational status (university students vs. workers). Thus, findings highlighted that in the Italian context young people's transition to adulthood is strongly intertwined with family relationships.
A SNAPSHOT OF HAPPINESS: PHOTO ALBUMS, RESPECTABILITY AND ECONOMIC UNCERTAINTY IN DAKAR
Authors: Buggenhagen Beth 
Published: March 2014

ABSTRACTYoung women who live in the improvised urban spaces on the outskirts of Senegal's capital city, Dakar, extemporize their respectability in a time of fiscal uncertainty through personal photography. The neighbourhood of Khar Yalla is an improvised, interconnected and multilayered space settled by families removed from the city centre during clean-up campaigns from the 1960s to the 1970s, by families escaping conflict in Casamance and Guinea-Bissau, and by recent rural migrants. As much as Khar Yalla is an improvised neighbourhood, it is also a space of improvisation. When women pose for, display, and pass around portraits of themselves at key moments in their social life, whether in the medium of social networking sites or photo albums, they reveal as much as they conceal the elements of individual and social life. They index their social networks and constitute their urban space not as peripheral, but as central to the lives and imaginations of their siblings and spouses who live abroad. Photographs actively shape and construct urban spaces, which are often loud, unruly and fraught spaces with vast inequalities and incommensurabilities. How women deal with economic and social disparity, within their own families, communities, and globally, is the subject of this article.
‘CREATE YOUR SPACE!’ LOCATING CONTEMPORARY DANCE IN OUAGADOUGOU
Authors: Sieveking Nadine 
Published: March 2014

ABSTRACTSince the turn of the century contemporary dance has been gaining momentum as a pan-African artistic movement in which a new generation of performers is engaging. In contrast to more popular forms of ‘traditional’ or ‘modern’ performance genres, this new movement has evolved within the cosmopolitan urban elite and is driven by processes of professionalization that lead to the creation of new, border-crossing artistic spaces. These spaces are characterized by new boundaries and inequalities, related to various modes of distinction reflecting the shifting grounds of social status – gendered, generational, knowledge-based and economic. Taking an artistic ‘capacity-building’ project targeting female dancers in West Africa as an entry point, the article analyses how the practice of contemporary dance in Ouagadougou leads to the emergence of a translocal social space embedded in a dense network of transnational relations and connected to global art worlds. It is argued that the unequal power relations characterizing the professional art world of contemporary dance reflect the tensions and contradictions of local urban societies in the making and at the same time contribute to a reconfiguration of urban spaces where new forms of rooted cosmopolitanism can be invented.

ABSTRACTThe effect of oxyclozanide, hexachlorophene, nitroxynil, rafoxanide and diamphenethide on malate dehydrogenase activity of homogenates of Fasciola gigantica, Fasciolopsis buski andParamphistomum explanatumwas investigated. The ratio of oxaloacetate reduction to malate oxidation in homogenates of Fasciolagigantica, Fasciolopsis buskiandP. explanatumwas 4·5:1, 3·6:1 and 5·2:1 respectively. Oxyclozanide and rafoxanide at 10−3M inhibited enzyme activity by 100% in homogenates from all three species while hexachlorophene at 10−3M also caused 100% inhibition in homogenates fromFasciola giganticaandP. explanatumbut only 65% of malate oxidation inFasciolopsis buskihomogenates. Nitroxynil at 10−3M produced 60% inhibition inF. buskihomogenates yet had little effect at this concentration on preparations from the other species. Little inhibition was seen with diamphenethide, even at high concentrations. Rapid death ofFasicola giganticaandP. explanatumresultedin vitrowhen 10−3M oxyclozanide, hexachlorophene, nitroxynil or rafoxanide, were added to the incubation medium.Fasciolopsis buskiwas killed by 10−3M oxyclozanide but at this concentration the remaining compounds only caused reduced activity. Assay of malate dehydrogenase following drug treatment invitrofailed to show any appreciable reduction in enzyme activity inFasciola giganticaandP. explanatumbut oxyclozanide and hexachlorophene produced inhibition inFasciolopsis buski. The mode of action of these compounds is discussed.

Published: March 2014

SUMMARYBird-specific ticks do not infest humans and livestock, but these ticks often share their avian hosts with generalist ticks that do. Therefore, their feeding activity may have an impact on the transmission of pathogens outside bird–tick transmission cycles. Here we examined the seasonal feeding activity of the tree-hole tick (Ixodes arboricola) in relation to the activity of its hole-breeding hosts (Parus major and Cyanistes caeruleus). We analysed data on ticks derived from birds, on the abundance of engorged ticks inside nest boxes, and on bird nests that were experimentally exposed to ticks. We observed a non-random pattern of feeding associated with the tick instar and host age. The majority of adult ticks fed on nestlings, while nymphs and larvae fed on both free-flying birds and nestlings. Due to their fast development, some ticks were able to feed twice within the same breeding season. The highest infestation rates in free-flying birds were found during the pre-breeding period and during autumn and winter when birds roost inside cavities. Except during winter, feeding of I. arboricola overlapped in time with the generalist Ixodes ricinus, implying that tick-borne microorganisms that are maintained by I. arboricola and birds could be bridged by I. ricinus to other hosts.
Optimal regulation of a cable robot in presence of obstacle using optimal adaptive feedback linearization approach

Published: March 2014

SUMMARYOptimal path planning of a closed loop cable robot, between two predefined points in presence of obstacles is the goal of this paper. This target is met by proposing a new method of optimal regulation for non linear systems while Dynamic Load Carrying Capacity (DLCC) of the robot is supposed as the related cost function. Feedback linearization is used to linearize the system while Linear Quadratic Regulator (LQR) is employed to optimize the DLCC of the system based on torque and error constraints. Obstacle avoidance for both the end-effector and cables is also considered by the aid of designing an adaptive local obstacle avoidance controller. As a result of linearized nature of the proposed optimal regulation and obstacle avoidance, fast calculation for real time applications is possible. Therefore, formulation of the optimal feedback linearization, together with calculating the DLCC of the robot based on the presented constraints is derived. Finally, a simulation study is performed to study the optimal dynamics and also the maximum DLCC of the cable robot in presence of obstacles. Simulation results are eventually compared with experimental tests conducted on IUST Cable Suspended Robot (ICaSbot) to verify the validity and efficiency of the proposed optimal controllers.
Exploiting personal web servers for mobile context-aware applications

Published: March 2014

AbstractThere is an increasing trend in moving desktop applications to web browsers, even when the web server is running on the same desktop machine. In this paper, we go further in this direction and show how to combine a web server, a web application framework (enhanced to support desktop-like Model–View–Controller interaction) and a context-aware architecture to develop web-based mobile context-aware applications. By using this approach we take advantage of the well-established web paradigm to design the graphical user interfaces (GUIs) and the inherent ability of the web to mash up applications with external components (such as Google Maps). On top of that, since the web server runs on the device itself, the application can access local resources (such as disk space or sensing devices, which are indispensable for context-aware systems) avoiding the sandbox model of the web browsers. To illustrate our approach we show how a mobile hypermedia system has been built on top of our platform.
A goal-based approach to engineering capacity-driven Web services

Published: March 2014

AbstractThis paper discusses a goal-based approach for the engineering of capacity-driven Web services. In this approach, goals are established to first, define the roles that these Web services will play in implementing business applications, second, frame the requirements that will be put on these Web services, and third, identify the processes in terms of business logics that these Web services will carry out. Because of the nature of capacity-driven Web services compared with regular (i.e. mono-capacity) Web services, their engineering in terms of design, development, and deployment takes place in a different way. A Web service that is empowered with several capacities, which are basically separate groups of operations to execute, has to choose one capacity for triggering at run-time. To this end, the Web service takes into account different types of requirements like data and privacy that are put on each capacity that empowers this Web service.
School Interventions After the Joplin Tornado

Published: March 2014

AbstractBackground/ObjectiveTo qualitatively describe interventions by schools to meet children's needs after the May 2011 Joplin, Missouri tornado.MethodsQualitative exploratory study conducted six months after the tornado. Key informant interviews with school staff (teachers, psychologists, guidance counselor, nurse, principal), public health official, and physicians.ReportAfter the tornado, school staff immediately worked to contact every enrolled child to provide assistance and coordinate recovery services. Despite severe damage to half of the city's schools, the decision was made to reopen schools at the earliest possible time to provide a safe, reassuring environment and additional services. An expanded summer school session emphasized child safety and emotional wellbeing. The 2011-2012 school year began on time, less than three months after the disaster, using temporary facilities. Displaced children were bused to their usual schools regardless of their new temporary residence locations. In just-in-time training sessions, teachers developed strategies to support students and staff experiencing anxiety or depression. Certified counselors conducted school-based, small-group counseling for students. Selective referrals were made to community mental health providers for children with greatest needs.ConclusionsEvidence from Joplin adds to a small body of empirical experience demonstrating the important contribution of schools to postdisaster community recovery. Despite timely and proactive services, many families and children struggled after the tornado. Improvements in the effectiveness of postdisaster interventions at schools will follow from future scientific evidence on optimal approaches.KanterRK,AbramsonD.School interventions after the Joplin tornado.Prehosp Disaster Med.2014;29(2):1-4.
