How do virtual corporate social responsibility dialogs generate value? A case study of The Unilever Sustainable Living Lab
Authors: Jurietti Emanuela , Mandelli Andreina , Fudurić Morana 
Published: February 2017

AbstractToday, companies have an increasing need to integrate stakeholders in CSR processes. The emergence of web 2.0 platforms and social media not only facilitates stakeholder interaction, but has also led to a new form of interaction opportunity called co‐creation. We use a single case study of The Unilever Sustainable Living Lab to empirically test the virtual CSR dialogs framework, which is the main contribution of the paper. More specifically, we examine the extent to which CSR value can be generated by incorporating specific social media platforms that allow co‐creation among users and companies. The findings indicate dialog characteristics were critical when designing co‐creation dialogs on sustainability. Additionally, we confirmed the link between dialog characteristics and community identification and CSR expectations. However, the model failed to illustrate the difference between opportunities of co‐creation, i.e., dialog characteristics, and actual co‐creation experience.

A power efficient buck‐boost converter by reusing the coil inductor for wireless bio‐implants
Authors: Barati Mahdi , Yavari Mohammad 
Published: February 2017

SummaryIn this paper, a buck‐boost converter circuit for wireless power transfer via inductive links in bio‐implantable systems is presented. The idea is based on reusing the power receiver coil to design a regulator. This method employs five switches to utilize the coil inductor in a frequency other than the power‐receiving signal frequency. Reusing the coil inductor decreases the on‐chip regulator area and makes it suitable for bio‐implants. Furthermore, in the proposed technique, the regulator efficiency becomes almost independent of the coil receiving voltage amplitude. The proposed concept is employed in a buck‐boost regulator, and simulation results are provided. For a 10 MHz received signal with the amplitude variation within 3 ~ 6 V and with the converter switching rate of 200 kHz, the achieved maximum efficiency is 78%. The proposed regulator can also deliver 10 μA to 4 mA to its load while its output voltage varies from 0.6 to 2.3 V. Simulations of the proposed converter are performed in Cadence‐Spectre using TSMC 0.18 μm CMOS technology. Copyright © 2017 John Wiley & Sons, Ltd.
Strategic science for eating disorders research and policy impact
Authors: Roberto Christina A. , Brownell Kelly D. 
Published: February 2017

AbstractScientific research often fails to have relevance and impact because scientists do not engage policy makers and influencers in the process of identifying information needs and generating high priority questions. To address this scholarship‐policy gap, we have developed a model of Strategic Science. This research approach involves working with policy makers and influencers to craft research questions that will answer important and timely policy‐related questions. The goal is to create tighter links between research and policy and ensure findings are communicated efficiently to change agents best positioned to apply the research to policy debates. In this article, we lay out a model for Strategic Science and describe how this approach may help advance policy research and action for eating disorders.
Endogenous analgesic effect of pregabalin: A double‐blind and randomized controlled trial
Authors: Sugimine S. , Saito S. , Araki T. , Yamamoto K. , Obata H. 
Published: February 2017

AbstractBackgroundConditioned pain modulation (CPM) is widely used to measure endogenous analgesia, and a recent study indicated that drugs that act on endogenous analgesia are more effective in individuals with lower CPM. Recent animal studies have indicated that pregabalin activates endogenous analgesia by stimulating the descending pain inhibitory system. The present study examined whether the analgesic effect of pregabalin is greater in individuals with lower original endogenous analgesia using CPM.MethodsFifty‐nine healthy subjects were randomly assigned to either a pregabalin group or a placebo group, and 50 of them completed the study. CPM was measured before and after pregabalin or placebo administration. The correlation of initial CPM to change in CPM was compared between the pregabalin and placebo groups.ResultsInitial CPM was significantly correlated with the change in CPM in the pregabalin group (r = −0.73, p < 0.0001) but not in the placebo group (p = 0.56) (difference in correlation coefficients between groups; p = 0.004). Furthermore, the initial CPM significantly affected the change in CPM in the pregabalin group but not in the placebo group (pregabalin group: adj R2 = 0.51, p < 0.001, y = −0.54x + 2.98; placebo group: p = 0.56, significant difference in regression slopes; p = 0.015). These results indicate that pregabalin has a higher endogenous analgesic effect in individuals with lower original endogenous analgesia.SignificanceThe analgesic effect of pregabalin depends on the original endogenous analgesia status. Its effect on conditioned pain modulation (CPM) was stronger for subjects with lower original endogenous analgesia, suggesting that the mechanism of pregabalin involves the improvement of endogenous analgesia.

AbstractA sensitive electrochemical sensor was fabricated based on ceria‐graphene oxide nanoribbons composite (CeO2‐GONRs) for an antiviral drug, entecavir (ETV). It was characterized by SEM, EDAX, AFM, IR and Raman spectroscopic techniques. The electrochemical behaviour of ETV was investigated by cyclic voltammetric, differential pulse voltammetric (DPV), linear sweep voltammetric (LSV) and square wave voltammetric (SWV) methods at CeO2‐GONRs modified glassy carbon electrode. Good linearity was observed between the peak current and concentration of ETV in the range of 0.51 ‐ 100 μM with a detection limit of 0.042 μM in DPV method, 2.1 – 61.1 μM with a detection limit of 0.7 μM in LSV method and 0.1 ‐ 80 μM with a detection limit of 68.1 nM in SWV method. The proposed sensitive DPV method was successfully applied for the determination ETV in tablets and biological samples.

The effect of concentration rate of Ni(NO3)2/Co(NO3)2 preparation solution on crystalline structure, morphology and supercapacitive performance was investigated systematically. Experimental found that the morphology and composition of NiCo LDH was highly depend on the Ni2+/Co2+ molar ratios of preparation solution; and the obtained Ni0.76Co0.24 LDH materials showed small nanosheet size and uniform distribution on carbon fiber electrode. Ni0.76Co0.24 LDH electrode was evaluated for supercapacitor application, which revealed a high specific capacitances of 2189.8 and 1908.8 F g−1 at the current density of 1 and 30 A g−1 respectively and a good cycle stability, retaining 70.3 % of the initial capacitance after 20000 charge and discharge cycles at 50 A g−1. Moreover, the Ni0.76Co0.24 LDH electrode exhibits a high energy density of 76 Wh Kg−1 at a power density of 250 W Kg−1 and a high power density of 7500 W Kg−1 at energy density of 66 Wh Kg−1. The as‐prepared Ni0.76Co0.24 LDH as positive electrode for asymmetric supercapacitor exhibits excellent energy density of 4.1 Wh Kg‐1 at a power density of 4000 W Kg‐1
A Novel Exoelectrogenic Bacterium Phylogenetically Related to Clostridium sporogenes Isolated from Copper Contaminated Soil
Authors: Deng Huan , Xue Hongjing , Zhong Wenhui 
Published: February 2017

AbstractAs a vast pool of micro‐organisms, soil might contain diverse exoelectrogenic bacteria. However, soil source exoelectrogenic bacteria were seldom studied. We isolated one exoelectrogenic bacterial strain (designated as R6) from a microbial fuel cell (MFC) operated with copper contaminated soil. Based on phylogenetic analysis of the 16S rRNA gene sequences, along with physiological and morphological characteristics, strain R6 was identified as Clostridium sporogenes, which was not reported as an exoelectrogenic bacterium before. Cyclic voltammetry measurements revealed that strain R6 transferred electrons to anode through direct contact rather than by generating electron shuttles. The voltage curve generated by strain R6 showed that the bacteria was resistant to 10 mg L−1 Cu2+, but were inhibited with more than 25 mg L−1 Cu2+. This study highlights the discovery of more soil source exoelectrogenic bacterial species.

Published: February 2017

AbstractUnderstanding the lithiation–delithiation of the Mg–Li alloy during the absorption–desorption of hydrogen is essential for the development of Li‐ion batteries with MgH2 as a negative electrode. Tuning the hydrogenation–dehydrogenation kinetics and thermodynamics of the Mg–Li alloy could also be helpful to develop a lightweight material for on‐board hydrogen‐storage applications. Single‐phase Li3Mg7 (the highest % of lithium compound) was prepared by ball milling of LiH and MgH2 as precursors of Li and Mg followed by dehydrogenation at 400 °C under dynamic vacuum conditions. The cyclic hydrogenation–dehydrogenation behavior of the intermetallic was studied in detail. During hydrogenation, Li3Mg7 was delithiated to LiH and MgH2, whereas during dehydrogenation, LiH and MgH2 were lithiated to form the Li3Mg7 phase along with a Mg–Li solid solution. The hydrogenation–dehydrogenation kinetics of pristine Li3Mg7 were found to be slow. The hydrogenation–dehydrogenation kinetics were remarkably improved by doping with ZrCl4 as a catalyst. The activation energy and the thermodynamic parameters of the uncatalyzed and catalyzed alloy were evaluated, and the results were compared.

ObjectivesThe aim of this study was to investigate whether structural and process characteristics of memory assessment services (MASs) are associated with outcomes (changes in patients' health‐related quality of life (HRQL), carers' HRQL and carers' burden) over the first 6 months following the first appointment.MethodsData from 785 patients referred to 69 MASs and 511 of their lay carers, collected at the first appointment and 6 months later. Data on MAS characteristics were collected using a questionnaire at baseline. We used multilevel linear regression models to explore the associations of patients' HRQL and carers' outcomes with structural and process characteristics of MASs. Analyses were conducted on the full sample of patients and carers, and separately on those patients diagnosed with dementia.ResultsNone of the structural (skill mix, workload, volume, provision of clinical assessments and provision of psychosocial support) or process (waiting time, length and number of appointments, anti‐dementia drug use and psychosocial interventions use) characteristics included in the analyses were associated with patients' or carers' outcomes at 6 months, apart from the presence of allied health professionals (AHPs), which was associated with a DEMQOL score 2.7 points higher. When only those with a diagnosis of dementia were considered, the association with presence of AHPs was no longer observed.ConclusionsApart from involving AHPs, alterations to the way MASs are structured or function appear unlikely to improve their effectiveness in improving patients' and carers' HRQL. It is possible that the characteristics of MASs may influence patients' and carers' experience, but this was not studied. Copyright © 2017 John Wiley & Sons, Ltd.

ABSTRACTBackgroundThe rates and factors associated with the return to work of head and neck cancer survivors from low‐ and middle‐income countries, such as India, are largely unknown.MethodsWe conducted a preliminary cross‐sectional survey of 250 consecutive eligible head and neck cancer survivors (age <60; ≥6 months posttreatment) to identify return to work rates and sociodemographic, clinical, and quality of life (QOL; European Organization for Research and Treatment of Cancer Quality of Life Questionnaire‐Core 30‐questions [EORTC‐QLQ‐C30] and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire‐Core 30 Head and Neck 35‐questions [EORTC‐QLQ–H&N35]) correlates.ResultsIn our cohort, 92.4% of the patients were employed pretreatment, 65.6% and 81.2% returned to work at 6 months posttreatment and by the time of the survey (median follow‐up 19 months), respectively. Family structure (<2 male children, p = .008; eldest child age <20 years, p = .04), a higher level of education (vocational or professional training, p = .013) and female sex (p = .001) were associated with higher return to work. Head and neck cancer survivors who returned to work had better global quality of life (QOL; p = .014) and less coughing (p = .001) but more problems related to sticky saliva (p = .004).ConclusionFurther studies are needed to address the large unmet needs regarding identification and amelioration of barriers to return to work for head and neck cancer survivors in low‐ and middle‐income countries, such as India. © 2017 Wiley Periodicals, Inc.

Interaction of Two Unequal Turbulent Jets with Different Temperature
Authors: Samira Louaifi‐Hamaili , Amina Mataoui 
Published: February 2017

AbstractThis paper examines the control and heat transfer process of the mixing of a strong jet and a weak jet. The control of the jet diffusion may be required in many devices such as cooling systems, combustors, gas turbines, heating or cooling surfaces, cooling problem techniques, mixing flows, etc. A steady three‐dimensional problem is solved by the finite volume method using RANS modeling. The validation confirms that both RSM and k‐ε realizable models predict more accurately this flow configuration than the standard k‐ε model. A parametric study is conducted on the basis of ratios of the momentum of the two jets. Due to the Coanda effect, the deviation of the weak jet has been highlighted for several momentum ratios. In the fully developed flow region, after the confluence point, the structure of a single jet flow is recovered. However, the point of maximum velocity is shifted toward the side of the strong jet. For a given velocities ratio of 0.25, the temperatures ratio between the two jets is checked. The location of maximum temperature of the jet is almost constant for diverse values of 0.8 ≤ λT ≤ 1. The location of the point of maximum temperature varies linearly according to λT.
Physical Effects of Variable Fluid Properties on Laminar Gas Microconvective Flow
Authors: Kumar Rajan , Mahulikar Shripad P. 
Published: February 2017

AbstractThe physical effects of variable fluid properties on heat transfer and frictional flow characteristics of laminar gas microconvective flow are investigated in this research. The fully developed flow through a microtube is studied numerically by using 2D continuum‐based governing equations. The physical effects induced due to variations in gas density with pressure and temperature, and gas viscosity, thermal conductivity, and specific heat with temperature are analyzed. Numerical results reveal that the heat transfer and frictional flow characteristics of laminar gas microflow are drastically affected by these physical effects. Hence, this research suggests that these physical effects need to be well considered in the applications of laminar gas microconvection based on large temperature gradients, for example, the design of microchannel heat sinks, and the flow cannot be generally considered as a constant property flow, as in conventional channels.
Numerical Investigations on the Advantage of Nanofluids under DDMC in a Lid‐Driven Cavity
Authors: Reddy Nithish , Murugesan K. 
Published: February 2017

AbstractDouble diffusive mixed convection in a lid‐driven cavity filled with Cu–water nanofluid is studied in detail. Various numerical experiments are conducted under horizontal thermal and concentration gradients. Flow equations were solved in velocity vorticity form using Galerkin's weighted residual finite element method. The Maxwell‐Garnett model and Brinkman models are applied to predict the thermal conductivity and dynamic viscosity of the nanofluid, respectively. The effectiveness of a nanofluid on heat transfer enhancement with respect to change in Richardson number has been studied at different Reynolds numbers for variation in particle volume fraction from 0 to 0.05. Similarly, the effect of buoyancy ratio on heat and mass transfer is presented for buoyancy ratio in the range of −25 to 25. Detailed contour plots comparing the streamlines, temperature, concentration with and without nanoparticles were presented for all the range of parameters considered. The role of particle concentration and change in type of nanofluid has been reported. The average Nusselt number has increased in all the cases where as the Sherwood number slightly decreased with an increase in particle volume fraction. The Ag–water nanofluid showed better improvement in heat transfer characteristics compared to other nanofluids for all Reynolds numbers and particle volume fractions.

AbstractThe objective of this research was to introduce and evaluate derived models under simultaneous water and nitrogen deficit stress conditions and consequently calibrating their parameters for basil. Therefore to do so, in order to introduce and evaluate derived models under simultaneous water and nitrogen deficit stress conditions, derived models from the composition of Mitscherlich–Baule (MB) for nutrient stress conditions and the models of Feddes (F), van Genuchten (VG), recommended exponential (EXP) and Homaee (H) for water stress conditions and also the composition model of Liebig–Sprengel (LS) for nutrients and the model of Feddes (F) for water stress conditions were presented and evaluated. This experiment was conducted with four irrigation water quantity levels of 120, 100, 80 and 60% of crop water requirement and four nitrogen fertilizer levels of 100, 75, 50 and 0% of fertilizer requirement based on a soil fertility test with three replicates. The results indicated that of the evaluated models, based on calculated statistical indices, the derived models of MB‐EXP, MB‐F, MB‐VG and MB‐H (mentioned above) had the best fitting on the measured data, respectively, compared to actual data. The results of calculated statistics to compared models based on the different nitrogen and water irrigation levels indicated that MB‐EXP and MB‐F using nRMSE statistics were 2.78 and 3.64, and EF statistics of both was 0.99% and they showed the highest accuracy in estimating basil yield.

Published: February 2017

ObjectiveThe present study aimed to investigate the characteristics of macular telangiectasia type 1 (Mac tel type 1) using spectral‐domain optical coherence tomography angiography (OCTA) and compare them with the characteristics of mild diabetic macular edema (DME), to provide a new objective method for quick clinical diagnosis and treatment.MethodsA retrospective comparative analysis of 9 Mac tel type 1, 15 DME, and 15 normal eyes was performed using fluorescein angiography, spectral‐domain optical coherence tomography, and OCTA. The morphological changes, retinal vessel density, and nonperfused areas were evaluated using split‐spectrum amplitude‐decorrelation angiography algorithm.ResultsOCTA revealed obvious saccular capillary telangiectasia and loss of parafoveal vascular density of Mac tel type 1. However, a number of line segment hyperreflective signals around the macula and more distinct nonperfusion in DME were observed. The quantitative foveal avascular zone mean area in Mac tel type 1 was larger than that in the normal eyes (0.40 ± 0.06 mm2 vs. 0.88 ± 0.19 mm2, P < 0.001). However, the area in DME (1.52 ± 0.38 mm2) was larger than that in Mac tel type 1 (P < 0.001), and the foveal zone area in DME (1.127 ± 0.05 mm2) was also lager than it in Mac tel (P < 0.05). The vascular density of the superficial layer reduced in both Mac tel type 1 and DME (compared with normal eyes). The difference between Mac tel type 1 (49.56 ± 5.23)% and DME(44.58 ± 3.82)% was significant in the superficial capillary layer (P < 0.01). The vascular density of the retinal deep layer also reduced in both Mac tel type 1 and DME (compared with normal eyes). The difference between Mac tel type 1 (53.78 ± 7.36)% and DME (53.64 ± 4.96)% was no significant in this layer (P > 0.05).ConclusionMorphological differences between Mac tel 1 and DME can be observed on OCTA. Superficial vascular density and non‐perfusion area may serve as a quantitative method to identify them. Lasers Surg. Med. 49:225–232, 2017. © 2017 Wiley Periodicals, Inc.
