Porous Nickel‐Alumina Derived from Metal‐Organic Framework (MIL‐53): A New Approach to Achieve Active and Stable Catalysts in Methane Dry Reforming
Authors: Karam Leila , Reboul Julien , Casale Sandra , Massiani Pascale , El Hassan Nissrine 
Published: November 2019

AbstractAn Al‐containing MIL‐53 metal‐organic framework with very high surface area (SBET=1130 m2.g−1, N2 sorption) was used as sacrificial template to prepare a nickel‐alumina‐based catalyst (Ni0AlMIL) highly active and stable in the reaction of dry reforming of methane (DRM). The procedure consisted in impregnating the activated (solvent free) MIL‐53 sample with a nickel precursor solution, then calcining the material to remove the organic linkers and subsequently reducing it to form the reduced nickel active phase. At the step of calcination, this procedure results in the formation of a porous uniform spinel phase with Ni nanospecies embedded in the alumina‐based matrix, as deduced from XRD, TPR and TEM analyses. This leads after reduction to a porous lamellar γ‐Al2O3 material with small Ni0 nanoparticles homogeneously dispersed and stabilized within the support. The performances of this catalyst in DRM are better than those of two reference Ni/alumina catalysts prepared for comparison by conventional nickel impregnation of two preformed alumina supports: a first one obtained by calcination of MIL‐53 (AlMIL) and a second one consisting of a commercial γ‐Al2O3 batch (AlCOM). Under steady state conditions at a temperature of 650 °C and a pressure of 1 bar, the higher CH4 and CO2 conversions (till 3 times higher than on Ni0/AlCOM), high catalytic stability (no loss of activity after 13–100 h) and higher selectivity towards DRM (H2:CO products ratio remaining at 1) on Ni0AlMIL compared to the other catalysts is believed to come from the particularly strong interaction between the nickel and alumina phases generated by using the unique high specific surface of the parent MOF support to deposit nickel. This creates an intimate mixing favorable to a persisting interaction of the nickel nanoparticles with the alumina support in the reduced material. The lamellar shape of the γ‐Al2O3 composing the catalyst and its remaining high specific surface may also contribute to the excellent Ni resistance to sintering and in turn to the inhibition of carbon nanotubes formation during the reaction.

AbstractSelection of the friction electrode materials is crucial to the performance of a triboelectric nanogenerator (TENG). In the present study, a metal–organic coordination complex containing organosulfonate counteranions with electron‐donating ability was synthesized through the coordination‐driven self‐assembly approach under mild reaction conditions and was chosen as a positive electrode material to construct a triboelectric nanogenerator, exhibiting high‐output performance with a peak value of short circuit current density of 98.6 μA and an output voltage of 1180 V. As a practical application, it was shown to light up 1488 commercial green LEDs and power an anticorrosion system device to protect metals from corrosion.

Authors: Asnaashari Maryam , Farhoosh Reza , Farahmandfar Reza 
Published: November 2019

AbstractKinetic analysis of gallic acid and methyl gallate in purified Kilka oil was studied in the concentration, range 200–1600 ppm, during autooxidation in Rancimat test at 60°C. The stabilization factor (F), the oxidation rate ratio (ORR), the activity (A), and the mean rate of antioxidant consumption (Winh) were determined. The scavenging activity of 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) radicals decreased in the order gallic acid > methyl gallate > α‐tocopherol > BHT as observed in Kilka oil. There were no significant differences between the effectiveness and strength and activity of gallic acid and methyl gallate at concentrations 200, 400, and 800 ppm. However, above 800 ppm, the activity of methyl gallate became higher than gallic acid, because methyl gallate despite gallic acid did not participate in any chain propagation reactions.
Characterizing the hedging policies of commodity price‐sensitive corporations
Authors: Boroumand Raphaël H. , Goutte Stéphane , Ronn Ehud I. 
Published: November 2019

AbstractMany corporations face price and quantity uncertainty in commodities for which existing futures and options contracts permit corporations to hedge their risks. Finance theory has demonstrated frictions in capital markets are equivalent to risk‐averse decision‐making: Taking prices and volatilities as exogenous, decision‐makers make optimal hedge decisions as a trade‐off between risk and return. In modeling risk aversion, we use mean‐variance and mean‐value at risk‐utility functions. With options quantified as delta‐equivalent futures, using data from the Commodity Futures Trading Commission and gold companies, we document empirically corporations' hedge ratios appear to respond to changing prices and volatilities in accordance with utility‐function prescriptions.

AbstractBCD‐020 is a proposed rituximab biosimilar, which has shown high similarity to rituximab in quality and nonclinical studies in vitro and in vivo.International multicenter clinical trial was conducted to compare efficacy and safety of BCD‐020 and reference rituximab in adult (older than 18 years) patients with indolent lymphomas (follicular lymphoma grade 1‐2, splenic marginal zone lymphoma, and nodal marginal zone lymphoma). Pharmacokinetics, pharmacodynamics, and immunogenicity were also studied.Patients with no previous biologic treatment for lymphoma were randomly assigned 1:1 to receive BCD‐020 or comparator 375 mg/m2 for 4 weeks.Primary study outcome was day 50 overall response rate defined as complete or partial remission. Equivalence range was −20% to 20% for 95% CI for overall response rates difference. Secondary outcomes included adverse events, pharmacokinetics, pharmacodynamics, and immunogenicity.One hundred seventy‐four patients were enrolled, 89 in BCD‐020 arm and 85 in comparator arm. The overall response rate was 44.71% in BCD‐020 arm and 41.89% in comparator arm. Limits of 95% confidence interval (CI) for difference of overall response rates between arms were (−12.62%‐18.24%) showing equivalent efficacy. Sixty‐one (68.54%) and 59 (69.41%) patients had at least one adverse event in BCD‐020 arm or comparator arm, respectively. No unexpected adverse reactions were reported.Antidrug antibodies with no neutralizing activity were detected in two patients in comparator arm on day 14 further declining below detection threshold.Rituximab concentrations had equivalent pattern after intravenous administration of both drugs. Both drugs caused depletion of B‐cells without significant influence on other blood cell lineages.In this study, we showed equivalent efficacy of BCD‐020 and reference rituximab when used in patients with CD20‐positive indolent lymphomas. We also confirmed pharmacokinetic equivalence of BCD‐020 and reference rituximab. Safety profile, pharmacodynamics, and immunogenicity of BCD‐020 were also comparable with those of reference rituximab.

AbstractIssue addressedNoncommunicable chronic disease underlies much of the life expectancy gap experienced by Aboriginal and Torres Strait Islander people. Modifying contributing risk factors; tobacco smoking, nutrition, alcohol consumption, physical activity, social and emotional wellbeing (SNAPS) could help close this disease gap. This scoping review identified and describes SNAPS health promotion programs implemented for Aboriginal and Torres Strait Islander people in Australia.MethodsDatabases PubMed, CINAHL, Informit (Health Collection and Indigenous Peoples Collection), Scopus, Trove and relevant websites and clearing houses were searched for eligible studies until June 2015. To meet the inclusion criteria the program had to focus on modifying one of the SNAPS risk factors and the majority of participants had to identify as being of Aboriginal and/or Torres Strait Islander heritage.ResultsThe review identified 71 health promotion programs, described in 83 publications. Programs were implemented across a range of health and community settings and included all Australian states and territories, from major cities to remote communities. The SNAPS factor addressed most commonly was nutrition. Some programs included the whole community, or had multiple key audiences, whilst others focused solely on one subgroup of the population such as chronic disease patients, pregnant women or youth. Fourteen of the programs reported no outcome assessments.ConclusionsHealth promotion programs for Aboriginal and Torres Strait Islander people have not been adequately evaluated. The majority of programs focused on the development of individual skills and changing personal behaviours without addressing the other health promotion action areas, such as creating supportive environments or reorienting health care services.So What?This scoping review provides a summary of the health promotion programs that have been delivered in Australia for Aboriginal and Torres Strait Islander people to prevent or manage chronic disease. These programs, although many are limited in quality, should be used to inform future programs. To improve evidence‐based health promotion practice, health promotion initiatives need to be evaluated and the findings published publicly.
Factors influencing food service provision decisions in centre‐based early childhood education and care services: Cooks' perspective
Authors: Matwiejczyk Louisa , Mehta Kaye , Coveney John 
Published: November 2019

AbstractIssue addressedConsiderable public effort has been directed at centre‐based childcare as an early childhood education and care (ECEC) setting to promote healthy food‐related behaviours in young children. However, in the real‐world setting, best practice, evidence‐based guidelines are not always well‐translated into usual, day‐to‐day routines. This study aims to understand what factors influence the centre‐based childcare cooks' food and nutrition decisions for children aged 2‐5 years.MethodsSemi‐structured qualitative interviews were conducted with cooks in centre‐based childcare using purposeful maximum variation sampling and data analysed thematically.ResultsFourteen cooks were interviewed from 14 services across South Australia. Central to providing a healthy food environment was expert‐led knowledge and training gained through the workplace over several years and the embodiment of the service's healthy food and nutrition policy, evidenced through menu planning to maintain a focus on healthy eating. Threatening these positive, routine practices and decisions were pressures to modify menus in response to increasing food allergies and changing cultural and family preferences, in the absence of ongoing relevant training and expertise at the system‐level.ConclusionsChildren in ECEC benefit from cooks' commitment to providing nutritious foods; however, the requirements to extend their role to respond to increasing demands without relevant system‐level support and training puts the children at risk of not being exposed to health‐promoting menus and possible errors in providing dietary modifications. ECEC cooks urgently need access to system‐level support and training.So What?Understanding and addressing the barriers experienced by cooks and the complexity of factors that inform their food‐related decision‐making will sustain the implementation of effective, healthy eating guidelines and nutrition practices in ECEC.
Forecasting inflation gap persistence: Do financial sector professionals differ from nonfinancial sector ones?
Authors: Dixon Huw , Easaw Joshy , Heravi Saeed 
Published: November 2019

AbstractThe purpose of the present paper is to investigate forecasted inflation gap persistence using professionals' survey‐based data, differentiating between financial and nonfinancial sectors professionals. We derive the forecasted inflation gap persistence, and using a state‐dependent model, we estimate the nonlinear persistence coefficient of the inflation gap. We distinguish between the pre‐Great Moderation, Great Moderation, and Great Recession periods. Our main results indicate that although the estimates of persistence for gross domestic product inflation largely confirm the results obtained using a linear model, for consumer price index inflation, we find that there is strong evidence for state dependence and time variation. By and large, the results are consistent with the price stability policy pursued in the Great Moderation period and perceived disinflationary pressures during the Great Recession period.
Noninvasive methods of classification and staging of chronic hepatic diseases
Authors: Antony Asir Daniel V. , Ravi R. 
Published: November 2019

AbstractA progressive fatal disease causing more threats to human lives is chronic hepatic disease (CHD). In most of the developing countries, the mortality and morbidity rate have increased due to CHD. Invasive and noninvasive methods are used to measure the pathogenicity of the liver. In this study, ultrasonographic images, clinical findings, and laboratory findings are used to determine the stages of CHD. The stages of CHD are (a) chronic hepatitis, (b) compensated cirrhosis, and (c) decompensate cirrhosis. The histopathological analysis is adopted by the invasive method to conduct a liver biopsy. Results of liver biopsy have shown some kind of complications such as pain after liver biopsy, pneumothorax, bleeding, or puncture of the biliary tree and rarely death due to heavy bleeding. In such situations, noninvasive procedures are used as an alternative for liver biopsy. In this study, Hough‐based histogram‐oriented gradient features are extracted and classified using combined multi‐support vector machine and hidden Markov model classifiers. A large number of feature models containing 42 chronic hepatitis, 49 compensated cirrhosis, and 47 decompensate cirrhosis were selected specifically for the experimental study. The results outperformed using the abovementioned features and have achieved an overall accuracy of about 99% for the normal detector, 91.43% for the chronic hepatitis detector, and 96.72% for the cirrhosis detector.
Impact of a prototyping intervention on middle school students' iterative practices and reactions to failure
Authors: Marks Jenna , Chase Catherine C. 
Published: November 2019

AbstractBackgroundDesign thinking, with its emphasis on iterative prototyping and mantra of “fail early and often,” stands in stark contrast to the typical one‐and‐done, failure‐averse culture of the classroom. Iterative prototyping and fail‐forward mindsets could promote valuable iterative practices and positive reactions to failure, but little research has examined their impact in K‐12 contexts.PurposeIn two studies, we investigated the effect of a brief prototyping intervention on students' iterative knowledge, desires, and behaviors; self‐reported reactions to failure; and performance on a design challenge.Design/MethodStudy participants included 78 and 89 students in grades five and six, respectively. Students in an iterative prototyping condition (Prototype) were taught the process and fail‐forward mindset of iterative prototyping. In a comparative, content‐focused condition (Content), students focused on using science and math concepts in design.ResultsIn both studies, Prototype students gained greater knowledge of iterative prototyping, reported a greater desire to iterate, and engaged in more iterative behaviors on a novel, unsupported design challenge than Content students. In Study 2, students in the Prototype condition reported more positive affect and actions in reaction to failure and produced more successful designs than their Content counterparts. However, regardless of condition, students who iterated earlier created more successful designs.ConclusionsThese studies provide an existence proof that instruction on the iterative prototyping process and mindset can encourage students to try early and often and promote healthier reactions to failure. This work also demonstrated a performance benefit to testing one's design early in the design process.

Published: November 2019

AbstractA multimodal workflow for mass spectrometry imaging was developed that combines MALDI imaging with protein identification and quantification by liquid chromatography tandem mass spectrometry (LC‐MS/MS). Thin tissue sections were analyzed by MALDI imaging, and the regions of interest (ROI) were identified using a smoothing and edge detection procedure. A midinfrared laser at 3‐μm wavelength was used to remove the ROI from the brain tissue section after MALDI mass spectrometry imaging (MALDI MSI). The captured material was processed using a single‐pot solid‐phase‐enhanced sample preparation (SP3) method and analyzed by LC‐MS/MS using ion mobility (IM) enhanced data independent acquisition (DIA) to identify and quantify proteins; more than 600 proteins were identified. Using a modified database that included isoform and the post‐translational modifications chain, loss of the initial methionine, and acetylation, 14 MALDI MSI peaks were identified. Comparison of the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways of the identified proteins was achieved through an evolutionary relationships classification system.

Published: November 2019

The incorporation of evidence derived from multiple research designs into one single synthesis can enhance the utility of systematic reviews making them more worthwhile, useful, and insightful. Methodological guidance for mixed‐methods synthesis continues to emerge and evolve but broadly involves a sequential, parallel, or convergent approach according to the degree of independence between individual syntheses before they are combined.We present two case studies in which we used novel and innovative methods to draw together the findings from individual but related quantitative and qualitative syntheses to aid interpretation of the overall evidence base. Our approach moved beyond making a choice between parallel, sequential, or convergent methods to interweave the findings of individual reviews and offers three key innovations to mixed‐methods synthesis methods:

The use of intersubjective questions to understand the findings of the individual reviews through different lenses,
Immersion of key reviewers in the entirety of the evidence base, and
Commencing the process during the final stages of the synthesis of individual reviews, at a point where reviewers are developing an understanding of initial findings.
Underlying our approach is the process of exploration and identification of links between and across review findings, an approach that is fundamental to all evidence syntheses but usually occurs at the level of the study. Adapting existing methods for exploring and identifying patterns and links between and across studies to interweave the findings between and across reviews may prove valuable.
Identification of the pin offset effect on the friction stir welding (FSW) via Taguchi – Grey relational analysis: A Case study for AA 7075 – AA 6013 alloys
Authors: Kasman Ş. 
Published: November 2019

AbstractThe aim of this work is to present a case study relating to the dissimilar friction stir welding (FSW) ability of AA 7075‐T651 and AA 6013‐T6 by applying pin offset technique. An orthogonal array L18 was conducted to perform the overlapped weld seams using three different values of pin offset, welding speed and tool rotational speed along with two different pin profiles determine the impact of welding parameters on the tensile properties of friction stir welded joints. The nugget zone for each of overlapped weld seams exhibited a complex structure and also, the pin offset and profile also were found to have a great impact on the microstructural evolution of the nugget zone. The ultimate tensile strength, elongation at the rapture and bending strength of welded joints were measured in the ranges of 194–215 MPa, 1.79–3.34 % and 203–352 MPa. From the Taguchi based Grey relational analysis, the optimum welding condition was determined for the welded joint performed using a single fluted pin profile with the zero pin offset, tool rotational speed of 630 min−1 and welding speed of 63 mm/min. Microstructural and macro‐structural observations revealed that welded joints exhibiting lower tensile strength are consistent of various types of defects (e. g. cracks, tunnels and cavities). The fracture location of welded joints was found to be on the heat affected zone and between the heat affected zone and AA 6013‐base metal. The tool and pin wear was not observed during the welding applications
