Endovascular treatment of coronary subclavian steal syndrome complicated with STEMI and VF: A case report and review of the literature
Authors: Haj Bakri Mouaz , Nasser Maher , Al Saqer Lean 
Published: November 2018

Key Clinical MessageEndovascular treatment of coronary subclavian steal syndrome is usually successful and safe. However, it might be lethally complicated, such as our case of STEMI and ventricular fibrillation during stent deployment. Early diagnosis of subclavian stenosis, intermittent dilations of balloons during stent deployment, and choosing the accurate stent size are suggested to avoid such complications.

Published: November 2018

AbstractThe local electroless deposition of gold on pyrite is studied by scanning electrochemical microscopy (SECM). The SECM and additional SEM experiments provide kinetic and mechanistic insights on the local galvanic replacement of pyrite by gold. We evidence that individual gold nanoparticles or full coverage of gold on the pyrite surface can be obtained by controlling either the deposition time or the flux of gold ions electrogenerated at the ultramicroelectrode. We also studied the influence of ferric ions, known to be implied on gold etching and pyrite corrosion and therefore, on the overall process of gold deposition on pyrite. We then demonstrate that the presence of ferric ions significantly modifies i) the thermodynamic of the gold electrodissolution, ii) the process of adsorption of auric ions on pyrite in the first instants, iii) the number of nucleation sites on the pyrite surface and, iv) the structure of the deposited gold layer.

AbstractAlthough safe and low‐cost aqueous supercapacitors have gained great attention, their narrow operation voltage significantly limits their widespread applications. Here, we demonstrate a high‐voltage and high‐capacitance aqueous symmetric supercapacitor by using polyaniline‐derived carbon nanorods as the electrodes and a highly concentrated water‐in‐salt [lithium bis(trifluoromethane sulfonyl) imide dissolved in water] electrolyte. The resultant supercapacitor is able to work with a wide operation voltage window of 2.2 V and shows a high specific capacitance of 44 F g−1 at a current density of 1 A g−1. Moreover, it exhibits a superior rate capability (73 % capacitance retention upon increasing current density from 1 to 10 A g−1). Consequently, the favorable combination of high specific capacitance, wide operation voltage window, and excellent rate capability enable the device to have comparable energy and power densities to those of commercial non‐aqueous supercapacitors.
Ionic Liquid Stabilized Gelatin–Lignin Films: A Potential UV‐Shielding Material with Excellent Mechanical and Antimicrobial Properties
Authors: Mehta Mohit J. , Kumar Arvind 
Published: November 2018

AbstractSignificant research is currently underway to develop environmentally friendly UV‐shielding materials. Herein, we have constructed choline citrate (a biobased ionic liquid, IL) stabilized homogeneous gelatin–lignin UV‐shielding films with excellent antimicrobial and mechanical properties. The synthesis procedure of the films is less energy demanding, one pot, and sustainable in nature. Prepared films were characterized by mechanical and thermal analysis using UTM and TGA, respectively. ATR‐IR and PXRD was employed to explore the possible formation of H‐bonding between biopolymers and the IL and the change in crystallinity in films after addition of IL to the gelatin–lignin matrix. Surface morphology of prepared films has been studied using optical microscope, AFM, and field emission SEM (FE‐SEM). Optical properties of prepared films were measured using UV/Vis spectroscopy. Antimicrobial activity of the prepared films was tested against Bacillus subtilis. Prepared biofilms showed a sun‐protection factor (SPF) of up to ≈45.0, large elongation ≈200 %, and tensile strength ≈70 MPa, which are as good as those values exhibited by organic polymeric films, indicating a promising renewable‐resources‐based material for UV light blocking.

Published: November 2018

AbstractChagas disease also know as American Trypanosomiasis (AT) is a tropical parasitic disease endemic in South America, is caused by Trypanosoma cruzi, which is transmitted by the blood‐sucking insect vectors called triatomine bugs. Quinoline alkaloids from the root extract of Waltheria indica are known to possess antitrypanosomal activity. Waltherione F, one of those alkaloids, was synthesised in 5 steps in 11 % overall yield. We report here the first X‐ray crystallographic confirmation of the structure of Waltherione F 3. A key step in the sequence utilised the Conrad–Limpach synthesis for the formation of the quinolin‐4(1H)‐one ring system. Our synthetic strategy was designed to enable the modification of the 2‐ and 3‐positions of the scaffold, allowing the generation of a diverse library of analogues to support our on‐going medicinal chemistry program that is looking for new agents to tackle this devastating disease.
Colloidal Quantum Dot Arrangement Assisted by Perylene Bisimide Self‐Assembly
Authors: Yamauchi Mitsuaki , Masuo Sadahiro 
Published: November 2018

AbstractColloidal semiconductor nanocrystals, so‐called quantum dots (QDs), are attractive as molecular‐like smart nanomaterials, and their emission and optoelectronic properties in the dispersed state have been actively studied. The construction of supramolecular structures composed of multiple QDs, however, is still challenging. Here, a new strategy to form supramolecular QD structures via self‐assembly of perylene bisimide (PBI) dyes is demonstrated. In a mixed solution, QDs and PBI undergo time‐dependent fusion to form an isolated colloidal QD‐PBI complex or a unique QD‐PBI co‐aggregate composed of QDs arranged along a sheet‐like PBI nanostructure, and these dramatically different supramolecular structures can be controlled by the solvent polarity.
Sustainable development and supply chain coordination: The impact of corporate social responsibility rules in the European Union food industry
Authors: Stranieri Stefanella , Orsi Luigi , Banterle Alessandro , Ricci Elena Claire 
Published: November 2018

AbstractCorporate social responsibility has become a strategic asset for food firms to demonstrate their good environmental conduct. The aim of this paper is to investigate the role of the implementation of corporate social responsibility activities on the reorganization of vertical relationships within food supply chains. Applying content analysis techniques to the Global Reporting Initiative reports, we collected qualitative data on investments in environmentally friendly options, the adoption of standards, stakeholder engagement, information searches, impact‐monitoring activities, and chain coordination to transform it into quali‐quantitative data. We find that the variables affecting chain coordination relate to the presence of sourcing standards, effort in discussing with chain partners ways to prevent and manage chain environmental impacts, and costs related to stakeholder feedback collection. The results of the analysis confirm corporate social responsibility as a strategic tool to improve supply chain relationships through an augmented vertical coordination and to integrate environmental policy.
Wildflower strips enhance pollination in adjacent strawberry crops at the small scale
Authors: Ganser Dominik , Mayr Barbara , Albrecht Matthias , Knop Eva 
Published: November 2018

AbstractWildflower strips (WFS) are increasingly used to counteract the negative consequences of agricultural intensification. To date, it is poorly understood how WFS promote flower visitation and pollination services in nearby insect‐pollinated crops. We therefore ask whether WFS enhance pollination service in adjacent strawberry crops, and how such an effect depends on the distance from WFS. Over 2 years, we examined the effects of experimentally sown WFS compared to grassy strips on pollination services in adjacent strawberry (Fragaria ananassa) crops across a total of 19 study sites. Moreover, we examined flower visitation, species richness and community composition of the most important insect pollinator taxa at different within‐field locations varying in distance to WFS. We found increased pollination services at the edge of WFS compared to locally reduced pollination services at the center, which resulted in no significant difference in seed set between WFS and control fields. Total flower visits and species richness of pollinators were higher in WFS than in adjacent strawberry fields. Moreover, wild bee visitation was enhanced in adjacent strawberry crops near WFS compared to field centers, and intermediate at field edges near grassy strips. Our study demonstrates that diverse WFS can increase wild bee visitation and pollination services in the field edges of adjacent strawberry crops, but that overall visitation and pollination services do not increase. Moreover, our findings show that major pollinator taxa exhibit distinct responses, resulting in a shift of pollinator community composition as a function of distance to WFS with direct effects on crop pollination. Our results that WFS enhance rather than reduce crop pollination services near WFS should distract possible concerns by farmers that WFS may locally absorb rather than export crop pollinators. Considering the spatial restricted enhancement of wild bees and associated pollination services we suggest to establish WFS in the center of crop fields.
Local adaptation in mainland anole lizards: Integrating population history and genome–environment associations
Authors: Prates Ivan , Penna Anna , Rodrigues Miguel Trefaut , Carnaval Ana Carolina 
Published: November 2018

AbstractEnvironmental gradients constrain physiological performance and thus species’ ranges, suggesting that species occurrence in diverse environments may be associated with local adaptation. Genome–environment association analyses (GEAA) have become central for studies of local adaptation, yet they are sensitive to the spatial orientation of historical range expansions relative to landscape gradients. To test whether potentially adaptive genotypes occur in varied climates in wide‐ranged species, we implemented GEAA on the basis of genomewide data from the anole lizards Anolis ortonii and Anolis punctatus, which expanded from Amazonia, presently dominated by warm and wet settings, into the cooler and less rainy Atlantic Forest. To examine whether local adaptation has been constrained by population structure and history, we estimated effective population sizes, divergence times, and gene flow under a coalescent framework. In both species, divergence between Amazonian and Atlantic Forest populations dates back to the mid‐Pleistocene, with subsequent gene flow. We recovered eleven candidate genes involved with metabolism, immunity, development, and cell signaling in A. punctatus and found no loci whose frequency is associated with environmental gradients in A. ortonii. Distinct signatures of adaptation between these species are not associated with historical constraints or distinct climatic space occupancies. Similar patterns of spatial structure between selected and neutral SNPs along the climatic gradient, as supported by patterns of genetic clustering in A. punctatus, may have led to conservative GEAA performance. This study illustrates how tests of local adaptation can benefit from knowledge about species histories to support hypothesis formulation, sampling design, and landscape gradient characterization.

Published: November 2018

Carbon materials with a high specific surface area, large pore size, high electrical conductivity, and high chemical stability are regarded as promising electrode materials for supercapacitors. With the advantages of using ionic liquids precursors and biomass‐based precursors for the synthesis of carbon materials, nitrogen‐doped porous activated carbon materials with an ultrahigh surface area (up to 3638 m2 g−1), a desirable pore size (up to 2.44 nm), and a high content of 10.38 at % oxygen and 1.14 at % nitrogen are prepared from alginic‐based protic polyanion ionic liquids (APPILs) using the KOH activation method. The specific structural properties of the as‐prepared carbon materials can be tuned by the nature of organic bases in the APPILs and carbonization conditions. When used as electrode materials for symmetric supercapacitors in 6 m KOH electrolytes, the obtained carbon material shows a significantly high gravimetric capacitance of up to 354 F g−1 at a current density of 0.1 A g−1. Moreover, the assembled supercapacitor delivers a relatively high energy density of 12.3 W h kg−1 and a power density of 26 W kg−1, as well as a high cycling stability of 95% capacitance retention after 10 000 cycles.
Zoogeomorphological behaviours in fish and the potential impact of benthic feeding on bed material mobility in fluvial landscapes
Authors: Rice Stephen , Pledger Andrew , Toone Julia , Mathers Kate 
Published: November 2018

AbstractForaging by benthivorous fish can affect bed material mobility and sediment flux. This paper collates evidence of benthic feeding effects at local scales and evaluates the possibility that large numbers of foraging fish, each of which accomplishes a small amount of geomorphic work when feeding, may have a cumulative effect across river systems. A first synthesis of research from several disciplines provides a deeper understanding of how fish disturb and condition bed materials with implications for sediment mobility. To evaluate the spatial extent of benthic feeding and therefore the potential for it to have a large‐scale effect, the distribution of benthivorous fish is established across a large river network. After quality control, the dataset yields a comprehensive set of fish community information based on over 61 000 individuals and 30 species at 176 sites. The factors that are likely to mediate foraging and its geomorphological effectiveness are considered. A novel scoring system that incorporates three key controls (fish feeding behaviour, fish abundance and fish body size) is then applied across the river network to predict where geomorphologically effective benthic feeding is feasible and its possible relative magnitude. Our results demonstrate, for the first time, that the potential for zoogeomorphic impacts is widespread but variable in space as a function of community composition and the abundance of key benthivores. An initial calibration against measured field impacts suggests that benthic feeding may cause measurable geomorphological disturbance at more than 90% of sites in this large network. Together, previous work and this unique analysis suggest that benthic feeding is sufficiently effective and extensive to warrant additional research. Investigating the role of benthivorous fish in fluvial geomorphology is important because it may yield results that challenge the assumption that biota are irrelevant sources of energy in geomorphological systems. Key research questions and a roadmap to facilitate progress are identified. © 2018 John Wiley & Sons, Ltd.
When stock futures dominate price discovery
Authors: Aggarwal Nidhi , Thomas Susan 
Published: November 2018

AbstractThis paper revisits the role of leverage in price discovery, using one of the most liquid single‐stock futures (SSFs) markets in the world. Price discovery is analysed as a dynamic intraday process. We find that the information share of the SSFs is 55% during news arrivals. It increases to 61%, when the news is negative and the futures is preferred because of short‐sales restrictions on the spot. A partial equilibrium analysis predicts that the trade‐off between leverage and market liquidity determines price discovery across securities. These predictions are validated by empirical evidence.
Stability, Stimuli‐Responsiveness, and Versatile Sorption Properties of a Dynamic Covalent Acylhydrazone Gel
Authors: Fang Haobin , Chen Lingyu , Zeng Lihua , Yang Zujin , Zhang Jianyong 
Published: November 2018

AbstractGel adsorbents are promising for pollutant removal from the wastewater. Herein, an acylhydrazone gel is developed from acylhydrazide‐terminated pentaerythritol (PAT) and 2,4,6‐triformylphloroglucinol (TFP) based on dynamic covalent acylhydrazone chemistry. PAT‐TFP gel is stable under various conditions, while it shows reversible Cu2+ adsorption and desorption. PAT‐TFP gel is studied as a versatile adsorbent for the capture of a range of (bulky) organic contaminants and heavy metal ions from aqueous solutions. Fast and good adsorption capacities are achieved for various dyes (rhodamine B and methyl orange), amines (aniline, p‐chloroaniline, 4‐methylaniline, and p‐aminobenzoic acid), phenols (phenol, 1‐naphthol, p‐methylphenol, and bisphenol A), and metal ions (Cu2+, Cr3+, and Hg2+). The maximum adsorption capacity is 107.5 mg g−1 for Cu2+ and the equilibrium adsorption time is 30 min. PAT‐TFP gel can be regenerated efficiently and used repeatedly.
Evapotranspiration response to multiyear dry periods in the semiarid western United States
Authors: Rungee Joseph , Bales Roger , Goulden Michael 
Published: November 2018

AbstractAnalysis of measured evapotranspiration shows that subsurface plant‐accessible water storage (PAWS) can sustain evapotranspiration through multiyear dry periods. Measurements at 25 flux tower sites in the semiarid western United States, distributed across five land cover types, show both resistance and vulnerability to multiyear dry periods. Average (±standard deviation) evapotranspiration ranged from 660 ± 230 mm yr−1 (October–September) in evergreen needleleaf forests to 310 ± 200 mm yr−1 in grasslands and shrublands. More than 52% of the annual evapotranspiration in Mediterranean climates is supported on average by seasonal drawdown of subsurface PAWS, versus 29% in monsoon‐influenced climates. Snowmelt replenishes dry‐season PAWS by as much as 20% at sites with significant seasonal snow accumulation but was insignificant at most sites. Evapotranspiration exceeded precipitation in more than half of the observation years at sites below 35°N. Annual evapotranspiration at non‐energy‐limited sites increased with precipitation, reaching a mean wet‐year evapotranspiration of 833 mm for evergreen needleleaf forests, 861 mm for mixed forests, 558 mm for woody savannas, 367 mm for grasslands, and 254 mm for shrublands. Thirteen sites experienced at least one multiyear dry period, when mean precipitation was more than one standard deviation below the historical mean. All vegetation types except evergreen needleleaf forests responded to multiyear dry periods by lowering evapotranspiration and/or significant year‐over‐year depletion of subsurface PAWS. Sites maintained wet‐year evapotranspiration rates for 8–33 months before attenuation, with a corresponding net PAWS drawdown of as much as 334 mm. Net drawdown at many sites continued until the dry period ended, resulting in an overall cumulative withdrawal of as much as 558 mm. Evergreen needleleaf forests maintained high evapotranspiration during multiyear dry periods with no apparent PAWS drawdown; these forests currently avoid drought but may prove vulnerable to longer and warmer dry periods that reduce snowpack storage and accelerate evapotranspiration.
