»Return to what we were« Wirtschaftstraditionen und ökonomische Identität im Zuge der Brexit-Kampagne
Authors: Suckert Lisa
Published: May 2020

Der Ausgang des Brexit-Referendums steht stellvertretend für das Erstarken populistischer Bewegungen, die etablierte Ordnungen in ihrem Kern infrage stellen. Zur Erklärung dieser politischen Verwerfungen werden gemeinhin zwei gegensätzliche Ansätze ins Spiel gebracht, »Cultural Backlash« und »Economic Deprivation«. Dieser Artikel stellt die dichotome Heuristik »Identität versus Ökonomie«, die beiden Ansätzen zugrunde liegt, infrage und entwirft stattdessen das Konzept der kollektiven ökonomischen Identität. Entlang einer diskursanalytischen Untersuchung von rund 400 Dokumenten der Brexit-Kampagne zeige ich, dass die Argumentation der Brexit-Befürworter*innen keinesfalls durch eine Aussparung ökonomischer Aspekte gekennzeichnet war. Im Unterschied zu ihren Kontrahent*innen verknüpften die EU-Kritiker*innen ökonomische Sachverhalte jedoch mit Verweisen auf eine geteilte Vergangenheit und britische Wirtschaftstraditionen. Indem es den Fürsprecher*innen eines EU-Austritts gelang, ökonomische Kritik identitär aufzuladen, konnten sie teils widersprüchliche wirtschaftspolitische Argumente integrieren und ein heterogenes Bündnis mobilisieren.
»Political Correctness« als Sklavenmoral? Zur politischen Theorie der Privilegienkritik
Authors: Schubert Karsten
Published: May 2020

Rechte Intellektuelle berufen sich oft auf Nietzsches Konzept der Sklavenmoral, um damit ihre Kritik an »political correctness« (»PC«) zu untermauern. Diese Verschaltung von Nietzsches Sklavenmoral und »PC«-Kritik ist zutreffend, wie die systematische Analyse ihrer gemeinsamen Elemente zeigt, die zu einer Neubeschreibung von »PC«-Kritik als Privilegienverteidigung führt. Im Gegensatz zur rechtsnietzscheanischen »PC«-Kritik zeigt der linksnietzscheanische Begriff des privilegienkritischen »politischen Urteilens«, dass Politik ein Kampf um Macht und Ansprüche ist, wobei der politische Raum und seine Diskurse immer verregelt und ein Verteilungssystem für Ressourcen und Privilegien sind. Deshalb ist es für eine emanzipatorische Position angebracht, die etablierten Normen kritisch zu hinterfragen und politische Projekte, die sie emanzipativ umschreiben wollen, zu unterstützen. Weil »PC« als emanzipatives politisches Urteilen Privilegien abbaut, ist es kein zu vermeidender Nebeneffekt, sondern ihr vernünftiger Kern, wenn Privilegierte davon eingeschränkt werden. Der Linksnietzscheanismus hilft, nicht von rechter Aggression überrascht zu werden und ihr entsprechend kämpferisch durch strikte Normsetzung zu begegnen.
Comparative Study of Algorithms Metaheuristics Based Applied to the Solution of the Capacitated Vehicle Routing Problem
Authors: Francisco Sandoya Sánchez Fernando , Andrea Letamendi Lazo Carmen , Yamel Sanabria Quiñónez Fanny
Published: May 2020

This chapter presents the best-known heuristics and metaheuristics that are applied to solve the capacitated vehicle routing problem (CVRP), which is the generalization of the TSP, in which the nodes are visited by more than one route. To find out which algorithm obtains better results, there are 30 test instances used, which are grouped into 3 sets of problems according to the position of the nodes. The study begins with an economic impact analysis of the transportation sector in companies, which represents up to 20% of the final cost of the product. This case study focuses on the CVRP for its acronym capacitated vehicle routing problem, analyzing the best-known heuristics such as Clarke & Wright and sweep, and the algorithms GRASP and simulated annealing metaheuristics based.
The Migration, Culture, and Lifestyle of the Paleolithic Ryukyu Islanders
Authors: Fujita Masaki , Yamasaki Shinji , Sawaura Ryohei
Published: May 2020

Roughly 35,000 years ago, hunting-fishing-gathering people occupied the Ryukyu Islands of Japan, a chain of small-sized islands in the western Pacific. There are Paleolithic sites scattered over most of the relatively large islands, thereby suggesting an extensive human dispersal over the sea at least 30,000 years ago. Recent morphological and genetic studies of the human fossils found in this area revealed that Paleolithic occupants might have an affinity with the modern and prehistoric populations of Southeast Asia. Recent excavation of Paleolithic sediments at Sakitari Cave, Okinawa Island, provided a variety of shell artifacts, including beads, scrapers, and fishhooks, and evidence of seasonal consumption of aquatic animals, especially freshwater crabs. The Paleolithic Ryukyu Islanders’ culture and lifestyle, which made use of unique resources, demonstrate behavioral adaptations to living on relatively small islands.
SeDeM-ODT Expert System: A Solution to Challenges in Characterization of Pharmaceutical Powders and Powdered Material
Authors: Khan Amjad , Nazir Shabnam , S. Alyami Hamad , Ullah Aman
Published: May 2020

In the field of pharmaceutical sciences, material characterization has been a focus of research as properties of the powder ingredients govern characteristics of the finished dosage form. It has been a tedious and time-consuming job to develop a correlation between the characteristics of powder material and final dosage form. Extensive experimentation is carried out at different stages of formulation development to optimize the final blend and produce a product fulfilling official requirements. Various approaches have been applied for the purpose with varying degree of applications. SeDeM-ODT expert system is a novel pre-formulation technique developed for characterization of powder material of varying nature. Experimental and quantitative determination of various parameters provides a basis for SeDeM-ODT expert system. The system predicts suitability of powder material (APIs and excipients) for tablet preparation by direct compression technology and disintegration behavior of the resultant dosage form. It provides a basis for selection of excipients, both quantitatively and qualitatively. The present study covers area of powder characterization at pre-formulation level of pharmaceutical product development. SeDeM-ODT expert system reduces lead time for pre-formulation studies and provides formulations with minimum number of excipients. SeDeM-ODT expert system has been successfully applied for material characterization (APIs and excipients) before processing and after processing.
Fontan Operation: A Comprehensive Review
Authors: Syamasundar Rao P.
Published: May 2020

Since the first description of the Fontan operation in the early 1970s, a number of modifications have been introduced and currently staged, total cavopulmonary connection with fenestration has become the most commonly used multistage surgery in diverting the vena caval blood flow into the lungs. The existing ventricle, whether it is left or right, is utilized to supply systemic circuit. During Stage I, palliative surgery is performed, usually at presentation in the neonatal period/early infancy, on the basis of pathophysiology of the cardiac defect. During Stage II, a bidirectional Glenn procedure is undertaken in which the superior vena caval flow is diverted into the lungs at an approximate age of 6 months. During Stage IIIA, the blood flow from the inferior vena cava (IVC) is rerouted into the pulmonary arteries, typically by an extra-cardiac conduit along with a fenestration, generally around 2 years of age. During Stage IIIB, the fenestration is closed by transcatheter methodology 6–12 months after Stage IIIA. The evolution of Fontan concepts, the indications for Fontan surgery, and the results of old and current types of Fontan operation form the focus of this review.
The Function of Seven Transmembrane Receptors in the Cardiovascular System and Their Role in the Development of Cardiomyopathy
Authors: Kubale Valentina , Prozorowska Ewelina , Glocová Kristýna , Slater Lucy , Sian Rutland Catrin
Published: May 2020

The G-protein-coupled receptors (GPCRs, also called seven-transmembrane receptor, 7TMRs, or heptahelical receptor) are a conserved family of seven transmembrane receptors which are essential not only in the healthy heart and blood vessels but also in for treatment and therapy of cardiovascular disease and failure. Heart failure is a global leading cause of morbidity and death and as such understanding 7TMRs, their functions, structures and potential for therapy is essential. This review will investigate the roles of the receptors in the healthy functioning cardiovascular system, and in cardiac disorders with an emphasis in cardiomyopathy. It will also explore the role of autoimmunity and autoantibodies against the G-protein-coupled receptors in cardiomyopathy.
Radiolabelled Nanoparticles for Brain Targeting
Authors: Sethi Chopra Dimple
Published: May 2020

Tumors like glioblastoma are inaccessible due to blood brain barrier. The permeability of radioisotopes can be improved by conjugating them with nanoparticles. The most common malignant adult brain tumor is glioblastoma, which has very poor patient prognosis. The mean survival for highly proliferative glioblastoma is only 10–14 months despite an aggressive radiotherapy and chemotherapy following debulking surgery. β− particle emitters like 131I, 90Y, 186/188Re, and 177Lu have been coupled with nanoparticles and used for treatment of glioblastoma. These radiopharmaceutical compounds have resulted in a stabilization and improvement of the neurological status with minimal side effects. Similarly, α particle emitters like 213Bi, 211At, and 225Ac are an innovative and interesting alternative. Alpha particles deliver a high proportion of their energy inside the targeted cells within a few micrometers from the emission point versus several millimeters for β− particles. Thus, α particles are highly efficient in killing tumor cells with minimal irradiation of healthy tissues and permits targeting of isolated tumor cells. This has been confirmed by subsequent clinical trials which showed better therapeutic efficacy and minimal side effects, thus opening a new and promising era for glioblastoma medical care using α therapy.
Humanismo y nuevo ateísmo: experiencias y propuestas de una minoría educativa
Authors: Bandini Gianfranco
Published: May 2020

The research intends to trace a profile of two twentieth-century movements — Humanism and New Atheism — which, from an educational point of view, constitute an interesting and original minority. Although both studies and activities of undeniable educational interest have been produced, they have not yet been put at the centre of specific research. They currently represent one of the most innovative aspects of the current debate on the purpose of education both at school and in the family. These are movements that are not only academic or theoretical research, but they represent a varied social sample which in some countries, moreover, is no longer a small minority, but clearly affects public opinion and even parts of the political agenda.The analysis of the recent history of movements that we can define of an “atheist world” indicates a clear trend line: their positions seem destined to be an integral part of the debates on current educational issues, particularly because the positions they expressed — with their constant anchoring to scientific culture and rational dialogue — seem suitable to face the difficult challenges of globalisation and the tensions that cross pluralistic societies.
Analytics for Action: Assessing effectiveness and impact of data informed interventions on online modules
Authors: Hidalgo Rafael , Evans Gerald
Published: May 2020

La efectividad del uso de las analíticas de aprendizaje es un tópico de gran relevancia en la literatura sobre el tema. Una revisión sistemática reciente encontró 689 artículos en este campo (Larrabee Sonderlund et al., 2019). Sin embargo, solamente 11 de los 689 artículos destacan el potencial de las intervenciones basadas directamente en el análisis de los datos disponibles. La Open University UK (OU) es una de las pocas instituciones que desarrolla e implementa sistemáticamente un marco de uso de las análiticas a gran escala. Este documento revisa el impacto de una parte de este marco: el proceso de Analytics for Action (A4A). Utilizando datos del curso académico 2017-18, revisamos los comentarios de los participantes y las intervenciones acordadas como parte  del proceso.El proceso A4A implica la capacitación práctica del personal, seguida de reuniones sucesivas en las que se discuten los datos cuando el curso ya está disponible en línea. El objetivo del proceso es ayudar a los educadores a planificar y realizar intervenciones  basadas en la evidencia, con el fin de mejorar  la retención y satisfacción de los estudiantes. Los resultados de este estudio indican que los participantes están satisfechos con la capacitación y que las reuniones de apoyo están ayudando a proporcionar nuevas perspectivas sobre los datos. El alcance y la naturaleza de las intervenciones varían ampliamente, desde la no intervención hasta intervenciones que abarcan múltiples presentaciones (cohortes) del curso. En algunos casos, medir el impacto real de las acciones tomadas requerirá el análisis de los datos de otras presentaciones. El trabajo también presenta hallazgos que indican que todavía hay margen para mejorar el seguimiento de las acciones acordadas, el apoyo brindado a los equipos académicos para implementar tales acciones y la evaluación final del impacto en los resultados y satisfacción de los estudiantes.
Twins assessing their own and parental intelligence: Examining the raters’ agreement and the effect of raters’ and targets’ gender
Authors: Bratko Denis , Pocrnić Martina , Butković Ana
Published: May 2020

The goal of this study was to explore the raters’ agreement and the effect of raters’ and targets’ gender on self- and parental intelligence assessments in the sample of Croatian twins. Twins were asked to assess their own and their parents’ overall intelligence, as well as specific abilities from the Gardner’s theory of multiple intelligences. Data was analysed to explore: i) twins’ agreement in parental assessments and behavioural genetic analysis of the overall intelligence estimates; ii) gender differences in self- assessments; and iii) raters’ and targets’ gender effects on parental assessments. The twins’ mean correlation in their assessments of overall parental intelligence was .60. The differences between monozygotic and dizygotic twin correlations were nonsignificant for all of the estimated abilities, and model fitting analysis indicates that hypothesis about genetic effect on parental assessment of intelligence should be rejected. The hypotheses about males’ higher self-assessments for overall intelligence and for the masculine types of abilities - logical-mathematical, body-kinesthetic and spatial abilities - were confirmed. For the feminine types of abilities - verbal/linguistic, inter- and intra- personal intelligences - there were no significant gender effects. Both target and rater effect were found for the parental estimates of intelligence. Fathers were estimated higher on overall intelligence, logical-mathematical, body-kinesthetic and spatial abilities, while mothers were estimated higher on interpersonal and intrapersonal intelligence. The effect of the raters’ gender was found for overall intelligence as well as for inter- and intra- personal intelligences, where males gave higher estimates of parental intelligences than females.
New mobilities and psychology: Why are we still not on the move?
Authors: Glăveanu Vlad P.
Published: May 2020

The new mobilities paradigm has been influential within the social sciences for the past two decades. And yet, psychology is undoubtably slow to incorporate mobility as a key lens through which to consider its subject area. In this editorial, I will make the case that we would benefit greatly from focusing more on personal, collective and psychological mobilities and the kinds of conceptual, methodological and practical challenges they raise. To illustrate this, I briefly discuss the notions of self and identity, learning, and imagination and creativity. Final conclusions are offered regarding a late but welcomed ‘mobilities turn’ in psychological science.
CETA et mobilité de la main-d’oeuvre hautement qualifiée : une réelle innovation dans la gestion migratoire transatlantique?
Authors: Debuisson Aurélie
Published: May 2020

Le XXIe siècle a été témoin d’une accélération de la mobilité des travailleurs temporaires hautement qualifiés de par l’abolition de toute une série d’entraves au commerce international, dont les accords de libre-échange se veulent les garants. Le commerce et la gestion migratoire sont guidés par des logiques d’action différentes. Il importe d’évaluer si le législateur, tant canadien qu’européen, a veillé à atteindre un équilibre entre ces deux domaines de plus en plus connectés dans les législations en vigueur de part et d’autre de l’Atlantique. Signé en octobre 2016 entre le Canada, l’Union européenne et ses États membres, l’Accord économique et commercial global, plus connu sous son acronyme anglais CETA, fait son entrée dans la gamme des instruments de gestion migratoire. L’hypothèse de recherche consiste à déterminer si le chapitre 10 du CETA, reprenant les dispositions concernant l’admission temporaire de certains travailleurs, s’inscrit dans une volonté de changement global des politiques migratoires et dans une nouvelle perception de ces dernières. Peut-on utiliser le terme d’innovation à tous les niveaux ? Si, sur le plan économique, le pari semble tenu, le CETA s’insérant dans la lignée des accords antérieurs de libre-échange, le bilan semble plus mitigé lorsque le travailleur hautement qualifié n’est plus uniquement considéré comme l’équivalent d’un bien ou d’un service. L’analyse approfondie des dispositions du chapitre 10 démontre qu’il n’existe pas de réponse innovante, apportée par le CETA, en ce qui concerne la gestion de la fuite des cerveaux. Cette dernière problématique serait en effet régulée si les questions de la libre circulation des travailleurs, de l’accès à la résidence permanente, du regroupement familial ou encore des droits de ces travailleurs avaient fait l’objet d’une attention particulière lors de l’adoption de ce nouvel accord. Force est de constater qu’elles demeurent les grandes oubliées.
Meal planning as a strategy to support healthy eating
Authors: Fernandez Melissa A. , Desroches Sophie , Marquis Marie , Provencher Véronique
Published: May 2020

Meal planning is cited in the latest version of Canada’s Dietary Guidelines as one of four important food skills that help individuals choose, purchase and prepare healthy snacks and foods on a regular basis for themselves and members of their household. While meal planning is often mentioned as a strategy to overcome the main barrier to healthy eating, lack of time, it may also assist individuals reduce stress related to mealtimes and increase frequency of family meals. Although, there is relatively sparse literature that meal planning confers benefits to the diet, there is a history of evidence indicating that it helps manage dietary restrictions related to specific diseases (e.g., diabetes), which can translate into helping the general public consume more fruits and vegetables, while consuming fewer processed foods. In 2013 Health Canada implemented a one-year communication campaign to promote meal planning to Canadian parents as a strategy to increase home-based food preparation and family meals. The campaign evaluation found that awareness was associated with greater odds of having more positive attitudes towards meal planning. However, more than half of parents also reported that lack of time was a major barrier for meal planning. Dietitians can recommend meal planning as a viable strategy to help the public and patients overcome barriers to healthy eating. However, they will likely also need to provide guidance through education and tools to overcome barriers related to meal planning.
TUER ENTRE NOUS
Authors: Bélanger David , Bérard Cassie
Published: May 2020

Cet article s’intéresse au « retour » que fait le régionalisme, celui idyllique du début du xxe siècle, dans la littérature québécoise récente. Ce retour, plus précisément, rend compte de crimes dans un univers sachant difficilement les contenir. Dans Le discours sur la tombe de l’idiot (2008) de Julie Mazzieri, Le chasseur inconnu (2014) de Jean-Michel Fortier et Trois fois la bête (2015) de Zhanie Roy, nous rencontrons effectivement des meurtres, sans que les infrastructures ne permettent de les traiter : ni enquêteur, ni médecin légiste, ni quelque instance judiciaire n’apparaissent dans ces fictions. Une telle représentation du crime permet de conceptualiser ces oeuvres comme des « actualisations à distance », c’est-à-dire que le mouvement de retour s’avère sciemment problématisé selon les conceptions éthiques contemporaines. Par le biais des questions de l’origine et de l’autorité, comme interrogations au coeur de ces fictions critiques de l’idéal régionaliste, cet article entend éclairer ce geste de création important dans la production récente.
ÉCRIRE LA PÉRIPHÉRIE AU QUÉBEC
Authors: Kirouac Massicotte Isabelle
Published: May 2020

Dans cette contribution, l’auteur poursuit la réflexion de Mathieu Arsenault
sur la ruralité trash à partir de la lecture de La déesse des mouches à
feu de Geneviève Pettersen et de Kuessipan de Naomi Fontaine.
Souhaitant s’éloigner d’une vision quelque peu misérabiliste du lieu périphérique,
elle s’attache à démontrer que l’écriture de la périphérie rend signifiants certains
non-lieux et qu’elle aménage des espaces de liberté liés à la ruralité ou encore aux
modes de vie marginaux. La cartographie des lieux périphériques — et le discours qui
la crée — fonde la régionalité de ces oeuvres en même temps qu’elle permet de mettre
au jour certaines facettes de cette tendance littéraire, dont elle tente d’esquisser
les contours en fin de parcours.
David William Smith
Authors: Alexander Christopher
Published: May 2020

David William Smith, the first Surveyor General of Upper Canada, the second largest landowner ever in Pickering Township, and, at one time, the owner of most of the land that is now Ajax, was Lieutenant Governor John Graves Simcoe’s most consistent administrator and the principal architect and implementer of the province’s new and complex land-granting system. However, his many accomplishments have been largely overlooked. This article seeks to return Smith to his rightful place as a key shaper in early Upper Canada’s fortunes.
A Season of Unusual Depression
Authors: Jarvis Eric
Published: May 2020

The Panic of 1857 had a significant impact on Toronto, since the economic depression that followed affected the city’s government, fiscal health, and public services. Thus, it can be used as a case study of how a 19th century Panic and depression could change a city’s society, even to the point of “crisis”. Using city records and newspapers, this analysis focuses on city debt management, tax collection and cutbacks on such new services as police, fire-fighting and street lighting. In addition, it discusses how a Panic could transform democratic politics by decreasing the number of persons eligible for city council and the franchise. The mayor ceased to be an elected position. Such “reforms” would be used again following the more famous reforms of the 1890s depression. In fact, a pattern can be discerned: city democracy was increased by boom times and decreased by depressions.

du contexte propres à chaque génération, ainsi que des visions personnelles de la ville
quant à ses institutions et activités artistiques.
Modernist Ultimate Thule
Authors: Windsor Liscombe Rhodri
Published: May 2020

À partir de la Seconde Guerre mondiale, le gouvernement fédéral canadien s’est de plus en plus intéressé à ses régions nordiques et arctiques, au « pays du nord, puissant et libre », imaginé dans le texte anglais de l’hymne national du Canada. Ces terres lointaines ont fourni les ressources minérales nécessaires à certaines opérations militaires et ont servi de sites à des installations stratégiques. Le développement de nouvelles infrastructures comme l’Alaska Highway – traversant davantage le territoire canadien qu’américain – a également exposé la précarité de l’autonomie canadienne. Les stratégies pour la canadianisation du nord ont été renforcées par la guerre froide et les politiques de développement, surtout sous le régime Diefenbaker. Des architectes comme Peter Dickinson et Ralph Erskine ont été invités à préparer les plans de nouvelles colonies, notamment Frobisher Bay (1958) et Resolute (1963), où l’on a déployé une technologie de construction de pointe à partir d’objectifs de planification issus du mouvement moderne. Cet épisode illustre la collusion ironique entre le mouvement moderne et les moteurs de la modernité que celui-ci avait l’intention de reformuler.

Here are the polyps: in situ observations of jellyfish polyps and podocysts on bivalve shells
Authors: van Walraven Lodewijk , van Bleijswijk Judith , van der Veer Henk W.
Published: May 2020

Most Scyphozoan jellyfish species have a metagenic life cycle involving a benthic, asexually reproducing polyp stage and a sexually reproducing medusa stage. Medusae can be large and conspicuous and most can be identified using morphological characteristics. Polyps on the other hand are small, live a cryptic life attached to hard substrates and often are difficult or impossible to distinguish based on morphology alone. Consequently, for many species the polyp stage has not been identified in the natural environment. We inspected hard substrates in various habitats for the presence of Scyphozoan polyps. Three polyps were found on Dogger Bank, Central North Sea, attached to the inside of the umbo of empty valves of the bivalves Mactra stultorum and Spisula subtruncata. One polyp was accompanied by four podocysts. With this knowledge, the inside of bivalve shells washed ashore in Oostende (Belgium) was inspected and supposed podocysts on the inside of empty valves of Cerastoderma edule and Spisula elliptica were found. Polyps and podocysts were identified to species level by 18S rDNA and mitochondrial COI sequencing. The three polyps found on Dogger Bank all belonged to the compass jellyfish Chrysaora hysoscella. One podocyst from the Oostende beach also belonged to this species but another podocyst belonged to Cyanea lamarkii. These are the first in situ observations of C. hysoscella and C. lamarckii polyps and podocysts in the natural environment. Mactra, Cerastoderma and Spisula species are abundant in many North Sea regions and empty bivalve shells could provide an abundant settling substrate for jellyfish polyps in the North Sea and other areas. Several new strategies to increase the detection of polyps on bivalve shells are presented.

Water Logging in South-Western Coastal Region of Bangladesh: Causes and Consequences and People’s Response
Authors: Awal M. A. , Islam A. F. M. Tariqul
Published: May 2020

Aim: Since decades, a major part of south-western coastal region of Bangladesh is being affected by water logging – a problem related to climate change along with some manmade activities. Therefore, the study was conducted to assess the causes and consequences of this problem and highlights the responses of affected people to attract policy planners’ intention for taking proper intervention.

Place and Duration of Study: The study was conducted in the Laboratory of Plant Ecology, Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, Bangladesh.

Methodology: Qualitative and quantitative techniques have been applied to collect and analyze both the primary and secondary sources of data from various waterlogged areas of south west Bangladesh.

Results: There is no single or a few factors are responsible for creating water-logging problem rather it is a combination of several factors and their cumulative effects over time. It is revealed from the analysis of primary and secondary sources of information that death of Mathavanga River in the 20th century, execution of Coastal Embankment Project since 1960’s, withdrawing water flow to the Padma River through operating the Farakka barrage after independent of Bangladesh, improper management of rivers, faulty land-use by influential people in the areas, monsoon downpour etc are major causes of the problem. The silted up river systems in area could not drain monsoon rain that occurred even for a couple of days. The consequences brought to inundate hundred thousand hectares of cultivable land unsuitable for crop production. More than one million people are directly affected in the areas and the number is gradually increasing over the years. Water stagnancy around the settlement areas remains 6 to 9 months in a year and many places became permanently waterlogged. The affected people have no other way out but to live with water. The congested water is polluted with salinity, chemical effluents with heavy metals, household debris’s and related other pollutants. Source of safe drinking water is destroyed. Therefore incidences of waterborne and skin diseases are increased. People are living with greatest inhumanity as food, shelter, sanitation, communications, educations and other prime needs are tremendously challenged. Many people lost their occupations and became destitute, some altered their livelihood to much lower grades, and many of them are forced to migrate to city areas. The marooned people demanded to the authority to declare their places as an affected area and sought the government intervention to bring an end to the crisis through operating the Tidal River Management plan and excavating or re-excavating of associated rivers, channels and rivulets.

Conclusion: The authority need to pay keen attention to the issue and should take proper initiative to mitigate the water-logging problem permanently to save people living in the south western coastal region of Bangladesh.
Microstructure‐Enhanced Inverse Magnetostrictive Effect in Fe–Co Alloy Wires
Authors: Yamazaki Takahiro , Katabira Kenichi , Narita Fumio , Furuya Yasubumi , Nakao Wataru
Published: May 2020

Polycrystalline magnetostrictive alloys with a combination of high stiffness and strength and large magnetostriction are desirable for various smart applications, including energy harvesters and microscale sensors and actuators. However, the in‐depth understanding of the microstructure–property relationship in these alloys is still limited due to the complexity of their grain geometry, multi‐objective design requirements, and the few experimental verifications available. Herein, the correlation between the power generation properties and microstructures controlled by heat treatment in Fe29Co71 (at%) alloys is investigated. As a result, the Fe–Co alloy annealed at 893 K for 5 h, exhibiting fine grains with a {110} <001> orientation, shows excellent characteristics, such as an ultimate tensile strength of 832 MPa, magnetostriction of 117 ppm, and an output voltage density of 130 μV/mm3. The enhancement in power generation performance is due to the increase in magnetostriction, accompanying the refinement of crystal grains by recrystallization. The newly demonstrated linear relationship between grain size and magnetostriction (λs = 80.0 D−1/2 + 133) in this study can be a useful design guideline for further improvement in magnetostrictive materials.

Herein, a metal matrix composite (MMC) composed of 316L stainless steel and 20% in volume of tungsten carbides (WC), fabricated by laser cladding (LC) is considered. LC is an additive manufacturing technique, characterized by ultrafast cooling rates and limited diffusion, thus giving rise to out‐of‐equilibrium microstructures. The microstructure of the MMC is found to consist of partially dissolved WC well distributed in an austenitic matrix reinforced by a network of reaction carbides. Those mixed reaction carbides are formed from a liquid enriched in W and C due to the dissolution of the original WC in contact with the molten metal during deposition. Distribution, chemical composition, crystallographic features, and stability of the different phases are characterized in details by combining electron microscopy, electron backscattered diffraction, and dilatometry. This combination of techniques allows to distinguish among M6C, M23C6, M4C, and WC1–x carbide, belonging to the Fe–W–C system and all exhibiting a face‐centered cubic lattice. Moreover, results of reverse thermal analyses are considered together with microstructural data to elucidate the genesis of this complex microstructure, differentiating the phases formed in the melt pool, in the vicinity of partially dissolved WC and in the heat‐affected zone between two successive tracks.

Many researchers have tried to use metallic glass alloys in bipolar plates because of their unique properties such as their higher mechanical strength and corrosion resistances, recently. Thin‐film metallic glasses (TFMGs), herein, are coated on an austenitic stainless steel (AISI 316L) plate to enhance the corrosion properties of the metallic bipolar plate. A crystallized alloying target with the composition Zr63.9Al10Cu26.1 and a grain size of less than 1 μm is prepared by consolidating the amorphous powder at 800 °C for 30 min. Also, TFMGs are coated on the AISI 316L plate using direct current (DC) magnetron sputtering system. The contact resistance of the TFMG is decreased by 24 mΩ cm2 by controlling the surface roughness of the AISI 316L plate. The corrosion current densities of the TFMGs are less than 1 μA cm−2 under both anodic and cathodic conditions, and there are no changes of the current density in the range of potentials of 0.6–1.2 V which corresponds to the operating conditions of a proton exchange membrane (PEM) fuel cell. Based on this result, it is believed that these TFMGs can be a potential candidate coating materials for metallic bipolar plate in PEM fuel cell.

Wearable interfaces are central to multiple healthcare and wellness strategies encompassing diet and nutrition, personalized health monitoring, and performance optimization. Specifically, the advent of flexible electronic formats coupled with microfluidic interfaces has resulted in sophisticated conformal devices for biofluid sampling and quantification. Here, a complementary approach is presented to wearable sensing by using a large‐scale, conformal, distributed format that relies on the use of biomaterial‐based inks to print and stabilize deterministic patterns of biochemical reporters with high resolution. Colorimetric devices can vary in size and a sensing T‐shirt based on a colorimetric pattern is developed to illustrate the utility that such formats can add to the wearable interface space. Image analysis allows parameter variation to be tracked in real‐time, yielding a map‐like format of distributed biophysical response.

Published: May 2020

Origami/kirigami‐inspired 3D assembly approaches have recently attracted attention for a variety of applications, such as advanced optoelectronic devices and biomedical sensors. The results reported here describe an approach to construct classes of multiple foldable 3D microstructures that involve deformations that typical conductive materials, such as conventional metal films, cannot tolerate. Atomically thin graphene sheets serve as folding hinges during a process of 2D to 3D conversion via a deterministic buckling process. The exceptional mechanical properties of graphene enable the controlled, geometric transformation of a 2D precursor bonded at selective sites on a prestretched elastomer into folded 3D microstructures, in a reversible manner without adverse effects on the electrical properties. Experimental and computational investigations of the folding mechanisms for such types of 3D objects reveal the underlying physics and the dependence of the process on the thickness of the graphene/supporting films that define the hinges.

By virtue of their narrow emission bands, near‐unity quantum yield, and low fabrication cost, metal halide perovskites hold great promise in numerous aspects of optoelectronic applications, including solid‐state lighting, lasing, and displays. Despite such promise, the poor temperature tolerance and suboptimal quantum yield of the existing metal halide perovskites in their solid state have severely limited their practical applications. Here, a straightforward heterogeneous interfacial method to develop superior thermotolerant and highly emissive solid‐state metal halide perovskites is reported and their use as long‐lasting high‐temperature and high‐input‐power durable solid‐state light‐emitting diodes is illustrated. It is found that the resultant materials can well maintain their superior quantum efficiency after heating at a temperature over 150 °C for up to 22 h. A white light‐emitting diode (w‐LED) constructed from the metal halide perovskite solid exhibits superior temperature sustainable lifetime over 1100 h. The w‐LED also displays a highly durable high‐power‐driving capability, and its working current can go up to 300 mA. It is believed that such highly thermotolerant metal halide perovskites will unleash the possibility of a wide variety of high‐power and high‐temperature solid‐state lighting, lasing, and display devices that have been limited by existing methods.

There is rising interest on low‐k dielectric materials based on porous metal–organic frameworks (MOFs) for improved electrical insulation in microelectronics. Herein, the concept of MOF dielectric sensor built from a single crystal of HKUST‐1 is demonstrated. Guest encapsulation effects of polar and non‐polar molecules are studied, by monitoring the transient dielectric response and AC conductivity of the crystal exposed to different vapors (water, iodine, methanol, and ethanol). The dielectric properties are measured along the <100> crystal direction in the frequency range of 100 Hz to 2 MHz. The dielectric data show the efficacy of MOF dielectric sensor for discriminating the guest analytes. The time‐dependent transient response reveals dynamics of the molecular inclusion and exclusion processes in the nanoscale pores. Since dielectric response is ubiquitous to all MOF materials (unlike DC conductivity and fluorescence), the results demonstrate the potential of dielectric MOF sensors compared to resistive sensors and luminescence‐based approaches.

Several virtual screening models are proposed to screen small molecules only targeting primary miRNAs without selectivity. Few attempts have been made to develop virtual screening strategies for discovering small molecules targeting mature miRNAs. Mature miRNAs and their specific target mRNA can form unique functional loops during argonaute (AGO)‐mediated miRNA–mRNA interactions, which may serve as potential targets for small‐molecule drug discovery. Thus, a loop‐based and AGO‐incorporated virtual screening model is constructed for targeting the loops. The previously published studies have found that miR‐214 can target ATF4 to inhibit osteoblastic bone formation, whereas miR‐214 can target TRAF3 to promote osteoclast activity. By using the virtual model, the top ten candidate small molecules targeting miR‐214‐ATF4 mRNA interactions and top ten candidate small molecules targeting miR‐214‐TRAF3 mRNA interactions are selected, respectively. Based on both in vitro and in vivo data, one small molecule can target miR‐214‐ATF4 mRNA to promote ATF4 protein expression and enhance osteogenic potential, whereas one small molecule can target miR‐214‐TRAF3 mRNA to promote TRAF3 protein expression and inhibit osteoclast activity. These data indicate that the loop‐based and AGO‐incorporated virtual screening model can help to obtain small molecules specifically targeting miRNA–mRNA interactions to rescue bone phenotype in genetically modified mice.
