FATIGUE CRACK GROWTH AND FATIGUE FRACTURE MORPHOLOGY OF RECYCLED RUBBER POWDER–FILLED NR/BR BLEND COMPOUND
Authors: Hassim D. H. Abang Ismawi , Abraham Frank , Summerscales John 
Published: January 2020

ABSTRACTThe effect of two different types and particle sizes (micronized cryo-ground 74 μm or ambient-ground 400 μm) of recycled rubber powder (RRP) was studied during fatigue crack growth (FCG) in a natural rubber/butadiene rubber (NR/BR) compound using a fracture mechanics approach. Absolute and relative hysteresis losses using single-edge notch tensile specimens were determined with a displacement-controlled strain compensating for the permanent set of the samples throughout the FCG experiments. Differences in relative hysteresis loss showed that additional energy dissipation, due to multiple new crack surfaces at the crack tip, contributes to the FCG of the RRP compounds. At higher tearing energy, beside other factors affecting the FCG performance of the RRP compounds, both higher absolute and relative hysteresis loss are slightly detrimental to the crack growth rates. At lower tearing energy, the larger RRP-filled compound showed slower, but not significant, different crack growth rates than the NR/BR control compound. Fracture morphologies for NR/BR and RRP-filled compound were associated with different fracture surface topographies at various tearing energies, which revealed the dependency of the crack growth microstructure on the tearing energies.

Sound production as a cultural practice
Authors: Cichocki Piotr 
Published: January 2020

Referring to a notion of cultural practice understood as a constitution of social identity and meaningful everyday performance, this paper questions the practice of music production outside the technological centers of the global North. The author traces relations between the global standards of studio work and the case of “record culture” in Mzuzu, Malawi. On a tangible level, the production of sound and music in Mzuzu is bricolage, a creative combination of varied devices and means within an economy of scarcity.However, sound production in its intangible dimension reveals itself as a practice of mediation between material and immaterial spheres. Spatially, it combines local aesthetics with globally unified technologies. This mediation gathers different temporalities (old, “tribal” rhythms and digital sounds) with cosmologies (i.e. invocation to holy ghosts with gospel music, in contrast to local possession cults). Moreover, people embody many of these practices as opposed to expressing them discursively. As an embodied practice, the production contains social, non-discursive memory while, at the same time, it has a potential for construction of social worlds. Hence, sound production constitutes a sense-making practice that establishes relations between musicians, listeners, and other social actors.

Réflexions concernant le recours aux fiches réflexives en ergothérapie visant le développement de la démarche réflexive des stagiaires
Authors: Brousseau Martine 
Published: January 2020

Un dispositif pédagogique en ergothérapie a été mis en place pour soutenir les stagiaires dans le développement de leurs compétences reliées à la démarche réflexive. Il a été proposé à ceux-ci de rédiger un carnet de stage contenant des fiches réflexives durant leurs stages. Or, la mise en place de l’utilisation des fiches réflexives s’est avérée difficile étant donné qu’elle dépendait de l’initiative de l’étudiant ou de la volonté du superviseur de stage à y avoir recours. Suite à ce constat, une évaluation du recours à ce dispositif pédagogique a été faite. Le présent article expose les résultats de cette démarche d’évaluation. Cette démarche visait à 1. Décrire le bien-fondé du recours aux journaux réflexifs en ergothérapie ; 2. Documenter les retombées de l’écriture réflexive en ergothérapie ; 3. Apprécier sommairement le recours aux fiches réflexives ; 4. Décrire des éléments à considérer pour l’appréciation de la qualité des réflexions. La démarche d’évaluation a permis de retenir plusieurs éléments issus de la recherche et de notions théoriques en appui à l’appréciation de la réflexion.

Published: January 2020

Les établissements universitaires québécois font face à une croissance de plus de 900 % des étudiants en situation de handicap (ESH). Cette situation impacte à la fois sur les services universitaires et les formateurs responsables des stages. Depuis les dix dernières années, des recherches contribuent à combler le manque de connaissances scientifiques à l’égard des mesures de soutien reliées aux cours. Mais très peu d’études, tous pays confondus, portent spécifiquement sur les accommodements en contexte de stage. Cet article rend compte d’une recherche exploratoire conduite en partenariat avec des formateurs universitaires et de terrain, et des coordonnateurs de stage. Trois programmes professionnels ont été étudiés afin de mettre en exergue les défis et les enjeux rencontrés par ces derniers dans l’accompagnement des ESH. La recherche s’oriente désormais vers l’expérimentation de ces mesures pour en évaluer l’impact et éclairer les ajustements requis.

Niche-ecology and isolation studies of microbes from the environment have been described as the bedrock and driving-force for bioprocess industry. This investigation was designed to determine the microbiological quality of weeds growing on aged-crude oil polluted soil. Ten (10) weeds Cyperus esculentus, Scleria pauciflora. Asystasia gangetica Harungana madagascariensis, Ancistoclaudus tectorius, Kyllinga erecta, Cinna arundinacea, Brassica chinensis, Cyperus difformis, Kyllinga bulbosa and Brachiaria mutica and their rhizospheric soil were obtained from Bodo, Gokana LGA, Sludge farm and Botanical garden of the University of Port Harcourt, Rivers State, Nigeria. The soil was enriched in Mineral Salt Media and Bonny Light Crude Oil, prior to the spread-plating on solidified media. Result of the analysis showed pH of soil samples ranged from 5.26-7.2; Electrical conductivity was 53.4-80.31µS/cm, and phosphate 0.74-5.35 mg/kg. Levels of Vanadium in pre-impacted rhizosoil obtained from Kyllinga erecta and Cinna arundinaceae were 0.61 and 0.70 mg/kg respectively. Moisture content of soil obtained from polluted and pristine environments were 11.75% and 17.82% respectively. Permeability indices were 9.0 describing the pristine soil to have low plasticity. Total heterotrophic bacterial count was within 3.5-8.0 Log10 Cfu/g distributed among the weed rhizospheres. Cyperus esculentus rhizosphere soil was more dominated with others like Achromobacter sp, B. lichenformis, B. anthracis, B. subtilis, B. fumari, Arthrobacter sp, Pseudomonas sp, P. aeruginosa, P. fluorescens. Fungal isolates were Aspergillus terreus, Trichoderma sp, and Fusarium sp. These findings further support the rhizosphere of plants as a rich bioresource for biomining of high throughput strains for biotechnological application.

Published: January 2020

AbstractThe accelerating and thorough treatment of chronic wounds still represents a major unmet medical need owing to the complex symptoms resulting from metabolic disorder of the wound microenvironment. Although numerous strategies and bioactive hydrogels are developed, an effective and widely used method of chronic wound treatment remains a bottleneck. With the aim to accelerate chronic wound healing, many hydrogel dressings with antioxidant functions have emerged and are proven to accelerate wound healing, especially for chronic wound repair. The new strategy in chronic wound treatment brought by antioxidant hydrogels is of great significance to human health. Here, the application of antioxidant hydrogels in the repair of chronic wounds is discussed systematically, aiming to provide an important theoretical reference for the further breakthrough of chronic wound healing.

AbstractThe ever‐increasing demand for clean sustainable energy has driven tremendous worldwide investment in the design and exploration of new active materials for energy conversion and energy‐storage devices. Tailoring the surfaces of and interfaces between different materials is one of the surest and best studied paths to enable high‐energy‐density batteries and high‐efficiency solar cells. Metal‐halide perovskite solar cells (PSCs) are one of the most promising photovoltaic materials due to their unprecedented development, with their record power conversion efficiency (PCE) rocketing beyond 25% in less than 10 years. Such progress is achieved largely through the control of crystallinity and surface/interface defects. Rechargeable batteries (RBs) reversibly convert electrical and chemical potential energy through redox reactions at the interfaces between the electrodes and electrolyte. The (electro)chemical and optoelectronic compatibility between active components are essential design considerations to optimize power conversion and energy storage performance. A focused discussion and critical analysis on the formation and functions of the interfaces and interphases of the active materials in these devices is provided, and prospective strategies used to overcome current challenges are described. These strategies revolve around manipulating the chemical compositions, defects, stability, and passivation of the various interfaces of RBs and PSCs.

Published: January 2020

AbstractA hybrid nanostructure composing of β‐Sn nanoparticles and reduced graphene oxide (RGO) nanosheets is successfully prepared through an effective and low‐cost solvothermal method. Both optical absorption measurements and finite element simulations confirm that the dominating plasmonic resonance frequency of such hybrid nanostructure is tunable in ultraviolet region and the near‐field enhancement effect can be achieved under broadband excitations ranging from ultraviolet to visible, which can be attributed to the coupling between β‐Sn and RGO. In addition, surface enhanced Raman scattering (SERS) determinations and corresponding calculations confirm that such all‐IV hybrid nanostructure can serve as an SERS platform and can be an alternative candidate for other plasmonic applications.
Edge Chemistry of Armchair Graphene Nanoribbons Containing Sulfur Functional Groups: Towards an Understanding of the Spin‐Dependent Electrochemistry

Published: January 2020

AbstractNumerous sulfur functional groups (35) attached to the edges of armchair graphene nanoribbons are investigated through the use of quantum mechanical calculations. Results for the band structure, formation energy, charge transfer, total hydrophilicity index, and electronic bandgaps are shown. The thiophene‐like functional group proved to be the most energetically stable, followed by the pyrrolic‐N‐sulfide. Typically, the sulfurized functional groups pulled out electrons from the ribbon, promoting p‐type doping. Ferromagnetic semiconducting behavior is found in thioketone, pyrrolic‐N‐sulfide, thiopyran‐like dioxide, and N‐thionyl aniline functional groups. Results for the valence band maximum and conduction band minimum energies demonstrate that thiopyran‐like dioxide is energetically favorable to remove spin‐down electrons, whereas thioketone is energetically favorable to catch spin‐down electrons. This fact gives insight into future spin‐dependent electrochemistry studies on functionalized graphite materials. Results for lithium adsorption demonstrate that the donated charge by lithium and interatomic distance between Li and the functional groups are strongly dependent on the nature of the functional group.

Abstract

The large island of New Guinea has a rich indigenous astacofauna represented by numerous parastacids from the genus Cherax. The western half of the island is part of Indonesian territory.
Indonesia is known to be the main exporter of ornamental crayfish globally, and certain New Guinean species are exploited as ornamentals within the international pet trade. Moreover, one non‐indigenous species has been previously recorded being cultured in Java, Indonesia. This species, the North American Procambarus clarkii, is a vector of crayfish plague, the disease that is lethal to most parastacids. This population has already tested positive for the disease.
As the transport of non‐indigenous crayfish within the Indonesian territory is not restricted, their introduction to New Guinea can be expected. The Indonesian market was therefore surveyed for ornamental crayfish and their environmental suitability evaluated, as represented by temperature during the drought and rainy seasons in New Guinea.
Four North American and one Australian species were found advertised for sale. One of them, P. clarkii, was assessed as the most damaging species, followed by other North American species. A total ban on the culture and transport of the highest risk crayfish species in Indonesia and Papua New Guinea is recommended.
Innovative und moderne Planungsmethoden im Brückenbau

Published: January 2020

AbstractBuilding Information Modeling (BIM) bietet sowohl während des Planens und Bauens als auch während des Betreibens eines Bauwerks die Chance, moderne Großprojekte termin‐ und kostengerecht zu realisieren. Denn über den gesamten Prozess können konsistente Daten die Effizienz und Qualität eines Bauwerks steigern.Hier stellt insbesondere der Brückenbau eine besondere Herausforderung dar, da trotz wiederkehrender Typologie die Abhängigkeiten der einzelnen Bauteile zur Trassierung jedes Bauwerk individuell werden lassen. Diesem Problem wird mit der Parametrisierung der Bauwerksmodelle Einhalt geboten. Konkret heißt das, dass jedes Bauteil mind. eine Abhängigkeit zur Trassierung der über‐ oder unterführten Straße/Bahn anhand der Raumkurve erhält. Verändert sich die Trassierung, so passt sich auch das Bauwerk an. Diese dauerhafte Verbindung ermöglicht es auch, dass Mengen, Bauteillisten und 2‐D‐Pläne automatisch angepasst werden. Auch Abhängigkeiten der Bauteile untereinander oder zum Geländemodell sind möglich. Somit können bereits während der Planung bauwerksinterne Kollisionen vermieden werden.Intelligente Datenmodelle können dazu beitragen, die Qualität, Effizienz und Produktivität bei der Realisierung von Bauten projektspezifisch zu steigern.Sowohl bei der Qualitätsprüfung/‐sicherung als auch der forcierten Produktivitätssteigerung ergeben sich durch den modellbasierten Ansatz neue Möglichkeiten. So lassen sich Modelle automatisiert und regelbasiert nach verschiedenen Gesichtspunkten auswerten. Während Planungs‐, aber auch Modellierungsqualität heute oft subjektiv bewertet wird, können mithilfe von Modellen Qualitätsmerkmale erhoben werden, die eine objektivere Bewertung zulassen.Nachdem Modelle und damit einhergehend Planungen heute mehr oder weniger manuell erstellt werden, teilautomatisiert ausgewertet und bewertet werden können, muss die Technologie im nächsten Schritt dazu genutzt werden, regelbasierte Mechanismen und Prozesse zu entwickeln, um ganze Planungen (teil‐)automatisiert zu erstellen. Hierzu stehen Technologien wie Knowledge Based Engineering und Machine Learning zur Verfügung, die in der Wissenschaft derzeit vertieft untersucht werden. Es gilt zu klären, wie diese Methoden in den Planungsalltag Einzug halten können.
Does betrayal aversion really guide trust decisions towards strangers?

Published: January 2020

AbstractTrust is a double‐edged sword. When warranted, it leads to positive and rewarding interactions. When not, it leads to disappointment and anger. Therefore, it has been argued that people will display “betrayal aversion” in trust situations (i.e., avoid trusting to avoid betrayal). Yet, people also feel tense and uneasy when they signal distrust to another person and thus show signs of “principled trustfulness” (i.e., choosing to trust others although being skeptical of their trustworthiness). These two theoretical orientations imply directly opposite influences on trust behavior. Thus, we conducted two laboratory studies (with a total of 841 participants) with binary trust games (implying a risk of being betrayed) and extended lottery games (implying no such risk). In both studies, we varied the payoff structures of both games. Further, we made sure that the average perceived likelihood of winning or losing money when choosing the risky option was identical in both games, as was the distribution of these likelihoods. Neither study showed any sign of betrayal aversion. Rather, participants were more willing to risk their money in the trust game than they were to invest their money in a lottery, supporting the principled trustfulness view. We discuss possible explanations why, unlike previous studies, we did not find any indication of betrayal aversion.
Hydroconversion of 5‐Hydroxymethylfurfural to 2,5‐Dimethylfuran and 2,5‐Dimethyltetrahydrofuran over Non‐promoted Ni/SBA‐15

AbstractThe selective hydroconversion of 5‐hydroxymethylfurfural (HMF) to biofuels is currently highly sought‐for. While the literature has demonstrated that this reaction is possible on promoted Ni catalysts, we show here that a monometallic, non‐promoted Ni/SBA‐15 catalyst, prepared by incipient wetness impregnation, can convert HMF to 2,5‐dimethylfuran (DMF) and to 2,5‐dimethyltetrahydrofuran (DMTHF) at 180 °C, in a consecutive way. Through a control over reaction time, high yields to DMF (71 %, at conversion of 93 %) or DMTHF (97 %, at conversion of 100 %) can be achieved. Kinetic modelling suggests a preferential route to DMF via 5‐methylfurfural (MFFR) as intermediate, though the route via 2,5‐bis(hydroxylmethyl)furan (BHMF) is also present. The favored route in the experimental conditions involves the hydrogenolysis of the hydroxyl group of HMF as first step, followed by the hydrogenation of the aldehyde function, to methylfurfuryl alcohol (MFOL). It is suggested a higher reaction rate of hydrogenation or hydrogenolysis of the side group is linked to the presence of a methyl group in the molecule. No hydrogenation of the furan ring is detected on the intermediates.
