Cabbage (Brassica oleracea L.) is a common vegetable whose production is severely limited by insect pest pressure in Western Africa. This study was conducted during the dry and rainy season in the south Benin to evaluate the potential of tropical basil (Ocimum gratissimum L.) for repelling cabbage pests (Hellula undalis Fabricius, Plutella xylostella L. and Spodoptera litto-ralis Boisduval). In a complete randomized block design with four replicates, the insect infestation were compared between three association modalities: (i) cabbage intercropped with tropical basil, (ii) cabbage plots surrounded by tropical basil and (iii) control (no basil in the cabbage area). The presence of tropical basil near cabbage plots significantly reduced insect pest abundance on cabbage. Damages were also less important on cabbage intercropped with tropical basil. Among both intercropping modalities, alternate rows showed the best results in terms of reducing pest populations and damages than compared to cabbage plots surrounded by tropical basil. [less ▲]

Edible insects are systematically targeted as a major future food for European consumers but success in introducing entomophagy in Western society depends on factors governing consumers’ attitudes towards insect-based products. Effectively, as for sushi in the 2000s, edible insects are considered as new food products in Europe and are deeply related to a fear or a reject feeling by consumers called “food neophobia“. Consequently, several studies have been achieved to face the actual aversion of European consumers for insects. These studies principally tried to understand the insect-related neophobia, to highlight positive arguments for entomophagy development and also to test possible ways of integration of insects as food. The purpose of this chapter is to get an overview of the actual literature on edible insect acceptability in Europe to propose conceivable solutions for product development and new approaches for further studies.

Cet article examine la place du comic strip au sein du roman graphique contemporain à travers l'analyse de Little Tommy Lost (2013) de l'auteur américain Cole Closser. La particularité de cette œuvre tient en ce qu'elle se propose comme un pastiche rigoureux de divers comic strips des années 1920 et 1930, allant jusqu'à se faire passer pour une collection d'anciens strips oubliés puis redécouverts. Little Tommy Lost creuse donc une vague "rétro-réflexive" qui interroge la façon dont la bande dessinée peut remédier ses propres identités culturelles. Il s'agira de cerner les enjeux stylistiques, sériels, narratifs et culturels d'une telle remédiation rétro-réflexive. [less ▲]

Background: Identifying older people affected by cancer who are more at risk of negative health outcomes is a major issue in health initiatives focusing on medical effectiveness. In this regard, psychological risk factors such as patients’ perception of their own aging and cancer could be used as indicators to improve customization of cancer care. We hypothesize that more negative self-perception of aging (SPA) and view of cancer could be linked to worse physical and mental health outcomes in cancer patients. Methods: 101 patients diagnosed with cancer (breast, gynecological, lung or hematological) were followed for one year. They were evaluated on four occasions (baseline, 3, 6 and 12 months after the baseline). Their SPA, view of cancer and health (physical and mental) were assessed at each time of evaluation. Results: Negative SPA and/or view of cancer at baseline are associated with negative evolution of patients’ physical and mental health. Moreover, when the evolution of SPA and cancer view were taken into account, these two stigmas are still linked with the evolution of mental health. In comparison, only a negative evolution of SPA was linked to worse physical health outcomes. Conclusions: Such results indicate that SPA and view of cancer could be used as markers of vulnerability in older people with cancer. [less ▲]

A coupled Electro-Thermo-Mechanical Discontinuous Galerkin (DG) method is developed considering the non-linear interactions of electrical, thermal, and mechanical fields. In order to develop a stable discontinuous Galerkin formulation the governing equations are expressed in terms of energetically conjugated fields gradients and fluxes. Moreover, the DG method is formulated in finite deformations and finite fields variations. The multi-physics DG formulation is shown to satisfy the consistency condition, and the uniqueness and optimal convergence rate properties are derived under the assumption of small deformation. First the numerical properties are verified on a simple numerical example, and then the framework is applied to simulate the response of smart composite materials in which the shape memory effect of the matrix is triggered by the Joule effect.

This work presents a biased random-key genetic algorithm (BRKGA) to solve the electric distribution network reconfiguration problem (DNR). The DNR is one of the most studied combinatorial optimization problems in power system analysis. Given a set of switches of an electric network that can be opened or closed, the objective is to select the best configuration of the switches to optimize a given network objective while at the same time satisfying a set of operational constraints. The good performance of BRKGAs on many combinatorial optimization problems and the fact that it has never been applied to solve DNR problems are the main motivation for this research. A BRKGA is a variant of random-key genetic algorithms, where one of the parents used for mating is biased to be of higher fitness than the other parent. Solutions are encoded by using random keys, which are represented as vectors of real numbers in the interval (0,1), thus enabling an indirect search of the solution inside a proprietary search space. The genetic operators do not need to be modified to generate only feasible solutions, which is an exclusive task of the decoder of the problem. Tests were performed on standard distribution systems used in DNR studies found in the technical literature and the performance and robustness of the BRKGA were compared with other GA implementations.

According to Pausanias' Description of Greece, the sanctuary of Despoina at Lykosoura was created before the Trojan War and was already important at the time of the foundation of Megalopolis by synoecism in the first half of the fourth century B.C. However, the absence of any mention of Despoina or Lykosoura in written sources earlier than the third century as well as the archaeological evidence invite us to challenge this alleged antiquity. This paper rather ventures the hypothesis that Despoina was a cult figure created by Megalopolis and that her sanctuary was given a pan-Arcadian flavour by the importation of cults and traditions that already existed in other cities.

Les champignons dans l’univers de Mario ; l’esthétique pixellisée de Minecraft ou d’Undertale ; le bleu azur dans Portal : autant de signes visuels qui, en tant que composantes d’un style ou d’une iconographie spécifique, signent l’identité esthétique d’une œuvre vidéoludique. Or, si les caractéristiques visuelles du jeu vidéo sont régulièrement évoquées, les réflexions qu’elles initient se limitent encore trop souvent à une évaluation des performances graphiques du jeu, voire à un commentaire sur l’appartenance ou non du médium au domaine artistique. Dans ce court article – qui marque une première étape, encore balbutiante, dans ce domaine de nos recherches –, nous souhaitons ouvrir un dialogue avec le lecteur sur le rôle de l’esthétique vidéoludique, à travers l’analyse d’une œuvre. Loin d’être anecdotique, la dimension esthétique d’un jeu joue un rôle essentiel dans la co- construction d’autres composantes du dispositif ludique, telles que la jouabilité ou la narration – le terme « esthétique » ne désignant donc pas ici le jugement de goût ou le beau, mais l’ensemble des caractéristiques formelles constituant l’identité visuelle du jeu. Inscrite au cœur de la structure des objets-jeux (du game), l’esthétique vidéoludique a également un impact tant sur l’expérience de jeu que sur la posture des joueurs (le play). Cet article se propose d’explorer ce rôle potentiel de l’esthétique à travers un cas d’étude : le jeu INSIDE (Playdead, 2015). Si notre analyse peut se déployer au sein de nombreuses œuvres vidéoludiques, l’exemple d’INSIDE se distingue par une particularité : son esthétique constitue un des piliers de la narration et d’une réflexivité qui marque profondément le gameplay du jeu – réflexivité qui a été étudiée dans un précédent article (Barnabé et Delbouille ; 2017). Plonger au cœur d’INSIDE permet donc non seulement d’illustrer la façon dont l’esthétique peut être mobilisée pour renforcer les autres dimensions du jeu, mais également la nécessité d’étudier l’esthétique propre au médium vidéoludique – au-delà de la simple qualité graphique ou du jugement de goût.

Redox-active catechols are bioinspired precursors for ortho-quinones that are characterized by higher discharge potentials than para-quinones, the latter being extensively used as organic cathode materials for lithium ion batteries (LIBs). Here, this study demonstrates that the rational molecular design of copolymers bearing catechol- and Li+ ion-conducting anionic pendants endow redox-active polymers (RAPs) with ultrarobust electrochemical energy storage features when combined to carbon nanotubes as a flexible, binder-, and metal current collector-free buckypaper electrode. The importance of the structure and functionality of the RAPs on the battery performances in LIBs is discussed. The structure-optimized RAPs can store high-capacities of 360 mA h g−1 at 5C and 320 mA h g−1 at 30C in LIBs. The high ion and electron mobilities within the buckypaper also enable to register 96 mA h g−1 (24% capacity retention) at an extreme C-rate of 600C (6 s for total discharge). Moreover, excellent cyclability is noted with a capacity retention of 98% over 3400 cycles at 30C. The high capacity, superior active-material utilization, ultralong cyclability, and excellent rate performances of RAPs-based electrode clearly rival most of the state-of-the-art Li+ ion organic cathodes, and opens up new horizons for large-scalable fabrication of electrode materials for ultrarobust Li storage.

Given the limited number of written sources about the disappearance of cults in ancient Greece, as well as the important difficulties raised by their interpretation, the study of this phenomenon is almost exclusively possible through the analysis of the information obtained from archaeological excavations. However, the identification of the abandonment of a sanctuary is often difficult, mainly because of the excavation conditions but also because of post-depositional processes that may cause a destruction of the upper stratigraphic layers. Moreover, the cult of an abandoned sanctuary can be transferred into a new sanctuary, so that the archaeological sources cannot be sufficient to attest the disappearance of a cult. [less ▲]

The paper explores the textual and visual evidence from the Hellenistic Eastern Mediterranean concerning the use of incense in the ritual practice for Hellenistic political leaders. Focus is placed on the role played by incense in the construction of the religious experience of cults for human beings, with particular attention to 1) the interaction between incense burning and other ritual actions; 2) the role of incense in articulating the relationship between old (host) and new (guest) recipients of cult in specific contexts, and 3) the role of incense in Greek and non-Greek contexts of cult for rulers.

Over the years, polymer analyses using ion mobility-mass spectrometry (IM-MS) measurements have been performed on different ion mobility spectrometry (IMS) setups. In order to be able to compare literature data taken on different IM(-MS) instruments, ion heating and ion temperature evaluations have already been explored. Nevertheless, extrapolations to other analytes are difficult and thus straightforward same-sample instrument comparisons seem to be the only reliable way to make sure that the different IM(-MS) setups do not greatly change the gas phase behavior. We used a large range of degrees of polymerization (DP) of poly(ethylene oxide) PEO homopolymers to measure IMS drift times on three different IM-MS setups: a homemade drift tube (DT), a trapped (TIMS) and a travelling wave (T-Wave) IMS setup. The drift time evolutions were followed for increasing polymer DPs (masses) and charge states and they are found to be comparable and reproducible on the three instruments. [less ▲]

Fishways are installed worldwide to facilitate accessibility to functional habitats and to increase the ecological continuity of rivers. Their evaluations are increasing, but complete studies in the field with wild individuals are still scarce. In the lower Bocq River (Belgium), a pool type fishway was installed in 2011. A combined passive‐integrated‐transponder‐tag and radio‐telemetry system was designed and installed downstream of the dam and in the fishway to analyse fine‐scale individual fish behaviour. Three fish species (brown trout, European grayling, and barbel) were captured in the river; n = 125 fish were tagged and released downstream of the fishway. Behavioural metrics were proposed and used in order to attain a comprehensive view on the efficiency of the fishway, including attraction and entrance efficiency, searching and passage delays, and overall and adjusted passage efficiency. The results indicate a major problem in terms of attraction efficiency (48.9% for the trout, 20.5% for the grayling, and 41.2% for the barbel) and time to find the entrance of the fishway (mean 65.1 hr for the trout and 538.9 r for the grayling). For fish that succeed to approach the entrance of the fishway, the passage efficiency was 86.9% for the trout, 55.5% for the grayling, and 7.1% for the barbel. The time taken to cross the structure was reasonable for the salmonids (mean < 1.5 hr for trout and grayling) but very long (21 hr) for the barbel. Our results underline the necessity of a holistic approach to evaluate fishway efficiency using precise comprehensive metrics and hydraulic characterization. [less ▲]

Throughout their lives, fish accomplish frequent movements between functional habitats that are often triggered by environmental signals. We aimed to determine if rheophilic cyprinids (barbel, Barbus barbus and chub Squalius cephalus), living in different places of the same river basin, may develop similar movement periodicities and react identically to environmental cues to carry out their spawning migration. We used the capture data of three modern fish passes that were monitored continuously during three consecutive years (2010 to 2012) in three rivers of the Meuse basin in Belgium. We captured 418 individuals at adult stage, and the capture number per species was greater (80%) in spring (during the spawning migration period). The spawning migration of the barbel occurred earlier (median = 122nd day of the year) and at lower temperatures (median = 14.5°C) in the lowland rivers compared to the upland river (140th day of the year and 18.4°C). For the barbel, migration initiation differed depending on the river but finished under similar environmental conditions. In contrast, for the chub, no significant difference between rivers was observed regarding spawning migration periodicity and environmental cues. Within the same river basin, rheophilic cyprinids demonstrate flexibility in their responses to environmental variables and may optimise the start date of migration to spawning grounds depending on their local environment and individual experiences. This phenomenon was more pronounced in the barbel, which has more specific ecological requirements. [less ▲]
