Abstract—This paper reports an acceleration sensing method based on two weakly coupled resonators (WCRs) using the phenomenon of mode localization. When acceleration acts on the proof masses, differential electrostatic stiffness perturbations will be applied to the WCRs, leading to mode localization, and thus, mode shape changes. Therefore, acceleration can be sensed by measuring the amplitude ratio shift. The proposed mode localization with the differential perturbation method leads to a sensitivity enhancement of a factor of 2 than the common single perturbation method. The theoretical model of the sensitivity, bandwidth, and linearity of the accelerometer is established and verified. The measured relative shift in amplitude ratio (∼312162 ppm/g) is 302 times higher than the shift in resonance frequency (∼1035 ppm/g) within the measurement range of ±1g. The measured resolution based on the amplitude ratio is 0.619 mg and the nonlinearity is ∼3.5% in the open-loop measurement operation. [less ▲]

The change in the mass, achieved with focused ion beam(FIB) milling, of one of a pair of electrostatically-coupled microelectromechanical systems (MEMS) resonators has been detected utilising the mode-localisation effect. It has been demonstrated that the shift in the amplitude ratio of the coupled-resonators at the in-phase mode frequency, in response to a mass change, is five orders of magnitude greater than the equivalent resonant frequency shift of a single resonator device. The device has been fabricated using a silicon-on-insulator (SOI) based process, which allows for high-yield and stiction-free fabrication. In addition, the design of the resonators has been created to have a larger surface area than previously reported designs, in order to facilitate future biological functionalisation. The mass sensitivity has been compared to current state-of-the-art mode-localised mass sensors and a 5.4 times increase in the amplitude ratio response to a given mass change has been demonstrated for the device in this work.

Selenium (Se) is an essential element that can be harmful for wildlife. However, its toxicity in poikilothermic amniotes, including turtles, remains poorly investigated. The present study aims at identifying selenium toxicokinetics and toxicity in juvenile slider turtles (age: 7 months), Trachemys scripta, dietary exposed to selenium, as selenomethionine SeMet, for eight weeks. Non-destructive tissues (i.e. carapace, scutes, skin and blood) were further tested for their suitability to predict selenium levels in target tissues (i.e. kidney, liver and muscle) From conservation perspective. 130 juvenile yellow-bellied slider turtles were assigned in three groups of 42 individuals each (i.e. control, SeMet1 and SeMet2). These groups were subjected to a feeding trial including an eight-week supplementation period SP8 and a following four-week elimination period EP4. During the SP8, turtles fed on diet containing 1.1 ± 0.04, 22.1 ± 1.0 and 45.0 ± 2.0 µg.g-1 of selenium (control, SeMet1 and SeMet2, respectively). During the EP4, turtles fed on non-supplemented diet. At different time during the trial, six individuals per group were sacrificed and tissues collected (i.e. carapace, scutes, skin, blood, liver, kidney, muscle) for analyses. During the SP8 (Figure 1), both SeMet1 and SeMet2 turtles efficiently accumulated selenium from a SeMet dietary source. The more selenium was concentrated in the food, the more it was in the turtle body but the less it was removed from their tissues. Moreover, SeMet was found to be the more abundant selenium species in turtles’ tissues. Body condition (i.e. growth in mass and size, feeding behaviour and activity) and survival of the SeMet1 and SeMet2 turtles seemed to be unaffected by the selenium exposure. There were clear evidences that reptilian species are differently affected by and sensitive to selenium exposure but the lack of any adverse effects was quite unexpected. [less ▲]

PIB ATPases are metal cation pumps that transport metals across membranes. These proteins possess N- and C-terminal cytoplasmic extensions that contain Cys- and His-rich high affinity metal binding domains, which may be involved in metal sensing, metal ion selectivity and/or in regulation of the pump activity. The PIB ATPase HMA4 (Heavy Metal ATPase 4) plays a central role in metal homeostasis in Arabidopsis thaliana and has a key function in zinc and cadmium hypertolerance and hyperaccumulation in the extremophile plant species Arabidopsis halleri. <br />Here, we examined the function and structure of the N-terminal cytoplasmic metal-binding domain of HMA4. We mutagenized a conserved CCTSE metal-binding motif in the domain and assessed the impact of the mutations on protein function and localization in planta, on metal-binding properties in vitro and on protein structure by Nuclear Magnetic Resonance spectroscopy. <br />The two Cys residues of the motif are essential for the function, but not for localization, of HMA4 in planta, whereas the Glu residue is important but not essential. These residues also determine zinc coordination and affinity. Zinc binding to the N-terminal domain is thus crucial for HMA4 protein function, whereas it is not required to maintain the protein structure. <br />Altogether, combining in vivo and in vitro approaches in our study provides insights towards the molecular understanding of metal transport and specificity of metal P-type ATPases.

La numérisation des données géographiques est une de ces techniques récentes qui transforment à la fois la structure politico-administrative et la construction des politiques elles-mêmes en transformant le réseau d’action publique. Ces données peuvent être utilisées dans la plupart des politiques, pourvu que les questions de distribution territoriales y soient pertinentes : on parle en ce sens d’une « géomatisation » de l’action publique. Le cadre européen avec la directive INSPIRE a donné l’impulsion et définit le cadre de référence pour une refonte des processus de production et de diffusion des données géographiques numériques. Les états doivent chacun établir une infrastructure de données géographiques numériques pour assurer l’interopérabilité entre bases de données et faciliter la diffusion, la disponibilité, l'utilisation et la réutilisation de l’information géographique au niveau de leur territoire et en Europe. En Belgique, ce sont les régions - et le niveau fédéral pour ses compétences - qui ont hérité de cette responsabilité : leurs données doivent être mises à disposition des utilisateurs, qu’ils soient décideurs ou citoyens dans des formats harmonisés afin d'en faciliter l'utilisation par tous et il faut aussi définir les principes d’échange, de tarification et les conditions d’utilisation propres à faciliter l’accès aux données et aux services en ligne. Les données géographiques numérisées ont ceci de particulier qu’elles sont produites de façon décentralisées par des acteurs publics mais aussi privés, lesquels cherchent à peser sur les choix stratégiques des autorités régionales. Au niveau de la Région wallonne a été mis en place récemment un ensemble de structure de coopération avec les usagers, les entreprises, et les autorités locales. L’administration a créé en son sein des groupes de travail transversaux pour améliorer l’intégration entre les approches thématiques contrôlées par les différentes directions. Le projet d’article trouve son origine dans l’accompagnement assuré par le SPIRAL au Département de la géomatique de la Région wallonne dans le cadre de la rédaction du plan stratégique et du plan opérationnel de la géomatique wallonne (2013-2015). L’article prendra appui sur les principes de la sociologie de la traduction (Callon, 1986) pour proposer une analyse des lieux et des processus qui contribuent à mettre en place une « gouvernance en réseau » mobilisant une logique d’innovation publique (Sørensen et al. 2011), sans suspendre pour autant les formes de coordination hiérarchiques et contractuelles.

Background: Mosquitoes are transmitters of several human diseases including, malaria, filariasis, West Nile virus and Rift Valley fever virus. To planified and succeful any mosquito vector control, a good understanding of the occurrence of specific important vector species, their abundance and distribution are needed. Objectives: The present study aimed to identify the mosquito potential vectors distributed throughout Tonga Lake region, a part of National Park of El-Kala situated in northeastern Algeria and to discuss the epidemiological importance of these insects. Results: Thirteen species representing five genera were identified: Ae. brelandi, Ae. vexans, An. plumbeus, An. labranchiae, Cx. pipiens s. l., Cx. perexiguus, Cx. theileri, Cx. pusillus, Cx. modestus, Cx. impudicus, Cs. longiareolata, Cs. annulata, Ur. unguiculata. The dominant species was Cx. pipiens s. l. with more than 70%. Conclusion: The occurrence of Aedes, Anopheles and Culex is suggestive of the presence of a risk for vector-borne diseases such as malaria, West Nile fever, Rift Valley Fever and filariasis in the area. In this study, results on species diversity may help in the future planning of vector control measures. [less ▲]

The European Commission’s White Paper on transport seeks to achieve an efficient and sustainable balance between the various transport modes. In this context, BRAIN-TRAINS is a project supported by Belgian Federal Government that deals with rail freight intermodality, approaching the problem from an interdisciplinary perspective. BRAIN-TRAINS will be able to answer the transition involved in transportation in Belgium. To analyse the sustainability impact of rail freight intermodality in Belgium, the life cycle assessment methodology will be used. The rail freight system is divided in this paper into rail operation, rail equipment and rail infrastructure. This paper shows the methodology to calculate the transport emissions related with the energy consumption during the rail operation. [less ▲]
