In order to favor electronic conductivity in sodium iron fluorophosphate electrodes for lithium- or sodium-ion batteries, composites of Na2FePO4F with multi-walled carbon nanotubes (CNTs) were prepared by pilot-scale spray drying. Addition of multi-walled CNTs in the solution results in an excellent dispersion of the CNTs within the volume of Na2FePO4F and not only at the surface of the particles. Following a heat treatment at 600°C in argon in order to reach crystallization, X-ray diffraction and ex situ Mössbauer spectroscopy revealed the presence of significant amounts of Fe(III) and maghemite (γ-Fe2O3) in the powder. However, Na2FePO4F/CNTs composites exhibit good electrochemical performance when cycling against lithium, with a discharge capacity of 104mAhg-1 at C/10 rate and 90mAhg-1 at 1C rate. Therefore, operando 57Fe transmission Mössbauer spectroscopy analyses were carried out in order to investigate the evolution of the iron oxidation state during cycling. During the first discharge, all the Fe(III) is reduced to Fe(II), explaining the good electrochemical performance. [less ▲]

Le législateur, lors de l’instauration du système des sanctions administratives communales, a entendu combattre les incivilités. Cette notiond’«incivilité» vise des comportements dans l’espace public qui s’écartent de ce qui est convenable dans la vie en société. En veillant à définir les «incivilités» comme les formes les plus légères de trouble de l’ordre public, de la sécurité, de la santé et de la propreté, qui sont dégradants ou incommodants et qui dépassent les contraintes normales de la vie sociale, le législateur a satisfait aux exigences du principe de légalité.Le droit à une bonne administration de la justice tel qu’il est garanti par l’article 6 de la Convention européenne des droits de l’homme, n’exclut pas qu’une sanction administrative soit infligée par un fonctionnaire, à condition qu’un juge indépendant et impartial puisse exercer un contrôle de pleine juridic-tion sur cette décision administrative.

Recent research has shown that many prospective thoughts are organised in networks of related events, but the relational dimensions that contribute to the formation of such networks are not fully understood. Here, we investigated the organisational role of emotion by using cues of different valence for eliciting event networks. We found that manipulating the emotional valence of cues influenced the characteristics of events within networks, and that members of a network were more similar to each other on affective components than they were to members of other networks. Furthermore, a substantial proportion of events within networks were part of thematic clusters and cluster membership significantly modulated the impact of represented events on current well-being, in part through an intensification of the emotion felt when thinking about these events. These findings demonstrate that emotion contributes to the organisation of future thoughts in networks that can affect people’s well-being. [less ▲]

In order to increase the production of power on small satellites, solar panels are commonly deployed and, in some cases, reflectors are added to improve the concentration factor on solar cells. In this work, reflectors are deployed by the means of compliant mechanisms known as tape springs. Their attractive characteristics are, among others, their passive behaviour, their self-locking capacity, their elastic deformations and their robustness. However, their mechanical behaviour is highly nonlinear and requires thorough analyses in order to develop predictive numerical models. It is shown here through parametric studies that the nonlinear behaviour of a tape spring is mainly governed by its geometry. Thus, for each specific application, its dimensions can be determined in order to minimise two critical features: the maximum stress affecting the structure and the maximum motion amplitude during deployment. In this paper, an optimisation procedure is proposed to meet these requirements. [less ▲]

Deliverable 11 and 12 have been merged in the present document which can be seen as the main outcome of the activities conducted with Work Package 9 of the Robustimpact project. Section 2 presents first the sophisticated numerical investigations conducted on a reference structure subjected to impacts of vehicles. Then, Section 3 presents in details the simplified analytical models/tools developed within the present project to predict the response of a structure (or a part of a structure) further to the impact of a vehicle. With the presented models, it is demonstrated that an accurate prediction of the structural results may be obtained and that all the parameters influencing this response are mastered. Section 4 introduces the different parametric studies which have been conducted (partly using the models/tools presented in Section 3) on 2D and 3D steel and composite structures or on composite floors. Finally, Section 5 highlights the structural requirements which can be proposed as an outcome of the performed investigations. Through this document, it is demonstrated that the different objectives of Work Package 9 have been reached in the framework of this project. [less ▲]

The output of country's livestock sector is relatively high compared to other countries in the region and is estimated at 4.6 million tons of meat per year. The main constraint in the sector is the high feed price due to the dependence on imported raw materials (estimated at 65-70%). The total value of imported raw materials for animal feed production in 2013 was estimated at $ 4.1 billion. Worldwide, by-products from alcohol industry has been studied and processed into main raw materials (DDG and DDGS) for animal feed production. Meanwhile in our country, these by-products are used in its raw form in livestock feeding or used for other purposes with low economic benefit. The objective of this study was to evaluate the potential uses of the by-products from alcohol industry to produce animal feed and increase the added value for these products. The main methods used in this study were Value Chain Analysis (VCA) and SWOT analysis. Results of the study showed the different value chains of the alcohol industry as well as opportunities for the use of by-products for the production of animal feed. The results also indicate the difficulties and challenges of these application. [less ▲]

At the Institute for Steel Structures crash tests on columns were carried out to investigate the dynamic response of the member during the impact as well as the dynamic interaction of the member with the surrounding structure. The tests' campaign planned by the Università degli Studi di Trento comprises of: - two full-scale tests on 3D specimens representative of the reference buildings; From two reference structures selected as cases study two representative substructures characterised by the same overall dimensions but by a symmetric and an asymmetric configuration (i.e., column layout), respectively, have been identified. The substructures, built in laboratory, are tested reproducing the collapse of a central column. The aim of the tests is to investigate the influence of the biaxial membrane effect associated with the concrete slab in a framed structure when the collapse of a column happens. - 20 tensile tests on T-stubs related to the beam-to-column joint adopted in the reference structures and in the full-scale specimens. T-stubs associated to both the column (10 specimens) and the end-plate (10 specimens) are tested. The tests are performed at two different loading speeds aiming at investigating the influence of strain rate effects on the joint performance, with particular reference to the deformation capacity. As a reference, also quasi-static tests are planned. At the Institute of Structural Design experimental tests were carried out investigating the behaviour of 2D-frames under a column loss. In addition the behaviour of composite joints under high speed loading was examined. Within the framework of the project, two tests on composite frames were tested as well as four tests on composite joints. The 2D substructure tests planned at USTUTT have the objective to evaluate the benefit of the concrete slab compared to the behaviour of the composite frame structure concerning the development of a membrane effect. For this purpose, the results of the composite frame tests will be compared to the 3D substructure tests performed at UTRE. Therefore, the test specimens of the 2D substructure tests are adapted to the 3D substructure tests. In order to compare also the results of the composite joint tests to the behaviour of the frames and to observe the influence of the joints on each other the test specimens for the joint tests are also adapted to the frame tests. Experimental impact tests were planned at the University of Liege (ULg): 22 tests on beam-to-column joints with 5 different joint configurations and 22 tests on column base joints with 4 different joint configurations. One of the objectives of the performed study was to propose realistic joints and column bases which could fit with the laboratory facilities of ULg, what induced a downscaling of the dimension of the members in comparison to the dimension of the ones met in the reference building. With the designed specimens, it is possible to investigate the response of different joint components under impact loading, for different levels of energy (small, medium and high levels), and to compare this response to the one obtained through a static test to highlight the dynamic effects. These static tests are performed for each type of specimens and will be used to clearly determine the different level of energy to be used for the impact tests. The general test setup for all tests was derived in Work Package 3 and can be found in the deliverable D.4.1 [18] of the project. [less ▲]

Osteochondrosis dissecans (OCD) is a developmental orthopedic disease caused by a failure of the endochondral ossification in epiphyseal plates and joint cartilage. This trouble may induce the presence of osteochondral fragments in the articulation, fissures or subchondral bone cysts in the growth cartilage. Occurrence of osteochondrosis is influenced by a complex interaction of different factors. Among these, the effect of the housing and the feeding of the foals during their first months of life, have been described as risk factors for the development of osteochondrosis. The aim of this study was to investigate the evolution of OCD lesions with a longitudinal study in 204 young foals from 6 to 18 months in comparison to the type of feeding and the type of housing conditions. These factors and OCD status were obtained by a questionnaire and radiological examination, respectively. This allowed dividing the foals into four groups according to the initial OCD status and the evolution of the condition. As a result, we found that foals fed with concentrates show a higher probability to develop OCD lesions (p = 0.06), while foals not receiving concentrates, had a higher probability to heal from existing OCD lesions (p = 0.001). This study supports the theory that management factors such as feeding or housing may influence the evolution of the osteochondrosis disease. [less ▲]

Virus-like particles of human papillomavirus (HPV-VLP), resulting from the self-assembly of the capsid proteins (L1 or L1 and L2), have been widely used to study HPV as they are similar to the native virion. Moreover, two prophylactic vaccines, Gardasil® and Cervarix®, are based on HPV-VLP L1. Analytical techniques currently used to characterize HPV-VLP, such as SDS-PAGE, Western blot, ELISA, are time-consuming and semi-quantitative. In this study, capillary electrophoresis (CE) was evaluated for the analysis of intact HPV16-VLP. The usefulness of capillary inner wall coating as well as various BGEs, pH and detergent additives were investigated. Reproducible HPV-VLP analysis in CE was achieved using poly(ethylene oxide) coated capillary and a BGE containing high salt concentration and low SDS concentration. The developed method enables HPV-VLP detection in less than 10 min (migration times RSD : 1.6 %). The identity of HPV-VLP peak was confirmed by comparison with a sample obtained from a wild-type baculovirus and with VLP-based vaccine, Gardasil®, after adjuvant dissolution. Finally, we applied the developed methodology to VLP-based vaccines, demonstrating that CE could be successfully used for vaccine quality control. [less ▲]
