The radiation therapy department (RTD) initiated in 2009 a policy of open and transparent reporting of events not harming (near incidents) and potentially harming patients (incidents and accidents). This approach was immediately followed by the leader’s decision to engage towards the European Foundation for Quality Management (EFQM) excellence model. The EFQM approach structured the journey of the RTD to enterprise risk management. We intend to demonstrate in the five main fields of the EFQM approach (leadership, policy and strategy, people/personnel, partnership and resources, processes), how the journey to continuous improvement in quality and safety did evolve and was accelerated in RTD. The assessment made by external evaluators evolved from a minimum of 90 points (basic requirement for level 1 in 2009) to a at least 180 points (basic requirement for level 2 in 2011), to reach 400 points in 2013 (270 required for level 3 and 450 required for level 4).

Even though the Circular Economy paradigm clearly puts the emphasis on recycling, it is essential to understand that we will still need for decades to explore and find resources in the earth crust. Mining is vital to feed the loop and make sure enough metals and minerals are made available to society. But, mining is also one of the most challenging industrial operations when it comes to sustainability objectives. A modern education in mineral resources engineering must build on a strong technical background but give students the opportunity to confront their knowledge with societal needs and responsibilities. The EMerald Erasmus Mundus Master program in Georesources Engineering was set up by four leading European universities with the clear objective to educate responsible professionals who will be actors of sustainable solutions. Therefore, the University of Lorraine, the Lulea Technical University, the TU Bergakademie Freiberg and the University of Liege (coordinator) designed a unique curriculum bridging the traditional gap between natural sciences and engineering, encompassing the valley too often separating the industrial operators from the stakeholders of a mining project. The program offers a unique blend of courses from geology to mineral processing with the aim to familiarize students with the most advanced tools for improving the efficiency of processes. Field trips and industrial visits are a key component of this program as are the non-technical seminars delivered by professionals (lawyers, entrepreneurs, NGO leaders, etc.). Evaluation is often based on written reports, documentary research and short oral presentations to make sure students acquire the indispensable soft skills for efficient communication on environmental and societal issues linked to the impact of extractive activities. Internships and hands-on practices on pilot platforms or laboratory equipments are absolutely essential to reach the highest standards and meet the objectives of the master program. This is costly and can only be maintained thanks to the strong presence of the participating universities in research programs. All four universities are core partners of the EIT Raw Materials knowledge innovation community. This gives an additional leveraging effect when it comes to the education of young entrepreneurs with a strong sustainability mindset. [less ▲]

In order to model the nitrate concentration of the recharge water in a spatially distributed way for the agricultural areas of the Walloon Region of Belgium, the EPIC model was first adapted to the specific soil description by modifying the reservoir sizes. It was also adapted to the regional crop production by modifying classcrop files in relation with observed data (both aerial and underground crop growth, yield) in wheat, sugar beet, and potato fields. As the vadose zone presents a depth between 1.5 and 104 m in this region, new reservoirs were added according to the geological descriptions available. Deep nitrate transfer was validated in a specific site where cropping history was known. Nitrate nitrogen after harvest in the root zone was validated for wheat within different crop rotations using the first results of a nitrate-monitoring program planned by the authorities to test the effectiveness of the mitigation measures in agriculture. This extended model was also linked to a GIS (geographical information system) using 1 km2-cells. All the required data were rasterised to allow HRU (hydrological response unit) identification within the cells. The cell’s daily water flows are weighted flows of each HRU depending on their relative area within the cell. Water balances at catchment scale allow us to validate the calculation. Taking into account the evolution of distributed land use and observed climatic data, we have built maps of fast indicators and long-term indicators. The first map represents nitrate concentration in the water leaving the root zone and the second one represents the time transfer for nitrate from 1.5 m depth to the groundwater table and nitrate concentration in recharge water. These maps constitute major tools for nitrogen management at a regional level. [less ▲]

We use the continuous wavelet transform to perform a space-scale analysis of the AT and GC skews (strand asymmetries) in human genomic sequences, which have been shown to correlate with gene transcription. This study reveals the existence of a characteristic scale `c 25 ± 10 kb that separates a monofractal long-range correlated noisy regime at small scales (` ¡ `c ) from relaxational oscillatory behavior at large-scale (` ¿ `c ). We show that these large scale nonlinear oscillations enlighten an organization of the human genome into adjacent domains ( 400 kb) with preferential gene orientation. When using classical techniques from dynamical systems the- ory, we demonstrate that these relaxational oscillations display all the characteristic properties of the chaotic strange attractor behavior observed nearby homoclinic orbits of Shil'nikov type. We discuss the possibility that replication and gene regulation processes are governed by a low-dimensional dynamical system that displays deterministic chaos. c 2004 Elsevier B.V.

Some scientists who study animals have emphasized the need to focus on the “point of view” of the animals they are studying. This methodological shift has led to animals being credited with much more agency than is warranted. However, as critics suggest, on the one hand, the “perspective” of another being rests mostly upon “sympathetic projection,” and may be difficult to apply to unfamiliar beings, such as bees or even flowers. On the other hand, the very notion of agency still conveys its classic understanding as intentional, rational, and premeditated, and is still embedded in humanist and Christian conceptions of human exceptionalism. This paper seeks, in the first part, to investigate the practical link between these two notions and the problems they raise. In the second part, following the work of two historians of science who have revisited Darwin’s studies of orchids and their pollinators, it will observe a shift in the meaning of the concept of agency. Indeed, creatures may appear as “secret agents” as long as we adopt a conventional definition of agency based on subjective experience and autonomous intention. However, when reframed in the terms of “agencement”—an assemblage that produces “agentivity”— agency seems to be much more extensively shared in the living world. We will then explore some of the concrete situations in which these agencements are manifested, and through which creatures of different species become, one for another and one with another, companion-agents.

The European Union plays an ever increasing role in the institutional organisation of market supervision, by either creating new supranational supervisory bodies or by circumscribing Member States autonomy in designing national supervisory authorities. European Union law draws particularly volatile legal boundaries that create a playing field between supranational policymaking and national institutional choices. This dissertation aims to identify those legal boundaries. In doing so, it additionally seeks to analyse the role of European Union law in the determination and delineation of such boundaries as part of the EU s larger federalism project. The dissertation comprises two main parts. The first part structures the key characteristics of supranationally structured market supervision in the European Union. To that extent, the dissertation studies whether and to what extent supervisory powers are being shared betweensupranational and national actors, the institutional actors responsibleand cooperative mechanisms created by supranational law across different sectors of market regulation. The part particularly focuses on two differently structured market supervision regimes: competition law supervision and financial market supervision. The second part builds upon the key characteristics identified by structuring them into a constitutional framework of competence attribution and competence exercise engaged upon by EU institutions. In particular, this part seeks to assess to what extent the key characteristics reflect a translation of EU constitutional principles in accordance with a particular model of European federalism. Identifying that model allows to better explain and predict institutional evolutions across differently regulated market segments. [less ▲]

As Christopher Manes writes, ‘[n]ature is silent in our culture […] in the sense that the status of being a speaking subject is jealously guarded as an exclusively human prerogative’ (Manes, 1996). According to this view, nature is less silent than silenced, the difference lying in a refusal to have a relationship with the natural world because of the lack of adequate language to describe our relationship with our natural environment. Human faculties promoted by the Enlightenment have led humans to believe that our language ‘ha[s] no analogues in the natural world’. I will show that American authors such as Henry David Thoreau, John Muir, Aldo Leopold or Edward Abbey accounted for a multi-sensorial experience of nature that betrays an attempt to find a form of language that would relate humans to natural elements. Although nature does not ‘speak’, I will argue that humans were provided with their sensory perception that allows them to appreciate worldness and to develop a harmonious relationship with the rest of the world. I will also stress that our alienation from the natural world is as much a cultural problem as it is a consequence of Western consumer capitalism and supermodernity, as suggested, for example, in Don DeLillo’s White Noise (1985). Adopting an ecocritical approach, I will examine the ways in which we tend to perceive worldness as silent and how literary texts may revive worldness and world as essential concepts in the study of the relationship between literature and our physical environment.

Skin microrelief alters progressively with age. Wrinkles do not result from these changes but are superimposed upon them. Wrinkles result from structural changes in the epidermis, dermis and hypodermis. Four types of wrinkles can be recognized. Type 1 wrinkles are atrophic. Type 2 wrinkles are elastotic. Type 3 wrinkles are expressional. Type 4 wrinkles are gravitational. Each type of wrinkle is characterized by distinct microanatomical changes and each type of wrinkle develops in specific skin regions. Each is likely to respond differently to treatment. Skin microrelief and skin folds can be identified on histological examination. By contrast, only minimal dermal changes are found beneath permanent or reducible wrinkles compared with immediately adjacent skin. A series of objective and non-invasive methods is available to quantify the severity of wrinkling. [less ▲]

Deep disposal of the high-level and high-lived radioactive wastes in the potential geological formations is envisaged as a possible solution in the framework of long-term management of these wastes. The argillaceous materials, namely Boom Clay, are potential to constitute the natural barrier aimed at confining the nuclear waste and protecting the biosphere from it. Around galleries excavated at depth in these media, the creation of a damaged zone with significant irreversible deformation is generally unavoidable. A considerable change in the host rock properties could be likely resulted in this zone, which may potentially be important with respect to the long-term evolution and the performance of the system. In this context, a paramount interest addresses characterization of the so-called Excavation Damaged Zone (EDZ), predicting its extent, and development of localized fracturing during and after the underground excavation in the host rock. This constitutes the foundation of this work, focusing on the Boom Clay formation as the reference potential host rock in Belgium. Dealing with this purpose, providing a state of knowledge on the hydro-mechanical behavior of Boom Clay, and validating a set of parameters which could realistically reproduce its response through the numerical modelings are firstly addressed as the requisites. Moreover, a special focus is made on the dilatation factor of the rock, commonly described through the dilatancy angle parameter. Correct estimation of the dilatant behavior of a rock has an essential role in a realistic simulation of its volumetric behavior, fracturing threshold during the rock deformation process and its post-failure response. Therefore, a new formula is developed for consideration of the variable dilatancy angle, incorporated into an internal frictional elasto-plastic hardening/softening model, within the LAGAMINE finite element code. This development overcomes the inconveniences associated to using a constant dilatancy angle, for instance encountered in our numerical simulations of some laboratory small-scale tests as well as a large-scale excavation. This study then focuses more particularly on simulation of EDZ extension at the large scale excavation, around the Connecting gallery (in the HADES URL, Mol, Belgium), through analyzing the evolution of strain localization in shear bands mode. The modeling takes into account of the initial anisotropic stresses, mechanical cross-anisotropy, anisotropic permeabilities, and gravity effects. As a result, an eye-shape extension of EDZ accompanied by an anisotropic convergence of the rock is predicted. A coupled analysis addresses the pore water pressure distribution during the excavation period and in long-term while no more evolution of the localized shear bands is predicted. To assess the reliability of the numerical results, some available in-situ measurements and observations, within the clay, during the gallery's construction and afterwards are precisely analyzed, and then compared with the corresponding numerical predictions. As a result, a good agreement is found between the in-situ data and simulated results. Moreover, the above study is integrated with a particular analysis of the contact mechanism on the interface between the clay and the gallery's lining. Thence, the coupled interface element is introduced to deal with the contact phenomenon. The obtained results reveal some interesting features regarding the development of contact pressure on the interface linked to the evolution pattern of strain localization within the clay around the gallery. Furthermore, with regard to the own lining behavior, a development of the modeling with the aim of consideration of a discontinuous lining (made of the segments as the real case) is performed. We propose an approach to realistically reproduce the response of the lining's segments and their contact phenomena in the course of a long-term simulation. Defining the interface elements between the neighboring segments, with respect to the real installation procedure of the lining during the gallery construction, this process is aimed to be simulated through some evolution of the contact pressure on the segments' interfaces. As a result, a considerable improvement is achieved in reproducing the in-situ measurements provided in the lining. The numerical and measured evolution of strain and displacement are in a good agreement. [less ▲]
