District heating networks (DHN) are generally considered as a convenient, economic and environmental-friendly way to supply heat to a large amount of buildings. Some modelling methods are required to consider the dynamic behaviour of district heating networks to design them correctly, spare the investment costs and limit the heat losses related to the use of a too high operating temperatures. For the same reasons, the DHN control or retrofit of installations also requires the assessment of the DHN dynamic behaviour. To achieve this, the heat transport in DHN, which is one of the key issues in the behaviour of a whole centralized heating system, has to be correctly modelled. Previous work evidenced current limitations of one dimensional finite volume method to model heat transport in pipes and proposed an alternative method considering the thermal losses and the inertia of the pipes. The present contribution intends to experimentally validate this model on a test rig available at the Thermodynamics laboratory of the University of Liège (ULg, Belgium) and on an existing district heating network. For both experimental facilities, the current model shows good agreement between the experimental data and the simulation results for a large range of water velocities. Moreover, it is shown that the thermal inertia of the pipe has a significant influence on the outlet pipe temperature profile. [less ▲]

In order to understand the dynamic of the (sub)urbanisation and so, to quantify the anthropogenic effects of the rapid growth of tropical cities, it is crucial to find and apply valuable methods. In this contribution, the transferability of the Rüdisser et al. (2012) «Distance to Nature» hemeroby assessment method to the landscape surrounding the city of Lubumbashi (DRC) is evaluated. That methodology has the advantage of taking structural connectivity into account by computing the distance to natural habitats. As it had never been applied to an African city before, some adjustments (fitting of the local land uses types into the hemeroby levels designed to Austria) and amendments (suppression of the final classification into hemeroby level simplification) are proposed. Moreover, an analysis of the decanal (2002-2013) hemeroby dynamics is presented. Results suggest that the Distance to Nature methodology is transferable but requires good field knowledge to define reference habitats and identify them in the Landsat classified images. There was a dramatic decrease of the «natural» and «near-natural» levels in the study extent during the studied period. In addition, 32% of the land underwent anthropisation increase, mostly around cities and following a ribbon development. [less ▲]

Despite the common conception of the dorsal premotor cortex (PMd) as a single brain region, its diverse connectivity profiles and behavioral heterogeneity argue for a differentiated organization of the PMd. A previous study revealed that the right PMd is characterized by a rostro-caudal and a ventro-dorsal distinction dividing it into five subregions: rostral, central, caudal, ventral and dorsal. The present study assessed whether a similar organization is present in the left hemisphere, by capitalizing on a multimodal data-driven approach combining connectivity-based parcellation (CBP) based on meta-analytic modeling, resting- state functional connectivity, and probabilistic diffusion tractography. The resulting PMd modules were then characterized based on multimodal functional connectivity and a quantitative analysis of associated behavioral functions. Analyzing the clusters consistent across all modalities revealed an organization of the left PMd that mirrored its right counterpart to a large degree. Again, caudal, central and rostral modules reflected a cognitive- motor gradient and a premotor eye-field was found in the ventral part of the left PMd. In addition, a distinct module linked to abstract cognitive functions was observed in the rostro- ventral left PMd across all CBP modalities, implying greater differentiation of higher cognitive functions for the left than the right PMd.

L'immense espace géographique qui va de la Terre de Feu au Sud du Texas et des côtes du Chili aux Petites Antilles fut le théâtre d'une histoire marquée par d’incessants mouvements migratoires qui débutèrent au XVIe siècle avec la colonisation. La diversité et l’ampleur de ces flux d'hommes de toutes races, de toutes provenances et de toutes croyances ont été à l'origine de phénomènes d'acculturation complexes et variés. Les musiques indigènes, européennes et africaines ont été réinterprétées, recréées pour aboutir à des formes inédites variant selon les régions ou le degré d’influence de chacune des sources. Ce vocabulaire est destiné à donner un aperçu de cette immense richesse et à éclairer le public francophone sur ces traditions musicales qui, pour certaines, se sont largement diffusées. [less ▲]

In order to differentiate from competitors in terms of customer service, warehouses accept late orders while providing delivery in a quick and timely way. This trend leads to a reduced time to pick an order. This paper introduces workload forecasting in a warehouse context, in particular a zone picking warehouse. Improved workforce planning can contribute to an effective and efficient order picking process. Most order picking publications treat demand as known in advance. As warehouses accept late orders, the assumption of a constant given demand is questioned in this paper. The objective of this study is to present time series forecasting models that perform well in a zone picking warehouse. A real-life case study demonstrates the value of applying time series forecasting models to forecast the daily number of order lines. The forecast of order lines, along with order pickers’ productivity, can be used by warehouse supervisors to determine the daily required number of order pickers, as well as the allocation of order pickers across warehouse zones. Time series are applied on an aggregated level, as well as on a disaggregated zone level. Both bottom-up and top-down approaches are evaluated in order to find the best-performing forecasting method.

Aphids are frequently engaged in mutualistic associations with endosymbionts. Symbionts are bacterial or fungal microorganisms that can be obligate or facultative to aphids. Research showed facultative (or secondary) symbionts have numerous effects on their host aphids such as resistance to heat shock, parasitoids and fungus etc., which may consequently promote a co-evolution between symbionts and hosts. However, this symbiotic relation may be affected by several factors, such as the ability of symbionts to spread from aphids to others within and across populations, and the cost of infections for hosts. Moreover, aphid-symbionts interactions may be affected by aphid living environment such as its host plant, the presence of natural enemies or the temperature. Here we firstly described the functions of nine facultative symbionts (Serratia symbiotica, Hamiltonella defensa, Regiella insecticola, Rickettsia, Rickettsiella, PAXS (pea aphid X-type symbiont), Spiroplasma, Wolbachia and Arsenophonus) studied in aphids one by one, and discussed the associations between these symbionts and aphids, plants and environment. We aim to have a better knowledge of the roles the facultative symbionts play in aphid biology, ecology and evolution, which we believe can provide new inspirations for aphid control. [less ▲]

Objectives: This paper aims to summarize the hypothesis, which originates in the field of phenomenological psychopathology, of schizophrenic hyperreflexivity, and to discuss the methodological context enabling these highly subjective manifestations to emerge. Starting from the seminal hypothesis developed by contemporary psychopathology, that the schizophrenic patients appear to experience a consciousness that finds itself being forced to question phenomena which should be intuitively self-evident, the idea of this present paper is to complete the usual interpretation of schizophrenia as deficit by the hypothesis of an excess functioning of consciousness. Methods: First-person perspective is a qualitative approach completing third-person interpretation, traditional in the field of psychiatry – which consists in the attribution, from an external position, of clinical signs noted independently of the perception expressed by the patient. This first-person perspective focuses on the subjective experience expressed by the individual. To understand schizophrenia according to this perspective, the words of several schizophrenic patients have been collected as part of a clinical device. We used the EASE scale (Examination of Anomalous Self-Experience) with this aim in mind. This scale offers a phenomenologically oriented semi-structured exploration of a set of difficulties revealing anomalies of subjective experience, considered as troubles of self-awareness. EASE has been developed on the basis of self-descriptions by patients suffering from schizophrenic spectrum troubles. This tool allows the co-construction of a language between patient and clinician, focused on the patient’s particular experience and the unique phenomena he endures. Results: Besides the hyperreflexivity phenomena, the qualitative analysis of collected descriptions highlight two important features of schizophrenic being-in-the-world. First a problem of common sense, which addresses the issue of intersubjectivity and the opportunity, for schizophrenic patients, to share a social world. Then the existence of an intercorporeality trouble, since the schizophrenic hyperreflexivity experiences are accompanied by a loss of “common body”, body being the scene where intersubjectivity is performed. Employing EASE, and the ensuing first-person perspective, is relevant in a psychotherapeutic approach; on one hand in the process of acknowledgement of the disease (which has to be made by the patient as well as by the clinician), on the other hand in the communication with families of schizophrenic patients. Conclusions: The phenomenological interpretation offered by the application of a first-person perspective in the understanding of schizophrenic patients experience, as well as the interest showed in the hyperreflexivity phenomenon, suggest an outlook of schizophrenia which isn’t reduced to a deficit interpretation anymore (without denying the latter), and which uncovers not a weakening, but a surprising intensification of consciousness.

The Typus Melancholicus (TM) is a pre-melancholic personality structure, defined by Tellenbach and Kraus and characterized by the orderliness, conscientiousness, norm orientation and intolerance of ambiguity. This study aims to discriminate the existence of a subgroup TM, among a unipolar depressive population. In order to prove the existence of this subgroup, we translated and administrated the Criteria for Typus Melancholicus (CTM) to a sample of 20 unipolar patients and 20 control participants. The research hypothesis was to find a similar proportion to the one observed in the literature (50% of TM in the unipolar sample). The results demonstrate, as expected, that half of the unipolar sample belongs to a homogeneous subgroup that displays the TM features. Furthermore, no control subjects displays the TM features. Those results suggest that the TM features design a coherent and typical psychopathological structure that can be found in an important proportion of unipolar depressive population. Our study identifies and confirms the existence of a distinct heterogeneity (TM/noTM) inside the unipolar group. This distinction opens the door to some important perspectives in terms of therapy.
