This paper is concerned with the place and role of general practitioners in the follow-up of patients submitted to bariatric surgery in the province of Liège. The results of the analysis were compared with clinical practice guidelines published by the French Haute Autorité de Santé (HAS). Fifteen interviews were conducted with GPs who follow up operated patients. The results highlight the GPs’ wish to fully participate in the follow-up of those patients. Their medical supervision is centered on the HAS clinical practice guidelines, taking into account the intake deficiencies as well as the patient’s psychological experience. However, some aspects are disregarded, mainly because of a lack of theoretical knowledge (some biological parameters, pregnancy and contraception). The short consultation time along with the poor communication with the hospital multidisciplinary team were mentioned as obstacles to a good quality follow-up. Progress is still needed to reach the clinical practice guidelines. However, there is a wish to better collaborate. Organising coordination meetings between professionals along with an early implication of the GP – even before surgery – represent possible solutions. [less ▲]

Le projet de recherche est basé sur le concept de système de production de l'habitat. Un système de production de l'habitat vise à accroître et à améliorer l'offre en logements. Il se structure par les interactions entre les modes d'habiter (la demande), les modes de production (l'offre) et les modes de gestion (l'intervention de la puissance publique). Pour le contexte wallon, le système de production actuel est lié à un usage peu parcimonieux de la ressource foncière et à des problèmes importants d’étalement de la périurbanisation. Néanmoins, des signaux avant-coureurs de la mise en place d'un système de production plus vertueux vis-à-vis des principes stratégiques de l'aménagement du territoire semblent se manifester. La recherche I.5. intitulée « Production de l’habitat et enjeux territoriaux » ambitionne d'étudier l'ampleur de ces changements et de comprendre quels sont les processus socioéconomiques qui les instituent. Au final, son objectif est de préciser comment l’intervention de la puissance publique peut s’appuyer sur ces pratiques émergentes en vue de soutenir la transition vers un nouveau système pour la production de l’habitat wallon. Notre ambition est donc d’identifier les conditions qui conduisent à des pratiques plus vertueuses vis-à-vis des principes stratégiques de l’aménagement durable, afin de les renforcer et de les généraliser dès que possible.

Death of calves after epileptiform seizures can be caused by metabolic disorders including hypomagnesaemia, although a range of other conditions may also be implicated and therefore also warrant investigation. Hypomagnesaemia is primarily observed in herds where calves are fed exclusively with either milk or milk substitute products. Hyperparathyroidism is associated with congestion and hypertrophy of the parathyroid gland and causes both hypercalcaemia and hypophosphataemia. However, its exact aetiology currently remains unclear. The purpose of this study was to explain epileptiform seizures in calves from a cattle herd presenting both deaths and decreased average daily gain (ADG). A Montbeliard herd with calves presenting epileptiform seizures from the age of five weeks was studied. The herd consisted of 39 cows and 46 calves. Tachycardia, nervousness and trampling, violent seizures of tetany lasting approximately 15 minutes were all observed, while opisthotonos was observed in 5 calves. Three of the latter calves died. The remaining calves presented a decreased ADG. Blood and urine biochemical assays were performed on 8 sick calves to determine the aetiology of the clinical signs. The assays revealed normo/hyper-calcaemia, hypophosphataemia and hypomagnesaemia, as well as hypocalciuria, hyperphosphaturia and hypomagnesuria. Deficiencies in iodine, iron and vitamins A, D3 and E were also reported in the herd. These calves could potentially be suffering from hyperparathyroidism. Hyperparathyroidism results in hypomagnesaemia, hypovitaminosis-A and, on occassion, hypercalcaemia and hypophosphataemia. This condition can lead to seizures, muscular problems, heart attacks and anorexia. The simultaneous occurrence of hypomagnesaemia, hyperparathyroidism and hypovitaminosis-A has been never described in related research literature. This is, therefore, in all likelihood a new metabolic disorder facing young cattle. Blood and urine biochemical assays are important tools for the detection of this pathological entity in calves. A dosage of parathyroid hormone (PTH) by the enzyme-linked immunosorbent assay (EIA) method using a kit suitable for cattle can be used to detect hyperparathyroidism. [less ▲]

Carob galactomannan fine chemical structure is closely related to the physical behavior developed in aqueous solution. Three elements of structural characterization are mainly described in the literature: the degree of galactose substitution, chain length, and galactose units distribution. This review article will attempt to highlight the impact of different structural features on physical properties such as solubility, viscosity, formation of hydrogels or gels in combination with other saccharides. The impact of industrial purification process on the structure and physical properties is also developed. [less ▲]

Three dimensional (3D) open porous scaffolds are commonly used in tissue engineering (TE) applications to provide an initial template for cell attachment and subsequent cell growth and construct development. The macroscopic geometry of the scaffold is key in determining the kinetics of cell growth and thus in vitro ‘tissue’ formation. In this study we developed a computational framework based on the level set methodology to predict curvature-dependent growth of the cell/extracellular matrix domain within TE constructs. Scaffolds with various geometries (hexagonal, square, triangular) and pore sizes (500 and 1000 µm) were produced in house by additive manufacturing, seeded with human periosteum-derived cells and cultured under static conditions for 14 days. Using the projected tissue area as an output measure, the comparison between the experimental and the numerical results demonstrated a good qualitative and quantitative behavior of the framework. The model in its current form is able to provide important spatio-temporal information on final shape and speed of pore-filling of tissue engineered constructs by cells and extracellular matrix during static culture.

Indira Gandhi’s last years in office as India’s prime minister ran from January 1980 to her assassination in October 1984 but until now no book has been devoted to her final term. Among the principal themes discussed in this innovative volume are how Indian politics and society changed in the 1970s, including the state of Emergency (1975-77) Congress’s response to insurgency in Punjab, Assam and Kashmir, the rise of new forms of political mobilisation in the early 1980s and the prime minister’s relationship with the key institutions of state. Maiorano also reveals how Mrs Gandhi’s policies in the 1980s impacted on the big industrialists, the middle class, the rich peasantry and the poor, thereby crucially re-orienting India’s economic strategy. Autumn of the Matriarch is the first major study of MrsGandhi’s last years in power, an important juncture in India’s recent history, as it was then that emerged trends that influenced the country for the next three decades.

The present paper investigates the dynamics of a real-life spacecraft structure possessing a strongly nonlinear component with multiple mechanical stops. A full-scale finite element model is built for gaining additional insight into the nonlinear dynamics that was observed experimentally in a companion paper (Part I). To this end, advanced techniques and theoretical concepts such as numerical continuation and nonlinear normal modes are exploited. [less ▲]

DINEOF (Data INterpolating Empirical Orthogonal Functions) is a powerful tool based on EOF decomposition developed at the University of Liege/GHER for the reconstruction of missing data in satellite datasets, as well as for the reduction of noise and detection of outliers. DINEOF is openly available as a series of Fortran routines to be compiled by the user, and as binaries (that can be run directly without any compilation) both for Windows and Linux platforms. In order to facilitate the use of DINEOF and increase the number of interested users, we developed a web-based interface for DINEOF with the necessary parameters available to run high-quality DINEOF analysis. This includes choosing variable within selected dataset, defining a domain, time range, filtering criteria based on available variables in the dataset (e.g. quality flag, satellite zenith angle …) and defining necessary DINEOF parameters. Results, including reconstructed data and calculated EOF modes will be disseminated in NetCDF format using OpenDAP and WMS server allowing easy visualisation and analysis. First, we will include several satellite datasets of sea surface temperature and chlorophyll concentration obtained from MyOcean data centre and already remapped to the regular grid (L3C). Later, based on user’s request, we plan to extend number of datasets available for reconstruction. [less ▲]

Ensemble assimilation schemes applied in their original, global formulation have no problem in respecting linear conservation properties if the ensemble perturbations are setup accordingly. For realistic ocean systems, only a relatively small number of ensemble members can be calculated. A localization of the ensemble increment is thus necessary to filter out spurious long-range correlations. However, the conservation of the global property will be lost if the assimilation is performed locally since the conservation requires a coupling between model grid points, which is filtered out by the localization. In the ocean, the distribution of observations is highly inhomogeneous. Systematic errors of the observed parts of the ocean state can lead to spurious systematic adjustments of the non-observed part of the ocean state due to data assimilation. As a result, global properties which should be conserved, increase or decrease in long-term simulations. We propose an assimilation scheme (with stochastic or deterministic analysis steps) which is formulated globally (i.e. for the whole state vector) but where spurious long-range correlations can be filtered out. The scheme can thus be used to enforce global conservation properties and non-local observation operators. Both aspects are indeed linked since one can introduce the global conservation as a weak constraint by using a global observation operator. The conserved property becomes thus an observed value. The proposed scheme is tested with the Kuramoto-Sivashinsky model which is conservative. The benefit compared to the traditional covariance localization scheme (with an ad-hoc step enforcing conservation) where observations are assimilated sequentially is shown. The assimilation scheme is suitable to be implemented on parallel computers where the number of available computing cores is a multiple of the ensemble size. [less ▲]

The present study focused on re-cancellation behaviors in unilateral neglect (i.e., the tendency to search repeatedly items located on the right side in visual search tasks), and used a neuropsychological approach to identify the cerebral correlates of this deficit. Fourteen patients suffering from left neglect and 14 elderly age-matched controls performed a cancellation task without visual feedback. Neglect patients cancelled fewer targets than controls, and re-cancelled an abnormally high number of targets. Lesion maps were used to compare the location of brain damage in neglect patients with the highest versus the lowest percentage of re-cancellations. Anatomical data revealed that the right insula is commonly damaged in 5 out of 6 patients with the highest re-cancellation percentage, but is spared in the subgroup of patients with the lowest re-cancellation percentage. These results suggest that damage to the right insula may contribute to pathological visual search in spatial neglect, possibly by reducing interaction between the ventral and dorsal attention network (the latter being more directly involved in spatial processes).
