Wild boar ability to cause important damages to agricultural lands is not anymore to be demonstrated. These damages often raise conflicts between farmers and hunters due to the associated economic losses. Objective and accurate method for real impact assessment of losses suffered by farmers is thus needed. Currently,in Wallonia damage assessment is performed from the ground by experts, asked to evaluate precisely the area impacted. This task is time and man power consuming. Moreover, damaged areas are often large and consequently, sampling is mandatory and can induce accuracy issues. Recent development of unmanned aerial vehicle (UAV / drone) toghether with lower cost and better accessibility for civil society and scientific community, makes now possible the use of this technology for wildlife researches. Through photogrammetric 3D reconstruction of the field crop, UAV can allow to objectively and precisely measure the area impacted by wild boar damages. In a context of increasing issues caused by wild boar to agriculture, and the need for stakeholders for accurate impact assessment, we tested an innovative approach to estimate more effectively the area impacted by wild boar.

This paper presents a system that gives the illusion of a 3D immersive and interactive environment with 2D projectors. The user does not need to wear glasses, nor to watch a (limited) screen. The virtual world is all around him, drawn on the floor. As the user is himself immersed in the virtual world, there is no need for a proxy like an avatar; he can move inside the virtual environment freely. Moreover, the Isee-3D system allows a user to manipulate virtual objects with his own body, making interactions with the virtual world very intuitive. Giving the illusion of 3D requires to render images insuch a way that the deformation of the image projected on thefloor is taken into account, as well as the position of the user’s “eye” in its virtual world. The resulting projection is neither perspective nor orthographic. Nevertheless, we describe how thiscan be implemented with the standard OpenGL pipeline, without any shader. Our experiments demonstrate that our system is effective in giving the illusion of 3D. Videos showing the results obtained with our I-see-3D system are available on our website http://www.ulg.ac.be/telecom/projector [less ▲]

IA-2 has been identified as an autoantigen that is recognized by immunoglobulins from insulin-dependent diabetic (IDDM) patients. Using a liquid phase radiobinding assay, we performed an IA-2-autoantibody (IA-2-Ab) assay in 474 IDDM patients and 482 non-diabetic control subjects aged 0-3 years. IA-2-Ab were detected in 58% of the patients and 0.8% of control subjects. Their prevalence in patients was lower than that of islet cell autoantibodies (ICA; 73%) or glutamic acid decarboxylase (M(r) 65 kDa)-autoantibodies (GAD65-Ab; 82%) but higher than that of insulin autoantibodies (IAA; 42%). IA-2-Ab were more frequent in patients under age 20 years (70%) than between 20 and 40 years (45%; p < 0.001). In the whole IDDM group, 92% of patients were positive for at least one of the three molecular assays, which is higher than the positivity for the ICA assay (73%). Only 1% was negative in the molecular assays and positive in the ICA assay. IA-2-Ab levels were positively correlated with ICA titres (p < 0.001) and HLA DQ A1*0301-DQ B1*0.02 (p < 0.003) by multivariate analysis. In a group of 481 non-diabetic siblings (age 0-39 years) of IDDM patients only 7 were IA-2-Ab positive (1.5%). All seven were under age 20 years and positive for at least two other autoantibodies and for DQ A1*0301-DQB1*0302. Four of these seven developed IDDM during the 6-70-month follow-up period. The positive predictive value of IA-2-Ab (57%) was higher than that of ICA, GAD65-Ab or IAA alone, or in combination (< or = 20%) but these calculations are restricted by the relatively short observation period and the small number of cases. The only IA-2-Ab-negative case of pre-diabetes was also negative for IAA and GAD65-Ab, while it was strongly positive for ICA. In conclusion, IA-2-Ab show a high diagnostic specificity for IDDM and are predictive markers of impending diabetes in siblings of patients. In combination with other molecular antibody assays they may replace ICA testing in future. Our data also indicate that other autoantibodies than IA-2-Ab, GAD65-Ab and IAA contribute to ICA.

The peroxidase and IAA-oxidase activities, the degree of auxin protection and the amount of soluble phenolics were determined in in vitro cultured shoots of a nonrooting mutant, inc, of tobacco compared to its wild homologue. The mutant and wild shoots showed similar peroxidase variations along the growth cycle of 21 days, but with higher levels of activity for the I ac mutant. During this growth cycle, the minimum of peroxidase activity occurred at day 14 for both tobacco whole shoots. However. this minimum of activity did not occur at the same day in the basal part of the stem, where roots may appear, of the two types of tobacco. Both mutant and wild whole shoots showed about the same IAA-oxidase activity in the fractions resulting from a gel filtration of the crude extracts through a sephadex G-100 column but differed in the degree of auxin protection. The rac shoots exhibited a very high level of auxin protectors of low molecular weight, among which chlorogenic acid. They were also characterized by eight to nine times higher level of soluble phenolics. The relationships between these biochemical aspects in relation to the absence of root formation in the me mutant are discussed. (C) 2000 Elsevier Science Ireland Ltd. All rights reserved. [less ▲]

Context. Asteroseismology is a powerful tool to access the internal structure of stars. Apart from the important impact of theoretical developments, progress in this field has been commonly associated with the analysis of time-resolved observations. Recently, the so-called macroturbulent broadening has been proposed as a complementary and less expensive way - in terms of observational time - to investigate pulsations in massive stars. <BR /> Aims: We assess to what extent this ubiquitous non-rotational broadening component which shapes the line profiles of O stars and B supergiants is a spectroscopic signature of pulsation modes driven by a heat mechanism. <BR /> Methods: We compute stellar main-sequence and post-main-sequence models from 3 to 70 M[SUB]⊙[/SUB] with the ATON stellar evolution code, and determine the instability domains for heat-driven modes for degrees ℓ = 1-20 using the adiabatic and non-adiabatic codes LOSC and MAD. We use the observational material compiled in the framework of the IACOB project to investigate possible correlations between the single snapshot line-broadening properties of a sample of ≈260 O and B-type stars and their location inside or outside the various predicted instability domains. <BR /> Results: We present an homogeneous prediction for the non-radial instability domains of massive stars for degree ℓ up to 20. We provide a global picture of what to expect from an observational point of view in terms of the frequency range of excited modes, and we investigate the behavior of the instabilities with respect to stellar evolution and the degree of the mode. Furthermore, our pulsational stability analysis, once compared to the empirical results, indicates that stellar oscillations originated by a heat mechanism cannot explain alone the occurrence of the large non-rotational line-broadening component commonly detected in the O star and B supergiant domain.

The Intra-Americas Sea (IAS) surface circulation is characterized by large scale currents. The Caribbean current, which originates in the Lesser Antilles, travels westwards through the Caribbean Sea and eastern Mexico and passes through the Gulf of Mexico to finally form the Gulf Stream. This complex system of currents is also characterized by a high mesoscale variability, such as eddies and meanders. The objectives of this work are twofold: first, the multi-scale surface circulation of the IAS is described using satellite altimetry. The topographic influence of the different basins forming the IAS, the characteristic time and spatial scales, and the time variability of the surface circulation will be addressed. The second objective is to analyze the influence of this large scale circulation on a small scale coastal domain with a ROMS-based model of the Cariaco basin (Venezuela). Cariaco is a deep (1400 m), semi-enclosed basin connected to the open ocean by two shallow channels (Tortuga and Centinela Channels). Its connection with the open sea, and therefore the ventilation of the basin, occurs in the surface layers. The Cariaco ROMS model will be used to study the exchanges of mass, heat and salt through the channels. A 1/60 degree ROMS model nested in the global 1/12 degree HYCOM model from the Naval Research Laboratory will be used for this study. In addition, a series of observations (satellite altimetry and in situ temperature, salinity and velocity data), will be used to assess the influence of the Caribbean circulation on the basin.

À travers l’étude des termes grecs "iatreion" et "ergastèrion", cet article a pour objectif d’élucider non seulement les dénominations, mais aussi le statut et le fonctionnement des lieux d’exercice des médecins grecs. L’enquête se fonde sur les occurrences de ces deux mots relevées dans la documentation papyrologique, épigraphique et littéraire. Malgré un corpus réduit, la confrontation des diverses sources permet de donner une image assez précise de l’organisation et du rôle joué par le "iatreion", des maux qui y étaient soignés et des traitements qui y étaient appliqués par les médecins. Quant à l’"ergastèrion", trois témoignages, un papyrus et surtout deux inscriptions découvertes à Métaponte et Magnésie du Méandre, suggèrent l’utilisation exceptionnelle de ce terme dans un contexte médical ; il semble alors désigner un centre de soins de taille plus importante, où exerçaient plusieurs médecins.

Thyrotoxicosis is the clinical syndrome that results when tissues are exposed to high levels of circulating thyroid hormones. In most instances, thyrotoxicosis is due to hyperthyroidism, a term reserved for disorders characterized by overproduction of thyroid hormones by the thyroid gland. Nevertheless, thyrotoxicosis may also result from a variety of conditions other than thyroid hyperfunction. The present report focuses on the etiologies, pathophysiology and treatment of iatrogenic thyrotoxicosis. Iatrogenic thyrotoxicosis may be caused by 1) subacute thyroiditis (a result of lymphocytic infiltration, cellular injury, trauma or radiation) with release of preformed hormones into circulation, 2) excessive ingestion of thyroid hormones ("thyrotoxicosis factitia"), 3) iodine-induced hyperthyroidism (radiological contrast agents, topical antiseptics or other medications). Among these causes of iatrogenic thyrotoxicosis, that induced by the iodine overload and cytotoxicity associated with amiodarone represents a significant challenge. Successful management of amiodarone-induced thyrotoxicosis requires close cooperation between endocrinologists and endocrine Surgeons. Surgical treatment may have a leading yet often underestimated role in view of the potential life-threatening severity of this disease, whereas others kinds of iatrogenic thyrotoxicosis are usually treated conservatively.

Ibandronate is a nitrogen-containing bisphosphonate which has been shown to reduce vertebral fracture rates, when given orally either daily or intermittently. Non-vertebral antifracture efficacy of ibandronate has been derived from a post-hoc analysis focusing on patients at high risk of developing non-vertebral fractures (low bone mineral density at the femoral neck). Once-monthly administration of oral ibandronate has been linked to significantly greater increases in bone mineral density, at the spine, hip and femoral neck, compared to daily formulation. This monthly formulation has a safety profile similar to the one observed with the daily administration of the compound. Adherence to monthly bisphosphonates appears to be significantly higher than for daily or weekly administration. [less ▲]
