A collection of 1601 extraintestinal and intestinal Escherichia coli isolated from chickens, turkeys and ducks. in Belgium, France and Spain, was hybridised with gene probes specific for fimbrial and afimbrial adhesins (F17, F18, S (Sfa/F1C), Bfp, Afa, Cs31A, Intimin (Eae), Aida-1) of intestinal, urinary and invasive E. coli of mammals and with a probe specific for the P (Pap/Prs) fimbrial adhesin of urinary and invasive E. coli of mammals and birds. Three hundred and eighty-three strains (23.9%) were P-positive, 76 strains (4.8%) were Afa-positive, 75 strains (4.7%) were F17-positive, 67 strains (4.2%) were S-positive, 23 (1.4%) were Intimin-positive. and all were F18-, Cs31A-, Aidal- and Bfp-negative. The 75 F17-positive strains harboured different major subunit A-encoding gene variants, but the f17Ac variant was the most frequent (52 strains, 69,3%) and seven strains (9.3%) were not typeable. The f17G gene variant coding for the GII adhesin was the most frequent (56 strains, 75.0%), whereas the f17GI gene variant was present in four strains (5%) and 15 strains (20.0%) were not typeable. All Afa-positive strains harboured the afa-8 variant. The 23 Intimin-positive E. coli tested positive for the beta -variant (16 strains; 69.6%) or for the gamma -variant (seven strains;, 30.4%) of the eae gene. Chicken and turkey E. coli were more frequently probe-positive (43.6 and 43.1 %, respectively) than duck E. coli 31.5%) and extraintestinal E. coli were also more frequently probe-positive (48.4%) than intestinal strains (18.5%). Different combinations of probe positive hybridisation results were observed in 72 of the 540 probe-positive E. coli (13.3%). The most frequent combinations were between AfaE-8 and F17 probes (47 strains; 8.7%) and between P and S probes (13 strains. 2.4%). Although f17- and afa-8-related DNA sequences can be plasmid-located in mammalian E. coli. they were not in avian E. coli. Besides the P fimbrial adhesin, F17 and S fimbrial and Afa-VIII and Intimin afimbrial adhesins may thus represent colonisation factors of avian pathogenic E. coli. (C) 2002 Elsevier Science B.V.

La cryptorchidie affecre environ 1 garçon sur 150 et dans près de 20% des cas, la gonade n'est pas palpée. Lorsqu'il est présent, le testicule non palpable est situé entre l'orifice externe du canal inguinal et le pôle inférieur du rein. Souvent cependant, lors de l'exploration chirurgicale, on constate l'existence de reliquats tissulaires à l'extrémité de vaisseaux spermatiques borgnes sans que l'on puisse reconnaître à proprement parler un testicule: on parle alors de testicule absent. Dans d'autres cas, on ne trouve pas de trace de vaisseau spermatique, de structure épidydimo-déférentielle ou encore de tissu testiculaire; il s'agit d'agénésie gonadique. Le testicule non palpé présente un risque accru d'infertilité, de transformation maliine, de hernies et malformations épididymo-déférentielles associées. Le traitement chirurgical est souvent plus complexe et les échecs plus fréquents. De nombreuses techniques d'imagerie ont été proposées comme modalités diagnostiques pour localiser le/les testicule(s) non palpé(s) (pneumopéritonéographie, angiographie, ultrasonographie, tomodensitométrie computérisée, RMN) mais aucune d'elles, à ce jour, n'est uniformément acceptée en raison du manque de fiabilité à détecter le testicule recherché et/ou des dangers potentiels résultant de leur emploi. Depuis la description par Cortesi en 1976 de l'utilisation de la cælioscopie pour la localisation du testicule impalpable, un intérêt croissant a été porté par les urologues et les chirurgiens pédiatriques à cette technique qui aujourd'hui joue un rôle central dans l'exploration du testicule cryptorchide non palpé. Les auteurs tentent d'établir une méthodologie algorythmique d'investigation des testicules cryptorchides non palpés à la lumière des données anatomiques, pathologiques et chirurgicales récentes de la littérature.

This paper reviews the literature with a view to grounding empirical comparative research on male and female managers' careers with regard to three age categories: managers aged up to 35, between 35 and 50 and above 50. It considers both men and women as professional careers are influenced by gender as well as by stereotyped gender roles. Hence, distinguishing these age categories affords consideration of evolving contextual factors such as gender-specific roles upheld throughout time. Indeed social perceptions with regard to gender can vary from one generation to another and sensibly affect career choices. Thus considering age in correlation with gender leads up to broaching "intersectionality", a concept which in diversity management consists in crossing the target groups concerned. This theoretical overview of the literature relating to the careers of managers yields a theoretical frame of reference along with qualitative propositions to be tested subsequently in the field.

The main purpose of this paper is to argue the extent that earnings management lowers liquidity. It should increase information asymmetry and impair trading liquidity. Using a sample of French firms from 2008 to 2011, we find that firms that manage earnings have wider bid-ask spreads. Our results are robust for both of two well established measures of market liquidity. Therefore the empirical results indicate that firms that exhibit greater earnings management are associated with lower market liquidity. These findings are in line with adverse selection and shed light on the role corporate governance devices can play in the consideration of shareholder interest’s protection, which leads to improved stock market liquidity levels.

The example presented here concerns the audit of a typical, medium-size, office building erected in Brussels at the end of the sixties. This building is equipped with a classical “old fashion” air conditioning system with induction units. An audit procedure is developed and tested “in way”. It consists in a systematic analysis of all information available, with help of very simple calculation. Not all the orders of magnitudes of the fuel and mostly of the electricity consumption can be interpreted, but very significant energy saving opportunities are already discovered. [less ▲]

When testing the fire resistance of metal sandwich panels, the annex B of EN 15254-5 gives rules for the consequently allowed extension of span length. The processing of these rules requires that specific measurements are carried out on joints between panels during the test. When a set of tests has been realised on panels of different thicknesses, but no measurement has been carried out on joints during these tests, the relevance of the following processing is analysed : 1. redo only the tests on panels of minimum and maximum thicknesses and carry out the measurement on joints ; 2. deduce the extended height allowed for these tests ; 3. interpolate these results to panels of intermediate thicknesses.

Galleries excavation leads to damage and significant properties changes of the host rock. The fracture structure of the excavation damaged zone created around the galleries remains nowadays a major issue especially in the context of underground storage. In order to correctly model the strain localisation, the second gradient local model (regularization method) is used within a hydro-mechanical modelling of a gallery excavation. The numerical results provide information about the strain localisation bands pattern. [less ▲]

The drilling of galleries induces damage propagation in the surrounding medium and creates the Excavation Damaged Zone (EDZ) in which the material properties are modified. The prediction of the fracture structure and flow properties evolution within this zone are major issues especially in the context of underground nuclear waste storage. Since experimental results indicate that shear strain localisation appears prior to fractures, we model the EDZ with strain localisation in shear band mode using the coupled local second gradient model. The evolution of the intrinsic hydraulic permeability inside the fractures is taken into consideration as well as the influence of gallery ventilation on the rock desaturation. The numerical results provide information about the damaged zone extension, structure and behaviour with good correspondence to in situ measurements and observations. [less ▲]
