The project aimed at providing synthetic and operational guidelines to the managers of companies willing to begin a procedure of environmental management system (EMS). After an introduction, summarizing the EMS principle, the document presents the different steps of the protocol and the useful recommendations at each step. The different possibilities of assistance are also presented (on-line web sites, teaching or administrative resources). Two annexes are provided : a first one devoted to environmental performance indicators and a second one to the management review writing. [less ▲]

The object of the second phase of the study is a technical support/advise to the construction of a portable prototype equipment for on site segregation of tires at the retreading stage. The final equipment aims at identifying the composition type of the rubber of the treads : either high natural rubber content (>60%) or high synthetic rubber content. An additional goal of the study is to elaborate the functional specifications for a handheld compound analyser to be coupled to the Goodyear viscoelasticity tester. [less ▲]

Enteropathogenic Escherichia coli (EPEC) are isolated from man and farm animals but also from dogs and cats. They produce typical histological lesions called 'attaching and effacing' lesions. Both plasmid and chromosomal elements are involved in the pathogenesis of EPEC infection. The presence of these genetic elements was investigated in 14 dog and three cat EPEC isolates. A bfpA-related gene was detected in five of the 17 isolates in association with high molecular weight plasmids, and a locus of enterocyte effacement (LEE) was present in all isolates. The LEE was inserted in the selC region in only 12% of the isolates. The eae, tir, espA and espB genes were analyzed by multiplex PCR. The results indicated the presence of those genes in the tested isolates with heterogeneity in the gene subtypes present: eae gamma-tir alpha-espA alpha-espB alpha (65%), eae beta-tir beta-espA beta-espB beta (29%), eae alpha-tir alpha-espA alpha-espB alpha (6%). Moreover, the espD gene was also present in dog and cat EPEC. The DEPEC and CEPEC form a heterogeneous group and five of them are closely related to human EPEC. [less ▲]

L’objectif de cette étude est de mieux comprendre et de quantifier (via la modélisation mathématique) les phénomènes qui se déroulent dans le milieu aquatique au droit et en aval des centrales électriques, en particulier les effets du cumul des prises d’eau et rejets thermiques sur l’écosystème aquatique. L'étude concernait les centrales électriques situées sur la Meuse en région wallonne : la centrale de Tihange, la centrale des Awirs, la centrale de Seraing et la centrale d’Angleur. L'étude a été organisée en 2 phases : La première phase comprenait : - la détermination de l'impact élémentaire de chaque centrale et la détermination de scénarios de fonctionnement des centrale - la détermination de l'impact hydrologique et de l'impact thermique (individuel et cumulé) du fonctionnement des centrales électriques sur la Meuse La deuxième phase comprenait : - la détermination de l'impact écologique du fonctionnement des centrales électriques sur l’écosystème Meuse; - l'examen des actions possibles pour minimiser les impacts Ce rapport final reprend les résultats de la deuxième phase de l'étude [less ▲]

The Far Ultraviolet (FUV) instrument on IMAGE images the aurora in three different wavelength regions. The Wideband Imaging Camera (WIC) observes the molecular Lyman-Birge-Hopfield (LBH) and atomic Nitrogen emissions at 140-190 nm. The two channels of the Spectrographic Imager (SI) observe the Doppler shifted Lyman Alpha emission of precipitating protons at 121.8 nm (SI 12) and the mostly electron produced emission from oxygen OI at 135.6 nm (SI13). The major advantage of FUV compared to previously flown UV imagers is the simultaneous operation of all three imaging systems without the need for filter changes and the uncertainty of temporal changes of the aurora between exposures. The FAST satellite passes every two hours through FUV images during apogee operations. This enables a comparison between the remotely imaged particle precipitation and the in-situ measurements along the FAST track. The detailed analysis of images from all three systems together with a full simulation of auroral emissions based on in-situ measurements by FAST confirms the laboratory calibrations of FUV. The spatial resolution and image quality of WIC permits the observation of a good correspondence between in-situ and remote measurements of precipitation boundaries. The clear separation between the lower latitude proton precipitation and the more structured higher latitude electron precipitation is obtained with both SI-channels. [less ▲]

Basic theoretical and practical aspects of activation parameters are briefly reviewed in the context of cold-adaptation. In order to reduce the error impact inherent to the transition state theory on the absolute values of the free energy (DeltaG(#)), enthalpy (DeltaH(#)) and entropy (DeltaS(#)) of activation, it is proposed to compare the variation of these parameters between psychrophilic and mesophilic enzymes, namely Delta(DeltaG(#))(p-m), Delta(DeltaH(#))(p-m) and Delta(DeltaS(#))(p-m). Calculation of these parameters from the available literature shows that the main adaptation of psychrophilic enzymes lies in a significant decrease of DeltaH(#), therefore leading to a higher k(cat), especially at low temperatures. Moreover, in all cases including cold-blooded animals, DeltaS(#) exerts an opposite and negative effect on the gain in k(cat). It is argued that the magnitude of this counter-effect of DeltaS(#) can be reduced by keeping some stable domains, while increasing the flexibility of the structures required to improve catalysis at low temperature, as demonstrated in several cold-active enzymes. This enthalpic-entropic balance provides a new approach explaining the two types of conformational stability detected by recent microcalorimetric experiments on psychrophilic enzymes. [less ▲]

The behavior of mixtures of a nonionic surfactant, pentaethylene glycol monodecyl ether (C10E5), and an anionic surfactant, sodium dodecyl sulfate (SDS), was studied at the water−silica interface. In contrast to the C10E5 surfactant, which is adsorbed at the silica−water interface at pH 6, the adsorption of the anionic surfactant is not observed. In the presence of SDS, the adsorption of C10E5 is severely restricted as result of the formation of mixed micelles in solution. This behavior is consistent with the adsorption free energy, ΔGads, of C10E5 and the free energy of mixed micellization, ΔGmix.mic, of SDS and C10E5. Flow microcalorimetry (FMC) results showed that the addition of C10E5/SDS mixtures to silica precoated with C10E5 resulted in the release of the preadsorbed nonionic surfactant; the whole phenomenon is exothermic. Combination of calorimetric data (FMC and isothermal titration calorimetry), self-diffusion coefficients, and the regular solution theory led to the conclusion that the main driving force for the C10E5 desorption was the formation of mixed micelles by unimeric SDS and the released nonionic surfactant.
