The daily intakes (DI) were estimated in a Belgian general population for 5 phthalates, namely diethyl phthalate (DEP), di-n-butyl phthalate (DnBP), di-iso-butyl phthalate (DiBP), butylbenzyl phthalate (BBzP) and di-2-ethylhexyl phthalate (DEHP), based on the urinary measurements of their corresponding metabolites. DI values ranged between <LOD and 59.65 μg/kg bw/day depending on the congener, and were globally higher for children than adults. They were compared to acceptable levels of exposure (tolerable daily intakes) to evaluate the hazard quotients (HQ), which highlight an intake above the dose considered as safe for values greater than 1. If very few of our Belgian participants exceeded this threshold for phthalates considered individually, 6.2% of the adults and 25% of the children showed an excessive hazard index (HI) which took into account the cumulative risk of adverse anti-androgenic effects. These results are of concern since these HI were based on only 3 phthalates (DEHP, DiBP and DnBP), and showed a median of 0.55 and 0.29 for children and adults respectively. The comparison with previously determined dietary intakes demonstrated that for DEHP, food intake was nearly the only route of exposure while other pathways occurred mainly for the other studied phthalates.

Saccharomyces cerevisiae C8-5 and Candida tropicalis F0-5 isolated from traditional sorghum beer were tested for kinetic parameters on barley malt extract, YPD (863 medium) and for alcohol production. The results showed that C. tropicalis has the highest maximum growth rate and the lowest doubling time. Values were 0.22 h-1 and 0.32 h-1 for maximum growth rate, 3 h 09 min and 2 h 09 min for doubling time respectively on barley malt extract and YPD. On contrary, glucose consumption was the fastest with S. cerevisiae (-0.36 g/l/h and -0.722 g/l/h respectively on barley malt extract and YPD). When these two yeasts were used as starters in pure culture and co-culture at proportion of 1:1 and 2:1 (cell/cell) for barley malt extract fermentation, we noticed that maltose content increased first from 12.12 g/l to 13.62-16.46 g/l and then decreased. The highest increase was obtained with starter C. tropicalis + S. cerevisiae 2:1. On contrary, glucose content decreased throughout all the fermentation process. For all the starters used, the major part of the ethanol was produced at 16 h of fermentation. Values obtained in the final beers were 11.4, 11.6, 10.4 and 10.9 g/l for fermentation conducted with S. cerevisiae, C. tropicalis, C. tropicalis + S. cerevisiae 1:1 and C. tropicalis + S. cerevisiae 2:1. Cell viability measurement during the fermentation by using flow cytometry revealed that the lowest mean channel fluorescence for FL3 (yeast rate of death) was obtained with C. tropicalis + S. cerevisiae 2:1 after 48 h of fermentation.

This paper aims at studying the effect of corporate disclosures on information asymmetry and stock-market liquidity in France. Specifically, the purpose of this paper is to highlight the importance of information included in the annual reports on investor’s behavior. This is proxied by the information asymmetry component of the bid-ask spread and stock market liquidity. Our sample includes 196 French listed firms over a period ranging from 2004 to 2007. We opt for an explanatory study using OLS regressions to examine the nature of the relationship between information disclosed in annual reports and bid-ask spreads a proxy for information asymmetry and stock market liquidity. The results show that the extent of corporate disclosures in annual reports positively influences the liquidity of the French market and negatively affects the adverse selection component of the bid-ask spread. This effect is further confirmed by the commitment to IFRS by French-listed firms from 2005. The decomposition of the total score in the sub-indices shows that non-financial and financial information are important in trading decisions while strategic information may be attractive only for long-term positions [less ▲]

Although mobility management by employers is an increasingly common practice, literature is scarce on the real impact of the applied measures. In this perspective, the objective of this paper is to assess the impact on car use of the measures adopted by employers located in Wallonia. In order to achieve this objective, the article develops simulations that put forward the impact of the measures based on their interrelations with other modal choice factors. Our assessment leads to the conclusion that measures promoting public transport and car-pooling can reduce solo car driving between 7,2 % and 8,4 %. In contrast to our assumption, measures promoting public transport are less effective in central areas than in urban outskirts. Regarding measures promoting the use of bicycle, the findings suggest that the modal shift occurs from other modes rather than from car use. [less ▲]

Lignin is a co-product from the biorefinery and paper industry. Its non-energetic valorization remains a field of extensive R&D developments. In this perspective, this study is undertaken to evaluate the radical scavenging ability of some herbaceous lignins. These lignins, extracted from Miscanthus (Miscanthus x giganteus) or Switchgrass (Panicum Virgatum L.), are selected as benchmarks for this study as a function of their chemical structure and average molecular weight. These technical lignins, side-products in the bioethanol production process, are found to display a moderate antioxidant activity as evaluated by the DPPH (1,1-diphenyl-2-picrylhydrazil) free radical scavenging test system. A correlation between the radical scavenging properties and the molecular features is proposed and discussed. Infrared spectroscopy is evaluated as a straightforward qualitative prediction tool for the radical scavenging capacity. [less ▲]

Mon ambition est de mettre en lumière quelques traits distinctifs du programme d’analyse de l’esprit développé par Franz Brentano et les membres de son école. Plus spécialement, je suggérerai qu’il y a un sens à parler d’une authentique phénoménologie brentanienne. J’entends par là un programme de recherche original, distinct notamment de la phénoménologie de Husserl – qui, à partir de 1903, n’est plus conçue comme une psychologie empirique ni, a fortiori, comme une psychologie expérimentale – et de la « phénoménologie » de Stumpf – qui, se rattachant à la tradition plus ancienne d’une Empfindungslehre, désigne exclusivement l’étude des phénomènes sensibles ou des matériaux sensoriels . Ma conviction est qu’un examen attentif des caractéristiques propres à la phénoménologie ou psychologie descriptive d’inspiration brentanienne est une bonne manière de donner un sens à l’expression de « phénoménologie autrichienne » qui a été proposée, dans la littérature, pour désigner le champ d’investigation ouvert par Brentano et les brentaniens.

Apple (Malus sp.) is among the most processed fruit that generates high amount of wastes. Depending on processes, various by-products are available offering a great diversity of low-cost raw materials. Biorefinery processes are expected to convert them into new added-value products such as hemicelluloses, oligosaccharides and polyphenols. This paper reviews the current uses of apple by-products as source of fibre and phytochemicals with special emphasis on recent fractionation processes. Future trends and challenges of apple by-product reuse are discussed. [less ▲]

HD76431 is a slow rotating post-HB star that shows an underabundance of helium by 0.5 dex relative to the solar value. These observational facts suggest that atomic diffusion could be active in its atmosphere. We have used the MMT and Bok spectra to estimate the atmospheric parameters of the target star using the model atmospheres and synthetic spectra calculated with TLUSTY and SYNSPEC. The derived values of the effective temperature, surface gravity, helium abundance are consistent with those obtained by Ramspeck et al. (2001b). It appears that NLTE effect are not important for HD76431. We have used Stokes I spectra from ESPaDOnS at CFHT to perform an abundance analysis and a search for observational evidence of vertical stratification of the abundance of certain elements. The results of our abundance analysis are in good agreement with previously published data with respect to average abundances. Our numerical simulations show that carbon and nitrogen reveal signatures of vertical abundance stratification in the atmosphere of HD76431. It appears that the carbon abundance increases toward the deeper atmospheric layers. Nitrogen also shows a similar behaviour, but in deeper atmospheric layers we obtain a significant dispersion for the estimates of its abundance. To our knowledge, this is the first demonstration of vertical abundance stratification of metals in a post-HB star and up to now it is the hottest star to show such stratification features. We also report the detection of two SiIII and one TiIII emission lines in the spectra of HD76431 that were not detected in previous studies. [less ▲]

This case study analyses how far donors implement aid effectiveness principles at health district level in Mali, and why. It shows that not all aid effectiveness principles are implemented at a similar degree. Most projects have limited impact on health services, but many programmes supported by donors offer positive opportunities for health system strengthening. The representations of different categories of stakeholders diverge – notably, regarding the role of different actors in service provision. A number of consistent strategic logics influence actors’ behaviour. We show that while many donors have committed at global level to respect aid effectiveness principles, implementation lags behind.
