We present the design of DISco, a storage and communication middleware that enables distributed and task-centric autonomic control of networks. DISco allows multi-agent identification of anomalous situations (challenges) and assists coordinated remediation that will maintain service at an acceptable level, although degraded. The history of agents decisions, their context and outcomes is tracked as the situation evolves, and information is automatically gathered and organised to ease further human-assisted diagnosis. We then explore the feasibility of using state of the art peer-to-peer publish/subscribe and storage systems as building blocks for this service. The ability of those systems to support range queries and aggregation will be a key factor for their suitability to the task. [less ▲]

Nous présentons ici des tours de magie ne nécessitant aucune habileté particulière de la part de l'apprenti magicien : des tours de cartes, des tours de divination etc. Contrairement au magicien qui ne dévoile jamais ses secrets, ici, nous expliquons que ces tours reposent sur diverses propriétés et constructions mathématiques (décomposition d'une permutation en produit de cycle, suites linéaires récurrentes, ...). Il y en aura donc pour tous les goûts... et tous les niveaux. Dans la mesure du possible, nous présenterons de "nouveaux" tours qui n'auraient pas déjà été dévoilés dans un exposé précédent.

In this paper we trace some of the key points in the history of Science and Technology Studies (STS). In particular we outline the inherently political dynamics of the field. Against We underline two emerging patterns in the curse of STS: the one of “depoliticisation” and the one of increasing “engagement”. We address the case study nanotechnologies and discuss their intertwined history with the STS. This allows us to point at the risk that the increasing institutionalisation of STS and the political mandate that frames and stabilizes the field’s relationship to the technological developments would create a political void. We conclude that STS research is at a crossroads. It is facing an important empirical turn, which may deprive it from its political significance, and constantly redefine its institutional constraints. STS has to continuously question its underlying political assumptions (as it occurs more and more regarding public participation) and to make it explicit. [less ▲]

Acetic acid bacteria encounter various harsh conditions during acetic acid fermentation. Ethanol as the main substrate and acetic acid as the major product at low pH can influence deeply on the cellular functions of acetic acid bacteria. In previous studies in CWBI, Acetobacter senegalensis was used for production of dried vinegar starters; however the impact of stressors (ethanol and acetic acid) on A. senegalensis remained unclear. In this study, different techniques such as flow cytometry, culturability on solid medium and 2-DiGE were used comparatively to investigate the effect of carbon sources of inoculum media on the tolerance of A. senegalensis to stressors. Analysis of respiration system by flow cytometric methods showed that the presence of 2% (v/v) acetic acid in inoculum medium, in one hand, causes 80% of cells to continue to do respiration after a sudden exposure to 1- 3% (v/v) acetic acid in stress media while 89.7% of cells grown in glucose appeared as dead cells after an abrupt exposure to 3%(v/v) of acetic acid. On the other hand, 59.2% and 49.33% of cells grown in the presence of 2% (v/v) of acetic acid could maintain their entire membrane integrity after exposure to 1% and 3% (v/v) of acetic acid, respectively. Inoculum medium contained 5% (v/v) of ethanol as a carbon source enabled about 90% of cells to keep their growing capacities after a sudden exposure to 3% acetic acid. In contrast, just 40% of cells grown in glucose as a carbon source maintained their culturability on solid medium after exposure to 1% acetic acid. A similar profile of culturability was observed for the cells grown in 5% (v/v) ethanol or 2% (v/v) of acetic acid. A proteomic approach (2-DiGE) was used to analyze proteins expressed in the presence of different carbon sources. Differentially expressed proteins were mainly associated with energy metabolism, carbohydrate metabolisms, folding, sorting and degradation processes. The relative abundance of proteins was extensively different for cell grown in glucose compared with protein contents of cells grown in ethanol or acetic acid. In conclusion, production of a cost effective vinegar starter needs a qualified biomass which tolerates ethanol and acetic acid. Tolerance of A. senegalensis to acetic acid depends to a great extent on the composition of the medium which cells grow in. In spite of low adaption to acetic acid for cell grown in glucose, using ethanol or acetic acid in inoculum media renders a physiological state in A. senegelensis which enables it to cope with higher concentration of acetic acid readily, this biomass has a potential to be used as a starter [less ▲]

To reduce the chromatic aberration lots of imaging systems like cameras and telescopes turn to achromatic doublets. On the other hand, to be cheaper, lighter and thinner, more and more systems like projectors and headlights use Fresnel lenses. To combine high performances and low cost, the use achromatic Fresnel doublets has been investigated. [less ▲]

The effect of heat treatments (drying and hydrothermal treatment) on the extractability of salt-soluble protein (SSP) was assessed using Promatest methodology for corn kernels heated between 60 C and 120 C. During drying, the evolution of the grain moisture content is fitted using the analytical solution of Fick equation developed by Crank (1979) for spherical material. The decrease of extractible salt-soluble protein during heating is forecasted using a first and a second order ordinary differential equation. It was found that temperature; moisture content and time of processing greatly influence the kinetic denaturation of SSP of corn kernels. The evolution of extractible SSP content of corn kernels during drying at high temperature is more correctly described with second order kinetic than with the first order kinetic reaction. The Hunterlab color parameters of corn also vary during drying. Lightness and color intensity decrease while yellowness, redness, chroma and hue angle increase through drying time. Most of these Hunterlab color parameters are highly correlated with the salt-soluble proteins content and therefore could be used as indicators of excessive heat treatment and denaturation of salt-soluble proteins in corn kernels [less ▲]

Given their high apparent variability, bedside continuous respiratory mechanics (RM) parameters (excepting tidal volume (VT)) remain infrequently used for adjustment of neonatal ventilatory settings. RM parameters provided by ventilator (VRC) from 10 recordings of newborns (10 minutes in synchronized intermittent mandatory ventilation and Assist/control (A/C)) were compared to those computed from visually selected assisted leak-free optimal respiratory cycles (SRC). Mean values, variability and ability to distinguish patients were compared between VRC and SRC. Dynamic resistances were more correlated (r²=0.95) than compliances (r²=0.42). VT’s were correlated only in A/C (r²=0.78). C20/C was significantly higher in VRC (1.81±0.67) than in SRC (1.23±0.36) and frequently out of neonatal reference range. In A/C ventilation, VT was higher in VRC (5.6 ±1.8 ml/kg) than in SRC (4.8 ±1.0 ml/kg) (p<0.05). Displayed VT’s don’t reflect those found in optimal assisted breaths and therefore have incomplete value in assessing adequacy of ventilator settings. The variability of RM parameters provided by the ventilator is large, and coefficients of variation were significantly lower with optimal respiratory cycles (for Resistance, Compliance, VT and C20/C: 27, 26, 18, 24% in SRC, 36, 35, 40, 33% in VRC). Selecting optimal cycles yields RM with a 2-3 times higher discriminating power between patients. Conclusion: Current ventilator’s RM parameters have limited clinical use. Using optimal breaths to calculate RM parameters improves precision and discriminating power. For integration to ventilatory care, automation of this selection must be implemented first. [less ▲]
