To prioritize 100 animal diseases and zoonoses in Europe, we used a multicriteria decision-making procedure based on opinions of experts and evidence-based data. Forty international experts performed intracategory and intercategory weighting of 57 prioritization criteria. Two methods (deterministic with mean of each weight and probabilistic with distribution functions of weights by using Monte Carlo simulation) were used to calculate a score for each disease. Consecutive ranking was established. Few differences were observed between each method. Compared with previous prioritization methods, our procedure is evidence based, includes a range of fields and criteria while considering uncertainty, and will be useful for analyzing diseases that affect public health [less ▲]

This paper presents a new technique to identify the damping of linear systems. It is developed from the Proper Orthogonal Decomposition (POD) of the free response of the system and extended to the recently proposed Common-base POD (CPOD). The present application of CPOD considers simultaneously several free responses of the system to different initial conditions. The eigen-decomposition of the co-variance matrix leads to a unique vector basis which is likely to contain more information about the dynamics of the system than a vector basis obtained by the classic POD technique. The ability of the technique to estimate the mode shapes and the modal damping is demonstrated on a simulated mass-spring-damper system. Two different distributions of masses are considered in order to confront the CPOD analysis to the intrinsic limitation of POD, i.e. that the mode shapes are identified exactly only if the mass matrix is proportional to the identity matrix. It is shown that the identification of the damping is still possible when the modes are not orthonormal. The robustness of the technique is demonstrated in the presence of noise in the responses of the system and through an experimental application with comparison with other identifications techniques.

In his writings concerned with biopolitics Foucault gives the concept of population a central place and means to find its arising at the crossroads of several types of discourse : particularly about species and the public. The genealogy of this bifocal concept is in keeping with some aspects of Canguilhem’s epistemological approach to the regulation of milieus, following his work on scientific ideology. Not only does such a parallel enable us to bring out the critical use of biopolitical concepts, it also leads us to examine the technological sequence which has made it possible for the concept of population to be determined. Such a sequence is articulated in three moments – utopia, practice, theory – which enable us to account for the evolution of the technology of police. [less ▲]

The diet of the Malachite Kingfisher was investigated by study of 182 regurgitated pellets collected from 65 broods during the nesting period in the rainy seasons from 2004 to 2009, in two sites in the Kinshasa area. In total, 2619 undigested remains were identified in the pellets, revealing 1100 prey. The Malachite Kingfisher’s diet is rich and diverse. The prey identified were 92.7 % fishes (Oreochromis niloticus, Gambusia affinis and Hemichromis elongatus), 5.9 % insects (Odonata and Orthoptera) and 0.5 % frogs. [less ▲]

Microtubule dynamics is regulated by an array of microtubule associated proteins of which the microtubule plus-end tracking proteins (+TIPs) are prominent examples. +TIPs form dynamic interaction networks at growing microtubule ends in an EB1-dependent manner. The interaction between the C-terminal domain of EB1 and the CAP-Gly domains of the +TIP CLIP-170 depends on the last tyrosine residue of EB1. In the present study, we generated peptidic probes corresponding to the C-terminal tail of EB1 to affinity-capture binding partners from cell lysates. Using an MS-based approach, we showed that the last 15 amino-acid residues of EB1, either free or immobilized on beads, bound recombinant CAP-Gly domains of CLIP-170. We further demonstrate that this binding was prevented when the C-terminal tyrosine of EB1 was absent in the peptidic probes. Western blotting in combination with a label-free quantitative proteomic analysis revealed that the peptidic probe harboring the C-terminal tyrosine of EB1 effectively pulled-down proteins with CAP-Gly domains from endothelial cell extracts. Additional proteins known to interact directly or indirectly with EB1 and the microtubule cytoskeletonwere also identified. Our peptidic probes represent valuable tools to detect changes induced in EB1-dependent +TIP networks by external cues such as growth factors and small molecules. [less ▲]

This report is part of a PhD thesis currently taking place at the University of Liège in collaboration with the company Laborelec. A Degradation Test Rig (DTR) has been built in order to evaluate solvent degradation in CO2 capture conditions. Details about degradation effects and about the DTR may be found in a previous report (PhD mid-term report, G. Léonard, 2011). Experiments to study the effect of process conditions on degradation are in progress with 2-ethanolamine (MEA) as benchmark solvent. This report presents first a brief overview of the different degradation mechanisms and associated products, followed by a literature review about metal influence on MEA degradation and a state of the art review about degradation inhibitors.

The paper singles out the key roles of US equity skewness and kurtosis in the determination of the market premia embedded in Hedge Fund returns. We propose a conditional higher-moment asset pricing model with location, trading and higher-moment factors in order to describe the dynamics of the Equity Hedge (Market Neutral, Short Selling and Long/Short strategies), Event Driven, Relative Value, and Funds of Hedge Funds styles. The volatility, skewness and kurtosis implied in the US options markets are used by Hedge Fund managers as instruments to anticipate market movements. Managers should adjust their market exposure in response to variations in the implied higher moments. We show that higher-moment premia improve a conditional asset pricing model both in terms of explanatory power (R-squares and Schwarz criterion) and specification errors across all Hedge Fund styles.

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 ▲]

The many recently published data on vitamin D have raised much interest in the medical community. One of the consequences has been a great increase in the prescription of vitamin D concentration measurements in clinical practice. It must be reminded that only the measurement of 25-hydroxyvitamin D (25(OH)D) concentration is indicated to evaluate vitamin D status. Furthermore, since vitamin D insuffi ciency is so common, since treatment is inexpensive and has a large safety margin, and since we already have much data suggesting that besides its classic effects on bone and mineral metabolism, vitamin D may potentially be helpful for the prevention/management of several diseases, perhaps should it be prescribed to everyone without prior testing? In our opinion, there are however groups of patients in whom estimation of vitamin D status is legitimate and may be recommended. This includes patients in whom a “ reasonably ” evidence-based target concentration (i.e., based on randomized clinical trials when possible) should be achieved and/or maintained such as patients with rickets/osteomalacia, osteoporosis, chronic kidney disease and kidney transplant recipients, malabsorption, primary hyperparathyroidism, granulomatous disease, and those receiving treatments potentially inducing bone loss. Other patients in whom vitamin D concentration may be measured are those with symptoms compatible with a severe vitamin D defi ciency or excess persisting without explanation such as those with diffuse pain, or elderly individuals who fall, or those receiving treatments which modify vitamin D metabolism such as some anti-convulsants. Measurement of Vitamin D concentrations should also be part of any exploration of calcium/phosphorus metabolism which includes measurement of serum calcium, phosphate and PTH. [less ▲]
