Physical, psychological and economical consequences of urinary incontinence of the elderly woman are underestimated. It often results in depression, social isolation and early institutionalisation. It is often the key factor that determines the decision of institutionalisation, which represent the most important part of the total cost of urinary incontinence. This problem is too often neglected and deserves considerable attention. [less ▲]

Opportunities for updating and optimizing current operating rules are being evaluated for the Vesdre reservoirs in Belgium (50 M m³) and the Rur complex in Germany (300 M m³). This assessment is conducted transnationally at the scale of the Meuse river basin. Common methodological approaches are followed in both countries and operating rules are analyzed in light of common climate change scenarios, recently defined for the whole Meuse basin. Similar risk-based approaches are used consistently in both countries to evaluate the performance of new operating rules in terms of risk reduction for floods and low flows. [less ▲]

In this paper we use annual data on 92 French electricity distribution units (2003-2005) to estimate a benchmarking model that includes a quality of service indicator (number of interruptions). Our methodology involves the estimation of input distance functions using stochastic frontier analysis (SFA) and data envelopment analysis (DEA) techniques. The empirical results indicate that the inclusion of the quality variable has no significant effect upon mean technical efficiency scores, and the mean shadow price of one interruption is approximately ten Euros. The analysis in this paper is the first preliminary step in a larger project which is investigating the feasibility of including quality measures into benchmarking models that are often used by regulatory authorities [less ▲]

his paper deals with the incorporation of a vector hysteresis model in 2D finite-element (FE) magnetic field calculations. A previously proposed vector extension of the well-known scalar Jiles-Atherton model is considered The vectorised hysteresis model is shown to have the same advantages as the scalar one: a limited number of parameters (which have the same value in both models) and ease of implementation The classical magnetic vector potential FE formulation is adopted Particular attention is paid to the resolution of the nonlinear equations by means of the Newton-Raphson method It is shown that the application of the latter method naturally leads to the use of the differential reluctivity tensor, i.e. the derivative of the magnetic field vector with respect to the magnetic induction vector. This second rank tensor can be straightforwardly calculated for the considered hysteresis model. By way of example, the vector Jiles-Atherton is applied to two simple 2D FE models exhibiting rotational flux. The excellent convergence of the Newton-Raphson method is demonstrated. [less ▲]

Until now, wild-type bacteriophage lambda lysozyme had been impossible to crystallize. This difficulty could be overcome by the replacement of the four tryptophan residues by azatryptophans. Analysis of the intermolecular and intramolecular contacts in this modification allows understanding of the differences in behaviour between the native and modified molecules. Furthermore, this mutation was very useful for the creation of new heavy-atom binding sites and for the solution of the non-crystallographic symmetry, which is extremely important for phase improvement. This procedure seems to be generally applicable, at least in the search for new possibilities for heavy-atom binding sites. [less ▲]

This study reports concentrations of iron (Fe) and organic matter in young Antarctic pack ice and during its initial growth stages in situ. Although the importance of sea ice as an Fe reservoir for oceanic waters of the Southern Ocean has been clearly established, the processes leading to the enrichment of Fe in sea ice have yet to be investigated and quantified. We conducted two in situ sea-ice growth experiments during a winter cruise in the Weddell Sea. Our aim was to improve the understanding of the processes responsible for the accumulation of dissolved Fe (DFe) and particulate Fe (PFe) in sea ice, and of particulate organic carbon and nitrogen, dissolved organic carbon, extracellular polymeric substances, inorganic macro-nutrients (silicic acid, nitrate and nitrite, phosphate and ammonium), chlorophyll a and bacteria. Enrichment indices, calculated for natural young ice and ice newly formed in situ, indicate that during Antarctic winter all of the measured forms of particulate matter were enriched in sea ice compared to underlying seawater, and that enrichment started from the initial stages of sea-ice formation. Some dissolved material (DFe and ammonium) was also enriched in the ice but at lower enrichment indices than the particulate phase, suggesting that size is a key factor for the incorporation of impurities in sea ice. Low chlorophyll a concentrations and the fit of the macro-nutrients (with the exception of ammonium) with their theoretical dilution lines indicated low biological activity in the ice. From these and additional results we conclude that physical processes are the dominant mechanisms leading to the enrichment of DFe, PFe, organic matter and bacteria in young sea ice, and that PFe and DFe are decoupled during sea-ice formation. Our study thus provides unique quantitative insight into the initial incorporation of impurities, in particular DFe and PFe, into Antarctic sea ice. [less ▲]

The electrical resistivity tomography (ERT) inverse problem is ill-posed leading to non-uniqueness of its solution. A possible way to reduce the amount of mathematical solutions to more geologically plausible models is to incorporate priori information in the inversion process. In this presentation, we describe the implementation of three different techniques ways to go beyond standard Occam’s inversion for ERT with the code CRTomo : a simple reference model weighted by a user-defined parameter, a structural constraint defined by modifying the construction of the roughness matrix compared to standard Occam’s inversion and a geostatistical constraint based on a vertical correlation length deduced from borehole data to build the model covariance matrix and use it to regularize the inversion. With several examples, we show that the traditional smoothness constraint yield small contrasts of resistivity, far from the reality revealed by borehole measurements. Incorporating prior information from boreholes clearly or from another geophysical technique (like GPR or seismic refraction) improves the misfit with logging data. The choice of the prior information incorporation technique highly depends on which king of information is available and further developments are needed to extend the techniques to more complex cases.

Intake, digestibility, degradation kinetic and fermentation were studied with bulls offered fattening diets with four different incorporation rates of rapeseed meal obtained by pressure; the ether extract content was 8.6% and the glucosinolate content 17,6 mu molg. The control diet was made of sugar beet pulp, cereals, soya bean meal and linseed meal. In the three other diets, nitrogen from rapeseed meal provided 33, 66 or 100% of nitrogen from soya bean meal or linseed meal. The intakes of the control diet were 94.3 +/- 7.3 g/kg metabolic body weight. Intakes were maintained high in the diet with 33, 66 or 100% of protein from rapeseed meal at 93.5 +/- 7.7; 93.0 +/- 5.0 and 93.5 +/- 7.7 g/kg, respectively. The apparent digestibility of rapeseed meal in the ration containing only rapeseed meal was high at 74.9 +/- 1.9% for dry matter, 76.5 +/- 2.1% for organic matter, 69.9 +/- 3.9% for nitrogen, 59.1 +/- 4.8% for ADF and 74.6 +/- 6.9% for ether extract. Dry matter of rapeseed meal was less degradable (57.8 +/- 5.0%) than that of soya bean meal (65.5 +/- 2.6%) or of linseed meal (61.6 +/- 4.2%) but was not as well protected than that of protected soya bean meal (43.6 +/- 2.6%) (P < 0.001). Similar trends were observed for the degradability of nitrogen (P < 0.001). Ether extract of rapeseed meal was more degradable than that of linseed meal (P < 0.001). There were no significant effects of the incorporation rate of rapeseed meal on the pH in the rumen. The fermentations were mainly of the acetate type with usual concentrations of propionate, butyrate, total volatile fatty acids, glucose or alpha amino nitrogen. Ammonia concentration was higher with the control diet and lower with the diet with 100% of protein from rapeseed meal. Fatty acids of rapeseed meal were more protected against saturation by the rumen microorganisms than in linseed meal. [less ▲]

Eight bulls from the Belgian Blue breed were offered diets in which soya bean meal and linseed meal were substituted by rapeseed meal (variety Samourai) in order to provide, respectively, 33, 66 and 100% of the protein. The glucosinolate content was equal to 17.6 mu mol/g dry matter. Analyses of wet residues from rapeseed meal incubated in the rumen showed a rapid decrease of the glucosinolate content which disappeared after 5 h of incubation. The 3-hydroxypent-4-enenitrile, the but-3-enylisothiocyanate and the 5-vinyl-1,3-oxazolidine-2-thione antinutritional factors obtained from the glucosinolates were identified by GC-MS during the first 5 h. The 3-phenylpropanenitrile, the 3-methylindol, the 2-phenylacetic and 3-phenylpropanoic acids were also present in the residues and in the rumen. Although high sensitivity of the methods were used, no glucosinolates and their direct breakdown products were detected in the liquid and the solid content of the rumen. [less ▲]

Postmenopausal osteoporosis is a progressive disorder characterized by a decreased bone mass and increased susceptibility to fractures. Several investigations have suggested that one of the mechanisms through which estrogen prevents bone loss was a modulation on secretion or release of various cytokines that are known to influence bone remodeling, even if some recent data have challenged this hypothesis. However, in established osteoporosis, the possibility that enhanced cytokines activity may account for the progression of this disease remains unclear and controversial. We sought here to determine whether production of IL-1 beta, IL-6, TNF-alpha, IFN-gamma, GM-CSF and LIF, after direct stimulation in whole blood, was different in healthy (n = 30) or osteoporotic postmenopausal women (n = 24) and whether lumbar bone density (1-BMD) correlated with the values of cytokine production observed in these conditions. A significant difference was observed between the osteoporotic and control subjects for IL-1 beta (p < 0.0001), IL-6 (p < 0.001) and TNF-alpha (p = 0.027) productions, the values being higher in the osteoporotic women. No significant differences between the groups were observed for IFN-gamma (p = 0.51), GM-CSF (p = 0.70) or LIF (p = 0.97). In the whole population, statistically significant negative correlations were observed between lumbar BMD and IL-1 beta (r = -0.46) (p < 0.0005), IL-6 (r = -0.50) (p < 0.0001) and TNF-alpha (r = -0.39) (p < 0.005) production while no such correlations were observed for IFN-gamma, GM-CSF or LIF. In conclusion, the study of cytokine production by immune cells cultured in autologous whole blood suggests that in women more than 10 years past the menopause and presenting a decrease in lumbar bone density corresponding to the new WHO definition of "osteoporosis', production of IL-1 beta, IL-6 and TNF-alpha is still increased compared to controls matched for age and ovarian function, while no differences are reported for IFN-gamma, GM-CSF or LIF production.
