Introduction: Non-traumatic neuromuscular lesions of only one muscular portion of the quadriceps are rare and poorly described in literature. Aim: The goal of our study was to investigate the possible causes of this pathology and to objectively quantify the functional consequences of this isolated atrophy from the rectus femoris on the total muscular performances of the quadriceps. Patient and Method: A male patient, 44 years old, presented an isolated atrophy of the right rectus femoris without pain nor history of previous traumatic event. He reported occasional paraesthesias on anterior right thigh. Electromyographic exploration of the lower limbs, imagery (echography and MRI) and isokinetic test were undertaken by the patient. Results: Imagery explorations showed the atrophy of the right rectus femoris combined with fatty degeneration but this exam did not allow determining the actual etiology. Therefore, a precise diagnosis was not allowed, even if the EMG confirmed the presence of important signs of specific and isolated denervation only in the right rectus femoris. The isokinetic test, performed in the classical sitting position, highlighted symmetrical performances for flexors of the knee and a moderately decrease in the right concentric quadriceps torque (-10%). A complementary isokinetic assessment, in a lying supine position, demonstrated a more marked deficit of this right quadriceps (higher than -30%). Conclusion: No precise etiology was shown for this isolated atrophy of the right rectus femoris. Nevertheless, we brought back the importance to lay the patient in a lying supine position in order to preferentially investigate the rectus femoris performances through an isokinetic test. [less ▲]

The European Court of Justice clarified through this judgment the way in which the overloading of a Member States’ asylum system affects the EU arrangements for determining the Member State responsible for asylum applications lodged in the EU and thereby drastically reduced the possibility granted to Member States to transfer asylum applicants. The Member States now have an obligation to verify that no serious risk of violation of the Charter rights of the applicant exits in the receiving country before being allowed to transfer the person. The practical consequences of this ruling are still uncertain but further cooperation between Member States should be able to enhance the level of protection of human rights within the Common European Asylum System.

Nowadays, the widespread use of silage has led to an increased frequency of bacterial contamination of Listeria spp in ruminants. The infection of ruminants is essentially linked to the consumption of silage of poor quality or of milk products. The disease is frequent and severe in ruminants and can be present in various forms: nervous, septicaemic, genital, mastitis and ocular. The ocular form of Listeriosis can serve as a sentinel for the disease at the herd level. In this case report, 2 herds were investigated for calves and adult mortalities. In the first case, a large majority of the calves presented with hypopion but neurological examination of the calves revealed no abnormalities. The majority of the dairy cows also presented with ocular disorders but neurological examination did not reveal any abnormalities. Calves received whole milk from the dairy herd. The dairy herd diet comprised maize and grass silage, and cereals. Listeria monocytogenes was found in milk and grass silage in significant amounts. In the second case, weight loss, abortions and mortalities in adult cattle were reported. Fifty percent of animals examined presented with hypopion, and/or keratoconjunctivitis, and/or uveitis. No neurological abnormality was found. The animals’ ration of was comprised grass and maize silages. The grass silage had poor macroscopical aspect. Analysis revealed the presence of Schizophyllum commune (fungus) and L. monocytogenes in significant amounts. Furthermore, analysis of aborted foetuses also showed L. monocytogenes. Listeria infection in cattle can occur through ingestion of contaminated silage but calves can also be infected throughout the dams’milk. Ocular lesions are not pathognomonic for Listeriosis but, accompanied with abortions and poor quality silage, this can be a major indication for ancillary exams for Listeria monocytogenes at a herd level.

Metabolic abnormalities occur frequently in patients treated with antipsychotics and are of growing concern to clinicians. This study sought to determine whether antipsychotic-associated metabolic abnormalities identified through intensive monitoring can be reversed by switching to aripiprazole. Recent evidence suggests that aripiprazole may exhibit a favorable metabolic safety profile. The study population is a subset of a large (n > 500) ongoing prospective cohort. Thirty-one consecutive patients with schizophrenia who were started on aripiprazole were included in the study. All patients underwent an extensive metabolic evaluation, including an oral glucose tolerance test, at baseline, at 6 weeks, and at 3 months post switch. Metabolic abnormalities were defined as any of the following: new onset diabetes, impaired fasting glucose, impaired glucose tolerance, metabolic syndrome (MetS) according to various definitions, and dyslipidemia. After 3 months of treatment with aripiprazole (mean daily dose 16.3 mg), there was a significant decrease in body weight, body mass index, and waist circumference. There was a significant reduction in fasting glucose, fasting insulin, insulin resistance index, and serum lipids levels (cholesterol, triglycerides, low-density lipoprotein (LDL), LDL/HDL, Chol/HDL, and non-HDL cholesterol). There was also a significant reduction in prolactin levels. All 7 cases of recent onset diabetes were reversed at 3 months follow-up. The MetS was reversed in 50% of patients at 3 months follow-up. Our results support the reversibility of recent onset diabetes on antipsychotic medication when detected early and followed by a switch to aripiprazole. [less ▲]

In this work measurements of random-incidence scattering coefficients in three laboratories are compared. The sample geometry is sinusoidal. These surfaces are geometrically identical, but they were constructed in different scales. So far, measurements of this kind were performed only in scale models. Using turntables in real sample size was hardly considered possible. One result of general importance is that measurements are indeed possible in real-scale reverberation rooms with turntables of 3 m diameter. There are only small differences between the real-scale and model-scale results. Some variations of the standard procedure were tested and the uncertainties identified: mounting of the sample, connection or sealing between sample and base plate, way of rotating the sample, air absorption and time variances. The results presented can be regarded as guidelines for application of ISO/DIS 17497-1. [less ▲]

Many geophysical inverse problems are ill-posed and their solution non-unique. It is thus important to reduce the amount of mathematical solutions to more geologically plausible models by regularizing the inverse problem and incorporating all available prior information in the inversion process. We compare three different ways to incorporate prior information for electrical resistivity tomography (ERT): using a simple reference model or adding structural constraints to Occam's inversion and using geostatistical constraints. We made the comparison on four real cases representing different field applications in terms of scales of investigation and level of heterogeneities. In those cases, when electromagnetic logging data are available in boreholes to control the solution, it appears that incorporating prior information clearly improves the correspondence with logging data compared to the standard smoothness constrain. However, the way to incorporate it may have a major impact on the solution. A reference model can often be used to constrain the inversion; however, it can lead to misinterpretation if its weight is too strong or the resistivity values inappropriate. When the computation of the vertical and/or horizontal correlation length is possible, the geostatistical inversion gives reliable results everywhere in the section. However, adding geostatistical constraints can be difficult when there is not enough data to compute correlation lengths. When a known limit between two layers exists, the use of structural constrain seems to be more indicated particularly when the limit is located in zones of low sensitivity for ERT. This work should help interpreters to include their prior information directly into the inversion process through an appropriate way. [less ▲]

The combined production of heat and power using cogeneration systems is one of the investigated area to reduce the global CO2 production of the industrial activities in Europe. Due to the time scale of the investment, the appropriate sizing of a cogeneration unit is critical for defining the financial feasibility of the project. The possible efforts that could be made during this time scale for improving the enorgy efficiency of the process can make the cogeneration system oversized or even useless. In this paper, we present two methods that we applied to compute the appropriate size of a cogeneration system to be integrated to an industrial site. The first is directly based ôn the present steam consumption figures. This approach is easier and simpler but the solution is not sure for the future, it leads to a 5.6 MW gas turbine but without reducing the overall energy requirements of the plant. The second is based on energy integration including the optimal use of the steam network for CHP. This approach has the advantage to provide a reliable solution for the future. Using this approach, we have computed an energy savings potential of 60Vo, the energy requirements being satisfied by a 4.6 MW gas turbine, and the possibility of producing a complementary 3 MW with steam turbines.

This paper presents the Solar-2002 zero impact renovation project in Belgium. Its characteristics are based on fundamental principles taking advantage of natural resources by diverting the sun shine and rain in the building design. The building has been renovated aiming to achieve principals of occupant health and comfort, energy efficiency, renewable energy production, resource conservation and reduction of environmental impacts. The paper reviews the design concepts including the passive and active strategies and compare building actual performance to actual monitoring results. Innovations related to architectural design, building system performance and simulation are presented. Results show that the house achieved energy and carbon neutral balance, closed water cycle and almost a cradle to cradle building material cycle. However, monitoring results shows the difficulty to maintain optimal thermal comfort during extreme summer and winter periods. Achieving the environmental zero impact objectives is not economically feasible without the subsidies from the federal and regional government. [less ▲]

Anthropogenic impact on CO2 levels was studied in the low-volume chamber connected with the low-profile corridor in Balcarka Cave, the show cave in Moravian Karst, during the period of limited ventilation. Modeling showed that the natural CO2 levels were controlled by the CO2 fluxes (up to ~ 3.14 × 10-2 mol s-1) from adjacent spaces. These fluxes changed with cave airflows and ventilation modes. Two main components of anthropogenic impact were recognized: (1) visitor breathing and (2) visitor movement. The CO2 input derived from individual visitor groups varied from 1.96 × 10-4 to 2.45 × 10-3 mol s-1, which was the significant part of the CO2 fluxes from adjacent spaces. The visitor movement induced the airflows up to 0.2 m3 s-1. They exceeded the natural airflows (up to 3.2 × 10-3 m3 s-1) by factor of more than 60. These airflows caused cave ventilation mode’s switching and, significant drop of CO2 fluxes/levels due to changed ventilation. The study therefore indicates that various anthropogenic influences in show cave can balance and neutralize each other, in dependence on cave morphology and seasonal conditions. [less ▲]

Introduction: Quantitative Risk assessment could be applied in industries as a tool to control and manage the safety of food products. Purpose: A contamination by Listeria monocytogenes of cheeses made from raw milk was reported by the Belgian food agency. This contamination was caused by the presence of an asymptomatic “shedder” goat in the herd. With field and laboratory collected data, a quantitative risk assessment model of the production chain was developed. Methods: A modular risk model was built to simulate the food production pathway covering the milking of goats until the final product for the customers. A dynamic square root model was used to predict the growth rate in relation with the temperature, the pH and the water activity along the production chain with predictive microbiology modules. Results: The shedder goat was identified from the herd and milk samples were taken from the two different parts of the mammary gland with 2.6 log cfu (colonies forming units) Listeria monocytogenes/ml for the right part and absence in 25 ml for the left part of the mammary gland. Numbering of Listeria monocytogenes was carried out on the final products with 3.6 log cfu/g in the fresh not ripened cheeses. The modular risk assessment shows a significant growth of Listeria monocytogenes during chilling and storage of the milk collected the day before the cheese production (increase of 0.6 log cfu/ml) and during adjunction of ferment and rennet to milk (increase of 0.8 log cfu/ml). The model confirms the results obtained in the final products. Significance: The modular risk model gives valuable informations to identify and to control critical steps in the food production chain of goat cheese made from raw milk. Only one shedder goat can cause a high risk to become ill for the consumers of contaminated products. [less ▲]
