Experimental testing equipment is built in order to identify material parameters of complex phenomenological constitutive laws. This equipment consists in a bi-axial test machine able to perform plane strain and simple shear tests separately or simultaneously and a Miyauchi simple shear test device; an optical extensometer is used to identify the strain field. The article focus on the validation of the results of this new equipment by comparing with results obtained by standard machines and/or by using FEM simulations of already identified materials. The first results show that the bi-axial machine performs the plane strain test optimally and some modifications are proposed in order to improve the results for the simple shear test. Miyauchi device shows a good performance and the experimental results are compared with a FEM simulation. [less ▲]

Recent theoretical and clinical contributions of elderly couple with alcoholic partner underlies the usefulness of pragmatic/interactive and semantic/symbolic approach of symptomatic situation. Particularly, alcohol-dependance is understood as related to developmental tasks, resources and bonds of life-cycle of elderly age. A psychotherapeutic process of elderly couple is narrated. This work is caractherized by the following phases: alcoholistic symptom control, individual and family story narration and renegociation and reshaping of couple spaces/times. Symptom gradual dissolution has permitted the relaunching of individual, couple and familial planning as a fundamental dimension for improving general quality life of elderly couple. [less ▲]

Background Low frequency (<0.1Hz) fluctuations originating from blood flow and oxygenation have been observed in the brain by different groups (Golanov et al. 1994; Biswal.et al. 1995). The goal of this study was to use BOLD fMRI to characterize coherent fluctuations in those low frequencies between spatially distant brain regions. Methods Thirteen right-handed subjects were studied using blocked-design BOLD fMRI at rest and as they performed sequential finger movements at a slow rate (~0.5 Hz) with their right hand. Serial acquisitions of EPI images were obtained at 3T using a single-shot 2D gradient-echo echo-planar imaging sequence. Data were processed and analyzed using standard procedures implemented in the statistical parametric mapping software (SPM2). Temporal profile of brain activity in 6 predefined regions (left S1M1, right S1M1, SMA, left thalamus, right cerebellum and CSF) were extracted on a subject-by-subject basis using the VOI tool in SPM2. After deconvolution (Gitelman et al. 2003), time series data representing movement and resting conditions were concatenated to create 2 within-condition time-series. After subtracting the mean over all epochs from each epoch, the (complex) coherency was calculated in the 5 lowest frequency bins with a frequency resolution of 1/17.5Hz (0, 0.05, 0.11, 0.17, 0.23 Hz). Real and imaginary parts of coherency, representing correlation and correlation of phase-shifted signals, respectively, were analyzed separately. Coherency was computed independently for each region pairs and each subject. Significance was defined as p<0.05 Bonferroni corrected for multiple comparisons. Results The main finding was the presence of coherent fluctuations in BOLD signal mainly in the lowest frequencies for (almost) all regions. The real part of coherency was equally pronounced during the movement and rest conditions. The only exception was a larger coherence during rest than during the task condition in the lowest frequencies between left and right S1M1. We could not find any significant imaginary part of coherency indicating that the time delays between dependent neural activations are negligible compared to the inverse frequencies under study. Partialling out the data in any of the regions did not have any significant impact on coherence map. Importantly, there was no evidence of coherent activity between any of the brain regions and CSF in any of the frequency bands. Discussion BOLD signal recorded during different behavioral steady-states showed very similar coherent fluctuations for all regions pairs studied mainly in the lowest frequencies. Those results are in good agreement with electrophysiological recordings in monkeys in which high coherence in band-limited power of local field potential signals have been reported at very low frequencies (<0.1Hz) (Leopold et al. 2003). In that study, coherence patterns were also highly similar under distinctly different behavioral states. Task-independent coherence in lower frequencies may be related to whole brain slow synchronous oscillations whose significance remains to be elucidated. References Golanov et al. (1994).

Pour lever l'apparente contradiction entre l'importance attribuée au système Bedaux et sa diffusion relativement limitée, il s'agit d'abord de mesurer avec précision son extension dans le tissu industriel belge des années '30 et de caractériser les entreprises utilisatrices, après avoir rappelé les principaux traits de ce système de gestion de la main-d'œuvre. La prise en compte des avantages que le système Bedaux offre aux entreprises dans différentes conjonctures, et des motifs de rejet ou d'acceptation conditionnelle par les travailleurs et leurs organisations, permettent de comprendre l'écho donné au système, au-delà de l'importance quantitative de son extension.

AIM: To describe the effect of introducing the CISOE-A framework for reporting cervical cytology results, including changes in repeat and referral advice in the Netherlands, on the efficacy of the screening programme. Changes in the distribution of cytological results, the detection rate of cervical intraepithelial neoplasia (CIN) lesions, and the detection rate of squamous cervical carcinoma are reported. METHODS: The results of all gynaecology cytological and histological examinations, as registered in the nationwide database for histopathology and cytopathology (PALGA) from 1990 to 2000, were retrieved from seven laboratories in the greater Amsterdam area. RESULTS: After the introduction of the CISOE-A classification, cytological results with equivocal diagnoses decreased significantly from 11.3% to 2.6%, without an increase in the percentages of moderate dyskaryosis or worse. During the study period, the detection rate of histologically diagnosed high grade CIN lesions increased significantly from 4.1 to 6.4/1000 smears, whereas there was no change in the detection rates of low grade lesions or invasive cervical cancer. CONCLUSIONS: The introduction of the new CISOE-A classification system resulted in a substantial decrease of equivocal results and repeat recommendations, without a decrease in the detection rate of high grade lesions, making the screening programme more efficacious.

This paper explains how the dynamic approach has been implemented in the computer software SAFIR in order to cope with temporary and local failures that occured in a step be step static analysis of structures subjected to fire.By means of this recently implemented dynamic algorithm, it’s now possible to simulate the complete failure mechanism, to predict the influence of a local failure on the global behaviour of the structure and to follow eventually the progressive collapse. Therefore the resistance time is now really determined whereas in the past many numerical failure corresponding to local failure were interpreted as resistance time of the whole structure. [less ▲]

The objective of this paper was to determine if changes in ventilation patterns could influence the outcome of respiratory function measurements performed with our impulse oscillometry system (IOS) in horses. In a first study, IOS tests were performed in vitro on six isolated equine lungs. Lung inflation levels were controlled by modifying depressurisation inside an artificial thorax and different ventilation patterns were imposed. In a second in vivo study, transient variations in breathing pattern were evaluated both with the IOS and a current reference technique (CRT) in five healthy mature horses after an intravenous (i.v.) injection of lobeline hydrochloride. In both studies, respiratory rate (RR, range: 7-42 breaths/min.) and tidal volume (V(T), range: 0.4-25 L) had minor or no influence on IOS parameters. The influence of lung inflation, most marked for resistance at 5 Hz (R(5 Hz)), was limited for the considered physiological range. In vivo, statistical models indicated that maximal changes in pleural pressure (Max Delta Ppl) and peak flows were the main determinants of the variability of the resistance (R(rs)) and the reactance (X(rs)) of the respiratory system. The fourfold increase in baseline Max Delta Ppl and peak flows obtained during hyperpnoea caused a significant increase in R(rs) at 5 and 10 Hz and a decrease in X(rs) at all frequencies. We conclude that IOS parameters are not influenced by tachypnoea, but will reflect alterations in respiratory mechanics caused by hyperpnoeic breathing [less ▲]
