The texture of resorcinol-formaldehyde gels, previously synthesized by Pekala et al. [1-6], but dried by freeze-drying was studied. The freeze-dried gels present a complex porous structure from nanometer to micrometer length-scale. Taking a standard freezing rate, we study in detail the influence of the molar ratio resorcinol/catalyst on the texture, This molar ratio is one of the parameters under consideration which can lead to a tailoring of the dried gel texture in order to develop adsorbents or catalyst supports of controlled porosity. Characterization methods include nitrogen adsorption-desorption (including the classical and the fractal interpretations), mercury porosimetry, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and small angle X-ray scattering (SAXS).

We demonstrate experimentally and theoretically that the dissipative state at high current densities of superconducting samples with a periodic array of holes consist of flux rivers resulting from a short range attractive interaction between vortices. This dynamically induced vortex-vortex attraction results from the migration of quasiparticles out of the vortex core. We have directly visualized the formation of vortex chains by scanning Hall microscopy after freezing the dynamic state by a field cooling procedure at constant bias current. Similar experiments carried out in a sample without holes show no hint of flux river formation. (C) 2010 Elsevier B.V. All rights reserved. [less ▲]

OBJECTIVES: ENT surgeons are facing an ever-increasing demand to demonstrate their efficacy. The 22-item Sino-Nasal Outcome Test (SNOT-22) is a fully validated and easy-to-use outcome measure in rhinology. Our goal was to translate and validate the SNOT-22 in a cohort of 422 French-speaking subjects. DESIGN, SETTING AND PARTICIPANTS: The French version of the SNOT-22 was obtained by forward and backward translations by 6 independent interpreters. Five experienced rhinologists compared the translations to each other and a group of 12 naive patients selected the most appropriate translation of each item. To evaluate this questionnaire, we conducted a prospective cohort study on 376 rhinological patients and 46 healthy volunteers in 3 University-affiliated teaching Hospitals. MAIN OUTCOME MEASURES: reproducibility (test-retest reliability), internal consistency, known group differences, responsiveness to treatment, validity and correlation to other clinical instruments (visual analogue scale, Nasal Obstruction Symptoms Evaluation score and Lund-Mackay score). RESULTS: The test-retest reliability coefficient was 0.78, indicating a good reliability when administering the instrument on two different occasions. The internal consistency was high with a Cronbach's alpha value of 0.93. Our questionnaire was able to detect differences between rhinological patients and control subjects (p<0.0001) and improved significantly after nose and sinus surgery (p<0.0001), indicating a good responsiveness. There was a relative correlation with visual analogue scale and NOSE score, but no correlation with Lund-Mackay score. CONCLUSION: The SNOT-22 is a reliable and valid tool to assess quality of life in French-speaking patients and correlates well with known indices of disease severity.

Thorell and Nyberg (2008) recently developed the Childhood Executive Functioning Inventory (CHEXI), a new rating instrument for executive functioning in day-to-day life that can be divided into four subscales: working memory, planning, inhibition, and regulation. By using an exploratory factor analysis on data from young Swedish children attending kindergarten, Thorell and Nyberg (2008) found a two-factor solution tapping working memory and inhibition. In the present study, we explored the psychometric characteristics of the French adaptation of the CHEXI. Ninety-five parents of 5- and 6-year-old children completed the CHEXI. Eighty-seven children from this sample were given clinical inhibition and working memory tasks. Confirmatory factor analyses confirmed the two-factor solution based on inhibition and working memory that was identified in the original study of Swedish children. Supplementary results indicated good internal and test-retest reliability for the entire scale, as well as for the two subscales identified. Correlation analyses showed no relationship between cognitive measures and the CHEXI subscales. Possible clinical applications for the CHEXI scales are discussed. [less ▲]

Impulsivity is an important and multifaceted psychological construct. Recently, Whiteside and Lynam (2001) have developed the UPPS Impulsive Behavior Scale that distinguishes four dimensions of impulsivity: Urgency, lack of Premeditation, lack of Perseverance, and Sensation seeking. In the present study, we investigated the psychometric properties of a French adaptation of the UPPS Impulsive Behavior Scale. Two hundred and thirty-four undergraduate students completed the UPPS Scale. Exploratory and confirmatory analyses revealed a four factors solution similar to that found in the original study. Also, the results indicated that there was good to very good internal reliability for the four subscales. [less ▲]

In 1998, the French Parliament enacted a law regarding the struggle against discrimination . In response to this legislation, the French Minister of Justice implemented a new judicial structure (the "Houses of Law") in areas which had been defined as "districts in difficulty" or "areas where the law is not applied anymore." The purpose of this structure was to provide advice to inner city inhabitants within these Houses of Law with the aim to reduce inequalities between the citizens who can hire private lawyers and the ones who cannot. First, this research examines the means by which the French Government implemented these affirmative action policies, which are an obstacle in the state's pursuit of the principle of equality; a fundamental precept of the French Republic . Instead of focusing on people, governmental policy targeted geographic areas, specifically inner city. Secondly, this research studies the work of private lawyers operating within the public sector judicial structures and asks whether these "Houses of Law" are equitable arrangements for all citizens due to their locational situation.

Background Manual handling of loads (MHL) is a widespread practice in the workplace and is the leading cause of work accidents. In particular, MHL is associated with a risk of low back injuries which can compromise staying at work and worker's career in the case of recurrence or chronicity. This communication aims to set forth the French occupational Guidelines for the management of the low back pain (LBP) risk among workers exposed to MHL, published in October 2013. Methods These Good Practice Guidelines were written according to the Clinical Practice Guidelines method proposed by the French National Authority for Health. They emanated from a synthesis of the literature by a multidisciplinary working party of 24 experts and were peer reviewed by a committee of 50 experts. These Guidelines are designed to define the components of an appropriate surveillance program for all workers exposed to MHL activities at the workplace and especially suffering from LBP and still at work, or suffering LBP and on sick leave. Results Because of the potential impact on workers’ fears and beliefs, the information provided by the various actors must be consistent, or even reassuring in relation to the prognosis of LBP. Among LBP workers, it is recommended to look for signs of severity or an underlying disease at the acute, subacute and chronic stages of LBP; to encourage continuation or resumption of physical activity; situate the current episode of LBP in the worker’s work history (recent changes of working conditions) and evaluate the impact of LBP on the worker’s job. In the case of persistent or recurrent LBP, it is recommended to evaluate biopsychosocial and socioeconomic risk factors likely to influence chronicity, prolonged incapacity and delay return to work. If workers are on prolonged and/or repeated sick leave for LBP, a pre-return-to-work visit is recommended to evaluate the pain and functional disability and their repercussions, as well as the main factors of prolonged work incapacity; encourage and help the worker to develop a return to work dynamic; identify the main difficulties related to work and possible job adjustments and evaluate the need to initiate a job staying at work approach. Conclusions Primary, secondary and tertiary prevention are necessary for the management of low back pain at work. [less ▲]
