In this case study, we study the generation of warning waves with prescribed characteristics in a mountain stream. We determine which dam release will generate the desired warning wave. We solve this inverse problem following a two-model approach. An analytical kinematic model is used for a preliminary design of the dam release and a detailed two-dimensional (2D) fully dynamic model is used to converge to the final solution. Although the presented case study is far from an idealized academic case, the analytical model performs well and, beyond its role for preliminary design, turns out to be of prime interest for both understanding and discussing the results of the detailed 2D model. The complex interactions between the release hydrograph, the geometry of the river and the friction formula are brought to light by the analytical model, which highlights the complementarity of both models and the usefulness of such a two-model approach.

Introduction: The lateral elbow tendinopathy is a common injury in tennis players and physical workers. The Patient- Rated Tennis Elbow Evaluation (PRTEE) Questionnaire was specifically designed to measure pain and functional limitations in patients with lateral epicondylitis. The aims were to adapt the PRTEE questionnaire into French (PRTEE-F) and to evaluate the reliability and validity of this translated version of the questionnaire . Methods: The PRTEE was translated and cross-culturally adapted into French according to international guidelines. To assess the reliability and validity of the PRTEE-F, 115 participants were asked twice to fill in the PRTEE-F, and once the DASH and the SF-36. Internal consistency (using Cronbach’s alpha), test-retest reliability (using intraclass correlation coefficient (ICC), standard error of measurement and minimal detectable change), and convergent and divergent validity (using the Spearman’s correlation coefficients respectively with the DASH and with some subscales of the SF-36) were assessed. Results: The PRTEE was translated into French without any problems. PRTEE-F showed a good test-retest reliability for the overall score (ICC 0.86) and for each item (ICC 0.8-0.96) and a high internal consistency (Cronbach’s alpha 1⁄4 0.98). The correlation analyses revealed high correlation coefficients between PRTEE-F and DASH (convergent validity) and, as expected, a low or moderate correlation with the divergent subscales of the SF-36 (discriminant validity). There was no floor or ceiling effect. Discussion and Conclusions: The PRTEE questionnaire was successfully cross-culturally adapted into French. The PRTEE-F is reliable and valid for evaluating French-speaking patients with lateral elbow tendinopathy. [less ▲]

In Belgium, river floods are among the most frequent natural disasters and they may have important consequences on travel demand. In order to better understand how the travel patterns vary, we propose to set up a large scale scenario based on MATSim for guarantying an accurate assessment of the impact of river floods on the transportation system. As inputs, the current agent-based model requires a base year population. A synthetic population with respective set of attributes is generated as a key input. Afterwards, agents are assigned activity chains through an activity-based generation process. Finally, the synthetic population and the transportation network are integrated into MATSim. Regarding data, households travel surveys, OD matrix of Belgium have been used to set up the demand. For simulating river floods effects, a steady-state inundation map has been integrated within MATSim. In the current study, five scenarios have been tested where critical links are associated various levels of service, i.e. 10%, 25%, 50%, 75% and 100% (base case scenario). They are systematically compared to the standard scenario to estimate the deviations in terms of traffic patterns and travel times. The results suggest that compared to the standard scenario, the average trip travel time increased by 16.36%, 44.44%, 126.77% and 144.44% with respect to scenarios 75%, 50%, 25% and 10% respectively. Also, the traffic flows have been re-distributed more uniformly across the transportation network. Roads with important traffic volumes are subjected to a decrease of activity on the contrary of roads with low traffic volumes. A very few studies have focused on how river floods affect transportation systems, this paper provided new insights in term of methodology and traffic patterns analysis under disruptions. [less ▲]

Summary Introduction: In developing countries, quality of prison life remains a challenge in public health. The present study aimed at determining the quality of life as perceived by inmates during their imprisonment at the Central Prison of Mbuji-Mayi, Democratic Republic of Congo. Materials and Methods: This cross-sectional study was carried out over a 3-month period (between December 2015 and February 2016) at the Central Prison of Mbuji-Mayi. Three hundred inmates participated to the survey. The World Health Organisation Quality of Life Scale (WHOQOL-BREF) was used to estimate health and problems affecting inmates’ everyday life. Results: Mean age of inmates was 33 ± 10 years (range: 18-70 years) and most of them were male (88.7%). The quality of life score they estimated was below 50, on the WHOQOL-BREF scale weighted over 100 points (average overall score: 26±7). When considering each WHOQOL-BREF domain, the lowest scores (0-100 normalised scale) were registered for: perception of physical health (24±11), psychological health (18±8), social relationship (39±15) and environmental relationships (24±8). Overall, inmates aged over 30 years old presented an average score slightly lower than younger inmates (25±6 vs. 27±7; p=0.005). Depending on the length of incarceration, the average score was lower for inmates imprisoned for more than 6 months compared to others (26±6 vs. 28 ± 8; p= 0.015). Correlations between domain scores were low but statistically significant; no correlation was highlighted between environment and mental health domains. Conclusion: Most inmates considered their quality of life as negative, regardless of the WHOQOL-BREF domain. Efforts to improve quality of life should remain a priority for political authorities.

Introduction: The Victorian Institute of Sport Assessment – Achilles tendinopathy questionnaire (VISA-A) evaluates the clinical severity of Achilles tendinopathy. The aim of this study was to translate the VISA-A into French and to study the reliability and validity of this French version, the VISA-AF.Method: The VISA-A was translated into French to produce the VISA-AF using a validated methodology in six steps. Thereafter, several psychometric properties of this French version such as test–retest reliability, internal consistency, construct validity and floor and ceiling effects were evaluated. Therefore, we recruited 116 subjects, distributed into 3 groups: pathological patients (n=31), at-risk athletes (n=63) and healthy people (n=22). Results: The final version of the VISA-AF was approved by an expert committee. On a scale ranging from 0 to 100, the average scores of the VISA-AF obtained were 59 (± 18) for the pathological group, 99 (± 1) for the healthy group and 94 (± 7) for the at-risk group. The VISA-AF shows excellent reliability, low correlations with the discriminant subscales of the SF-36 and moderate correlations with the convergent subscales of the SF-36. Conclusions: The French version of the VISA-A is equivalent to its original version and is a reliable and valid questionnaire for French- speaking patients with Achilles tendinopathy. [less ▲]

Episodic memories are typically composed of perceptual information derived from the external environment and representations of internal states (e.g., one’s thoughts during prior episodes). To date, however, research has mostly focused on the remembrance of external stimuli, such that little is known about how internal mentation is represented within episodic memory. In the present fMRI study, we examined the neural correlates of these two components of episodic memories using a novel method of cuing memories from photographs taken during real-life events. We found that, compared to corresponding semantic memory tasks, memories for internal thoughts and external elements were associated with activity in brain areas supporting episodic recollection. Most importantly, however, the two kinds of memories also showed differential activation in large-scale brain networks: the remembrance of external elements was associated with greater activity in the dorsal attention network, whereas memories of internal thoughts mainly recruited default network areas. These findings shed new light on the representation of internal and external aspects of prior experience within episodic memory. The default network may contribute to the reinstatement of thoughts experienced during past events, whereas the dorsal attention network may support the allocation of attention to visuo-spatial features within episodic memory representations.

Louise de Savoie occupies a singular place at the French royal court : neither queen nor queen-mother, but mother of the King, she nonetheless played a prominent role in the political and cultural affairs of France. Daughter of Philippe de Bresse, duc de Savoie, she was raised at the court of her aunt, Anne de France, and married in 1488 at age 11 to Charles d’Angoulême, head of a cadet branch of the royal house of Valois. At Cognac where the couple resided, she gave birth to her illustrious children, Marguerite in 1492, and François in 1494. After the sudden death of her husband in 1496, she was herself still too young to be appointed their official guardian. Obliged to share that responsibility with Louis d’Orléans who became king in 1498, the young widow nonetheless asserted her authority in their education. How she succeeded in establishing her place at court, while her son, at first a distant heir to the throne, rose to be king in 1515, can be viewed through her astute patronage of arts and letters. Keenly aware of the power of books and images, Louise multiplied commissions that would reinforce her own position and that of her family and entourage, striving to align herself with illustrious women, past and present. Identified with “Dame Prudence” as she overcame obstacles and rivals, Louise de Savoie’s tenacious devotion to her children culminated in power that was fully recognized in the appointment of « Madame » as Regent of France.

Preclinical studies suggest that free access to a running wheel can attenuate behavioural effects of addictive drugs such as psychomotor sensitization to cocaine in rodents. This phenomenon has an integral role in the process of drug addiction in craving and relapse (Steketee and Kalivas, 2011). Free wheel-running was recently shown to be efficacious at preventing the initiation or the long-term expression of psychomotor sensitization to cocaine in mice or rats (Diaz et al., 2013; Geuzaine and Tirelli, 2014). In the present study, we investigated the neuro-functional correlates of the protection against psychomotor sensitization to cocaine afforded by free wheel-running on dopaminergic neurotransmission, using microPET imaging with [18F]Fallypride, a Dopamine 2 receptor (D2R) antagonist. Sixty-four 28-day-old female C57BL/6J mice were randomly assigned to one of the two housing conditions, defined by the presence or the absence of a running wheel in the cage over a 6-week pre-testing period. Since mice from the two types of housing received either saline (controls) or cocaine (8 mg/kg, i.p.) during testing (9 once-daily sessions to establish sensitization plus 1 single session to test its expression), a basic 2x2 randomized blocks design was generated (2-way ANOVA and planned comparisons; n=10). Experimentation lasted 85 days, with a 42-day period of pre-testing and a 3-week interval preceding the test for long-term expression of sensitization (LTES). All mice underwent a microPET (Focus 120, Siemens) the day after the LTES. The microPET protocol consisted of a 60 min. dynamic acquisition after the injection of 10 MBq of [18F]Fallypride in the tail vein. Wheel-running strongly and significantly attenuated LTES (interaction) to cocaine (Cohen’s d=1.63; t(21)=3.75, p<.001) and cocaine-treated mice exhibited a clear-cut and significant increase (main effect) of the [18F]Fallypride BP (d=0.88, t(31)=2.45, p =.02). Wheel-running induced an overall moderate-sized decrease (main effect) of the [18F]Fallypride BP, but without achieving statistical significance (d=0.64, t(31)=1.79, p =.08). These findings suggest that LTES is associated with an increase of the [18F]Fallypride BP in the mouse striatum, probably reflecting an increase in postsynaptic D2R density in this region. Also, the protecting effect of free running on psychomotor sensitization goes together with a decrease in D2R density in the striatum of exercised mice. We intend to complement the present study with an identical experiment to reach a total number of 80 mice (n=20). This will confer to our study a sufficient power (80%) for the main effect of wheel-running exercise on [18F]Fallypride BP to be detected at an alpha-level of 5%. Finally, autoradiography studies, performed on the same mice with [18F]Fallypride, will strengthen our in vivo results. [less ▲]

The material study of La Famille Soler through non-invasive imaging, molecular, structural and elemental techniques, permitted a relevant re-examination of this singular blue period painting, which is considered as the earliest Picasso’s version of Le déjeuner sur l’herbe by E. Manet. On the one hand, it was concluded that the underlying landscape painted by Vidal in 1903 referred to Manet’s masterpiece. On the other hand, it was assumed that the cubist sketch undertaken by Picasso in 1912, prior to the current blue background, consists of an uncompleted transformation of Vidal’s landscape into synthetic cubism. Additionally, the main pigments associated to the underlying compositions were successfully identified. [less ▲]

In the eighteenth century, literary journals have set a specific relationship with their readers. By publishing letters from the public and by answering to their demands (or not), the journalists have established a readers’ community that share a common cultural universe. This article aims at analyzing the relationship between the antiphilosophe François-Xavier de Feller and the readership of his Journal historique et littéraire. The journalist, who wishes to fight against the philosophes and to spread his own radical ideas above all, has however taken his public’s capacity of reaction into account. This article will question the mechanisms of this relationship by considering the letters from the public to the editor but also Feller’s own addresses to his readership published in the journal. Even if he refuses the idea that every man is able to use his own critical reason, the journalist has been influenced by his readership but, more importantly, he has maintained in his public a new form of criticism, radically opposed to the ideas of Enlightenment.

Introduction: The femoropatellar syndrom is one of the most common knee problem observable. The Kujala Anterior Knee Pain Scale (AKPS) is a questionnaire used to examine the subjective symptoms, such as the functional limitations and the anterior knee pain. Objective: The aims of the study were to translate and cross-culturally adapt the AKPS questionnaire into French and to evaluate the reliability and validity of this translated version of the questionnaire (AKPS- F). Patients : 101 patients with femoropatellar syndrom. Methods: The translation and the inter-cultural adaptation of the questionnaire has been adopted through the international recommendations highlighting 6 different steps : initial translation, translations synthesis, translation back to the original language, committee of experts, test of the pre-final version and the approval from the expert’s committee. Indeed the French version obtained, the participants have filled twice the AKPS with an interval of 7 days, and the Short Form Health in order to evaluate the psychometric properties (the internal coherence, the test-retest fidelity and the built validity). Results:The AKPS shows a high level of fidelity in the test-retest with a score of 0.97. The French translation also has a high internal coherence score with 0.87. The Kujula shows a great correlation with a part of the converging sub-scales from the SF36. There is a low/average correlation noticeable with the diverging sub-scales. There is no floor/ceiling effect. Discussion and conclusions: This study shows that AKPS-F is reliable and valid for the French patients suffering from a femoropatellar syndrom and can therefore be used. [less ▲]
