The prototypes and software used to build these measuring instruments were evaluated and redesigned at the functional and didactic levels in order to offer a learning environment that respects in every way the competence approach and the integration between science and technology.

This dissertation focuses on the problem of designing rates in the utility sector. It is motivated by recent developments in the electricity industry, where renewable generation technologies and distributed energy resources are becoming increasingly relevant.

Both technologies disrupt the sector in unique ways. While renewables make grid operations more complex, and potentially more expensive, distributed energy resources enable consumers to interact two-ways with the grid. Both developments present challenges and opportunities for regulators, who must adapt their techniques for evaluating policies to the emerging technological conditions.

The first two chapters of this work make the case for updating existing techniques to evaluate tariff structures. They also propose new methods which are more appropriate given the prospective technological characteristics of the sector.

The first chapter constructs an analytic tool based on a model that captures the interaction between pricing and investment. In contrast to previous approaches, this technique allows consistently comparing portfolios of rates while enabling researchers to model with a significantly greater level of detail the supply side of the sector.

A key theoretical implication of the model that underlies this technique is that, by properly updating the portfolio of tariffs, a regulator could induce the welfare maximizing adoption of distributed energy resources and enrollment in rate structures. We develop an algorithm to find globally optimal solutions of this model, which is a nonlinear mathematical program.

The results of a computational experiment show that the performance of the algorithm dominates that of commercial nonlinear solvers. In addition, to illustrate the practical relevance of the method, we conduct a cost benefit analysis of implementing time-variant tariffs in two electricity systems, California and Denmark. Although portfolios with time-varying rates create value in both systems, these improvements differ enough to advise very different policies.

While in Denmark time-varying tariffs appear unattractive, they at least deserve further revision in California. This conclusion is beyond the reach of previous techniques to analyze rates, as they do not capture the interplay between an intermittent supply and a price-responsive demand. While useful, the method we develop in the first chapter has two important limitations.

One is the lack of transparency of the parameters that determine demand substitution patterns, and demand heterogeneity; the other is the narrow range of rate structures that could be studied with the technique.

Both limitations stem from taking as a primitive a demand function. Following an alternative path, in the second chapter we develop a technique based on a pricing model that has as a fundamental building block the consumer utility maximization problem. Because researchers do not have to limit themselves to problems with unique solutions, this approach significantly increases the flexibility of the model and, in particular, addresses the limitations of the technique we develop in the first chapter.

This gain in flexibility decreases the practicality of our method since the underlying model becomes a Bilevel Problem. To be able to handle realistic instances, we develop a decomposition method based on a non-linear variant of the Alternating Direction Method of Multipliers, which combines Conic and Mixed Integer Programming. A numerical experiment shows that the performance of the solution technique is robust to instance sizes and a wide combination of parameters.

We illustrate the relevance of the new method with another applied analysis of rate structures. Our results highlight the value of being able to model in detail distributed energy resources. They also show that ignoring transmission constraints can have meaningful impacts on the analysis of rate structures.

In addition, we conduct a distributional analysis, which portrays how our method permits regulators and policy makers to study impacts of a rate update on a heterogeneous population. While a switch in rates could have a positive impact on the aggregate of households, it could benefit some more than others, and even harm some customers.

Our technique permits to anticipate these impacts, letting regulators decide among rate structures with considerably more information than what would be available with alternative approaches. In the third chapter, we conduct an empirical analysis of rate structures in California, which is currently undergoing a rate reform.

To contribute to the ongoing regulatory debate about the future of rates, we analyze in depth a set of plausible tariff alternatives.

In our analysis, we focus on a scenario in which advanced metering infrastructure and home energy management systems are widely adopted. Our modeling approach allows us to capture a wide variety of temporal and spatial demand substitution patterns without the need of estimating a large number of parameters.

Abstract shortened by ProQuest. Caracterisation experimentale et numerique de la flamme de carburants synthetiques gazeux. The goal of this research is to characterize experimentally and numerically laminar flames of syngas fuels made of hydrogen H2carbon monoxide COand carbon dioxide CO2.

Thus, the present thesis is divided in three chapters, each one corresponding to a secondary objective. The observed constant flame temperature with the addition of CO, which has a higher adiabatic flame temperature, is mainly due to the increased heat loss through radiation by CO2. Concerning major species, the maximal measured H 2O concentration decreases with addition of CO to the fuel, while the central CO2 concentration increases, as expected.

The slow chemical reactions necessary to produce CO2 compared to the ones forming H2O could explain this difference. This model compares different combustion mechanisms and shows that a reduced kinetic mechanism reduces simulation times while conserving the results quality of more complex kinetic schemes.

The most important recommendation of this work is to include a NOx mechanism to the numerical model in order to eventually determine an optimal fuel. It would also be necessary to validate the model over a wide range for different parameters such as equivalence ratio, initial temperature and initial pressure. Changes in the energy and sodium content of main entr ées in US chain restaurants from to The food environment shapes individual diets, and as food options change, energy and sodium intake may also shift.

Understanding whether and how restaurant menus evolve in response to labeling laws and public health pressures could inform future efforts to improve the food environment. To track changes in the energy and sodium content of US chain restaurant main entr ées between spring when the Affordable Care Act was passed, which included a federal menu labeling requirement and spring Nutrition information was collected from top US chain restaurants' websites, comprising unique brands.

Descriptive statistics and regression analysis evaluated change across main entr ées overall and compared entr ées that were added, removed, and unchanged.

Tests of means and proportions were conducted for individual restaurant brands to see how many made significant changes. Separate analyses were conducted for children's menus. Mean energy and sodium did not change significantly overall, although mean sodium was 70 mg lower across all restaurants in added vs removed menu items at the 75th percentile.

Changes were specific to restaurant brands or service model: family-style restaurants reduced sodium among higher-sodium entr ées at the 75th percentile, but not on average, and entr ées still far exceeded recommended limits. Fast-food restaurants decreased mean energy in children's menu entr ées by 40 kcal. A few individual restaurant brands made significant changes in energy or sodium, but the vast majority did not, and not all changes were in the healthier direction. Among those brands that did change, there were slightly more brands that reduced energy and sodium compared with those that increased it.

Industry marketing and pledges may create a misleading perception that restaurant menus are becoming substantially healthier, but both healthy and unhealthy menu changes can occur simultaneously. Our study found no meaningful changes overall across a 1-year time. Contexts of occurrence of child malnutrition in the district of Villaguay, Entre Ríos, Argentina. A multivariate analysis.

The analysis of nutritional status is anthropologically important to address the complex interaction of biological, social, political, economic and cultural factors. To deepen the knowledge about contexts of occurrence of child malnutrition, we analyzed nutritional status in relation to socio-environmental conditions of residence in children between three and six years from Villaguay, Entre Ríos, Argentina.

We performed a cross-sectional study of 1, school children of both sexes. Anthropometric data showed 1. Isto significa que o transdutor deve ser ressonante na mesma freqüência que a antena aproximadamente Hz.

Neste trabalho foi desenvolvida uma geometria para a estrutura mecânica do trandutor. Half-size me? How calorie and price information influence ordering on restaurant menus with both half and full entr ée portion sizes. Many restaurants are increasingly required to display calorie information on their menus. We present a study examining how consumers' food choices are affected by the presence of calorie information on restaurant menus.

However, unlike prior research on this topic, we focus on the effect of calorie information on food choices made from a menu that contains both full size portions and half size portions of entr ées. This different focus is important because many restaurants increasingly provide more than one portion size option per entr ée. Additionally, we examine whether the impact of calorie information differs depending on whether full portions are cheaper per unit than half portions non-linear pricing or whether they have a similar per unit price linear pricing.

We find that when linear pricing is used, calorie information leads people to order fewer calories. This decrease occurs as people switch from unhealthy full sized portions to healthy full sized portions, not to unhealthy half sized portions. In contrast, when non-linear pricing is used, calorie information has no impact on calories selected. Considering the impact of calorie information on consumers' choices from menus with more than one entr ée portion size option is increasingly important given restaurant and legislative trends, and the present research demonstrates that calorie information and pricing scheme may interact to affect choices from such menus.

Elle porte plus particulièrement sur la dimension qualitative de la sensation de douleur. Design Energy intake, bite size, and comments about portion size were evaluated among 30 children at 2 series of lunches in which either an age-appropriate portion or a large portion of an entr ée was served.

These increases were seen even though observational data indicated that the children were largely unaware of changes in portion size. Greater responsiveness to portion size was associated with higher levels of overeating. Children with satiety deficits may be most susceptible to large portions. Cohen, Juliana F. Background There are currently no national standards for school lunch period lengths and little is known about the association between the amount of time students have to eat and school food selection and consumption.

Relation entre les caractéristiques des table-bancs et les mesures anthropométriques des écoliers au Benin. Introduction Le mobilier scolaire et la posture assise en classe sont souvent impliqués dans l'apparition des douleurs rachidiennes, influant de fait sur la qualité des tâches réalisées par les apprenants.

Aucune étude n'a encore vérifié le degré d'adéquation entre les caractéristiques du mobilier et celles des écoliers au Bénin. L'objectif de cette étude transversale est donc de déterminer la relation entre les dimensions des table-bancs utilisées en classe et les mesures anthropométriques des écoliers au Bénin.

Methods Elle a été réalisée avec un échantillon probabiliste de écoliers, âgés de 4 à 17 ans. Les mesures anthropométriques des écoliers et les mensurations relatives aux longueurs, largeurs et hauteurs des table-bancs ont été mesurées, puis intégrées aux équations proposées dans la littérature.

Les pourcentages des valeurs situées hors des limitesacceptables, dérivées de l'application des équations ont été calculés. Results La largeur et la hauteur des table-bancs utilisées par les écoliers étaient plus élevées p entre la largeur du banc et la longueur fesse-poplité, puis entre la hauteur de la table et la distance coude-bancdes écoliers.

Introduction Des différences épidémiologiques, étiologique voire pronostique des hémorragies digestives hautes HDH entre les deux sexes opposés ont été cité par différentes études.

Méthodes Nous avons essayé de déceler ces différences à travers une analyse rétrospective nichée sur une étude prospective sur les hémorragies digestives hautes ayant inclus patients. Les étiologies de l'HDH étaient différentes entre les deux sexes. Conclusion L'étude trouve un profil épidémiologique, clinique et étiologique différent selon le sexe des patients.

Influence des interactions entre écrans de soutènement sur le calcul de la butée. La mobilisation de la butée devant un écran implique un volume de sol important, sur une distance plus grande que la fiche et qui dépend des paramètres du calcul.

L'article passe en revue les méthodes de calcul utilisées pour évaluer la butée, en insistant sur la distance nécessaire au libre développement du mécanisme de butée. Il évalue ensuite de différentes façons l'effet de l'interaction entre deux écrans 60 ans perdre son ventre face à face de part et d'autre d'une excavation.

La méthode recommandée pour calculer la butée mobilisable consiste à faire un calcul en éléments finis avec des valeurs réduites des paramètres de résistance au cisaillement dans la zone où se développera la butée.

Cette démarche permet de déterminer des facteurs correctifs à appliquer au calcul de la butée d'un écran isolé en fonction du rapport de la distance entre écrans à leur fiche. There are currently no national standards for school lunch period length and little is known about the association between the amount of time students have to eat and school food selection and consumption.

Our aim was to examine plate-waste measurements from students in the control arm of the Modifying Eating and Lifestyles at School study to school year to determine the association between amount of time to eat and school meal selection and consumption.

We used a prospective study design using up to six repeated measures among students during the school year. One thousand and one students in grades 3 to 8 attending six participating elementary and middle schools in an urban, low-income school district where lunch period lengths varied from 20 to 30 minutes were included.

School food selection and consumption were comment perdre du ventre pour une femme de 50 ans originale using plate-waste methodology. Logistic regression and mixed-model analysis of variance was used to examine food selection and consumption.

Among those who selected a meal component, students with entr ée P entr ée, milk, and vegetable consumption compared with students who had more time to eat. School policies that encourage lunches with at least 25 minutes of seated time might reduce food waste and improve dietary intake. Published by Elsevier Inc.

Energy, saturated fat, and sodium were lower in entr ées at chain restaurants at 18 months compared with 6 months following the implementation of mandatory menu labeling regulation in King County, Washington. Policies on menu labeling have been proposed as a method to improve the food environment. However, there is little information on the nutrient content of chain restaurant menu items and changes over time. To evaluate the energy, saturated fat, and sodium content of entr ées 6 and 18 months post-implementation of restaurant menu labeling in King County of Washington State for items that were on the menu at both time periods, and across all items at 6 and 18 months and to compare energy content to recommendations provided by the Dietary Guidelines for Americans.

One establishment per chain was audited at each time period. The content of entr ées at 18 months was compared with one-third assuming three meals per day of the nutrient intake recommendations for adults provided by the Dietary Guidelines for Americans. The audit included 37 eligible chains of 92 regulated chains. Energy contents were lower all chainssit downand quick service ; paired t tests P entr ées that were on the menu at both time periods.

There was a significant trend across quartiles for a decrease in energy, saturated fat, and sodium for all entr ées at sit-down chains only. Modest improvements in the nutrient content of sit-down and quick-service restaurant entr ées occurred but overall levels for energy, saturated fat, and sodium are excessive.

Um total de 5. This system is one of the most important groundwater reservoirs; it is shared by four neighboring countries covering an area larger than one million square kilometers. The geological units closely related to the Guaraní Aquifer are the Piramboia and Botucatu Formations that consist of Triassic-Jurassic aeolian, fluvial and lacustrine sandstones, and the Serra Geral basalts with clastic intercalations.

Serra Geral, an effusive Cretaceous complex, covers the sandstones and provides a high degree of confinement to the system. This paper presents the interpretation of magnetotelluric MT data collected during in Entre Ríos Province, Argentina. These data, recorded in three profiles, mainly provide the depth to the crystalline basement, determinant for the presence of aquifer-related sediments.

Models showed that the discrimination of the basalts strongly depends on local electrical characteristics. Model information is quite consistent with the information from oil and thermal wells located close to the profiles. Entre Familia: Reflejos de Salud was a successful family-based randomized controlled trial designed to improve dietary behaviors and intake among U.

The novel intervention design merged a community health worker promotora model with an entertainment-education component. This process evaluation examined intervention implementation and assessed relationships between implementation factors and dietary change. Participants included mothers randomized to an intervention condition. Process evaluation measures were obtained from participant interviews and promotora notes and included fidelity, dose delivered i.

Outcome variables included changes in vegetable intake and the use of behavioral strategies to increase dietary fiber and decrease dietary fat intake. Participant satisfaction was high, and fidelity was achieved; Trends suggested that keeping families in the prescribed intervention timeline and obtaining support from other social network members through sharing of program materials may improve changes.

Study findings elucidate the relationship between specific intervention processes and dietary changes.

On estime que sur les 3,7 millions des travailleurs au Quebec, plus de sont exposes quotidiennement a des niveaux de bruits pouvant causer des lesions de l'appareil auditif.

Lorsqu'il n'est pas possible de diminuer le niveau de bruit environnant, en modifiant les sources de bruits, ou en limitant la propagation du son, le port de protecteurs auditifs individualises, telles que les coquilles, demeure l'ultime solution. Bien que vue comme une solution a court terme, elle est communement employee, du fait de son caractere peu dispendieux, de sa facilite d'implantation et de son adaptabilite a la plupart des operations en environnement bruyant.

Cependant les protecteurs auditifs peuvent etre a la fois inadaptes aux travailleurs et a leur environnement et inconfortables ce qui limite leur temps de port, reduisant leur protection effective. Afin de palier a ces difficultes, un projet de recherche sur la protection auditive intitule : " Developpement d'outils et de methodes pour ameliorer et mieux evaluer la protection auditive individuelle des travailleur ", a ete mis sur pied enassociant l'Ecole de technologie superieure ETS et l'Institut de recherche Robert-Sauve en sante et en securite du travail IRSST.

S'inscrivant dans ce programme de recherche, le present travail de doctorat s'interesse specifiquement a la protection auditive au moyen de protecteurs auditifs " passifs " de type coquille, dont l'usage presente trois problematiques specifiques presentees dans les paragraphes suivants.

La premiere problematique specifique concerne l'inconfort cause par exemple par la peeling visage essonne 2014 statique induite par la force de serrage de l'arceau, qui peut reduire le temps de port recommande pour limiter l'exposition au bruit.

Il convient alors de pouvoir donner a l'utilisateur un protecteur confortable, adapte a son environnement de travail et a son activite. La seconde problematique specifique est l'evaluation de la protection reelle apportee par le protecteur. La methode des seuils auditifs REAT Real Ear Attenuation Threshold aussi vu comme un "golden standard" est utilise pour quantifier la reduction du bruit mais surestime generalement la performance des protecteurs. Les techniques de mesure terrains, telles que la F-MIRE Field Measurement in Real Ear peuvent etre a l'avenir de meilleurs outils pour evaluer l'attenuation individuelle.

Si ces techniques existent pour des bouchons d'oreilles, elles doivent etre adaptees et ameliorees pour le cas des coquilles, en determinant l'emplacement optimal des capteurs acoustiques et les facteurs de compensation individuels qui lient la mesure microphonique a la mesure qui aurait ete prise au tympan.

La troisieme problematique specifique est l'optimisation de l'attenuation des coquilles pour les adapter a l'individu et a son environnement de travail. La piste des outils predictifs a ete tres peu etudiee jusqu'a present et meriterait d'etre approfondie. L'utilisation du prototypage virtuel, permettrait a la fois d'optimiser le design avant production, d'accelerer la phase de developpement produit et d'en reduire les couts.

L'objectif general de cette these est de repondre a ces differentes problematiques par le developpement d'un modele de l'attenuation sonore d'un protecteur auditif de type coquille. A cause de la complexite de la geometrie de ces protecteurs, la methode principale de modelisation retenue a priori est la methode des elements finis FEM. Pour atteindre cet objectif general, trois objectifs specifiques ont ete etablis et sont presentes dans les trois paragraphes suivants.

The concept of "Cosmography" is in disuse since the 80s of the last century, but the astronomical themes previously discussed in the school subjects of Geography and Cosmography remain in current textbooks.

The use of term "Cosmography" was rescued in this research, and the study of its re-signification prompted the appearance of the term Geographic Cosmography. The Geographic Cosmography is a field of studies of the Geography, whose set of knowledge and skills is predominantly scholar.

It studies the interface between terrestrial and celestial knowledge, and assigns a geographic significance to them. It examines human and natural relationships with Sidereal Space and its consequences for society and nature.

Analisa as relações humanas e naturais com o Espaço Sideral e suas consequências para a sociedade e a natureza. Etude des phenomenes chimiques au contact entre le bloc cathodique et la barre collectrice d'une cellule d'electrolyse d'aluminium. La production d'aluminium est une industrie importante au Québec. Les propriétés de ce métal le vouent à de multiples usages présents et futurs dans le cadre d'une économie moderne durable.

Toutefois, le procédé Hall-Héroult est très énergivore et des progrès demeurent donc nécessaires pour en diminuer les coûts financiers et environnementaux. Parmi les améliorations envisageables de la cellule d'électrolyse se trouve le contact entre la cathode et la barre collectrice, qui doit offrir une faible résistivité au passage du courant électrique.

En cours d'opération de la cellule, ce contact a tendance à se dégrader, générant des pertes énergétiques significatives. Le but du présent projet était donc d'étudier les phénomènes chimiques se produisant au contact bloc-barre de la cellule d'électrolyse Hall-Héroult.

En premier lieu, un aspect crucial à considérer est la pénétration du bain électrolytique dans la cathode, car des composés de bain atteignent éventuellement la barre collectrice et peuvent y réagir. A cet effet, une méthode novatrice a été développée afin d'étudier les cathodes et la pénétration du bain dans celles-ci à l'aide de la microtomographie à rayons X.

Cette méthode rapide et efficace s'est avérée fort utile dans le projet et a un potentiel important pour l'étude future des cathodes et des phénomènes qui s'y produisent. Ensuite, une cellule d'électrolyse rectangulaire à petite échelle a été développée. Plusieurs phénomènes observés 'en industrie sur des autopsies de cellules post-opération et rapportés dans la littérature ont été reproduis avec succès à l'aide de cette cellule expérimentale.

Puis, des tests sans électrolyse, ciblant l'effet du bain électrolytique sur l'acier, ont aussi été conçus et complétés afin de s.

Le transfert de connaissances entre les mathematiques et les sciences. Une etude exploratoire aupres d'eleves de 4e secondaire.

Au moment ou dans plusieurs pays on travaille a refondre les programmes d'etudes, tant au primaire qu'au secondaire, l'interet pour le transfert renait. Un des concepts fondamentaux en apprentissage consiste en l'habilete a reutiliser de facon consciente et efficace un acquis d'une situation a une autre situation. Cette recherche emane de preoccupations professionnelles au moment ou le chercheur etait enseignant au secondaire.

Au cours de ces annees, il lui a ete possible de constater que plusieurs eleves percevaient difficilement les liens presents entre les disciplines mathematiques et scientifiques. Des travaux en psychologie cognitive et plus particulierement selon une perspective du traitement de l'information ont servi de cadre de reference pour evaluer et analyser les capacites de transfert aupres d'eleves de 4e secondaire. Ce cadre de reference permet de formuler le principal objectif qui est de mieux comprendre le processus de transfert chez des eleves en situation de resolution de problemes scientifiques.

Cette these s'interesse donc au transfert en tant que phenomene important du processus d'apprentissage au sens de l'integration. La methode de recherche choisie, de nature qualitative, est principalement axee sur l'evaluation de la capacite a transferer des connaissances lors d'une epreuve et d'un entretien. Pour evaluer ce potentiel de transfert, nous avons elabore deux outils: une epreuve en mathematiques et en sciences et un guide d'entretien.

Pour la passation de l'epreuve, le chercheur a pu compter sur la collaboration de sujets provenant de deux ecoles. L'entretien complete la prise de donnees avec 13 sujets ayant accepte de poursuivre l'etude. Les donnees recueillies par ces instruments font ensuite l'objet d'une analyse de contenu.

L'hypothese d'un mecanisme lie a la proximite d'un etat antiferromagnetique est privilegiee. Une etape importante dans la resolution de cette problematique est l'identification de la symetrie du parametre d'ordre. D'apres de nombreux travaux sur les systemes fortement correles, la sonde ultrasonore, de par sa sensibilite aux excitations de quasiparticule a basse temperature, est consideree comme particulierement adaptee a l'etude de cette propriete. Cependant, son emploi necessite l'utilisation d'un compose metallique a basse temperature et completement supraconducteur.

En effet, il est situe loin de la transition du premier ordre de Mott et est completement supraconducteur.

De facon surprenante, ce systeme semble se coupler fortement avec le reseau ce qui augmente significativement la sensibilite de cette sonde aux proprietes du gaz electronique. Cependant, des difficultes techniques importantes, liees a la nature intrinseque de ce materiau, doivent etre surmontees pour proceder a des mesures suivant differentes polarisations. La presente etude a profondement modifie notre comprehension de ce systeme.

En effet, ces mesures ont permis de constater que le kappa-ET2Cu[N CN 2]Br est un compose qui est situe en bordure de la zone de coexistence entre la supraconductivite et le magnetisme, ce qui constitue un resultat totalement inattendu.

Etude experimentale et optimisation d'un systeme hybride hydraulique pour camions a ordures et amelioration des performances par raffinement de sa logique de controle. The aim of this thesis is to demonstrate experimentally the operation of a hydraulic hybrid system specifically dedicated to the application of refuse trucks in addition to proposing solutions to improve its control strategy.

The developed hybrid system recovers the vehicle's kinetic energy during braking. A variable displacement hydraulic motor then uses the energy stored in a hydraulic accumulator to assist the internal combustion engine ICE at suitable times. The particular aspect of this system is that assistance to the ICE can occur when it operates at idle and drives the auxiliary hydraulic equipment of the refuse truck.

Essentially, the control strategy initially developed maximizes the recovery of braking energy and uses that energy to minimize the solicitation of the ICE at idle. The experimental results obtained with two prototypes tested in real operating conditions show that the hybrid system can recover a significant portion of braking energy.

In addition, the results show that it is possible to reduce the load on the ICE during idle with the application of an assisting torque. However, the advantage of assisting the ICE in specific areas of the operating range is slim since the ICE's gross efficiency varies only slightly depending on conditions of operation. This is confirmed by the optimization of the control logic using deterministic dynamic programming. Therefore, since the efforts that would be required to regime anti cholesterol viande usa the ideal behavior in real time are significant for a relatively small and uncertain gain, the initial control logic is considered near optimal.

Finally, this thesis proposes an improved version of the torque assisting hybrid system that could shut down the ICE when the vehicle is stopped while maintaining functional the auxiliary hydraulic equipment. The simulation of a basic control strategy shows that such pressure management may be feasible in real time and that the potential gain in fuel savings is achievable.

Evaluation experimentale de l'efficacite des gants de protection contre les nanoparticules de dioxyde de titane dans des conditions de travail. Manufactured titanium dioxide nanoparticles nTiO2 enter into the formulation of several commercial products including cosmetics, paints, varnishes or food. An increasing number of people will be exposed to nanoparticles NPin particular, scientists during their research and workers in companies.

As such, they are an emerging source of hazard. Indeed, an increasing number of studies are warning against their likely harmful effects on health. Furthermore some studies have shown that the skin is not an impervious membrane to the NP and that NP penetration is possible when the skin is injured by abrasion, after repeated flexions or even intact. Therefore, dermal protection will be necessary in order to thoroughly protect NP users. Based upon the precautionary principle, gloves should be used as protection against chemicals.

However, to the best of our knowledge, no study on their resistance towards NP has been conducted. In this study, the performance of protective gloves was evaluated with respect to nTiO2 solutions and powders, under conditions simulating occupational use. Mechanical deformations, simulating those produced by hand flexing, were applied to nitrile and butyl rubber and latex samples that were in contact with nTiO2 in water, in propylene glycol or in powder form.

Following these results, the physicochemical and mechanical phenomena that facilitate the penetration of nTiO2 were identified and studied. It was shown that mechanical deformations caused both damage to the sample surface but also a change in the degree of crystallinity of the glove material.

Strain energy was also measured. It decreased significantly in presence and absence of nTiO2, indicating a weakening of the polymer chains. A qualitative study showed that repetitive deformations also lead to a decrease in the size of the agglomerates that were contained in the nTiO2 powder.

Glove materials that were in contact with colloidal solutions produced a swelling phenomenon. Finally, measurements of the elongation of glove samples immersed in colloidal solutions were used to determine diffusion coefficients across the materials. The transport of the nanoparticles was driven by that of the carrier liquid water or propylene glycol.

Given the carrier solutions and nanoparticles could be transported through the gloves, exposure to skin could occur. Volume 2. Legge, H Jones and B. Journal of Heat. L'effet Doppler et le décalage vers le rouge en mécanique rationnelle: applications et verifications experimentales. Shifts z and z' toward the red of the galaxy NGC for a beam of 21 cm, z measured in radioastronomy with a frequency meter and z' measured in optics with a spectrograph, not being equal, it follows that the speed of light from a galaxy c ' is not equal to that of a galaxy c which is measured on earth from stationary source.

The Doppler empirical formula cannot be explained in classical mechanics since it is in contradiction with it. If we consider the universe represented on a three-dimensional space Hnon-Euclidian, with Euclidian connection plunged in a Riemannine four-dimension space Ea certain universal time, like that of an astronomer, can be defined and its course calculated in relation to this time: it will necessarily be confounded with the atomic clock time, but c ' not equal c and z' not equal z: the Doppler formula is not accurate.

However, c ' and c as well as z' and z are so close in all the experiments carried out on earth, even when an artificial satellite is used, that the errors made in using the Doppler formula are clearly inferior to experimental errors. Consequences experimentales des effets des fluctuations du vide sur la fluorescence parametrique et la generation du second harmonique en milieu confine.

Les fluctuations du vide, qui consistent en l'apparition momentanee de particules, ce qui est permit par le principe d'incertitude de Heisenberg, joue un role primordial dans les processus photoniques, en particulier les processus non-lineaires.

Par la manipulation de ces fluctuations du vide a l'aide de confinement optique, on retrouve deux phenomenes particuliers : l'intensification de la fluorescence parametrique Walker, et l'inhibition de la generation du second harmonique Collette, Dans ce travail, on presente les resultats dans le cas classique ; c'est-a-dire sans fluctuations du vide et confinement.

Par la suite, on presente les effets des fluctuations du vide et du confinement, ce qui mene aux deux effets mentionnes. Dans le cas de la fluorescence parametrique, le bruit quantique sur le champ interne et externe est calcule, le role du desaccord de phase dans le modele est expose et une generalisation tridimensionnelle est etudiee afin de generaliser la conception du modele d'un cas unidimensionnel a un cas tridimensionnel planaire.

Dans le cas de la generation du second harmonique, les difficultes d'un modele purement tridimensionnel sont exposees et ensuite le cas limite planaire est etudie. This article examines an important new manuscript discovery: a set of lectures delivered at the Society of Apothecaries in by four members of the Society.

No evidence of the intellectual and methodological assumptions of the apothecaries in this period has previously been known; the article contextualizes the lectures, and identifies the authors-a prominent group of apothecaries centered on the controversial John Buggs and the botanist Thomas Johnson.

It then proceeds to discuss the contents of the lectures, which consist, to a remarkable extent, of reflections on the nature of physic and pharmacy inspired by the works of sixteenth- and seventeenth-century medical humanists.

The apothecaries used the resources of medical humanism to raise the status of pharmacy comment maigrir de partout rapidement wow a medical discipline, and to argue for the proficiency of the apothecary as a fully fledged physician.

Moreover, they emphasized the role of operative arts and used the rhetoric of "experiment" and "experience" in ways that might seem, on first impression, to foreshadow the "new science" that would soon emerge in England. As such, the lectures allow us to make not only some major revisions to existing accounts of the apothecary-physician relationship and the intellectual assumptions behind it, but also to some prominent recent literature in the social history of science and the history of the concept of "experimental philosophy.

They are even supposed to play a major role in the formation of structures according to the standard hierarchical cosmological model.

Gravitational interactions, tidal forces and following mergers shape the morphology of galaxies, and leave vestiges which can survive for a few Gyr. They consist of stellar shells, streams, tails and plumes which emit a diffuse and extended optical light. Several deep imaging projects use telescopes of all sizes to try to detect this light.

We detail here what the census of collisional debris can tel us about the past history of galaxies and about the models and simulations supposedly accounting for it.

Pollution Atmosphérique et Santé: Corrélation ou Causalité? De nombreuses études épidémiologiques ont observé dans des contextes différents une faible relation à court terme entre les particules et la mortalité cardio-pulmonaire, même quand les normes de qualité de l'air n'étaient pas dépassées.

La causalité de cette relation est un enjeu de santé publique en raison de l'importance de la population exposée. Notre objectif est de faire l'inventaire critique des arguments utilisés dans 15 revues de la littérature publiées.

Nous expliquons l'importance de distinguer la validité de la causalité et analysons de façon systématique les différents critères de jugement dans le contexte des études écologiques temporelles. Notre conclusion est que la relation observée est valide et que la plupart des critères de causalité sont respectés.

Diminuer le niveau d'exposition des populations aux particules est souhaitable. En Europe, en agissant à la source, notamment sur les émissions Diesel, on diminuera aussi d'autres polluants qui peuvent jouer un rôle sanitaire.

Aux États-Unis, la situation est plus complexe car les particules sont surtout secondaires. Il est également indispensable de poursuivre les recherches pour mieux connaître les déterminants des expositions globales des individus et mieux comprendre le rôle toxique des différents facteurs physico-chimiques des particules.

Objetivo El objetivo de este estudio es demostrar la distinción entre engagement y trabajolismo, estudiando su relación con la calidad del sueño y el desempeño laboral. Método Un total de enfermeras de 3 hospitales de Japón fueron entrevistadas mediante un cuestionario autoadministrado que incluía la escala Utrecht UWES, Utrecht Work Engagement Scalela Escala de Adicción al Trabajo Holandesa DUWAS, Dutch Workaholism Scalepreguntas sobre la calidad del sueño 7 ítems con respecto a 1 dificultad para conciliar el sueño, 2 dificultad para mantener el sueño, 3 despertar temprano por la mañana, 4 dormirse o tomar siestas durante el día, 5 somnolencia diurna excesiva en el trabajo, 6 dificultad para despertarse por la mañana, y 7 despertar cansado en la mañana, y el Cuestionario sobre Salud y Desempeño CSD de la Organización Mundial de la Salud.

Resultados Los modelos de ecuaciones estructurales demostraron que el engagement se relaciona positivamente con la calidad del sueño y el rendimiento laboral, mientras que el trabajolismo tiene una relación negativa con la calidad del sueño y el desempeño laboral.

Conclusión Los resultados indican que el engagement y el trabajolismo son conceptualmente diferentes. El primero tiene una connotación positiva, mientras que el segundo se asocia de manera negativa al bienestar buena calidad del sueño y buen rendimiento en el trabajo.

Estudio de la influencia de la refrigeracion con aire de forma natural e inducida en el comportamiento de instalaciones fotovoltaicas. The presented research provides a deep knowledge of how they work as well as information and results for an improvement in future designs of building integrated photovoltaic systems.

Este estudio se centra en analizar la influencia negativa de la temperatura en la produccion electrica de paneles fotovoltaicos al estar emplazados sobre cubierta de acero, como sucede en naves industriales y sobre un invernadero. Se estudian diferentes configuraciones que permitan refrigerar los paneles, reduciendo su temperatura y mejorar su rendimiento. Para abordar este problema, se han construido dos instalaciones experimentalesfieles a plantas solares en funcionamiento.

Una instalacion engloba dos paneles fotovoltaicos sobre estructura fija al suelo. Uno de los paneles esta integrado sobre una superficie paralela y metalica.

Entre ambas superficies existe un espacio que posibilita circular aire, permitiendo refrigerar el panel por conveccion natural, o conveccion forzada impulsando el aire con un ventilador. El otro panel, libre por su cara posterior y se ha considerado de referencia. Se ha estudiado el comportamiento del panel integrado sobre cubierta para diferentes secciones de aire y velocidades inducidas, comparandolo con el panel de referencia. Se ha desarrollado un modelo experimental que nos permite determinar la temperatura del panel en funcion de las variables que influyen en su refrigeracion.

Adicionalmente, se han analizado los datos de una planta solar en funcionamiento, con paneles de igual caracteristicas, obteniendo correlaciones entre la temperatura del panel y las variables electricas y comparandolos con las obtenidas en la instalacion experimental.

La segunda instalacion experimental reproduce parte de una instalacion solar sobre un invernadero, formada por cuatro paneles fotovoltaicos colocados sobre el plastico del invernadero, existiendo un canal divergente entre ambas superficies. Se estudia la. Le rôle modérateur du soutien parental est confirmé dans la relation entre la victimisation homophobe et la détresse psychologique.

The shock waves Droduced by condenser discharge in a gas tube were investigated. The study was limited to wave velocities less than five times the speed of sound, propagated in gas at low pressure several mm Hg.

A method was designed and perfected for the detection of the shock waves that are insufficiently rapid to produce gas ionization. This method consisted of the creation of an autonomous plasma, before the arrival of the wave, which was then modified by the wave passage. The qualitative study of the modifications produced on the wave passage showed the remarkable correlation existing between the results obtained by the two methods. The experimental results on the propagation laws for shock waves in a low-diameter tube agreed with theory.

Los resultados del estudio reflejaron las concepciones erroneas de los estudiantes sobre la naturaleza de las ciencias y las pseudociencias. Con respecto a la demarcacion entre ciencia y pseudociencia, el criterio imperante entre los universitarios es el de la verificabilidad, considerando la aplicacion del metodo cientifico como el metodo para demostrar la veracidad de las teorias cientificas.

Las creencias y practicas pseudocientificas no son muy frecuentes entre los universitarios. Estos atribuyen las mismas a la prevalencia de elementos supersticiosos y al engano a que es sometida la poblacion. Modelo empirico integral de una plantacion de Eucalyptus grandis en Concordia, Entre Rios.

Kindergarteners' entr ée intake increases when served a larger entr ée portion in school lunch: a quasi-experiment. The influence of portion size on children's intake and self-regulation of food has gained attention; however, few studies have examined portion sizes in school lunch. This study investigated kindergarteners' intake when they were given different entr ée portion sizes from the lunch menu. Plate waste was used as a proxy to measure intake. A standardized lunch of chicken nuggets, rice, green beans, applesauce, and milk was served every Tuesday for 5 consecutive weeks at a Kinder Center.

All menu items and the self-selection of 2, 3, or 4 nuggets were served the first week as a pilot. In the second and fourth weeks, trained servers preportioned kindergarteners' plates with 4 nuggets. In the third and fifth weeks, kindergarteners verbally self-selected 2, 3, or 4 chicken nuggets. A Mann-Whitney test was used to determine a significant difference in intake between the 2 days kindergarteners were allowed to select the portion size and the 2 days they were preportioned.

No significant difference was found in milk, fruit, vegetable, or rice intake between choice and nonchoice lunches. In this study, kindergarteners ate more chicken nuggets when they were offered a larger portion size. Further investigation is needed on the impact of letting kindergarteners self-select portion sizes, and the potential negative outcomes of larger portion sizes on children's caloric consumption in elementary schools.

Effects of energy content and energy density of pre-portioned entr ées on energy intake. Pre-portioned entr ées are commonly consumed to help control portion size and limit energy intake. The influence of entr ée characteristics on energy intake, however, has not been well studied. In a crossover design, 68 non-dieting adults 28 men and 40 women were provided with breakfast, lunch, and dinner on 1 day a week for 4 weeks.

Each meal included a compulsory, manipulated pre-portioned entr ée followed by a variety of unmanipulated discretionary foods that were consumed ad libitum. Results showed that in men, decreases in the energy content and ED of pre-portioned entr ées acted independently and added together to reduce daily energy intake both P entr ée factors also had independent effects on energy intake at breakfast and lunch, but at dinner and for the entire day the effects depended on the interaction of the two factors P entr ées affect daily energy intake and could influence the effectiveness of such foods for weight management.

Reduced-portion entr ées in a worksite and restaurant setting: impact on food consumption and waste. Large portion sizes in restaurants have been identified as a public health risk. The purpose of the present study was to determine whether customers in two different food-service operator segments non-commercial worksite cafeteria and commercial upscale restaurant would select reduced-portion menu tysabri prise de poids nourrisson and the impact of selecting reduced-portion menu items on energy and nutrient intakes and plate waste.

Consumption and plate waste data were collected for 5 weeks before and 7 weeks after introduction of five reduced-size entr ées in a worksite lunch cafeteria and for 3 weeks before and 4 weeks after introduction of five reduced-size dinner entr ées in a restaurant setting. Full-size entr ées were available throughout the entire study periods.

A worksite cafeteria and a commercial upscale restaurant in a large US Midwestern metropolitan area. Adult worksite employees and restaurant patrons. Food waste, energy intake and intakes of total fat, saturated fat, cholesterol, Na, fibre, Ca, K and Fe were significantly lower when both full- and reduced-size entr ées were served in the worksite setting and in the restaurant setting compared with when only full-size entr ées were served.

A relatively small proportion of reduced-size entr ées were selected but still resulted in reductions in overall energy and nutrient intakes. These outcomes could serve as the foundation for future studies to determine strategies to enhance acceptance of reduced-portion menu items in restaurant settings.

Sabemos que hay que tener en cuenta los problemas de sueño para evitar recaídas en la adicción. Diferentes estudios han demostrado interacciones entre el sistema hipocretinérgico, los circuitos de respuesta aguda al estrés y los sistemas de recompensa.

También sabemos que la activación optogenética selectiva del sistema hipocretinérgico incrementa la probabilidad de la transición del sueño a la vigilia, y también es suficiente para iniciar un comportamiento compulsivo de recaída adictiva. La activación del sistema hipocretinérgico podría explicar la hipervigilia asociada al estrés y a la adicción. El mayor conocimiento de esta interacción permitiría entender mejor los mecanismos de la adicción y encontrar nuevas estrategias para el tratamiento de las adicciones.

The transmission of tegumentary leishmaniasis TL has increased in 9 provinces of Argentina since Santa Fe and Entre Ríos did not record in this period autochtonous probed cases: however, an epidemic outbreak took place in in Bella Vista, Corrientes, located in an area with ecological continuity and contiguous to both provinces.

In order to evaluate the potential risk of transmission of LT, Phlebotominae were captured at locations close to and southern from Bella Vista during February La Celina-Villa Urquiza captured individuals of Lutzomyia neivai In Tartagal, Santa Fe, the captures were consistent with the residual "chaco" landscape, 7 individuals of Lu. The risk of LT epidemic transmission in these provinces is highlighted, mainly due to the progressive southern tropicalization of the paranaense gallery forest.

Clinical and entomological surveillance is recommended. Comparaisons d'étalons primaires de fréquence par GPS. The well known GPS common-view method does not fit any more when using a single channel receiver: the clock comparison measurements exhibit a frequency stability at a few parts in over one day, depending on the distance between the clock, and the intrinsic best stability level limited by the GPS signal currently used can be calculated at 7.

But is can be shown that a 4 channel receiver, performing as many regular common-views as possible over each day, would allow to reach on actual measurements. That should also be the case for an other option: the use of the carrier phase of the GPS signal, associated with global geodetic computing. Deep exploratory drillings, i. Drilling began inand until now there have been 18 polls with very variable results in terms of mineralization, resource flow, and temperature. The aim of this study was to present a management model, which should allow operators of thermal complexes to further develop procedures for safeguarding the biodiversity of the ecosystems involved, both during exploration and exploitation activities.

The environmental management Plan proposed is constituted by a set of technical procedures that are formulated and should be performed during the stages of exploration and exploitation of the resource, and consists of: environmental monitoring, environmental audit, public information and contingency programs. This Plan describes the measures and proposals aimed at protecting environmental quality in the area of influence of a thermal complex project, ensuring that its execution remains environmentally responsibly, and allowing implementation of specific actions to prevent or correct environmental impacts, as predicted in the evaluation of the Environmental Program.

The audit of environmental impact includes and takes into account natural factors, such as water, soil, atmosphere, flora and fauna, and also cultural factors.

The technical audit Plan was prepared in order to get a systematic structure and organization of the verification process, and also with regard to document the degree of implementation of the proposed mitigation measures. Finally, an environmental contingency program was implemented, and its objective was to consider the safeguarding of life and its natural environment. Thus, a guide has been developed with the main actions to be taken on a contingency, since forecast increases the efficiency of the response.

This study estimated the prevalence of symptoms evocative of obstructive sleep apneoa OSA in patients with type 2 diabetes and the proportion of those with evidence of a previous diagnosis or diagnostic procedure.

In ENTREDpeople reimbursed for at least three antidiabetic agents within the last 12 months were randomly selected, and answered a self-administered questionnaire. Patients were considered to have evidence of a previous diagnostic procedure if they reported an OSA diagnosis or had a sleep recording done, or if a sleep recording was found in the hospital discharge or medical claims database, or if they were currently being treated with nocturnal ventilation.

The patients' mean age was 66 years. Around 8. Being male, obesity, high blood pressure, insulin treatment, living with a partner, lower educational level and financial difficulties were all associated with symptoms suggestive of OSA.

OSA is underdiagnosed in French diabetic patients, while the prevalence of symptoms is high. It is of the utmost importance to better diagnose OSA in the diabetic population. All rights reserved. Analyse des interactions energetiques entre un arena et son systeme de refrigeration.

In recent years, the proportion of agricultural crops in the rotations, especially that of soybean, has increased, thus leading to an increase in the need for land clearing to incorporate new lands for agricultural use.

Most of these lands are considered marginal for agricultural use. In addition rice farming with irrigation is a critical part of the Entre Ríos economy. Defining and assessing soil quality indicators SQI that show the evolution of the soil with different uses and management systems is a way to contribute to the knowledge of soil quality.

We identified the most representative soil subgroups corresponding to the orders Vertisols, Mollisols and Alfisols and defined the production systems livestock-agricultural, agricultural-livestock, agricultural without irrigation, and rice crop irrigated with water from groundwater and surface reservoirs. We also determined the physical, physico-chemical, chemical and microbiological variables of the soil, and characterized the quality of the water for irrigation.

The change in the use of the land responded to a favorable economic situation for agriculture that started in the 's.

However, the expansion of bioenergy feedstock production might cause unintended environmental consequences. Accordingly, the goal of this research is to investigate how forest-based bioenergy development across the Americas may affect hydrological systems on a watershed scale.

This study focuses on biofuel feedstock production with hybrid poplar cultivation in a snow-dominated watershed in northern Wisconsin, USA, and eucalyptus cultivation in a warm and temperate watershed in Entre Rios, Argentina. The Soil and Water Assessment Tool SWATcalibrated and validated for the two watersheds, is used to evaluate the effects of land use change corresponding to a range of biofuel development scenarios.

The land use change botox hiv positive jour include rules for limiting the location of the biofuel feedstock, and rotation time.

These variables in turn impact the magnitude and timing of runoff and evapotranspiration. In Wisconsin, long term daily streamflow simulations indicate that planting poplar will increase evapotranspiration and decrease water yield, primarily through reduced baseflow contributions to streamflow. Results are also presented in terms of changes in flow relative to biomass production, to understand the sensitivity of potential biofuel generation to hydrologic impacts, and vice versa.

In the end, alternative management practices were evaluated to mitigate the impacts. Changes in the energy and sodium content of main entr ées in US chain restaurants from to The food environment shapes individual diets, and as food options change, energy and sodium intake may also shift. Understanding whether and how restaurant menus evolve in response to labeling laws and public health pressures could inform future efforts to improve the food environment.

To track changes in the energy and sodium content of US chain restaurant main entr ées between spring when the Affordable Care Act was passed, which included a federal menu labeling requirement and spring Nutrition information was collected from top US chain restaurants' websites, comprising unique brands.

Descriptive statistics and regression analysis evaluated change across main entr ées overall and compared entr ées that were added, removed, and unchanged. Tests of means and proportions were conducted for individual restaurant brands to see how many made significant changes. Separate analyses were conducted for children's menus. Mean energy and sodium did not change significantly overall, although mean sodium was 70 mg lower across all restaurants in added vs removed menu items at the 75th percentile.

Changes were specific allaitement régime amaigrissant restaurant brands or service model: family-style restaurants reduced sodium among higher-sodium entr ées at the 75th percentile, but not on average, and entr ées still far exceeded recommended limits.

Fast-food restaurants decreased mean energy in children's menu entr ées by 40 kcal. A few individual restaurant brands made significant changes in energy or sodium, but the vast majority did not, and not all changes were in the healthier direction. Among those brands that did change, there were slightly more brands that reduced energy and sodium compared with those that increased it. Industry marketing and pledges may create a misleading perception that restaurant menus are becoming substantially healthier, but both healthy and unhealthy menu changes can occur simultaneously.

Our study found no meaningful changes overall across a 1-year time. Contexts of occurrence of child malnutrition in the district of Villaguay, Entre Ríos, Argentina. A multivariate analysis. The analysis of nutritional status is anthropologically important to address the complex interaction of biological, social, political, economic and cultural factors.

How calorie and price information influence ordering on restaurant menus with both half and full entr ée portion sizes. Many restaurants are increasingly required to display calorie information on their menus. We present a study examining how consumers' food choices are affected by the presence of calorie information on restaurant menus. However, unlike prior research on this topic, we focus on the effect of calorie information on food choices made from a menu that contains both full size portions and half size portions of entr ées.

This different focus is important because many restaurants increasingly provide more than one portion size option per entr ée. Additionally, we examine whether the impact of calorie information differs depending on whether full portions are cheaper per unit than half portions non-linear pricing or whether they have a similar per unit price linear pricing.

We find that when linear pricing is used, calorie information leads people to order fewer calories. This decrease occurs as people switch from unhealthy full sized portions to healthy full sized portions, not to unhealthy half sized portions.

In contrast, when non-linear pricing is used, calorie information has no impact on calories selected. Considering the impact of calorie information on consumers' choices from menus with more than one entr ée portion size option is increasingly important given restaurant and legislative trends, and the present research demonstrates that calorie information and pricing scheme may interact to affect choices from such menus.

Validation de modeles d'eclairement incident a la surface de l'eau en Arctique. Dans ce memoire, deux methodes d'estimation d'eclairement incident a la surface de l'Arctique sont evaluees. Une base de donnees in situ a ete constituee a partir de 16 campagnes oceanographiques en Arctique. Pour les dates ou l'eclairement est mesure, les estimations d'eclairement journalier incident a la surface obtenues a partir des satellites de la couleur de l'eau Frouin et al.

De meme, un exercise de comparaison entre les estimations satellitaires est produit pour l'annee sur tout le territoire Arctique. Les resultats montrent entre autres que la methode qui utilise les satellites de la couleur de l'eau est plus precise pour estimer l'eclairement sur une petite superficie puisqu'elle rend mieux les variations locales dans l'eclairement. La methode qui utilise les satellites meteorologique est plus precise pour estimer l'eclairement sur une grande superficie, puisqu'elle est moins restreinte dans les conditions qui permettent de fournir une estimation.

Design Energy intake, bite size, and comments about portion size were evaluated among 30 children at 2 series of lunches in which either an age-appropriate portion or a large portion of an entr ée was served. These increases were seen even though observational data indicated that the children were largely unaware of changes in portion size.

Greater responsiveness to portion size was associated with higher levels of overeating. Children with satiety deficits may be most susceptible to large portions.

Cohen, Juliana F. Background There are currently no national standards for school lunch period lengths and little is known about the association between the amount of time students have to eat and school food selection and consumption. Objectives To examine plate waste measurements from students in the control arm from the MEALS study school year for the association of the amount of time to eat with school meal selection and consumption.

Design Prospective study using up to six repeated measures among students over the school year. Main Outcome Measures School food selection and consumption were collected using plate waste methodology. There were no significant differences in entr ée, milk, or vegetable selection. School policies that encourage lunches with at least 25 minutes of seated time may reduce food waste and improve dietary intake.

Influence des interactions entre écrans de soutènement sur le calcul de la butée. La mobilisation de la butée devant un écran implique un volume de sol important, sur une distance plus grande que la fiche et qui dépend des paramètres du calcul. L'article passe mrsa treatment regimen revue les méthodes de calcul utilisées pour évaluer la butée, en insistant sur la distance nécessaire au libre développement du mécanisme de butée.

Il évalue ensuite de différentes façons l'effet de l'interaction entre deux écrans placés face à face de part et d'autre d'une excavation. La méthode recommandée pour calculer la butée mobilisable consiste à faire un calcul en éléments finis avec des valeurs réduites des paramètres de résistance au cisaillement dans la zone où se développera la butée.

Cette démarche permet de déterminer des facteurs correctifs à appliquer au calcul de la butée d'un écran isolé en oeuf regime sans sel large du rapport de la distance entre écrans à leur fiche. There are currently no national standards for school lunch period length and little is known about the association between the amount of time students have to eat and school food selection and consumption.

Our aim was to examine plate-waste measurements from students in the control arm of the Modifying Eating and Lifestyles at School study to school year to determine the association between amount of time to eat and school meal selection and consumption. We used a prospective study design using up to six repeated measures among students during the school year. One thousand and one students in grades 3 to 8 attending six participating elementary and middle schools in an urban, low-income school district where lunch period lengths varied from 20 to 30 minutes were included.

School food selection and consumption were collected using plate-waste methodology. Logistic regression and mixed-model analysis of variance was used to examine food selection and consumption. Among those who selected a meal component, students with entr ée P entr ée, milk, and vegetable consumption compared with students who had more time to eat. School policies that encourage lunches with at least 25 minutes of seated time might reduce food waste and improve dietary intake.

Meat samples inoculated with L. Depending upon the temperature, D-values at 0 ppm of GSE ranged from A reduction in time of The z-values of L. Estimated thermal lethality for a 7-D log reduction of L. The results of this study will assist the retail food industry in designing acceptance limits on critical control points pertaining to cooking regimes to effectively eliminate L. Energy, saturated fat, and sodium were lower in entr ées at chain restaurants at 18 months compared with 6 months following the implementation of mandatory menu labeling regulation in King County, Washington.

Policies on menu labeling have been proposed as a method to improve the food environment. However, there is little information on the nutrient content of chain restaurant menu items and changes over time. To evaluate the energy, saturated fat, and sodium content of entr ées 6 and 18 months post-implementation of restaurant menu labeling in King County of Washington State for items that were on the menu at both time periods, and across all items at 6 and 18 months and to compare energy content to recommendations provided by the Dietary Guidelines for Americans.

One establishment per chain was audited at each time period. The content of entr ées at 18 months was compared with one-third assuming three meals per day of the nutrient intake recommendations for adults provided by the Dietary Guidelines for Americans.

The audit included 37 eligible chains of 92 regulated chains. Energy contents were lower all chainssit downand quick service ; paired t tests P entr ées that were on the menu at both time periods. There was a significant trend across quartiles for a decrease in energy, saturated fat, and sodium for all entr ées at sit-down chains only.

Modest improvements in the nutrient content of sit-down and quick-service restaurant entr ées occurred but overall levels for energy, saturated fat, and sodium are excessive. Spectro-imagerie optique a faible flux et comparaison de la cinematique Halpha et HI d'un echantillon de galaxies proches. It allows the EMCCD to be used for photon counting by drastically taking down its dominating source of noise: the clock induced charges. It has been characterized in laboratory and tested at the observatoire du mont Megantic.

When compared to the previous generation of photon counting cameras based on intensifier tubes, this new camera renders the observation of the galaxies kinematics with an integral field spectrometer with a Fabry-Perot interferometer in Halpha light much faster, and allows fainter galaxies to be observed.

The integration time required to reach a given signal-to-noise ratio is about 4 times less than with the intensifier tubes. Many applications could benefit of such a camera: fast, faint flux photometry, high spectral and temporal resolution spectroscopy, etats unis regime politique diffraction limited imagery lucky imagingetc. Technically, the camera is dominated by the shot noise for flux higher than 0.

The 21 cm emission line of the neutral hydrogen HI is often used to map the galaxies kinematics. The extent of the distribution of the neutral hydrogen in galaxies, which goes well beyond the optical disk, is one of the reasons this line is used so often.

However, the spatial resolution of such observations is limited when compared to their optical equivalents. When comparing the HI data to higher resolution ones, some differences were simply attributed to the beam smearing of the HI caused by its lower resolution.

The comparison will try to determine whether the sole beam smearing is responsible of the differences observed. The results shows that intrinsic dissimilarities between the kinematical tracers used are responsible of some of the observed disagreements.

The understanding of theses differences is of a high importance as the dark matter distribution, inferred from the rotation of the galaxies, is a test to some cosmological models. Comparaison de la performance environnementale de la production thermique d'electricite avec et sans sequestration geologique du dioxyde de carbone. The research project hypothesis is that CO2 capture and sequestration technologies CSC leads to a significant decrease in global warming, but increases the impact of all other aspects of the study.

This is because other processes used for CO2 capture and sequestration require additional quantities of raw materials and energy. Two other objectives are described in this project. The first is the modeling of an Integrated Gasification Combined Cycle power plant for which there is no known generic data.

The second is to select the right hypothesis regarding electrical production technologies, CO2 capture, compression and transportation by pipeline and finally sequestration. LCA is an exhaustive quantitative method used to evaluate potential environmental impacts associated with a product, a service or an activity from resource extraction to waste elimination. In order to sequester CO2 in geological formation, it is necessary to extract CO2from emission flows. For the NGCC power plant, the capture was done during the afterburning phase.

Once the CO2 was isolated, it was compressed and directed through a transportation pipe 1 km in length on the ground surface and in the sea. It is hypothesized that the power plant is km from the shore and the sequestration platform km from France's shore, in the North Sea.

The IGCC power plant modeling and data selection regarding CO2 capture and sequestration were done by using primary data from the industry and the Ecoinvent generic database Version 1. This database was selected due to its European source. Finally, technical calculations and literature were used to complete the data inventory.

This was validated by electrical experts in order to increase data and modeling precision. The main contributor was the additional quantity of energy required to operate CO2 capture and compression facilities. This additional energy negatively affected the power plant's global efficiency because of the increase in the quantity of fossil fuel that needed to be extracted and consumed.

The increase in other impacts was mainly due to additional electricity, fossil fuel for extracting, treatment and transportation and additional emissions generated during power plant operations. A scenario analysis was done to study the sensitivity and variability of uncertain data during the software modeling process of a power plant. Data on power plant efficiency is the most variable and sensitive during modeling, followed by the length of the transportation pipe and the leaking rate during CO2 sequestration.

This result analysis is interesting because it led to the maximum efficiency scenario with capture with a short CO 2 transportation distance and a low leaking rate obtaining better results on all impact category indicators, compared to the minimum efficiency scenario without capture.

In fact, positive results on all category indicators were possible during the system comparison between the two cases with and without capture. Abstract shortened by UMI.

Comparaison des théories des mouvements des satellites de Saturne avec des observations de phénomènes. As every fifteen years, phenomena occurred among the Saturnian system of satellites in Because the Sun and Earth passed through the equatorial plane of the planet which is close to the orbital planes of its main satellites, eclipses and occultations by Saturn occur as well as eclipses and occultations of a satellite by another. These phenomena lead to accurate astrometric observations; therefore the authors organized an international campaign to observe them.

At the present time, they have collected one hundred of such mutual events and have analyzed half of them. Um total de 5. This system is one of the most important groundwater reservoirs; it is shared by four neighboring countries covering an area larger than one million square kilometers.

The geological units closely related to the Guaraní Aquifer are the Piramboia and Botucatu Formations that consist of Triassic-Jurassic aeolian, fluvial and lacustrine sandstones, and the Serra Geral basalts with clastic intercalations.

Serra Geral, an effusive Cretaceous complex, covers the sandstones and provides a high degree of confinement to the system. This paper presents the interpretation of magnetotelluric MT data collected during in Entre Ríos Province, Argentina.

These data, recorded in three profiles, mainly provide the depth to the crystalline basement, determinant for the presence of aquifer-related sediments. Models showed that the discrimination of the basalts strongly depends on local electrical characteristics. Model information is quite consistent with the information from oil and thermal wells located close to the profiles. Entre Familia: Reflejos de Salud was a successful family-based randomized controlled trial designed to improve dietary behaviors and intake among U.

The novel intervention design merged a community health worker promotora model with an entertainment-education component. This process evaluation examined intervention implementation and assessed relationships between implementation factors and dietary change.

Participants included mothers randomized to an intervention condition. Process evaluation measures were obtained from participant interviews and promotora notes and included fidelity, dose delivered i. Outcome variables included changes in vegetable intake and the use of behavioral strategies to increase dietary fiber and decrease dietary fat intake.

Participant satisfaction was high, and fidelity was achieved; Trends suggested that keeping families in the prescribed intervention timeline and obtaining support from other social network members through sharing of program materials may improve changes. Study findings elucidate the relationship between specific intervention processes and dietary changes.

The concept of "Cosmography" is in disuse since the 80s of the last century, but the astronomical themes previously discussed in the school subjects of Geography and Cosmography remain in current textbooks.

The use of term "Cosmography" was rescued in this research, and the study of its re-signification prompted the appearance of the term Geographic Cosmography. The Geographic Cosmography is a field of studies of the Geography, whose set of knowledge and skills is predominantly scholar.

It studies the interface between terrestrial and celestial knowledge, and assigns a geographic significance to them. It examines human and natural relationships with Sidereal Space and its consequences for society and nature.

Etude des phenomenes chimiques au contact entre le bloc cathodique et la barre collectrice d'une cellule d'electrolyse d'aluminium.

La production d'aluminium est une industrie importante au Québec. Les propriétés de ce métal le vouent à de multiples usages présents et futurs dans le cadre d'une économie moderne durable. Toutefois, le procédé Hall-Héroult est très énergivore et des progrès demeurent donc nécessaires pour en diminuer les coûts financiers et environnementaux.

Parmi les améliorations envisageables de la cellule d'électrolyse se trouve le contact entre la cathode et la barre collectrice, qui doit offrir une faible résistivité au passage du courant électrique.

En cours d'opération de la cellule, ce contact a tendance à se dégrader, générant des pertes énergétiques significatives. Le but du présent projet était donc d'étudier les phénomènes chimiques se produisant au contact bloc-barre de la cellule d'électrolyse Hall-Héroult.

En premier lieu, un aspect crucial à considérer est la pénétration du bain électrolytique dans la cathode, car des composés de bain atteignent éventuellement la barre collectrice et peuvent y réagir. A cet effet, une méthode novatrice a été développée afin d'étudier les cathodes et la pénétration du bain dans celles-ci à l'aide de la microtomographie à rayons X.

Cette méthode rapide et efficace s'est avérée fort utile dans le projet et a un potentiel important pour l'étude future des cathodes et des phénomènes qui s'y produisent. Ensuite, une cellule d'électrolyse rectangulaire à petite échelle a été développée. Plusieurs phénomènes observés 'en industrie sur des autopsies de cellules post-opération et rapportés dans la littérature ont été reproduis avec succès à l'aide de cette cellule expérimentale.

Puis, des tests sans électrolyse, ciblant l'effet du bain électrolytique sur l'acier, ont aussi été conçus et complétés afin de s. Pincharse sin infectarse: estrategias para prevenir la infección por el VIH y el VHC entre usuarios de drogas inyectables. Estas intencionalidades no son mutuamente excluyentes. À ce jour. Le transfert de connaissances entre les mathematiques et les sciences.

Une etude exploratoire aupres d'eleves de 4e secondaire. Au moment ou dans plusieurs pays on travaille a refondre les programmes d'etudes, tant au primaire qu'au secondaire, l'interet pour le transfert renait.

Un des concepts fondamentaux en apprentissage consiste en l'habilete a reutiliser de facon consciente et efficace un acquis d'une situation a une autre situation. Cette recherche emane de preoccupations professionnelles au moment ou le chercheur etait enseignant au secondaire.

Au cours de ces annees, il lui a ete possible de constater que plusieurs eleves percevaient difficilement les liens presents entre les disciplines mathematiques et scientifiques. Des travaux en psychologie cognitive et plus particulierement selon une perspective du traitement de l'information ont servi de cadre de reference pour evaluer et analyser les capacites de transfert aupres d'eleves de 4e secondaire.

Ce cadre de reference permet de formuler le principal objectif qui est de mieux comprendre le processus de transfert chez des eleves en situation de resolution de problemes scientifiques. Cette these s'interesse donc au transfert en tant que phenomene important du processus d'apprentissage au sens de l'integration. La methode de recherche choisie, de nature qualitative, est principalement axee sur l'evaluation de la capacite a transferer des connaissances lors d'une epreuve et d'un entretien.

Pour evaluer ce potentiel de transfert, nous avons elabore deux outils: une epreuve en mathematiques et en sciences et un guide d'entretien. Pour la passation de l'epreuve, le chercheur a pu compter sur la collaboration de sujets provenant de deux ecoles.

L'entretien complete la prise de donnees avec 13 sujets ayant accepte de poursuivre l'etude. Les donnees recueillies par ces instruments font ensuite l'objet d'une analyse de contenu. En premier lieu, les verbatims de l'epreuve et de l'entretien ont ete transcrits, puis codifies. La correction des reponses fournies pour les problemes resolus s'est faite a partir d'une grille d.

Association entre les hormones sexuelles, les marqueurs de remodelage osseux et la densité minérale osseuse chez des femmes ménopausées d'origine marocaine étude transversale.

Méthodes Il s'agit d'une étude transversale, menée sur une période de 6 mois d'octobre à fin avril et ayant fait participer deux cent deux Les conducteurs organiques quasi-bidimensionnels kappa-ET2X presentent d'importantes similitudes avec les SCHT telles qu'une phase isolant de Mott, un regime de pseudogap et un etat supraconducteur.

L'etude de leurs proprietes apparait donc complementaire. Parmi les interrogations persistantes concernant la physique de ces systemes, l'origine du ou des processus exotique d'appariement, responsable de la supraconductivite est le sujet suscitant l'interet le plus marque dans la communaute.

L'hypothese d'un mecanisme lie a la proximite d'un etat antiferromagnetique est privilegiee. Une etape importante dans la resolution de cette problematique est l'identification de la symetrie du parametre d'ordre. D'apres de nombreux travaux sur les systemes fortement correles, la sonde ultrasonore, de par sa sensibilite aux excitations de quasiparticule a basse temperature, est consideree comme particulierement adaptee a l'etude de cette propriete.

Cependant, son emploi necessite l'utilisation d'un compose metallique a basse temperature et completement supraconducteur. En effet, il est situe loin de la transition du premier ordre de Mott et est completement supraconducteur. De facon surprenante, ce systeme semble se coupler fortement avec le reseau ce qui augmente significativement la sensibilite de cette sonde aux proprietes du gaz electronique.

Cependant, des difficultes techniques importantes, liees a la nature intrinseque de ce materiau, doivent etre surmontees pour proceder a des mesures suivant differentes polarisations. La presente etude a profondement modifie notre comprehension de ce systeme. En effet, ces mesures ont permis de constater que le kappa-ET2Cu[N CN 2]Br injection botox nantes un compose qui est situe en bordure de la zone de coexistence entre la supraconductivite et le magnetisme, ce qui constitue un resultat totalement inattendu.

De plus, la.
