Revista da Sociedade Brasileira de Fonoaudiologia , 2012, DOI: 10.1590/S1516-80342012000200012
Abstract: purpose: to investigate the myofunctional characteristics of nasal and oral breathing in obese individuals. methods: participants were 24 obese individuals with ages between 8 and 15 years, who participated in the obesity group of the ambulatory of pediatrics of an university hospital, and were selected by convenience. the myofunctional characteristics were assessed using the orofacial myofunctional assessment with scales (avalia??o miofuncional orofacial com escalas - amiofe) protocol. results: oral breathing was present in 62.5%, and nasal breathing in 37.5% of the population studied. in the oral breathing group, 40% of the subjects presented lips tension during occlusion and 80% showed a narrow palate, while almost all nasal breathers had normal palate and lips posture (p<0.05). interposition of the tongue in the dental arches occurred in 47% of oral breathers and none of the nasal breathers. oral breathers showed the tendency not to repeat the swallowing of the same bolus. no difference was found between groups regarding face appearance, jaw posture, cheeks, and chewing function. conclusion: oral breathing in obese children and adolescents was accompanied by myofunctional alterations of the stomatognathic system, represented by narrow palate, interposition of the tongue in the dental arches, occlusion of the lips with tension, and swallowing disorders.

Revista de Saúde Pública , 2010, DOI: 10.1590/S0034-89102010000200005
Abstract: objective: to understand beliefs and attitudes about fluorosis among young people living in a rural area. methodological procedures: qualitative study consisting of semi-structured interviews with 23 adolescents with dental fluorosis, 14 teachers and three health authorities in the city of s?o francisco, southeastern brazil, in 2002. content analysis and social representation theory were applied. analysis of results: the organoleptic characteristics of carbonates that affect groundwater (salty flavor, whitish coloration, and turbidity) associated with negative aspects of household use of this water are considered a cause of mottled enamel. even after contact with researchers who investigated this phenomenon and helped find a solution for this condition, the local population is still unwilling to accept fluoride as the cause of the problem and does not fully agree to use water from other sources because they are afraid of the quality of water. conclusions: misperceptions of the causes of dental fluorosis and water treatment costs compromise the implementation of uncontaminated surface water supplies. health education strategies are required in parallel with solutions for securing water supply in drought-ravaged areas.

Abstract: Cet article interroge les pratiques gestionnaires de deux entreprises de services urbains, filiales des groupes fran ais Suez et EDF qui sont intervenues dans les années 1990 et 2000 dans la distribution privatisée de l’eau et de l’électricité à Buenos Aires. Le questionnement repose sur les dispositifs de gestion que ces organisations ont alors mis en place à destination des habitants de quartiers défavorisés, nouveaux acteurs d’une relation de service marchandisée , dont la particularité est qu’ils sont peu solvables, souvent installés de manière informelle, voire clandestine, au c ur d’un véritable problème politique . Nous interrogeons ainsi, grace aux grilles de lecture proposées par la sociologie de la gestion notamment, les outils mis en place par ces entreprises, les dynamiques de recomposition, d’innovation ou de métissage de dispositifs de gestion importés des expériences européennes (formation) ou de projets de développement (modalité participative d’intervention). Nous questionnons également l’émergence d’une nouvelle profession d’ ingénieur social dans un contexte particulier de très forte polarisation sociale, ainsi que les analyses connexes relatives aux modes de légitimation et d’ancrage de cette nouvelle profession. This article looks at the management practices of two urban service enterprises, subsidiaries of the French groups Suez and EDF, who intervened in the 1990’s and after 2000 in the privatized distribution of water and electricity in Buenos Aires. The questioning involves the management arrangements that these organizations set up for the inhabitants of the downtrodden quarters, new actors in a “merchandized” service relationship, whose particularity is that they are practically insolvent, often housed informally, or in a clandestine manner, at the heart of a truly “political problem”. Thanks to question charts, notably proposed by the sociology of management, we thus ask about the tools set up by these enterprises, i.e., the dynamics of recombining, innovating or crossbreeding management arrangements “imported” from European experiences (training) and about development projects (participative types of intervention). We also investigate the emergence of a new profession of “social engineer” in a particular context of very high social polarization, as well the related analyses involving modes of legitimization and anchorage of this new profession.

Abstract: Les unités de production en lits fluidisés catalytiques sont apparues vers 1942 dans l'industrie pétrolière et vers 1960 dans l'industrie chimique. On se limitera ici au problème de l'extrapolation des lits fluidisés catalytiques pour l'industrie chimique, qui exigent de très hautes performances (> 99 % de conversion). Leur mise au point a, dans le passé, nécessité l'exploitation sur des sites industriels de co teux pilotes de 0,5 m de diamètre et de plus de 10 m de hauteur. Nous montrerons que ces pilotes peuvent être évités et que le passage direct du laboratoire à l'échelle industrielle est réalisable. Cette possibilité offre en plus une méthode simple pour améliorer les catalyseurs des unités industrielles. Elle ouvre aussi cette technique, très appréciée en production, aux produits de petits tonnages. La présentation de cet article sera faite en trois parties : - La première, présentée ci-après, expose les problèmes majeurs posés par l'extrapolation, puis résume les études effectuées. Les travaux d'extrapolation relatifs à deux procédés effectués avec des pilotes sont ensuite présentés, à titre d'exemples. De ces travaux sont déduites les performances que l'on peut espérer obtenir avec un réacteur catalytique à lit fluidisé, ainsi que les règles de tendances à suivre pour y parvenir. - La deuxième partie, intitulée Stratégie n'utilisant que des expériences de laboratoire , propose une stratégie expérimentale permettant d'obtenir en laboratoire les informations nécessaires pour passer directement à l'échelle industrielle avec des expériences suggérées en partie par les résultats exposés dans le premier article. Les relations expérimentales établies lors de ces études montrent que les propriétés d'un lit fluidisé ne dépendent (mis à part quelquefois le diamètre du réacteur) que d'un paramètre appelé vitesse minimum de fluidisation de comportement . - La troisième partie est intitulée études théoriques, réalités expérimentales, suggestions . Les bulles des lits fluidisés ont fait l'objet de très nombreux travaux, dont les résultats sont très souvent explicités sous la forme de modèles mécanistiques à un paramètre qui est le diamètre des bulles. Pour confronter ces modèles à l'expérience, une relation est établie entre le diamètre des bulles et la vitesse minimum de fluidisation de comportement. Des suggestions sont alors faites pour améliorer les modèles, et l'on propose des conclusions générales sur les lits fluidisés. The firsts catalytic fluidized beds appear near 1942 in petroleum industry and near 1960 in chemical industry. We only consider very h

Abstract: The present paper examines the relationship between hydrochemical characteristics and endemic dental fluorosis, controlling for variables with information on an individual level. An epidemiological survey was carried out in seven rural communities in two municipalities in the state of Minas Gerais, Brazil. The Thystrup & Fejerskov index was employed by a single examiner for the diagnosis of dental fluorosis. A sampling campaign of deep groundwater in the rural communities of interest was carried out concomitantly to the epidemiological survey for the determination of physiochemical parameters. Multilevel modeling of 276 individuals from seven rural communities was achieved using the non-linear logit link function. Parameters were estimated using the restricted maximum likelihood method. Analysis was carried out considering two response variables: presence (TF 1 to 9) or absence (TF = 0) of any degree of dental fluorosis; and presence (TF ≥ 5—with loss of enamel structure) or absence of severe dental fluorosis (TF ≤ 4—with no loss of enamel structure). Hydrogeological analyses revealed that dental fluorosis is influenced by the concentration of fluoride (OR = 2.59 CI95% 1.07–6.27; p = 0.073) and bicarbonate (OR = 1.02 CI95% 1.01–1.03; p = 0.060) in the water of deep wells. No other variable was associated with this prevalence (p > 0.05). More severe dental fluorosis (TF ≥ 5) was only associated with age group (p < 0.05). No other variable was associated to the severe dental fluorosis (p > 0.05). Dental fluorosis was found to be highly prevalent and severe. A chemical element besides fluoride was found to be associated (p > 0.05) to the prevalence of dental fluorosis, although this last finding should be interpreted with caution due to its p value.
