Celiac disease in the Mediterranean area

Background: The World Gastroenterology Organization recommends developing national guidelines for the diagnosis of Celiac Disease (CD): hence a profile of the diagnosis of CD in each country is required. We aim to describe a cross-sectional picture of the clinical features and diagnostic facilities in 16 countries of the Mediterranean basin. Since a new ESPGHAN diagnostic protocol was recently published, our secondary aim is to estimate how many cases in the same area could be identified without a small intestinal biopsy. Methods: By a stratified cross-sectional retrospective study design, we examined clinical, histological and laboratory data from 749 consecutive unselected CD children diagnosed by national referral centers. Results: The vast majority of cases were diagnosed before the age of 10 (median: 5 years), affected by diarrhea, weight loss and food refusal, as expected. Only 59 cases (7.8%) did not suffer of major complaints. Tissue transglutaminase (tTG) assay was available, but one-third of centers reported financial constraints in the regular purchase of the assay kits. 252 cases (33.6%) showed tTG values over 10 times the local normal limit. Endomysial antibodies and HLA typing were routinely available in only half of the centers. CD was mainly diagnosed from small intestinal biopsy, available in all centers. Based on these data, only 154/749 cases (20.5%) would have qualified for a diagnosis of CD without a small intestinal biopsy, according to the new ESPGHAN protocol. Conclusions: This cross-sectional study of CD in the Mediterranean referral centers offers a puzzling picture of the capacities to deal with the emerging epidemic of CD in the area, giving a substantive support to the World Gastroenterology Organization guidelines.

Transonic wind tunnel for investigation of turbomachinery blades

The design of a two-stream wind tunnel was undertaken to allow the simulation and study of certain features of the flow field around the blades of high-speed axial-flow turbomachineries. The mixing of the two parallel streams with designed Mach numbers respectively equal to 1.4 and 0.7 will simulate the transonic Mach number distribution generally obtained along the tips of the first stage blades in large bypass-fan engines.

The GALCIT hypersonic compressor plant will be used as an air supply for the wind tunnel, and consequently the calculations contained in the first chapter are derived from the characteristics and the performance of this plant.

The transonic part of the nozzle is computed by using a method developed by K. O. Friedrichs. This method consists essentially of expanding the coordinates and the characteristics of the flow in power series. The development begins with prescribing, more or less arbitrarily, a Mach number distribution along the centerline of the nozzle. This method has been programmed for an IBM 360 computer to define the wall contour of the nozzle.

A further computation is carried out to correct the contour for boundary layer buildup. This boundary layer analysis included geometry, pressure gradient, and Mach number effects. The subsonic nozzle is calculated {including boundary layer buildup) by using the same computer programs. Finally, the mixing zone downstream of the splitter plate was investigated to prescribe the wall contour correction necessary to ensure a constant-pressure test section.

Specklegram in a grapefruit fiber and its response to external mechanical disturbance in a single-multiple-single mode fiber structure

Specklegram in multimode fiber has successfully been used as a sensor for detecting mechanical disturbance. Speckles in a multimode pure silica grapefruit fiber are observed and compared to that of a step-index multimode fiber, showing different features between them. The sensitivities to external disturbance of two kinds of fiber were measured, based on single-multiple-single mode (SMS) fiber structure. Experimental results show that the grapefruit fiber shows higher sensitivity than does the step-index multimode fiber. The transmission spectrum of the grapefruit fiber was measured as well, showing some oscillation features that are significantly different from that of a step-index multimode fiber. The experiments may provide suggestions to understand the mechanisms of light propagation in grapefruit fibers. (D 2008 Optical Society of America.

Measuring the influence of customer-based store brand equity in the purchase intention

[EN] Store brands account for and important market share in the Spain and a further increase in expected in the next years due to the downturn. However, there is lack of research on store brand customer-based Brand Equity. This study attempts to propose an integrated model of Brand Equity in store or retailer brands, based on Aaker s well-known conceptual model. We propose a consumer-based model, including the main sources or dimensions of Brand Equity and considering the intention to purchase as a consequence. Based on a sample of 362 consumers and 5 store brands, structural equation modeling is used to test research hypotheses. The results obtained reveal that store brand awareness, loyalty along with store brand perceived quality have a significant influence on consumers intention to purchase store brands. Our study suggests that marketers and marketing managers from retailing companies should carefully consider the Brand Equity components when designing their brand strategies, and develop marketing activities in order to enhance their brands awareness.

A querela do declínio do simbólico: perspextivas e impasses do pensamento de Slavoj iek

Esse estudo tem por objetivo principal analisar as reflexões do filósofo e psicanalista teórico esloveno Slavoj iek acerca dos impactos subjetivos das transformações normativas ocorridas no Ocidente nos últimos cinqüenta anos. O problema do chamado declínio do Simbólico passou a ser amplamente discutido pela comunidade de psicanalistas lacanianos na qual se insere o filósofo a partir do final da década de 1990, o que constituiu uma inovação em um campo fortemente influenciado pela concepção estruturalista da subjetividade. Situando o autor como pioneiro na utilização de ferramentas conceituais lacanianas para a análise do social, o estudo divide-se em duas partes. Na primeira delas, exponho as bases teóricas do pensamento de iek, contextualizando o seu itinerário intelectual e político, e abordando as suas três linhas fundamentais de investigação: a filosofia política, a discussão sobre o ato ético e a ontologia do sujeito. Assim, o primeiro capítulo retraça o percurso que vai dos primeiros estudos sobre o funcionamento ideológico nos regimes totalitários à abordagem pop filosófica da ideologia na atualidade. Em seguida, apresento a sua redescrição da noção de comunismo à luz da tese dos novos antagonismos do capitalismo tardio. Por fim, trato da perspectiva universalista do filósofo a partir de sua leitura materialista do cristianismo, lançando mão sobretudo dos estudos de Alain Badiou sobre São Paulo. No segundo capítulo, delineamos as coordenadas centrais da concepção de sujeito em iek, cuja originalidade reside na articulação das formulações de Lacan e Hegel. As noções de grande Outro, objeto pequeno a, pulsão de morte e negatividade são tomadas como os pilares nos quais se assenta a descrição do sujeito iekiano. Na segunda parte do estudo, examinamos as teses de iek a respeito das relações entre subjetividade e cultura, com ênfase nos novos impasses que daí decorrem. As inibições que sucedem à injunção de gozar sem entraves, a melancolização do laço social, as metamorfoses da culpa, a vitimologia e a culpabilização do Outro são os tópicos centrais que sobressaem desse recorte. Nessa parte do trabalho, as reflexões de iek são cotejadas com as análises de autores de orientação lacaniana, considerados representativos desse tipo de discussão, como Jean-Pierre Lebrun, Charles Melman, Dany-Robert Dufour e Roland Chemama. Pretende-se com isso enriquecer a discussão, apontando as aproximações e distâncias que o pensamento de iek entretém com os referidos autores. O capítulo final do trabalho é consagrado ao exame crítico da démarche iekiana acerca do declínio do Simbólico. Dois tópicos de seu discurso são analisados, a saber: a) seu posicionamento ambivalente no que tange à crítica do catastrofismo; b) seu esforço de expurgar da noção de ato ético na qual ele quer encontrar saídas para os embaraços engendrados pelo dito declínio do Simbólico qualquer traço de pertencimento à tradição moral judaico-cristã, guardando dessa tradição apenas o exemplo do aspecto formal do ato. Para empreender tal exame, nos servimos, de um lado, do estudo crítico do sociólogo francês Alain Ehrenberg sobre a declinologia noção por ele cunhada para se referir ao conjunto de estudos que enfatizam o atual risco da dissolução dos laços sociais , e de outro lado, nos apoiamos na concepção de ética do filósofo neo-pragmatista Richard Rorty.

Effects of lunar cycle and fishing operations on longline-caught pelagic fish: fishing performance, capture time, and survival of fish

Commercial longline fishing data were analyzed and experiments were conducted with gear equipped with hook timers and timedepth recorders in the Réunion Island fishery (21°5ʹS lat., 53°28ʹE long.) to elucidate direct and indirect effects of the lunar cycle and other operational factors that affect catch rates, catch composition, fish behavior, capture time, and fish survival. Logbook data from 1998 through 2000, comprising 2009 sets, indicated that swordfish (Xiphias gladius) catch-per unit of effort (CPUE) increased during the first and last quarter of the lunar phase, whereas albacore (Thunnus alalunga) CPUE was highest during the full moon. Swordfish were caught rapidly after the longline was set and, like bigeye tuna (Thunnus obesus), they were caught during days characterized by a weak lunar illumination—mainly during low tide. We found a significant but very low influence of chemical lightsticks on CPUE and catch composition. At the time the longline was retrieved, six of the 11 species in the study had >40% survival. Hook timers indicated that only 8.4% of the swordfish were alive after 8 hours of capture, and two shark species (blue shark [Prionace glauca] and oceanic whitetip shark [Carcharhinus longimanus]) showed a greater resilience to capture: 29.3% and 23.5% were alive after 8 hours, respectively. Our results have implications for current fishing practices and we comment on the possibilities of modifying fishing strategies in order to reduce operational costs, bycatch, loss of target fish at sea, and detrimental impacts on the environment.

Da lama ao ou(t)ro: Cobra Norato, a gestação de um brasil...

Cobra Norato (1931), do autor gaúcho Raul Bopp (1898-1984), constitui uma das mais significativas obras do Modernismo brasileiro. Neste poema, dividido em 33 pequenos cantos, o personagem central é um homem que, após apossar-se da pele serpentária, empreende uma viagem em busca de sua amada, a filha da rainha Luzia, em poder de Cobra Grande, lendário vilão. Sendo o protagonista um viajante, Cobra Norato faz da travessia uma noção extremamente produtiva. Observaremos no estudo proposto, em que medida a ideia do deslocamento corrobora para uma das principais metáforas boppianas, manifestada na visão empática que seu texto instaura. De raízes folclóricas, com ressonâncias da literatura popular e inspirado num mito amazônico, Raul Bopp busca, pelo trabalho literário, criar uma linguagem adequada ao mundo que tematiza. Aproveitamos o conceito de imagem concebido por Aby Warburg (2010) para analisar como esta poética reproduz em suas nuances, a lógica da sobrevivência. Com Gaston Bachelard (1991) e Jean-Pierre Richard (1954) estudamos ainda as leituras que a presença da matéria lamacenta, intensamente presente na terra do Sem-fim, espaço de travessia do herói, pôde suscitar parte do sentido de descida primitivista. Vale ressaltar que o poema em questão foi idealizado sob as inspirações da corrente Antropofágica, desse modo, também pretendemos problematizar como os signos de tal projeto estético-ideológico são trabalhados no campo metafórico da poesia. Por isso destacamos, paulatinamente, a atenção dada ao desejo de unir duas pontas temporais a Idade de Ouro em que nos encontrávamos, segundo a visão mítica do paraíso nos textos da formação da nacionalidade, e a Idade de Ouro a que chegaríamos, depois da revisão crítica da corrente antropofágica , reafirmando o modelo de sociedade idealizado pela antropofagia (ANDRADE, 1928). Com auxílio de Lígia Morrone Averbuck (1985), Vera Lúcia Oliveira (2002), Otho Moacyr Garcia (1962), M. Cavalcante Proença (1971), Lúcia Sá (2012) entre outros, a pesquisa também pretende pôr em questão algumas das principais interpretações sobre Cobra Norato e fomentar o debate em torno dos dilemas e contradições de uma identidade cultural miscigenada, discussão também alcançada na malha simbólica do poema

Dynamics of Multi-Stage Bladed Disks Systems

This paper presents a new and original method for dynamical analysis of multistage cyclic structures such as turbomachinery compressors or turbines. Each stage is modeled cyclically by its elementary sector and the interstage coupling is achieved through a cyclic recombination of the interface degrees of freedom. This method is quite simple to set up; it allows us to handle the finite element models of each stage's sector directly and, as in classical cyclic symmetry analysis, to study the nodal diameter problems separately. The method is first validated on a simple case study which shows good agreements with a complete 360 deg reference calculation. An industrial example involving two HP compressor stages is then presented. Then the forced response application is presented in which synchronous engine order type excitations are considered.

Solitary magnon excitations in a one-dimensional antiferromagnet with Dzyaloshinsky-Moriya interactions

We investigate solitary excitations in a model of a one-dimensional antiferromagnet including a single-ion anisotropy and a Dzyaloshinsky-Moriya antisymmetric exchange interaction term. We employ the Holstein-Primakoff transformation, the coherent state ansatz and the time variational principle. We obtain two partial differential equations of motion by using the method of multiple scales and applying perturbation theory. By so doing, we show that the motion of the coherent amplitude must satisfy the nonlinear Schrodinger equation. We give the single-soliton solution.
