A REPRESENTAÇÃO MIDIÁTICA DO PROFESSOR BRASILEIRO NAS PÁGINAS BRANCAS E AMARELAS DE VEJA E CARTACAPITAL

Esta pesquisa fundamenta-se em uma perspectiva psicossocial da Teoria das Representações Sociais, sistematizada por Serge Moscovici, Denise Jodelet e demais colaboradores, com o objetivo de analisar como revistas informativas semanais (Veja e CartaCapital) representam questões relacionadas ao professor. A temática, do ponto de vista teórico, justifica-se em face do papel fundamental da mídia na sociedade contemporânea como difusora e produtora de informações. Foram levantados produtos jornalísticos publicados, durante um ano, na maior e mais importante revista semanal de informação do País (Veja) e em CartaCapital sobre a temática professor e suas variantes. O único critério para seleção dos textos foi que versassem sobre o professor brasileiro, independentemente do grau de ensino, sendo incluídas reportagens, entrevistas e/ou artigos opinativos. Esta investigação abarca ainda como recurso teórico-metodológico, o conceito de representações midiáticas conforme elaborado por Sary Calonge. Foram analisados 79 produtos jornalísticos entre janeiro de 2012 e janeiro de 2013 que indicaram que o professor é praticamente um ser invisível nas pautas de reportagens e artigos desses veículos de comunicação. Professor para falar sobre educação, só se for da área econômica. Nas poucas vezes em que é mencionado ou até aparece com algum destaque, percebe-se o uso de estereótipos e clichês, o que aponta a existência de um discurso naturalizado na mídia que ora o aponta como vilão, ora o trata como vítima das circunstâncias que permeiam a situação atual da Educação no Brasil.

Ficcion extrema: Deslizamientos en la realidad a traves de la relacion entre arte y literatura (Max Aub, Leonora Carrington y Enrique Vila-Matas)

Si el siglo XX creó una extendida conciencia sobre las variantes de la intertextualidad en la ficción literaria, hoy enfrentamos transformaciones en la naturaleza de la ficción y sus relaciones con otras formas discursivas y/o creativas como el arte, y con la misma realidad, que es posible designar con el concepto de ficción extrema. Desde "Don Quijote" o "Las meninas" hay incursiones en la metaficción y/o autorrefecividad. Pero a partir de las vanguardias modernistas y de modo creciente en los estertores de la postmodernidad nos abocamos a un singular tipo de hipertextualidad que desbordando lo literario se apropia de prácticas artísticas (o lo contrario) como recurso para la transposición de sus ficciones, no sólo de uno a otro campo, sino para su inserción en la realidad: la ficción extrema. ^ Max Aub (España 1903-México 1973), Leonora Carrington (Inglaterra 1917-México 2011) y Enrique Vila-Matas (España 1958), radicalizaron este tránsito o filtración de los imaginarios artísticos y literarios subvirtiendo las delimitaciones entre —pintor catalán Jusep Torres Campalans, junto con sus obras pictóricas, creadas como sombra o doble de Picasso. Así insertó su existencia en ciertos dominios del cubismo como un modo de meta-crítica artística. Carrington asumió un doble animal que transitó entre cuentos y cuadros y se inscribió en la memoria del surrealismo. Vila-Matas narró su "Historia abreviada de la literatura portátil" como un doble del espectro Marcel Duchamp —a su vez asaltado por otros— que reescribe la memoria del dadaísmo de tal modo que ha llegado a ser confundida con un ensayo. La revisión de las estrategias de la ficción extrema en estos autores junto con las de otros contemplados en el epilogo —Mario Bellatín, y los artistas Liliana Porter, Luis Camnitzer, José Guillermo Castillo, Ana Tisconia, Rubén Torres Llorca y Carlos Amorales— arroja nueva luz sobre sus obras, enriquece los estudios transatlánticos y revela la movilidad y multiplicación de la identidad y los deslizamientos de la ficción en la realidad como signos de tránsito a la altermodernidad.^

Método híbrido para detecção e diagnóstico de falhas baseado em resíduos

The detection and diagnosis of faults, ie., find out how , where and why failures occur is an important area of study since man came to be replaced by machines. However, no technique studied to date can solve definitively the problem. Differences in dynamic systems, whether linear, nonlinear, variant or invariant in time, with physical or analytical redundancy, hamper research in order to obtain a unique solution . In this paper, a technique for fault detection and diagnosis (FDD) will be presented in dynamic systems using state observers in conjunction with other tools in order to create a hybrid FDD. A modified state observer is used to create a residue that allows also the detection and diagnosis of faults. A bank of faults signatures will be created using statistical tools and finally an approach using mean squared error ( MSE ) will assist in the study of the behavior of fault diagnosis even in the presence of noise . This methodology is then applied to an educational plant with coupled tanks and other with industrial instrumentation to validate the system.

Avaliação de polimorfismos funcionais nos genes de reparo XRCC1, APEX1, XPD e XPF em carcinomas de células escamosas orais

Base excision repair (BER) and nucleotide excision repair (NER) pathways play critical role in maintaining genome integrity. Polymorphisms in BER and NER genes which modulate the DNA repair capacity may affect the susceptibility and prognosis of oral cancer. This study was conducted with genomic DNA from 92 patients with oral squamous cell carcinomas (OSCC) and 130 controls. The cases were followed up to explore the associations between BER and NER genes polymorphisms and the risk and prognosis of OSCC. Four single-nucleotide polymorphisms (SNPs) in XRCC1 (rs25487), APEX1 (rs1130409), XPD (rs13181) and XPF (rs1799797) genes were tested by polymerase chain reaction – quantitative real time method. The GraphPad Prism version 6.0.1 statistical software was applied for statistical analysis of association. Odds ratio (OR), hazard ratio (HR), and their 95 % confidence intervals (CIs) were calculated by logistic regression. Kaplan-Meier curve and Cox proportional hazard model were used for prognostic analysis. The presence of polymorphic variants in XRCC1, APEX1, XPD and XPF genes were not associated with an increased risk of OSCC. Gene-environment interactions with smoking were not significant for any polymorphism. The presence of polymorphic variants of the XPD gene in association with alcohol consumption conferred an increased risk of 1.86 (95% CI: 0.86 – 4.01, p=0.03) for OSCC. Only APEX1 was associated with decreased specific survival (HR 3.94, 95% CI: 1.31 – 11.88, p=0.01). These results suggest an interaction between polymorphic variants of the XPF gene and alcohol consumption. Additionally APEX1 may represent a prognostic marker for OSCC.

Estudo da resposta Th17 no transplante renal alogênico: contribuição do eixo quimiotático CCR6/CCL20 e dos polimorfismos gênicos em IL17A e IL17RA

Kidney transplantation is the best treatment for patients who have lost kidney function. Renal transplant patients require accurate immunosuppressive drugs to prevent rejection. In this process T helper cells of the immune system perform key role in the immune response to the graft, and recently the Th17 cells has been investigated by production of IL-17 potent proinflammatory cytokine whose role in the rejection has also been described. Increased of Th17 cell expression has an important association with the development of rejection in renal microenvironment, however the likely mechanism is not well understood. This study aimed to evaluate the Th17 response from the influence of the chemotactic axis CCR6/CCL20 and genetic variants in IL-17 and IL-17RA. We conducted a case-control study involving 148 patients transplanted at the University Hospital Onofre Lopes/UFRN in which assessed by immunohistochemistry protein expression of IL-17 and chemokines CCR6/CCL20 and by PCR-RFLP genetic variants in IL17A and IL17RA. Our results showed no influence of genetic polymorphisms on the outcome of the graft or the protein expression of IL-17. In renal graft microenvironment found several sources producing IL-17: tubular epithelial cells, glomerular cells, neutrophils and cell interstitial infiltration, in turn the expression of chemotactic axis CCR6/CCL20 was restricted to the tubular epithelium cells. There was a slight positive linear correlation between the presence of IL-17 and expression of chemotactic axis CCR6/CCL20 in the microenvironment of renal graft. Therefore, we believe that, combined with our results, further studies with increased "n" sample and greater control over the variables involved in obtaining the renal specimen, can determine more clearly the influence of chemotactic axis CCR6 / CCL20 and polymorphisms in cytokines related to Th17 profile on the control of this cell subtype response in rejection processes to renal allograft.

Síndrome de Guillain-Barré: epidemiologia, prognóstico e fatores de risco

Introduction. Guillain-Barré syndrome (GBS) is an immune-mediated polyneuropathy and the principal cause of acute neuromuscular paralysis. The most prominent GBS subtypes are: acute inflammatory demyelinating polyneuropathy (AIDP), acute motor axonal neuropathy (AMAN), acute motor-sensory axonal neuropathy (AMSAN) and Fisher syndrome (FS). Differences in geographical distribution of variants have been reported. In Brazil, there are few studies describing the characteristics of GBS, but none on the frequency of GBS variants and their clinical manifestations. Infection-induced aberrant immune response resulting from molecular mimicry and formation of cross-reacting antibodies, contribute to complement activation. Functional biallelic polymorphism in immunoglobulin receptors that influence the affinity of IgG subclasses and the type of immune response have been described, suggesting genetic susceptibility to developing disease. It remains unclear whether individuals carrying different FCGR alleles have differential risk for GBS and⁄or disease severity. The goals of this study were: (1) To characterize GBS and describe the clinical findings in a cohort of patients with GBS from the state of Rio Grande do Norte, Brazil; (2) to determine whether polymorphism in FCGR were associated with development of GBS, and (3) to tease out whether the global gene expression studies could be a tool to identify pathways and transcriptional networks which could be regulated and decrease the time of disease. Methods. Clinical and laboratory data for 149 cases of GBS diagnosed from 1994 to 2013 were analyzed. Genomic DNA and total RNA were extracted from whole blood. Antigangliosides antibodies were determined in the sera. In addition, we also assessed whether FCGR polymorphism are present in GBS (n=141) and blood donors (n=364), and global gene expressions were determined for 12 participants with GBS. Blood samples were collected at the diagnosis and post-recovery. Results. AIDP was the most frequent variant (81.8%) of GBS, followed by AMAN (14.7%) and AMSAN (3.3%). The incidence of GBS was 0.3 ⁄ 100,000 people for the state of Rio Grande do Norte and cases occurred at a younger age. GBS was preceded by infections, with the axonal variant associated with episodes of diarrhea (P = 0.025). Proximal weakness was more frequent in AIDP, and distal weakness predominant in the axonal variant. Compared to 42.4% of cases with AIDP (P<0.0001), 84.6% of cases with the axonal variant had nadir in <10 days. Individuals with the axonal variant took longer to recover deambulation (P<0.0001). The mortality of GBS was 5.3%. A worse outcome was related to an axonal variant (OR17.063; P=0.03) and time required to improve one point in the Hughes functional scale (OR 1.028; P=0.03). The FCGR genotypes and allele frequencies did not differ significantly between the patients with GBS and the controls (FCGR2A p=0.367 and FCGR3A p=0.2430). Global gene expression using RNAseq showed variation in transcript coding for protein isoforms during acute phase of disease. Conclusions. The annual incidence of GBS was 0.3 per 100,00 and there was no seasonal pattern. A predominance of the AIDP variant was seen, and the incidence of the disease decreased with age. The distribution of weakness is a function of the clinical variants, and individuals with the axonal variant had a poorer prognosis. Early diagnosis and variant identification leads to proper intervention decreasing in long-term morbidity. FCGR polymorphisms do not seem to influence susceptibility to GBS in this population. This study found deregulated genes and signs of transcriptional network alterations during the acute and recovery phases in GBS. Identification of pathways altered during disease might be target for immune regulation and with potential to ameliorate symptoms.

Proposta de válvula bypass para controle de velocidade de PIGs instrumentados: protótipo e simulação em bancada

In the Oil industry, oil and gas pipelines are commonly utilized to perform the transportation of production fluids to longer distances. The maintenance of the pipelines passes through the analysis of several tools, in which the most currently used are the pipelines inspection cells, popularly knowing as PIG. Among the variants existing in the market, the instrumented PIG has a significant relevance; acknowledging that through the numerous sensors existing in the equipment, it can detect faults or potential failure along the inspected line. Despite its versatility, the instrumented PIG suffers from speed variations, impairing the reading of sensors embedded in it. Considering that PIG moves depending on the speed of the production fluid, a way to control his speed is to control the flow of the fluid through the pressure control, reducing the flow rate of the produced flow, resulting in reduction of overall production the fluid in the ducts own or with the use of a restrictive element (valve) installed on it. The characteristic of the flow rate/pressure drop from restrictive elements of the orifice plate is deducted usually from the ideal energy equation (Bernoulli’s equation) and later, the losses are corrected normally through experimental tests. Thus, with the objective of controlling the fluids flow passing through the PIG, a valve shutter actuated by solenoid has been developed. This configuration allows an ease control and stabilization of the flow adjustment, with a consequent response in the pressure drops between upstream and downstream of the restriction. It was assembled a test bench for better definition of flow coefficients; composed by a duct with intern diameter of four inches, one set of shutters arranged in a plate and pressure gauges for checking the pressure drop in the test. The line was pressurized and based on the pressure drop it was possible to draw a curve able to characterize the flow coefficient of the control valve prototype and simulate in mockup the functioning, resulting in PIG speed reduction of approximately 68%.

Um controlador dual subótimo com fator de peso variável no tempo

This work concerns a refinement of a suboptimal dual controller for discrete time systems with stochastic parameters. The dual property means that the control signal is chosen so that estimation of the model parameters and regulation of the output signals are optimally balanced. The control signal is computed in such a way so as to minimize the variance of output around a reference value one step further, with the addition of terms in the loss function. The idea is add simple terms depending on the covariance matrix of the parameter estimates two steps ahead. An algorithm is used for the adaptive adjustment of the adjustable parameter lambda, for each step of the way. The actual performance of the proposed controller is evaluated through a Monte Carlo simulations method.

Os possessivos de segunda pessoa em cartas de leitores de jornais brasileiros dos séculos XIX e XX

Based on the theoretical and methodological presuppositions of the theory of language variation and change (cf. WEINREICH; LABOV; HERZOG, 2006 [1968]), it is described and analyzed in this article the process of variation/change concerning the second person possessive pronouns in letters from readers of Brazilian newspapers from the XIX and XX centuries. These letters feature a portrait of the Brazilian press from the South (Santa Catarina), Southeast (Rio de Janeiro) and Northeast (Bahia and Rio Grande do Norte) regions in each century and are part of the Project for Brazilian Portuguese History‘s (PHPB) printed common minimal corpus. The point of departure of this work is the idea that the use of variant forms of expressing second person possessive pronouns – teu and seu – results from the interaction characterizing the varied social roles performed by the letters‘ senders. Arranging communicative units, which gather elements/features denoting time and space, conditioned and determined by socio-historical and cultural aspects, the readers‘ letters, turn out to be a promising research field under the light of this paper. More specifically, In the row of presented results in studies about the pronominal system in the diachroneity of/in Brazilian Portuguese (PB) (FARACO, 2002; LORENGIAN-PENKAL, 2007; CALLOU; LOPES, 2003; LOPES; DUARTE, 2003; MENON, 2005; ARDUIN; COELHO, 2006; LOPES, 2009; MARCOTULIO, 2010), the results featured in here point at different usages of the possessives, noticing the coexistence of the forms teu/tua and seu/sua strongly conditioned by the socio-discursive nature of the readers‘ letters in the course of the centuries and through different regions.

Variabilidade genética de Leishmania spp. circulantes entre seres humanos e cães e infecção de flebotomíneos em áreas endêmicas para as leishmanioses no Rio Grande do Norte

Leishmania infantum is the main etiologic agent of visceral leishmaniasis in the New World. The pattern of distribution of leishmaniasis has changed substantially and has presented an emerging profile within the periphery of the Large Urban Centers. Leishmania infection can compromise skin, mucosa and viscera. Only 10% of the individuals infected develop the disease and 90% of human infection is asymptomatic. The main factors involved in the development of the disease are the host immune response, the vector’s species and the parasite’s genetic content. The sequencing of Leishmania isolated seeks to increase the understanding of the symptoms of individuals. The aim of this study was to evaluate the genetic diversity of circulating Leishmania strains among humans, and symptomatic and asymptomatic, and dogs from endemic areas of Rio Grande do Norte State and analyze sandflies from endemic areas for cutaneous and visceral disease. The genetic variability was evaluated by the use of markers hsp70 , ITS1 and a whole genome sequencing was also carried out. The amplified hsp70 and ITS1 of samples were analyzed and assembled using a Phred / Phrap package. The dendograms were constructed using the same methodology, but adding 500 bootstraps, followed by inferences on the relationships between Leishmania variants. The sequences of the 20 Brazilian isolates were mapped to the reference genome L. infantum JPCM5, using the Bowtie2 program and the identification of 36 contigs. The information of the valid SNPs were used in the PCA. SNPs were visualized by Geneious 7.1 and IGV. The genome annotations were transferred to their respective chromosomes and displayed on Geneious. The matching sequences of all chromosomes were aligned using Mauve. The phylogenetic trees were calculated according to maximum likelihood and JTT models. Sandflies were analyzed by PCR for the identification of Leishmania infection, a blood meal source and GAPDH sand fly. As a result, hsp70 and ITS1 were not capable of identifying genetic variability among human isolates from symptomatic and asymptomatic, and dogs. The complete sequencing of the 20 Brazilian isolates revealed a strong similarity between the circulating Leishmania strains in Rio Grande do Norte. The isolates collected in the city of Natal from humans and canines remained grouped in all analyzes, suggesting that there is genotypic and geographic proximity among the isolates. The isolated samples in the 1990s had a higher genotypic diversity when compared to freshly isolated samples. All isolates presented 36 chromosomes with variable ploidy among them, no correlation was found between the number of amastina genes copies, gp63, A2 and SSG with such clinic forms. In general, we did not find correlation between symptomatic and asymptomatic clinical forms and the gene content of the Brazilian isolates of Leishmania. 34,28% of the sandflies collected in the upper west region were L. longipalpis and the main sources of blood meal were humans, dogs and chickens.

Arte y Astronomía-Astrología de mediados del Quattrocento a Peruzzi y Rafael

Enlazando con el legado de la Antigüedad de Homero a Firmico Materno y el Planisferio Bianchini, se alude a Manilio clave en estas reflexiones sobre Astronomía-Astrología; asimismo quedan referenciadas las aportaciones y variantes medievales orientales y occidentales, hasta Pietro d’Abano en Padua. Tras unas apreciaciones respecto a Venecia como potencia editorial desde fines del siglo XV, y desde luego con referencia a Aldo Manuzio, son considerados varios ejemplos del Quattrocento, de Rimini a Florencia, con vértice en la corte de Ferrara, Borso d’Este, Cosmè Tura y la referencia expresa a Manilio en el Salone dei Mesi. El periplo concluye en Roma, con las contribuciones de Rafael y Peruzzi, en obras para los papas Julio II y León X, así como para el Magnífico Agostino Chigi.

Cuaderno de hule negro

El poeta nicaragüense Rubén Darío fue uno de los principales representantes del modernismo y uno de los escritores que han tenido mayor influencia en la literatura en lengua española de finales del siglo XIX y principios del XX. Su archivo personal, formado por más de 5.000 documentos, reúne materiales producidos entre los años 1893-1923 relativos a su actividad diplomática, a la literaria y a su vida personal. La tipología documental es muy variada: borradores, fotografías, cartas, notas manuscritas, postales, tarjetas de visita, testamentos, telegramas, recortes de prensa, oficios, facturas, menús, etc. Entre todos ellos podemos destacar el "cuaderno de hule negro" que contiene poemas autógrafos de Darío, dibujos infantiles y otros escritos relativos a su ámbito familiar más íntimo. Está inventariado dentro del Archivo con el nº 540, carpeta 6. Se trata de un cuaderno escolar, con tapas de hule, que llevó consigo Rubén Darío durante su viaje a Nicaragua de 1907 a 1908 y que trajo de regreso a España. Tanto las tapas de hule como las páginas acusan la acción del tiempo, así como la huella de otros usos, como el de servir de cuaderno de dibujo para su hijo Rubén Darío Sánchez "Güicho", ya de vuelta en el hogar, apreciándose dibujos infantiles, rayas y garabatos a lápiz en casi todas las páginas, incluso en la que contienen autógrafos de Darío. Faltan cuatro hojas al principio y las páginas han sido numeradas a posteriori. Las primeras 38 contienen una serie de composiciones poéticas autógrafas, completas e incompletas de Rubén, varios poemas editados, algunos de ellos con variantes entre las versiones autógrafas y las versiones impresas, tratándose de los primeros originales, y varios poemas y cinco estrofas de un poema inéditos. Destacan el "Poema de otoño" (páginas 1-11), incompleto, y el manuscrito original del poema "Canción otoñal" (páginas 13-14). Abriendo el cuaderno por el final (páginas 41-59) se observan páginas copiadas por Francisca Sánchez, en letra irregular, probablemente de un capítulo de la novela inédita de Darío "La isla del oro". Francisca fue la compañera del poeta desde 1899 y a ella la enseñaron a escribir el propio Darío y Amado Nervo. En la página 40 del cuaderno se observa una curiosa anotación de puño y letra de Darío con claves telegráficas para comunicarse Rubén y Francisca. Tras el fallecimiento de Rubén en 1916, Francisca Sánchez custodió el conjunto documental en un baúl en su hogar de Navalsaúz (Ávila) hasta 1956, cuando decidió donarlo al Ministerio Español de Educación Nacional. El archivo permaneció en la Facultad de Filología de la Universidad Complutense de Madrid hasta 2008. En esta fecha ingresó en la Biblioteca Histórica de la UCM, institución que alberga y da servicio público del Archivo actualmente
