Este trabajo tiene como objetivo investigar el tratamiento ofrecido al estudio de la lenguaje en la modalidad oral en clases de lengua portuguesa en los 3º y 4º ciclos del Nivel Fundamental a la luz de concepciones sociointeracionistas de lenguaje. Para tal, tomamos como referencia las contribuciones de Bakhtin (1992) Marcuschi (2005), Batista (2001), Antunes (2009), Bagno (2002), Suassuna (2009), Ramos (2002), Castilho (2000), Oliveira (2003), entre otros, como también tomamos como referencia los objetivos establecidos en los programas oficiales, entre los cuales están los PCN de lengua portuguesa, el PNLD y el regimiento escolar. El campo de pesquisa seleccionado fue una escuela pública de la ciudad de Parnamirim donde los datos fueran colectados en visitas, en las entrevistas grabadas con los sujetos y también durante las observaciones a las clases. Hecho estos procedimientos de coleta de datos se hizo su análisis que estuvo vinculada al referencial teórico. Los resultados de la pesquisa indican características en el tratamiento ofrecido al lenguaje oral que refleja, principalmente, una concepción de lengua y lenguaje adoptada por los profesores aún muy vinculada a las concepciones estructuralistas, sin lograr una práctica que contemple la oralidad como objeto de estudio

Examinaram-se a adesão, a germinação, a penetração e a colonização de larvas e ninfas de Rhipicephalus sanguineus por Metarhizium anisopliae, assim como as lesões infringidas pelo fungo nas respectivas fases do ciclo de vida do ácaro. Realizaram-se infecções experimentais em 11 grupos contendo 250 larvas e 11 grupos contendo 75 ninfas de R. sanguineus, por meio de banho, durante três minutos sob agitação manual, em suspensão contendo 10(8) conídios/ml do fungo. Nos grupos-controles, o banho foi realizado usando o veículo da suspensão. Larvas e ninfas foram processadas para um estudo histopatológico e de microscopia eletrônica de varredura nos seguintes tempos após a infecção: uma e 18 horas, e um, dois, três, quatro, cinco, seis, sete, nove e 11 dias. A germinação dos conídios ocorreu em até 18 horas pós-inoculação, e o fungo penetrou nas larvas e ninfas através do tegumento, dois e três dias após a infecção, respectivamente. Após penetração, o fungo invadiu o corpo das larvas e ninfas, promovendo uma colonização difusa, sem preferência aparente por tecidos específicos. Lesões significativas não foram observadas. A morte das larvas e ninfas ocorreu no terceiro e quarto dias pós-infecção, e a esporulação do patógeno sobre o cadáver foi iniciada no sexto dia pós-infecção.

The aim of this work is to analyse the tourism events and the performance of this segment from market as strategy in the combat of Natal's hotel seasonality, in the executives/managers's vision from this sector. Two searches were realized to turn available this study: Inicialy a bibliographic search involving the concepts associated with the tematic in question so that it arranges the embasament theoric-scientific and a survey from facts through the country search, where it was applicable in the establishments of work's population with the auxiliary from a formulary answered by a personal interview. The analyses techniques through facts were: estatistic descritive and Kolmogorov-smirnov test.Among the results found, it was verified that the main reasons alleged by the hotels to ingress in the segment from the events were the alinement from the competitive company, the diversification in the options in the sense of occupy the establishments during the period of low season and answer to the demand of market. Investigated the profile from the events occured in the Natal hotels referring to the port, public origin , kinds of events and frequency from their realizations, as well as , the capacity from these establishments to attend this segment.It was noticed that in spite of the hotels agree that the events are important estrategies to combat the seasonality, the establishments still suffer with the flutuation, what can be justified from the moment that it's considered that the events also behave from seasonal manner, having more concentration in certain periods from the year. It was evaluated that the main advantage noticed by the realization from the hotels's events is the utilization from alimentation and drinking services, surpassing the advantage from elevation of taxes occupation from the apartments

In the contemporary society, the language is presented in all social spaces and assumes many different purposes in order to meet the needs that emerge from each of these sphere. In traffic, this reality is not different. To guide vehicles, it is necessary to know, by means of reading artifacts, what the legislation establishes in what concerns the way to act in this domain. Thus, this works aims at describing the practices of literacy held in events of driver trainings and know the expectations generated by drivers/learners from this training. In theoretical terms, it anchors in Literacy Studies, comprehended here as social practices (BARTON; HAMILTON, 1998; KLEIMAN, 1995, 2008; MORTATTI, 2004; STREET, 1984; OLIVEIRA, 2008, 2010; ROJO, 2009; PAZ, 2008). Genre Theory (BRONCKART, 2004, 1999; OLIVEIRA, 2010) and in your multimodal instance (KRESS; VAN LEEUWEN, 1996; DIONÍSIO, 2006). In terms of methodology, it follows the bias of qualitative research, because of its ethnographic nature (BOGDAN; BIKLEN, 1994; MINAYO, 2010; CANÇADO, 1994; CHIZZOTTI, 2005). The research corpus was generated by reading the Brazilian Traffic Code, by observing the literacy events held in Drivers Training Centers of Natal, analysis of course books used in these events, plus questionnaires with open and closed questions and semistructured interviews. The collaborators are constituted of drivers in training, and instructors who work in this field. The analyses show significant contributions regarding the placement more committed of future drivers with the welfare and safety of those who use the public roads, from the practice or reading done during the traffic training. The contribution of this work lies in the possibility to expand the discussion about the language practice uses regarding the training for the traffic, more specifically, the training of drivers of vehicles

Pervasive applications use context provision middleware support as infrastructures to provide context information. Typically, those applications use communication publish/subscribe to eliminate the direct coupling between components and to allow the selective information dissemination based in the interests of the communicating elements. The use of composite events mechanisms together with such middlewares to aggregate individual low level events, originating from of heterogeneous sources, in high level context information relevant for the application. CES (Composite Event System) is a composite events mechanism that works simultaneously in cooperation with several context provision middlewares. With that integration, applications use CES to subscribe to composite events and CES, in turn, subscribes to the primitive events in the appropriate underlying middlewares and notifies the applications when the composed events happen. Furthermore, CES offers a language with a group of operators for the definition of composite events that also allows context information sharing

Este estudo foi desenvolvido com o objetivo de caracterizar as quedas de pacientes internados ocorridas em hospital terciário. Foram analisados 826 Boletins de Notificação de Eventos Adversos, de um período de 30 meses, que registraram 0,30 quedas por 1000 pacientes/dia. Quedas do leito foram mais frequentes (55%), com maior prevalência na enfermaria de neurologia. Maior frequência de quedas foi verificada no período noturno (63,7%), nos primeiros cinco dias da admissão (61,7%), nos pacientes de sexo masculino (57,5%) e na faixa etária maior de 60 anos (50%). Nos casos de quedas do leito, os diagnósticos relacionaram-se a doenças infecciosas e parasitárias (18,2%), doenças do sistema nervoso (18,2%) e doenças do aparelho circulatório (13,7%). Nas quedas da própria altura, os diagnósticos relacionaram-se a neoplasias (19,4%) e doenças do aparelho geniturinário (16,1%). A caracterização desses eventos adversos auxilia no reconhecimento dos grupos de maior risco e na elaboração de propostas preventivas.

This research arose from the interest on the investigation about urban expansion from Caicó. Since its creation as a village and its ascent to the condition of city, but especially , the occurred expansion from the 70s, when the local cotton economy begins to present signs of exhaustion. The central theme of this work consists on the importance of the geographical events and its relations with the phenomenon of the urban expansion from Caicó that served us as empirical basis. In relation to the events, that appear as elements of analysis on the works from the Professor Milton Santos, especially on the book Nature of Space , they appear as a kind of urban extensors energizing the areas where are installed. Understood by us as a vehicle of one or more possibilities, according to Santos, (1999) we listed some events occurred in the caicoense urbs a nd we divided them into principal and derivative ones, such events implemented from their structures, forms and functions, through processes that resulted and still continue to result the enlargement of the caicoense urban perimeter , densifications enough important for this urban expansion. The technical periods of cattle raising , cotton, as well as the tertiary city and its connections with the role of fast men, as well as slow men is also important aspect in the body of this work. It is still pointed out the inequalities and the coexistences that are generated on the basis of these connections and finally we discussed the positive and negative consequences elapsed from the phenomenon of the urban expansion

Há poucos dados sistematizados sobre eventos adversos da vacina contra influenza no Brasil. Este trabalho visou identificar estes eventos em população acima de 60 anos que compareceu à Campanha Nacional de Vacinação do Idoso, em Distrito de Campinas, SP, em 2000. Foi realizada entrevista para relato de sintomas gerais e locais, com nexo temporal após a aplicação do imunobiológico, em amostra aleatória sistemática da população (n=206). Registraram-se 20,38% (IC 14,87-25,88) dos indivíduos com um ou mais sintomas, sendo a dor no local da vacina, a mais freqüente 12,6% (IC 8,09-17,15). Ajustou-se um modelo de regressão logística múltipla, tendo como variável dependente, a ocorrência de pelo menos um evento adverso. A variável independente que se mostrou associada às reações adversas foi o sexo (feminino) (OR=5,89 e IC 2,08-16,68). Os achados deste estudo reafirmam a pequena reatogenicidade da vacina contra a influenza.

The beachs of Santos are situated in Santos Bay, central portion of paulista coast, in São Paulo state. This beachs are frequently affected by cold fronts with winds and currents from the South. These fronts are responsible for the removal and transport of sediments (sand) in Santos beaches. In order to quantify this sedimentation the channels of Santos were analysed, due to their function as box colectors of sediments during storm events. The channels are filled by sands, which volume in channels 1 to 6 was estimated, by using the length, width and height of sand sedimented in the channels, in the event of 22-27 april 2005. The chanels 2, 3 and 1 presented the larger volumes of sands, confirming that the central and SW portion of the beaches of Santos present higher levels of sedimentation or re-sedimentation. That is due to the transport by ocean waves and currents and currents from the Channel of the Port of Santos. This central portion suffer invasion of marine water over street and buildings, caracterizated of geological rise area.

Sickle cell disease is an inflammatory condition with a pathophysiology that involves vaso-occlusive episodes. Mutations of the methylenetetrahydrofolate reductase (MTHFR) and cystathionine beta-synthase (CBS) genes are risk factors for vascular disease. Due to the importance of identifying risk factors for vaso-occlusive events in sickle cell patients, we investigated the frequencies of the C677T and 844ins68 mutations of the MTHFR and CBS genes, respectively. Three hundred patients with Hb SS, HB SC and HbS/Beta thalassemia, from Brasília, Goiânia, Rio de Janeiro, São Jose do Rio Preto and São Paulo were evaluated. Samples of 5 mL of venous blood were collected in EDTA after informed consent was received from patients. Classical diagnostic methods were used to confirm the hemoglobin phenotypes. The hemoglobin genotypes and polymorphisms studied were evaluated by Restriction Fragment Length Polymorphism and Allele Specific amplification. The results showed that 93 patients (31.00%) were heterozygous and 13 (4.33%) homozygous for the C677T mutation and 90 were heterozygotes (30.00%) and 8 homozygous (2.66%) for the 844ins68 mutation, both with significant differences for genotype frequency between the localities. The allelic frequencies are in Hardy-Weinberg equilibrium for both polymorphisms. The frequency of mutations was significant and the presence of related vaso-occlusive events was more common in patients with Hb SS (p = 0007). The 844ins68 mutation was approximately three times more frequent in patients with vaso-occlusive complications (p = 0011). The C677T mutation did not prove to be associated with risk of vaso-occlusive events (p = 0.193). A C677T-844ins68 interaction occurred in 12.08% of the patients, doubling the risk of vaso-occlusive manifestations. The frequencies of the polymorphisms are consistent with those expected in the Brazilian population. The presence of the 844ins68 mutation of the CBS gene proved to be a potential risk factor for vaso-occlusive events in sickle cell patients.
