A concep??o de "movimento" em Lettres portugaises: novo momento na representa??o da subjetividade ocidental
Barros, André Luiz;
Alea : Estudos Neolatinos , 2006, DOI: 10.1590/S1517-106X2006000200004
Abstract: the text is a search about the use of the word mouvement (in french) in the novel lettres portugaises (1669). the analysis of the incidences of the word (one time in each one of the five letters) helps us to focus in a determined phase of the development of a new conception of the subjectivity in western culture. some senses of mouvement are compared to the aristotelian, the stoic and medieval senses of "passion" (pathos) (auerbach). entries of mouvement and émotion in two editions of the dicctionnaire de l'académie fran?oise (1694-1740) helps us to broaden the comprehension of the semantics of mouvement - and émotion, as one of its derivatives - in the cited novel as to clarify the constitution of the narrative of the variations of intimacy in our culture.

Abstract: it is essential to understand that not all smokers are equal, and that certain smokers need to be "won" as "potential clients" of an intervention program aimed at addressing their specific needs. thus, the objective of the article was to compare the profile of smokers recruited for a smoking cessation clinical trial with that of the general smoking population in the city of rio de janeiro, in the years 2002-2003. heterogeneities observed may indicate the need for adopting different recruitment strategies, associated with the existing interventions, to encourage as many and as diverse eligible individuals as possible.

Linguagem em (Dis)curso , 2006,
Abstract: Este trabalho relata um estudo da estrutura genérica e do léxico de reportagens veiculadas em um jornal produzido por uma cooperativa agropecuária do estado de Santa Catarina. O corpus da pesquisa foi constituído de 3 exemplares do jornal. Para sua análise, foi utilizado como referencial teórico Bakhtin (1992), Bazerman (2005) e Bonini (2003). Os resultados indicam que o jornal privilegia o gênero reportagem, que pode ser dividido em 7 categorias temáticas. Entre elas está a categoria “História de vida”, cujos movimentos retóricos e léxico demonstram que sua configura o está atrelada ao contexto em que é produzida e à fun o que ele cumpre no processo comunicativo.
Heterogeneous catalysts for use in the production of Biodiesel
Kamila Colombo,António André Chivanga Barros
Evidência : Ciência e Biotecnologia - Interdisciplinar , 2009,
Abstract: The search for cleaner fuels has resulted in the development of research for the processing of fats and oils, composed mainly of fatty acids with high energy and capable of conversion into esters (biodiesel) by transesterification or esterification reactions inhomogeneous catalysis, heterogeneous enzymatic or supercritical. The homogeneous transesterification is the most widely used, however the products obtained concentrated high levels of impurities, why are complemented secondary purification procedures such as liquid-liquid extraction and simple distillation, processes that enhance the generation of waste. The problems identified with the use of transesterification with homogeneous catalysis can be minimized by transesterification with heterogeneous catalysis that seeks to improve the effectiveness of biodiesel production. Thus, studies were conducted with heterogeneous catalysis transesterificationin a laboratory scale reactor, jacketed, with agitation system, temperature controlled and sealed to prevent the diffusion ofreagents to the environment. The heterogeneous catalyst used in these studies was developed by dissolution of potassium hydroxidein water and subsequent impregnation of aqueous solution, formed in clay and subsequent calcination. Thecatalyst was integrated in the reactor and added the necessary reagents for the production of biodiesel. Throughout the execution ofexperiments, controlling the process parameters such as reaction time, temperature and degree of agitation. The products obtainedwere evaluated and calculated the degree of conversion of fat into fatty acid esters and final concentration of esters.

Abstract: Introduction: Currently it is very common that the search for diagnosis and treatment for curing diseases can cause vertigo or dizziness. Objective: This study sought to characterize the profile of patients seen in the clinic for vestibular rehabilitation in a tertiary hospital in the last 10 years. Methods: Survey questionnaires of patients with dizziness. Results: The prevalence of treated subjects was female 65.3% (N = 439). The average age was 54.9 years old. Dizziness type roundabout was more prevalent 33.04% (N = 222). Tinnitus occurred in 58.33% of the population. The time of most observed dizziness was less than 5 years 70.68% (N = 475). Neurovegetative symptoms appeared in 63.98% (N = 430) of the population. The bilateral normal hearing was more standard 35.26% (N = 237). The topographic diagnosis of peripheral origin was the most usual 65.47% (N = 440). Conclusion: The peripheral otoneurologic involvement was more prevalent in this population, affecting more women at an average age of 54.9 years old. The most prevalent symptoms were vertigo, nausea, tachycardia, sweating, vomiting and tinnitus, characterizing the peripheral vestibular impairment. The time of dizziness was less than five years. Audiological standard normal curve was predominant and the symptom of tinnitus was the most reported. The most prevalent comorbidity was Hypertension.
Can mothers rely on the Brazilian health system for their deliveries? An assessment of use of the public system and out-of-pocket expenditure in the 2004 Pelotas Birth Cohort Study, Brazil
Aluísio JD Barros, Iná S Santos, Andréa D Bertoldi
BMC Health Services Research , 2008, DOI: 10.1186/1472-6963-8-57
Abstract: All deliveries occurring in the city of Pelotas, Brazil, during 2004, were recruited for a birth cohort study. All mothers were interviewed just after birth and three months later. Comprehensive data on the pregnancy, delivery, birth conditions and newborn health were collected, along with detailed information on expenses related to the delivery.The majority of the deliveries (81%) were financed by the public health system, a proportion that increased to more than 95% among the 40% poorest mothers. Less than 1% of these mothers reported some out-of-pocket expenditure. Even among those mothers covered by a private health plan, nearly 50% of births were financed by the SUS. Among the 20% richest, a third of the deliveries were paid by the SUS, 50% by private health plans and 17% by direct payment.The public health system offered services in quantity and quality enough to attract even beneficiaries of private health plans and spared mothers from the poorest strata of the population of practically any expense.Health costs in low and middle income countries can be an important source of expenditure and it has been shown that they can consume a high proportion of family income, up to catastrophic proportions. Brazil was identified as one of the countries with the highest proportion of households suffering from catastrophic health expenditure in a study comparing 59 countries[1]. This study showed that 10% of Brazilian households spent more than 40% of their capacity to pay (as catastrophic expenditure was defined), compared to 6% in Argentina and Colombia, 1.5% in Mexico, 0.5% in the US and practically zero in France and the UK. The only country with a similar result was Vietnam. Such a result is surprising given that Brazil offers comprehensive and free health services to all citizens through its national health system, the SUS (acronym for what could be translated into English as Unified Health System).The SUS was created in 1988, within the new Constitution, to offer f

Abstract: composition and diversity of medium and large size mammals in the cerrado of central brazil. studies about medium- and large sized mammals (> 1.0 kg) in disturbed areas in the cerrado showed that many species are adapted to anthropogenic environments. we investigated the structure of mammals assemblages in an area of 92,000 ha located in southwest of bahia and covered by plantations of pinus spp., soybeans and conserved strips of cerrado sensu stricto. the mammals were recorded in nine sampling campaigns of 12 days between january/2008 and may/2009 in diurnal and nocturnal transects that varied 5-15 km in length per campaigns totaling 3,600 km traveled/period. in this area 29 species were recorded, 23 through the line transect and others outside transect by indirect observation, capture and previous records. the mammal community consists mostly of representatives of the carnivora (41.4%) and omnivore species (36.7%). the only endemic species of cerrado recorded in the area was hoary fox, lycalopex vetulus. only 13.6% of species were present in all sampling (ozotoceros bezoarticus, pecari tajacu and tolypeutes tricinctus) and seven of which correspond to 91.73% of the records made. the species that had largest number of records (23.76%) is three-banded armadillo (t. tricinctus), probably this area holds the largest population of this endangered species in biome, highlighting the importance of avoiding areas of native vegetation are replaced by monocultures and reforestation. many of the species recorded are generalists in habitat use and widely distributed throughout the biome, occurring even in disturbed habitats. the maintaining of observed diversity in this area is due to its large size and the mosaic of environments that provide a greater variety and diversity of resources such as shelter and food, allowing also the presence of species with low densities and specialists in the diet and habitat.

Abstract: to study the utilization and access to dental services in brazil, and assess differentials across socioeconomic strata, data from the pesquisa nacional por amostragem de domicílios, 1998 (pnad/ibge), was used. the analysis, adjusted for the sampling design, showed a low level of utilization of dental services. among children 0-6 years of age, 77% had never seen a dentist, and among adults 20-49 years, 4%. in the latter group, the proportion of people that had never been to the dentist in the poorest 20% was 16 times higher than in the richest 20%. the proportion of people visiting a dentist in the year before the interview was greatest in the group 0-6 years of age, rich children presenting a prevalence 5 times higher than the poor ones. about 4% of those who sought dental care did not get it. the proportion was 8% among the poorest compared to 1% among the richest. most of the attendances (68%) was paid by the national health system among the poorest, while 63% of them were directly paid by the richest. great inequalities were found in the access and utilization of dental services, maximal exactly among the groups showing smaller access or utilization. the participation of the national health system in dental care is much lower than in medical care.
Efeito do Nb na cinética de revenimento de a?os de baixo carbono

Abstract: the effect of temperature and time on tempering kinetics was studied by using a low carbon steel microalloyed with nb (0,031) and another steel with a similar chemical composition, however without nb. after determining the vickers hardness values, the kinetics law of tempering was studied by the jonhson-mehl-avrami equation using a variation of temperatures and time for both steels. the hardness of the steel without nb did not change with the tempering time at 600oc and tended to saturate at high tempering times, for the different tempering temperatures used. for the tempering temperatures of 500 and 600oc, the steel with nb has a greater tempering resistance and this effect is associated to the precipitation of very fine nbc particles dispersed in ferrite matrix. the activation energy of the tempering transformation of the steel without nb is 130kj/mol and it could be inferred that the mechanism that controls the tempering kinetics of this steel is the interstitial diffusion of carbon in the ferrite. in the steel with nb the activation energy is 180kj/mol and the mechanism that controls the tempering kinetics is the nb diffusion in the ferrite.
