Estimativas, variabilidade e análise de tendência da evapotranspiração de referência em perímetros irrigados, no semiárido do nordeste brasileiro

The variability / climate change has generated great concern worldwide, is one of the major issues as global warming, which can is affecting the availability of water resources in irrigated perimeters. In the semiarid region of Northeastern Brazil it is known that there is a predominance of drought, but it is not enough known about trends in climate series of joint water loss by evaporation and transpiration (evapotranspiration). Therefore, this study aimed to analyze whether there is increase and / or decrease evidence in the regime of reference evapotranspiration (ETo), for the monthly, annual and interdecadal scales in irrigated polo towns of Juazeiro, BA (9 ° 24'S, 40 ° 26'W and 375,5m) and Petrolina, PE (09 ° 09'S, 40 ° 22'W and 376m), which is the main analysis objective. The daily meteorological data were provided by EMBRAPA Semiárido for the period from 01.01.1976 to 31.12.2014, estimated the daily ETo using the standard method of Penman-Monteith (EToPM) parameterized by Smith (1991). Other methods of more simplified estimatives were calculated and compared to EToPM, as the ones following: Solar Radiation (EToRS), Linacre (EToL), Hargreaves and Samani (EToHS) and the method of Class A pan (EToTCA). The main statistical analysis were non-parametric tests of homogeneity (Run), trend (Mann-kendall), magnitude of the trend (Sen) and early trend detection (Mann-Whitney). The statistical significance adopted was 5 and / or 1%. The Analysis of Variance - ANOVA was used to detect if there is a significant difference in mean interdecadal mean. For comparison between the methods of ETo, it were used the correlation test (r), the Student t test and Tukey levels of 5% significance. Finally, statistics Willmott et al. (1985) statistics was used to evaluate the concordance index and performance of simplified methods compared to the standard method. It obtained as main results that there was a decrease in the time series of EToPM in irrigated areas of Juazeiro, BA and Petrolina, PE, significant respectively at 1 and 5%, with an annual magnitude of -14.5 mm (Juazeiro) and -7.7 mm (Petrolina) and early trend in 1996. The methods which had better for better agreement with EToPM were EToRS with very good performance, in both locations, followed by the method of EToL with good performance (Juazeiro) and median (Petrolina). EToHS had the worst performance (bad) for both locations. It is suggested that this decrease of EToPM can be associated with the increase in irrigated agricultural areas and the construction of Sobradinho lake upstream of the perimeters.

Intervalos de referência do zinco sérico e sua relação com os indicadores dietéticos, funcionais e bioquímicos em crianças saudáveis

Objective: To determine the zinc status and reference intervals for serum zinc concentration considering dietary, functional, and biochemical indicators in healthy children in the Brazilian Northeast. Methods: The study included 131 healthy children, 72 girls and 59 boys, between 6-9 years old. Anthropometric assessment was made by BMI/age; dietary assessment by prospective 3-day food register, and evaluation of total proteins was performed. Zinc in serum samples were analyzed in triplicate in the same assay flame using atomic absorption spectrophotometry. Results: All subjects were eutrophic according to BMI/age classification. With respect to dietary assessment, only the intake of fiber and calcium were below the recommendations by age and gender. Biochemical parameters were all within the normal reference range. Reference intervals for basal serum zinc concentration 0.70-1.14 μg/mL in boys, 0.73-1.17 μg/mL in girls, and 0.72-1.15 μg/mL in total population. Conclusions: This study presents pediatric reference intervals for serum zinc concentration, which are useful to establish the zinc status in the population or in specific groups.

Atuação de psicólogos em Centros de Referência de Assistência Social na região amazônica do Marajó

This study investigated the role of psychologists in Social Assistance Reference Centres in the Amazon region of Marajó, considering its specificities: extensive territory, spread population and presence of native communities. Eleven interviews were conducted in 10 out of the total 16 cities. There’s a context of fragile economies and poor housing; incomplete or disarticulated public services; bad working conditions. The activities are ad hoc or asystematic. Promising experiences bet on decentralized and intersectoral services. Experiences from other groups point to the importance of long-term work. We conclude that a powerful way of action is to strengthen the sociability that is characteristic of the native peoples, valuing their knowledge and developing their social protagonism.

Um coração que pulsa fora do corpo: imagens passionais nas cartas de Frida Kahlo

Entre los años 30 y 40 del siglo pasado, México vio surgir de las cenizas de la revolución mexicana, una figura singular. Frida Kahlo es descrita hasta la fecha de hoy, por el imaginario social – en sus pinturas, en sus fotografías – como una mujer que ha marcado una época y se ha convertido en un símbolo de luchas, y esto se extiende hasta la contemporaneidad. Se ha creado en torno a la pintora mexicana, varias imágenes sociales que se describen en el juego dialógico entre sus obras y sus interlocutores. Teniendo por referencia estas afirmaciones, la investigación aquí presentada ha tomado como procedimiento realizar un análisis de seis cartas escritas por Frida a sus interlocutores amados/amantes – tres hombres con los que estuvo involucrada, emocionalmente, durante diferentes períodos de su vida – y, como objetivo, hacer un mapeo de los ethé construidos por ella en enunciados en los cuales ella "pinta" verbalmente una imagen de sí misma que se revela en las opciones léxicas elegidas para hablar de amor, de traición, de amistad, de dolor y de su estar en el mundo. Por lo tanto, hemos refinado una imagen estética e ideológica de Frida Kahlo que se cubre de pasionalidades distintas y de diversos grados dialógicos. Hay, en el recorte temporal y axiológico que hicimos para esta investigación, una mujer de naturaleza amante y que transformó ese amor en el tono de sus enfrentamientos con los interlocutores con quienes estuvo involucrada emocionalmente. Nuestro análisis está anclado en los postulados teóricos del Análisis Dialógico del Discurso (ADD), cuyo teórico base es el filósofo ruso Mikhail Bakhtin (2003, 2009, 2013) – sobre todo cuando se trata de estilo – y en la teoría de la enunciación de Maingueneau (2008, 2005) y Charaudeau (2006) – en lo que se refiere al ethos discursivo. Esta investigación se inserta en el área de Lingüística Aplicada y tiene un enfoque cualitativo-interpretativo.

Referência e contra referência em saúde bucal: regulação do acesso aos centros de especialidades odontológicas

Objective Based on the system of reference and counter-reference and comprehensiveness in oral health care, we aimed to examine ways of refering users to Specialized Dental Care Centers (SDCC) and the interface between them and Primary Care. Methods This is a cross-sectional study carried out with users and dentists of SDCC in a metropolitan region of Northeast of Brazil. Analyses were descriptive, and the association test was done with chi-square. Results Six forms of entry to specialized service were identified: free demand (13.8 %) and reference by the Primary Care dentist (63.2 %) were most frequent. Users referred by the basic health unit dentist had more interest in making a counter-reference than the others (p<0.001, PR=4.65, 95 % CI: 2.74 to 7.91), while individuals without this referral had 1.49 times more difficulty obtaining care (95 % CI: 1.02 to 2.17). Referral procedures are a decisive factor for counter-references. However, the high demand for primary care services and the short supply these services can offer in the face of needs make SDCC performance difficult. Conclusion The analysis of oral health practices from the perspective of network modeling points to the service's need to establish protocols for regulation in a bid to improve access to and the quality of care provided.

Os operadores argumentativos como estratégia linguística e discursiva da argumentação na sentença judicial

We studied in this dissertation the argumentation in the court judgment, which goal was to identify, describe and explain the running of argumentative operators in the argumentative orientation of text and discourse built through the text of the judgment. We support our research in the constructs adopted for the ATD – (Textual Analysis of the Discourses) - Adam (2011), in the studies about the Aristotle’s Rhetoric (1959) and Perelman and Olbrechts-Tyteca (1996) and other works such as of the Alves (2005), Capez (2008), Charaudeau (2012), Keller and Bastos (2015), Koch (2009; 2011), Rodrigues, Silva Neto and Passeggi (2010), Trubilhano and Henriques (2013). In a methodological way, we made use of deductive-inductive method, because we analyzed the argumentation in an "unknown" text - particular case - based on a theory already known (about language, text and argumentation). About the nature and objectives, our search was characterized as qualitatively and as an explanatory and descriptive investigation, with technical procedures of documental collection of Bibliographic Search. As corpus, we use a court judgment of character condemnatory, issued on September 10, 2014 and taken from the online site of the Federal Court of Rio Grande do Norte (JFRN). The results revealed that the argumentative operators exercised decisive roles in the organization of argumentative strategies of the text and the speech , guiding the announcer to the Desired conclusion by the enunciator. It was also possible to conclude that the use of argumentative operators allowed syllogistic constructions in the form of presentation of the arguments and in the construction of argumentation. In addition, operators like "but", "until", "already", "although" etc. helped to identify in the data's analysis the point of view (PoV) of the enunciator, the expectation break about the previous enunciate and / or the value scale given to the argument. Finally, with the use of argumentative operators the enunciator introduced arguments able to demonstrate/justify a thesis and refute an opposing thesis towards a conclusion sought by the own enunciator.

Hepatite C crônica em serviço de referência no nordeste do Brasil: um estudo retrospectivo de dezoito anos de acompanhamento

Chronic Hepatitis C is the leading cause of chronic liver disease in advanced final stage of hepatocellular carcinoma (HCC) and of death related to liver disease. Evolves progressively in time 20-30 years. Evolutionary rates vary depending on factors virus, host and behavior. This study evaluated the impact of hepatitis C on the lives of patients treated at a referral service in Hepatology of the University Hospital Onofre Lopes - Liver Study Group - from May 1995 to December 2013. A retrospective evaluation was performed on 10,304 records, in order to build a cohort of patients with hepatitis C, in which all individuals had their diagnosis confirmed by gold standard molecular biological test. Data were obtained directly from patient charts and recorded in an Excel spreadsheet, previously built, following an elaborate encoding with the study variables, which constitute individual data and prognostic factors defined in the literature in the progression of chronic hepatitis C. The Research Ethics Committee approved the project. The results were statistically analyzed with the Chi-square test and Fisher's exact used to verify the association between variable for the multivariate analysis, we used the Binomial Logistic regression method. For both tests, it was assumed significance p < 0.05 and 95%. The results showed that the prevalence of chronic hepatitis C in NEF was 4.96 %. The prevalence of cirrhosis due to hepatitis C was 13.7%. The prevalence of diabetes in patients with Hepatitis C was 8.78 % and diabetes in cirrhotic patients with hepatitis C 38.0 %. The prevalence of HCC was 5.45%. The clinical follow-up discontinuation rates were 67.5 %. The mortality in confirmed cases without cirrhosis was 4.10% and 32.1% in cirrhotic patients. The factors associated with the development of cirrhosis were genotype 1 (p = 0.0015) and bilirubin > 1.3 mg % (p = 0.0017). Factors associated with mortality were age over 35 years, abandon treatment, diabetes, insulin use, AST> 60 IU, ALT> 60 IU, high total bilirubin, extended TAP, INR high, low albumin, treatment withdrawal, cirrhosis and hepatocarcinoma. The occurrence of diabetes mellitus increased mortality of patients with hepatitis C in 6 times. Variables associated with the diagnosis of cirrhosis by us were blood donor (odds ratio 0.24, p = 0.044) and professional athlete (odds ratio 0.18, p = 0.35). It is reasonable to consider a revaluation in screening models for CHC currently proposed. The condition of cirrhosis and diabetes modifies the clinical course of patients with chronical hepatitis C, making it a disease more mortality. However, being a blood donor or professional athlete is a protective factor that reduces the risk of cirrhosis, independent of alcohol consumption. Public policies to better efficient access, hosting and resolution are needed for this population.

A noção de relação na teoria linguística de Ferdinand de Saussure

Our work aims at investigating the notion of relation in Ferdinand de Saussure’s linguistic reflections. As we observe his theoretical production, we see this notion was amply worked in the elaboration of other concepts of his, for example, language, signe, value, arbitrariness, among others. However, beyond the capacity of the notion of relation to produce other concepts, the way it was conceived and the theoretical space it was placed allowed Saussure to break through the essentially historical-comparative studies of the epoch, what made a new way of thinking language to have its starting point. Taking it into account, firstly, by reading the work of Herman Paul, the one who represents the neogrammarians in our text, we examine in which way Saussure is distant from his contemporary linguistics when he distinguishes the linguistic relations and give them a new status in his investigation. Secondly, we study how the notion of relation has it own place in Saussure’s theoretical process of thinking the fundamentals which later would be considered the milestone for Modern Linguistics. For that, we analyse one of his manuscripts, Notes pour un livre sur la linguistique générale, and the Course in General Linguistics. The first is composed by sketches which would become a book, as Saussure promised in a letter to Meillet; and the latter contains the principals for the science of Linguistics. So we aim at researching how the notion of relation is treated in this corpus in order to see the way it is conceived both in the particular production of a manuscript written by Saussure itself and the book which was published and considered the turning point for Linguistics.

A noção de sistema na fundação da linguística moderna

This work is intended to investigate the saussurian notion of system. Such a notion is fundamental to Ferdinand de Saussure's theorization, since it composes the definition of "langue", as he thought it. This definition was crucial to the delimitation of linguistics' specific object of study, which granted its place among modern sciences. However, the notion of system was not created by Saussure. Not only in Linguistics, but also in other areas, this notion appeared in very ancient studies, mingling with the establishment of man in society and the development of their economic and organizational activities. Specifically, in the context of language studies, the system consists in a notion that composed the work of the first grammarians in the West, in ancient Greece. Moreover, this notion was also used afterwards, in the synonymy studies and in the comparative analysis of languages, developed by scholars of the nineteenth century. Nevertheless, although Saussure had had his formation in Leipzig and Berlim, amid comparatists studies, his notion of system is an innovation, while is also continuing. In light of this, we aim to highlight the aspects of the saussurian notion of system that allow the establishment of a relationship of continuity and rupture with other conceptions of system. For that, we will investigate four Saussure authored documents: the « Cours de linguistique générale », the « Mémoire sur le système primitif des voyelles dans les langues indo-européennes », and the two sets of manuscripts « De l'essence double du langage » and « Notes pour le cours III ».

Valores de referência de parâmetros acústicos para a voz normal no português europeu

O presente estudo tem como objetivo a caraterização acústica da voz normal para os falantes do Português Europeu, em termos de frequência fundamental, jitter, shimmer e relação sinal-ruído. São também analisadas as caraterísticas individuais que possam ter influência sobre a qualidade vocal, nomeadamente idade, género, índice de massa corporal, hábitos tabágicos e uso da voz no canto. Para tal, foram recolhidas amostras de fala de 363 indivíduos com uma voz avaliada como normal: 113 homens e 250 mulheres com idades compreendidas entre os 18 e os 91 anos. Amostras da produção sustentada da vogal /a/ foram analisadas acusticamente com o programa Praat, tendo sido extraídos os valores da média, mediana e desvio-padrão da frequência fundamental, jitter (ppq5), shimmer (apq11) e relação sinal-ruído. Os resultados obtidos apontam no sentido do género e a idade do indivíduo serem os fatores que maior influência exercem na voz, sendo que ambos os géneros apresentam um declínio da qualidade vocal ao longo da vida. As mulheres, globalmente, apresentam valores de frequência fundamental de 193,4±28,5 Hz (média ± desvio padrão da média), significativamente mais elevados que os homens, com valores de 120,7±22,3 Hz. Em termos de jitter, as mulheres obtiveram valores de 0,214±0,126 %, significativamente mais reduzidos que os 0,247±0,190 % obtidos para os homens. O shimmer não apresentou diferenças significativas entre géneros, sendo que os valores apresentados foram de 5,403±2,652 % para homens e 5,174±2,696 % para as mulheres. Relativamente à relação sinal-ruído, foram obtidos valores significativamente mais elevados nas mulheres, com 17,335±3,958 dB, tendo-se obtido para os homens 16,315±3,267 dB. Não foi encontrado um efeito significativo do índice de massa corporal, hábitos tabágicos e uso da voz no canto. Este trabalho disponibiliza novos dados para que a avaliação da voz em contexto clínico seja mais objetiva e eficaz.
