Diagnóstico médico por meio de relações Fuzzy: Dengue, Chikungunya ou Zika
(Universidade Federal de São Carlos, 2016-07-07) Marins, Lazaro Rodrigo de; Peixoto, Magda da Silva; https://lattes.cnpq.br/0413910306376054; https://lattes.cnpq.br/0869905967271911
This research aims to use the fuzzy relations to diagnose patients infected with the virus transmitted by the mosquito Aedes aegypti, which can be diagnosed with dengue, chikungunya or zika. For this we use fuzzy relational equations to propose a model of medical diagnosis. The basic idea is to relate the symptoms or signs of patients with these three diseases. First we studied basic concepts of Fuzzy Sets Theory through definitions, theorems and examples.
Diversidade genética de Euphractus sexcinctus (Linnaeus, 1758) em áreas de Cerrado e Pantanal
(Universidade Federal de São Carlos, 2016-07-07) Fischer, Eliana Michelle Paviotti; Desbiez, Arnaud Léonard Jean; https://lattes.cnpq.br/1343726040328032; Galetti Júnior, Pedro Manoel; https://lattes.cnpq.br/7398754661670478; https://lattes.cnpq.br/5978732027340421
Euphractus sexcinctus is a species of armadillo endemic to the South American continent, that has wide distribution and occurs in all Brazilian biomes. Although generalist, with some tolerance to environmental changes, the species is very threatened by anthropogenic pressures, mainly by roadkill. Therefore, this study aimed to provide genetic information for the species, increasing the understanding of the distribution of genetic diversity and its population genetic structure. To access the genetic diversity of the species, its complete genome was sequenced by next generation sequencing. From the sequencing data, the complete mitochondrial genome was assembled. The mitogenoma was considered as subspecies level: Euphractus sexcinctus flavimanus. Besides mitogenoma nuclear microsatellites markers were developed. These microsatellites were used to evaluate the distribution of genetic diversity of the species in areas of Cerrado and Pantanal. Molecular markers were used to identify the sex of the animals, since this identification was not performed during collection. The possibility of molecular sexing in armadillos can be useful, especially when studying carcasses. The data for mitochondrial genome of E. s. flavimanus showed differences, mainly in the control region (D-loop) in comparison to the mitochondrial genome of E. sexcinctus recently sequenced. Regarding the genetic diversity rates, high values were observed for the species in all sampled areas, which is expected to not endangered species. The Bayesian analysis and the molecular variance (AMOVA) analysis exposed a panmitic population of E. sexcinctus in part of the Mato Grosso do Sul, including areas of Cerrado and Pantanal. This fact should not discourage, however, conservation measures for the species, as thought he factorial correspondence analysis (FCA) showed that individuals in some areas barely overlap. In addition, the FST calculations indicated a significant, but very low, structuraction between individuals of cerrado and Pantanal. Molecular sexing showed males are more run dwon than females in two large sampled portions of the BR262. Data on roadkill showed several hotsposts roadkill. This data is useful for taking mitigating measures. However, more detailed data about the surrounding landscape become necessary to better understand the distribution of roadkill on highways sampled and ecology of this species of armadillo.
A imagem docente na novela Carrossel apresentada na Argentina, no México e no Brasil : a vocação, o magistério e a indústria cultural
(Universidade Federal de São Carlos, 2016-07-07) Valentim, Lucy Mary Soares; Zuin, Antônio Álvaro Soares; https://lattes.cnpq.br/5543562307373287; https://lattes.cnpq.br/6385075288522018
La imagen del maestro presentado en la pantalla a través de películas y novelas tienen un papel importante en la formación y el establecimiento de nuestra subjetividad. Este hallazgo despertó en mí el deseo de analizar la imagen del maestro Helena en carrusel novela. La primera versión de la telenovela bajo el título Jacinta Pichimahuida la maestra que si el Ovida, se estableció en Argentina en 1960 por Abel Santa Cruz. Antes de eso, sin embargo, entre 1938-1940, el autor publicó en la revista Patoruzú algunos cuentos sobre las aventuras de un maestro con sus alumnos en el aula o más. El éxito de las historias publicadas, despertó la adaptación a los medios electrónicos en forma de drama de la radio en 1964 y la serie de televisión en 1966. En 1980 la cadena de televisión Televisa en México compraron los derechos de la trama y producido con la misma autor, telenovela Carrusel. En 1992 se emitió la cuarta versión de la novela, emitir por satélite en toda América Latina, con el título Viva los Niños. En Brasil, la versión de la telenovela mexicana fue transmitido por el Sistema Brasileño de Televisión (SBT), entre 1991 y 1996. En 2012, el SBT produjo una nueva versión de la versión mexicana con actores brasileños. La imagen de maestro ha sido presentada como una princesa o un hada de hoy y se observa en las versiones de la novela transmitida en los tres países. Lo que llamó nuestra atención para la investigación fue el uso de la imagen por la industria cultural. En concreto, en la versión brasileña, se observó que el maestro Helena es la realización del maestro ideal, atento, da la bienvenida a los estudiantes y padres con simpatía y aprecio, visitan a las familias, resolver problemas, se reúne impotente, decepcionado, enfermo, en deuda. Siempre tiene palabras de consuelo, ánimo, ánimo. Además de estos atributos, la imagen es de una mujer joven y bella se presenta como una princesa de los tiempos modernos. El estudio trata de comprender cómo esta imagen trae la información bueno o malo el maestro que proporciona un conocimiento distorsionada de la realidad, mostrando una falsa idea del maestro, la escuela y los estudiantes, con la enseñanza como vocación por encima de la formación. El método utilizado para la literatura de investigación se busca autores de la Teoría Crítica de la Sociedad, para entender el renacimiento del concepto de industria cultural por el maestro novela carrusel de imágenes; estudios en Theodor Adorno, particularmente en su análisis del pensamiento crítico para la práctica de la enseñanza; autores que apoyaron el concepto de vocación; autores que contribuyeron a la comprensión de la novela del carrusel. La investigación de campo y documental fueron a través de los datos recogidos a través de Internet; observación capítulos carrusel novela de transmisión en Brasil y en entrevistas y cuestionarios con la gente que veía la telenovela en cada uno de los tres países. Los estudios permitieron presentar algunas reflexiones relacionadas con la existencia de concepciones erróneas relativas a la buena imagen / buen maestro / a. La mayoría de las veces, las utopías se muestran como real y verdadero, apuntando a los beneficios de la venta de los productos anunciados por los patrocinadores de la transmisión de la industria cultural revitalizando así novela.
Preparação de membranas poliméricas porosas a partir de técnicas de espumação com agentes físicos de expansão
(Universidade Federal de São Carlos, 2016-07-07) Almeida, Ronaldo José de; Pessan, Luiz Antonio; https://lattes.cnpq.br/8276650236213537; https://lattes.cnpq.br/1198135738577362
The objective of this master’s thesis was to develop a process of manufacturing porous polymer membranes for microfiltration by a one-step foaming technique, using carbon dioxide (CO2) as physical blowing agent and ethanol (etOH) as co-solvent. Initially this work was conducted with PC/PMMA polymer blend samples in hollow fiber geometry, varying the blend composition, foaming temperature and the co-solvent content. It was determined that the blend composition PC/PMMA 60/40, sorbed with CO2 at 40°C with an ethanol content of 10%mol (CO2 molar basis) provided an opened porous morphology with potential for filtering applications. However, the pronounced fiber wall expansion ratio after the foaming process resulted in a considerable reduction of the fibers inner diameter, hindering its application as a hollow fiber membrane. Thus, it was necessary to change the hollow fiber geometry for flat films. DSC analysis showed that the PC/PMMA is a partially miscible blend. Gravimetric sorption tests revealed a higher sorption of diluents in polymers after adding ethanol as co-solvent with CO2, resulted from a stronger affinity between the polymers and the CO2/etOH mixture. Gas permeation tests showed a maximum pore size smaller than 10 micrometers, which is considered as an upper limit in the definition of microfiltration membranes. However, when compared to commercial membranes, the samples showed a considerably lower water permeation. With respect to the samples morphology, SEM images of the flat film samples revealed a cross section formed by a porous central region with micrometric interconnected pores, while the skin layers were composed of dense and foamed regions.
Determinação de arsênio total e inorgânico em sucos de frutas e arroz por ICP-MS
(Universidade Federal de São Carlos, 2016-07-07) Pinheiro, Fernanda Costa; Nóbrega, Joaquim de Araújo; https://lattes.cnpq.br/8833989058164529; https://lattes.cnpq.br/7672863657607448
Analytical procedures using inductively coupled plasma mass spectrometry (ICP-MS) for the determination of total As in rice samples and fruit juices and inorganic As in rice samples were developed. A microwave-assisted digestion procedure carried out in closed vessels was developed using hydrogen peroxide and dilute nitric acid for better control of the analytical blank. The selective extraction procedure used for the determination of inorganic As was characterized by its simplicity and use of non-toxic reagents. Inductively ICP-MS/MS in mass-shift mode was efficient for the determination of total As in juices samples by reaction of the analyte with oxygen, enabling the determination of arsenic without interferences by monitoring 75As16O+. The limit of detection was 0.013 μg L-1 and total As concentrations determined in juices ranged from 0.126 to 1.45 μg L-1. All samples had As concentrations significantly lower than the maximum tolerable limits imposed by legislation. Addition and recovery experiments performed in reactive gas operating mode led to quantitative recoveries showing the accuracy of the procedure. Determination of total and inorganic As in rice samples were performed using ICP-MS in acquisition mode with and without collision cell pressurized with He flow rate at 4.5 mL min-1. The limit of detection without collision gas acquisition mode was in the range of 0.005 a 0.007 mg kg-1. Recovery was 103 % for total As content certified for NIST 1568a rice flour. The total As concentrations in rice samples ranged from 0.073 to 0.665 mg kg-1 with a mean content of 0.278 mg kg-1. Three different types of rice grains had higher concentrations than the maximum tolerable level 0.30 mg kg-1 of total As imposed by ANVISA, FAO and WHO. The inorganic As determination procedure had detection limit ranged from 0.05 to 0.06 μg kg-1 and mean concentrations of 0.079 mg kg-1 for rice samples. All samples had inorganic As concentrations lower than the maximum tolerable limit 0.20 mg kg-1 imposed by FAO and WHO, except brown rice sample. The total and inorganic As concentrations higher than those allowed in legislations indicate the relevance of As monitoring in rice and the need to improve the Brazilian legislation which so far does not have a regulation for inorganic As.
Rivalidade entre os polos : a construção discursiva do Conselho Mundial da Água
(Universidade Federal de São Carlos, 2016-07-07) Espinoza, Rodrigo de Freitas; Martins, Rodrigo Constante; https://lattes.cnpq.br/6617183095074852; https://lattes.cnpq.br/2385823078490472
This work aims to characterize the discursive production of the World Water Council, an entity created in 1996 in order to set a plataform for the international debate on water. For this task, we will build, from the discourse plan and the socio-historical context, an analysis of the Environment Conferences and Water Conference as well as the documents and reports published by the Council devoted to the subject. Therefore, the methodological procedures adopted are documentary research, literature review and semi-structured interviews. In conceptual level, this research is supported by the post-colonial and decolonial framework. From this perspective, we have as main objective to analyze the possible impacts of colonialism in the discursive production on the environmental issue, especially in arguments built by the Council. We will be guided by the following hypothesis: the contours that characterize the boundaries of environmental issues are guided by a logic of coloniality of being, knowing and power, thus promoting a theme of entrapment in a discriminatory and hierarchical structure of the world.
