Pobreza e desigualdades socioterritorias: uma problematização acerca da perspectiva territorial nas politicas públicas sociais no município de Pau dos Ferros/RN

El presente trabajo se constituye en un estudio sobre la pobreza y las desigualdades socio territoriales en el Brasil, problematizando la perspectiva territorial de las políticas públicas sociales observando la distribución espacial del Índice de Desarrollo de las familias (IDF) en el municipio de Pau dos Ferros/RN, así como las principales políticas sociales, a ejemplo del Programa Bolsa Familia. En este sentido, el objetivo principal de esa disertación se dió en la tentativa de comprender la importancia de la lectura previa del territorio para la reflexión sobre la pobreza en su aspecto multidimensional y para la territorialización de las políticas Públicas sociales construidas en el intento de minimizar la problemática de la desigualdad social, observando la distribución espacial do IDF en el municipio de Pau dos Ferros/RN. A partir del objetivo general trazado, hicimos una revisión teórica sobre los temas, pobreza, desigualdades sociales y políticas públicas, en el primero caso atentando para el aspecto multidimensional de esta, abogando la importancia de analizarnos la pobreza no apenas por el nivel de rienda, pero considerando otras dimensiones que corroboran para la constitución del ser pobre, como habitaciones precarias, falta de saneamiento básico e infraestructura, el no acceso a la salud, la educación y los otros servicios que posibilitan el individuo vivir con el mejor dignidad. Comprendiendo la importancia del conocimiento previo del territorio para que ocurra las debidas reflexiones e intervenciones en la realidad territorial buscamos reflexionar acerca de ese concepto en sus nexos con la construcción e implementación de las políticas públicas sociales teniendo la Política Nacional de Asistencia Social (PNAS) como política esencial y también el el Programa Bolsa Familia (PBF), una vez que buscamos compreender su importancia a partir de la visión del sujeto, o sea las beneficiadas del PBF en el Municipio de Pau dos Ferros. Para tanto, hicimos entrevistas orales con las beneficiadas del PBF que fueron elegidas aislada a partir de los equipos del CRAS, además de la aplicación de cuestionarios semiesctructurados y abiertos con gestores y asistentes sociales del muninicipio.Buscamos además trabajar con algunos datos del CadÚnico para el município en estudio proponiendo analisar las condiciones sociales y económicas de las famílias cadastradas. Algunos resultados fueron posibles, a saber, es necesario interpretarse la pobreza a partir de varias dimensiones para no tener el riesgo de quedarnos solamente en la perspectiva financiera, o sea de la rienda, que mismo sirva para lo emergencial no es suficiente para transformar las condiciones de vida de las famílias; PNAS puede ser considerada como un avanzo de la política social en el Brasil una vez que posuye importancia fundamental en la familia. Sin embargo, es preciso avanzar en la interpretación del territorio que en la política y en el habla de los agentes sociales , es interpretación apenas como un recorte donde deberán ocurrir las acciones para minimizar la pobreza ; al fin, o PBF es un programa de urgencia moral una vez que combate lo mas emergencial que es el directo de sobrevivir , pero aun no conseguió transformar de una manera significativa la pobreza en el país

Os 'troncos velhos' e os 'quilombinhos': memória genealógica, território e afirmação étnica em Boa Vista dos Negros (RN)

Durante a pesquisa visando à elaboração do relatório antropológico de Boa Vista dos Negros, comunidade quilombola do Seridó (RN), verificamos que o grupo conserva uma longa memória genealógica e que, apesar das mudanças ocorridas na organização econômica e social do grupo, as principais formas de solidariedade foram mantidas. Queremos, aqui, refletir sobre a importância da noção de família, a transmissão dos nomes e da memória genealógica na definição do território quilombola. Na ocasião, serão analisados como os elementos da cultura tradicional são ressignificados ao longo do processo de afirmação étnica

A combined method for evaluating radon and progeny in waters and its use at Guarani aquifer, São Paulo State, Brazil

A combined method for evaluating radon (Rn-222) and progeny (Pb-214 and Bi-214) in water was developed by using inexpensive alpha scintillation Counting and gamma ray spectrometry through NaI(Tl) scintillation detectors. A groundwater sample collected at the Pocos de Caldas alkaline massif in Brazil was submitted to the technique in order to assure its applicability by comparing the volumetric activities by different methods. Similar volumetric activity was determined for Pb-214 and Bi-214 in the sample analyzed that is compatible with the expected condition of radioactive equilibrium between these nuclides. The combined method was successfully used to analyze groundwater samples from Guarani aquifer in S (a) over tildeo Paulo State, Brazil, and the results of the measurements indicated that Pb-214 and Bi-214 provide useful information concerning the evaluation of the drinking water quality in terms of radiological aspects. This is because they are directly identified in the water samples, without the need of requiring the assumption of the establishment of the transient equilibrium condition with its parent Rn-222.

Doses from Rn-222, Ra-226, and Ra-228 in groundwater from Guarani aquifer, South America

Groundwater samples were analysed for Rn-222, Ra-226, and Ra-228 in Guarani aquifer spreading around I million kin 2 within four countries in South America, and it was found that their activity concentrations are lognormally distributed. Population-weighted average activity concentration for these radionuclides allowed to estimate a value: either slightly higher (0.13 mSv/year) than 0.1 mSv for the total effective dose or two times higher (0.21 mSv/year) than this limit, depending on the choice of the dose conversion factor. Such calculation adds useful information for the appropriate management of this transboundary aquifer that is socially and economically very important to about 15 million inhabitants living in Brazil, Argentina, Uruguay and Paraguay.

Health risk related to radon in a thermal spa utilizing waters from Guarani aquifer

This investigation was carried out within the Parana sedimentary basin, Brazil, involved the sampling of groundwater and air, and was realized with the purpose of evaluating the radioactivity, due to radon gas, in a thermal spa utilizing the waters from Guarani (Botucatu-Piramboia) aquifer. The results reported here provide additional information relative to that of previous studies focusing on the presence of radionuclides in the aquifer, which have mainly characterized those belonging to uranium and thorium series decay, such as the uranium isotopes (U-238 and U-234), radium isotopes (Ra-226 and Ra-228), radon daughters (Bi-214 and Pb-214) and radon (Rn-222) itself the results obtained were compared with the maximum permissible concentration limits in air and drinking water defined by international standards, such as the guidelines for drinking water quality established by the World Health Organization. The possible processes responsible for the presence of radon in the aquifer were also considered in order to evaluate the data obtained.

The implications of laboratory Rn-222 flux measurements to the radioactivity in groundwaters: the case of a karstic limestone aquifer

Laboratory time-scale experiments were conducted on Carboniferous Limestone gravels from the Mendip Hills area, England, with the purpose of evaluating the release of Rn-222 to the water phase. The specific surface areas of the samples were 4.14 and 1.69 cm g(-1), which provided, respectively, values of 50.6 and 12.7 pCi for the released Rn. These results allowed the calculation of the emanation coefficient of this rock matrix with respect to the release of Rn, where completely different values corresponding to 23% and 6% were found, suggesting that the extent to which grain boundaries or imperfections in aggregates of micro-crystals of calcite intersect the particle surface certainly affects the Rn release. They also permitted the evaluation of models for the generation of Rn in rocks and transfer to water, in order to interpret the radioactivity due to this gas in groundwaters from the karstic aquifer of the Mendip Hills area, where the calculated activities in groundwater based on the values of 23% and 6% for the emanation coefficient were about 51 and 15 times higher than actually measured in groundwater. Therefore, the emanation coefficient in nature is considerably smaller than in the lab experiment, and another factor k (0 < k < 1) may be introduced into the equations related to the modelling, with the aim of adjusting the theoretical-practical results.
