This work intends to develop an approach based through scientific criteria in the operational diagnosis of ponds of stabilization, starting from analyses accomplished in loco and in laboratory of 78 systems of sewer treatment through ponds of stabilization in the State of Rio Grande do Norte. The objectives of the research are: to map, to evaluate and to diagnose the operational acting of the ponds of stabilization of the state of Rio Grande do Norte, through visits in loco and analyses laboratory; to build a SIG, through the map rain, locate the points of releases of sewages of the systems of existent ponds in Rio Grande do Norte, as well as operational data and his/her respective efficiency diagnosis in the removal of BOD and Coliforms Termotolerantes; to evaluate, in real scale, three systems of ponds of stabilization of RN in the operational efficiency for the parameters BOD5, COD, pH, Temperature, OD and Coliforms Termotolerantes. Of 78 ETEs of appraised RN just, 9% or 7 had maximum concepts in what concerns the removal of BOD and Coliforms Termotolerantes and 41% or 32, they had the worst concepts in term of operational efficiency. The flowing concentrations ETEs of RN of BOD and Coliforms were of 410mg/L and 2,50x107UFC/100ml, the predominant configuration is of the type F1+M1+M2, the relationship BOD/COD revealed for the sewer tributary characteristic biodegradable high. For the study of case of 3 ETEs, the best operational efficiencies in decreasing order were: Cidade (Municipal district), it Roça (State) and São Miguel (SAAE). The removals of final BOD were 51,6mg/L; 108,27mg/L and 62,6mg/L, tends efficiency of 82%; 74% and 81%. In term of coliforms removal in the final effluentes were 1,90x103UFC/100ml; 1,50x104UFC/100ml and 3,10x104UFC/100ml, tends efficiencies of 99,99%; 99,95% and 99,90%. In what it concerns the practice of agricultural reúso of cultures consumed raw, none of 3 ETEs assisted the parameters of the Resolution CONAMA 357/05, for other reúso practices, all assisted the categories B and C of OMS. For release in body receiving ETE Cidade just, they assist the demands of the resolution of CONAMA 357/05, by study of purification solemnity of the receiving body. The maintenance lack and operation; exclusive operator in ETEs and operation knowledge was the contributory factors for the operational fall in appraised ETEs of RN

Ocupando uma área de 665,7km2 (equivalente a 1,25% da superfície estadual), o Município de Lajes até o início do século XX era um pequeno distrito do Município de Jardim de Angicos, localizada na Região Central do Estado do Rio Grande do Norte. Quando decretado município, em 1914, Lajes tornou-se o principal entreposto comercial do estado, uma vez que sua posição geográfica a colocava como rota principal entre os municípios produtores de mercadorias e a capital do estado, Natal, situada a 125km a Leste do município. Esta confortável posição de entreposto comercial cristalizou-se com a construção da estrada de ferro Sampaio Correia, em 1919, que agilizou o escoamento das mercadorias advindas do interior com Natal, principalmente o algodão, que até a década de 1980 era a principal fonte econômica do Estado do Rio Grande do Norte. Com a crise do algodão e a construção de estradas ligando diretamente os mercados produtores com a capital, Lajes perde a condição de principal entreposto comercial do estado, e sua economia entra em decadência. Vastas áreas de caatinga onde outrora se plantava algodão foram abandonadas, deixando os solos destas terras livres para a ação erosiva dos ventos e das torrenciais chuvas de outono. Situada numa porção do estado que sofre direto sombreamento das escarpas da Serra do Feiticeiro, o município de Lajes tem se configurado como um importante laboratório para o estudo da desertificação no Estado do Rio Grande do Norte. A partir de uma análise Geossistêmica, procurou-se diagnosticar o atual quadro da desertificação nesta porção semi-árida do estado. Para tanto, utilizou-se os métodos quantitativos de análise, dentre eles os métodos desenvolvidos durante a elaboração do Pan Brasil, com a construção dos Balanços Hídricos e Índices de Aridez do município. Os dados referentes aos índices de aridez de Lajes apontam para um profundo processo de ressecamento do ar na região, corroborando inclusive com os dados referentes ao aquecimento global divulgados pelo IPCC (Intergovernamental Panel on Climate Change) no mês de fevereiro de 2007

Lung cancer is one of the most common types of cancer and has the highest mortality rate. Patient survival is highly correlated with early detection. Computed Tomography technology services the early detection of lung cancer tremendously by offering aminimally invasive medical diagnostic tool. However, the large amount of data per examination makes the interpretation difficult. This leads to omission of nodules by human radiologist. This thesis presents a development of a computer-aided diagnosis system (CADe) tool for the detection of lung nodules in Computed Tomography study. The system, called LCD-OpenPACS (Lung Cancer Detection - OpenPACS) should be integrated into the OpenPACS system and have all the requirements for use in the workflow of health facilities belonging to the SUS (Brazilian health system). The LCD-OpenPACS made use of image processing techniques (Region Growing and Watershed), feature extraction (Histogram of Gradient Oriented), dimensionality reduction (Principal Component Analysis) and classifier (Support Vector Machine). System was tested on 220 cases, totaling 296 pulmonary nodules, with sensitivity of 94.4% and 7.04 false positives per case. The total time for processing was approximately 10 minutes per case. The system has detected pulmonary nodules (solitary, juxtavascular, ground-glass opacity and juxtapleural) between 3 mm and 30 mm.
