1. Uma análise do emprego no setor da construção civil nos estados do nordeste brasileiro: qualidade do emprego formal e o retorno da educação
The Construction Industry has gained prominence on the national scene due to its ability to generate employment, and absorb much of the disqualified labor. On that perspective, this research aims to measure the quality of formal employment and quantify the impact of schooling on income of Construction Industry workers in the states of Northeast Brazil. In or

2. Validação e estimativa da incerteza de método para análise de licopeno e β-caroteno em polpa de tomate por cromatografia líquida de alta eficiência
A method to quantify lycopene and β-carotene in freeze dried tomato pulp by high performance liquid chromatography (HLPC) was validated according to the criteria of selectivity, sensitivity, precision and accuracy, and uncertainty estimation of measurement was determined with data obtained in the validation. The validated method presented is selective in te

3. Probabilidade de progressão por série no Brasil: evolução, seletividade e aplicação de modelos de idade-período-coorte
The provision of the universal access to schooling and the assurance of students permanence in school has been the object of public policies in almost all nations. Education is conceived not only as a form of individuals emancipation, but also as an important factor to promote the economic and social development. Since the 90s, Brazil has seen the implementa

4. Modelo de custo para consultas por similaridade em espaços métricos / Cost model for similarity queries in metric spaces
Esta tese apresenta um modelo de custo para estimar o número de acessos a disco (custo de I/O) e o número de cálculos de distância (custo de CPU) para consultas por similaridade executadas sobre métodos de acesso métricos dinâmicos. O objetivo da criação do modelo é a otimização de consultas por similaridade em Sistemas de Gerenciamento de Bases

5. DESENVOLVIMENTO E VALIDAÇÃO DE MÉTODO FOSFORIMÉTRICO EM SUBSTRATO DE CELULOSE PARA DETERMINAÇÃO DE PIRENO E CRISENO / DEVELOPMENT AND VALIDATION OF THE PHOSPHORIMETRIC METHOD IN CELLULOSE SUBSTRATE TO DETERMINATION OF PYRENE AND CHRYSENE
In this work, solid surface room-temperature phosphorimetry (SSRTP) was used to develop ultra-trace and selective methods for determination of chrysene and pyrene in complex samples containing several other polycyclic aromatic hydrocarbons (PAHs). Both chrysene and pyrene were selected because they are classificated by the U.S. Environmental Protection Agenc

6. SELECTIVE DETERMINATION OF FLUORQUINOLONES FOR CELLULOSE SURFACE ROOMTEMPERATURE PHOSPHORIMETRY WHITH THORIUM NITRATE / DETERMINAÇÃO SELETIVA DE FLUOROQUINOLONAS POR FOSFORIMETRIA NA TEMPERATURA AMBIENTE SUPORTADA EM SUBSTRATO DE CELULOSE COM NITRATO DE TÓRIO
In this work, analytical methods based on solid surface room-temperature phosphorimetry were developed aiming the selective determination of fluorquinolones. More spectilly, thorium nitrate was evaluated as phosphorescence inducer aiming the sequential determination of norfloxacin (NOR) and levofloxacin (LEV), selective determination of NOR in presence of ci

7. Um algoritmo para estimação de estado em alimentadores de distribuição de energia elétrica com base no método da soma de potências
Most algorithms for state estimation based on the classical model are just adequate for use in transmission networks. Few algorithms were developed specifically for distribution systems, probably because of the little amount of data available in real time. Most overhead feeders possess just current and voltage measurements at the middle voltage bus-bar at th

8. The selectivity of the hair cell’s mechanoelectrical-transduction channel promotes Ca2+ flux at low Ca2+ concentrations
The mechanoelectrical-transduction channel of the hair cell is permeable to both monovalent and divalent cations. Because Ca2+ entering through the transduction channel serves as a feedback signal in the adaptation process that sets the channel’s open probability, an understanding of adaptation requires estimation of the magnitude of Ca2+ influx. To determ

9. Sparse but Selective and Potent Synaptic Transmission From the Globus Pallidus to the Subthalamic Nucleus
The reciprocally connected GABAergic globus pallidus (GP)-glutamatergic subthalamic nucleus (STN) network is critical for voluntary movement and an important site of dysfunction in movement disorders such as Parkinson's disease. Although the GP is a key determinant of STN activity, correlated GP-STN activity is rare under normal conditions. Here we define fu
