1. UNA CONCEPCIÓN INTEGRADORA DE LA MOTIVACIÓN HUMANA
RESUMO As teorias da motivação desenvolvidas no século XX são opostas. Requer-se uma que, sobre a base dos fatos, integre harmonicamente os resultados alcançados. Destacamos a aprendizagem das necessidades, baseado em determinantes orgânicos e adquiridos, mediante o reforço afetivo dos objetos do mundo exterior e das palavras em que se canalizam. Os r

2. Accuracy and simultaneous selection gains for N-stress tolerance and N-use efficiency in maize tropical lines
ABSTRACT Maize plants can be N-use efficient or N-stress tolerant. The first have high yields in favorable environments but is drastically affected under stress conditions; whereas the second show satisfactory yields in stressful environments but only moderate ones under optimal conditions. In this context, our aim was to assess the possibility of selecting

3. Aplicação do modelo QUAL2Kw para avaliação da capacidade de assimilação de cargas pontuais no Rio Itapanhaú. / Application of the model QUAL2Kw for assessment of point sources at Itapanhaú River.
The presence of point sources in rivers and streams implicates in downstream impacts that can commit their respective future uses. For this reason, the mathematical modeling comes as a fundamental tool in the evaluation of those discharges in sense to evaluate legal service and to subsidize the licensing of activities to the competent organs. The main object

4. Intonational strategies in ensemble singing
The aim of the research was to find out about intonational strategies in the performance situation. The singing voice was chosen as the appropriate subject for experimental work, due to its superior capability to define pitch as compared to other musical instruments. Ensemble singing was also required, as harmonic context may be important in the clarificatio

5. MÉTODOS APROXIMADOS DE SOLUÇÃO DE SISTEMAS DINÂMICOS NÃO-LINEARES / APPROXIMATE SOLUTION METHODS FOR NONLINEAR DYNAMICAL SYSTEMS
Nonlinear dynamical systems are rather common in engineering. This class of problems is usually solved by numerical integration or through the use of ap- proximate analytical methods (perturbation methods) or semi-analytical meth- ods such as the harmonic balance method. The numerical integration is a slow and cumbersome process in parametric analyses. The o

6. Aplicabilidade do princípio constitucional da proteção do consumidor aos contratos eletrônicos. / Applicability of the constitutional principle of consumer protection over the electronic contracts.
The applicability of the constitutional principle of consumer protection is indicated here as the main solution to fill the legal gap concerning the new electronic contracts. From an unknown and irrelevant precept in the consumption relationships developed during the Liberal State, to a leading factor for the economical activity of the Social and Constitutio

7. Determinação do conteúdo harmônico de corrente baseada em redes neurais artificiais para cargas não-lineares monofásicas / Determination of the current harmonic content based on artificial neural networks for single-phase non-linear loads
In this thesis artificial neural networks are employed in a novel approach to identifying harmonic components of the single-phase nonlinear load current, whose amplitudes and phase angles are subject to unpredictable changes in steady-state. An identified harmonics number is previously selected. These harmonics are present in the non-linear loads current of

8. CaracterizaÃÃo Ãptica de materiais nanoestruturados por tÃcnicas de geraÃÃo de segundo e terceiro harmÃnico
This work is dedicated to the optical characterization of nanostructured materials that are of interest for non-linear optics, optoelectronics and nanophotonics. The hyper- Rayleigh scattering (HRS) technique and the third harmonic generation (THG) technique were used. The materials investigated were a glass-ceramics containing sodium niobate (NaNbO3) nanocr

9. Access the medicines and pharmaceutical patents: systematic analysis of protection under the perspective of the sustainable development / Acesso a medicamentos e patentes farmacêuticas : análise sistêmica sob a perspectiva do desenvolvimento sustentável
The protection for the right to the access for the medicines and the right from pharmaceutical patents is carried through by the international order and the national jurisprudence. One and another one are complementary and harmonic, here it is that they possess for bedding the human rights, which are recognized, in Brazil, as of basic nature to the right for

10. ANÁLISE COMPARATIVA DE INVERSORES MULTINÍVEIS COM CÉLULAS H-BRIDGE CONECTADAS EM SÉRIE / COMPARISON ANALYSIS OF CASCADED MULTILEVEL INVERTERS
This Master Thesis presents a methodology to compare different topologies and configurations of multilevel systems applied to drive medium voltage induction motors. Initially, it presents the input and output parameters that must be supplied by the power drivesystems manufacturer. Then, the mathematical models of the performance indexes used are presented, b

11. Câmbio e integração regional: flutuação conjunta e otimização dinâmica para o mercosul
The commercial and economic integration between Brazil and Argentina has been frequently put under risk and uncertainty, so in MERCOSUR, essentially manifested in the tariff compensation. Accounting this concern, one can investigate the importance of exchange in the integration process, the possibility of establishing an harmonic exchange management and its

12. Orbital evolution and maneuvers around non-spherical bodies / Evolução orbital e manobras em torno de corpos não-esféricos
In the last years several asteroids had their shapes identified using images from space probes or through the indirect radar data determination. In a general way, these asteroids have forms quite different from spherical. Conventional spherical harmonic representations of the gravitational potential of such bodies require expansions of high degree and order,
