13. ELECTRIC DISTRIBUTION POWER SYSTEMS RELIABILITY OPTIMIZATION: An Approach Considering the Selection and Allocation of Protection and Switching Devices / OTIMIZAÇÃO DA CONFIABILIDADE DE SISTEMAS DE DISTRIBUIÇÃO DE ENERGIA ELÉTRICA: Uma Abordagem Considerando a Seleção e Alocação de Dispositivos de Proteção e Manobras
One of the main goals of the electric utilities is to provide energy to its customers in a reliable and low cost way. Traditionally, the electricity sector regulatory commissions impose continuity targets, which must be carried out, to avoid great penalties. For many years, the electric utilities have adopted the practice of allowing the increment of tempora

14. As capturas nas agÃncias reguladoras e o debatesobre a legitimaÃÃo do Estado Regulador:a produÃÃo democrÃtica do direito e os desafios do direitoadministrativo contemporÃneo / The capture in the regulatory agencies and the debate over the legitimation of Regulatory State: the democratic production of law and the challenges of contemporary administrative law
This dissertation introduces a study on the regulatory state considering the issues of autonomous regulatory entities and analyzing the possibility of constructing democratic legitimacy. We try to comprehend whether the capture of regulatory agencies would be a mere model failure, which could be rectified by specific instruments, or whether it would indicate

15. Estudo de fatores humanos, e observação dos seus aspectos básicos, focados em operadores do reator de pesquisa IEA-R1, objetivando a prevenção de acidentes ocasionados por falhas humanas / STUDY OF HUMAN FACTORS, AND ITS BASIC ASPECTS, FOCUSING THE IEA-R1 RESEARCH REACTOR OPERATORS, AIMING AT THE PREVENTION OF ACCIDENTS CAUSED BY HUMAN FAILURES
This work presents a study of human factors and possible human failure reasons that can cause incidents, accidents and workers exposition, associated to risks intrinsic to the profession. The objective is to contribute with the operators of IEA-R1 reactor located at IPEN CNEN/SP. Accidents in the technological field, including the nuclear, have shown that th

16. Metodologia FMEA-FUZZY aplicada à gestão de indicadores de continuidade individuais de sistemas de distribuição de energia elétrica
The electrical energy service has become essential for our society. This service is used to develop our economy and to improve quality of life. As consequence, our society has been demanding higher levels of quality of service. In Brazil, the regulatory agency ANEEL (National Government Agency for Electricity) is the entity responsible to define the targets

17. InteraÃÃo transitÃria entre transformadores de potencial capacitivos e linhas de transmissÃo: uma contribuiÃÃo para minimizar falhas
Coupling capacitor voltage transformers (CCVT) are widely used in power systems for monitoring, protection relays and control aplications. Failure of this equipment may cause unexpected outages of transmission lines (TL), which may result in severe penalties as imposed by the regulatory agency of the government. This fact requires speeding maintenance proced

18. Sistemas neuromodulatórios: implicações fisiopatológicas / Neuromodulatory systems: patophysiologic implications
Adenosine has been shown to modulate cardiovascular control at the levels of the nucleus tractus solitarii (NTS). This study shows the distribution and density of adenosine A1 receptor within the nucleus tractus solitarii (NTS) of Wistar Kyoto (WKY) and spontaneously hypertensive (SHR) rats from birth to adulthood (1,15,30 and 90 day-old). [3H]DPCPX was used

19. Regulação sanitária de produtos para a saúde no Brasil e no Reino Unido: o caso dos equipamentos eletromédicos. / Medical devices regulation in Brazil and in the United Kingdom: the electromedical equipment case.
Este estudo analisa a regulação sanitária de equipamentos eletromédicos no Brasil e no Reino Unido. Busca identificar e analisar as semelhanças e diferenças entre os dois regimes e discutir em que medida eles protegem a saúde da população dos riscos decorrentes desses equipamentos. Optou-se por realizar pesquisa qualitativa exploratória com coleta

20. Analysis of genomic sequence features related to alternative splicing events (intron retention) in the human transcriptome / Análise de características das seqüencias genômicas relacionadas a eventos de splicing alternativo do tipo retenção de intron no transcriptoma humano
Most eukaryotic genes are split in exons and introns, requiring mRNA processing to remove intervening sequences and join exons (splicing). Exon/intron borders are defined by splice sites that are normally recognized with high fidelity, yielding the same processed mRNA each time. Notwithstanding such precise recognition, alternative joining of exons has been

21. Expressão de fatores de regulação miogenica e metaloproteinases no musculo estriado esqueletico de ratos com insuficiencia cardiaca / Myogenic regulatory factors and metalloproteinase expression in rat skeletal muscle with heart failure
Background: Heart failure (HF) is associated with a skeletal muscle myopathy with increased expression of fast myosin heavy chains (MHC) and extracellular matrix (ECM) alterations. The skeletal muscle-specific molecular regulatory mechanisms controlling MHC expression during HF have not been described. Myogenic regulatory factors (MRF), a family of transcrip

22. Myogenic regulatory factors expression in rat diaphragm muscle with heart failure / Expressão dos fatores de regulação miogenica no musculo diafragma de ratos com insuficiencia cardiaca
A insuficiência cardíaca (IC) é caracterizada pela intolerância ao exercício físico, devido à fadiga precoce e à dispnéia. Entre as alterações que podem contribuir para a dispnéia nesta síndrome, tem sido descrita a miopatia diafragmática com atrofia e mudanças na miosina de cadeia pesada (MHC) do tipo II "rápida" para a do tipo I "lenta". En

23. Monitoramento e diagnÃstico de estado de disjuntores de alta e extra alta tensÃo como tÃcnica de manutenÃÃo preditiva
Concerning to the present rules applied to the energy sector in Brazil, quality of services plays an important part in determining conditions in which better results will be achieved. The Brazilian Electricity Regulatory Agency ANEEL - has imposed severe penalties to the electric companies involving large amount of money in case of equipment failures.

24. Efeitos do losartan e espironolactona sobre a estrutura e função do coração de ratos espontaneamente hipertensos
Background: The clinical syndrome of heart failure is the final pathway for myriad diseases that affect the heart, mainly ischemic heart disease and hypertension. Left ventricular hypertrophy is accompanied by a structural remodeling that includes myocyte hypertrophy and interstitial fibrosis. These structural abnormalities related to fibrosis lead to increa
