thus ensuring that the undue exhaust steam or firing of a safety valve, can injure someone. Also ensures that during the drafting of the logic of CLP sought to guarantee of inter-locking electric and it is hoped that this is the fastest and with simple action to be modified in case of need, for the electro-mechanical.

utilizando-se a liga a base de cobalto comercialmente conhecida como Stellite 6, como material de adição na forma de pó e arame. A pesquisa foi realizada com a expectativa de ser aplicada nas operações de revestimentos de superfícies, em especial em pás de turbinas hidráulicas desgastadas por cavitação. A seleção do material de adição a ser empregado depende da natureza do mecanismo de desgaste encontrado. No Labsolda, a liga Stellite 6 vem sendo uma das mais utilizadas, por apresentar…

quanto da mora 11 l”. Assim, os moralistas querem fazer pensar que a ciência está livre da moral, quando na verdade a moral está “embutida” na ciência, e a maioria dos indivíduos nem se apercebe disso acreditando nessa faláci a. A história tem um pa pel central no pensamento nietzschiano, pois é com ela qu e ele procura demonstrar a co rreção de suas assertivas. Ele afirma nada poder ser subtraído à passage m do tempo e ao curso da história, pois a história irá demonstrar que,…

theoretical basis, regarding regulated sources, generating graphics of voltage, schematic figures of the circuit, apart from providing the necessary support for the electrical engineering student to make his own source in practice. Despite being a simple computational tool, it presents an embracing feature when it comes to projects of power supply, and can meet any user, beginner or advanced, who needs to supply any electronic circuit. Key-words: Power Supplies, FOSS, Computing…

Arquitetura e Urbanismo, Universidade de São Paulo, 2013. 207 f. : il. The life and work of Vital Maria Tavares Pessôa de Melo (1936-2010) are the purpose of this essay. Pupil of the first generation of Pernambuco’s modern Architects, Vital produced a simple, but sophisticated architecture, which critically absorbed modern premises and blended them to local cultural and climatic inputs. His technical understanding of construction, his multiprogram expertise, his knowledge of historic…

problem has two aspects. The first refers to the basic criterion to be adopted in the guidance of investment. Such criterion, NURKSE tells us, is that of social marginal productivity. The adoption of this criterion leads to the conclusion that the simple mechanism of market prices does not guarantee the best utilization of resources. The other problem raised by Prof. NURKSE in this connection is that of the repercussion of foreign investment on the balance of payments. This problem…

velocidade e pressão, como é o modelo k- utilizado na análise desenvolvida. São analisadas várias turbinas (i.e., deslocamento positivo (PD), bomba a funcionar como turbina (PAT), hélice com evoluta a montante, hélice tubular quatro e com cinco pás) e desenvolvidas análises de sensibilidade às melhores configurações, assim como efectuadas comparações entre curvas de desempenho. Para a generalidade das turbinas seleccionadas desenvolvem-se análises comparativas entre as…
