Em relação à prevenção e combate a incêndios, é correto afirmar que
Considerada como “ciência básica” da saúde coletiva, a Epidemiologia pode ser definida como a ciência que estuda os padrões da ocorrência de doenças em populações humanas e os fatores determinantes desses padrões, sendo de importante aplicação no estudo da saúde dos trabalhadores. Dessa maneira,
O corpo humano representa um sistema aberto, trocando matéria e energia com o ambiente por meio de numerosas e complexas reações. Quando essa interação envolve substâncias tóxicas no ambiente de trabalho, configura-se a área de conhecimento da Toxicologia Industrial, em que
A ventilação industrial constitui, em relação ao ambiente, importante medida de prevenção e controle na Higiene do Trabalho. Assim,
Para a prevenção de distúrbios de saúde de caráter psicológico ou físico nos trabalhadores, as modalidades pelas quais são repartidas as funções entre os operadores e as máquinas, e caracterizam a divisão do trabalho, devem considerar que
Na Fisiologia, o estudo das funções orgânicas, processos ou atividades vitais deve considerar o impacto causado por fatores ambientais, pois a interação entre o organismo e o ambiente externo exige adaptação constante e sistêmica em processos como
Os dados estatísticos de Acidentes de Trabalho divulgados nos últimos anos pelo Ministério da Previdência Social indicam que
A respeito da psicologia aplicada à prevenção de acidentes e doenças relacionadas ao trabalho, é correto afirmar que
De acordo com a Norma Regulamentadora 12 – Segurança no Trabalho em Máquinas e Equipamentos,
A Lei n.º 6.514, de 22 de dezembro de 1977, alterou o Capítulo V, do Título II da Consolidação das Leis do Trabalho, relativa à segurança e medicina do trabalho. De acordo com ela,
Assinale a alternativa que indica o agente extintor de fogo considerado por ter a menor toxidade.
Para os sistemas de proteção contraincêndio e respectivos circuitos elétricos, instalados em aeronaves,
Amortecedores hidráulicos, usados em trens de pouso,
A válvula redutora de pressão hidráulica, presente na aeronave,
A tensão nos cabos usados para o comando da aeronave é controlada por
O coeficiente de expansão térmica da maioria dos materiais plásticos, usados em acabamentos internos de aeronaves, é
Como regra geral, em uma junta de chapas metálicas, o diâmetro do rebite deveria ser igual
Supercomputers
One definition for a supercomputer is “the most powerful computer available at any given time.” These machines are used to solve complex problems such as the design of a supersonic aircraft, modeling of global climates, the structure of oil-bearing formations within the Earth, the molecular design of new drugs, or the prediction of complex financial behavior in securities markets. Two of the first supercomputers were the Control Data Corporation CDC 6600 and CDC 7600. Both were developed by Seymour Cray, one of the founders of CDC. In 1972, Cray left to found Cray Research, Inc., and in 1976 developed the Cray-1, generally acknowledged to be the first true supercomputer.
The Cray-1 used high-speed emitter coupled logic (ECL), the fastest (and most power hungry) logic circuits available at the time. The computer was packaged as a 6.5 ft. high cylinder surrounded by a circular seat. Each circuit board was mounted on a copper heat exchanger through which liquid freon was circulated. The total power consumption of the computer was 128 KW! Processing speed was 130 MFLOPS (millions of floating-point operations per second). In all, 63 Cray-1 computers were sold (at a cost of $5.1 million each).
