2. HOT AEROSOL FIRE EXTINGUISHING AGENTS AND THE ASSOCIATED TECHNOLOGIES: A REVIEW
Abstract Since the phase out of Halon extinguishers in the 1980s, hot aerosol fire suppression technology has gained much attention. Unlike traditional inert gas, foam, water mist and Halon fire suppression agents, hot aerosol fire extinguishing agents do not need to be driven out by pressurized gases and can extinguish class A, B, C, D and K fires at 30 to

3. Modelos numéricos de vigas mistas de aço e concreto pertencentes a sistemas de pisos mistos de pequena altura em situação de incêndio / Numerical modelling of composite slim floor beams in fire
Slim floor frames consists on structural system in which the steel beam is completely or partially inserted in a concrete slab, that is usually used in profiled steel decks systems. The main goal of the slim floor systems is to obtain a minimum height of the composite beam section and, consequently, achieve a higher height of the floor or a lower total heigh

11. Ergonomia na aviaÃÃo: um estudo crÃtico da responsabilidade dos pilotos na causalidade dos acidentes
Oficial documents about aviation accidents always attribute the responsability to pilots or on a combined cause participation with others causes as environment or methereological factor at a proportion near 80%. We must consider that the pilot receives the machine that begins its design years before. Now he has the obligation to mantain this artefact flying,
