1. Estudo do efeito da adição da escória de aciaria no processamento e propriedades finais de telhas cerâmicas
Neste trabalho é estudado o efeito da adição da escória de aciaria em massas cerâmicas para indústrias de cerâmica vermelha, visando contribuir com o aproveitamento desses rejeitos. Foi feito uma avaliação da sua adição à massa cerâmica para produção de telhas. O panorama da indústria cerâmica no estado do Piauí é bastante promissor. Difer

2. Estruturas de aço sem revestimento contra fogo externas a edifícios em incêndio. / External unprotected steel structures in fire situation.
Steelworks outside a building in fire situation are exposed to radiation that come from the windows in the façade and from flames, as well as the convection of hot gases. The absorption of the heat for the element depends on its placement in relation to the openings. Margaret Law, based on many experimental data about fire in buildings, estimated the extern

5. AN INTEGRATING MODEL FOR THE ACQUISITION AND USE OF METALLURGICAL COALS IN STEELWORKS
The coal supply to steelworks is usually seen as presenting two distinct but related problems: (i) how to determine the amounts of different types of coals to buy from the available suppliers, typically planned ahead for a year and (ii) the operational problem of using the coals available in the stockyards on a daily and weekly basis. The supply model develo

6. Caracterização de toxicidade de efluentes de usina siderúrgica mediante bioensaios com microorganismos / Characterization of steel mill´s effluents toxicity using bioassays Microtox and Ames
Cubatão, na Baixada Santista ficou caracterizada na década de 70 pelo caos ambiental propiciado pela instalação de dezenas de indústrias de base, sem planejamento territorial urbano adequado, sem estudo de impacto ambiental e com poucos equipamentos de controle de poluição do ar, solo e água. Dentre as indústrias sediadas no pólo industrial de Cuba

10. A mortality study of coke oven workers in two South Wales integrated steelworks.
Six hundred and ten coke oven personnel were studied retrospectively over a period of 11 years (1954-65). During this time 82 died, 88 retired and 80 left, but all were treated. The Standardised Mortality Ratios (SMRs) have been calculated for four principal causes which have then been further analysed into 30 subgroups. The work was limited because the popu

11. A nested case-control study of fatal work related injuries among Brazilian steel workers.
OBJECTIVES: To estimate the relative risk of death from work related injury in a steelworks, associated with exposure to various occupational hazards, sociodemographic factors, and medical history. MATERIAL AND METHODS: The study was a nested case-control design. It was based on a cohort of men employed in the steel plant of USIMINAS, Brazil between January

12. Leukaemia clusters in childhood: geographical analysis in Britain.
STUDY OBJECTIVE--To validate previously demonstrated spatial clustering of childhood leukaemias by showing relative proximities of selected map features to cluster locations, compared with control locations. If clusters are real, then they are likely to be close to a determining hazard. DESIGN--Cluster postcode loci and partially matched control postcodes we
