Shelf-Ocean material exchange influencing the Atlantic chemical composition off...
Silva, T.; Martins, V.; Santos, J. F.; Dias, J. A.; Ferreira da Silva, E.; Rocha, F.; Ribeiro, S.Rivers are the main conduit of sediment to the shelf. The basin geology, the drainage area and the discharge rate are the major factors that determine their sediment load (Milliman and Syvistski, 1992). Besides suspended particles, dissolved components may also give some information on the eroded crust. Sr isotopes in carbonate shells of biological organisms have been used to study, in the geological record, th...
Situação epidemiológica da brucelose bovina no Estado do Paraná
Dias,J.A.; Müller,E.E.; Dias,R.A.; Freitas,J.C.; Amaku,M.; Ferreira,F.; Silva,M.C.P.; Lôbo,J.R.; Figueiredo,V.C.F.; Gonçalves,V.S.P.; Ferreira Neto,J.S.Realizou-se um estudo para caracterizar a situação epidemiológica da brucelose bovina no Estado do Paraná. O Estado foi estratificado em sete circuitos produtores ou regiões. Em cada circuito foram amostradas aleatoriamente cerca de 300 propriedades e, dentro dessas, foi escolhido de forma aleatória um número pré-estabelecido de animais, dos quais foi obtida uma amostra de sangue.

Penetrability of chloride ions in concrete protected by an acrylic painting
Aguiar, J. L. Barroso de; Dias, J. A.In order do decrease the penetrability of chloride ions in concrete the use of paintings based on polymers can be a good solution. The use of acrylic paintings is recommended because they have good resistance to ultraviolet radiation. It is important to quantify the decrease of chloride ions penetrability obtained by the use of this kind of paintings. The durability of the polymeric paintings is another aspect ...

The Calmette-Guérin bacillus (BCG). An agent to consider in pediatric infection.
Marcelino, F; Departamento de Pediatria, Hospital de S. João, Porto.; Vasconcellos, G; Almeida, A; Pereira, F; Rodrigues, F; Dias, J AComplications occurring a long time after BCG vaccination in healthy children have been occasionally referred, despite being rare. Osteitis seems to be the most frequent of those complications; therefore it must be considered in the differential diagnosis of that sort of lesions. The authors report a case of a 15 month old boy, previously healthy, who suffered an enlargement of the right foot for 3 weeks, unres...
A methodology for the diagnosis and follow-up of the evolution of acute hepatit...
Dias, J A; Serviço de Pediatria, Hospital de S. João, Porto.; Medina, M; Antonio, A M; Brandão, N; Cabral, J; Carvalho, H; Gomes, J L; Gonçalves, IThe Working Group of the Section of Paediatric Gastroenterology and Nutrition of the Portuguese Society of Paediatrics established a protocol for the investigation of children with acute hepatitis. The main purpose of this proposal is to allow appropriate etiologic investigations and avoid unnecessary tests that are expensive and do not add relevant information for the correct follow-up of these patients. ; Th...
The epidemiology of pancreatic disease in Portugal.
Dias, J A; Divisão de Epidemiologia e Bioestatistica, Direcção-Geral de Saúde, Lisboa.; Giria, J AThe authors describe the most relevant aspects of the occurrence, distribution and relative importance of the main diseases of the Pancreas in Portugal, comparing their incidence and mortality rates with other European countries in recent years. The main risk factors associated with pancreatic cancer are referred, stressing the appropriate preventive measures. Hospital management and cost-efficiency analysis of...
The evolution of mortality from ischemic heart disease and cerebrovascular dise...
de Sá, P; Instituto de Medicina Preventiva, Faculdade de Medicina de Lisboa.; Dias, J A; Miguel, J MBy late 70's, Portugal had one of the lowest IHD mortality rates amongst developed countries, with a declining trend. As for CVD, Portugal's figures were one of the highest, and showing a trend to increase. In what concerns to our country, by early 80's there were some data showing important regional variations concerning IHD and CVD mortality. So, the aims of this study were to analyse the evolution of IHD and...
