The National Institute for Scientific Research (INIC): Pathway and Influence in Portuguese Science Policy (1976-1992)

Abstract

My Ph.D research project aims at writing the history of the Portuguese National Institute for Scientific Research (Instituto Nacional de Investigação Científica, INIC) (1976-92). Although INIC is an important institutional actor in the development of the Portuguese scientific system, it has been mostly absent from the history of the Portuguese institutions of science policy. INIC was founded after the Carnation Revolution of 25 April 1974 in a context in which institutional coordination of scientific research had already become a priority. The political instability of the post-revolutionary period, together with the expansion of the scientific system, resulted in institutional tensions and conflicts involving the scientific community, the higher education community, and other institutions tangent to INIC, that led to its extinction in 1992. Based on INIC’s archive and complemented by secondary sources and interviews, this project proposes to bring this institution into the historical narrative of the Portuguese institutions of science policy.

Fatigue Design and Prevention in Movable Scaffolding Systems

Abstract

The Movable Scaffolding System (MSS) is a heavy construction equipment used for casting situ of concrete bridge decks. In the past decades, MSSs have become increasingly complex and industrialized, enlarging its span ranges, incorporating auxiliary elevation machinery and increasing productivity. The tendency nowadays is for strong reutilization and the notion of MSS as a disposable or temporary structure is somehow reductive. The main structure of MSSs may be potentially exposed to fatigue, usually characterized by low number of cycles with significant stress amplitude. Fatigue may be prevented through adequate design; judicious selection of materials; demanding quality control and implementation of robust inspection and maintenance plans.
