The forms and limits of medical ethics
Social Science & Medicine, 1994 As medical ethics has evolved over the past several decades, it has come to be regarded as a domain of applied ethics, that is, the application of a rationally based, philosophical theory to moral problems in health care. But an array of difficulties arise in the attempt to apply general moral theories or norms to concrete problems, difficulties that ...

On the Determination of Forming Limits in Polycarbonate Sheets [PDF]
Materials, 2020 By proposing an adaptation of the methodology usually used in metal forming, this paper aims to provide a general procedure for determining the forming limits, by necking and fracture, of polymeric sheet. The experimental work was performed by means of Nakajima specimens with different geometries to allow to obtain strains in the tensile, plane ...
