  • Biomedical engineering R&D: the Venezuelan experience

    Publication Year: 1992, Page(s):26 - 31
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1462 KB)

    Inefficient health care systems, shortage of resources, and a lack of proper understanding of the impact and relevance of health technology in Venezuela are examined. Biomedical engineering R&D, which is carried out by six groups spread around the country, is discussed, focusing on the impact of the above factors. The structure of the health care system in Venezuela is described, and the character... View full abstract»

    The activities of the applied bioengineering program in Bahia Blanca, Argentina, are described. The program's activities are discussed in terms of applied mechanics research and technological developments. Three areas of research are examined: (1) reduction of the vibrational and noise level in incubators for newborns; (2) analysis of the variation of frequency coefficients of a simplified bone-fr...

    The entropy, or amount of uncertainty, of a diagnostic hypothesis is defined and used to compute the possible hypothesis improvement when each unperformed test is assumed to be executed. This criterion permits objectively ranking such tests to guide the physician in making his next choice, to actually refine the current hypothesis. The procedure can be recurrently applied until the entropy of the ... View full abstract»

    The design and application of an apparatus for measuring pain threshold by controlling the conditions of an experiment carefully and measuring stimulus and response parameters precisely are described. Heat generated by an incandescent source, focused on a small area of the subject's forehead, was used as the stimulus to determine the cutaneous pain threshold. The equipment was in different experim... View full abstract»

    A comparison between the clinical engineering situation in Brazil and that found in some industrialized nations (including the US, Canada, and the UK) is drawn, highlighting possible future developments regarding health care technical service (HCTS) policy, human resources, and technology development. As a background, Brazil's economic development since 1960 is summarized. The Brazilian health car... View full abstract»

  • Angular levers and power in the human body

    Publication Year: 1992, Page(s):55 - 60
    Cited by:  Papers (1)

    The results obtained from observations and measurements, based on radiographic sequences, of the levers that operate in the rotations of some sectors of the human body around their natural fulcra (ankle, knee, elbow) are reported. They are based on rigorous application of the laws of physics to human movement, no matter how complex. The results show the economy and simplicity of design in the kine... View full abstract»

    A circuit patented by Kurt S. Lion in the 1950s, which essentially acts as a transducer, converting the changes of a variable capacitor into a DC voltage, is discussed. This circuit, which appears to have been forgotten, has definite advantages, especially as an efficient processing network for capacitive transducers. The authors offer a full qualitative and quantitative description (equations are... View full abstract»
