Further studies on a theory of the ballistocardiogram.
IN THIS THEORY of the normal human longitudinal ballistocardiogram we shall attempt to relate the record, in quantitative terms, to the events in the circulation that we believe to be its genesis. The variables concerned here fall into three groups: those concerned with the performance of the heart as a pump; those concerned with the position and elastic properties of the vessels that contain t...

متن کاملThe normal ballistocardiogram.
The use of ballistocardiography in clinical practice has been greatly simplified by the introduction by Dock and Taubman (1949) ofthe direct pick-up which can be used in home or hospital. Each type of instrument has its own physical characteristics, and criteria for normality have to be defined for each. Brown et al. (1952) working with the high-frequency table ballistocardiograph emphasized th...
متن کاملCalibration of the direct ballistocardiogram.
A simple method of calibrating the amplitude of the direct ballistocardiogram, utilizing a standard external force to the body, is described. Such a method tends to neutralize many of the variables in apparatus alignment and sensitivity, and provides a basis for comparison of amplitudes in the same and different subjects. Normals of different age groups wvere studied and the contrast waith abno...

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
