Work load in general practice.
ALTHOUGH SEVERAL STUDIES HAVE ALREADY been made on this subject, e.g. Bradford Hill (1951), Fry and Dillane (1964), College of General Practitioners (1965), our information is far from complete, and this quantitative study in a relatively large list, outer suburban London practice may fill some of the gaps. At the same time the value to me has been to highlight the inefficiency of conventional ...
متن کاملOxygen consumption during constant-load exercise.
Previous investigators have reported that oxygen consumption (VO2) continues to rise after the initial 2- to 3-min transient period of exercise when work exceeds approximately 60% of VO2 max. The purpose of this investigation was to examine the possible causes of this slow rise in VO2. Eighteen subjects exercised for 20 min at 65% and at 80% of VO2 max on the bicycle ergometer. VO2, ventilation...
متن کاملEuler’s Constant: Euler’s Work and Modern Developments
This paper has two parts. The first part surveys Euler’s work on the constant γ = 0.57721 · · · bearing his name, together with some of his related work on the gamma function, values of the zeta function, and divergent series. The second part describes various mathematical developments involving Euler’s constant, as well as another constant, the Euler–Gompertz constant. These developments inclu...
متن کاملMechanical load on the ventilatory muscles during an incremental cycle ergometer test.
An incremental cycle ergometer test performed with a total of 40 healthy subjects (25 male, 15 female) was used to study the mechanical load on the ventilatory muscles. The parameters for the mechanical load on the ventilatory muscles are the time integral of the oesophageal pressure and the mean oesophageal pressure change per time unit (dPoe/dTI) of each breathing manoeuvre. The pressure-time...
متن کاملClinical chemistry work-load control factors.
ORK-LOAD CONTROL FACTORS in clinical laboratories are not available in the literature. Business engineering and manpower-study methods are not readily applicable to laboratory work in which varied human elements exist. The remarkable variety of methods, choice of technics, personal viewpoints, lack of contacts, and few chances for direct comparison with the work of others in the field also make...
