Large-scale scientific research often relies on the collaborative use of Grid and e-Science infrastructures that provide computational or storage related resources. One of the ideas of these modern infrastructures is to facilitate the routine interaction of scientists and their workflows with advanced problem solving tools and computational resources.

In a 3-year follow-up we have investigated random samples of young men (initial age 20 to 24 years) by means of the modified BMRC questionnaire and maximal expiratory flow-volume curves. The participation in the second survey was relatively poor (51.9 p.c.). The lung function data of asymptomatic non-smokers were in good accordance with reference values of(More)
In an epidemiological study a random sample (1,554 males aged 35 to 54 years) of the population of a hydrogen chloride air-polluted area was investigated by means of the modified MRC questionnaire and maximal expiratory flow-volume curves. The MEF-values were dependent on age and height. We stated no significant differences between potash miners and the(More)
In a 4-year follow-up we have measured the maximal expiratory flow-volume curve in a random sample of the population of a hydrogen chloride air-polluted area. At the first investigation the pressure transducer of our pneumotachograph had shown an unsatisfactory frequency characteristic. Therefore the initial flow of the flow-volume curve (PEF and MEF 75)(More)

For reduction the working extent in measurement and classification of flow-volume curves a device was developed which calculates and indicates digitally the maximal expiratory flow values PEF, MEF 75, MEF 50 and MEF 25 directly from the flow in forced expiration. We have used an approaching calculation method whereby the expense of realization was low. By a(More)
