A system for obtaining respiratory flow rate waveforms, tidal volume, minute volume, respiration rate, inhalation time and exhalation time is described. The system is based on a microcomputer with analog-to-digital converter board. System software allows callibration, data acquisition and data analysis. Data can be obtained automatically at fixed time intervals. The system is inexpensive and reliable.
The coordinate change eigenvalues for the MacKay and van Zeijts period doubling renormalisation operator for bimodal 1 D maps are derived. They are found in numerical computations of the spectrum at all the periodic orbits of renormalisation of period up to five.
In 1970, Plummer introduced the notion of a well-covered graph as one in which every maximal independent set is a maximum. Here, Pink Ghd Straighteners Uk we study graphs in which there are exactly two sizes of maximal independent sets. A characterization of such graphs is obtained for graphs of girth eight or more.
A critical analysis of research methods in the published literature in the field of information science. Report on the results of the comparison made between a set of Ghd Online Approved Retailer Uk
430 articles published 1969–1971 and another set of 152 articles published in 1974. Overall findings indicate that while the amount of research reported is remaining stable, the methods have improved somewhat in 1974, as compared to earlier years.
