Weather and tick borne viral encephalitis in the Czech and Slovak Republic
Střeštík, Jaroslav ; Mikulecký, M. ; Mikulecký Jr., M.
Cross-correlation of the annual incidence of tick borne encephalitis (TBE) in the Czech Republic (1965-2003) and Slovak Republic (1980-2004) with some external factors has been evaluated. The increase of the TBE is observed 1-3 years after the year with higher average air temperature. With the global warming the increase of the TBE is observed and they spread more to the North.
Solar spots, flares and geomagnetic activity: related to cerebral stroke?
Střeštík, Jaroslav ; Mikulecký, M.
Monthly numbers of cerebral infarctions dutiny 16 years wereas correlated with monthly values of solar and geomagnetic activity. There is a significant negative correlation between solar/geomagnetic aktivity and the incidence of cerebrál infarctions with a time shift of one year.
Possible external factors influencing the occurrence of heart tachyarrhythmia
Střeštík, Jaroslav ; Mikulecký, M.
The second author recorded during 24 years nearly 400 cases when he was attacked by heart tachyarrhythmia. This appeared during the years more often, in the last year as much as three cases in a month. Only weak dependence of arrhythmia attacks on the season or on the week has been found.
Natural and artificial variations in the natality in Slovakia
Střeštík, Jaroslav ; Mikulecký, M. ; Žirko, M.
Daily numbers of births in Slovakia 1996-2001 were taken into calculations. In the annual variation a trough occurs from October to December, and short sharp minima during holidays. In the spectrum only annual and 7-day period supplemented by their higher harmonics can be found. No trace of lunar variation has been bound.
Lengths of grapewine sprouts, air temperatures and heliogeophysical factors from the point of view of chronobiology
Střeštík, Jaroslav ; Mikulecký, M.
Series of sunspot numbers, indices of geomagnetic activity, mean air temperature in April and grapewine lengths measured to the 24th April were processed by power spectra and mutual coherences. Whereas spectra of sunspot numbers exhibit a pronounced peak at 11 yr, in spectra of other quantities more significant peaks occur.
