The aim of the study is to study links between time, Solar (SA), Geomagnetic (GMA) and Cosmic Ray (CRA) (Neutron) activity and monthly deaths distribution from all and six subgroups of death causes in years 1990-2009 for ad-ditional clarification of the role of exogenic factors in human homeostasis. Methods and patients: 850304 deaths (44657 men, 400647 woman) and 6 subgroups were studied in 240 consecutive months in the Re-public of Lithuania in relation to the months of year (1 - 12), 4 indices of SA (Sunspot number and Solar Flux), 3 indices of GMA (planetary and regional for the Middle Latitudes), and CRA described by Neutron activity on the Earth's surface-remains of crushed atoms in the high space levels and measured by Imp/min. The cosmophysical data came from Space Science Institutions in the USA, Russia and Finland. Statistical analysis of the results for monthly comparison are presented. Results: It was a significant and inverse relationship of monthly deaths number for both gender with CRA and SA, less with GMA. It was a significant drop of deaths from IHD and sui-cides. Oncology deaths also show similarity in their timing with other groups. A strong inverse rela-tionship was seen in monthly death number from IHD and Stroke. (r = -0.76, p < 0.0001), woman show more seasonality in death's distribution. Most deaths show annual rhythm with acrophase in February. Only Suicide pick appears in the summer months. Conclusion: at the beginning of the XXI century, in addition to accepted risk factors, environmental physical activity is linked to timing of death. Cosmic Ray (Neutron) activity is one of the main regulators of this relationship. Stroke related deaths are becoming a more prominent cause in the collection of car-diovascular deaths. Suicide related deaths show a drop, possibly related to a massive trend for immi-gration in the high risk group of the population. The precise mechanism of action of the studied physical factors needs additional studies.展开更多

In recent years, several medical phenomena were described in inverse distribution by time with GMA. Also a concurrent to GMA and solar activity force-cosmic ray activity (CRA) and closely related high energy neutron and proton fluxes are studied as a forces dominating at low GMA and solar activity in relation to considered medical events. The aim of this study was to explore the distribution of some important medical events on days with “Zero” GMA levels, accompanied by high CRA (neutron activity). Medical event data of the Grand Baku region (more than 3 mln inhabitants), Azerbaijan, with daily distribution on the time 1 Dec. 2002-31 Dec. 2007 was compared to daily GMA Kp indices in general (Kp > 0, 1837 days) and 34 days daily GMA indices Kp = 0. Daily CRA data was also compared using neutron monitoring data from two stations. Daily averaged data and their standard deviations on the mentioned GMA levels were compared and statistical significance was established. Results revealed a significant rise in the number of emergencies (n = 1,567,576) and total deaths number (n = 46,360) at the days of “Zero” GMA level. These days were accompanied by significant rise of CRA (neutron activity). For Sudden Cardiac Deaths (SCD, n = 1615) and cerebral stroke (CVA, n =10,054) the increase achieved strong trend to significance level. Acute Myocardial Infarction occurrence (morbidity) and trauma were also absolutely more registered at days with “Zero” GMA level, despite the small number of such days. The average Infection numbers show an inverse relationship with absolutely high registry at the “Zero” GMA level days. Study linking environmental physical activity levels and the human medical data shows that geomagnetic field variations accompanied by the increased level of cosmic ray activity, can have either direct or indirect adverse effects on human health and physiology, even when the magnitude of the geomagnetic field disturbance is extremely small or even is equal to zero. On days of “Zero” daily Kp indices describing Geomagnetic Activity, accompanied by high Cosmic Ray Activity (neutron activity), more medical emergencies and total death number (daily) occurred. Sudden Cardiac Deaths and Cerebral Stroke numbers show a strong trend to significant rise. Absolute increase of number of Acute Myocardial Infarction and less Infections, not achieving statistical significance, was also observed. These results are additional data for considering Cosmic Ray Activity (neutron activity) as an additional factor involved in time distribution of human medical events.展开更多

Concomitantly a number of studies were published demonstrating connections of many cardiac events with Space Weather Activity-Solar, Geomagnetic, Cosmic Ray (Neutron) activity levels. The aim of this study was to study links of timing of hospital admissions for HF with season and space weather components. Patients and Methods: monthly admissions of male and female patients for HF in two hospitals of Rabin Medical Center for years 2000-2012 were the subject of the study. 76,601 patient were included, 42,293 men, 34,308 woman. The cosmophysical data from USA, Russia and Finland were used. Results: Monthly average number of admissions for HF: 491.0 ± 82.4, 271.1 ± 46.75 for men and 219.9 ± 39.8 for woman. Gender admissions strongly correlated. Monthly admission for HF number differed by 2.2 - 2.5 times. Minimal admissions were in August, September;maximal—in January, February, December and March (according to numbers). It was a significant inverse correlation of monthly HF admissions with monthly solar activity and GMA indices and correlation with CRA (neutron) activity. Conclusion: Monthly admissions number for HF is fluctuated by season of the year, depending on gender and related to monthly solar and Cosmic Ray (Neutron) activity level. Gender differences in HF exacerbation may be a component explaining gender differences in longevity.展开更多

A global rearrangement is expected by the magnetic reconnection that requires explaining the giant SGR flares. In this paper we propose two regions of flares: preflare on the surface of magnetar and main burst at a distance of light cylinder radius. Acquiring the maximum potential drop on the magnetar surface, adopting space charge limited flow model, and using magnetic field B ≈ 1015 G, the luminosities of flare energies release for the preflare phase and main burst phase are found to be in the order of 1041 erg·sˉ1 and 1044 erg·sˉ1 respectively, conforming to magnetar burst energy and flare temperature is determined by considering black body radiation.展开更多
