We hypothesized that weather and space weather conditions were associated with the exacerbation of essential hypertension. The study was conducted during 2009-2010 in the city of Kaunas, Lithuania. We analyzed 13,475 cards from emergency ambulance calls (EACs), in which the conditions for the emergency calls were made coded I.10-I.15. The Kaunas Weather Station provided daily records of air tem...

focused on space efforts and the appearance of commercial jet aviation, medical subjects, which formerly concerned only aviation medicine specialists, now have become of considerable interest to all physicians. One example of the degree of interest has been the establishment of the Committee on Aerospace Medicine by the American College of Chest Physicians. Much attention has been given to the ...

Changes in barometric pressure may be related to how people feel and how they perform. It is known that a decrease in the partial pressure of oxygen in the ambient air, which results from high altitude or hypoxia, causes decreased oxygen saturation in the blood and related performance decrement (1). Conversely, it has been shown that an increase in the partial pressure of oxygen in ambient air,...

The most recent advances in silicon micromachining technology have given rise to a variety of low-cost pressure sensor applications and solutions. Certain applications had previously been hindered by the high-cost, large size, and overall reliability limitations of electromechanical pressure sensing devices. Furthermore, the integration of on-chip temperature compensation and calibration has al...

There are a number of variables that are correlated with land elevation. Land elevation, and in particular, its surrogate variables such as natural background radiation, can be studied in relation to cancer rates. The present ecological study focuses on three such variables correlated with land elevation: natural background radiation (NBR), oxygen concentration (OC), and barometric pressure (BP...
