Seasonal and diurnal flight patterns of the invasive walnut twig beetle, Pityophthorus juglandis, were assessed between 2011 and 2014 in northern California, USA in the context of the effects of ambient temperature, light intensity, wind speed, and barometric pressure. Pityophthorus juglandis generally initiated flight in late January and continued until late November. This seasonal flight coul...

AIM To evaluate whether objective data could be obtained regarding internal pressure conditions of a molar tooth with canals prepared but not filled exposed to reduced barometric pressures that could be experienced by aircrew. METHODOLOGY The root canals of five mandibular molars were prepared but not filled. Root apices were sealed with a resin-modified glass-ionomer liner and root surfaces ...

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,...
