Solar ultraviolet radiation on the ground level of Isfahan
Introduction: Ultraviolet (UV) radiation affects human organs such as skin, eyes and immune system, as well as animals and plants. The main natural source of UV radiation is the Sun. To study the effects of solar UV radiation there is a need to quantify variations of solar energy received on the earth surface at different intervals. Materials and Methods: To measure UV radiation a broadband fib...
متن کاملCardiovascular events associated with proton pump inhibitors.
Coronary Artery Disease (CAD) patients to decrease the incidence of cardiovascular events.1 Above all, mucosal injuries associated with inhibition of prostaglandin synthesis, resulting in GI ulceration and bleeding, is a major side effect of the drug.1 Therefore, a concomitant use of Aspirin and Proton Pump Inhibitors (PPIs) has been approved for CAD patients to prevent mucosa associated disord...

متن کاملCan multiple shocks trigger ground level events?
A total of 16 Ground Level Events (GLE) occurred in solar cycle 23. These events, in which particle energies reach above 1 GeV/nuc, are the most energetic examples of Gradual Solar Energetic Particle (SEP) events. Over the past solar cycle, a great deal has been learned about these events observationally. However, the process by which particles are accelerated to these high energies is still pr...
متن کاملPolar Mesosphere Winter Echoes during Solar Proton Events
Thin layers of enhanced radar echoes in the winter mesosphere have been observed by the ESRAD 52 MHz MST radar (67° 53 ‘ N, 21 ° 06 ‘ E) during several recent solar proton events. These polar mesosphere winter echoes (PMWE) can occur at any time of day or night above 70 km altitude, whereas below this height they are seen only during daytime. An energy deposition / ion-chemical model is used to...
