In Bulgaria there is a century-long tradition of radon measurements [8]. Since 1907 with hardly any interruption radon and later also radon progeny have been measured in mineral spas, in underground mines, in the human environment and in laboratory research. Experience from all these fields was gathered in the Faculty of Physics at St. Kliment Ohridski University of Sofia. Nowadays, exposure to...
Analyzing and evaluating the sensitivity of embedded systems to soft-errors have always been a challenge for aerospace or safety equipment designer. Different automated fault-injection methods have been developed for evaluating the sensitivity of integrated circuit. Also many techniques have been developed to get a fault tolerant architecture in order to mask and mitigate fault injection in a c...
Abstract Ionizing-radiation causes acute radiation syndrome leading to hematopoietic, gastrointestinal and cerebrovascular injuries. Substantial federal efforts have been made develop therapeutic radioprotectants for routine clinical use, however it remains a long-standing unresolved problem. We investigated population of mice that recovered from high-dose live normal lifespans. These elite-sur...
Today, with the rise of the private sector in space exploration, space missions are becoming more frequent than before. This in relation to the fact that modern electronics scale both faster and denser, the effects of radiation become a critical design requirement for fault-tolerance in on-board space computer systems. Radiation damage can be separated into two categories, Total Ionizing Effect...
Background: Ramsar, a northern city in Iran, lies on the coast of the Caspian Sea. This city has areas with some of the highest levels of natural radiation measured to date. The radon concentration in some areas of Ramsar is up to 3700 Bq m–3. On the other hand, due to high level of humidity, damp-proof barriers should be used in construction of new buildings in radon prone areas of this cit...
Mitigation and adaptation are the most important strategies in combating global climate change. It is expected that in a post Kyoto world industrialized countries have to engage in greenhouse gas abatement, and to support developing countries in adapting to climate change. Within the framework of a non-cooperative Nash game we analyze, whether funding adaptation is incentive compatible in the s...
Recent scientific advances have introduced the possibility of engineering the climate system to lower ambient temperatures without lowering greenhouse gas concentrations. This possibility has created an intense debate given the ethical, moral and scientific questions it raises. This paper examines the economic issues introduced when geoengineering becomes available in a standard two-period two-...
gamma rays pose enough energy to remove electrons from atoms of absorbing material including human body and adversely affect human health. the external exposure of human beings to natural environmental gamma radiation normally exceeds that from all man-made sources combined. therefore, we monitored gamma dose rate in indoor environments and estimated corresponding annual effective dose in selec...
[1] Understanding how a changing boreal fire regime is likely to influence regional climate requires detailed information about fire effects on the surface radiation budget. We used time series of satellite observations of surface albedo from 2000–2011 and fire perimeters since 1970 to study post-fire changes in surface net shortwave radiation along a latitudinal transect in central Canada. Fir...
More than 100 countries pledged to reduce agricultural greenhouse gas (GHG) emissions in the 2015 Paris Agreement of the United Nations Framework Convention on Climate Change. Yet technical information about how much mitigation is needed in the sector vs. how much is feasible remains poor. We identify a preliminary global target for reducing emissions from agriculture of ~1 GtCO2 e yr-1 by 2030...
