چکیده بهینه سازی را می توان علم مشخص نمودن بهترین جواب برای یک مسئله که بصورت ریاضی تعریف شده است، بیان کرد. یکی از شاخه های اساسی بهینه سازی، برنامه ریزی غیرخطی است و یکی از زیر رده های برنامه ریزی غیرخطی، حل مسئله نامقید غیر خطی است. برای حل این مسئله روش های متنوعی ارائه شده است که می توان به روش گرادیان، نیوتن، شبه نیوتن، گرادیان مزدوج و... اشاره کرد. روش های شبه نیوتن، از مشهورترین روش ها...
Hereditary effects of radioactive fallout on gall-forming aphids and the subsequent recovery process near the Fukushima Daiichi Nuclear Power Plant
Even after 7 years of the nuclear accident that occurred in 2011 at Fukushima Dai-ichi power plant (F1NPP), high levels 137Cs have been detected ambient aerosols from some polluted areas Fukushima. Higher radionuclides were often observed atmosphere during and rain events. We presume biological processes such as fungal activity associated with higher relative humidity may be involved a possible...
On March 11, 2011 an unusually strong earthquake, now called the Tohoku earthquake, occurred off the north-eastern coast of Japan's main island, Honshu. While the earthquake caused some destruction, the ensuing tsunami about three quarters of an hour later largely destroyed numbers of towns and devasted cities such as Sendai. http://earthquake.usgs.gov/earthquakes/eqarchives/poster/2011/2011031...
The Fukushima Daiichi accident raises a fundamental question: Can science and technology prevent the inevitability of serious accidents, especially those with low probabilities and high consequences? This question reminds us of a longstanding challenge with the trans-sciences, originally addressed by Alvin Weinberg well before the Three Mile Island and Chernobyl accidents. This article, revisit...
BACKGROUND On March 11, 2011, a magnitude 9.0 earthquake occurred off of Japan's Pacific coast, which was followed by huge tsunamis that destroyed many coastal cities in the area. Due to the earthquake and subsequent tsunami, malfunctions occurred at the Fukushima Daiichi (Fukushima I) nuclear power plant, resulting in the release of radioactive material in the region. While recent studies have...
BACKGROUND Following the Great East Japan Earthquake on March 11, 2011, the nuclear disaster at the Fukushima Daiichi Nuclear Power Plant has continued to affect the mental health status of residents in the evacuation zone. To examine the mental health status of evacuee after the nuclear accident, we conducted the Mental Health and Lifestyle Survey as part of the ongoing Fukushima Health Manage...
After the Fukushima Daiichi nuclear incident in 2011, radiation contamination of the affected area raised public health concerns about internal radiation exposure. Internal radiation exposure screening using a whole body counter (WBC) (Fastscan Model 2251, Canberra Inc, Meriden, CT) has been performed for the affected residents in Soma City, 40 km north of the Fukushima Daiichi nuclear power pl...

On March 11, 2011, a huge tsunami caused by the Great East Japan Earthquake destroyed all the electrical power facilities in the Fukushima Daiichi nuclear power plant. As a result, the reactors were badly damaged, and radioactive particles were widely scattered in the surrounding areas. In order to study the behavior of the radioactive particles emitted from the Fukushima Daiichi nuclear power ...
