A current scenario to explain much of the atmospheric CO2 increase during the Glacial to Holocene climate transition requires the outgassing of a deep, old oceanic CO2 reservoir thought to be located in the Southern Ocean. In this scenario, CO2-rich and 14C-depleted subsurface Antarctic-sourced water, ventilates the thermocline where it is purged to the atmosphere in the equatorial regions, a v...

after the collapse of bipolar system in the world, different views and theories expressed by the scholars and thinkers about the future of the world and international system. one of them is the theory of “ the clash of civilizations” which was propounded in 1993 by the samuel huntington, the director of j.m.olin institute for strategic studies in harvard uni-versity. this theory caused some anx...

Recent development has identified the benefits of using hyper-temporal satellite time series data for land cover change detection and classification in South Africa. In particular, the monitoring of human settlement expansion in the Limpopo province is of relevance as it is the one of the most pervasive forms of land-cover change in this province which covers an area of roughly 125 000km. In th...

[1] Analyses of global climate from measurements dating back to the nineteenth century show an ‘Atlantic Multidecadal Oscillation’ (AMO) as a leading large-scale pattern of multidecadal variability in surface temperature. Yet it is not possible to determine whether these fluctuations are genuinely oscillatory from the relatively short observational record alone. Using a 1400 year climate model ...

being on the right paththe 1st issue of the iranian journal of radiation research (ijrr) was published two years ago (june 2003). this journal was initiated to bring together the various disciplines of radiation oncology, radiation biology, medical physics, nuclear medicine and other related subjects to intensify the dialogue between basic and clinical researchers especially those working in ir...

Until recently, studies on films from colonial Korea in the Japanese empire had to rely primarily on secondary texts, such as memoirs, journal and newspaper articles, and film reviews. The recent discovery of original film texts from archives in Japan, China, Russia, and elsewhere and their availability on DVD format, prompted an important turning point in the scholarship. However, juxtaposing ...

the iranian journal of radiation research (ijrr) is now in the eighth year of publication. this journal is the mouth piece of shared idea of dr shahram akhlaghpoor and me, which was established way back in 2002. at that time the main emphasis of the founder members was to make the subject of radiation research attractive and interesting especially for combating cancer and risk assessment. the d...
