An increasing body of palaeobotanical data demonstrates a series Pliocene and Pleistocene extirpations extinctions plant lineages in western Eurasia, which are believed to have been determined by the climatic properties their related East Asian North American sister lineages. We investigated diversity widespread northern hemispheric family, Fagaceae, during Late Portugal. found high Fagaceae co...
The article features the role of EU in Greater Eurasian Partnership (GEP), a common geo-economic area Eurasia proposed by Russian President Vladimir Putin at St. Petersburg Economic Forum 2016. author assessed prospect cooperation between EU, China, and Federation on bilateral level, including GEP concept. sees no premises for establishing present: interactions China Russia as part Belt Road In...
Sir Isaac Newton may be considered the first pre-Eurasianist thinker. My research of his unpublished manuscripts demonstrates that he maintained presence cultural unity Eurasian space. To prove it, elaborated so-called “Eurasian dictionaries.” They are symbolic dictionaries translating meaning into symbols and vice versa. As evidently showed, standing for most important religious political noti...
An update is provided of Northern Hemisphere (NH) spring (March, April) snow cover extent (SCE) over the 1922–2010 period incorporating the new climate data record (CDR) version of the NOAA weekly SCE dataset, with annual 95% confidence intervals estimated from regression analysis and intercomparison of multiple datasets. The uncertainty analysis indicates a 95% confidence interval in NH spring...
The National Centers for Environmental Prediction–National Center for Atmospheric Research (NCEP–NCAR) reanalysis is used to estimate time trends of, and analyze the relationships among, six indices of cyclone activity or forcing for the winters of 1949–99, over the region 208–708N. The indices are Eady growth rate and temperature variance, both at 500 hPa; surface meridional temperature gradie...
[1] Long-range transport of air across the European and Asian continents brings substantial quantities of ozone and other oxidants to northeast Asia from upwind sources over Europe and North America. This transport differs significantly from that over the Pacific and Atlantic Oceans because of weaker and less frequent frontal systems over the continent and because of weaker convective lifting o...
NW-tending faults in Central Iran are expected to represent dominant dextral components due to their orientation with respect to the northward motion of the Arabian Plate with respect to Eurasia. However, previously published works, as well as the focal mechanism solution of the area's earthquakes, indicate evidence of sinistral kinematic along the major faults in Central Iran. Here we present ...
به منظور تعیین پراکنش ویروس ایکس سیبزمینی طی سالهای 1389 و 1390، از مناطق کشت اصلی سیبزمینی در استان همدان شامل بهار، رزن و کبودرآهنگ بازدید و مجموعاً 456 نمونه برگی (تعداد 132 و 324 نمونه به ترتیب علائمدار و تصادفی) از 9 مزرعه جمع آوری شد. نتایج آزمون الایزا نشان دهنده آلودگی 42 نمونه تصادفی با ویروس ایکس سیب زمینی بود. میزان وقوع آلودگی به این ویروس به ترتیب کاهش در مناطق بهار (3/18%)، رزن...
