A total of 92 alleles were detected from 26 pairs of selected primers with 53. 68% of polymorphism. The alleles detected per locus were ranged from 2 to 8. On average,3. 54 alleles were amplified from per pair of primers. The similarity coefficients of the 8 varieties were in the range of 0. 729-0. 924.According to the genetic similarities based on UPGMA method,all materials were divided into two groups of Jinlan pomelo and Shatian pomelo at the similarity coefficient of 0. 738.展开更多

Adults of H. micans were collected using Neuston Net from the starboard side of R/V MIRAI on a fixed station at 8°S, 80°E, whereas those of M. histrio were collected from a small pond filled with a spring fresh water in Kochi (33°N, 133°E), Japan. Time in survival was measured in starved condition under several salinity conditions: 0‰, 2‰, 4‰, 6‰, 8‰, 9‰ and 10‰ for H. micans;0‰, 5‰, 10‰, 12.5‰, 15‰ for M. histrio. Half of adults were in coma due to lower salinity under 10‰ and time in survival was less than 10 hours under less than 4‰ for H. micans. Time in survival was half at 5‰ of 80 hours on average at 0‰ as a control and less than 10 hours at 10‰ or higher salinity for M. histrio. Relatively flexible osmo-regulation ability by H. micans would be related to wide variety of salinity condition of surface oceanic water, whereas very limited tolerance even to lower salinity of 5‰ may be permitted by the no chances to be exposed to brackish water in natural habitats of M. histrio. This study showed that salinity tolerance of Halobatinae species would reflect, directly, the salinity condition of their habitats.展开更多

A 85 （2012） 044102], we studied the Berry phase of the ground state and exited states in the Lipkin model. In this work, using the Hellmann-Feynman theorem, we derive the relation between the energy gap and the Berry phase closed to the excited state quantum phase transition （ESQPT） in the Lipkin model. It is found that the energy gap is approximately linearly dependent on the Berry phase being closed to the ESQPT for large N. As a result, the critical behavior of the energy gap is similar to that of the Berry phase. In addition, we also perform a semiclassical qualitative analysis about the critical behavior of the energy gap.展开更多

Both peoples cite the famous Mongolian blue spot, as well as the Mongolian Empire＇s close relations with the Koryo dynasty in the thirteenth and fourteenth centuries. However, it is undeniable that in recent years, Mongolia＇s relations with South Korea have grown much wider and deeper in scope. When it comes to multiculturalism a South Korea＇s overarching social phenomenon, tens of thousands of Mongolian expatriates are one of primary contributors to the first-ever trend throughout Korean history. Marriage migration of Mongolians to South Korea has increased since mid-1990s, in company with immigrant laborers, and became one of the primary contributors to the binational population movement, This paper deals with intertwining migration of Mongolian population to South Korea and describes characteristic of Korean-Mongolian binational marriage, using statistical data and other relevant researches.展开更多
