It has been proved that there are no real hypersurfaces satisfying RA =0 in non-flat complex space forms. In this paper we prove that the same is true in the case of CR submanifolds of maximal CR dime...
Quantifying saline groundwater flow into a freshwater lake using the Ra isotope quartet: A case study from the Sea of Galilee (Lake Kinneret), Israel
Quantifying saline groundwater flow freshwater lake

We investigated the Ra isotope quartet in order to quantify the discharge of saline groundwater into a
freshwater lake. The activities of 226Ra, 228Ra, 223Ra, and 224Ra were measured in the Sea of Ga...

在中子剂量仪表刻度和中子剂量计算中经常遇到单位注量中子与比释动能、吸收剂量、剂量当量之间的换算关系。它们之间的数值关系通常称为中子注量-剂量换算系数。在《放射防护规定》中规定职业放射性工作人员最大容许剂量当量为每年5雷姆。同时又对2.5毫雷姆/小时对应的中子通量(中子/厘米~2·秒)进行了规定(见附表1第7栏)。国际辐射防
Partition coefficients of Ra and Ba in calcite

应用mRNA差异显示技术寻找调控白腰纹鸟前脑发声控制神经核RA性双态性发育的基因
白腰纹鸟 性双态性 RA mRNA差异显示 发声-控制核团
font style='font-size:12px;'>
2007/12/17
鸣禽的发声行为及其前脑发声控制核团存在显著的性双态性,这种性双态性是在发育过程中逐步建立起来的。鸣禽白腰纹鸟35日龄(P35)前,雌、雄鸟前脑发声控制神经核RA(Robust nucleus of arcopallium) 不存在性别差异;到45日龄(P45)时,雌、雄鸟RA体积已经出现了显著的差异。推测这种神经结构的性双态性的形成与各种基因的不同时空表达有关。本实验以发育不同阶段(P35时的雌性...
