the frame of the geochemical monitoring of seismicity mainly aimed at deepening the relationships between active seismotectonics and fluid geochemistry, i.e. earthquake prediction, a 222 Rn study was ...
In order to obtain information on the hydrological signature of rivers during and after heavy rain events, small catchment areas are selected as experimental sites. Hydrograph separations based on en...
Outline • Stochastic wave equations on Rn. • Random attractors theory. • Random absorbing sets for wave equations. • Pullback asymptotic compactness. • Existence of ...
The afforestation of agricultural lands was carried out under different site and ecological conditions, including lower and medium elevated localities. The present study documents the rapidity of accu...
Four theoretical growth functions, Mitscherlich, Logistic, Gompertz and Korf functions, were applied to the growth data on dbh and tree height of individual Eastern White Pine (Pinus strobus) trees to...
National calls for a better-educated nursing workforce are proliferating. The Institute of Medicine (IOM) challenged the nursing profession by setting the goal of having 80% of the nation's nurses pre...
This study describes approaches to create surface maps of radon in groundwater based on measurements of radon ( 222 Rn) in drilled bedrock wells at unevenly distributed sites and uranium bedrock m...
Mat\'ern's hard-core processes are valuable point process models in spatial statistics. In order to extend their field of application, Mat\'ern's original models are generalized here, both as point pr...
为了明确肉质相关基因氟烷基因(Hal)、酸肉基因(RN)和脂肪肥胖相关基因(FTO)在国内外不同猪种群体间的遗传变异特性,本研究以大约克、长白、杜洛克和金华猪等猪种群体为研究对象,应用PCRRFLP技术分别检测了Hal、RN和FTO基因的多态性,并分析了FTO基因上2个多态位点g.276G>T和c.594C>G的遗传变异情况。结果表明:(1) 在杜洛克猪中发现了Hal的基因型HalNHaln,其...

阐述了以RN不育细胞质为基础选育的细胞质雄性不育系和恢复系的类型。在大量测交以及预备试验的基础上,选择具有代表性的9对不育系和相应的保持系以及10个恢复系,进行不育系与所有保持系之间,以及不育系与所有恢复系之间所有可能的杂交。对不育系与恢复系杂交的F1,依据花粉败育率分为3类以表示恢复度,A类:败育率0~10%,B类:败育率11%~60%,C类:败育率61%以上。再依据这3类的分布情况和恢复谱,对...
利用协变反常取消法研究一种类RN黑洞的霍金辐射.结果表明,为了在量子水平上保持有效场的广义协变性和规范不变性,类RN黑洞的出射波的电荷总通量和能量总通量必须与一个具有相应化学势和霍金温度的(1+1)维黑体辐射的总通量相等.该结论支持了Robinson等人的观点,同时又使其在静态条件下得到了扩展.
The article deals with the evolution of Czech monetary theory during the nineties of the last century. At that time the Czech monetary economists were interested in two following problems: the pract...
用推转壳模型在多维形变空间系统研究了Rn-Th偶偶核的基态性质及高自旋情形下的性质, 其中选取的形变自由度为β2, β3, β4和β5. 计算结果很好的再现了实验提取的转动惯量值. 势能面的研究表明, 随中子数的增加, 基态形状由近球形(N≈130)逐渐演变为八极形变(N≈136)后又发展成为稳定的四极形变(N≥140). 推转计算表明Rn-Th偶偶核的八极形变非常软, 在推转到高自旋情形下, 逐...
[ 目的] 系统准确地了解RN 基因在外来猪种中分布, 制定科学合理的嘉兴养猪业育种计划。[ 方法] 通过PCR- RFLP 技术对嘉兴地 区主要外来猪种长白猪23 头、杜洛克猪21 头、大约克猪19 头进行RN 基因检测。[ 结果] 结果表明:3 个品种基因型均为rn/ rn, 未出现RN/ rnRN/ RN 型基因。[ 结论] 该检测结果为嘉兴地区主要外来猪种资源合理开发利用提供了理论依...
