Establishment of Deep Ocean Circulation Driven by Deep-Water Production
Deep Ocean Circulation Driven Deep-Water Production
2009/1/9
A linear, two-layer baroclinic model of deep circulation driven by deep water production is formulated. In distinction to the Stommel-Arons model where a uniform middepth upwelling is prescribed, the ...
Herbaceous Plant Cover Establishment in a Barren Materials Quarry
Biodiversity soil analyses soil rehabilitation mining
2010/3/17
The ability to establish cover using grass and legume species without any soil preparation was studied in a barren materials quarry. The biodiversity indexes (Simpson) during the growing season as wel...
A new theory for the generation of the Tsugaru and Alboran gyres is proposed. The essence of the theory can be described as follows. Using the nonlinear reduced-gravity (shallow water) equations, it h...
Boundary Layer Control of Buoyant Coastal Currents and the Establishment of a Shelfbreak Front
Boundary Layer Control of Buoyant Coastal Currents and the Establishment of a Shelfbreak Front
2008/7/4
The bottom boundary layer exerts a powerful control over buoyant coastal currents that contact the bottom, providing a mechanism for trapping density fronts along isobaths. Recent observations suggest...
一种早期胚胎体外培养新方法的建立Establishment of a New Method for Early Embryo Culture in vitro
体外培养 套皿法 早期胚胎
2008/1/8
摘要
建立一种不依赖于液体石蜡的早期胚胎体外培养方法——套皿法，并比较了4种不同处理方法体外培养胚胎的效果。结果显示，采用套皿法进行胚胎培养，盖液体石蜡和不盖液体石蜡皿中的胚胎在各阶段的发育率差异不显著。与套皿法相比，用单皿微滴覆盖法(Brinster法)培养的胚胎在各阶段的发育率显著降低。不覆盖液体石蜡单皿中的胚胎则阻断于二细胞阶段。本实验设计的套皿法是一种有效的早期胚胎体外培养方法，为早期...
