Regional Differences in the Role of Eddy Pumping in the North Atlantic Subtropical Gyre: Historical Conundrums Revisited
Eddy Pumping Historical Conundrums Revisited
2015/7/20
The vast subtropical regions of the ocean account for at least 30% of the carbon export to the deep ocean. It is predicted that these regions will get larger as a consequence of global warming. Tradit...
Pore-water exchange driven by tidal pumping causes alkalinity export in two intertidal inlets
intertidal inlets idal pumping
2014/10/16
Carbon (C) and alkalinity export from two adjacent intertidal inlets with different terrestrial inputs was
investigated. One inlet receives a small creek from an agriculturally dominated catchment, l...
Gyroscopic Pumping in the Solar Near-Surface Shear Layer
Gyroscopic Pumping Solar Near-Surface
2011/9/29
We use global and local helioseismic inversions to explore the prevailing dynamical balances in the solar Near-Surface Shear Layer (NSSL). The differential rotation and meridional circulation are inti...

Abstract: We determined the gas-flow reduction factor of the second forward Differential Pumping Section (DPS2-F) for the KATRIN experiment using a dedicated vacuum-measurement setup and by detailed m...
Development in the Scattering Matrix Theory: From Spin-Orbit-Coupling Affected Shot Noise to Quantum Pumping
Scattering Matrix Theory Spin-Orbit-Coupling Affected Shot Noise Quantum Pumping
2010/11/23
The review chapter starts by a pedagogical introduction to the general concept of the scattering theory: from the fundamental wave-function picture to the second-quantization language, with the aim to...
Nuclear spin pumping and electron spin susceptibilities
Nuclear spin pumping electron spin susceptibilities
2010/11/23
In this work we present a straightforward formalism to evaluate the nuclear spin dynamics driven by hyperfine interaction with non-equilibrium electron spins. To describe the dynamics up to second ord...
Coherent control of the cooperative branching ratio for nuclear x-ray pumping
Coherent control cooperative branching ratio nuclear x-ray pumping
2010/11/11
Coherent control of nuclear pumping in a three level system driven by x-ray light is investigated. In single nuclei, the pumping performance is determined by the branching ratio of the excited state p...
Many theoretical and laboratory studies predict H2 to be formed in highly excited ro-vibrational states. The consequent relaxation of excited levels via a cascade of infrared transitions might be obse...

2009/10/30
In the Egebjerg area, near Horsens, several aquifers consisting of glacial outwash material deposited in a glacial eroded buried valley in the Tertiary formation have been encountered.
The lowest of ...
When a test pumping from an artesian aquifer has been performed, the result
will often exibit a more or less confusing variety of features. The reason for
this may, of course, be that the geological...
