Research on single hole heat transfer power of ground source heat pump system
Ground source heat pump Monitoring Heat transfer power Thermal response test
2018/3/23
In this paper, the single hole heat transfer power of the ground source heat pump system in Hengshui is compared with data gained from thermal response test. The results show that maximum monitoring d...
Understanding the Role of the Biological Pump in the Global Carbon Cycle:An Imperative for Ocean Science
Biological Pump Global Carbon Cycle Ocean Science
2015/7/20
Anthropogenically driven climate change will rapidly become Earth's dominant transformative influence in the coming decades. The oceanic biological pump—the complex suite of processes that results in ...
Augmenting the Biological Pump:The Shortcomings of Geoengineered Upwelling
Augmenting the Biological Pump Geoengineered
2015/7/20
The ocean is the largest reservoir of mobile carbon over decadal to centennial time scales, absorbing approximately 41% of cumulative anthropogenic CO2 emissions (Sabine and Tanhua, 2010). Various geo...

samples in the Sho river fan, Toyama, northern part of central Japan, were analyzed ...
Evaluation of tractor biodegradable hydraulic fluids on the basis of hydraulic pump wear
test bench cleanliness level flow efficiency agricultural tractor fluid temperature
2014/2/24
Two types of biodegradable hydraulic fluids (HEES and HEPR) with the mineral oil-based hydraulic fluid (HV) were
compared. The tests were performed using a test bench. During the tests with a tracto...
Diagrammatic pump-probe approach to coherent backscattering of laser light by cold atoms: Double scattering revisited
Diagrammatic pump-probe coherent backscattering of laser light cold atoms Double scattering revisited Atomic Physics
2012/4/20
We present a diagrammatic derivation of the coherent backscattering spectrum from two two-level atoms using the pump-probe approach, wherein the multiple scattering signal is deduced from single-atom ...
The “salt wedge pump”: Convection-driven pore-water exchange as a source of dissolved organic and inorganic carbon and nitrogen to an estuary
salt wedge pump Convection-driven pore-water exchange source of dissolved organic inorganic carbon nitrogen to an estuary
2014/4/4
Hypoxia and anoxia in coastal waters have typically been explained by the respiration of sinking organic matter associated with nutrient over-enrichment and phytoplankton blooms. Here, we assess wheth...

Effect of a plasma grating on pump-probe experiments near the ionization threshold in gases
plasma pump-probe experiments ionization threshold gases
2011/8/4
Abstract: Calculations are performed of the phase shift caused by the spatial modulation in the plasma density due to interference between a strong pump pulse and a weak probe pulse. It is suggested t...

electron jet pump Venturi effect of a Fermi liquid
2010/11/19
A three-terminal device based on a two-dimensional electron system is investigated in the regime of nonequilibrium transport. Excited electrons scatter with the cold Fermi sea and transfer energy and ...
Forcibly driven coherent soft phonons in GeTe with intense THz-rate pump fields
coherent soft phonons GeTe intense THz-rate pump fields
2010/11/23
We propose an experimental technique to generate large amplitude coherent phonons with irradiation of THz-rate pump pulses and to study the dynamics of phase transition in GeTe ferroelectrics.When a s...
Reply to comment by K. M. Lau and K. M. Kim on '"Elevated heat pump' hypothesis for the aerosol-monsoon hydroclimate link: 'Grounded' in observations?"
K. M. Lau and K. M. Kim Elevated heat pump aerosol-monsoon hydroclimate link in observations
2014/5/20
Lau and Kim‟s [2011, hereafter LK11] defense of the Elevated Heat Pump (EHP) hypothesis is weak. Nigam and Bollasina [2010, hereafter NB10] have assessed the viability of the EHP hyp...
Carbon sequestration and zooplankton lunar cycles: Could we be missing a major component of the biological pump?
Carbon sequestration zooplankton lunar cycle
2014/4/17
The plankton outburst during the so-called late winter bloom in subtropical waters was studied in relation to
lunar illumination in the Canary Island waters. Nutrient enrichment by mixing and dust de...
