the main driving force of the earth atmospheric system is solar radiation. radiation flux determines the surface temperature and impacts life on the earth through photosynthesis. a quantitative knowledge of the earth radiation field is important to evaluate the atmosphere–surface interactions and the global hydrological cycle. various atmospheric radiative transfer models have been proposed in ...
Improved survival for haemodialysis patients has been reported for synthetic, high-flux biocompatible membranes. The reported data fail to answer the question whether improved survival is related to an effect of enhanced biocompatibility or to increased clearance of larger molecular species of putative uraemic toxins. A retrospective analysis of 715 patients treated by continuous haemodialysis ...
Heat transfer coefficient in nucleate pool boiling near critical heat flux at least one orderhigher than the convectional heat transfer modes. In this paper, an experimental setup isdesigned and fabricated to investigate the mechanism of heat transfer from boiling surface tobulk liquid near critical heat flux. The images of pool boiling near the high heat flux regionreveals that the individual ...
In this investigation, the AISI 2205 duplex stainless steel was welded in the form of bead on plate by A-TIG process with different amount of the ZrO2 and TiO2 activated fluxes. The results of the visual inspection showed that the specimen with 50% ZrO2 and 50% TiO2 activated flux, had the lowest face width and the specimen with contains 90% ZrO2 activated flux, had the highest penetration dept...
two-dimensional euler equations have been solved on an unstructured grid. an upwind finite volume scheme, based on roes flux difference splitting method, is used to discretize the equations. using advancing front method, an initial delaunay triangulation has been made. the adaptation procedure involves mesh enrichment coarsening in regions of flow with high low gradients of flow properties, acc...
The understanding of the origin of 1/f magnetic flux noise commonly observed in superconducting devices such as SQUIDs and qubits is still a major unsolved puzzle. Here we discuss the possibility that a significant part of the observed low-frequency flux noise measured in these devices is ultimately seeded by cosmological fluctuations. We consider a theory where a primordial flux noise field le...
The Narrow-line Seyfert I galaxy, 1H0707-495, has been well observed in the 0.3– 10 keV band, revealing a dramatic drop in flux in the iron Kα band, a strong soft excess, and short timescale reverberation lags associated with these spectral features. In this paper, we present the first results of a deep 250 ks NuSTAR observation of 1H0707-495, which includes the first sensitive observations abo...
