New observations of the vertically integrated CO2 mixing ratio, 〈CO2〉, from ground-based remote sensing show that variations in 〈CO2〉 are primarily determined by large-scale flux patterns. They therefore provide fundamentally different information than observations made within the boundary layer, which reflect the combined influence of large-scale and local fluxes. Observations of both 〈CO2〉 an...
[1] The physical and biological processes controlling surface mixed layer pCO2 and O2 were evaluated using in situ sensors mounted on a Lagrangian drifter deployed in the Atlantic sector of the Southern Ocean (∼50°S, ∼37°W) during the austral fall of 2008. The drifter was deployed three times during different phases of the study. The surface ocean pCO2 was always less than atmospheric pCO2 (−50...
The atmospheric deposition of polybrominated dibenzo-p-dioxins and dibenzofurans (PBDD/Fs) was investigated at four locations in different suburban and urban functional districts of Guangzhou City. The annual deposition fluxes of total PBDD/Fs (eight 2,3,7,8-substituted tetra- to hexa-BDD/Fs) were in the range of 36-51 (mean 46) pg m(-2) day(-1), and the corresponding TEQ fluxes were estimated ...
The local concentrations of the two fluids within a mixing layer produced by an interfacial instability are determined by their individual continuity equations. Solution of these equations requires constitutive relations for the local mass fluxes of the two fluids. We derive explicit analytical expressions for these fluxes in planar incompressible mixing layers characterized by a single integra...
We present observations of the global emission of a sample of spiral and irregular galaxies in the Virgo cluster and theComa supercluster. These observations have beenmadewith the camera ISOCAM on board the Infrared Space Observatory, through two broad filters centered respectively at 6.75 and 15.0 μm. The corresponding fluxes are corrected for the stellar contribution in order to obtain the pu...
The effects of three common tree species – Scots pine, Norway spruce and silver birch – on leaching of dissolved organic carbon and dissolved nitrogen were studied in an experimental forest with podzolised soils in southern Sweden. We analyzed soil water collected with lysimeters and modeled water fluxes to estimate dissolved C and N fluxes. Specific UV absorbance (SUVA) was analyzed to get inf...
The balance of K+, Na+, and Cl– fluxes across the cell membrane with the Na+/K+ pump, ion channels, and Na+K+2Cl– (NKCC) and Na+–Cl– (NC) cotransport was calculated to determine the mech anism of cell shrinkage in apoptosis. It is shown that all unidirectional K+, Na+, and Cl– fluxes; the ion chan nel permeability; and the membrane potential can be found using the principle of the flux balance ...
An important challenge in microbial ecology is to infer metabolic-exchange fluxes between growing microbial species from community-level data, concerning species abundances and metabolite concentrations. Here we apply a model-based approach to integrate such experimental data and thereby infer metabolic-exchange fluxes. We designed a synthetic anaerobic co-culture of Clostridium acetobutylicum ...
Thermochemical treatment was investigated experimentally at different air fluxes in an updraft reactor. The test rig equipped with a special attached door that will open specific time step. This unique feature allows investigators to obtain information on the packed bed color variation along heights of reactor evolves points time. analysis focused temperature dynamics obtained from installed th...
