  Flux - Wikipedia, the free encyclopedia
The movement of molecules across a membrane: in this case, flux is defined by the rate of diffusion or transport of a substance across a permeable membrane.
Except in the case of active transport, net flux is directly proportional to the concentration difference across the membrane, the surface area of the membrane, and the membrane permeability constant.
In [ecology]], flux is often considered at the ecosystem level - for instance, accurate determination of carbon fluxes (at a regional and global level) is essential for modelling the causes and consequences of global warming.

In biology, flux refers to the movement of molecules across a membrane: the rate of diffusion of a substance across a permeable membrane.
Net flux is directly proportional to the concentration difference across the membrane, the surface_area of the membrane, and the membrane permeability constant.
For electromagnetic_radiation, the flux of the Poynting_vector through a surface is the power, or energy per unit time, passing through that surface.

The annual net flux estimates by region for the period 1850 to 1990 were graphed and visually compared with Figure 5 in Houghton (1999), and the annual global total estimates for the period 1850 to 1990 were graphed and visually compared with Figure 6 in Houghton (1999).
The global total net flux estimates, derived from this database, for the periods 1850 to 1980 (103 Pg of carbon) and 1850 to 1990 (124 Pg of carbon) were compared with the corresponding totals reported in Table 3 of Houghton (1999).

The null flux guideway loop is wound so that when the vehicle is at the symmetry point of the loop, the net magnetic flux through the loop circuit is zero.
When the superconducting (SC) loop on the vehicle is exactly halfway between the upper and lower halves of the null flux guideway loop circuit, the net flux through the circuit is zero, because the top half loop is wound in the opposite direction from the bottom half loop.
The same null flux principle applies to the "Figure of 8 loop." When the vehicle SC loop is centered on the "Figure of 8 loop," the net magnetic flux through the "Figure of 8" loop circuit is zero.

 Strategies for Measuring and Modelling Net Ecosystem CO2 Flux from   (Site not responding. Last check: 2007-11-07)
Long-term measurements of CO net exchange and NEP by eddy-covariance (Goulden et al., 1996 a,b) have shown interannual changes in net uptake by midlatitude deciduous forests analogous to anomalies in the global atmospheric accumulation rate (Keeling et al., 1996), with increased rates of annual uptake associated somewhat unexpectedly with positive temperature anomalies.
The time duration of flux measurements must be sufficient to observe the various time scales that are associated with the processes that control the fluxes of carbon dioxide and water vapor into and out of the systems.
Measurements of appropriate flux, climate, soil and biological parameters must be made therefore on time scales from hours to years, with meticulous attention to the procedures for data aggregation to avoid accumulation of error.

 Map - Net Flux of Carbon to the Atmosphere from Land-Use Change, 2000
Positive values indicate a positive net flux ("source") of CO2; for these countries, carbon dioxide has been released into the atmosphere as a result of land-use change.
Negative values indicate a negative net flux ("sink") of CO2; in these countries, carbon has been absorbed as a result of the re-growth of previously removed vegetation.
Houghton states that yearly flux estimates are uncertain on the order of ±150% for large fluxes, and ±50 MtC/yr for estimates near zero.

The net flux, background, ripple, and noise spectra are in units of FN, the flag spectrum is in bit-encoded unitless values, and the calibrated flux spectrum is in physical units of ergs sec
The net flux and noise spectra are computed over the entire wavelength space of the high-dispersion SI, but locations that are outside the camera target area will have net fluxes equal to zero because these regions do not contain any valid image data.
The valid wavelength limits of the calibrated spectra are consequently somewhat truncated as compared to the net flux spectrum.

Always keep in mind, that the xch values are for the rescaled [0,1] scale, so the xch flux of ppp3 is de facto not measureable by the chosen label measurements.
On the other hand the flux ppp2 is determined very well, having deviations of net: 0.0179471 and xch: 0.0525003.

 Chapter 9: The Effect of Catalysed and Uncatalysed Enhancement on the Net Global Air-Sea CO2 Flux.
The net global air-sea CO flux is finely balanced and dependent on the intercorrelation between the various parameters, as shown by the preliminary calculations already presented in Section 3.3.
The CO flux due to chemical enhancement is a small fraction of the total net global air-sea CO flux, which is itself a small fraction of the gross regional and seasonal air-sea and sea-air CO fluxes (see Section 1.3).
From the flux maps it is clear that in August much of the north Atlantic is a source of CO to the atmosphere, but north of a line between Ireland and Newfoundland it is a sink, and this sink may be enhanced by a high concentration of enzyme.

 E3. Gauss's Law   (Site not responding. Last check: 2007-11-07)
The net charge enclosed by the ellipsoid is +Q - Q = 0.
In fact this is the case: the net charge of the distribution is zero, so (almost) every field line beginning on the +Q must end on the -Q. (We can ignore the two exceptional fieldlines on the axis, because a single fieldline in itself doesn’t cover any finite area on the ellipsoidal surface.)
But even if we did not realize that (almost) every field line leaving the surface eventually re-enters, we could still see that the net flux passing outward is zero.
