Within nuclear reactors, neutrons are a primary product of nuclear fission. By controlling the rate of the nuclear reactions, one controls the flux of neutrons and provides a steady supply of neutrons. For a diffraction analysis, a narrow band if neutron wavelengths is selected (fixing X) and the angle 20 is varied to scan the range of values. 

In the presence of a magnetic flux, the boundary condition is changed hy the Aharonov-Bohm effect and the band gap exhibits an oscillation between 0 and 2nylL with period 0q is shown in Fig. 3. 

Fig. 5. Energy bands of a metallic CNT in the presence of a magnetic flux and allowed optical transitions for the x and y polarisations.

In the optical absorption, two different polarisations of light should be considered the electric field is along (parallel or y polarisation) and perpendicular (perpendicular or x) to the axis. Figure 5 shows the energy band of a metallic CNT for flux < )/< )o =0, 1/4 and 1/2 and the process of optical transitions for the parallel and perpendicular polarisations. Some examples of calculated absorption...

Research is needed to quantify and assess data sets on pools and fluxes of subfossil carbon for North America, Scandinavia, and the Soviet Union where large amounts of such material exists and is vulnerable to accelerated decomposition with expected C02-induced climate change 66-69). Billings et al. 70, 71) performed fleld experiments that mimicked the changes expected to occur in the tundra as a result of climatic change. The direction of CO2 flux was reversed from a net storage of 150 g C02 m -season to a net release of 300-400 g C02 m" season . Annual liberation of as little as 1% per year of either the 300 Pg C stored in the top meter of soils above the 60° latitude band or... 

Figure 5. An example of the use of concentrations to assess changes in sediment mass accumulation taken from McManus et al. (1998). The upper panel shows the measured °Thxs, calculated from measured °Th concentrations by correction for detrital °Th, and for the effects of age using 5 0 stratigraphy (see Appendix). Because the supply of °Th to the sediment is a constant, low °Th represent times of rapid sediment mass accumulation. The calculated mass flux is shown in the lower panel. Dramatic increases in mass flux are observed during all but one of the Heinrich events, shown by the gray bands.
