Depending on the form and dynamism of such a taxation system, presuming it manages to cover also the materials used for construction works and their final impact on the surroundings such as their effect of heat accumulation and re-emission
to the ambient, research of advanced materials with limited impact on the environment could be encouraged within the private sector.
"Galaxies forming stars in the distant universe seem to be surrounded by an impressively large, faint halo of Lyman-alpha photons that had to travel for hundreds of thousands of light years in an almost endless series of absorption and re-emission
events, until they were finally free.
While available standards address important aspects of indoor pollutant removal performance, (5-8) none deal with other specific performance issues for indoor applications such as: harmful by-product formation to protect human health; re-emission
of captured VOC; and IPPT testing in chambers that can simulate air velocity and turbulence levels typically found in indoor environments, (9) as well as simulate visible light illumination using a conventional indoor lighting source (instead of a UV source).
Here we present experimental evidence for protracted photon storage and markedly delayed re-emission
within malignant cell cultures.
The only reasonable mechanism available, in the context of a gaseous Sun, involves direct excitation through photon absorption and subsequent re-emission
. Thus, a random process is invoked.
of nicotine from contaminated indoor surfaces in these households can lead to nicotine exposure levels similar to that of smoking.
Xu, "Enhanced [Hg.sup.2+] removal and [Hg.sup.0] re-emission
control from wet fuel gas desulfurization liquors with additives," Fuel, vol.
* Specify isolation requirements (isolation of porous materials to avoid adsorption and subsequent re-emission
of solvents; maintaining negative ventilation in construction areas).
In addition to band edge emission at 447 and 375 nm, related to as grown film at sputtering power of 60 and 80 W, respectively; there are two re-emission
mechanisms for Ti:[Cu.sub.3]N films; first, as discussed in, (16) interstitial nitrogen excess acts as electron acceptor centers.
efficiency is highly dependent on the wavelength of the blue flux.
These elements are; mass ratio of the system q, fractional radius of the optical component r, limb darkening coefficient u, gravity darkening coefficient [t.sub.o], efficiency of absorption and re-emission
h, optical X-ray luminosity ratio [L.sub.opt]/[L.sub.x] and the effective temperature of the optical star [T.sub.eff].
