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.
The deposition of Hg from the atmosphere to Earth surfaces and its re-emission
via biogeochemical reduction processes determine Hg concentrations in Earth surface reservoirs, such as soils, snow, and runoff into Arctic lakes and surface Ocean.
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
of nicotine from contaminated indoor surfaces in these households can lead to nicotine exposure levels similar to that of smoking.
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.
efficiency is highly dependent on the wavelength of the blue flux.
o], efficiency of absorption and re-emission

of sorbed VOCs can dramatically elevate VOC concentrations in the indoor environment for months or years after a source event (Nielsen 1987; Tichenor et al.
