Background: Natural organic matters (NOMs) have the main role in formation of trihalomethanes. These compounds are in natural water sources due to biological activities. In the presented study, adsorption and separation of humic acid as an index of natural organic matters using multi-walled carbon nanotubes is evaluated. Methods: The experiments were carried out in bath adsorption reactors wit...

This paper assesses the impact of French policies for residential space-heating energy consumption, both enacted (tax credits for the purchase of energy efficient durables, soft loans for retrofitting actions, stringent building codes) and anticipated (carbon tax, retrofitting obligation). It uses a hybrid energy-economy model incorporating specific features of energy conservation, notably the ...

E to green the building industry are strongly linked to performance metrics such as Leadership in Energy and Environmental Design (LEED). Yet, despite the importance of climate impact as a driver of green building choices, such standards typically address a basket of poorly quantified “green” attributes and, when they do address energy, they focus on conservation rather than carbon emissions so...

Forest ecosystems are among the largest terrestrial carbon reservoirs on our planet earth thus playing a vital role in global carbon cycle. Presently, remote sensing techniques provide proper estimates of forest biomass and quantify carbon stocks. The present study has explored Landsat-8 sensor product and evaluated its application in biomass mapping and estimation. The specific objectives were...
