This study compares six wastewater sludge treatment scenarios applied to a 300,000 equivalent-inhabitant (eq. inh) wastewater treatment plant: agricultural spreading, fluidised bed incineration, wet oxidation, pyrolysis, incineration in cement kilns and la ...
This study addresses two major challenges in the field of climate change impact analysis on water resources systems: i) incorporation of the largest possible range of potential climate change scenarios and ii) quantification of related modelling uncertaint ...
Tropospheric ozone (O3) is a key component of air pollution and an important anthropogenic greenhouse gas1. During the twentieth century, the proliferation of the internal combustion engine, rapid industrialization and land-use change led to a global-scale ...
Anthropogenic increases in atmospheric carbon dioxide (CO2) concentrations may affect vegetation distribution both directly through changes in photosynthesis and water-use efficiency, and indirectly through CO2-induced climate change. Using an equilibrium ...
All recent climatic projections for the next century suggest that we are heading towards a warmer climate than today (Intergovernmental Panel on Climate Change; Fifth Assessment Report), driven by increasing atmospheric burdens of anthropogenic greenhouse ...
We present a systematic study of the oscillator strength of the positively charged excitons (X+) in Cd1-xMnxTe quantum wells. CW-absorption and time-resolved photoluminescence measurements were combined as two approaches for the determination of the oscill ...
The present work analyzes the climate change impacts on the runoff regimes of mountainous catchments in the Swiss Alps having current glaciation rates between 0 and 50 %. The hydrological response of 11 catchments to a given climate scenario is simulated t ...
An atmospheric transport model and observations of atmospheric CO2 are used to evaluate the performance of four Terrestrial Carbon Models (TCMs) in simulating the seasonal dynamics and interannual variability of atmospheric CO2 between 1980 and 1991. The T ...
The time dependence of the photoluminescence of GaN/AlN quantum dots (QD's) after high photoexcitation is examined on a large time scale. A continuous change in energy peak is reported, resulting in a giant energy shift of more than 1 eV after delays of se ...
We have studied experimentally the radiative lifetimes of negatively charged excitons (X-) and neutral excitons (X) in GaAs and CdTe quantum wells. Despite the different optical properties (e.g. trion binding energies) and the different quantum well struct ...
