We present a systematic comparison of tropospheric NO2 from 17 global atmospheric chemistry models with three state-of-the-art retrievals from the Global Ozone Monitoring Experiment (GOME) for the year 2000. The models used constant anthropogenic emissions ...
This report provides a short introduction to process principles, feedstock and technology for the most important biomass and waste biomass conversion routes. ...
In the order to produce energy for the large amount of people still currently out of the national girds, different possibilities exist. For practical and economic reasons, the most popular one is the use of Diesel engines coupled with generator sets. Petro ...
Short-term field experiments are often used to predict and evaluate long-term management effects. Based on a mowing experiment in two calcareous fens near Lake Neuchatel, Switzerland, we investigated whether shea-term treatment effects (i.e. during the fir ...
Optimal Operation of Batch Processes with Multiple Inputs and Constraints B. Srinivasan, S. Palanki, and D. Bonvin Optimal operation of batch processes has become increasingly important in recent years in the face of increased competition and also due to t ...
The downfield chem. shifts of arene hydrogens (delta 1H) are due only in part to the pi ring current contribution [sigma.dblvert.(pi)]; local framework effects are equally important. Neither proton chem. shifts nor even sigma.dblvert.(pi) tensor elements, ...
Results on solid oxide fuel cell stacks tested at 800° C with H2 fuel and using planar Ni-zirconia anode supported cells, 80x80x0.2 mm in size, are presented. Modeling and numerical simulation is used to interpret observed results and develop improved desi ...
Failure detection and group membership are two important components of fault-tolerant distributed systems. Understanding their role is essential when developing efficient solutions, not only in failure-free runs, but also in runs in which processes do cras ...
We present a 650-year Antarctic ice core record of concentration and isotopic ratios (δ13C and δ18O) of atmospheric carbon monoxide. Concentrations decreased by ∼25% (14 parts per billion by volume) from the mid-1300s to the 1600s then recovered completely ...

Biomass burning is a major source of atmospheric brown carbon (BrC), and through its absorption of UV/VIS radiation, it can play an important role in the planetary radiative balance and atmospheric photochemistry. The considerable uncertainty of BrC impact ...
