Evolution of crop yields and qualities in a short rotation coppice alley croppi...
Jung, L.; Barwolff, M.; Vetter, A.Poster ; A modern form of agroforestry are alley cropping systems where annual field crops are grown in combination with strips of fast-growing tree species, so-called short rotation coppices (SRCs). Besides fulfilling the farmers requirements to keep the field in the state of production, SRC strips provide many of the well-known positive functions of hedges. They act as wind shelter, reducing soil erosion. By...
Short rotation coppices along watercourses - an innovative combination of susta...
Furstenau, C.; Vetter, A.Poster ; The multiple advantages of short rotation coppices (SRC) such as sustainable energy wood production, income diversification, and ecological services are well known and investigated in various projects. Additionally, strips of SRC present an innovative instrument to buffer nutrient and pesticide contamination of watercourses induced by soil erosion. Through extensive management, provision of permanent ...
Non-Fluorinated Membranes Thickness Effect on the DMFC Performance
Vasco Freitas Silva; Valter B. Silva; R. Reissner; S. Vetter; A. Mendes; L. M. Madeira; S. P. NunesIn order to study the influence of the proton exchange membrane thickness on the direct methanol fuel cell (DMFC) performance, sulfortated poly (ether ether ketone) (sPEEK) membranes with a sulfonation degree (SD) of 42% and thicknesses of 25, 40, and 55 pm were prepared, characterized, and tested in a DMFC. These polymeric membranes were tested in a DMFC at several temperatures by evaluating the current-voltag...
