abstract = {In dem, im Artikel beschriebenen Projekt sollen Bodend\"{a}mmplatten entwickelt werden, die sowohl eine geringe W\"{a}rmeleitf\"{a}higkeit als auch eine hohe mechanische Belastbarkeit aufweisen. Basis der Bodend\"{a}mmplatten sind Getreidespelzen, die in gro\ssen Mengen als Nebenprodukt in der Lebensmittelproduktion anfallen und nur vereinzelt weiterverwendet werden k\"{o}nnen. Die Entwicklung der D\"{a}mmplatten (siehe Abb.1 und 2) erfolgt in Zusammenarbeit mit der Holz-Lehmhaus GmbH. An die Bodend\"{a}mmplatten werden folgende Anforderungen gestellt:



 



-       geringe W\"{a}rmeleitf\"{a}higkeit (gute W\"{a}rmed\"{a}mmung)



-       hohe mechanische Belastbarkeit



-       Brandschutz (schwer entflammbar, B1 nach DIN 4102)



-       hohe Feuchtigkeitsbest\"{a}ndigkeit / geringes Aufquellen bei Kontakt mit Wasser



 

Um eine m\"{o}glichst geringe W\"{a}rmeleitf\"{a}higkeit zu erreichen, wird zun\"{a}chst ein mathematisches Modell der D\"{a}mmplatte erstellt. Auf Basis des theoretischen Modells k\"{o}nnen variable Parameter wie zum Beispiel Spelzengr\"{o}\sse und -dicke angepasst und hinsichtlich der thermodynamischen Eigenschaften und damit der W\"{a}rmeleitf\"{a}higkeit optimiert werden.},

abstract = {Winter catch crops are grown to scavenge nutrients over a period of unfavorable growth conditions and to conserve nutrients for subsequent release to the following main crop. Since environmental conditions have a strong impact on the growth and nutrient capture in roots and shoots of individual catch crop species, we anticipated that mixtures will be more durable and efficient in nutrient capture due to compensatory effects among component species. We tested this hypothesis and determined the nitrogen and phosphorus accumulation in the shoots and roots of four catch crop species grown in pure vs. mixed stands at two sites for two or three years. Element concentrations were determined in the root and shoot biomass of each species and used to calculate the nutrient pool fixed in the root or shoot biomass. A qPCR-based technique was applied to quantify the root biomass of individual species based on species-specific DNA sequences. Despite considerable variation across environments, the overall plant biomass of white mustard (Sinapis alba), lacy phacelia (Phacelia tanacetifolia) and bristle oat (Avena strigosa) was similar and higher than that of Egyptian clover (Trifolium alexandrinum). While pure stands varied 6- to 24-fold in shoot biomass depending on environmental conditions, the variation was only ~3-fold for catch crop mixtures, with less pronounced variation in the root biomass. In general, the root biomass was comparable to the shoot biomass in each species. Roots contributed 26\textendash46% of the nitrogen and 36\textendash48% of the phosphorus to the total accumulation of these nutrients in the catch crop biomass, thus emphasizing the importance of plant roots as belowground nutrient pool for potential carry-over of nutrients to the subsequent crop. Although the mixture was mostly dominated by two of the four species, namely mustard and phacelia, it captured similar or even larger amounts of nutrients than the best-performing pure stand under any growth condition. This was the case for shoot- and for root-bound nutrients. Our results indicate that catch crop mixtures have higher durability than pure cultures to environmental variations. The amount of nitrogen captured by the mixture meets the average postharvest nitrogen that is left over by a wide range of cash crops, thus emphasizing that catch crop mixtures represent an efficient nutrient management tool in crop rotations.},

abstract = {While the main objective in energy production is the reduction of fossil fuels, CO2-production by fossil fuels increased over the last decade. Therefore the need for usage of regenerative energies is obvious. Biogas plants are advantageous because they can be used with-out spatial limitation and their substrate is abundant ubiquitously as it covers the whole range of produced organic matter from photosynthesis, municipal, industri-al and animal waste. Although the need for optimization strategies is given, the fermentation process in biogas plants is complex and therefore traditional optimization approaches are cumbersome and carry the risk of com-plete plant failure. In this paper the optimization poten-tial of the ADM1, which represents a detailed description of the anaerobic digestion process is analysed and com-pared to the standard ADM1 setup. Technical parame-ters like substrate composition and dilution rate are optimized to yield a high methane gas flow. It is shown that the optimization of substrate composition has a direct impact on the maximum applicable dilution rate. It is also shown that the feeding rate can be increased to yield higher productivities with optimized substrate compositions.},
