Neue Wege bei der stofflichen Verwertung von expandiertem Maisschrot
(2024-08-20)The dissertation deals with a material based on expanded corn grits. In three work packages, various methods for adapting or improving the properties of this material are presented and discussed. The first work ... -
MDF Recycling: Recovering fibres from fibreboards for further material utilisation with a focus on the chemical and morphological alteration of the recovered fibres
(2023-02-01)The present research was performed within the scopes of the DFG Research Training Group 1703 “Resource Efficiency in Interorganizational Networks” and AiF Project GmbH (project No. 16KN065229), which aims at developing a ... -
Herstellung von Holzfaserdämmstoffen auf Laub- und Nadelholzbasis mit dem Fokus auf der Fasercharakterisierung, sowie der Ermittlung der physikalischen, mechanischen und biologischen Eigenschaften
(2022-10-19)The objective of this work was to investigate the use of hardwood fibres for the production of wood fibre insulation materials in order to provide a broader range of raw materials against the background of ecological forest ... -
Entwicklung von leichten, dreischichtigen Sandwichverbundplatten unter Verwendung des Agrarrohstoffes Mais
(2016-09-20)The development of wood composites such as fibreboards or particle boards rely on the intention to improve the efficiency of the wood use and to expand the application of the material wood. The conventional wood composites ... -
Treatment of solid wood with silanes, polydimethylsiloxanes and silica sols
(2014-11-25)The study can be divided into three sections. In the first section, wood was treated with different commercially available silica sols of varying pH and surface modification. While alkaline silica sols could not be impregnated ... -
Insect olfaction as an information filter for chemo-analytical applications
(2014-04-17)The olfaction of insect species is adapted to the requirements of the specific ecosystem they are living in. Volatiles perceived by insects can transport information on the location of an oviposition place or the physiological ... -
Odour signals relevant to beetles in deadwood habitats - odorants, olfaction and behaviour.
(2012-09-26)The overall objective of this work was to evaluate and determine volatile chemical cues (infochemicals) that determine insect-wood interactions. The deadwood habitat comprises species that reproduce and spend obligatory ... -
Genetic processes in Scots pine (Pinus sylvestris L.) in the Chernobyl exclusion zone
(2011-02-18)As immobile organisms, plants have to tolerate unfavorable environmental conditions and make use of different adaptive mechanisms to survive and reproduce successfully under stress. It is ... -
Isolierung von DNA aus rohem und bearbeitetem Holz von Dipterocarpaceen
(2010-12-03)Forest destruction and degradation (deforestation) remain major threats to the global biodiversity and cause enormous environmental damage in particular in tropical regions, where the highest ... -
Laccases and other ligninolytic enzymes of the basidiomycetes Coprinopsis cinerea and Pleurotus ostreatus
(2009-12-23)Organisms produce ligninolytic enzymes in order to degrade lignocellulosic materials. Mainly, such enzymes are found in the fungal kingdom and are particularly widespread in the phylum ... -
Development of a Basic Biosensor System for Wood Degradation using Volatile Organic Compounds
(2009-05-27)Wood inspection and durability testing of wood against microorganisms, as fungi, play an important role in forestry and wood-related material industries. An efficient testing method is ... -
Hydrophobins in wood biology and biotechnology
(2009-03-25)The main aims of this research were to study the role of hydrophobins in wood decay processes and to test the ability of these proteins to coat surfaces, particularly wood surfaces. ... -
Technological Investigation of Prosopis leavigata Wood from Northeast Mexico
(2007-10-10)This study describes the anatomical properties of Prosopis laevigata trees found in northeast Mexico. The chemical composition and the topochemical distribution of lignin and phenolic ... -
The Distribution of the Genetic Diversity in <i>Araucaria angustifolia</i> (Bert.) O. Kuntze populations and its implications for the conservation of the species
(2007-10-02)Genetic markers have been widely used for the assessment of levels of genetic diversity in various species, for the determination of their conservation status and for the derivation of ... -
Development of microsatellites in Prosopis spp. and their application to study the reproduction system
(2007-09-19)Prosopis chilensis and Prosopis flexuosa, two hardwood arboreal species, constitute important natural resources. They play a vital role in the ecology and the economy of arid and ... -
Extracellular proteins from lignocellulose degrading Basidiomycetes: Redox enzymes from Trametes versicolor and Coprinopsis cinerea
(2007-02-05)The extracellular proteome of fungi consists of three different fractions: proteins secreted freely into the medium, the hyphal sheath proteins, and cell wall-associated proteins. Methods for isolation and characterization ... -
Genetic variation of the genus <i>Shorea</i> (Dipterocarpaceae) in Indonesia
(2006-03-27)This dissertation is composed of three parts using the AFLP marker technique to characterize genetic variation of Indonesian dipterocarps, a dominant tree family in Asian tropical rainforests: ...
