1. Influence of water conditions on growth and mineral nutrient uptake of native plants on clacareous soil
Sammanfattning : The studies presented in Papers I to IV illustrate the importance of soil moisture in soil solution chemistry and response of native plants to the changes induced by change in moisture regime. With the help of glasshouse experiments I tried to study the influence of different treatments of soil moisture conditions on the mineral uptake by native plants of calcareous soil. LÄS MER
2. Transient vibrations from dry clutch operation in heavy-duty truck powertrains : Modelling, simulation and validation
Sammanfattning : For internal combustion engines used in heavy-duty vehicles, increased engine efficiency and consequently reduced CO2 emissions can be obtained if the engine speed can be kept within an optimal speed range. This requires swift and frequent gear shifts where the dry friction clutch is utilized. LÄS MER
3. Treatment of Wastewater Generated by Wood-based Dry Industries : Advances Oxidation Processes & Electrocoagulation
Sammanfattning : Wood is a material with an enormous number of applications. For decades, the development of wastewater treatment technologies tailored for the wood sector has focused on those industries that have water as an integral part of the industrial production, such as paper and pulp.

4. Two-Stage Conversion of Land and Marine Biomass for Biogas and Biohydrogen Production
Sammanfattning : The replacement of fossil fuels by renewable fuels such as biogas and biohydrogen will require efficient and economically competitive process technologies together with new kinds of biomass. A two-stage system for biogas production has several advantages over the widely used one-stage continuous stirred tank reactor (CSTR). LÄS MER
5. Bioprocessing of Recalcitrant Substrates for Biogas Production
Sammanfattning : The application of anaerobic digestion (AD) as a sustainable waste management technology is growing worldwide, due to high energy prices as well as increasingly strict environmental regulations. The growth of the AD industry necessitates exploring new substrates for their utilisation in AD processes. LÄS MER
