1. An exploration of freshwater microbial ecology : from streamlined genera to global networks
Sammanfattning : Microbes are the main drivers of biogeochemical cycles on Earth and even though freshwaters cover only a small area of terrestrial surfaces their contribution to global cycles is important. Global cycles are measured by exchanges between systems e.g. water to atmosphere or lithosphere and are mediated by microbial communities. LÄS MER
2. Evolution of streamlined genomes in ultra-small aquatic bacteria
Sammanfattning : This thesis investigates the evolutionary processes of streamlined genomes from aquatic bacteria adapting to different salinities, using two groups of ultra-small aquatic bacteria (LD12 Alphaproteobacteria and acI Actinobacteria). Due to difficulties in obtaining pure cultures of these bacteria, culture-free approaches (single-cell genomics and metagenomics) were used to construct and compare genomes, and to study the mechanisms and selective forces of adaptation to freshwater, brackish, and marine ecosystems.

3. The drumlin problem : streamlined subglacial bedforms in southern Sweden
Sammanfattning : This thesis investigates stream-lined subglacial bedforms (often referred to as drumlins) in southern Sweden. The broad aim of this is to contribute to the solution of the ‘drumlin problem’. The term drumlin has come to be applied to a wide range of features whose internal architecture (core) and overall morphology are seen to vary greatly. LÄS MER
4. Environmental, health, and safety assessment of chemical alternatives during early process design: The role of predictive modeling and streamlined techniques
Sammanfattning : Industrial chemicals are important for many aspects of modern life, though they can be harmful to the environment and human health. Environmental or safety concerns identified during the early design and selection of chemicals could motivate choices as to safer alternatives and process setups. LÄS MER
5. Deglaciation pattern and dynamics in the Bolmen area, southwestern Sweden
Sammanfattning : The Late Weichselian deglaciation of an area in southwestern Sweden was reconstructed by geomorphological, sedimentological and lithostratigraphical methods. The morainic deposits were mapped and classified into three landsystems: Streamlined terrain, hummocky moraine and cover moraine. LÄS MER
