6. Year-round production of forest seedlings under LED lamps : Biological and energetic implications of indoor cultivation
Sammanfattning : Year-round cultivation of forest seedlings under light emitting diodes (LED) is a technology receiving increased attention from nurseries in the boreal forest regions. In these areas, the climate is characterized by strong seasonal fluctuations, resulting in short vegetation periods with narrow time windows for seedling transplanting and outdoor growth. LÄS MER
7. Litteraturens uppodling : Läsesällskap och litteraturkritik som politisk strategi kring sekelskiftet 1800
Sammanfattning : The aim of the dissertation is to study the distribution of literature as a means to disseminate knowledge in the context of two reading societies and three critical journals based in Uppsala and Åbo. This dissemination, regarded as a strategy towards social and political reform, took place in these societies and journals, which were geographically, biographically, intentionally and functionally connected.

8. A study of ethylene production via the 2-oxoglutarate dependent pathway in S. cerevisiae
Sammanfattning : The detrimental effect of the petroleum industry on the environment combined with the threat of peak oil has driven the exploration for alternative strategies to produce traditional petrochemicals. Biotechnological production could be an alternative, using microorganisms to convert renewable feedstocks into desired products. LÄS MER
9. Volatile metabolites from microorganisms in indoor environments : sampling, analysis and identification
Sammanfattning : Microorganisms are able to produce a wide variety of volatile organic compounds. This thesis deals with sampling, analysis and identification of such compounds, produced by microorganisms commonly found in buildings. LÄS MER
10. Engineering synthetic pathways for adipic acid biosynthesis
Sammanfattning : Utilization of petroleum in consumer product manufacturing is causing irreversible environmental damage. Its impact on land, sea, and air calls for the development of more sustainable technologies based on the use of renewable materials such as lignocellulosic biomass and its conversion into platform chemicals.
