1. Samtal om begreppskartor : en väg till ökad förståelse
Sammanfattning : Denna avhandling belyser hur elevdiskussioner om begreppskartor kan bidra till en ökad förståelse för innebörden av de utvalda biologiska begreppen hos de elever som deltar. Som bakgrund till avhandlingen redovisas forskningsresultat vilka visar ett antal svårigheter elever kan ha inom det cellbiologiska ämnesområdet. LÄS MER
2. Implementering av lärande för hållbar utveckling : En studie av rektors förståelse av kvalitet i skolans organisation
Sammanfattning : Student outcomes of Education for Sustainable Development (ESD) is reported to be weak and empirical studies investigating the underlying causes have been called for. School organization is pointed out as essential, which highlights the role of school leaders in realizing ESD. LÄS MER
3. Sequence- and structure guided engineering of proteins and enzymes for biotechnology and health applications
Sammanfattning : Proteins are highly diverse and sophisticated biomolecules that represent a cornerstone of biological structure and function and have been exploited in man-made applications for thousands of years. Those proteins that facilitate chemical reactions at physiologically relevant time-scales are referred to as enzymes. LÄS MER
4. Perturbance and Stimulation : using Nitrogen Addition and High-Throughput Sequencing to Study Fungal Communities in Boreal Forests
Sammanfattning : Fungal communities are major players in globally important nutrient cycling processes, and form symbioses with most terrestrial plants. In the nitrogen (N) limited Swedish boreal forest, ectomycorrhizal (EcM) fungi colonize most roots of the economically important and stand dominating conifer species, Norway spruce (Picea abies) and Scots pine (Pinus sylvestris), with significant implications for tree nutrition and decomposition processes.

5. Nucleic Acids as Drug Targets - Influence of Platinum Complexes on Duplex Stability and Binding Kinetics
Sammanfattning : Gaining a detailed understanding of how human cells are affected by metal-based drugs is crucial, since these drugs have shown great potential in cancer treatment. Cisplatin is used to treat many different types of cancer, e.g. testicular, ovarian, melanoma, bladder, non-small cell lung cancer, small cell lung cancer, myelomas and lymphomas. LÄS MER
