6. Natural Products from Cameroonian Medicinal Plants
Sammanfattning : Natural product chemistry is a main research area in Cameroon, as well as for the division of Bioorganic Chemistry at Lund Institute of Technology. A review of the results obtained recently with Cameroonian medicinal plants shows that a large number of compounds, many with complex structures, have been isolated and characterised, and the work presented in this thesis is part of this effort.

7. Buildability of concrete structures : processes, methods and material
Sammanfattning : The causes for the slow development of the construction industry is often attributed the traditional ”peculiarities of construction“, including such factors as one-of-a-kind products, temporary organisation, and on-site production. However, signs of new thinking are becoming apparent in the construction industry in Sweden that emphasise change. LÄS MER
8. Xyloglucan-active enzymes : properties, structures and applications
Sammanfattning : Cellulosabaserade material är världens rikligast förekommande förnyelsebara råvara. Växters cellväggar är naturliga kompositmaterial där den kristallina cellulosan är inbäddad i en väv av hemicellulosa, strukturproteiner och lignin. LÄS MER
9. Strengthening of timber structures with flax fibres
Sammanfattning : The natural defects present in timber are the source of large variations in mechanical properties. This drawback has been partially counteracted with the use of Engineered Wood Products EWP (glulam, composite I-beam, parallel strand lumber, etc.) instead of solid wood. LÄS MER
10. Natural corrosion in reinforced concrete structures
Sammanfattning : Among the threats to the durability of concrete structures, corrosion of the reinforcement bars is undoubtedly the most common one. Corrosion damages impair safety and durability of infrastructure, and assessment of the safety is challenging due to the complex nature of the corrosion process. LÄS MER
