1. Stabilization of fine-grained soils in cold environment and exposed to seasonal frost : By-products as hydraulic binders
Sammanfattning : This doctoral thesis deals with the stabilization of ﬁne-grained soils using by-product originated hydraulic binders. The use of ﬁne-grained soils as subsoil for infrastructure projects is often limited because of the risk for instability. LÄS MER
Sammanfattning : This thesis consists of four papers on the topics of free loop spaces, Koszul duality and A∞-algebras. In Paper I we consider a definition of differential operators for noncommutative algebras. This definition is inspired by the connections between differential operators of commutative algebras, L∞-algebras and BV-algebras. LÄS MER
Sammanfattning : The solar energy accumulated by photosynthesis over billions of years is the sole source of energy available on Earth. Photosystem II (PSII) uses the sunlight to split water, an energetically unfavorable reaction where electrons and protons are extracted from water and oxygen is released as a by-product. LÄS MER
Sammanfattning : The work presented in this thesis has been aiming at improving ethanol production from lignocellulose. Ethanol from renewable resources is receiving renewed attention due to apprehensions of global warming and dwindling oil reserves. Lignocellulose constitutes a potential raw material source for large scale ethanol production. LÄS MER
Sammanfattning : A series of new dioxomolybdenum(VI) and -tungsten(VI) complexes of tripodal tetradentate and tridentate amino bis- and monophenolate ligands have been synthesized and characterized. The majority of the complexes are mononuclear, but dimeric and trimeric oxo-bridged M(VI) (M = Mo, W) were also obtained. LÄS MER
