Thin films of crystalline mesoporous cerium dioxide were prepared by using a template of a copolymer surfactant (Pluronics 123) at ambient conditions in ethanol. The synthesised ceria was produced via a direct calcination step, without using a gelling stage. The precipitated CeO₂ matrix was crystalline with a high surface area. The solution height over the synthesis vessel before the ca

This dissertation has three cornerstones: * Haptics * Human-Computer Interaction (HCI) * Blind Users Haptics deals with controlling human movements and getting feedback through the sense of touch. A haptic interface transmits forces to a person’s hand or fingers in a way that mimics the sensation of touching real objects. Virtual haptic touch can be particularly useful for people with visual i

Mobility Management (MM) syftar till att främja hållbara transporter och minska resandet med bil genom att förändra resenärers attityder och beteenden. Denna rapport är framförallt ett underlag inför framtida satsningar på MM-åtgärder i Lund och Helsingborg. Detta är ingen före-efter analys då det i nuläget inte finns material för att göra en sådan studie. Istället kan rapporten användas för en fr

Popular Abstract in Swedish Den enorma variationen av beteenden och utseenden som återfinns i djurriket har i alla år fascinerat och länge förbryllat biologer. Rovdjurens skoningslösa utgallring är en av de stora drivkrafterna bakom evolutionen av alla dessa karaktärsdrag. Rovdjuren är såklart även en viktig strukturerande kraft i sötvattensmiljöer och har där lett till utvecklingen av mängder av The varieties of prey phenotypes that have been revealed in nature are vast and many of these phenotypes are the result of the selective force that predators have had on prey traits in the past. Even within species and populations we see variations due to both differences in the selection forces they live under but also due to individual trait variation. In this thesis I investigate both the direc

In Rabinowicz & Rønnow-Rasmussen (1999), we defended the following claims: (i) Not only states of affairs, or facts, but also concrete objects, such as things or persons, may have final value (value for their own sake); (ii) The final value of a concrete object need not be intrinsic, i.e., it need not be exclusively based on the internal (non-relational) properties of its bearer; (iii) The fi

This thesis concerns a novel alkaline protease produced by an extremophilic microbial specie, designated as AL20, isolated from a feather sample collected at the shore of the alkaline soda lake Abjata in the Ethiopian Rift Valley. The isolate is a heterotrophic, alkaliphilic, halotolerant gram-positive, strictly aerobic, non-motile, non-spore forming bacterium. The organism grew at 37°C, pH 10, an

Today’s cloud data center infrastructures are not even near being able to cope with the enormous and rapidly varying capacity demands that will be reality in a near future. So far, very little is understood about how to transform today’s data centers (being large, power-hungry facilities, and operated through heroic efforts by numerous administrators) into a self-managed, dynamic, and dependable i
