Det är svårt att tänka sig dagens samhälle utan katalys då många av de produkter som vi använder dagligen framställs med någon form av katalysator med tillämpningar som sträcker sig från kemikalieproduktion till avgasrening. Den mest kända katalysatorn är nog bilkatalysatorn som används för att omvandla de mest skadliga bilavgaserna till mindre skadliga gaser. En mindre känd katalytisk process somIn this thesis, in situ ambient pressure X-ray photoelectron spectroscopy has been used to address chemical reactions on surfaces. The presented work aims at the investigation of the relation between pressure and adsorbate surface structures during catalytic reactions. Various materials have been investigated ranging from single crystal surfaces to an immobilized homogeneous catalyst in an effort

Prepositions already formed a grammatical category in the Common German language. New Scandinavian pepositions were established during the preliterary and the early literary periods. In this paper it is demonstraed that most of them were grammaticalizations of prepositional phrases or adverbs linked to a noun by an established preposition. The genesis of these new prepositions is investigated sema

BACKGROUND: Multifocal electroretinogram (mfERG) has the power to discriminate between localized functional losses and overall retinal changes when evaluating retinal injury. So far, full-field ERG has been the gold standard for examining retinal ischemia and the effects of different neuroprotectants in experimental conditions. The aim of the present study was to establish mfERG, with simultaneous

An adaptive controller is proposed and analyzed for the class of infinite-horizon optimal control problems in positive linear systems presented in (Ohlin et al., 2024b). This controller is derived from the solution of a “data-driven algebraic equation” constructed using the model-free Bellman equation from Q-learning. The equation is driven by data correlation matrices that do not scale with the n

A novel pre-purification method was developed for producing peroxidase to guarantee high purity and yield from plant cell cultures in large-scale process. This method was a simple and efficient procedure for the isolation and pre-purification of peroxidase from the biomass consisting of active clay treatment, followed by cationic exchange chromatography. The use of active clay in the pre-purificat

The art of living and the art of eating: Professor Linnaeus recommends. By Gunnar Broberg. As professor of medicine, Linnaeus taught dietetics. He followed the pattern outlined by Galen and Regimen salernitatis, adding an extensive material originating from general cultural history and his own experience.Early in his life he wrote Diaeta naturalis, a collection of rules focusing the blessings of n

The Swedish inventor Christopher Polhem had an idea of a universal language which occupied him for decades, i.e. a perfect language which can be spoken and understood by everyone, by the educated and non educated alike, and no matter where they come from. Polhem did a large number of sketches for such a universal language, among others a manuscript concerning a lunar language, which was completely

Sammanfattningsvis kan Självbestämmandeteorin (SDT) tillämpas av lärare för att stärka elevers motivation och välbefinnande. Däremot är det inte säkert att alla elever därigenom kommer att höja sin inre motivation eller sina studieresultat. Vissa elever är helt ointresserade av vissa ämnen och i avsaknad av motivation krävs mer än att tillämpa SDT. Vidare kan inte enbart ett förändrat klassrumskli

University students’ conceptions of differentiability, continuity and relationsbetween these concepts were studied to reveal their choices of representationsand their strategies to justify their relational claims. Questionnaires and interviews were used to collect data. The results were analysed and categorizedthrough a framework based on understanding as connections between concepts,and a theory

This essay argues that an important factor behind the emergence of a rabbinic form of Judaism was a challenge to Jewish identity and self-understanding posed by Jesus-oriented groups who had appropriated essential aspects of Jewish self-understanding. The unease with gentile attachment to Israel’s God and involvement with the Torah, and the reconfiguration of the boundaries of Judaism to exclude J

The chapter examines what peace looks like from the working levels of the Nordic countries. Several researchers have proclaimed a common Nordic approach to peace and conflict resolution “dead”. However, through interviews focusing on the working level, we find that the Nordics in fact work very closely together in practice, especially in the field in conflict-affected areas. This work is generally

This project evaluates the impact of interior insulation on external walls in three Swedish heritage buildings. Field measurements and hygrothermal simulations were conducted to assess available solutions. Measurements of temperature and relative humidity were taken both indoors and outdoors, as well as on the exterior and interior surfaces of the walls. The accuracy of simulation standards for in

Linkage and candidate gene studies have identified several breast cancer susceptibility genes, but the overall contribution of coding variation to breast cancer is unclear. To evaluate the role of rare coding variants more comprehensively, we performed a meta-analysis across three large whole-exome sequencing datasets, containing 26,368 female cases and 217,673 female controls. Burden tests were p

More complex understanding of relationality in care networks around patients with life-limiting illness and their significant others is needed. This is the case not only because care is distributed unequally along gendered lines, but also because of the changing landscape of care in welfare states where families and communities are made more self-responsible. This study examines everyday experienc
