Popular Abstract in Swedish Plasmasprutning är en process för beläggning av tunna skikt av olika material såsom metallegeringar, polymerer och keramer. Användningsområdena är åtskilliga, från titanstekpannor till oxidationskydd och värmeisolerande skikt i JAS planets motor. Plasmasprutnings processen genererar en plasmalåga när en gas, vanligtvis argon, sönderdelas mha elektrisk energi. PlasmalågaThe aim of this thesis is to enhance the overall understanding of the plasma spray process and increase control and reproducibility of the coating properties. This was performed by establishment of relationships between controllable process parameters, in-flight properties of the injected particles (velocity and temperature), and microstructure properties. The relationships were used to establish

Popular Abstract in Swedish Allt liv på jorden bygger på fotosyntesen. Det är den process där växterna fångar upp solljuset och gör om det till kemisk energi. Med den energin producerar de syret i luften och kolhydrater för sin egen tillväxt, med kol från luftens koldioxid. Djuren äter kolhydraterna och förbränner dem med hjälp av luftens syre, samtidigt som de andas ut koldioxid. På detta sätt leIn this work the lateral heterogeneity of the thylakoid membrane was investigated by quantifying the amount of photosystem I (PSI), photosystem II (PSII) and some PSII complexes and PSII proteins in different domains of the thylakoid. Grana, grana core, grana margins and stroma lamellae + end fractions were obtained by sonication and separation in a non-detergent, aqueous polymer two-phase system

The paper deals with various initiatives undertaken, or to be undertaken, by Government of Botswana, and which may be looked upon as "Information Society" initiatives. These initiatives are critically analysed and conclusions are drawn from the authors' analysis. Based on conclusions, the authors make certain recommendations regarding implementation of the initiatives.

Enterprise resource planning (ERP) systems are rapidly becoming a de facto standard in business activity. While large and medium-sized companies have the luxury to afford proprietary ERP solutions, small companies are struggling with resource poverty which maybe makes them consider available open source ERP products which are free from licensing fee. However, there is little knowledge available on

Popular Abstract in Swedish Höftfraktur är en vanlig skada, som huvudsakligen drabbar äldre kvinnor, och oftast orsakas av ett ringa våld. Det är vanlig orsak till funktionsnedsättning, sjuklighet och dödlighet hos de äldre. Både incidensen (antal nya fall per antal innevånare och år) av höftfrakturer och det totala antalet har ökat de senaste årtiondena. Höftfrakturer medför stora kostnader för sHip fractures are a common cause of morbidity and mortality in elderly patients, with a high risk of functional impairment and institutionalization. The incidence and number of hip fractures have increased during the recent decades and hip fractures consume considerable health-care resources. The incidence of hip fractures in Malmö, Sweden, 1992–95, is described in Paper I. The annual incidence pe

14-3-3 proteins comprise a family of highly conserved proteins. 14-3-3 proteins have been found in all organisms examined except for members of the prokaryotic kingdom. 14-3-3s are involved in numerous processes in the cell and they typically bind to phosphorylated motifs in other proteins and regulate their activities. In plants, 14-3-3 proteins are recognized as key regulators of primary metabo

It has often been argued that the Earth is like an island in space and that its brittleness is most clearly reflected on small islands in the oceans. Easter Island, in particular, with its largely depleted resources, has been seen as a microcosmic warning about what could happen to our entire planet. However, the analogy of the Earth and islands with finite natural resources is not self-evident fr

Based on how the mushroom Lactarius vellereus converts an inactive precursor into the cytotoxic dialdehyde isovelleral (1) via a cyclic enol ether, as part of a binary chemical defense system that protects the fruit bodies against parasites, a synthetic way to obtain analogous dialdehydes masked in the same way has been developed. As isovelleral analogues (e.g. 2 and 3) possess extremely potent cy
