The main objectives with this investigation are firstly to compare important parameters of a capacitive micromachined ultrasonic transducer (cMUT) for air applications with a corresponding piezoelectric ultrasonic transducer. Secondly, to characterise the cMUT's radiation field using light diffraction tomography. The cMUTs consist of a silicon backplate with small pyramid-shaped cavities and a met

The biological functions of proteins depend on their physical interactions with other molecules, such as proteins and peptides. Therefore, modeling the protein-ligand interactions is important for understanding protein functions in different biological processes. We have focused on the cleavage specificities of HIV-1 protease, HCV NS3 protease and caspases on short oligopeptides or in native prote

The aim of the present study is to contribute to the documentation and interpretation of the image and experience of the human body. This image was first formulated in the 16th and 17th centuries by among others René Descartes, and it was given various visual shapes by artists connected with the academies of art from that time on. The intention of my investigation is to discuss some traits of what

Geophysical methods are increasingly being applied to geotechnical investigations, as they can identify material properties and material boundaries, as well as variations in space and time of relatively large volumes of soil. Another advantage is that many of these methods are non-intrusive. The combination of several methods and the verification of their results by sampling and correlating with g

Popular Abstract in Swedish Många idéer cirkulerar kontinuerligt inom och mellan olika fält i samhället. En del av dessa idéer blir på modet och betraktas som legitima lösningar på olika slags problem. Bland dessa kan organisationer – såväl offentliga som privata - lätt hitta färdiga paketlösningar till hur de exempelvis skall styra, leda eller budgetera sin verksamhet. Kvalitetssäkring blev en såThe aim of this study was to expand our understanding of the processes of institutionalisation both within and between organisational fields. This was done by tracing an idea – the idea of quality assurance – through the process of institutionalisation in the health care sector. The new institutional theory, which focuses on the relation between organisations and the institutions they are consider

Popular Abstract in Swedish Nanoteknologi är en ung vetenskap där man sysslar med strukturer som är större än molekyler men mindre än ett tusendels hårstrå. Förklaringen till att nanoteknologi etablerats som ett nytt begrepp finner sin grund i att vid dessa dimensioner beter sig material på sätt som varken kan beskrivas rent kemiskt eller är lika bulkegenskaper. Nya egenskaper gör entré. Det sättA new approach to the study of nanoparticle systems has been introduced. Nanoparticle systems in aqueous and organic solutions have been synthesized and studied by transmission electron microscopy. These systems include nanoparticles of gold, silver, palladium, ruthenium, and platinum which have been stabilized using various ligands. The particles were initially studied as deposited samples on ca

Aquaporins are integral membrane proteins that function as water channels highly specific for water or as aquaglyceroporins permeable to water as well as small solutes such as glycerol and urea. The model plant Arabidopsis thaliana has 35 genes encoding aquaporin proteins. Identifying the complete set of aquaporins in Arabidopsis constitutes an unique opportunity to comprehensively classify and re

When God moves out - the deserted churches of Mårup and Maglarp: A discussion on the fate and future of deserted churches since the Middle Ages in mainly Scandinavia. The article is departuring from the case of Mårup in Jutland (Denmark) and Maglarp in Scania (Sweden), which were demolished 2007-08.
