Popular Abstract in Swedish Denna avhandling handlar om akustofores, dvs. om hur ultraljud kan användas för separation av celler och mikroskopiska partiklar i en ytterst smal flödeskanal. Separationen kan handla om att man vill separera en typ av celler från en annan, som till exempel när man letar efter s.k. cirkulerande tumörceller i blodprover från cancerpatienter. I ett annat fall så vill man This thesis presents experimental studies of microchannel acoustophoresis, a technique for manipulation of microscopic objects in suspension by means of acoustic radiation forces induced by ultrasonic standing wave fields. By arranging an acoustic resonance across the width of a microchannel, the path of individual cells or microparticles can be deflected orthogonally to the fluid flow. The prop

When skeletal muscle is stretched above optimal sarcomere length during tetanic activity there is an increase in force that stays above the isometric force level throughout the activity period. This long-lasting increase in contractile force, generally referred to as "residual force enhancement after stretch" (Fresid), has been studied in great detail in various muscle preparations over more than

The purpose of the present paper is to outline emerging trends in nanomedicine, as well as to discuss some of the potential benefits and problems the medical applications of nanotechnologies may give rise to. In the paper some of the suggestions recently made by the European Group on Ethics in Science and New Technologies concerning how to deal with some of these problems are presented. I conclude

Miljardmarknad med dödliga konsekvenser. Falska mediciner är ett nästan okänt hälsohot för svensk allmänhet, trots att de dyker upp bland läkemedel som köps på internet. Andelen svenskar som handlar mediciner på nätet ökar. Nu krävs tydlig och återkommande information om farorna med förfalskningar, skriver Susanne Lundin.

We previously described and showed that the method for cardiac de-airing involving: (1) bilateral, induced pulmonary collapse by opening both pleurae and disconnecting the ventilator before cardioplegic arrest and (2) gradual pulmonary perfusion and ventilation after cardioplegic arrest is superior to conventional de-airing methods, including carbon dioxide insufflation of the open mediastinum. Th

This thesis consists of four essays discussing network structures and institutions in financial markets. The first essay explores the determinants of the egocentric lending networks of stock listed companies in China. Egocentric lending networks are constructed using the public loan announcements of firms listed on China’s two stock exchanges combined with cross-ownership shares connecting the len

Information about the equivalent current distribution on a radome can be used to improve radome design, detect manufacturing errors, and to verify numerical simulations. In this paper, the transformation from near-field data to the equivalent current distribution is analyzed. The transformation is based on a singular value decomposition of the surface integral equation that relates the equivalent

Apses with meaning: A reply on the criticism by Christian Lovén on my interpretation of the symbolism of the Romanesque apse at churches in Scandinavia. Lovens critism is published in the perodical Fornvännen 2009: 3. My interpretation of the apse primarily as a symbol of Heaven, but also as a symbol of the sovereignty of the bishop is published in the periodical Hikuin (Wienberg 1997).

Abstract in Danish Blandt geografer huskes Gudmund Hatt nok især som professoren, der efter besættelsen blev afskediget for „uværdig national optræden“. Det skyldtes ikke mindst de „tyskvenlige“ geopolitiske analyser, han som en del af samarbejdspolitikken udfoldede i radioen og i det Berlingske Blade. Nogle vil måske også huske Hatt for de lidet flatterende racistiske passager i Jorden og Mennesk
