A binary mixture model for soils has been formulated and analyzed. In the model one of the constituents is soil and the other constituent an incompressible liquid. The effects of water are included by formulating a mixture model is formulated as an extension of an existing non-associated elasto-plastic material model for granular materials. This paper is focused on the balance of momentum equation

We have recently reported that the inner layers of the arteries, the intima-media complex, of common carotid artery, move as much in the longitudinal direction as in the radial direction, during the cardiac cycle. In order to study this phenomenon we have developed a high-resolution ultrasonic method that can simultaneously record both the longitudinal and the radial movements of the arterial wall

Popular Abstract in Swedish Min avhandling är en s.k. sammanläggningsavhandling och innehåller fyra delarbeten (I-IV), vilka alla är publicerade i vetenskapliga tidskrifter. I delarbetena redovisas undersökningar av två enzymer, hormonkänsligt lipas (HKL) och proteinkinas B (PKB). HKL är ett sedan länge välkänt enzym, vars huvudsakliga uppgift är att spjälka fett (triglycerider) som lagras i fettcHormone-sensitive lipase (HSL) and protein kinase B (PKB) are enzymes that in different ways are associated with lipid metabolism. While HSL is the well-known lipolytic enzyme responsible for hydrolysis of stored triacylglycerols in adipose tissue, PKB is a recently identified serine/threonine protein kinase, ubiquitously expressed and involved in signal transduction pathways induced by insulin an

The amount of electrical loads and the complexity of the electric system in a vehicle is increasing at the same time as the allowed development time is decreasing. Possibilities to predict the electromagnetic behaviour is therefore of great importance. This paper addresses the problems of low frequency electromagnetic crosstalk between cables in a harness. Analytical expressions for estimation of

Popular Abstract in Swedish Ett nytt och experimentellt sätt att bota eller lindra sjukdomssymptom är att, istället för att tillföra en medicin, rätta till felet på en genetisk nivå. Detta kan åstadkommas genom att överföra nya, fungerande gener, sk transgener, till celler som då börjar producera protein, som i sin tur kan ge upphov till en terapeutisk effekt. I hjärnan skulle denna typ av behandlThe use of genetically modifi ed neural stem and progenitor cells could possibly be a future strategy for repairing a brain suffering from neurodegeneration. However, so far it has proven diffi cult to maintain sufficient levels of a transferred gene in suitable cell types, after transplantation. In the present thesis I studied the silencing of transgenes induced upon differentiation of neural pro

This article describes results of the work on knowledge representation techniques chosen for use in the European project SIARAS (Skill-Based Inspection and Assembly for Reconfigurable Automation Systems). Its goal was to create intelligent support system for reconfiguration and adaptation of robot-based manufacturing cells. Declarative knowledge is represented first of all in an ontology expressed

The current work of developing a control simulation benchmark goes back to the work carried out within the COST Action 682 (“Integrated Wastewater Management”) and the IAWQ Task Group on Respirometry-Based control of the Activated Sludge Process in the late 90s. The work was continued in COST Action 624 until 2003 (Copp 2002). In 2005, the IWA Task Group on Benchmarking of Control Strategies for W
