The paper explores ideas as to what Bronze Age barrows could have symbolized in the society in which they functioned as living symbols. Four possible concepts are discussed: continuity, collective, context, and hierarchy. Source material is taken from five areas in Scania where there is adequate data from excavated barrows to test the ideas: southern Halland, the parish of Raus, the island of Ven,
Law should be the expression of the collective will, and the regulative sphere becomes therefore a highly consensual field supposed to reflect generally agreed norms and values. Although it is generally admitted that genetic and biotechnology developments can contribute to immense benefits within the health-care sector, the exponential globalisation trend and the rapid pace of scientific and techn
Adsorption of several surface active agents, such as nonionics, diblock copolymers, triblock copolymers, proteins and phospholipids at the oil/water and air/water has been studied. In order to be able to do this, a new ellipsometry setup, which utilizes light guides, was developed and tested. A new evaluation methodology was developed and tested as well. This methodology is based on performing ea
Anticoagulant protein C is a vitamin K-dependent factor circulating in plasma as a zymogen of a serine protease. It is converted to its active form (APC) by the thrombin-thrombomodulin complex on the surface of endothelial cells. APC inhibits the generation of thrombin by selective proteolytic inactivation procoagulant factors Va and VIIIa. Protein S, another vitamin K-dependent protein, serves as
There are similarities among various transport processes in solid oxide fuel cells (SOFCs) and proton exchange membrane fuel cells (PEMFCs), but also some differences. The present work concerns modelling and numerical analysis of heat, mass transfer / species flow, two-phase transport and effects on the cell performance in SOFCs and PEMFCs. Numerical calculation methods are further developed to en
With the recent expansions of the European Union, there are now 12 new member states that are implementing European policy. One of these policies, with implications for energy production and security, is the Common Agricultural Policy. This article will focus on the impact the Common Agricultural Policy can have on farmers in Poland who have been encouraged by calls to cultivate energy crops. In a
Popular Abstract in Swedish Bukspottkörteln består av exokrin och endokrin vävnad. Den exokrina vävnaden utsöndrar en bukspottsaft rik på enzymer som hjälper till att bryta ner vår föda i mindre beståndsdelar. Den endokrina vävnaden insöndrar hormoner som hjälper till att reglera sockernivåerna i blodet. Det främsta hormonet som reglerar blodsockret är insulin, som bildas och insöndras från insuliThis thesis deals with the expression, localization and regulation of neuropeptide Y (NPY) in the pancreatic islets of Langerhans under normal and experimental conditions. NPY is widely distributed in the mammalian nervous system and belongs to a family of closely related petides also comprising peptide YY (PYY) and pancreatic polypeptide (PP). NPY exerts a variety of biological effects, such as s
In this study the deactivation of Pt/wire mesh and vanadia/monolith catalysts by aerosol particles of some inorganic salts (K2SO4, KCl and ZnCl2) with high or low melting points has been investigated. The aerosol particles may either diffuse within the matrix of the catalysts and block the mezzo and micro pores, or deposit on the outer surface of the catalysts and form a porous layer causing a mas
We propose a technique to integrate core selection in the SOC (system-on-chip) test solution design-flow. It can, in contrast to previous approaches, be used in the early design-space exploration phase (the core selection process) to evaluate the impact on the system's final test solution imposed by different design decisions, i.e. the core selection and the cores test characteristics. The propose
