Status of the MAX IV Storage Rings

In 2009 the MAX IV facility was granted funding by Swedish authorities. Construction of the facility will begin this summer and user operation is expected by 2015. MAX IV will consist of a 3.4 GeV linac as a driver for a short-pulse radiation facility (with planned upgrade to a seeded/cascaded FEL) as well as an injector for two storage rings at different energies serving user communities in separ

A Comparative Analysis Between Different Detection Schemes in Flat Rayleigh-Fading Channels

We compare the performance of different detection schemes in terms of resulting pairwise error probability in Rayleigh-fading channels. We introduce a unified analysis framework used to compare sensitivity to Doppler and noise. The analyzed methods include: pilot symbol assisted modulation, differential detection, multiple-symbol differential detection and detection using superposed pilot symbols.

Abstract in Danish Kapitlet indkredser, beskriver og problematiserer begrebet patientologi. Patientologi betyder videnskab om det at være patient; altså viden der sigter på at gøre os klogere på det at være patient; ikke viden der i første instans sigter på at gøre noget bedre eller anderledes for patienter inden for et fags rammer. Med afsæt i amerikaneren Pamela Brink kan patientologi forstås so

Med Lenin på byrån - normer kring klass, genus och sexualitet i den svenska kommunistiska rörelsen 1921-1939

The thesis Med Lenin på byrån (With Lenin on the drawer) studies magazines produced by the Swedish communist movement during the inter-war years and has two aims; firstly to determine if (and how) class-norms were constructed through descriptions of gender and sexuality, and secondly if (and how) norms regarding gender and sexuality were constructed through descriptions of class. One of the underl

Novel biologically active compounds by semisynthesis with fungal metabolites

Natural products have been shown to be an important source of novel compounds for the development of new drugs and pesticides. However, many biologically active natural products contain reactive functionalities that make them toxic. By modifying such reactive compounds chemically it is possible to make use of the reactivity to form novel "natural product-like" compounds and at the same time reduce

Tvång och rädsla som äktenskapshinder. Tomás Sánchez De sancto matrimonii sacramento

According to medieval canon law, a marriage could be declared invalid if the consent had been given through force or fear. This ruling was a natural consequence of the insistence on free consent as the only requirement for a valid marriage. It did, however, entail a number of both practical and theoretical problems. It could be difficult to prove force and fear within the family, but also to defin

Vascular Effects of P2 Receptors. Changes in Congestive Heart Failure.

Popular Abstract in Swedish P2 receptorernas roll vid utvecklingen av hjärt-kärlsjukdom I västvärlden orsakar hjärt-kärlsjukdomar mycket lidande och är den vanligaste dödsorsaken i befolkningen. Till gruppen hjärt-kärlsjukdomar kan man räkna hjärtinfarkt, kärlkramp, högt blodtryck, hjärtsvikt och slaganfall. En gemensam komponent i sjukdoms-utvecklingen är en förändring i blodkärlsväggen som gör Extracellular nucleotides induce dilatation and constriction of blood vessels by activation of P2 receptors. In this thesis the vasomotor effects of P2 receptor activation were studied in the rat mesenteric artery, and their changes in congestive heart failure (CHF) were evaluated using in vitro pharmacology, electrophysiology and competitive RT-PCR. Vasodilatation was induced by activation of P2Y

Numerical study of swirling impinging jets with heat-transfer

This paper deals with numerical simulations of circular impinging jets with heat transfer, by means of Large Eddy Simulation (LES). The LES code uses higher order finite-differences on staggered Cartesian non-uniform grids. The current LES have the potential of dealing with transition as well as providing data on details of larger scale structures, statistical correlations and turbulent spectral c
