Spectroscopic Investigations of Highly Charged Tungsten Ions - Atomic Spectroscopy and Fusion Plasma Diagnostics

Popular Abstract in Swedish Atomspektra har varit ett viktigt forskningsområde inom fysiken sedan mitten av 1800-talet. Då elektromagnetisk strålning, såsom synligt ljus, ultraviolett- och röntgenstrålning, är unik för varje grundämne ger ett observerat spektrum information om vilka slags atomer som emitterar strålningen. Exempelvis så visar spektra av ett vanligt lysrör att ljuset kommer från kviThe spectra of highly charged tungsten ions have been investigated using x-ray and extreme ultraviolet spectroscopy. These heavy ions are of interest in relativistic atomic structure theory, where high-precision wavelength measurements benchmark theoretical approaches, and in magnetic fusion research, where the ions may serve to diagnose high-temperature plasmas. The work details spectroscopic in

High performance MRI simulations of motion on multi-GPU systems

Background: MRI physics simulators have been developed in the past for optimizing imaging protocols and for training purposes. However, these simulators have only addressed motion within a limited scope. The purpose of this study was the incorporation of realistic motion, such as cardiac motion, respiratory motion and flow, within MRI simulations in a high performance multi-GPU environment. Method

Is bone mineral density advantage maintained long-term in previous weight lifters?

This cross-sectional study was done in order to ascertain whether there is a lifelong beneficial effect on bone mineral density (BMD) of early, long-lasting, and intense physical exercise. Forty-eight male ex-weight lifters, mean age 64 years (range 50-79) participated. They had followed a training program of an average of 10 hours/week (range 4-20) for an average of 13 years (range 1-34). They ha

Electrophysiological studies in newly onset type 2 diabetes without visible vascular retinopathy.

Seventeen patients with newly diagnosed type 2 diabetes (duration 7 ± 3 months), without any vascular retinopathy in fundus photographs, were examined with full-field electroretinogram (ERG) and multifocal ERG

Aspects on Interference and Diversity in Wireless Networks

Popular Abstract in Swedish Denna avhandling behandlar två ämnen inom trådlös kommunikation: interferens mellan frekvenshoppande (FH) nätverk och fleranvändardiversitet. I arbetet på FH nätverk undersöks ett system där frekvenshopp används för att möjliggöra samtidig tillgång till kanalen för multipla okoordinerade nätverk. Detta åstadkoms genom att frekvenshoppen sker varje gång ett ny paket skaThis thesis deals with two topics in wireless communications: interference between frequency-hopping (FH) networks, and multiuser diversity. The work on FH treats a system where FH is used to provide simultaneous access to the channel for multiple uncoordinated wireless networks. This is achieved by performing frequency hops on a packet-by-packet basis, and letting the sequence of hopping frequen

The Formation of Green Identities - Consumers and Providers.

Liberalisation and deregulation of public utility sectors has been introduced in several European countries. In 1994 Swedish municipalities were instructed to reorganise waste collection routines by enlarging the number of fractions to be able to reuse waste fractions in an environmental benign way. The public waste sector have to a considerable extent been diversified and deregulated. At the same

Strengths and weaknesses of the aniline-blue method used to test mushroom (1→3)-β-D-glucans obtained by microwave-assisted extractions

The parameters to extract polysaccharide-enriched fractions (PEF) from mushrooms using MAE (microwave-assisted extraction) were adjusted following a full factorial 3 2 experimental design. The highest yield and total carbohydrate values, using Lentinula edodes as model mushroom, were obtained at 180 °C and 30 min. Several mushroom species were submitted to MAE and their PEF yields ranged between

Background Studies of the High-Intensity Baryon Extraction and Measurement (HIBEAM) Experiment at the European Spallation Source

The High-Intensity Baryon Extraction and Measurement experiment (HIBEAM) is proposed as one of the experimental stations at the European Spallation Source (ESS). This experiment will mainly focus on the neutron into sterile neutron oscillations which violate the baryon number (B) by one unit. The sterile neutrons are hypothetical dark matter candidates. The neutrons suitable for the experiment hav

Conjunctures of eco-social partnership unionism : The German Trade Union Confederation’s climate policies over three decades

The article analyses the climate policy of the German Trade Union Federation over the last 30 years. It defines a new form of eco social partnership unionism where unions use existing institutions to adapt to the challenges of climate change without embarking on more transformative avenues questioning the status quo. We show that unions climate policy has been subject to little change over the pas

Security of Electricity Supply – An Investigation of National Measures Aimed at Ensuring a Secure Supply of Electricity and their Compatibility with EU Law

Energipolitik har varit och är fortfarande av stor betydelse både för Medlemsstaterna och för EU. Behovet av att trygga en säker och pålitlig energiförsörjning är en central aspekt av en gemensam energipolitik. De senaste decennierna har det på EU-nivå pågått ett arbete att utveckla en enhetlig och samordnad strategi ämnad att trygga en säker elförsörjning inom EU. Några viktiga aspekter i EU:s stEnergy policy is a policy area of great significance for the Member States and for the EU. An integral part of every energy policy is the need to ensure a secure supply of electricity. At EU-level, the challenges to security of supply are to be managed via a coherent and coordinated approach aimed at taking into account the interest of the Union. Demand management, the further integration of the i

Modelling radiation damage to pixel sensors in the ATLAS detector

Silicon pixel detectors are at the core of the current and planned upgrade of the ATLAS experiment at the LHC. Given their close proximity to the interaction point, these detectors will be exposed to an unprecedented amount of radiation over their lifetime. The current pixel detector will receive damage from non-ionizing radiation in excess of 1015 1 MeV neq/cm2, while the pixel detector designed

Electron transport in InAs nanowires and heterostructure nanowire devices

Nanowires in the InAs/InP material system are grown with catalyst-assisted chemical beam epitaxy. Ohmic contacts are then fabricated to selected wires, allowing electron transport measurements to be carried out at room-temperature as well as at low T. InAs nanowires show strong quantum confinement effects, where thin wires (<30nm) are depleted from carriers. Measurements on InAs wires with a quant
