The measurement of absorbed dose distributions using dosemeter gel and magnetic resonance imaging (MRI) in a standard geometry has been investigated. Absorbed depth-dose curves and profiles measured with this new technique show good agreement with corresponding measurements using diodes. This was proven in a 60Co beam as well as an electron beam. The dosemeter gel is made of agarose and ferrous su

The Gaia-ESO Survey is an European Southern Observatory (ESO) public spectroscopic survey that targeted 105 stars in the Milky Way covering the major populations of the disk, bulge and halo. The observations were made using FLAMES on the VLT obtaining both UVES high (R ~ 47 000) and GIRAFFE medium (R ~ 20 000) resolution spectra. The analysis of the Gaia-ESO spectra was the work of multiple analys

Personalized patient care has gained increasing attention in recent years. Precise drug dosing is critical for patient safety and good clinical outcomes, especially in intensive care units, where patients often are in critical conditions. Such treatments can include stabilizing blood pressure and heart rate or maintaining safe anesthesia levels. However, the inter-patient variability in the drug r

In February 1825, the dikes broke after a spring tide in the Krummhörn region in East Frisia, Germany, causing a severe disaster. Although the flood did not claim many victims, substantial damage was done to the farmland, and the economic crisis that followed permanently changed the social structure in the Krummhörn. We study family reconstitutions of the region linked to information about socioec

Med utgångspunkt i unikt arkivmaterial undersöker denna avhandling skillnader i hur västliga demokratier styrt radio och television. Genom en jämförande studie av fyra länder följer den de intressekonflikter som präglat etermediepolitiken — från de tidigaste radioregleringarna till kabel- och satellit-tv:s genomslag under slutet av nittonhundratalet.Snarare än att tolka politiska konflikter kring Using original archival evidence, this doctoral dissertation describes and explains differences in how Western democracies have governed radio and television, tracing interest group struggles over broadcasting in four countries from early radio policy to the rise of cable and satellite television in the late twentieth century.Rather than framing political conflicts over radio and television as a b

During the evolution of parasites, co-speciation and host-range expansion are thought to play roles in establishing associations with hosts, while sorting events can lead to dissolution of those associations. To address the roles of these processes, we focus on avian haemosporidian parasites infecting hosts of the intensively studied great tit species complex. We estimated the phylogeography of li

Cellulär kommunikation utvecklas ständigt; för närvarande installeras 5G-system och forskning kring 6G pågår. Tre användningsfall som diskuteras är enhanced mobile broadband (eMBB), massive machine-type communication (mMTC) och ultra-reliable low-latency communication (URLLC). För att uppfylla kraven i dessa användningsfall behövs ny teknik och en kandidat är massive multiple-input multiple-outputCellular communication is constantly evolving; currently 5G systems are being deployed and research towards 6G is ongoing. Three use cases have been discussed as enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable low-latency communication (URLLC). To fulfill the requirements of these use cases, new technologies are needed and one enabler is massive mult

In 2012, The Basel Committee on Banking Supervision decided to change the standard risk measure from the well-known Value-at-Risk (VaR) to Expected Shortfal (ES). The committee believes that the new standard risk measure could offer more benefit, aside from just overcoming the major weaknesses of VaR like incoherency and inability to capture tail risk. In this study, best models for VaR and ES are

When costumers look for a robot for their factory two things are important. The robot should be as efficient as possible, but still be cheap. In order to make the robot efficient the robot-controller has to know the dynamics of the robot and its limits. Based on these it can then generate a time-optimal plan (trajectory) for each movement. The standard way of generating a time-optimal trajectory w

Abstract The ESSSB (European Spallation Source Neutrino Super beam) is a proposed long baseline neutrino oscillation experiment, intended to use the same proton accelerator as the European Spallation Source. With the pro- posed modications to the accelerator both ESSSB and the ESS would achieve a beam power of 5 MW. This power, in conjunction with the dis- covery of a large value of the mixing ang

Abstrakt Self-harming patients is a problem nurses’ faces in their everyday work. In Sweden approximately 7800 people is hospitalised due to self-harm. The aim of this study is to examine what factors influences nurses’ attitudes and care towards patient who self-harm. This study reviewed previous studies on this subject and collected nine articles that had relevance towards the aim. The result fo

The informal sector is often seen as one sector with the potentials to transform the economies of developing countries if well harnessed. This is particularly true in the case of Nigeria where the informal sector creates employment opportunity for a large number of the labor force compared to the formal sector economy. However, it is also pertinent to bear in mind that the informal sector is often

Rapporter om rekordlåga grundvattennivåer och införda vattningsförbud blir vanligare och vanligare. En av de kommuner som har haft problem med dricksvattenförsörjningen är Gävle kommun. De har, via ett samarbetsorgan, anlitat Midvatten AB för att kartlägga förutsättningar för att inrätta en ny dricksvattentäkt i Älvkarleby-Skutskär. I det aktuella området löper Uppsalaåsen, som innehåller mycket gSweden has in recent years suffered record-low groundwater levels with imposed water restrictions. One of the municipalities who have had problems with their drinking-water supply is Gävle. They have hired Midvatten AB to review a possible location that for groundwater extraction in Älvkarleby-Skutskär. The Uppsala Esker, which contains a lot of groundwater, passes through the area. Parallel to th

There is empirical evidence indicating that trust in research is decreasing. If distrust is justified, this is a good thing; if not, it is a cause of concern. A basic question concerns the reasons for, ant the causes of, distrust. Which are they, what do they mean, and how reliable are they? The papers and presentations in this volume focus on external and internal factors contributing to distrus

This dissertation looks into the treatment of exposed children and young people. The background is a puzzlement as to how the discourse on treatment, during the latest twenty years, has concentrated on the same institutions and themes (Ebsen, 2007). The aim of the dissertation is to shed light on how the institutions of child saving, (family care, placement in residential care, intervention in the

In this study doctoral students in psychology and social anthropology/ethnology were interviewed as to their selection of research problem for their Ph.D. thesis. From the perspective of activity theory it is suggested that the research problem can profitably be seen as the object of activity in research. Graduate students’ selection of a research problem was analyzed as a process occurring over t
