The optimisation of image quality vs. radiation dose is an important task in medical imaging. To obtain maximum validity of the optimisation, it must be based on clinical images. Images at different dose levels can then either be obtained by collecting patient images at the different dose levels sought to investigate-including additional exposures and permission from an ethical committee-or by man
The European project has come a long way in establishing peace, creating a common market, and expanding its borders. At the same time, diminishing popular legitimacy has spurred talk about a European Union in crisis. How far has the EU really come in fulfilling its grand visions? Is the project barely half-way? Or could we say with some confidence that European integration is solidified and will c
Aim: To describe fathers’ lived experiences of caring for their preterm infant at the neonatal unit and in hospital-based neonatal home care after the introduction of an individualised parental support programme. Method: Seven fathers from a larger study were included due to their rich narrative interviews about the phenomenon under study. The interviews took place after discharge from neonatal ho
Background: There is still a lack of knowledge regarding the natural course of resolution of hydronephrosis after pyeloplasty, and no consensus exists on how resolution of hydronephrosis is defined or when resolution is expected to occur. Objective: To determine when resolution of hydronephrosis occurs following pyeloplasty, by type of obstruction and by surgical approach. Methods: This retrospect
Orbital magnetization is known empirically to play an important role in several magnetic phenomena, such as permanent magnetism and ferromagnetic superconductivity. Within the recently developed "modern theory of orbital magnetization," theoretical insight has been gained into the nature of this often neglected contribution to magnetism but is based on an underlying mean-field approximation. From
Incommensurate order, in which two or more mismatched periodic patterns combine to make a long-range ordered yet aperiodic structure, is emerging as a general phenomenon impacting the crystal structures of compounds ranging from alloys and nominally simple salts to organic molecules and proteins. The origins of incommensurability in these systems are often unclear, but it is commonly associated wi
Background: Childhood obesity is an urgent public health concern, and there's a need for long-term, high-quality, primary prevention trials targeting parents of young children. The aim of the current study was to evaluate the long-term effect of a parental support program based on motivational interviewing (MI). Methods: A cluster randomized controlled trial was carried out in eight Swedish counti
In their efforts to prevent democratic backsliding, militant democrats have traditionally been sympathetic to technocratic arrangements. Does this sympathy imply a logical congruence? Comparing theories of militant democracy and epistemic technocracy (aka epistocracy), I discover a common approach to basic aspects of representative democracy. Both theories see voters as fallible or ignorant instea
This open access book contributes new theoretical and comparative insights on migrant agency, undocumentedness and informality in non-Western, non-democratic migration regimes. The book is conceived as a critical reflection on the contemporary migration regime scholarship, and, more generally, on comparative migration studies, which primarily focus on migrants’ experiences and immigration policies
The relative environmental impact from the building construction phase is increasing compared to the operation phase for new buildings. Therefore, it is important to consider the complete environmental life cycle of energy improvement measures. Many advanced optimization methods have been developed in recent years to assess building life cycle impact. However, these previous studies have not fully
The ability to move safely between obstacles is critical for animals that fly rapidly through cluttered environments but surprisingly little is known about how they achieve this. Do they reactively avoid obstacles or do they instead fly towards the gaps between them? If they aim towards gaps, what information do they use to detect and fly through them? Here, we aim to answer these questions by pre
This study examines if the Swedish stock market adheres to the weak form efficient market hypothesis using Fourier analysis on past stock prices to identify possible cyclic returns. Fourier analysis is well suited for finding seasonalities which would violate the weak-form efficiency. 10 firms were randomly selected from stock market index OMX30 to represent the Swedish stock market. All firms
Denna masteruppsats syftar till utvecklandet av en industriellt, fullskalig modell över en vattenreningsprocess som syftar till simultan sulfatreduktion och tungmetallåtervinning från processvatten vid gruvdrift. Den mängd sulfat som finns tillgänglig i lakvattnet, omvandlas till vätesulfid med hjälp av sulfatreducerande bakterier (SRB). Tungmetallerna återvinns genom selektiv utfällning med hjälpThis thesis treats the development of an industrial scale models of a wastewater treatment process aiming at reducing the sulfate and heavy metal concentration in the effluent water from mining processes. The sulfate present in the process water is reduced using sulfate reducing bacteria (SRB) while the heavy metals are recovered through selective precipitation using the hydrogen sulfide produced
En av de mest grundläggande principerna inom aktiebolagsrätten och en stark bidragande faktor till dess popularitet återfinns i 1 kap. 3 § ABL, dvs. aktieägare är som huvudregel inte personligt ansvariga för bolagets förpliktelser. Till varje huvudregel finns undantag och så även här. I Sverige har det diskuterats om aktieägare trotsallt ska kunna hållas ansvariga för bolagets förpliktelser genom One of the most fundamental principles of company law and a strong contributing factor to its popularity can be found in chapter 1. article 3 in the Swedish Companies Act, i.e. shareholders, as a general principle, are not personally responsibility for the debts or actions of a corporation. To every general principle exists exceptions, which applies here as well. In Sweden, the question has been r
Syftet med denna uppsats är att undersöka till vilken utsträckning en stat egentligen är bunden till påskrivna traktater och den internationella sedvanerätten. Traktater i grund och botten avtal och det händer att avtal bryts. Frågor som uppsatsen siktar på att svara är vilka möjligheter finns det för en stat att få upprättelse för felaktiga handlingar och vad kan en internationell domstol eller sThe purpose of this essay is to examine to what extent a state really is bound to signed treaties and international customary law. Treaties are in their foundation a contract and it happens that contracts are broken. Questions which the essay aim to answer are which possibilities there are for a state to receive restitution for wrongful acts and what can an international court or arbitration do to
The aim of this study was to investigate how social workers look at the boundaries between their private sphere and working hours. Furthermore, it is intended to study how social workers look at work-related situations that may occur in their leisure time and how they handle them. The selection of respondents consisted of social workers who had a social education and had a regular professional con
This examination addresses the problem of proxy warfare in civil wars by examining Iran’s and Saudi Arabia’s involvement in the Syrian Civil War. Based on previous theoretical frameworks a new theoretical framework of proxy warfare has been developed which is used to analyze whether Iran’s and Saudi Arabia’s involvement in Syria is a case of proxy warfare or not, and if their involvement in the co
