Partially Premixed Combustion is a concept able to combine low smoke and NOx emissions with high combustion controllability and efficiency. It is of interest to be able to utilize PPC in a large operating region in order to meet the Euro VI emission legislation without relying on NOx aftertreatment. This paper investigates the differences in PPC characteristics for three fuels; Diesel Swedish Mk
Den här fallstudien undersöker hur Rädda Barnen arbetar opinionsbildande i sin kampanj för att få hem de svenska barnen med föräldrar som har IS-kopplingar från Syrien. Studien har gjorts i syfte att få förståelse för hur Rädda Barnen använder sig av medier för att bedriva sitt kampanjarbete och sätta sig själva och de frågor de bedriver på agendan. Vi har genomfört en studie där vi analyserat fle
This thesis work concerns methods for improved spectroscopy including stray-light suppression, dynamic range improvement and signal enhancement. These methods were applied in Raman and Thomson- scattering spectroscopy in combustion and plasma. First, the stray-light suppression method Periodic Shadowing (PS) is implemented in an experimental setup with a high-power high repetition rate laser syste
Prior to the accomplishment of this research, the compatibility of the classic e-servicescape conceptual model in the context Taobao and TMall in China were rarely found among existing e-servicescape literatures due to the standardization taken by both online platforms towards the establishment of individual webshops. Meanwhile, the conceptualization of social factors as social dimension of e-serv
This thesis argues that general subordinators, such as the Germanic THAT and IF, denote propositional modality. Propositional modality stands for the “speaker’s attitude to the truth-value or factual status of the proposition” (Palmer 2001:24) and is otherwise expressed by moods such as the indicative-subjunctive and epistemic-evidential modal markers. One obvious connection between markers of pro
A fracture risk assessment tool (FRAX (TM)) is developed based on the use of clinical risk factors with or without bone mineral density tests applied to the UK. Introduction The aim of this study was to apply an assessment tool for the prediction of fracture in men and women with the use of clinical risk factors (CRFs) for fracture with and without the use of femoral neck bone mineral density (BMD
The actual concept of food security focuses on four food security dimensions: food availability, food access, food utilization and food stability of which eight indicators were identified for this study. The study aims to evaluate vulnerability to chronic food and nutrition insecurity, one of the food stability types, in Ethiopia; and examines the relationship between four food security dimensions
We studied bacterial and fungal colonization of submerged plant litter, using a known Si-accumulator (Equisetum arvense), in experimental microcosms during one month. We specifically addressed the microbial decomposer role concerning biogenic silica (bSiO2) dissolution from the degrading litter. To vary the rates and level of microbial colonization, the litter was combined with a range of mineral
We present a Bayesian ideal observer model that estimates observer translation and rotation from optic flow and an extra-retinal eye movement signal. The model assumes a rigid environment and noise in velocity measurements, and that eye movement provides a probabilistic cue for rotation. The model can simulate human heading perception across a range of conditions, including: translation with simul
Sexual and Reproductive Health and Rights (SRHR) emerged from a fragmentation of different meaning of SRHR coming together to form one complex policy area. SRHR has been politicized in the past by predominant activist groups such as human rights and feminists (including those working with both fields simultaneously). Politicization refers to the process by which an issue becomes prominent in a giv
This study analyzes the personal identification process that takes place in the actual meeting of a job coach and a job seeker, with the purpose of making the job seeker employable. The empirical data consists of observations during nine job coach meetings, and interviews with four job coaches. The analysis is based on a social constructionist perspective. The findings point to contradictions in t
Popular Abstract in Swedish Bakgrund: Sedan Wilhelm Conrad Röntgen upptäckte röntgenstrålar 1896 utvecklades den diagnostiska röntgentekniken snabbt. Under första hälften av 1900-talet var användningen av joniserande strålning i form av röntgenstrålar den enda princip med vilken den allt mer tekniskt avancerade röntgendiagnostiken bedrevs. För att åskådliggöra blodkärl använder sig konventionell r
Studies of natural radiative lifetimes and hyperfine structure have been performed for group IIA and IIIA atoms. Different laser spectroscopic techniques such as PUMOLS, time-resolved laser spectroscopy, using transient recorder, and collimated atomic-beam experiments have been used. These methods employ cw or pulsed dye laser systems. The lifetime measurements revealed several cases in barium and
Reviews and practice guidelines for paediatric obsessive-compulsive disorder (OCD) recommend cognitive-behaviour therapy (CBT) as the psychological treatment of choice, but note that it has not been sufficiently evaluated for children and adolescents and that more randomized controlled trials are needed. The aim of this trial was to evaluate effectiveness and optimal delivery of CBT, emphasizing c
Simulation and computer-aided analysis of complex mechanical systems has become a task of increasing importance in computational mechanics. It requires software tools combining modeling support, efficient generation of the equations of motion as well as modern numerical solution and system analysis techniques.
The research described in this thesis has an interdisciplinary approach dealing with chemical, biological, and technical issues. One objective was to interface miniaturized liquid chromatography (LC) to mass spectrometry, i.e. MALDI-TOF MS and ESI-MS, in an unattended mode for high sensitivity determination of proteins and peptides. The coupling between capillary LC and MALDI was accomplished by e
