The background for this master thesis is the stricter emission control requirement in heavyduty diesel engines at the same time as the demands for improved diesel engine efficiency are getting stronger. One approach to meet these demands is to increase the fuel injector pressure. A higher fuel injector pressure makes the fuel spray more finely dispersed into the cylinder and a better combustion is
Authors: Johannes Nöbbelin and Peter Strandkvist. Title: Addiction & Interventions, the individual solutions. Supervisor: Helena Hansson Assessor: Carina Tigervall The aim with this study was to analyze and examine the factors underlying the social secretary's choice of treatment for addicts. In order to better understand the complexities in the choices social workers face when they invest
A theoretical study is presented, in which the nonlinear response of a bi-ased Quantum Cascade Laser (QCL) is calculated. The calculations are based on the nonequilibrium Green’s function formalism. Assuming a periodic electromagnetic field in the calculations, this formalism provides not only the stationary behavior Green’s functions, but also the part of the response that varies in time according
This master’s thesis examines the norm-critical awareness among children librarians in Swedish public libraries and how the practical everyday work with current literature for children function with this awareness. By adopting a norm-critical approach you have the ability to observe the different types of norms that you can find among us and that effects the way we see the world. Some of these nor
In England saltmarshes account for less than 0.5% of the land area, however they have a very high biodiversity value and provide significant economic and social worth. Climate change, continuous coastal urbanisation, and port development are a serious concern for coastal protection planners, city councils and the government. It is a challenge for these decision makers to balance the social, econom
Popular Abstract in Swedish Under 1990-talet har många kommunala verksamheter ställts inför ökade kostnader av äldre- och handikappomsorgen och flera organisatoriska förändringar har genomförts. Nya problem och dess lösningar beskrivs ofta förlagda till chef- och ledarskapsområdet. Chefer och ledare inom offentlig verksamhet har under de senaste åren tillskrivits en nästan magisk betydelse för verDuring the 1990s many of the local authorities have been forced to reduce expenditure on the care of the elderly and people with disabilities, and many organisational changes have been carried out. New problems and their solutions are often related to leadership and management. This dissertation deals with three trends in the development of the organisation: The first trend is a market orientation
Background. To evaluate the relationship between age and poor ovarian response to pregnancy and cancellation rate after IVF stimulation. Methods. Poor ovarian response was defined as <= 5 follicles at ovum pick up (OPU). Out of 1,706 consecutive OPUs performed during 2003/2004, 290 poor responders were identified. This cohort of poor responders was divided into two groups, 'older' and 'younger', w
□ Total hip arthroplasty (THA) registers are established in several countries to collect data aiming to improve the results after THA. Monitoring of adverse outcomes after THA has focused mainly on revision surgery, but patientreported outcomes have also been investigated. □ Several surgery-related factors influencing the survival of the THA have been thoroughly investigated and have changed clini
PURPOSE OF REVIEW: Experienced breathlessness and recalled breathlessness are two different entities, which may be associated with different factors and might have different impacts on function for the individual. The aim was to review the knowledge from the last 2 years concerning experienced breathlessness and recalled breathlessness and related factors. RECENT FINDINGS: Experienced breathlessne
Northeast China, the most important region for commercial grain farming in China, is vulnerable to drought due to high fluctuation in monthly rainfall. Timely, accurate and effective drought monitoring is very essential for securing the output of grain farming. In this study, three widely used drought indices were compared using satellite soil moisture data and their capability for drought monitor
Rationale: Cerebrovascular diseases associated with pregnancy and postpartum period are uncommon; however, they can have an important impact on health of both women and foetus or newborn. Aims: To evaluate the frequency, characteristics and management of cerebrovascular events in pregnant/postpartum women, to clarify pathophysiological mechanisms underlying the occurrence of these events including
Populärvetenskaplig sammanfattning2008 infördes en reform inom svensk politik för arbetskraftsmigration som möjliggjorde för personer utanför EU att komma till Sverige för att arbeta om de erbjudits anställning oavsett utbildningsbakgrund. Reformen har fått mycket uppmärksamhet och ritat om kartan för svensk migrationspolitik. Till ett av de mindre utforskade områdena hör s.k. spårbyten, det vill Many people believe that changes in Swedish migration politics in the last decade signal a turning point and perhaps the end of the well-reputed Swedish exceptionalism. In 2008, Swedish labour migration policy was transformed into one of the most open in whole OECD, whilst Swedish asylum migration policy, known for its humanitarianism, took a significant turn toward restrictiveness in 2016. For se
Peptide synthesis was carried out in a variety of organic solvents with low contents of water. The enzyme was deposited on the support material, celite, from an aqueous buffer solution. After evaporation of the water the biocatalyst was suspended in the reaction mixtures. The chymotrypsin-catalyzed reaction between Z-Phe-OMe and Leu-NH2 was used as a model reaction. Under the conditions used ([Z-P
Avhandlingen behandlar den socialistiska respektive den liberala internationella fredsrörelse som agerade under kvartsseklet före första världskrigets utbrott 1914.During the 25 years before the First World War in 1914 two different kinds of peace movements, one bourgeois-liberal and one socialist, were organised to fight militarism and war. The two movements – represented by the International Peace Bureau and the Second International, respectively – grew in size between 1889 and 1914. At the beginning of 1914, IPB organized over 200 peace associations, repr
Wooden multi-story buildings have increased their market share in Europe over the last decades, mainly due to their relatively small carbon footprint and rapid onsite construction. Compared to more conventional heavy concrete buildings, wooden buildings are more sensitive to dynamic loads at low frequencies. Moreover, the dynamic response is generally more difficult to predict. This is, for exampl
Aberrant stem cell-like gene regulatory networks are a feature of leukaemogenesis. The ETS-related gene (ERG), an important regulator of normal haematopoiesis, is also highly expressed in T-ALL and acute myeloid leukaemia (AML). However, the transcriptional regulation of ERG in leukaemic cells remains poorly understood. In order to discover transcriptional regulators of ERG, we employed a quantita
In this paper, we look at the terrain of Malcolm X's "failed rhetoric" as producing an apocalyptic refusal of world, and world making. This refusal finds its intensity from a distinct gnostic calculus, driving Malcolm X's political theology of names and worlds, seen in his oratory from the years 1962–1964. First, Malcolm X's nominal history is discussed in relation to the violence of naming and po
Background: The incidence of detected ductal carcinoma in situ (DCIS) continues to increase and now accounts for 14% of all breast cancer, and 20%–25% of screen-detected cases. Treatment trends of DCIS are important in order to inform the ongoing debate about possible overdiagnosis and overtreatment, but have not been investigated for over a decade in Australia and New Zealand. Against this backgr
Studies based on object-based image analysis (OBIA) representing the paradigm shift in remote sensing image change detection (CD) have achieved remarkable progress in the last decade. Their aim has been developing more intelligent interpretation analysis methods in the future. The prediction effect and performance stability of random forest (RF), as a new kind of machine learning algorithm, are be
In a previous study, in order to investigate the effect of charge stratification on combustion behavior such as combustion efficiency and combustion phasing which also largely affects the emissions, an experiment was conducted in a heavy-duty compression ignition (CI) metal engine. The engine behavior and emission characteristics were studied in the transition from HCCI mode to PPC mode by varying
