There is a need for tools that in a simple way can be used for the evaluation of image quality related to clinical requirements in mammography. The aim of this work was to adjust the present European image quality criteria to be relevant also for digital mammography images, and to use as simple and as few criteria as possible. A pilot evaluation of the new set of criteria was made with mammograms
Background. The procedure of human islet isolation needs further optimization and standardization. Here, we describe techniques to enhance enzymatic digestion and minimize mechanical forces during the digestion process. The isolation protocol has also been modified to meet current GMP (cGMP) standards. Moreover, the impact of donor- and process-related factors was correlated to the use of islets f
Abstract in UndeterminedThis report is a study of literature found in the field of energy use in single-family houses. It is to be regarded as a first phase, part of the project "Sustainable energy use in houses". The literature examined refers to, predominantly, Swedish conditions, including Swedish building technique and the Nordic climate. The objectives of the report are to present topics of i
The effect of thermal ionization on the growth of soot particles has been analyzed by detailed kinetic modeling of a low-pressure premixed acetylene flame. The detailed kinetic model considers the oxidation of fuel, the formation and growth of polycyclic aromatic hydrocarbons, and particle inception, coagulation, as well as mass growth via surface reactions. A numerical method has been developed,
Popular Abstract in Swedish En hjärtinfarkt, dvs död hjärtmuskel, uppstår då en del av hjärtats muskel inte blodförsörjs, exempelvis genom att en propp bildats i ett av hjärtats blodkärl. Detta tillstånd bör behandlas snarast möjligt för att rädda största möjliga del av hjärtmuskeln, eftersom en större infarkt innebär sämre pumpfunktion vilket ger patienten sämre prognos. Tidsförloppet för en hjärThe effect of duration of ischaemia on final infarct size is well established in animal studies, but not fully evaluated in humans. Delayed contrast-enhanced magnetic resonance imaging (DE-MRI) can be used to distinguish between viable and non-viable myocardium and thus to quantify infarct size. We therefore used DE-MRI to investigate how duration of ischaemia affects final infarct size normalized
In this study, a dilute mixture of volatile organic compounds in aqueous solution was separated by means of hydrophobic pervaporation, using three different poly(octylmethyl siloxane) membranes of various thicknesses. The permeabilities were determined for homologous series of compounds from the chemical groups of alcohols, esters, and aldehydes, and they were then related to some characteristic p
This is the fourth Research Seminar on Self-Desiccation in Concrete organized by the Building Materials Division of Lund University. The three previous seminars were held in 1997, 1999, and 2002.
Danish migration policy became extremely restrictive after the 2015 migration crisis, with the most striking measure being the amendment of the Aliens Act in June 2021. This law allows the Danish government to negotiate a deal with a third country to process asylum applications outside of Denmark. During the 1980s, migration policy in Europe was securitised, portraying migration as a threat to the
Den juridiska frågan om i vilken utsträckning stater får tvångsrädda människor på internationellt vatten, har fått ny betydelse i och med migrationsflödet över centrala Medelhavet. Flera incidenter har visat att det finns såväl strategiska som rent överlevnadsbaserade grunder till att migranter och flyktingar motsätter sig räddning av vissa statsfartyg på Medelhavet. Denna uppsats syftar till att The legal question of State’s use of forcible measures to rescue people on international water has gained relevance in relation to the current migratory movements on the Mediterranean Sea. Multiple incidents have shown that there are strategic as well as pure survival motives for a migrant boat to refuse assistance. The aim of this thesis is to investigate to what extent States may use forcible me
Climate adaptation policies in Nepal have previously depicted women as vulnerable victims. Policy-makers have described women as a weak and voiceless group that needs “saving” in environmental politics. Several studies have emphasized that these simplistic representations perpetuate gender stereotypes and omit proactive roles in climate action. Recent developments in feminist academia recognize th
The social, environmental, and economic impact of cars in urban areas are a rising concern of the public and policy makers since motorized vehicles have several negative impacts on individual health and climate change. Car free developments have induced positive changes in all three dimensions of sustainability. The development of car free cities, however, often encounters stakeholder adversity. T
The aim of this thesis is to develop, test and evaluate a penalized basis spline as a method for representing the Standard Model background in dijet searches from proton-proton collisions at the Large Hadron Collider. Current representations of the Standard Model background are complex and dependent on current assumptions of the Standard Model. Using a P-spline is interesting because of its simpli
This thesis is a comparative case study about how the Swedish municipalities Malmö and Umeå address gender aspects in their comprehensive plans. It also discusses how these municipalities approach the situation of women with diverse ethnic backgrounds in their planning strategies. According to previous research, immigrant women often have different experiences of the city than other women. The the

The intra-granular stress and strain evolution of 12 quasi-spherical silica grains, subject to uniaxial loading, has been investigated by analysis of scanning x-ray diffraction data collected at the ID11 ESRF synchrotron beamline. By applying the methods described by Henningsson et al. [1], the intra-granular strains were reconstructed and converted into stresses using an anisotropic linear-elasti
We want to have a good life! In fact, this is the core of urbanism and the reason why we keep building and constantly improving our cities. The ideal of how we wanted to live has changed through the time and developed into a form many people are satisfied with. But there is so much behind us living this ‘good life’. The urgency of climate crisis and the worsening situation for humans in afflict
The fight against malaria in Kenya is tightly connected to gender inequalities. The traditional gender roles in some households create exposure patterns that affect the most vulnerable groups: pregnant women and children. Current political strategies to prevent malaria in pregnancy rely on community health volunteers (CHVs), who fulfil a crucial role as implementers of malaria policies on communit
In recent years, romantic love has been problematized and questioned by sociologists and activists. Part of this questioning comes from relationship anarchy, a phenomenon which can be described partly as a critical school of social philosophy, partly as a comparably small-sized social movement. Sociologists such as Beck and Beck-Gernsheim argue that romantic love suffers from a conflict between cl
