No full textImpact of image reconstruction on cerebral blood flow measured with 15O-water positron emission tomography
No full textBackground: 15O-water positron emission tomography (PET) is considered the gold standard method for non-invasive measurement of cerebral blood flow (CBF). However, previously published average CBF values in healthy subjects have varied greatly and the cause of these variations remains unclear. This study investigates how image reconstruction methods and spatial resolution affect CBF measurements with 15O-water PET. Methods: Eight healthy subjects each underwent dynamic 15O-water PET scans with continuous arterial blood sampling. Images were reconstructed using two different algorithms; ordered subset expectation maximisation and block sequential regularised expectation maximalisation with varying reconstruction parameters. CBF was estimated for the whole brain, grey matter, and central white matter. Reconstruction-specific effective spatial resolution was estimated using phantom measurements and simulations. Results: The mean whole brain CBF was 0.48 mL/cm3/min and showed little dependence on the image reconstruction method. Grey matter CBF varied between 0.52 and 0.57 mL/cm3/min, and central white matter CBF between 0.20 and 0.28 mL/cm3/min. Regional CBF showed great dependence on effective spatial resolution with a negative correlation between grey matter CBF and resolution (r = -0.96) and a positive correlation between central white matter and resolution (r = 0.93). Conclusion: This study concludes that grey matter and central white matter CBF, but not whole brain CBF measured with quantitative 15O-water PET is reconstruction method dependent, mainly due to varying spatial resolution with consequent partial volume effects. Variations in published CBF values cannot be explained solely by reconstruction methods or spatial resolution

No full textAtt spåra det förflutna : En analys av bosättningsmönster i östra Makedonien
No full textThis thesis examines long-term patterns of human settlement in Eastern Macedonia from the Neolithic to the Roman period. Using spatial analysis, it investigates how topographic factors, specifically slope, aspect and elevation, influenced where people chose to live. The study identifies broad preference for gentle slopes and south-facing terrain, while also noting shifts in elevation preference over time in both new and cumulative settlement data. These patterns are interpreted through a theoretical framework based on agency, entanglement and defensiveness to better understand the human and settlement choices present in within the study area.Denna avhandling undersöker långsiktiga mönster för mänsklig bosättning i östra Makedonien från neolitikum till romersk tid. Genom rumslig analys undersöks hur topografiska faktorer, specifikt lutning, aspekt och höjd, påverkade var människor valde att bosätta sig. Studien identifierar en bred preferens för svaga sluttningar och sydvända områden, samtidigt som den noterar förändring i höjdpreferenser över tid i både nya och kumulativa bosättningsdata. Dessa mönster tolkas genom ett teoretiskt ramverk baserat på agens, entanglement och försvarsbarhet för att bättre förstå de mänskliga val och bosättningsval som fanns inom studieområdet
Vindkraftsprojektet Storlandet - Ekokolonialism? : Ett arbete som undersöker krocken mellan vindkraftsutbyggnad och samisk renskötsel.
No full textDenna studie undersöker konflikten mellan den svenska statens satsningar på vindkraftsutbyggnad inom ramen för den gröna omställningen och de samiska urfolksrättigheterna, med fokus på projektet Storlandet i Gällivare kommun. Studien analyserar hur storskaliga miljöprojekt, som syftar till att främja fossilfri energiproduktion, kan komma i konflikt med traditionell samisk renskötsel och därmed riskera att reproducera koloniala maktstrukturer. Genom en kvalitativ dokumentanalys samt en fallstudie av vindkraftsprojektet Storlandet, appliceras begreppet ekokolonialism med hjälp av teorierna Green Sacrifice Zones (GSZ) och offerlogiker. Analysen tar hänsyn till både nationella lagar och internationella konventioner om urfolksrättigheter, särskilt FN:s deklaration om urfolks rättigheter. Studien visar hur projektet kan innebära betydande konsekvenser för samernas kulturella och ekonomiska rättigheter, samtidigt som det ifrågasätts i vilken utsträckning samernas rätt till självbestämmande och inflytande faktiskt respekteras. Om projektet genomförs, riskerar det att få allvarliga negativa konsekvenser för rennäringen i området och att inskränka urfolksrättigheter. Utbyggnaden kan därmed tolkas som en fortsättning på historiska mönster av maktobalans och exkludering av samiska perspektiv i beslut om markanvändning. Sammantaget visar analysen att ekokoloniala drag kan identifieras i fallet
Capital for green innovation: How public and private actors shape the future of fusion power in Sweden
No full textClimate change is regarded as one of the most immediate and severe challenges of our time, pushing a green transition in all sectors globally. At the same time, Sweden stands in front of rising energy needs while geopolitical conditions challenge energy independence. These conditions have created a promising opportunity for fusion power, a fossil-free solution capable of delivering large-scale, stable, and sustainable electricity. However, the commercialization of fusion power demands significant investments, while the deep tech field is characterized by long development timelines and high risk technologies. This thesis explores the funding of green hardware deep tech companies and its application on Swedish fusion power. Within green hardware deep tech, it identifies key motivations behind investors’ investments, maps the interplay between public- and private capital, and explores the opportunities and challenges in the funding landscape. The results show that investor’s and grant provider’s interests are driven by factors such as technological advancements and maturity, expected return, public sector support, and internal team qualities. Furthermore, this paper highlights a strong interdependence between public- and private funding of deep tech companies: public funding de-risks innovation for private investors, while private investment validates market potential for public actors. Lastly, the deep tech funding landscape faces regulatory and policy related bottlenecks and limited Swedish capital, but shows promising opportunities for deep tech that prove technological- and market advancements and secures energy sovereignty. The results underscore the need for a more coordinated investment ecosystem in Sweden, where public- and private actors work together to accelerate the commercialization of fusion power
Introduktion och tribusnyckel till svenska gallmyggor (Cecidomyiidae) i Micromyinae och Lestremiinae
No full textGall midges (Cecidomyiidae) are one of the most common animal groups in the world, and one of the least studied. Few people even know of their existence and even among entomologists only a handful of people have studied them. Maybe the least studied group within this understudied group are the mycophagous gall midges. We know very little of this group, even its basic ecology is uncertain. In this paper I am focusing on two early branches amongst the mycophagous gall midges: Lestremiinae and Micromyinae. I will summarize what is known about their ecology and phylogenetic relationships. With the help of DNA barcoding and morphological studies I have constructed a new key to sort out Lestremiinae and Micromyinae from other gall midges and a key to all tribes within the two subfamilies. The key is based on previous keys and modified with the goal of simplifying the identification process. An updated list of genera and number of species for Sweden and the world is included. With these new keys anyone should be able to identify mycophagous gall midges, something very few people today can do. This will enable more people to contribute to the field. During the study I also found a method that made it possible to morphologically study gall midges after DNA extraction, something that hasn’t been done previously. This will make it easier to combine morphological and molecular methods in the study of gall midges, something that is important for all organisms but crucial in a group this large and with small morphological differences between species.
Sustainabillity identity as an analytic tool for Engineering Education
No full textIdentity has been used as an analytic lens in engineering education for several years now [10] [13] [1] [4]. While there is growing research on how engineering identities are shaped focusing on engineers as problem-solvers [3] and innovators [11], relatively less attention has been given to how values such as sustainability are integrated into these identities. As global challenges such as climate change, resource depletion, and social inequities are rising [12], it is also imperative to ask how do engineering students see and feel about themselves in relation to these issues. The concept of a sustainability identity, how students see themselves, how others recognize them as such [4] [1], and how this identity influences their values, choices, and professional aspirations, in relation to sustainability remains relatively underexplored within the engineering education discourse [8]. Addressing and bridging this gap is crucial in preparing future engineers who are not only technically competent but also ethically and environmentally conscious [2]. The study centers engineering students’ meaning-making and lived experiences to understand how they develop, negotiate, and express their sustainability identities within different figured worlds [6] such as different disciplines, academic, social and personal spaces. It aims to develop a framework to understand sustainability identity formation in engineering students supporting informed integration of sustainability in curriculum design and educational practices
Rating of overall childbirth experience : A qualitative study of a quantitative measurement
No full text Introduction Overall childbirth experience scores are used both in research and in clinical settings. Since it is still not fully understood what assessment of childbirth experience on a single-item numeric rating scale or visual analog scale represents, the aim of this study was to explore women's reasoning and thoughts when rating overall childbirth experience numerically. Material and Methods A qualitative interview study of 26 women was conducted using a think-aloud technique at a university referral hospital in Sweden. A manifest qualitative content analysis was performed to generate categories and sub-categories representing how women decided which single value should represent their experience of giving birth. Results Two main categories emerged from the analysis. The first, Strategies for choosing a number, reflects variations in how the women approached the rating scale itself and includes five sub-categories, each relating to a different strategy: (1) Comparison, (2) Start from the maximum value, (3) Start from the middle, (4) Weigh certain experiences more heavily, and (5) A means to an end. The second category, Specific factors considered in the rating, includes four sub-categories, representing groups of factors contributing to the final childbirth experience score: (1) The time period, (2) Events linked to strong emotions, (3) Perceived support, and (4) Previous expectations. What the women included in their overall childbirth experience was hence translated into a number, using strategies from the first category and factors from the second category. Conclusions The considerable variations in how women approach the rating scale, and what they include in the assessment of overall childbirth experience, suggest that not only the childbirth experience itself but also the reasoning when evaluating it, is multifaceted. A standardized phrasing of the question and a clear purpose for the evaluation is warranted to strengthen the validity of the measurement. When used clinically for identifying women in need of support after childbirth, the rating should be followed by a conversation about the experience of giving birth, independent of the value chosen
