An Organic Chemistry Odyssey : Imaging Mass Spectrometry in Neurotherapeutics, Asymmetric Methodology Development and Natural Product Synthesis
Första delen i denna avhandling fokuserar på 'Imaging Mass Spectrometry' (IMS), en analytisk teknik med kartografiska egenskaper. Denna teknik används dock inte för att kartlägga geografiska terränger, utan för att skapa kartor över det kemiska landskapet i biologiska prover, från vävnadssnitt av organ eller tumörer till enskilda celler. Dessa kartor visar med hög precision var olika molekyler, såThe development of imaging technologies and brain models is crucial for advancements in neurotherapeutic drug discovery and development. They assume a critical role in evaluating essential parameters such as drug blood-brain barrier (BBB) permeation, distribution, and metabolism, all of which are vital for the development of safe and effective medications. In the first part of this thesis, we expl

This article examines how work plays a major role in Danish Greenland literature – often with the workplace as a zone of conflict. At first, a literary historical presentation introduces the tradition followed by an analysis of Jørgen Liljensøe’s novel Barakkerne (1977). Lastly, newer Danish Greenland literature by Kim Leine and Iben Mondrup are discussed. The approach is primarily place-theoretic

Nymaterialistisk analyse af Kaspar Colling Nielsens værker Mount København (2010), Den danske borgerkrig 2018-24 (2013) og Det europæiske forår (2017). Værkerne læses som en trilogi med fokus på økokritik, det posthumane og kropsmaterialisme, og vi spørger: Hvad er et menneske, hvad er teknologi - og hvad sker der, når alt flyder sammen?
Surviving the Storm: Navigating the Quadruple Whammy Impact on Europe's Food Supply Chain
This article explores the impact of the ‘Quadruple Whammy’ consisting of Brexit, COVID-19, Conflicts (Russia-Ukraine and Israel-Palestine), and Natural disasters on the food supply chain in Europe. This research adopted a two-phase methodology comprised of e-Delphi technique followed by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approach within the context of t
Forehead flap perfusion monitored by laser speckle contrast imaging – importance of flap length and thickness
Purpose: Forehead flaps are commonly used in oculoplastic surgery to cover defects after tumor excision. Blood perfusion is vital for flap survival. The aim of this study was to monitor the perfusion in forehead flaps and investigate the impact of flap length and thickness. Methods: Nineteen forehead flaps in patients undergoing direct brow lift were studied. Perfusion was monitored using laser sp
The role of ice in planet formation
När stjärnor bildas omges de av en skiva bestående av gas, stoft och is. Detta är den protoplanetära skivan där de fasta beståndsdelarna växer från mikrometerstora dammpartiklar till planeter. Små stoftpartiklar kan växa genom kollisioner, men att nå tillräckliga partikelstorlekar och tillräckligt hög partikelkoncentration är utmanande. I denna avhandling undersöker jag om den så kallade islinjen As stars form, they are surrounded by a disc composed of gas, dust and ice – the protoplanetary disc, where solids grow from micrometre-sized dust to planets. Small dust grows readily by collisions. However, it is challenging to reach high enough particle sizes and dust-to-gas-ratios for continued growth to planetesimals – kilometre-sized and larger planetary building blocks. In this thesis I expl
Home ranges, directionality and the influence of moon phases on the movement ecology of Indian flying fox males in southern India
Flying foxes of the genus Pteropus are amongst the largest fruit bats and potential long-range pollinators and seed dispersers in the paleotropics. Pteropus giganteus (currently P. medius) is the only flying fox that is distributed throughout the Indian mainland, including in urban and rural areas. Using GPS telemetry, we mapped the home ranges and examined flight patterns in P. giganteus males ac
A phylogenetic framework of Palaearctic and Indomalayan Limacodidae (Lepidoptera, Zygaenoidea) based on sequence capture data
The slug moth family Limacodidae is a cosmopolitan group of economic importance, but its higher level systematics remains poorly understood. Here, we present a robust, higher level phylogenetic framework for Palaearctic and Indomalayan members of the family using sequence capture data of 148 nuclear protein-coding and 13 mitochondrial markers from 145 samples of 126 species in 67 genera representi
Population dynamics of dominant dinoflagellate species in the North Sea : in situ growth rates, photosynthetic potential, and losses due to parasitism
In the North Sea, Tripos and Dinophysis are commonly occurring mixotrophic planktonic dinoflagellate genera. In order to understand their bloom dynamics, an occurring bloom dominated by T. furca and D. norvegica was followed for several days. High cell abundances of these species were located to estimate: in situ growth rates from cell cycle analyses, depth distributions, growth rates sustained by
Landscapes of risk : A comparative analysis of landscape metrics for the ecotoxicological assessment of pesticide risk to bees
Pesticide use in agricultural landscapes creates environmental contamination that is heterogenous in space and time. Mobile organisms, such as bees, are exposed to multiple contamination sources when visiting patches that vary in the amount, timing and toxicity of pesticides used. Yet, environmental risk assessments (ERA) typically fail to consider this heterogeneity, in part because of the comple
Problem gaming in a clinical child and youth population - from prevalence data to evidence-based intervention
Introduktion: Dataspelande är en väldigt vanlig fritidssyssla och en majoritet av svenska ungdomar uppger att de spelar dataspel dagligen. En minoritet av dessa utvecklar ett problematiskt spelbeteende, ett fenomen som fått formellt erkännande i och med att diagnosen Gaming Disorder (GD) inkluderats i diagnossystemet ICD-11. Nu efterfrågar både barn- och ungdomspsykiatrin (BUP), skolhälsovården oc
Effect of silicone oil versus gas tamponade on macular layer microstructure after pars plana vitrectomy for macula on rhegmatogenous retinal detachment
Purpose: To analyze structural changes in the macular retinal layers and sub-foveal choroidal thickness (SFCT) in eyes after macula-on rhegmatogenous retinal detachment (RRD) repair by pars plana vitrectomy with either silicone oil (SO) or gas tamponade, and the effect of these changes on visual acuity. Patients and methods: Retrospective study which included 26 eyes in the SO Group and 32 in the
All that glitters is not gold : The depoliticization of social inequality in European education policy on ‘microcredentials’
At the present conjuncture of political, economic, social, and ecological crises, it is important to pay attention to the ways in which intensifying demands for equality, sustainability and social inclusion are met in education policy. In this article, we present results from a critical discourse analysis of an EU council recommendation on ‘microcredentials’ – credits for short courses primarily o
Enhanced LWIR response of InP/InAsP quantum discs-in-nanowire array photodetectors by photogating and ultra-thin ITO contacts
Here we report on an experimental and theoretical investigation of the long-wavelength infrared (LWIR) photoresponse of photodetectors based on arrays of three million InP nanowires with axially embedded InAsP quantum discs. An ultra-thin top indium tin oxide contact combined with a novel photogating mechanism facilitates an improved LWIR normal incidence sensitivity in contrast to traditional pla
Skewness and kurtosis of mean transverse momentum fluctuations at the LHC energies

Monitoring the Intracellular Fate of Molecular Beacons : The Challenge of False Positive Signals
Molecular beacons (MBs) have been used on surfaces for detecting oligonucleotides. Attempts to use them intracellularly for monitoring mRNA content have been made, however, without any clear conclusion regarding the reliability of the method, mainly due to false positive signals. To reach an understanding of the intracellular fate of MBs, a critical question remains: how long after MB delivery and
