A tight correlation between the baryonic and observed acceleration of galaxies has been reported over a wide mass range (108 < M bar/M⊙ < 1011 M⊙); this is known as the radial acceleration relation (RAR). This has been interpreted as evidence that dark matter is actually a manifestation of a modified, weak-field gravity theory. In this work, we studied the radially resolved RAR of 12 nearby dwarf
The l’Hort de la Boquera site is located in the northeastern part of Iberia and its stone tool assemblage includes up to 25,000 flint artefacts. This is the first approach to the analysis of the raw material through an archaeopetrological study. Results were obtained by use of mineralogical techniques: macroscopic and petrographic analysis, Scanning Electronic Microscopy (SEM), Micro-Raman and X-R
In today’s world, the growing use of solar photovoltaic (PV) systems especially in the logistics sector has provided companies with new opportunities to produce renewable energy, improve their sustainability performance, and reduce carbon emissions from their operations. Importantly, the deployment of solar systems also helps contribute to broader environmental goals such as the European Green Dea
Green spaces are important parts of our cities supporting both public health and providing ecosystem services such as lowering air temperature and providing stress relief. The study area, Malmö is a city in southern Sweden with a high population density. The city is largely built on and surrounded by agricultural land resulting in few naturally occurring green spaces and only planted trees. Despit
Forskningsfrågor: Är tidigare studiers förklaringsmodeller för fastighetsföretags kapitalstruktur applicerbara på den svenska marknaden? Hur påverkar kapitalstrukturen hos svenska fastighetsbolag deras lönsamhet över en period av ränteförändringar? Syfte: Studiens syfte är att undersöka om de förklaringsmodeller för fastighetsföretags kapitalstruktur som presenteras i tidigare studier även kan appResearch questions: Are previous studies’ explanatory models for real estate companies’ capital structure applicable on the Swedish market? How does the capital structure of Swedish real estate companies affect their profitability over a period of interest rate chnages? Purpose: The purpose of this study is to examine whether the explanatory models for the capital structure of real estate companie
Genome-wide association studies (GWAS) have identified more than 50,000 SNP-trait associations. Most of these SNPs or genetic variants map to noncoding regions, known as or gene desserts. This makes it challenging to describe the mechanism by which the variant confers susceptibility to the trait. Increasingly, there is an interest in characterization and interpretation of the effect of non-coding
Seagrass meadows are a vital part of the marine ecosystem surrounding the island of Mallorca, but human-induced pressures are degrading the seagrass meadows’ stock of natural capital. Although researchers are working together with policymakers to implement and improve conservation measures, the current legal framework is not sufficient to protect the meadows from further depletion. Therefore, I us
This thesis focuses on both street art and outdoor advertisements in Istanbul. Specifically, we chose Istiklal and Bağdat Avenues as our fieldwork areas to conduct our research. With its cosmopolitan structure Istiklal Avenue and high-standard lifestyle Bağdat Avenue together represent Istanbul to understand the multifaceted nature of social, cultural and political identities of the society. In re
Syftet med den här licentiatuppsatsen är att ur ett universell utformningsperspektiv undersöka vad som kännetecknar dagens återvinningsmiljöer i kommunala bostadsområden och vilka värden som finns kopplade till dessa. De två frågeställningarna är: Vilka normer är framträdande i urvalet återvinningsmiljöer och hur bidrar utformningen till upplevelsen av inkluderande återvinningsmiljöer? Den första
Individual monitoring of radiation workers is essential to ensure compliance with legal dose limits and to ensure that doses are As Low As Reasonably Achievable. However, large uncertainties still exist in personal dosimetry and there are issues with compliance and incorrect wearing of dosimeters. The objective of the PODIUM (Personal Online Dosimetry Using Computational Methods) project was to im
In this work, the forestry-enabled dynamic vegetation model LPJ-GUESS was used to simulate forest standing volume for the three main regions of Sweden. At the regional scale, the model results were evaluated against observational data from the Swedish National Forest Inventory. Carbon fluxes of net ecosystem exchange (NEE), gross primary productivity (GPP), and ecosystem respiration (Reco) were si
Background: A neuroinflammatory response that may lead to edema and secondary brain damage is elicited in severe traumatic brain injury (TBI). Previous studies using microdialysis (MD) membranes with 100 k Dalton (kDa) cut-off found a transient intracerebral release of cytokines and chemokines without significant correlations to clinical course, intracranial pressure (ICP) or metabolites. In this
Canon and oblivion. The memorials of archaeology The Sun-Chariot from Trundholm is world famous, and the finding place is marked with a monument. In the same way the finding places for The golden horns from Gallehus, the Egtved girl, the Dejbjerg chariots, the Gundestrup cauldron, the Nydam boat and many other finds have been remembered during the 20th Century with memorials, often a stone monum
Melatonin is a powerful antioxidant and a synchronizer of many physiological processes. Alteration in melatonin signaling has been reported in a broad range of diseases, but little is known about the genetic variability of this pathway in humans. Here, we sequenced all the genes of the melatonin pathway -AA-NAT, ASMT, MTNR1A, MTNR1B and GPR50 - in 321 individuals from Sweden including 101 patients
Genome-wide association studies (GWASs) may help to understand the effects of genetic polymorphisms on breast cancer (BC) progression and survival. However, they give only a focused view, which cannot capture the tremendous complexity of this disease. Therefore, we investigated data from a previously conducted GWAS on BC survival for enriched pathways by different enrichment analysis tools using t
Hexokinase 2 (Hxk2p) from Saccharomyces cerevisiae is a bi-functional enzyme being both a catalyst and an important regulator in the glucose repression signal. In the presence of xylose Hxk2p is irreversibly inactivated through an autophosphorylation mechanism, affecting all functions. Consequently, the regulation of genes involved in sugar transport and fermentative metabolism is impaired. The ai
The large-scale migration of birds has been studied extensively by recoveries of ringed birds. However, there is very little ringing data from the arctic breeding grounds of waders. Here, the migration pattern of the dunlin, Calidris alpina, is studied with population genetic markers, using haplotype frequencies to estimate the breeding origin of migrating and wintering populations. Polymerase cha
