Populärvetenskaplig beskrivning: Att veta hur olika saker i världen kom till hjälper en att släcka den törstiga sömn-förstörande nyfikenheten. Många har ställt sig frågan: hur skapades universum? Någorlunda hela svar har lagts fram (som till exempel teorin om Big Bang), men det finns mer att upptäcka. På en relativt mindre skala kan man fråga sig hur skapades Vintergatan? Ännu en fråga delvis svaradThe properties of the early Milky Way are quite mysterious and some are completely unknown even today. This study is the first one ever to analyze the mass distribution of Population III bulge stars. Using the fitting code STARFIT, we perform an analysis of 65 bulge metal-poor stars obtained by the EMBLA survey to estimate the IMF (initial mass function) of the very first stars that defined our ga

An estimated 6% of human greenhouse gas emissions are the result of enteric methane production by cows. Asparagopsis taxiformis, a semi-tropical alga, is one solution. Supplementation of this alga to cows at a small percentage of their daily intake has reduced methane emissions by over 98% in trials. This success has led to multiple commercialization attempts globally, although no Asparagopsis tax

Homework is widely used in most schools across the world to complement classroom teaching, increase knowledge retention, and foster good study habits. The research on the effect of homework assignment on student achievement is, however, inconclusive with earlier research indicating a positive relationship and newer studies giving a more nuanced picture. This thesis uses data from the 2019 wave of

The purpose of this study is to investigate how women with an ADHD diagnosis, who were diagnosed in the ages between 12-17, see their own experiences and identities in relation to role expectations of females. The ambition is to bring light to the stories of women, who have been in the shadow of the stereotypical ADHD man in society as well as in studies. The method chosen for empirical material i

Predictive archaeological modelling is a complex analytical process that requires the understanding of how complex environmental and anthropogenic spatial phenomena relate to the selection of archaeological site location and knowledge of the requirements and potential biases inherent in the method of modelling and the raw data itself. This paper aims to demonstrate the utility of the weights of ev

Mental illness has increasingly become a problem throughout the world and is believed to cost the global economy $16 trillion by 2030. Consequently, a growing body of literature investigates the possible causes of mental illness and more specifically, possible early life circumstances which may affect adult mental health. Limited research exists though in terms of exposure to recessions in utero a

Climate change is affecting all regions of the globe, causing a shift of temperature distributions. As species try to track their optimal thermal conditions, they are also potentially met with new photic environments. Photoperiod is the main cue for synchronizing migratory birds' circannual rhythms, affecting both their physiology and migration. Thus, their ability to incorporate and adjust to

Climate change is an issue affecting societies worldwide. As temperatures, precipitation patterns, and sea levels change, our buildings and properties are in danger. Therefore, it is crucial for real estate companies to adapt their properties to the effects of climate change as they will be impacted. To help companies make environmentally sustainable economic activities, the European Union has imp

High-grade serous ovarian cancer (HGSOC) is the most lethal subtype of ovarian cancer and remains a major clinical challenge due to frequent late diagnosis and limited treatment options. This study investigates the therapeutic potential of targeting the oncogenic interaction between metadherin (MTDH) and staphylococcal nuclease domain-containing 1 (SND1) which are proteins known to promote tumor p

Abstract Title: Social services department’s modern centaurs – about social worker's dual role in cases of suspected crimes contribution Authors: Branislav Ros; Carl-Johan Martinsson Tutor: Lena Palvén Examiner: Elizabeth Martinell Barfoed The purpose of this study was to examine how social workers, in the social services department of economical aid, experience their dual role as helper

Popular science summary Identifying an African Paradise Flycatcher using molecular techniques Five species of Paradise Flycatchers (Terpsiphone) occur in mainland Africa. Colour polymorphism and hybridization in these birds make species identification and defining species boundaries challenging. A melanistic individual was captured in Gashaka-Gumti National Park in Nigeria, and could not be iden

The now Swedish province of Scania has had a long history of violence and unrest, with several wars being fought on Scanian soil. Such tumultuous times must have impacted the common people and their living conditions, yet bioarchaeological research is lacking for post-medieval Scania and much of Sweden. By analysing a skeletal material from a 16-18th century semi-urban cemetery in Ängelholm, for w

Helicobacter pylori is an important pathogen inhabiting the human stomach. H. pylori binds plasminogen, a 90 kDa glycoprotein secreted by liver cells, and utilizes it for enhancing virulence. Surface receptors on the bacteria recognize plasminogen that is then activated into plasmin by host factors. The active plasmin can degrade a range of host proteins including proteins of the extracellular mat

Aims: Several studies have shown that self-rated health (SRH ) is associated with drug use. The aim of this study was to investigate the possible interaction between SRH and use of analgesics and hypnotics and its ability to predict disability pension. Methods: In 1974-78, complete birth-year cohorts of middle-aged male residents in Malmö, Sweden, were invited to a health screening, and the cohort

Background: The thorough assessment of familial prostate cancer (PCa) risk is as important as ever to provide a basis for clinical counselling and screening recommendations. Objective: Our aim was to determine the age-specific risks of PCa and the risk of death from PCa according to the number and the age of affected first-degree relatives. Design, setting, and participants: The nationwide Swedish

Objective To determine whether environmental control using nocturnal temperature controlled laminar airflow (TLA) treatment could improve the quality of life of patients with persistent atopic asthma. Design Randomised, double-blind, placebo-controlled, parallel-group trial. Setting Nineteen European asthma clinics. Participants 312 patients aged 7-70 with inadequately controlled persistent atopic

Objectives: To determine whether among middle-aged and elderly men there is evidence of international differences in the prevalence of chronic widespread pain (CWP) and whether any such differences could be explained by psychological, psychosocial factors or differences in physical health status. Methods: The European Male Ageing Study (EMAS) sampled from population registers in cities ( centres)
