Stjärnströmmar är strömmar av stjärnor som har blivit ryckta ur antingen klotformiga stjärnhopar eller dvärggalaxer, som är i omloppsbana rund mer massiva galaxer. Forskare har hittat dessa stjärnströmmar runt vår galax Vintergatan. Exempelvis Sagittarius strömmen, som formas från dvärggalaxen Sagittarius, och Palomar 5 strömmen, som bildas av en klotformig stjärnhop. Strömmarna har också observerStellar streams are probes of the properties of their host potentials, giving clues about the host's shape, mass and substructure. There are several observed stellar streams both around the Milky Way and around external galaxies, and they are studied thoroughly. However, the impact of (i) the properties of the progenitor cluster or dwarf galaxy that form the streams, of (ii) the streams' o

The environmental and social impacts from the textile value chain have resulted in increased interest and involvement from various stakeholders, one of which being local government. As a means to address the negative impacts of the textile industry, circular economy theory has been adopted by many stakeholders, often using the term ‘circular fashion.’ A critical component of circular fashion is a

Arbetet problematiserar framför allt den klassiska sångarens utmaning i att gestalta roller inom andra genrers än opera. Med hjälp av källor i form av egna intervjuer och inspelade historiska Title: The snowman comes to life This lecture recital problematizes and explores my approach in Rusty Magees musical opera “Flurry tale”. The lecture recital primarily problematizes challenges for the classically trained singers performing roles outside of the opera genre. By the help of sources such as conducted interviews and historical recordings I present vocal approaches to performing in

Ammonia combustion in gas turbines is emerging as a carbon-free solution for the power-generation sector. The challenges associated with using ammonia as a fuel include its combustion characteristics, which can lead to instability, and the emission of NOx due to the presence of nitrogen atoms. This study examines the diffusion flames of partially cracked ammonia at low cracking degrees and the air

This study examines the relationship between the German yield curve and stock market performance in Germany, the Netherlands, and Switzerland by extending the Fama-French Five Factor Model with Carhart's Momentum factor and a yield curve factor. Three hypotheses are tested: the positive relationship between changes in the yield curve and excess stock returns, the lagged effect of yield curve c

The focus of this paper is linguistic imperialism and coloniality. This was researched by investigating the language attitudes of students and alumni in the language teacher programs and their professors at Lund University. The control group consisted of students at Lund University who had not studied language or linguistics. The research was conducted through a questionnaire and deeper interviews

Det första syftet är att analysera hur svenska börsnoterade företag följer upp förväntade synergieffekter vid företagsförvärv. Det andra syftet är att analysera företagens lärandeprocesser efter företagsförvärv. För att samla in

Ensuring close control of critical quality attributes (CQAs), such as post-translational modifications (PTMs), in therapeutic monoclonal antibodies (mAbs) is essential for maintaining function and batch homogeneity in large-scale production. Common PTMs include deamidation, fragmentation, oxidation, charge variants, and glycosylations. This study aimed to evaluate CQA variations and correlate the

The fight against climate change has reached a crossroads, necessitating critical assessment of the means designed to mitigate the ongoing crisis. This thesis examines the impact of the Market Stability Reserve (MSR) on installation-level emissions and emissions intensities in Norway. The MSR, introduced in 2019, was designed to address the surplus of emissions allowances in the EU Emissions Tradi

This thesis investigates the adoption of artificial intelligence (AI) solutions among architects in Sweden. Architects are currently experiencing headwinds and decreased demands for their services as increasing interest rates and a weak economy have contributed to a decline in construction activity. Simultaneously, advancements in AI have introduced a range of innovative technologies to the field

Vi testar om det går att bygga generaliserade modeller för tidsseriedata och om den framgångsrika AI-arkitekturen Transformer kan hjälpa oss med detta. Vår slutsats är att sådana modeller är möjliga, men att vi inte kan fastställa huruvida Transformer är värd mödan eller inte. Alla typer av mätningar i vilken utveckling över tid är av intresse kan porträtteras som tidsserier. Dessa är sekvenser aA reliable forward prediction of time series data is essential for optimising resource allocation, mitigating risks, and enhancing strategic decision-making across various domains. However, the limited historical data available can pose a challenge for accurate modelling. Conversely, transformer architectures, renowned for their success in natural language tasks through zero-shot inference, demons

A housewife of many trades: applying history of knowledge to the rationalization of the home in 1946–1956. After World War II, Swedish women were expected to return to their work at home, due to a shortfall of work for men. However, to make housework more attractive for women, its status needed to increase. One way to make housework more appealing for women was to rationalize the home and therefo

The purpose of this essay is to find out how the Swedish district court relates to children’s rights when sentencing young offenders to the new penalty called youth surveillance. Since the Convention on the Rights of the Child is a part of the Swedish law, there was an interest to examine whether law in books actually is implemented in law in action regarding the penalty of youth surveillance. T

Nya lagar och miljöcertifieringar införs idag för att minska byggindustrins miljö- och klimatpåverkan. Från och med 2022 har krav ställts på klimatdeklaration av nybyggnationer med en byggnadsarea större än 100 m2 för att kontrollera hur stor klimatpåverkan en byggnad har. Cementproduktionen står för en stor del av byggindustrins koldioxidutsläpp, vilket gör att byggindustrins koldioxidutsläppNew laws and environmental certifications are being introduced today to reduce the environmental impact of the construction industry. From 2022 onwards, environmental declarations have been required for new buildings with a construction area of more than 100 m2 in order to control the environmental impact of a building. Cement production accounts for a large proportion of carbon dioxide emissi

Technological development has empirically demonstrated significant social impact across diverse global contexts. The uncertainty of the effects necessitates continuously updated research and historical revision to foster sustainable processes and address research gaps. Traditional economic optimism tends to overlook multidimensional compositions of effects, beyond financial gains. This paper exami

Detta projekt riktar sig till att undersöka om vi kan skapa en bild av en simulerad galax, göra mätningar på den som om ett värkligt teleskop hade sett den på natthimlen, och se om dessa mätningar stämmer överens med simulerade mätvärden. Med hjälp av given data så kommer vi återskapa en bild med hög upplösning som om du själv stod framför och tittade på galaxen. Sedan kommer vi dumma ner bilden sThe angular momentum of a galaxy is a very important concept when studying its kinematics. The two parameters that define the angular momentum are the rotational velocity of the galaxy and its dynamical mass. One of the problems with measuring the rotational velocity of a galaxy is that the galaxy may be observed at an angle. This impacts the radial velocity profile a telescope will measure. It wo

In recent years, the focus that LGBTQ+ rights have been receiving internationally has led to the reconsideration of their status, in both national and international contexts. Among many examples, this shift has been significant in Israel, where political discourse has made LGBTQ+ rights more and more visible. This study aims to present the processes of how Israeli politicians have incorporated LGB

Tropical wetlands are considered to be the greatest source of wetland-associated methane emissions. Yet, their representation in bottom-up modelling approach is oversimplified in many cases, leading to low confidence in current and future attribution attempts. The LPJ-GUESS dynamic global ecosystem model (DGVM) combines a detailed representation of high-latitude peatlands with a primitive placehol
