Blue stragglers were first discovered as hotter and more luminous than the turnoff in the globular cluster M3. Their presence is typically explained by the interplay between stellar collisions and mass transfer in binary systems. In this thesis, I study blue stragglers produced from primordial binary evolution. This is done by both reproducing individual blue stragglers, to examine the different f

Tänk om du levde i en värld med ett stabilt klimat där fler företag bedrev sin verksamhet utefter cirkulära affärsmodeller. Ett samhälle som anammat mer hållbara konsumtionsbeteenden, skapat fler arbetstillfällen, och äntligen slutat utarma Jordens naturresurser. Vore inte det en härlig tillvaro? Vill vi förverkliga drömmen bör vi ställa oss frågan vad som krävs för att vi ska komma dit. Mer speciThe shortage of Earth’s limited resources is becoming more evident and our planet’s climate system is under immense pressure. To combat these problems, more people investigate the concept of circularity. This study intended to find out what make consumers motivated to buy used items from a professional refurbisher, thereby replacing purchases of brand-new products, and also identifying barriers.

The exposure to flooding in coastal Bangladesh is expected to increase throughout the century as a result of climate change-induced sea level rise and intensified monsoon precipitation. The current consequences of flooding include damage to infrastructure, economy, and health through inundation and saline intrusion, and are likely to affect a larger population in the future. Adequate flood modelli

The aim is to develop a product concept that can increase comfort while being transported in a practical way with a bicycl

Det har visats att svenska högskole- och universitetsstudenter mår psykiskt sämre i jämförelse med yrkesverksamma i samma ålder. Tidigare studier har visat att det finns ett samband mellan fysisk träning och bättre mental hälsa. Trots detta rör många på sig för lite. Denna studie undersökte hur regelbunden träning påverkar svenska studenters mående och vilka effekter den har på deras liv. Detta gjIt has been shown that university students in comparison to the working population of the same age are more exposed to factors that can lead to poor mental health. Previous studies have shown that there is a relationship between physical exercise and improved mental health. Despite this, many don’t get enough exercise. This study explored how frequent exercise affects Swedish university students&#

This bachelor project addresses the longevity of small electrical home appliances and how one through design can prolong the life of a product. During the project, multiple interviews were held with knowledgeable people regarding today’s electrical recycling and how to design for longevity, but information was also gathered through research publi- cations and a survey. By working with a desig

Använda immateriella rättigheter för att öka ett företags hållbara påverkan Immateriella rättigheter är verktyg för att stimulera innovation och investeringar i forskning och utveckling för att främja tillväxt och har traditionellt använts för ekonomiska intressen före miljömässig och social påverkan. Forskningsprojektet IPACST, som forskar på immateriella tillgångars roll för att accelerera en hIntellectual Property Rights, IPR, are tools to incentivize innovation and investment in Research and Development (R&D) to promote growth and are traditionally used for economic interests before environmental and social concerns. The research project IPACST has developed a business tool kit for supporting organizations in designing their IP models to increase environmental and social impact. T

The lack of women in leadership positions in the corporate sector is widespread throughout Europe. In this thesis, I study the efficacy of the Italian Gender Board Quota law no. 120/2011 in reducing such disparity in the Italian context. The impact of the policy is analysed with the innovative synthetic control methodology, which creates a no-policy scenario for Italy. By comparing the synthetic c

Cosmetic innovations are about finding high performing creative solutions that deliver into the consumer trends. The consumer trend within the cosmetic industry is currently driving a growing demand for more clean, natural skin care products with sustainable credentials. Enhanced delivery to and interaction with the skin can be achieved through knowledge-based design and characterization of delive

What upsets and outrages today’s neighbors in a quiet suburban area in Norway? This study aims to explore the social order of neighbor-Facebook groups through a thematic analysis of three Facebook-groups and 83 posts related to deviance. By looking at posts concerning everything from adolescents smoking marihuana to stolen potted plants this study finds that deviance, even today, draws people toge

Medling utförs världen över i olika sammanhang med målet att ge ett avslut på någon form av konflikt. Intresset till medling vid brott väcktes utifrån artikeln Victim Offender Mediation in Sweden: An Activity Falling Apart? av Jacobsson et al. (2018), där ett flertal problem med den svenska medlingen vid brott utifrån organisering, lagar och praxis lyfts. Med bakgrund i artikeln blev syftet med st

Composites like CFRP and GFRP have been a popular alternative in several industries such as aerospace, automotive, energy, marine and consumer goods. However, these materials being non-recyclable, bio-composite materials are being investigated to explore areas where it can replace the conventional composites. One such alternative is Flax-Polylactic acid(PLA)-based bio-composite which is 100 % recy

In camera production the image quality is of utter importance. Several tests during the production ensure this high quality. In this thesis the possibility of creating a final test, that classifies the image quality with the help of machine learning, specifically convolutional neural networks, was investigated. The data used was made up of synthetic, simulated images with commonly observed quality

The study of minimal surfaces has a long history, due to the important applications. Given a fixed boundary, one wants to minimise the surface area: this can be used, for example, to minimise the area of the roof of a building. Similarly, looking for constant mean curvature (CMC) provides us with many interesting ap- plications in physics – one of the easiest examples are soap bubbles. In this wor

I takt med att antalet geoparker och tillgängliga geologiska besöksmål ökar föds ett behov av att förstå hur dessa kan användas för att öka den geologiska kunskapen i samhället. Ett av syftena med geoparker är att främja utbildning om hållbar utveckling och bevarande av både geologiska arv och Jorden. De senaste åren har tre svenska geoparker certifierats nationellt eller internationellt och ytterAs the number of geoparks and available geological tourist destinations increases there is also a need to understand how these can be used to increase geological knowledge in society. One of the purposes of geoparks is to promote education about sustainable use and protection of both geological heritages and Earth itself. In recent years in Sweden, three geoparks have been nationally or internatio

The hypothesis for the study was that perspective-taking has a positive correlation with both creativity and psychological flexibility, that empathetic concern has a positive correlation with creativity and psychological fle

Denna studie tar avstamp i barn och ungas ökade klimatångest och den ojämlika ansvarsfördelningen som råder mellan barn- och vuxnas miljöengagemang i nutida barnlitteratur, där barnen oftast görs till de huvudsakliga agenterna. Studiens syfte är att undersöka vuxenvärldens miljöengagemang i ett antal barnböcker med hållbarhetstema och därigenom spåra de samhälleliga föreställningar som kan ses li

Mycket är känt gällande kopplingar mellan boendemiljöer och psykisk hälsa, men hur det ser ut i en svensk kontext är inte lika utforskat. Högskole- och universitetsstudenter har visat sig vara en sårbar grupp gällande psykisk hälsa, och COVID-19 pandemin har ytterligare belyst behovet av att utforska hur det relaterar till boendemiljöer då studenter spenderat mer tid än tidigare i sina hem. SåledeMuch is known regarding the connections between residential environments and mental health, but less so in a Swedish context. Students in higher education have been found to be a vulnerable group in terms of mental health problems, and the COVID-19 pandemic has further emphasised the need to explore how mental health relates to residential environments, as students have spent more time in their ho

Patents have long been considered an essential intellectual property mechanism in Japan. Foreign firms have simultaneously struggled with obtaining patents and market shares in Japan. Therefore, the incentives for Swedish innovating firms to patent their innovation at the Japanese Patent Office are plenty and can facilitate market integration. This thesis explores the historical development of Swe
