Syftet med studien är att beskriva hur vegetationen utvecklats på platsen sedan den senaste deglaciationen och även föreslå tidsperioder som skall illust

När en kosmisk kollision mellan jorden och en annan himlakropp sker, då bildas det nya bergarter. En av dessa bergarter är den omdebatterade pseudotachylitiska breccian (PTB). Bergarten PTB består av en snabbt avkyld smälta, med inneslutna rundade fragment från omgivande litologi. PTB har kristalliserats i djupa sprickor bildade vid nedslag, de varierar i storlek från mikrometer till hundratals meWhen a cosmic collision occurs between earth and another celestial body, new rock types are formed. One of these rock types is the controversial pseudotachylitic breccia PTB. The PTB consists of a rapidly cooled melt, with enveloped rounded fragments from the surrounding lithologi. The PTB has crystallized in deep cracks formed during impact, varying in size from micrometers to hundreds of meters

This study aimed to examine how professionals understand and talk about sex in exchange for compensation, with a particular focus on how the boundary between voluntariness and vulnerability was described. The study was based on qualitative semi-structured interviews with professionals who encounter individuals with experience of selling sex. The analysis was conducted using Gayle Rubin’s theory of

Elbehovet ökar och landbaserad solkraft lyfts fram som en lösning för att snabbt möta elektrifieringen, men när solparker planeras på jordbruksmark väcks debatten: mat eller el? En möjlig väg framåt är att upprätta solparker på lågproduktiv jordbruksmark och förvalta den som gräsmark för att främja kolinlagring. I den planerade solparken Kogshult, i Sjöbo kommun, undersöker denna studie solsambrukAs pressure on land-use increase due to climate change and a transition to fossil-free energy sources, there is a growing interest in the potential to combine agricultural activities with ground-mounted solar energy parks. While claiming agricultural land for energy production sparks a lot of debate, a potential compromise may lie in utilizing depleted agricultural land for solar farms, purposely

The findings of this study address a significant gap in the sustainable entrepreneurship literature by exploring the psychological drive

Denna studie undersöker hur svenska företag i ett tidigt skede tolkar AI Act i relation till GDPR:s princip om dataminimering. Genom en kvalitativ ansats med intervjuer identifieras en utbredd osäkerhet kring tolkningen och implementeringen av AI Act:s krav, särskilt i kombination med GDPR:s etablerade regelverk. AI Act:s riskbaserade struktur ställer nya krav på datastyrning, transparens och dokuThis study explores how Swedish companies, in an early phase, interpret the AI Act in relation to the GDPR’s principle of data minimization. Through a qualitative approach based on interviews, the study identifies widespread uncertainty surrounding the interpretation and implementation of the AI Act’s requirements, particularly in combination with the established framework of the GDPR. The AI Act’

Sverige står inför en betydande utmaning i att minska sina utsläpp av växthusgaser för att nå det nationella klimatmålet om nettnollutsläpp till år 2045. För bygg- och anläggningssektorn innebär detta en omfattande omställning, där alla aktörer i branschen aktivt behöver bidra för att målet ska kunna uppnås. I dagsläget är sektorn en av de större källorna till Sveriges koldioxidutsläpp vilket inneSweden faces a significant challenge in reducing its greenhouse gas emissions in order to reach the national climate goal of net-zero carbon emissions by 2045. For the construction sector, this requires a major transformation where all actors must actively contribute for the goal to be achieved. Currently, the sector is one of the largest contributors to Sweden’s carbon dioxide emissions, making m

Organic micropollutants comprise a diverse set of molecules, varying both with regard to the frequency of their use, as well as the potential harm they can inflict upon aquatic ecosystems. Ozonation has been recognized as an efficient method for their abatement, due to its ability to selectively oxidize molecular groups commonly found on organic molecules. Micropollutants are, however, rarely degr

Framtidsångest är bland studenter ett bestående samt växande problem som har en betydande påverkan på dels den mentala hälsan men även den akademiska framgången. Hur den hanteras och motverkas skiljer sig således beroende på olika faktorer, denna studie kommer att belysa vilken roll self-efficacy, locus of control (intern/extern) och problem- samt emotionsfokuserad coping spelar i detta. Metoden sFuture anxiety is an existing and continuous issue that has a significant impact on the mental health and academic success among university students. How it is handled and counteracted thus differs depending on various factors such as self-efficacy, locus of control (internal/external), emotion focused and problem focused coping, which are highlighted in this study. The method used to investigate

Uppsatsen avser att undersöka hur egna märkesvaror (EMV) påverkar vinstmarginaler i svensk dagligvaruhandel och vad det betyder för konkurrensläget, konsumenterna samt vilka som bär ansvaret för utvecklingen. Utredningen utfördes i tre steg. För det första analyseras dagligvaruhandelns struktur för att avgöra om marknaden kan klassas som ett oligopol. För det andra genomförs en ekonometrisk analysThis thesis investigates how own-label brands affect profit margins in the Swedish grocery retail sector – and what this implies for market competition, consumer outcomes, and the distribution of responsibility for current developments. The analysis is carried out in three parts. First, the market structure is examined to determine whether the sector can be classified as an oligopoly. Second, an e
