Soil temperature fluctuations are typical at high latitudes in early spring or late autumn. Freeze-thaw cycles (FTCs) occur when the soil temperature fluctuates around 0°C, causing a change in the state of the soil solution. Due to climate change, FTCs are predicted to become more frequent and intense, especially in the Arctic, Antarctic, and cold temperate regions. In this study, two experiments

This study aims to investigate if inflexible investment agreements limit countries’ environmental ambition, mainly focusing on the potential existence of regulatory chill. A panel dataset of 54 countries covering the years from 2008 to 2023 is used to examine the relationship. The analysis employs a fixed effects regression model, initially applying the Environmental Kuznets Curve theoretical fram

Denna uppsats beskriver simuleringen av ett f¨ orpackningsmaterials mekaniska bete- ende under olika f¨ oruts¨ attningar. Specifikt har simuleringsmjukvaran COMSOL Mul- tiphysics anv¨ ants f¨ or att simulera stora deformationer av kartong och temperaturbe- roende delaminering mellan plastfilm och kartong.

The project was partitioned into three main parts. First, a quantitative assessment of COMSOL’s accuracy in modeling the large strain elastoplastic response of paperboard was con- ducted. Second, an evaluation was performed of COMSOL’s capability

Work-life balance är ett arbetsmiljöproblem som är av ökande relevans på både organisations- och individnivå. Ämnet är särskilt relevant för gymnasielärare, ett yrke som har sett en ökad grad av utbränning och långtidssjukskrivning under de senaste åren. Studien syftar till att analysera hur gymnasielärares fritid, arbete och work-life balance hänger samman och påverkar varandra och ifall det finnWork-life balance is a workplace issue that is increasing in relevance at both the organizational and individual levels. The topic is particularly relevant for high school teachers, a profession that has seen a rise in burnout and long-term sick leave in recent years. The study aims to analyze how high school teachers free time, work, and work-life balance are interconnected and influence each oth

The aim of this bachelor’s thesis is to examine whether, to what degree and in what pattern physical activity differed between medieval men of differing social status. An overall purpose of this was to test whether, and to what degree the purported warrior culture of the medieval nobility had on its manual physical activity. This was tested by examining the patterns of humeral midshaft bone geomet

Bakgrund: Personer med kognitiva funktionsnedsättningar behöver vardagligt stöd i större utsträckning än andra. När individer inom denna grupp antar den utmanande och krävande föräldrarollen saknas stöd som är utformat efter deras behov. Syfte: Med utgångspunkt i befintlig litteratur undersöker denna studie hur personer med kognitiv funktionsnedsättning upplever och hanterar sin vardag i relation Background: People with cognitive disabilities need everyday support to a greater extent than others. When individuals within this group take on the challenging and demanding parenting role, there is a lack of support that accommodates their needs. Aim: Based on existing literature, this study aims to examine how people with cognitive disabilities experience and manage their everyday life in r

Recently, there has been a noticeable increase in Swedish media coverage concerning criminal record checks. Trade union organizations in many sectors express concern about the growing application of such background checks during recruitment processes. Various actors, from individuals in the labor market to state institutions such as the Swedish Prison and Probation Service and the Public Employmen

För att bromsa utsläppen av växthusgaser behöver vi utveckla nya metoder för att generera, lagra och omvandla förnybar energi. Vätgas kan lagras i bränsleceller som vid förbränning enbart genererar vatten som biprodukt. Svårigheten med vätgas är att den behöver lagras och transporteras på ett säkert sätt då den är explosiv och väldigt reaktiv i gasform. Ett förslag är att man använder sig av molekThe environmental impact of mankind significantly affects the climate, where 2/3 of the CO2 emissions are generated by transportation. The green transition of fuels needs to happen fast, and finding alternative options to generate, store and transform energy is important. Hydrogen powered fuel cells can combust hydrogen to generate electricity, with only water as a byproduct. At ambient temperatur

Study purpose: This study explores how Floating Container Terminals (FCTs) located in the North and Baltic Seas can support the maritime shipping industry's growth while promoting sustainability. As freight transportation volumes rise and sustainability regulations tighten, ports face increasing demands to accommodate Ultra-Large Container Vessels (ULCVs) in an environmentally responsible mann

Denna kvalitativa studie syftar till att undersöka psykoterapeuters erfarenhet av existentiella frågor i behandling. Studien utforskar med hjälp av semistrukturerade intervjuer och tematisk analys hur deltagarna upplever att de existentiella villkoren döden, meningslöshet, ensamhet och frihet påverka patienterna Den undersöker även hur psykologer arbetar med dessa frågor i terapi samt vilken effekThis qualitative study aims to explore psychotherapists' experiences of existential concerns in treatment. Using semi-structured interviews and thematic analysis, the study examines how participants perceive the existential givens death, meaninglessness, isolation, and freedom to have influenced their clients. The study also investigates how psychologists address these themes in therapy and th

Tänk dig en typisk morgon, du vaknar och med en simpel blick låser du upp din telefon, din resväg planerar du med Google Maps och i bilen lyssnar du på musik som är noggrant utvald för just dig. Så länge det fungerar, behöver du inte fundera över hur det går till. Men vetenskapsmän nöjer sig inte med att det bara fungerar – de vill förstå. Denna rapport undersöker hur AI kan användas för att hittaThis study explores the relationships between voltage, temperature, and consumed life in silicon carbide (SiC) MOSFETs using symbolic regression as a data-driven tool for deriving interpretable equations. The data comes from an accelerated life-time test performed by RISE. The symbolic regression model was implemented using the open source program ”PySR”. Since real experimental data were used, cl

The rise of AI is leading to paradigm shifts in every sector of modern society, including the military. One concerning change is the increase in the development, testing, and deployment of autonomous weapons systems (AWS), which utilise modern AI without adequate controlling regulation or governance. This thesis explores what it means to have control of AWS and whether it is possible to effectivel

Datorsimuleringar av barnhjärtinterventioner Aortaklaffstenos är ett vanligt medfött hjärtfel hos barn, som innebär att aortaklaffen är trång och släpper igenom för lite blod. Aortaklaffen har vanligtvis tre klaffblad. I en typ av aortaklaffstenos har två av klaffbladen vuxit ihop, så att klaffen endast har två klaffblad. Detta leder till att klaffen inte kan öppnas helt vilket tvingar hjärtat atAortic valve stenosis is a common congenital heart defect among children. In affected patients, the normal tricuspid valve structure is malformed into a bicuspid valve structure due to a fusion at one commissure. A common treatment is transcatheter balloon valvuloplasty, where a balloon is inserted through the aortic valve and inflated to mechanically tear the fused region, restoring a tricuspid s

In this study the thermophilic marine bacterium Rhodothermus marinus DSM 16675 was exploited for the production of biosurfactants. Different strategies employing batch, or a combination of batch and fed-batch cultivations were investigated. These cultivations were performed both on complex and defined media. The extracted crude biosurfactants were then analyzed with different methods such as FTIR,
