This thesis evaluated the performance of the water balance model BROOK90 for an even aged spruce forest in southern Sweden. The water balance of the forest was modelled from 1950 onwards to find periods and patterns of drought. Moreover, the impact of climate change as well as thinning as a strategy to reduce drought stress on the water balance were evaluated. Hyltemossa, a managed Norway spruce f

Inom vattenhantering och rening används olika processer och teknologier för att säkerställa att vatten är säkert att konsumera och att avloppsvatten hanteras på ett miljövänligt sätt. För att kontrollera dessa processer och säkerställa ett stabilt flöde och en säker process används olika automatiserade system. Dessa automationssystem kontrollerar allt från olika flöden genom pumpar och ventiler, t

För en framgångsrik ”grön omställning”, med ett samhälle och industri som går i samklang med klimatet och miljön, behövs nya tillvägagångssätt, prioriteringar och verktyg. Det blir mer och mer självklart för företag och organisationer att sätta upp mål och arbeta strategiskt för att minska sin klimatpåverkan. Men i ny EU lagstiftning ingår det även att ta hänsyn till biologisk mångfald. Den snabbaThis study presents a systematic overview and mapping of potential metrics for evaluating the impact of forest management on biodiversity in Swedish forestry. The primary approach involves quantitative Life Cycle Impact Assessments (LCIA) as part of Life Cycle Assessments (LCA). Given the increasing need to integrate the impact on biodiversity into complex value chains, the absence of a standardis

Challenges connected to unsustainable practices are becoming more prominent in society and higher education can aid in promoting sustainability. Swedish universities are since 2006 regulated by law to integrate sustainability into their practices, therefore, this thesis uses qualitative analysis to investigate if the law has promoted integration of sustainable development in the syllabi of a Swedi

The 2008 financial crisis exposed significant weaknesses within the global financial system which were mostly attributed to the practices of financialization. This thesis explores the potential of Islamic finance principles to prevent financial crises while offering a more stable and equitable financial framework. A qualitative approach was used in order to conduct interviews with various professi

Acne vulgaris is a widespread skin disease affecting approximately 9.4 % of the population. It arises from four primary factors: increased sebum production, hyperkeratinization, bacterial colonization, and inflammation, leading to both non-inflammatory and inflammatory lesions. Current treatments include topical and systemic anti-inflammatory agents, antibiotics, and retinols, which often have adv

This master's thesis, in collaboration with Comsys AB, examines the optimal size of a Battery Energy Storage System (BESS) for two services - energy shifting and constant power delivery across the four price areas SE1, SE2, SE3, and SE4 in Sweden. For energy shifting applications, the optimal storage capacities were found to be 20 MWh (2 MWh/MW) in SE1, SE2, and SE4. However, a 0.5 MWh/MW stor

PFAS är en grupp av 10 000 människoskapade ämnen, kända för sina fett-, smuts- och vattenavstötande egenskaper, som använts sedan 1950-talet. De användes i bland annat brandskum, textiler och kosmetika. PFAS är mycket svårnedbrutna, de ansamlas i naturen och människor från intag av vatten, växter och djur. Det har visats att PFAS är vara farligt, PFAS kan negativt påverka reproduktions-, och hormoThis study focuses on PFAS-pollution, specifically the pollution situation for four objects in Svedala municipality. Per- and Polyfluorinated Chemicals (PFAS) has been used widely since the 1950s and spread because of anthropogenic activities, due to their characteristics, such as dirt-, grease, and water repellent properties in cosmetics, textiles and fire extinguishers. PFAS has shown to be pers

This thesis examines an unconventional issue of human trafficking, which has arisen very recently in the Southeast Asia region. An increasing number of scam centres have been identified, wherein trafficking victims were recruited to operate online fraudulent schemes. This emerging trafficking phenomenon exhibits distinctive characteristics compared to the traditional one, including the flow of mig

The construction industry generates a significant amount of waste and serious environmental impacts. Denmark has an ambitious climate goal to stay within the 1.5-2.0-degree target and transition to a circular economy. However, transitioning away from the well-accepted linear take-make-waste model triggers uncertainty and risk among stakeholders across the value chain within the supply chain for bu

This paper will examine the role the three most prominent Swedish actors of Försvarsmakten, SIDA and SCA had. This will be done by conducting a case study and examining the data that exists regarding the impact of the projects undertaken. This data takes the form of reports and evaluations discussing their respective involvement and contains information regarding the issues they faced. The data al

The jet breakup and the potential occurrence of satellite droplets play a crucial role in the print quality of drop-on-demand (DOD) systems. This thesis focuses on developing a numerical model to simulate droplet formation utilizing the volume-of-fluid (VOF) method. A particular focus is on the occurrence of satellite droplets and how different fluid properties influence the jetting behaviour. The

The electricity demand in Sweden is expected to double between 2022 and 2035 and the majority of the new electricity is expected to come from wind energy. As intermittent energy increases, so does the need for energy storage that can balance the supply and demand for energy. Batteries can offer short-term energy storage and their fast response time enables them to offer ancillary services on shor

Det sker en global energiomställning till förnybara energikällor för att minska koldioxidutsläppen och bekämpa klimatförändringar. I Sverige är det tydligt att andelen vind- och solkraft ökat de senaste åren och denna trend förväntas fortsätta parallellt med det ökade elbehovet. En utmaning med vind- och solkraft är dess intermittenta elproduktion med stora effektvariationer som elnätet behöver klRenewable energy projects are essential for a sustainable energy transition. In addition to the fundamental benefits of renewable power generation, such as climate change mitigation and clean air, renewable power projects with energy storage solutions can provide economic benefits for electricity producers and add value to the operation of the national grid. This thesis investigates the innovative
