PFAS are a group of persistent and harmful chemicals that are widely used in both industrial applications and consumer products. PFAS are commonly detected in the environment and pose health concerns. Adsorption by GAC is considered an effective treatment method for removing PFAS from water. After a certain period of operation, GAC requires high-temperature incineration as disposal method. Another
The purpose of this report is to investigate and compare two potato chip production lines to determine the optimal layout of the factories in order to maximize the chips' adhesion ability to seasoning. The hypothesis of this study is that the adhesive ability of chips is highly dependent on how warm they are when they are seasoned, with warmer chips having a stronger adhesive ability. This hy
To address global food security challenges caused by population growth and climate change, accurate prediction of crop yield is essential for sustainable agriculture. Winter wheat, a key global crop, faces production instability in regions like Sweden and Morocco due to extreme weather conditions. This study employed unmanned aerial vehicle (UAV)-based multispectral imagery and digital surface mod
Adaptive reuse of existing buildings as a part of the circular economy principle has become a more common approach to promote sustainable development, due to increasing urban densification and environmental concerns. Ventilation systems, as a major contributor to energy use in buildings, often face complete replacement during building reconstruction, despite their potential for extended service li
This Master's Thesis examines the possibility of developing a software tool for optimizing offshore wind power plant layouts in regards to wake effects. The study was conducted with the purpose of making development and operation of offshore wind power plants more efficient and cost effective. The tool, named OptiWind, was developed in Python and employs several imported packages for mathemati
Extrema klimathändelser, såsom betydande översvämningar, utgör en risk för naturkatastrofer. På grund av klimatförändringarnas effekter förväntas södra Sverige få fler betydande regnväder som kan orsaka översvämningar i allt högre grad med mängden utsläpp. I denna studie undersöks dagens och framtidens översvämningsrisk i ett litet område i denna region, inom Kävlinges avrinningsområde. I det framExtreme climate events, such as significant flooding, pose a natural disaster risk. Due to climate change effects, the southern region of Sweden is anticipated to receive more significant rainstorms that could cause flooding increasingly with the quantity of emissions. This study examines the present-day and future climate’s flooding risk in a small area in this region, within the Kävlinge Watersh
Conventional agriculture, dominated by annual crops, has revolutionised food production but also introduced significant environmental and social challenges. Perennial crops offer a promising alternative, with potential benefits for ecosystem services, agricultural sustainability, and food security. Although the environmental benefits of perennial crops, such as the intermediate wheat grass Kernza
The main focus of this case study was to assess ecological succession and restoration success after the removal of Rosa rugosa. Plant species composition and moss presence, bare ground cover, and biodiversity indices were analysed to identify patterns and differences within and between the restored and an invaded adjacent area. The complete absence of R. rugosa in restored plots confirms the effec
BACKGROUND: The risk of infection-related death is high in patients undergoing dialysis. This study aimed to identify the modifiable risk factors for PD-related infections in patients undergoing peritoneal dialysis.METHODS: This was a population-based retrospective cohort study conducted in Skåne, South Sweden, which included all patients receiving peritoneal dialysis (PD) between 2011 and 2020. T
Background: Diversion—patients who sell or share their medication—is a hotly debated but rela-tively unresearched phenomenon. We have investigated the prevalence of self-reported diversion ofmethadone and buprenorphine at OST programs in Sweden. We have also examined if demographic,treatment, and social factors can be associated with an increased risk of diversion. Methods: Structured interviews w
Background: Knowledge sharing within an organization is one of the main focuses of the knowledge management research field. In today’s globally dispersed business units, and multinational corporations (MNCs), information and communication technology (ICT) tools play an essential role in facilitating knowledge sharing. Previous research has argued the vital role informal contexts as well as physica
While renewable energy output in the World increases, Russia shows an opposite trend, consisting of a highly engrained fossil fuel-driven economy with very little State priority towards diversifying its energy supply. Accordingly, although wind energy represents only a niche market, it is more economically viable to electrifying Northern peripheral communities than connecting them to the national
The increasing demands on the vehicle market regarding cost effectiveness, efficient production and innovative solutions create an unforgiving environment for the suppliers. Haldex has developed Haldex Way, a management and improvement framework focused on lean production to meet these demands. Although lean methodologies are utilized at Haldex, Haldex Way has currently issues with consistency and
Populärvetenskaplig sammanfattning: Naturkatastrofer är något som Sverige är relativt förskonat från. Massrörelser, alltså markrörelser i jordtäcke eller berg såsom lerskred, slamströmmar och bergras, är däremot relativt vanligt förekommande runt om i landet. Det är dessutom så att frekvensen av den här typen av fenomen förväntas öka i Sverige till följd av framtida klimatförändringar. De områdenRecent studies indicate a widespread but largely overlooked hazard of contaminant mobilisation and transport in connection to mass movement activity into surface water systems in Sweden. Concerns are exacerbated by predicted effects of climate change, which suggest national increases in rates of precipitation, pore water pressures, run -off, erosion and mass movement occurrence. In this study, the
Uppsatsens huvudsakliga syfte är att utreda om det med härledning till EU-rätten och EUD:s rättspraxis kan utrönas en gränsdragning för när en privatperson till-handahåller tjänster kan anses göra detta i egenskap av en beskattningsbar person och följaktligen faller transaktionen under mervärdesskatterättens tillämpnings-område. Utredningens analytiska utgångspunkt utgår från det ekonomiska sam-liThis essay's main purpose is to examine when a private individual, who provides services, can be considered to do this as a taxable person and therefore falls under the scope of VAT. This survey's analytical starting point is based on the economic concept collaborative consumption. The term describes an economic model which is based on the coordination of individuals' consumption needs
The Maha Oya river mouth, located on the west coast of Sri Lanka, is seasonally closed by a sand bar formed at the river mouth due to little rainfall and thus little river discharge. A new Outlet, located just north of the Maha Oya river mouth, was created by the 2004 tsunami. The Outlet remains open all year because of its location in the lee of an offshore breakwater. When the Maha Oya river mou

55 m.ö.h. på Balsbergets södra sluttning finner man en av Sydsveriges största grottor, Balsbergsgrottan. Ungefär 250 meter vindlande gångar grenar sig ut från två större salar. Grottan har en rik historia, både ur ett geologiskt och ett funktionalistiskt perspektiv. De sedimentära bergarterna som bildades för 100 miljoner års sedan lade grunden till, att det efter förra istiden kunde bildas en gro55 meters above sea level on the southern slope of Balsberget you can find one of southern Sweden's largest caves, the Balsberg cave. Approximately 250 meters winding paths branch out from two large halls. The cave has a rich history, both from a geological and a functional perspective. The sedimentary rocks, formed 100 million years ago, laid the foundations for the advent of a cave here afte
