Tänk dig att vegetationen till ett närliggande naturområde var helt täckt av rödbruna rostlager. Faktum är att befolkningen i Kristianstad fick bevittna detta längs med strandängarna intill Helge å efter stora översvämningar under sommaren 2007. Metallutfällningarna som huvudsakligen bestod av järn och aluminium påverkar omkringliggande natur och djurliv negativt. Frågan är vart föroreningarna kLeakage of iron and aluminium from acid sulphate soils has received more and more recognition in Sweden during recent years. Research show that key drivers for this release of metals is lowered groundwater levels and aeration of sulphide soils which turns the soils into acidic sulphate soils. This can cause exstensive degradation of the surrounding environment which has been observed downstrea

I många aerodynamiska höghastighets-applikationer som t.ex. raketmotorer och vindtunnlar används ett så kallat konvergerande-divergerande munstycke, vilket är en rörformad del där tvärsnittsarean först minskar och sedan ökar. Sådana munstycken används ofta för att accelerera luft till supersoniska hastigheter, vilket innebär att det flödar snabbare än ljudets hastighet som är ungefär 343 m/s. Vid This thesis investigates the potential of using Fourier neural operators to predict subsonic and supersonic flows in converging-diverging nozzles, which includes complex flow phenomena such as shock waves. Two different data sets were generated using the Euler equations for fluid flow, one based on analytical relations for a quasi one-dimensional nozzle and another one which was created by numeric

This study investigates how EPU affects stock returns and volatility for Sweden’s four largest banks: Swedbank, Skandinaviska Enskilda Banken, Svenska Handelsbanken, and Nordea. As a small open economy with a concentrated and globally exposed banking sector, Sweden is particularly vulnerable to both domestic and international uncertainty shocks. Using monthly data from 2000 to 2024, we apply a GAR

The climate crisis will continue to threaten coastal cities. The mitigation method of building seawalls along the coast is often seen as an effective remedy for recurring floods. However, this infrastructure can have severe impacts on communities that rely on fishing and aquaculture. There need to be alternatives to the usual urban planning and design methods, which often overlook less fortunate

Kan klimatförändringar göra Sverige till ett vinland? I Skåne har vinodlingen vuxit kraftigt under de senaste decennierna. Denna studie undersöker hur vinodlare i regionen ser på klimatets roll i utvecklingen – och hur de planerar för en framtid som blir allt mer osäker. Att vin produceras i Skåne är ett relativt nytt fenomen. För några decennier sedan ansågs klimatet vara för kallt och instabiltAs climate change reshapes agricultural possibilities across Europe, new crops are emerging in previously marginal regions. In Skåne, southern Sweden, commercial wine production has expanded in recent years. This study explores how local winegrowers perceive the role of climate change in this development, what climate-related risks and opportunities they foresee, and what strategies they adopt to

The customer group analyzed consists of houses in southern Sweden, SE4, equipped with both solar electricity production (PV) and electric vehicles (EVs) with home charging st

Byggbranschen står inför en digital transformation där teknologier som digitala tvillingar, artificiell intelligens och internet of things börjar implementeras allt mer idag. Genom att skapa en digital modell som kontinuerligt uppdateras med realtidsdata och kopplas samman med fysiska byggnader, möjliggörs det övervakning, analysering och optimering av byggnadens prestanda. Syftet med studien haThe construction industry is undergoing a digital transformation, where technologies such as digital twins, artificial intelligence (AI), and Internet of Things (IoT) are increasingly being implemented. By creating a digital model that is continuously updated with real-time data and connected to a physical building, it becomes possible to monitor, analyse and optimize building performance. The pu

This study aimed to examine and analyze how social workers perceive the new Social Service Act and its ambition to reduce individual needs evaluations. The new Social Service Act also includes increased access to receive social support without social workers’ decision-making. The study aims to generate an understanding of social workers' experiences regarding their professional practice relate

As issues regarding social security and gang violence have risen, safety has become a central concern, both internationally and in Sweden. Several strategies have been developed to counter the possibility of committing crime by changing the urban design and use of public space, including in socio-economically disadvantaged areas. One approach that has emerged from this is Crime Prevention Through

This thesis seeks to bring new understanding in the handling of comics and how the implicit views of librarians can affect this. It further attempts to discuss the pros and cons in different shelving solutions as well as act as a guide to librarians seeking to organize their comics section. The questions that was asked were: How do libraries choose to present their comics in the physical room? How

This thesis applies deep learning methods to examine the forecastability of green bond yields relative to conventional (brown) bond yields. Using Transformer-based neural networks trained on a large panel of macro-financial indicators, selected via LASSO regularization, we develop forecasting models that differentiate between regular and crisis periods. The results suggest that green and brown bon
