This master thesis study presents the results of sediment transport analysis along Viskan, located in south Sweden. The main processes cover building a hydrodynamic model, studying parameters that define sediment transport, modelling sediment transport within the river, mapping out erosive stretches and comparing to observed eroded locations, and finally comparison of different transport functions
As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes. Greywater, which makes up about 80% of household water con
Previous studies have found what is referred to as a dilution effect of nondiagnostic information when subjects make evaluative judgment tasks of future performance, meaning that the presence of nondiagnostic information makes predictions less extreme. However, a large study recently failed to replicate this effect. The hypothesis of this study is that judges can discard from obviously irrelevant
Simulation mimics the behaviour of real world processes or the system over time. It helps us to understand the impact of modification and the effect of introducing various interventions to a system. One such simulation method is known as Monte Carlo (MC) simulation, which has been utilized to evaluate the performance of digital communication systems over the last 70 years. MC has been the most ex
Today, it is difficult to take care of organs that could have been donated to patients. In Sweden around 92 000 people die every year yet less than 200 of them become kidney donors. UGLK Science AB has developed a patented technology for restoring kidney function which increases the time window for donations significantly. In this project, the exterior of the kidney perfusion machine used for this
Sweden was once known for its open and generous refugee reception, with a mindset that was different from its neighbouring countries. However, this has changed in recent years. Due to an increased influx of people seeking asylum in Sweden, restrictive measures were put in place. The political discourse on migration shifted from a welcoming narrative to enforcing border controls and limiting access
Processed food is a big contribution to the increasing intake of salt among the population, which today is the double of the recommendation stated by the World Health Organization. This high intake of salt affects the human health in such a way that it can increase blood pressure, which in turn can lead to cardiovascular diseases, which are already the main cause of death cause among the world’s p
Det finns behov av en standardiserad metod över hur en produktions- och kvalitetskontroll i framställande av ballast och betong. För att tillgängligt råmaterial ska kunna användas på ett effektivt och hållbart sätt i betongframställning framgent krävs det tydligare metoder och kravställningar på betongproducenter. Det finns otydligheter i hur myndigheter och miljöcertifieringsorgan uttrycker sig g
Datortomografi perfusion är en kompletterande undersökningsmetod vid rädda hjärnan larm. DT perfusion framställer kartor som baseras på flera faktorer, såsom time to peak (TTP), cerebral blood volume (CBV) och cerebral blood flow (CBF). Syftet med studien var att belysa det diagnostiska värdet av DT perfusion av hjärnan vid misstanke om ischemi/infarkt. En litteraturstudie utfördes med integrerad
The average Swede uses 140 liters of water everyday. This combined with the usage in industry means that Swedish municipal water treatment plants produce approximately 900 billion liters of clean and safe drinking water every year. This does not include the fact that all water flowing to a treatment plant needs to be treated before being sent back out into the environment. These facts hint at what
Vehicle-to-everything (V2X) is a promising power storage solution for the challenges succeeding the Swedish renewable energy transition. Although, it is a niche innovation facing obstacles such as inadequate infrastructure, uncertainties of battery degradation and a lack of appropriate standards, which hinders its development. This thesis explores the business case for V2X for X Shore’s electric b
The primary purpose of this study is to examine how the market contributes in creating the ethical consumption gap to serve the underlying structures in which predicates and benefits from the gap. Consequently, the research seeks to add to current theoretical understanding in the field. The study draws on an ontological relativism position, accompanied by a social constructionist view. Moreover, t
The goal of this thesis was to explore the conversion of a propeller driven two-seater combustion airplane to an electrical airplane. Four different wing designs were considered. Two variations of Blackwing Sweden AB’s current Blackwing wing (BW), a longer wing (BW-L) and a shorter wing (BW-S), as well as a new wing with a different airfoil (GW). Using Computational Fluid Dynamics the wings were m
The relationship between inequality and conflict has been widely studied in the literature, finding non-significant results. However, the availability of new statistical software and geographical databases has boosted new literature on the topic, focusing on the regional level. Mozambique is now suffering a wave of conflicts whose causes seem varied. Using a negative-inflated binomial regression a
Bakgrund: Vid operationer i bäckenet finns det en risk för att sexualiteten blir påverkad. Utifrån kvinnans tidigare erfarenheter, normer och kultur kan synen på sexualitet te sig olika vilket ställer krav på sjuksköterskans roll i att bemöta kvinnan i de sexuella frågorna. Syfte: Denna rapport syftar till att belysa kvinnors upplevelse av sexualitet efter icke-malign hysterektomi. Metod: Litt
Background Dietary intervention is an effective way to prevent pandemic non-communicable diseases such as obesity and type 2 diabetes which can probably raise the risk of depression and Alzheimer's disease. Although considerable numbers of intervention studies focus on metabolic effects and physiological benefits of the intake of plant lipids, the function in appetite, mood, and cognition modu
As people develop different identities throughout their lifespan, unparalleled challenges such as climate change and COVID-19 and the great tendency to adapt to more sustainable life have encouraged them to opt for types of identities that are more suitable to overcome such challenges. Identities based on purchasing products and services for self-consumption have become less attractive, an inactiv
A lot of time and care have been put into exploring and explaining the power relations between nurses and nursing assistants, the emotional investment appropriate in care work, different views on leisure time for staff in this context (Warming, 2019; Habel, 2021; Jervis, 2002; Crocker, 2019). Less work has been done in exploring the complex relationships care workers have with their patients and h
Studiens syfte var att undersöka det gröna gapet mellan konsumenternas attityd och beteende när det kommer till köp av kläder. Resultatet visade att ett gap förekommer mellan konsumenters attityd och beteende när det kommer till köp av mer hållbara klädesplagg. Med andra ord, attityden skiljer sig från deras faktiska köpbeteende. Dessutom undersöktes vilka faktorer som hindrar konsumenter från grö
In this thesis, pp collisions were simulated using PYTHIA. D+ D- and D0 D0bar balance functions were created in order to contribute with a reference point for future balance functions measured in real data from Pb-Pb collisions. Charm balance functions are important since the charm quark can act as a probe of the QGP, probing the first instances after a collision. The balance functions were create
