Brinnande bilar, drunknande isbjörnar och träd som dör ut - det är detta som en del föreställer sig när det gäller global uppvärmning. För att förhindra att detta sker, behöver fossila bränslen ersättas i framtiden. En möjlighet är att använda biobränslen istället, fast problemet är att de innehåller mycket metan. Detta är tyvärr en farlig växthusgas som måste vidarebearbetas i förbränningsanläggnThe study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. This thesis contributes to the understanding of that reaction in a 5 mbar environmental pressure regime over a polycrystalli

With the growing global demand for affordable housing, the housing deficit needs to be addressed with building solutions that are fast to build while less expensive to operate and construct. As most prefabricated systems are targeted to mess production, individuality and option for customization has become highly limited. Looking into what is currently available in the market, reviewing these off

This master thesis project applies a mixed methods approach to fulfill the purpose of exploring how and in what ways digitalization transforms different retail categories. A theoretical framework is formulated using existing theories and research, from which four key variables are identified: distribution, interaction, competition and product offering. These variables, combined with an overarching

In the fall of 2022, Sweden's most significant social service that is located in Malmö City went through a major organizational change. The goal of the reorganization was that it would be easier to manage the daily operations, collaborate internally, and primarily handle cases equally when the respective departments were located in the same buildings. The aim of this study is to gain the persp

Both during and after the pandemic, the trend of biophilic design has reached maximum acceleration. One of the consequences being an increasing interest in gardening and plant care in general. Though not everybody might have so called ‘green fingers’, everyone should have the opportunity to try, and a product that facilitates horticulture is the self watering planter. IKEA of Sweden is looking int

Parkinson’s disease (PD) is a neurodegenerative disorder with toxic forms of alpha synuclein (α-syn) accumulating in the midbrain dopaminergic (DA) neurons, leading to cell death. In the first part of the study we wanted to investigate the midbrain DA population and their gene expression relative to the intracellular α-syn load. To this end, human wildtype α-syn was packaged inside custom, uniquel

Artificial Intelligence (AI) and Machine Learning (ML) have been increasingly attracting attentions in many different fields. Healthcare is one of the areas that has greatly benefited from the advances in AI/ML. This includes a wide range of applications such as medical data interpretation, disease or abnormality detection or prediction, monitoring specific health condition and medical data manage

Increasing the effectiveness and efficiency of production processes have always been a significant challenge, primarily because such processes often contain activities that lead to waste. In response to address these challenges, tools like Lean and Six Sigma, and over time their descendant, Lean Six Sigma (LSS) were developed. It is argued that Industry 4.0 proliferated data accessibility in the m

Stone tools define earlier prehistory but the extent of their usage in later periods remains uncertain, as the archaeological community tends to focus on trademark materials from respective time periods. Accordingly, usage of chipped stone such as quartz and flint in later periods, tends to be ignored or regarded as residual from earlier Stone age activities, resulting in that valuable knowled

This paper investigates the effects on inflation of the Quantitative Easing programme employed by the Swedish Riksbank during the years 2015-2019. As previous studies have presented contradicting results on the topic, this paper aims to evaluate the potential effect of asset purchases on inflation through some of the main transmission channels identified by prevailing literature, namely the exchan

This thesis report treats my individual project “The Filter”, a result from the Bachelor Studio Contemporary Architecture at the faculty of Engineering at Lund University. The report describes my design and concept process. I Investigated how to design a Filter that demonstrates the natural cleaning process, and how to design the other parts of the naturrum. The report displays how the design deci

The goal of this thesis is to answer the question: Will a special cash dividend announcement from a company on NASDAQ GS create abnormal returns? This thesis will therefore find and measure abnormal returns surrounding a special cash dividend announcement. This is done by performing an event study, following the market model, consisting of 96 announcements from companies listed on the Nasdaq GS. T

In this essay, I will examine what Origen of Alexandria believed about the resurrection of the body. Origen was condemned as a heretic at the Second Council of Constantinople in 553, one of the main reasons for this was that he was said to deny the physical resurrection of the body. Due to the condemnation of Origen, the work of copying his works was also stopped, with the result that many of Orig

Over recent decades, use of insecticides to protect plants from pests and harmful insects have increased manyfold. Neonicotinoid insecticides, such as Imidacloprid (IMI) acts as partial agonists on nicotinic acetylcholine receptors which are widely present in both the central and peripheral nervous system of insects. Pollinators like Eristalis tenax are frequently exposed to these pesticides but h

Background: Sweden has a long-standing tradition of youth-friendly services focusing on sexual, reproductive and mental health. Currently, they are mainly targeting and being used by girls and young women. Little is known about what motivates and prevents boys and young men from seeking out and utilising health services, including the youth clinics. This study therefore aimed to investigate factor

Detta arbete är en översättningsvetenskaplig analys som baseras på översättningen av ett utdrag ur Simon Winchesters Atlantic: A Vast Ocean of a Million Stories, utgiven 2010. Första delen utgörs av en inledning, där boken och författaren presenteras översiktligt. Andra delen består av en källtextanalys efter analysmodellen i Lennart Hellspong och Per Ledins Vägar genom texten (1997). Tredje delen

This thesis aims to understand copula theory and its application in measuring dependence, particularly in the context of the paper "Multivariate conditional versions of Spearman’s rho and related measures of tail dependence" by Schmid and Schmidt. We clarify certain statements and formulas in Schmid and Schmidt's work, explore the potential of the conditional version of Spearman'

We develop a deep learning model that uses financial news articles and historical exchange rates to predict the rate for the Euro/US Dollar currency pair one hour ahead. From the articles’ titles and bodies we extract sentiment scores using two different transformer based classifiers – one for short text and one for long text. The long-text classifier is built and trained by us. These sentiment sc

Breast cancer is the most frequently diagnosed form of cancer worldwide. 2 260 000 people were diagnosed with breast cancer year 2020, and 685 000 people deceased from it. In low income countries, breast cancer is commonly detected at a later stage when it is harder to treat, thus entailing a higher mortality rate. This is primarily due to the lack of knowledge and diagnostic tools available. A lo
