By applying one of the largest datasets on ESG ratings to date with around 8000 companies included during the sample period between 2006-2021. This paper investigates the increasingly popular link between firms’ social and financial performance and the potential abnormal returns to be found using ESG investment strategies. To examine this relationship, a series of portfolios are constructed based
This master thesis project has been done within the Mechanics department of Lunds Tekniska Högskola (LTH). It studies the nanometric cutting process of a single crystal copper workpiece by a cubic diamond tool using Molecular Dynamics (MD) simulations on the software LAMMPS. Several simulations are computed in order to study the influence of different factors. In a first place, several tool model
Nominal rigidity is a central question in the debates to address better models to predict the outcome of certain policies. However, there is little empirical evidence that gives a deeper understanding of the mechanism that transmits this friction into the economy. This paper aims to understand the relationship between price rigidity and wage rigidity in the Swedish economy. I found a positive rela
This text is an attempt to re-evaluate the significance of Roman imports in Scandinavian contexts as well as to answer overarching questions concerning frontier zones, and the building of core-periphery relationships. This is achieved by applying the Roman concepts of hospitium and dona militaria as well as theoretical frameworks such as provincial ritual practices and cultural hybridisation to a
Many theorists have argued that vision and geometry have been given too much precedence within architecture and architectural representation. This thesis uses feminist theory that criticizes the way that space and the future traditionally have been represented. It discusses how the tools that architects use to describe space and future, can affect the how they think. The starting point for the dis
"The Moon is not made of cheese!": A history of ideas thesis on Georg Borgström and the space research This thesis discusses and analysis Georg Borgström’s arguments against the space research program in the 1960s. It begins with his appearance in the Swedish radio on the 28 of August 1960 with the title “Mat eller månraketer” (“Food or moon rockets”). It then stretches throughout the 6
The emergence of the Faster-Than-Nyquist signaling (FTN) technology has im- proved the tight spectrum resources by compressing the transmission interval between adjacent pulses. In a natural environment, data transmission via a wire- less medium and through multi-path, at a high data rate, the leakage of these paths among symbols can cause severe inter-symbol interference (ISI). In order to compen
Planet earth is getting hotter and regional climates are becoming increasingly unpredictable across the globe. Cities and communities on all continents are already impacted by the changing climate, but also by two other crises – the fossil-energy decent and the 6th mass extinction event. These three complex and interconnected crises all increase the risk of food becoming a scarce resource. In fact
In this project, a regioselective method to deprotect and acylate the amide on C5 of sialic acid is explored. Sialic acid is one of the most complex monosaccharides and is an important ligand in many higher organisms in intercellular cell communication. The most prominent example is related to the immune system. Sialic acids are attached as the terminal carbohydrate on cell surface glycans, which
Drygt 20 % av Sveriges befolkning har egen brunn, antingen i sin fasta bostad eller i sitt fritidshus. Det är därför viktigt att detta vatten hanteras på ett hållbart sätt, både före och efter användning för att inte orsaka skada på miljön eller befolkningen i framtiden. De flesta med egen brunn har någon form av dricksvattenrening. Vilken typ av rening beror på vilka ämnen som förekommer i vattne
Transposable elements (TEs) are mobile genetic elements that make up roughly 50% of the human genome, with retrotransposons (or transposons which retrotranspose via an RNA intermediate) making up the vast majority of these elements. Recent studies have suggested that TEs could play a role in many neurological conditions, including ALS and dementia. The specific reasons why TEs are associated with
One of the main challenges in ecology and evolutionary biology is to understand how biodiversity emerges and is maintained, given the complexity of ecological and evolutionary processes combined. Understanding how multi-trophic interactions occur from a theoretical perspective is highly relevant for our understanding of diversification in complex ecosystems. Here, I explore how the diversification
The genetic causes of familial breast cancer are still unclear, where only less than 20% have evident germline mutations. Most studies focus on mutations that cause a direct impact in the protein, disregarding the synonymous variants, where the codon is changed but the amino acid encoded remains the same. Synonymous variants can affect mRNA stability and translation, by differences in codon usage
As important components of the ecological system on earth, microorganisms and plants collectively constitute an assemblage of species called the holobionts. Microorganisms play an important role in the growth, development, and immunity of plants. Microorganisms may act as pathogens of plants, but they may also contribute to plant growth and development as well as help plants to tolerate both bioti
Motivation: Proteomics is the large-scale study of all the proteins found in a cell, tissue or organism. In the last few years, and thanks to the development of mass spectrometry and bioinformatics, proteomics has led the research in several fields, ranging from medicine to agriculture. In order to reconstruct the amino acid sequence de novo protein sequencing can be used. It uses the protein’s mo
In an extensive analysis of seven coastal sites that are spread across the East and West coast of southern Sweden, animal economy and specialised hunting is at the forefront of interpreting the subsistence strategy and mobility in Mesolithic hunter-gatherer societies. Through comparative data, the following thesis will observe the differences and similarities between the aforementioned coastal reg
Past material categorisation and preference in archaeological research are often heavily influenced by modern material perception, through the use of modern language and modern terminological connotations. This thesis seeks to clarify material categorisation and preference in the past, by studying two different skeuomorphs; Aurignacian shell skeuomorphs made from ivory, and south Scandinavian meta
Enligt senaste IPCC-rapporten står världen inför ett stort klimatproblem. Flera organisationer arbetar aktivt på en global och nationell nivå för att bromsa in klimatförändringarna. Strävan mot klimatneutralitet är redan idag högst relevant inom byggnadssektorn för att nå målet om ett klimatneutralt samhälle år 2045. Syftet med examensarbetet är att undersöka möjligheten att bygga till ett klima
Numerous location-based services (LBS) have evolved because of the fast development of mobile Internet for use in commerce, entertainment, security, and other areas. All of these need a precise real-time location-based service with smooth indoor- outdoor transition in highly populated areas. A truly omnipresent location system for both indoor and outdoor settings is still not accessible, despite t
