During this thesis nanoporous alumina has been used as a template for the synthesis of nano-confined palladium structures. The nanoporous templates have been synthesized by anodization of aluminum and characterized using atomic force microscopy (AFM), scanning electron microscopy (SEM) and small angle X-ray scattering (SAXS), resulting in good statistics of the pore diameter and interpore distance
Biomedical application of nanoparticles is largely associated to their fate in biological media which, in fact, is related to their surface properties. Surface functionalitzation plays a key role in determining biodegradation, cytotoxicity and biodistribution through interactions which may be meditated by the macromolecules occurring in biological media. This project is focused on the effect of di
In an age of increasing usage of heavily interconnected platforms, graph databases have increased in popularity due to their ease of modelling these systems. This thesis will evaluate if the graph database Neo4j can be used to model Lime's CRM System efficiently by comparing the performance of Neo4j and MS SQL on queries similar to those existing in Lime CRM. To benchmark the databases, they w
This research aims to investigate the relation of CEO compensation, especially how the sensitivity of CEO wealth to stock return volatility (vega), but also how the sensitivity of CEO wealth to stock price (delta) affects the risk of the firm. Moreover, these relations are investigated in the context of cross-listing to examine whether there are differences between US-only listed firms and those t
Modication of wood is carried out to increase the durability and dimensional stability of wood, and one of the modication methods is acetylation. Acetylation of wood means that polymers in the cell wall react with acetic anhydride. Today, acetylated wood is rarely used in load-bearing structures and there are only a few studies on how the fracture characteristics are affected by acetylation. A stu
Detta project utfördes i samarbete med svenska förpackningsföretaget Tetra Pak Packaging Solutions AB. Deras huvuduppgift är att utveckla förpacknngsmaterial, processer och maskinlinjer som krävs för att producera laminatet, vilket är att flerskiktsmaterial som vanligtvis består av papper, plast och aluminium för att skapa en stark och skyddande barriär för flytande livsmedel. För att skapa laminaThis project was carried out in cooperation with Swedish packaging company Tetra Pak Packaging Solutions AB. Their main purpose is to develop the packaging material, process, and machine lines needed to produce the laminate, which is a multi-layered material typically made by combining paper, plastic, and aluminum to create a strong, protective barrier for liquid food packaging. In order to create
Problem: The Milky Way disk consists of two distinct components, the thin and thick disk, each with unique kinematical, elemental, and age-related properties. Among all the properties considered, age stands out as the only one that does not exhibit significant overlap, thereby offering clearer separation between the populations. Stellar ages, determined through isochrone fitting, are reliable main
Extremophilic bacteria, like Rhodothermus marinus, hold promising potential to be used as non-model cell factories for the production of various metabolites, such as carotenoids or exopolysaccharides, due to their inherent adaptability to extreme environmental conditions. This study explores the production, isolation, and characterisation of carotenoids from an engineered R. marinus strain termed
Quantum mechanical technologies often relies on the system being cooled to low temperatures. One way to achieve this is with measurement and feedback based cooling. In this thesis measurement and feedback on a quantum harmonic oscillator coupled to a thermal reservoir is considered. The Wiseman-Milburn equation is used with a linear feedback control to find the steady-state solutions for the first
The aim of this thesis is to investigate the mechanical response of paperboard in the out-of-plane direction by incorporating its microstructural characteristics, with a particular focus on fiber-fiber interactions and fracture mechanisms. These features are implemented into models of varying complexity to evaluate their influence on material behavior. Two fracture modeling techniques, the Extend
Carmilla (1872) is a foundational gothic novella that explores female intimacy, monstrosity, and transgression within a patriarchal context. While widely recognized for its depiction of same-sex desire and subversion of Victorian gender norms, the story also reveals a deeper network of violence that sustains social and gendered hierarchies. However, critical attention has often focused more on Car
NMDA receptors are ligand-gated ion channels assembled as heterotetramers composed of glycine-binding GluN1 and GluN3 subunits (GluN3A-B), and glutamate-binding GluN2 subunits (GluN2A-D). Their involvement in various psychiatric and neurological disorders makes them potential therapeutic targets. However, compared to the extensively studied GluN1/2 NMDARs, the functional, physiological, and pharma
This study investigated how acoustical challenges, specifically changes in signal-to-noise ratio (SNR), affect the neural tracking of attended and ignored speech in individuals with hearing impairment. The analysis began with the speech envelope and was progressively extended by incorporating phonetic information as well as outputs from all layers of OpenAI’s Whisper model. The goal was to gain a
Pythia with Rope Hadronization, and the Canonical-Statistical Model with strangeness undersaturation (γSCSM), have shown remarkably similar results when simulating strange hadrons yields relative to pion yields as a function of event-multiplicity. As the underlying assumptions in these models are very different, a novel observable is warranted. The aim of this thesis is to show that K0S/(π+ + π−)
Emerging storage devices, particularly ferroelectric tunnel junction (FTJ) memristors, offer a compelling solution for high-density storage as they form a type of non-charge based non-volatile storage capable of storing multiple bits in each device; however, their adoption is hindered by reliability concerns. This work addresses this by presenting a design and implementation of an efficient Error
Constipation and irregular bowel movements are a daily challenge in elderly care, especially among patients with dementia who struggle to report their own toilet habits. This thesis investigates the possibility of using millimeter-wave pulsed coherent radar to passively monitor toilet visits and estimate both stool consistency and excreted quantity of urine and feces. This involved constructing a
Power amplifiers play a crucial role in wireless communication systems. However, they can achieve high efficiency only when operating in the nonlinear region. To maintain linear output while operating in this region, several techniques have been developed, among which digital pre-distortion (DPD) is one of the most widely used. In this thesis, we designed and analyzed a digital predistortion (DPD)
Antimicrobial resistance (AMR) is a growing global health concern, driven by the overuse of antibiotics and a lack of new drug development. To address this challenge, alternative antibacterial targets involved in essential bacterial functions are being explored. In this study, three compounds were synthesized using N-acetylglucosamine as the starting material. One of these compounds serves as a ke
