Mycobacterium avium complex (MAC) infections are still prevalent in humans, more prominent in immunocompromised individuals. These environmental mycobacteria are widely distributed in soil and water sources, making their exposure very common. In various organisms, phase variation enables reversible switches between avirulent and virulent states. Some strains of M. avium exhibit this visible phase
This report presents an innovative approach to industrial automation, focusing on the development of an automated system for erecting and filling cardboard boxes with wax jars. The project, executed in collaboration with Odigo Consulting and Scandinavian Hair Company (SHC), aimed to showcase enhanced production efficiency for small and medium-sized enterprises through the implementation of co
When humans are involved, things can go wrong. This is a statement as factually true and yet dramatically undefined and dangerously ambiguous as any. No matter the industry or domain, where humans interact with other humans, perfect predictability is impossible and a focus on negative outcomes can seem natural. When outcomes are anything less than ideal and when these events and outcomes are made
Plastic residues can fragment into nanoplastics and bring various pollutants to the soil, which results in a massive environmental risk that is endangering entire ecosystems. Soil protists, as a vital part of microbial food webs and carbon cycles, are also considered to be strongly affected by the presence of nanoplastics. Until now, many studies have found that plastic residues can have either po
As digital platforms play an increasingly significant role in the global economy, anti-monopoly identification and regulation face new challenges, particularly concerning the abuse of dominant position by digital platforms. This thesis analyzes the characteristics of platforms, including their multi- sided market nature, scale effects, and lock-in effects, highlighting how these factors complicate
This thesis defines the finite projective plane and the affine projective plane. A method of construction is defined for the field planes by extension of the affine plane constructed from the vector space over a finite field. The thesis explores for which orders planes can and cannot be constructed, in particular, for the prime powers there exist planes. For n=6 a computer search is conducted usin
When a sliding door is opened there is a sudden current peak that the electric network is subjected to. As a result of this it is difficult to design a power supply that operates the door with adequate performance while still maintaining a low power rating. In the current solution the power rating is designed for the sudden peaks and as there is no buffer of energy everything has to be taken direc
The pharmaceutical industry uses animal models in a variety of settings including safety, pharmacodynamic modelling and efficacy. Conventionally, a frequentist design of standard animal experiments of human asthma replication includes repeatedly running treatment groups with the exact layout, focusing on effect size rather than capturing historical data of animal responses on compounds of interest
Studies of grief have linked the experience of loss to multiple emotional, cognitive and physiological impairments but its behaviour across different cultures is insufficiently investigated. In this study, symptoms of grief and their relationship to negative psychological outcome among bereaved Jamaicans were assessed. A sample of (N=58) participants completed measures of grief and psychological d
Atherosclerosis, a chronic inflammatory condition, is the main attributor to cardiovascular disease. As such, elucidating the underlying immunological events that occur during atherogenesis has become an area of interest to better understand atherosclerotic pathology. T cells are an integral component of the adaptive immune response and have been shown to be present in atherosclerotic plaques. How

Research Question: Did the COVID-19 pandemic change the effe
Electronic Health Record (EHR) systems are central to modern healthcare, yet their practical impact on clinical workflows remains complex. This thesis explores the advantages and limitations physicians experience when using EHR systems in daily hospital work. Guided by the Systems Engineering Initiative for Patient Safety (SEIPS) framework, the study takes a socio-technical approach, focusing on h
Modern medicine is rapidly evolving toward personalized treatments, where therapies are tailored to an individual’s genetic profile. This shift is driven by the promise of pharmacogenomics, which aims to match patients with the most effective medications based on their unique biological makeup. As a result, biotherapeutics made from biological sources like proteins, peptides, and antibodies are be
Radar has come a long way since its invention in the 1930s. It is not only used to detect the distance and angular position of a target but can also measure velocity thanks to the Doppler frequency shift. In more advanced systems, the radar can perform tasks such as imaging and classification of the target. In some cases, full or partial polarimetry is used to gain additional information about the
Straumann® Emdogain® is a protein-based gel used in dentistry for tissue regeneration. Emdogain® contains enamel matrix proteins, which are mainly amelogenin proteins. These are obtained through weakly acidic extraction from porcine tooth buds. Embedded in the enamel matrix is also hydroxyapatite which releases calcium ions. These ions saturate the solution, and the protein extraction halts. An at
We introduce and discuss unitary equivalence of operators in the Cowen-Douglas class $B_n(\Omega)$. We prove that operators in the Cowen-Douglas class are unitarily equivalent if and only if there exists a holomorphic matrix $M$ which satisfies $\tilde K_\lambda(z)=M(z)K_\lambda(z)M(\lambda)^*$ for the spaces' kernels. We use this to establish that $\Delta_\lambda\log\lvert\lvert k_\lambda\rve
