Pollution from tire wear particles (TWPs) is a growing concern in environmental and health sciences due to their widespread release and potential toxicity. Even though TWPs are recognized as a major source of environmental pollution, knowledge about their interactions with biological systems and impact on health remains limited. Lab-generated particles allow studies of particle characteristics suc
Organic micropollutants comprise a diverse set of molecules, varying both with regard to the frequency of their use, as well as the potential harm they can inflict upon aquatic ecosystems. Ozonation has been recognized as an efficient method for their abatement, due to its ability to selectively oxidize molecular groups commonly found on organic molecules. Micropollutants are, however, rarely degr
This thesis explores how disaster-affected communities in the Kavre and Bardiya districts of Nepal perceive and experience cash assistance projects. The research was guided by two core questions: (1) What are community members' perceptions and preferences of cash assistance in disaster affected areas in the Kavre and Bardiya districts of Nepal? (2) How could these community perceptions and pre
To reduce reliance on energy-intensive, chemically synthesised nitrogen sources in microbial cultivation, we investigated the integration of the nitrogen-fixing bacterium Azotobacter vinelandii into a bioconversion process with the recombinant yeast Saccharomyces cerevisiae. Our objective was to develop a more sustainable approach by utilising biological nitrogen fixation to supply ammonium direct
With the development of the global economy and human society, population growth and urbanization, water resources are becoming more and more important, and the monitoring of water resources is also crucial. Therefore, this article designed a system for monitoring PH level in water, and designed a wireless transmission system based on LoRa technology. According to the actual application requir
This thesis proposes a hierarchical clustering algorithm for time series, comprised of a variational autoencoder to compress the series and a Gaussian mixture model to merge them into an appropriate cluster hierarchy. This approach is motivated by the autoencoders good results in dimensionality reduction tasks and by the likelihood framework given by the Gaussian mixture model. In contrast to simi
Title: The mediating role of Organizational Capabilities between Environmental Regulations and Environmental Innovation. Keywords: Environmental Innovation, Organizational Capabilities, Environmental Regulations. Research question: How do environmental regulations impact environmental innovation through organizational capabilities? Methodology: This research has been conducted through a singl
This thesis presents a numerical study of the beyond mean field extended Gross-Pitaevskii equation for a two-component self-bound Bose-Einstein condensate, supplemented by analytical work. We extend the quasi-two-dimensional system's mean field particle-particle contact interaction by quantum fluctuations (LHY-correction). We investigate the formation of self-bound droplets without external co
The induction of recombinant expression in bioprocesses is associated with high costs, but still suffers from unoptimised standard procedures with high use of IPTG. A flow-based online method for enzymatic analysis of recombinant expression in E. coli could greatly help in mapping induction behaviour, and assembly and programming of a FlowSystem for automatic sampling was done. The process was nev
Building on the idea that luxury goods can signal information about the self, such as wealth and status, to others, several attempts have been made to discover whether luxury goods have signaling functions specific to relationships. Past research showed that women’s luxury products might signal their partners’ devotion to them. The current research tested this devotion signaling function of luxury
This text sets out to examine what the general quantitative drivers of corporate credit ratings are. The result from an OLS regression identifies the following drivers: sales, the size of EBITDA in relation to debt, profitability, and interest coverage. When comparing the ratings from the agencies on a stand-alone basis, there are some differences. While interest coverage is a driving factor of S&
The main aim with this master’s thesis was to study the possibilities of detecting an event (rat trap going off) by analyzing audio streams from a MEMS (micro-electromechanical systems) microphone or movement patterns from a MEMS accelerometer. To achieve this goal, a small, power efficient and cost efficient embedded system was built with the help of a development board, a MEMS accelerometer, a

The HemaExplorer (http://servers.binf.ku.dk/hemaexplorer) is a curated database of processed mRNA Gene expression profiles (GEPs) that provides an easy display of gene expression in haematopoietic cells. HemaExplorer contains GEPs derived from mouse/human haematopoietic stem and progenitor cells as well as from more differentiated cell types. Moreover, data from distinct subtypes of human acute my
We present recent developments in modelling and simulation of internal traverse grinding, a high speed machining process which enables both a large material removal rate and high surface quality. We invoke a hybrid modelling framework, including a process scale model, simulations on a mesoscale capturing the proximity of a single cBN grain and an analysis framework to investigate the grinding whee
Not only the fat content but also the composition of fatty acids (FAs) in stored triglycerides might be of interest in the research on nonalcoholic fatty liver disease and nonalcoholic steatohepatitis. In this study, a novel reconstruction approach is proposed that uses theoretical knowledge of the chemical structure of FAs to simultaneously quantify the fat fraction (FF) and the FAs composition (
This study presents a novel approach to determine the steady-state performance of a self-excited induction generator (SEIG). The method gives an intuitive understanding of the effects of loading on the steady-state performance of the SEIG, without requiring any major mathematical effort. The steady-state no-load voltage of the SEIG is determined as the intersection between the generator no-load cu
