Lignin, the most abundant aromatic polymer in nature, is a valuable renewable resource due to its high phenolic compound content. Utilizing depolymerized lignin for the bioproduction of valuable industrial precursors such as muconic acid has garnered significant attention. In this study, several genetically modified strains of Pseudomonas putida were constructed to bioconvert vanillin and guaiacol
Introduction: Continuous Manufacturing involves the continuous feeding of input materials into the transformation of in-process materials within, and the concomitant removal of output materials from a manufacturing process based on ICH guideline. In these systems, all the processes from raw material to final finished product would be continuously produced. The project aims to: Investigate the chal
As plastic pollution in aquatic environments keeps happening it has become more and more important to learn more about nanoparticles. Bio-based and biologically degradable plastics, such as polylactic acid (PLA), are gaining popularity and it is therefore important to determine whether they break down into nanoplastics or not. Should this be the case, it is of interest to characterize their size,
The goal of this thesis has been to evaluate the design guidelines that currently exist regarding designing for metal additive manufacturing (AM). More specifically, this project has focused on the design guidelines regarding thin-walled features and how well they work when applied to adapt an industrial part for manufacturing with the AM process laser powder bed fusion (L-PBF). Making the walls
The aim of this thesis project was to develop or lay the base for an innovative oat and chickpea based fermented product. From a previous thesis project, Glucanova AB had developed an oat and chickpea base called OatChic®. The goal of this thesis project was to evaluate the effects of fermentation on OatChic® by characterizing prototypes based on the beta-glucan content, phytic acid content, sugar
With the technological advancements of the 21st century, online pornography has become increasingly available to children and adolescents, and this research aims to investigate how individuals who started watching pornography at an early age experience pornography. The study implements a phenomenological approach and is based on 13 qualitative interviews with participants who started watching p
I denna studie undersöks Djurgårdens IFs supportrars identitetsskapande och medieanvändning med syftet att ge ett nytt perspektiv inom forskning om den svenska supporterkulturens påverkan på individen. Tre kvalitativa intervjuer förs med hängivna fans av fotbollsklubben för att samla in empiriskt material. Materialet analyseras utifrån identitetsteori och det ritualistiska synsättet på kommunikati
In Europe, there are still a significant amount of residential fires. Particularly fires in the living room are a major threat to the occupants. Much research has been done to residential fires. However, there is still little known about the impact of the development of building structures and building content on the fire behaviour and room conditions. This report shows a clear view of how these d
This work investigates visualizations of two crises; terrorism and climate change. Focus lies on mediated images concerning Paris 2015, where terrorist attacks had an impact on the following UN climate change conference (COP21). The symbol of the Eiffel Tower was used to portrait both issues and will be studied through a semiotic analysis. Terrorism and climate change are argued to be interlinked,
This thesis examines the shareholder value creation of IP in M&A. Using a unique patent-M&A data set over the period 2006 to 2016, we show that acquirers of companies holding IP gain significantly more shareholder value than acquirers of targets not holding IP. We find that this only holds as a binary relationship, and that the discrete relationship between shareholder value and IP is nega
This thesis presents the results of an evaluation of the performance and determinants of fund flows for selected Impact Investing and Socially Responsible Investing portfolios of funds. The impact of current and past measures of monthly and annual financial return are considered from the perspective of potential investors. The results show that Impact Investing funds out-performed general market v
This thesis describes the characterization of the rheological properties of dense suspensions of sodium caseinate and micellar casein with respect to changes in concentration (100-200g/L), pH (7.0-5.3), charge density (Δα), and temperature (5-40°C). The relationship between pH and charge density and how this relationship is affected by changes in temperature and concentration were also addressed.
Mass Spectrometry- based proteomics has matured to an analytical tool applicable in many areas of life science. Although, limitations remains where much focus has been towards the development of search engines to more accurately identify peptides in fragmentation spectra. This report aims to investigate four search engines; MSGF+, Andromeda, MSFragger and pFind in order to assess the advantages an
Periodic Shadowing is a software post-processing technique for suppressing stray light. A proof-of-concept was recently published so an analysis of the involved parameters is needed to allow for a deeper understanding of the technique. In this project the three most important parameters in the technique are analyzed and their impact on the results of optical spectroscopy measurements is evaluated
The Japanese language has as any other language been grammaticalized throughout history. Many different aspects regarding the Japanese language has at some point underwent this phenomenon. However, the aspect that will be considered in the following disquisition is the Japanese auxiliary verbs, with consistent focus on the two verbs oku and shimau. These two verbs have when used a grammatical mark
Income inequalities in developed nations are increasing and the issues of cause, effect and long run implications are currently being discussed and explored by economists and policymakers around the world. This thesis adds to the discussion by exploring income growth in Sweden; a country known for its equality and egalitarian society, yet has become one of the countries where income inequality is
Objective: Citrate is widely used in dialysis, either as an acid in dialysis fluids or as a regional anticoagulant. In both cases, the concentration of citrate in the plasma of the patients will increase above physiological levels, up to 5-foldes in some cases. The aim of this study was to investigate the effect of citrate on the transcriptional level, as well as on the metabolic level and elucida
The rise in global emissions of carbon dioxide and the need for new technologies to combat climate change has prompted extensive research into carbon capture methods. This master thesis focuses on a novel carbon capture absorption technology, developed at Lund University, that utilizes the amine 2-amino-2-methyl-1-propanol (AMP) in the organic solvent dimethyl sulfoxide (DMSO) to capture CO2. A ch
