Pebble accretion is recognized as a significant accelerator of planet formation. Yet only formulae for single-sized (monodisperse) distribution have been derived in the literature. These can lead to significant underestimates for Bondi accretion, for which the best accreted pebble size may not be the one that dominates the mass distribution. We derive in this paper the polydisperse theory of pebbl

High latitude peatlands play a significant role in global soil carbon budgets, attributed to the slow decomposition rate of Sphagnum mosses that facilitates carbon sequestration through the build-up of peat. As climate change is predicted to increase soil temperatures and decomposition rates of organic matter, studying environmental and intraspecific mechanisms that controls decay resistance of Sp

Denna uppsats undersöker sambandet mellan kurering och vertikal integration i strömningstjänster på den svenska bokmarknaden. Det empiriska materialet består av en intervju med strömningstjänsten Storytel, intervjuer med tre svenska förlag samt extern kommunikation från BookBeat och Storytel. I uppsatsens empiriska material ingår även en kvantitativ granskning av innehållskureringen hos BookBeat o

Syftet med uppsatsen har varit att undersöka hur fenomenet ”director’s cut” kan komma till uttryck inom litteratur. Detta har undersökts genom en fallstudie med utgångspunkt i följande titlar: A Clockwork Orange, The Stand Complete and Uncut Edition och Life and Death: Twilight Reimagined. Utifrån dessa avsåg uppsatsen att undersöka vad de bakomliggande syftena till utgivningen var, samt hur recep

Analytical chemistry is a sub-discipline of chemistry that even young schoolchildren encounter at an early stage in their education. Gravimetry and measurement uncertainties are aspects that form a part of such education, as well as measurements of pH and colorimetry. These are all an integral part of children’s early educational experiences, which shows the importance of this discipline within th

This thesis examines the development and deployment of artificial intelligence technologies in news media organisations. Here a framework is proposed to analyse new AI and digital technologies and their introduction within the news media and journalism sphere. The framework consists of three stages: applications and implications, and actors (AAI). The first stage of applications considers the tech

Visuell kommunikation spelar en avgörande roll i hur budskap förmedlas på sociala medier där ett visuellt språk överskrider språkliga barriärer och möjliggör enklare bearbetning och tolkning av information än skriven text. Det är därför av stor vikt att undersöka hur en influencer i svensk kontext använder visuell kommunikation på sociala medier. Med en mixad metod syftar denna uppsats till att an

Syftet med denna uppsats är att undersöka hur brottsoffer, förövare och vittnen framställs i svenska true crime-poddar av aktörerna public service, kvällstidning och en självständig aktör. Vidare diskuteras hur press- och medieetik utmanas av poddar om true crime. I ett allt mer digitaliserat samhälle kan vem som helst publicera material om verkliga brott på olika plattformar. Dagligen produceras

This research project examines the research on safe and forced repatriation and how those concepts have been contested in research, especially in the case of Syrian repatriation from Lebanon. It focuses on how there needs to be nuance and fluidity added to the perception of safe repatriation. It suggests that voluntary repatriation is a disguise for forced repatriation and that research needs to f

Among foreign-born women there is a significant employment gap compared to native women as well as foreign-born men. At the same time public institutions have been deemed as unable to deliver labor market integration efforts that are adapted to the needs of foreign-born women, which has been pointed out as a necessity. In this context, civil society-municipal partnerships have been recognized as a

The current way of consumption and production is unsustainable in that society is exceeding the earth’s planetary boundaries and creating long-term and irreversible effects on an environmental, social, and economic level. There is a recognized need on all system levels to change the way that we operate. Industry is a key area that requires this attention, as it is largely responsible for the impac

This text aims to identify the political framework of the human rights regime and compare the regime's historical and current political framework. This question is essential and deserves research as it explains how the regime has developed its policies and advocacy over its history and elucidates the reasons behind several of the most damaging and contentious challenges the human rights advoca

Denna uppsats undersöker influencers roll på den samtida svenska bokmarknaden. Syftet i denna uppsats är att belysa svenska influencers samtida samarbeten på Instagram med Storytel. Diskursen ska föras till ett bredare perspektiv om litteraturens villkor på den svenska bokmarknaden.

Although people with cardiovascular conditions were subjected to more rigorous restrictions during the COVID-19 pandemic, there is limited knowledge of how the restrictions affected their lives and well-being. Thus, the aim of this study was to describe how people with cardiovascular conditions experienced their life situation and physical and mental health during the second wave of the pandemic i

Purpose: The purpose of the study is to gain an understanding of how Swedish millennials perceive the image of luxury textile brands that have always relied on animal leather and now are introducing plant-based vegan leather textiles. Methodology/Empirical data: The study is based on the foundation of social constructionism philosophy. A qualitative research design is followed in the present stud

The operation of a froth flotation column can be described by a nonlinear convection–diffusion partial differential equation that incorporates the solids–flux and drift–flux theories as well as a model of foam drainage. The resulting model predicts the bubble and (gangue) particle volume fractions as functions of height and time. The steady-state (time-independent) version of the model defines so-

Aims: To develop a suite of quality indicators (QIs) for the evaluation of the care and outcomes for adults with pulmonary arterial hypertension (PAH). Methods and results: We followed the European Society of Cardiology (ESC) methodology for the development of QIs. This included (i) the identification of key domains of care for the management of PAH, (ii) the proposal of candidate QIs following sy
