CONTEXT: Uptake of organic farming falls short of stated sustainability targets, particularly in highly productive regions where adoption could mitigate environmental impacts of intensive farming. Several hypotheses have been advanced to explain the constraints on adoption, but these have not been assessed within an integrative, interdisciplinary framework.OBJECTIVE: The objective was to develop a
For plasma-wakefield accelerators to fulfill their potential for cost effectiveness, it is essential that their energy-transfer efficiency be maximized. A key aspect of this efficiency is the near-complete transfer of energy, or depletion, from the driver electrons to the plasma wake. Achieving full depletion is limited by the process of re-acceleration, which occurs when the driver electrons dece
This doctoral thesis investigates mediaeval earthenware production, distribution and consumption based on material from Lund, Sweden, moving beyond simple technological shifts to explore the interplay of material factors, social practices, and economic influences. It presents a typology of hard greyware, redware and glazed redware, as well as the chemical analysis of circa 400 samples. The study a
Feedbacks from the climate to other components of the coupled human-Earth system are expected to strongly influence the co-evolution of human society and its environment. Representing these feedback loops between climate and society, via the Earth system's response to human activities and the subsequent effect back onto social systems, is essential in order to fully explore the dynamics of the cou
Background Coronary microvascular dysfunction (CMD) is associated with a poor prognosis but is difficult to diagnose non-invasively. In a recent paper, ST-segment depression on exercise-ECG was found to have a very high positive predictive value (PPV) for CMD in a highly selected group of patients. Objectives In the present study of chest pain patients, we used myocardial perfusion single photon e
Extreme weather events pose significant threats to urban health in low- and middle-income countries, particularly in sub-Saharan Africa where there are systemic health challenges. This paper investigates health system vulnerabilities associated with flooding and extreme heat, along with strategies for resilience building by service providers and community members, in Accra and Tamale, Ghana. We em
It is now widely accepted that the vast majority of inhabitants of cities in developing countries have to be involved in the construction of their houses if they are to become home-owners. During the construction process, most households will make payments for land, construction materials and skilled labour. This chapter analyses the different ways in which households finance these payments and fo
In Africa, young people are engaging with a globalised world of flows and movements but are coming of age in environments characterised by uncertainty, economic hardship and unemployment. Drawing upon research conducted in Madina, a suburb of Accra, a social navigation perspective is adopted to explore young people's everyday mobility and their aspirations for future mobility. By drawing attention
Forests are integral to the global carbon cycle, acting as major carbon sinks, though their capacity can be altered by climate and land use changes. India has a diverse forest ecosystem, but the dynamics and changes in its carbon stocks under a changing climate are not well understood. This study investigates the regional and temporal changes in vegetation carbon biomass (VCB) within Indian forest
This study investigated the retention of spatial knowledge in buildings following route-learning training in a virtual reality environment. A total of 121 participants were tested up to three months later on putting waypoints of the route in the correct order and recalling directions at waypoints. Memory accuracy declined over time, consistent with classic memory theory. Route knowledge was retain
In the past decades, the number of research work explaining the load transfer mechanism of moment connections has increased due to their advantages of energy dissipation capacity and improved load distribution. The use of bolts in slotted-in plate moment connections is a common practice in timber construction. However, the design and application guidelines are still limited and leading to results
The negative relationship between birth interval length and neonatal mortality risks is well-documented, but the possibility of heterogeneity in this relationship has been largely ignored. Understanding variation in the strength of this relationship may be important for adjusting family planning programs strategies for issues regarding fertility regulation and maternal and child health, however, a
The European commission have set targets regarding the reduction of emission of greenhouse gases, the improvement of the energy efficiency and the use of renewable resources of energy respectively by 20 % by the year of 2020. Swedish targets are even more ambitious compared to the European Commission that aims to reduce the greenhouse gas emissions by 40 %, improve the energy efficiency by 20 % an
International students at Lund University are constantly engaged with their mobile devices. Communication conducted through these devices across a variety of digital and social media platforms facilitates a significant amount of everyday communication, on both a local and transnational level. The overall aim of this thesis is to examine how these increasingly digitally mediated communicative pract
Amelogenin is a multifaced protein, playing an essential role in the formation of enamel where it directs the biomineralisation of hydroxyapatite. The self-assembling properties of amelogenin are highly applicable in the development of novel biomaterials and drug-delivery platforms, and the regenerative properties of the protein are today widely explored in clinical dentistry and wound healing.

Over the last few years, the user-generated video-sharing online platform YouTube has been recognized by the academia as well as mainstream media as an arena for predominately rightwing political content, and radicalizing far-right extremism in particular. This thesis introduces and explores the construction of a new digital left in the left-wing phenomenon LeftTube on YouTube. Through using criti
