It has been suggested that electromagnetic fields (EMFs) act as a promoter late in the carcinogenesis process. To date, however, noconvincing laboratory evidence has been obtained indicating that EMFs cause tumour promotion at non-thermal exposure levels. The effects of EMF exposure in a rat brain glioma model were investigated. The exposure consisted of 915 MHz microwaves, both as continuous wave
The transition towards renewable energy technologies is essential to mitigate climate change. However, the intermittency of Variable Renewable Energy (VRE) such as wind and solar creates seasonal imbalances in the electricity supply. To address this, inter-seasonal energy storage solutions are needed. Produced via electrolysis from excess electricity, hydrogen offers a promising storage medium. Ho
Semantic search using large language models (LLMs) combined with an approximate nearest neighbor (ANN) index is the current state of the art in search technology. Semantic search aims to match a user’s search query based on its contextual meaning and intent with a highly relevant search result, rather than relying solely on matching keywords. While semantic search is superior to keyword-based sear
The National Archives of Sweden have been given the task of standardising the management of electronic records in the public sector so as to ensure long-term storage and readability of these records in electronic archives. Standardisation is a powerful tool which eases transferability and prevents obsolescence. International organisations, including the EU, have long been producing and managing st
Water for Injection (WFI) is a critical utility in pharmaceutical manufacturing, traditionally produced through an energy-intensive distillation process. This thesis investigates the feasibility of a more sustainable alternative, ambient WFI production using membrane-based purification technologies combined with ozonation in the storage and distribution loop. Conducted in collaboration with AstraZ
This study examines how self-tracking technologies are repurposed within the creative practice of GPS art, focusing on how meaning is produced when tools designed for optimization and behavioral regulation are redirected toward expressive and communicative ends. The motivation for this inquiry lies in the need to understand the relationship between humans and machines beyond deterministic accounts
Following the Urgenda climate court case in the late 2010s, Greenpeace cooperated with a group of Bonairean residents to take the Dutch state to court again in 2024 in relation to climate neglect. According to the plaintiffs of the Bonaire case, the Caribbean island that is part of the country of the Netherlands is structurally neglected when it comes to climate adaptation and mitigation. On top o
This study explores how Lund University students navigate everyday food purchasingdecisions in order to better understand young consumers’ needs and behaviours. As Europeanfarmers face growing competition from cheaper imported goods, understanding consumerbehaviour becomes increasingly important for creating more sustainable and locally resilientfood systems (Loughlin, 2024). Students were selecte
Ett problem med parkeringsapplikationer är att användare ofta glömmer att avsluta aktiva parkeringssessioner, vilket leder till överbetalning. Denna uppsats designar och utvärderar automatisk avslutning av parkering på ett sätt som minskar överbetalning samtidigt som användarnas tillit och kontroll bevaras, samt utvärderar resultatet. Projektet resulterade i en testapplikation för iOS med en automA problem with parking applications is that users often forget to end active parking sessions, which leads to overpayment. This thesis designs and implements automatic parking termination in a way that reduces overpayment, while preserving user trust and control, as well as evaluating the results. The project resulted in an iOS test application with an automatic termination feature called AutoStop
As firms increasingly operate in markets characterised by competition, uncertainty, regulations, and shifting consumer demands, understanding how business models (BMs) are reconfigured has become increasingly important. Against this background, the study aims to increase the understanding of how regulations and consumers, as exogenous forces, influence the reconfiguration of business model compone
Large-scale landforms originated from jökulhlaups or glacial lake-outburst floods (GLOFs), and their small-scale components help in recognising the sedimentary environment of the flood. The GLOF fans that developed along the Pleistocene ice-sheet margin have not been investigated in detail, and north-eastern Poland, with its Megaflood Landform System and Bachanowo and Szeszupka fans, seems ideal f
This paper presents a model for micron-sized aluminum (Al) particle combustion in hot oxidizing environments, forming hollow spheres. The model comprises four sub-models describing the physical and chemical processes during Al combustion: melting of the solid core, ejection of liquid Al droplets from the breaking solid shell, vaporization of liquid droplets, and ignition and establishment of vapor
Purpose: This paper aims to challenge the view of Sweden’s climate leadership by problematizing its domestic climate adaptation governance and highlighting the need for a more holistic view of adaptation. The paper highlights aspects that are troublesome for not only the built environment along coastlines but also the future of Sweden’s standing as a climate leader. The paper concludes with recomm
Dissolved organic matter (DOM) plays a central role in soil carbon (C) dynamics, serving as both a substrate for microbial decomposers and a source of material stabilised via physical protection in molecular aggregates and associations with mineral particles. It is well established that soil microorganisms play a key role in mineral-associated C aggregates; however, their impacts on molecular aggr
Formation of hydrated magnesium carbonate (HMC) cement phases from the carbonation of brucite has been investigated using synchrotron radiation (SR) based scanning transmission X-ray microscopy (STXM) at Mg and O K-edges. HMC is formed from the reaction of brucite and sodium bicarbonate in water. The introduction of magnesium acetate as a ligand influences the characteristics of the resulting prec
The need for red blood cells to transport oxygen and CO2, blood platelets to stop bleedings, and neutrophils, macrophages, B- and T-cells for host defense, is a prerequisite for life. These mature blood cells have a limited life span and are thus constantly replenished by an enormous cell production (estimated to 1012 cells per day) which primarily takes place in the bone marrow (BM). Mature blood
One of the common tools for studying the deformation behavior of the microstructure in polycrystalline materials is crystal plasticity models. These are used to describe texture evolution and hardening due to crystallographic slip. A drawback when using crystal plasticity models is that the calculation of the slip requires solving a set of stiff differential equations for each grain in the microst
Avhandlingens syfte är att undersöka effektiviteten av tillgång till rättvisa för ursprungsbefolkningar i ljuset av rättigheterna till landområden, territorier och naturresurser. Detta kommer att göras genom att undersöka både rättspraxis från Interamerikanska domstolen för mänskliga rättigheter (och ett fall från Högsta domstolen i Brasilien), den rättsliga ramen på internationell nivå och andra The thesis's purpose is to look into the effectiveness of access to justice for indigenous peoples in the light of the rights to lands, territories and natural resources. This will be done by looking into both the jurisprudence of the Inter-American Court of Human Rights (and one case from the Supreme Court of Brazil), the legislative framework on an international level and other relevant sour
A steam methane reforming reactor is a key equipment in hydrogen production, and numerical analysis and process control can provide a critical insight into its reforming mechanisms and flexible operation in real engineering applications. The present paper firstly studies the transport phenomena in an industrial-scale steam methane reforming reactor by transient numerical simulations. Wall effect a
The quality and performance of products are particularly important in sectors such as research facilities and in the nuclear, military and space industries. These sectors make use of high-performance materials that are uncommon in other contexts and therefore place high requirements on personnel, machines and tools. While tool manufacturers have readily available tool selection guides and cutting
