Popular Abstract in Swedish Internationella diabetesförbundet räknar med att en tiondel av världens befolkning kommer att ha någon form av diabetes om 50 år. Diabetes är en sjukdom med global spridning som innebär att kroppen inte kan ta hand om all den näring man intar, framförallt inte sockret. Detta medför att sockerhalten i blodet höjs. Insulin produceras efter en måltid och signalerar till krIslet hormone secretion is tightly regulated by metabolic status as well as local and circulating factors. These factors can activate different receptors on the pancreatic islet cells, for instance G-protein coupled receptors (GPCRs). When activated, these receptors are able to fine-tune islet hormone secretion and regulate overall β-cell function. Estrogen and serotonin are circulating factors

Growing demand for transport biofuels in the EU is driving an expansion of the industry in developing countries. Large-scale production of energy crops for biofuel, if mismanaged, could cause detrimental environmental and social impacts. The aim of this study is to examine whether the newly adopted EU Directive 2009/28/EC and its sustainability certification system can effectively ensure sustainab

The three-year research project funded by MSB applies design science, in combination with traditional scientific investigation, to develop a method to guide the planning phase of capacity development projects for disaster risk reduction and climate change adaptation. The method facilitates local participation and ownership as it builds on the strengths of the Logical Framework Approach (LFA), whil

We present the design of a split-and-delay unit for the production of two delayed replicas of an incident extreme ultraviolet (XUV) pulse. The device features a single grazing incidence reflection in combination with attenuation of remaining infrared light co-propagating with the XUV beam, offering a high throughput without the need of introducing additional optics that would further decrease the

Knowledge of the forest biomass and its change in time is crucial to understanding the carbon cycle and its interactions with climate change. LiDAR (Light Detection and Ranging) technology, in this respect, has proven to be a valuable tool, providing reliable estimates of aboveground biomass (AGB). The overall goal of this study was to develop a method for assessing AGB using a synergy of low poin

Problem definition Nowadays society is very concerned with sustainability. Companies try their best to meet sustainability customers’ expectations and regulations. The adoption of Lean and Six Sigma could bring sustainability improvements, but it is not clear how these three areas are combined and how they are currently addressed by companies. Purpose Explore the relationship between Lean, Six Sig

Denna studie har genomförts på Tetra Pak för att studera deformation i vätskekartong under vikning. När en förpackning formas i fyllmaskinerna viks kartongen enligt biglinjerna. Det finns ett stort intresse av att studera vikprocessen då den är avgörande för den slutgiltiga kvaliteten av förpackningen. Matematiska modeller används för att simulera kartong men dessa kräver verkliga mätningar och dThis study has been conducted at Tetra Pak to study deformation in liquid packaging paperboard during the folding process. When a package is formed in the filling machines, the paperboard is folded according to the crease lines. It is of great interest to study the folding process since it is crucial to the final quality of the package. Mathematical models are used for simulation of paperboard bu

This thesis explores the correlation between national role conceptions, national identities and sensemaking processes among South Korean and Swedish policy influencers during the Sunshine Policy years of 1998-2003. The study relies on in depth semi structured interviews with 10 policy influencers who work with North Korea policies. Starting from Holsti’s (1970) national role conceptions and Weick’

I en allt mer globaliserad värld och efter den digitala revolutionen, har skyddet för personuppgifter hamnat i rampljuset. Numera, utbyts data över nätet dagligen för olika syften, såsom privata, kommersiella och allmänna, vilket har skapat en oro för hur dessa överföringar av personuppgifter kan påverka rätten till dataskydd och rätten till privatliv. Inom EU har det funnits en tradition av att In an increasingly globalized world and after a decade of digital revolution, the protection of personal data has fallen in the limelight. Nowadays, data is exchanged over the internet daily for various purposes, including strictly private, commercial, as well as public, which has raised concerns on how these transfers of personal data may affect the right to data protection and the right to priva

Image-based rendering for view synthesis is a field within computer vision that has seen a growing number of research activity within the past few years, much due to deep learning techniques emerging, allowing researchers to re-format view synthesis as a learning problem. The multiplane image (MPI) is a recently proposed learning-based layered 3D representation, created from one or a few input ima

With the growing adoption of data analytics and powerful algorithms in organisational decision-making, the ethical concerns surrounding algorithmic bias have become increasingly apparent. This research aims to explore the extent to which organisational characteristics (e.g., laws, policies, norms, and standards) and technology characteristics (e.g., transparency, user control, and auditability) ad

The Low Energy Beam Transport, LEBT, is the _rst part of the European Spallation Source accelerator, the ESS linac, that is currently under construction in Lund. The LEBT section, that will be installed and commissioned in early 2018, has the purpose of focusing and steering the low-energy proton beam that enters directly from the ion source. For simulation of the beam dynamics in the LEBT, ESS us

Parkinson’s disease (PD) is considered one of the most frequent neurodegenerative disorders amongst elderly people. PD leads to loss of dopaminergic neurons in substantia nigra of the brain giving symptoms such as slowness of movement and dementia. PD brains have been found to contain accumulations of a protein named alpha‐synuclein (α‐syn). Additional to its aggregation propensity in PD it is als

Introduction: The novel external beam therapy technique using ultra-high dose rates known as FLASH has become known for its normal tissue sparing effect. Currently in Lund, veterinary clinical trials are carried out on canine patients using electrons with ultra- high dose rates. By implementing a treatment planning system for FLASH-irradiation, the dose distribution can be visualized and the gantr

This thesis investigates how impact assessment can contribute to organisational learning and whether there are ways to enhance it. To answer these questions, the research takes a form of a qualitative case study carried out in collaboration with the non-profit organisation Reach for Change which represents a single case. The research data is drawn from two primary sources of evidence: organisation

In a world where the problem of energy resources, pollution and all aspects related to these issues becomes more and more dominant, a greater commitment is needed in the search for solutions. The goal of this project is to make a contribution to the research and development of new materials to reduce the environmental impact in some fields. First of all, we tried to synthesize and prepare an isati

The goal of this article is to propose, through the use of GIS software, an interdisciplinary method to suggest new touristic flows after the Covid-19 pandemic. Specifically, the aim is to identify those sites of cultural and landscape interest that are little known but with great artistic, cultural, historical and environmental value that could give new vigour to the tourism sector. In the first
