The purpose of this thesis was to investigate how probit functions have changed based on research that has been conducted by RIVM in the Netherlands, and to investigate how the calculated risk evaluation changes when using new values derived in QRAs conducted in Sweden. The goal was to quantify any differences that might occur due to the changes in probit functions. To conduct this thesis a survey

Hållbart resande är idag viktigare än någonsin att ta hänsyn till. Det är inte längre fossildrivna motorfordon som allmänt anses vara vägen framåt i samhället. Resor bör helst ske med hjälp av transporter vars miljöpåverkan är så liten som möjligt, där gång, cykel och kollektivtrafik förväntas användas mer. I Lunds kommun och Malmö stad är fokus på hållbara transporter starkt närvarande i deras stTo travel sustainable means more than using sustainable transportation; it is important to ensure that the entire journey is sustainable for one to go from one destination to another. The purpose of the study is to investigate how the entire journey is addressed by municipalities' Master Plan and traffic and mobility documents. Specifically, the study analyzed the municipality of Lund and the

OBJECTIVE: This study investigated physical activity and its association with the development of islet autoimmunity and type 1 diabetes in genetically at-risk children aged 5-15 years.RESEARCH DESIGN AND METHODS: As part of the longitudinal Environmental Determinants of Diabetes in the Young (TEDDY) study, annual assessment of activity using accelerometry was conducted from age 5 years. Time-to-ev

The European Commission has established a mission to achieve 100 climate neutral cities by 2030. A key element in the process is for municipalities to develop a Climate City Contract (CCC). Simultaneously, Viable Cities, a national strategic innovation program in Sweden, is also focusing on the transition to climate neutral cities where CCCs are being developed. Viable Cities is at the forefront o

OBJECTIVE: To investigate the evolution of nailfold capillary density in patients with systemic sclerosis (SSc) in relation to immunosupressive treatment and autoantibodies.METHODS: Prospective study cohort. Consecutive newly diagnosed SSc patients were included into this study who, in a retrospective review, had at least 2 nailfold capillary microscopy (NCM) measurements performed during the firs

Monolithic heterogeneous integration of III-V semiconductors with the contemporary Si Complementary Metal Oxide Semiconductor (CMOS) technology has instigated a wide range of possibilities and functionalities in the semiconductor industry, in the field of digital circuits, optical sensors, light emitters, and high-frequency communication devices. However, the integration of III-V semiconductors is

Railways are vulnerable to extreme weather events. Some of these are expected to increase in frequency and severity in a warming world, prompting adaptation efforts. To inform these efforts, we have analysed railway operations data from Sweden in the period 2001-2020 to learn more about the past effects of extreme weather events on train delays. We have used a database containing some 1.6 billion

Ungefär hälften av alla cancerpatienter genomgår strålbehandling, antingen som en enskild behandling eller i kombination med kirurgi och/eller medicinsk behandling. Vid strålbehandling används högenergetisk joniserande strålning för att bekämpa cancerceller. Strålningen orsakar skador på tumörcellernas DNA, men kan även skada friska celler. För att uppnå bästa möjliga behandlingseffekt med minsta FLASH radiotherapy (FLASH-RT) is a promising new approach to radiotherapy that has the potential to transform the field. By administering radiation at ultra-high dose rates (UHDR) on a millisecond timescale, FLASH-RT may increase normal tissue tolerance compared to conventional radiotherapy while maintaining the anti-tumoral effect. However, the short treatment times present unique physical and te

Ground-level fine particulate matter (PM2.5) and ozone (O3) are air pollutants that can pose severe health risks. Surface PM2.5 and O3 concentrations can be monitored from satellites, but most retrieval methods retrieve PM2.5 or O3 separately and disregard the shared information between the two air pollutants, for example due to common emission sources. Using surface observations across China span

We first define a new multiplication on triangular Banach algebras. Then study amenability, weak amenability, biflatness and biprojectivity of these algebras.

As the dream of autonomous vehicles moving around in our world comes closer, the problem of robust localization and mapping is essential to solve. In this inherently structured and geometric problem we also want the agents to learn from experience in a data driven fashion. How the modern Neural Network models can be combined with Structure from Motion (SfM) is an interesting research question and As the dream of autonomous vehicles moving around in our world comes closer, the problem of robust localization and mapping is essential to solve.

The "Make, reuse, repair, recycle" is an alternative model to the the linear model "Take, make, waste" and aims to reduce the environmental impact of home deliveries, particularly by reducing the packaging waste. This model was tested in a real-life context in which the secondary packaging was returned and reuse multiple times. This model sets the scene to more circular and sustainable last-mile d
