Populärvetenskaplig sammanfattning:En studie publicerad av NASA:s Goddard Institute for Space Studies år 2019 visade att de genomsnittliga globala temperaturerna under de senaste fyra åren (2015-2018) var de högsta som någonsin registrerats i människans historia. Den nyheten passar väl in i de alarmerande prognoserna om global uppvärmning, och kräver snabba och radikala handlingar. Att studera “teInnovative design and materials are needed to satisfy the demand for efficient and scalable devices for electronic and opto-electronic applications, such as transistors, LEDs, and solar cells. Nanostructured III-V semiconductors are an appealing solution, combining the excellent functional properties of III-V materials with the flexibility typical of nanostructures, such as the nanowires (NWs) stu

This mapping provides an overview of different types of arenas where the two concepts Ecosystem-based adaptation (EbA) and Blue Carbon (BC) are discussed. EbA has been defined by the Convention on Biological Diversity (CBD) as “The use of biodiversity and ecosystem services as part of an overall adaptation strategy to help people to adapt to the adverse effects of climate change.” (CBD, 2009). BC

The realization that the extraction and combustion of fossil fuels is having serious effects on the environment and the climate, together with the ever-growing need for fuels, has led to the development of the concept of the biorefinery. Biorefineries are refineries in which fossil resources, such as oil, are replaced by renewable biomaterials to produce biofuels and biochemicals. Non-edible bioma

This thesis deals with estimation and classification problems of non-stationary processes in a few special cases.In paper A and paper D we make strong assumptions about the observed signal, where a specific model is assumed and the parameters of the model are estimated.In Paper B, Paper C, and Paper E more general assumptions about the structure of the observed processes are made, and the methods

Due to advances in technology the amount of images from portable cameras has increased tremendously in recent years. Nowadays, most new mobile phones and cars have multiple cameras. Drones and other robots are often equipped with cameras as well. To be able to capture an image is not the same as to understand the content of it. Computer vision deals with the task of giving machines the ability to

Background: Vascular-targeted photodynamic therapy, a novel tissue-preserving treatment for low-risk prostate cancer, has shown favourable safety and efficacy results in single-arm phase 1 and 2 studies. We compared this treatment with the standard of care, active surveillance, in men with low-risk prostate cancer in a phase 3 trial. Methods: This randomised controlled trial was done in 47 Europea

Background. Natural gas makes a significant contribution to the current energy supply and its importance, in relation to both the German and worldwide energy supplies, will increase further in decades to come. In addition to its high degree of efficiency, the low level of direct GHG combustion emissions is also an advantageous factor. However, around 90% of natural gas is methane (CH4), which is t

Hematological malignancies are defined by their underlying genetic alterations, many of which are used to diagnose patients to classify them to different risk groups that dictate the therapy given. Recent advances in high-throughput sequencing have highlighted the presence of co-occurring genetic lesions and that they may form distinct genetic clones that evolve throughout disease progression. Acu

Pain is a major health issue for each affected individual and has a large impact on health costs. Most of our knowledge about this defensive system rely on data from different animal experiments. There is an obvious need for a translational pain model allowing comparisons between experimental animals and humans. UVB irradiation of skin has been introduced as a valid translational pain model and th

Mining, seen as a source of revenue in most developing countries, threatens seriously the environment. Mining impacts the water quality and one of the main problems of mining is acid mine drainage. Low pH and high concentration of heavy metals characterize acid mine drainage. When a stream is impacted by acid mine drainage both human activities and the ecological system are seriously affected. In

The need for more functionality and higher performance has increased the number of transistors to billions in current processors. A high number of transistors on the same chip area increases the power density, which in turn heats up the devices and lowers the life time of batteries. The increasing demand for devices relying on battery and harvested energies in the Internet of Things (IoT) era has

Purpose: Many centers aim to plan liver transarterial radioembolization (TARE) with dosimetry, even without CT-based attenuation correction (AC), or with unoptimized scatter correction (SC) methods. This work investigates the impact of presence vs absence of such corrections, and limited spatial resolution, on 3D dosimetry for TARE. Methods: Three voxelized phantoms were derived from CT images of

National incidence and prevalence estimates of homelessness in Canadian youth are unknown. However, a recent annual profile of shelter users in a large urban centre estimated that one in five consumers of emergency shelter services are youth. Adolescence is a period of vulnerability from developmental perspective. In their progression from childhood to adulthood, youth have multiple role transitio

We can more and more often hear in the media about multinational corporations conducting human rights abuses. This is due to the fact that this discussion, surrounding corporations and human rights, is a hot item on the agenda today. Higher demands are put on the companies to follow human rights and to take more responsibilities in the promotion and protection of human rights. One of the reasons f

Under början av 1900-talet införde alla nordiska länder, förutom Norge, en möjlighet för frihetsberövade kvinnor att medföra sitt spädbarn i anstalten under straffverkställigheten. Regleringarna grundades på arvsbiologiska aspekter, då det var vanligt att de små barnen fortfarande ammades av sina mödrar och de var beroende av modersmjölken för att överleva. Med tiden har dock regleringarnas syfte In the beginning of the 20th century all Nordic countries except Norway introduced a possibility for imprisoned women to bring their infants with them during their sentence. The legislation was considered necessary due to the fact that the infant still was breast-fed by their mother. Child psychologist and psychoanalysist John Bowlby (from Great Britain) developed the affiliation theory during th

Betsafe is still a young company that have seen a great success in a short span of time. To remain successful it is therefore important that they don’t become complacent and remain visionary. However, a successful company must also balance its risk‐taking. In the end it is vital to find the right opportunities that fits the company and of course to be able to make the right decisions. In this proj

The study comprised two parts, a questionnaire survey and a set of field measurements. The purpose of the study was to link laboratory studies

A risk evaluation with regards to fire safety has been performed at Torpa Stenhus. The focus of the evaluation was the safety of the people inside the building in case of a fire. As part of the education for future fire protection engineers at LTH a risk evaluation report is performed in the course Brandteknisk riskvärdering (VBR054). Torpa Stenhus was built during the 15th century and is located

Abstract Toxic cyanobacterial blooms can form in both freshwater and marine environments, which could threaten the health of human beings and animals. The genera that are known for causing the scums in freshwater are Anabaena, Microcystis, Cylindrospermopsis and Planktothrix. In order to control lake water quality and minimize the potential health risk associated with the cyanobacterial blooms, th
