Air pollution research has been conducted in Europe and North America as well as in Asia and South America for decades, but there has, so far, only been a limited amount of studies on air pollution and its health effects conducted in Africa. Until recently, global inventories of pollutants from North America Europe and Asia have been used for air quality and climate change modelling in Africa (Bon
With the advent of nationwide mammography screening programmes, a number of natural history models of breast cancers have been developed and used to assess the effects of screening. The first half of this article provides an overview of a class of these models and describes how they can be used to study latent processes of tumour progression from observational data. The second half of the article
Due to the focus of their study program, environmental and sustainability students are vulnerable to experience negative emotional impacts, potentially affecting their mental health. This thesis contributes to increased understanding of emotions and emotional resilience in relation to the climate crisis by examining experienced emotions, studying the power students have over their emotions, and po
As the need to adapt to a changing climate and the political rhetoric in this regard are growing, Berlin’s Senate has issued strategic policies – complemented by an increase of funding. Berlin’s socio-cultural features and place-based factors seem predisposed for so-called “Nature-based Solutions” (NbS) that can support the achievement of adaptation efforts. This encouraging context seems to be co
Climate change is the greatest challenge of our time. Despite efforts to reduce greenhouse gas (GHG), the emissions contribution from global aviation is set to increase. Electric aviation has emerged as an alternative which could form part of the solution. Sweden, which is on the path to carbon neutrality and has a long history in aviation, could contribute to the global efforts in mitigating clim
Smart City is a paradigm for the development of urban spaces through the implementation of state-of-the-art ICT. There are two main approaches when developing Smart Cities: top-down and bottom-up. Based on the bottom-up approach, the concepts of Smart People and Smart Communities have emerged as dimensions of the Smart City, advocating for the engagement of citizens in Smart People initiatives. Th
Mycoplasma bovis (M. bovis) infections are difficult to diagnose and treat, causing severe economic losses to farms with infected cows. Eurofins Milk Testing Sweden AB screens cow’s milk using qPCR (quantitative Polymerase Chain Reaction) to detect M. bovis infections. Five performance characteristics were chosen to evaluate if ELISA (Enzyme-Linked Immunosorbent Assay) could replace the current sc
Simulations of large detectors such as the ATLAS detector at the LHC (Large Hadron Collider) are compute-intensive projects, and are according to current internal estimates expected to be consuming 40 % of the total ATLAS CPU resources in 2020, creating a need for software optimization strategies. We investigate build configurations of the Geant4 simulation software to find if a) a performance imp
Methylation of lysine (Kme) is known to regulate several important functions, altering gene expression and cell cycle progression. However, mass spectrometry based proteomic analysis of the modification has not been possible due to the lack of efficient purification strategies to enrich modified peptides for analysis. In this study, we identified and evaluated several in-house and commercial candi
This master thesis work consists of the development of new hardware and software for the control box of an azimuthal guidance system used by aircrafts during the approach to the runway. The thesis work was done at Safegate International AB as a project running along the usual development projects. When designing electronics to be used on an airfield there are a lot of regulations and standards t
Total resection of glioblastoma multiform (GBM), the most common and aggressive malignant brain tumor, continues to be a challenge. Achieving complete resection is limited by difficulty in intraoperative discrimination between normal and residual tumor cells. This project contributes to the development and evaluation of a fiber-optical based fluorescence/reflectance spectroscopy system as an intra
Ambiguity and controversy abounds the debate over the thousands of people trying to enter the European territory and their rights, especially in their procedural form. This paper explores the latest developments in the context of the European Court of Human Rights’ and the European Court of Justice’s expansive interpretation of the right to an effective remedy and the procedural guarantees afforde
Rhinosinusitis is the fifth most common diagnosis for which antibiotics are prescribed- but it is often done in vain. Currently, the only way to fully determine whether or not such treatment is actually needed is an invasive procedure. In order to spare patients from the discomfort that it would involve, this essential step is often skipped and instead, antibiotics are prescribed regardless. Using
Wind power developments in cold and icing conditions pose new challenges to the wind power industry. Icing of wind turbines cause safety hazards, production losses and increased loads. This means that there is a need to develop a technique to quantify the icing climatology and corresponding eects on wind turbines to enable large scale wind power developments in the windy, sparesly populated areas
This research proposes that an interdisciplinary approach to understanding the concept of culture and culture change could be beneficial for Sustainable Development. It explores the transferability of the DIKT Learning Model and theory of Creative Populations, originally found in management literature, and applies them to a social change corporation in Medellin, Colombia. The corporation analyzed
Design of a concrete column with biaxial moments and normal force is unpractical without the aid of a computer program. It is very time consuming to go through all calculations and to find a suitable layout of a cross-section and positioning of reinforcement for the final design. The goal of this thesis is to create a user friendly computer program for this problem. A critical pier in the Öland B
Aortic valve stenosis is a common congenital heart defect among children. In affected patients, the normal tricuspid valve structure is malformed into a bicuspid valve structure due to a fusion at one commissure. A common treatment is transcatheter balloon valvuloplasty, where a balloon is inserted through the aortic valve and inflated to mechanically tear the fused region, restoring a tricuspid s
How can we understand Gällivare municipality as a sacrifice zone through local narratives of green transition? The transition to low-carbon economies in the wake of the European Green Deal drives increased demands for metals and minerals, renewable energy, biomass from forests – intensifying green extractivism. In Gällivare municipality, located in the rural north of Sweden and within the borders
Introduction Illicit maritime activities frequently involve "dark" vessels that disable or manipulate their Automatic Identification System (AIS) signals to evade detection. This study evaluates the effectiveness of Synthetic Aperture Radar (SAR) and Optical imagery for vessel detection using both “manual” and automated Deep Learning (DL) methods while integrating AIS data to validate, i
Received Signal Strength Indicator (RSSI) circuits are critical in modern Wi-Fi receivers, playing a key role in power management and protecting the radio frequency (RF) front-end from saturation and potential damage. This thesis presents the design and evaluation of a novel rectifier circuit conceptualized for use in an RSSI system within an industry-standard 22nm CMOS node, specifically targetin
