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

Kunskap om markens uppbyggnad är viktig både för konstruktions och prospekteringsändamål. Geofysiska undersökningsmetoder kan användas för att skapa en överblick att basera vidare undersökningar på. I den här studien används likströms resistivitet och inducerad polarisation, IP. Datan är inverterad med en Cole-Cole modell i programmet ÅrhusInv och använd för att karakterisera berggrunden vid ÖnnesFor both construction and exploration purposes, knowledge of the subsurface is important. Geophysical exploration methods can be used to acquire an overview of an area on which further investigations can be based. In this study direct current resistivity and induced polarization data, inverted with a Cole-Cole model in program AarhusInv, are used to characterize the bedrock at Önneslöv in Scania,

The purpose of this thesis is to determine how electric vehicle trucks can meet the needs of customers in the urban building and construction sector. This sector contributes significantly to greenhouse gas (GHG) emissions, and also creates noise and other disturbances in urban environments. There are multiple benefits that come with electric trucks, which can address these issues if they are used

Förenta Nationernas fredsbevarande operationer har under nästan två decennier besvärats av anklagelser om sexuellt utnyttjande av och sexuella övergrepp på civilbefolkningar. Flera rapporter visar inte bara att organisationens fredsbevarande styrkor begår dessa brott mot just de människor de fått i uppdrag att beskydda, utan också att de undgår ansvar och straff. Denna uppsats undersöker och utvärUnited Nations peacekeeping operations have, for the better part of two decades, been plagued by allegations of sexual exploitation and abuse of local civilian populations. Several reports indicate not only that peacekeepers exploit and abuse the very people they were sent to protect, but also that these crimes routinely go unpunished. This thesis examines and evaluates the different methods of ho

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 research was conducted to determine which areas in the Robat Turk watershed in Iran are sensitive to gully erosion, and to define the relationship between gully erosion and geo-environmental factors by two data mining techniques, namely, Random Forest (RF) and k-Nearest Neighbors (KNN). First, 242 gully locations we determined in field surveys and mapped in ArcGIS software. Then, twelve gully

Light extinction is widely used to study particles in sprays, soot-forming combustion, and multiphase reactive flows. However, quantitative interpretation of extinction signals remains challenging when particles have a sufficiently large scattering albedo, meaning that incident photons are scattered much more than they are absorbed. This is especially true when experiments involve large apertures

Currently, the legal provisions and the administrative practice of the European Patent Organization, the EPO, concerning the patentability of computer-implemented inventions are ambiguous and unclear. The contracting states to the EPO have all reproduced the legal framework, the European Patent Convention, into national law but the administrative practices of the national courts has led to a diver
