This meta-analysis and systematic review examined the effects of psychedelic substances on death anxiety, specifically evaluating whether psychedelic experiences are associated with statistically significant reductions in death anxiety. Studies were eligible if they quantitatively assessed death anxiety or death acceptance using validated measures, or qualitatively explored attitudes toward death
This thesis explores the classification of savannah trees using EnMAP hyperspectral and Sentinel-2 multispectral satellite data using a Random Forest classifier. The study aimed to assess if the increase in spectral information from the hyperspectral data gives an increase in classification performance, to find the advantages and limitations to hyperspectral data compared to multispectral data and
Myoelectric prosthetics utilize machine learning(ML) algorithms to translate surface electromyography(sEMG) signal patterns into movement, allowing patients to easily control their prosthesis. While the use of conventional ML algorithms has been effective within these prosthetics, challenges still remain in terms of classification accuracy and computation speed. It was hypothesized that Kolmogorov
Nondestructive assaying (NDA) is an important step in ensuring the safe handling of spent nuclear fuel and radioactive waste. The assaying techniques require the use of ionizing radiation detectors to determine the activity of said fuel. One candidate detector for such use is the cerium-activated LaBr3 inorganic crystal scintillator. This scintillator offers excellent resolution, decay times and l
Sweden has in the past decade embarked on a journey to rebuild the concept of ‘total defence’. The crisis management system led by the Swedish Civil Contingency Agency has become all-the-more involved in the civil defense, with the Swedish Armed Forces responsible for military defense. The present thesis aims to explore the topic of gender and language in Sweden’s total defense discourse to uncove
Impact investing is a recently emerged field which aims to combine the goal of achieving financial returns with positive environmental or social impact. The documented loss of biodiversity has caused the emergence of many corporate environmental impact reporting frameworks, which have sometimes been criticized for their lack of biodiversity-outcome indicators. This study aims to take stock of the
The objective of this thesis is to investigate the feasibility of constructing temporary warehouse halls using glulam (glued laminated timber) frames, as well as to explore alternative solutions to PVC fabric for roofing and walls. The background is an increasing demand for temporary and flexible ware- house structures across several industries, along with a growing interest in environmentally fr
Deforestation is one of the most significant environmental challenges, with close links to global issues such as biodiversity loss and climate change. The European Union Deforestation-free Products Regulation (EUDR) introduces rigorous due diligence obligations for companies placing forest-risk commodities and derived products on the European market, intending to halt global deforestation. Despite
This thesis investigates the focusing performance and robustness of auto-focusing Airy beams in near-field wireless communication scenarios. Through a combination of simulations using MATLAB (Matrix Laboratory, a numerical computing environment) and full-wave electromagnetic simulations in FEKO (Feldberechnung für Körper mit beliebiger Oberfläche, an electromagnetic solver developed by Altair), th
Cell type deconvolution - the computational estimation of cellular composition in bulk tissue samples - is a valuable tool in cancer research for understanding immune infiltration and tissue heterogeneity. Most deconvolution algorithms infer the composition of cell types in bulk samples by modeling the observed expression data as a linear combination of reference expression profiles from each cell
Denna uppsats undersöker hur det tyska partiet Alternativ für Deutschland tillskriver nationell identitet i sitt språkbruk utifrån kapitel 12 Kultur und mediapolitk från deras valprogram inför valet 2025. från. Arbetet utgår från metoden textanalys där verktyget What s the problem represented to be av Carol Bacchi (2009) appliceras i analysen kombinerat med teoretisk forskning kring populism enlig
Bakgrund: Preoperativ ångest är vanligt förekommande inför kirurgiska ingrepp och anestesi. Ångest kan bottna i brist på information, oro för kirurgi/anestesi, komplikationer eller rädslan att dö. Hög preoperativ ångest är kopplad till negativa effekter, såsom: ökat behov av anestesimedel, instabilare vitalparametrar, mer postoperativ smärta och illamående, samt sämre återhämtning och sårläkning. Background: Preoperative anxiety is commonly experienced prior to surgical procedures and anesthesia. This anxiety may stem from a lack of information, concerns about the surgery or anesthesia, potential complications, or the fear of death. High levels of preoperative anxiety are associated with negative outcomes, such as increased need for anesthetic agents, less stable vital signs, more postoper
This study aims to create a greater understanding of how public librarians in Sweden perceive target groups of easy-to-read books for adults and how they work to mediate those books to the different groups. To investigate these questions, I have conducted interviews with seven librarians at four public libraries in Sweden and analysed the results using the classification theory of Bowker and Star
Household expenditure patterns in Ukraine were explored with a focus on clustering techniques to uncover socioeconomic insights and inform policy interventions. Using an officially published Household Income Survey dataset for 2021, the research applies advanced machine learning models, including k-means, DBSCAN, and PCA, to analyze spending habits and identify household profiles with distinct exp
Title: TAKT Production System for Assembly (including material supply) of Crushing Equipment at Sandvik Problem formulation: A major part of Sandvik’s production system is driven by forecasting. While this method provides a structured approach for anticipating future demand, it introduces several operational challenges that disrupt the capacity of the equipment assembly line and flexibility. Thes
This thesis critically examines the Swedish ‘Security Zones’ legislation, the associated governmental discourse on organised criminality, and their implications for equality and racial justice. Through a critical discourse analysis, the thesis illustrates how the extended discretion afforded through the legislation facilitates law enforcement’s capacity for racial profiling and discrimination. It
Problem Statement: Sandvik Rock Processing is in the need for a classification tool, which can help them improve their inventory management. Currently, there are problems with inefficiencies with deficit as well as excess in inventory. The new classification shall the basis for the differentiation of service levels and facilitate a shared view on items’ importance. Purpose: The purpose of this th
While Swedish politics actively develops crime prevention strategies, particularly targeting gang-related criminality, the role of schools in these strategies raises critical concerns. This thesis focuses on the legal obligation of principals to inform the police, which may help prevent, hinder, or detect criminal activity. Schools are increasingly positioned as arenas for policing and prevention,
Klimatförbättrad betong erbjuder en av byggsektorns mest tillgängliga vägar till minskade utsläpp. Utnyttjandet begränsas dock i praktiken mer av produktionsförhållanden och tradition än av materialet i sig. Betongproduktion står för en betydande del av de globala koldioxidutsläppen. Cement, en av de huvudsakliga komponenterna i betong, går delvis att ersätta med tillsatsmaterial som mald granuleCement production accounts for a significant share of global carbon dioxide emissions, which has made the development of climate-improved concrete a central concern for the construction industry. Replacing part of the cement with supplementary cementitious materials reduces the climate impact, but slows the development of early-age strength, an effect particularly pronounced at low temperatures.
