The demand for rare earth elements (REEs) is growing, while the future supply is uncertain. Their unique electronic characteristics make them irreplaceable, and the commercial value of pure fractions is high. A model-based simulation study is presented that compares batch chromatography with the twin-column MCSGP (multicolumn countercurrent solvent gradient purification) process for ion-exchange c

The current study empirically demonstrates the widely discussed gap between copyright law and social norms. Theoretically founded in the sociology of law, the study uses a well-defined concept of norms to quantitatively measure changes in the strength of social norms before and after the implementation of legislation. The ‘IPRED law’ was implemented in Sweden on 1 April 2009, as a result of the EU

Glucose levels 2 h after an oral glucose challenge are a clinical measure of glucose tolerance used in the diagnosis of type 2 diabetes. We report a meta-analysis of nine genome-wide association studies (n = 15,234 nondiabetic individuals) and a follow-up of 29 independent loci (n = 6,958-30,620). We identify variants at the GIPR locus associated with 2- h glucose level (rs10423928, beta (s.e.m.)

Objectives To describe clinical and ultrasound features of Brenner tumors of the ovary. Methods In this retrospective study, the databases of the International Ovarian Tumor Analysis (IOTA) studies and one tertiary center were searched to identify patients who had undergone an ultrasound scan before surgery for an adnexal mass that proved to be a Brenner tumor. Twenty-eight patients with 29 Brenne

This study examines the long-run impact of air pollution exposure at the month of birth and during pregnancy on labour outcomes in Germany. I match air pollution levels on a federal-state level to a longitudinal survey sample on individuals born in Germany. The study focuses on individuals born between 1985 to 1992, as this time period relates to consistent economic growth in Germany. The main ide

This master's thesis explores the use of unsupervised machine learning techniques to cluster countries based on their degree of human rights violations. Accordingly, the study evaluates the performance of two clustering methods, K-Means clustering and Latent Class Analysis (LCA), using two cluster validation metrics (Silhouette Coefficient and Dunn Index), as well as an Accuracy measure using

This bachelor’s thesis research focuses on information security. With the growing use of technology in research, information security has become an increasingly important concern for academic institutions, which face, among other, challenges related to the protection of sensitive data from unauthorised access, theft, and misuse. The research purpose was to explore the current information security

Online transactions, networking, also online shopping of goods & services have exponentially increased. Digital markets have been preferred by consumers, businesses. Undertakings are competing to persuade customers. Well established business groups gain dominant position in the market and more possibility to avoid new entrants, avoid competition. Conversely, new entrants face huge competition,

This study exploits the introduction of a new prioritization criteria for food security interventions to estimate the marginal impact of such programs. Findings indicate that, in municipalities assigned to receive nutrition policies more intensely, the number of children receiving micronutrient supplements was higher. In addition, being prioritized was associated with a very small improvement in n

This thesis will investigate how Erik Hobsbawm’s theory of ‘social banditry’ can be applied to a contemporary setting to explain the strength and workings of ethnic Albanian organised crime groups. The paper will delve into a pre-existing debate surrounding the effectiveness of this theoretical lens as a method to account for the global phenomenon of banditry (particularly in the feudalist age).

Colombia is advancing its mitigation and renewable energy policy instruments implementation. Specifically, the country has introduced support schemes for electricity generation from renewable energy sources (RES-E) and a national carbon tax. Therefore, these two instruments interact within the climate-energy policy mix. However, the interaction between them could be complementary or overlapping de

Right-wing populism has spread across the European continent during the 21th century, this paper examines if this also is the case on the social media platform Facebook. Through the use of multivariate ordinary linear regression models the thesis seeks to answer if right-wing populist parties and leaders in 12 western European countries generate more followers on their official Facebook accounts t

This thesis explores the functions of memory, collective identity, and communication of those same categories to the reader by means of the poetic form in Hanna Rajs’ poetry collection Under månen (2020). Situated or framed within a discussion on Holocaust Literature, Rajs’ poetry is considered in the light of a general historical purview of Holocaust writing, and her specific place within an auth

This essay investigates the effects of a same-sex teacher assignment on female and male 8th grade students in Australia and New Zealand using data from the Trends in Mathematics and Science Study (TIMSS). I employ the first difference (FD) method introduced by Dee (2007) to analyze the impacts on students' math and science academic achievements, as well as their attitudes toward these subjects

This text is an attempt to re-evaluate the significance of Roman imports in Scandinavian contexts as well as to answer overarching questions concerning frontier zones, and the building of core-periphery relationships. This is achieved by applying the Roman concepts of hospitium and dona militaria as well as theoretical frameworks such as provincial ritual practices and cultural hybridisation to a

The first aim of this project is to make high-order harmonic (HHG) setups more compact and user-friendly, by including a micro-channel plate (MCP). Simulations of the transmission properties of an MCP has been performed. These simulations displayed introduced structure in the far field, but a very well behaved beam in the near field. Further, the wavefront of the zeroth order diffraction spot of M

The aim of this study was to examine the relationship between authenticity and symptoms of anxiety and depression as well as health-related quality of life (HR-QoL) and life satisfaction in the context of the theoretically related constructs of adult romantic attachment, reflective functioning and insight in a convenience sample of Swedish adults. One hundred and ninety-one participants were recru
