Modelling the formation of super-km-sized planetesimals by gravitational collapse of regions overdense in small particles requires numerical algorithms capable of handling simultaneously hydrodynamics, particle dynamics and particle collisions. While the initial phases of radial contraction are dictated by drag forces and gravity, particle collisions become gradually more significant as filaments

Czechoslovak productive efficiency of the iron and steel sector fluctuated below the energy efficiency frontier. Until early 1970s, the country's iron sector was one of the least efficient ones in our sample. It was, however, during the decades of 1970s and 1980s that efficiency measures were adopted and the energy efficiency of the Czechoslovak iron and steel sector increased significantly to, de

Academic developers (ADs) often participate in the implementation of programs or reforms within higher education. Sometimes they agree with these and sometimes they disagree. This paper discusses possible agentic positions during an authentic policy implementation, i.e. the National Qualification Framework within a Norwegian university. Through reflexive interpretation, and by applying concepts f

Key stereoelectronic properties of Desulfovibrio desulfuricans [FeFe]-hydrogenase (DdH) were investigated by quantum mechanical description of its complete inorganic core, which includes a Fe6S6 active site (the H-cluster), as well as two ancillary Fe4S4 assemblies (the F and F' clusters). The partially oxidized, active-ready form of DdH is able to efficiently bind dihydrogen, thus starting H-2 ox

Microphthalmia-associated transcription factor (MITF) is a master regulator of melanocyte development and an important oncogene in melanoma. MITF heterodimeric assembly with related basic helix-loop-helix leucine zipper transcription factors is highly restricted, and its binding profile to cognate DNA sequences is distinct. Here, we determined the crystal structure of MITF in its apo conformation

The effect of different process stages on microstructural and visual properties of dark chocolate was studied. Samples were obtained at each phase of the manufacture process: mixing, prerefining, refining, conching, and tempering. A laser light diffraction technique and environmental scanning electron microscopy (ESEM) were used to study the particle size distribution (PSD) and to analyze modifica

The exothermic nature of oxidation causes nearly all semiconductor applications in various fields like electronics, medicine, photonics, and sensor technology to acquire an oxidized semiconductor surface part during the application manufacturing. The significance of understanding and controlling the atomic scale properties of oxidized semiconductor surfaces is expected to increase even further wit

Employee engagement has become more of an important issue for nonprofit organizations as they have to maintain an unprofitable social mission with often stringent resources. This study problematizes that most research about employee engagement is from a managerial approach, while research from the “communication constitutes organization” (CCO) perspective recognizes the close link between communic

This master thesis aims to explore the reception of refugee focused CSR communication in the form of audiovisual rhetoric on YouTube as well as analyze audience comments in a pursuit of identifying types of commenting behaviour that arise with the emergence of a commenting persona. Even though audiences play a major role in rhetoric, and has at times been explored theoretically in rhetoric litera

The thesis aimed to answer the research question: ‘What are the possible interventions measures to prevent child marriages in Nepal?’ by analyzing six in-depth semi structured interviews of people working for children’s rights. The earlier studies of child marriages and discussions of children and human rights has been used to analyse the data. Child marriage is a practice that occurs across regio

Over the past two decades several central banks have to varying extent and over different periods used unconventional monetary policy in order to govern stubbornly low inflation rates. As policy rates decrease to near zero or even negative levels for prolonged periods of time, the risk premium on financial markets as well as the cost of debt is altered. This thesis examines how equity valuations o

This thesis establishes an understanding of violence as discourse in the setting of Turkish prisons, during the death fast in the early 2000s. It uncovers discourses embedded in the acts of torture, hunger striking and force-feeding, each able to produce certain kinds of subjects. Investigating the interplay between power logics that underpin these violent practices, the thesis contests the idea o

To roll its dung-ball along straight paths across the African Savanna, the ball-rolling dung-beetle Kheper lamarcki (Mac Leay, 1821) utilizes a broad repertoire of celestial compass cues. These include the position of the sun and the polarization pattern that forms around it. It is hypothesized that a celestial snapshot of these cues needs to be stored in order to support orientation. However, it

Introduction The global prevalence of HIV is still increasing and the AIDS epidemic has become an endemic disease for the inhabitants of South Africa. UN states that AIDS was the second leading cause of death in adolescents, age 10-19 on a worldwide basis. Southern Africa has the most densely HIV inhabited countries in the world. In Sweden the incidence rate of HIV is 4.3 cases per 100,000 lived p

This thesis analyzes the effects of mountain tourism on local people and communities in Nepal with a focus on three main questions: the equity of mountain jobs, the impacts of Western mountaineering’s dominance on local cultures, and the respect and lack of respect for local workers' lives. Despite repeated accounts of precarious and dangerous working conditions the adventure and mountain tour

This study investigates the environmental impact from dog food and cat food produced in Sweden. With over 2.5 million dogs and cats in Sweden the potential environmental effect from their food is relevant to investigate. The aim of this study is therefore to quantify the environmental impact of 1 kg dog and cat food sold by Granngården. This has been done with the life cycle assessment (LCA) metho

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
