Hypervelocity stars (HVSs) are stars located in the Galactic halo travelling with extremely high speeds. They are produced when a binary approches the supermassive black hole (SMBH) in the Galactic Center (GC) and gets tidally broken up. In this process one of the stars is ejected with high velocity. The angle between the velocity of the incoming binary and the velocity of the ejected HVS is alm
Background and objectives: Type 2 diabetes has been increasing all over the world. A healthy diet, including particular functional foods is an effective strategy to prevent this form of diabetes. Nopal (Oputia ficus) is a cactus plant that, according to traditional medicine, has antidiabetic properties. The objective of this research was to examine the effects of different fractions of nopal clado
Denna uppsats är en kvalitativ aktionsstudie som genom intervjuer undersöker hur lärare och elever på ett estetiskt program resonerar kring och definierar begreppet “personligt uttryck” samt vad de tänker ska utföras för att uppfylla kunskapskravet innehållande begreppet. Detta i syfte att öka kunskapen i huruvida samsyn råder eller inte, öka förståelsen kring hur eleverna definierar och resonerarThis essay is a qualitative action study that through interviews studies how teachers and students in an aesthetics program in highschool defines and thinks about the term “personal expression” and what the student should do to meet the expectations for fulfilling the requirements concerning that particular grade. The purpose is to increase the knowledge about what differences and similarities the
More and more structural analyses today are being conducted with computer-based tools in comparison to traditional methods using hand calculations. The development, according to the Norweigan scientist Kolbein Bell is shifting from using first order analyses with correction factors, to using second order analyses, with computer-based tools. This dissertation mainly compares analyses of glulam colu
In this study calorimetric measurements provided evidence of a drastic increase of spinach leaf gross metabolism as a consequence of vacuum impregnation (VI) at a minimum pressure of 150 mbar with trehalose and sucrose isotonic solutions. When applying VI extracellular air is replaced by the impregnation solution, potentially limiting tissue respiration to any remaining air volume in the tissue. H
Data on net CO2 exchange from eight forests in Denmark, Sweden, Finland and Iceland were used to analyse which factors were controlling photosynthesis and respiration. The forests consisted of different species ranging in climatic condition from temperate to subarctic. Only well mixed conditions were analysed (u* > 0.3 m s(-1)). The parameters of a light response function showed strong seasonal va
2D resistivity modelling was done in order to examine the imaging resolution of 4 different configurations for mapping of fracture zones in bedrock. The studied arrays include Dipole-dipole, Gradient, Pole-dipole and Wenner. A variety of geological models were tested and the imaging possibilities and limitations of the different arrays were analysed. Apart from imaging fracture zones with various
The main aim of this paper is to study land-atmosphere exchange of carbon dioxide (CO2) for semi-arid savanna ecosystems of the Sahel region and its response to climatic and environmental change. A subsidiary aim is to study and quantify the seasonal dynamics in light use efficiency (epsilon) being a key variable in scaling carbon fluxes from ground observations using earth observation data. The n
The resting spores of Plasmodiophora brassicae, causal agent of clubroot disease of crucifers, are tolerant structures with the abitity to survive for at least 15 years in soil waiting for a host. The influence of incorporation of cut grass (Lolium perenne) and presence of the earthworm Aporrectodea caliginosa on R brassicae resting spores was investigated in a microcosm experiment, and measured a
This master’s thesis is about public libraries and how the work they do for children and youth in the summer holidays relates to public policy and reading research. Triangulation of methods is used with literature review, policy analysis, questionnaire survey and interviews. My primary theoretical framework is Carol Bacchi’s ’What’s the problem represented to be’ (WPR) approach, which is also us
Many of our cities have problems with air pollution and it have been shown to cause a lot of damage to human health. There are different kinds of air pollution, some are gaseous air pollutions like NOx or ground-level ozone and other air pollutions are particles. NOx forms in high temperatures from combustion processes like in a car motor. Ground-level ozone form in combination with NOx, hydrocarb
Diabetes is a chronic disease that affects lots of people all around the world. It greatly impacts the health of those with it and places many demands on healthcare services. Early detection of diabetes can significantly improve treatment outcomes, lower the chances of future health issues, and help patients to have a better healthier life. In this study, I evaluated the reproducibility of the per
The purpose of this thesis is to examine the views of internet stakeholders in Sweden, from the perspective of net neutrality. There does not exist one single definition of the principle, which makes defining net neutrality in the context of this thesis important. The basic concept of net neutrality is that all similar internet content should be treated equally. However there are several technical
Hearing is our second most important sense. The main focus of a surveillance camera is obviously the video but the audio shouldn't be neglected. It is possible to hear what the camera can't see and what is said in a conversation can't be showed in a video. Therefore there are good reasons to always try and achieve the best audio possible. This is not an easy task since cameras are oper
All people, regardless of gender, are entitled to participate in cultural life. 41% of the permanent actors and actresses at the Royal Dramatic Theater in Stockholm are women. Only 34% of the Malmö Theater roles in 2009 went to actresses. There is a male norm, not only in Swedish society, but also in the Swedish theater. How does this norm look like and what methods are required to change it? Eve
Denna studie intresserar sig för när en organisations förtroende sätts på spel. Kriskommunikation är i fokus och mer specifikt hur modejätten NA-KD har hanterat ett försök till bojkott, vilket kan kopplas till det aktuella fenomenet cancel culture. Studiens primära syfte handlar om att öka förståelsen för hur organisationer som utsätts för en liknande kris online kan hantera dessa med hjälp av resThis study is interested in when an organization's trust is exposed. Crisis communication is in focus and more specifically how the fashion giant NA-KD has handled an attempt to boycott, which can be linked to the current phenomenon of cancel culture. The primary purpose of the study is to increase the understanding of how organizations that are exposed to a similar crisis online can handle th
The famous problem of Canadian Literature in the contemporary critical landscape is how it, as an institution, denies all but certain kinds of identities. Alexander Beecroft suggests that a national literature, through its attempts to locate and articulate a communal identity and a notion of fellow-feeling, curates characteristics among members of previously numerous groups which can function to d
Centralt för uppsatsen är Leo-lagen som tillkom efter en företagsskandal på 1980-talet där ledande befattningshavare i AB Leo fått teckna aktier i bolaget till fördelaktiga villkor. Leo-lagen som nu återfinns i 16 kap. ABL stadgar att ett beslut om nyemission måste fattas av bolagsstämman med minst nio tiondelars majoritet om de som ska ha rätt att teckna aktier ingår i den av Leo-lagen utpekade fIn the centre of this paper is the 16 chapter of the Swedish Companies Act (Sw. aktiebolagslag (2005:551) (ABL)). The law was adopted after a big company scandal in Sweden during the 1980s where officials in the company where given shares at profitable terms. To prevent this scandal from occurring again the law states that a decision to issue new shares to officials has to be made at the annual sh
