The course contains amongst others: an overview of the different phases of the evolution of a star, the magnitude system and using it for stellar astronomy, the equations of stellar structure, nuclear reactions in stars, energy transport via radiation and convection, stellar evolution using analytic stellar models, and

Kursen ska ge förutsättningar för att dels kunna välja lämpliga komponenter för olika tillämpningar inom optoelektronik och optisk kommunikation, dels kunna arbeta med utveckling av nästa generation komponenter. För att uppnå detta läggs stor vikt vid såväl den bakomliggande fysiken som vid hur prestanda påverkas av komponentdesign och materialval.The course will provide a platform both for the selection of suitable devices for various applications in optoelectronics and optical communication and for the development of next generation devices. In order to achieve this, the course will emphasize the underlying physics as well as how performance is affected by device design and materials properties.

Homelessness as a political and social dominion has a number of features that make it particularly difficult to tackle. In addition to being a wicked problem, homelessness offers several analytical avenues. How do these characteristics affect the evaluation of programmes and projects aspiring to combat homelessness? Dissimilar pictures and solutions regarding homelessness in the US and in European

Detta examensarbete utvärderar ett absorptionshämmande tillsatsmedel för att möjliggöra användningen av krävande ballast vid betongtillverkning. Den huvudsakliga anledningen till att ballasten benämns som krävande är att den har ovanligt hög absorptionsförmåga. Studien undersöker hur betongens egenskaper påverkas av olika halter absorptionshämmare. Dels studerades glimmerrikt bergkrossmaterial, soThis master thesis evaluates an absorption-inhibiting admixture to enable the use of demanding aggregate materials in concrete production. This was achieved by investigating how the properties of concrete were affected by different levels of absorption inhibitor. Firstly, mica-rich aggre-gate material was studied, which, due to its high mica mineral content, has a high water absorption rate that i

This thesis examines youth attitudes toward the gender-system and the believed causes of gender roles: biology or social factors. The study has been designed as a survey conducted among 116 Swedish 9th graders, where the students had to classify weather stereotype roles and tasks are more natural for one sex than the other, or both. By comparing the answers of the pupils with respect to their own

In the United States of America media and the press have the important role of being ”the fourth estate of government” which means that American media has the task to examine the political processes taking place within the country, as well as the USA's actions abroad. The importance of media not being biased or not framing certain kind of information cannot be overemphasized, but despite this,

Populärvetenskaplig sammanfattning Kartering av makrofyter, framtagandet av en klassificeringsmetod för att kunna beräkna ekologisk status för Ålands skärgård och skapandet av miljöövervakningsprogram Europeiska unionen har i sitt miljöarbete bestämt att varje medlemsland ska upprätta övervakningsprogram och klassificeringsmetoder för att övervaka miljöns ekologiska status. Varje medlemsland anAbstract This mater project was conducted in Åland by assignment by the Government of Åland Islands. The project consisted of two parts, one survey of macrophytes and classification of the ecological status and a proposal on a marine monitoring program. The survey of macrophytes was conducted in the late summer of 2012, by SCUBA divers along 50 meters long transect at twelve sites in the Åland ar

This article takes a selection of works of contemporary photography as starting points in a discussion about globalised movements, connections, and conflicts. The aim of the article is two-fold; first, to bring out and analyze how contemporary photography today finds new strategies with which to engage with aspects of the phenomenon of globalisation, and second, to contribute to a beginning tenden

This study aims to highlight conditions for some selected non-profit organizations providing social services in Toronto, Canada. The essay is a case study which includes literature studies, field observations and interviews with respondents working in the non-profit sector. The analyses are mainly based on qualitative semi structured interviews with respondents working in non-profit organizations

The planetary boundaries (PBs) framework defines a "safe operating space" based on nine key Earth system processes. Out of these, four are terrestrial, and their primary driver of transgression is agriculture. To better understand how agricultural activities might further influence the terrestrial PBs, it is essential to model their drivers and interactions over time. A helpful tool for
