REDUCING CONSUMPTION OF TEXTILES

This report explains my degree project at Lund University School of Industrial Design. The project started out by exploring the materials Wood and Textile, although after researching the two areas further it seemed more valuable to look into the way we consume these materials today. We do not have unlimited natural resources, and yet we keep using them as if we do. I chose to reduce the project in

Politisk påföljdseftergift - straffmätning vid civil olydnad

Uppsatsen diskuterar hur civil olydnad som motiv för brottsbeskrivningsenlig gärning påverkar straffet för gärningen i det svenska rättssamhället. Efter att ha definierat begrepp och gått igenom den juridiska litteraturen kring civil olydnad ges en genomgång av tre domar vari Högsta Domstolen behandlar civil olydnad. Sammanfattningsvis nås slutsatsen att civil olydnad inte används i skärpande This essay discusses how civil disobedience as a motive for an illegal act influences the punishment for said act in the context of the Swedish criminal justice system. A definition of terms and an overview of civil disobedience in legal doctrine is followed by a study of three judgements wherein the Swedish Supreme Court treats the subject of the essay. The essay concludes in finding that the S

Aktiva åtgärder -inte tillräckligt aktiva? En undersökning av Region Skånes Likabehandlingsplan i ljuset av den svenska och den internationella lagstiftningen

Denna uppsats består av två delar. Den första delen behandlar vad som sker då en likabehandlingsplan på en offentlig myndighet, i detta fall Region Skåne, utökar rättigheter för persongrupper som inte är skyddade enligt lag. Den gör en utblick över internationell rätt och EU-rätt för att söka ytterligare ledning till hur rätten ser ut i ett vidare perspektiv. Då det inte är självklart vad som gäThis essay is divided into two parts. The issue discussed in the first part is what happens when a public authority, in this case Region Skåne, expands their equal treatment plan to cover grounds of discrimination not included in the Swedish Discrimination Act. It also provides an overview of international and EU laws regarding discrimination. The theories of jurist Wesley Newcomb Hohfeld are use

Impact of photo-chemical processing of dissolved organic carbon on the bacterial respiratory quotient in aquatic ecosystems

Inlandsvatten är globalt sett nettoutsläppare av koldioxid (CO2) till atmosfären. En stor del av den CO2 som produceras i akvatiska ekosystem kommer från baketrieplanktons mineralisering av löst organiskt kol via respiration (BR), där de tar upp syre (O2) från omgivningen och producerar CO2. Teknikerna för att mäta O2 konsumtionen är bättre utvecklade än de för att mäta CO2 produktionen. För att rDissolved organic carbon (DOC) enters inland waters from the surrounding terrestrial ecosystems, and is assimilated by bacterioplankton, mineralizing it to carbon dioxide (CO2). This bacterial respiration (BR) is an important part of carbon processing in freshwater, but it is also a process of global significance; in oceans and inland waters combined, BR is probably the largest single sink of orga
