Tonvis av betong används på svenska byggen varje år. Detta trots att tillverkningen av en av huvudingrediensenserna - cement - ger stora mängder koldioxidutsläpp. Genom att ersätta en del av cementet med ett visst specialcement minskar koldioxidutsläppen samtidigt som betongen torkar fortare. För de flesta höghus som byggs i Sverige idag används betong som byggmaterial. Enorma mängder betong gårThis master thesis work concerns the effect of high-alumina additives on the selfdesication of concrete. The purpose of the work was to examine the possibilities to optimize the binder-content of concrete with regards to self-desiccation. Two highalumina additives have been examined. In the experiments 10% of the binder mass has been replaced with one of these additives. Commercially available ceme

This paper evaluates the profitability of adding green bonds to a portfolio consisting of stocks and conventional bonds. To determine the profitability, ten portfolios with varying weights on green bonds, conventional bonds and stocks, are constructed. The risk-adjusted returns on the portfolios are implemented in time series regressions of several asset pricing models, including the Capital Asset

Med ordet ’plast’ avses i vardagligt bruk typiskt helt eller delvis syntetiskt framställda polymerer (långa kedjor av upprepande mindre enheter), ofta tillverkade av ursprungligen fossilt råmaterial. Tack vare det stora omfång av önskvärda egenskaper som plaster generellt besitter, däribland uthållighet mot biologisk och kemisk nedbrytning samt låga produktionskostnader, har plaster blivit allstädThe many advantageous abilities of plastics have made them omnipresent in today’s society. However, the low cost of production, light weight, durability and insolubility in water combined with inadequate waste handling have led to a vast and increasing accumulation of plastics in nature, approximated to be over 6 300 million tons (Geyer, Jambeck and Law, 2017, ‘Production, use, and fate of all pla

The objective of this thesis was to investigate how double skin facades (DSFs) meet daylight and energy requirements compared to single skin facades (SSFs), also considering the life cycle costing (LLC) of both solutions. A South facing, an unobstructed glazed office building in Sweden was used as a basic building object, where SSFs and DSFs were iteratively applied. A mid-level floor was chosen a

Despite the issue of greywater management gaining more importance around the world, espe-cially in developing countries, it still remains a challenge in non-sewered areas of South Afri-ca. For a semi-arid country, reusing greywater on a household level has great potential as an alternative water source if done properly. On a household level, the popular repurposing of greywater is for irrigation

The world of creating new software is currently going more and more towards being as fast and agile as possible to be able to adapt to changing customer demands. The design process of new software should reflect that, which doesn't leave much time for scheduling user tests in person. How can feedback from users be gathered in a scalable way, and the design of a product be made using a fail-fas

En morfologisk analys av ett konstprojekt som bedrevs inom ramen för den ideella föreningen Ars & Modus verksamhet mellan 2004 – 2009. Utifrån analysen dras riktlinjer upp för en pedagogisk studie. Konstprojektet skrivs först in i ett större politiskt, ekonomiskt och konstnärligt sammanhang, där konstbegreppet utvecklas och problematiseras. Därefter belyses konstens alltmer instrumentella situA morphological analysis of an art project that was active during the years 2004 through 2009 within the framework of the NGO Ars & Modus. With this analysis as a starting point a study is then outlined. First the art project is put in a wider political, economic and artistic context and the concept ”art” is further developed and problematized. Then the growing instrumentalisation of art is hi

Problem Previous research suggests that it ought to be more challenging for social enterprise to manage its stakeholder relationships. It is assumed that a social enterprise in general both have a larger amount of stakeholders compared to regular enterprises, and that there is a larger divergence in values and interest among the stakeholders. Another layer of complexity is added if the social ente

Studiens syfte var att studera chefers uppfattningar och erfarenheter av funktionen rehabkoordinator och nyttan av den utbildning som rehabkoordinatorn har genomgått. Semistrukturerade intervjuer utfördes med tio chefer inom sjukvården. Datamaterialet analyserades med tematisk analys utifrån en induktiv ansats. Fyra teman urskildes: Räddaren i nöden, Funktionen som blev en person, Förändring tar tThe aim of the study was to investigate how health care service managers perceive and experience the newly introduced function rehabilitation coordinator and the effect of the education programme. A semi-structured interview guide was used to interview ten managers. The material was analysed with an inductive approach using thematic analysis. The following four themes were identified during analys

I ett framtida samhälle som inkluderar alltmer intermittent elproduktion och mindre svängmassa är det viktigt att hitta nya, snabba frekvensreglerande resurser för att bibehålla ett stabilt elsystem med säker energileverans. Ett exempel på en sådan resurs är batterier. En teknik som har fått alltmer uppmärksamhet de senaste åren är den så kallade ''Vehicle To Grid'' (V2G) teknologiIn a future society with an increasing amount of intermittent electricity production and lower inertia, it is important to find new, fast frequency-regulating resources to maintain a stable electrical system with a safe energy supply. One example of such a resource is batteries. A technology that has received increasing attention in recent years is the so-called ''Vehicle To Grid''

Biomedical application of nanoparticles is largely associated to their fate in biological media which, in fact, is related to their surface properties. Surface functionalitzation plays a key role in determining biodegradation, cytotoxicity and biodistribution through interactions which may be meditated by the macromolecules occurring in biological media. This project is focused on the effect of di

The presence of phytate in plants-based food is considered a threat to proper nutrition in developing countries and in particular in rural areas. There is evidence of micronutrient deficiencies due to the presence of phytate in plant-based diets. People from low income households are most affected by diets rich in phytate. The aim of this study was to investigate different processes through which

In the context of increasing focus on the climate change China is being blamed for its large contribution to global CO2 emissions, which have been produced within China’s territory. However, increasing number of researches have started to argue that the developed countries should be held responsible for displacing their emissions by outsourcing pollution-heavy production to the developing countrie

This study aims to investigate whether countries succeed to reduce their contribution to global emissions when countries reach higher levels of income. As a result of rapid changes in international trade, a country’s emission responsibility goes beyond national borders, which should be adequately captured in their carbon footprint. This study discusses that the two conventional accounting measures

På grund av människans aktiviteter har många av världens vattenresurser förorenats. Dricksvatten förorenat av arsenik, en tungmetall som kan orsaka akut förgiftning och en uppsjö av sjukdomar, blir allt vanligare världen över. I och med detta ökar behovet av sätt att detektera och oskadliggöra tungmetaller och även olika typer av skadliga kemikalier i våra vatten. Tänk dig ett system där bakteriMany of our freshwater resources are contaminated with pollutants such as heavy metals and organophosphates, and therefore the demand for reliable and efficient methods for detection and remediation of such pollutants is increasing. One widely used method for remediation of water is through the use of engineered communities of microbes that have the ability to degrade or make the contaminating com
