Popular Abstract in Swedish Kemi finns överallt omkring oss, både i vår omgivning såväl som inuti oss. Vi kanske inte alltid tänker på det, men kemiska processer påverkar oss dagligen och är en förutsättning för vår existens. Det kanske därför inte är så konstigt att människan alltid varit intresserad och fascinerad av just kemi. Ämnet kemi används dock inte bara för att förstå kemiska processer iA considerable part of all chemistry in nature and in industry occurs in solvents. Sol- vents affect both the interactions and the reactions of the particles immersed in them. The work in this thesis concerns the properties of ionic and polar solvents, as well as the interactions between solutes and/or dispersed particles. Molecular simulations and simple approximate theories were used to study th

In this paper, I shall present and discuss some possible criteria of narrativity with regard to their applicability to pictorial objects. More specifically, I will argue that pictorial works may express or imply fictional narrative structures. First, as I would like to argue, the concepts of fiction and narrativity could and should more thoroughly be investigated with regard to other media, such a

The aim of this paper is to provide a cohesive categorisation of the most common sustainability assessment tools within the broader objective of lifting the understanding of tools from the environmentally-focused realm to that of the wider concept of sustainability. The framework provided is based on four main categories: indicators/indices, regional material and energy flows, life cycle approach

Certain climatologically-adverse conditions in the basin of the Poopo Lake, located on the high plateau of the Bolivian Altiplano, have prevented the existence of a reliable agricultural system and the impact on the population of the area has been severe. These problems have been the main motivation in choosing this region for this particular study. However, many species of plants have somehow man

Popular Abstract in Swedish Energibalansen vid jordytan är av avgörande betydelse för Jordens alla ekosystem men när det gäller Arktiska och sub-Arktiska ekosystem är kunskapen bristfällig. I dynamiska system som klimatsystemet, påverkas utbytet av energi, vatten och växthusgaser av små förändringar i ekosystemen. Syftet med denna avhandling är därför att skapa ökad kunskap och en tydligare bild aThe surface energy balance determines the functioning of any ecosystem on the Earth but is still poorly understood in Arctic and subarctic biomes. In a dynamic system, such as the Earth’s climate, any change in its characteristics modifies the exchange of energy, water, and greenhouse gases between the surface and the atmosphere. Therefore, this thesis aims to draw a conclusive picture of the surf
