This piece of work aims at gaining a better understanding of how cognitive and sensual experiences takes place when we interact within the social encounter processes of shared spaces. The structure of this thesis starts off with a theoretical review based on the aspects of social encounters divided into the following areas: affect theory, the ideal of sympathy, and situated multiplicity. These t
Timing of phenological events are highly related to climate and is one of the first signs of ecosystem responses to the climate change. Timing of flowering phenology is an important trait influencing the distribution and fitness of plants species. Tundra ecosystems are particularly important to study these effects due to short growing seasons, poor pollinator community and a particularly pronounce
BVOC emissions from trees contribute to ozone and secondary aerosol formation and therefore have an impact on air quality. The two most abundant BVOCs emitted from trees are isoprene and monoterpenes. In urban areas, air pollution levels are already elevated and high rates of isoprene and monoterpene emissions from trees will potentially contribute to even higher levels of ozone and aerosols in th
With the rapid and alarming rate at which forests are disappearing around the world, it is of great importance to effectively estimate loss of forest cover due to different causes. Among those causes illegal logging is a particularly enigmatic and dangerous one made well-known by the destruction of the tropical rainforests of South America and Southeast Asia. A less glamorous hotspot of illegal lo
Public participation during urban development is key for setting a project up for success and for supporting sustainable growth, but current detailed development plans available in paper-based 2D format are difficult for the public to understand. The literature has shown that the introduction of 3D visualizations can improve citizens’ understanding of a plan proposal; however, moving from static 2
The dynamics of molecules and electrons takes place on timescales of femtoseconds and attoseconds, respectively. This requires ultrashort and intense extreme ultraviolet (XUV) pulses to be able to study them. Two sources that can generate intense XUV pulses are free-electron lasers (FELs) based on self amplified spontaneous emission (SASE) and high-order harmonic generation (HHG)driven by intense
Reindeer (Rangifer tarandus) are the most common large herbivores in the arctic. With a habitat spreading over the entire circumpolar region, they can have a substantial effect on plant species composition and ecosystem processes and functions. They affect plant species composition by trampling, removal of foliage and by fertilization through dung and urine. These alterations in species compositio
Microswimmer is a term that denotes small selfpropelling agents, such as bacteria, algea or artificial robots. Depending on the flow field they set up they can be categorized into two classes: pushers (e.g. E. coli ) and pullers (e.g C. reinhardtii ). The occurrence of jets, eddies and flocking have been observed in systems of dens pusher suspension. This phenomenon is called active turbulence. Th
This paper analyzes the reactions of two forests, located in the same region, to drought conditions that occurred in 2018. Both locations experienced similar conditions including higher temperature and less precipitation than the previous four years. Both experienced drought that would be categorized as moderate according to standard precipitation index calculations and soil moisture values were v
This thesis focuses on the integration of management control system (MCS) and sustainability in companies. Some literatures showed a disconnection between the efficiency of sustainability as a success strategy and management control systems. To research this, we aim at answer two questions. What are the challenges that the companies were faced with when they tried to integrate MCS and sustainabili
The dissolved methane (CH₄) dynamics in pore water and nearby stream water were investigated in a subarctic peatland in West Greenland during summer and autumn in 2011. A pore water sampling method was used to collect samples at four depths (5-, 15-, 25- and 35-cm depth) in the fen site. Stream water samples were collected from 13 plots around the study site. The results from the field sampling in
Conventional agriculture in Sweden is facing challenges with low resilience to a changing climate and decreased biodiversity. Silvoarable agroforestry is an alternative land use practice that contain a woody perennial and crop in the same field. Trees on cultivated land break up large monocultures, increase biodiversity, creates functional diversity, and produces more commodities. This land use pr
Anthropogenic climate change has caused temperature increases all across the globe. Mountainous areas are among the most affected and are experiencing alarming rates of warming. Such rapid warming will have effects on alpine vegetation and their distribution throughout the alps. While there are many studies that have investigated shifting vegetation distribution around the world, none have found c
Vegetation in the subarctic is expected to respond to climate warming as its growth becomes less temperature limited. This has previously been recorded in the form of treeline advances and increasing shrub cover. Changes in vegetation cover may accelerate warming due to a decrease in summer albedo, in what is termed surface albedo feedback. A quantification of the relationship between vegetation c
It is estimated that the average Swede throws away 61 kg of food waste annually. The more food waste there is, the more food waste bags are required. Since the implementation of a tax on thin plastic bags, grocery stores have been providing fruit bags of paper as an eco-friendly alternative. This study examines the current usage of paper fruit bags in the municipality of Helsingborg and explores t
Aquaculture is an expanding industry, supplying closer to 50% of the total fish consumption. Commercialized fish production faces sustainability challenges which are important to address. Aquaponics uses wastewater from aquaculture to grow plants using hydroponics. This is a step towards making the industry more sustainable, but the practice is not straightforward. The plants and the fish thrive a
Glaciers and permafrost capture bacteria and viruses when they form, which can be suspended for millennia. This includes long since extinct pathogens which are functionally novel. As polar regions get warmer these pathogens will emerge and spread through the local ecosystem, potentially altering it. Ancient pathogens do not only pose a risk to their local environments as they can be aerosolized an
Climate issues are currently of attention in various contexts as changing climate factors affect us in many ways. One of these effects is the influence on the probability and frequency of fires, although other factors, especially anthropogenic ones, also play a role. In the Diyarbakir region, a Kurdish-Turkish province affected by the PKK's conflict (Partiya Karkerên Kurdistan - Kurdistan Work
Carbon storage capacity estimations of terrestrial vegetation are necessary to understand the limit of possible carbon emissions. General approximations, of a landscapes carbon pool capacity, can be performed using the InVEST-model. It estimates the carbon pool storage of a landscape, based on land use land cover classes, which this thesis aims to test on the highay-ancillary environment of th
