This paper studies the ideas of two actors in the Scandinavian field of Information Systems development. It analyzes the writings of Börje Langefors and Bo Dahlbom in the 1980s and 1990s, and focuses on their collaboration resulting in the publication of Langefors’ Essays on Infology. Langefors was at that time honored as the founder of the information systems discipline in Scandinavia, but had al
The Sahel lies in the semi-arid zone of North Africa between the Sahara Desert to the north and the savannas and rainforest to the south. In the Sahel, the variability of vegetation growth is predominately controlled by moisture reception in the concurrent rainy season. The inter-annual variability of normalized difference vegetation index (NDVI) during the rainy season (April to August) can be ex
Deposition of ferroelectric hafnium zirconium oxide (HZO) on semiconductor samples with Atomic Layer Deposition (ALD) has proven to be a viable method of production. But while the physical processes of ALD deposition is relatively well know, there exists some gaps in knowledge about different parameters for the ALD and the resulting depositions. This work is about analysing mainly how the purge ti
In Europe, there are still a significant amount of residential fires. Particularly fires in the living room are a major threat to the occupants. Much research has been done to residential fires. However, there is still little known about the impact of the development of building structures and building content on the fire behaviour and room conditions. This report shows a clear view of how these d

In our everyday life we live distant from the origin of life itself - nature. Dramatic landscape and fascinating views touch us in a way that few other things manage to do. It is something that make us recognize our powerlessness and the feeling of awe towards the nature. Experiencing striking nature is a way to create a deeper understanding of our own world and at the same time enrich our lives w
Rhizosphere interactions have high influence on the fluxes of carbon to and from terrestrial ecosystems. One very important part of the rhizosphere interactions is the rhizosphere priming effect (RPE) which is defined as changes in the decomposition rate of soil organic matter (SOM) in response to labile organic carbon input from plant roots. Changes in decomposition of SOM affect nutrient availab

We live in a time where there is an increasing focus on the environment, in terms of classification of vehicle emission standards and environmental zones. Along with this and the fierce market competition that exists, it is odd that a greater effort has not been made in making material-transport more effective by renewing the tarmac on our road-network. The purpose of this report is to show the sa
This thesis investigates the feasibility of integrating Powdered Activated Carbon (PAC) in to chemical treatment in combination with disc filtration of tertiary wastewater. Jar and tube tests have been performed, where the suspension was filtered through a 10 μm disc filter from Hydrotech Veolia Water Technologies. The effluent has been analyzed for total phosphorus (TP), total suspended solids (T
The Jordanian state apparatus is increasingly limiting civil society in Jordan from engaging in open debate, and organisations are gradually inhibited from executing their activities and events. These are the premises on which this research is based, and in exploring them several questions arise. How can civil society in Jordan be characterised and applied? What do these obstacles look like in pra

This is an ethnographic study on how refugees and policies on asylum and immigration was debated on Facebook in Sweden during the so called ‘refugee crisis’. This study analysed the relation between the Facebook debate, and the way news media framed the ‘refugee crisis’ during three months in which Swedish asylum policy changed drastically: September 2015, November 2015 and January 2016. In Septem
This mastert hesis has been done as a joint project between the Department of Automatic Control in Lund and Volvo Technological Development in Gothenburg. The thesis treats methods to handle nonlinearities in a throttle unit. Theapproach has been to first design a linear controller based on the results from system identification, and then to develop an adaptive updating law estimating uncertain pa
En fredsprocess i Syrien måste garantera trygghet och säkerhet för alla, vilket inte minst inne-bär att ta i beaktande de särskilda säkerhetshot som kvinnor står inför i egenskap av att vara kvinnor. Denna undersökning kommer att granska FNs säkerhetsråds resolutioner och Action Group for Syrias och International Syria Support Groups fredsplaner från 2015 och 2016 som har till syfte att skapa fred
De svenska reglerna om principalansvar trädde i kraft 1972, när en ny skadeståndslag antogs av Riksdagen. Innan denna tidpunkt hade regler om principalansvar utvecklats i rättspraxis, men omfattningen av detta ansvar hade varit väldigt begränsad. I de flesta fall hade en arbetsgivare inte kunnat hållas ansvarig för de skador som hans anställda vållat i tjänsten. När regler om principalansvar into
Den 1 juli 2018 trädde den nya förvaltningslagen (2017:900) i kraft. I lagen ges enskilda, genom införandet av en dröjsmålstalan, för första gången i svensk förvaltningsrätt en generell rätt att föra talan mot förvaltningsmyndigheters passivitet. Om unionsrätten inte anger annat kommer den nya dröjsmålstalan, enligt principen om medlemsstaternas processuella autonomi, att tillämpas även vid förval
Background: In spare parts logistics, customers expect a high availability of spare parts from their providers. It is very critical for spare parts providers to be able to satisfy customers’ demands. It acts as a differentiator in the customer’s buying decision. Sandvik, an engineering company, is interested in improving their spare parts logistics. The case company is interested in benefits from
Nima is a distressed neighbourhood located north of central Accra, the capital city of Ghana in West Africa. Nima is an extremely dense community, where land is very scarce. Single floor, clay built compound houses occupy the entire neighbourhood. Spatial planning is lacking, infrastructure is limited and overcrowding proposes a severe problem. Nima, a neighbourhood which is a direct result of rap
