Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.

The purpose with the paper is to theoretically investigate how sensory experience and positive affect in contact with outdoor environment can promote health by 1) develop a model of the sensory and emotional processes based on multiple code theory (Bucci, 1997) and 2) examine if this model can increase understanding of the processes that takes place in outdoor recreation, the way this is described in environmental psychology research and theory. The paper starts by introducing research and perspectives concerning outdoor recreation. Different theories of nature?s health promoting effects are described. These include the restoration theories of Roger Ulrich and Steven and Rachel Kaplan, theories more concerned with outdoor activities and a theory combining these two perspectives called instorative theory. After this sensory and emotional information processing is examined through the works of Wilma Bucci and Jean Ayres. Antionio Damasio?s theories of emotion and Daniel Stern?s concept of vitalityaffects are than introduced to extend this reasoning.

In 2022, Russia completed its full-scale invasion of Ukraine. The EU responded with powerful restrictive measures against Russia to demonstrate its unified support for Ukraine, indicating that the perception of Russia as an external threat to the EU, particularly in Central and Eastern Europe (CEE), has become increasingly evident following the invasion. Drawing on theory and previous research suggesting that external threats strengthen group identities, I argue that Russia is perceived as an external threat to EU identity in CEE after Russia's invasion of Ukraine. Stephan and Stephan's integrated threat theory considers an external threat as either realistic, posing a threat to the ingroup's existence, or symbolic, posing a threat to the ingroup's worldview. The purpose of this study is to examine the relationship between EU identity and the perception of Russia as a group threat to the EU among individuals in CEE based on the nature of the group threat: realistic and symbolic.

Vid MS och ALS förekommer depressioner i olika nyanser, vilket är viktigt försjuksköterskan att fånga upp tidigt och ge den omvårdnad individen behöver samt att minska lidandet. För att detta skall kunna uppnås är det viktigt att den som är sjuk känner trygghet och tillit i sin relation till sjuksköterskan. Syftet med studien var att beskriva människors upplevelser av olika symtom i samband med depression som förekommer vid MS och ALS. För att fånga upp människors upplevelser av symtom i samband med depression användes en kvalitativ metod. Data samlades in genom åtta självbiografier som var skrivna på svenska av både kvinnor och män.

This pilot study describes a therapy method for persons withBroca´s aphasia. This method is based on the mapping hypothesis (Schwartz,Saffran & Marin 1980). The mapping hypothesis is based on the assumptionthat agrammatism is caused by an inability to combine syntactic structurewith thematic roles. This study describes a combination of the therapymethod mentioned above and the Everyday life activities photo series (ELA,Stark 1992). The aim of the study was to investigate if therapy based on awritten sentence/picture format is a viable starting-point for future research.The therapy presented combined written sentences with pictures describingeveryday life activities.

The aim of this study was to examine which research had been done on dietary supplements for dogs suffering from osteoarthrosis. The main questions the author wanted answers to were ?Is there evidence in the research that dietary supplements for dogs with osteoarthritis have effect in such a way that quality of life is increased in these animals??, ?are there any contraindications regarding dietary supplements?, ?who is responsible for the control of safety on dietary supplements for dogs in Sweden? and ?what kind of advice would I give to dogowners about dietary supplements?. To be able to answer these questions the author conducted a literature study of the recent research on dietary supplements for OA in dogs. The results showed that despite the lack of research in this field, some promising research has been done on multiple different supplements.

For some time, there has been a general thought that churches built in the Early Middle Ages in Scandinavia, around the 12th century, directly replaced cult buildings or cult sites from the Late Iron Age. There are archaeologists who have criticized this and were instead skeptical that churches at all were built on places where a pre-Christian cult building existed. Several examples from Scandinavia contradict this and show a continuity of place and cult from the Late Iron Age to the Early Middle Ages. The aim of this thesis is through a spatial analysis, study Late Iron Age archaeological sites in the landscape around thirteen churches located around lake T?kern in the western part of ?sterg?tland, to see if there is a place and cult continuity from the Late Iron Age to the Early Middle Ages at the selected locations.

The work that is the basis of this Master Thesis was performed on Scania´s group of cabdevelopment, and concerns the GPS-system in Scania´s trucks. Today, the GPS-systemconsists of an active antenna mounted on the roof of the truck. The antenna is connectedto the receiver with a coaxial cable.The purpose with this Master Thesis was to develop and evaluate a new GPS-system,where the information is distributed using a LIN-network. Today, each unit requiringGPS-information is equipped with its own antenna and receiver. This solution has beenthe most cost effective to this point.

Syftet med denna studie var att beskriva erfarenheter som personer med multipel skleros (MS) har av förändrad delaktighet och om deltagande i temagrupp kan främja delaktighet i aktivitet. Undersökningsgruppen bestod av två män och två kvinnor som hade haft MS i minst ett år och hade upplevt förändringar i sina vardagliga aktiviteter. Fokusgruppsintervjuer användes som datainsamlingsmetod och genomfördes vid två tillfällen under deltagarnas rehabiliteringsperiod. Individuella uppföljningsintervjuer genomfördes en månad efter deltagarnas hemkomst. Analys av insamlat material resulterade i tre kategorier som gavs namnen: Förändrad delaktighet i vardagen, Lärdomar som influerar vardagen och Skapandet av en ny vardag.

Vad är val? Är de val vi har våra egna? Spelutvecklare idag kämpar med spelares fria vilja då detta kan orsaka problem. Till exempel när spelare gör val som spelutvecklare inte har räknat med, vilket som följd kan skapa frustration hos båda parter. Problemet med spelares oförutsägbarhet i sina val är något som spelutvecklare ständigt har försökt lösa. Idag finns det flera tekniker som syftar till att diskret manipulera möjligheten till val inom spel och samtidigt låta spelare vara ovetande om detta.

My essay is an attempt to describe how complicated it can be to follow the rules and maintain boundaries without obstructing the children in their creative development. The aim is to highlight my approach and emphasize the importance of growing up in a kindergarten with standards and values which may not always coincide with their own opinion.I begin my essay with two stories about Emil five years, defying the rule of not climb up the climbing frame roof and Emma for three years, who are keen to spin on the swing, but followour rule and refrain. I wonder what it is that drives some kids to go against the rules and stretch the limits while others do not have any problem doing that we decided? I also tell about the time I as a newly-qualified nanny was rebuked by a colleague when I acted "recklessly". I would handle the situation differently today? In the last story, I praise a child for being "mischievous", which makes me proud.
