A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.

Denna rapport utreder huruvida feedforwardreglering av ventilationssystemet på Kiruna flygplats leder till lägre energianvändning. Rapporten jämför ett feedforwardreglerat system simulerat i Simulink med ett feedbacksystem som motsvarar det existerande systemet på Kiruna flygplats. Jämförelsen görs på fläktens energianvändning och rapporten använder sedan energianvändning för värme och kyla för att avgöra huruvida systemet är ekonomiskt gångbart. Systemet är tänkt att kunna användas i alla miljöer med kända störningar i avseende till tid och storlek som till exempel flygplatser, biosalonger, teatrar och så vidare.Rapporten ger en kort teoretisk bakgrund till hur ventilationskrav, reglerteknik, feedforwardreglering och feedbackreglering fungerar för att sedan gå vidare till att redogöra för de förutsättningar som gäller för Kiruna flygplats med avseende på klimatskalets täthet, rummens volymer och utformning och drifttiden för ventilationssystemet. Med hjälp av simuleringar i Simulink görs en jämförelse av energianvändning då de båda systemen är optimerade utan att för den sakens skull kompromissa med kvalitén på inomhusmiljön.

Aspen (Populus tremula L.) and goat willow (Salix caprea L.) are two important tree species in the aspect of nature conservation. Due to the elimination of forest fires, a former negative attitude towards deciduous trees in forestry and a strong herbivore pressure, these tree species have been negatively affected during the last fifty years. The aim of this study was to investigate whether the occurrence of aspen and goat willow could be related to either human impact or to site properties, such as ground moisture and vegetation type. A side study included an inventory of a number of cyanobacterial tree lichens on aspen and goat willow in order to try to relate the occurrence of these lichens species to stand history and stand properties. The study was performed in Hamra State Forest in northern Dalarna. Nature reserves were compared with stands in managed areas.

African swine fever, ASF, was first described 1921, in Kenya. The virus has thereafter spread through many African countries as well as in Europe, Asia, South- and Central America. The virus is spread via three different cycles, of which one is sylvatic and includes warthogs and soft ticks. The other two are between domestic pigs and the one most common one is caused by humans, who not always realize the seriousness of precautions. The infection manifests as hemorrhagic fever, but can also be more or less unnoticed. The aim of this study was to use molecular tools to detect and partly genetically characterize ASFV both in soft ticks and in serum from domestic pigs in Uganda. Comparing viruses detected in ticks with those detected in domestic pigs I also wanted to investigate possible links between the sylvatic and domestic cycle.

Myofasciella triggerpunkter (MTrP) är ett relativt vanligt problem hos befolkningen. Det största problemet för de drabbade är smärta men det kan även orsaka rörelseinskränkningar samt ge refererad smärta. Diagnosen ställs enligt Simon och Travell utifrån ett antal olika diagnoskriterier, så som palperbara knölar i muskulaturen och ökad känslighet på och runt dessa. Sjukgymnastiska smärtreducerande behandlingsmetoder kan delas upp i invasiva- eller icke invasiva metoder. Syfte: Syftet var att genom en systematisk litteratursammanställning kartlägga evidensen för olika smärtreducerande sjukgymnastiska behandlingsmetoder vid MTrP i nacke, skuldra och ländrygg.

Our aim is to create a greater understanding for how Växjö Municipality is working with their vision, strategy and brand, and also how it is perceived by the business sector. This understanding will help us to highlight success factors and pitfalls that exist in the creation, implementation, and maintenance of a municipality?s identity, image and profile to convince the business sector to follow.Methodology: We have been using an abductive and qualitative research-method in which semi-structured interviews have been the basis of our empirical material. We had interviews with three employees, a communication manager and the mayor at Växjö Municipality as well as four organizations and two companies with sustainable focus. We did this to get different perspectives and thereby get a greater understanding.Analysis & conclusion: We have been able to identify both success factors and pitfalls in Växjö Municipality's strategic sustainability work.

Latvia has been an independent state twice, the first time during the years 1918-1940 and the second time from the year 1991 and ahead. During these two periods Latvia has been a destination for tourists. The aim of this study is to describe how Latvia as a destination has developed during the years of independence. One further aim is to compare what Latvia?s tourism industry looked like during the same periods to descry similarities and differences.

POUR (postoperativ urinretention) är en välkänd komplikation efter operation och incidensen för POUR varierar i olika studier mellan 0,5 % till 70 %. Det framkommer också att patienten kan ha POUR redan innan operationen startar. Felaktig behandling av POUR kan bli orsak till blåsuttänjning, urinvägsinfektion och kateterrelaterade komplikationer. Därför är det viktigt att det finns ett evidensbaserat förhållningssätt för att förebygga och behandla POUR under pre-, per- och postoperativa perioden. Syftet med studien var göra en sammanställning av befintlig kunskap när det gäller riskfaktorer för att utveckla urinretention efter elektiv operation.

This thesis aims to show the positive effects of marketing by studying whether the regulation on direct marketing to consumers of prescription drugs today prevents to consumers accurate information and better health, and how consumers relate to the possible legalization of increased marketing through controlled and information audited webpages. Methods used in this research are qualitative method, quantitative method, documents and websites studies. The thesis fulfills the purpose as it shows the potential positive effects of an expanded marketing through pre-approved websites. It also shows a demand from the consumers' side and a need for increased awareness for more empowerment over their own health.

Renewable energy and the charging of electrical vehicles will increase in the future. Therefore the risk of outages is also increasing, partly because renewable energy is intermittent and the production amount can change fast. Charging electrical vehicles is often demanding high effect in short time, which could make faults occur. It takes more advanced technology to short the outage time. Today Övik Energi has high reliability in the power grid, but in order to maintain the reliability, it is time to prevent problems that can occur in the future. This thesis has presented a suggestion for the placement of fault detectors Protrol IPS2, in which a total of four detectors is proposed.

Swedish healthcare has experienced increased economic pressure during the last decades and organizations have faced many changes. Managers and their roles in organizations have also been affected by the changes. Traditionally, managers in the healthcare sector are highly specialized doctors with a strong medical background. In the thesis, we study a big private healthcare company with an ambition to lead the development in the sector. In order to accomplish its goal, the company is trying to change the organization of managers.

The aim of this Masters thesis is to, from a users perspective, investigate which factors affect the library use for six persons with disabilities or visual handicaps. My method has been a case study and the methods applied are interviews and observation. As a theoretical framework I use Tom Wilsons theories and models about information behaviour and transform them to a model about library use. Answers are sought to the following questions: - What does the library use look like for six persons with disabilities or visually handicaps? - How do they experience the library in their own municipality? - Which factors affect the disabled persons library use and experience of the library? All interviewees showed a very positive attitude towards the library and the majority of them visited the library regularly or received audio books by mail.

This report investigates what attitude private forest owners in the County of Stockholm, Sweden have towards biodiversity landconservation. Private landowners were asked to answer a questionnaire containing questions about there property and there attitude towards biodiversity. The results show that private landowners attitude towards biodiversity is affected by, amongst other things, the size of their property; a larger property have a more negative owner than a smaller property. A landowner that lives on his property has a more negative attitude towards biodiversity than a landowner that?s not living on his property.
