Projektering av vindkraft i turbulensintensiva områden : med fallstudie för Wallenstams planerade park vid Skuggetorp
Along with the rapid expansion of wind power in Sweden during the last decades the competition about favorable areas has hardened. This among other reasons has caused the projectors to look into development of wind power in forests. There are several aspects regarding fatigue loads on the constructions that are severe in complex terrain, among which turbulence is one. The levels of turbulence which are accepted in order for the turbines to face a life length exceeding 20 years are regulated by the International Electrotechnical Commission, (IEC). In order to keep the turbulence below these levels there are three major steering tools to use: The ambient turbulence decreases with height and can therefore be regulated by the hub height of the turbines.
Sedimentprovtagning av dagvattendammar som ett alternativ till flödesproportionell vattenprovtagning
Stormwater run-off from surfaces such as roads or rooftops is often polluted with heavy metals and nutrients. Many of these substances can cause great damage in biota if they end up in the recipient. In Sweden constructed wetlands and ponds for treatment of stormwater are frequently used, since research has shown that these treatment ponds are reducing stormwater pollution considerably to a low cost. The knowledge of these pollutant removal mechanisms and how follow-up and assessment of the ponds should be performed is still limited.To determine the pollutant removal efficiency of the stormwater ponds it is recommended that flow-weighted water samples are collected from both the inflow and the outflow of the pond. This method demands considerable resources of time and money for installations and analysis.
Lärplattformar : En fallstudie av lärplattformarna vid Umeå universitet
Umeå University currently uses two Course Management System, Moodle and Sakai (Cambro). Both Moodle and Sakai are based on open source code and are today the two more popular choices among Swedish Universities. They both have different strengths and weaknesses both from a technical perspective and a user perspective. This can create problems for a course responsible/teacher when it comes to planning the course structure at a distance course but also when planning the course structure on a campus course that uses a Course Management System. With this as my starting point my formulations of questions become:How do the Course Management Systems that Umeå University uses differs, both from a technical perspective and user perspective?What possibilities is there in the Course Management Systems to use a different Course Structure?Is there a noticeable difference on the view of Course Management System of teachers and students at different departments?The purpose with my essay is to create a basis that course responsible/teacher can use to plan the course structure.
Avveckla eller utveckla mjölkproduktion : vilka faktorer påverkar beslutet?
The decrease in the number of dairy farms in Sweden has been ongoing for a longer period of time. But the fact is that this has previously not had any big effects on total amount of milk produced in Sweden. The main reason is that the remaining dairy farms get larger. However, during the past year, there has been a decrease in the total amount of produced milk, because the decrease is faster than the increase within the farms that are left. During the same period of time the supply of milk on the global market also has decreased.
In spite of the fact that the global supply have decreased and the fact that the milk price increases, there are dairy farmers in Sweden who chose to exit the market.
?Vem behöver anledningar när man har heroin?? ? En kvalitativ studie om socialsekreterarens erfarenheter av motivationsarbete med heroinmissbrukare ur ett förändringsperspektiv.
The purpose of this essay was to examine the different aspects of motivational work with active heroin-using clients from a social workers point of view. The further purpose of this essay is to also examine what the advancements and discouraging factors in such a motivational work might be. To attain this purpose we focused on these following questions:What might motivational work with active heroin-using clients look like?According to the social worker, what factors constitutes for a beneficial progress in the engagement of motivational work with active heroin-using clients?According to the social worker, what constitutes for discouraging factors in the engagement of motivational work with active heroin-using clients?We chose to do a qualitative study by conducting separate interviews with six social workers working in a social services agency, all of whom are working with drug-addicted adults. We then analyzed the answers by using an abductive research strategy, testing the collected empirical data against our chosen theoretical perspectives.
Utvärdering av Naturvårdsverkets bedömningsgrunder för makrofyter i sjöar
According to the Water Framework Directive of the European Union, macrophytes should be used as indicators in the ecological and environmental monitoring of lakes. In the member state Sweden the Environmental Protection Agency has elaborated assessment criteria for determining lake status based on macrophytes. The main focus of this thesis is to evaluate the efficiency of the assessment criteria for macrophytes. In addition the concordance between the ecological status classes of the four quality factors included was analysed.The assessment criteria for macrophytes are based on the total phosphorus preference of the respective species. The focus is thus mainly on the nutrient level of the investigated lakes and the environmental problem monitored is eutrophication.
Energianvändning och energieffektiviseringsåtgärder vid sjukhusen i Norrbottens län
I Sverige finns det överlag ett stort intresse och god kunskap om miljöeffekter, men samtidigt saknas ofta insikt om energianvändningens inverkan på miljön. Många ifrågasätter inte tillgången på energi och tar därför inte hänsyn till kopplingen mellan energianvändning och miljöfrågor, trots att energieffektivisering är ett av de viktigaste sätten att förbättra miljön. Förvaltning utgör en stor del av en byggnads totala livscykelenergikostnad (LCCe). Norrbottens läns landsting är en stor fastighetsägare i Norrbotten med en total lokalyta på cirka 700 000 kvadratmeter, varför effektiv förvaltning är betydelsefull beträffande så väl ekonomi som miljö. Syftet med detta examensarbete är att kartlägga energianvändningen vid sjukhusen i Norrbottens län samt att identifiera möjligheter till effektivisering i energianvändningen.
Inköpsmetoder för prefabricerade betongstommar: Jämnförande studie av total och delad entreprenad
Anledning till studiens initiativtagande är att det inom området inköp av prefabricerade betongstommar saknas riktlinjer för hur alternativa entreprenadformer skall behandlas. I ett byggprojekt står stommen för cirka 15-25 % av totalkostnaden för ett byggprojekt. År 2008 köpte Skanska in prefabricerade betongstommar för en summa av 815 miljoner kronor. I 50 projekt uppgick stomkostnaderna över 10 miljoner kronor och stod för 71 % av totalkostnaden för det årets stominköp. Om entreprenadformen kan påverka resultatet så är det stora kostnader som kan minskas.
Ungdomars deltagande vid alternativa idrottsinsatser : Vilka deltar och varför?
This study's main objective was to identify adolescents participation in alternative sport activities and which kind of physical activity that was preferred by adolescents who didn't had any earlier experience of sport clubs. The study combined interviews and surveys with the purpose to get both adolescents and sport leaders perspective. A total of five interviews were performed and fifty-four surveys was collected. The results showed that adolescents already physical active were those who participated in alternative sport activities. Who participate in alternative sport activities can depend on habitus, comprehended capital forms and in which social field the sport activities exists..
Kvinnliga studenters alkoholvanor : På Linnéuniversitetet i Kalmar

The survey reveled that as many as 67%percent of the answering female students (according to Audit) have risky drinking habits.The drinking habits are explained using Albert Banduras social learning theory in contextto the Scandinavian drinking pattern. The study concludes that female alcohol habits needeven further research. Furthermore the study shows that student initiation have an impacton the female drinking habits and that expectations of that students drink are to some extentimportant to the development of hazardous drinking habits..
Factors affecting bark-stripping by red deer (Cervus elaphus) : the importance of landscape structure and forage availability
Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.

Jämförelse av två mätmetoder för mindre gasvolym
Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result.

Betydelsefull närhet och nödvändig distans : Sjuksköterskans professionella förhållningssätt inom palliativ vård
Palliativ vård innebär ett förhållningssätt där patientens livskvalitet står i centrum. Vården kännetecknas av en holistisk människosyn där patientens fysiska, psykiska, sociala samt existentiella behov ska tillgodoses. Från sjuksköterskans perspektiv kan palliativ vård bedrivas inom såväl primärvård som slutenvård och omfattningen av det palliativa vårdandet varierar beroende på inom vilket område sjuksköterskan är verksam. Oavsett kontext har sjuksköterskan en relationsskapande funktion och relationen har stor betydelse för patientens välbefinnande. Professionell hållning inom palliativ vård innebär att sjuksköterskan medvetet tillämpar ett empatiskt förhållningssätt.
