Lysande belysning? En komparativ sutdie mellan belysningsmöjligheter och rekommendationer
One part of preventive conservation is controlling the lighting in the exhibitions. As a first step we have to accept the fact that the very act of displaying objects is causing them damage, and because the trend is for everything to be open to the public view all the time, the aim is to minimize light exposure of exhibits.This essay will present lighting options and relate them to the current recommendations. I have put the emphasis upon describing which methods one can use to minimize the degradation of exhibits on display by eliminating UV- and IR-radiation and reducing the visible light. The intention with this essay is to investigate the current lighting options and compare these to the recommendations on lighting exhibitions.The selections of different lighting options such as LED-, halogen- and energysaving lamps were made based on avaibility. Thereafter I did two types of investigations.

Miljöstyrning i Riksbyggens ombyggnadsprocess med hjälp av Miljöbyggnad
How the renovation of the vast Swedish existing building stock with renovation needs will be performed is considered as decisive in order to achieve the target set by the Swedish government of reducing the energy use by 20 percent by 2020. Consequently, the challenge of the building sector consists in reducing the energy use in the existing building stock but at the same time ensuring that the indoor environmental quality is improved and the cultural values are maintained.So far, there have been a few renovation projects which strongly have reduced the energy use and at the same time have taken into account the environmental aspects and the cultural values. The main reasons are that there have been few incentives and a lack of routines in order to steer efficiently a ?sustainable renovation?.The participants in a Nordic project on sustainable renovation thought that it would be a strong advantage to link the concept of sustainable renovation to the Miljöbyggnad certification system. Indeed it is trusted by the Swedish building and construction sectors and can provide sustainability targets in order to steer renovation processes.The objective of the master thesis is to show how the Miljöbyggnad certification system could be integrated in practice in the renovation process of Riksbyggen, an organization which administers housing associations (Bostadsrättsföreningar) and build houses.
ENERGIANVÄNDING PÅ BYGGARBETSPLATSER : Analys av införandet av energieffektiva byggetableringar
This report is the final step in the Bachelor of Science program in Building Construction Engineering, Department of Engineering Sciences, Uppsala University.The purpose of this study is to highlight the difficulties and possibilities that could involve the introduction of new energy efficient technologies and changing work around this technology. This study focuses on energy use at a construction site or other temporary workplace where so-called portacabins are in place to address the need for temporary facilities.The method for obtaining knowledge on the subject was mainly interviews with site managers working in Svevia AB's various activities. In conjunction with the interviews I visited construction sites and portacabins if it was possible.My most important suggestion to Svevia AB concerns a better organization in order to make poratacabins more efficient on energy and costs. The company should also evaluate and monitor the energy efficient portacabins that are in operation.Expected energy savings of new technology may not materialize if there are gaps in information, education, technical services and technical maintenance. It is very important to utilize the experiences of new technology.
Framgång både på och utanför fotbollsplan : En benchmarking studie om AC Milans intäktsmöjligheter
As the football industry develops into a highly competitive commercialized industry, football clubs must step up and improve their business strategy. This study focuses on the famous Italian club AC Milan, a club with many international titles but with declining revenues. The purpose of this thesis is to study how AC Milan can generate higher revenues by comparing its marketing and business strategy with the most profitable clubs in the world, the benchmarking partners Real Madrid and Manchester United. By using a benchmarking model, following the five steps of this process, conducting observation studies, an interview and examining secondhand information, gaps between the clubs were evaluated and analyzed. These evaluations became together with chosen theoretical references, the basis for the improvement suggestions and conclusions shown by the authors.
När gymkultur blir problematisk : En kvalitativ studie om ohälsosamt träningsbeteende
Gyms are populated by more and more people and there is an increased interest in wellness and health. However, there is a downside to the culture that people choose to step into. Exercise can go too far and take unhealthy directions. The purpose of this study is to examine how norms are created in the gym culture and how unhealthy behaviour is reproduced inside the walls of the gym. We have also done research about how a local gym identifies and handles deviant behaviour such as the use of doping and eating disorders.
Flykten från sig själv i jakten på jaget : Klivet in och klivet ut ur medberoendets gastkramande famn
Uppsatsen syftar dels till att försöka nå en djupare kunskap om medberoende som begrepp men undersöker även hur medberoendet kan förstås samt förklaras från en medberoendes eget perspektiv. Vidare undersöks också på vilket sätt tolvstegsprogrammet kan förstås som en fungerande behandlingsmetod för medberoende, varför samtliga intervjupersoner aktivt deltar samt verkar i en tolvstegsgemenskap för anhöriga till missbrukare. Studiens resultat presenterar olika typer av uttryck samt symptom som verkar framträdande för medberoende och knyter även an dessa till dels varandra och dels till varför samt hur tolvstegsprogrammet kan verka förebyggande mot dessa. Slutligen diskuteras även hur medberoende samt tillfrisknandet i tolvstegsprogrammet kan förklaras med hjälp av anknytningsteorin samt en sociokulturell teori om ett relationellt själv..

Bergförankrat vindkraftverk : Dimensioneringsprocessen för staglängder
Detta examensarbete har gjorts i syfte att få fram förankringslängder till ett bergförankrat vindkraftverk.Målet med examensarbetet har varit att få fram längder på förankringstag och en prövning av flera olika stagvarianter har gjorts.Det dimensionerande momentet och egentyngden på vindkraftverket har tagits från ett tidigare projekt beläget i Solberg. Dessa krafter har fördelats ut till stagen och förankringslängder har tagits fram. De delar som har hanterats i rapporten utöver dimensioneringen är stagvarianter, borrning av stag, injekteringsbruk och provdragning. En bottenplatta i form av en oktogon har använts i dimensioneringsprocessen. Stagen har placerats i en cirkulär form i ett lager.
Uljabuouda vindkraftpark turbinmodellering och stabilitetsanalys
This master thesis has been performed at Solvina in Gothenburg for Skellefteå Kraftand Vattenfall Eldistribution. The aim of it is to investigate the consequences of theinstallation of a wind power plant on the mountain Uljabuouda in the vicinity ofArjeplog. Especially the impacts on voltage and transient stability are examined.Furthermore, the amount of extra strain on the voltage regulation equipment and theneeds for increased regulation capabilities are looked into.The wind power plant is planned to be built by Skellefteå Kraft and connected to a130 kV grid owned by Vattenfall Eldistribution. The work comprehends the followingmain parts:- Theoretical studies aimed at wind turbines and power system stability issues.- Modelling of the type of wind turbines assumed to be built on Uljabuouda.- Simulations of different operation cases and analysis of the simulation results.The results from the simulations show that, as far as voltage stability and extraworkload on tap-changers are concerned, the wind power plant does not, in anysignificant manner, worsen the present conditions. The problem of overloading theline between Arvidsjaur and Vargfors is also minor.
