During the past 20 years, the price of forest estates in Sweden has raised more than the price of timber. The purpose of this study is to investigate if it, despite this development, is possible to buy a forest estate based on economic grounds. Different forest parameters will also be studied to analyse their effect on the profitability. The study is done in cooperation with the company LRF Konsult. Purchase price of 34 forest estates near the coast of Norrbotten, Sweden, has been compared to yield valuation. For the valuation, guidelines from the Swedish author Lantmäteriet was used.

Automatic rumination measuring can be applied as a health indicator in dairy farming but is also highly desirable for research purposes. This study aimed to validate the technical functionality of the product RuminActTM, which employ acoustics to monitor rumination duration. The time budget of high yielding cows was studied and possible differences in rumination time between 13 rations were interpreted. Further the study examined what affects daily rumination and rumination efficiency. The validation was performed with direct observations that were compared to the automatically recorded rumination durations.

Forest biomass is becoming an increasingly important source of renewable energy, and thereby the demand is increasing. There is currently 213 000 km of forest roads in Sweden that could be suitable for biomass harvesting. Harvest of biomass along forest roads both provides biomass and maintains the quality of the roads. Currently, the volume of biomass along roads can only be assessed post harvest, chipping and industry deliverance. As the decision of whether or not to harvest should preferably be based on more than experience, the TJ-method has been proposed. The TJ-method is a subjective method to quickly determine the dry matter quantity with the assessment being conducted from the roadside.

Uppgiften är att utarbeta ett förslag på inriktning vid val av ett framtida markbaserat precisionsbekämpningssystem för den nya Försvarsmakten. Uppsatsen tar avstamp utifrån RMA, även kallad ?den nya krigföringen?, som antas vara den vision som gäller när det nya försvaret skall formas. Inledningsvis studeras de trender och pågående projekt som föreligger. Dessa får sedan lägga grunden för ett antal spelkort som bedöms utifrån de förväntade krav som kommer att ställas i framtiden.

Due to human influences on the climate an increase in Earth's mean temperature is today an accepted conception. With a rising temperature discussions have started how the climate in an area will change in the future. Equally interesting and important is it also to study the precipitation in an area. Precipitation is the factor, next to temperature, that affects most how a climate in an area looks like and feels. Since precipitation is connected to evaporation the latter parameter is also of interest to study.

Background: Various follow-up studies show that there are deficiencies in the care of patients affected by stroke. In order to provide good care according to the National Board of health and welfare and national guidelines for stroke care systematic quality audits need to be carried out.Purpose: To investigate if the local guidelines for stroke care in Örebro County are followed and to explore how people with stroke experience care and rehabilitation in hospital, primary care and community.Method: Primary health care records were reviewed using quality indicators in the local stroke guidelines. Samples of patients were obtained from the County´s three hospitals. Differences between men and women, younger and older, were analysed with chi-squared test. Eleven people were interviewed about their experiences of care, rehabilitation, support and participation.

The purpose of this study was to examine how commitment to a cause on a local basis had developed in four smaller groups during one decade. In 1996 I interviewed representatives in Åsele, Borrby, Hasslarp and Tving about their commitment and citizen initiative. Now, ten years later, I followed it up by interviewing them again. I wanted to know if the groups/associations still existed, if they had achieved their goals as they where pronounced ten years ago and how a strong commitment on a local basis can develop during ten years. Which phenomena decide whether the group develop or phase out? I use the term citizen commitment instead of citizen initiative to stress the fact that it is no longer an initiative but an on-going commitment.

Biogas is a renewable energy produced through anaerobic digestion, which means that organic matter is degraded by microorganisms under anaerobic conditions. The produced biogas can then be used for cogeneration, electricity, heat or upgraded to vehicle gas. Eskilstuna Energy & Environment AB has four digesters at Ekeby water sewage treatment plant, Eskilstuna. One of the biogas reactor (RK4) is equipped with a jet-mixing system while the remaining digester uses top-mixing. The mixing system is an important parameter to achieve optimum operating conditions for the process regarding gas production and degree of digestion.

Research shows that almost 30 per cent men and 20 per cent women at the age of 16-24 inSweden download music on a regular basis instead of buying records. Thanks to moderntechnologies teenagers of today have become used to downloading music illegally from theInternet. Even though legal alternatives, such as Spotify, have become popular, the behaviorof illegal download of music still persists. What do record companies do to prevent thisphenomenon and why do they go to such length to stop this widespread movement? Thequestion is, why is illegal download of music a problem ? and for whom?To investigate this I?ve read books about the subject, analyzed web pages of alternative recordcompanies and interviewed a drummer in a local band.

Det finns olika strategier och många olika metoder inom strategierna för att tidsuppskatta ett IT-projekt. Dessa strategier och metoder skiljer sig mer eller mindre åt och många gånger har företag egna metoder för tidsuppskattning. Dessa strategier och metoder har samma syfte, vilket är att göra så noggranna tidsuppskattningar som möjligt för att undvika försenade projekt. Examensarbetets syfte är att visa på hur LexiConsult AB kan förbättra sina tidsuppskattningar av inkommande IT-projekt genom att följa studiens rekommendationer, vilket leder till bättre tidsuppskattningar och nöjdare kunder. Undersökningen har utförts genom en litteraturstudie, där genomgång av de olika delarna inom IT-projekt skett.

Roughly 130 000 dwellings have been officially registered since Norway as of summer 2009 passed their bill ?Energimerkeforskriften? on energy performance certificates in buildings. The main objective is to decrease the total amount of national energy consumption by producing a methodology of calculation of the integrated energy performance of buildings as well as proposing cost effective measures to lower each building?s energy consumption. As the measures should not contravene nor be incompatible with the intended quality and character of the building, the ?Energimerkeforskriften? exempts buildings that due to their historical and cultural values are protected cultural heritage legislation. The current system offers a couple of professional certification alternatives, but when two online semi-automatic methods developed specifically for non-professionals are by far the most used, and since the methods of calculation primarily have focused on modern building materials and construction, the rest of the historical building stock stands literally unprotected by incorrect performance certificates and high-risk energy efficient measures. The objective of this thesis is to identify if the current Norwegian energy certificate system poses a threat to older buildings.

Unmanned aerial vehicles (UAV?s) are nowadays greatly appreciated. The advantage over manned airplanes are great since UAV?s can be much smaller and therefore lighter. The goal of this project is to evaluate the performance of an environmentally friendly UAV using only lithium-ion batteries.

Through participant observation in a local promoter group of hardcore punk shows inGothenburg and qualitative interviews with its members I have investigated links between taste in music, values and social structures in the hardcore punk scene. The theoretical framework of this essay is built upon the concept of subcultural capital, which is adapted from Pierre Bourdieu and developed by Sarah Thornton and Keith Kahn-Harris. The result shows how members among the hardcore punk scene create and preserve distinction towards others, while the distinction becomes important benchmarks for including and excluding practices in the scene..

Syfte: Syftet med denna studie var att undersöka om det finns några skillnader i den ackommodativa responsen när den fastställs med tre olika mätmetoder. De utvalda metoderna för denna studie var dynamisk retinoskopi i form av Nott och Monocular Estimation Method (MEM) samt en COAS-HD VR aberrometer.Metod: 29 personer (7 män och 22 kvinnor) deltog i studien, vars medelålder var 23,6 ± 3,1 år. På varje enskild patient gjordes en subjektiv refraktion med en efterföljande mätning av dess ackommodativa respons med tre olika mätmetoder på ett 40 centimeters arbetsavstånd. Resultaten av studien analyserades med hjälp av Repeated Measures-ANOVA och ett post-hoc test i form av Sidak´s. Överensstämmelsen mellan metoderna redovisades därefter visuellt i form av ett Bland-Altman plot.Resultat: Det visade sig att alla tre metoder gav liknande värden på den ackommodativa responsen, vilket resulterade i att det inte fanns en statistiskt signifikant skillnad mellan metoderna (p = 0,1103) enligt Repeated Measures-ANOVA.
