Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of various stream sections along the river length of 269 km. The total area of stream habitats was estimated to 647 ha of which 396 ha (61%) were considered as either potential or optimal juvenile nursery habitats. The area of these two habitat classes were used to estimate the smolt production in the river by using electro fishing densities of juveniles (0+ per 100 m2).

The increasing threat of climate change has led to a increased need for models to predict future climat. In these models the changes in the soil carbon pools due to changes in microbiel degradation of the organic matter can lead to both positive and negative feedback-effects. There is however a lack of consensues on the temperature respons on degradation soil organic matter. This paper aim to give a better understanding on the factors controlling the temperature respons. The factors studied were the carbon substrate qualitity and the physiological status of the microorganisms.

This paper studies the relationship between individual characteristics of displaced workers and the probability of re-employment. A competing risks hazard model is used, distinguishing between exits from joblessness to self-employment and to paid-employment. All individuals between 25 and 55 years of age, at the time of displacement, that suffered from at least one year of joblessness after being displaced between 1990 and 1998 due to establishment closures that occurred between 1990 and 2001 are included. This allows for the closure procedure to be between one and three years long. Each individual is followed, from the year of displacement until the year of re-employment or at the latest, ten years after displacement.

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.

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.

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.

SammanfattningBakgrund: Varje dag används vitala parametrar inom vården för att bedöma en patients tillstånd. Användingen och tolkningen av de vitala parametrarna påverkas av kunskapen och erfarenheten hos sjukvårdspersonalen. Patientens säkerhet och lidande påverkas av användningen av vitala parametrarinom vården.Syftet var att beskriva användningen av vitala parametrar inom vården.Metod: En systematisk litteraturstudie genomfördes. Sex kvalitativa artiklar och en mixed method granskades med Willman et al. (2011) granskningmall.

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.

In today´s forestry, assessments of needs for thinning are based on basal area measurements. This is an indirect measurement. The approach and the developed assessment tables are based on an assumed production forest, which implies that management proposals in stands that deviate from the basic model may be misleading. Since Walter Bitterlich in 1948 launched the idea of the relascope, several modifications have been developed for different purposes. In common is that all are based on a certain angle measurement principle.
