This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).

Syftet med den här uppsatsen är att studera vad som har påverkat spotpriset på el i Sverige mellan åren 1996 och 2002. För att besvara syftet har de variabler som påverkar utbudet respektive efterfrågan, och därmed också spotpriset på el, identifierats med hjälp av traditionell ekonomisk teori. Därefter har en modell utformats och lösts med hjälp av Two-Stage Least Square metoden. De inkluderade variablerna i modellen är disponibel inkomst, pris på olja, teknologisk utveckling, kapacitet samt importerad kvantitet el. Förklaringsgraden på regressionen blev cirka 82 procent vilket tyder på att det kan finnas variabler som påverkar spotpriset på el som utelämnats från modellen.

ABSTRACTThis thesis contains a partial edition of a previously unpublished manuscript, De lapidibus et gemmis (MH 59, Lund University Library). The manuscript was probably written in the late XVth century and consists of five parts. Part 1 (ff 1r-1v) and 2 (ff 2r-14r) are written in Latin, part 3 (ff 14v), which is probably later than the rest of manuscript (XVI century?), in German, part 4 (ff 18r-33r) in Latin (some smaller passages in Swedish), part 5 (ff 34r-34v) in Latin and Swedish. The manuscript was written by at least two hands, probably more.I have chosen to examine and edit part 2, ff 2r-14r, which I have identified as a partial transcript of the franciscan Bartholomeus Anglicus encyclopedic work De proprietatibusrerum, probably written between 1230 and 1260.

Storage of biomass is associated with problems like heat development, biomasslosses, and reduction of the fuel quality. Certain processes such as biological- andchemical degradation are responsible for these storage problems. This master?sthesis was carried out at Vattenfall Research and Development AB and is alignedtowards quantifying the biomass losses from short-term storage (1-2 months) ofbark and recovered wood. The biomass was stored in outdoor piles during differentseasons, campaign 1 (summer) and campaign 2 (autumn).

During late autumn/winter in the years of 2005/2006 and 2006/2007 a questionnaire study was made in Västra Götaland county in the south west of Sweden. Inspectors responsible of animal welfare answered the questionnaires during their routine visits to different horse stables in the county. The questionnaires contained questions about the number of horses at the farm, hoof condition, body condition, how often the horses were fed outside and the pasture condition. The purpose of this study was to investigate if a connection could be seen between environmental factors and health factors within the horses in this material. The connections that were analysed were between; hoof health and pasture condition, how many times the horses were fed outside and the body condition and between the number of horses in the pasture and pasture condition.

Titel: Växelkursprognoser för 2000-talet Ämne/kurs: NEKK01, Examensarbete C, 15 högskolepoäng Författare: Kenth Hedberg Handledare: Thomas Elger och Fredrik NG Andersson Nyckelord: Sverige, nominella växelkurser, prognoser, UIP Syfte: Syftet med uppsatsen är att fylla tomrummet av att det bara finns ettfåtal svenska studier för 2000-talet. Uppsatsen kommer att belysa hurden nominella växelkursen ska prognostiseras för att matcha defaktiska värdena på bästa sätt. Metod: Tillvägagångssättet för denna uppsats är att skapa prognoser utifråntre olika prognosmetoder som sedan jämförs med de faktiska värdenaav den nominella växelkursen. Det bestäms sedan utifrån treutvärderingskriterierna vilken metod som därefter ger det bästautfallet. Slutsats: Visar att AR(1) och AR(1) med ränta prognostiserar bättre än randomwalk med en kortsiktig prognoshorisont.

Uppsatsen undersöker med användande av rangsummetest om LPM-modellen är mer lämplig än riskmått baserade på varians och systematiska riskmått baserade på CAPM för analys och urval av svenska hedgefonder under perioden 1996 - april 2001..

This investigation?s task was to map manufacturing of special qualities at Stora Enso Packaging under a certain period, analyze if rules concerning special qualities is followed, which consequences this results in concerning use of paper, waste and costs and to give suggestions on alternative solutions. The goal was to give sugges-tions that help the company to reach its business ratio that the production de-partment uses within use of paper and productivity in the corrugated cardboard machine.Stora Enso Packaging is a part of the forest group Stora Enso and is one of Swe-den?s leading producers of corrugated cardboard. Stora Enso Packaging acts pri-mary on the Swedish market, where they have a market share of 25 %.To be able to analyze orders with special qualities we did a data collection during two months, where we mapped incoming orders.

Enligt vår teoretiska referensram samt enligt en undersökning som genomfördes åt Statensoffentliga utredninger, (SOU 1997:188), kan ett samband mellan motionsutövande och hälsapåvisas. Det finns däremot ingen entydig forskning som visar på att motionsutövande leder tillminskad sjukfrånvaro. Vår studie utgår från grundhypotesen att det finns ett positivt sambandmellan företagssubventionerad friskvård och minskad sjukfrånvaro. Genom enenkätundersökning där 48 ICA-butiker medverkade samt där butikernas årsredovisningargranskades, insamlades data relaterad till butikernas friskvårdssubventionering ochsjukfrånvaro. Enligt ett Chi-square test kunde ett svagt samband mellanfriskvårdssubventionering och sjukfrånvaro skönjas, och även beräkningarna för korrelationenmellan de två variablerna för den insamlade datamängden påvisade ett samband.Nyttjandegraden av friskvårdsbidraget visade sig vara högst vid en subventioneringsnivå på3000 kr per år och anställd, och uppgick vid nämnda nivå till i genomsnitt 30 procent.

The thermal response of a borehole field is often described by non?dimensional response factors called gfunctions.The g?function was firstly generated as a numerical solution based on SBM (Superposition BoreholeModel). An analytical approach, the FLS (Finite Line Source), is also accepted for generating the g?function. In thiswork the potential to numerically produce g?functions is studied for circular borehole fields using the commercialsoftware COMSOL.

Finnhamn is a small group of islands in the Stockholm archipelago. At Stora Jolpan, the biggest island, there is a hostel. The main building was built in 1915 and is called Utsikten. The purpose of this project is to on behalf of the Archipelago Foundation (Skärgårdsstiftelsen) find alternative systems that can replace the existing heating system of Utsikten (an oil-fired boiler and electricity heaters) to a system with renewable energy. The alternative system that this project focuses on is a system of solar collectors combined with a wood chip boiler.

Varje studie av en verklig process eller ett verkligt system är baserat på mätdata. Förr var den tillgängliga datamängden vid undersökningar ytterst begränsad, men med dagens teknik är mätdata betydligt mer lättillgängligt. Från att tidigare enbart haft få och ofta osammanhängande mätningar för någon enstaka variabel, till att ha många och så gott som kontinuerliga mätningar på ett större antal variabler. Detta förändrar möjligheterna att förstå och beskriva processer avsevärt.Multivariat analys används ofta när stora datamängder med många variabler utvärderas. I det här projektet har de multivariata analysmetoderna PCA (principalkomponentanalys) och PLS (Partial Least Squares projection to latent structures) använts på data över avloppsvatten insamlat på Hammarby Sjöstadsverk.På reningsverken ställs idag allt hårdare krav från samhället för att de ska minska sin miljöpåverkan.

The relatively poor economy in European dairy farming might be improved from efficient feeding systems and dietary management. Increasing herd sizes and transition to loose housing systems in Sweden, increases the possibilities for other feeding systems than separate feeding that is the traditional feeding system in Sweden. Other possible feeding systems are partial mixed ration (PMR) and total mixed ration (TMR), where the TMR system sometimes is associated with overfeeding and thereby increased environmental impact and high feed cost. Diets providing nutrients above or below animal requirements are considered as unbalanced, which in turn are associated with reductions in health, fertility and milk production. On the other hand, a balanced feed ration improves feed efficiency, nitrogen utilization and profitability.

Passive houses are a relatively new concept in Sweden and by that it is meant a house without a traditional heating system. The most acknowledged passive house project is the terrace houses in Lindås, Gothenburg, which we have used as a reference. This project concerns a square apartment block. So far, no square apartment block has been built as a passive house in Sweden.The common opinion in the construction industry is that it is not economical to build extremely energy efficient houses. With Peab as commissioner our task was to investigate if that is true, if regarding the construction of a multi storey house as a passive houseMidroc, now owned by Peab, constructed in the block of Preussen in Jönköping during 2004-2005 four houses, with 132 apartments distributed on seven floors.

A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.
