To fulfill the climate target that EU and the Swedish government have decided to apply, it becomes increasingly important that the energy efficiency of existing buildings and making new buildings energy efficient as possible. Of Sweden?s total energy consumption in 2011 was 40% used by residential and service. Of the 40% of the energy consumption was 60% used for heating and domestic hot water. A report from year 2012 shows that one reason why the heating volume is so great could be due to underestimating on the energy consumption for the heating in the planning of the building.

Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

Filmskapare har unika hantverksmässiga kunskaper om hur man påverkar mänskliga kognitiva processer för att uppnå önskade effekter på åskådaren. Om dessa kunskaper blev systematiserade med hjälp av empirisk forskning, skulle de kunna komma till nytta även inom vetenskapliga discipliner där man intresserar sig för människans kognition.I denna uppsats kombineras analysen av två filmsekvenser med ett experiment i vilket åskådarnas ögonrörelser filmades och personerna fick svara på frågor om sina intryck av filmen. Resultaten tyder på att människor framför allt blir medvetna om sådana intryck som liknar verkligheten, t.ex. karaktärers personlighet och beteende, snarare än sådant som rör filmens form. Dessa fynd diskuteras i ett allmänt kognitivt perspektiv och ytterligare empiriska undersökningar föreslås för att studera samspelet mellan filmen och åskådaren.Summary in English:Through their craft, film artists have unique insights into methods of influencing human cognitive processes to achieve desired impact on the spectator.

The eutrophication of lakes and seas with the algal bloom and deficiency inoxygen that follow, has been given priority by the Swedish government as oneof 16 environmental objectives. The purpose of this project was to develop a toolbased on a simple model, limited amount of data and geographic informationsystem (GIS) to identify areas with risk for phosphorus losses due to surfacerunoff. This tool can act as a decision support to decide where appropriatemeasures should be applied with the aim of reducing phosphorus losses and bythat the eutrophication.The method that has been used is a combination of two models, one calculatingthe potential erosion while the other one identifies areas of erosion (net erosion)or deposition. This ability is of great importance because potential erosionshould be calculated on areas with net erosion. Areas with high potential erosionhave an increased risk for phosphorus losses due to surface runoff.The potential erosion was calculated based on factors which describe how topography(LS), land use (C), soil type (K) and precipitation (R) effect the erosion.All of them have been modified to a greater or lesser extent.

Kylmaskinerna på Saab ABs fastighet i Järfälla står för en stor del av den totala användningen av elektricitet i fastigheten. Därför är det viktigt att undersöka och analysera hur dessa kylmaskiner presterar i dagsläget och vilka åtgärder som kan vidtas för att förbättra prestandan.Detta examensarbete har fokuserat på hur kylmaskinerna i D-huset på Saab i Järfälla presterar. Därför har flera tester på dessa kylmaskiner utförts. Mätvärdena har huvudsakligen registrerats med ClimaCheck utrustning och uppmätt data har analyserats med datorprogrammen Refprop, Energy Equation Solver och Excel.  Undersökningar av kylmaskinerna i D-huset har visat på flera upptäckter. En upptäckt är att köldmedierna inte har rätt sammanställning.

Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.

Syfte: Syftet med denna studie är att utreda månadsavgiftens inverkan på bostadsrätters försäljningspris och få en indikation på hur rationellt den studerade marknaden fungerar. Den formella hypotesen är: Leder låg månadsavgift till högt försäljningspris och vice versa? Dessutom undersöks hur månadsavgiften kapitaliseras in i bostadsrätters försäljningspris.Metod: Denna studie baseras på information om bostadsrättsförsäljningar i Gävle under år 2008. En omfattande manuell databehandling har utförts för att kunna genomföra studien. De prispåverkande faktorerna har klassificerats utifrån deras förmodande inverkan på priset.

Till följd av den globala finanskrisen som startade under 2008 implementerade Riksbanken flertalet extraordinära åtgärder med syfte att dämpa konjunkturnedgången och säkra ett väl fungerande betalningssystem. Dylika åtgärder kan ge allvarliga följder och problem i ekonomin såsom exempelvis förtroendeproblem för de finansiella och penningpolitiska myndigheterna, hyperinflation mm. Det är därför av intresse att undersöka huruvida de genomförda åtgärder lett till måluppfyllelse eller ej, givet den problematik som präglar ekonomin under anormala tidsperioder.Genom uppsatsen har författarna använt sig av The 3-equation New Keynesian Model, även kallad IS-PC-MR modellen med Taylorregeln som ränteregel samt IS-LM modellen för beskrivande av likviditetsfällan. Empirin baseras på data från Riksbanken, Konjunkturinstitutet, SCB m.fl. Även en del intervjuer har genomförts via mail med anställda på Riksbanken för att på så sätt fördjupa insynen i problematiken.

An interview study of horsemanship has been conducted in the community of Ängelholm. The study is part of a larger project, where a further four students who are writing their thesis? have conducted interviews in Lerum, Hässleholm, Nyköping and Enköping, a total of 52 horse holders in 5 different communities. The collective results are summarised in "Hur hålls hästarna i Sverige och vilka är motiven" by Catharina Svala. The purpose of this larger report has been to examine why Swedish horsemanship is the way it is today through communication with the various horse holders.

The last decades have shown increased nitrogen leeching from soil to water recipients. This is inSweden mainly due to over-manuring of agriculture land, effectivization of drainage systems and thedeclining extent of wetlands. The accumulated amount of nitrogen in water doesn?t only make itunsuitable for use by humans and cattle, but also decreases the biological diversity as well as negativelyaffect tourism and fish industry. In the most severe cases shallow maritime grounds can be completelydepleted of oxygen due to decomposition of the increased amount algae and plankton growth.This study have the aim to describe and quantify the nitrogen leeching from the Genevad drainagebasin, located in southern Halland, Sweden.

The aim of this Master?s thesis was to find out more about the delimiting quality- and shelf-life parameters over time for liquid oat-based products. According to that, to present applicable subjective and objective shelf-life test approaches at accelerated conditions. The study aimed to gain a deeper knowledge concerning the general and accepted way of performing accelerated storage tests. This study focused especially on products, which suffer from quality failure caused by oxidation, such as liquid oat-based products.

This report was written as a final thesis within the Department of forest economics at the Swedish University of Agricultural Sciences as a completion of the M.SC Forestry programme. The aim of this study was to create a model that, with respect to given stock levels, temperature, fuel usage and fuel price, would identify the optimal levels for purchase of bio fuels, optimal levels of incineration of bio fuels and the sum of the present values of all costs. The model would be applicable for a larger district heating plant. Data regarding temperature were received from SMHI. Information considering fuel prices was taken from the Swedish Forest Agency and the facts about fuel usage were collected from a large district heating plant, located in the southwest of Sweden. For the temperature, a sinus curve was adapted to describe the temperature over a year.
