Kvarteret Kajutan - Från lågenergi till plusenergi

Energy and environmental demands regarding buildings have become an increasinglydiscussed topic, both in Sweden and in Europe as a whole. The general trend indicatesthat greater efforts are being put into the energy efficiency of the built environment.There are already numerous examples of houses with a low energy demand, and thenumber of low energy buildings is constantly growing.At the time being, the maximum level for energy demands for housing in Stockholm is110 kWh/m2year, but as soon as next year the limit will be changed to 90. The Swedishagency Energimyndigheten is currently conducting a project to interpret the EU Directiveon the so-called Nearly zero energy buildings, and the preliminary results indicate thatthe level of requirements for purchased energy will end up with about 55 kWh / m2year,which is in line withtoday?s recommendationsfound in FEBY's Kravspecifikation förPassivhus.Starting with a low-energy house in Henriksdalshamnen in Stockholm, we have analyzedvarious energy-efficiency measures and their influence on power and energy needs. Thefinancial aspects associated with the measures have been studied using a model of lifecycle costs.The measures were initially studied individually to give an idea of how much impact theyeach had.

Gröna upplevelser för alla : en trädgård för habilitering och återhämtning

Jällaskolans upper secondary School is situated on a big farm just outside Uppsala. The School is focused on agriculture, forestry, gardening, animal care and science. Jällaskolans staff has whished for a school garden for educational purpose where students can practice their gardening skills and learn more about plants. But most important, a specially adapted outside environment such as a garden, would be a great advantage for the students with special needs. This garden could even be an asset for other visiting school classes in the region.

Termomekanisk utmattning av Sanicro 25 : Materialmodellering med finita elementmetoden

The report aims to describe the austenitic stainless steel Sanicro 25 from a thermomechanical point of view. The thermal and mechanical properties of the material make it suitable for use in coal ? and thermal power plants. By the use of Sanicro 25 it would be possible to bring the efficiency of these plants up while bringing the carbon emissions down.A material model is created from material testing and validated through simulation in the finite element software Abaqus. The model that has been derived describes the material behavior during loading and stress relaxation for the first cycle in a thermomechanical fatigue test well.

Dopning vid hästbesiktning

The aim of the project was to investigate if Swedish rodents, brown rat (Rattus norvegicus), house mouse (Mus musculus), wood mouse (Apodemus spp) and water vole (Arvicola terrestris) captured in pig herds and in urban areas, constitute a reservoir for pathogenic Leptospira spp. Under Swedish conditions leptospirosis gives rise to reproductive disorders in pigs and symptoms of flu in humans. It has long been established that rodents are chronic carriers of pathogenic leptospires in their kidneys, and can spread the bacteria with urine. The old nomenclature of serovoars is still in use, but a new system of genetic classification has developed and today the genus Leptospira contains 17 species. There are several diagnostic test developed for leptospirosis.

Elevers tankar om klimatförändringar

This work examines the students´ thoughts on climate change with a focus on carbondioxid through photosynthesis and the carbon emissions from cars. The study is based on two subject areas, one with a focus on enhanced greenhouse effect, and the other focusing on photosythesis. The survey was conducted by means of qualitative interviews with students in grades four and six. The results describe that student´s understanding for photosynthesis and the carbondioxids function for photosynthesis doesn´t change significantly from grade four to grade six. I have divided the students inte three levels based on their understandingof the various fields, and their use of adequate concepts.

En hållbar framtid med Gröna Byggnader.

På Sveriges fastighetsmarknad har man de senaste åren kunnat urskilja ett allt högre fokus påmiljön från dess aktörer. Miljödebatten i Sverige har snabbt fått fäste och allt fler företag förstårvärdet av att fokusera på sådana frågor.Att utvecklingen fortsätter att gå framåt är viktigt då fastigheter och dess tillhörande byggnaderstår för nästan en tredjedel av världens utsläpp av växthusgaser och bara byggandet och driftenstår för cirka fyrtio procent av den globala förbrukningen av råvaror och energi. Prioritering avmiljöfrågor blir således viktiga vid fastighetsförvaltande och nyproduktion.Tidigare forskning visar att det finns en mängd incitament för att bygga och förvalta grönt. Ävenhyresgästerna har incitament för att hyra gröna lokaler. Vidare visar internationella studier att detinte alltid krävs stora åtgärder för att uppnå bra resultat vad gäller fastigheters energiförbrukningoch hållbarhet över tid.

En pilotstudie av unghästars användning av ligghall i grupphållningssystem

Today, individual indoor stalls and individual outdoor paddocks are the most common way to house horses in Sweden. The way that we manage, house and feed the horses are not optimal for the species natural basic behavioural needs. However, the awareness of this grows in the context of research and the emergence of alternative housing systems. One of the alternatives to the traditional format in individual boxes is called group housing. Group housing systems allow horses to live in herds and they can choose how they want to distribute the hours of the day between movement, resting and foraging. The purpose of this study is to examine how frequently the young horses in a group housing system use the indoor lying area.

Ökad användning av biodrivmedel i vägtransportsektorn : en styrmedelsanalys

The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010. More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.

Är gnagare reservoar för patogena leptospiraarter i Sverige?

The aim of the project was to investigate if Swedish rodents, brown rat (Rattus norvegicus), house mouse (Mus musculus), wood mouse (Apodemus spp) and water vole (Arvicola terrestris) captured in pig herds and in urban areas, constitute a reservoir for pathogenic Leptospira spp. Under Swedish conditions leptospirosis gives rise to reproductive disorders in pigs and symptoms of flu in humans.

Mean value modelling of a poppet valve EGR-system

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

Biodiversitet av evertebrater på vegetativa tak

In a city sometimes conflicts arise between either to save the species-rich vacant lots where many species thrive, or to build new buildings. Green roofs can then serve as a refuge for plants and animals that have had their natural habitat destroyed or diminished. Today we know too little about green roofs contribution to the biodiversity in the cities. We also know very little about how various types of vegetation on roof can increase biodiversity and its ability to attract different species.The aim with this study was to examine how different types of vegetation on the roofs affect the biodiversity of the invertebrate and how species-composition and number of individuals differ between the roof- and groundlevel.This study has been carried out on Augustenborg Botanical Roof Gardens in Malmo, and in an area about 1.5 kilometers away from Augustenborg. Three different types of vegetation on the roof and ground floor were selected: sedum- ruderal and grass.

En studie om de svenska riksdagspartiernas ställningstagande i EMU-frågan inför folkomröstningen år 2003

Based on widespread public debate prior to Swedish EMU-referendum 2003, the main purpose of this thesis is to examine and analyze the standpoint of the Swedish parliamentary parties in the EMU-issue, from perspektive of the following questions;1) What is the official standpoint of the parliamentary parties in the EMU-issue?2) What claimed effects of a Swedish EMU-membership or non-membership have the parties presented?3) What rifts can be found within the parties, in relation to their official standpoint in the EMU-issue?The Sweidish parliamentary parties´ standpoint in the EMU-issue will be analyze from the point of view of a number of current theories. These theories are basically democrazy theories that all have transnationalization and Europeanization as a common ground.The conclusions are, among others, that the parliamentary parties` standpoints in the EMU-issue are based on ideological values about whether or not a Swedish EMU-membership is good for Sweden. The Liberal Party, the Christian Democrats, the Moderate Party and the Social Party have a positive view on EMU and a deeper European integration, and basically value the economic efficency of the EMU higher than democratic decision making and a national currency and monetary policy. As for the EMU-critical parties such as the Centre Party, the Green Party and the Left Party, their view in the EMU-issue can be regarded as more nationalistic, since they say no to an exapanded financial cooperation.
