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.
Materialvagnstransport
A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Strömkontroll till aktiva magnetlager med noggrann och störningsreducerad strömmätning
There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).
Kostförändring och/eller fysisk aktivitet vid fetmabehandling
The aim of this study was to investigate whether a dietary change, physical activity or a combination of both gave the best result when treating obesity, concerning weight loss and BMI. Excessive weight and obesity are today a big health-issue and it is estimated that 10 % of the men and 12 % of the women in Sweden have a BMI over 30, i.e. are suffering from obesity. The corresponding number for children is 3 %. No one can say for sure what causes obesity but there are many theories.
First green kit : ett inredningsprojekt för det offentliga uterummet
Projektet omfattas av ett parkprojekt med analyser och gestaltning av grönstrukturer i Nynäshamns stad. Inriktningen är utformning av allmänna utrymmen i det offentliga uterummet med fokus att öka tillgängligheten och tillgången av grönytor och parker.Projektet syftar i att skapa värdefulla platser för ökad trygghet och trivsel. Målsättningen är också att visualisera en vision om rum för upplevelser och aktiviteter. Rum i vilka allmänheten frivilligt vistas om den fysiska miljön är god. Stadsrummet utgör en stor del av stadens identitet.
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.
Das Experiment : -ett försök att skapa den passiva studentbostaden
Byggandet av passivhus har ökat kraftigt under 2000-talet i Sverige. Dock har det inteutformats och byggts några studentbostäder i passivhus form ännu. Denna studie går ut påatt försöka utforma studentbostäder som uppfyller de svenska kraven för passivhus. Genomatt välja ut lämpligt material och komponenter, t ex. väggtyper, platta på mark ochfönstertyper redovisas olika beräkningar för energiförbrukning.I metoden till beräkningarna som genomfördes, där resultaten hamnar i jämförelse medvarandra, användes VIP-energy samt PHPP.

Matematiska utmaningar i grundskolans tidigare år : En studie om hur elever med särskilda matematiska förmågor identifieras och utmanas i grundskolans tidigare år
I denna rapport undersöktes S&P 500 Energy Index genom multipel regressionsanalys. Modellerframställdes genom regression och baserades på data hämtad från börsen. Modellerna angavs iprocentuell ändring respektive absolut ändring. Validitet för varje enskild kovariat testades och en risknivå avgjorde om en kovariat skulle inkluderas i modellen eller inte. Detta ledde till två modeller med bättre kurvanpassning till den givna mängd data över det valda energiindex.
Varumärkets utveckling till strategisk resurs : varumärkesarbete i svenska statliga bolag
Today, Sweden has about forty companies owned by the government. These are active on markets with variable competition. Some have been given special areas of responsibility that in a practical notion make them monopolists. The period when most public companies where formed (and with that the following subjection to competition) during the nineties and early 2000's, forced the formerly protected businesses to act on the terms of the open market. Parallel to this development the brand has for the last twenty years evolved into something great strategic importance for the business, including the business-to-businesses (B2B).
Värdet av demand response på den svenska elmarknaden
Intelligent IT-based solutions, often called Smart Grids, are considered to be the future balancers of renewable energy sources. One area within the Smart Grid concept is called demand response, which is focused on making customers more consumption flexible by making them more active in their consumption. In this thesis the aim is to analyze a business model by investigating the income potential for a demand response solution as well as its market potential. This has been done through literature studies, interviews and development of a computational model.The use of 5000 households with flexible consumption can provide a cost reduction of 17.2% or 2.4 million SEK for a balance responsible party during an average year. If the solution is used to make strategic bids on the regulation markets the study indicates that the largest potential for revenues lies within this strategy.
Biogaspotential hos våtmarksgräs
BIOGAS POTENTIAL IN GRASSES FROM WETLANDSMarvin MartinsThe purpose of this study has been to survey wetlands that are suitable for mowing and to analyze the biogas potential in the harvested grasses. A preformed investigation showed that there are suitable wetlands, which can be harvestable, namely those mowed formerly in traditional haymaking. The practice of traditional haymaking is dying out in Sweden today but there are several good reasons why it should to be reconsidered. Nature- and cultural values are obvious, also the unutilized energy in the grass.The suitable types of wetland that were specifically studied were the productive wetlands; meadow marshes and wet meadows. These wetlands are represented in the Swedish meadow- and pasture inventory database; (TUVA) and the Swedish national wetland inventory (VMI).
