A Biogas plant in SLU?s (Swedish University of Agricultural Sciences) management sustains to behave in con-nection with the new animal stables at Lövsta. There will primarily manure from stables that rot to biogas. The biogas plant will also have the capacity that rot others substrates that can arise in the farm operation. The aim with the biogas plant is to produce non fossil electrical and gas heat for own customs, to reduce smell impact from stables and to make possible different types of research investments within the area.This study has implemented multiple cases study of different investment scenarios.

Denna rapport är ett resultat av det examensarbete som är den avslutande delen på utbildningen industriell design vid Luleå tekniska universitet. Examensarbetet har omfattat 2x20 poäng och har genomförts åt Liko AB i Alvik, Luleå, våren 2006. Liko är en av de ledande tillverkarna av personlyftar och lyftselar i världen. Syftet med projektet var att se över och förbättra en redan befintlig produkt, en lyftväst, som Liko tillverkar och säljer. Lyftvästen har inneburit nya möjligheter för rehabilitering av vuxna och habilitering av barn.

Sverige och EU har man som mål att halvera energianvändningen fram till 2050 och det arbetet måste starta nu. Det är 15 miljoner kvm byggyta som måste halvera sin energianvändning varje år och i 40 år framåt. Redan idag är 70 % av alla hus till 2050 byggda, vilket innebär att även om vi skulle bygga passivhus fram tills dess skulle det inte räcka för att nå målet. Det är alltså en stor utmaning att halvera energianvändningen till 2050. En jämförelsestudie har genomförts mellan två värmeåtervinningssystem.

Bakgrund: Delaktighet är förutsättning för god vård, och en rättighet för patienten. Delaktighet bygger på god kommunikation mellan vården och patienten. Personer med afasi efter stroke kan ha nedsatt förmåga att förstå information, och uttrycka behov och önskemål. För att de ska kunna delta i beslut om vård och behandling har de behov av extra stöd från omgivningen. Arbetsterapeuter som ofta möter patienter med afasi som följd av stroke kan ha nytta av att veta hur omgivningen kan anpassas för att stödja dessa patienter.Syfte: Belysa omgivningsfaktorer som kan inverka på delaktighet i vården för patienter med afasi, och hur dessa kan skapa förutsättningar för delaktighet.Metod: Litteraturöversikt. Resultat: Omgivningsfaktorer som inverkar på delaktighet för patienter med afasi är fysisk och social omgivning, och vårdens system.

This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.

This report is of technical character and treats how to plan a small building in Borlänge, Sweden.The technical components that have been treated in the report are the construction, foundation,installations and thermic abilities of the house. In addition to planning this house the report alsocontains a part that deepens in net zero energy buildings. The purpose of the report is toinvestigate if the house in Borlänge can be constructed to meet net zero energy buildingdemands.Energy efficient houses such as passive- and net zero energy houses are showing more frequenton the market in Sweden. Ongoing climate changes and growing consciousness about theenvironment in society have contributed to that the environment is a well discussed topic. Toconsume small amounts of energy and at the same time produce local energy is thereforesomething that lies in the future and future houses.

Bakgrunden till föreliggande studie är att stroke är en av Sveriges stora folksjukdomar och afasi kan uppkomma som komplikation. Detta kan medföra problem vid kommunikationen och vårdrelationen kan bli lidande. Syftet med denna litteraturstudie var att belysa vårdrelationen med strokedrabbad patient med afasi ur ett vårdarperspektiv. Studien grundade sig på sex vetenskapliga artiklar som granskades genom innehållsanalys inspirerad av Burnards (1991) analysmetod. Analysen resulterade i tre huvudgrupper med undergrupper vilka belyser olika aspekter för att skapa en god vårdrelation.

Abstract   This degree project comprises 30 credits, i.e. 20 weeks of work. The work mainly deals with the energy balance for a multi-family house in Västerås and the requirements for energy conservation in the Swedish building code, BBR. Calculations of the energy balance are supplemented by a number of interviews. Energy conservation in general has become more important in recent years and the subject is in line with increased public awareness. This importance and attention is explained by environmental problems in general and global warming in particular, but also by rising energy prices.

Syftet med detta examensarbete har varit att genomföra en nulägesanalys av Hall 7 på Sapa Heat Transfer AB i Finspång. Utifrån nulägesanalysen togs åtgärdsförslag fram som kan generera en effektivare uppvärmning, mindre yttre utsläpp och behagligare arbetsklimat. Problemet i Hall 7 är att processventilationen för varmvalsverk 2051 är ålderstigen och underdimensionerad, den saknar även värmeåtervinning och rening av processfrånluften. Detta leder till oplanerade driftstopp, höga underhållskostnader samt hög energianvändning.För att finna åtgärdsförslag för dessa problem genomfördes en nulägesanalys av Hall 7 genom att mäta luftflöden och temperaturer, analysera utsläppsmätningar och energianvändning samt intervjua personal.Utifrån dessa mätningar har fyra olika åtgärdsförslag tagits fram. De fyra åtgärdsförslagen är benämns: YIT, YIT (Enklare), Homehall och Ökad tilluft.Det åtgärdsförslag som anses vara bäst lämpat för att generera en effektivare uppvärmning, ge mindre yttre utsläpp samt ett behagligare arbetsklimat i Hall 7 är åtgärdsförslag Homehall.

The purpose of the house which is the basis of this report is to be able present itself on the market as a relatively cheap and at the same time a climate friendly choice. The house is supposed to be able to be built anywhere in Sweden and the rest of Scandinavia in a short period of time. This puts demand on what kind of heating system the house can have, since not all places have the geographic advantage of being able to use geothermal or district heating. Therefore the heating system choices will only include those that are not limited by their geographic location. The house will be built in modules which only require the groundwork to be done before the house can be erected. In this report "System solutions for plus or passive-housing" a comprehensive literature search has been conducted as well as a number of calculations.

Abstract Background: In 1997 the Kyoto Protocol was signed, it?s an international agreement which is aimed to reduce greenhouse gas emissions. Sweden's goal is to reduce energy using in buildings with 20 percent by 2020 and 50 percent by 2050. This is a comparison with levels from 1995 (Glad, 2006). For Sweden to be able to reach its goals, they need to construct more low-energy buildings (Åhman, Wahlström & Lundblad, 2010).

Each year, the coffee machines at Ericsson in Kista produce around 100 tons of ground coffee waste.The companies Coor Service Management, Löfbergs Lila and Selecta are all responsible for differentstages in the logistical chain in delivering coffee and, together with Ericsson, they want to increasetheir environmental benefit. The plan is to produce biogas through anaerobic digestion instead ofincinerating the coffee waste in a heating plant. The results are to be presented as different businesscases in which different biogas plants are compared with the reference case (heating plant),comparing costs and environmental impacts.There are two major environmental benefits from producing biogas; reduced carbon dioxideemissions from when fossile fule is replaced by carbon neutral biogas, and reduced emissions fromreturning digestate from the bio reactor to farmland instead of using industrial fertelizer.In order to determine the biogas potential in coffee waste, a couple of properties had to bedetermined in a laboratory. Properties such as the dry substance content, heating value, moisturecontent and ash content. The results show that 100 tons coffee waste could produce around 16 500Nm3 biogas which would contain 163 MWh.The biogas reactor and upgrade plant both need energy gas to function and uses around 14 MWh ofthe produced gas.

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.

During the past 30 years the fuels for energy production in heating and power plants have changed. Fossil fuels have decreased in usage whereas bio fuels in Sweden have increased with 60% since the 1970's. Different fuels affects combustion and the release of various substances and particles into the flue gas. This is caused by the diverse components and chemical structures of fossil fuels and bio fuels. When the flue gas leave the combustion chamber and enters the path to the chimney particles in the gas are being transported out of the combustion chamber.
