Detta har gjorts genom intervjuer med berörda, och statistik samling i existerande dokument. Materialet har översatts i en modell vilken har simulerats i programvaran AutoMod och analyserats i programtillägget AutoStatTM.1 System 2000 monterar man höj och sänkbara badkar för rörelsehindrade personer.

The purpose of this study is to create a method that can be used to produce decisionsupport data for the climate goals of a municipality. The method should be able to demonstrate the potential for reducing energy use and greenhouse gas emissions for measures aimed at the stationary energy system in the municipality. It will be used to make longterm projections of energy use and greenhouse gas emissions in order to be able to demonstrate the ability to reach climate goals. The aim was also to test the method's applicability by using the municipality of Uppsala and the Uppsala climate protocol project in a case study. Uppsala climate protocol is a project consisting of participants from business, government and organizations that voluntarily want to commit to reducing their carbon footprint by reducing their energy use and thus work to achieve the municipality's overall climate goal. Public reporting of energy use and climate impact has been studied in order to examine the nature of indicators and accounting figures that are commonly used in the field and how long-term forecasts are formulated. In connection to this, the type and sources for the kind of data needed was also examined.

Wastewater treatment is increasingly controlled by the Swedish environmental quality objectives, adopted by the Swedish parliament. There is a need for a sewage system that can fulfill stringent requirements concerning the environment, recycling and resource use and hygiene. Additional environmental aspects in recent years are the impact of climate change, new knowledge about the effects of pharmaceuticals in water, the need for improved wastewater treatment and increased recycling of nutrients to agriculture. This report has, from a future scenario of the year 2050, analyzed seven different systems for wastewater treatment and treatment of compostable biowaste from households in Eskilstuna. A future scenario was chosen based on that within a forty year period new challenges may arise which can result in higher demands on sewage treatment than those we see today. Another reason why the future scenario was established is that changes in wastewater treatment systems are slow to establish. The analysis is mainly focused on the economical aspects but environmental aspects such as emissions to receiving waters and potential recycling of plant nutrients has also been evaluated briefly.

Syftet med den här studien var att undersöka om det finns någon skillnad i prestation beroende på om rekryteringstestet har en koppling mellan test och arbetsuppgifter och när denna koppling saknas. Ytterligare ett syfte var att undersöka om det finns något samband mellan en persons prestation och dennes uppfattning om testet. För att undersöka detta gjordes en enkätstudie. En enkät konstruerades som bestod av tre delar; den första delen beskrev ett rekryteringsscenario som deltagaren ombads sätta sig in i, den andra delen bestod av ett kognitivt test och den avslutande delen bestod av frågor angående hur rättvist deltagaren uppfattade testet. Resultatet visade att det inte fanns någon skillnad i prestation beroende på vilket scenario man tilldelats.

At nuclear power plants, electrical valve actuators are important for ensuring that the reactor core is water covered and the pressure in the reactor tank and containment is limited. The electrical actuators are provided with overload protection in case of drawing higher current then the motors are rated for. When safety manoeuvres are needed, the overload protection must not trig and cause the valve to stop before completing the manoeuvre. Analyses have showed that the current settings of the overload protection may cause an illegitimate trig at the worst theoretically possible accident. A new method has been developed with conservative assumptions and applies overload protections for all electrical valve actuators at the three reactors in Forsmark..

This essay describes how Örebro läns landsting operate concerning the delegation of work environment tasks in their organization. In the essay we review present law, with the focus on the delegation of work environment tasks. The purpose is to see if Örebro läns landsting are following the law in a correct way.Through interviews with people responsible for the work environment, and representatives for the workers in these questions, we could see how Örebro läns landsting were fulfilling there obligations in the role of employer. The result described how they were motivated and how they systematically worked with work environment issues. However, we could also see that the structure of the division of work environment tasks were inadequate.

The EU has had a special agreement with their former colonies in Africa, the Caribbean and the Pacific Islands, the ACP-countries, for almost 30 years. This has granted the ACPs with preferences on the Europen market, which have been excluded from other countries. The agreement is now beeing re-negotiated to make it more in terms with the rule of the WTO?s most favoured nation-principle. The new agreement will differ from the present one as it will be a mutual free trade agreement where the ACP countries will open their markets to the EU as much as the EU opens up it?s market to them.

I Sverige har debatten om brand i hallbyggnad pågått under en längre tid. Grundkravet enligt EKS 8 för hallbyggnader som innehåller samlingslokal är R30, men konstruktionsdelar som vid kollaps inte leder till fortskridande ras eller ger för stort skadeområde kan förbli oskyddade. Framförallt handlar debatten om möjligheter till oskyddade takbalkar av stål samt vilka verifieringsmetoder som ska vara tillämpningsbara.I denna studie har FDS-simuleringar utförts med olika scenarier där parametrar som bland annat bränsletyp, takhöjd och öppningsstorlekar har varierats. Dessa scenarier har jämförts och parametrarnas betydelse har analyserats. Fokus i denna studie har varit analys av temperaturerna i takbalkarna, men även utrymningssimuleringar har utförts i programmet Evac.

The purpose of the essay Multi criteria analysis of potential conflicts concerning land use planning - natural stone mining in Lysekil municipal is to study possibilities and limitations in GIS based multi criteria analysis as a tool for land use planning. How GIS based multi criteria analysis can be implemented to localize potential conflict areas between natural stone mining and other land use activities and what advantages and disadvantages the method holds are the main issues of this study. The essay studies these questions through a case study, concerning the geographical area of Lysekil municipal in western Sweden and problematizes the interest of natural stone mining in relation to other land use interests. A literature study was carried through, concerning multi criteria analysis and planning. After collecting and processing of data the multi criteria analysis could be implemented in the ArcGIS tool Weighted Sum.

The Aquatic Ape theory was first formulated by Alister Hardy in year 1960. All from the beginning the theory has been criticized, ridiculed, ignored and a source to strong feelings in the anthropological community. The purpose of this essay is to investigate why the Aquatic Ape theory is so controversial and why it is understood so differently by scientists. After interviews with Swedish scientists and the general community, and after reading of anthropological books, I have tried to show that the aquatic ape-coldness depends on it challenging nature against the anthropological paradigm, which describes human beings as strong, hunting creatures who can live in any environment. The Aquatic Ape theory - on the other hand - picks out one of all these environments and says: "here has our evolution occurred: we have been aquatic apes".

The starting point of this study is theories of European integration, which are used to formulate different scenarios about the future of the European Union. This is made in regards to the eurocrisis which has intensified the discussion about how to change the construction of the euro to overcome the economic difficulties that has arisen. In this study, four different scenarios are presented: "An updated Europe", "A new Europe", "The death of the euro" and "Goodbye Greece". The first two scenarios takes its starting point in the neofunctionalist theory of European integration and describes how the EU might increase its level of integration in different ways. We can either see a development where the EU tries to improve the implementation of the rules that are meant to coordinate the member states? economic policy, or we might encounter a more advanced integration where fiscal policy competences are transferred to the EU-level.The latter scenarios, however, takes another theory in to account, liberal intergovernmentalism, and describes how the eurozone might be fragmented in different ways due to conflicts of interest between lenders and countries that has to receive loan-packages.

The swedish healthcare is in many situations one of the best in the world. But still, the healthcare system includes elemnts that reduce the efficiency. Partly becouse the swedish healthcare is largely monopolized, the servicecs are not properly prized and the economic responsibility and the liability legislation is limited. The main problem this study evolves around, is how a different liability rule would change the shape of the healthcare organisation. Abouve all, how would the approach to riskmanagement and preventive and riskreducing performance change with a diffrent liability rule.

Detta examensarbete har utförts på Saab Support and Services i Arboga. Syftet med examensarbetet har varit att ta fram en modell i Matlab som skall beräkna antal motorbyten, och hur många stora motortillsyner (Check 3) det kommer att bli. Detta skall utföras för att få en så kostnadseffektiv drift som möjligt fram till valt slutscenario, med 40 SK60 det vill säga 80 stycken RM15 motorer i drift. De scenarion som har påverkat projektet har varit 2014 VT, 2017 VT samt 2020 VT. Projektet har delats upp i två moment, där det ena har varit att skapa en databas i Excel för alla motorer och det andra är ett program i Matlab som skall bearbeta all data från Excel, för att på så sätt kunna få ut det mest optimala tillvägagångssättet.Det som vi har kommit fram till är att scenario 2014 VT kommer att uppnås med de aktuella motorer som finns tillgängliga idag utan att någon motor skickas iväg på Check 3.
