The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.

Inledning och problemdiskussion: Den senaste tiden har svenska bolaget Eniro varit inblandad i en redovisningsskandal där den tidigare vd:n Johan Lindberg polisanmälts för att ha manipulerat bolagets intäkter. Eniro står nu inför en svår period där långivarna överväger att sätta bolaget i konkurs och möjlighet till nyemission verkar inte trolig.För ett gynnsamt näringsliv är det viktigt att intressenter känner förtroende för noterade bolag på aktiemarknaden. Att bolagen redovisar korrekt information är avgörande för att investerare ska känna förtroende för bolaget, vilket ifrågasätts vid redovisningsskandaler likt den Eniro nu står med.Syfte: Att analysera Eniros finansiella ställning och dess utveckling år 2007 till 2014, för att se på samband mellan förändringar i finansiella ställningen och bolagets börsvärde.Avgränsningar: Studien kommer att baseras på årsredovisningar från år 2007 till 2013 samt tredje kvartalsrapporten år 2014. Denna period är vald då den ger en bild av bolaget innan och under finanskrisen, samt de år som den felaktiga redovisningen skedde och efter att den upptäckts.Metod: Uppsatsen är en fallstudie av Eniro och består av både sekundär kvalitativ och kvantitativ data. Kvalitativa data är nyhetsartiklar om bolaget och verksamhetsberättelser som finns i Eniros årsredovisningar.

Today green tree retention, together with leaving dead wood, is a common practice with the aim to reduce negative impacts on biodiversity and environment due to clear-felling. To better understand whether this conservation practice also makes a long-term difference, it is important to know what happens to these trees after harvest. Few studies have made an assessment of what happens to retention trees over a longer time period. In this study I inventoried retention trees that were left at clear-cuts six, twelve and eighteen years ago. I carried out a re-inventory of 57 retention patches (divided into free-standing tree groups, small swamp forests and edge zones) and free standing dead trees, spread over 25 previous clear-cuts in central Sweden.

The numbers of mergers and acquisitions have increased significantly in the last period of time. Although this popularity for mergers and acquisitions, most of the mergers and acquisitions fail to create value. One explanation to this failure of value creation is, according to several studies, how companies treat integration of information systems in the pre-merger evaluation. The research within the field argues that information system integration should have a proactive role in mergers and acquisitions, meaning that information system integration should support the organizational change and normally be considered in the premerger evaluation. The aim of this thesis is to study issues that affect whether companies choose to consider information system integration proactively, when involved in mergers and acquisitions.

I detta arbete testar jag för ett långsiktigt penningefterfrågesamband samt för transmissionsmekanismen i Sverige under perioden 1973-2003. Jag antar att det finns en fungerande räntekanal och testar för (i) långsiktig prishomogenitet, (ii) en gemensam stokastisk trend hos inflationen, den kortsiktiga räntan och den långsiktiga räntan samt (iii) att den aggreregerade inkomsten anpassar sig till ett långsiktigt IS-samband eller en kortsiktig Phillipskurva. De sista två antagandena förkastas och transmissionsmekanismen har därför under denna period inte fungerat enligt underliggande ekonomisk teori. Jag finner också ett långsiktigt penningefterfrågesamband men den reella penningmängden och den långsiktiga räntan är svagt exogena, vilket talar för behovet av internationella räntesatser i alternativkostnaden..

This paper is about how the teaching profession have got a changed status from the perspective of the teachers. The papers cause is to find out how the teachers think that their status have changed in a period of 30 years. Interviews have been done with eight middle school teachers from two schools in the municipality of Södertälje. The answers from the interviews have been put in relation to theories in research of professions. Three hypotheses have been put up to apply the theories on the answers.

During the 1994 Italian elections many things were new for the voters. A new election system, new parties emerging where old traditional ones were dying out because of long ongoing corruption scandals that were coming up to the surface. In all this one man, Silvio Berlusconi, a famous Italian businessman, stepped in and with his two allied parties Lega Nord and Alleanza Nazionale he swept away the nation in a never before seen election campaign. Many things have been said about the motifs and the way he prosecuted the election campaign for the Forza Italia. But what I try to see for this thesis is the awereness in the Italian print media from this particular period - how and if the debate about an in just electoral campaign existed in the country from the date Silvio Berlusconi entered ?the playing field? as he called it and up to the days of election..

Today we have more game species than ever before in our landscape, both regarding number of species and number of individuals. The increasing number of wild species is an increase in game recourse for the countryside. The increase of game species, however, has negative effects on forests and agriculture land. The negative effects for forestry are damages on economic important trees, due to losses in production and quality. However there are ways to decrease the damage on valuable and important trees.

According to the current regulations described in IAS 27 - Consolidated and Separate Financial Statements, an investment company is required to consolidate all entities that it controls. However, this thesis outlines the creation of a new system, where those entities are instead measured at fair value, taking changes in fair value into account in the income statement. By recalculating the consolidated accounts for five major investment companies in accordance with the new system, this investigation concludes that the new system would provide investors with more relevant but less reliable accounting information. In addition, the historical financial performance of Investor, Industrivärden, Ratos, Kinnevik, and Lundbergföretagen, is evaluated using their recalculated consolidated financial statements. The evaluation indicates that the overall volatility in the companies' consolidated financial statements would have been higher during the time period 2005-2009, in comparison to official reports..

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

This is a study of why Japanese comics, so-called manga, in such a high degree make Swedish readers eager to write and draw comics themselves, and what didactic implications this might have for teachers working in Sweden. To answer this, the author has put together a focus group of Swedish artists influenced by manga, and also used a questionnaire at two Swedish art schools, where young artists are taught how to draw in a manga style. The results show that it is the compelling storytelling and the focus on the characters that enthral readers about Japanese comics, but that it is the seemingly simple style that makes the readers think they themselves can master it. The fact that the interest in both reading and creating manga, almost completely overlap with the so-called period of oppression (between the ages of 11 and 14) when most students lose interest in creating art, is something that could and should be used in the Swedish educational system..

The purpose of this study was to gain understanding of orthodox Christianity in Swedish educational material. The aim was to compare the presentation of orthodox Christianity towards pupils before the new curriculum and after. With the help of an analytical approach by Bergström and Boreu ?s and the interpretation strategy by Quentin Skinner, I have studied material used in school for the subject religion. I have limited my educational material in one way.
