Modellerade och uppmätta kväveflöden i energiskog som bevattnas med avloppsvatten

The aim of this essay was to study the nitrogen flow in two willowplantations, at different locations in the south of Sweden, that wereirrigated with sewage. The study was also performed to compare thedifferences in nitrogen flows between two years, 1998 and 1999. The studywas made in three parts. First, the denitrification activity was measuredusing the acetylen inhibition method. Second the nitrogen flow, as well asthe water- and heat flows, were modeled through the SOIL-SOILN-modelThird; the nitrogen flow was calculated to compare with the results fromthe model.The results from the measurements were then compared with the resultsfrom the SOILN-simulations to detect differences in the denitrificationrate.

Juniorfinansiering i fastighetsbranschen? Fokus kring Mezzanine

Real estate financing is one of the key figures for financial success and fundamental to asuccessful business. Funding will come in several different ways, from existing cashflows andassets to new capital requirements which are aimed at different markets.These markets are constantly changing and since the recent financial crisis, there have beenadjustments and austerity measures which led to that the banks have become more restrictive intheir lending.The real estate industry is characterized by both long-term and short-term thinking that ischaracterized by a solid continuity. Our thesis discuss how the demand is in the real estatebusiness and how mature the Swedish market is for junior financingwith focus aroundmezzanine debt and where are we headed in the near future.We've reached out to the key players in the industry on both the buy and sell side of real estatefinancing but also people between lenders and borrowers that handles transaction advice. Tohave been able to implement the analysisa survey and simulation of an investment calculationwas created. This questionnaire was answered by many real estate companies with senior peoplethat had operational positionsmost associated with corporate commitments.

?Att hjälpa eller stjälpa? : Kvinnors upplevelse av missfall och vård vid missfall

Background: Miscarriage is one of the most common complications connected to pregnancy, every fourth woman undergoes a miscarriage during her lifetime. There is often no medical explanation why miscarriage happens, although the risk may increase due to certain factors in lifestyle or diseases. During incomplete miscarriages medical or surgical treatment is needed.Women are treated at surgical or gynecological departments and the period of treatment is often very brief, on some occasions not even a day. Therefore, the nurse faces a great challenge in meeting the women?s needs during the period of treatment.Aim: The aim of the study is to illuminate womens experiences of miscarriage and the treatment they experienced.Methods: A systematic literary study containing 13 articles.Results: Miscarriage is an individual experience and many women are affected emotionally and have many strong feelings afterwards.

Simulering av energieffektiviserande åtgärder för små- och flerbostadshus : Möjligheter för JM:s hustyper att uppnå passivhuskonceptet vid nybyggnation

The purpose of this project was to evaluate how energy efficiently some of JM?s residential buildings can become in standard production. What kind of measures are needed to achieve the level of energy demand that is included in BBR12 (Boverkets Byggregler)? What measures are needed for achieving a lower demand so that the buildings could be classified as passive houses? The investigation has included a single family house and two different types of apartment blocks.The simulation programs Enorm and VIP+ have been used to calculate the energy demand of the buildings. The results from the programs have been compared with the measured energy demand for the three buildings.

Meningslöshet och repetition i Cirkusdirektören och Ballerinan : En undersökning i den absurda teaterns stilistik

Futurum.kom is a collaborative marketing project with the aim of strengthening the internal organization of Länsbibliotek Sydost, Regionbibliotek Kalmar and the 25 public libraries within the southeast region. The project intends to externally build the brands of the public libraries in Blekinge, Kalmar and Kronobergs län.

What goals does the library have with the "Låna dig rik"-campaign.? What is the feedback from the staff's experience of the users in terms of needs and demands?? In which way does the library choose to implement the marketing campaign and what role do the users have in this process?? What is the internal performance of the library's marketing campaign, what was the experience of the staff of the campaign?? What is the external result of the library's marketing campaign?The method is based on a case study of a single library, with a series of interviews and document analysis of written and electronic documents.

Simulation driven design of optimized sheet metal bracket

Det ständigt ökande trycket på minskande utsläpp och effektivare energianvändning driver utvecklingen av Scanias produkter. För att varakonkurrenskraftiga på marknaden behöver man leverera lastbilar med högre kvalitet och lägre bränsleförbrukning, det vill säga sänka transportkostnaderna förkunden. Ett steg i detta är att utveckla komponenter i fordonet som är optimerade iförsta hand med avseende på hållfasthet men även mot vikt och pris. En betydande andel av lastbilens komponenter är plåtfästen som ofta underprioriteras i produktutvecklingen. Examensarbetet fokuserade därför på att utveckla metoder för konstruktion av plåtfästen.En metod för att förbättra konstruktionerna är att arbeta med simuleringsdriven konstruktion.

Risken för översvämningar vid de svenska kärnkraftverken : en statistisk och historisk extremvärdesanalys

This thesis investigates the overall risks of flooding over the Design Basis Flooding Level (DBFL) at the Swedish nuclear power plants (Oskarshamn, Ringhals and Forsmark), using statistical data and methods, but also considers historical events which might affect the overall risk of flooding at the specified sites.Considering the nuclear accident which happened in Fukushima in conjuction with the earthquake and tsunami which struck eastern Japan on 11 March 2011, operators and licensors of nuclear power plants all over the world conducted reviews and investigations on the overall risks posed to the plants from external events. One important such event is extreme water level.One part of the thesis includes an extreme value analysis (using Generalized Extreme Value distribution and Generalized Pareto distribution) of water level data from SMHI (Sweden's Meteorological and Hydrological Institute) measured at stations close to the Swedish nuclear power plants. The results of the statistical studies indicate that considering the return period used in the thesis (100 000 years), the water levels at the Swedish nuclear power plants are not expected to exceed DBFL.The other part of the thesis consists of a historical study of extreme weather-related events. The results of this study indicate that no historical events seem to have occured which would indicate a higher risk of flooding than the one suggested by the statistical study. .

Med historien som vapen ? en historiedidaktisk analys av Stefan Sundströms texter

Syftet med den här texten är att med hjälp av de historiedidaktiska begreppen historiemedvetande och historiebruk analysera hur den den svenska musikern Stefan Sundströms använder historia för att ge uttryck för ideologikritik i sina texter. Sju av hans studioalbum utgör grunden för empirin där den gemensamma kontexten är att de har givits ut under borgerliga regeringar, undantaget Fabler från Bällingebro som ges ut innan valet 2006 men som innehåller låtar som var en del i valrörelsen. Orsaken är att Sundström ser sig själv som den musikaliska delen av ett vänsterpolitiskt motståndsmaskineri. Texten diskuterar också hur historia kan användas som ett politiskt vapen. Resultaten pekar på att historiemedvetandet och den politiska musiken aktiveras i relation till en större upplevd förändring, vad Rüsen kallar ett ?borderline event?.

När en förälder dör : En studie av tre fiktiva tonåringars identitetsutveckling och coping vid förlust av en förälder

The purpose of this study is to examine how the identity of teenagers is affected by the loss of a parent as well as what coping strategies support identity development. The reactions the teenagers exhibit, in such circumstances, will also be examined. To accomplish this,  a theory package was created, comprising theories in developmental psychology, identity work, coping and theory of grief reactions of children and teenagers. This package provided a broad perspective, which facilitated the analysis. Furthermore, it made it easier to address the purpose and the issue of the analysis.

Småskalig biobränsleeldad kraftvärmeproduktion : teknik och investeringsutrymme

To achieve the requirements to decrease emissions of greenhouse gases by 20 % by 2020, Swedenneeds to increase its use of bioenergy. In doing so it seems natural that those who already haveaccess to large amounts of biofuels in the form of by-products such as straw, wood chips anddigestible materials take advantage of these assets locally. By combining production of heat withpower production at the farm it may be possible to not only reduce the direct use of fossil fuel forheating but also reduce energy costs.The purpose was to simulate different cases of using a small scale biofueled combined heat andpower plant for farm-based systems. A MatLab-model was developed and used to draw conclusionsabout the costs for production of heat and electricity with different conversion technologies.The model uses climate data to simulate the variations in heat energy demand on a day-to-day basis.The given heat demand is the base of the simulation and from this the possible electric output iscalculated. This study has focused on the impact of the following properties: electric-, heat- andtotal efficiency, fuel, fuel price and specific fuel requirements.

?Dead. He is Dead. God blesses America? : Den Amerikanska pressens gestaltning av kriget mot terrorism kring Usama bin Ladins död

Almost 10 years after the attack on World Trade Center Sept. 11 2001, Osama bin Laden was shot and killed on May 2 2011 in Pakistan. How was this event framed by the media with regards to the global war on terror? This study compares two different American newspapers ? the New York Times and the New York Daily News ? and how they framed the war on terrorism in the Middle East from May 2 to May 15 2011. By analyzing the framing in a perspective of the four functions of framing theory: define problems, diagnose causes, make moral judgments and suggest remedies, we found considerable differences in each papers frames.

Contrarian Strategier - ?En eventstudie på den svenska aktiemarknaden?

Syfte: Att undersöka om det finns belägg för att contrarian strategier genererar högre avkastning än Stockholmsbörsens marknadsindex och om detta i så fall beror på en småbolagseffekt. Metod: I vår event studie valde vi att undersöka stockholmsbörsen under åren 1993 till 2005. Under perioden skapade vi 8 portföljer med 20 aktier i varje, för dessa bolag satte vi ett gränsvärde på 150 Mkr. Vi utförde även ett liknande försök men då med en gräns på 1 miljard och satte antal aktier i portföljen till 10. Detta för att testa förekomsten av en småbolagseffekt på våra resultat.

Jesu uppståndelse: centralt tema eller detalj? En jämförelse av framställningen av Jesu uppståndelse i 12 läromedel för gymnasiet

The following study pertains to investigate the Christian belief in the resurrection of Jesus as it is portrayal in text books aimed at the course Religion 1 for Swedish upper secondary school. The study was carried out by looking at 12 selected books meant to function as teaching aids suitable for the course. The methodology covers both qualitative and quantitative aspects. The study shows that the topic of the resurrection is dealt with in a ratherneutral fashion. A survey of the evidence does not give credence to the notion that the textlength assigned to the resurrection, in any way gives greater importance to the resurrectionbeing of superior value as an Christian article of faith.The results are further discussed, and suggestions are given for how theresurrection of Jesus can function as a didactic tool for the purpose of teaching Christianityfor Swedish speaking upper secondary school pupils, in agreement and harmony with theSwedish syllabus.

Evaluation of Xilinx System Generator

This Master?s Thesis is an evaluation of the software Xilinx System Generator (XSG) and blockset for Matlab. XSG is a module to simulink developed by Xilinx in order to generate VHDL code directly from functions implemented in Matlab. The evaluation was made at Saab Avionics AB in Järfälla, north of Stockholm. In order to investigate the performance of this new module XSG to simulink, a model of a frequency estimator often used in digital radar receivers were implemented in Matlab using XSG.

Det levande biblioteket ? retorik kring fördomar och möten. En argumentationsanalys i relation till folkbibliotekets mångfaldsuppdrag.

The living library started in Denmark at the festival of Roskilde in 2000. It was initiated by the youth organisation ?Stop volden? (?Stop the violence?). Since 2005 the idea of lending a human being who represents a prejudice has also become a practice in a few public libraries in Sweden. I found it interesting to analyse the living library in relation to the mission of diversity in the public library.
