86 Dagar 16 timmar 25 minuter : En kvantitativ innehållsanalys av nyhetsbevakningen kring oljeutsläppet i mexikanska golfen 2010

Purpose: When the Deepwater Horizon oilrig in the Gulf of Mexico faced disaster in late April 2010, news coverage immediately began of the disaster that would unfold. BP took the blame and its financial resources were strained as it struggled with stopping the oil leak, cleanup work as well as its PR image. While the US took many blows of the consequences to ecosystem and tourism, financial consequences swept across the world, mainly Britain, where BP had its headquarters.The event gives an excellent chance at comparing the media coverage from both the US and Britain. By studying The Daily Telegraph and The New York Times, we want to see both similarities and differences in the themes they focused on as well as seeing trends in the themes over time.Theories: The theory chapter is heavily based around the Agenda-setting theory in the media communication field.Methodology: A quantitative content analysis (QCA) of some 500 news articles in The Daily Telegraph and The New York Times from April 22 to July 15. The QCA was made to find the main theme of articles to give us data on how many articles of each theme, as well as their distribution over time.

vindkraftens påverkan på elkvaliten

This thesis concerns how the power quality in the grid is affected by the connection of wind power plants. As things are at present, Fortum Distribution AB has a number of wind turbines and wind parks connected to the own grid. As the pressure on building and connecting additional wind power is increasing, so is also the interest of how the already existing wind power generation affects the power quality in the nearby distribution grids. The study is performed by direction of Fortum Distribution AB and is limited to the 10 kV/40 kV-grid in Bohuslän, Sweden. The methods for calculation of power quality are compared to the results of a number of measurements.

Sälj innan köp! : En studie om hur spelarövergångar påverkar fotbollsklubbars aktiekurs

Pengarna rullar allt snabbare inom fotbollen och från Southampton säljs de båda tonåringarna Theo Walcott och Gareth Bale för £5 miljoner styck. Båda de händelserna följdes av ett kursfall för Southamptons aktie vilket skulle kunna tolkas som att marknaden inte tyckte det var goda nyheter. Detta leder oss till vår problemformulering:Hur påverkas börsnoterade fotbollsklubbars aktiekurser vid spelarövergångar?Syftet med uppsatsen är att undersöka om det finns en avvikande avkastning i samband med en spelarövergång. Vi undersöker även om det är någon skillnad mellan spelarköp och spelarförsäljningar.

Ammoniumåterkoppling på Himmerfjärdsverket ? utvärdering genom försök och simuleringar

Avloppsreningsverk står inför uppgiften att rena inkommande vatten för att möta lagstiftade gränsvärden till en så låg kostnad som möjligt. Att syresätta biologiska reningsprocesser är kostsamt eftersom luftningsanordningen förbrukar mycket energi. Ungefär en femtedel av Himmerfjärdsverkets totala elenergiförbrukning går till luftning av biologiska processer.För att öka Himmerfjärdsverkets energieffektivitet startades under 2010 experiment med olika strategier för luftflödesstyrning. En av verkets nitrifikationsbassänger byggdes då om för att möjliggöra zonvis reglering av syrehalten.Syftet med denna studie var att utvärdera reglering med ammoniumåterkoppling och syrehaltsprofil för styrning av Himmerfjärdsverkets nitrifikationsprocess. Utvärderingen baserades på reningsresultat och energiförbrukning.Med nuvarande reglerstrategi varieras luftningen genom återkoppling från syrehalten i den andra av sex zoner i varje luftad bassäng.

Managerbyte? : En studie av aktieprisets reaktion när fotbollsmanagern lämnar klubben

I februari 2006 avskedas Graham Souness från Newcastle United efter en tids dåliga resultat. Den dagen han avskedas tar aktien ett skutt uppåt, således tyckte marknaden det var bra att han avskedades trots att det innebar ökade kostnader för klubben. Med detta som faktum uppstod vår problemformulering:Hur påverkas börsnoterade fotbollsklubbars aktiekurs när managern lämnar klubben?Syftet har varit att undersöka om det förekommer avvikande avkastning när en fotbollsmanager lämnar klubben. Vi har också gjort en jämförelse med hur det ser ut när VD: n lämnar ett företag.

Ett företag i det socialt oacceptabla

Den svenska MMA marknaden är idag under hård kritik. Många människor menar att det endast är kriminella som håller på med kamsport och att de tävlingar som arrangeras är ren brutalitet. Trots det här så har vi idag väldigt stora aktörer på den svenska marknaden som inte bara klarar sig utan även växer. Men organisationerna har fortfarande den allmänna opinionen emot sig. Företagen försöker att framstå som så sportsliga och godartade som möjligt och de menar att MMA inte är våld utan en idrott.

Nollföljdsmodellering av transformator-Beräkningar av följdproblem vid ökad kablifiering på mellanspänningsnivå

Historically transformers with system earth equipment have been modeled as open circuits in zero sequence. This approximation has been satisfying, but lately it has been discovered that equipment on one side of the transformer have responded to faults that occurred at the other side. Most of these problems took place when the majority of the system on the secondary side of the transformer contained cables. These findings have led to questioning whether or not the former model of the transformer in zero sequence is correct. This report investigates if it is necessary to represent the transformer in zero sequence in another way than it is usually done today.

Incidenter på svenskt sjöterritorium : En analys av de åtgärder som vidtagits vid incidenter orsakade av Öst- respektive Västblocken under 1960-talet

Sweden has long been nonaligned in peace with the aim to remain neutral in the event of an outbreak of war. Building confidence for this neutrality was important for Sweden during the Cold War. This placed high demands on the Swedish Navy to detect and repel violations of Swedish territorial waters. The archives, which contain the secret reports on the violations that occurred during the 1960s, have recently been opened up.The purpose of this essay is to study how the incidents that took place in Swedish territorial waters in the 1960s were managed and to examine if the handling of them was different depending on whether they were caused by the east or west side. Furthermore, the aim is also to try to categorize and interpret these measures from the two pairs of concepts of deterrence and reassurance and integration and screening.In making it possible to answer the questions, all the reports - 66 altogether - which refers to the incidents which occurred during the years 1962 through 1969, have been studied.

Att förhålla sig till den nära historien - och planera för den avlägsna framtiden :

This thesis concerns the term contemporary history and its role in landscape architecture. Today?s contemporary history is defined as the planning and architecture connected to the 60s and 70s, in Sweden carried out as a large scale planning project called ?Miljonprogrammet?, which set out to build one million new residences in ten years. Initially, the term contemporary history and its complex of problem are examined. To deepen the picture of today?s situation, a historical review has been made, starting in early 1900s ending in 2000s concerning how different planning and architectural influences has varied through the years.

Simulering av elektriska förluster i en vindkraftpark : Utveckling av programvaran Wind Farm ElectricSystem Calculator (WFESC)

When planning new wind farms, the cost for the internal electrical grid is estimated to account for 8-9 % of the total investment cost. On top of that, the cost for accumulated reduced income over several years (due to electrical losses), has to be added. The economic lifespan is relatively long (about 20 years) which means that an error in the loss calculation could lead to a bad decision basis. The accumulated reduced incomes due to electrical losses can be higher than the initial investment cost for the internal electrical grid.Today, Statkraft Sweden is using a template number when estimating the electrical losses in a wind farm. The actual losses are probably lower than the template number which could lead to an unnecessary high loss cost when planning a new wind farm.The aim of this M.Sc.

Lönsamheten i vindkraft : en studie om den förväntade lönsamheten i landsbaserad vindkraft

This thesis analyzes the expected profitability in land based wind power plants. The expected profitability is calculated on the basis of a wind power project in Vartofta, Falköping. The information required to calculate the expected outcome is then concentrated to this project, which is in this thesis called project Näs. In project Näs they plan to build three wind power plants, with each an effect of 2 MWh. These wind power plants are very capital intensive investments with a long and uncertain payback time.

Bostadsrättssäljarnas kriterier vid val av fastighetsmäklare

Every year a number of tenant-owner flat deals are concluded and the availability of real estate agents on the market is today very widespread. It has become increasingly difficult for estate agents to distinguish themselves in a way that makes the estate agent the customer?s choice. Estate agents must have a good understanding of what is important to the customer. An apartment deal is, for most people, an important event in their life.

"Spelar roll" : -En studie av Folksams kunders varumärkesuppfattning

Variations in fertility have caused a problematic situation in Sweden among other European countries. According to the Council of Europe we are facing an economic and demographic challenge, when the baby boomers of the 1940?s are retiring. Economists have for a long time studied the connection between economic factors and fertility, and several studies have found a correlation between business cycles and birth rates. This connection is again of current interest 2008, when a financial bubble bursts at the same time as a baby boom occurs.
