I sökandet efter gas och olja är allt tillåtet! : En kvantitativ innehållsanalys av Lundin Petroleums framställning i Dagens Nyheter.

 I sökandet efter gas och olja är allt tillåtetSyfte: Det övergripande syftet med denna studie är attbesvara frågan om hur gas- och oljebolaget Lundin Petroleum skildrats i Dagens Nyheter under ett års tid. Syftet fullgörs genom att studera samtliga artiklar från den avsedda perioden då Lundin Petroleum uppmärksammades för att eventuellt begått brott mot mänskliga rättigheter.Teori: Studiens teoretiska utgångspunkter är indelade i tre kategorier. Den första teorin innefattar den dramaturgiska aspekten, huruvida det i artiklarna förekommit värdeladdade ord i samband med Lundin Petroleum för att förstärka eller dramatisera artikelns information. Den andra teorin innefattar den journalistiska aspekten, det vill säga hur trovärdigt artiklarnas innehåll är i relation till artiklarnas källhänvisning, och i relation till vem som skrivit innehållet. Den tredje teorin baseras på nyhetsvärde, och avser urskilja vad för vikt eller relevans en artikel kan tänkas ha för deras läsare.Metod: Uppsatsen bygger på en kvantitativ innehållsanalys utförd på 76 artiklar från 2011-01-04 till 2012-03-27.

ALTERNATIVA ASFALTSBELÄGGNINGAR : Möjligheten att använda icke petroleumbaserade bindemedel

This report investigates the possibility to use non-Petroleum based adhesive (biobitumen) in asphalt. The main reasons for replacing bitumen are the fact that oil prices are rising, the threat of peak oil and the fact that the asphalt industry is becoming more environmentally friendly.The main purpose of this report is to investigate whether there are any non-Petroleum based adhesives on the market. If so, how can they be used? The questions covered are:? Are there any other alternative asphalt coatings available?? Can bio-oils be used in asphalt?? If the bio-oils can be used, what are the details their properties?? How does a cold climate affect the bio binders?? What is the Swedish asphalt industry?s opinion about bio asphalt?The project was concluded through literature studies, consultations with people in the asphalt industry and through several interviews.The conclusion of this report is that there are some existing non-Petroleum based adhesives on the market. They are mainly used for bike paths, sidewalks and parkareas.

Sapa Heat Transfers koldioxidspår : En kartläggning av verksamhetens koldioxidutsläpp

Sapa Heat Transfer is a company that produces aluminum heat-exchanger strips for the automotive industry. Sapa Heat Transfer wish to chart their emissions of carbon dioxide in order to meet future demands on carbon dioxide reporting. They also would like to examine the meaning of the term ?green electricity? which is marketed as carbon dioxide free, and the sort of electricity that they purchase. This report includes both direct (liquefied Petroleum gas and diesel) and indirect (water, process-water, long distance heating, waste) emissions from their company.

CARL BILDTS BEMÖTANDE AV JÄVSANKLAGELSER PÅ TRE OLIKA MEDIALA ARENOR ? EN RETORIKANALYS

In July 2011 the journalists Martin Schibbye and Johan Persson are arrested in Ethiopia when on a mission to report the activities of the oil exploration company Lundin Petroleum. Following a trial, closely observed by media, the two journalists are convicted to a prison sentence of eleven years. The Swedish Minister of Foreign Affairs, Mr. Carl Bildt, is now to act on their behalf to preserve their rights as Swedish citizens. However, doubts are raised as to whether Bildt has a conflict of interest because of his former engagements as a board member in Lundin Petroleum.

Återvinning av blandmaterial : Polyamid och Polyester

Om människor fortsätter med det konsumtionsbeteende som råder idag kommer jor-den resurser ta slut. Den fossila råvaran Petroleum används vanligtvis vid framställ-ning av polyester och polyamid. Petroleum har en 100 000 årlig process, vilket är en ofantlig skillnad i förhållande till den takt som det förbrukas. Därför har eventuella möjligheter att återskapa en ny filament av återvunnet syntetiskt blandmaterial un-dersökts i detta arbete.Det finns befintliga metoder för att återvinna polyester och polyamid som homogena material. Dock vid återvinning i en gemensam process av materialen får den slutliga produkten en försämrad kvalité.

Liquid diesel biofuel production in Sweden : a study of producers using forestry- or agricultural sector feedstock

The transportation sector is the only sector of the Swedish society that is still increasing the emissions of carbon dioxide and other green house gases. Diesel fuel represents one of the fuels that contributes to these emissions and the use of diesel fuels is increasing every year. The main purpose of this study was to make an estimation of the current business situation for producers of liquid diesel biofuels in Sweden such as biodiesel, synthetic diesel and crude tall diesel and examine the forces of competition of the industry today and its future prospects. The study revealed that the rivalry among the existing firms was low mainly due to the geographical spread of the companies. Moreover the success of the biodiesel industry was influenced by a long-term guarantee of the tax exempt for biofuels and by the price level of Petroleum diesel.

Beyond Petroleum : Strategier i BPs pressmeddelanden och dess avtryck i svensk morgonpress

Denna uppsats behandlar ämnet kriskommunikation. Olika kriskommunikationsteorier presenteras och tillämpas i fallet med oljejätten BPs oljekatastrof i Mexikanska golfen, våren 2010. Pressmeddelanden från företaget analyseras för att urskilja strategier utifrån teorin image repair och även svensk morgonpress granskas för att se hur väl BPs kriskommunikation återspeglas i nyhetsrapporteringen. Teorin image repair som vi använder oss av i vår studie är utformad av William L. Benoit.

Jämförelse av metoder för peroxidbestämningar i bränslen : A comparison of methods for determination of peroxide content in fuel

New energy resources that can replace Petroleum diesel are needed and biodiesel may be an excellent substitute. During storage and use, biodiesel can oxidize and form peroxides, leading to degradation of the fuel. It is therefore important to determine the peroxide content of the fuel. In this thesis the triphenylphosphine method, which involves GC-MS analysis has been compared to the standard iodometric method which involves titration with sodium thiosulfate. Working standards were made to see how well the iodometric method worked and also in order to make a calibration curve in GC-MS.

Radialtätning till Retarder

This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. It has been found that carbon residue formation may occur between retarder axle and seal lips with, in some cases, leakage as a result.We have in this thesis tried to explain the phenomenon of carbon residue, how it is formed and why it can be seen just on the seals? A rig test was conducted where we show how friction, speed, transmission temperature and mitigation phases of the retarder affects temperatures in the sealing environment. Factors affecting the coke structure are reported, together with proposals for measures that provide a mitigating seal environment.

Transferfunktionsmodeller modellering och prognoser av Sjötransportindex

We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of Petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.

Grön olja? - En fallstudie av ett oljebolags miljöprofilering

While the call for regulations against greenhouse gas emissions are louder then ever before, demand for oil is also at an all time high. Oil companies face the dilemma of making sound business without being perceived as environmental villains. In this essay I will examine how BP, one of the largest companies in the world, broke rank with the industry and devoted itself to being an environmental friendly oil company. The actions and motives of this change will be evaluated through up-to-date theories about company motivation to environmental adaptation. We see that BP:s transformation can be well explained through Simone Pulvers theory about the socially embedded company.

Svenskt tullskydd. En studie av svensk protektionism under trettiotalet.

This paper attempts to study the Swedish tariffs during the interwar period in order to asses the level of protectionism in Swedish tariff policy during the period. It is foremost the nominal tariffs that are studied, however an estimate of the effective rate of protection of the tariffs is also calculated for a number of goods. In order to asses the level of protectionism, the Swedish tariffs are also compared with Finnish tariff levels during the interwar period.The sample of Swedish tariffs that have been studied in this paper include the fifteen most important kinds of import goods and the fifteen most important kinds of export goods. The nominal tariff of each kind of goods have been weighted by their share of the total import value.The Swedish specific tariffs did not change much during the interwar period except for a few goods such as Petroleum, coffee and automobiles. The fluctuation in nominal tariffs were in most cases the result of the steep fall in prices during the period.

Toxicitetsanalys med luminescenta bakterier: undersökning av yt- och grundvatten från Gällivare bangård

Examensarbetet har utförts på uppdrag av Banverket Norra banregionen. Syftet var dels att identifiera vilka föroreningar som finns på Gällivare bangård, dels att få en uppfattning om toxicitetstest, främst bioluminescenta test och att utföra en screening med vatten från Gällivare bangård med ett bioluminescent bakterietest. Försök gjordes även med en metallösning av koppar och PAH-förorenat vatten samt en blandning av koppar och PAH. EC50-värden efter 15 och 30 minuter har beräknats för de vattenprov där så varit möjligt. Vattnet från Gällivare bangård analyserades på laboratorium för att om möjligt kunna identifiera vilka eller vilket ämne som ger upphov till eventuell toxicitet.
