A recent development in the field of accounting has been an increasing use of fair values in financial reporting. In 2005, this development was reinforced in Sweden by the adoption of the International Financial Reporting Standards. The aim of this thesis is to discuss the problems related to the use of fair values, through a case study of the Swedish investment bank Carnegie. In May 2007, Carnegie announced that the result had been overly stated by 630 MSEK, due to the valuation of derivatives within the trading department. The empirical material consists of documents produced in the legal process between Carnegie and the Swedish Financial Supervisory Authority.

The 3:12-provisions are part of a legal system specified for owners of close corporations (companies owned and managed by a small group of businesspeople), for taxation of capi-tal gains and dividend. The reason for special rules for the taxation of these owners is to prevent them from transforming their income, to only be subject of the lower taxation of capital gains, instead of income of service. Since the rules were put in force, they have been subject to several changes. The most recent changes took effect on the 1 January 2006. They involve a higher importance for the rule of salary-based taxation.

Turkey?s nearly fifty-year-old aspiration for admittance to the European Union took a crucial step forward with the signing of the Ankara agreement in 1996. The aim of this thesis is to examine the trade effects that evolve from the creation of a customs union. Our objective is to study how Turkey?s trade patterns adapted to the liberalized trade by examining the effects on resource allocation, specialization and welfare.

Utgångspunkten för uppsatsen är den traditionella teorin om marknadseffektivitet som ställs mot tidigare forskning, främst amerikansk, och den moderna beteenderelaterande finansiella teorin. Bland annat diskuteras studier av Jaffe, J., Finnerty, J., Fama, E. samt Lakonishok & Lee. Den teoretiska referensramen ligger till grund för författarnas egna hypoteser som testas med hjälp av statistiska analysmetoder. Strävan har varit att utifrån resultaten antingen kunna stärka eller försvaga tilliten till tidigare forskning vars slutsatser varit att det är möjligt att skapa överavkastning genom att imitera insiderhandeln.

Abstract: The purpose of this study is to examine whether companies listed at Nasdaq OMX Stockholm (Stockholmsbörsen) sanctioned by the legal unit Nasdaq OMX Disciplinary Committee (Disciplinnämnden), could be distinguished from the remaining companies that have not been sanctioned. As Stockholmsbörsen is the most influential unit when trading shares in Sweden, listed companies need to behave in legal aspects. Actions and decisions that affect investors do also influence the listed companies and their performance. Some companies might be tempted to manipulate financial statements and public information to retain stakeholders; other miss to report properly without being fraudulent. To control this, the legal unit Disciplinnämden is introduced.

The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.

A large part of the agricultural products that are sold in Sweden are imported because Sweden cannot meet the consumers agriculture products demand all year around. One problem that can occur and become problematic when trading across boarders is if there are errors in the delivered agricultural products. What must the Swedish buyer do, for example, make for it to be considered complained fault in the goods against the seller? Another problem in international trade is that the buyer may need to apply complaint rules they have not previously been in contact with since their domestic law is not always applicable to the contract. To avoid getting into this situation, the buyer should try to negotiate with the seller that the contracting parties shall use compensation claim rules that the buyer is familiar with, or which is even more advantageous than to the seller.

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

Trade is the driving force for economic development. A greater equity in international trade can improve the livelihoods and the well being of producers in developing countries. The small-scale farmers have limited resources and have difficulties to get access to the international market. As a result of this, the Fair Trade movement has been developed and has now formed a trading partnership between the producer and the consumer. This study analyses if the Fair Trade movement can be a way for the workers in developing countries to achieve more justice in their production manner in the international trade of cut flowers and continue to be an important competitor of these products, but with better livelihood conditions. My method has been to do a comprehensive literature study of the Fair Trade movement, in which I describe the certification process, and the market of Fair Trade in Sweden.

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

The main environmental problem for aviation is the great amount of exhaust gases, mainly nitrogen oxides, carbon monoxide, carbon dioxide and hydrocarbons - mostly "greenhouse gases" leading to climate changes. I decided to sort out what is being done to decrease these problems and what regulations there are concerning air pollution by the means of searching the internet and using publications from aviation authorities for current figures. I chose to scrutinize authorities on political, authority and company level, resulting in summarizing the work of UN and EU respectively, ICAO (International Civil Aviation Organization), JAA (Joint Aviation Authorities) and LFV (Swedish Civil Aviation Authority), and finally SAS, representing the airline companies. Conclusion that I have drawn are thatthere are regulations for air pollution, written down in ICAO's Annex 16, that are to be followed. Secondly, LFV are environmentally controlling their nineteen airports and since economy is an important reason for not giving priority to environmental issues in aviation emission charge and noise charge are added to the landing fees.

Kinetiken för nitrering av en järn-kromlegering med en gasblandning av ammoniak och vätgas har studerats vid temperaturer mellan 500°C och 600°C. För ett gasatomiserat pulver (Fe-7%Cr) har inverkan av syrepotential (H2O/ H2) och olika förbehandlingar (förreduktion och förnitrering) studerats med hjälp av en termogravimetrisk metod. Dessutom har laserablering som förbehandlingsmetod för nitrering av solida ytor studerats med hjälp av GD-OES-analys (Glow Discharge Optical Emission Spectrometry). Resultaten har diskuterats och tolkats med avseende på faktorer som kan påverka ytreaktionens hastighet, kärnbildningsförhållanden samt diffusionsvillkor. Syrepotentialen har visats påverka nitreringshastigheten via komplicerade samband mellan syrepotentialens storlek, kvävehalt i materialet och nitreringstemperatur.

Purpose: The main purpose of the thesis is to examine the profitability of Momentum Strategies on the Nordic stock markets. This will provide insight and contribute to the debate on efficient markets. Finding profitable Momentum Strategies will provide strong evidence of inefficiency in the market. A secondary purpose is to examine factors which might cause or impact the profitability of the Momentum Strategy. We will look closely at the relationship between the profitability and factors such as risk (CAPM-beta), market capitalization, trading volume and seasonality.

Då giraffens föda utgörs endast av blad, löv och knoppar, trots att det är den största idisslaren som lever idag, har dess anatomi genomgått en serie av anpassningar för att kunna överleva på denna föda. Till det yttre har den under evolutionens gång utvecklat en otrolig längd som gör att den når långt upp över alla andra idisslare, och till det inre har dess mag-tarmsystem anpassat sig efter födans egenskaper. Giraffens huvud har en avlång form och behåring på läpparna som ska skydda den från trädens stickiga försvar, en tunga som kan bli upp till en halvmeter lång, och tuggmuskler som har anpassats till den relativt lättuggade maten. Förmagarna har i sin tur minskat i storlek och kraft och fått ett anpassat utseende och utbredning på dess papiller, och tarmen har en liten ratio tunn/tjocktarm. Giraffens cirkulation har fått anpassa sig till stora höjdskillnader, då giraffen kan sträcka sig upp till ett träd och bli mer än fyra meter lång, men i nästa stund böja sig ner för att dricka vatten på marknivå. Som följd av dess längd har dräktiga och lakterande honor, samt växande ungdjur, en väldigt hög kalcium- och fosfatomsättning i kroppen och kan därför lida brist på dessa mineraler. Den drivande kraften bakom giraffens längdutveckling har länge sagts vara övertaget den ger vid födosök, men det finns även en annan teori som baserar sig på att den drivits av sexuell evolution..

Bakgrund: Börsen ger en möjlighet för företag att erhålla kapital och för placerare atttillgodogöra sig avkastning. Personer med insyn i det egna företaget, så kalladeinsiders, kan dock i egenskap av sin position inneha kurspåverkande information somövriga aktörer på marknaden inte har möjlighet att ta del av. Tidigare forskning harpåvisat att insiders utnyttjar denna informationsasymmetri för att på så sätt tillgodogörasig överavkastning.Syfte: Syftet med studien är att undersöka om insiders kan tillgodogöra sigöveravkastning genom handel med aktier på Nasdaq OMX. Vidare ämnar studienutröna eventuella skillnader i överavkastning beroende på företagsstorlek,transaktionsstorlek samt tidsperiod.Metod: I denna studie har en kvantitativ forskningsstrategi i form av en eventstudietillämpats. Studien har en deduktiv ansats och undersöker insidertransaktioner från 90företag på stockholmsbörsen under tidsperioden 2006-01-01 till 2011-12-31.
