When the emissions from the diesel trucks today accounts for a large part of the total emissions from the road traffic, the trend with a more extensive use of diesel trucks for transportation will therefore lead to increasing carbondioxide emissions to the atmosphere. Because of the fact that technical progress in the form of optimized engines and shifts in the means of transport sometimes result in even greater emission levels, other solutions to this problem must be studied to decrease the emissions of carbondioxide from the diesel trucks. The purpose of the thesis is to show how a decrease of the carbondioxide emissions from diesel trucks in Sweden can be achieved in a costeffective way by the use of a carbondioxide tax and a differentiated vehicle tax. The method used in order to fullfill the purpose of the thesis is studies of literature, mainly of public government reports. Literature of enviromental economics will be used to show the need of a tax and how to determine the dynamic effective carbondioxide tax in steady-state.

Background: The increasing number of actors on the market has led to a more intense competition among superstores. With this, marketing has gotten an even more essential meaning. The marketing activities superstores perform are adapted to the context in which the store is located. Purpose: The purpose of this thesis is to, from different theoretical dimensions, compare superstores? application of marketing strategies in Tokyo with the marketing strategies used by superstores in Stockholm.

Urbanization has for a long time been a threat to our biodiversity. Epiphytic organisms such as lichens have been negative affected by traffic pollution and the new urban environment surrounding their old habitat (van Her 2001). Another epiphytic organism is the green algae Desmococcus olivaceus. Unlike lichens the green algae is favoured by polluted areas. The aim of this study was to investigate if time in urban environments affected the cover of the green algae on old oaks.

Offentliga trådlösa nätverk finns idag mer tillgängliga än någonsin. Samtidigt haralla dessa nätverk något gemensamt ? de går alla att avlyssna och risken finns attanvändarens information kan komma i fel händer. Uppsatsen behandlarallmänhetens säkerhetsmedvetenhet med avseende på denna typ av nätverk genomtvå undersökningar. Den första undersökningen sker via ett tekniskt experiment därdet på flera geografiska platser har erbjudits ett trådlöst nätverk till allmänheten.

Tasmania is a state in Australia, and is also the country?s largest island. It is separated from the main land by a 429 kilometer wide strait. Every year, a large amount of people, cars and goods are transported to the island using a government owned ferry line, which generates approximately 300 million Australian dollars to the state?s economy ,every year. This bachelor thesis investigates the possibility of reducing the fuel consumption for the ferry traffic to and from Tasmania, which would also reduce the overall cost.

The purpose of this essay is to investigate how well vision and strategies communicates from division level to underlying business unit levels with focus on the Balanced Scorecard Concept. The investigation was carried out within the ANS division and two of its underlying business units at the LFV Group (Swedish Airports and Air Navigation Services). ANS is responsible for the air navigation services in Sweden and the production of the services is carried out of the business units AER (En Route) and ATA (Tower and Approach). With Air Navigation Services means supervision and conducting air traffic mainly within national air space. The purpose of the services is to insure that air traffic could be carried out in a safe way.The Balanced Scorecard was introduced for the first time in the beginning of the 1990´s.

When communications traffic increasingly turned into data, IP telephony became a disruptive technology for the telecommunication business. IP telephony was a hot topic when voice over IP services started to become available to consumers in the 1990s. The new technology changed the rules of the game and many new actors entered the market.The purpose of this study is to describe, study, and analyze how the business models of the Swedish telecom sector developed in the middle of the 2000s. The study is delimited to the Swedish consumer market for telephony.The study is built mainly upon deep interviews with 24 prominent persons in the telecom sector in 2006. To aid understanding, two telecom companies that have been chosen to represent different kinds of actors are described and analyzed more closely.

In April 2010 Vägverket (the Swedish National Road Agency) andBanverket (the Swedish National Railway Agency) will merge intoTrafikverket (the Swedish National Traffic Agency). Trafikverket willassume unified responsibility for the risk management that atpresent is responsibility of Vägverket and Banverket separately. Atpresent, as it will be shown in this thesis, Vägverket and Banverketshare the same theoretical background for risk management but usedifferent implementations often within the same agency. The use ofdifferent implementations results in a reduced transparency of therisk management both within and outside the agencies: this willbecome even more problematic when they will be fused intoTrafikverket.The aim of this thesis is to review the current risk managementmethodologies used at Vägverket and Banverket and to suggest aunified tool for the risk management at Trafikverket. This will bedone by focusing in particular on construction projects, one fromVägverket (Partihallsförbindelsen) and one from Banverket(Nynäsbanan).

Storm water causes a number of problems in our country, particularly in city environment with its surfaces of non-absorbing ground materials. At heavy rain falls there are floods due to lack of capacity in the drain system when meeting heavy water masses over a short time. When the drain system is overloaded huge water masses reach the recipient untreated and there causing disturbances in the aquatic ecosystem. Due to emissions from mainly traffic, industries and other human activities the storm water is polluted. Earlier the problem used to be solved technically, by increasing the capacity of the tubes and by construction of reservoirs to delay the floods peaks.

Tjörns kommun har planer på att bebygga Almön, en halvö belägen på nordöstra Tjörn intill Tjörnbron. Projektet är avgränsat till området som benämns Almöstrand, vilket är Almöns västra strand, en kuperad sluttning med kraftigt lutande partier som idag till största del består av skogsmark. Syftet är att undersöka hur man på olika sätt kan planera vägsträckningen i området, samt placering och utformning av hus, med hänsyn till en rad olika parametrar. Undersökningen visualiseras slutligen i 3D, i form av renderingar från Revit Architecture samt en fysisk modell.Initialt genomfördes en utredning för att ge beslutsunderlag till projektet. Vidare gjordes en fallstudie vilken har använts som referens och inspiration till arbetet.

This study describes what impact activity within Wifstas, Matfors,Grönstas and Nolbys water protection areas have on the quality of the drinkingwater. It considers the use of the area, environmentally dangerous activitiesin the past and present, the geology?s part, what harm hydroelectric power damsmay cause if they break and how climate change might affect the area in thefuture. It also takes into consideration activities outside the waterprotection areas which might have a suspected impact on the water quality. Theresults of the study are that pollution from infrastructure such as roads, orwastewater from treatment plants may cause occasional contamination of thedrinking water, foremost due to flooding.

This is a bachelor?s essay in the landscape architect programme in Alnarp. The purpose of the essay is to describe discussions about security in planning contexts in Sweden. Written material from three levels of the discussions has been studied: Swedish research, governmental directives and practisers. I have tried to obtain a variation in types of material.

Swedish contract law is based on the main principle of freedom of contract, which means that a contract is built on a voluntary agreement of both parties. There are exceptions from the principle of freedom of contract. In some instances a party is obliged to contract (kontraheringsplikt), which also is the subject for this paper. Kontraheringsplikt can be described as an obligation for one of the parts in a relation to come to an agreement under normal circumstances with everyone who ask for it. The cases of kontraheringsplikt are rather different.
