Transport is an important aspect to take account in efforts to achieve sustainable tourism development. If we do not change our behavior regarding travel, the consequences will be significant for the environment. This study examines the various transport operators on the two Swedish ski resorts if their websites and marketing are different from each other in the mode selection. The destinations are Åre and Hemavan Tärnaby. They studied modes are two Swedish airlines, two train companies, three bus companies and three taxi companies.These corporate websites are studied with a content analysis in which the results of the keywords that have been developed are scored according to different categories.

The main purpose of this study is to clarify the underlying reasons as to why people choose to travel by car or taxi, and to do so by using people´s choice of transportation to and from Arlanda Airport as an example. Furthermore it is also in our interest to see what changes are needed to make more travellers use the available public transportation.Because of the increasing pollution rate from the means of conveyance headed to and from Arlanda Airport, Luftfartsverket is attempting to decrease the amount of emission from the connecting transportation sources. Luftfartsverket has a pollution limit which is about to be reached in a few years, based on a prognosis made by Arlanda´s office of environmental issues. In order to investigate people´s travel mode choice a survey was conducted at Arlanda Airport, Stockholm. 82 travellers were interviewed on a three day basis inside terminal 4 and 5.

Introduktionen av AJAX har möjliggjort skapandet av dynamiska webbapplikationer på Internet. Dessa dynamiska webbapplikationer bygger på att skicka data mellan klient och server med hjälp av asynkrona förfrågningar. Detta görs med hjälp av ett serialiseringsformat som används för att kompaktera data och möjliggöra kommunikation mellan olika programmeringsspråk. Binära serialiseringsformat har konsistent visat sig prestera bättre än de textbaserade alternativen på plattformar som tillåter binär transport av data. AJAX är en plattform som endast tillåter textbaserad transport av data.

This report is a thesis for collegeengineering program in structuralengineering at Uppsala University andwas commissioned by the Swedishcontractor Svevia. The study aims toprovide an overview of the mostbeneficial bridge material from bothenvironmental and economic point ofview.The life-cycle analysis covers onlycarbon dioxide emissions, since it isthe most spoken of in today?s climateagenda. Furthermore, this study aims tohighlight which parts, of the systemboundary, that contributes to greatercarbon emissions for the wood- and theconcrete bridge.The life-cycle cost analysis wascalculated with a lifespan of 40 yearsand covers the basic cost of investment,operating and maintenance, anddecommissioning costs.The analyzed constructions in this studyare existing projects that are almostcompleted. Both bridges were designed tohandle loads up to 60 tons.

Examensarbetet har genomförts i samarbete med Meritor HVS AB i Lindesberg som tillverkar fram- och bakhjulsaxlar till buss- och lastbilsindustrin. Projektet behandlar de fixturer som används vid transport av bakhjulsaxlar. Målet med arbetet var att utveckla en ny transportfixtur som passar majoriteten av deras bakaxelmodeller och som förebygger skador vid transport.Projektet har genomförts enligt metodiken systematisk konstruktion som beskrivs enligt Johannesson, Persson och Petterssons (2004). Systematisk konstruktion kan delas in i fem steg: produktspecificering, konceptgenerering, utvärdering och val av koncept, detaljkonstruktion samt slutkonstruktion.De problem som Meritor har med transportfixturerna är att de i hög grad slits och att skyddsbeläggningarna inte håller. Det finns för projektet 30 aktuella bakaxelmodeller som skall kunna transporteras med samma fixtur.

Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.

En sänkning medför ett friare vägval och billigare transporter. Hittills har vägvalet påverkats av broar, viadukter och andra hinder. Med hjälp av riktlinjer från Svedala Compaction Equipment AB och Fredy Olssons modell för integrerad produktutveckling togs kriterier fram, vilka användes vid bedömning av olika lösningsförslag. Utvärderingen resulterade i att två av de tio ursprungliga förslagen gick vidare till nästa steg i produktutvecklingsprocessen - primärkonstruktion. Primärkonstruktionen inleddes med vidareutveckling av de två principförslagen.

A great amount of todays drivers? are constantly exceeding the speed limits on the roads. As a consequense of this, a large number of speed redusing devises, for example speed bumps, has been built around the country. As reports in local medias point out, the acceptance for these types of speed reducing devises, differs and there are many thoughts about location, construction and effect on the traffic safety. This paper approaches the complexity of these problems from the drivers? point of view, based on literature studies and a questionnaire. The goal is not to argue for or against speed reducing devises, but to try to find the source of annoyment and how to proceed further. Some of the problems turned out to be easy to fix, for example porly marked speed bumps.

Arbetet har utförts i syfte att belysa möjligheten för Sjöfartsverket att använda helikopter istället för att allokera lotsar med lotsbåttransport till fartyg. Detta har gjorts i ett ekonomiskt perspektiv genom att använda Payback-metoden. Metoden har använts explorativt där det ekonomiska underlaget från nuvarande verksamhet vid allokering med lotsbåt jämförts med de beräknade kostnaderna för Sjöfartsverkets SAR-helikoptrar om de utför samma transporter. Ingen vikt har lagts vid vilka eventuella processförbättringar detta skulle kunna leda till, utan enbart vad kostnaderna för samma transporter skulle bli med det nya transportsättet. Resultatet har tagits fram utifrån tre aspekter: Hur det ses från lotsningens sida, hur det ses från helikopterfunktionens sida och slutligen vad det kommer att innebära för Sjöfartsverket som helhet.

When the producers? responsibility for packaging was introduced in Sweden in 1994 the industry set up public recycling stations to facilitate the collection of the waste material. In order to establish recycling stations at suitable locations the municipalities assist the industry?s service organization for operation of the recycling stations, the Package and Newspaper Collection Service (Förpacknings- och tidningsinsamlingen, FTI). The objectives of this thesis are to improve the service of the public recycling stations within Lidingö town and to increase the accessibility to these stations for the inhabitants of Lidingö.

The Swedish government has a goal of achieving a fossil-free vehicle fleet in 2030. Heavy transport constitutes a significant part of Sweden's transportation sector and the vehicles are driven almost exclusively by fossil fuels. Siemens has developed eHighway, a concept for electric road systems enabling electrification of trucks, in order to reduce the environmental impact of heavy transports. This study aims to investigate the potential that eHighway has on transporting iron ore from the mine of Mertainen to a processing plant in Svappavaara. Electrified trucks are compared with conventional trucks, and diesel and electric trains.The evaluation was made with respect to energy consumption, environmental impact, and cost.

This case study's aim was to strengthen the state of knowledge about how horticultural companies in Sweden used railway transports between 1900s and the 1950s. Economic theories and a micro-historical perspective have been used to analyze the collected source material, and to describe Lindehult's market garden. The investigation is based on document analyzes, qualitative interviews, archive studies and literature studies to evaluate the sources' information through a source pluralistic method. The work has been based on historical source material in the form of payment vouchers, giving an insight into how the company's products were transported by rail across Sweden. Sture Hjalmarsson's diary and interviews have described the case and events that affected the company internally.

Swedish agriculture has gone through big changes in the latest 60 years. The farm sizes have increased, which has led to raised tractor and machinery sizes and therefore increasing problems with soil compaction. A method to reduce these problems is to implement controlled traffic farming, CTF. All field operations are then concentrated to specific tracks by using GPS guidance. The aim of this work was to study how the tillage regime, with or without CTF, affects the soil, with the main focus on macroporosity. In Säby close to Uppsala, and Alnarp close to Malmö, randomized block trials has been carried out, and the data has mainly been taken from these trials.
