The purpose of this thesis is to study whether there is a demand for sawn wood products of large dimensions and planed goods among Wallnäs AB:s customers. The thesis consist of two main parts, one survey among Wallnäs present customers and another one which purpose is to increase Wallnäs customer base. Finally there is a chapter that describes what properties the raw material has to have in order to produce the demanded products. The survey to the present customers was conducted through a questioner. A sample of those who stated an interest for either sawn wood products of large dimensions or planed goods, were later contacted for a telephone interview. To reach out to new customers, relevant companies has been identified through the Swedish Trade Councils data base and through the member list of the Timber Trade Federation.

Over an extended period of time there have been plans to establish a shared facility in Lennheden to extract groundwater from the Badelunda esker to provide drinking water for the cities of Borlänge and Falun. The city of Falun is dissatisfied with the quality of its drinking water and the city of Borlänge is concerned about the risk of contamination of its existing groundwater supply at its current location. To provide a basis for a decision on this issue, the company Midvatten AB has been commissioned to perform hydrogeological investigations in the area of Lennheden.The purpose of this thesis is to design a functional groundwater model of the area between Lennheden, place of planned extraction, and Övre Tjärna, place of existing extraction, to get a better understanding of the groundwater situation in the area. A groundwater model enables simulations of different scenarios in risk assessment and contaminant transport. The aim of the thesis is that the model can be used as an aid in Midvatten?s investigations in Lennheden and that it also can be used in future projects in the area.The model has been made in Processing Modflow 5.3 and encompasses an area of 19,5 × 11 km along the Badelunda esker and the river Dalälven between Djurmo and Frostbrunnsdalen.

To achieve the goal of fossil independency in the Swedish vehicle fleet in 2030, it would be important to substantially increase the proportion of electric vehicles, both BEV:s (Battery Electric Vehicles) and PHEV:s (Plug-in Hybrid Electric Vehicles). The Swedish Energy Agency has funded numerous research and development projects about electric vehicles in recent years. An important task for the Swedish Energy Agency is to allocate state funds to those projects with the greatest potential to contribute to increased establishment of electric vehicles in society. The purpose of this work is mainly to understand the efforts and measures that can make the market for electric vehicles to grow. The report can contribute to a better understanding of how far the research on electric vehicles has come and what has to be done in the future to promote the establishment of electric vehicles. Another aim for this report is that it should serve as a basis for future decisions by the Swedish Energy Agency on which projects that will be funded with state funds.

I detta examensarbete undersöks vad som lockar med bilen som vardagligt transportmedel hos invånare i Malmö. Som en del i detta, identifieras faktorer bakom valet av transportmedel. Malmöbors tankar kring sin egen miljöpåverkan samt vilka utmaningar vi står inför när det gäller att gå emot ett mindre bil-dominerat samhälle diskuteras. Metoden bestod i att genomföra samtalsintervjuer med sex personer som samtliga bor i Malmö och som har körkort och tillgång till bil. Resultaten tyder på att bilens attraktion består i de fördelar den tillhandahåller, såsom lastutrymme, sparad tid, frihetskänsla och oberoende.

The background to this paper is the events that have taken place in the Swedish area of responsibility in Afghanistan where Swedish troops have been ambushed by the insurgents. Although the troops primarily where riding in Toyota Land Cruisers they had no casualties. I think that the Swedish force needs other vehicles that can be armed and are armoured.When I compared three different types of armoured vehicles, I found that PTGB 6 is the vehicle of choice, according to the special needs that a Swedish EOD-squad, their task and their equipment have. .

As a company it is required to work with strategies to minimize costs such as packaging and logistic costs. The increased market of industrial produced wooden buildings results that the time and the cost which the packaging of prefabricated building elements consume, is experienced to be in greater need of development than before and demands a better solution. The aim with this dissertation was to discover how the development of the handling of the packaging can improve the packaging process. The goal was to present improvement proposals for a simplified and thereby a more efficient production in time and cost perspective.The packaging process which includes packaging, handling, storage and transport were studied. Interviews were made with participants from the market for manufacturers of wooden houses and a case study was made at the company A-hus.

We travel more nowadays. The increasing travel rate generates greenhouse gases which in the long run cause an increasing number of natural disasters over the world. Car traffic is a major contributor to this development. Out-of-town shopping centres have historically good accessibility for car traffic. This study aims to look into what are the factors that influence the choice of transport mode for dwellers in the outskirts of a town when going to out-of-town shopping centres.

Detta examensarbete är utfört åt Alnöbud och Transport i Sundsvall. Alnöbud och Transport håller påmed transport inom såväl Sundsvall som ute i landet. Deras tidrapporteringssystem var föråldrat och de använder sig idag av papper och penna för att registrera de olika anställdas tider. De ville dåveta hur man skulle kunna datorisera detta påett enkelt, smart och prisvärt sätt. Genom att gå till grunden för hur ett litet företag i dagens läge skulle kunna gå tillväga för att datorisera exempelvis ett sådant system krävdes genomgående information om allt från undersökningar, priser för liknande typer av kravspecifikationer och jämförande mellan olika produkter/tjänster.

In Sweden, the demand for bio energy has increased in recent years due to the current energy and climate debate. In 2008, the energy supply of Sweden was 612 TWh, biofuels accounted for 123 TWh of these. Stumps have been highlighted as a potential fuel in recent years and the Swedish Forest Agency expects a technically and biologically feasible potential of 20.7 TWh annually between 2010 and 2019. The idea of utilize stumps is not new. During the 19th century stumps were used for tar production and during the 70?s and 80?s attempts were made to use stumps in the pulp industry.

Inledning Intrahospitala transporter av intensivvårdpatient är ett ansvarsfullt arbetsmoment och en stor del av intensivvårdssjuksköterskans och undersköterskans arbete. Det är riskfyllt eftersom tillbud med patient och utrustning kan ske.Syfte: Syftet var att beskriva förekomsten av tillbud och typ av tillbud under intrahospitala transporter av intensivvårdspatienter, samt jämföra om det finns skillnader i förekomst av antalet tillbud under olika tidpunkter på dygnet och skillnad mellan akut respektive planerad transport. Syftet var också att undersöka sjuksköterskors och undersköterskors upplevda grad av stress och trötthet under transporten samt om det finns skillnad i förekomst av trötthet och/eller stress vid transporter där det sker tillbud respektive inte sker tillbud.Metod: Studien är kvantitativ, deskriptiv och jämförande. Förekomst av tillbud samt upplevelse av stress/trötthet besvarades på ett svarsformulär av sjuksköterska och undersköterska under eller direkt efter intrahospital transport. Totalt ingår 42 transporter.Resultat: Tillbud förekom vid 19 transporter.

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

Today, companies can take advantage of mass intelligence by making use out ofcrowdsourcing. Crowdsourcing is a business model that uses the power of the collective bythe offer of a problem by means of competitions in various social media. The benefit ofcrowdsourcing is that the company gets more creative and creative solutions to the sameproblem, which would not have been possible if the company solved the problem internally.The larger mass gains an insight into the company, which in return also releases power tothe company's development. The study aims to examine the way in which citizens can beattracted to participate in the development of public transport using crowdsourcing. The studyis based on both qualitative and quantitative approach since the study has a qualitative pilotstudy.

Sweden has a natural gas grid extending along the west coast, from Trelleborg to Stenungsund. There are also several smaller local networks where a planned natural gas pipeline from Skutskär to Hofors prompted the need for a comprehensive study. This study examines the linkages that exist in terms of technology and market of natural gas and biogas in Sweden. Sweden has set high targets for the future with ambition to become independent of coal and oil as energy sources. Since 1985, a part of the solution has been import of Danish natural gas.

Urban forests are important for people to get at break and be able to relax in a stressful world. Several studies show that we feel better through being out in the forest and historically this was the normal environment for us. As a result of population growth and urbanization we tend to spend less time in nature nowadays than before. Due to this development urban forests have become a central role in our society as a place where people can fulfill their needs and interests. The management of the urban forest is therefore important, especially for municipalities that own forest which is supposed to be of benefit to local residents.Falköpings municipality owns approximately 260 hectares of forest in the popular and most visited recreational area along Mösseberg?s southern slope.
