Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi

The incineration of waste is steadily increasing in Sweden and so is the production of ashes. The bottom ash has for many years been used as construction material in landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it can replace natural gravel in parts of roads and surface constructions. Today this use is only approved within landfill areas where leachate is collected and checked.

Gränser i Grödinge : Om hägnadsanläggningars funktion med utgångspunkt i en fosfatanalys av RAÄ 78 samt RAÄ 79 i Grödinge sn på Södertörn

This paper deals with the question of when hill forts ? or enclosed mountains ? were built and to what purpose, by examining two enclosed mountains (RAÄ 78 and 79) in Grödinge parish in the province of Södermanland. A phosphate analysis was conducted to trace anthropogenic activities. The analysis showed only a slight elevation of phosphate content in the soil. A histogram indicated that the elevations were not normally distributed, which could suggest that they were caused by anthropogenic activities.

Däck-mark Interaktion hos skogsmaskiner

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

Förändrad aptering av massaved från 3- till 4-meterslängder vid gallring inom Södra : en systemanalys av effekter från avverkning till levererad virkesråvara

The costs of logging and of transportation with truck are dominating the total cost of wood delivered at industry. To support the profitability for the members' forestry the processing and handling with the timber has to be as efficient as possible. Increased length of pulpwood in thinning is one conduct that can result in higher productivity and/or lower costs. The study is scaled as a system analysis with the aim to exemplify the differences between working with 3- and 4-meter as standard length of pulpwood, related to biological aspects, timber receipts, cost of logging and cost of transportation with truck. Important aspects are if the change is technically and biologically feasible and economically profitable.

?Vi försöker servera ett smörgåsbord? En studie om att attrahera utländska direktinvesteringar till Göteborgsregionen

Globalization allows companies to expand and establish themselves in other markets, which can have unexpected consequences for those who are not aware of the controversy or sacrifices that are required, and Gothenburg, Sweden is not an exception. The study has focused on two institutional theories that can explain whathappens when a foreign direct investment takes place, Institutional work and Institutional duality. The study was conducted at Business Region Gothenburg and the interviews took place at department of establishment and investment. The result shows that to overcome institutional barriers they use networking, relations, and marketing of the region of Gothenburg as examples. The paper also argues that by performing some sort of institutional work, institutional duality occurs..

Utveckling av Mätmetoder för Färdmotstånd

The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.

Kvinnlig chef i byggbranchen : faktorer som utgör hinder till avancemang

Background: Studies that have been made in male-dominated organisations shows that only few women have succeeded in advancing to the higher positions in all businesses. Statistics shows that merely 4 % of the managers in all building companies are female. The manager role has earlier always been classified as most suitable for men resulting in barriers for women who strive for management positions. This problem is now very renowned and is called the glass ceiling. To improve the current situation, both the organization's structure and culture, have to be modernized for more women to succeed and get the courage to get into the industry.

Från militärområde till stadspuls : Stadsdel Norr - en (nästan) vit fläck på Östersunds stadskarta

How can former military area I5 in Östersund, Sweden, evolve into Stadsdel Norr ("The Northern Quarter") ? an attractive part of the town center? In a theoretical part of the essay the significants of well functioning towns and streets are investigated. The history of Östersund and I5 is shortly reviewed. Present recommendations concerning city design are presented along with guidelines from Vägverket (National Road Administration) for urban streets. The conclusion reached is that a fundamental structure of streets and roads, public and private spaces, is crucial for the possible future development of an area.

Utvärdering av trafiksimuleringsmodellen RuTSim

Trafiksimulering är ett användbart verktyg då olika typer av vägar ska studeras. Statens väg och transportforskningsinstitut, VTI, har under de senaste åren utvecklat en ny landsvägssimuleringsmodell, Rural Road Traffic Simulator (RuTSim) (Tapani 2005). För att en simuleringsmodell ska vara användbar måste den ge en god överrensstämmelse mot verkligheten. Syftet med detta examensarbete är därför att utvärdera RuTSim, genom att kalibrera och validera två 2+1-vägar och en vanlig landsväg med mötande trafik. Detta både för en implementerad frifordonsmodell samt befintlig modell med trafikinteraktioner.

På väg mot en fri översättning ? eller bara på drift?

Denna uppsats analyserar ?det fria? i en översättning ? alltså de kriterier som utmärker en fri översättning. Dessutom analyseras texttrogenheten utifrån ekvivalensbegreppet.I detta syfte ligger tyngdpunkten på en analys av semantiska tillägg ochutelämningar i måltexten. Dessutom studeras översättning av engelska namn, talspråk, svordomar och metaforer, samt ändring av syntaxen i måltexten. Materialetbestår av de två svenska översättningarna av Jack Kerouacs roman On the road, nämligen På drift från 1959 och På väg från 2008, som jämförs med originaltextenoch med varandra.

Ola Rapace verkar ju lycklig, men hur gör då jag för att också bli det?

This paper examines which media messages related to happiness that can be found in interviews with famous people in the four largest lifestyle magazines in Sweden for the age group 16-34. The magazines are Cosmopolitan, Elle, Café and King. Depending on which magazine the reader chooses to read he/she will be presented with different roads to happiness. Common for all examined magazines are happiness factors related to personal goals, determination and work. Often in a causal connection where the goal orientation and determination is tied together with success in work and career for the interview persons.

Långsiktigt spårväxelunderhåll - Förutsättningar och möjligheter

Due to their complexity and heavy wear from rail traffic, switches are a sensitive part of the railway infrastructure and moreover expensive to maintain. Furthermore, increasing railway traffic not only accelerates the wear rate but also obstructs the necessary maintenance measures. This paper examines the opportunities for a transition to a long-term maintenance strategy in the Swedish railway network. It contains a study of the maintenance strategy of Banverket, and also analyses statistics of errors in the railway infrastructure. The survey was completed utilising interviews with infrastructure managers, maintenance contractors, planners of railway operations and the Banverket material service department.
