Förslag till modell av kemikaliespridning i mark anpassad för användning vid räddningsinsats - Kemspill Mark 4.0

After emergencies involving chemical spills it is of great importance that correct measures are taken with short notice, both for the security of people and in order to minimize future environmental consequences. The RIB-unit at the Swedish Rescue Services Agency initiated this study, the aim of which is to propose changes to the existing chemical transport calculation tool: Chemical Spill 3.4, included in RIB - Integrated Decision Support for Civil Protection, so that it can be used for decision support as well as in preventive work. A rough estimation of chemical transport in the subsurface is considered being of great importance when making decisions during emergency response operations.The proposition presented in this report is a non site specific chemical transport model which is designed to give a rough estimation of NAPL flow in homogenous isotropic soil shortly after an instantaneous release. The model can be used at two levels; both in situations without access to information on subsurface properties, and with more accuracy in situations with knowledge of the included parameters. For that reason the user can choose among predefined alternatives or assign the parameters a numeric value to increase the quality of the model output.

Produktivitet och kostnader vid skörd och transport av skogsbränsle från klena gallringar

Syftet med denna studie var att undersöka ett maskinsystem för uttag av trädbränsle i klena gallringar i norra Västmanland och södra Dalarna för Mellanskog. Genom driftuppföljningsdata kunde produktiviteten och kostnaderna för maskinsystemet beräknas, samt kostnaderna för sönderdelning och transport och hur dessa förändras med transportavståndet till industri. Resultatet visar att skördarens produktivitet är beroende av storleken på skördad medelstam, samt att skotarens produktivitet sänks med ett ökat skotningsavstånd. Den totala kostnaden för drivningsarbetet för ett medelobjekt (sett till maskinsystemets produktivitet) i denna studie var 178 kr/m3f inklusive kostnader för flytt, planering och tillägg för vinst. Om man bortser från dessa kostnader uppgår kostnaden för skördaren till ca 88kr/m3f och kostnaderna för skotaren till ca 61kr/m3f. Att enbart sönderdela materialet kostar 58 kr/m3s och kostnaden för transport beror på tranportavståndet, ett längre avstånd innebär en högre kostnad.

Varför miljöredovisning? : en undersökning av lastbilstransportbolag

Today?s political debate on environmental issues and environmental thinking, alongside the Swedish presidency of the EU and Climate Conferences shows that the environment is an important topic. Environment is important, not only in politics, but also for companies and the demand of environmental strategies and environmental reports has increased. This leads to an increased pressure on firms to begin to report on environmental concerns and to create active systems for environmental thinking.The aim of the present study is to examine why firms in the transport sector, mainly lorry transports, reports environmental aspects and what drives these companies to create these reports.Based on stakeholder and institutional theory we aim to examine to which extent stakeholders affects the environmental accounting and reporting. We also aim to explain how the organization is influenced to incorporate external and societal environmental procedures.

Hur långt bär cykeln? : Gång och cykling i Västerbottens län - en studie av pågående arbete med regional gång- och cykelplanering

The craft of planners are planning for a better future.

Stubbtransporter och bränslekvalitet hos stubbved :

Stump wood is a hot alternative when the heating plants demands more and more forest fuel. The aim with the study has bean to calculate the costs in four different systems for transportations of stump wood, examine if there are any differences in fuel quality for the stump wood in the different systems, analyse if the fuel quality in stump wood is affected with the time it lays by the road side and how much space the stump wood demands on the road side. To calculate the costs for the different systems a system analysis was carried out, where some of the costs were collected through field studies on Holmen Skog stump experiment and other costs were collected from literature and contacts. Data for the fuel quality study was collected from Eons heat plant in Norrköping. Data for the study of how much space stump wood takes along a roadside was collected from field studies.

Produktutveckling av kylväska för transport av vacciner i svåråtkomliga platser

Examensarbetet har genomförts i samarbete med konsultföretaget i3tex AB i Göteborg samt med Aircontainer Package System Sweden AB (APS) i Stockholm. APS utvecklar och säljer standardiserade och kundanpassade förpackningslösningar för att transportera temperaturkänsliga produkter. Ett av APS önskemål är att i framtiden kunna erbjuda fler alternativ av kylväskor. Ett av dem är en kylväska som skulle kunna användas vid transport av vacciner i svåra miljöer eftersom det idag inte finns med i deras utbud. Examensarbetet fokuseras därför på att ta APS befintliga blodväska som referens och att ta fram ett nytt koncept för transport av vacciner, samt utveckla ergonomiska egenskaper för att underlätta och optimera användningen för de som jobbar i fält på organisationer som t.ex.

Skogs- och energibolagens attityd till förnybara drivmedel vid upphandling av transporttjänster i norra Sverige

Sweden's government is dedicated to the goal of having a vehicle fleet that is independent of fossil fuels by 2030. Achieving these goals requires, among other things, new types of fuel that give lower net emissions of carbon dioxide. The present market includes stations offering lowlevel blends of renewable fuels in conventional diesel as well as some stations offering renewable fuels only. The purpose of this study is to survey purchasers? attitudes to the use renewable fuels in roundwood and bioenergy transport in forest- and energy companies. The study was based on qualitative interviews through a combination of face-to-face meetings and telephone interviews with each sample group. The total number of respondents was ten (10), consisting of five (5) from forest companies and five (5) from energy companies. Transport service purchasers were generally positive to renewable fuels and considered these necessary in the future.

Handlingsplan för rening av dagvatten från hårt trafikerade gator i Örebro

The main purpose with the project has been to approximate the magnitude of the pollution transport from the actual road surfaces and to get an approximation of the possibility to collect the pollutants to reduce the load to the water and improve the water quality.The quantity of pollution transport from the most trafficated roads areas in Örebro city has been calculated. Roads whith a traffic exceeding 10 000 vehicle/day. The study has been done with the calculation tool StormTac. Through analysis of traffic loads and road surface, which together with a different kinds of parameters gives an approximation of the pollutant transport.The calculation has included some metals and other substances in the stormwater and has also included the present of suspended solids.

Ute och cyklar? : på jakt efter en metod att mäta upplevelse

Well-functioning bicycle paths are relevant issues in today´s society as a way to increase active transport. Active transport means working for a better global climate, urban environment and public health. What we experience on a bicycle affects the choice of a bicycle path and is a subject where there is much left to explore. This essay examines methods in environmental psychology literature that measure the experiences of landscape. The aim is to find and apply methods to measure the experience of two bicycle paths in the Skåne plains.

Realistisk restidsberäkning för comodal reseplanering

With increasing traffic congestion problems in bigger cities, it is becoming more and more important to provide the traveller with correct information about all transport alternatives. When doing that, the traveller gets the opportunity to make the best decision based on the current traffic situation. Instead of traditional travel planners, where public and private transport modes are presented separately, the co-modal travel planner offers a combination. In order to make the comparison correct and fair, the travel times have to be estimated realistically and on equal basis. This master thesis focuses on how to estimate travel times in the city of Stockholm for journeys by cars, public transport, bicycles and also for walking.An investigation of the available data on maps and travel times shows where the currently used methods are lacking.

KOLLEKTIVTRAFIKENS GEOGRAFISKA VARIATIONER I TID OCH KOSTNAD ? HUR PÅVERKAR DETTA BOSTADSPRISERNA? : Fallstudie Uppsala län med pendlingsomland

The distance between home and work has increased in recent decades. By the development of infrastructure and public transport, jobs farther from home have become more accessible and this development has in turn increased commuting. Commuting travellers often pass over administrative boundaries which often serve as borders for public transport pricing. Also the market control prices. Research shows that travel times and costs significantly affect commuting choice.

Vad väljer du? En undersökning av beteendepåverkande åtgärder för att skapa hållbara transportsystem

Människors transportvanor skapar idag tillsammans med andra faktorer ohållbara transportsystem. Jordens befolkning använder färdmedel som förbrukar icke förnybar energi i allt större utsträckning, vilket skapar transportsystem som inte är hållbara. Dessa faktorer medför en stor miljöpåverkan på vår jord och om vi fortsätter på samma sätt som de senaste 60 åren belastas jordens kretslopp allt mer, för att slutligen upphöra att fungera.Infrastrukturen idag motsvarar de behov och krav människor har på sin transportmiljö och dessa vanor bygger till stor del på vår historiska tradition av transport. Denna historiska tradition motsvarar inte ett långsiktigt tänkande. De beteenden och levnadsvanor vi har idag påverkar kommande generationers livsmiljö, vilken kommer att äventyras om vi fortsätter på samma sätt.
