Ekonomisk värdering av användandet av underbett på timmerbilar
Holmen Skog has in some places in their operation area access to timber trucks with centre mounted scrapers. They make transportation more flexible and reduce reliance on contractors for road maintenance. The trucks with centre mounted scrapers have a higher tare weight, making them less productive and therefore they receive compensation with a 0.75 % increase on transportation price.
The purpose of this study was to investigate what actions a timber truck with centre mounted scraper can perform with acceptable quality in winter, and to examine if it is an economically profitable solution for the truck operator and charterer.
The study was done in three stages; interviews, performance analysis of the transportations carried out and an economic analysis with the help of Sven Erik Gilles spreadsheet tool. The study included the districts Delsbo and Hudiksvall.
Transport av hästar i Sverige - en enkätstudie
Under de senaste tio åren har antalet hästsportsevenemang ökat drastiskt, både internationellt och i Sverige. Det ökade antalet hästsportsevenemang visar på ett ökat intresse för hästsport och hästar vilket i sin tur föranlett en ökning i transport av häst. Vetenskaplig litteratur inom ämnet är knapp och det som finns berör vanligen fysiologiska mätningar för att uppmäta stress under transport. För att få en uppfattning om hur marktransporter av häst går till i Sverige och skapa en kunskapsbas för framtida studier utfördes en webbaserad enkätstudie. Enkäten låg ute i 6 dagar och 1013 personer svarade varav 906 stycken kunde analyseras.
Från trafiklärare till transportlärare
Abstract (in English)The purpose of this work is to find out what the driving instructor who currently works as a transport teachers feel about today´s driving education to transport high school to how it works at driving school. I describe in the study on how to become a transport teachers and on their everyday work. Even what others have written on this topic on driver training. I also interviewed four driving instructor who currently works as a transport teacher, about what they had for opinions on this issue. The method I have used myself of where unstructured questions to get so descriptive answers to questions as possible.
Levbart transportsystem i Uppsala
In this thesis a transport system is sought after thatif realised in the city of Uppsala could provide bothwell-being to all its inhabitants and sustainability,here jointly refered to as liveability. It is found thatthe car dominated transport system that is inoperation today provides two fundamental values,namely accessibility in both time and space, whichsets it apart from other transport solutions. Thesetwo values are of immense importance for theliveability in our modern world. On the other handthe car dominated system decreases the liveabilityof Uppsala in several different ways. Some of theseproblems, it is argued, could be solved within thecar system, through the adoption of moreenvironmentally friendly cars etc., but otherproblems are inherent in the car system and willremain no matter what changes are made.
Strategisk och taktisk planering samt länken där emellan : analys av planeringsprocessens genomförande vid SCA Skog
To effectively manage a forest resource for both economic and other values good planning is required. The problem is complex since you want to know which forest to cut and when. Often a hierarchical planning structure is applied, including strategic (long-term), tactical, (medium-term) and operational level.
Today SCA Forest is one of few forestry companies in the northern Sweden with an integrated forest wood supply and industry. The goals of the company are to supply their own industries with wood and to manage the resources of the forest through a long-term perspective with satisfactory profitability.
P?m?rkning vid virkesberedning - Bastning. Ett hantverksf?rs?k
This essay aims to investigate a rare method of marking up timber before hewing it. The
method for marking up timber is by eyesight, where visual judgment and the use of a broad
axe are the tools employed. The broad axe is driven through the bark and exposes the inner
bark in a straight line. The method is described by a craftsperson dating back to the 1930s.
There is a lack of information regarding the method.
Enkätundersökning hos skogsägare inom SCA Skog Norrbottens Förvaltningsområde
This report has been done in collaboration with SCA Skog, Norrbottens Forest Management Area. The purpose of the survey is to try to find out what the forest owners who either live in Norrbottens Forest Management area or outside but has their forest holdings in the administrative area has the vision of SCA Forest and their forest services offered by the administration. But also to find out the presences of other timber buying players who procures timber in the administrative area. This study seeks to determine if there are deficiencies that may need changes or improvements to the prevailing conditions in Norrbottens management area.
The literature study is about how to design a questionnaire based on what you want to know and what to consider in order to eliminate the problem of constructing a questionnaire.
A questionnaire was sent to 400 randomly selected forest owners who have their forest holdings within SCA Forest Norrbotten Management Area. And of the 400, it was 181 respondents with 39 women and 138 men.
Kvantifiering och kartering av föroreningstransport inom ett avrinningsområde
The aim with my master thesis is to develop and test the applicability of methods to quantify and map solute advective travel times and pollutant transport at the catchment scale. Such quantification and mapping can increase the understanding of catchment-scale pollutant transport in general and contribute to the identification of the main sources of water pollution and the most efficient measures to reduce such pollution. The study area is the catchment of Oxundaån, about 20 km north of Stockholm. For detailed GIS modeling of water flow and catchment-scale contaminant transport in water, I´ve used new high-resolution elevation maps, land cover maps and soil maps combined with other available relevant data..
Effekt av biotopvård på öringpopulationen i två vattendrag
I have done a follow up study of the restoration of two rivers, Röälven and Grundan, in order to evaluate the effects of the restoration on the endemic population of trout. Both rivers have been used for timber floating during many years throughout the 20th century, and because of this, had all obstacles such as rocks and wood parts removed. In 2004-2005 both rivers were restored, and rocks and wood were put back into the rivers. Spawning grounds were created and boulder dams were constructed to promote the streaming water. The result showed that the trout population of both rivers increased after the restoration, but also that the trout population of Röälven increased more than that of Grundan.
Tidsstudie av containerhuggbil
The fork lifter chipper truck is a concept which has been developed for harvest and transport of bio fuel. The system consists of one fork lifter chipper truck and 1, 2 or 3 transport lorries, usually two, which serves the fork lifter chipper truck. The system is driven by the fork lifter chipper truck that produces chipped material into a container on the truck. When the container has been filled the truck drives to the landing site where it?s offloaded.
Elektroniska konossement i Sverige. Elektroniska registreringar och reglerna för konossement.
While this summary is written in English, the paper published is written in Swedish.The paper concerns itself with the legal status of electronic transport records in a Swedish context. The main question asked is whether rules for bills of lading should be applied to electronic transport records, or if they should be treated according to general rules. A secondary question is asked; partially to help put the main question into context and partially to see whether the different legal regimes will lead to different solutions to an issue. This second question is if electronic transport records can effect the transfer of property (sv. sakrätt).
Hur ansvariga vid vägarbeten ser på sin uppgift kopplat till säkerhet och framkomlighet
In 1997, the Swedish parliament adopted a decision on Vision Zero (nollvision) in the road and transport system. Vision Zero means that no one should be killed or seriously injured in traffic accidents in the road transport system (Prop. 2003/04: 160). For the Transport Administration in Sweden (Trafikverket), this means increased demands on security and signage at road work sites around the country. This in turn means increased demands on the contractors that carry out road work for the Transport Administration.
Temperature monitoring during transport of test samples
Quality is the main focus in management of all laboratories. Accurate results of the analyses are not only determined by the analytical procedure but also by preanalytical factors. In the total analytical process of clinical specimens, there are many possible preanalytical sources of error. Monetoring of temperature on test samples of the transport boxes is one way to reduce the mistakes in the preanalytical phase.In this study, four laboratories from primary health care were invited to participate. The temperature has been measured on test samples of the transport boxes being delivered to the laboratory.In three cases the temperature remained within the limits, but in the fourth case the temperature varied more than the allowed interval.
Analys av framtida potential för virkesköp från privata skogsägare i Västerbottens län : beslutsunderlag för virkesköpsstrategier
This study was conducted on behalf of SCA forest AB, Västerbottens forest administration. Timber procurement from non-industrial private forest owners has become an increasingly important part of SCA:s wood supply. The objectives of this study was to report the current forest conditions in the private forests in the county of Västerbotten, analyse the potential for procurement of wood from private forest owners, and provide a basis for decisions on future strategies for timber procurement from private owners.Material and data have been collected from different sources, mainly from Swedish National Forest Inventory and SKA-VB08. This material was the basis for the analysis and calculations performed with the Heureka application PlanWise. This study area was divided into six different analytical areas (Coastal south, Coastal middle, Lycksele, Inland south, Inland north, Skellefteå), where each area of analysis is represented by a number of municipalities.In this study, two scenarios were specified; one describing the current forest management with current harvesting levels and the effects of these assumptions, the second to illuminate what potential there is for future timber harvesting.
Kollektivtrafikens idé : ägandeförändringar i Stockholms samtrafikhistoria
This thesis is about the idea of public transport and the discussions stirred in the media during changes in ownership. More specifically it is a study of the historical situation of Stockholm, Sweden, where the periods chosen are the 1910s, 1960s and 1990s.During the 1910s Stockholm?s first and largest tram company was taken over by thecity, and a period of public ownership began, which in the 1960s changed form whenthe county council took over the city?s principal authority and formed the politicallyadministered company SL (Storstockholms Lokaltrafik, Greater Stockholm LocalTransit Company). Between these periods the word kollektivtrafik (public transport)was established in the Swedish language. This study describes and compares the ideasconcerning the phenomenon of public transport.The aim of the study is to analyse the ideas, values and ideals concerning public transport in the media, defined as newspapers.
