The Göta älv-bridge is a welded steelbridge which is located in Gothenburg,it connects the inner city of Gothenburgwith the island Hisingen. Cracks wasdiscovered in the steel in 1999-2000which started an investigation of thebridge to clearify the condition of thebridge. The conclusion was a monitoringsystem based on laser light sent throughan optical fiber.This report describes the bridge, thedamages, the monitoring system and thetraffic on the bridge.Stefan Pup, at Vectura Borlänge was mysupervisor during this work. In myinvestigation the costs of themonitoring system and the costs ofclosing the bridge is compared andevaluated. The biggest investigatingpart is the costs of closing the bridge.The results of my investigations is thatclosing the Göta älv-bridge would cost 1107 300 SEK / day.

Data retrieved from airborne laser scanning represents a new source of forest data. Today, the technology has matured so that it can function in an operational environment. The aim of this study was to compile areas of application of laserdata in forestry. Moreover to analyze costs and accessibility of laserdata. The goal was to provide private forest owners information to support assessments of possible benefits of laserdata.

The purpose of this study is to investigate if there is enough consideration taken to sensitive forest areas close to water or wetlands during clear cutting assignments, and to estimate the extent of damage made by forestry machines used at that time. A field and literature study is used to show how to improve and prevent the damage made in the wake of the machines. This study is made for Sydved, and shall culminate in a policy to prevent ground damage during their clear cutting assignments. The areas which were part of the field studies were clearcuttings on fine grained soil close to water and wetlands. The purpose was to find out if the water had been affected, what had been done to prevent ground damages and what more could have been done. The results of the field studies show that more work needs to be done to reach up to expectations. More information about the assignment area, better planning of sensitive regions, and strengthening of the main haul roads with brush are some of the improvements that can be done. There is also a need for more exact guidelines, follow-ups and education for everyone involved to have the same goals and understanding to prevent ground damage..

Ökad användning av byggtekniken massivträ kan ge ett positivt bidrag till hållbart byggande. Utvecklingen inom datornavigerad bearbetning ger massivträ möjligheten att rationalisera byggproduktionen inom trä. Tekniken ligger rätt i tiden och kommer att värderas allt högre då den tillvaratar materialets karaktäristiska egenskaper.Utvecklingen av massivträ har resulterat i teknikvarianter av hur virke kan sammanfogas till solida element. Ett behov har funnits av en marknadsjämförelse mellan befintliga principer där studien förtydligar grundläggande skillnader för intresserade byggaktörer. Problemfrågan för denna studie har varit: vilka principer för sammanfogning av trä till plattelement inom massivträ är mest fördelaktiga? Detta sett utifrån faktorerna produktionskostnad, hållfasthet och ekologiska övervägningar.För att förtydliga den undersökta byggmetodens nytta i ett vidare perspektiv har det presenterats en allmän beskrivning av massivträ.

During the late 1800s fire suppression became increasingly effective in northern Sweden which led to decreased areas of fire-disturbed woodland and successive changes in the structure of forests. In the long run this can pose a serious threat to fire-dependent and fire-favored species. Today some fire-prone forest reserves are burned as a nature conservation act. Often partial cuttings are made before burning, with somewhat different motives. The purpose of the study in Långsidberget nature reserve was to give a general picture of forest history and its affect on today?s forest condition, and to show how partial cuttings affect burning conditions and results. Långsidberget is located close to areas that were colonized during the Middle Ages.

Holmen Skog AB is an important supplier of conifer pulpwood to the Iggesund Paperboard mill. After logging and transport to the landing by a forwarder, the wood is loaded on trucks for further transport, often by using separate loaders. During this handling process considerable amounts of stone material is sometimes mixed into the pulpwood and this causes problems for the industry. The aim of this study is to identify which part of the chain from forest to pulpmill, that contributes the most to this contamination. Sizes and total volumes of the contaminating stones were also investigated.

The purpose of this report is to study the risk of dust explosions at the candy manufacturing plant Leaf Sverige in Gävle, Sweden. The risk analysis was conducted with a preliminary hazard analysis, PHA and event trees. The analysis focuses only on the risk posed to employees and material damages at the plant. No third person injuries have been considered. Another purpose of this report is to study risk awareness and risk communication concerning dust explosions.

The need of raw material does of course fluctuate but the long term view is an increasing demand due to the growing consumption of sawn timber products, pulp, paper and lately also biomass. This has led to a keener competition for wood. At the same time there is an ongoing structural change of a significant part in the Swedish wood supply market, the private forest owners. In 1992, 22 % of Sweden´s 335 000 private forest owner lived apart from their forest. In 2007 this figure had risen to 36 %.

The Scanian woodfences has been determined by two mainly elements: Scania's composition of tree species, with a large element of deciduous forest, and the local building tradition which has more in common with the European continent than the Swedish tradition. By examining responses from ethnological question lists deriving from the first half of the 1900s, combined with literature studies, I have been able to deepen and broaden the knowledge behind the various fencing design. In addition I ?ve constructed maps which could illustrate their historical geographic distribution.I have come to the conclusion that there was three main types of woodfences that was most common until the barbed wire was introduced in the early 1900s and later on replaced the elderly woodfences. Common for the three main types is that the base material was made out of Juniperus communis, this largely because of its durability against rot.

The aim of this thesis is to identify some of the obstacles to trade, that occurs on the common market, and to analyse the errors that still occurs in the national authorities application of the principle of mutual recognition. Is the principle of mutual recognition sufficient for the creation of a common market, or is there a need for additional measures to cope with the obstacles to trade that still exists on the common market? The problems related to the incorrect procedures of the national authorities and the fact that undertakings prefer to bring their products in to line with the rules of every single member state must be solved, if the principle of mutual recognition is to become trustworthy. On some areas, harmonisation ought to be chosen above the principle of mutual recognition, but in other cases an increased administrative collaboration, mandatory training for the national authorities or information campaigns intended mainly for undertakings could be the answer. The possibility to help undertakings to sue member states for damages should also be investigated.

The Latvian building company Laval un Partneri Ltd (Laval) posted Latvian construction workers at the rebuilding of a school in Vaxholm in autumn 2004. Because the company refused to sign a collective agreement with Svenska Byggnadsarbetareförbundet (Byggnads), which is the Swedish trade union for constructions workers, Byggnads put the construction site under a boycott. Next Laval sued Byggnads for damages in the Swedish Labour Court (AD) because Laval considers the boycott as well as Byggnad´s demand that Laval signs a collective agreement incompatible with EC Law. AD has now demanded a preliminary ruling from the European Court of Justice (ECJ). While waiting for the preliminary ruling from the ECJ, several important questions of principle stand unanswered.

Reporting harvested and forwarded volumes are important for the forest industry as it provides information of the size of the stock and facilitates logistics. Figures from Holmen Skog show low reporting frequency. The purpose of this study is to investigate the reason and find suggestions for improvement. A total of 17 machine operators were interviewed using a questionnaire combined with open questions. The results show that the majority of the machine operators find it simple to use the reporting system, although, some of them reports that it doesn?t always work as supposed to.

Background: An effective management of the healthcare's organization on one disaster site is considered as a condition in order to decrease damages and suffering at them as been hit of an accident. In KAMEDO-reports is described true accidents, how among other thing organizational parts been implemented and evaluations of which importance different decisions had. Aim: The aim of the study was to examine KAMEDO-reports concerning prehospital medical management on disaster sites. Method: Eight KAMEDO-reports was examined with focus on organization and management. Results: Four areas in which all could be influenced by the healthcare personnel in leading position was described: Management and Co-operation, Load and Go - Stay and Play, Priority and Triage.

Problem: How do delivery logistics work in practice at the building site? Where are the big problems? How to make building logistics more effective? Do the site management and the haulers agree about questions concerning both parties? What is possible to gain by using better logistics? Is it possible to gain time with better logistics and by that reducing the costs? Purpose and aim: The purpose is to discover if there are any disagreements between the site management and the haulers. If disagreements occur they will be examined and probable measures based on the problems will be suggested. Another intention is to bring key ratios concerning time spent for deliveries forward. One aim is to update a similar report made in 1972.

Projektets mål har varit att finna orsaker till delaminering av lamellimmade komponenter vid Stora Enso komponentfabrik i Ljusne. Detta resulterade i en analys av de faktorer, både material- och tillverkningsmässiga, som kunde bidra till en försämrad limfogskvalité. Analysen baserades på standard SS-EN 13307 ?Timber blanks and semi-finished profiles for non-structural uses?. En av de gällande faktorerna som analyserades var presstrycket vid limning.
