Examensarbetet har syftat till att kartlägga försörjning och lagerhållning av material, som ligger på lineförråd hos ABB Machines, samt utarbeta förbättringsförslag för att minska kostnaderna och samtidigt höja den interna servicenivån. Litteraturstudier har genomförts, inom bland annat lagerstyrningssystem, styrning av lågvärdesartiklar och ABC-analys. För att se hur andra företag har valt att lösa försörjningen av lågvärdesartiklar genomfördes en fallstudie hos ABB Robotics och som komplement till teorin om leverantörsstyrda lager, även kallat VMI, genomfördes en fallstudie hos Motor & Machines leverantör Arvid Nilsson Sverige. Analys av nuläget utifrån litteraturstudien visar på ett antal förbättringsmöjligheter inom områdena lager och lokaliseringen av lineförrådsmaterial, materialförsörjningsflödet samt underhåll av lager. Medellagervärdet för lineförråden är 6,7 M SEK.

Nybyggnation och underhåll av skogsbilvägar medför stora kostnader för skogsbruket. Georadar (GPR) är en teknik som kan användas för att läsa av en vägs struktur vilket ger ett möjligt tillvägagångssätt för att reducera kostnader vid upprustning av vägar. Detta genom att endast partier med sämre bärighet rustas upp och därmed läggs rätt mängd material på rätt ställe längs vägen. Alternativet är dagens subjektiva bedömning av åtgärdsbehov och godtycklig placering av grusmängd. Syftet med denna studie var att kvantifiera skillnader i spårbildning mellan 100 %, 75 % samt 50 % påförd materialmängd i överbyggnaden av total rekommenderad materialmängd för att uppnå bärighet motsvarande vägklass 3B, samt hur spårbildning i vägkroppen påverkas av vältning. Grusmängden för överbyggnaden dimensionerades med ledning från data insamlade med GPR och fallviktsmätare.

Extensive planting of the tree species lodgepole pine (Pinus contorta var. latifolia) during the 1970s and 80s has resulted in large areas now being available for commercial thinning. However, the varying quality of the stands creates a problem. The purpose of this study was to investigate, at the Torsby district of the Stora Enso forest company, how well the present computer records of the stands correspond to reality and determine which stands are, from a qualitative perspective, suited for timber production. Finding variables that indicate better stands would give Stora Enso the possibility of selecting qualitative stands which are more profitable to thin. The study included 32 stands containing at least 70 % Pinus contorta.

The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.

This work derives from the question ?What is a beautiful road??. The question is being discussed in interviews with two employees at the Swedish National Road Administration and two former members of the ?Council of environment and beauty? at the Swedish National Road Administration. The interviews are summarized in my own discussion about the concept of ?Beautiful roads?.

Syftet med uppsatsen är att beskriva hur fem svenska skogsbolag utför sin skogliga planering och analysera möjlig utvecklingar av planeringen. De företag som ingår i beskrivningen är AssiDomän, Holmen, Korsnäs, SCA och StoraEnso. Materialet som uppsatsen bygger på kommer till största delen från intervjuer som gjorts med personer med lämplig befattning på de olika företagen. Planeringen kan delas upp i tre huvuddelar; strategisk, taktisk och operativ. Organisationen på företagen stämmer väl överens med dessa steg.

The effects of Reindeer mechanical damages on the planted regeneration of Pinus sylvestris and Pinus contorta. Semi-domesticated reindeer can damage young trees. In late winter reindeer rub their antlers against young trees. The aim of this study was to quantify those damages. This study covered planted objects from three different areas in northeastern Sweden.

This thesis deal with tick burden on roe deer (Capreolus capreolus) fawns, in relation to age, weight, hind foot length, and as well as to vegetation and habitat on bed sites. Roe deer fawns (N = 25) were captured from May 27 to June 27. Samples of ticks were collected and tick burden were estimated. Of all sampled ticks the nymphs and adults were Ixodes ricinus, while the larvae were not identified. 4.4 % of the sampled ticks were larvae, 55.0 % nymphs, 26.8 % adult females, and 13.8 % adult males.

Texture is an important soil property and accurate particle size analysis of soil texture is therefore crucial. There are a number of well-established and newly developed methods available for determining soil texture. In order to compare the results of these methods, the differences between them must be determined. The difficulties, problems and differences regarding texture class determination were examined through a study performed on forest soil samples. The study compared different methods (pipette, hydrometer and field methods) and two types of dispersing agents (sodium pyrophosphate and sodium hexametaphosphate (calgon)) commonly used for particle size analysis.

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.

Today?s forest managers implement a large number of methods to increase the amount of dead wood in Swedish forests. They use everything from high cutting of trees to girdling trees and burning forests. However, implementation of these measures without proper knowledge of their consequences is a common problem. This study has been performed to increase knowledge about two of these measures, girdling and high cutting, and how these actions affect the number of wood-living insects living on dead trees.

This study was made in an attempt to give the forest research centre Mógilsá a producedtetratherm map and a better understanding of how topography and temperature influencethe growth of two tree species. The digital tetratherm map model, covering the northernpart of Iceland, was developed to investigate the correlation between tetratherm and thegrowth of Picea sitchensis and Larix (sukaczewii + sibirica). The study confirms theusefulness of digital terrain models in providing data for a lot of different factors and forthe tetratherm model. Hopefully will this tetratherm map be used in future studies.Secondly, investigations were made correlating the growth of the two species againsttopographic factors representing height above sea level, distance to the sea, slope andtopex. Thirdly, investigations were made comparing the aspect and the ground shape tothe growth.The growth rate of Larix had strong significant correlations to the tetratherm and thedistance to the sea- factors.

The aim with this thesis was to investigate what characterises an English Arts and Crafts garden how they could be modernised in Sweden. My research was limited to 20 weeks of full-time writing and worth 30 ECTS. Through literature studies, interviews and site visits I could analyse my findings which resulted in a concrete garden design project. The Arts and Crafts was a movement that started in England during the 1880?s and evolved as a reaction towards the industrialisation. The influence came from the writings and practices of John Ruskin (1819-1900) and William Morris (1834-1896) who advocated the importance of craftsmanship. The Arts and Crafts movement also became a ?recipe for life? and was associated with a healthy and morally pure way of living.

Emerging infectious diseases are a recurring threat to both human and animal health. Understanding the multiple causes behind the emergence of new diseases is key to the prevention of new and potentially devastating outbreaks. The list of underlying causes is long, including a variety of anthropogenic, environmental, molecular and climatic changes that promote the emergence and spread of disease. Two of these factors are central to the emergence of new diseases and receive special attention in this study. The spread of disease from wildlife to livestock and diseases that spread from animals to humans (zoonoses) are of importance as they implicated in the majority of EID events.

Ammerån which is a small forest river in eastern Jämtland is a well-known river that has been a popular fishing river for a long time. The actual Ammerån begins downstream the lake Solbergsvattnet at Hammerdal and flows into the Indalsälven 10 km upstream Hammarstrand. The river environment switches between forests with wilderness feeling and open agricultural land. The entire Ammerån is today a nature reserve and protected from hydropower development. Fishing in Ammerån has mainly been focused on trout and grayling, and is so even today.
