Slutväxel HFT : Konstruktionskoncept för banddriven skotare

Sveriges samlade skogsindustriföretag förutspår en förlust av marknadsandelar, eftersom man inte lyckas hålla samma tempo på produktionen som många andra länder. En orsak till detta är att skogsmaskinerna är för långsamma. Skotarna, vars uppgift är att förflytta virket från avverkningsplatsen till en uppsamlingsplats, bär en stor del av skulden. De hinner inte transportera virket tillräckligt snabbt. För att råda bot på detta ska en ny typ av skotare utvecklas, vars plattform inspireras av försvarsteknologi.

Bildskapande : En undersökning i hur pedagogerna på en förskoleavdelning ser på och bemöter barns bildskapande

This report describes a study of how educationalists, from one preschool group, approach to and respond to children ?s creative activity in preschool. To answer the survey ?s purpose I used four research questions, which is the following:-What function do the educationalists give the creative activity in the working?-How do they see the importance of thecreative activity for thechild and its development?-How doeducationalists considerthat theyrespond to the child's creative activity?-Is thereany norms surrounding creative activity in preschool?The theoretical base of the study is rooted in the sociocultural perspective, where creative activity and visual arts can be seen as mediating cultural tools. The method is a qualitative interview of five preschooleducationalists.

Hyggesbränning på Orsa besparingsskog - en studie på tillväxt och föryngring,15år efter etablering

The main purpose with this study was to investigate whether the tree growth differs or not in prescribed burnt areas compared to mechanically scarified. Together with the result from the main purpose, answers of whether it's possible or not to combine nature conservation with tree production in prescribed burnt areas was presented. In these areas the regeneration were analyzed to see if there was enough tree plants to comply with the Swedish Forestry Act regulations terms for approved regeneration. A field survey was conducted at 6 objects, three objects for prescribed burning and three for mechanically scarification. All objects were planted within the same year.

Biogasprocessen : Bestämning av verkningsgrad

Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.

Lean Produktion på mjölkföretag - fungerar det?

The contact company, LRF Konsult, is a consulting firm specialized in areas of law, real estate, finance and taxation. Discussions on the subject of agricultural improvement in the area of Lean, has primarily been driven by the Royal Swedish Academy of Agriculture and Forestry, where LRF Konsult also participated. This thesis can be seen as a preliminary study of how Lean can work within agricultural enterprises.The thesis primarily focuses on the possibilities dairy farms have to improve operations. What practical benefits they can obtain through the implementation of Lean. And how an implementation could take place.By visits to two dairy companies, and through interviewing their respective business leaders, an image of the companies activity for improvement, in connection to this thesis was established.

Granföryngring på tallmark, hur ofta förekommer det? :

This survey was made during the summer of 2004 and the spring of 2005, on commission from the National Board of Forestry. The aim of this report was to investigate how often Norway spruce (Picea abies L. Karst), is planted on poor Scotch pine (Pinus Silvestries) sites and if it affects the yield of Norway spruce? In order to investigate this, data from 29 stands witch had a lower site index than T24 was collected. The investigated stands were situated in the southern-eastern Sweden. In 20 plots in each stand, the highest tree, age, number of seedlings, site index and tree species per stand were measured.

Integration mellan skog & förädlingsindustri : en intervjuundersökning

The aim of this master thesis is to study the integration in Sweden between forestry and bulky industries as fiber- and sawmilling companies. The analysis is based on theories about transaction cost economies and competitive strategy. The studied companies are active on the Swedish roundwood market. The buying actors on this market were divided into two groups; fiber- and sawmill industries. Three companies from each group were chosen subjectively by the author.

Självkännedom - En kvantitativ studie om niondeklassares synpunkter om att arbeta med självkännedom inför gymnasievalet

Syftet med undersökningen är att ta reda på om niondeklassare anser att det är relevant att arbeta med sin självkännedom inför gymnasievalet samt om eleverna är medvetna om att den möjligheten finns hos en studie- och yrkesvägledare. Frågeställningarna som besvaras i denna undersökning är: Hur värdefullt anser eleverna att det är att arbeta med självkänne-dom inför deras gymnasieval? Hur medvetna är eleverna om deras möjlighet till att arbeta med sin självkännedom med hjälp av en studie- och yrkesvägledare? Vilka vägledningsme-toder anser eleverna är mer eller mindre relevanta för att öka sin självkännedom? Det finns studier som visar på att information tar större plats i ett vägledningssamtal än vad självkännedomsarbete gör. Som blivande studie- och yrkesvägledare har vi i utbildning ta-git del av olika karriärteorier och vägledningsmetoder som ska främja den sökandes själv-kännedom. I läroplanen, Lgr 11, nämns inte självkännedomsarbete som en del i vägled-ningen vilket det gjorde i läroplanen från 1980. En kvantitativ studie i form av enkäter har använts för att undersöka detta.

En Djupdykning i Kommunikationsstrategi : om konsten att locka folk till svenska dykvatten

Purpose/Aim: To create a communication strategy for PADI Nordic with the intention of getting Swedish divers, who have been certified abroad, to Swedish dive centers.Material/Method: The study is based on a number of personal interviews conducted with a) divers who are active in Sweden, b) divers who are not active in Sweden and c) representatives from PADI and PADI affiliated dive centers.Main results: The main reason that people who have been certified abroad do not dive in Sweden is that they regard it as being too complicated, too cold, too expensive and with nothing interesting to see. These might partly be misconceptions that can be corrected through a communication strategic effort. The best way to change this perception is by two different forms of communication. One will go from PADI Nordic straight to the divers through an email. This will have the purpose of getting their attention, making diving sound interesting and raise their awareness in preparation for the other part of the process.

Provmetod för olje- och partikelöverdrag från kompressor till tryckluftssystem

Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.

Rekreationsanpassad skötselplan för Skedalaskogen :

In this master thesis we suggest a recreational directed forest management plan for the Skedalaskogen. The forest is situated 10 kilometres east of the city of Halmstad and is owned by the municipality. We have in literature and in research investigated what people like and want in the forest, how to manage the forest for recreation according to for example tree species, mixtures and density. We tried to adapt the forestry methods more to recreational thinking. We have also looked at issues like what is rare and not rare in this part of the country according to nature and forest, where people live and which connection they have to the Skedalaskogen. The Skedalaskogen is a quite big area, totally 830 hectares. The area have about 100 000 visitors a year.

Lärarens skriftliga respons på elevtexter : Två fallstudier om lärare och grundskoleelevers inställning till respons

Syftet med denna undersökning är att ta reda på hur lärarens skriftliga respons uppfattas av elever och hur de arbetar med den samt hur lärare tänker kring skriftlig respons. För att finna svar har vi valt att använda en kombination av en kvalitativ och en kvantitativ ansats. Undersökningen har genomförts i form av två fallstudier i två olika utbildningsmiljöer. Undersökningen består av sammanlagt sex elevintervjuer, två lärarintervjuer och 41 deltagande elever i en enkätundersökning.Båda uppsatsförfattarna gör var sin fallstudie som innebär att intervjua en lärare och tre elever vardera samt genomföra en enkätundersökning. Undersökningen visar att eleverna i respektive fallstudie uppfattar den skriftliga lärarresponsen som positiv.

Möjligheternas skog : utveckling av Teleborgsskogen som tätortsnära rekreationsskog i samarbete med närboende och aktörer

The Swedish forestry aims primarily maximize production and economical wins. However, especially urban forests have great qualities as space for recreation and children?s play, which means that other goals should lead the forests management. The Teleborg forest is a wooded area in Växjö, surrounded by urban dwellings, schools, nurseries etc. A great part of the forest was wind felled during the storm Gudrun in 2005 which changed the forest, earlier dominated by spruce, dramatically.

Mätning av stamdiameter med markstående scanner :

Booth for operational planning of harvesting and for long term planning, data is today collected manually. Intensive objective field inventories are usually too expensive. To enhance optimisation of timber flow from forest to industry Moore efficient methods for measuring tree stems of standing trees are needed. The performance of terrestrial laser scanners have improved and these could possibly be used within forestry in the future. The objective of this study was to validate how a terrestrial laser scanner could be used to measure stem diameter, and to test how the errors depend on distance from the scanner and tree species. Two plots (one pine and one spruce) were used for this study.
