This study was performed in collaboration with Moelven Skog AB, Örebro district. The purpose of the study was to review existing literature in order to describe the current status of harvester based measurement technology as the way to provide information for calculating payment to the forest owners. In addition to this, a short survey was conducted to find out how a switch to harvester based measurement would affect the administrative workload on timber purchasers working for the district. The literature study shows that the harvester measurement technology is ready to use if it is combined with well-established routines for control of the harvesters, methods for automatic quality indexing of the timber and ways of creating pricelists specially adapted for harvester measurement. Pricing each stem seems to be the most promising method. Stem pricing has several benefits.

The Kverneland Ecomat and The Ecomat Seeder has been tested in three different field studies. All the studies were conducted on soils with different clay content during 2005 in Säby outside Uppsala. In one of the trial spring ploughing with the Ecomat and spring ploughing and seeding with Ecomat Seeder were compared with conventional autumn mouldboard ploughing and spring mouldboard ploughing to conventional depth (22-23 cm). In this study the quality of the seedbed, the number of emerged plants and weeds, the pentration resistance and the yield were examined. Shallow spring ploughing (10 cm) with the Kverneland Ecomat has shown to be a good alternative to conventional autumn ploughing when growing spring crops. During the season 2005 tilling with the Ecomat resulted in a higher yield than conventional ploughing. In 2002-2005 the average yield for shallow spring ploughing was 4 percent higher than after conventional autumn mouldboard ploughing and 10 percent higher than after spring mouldboard ploughing to conventional depth (22-23 cm). In the other two studies, ploughing to different depth in the autumn with the Ecomat was compared with conventional mouldboard ploughing and stubble discing.

Den här rapporten behandlar ett system som använder en databas som lagringsplats för loggar. En bra metod för att hämta ut dessa loggar saknades och databasdesignen behövde förbättras för sökningar i loggarna. En applikation för att hämta och söka i loggposter från databasen skapades. En undersökning om hur databasdesignen kunde förbättras genomfördes också. Båda delarna gjordes i ett projekt för att de hörde ihop.

I Datainspektionens rapporter 2003:3 och 2005:3 har myndigheten granskat hur personuppgifter behandlas i samband med arbetsgivares övervakning av anställda. Resultaten av dessa rapporter har visat på förekommande brister i förhållande till personuppgiftslagen i många av de granskade verksamheterna.Mot denna bakgrund har en fallstudie av ett medelstort callcenterföretag genomförts för att ur ett tekniskt perspektiv undersöka hur väl personuppgiftslagen följs i samband med företagets övervakning av sin personal. Utifrån brister identifierade i fallstudien har en mindre kartläggning av liknande företag genomförts i ett försök att mäta graden av generaliserbarhet i de identifierade bristerna.De brister som har identifierats i fallstudien rör i första hand otillfredsställande rutiner för gallring av personuppgifter vid e-postövervakning samt avsaknad av information till de anställda om vilka kontroller som sker i samband med detta. Behov av en uppdatering av företagets IT-policy samt ett behov av en övervakningslösning för personalens internetanvändande kunde också noteras.Kartläggningen har givit antydningar om att liknande brister vad gäller rutiner för gallring samt bristande information kan tänkas förekomma även hos andra medelstora callcenterföretag.Slutsatsen av arbetet är att flera av de brister som uppdagades av Datainspektionen för fem år sedan tycks göra sig gällande bland vissa medelstora callcenterföretag även idag..

The population of seatrout and salmon are threatened by over-fishing in the sea and loss of spawning and growing habitats caused by logging activities in many swedish rivers. The knowledge of the spawning migration and the habitat use of the seatrouts and salmon are limited. This study analyse the upstream spawning migration of Atlantic salmon and sea-running brown trouts from the lower part of the rivers to their spawning sites in the rivers Vindelälven and Piteälven. A knowledge about the distribution of spawning sites in the rivers will help these fish population in future restoration programs. In the fishladder at Norrfors in the river Umeälven were 29 sea trout and 20 salmon radio tagged and subsequently released and followed during their spawning migration upstream Vindelälven. They were tracked on their position in the river once a week.

Today there are many system development projects that break both budget and time plan. Often this depends on defects in the information systems that could have been prevented. The cost of test can in some cases be as high as 50 % of the projects total cost and it's at the same time an important part of development. Test as such has moved its focus from the software it self and its faults to a wider perspective on whole infrastructures of information systems where assure a good quality is important. Sogeti in the Netherlands have developed a test method called TMap (Test Management approach) that can be used for structured testing of information systems.

The moisture content in 10 deliveries of tree parts and 10 deliveries of wood residues were measured with different methods to analyze the quality of procedure used at Dåvamyran today. At the same time a survey was made on the measure procedures used at heating plants in Sweden The majority of the heating plants in Sweden use weight and moisture content as base for payment but at some plants only volume. The moisture content is usually estimated by drying wood chips in an oven but few plants a visual estimation is used. At few plants moisture content is estimated spectroscopicily. The techniques using near infra read light and other electromagnetic are still at a test stage. The methods of measurement used today are quit unreliable for the individual deliveries and there is a risk for systematic mistakes.

På uppdrag av skogsstyrelsen skall beräkning av framtida potential för uttag av skogsbränsle (GROT) vid slutavverkning av skog göras. Skogsbränsle utgörs till stor del av GROT som är avverkningsrester i form av GRenar Och Toppar. Flera faktorer påverkar hur mycket skogsbränsle det blir vid uttag efter avverkning. Stora snabbväxande träd har en större gren- och barrmassa. I detta arbete har lämplig mark, beståndens ålder och sammansättning selekterats ut med hjälp av GIS för att erhålla största möjliga volym GROT.

This paper examines how to use different kinds of source material for building surveys. The studyexamines how to use legends, construction archaeological surveys and Ground Penetrating Radar(GPR) as source material, and use them against each other to ensure the reliability they have.As a starting point I used Gräfsnäs castle ruin in Alingsås, Sweden, as an example. Gräfsnäs castlewas probably built in the Middle Ages and was rebuilt through the ages until it became a ruin in thelate 1800s. The castle ruin is today Alingsås most visited attraction.The investigation has focused on three areas which are located in the very ruin; rescue tunnels, thecellar vault and the treasure.There are legends that describe how the castle lord of Gräfsnäs fled an attack of the Danes in 1612 ina rescue tunnel which ended at the beach. At the construction archaeological surveys carried out in1935-36 they found a sewer in the courtyard that was once served as rescue tunnel and ended in themoat.

In today?s modern age, energy consumption has become a major issue, both from an environmental viewpoint and cost perspective. Because of a rapid technologic change and increased costs of production of electricity, the demand to develop effective methods for energy efficiency industries have grown.The electricity-intensive industries, such as plastic industry, the demand to reduce energy consumption has grown significantly over the past 10 years, which have led to the development of different methods to determine and locate energy-consuming parts in the industry. This also means being able to prioritize and organize activities in the industry.In this study the measurements of voltage, current, power and PF performance on injection molding machines (K-TEC 275 form Ferromatik Milacron in Germany) with a focus to locate, within a machine, various measures that could improve energy use in the plastics industry, in this case RostiGP in Gislaved. These measurements have been carried out with the help of a power quality clamp meter to carry out time logs of the machines for some time during normal word rate.

In Sweden, reduced tillage usually means non-inversion tillage, where primary tillage is carried out using chisel ploughs or disc implements. Primary tillage method is mainly determined by the desired soil loosening and the handling of soil residues. The effect of tillage depth was studied in field experiments in Skåne, Väderstad, Uppsala, Örebro och Västerås in different crops; spring oilseed rape, spring wheat, winter wheat and spring barley.The experiments generally had a randomized block design with the treatments mouldboard ploughing, deep chisel ploughing and shallow chisel ploughing, in some cases also shallow discing and no-tillage. In the experiments the following parameters were determined: seedbed properties, saturated hydraulic conductivity, penetration resistance, number of emerged plants and crop yield (all parameters were not determined in all experiments. Root growth and draught requirement were determined in two separate studies. There were no significant differences between tillage depths in non-inversion tillage in seedbed properties, plant emergence or root development.

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

Flerträdshantering har sedan länge främst förekommit i gallringar och vid skörd av biobränslesortiment. På senare år har svenska och kanadensiska forskare även gjort tidsstudier på tekniken i slutavverkningar där resultaten visar på en ökning av produktiviteten. Inom Holmen Skog har tekniken använts i slutavverkningar under ett par års tid men kunskap om vilken typ av skog den bör användas i och potentialen är okänd. Syftet med denna studie var att kvantifiera potentialen för flerträdshantering i slutavverkning inom Holmen Skog och beskriva de skogliga förutsättningarna. Det gjordes även en skattning av produktivitetsökningen och en maskinkostnadskalkyl för flerträdshanteringens effekter på skördarens drivningskostnad. Studien utfördes enligt följande: Stamnotor extraherades från slutavverkade trakter där flerträdshantering användes.

The forest property Fagerdal 2:10 was donated to the Swedish University of Agriculture in 1995 by Erik Rönnberg. The dominating species is Norwegian spruce (Picea Abies) and the average age is high due to selective cutting. The aim of this study has been to analyze how the forest on the property should be managed and demonstrate how a better estimated forest data affects the future management. The impact of the management on the carbon stock of the property was also examined. A forestry plan established in 2009 by Skogssällskapet was used as a basis for the analyses.
