Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.

This technical report describes the master thesis in material engineering called ?Testing of surfaced hardened materials conceivable for gears and shafts?. The work extents 20 academic points. Land systems Hägglunds manufactures and sells different kinds of combat vehicles and terrain vehicles. Since the demands for bigger and stronger vehicles increases all the time, so are the demands on shafts, gears and other transmission details.

För ca 11 500 år sedan började Weichselisen smälta bort från Stockholmsregionen och trycket som ismassan utövade på jordskorpan började sakta lätta. Sedan dess har markytan inom de tidigare istäckta områdena arbetat för att återfå sitt jämviktsläge. Detta har påverkat strandlinjens läge genom en kombination av den pågående isostatiska återhämtningen och den varierande eustatiska förändringen. Denna uppsats fokuserar på ett område i anslutning till Hammersta ruin ca 13 km norr om Nynäshamn. Strandlinjerna för perioden 500?1500 e.Kr.

Stereotypic pacing is frequently observed in captive carnivores, however the underlying causes of this behaviour remain somewhat unclear. One of these possible causes are unpredictable feeding signals, which may give rise to frustration and subsequent pacing. Animal keepers at Nordens Ark had noticed that their Amur leopards had shown stereotypic pacing in connection to the passing of ATVs (All Terrain Vehicles) used by animal keepers primarly when feeding the animals in the park. The aim of this study was to investigate whether the stereotypic pacing of the two Amur leopards at Nordens Ark were affected by the introduction of a signal associated with feeding. The leopards were trained by classical conditioning to associate the sound of a siren with the delivery of food by an animal keeper.

This final thesis is initiated by the wood fuel department at the Swedish forest company Sveaskog as part of a project which also involves two other final thesises. The overall goal of the project is to investigate Sveaskog´s possibilities to produce and sell different wood fuel assortments in Västerbotten and the southern parts of Norrland. The aim of this thesis is to investigate how much wood fuel Sveaskog can produce in the area during the next five years and what that would cost. Furthermore the thesis will investigate the total possible supply of wood fuel from all other possible producers in the area. Treated assortments are forest residues from final fellings, whole trees from direct wood fuel thinnings, non industrial wood and industrial by-products from sawmills. The main effort to investigate Sveaskog´s production possibilities has been made to calculate the possible annual amount of forest residues and fuel from wood fuel thinnings that can be produced.

This study is made on assignment by the local board of forestry in Skåne, Blekinge and Halland. The change of the forest law 1994 brought a new type of management plan. A more active planning was introduced in order to equate the environment goal with the production goal. The purpose with this study is to give a better picture of how planning for nature conservation in production forest is made and to develop support for selection of silviculture methods for stands with combined goals. With combined goals means production forestry with a reinforced consideration to both nature and culture, called PF-classified stands. This was done by: ? Describing silviculture models from the literature that are possible to use for stands with combined goals. ? Describing silviculture models that is used in practice in stands with combined goals. ? Describing how the classification of stands with combined goals is used. Which means, were in the terrain, with which frequency and in which type of forest PF-classification is used. ? Comparing differences and similarities of theoretical and practical used models. The study was done partly as a literature study and partly as an interview study of forest planners.

Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

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 Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.

Forestry and reindeer husbandry are entitled to use the same land for their operations. For this reason, conflicts occasionally arise between them. Soil scarification is a forestry operation which has a negative effect on the occurrence of reindeer lichen. Reindeer lichens are of crucial importance to reindeers and reindeer husbandry, especially in the winter when reindeers primarily feed on different lichen species (Cladina spp. and Cetraria spp.).

Saab Training Systems är ett företag i Saab-koncernen som utvecklar, tillverkar och marknadsför produkter för militär utbildning. Ett av de centrala systemen i företagets produktportfölj är det instrumenterade stridsträningskonceptet GAMER, i vilket soldater kan öva dubbelsidig träning samtidigt som övningsledningen via ett centralt styrsystem kan övervaka och interagera i övningsförloppet.I och med den övergång som skett i många av världens försvarsmakter, från ett tungt territorialförsvar till ett välutbildat insatsförsvar har kraven på den enskilda soldatens förmågor höjts avsevärt. Samtidigt har det även skett en övergång gällande den generella hotbilden, från att tidigare ha utgjorts av en annan militärmakt, till paramilitära grupperingar som ofta bedriver en gerillaliknande krigsföring. Dessa två faktorer innebär att även förutsättningarna för soldatutbildningen har förändrats.Som ett led i anpassningen till dessa förändringar utreds i denna rapport möjligheterna att utveckla soldaternas audiella upplevelse i GAMER. Detta för att skapa ökade förutsättningar för en komplett upplevelsebaserad inlärning, som inte bara övar soldatens förmåga att använda sig av den taktiska information som ljudbilden förmedlar, utan även förbereder soldaterna på bästa sätt för den främmande miljö som dagens militära insatser ofta innebär.Inledningsvis genomförs en ljudcentrerad användningsfallsanalys av en uppsättning grundläggande övningsscenarion.

Tjörns kommun har planer på att bebygga Almön, en halvö belägen på nordöstra Tjörn intill Tjörnbron. Projektet är avgränsat till området som benämns Almöstrand, vilket är Almöns västra strand, en kuperad sluttning med kraftigt lutande partier som idag till största del består av skogsmark. Syftet är att undersöka hur man på olika sätt kan planera vägsträckningen i området, samt placering och utformning av hus, med hänsyn till en rad olika parametrar. Undersökningen visualiseras slutligen i 3D, i form av renderingar från Revit Architecture samt en fysisk modell.Initialt genomfördes en utredning för att ge beslutsunderlag till projektet. Vidare gjordes en fallstudie vilken har använts som referens och inspiration till arbetet.

Summary The estate of Johannishus is situated in the south of Sweden and in the province of Blekinge, about 8 kilometres from the city of Ronneby. The main building together with the park represents the province´s only example of a well preserved estate environment from the early 1800th Century, and was declared as a historic monument in 1982 because of its unique role in the province. Johannishus Park has during 300 years developed in close relation to the main building, the landscape and the surrounding infrastructure. Each century and owner has had an influence on the park, which has resulted in an interesting visible cross-section of 300 years of Swedish garden history. Most noticeable today are the traces from late 19th Century, but in its oldest parts the park contains structures from the early 18th Century.
