Over an extended period of time there have been plans to establish a shared facility in Lennheden to extract groundwater from the Badelunda esker to provide drinking water for the cities of Borlänge and Falun. The city of Falun is dissatisfied with the quality of its drinking water and the city of Borlänge is concerned about the risk of contamination of its existing groundwater supply at its current location. To provide a basis for a decision on this issue, the company Midvatten AB has been commissioned to perform hydrogeological investigations in the area of Lennheden.The purpose of this thesis is to design a functional groundwater model of the area between Lennheden, place of planned extraction, and Övre Tjärna, place of existing extraction, to get a better understanding of the groundwater situation in the area. A groundwater model enables simulations of different scenarios in risk assessment and contaminant transport. The aim of the thesis is that the model can be used as an aid in Midvatten?s investigations in Lennheden and that it also can be used in future projects in the area.The model has been made in Processing Modflow 5.3 and encompasses an area of 19,5 × 11 km along the Badelunda esker and the river Dalälven between Djurmo and Frostbrunnsdalen.

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.

Under utbildningen inom samhällsbyggnad med inriktning stadsplanering på KTH har det funnits två teoretiska koncept som varit centrala och återkommande: hållbarhetsbegreppet med de tre aspekterna ekologisk, ekonomisk och social hållbarhet, samt kommunikativ planering. Dessa två, inom teorin till stor del skilda tankesfärer har under utbildningen däremot sällan diskuterats i relation till specifika praktiska kontexter varför deras kompatibilitet inte problematiserats. Denna uppsats ämnar därför utforska hur en planeringsprocess präglad av ideal om hållbarhet och kommunikativ planering kan se ut i praktiken samt diskutera vilken potential en planeringspraktik inom detta teoretiska gränsland har att svara upp mot de ideal om hållbarhet och medbestämmande som den är präglad av. Mer specifikt ämnar uppsatsen undersöka frågeställningarna:Hur ser en planeringspraktik styrd av ideal om hållbarhet och kommunikativ planering ut?Vilka begränsningar och möjligheter kan en sådan praktik vara präglad av?Studien är tvådelad och inleds med en litteraturstudie av de två teoretiska koncepten hållbarhet och kommunikativ planering för att undersöka deras kompatibilitet från ett teoretiskt perspektiv.

The main purpose of this study was to determine the self-estimated levels of knowledge about doping for a group of strength training young adults, and also to get an idea of their attitudes regarding the subject. A part of the purpose was also to investigate the potential associations between knowledge and attitude. Method: To collect information a questionnaire was constructed that was inspired by a similar study and in consultation with the tutor. Questions regarding background, doping and training experiences together with self-esteemed attitudes and knowledge about doping were included. Questionnaires were handed out at gym facilities in central Sweden, and were answered by men and women ages 18 to 35 years.

Subclinical mastitis (SCM) is a well-known problem in the dairy sector, where it causes severe economic losses mainly due to reduced milk production. This is a problem not only in the western world but also in developing countries. Surveys from different developing countries have shown a SCM prevalence of 52.4 ? 88.6 % at cow level and 26.7 ? 63.2 % at quarter-level. To combat mastitis is important to optimize the milk production of the cow.

Syfte ? Studiens syfte är att öka kunskapen om hur fordonstillverkares affärsmodeller påverkas vid förändring av statliga regelverk genom att studera ett framtida införande av HCT i Sverige. HCT, High Capacity Transports, är ett samlingsnamn för lastbilar som är tyngre och/eller längre än vad gällande lagstiftning tillåter. Regelförändringen övervägs för att sänka kostnader och miljöpåverkan. Metod ? Arbetet har genomförts i form av en case-studie.

Allanblackia is a genus of trees that grows in the rainforests of West, Central and Eastern Africa. Its big fruits contain seeds very rich in oil which has been used by local communities for cooking and making soaps. The native stands are threatened by overexploitation and the demand for the oil is much greater than the supply. Domestication programs, aiming at introducing the trees to small holder agroforestry systems, have been started for some of the species. The main aim of this study was to investigate the soil requirements of Allanblackia stuhlmannii in terms of chemical and physical parameters, as revealed by the soil conditions in native stands. Another aim was to see if these varied along an altitudinal transect.

When rubber equipment in a milking system ages, physical and chemical deterioration occurs and cracks, crevices, as well as deposits of organic and inorganic material is formed on the surface. Bacterial colonization can accumulate, especially on ageing rubber equipment and if the cleaning procedure is not functioning properly. Formation of biofilm in milking equipment could in turn cause bacterial contamination of Bulk tank milk. ATP bioluminescence is a fast and easy way to determine the hygienic status of a surface based on its ATP content, and results are given in relative light units (RLU). The method measures both bacterial contamination as well as residues from other organic material.

Enaforsholms mountain garden is situated in the western parts of the Swedish province Jämtland. This means a maritime climate. After a donation made by wholesaler A. W. Bergsten the country estate became KSLA property in 1937.

In the last decade, member states of the European Union have adopted a range of measures to decrease the dependency on fossil fuels. This has led to an increased use of biomass in heat and power production. In some countries, the lack of forest resource has led to large scale power producers importing their biomass needs. Due to high energy content and homogeneity, wood pellets have become an internationally traded commodity used for large scale power production. The Baltic States have emerged as one of the largest wood pellet exporting regions in Europe.

In Sweden plans to build high speed railways have been around since the early 1990s and the planshave developed to be more precised since. The future Swedish high-speed rail network is supposedto consist of two lines. Götalandsbanan; from Stockholm to Gothenburg, and Europabanan fromJönköping through the Öresund Region to Hamburg.The description of the aim to build high-speed railways in Sweden has in former reports always beento achieve rapid passenger traffic between big Scandinavian cities and Europe. There are almostnothing mentioned about the possibilities of high-speed transports of cargo on these railways. Thisstudy aims to clarify the freight transport market for Götalandsbanan and Europabanan.Today there is only one transport system with high-speed freight trains.

In Automatic Milking Systems (AMS), cows are kept in a free stall barn equipped with one or several milking units (MU). The cows? activities in the system are called cow traffic. There are three types of cow traffic systems: guided, partly-guided and free. Free systems have no gates, allowing the cows access to the feeding and resting areas at any time.

De stora fotbollsligorna i Europa spelar höst till vår, medan vi i Sverige spelar vår till höst. Då vi i Sverige kan se problematik med låg täckningsgrad och slitna gräsmattor under vår säsong, vad händer om vi skulle spela mellan höst till vår? UEFA ställer krav på att fotbollsplanen skall vara spelbar för alla matcher under säsongen. Problematiken på svenska fotbollsarenor under vintern är den låga temperaturen och dålig ljustillgång kombinerat med mekaniskt slitage. Syftet är då att belysa problematiken med att upprätthålla en tillfredställande spelkvalitet på naturgräs i fotbollsarenor. Uppsatsen avgränsar sig genom att behandla problematiken i Skandinavien och främst södra Sverige. Ekonomi, konstgräsbanor, dränering och värmetillförsel berörs endast ytligt.
