The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.

Through previous studies during my education, I have experienced that chemical deicing road salt is a known problem, mainly in southern Sweden. Road salt causes damage to the environment and also damage to vehicles and structures such as bridges, etc. Road salt causes vehicles and steel constructions to rust, leading to increased costs for repairs of damage to structures. Road salt also causes damage to the plants and the economy to suffer, when plant material and soil needs to be replaced. In order to get closer to a solution, I put up three questions.

Water is the most essential resource for life. In cases where drinking water is processed from surface water it is important to ensure the raw water is of good quality, and is suitable for processing through the water treatment plant.The drinking water for Västerås is sourced from Västeråsfjärden, in the western side of Lake Mälaren. The city itself is home to marinas, ports, a wastewater treatment plant, the Svartån outlet, sewage pumping stations and stormwater outlets. Because of the negative effects these activities have on surface water quality, Mälarenergi AB is interested in relocating the raw water intake point to Granfjärden, 10 km east of Västeråsfjärden. At Granfjärden the intake point would be less exposed to the activities in Västerås, and could be placed at a greater depth, resulting in better water quality.In this Master?s thesis the water quality and the pollution risks at Västeråsfjärden and Granfjärden sites are compared.

Purpose The purpose of this study is to evaluate the treatment results and adverse drug effects for 14 dogs receiving a new paclitaxel preparat named Paccal vet. The evaluated dogs are chosen to enter a pharmacogenomical study. Therefore, this paper intends to give an introduction to pharmacogenomics. Finally this study also aims at finding the homologue genesequenses in dogs to seven genes that are important for metabolism of paclitaxel in humans. Materials and metods The dogs went through 2-4 cycles of paclitaxel treatment, they received a new water-soluble formula named Paccal vet, at dosages of 100-150mg/m2. Treatment results and adverse effects are listed for each dog in table 1.

Logosol is a company that produce small-scale wood processing products. To be able to expand the business Logosol have decided to increase exports, their target markets are the US, Russia, Germany and Norway. The expansion has mainly been through subsidiaries situated on the abroad markets. The subsidiaries have done poor results and that has influenced the whole company. CEO Bengt-Olov Byström made a decision to sell out the units to the people who worked in the business.

This master thesis is performed at Scania Axles and Gearboxes, a production plant located in Södertälje. Within the plant axles, gearboxes as well as central gears are assembled from components to finished products. All production is conducted on production lines, with a pre-determined rate, which is supplied with components by the material handling department. Since the production quantity and the mix of product variants produced on the production line is customer order-based, the number and type of components needed for production as well as appropriate staffing within the material handling department is difficult to predict. Scania is currently using a number of different resource planning tools for each material handling-department within Axles and Gearboxes to visualize the workload within the departments.

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

The primary purpose of this essay is to study and describe how the concept of ?ethnicity? is introduced, defined and constructed at the Universities of Social Work Education through the perspectives of students attending and teachers/researchers currently employed at the University of Gothenburg. Also, this study attempts to describe what differences there are between the two groups and how these are expressed. The theoretical perspectives which we have used to analyse the empirical data are social constructivism and postcolonial theories. We have applied a qualitative method based on four interviews with teachers/researchers and two focus group interviews with 14 students.

Denna uppsats har till syfte att undersöka om det är möjligt att som pedagog tälja leksaker i en barngrupp medan barnen leker. Undersökningen har även inriktats mot om det egna förhållningssättet till själva utförandet av att tälja leksaker, kan ha inverkan på barnens lek. En frågeställning har då varit om leksakers utformning har betydelse för barns fantasiutveckling. Den egna utvecklingen av gestaltningsförmågan har också observerats. En kvalitativ forskningsmetod har legat till grund för undersökningen som kan jämföras med en aktionsstudie.

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.

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.

Trade was assigned as a Community responsibility at the founding of the European Community in 1957. It was then recognized that Europe would achieve a greater international influence if it were to negotiate trade deals with one voice. Since then, the basic rule has been that the European Commission negotiates agreements on behalf of the EC, and presents the agreements negotiated for approval in the European Council. Today, the 25-member European Union is the largest trading power in the world, and most member states have decades of experience of coordinating their national trade interests into a common position. However, partly as a result of the complex nature of the trade decision-making processes it is sometimes problematic to identify who or what really influences EU trade policy.

With today`s business world, it is very important to deliver the right product with right quality and quantity at the right time. By ensuring that the staff are happy and have the opportunity to work in a workplace with good structure, the company will be able to reach these parameters and at the same time maximize the efficiency.The project has been carried out at Stena Stål AB in Värnamo. The company's main task is to cut, store and deliver production steel and tool steel to processing companies in the surrounding region. Stena Stål AB in Värnamo is one of total 21 companies in the company group Stena Stål. Stena Stål is a part of the Stena corporate group which owns a total of eight different company groups that are spread in about 250 different locations in 14 countries.The purpose of this report is to give Stena Stål AB in Värnamo suggestions on how to design a new facility for tool steel.

In several countries that have been early in the development of wind farms, there is today a second hand market for the used wind turbines. The European Union (EU) has established a waste hierarchy in order to minimize throwaway mentality. The second hand market is a part of this as the steps are to minimize, reuse, recycle, extract energy and landfill.In order to promote the development of renewable energy, there are energy certificates for the producers that provide it, wind power being one type of renewable energy. After 15 years the energy certificates for a specific wind turbine are no longer paid, and after that there are several different scenarios for the wind turbine. The scenarios investigated in this bachelor?s thesis are export of the wind turbine to countries that are not as far along as Sweden in their development towards renewable energy, selling in Sweden to individuals, and recycling of the wind turbine, as it mostly consists of metals and therefore is recyclable.

Lake Bornsjön is situated 30 km southwest of Stockholm in a rift valley lake and consist three basins outstretched in northwest-southeast direction. The surface area is 6,7 km2 with a maximum depth of 18,3 meters, a mean depth of 9,8 meters and a retention time of the water of 6,5 years. The drainage area is 42 km2 and consists mainly of arable land (ca 1000 ha) and productive forestry land (2500 ha), but in the drainage area there are also restored and fairly newly constructed wetlands.Today the Stockholm area receives its drinking water from Lake Mälaren, but if there would be any pollution of this source, Lake Bornsjön would act as the water source. The area surrounding the lake was bought already in 1899 by Stockholm Stad for protection of the lake and was taken over 1993 by Stockholm Vatten AB. It has been a water protection area from 1988 and it was also accepted as a nature reserve in 1995.
