During the last years, the importance of sourcing in firms has increased. Globalization, fierce competition and an increased level of outsourcing are common explanations to why firms have highlighted the potential to realize savings and the value creation that the Purchasing department can generate. One trend that follows in parallel with globalization is an increased pressure from society on firms to take responsibility for the impact that its products and services have on the environment. This responsibility creates even more attention as outsourcing involves trade with suppliers in low wage countries, where the level of environmental and social responsibility is not always satisfying. The Purchasing department, the firm?s interface with suppliers should therefore, together with the firm?s Environmental department, play a key role in the firm?s contribution towards sustainable development.

Tractors of today come equipped with a CAN-system. A CAN-system sends information from sensors to electronic control units who process the signals. The sensors measure several interesting parameters such as force, pressure and speed for various components of the tractor. This thesis discuss a force sensor which is placed in the pivot of the tractors three point linkage, the sensor measure the horizontal reaction force from the load that the tractor is exposed to. Signals from this sensor can be used to measure the force from any implement that the tractor is exposed to during an operation.

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

AimThe purpose of this study was to examine the relationship between physical strain and recovery in dancers at The Ballet Academy in Stockholm, Sweden. Research questions used to guide the study were: How great is the dancers experience of physical strain? Do any of the dancers show mental or physical signs of overtraining syndrome?MethodPhysical strain was studied by letting the dancers fill out a booklet catloging their intensity during practice. Utilizing a questionnaire, data was gathered regarding preceding year. To give more nuance to the data gathered, The Profile of Mood States was used to detect possible mood disturbance.

The prevailing urban migration is a worldwide process. This results in growing cities and a diminishing proportion of people living in the countryside. As the urbanization continues a large amount of the world?s population is expected to live in urban settlements of informal character by 2050. Green Belt has for many years been used to control urban growth and to secure the sustention of larger green areas around towns and cities.

The starting point of this study is national as well as international surveys which show that the study motivation and general level of knowledge among Swedish students have decreased. The Swedish Curriculum for the Non-Compulsory School System (Lpf94) states that each student shall be given the possibility to strengthen their will and ability to learn. The teachers are expected to play an important role in the effort to increase student motivation. The opinions of the students are a valuable source when trying to understand what motivates them. The purpose of this study is to provide a more profound understanding of what students express about their motivation in the interaction with the teachers.

På LKAB:s produktionsanläggning i Malmberget vill LKAB öka produktionskapaciteten med ca 20 % i anrikningsverket. Ett av flera alternativ för att uppnå en sådan kapacitetsökning är att installera en HPGR (High Pressure Grinding Roll) i en av Malmbergets sektioner. Tidigare studier av HPGR har visat på en möjlig kapacitetsökning samt en energibesparing. En försöksserie har genomförts för att undersöka hur väl Malmbergets malm (med interna specifika benämningen PAR) krossas i en HPGR samt om malmens malbarhet ökar. Testerna är genomförda på Hacettepe universitet i Ankara, Turkiet, med deras tryckutrustning anpassad för HPGR undersökningar.

The local politicians in Sweden are responsible for a great deal of the welfare system why one would assume that there are a lot of demands put on them - demands for certain skills or a certain level of competence. I have in this study tried to find out how the demands on the local representatives concerning the demands for competence and the actual level of competence among the politicians are affecting the local politics. This was done through investigating how the local politicians are perceiving their level of competence and the demands put on them, but also how the employees are perceiving the demands and the level of competence put on the politicians. The study was made in the municipality of Gislaved in Southern Sweden. I was using both quantitative method (an opinion poll among the politicians and employees in the municipality) and qualitative method (interviews with three politicians and three employees and literature studies).In order to investigate the demands for competence I split the concept into ?soft? competence (socially and emotionally based skills), and ?hard? competence (skills based on knowledge, education and experience).

Every plan and program decided on by an authority or municipality, where the environmental impact can be considerable, must be environmentally assessed according to Environmental Code, the Planning and Building Act (PBA) and the Regulation on Environmental Impact Assessment.The purpose of this study is to examine the Environmental Impact Assessment (EIA) for The Region Development Plan for the Stockholm Region, RUFS 2010. The plan was approved by at that time the Regional Planning Office (Regionplanekontoret), which procured the process by consultants. RUFS 2010 includes two merged plans ie. a regional Development Plan (RUP) and the Regional Spatial Plan for Stockholm. It was necessary to establish an environmental assessment of RUP, but not for the regional plan.

Den första serietillverkade hjulskotaren i Sverige presenterades 1962. Skotaren blev revolutionerande för mekaniseringen av terrängtransporterna. Hästarna ersattes och var i början av 1970-talet nästan borta från skogsbruket. Mekaniseringen innebar stor produktivitetsökning med ökade avverkningsvolymer. Hjulburna skotare har sedan introduktionen tills idag varit dominerande i det svenska skogsbruket. Under 2012 fanns ett fjortontal tillverkare av hjulskotare, vilka succesivt fått bredare hjul, mer avancerade motorer och transmissioner. Syftet med denna studie var att sammanställa tekniska data och försäljningssiffror i Sverige för hjulskotare tillverkade i de Nordiska länderna från deras introduktion 1962 fram till och med 2012 samt att besvara den frågeställning som ställts upp i studien genom att statistiskt styrka trender genom att testa hypoteserna H0: ?1 = 0 och H1: ?1 ? 0. Litteraturstudien har utförts med datainsamling av tekniska specifikationer samt årtal då serietillverkning av skotarna påbörjats.

Bakgrund: Trycksår har varit känt sedan ca 2000 f.Kr. ändå kvarstår problemet. Det är idag ett utbrett problemområde inom vården då patienter ständigt drabbas av nya trycksår trots att välbeskrivna preventionsåtgärder och riktlinjer finns att tillgå. Främst drabbade är äldre, personer som har någon form av rörelsehinder, är sängliggande eller stillasittande stora delar av dygnet. Trycksår innebär ett stort lidande för den drabbade patienten, främst i form av konstant smärta.

Denna enk?tstudie unders?ker vad f?rskolepersonal har f?r kunskap och erfarenhet av diagnosen selektiv mutism (SM) och tal?ngslan, samt om personalen anser att ytterligare utbildning beh?vs. Studien tar utg?ngspunkt i en brist p? forskning som fokuseras p? selektiv mutism i f?rskolan. Selektiv mutism ?r en ?ngestrelaterad diagnos som vanligtvis debuterar i f?rskole?ldern.

This thesis concerns how the power quality in the grid is affected by the connection of wind power plants. As things are at present, Fortum Distribution AB has a number of wind turbines and wind parks connected to the own grid. As the pressure on building and connecting additional wind power is increasing, so is also the interest of how the already existing wind power generation affects the power quality in the nearby distribution grids. The study is performed by direction of Fortum Distribution AB and is limited to the 10 kV/40 kV-grid in Bohuslän, Sweden. The methods for calculation of power quality are compared to the results of a number of measurements.

The residential yard at Kvarteret Landsfiskalen 1, in the area Herrgården in Rosengård, Malmö was built in 1971 and has since then been reconstructed twice, in 1984 and 2008. The yard is found in an area which was built during the years 1965 ? 1974, a period in which the swedish goverment approved a decision to build one million homes, and much of the events in this particular yard is also typical for the process in many other areas built during the same period.At the original construction the design of the yard was entirely incused by the pressure in time and finance, one was under at that time, in order to over- come the housing shortage. The design it has nevertheless been given, reflects the esthetic ideals of that time well.The building of the area was barely finished when the swedish authori- ties started handing out grants in order to support the rearmament of the outdoor environment in the areas built during the so called ?million program?.

Ungulates are causing conflicts between stakeholders due to browsing damage on forests and agricultural crops. At the same time there is a big demand of keeping high ungulate densities for sports hunting and recreational purposes. Movement patterns of ungulates are strongly correlated with forage availability. Therefore, measures affecting forage quantity and distribution might be a tool to reduce the economical losses in forestry without decreasing the ungulate densities and thereby decrease the conflict between different interest groups.This study investigated the potential biomass production and utilisation of marrow-stem kale (Brassica oleracea var. medullosa), at game fields in Misterhult, Sweden, as well as browsing effects on adjacent forests.
