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.

Malmö has often been described as a segregated city, with relatively low democratic participation and high poverty and alienation. Behind this kind of statements we often find a material reality, with unequal distribution of assets and potentials that needs to be taken into consideration for political action. At the same time this categorisation of people into different groups can take stigmatising effects and result in increased inequality.I find the theoretical basis for my thesis in Lefebvre?s writings on ?the right to the city?, that shortly means that all inhabitants of a city have the right to take active part in the constantly ongoing process of producing and reproducing the city ? on all levels, from a hands-on everyday life level to a more abstract political level.With an interdisciplinary approach, where the right to the city is discussed in relation to citizenship, presence, representation and public space, I try to understand the connections between democracy, participation, justice and equality. These discussions are then applied to examples from Malmö; both publically initiated projects and individual physical markings in the city.

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.

Castration of dogs holds many reasons and opinions, therefore methods, traditions and rea-sons vary. The approaches have during time changed from mostly surgical castrations to also including hormonal treatments. Castration is used to control the dog's reproductive abilities, for medical reasons and to possibly rectify problems of behavioral nature. How common a particular method of castration is in a country is highly dependent on the country's traditions. In Sweden it is most common with castration for medical reasons, such as possible elimina-tion of diseases, for example, benign colorectal tumors.

Delia flies (Diptera: Anthomyiidae) are economically important pests in several horticultural crops. The control is commonly relying on chemical insecticides, though there are possibilities with biological control from the natural enemies in the field. An important natural enemy is the parasitic wasp, Trybliographa rapae Westwood (Hymenoptera: Figitidae) that lays eggs in the Delia fly larvae. The parasitoid larva and the host larva have a parallel development until the host dies within its puparium and an adult parasitoid emerges. The aim of this thesis was to understand the attraction to host- and food-associated plant volatiles of T. rapae, in order to enhance the effectiveness of the parasitic wasp as a biological control agent.

The Nord Stream natural gas pipeline has been a controversial project. The debate was primarily escalated by Poland's strong negative reaction to the project in the spring of 2006 over safety and security and then alternated back and forth in Europe until the approval by the nations most concerned in the Baltic region during the autumn of 2009.In the case study an approach is used that primarily maps out the media image of the various viewpoints that deal with the pipeline and how these viewpoints position themselves, primarily through political and environmental dimensions. Simultaneously there?s an attempt to map out the spatial spread of the media image views as to the proximity and distance to the pipeline in Sweden, Poland and Germany. A key question is whether distance or proximity to a large facility can affect people's attitudes.A parallel focus of the study is to explore the role of the Nord Stream natural gas pipeline in the cross-border hinterland region of Szczecin-?winouj?cie.

The limit for mercury in fish, set by health authorities, is exceeded in about half of the lakes in Sweden. Methyl mercury (MeHg) is the most toxic form of mercury and accumulates in fish. Therefore transformation of inorganic mercury (Hg) to methylmercury (MeHg) is an important process that we need to understand in order to possibly counteract the negative effects of mercury in the environment. The seasonal dynamics of mercury biogeochemistry is likely of great importance for the accumulation of MeHg in the aquatic food web. In thesis the chemical speciation and transformations of Hg and MeHg in bottom waters and sediments is followed in Ängessjön, a small lake located on the east coast in the middle of Sweden. The lake is not directly affected by any industrial pollution and concentrations of Hg in the sediment reflect the atmospheric deposition in this area, as well as processes taking place along the hydrological pathways from soil to lake. Samples from sediment, bottom- and streamwater were collected in average every second month during the period Feb.

Public libraries are mainly employing women and have female managers. According to theories based upon so-cial construction we create our roles together in our society. The role of a manager has for a long time been viewed as the role of a man. The objective of my thesis is to gain knowledge on how a few women that work as managers in public libraries perceive and describe their roles. A parallel aim is to let a few future librarians de-scribe their managers and their own views on leadership, with a focus on gender issues.

This diploma work project is a product development project which purpose is to redesign a braking system for a walking frame. The system that was developed diverges the force from the user to braking power, and includes a service brake as well as a parking brake. The most important components of the system are a grip handle on where the user holds on to and a braking handle on which the user operates the brake from. The system also includes a power transmission component, braking package and other mechanical components. All of the components wasn?t developed in this project, several off them has been reused from the existing system.This product has been developed to meet the requirements and standards presented from the principal, Ahlberg Leber.

The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.

Parallel to new technological advancements, including the development of interactive recommender systems, digital music services on the Internet, such as Spotify, have in a short time span gradually replaced former physical media such as CDs and MP3-players and become pioneers on a market with an otherwise uncertain future. By subscribing to the service, users have access to a vast library of music and from any device with Internet access. In order to provide a satisfactory and useful musical experience, different ways of coping with the vastness is required - which is precisely what recommender systems are for. Improved filtering techniques and use of devices built in sensors, make way for new opportunities of more precise and contextually tailored suggestions for track selection, which in turn leads to potential privacy issues when using interactive music services. But where do we stand today? By compiling, exemplifying and discussing three different perspectives with relating to the development of interactive music recommender systems, the objective for this paper is to provide a for science, industry and user, objectively nuanced account of current potentials and expectations.

Swedish forests are dominated by just two conifer species Norway spruce and Scotch pine. They are not able to achieve the highest possible production or fulfill industry demands for raw materials. The introduction of exotic conifers can potentially meet these shortcomings and present a relevant solution. This study was conducted in a block experiment with ten blocks planted in 1987 by SCA in North Sweden. The objective of the block experiment was to study if Black spruce is an appropriate alternative to Lodgepole pine, Norway spruce and Scotch pine on different site classes.

For Skattkärr IF a turf field with warming has been projected to increase field?s utilization hours and to have a longer period for athletes to perform their activities outdoors. The technique chosen to heat the plan is a type of a geothermal heating system without a heat pump. The brine, which is water with 30% ethanol, collects heat from the borehole and discharges it to a coil in the field. There is at position 11 boreholes but it is planned to increase the number to 31, which is the design for the facility.

This study has been conducted on behalf of Vectura Consulting AB with the purpose to examine how different actors perceive the dimensions of sustainability and sustainable construction. The purpose is also to provide an understanding of existing barriers and opportunities for sustainable construction within the industry and exemplify with different directions for the actors in order to develop sustainability. The study has approach the research problem by using systems theory, developed by Checkland, to identify the relevant system. Other systems theories has been used as an theoretical framework in order to identify barriers and opportunities, which in this study are based on Hughes?s theory about reverse salients and salients.

The requirements for wastewater treatment plants (WWTP) are gradually increasing, partly because of higher incoming loads, which in turn require a more efficient treatment process. In parallel with environmental and economic goals there are also desires to lower energy consumption without compromising the wastewater treatment. Furthermore, there is a demand on WWTP´s to alter eutrophication in aquatic systems through better nitrogen and phosphorus removal. An increasing number of WWTP´s have acquired biological nitrogen and phos-phorus removal. A by-product of this type of biological treatment is the formation of nitrous oxide, which is a potent greenhouse gas.
