Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

Recent corporate challenges require effective communication in order to secure a company?s reputation. Companies as a result, need to be committed to a series of corporate social and environmental practices along with their financial commitments to their shareholders and investors. In fact, businesses are required to go above their ordinary operations and involve all potential stakeholders that can be affected by their strategies. Companies also need to communicate social, environmental and economic consequences of their activities along with their CSR commitments to their internal and external stakeholders in order to make a better corporate image and improve their market opportunities.

Since the early 1940s in Sweden, subsidies have been a recurring feature in housing politics.Throughout history, these have been used as a management measure to control theconstruction of housing and to promote the Swedish welfare state. The political parties aretoday disagreeing on how much responsibility the state should carry for citizens housing. Tosolve the conflict, the dwelling has to be defined. Is the dwelling to be considered a socialright, like education and healthcare or is the dwelling to be considered a product for the freemarket, driven by supply and demand?The positive population growth in Stockholm has lead to an increased demand for dwellings.The supply of dwellings has not been growing at the same rate, which has implied higherhousing prices and longer wait for rented apartments.

The competition policy in the EU should guarantee that the competition is not distorted in the way that would prevent or create difficulties for the free mobility of goods and services between Member states. It is prohibited for companies to abuse their dominant position according to Article 82, if it affects trade. The essence of Article 82 is control of market power. The perfect competition results when supply and demand appoint the price and quantity of a product. Firms are encouraged to compete then it results in efficiency, quality products and lower prices.

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

pcSKOG-gård is a computerised manager plan for private forest owners, developed by the pcSKOG AB. The program is based on forest stand data, joined with a map of the forest and GIS-applications. The purpose is to offer a program for private forest owners managing the forest and with the possibility of updating the actual status of the forest. The company pcSKOG AB is the leading producer of programs for forest management and has developed the program since 1997. The program is currently the most common program used by private forest owners in Sweden. The aim of this thesis, leading to MSc in forestry, is to investigate the purpose of the private forest owners when purchasing the pcSKOG-gård. The thesis also studies how private forest owners use the program, what they use it for and how the private forest owners state that the program has achieved to fulfil their expectations. The thesis is also a market research concerning the knowledge and attitudes the private forest owners have about the program and associated services. The study material has been collected during two phases.

This report describes the development of a system for controlling documents. The report starts with a problem description which the company wants an intranet-based solution for. The report then continues to describe the development phase for the different parts of the system which results in a complete system. The company that wanted this system is called Orbit One and is located in Ronneby, Sweden. They have had a problem with old documents circulating in different versions and in different binders. Now thanks to their new system they can access their documents easy and on demand through their intranet..

This study is based on interviews with six students from Stockholm that have shared their feelings/opinions about how they experience their identity as a student. The aim of this master?s thesis is to examine how the identity of students is constructed but also how the post modern society affects the life that the students are living. With a higher demand on education and responsibility of making the right decisions, the student?s main concern is not only her studies, but also the goal to succeed in her life.

To build a sustainable future should we first understand that; every aspect of our daily lives can affect the environment. It?s important that we take responsibility for understanding how we impact the environment and change our actions accordingly. The worlds total energy consumption equivalent to 80 million MWh / year. This corresponds to about 220 million MWh / day.Energy consumption is one of the main reasons for increased greenhouse gases when the reduction of this consumption has a great demand worldwide.In order to prevent the energy that consumed the buildings must be energy efficient but there is a conflict between radon ventilation and energy conservation in a building, given that ventilation can consume as much energy (currently 29-59% of energy-efficient houses use), especially in a cold climate as in Norway.

The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.

In this study the practical work with the EU Water Framework starts on the island of Gotland. 33 lakes and 32 streams have been characterized and classified regarding to their ecological status. The aim with the characterisation is to create a uniform discription of all waterbodies and a comparable estimation for the future. The aim with the classification is both to study the waterbodies ecological status and to gain knowledge of where the resources should be concentrated so that the ecological status in all waterbodies will be good in 2015.The characterisation has been done according to the EU Water Framework Directive, and the factors that have been applied are the mean depth and area of the lake. The length and size on the catchment area are the factors that have been used on streams.

The aim of this study is to examine the significance of having a music department at the public library in Enköping, and how the organization of the phonograms is handled. The different areas examined are the reason of the reintroduction of a music department, its budget, its users, the work with selection, the marketing, statistical data concerning loans, the work with classification, indexing, and organization of the phonograms and the future of the music department. The empirical material consists of qualitative interviews with staff connected to the music department at the public library in Enköping. For the theoretical frame, Sanna Taljas discourse analysis of music libraries in Finland is used. Talja presents three discourses which all show different views on what kind of material a music library should contain.

South Africa has been among the top ten wine producing countries for at least 20 years. Even though the land under grapevines is decreasing globally it is still increasing in Africa. The awareness of environment has strengthen the last years and South African producers experience a high demand of environmentally friendly produced wine, especially from the European market. This demand was the driving force behind the development of the world unique sustainability certification, Integrated Production of Wine (IPW), which is inscribed in the South African legislation. What makes this certification unique is that consumers can trace their product all the way back to the farming practices owing to the identity number specified on the IPW Integrity & Sustainability seal on certified products.

I den här uppsatsen har faktorer för en ökad användaracceptans och diffusion av Video on demand(VOD)-tjänster identifierats med hjälp av en litteraturgenomgång av tidigare studier i acceptans och diffusion. Litteraturgenomgången ligger till grund för en lista av faktorer som gör en konsument mer villig att anamma en VOD-tjänst. Faktorerna har sedan utvärderas genom en kvantitativ undersökning med hjälp av en webbenkät. Resultatet blev i stor grad det som förväntat där det framgår att utbud och kostnad är de viktigaste faktorerna för en hög acceptans, men även andra faktorer kan spela in som användarvänlighet, kvalitet och sociala faktorer..
