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.

De grundläggande värdena för statsförvaltningen är demokrati, rättssäkerhet och effektivitet. I denna studie undersöks det hur rättssäkerhet och effektivitet förmedlas på Skatteverket, hur tjänstemännen på Skatteverket hanterar dessa krav och i vilka situationer det kan uppstå att tjänstemännen måste prioritera mellan dessa krav. I kapitlet den offentliga förvaltningen och tjänstemännen redogörs det för den teori och den tidigare forskning som använts i denna studie. Den teori som använts är Max Webers teori om byråkrati och tjänstemän. I den tidigare forskningen beskrivs det hur kraven på rättssäkerhet och effektivitet behandlas inom statsförvaltningen och det redogörs för två reformer som genomförts inom den offentliga förvaltningen de senaste årtionden.

The first aim of this study is to examine what the differences are between the Classic directive (directive 2004/18/EC of the European Parliament and of the Council of 31 March 2004 on the coordination of procedures for the award of public works contracts, public supply contracts and public service contracts) and the Revised Classic directive (directive 2014/24/EU of the European Parliament and of the council of 26 February 2014 on public procurement and repealing Directive 2004/18/EC) when it comes to social considerations in public procurement. The second aim is to examine if the revision of the directive has solved the prior existing problems regarding social considerations in public procurement. In this paper a traditional European legal method is used. The examinations show a number of things, including the Revised Classic directive involving codification of case law, references to other sources of law and some clarified rules as well as new provisions. The regulations regarding reserved contracts, technical specifications, and selection criterion are satisfied in the Revised Classic directive.

As trading through advertisements increases, for example via advertisement websites such as Blocket, trading and contracting between individuals also increases. The contract law is the applicable legislation when individuals are trading between one another, because of the fact that individuals are to be considered equal against each another, and no consumer protection provisions are applicable. The contract law is not compelling, and general principles of contract law are therefore frequently applied within the legal area of contract law.Consistent declarations of intent shall have been delivered from both parties for a binding agreement to have been concluded. The declaration of intent, for example tender and acceptance are examples of a will to legally act. Other than tender and acceptance, the declaration of intent is usually difficult to establish and determine.In the event of the commencement of a negotiation stage between the parties, the declarations of intent are not deemed to be binding, but rather binding in the sense of a moral attachment for the parties.

Today´s roofing of dwelling houses is a very time consuming procedure, which includes a lot of different steps on the construction site. Not only does it cost a lot of money, but often do problems with rot and mold occur in the attics of houses today. The use of prefabricated modules has seen a great breakthrough in the field of construction of dwelling houses; at least when it comes to foundations and walls, where this type of approach makes the construction process way more efficient. What no one previous has succeeded to develop is a corresponding system for roofs that meets the demands of a dwelling house. Accordingly the goal of PlusTak has been to come up with a proper module system for roofing of dwelling houses, where the roofing is completed to meet the demands of the Scandinavian market. During the project a lot of effort has been put into customer contacts and the usability of the product, as well in the manufacturing process as on the construction site. This development has gone hand in hand with several practical tests and tryouts.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

The starting point for this master thesis was the product of the company "Humlegården", which allows its tenants in office buildings to follow their electricity consumption in real time, through their Smartphone's. The idea that resulted from that application is to investigate if it is possible to direct the tenants in office buildings to reduce their energy consumptions, but also to be satisfied with the indoor environment. This work addresses the factors which are the main energy consumers in office buildings. It addresses legal requirements and standards which are important to follow in order to achieve good thermal comfort in buildings. Some of them are physical climate factors like thermal environment, air quality and lightning.

This thesis, designed as a case study, is about complications concerning conservation of a decorative oil paint on lime plaster from the drawing-room in Mostorp castle sited in the county of Halland in south-west of Sweden. The building was built 1878-80 with an exterior of granite. The interior walls were made of clay bricks, lime mortar and lime plaster. The oil paint is applied to a layer of putty. The combination of different materials, which are organic and inorganic, affects the movement caused by internal and external stress.

In order to optimize calf welfare and health it is important to know the behavior of cattle in free ranging conditions. When the cow is about to give birth to a calf she will leave the heard about 12 hours before. It is then rather obvious that isolating the cow about calving time in a single pen is imitating the cows? natural behavior. To save space and minimize building cost it?s common that the farmers build calving pens for four of five cows especially at larger farms.

 Prostitution has been intensely debated in Sweden for nearly four decades. Two major investigations have so far been initiated by the government and numerous propositions have been put forward in the Swedish parliament resulting in the sexköpslag from 1999 that criminalizes purchase of sexual services. The law aims at punishing the buyer and protecting the women in prostitution, thus making it possible for women to be helped by various social interventions rather than punished. Swedish society has undergone major changes in these decades. Globalization, the internet and the membership in the EU have changed the Swedish society and influenced the discourse on prostitution.This paper has a twofold aim, on the one hand investigating if and how these changes have had an impact on the prostitution discourse in texts produced by the government and analyze how female and male sexuality in connection to prostitution is constructed.

This essay focuses on different aspects of the concept of freedom of speech. The purpose is to examine the opinions and thoughts that upper secondary school students have on rights, responsibilities and limitations when it comes to freedom of speech, and to investigate theirschool experiences of the mentioned freedom. Focus groups have been used as method and two group interviews have been conducted, one at a vocational and the other at an academic upper secondary school. Overall, nine students from the third grade participated in the interviews.The essay's results show that the students believe that everyone in society should have theright to be heard, whether you have extreme or divergent opinions. The interviewed studentsexpresses that all people have great responsibility for their opinions, however that, opinionsdiffer on how to interpret the concept of responsibility.
