Innovationsupphandling : Innovationspartnerskap, ett upphandlingsförfarande med genomslagskraft genemot befintliga förfaranden för upphandling av innovativa lösningar?

The frequency of innovative procurement is currently very low in Sweden. Innovative procurement is to procure unknown solutions to a defined problem or need for which it sometimes has not yet been established on the market.  Current Swedish procurement legislation does not prevent innovation procurement, however, it limits official authorities to actively work with innovative companies to develop new solutions. Furthermore, some conflicts arise between the Swedish procurement legislation and the basic principles concerning public procurement developed under EU law, which must be considered in all procurements. Additionally, there is not a specific procurement procedure designed for innovative solutions in the current legislation.On the 15th of January 2014 three new directives on procurement rules were adopted with the general objective to simplify the procurement process and to make the whole system more flexible. A new procurement procedure has also arisen called innovation partnership.

Jämförelse av stenull- och polyuretanisolering : Brand- och fuktegenskaper i passivhuskonstruktion

This report compares two different types of insulation with regards to fire and moisture. The materials were tested for the company Fiskarhedenvillan AB, for a wall and a roof construction that the company currently uses in the establishment of Sweden's first certified passive house for international standards.Their current material, Rockwool, is compared to a relatively new material on the Swedish market called SEALECTION Agribalance sold by the company ISO Green AB. The material is a type of polyurethane insulation. This insulation material would result in a more efficient execution of the construction as it provides waterproofing and is applied more easily than Rockwool. From a fire standpoint, literature studies and discussions with fire experts led to results.

Frånluftsvärmepumpens möjligheter i flerbostadshus

If a building is heated by a heat pump, it is of high importance that the heat pump has a high coefficient of performance. An exhaust air heat pump extracts heat from the building?s exhaust air. The air has a relatively high and constant temperature all year around, leading to a high seasonal coefficient of performance. This thesis examines whether it is profitable to complement an exhaust ventilation system with an exhaust air heat pump in an apartment block that already has geothermal heat pump, district heating, oil- or biofuel heated system.

KLIMATTOLERANS HOS URBANA TR?D I G?TEBORG: Analys av klimatgr?nser och framtida klimathot

Urban trees contribute significantly to our society. By providing ecosystem services and a habitat that other urban species and ecosystems depend on, both biodiversity and the people in the city benefit. Some characteristics that the trees possess include functioning as biological filters for the atmosphere and water, as well as positively impacting people's mental health. However, urban trees are challenged by stressors such as pollution and a drier environment, making them particularly sensitive to climate change. The goal of this study was to estimate the expected magnitude of climate change in Gothenburg and compare it with the current urban species' natural climate boundaries to understand the extent of the climate threat and which species appear to be most at risk.

Redo för arbete : En studie kring arbetsförmåga hos personer efter förberedande arbetsträning

In recent decades, mental illness has increased in Sweden, and in parallel to this there has been an increase in unemployment. This implies that it is harder for people who have been away from employment for long periods due to ill health to return to work. The purpose of this study was to examine the work situation of people with mental illness who had undergone prevocational training, and to identify psychosocial factors relevant to their current work ability. The aim was also to describe how those who had undergone prevocational training perceived that it had affected their work ability. The study involved 19 participants who were interviewed and assessed with the Worker Role Interview, and an open question was asked about how they perceived that the prevocational training had affected their current work ability.

H2 För racing

AbstractMotor sports have been around as long as motor vehicles have been. Sports are often seen as costly polluter but in the same time the motor sports have encourages a large part of development, both for vehicles and other industries. Inventions like rear mirror and ABS brakes come from motor sports. One way to once again drive development forward while making motor sports carbon-neutral is to run the race cars on hydrogen. In this thesis, the goal is to convert a spark ignition engine for hydrogen operation.
