Utvärdering av labpilot - flödesbatteri : Experimentell studie

Results have shown that flow batteries may be a solution in the future as an effective and environmental friendly method to an energy storage system (ESS). The technology is reliable and has a high efficiency that comes with low energy losses and a long lifetime. The range of possible fields is suitable for cutting energy peaks in the power grid, by always have a ready and available energy storage that balances the production. By comparing the advantages of flow batteries with conventional batteries it is mainly the fact that they can conserve energy for a long time without being self-discharged thanks to that the storage capacity is in principle endless and limited by the size of the electrolytes tanks that makes them a great energy storage system. The batteries won?t take any damage or decrease in performance when charging or discharging it or if you exhausts it to 100 % and leave it discharged for a long time.

GRAVMONUMENTET I HÄLLSTAD: ETT VISUELLT SKÅDESPEL FRÅN 1100-TALET

The aim of this master thesis is to study the reliefs of a Romanesque tombstone from 1130 AD, with the intention to form a plausible understanding of their meaning. During the course of the investigation, my main focus will be on collecting materials of an iconographical and historiographical nature, as they appear in previous studies. I will also use performative analysis when examining the tombstone. Consequently this thesis can be seen as a survey of history and place; early Christian iconology as well as the experience of the viewer. As a result, the 900-year-old tombstone will not only be seen as a memorial in this text, but also as a performance of one man?s faith and as representing the core message of the early Christian church.The tombstone is a rarity in Swedish art history and well worth a closer examination.

Aim: This study was to describe health professionals´ thoughts and actions about the pressure ulcers.

En studie om Scandic Hotels miljökommunikation

The school is under constant change and school reform on the conveyor belt. In 2009 the Swedish government introduced new directives for the elementaryschool, including multi-national sample, written testimonials from grade one and grade with several grades rose from grade six. The purpose of this study is to examine currently active primary teacher perceptions of the pupils' learning and development might be affected by those earlier and clearer knowledge assessments, and how teachers perceive this reform on the basis of the Swedish school's motto "a school for all". The study was carried out with a phenomenological approach where the method has been depth interviews with five active primary teachers from grades one to six in a school. The results show that teachers perceive that the earlier and clearer assessments will affect students differently according to student performance and knowledge.

Pedagogiskt drama i undervisningen : En kvalitativ studie om vad pedagogiskt drama innebär för fyra utvalda lärare och hur de använder sig av pedagogiskt drama i undervisningen

According to the curriculum for primary schools, pre-school and after-school Lgr11 says that students should experience different feelings and moods using different forms of expression including drama (Lgr11 2011:10). The purpose of this study was to examine how educational drama is used in three elementary schools and for what purpose in teaching. The aim was also to examine the four teachers' perceptions of what educational drama means to them.I have used a qualitative approach with interviews and contacted four teachers from three different schools to get different information for my study. Three of them were educated teachers and one of them was an actor. The information provided in the interviews was analyzed using educational drama theory and previous research. The interviews with the teachers and the actor showed the use of different methods of educational drama in education.

Analysis of Quality of Service of Wireless LAN for IEEE 802.11e

Nowadays Wireless LAN is playing a more and more important role in network systems. After 1999, in which the IEEE organization published its Wireless Local Network standard 802.11[1], many people saw the advantages of the standard but also the lack of support for multimedia streaming. A lot of research work has been done on the proposed IEEE 802.11e standard draft during the past 4 years. It is supposed to be able to fully support Quality of Service. The final version will be published early in 2004.

Våga fråga: Faktorer som påverkar psykologisk trygghet i team

This thesis aims to further study the interpersonal risk taking within groups and thereby the importance of a climate promoting a reflective behavior. The increased demand in complexity and exposure towards teamwork leads to increased call for knowledge integration, which can be explained as the ability to integrate the collective knowledge within the group. We have therefor identified a need for better understanding what makes a group more effective. Key factors for self-estimated effective collaboration have been shown to be a group's reflective behavior and ability to coordinate the skills that each individual possesses. These factors are greatly affected by the psychological safety within the team.

Hjulspår på banken : En kvalitativ fallstudie om vägarna mellan lean och motivation hos anställda i tjänstesektorn

Background: Since the coining of the phrase lean production by Womack, Jones and Roos in 1990, this mass production system of Japanese origin has been implemented in a multitude of organizations throughout the world, the results being predominantly positive from a financial point of view. The possibly negative effects of mass production on worker motivation have been discussed since quality of work life became an important political issue in Sweden in the 1970?s. As the popularity of lean service is now increasing, there are still unresolved issues regarding the transferability of a mass production system to the service industry, particularly with regards to the motivation of service employees.Purpose: The purpose of our thesis is to study the lean system of a Swedish bank, SEB Way, from a management- as well as an employee perspective in order to describe how lean may affect the work motivation of service employees.Research procedure: The study is empirically based on observations and interviews on multiple hierarchical levels at SEB. We have conducted a total of 13 interviews with front line employees at SEB, with the central SEB Way team as well as two external lean specialists.Results: The study indicates that SEB Way has little direct influence on the intrinsic work motivation of the SEB front line employees, as work motivation was present prior to the implementation of lean.

Att lova guld och grön energi : En diskursanalys av svenska energibolags CSR-rapporter

The environmental situation is becoming increasingly critical. The energy sector and other industries have a big impact on our climate and the public is raising their voice for companies to admit their responsibility towards the environment and society. Companies engage in corporate social responsibility (CSR) and happily disclose their responsible performance in annual reports. But what messages are they conveying in their CSR-reporting, and what attitudes towards CSR can be found underneath the explicit content? The aim of this study is to discover which discourses exist in CSR-reports from Swedish energy companies, and how these discourses operate.

Itrakonazol till häst : en farmakokinetisk möjlighet?

Itraconazole is a third generation azol, a fungicide which acts by inhibiting ergerosterol synthesis in the fungal cell membrane, and thereby disturbing fungal regeneration. It has proven to be less toxic, to have a broader spectrum of activity and to be more potent than its predecessor ketoconazole. Itraconazole is only available in therapheutics approved for human use. Pharmacokinetic studies has been performed in humans, dogs, cats and laboratory animals. Although itraconazole has been used tentatively with good effect against fungal infections in horses, no pharmacokinetic studies have yet been done.

IT-Instrument : En intervju-och observationsundersökning kring användandet av digitala instrument inom undervisningen i ämnena historia och engelska i en gymnasieskola

This essay is a study of the use of IT technology by teachers of English and History at a Swedish upper secondary school. It is based on four interviews and four observations. In my analysis of these I have made use of the theory of Social Shaping of technology, a theory which puts emphasis on a teacher´s purpose regarding the use of IT technology in order to empower the teaching process. As a researcher I aim to explore the reasoning on the part of the teacher and to that end I use the method of interviews and observations. This study shows different ways of using IT technology varying from one teacher to another.
