Urban vindkraft : Vindkraftsprojekt Järvafältet & vindkraft i Sverige

Wind power is an energy source that is becoming increasingly popular in Sweden and around the world. The establishment of large wind farms supply and contributes to energy production within grid in search of a more sustainable energy production. Wind power is becoming more popular and opens up new areas of implementation. More cities are starting to use small-scale urban wind power, everything from full-scale work for a little less work adapted to the villas. Sweden has high goals regarding the production of green electricity and the work which deals with the conditions Sweden plays in achieving those goals.

Elanslutning av fartyg i hamn : en studie om förutsättningar och konsekvenser för Köpings och Västerås hamn

The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.

Bibliotekariers och universitetslärares syn på informationskompetens

The purpose of this thesis was to investigate on what perspective or perspectives university teachers and librarians at a medium-sized university in Sweden base their view on information literacy. More specifically, how do the respondents view their own information literacy and what opinions they have of their students? information literacy as professionals. Three perspectives are used to interpret the results, the sociocultural perspective, the phenomenographical perspective and the behavioristic perspective.The method used is semi structured interviews with three university teachers and three librarians.Both librarians and teachers emphasize the importance of information literacy, for themselves as well as for students. The information literacy of the librarians involves being well acquainted with the subjects of the students.

Peltierelement - spillvärme till el : Peltier element - waste heat into electricity

The purpose of this thesis has been to determine experimentally how good a peltierelement is to convert waste heat from wood burning. Three different peltier elementswere used in a comparison study. The comparison was mainly done to know howmuch power could be obtained from each element. Even, a circuit with a step-upfunction has been created to give a higher output voltage than the peltier elementitself. The result of the experiments was a low output power, the highest valuereached 2.18W.

Storleksoptimering av en etanolfabrik för integrering med ENA Energis kraftvärmeverk. : Baserat på en regional energibalans mellan tillgång på etanolbränsle i Enköping kommun och producerad etanol med hjälp av tillgänglig ånga från ENA kraftvärmeverk.

AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power.  ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant.  As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol.  Etanolens framtid vilar på bra lösningar för framställning.  I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle.  Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.

"Du måste helt enkelt äga ditt klassrum" : En studie om lärares ledarskap och strategier i mötet med störande elever

The title, ?You simply must own your classroom?, is taken from a quote from one of my informants.After review of earlier research on how teachers handle their leadership in the meeting with disturbing pupils and which strategies they use to solve problems in the classroom, interesting questions developed. What experiences do teachers have of disturbing situations in the classroom? Which strategies do they use to solve the problems? What kind of support do the teachers consider necessary in teaching? Are there any differences in teachers? experiences and strategies between the two selected schools? The study is supported by earlier research that deals with pupils? and teachers? perspective and strategies in different classroom cultures in terms of norm-breaking behaviour of pupils. The study is also supported by three different theoretical perspectives such as power structure, social order/disorder and support strategies.I conducted the study through interviews with sex teachers who work in the same municipality but in two separate schools.

Att driva etablerad Buddhistisk och Muslimsk verskamhet i Karlstad kommun : De verksammas uppfattning om möjligheter och svårigheter som religiös i Karlstad

I wanted to focus this essay on the operative?s perspective of running religious organizations in the city of Karlstad and to see positive and negative aspects of their day-to-day life working with their organization, following up with a comparison of the difference and the similarities between those groups. After delimitating which groups I was going to examine, I implemented a qualitative study of four people, from two different religious groups, whom I performed interviews with. My method of performing these interviews and understanding the perspective of the informants, I had a semi structured interview guide along with a recent study that was opting for similar conclusions, only in a different county and with different input perspective. The result of my study showed a difference in establishment of their region but with a lot of similarities in problems with their religious and structural premises.

På olika villkor : En intervjustudie om häktades och kriminalvårdares upplevelser av häktet

Different Perspectives is a study of detainees' and guards' experiences of the remand prison. The result of the study shows that the remand prison brings forth the individuals anxiety, stress and fear. The individual detained in remand prison have a great need for contact with their families, but also with the guards. In the remand prison there is always a great level of control and always some kind of power practised. It is the guards who have the power and the competences to make the individuals detained in remand prison follow the rules and do what they have been told.

Saklig grund för uppsägning av personliga skäl : ? En studie som ämnar ge en klarhet i vad kravet på saklig grund vid en uppsägning av personliga skäl innefattar.

The main purpose of this study is to investigate and with it clarifying what is meant by a dismissal for personal reasons must be based on valid reasons. More specifically, what is valid reason and what is required for that demand to be regarded as fulfilled.To my help to achieve this I have asked questions such as what kind of behavior from the employee can be the basis for a valid termination of the employment, what factors do the court put emphasis on in a trial and what is the requirements for the employer during the dismissal.The study has further objectives which are to illustrate the phenomenon of valid reason from a diversity perspective and from an international perspective. To achieve those objectives following questions have been asked: Is some groups covered in a greater extent than others by the requirement that a termination of employment must have valid reasons and are there international counterparts to the Swedish requirement that a dismissal must be factually based.What emerged from the study judicial inquiry is that the phenomena to which the employee is guilty of first is to see as valid reason when the employee are aware of the obligations undertaken in the employment but acting against them and inflicts some sort of damage for the employer.With regard to the employer's obligations in a termination proceeding are they to see as comprehensive and can be summed up to the fact that the employer should do everything in his power to avoid a dismissal.When it comes to the factors a court should take into account is this also a matter of major proportions. The court shall take into account all of the circumstances relating to the dismissal, which means that, with absolutely certainty, determine in advance what the court will decide is an almost impossible task.Furthermore, it emerged from the study that the requirement that a dismissal for personal reasons must be based on valid reasons may come to certain groups of workers to a greater extent than others. The study's investigation also indicates that the Swedish legislation, as it reads today, probably in breach of regulations enacted by the European Union.   .

Vad betyder Gud och livet för tonåringar?

The aim of our thesis was to gain greater knowledge of how young people relate to religion, religiosity and life, and this behavior might show influences of a gender perspective. Part of the aim was also to have greater awareness of how our education should include a gender perspective. To get to this goal, we have assumed the qualitative investigation method which we discussed with a number of students who read last year of high school. First, the interviews were aimed to let students talk about matters concerning religion and life. The next step was to examine their thoughts with a gender perspective as a starting point.

Hantering av småskalig elproduktion : Utveckling av modell för dokumentation och elkvalitetsberäkningar

The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.

Tidiga insatsers betydelse i lärmiljön : ? en studie av ett elevhälsoprojekt om lärmiljö från ett specialpedagogiskt perspektiv

Early intervention is important on different levels and must be justified as a social and economic long-term investment. There is no doubt about the importance of early detection when helping children/students in need of support. What kind of support that is deemed suitable and who provides the support can be viewed from different perspectives and with different approaches. Seen from a relational perspective the special education process is a long-term process and affects not only the individual but the whole school culture and systems may need changing. This study intends to describe the importance of the learning environment and what efforts are initiated early for students in need of support from the special education point of view.

Orsaker och sammanhang kring avvikelser i processen med prefabricerat byggande

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

Riskmodell för kabelsträckningar i mellanspänningsnätet i Sverige

The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.
