This degree project handles acoustic measurements of the heat pump EcoAir 107, made by Enertech CTC AB. The sound from the three sound sources of the heat pump, fan, compressor and four way valve, have been measured to find out how they affect the total sound level of the product.Measures to attenuate the sound level have been developed and tested. By comparing these with the sound of the heat pump, in its original state, we have found out the measures which have best effects.The best attenuating measures came to be: taped openings and holes around the compressor space, isolating the top and the bottom of the whole construction, support of the fan bottom part and shielding of the sound source with a screen at a distance of 110 mmThese measures have been tested together and an average attenuation of the total sound level with 3,9 dB have been accomplished. In the front of the fan where the continuous sound is the strongest, the attenuation was 4,7 dB.This project is meant to be used as a guide by Enertech CTC AB:s during their future developing process..

AbstractSweden has over the past years grown into a multicultural society which has caused that people with numerous variances of religion and cultures have to interact. This essay will be based on several primary school teacher?s experiences with immigrant families. The purpose of this essay is finding out how they are introduced and integrated in Swedish primary schools by the teachers.I?ve interviewed six primary teachers that shared what they?ve experienced with immigrant families.

The aim of this thesis is to investigate how municipalities handle planning of megaprojects. The term megaproject here refers to a large project in terms of time, space, investments, numbers of agents etc. With an increasing importance of the phenomena the need of discussing the role local politics could take in this process is important.How do municipalities handle the difficulties that come with megaprojects and what roles do they take in their work with megaprojects? These empirical questions are tested on a case where the municipality of Lund works with the megaproject European Spallation Source (ESS). A theoretical question discusses the megaproject in the light of governance and government, and structures the analysis around these two important terms.Different parts of the municipality handle there part of the planning from there own logic.

The purpose of this study was to find out what pedagogues in preschool think when it comes to children?s influence and how they do to give the children opportunity to express their thoughts and point of views and thereby influence their situation.The literature review treats the conception of the competent child and shows that having child perspective is important in meeting children. The literature review implies that participation and influence means sensitivity to children?s expressions and that pedagogues lets these expressions influence the activities in preschool. It is not about children always getting their ways, but that they are respected and are given space to think freely.Searching for pedagogues? thoughts on children?s influence and how they do for giving it, I interviewed six persons, working at six different preschools.

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

The sound part is mainly practical and is dependent on concepts that have been tested through measuring with a sound level meter. The design part is more theoretical and has been verified with CAD models and finite element analysis.With a sound damping hood on the compressor the sound level is reduced with up to four dB. An optimized absorbent for the compressor space gives a reduction with three dB. By using the insulation for the heat water tank as absorbent we can see a sound reduction on the lover octave bands. A reduction like this is elsewhere hard to achieve as at it requires thick absorbents.By changing the today?s insulation to the heat water tank to a form of polystyrene polymer insulation the weight from the heat pump above can be transferred to the stable heat water tank.

The aim of this study was to examine how sports journalists used religious metaphors when covering football during the time span of the study, and how the athletes were portrayed as a result of the usage. The aim was also to study if the usage differed between the two newspapers chosen for the study, one of which is a morning paper (Dagens Nyheters sport section) and one which is an evening paper (Sportbladet).To answer our questions we used a quantitative and a qualitative method, the later of the two was based on a metaphor analysis. The quantitative method consisted of a content analysis where different variables were examined. The time span of the study is articles from one year.The results show that the religious metaphors were used in many ways. Some religious metaphors, such as ones including the word miracle, were more prominent than others.

Bostadsbristen för unga växer i takt med att fler byggherrar avstår från att bygga små lägenheter, då rådande lagar gör det svårt att på ett gynnsamt sätt producera kostnads- och yteffektiva bostäder. Bostäder har i dag krav på sig från kommuner och beställare att uppfylla svensk standard. Däri har handikapporganisationer drivit fram tillgänglighetskrav som medför att alla nyproducerade bostäder är tillgänglighetsanpassade.Genom att ifrågasätta svensk funktionshinderspolitik i samband med bostadsbyggande har detta examensarbete som mål att hitta lösningar för att öka nyproduktionen av små bostäder. Granskningen resulterade i ett förslag till en ny standard för ungdoms- och studentbostäder vilken underlättar vid projektering av mindre enskilda bostadslägenheter..

Syftet med denna studie är att beskriva, analysera samt diskutera kommunikation och interaktion i den förskoledidaktiska verksamheten utifrån ett sociokulturellt lärande med utgångspunkt i lek. Under våra besök på förskolan så valde vi att använda oss av videoobservationer men även ta hjälp av fältanteckningar. Denna metod hjälper oss att få en djupare syn på kommunikationen samt interaktionen mellan barn-barn men också mellan pedagog-barn. Under tiden vi utförde dessa observationer så utförde vi detta genom att vara icke ? deltagande för att inte kunna påverka deltagarna.

The purpose of this essay is to examine progression in user education atprimary and secondary school levels, specifically the role played byschool libraries, librarians and strategy documents in securingeducational progression. Progression is examined in the user educationprovided by the five schools, part of the same municipal schoolmanagement area which share the same strategy plan. The area, NorraFäladen, was awarded School Library of the Year in 2011 for its work,making it particularly interesting for this essay's purpose. The studycombines interviews with the area's three school librarians, who dividetheir time between the five schools, with an analysis of the strategydocuments that regulate user education within Norra Fäladen. Theanalytical framework is based on: AASL's model of progression in usereducation (Standards for the 21st-century learner); Ekström's model forsuccessful and active strategy documents; Kuhlthau's theory of thelibrarian's role in the information search process; and Limberg'staxonomy of the role of the school library.The study shows how a number of concurrent factors and prerequisitesinfluence how goals for progression in user education are met.

The purpose of my study is to describe how educators think about the play environment, the nature and its importance for the children's development and learning in preschool. The study is based on qualitative interviews with four active educators. The results of the study show that the teachers regarded the children's interests to a great extent when the different play environments were structured. They are also based on different themes that they have seen that the children were interested in, such as the fire station, hair salon or shop and café. Educators designing not only these play areas for different types of play for the children, but the different environments also have a learning purpose. The outdoor environment however attracts greater interest from children, to where they have more space to move freely in and outdoors, there are no limits to the children.

The sun is a huge energy source with great potential of providing energy to the heating of homes and other buildings in an environmentally sustainable manner. In order to provide buildings with energy from the sun it is necessary to transfer the energy supply over time to when the demand arises. By storing the heat in a seasonal storage, solar energy from the summer can be used in the winter when the demand for heating is greatest.Today's existing plants are mainly in Europe and particularly in Germany. These facilities are designed to supply heat demands greater than 400 MWh and covers about 40-50 % of this need which consists of energy for space heating and domestic hot water. How much of the heat demand that is covered, the solar fraction, is partly due to losses from the storage which in turn is connected to the surface area of the storage.

Several studies show that the clinical reality in psychiatric care does not correspond to the demand of consumer participation from a variety of policy documents that has been produced recently. Studies also show that there is a lot to do in improving, patients with sever mental illness, becoming more involved in their own care. The nurse has a central role in this work. The Norwegian nursing theorist Jan-Ka?re Hummelvolls holistic, existentialistic model for psychiatric nursing were used as theoretical ground.The aim of this study was to examine how nurses in psychiatric outpatient units, caring for patients with psychotic disorders, experiences consumer participation.Qualitative phenomenological method was used.

The aim of this thesis is to investigate how students in higher education use talking books. This has been inves-tigated through qualitative interviews with nine students. The intention has been to find out how they use talk-ing books and why they have chosen to do it in the way they have, looking specifically on whether there are strategies shared by most of the interviewees.As a theoretical basis of the thesis I have chosen a study, described by Sigrid Hongset, where dyslectic pu-pils tried using printed text and text on tape, as well as both simultaneously. George Kingsley Zipfs ?Principle of least effort? will act as a supplemental theory.The interviews show that the students use talking books in different ways.

The role distribution between designers and product coordinators and the system support between these roles are adapted according to the method of working that product models primarily are created for production and after sales market. At the same time models are also created to support a cross-functional way of working. This means that product structures exists on paper and as CAD-models before they are created in Scanias PDM-system environment which leads to unnecessary work and to information not being shared as early as it should be possible.A theoretical study has been performed with the purpose of understanding the problems and to create a foundation for improvement suggestions. Representatives from both roles have been interviewed together with other individuals with insight in the collaboration. A minor study concerning the roles of interests? collaboration at Volvo CC was also performed to be able to relate the study to another company.
