Kylbehovet hos ett batteribaserat elenergilager : Med avseende på kyldistribution, drifttemperatur, klimat, isolering och termisk tröghet
Under 2011 började MacBat AB ta fram ett elenergilager kallat Macbat Energy Storage System (MESS), vilket är uppbyggt av 360 stycken tvåvolts bly-syrabatterier inhysta i ett 20 fots container. Då bly-syrabatterier är känsliga för värme är den här studien inriktad på att utreda hur stort kylbehovet blir under olika förutsättningar där kyldistribution, drifttemperatur på batterierna, klimat, isolering och termiska tröghet är varierande parameterar. Det ska även avgöras vilken konfiguration av kyldistribution och isolering som ger lägst kylbehov för de studerade klimaten, vilka är av varmtempererad, arid och tropisk karaktär.För att besvara studiens två mål togs fyra matematiska modeller fram i SIMULINK. Två luftkylda och två vattenkylda där en av varje var isolerad med 100 mm mineralull medan den andra var oisolerad. För samtliga modeller varierades drifttemperaturen mellan 25 ? 35 °C och de studerade klimaten utgjordes av Phnom Phen, Kambodja, Djibouti, Djibouti, Bagdad, Irak samt London, England.
Barn och stress : En studie om fritidspedagogers erfarenheter kring stressade barn på fritidshem
The study aims to contribute knowledge about children's perceptions of the leisure-time as a learning environment. The study can be seen as an attempt to highlight the possible learning in the leisure-time, formally or informally.The study is based on two group interviews with a total of 11 children and was conducted by an interview guide with question areas to be discussed freely so that the children could give as full an answer as possible.Main results of the study show that children feel that they are staying at the leisure-time to get care when their parents are working and that they primarily associate the leisure-time with playing. The results show however that children feel that they learn things when participating in the leisure-time teaches controlled activities.It is possible to draw conclusions about the child actually experienced the leisure-time as a learning environment, but it can be difficult to identify when and how learning actually occurs. However, children do not perceive that there is learning while they play..

Fruktosamin som markör för diabetes mellitus hos katt :
Diabetes mellitus is characterised by persistent hyperglycemia in all species. Fructosamine is a glycated protein reflecting blood glucose concentration during the preceding weeks. It has become a valuable analysis to differentiate persistent hyperglycemia from transient stress induced hyperglycemia in cats. It is also used to evaluate current therapy in diabetic patients. Although fructosamine is a well accepted analysis, it is sometimes regarded with scepticism.
Inventering och bedömning av förorenade områden inom division Energi, Tekniska Verken i Linköping
This thesis was commissioned by Tekniska verken, Energy Division with the overall aim to investigate the concept of environmental debt and what it means for a business. Furthermore, a sustainable risk and responsibility investigation shall be carried out on the concerned areas. Finally, the priority areas shall be highlighted and proposed actions presented. The Swedish Environmental debt concept was presented in 1992 by Arne Jarnelöv. Environmental debt is defined as restoration costs for environmental damage. In the early days the concept did not take into account who was responsible, but the environmental debts was regarded as a humanity debt to future generations.
Time & Sväng i sång
Syftet med studien är att få djupare insikt i sångpedagogers syn på Time och Sväng samt hur de didaktiskt arbetar med dessa aspekter. Det saknas mer omfattande forskning inom området. Med detta i behåll har jag för avsikt att få djupare insikt i frågeställningar som rör olika förhållningssätt till hur sångare kan öva upp Time och Sväng samt vad Time och Sväng innebär, generellt och i ett undervisningsperspektiv. Studien har som sin teoretiska utgångspunkt ett sociokulturellt perspektiv med fokus på hur människor använder olika redskap för att kommunicera med sin omgivning.För att få svar på mina frågor har använt mig av en halvstrukturerad intervjuform när jag samtalat med informanterna. Alla informanter i denna studie arbetar idag som sångpedagoger; två av dessa är mer inriktade på jazz medan de andra två är mer inriktade på populärmusik.

Tidlös ensembleundervisning? : En kvalitativ studie om hur pedagoger undervisar Time i ensemble
Syftet med studien var att få en djupare inblick i hur ensemblepedagoger ser på Time samt hur de didaktiskt arbetade med detta. Vi avsåg att få djupare inblick i olika förhållningssätt som ensemblepedagoger kan ha till Time i en undervisningssituation, samt vad begreppet Time innebär. Studien har sin teoretiska utgångspunkt i ett sociokulturellt perspektiv med fokus på hur människor använder olika redskap för att kommunicera med sin omgivning.Vi anser att vi har fått en bredare ingång i ämnet genom att alla pedagoger spelar olika instrument. Den gemensamma faktorn är att de undervisar i ensemble på folkhögskola. I undersökningen använder vi oss av den kvalitativa forskningsintervjun för att söka svar på våra frågor.
Ledtidsanalys på Peltor AB med logisk gruppindelning på elektronikprodukter
This report is the result of a case study at Peltor AB during the spring semester of 2007. The task Peltor gave us was to improve the delivery accuracy and to lower the high finical value of delayed orders (backorder), and to divide the products into logical groups. The logical group will be a useful tool to remain a high level of service. If the level of service increases the company will be more competitive.The electronic department at Peltor has problems with delayed orders. According to Peltor, the problem is based on delivery lead time which is presumed.To increase the delivery accuracy, a lead time analysis is made to find the accumulated delivery lead times for each product.

Pedagogisk samling i förskolan : En kvalitativ studie om förskollärarnas tankar kring samlingens betydelse för barns språkliga och sociala utveckling
The purpose of this study is to examine how pre-school teachers think about the importance of circle time in regard to the child's language and social development from a sociocultural perspective. Furthermore the study will include what role the educators? have during the circle time.To answer our purpose we have chosen the following question:What is the role of the teachers in the circle time?What are the teacher?s thoughts about the circle time?s importance to children's social development?What are the teacher?s thoughts about the circle time?s importance to children's language development?The study is constructed on qualitative methods, where we conducted structured interviews with six preschool teachers and observed their circle time to collect our empirical material. The study is also based on Vygotsky's sociocultural perspective which says that all learning takes place through relations and interaction with other people in the cultural context you are in. The results have shown that pre-school teachers are aware of the circle time?s importance to children?s development, and purposely plan the circle time to give children the opportunity to develop both socially and linguistically skills..
Urskogen med de stämpelbleckade gammeltallarna : en skogshistorisk tolkning av Brännlidens naturreservat
People have used forest resources in northern Sweden for different purposes. Before the 20th century the forest was used for many different reasons, but during the past 200 years it has become an industrial raw material. The presence of people in the forest has left different kinds of traces in the forests. One example is culturally modified trees (CMT´s). The aim of this study was to study and document how people have used the forest resources during the last centuries in Brännlidens nature reserve, and what kind of traces this land use has left.
