Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

Background: The environment and the design of auditing regulation can vary significantly between countries, which can affect the form, content and quality of the audit report. The purpose of the International Standards on Auditing, ISA, is to facilitate the work for auditors on an international basis. Sweden today follows the RS 600 which is based on ISA 600, which contains standards for when an auditor use work performed by other auditor. In October 2007, came a revised and redrafted version of ISA 600 that will be enforced in Sweden in the audit of the financial year beginning on 1 January 2011. To what degree the new requirements will affect the group audit is clearly dependent on how the reporting, evaluation and instructions between the group auditor and other auditor has been carried out previously.Aim: The aim with this paper is to explain the reporting between the group auditor and other auditor in an international corporate group.

The purpose is to increase awareness of the importance of staff engagement in the work environment and how the organization works to engage employees to want to participate actively in the work environment.The questions we seek answers to in this study is the following:What affects the staff to engage in the work environment from a managementperspectiveAre there external factors that affect the organization and the individual's engagementto work with the working environment?We have create a model that is based on recent research to define our definition of engagement. The model contains four factors : Clarity, Advocacy opportunities, resources and feedback. The method we have used to answer the purpose in this study is ten qualitative interviews with persons with work environment responsibilities.The result shows that the engagement regarding work environment is important to get the employees to actively participate. To get the engagement from the employees the organizations need to provide, clarrity, advocacy opportunities, resources and give mutual feedback.

Today automotive manufacturers are facing a crisis with increased pressure to strengthen their brands. To prevent declining results many automakers have chosen to extend its brand to other industries i.e. various forms of brand extensions. Automotive manufacturers have developed an international strategy for what merchandise to offer. The strategy has received an overall positive response, however, it does not apply well within the Swedish market where merchandise is sold in less quantity than abroad.

Aim:In this study, women were interviewed about their experiences of recovering from an eating disorder - The aim has been to investigate the factors that contributed to recovery and with guidance of these factors, find factors that can be used in a preventive intervention.Method: A qualitative approach was used to design and conduct interviews, the design of the study was descriptive and a semistructured interview was used. The local affiliation of The Swedish Eating Disorder Association was contacted and provided contact with 10 women who participated in the interview. To participate in the study the women had to be recovered from their eating disorder for at least two years. The women who patricipated in the study were between 22 and 36 years old and had been recovered for 2- 16 years. Data were analyzed and coded then categories with similar themes about the factors that were important for recovery wad etablished.

The study proceeds from a phenomenom called co-creation. If value can be created, it is logic to asume that it also can be destroyed. This phenomenom has earlier not been applied to long-term relationships such as business to business. In a business relationship it is important to identify factors, that leads to co-destruction, to be able to prevent them from appering. The purpose of this study is to identify which factors leads towards co-destruction.The study have used theories from Echeverri & Skålén (2011) which has designed a model explaning the outcome of co-creation and co-destruction.

Deregulation on the market for agricultural products leads to a more globalised market with increasing price fluctuations. This, in turn, places the farmer in positions influenced by new risks but also improved opportunities. The farmers are faced by uncertainty in terms of financial outcome. To be able to utilise these new market conditions it becomes increasingly important for farmers to continuously follow the price trend, and to develop strategies how to manage the risks exposed by a volatile market. Farmers with different conditions perceive risk in different ways. Hence, their risk management behaviour will vary.

Syfte: Studiens syfte är att analysera hur flygbolaget Ryanair prissätter sina flygbiljetter och om det skiljer sig beroende på flygsträcka.Metod: En kvalitativ longitudinell studie med deduktiv ansats där primärdata i form av prisuppgifter samlats in från Ryanairs hemsida.Teorier: Prisdiskriminering, Priselasticitetshävstång, Operationell hävstång och Hallbergs prisstrategier.Slutsats: Studiens resultat bekräftar Anjos, Chengs och Curries teori om att lågprisflygbiljetter håller sig på en ganska stabil nivå fram till att det återstår ungefär 20 dagar kvar till avresa, då priset stiger fram till avgångsdagen då det är som högst. Detta motsäger Anderson och Wilsons teori om att biljettpriset går i cykler och att flygbiljetterna är som dyrast några dagar före avresa för att sedan sjunka i pris. Den höga prishöjningen på avgångsdagen sker konsekvent på alla de undersökta flygsträckorna och är intressant eftersom höga priser inte är något som lågprisflygbolagen vill förknippas med. Förklaringen kan vara det som diskuteras av Piga och Bachis om att flygbolagen försöker skapa en osäkerhet hos resenärer kring när det är billigast att köpa sina flygbiljetter. Studien resultat visar också på att det går att se ett mönster i prissättningen av flygbiljetter på Ryanairs resmål med få flygningar medan de mer populära resmålen har en mer dynamisk prissättning som är desto svårare att förutspå..

Automatic milking systems (AMS) provide the opportunity for less manual labour and an increased milking frequency. But in order to reach an optimal milking frequency a well-functioning cow traffic is crucial. There are many factors affecting cow traffic but one factor that has not been studied thoroughly yet is the effect of different light intensities during the night, 22.00 h to 05.00 h. Therefore the aim of this study was to determine the effect of different light intensities during the night on number of selection gate passages (GP), milking frequency and milk yield. The study was conducted as a Latin square were three light intensities were applied: LOW (11 ± 3 lux), INT (33 ± 1 lux) and HIGH (74 ± 6 lux), in three different herds.
