Värmeväxlare med luftkonditionering för tvättstugor
The energy in laundry rooms, in form heated air, can be utilized with a heat exchanger. A concept and an early prototype of the heat exchanger have already been developed to show that the theory works. This report describes the continued development and construction of the product.A field study was made in order to investigate the environmental usage and establish the product design. The most common washing machine was used as a calculation model, and calculations were also made to estimate the amount of energy in the air. A previous analysis of the existing prototype is also presented in this report, to show the products potential capacity.
Sustainable business practices : a review of eco-efficiency
The current demanding business environment requires corporations to act fast in finding effective solutions to problems given the myriad of challenges they face (Dyllick & Hockerts, 2001). The challenges include the impact of climate change on business practices, natural resource consumption, chemical pollution, technological change etc. Moreover, the forces of globalization, heightened concerns about the deteriorating quality of the physical environment and increased stakeholder power are also increasingly having a real influence on business practices (Rainey, 2008).
Since 1992, the World Business Council for Sustainable Development (WBCSD) has encouraged the adoption of the concept of ecological efficiency (eco-efficiency) to support business efforts aimed at addressing some of these challenges. The aim of eco-efficiency is to reduce the amount of energy and materials used in production processes to achieve economic and environmental benefits (WBCSD, 2000).
Referensarbete 2.0 ? Tjänsten Boka en bibliotekarie på svenska folkbibliotek
This master thesis concerns the subject of a reference service named Book-a-librarian. The service makes it possible for the library-user to indulge in a subject with the help of a librarian after having made an appointment in advance. The main purpose of this thesis is to study the function of it. The methods used are a mix of literature and empirical studies to be able to comprehend and explain the practical nature of the service as well as placing the service in a theoretical framework. The empirical study is performed by a questionnaire, where librarians working with the service are asked to participate.
Organizing for value creation : a corporate perspective on urban farming
In the year 1800, about 5 % of the world population lived in cities (World Wide Fund for Nature, 2012, 3). Today that number is about 70 % in Europe and North America, and in 2050 it is expected to be 86 % in the developed world and 67 % in the developing world (www, UN, 2009). In addition, the global population is expected to increase with 2.2 billion people until 2050. As a result of the population increase more food has to be produced which requires more transport from the countryside to the cities. However, this flow of resources faces some difficulties.
Ungdomar om bibliotek
The aim of the thesis is to study young peoples, defined as boys and girls between 14 and 16 years old, attitudes to library in two municipalities. Notwithstanding the fact that young people, and children, often is given priority in library work, the reality often seems to be another. Attitudes are founded primarily in childhood and therefore it is of great importance to examine how young people regard libraries. Besides studying former research about young people and libraries that has been performed on library and information science, we also have been using concepts and theories from social science. We give a brief outline of youth research and its development and look at official records and legislation to see if and in what context young people are mentioned.
Interaktion med surfplatta och traditionella leksaker inom förskolan : En studie av likheter och skillnader ur ett socialt- och lärandeperspektiv
The main purpose of this study is to examine differences and similarities concerning teamwork and interactive skills among preschool children while they interact with an Ipad respective a number of selected traditional artifacts. The traditional artifacts chosen for this study are small Lego blocks, JovoToys (click and construct system) and large puzzles. The study takes its starting point on the basis of both a social- and a learning perspective when different groups of preschool children in the ages from three to five years interact in fellowship groups with respective artifact. Primarily the main focus is to examine differences and similarities that appear from without the social perspective.The overall objective is to identify what eventual differences and similarities can be found purposely on both what is happening in the social interaction between the preschool children themselves but also what is taking place in the interaction between the children and each artifact. This study will also via theoretical frameworks create an understanding why eventual differences and similarities exist.The results are based on both a literature review and a field study.
Skolan, en viktig del i ensamkommande flyktingbarns socialisation
AbstractThe purpose of our study is to reach an understanding of the situation of unaccompanied refugee minors in school. Thus the study aims to investigate what sort of possibilities and limits they encounter when going through their school education. We have chosen a qualitative method and conducted interviews with four persons between the ages of 18 and 21 years.The result of the study shows that unaccompanied refugee minors experience numerous limitations and lesser possibilities than other students, which prevents their educational and social development. The limitations partly depend on the school personnels lack of knowledge about this target group, and partly on the difficulty of dealing with a new culture which is different from the students original culture. An important conclusion that our study has shown is that the educational system has a great impact on how well the students manage to function in the new society later on. Therefore it is of great importance that the teachers have access to competence development , since this is of substantial importance for the unaccompanied refugee minors development and socialization. .

Utveckling av biopsiinstrument : Instrumenthållare för skruvnålsbiopsi
This Master Thesis has been carried out in cooperation with Ursus Medical AB (URSUS) which markets, assembles and sells the Rotex Screw Needle Biopsy Instrument ®. The instrument is delivered with an instrument holder. Customers had expressed dissatisfaction over that they needed to use two hands during a biopsy procedure, which resulted in a project to develop a new instrument holder.The project aim was to create concepts for how the new instrument holder should be designed, with focus on the mechanics. The new instrument holder would build on the existing basic principle that the screw needle and the cannula were screwed into the tissue. The thesis work would result in a technical solution and a functional prototype of the chosen concept.To achieve this, a generic product development processes were used and began with a comprehensive literature review.

Evidens som hegemonisk strategi i socialt arbete : en diskursanalys av den språkliga praktiken i en barn och ungdomsgrupp som arbetar med ett strukturerat beslutsstöd
This thesis describes how social work language practice circulates around the implementation process of an evidence based structured assessment tool – Savry. The purpose is to examine and understand the social workers language practice in a working group that uses this structured assessment tool in their work with youth. The purpose is also to look for dimensions of identity in terms of discourse. The ontological viewpoint is post-structuralism where language is in focus. The theoretical framework is discourse theory based upon the work of Ernesto Laclau and Chantal Mouffe.
Kalkylarbete för byggnadsprojekt med Vico Office : För- och nackdelar med 5D BIM
AbstractBuilding Information Model/Modeling/Management (BIM) is a tool that allows for efficient working methods. BIM saves time and money while providing the potential for visualization. This method of working is based on a 3D-model, and then a fourth and fifth dimension are connected. 5D modeling means that a spreadsheet creates cost estimates based on the 3D model. This provides opportunities to carry out calculations in the early stages of the projects. Calculations are currently performed manually and do not contribute to the development that the construction industry requires.
