Preservation of cells and tissues by freezing at temperatures below 70°C has led to new possibilities for the storage of germ cells for fertility preservation. During the freezing process problems might occur, the greatest being ice crystallization which can cause membrane destruction and thus cell death. To minimize this risk, solutions that reduce the freezing point can be added to reduce crystallization and increase survival rates. These solutions are called cryoprotectants. The best method for freezing is still not known.The aim of this study was to analyze the effect of various parameters on the survival rate of human semen frozen with liquid nitrogen.

 This essay is about a little community in Sweden where the identity as a citizen of Vadstena expresses itself in different ways, whether the individual has immigrated or has been living there for generations. It is also about those processes and structures creating an experienced alienation and an equally strong expressive perspective from within. How does the social construct appear to those who want to be integrated, and for those who are supposed to integrate the immigrants?.

This essay inquires with the local authority´s rights versus obligations towards its members in agreement situations, where according to civil law compete with the according to public law.These situations become more and more common, since the public is often integrated in today´s trade and industery. Within this analyses there are statements made by HD about what is the applicable judgement concerning this complex area. HD´s different views and opinions have partly been critizesed by the auther..

Theatre is often seen as an act to entertain or provoke, however the main argument of this paper is that theatre also can be seen as a process to build peace. This study focuses on and explores how artistic processes, such as Forum Theatre developed by Augusto Boal, can be used as a method to promote psychosocial reconciliation in war-shattered areas. With the use of Forum Theatre the spectators becomes the spect-actors, the subjects that act and not the objects that are acted upon. Subjects that are encouraged to try and find solutions to social problems by acting out possible solutions and evaluating them. By analyzing how a number of organizations have worked with Forum Theater on the Balkans and with a theoretical approach combining Homi K.

Information overload is by no means a new concept, but has come to prominence the last decade. A generally accepted definition of the phenomenon does not exist. The main question in this master thesis is how to define information overload in order to create a connotative concept for information science. This thesis reviews the nature and causes of information overload, and considers possible solutions, both individual and technical, and their relevance to the information professional. The review of the results shows that researchers seldom or never give a legible definition of what the concept information holds.

In the low-income countries of the world, rapid urbanization and decaying infrastructure results in an increasingly unsustainable situation when it comes to solid waste management. Often, the solution tends to focus on introducing technical advanced interventions based on the conditions of the high-income world. However, this thesis aims to ?nd site-speci?c solutions on solid waste management at a local scale. By taking in consideration of local conditions a customized approach is possible where the solution is not dependent on expensive structural changes.

Intelligent IT-based solutions, often called Smart Grids, are considered to be the future balancers of renewable energy sources. One area within the Smart Grid concept is called demand response, which is focused on making customers more consumption flexible by making them more active in their consumption. In this thesis the aim is to analyze a business model by investigating the income potential for a demand response solution as well as its market potential. This has been done through literature studies, interviews and development of a computational model.The use of 5000 households with flexible consumption can provide a cost reduction of 17.2% or 2.4 million SEK for a balance responsible party during an average year. If the solution is used to make strategic bids on the regulation markets the study indicates that the largest potential for revenues lies within this strategy.

Sweden is described as one of the most forward-thinking countries in the world when it comes to equal opportunities, yet still management is being dominated by men. Looking at entrepreneurship and gender, the author has written four herstories about female entrepreneurs working, through enterprise, to bring about change to the male domination of top level management. The primary purpose of this master's thesis has been to look at theories on entrepreneurship/ management and gender to analyse how the entrepreneurs relate to their roles as [i] entrepreneurs, [ii] agents of change, and [iii] women. The findings show that they attach particular emphasis to their roles as entrepreneurs. As regards the work for change, being female is described as both advantageous and irrelevant, or insufficient.

In this paper, I have conducted a study of what perspectives educational drama has in theory and practice. The study aims to show an example of how and out of what perspectives educational drama is a part of the school?s activity at a geographically distinct school, from kindergarten on to primary and secondary school years. The general attitude of the faculty and their arguments for and against drama constitute the major aspects of this study, which has been carried out through qualitative interviews at a school in Skåne. The results were that pre-school focuses on teaching drama to develop communicative abilities amongst the students (art educational perspective) while secondary school seemingly abandoned this approach and focuses more on using it for personal development, increasing empathy and understanding of other people by taking it to a more emotional level in order to affect for example moral values of the students.

This thesis was performed at Vendig AB which is a company that develops and sells products such as belt scrapers for conveyor. The thesis is divided into two parts, one part where it´s investigated which tension force is required to tighten Vendig AB´s scraper Hampus against the belt in a correct way. The second part is called mechanical design and here a new and more compact tension device is developed.Field studies has been conducted at a couple of Vendig AB´s costumers to get a knowledge base about how Vendig AB´s products are used, how they function and the environment they operate in. During one of the field studies the force between the scraper and the belt was measured. The result from the measurements, together with a report from LKAB [1], were evaluated and summarized in a table.

The essay is about how immigrant pupils are integrated into the Swedish school and society. I have studied how teachers work with integrating these pupils and if there is a plan of act used in their work. The essay is also about how social relations can be used as a pedagogical resource by the teachers when the institutional framework and support is failing..

The aim of this Master's thesis is to explore how the localisation and the design affect the conditions for a school-media centre. A school-media centre is in this study a place where the students seek, find and evaluate information, discuss and exchange ideas. An active place for generating knowledge. The method applied in this study is "Space Syntax Analysis", a quantitative method with visual representation of the results. In the theoretical framework, space is the voids between walls, doors and ceiling, between furniture and bookshelves.

The transport sector is one of the biggest pollutants in the European Union. In relation to transport policies and environmental policies, intermodal transportation solutions are of high relevance to establish a sustainable transport sector for the future. Intermodality which is defined as smooth transition between transport modes is a key figure for how modal shares are divided between the modes of transportation. The aim of this bachelor?s thesis is to examine the research gap whether policies intended for a specific transport mode affects each other in relation to EU policies intended for intermodality.

Bakgrundsbeskrivning: Traditionellt har risk betraktats som något negativt ocholika typer av risker har hanterats av olika funktioner. Sedan ett antal år har IntegratedRisk Management (IRM) utvecklats som koncept för riskhantering. IRM innebärsamordning och integration av riskhanteringsarbetet. Problemställning: I vissa länder har lagstiftning tvingat företag att implementerasystem som IRM, men det råder fortfarande viss oklarhet i vilka motiven ocheffekterna är. Vi frågar oss därför vilka anledningar det finns att använda IRM? Vad ärmålsättningen och motiven? Vilket värde (effekter) skapar det egentligen för företaget?Vidare saknas det studier i vad IRM innebär i praktiken, särskilt erfarenheter frånnordiska företag.
