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.

The aim of this Masters thesis is to examine how five childrens librarians in Ireland and five in Sweden interpret and implement the United Nations Convention on the Rights of the Child in public libraries. This study is hermeneutic. Using a qualitative method consisting of ten interviews with childrens librarians and structural factors such as; library policies and laws; together with an insight into Irelands political, social and economical history and the historical development of childrens public libraries in Sweden and Ireland, has enabled us to create an understanding for the interviewees statements. Anthony Giddens structuration theory has been used for the analysis, helping us to determine how the duality between the structure, the actors and their action effect the interpretation and implementation of the Convention in librarian work. The result of the analysis clearly shows that in Comparison to Irish librarians, the Swedish interviewees are more aware and have a better understanding of the Convention and how to put it into practice.

This essay discusses the issue of the role of women and also whether they could obtain a strong social position during the Viking Age. Moreover, it does discuss the question of how frequent women were present in Viking Age scriptures, art and archaeological artefacts in Comparison to our view of women and her position in the modern society. The archaeological material used is in majority that found in Birka, such as burial and habitational findings. These objects, as well as other comparable and similar findings from other places, when put together with written sources, show that women had different roles in the society. She was able to have a strong social role during the Viking Age not only becauseof the status her family had but also because of her own merit depending of her skills and ability.The archaeological findings found in female graves and other findings in the area, suggest a specializing within both textile production and trade for the women.

The goal of this thesis is to analyse whether the method ?Observiaire? is of any use for traffic analysis. The method consists of analysing film material, preferably before and after changes are made to an area, by answering a survey for the users that are observed within the population. The method also opens up for deeper qualitative analyses which are rooted in the quantitative data collected from the survey-study. In this study we analyse the method by applying it to the case study of the changes made at Götgatan in Stockholm, where a green wave was implemented and the bicycle road widened.

The aim with this report is to formulate a strategic method to optimize selection processes of DNA-samples from a faeces inventory to identify as many individuals in as few analyzes as possible, and by that keep down the costs of brown bear management. Brown bear management in Sweden founds today on results from faeces inventory and is substantially led by the county administration boards. Data from the years of 2004 and 2009´s inventories in Västerbotten was used to test and evaluate different methods in selection processes of which faeces that should be sampled. Comparison were made between making selection by chance, by spatial distribution and by calculating variations in logistic regressions coefficient b, in other words bear density and probability in finding same individual in several faeces. We can show making selection by chance is the most uncertain method.

This report covers the thesis done by mechanical engineering at the engineering program at the University of Halmstad. Student Work Development of packaging in the food industry includes 15 credits and has performed over 20 weeks in spring 2009.

When salt is one of the world's cheapest commodity was packing all the costs have to be as low as possible.

The purpose of this Master?s thesis is to describe the development of the most important libraries in Skövde, starting from 1830. We conclude our examination about 1940, when the municipal library has been active for almost ten years, and the libraries started by the temperance and working-class movements have been deposited at the municipal library. In order to explain this process we describe the development of the Swedish public library and its predecessors, such as reading societies and the popular national movements? libraries, as a background and Comparison to the early libraries in Skövde.

The aim of this study is to evaluate whether the working model, presented by The Swedish Floorball Federation, has been a good method to work with gender equality within Swedish floorball associations. The purpose of the The Swedish Floorball Federation?sproject was for its associations to develop a plan of action for how to act to be an equal treatment association pursuing an equal treatment sport. 13 associations answered the questionnaire study. The result show that the great majority clearly found a need of change to become more equally treating and most of those associations have somewhat of an idea how to realize those changes.

This study is a thorough Comparison between what people think about the website www.sl.se, which is a Swedish web-based travel planner for Stockholm metropolitan public transport (such as subways, busses and suburban trains), and how these views compares to the design of the actual website itself. The travel planner offers a wide range of functions and services for their targeted audience to find the fastest route between their current location and their destination. These functions are for example real time information on hold ups and malfunctions on different travel routes, and an interactive map of specific destinations so that the user can get a clear view of the area and nearby traffic stops. But how much does the average user care for these functions, and how often are they used on an average visit? What are the users? motivations when they visit the site? Earlier research suggested that there are services and functions on this website that are useful and well crafted, but that some people may not be aware of.

This is a qualitative study based on eight interviews, four of which have been probation inspectors and three have been external controllers, or controllers as they say, and one have been an email interview with the headquarters of the correctional treatment. The interviews have been made on probation service offices in southern Sweden.The purpose of this study is to investigate how the professionals in Probation service see their work with intensive supervision with electronic monitoring. We are interested in their work from mainly three aspects, how they look at their control, how they see the intensive supervision with electronic monitoring as collective punishment and how they work with the client's family.In our results it emerges through interviews that probation staff in general find it difficult to work with the Children Convention (CRC) and the law when it comes to intensive supervision with electronic monitoring. They mostly do not believe that intensive supervision with electronic monitoring is a collective punishment for the adults but when it comes to children it becomes a longer discussion with different arguments and thoughts.Our results have found that in Comparison to prison, most people seem to find that intensive supervision with electronic monitoring is a decent punishment. Most of the professionals are aware, and think it's important to recognize, that they are in a position of power in relation to the client.In the analysis, we establish an outcome from the interviews into our theories and trying to find a connection between them..

This essay is essentially an analytical Comparison of economic and democratic values. The purpose of this is to understand whether or not a conflictof values is in effect, given that democratic values have been expressed as highly desirable and in need of reinforcement while simultaneously economic values in the shape of New Public Management enjoy widespread acceptance andimplementation.Denna text utgör ett försök att ställa demokratiska och ekonomiska värden mot varandra för att se om värdekonflikt föreligger i en situation då demokratiska värden uttryckts som önskvärda och i behov av förstärkning och där New PublicManagement, ett reformprogram som i grunden utgör ett försök att införa mekanismer för styrning och organisation som byggts på marknadsekonomiska värderingsprinciper i stor omfattning genomdrivits inom offentlig sektor. I texten förs ett resonemang som når fram till slutsatsen att en värdekonflikt faktiskt på sätt och vis kan sägas föreligga mellan demokratiska och ekonomiska värdena om ekonomisk effektivitet inom offentlig sektor behandlas mindre som ett medel för demokrati, än som ett mål i sig självt. Frågan visar sig i slutändan handla om användandet av en ny normativ logik som inte är fullt kompatibla med den kontext den försöks infogas i..

AbstractIntroduction: Hand Arm Risk Assessment Method (HARM) is a tool to assess the risks of deve­lo­ping complaints of the arm, neck or shoulders during manual work. The method was developed in the Netherlands primarily for employers, but is also used as an aid to work environment in­spec­tors. The purpose of this study was to evaluate the HARM-method for assessment of biomecha­nical exposure of the upper limbs when performing manual tasks as well as its suitability to be used within work environment inspection. Methods: Ten labour inspectors conducted assessments of five video-recorded work tasks. Assess­ments made with HARM were compared with those made with the Assessment of Re­pe­titive Tasks (ART) tool and with ACGIH Hand Actvity Level (HAL) - both methods for assess­ment of bio­mecha­nical exposure of the upper limbs - and with the model for the assessment of re­pe­titive work in the pro­visions of the Swedish Work Environ­ment Autho­rity on ergonomics for the prevention of mus­culo­skeletal disorders, AFS 1998:1.

Background: As a part of a national health control program, Statens VeterinärmedicinskaAnstalt performs diagnostics to screen flocks for certain pathogens causing high mortality,morbidity and/or serious economical losses. There are several viruses in the programincluding IBDV (infectious bursal disease virus), IBV (infectious bronchitis virus) and NDV(Newcastle disease virus). Method: 96 serum samples were collected from different poultryflocks in Sweden and analyzed by ELISA, which are currently used in the health controlprogram as well as by a commercial prototype of a multiplex immunoassay manufactured byLuminex Corp., which is currently under evaluation at the United States Department ofAgriculture USDA. This 4-plex assay detects antibodies for the three above-mentionedviruses as well as antibodies of avian reovirus. In the context of this study the ELISAs run inroutine diagnostics as well as a REO ELISA were used as the standard for Comparison.Result: The antibody concentration in serum from vaccinated chickens was high while theantibody concentration level in serum from not vaccinated chickens was low.
