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 opinion of social workers towards their work with children and young persons wasstudied in this essay. Even their point of view with reference to the term the child?s bestinterest has being considered and special focus was laid on the social workers attitudestowards media coverage and its criticism towards their work. A qualitative approach was usedconsisted of six interviews. The theoretical frameworks were based on the theory aboutfreedom of action and the theory of social representations.

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.

The purpose of this study has been to get a deeper insight into how students reason about the textbook and teaching that goes beyond its content. This in order for the teacher to be able to consider and respond to these important attitudes already at the planning stages of such teaching situations. This approach will aid to help students overcome the distrust of things that are not in the textbook.The study shows that students have an attitude of overconfidence to the textbook's reliability. It is considered to be controlled in its content as well as being a reference on the extent of the knowledge content.The general approach to teaching that deviates from textbook structure is that it is welcomed as an interesting feature. However, a questioning attitude soon appears about whether the element will be included in any requirements for knowledge or tests.The following important conclusions can be drawn after this study was carried out:Very clearly communicate the purpose of all education that deviate from the textbook.Inform students about the textbook's deficiencies and the need for supplementing.Accept and respond to students' focus in that grades are the main driving force for the acquisition of knowledge in high school..

Studies among parents of children with disabilities have shown that they experience a higher level of parenting stress as well as a lower degree of wellbeing, compared to parents of children without disabilities. However, there is a need to further explore parents? experience on this matter within a Swedish context. The aim of the current study was to examine how parents of preschool children, with and without disabilities, in Västerbotten, experience the impact of their child. A sample of 67 parents of children with disabilities and 134 parents of children without disabilities took part in the questionnaire study.

This paper analyses how Swedish fine-art oil paintings sold at auctions has performed as a monetary investment during the period autumn 1985 until spring 2006. An average price technique as well as a hedonic regression technique, applied to a sample of 19 213 auction sales, is used to construct price indices. The indices show somewhat different results, which is explained by the inability of the average price model to adjust for relative differences in quality between periods. The hedonic regression model on the other hand captures this effect, why the hedonic index is applied in a financial return model. By adjusting for transaction cost, the financial return of an average investment in paintings is calculated.

Background: Parents that loose a child in connection to labour are in great need of support.Health care provider treatment and support is of great importance to how the parents will experience something that is doomed from the beginning to be one of the most tragic events the parents will ever experience. For care givers to live up to this it is incredibly important that there are worked out guidelines to follow at these situations.Aim: To chart and describe Swedish maternity wards care program with reference to ?IUFD?.Method: All clinics in Sweden have been questioned regarding care program for handling of ?IUFD?. Care programs has been gathered, charted and described.Results: 87% (29 of 33) off the maternity wards has a plan for treatment and guidelines for ?IUFD?.

This report treats two assignments that concerns the biofuel furnace at Billerud Skärblacka AB and how these assignments were solved. The assignments were: reducing the number of CO-spikes and tuning the overfire air control loop. To reduce the number of CO-spikes the possibility that skewness in mass distribution affects the number of CO-spikes were study. The skewnwss of mass distribution was controled and adjusted with two experiments. The conclusion that was made is that the skewness of mass distribution were not sufficient enough to affect the number of CO-spikes.

AbstractIn the literature on multiculturalism and group rights there is a strong tradition that sees diversity as something directly paradoxal to unity. In this tradition, scholars put forward a view of multiculturalism as a divisive and exclusionary process which breaks down the cohesion and unity of society. Related to this notion is that of a neutral and universally valid frame of reference in which political dilemmas can be solved; for example a neutral civil sphere where the ?true essence? of society lies. In this essay I attempt to criticise these two notions.

Our study aims to examine whether managers in elderly care are working from a salutogenic approach to create a dignified life for the residents. By this we are trying to find out how you look at life in dignity and what meaning it has, what similarities and what differences there are. We also want to explore what they want to achieve with their work and what they do to enable it. The questions we asked ourselves what the salutogenic approach is for managers working in nursing homes. How do they look at a decent life and we ask ourselves the question of the salutogenic approach is just a "buzzword" in a working man always had or there are real differences? The method we have chosen to use is a web-based questionnaire that we sent to our sample.

The aim of our study was to increase the awareness of the importance of implementation when a policy document is widely introduced. We wanted to examine how a political decision was implemented on different levels in a social care administration. We also wanted to examine the discretion related to the decision on different levels in the organisation, and if the work is followed up. The theoretical frame of reference in our study is Vedung?s implementation model and Lipsky?s theory about street-level bureaucrats.

This study investigates, through parental evaluations, communicativeand adaptive abilities within a group of children with various developmentaldisorders, after the parents had participated in AKKTIV (Augmentative andAlternative Communication ? Early Intervention) parental education. The studyalso investigates through case studies how parents experience the influence ofAKKTIV-intervention in their children?s development a few years aftercompletion. The parents estimated their children?s abilities using three differentquestionnaires; the Swedish Communicative Developmental Inventories(SECDI), Vineland Adaptive Behavior Scales-II (VABS-II) and parts of theform? Parents? perception of the interaction with their child?, before and afterthe intervention.

Sheep have played a very important part in rural history. In Sweden there were many kinds of small native breeds, kept for their meat and fleece. Women cared for the flock that often had very little to feed on during the cold and sometimes harsh winter months. This meant that these sheep over time acquired special phenotypic properties depending on the environment they lived in, and easily fed compared to modern breeds kept for meat. Most of these sheep have since become extinct.

The aim of this thesis is to study the phenomenon of read/write OPAC by looking at how students at Pennsylvania University use PennTags in order to influence document descriptions in the library catalogue. The main questions to be answered are to what extent PennTags is being used in different subject areas and what users contribute to document descriptions through tagging in different subject areas. Studying the posts created by a sample of PennTags users from a quantitative approach I try to find out if there is reason to believe that the activity of users and users? possibility to make meaningful contributions are dependent of the subject matter being dealt with in documents described, as anticipated by the theory of pace layering. I find that user interest in influencing the library catalogue through PennTags appears to be low in general, with exception for in the subject areas of the main classes Language and literature and Social sciences in Library of Congress Classification.
