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 analyses the arguments of The Swedish Government Official Report 2008:88 which proposes that the Swedish law (SFS) should shift from promulgation in print to elec-tronic promulgation on a Website. I have studied two aspects of the arguments in the text. On the one hand, the Inquiry?s description of how things might become if their proposal becomes effectuated and, on the other hand, how the present situation is described in the text. The theory I have used is called A Garbage Can Model of Organizational Choice, which pictures organizations as often irrational in dealing with problems, solutions and decision making.

This paper treats George Dickies institutional theory of how to define art. Some alternative theories and their originators are also introduced. According to Dickie something is art because it has been created against a background of an already existing artworld. Dickie has formulated his theory in two different versions, ?the earlier? and ?the later?, which differ somewhat in their design.

The purpose of this study in the psychology of religion is to explore the process of an individual?s shift in orienting system, from a religious to an atheistic. The materials used are autobiographical accounts obtained from two books. One that has been used as a primary source and one as a secondary. By using Rambo?s process oriented theory of religious conversion relevant themes and categories were chosen and later subjected to further analysis using Pargament?s theory of religion and coping.

This paper appeals to professionals working with green questions. It intends to create a discussion about which plant species that can be established in a fieldlayer of a naturelike planting on fertile agricultural land. To initiate the essay, a studie of which values that can be connected with an establishment of a fieldlayer was performed . A part of Tor Nitzelius Park in Alnarp, a so called naturlike planting on fertile agricultural land, was used as a model for the choice of species. With the aid of soil values, photos and a list of current species, interviews with four ecologists were performed.

Syftet med studien är att undersöka huruvida Self-Determination Theory kan appliceras som förklaringsmodell för motivationen hos de anställda på Företaget X. Enligt Self-Determination Theory råder ett samband mellan tillfredsställelsen av basbehoven; autonomi, kompetens och släktskap i arbetsmiljön och motivationstypen hos individen. Tillfredsställelse av basbehoven främjar autonom motivation framför kontrollerad motivation och genererar antingen internalisering av yttre motivation och/eller bibehållande av den inre motivationen. För att undersöka sambandet mellan variablerna genomfördes en enkätundersökning med både anställda i ledande och icke-ledande position. Enkätens resultat visar att basbehoven är tillfredsställda och att motivationstypen är av karaktären inre motivation respektive hög grad av internaliserad motivation.

Citizens? interaction with governments is an area with unique implications for channel management. Governments need to take the citizens perspective into further consideration in order to be successful in delivering high-quality e-services. This paper aims to determine if a categorization of citizen-initiated contacts from a citizen-centric perspective can be a valuable basis for decisions regarding e-service development. The study consisted of three steps.

Public opinion has increasingly become a political force in the European integration process. At present, it appears that the people?s attitude towards the European integration is relatively skeptical. How can we expect that the attitude towards European integration will evolve in the future? This paper tests the extent to which diffusion theory can serve as a model to explain the development of attitudes to European integration policy in Sweden from 1999 until 2009.

AimThe compulsory school attendance in Sweden means that all children are obligated to go to school. This makes great demands on those who work in the school, especially the teachers. Schools are complex units. In school, teachers face all kinds of ethical dilemmas on a daily basis. The aim of the study is to enlighten how different teachers would act differently, if they were facing the same dilemma in the PE-lessons and why this knowledge is important to our profession.MethodThe data was collected through interviews to make a qualitative research.

The aim of this essay is to explore the lived citizenship and its ideal. First, the form and expression of citizenship practice and ideal is explored through a qualitative interwiev study of ten citizens in the southern suburbs of Stockholm. The perception and expectations of the nature of citizenship, presented by the informants, is then compared to their citizen ideal, as well as to the ideal presented and promoted by the Swedish government. The point of departure is theory of democracy. The essay calls attention to an observed lack of empirical studies in the field of deliberative theory of democracy as well as studies that more broadly bring the theory down to empirical earth.

15th of December 2005 was a historical day for the Iraqi people when they could vote for the first time in a free referendum for the draft of the new constitution. The result showed that 79% accepted it. The Iraqi constitution has been criticized by many for its Islamic ascendancy. By giving Islam the role as the source for legislation, will make the situation worse for the Iraqi women, so it has been said.My aim with this Master thesis is not to evaluate weather or not Islam as a religion will undermine women's roll in the society. My ambition is rather to examine the constitution in order to see which kind of theory of citizenship it is inspired from and how will it affect the situation of the Iraqi women.

Crypreservation of oocytes is recently being considered to be a valid choice in infertility treatments.Low survival and fertilization rates due to inefficient slow freeze protocols have been the outcome ofmany previous studies done in the field. However, introduction of the vitrification technique and itsapplication in reproductive medicine and to some extent new improved slow freeze protocols haveshown that oocytes can be cryopreserved with successful outcome.In this project the survival rate of oocytes after vitrification with MediCult Vitrification andWarming Media has been studied. Also, a comparison of the carriers Cryoloop (an open system) andCryopette (a closed system) has been performed.A total of 43 oocytes were vitrified and warmed according to MediCult's protocol, of which 21oocytes with Cryoloop and 22 with Cryopette. The cells were post-thaw incubated in a physiologicalenvironment for 24h. During that time the morphology and viability were observed and noted after 2h,over night and after 24h.

The transformation within the swedish infrastructure has been a slow process from thebeginning of time. For almost a decade, the traditional form of contracting regardingbuildings and foremost infrastructure has evolved contracting involving the owner to definethe outcome of the product, regardless involvement from the supposed contractor. As forthe swedish market, the traditional design-bid-build (DBB) have been the primary choice ofcontracting. Although changes have been made over time regarding contracting formswithin the road administration, the railway sector has not improved or justified changesregarding choice of contracting, they have conducted same contracting relationshipsbetween them and the contractor.This bachelor thesis, conducted at the Swedish railway administration with supervision ofprofessor Kristian Widén at Lunds University, explores the forces behind the new era ofcontracting within the railway administration. This bachelor thesis focuses mainly oncontracting regarding design-build-operate-main (DBOM), the new contracting formulabetween the owner and the contractor.

In this thesis, rare book collections in university libraries are studied. University libraries function primarily as service institutions for students and researchers. Rare book collections may to some extent be seen as a part of this service. Stockholm and Uppsala University Libraries are the focus in this thesis. They participate because of their difference regarding their rare book collections.

On the 1st of November 2010, the statutory audit was abolished for small limited companies. The amendment of the abolished statutory audit includes smaller private limited companies that for two years does not exceed more than one of the two following limits: net revenue of three million kronor, total assets of one and one half million kronor and three employees. The principal rule of chapter 9 section 1 Companies Act remains that a limited company should have at least one auditor. For limited companies included of the amendment has a opportunity to choose bokslutsrapporten instead of the auditor?s report as a proof of quality of the accounting and the financial reporting.
