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 focuses on the implementation of the strategy gender mainstreaming in the European Union and the member states. It starts to identify problems connected to the implementation process and recognizes significant prerequisites for an efficient implementation of the strategy. The main problems and prerequisites are: political will, governance and structure and knowledge about gender equality. The empirical material consists of reports from the EU that touches upon gender mainstreaming and gender equality. The problems and prerequisites will be analysed in relation to the governance perspectives top-down and bottom-up and expert bureaucratic and participative democratic and gender and feminism.

Using leaching test is a way to get a picture of pollutants retention and leaching in a risk assessment on contaminated land. There are several different types of standardised leaching tests today, where the natural leaching processes are speeded up to make it possible to predict the leaching of pollutants. These leaching tests have been developed for waste and there are no specific guidelines on how to judge the results from the tests, when making a risk assessment on contaminated land. This work is an investigation on how to use leaching test in this type of risk assessments. The strengths and weaknesses of the different types of tests are discussed. Depending on what type of information you want from your leaching test, different types of tests are suitable.

The origin of the word ?communication? is the Latin word communicare, meaning to make common. The reason for our communication is to share thoughts, feelings and information, we want to affect and confirm.We are used to interpersonal communication, but even if we have had a lot of practice at it during our lives, we still find our selves facing misunderstandings and conflicts. The more people we meet during a day, the greater the chance is for interruptions in the communication.In pharmacy practice, good communication is vital for the client?s health and quality of life.

This study will examine if caregivers, working with people with dementia problems, is in need of support and in what way they see how the support should be designed. Previous research shows that there are many factors in elderly care that affect all of the caregivers. Working with people in this sort if dependence, requires a lot of the caregivers, both mentally and physically. To study if the caregivers consider themselves to be in need of support, and in what way they see how the support should be designed, the study employs a qualitative approach using to types of interviews, one focus group with four assistant nurses, and two individual in-depth interviews with the administrative personnel and one nurse. The results show that the need for support for the caregivers exists. Caregivers working with people with dementia problems, daily face difficulties, some more difficult to handle than others.

The river Bivaröd is one of the river Helgeån tributaries which has the highest and the fastest increase in water colour. The reason behind this increase is unclear but several factors have been suggested to affect this pattern. In this work, I studied the role of land use, iron and precipitation for water colour increase in river Bivaröd for the period 1976 -2011. Data from a field study along with data from SRK for river Helgeån were used for the analyses. The results showed that both water colour and iron concentration increase and that there is a strong correlation between these two variables.

This essay is about children who have psychological and social problems. An increase part of children and young people in Sweden describe this kind of difficulties. These problems are at the same time a concern for the school as well as the social welfare. The purpose in this essay is to explore if children with psychological and social problems have the same legal rights to education as other children. The main questions are to describe the legal rights in this area and explore how schools and social welfare cooperate in order to achieve better possibilities for the children.The facts take a legal aspect as a starting point.

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

Chemical substances are spread diffusely and uncontrollably as a result of the increased consumption of goods. REVAQ is a certification system that works to reduce the flow of hazardous substances to Swedish treatment plants and to create a sustainable nutrient recycling. According to REVAQ, the yearly accumulating rate of metals should not exceed 0.2% in soil per year. Silver and bismuth are two metals that do not fulfill this requirement. The silver concentration in sludge decreased during the last decade, however the last few years, it has leveled off.

The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product?s intrinsic and extrinsic environment. The stability in UHT-milk and beverages similar to it have been studied in the past decades and a certain focus have been on age gelation which is a common defect in these type of products.

The purpose with our essay was to examine which clients/patients get treatment for alcohol problems from either health care units or social service units. We also wanted to find out how staff in these units considers the importance of social background in the assessment of treatment. The questions we have focused are: How do the clients/patients get in contact with the units? How does staff in these units consider the importance of social background in the assessment of treatment? How is the social background like for the present clients/patients? To fulfil the purpose with our investigation and to get answers to our questions, we performed an explorative examination and applied a qualitative method in the form of a semi-structured interview with six persons. The investigation showed that clients/patients get in contact with the units by looking for treatment by themselves or by relatives and other organisations.

Our purpose was to investigate the schools and the social welfare´s experiences of Roman children´s school situation in a Scanian town. We have done a qualitative investigation, interviewing 14 persons from both school and social welfare. Through the interviews we wanted to find the factors which influences the Roman pupils schooling and which efforts the professionals has to their disposition to influence these children´s school situation in a positive direction.The main result of our study is that the majority of the Romans is an isolated group, both in the Swedish school system and in the society. The Romans got access to the Swedish comprehensive school first in 1965, which implies that the Romans have a young school tradition. Most of the Roman pupils have a high absent, which is grounded in a complex of problems.
