Ovarian stimulation in assisted reproduction often leads to the production of a high number of oocytes. After fertilization of these oocytes, the resulting embryos can be cryopreserved for later use. Vitrification is a recently introduced method for cryostoring embryos, showing high survival rates for both cleavage stage embryos and blastocysts. Characteristic of vitrification are high concentrations of cryoprotectants and ultra fast freezing which makes the material glassily. A major concern with vitrification has been the direct contact of the cryo-solutions with liquid nitrogen.

In this study I?ve examined bilingual high-school students? experiences of their education held in their native language. The purpose of this study is to examine bilingual high-school students? experiences of how their school organizes the education that?s held in their native language, and how the students feel that the education in their native language has helped their overall language development and also in terms of learning in general. To complete this study I?ve interviewed six high school students and analyzed their answers using other studies and theories on this subject.

A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.

The aim of this paper is to examine how teachers experience their possibilities to develop democratic teaching in high school and how they reflect upon their position of power within the teaching situation. Four professional high school teachers have been interviewed for the study. The theoretical perspective of the study is an intersectional view on power and a view on democratic teaching which is partly built on the high school curriculum, but mainly defined by deliberative conversations, anti-oppressive education and norm-critical education. The result of the study is focused on three themes, which were shown in the analysis of the interviews. These themes are: choices of teaching content,  authority of the teacher and democratic teaching.

In Sweden, the eutrophication of lakes, water courses and the coastal areas is considered the major threat to aquatic ecosystems and therefore actions taken to reduce the nutrient load to aquatic system including the Baltic Sea has high priority. There are many different sources of phosphorous and nitrogen and domestic wastewater is one contributing factor to the high load. Especially waste water from households that is not connected to municipal sewage treatment or a local small scale plant with appropriate nutrient removal efficiency is considered a problem. These types of households are quite common in rural areas in Sweden and in areas where summer houses has been converted to permanent living. Swedish legislation now permit the municipalities to decide in which areas within the municipality higher demands of the local small scale treatment facility should be met by the households (i.e.

Sense of coherence, SOC, is a way to study health and wellbeing in a salutogen perspective. SOC is a theory that Aaron Antonovsky came up with and it involves three elements; comprehensibility, manageability and meaningfulness. These three elements is a objective way to look at our existence. The aim of this study was to examine how high the pupils sense of coherence was in the grades 1, 3 and 6 in a school in Karlstad. And with the result as starting point have a discussion around the pedagogical consequences and which educational work procedures we can use to work with SOC in school.

Sound surrounds us in a great extent, we all have experiences of sound and this phenomena has a great meaning in our lives. High levels of sound might be harmful for your hearing and might also cause related difficulties such as tinnitus and sensitivity to sound. Studies reveal a connection between the attitudes toward high levels of sound and the risk behaviours in these situations. The purpose of this study was to explore the experiences and meaning of sound and whether the attitudes toward sound will reflect in a family consisting parents and adolescents. A family consisting two parents and two adolescents participated each and one of them in an interview in this qualitative study that has been carried out of a phenomenological approach.

The purpose of this essay has been to seek understanding of how young people in high school and adult education experience the use of educational media tools in teaching. Examples of questions submitted material has been: What are the positive and negative experiences of ICT in the classroom?The essay is of a qualitative nature, in which five students were interviewed about their experiences of ICT in the school environment. The result is analyzed from a sociocultural perspective and from an inward-student perspective.The results showed that students felt that it was difficult to absorb many of the ICT facilities as sources of knowledge in the school environment. Due to lack of quality in teaching material and difficulties of the pupils to sort out the important information of the injected..

The purpose of my study is to gain insight into how the education system (particularly social studies) is morally-minded based on the governing documents, former students and a textbook. I wanted to find out what morally-minded means and if it has a big role in social studies. Through interviews with former high school students (when my thesis is aimed at high school) I wanted to find out how they felt their social studies were educational and which the values that they had taken on from the lessons. I also chose to analyze a textbook to get a broader understanding of how the morally-minded education is written in specific areas relating to social studies. My study is a qualitative study and what I came up with is that the former students consider their social studies teaching lacked to some degree when it came to the morally-minded education. My investigation concludes that the morally-minded education is important in social studies as the purpose of social studies is to promote active democratic citizens.

Food-poisoning is a major health problem and an estimated half a million Swedes are food-poisoned annually, with acute gastroenteritis as a consequence. One of the major causes of contaminated foods is related to food- and waterborne viruses. To be able to trace back the source of contaminant, the method of detecting viruses must be specific and sensitive. No standardized method for detecting foods for sapovirus exists today. The aim of the work described in this bachelor thesis is to implement and opti-mize a real-time RT-PCR method for the detection of all genogroups of human sapovirus in foods.

In organic animal production, synthetic amino acids are not allowed. Therefore, a higher level of crude protein is needed in the diet to pigs, which lead to more nitrogen (N) excreted in the faeces and urine. N can be emitted to the air in the form of e.g. ammonia (NH3), which contributes to eutrophication and acidification and as nitrous oxide (N2O), which is a very potent greenhouse gas. The emission of N can be reduced by e.g.

Arvika Fastighets AB is a municipal subsidiary tasked with managing all green areas in the municipality, with a strong focus on the City Park and plant beds in the city centre. These areas generate large amounts of green waste, which is currently transported to the municipality's composting area at Lycke. Currently, the material is piled up and turned once a year without using the resulting soil for flowerbeds, lawns, and shrub/tree plantings. The purpose of the study is to determine if Arvika can compost the green waste in a more efficient manner and produce weed-free soil ready to be mixed into various substrates for different purposes. Interviews with the Swedish Church and several municipalities in Sweden have been conducted to learn from their experiences and knowledge of how they make their composting work.

AbstractThis study examines the use of dance in the special education classes in high school. The purpose is to study the teachers? thoughts about dance within this school form. I want to see if they see any gains from having dance as a subject, and what might these be? Earlier research states that dance has a positive influence on mentally handicapped children and young people, and that it strengthens their general development.

The purpose of the study is to examine how teachers and students believe that graphing calculators affect the teaching of high school mathematics courses. By becoming aware of this, teachers and teacher students have the opportunity to reflect on the use of graphing calculators in their teaching. The empirical base consists of interviews with teachers and a survey among students at two high schools in southern Sweden. The results show that teachers especially consider the graphing calculator as a tool, much like paper and pencil. They use it if and when it is deemed able to contribute in a significant way in their teaching, either to save time and/or to help deepen the understanding of various mathematical concepts and methods.

Abstract Road cycling is well established and has always been described as a highly endurance sport. To be able to compete in such a demanding sport the physiology of the athletes needs to be greatly developed. This review will focus on high intensity interval training and its impact on the physiological characteristics of competitive road cyclists. The main difference between different levels of competitive road cyclists seems to be the capacity to maintain a high sub maximal power output over a long period of time in order to succeed. High intensity interval training, from 30 seconds to 5 minutes, leads to improved VO2peak, aerobic peak power and time trial performance.
