This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

Problem areaAlfa Laval is a world leading company in the heat transfers area and have the vision to continue to be that in the future as well. The company has a lot of press lines where the utilization is high and also has started to become old. Prognosis shows that there is an increased demand of heat exchanger in the future. This increased demand is not something that existing lines will manage. To build new lines cost a lot of money and take time so it is essential that new lines are correct from the start and not need to be rebuilt or a lot of time spent to trim it.GoalThe goal is to achieve 100% theoretical utilization of the press (the press shall press the amount of plates it is designed for).

The intrest and development of bioenergy and energy from renewable sources in Sweden has increased rapidly over the last few years. There are a whole lot of alternatives for those who would like to venture and invest in renewable energy production. Production of renewable energy opens up many opportunities for forestry and farming to venture a new branch of production, on basis of the primary production. Several of the new energy sources grows on farmland or in the forest. The opportunities exist in the primary products, as well as in refining and reselling, in the value chain of energy. The starting-point is the Farmer as an energyproducer. This master thesis studies the nature of farmer-own firms, who has invested in production of renewable energy.

As the number of people owning a smartphone rapidly increases so too does the opportunity for various researchers to exploit this technology. The possibility to recruit people to participate in research studies improves and with it the chance to get more diversified target groups in terms of age, socio-economic status, geographical location, etc.In this essay, I argue that the opportunities smartphones offer in terms of collecting research material is vastly underestimated in several areas, bearing in mind the advantages they present. In order to support my argument, I shall present a case study carried out in the research area of happiness ? an area where the use of smartphones has provided significant opportunities for research.In order to gather the advantages and disadvantages of this method of study from the participants? perspective, I have followed a happiness research study which is a collaboration between Umeå University and The University of Stockholm. I have interviewed the participants of this study in order to assess the advantages and opportunities that smartphones offer in research programs.Overall, the participants? opinion of this research method was generally positive and it was considered to be quite easy to participate in the study and respond to the questions asked.

This qualitative research overview consists of the State of knowledge about people with dual diagnosis. The focus is on what Psychiatry reform meant for people with mental disabilities. Author`s ambition has been to consolidate current understanding in the problem area. The purpose of the paper is to make an analysis of the State of knowledge concerning individuals within psychiatry with simultaneously addiction problems. The issues that will be processed are: what it means to live with dual diagnosis, how to coordinate cooperation efforts, and what is the evidence-based mode.

Bibaggen Apalus bimaculatus är en rödlistad skalbagge som förekommer i öppna sandiga miljöer och är starkt knuten till sin värdart vårsidenbi Colletes cunicularius vilken den boparasiterar på. Inventeringar av sekundära habitat i form av sand- och grustäkter har utförts i Västra Götalands län under tidig vår 2009 och 2010. Data från dessa inventeringar har i denna studie används i samband med undersökning av omgivande markslag runt dellokalerna/täkterna för att ta reda på om omgivande markslag påverkar förekomst av bibagge vid dellokaler/täkter. Inom sand- och grustäkterna registrerade inventerarna enskilda dellokaler där fynd av bibagge eller vårsidenbi gjordes. Om ingen av arterna observerades angavs en koordinat där en dellokal ansågs vara mest lämplig för en av arterna eller för båda arterna.

In this report female farmers use of technical equipment is investigated. There is little research made on this subject in Sweden, therefore this report can be seen as an explorative study. Research makes it clear that machinery, throughout history and even today, has been seen as a male area. Heavy machines are often associated with the same attributes as masculinity. Force, power, efficiency and control are some examples.

The purpose of this study is to analyze the economic effects of different fertilization programs both on stand- and forest-level. The study is applied on an objective sample of inventory data for a forest area in Kalix in northern Sweden. The forest area belongs to the forest company Sveaskog. The study includes different economic models and will be used as a support when the company decides how to invest and how much to invest in fertilization. The study investigates the economy of five different fertilization policies. For each program the rate of interest invested in fertilization and the cost for the extra produced volume has been calculated.

The purpose of this study was to make a survey of a larger company in Sweden to analyze if it complied to the stipulated Systematic Work Environment Management rules in Sweden. The company chosen was Hennes & Mauritz. The key question was to see if the company was examining and judging the risks, developing handling plans and if they were making yearly follow ups so that problems could be attended to. Further, I also wanted to examine if there was lack of competence within different departments as well as give some substantiate proposals on educations in Systematic Work Environment Management. The method used to investigate this was interviews and observations on how the Systematic Work Environment Management was handled in the company.

Gothenburg municipality has a lot of natural water. This paper enhances the function and importance of water in the city. It also deals with the problems of sewage water and flooding. Gothenburg has reached an advanced stage of water planning. By developing a Waterplan, the municipality highlight that water has an important position in the urban planning.

AbstractMany opinions are divided on what religious freedom should protect and the area is unexploredin preschool. Is it the parents, the child or preschool teacher right? The aim of the studywas to investigate Maria klasson Sundin´s concept and theoretical models of religious freedomfor children through three Swedish preschool settings and also how three teachers interpretsand expresses children's freedom of religion. Through a qualitative interview study theaim was to investigate how the concepts of religion, autonomy and freedom is interpreted andexpressed by the teachers so a picture through this three concepts can categorise the teachersin a model; freedom of thought, tradition and life interpretation model so a broader picturecan be made to understand how the children's freedom of religion is expressed in the preschoolsetting and how the teachers work. The Result showed through the analysis that themodels fail to categorise the teachers in any theoretical model but on the other hand the understandingof preschool teacher?s expression and interpretation of the concept of religion,autonomy and freedom showed both diversity and lack of knowledge on the subject mattersreligious freedom which fall within the child rights issues.
