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.

This is a qualitative case study of young womens? experiences of blogging about One Direction on the social media/microblogging platform Tumblr. The aim of this study was to find out what fan blogging is and why fans blog. We did this by creating an account on Tumblr where we invited young women between the ages of 16?29, who had active fan blogs dedicated to One Direction, to answer an open-ended questionnaire.

This paper analyzes the Swedish labor market during the interwar and early postwar period within the framework of modern labor market theory. The development of unemployment during this period - according to the commonly cited source of labor union reports - represents a conundrum for research. The unemployment rate rose after the initial diverse shock of 1921 and stayed at a permanently higher level for the rest of the interwar period. This development was reversed after World War Two when the unemployment rate decreased and stayed permanently low for the rest of the postwar period until the oil price chock of the 1970s.In a first step the available sources of unemployment statistics is investigated and compared. The general conclusion is that the labor union reports overestimate the level of economy wide unemployment while being a reasonably good indicator of movements in the rate.

When searching for better and more practical interfaces between users and their computers, additional or alternative modes of communication between the two parties would be of great use. This thesis handles the possibilities of using eye and head movements as well as voice input as these alternative modes of communication. One part of this project is devoted to find possible interaction techniques when navigating in a computer interface with movements of the eye or the head. The result of this part is four different controls of an interface, adapted to suit this kind of navigation, combined together in a demo application. Another part of the project is devoted to the development of an application, with voice control as primary input method.

The purpose of this study was to find an explanation for why Amnesty International in Sweden has seen an increasing number of members, while the number of participants at the national annual meeting has decreased.The method of the study was done with an inductive approach in which the problem has affected the choice of theory and empirical data. The empirical data has been collected through both qualitative and quantitative method in which the analysis was implemented with support by statistics and interviews.To strengthen the arguments in the paper, sociological theories on organizations are used and also theories about social movements.The conclusion of the study is that Amnesty International Sweden has undergone a transformation towards a decentralized organization because it is not longer relevant for people who are members to achieve the purpose of the organization to participate at the annual meeting. This because that these members accesses the recourses they want to achieve by working on a local level. The main conclusion of this study is that Amnesty has moved towards being an organization that to some extent are working as a social movement, where there is no longer any clear link between local work and the central board of Directors. .

In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

Iraq has in recent decades been with internal conflicts between ethnic groups. Despite the enormous wealth of natural resources, more than half of the population remains poor. War and corruption has led to lack of resources and worsening quality of the health sector leading to deteriorating health situation among the population. Womens role and experiences of health and health promotion is important in conflict affected countries to create health and well-being within the family. Objective: the objective of this study was to investigate the maternal experiece of promoting the health of children in an Iraqi context.Method:Aqualitative research methodology with semi-structured interviews was chosen.Six mothers from diffrent neighborhods in the city of kirkuk were interviewed.

One of the most important components of a harvester is the crane. Most harvester cranes are only possible to pivot (or horizontally rotate) at the crane pillar. Cranab in Vindeln, Sweden, has developed a new type of harvester crane which has an extra pivot point on the outer boom. This makes it possible to reach around residual trees, easing thinning work in dense stands. The aim of the study was to analyze if the use of a pivoting outer boom (POB) crane gave an increase in thinning production and if there were any differences in time consumption between the work elements for the POB crane and a conventional crane. A Valmet 911.3 equipped with a POB crane was used in the study.
