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.

The content of the following report is the summarized result of three students thesis at Blekinge Institute of Technology in co-operation with Water Jet Sweden AB. This report will give the reader a description of principles how to measure the abrasive mass flow in a waterjet cutting system. The work began with a visit to Water Jet Sweden AB to get a closer look at the problem. When the analysis of the problem was done the criteria were defined in the form of demands and desires. The main task of the criteria was to guide the search for the solution. The work proceeded with an extensive search for abrasive flow meters along with obtaining information about flow measurement in general. When the search for abrasive flow meters resulted in nothing all the efforts were concentrated on finding a principle of measurement that could cope with the criteria.

AbstractThe purpose of this study was to describe and compare the degree of selfreporting succession to the basal hygienic routines of emplyees working in municipal old peoples care versus hospital care. It is also to describe the access of material available in prevention of cross infections. The study was also carried out with a comparative and quantitative run up design. The study is based on a questionnaire in the district of Gävleborg in the spring of 2009. Nurses, auxiliaries and carers whom were in close contact with patients were asked to join the study.

The aim of this theoretical study is to explain how the notion of the Other and Otherness affect individuals possibilities to form multiple, personal identities. This is done by the use of the theory of the Other and the construction of identities. In my analysis I will be using the power perspective presented by Lukes. The purpose of my study is also to investigate whether a focus on similarity over difference between groups can change the situation for individualsMy study shows that otherness affect individuals identity constructions through stereotyping and categorising. This is made possible by the use of power from outside and inside different groupings.

The porpuse of this paper is to find out how three teachers working in years four to six in a Swedish school say they use formative assessment and how they use it in educational practice, and if there is a difference in the use of formative assessment between year four, five and six. Formative assessment is the kind of assessment that aims to enhance the student?s learning, as opposed to summative assessment wich is intended only to summarize student?s accomplishments. To answer the purpose, I conducted qualitative interviews with the teachers, and observations in each of the teachers? classrooms.

The purpose of this study has been to investigate the prospects for identifying and prosecuting individuals suspected of war crimes, within the process of exclusion from refugee status under article 1F(a) of the 1951 Refugee Convention, and using subsequent mechanisms for extradition or prosecution in international criminal law. A number of principles within human rights law and public international law have been advocated by the UNCHR and several human rights NGOs as necessary for a thorough application of the exclusion clauses; one that takes individual responsibility into account and upholds the aims and purposes of the exclusion clauses. There is a discussion as to whether specialised or accelerated exclusion procedures are justified for reasons of security and efficiency, or if they put the rights of the individual at risk and limit the opportunities for gathering information to support investigation and prosecution of the crime in question. Apart from the instruments of asylum law and procedure that have emerged within the EU harmonisation process, there are no general, binding rules on the procedural aspects of the exclusion clauses. One principle that regulates the consequences for the individual of exclusion from refugee status and decisions on extradition is, however, the principle of non-refoulement.

In the beginning of the 21th century several successful companies filed for bankruptcy. These bankruptcies have been known as large accounting scandals and the largest scandals did Enron and Worldcom stand for. These bankruptcies arose without any warning signal from the auditors about the companies? financial problems and their inability to continue as a going concern. The bankruptcies damaged the reputation of auditors and broad criticism has developed at the auditors? inability to discover companies? financial problems and their unwillingness to reveal a going concern opinion in the audit report.

According to the arm?s length principle, transactions between associated multinational en-terprises (MNE) shall be based on the same conditions as transactions between unrelated parties. This means that intra-group prices on cross-boarding transactions must be at arm?s length range and consistent with conditions in the open market. The arm?s length principle is expressed in article 9.1 of the OECD Model Tax Convention and Chapter 14 section 19 of the Swedish Income Tax Act.When transfer pricing between associated MNEs is not reflecting the arm?s length princi-ple, states face the possibility of losing tax revenue.

AbstractThe purpose of this essay is to discover the driving forces in top athletes, concerning training, body image and social positioning. Furthermore the object is to study how important being fit is for social reasons in today?s society. The athletes have been interviewed face-to-face and described their personal drive regarding training, their goals and the significance of the sport. They have also described how they see the image of the ideal body that currently exists within the field of sport and society and how training affects their own body image.

The rise of the Swedish Democrats, as a political party in Sweden, has been surroundedby controversy both within and outside of the media. As such a polarizingtopic, the party has been the focus of negative and positive attention. On onehand it has been considered a racist and xenophobic party due to its policies onimmigrants. On the other, it has also been seen as a solution to what has been consideredby some to be a constant problem in Sweden, for those same policies.These policies are motivated by what the party perceives as a threat to Swedishsociety. That is to say, immigrants are a threat to Sweden because of thechanges they impose on the Swedish identity.

The aim of this master?s thesis is to investigate a information center called ?Infoteket om funktionshinder?. The purpose of Infoteket is to collect information about disabilities and make it accessible to people with disabilities, their relatives and public. In this survey I will analyze how Infoteket can help people with disabilities to achieve empowerment. I use empowerment as a theoretical framework as Jay A.

There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

Aim:The aim of this study is to examine similarities and differences in eating habits in students ages 16-19 in high school.Questions:How do eating habits differ between adolescent athletes and non-athletes?What significance does living conditions and religious background have on the eating habits of adolescents? Method: This study is of a quantitative approach using survey questions.The method used was questionnaires. Three schools participated in the study. The school provided programs with and without athletic orientation. My purpose was to give out 200 surveys but in the end the total of handed out surveys landed on 141.

People are usually directed towards each other in conversations, to make it easier to hear what is being said. Algorithms for voice and speech recognition works in a similar way, regarding the microphone direction towards the sound source. In this thesis in electronics has therefore a servo control with binaural sound localization been implemented on a microcontroller connected to two microphones.When people perceive sound, the brain can estimate the sound source direction by comparing the time taken by the sound reaching one ear to the other [1]. The difference in time is called the interaural time difference, and can be calculated using various techniques. An exploratory comparison between the techniques cross-correlation and cross-spectrum analysis was carried out before implementation.

Education systems face a number of challenges regarding social justice, diversity, difference, and inclusion and membership for all students in the groups that schools create. This invokes questions of how well these challenges are met in curricula and teaching materials. Through discourse analysis of eight Swedish geographical textbooks, this essay aims to seek out the perspectives surrounding difference within the subject of geography. It concludes that the idea of fixed homogenous cultures as meaningfull in differentiating among people dominates throughout the latter half of the 20th century and during the last decade. In addition, it concludes that the discourse surrounding diversity in Swedish geographical teaching materials mainly has a binary liberal view of plurality focused around tolerance.
