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.

By interviewing 10 people in leadership positions from various companies and      countries, this thesis had as main objective to find out how the view the of what environment promotes the intrapreneur to make the organizations more competitive and successful. By transcribing and interpreting the interviews, we have found the keywords that could answer our research question. Our method has been based on a qualitative approach with an inductive direction. The leadership has been shown to have a significant role in terms of company culture and the intrapreneurs ability to contribute to the development of the organizations. The culture is essential.

This paper is a literature study aiming to describe scientists newest theories andknowledge concerning the El Niño and Southern Oscillation. Firstly I have described the?normal? conditions with rising and sinking air in Hadley- and Walker-cells in theequatorial Pacific and from there moved on to explaining the reversed circulation patternsand higher sea surface temperatures (SST) leading to rising air and anomalousprecipitation in eastern Pacific constituting the El Niño phenomenon. My outermostinterest regarding El Niño has been the associated teleconnections, especially in nontropicalareas. I have described the El Niño effect on the Indian summer monsoon, ontropical cyclones and on storms and precipitation on higher latitudes.

To build a sustainable future should we first understand that; every aspect of our daily lives can affect the environment. It?s important that we take responsibility for understanding how we impact the environment and change our actions accordingly. The worlds total energy consumption equivalent to 80 million MWh / year. This corresponds to about 220 million MWh / day.Energy consumption is one of the main reasons for increased greenhouse gases when the reduction of this consumption has a great demand worldwide.In order to prevent the energy that consumed the buildings must be energy efficient but there is a conflict between radon ventilation and energy conservation in a building, given that ventilation can consume as much energy (currently 29-59% of energy-efficient houses use), especially in a cold climate as in Norway.

During spring 2012, six students at the Royal Institute of Technology in Stockholm carried out agroup project in the field of mechatronics as part of the thesis for the bachelor degree. The resultwas a robot with active balancing and the purpose of this report is to describe the development,manufacturing and problems that arose during the project. The finished robot has two wheelsmounted in line with each other, like a bicycle. Measurement data from an accelerometer and agyroscope are used together in a complementary filter for determining the angle from the verticalplane. For balancing, a PID controller was used to control the rotation of a reaction wheel, whenaccelerating causes a straightening torque.

The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.

The consumer society exploits the earth?s resources more than the earth itself has capability to produce. This over-consumption causes a mass production of products, which mean that more greenhouse gases are being emitted to the atmosphere. This is one of the reasons why the earth?s temperature is rising, where the result of it is worldwide disasters.

This work examines the students´ thoughts on climate change with a focus on carbondioxid through photosynthesis and the carbon emissions from cars. The study is based on two subject areas, one with a focus on enhanced greenhouse effect, and the other focusing on photosythesis. The survey was conducted by means of qualitative interviews with students in grades four and six. The results describe that student´s understanding for photosynthesis and the carbondioxids function for photosynthesis doesn´t change significantly from grade four to grade six. I have divided the students inte three levels based on their understandingof the various fields, and their use of adequate concepts.

Syftet med studien var att ta reda på om det går att predicera medarbetares organisationsengagemang utifrån organisationskommunikation, såväl mellan chef och medarbetare som medarbetare emellan. Detta gjordes genom att 118 medarbetare fick besvara en enkät bestående av delar från Communication Satisfaction Questionnaire (Downs & Adrian, 2004). Studiens huvudresultat visade att organisationskommunikation delvis kunde förklara variansen i organisationsengagemang. Resultaten diskuteras i termer av hur och varför organisationer som har en upplevd god organisationskommunikation, både mellan medarbetare och chefer och medarbetare emellan, skapar ett starkare organisationsengagemang hos sina medarbetare..
