This masters thesis deals with Smoke spread via ventilation systems. One aim of the thesis is to investigate and explain the differences in efforts to prevent Smoke spread via ventilation systems in different countries. A second aim of this thesis is to investigate how frequently occurring Smoke spread via ventilation systems in Swedish buildings are. A third aim is to investigate how uncertainties in input variables to Smoke spread calculations will affect the result of calculation. To be able to do this the most important input variables are identified and analysed.

Can you ensure that your smoke detector will sense fire and sound the alarm in the middle of the night?In 80 percent of the cases where emergency pulls out, smoke detectors are missing where the fire occurred. In the year of 2009, 118 people in Sweden died in fires ? most of them would have survived if there had been a functioning smoke detector.Earlier development of smoke detectors has mainly been focusing on components that sense smoke and alert in case of fire. But in most cases the problem has not been whether the smoke detector was working or not as fully assembled, but rather that it was missing.

BackgroundDiathermy is the most commonly used surgical instrument in the surgical area today. Diathermy is used in surgery to cut and coagulate tissue. The use of diathermy releases chemical substances in to the environment in the form of diathermy smoke. Research shows that these chemical substances pose health risks to both staff and patient exposed to the smoke. To protect the interdisciplinary, perioperative team from the smoke, smoke evacuation systems can be used.ObjectiveThe purpose of the study is to highlight the work environment of the perioperative team when working with diathermy smoke.MethodThe study is meant to be implemented as an empirical descriptive sample survey.

Smoking is a health problem with a negative impact on virtually all body organs. Smoking can cause, for example, lung cancer, cancers in other organs and cardiovascular disease. There is also a social aspect of smoking. If individuals have many smokers in their environment, the risk to start smoking is increased, and for those who already smoke the chance of quitting will be less. Many municipalities today face smoke-free working to reduce smoking and passive smoking adverse effects.

The purpose of this essay is to test for significance between TED- spread and four different macrovariables, housing prices, Federal funds rate, Asset Backes Securities and mortgage volume. Multiple regression has been used to search for significance between the dependent and the four independent variables. Our data consist of quarterly reports from January 1998 to June 2008. Our conclusion is that all of the four variables show a significant relation with TED- spread. The model explains 76 percent of the variation in TED- spread..

In this thesis, the introduction of smoke-free restaurants and bars in several EU Member States in a policy convergence perspective is studied. The thesis sets out to explain whether policy convergence has occurred and the possible explanations connected with it. It is stated that 15 out of 25 EU Member States had introduced or decided to introduce smoke-free restaurants and bars up to April, 2006. Out of all the countries in the world, 35, including the EU Member States, had introduced or decided to introduce smoke-free restaurants and bars. The result is analysed by using policy convergence theory and by putting the case in a global environment where tobacco control has become an ever more central theme for public health policy.The EU Member States are different in several ways considered to be important factors for policy convergence, such as cultural, institutional and socio-economic similarities, and the conclusion is made that EU membership has been a most crucial factor for the rapidity of the policy diffusion.

Syftet med uppsatsen är att skapa en modell som kan förklara yield spread hos företagsobligationer. För att få en modell som nära återspeglar verkligheten inkluderas både företagsspecifika och makroekonomiska faktorer. Vi utgår från en kvantitativ studie och tillämpat en multipel regression på paneldata innehållande 24 bolag för att förklara yield spread hos företagsobligationer. Den teoretiska referensramen består av forskningsartiklar från främst USA men även Europa som behandlar riskkomponenter hos yield spread. Empirin är kvartalsvis redovisnings- och handelsdata under tidsperioden 2001-2005 som samlas in från finansiella databaser och behandlas med regressioner.

This essay studies how advertisements in various anti-smoking campaigns can influence and persuade by using anti-logos as counter-arguments to the tobacco industry's logos. In contrast to tobacco advertising arguments such as freedom (logos), pleasure (pathos) and trademark (ethos) the anti-smoking campaigns create anti-logos arguments with various connotations such as repulsive pictures and sexual implications to influence groups of people not to start smoking or to quit smoking.Advertisement of tobacco does not exist nowadays due to legal restrictions in the western world; however several decades of myths created in the consumer consciousness still exist. Thus one can speak of a tobacco advertising ideology that exists and the various anti-smoking campaigns trying to change that ideology.The purpose of anti-smoking campaigns is to conduct a kategoria of myth that tobacco advertisement has created over the years. Anti smoking organizations do this by creating a new ideology to affect consumer?s attitude toward smoking and the tobacco myth with an anti-myth.

This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.

In this Bachelor?s essay we discuss whether eWOM (electronic word-of-mouth) is perceived as advertisement or as normal information, which is not influenced by any company, on the platform Facebook. The information which we were interested in is the one spread by normal users, and user?s perception of it. To find our results we have conducted a study in which we have used the method interview, which gives qualitative results.

Syfte: Vi hade som syfte med denna uppsats att kartlägga sambandet mellan ett företags finansiella ställning och hur rapporter påverkar aktier med avseende på handelsvolym och spread. Metod: Undersökningen utgick från den svenska marknaden under åren 1998-2001. Genom att vi beräknade företagens soliditetsavvikelse från sitt respektive branschgenomsnitt, fick vi ett urval av finansiellt starka och finansiellt svaga företag. Därefter tog vi fram rapportdagar för dessa utvalda företag. Vidare undersökte vi om spread- och handelsvolymförändringarna kring dessa rapportdagar såg annorlunda ut för de finansiellt svaga företagen jämfört med de finansiellt starka.
