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 thesis researches the construction of the Swedish masonry heater called r?rspis. A r?rspis has an inner smoke channel system that stores heat and it was developed in the early 19th century alongside the Swedish kakelugn (tiled stove). Unlike the tiled stove, the R?rspis was commonly found in simpler environments and is part of the cultural her itage of the rural population.

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.

Syftet med den föreliggande studien har varit att beskriva och skapa en djupare förståelse för vad det innebär att vara sopdykare i ett postmodernt konsumtionssamhälle. Den teoretiska delen i studien har bestått av Zygmunt Baumans teorier om konsumtionsliv, globalisering och postmodern etik. Material har bestått av fem intervjuer med två kvinnor och tre män som sopdyker regelbundet. Den metodologiska utgångspunkten har varit att tolka materialet utifrån ett hermeneutiskt förhållningssätt i tre olika nivåer. De begrepp som tillsammans utgör en huvudtolkning om vad det innebär att vara sopdykare i postmoderniteten är: En ambivalent konsumtion, alternativa kicksökare, den kollektiva gemenskapen, tänk globalt ? agera lokalt, den gode stråtrövaren och gammaldags moral.

Feline asthma is a condition very similar to the respiratory disease affecting humans. It is causing, among other things, a constriction of the bronchial airways, an increase of mucus production and damage to, or erosion of, the epithelial membrane. The symptoms occur intermittently and do, in most cases, evolve during a long period of time. The aim of this essay was to investigate whether there are any nursing routines for feline patients with asthma in animal clinics and animal hospitals in Sweden, and if so, to compare similarities and differences. A literary study of research material also led to a suggestion of how to form a nursing routine for this type of patient.

This report examines the prerequisites for LEDs to replace other technologies indifferent applications. How does the different technologies for light generationwork and what are the advantages and disadvantages? The various technologieslimitations and characteristics provides the opportunities for the LEDs.This report describes a test-construction built to examine what practical arrangementscan be built with modern light emitting diodes, in order to showsome of the possibilities. The construction consists of three different applications,a high power lamp based on cold white LEDs, one based on warm whiteLEDs for the evaluation of the light characteristics and a RGB-LED based lampable to mix any colors quickly and seamlessly. The test construction also containsthe essential peripherals including control-electronics, optics and a custombuilt watercooling solution.The potential for LEDs is huge but it is complicated to build LED based applicationsdue to the limitations which mainly includes the electronics and theneccesary cooling.

Att sluta eller inte sluta? En litteraturstudie om tobaksavvänjningsmetoder Bjellman, K. Tobaksbruket har en lång historia, och de tobaksrelaterade sjukdomarna kostar samhället miljarder i sjukvårdskostnader och produktionsbortfall varje år. Andelen rökare minskar stadigt i Sverige, idag röker ca 15 procent av befolkningen. Resultaten från olika metoder för tobaksavvänjning är tämligen blygsamma, och ugefär nittio procent av de som slutar röka gör det på egen hand.

The aim of the present study was to examine smoking behaviour and motivation for smoking cessation in patients at a dental clinic. Another aim was to examine if the patients had been asked by the dental staff regarding their smoking habits.Twenty-two patients from a student clinic and twenty-one patients from a Swedish Public Dental Service Clinic in southern of Sweden participated in the study. Participants consisted of eighteen women and twenty-five men. Data collection was carried out using a questionnaire that was directed at smokers. The questionnaire was answered in connection with the visit to the dental hygienist.The patients smoked between eight and twelve cigarettes per day and had on average smoked between 5 -15 years.

Denna undersöknings syfte har varit att utreda när och hur subkulturen klubbkultur växte fram i Malmö, vilka som tog den hit, vad som då definierade kulturen och hur detta skiljer sig från idag.Ytterligare syfte har varit att undersöka hur klubbkulturen som sägs genomsyras av en universal jämlikhet, på olika sätt, såväl inkluderat som exkluderat människor från att delta i den. Genom kvalitativa intervjuer med sju aktörer aktiva inom klubbkulturen under det sena åttiotalet och tidiga nittiotalet, men också genom min egen bakgrund som besökare, arrangör och DJ, målar detta arbete med hjälp av muntlig historia, ett kulturanalytiskt perspektiv och med Sarah Thorntons teorier om klubbkultur och subkulturellt kapital upp historien av hur Malmös klubbkultur växt fram samt de viktiga faktorer som definierade den och på vilka sätt kulturen både exkluderade och inkluderade. Resultatet berättar en historia om en ny upprorisk motkultur som under det tidiga nittiotalet utvecklades från att ha varit en brett inkluderande, men samtidigt en underjordisk gör-det-själv-kultur, till att bland annat genom tyst exkludering i form av nischade smakgemenskaper och konsumtionssymboler, utvecklas till en uppdelad kultur som inte bara positionerade sig mot det så kallade mainstreamsamhället utan även mot andra klubbkulturer..

This thesis has been performed at Clinical Chemistry at Sahlgrenska University Hospital in Gothenburg. The purpose of the project was to investigate new and alternative ways to determinate synthetic cannabinoids by gas chromatography-mass spectrometry. Currently, the possibilities to quantify synthetic cannabinoids are very limited. This can lead to an increased use of synthetic cannabinoids as the risk of detection is low, which may be known by drug users. The synthetic cannabinoids are sold mixed with different herbs and have varying names like Spice Gold, Spice Silver, K2, Smoke and Pot-pourri.The synthetic cannabinoids analyzed were JWH-018 and JWH-073, which are commonly found in seized Spice material.

I want to look at the possibilities to start selling hot water from a small district heating plant with bioenergy. My reason for doing this project is to look at a new business opportunity for our farm. Our company have less work during the winter time compared to the spring and this project will give us more work during the winter. I also want to take as much material as possible for heating from our farm in order to increase the value of the products from the farm. The project is in a village near us, where we should support a school, a churh, a home for the aged, a kindergarten and a parish hall with heat. In my work I have compared two different alternatives with each other. The first alternative is to put a central heater in one of the buildings, the home for the aged, in which we will burn oat.

Turismen bidrar, i likhet med de flesta industrier, med olika negativa effekter på miljön. Problem uppstår när antalet besökare överstiger ett områdes ekologiska bärförmåga, det vill säga när miljön i ett område skadas, eller växter och djur trängs undan från naturområden på grund av människor. Antal utförda dykcertifikat har mer än fördubblats sedan 1990 och det har genom tidigare forskning fastställts att fritidsdykning bidrar till slitage av korallrev och övrig undervattensmiljö. Det krävs en långsiktig förändring i dykarnas beteende och det som ännu inte analyserats är hur dykarrangörer arbetar för att undvika påfrestningar av undervattensmiljön, därmed saknas ett undersökt organisationsperspektiv. Syftet med uppsatsen är att undersöka hur miljöledning och kommunikation kan användas för att främja en långsiktigt hållbar upplevelseprodukt.

To provide our company a new business opportunity I have in this essay examined the economical possibilities to sell energy. I have chosen to do a case study on my own farm in this essay. The farm is focused to cropping and also have some properties for hire. The farm is situated in the village of Fjelie and that?s where the opportunity for selling heat are. Fjelie has about forty houses. The idea is to build a plant where straw is being used as fuel.
