The purpose of this report is to study the relationship between the rescue service fire prevention activities and the number of arson fires in schools. An objective of the project is also to investi-gate the need of developing national methods for fire prevention. The results are based on a questionnaire study among 35 fire departments and further interviews with five of them. The results indicate that there is a relationship between the rescue service fire prevention activities and the number of arson fires in schools. The relationship is positive in the sense that arson fires in schools decrease with increasing prevention activities.

In this project, we are studying the material flow and the information flow of sample materials and the appurtenant report of deviation for the purpose to be able to suggest better solutions. The sample material, which is to be analysed, is to be continuously taken from the production flow. The purpose is to navigate the process by the results found by the analysis. Because of this, it's very important that both methods of analysis are ensured and that the sample material is representative for the production flow. However, even more importantly, is that activities and transportations, combined with both flows, must perform in a quick and correct way in order to maintain or improve Höganäs AB's competitive strength.According to reports are about 20 products per day not available, for loading, at the time of delivery.

The purpose of this paper is to present a possible understanding of why the company Tekola is segregated according to sex. In accordance to this purpose, an understanding of how the segregation affects the employees in relation to power, values and possibilities is discussed. The theoretical understanding is that the organization of men and women within Tekola is done in close connection to creation of the meaning of gender in Tekola. This, in turn, affects and is affected by the recruitment to and within the company. Through the study of statistics from a survey, five interviews with employees and former employees and Tekolas? equality plan, we are able to see the possible existence of a glass ceiling, and a culture of homosociality, which affects the possibilities of women to enter the company and also to gain full entrance to power-positions in a negative way.

Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

En god arbetsmiljö är en lagstadgad rättighet för arbetstagaren enligt Arbetsmiljölagen. Arbetet med att säkerställa en god arbetsmiljö kallas arbetsmiljöarbete och är en nyckelfaktor för att skapa hälsosamma och attraktiva arbetsplatser. Medarbetarundersökningar är en undersökningsmetod i det systematiska arbetsmiljöarbetet men kan också användas i syfte att ta reda på medarbetarnas uppfattningar om sin arbetssituation med målet att skapa verksamhetsförbättringar.I denna studie har syftet varit att undersöka vilken roll som medarbetarundersökningen spelar i chefernas arbetsmiljöarbete. Studien undersökte hur cheferna arbetar med arbetsmiljöarbete och hur arbetet med resultatet från en medarbetarundersökning genomförts. Studien genomfördes på en funktion med tre organisationsnivåer och bygger på 12 kvalitativa intervjuer med funktions-, avdelnings- och enhetschefer.Studien visar att medarbetarundersökningen spelar en viktig roll i chefernas arbetsmiljöarbete på alla organisationsnivåer både som diskussionsunderlag i ledningsgrupper och i dialogen med medarbetarna samt som bevis på att genomförda arbetsmiljöinsatser fungerar.

Several surveys indicate that corporate leaders still consider the aligning of IT and business functions as a top management issue. The aim of this thesis is to illustrate how coordination emerges between IT and business departments and how formal structures intended to coordinate are influenced by human action. To deepen the understanding of this phenomenon we seek to analyze IT/business coordination from a perspective based on practice theory. A field study was conducted where observations and informal interviews were carried out at the IT department of a global company. The empirical analysis indicate that coordination problems between IT and business departments is in part affected by embedded factors such as different goals and perspectives on how IT is to be used in the organization or how to design IT related processes.

Vi har under vår verksamhetsförlagda utbildning, utifrån egna erfarenheter och genom att läsa forskning fått en förståelse för att barns föreställningar om naturvetenskapliga fenomen inte stämmer överens med verkligheten. Det har också gett oss en uppfattning om att det saknas läromedel inom astronomi för barn i de yngre åldrarna. Grundat utifrån detta valde vi att utveckla ett läromedel inom astronomi.Läromedlet är tänkt att vara lättillgängligt och lättanvänt för lärare, samt att läromedlet ska uppfylla ett av de centrala kraven i Lgr 11 för årskurs 1 till 3 inom naturvetenskap: ?Jordens, solens och månens rörelser i förhållande till varandra. Månens olika faser?.För att kunna ta reda på vad ett bra läromedel är och på så sätt få tips till vårt eget så genomfördes en enkät på våra partnerskolor.

Vid tillverkning av pappersmassa på sulfatmassabruk kokas vedflisen med kemikalier för att frilägga fibrerna. Kokkemikalierna och andra ämnen från veden, framförallt lignin, återfinns i svartluten efter koket. Ligninet är vedens mest energirika förening som med fördel kan användas som energikälla vid förbränning. Idag förbränns ligninet i svartluten i sodapannan. För att skapa utrymme att förbränna en större mängd svartlut i sodapannan kan en del av ligninet i svartluten separeras, fällas ut, och sedan användas som ett biobränsle. Detta biobränsle, det utfällda ligninet, kan användas antingen internt på bruket i mesaugnen och på så sätt minska oljeförbrukningen eller externt i någon annan typ av förbränningsanläggning. I detta examensarbete har metoder att fälla ut lignin ur svartlut genom pH- sänkning med CO2(g) eller genom tillsatts av Ca2+-joner studerats.

The aim of this study is to examine what preschool teachers within Reggio Emilia inspired early childhood education express as important regarding the physical indoor environment in preschools. The study is implemented with a qualitative method and is based on four interviews with preschool teachers that have been involved in a course on Reggio Emilia. The interviews were complemented with four observations on the departments where the preschool teachers work. A second aim of this study is to examine how the relationship between the teachers statements correlate with the environment they have created at their preschool. The collected material was gathered and then categorized.

In this project we have used the theory of analytical mechanics to derive equations of motion for complex mechanical systems in order to study their behaviour over time. Even if the theory provides powerful tools to tackle tough problems which would be very hard to solve by methods of Newtonian mechanics, you are still relatively limited without running any computer simulations. One realises that in a faster rate it will be an incredibly difficult task to find an analytical solution when the degrees of freedom increases. Even if one would succeed to derive the equations, one still has to solve them to get the information of the systems behavior. Of experience one knows that the equations in general are nonlinear and hence must be integrated numericaly.

The purpose of this essay was to examine whether there were any differences in social workers way of investigating boys and girls, age 13-15. The main questions we wanted to answer were; which were the factors that the social workers focused on? Did the investigations lead to a measure and if so, which one? How were risk and protection factors described and ana-lysed?To answer our questions we read and analyzed 22 reports, written by social workers 2004 at the department for teenagers and families at a social welfare service in Sweden. We came to the conclusion that there were some differences, but these were few and not extensive. Recreational activities was mentioned in a higher degree in the boys reports while health, housing conditions and network were mentioned more often in the girl´s reports.

This report is the result of a thesis work in Integrated Product Development, regarding hygienic features in dishwashers and especially disinfection by the use of steam.The thesis is performed at Electrolux Primary Development Dishcare in Stockholm and in collaboration with the Department of Machine Design at the Royal Institute of Technology.The targets of the thesis are to prove the advantages of a technology suitable to implement as a hygienic feature inside a dishwasher and to realize a functional prototype of a differentiated hygienic feature that does not exist on the market today.The process followed to perform the thesis is the process defined for Electrolux Primary Development.The technology chosen for development is disinfection by heating the water on the surface of the dishware, by the use of steam.A number of tests on how steam behaves when injected into the dishwasher tub have been performed, providing the results that have been taken in consideration when designing the prototype.The prototype consists of a pipe system provided with nozzles to eject the steam into the upper parts of the dishwasher. Tests of the final prototype show that thermal disinfection of water in a dedicated area of the tub can be reached within 9 minutes. The operation requires 0,17 liters of water and consumes 0.2kWh..

Tappningsstrategin för Vänern ändrades i ett beslut från Länsstyrelsen i Västra Götalands län och Vattenfall AB, på uppdrag av regeringen år 2008. Detta gjordes för att minska risken för översvämningar i Vänern.  Åtgärden var föreslagen av Klimat- och sårbarhetsutredningen, som försökt utreda konsekvenser av klimatförändringar för Vänern i ett framtida förändrat klimat. I utredningen används en metod för att mäta kostnader. Metoden är en kostnads-nytto-analys (Cost-Benefit-Analysis; CBA) som användes för att utvärdera bland annat Vänern med omnejd. Enligt denna uppsats saknas det värdering för naturmiljö och sociala faktorer i denna utredning.

I detta examensarbete har jag undersökt förmågan hos nautiker att ta fram och tillgodogöra sig information från radar och ARPA för sitt beslutsunderlag i trafiksituationer. Syftet var att få förståelse i om fartygsbefäl haft svårigheter att få fram denna mycket relevanta information. Detta gjordes med hjälp av förstudier i form av intervjuer med erfarna fartygsbefäl. Dessa intervjuer gav kriterier som möjliggjorde analyseringen av 13 olycksfallsrapporter, vilket utgjorde litteraturstudien. Dessa rapporter var författade av engelska Department of Transport, Marine Investigation Branch(MAIB), Statenshaverikommission(SHK) och  Sjöfartsverkets rapportserie(SjöfR).
