Disturbances, such as fire and wind, are important for saproxylic beetles (= beetles depending on decaying wood) to gain substrate in boreal forests. Clear-cutting is an example of a man-made disturbance. Measures such as prescribed burning have been made to resemble natural disturbances. The aim of this study was to see which clear-cut characteristics are important for the occurrence of the saproxylic beetle Upis ceramboides. This is a species favored by open habitats and is said to respond positively to forest fires. The distribution area in Sweden for this species has decreased during the last two centuries and I wanted to see if there were differences between clear-cuts in Hälsingland, where it is very rare and decreasing, and Norrbotten where this study was conducted.

Nowadays Wireless LAN is playing a more and more important role in network systems. After 1999, in which the IEEE organization published its Wireless Local Network standard 802.11[1], many people saw the advantages of the standard but also the lack of support for multimedia streaming. A lot of research work has been done on the proposed IEEE 802.11e standard draft during the past 4 years. It is supposed to be able to fully support Quality of Service. The final version will be published early in 2004.

This report describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ångström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data ? even stream live video - through an optical fibre to a monitor in a ground station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.

Title The User Created Fire ? Risks and Opportunities with Crisis Communication in Social Network SitesAuthor Charbel SaderCourse Master Thesis in Media? and Communication Studies, Department of Journalism and Communication, University of GothenburgSemester Spring semester of 2013Tutor Nicklas HåkanssonNumberof pages 75Purpose To find a deeper understanding of the digital media?s role in Swedish society in relation to crisis communication.Method Qualitative approach using focus group interviewsMaterial Semi structured focus group interviews with a total of 18 participants in five groups. The focus group sessions were made during February, March and April 2012.Main results The main findings in this study are that users expect the communication flow in social network sites (SNS) during a crisis is to be a shortcut to information without a detour through organizations or traditional media. Although we find personal gratification, like interpersonal communication, quick information and sharing feelings and experience with others by using SNS during a crisis, users also tend to be hesitant about the credibility of the shared information. Alongside the user created content, we look to professional media experts and organizations as a guarantee for the veracity of the shared information.

The purpose of our study is to see how the interaction between the social services and police work when a child under 15 years is suspected of crimes.What happens to the child from an agency perspective? How is the experience for the child and how do they get their voices heard? How is the professional perspective for a child when a child is suspected of a crime? What do the various authorities for short-term and long-term measures for the child?We have chosen to do a qualitative study using semi-structured interviews. The study includes six interviews with two police officers, three field secretaries and a social worker in two different municipalities. A medium sized municipality, and a larger community.The people we interviewed think differently about collaboration. The municipality have different workforms.

 The aim of this essay is to examine if the Swedish Major labels are moving towards making their catalogue available on different platforms rather than their traditional distribution of music. The new technology has really stirred things up for the major labels and file-sharing has been a problem for a long time. The labels have a history of fighting new formats instead of embracing them and listen to what their consumers actually want. We have found that the majors now are in the leading edge of music distribution due to technology and that is a first. We have focused this essay on if the consumption of music has changed the distribution of it or the other way around and found that people have changed their ways of consuming music over the years and the labels have always been forced to adapt.

Denna uppsatts är ett kandidatarbete på programmet för Fysisk Planering på Blekinge Tekniska Högskola och omfattar 15 hp. Uppsatsen genomförs under utbildningens tredje år. Uppsatsen undersöker hur problem och konflikter med konflikter vid hantering av olika sorters trafiksystem på samma plats har skapat en problematisk trafiksituation i Bergåsa. Vilka aktörer som bidragit till att dessa konflikter uppstått undersöks, och hur dessa aktörer även begränsar platsens framtida utveckling. Detta genomförs genom en teknisk och historisk studie av platsen, kopplat till en analys av aktörernas påverkan på processen.

Traditions are something that is very important to many people, Christmas is usually no exception. Christmas tree, Christmas ham, herring and candle lights are just as important as the advent candlestick. The advent candlestick help you get the Christmas feeling during the countdown. In this report the work with a new advent candlestick concept can be followed step by step.A lot of information was needed in the beginning. By doing some research, surveys and interviews the ground was established for further work.

Den här uppsatsen försöker besvara frågan om hur man kan förmedla känslor, tankar och stämningar till människor med trädgården som medium. Uppsatsen söker även svar på om man specifikt kan designa gröna miljöer som riktar sig till människor som går igenom ett sorgearbete. Här ges exempel på flera olika designteorier och olika sätt att tänka kring hur man skapar meningsfulla landskap. Därefter presenteras forskning kring hur människor tar sig igenom ett sorgearbete och bemöter känslor av sorg. Uppsatsen tar även upp Appelton?s teorier kring habitat och prospect/refuge och hur människan förhåller sig till rummet. Vad som avgör vår känsla av trygghet och de underliggande mönstren i hur vi läser av vår omgivning. I den avslutande delen av litteraturstudien går jag närmare in på hur man kan skapa helande miljöer för människor som genomgår ett sorgearbete. I uppsatsen ingår även två utformningsförslag som är baserade på den tidigare genomgångna litteraturen kring hur man skapar trygga och helande miljöer.

The purpose of the study was to determine the attitudes of the teachers of Reggio Emilia inspired preschools concerning the science work with children between the ages of one and three, as well as their opinions on how the physical preschool environment and the choice of materials influence their scientific work. The study was conducted in three departments of two different kindergartens. Although both kindergartens called themselves Reggio Emilia inspired, their working methods and their environments differed largely. None of them were originally built as Reggio Emilia inspired preschools. One of the kindergartens strived to design their indoor environment the same way as the preschools of Reggio Emilia are constructed, there for they were setting up different stations where the children themselves have the opportunity to explore various scientific areas.

Syftet med denna studie var att undersöka vad stress innebär, hur det upplevs och orsakas inom Räddningstjänsten, samt hur det kan förebyggas. Enkäten gjordes utifrån ett kvantitativt perspektiv och skickades till larmoperatörer och brandmän på Räddningstjänsten. Enkäten besvarades av totalt 33 respondenter. Deltagarnas ålder togs inte i beaktning, enbart antalet år av yrkeserfarenhet. Datan analyserades I SPSS, med hjälp av ett Chi-tvåtest och ett Pearsons's r-test.

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

Over the past 40 years 600 000 ha of lodgepole pine (Pinus contorta ssp. latifolia (Engelm.) Critchf.) has been planted in Sweden (280 000 ha on SCA's forest land alone which represents about 15% of the company's total forest land area). In the early 70's SCA situated a number of experimental stands in order to investigate different aspects of the exotic tree, primarily growth rate. To be able to compare the two species plots with scots pine (Pinus sylvestris L.), this species was also planted at the same time and under the same conditions. A number of questions should always be raised when exotic species are introduced in an ecosystem. Invasiveness, the pathogen situation and purely ethical issues should be discussed.

Bildtraditioner, ämnesintegrering och elevperspektiv är viktiga ingredienser i denna C-uppsats. Undersökningen tar sin plats på en gymnasieskola som arbetar ämnesintegrerat, KF Gymnasiet, där jag själv är bild- och medielärare. Jag har valt att följa eleverna i en projektgrupp genom deras arbetsprocesser i ett ämnesintegrerat filmprojekt. Genom intervjuer och enkäter har eleverna fått berätta om sina uppfattningar om bildämnet; ett material som sedan bearbetas genom diskursanalytisk metod. Jag har arbetat med eleverna med både teckning och måleri, för att sedan ämnesintegrera bild med svenska och engelska i ett filmprojekt.

A change towards using more biofuels than fossil fuels is taking place in Sweden, and in many other parts of the world. This makes the use of fuel pellets increasingly popular, causing a greater demand for sawmill sawdust products. There is a trend towards the use of multiple types of shredders, instead of a single type in each sawmill. The purpose of the study was to characterize the different flows of saw particles that can be found at Sävar såg when cutting thick or thin wood with different cutting techniques. The saw particles size, shape, moisture content and heat value were analysed by the cutting stations: first cutting fast and slow, second cutting fast and slow, grading fast and slow and planning.
