Since the end of the eighteenth century forest damage caused by the pathogen Gremmeniella abietina has been observed and documented. During the latest epidemic in Sweden more than 480 000 hectares forest land have been injured and this has lead to considerable economic losses. For the pathogen to succeed with infection, spore dispersal and colonization the right environmental conditions is required. The aim of this paper is to describe the diseased stands using site and stand characteristics and to evaluate the effect of these variables on the disease incidence. Further, the thinning performed during the time for spore dispersal and its relationship to injured stands is examined.

Bakgrund: Den logistiska kedjan från producent till konsument blir alltmer komplex på grund av att ett ständigt ökande antal artiklar tillverkas utifrån kundens behov och önskemål. För att kunna tillgodose dessa behov och önskemål har företag historiskt sett haft stora lager. VMI tar problemet med att hantera och utveckla effektiva lager till en ny nivå. Att arbeta med VMI innebär stora fördelar för många olika företag när det gäller informationsspridning, partnerskap och lagerföring. Trots de omfattande fördelar som beskrivs i de flesta teorier om VMI finns det en del framförd kritik.

This is an essay concerning the density of the city. An increasing amount of today?s cities have a shortage of space available for the erection of new buildings and settlements, especially in areas close to the city-centre. New buildings and settlements are therefore often found in the outskirts of the city, resulting in long distances between work and living for many people. These long distances are a waste of limited resources and are inconsistent with the vision of the sustainable city.The challenge for the future is to insert new buildings and settlements in the existing city-structure and in this way reduce the distances between different city-functions.The density of the city can be increased in two different ways; by inserting new buildings between existing ones or by extension existing buildings, for example by an additional floor.

Today green tree retention, together with leaving dead wood, is a common practice with the aim to reduce negative impacts on biodiversity and environment due to clear-felling. To better understand whether this conservation practice also makes a long-term difference, it is important to know what happens to these trees after harvest. Few studies have made an assessment of what happens to retention trees over a longer time period. In this study I inventoried retention trees that were left at clear-cuts six, twelve and eighteen years ago. I carried out a re-inventory of 57 retention patches (divided into free-standing tree groups, small swamp forests and edge zones) and free standing dead trees, spread over 25 previous clear-cuts in central Sweden.

There are plenty of exciting changes being developed in Tre Högar´s Park, which is located in the district of Linero, eastern Lund. A project group representing Linero If, Lugi Tennis and Linero/Östra Torn Health centre, has been created and is responsible for managing a development project of the Park. Their main focus is to create sports, exercise, health-promotion, health-care, recreation and rehabilitation facilities. They view the park area as having great potential and will transform it into a purpose built park for Health and Exercise. There are various authorities involved with and engaged in the scheme; aside from the project group, the municipality of Lund, The sport association of the handicapped and local schools are being consulted.

Facebook är ett socialt nätverk som gör det möjligt för medlemmar att presentera sigsjälva genom en profil som andra kan ta del av. Syftet med undersökningen var attstudera dels huruvida introverta personer är mer känslomässigt engagerade i Facebookän extraverta personer, dels huruvida personer med lägre självkänsla än genomsnittet ärmer känslomässigt engagerade i Facebook och dels huruvida introverta personer medlåg självkänsla är mer känslomässigt engagerade i Facebook än andra personer.Undersökningen omfattade 117 respondenter från utbildningar tillhörande densamhällsvetenskapliga institutionen. Undersökningen baserades på Facebook intensityscale, på NEO Five-factor Inventory (NEO-FFI) och på Rosenbergs (1965) self-esteemscale. Resultat visade att extraverta personer med låg självkänsla är mer känslomässigtengagerade i Facebook..

Objective: The aim of the study is to describe pupils' understanding of the mathematical concept of function. How do pupils define the concept of function? What images of the concept of function evoke when they solve tasks, which involve identifying and constructing functions?Theory: A student's thinking about a mathematical concept depends on more than just the formal definition of the concept; therefore Tall and Vinner introduce the term concept image to describe the role cognitive structures play when students learn about concepts. The cognitive structure includes all mental images, associated properties and processes that an individual associates with a given concept. According to Sfard, an individual's understanding of mathematical concepts may have different character: an operational conception, where a concept is conceived as a process and a structural conception, where the given concept is conceived as an object, that is, as a whole.Method: 16 pupils at the Science Program at two different upper secondary schools inSweden answered a questionnaire on the mathematical concept of function.

In this thesis a method for evaluating investments in small scale hydro power is presented. An analysis of the future position that small scale hydro production will have on the Nordic electricity market is also carried out. This is done by an inventory of technology and economic and environmental aspects. The inventory is also a guide as to how the project should be implemented.Hydrolyzer is the name of the Excel tool developed to evaluate investments. The tool requests input data from the user and then evaluates the investment and generates a sensitivity analysis.

We came in contact with the project "Grönplan Danderyd" that aims to create a green structure plan for a municipality of Stockholm called Danderyds kommun. Our thesis is a part of this project and makes it's contribution through the gathering and systematization of the knowledge of the functions of an urban green structure. It also makes a contribution through suggesting how this knowledge can be applied during the construction of an urban green structure plan. We found that "Stadens parker och natur", published by the Swedish National board of Housing, Building and Planning, was a recurrent source of information in the green structure plans that we studied. We saw a need of complementary additions and updates to the rather old report and found literature that adds the developments of the last decade. First of all we have chosen to make themes based on the functions of a green structure that were presented by 'Stadens parker och natur'. The themes we suggest that a greenplanning document manage are: Recreation, Pedagogies and Heath, Biological Diversity, Green structure in the History of Building Cities, Cultural Identity, the Health of the City, Biological Technology in the Municipality and Use and the Users. We found good examples of how to handle these themes in documents that handle greenstructure planning from the municipalities of Göteborg, Strängnäs, Eskilstuna, Malmö, Lund, Västerås and Uppsala.

This thesis is a discourse analysis analyzing public library librarians' talk on the subject of public library meeting places. Within the field of Library and Information Science the public libraries' functions as social meeting places have been scrutinized for more than a decade. Researchers in the Nordic countries in particular have looked at library users' use of the library space and have highlighted the sociologic dimensions of the public library and the meeting place functions. Few however have paid much attention to the library personnel's point of view. The discourse analysis perspective is about language use and how people construct the reality.

This report explains how different communication tools can be used in a company?s intranet. It gives a short description of the different parts in an intranet and their field of application, and what communication means. It?s only the communication tools that the company uses that we are illuminating in this report.

Social fobi är en av de vanligaste ångestsjukdomarna. Rädsla och oro i sociala situationer och prestationsrelaterade dito är utmärkande för dessa individer. Social fobi tenderar, om den inte behandlas, att bli kronisk och det finns indikatorer på att tillståndet förvärras över tid. Idag finns behandlingar som ger goda utfall direkt efter avslut, men huruvida behandlingseffekterna håller i sig över längre tid är mer höljt i dunkel. Internetadministrerade självhjälpsbehandlingar har en möjlighet att öka tillgängligheten för denna klientgrupp och det är då av vikt att den är av god kvalitet.

Stress and burnout is a common healthproblem among different workcategories today. The aim of this study was to investigate possible presence of stress and burnout among radiographers and if there was a connection to number of years in the profession. Maslach Burnout Inventory was used as an instrument to investigate the possible presence of  burnout, supplemented with questions about stress. The instrument contained a total of 33 questions and was handed out to two hospitals in south of Sweden with a total of 51 respondents. The study showed that the most stressful situations arose due to workload, negative stress, bad working environment and high time pressure.

This thesis discusses the possibilities to distribute digital video in a military vehicle. Today, an analogue system is used, which has a maximum capacity of eighteen video sources and the same number of monitors. The purpose of this thesis is to increase the systems capabilities regarding secure distribution and additional functions. Both software and hardware tests are made to investigate the features of the digital video standard MPEG-2. Both the coding delay and the image quality are of great interest.
