Tillämpning av nya beräkningsmetoder för branddimensionering av  träkonstruktioner - analyser och jämförelser

To build high-rise buildings made of timber has for long been limited by national laws, due to the lack of knowledge in engineering solutions. Frame structures made of wood has for a long time been associated with major fire hazards and consequently lower safety and this connection is still being made today. The increased environmental awareness in recent years has contributed to the exploitation of indigenous building materials, including wood from our own Swedish forests and has become increasingly common. Increased knowledge about how structures behave in fire and how they can be protected in order to achieve safe timber structures has resulted in a growing interest in these structures in the construction industry. Research in the area is constantly updated and new laws allow any number of storeys in wooden buildings in Sweden as long as the performance requirements are fulfilled.The main part of this work has involved calculations of the fire resistance and load bearing capacity of floor and wall constructions.

Detektor på skördare för utsortering av träd med metallskrot

Fortifikationsverket which is the landlord for the Swedish national defence has a great problem in their forestry due to the relatively large amount of metal objects in their timber. These metal objects cause different types of economical losses in the timber refinement chain. To enable out sorting of logs containing metal objects already in the harvesting phase, Fortifikationsverket is interested of the possibility to utilize some type of metal detector in a harvesting head for that purpose.The goal of this study was to, with help of a case study, enlighten the problem that metal objects in timber cause for Fortifikationsverket and their customers of timber and to investigate conditions of to mount and utilize some kind of metal detector in a harvesting head at present.The saw timber deliveries by Fortifikationsverket during the time period 2003-2005 was used as a reference volume for calculations of economical losses. In this case study was included two sawmills where timber from Fortifikationsverket were delivered to for further refinement. Factors investigated were the type of damage metal objects caused in these two sawmills and the economical signification of these damages.

Effektiv intern kommunikation : En studie av kommunikation mellan värdar och värdledare i en idrottsförening

AbstractTitle: Effective internal communication ?A case study on communication between a manager and the employees in a sportsclub.Number of pages: 40, without enclosuresAuthor: Susan AnderssonTutor: Peder Hård af SegerstadCourse: Media and Communication Studies CPeriod: Second term 2005University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: I aim to do a case study of a work situation, where there is no natural or direct form of feedback between the manager and the employees, and compare the purpose of the information efforts with how it is perceived by the employees.Material/Method: Qualitative research method, including an assembling method in the form of interviews, and a processing method of those interviews.Main results: All the used channels combined together (except one channel) seem to have created the right condition so that the content of the information can be perceived and used as the way it was supposed to, even though there?s no direct feedback of the information.

Taxes and Human Capital as Determinants of Foreign Direct Investment in EU: The Role of Most Favoured Nation Treatment

Summary Title: Taxes and Human Capital as Determinants of Foreign Direct Investment in EU: The role of Most Favoured Nation treatmentAuthor: Andreas HelmerssonSupervisors: Cecilé Brokelind and Rikard LarssonProblem discussion and problem Formulation: The recent year?s rapid increase in foreign direct investment (FDI) is a clear indication of increasing globalisation. In order to stay competitive companies must take advantage of talented people, new technology and new markets around the world. Not only companies but also countries and regions, such as EU, need to take advantage of globalisation and the advantages that come with the increase in FDI around the world. Studies have shown that FDI does not only make companies more competitive but it also stimulates the economic growth of the region where the FDI takes place.

Förändring som styrmedel  : En studie av implementering av nya rutiner på IKEA Örebro

This paper aims to study the Armenakis´ theory of readiness, "are they ready?", which consists of five key components affecting the outcome of an organizational change. In this case study, the intention is to investigate if any component is important; alternatively if it is possible to discern a pattern between components, i.e. how they correspond to each other. During the past 30 years have a research group lead by Armenakis has studied organizational change and how resistance to change can be avoided by preparing employees in the introductory phase of change. The main object for Armenakis is the question "what determines whether the employees (change recipients) adopt and support, or reject and resist a change".

Total Risk Classification

Ett företag med ett flertal leverantörer måste på sikt välja ut vilka leverantörer man önskar arbeta aktivt/passivt med. För att kunna göra detta krävs att man tar fram konkurrenskraftiga leverantörsstrategier som bygger på välgenomtänkta beslut. Dessa beslut måste ta hänsyn till inköpets totala risk för leverantör och komponent. Den totala risken är oftast väldigt specifik för varje företag och bygger på ett flertal olika parametrar. Författarna ger i denna uppsats förslag på tre parametrar som kan hjälpa företag att ta fram effektiva leverantörsstrategier.

Strålbenshälta hos häst - vilka är de genetiska faktorerna bakom detta hälsoproblem?

Denna litteraturstudie behandlar strålbenshälta hos häst, även känd som Navicular disease (ND). Studien beskriver sjukdomen och dess karaktäristiska drag, samt belyser de två huvudsakliga teorierna om den bakomliggande orsaken till insjuknandet. Det finns tydliga inklusions- och exklusionskriterier, vilka är viktiga för att kunna göra en omfattande hältutredning och för att kunna ställa rätt diagnos, som är betydande för att ge rätt behandling. Litteraturstudien belyser även det faktum att hästar drabbade av ND har visat sig ha högre intramedullärt tryck i strålbenet, samt vilka genetiska riskfaktorer som visat sig vara kopplade till sjukdomen. De genetiska defekter som behandlas är röntgenförändringar i strålbenskonturen (RAC) och strålbensstrukturen (RAS), samt utvecklandet av deformerade näringsfåror i strålbenet (DCS).

Frigörelse av fosfor från färskt, fryst och torkat växtmaterial : ett laboratorieförsök för att öka förståelsen för fosfordynamiken inom växtodlingen

Phosphorus is the single most potent contributor to eutrophication of freshwater and has also been shown to contribute to the toxic algae blooms in the Baltic sea. The dynamics and paths of losses of phosphorus from arable lands are not fully understood. It is known that phosphorus can be lost directly from plant material to water. In studies where plant material has been subjected to several freeze-thaw cycles, large amounts of phosphorus have been lost. Most studies have been conducted under field conditions, with many factors effecting the measured losses of phosphorus, such as weather and type of soil. This study was performed in a controlled environment without the presence of soil. Instead of soil, small glass beads were mixed with the plant materials in vessels, to make possible homogeneous leaching with water through the mixture of glass beads and plant materials. In this study, clover, ryegrass and dry straw were cut to pieces, approximately 2 cm long.

Dragbrotschning av invändiga profiler

High-precision cutting in metal is very complicated, a lot of parameters affect the result: what geometries to be manufactured, surface roughness and tolerances to be achieved, batch size etcetera. When pull-broaching internal parts this might be even more important, than in any other cutting operation. Everything is machined in one single stroke and the general technology is built in to the tool, therefore big investments must be made to change the process. Milling for an example: one piece at a time is machined away, and a lot of parameters can be changed easily.It is very high pressure on the cutting-edge when the broach is cutting. To achieve the specified product and to avoid unnecessary toolwear it is essential to use the right cuttingfluid and the right cuttingspeed for an example.

En jämförelse av sitkagranens (Picea sitchensis) och den vanliga granens (P. abies) produktion :

Sitka spruce (Picea sitchensis) is a tree species that have its natural distribution along the West Coast of North America, from Alaska in the north to northern California in the south. Sitka spruce is a typical coastal tree species that can reach heights up to 85 meters and occurs in single pure as well as in mixed stands. The main purposes of this study were to describe the Sitka spruce growing characteristics and the volume production in comparison to spruce (Picea abies). The possibility to predict future volume production by using prognosis tools designed to be used on spruce were also studied. The material that has been used in this study are permanent sitka trials established by the Faculty of Forestry fixed Sitka trials and also material gathered in this study. A literature study was also carried out in order to determine the Sitka spruce growing characteristics. Sitka spruce has a high adaptation and a high volume production on a broad scale of soil types. The tree species is a pioneer species that has a fast early growth and in combination with sharp needles it is less susceptible to animal browsing than spruce. The factor that is the single most limiting factor for where the Sitka spruce can be planted is frost. This factor can be limited by using plant material with a well-suited provenance. According to the literature, the Sitka spruce has an average total volume production that is between 20-40% higher than spruce.
