Sitkagranens potentiella merproduktion jämfört med vanlig gran i Hallands län
Sitka spruce (Picea sitchensis) is not considered to be a native species to Swedish forests. It´s origin is the pacific coast of Northern America, an area that is dominated by a coastal climate which makes it likely to believe that it would be well suited for growing in the south-west of Sweden.
This study aims to investigate the gain in production that can be reached by growing sitka spruce instead of Norway spruce (Picea abies) in the county of Halland. A regression model based on data from forest experiments was produced to explain the gain in production. This model was based on elevation and annual precipitation.
The model was then used to create a map layer in arcGIS that shows the gain of volume in comparison to Norway spruce in percent. An analysis was carried out to find what share of the forestland in Halland county that fell into four different classes of production gain.
Alternativ till fortsatt elektrisk generering i Olidan
In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.
Inverkan av olika joner och jonconcentrationer på porstorleksfördelningen i trämassa-fibrer
The basic ingredient of paper is the individual wood fibers. The property of the fibers depends on a variety of factors e.g., method of pulp production and processing. The final sheet quality depends in part on how the fibers interface between each other and therefore factors that affect the fiber size are of interest.The flexibility of the fibers depends in part on the pore water i.e., the fiber swelling. The sheet becomes less flexible at low water content which gives a loss in strength. Thus it becomes desirable to increase the water uptake.The experimental investigation described in this report consists of exposing the wood fibers to different ions and ionic strength and then measure the pore size by thermoporosimetry where a DSC (Differential Scanning Calorimeter) is used.
Medveten måltid : Ett begrepp i förändring
The key elements of sourdough fermentation are the presence of active lactic acid bacteria (LAB) and yeast. Sourdough fermentation originates from the ancient Egypt. One theory concerning its onset states that a portion of bread dough was set aside to be baked at a later date and started to ferment spontaneously.Sourdough may contain a wide variety of microorganisms, mainly dominated by LAB and yeast. There are over 50 species of LAB that has been identified in various sourdoughs and more than 20 species of yeast. Sourdough fermentation has been shown to have various impacts on baked cereal good, most of which are attributed to LAB.This study addresses some effects of LAB from fermented milk products in sourdough and sourdough bread.
Den svenska monarkin - Ett försvarbart statsskick En normativ analys av den svenska monarkin och en innehållsanalys av tidningsartiklar om Bruneiaffären
Although Sweden has democracy implemented in its Constitution, because of being a monarchy, it has a non-elected Head of State. The purpose of this thesis is on the one hand to show if it is possible to normatively legitimate the Swedish monarchy and on the other hand to display if and how the three biggest Swedish newspapers Aftonbladet, Dagens Nyheter and Expressen justify monarchy by making a content-oriented analysis of their coverage of King Carl XVI Gustaf's political statement during his state visit in Brunei 2004.By using consequentialism and deontology as perspectives I will show that it overall is not possible to normatively justify the Swedish monarchy compared to a Swedish republic with an elected Head of State. This is mainly because democracy is implemented in the Swedish Constitution. In all three newspapers there is only little debate on the Constitution. Most commonly journalists criticize the King's statement but not monarchy as an institution.

Historiesyn - Drivkraften i försoning : Ett kvalitativt arbete av Commision on Amnestys historiesyn
Title: Festivalernas Intåg ? Korröfestivalen- en bordunstämmas resa genom festivaliseringenThe Korrö festival- The establishment of a Swedish Folk Music Festival.This thesis describes how folk music festivals have been escalating during the past few and how they have influenced Swedish folk music. To reach my results I have been studying one festival in particular which is the Korrö Folk Music Festival. This event started in the mid-eighties as a small happening that attracted almost exclusively musicians that were a part of the bordooon movement. The bordoon movement gathered a couple of days in the summer at what they called the ?Korrö bordunstämma? to build instruments and play folk music.

Sinnesmarknadsföring : Ett effektivt verktyg för folkbibliotek?
Sensory marketingAn effective instrument for libraries? We are living in a world of constant communication and information and because of that, marketing in general seem to have no distinctive effect. Consumers become overwhelmed by all the advertising messages. Due to this, it is clear that organizations like libraries must create a deeper and more personal connection to increase user satisfaction and foster the use of services, among both users and potential users. One way to achieve this is to make use of all the emotional elements of a product or a service.

Att katalogisera en specialsamling med hjälp av TEI: En metodprövande studie utförd på Swedenborgsarkivet i Kungl. Vetenskapsakademien
In this thesis, the TEI (Text Encoding Initiative) encoding scheme is investigated as a system for storing metadata about manuscript material and 18th century first prints in the Swedenborg Archives at the Swedish Royal Academy of Sciences. The aim of the study is to test the functionality of TEI as a metadata system in cataloguing a special collection. Some criteria of functionality are formulated, and examples of encoded catalogue entries are described and analysed. It is demonstrated how descriptive metadata have been registered within the TEI header, while structural metadata have been recorded within the text element of the TEI file. On the whole, TEI is considered to be a functional tool that matches the present purposes.
Kunskapsspridning inom projektbaserade företag
Background: Society of today is characterised by greater dynamics and a constant demand for innovation and fresh ideas. This development is often named "the new economy" or "the knowledge society".
