Trä och fukt ? Mätmetoder för fuktrelaterade dimensionsförändringar hos trä och deras användbarhet, med två fallstudier inom konservering
This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for hygroscopicmaterials. To know how a wooden object actually reacts to changes in the surroundingenvironment requires methods that involve the object itself. Because of the wood anisotropy,differences in wood structure, finishes and other restraints, it is not always possible to predict themovements.This paper addresses various measurement methods, primarily methods that have been testedin the field of conservation, with examples of their use.
Experimentell undersökning av provkroppar för trälimfogar
This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.

Åkertistel : biologi och icke-kemisk bekämpning
A growing problem in Swedish herbicide free agriculture, the Canadian thistle has been the object of several new trials, seeking methods for non-chemical weed control. The new trials have mainly confirmed earlier experiences; that the most successful methods of control are springtime ploughing, repeated cutting and competition from a stout crop. Row hoeing has also been proven effective. As opposed to earlier recommendations, half season fallow has shown to be a risky and often ineffective method of control. Trials regarding biological methods have shown that above others thistle rust (Puccinia punctiformis) may have the potential of controlling Canadian thistle the future.

Undervisning i media : med fokus på elever med läs- och skrivsvårigheter
This paper is based on observations made in the classroom, interviews and studies ofliterature.The observations that I made during my practical training period made me believethat pupils with writing and reading problems succeeded more often with the methodsof teaching used in media education than with more traditional teaching methods.Through this study I hope to specify and define the factors that were the reasons for this. In doing so I wanted to show that you could adapt the teaching methods to reach more pupils with different kinds of learning styles.I have come to the conclusion that the following factors made the pupils with writing and reading problems succeed more often in subjects related to media education:Variety, time spent, the pupils? interests and the equipment used..
Gemensamma åtgärder i harmoni? : En beskrivande fallstudie av regional miljöpolitisk koordination mellan nationell och internationell nivå.
The aim and scope of this study is to describe the coordination of joint efforts concerning chemicals and hazardous substances in the Baltic Sea region, between the Swedish Chemicals Agency (KemI) and the land-based pollution group of the Helsinki Commission (HELCOM LAND). Based on the description of the coordination, the second aim is to discuss the consequences for the Swedish Chemicals Agency in its policy shaping work towards a nontoxic environment. A qualitative and descriptive case study method is used for this purpose. Theories of coordination and achievement-inducing criteria for environmental goals are applied to the case. Components and related processes of coordination are applied to the descriptive part of the study, whilst the achievement-inducing criteria are applied in the discussion.

Flockning och förtjockning i High-Rate-förtjockare ? en jämförelse med konventionell förtjockarteknik och lamellsedimentering.
In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.
