The Swedish Cellulosa Companiy, SCA, has today 280 000 ha planted with lodgepole pine (Pinus contorta var. latifolia) (?C?) which is equivalent to 14 % of its total forest area. Exotic lodgepole pine has in previous experimental stands shown a superior growth than the native Scots pine (Pinus sylvestris L.) (?S?).But also the comparison could be questioned because stand histories were was unknown and also differences in age between C and S existed.

SammanfattningLångvarig smärta orsakar stort lidande för individen och belastar samhället ekonomiskt. Syftet med denna uppsats var att undersöka om en exponering in vivo-behandling inspirerad av Dialektisk beteendeterapi (DBT) för människor med långvarig ländryggssmärta var görbar samt om behandlingen gav effekt på smärtrelaterad problematik. Designen var en single case experimental design vilket är en beprövad design för att testa nya terapimetoder. Studien bestod av sex deltagare, alla med hög grad av smärtrelaterade katastroftankar, något som litteraturen visat predicera sämre behandlingsutfall. Behandlingen var DBT-inspirerad och indelad i tre faser; en första valideringsfas, en andra färdighetsfas och en tredje exponeringsfas.

Studies indicate that between 6-9% of all children has some type of voice problems. Voice problems in children may have different etiology and can affect all ages. In Sweden, there is a lack of a standardized questionnaire addressed to children with voice problems and their legal guardians. The purpose of this study was to translate and validate the Pediatric Voice Handicap Index (pVHI) in Swedish children aged 6 to 10 years. The study was carried out through an internet-based assessment form for children referred to speech and language pathologist/ phoniatrican due to voice disorders in Sweden and a matched control group of children without voice problems.

 AbstractThe aim of this essay is to look into how teachers view pupils who use finger arithmeticduring mathematic classes. How do these teachers help them to move on with their learning,what information and problem-solving material do they use?I made qualitative interviews with grade two- and grade three teachers, in three schools.The interviews showed that the teachers find it difficult to adopt a suitable attitude towardsfinger arithmetic. In addition, lack of time for planning and lack of knowledge about variousexperimental methods caused further predicaments. The teachers were aware that arithmeticexperimental material was attainable at the schools, but time to learn about it and how to useit was lacking.

????The aim is to examine how written production differs between students with and without difficulties in writing. The study also examine how different difficulties within writing interplay. It is based on analysis of ten-year old student texts with 30 texts from both an experimental and a control group. Texts were written in 1991.Both spelling, technique of writing and syntactic complexity differ between the groups.

This project was initiated by a desire to improve our knowledge about animal welfare. It is a part of a series of projects involving the way dogs are kept in today?s society. The aim of this project was to investigate the dog?s behaviour when left alone in a parked car.

Lättelement located in Örnskoldsvik AB is one of Sweden's leading companies in the development of building elements in the form of roofs, walls and floors made ??out of light beams. The company has clients from Lund to Kiruna, and from Norway. This means that the elements have high standards when they have to take many different loads from wind and snow due to such wide geographic variation.The roof elements are structured so that the main body is made of light beams with an I?profile.

This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

The current study aimed to test the public self-consciousness impact on creative performance. An experimental design was used in which 40 participants were randomly assigned to two groups, one of which was the experimental group and the other was the control group. A mirror was used in the experimental group to induce public self-consciousness among the participants while they performed creativity tests. A consequence test was used where the participant had to give suggestions for the given scenario "What would happen if everyone became blind?" which was then measured in the number of proposals (fluency).

The purpose of this study is to investigate whether intensive teaching of reading strategies at an individual level can affect reading comprehension for students in second grade. A quantitative method with quasi-experimental design is used. All students in the experimental class trained on reading comprehension strategies at their particular level five times each. Before and after training a reading comprehension test was made. The reference class did the same test.

At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.

The purpose of this Masters thesis is to examine the performance of queries that are expanded by synonyms and hyponyms from Svenskt OrdNät, the Swedish version of the Princeton WordNet. Four different types of queries were constructed: a baseline query S1, the baseline query expanded with synonyms S2, the baseline query expanded with hyponyms S3 and finally the baseline query expanded with the synonyms and hyponyms used in S2 and S3. The terms for expansion were picked by hand. The queries were executed in the Query Performance Analyser QPA, a tool used in IR education and in experimental IR research for analysing and comparing the performance of individual queries. 20 topics from the test collection GP_HDINF were chosen for the experiment.

This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.
