The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

Syfte och frågeställningarSyftet med studien var att undersöka för elitorienterare resultaten vid och korrelationen mellan ett så kallat 5 minuters pyramidtest (5MPT) och ett maximalt test för bestämning av maximalt syreupptag (VO2max) på rullband. Frågorna vi ställde oss var: Vilken korrelation föreligger mellan 5MPT och ett bestämt VO2max på rullband hos elitorienterare? Hur ser en jämförelse ut mellan uppmätt samt beräknat VO2max? Vilken är reliabiliteten för 5MPT? Hur ser ekvationen ut för att beskriva sambandet mellan dessa två olika maxtester?MetodI valideringsstudien deltog 16 elitorienterare (6 kvinnor och 10 män) i åldrarna 17 till 37 år. De två testerna som genomfördes var 5MPT och bestämning av VO2max på rullband. 5MPT är ett skytteltest som är fem minuter långt, där testpersonen (tp) tar sig fram och tillbaka mellan två stolpar (sträcka 5.5 m) där en vertikal trappa (formad likt en pyramid) passeras under varje vända.

This report discusses questions concerning wear on forest roads. The purpose of the work is to investigate if the wear on the roads will decrease when the speed limit gets lower for the trucks that transport the wood. A normal forest road, class B, was used in the study. In total 5000 m3f timber was transported on the road. Data about the road was measured with a profilograph car before and after the timber transport.

AbstractAim: The aim of this study was to investigate if treatment with ?dry needling? in myofascial triggerpoints (MTrPs) in the rotatorcuff muscles may affect impingement symptoms such as pain during provocative tests, shoulder mobility, and function. The research questions were: Does the value of pain change on the Visual Analog Pain Scale (VAS) between before and after treatment? Do the positive provocative tests for impingement change between before and after treatment? Does the active shoulder mobility change between before and after treatment? Does the self-rated function change between before and after treatment?Method: The study was a prospective randomized intervention study and 19 persons with impingement symptoms (mean ± standard deviation; 58 ± 18 years, and shoulder pain duration 3.9 ± 1.6 months) were randomized into two groups. The groups were tested before, directly after and 3 weeks after treatment.

My aim in this case study has been to create a method for creature design to test this method in a production and evaluate the results. To achieve this I studied and analyzed the methods of three concept artists and illustrators named James Gurney, Neville Page and Iain McCaig. From the analysis of these artist´s methods, combined with my own personal experience, a new method was formed. To test this method a creature was designed based on directives given by a game design group in the process of creating a table top role playing game in a fictitious world. These directives where given for the creature´s role and its living conditions.

To fit into our society the dogs of today need a good mentality. To investigate their mentalitydifferent behavior tests have been developed. The tests are useful tools in the selection ofbreeding animals as well as for working and companion dogs. To counter the demand for atest that could be suited for all kind of dogs, regardless of their future function, the mentalitytest Beteende- och personlighetsbeskrivning hund (BPH) was developed. BPH consists ofseven subtests that expose dogs to various situations that can be found in everyday life, suchas meeting an unfamiliar person, sudden noises and suddenly appearing objects.The aim of this study was to find out if there are differences in physiological values betweenindividuals, validate the behavior observations during BPH and get aware of how the dogsexperience the situation.

Natural monuments are natural objects with special protection due to their high natural value or cultural significance. The natural value is determined by the occurrence of signal species found on and near the natural monument. The law surrounding natural monuments has evolved a lot since the first ones were declared, and today the title natural monument can be replaced with the title tree with high conservation value. The title has come later and can sometimes overlap natural monument. Some natural monuments lack the qualities required to be classified as a natural monument or a tree with high conservation value, but have a cultural importance.

The purpose of this study was to examine the relation between the Big Five personality traits Extraversion, Agreeableness and Neuroticism and the five conflict styles developed by Thomas-Kilmann: Accommodating, Avoiding, Compromising, Collaborating and Competing. The participants consisted of 128 students of the Linnaeus University in Växjö. A questionnaire consisting of two parts were used for this study: Part one consist of a personality-test developed from Lewis R. Goldberg?s Big-five scale, and part two where the participant is asked to fill out Thomas-Kilmanns conflict style test.

AimThe aim with this study was to acquire knowledge of mental training and if you can use it in the elementary school to increase in a short period of time the performance in a coordination test. Furthermore we wanted to investigate teachers understanding of the possibilities to perform this kind of training in the elementary school, and if there is support for this in the school regulation.MethodAs method we have used a combination of a literature pre-study, interview and at the end an experiment. Before the experiment and interviews could take place we studied literature about mental training to get a basic knowledge of the subject. The facts we learned from our pre-study and interviews gave us the base for our experiment. The experiment group included 23 pupils in a third class at school situated in Stockholm.

Syftet med vår uppsats var att undersöka spridningen av COSO-modellen i de svenska kommunerna, och vilka som är idébärarna av modellen. Även korrelationen mellan implementering av modellen och kommuners politiska, geografiska och storleksmässiga placering belyses.Då undersökningen bedrivs inom kommunal kontext har studien en institutionell ansats, och teorierna som används för att kartlägga spridningen av modellen i kommunerna är NPM, Institutionell teori och Spridningsteori. Undersökningen genomfördes med en webbaserad enkätundersökning, och vår målpopulation var Sveriges kommuner. Svarsfrekvensen på undersökningen blev 68%.Empirin analyserades med hjälp av Mann- Whitney test och Chi- Square test, med en signifikansnivå på 5%. Vårt resultat visar att det finns ett samband mellan spridningen av COSO och kommuners invånarantal.

Stroke är en av våra stora folksjukdomar. Cirka 30 000 personer insjuknar årligen i Sverige. Många av dessa personer får även droppfot. Peroneusstimulering började användas för första gången 1961. Tekniken är nu generellt känd som Funktionell Elektrisk Stimulering (FES).

Since 2005 all companies listed on a regulated stock exchange within the European Union are required to present their financial reports in accordance with International Financial Reporting Standards (IFRS) and International Accounting Standards (IAS). The purposes of these standards are to accomplish international harmonization of accounting rules to make financial reports more comparable. However, recent research has shown that some firms tend to use goodwill strategically in a business combination by manipulating the acquired assets and consciously allocate the intangible assets to goodwill to reduce the depreciation in the income and decrease costs. This phenomenon may reduce the comparability between financial reports and thus has an opposite effect on the purpose of IFRS and IAS.The aim of this study is to show how the companies involved in this study allocate goodwill strategically. Furthermore, the introduction of the new standards has contributed to that goodwill now is a subject for impairment test, therefore we want to show whether this affected the comparability of the companies in this study.An empirical study was conducted, based on interviews with four Swedish managers.

Wood pellets are an upgraded product of residuals from several wood processing industries, for example saw mills and pulp industries. The pellets are produced by pressing the milled and dried sawdust to cylindrical units with a higher density than the initial raw material. Pellets have great benefits compared to the raw material: high energy per volume, good transport and storage properties and homogeneity. Several parameters collaborate in the whole process, which makes it complex. Wood is a heterogeneous material, chemically and structurally dependent on wood parts, habitat and storage procedures.
