Den urbaniserade Umeälven : Vattenkraftverken som utsträckt urbanisering

This paper examines the power producing dams along the Ume-river as an integral part of and a result from the urbanization process in Sweden during industrial capitalism. The aim of the paper is to contribute to the knowledge of the urbanization process in Sweden in general and of its traces along the Ume river in the county of Västerbotten in particular. The paper applies the theory of concentrated urbanization and extended urbanization put forward by Neil Brenner and Christian Schmid (2015) and argues that the building of power producing dams along the Ume-river is part of an extended urbanization process. This becomes particularly evident when examining the vast physical structures that is the dams, situated in an otherwise remote and sparsely populated area. These vast physical structures are also very well connected to a nation wide electric grid that has connections to bordering countries as well.

Energianvändning i sjukhuslokaler. Analys baserad på verksamhetsrelaterade nyckeltal

ABSTRACTThe discussions about energy use have increased year by year everywhere in the society, and so also in the healthcare sector. But what is actually energy use in a hospital facility, and what affects it?The typical way today to express the energy use is in kWh/m2. The problem with a key performance indicator that is expressed as energy use in relation to a specific area is that it does not take into account the activity in the building. Even though the activity to a very high extent affects the energy use.

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.

Hur påverkar rörelse barns prestation i skolan?   How does movement affect children?s performance in school? : How does movement affect children?s performance in school?

This report is a qualitative interview study which central content enlightens how movement and sports effects children?s performance in school. With the help of five different teachers in three different schools questions like; how does movement effect the performance of children in school? Have been answered.Lots of research and litterateur shows that children is doing better physical and mental, the concentration level is improved and the performance in school is better when exposed to more movement, also there are less conflicts and the students gets better motor skills.Comparison with the ?Bunkefloproject? has been done, which was a project in the south of Sweden where they let the children have physical education every day and then they examined how this effected their performance in school. With this basis this report will examine the teachers view on the subject.The result shows that the teachers think that there should be more movement in the daily schedule for the children because they seam to be more happy and concentrates better after movement.

Utomhuspedagogik- det outnyttjade rummet

Through a quantitative examination, 26 pedagogies in the pre-school activity answered a few questions in an enquiry about outdoor education. The purpose with this examination was to find out what pedagogies think and apprehend about outdoor education, and also if the "education plan" is in their minds during outdoor activities and if they see them self´s as competent in nature studies. They have also answered questions whether they think that they have good outdoor environment that stimulates children´s development and learning and if there´s any forest that they visit on regular basis.The pedagogies think that during time spent outdoor, it´s the motor skills that are best developed. All of the pedagogies mentioned above think that they need to get more educated in nature studies and also that pedagogies attitude towards time spent outdoors affect the children. They do not think about the goals and intentions of the "educations plan" all the time.

Eurytmi och lärande : Pedagoger och eurytmisters syn på relationen mellan eurytmi och lärande bland förskolebarn

This is a study on how eurythmists/educators describe the relationship between the practice of eurythmy and learning in young children. I wanted to find out what concepts these eurythmists/educators use when speaking of learning in relation to eurythmy. In addition I would also like to explore what eurythmists and educators think that children learn when practicing eurythmy. The method of this study is interviews with two educated Waldorf teachers, as well as two educated and practicing eurythmists, in a fenomenological interview setting with open questions. The theories of Merleau-Ponty, on the phenomenological body, has been used when analyzing the interview material - that is; through the understanding of a physical learning in these theories on the phenomenological body I have tried to understand and analyze the interview material.

Demokratisering i Turkiet - en analys av statens, civilsamhällets och globaliseringens roll i demokratiseringsprocessen

I vår uppsats ställer vi oss frågan varför Turkiet, trots över 50 år av demokratiska institutioner bryter mot mänskliga rättigheter samt yttrande- och pressfriheter. Vi har använt oss av en modell som identifierar tre kärnområden viktiga för demokratisering: staten, globaliseringen och civilsamhället.Vår slutsats är Turkiet har en politisk kultur som inte gynnar konsolidering. Detta beror på flera olika faktorer. Transitionen från diktatur till valdemokrati innebar att strukturer etablerades som favoriserade eliter. För det andra finns det en omfattande partikularism i statsförvaltningen jämte det demokratiska systemet.

Reglering av veka strukturer med multipla sensorer

In this master thesis, control algoritms using arm side sensors are investigated for an industrial robot. The sensors can be position encoders placed after the gearbox and accelerometers on the robot arms. Control strategies are discussed and evaluated for different models of the robot, after which chosen strategies are applied to a realistic model. Control algoritms using arm side sensors (LQ, dual-loop and PD-PID) are compared to a PID-controller that only uses measurements of motor position for feedback control. The comparison are done with respect to disturbance rejection, oscillation damping, robustness and tracking performance of a reference trajectory.

????????????Pedagogers syn på utomhuspedagogik

The purpose of the research is to find out how the teacher of the pre-school looks at the value of the nature Pre-school. To get an understanding of what the nature pre-school enviorment can bring, we are talking about learning, knowledge, and experience combined with the everyday lessons learned from the natural world. The research is a stepping stone on the pre-school teacher?s thoughts and reflections of what a nature pre-school is. This is grounded in a view of how having options for alternative schools lead to wider research, and all conclusions where formed after multiple interviews and analysis.The results showed that the teachers involved are very positive to the nature pre-school environment and learning process.

Normering av en objektiv metod för att mäta käkrörelser med 3D-videoanalys vid tuggning samt en jämförelse mellan käkens rörelseomfång vid tuggning och tuggeffektivitet hos unga vuxna

This study aims at norming a new objective method to track and measure jaw movements in 3D (three dimensional) during chewing in the young adult population (n=41, age 22-30). Norm values of the range of movements and the duration were calculated. Intra and inter rater reliability was high. Masticatory efficiency among participants was evaluated with a two-colored wax, analyzed with picture analysis software. Regression analysis was used to calculate the relationship between movement and duration variables and masticatory efficiency.
