Produktivitet vid stubbskörd :

Stump harvest could be found in the late 1970?s and the early 1980?s. And now when the prices on energy are high it has become an interesting topic again. This work has been conducted within Holmen Skog?s stump harvest testing in Norrköping.

Medborgardialog i ortsanalys : ett arbete om värdet av kommunikation tidigt i planeringsskedet

Citizen participation is fundamental in place analysis, where the aim is to define the sites specific character and identity. The local citizens know the village better than anyone else since they lead their daily life in the environment. I have in cooperation with Sala municipality suggested guidelines on how to involve the local people in dialogue during place analysis. The target was to involve and enthuse as many people as possible with relatively small resources in time and money. The suggested methodology was tried out in a place analysis of Västerfärnebo, a community with about 3 000 inhabitants of which 500 live in the main village.

VSM och 16 förluster

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

Ombyggnad av flerbostadshus : Hur påverkas hyresgästerna av  en ombyggnad

During the years 1950-75 was the construction of building apartments in high speed. A rapidly growing reconstruction requirement is the consequence of the rapid construction speed in these years. The technical lifetime of the different parts of the buildings is about to end and the needs for reconstruction is huge. One of Sweden's national environmental objectives is to reduce the urge of energy in buildings. This calls for radical measures to implement energy efficiency of existing assistance particularly in the assistance that is now facing reconstruction.

PSYKOLOGINS GR?NSARBETE OCH SANNINGSANSPR?K En id?historisk diskursanalys av Psykologtidningen 2010? 2024

This thesis examines the boundary-work between the discipline of psychology on one side and religion and spirituality on the other. In Sweden, a country viewed as one of the most secular in the world and which has a rising interest in the neo-spiritual, this boundary-work is under-researched within the history of ideas. The research question for this thesis concerns how the contemporary dominant discourses in Psykologtidningen between 2010-2024 relate to the historical boundary-work that has taken place within the discipline. In this study the boundary-work will be examined through a combination of digital text analysis and discourse analysis. The analysis shows that terms such as mindfulness and soul have gone through a decoupling process: meaning that the terms are secularized and modernized to fit within the truth-narrative and the leading discourse of psychology. This discourse falls under a larger regime of truth where secular thought is seen as the main worldview which is compatible with the scientific ideal.

Riskanalys av järnvägen genom centrala Halmstad

The purpose of this risk analysis is to investigate if the transport of dangerous gods through Halmstad is a threat to the surrounding area. The report shall serve as a component in the making of pre-plans and the planning of exercises..

Födointagets betydelse för muskelglykogeninlagringen efter arbete hos häst och människa :

Glycogen is the storage form of glucose and is used by the skeletal musculature as energy both for intense and endurance events. The glycogen content in the horse?s middle gluteal muscle is more than 600 mmol/kg dry weight, and almost 400 mmol/kg dry weight in the human?s Vastus lateralis. In some special occasions, for example in competitions with several moments on following days, there is a need of a fast muscle glycogen resynthesis. The feed intake is of importance for the velocity of the resynthesis.

Effektivare energianvändning på Totebo AB

The main goal with this thesis report was to come up with ideas of how to make the use of energy more effective and thus save money for the company.First a survey was made to find out where and how the energy consumers were divided within the company. The results were then used in calculations to find out how much money that could be saved and how long it would take to get back the investments.There is a big potential in saving money by recovering heat from the UV-lamps with a heat exchanger. It would also even out the pressure in the factory which is a source to heat loss and a cause for discomfort amongst the employees. It?s possible to save 105 000 kr in a year and the money needed for the investments is 600 000 kr.By using the recovery air more effectively the company could save up to 250 000 kr a year in lowered heat purchases, but this would require the use of automatic dampers.If you reschedule the running times for the wood chipper and invest in some kind of load management, for example Sydkraft?s ?Energidirigent? you can save at least 42 000 kr.

G2060

I dagens samhälle blir det allt mer intressant att spara energi, dels med tanke på miljön och dels föratt minska på utgifterna. Denna energi ska sparas på ett sådant sätt att effekten för användarna blirså liten som möjligt.I denna rapport beskrivs hur ett reglersystem kan byggas för att minska energiförbrukningen hosväxthus genom att reglera belysningen på ett effektivt sätt. Systemet är helt automatiskt vilket göratt användarna inte behöver tänka på styrningen av lamporna alls när väl systemet är uppsatt ochkonfigurerat.För att styra lamporna på ett bra sätt mäts det inkommande ljuset med en PAR-sensor. Lampornatänds och släcks därefter beroende på ljusmängden och även på hur varmt, eller kallt, det är iväxthusen.Styrningen av belysningen sker med en mikrokontroller från Microchip, en PIC18F4620 som ärprogrammerad i C18. Kringkomponenter som portexpasioner, klocka och reläer användes också föratt bygga ett bra reglersystem.Resultatet är att det är möjligt att bygga ett reglersystem med begränsad budget som styr lampornapå ett effektivt sätt.

I don´t know, I just like it : En studie av ett antagningsarbete på en konsthögskola

This thesis examines how a jury on an artistic education adopts next year's students to a BA program at an art school. My intention is to explore how we established artists who are involved in education as professors, teachers (or students) in art education affects who will be released to the exclusive educational path as an art school represents our work in the admissions jury. My ambition is to create an awareness of what it might mean for the reproduction of the artist..

Miljöutredning för Bräcke Diakoni

Environmental activities are regulated by the Environmental Code, which applies in parallel with other laws. This report is an environmental review for Bräcke Diakoni. The report aims to find out how much environmental impact Bräcke Diakoni has.

Identifiering av lakbara potentiellt farliga ämnen i gummiasfalt

The main purpose of the project was to identify potential environmentally harmful substances which can be leached from rubber asphalt. A method for analysing asphalt was developed and three rubber asphalt materials were analysed after being cryogrinded. One of the materials was also tested in a road machine made for testing of asphalt paving. The particles created in the machine were analysed in the same manner as the cryogrinded asphalt materials.The asphalt materials were leached by water during 24 hours. The leachates were extracted with dichloromethane, dried with sodium sulphate and concentrated to a small volume.

Fordrande ord : en kritisk diskursanalys av konsertinstitutioners informativa texter inför konserter

The aim of this master?s thesis is to explore concert institutions? informative texts prior to upcoming concerts ? texts in promotional materials and descriptive texts in programme papers. The thesis is carried out from a critical discourse analytical perspective. The discourse analysis is focusing on finding the texts? messages and it asks the question: To whom are these texts addressed? Theoretical support is mainly taken from Foucault?s theory about the relation between power and knowledge.

5 minuter till Luleå : en visuell studie av en stadsinfart

SUMMARYThe demands on the public environment are big and in particular on the environment of communication which we spend a lot of time in on our way to work, school etc. The city-approach is a road section that leads from the periphery of the city to the centre of the city, often through boring and meaningless industrial areas that displays the back side of the city to the voyager on the city-approach. The intentions of this thesis in landscape architecture has been to study one of the two city-approaches to the city of Luleå, the close surroundings and contextual position in the city and not at least give suggestions of ways how the city-approach can be changed, clarified and improved. The study of the city-approach has been made by studying literature that concern city-approaches and the architecture of roads in general. Studies of different analysis methods has been made to find appropriate approaches to work with the specific study of the city-approach to Luleå.
