Bioenergi från röjningsgallringar : en jämförande studie av fyra flödeskedjor från avlägg till förbrukare

When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.

Att skapa ökad hälsa och välfärd : Rehabrådgivarnas påverkan på individens hälsa och livskvalitet i ett governmentalityperspektiv

From a view of health strategies and techniques this thesis wants to throw a light on how the individual in its"health thinking"is governed. A thinking that, according to the author, can lead to a new way of governing as in municipal activity, an activity whose focus is on health and ill-health. The study is done whit a theoretical approach of power, with qualitative interviews as method and analysed from a perspective of Governmentality. The object for the study is Socsam and Rehabrådgivarna in Finspång. Socsam is a local project, and their main task is to create cooperation between health- and medical services, social services and social insurance.

Översvämningsmodellering av ett dagvattensystem

Storm water management has become a more important matter as urban areas are expanding and natural areas are being exploited. As nature landscapes are being converted into hard surface areas storm water flow is affected both in terms of velocity and size. A flow increase can easily result in a flooding if the dimensions of the pipeline system are inadequate. Considering predicted upcoming climate changes, flooding?s may become more common in urban areas in the future.

Analys av massapumps- och mixerarbete vid Metsä Board Sverige AB, Husums Fabriker : Energibesparingsåtgärder vid blekeri 4 & 5 med jämförelse mot ny utrustning

Husums plant has a selection of different pulp pumps at bleaching plant 4 and 5. The displacement- (HC-pump, Sund Defibrator PTD-60) and centrifugalpumps (MC-pump, MCA 42-200, MCP 30/20) are of interest in this report. The centrifugal pumps are controlled by throttle valves, which result in an energy loss. Chemical mixers are used to mix ClO2 into the pulp before proceeding into a holding tower where the bleaching process occurs.The energy demand of the different positions has been measured or calculated to be used in comparisons against new equipment. Quotations were requested and delivered from Valmet and Sulzer.

Systemidentifiering och reglering av en luftningsbassäng på ett reningsverk

A wastewater treatment plant has the task to refine the wastewater from substances that should not be released into the environment. The decomposition process can, in a simple way, be described as follows: micro-organisms breathe oxygen and eat unwanted substances. The environment in which the micro-organism lives is known as sludge and the correct amount of oxygen available in the sludge is important for the decomposition to be effective. The oxygenation of the sludge alone stands for about 30% of the plant?s energy consumption.

Metodik för optisk mätning av sprickbildning i dragen betong på mesonivå

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

Att jobba på callcenter : en kvalitativ studie om det upplevda psykosociala arbetsförhållandet ur operatörens perspektiv

Tidigare studier på psykosociala arbetsförhållanden på callcenter i Sverige har visat att det förekommer både fysisk och psykisk ohälsa bland de anställda. Emellertid har föregående studier varit kvantitativa undersökningar där enkäter och likartade metoder brukats som datainsamlingsmetod. Denna studie har som syfte att urskilja nyanser i och komma nära subjektets individuella upplevelse kring dennes psykosociala arbetsförhållande genom en kvalitativ datainsamlingsmetod. Fem semistrukturerade intervjuer genomfördes med både manliga och kvinnliga operatörer och anställda vid skilda callcenterföretag. Operatörerna beskriver i intervjuerna sitt upplevda psykosociala arbetsförhållande och vad de upplever psykiskt påfrestande i sin roll som callcenteroperatör.

Design och utveckling av monteringsverktyg

With this essay we want to describe the transformation process that the real estate owner has to go through to sell the current rented flats to tenant. We also want to provide an understanding how the valuation is performed in the transformation process and highlight the issues that affects the price in the valuations. In the essay we would like to see if the valuation and the transformation process differ in a public real estate company compared to a private real estate company. Based on this we have asked us the following question to answer: -Is there any differences in how real estate?s are valued in the transformation process between public real estate companies and private real estate companies? We have used a qualitative approach to keep our main question.

Varför En Reformerad Gymnasieskola 2011? : En reformanalys utifrån rektorer och lärares uppfattningar ? kopplat till John Deweys teorier.

This empirical work and base has been to analyze the government?s investigation (SOU 2008:27): the future road ? a reformed high school, which led to the high school reform that the Swedish government introduced as proposition (2008/09:199) about: Higher demand and quality within the high school. Skolverket (part of the Swedish government) has worked with the development of this steering document within their own mission Gy2011 in connection with the high schools during the transition. The reform comes into effect 1 of July 2011. This led to the main purpose to ask questions what high school principals and teachers think of the reform and to what extent it effects the high school programs, the examination system, what impact they see on the individual and the demand from society, and to some extent what the respondent´s answers about the government?s definition of what the higher demand and quality in the reform signify.

Källsorterade systems påverkan på avloppsreningsverk : växthusgaser, energi- och resursanvändning i modellstudie

The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.

Kostnadsallokering genom ABC-kalkylering – en empirisk studie av OMX

As IT service departments in organisations are becoming more complex and customised, the indirect costs are increasing in relation to the total costs. The difficulty of fully estimating and identifying the spread of the cost in the IT service department is increasing. As a result, firms tend to budget the business unit as a total cost rather than as a spread of defined costs. In order to deal with this challenge an ABC calculation will be applied. The Time Driven ABC model will be conducted in OMX´s Servicedesk unit within the IT services.

Genrebaserad undervisning : att stötta flerspråkiga elever i deras språkutveckling

The purpose of this study was to examine how the genrebased instruction applied in multicultural classrooms. My observations were carried out in three different classrooms, whit the educators constantly working on language development off the students. Two observations were carried out in Swedish, with a teacher of Swedish as a second language and the Swedish-teacher working with students together. In these two lessons in Swedish, I took away from Pauline Gibbons model, while the third lesson in civics I assumed from Eija Kuyumcu genre model. Both models are based on the Australian research around the genrebased teaching.
