Analys av energiförbrukning, Akzo Nobel Functional Chemicals AB

The main purpose of this project was to make a survey of the steam and electricity consumption at Akzo Nobel Functional Chemistry AB and give suggestions of how to minimize them. These three different areas were focused on. First to make a survey of all the most important consumers, second to find the electricity consumption of the air compressors and the amount of waste heat produced from them. The third area was to calculate a model of how much fresh water that is used during a cooling sequence in the water based heating/cooling system of the reactors and give a suggestion of a suitable reuse for this water.The main result is a total survey of the energy consumption in steam and electricity. The survey shows that the second largest group after drying is heating of ventilation which gives big potentials of reducing the total steam consumption if there is a way of being self supporting in ventilation heat.

Stem injection of different nitrogen forms into young Norway spruce

This master thesis has been a pilot study preceding a forthcoming project of a larger scale with the long term objective to separate the direct effect of added nitrogen on soil processes from indirect effects via trees. The aim of this study has been to investigate the allocation of nitrogen following direct injection of liquid solutions into the xylem of 40 year old Norway spruce. The field site is located at Flakaliden (64°07?N, 19°27?E), approximately 60 km northwest of Umeå, Sweden. A total of 18 trees were selected for treatment, equally divided between three treatments, potassium nitrate, glutamine and water (control).

Effektiv ledning av idrottsevenemang : en studie i ledarskapskommunikation vid idrottsevenemang

AimThe purpose was to make researches into and illustrate how the leadership looks like at sporting event, concerning human communication.The following issues have been treated: What is characteristic for leadership during a sporting event? What does communication look like within the managerial? What kind of problems appears or can appear on account of defective communication at sporting event.MethodThe method being used is qualitative, based on interviews with three group leaders and one project leaders, all working for a summertime sporting event. As a form of basis a search for existing literature and articles on this subject were accomplished. The selection was made after having consulted a person of proportionately high station, active at the invested sporting event.ResultsAs a result of the essay, I have brought out, that leadership is different from group leaders and project leaders. Their difference in assignment demands different leadership, and that explains the occasion.

Hur ofta skrivs anvädningsområde t på läkemedel inom ATC-rupp N04 (medel vid parkinsonism)?

Adherence to medical ordination is low and for long-time medication it is estimated to be as low as 50 percent. Depending on the prescribed drug this could lead to adverse effects and/or loss of effect of the drug. Information about why a drug is prescribed is important patient information and is thought to help increase compliance with the physician?s prescription. According to results from a recent study of visits to the emergency room at Karolinska Universitetssjukhuset in Solna, Stockholm, medically related problems were the cause in about 30 percent of the cases.

Hur påverkar naturvårdsåtgärder mängden av vedlevande insekter : Manuellt dödade träd vs självdöda

Today?s forest managers implement a large number of methods to increase the amount of dead wood in Swedish forests. They use everything from high cutting of trees to girdling trees and burning forests. However, implementation of these measures without proper knowledge of their consequences is a common problem. This study has been performed to increase knowledge about two of these measures, girdling and high cutting, and how these actions affect the number of wood-living insects living on dead trees.

Svartgran ? ett alternativ när allt ser mörkt ut? : en kartmodell för att visa lämpliga ståndorter för odling av svartgran

A common problem in forestry is plant death caused by frost. The risk of frost is highest on wind protected, flat or low-lying areas in the terrain. Here you often have regeneration problems with Norwegian spruce which is especially sensitive to spring frost. Swedish tree experiments have shown that the black spruce can be a suitable alternative on these areas, for example on moisture frost prone areas. The species originates from North America and its pioneer tree characteristics make it more frost hardy than Norwegian spruce.

Staden mellan visionerna och asfalten: En studie av politiska idéer och visioner om staden ur ett rumsligt perspektiv

Urban planning is not only a matter of architectural trends; it is first and foremost political. This thesis seeks to understand the links between political ideas and visions for the city and the physical structure of the city. The study aims to construct a model to help understand these links, a helpful tool in analysing a city, focusing on the one hand at the physical structure of what I call "The City as a Welfare Provider" and on the other hand at "The City as a Growth Engine". It also sets out to test this model in an empirical study of Stockholm and the soon-to-be built district of Norra Station in the same city.The analysis shows that Stockholm has ambitions to be a welfare provider to its citizens, but have also adopted to a discourse of interurban competition which stresses the importance for the city to enhance economical growth. What is interesting is that the physical structures promoted in the planning documents of Stockholm are nearly exclusively those associated with the model of "The City as a Growth Engine"..

Solenergi på Kvarnholmen

In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.

Optimering av ett småskaligtvattenkraftsystem

This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.

Den bäcknära zonen vid små skogliga vattendrag i Värmland : generell beskrivning, förekomst av traktorspår samt kvicksilverhalter i körpåverkat ytvatten

Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

Validitet av observationsbaserade mätningar av armarbetsställningar hos pappersbruksarbetare

Abstract    Objective: The aim of the present study was to investigate if inclinometer estimates of arm posture during paper mill work differed between periods of different arm visibility. The aim was also to identify strategies for and difficulties in assessing body-visibility on video. Methods: The study consisted of two parts, where part 1 aimed to investigate the validity of observation-based assessment of arm posture during paper mill work. Study 2 was a survey among people with experience in assessing the posture of paper mill workers from video. Results: The total time for the right upper arm visibility indicates that it was on average visible in 54%, partly visible 15 %  and not visible 31%.
