Karaktärisering, utvärdering och avsättning av Stena Metalls magnetiska fines

With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE? requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled.This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden.

En empirisk studie av Value-at-Risk-prediktering med hjälp av GARCH-modeller

This paper describes a study examining four different GARCH models AR(1)-GARCH(1,1), AR(1)-EGARCH(1,1), AR(1)-APGARCH(1,1) and AR(1)-GJR-GARCH(1,1), and their ability to predict future volatility and thereby providing more reliable estimates for Value-at-Risk. The study is based on daily observations for the return of the OMX Stockholm 30 Index, during the time period 31st December 1996 to 29th December 2006. The coefficients for these GARCH models have been estimated using a five-year rolling estimation window, with one-year lags, for five different in-sample-periods. These five in-sample-periods, and the coefficients given by them, have been used to generate five out-of-sample predictions for the volatility in each year. Using these volatility predictions, the daily Value-at-Risk has been calculated for confidence intervals of 90 percent, 95 percent, and 99 percent, respectively, during the time period between 1st January 2001 and 29th December 2006.

Utredning av solenergi för drivning av sorptiv kylprocess för inomhusluften på Stockholmsarenan

Cooling down the indoor air can be done in several ways. One way is desiccantcooling which will be used at the Stockholm Arena. This method is used in airhandling units that use temperature changes and moisture fluctuations in the air. Oneof the steps is to add heat during the cooling process in order to reduce the relativehumidity of the exhaust air. The air passes thru an adsorptions rotor which thenabsorbs moisture from the supply air.

Hur personer med psykisk ohälsa upplever bemötandet inom primärvården : En litteraturöversikt

Background:Mental illness has increased in Sweden and the individuals seeking care expect to be met with respect. The way patients perceive themselves to be treated by health care professionals plays a central part to care and treatment of patients, and the patients experience will decide how future care will proceed. The majority of complaints from patients with mental illness suggest that the way they are treated in health care is inadequate. For people with mental illness it is crucial how they perceive themselves to be treated since poor treatment can lead to reluctance in seeking future help. Aim: The purpose of this study was to describe how people with mental illness perceive themselves to be treated in primary health care.

SMED implementation vid slipoperation

The thesis has investigated how Sandvik Coromant could implement the SMED principle on one of their grinders groups and what improvements it would lead to. The aim of the thesis is to identify the current situation and investigate how their setup times would be affected by SMED. The work initiated with a literature analysis about the SMED principles and then proceeded with an analysis of the current situation where the activity was time mapped. The analysis consisted of time trials of the process that the thesis would include. The time studies revealed opportunities for structural improvements to create environment for a more structured process.

Tungmetaller i lakvatten : avskiljning med mineraliska filtermaterial

Four different kinds of filter-materials with reactive surfaces have been studied concerning their capacity to absorb heavy metals in leachate from a municipal waste deposit. The heavy metals studied were: lead, cadmium, copper, mercury, chromium, nickel and zinc. The leachate contains high levels of dissolved organic carbon (DOC) and has a high pH-value along with a high buffer capacity. These characteristics of the leachate make it difficult to remove pollutants and require efficient filters. The filters that were examined in the report are blast-furnace slag with CaO, sand covered with iron oxides, olivine and nepheline.

Värdet av vinglaset : En studie om hur vinglasets sensoriska och estetiska egenskaper påverkar gästens vinupplevelse

The aim of this study is to examine how preschools contribute to the forming of identity in children, with a specific focus on the quiet and socially withdrawn child. How do the teachers describe the quiet child and the socially withdrawn child? Are there any opportunities for children to be quiet/withdrawn in preschools? These questions have also been analysed from a gender perspective. The method chosen is qualitative method. Nine preschool teachers from two Swedish preschools have been interviewed.

Hinder för svenskt trä inom den italienskabyggbranschen i allmänhet och produktsegmentenfönster och dörrar i synnerhet :

Italy is the third largest market in Europe with a population of almost 58 million. The country is the tenth most important market for Swedish sales. Italy has a fairly good economy at the moment and the forecast tells of an increasing strength during coming years. Despite all of this, Sweden is exporting a fairly small amount of wood to Italy. Only around 2,3 % of all Sweden?s wood export goes to Italy.

Purpose: The main purpose of our study is to explain how the disability management in the municipality of Karlskrona can design its balanced scorecard from a theoretical basis. The mission of the balanced scorecard is to improve the management control system. To achieve the main purpose we have to study the problems that exist with the current control system, which then becomes our second purpose.Method: Our study has a qualitative approach. The design of the study is a case study in which one case has been looked at. The empirical data is collected through interviews and documents. We have gathered our theory through scientific articles and literature.Results: The goals set by the board are unclear and hard to define.

Är det möjligt att använda SCR-rening av rökgaserna vid inblandning av avfall i biobränslet?

Waste appears to be a low-cost fuel compared to biofuel. This Masters thesis was conducted for Vattenfall Utveckling AB and deals with how waste in the fuel affects the performance of a SCR-catalyst. Different mechanisms of deactivation were surveyed, focusing on the poisoning mechanism. A literature study was carried out, which was used as a reference when analysing the results.Small samples (9x2x2 cm, 64 pieces) cut out from a full-scale unused honeycomb catalyst were exposed up to 1500h in two different combustion plants, Johannes in Gävle (co-combustion) and Högdalen in Stockholm (waste-combustion). The activity was measured mainly at 300°C but also at 250, 350, 375 and 400°C.

Omslagsbilder till DVD-filmer : Exempel på visuell kommunikation

This thesis is about cover illustrations of DVD movies as examples of visual communication. I have studied the cover illustrations of the three movies Gran Torino, Secret Window and As White As Snow. My research assignment has been to find out how the cover illustrations of DVD movies communicate in relation to the story. I have also been looking for what makes a cover illustration interesting and if the interest in itself is individually considered or if there are certain general rules regardless of the observer.To reach a conclusion I have been studying components in advertising pictures, visual communication and how the commercial producers use advertising to communicate with the observer. Semiotics, advertising and comparisons between the cover illustrations have been my method for analyze.I have come to the conclusion that cover illustrations are meticulously produced, and that every single part of them is important for the observers? over all impression and interpretation of the cover illustration.

Uppfödning av okastrerade hangrisar - ett alternativ till obedövad kirurgisk kastrering av smågris

Pigs kept for meatproduction are often surgically castrated to prevent aggression and boartainted meat. Castration without analgesia and anesthesia is painful and causes a lot of stress to the pig. There are alternatives such as to surgically castrate the male pigs with analgesia and/or with anesthesia, immunocastrate or keep them as intact males. In Sweden the most common practice is to surgically castrate the pigs before they are seven days old. The impact on the pig is that the incision causes pain and stress, which may lead to changes in behaviour, reduced appetite, reduced growth and a higher risk of infections.

Smakdomarna och Fredrika Runeberg explicit subjektivitet och värdering i svensk litteraturhistorieskrivning

This essay is a study of explicit subjectivity and valuation in Swedish literary historiography from a power perspective. The methodology involves qualitative perusal of literary handbooks from 1915 to 1999. The author Fredrika Runeberg is taken as a window, in that I have examined if and how she is described in the selected handbooks. The main purpose has been to see if subjectivity in disparaging terms and condemnation of authorship have become more evident during the years under consideration. I have related the twelve selected handbooks to Hallberg's five methods for literary historiography.

Den rätta balansen : En kvantitativ studie om sambandet mellan faktisk, önskad arbetstid och hälsa

The purpose of this study is to examine whether there is any connection between working hours, desired working hours and the worker ?s health. The study also aims to investigate if there are any differences over time. Earlier studies have shown that individuals need a balance in their life between worked hours and free time. This balance seems to be important for employees if they want to lead and remain a healthy lifestyle.

Analys och organisering av ö-drift för en samförbränningsstation vid Åmotsfors bruk

Åmotfors Bruk AB (ÅBAB) has today an inefficient production of steam for the manufacturing of paper. Unpredictable energy prices and modernisation of the current equipment has been the underlying factors to invest in a thermal power plant, mainly driven by garbage. This facility will not only use the steam for paper production, it will also generate electricity through a steam turbine. Today, when a fault on the supplying line occurs which leads to disconnection of the external grid, all the support of electricity to Åmotfors Bruk (ÅB) will disappear. This will lead to major interruptions in the paper production, which will cause severe economical losses.
