The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.

Summary Title: How to make decisions on software based servicedevelopment in the mobile handset industry.?The Rapid Model for Holistic Application Evaluation Authors: Per-Inge AnderssonPatrik Dreveborn Tutors: Björn Regnell, Department of Computer Science,Lund UniversityRobert Wenglén, School of Economics and Management,Lund University Problem formulation: Academically the questions of finding out what constitutes a sound decision base and finding out how to handle the issue of a holistic approach must be addressed in order to make a well balanced and relevant decision model. The core question is which decision criteria to include and which drivers are important in estimating the status of the criteria? Practically to provide Sony Ericsson with a formalized evaluation process for decisions on software development that is transparent, objective and challengeable. Purpose: Academically to contribute to the field of decision making research by elaborating on how to make a holistic, rapid and rational decision model.

Disinfection methods for drinking-water produced at the two water works of Stockholm Water Co are compared in this study. Three different nethods are compared; disinfection with chlorine gas, disinfection with sodium hypochlorite and disinfection with UV-light and monochloramine. The method used is Life cycle assessment, LCA. LCA is defined as the compilation and evaluation of the inputs, outputs and potential environmental impact of a product system shroughout its life cycle. The environmental burden is compared for the three different disinfection methods.

A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.

The purpose with this thesis is to get a compilation of all the critical bolted joints of all enginesproduced at LV Motors. ABB LV Motors produces induction engines with seven shaft heights. Eachengine size exists several variants of components ex. standard shield and flange shield. Depending onwhich components the engine is equipped with arises various types of strains in the engine's parts,certain assembly ways are more favourable than other.The most critical parts in the engine from a mechanical point of view are the screw units betweenshield/stator, feet/stator and bearing cover/shield.

Research suggests that society's vulnerability to natural disasters along coasts could increase as a result of climate change, which is likely to lead to elevated sea levels and possibly an increase in the occurance of meteorological phenomena such as storms and tropical cyclones. Following the Indian Ocean tsunami disaster in 2004 and Hurricane Katrina in 2005, both of which received considerable media attention, empirical data has indicated that coastal vegetation might be able to protect and reduce damages to coastal communities during tsunami events and tropical cyclones.The aim of the essay has been to study the function of coastal ecosystems as protection against tsunami waves and storms from a risk management perspective, meaning that I have, through an overview of scientific articles, compiled current research on how coastal ecosystems can attenuate storm surges and tsunami waves, and analysed how this knowledge can be put into practice in coastal communities from a risk management perspective, i.e. if coastal ecosystems are a viable risk reduction measure, are practically applicable, and if so, how they could be applied.There is empirical evidence suggesting that coastal ecosystems, particularly mangroves, can reduce the strength of a tsunami wave, but full scientific consensus on this issue has not yet been reached. With regard to protection against storm surges, there is extensive scientific evidence that coastal vegetation can mitigate damages and reduce the height of a storm surge, although the wave has to traverse several kilometres inland through thick vegetation for the protection to be effective. A synthesis in the form of a figure regarding the many physical factors that influence wave development through coastal ecosystems has been created in an attempt to simplify and explain the phenomenon.The conservation and restoration of coastal ecosystems can be justified from a risk management perspective, but planting new forest belts for the purpose of disaster mitigation is quite unrealistic and can rarely be sustainable, since, for protection to be effective, the forest belt must extend several kilometres inland from the coast, and would thus likely prove difficult to implement along coastal societies..

The main purpose of this thesis has been to find a way to evaluate the soil parameters for the Total sounding method (TS), such as the inner friction angles and settlement modules. This study only includes an analysis of soil profiles from the Stockholm region. The chosen location for the study is a proposed residential area east of Igelstaviken in Södertälje. Presently, the subject plot is located in a residential area and is also adjacent to a school area.Total sounding is originally a Norwegian soil testing method. The differences between the sounding methods (weight-, ram-, CPT-sounding) are for instance how the sound is driven into the ground and what kind of parameters that are registered.

Vi, Anna Nilsson och Jeanette Svensson, valde att producera musikvideos under vårat kandidatarbete på Blekinge tekniska högskola. Detta eftersom vi båda har ett stort intresse till musik och rörlig bild. Vi valde att göra två stycken för att lära oss produktionens process grundligt och för att nu kunna jämför de båda och av detta ta lärdom. Den ena musikvideon gjorde vi till en skånsk duett som heter KC och den andra till Advance Patrol. Båda låtarna är inom genren hiphop. Vårt mål med projektet var att skapa två videos som inte följde den generella mallen för hiphop-videos.

An uncountable number of companies are present in foreign markets as a result of what we commonly choose to call globalization. This is especially true for Swedish companies traditionally operating on small markets. A company that is about to establish on a new market is faced not only with possibilities but also with challenges and risks. Researchers have found that companies that establish on foreign markets will have to deal with competitors on the national as well as on the global market, and therefore need consider how they globalize their brands. In addition to this, a brand can only reach international success if its message is coherent within and across every single market.

Bakgrund och problem: Majoriteten av försäljningen mellan företag, samt mellan företag och offentlig sektor sker via handelskrediter. Detta leder till att företagen ofta blir utsatta för risker i form av sena och uteblivna betalningar. I sådana situationer finns det behov av riskreduceringsmekanismer som ska reducera och minimera dessa risker. Mekanismerna för reducering av risker har vi fördelat i två kategorier, privata och offentliga. Avsikten med uppsatsen är att undersöka vilka av dessa mekanismer som har störst inverkan på beviljandet av handelskrediter.

Västerländsk mindfulnessmeditation har sina rötter i tusenårig buddhistisk tradition, främst genom vipassana- och zentraditionerna. Senaste tiden har mindfulness ökat i popularitet och blivit en accepterad klinisk metod i former som mindfulness based stress reduction. Möjligheten att undersöka dess effekter genom neurovetenskapliga metoder bidrar med intressant och viktig forskning om mänskligt välbefinnande. Dock har tidigare studier visat på bristande samstämmighet vad gäller resultat och metod. Uppsatsen är en litteraturstudie där det huvudsakliga syftet är att utifrån nyare studier undersöka de tydligaste effekterna på hjärnfunktion och struktur av långvarigt praktiserande av mindfulness utifrån vipassana- och zenmeditation.

This is a critical discourse analysis of the conformation of the conflict in Goma, Democratic Republic of the Congo, as constructed by Ekot, a news-show on Radio Sweden. The ambition of this bachelor thesis is to examine the production of a Congolese conflict for a Swedish audience and to find out how the construction differences with and without a reporter in the field. To obtain this purpose the narrative is studied as well as the use of voices that define the conflict. The construction of proximity between Swedish audience and the Congolese event and the meaning of sound to stabilize the formation of discourse within foreign news is examined as well. To conform and explain foreign news it must be put in relation to a starting point.

This report analyzes and examines a hypothesis for finding a method to optimize thelength of the delubrication process time based on a total charge weight. The work hasfocused on the holding time for delubrication and the total charge weight.An important step in the manufacturing chain of cutting tools is when the greenbodies undergo the sintering process. Today, the delubrication step has the sameprocess time independent of the total charge weight. An implementation of a methodto adjust the delubrication process time would give more consistent quality of thecutting tool´s internal characteristics but also reduce the time course of the sinteringprocess. In the present project two methods for this goal were tested, thedevelopment of an algorithm and a weight interval subdivision with associateddelubrication process times.During delubrication a pressure increase is observed due to the decomposition of thePEG in the powder mixture.

Buildings worldwide account for 40 % of the total energy use. Climate change is of increasing importance, but few are willing to reduce their standard of living or get a higher cost for the change. Energy efficiency of existing buildings gives the greatest benefit economically and environmentally. The real estate company Klövern AB manages 46 properties in Karlstad. Heating is the major cost of the total operating costs of real estate. Rising energy prices increase the need for Klövern AB to improve energy efficiency and to investigate alternative sources of heat.

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.
