Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi

The incineration of waste is steadily increasing in Sweden and so is the production of ashes. The bottom ash has for many years been used as construction material in landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it can replace natural gravel in parts of roads and surface constructions. Today this use is only approved within landfill areas where leachate is collected and checked.

Skydd mot nitrat och bekämpningsmedel i dricksvatten : åtgärder och styrmedel i fem länder

In many European countries there is an increasing concern about the occasionally high concentrations of nitrate and pesticides in drinking water. The advent of the EU Water Framework Directive particularly highlights this. The directive states that all large drinking water sources should be identified and protected from pollution before 2009 and that by 2015 all water bodies should reach a 'good status'. In Sweden about 60 percent of the drinking water sources have protection areas. This means that about 700 new water protection areas need to be designated before 2009. This will affect many farmers, restricting their farming practices. The purpose of this study was to investigate which methods are used in other countries concerning nitrate and pesticide pollution from agriculture. From this, the expectation was to generate ideas on what could be undertaken in Sweden when designating new protection areas.

Hur ofta bör småhus sotas? : En samhällsekonomisk analys av ändrade sotningsfrister

Sweden recently changed the national regulation of chimney sweeping. This study has two purposes. The first purpose is to evaluate the effect of this reform to see if the new regulation has led to an effect in terms of increased chimney fires in single-family houses and for the wood-burning and oil-burning stoves, respectively. The second purpose is an updating of a previous study (Mattsson 1994) of analysis of society´s benefits and costs of different alternative sweeping frequencies for wood-burning and oil-burning stoves. This study also has a secondary purpose to examine the extent to which the local sweeping rules vary with climate conditions.  Mattsson, based on his results, proposed that the sweeping requirements for oil-burning stoves should be reduced from twice a year to once every second year and for wood-burning stoves the sweeping should be reduced from four times to once each year.

Effektivisering av den administrativa delen av orderprocessen : En fallstudie på Sandvik Wire

Sandvik Wire needed a review of the administrative part of the order fulfillment process and especially the work around packing and the inventory of finished goods. Therefore we acquired the assignment to investigate the administrative part of the order fulfillment process in the company with the purpose to identify potential for improvement. This investigation was performed with focus on the terminal and packing functions. The purpose with the investigation was also to identify critical factors for an efficient order fulfillment process and investigate if information quality is such a factor.Data was collected through interviews and observations on Sandvik Wire. With the help of this data the information and material flows was mapped, the work within terminal and packing, and adjacent functions was investigated.

Barnets bästa och lämpligt föräldraskap : En studie om hur barnets bästa kan konstrueras i förhållande till lämpligt föräldraskap i medgivandeutredningar vid internationell adoption

The aim of this study was to describe how the best interest of the child can be constructed in investigations concerning permission for international adopt, where adequate parenthood is investigated. Qualitative research interviews were used as method. Seven investigators from six different sections of the city of Stockholm were interviewed. The information was analysed on the basis of a sociological approach to law and social constructionism.The result showed that adequate parenthood is a condition in the interest of the child. Adequate parenthood is specified as the parent?s qualities and possibility to care for an adopted child.

Kaffesump som substrat i biogasanläggningar eller som bränsle i fjärrvärmeverk : en studie av effekter på växthusgasutsläpp och kostnader

Each year, the coffee machines at Ericsson in Kista produce around 100 tons of ground coffee waste.The companies Coor Service Management, Löfbergs Lila and Selecta are all responsible for differentstages in the logistical chain in delivering coffee and, together with Ericsson, they want to increasetheir environmental benefit. The plan is to produce biogas through anaerobic digestion instead ofincinerating the coffee waste in a heating plant. The results are to be presented as different businesscases in which different biogas plants are compared with the reference case (heating plant),comparing costs and environmental impacts.There are two major environmental benefits from producing biogas; reduced carbon dioxideemissions from when fossile fule is replaced by carbon neutral biogas, and reduced emissions fromreturning digestate from the bio reactor to farmland instead of using industrial fertelizer.In order to determine the biogas potential in coffee waste, a couple of properties had to bedetermined in a laboratory. Properties such as the dry substance content, heating value, moisturecontent and ash content. The results show that 100 tons coffee waste could produce around 16 500Nm3 biogas which would contain 163 MWh.The biogas reactor and upgrade plant both need energy gas to function and uses around 14 MWh ofthe produced gas.

Regressionsmodellering av dynamiska råemissioner från statiska mätningar

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

Framtidsoptimerad livscykeloch hantering av versioner : för Scanias Fleet Managementavdelning

In the haulage business customers are constantly requesting new features. Hence thedevelopment department must constantly update their system which ultimatelyresults in a variety of versions of the system. The large number of versions creates acomplexity which often reduces product quality and extends the developmentlifecycle time.The work on the following thesis has taken place at Scania?s Fleet Managementdepartment, which develops tools for hauliers to track their vehicle fleet in real time.The purpose of this thesis was to examine how Scania can handle an increasedamount of versions of the Fleet Management System which Scania expect will be seenin the future. The investigation was conducted by preparing a number of differentscenarios that formed the basis for a discussion of what these different scenarioswould mean for different parts of Scania?s business.

Någon måste göra något! Institutionsplacering: en konkret och för-givet-tagen åtgärd för att hantera ungdomar med beteendeproblem

The purpose of this study was to increase the understanding of the phenomenon that there are so many young people placed in institutions in Sweden despite the valuable knowledge regarding the problems and risks of doing so. The questions that follow in the essay were what guided the social workers to choose institutional placement for youngsters. It went on to also ask if this knowledge could contribute to an increased understanding of why there were so many young people placed in institutions despite the criticism from scientists. To accomplish the goal of the essay, former science in the subject was reported and six social workers within social services were interviewed. The material of the interviews was analyzed with help from the theory of human service organizations, street-level bureaucrats work situation and the new institutionalism.The result of the investigation showed that the social workers choices to place young people in institutions is guided by specific work and organizational factors connected with a belief in the helping function of the surroundings.

Hur används EP&L som strategi- risk- och transparensverktyg?2.

Organizing for value creation : a corporate perspective on urban farming

In the year 1800, about 5 % of the world population lived in cities (World Wide Fund for Nature, 2012, 3). Today that number is about 70 % in Europe and North America, and in 2050 it is expected to be 86 % in the developed world and 67 % in the developing world (www, UN, 2009). In addition, the global population is expected to increase with 2.2 billion people until 2050. As a result of the population increase more food has to be produced which requires more transport from the countryside to the cities. However, this flow of resources faces some difficulties.

Detaljhandelns stora utmaning : en studie om detaljhandelns försäljningskoncept och detaljhandelns kunder

The society has strongly developed and changed the condition of the trades. The retail trade is no exception; it has changed and developed in the same pace as society. The retail trade is a very broad and extensive trade as all people come in contact with frequently. In the past people shopped locally but nowadays people have the entire world as their marketplace because of the development of Internet. Globalisation gives customers wider opportunities, which demands new and different sales concepts.

Repulsion : Subjektivitet och frågor kring det sociala

The scope of this investigation is the conditions under which readings of Repulsion (1965), and its depicted mental illness, took place in Sweden during the censorship debates in 1965, and also how the reception was related to narration and subjectivity in the film. The reason for this is the strong reactions to the images of the main character?s inner state, and concerns about negative effects in the public, that were raised. One major concern is how the film articulates discourses through which meanings are produced; that is, how it works as social technology. My thesis is therefore structured around two levels; textual analysis and discourse analysis.
