Användning av rötrest från kombinerad etanol och biogasproduktion : en jämförelse mellan tre alternativ

Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

Persona : En metod att utveckla och införa persona i en organisation

AbstractIn this thesis we aim to extend the current theories about a concept called persona. A persona is a model of a user, mostly based on qualitative research and made with such accuracy that it to some extent can be used as a replacement of a real user in a development process and as a communicative tool. We will present a way of constructing this persona without meeting the actual users and follow up with interviews from the organization using them. This will lead to a model over the process of introducing personas as a concept in an organization,previously not familiar with the concept. The model is adapted to also work for projects and organizations where the concept is already known..

Medveten närvaro och beteendeterapi vid behandling av primär insomni : Effekter på sömn, uppmärksamhet, oro och ruminering

Uppmärksamhet/övervakning (monitoring) är en viktig komponent vid utvecklandet och vidmakthållandet av insomni. Genom medveten närvaro (MN) kan förmågan att rikta uppmärksamheten tränas upp. Syftet med studien var att undersöka effekten av MN och beteendeterapi (BT) vid behandling av primär insomni hos personer med hög uppmärksamhet/övervakning av sömnrelaterade stimuli. Behandlingens effekt på sömn och uppmärksamhet samt en eventuell sekundär effekt på oro och ruminering undersöktes. En single-subject design med en konstruktiv strategi användes och två behandlingar gavs, där hälften av deltagarna fick BT och hälften fick BT+MN.

Produktivitet och lönsamhet vid skogsbränsleuttag i klena gallringar : en tidsstudie av Vimek 608 BioCombi i contortabestånd

The annual demands for forest fuels increases in Sweden. At present, large unutilized biomass resources is found in young, dense forests from which about five million oven-dry tonnes (ODt) (23 TWh) could annually be extracted as forest fuel. But harvesting small trees give high logging costs and new cost-efficient harvesting techniques are therefore required. The aim was to study the productivity of Vimek 608 BioCombi in forest fuel thinning of Lodgepole pine and to calculate the economy of the harvesting and estimate the thinning quality. The time study was performed in Åmarken in the county of Västerbotten.

Liquid diesel biofuel production in Sweden : a study of producers using forestry- or agricultural sector feedstock

The transportation sector is the only sector of the Swedish society that is still increasing the emissions of carbon dioxide and other green house gases. Diesel fuel represents one of the fuels that contributes to these emissions and the use of diesel fuels is increasing every year. The main purpose of this study was to make an estimation of the current business situation for producers of liquid diesel biofuels in Sweden such as biodiesel, synthetic diesel and crude tall diesel and examine the forces of competition of the industry today and its future prospects. The study revealed that the rivalry among the existing firms was low mainly due to the geographical spread of the companies. Moreover the success of the biodiesel industry was influenced by a long-term guarantee of the tax exempt for biofuels and by the price level of petroleum diesel.

Är BIM lönsamt vid projektering av ett småhus?

This report brings up the question - ?Is BIM profitable when planning a single-family home??.The methodology for finding the answer to this question is firstly to state the definitions of BIMand the company that is projecting by using the BIM-model. The answer is then obtained byanalyses of the factors of profitability with respect to: time, opportunity of revision, problemvisualization, preference adjustments and energy. A BIM-model has been made simultaneously asthe writing has proceeded to get a perception of how a BIM-model really matters for the analysis.The analysis shows that the answer for the question depends on further factors. The factors thatare mostly discussed are the company?s intentions and the complexity of the house.

Förebyggande förbättringsarbete med Design for Six Sigma

Design for Six Sigma (DFSS) is a further development of the Six Sigma draft to carry through preventing quality measures in developing and designing of new products and processes. With increasing demands on enterprises development processes to be more safety and faster the need of DFSS arise as a product, process and service development concept in the organisations. Design for Six Sigma aims to improve and structure the development process of an organisation and consider the application of the innovation problem solving. The concept aims to leave the structure of the traditional Six Sigma concept and instead, from an innovative perspective, search for new solutions to existing problems. The concept constitute of a toolbox with a lot of quality tools that are divided into phases in a development model.

Viljebegreppet och psykologin : En studie av psykologins framväxt som vetenskap i Sverige genom en analys av viljebegreppets betydelseförändring

The aim of this study is to elucidate the process in which psychology was separated from philosophy and established itself as a distinct academic discipline in Sweden. I argue that the concept of will, as well as the concepts of thinking and emotion, have a lot to tell us about the rise of academic psychology in Sweden. This is done through an analysis of psychology textbooks, encyclopaedia-articles and academic texts on the themes will and psychology, from around 1800 till 1950.Prior to the establishment of the first chair of psychology in Uppsala 1948, the discipline was above all a part of the philosophical discipline. For psychology to become a science of its own, it was crucial to obtain a position among the empirical sciences. It thus had to distance itself from philosophy, and in particular from metaphysics.

Att styra bilanvändning mot en hållbar utveckling. Om geografiska livsvillkor kontra offentliga ingrepps betydelse för bilanvändning.

Car usage is determined by several facts, e.g. living conditions determined by geographical matters. There is a political will to control car usage with different kinds of incentives since car usage generates environmental problems.
