This thesis has been carried out in autumn 2009 at Uppsala University for Boliden Mineral AB. Physical modelling has been used to model a comminution circuit. The model has then been linked to a PLC.When a concentrator is about to become operational Boliden Mineral AB have been looking for a way to test the PLC. The purpose of this report has therefore been to develop models for the subprocess in a concentrator and link these models to the PLC. The subprocess was a comminution circuit in Aitik36.

Background: The strategic importance of purchasing departments is increasing, yet supply risks are rather uncharted. The procurement of coffee involves supply risks and the purchaser needs to be able to handle these to enable the roasting-house to produce coffee as specified. Purpose: To chart risks in connection with the procurement of coffee as well as the possibilities of handling these. The thesis also examines if general risk management theories are applicable on the supply risk present within Swedish roasting-houses and can become an integral partof the purchasing process. Method: A qualitative case study of the purchasing process of Swedish roasting- houses.

The authors study the effects of brand salience on how consumers form brand attitudes and how consumers value the importance of various brand attributes. The study was conducted through two separate tests, the one focusing on the link between brand salience and brand attitudes and the other focusing on the link between brand salience and evaluations of attribute importance. Both tests measured brand salience as the ease with which brands are recalled by respondents who have been cued with a specific product category. The results show that brand salience has direct effects on both brand attitudes and the evaluation of attribute importance. As brands are recalled, high brand salience for a brand creates a more positive attitude towards that brand in the mind of the consumer.

Hemsidan är den enskilt största kommunikationskanalen mellan Ericsson och potentiellt framtida anställda. Företaget har idag problem med att den globala karriärhemsidan inte uppfattas som användarvänlig av särskilt studenter, och detta examensarbete syftar till att definiera krav för hur en global karriärhemsida bör utformas för att vara användarvänlig och välkomnande för studenter.Med en användarcentrerad designstrategi och en teoretisk bas inom interaktionsdesign och human factor syftar avhandlingen till att förstå vad studenterna efterfrågar och hur Ericsson kan möta och överträffa dessa förväntningar. Tester, workshops, utvärderingar och intervjuer har använts för att iterativt utveckla en prototyp och kravspecifikation.Studien visar att det finns två huvudsakliga typer av användare att designa för: de med ett tydligt mål att hitta ett jobb och de som försöker ta reda på om företaget är av intresse. Vanliga känslor hos användarna att ta hänsyn till ärångest, ensamhet, beslutsamhet, spänning och glädje. Några av slutsatserna kring den befintliga karriärhemsidan är att den vänstra menyn inte är organiserad på ett sätt som hjälper användaren att hitta vad han/hon letar efter, innehållet i mitten är för allmän och tråkig för många användare och högerspalten används sällan, trots att den innehåller vissa användbara funktioner.

Vårt arbete var att skriva en handledning för att studenter och lärare snabbt ska komma igång med programmet Altium Designer 6 och utvecklingskortet som Institutionen för Teknik och Naturvetenskap (ITN) har.Utrustningen som vi använt heter Altium Designer LiveDesign Evaluation Kit. Det är ett paket bestående av ett utvecklingskort som är försett med en FPGA-krets. FPGA (Field Programmable Gated Array) är en krets innehållande logiska komponenter.Denna krets kan man programmera till olika logiska funktioner med språket VHDL. För programmering används programmet Altium Designer 6 I vår handledning finns information om utvecklingskortet, lite om hur det hårdvarubeskrivande språket VHDL är uppbyggt.Rapporten innehåller sedan steg för steg beskrivningar av hur man går till väga för att programmera och provköra enklare VHDL-exempel från programmet Altium Designer 6. Allt för att man snabbt ska få grunderna så man kan skriva egna program..

Agencies towards Sustainable Development ? A Study of Environmental Management Systems in Governmental Agencies 2005A vision of the Swedish government is to build an ecologically sustainable society. A tool in this effort is to implement environmental management systems (EMS). The aim of the thesis is to present in which phase of the implementation of EMS Swedish governmental agencies are. This will be done by compilation and evaluation of agencies? yearly environmental reports.The thesis is written in co-operation with the Swedish Environmental Protection Agency (Swedish EPA).

This paper presents an approach in contemporary, abstract art for a new way of experiencing modernist abstraction. This has not been possible until now, about 40 years after the postmodern turn against modernism in art, and the closely connected formalism. This new approach is represented in this paper by the Swedish contemporary artists Ann Edholm and Jacob Dahlgren. Modernist artists such as Kasimir Malevich and Piet Mondrian receives a new relevance to contemporary abstract art. This opens up for a new, more complex and more dialectical understanding and re-evaluation of modernism and its abstract art.This is shown by a historical and chronological investigation which highlights modernist abstract art, formalism, and the critical and post-modern Neo-geometric ?abstraction? of the eighties.

Detta examensarbete har utförts på uppdrag av Ayen Technology AB i Haparanda som är ett litet företag inom satellitkommunikationssektorn. Syftet bakom projektet var att utveckla en takmonterad, motoriserad antenn för satellitkommunikations vanligen kallad ?Drive-away? eller SNG i branschen. Detta skulle bli en helt ny produkt för Ayen Technology. Man skulle utgå från en existerande reflektor utvecklad till en annan produkt utvecklad av företaget.

Graphic design is an integrated part of the public spaces we move through in our daily lives. This thesis explores the emotional aspects of graphic design, with a focus on environmental graphics for the public space. The goal is to find ways in which the emotional aspects of a design solution can be varied without compromising the practical aspects, i.e. affect the conveyance of information. This goal is pursued through an analysis of historical and contemporary literature as well as by design practise.

A study was made to evaluate how current measurementscould help to determine how particles from fish farms are dispersed. During sixweeks of the summer 2012, two different current measurements were conducted.One of them consisted of measurements each fifth minute at 5 m and 15 m atthree locations for 14-16 days each. The other consisted of profilemeasurements at each location at four times during the period of six weeks. Forthe current measurements two instruments (model RCM 9) were used. A two weekmeasurement can give enough data to make an evaluation of how the currents at alocation will transport litter from a fish farm.

Syftet med den här uppsatsen är att belysa hur individer med funktionsnedsättning skapar sin förmågodeprivation, ?capability deprivation?, i relation till de möjligheter till utveckling som framkallas av strukturella och personliga faktorer. Förmågodeprivation innebär att människan upplever brist på friheter och rättigheter för att använda sina förmågor till att nå sina personliga mål. Dessa mål kan vara av ekonomisk, social och kulturell karaktär och kan betyda en utveckling hos individen som denne värderar högt. När förmågodeprivation uppstår likställs den med fattigdom.

The scope of this master´s thesis is the issue of usability in relation to interface design,in particular the interface of a university library´s online public accessed catalogue, orOPAC. Since the OPAC can be seen as the library´s ?shop window? to the world, it isof great importance that the interface to the OPAC can be used by patrons witheffectiveness, efficiency and satisfaction.The master´s thesis is based on a qualitative study performed at Karolinska InstitutetsUniversity library, and contains both a usability evaluation and an interview study. Twointerfaces were evaluated: a standard web interface provided by the system supplier, andan interface developed in-house by Karolinska Institutet´s systems department. The twointerfaces are both connected to the same online library catalogue, thus making possiblea comparative study..

An inflammatory reaction is induced after release of proinflammatory mediators such asinterleukin 1 and 6 and tumour necrosis factor ?. These mediators stimulate the liver tosuppress the syntheses of albumin and endure the syntheses of acute phase protein forinstance C-reactive protein. The aim of this paper was to perform a method validation on animmune turbidimetric assay to quantify C-reactive protein in canine serum at the laboratory atSkara Animals Hospital, Skara, Sweden. The validation involved evaluation of the assaylinearity, precision, stability and recovery.The method was proved to be linear for both TruLab control and Medinor control.

The aim of this study is to describe how reviews of literature in Bonniers litterära magasin and Expressen changed during the period 1964-2004. The investigation is based on 20 reviews of novels and short stories, which are analysed with a method described in Hellspong and Ledin (1997) and inspired by Halliday. The theoretical frame of the investigation is founded on critical discourse analysis (Fairclough 1992 & 2001) and Habermas´social theory of the public sphere.The investigation shows, among other things, that the reviews became shorter and easier to read in both paper during the period. The investigation also shows that the genre´s style, composition and contents are relatively stable, and that current ideologies in society have a tendency to be reflected in the reviewers´evaluation of the books. To generalize, the reviews thus developed from a poetic genre in 1964, to become political in the 1970s, academic in the 1980s, feminist in the 1990s and finally an intermedial genre in 2004..

Agricultural soils constitute the base in human food production and soil content of organic matter and plant nutrients together with soil microbial activity are all important parameters for high crop yield of good quality. These parameters are dependant on proper fertilization.Anaerobic digestion of organic wastes for biogas production generates a liquid residue called biogas residue (BR). It contains organic material and plant nutrients which makes ita potential fertilizer for arable cropping. However, it also contains heavy metals and toxic organic compounds and it is therefore in need of evaluation before usage.Microbial tests were performed aiming to evaluate the agronomic traits of four different BR and to find a viable procedure for evaluating slurry fertilizers. Two experiments where soil respiration and soil potential denitrification activity (PDA) was measured at fertilizer addition were performed.
