De förändrade ansatserna inom feministisk utvecklingsekonomi för med sig nya sätt att tala om kvinnor, män och utveckling. Genom att analysera texter skrivna inom området feministisk ekonomi från 1960-talet fram till början av 2000-talet dokumenterar den föreliggande studien på vilket sätt språket hos textproducenter inom utvecklingsekonomi konstituerar och är beroende av dessa skribenters inställning till utvecklingsfrågor och till kvinnor och män. Analysen fokuserar på hur aktiverings- och passiveringsprocesser används i representationen av de två huvuddeltagarna, kvinnor och män, hur begreppet genus introduceras och hur utvecklingsfrågor förändras genom ansatser, över tid och mellan genrer. Den teoretiska ramen sträcker sig över olika discipliner: systemisk funktionell grammatik och kritisk diskursanalys, men även organisatorisk diskursanalys och utvecklingsstudier. Texterna som valts för analysen härstammar från tre olika källor: planer från världskvinnokonferenserna organiserade av Förenta Nationerna, resolutioner om kvinnor och utveckling antagna av Förenta Nationernas generalförsamling samt handlingsplaner för kvinnor och utveckling författade av Förenta Nationernas livsmedels- och jordbruksorganisation FAO. Den lingvistiska analysmetoden bygger på det system av roller och sätt att representera deltagare som utvecklats av Halliday och Van Leeuwen. För varje årtionde och varje genre granskar studien förändringarna i processtyper och deltagarroller, samt förändringen av fokus på kvinnorelaterade frågor och konceptualiseringen av genus. Den kvantitativa analysen kompletteras och förstärks av en detaljerad analys av textfragment från olika tidpunkter och ansatser. Studiens resultat är av grammatisk och lexikal natur och de är relaterade till genus, genre och tid. Studien visar att aktiveringsprocesserna är betydligt talrikare än passiveringsprocesserna i representationen av kvinnor. En bättre förståelse av deltagarrepresentation uppnås dock via en omgruppering av de grammatiska processerna i identifierande, aktiverande och riktade processer. Skiftet från fokus på kvinnor till fokus på genus är inte så mycket en förändring av processerna som representerar deltagarna, utan mer en förändring av retoriken i ansatserna och deras fokus: från integration av kvinnor till kvinnors empowerment, från kvinnors situation till genusrelationer, från brådskande tillägg till social konflikt och samarbete.

Populärkulturen har i dagens läge kommit att utgöra en allt mer viktig och central inspirationskälla för allt fler människors konstruktion av den egna religiösa identiteten även inom traditionella och institutionella kristna sammanhang. Denna avhandling belyser denna utveckling i ljuset av den finländska kristna metallmusik-kulturen - en sällsynt stark sammanblanding av protestantisk kristendom och en utpräglad och kontroversiell populärmusikform och dess kultur. Fokus riktas framför allt på hur den kristna metallmusik-kulturen blir meningsfull för sina medlemmar genom de sätt på vilka den konstrueras diskursivt, dvs. genom de sätt på vilka den representeras och talas om bland sina egna anhängare. Den diskursiva konstruktionen av den kristna metallmusik-kulturen utforskas på ett såväl bredare transnationellt som ett finländskt nationellt plan. Studien redogör även för den kristna metalmusikens och -kulturens huvudsakliga verbala, visuella och estetiska kännetecken. Uppbyggnaden och spridningen av dagens transnationella kristna metallmusik-kultur undersöks även i ljuset av det teoretiska konceptet scene. Avhandlingens centrala argument är att den kristna metallmusikscenen erbjuder sina medlemmar en mängd resurser för skapandet av ett alternativt och komplementärt religiöst uttrycksätt, religiös praxis och en alternativ kristen identitet.

This study compares different electric propulsion systems. Results of the analysis of all the advantages and disadvantages of the different propulsion systems are given. This thesis estimates possibilities to apply different diesel-electric propulsion concepts for different vessel types. Small and medium size vessel’s power ranges are studied. The optimal delivery system is chosen. This choice is made on the base of detailed study of the concepts, electrical equipment market and comparison of mass, volume and efficiency parameters. In this thesis three marine generators are designed. They are: salient pole synchronous generator and two permanent magnet synchronous generators. Their electrical, dimensional, cost and efficiency parameters are compared. To understand all the benefits diagrams with these parameters are prepared. Possible benefits and money savings are estimated. As the result the advantages, disadvantages and boundary conditions for the permanent magnet synchronous generator application in marine electric-power systems are found out.

Causticizing plant is an important part of kraft pulp mill. It uses green liquor from recovery boiler as a raw material and consumes lime to produce white liquor, which is an important chemical used in pulping. Lime kiln is a part of the causticizing process. It is used to convert lime mud, a by-product obtained from the causticizing back to lime in high temperatures. This conversion requires a lot of energy. The most common fuels used as energy source for lime kiln are heavy fuel oil and natural gas. In a modern pulp mill lime kiln is the only user of significant amount of fossil fuels. Replacing fossil fuels with biofuels can have prominent economical and environmental benefits. Interest in using biofuels as energy source of lime kiln has become a worldwide issue in the recent years. However fuels used for lime kiln have a lot of certain requirements. The purpose of this work is to study the required characteristics from liquid fuels used in pulp mill lime kiln and to map suitable liquid biofuels already available in the markets. Also taxation of liquid biofuels compared to heavy fuel oil in Finland, Sweden and Germany is shortly introduced.

Biomedical natural language processing (BioNLP) is a subfield of natural language processing, an area of computational linguistics concerned with developing programs that work with natural language: written texts and speech. Biomedical relation extraction concerns the detection of semantic relations such as protein-protein interactions (PPI) from scientific texts. The aim is to enhance information retrieval by detecting relations between concepts, not just individual concepts as with a keyword search. In recent years, events have been proposed as a more detailed alternative for simple pairwise PPI relations. Events provide a systematic, structural representation for annotating the content of natural language texts. Events are characterized by annotated trigger words, directed and typed arguments and the ability to nest other events. For example, the sentence “Protein A causes protein B to bind protein C” can be annotated with the nested event structure CAUSE(A, BIND(B, C)). Converted to such formal representations, the information of natural language texts can be used by computational applications. Biomedical event annotations were introduced by the BioInfer and GENIA corpora, and event extraction was popularized by the BioNLP'09 Shared Task on Event Extraction. In this thesis we present a method for automated event extraction, implemented as the Turku Event Extraction System (TEES). A unified graph format is defined for representing event annotations and the problem of extracting complex event structures is decomposed into a number of independent classification tasks. These classification tasks are solved using SVM and RLS classifiers, utilizing rich feature representations built from full dependency parsing. Building on earlier work on pairwise relation extraction and using a generalized graph representation, the resulting TEES system is capable of detecting binary relations as well as complex event structures. We show that this event extraction system has good performance, reaching the first place in the BioNLP'09 Shared Task on Event Extraction. Subsequently, TEES has achieved several first ranks in the BioNLP'11 and BioNLP'13 Shared Tasks, as well as shown competitive performance in the binary relation Drug-Drug Interaction Extraction 2011 and 2013 shared tasks. The Turku Event Extraction System is published as a freely available open-source project, documenting the research in detail as well as making the method available for practical applications. In particular, in this thesis we describe the application of the event extraction method to PubMed-scale text mining, showing how the developed approach not only shows good performance, but is generalizable and applicable to large-scale real-world text mining projects. Finally, we discuss related literature, summarize the contributions of the work and present some thoughts on future directions for biomedical event extraction. This thesis includes and builds on six original research publications. The first of these introduces the analysis of dependency parses that leads to development of TEES. The entries in the three BioNLP Shared Tasks, as well as in the DDIExtraction 2011 task are covered in four publications, and the sixth one demonstrates the application of the system to PubMed-scale text mining.

The conventional activated sludge processes (CAS) for the treatment of municipal wastewater are going to be outdated gradually due to more stringent environmental protection laws and regulations. The Membrane bioreactors (MBRs) are the most promising modern technology widely accepted in the world of wastewater treatment due to their highly pronounced features such as high quality effluent, less foot print and working under high MLSS concentration. This research project was carried out to investigate the feasibility and effectiveness of MBR technology compare to the CAS process based on the scientific facts and results. The pilot scale MBR pilot plant was run for more than 150 days and the analysis results were evaluated. The prime focus of the project was to evaluate the correlation of permeate flux under different operating MLSS concentrations. The permeate flux was found almost constant regardless of variations in MLSS concentrations. The removal of micropollutant such as heavy metals, PCPPs, PFCs, steroidal hormones was also studied. The micropollutant removal performance of MBR process was found relatively effective than CAS process. Furthermore, the compatibility of submerged membranes within the bioreactor had truly reduced the process footprint.

In my PhD Thesis, I study the conceptions and representation of emotions in medieval 13th and 14th-century Iceland. I have used Icelandic saga literature as my source material and Icelandic Family sagas (Íslendingasögur) as my main sources. Firstly, I wished to explore in my study the medieval Icelandic folk theory of emotions: what emotions were thought to be, from what they originated and how they operated? Secondly, in earlier research it has been shown that emotions were seldom described in Íslendingasögur. They were mostly represented in dialogue, poetry or in somatic changes (e.g. turning pale). Consequently, I examined whether medieval Icelanders had alternative emotion discourses in literature, in addition to the usual manner of representation. My study consists of qualitative case studies, and I have analysed the sources intertextually. I suggest that medieval Icelanders regarded emotions as movements of the mind. The mind existed in the heart. As a consequence, emotions were considered physical in nature. The human body and therefore also the human mind was considered porous: if the mind of the person was not strong enough, supernatural agents and forces could penetrate theboundaries of his/her body as winds or sharp projectiles. Correspondingly, minds of strong-willed people could penetrate the minds of others. As a result, illness and emotions could upspring. People did not always distinguish between emotions and physical illnesses. Excessive emotions could cause illness, even death. Especially fear, grief and emotions of moral responsibility (e.g. guilt) made people vulnerable to the supernatural influence. Guilt was considered part of the emotional experience of misfortune (ógæfa), and in literature guilt could also be represented as eye pain that was inflicted upon the sufferer by a supernatural agent in a dream. Consequently, supernatural forces and beings were part of the upspring of emotions, but also part of the representation of emotions in literature: They caused the emotion but their presence also represented the emotional turmoil in the lives of the people that the supernatural agents harassed; emotions that had followed from norm transgressions, betrayal and other forms of social disequilibrium. Medieval readers and listeners of the Íslendingasögur were used to interpreting such different layers of meaning in texts.
