This thesis examines the intersection between lithium extraction and contemporary art through a visual semiotic analysis of three contemporary artworks: Unknown Fields’ We Power Our Future With the Breast Milk of Volcanoes, Marcela Magno’s Land [2] Litio, and Julian Charrière’s Future Fossil Spaces. It explores how lithium extraction is visualised in the selected artworks, what connotations can be extracted from them, the geopolitical dimension expressed in them, and how they relate to the myth of ‘green’ transition. This text takes a starting point in the notion of critical visualisations of extractivism in contemporary art as an urgent political, artistic, and ecological issue. Extractivism is a crucial concept in this thesis, and it is further explored through the intersection of art and extractivism in dialogue with previous research by, for example, Eray Çaylı, Macarena Gómez-Barris, and T.J. Demos. The artworld’s interest in lithium has grown in the last years, with cultural projects and exhibitions on lithium taking place in Sweden and the Netherlands, yet there are no academic texts that explore the intersection of lithium extraction and contemporary art. The aim of this thesis is to thoroughly examine this intersection through three contemporary artworks, to expand academic literature regarding this topic, but also to make the results available to curators, cultural workers, and artists who are currently developing cultural projects around lithium and its extraction. The results of the visual semiotic analysis demonstrated that all three of the artworks critically engaged with lithium extraction by visibilising either present or future green sacrifice zones. They all countered the myth of ‘green’ transition with different strategies: by showing the two-furthermost-apart links in the lithium supply chain, by recuperating Indigenous creation myths of the extracted landscapes, and by exploring the supposed intangibility of our ever-expanding digital world.

Artificial Intelligence in Automotive Industry / Cost reduction is one of the main concerns in industry. Companies invest considerably for better performance in end-of-line fault diagnosis systems. A common strategy is to use data obtained from existing instrumentation. This research investigates the challenge of learning from historical data that have already been collected by companies. Machine learning is basically one of the most common and powerful techniques of artificial intelligence that can learn from data and identify fault features with no need for human interaction. In this research, labeled sound and vibration measurements are processed into fault signatures for vehicle starter motors and alternators. A fault detection and identification system has been developed to identify fault types for end-of-line testing of motors. However, labels are relatively difficult to obtain, expensive, time consuming and require experienced humans, while unlabeled samples needs less effort to collect. Thus, learning from unlabeled data together with the guidance of few labels would be a better solution. Furthermore, in this research, learning from unlabeled data with absolutely no human intervention is also implemented and discussed as well. / Thesis / Master of Applied Science (MASc)

English speakers use the concept of "darkness" in a number of metaphors to portray a wide variety of experiences from evil to fear to ignorance. These metaphorical connections or entailments are so natural that we can see an image of a dark-clad person in a film or book and usually be correct in assuming that they are at best questionably moral and at worst a villain. The Old Testament (OT) also employs dark images and dark imagery to various effects. From Job's description of the underworld in Job 3 to Isaiah 's description of the coming light that will dispel the darkness in Isa 8- 9, to the dark paths the wicked trod in Eccl 2:14, the OT uses a number of metaphors of darkness. For most of these examples, it would be easy to assume that the ancient Hebrew writers of the OT were working with the same concepts of darkness that we do today and thus interpret these passages along the same lines as our own modem English metaphors. But such assumptions can and have led to a number of misunderstandings and conflicting interpretations of passages that employ dark images. These miscommunications are most apparent in passages where God's presence is indicated by darkness like at the Sinai and Temple theophanies (Exod 20:19-20 and 1 Kgs 8:12, respectively) as well as later poetry about God (Ps 97:2). By combining the theoretical framework of Cognitive Metaphor Theory (CMT), and the methodology of Conceptual Blending (CB), this study will work toward a clearer understanding of how the writers of the OT understood darkness and how that shaped their use of it in their images and imagery of death, captivity, the unknowable, and God. It will be shown that the ancient Hebrew conception and use of darkness centres around three key recurring metaphors - Death is Darkness, Captivity is Darkness, and the Unknown is Darkness - while the metaphor Evil is Darkness is foreign to the OT. These findings serve to provide greater clarity in interpreting those OT passages that portray God as having a penchant for darkness.

Syftet med denna uppsats var att undersöka om det är möjligt att förutse var de okända fångstgropar befinner sig i landskapet med hjälp av karaktärsdragen från de kända lämningarna. Målet med detta arbete är att identifiera och registrera okända fångstgropar för att skydda dem från att skadas av skogsbruket. Denna studie förhåller sig till ett undersökningsområde (kommunerna Karlskoga och Degerfors) men diskuterar även andra fångstgropar i Sverige. Under detta arbete har de kända fångstgroparna nyttjats på flera olika sätt; med hjälp av terrängskuggning granskades området vid fångstgroparna i syfte att se om det fanns ytterligare gropar i närheten samt att studera hur en grop kunde synas i terrängskuggningen. Sedan fältbesöktes de kända fångstgroparna för att kunna sammanställa deras karaktärsdrag och med hjälp av detta, samt tidigare forskning och kartanalyser kunde fem karaktärsdrag uppmärksammas. I slutändan upptäcktes åtta okända fångstgropar, varav tre är kvalitetssäkrade av Ulf Eriksson, arkeolog på Skogsstyrelsen och är/kommer bli registrerade i Kulturmiljöregistret. Uppsatsen diskuterar också det nuvarande kunskapsläget om fångstgropar till olika bytesdjur, samt jakt- och fångstmetoderna vargskall och varggård. Detta har dessvärre inte kunnat nå en slutsats då det fanns alldeles för många osäkra faktorer i tidigare forskning som påverkade uppsatsen negativt. / This paper aims to investigate whether it is possible to predict the location of the unknown pits in the landscape using the characteristics of the known remains. The goal of this work is to identify and register unknown pitfalls to protect them from being damaged by forestry. This study relates to an investigation area (the municipalities of Karlskoga and Degerfors) but also discusses other catch pits in Sweden. During this work, the known catch pits have been used in several different ways; with the help of terrain shading, the area at the trapping pits was examined to see if there were additional pits nearby and to study how a pit could be seen in the terrain shading. The known trapping pits were then visited in the field to be able to compile their characteristics. With the help of previous research and map analyses, five characteristics could be noticed. In the end, seven unknown trap pits were discovered, three of which are quality assured by Ulf Eriksson, archaeologist at the Swedish Forest Agency. The thesis also discusses the current state of knowledge about trapping pits for various prey animals, as well as the hunting and trapping methods wolf hunting and wolf enclosure. Unfortunately, this has not been able to reach a conclusion as too many uncertain factors in previous research affected the essay negatively.

Background: About five to 10% of cancers in the head and neck region are neck squamous cell carcinoma of unknown primary (NSCCUP). Their diagnosis and treatment are challenging given the risk of missing occult tumors and potential relapse. Recently, we described human papillomavirus (HPV)-related NSCCUP-patients (NSCCUP-P) as a subgroup with superior survival. However, standardized diagnostic workup, novel diagnostic procedures, decision-making in the multidisciplinary tumor board (MDTB) and multimodal therapy including surgery and post-operative radio-chemotherapy (PORCT) may also improve survival. Methods: For assessing the impact of standardized diagnostic processes simultaneously established with the MDTB on outcome, we split our sample of 115 NSCCUP-P into two cohorts treated with curative intent from 1988 to 2006 (cohort 1; n = 53) and 2007 to 2018 (cohort 2; n = 62). We compared diagnostic processes and utilized treatment modalities applying Chi-square tests, and outcome by Kaplan–Meier plots and Cox regression. Results: In cohort 2, the standardized processes (regular use of [18F]-FDG-PET-CT imaging followed by examination under anesthesia, EUA, bilateral tonsillectomy and neck dissection, ND, at least of the affected site) improved detection of primaries (P = 0.026) mostly located in the oropharynx (P = 0.001). From 66.0 to 87.1% increased ND frequency (P = 0.007) increased the detection of extracapsular extension of neck nodes (ECE+) forcing risk factor-adapted treatment by increased utilization of cisplatin-based PORCT that improved 5-years progression-free and overall survival from 60.4 and 45.3 to 67.7% (P = 0.411) and 66.1% (P = 0.025). Conclusions: Standardized diagnostic workup followed by ND and risk-factor adapted therapy improves survival of NSCCUP-P.

Die Systematische Toxikologische Analyse (STA) stellt auf Grund der großen Vielfalt und der ständigen Zunahme an toxikologisch relevanten Substanzen eine der größten Herausforderungen in der chemischen Analyse dar. In der vorliegenden Arbeit wurde daher die Eignung der Flüssigchromatographie in Kombination mit der Hybrid-Quadrupol-Flugzeitmassenspektrometrie (LC-QTOF-MS) für diesen Zweck untersucht. Dazu wurden eine Datenbank mit über 7360 und eine CID-Spektrenbibliothek mit mehr als 2720 toxikologisch relevanten Substanzen erstellt und geeignete Probenvorbereitungsmethoden entwickelt. Die Erprobung der Methoden erfolgte an dotierten Blut- und Haarproben. Hierbei zeigte sich, dass die Analyse im Auto-MS/MS-Modus (Messzyklen von MS- und MS/MS-Spektren) eine Identifizierung basischer Substanzen mittels CID-Spektren zwischen 0,5 und 2 ng/ml im Blut ermöglichte. Die Nachweisgrenzen der für 24 Wirkstoffe validierten Methode in Haaren lagen bei 3 bis 15 pg/mg. Die Eignung der LC-QTOF-MS zur STA von Haarproben wurde an 30 Drogentodesfällen und 60 Todesfällen mit bekannter chronischer Medikamenteneinnahme zu Lebzeiten sowie an 77 Blutproben nachgewiesen. Für die Suche nach Metaboliten wurde ein Metaboliten-Tool entwickelt. In der praktischen Anwendung auf Datenfiles von Blut- und Haarproben erwies sich das Tool als wertvolles Hilfsmittel zur Identifizierung unbekannter Peaks und zur Bestätigung von Suchergebnissen in der Datenbank. Zur automatischen Konzentrationsabschätzung identifizierter Substanzen wurde ein Tool „Estimate Concentration“ geschaffen. Die Überprüfung des Verfahrens an realen Blut- und Haarproben durch Vergleich mit HPLC-DAD- und GC-MS-Ergebnissen wies eine gute Übereinstimmung der Konzentrationen auf. Insgesamt zeigten die Untersuchungen, dass die LC-QTOF-MS zurzeit die am besten geeignete Methode für die STA darstellt. Auch bei einem erst später aufkommenden Verdacht kann eine gezielte Suche in dem bereits gemessenen Datenfile durchgeführt werden. / Due to the large variety and the steady increase of toxicologically relevant substances, systematic toxicological analysis (STA) is one of the most difficult tasks in analytical chemistry and, therefore, a steady topic of research and methodical improvement. For this reason, the suitability of liquid chromatography in combination with hybrid quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) for STA was investigated. For this purpose, a database of more than 7360 and a CID spectra library of more than 2720 toxicologically relevant substances and suitable methods for sample preparation were developed. The application was evaluated at spiked blood and hair samples. It was found that the analysis in Auto-MS/MS mode (alternating measurement cycles of MS and MS/MS spectra) allowed substance identification in blood using CID spectra between 0.5 and 2 ng/ml for basic substances. The detection limits of the validated method in hair ranged from 3 to 15 pg/mg for 24 drugs. The suitability of LC-QTOF-MS for STA was tested for hair samples from 30 drug-related death cases and from 60 death cases with known chronic medication as well as for 77 blood samples. For the search of metabolites, a metabolite tool was developed. In the practical application to data files from blood and hair samples, the tool proved to be very helpful for identification of unknown peaks and for confirmation of results obtained only from the database without CID spectra. A tool "Estimate Concentration" was created for automatic estimation of concentrations of identified substances. The application to real blood and hair samples and the comparison of the concentrations with results from HPLC-DAD and GC-MS showed good agreement. Overall, these investigations showed that LC-QTOF-MS is currently the most favorable method for STA. Because of the comprehensive registration of all substances in a sample, the data files can be checked for the presence of certain poisons even later without new measurements.

Ce travail a comme objectif d‘analyser la voix et le silence dans l‘œuvre fragmentaire de deux écrivains, Fernando Pessoa (1888-1935) et Maurice Maeterlinck (1862-1949), héritiers de plusieurs cultures, auteurs dont l‘écriture gagne un surplus de sens grâce aux voix qu‘elle crée et qui font entendre leurs mots ou bien le silence de leur absence.A travers l‘analyse de quelques-unes de leurs oeuvres, nous essayons de comprendre jusqu‘à quel point ces deux poètes, rattachés aux mouvements moderniste et symboliste, vécurent l‘inquiétude propre à leur siècle, réfléchissant sur les raisons qui les menèrent à transformer la vie en un éternel mouvement vers l‘absolu, une quête d‘un état d‘âme impossible en dehors de leur création poétique ou théâtrale. Nous tenterons ainsi de justifier, dans la mesure du possible, la forme inachevée d‘une grande partie de leurs écrits, marqués par la dépersonnalisation et le questionnement concernant l‘énigme de l‘existence.Fernando Pessoa et ses hétéronymes seront les voix (im)possibles dans le silence de Maeterlinck, deux formes d‘une même polyphonie, placée en rapport avec la fragmentation formelle des personnages des oeuvres de chacun des auteurs. / This work pretends to analyse voice and silence having in mind the fragmentation of Fernando Pessoa (1888-1935) and Maurice Maeterlinck‘s (1862-1949) work, heirs to several cultures and owners of a writing where the meaning of words depend on the voices or on the silence of their absence.Through some of their works, we try to understand how these poets of symbolism and modernism lived the disquietude of a century, to analyse the causes that made them change life into an eternal movement in direction of the absolute, looking for a state of soul, only possible in their poetry and theatre, and justify, whenever possible, the infinite form that determined the unaccomplishement of most of their writings, which they developped together with the depersonalization and the irreducibility that caracterizes the enigma of life.Fernando Pessoa and his heteronymous are the (im)possible voices in Maeterlinck‘s silence, two forms of the same polyphony, in relation with the formal fragmentation of the characters of their works. / Este trabalho tem como objectivo analisar a voz e o silêncio na fragmentação da obra de dois autores, Fernando Pessoa (1888-1935) e Maurice Maeterlinck (1862- 1949), herdeiros de várias culturas e donos de uma escrita em que as palavras ganham sentido pelas vozes a que dão corpo ou pelo silêncio da sua ausência.Através da apreciação de algumas das suas obras, tentamos compreender até que ponto estes dois poetas do modernismo e do simbolismo viveram a inquietude de um século, reflectir sobre os motivos que os levaram a transformar a vida num eterno movimento em direcção ao absoluto, na busca de um estado de alma só possível no acontecer da sua poesia ou teatro e justificar, sempre que possível, a forma infinita que definiu o inacabamento de grande parte dos seus escritos, desenvolvidos a par com uma despersonalização e a irredutibilidade que caracteriza o enigma da existência.Fernando Pessoa e os seus heterónimos são as vozes (im)possíveis no silêncio de Maeterlinck, duas formas de uma mesma polifonia, colocada em relação com a fragmentação formal das personagens nas obras de cada um dos autores.

Barnamordsplakatet (a Infanticide Proclamation) of 1778 was a circular allowing unmarried mothers to give birth at an undisclosed location without giving up the name of the father. The proclamation was supposed to ease the situation for the unwed mother in Sweden. The aim was to investigate whether women in Assembly of Hällefors, far from government and close to remote forest Finnskogen, was affected by the Infanticide Proclamation, between 1771 and 1830. Case studies has been done on people who had illegitimate children, if they were convicted, what the crime was and what the punishment was. The investigation is made at a local level and compared against national analyzes on the same theme. A lot of illegitimate children were born in Grythyttan nearby and slightly less in Hällefors, compared to other places of Sweden. Mothers and fathers were convicted in the district court for crimes, including, sexual intercourse between unmarried persons. More women than men were convicted. The cases in court with convicted for the second time, was culminating between 1800 and 1810. Infanticide Proclamation is immediately adapted in court. People's behavior changed before the law took effect when the amount of born illegitimate children outnumbered the amount of convicted mothers.
