Abstract:
The Svecofennian Domain of the Fennoscandian Shield constitutes a considerable volume of Palaeoproterozoic crustal growth, 2.1–1.86 Ga ago, in between the Archaean craton in the NE and the 1.85–1.65 Ga Transscandinavian Igneous Belt (TIB) in the south and west. The Bergslagen area is a classical ore province located in the southwestern part of the Svecofennian Domain of south-central Sweden. Its northern part is dominated by volcanic and plutonic rocks of a magmatic arc with continental affinity, while the SE part is made up by a sedimentary basin. The Bergslagen area shows a metamorphic zonation from lower to middle amphibolite facies in the north to upper amphibolite facies and locally granulite facies in the south; a small greenschist area exists in the west. Identifying the age spectra of inherited components, magmatic crystallization, as well as metamorphic episodes, provide important constraints on the geodynamic evolution of this centrally located piece of the Shield.U–Pb zircon SIMS data presented in this paper complement the previous, regionally scattered TIMS data from this area. Magmatic zircons from two felsic metavolcanic rocks and two amphibolites (metagabbros) yield 1888±12, 1892±7 and 1887±5, 1895±5 Ma, respectively; i.e. within the 1.91–1.86 Ga range previously obtained for Early Svecofennian magmatism in Bergslagen. An augen gneiss from southern Bergslagen, assigned to the earliest TIB generation, yield an intrusive age of 1855±6 Ma. Metamorphic monazites from the same rock indicate that deformation and elevated thermal activity prevailed 1.83–1.82 Ga ago (TIMS). Metamorphic zircons in high-grade metasedimentary rocks from the south and west yield ages of 1793±5 and 1804±10 Ma, in accordance with ages for regional peak metamorphism and migmatite formation found elsewhere in the southern Svecofennian province of Sweden. More importantly, a few zircon crystals and overgrowths in rocks from the north indicate an early metamorphic episode at c. 1.87 Ga, indicating that Bergslagen has experienced two major metamorphic events. Detrital and inherited zircons span the range 2.78–1.90 Ga, with an apparent gap at 2.45–2.1 Ga, which further emphasize previous observations of a major juvenile (<2.1 Ga) and a minor Archaean provenance. This, and in particular the 1.94–1.91 Ga crystals present in the c. 1.89 Ga amphibolites, support the suggestion of a former Palaeoproterozoic pre-1.91 Ga crust in the Bergslagen area.

Abstract:
The Rare Earth Element (REE) mineralizations are not so “rare” in Sweden. They normally occur associated and hosted within granitic crystalline bedrock, and in mineral deposits together with other base and trace metals. Major REE-bearing mineral deposit types are the apatite-iron oxide mineralizations in Norrbotten (e.g., Kiruna) and Bergslagen (e.g., Grängesberg) ore regions, the various skarn deposits in Bergslagen (e.g., Riddarhyttan-Norberg belt), hydrothermal deposits (e.g., Olserum, Bastnäs) and alkaline-carbonatite intrusions such as the Norra Kärr complex and Alnö. In this study, analytical data of samples collected from REE mineralizations during the EURARE project are compared with bedrock and till REE geochemistry, both sourced from databases available at the Geological Survey of Sweden. The positive correlation between REE composition in the three geochemical data groups allows better understanding of REE distribution in Sweden, their regional discrimination, and genetic classification. Data provides complementary information about correlation of LREE and HREE in till with REE content in bedrock and mineralization. Application of principal component analysis enables classification of REE mineralizations in relation to their host. These results are useful in the assessment of REE mineral potential in areas where REE mineralizations are poorly explored or even undiscovered.

AbstractIn the Gåsborn area, West Bergslagen, central Sweden, Fe-rich, indium-bearing (0.1–2.0wt.% In) sphalerite is replaced by Fe-poor sphalerite containing minute inclusions of chalcopyrite, roquesite and an unnamed In-Zn-rich phase. Fe-rich, In-bearing sphalerite is primary; indium occurs as a roquesite molecule in solid solution. Fe-poor sphalerite, roquesite, chalcopyrite and the unnamed In-Zn-rich phase were formed from In-bearing sphalerite by secondary processes, characterized by the so-called ‘chalcopyrite disease’.

Abstract:
The efficiency of simian virus 40 (SV40) DNA replication is dependent on the structural organization of the regulatory region. The enhancing effect of the G + C-rich 21-base-pair (bp) repeats on SV40 DNA replication is position and dose dependent and to some extent orientation dependent. The inverted orientation is about 50% as effective as the normal orientation of the 21-bp repeat region. Movement of the 21-bp repeat region 180 or 370 bp upstream of the ori sequence abolishes its enhancing effect, whereas no replication is detected if the 21-bp repeat region is placed downstream of the ori sequence. The dose-dependent enhancement of the 21-bp repeat of SV40 DNA replication as first described in single transfection by Bergsma et al. (D. J. Bergsma, D. M. Olive, S. W. Hartzell, and K. N. Subramanian, Proc. Natl. Acad. Sci. USA 79:381-385, 1982) is dramatically amplified in mixed transfection. In the presence of the 21-bp repeat region, the 72-bp repeat region can enhance SV40 DNA replication. In the presence of the 21-bp repeats and a competitive environment, the 72-bp repeat region exhibits a cis-acting inhibitory effect on SV40 DNA replication.

Abstract:
The aim of this study was to assess the environmental effects of Moshyttan, one of the earliest known blast furnaces in Europe (ca. 11th century). The study was based on the analysis of three lake records in the immediate surroundings of the smelter. Fickeln lies directly downstream and is the main recipient of waterborne pollution. Mosjökälla lies directly upstream and served as the main water reservoir for the water-powered bellows. Kramptjärnen lies 1 km to the NW in a separate catchment and acts as a reference. The data includes 31 elements analyzed by X-ray fluorescence spectroscopy (XRF), organic content inferred from loss on ignition (LOI), biogenic silica (BSi) modeled from Fourier-transform infrared spectroscopy (FT-IRS) for all lakes and diatom counts for Fickeln. Two other studies provided dating of slag from the smelter and pollen- and geochemical data from Fickeln. The results show that the metallurgy and associated activities (e.g. agriculture, forest grazing and charcoal production) led to eutrophication and alkalization in Fickeln. This is indicated by the diatom community that in the background is dominated by benthic genera indicative of oligotrophy and dystrophy (Frustilia, Brachisyra and Eunotia) that during the active smelter phase is replaced by pelagic genera indicative of eutrophy (Aulacoseira and Asterionella). BSi also decreases after smelter establishment, which speculatively could indicate an overall decrease in diatom production. At the same time, a suite of elements commonly associated with iron processing (Fe, Pb and Zn) increase in the sediment.

Abstract:
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.

Abstract:
This paper briefly summarizes Bergslagen as a bedrock province in order to give background to the genesis and presence of REE-bearing minerals (short for Rare Earth Elements) in the region. These mineralizations mainly occur along the REE-line, a line aproximately a hundred kilometers in length between Norberg in the north and Nora in the south with a width of a few kilometers. Situated in the southwest of Bergslagen it is currently one of only a few places in Sweden where REE-bearing iron oxide mineralizations are potentially economically viable for mining. Ore microscopy has been conducted in order to characterize an ore sample from Myrbacksfältet, one of few sulphide rich iron oxide mineralizations within the REE-line. Additionally, an electron microscope analysis of a sample from Stålklockan, a suspected REE-bearing mineralization also within the REE-line was confirmed by EDS (short for Energy Dispersive Spectrum) analysis. An interactive map has been made of the REE- line to aid with visualization in an attempt to collect all known geospatial-, mineral-  and bedrock information in one place. The map is available in PDF format in conjunction with this text. A static version of this map is presented under 4.1 (REE-linjen).
Berggrundsprovinsen Bergslagens regionala geologi beskrivs inledningsvis för att ge bakgrund till de fyndigheter av REE-förande mineral (eng. Rare Earth Elements; Sällsynta jordartsmetaller) som förekommer utmed en ungefär hundra kilometer lång och ett par kilometer bred zon. Detta geografiskt och mineralogiskt avgränsade område kallas REE-linjen och ligger i sydvästra Bergslagen. I detta område mellan Norberg i norr och Nora i söder finns idag några av de få potentiellt ekonomiskt brytbara fyndigheterna av REE-förande mineral i Sverige vilket har gjort en kartkonstruktion vari spatiell-, mineralogisk-, och berggrundsdata över området finns sammanställd meningsfull.

Abstract:
The purpose of this master thesis is to investigate what the users/visitors do at the Filipstads Bergslags Library when they are there. The questions we asked were "What do the visitors do when they are at the library?" and "How do the visitors give priority to the librarys services?" From these two questions we asked a third "How do the visitors view the library and its functions and what function do they see as the most important to them?" The method we used was a user study and we did this at the request of the management at the library. A questionnaire was constructed and handed out in a pilot study. We made some changes in the questionnaire before we started to hand it out at the library. We received a total of 224 questionnaires during a two week period. We found that most of the visitors were very traditional in their tasks at the library. They borrowed books and other media and read newspapers and magazines. When we classified our findings in gender, age groups, highest education and occupation we found that men read more newspapers and magazines than women do. They, on the other hand, borrow more books than men and they also visited the library more often. Only 25% of the visitors used the library computers. Most of the participants in the study showed a low interest in the various arrangements and conveniences the library offered. The visitors were only interested in a few cultural arrangements such as author evenings. The two library functions that really stood out were the cultural function and the information function. Our conclusions are that the visitors at Filipstads Bergslags library are very traditional in their activities and that they look upon the library as a cultural and informational institution.

Abstract:
Abstract This thesis explores early modern industrial dynamics and especially the long-term performance of iron production and its localisation in Central Sweden during the period 1368-1910. Iron production, iron export and localisation in a national perspective as well as the regional industrial development in Central Sweden during the period 1805-1910 are studied. The production and localisation changes of the industry in the early modern period were investigated by processing easily available but scattered data. The study of the iron industry in the period 1805-1910 was based census data on employment structure in the Central Swedish parishes in four benchmark years, 1805, 1855, 1890 and 1910 and was carried out with the help of statistical cluster analysis. The first important result is that the Swedish iron export increased rapidly in the 16th the 17th centuries. This had to do with the breakthrough of bar iron which soon replaced the old form of iron called osmund iron. The export continued to increase up to the 1740s. From the 1740s there was stagnation till the 1820s when an expansion commenced and in the rest of the period under study the export grew fourfold. The distribution of iron production showed variations as to geographical patterns over time and there were rather distinct chronological phases as well. An expansion of established ironworks and tilthammers commenced in the end of the 16th century and reached its highest annual average in the 1630s. The localisation of new establishments in the 16th and early 17th centuries was mainly concentrated to the interior of Central Sweden. The localisation became more and more scattered over the country in the early modern period. Thus, the tendency towards diffusion outside the administrative Bergslagen became more and more obvious in the 18th century with new ironworks and tilthammers in Northern and Southern Sweden. In the late 19th century the number of industrial parishes had increased and so had the share of employed in manufacturing industry. Furthermore, the industrial parishes were concentrated to a large cluster which covered the inner parts of Central Sweden. However, the analysis of industrial branches also showed a diversification where the wood, paper and pulp industries and above all the metal industries were fast growers. The metal industries also proved a geographical closeness to the traditional iron and steel industry The second main outcome of the investigation has to do with the continuity concerning the localisation of the iron industry. The historical continuity and the confinement to a certain area are evident from the analyses of various localisation factors in which a number of logit-models were employed. The status of a parish as industrial at one time point was to a great extent decisive for its status as industrial at a later date. The existence of iron ore mining in the parish and if the parish was situated inside the institutional region of Bergslagen also enhanced the probability for it to be defined as an industrial community also long after the institutional regulation had been abolished in the 1850s. In a long-term perspective, the analysis revealed that there was a marked continuity between the early modern patterns of localisation of the iron industry and the localisation of the engineering industrial firms in the 20th century. However, the early modern localisation did not show a significant connection with the industrial parishes’ localisation in 1855, 1890 and 1910, which means that the results are not unambiguous. The third main result of the study is that geographical vicinity of communities to others with industrial activities contributes to industrial growth. In this way industrial communities tend to concentrate geographically and thereby to form clusters. For 1855 this was not significant but for 1890 it was evident. For 1910 it was shown that if a parish had more than one neighbouring industrial community, the probability of its being industrial was great. In a long-term perspective it seems that agglomerations of industrial activities form an environment which can cope with episodes of increasing transformation pressure in a better way than isolated units. Geographical concentrations which, historically seen, are characterised by “industry in the air” have a high propensity to adapt to changes in the industrial environment.

Abstract:
By understanding which factors that affect individuals´ will to share knowledge with others within an organization, companies can successfully develop a knowledge-based culture by influencing individuals´ attitudes and behaviour concerning knowledge sharing. Several researchers claim that intrinsic motivational factors can consistently facilitate knowledge sharing between individuals within an organization. Other researchers also assert that extrinsic motivational factors, such as reward systems, might affect individuals’ motivation to share knowledge. However, extrinsic motivational factors´ impact on knowledge sharing is a relatively unexplored field and more empirical studies are sought after. From this starting point this study is aimed, by conducting a case study of Länsförsäkringar Bergslagen (LF), to explore whether, and if so how, the reward system which applies to the sales force of private insurances at LF affects their motivation to share work-related knowledge with each other. The results of the study show that the reward system does not, in any distinguishable way, affect knowledge sharing between members of the sales force. Instead knowledge sharing, to a great extent, happens automatically due to the fact that the sales force enjoys sharing knowledge with each other. In this way they help each other to achieve their goals which brings about a sense of mutual satisfaction.

Full text
Abstract:
Sphalerite is, apart from being the main global source of zinc (Zn), also one of the main source for the critical elements indium (In), gallium (Ga) and germanium (Ge), which can be extracted as by-products during Zn mining. In the westernmost part of the Palaeoproterozoic Bergslagen ore province, Sweden, In-anomalies have been reported from sulphide mineralizations. These In-anomalies can be attributed to either pre-ore formation crustal processes manifested by the local (Svecofennian, c. 1.87-1.89 Ga) syn-volcanic mineralisations, or to epigenetic metasomatic events primarily related to younger (c. 1.80-1.79 Ga) granitoids. In this study, sphalerite samples from 19 different mineralisations in westernmost Bergslagen were examined by both electron probe microanalyzer (EPMA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), in order to firstly, measure trace element concentrations, and especially those of the critical element In, Ga and Ge, and secondly, to apply this information to gain new information on the trace element inventory and incorporation mechanisms of sphalerite. The dataset also allows for testing the ore-formation process models, not least in cases of elevated In-contents. Utilization of these two analytical methods also provided the opportunity for a direct spot-to-spot comparison of their performance in detecting trace element concentrations in sphalerite. The results verify the In-enrichment of the area, whereas Ga and Ge only follow crustal abundancies. The concentrations of the other trace elements vary significantly, even at a sample scale. The compositional variation shows several patterns between certain elements, suggesting that their incorporation in the sphalerite lattice was allowed via substitution mechanisms (e.g. In3++(Cu+,Ag+)↔2Zn2+; Fe2++Cd2++Mn2+↔3Zn2+; Cu++Mn2++In3+↔3Zn2+). In contrast, some measured high Cd, Ag and Pb concentrations are attributed to nano (or micro) inclusions of primarily galena. Other elements such as As, Sn, Sb, Se, Au, Tl, Ni, Te and Mo yielded, in almost all the samples, concentrations below the detection limit for both analytical methods. Discrimination methods based on trace element concentrations and distribution of the In-enriched mineralizations suggest that the In-anomalies are most likely related to Svecofennian volcanic to subvolcanic hydrothermal processes, forming mineralisations that were later modified during the Svecokarelian orogeny. Finally, the direct comparison of EPMA results to that of LA-ICP-MS, showed the significantly better performance of the latter method in detecting trace-level concentrations, provided that a proper calibration procedure has been followed.
Sulfidmineralet zinkblände är, förutom att vara den huvudsakliga globala källan för zink (Zn), också ett av de viktigaste värdmineralen för de kritiska metallerna indium (In), gallium (Ga) och germanium (Ge), vilka kan utvinnas som viktiga biprodukter vid zinkbrytning. I den västligaste delen av malmprovinsen Bergslagen i Mellansverige har In-anomalier rapporterats från flera mineraliseringar. Dessa lokala In-anrikningar kan tillskrivas antingen processer verksamma innan och under den vulkaniska aktiviteten, eller senare geologiska händelser relaterade till yngre graniter. I denna studie har zinkblände från 19 olika mineraliseringar i västra Bergslagen karakteriserats med två olika system för mikrokemisk analys; elektronmikrosond (EPMA) och laserablativ induktivt kopplad plasma-masspektrometri (LA-ICP-MS). Detta har gjorts för att mäta spårelementhalter, och särskilt då för de kritiska metallerna In, Ga och Ge. Genom att använda dessa två metoder parallellt gavs också möjligheten till direkta jämförelser mellan dem vad gäller deras kapacitet för spårelementanalys av zinkblände. Resultaten verifierar att detta område är anomalt In-anrikat, medan halterna av Ga och Ge är låga och endast följer genomsnittshalterna för kontinental jordskorpa. Halterna av de övriga spårelementen varierar avsevärt, även på individuell provskala, och visar i flera fall systematiska mönster mellan vissa element. Dessa mönster tyder på att deras införlivande i zinkbländestrukturen gått via flera specifika utbytes-(substitutions-)mekanismer (t.ex. In3++ (Cu+, Ag+) ↔2Zn2+; Fe2+ + Cd2++ Mn2+ ↔3Zn2+, Cu++ Mn2++ In3+ ↔3Zn2+). Däremot kan förhöjda halter av Cd, Ag och Pd tillskrivas nano- (eller mikro-) inneslutningar av framförallt blyglans. Andra element, som As, Sn, Sb, Se, Au, TI, Ni, Te och Mo uppvisade halter under detektionsgränserna för båda analysmetoderna i nästan alla undersökta prov. Bildningsmässiga (genetiska) diskrimineringsmetoder baserade på spårelementhalter kombinerat med de geologiska och spatiella relationerna för de In-anrikade mineraliseringarna tyder på att de senare bildades genom svekofenniska vulkanisk-hydrotermala processer och därefter modifierats under svekokarelsk bergskedjebildning. Slutligen, i den direkta jämförelsen av EPMA gentemot LA-ICP-MS, visade den senare metoden signifikant bättre kapacitet för spårämnesanalys, förutsatt att ett korrekt kalibreringsprotokoll har följts.

Abstract:
Bakgrund: Det finns många kartlagda hälsoeffekter av fysisk aktivitet, bland annat minskar risken för hjärt- och kärlsjukdomar, högt blodtryck, cancer och metabola sjukdomar. Motivation kan beskrivas genom self-determination theory (SDT) som delar upp motivation i inre och yttre faktorer. En individ rör sig mellan ett kontinuum av motivationsfaktorer. Den inre motivationen är associerad med ett längre bibehållande av en aktivitet. En skillnad i motivationsfaktorer mellan idrottsutövare och motionärer har setts i tidigare studier. Det är intressant ur ett hälsopromotivt perspektiv att kunna identifiera vad som motiverar studenter till fysisk aktivitet. Syfte: Syftet med studien var att beskriva motivationsfaktorer för vardagsmotion respektive bergsbestigning hos studenter. Metod: Kvalitativa semistrukturerade intervjuer genomfördes med fyra studenter som bestigit Kebnekaises västra led någon gång de senaste tre åren. Materialet analyserades genom kvalitativ innehållsanalys. Resultat: Materialet från intervjuerna resulterade i fem kategorier: Välbefinnande för hela kroppen, Lust till aktivitet, Vänners uppmuntran, Få en gemensam upplevelse samt Testa sina gränser. Varje kategori representerade en viktig motivationsfaktor. Två av motivationsfaktorerna var gemensamma för såväl vardagsmotion som bergsbestigning. Konklusion: Motivationsfaktorerna skiljde sig åt beroende på aktivitet. Välbefinnande för hela kroppen representerar en motivationsfaktor för vardagsmotion. Motivationsfaktorerna Lust till aktivitet och Vänners uppmuntran var någotsom representerade både vardagsmotion och bergsbestigning. Faktorer som enbart sågs hos bergsbestigning hos informanterna var Få en gemensam upplevelse och Testa sina gränser. Det fanns även skillnad i motivationsfaktorer beroende på erfarenhet; mindre erfarna motiverades av att testa sina gränser och mer erfarna av att dela upplevelsen med andra.
