The aim of this study is to gain a better understanding of the structure and the deformation history of a NW-SE trending regional, crustal-scale shear structure in the Åland archipelago, SW Finland, called the Sottunga-Jurmo shear zone (SJSZ). Approaches involving e.g. structural geology, geochronology, geochemistry and metamorphic petrology were utilised in order to reconstruct the overall deformation history of the study area. The study therefore describes several features of the shear zone including structures, kinematics and lithologies within the study area, the ages of the different deformation phases (ductile to brittle) within the shear zone, as well as some geothermobarometric results. The results indicate that the SJSZ outlines a major crustal discontinuity between the extensively migmatized rocks NE of the shear zone and the unmigmatised, amphibolite facies rocks SW of the zone. The main SJSZ shows overall dextral lateral kinematics with a SW-side up vertical component and deformation partitioning into pure shear and simple shear dominated deformation styles that was intensified toward later stages of the deformation history. The deformation partitioning resulted in complex folding and refolding against the SW margin of the SJSZ, including conical and sheath folds, and in a formation of several minor strike-slip shear zones both parallel and conjugate to the main SJSZ in order to accommodate the regional transpressive stresses. Different deformation phases within the study area were dated by SIMS (zircon U-Pb), ID-TIMS (titanite U-Pb) and 40Ar/39Ar (pseudotachylyte wholerock) methods. The first deformation phase within the ca. 1.88 Ga rocks of the study area is dated at ca. 1.85 Ga, and the shear zone was reactivated twice within the ductile regime (at ca. 1.83 Ga and 1.79 Ga), during which the strain was successively increasingly partitioned into the main SJSZ and the minor shear zones. The age determinations suggest that the orogenic processes within the study area did not occur in a temporal continuum; instead, the metamorphic zircon rims and titanites show distinct, 10-20 Ma long breaks in deformation between phases of active deformation. The results of this study further imply slow cooling of the rocks through 600-700ºC so that at 1.79 Ga, 2 the temperature was still at least 600ºC. The highest recorded metamorphic pressures are 6.4-7.1 kbar. At the late stages or soon after the last ductile phase (ca. 1.79 Ga), relatively high-T mylonites and ultramylonites were formed, witnessing extreme deformation partitioning and high strain rates. After the rocks reached lower amphibolite facies to amphibolite-greenschist facies transitional conditions (ca. 500-550ºC), they cooled rapidly, probably due to crustal uplift and exhumation. The shear zone was reactivated at least once within the semi-brittle to brittle regime between ca. 1.79 Ga and 1.58 Ga, as evidenced by cataclasites and pseudotachylytes. In summary, the results of this study suggest that the Sottunga-Jurmo shear zone (and the South Finland shear zone) defines a major crustal discontinuity, and played a central role in accommodating the regional stresses during and after the Svecofennian orogeny.

A total of over 200 different samples of bark and wood of Silver birch, Norway spruce and Scots pine were analysed. Samples were taken from several areas in western Finland, some with known sources of atmospheric heavy metal emission (Harjavalta, Ykspihlaja). Also analytical data for pine needles from some sites are reported. The chemical analyses were performed by thick-target particle-induced X-ray emission (PIXE) spectrometry after preconcentration by dry ashing of samples at 550oC. The following elements were quantified in most of the samples: P, S, K, Ca, Mn, Fe, Ni, Cu, Zn, Rb, Sr, Cd, Ba and Pb. The ash percentage and the chemical composition of ashes of different wood materials were also obtained, as dry ashing was used in the analytical procedure. The variations in elemental concentrations in wood and bark of an individual tree, expressed as RSDs, were mostly in the range 10 – 20 %. For several trees of the same species sampled from small areas (< 1 ha), the variations in elemental concentrations were surprisingly high (RSDs 20 – 50 %). In the vicinity of metal plants, effects of strong atmospheric heavy metal pollution (pollution factor above 100) were observed in pine bark. The increase of heavy metal content in wood samples from the same sites was quite small. Elemental concentrations in ashes of bark and wood, from areas with no local source of atmospheric pollution, were relatively uniform. Based on this observation an alternative way of demonstrating atmospheric pollution of tree bark is discussed.

The purpose of the METKU Project (Development of Maritime Safety Culture) is to study how the ISM Code has influenced the safety culture in the maritime industry. This literature review is written as a part of the Work Package 2 which is conducted by the University of Turku, Centre for Maritime Studies. The maritime traffic is rapidly growing in the Baltic Sea which leads to a growing risk of maritime accidents. Particularly in the Gulf of Finland, the high volume of traffic causes a high risk of maritime accidents. The growing risks give us good reasons for implementing the research project concerning maritime safety and the effectiveness of the safety measures, such as the safety management systems. In order to reduce maritime safety risks, the safety management systems should be further developed. The METKU Project has been launched to examine the improvements which can be done to the safety management systems. Human errors are considered as the most important reason for maritime accidents. The international safety management code (the ISM Code) has been established to cut down the occurrence of human errors by creating a safety-oriented organizational culture for the maritime industry. The ISM Code requires that a company should <i>provide safe practices in ship operation and a safe working environment and establish safeguards against all identified risk.i> The fundamental idea of the ISM Code is that companies should continuously improve safety. The commitment of the top management is essential for implementing a safety-oriented culture in a company. The ISM Code has brought a significant contribution to the progress of maritime safety in recent years. Shipping companies and ships’ crews are more environmentally friendly and more safety-oriented than 12 years ago. This has been showed by several studies which have been analysed for this literature research. Nevertheless, the direct effect and influence of the ISM Code on maritime safety could not be isolated very well. No quantitative measurement (statistics/hard data) could be found in order to present the impacts of the ISM Code on maritime safety. In this study it has been discovered that safety culture has emerged and it is developing in the maritime industry. Even though the roots of the safety culture have been established there are still serious barriers to the breakthrough of the safety management. These barriers could be envisaged as cultural factors preventing the safety process. Even though the ISM Code has been effective over a decade, the old-established behaviour which is based on the old day’s maritime culture still occurs. In the next phase of this research project, these cultural factors shall be analysed in regard to the present safety culture of the maritime industry in Finland.

Kungliga Akademin i Åbo var verksam mellan åren 1640 och 1827. Det finns en omfattande samling dissertationer från den tiden vid akademibiblioteket. Samlingen är inte fullständig. Samlingen har tillkommit genom gåvor från både Sverige och Finland. De svenska universitetsbiblioteken sände frikostigt dupletter från sina samlingar, och från tryckerihistoriska biblioteket på Skansen kom betydande mängder gammalt åbotryck. Bland privata välgörare kan nämnas professor Artur Rindell, generalkonsul Axel Solitander och generalkonsul Sven A. Lovén, men framför allt en svensk donator, löjnant Thore Virgin, en av Sveriges mest betydande boksamlare under 1900-talet. Han bidrog med en betydande kollektion, och ställde därtill en penningsumma för antikvariska förvärv till bibliotekets förfogande. Samlingen är okatalogiserad, men de tryck som ingår är förprickade i ett referensexemplar av Vallinkoski, Jorma Turun akatemian väitöskirjat 1642-1828. Helsinki 1828. En presentation av samlingen återfinns på bibliotekets hemsida, http://bibbild.abo.fi/diss/dissaml.htm Samlingen omfattar totalt 3.249 volymer.

Samlingen med signum HB Vb4a-b finns vid huvudbiblioteket och innehåller litteratur om Finlands och Sveriges historia till och med år 1999. Vid Humanistiska biblioteket finns en historisk samling i anslutning till ämnet Historia. Från och med år 1919 har samlingen av finländsk historisk litteratur utökats genom friexemplarsrätten. Ett systematiskt anskaffande genom köp av nordiskt historiskt material har inneburit att beståndet av svensk historisk litteratur är omfattande. Biblioteket emottog under första hälften av 1900-talet såväl från hemlandet som från Sverige talrika donationer innehållande historisk litteratur. Bland donationerna bör några verkligen betydande och speciella samlingar nämnas. Professor Ernst Estlander donerade en stor, sällsynt och fullständig samling av tryckta, hektograferade eller på annat sätt mångfaldigade politiska skrifter från ofärdsåren i Finland 1899-1905. Likaså ingår tryck och urklipp om ofärdsåren i Lithanderska samlingen. I bägge specialsamlingarna ingår material som inte har katalogiserats. En specialsamling benämnd Schaumanska samlingen donerades av kammarrådet Carl Schauman och hans son publicisten August Schauman. Samlingen innehåller mycket gammal litteratur från olika ämnesområden, också nordisk historia. Specialsamlingen är katalogiserad i kortkatalog. Litteraturen i samlingen söks i Alma med sökfunktionen Signum och söktermen HB Vb4a-b. En del litteratur tryckt före 1980 söks manuellt i den systematiska kortkatalogen, men retroaktiv inmatning i Alma av litteratur tryckt mellan 1830 och 1979 pågår. Från och med år 2000 ingår litteraturen vid huvudbiblioteket om Finlands och om Sveriges historia i en numerus currens-samling. Litteraturen vid hela akademibiblioteket från och med nämnda år fås genom ämnesordssökning.
