The bedrock of old crystalline cratons is characteristically saturated with brittle structures formed during successive superimposed episodes of deformation and under varying stress regimes. As a result, the crust effectively deforms through the reactivation of pre-existing structures rather than by through the activation, or generation, of new ones, and is said to be in a state of 'structural maturity'. By combining data from Olkiluoto Island, southwestern Finland, which has been investigated as the potential site of a deep geological repository for high-level nuclear waste, with observations from southern Sweden, it can be concluded that the southern part of the Svecofennian shield had already attained structural maturity during the Mesoproterozoic era. This indicates that the phase of activation of the crust, i.e. the time interval during which new fractures were generated, was brief in comparison to the subsequent reactivation phase. Structural maturity of the bedrock was also attained relatively rapidly in Namaqualand, western South Africa, after the formation of first brittle structures during Neoproterozoic time. Subsequent brittle deformation in Namaqualand was controlled by the reactivation of pre-existing strike-slip faults.In such settings, seismic events are likely to occur through reactivation of pre-existing zones that are favourably oriented with respect to prevailing stresses. In Namaqualand, this is shown for present day seismicity by slip tendency analysis, and at Olkiluoto, for a Neoproterozoic earthquake reactivating a Mesoproterozoic fault. By combining detailed field observations with the results of paleostress inversions and relative and absolute time constraints, seven distinctm superimposed paleostress regimes have been recognized in the Olkiluoto region. From oldest to youngest these are: (1) NW-SE to NNW-SSE transpression, which prevailed soon after 1.75 Ga, when the crust had sufficiently cooled down to allow brittle deformation to occur. During this phase conjugate NNW-SSE and NE-SW striking strike-slip faults were active simultaneous with reactivation of SE-dipping low-angle shear zones and foliation planes. This was followed by (2) N-S to NE-SW transpression, which caused partial reactivation of structures formed in the first event; (3) NW-SE extension during the Gothian orogeny and at the time of rapakivi magmatism and intrusion of diabase dikes; (4) NE-SW transtension that occurred between 1.60 and 1.30 Ga and which also formed the NW-SE-trending Satakunta graben located some 20 km north of Olkiluoto. Greisen-type veins also formed during this phase. (5) NE-SW compression that postdates both the formation of the 1.56 Ga rapakivi granites and 1.27 Ga olivine diabases of the region; (6) E-W transpression during the early stages of the Mesoproterozoic Sveconorwegian orogeny and which also predated (7) almost coaxial E-W extension attributed to the collapse of the Sveconorwegian orogeny. The kinematic analysis of fracture systems in crystalline bedrock also provides a robust framework for evaluating fluid-rock interaction in the brittle regime; this is essential in assessment of bedrock integrity for numerous geo-engineering applications, including groundwater management, transient or permanent CO2 storage and site investigations for permanent waste disposal. Investigations at Olkiluoto revealed that fluid flow along fractures is coupled with low normal tractions due to in-situ stresses and thus deviates from the generally accepted critically stressed fracture concept, where fluid flow is concentrated on fractures on the verge of failure. The difference is linked to the shallow conditions of Olkiluoto - due to the low differential stresses inherent at shallow depths, fracture activation and fluid flow is controlled by dilation due to low normal tractions. At deeper settings, however, fluid flow is controlled by fracture criticality caused by large differential stress, which drives shear deformation instead of dilation.

Tässä tutkielmassa tarkastellaan sanaleikkien kääntämistä amerikkalaisen animaatiosarja South Parkin suomen- ja saksankielisissä DVD-tekstityksissä. Tutkielman tavoitteena on selvittää, miten hyvin sanaleikit säilyvät tekstityskäännöksessä, ja vaikuttaako tekstityskieli sanaleikkien säilymiseen. Tutkin, mitä eri sanaleikkityyppejä lähtö- ja kohdekielissä esiintyy, ja miten eri sanaleikkityyppejä on käännetty suomessa ja saksassa. Lisäksi vertailen, millaisia käännösstrategioita suomen- ja saksankielisissä tekstityksissä on käytetty sanaleikkien kääntämiseen. Tutkimusaineistona on South Parkin kolmelta tuotantokaudelta kerätyt englanninkieliset sanaleikit ja niiden suomen- ja saksankieliset käännökset. Tutkimuksen sanaleikit jaetaan kielellisten ominaisuuksien perusteella viiteen yläkategoriaan, jotka jakautuvat yhteensä neljääntoista alakategoriaan. Sanaleikit perustuvat joko fonetiikkaan (homofonia, paronymia ja foneettinen jäljittely), morfologiaan (yhdistellyt sanat, keksityt sanat, sananmukaisuus ja sanarajoilla leikittely), semantiikkaan (homonymia, polysemia, kaksikieliset sanaleikit ja sanojen väärinkäyttö), syntaksiin (syntaktinen homonymia) tai pragmatiikkaan (muunnellut alluusiot ja sanonnat sekä kuva tukee yhtä tulkintaa). Lisäksi osassa sanaleikeissä yhdistyy useampi sanaleikkityyppi. Englanninkielisestä tutkimusaineistosta löytyi yhteensä 58 sanaleikkiä, joista oli säilynyt suomenkieliseen tekstitykseen 36 ja saksankieliseen 34. Näin ollen alkuperäisestä sanaleikkimäärästä säilyi suomenkielisiin tekstityksiin 62,1 %, ja saksankielisiin 58,6 %. Oletuksenani oli, että sanaleikeistä häviäisi noin puolet, joten hypoteesini toteutui. Ero suomen ja saksan välillä on kuitenkin niin pieni, ettei sen perusteella voida vetää johtopäätöstä siitä, onko kohdekielellä ollut merkitystä sanaleikkien käännettävyyteen. Saksan ja englannin kielisukulaisuus ei vaikuttanut vastoin ennakko-odotuksia suuresti sanaleikkien säilymiseen, eikä myöskään sillä ollut merkitystä, mitä käännösmetodia – tekstitystä vai dubbausta – kohdekulttuurissa yleensä käytetään. Sitä vastoin sanaleikkityyppi vaikutti tutkituissa kohdekielissä sanaleikkien käännettävyyteen. Tutkimusaineistossa käytettyjä käännösstrategioita oli yhteensä kuusi. Tutkimuksestani selvisi, että strategioiden määrät ja suhteelliset osuudet jakaantuivat hyvin samalla tavalla molemmissa kielissä. Sekä suomessa että saksassa yleisin käännösstrategia oli sanaleikkityypin säilyttäminen, ja toiseksi eniten oli käytetty sanaleikin sivuuttamista. Kolmanneksi käytetyin käännösstrategia molemmissa kielissä oli sanaleikin korvaaminen retorisella tehokeinolla. Sanaleikin kopiointi oli saksassa neljänneksi ja suomessa viidenneksi yleisin käännösstrategia, ja sanaleikkityypin muuttaminen suomessa neljänneksi ja saksassa viidenneksi käytetyin käännösstrategia. Sanaleikkikohdan poisto oli suomenkielisissä tekstityksissä vähiten käytetty käännösstrategia, ja saksassa sitä ei ollut käytetty kertaakaan.

The present world energy production is heavily relying on the combustion of solid fuels like coals, peat, biomass, municipal solid waste, whereas the share of renewable fuels is anticipated to increase in the future to mitigate climate change. In Finland, peat and wood are widely used for energy production. In any case, the combustion of solid fuels results in generation of several types of thermal conversion residues, such as bottom ash, fly ash, and boiler slag. The predominant residue type is determined by the incineration technology applied, while its composition is primarily relevant to the composition of fuels combusted. An extensive research has been conducted on technical suitability of ash for multiple recycling methods. Most of attention was drawn to the recycling of the coal combustion residues, as coal is the primary solid fuel consumed globally. The recycling methods of coal residues include utilization in a cement industry, in concrete manufacturing, and mine backfilling, to name few. Biomass combustion residues were also studied to some extent with forest fertilization, road construction, and road stabilization being the predominant utilization options. Lastly, residues form municipal solid waste incineration attracted more attention recently following the growing number of waste incineration plants globally. The recycling methods of waste incineration residues are the most limited due to its hazardous nature and varying composition, and include, among others, landfill construction, road construction, mine backfilling. In the study, environmental and economic aspects of multiple recycling options of thermal conversion residues generated within a case-study area were studied. The case-study area was South-East Finland. The environmental analysis was performed using an internationally recognized methodology — life cycle assessment. Economic assessment was conducted applying a widely used methodology — cost-benefit analysis. Finally, the results of the analyses were combined to enable easier comparison of the recycling methods. The recycling methods included the use of ash in forest fertilization, road construction, road stabilization, and landfill construction. Ash landfilling was set as a baseline scenario. Quantitative data about the amounts of ash generated and its composition was obtained from companies, their environmental reports, technical reports and other previously published literature. Overall, the amount of ash in the case-study area was 101 700 t. However, the data about 58 400 t of fly ash and 35 100 t of bottom ash and boiler slag were included in the study due to lack of data about leaching of heavy metals in some cases. The recycling methods were modelled according to the scientific studies published previously. Overall, the results of the study indicated that ash utilization for fertilization and neutralization of 17 600 ha of forest was the most economically beneficial method, which resulted in the net present value increase by 58% compared to ash landfilling. Regarding the environmental impact, the use of ash in the construction of 11 km of roads was the most attractive method with decreased environmental impact of 13% compared to ash landfilling. The least preferred method was the use of ash for landfill construction since it only enabled 11% increase of net present value, while inducing additional 1% of negative impact on the environment. Therefore, a following recycling route was proposed in the study. Where possible and legally acceptable, recycle fly and bottom ash for forest fertilization, which has strictest requirements out of all studied methods. If the quality of fly ash is not suitable for forest fertilization, then it should be utilized, first, in paved road construction, second, in road stabilization. Bottom ash not suitable for forest fertilization, as well as boiler slag, should be used in landfill construction. Landfilling should only be practiced when recycling by either of the methods is not possible due to legal requirements or there is not enough demand on the market. Current demand on ash and possible changes in the future were assessed in the study. Currently, the area of forest fertilized in the case-study are is only 451 ha, whereas about 17 600 ha of forest could be fertilized with ash generated in the region. Provided that the average forest fertilizing values in Finland are higher and the area treated with fellings is about 40 000 ha, the amount of ash utilized in forest fertilization could be increased. Regarding road construction, no new projects launched by the Center of Economic Development, Transport and the Environment in the case-study area were identified. A potential application can be found in the construction of private roads. However, no centralized data about such projects is available. The use of ash in stabilization of forest roads is not expected to increased in the future with a current downwards trend in the length of forest roads built. Finally, the use of ash in landfill construction is not a promising option due to the reducing number of landfills in operation in Finland.
