    Biosphere assessment forms one of the main components in Posiva's Safety Case portfolio and includes analyses of terrain and ecosystem development. Shoreline displacement and changes in surface hydrology form one part of these analyses. In this report, the regional development of the Olkiluoto-Pyhaejaervi area in the time period 2000 BP - 8000 AP was examined by taking into account changes in the surface flow patterns of the Lapinjoki and Eurajoki river basins. A hydrological model, EULA, was developed and applied to investigate the past and future hydrological regimes and changes in the Olkiluoto-Pyhaejaervi study area. As detailed assessment of erosion and sedimentation effects were not within the scope of this study, only their general effects were evaluated. The digital elevation models (DEM) for different time stages (2000, 1500, 1000 and 500 BP; 100, 300, 500, 1000, 1500, 2000, 2500, 3000, 3500, 4000, 4500, 5000, 6000, 7000 and 8000 AP) were compiled taking into account the land uplift and tilting of the Earth's crust. With the aid of various sophisticated GIS tools, the boundaries of the main river basins, the flow patterns of rivers and development of lakes during each stage were modelled. The yearly discharge rates of rivers Eurajoki and Lapinjoki were also evaluated with the assumption that present climatic features prevail during the whole time period 2000 BP - 8000 AP. Finally, the probability of significant changes in the surface water flow routes were estimated during different stages. (orig.)

The results of gravimetric surveys have indicated that the margin of the Eurajoki stock slopes westward underneath the site, but to depths in excess of 3000 m. Plate tectonic reconstructions of the Precambrian of Finland, partly based on the results of major deep seismic sounding experiments, such as the international GGT/SVEKA project (along a NE-SW transect through the Satakunta area), indicate the pelitic and psammitic migmatite belts in Satakunta represent parts of the early Proterozoic Southern Finland and Central Finland continental arcs, respectively. Collision of these arc complexes took place 1890 - 1880 Ma ago, when the rocks were deformed and metamorphosed for the first time. The highT/lowP metamorphism was caused by mafic underplating, which led to a strong increase in temperature, and recrystallisation and partial remelting of the rocks in the upper crust. The collision of the arc complexes is characterised by an intense magmatic activity, which appears as synorogenic granitoids.

Rapakivi granites and related mafic rocks were generated in an anorogenic extensional regime by partial melting of the upper mantle and lower crust.

    In October 2012, the geological mapping of investigation trench OL-TK19 was carried out by the Geological Survey of Finland at the Olkiluoto study site. The SE-NW trending, ca. 85 m long trench is located in the central part of the Olkiluoto Island next to investigation trenches OL-TK18 and OL-TK4. The lithology in investigation trench OL-TK19 is of heterogeneous character, with rock type varying from veined gneiss, diatexitic gneiss to pegmatitic granite, along with portions of mica gneiss and K-feldspar porphyritic gneiss. In addition, inclusions of mica gneiss, quartz gneiss and skarn are encountered. The rocks have been subjected to a multiphase ductile deformation and the trench is situated in an area where the latest ductile deformation phase, D4 prevails. The investigation trench can be divided into three domains according to its dominant deformation phase and foliation; the eastern part of the trench is dominated by the D3 deformation phase whereas the middle and western parts are dominated by the D4 deformation phase. The S3 foliation has a more ENE-WSW oriented direction whereas the S4 is trending NE-SW. In addition to this difference in orientation, the different structural signature of these two deformation types is observed, the S3 foliation is defined by smaller scaled granitic leucosome veining whereas the S4 foliation is intensely sheared and have a schistose character. During the fracture mapping, all fractures intersecting the central thread were investigated and a total of 132 fractures were recorded. The average fracture frequency 1.53 fractures/m. On the basis of fracture orientations, three fracture sets can be defined. The first set is vertical and NW-SE trending, second set strikes NE-SW with a moderate dip towards the SE and the third set is vertical and NE-SW trending. The median fracture length is 1.38 m and most fractures do not exceed 0.5 m in length, the longest measured fracture being 5.30 m in length. Fracture fillings are mostly

    and associated granitic leucosome veining usually strike NE-SW and dip gently to the southeast (the mean dip/dip direction is 38/158 deg). The foliation gradually turns from NE-SW striking in the southern part of the trench to E-W striking in the northern part. No pre-D 2B structures were identified in the OL-TK9. The leucosome veins show isoclinal D 2 folds in places. During the third deformation phase (D 3 ), the isoclinal F2 folds of the mica gneiss and the granite leucosome veins were refolded by F 3 folding mainly producing small-scale, tight folds with fold axis moderately plunging towards east and rarely to the west. During the fracture mapping, all fractures intersecting the central thread were measured. Dip direction and dip, rock type, length, form, undulation, character, aperture, and infilling if present were recorded for each fracture. A total of 1197 fractures were measured including several fracture clusters (cluster = many identical fractures in a small area). The mean fracture density of the trench is 3.23 fractures/m. From the fracture orientation data, three different fracture sets were interpreted: Set (I) fractures dip gently to the south-southeast, set (II) fractures dip steeply to the east or west, and set (III) fractures dip moderately towards the north. Partly due to the width of the trench most fractures have trace length less than two metres. Most fractures (51,4 %) are open or partially open and 32.4 % of the fractures have infillings. Fracture infillings include chlorite, calcite, kaolinite, epidote, pyrite, illite, mica minerals, quartz, Fe-oxide (hematite), and soil. Several deformation zone intersections were observed in the investigation trench. Four Brittle Joint cluster Intersections (parallel to the foliation), one N-S striking Brittle Fault zone Intersection, one Semi-brittle Fault zone Intersection, and one N-S striking Ductile Shear zone Intersection intersect the trench.

    Changes in the geochemical environment in crystalline bedrock fractures were investigated using the stable isotopes of C, O and S in fracture filling minerals as tracers. Of special interest were the possible changes which may occur in the subsurface at low temperatures. Especially, the influence of microbial activity was recognized as a catalyst for inducing changes in the geochemical environment. The study site is the Olkiluoto island located on the western coast of Finland, planned to host a geological repository for nuclear waste. Fracture surfaces were investigated to recognize the latest mineralizations at the site. These fillings were comprised of thin plates or small euhedral crystals of calcite and pyrite. The carbon and sulfur isotope compositions of calcite and pyrite were measured from bulk material by conventional IRMS, and in situ by secondary ion mass spectrometry. A notable feature of the late-stage fillings was high variabilities in the δ13C values of calcite and the δ34S values of pyrite, which ranged from -53.8 ‰ to +31.6 ‰ and from -50.4 ‰ to +77.7 ‰, respectively. Based on the isotopic compositions of the fillings, several features in the past hydrogeochemical environment could be recognized. The isotopic composition of the fracture fillings indicate an environment which was stratified with respect to depth. Characteristic features include bacterial sulfate reduction (BSR) occurring at depths 50 m. It appears that methanic conditions were replaced by sulfate reduction at depths >50 m likely due to infiltration of SO42--rich brackish waters. Sulfate reducing bacteria used mainly surface derived organic carbon as electron donors. Some indication of minor methanotrophic activity was recognized in anomalously low δ13C values of calcite, down to -53.8 ‰, at the depth range of 34-54 m. This methanotrophic activity may have been related to bacteria using CH4 as an electron donor in BSR.

    Survey of Finland at the Olkiluoto study site, Eurajoki, as part of Posiva Oy's site investigation programme for the development of an underground repository for nuclear waste. The E-W striking, ca. 55 m long trench is located in the central part of the Olkiluoto Island adjacent to investigation trenches OL-TK12 and OL-TK4. The trench was cleaned with a pressure washer and pressurized air. The rock types were determined macroscopically. The rock types in investigation trench OL-TK18 is of heterogeneous character, with a large variation in their composition. The rocks vary from tonalitic-granodioritic gneiss to diatexitic gneiss, with portions of K-feldspar porphyritic gneiss. Inclusions of mica gneiss and a well-preserved schollen migmatite is encountered. The trench ends in a feldspar-rich pegmatoid. The most dominant tectonic feature is D{sub 4} ductile deformation domain and associated S{sub 4} foliation. This domain and hence the S{sub 4} foliation is striking NE-SW with a moderate dip towards SE. Both ends of the trench are dominated by the earlier deformation phase, showing S{sub 3} foliation striking ENE-WSW and roughly dipping towards the S. The S{sub 3} foliation is associated with small-scaled granitic leucosome veining, while the S{sub 4} foliation have a schistose character and it is more sheared. D{sub 4} ductile deformation domain is also characterised by a sheared blastomylonitic rock having growth of roundish feldspar porphyroblasts and BTschlierens indicating high alteration of the protolith. During the fracture mapping, all fractures intersecting the central thread were investigated and a total of 117 fractures were recorded. The average fracture frequency of the trench is 2.11 fractures/m. On the basis of fracture orientations one main set can be distinguished striking NE-SW (foliation parallel) with a moderate dip towards the SE. The median fracture trace length is 1.6 m and over half of the fractures exceed 1.5 m trace length, the longest

    The projects aimed at improving nuclear and radiation safety in areas adjacent to Finland have been compiled into one programme. The purpose of the programme is to promote activities that minimise accident risks at nuclear power plants and that improve preparedness for situations involving a risk. Nuclear materials are also to be kept under strict control. In the last few years, nuclear and radiation safety has clearly improved in areas adjacent to Finland. But work is still needed to reduce the remaining risks. The Finnish support programme comprises two very definite functions. On one hand, the programme acts as a catalyst for projects launched by the Russians themselves or by the Western partners together, and strives to pave the way for international financing projects. On the other hand, assistance is given as direct support for certain hand-picked projects. (orig.)

    In the study area of Romuvaara, investigations have been carried out during 1987 - 90 with the aim of finding out whether the polyphasically deformed Precambrian gneiss complex is suitable for the final disposal of spent nuclear fuel. The bedrock has been studied by geological, geophysical, geohydrological and geochemical methods. Airborne, ground and borehole geophysical surveys were used in studying the rock type distribution, fracturing and hydraulic conductivity of the bedrock to a depth of one kilometre. Airborne surveys (magnetic, radiometric and two electromagnetic methods) and ground surveys (VLF and VLF-R, magnetic and soil radar methods) were useful in distinguishing the metadiabases, amphibolites and granodiorites from the less magnetized migmatites. The electromagnetic and seismic refraction surveys were used in locating crushed and fractured zones. The rock type distribution was studied by single-hole logging of susceptibility, natural γ radiation and radiometric γ-γ -density. Electrical and acoustic logging served the mapping of fractures and the interpretation of water injection tests. The flow conditions in the boreholes were studied by fluid logging and tube-wave sounding. The rock volume surrounding the boreholes was mapped by borehole radar with a frequency of 22 MHz. The upper parts of the boreholes were also studied by vertical radar profiling (VRP). Larger volumes of rock were mapped by vertical seismic profiling (VSP) using 4 - 5 transmitter shotholes per borehole

    Illite K-Ar age determinations were done on five fault breccia samples from the ONKALO underground research facility, Olkiluoto, Eurajoki, S-W Finland. The XRD, SEM, and TEM studies and K-Ar analyses were done in John deLaeter Center in Mass Spectrometry at Curtin University, Perth, Western Australia. The <2 micron grain size fractions contain illite, chlorite, dickite, and quartz. All fractions had minor contamination phases comprising mainly of quartz but traces of K-feldspar contamination could be identified in all samples. The authigenic illite shows variable K concentrations. The illite contents of the ONK-PL68 and ONK-PL87 samples are the smallest. The K-Ar ages for the <2 micron fractions vary from ∼0.55 Ga to 1.38 Ga. The sample ONKPL68 yields a K-Ar age of 912 ± 18 Ma corresponding to a Neoproterozoic-Tonian age. This age can be roughly temporally linked with late events related to Sveconorwegian orogeny. Sample ONK-PL87 has a K-Ar age of 550 ± 11 Ma corresponding to a Neoproterozoic - Lower Cambrian age. The samples ONK-PL522 and ONK-PL901 sampled from the storage hall fault show identical K-Ar ages of 1385 ± 27 Ma and 1373 ± 27 Ma, respectively. These correspond to a Mesoproterozoic-Ectasian age related to Subjotnian or Postjotnian events. ONK-PL960 yields a K-Ar age of 1225 ± 24 Ma corresponding to a Mesoproterozoic-Ectasian age. This age agrees well with the ages from Postjotnian diabase dykes in W Finland. The 2-3 % detrital K-feldspar contamination in clay fractions increases the age. Especially for the youngest sample ONK-PL87, the effect may be geologically meaningful as after the correction the age clearly indicates Caledonian events. Moreover, the age for the low K sample ONKPL901 shifts to indicate Postjotnian diabase age. (orig.)

    Olkiluoto is an island of ca. 10 km 2 in area on the coast of the Botnian Bay and separated from the mainland by a narrow strait. The Olkiluoto nuclear power plant, with two reactors in operation and a third one under construction, and the underground repository for low and intermediate waste are located in the western part of the island. The repository for spent fuel will be constructed in the central part of the island at a depth of between 400 and 600 m. The suitability of Olkiluoto as a location for a spent fuel repository has been investigated over a period of 20 years by means of extensive ground- and air-based methods and shallow and deep drillings. In a regional context, Olkiluoto is located within a bedrock area, covering approximately 800 million years of geological history of the Precambrian Fennoscandian Shield. The oldest part of the bedrock consists of supracrustal, metasedimentary and metavolcanic rocks deformed and metamorphosed during the Palaeoproterozoic Svecofennian orogeny ca. 1900-1800 million years ago. They are mostly migmatised, high-grade metamorphic mica gneisses, containing cordierite, sillimanite or garnet porphyroblasts. Plutonic rocks consisting of trondhjemites, tonalites, granodiorites, coarse-grained granites and pegmatites intrude the supracrustal rocks. The Mesoproterozoic anorogenic Laitila rapakivi batholith, dated at 1583 ±3 Ma, is located in the central part of the region. The Eurajoki rapakivi stock, located 5 km east of Olkiluoto, is a satellite massif to the Laitila batholiths. After the rapakivi magmatism the geological evolution of the area continued with the deposition of the Satakunta sandstone. The upper parts of the sandstone were deposited ca. 1400-1300 Ma ago, but the development of the sedimentation basin (graben) may have begun already during the rifting period, ca. 1650 Ma ago, associated with the intrusion of the rapakivi magma. The sandstone and older rocks are cut by olivine diabase dykes and sills 1270

    Geological mapping of investigation trench OL-TK14 was carried out by the Geological Survey of Finland at the Olkiluoto study site, Eurajoki, as part of Posiva Oy's site investigation programme for the development of an underground repository for nuclear waste. The E-W striking, ca. 215 m long trench is located in the eastern part of the Olkiluoto Island adjacent to boreholes OL-KR40 and OL-KR45. The trench was cleaned with a pressure washer and pressurized air. The rock types were determined macroscopically. Five samples were also investigated microscopically. The main rock type in the trench is veined gneiss. A few less than 0.5 m wide coarsegrained pegmatitic granite dykes are also encountered. Furthermore a large number of mica gneiss, quartz gneiss and skarn inclusions are present in the veined gneiss, being often elongated and parallel to the foliation. The most dominant tectonic feature is the foliation S2 and associated intense granitic leucosome veining. The foliation strikes ENE-WSW and dips steeply towards SES. Intensely to moderately banded rocks dominate the trench. The sparse F3 folds observed in OL-TK14 are small-scale tight folds in leucosome veins. A large-scale (10 m) open bending of the foliation that could be a result of D4 folding was also observed. Shearbands and other signs of ductile shearing were observed on many locations in the trench and in the eastern part there is a high-grade ductile shear zone intersection. During the fracture mapping, all fractures intersecting the central thread were investigated and a total of 684 fractures were recorded. The average fracture density of the trench is 3.18 fractures/m. On the basis of fracture orientations three main sets can be distinguished: 1) a set striking N-S with vertical dip, 2) a ENE-WSW striking set with varying dips towards the SSE (parallel to the foliation) and 3) a NE-SW striking set with sub-vertical dip towards the SE or the NW. Most of the measured fractures are short due to the

    Zircon LA-MC-ICP-MS and monazite TIMS ages have been determined for three PGR dykes (A2018, A2020, and A2070) and a KFP (A2022) from the ONKALO underground research facility, Olkiluoto, Eurajoki, SW Finland. For purposes of comparison, leucosomic PGRs (A2019, A2021, and A2023) crosscut by the PGR dykes and the KFP were also dated. Minimum ages for the PGR dykes and the A2022 KFP were determined by the monazite U-Pb ages. PGR dykes reveal partially overlapping ages of 1826 ± 7 Ma (A2018), 1811 ± 5 Ma (A2020), and 1817 ± 3 Ma (A2070). Monazite age of 1808 ± 6 Ma for the KFP is coeval with the youngest PGR dyke monazite. The ∼1.81-1.80 Ga ages for the supposed PGR dyke zircon agree within the error limits with the monazite ages. For the KFP, obvious co-magmatic zircon was not identified. The metamorphic zircon rims and domains found from the PGR dykes reveal multiphase overprinting, the ages ranging from 1.86 Ga to 1.80 Ga. Subsequently, the high-U PGR dyke zircon suffered major lead loss during the Rapakivi event at 1.58 Ga and finally, a few grains show early Devonian age of ∼400 Ma. In the KFP, many structurally homogeneous zircon domains and rims plot on a ∼1.80 Ga discordia line, while the concordant data are ∼1.83 Ga. Leucosomic PGRs A2019 and A2021 crosscut by the PGR dykes enclose 1.87-1.85 Ga zircon resembling and being contemporaneous with the tonalite zircon in the Olkiluoto area. The concordia ages of 1836 ± 13 Ma (A2019) and 1807 ± 11 Ma (A2021) for the metamorphic zircon domains in the leucosomes correlate perfectly with the supposed ages of the crosscutting PGR dykes. The youngest metamorphic zircon phases in leucosome A2023 are dated at 1.82-1.80 Ga. That is in good accordance with the monazite age 1808 ± 6 Ma from the KFP A2022 crosscutting the leucosome A2023. The samples contain also abundant older inherited zircon cores and grains. Archaean ages vary from 3.1 Ga to 2.7 Ga and the older Palaeoproterozoic between 2.1 Ga and 1.9 Ga. The

    Full Text Available Modeling tools are needed to assess (i the amounts of loading from agricultural sources to water bodies as well as (ii the alternative management options in varying climatic conditions. These days, the implementation of Water Framework Directive (WFD has put totally new requirements also for modeling approaches. The physically based models are commonly not operational and thus the usability of these models is restricted for a few selected catchments. But the rewarding feature of these process-based models is an option to study the effect of protection measures on a catchment scale and, up to a certain point, a possibility to upscale the results. In this study, the parameterization of the SWAT model was developed in terms of discharge dynamics and nutrient loads, and a sensitivity analysis regarding discharge and sediment concentration was made. The SWAT modeling exercise was carried out for a 2nd order catchment (Yläneenjoki, 233 km2 of the Eurajoki river basin in southwestern Finland. The Yläneenjoki catchment has been intensively monitored during the last 14 years. Hence, there was enough background information available for both parameter setup and calibration. In addition to load estimates, SWAT also offers possibility to assess the effects of various agricultural management actions like fertilization, tillage practices, choice of cultivated plants, buffer strips, sedimentation ponds and constructed wetlands (CWs on loading. Moreover, information on local agricultural practices and the implemented and planned protective measures were readily available thanks to aware farmers and active authorities. Here, we studied how CWs can reduce the nutrient load at the outlet of the Yläneenjoki river basin. The results suggested that sensitivity analysis and autocalibration tools incorporated in the model are useful by pointing out the most influential parameters, and that flow dynamics and annual loading values can be modeled with reasonable

    Teollisuuden Voima Oy (TVO carries out site investigations in Finland for final disposal of nuclear high level waste during 1987-2000. Investigations by geological, geophysical, geohydrological and geochemical methods were carried out in the Veitsivaara area in 1987-90 to determine the suitability of the bedrock for the final disposal of spent nuclear fuel. Airborne, ground and borehole geophysical methods were used to study the rock type distribution, fracturing and hydraulic conductivity. Airborne surveys were performed by magnetic, radiometric and two electromagnetic methods and ground investigations by VLF magnetic and resistivity, magnetic and impulse radar methods. Electromagnetic and seismic refraction surveys were used to locate crushed and fracture zones. The properties of weak electrical conductors, e.g. their depth dimensions, were studied by direct current resistivity measurements. The rock type distribution was studied by single-hole logging of susceptibility, natural γ-radiation and radiometric γ γ-density. Electrical and acoustic logging allowed water bearing fractures to be mapped and the results of water injection tests to be interpreted. Flow conditions in the boreholes were studied by both fluid logging and tube wave sounding

Samples for grain size determinations were taken from 3 vertical profiles, placed about 20-25 m apart along the trench. Two till units was sampled separately. The profiles extended from the soil surface down to bedrock. The samples were first dried in the laboratory after which they were sieved. In addition, the grain size distribution of the < 63 μm fraction was analyzed with the Sedigraph 5100 instrument. Sedimentological observations of the sampling profiles were documented in field by drawing them on a field observation form and the profiles were photographed using a digital camera. In addition, the excavated section was photographed along its whole length. The till cover in OL-TK19 consists of two parts. The surface layer of the till is oxidized, brownish grey sandy till, whereas the lower layer is unoxidized, grey silty till. Dark grey silty till as in the bottom of investigation trenches OL-TK13 and OL-TK14 was not found in this trench. The till layers in OL-TK19 was deposited in the last flow phase of the Weichselian continental ice. Bedrock striations indicate that the ice moved in a NW-SE direction. The till beds smooth bedrock topography. The tills showed no signs of disturbance related to bedrock movements. (orig.)

    The Quaternary deposits in investigation trench OL-TK17 were studied by the Geological Survey of Finland in summer 2009. Samples for grain size determinations were taken from 13 vertical profiles, placed about 25 m apart along the trench, where bedrock didn't reach surface. Profiles 5 and 6 were done by the side of the trench because of that. Each till bed was sampled separately. The profiles extended from the soil surface down to bedrock. The samples were first dried in the laboratory after which they were sieved. In addition, the grain size distribution of the < 63 μm fraction was analyzed with the Sedigraph 5100 instrument. Sedimentological observations of the sampling profiles were documented in field by drawing them on a field observation form and the profiles were photographed using a digital camera. In addition, the excavated section was photographed along its whole length. The till cover in OL-TK17 consists of two parts. The surface layer of the upper till is oxidized, brown till, whereas the lower layer is unoxidized, grey till. The lower till has been preserved in bedrock depressions. The lower till is compact, dark grey silty till with more than 19 % of clay-size material (under 0.002 mm). The upper till in OL-TK17 was deposited in the last flow phase of the Weichselian continental ice. Bedrock striations indicate that the ice moved in a WNW-ESE direction. The till beds level out the bedrock topography. Weathered, broken bedrock was found in two places at the bottom of the trench near sampling profiles 08, 09 and 10. No signs of postglacial faults were detected either in the tills or in the exposed bedrock. The tills showed no signs of disturbance related to bedrock movements, only icepressed cracks were found in the lower silty compact till over broken bedrock. (orig.)

    Brittle faults are well known as preferential conduits for localised fluid flow in crystalline rocks. Their study can thus reveal fundamental details of the physical-chemical properties of the flowing fluid phase and of the mutual feedbacks between mechanical properties of faults and fluids. Crustal deformation at the brittle-ductile transition may occur by a combination of competing brittle fracturing and viscous flow processes, with short-lived variations in fluid pressure as a viable mechanism to produce this cyclicity switch. Therefore, a detailed study of the fluid phases potentially present in faults can help to better constrain the dynamic evolution of crustal strength within the seismogenic zone, as a function of varying fluid phase characteristics. With the aim to 1) better understand the complexity of brittle-ductile cyclicity under upper to mid-crustal conditions and 2) define the physical and chemical features of the involved fluid phase, we present the preliminary results of a recently launched (micro)structural and geochemical project. We study deformed quartz veins associated with brittle-ductile deformation zones on Olkiluoto Island, chosen as the site for the Finnish deep repository for spent nuclear fuel excavated in the Paleoproterozoic crust of southwestern Finland. The presented results stem from the study of brittle fault zone BFZ300, which is a mixed brittle and ductile deformation zone characterized by complex kinematics and associated with multiple generations of quartz veins, and which serves as a pertinent example of the mechanisms of fluid flow-deformation feedbacks during brittle-ductile cyclicity in nature. A kinematic and dynamic mesostructural study is being integrated with the detailed analysis of petrographic thin sections from the fault core and its immediate surroundings with the aim to reconstruct the mechanical deformation history along the entire deformation zone. Based on the observed microstructures, it was possible to

    Geological mapping of investigation trench OL-TK13 was carried out by the Geological Survey of Finland at the Olkiluoto study site, Eurajoki, as a part Posiva Oy's site investigation programme for the development of an underground repository for nuclear waste. The east-west striking, ca. 250 m long trench is located in the vicinity of boreholes OL-KR23 and OL-KR27, ca. 250 m east of the ONKALO research facility. The mapping was performed from washed bedrock surface and rock types were determined macroscopically. The main rock types in OL-TK13 are diatexitic gneiss, veined gneiss, pegmatitic granite and K-feldspar porphyry. Mica gneiss and granite/granitized mica gneiss exist to a lesser extent. The diatexitic gneiss is the dominant rock type in the western part and the veined gneiss in the eastern part of the trench. The veined gneiss consists of pelitic mica gneiss paleosome and pegmatitic granite leucosome veins that are parallel to the foliation. In the diatexitic gneiss, the proportion of the leucosome veins and patches is over 50 % and the rock has an ambiguous texture. The pegmatitic granite also occurs as wider sections in the western part of the trench. The K-feldspar porphyry is characterized by potassium feldspar phenocrysts (diameter 4 deformation phase. The migmatitic gneisses were folded during the D 3 deformation phase resulting in small scale, tight and asymmetrical F 3 folds plunging moderately to the NE. During the fracture mapping, all fractures longer than one metre and all fractures intersecting the central thread were investigated. Measurements including orientation, length, fillings, Jr-value, Ja-value and undulation were recorded for a total of 860 fractures. The mean fracture density is 3.5 fracture/m. From the orientation data, three fracture sets were identified: (1) fractures parallel to the foliation, (2) subvertical N-S trending factures and (3) fractures dipping steeply to the N. ∼45 % of all fractures are 0.5-1.5 m in length and

    The Quaternary deposits in investigation trench OL-TK13 were studied by the Geological Survey of Finland in autumn 2006. The investigations were carried out in three phases as the excavation progressed. Samples for grain size determinations were taken from vertical profiles, placed 25 m apart along the trench. The profiles extended from the soil surface down to bedrock or, if the bedrock was covered with water, to the water table. Between 6 and 7 kg of sediment was taken in a bucket with a shovel and placed in plastic bags for transport to the laboratory. The samples were first dried in the laboratory after which they were sieved. In addition, grain size distribution of the < 63 {mu}m fraction was analyzed with the Sedigraph 5100 instrument. Sedimentological observations of the sampling profiles were documented in field by drawing on a field observation form and the profiles were photographed using a digital camera except profiles 7 and 8. In addition, the excavated section was photographed along their whole length. The length of OL-TK13 is approximately 250 m and 11 profiles were studied. The height of the profiles varied from 7.3 m to 2.3 m, with an average of 4.6 m. The till cover in OL-TK13 consist of two parts. The upper till has three layers. Surface layer is oxidized, brown sandy till, which is underlain by grayish brown intermediate layer of sandy till. This layer represents the grounwater table, which is moving up and down. The lower layer is unoxidized, grey sandy till. The thickness of the upper till varies from 2.3 to 5.5 meters. The upper till in OL-TK13 is classified as having a normal amount of cobbles and boulders with the size of the larger clasts varying from 6 to 60 cm. The edges of clasts have been eroded and rounded. The upper till has normal compactness. The lower till has been spared in bedrock depressions. Part of it's material has ascended the upper till. The lower till is compact, dark grey silty till with over 15 % of fine material

    Secondary ion microprobe zircon U-Pb ages have been determined for two tonalitic gneisses, two pegmatitic granites, and two potassium feldspar porphyry samples from the Olkiluoto study site, Eurajoki, S-W Finland. Moreover, monazites from the Kfeldspar porphyries were dated using TIMS U-Pb method. The tonalitic gneiss A1879 TTG 1 reveals bimodal zircon population and for A1880 TTG it is homogeneous. The samples yield similar overlapping concordia ages of 1851 ± 5 Ma and 1856 ± 5 Ma, respectively. The pegmatitic granite samples A1881 PGR 1 and A1883 PGR 2 have mostly zircons resembling those of the TTG's. The supposed pegmatitic zircons with high U and low Th are strongly altered. The zircon U-Pb data of A1881 PGR 1 plot roughly in two separate lines on a concordia diagram. The apparently younger ∼1.79 Ga data are all from the high U and low Th/U zircons and therefore certainly set the minimum age for the A1881 PGR 1. It is suggested, that the ∼1.85 Ga data comprise analyses from inherited zircons as it include both lower and higher Th/U zircons and 1.85 Ga coevals with age of the tonalitic gneisses. Thus, the apparent age for the A1881 PGR 1 is ∼1.79 Ga. The U-Pb data of sample A1883 PGR 2 also divide into two groups. The higher Th/U, inherited zircons determine an age of 1852 ± 9 Ma which is the same as that of the TTG's. The low Th/U zircon data scatter and the age of 1.83 Ga for A1883 PGR 2 is only poorly determined. The both potassium feldspar porphyry samples A1882 KFP 1 and A1884 KFP 2 reveal heterogeneous zircon populations. The A1882 KFP 1 zircons showing magmatic zoning in BSE images conceivably determine a concordia age of 1842± 6 Ma for the rock. In addition to that a few ∼1.9 Ga inherited zircon and metamorphic low Th/U rims with ages between 1.88 Ga and 1.83 Ga were detected. The age for the youngest metamorphic zircon rims overlaps with that of the magmatic zircons. The zircons in the other KFP sample A1884 show a wide range of ages

    Saddle-shaped reticulate Nummulites from the Early Oligocene rocks of Khari area, SW Kutch, India is reported here for the first time. Unusual shape of this Nummulites is due to the curved nature of the coiling plane, indicating space constrained postembryonic test growth. With regular development of chambers, septa and septal filaments, the saddle-shaped Nummulites constitutes the third morphotype of N. cf. fichteli Michelotti form A. Other morphotypes of the species reported earlier include inflated lenticular and conical tests. Multiple morphotypes of N. cf. fichteli form A indicates varied test growth in response to substrate conditions. Morphological variability exhibited by N. cf. fichteli form A from Kutch and some Early Oligocene reticulate Nummulites from the Far East are comparable. This faunal suite is morphologically distinct from the contemporary reticulate Nummulites of the European localities.

    Land is rising in relation to sea level several millimetres per year on the coast of southwestern Finland. The aim of the study was to gather information about the land uplift process. Sediment samples were collected from 14 lakes lying at different altitudes in the area between Olkiluoto and Lake Pyhaejaervi in southwestern Finland to study the relative sea-level changes and land uplift. The present-day lakes had once been below the waters of the Baltic, but due to uplift they had been isolated from the sea one after another. The isolation points in the sediments were determined by preliminary diatom analyses. They show the change from brackish to fresh-water conditions, and these horizons were then dated by two radiocarbon assays. (37 refs., 18 figs., 1 tab.)

    Southwest Turkey, along Mediterranean coast, is prone to large earthquakes resulting from subduction of the African plate under the Eurasian plate and shallow crustal faults. Maximum observed magnitude of subduction earthquakes is Mw = 6.5 whereas that of crustal earthquakes is Mw = 6.6. Crustal earthquakes are sourced from faults which are related with Isparta Angle and Cyprus Arc tectonic structures. The primary goal of this study is to assess seismic hazard for Antalya area (SW Turkey) using a probabilistic approach. A new earthquake catalog for Antalya area, with unified moment magnitude scale, was prepared in the scope of the study. Seismicity of the area has been evaluated by the Gutenberg-Richter recurrence relationship. For hazard computation, CRISIS2007 software was used following the standard Cornell-McGuire methodology. Attenuation model developed by Youngs et al. Seismol Res Lett 68(1):58-73, (1997) was used for deep subduction earthquakes and Chiou and Youngs Earthq Spectra 24(1):173-215, (2008) model was used for shallow crustal earthquakes. A seismic hazard map was developed for peak ground acceleration and for rock ground with a hazard level of a 10% probability of exceedance in 50 years. Results of the study show that peak ground acceleration values on bedrock change between 0.215 and 0.23 g in the center of Antalya.

    The mineralogy of atmospheric particles at the confluence of the Tinto and Odiel rivers, south of Huelva (a highly industrialized city in the SW Spain), was characterized in view to identify source origins. In spite of the small amount of sample collected, mineralogical characterization was performed by X-ray diffraction, polarized light microscopy and scanning electron microscopy with EDS analysis system, using an adequate sample preparation methodology. Sedimentable (SP) and aerosols particles were sampled an one-week basis every two months for one year. Quartz, calcite and feldspars were found to be the major minerals in both fractions, and phyllosilicates, dolomite and gypsum were also identified in lower content. Minor mineral particles included barite, apatite, sphalerite and pyrite. SEM studies revealed the additional presence of chalcopyrite in both SP and aerosols, and of chalcocite-covellite, halite and sylvite in the latter. Siderite, hematite and ankerite were only detected in the SP fraction. The concentrations of the previous minerals increased in summer by effect of the limited rain and the resulting scarcity of atmosphere washing. Non-mineral particles detected by SEM in SP and aerosol fractions included spherical, biological and compositionally complex particles. The main source of mineral particles was found to be the soil suspension in addition to the metallurgical and fertilizer production industries in the area.

    Landsat TM data were used for lithological discrimination and mapping in the little-known, semiarid 900 km 2 area around Caraculo station and the middle course of the Rio Giraul (Namibe Province, SW Angola) following two main procedures. The first of these was based on visual evaluation of three-band composites, band-ratio composites and Principal Component Analysis. The second method relied on the extraction of spectral signatures, and their use to obtain automatic classifications. Satisfactory results were reached with the first procedure, thus allowing - with limited support of ground information — the draft of a lithological map, while the second method was not systematically efficient, even for confirmation of data acquired with the first procedure. Image interpretation suggests that an extensive but hithertoun differentiated metasedimentary complex consisting of a heterogeneous supracrustal sequence should be subdivided into at least two units. Field observations proved that one of these is marked by a notable frequency of marbles and the other is characterized by a widespread occurrence of amphibolitic bodies. Moreover, a belt of undetermined (thermally metamorphosed ?) metamorphic rocks is interposed between them. The distinction of so far unidentified units, though restricted to interpretation of processed Landsat TM data, has significant geological implications also in the regional context and will be helpful in guiding future work with conventional geological methods.

    The determination of an appropriate catchment area for a hospital providing highly specialized (i.e. tertiary) health care is typically a trade-off between ensuring adequate client volumes and maintaining reasonable accessibility for all potential clients. This may pose considerable challenges, especially in sparsely inhabited regions. In Finland, tertiary health care is concentrated in five university hospitals, which provide services in their dedicated catchment areas. This study utilizes Geographic Information Systems (GIS), together with grid-based population data and travel-time estimates, to assess the spatial accessibility of these hospitals. The current geographical configuration of the hospitals is compared to a normative assignment, with and without capacity constraints. The aim is to define optimal catchment areas for tertiary hospitals so that their spatial accessibility is as equal as possible. The results indicate that relatively modest improvements can be achieved in accessibility by using normative assignment to determine catchment areas. Copyright © 2017 Elsevier Ltd.

    Estonia, Latvia, and Lithuania (the Baltic countries) and the Republic State of Carelia, Russia belong to the so-called nearby areas of Finland. All being part of the former Soviet Union, they are now undergoing the establishment of their own environment- managing systems. Finland has shown a great amount of interest in supporting the efforts of these areas to solve their environmental problems. In 1993 VTT started, at the request of the East European Project of the Finnish Ministry of the Environment, a four year project aiming at the establishment of national atmospheric emission measurement systems in the Baltic countries and the Republic state of Carelia (later: the counterpart countries). Proper national emission measurement systems were regarded important in order to provide reliable data on the emission situation for national and international use. The main target of the work is to raise the level of the emission measurements in the counterpart countries to the international level. Two aspects were considered to be required to achieve this goal; (1) delivery of proper emission measurement equipment, (2) training of the emission measurement personnel. It was estimated that within three to four years these counterpart countries could join the Finnish quality assurance system in emission measurements if desired. (author)

    Full Text Available During heavy rains and snow melting, acid sulphate (AS soils on the coastal plains of Finland are flushed resulting in discharge of acidic and metal-rich waters that strongly affect small streams. In this study, the impact of AS soils occurrence and hydrological changes on water quality were determined for 21 rivers (catchment sizes between 96–4122 km2 running through an AS soil hotspot area in western central Finland. Water samples, collected at the outlet, during eight selected events, were analysed for pH, dissolved organic carbon, electrical conductivity (EC and 32 chemical elements. Based on the correlation with percentage arable land in the catchments (a rough estimate of AS soil occurrences, as up to 50% of the arable land is underlain with these soils, it was possible to categorize variables into those that are enriched in runoff from such land, depleted in runoff from such land (only one element, and not affected by land-use type in the catchments. Of the variables enriched in runoff from arable land, some were leached from AS soils during high-water flows, in particular (aluminium, boron, beryllium, cadmium, cobalt, copper, lithium, manganese, nickel, sulphur, silicon, thorium, thallium, uranium, and zinc and others occurred in highest concentrations during lower flows (calcium, EC, potassium, magnesium, sodium, rubidium and strontium. Molybdenum and phosphorus were not leached from AS soils in larger amounts than from other soils and thus related to other factors connected to the arable land. Based on the concentrations of potentially toxic metals derived from AS soils, the 21 rivers were ranked from the least (Lestijoki River, Lapväärtinjoki River and Perhonjoki River to the most (Sulvanjoki River, Vöyrinjoki River and Maalahdenjoki River heavily AS soil impacted. It has been decided that Vöyrinjoki is to be dredged along a ca. 20 km distance. This is quite alarming considering the high metal concentrations in the river.;

    In SW Niger, close to Niamey, a detailed hydrological survey has been developed for the last 20 years (international experiments HAPEX-SAHEL and later AMMA), investigating the distribution of water in atmosphere, surface, soil and aquifers. It covers an area of about 10 000 km2, with a series of imbricated scales of instrumentation, in time and space. This dense long term field observation led to many major scientific results. Among them, one of the most original and paradoxical is the continuous rise of the water table, even during the severe droughts of the 1970s and 1980s (about 3 m in the last 30 years). In spite of a large apparent homogeneity of the biophysical environment throughout the region, numerous heterogeneities exist at different scales, complicating the hydrological analysis. On the surface, the hydrological system was, ~6000 years ago, a structured drainage network leading to the Niger River. It was later broken into much smaller elements by aeolian dunes deposited during arid episodes and the study area now appears as a juxtaposition of hundreds of small endorheic catchments (most often 1 to 20 km2) where the surface runoff finally ends in temporary ponds. During most violent rainy events, erosion can be locally very severe and modify durably the size of the catchment and the local hydrology. Conversely, during smaller rainy events, surface runoff may never reach the ponds because it infiltrates in more permeable zones at mid-slope. The actual surface area of the catchment contributing to the surface runoff thus varies considerably with time. Because of their great number, only a few catchments are instrumented and extrapolation of measurements to ungauged catchments is an additional difficulty. Most of water temporarily stored in ponds infiltrates and recharges groundwater. The Continental Terminal (CT) aquifer system is made of three independent layers, of which the upper one (CT3) is only considered here. The CT aquifer systems is a

    Full Text Available Independent mobility in a local environment is crucial for a child’s development and physical activity, contributing to overall health and well-being. This methodological article describes a study capturing children’s daily mobility in two residential areas in Turku, southwestern Finland, by combining the methods of GPS tracking, mobility diaries, interviews and questionnaires. Geographical positioning data enables analysis of spatial characteristics of children’s mobility, e.g. the comparison to land use structure and analysis of the travel speed, while the qualitative data sets reveal how, why and with whom the travel was realised and the level of children’s independence in mobility.The results show that children’s mobility is clustered around homes and schools and evident gender differences exist; boys travel longer distances and at higher speeds than girls. The children in Turku are relatively independent and have extensive mobility licenses. However, the travel undertaken to practise hobbies or participate in organised leisure activities is realised in adult company and significantly dominated by car transportation. The results strengthen the observation that Finnish children are allowed to travel rather independently and to explore the surrounding environment without adult company, using active forms of transportation. The significant level of independence is a consequence of the high perception of safety, both from the children and the parents in the residential areas. The described mixed methods approach, combining objective measurement of actual mobility with qualitative data sets, is applicable for further mobility studies and the results offer implications for planning child-friendly urban environments.

    Geological mapping of investigation trenches OL-TK15 and OL-TK16 was carried out by the Geological Survey of Finland (GTK) at the Olkiluoto study site as a part of Posiva Oy's site investigation program for the development of an underground repository for nuclear waste. OL-TK15 is ca. N-S striking and ca. 95 m long, and OL-TK16 is ca. E-W striking and ca. 172 m long. The trenches were cleaned with pressure washer and pressurized air. The rock types were determined in field by naked eyes. Five samples from OL-TK15 and 10 samples from OL-TK16 were thin sectioned and investigated microscopically. In addition, petrophysical measurements were carried out by GTK geophysical laboratory for these samples. The bedrock within the excavation trenches OL-TK15 and OL-TK16 consists mainly of veined gneiss (VGN) with intercalations of mica gneiss (MGN), and mafic gneiss (MFGN) of amphibolite, amphibolite-gneiss, and skarn gneiss. The VGN is frankly solid or intact, fine grained and weakly banded and multiple intruded by granitic and pegmatitic veins and veinlets. Narrow scrappy zones occupied by dark dots of highly altered pseudomorphs after cordierite and/or garnet tend to be common in places. In addition, VGN contains rounded oblong mafic to intermediate fragments due to boudination of competent layers and/or dykes. Some rather narrow pegmatitic and quartz veins cut the previous tectonic structures. The prevailing tectonic structures are strong pervasive foliation and conformal veining of several generations mostly granitic in composition. The strike of the foliation and banding and veining as well, varies a little from NNE to ENE and the dip is ca. 40 - 50 degrees to SE sector, respectively. The younger folding has bent the older foliation and neosomic veining mostly with dextral monoclinic style so that in many places there occur tight kinky nodes and rootles augen like knots showing dextral rotation, too. Due to brittle deformation, there are some shear zones and zones with

    The analysis of 17 cores collected in the Odiel Estuary (SW Spain) permits delimiting the recent evolution of this zone during the past decades and the influence of natural and anthropogenic factors on the distribution of Ostracoda and Foraminifera. In the upper estuary, the coincidence of acid waters, prolonged subaerial exposure, and coarse sediments may explain the absence or the disappearance of these microorganisms during the industrial period (1966-1985) in the major part of this area. In the lower estuary, sedimentary evolution and industrial wastes are the main factors influencing both the distribution and trends of the populations of these two groups. Finally, the main changes observed in the marine estuary are due to the sedimentary effects of the construction of two banks and the dredging of the main estuarine channel. - In a polluted estuary, the meiofaunal assemblages experience different changes even in adjacent sedimentary environments, closely related to anthropogenic and natural causes

    Due to their adsorptive behavior, organotin compounds (OTCs), such as tributyltin (TBT), are accumulated in aquatic sediments. They resist biodegradation and, despite a ban in 2008, are a potential source for future exposure. Sediment OTCs have mostly been measured from sites of known high concentrations such as ports, shipping lanes, and marine dredging waste sites. The possible flow of OTCs from marine to terrestrial ecosystems, however, has not been studied. In the present study, the authors assessed whether sediments in common reed beds (Phragmites australis) accumulate TBT and whether chironomid (Diptera: Chironomidae) communities developing in reed-bed sediments act as vectors in the transfer of TBT from aquatic to terrestrial ecosystems in the Airisto channel, Archipelago Sea. The authors also investigated whether distance from the only known source and depth and TBT concentration of the adjacent shipping lane affect reed-bed concentrations. Thirty-six sites along the Airisto channel were sampled at 2-km intervals with triplicate samples from reed beds and the adjacent shipping lane for sediment and seven reed-bed sites for chironomids, and these were analyzed with an solid phase extraction liquid chromatography tamdem mass spectrometry method. The closer to the source the sample site was, the higher the measured TBT concentrations were; and the deeper the shipping lane, the lower the concentration of TBT in reed-bed sediments. The chironomid TBT concentrations correlated with reed-bed sediment TBT concentrations and showed evidence of accumulation. Therefore, TBT may be transferred, through the food web, from aquatic to terrestrial ecosystems relatively close to a source through ecosystem boundaries, such as common reed beds, which are areas of high insect biomass production in the Archipelago Sea.

    Fluorine (F) is a topic of great interest in coal-combustion related endemic fluorosis areas. However, little extent research exists regarding the environmental geochemistry of toxic elements that are enriched in coals and coal wastes in traditional endemic fluorosis areas, particularly focusing on their occurrences and mobilities during the weathering-leaching processes of coals and coal wastes in the surface environment. This paper addressed the issue of toxic elements in coals and coal wastes in the Three Gorges Region, Southwest (SW) China, where endemic fluorosis has historically prevailed, and investigated the distribution, occurrence, mobility features, and associated potential health risks. For this purpose, a modified experiment combined with long-term humidity cell test and column leaching trial was applied to elucidate the mobility of toxic elements in coals and coal wastes. In addition, sequential chemical extraction (SCE) was used to ascertain the modes of occurrence of toxic elements. The results demonstrated that the contents of toxic elements in the study area followed the order: stone coals > gangues > coal balls > coals. Furthermore, modes of occurrence of toxic elements were obviously different in coals and coal wastes. For example, cadmium (Cd) was mainly associated with monosulfide fraction in coals, molybdenum (Mo) and arsenic (As) were mainly associated with carbonate and silicate in coal gangues and stone coals, chromium (Cr) mainly existed in silicate and insoluble matter in coal gangues and coal balls, thallium (Tl) mainly occurred in organic matter in stone coals and sulfide in coals, and the occurrence of antimony (Sb) varied with different kinds of samples. Moreover, a large amount of toxic elements released to the leachates during the weathering and leaching process, which might pollute the environment and threaten human health.

    Full Text Available The Kuh Shah prospecting area is located in Tertiary volcano-plutonic belt of the Lut Block. More than seventeen subvolcanic intermediate to acidic intrusive rocks, diorite to syenite in composition, were identified in the study area. The intrusions are related to hydrothermal alteration zones and contain argillic, propylitic, advanced argillic, silicified, quartz-sericite-pyrite, gossan and hydrothermal breccia which overprinted to each other and are accompanied by weathering which made it complicated to distinguish zoning. Mineralization is observed as sulfide (pyrite and rare chalcopyrite, disseminated Fe-oxides and quartz-Fe-oxide stockwork veinlets. Intrusive rocks are metaluminous, calc-alkaline with shoshonitic affinity with high values of magnetic susceptibility. The Kuh Shah intrusive rocks are classified as magnetite-series of oxidant I-type granitoids. Based on zircon U–Pb age dating, the age of these granitoid rocks is 39.7± 0.7 Ma (Middle Eocene. The radioisotope data (initial 87Sr/86Sr and 143Nd/144Nd ratios as well as εNd and geochemical data suggest that the Kuh Shah granitoid rocks formed from depleted mantle in a subduction-related magmatic arc setting. Geochemical anomalies of elements such as Cu, Au, Fe, Pb, Zn, As, Sb, Mo, Bi, Hg and also Mn, Ba, Te and Se, correlated with quartz-sericite-pyrite, gossan-stockwork-hydrothermal breccias, irregular silicified bodies and advanced argillic hydrothermal alteration zones. Geophysical anomalies correlated with hydrothermal alteration and mineralization zones. The interpretation of the results represents complex patterns of sub-circular to ellipsoid shape with north-east to south-west direction. These evidences are similar to the other for known Cu-Au porphyry and Au-epithermal systems in Iran and worldwide.

    A series of meetings between the Central Kola Survey Expedition, Geological Survey of Finland and Geological Survey of Norway in 1991-1992 led to the implementation of a pilot project of a joint ecogeochemical study of the impacts of industrial activities on the terrestrial systems of West Kola Peninsula and adjacent areas in Finland and Norway. The main aims of this pilot project were to harmonize methods of sampling, preparation, analysis, data treatment and interpretation, focusing on heavy metals and radionuclides. A small area in the three-country field, including Nikel, Zapoljarny and Kirkenes was chosen as test territory. Experiences of the pilot project should form a base for planning a major project to cover some 170000 km 2 in the three countries. Snow cover, terrestrial moss, A 0 -horizon, A 0+2 -horizon, C-horizon, stream water, stream sediments and overbank sediments were used as sampling medias, with 15 sites in each country. A data quality assessment was carried out, and maps of pollutant elements clearly delineate patterns similar to those found by other workers. There is no indication that C-horizon is affected, but results of overbank sediments indicate that there are abnormal conditions with regards to the sediment transport and chemistry in the ''industrial desert''. Results of 134,137 Cs determinations in the uppermost 5 cm of the soil profile show no alarming levels. An attempt at modelling the flux of contaminants has also been made. 29 refs., 54 figs., 9 tabs

    Full Text Available The characterization, evaluation and remediation of polluted soils is one of the present environmental challenges to be addressed in the coming years. The origin of trace elements in soils can be either geogenic or anthropogenic, but only the latter is interesting from a legal point of view. The hazard of the pollutants in the soils not only depends on their total concentration, but particularly on their availability. The mobility of the trace elements depends on their speciation, and it is also affected by several soil parameters. Mining activity is one of the most important anthropogenic causes of soil pollution. As a case study, this work is focused in the Riotinto mining area (Iberian Pyrite Belt, IPB, SW Spain. The IPB is one of the most important metallogenic provinces in the world and it has been exploited for thousands of years. The disposal of mining residues has produced important sources of contamination by trace elements and acidic waters affecting soils and rivers. In addition to these problems, the closure of mines in the Pyrite Belt at the end of the 20th Century has led to a great loss of employment, which has caused the development of an intensive agriculture of citrus fruits as a new source of income. The intensive growing of citrus fruits and the traditional subsistence agriculture have been developed surrounding the mining areas and on floodplains near to mining sites. The level of soil pollution has not been taken into account in these cases, nor has its impact on the health of the inhabitants of these areas. Therefore, it is of great interest to study the current state of the cultivated soils and the sources and types of contaminants derived from mining activity in order to program its decontamination, where appropriate, according to legislation. In order to know the present and future hazard posed by the soils chemical and mineralogical speciation has been carried out, given that the availability of a metal depends on the

    Southeastern Finland belongs to the area covered by the Weichselian ice sheet, where the release of the ice load caused a rapid isostatic rebound during the postglacial time. While the mean overall apparent uplift is of the order of 2 mm/yr today, in the early Holocene time it was several times higher. A marked decrease in the rebound rate occurred around 8500 BP, however, since then the uplift rate has remained high until today, with a slightly decreasing trend towards the present time. According to current understanding there have neither been temporary increases nor decreases in the rate of uplift during the postglacial time. Even so, it is not known for sure whether there are regional irregularities on the rebound in Finland. Concurrently with land uplift, relative sea-level changes in the Baltic basin were also strongly affected by the global eustatic rise of sea-level. During the early Litorina Sea stage on the southern coast of Finland around 7000 BP, the rise in sea-level exceeded the rate of land uplift, and resulted in a short-lived transgression. The most accurate information on relative sea-level changes in an uplifting area may be obtained from radiocarbon dated events of isolation in small lake basins, as they were cut off from larger bodies of water. The isolations of such basins from the sea may be reliably determined by the recorded changes in the diatom flora in the sediment sequences, at horizons which may be radiometrically dated. In the present study, the isolation-horizons of 13 basins were dated by 26 conventional and 2 AMS radiocarbon dates. According to the available sets of dates, the time span of emergence extends from 8300 BP to the past few hundred years, for lakes from c. 30 m to 1.1 m above the present sea-level. Due to the global rise in sea-level, during the period of 7500-6500 BP, the sea-level rise clearly exceeded the rate of uplift, and resulted in the Litorina transgression, which had an amplitude of around one metre.

    Trace elements may present an environmental hazard in the vicinity of mining and smelting activities. However, the factors controlling trace element distribution in soils around ancient and modern mining and smelting areas are not always clear. Tharsis, Riotinto and Huelva are located in the Iberian Pyrite Belt in SW Spain. Tharsis and Riotinto mines have been exploited since 2500 B.C., with intensive smelting taking place. Huelva, established in 1970 and using the Flash Furnace Outokumpu process, is currently one of the largest smelter in the world. Pyrite and chalcopyrite ore have been intensively smelted for Cu. However, unusually for smelters and mines of a similar size, the elevated trace element concentrations in soils were found to be restricted to the immediate vicinity of the mines and smelters, being found up to a maximum of 2 km from the mines and smelters at Tharsis, Riotinto and Huelva. Trace element partitioning (over 2/3 of trace elements found in the residual immobile fraction of soils at Tharsis) and soil particles examination by SEM-EDX showed that trace elements were not adsorbed onto soil particles, but were included within the matrix of large trace element-rich Fe silicate slag particles (i.e. 1 mm o at least 1 wt.% As, Cu and Zn, and 2 wt.% Pb). Slag particle large size (1 mm o) was found to control the geographically restricted trace element distribution in soils at Tharsis, Riotinto and Huelva, since large heavy particles could not have been transported long distances. Distribution and partitioning indicated that impacts to the environment as a result of mining and smelting should remain minimal in the region.

  10. The composition of the ground water in bedrock in the precambrian shield areas of Finland and other countries

    1986-11-01

    The main properties of the composition of the ground water contained in the Precambrian bedrock of Finland are presented on the basis of the results of analyses of some 1750 water samples taken from bored wells and a few mines. They show that, with a few exceptions, the waters of bored wells are bicarbonate waters, in which the average total amount of dissolved substances diminishes according to their geographical location as one moves from the coastal areas toward estern and northern Finland. The influence of the mineral composition of the bedrock appears most distinctly in the rapakivi areas, where the average fluoride content of the ground water varies between 1.5 and 2.0 mg/l and is thus ten times the corresponding content prevailing in areas characterized by other types of rocks. Ground waters containing from 439 to 18.000 mg/l of chloride have also been met with in Finnish bedrock and the location of the sampling site of 38 samples is given together with the general nature of their chemical composition as well as the results of the determinations of the stable (δ ''2H, δ ''1''8O, δ ''3''4S, δ ''1''3C) and radioactive (''3H, ''1''4C) isotopes of a number of samples. The saline waters are mostly located in the region covered 6000-7500 years ago by the Littorina Sea. On the other hand, the isotopic composition of many saline waters corresponds to that of rainwater fallen during climatic conditions colder than the present. The most saline waters have been met with deep down in mines and deep boreholes, also, for example, far from the region covered by the Littorina Sea. The saline waters contained in Finnish bedrock usually release gas, which in some cases consists mainly of nitrogen but in some places includes significant amounts of methane. In addition, helium is one of the constituents

    In Finland, hospital districts (HD) are required by law to determine the level and availability of Emergency Medical Services (EMS) for each 1-km 2 sized area (cell) within their administrative area. The cells are currently categorised into five risk categories based on the predicted number of missions. Methodological defects and insufficient instructions have led to incomparability between EMS services. The aim of this study was to describe a new, nationwide method for categorising the cells, analyse EMS response time data and describe possible differences in mission profiles between the new risk category areas. National databases of EMS missions, population and buildings were combined with an existing nationwide 1-km 2 hexagon-shaped cell grid. The cells were categorised into four groups, based on the Finnish Environment Institute's (FEI) national definition of urban and rural areas, population and historical EMS mission density within each cell. The EMS mission profiles of the cell categories were compared using risk ratios with confidence intervals in 12 mission groups. In total, 87.3% of the population lives and 87.5% of missions took place in core or other urban areas, which covered only 4.7% of the HDs' surface area. Trauma mission incidence per 1000 inhabitants was higher in core urban areas (42.2) than in other urban (24.2) or dispersed settlement areas (24.6). The results were similar for non-trauma missions (134.8, 93.2 and 92.2, respectively). Each cell category had a characteristic mission profile. High-energy trauma missions and cardiac problems were more common in rural and uninhabited cells, while violence, intoxication and non-specific problems dominated in urban areas. The proposed area categories and grid-based data collection appear to be a useful method for evaluating EMS demand and availability in different parts of the country for statistical purposes. Due to a similar rural/urban area definition, the method might also be usable for

    2018-01-01

    An International Atomic Energy Agency (IAEA) team of experts said the operator of Finland’s Loviisa Nuclear Power Plant (NPP) demonstrated a commitment to safety. The team also identified areas for further enhancement. The Operational Safety Review Team (OSART) concluded an 18-day mission on 22 March to Loviisa NPP, whose two 531-MWe pressurized-water reactors started commercial operation in 1977 and 1980, respectively. Fortum Power and Heat OY operate the plant, located about 100 km east of Helsinki, the capital. Nuclear power generates one-third of electricity in Finland, which has four operating power reactors and is constructing a fifth reactor. OSART missions aim to improve operational safety by objectively assessing safety performance using the IAEA’s safety standards and proposing improvement where appropriate. The 16-member team comprised experts from Brazil, Canada, China, France, Germany, Hungary, Romania, Russia Federation, Slovak Republic, South Africa, Spain, Ukraine, United Kingdom, United States of America as well as IAEA officials. The review covered the areas of leadership and management for safety; training and qualification; operations; maintenance; technical support; operating experience; radiation protection; chemistry; emergency preparedness and response; accident management; human, technology and organizational interactions; and long-term operation. The team identified a number of good practices that will be shared with the nuclear industry globally, including: • The plant has developed the capability to automatically calculate leak rate tests of containment. • The plant established a process to test and improve modifications and updates early. • The plant has adopted a key system to effectively control access to various rooms in the plant. The mission made several proposals to improve operational safety, including: • The plant management should improve communications of their expectations and consistently reinforce their

    The possibility of current-driven propagation of contaminants released along a major fairway polluting the Marine Protected Areas (MPAs) in the Gulf of Finland, the Baltic Sea, is examined using a 3D circulation model, a Lagrangian transport model and statistics. Not surprisingly, the number of hits to the MPA decreases almost linearly with its distance from the fairway. In addition, the potential pollution released during a ship accident with the pollutants carried by currents may affect MPAs at very large distances. Typically, a fairway section approximately 125 km long (covering about 1/3 of the approximate 400-km-long gulf) may serve as a source of pollution for each MPA. The largest MPA (in the Eastern Gulf of Finland) may receive pollution from an approximately 210-km-long section (covering about 1/2 of the entire length of the gulf). This information may be useful in assisting maritime management. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Homelessness is associated with increased morbidity, mortality and health care use. The aim of this study was to examine the role of mental disorders in relation to the use of 1) daytime primary health care services and 2) after hours primary health care emergency room (PHER) services among homeless shelter users in the Helsinki Metropolitan Area, Finland. The study cohort consists of all 158 homeless persons using the four shelters operating in the study area during two selected nights. The health records were analyzed over a period of 3 years prior to the sample nights and data on morbidity and primary health care visits were gathered. We used negative binomial regression to estimate the association between mental disorders and daytime visits to primary health care and after hours visits to PHERs. During the 3 years the 158 homeless persons in the cohort made 1410 visits to a physician in primary health care. The cohort exhibited high rates of mental disorders, including substance use disorders (SUDs); i.e. 141 persons (89%) had a mental disorder. We found dual diagnosis, defined as SUD concurring with other mental disorder, to be strongly associated with daytime primary health care utilization (IRR 11.0, 95% CI 5.9-20.6) when compared with those without any mental disorder diagnosis. The association was somewhat weaker for those with only SUDs (IRR 4.9, 95% CI 2.5-9.9) or with only other mental disorders (IRR 5.0, 95% CI 2.4-10.8). When focusing upon the after hours visits to PHERs we observed that both dual diagnosis (IRR 14.1, 95% CI 6.3-31.2) and SUDs (11.5, 95% CI 5.7-23.3) were strongly associated with utilization of PHERs compared to those without any mental disorder. In spite of a high numbers of visits, we found undertreatment of chronic conditions such as hypertension and diabetes. Dual diagnosis is particularly strongly associated with primary health care daytime visits among homeless persons staying in shelters, while after hours visits to primary

    Samples of summer pasture plants that reindeer feed on were collected in order to study {sup 137}Cs concentrations in different plant species and in species nested in certain site types, and to study the regional distribution of {sup 137}Cs in the Finnish reindeer management area. Plant species were categorized by the site types of mineral soil forest (xeric heath forest and mesic heath forest) and peatland. A third category called 'other plant species' included plants with various site types, poorly determined species and species with poor statistics. The {sup 137}Cs concentrations in different site types differed significantly. The mean {sup 137}Cs concentrations of the whole reindeer management area in the xeric heath forest plant species was 44 {+-} 27 Bq/kg dw, in the mesic heath forest plant species 75 {+-} 59 Bq/kg dw and in the peatland plant species 219 {+-} 150 Bq/kg dw. The peatland species uptake {sup 137}Cs more efficiently than plant species of mineral soil forests. A particularly efficient collector of {sup 137}Cs was Trichophorum sp. It is suggested that Trichophorum sp. could be used as an indicator species for reindeer summer fodder plants. The highest concentrations of {sup 137}Cs were found in Southern Lapland and the lowest in Northern Lapland. Today, the concentrations of {sup 137}Cs in summer pasture plants that reindeer feed on in Finland are at such a level that there is no need to avoid any plant species. In the case of future nuclear fallout, reindeer grazing in peatlands would increase concentrations of {sup 137}Cs in reindeer meat. - Highlights: > The {sup 137}Cs concentrations were found to be higher in the plants of peatlands. > There was also a decreasing trend {sup 137}Cs concentrations in the plants of peatlands when moving northwards while xeric heath and mesic heath forest did not show clear spatial pattern. > No significant difference was found between plants species from xeric and mesic heath forest plants. > The

    This is a report of a country case study on the impacts of climate change and local people's adaptation. The research sites are located in the karst mountainous region in 3 SW China provinces - Guangxi, Guizhou and Yunnan – an area inhabited by 33 ethnic groups of small farmers and the poor, with rich Plant Genetic Resources (PGR) and culture. Climate change is exacerbating already harsh natural conditions and impacting on biodiversity of remote farmers living in extreme poverty, with very limited arable land. Genetic diversity has also suffered from the adoption of high yielding hybrids. Yet traditional varieties, related TK and Participatory Plant Breeding (PPB) for maize and rice are showing real potential for resilience and adaptation.

    Full Text Available EU has set sustainable growth as a goal for 2020, by which a transition to a more resource efficient greener and competitive economy should be achieved. This requires new skills in business life. We have studied how vocational education and training and higher education may serve as a promoter of a green and low-carbon economy in Finland. Based on results from interviews of companies three main areas were chosen. These areas were decentralized renewable energy production, use of organic by-products and promotion of energy efficiency in properties. Education in vocational education and training and universities of applied sciences, for the selected areas, was mapped in 2014-15. The results were presented on workshops, where knowledge supply chains for a green economy on the selected areas were developed. If was found that cooperation between different fields and levels of education is important, as the new skills often emerge at the interfaces.

    Full Text Available In the terms of current climate change, reconversion of land use in the drought-and aridityaffected south-western Romania, is an issue of utmost priority. Thus, the present study aim represents a diachronic analysis of the land use within the Bechet town area and proposes viable solutions for soil drought and aridity mitigation. Since 1989, uncontrolled and abusive logging affected the black locust forest areas, enabling the sand dunes expansion and causing ecological disturbance. The main research methods were: field observation, statistical-mathematical methods and GIS mapping. The analysis of topographic maps and orthophotographs in 1970 to 2008 revealed a very low spatial distribution of both the forest shelterbelts and shelterwoods. We proposed a reconstruction of these forest areas, which today can no longer perform their fundamental function of land protection, because of intensive degradation. The positive consequences on long term would be the mitigation of climate change impact and prevention of further land degradation.

    Full Text Available In this research article the sustainability of different practices to collect the metal fraction of household waste in the Helsinki metropolitan area, Finland is examined. The study is carried out by calculating and comparing the greenhouse gas reduction potential of optional practices for collecting the metal fraction of household waste in the Helsinki metropolitan area, Finland. In order to locate the greenhouse gas reduction potential of the separate collection of the metallic fraction of municipal solid waste (MSW collected from residential sources, a comparative carbon footprint analysis using Life Cycle Assessment (LCA on six different waste management scenarios is carried out. The modeled system consisted of a waste collection system, transportation, and different waste management alternatives, including on-site separation, separation at the waste management facility as well as metallurgical recovery of separated scrap. The results show that, in terms of greenhouse gas emissions, separate collection and recycling of the metallic fraction of solid MSW at residential properties is the preferable option compared to a scenario with no source sorting and incineration of everything. According to this research scenario where the metal fraction of solid household waste was not source-separated or collected separately have clearly higher greenhouse gas emissions compared to all the other scenarios with separate collection for metals. In addition, metal recycling by regional collection points has considerably lower greenhouse gas emission potential than metal recycling by collection directly from residential properties.

    The sewage pollution impact over coastal environment represents one of the main reasons explaining the deterioration of marine coastal ecosystems around the globe. This paper aims to detect promptly a putative sewage pollution impact in a Southwestern Atlantic coastal area of Argentina as well as to identify a straightforward way for monitoring, based on the relative abundance coverage of the intertidal epilithic taxa. Four sampling sites were distributed at increased distances from the sewage outfall where the cover of individual epilithic species was visually estimated. The surrounded outfall area (i.e. outfall site) resulted polluted with high percentages of organic matter in sediment and Enterococcus concentration in seawater. The structure of the community showed a remarkable difference between the polluted site (outfall site) and the unpolluted sites. The polychaete Boccardia proboscidea dominated the outfall site with variable abundances of the green algae Ulva sp. during the period of study, decreasing the diversity of the community, while the mussel Brachidontes rodriguezii and variable abundances of several algae species dominated the unpolluted sites. The monitoring of the benthic community represents an effective, non-destructive, relative inexpensive and rapid method to assess the health of the coastal environment in the study area.

    The study of quick clay landslides in Nordic countries, such as Sweden and Norway, is wide and varied. However, the occurrence of catastrophes like those in Munkedal, Sweden, in 2006, demands a more complete characterization of these materials and their extensiveness. The objectives of this research are mainly focused on obtaining information about the properties and behavior of quick clays in an area prone to landslides in southwestern Sweden. Two fieldwork campaigns were carried out in 2011 and 2013, using methods such as 2D and 3D P-wave and S-wave seismic, geoelectrics, controlled-source and radio-magnetotellurics, ground gravity, as well as downhole geophysics (measuring fluid temperature and conductivity, gamma radiation, sonic velocity and resistivity) performed in three boreholes located in the study area. Drill cores recovered using the SONIC technique provided samples for paleontological information, as well as laboratory measurements of physical properties of the subsurface materials to a maximum subsurface depth of about 60 m. The laboratory measurements included grain size analysis, mineral magnetic properties, electric conductivity, pH, salinity, total dissolved solids, x-ray fluorescence (XRF), and a reconnaissance study of the fossil content. A correlation study of the downhole geophysical measurements, 2D seismic sections located at the intersection with the boreholes and the sample observations indicated that the presence of quick clays is associated with contacts with coarse-grained materials. Although the PVC casing of the boreholes interferes with the sonic and resistivity measurements, the perforated parts of the PVC casing show significant changes. The most important variations in magnetic susceptibility and conductivity mostly coincide with these coarse-grained layers, supporting the seismic data. Coarse-grained layers are characterized by enhanced magnetic susceptibility and conductivity. Grain size analysis results on subsamples from the

    Tissue N contents and δ 15 N signatures in 175 epilithic mosses were investigated from urban to rural sites in Guiyang (SW China) to determine atmospheric N deposition. Moss N contents (0.85-2.97%) showed a significant decrease from the urban area (mean = 2.24 ± 0.32%, 0-5 km) to the rural area (mean = 1.27 ± 0.13%, 20-25 km), indicating that the level of N deposition decreased away from the urban environment, while slightly higher N contents re-occurred at sites beyond 30 km, suggesting higher N deposition in more remote rural areas. Moss δ 15 N ranged from -12.50 per mille to -1.39 per mille and showed a clear bimodal distribution (-12 per mille to -6 per mille and -5 per mille to -2 per mille ), suggesting that there are two main sources for N deposition in the Guiyang area. More negative δ 15 N (mean = -8.87 ± 1.65 per mille ) of urban mosses mainly indicated NH 3 released from excretory wastes and sewage, while the less negative δ 15 N (from -3.83 ± 0.82 per mille to -2.48 ± 0.95 per mille ) of rural mosses were mainly influenced by agricultural NH 3 . With more negative values in the urban area than in the rural area, the pattern of moss δ 15 N variation in Guiyang was found to be opposite to cities where N deposition is dominated by NO x -N. Therefore, NH x -N is the dominant N form deposited in the Guiyang area, which is supported by higher NH x -N than NO x -N in local atmospheric deposition. From the data showing that moss is responding to NH x -N/NO x -N in deposition it can be further demonstrated that the variation of moss δ 15 N from the Guiyang urban to rural area was more likely controlled by the ratio of urban-NH x /agriculture-NH x than the ratio of NH x -N/NO x -N. The results of this study have extended knowledge of atmospheric N sources in city areas, showing that urban sewage discharge could be important in cities co-generic to Guiyang

    An extensive study of the resistivity structure of the Hengill area in SW Iceland was carried out by the combined use of TEM and MT soundings. Joint inversion of the collected data can correct for static shifts in the MT data, which can be severe due to large near-surface resistivity contrasts. Joint 1D inversion of 148 TEM/MT sounding pairs and a 3D inversion of a 60 sounding subset of the MT data were performed. The 3D inversion was based on full MT impedance tensors previously corrected for static shift. Both inversion approaches gave qualitatively similar results, and revealed a shallow resistivity layer reflecting conductive alteration minerals at temperatures of 100-240 C. They also delineated a deep conductor at 3-10 km depth. The reason for this deep-seated high conductivity is not fully understood. The distribution of the deep conductors correlates with a positive residual Bouguer gravity anomaly, and with transform tectonics inferred from seismicity. One model of the Hengill that is consistent with the well temperature data and the deep conductor that does not attenuate S-waves, is a group of hot, solidified, but still ductile magmatic intrusions that are closely associated with the heat source for the geothermal system.

    The Odiel watershed drains materials belonging to the Iberian Pyrite Belt, where significant massive sulfide deposits have been mined historically. As a result, a huge amount of sulfide-rich wastes are deposited in the watershed, which suffer from oxidation, releasing acidic lixiviates with high sulfate and metal concentrations. In order to reliably estimate the metal loadings along the watershed a complete series of discharge and hydrochemical data are essential. A hydrological model was performed with SWAT (Soil and Water Assessment Tool) to solve the scarcity of gauge stations along the watershed. The model was calibrated and validated from daily discharge data (from 1980 to 2010) at the outlet of the watershed, river inputs into an existent reservoir, and a flow gauge station close to the northern area of the watershed. Discharge data obtained from the hydrological model, together with analytical data, allowed the estimation of the dissolved pollutant load delivered annually by the Odiel River (e.g. 9140 t of Al, 2760 t of Zn). The pollutant load is influenced strongly by the rainfall regime, and can even double during extremely rainy years. Around 50% of total pollution comes from the Riotinto Mining District, so the treatment of Riotinto lixiviates reaching the Odiel watershed would reduce the AMD (Acid Mine Drainages) in a remarkable way, improving the water quality downstream, especially in the reservoir of Alcolea, currently under construction. The information obtained in this study will allow the optimization of remediation efforts in the watershed, in order to improve its water quality.

    The purpose of this study was to explore nurse managers' perceptions related to their leadership styles, knowledge, and their skills in these areas in health centre wards in Finland. The data were collected from nurse managers (n = 252) in health centre hospitals in Finland using a structured questionnaire (response rate 63%). Six leadership styles-visionary, coaching, affiliate, democratic, commanding, and isolating-were reflected on. Almost all respondents in every age group considered four leadership styles-visionary, coaching, affiliate, and democratic-to be very important or important. Nurse managers estimated their knowledge and skills in leadership styles to be essentially fairly sufficient or sufficient. Nurse managers' abilities to reflect, understand, and, if necessary, change their leadership style influence the work unit's success and employees' job satisfaction. Nurse managers, especially new nurse managers, need more theoretic, evidence-based education to cope with these expectations and to develop their professional abilities. Together with universities, health care organizations should start planning nurse manager education programmes that focus on strategic issues, leadership, job satisfaction, challenging situations in leadership, change management, work unit management (e.g., economy, efficiency, and resources), and how the nurse managers consider their own wellbeing.

    Marine protected areas (MPAs) are a relatively recent fisheries management and conservation tool for conservation of marine ecosystems and serve as experimental grounds to assess trophic cascade effects in areas were fishing is restricted to some extent. A series of descriptive field studies were performed to assess fish and benthic communities between two areas within a newly established MPA in SW Portugal. We characterized benthic macroalgal composition and determined the size, density and biomass of the main benthic predatory and herbivorous fish species as well as the main benthic herbivorous invertebrates to assess indications of top-down control on the phytobenthic assemblages. Fish species were identical inside and outside the MPA, in both cases Sarpa salpa was the most abundant fish herbivore and Diplodus spp. accounted for the great majority of the benthic predators. However, size and biomass of D. spp. were higher inside than outside the MPA. The main herbivorous invertebrate was the sea urchin Paracentrotus lividus, which was smaller and predominantly showing a crevice-dwelling behaviour in the MPA. In addition, P. lividus size frequency distribution showed a unimodal pattern outside and a bimodal pattern inside the MPA. We found significant differences in the algal assemblages between inside and outside the MPA, with higher abundance of turf and foliose algae inside, and articulated calcareous and corticated macrophytes outside the MPA, but no differences in the invasive Asparagopsis spp. The obtained results show differences in predatory fish and benthic community structure, but not in species richness, inside and outside the MPA. We hypothesize these differences lead to variation in species interactions: directly through predation and indirectly via affecting sea urchins behavioural patterns, predators might drive changes in macroalgal assemblages via trophic cascade in the study area. However due to non-biological differences between the two areas it

    Seismic reflection surveys in boreholes were carried out for Teollisuuden Voima Oy at five sites in Finland (Eurajoki Olkiluoto, Hyrynsalmi Veitsivaara, Konginkangas Kivetty, Kuhmo Romuvaara and Sievi Syyry). The vertical Seismic Profiling (VSP) surveys were a part of the investigation programme for the final disposal of spent nuclear fuel. The purpose was to detect fractured zones, lithological contacts and other anomalies in the structure of the rockmass and to determine their position and orientation. Horizontal Seismic Profiling (HSP) was used at the Olkiluoto site, additionally to VSP. The data has been organized in profiles containing seismograms recorded from the same shotpoint (shot gathers). One of the most powerful processing methods used with this project has been the Image Space Filtering, a new technique, which has been developed (in the project) for seismic reflection studies in crystalline rock. The method can be applied with other rock types where steeply inclined or vertical anomalies are of interest. It acts like a multichannel filter, enhancing the reflected events and also as an interpretation tool, to estimate the strength and position of the reflectors. This approach has been of great help in emphasizing the weak reflections from uneven and sometimes vanishing interfaces encountered in crystalline

    To examine the scope of strategic wellness management (SWM) in Finland. To measure management of wellness a strategic wellness management index (SWMI) was developed. On the basis of the developed SWM model an Internet questionnaire was conducted for randomly selected employers representing seven business areas and three size categories. Corporate activities and SWMI for each employer and for business area and size groups were calculated. Results highlighted relatively good activity in strategic wellness (SW) processes and fairly low level of SWM procedures. The average values (± SD) of SWMI were 53.6 ± 12.3 for large, 42.8 ± 11.7 for medium-size, and 32.8 ± 12.1 for small companies. SWMI can be a positive new, strong concept to measure SW processes and thus improve both the well-being of the employees and the productivity of the enterprise.

The latter is achieved by a combined use of Soil and Water Assessment Tool (SWAT) modeling with our own purpose-built land use generator module (Generator of Land Use version 2 (GenLU2)) and an economic model developed using General Algebraic Modeling System (GAMS) for cost-effectiveness assessment. This integrated approach is applied to two embedded catchment areas (total area of 360,000 ha) within the Charente river basin (SW France). Our results show that it is possible to differentiate scenarios based on their effectiveness, represented by either evolution of pressure (agro-environmental indicators) or transport into waters (pesticide concentrations). By analyzing the implementation costs borne by farmers, it is possible to identify the most cost-effective scenarios at sub-basin and other aggregated levels (WFD hydrological entities, sensitive areas). Relevant results and indicators are fed into a specifically designed database. Data warehousing is used to provide analyses and outputs at all thematic, temporal, or spatial aggregated levels, defined by the stakeholders (type of crops, herbicides, WFD areas, years), using Spatial On-Line Analytical Processing (SOLAP) tools. The aim of this approach is to allow public policy makers to make more informed and reasoned decisions when managing sensitive areas and/or implementing mitigation measures.

    This paper presents selected results of research connected with the development of a (3D) geostatistical hydrogeochemical model of the Klodzko Drainage Basin, dedicated to the spatial and time variation in the selected quality parameters of underground water in the Klodzko water intake area (SW part of Poland). The research covers the period 2011÷2012. Spatial analyses of the variation in various quality parameters, i.e, contents of: ammonium ion [gNH4+/m3], NO3- (nitrate ion) [gNO3/m3], PO4-3 (phosphate ion) [gPO4-3/m3], total organic carbon C (TOC) [gC/m3], pH redox potential and temperature C [degrees], were carried out on the basis of the chemical determinations of the quality parameters of underground water samples taken from the wells in the water intake area. Spatial and time variation in the quality parameters was analyzed on the basis of archival data (period 1977÷1999) for 22 (pump and siphon) wells with a depth ranging from 9.5 to 38.0 m b.g.l., later data obtained (November 2011) from tests of water taken from 14 existing wells. The wells were built in the years 1954÷1998. The water abstraction depth (difference between the terrain elevation and the dynamic water table level) is ranged from 276÷286 m a.s.l., with an average of 282.05 m a.s.l. Dynamic water table level is contained between 6.22 m÷16.44 m b.g.l., with a mean value of 9.64 m b.g.l. The latest data (January 2012) acquired from 3 new piezometers, with a depth of 9÷10m, which were made in other locations in the relevant area. Thematic databases, containing original data on coordinates X, Y (latitude, longitude) and Z (terrain elevation and time - years) and on regionalized variables, i.e. the underground water quality parameters in the Klodzko water intake area determined for different analytical configurations (22 wells, 14 wells, 14 wells + 3 piezometers), were created. Both archival data (acquired in the years 1977÷1999) and the latest data (collected in 2011÷2012) were analyzed

    The increase in concentration of greenhouse gases (CO{sub 2}, CH{sub 4} and N{sub 2}O) in atmosphere is associated with burning of fossil fuels and also changes in biogeochemistry due to land use activities. Virgin peatlands are globally important stores of carbon and sources of CH4. Peatland drainage changes the processes in carbon and nitrogen cycles responsible for the fluxes of CO{sub 2}, CH{sub 4} and N{sub 2}O. Preparing of peatlands for peat mining greatly change their biogeochemical processes. Effective drainage decreases water table and allows air to penetrate deep into peat profile. Aerobic conditions inhibit activities of anaerobic microbes, including the methanogens, whereas aerobic processes like methane oxidation are stimulated. Destruction of vegetation cover stops the carbon input to peat. In Finland the actual peat mining area is 0.05 x 106 hectares and further 0.03 x 106 hectares have been prepared or are under preparation for peat mining. The current total peatland area in the world used for mining is 0.94 x 106 ha and the area already mined is 1.15 x 106 ha. In this presentation fluxes of greenhouse gases (CH{sub 4}, CO{sub 2} and N{sub 2}O) on some mires under peat mining are reported and compared with those on natural mires and with the emissions from peat combustion.

    The results of the marine radioecology studies carried out in 2000-2001 in the sea areas off the Loviisa and Olkiluoto Nuclear Power Plants (South and West coast of Finland) are reported. Extensive regular monitoring programmes of environmental radioactivity have been carried out already for about 30 years in these areas. The aim of the present study was to compare the indicator value of the various members of the aquatic ecosystem with respect to environmental monitoring. Samples were taken from 27 species including phytoplankton (9 samples), zooplankton (9 samples), periphyton (12 samples), macroalgae and vascular plants (16 samples), benthic animals (8 samples), fish (20 samples) and birds (6). Special attention was paid to different tissues and organs of fish and birds, such as flesh, liver, entrails, bones, milt, spawn, eggs, egg shells etc. (in total 64 samples), because there has been a lot of debate among the opponents of nuclear power in the course of time about the role these objects in the environmental monitoring of the power plants. The samples were taken from relatively small areas both in Loviisa and Olkiluoto, which makes the results well comparable inside each of the sites. (au)

    Calcareous shales and black limestones of the Jurassic Amran Group, located in the Sharab area (SW Yemen), were analysed based on organic and inorganic geochemical methods. The results of this study were used to reconstruct the paleoenvironmental and paleoclimatic conditions during Jurassic time and their relevance to organic matter enrichment during deposition of the Amran calcareous shale and black limestone deposits. The analysed Amran samples have present-day TOC and Stotal content values in the range of 0.25-0.91 wt % and 0.59-4.96 wt %, respectively. The relationship between Stotal and TOC contents indicates that the Jurassic Amran deposits were deposited in a marine environment as supported by biomarker environmental indicators. Biomarker distributions also reflect that the analysed Amran deposits received high contributions of marine organic matter (e.g., algal and microbial) with minor amount of land plant source inputs. Low oxygen (reducing) conditions during deposition of the Jurassic Amran deposits are indicated from low Pr/Ph values and relatively high elemental ratios of V/Ni and V/(V + Ni). Enrichment in the pyrite grains and very high DOPT and high Fe/Al ratios further suggest reducing bottom waters. This paleo-redox (i.e., reducing) conditions contributed to preservation of organic matter during deposition of the Jurassic Amran deposits. Semi-arid to warm climatic conditions are also evidenced during deposition of the Amran sediments and consequently increased biological productivity within the photic zone of the water column during deposition. Therefore, the increased bio-productivity in combination with good preservation of organic matter identified as the major mechanisms that gave rise to organic matter enrichment. This contradicts with the low organic matter content of the present-day TOC values of less than 1%. The biomarker maturity data indicate that the analysed Amran samples are of high thermal maturity; therefore, the low present-day TOC

    The energy sector in Finland is heavily constrained by the tough northern climate, meagre fuel reserves, an expensive infrastructure, the small domestic market and limited capital resources. However, Finland`s forest and metal industries have demanded low-cost energy, considering it vital for their existence and therefore for the prosperity of the whole country. Finland`s extensive foreign trade and open policies have also furthered this process; they have forced the industry on the one hand to face competition at home, and on the other to go abroad to compete there. The energy sector has risen to this ambitious challenge, at the same time developing into an independent industrial sector that can compete in the international market

    Carbon dioxide emissions and heat flow through soil, steam vents and fractures, and steam heated mud pools were determined in the Reykjanes geothermal area, SW Iceland. Soil diffuse degassing of CO 2 was quantified by soil flux measurements on a 600 m by 375 m rectangular grid using a portable closed chamber soil flux meter and the resulting data were analyzed by both a graphical statistical method and sequential Gaussian simulations. The soil temperature was measured in each node of the grid and used to evaluate the heat flow. The heat flow data were also analyzed by sequential Gaussian simulations. Heat flow from steam vents and fractures was determined by quantifying the amount of steam emitted from the vents by direct measurements of steam flow rate. The heat loss from the steam heated mud pools was determined by quantifying the rate of heat loss from the pools by evaporation, convection, and radiation. The steam flow rate into the pools was calculated from the observed heat loss from the pools, assuming that steam flow was the only mechanism of heat transport into the pool. The CO 2 emissions from the steam vents and mud pools were determined by multiplying the steam flow rate from the respective sources by the representative CO 2 concentration of steam in the Reykjanes area. The observed rates of CO 2 emissions through soil, steam vents, and steam heated mud pools amounted to 13.5 ± 1.7, 0.23 ± 0.05, and 0.13 ± 0.03 tons per day, respectively. The heat flow through soil, steam vents, and mud pools was 16.9 ± 1.4, 2.2 ± 0.4, and 1.2 ± 0.1 MW, respectively. Heat loss from the geothermal reservoir, inferred from the CO 2 emissions through the soil amounts to 130 ± 16 MW of thermal energy. The discrepancy between the observed heat loss and the heat loss inferred from the CO 2 emissions is attributed to steam condensation in the subsurface due to interactions with cold ground water. These results demonstrate that soil diffuse degassing can be a more

    Borehole radar measurements with the RAMAC system have been performed in 24 boreholes distributed between the investigation areas Kuhmo Romuvaara, Hyrynsalmi Veitsivaara, Konginkangas Kivetty, Sievi Syyry, and Eurajoki Olkiluoto. The purpose of the borehole radar measurement program has been to investigate the bedrock in the vicinity of the boreholes in order to obtain information about geometry and extent of fracture zones, lithological contacts and other structures. The measurements have been performed as singlehole radar reflection measurements and Vertical Radar Profiling (VRP) measurements, using antennas with 22 MHz frequency range in both configurations. The total measured length in the singlehole radar reflection mode is 13304 meter and in the VRP mode 9200 meter. The VRP measurements are not presented in the report. Radar data from the singlehole reflection measurements are presented as grey scale radar maps after digital filtering with a bandpass filter and a moving average filter. Interpreted zones from the singlehole radar measurements are presented in tables for each borehole. It has been possible to study structures at distances of more than 110 meter from the borehole

    It is essential to gain knowledge on the subglacial hydrological conditions at the glacier bed / bedrock interface when assessing how bedrock fracture zones affect subglacial melt water flow and in which subglacial zones pressurized and oxygen-rich melt water penetrates into the bedrock fracture systems. In the warm-based glacier zones, a part of subglacial melt water will penetrate deep into the fracture systems although the major part of melt water is drained to and beyond the ice margin via subglacial tunnel networks especially in the areas where ice is flowing on the crystalline bedrock. During the last deglaciation phase of the former Scandinavian Ice Sheet, glaciofluvial accumulations were deposited and these sediment accumulations are highly important when picturing the subglacial hydrology of different ice streams during deglaciation in the crystalline bedrock area. The aim of the present work was to map the bedrock fracture zones in the Kylaeniemi area and to shed light on the subglacial hydrology of the Scandinavian Ice Sheet's Lake District Ice Stream that occupied the Kylaeniemi area during the Younger Dryas between ca. 12 500 - 11 600 years ago. The special emphasis within this general aim was to study the relationship between bedrock fracture zones and the routes of subglacial drainage paths. The methods used to map and study bedrock fracture zones and subglacial drainage paths included remotes sensing methods, field observations, ground penetrating radar (GPR) investigations and GIS-based reconstructions. Conventional geological field methods aided by the GPR-method were also used to map bedrock exposures and their structures and to define the type of glaciofluvial sediments and glaciofluvial landform associations. Two main fracture zone sets occur in the study area. The most prominent bedrock fracture zone set trends NW-SE while the other, less prominent fracture zone set is aligned in NE-SW direction.

    Many types of soil-disturbing land use have caused excess sedimentation in Finnish lakes. Identification and quantification of catchment sources of sediment material is crucial in cases where demands for remediation measures are considered. We studied recent (50 yr) sediments of four small rivers, all draining to a reservoir impounded in 1971. Catchments of two of the rivers had had peat mining activities from early 1980s until recently, exposing large areas of peat surfaces to erosion. The water level of the reservoir had risen to the river mouth areas of all rivers, while in each case, the river mouth areas still form riverine narrows separable from the main reservoir, hence collecting sedimentation from their own catchments. The original soils under the reservoir water level could readily be observed in core samples, providing a dated horizon under recent sediments. In addition, we used 137Cs-stratigraphies for dating of samples from original river bed locations. As expected, recent sediments of rivers with peat mining influence differed from others e.g. by high organic content and C:N ratios. Stable isotopes 13C and 15N both correlated with C:N (r = 0.799 and r = -0.717, respectively) and they also differentiated the peat-mining influenced samples from other river sediments. Principal components of the physical-chemical variables revealed clearer distinction than any variables separately. Light-microscopy revealed abundance of leafs of Sphagnum mosses in peat-mining influenced river sediments that were nearly absent from other rivers. Spores of Sphagnum were, however, abundant in all river sediments indicating their predominantly airborne origin. We find that combination of several physical-chemical characters rather than any single variable and microscopy of plant remains can result in reliable recognition of peatland-origin of sediment material when non-impacted sites are available for comparison. Dating of disturbed recent sediments is challenging. River

    This study focuses on commercial waste, which has received less attention than household waste in regards to greenhouse gas emission research. First, the global warming potential (GWP) of commercial waste management was calculated. Second, the impacts of different waste fractions and the processes of waste management were recognised. Third, the key areas on which to focus when aiming to reduce the greenhouse gas emissions of commercial waste management were determined. This study was conducted on the waste generated by a real hypermarket in South-East Finland and included eight different waste fractions. The waste treatment plants were selected based on the actual situation. Three different scenarios were employed to evaluate the environmental impact of managing mixed waste: landfilling, combustion and more accurate source separation. The GaBi software and impact assessment methodology CML 2001 were used to perform a life cycle assessment of the environmental impacts associated with the waste management. The results indicated that the total GWP of commercial waste management could be reduced by 93% by directing the mixed waste to combustion instead of landfill. A further 5% GWP reduction could be achieved by more accurate source separation of the mixed waste. Utilisation of energy waste had the most significant influence (41-52%) on the total GWP (-880 to -860 kgCO 2 -eq./t), followed by landfilling of mixed waste (influence 15-23% on the total GWP, 430 kgCO 2 -eq./t), recycling polyethylene (PE) plastic (influence 18-21% on the total GWP, -1800 kgCO 2 -eq./t) and recycling cardboard (influence 11-13% on the total GWP, 51 kgCO 2 -eq./t). A key focus should be placed on treatment processes and substitutions, especially in terms of substitutions of energy waste and PE plastic. This study also clarified the importance of sorting PE plastic, even though the share of this waste fraction was not substantial. The results of this paper were compared to those of

    Fine particulate matter (PM 2.5 ) emissions from vegetation fires can be transported over long distances and may cause significant air pollution episodes far from the fires. However, epidemiological evidence on health effects of vegetation-fire originated air pollution is limited, particularly for mortality and cardiovascular outcomes. We examined association between short-term exposure to long-range transported PM 2.5 from vegetation fires and daily mortality due to non-accidental, cardiovascular, and respiratory causes and daily hospital admissions due to cardiovascular and respiratory causes in the Helsinki metropolitan area, Finland. Days significantly affected by smoke from vegetation fires between 2001 and 2010 were identified using air quality measurements at an urban background and a regional background monitoring station, and modelled data on surface concentrations of vegetation-fire smoke. Associations between daily PM 2.5 concentration and health outcomes on i) smoke-affected days and ii) all other days (i.e. non-smoke days) were analysed using Poisson time series regression. All statistical models were adjusted for daily temperature and relative humidity, influenza, pollen, and public holidays. On smoke-affected days, 10µg/m 3 increase in PM 2.5 was associated with a borderline statistically significant increase in cardiovascular mortality among total population at a lag of three days (12.4%, 95% CI -0.2% to 26.5%), and among the elderly (≥65 years) following same-day exposure (13.8%, 95% CI -0.6% to 30.4%) and at a lag of three days (11.8%, 95% CI -2.2% to 27.7%). Smoke day PM 2.5 was not associated with non-accidental mortality or hospital admissions due to cardiovascular causes. However, there was an indication of a positive association with hospital admissions due to respiratory causes among the elderly, and admissions due to chronic obstructive pulmonary disease or asthma among the total population. In contrast, on non-smoke days PM 2.5 was

    Basic igneous rocks, containing less than 52% SiO 2 , constitute an important part of the Finnish Archaean and Proterozoic crust. In the Archaean crust exist two units which contain the majority of the basic rocks. The Arcaean basic rocks are metavolcanics and situated in the Greenstone Belts of Eastern Finland. They are divided into two units. The greenstones of the lower one are tholeiites, komatiites and basaltic komatiites. The upper consists of bimodal series of volcanics and the basic rocks of which are Fe-tholeiites, basaltic komatiites and komatiites. Proterozoic basic rocks are divided into seven groups according to their ages. The Proterozoic igneous activity started by the volominous basic magmatism 2.44 Ga ago. During this stage formed the layered intrusions and related dykes in the Northern Finland. 2.2 Ga old basic rocks are situated at the margins of Karelian formations. 2.1 Ga aged Fe-tholeiitic magmatic activity is widespread in Eastern and Northern Finland. The basic rocks of 1.97 Ga age group are met within the Karelian Schist Belts as obducted ophiolite complexes but they occur also as tholeiitic diabase dykes cutting the Karelian schists and Archean basement. The intrusions and the volcanics of the 1.9 Ga old basic igneous activity are mostly encountered around the Granitoid Complex of Central Finland. Subjotnian, 1.6 Ga aged tholeiitic diabases are situated around the Rapakivi massifs of Southern Finland, and postjotnian, 1.2 Ga diabases in Western Finland where they form dykes cutting Svecofennian rocks

    Mining development sites occasionally host complicated aquifer systems with notable connections to natural surface water (SW) bodies. A low-altitude thermal infrared (TIR) imaging survey was conducted to identify hydraulic connections between aquifers and rivers and to map spatial surface temperature patterns along the subarctic rivers in the proximity of the Hannukainen mining development area, northern Finland. In addition to TIR data, stable isotopic compositions ( δ 18O, δD) and dissolved silica concentrations were used as tracers to verify the observed groundwater (GW) discharge into the river system. Based on the TIR survey, notable GW discharge into the main river channel and its tributaries (61 km altogether) was observed and over 500 GW discharge sites were located. On the basis of the survey, the longitudinal temperature patterns of the studied rivers were found to be highly variable. Hydrological and hydrogeological information is crucial in planning and siting essential mining operations, such as tailing areas, in order to prevent any undesirable environmental impacts. The observed notable GW discharge was taken into consideration in the planning of the Hannukainen mining development area. The results of this study support the use of TIR imagery in GW-SW interaction and environmental studies in extensive and remote areas with special concerns for water-related issues but lacking the baseline research.

    The Naukluft Mountains in the Namib Desert are a high rainfall-high discharge area. It sees increased stream-, spring-flow as well as waterfalls during the rainy season. The mountains are a major resource for additional recharge to the Namib and Nama aquifers that are adjacent to the mountains. This paper aimed to highlight the potential vulnerability of the aquifers that surround the Naukluft Mountain area; if the strategic importance of the Naukluft Karst Aquifer (NKA) for bulk water supply becomes necessary. Chloride Mass Balance Method (CMBM) was applied to estimate rainfall available for recharge as well as actual recharge thereof. This was applied using chloride concentration in precipitation, borehole and spring samples collected from the study area. Groundwater flow patterns were mapped from hydraulic head values. A 2D digital elevation model was developed using Arc-GIS. Results highlighted the influence of the NKA on regional groundwater flow. This paper found that groundwater flow was controlled by structural dip and elevation. Groundwater was observed to flow predominantly from the NKA to the south west towards the Namib Aquifer in two distinct flow patterns that separate at the center of the NKA. A distinct groundwater divide was defined between the two flow patterns. A minor flow pattern from the northern parts of the NKA to the north east towards the Nama Aquifer was validated. Due to the substantial water losses, the NKA is not a typical karst aquifer. While the project area receives an average rainfall of 170.36 mm/a, it was estimated that 1-14.24% (maximum 24.43 mm/a) rainfall was available for recharge to the NKA. Actual recharge to the NKA was estimated to be less than 1-18.21% (maximum 4.45 mm/a) reflecting the vast losses incurred by the NKA via discharge. This paper concluded that groundwater resources of the NKA were potentially finite. The possibility of developing the aquifer for bulk water supply would therefore drastically lower recharge

    In Finland a significant portion of energy originates from renewable sources and cogeneration, that is, combined production of electricity and heat. Combined heat and electricity production is typical in the Finnish industry and in the district heating sector. One third of all electricity and 15 % of district heating is produced by cogeneration. District heating schemes provide about 45 % of heat in buildings. Overall efficiency in industry exceeds 80 % and is even higher in the district heating sector. In 1996 25 % of Finland`s primary energy was produced from renewable energy sources which is a far higher proportion than the European Union average of 6 %. Finland is one of the leading users of bioenergy. Biomass including peat, provides approximately 50 % of fuel consumed by industry and is utilised in significant amounts in combined heat and electricity plants. For example, in the pulp and paper industry, by burning black liquor and bark during the production of chemical pulp, significant amounts of energy are generated and used in paper mills. Conservation and efficient use of energy are central to the Finnish Government`s Energy Strategy. The energy conservation programme aims to increase energy efficiency by 10-20 % by the year 2010. Energy saving technology plays a key role in making the production and use of energy more efficient. In 1996 of FIM 335 million (ECU 57 million) spent on funding research, FIM 120 million (ECU 20 million) was spent on research into energy conservation

    Full Text Available The Zeber Kuh prospect area is located southwest of Bardaskan, South Khorasan province, in the northeastern Iran. Lithologically, the area includes Rizu and Soltanieh Formations metamorphosed carbonate rocks, which were intruded by syenogranitic and syenodioritic intrusions. Field observations and laboratory studies such as structural controls of orebody, metasomatic replacement and formation of low temperature H2O-bearing minerals, and the occurrence of magnetite and pyrite associated with chlorite, epidote, calcite, and quartz indicate that  the iron mineralization is low temperature skarn-type. The source of Fe mineralization is probably a younger intrusive rock at depth. Hydrothermal ore fluid was ascended within fault zone and/or contact between the intrusive rock and the  carbonate unit and generated orebody. Iron grade ranges from 54 to 65 wt.% and sulfur value is > 3 wt.%. Magnetite chemistry and Ti, V, Al, Mn, Ni, and Cr contents are similar to skarn deposit. Biotite syenodiorite host rock has hypidiomorphic granular texture and it consists of plagioclase, K-feldspar, biotite, and apatite minerals. Chemically, this intrusive rock is K-series alkaline type, which was generated in within plate zone. This magma is characterized by strong enrichment in LREE, LILE (Rb, Cs, Ba, and K, HFSE (Nb, Zr, and Ti, and P elements. The primary magma is produced by low degree partial melting of garnet lherzolite from asthenospheric to boundary of asthenospheric-lithospheric mantle.

    Full Text Available Myanmar, formerly Burma, is vulnerable to several natural hazards, such as earthquakes, cyclones, floods, tsunamis and landslides. The present study focuses on geomorphologic and geologic investigations of the south-western region of the country, based on satellite data (Shuttle Radar Topography Mission-SRTM, MODIS and LANDSAT. The main objective is to detect areas vulnerable to inundation by tsunami waves and cyclone surges. Since the region is also vulnerable to earthquake hazards, it is also important to identify seismotectonic patterns, the location of major active faults, and local site conditions that may enhance ground motions and earthquake intensities. As illustrated by this study, linear, topographic features related to subsurface tectonic features become clearly visible on SRTM-derived morphometric maps and on LANDSAT imagery. The GIS integrated evaluation of LANDSAT and SRTM data helps identify areas most susceptible to flooding and inundation by tsunamis and storm surges. Additionally, land elevation maps help identify sites greater than 10 m in elevation height, that would be suitable for the building of protective tsunami/cyclone shelters.

    Permafrost degradation substantially impacts hydrological processes in the Source Area of the Yellow River (SAYR). Deepening active layer has directly led to a reduction of surface runoffs, alters the generation and dynamics of slope runoffs and groundwater, leading to a deepening of groundwater flow paths. At present, however, there is only a limited understanding of the hydrological impact mechanisms of degrading permafrost. On the basis of analyzing and evaluating the current states, changing history and developing trends of climate, permafrost and hydrological processes, this program aims at further and better quantifying the nature of these mechanisms linking the degrading permafrost with changing hydrological processes. The key scientific themes for this research are the characterization of interactions between ground freezing-thawing and hydrogeology in the SAYR. For this study, a coupling is made between geothermal states and the occurrences of taliks in river systems, in order to understand how expanding taliks control groundwater and surface-water interactions and how these interactions might intensify or weaken when the climate warms and dries persistently. Numerical models include freeze-thaw dynamics coupled to groundwater and surface flow processes. For the proper parameterization of these models, field and laboratory studies are conducted with a focus on the SAYR. Geophysical investigations are employed for mapping permafrost distribution in relation to landscape elements. Boreholes and water wells and observation sites for the hydrothermal processes and water tables are used for establishing the current thermal state of frozen ground and talik and monitor their changes over time, and serve to ground-truth surface geophysical observations. Boreholes and wellbores, water wells and active layer sites have provided access to the permafrost and aquifer systems, allowing the dating of ground-water and -ice and soil strata for elucidating the regional

    2017-06-01

    Full Text Available China has the largest area of inland geological phosphorus-rich (GPR mountains in the world, where vegetation restoration is key to safeguarding the environment. We reviewed the published literature and collected new data in order to analyze re-vegetation patterns and the status of plant communities in central Yunnan. The aim of our analysis was to suggest future improvements to restoration strategies in GPR mountain regions. Our results showed that spontaneous recovery was the most widespread type of restoration. N-fixing species such as Coriaria nepalensis and Alnus nepalensis play a vital role in succession. In the past, monoculture tree plantation was the primary method used in afforestation activities in central Yunnan; in recent years however, several different methods of restoration have been introduced including the use of agroforestry systems. For practical restoration, we found that spontaneous recovery was capable of delivering the best results, but that during its early stages, restoration results were affected by several factors including erosion risk, the origin of propagates and environmental variation. In contrast, methods employing human-made communities performed better in their early stages, but were constrained by higher costs and vulnerability to degradation and erosion. The use of N-fixing species such as A. nepalensis and Acacia mearnsii in plantations were unsuccessful in restoring full ecosystem functions. The success of restoration activities in GPR mountain regions could be improved through the following measures: (1 developing a better understanding of the respective advantages and disadvantages of current natural and human-engineered restoration approaches; (2 elucidating the feedback mechanism between phosphorus-rich soil and species selected for restoration, especially N-fixing species; (3 introducing market incentives aimed at encouraging specific restoration activities such as agroforestry, and improving the

    Full Text Available The geological, biological and geochemical features of a particular field of hydrothermal vents, discovered in the Panarea Volcanic Complex during a research survey carried out in 2015, are described for the first time. The site, located at 70-80 m depth off the South-western coast of the islet of Basiluzzo, was named Smoking Land for the presence of a large number of wide and high active chimneys and was characterized in terms of dissolved benthic fluxes, associated macrofauna and megafauna communities and preliminary mineralogy and geochemistry of chimney structures. On the whole field, a total of 39 chimneys, different in size and shape, were closely observed and described; 14 of them showed emission of low temperature hydrothermal fluids of marine origin characterized by acidified chemical conditions. The CTD and benthic chamber measurements highlighted that the Smoking Land is able to form a sea water bottom layer characterized by variable acidity and high DIC and trace elements concentrations; these characteristics weaken moving away from the chimney mouths. The SEM-EDS analysis of the collected solid samples revealed a chimney structure principally composed by amorphous and low crystalline Fe-oxyhydroxides of hydrothermal origins. The ROV explorations revealed a wide coverage of red algae (Peyssonnelia spp. colonized by the green algae Flabiella petiolata and by suspension feeders, mainly sponges, but also bryozoans, and tubicolous polychaetes. Although novent-exclusive species were identified, the benthic communities found in association to the chimneys included more taxa than those observed in the surrounding no-vent rocky areas. These first findings evidence a submarine dynamic habitat where geological, chemical and biological processes are intimately connected, making the Smoking Land an important site in terms of marine heritage that should be safeguarded and protected.

    Full Text Available Elevated concentrations of sulphate, chloride, and nickel were discovered in water samples taken from the Töllinperä aquifer in western Finland. The area is located adjacent to the tailings area of the Hitura nickel mine. Earlier studies revealed that the groundwater contamination resulted from tailings-derived mine waters leaking from a tailings impoundment area. The tailings area directly overlies the Weichselian esker system, part of which is the Töllinperä classified groundwater area. The observed groundwater and surface water contamination resulted in a need to characterize the subsurface geology in the whole area of the contaminated esker aquifer. The primary sedimentary units were introduced into a three-dimensional (3-D geologic model of the aquifer made with EarthVision geologic modeling software. The information obtained from the 3-D geological model was then introduced into a numerical groundwater flow model made with MODFLOW code, which was calibrated with MODFLOWP code.The results of this study were used to guide the sealing of the tailings impoundment in order to prevent the further contamination of the Töllinperä aquifer. The groundwater flow model was used to interpret and simulate the flow system, and to provide a plan to safely continue water supply to local inhabitants from the unpolluted parts of the aquifer.

    International Nuclear Information System (INIS)

    2006-01-01

    Close to 80% of the district heat produced in Finland is generated in combined heat and power (CHP) plants. This is a very high figure, and compares favourably with the situation else here, even in neighbouring Sweden, where local CHP facilities only account for 20% of district heat generation, because of the major role played by hydropower and nuclear. District heat is well-established, and has a 48% market share in Finland. Sales are growing by between 1% and 1,5% a year in terms of temperature-corrected offtake volume. This compares to a 50% market share in Sweden. District heat contracts generally follow recommendations drawn up by Finnish Energy Industries in cooperation with the country's competition and consumer protection authorities. This has promoted a consistent level of best practice and prevented unnecessary disputes between suppliers and customers

  13. Licensing process in Finland

    International Nuclear Information System (INIS)

    Tiippana, Petteri

    2011-01-01

    In accordance with the Nuclear Energy Act, the use of nuclear energy constitutes operations subject to license. The licensing process and conditions for granting a license is defined in the legislation. The licenses are applied from and granted by the Government. This paper discusses briefly the licensing process in Finland and also the roles and responsibilities of main stakeholders in licensing. Licensing of a nuclear power plant in Finland has three steps. The first step is the Decision in Principle (DiP). Goal of DiP is to decide whether using nuclear power is for the overall good for the Finnish society. The second step is Construction License (CL) and the goal of CL phase is to determine whether the design of the proposed plant is safe and that the participating organisations are capable of constructing the plant to meet safety goals. The third step is the Operating License (OL) and the goal of the OL phase is to determine whether the plant operates safely and licensee is capable to operate the plant safely. Main stakeholders in the licensing process in Finland are the utility (licensee) interested in using nuclear power in Finland, Ministry of Employment and the Economy (MEE), Government, Parliament, STUK, the municipality siting the plant and the general public. Government grants all licenses, and Parliament has to ratify Government's Decision in Principle. STUK has to assess the safety of the license applications in each step and give statement to the Ministry. Municipality has to agree to site the plant. Both STUK and the municipality have a veto right in the licensing process

    Ruuskanen, A.T.; Jaervinen, P.J.

    1984-01-01

    Energy issues are at present heavily debated in Finland. Public discussion is very emotional and biased against nuclear power. The undetermined situation together with the need for a decision on increasing the nuclear capacity led Imatran Voima Oy (Imatra Power Company) to measure the prevailing attitudes. The paper discusses the energy opinion surveys recently made in Finland. The general results give evidence of the changes occurring in the values of life. Environmental issues and the purity of energy production are seen as the most important factors of energy policy. Low price or availability and reliability are considered less important. The results of the surveys show, however, that people think that more electricity will be needed in the future. Natural gas, peat and hydroelectric power are most favoured. The attitude towards the use of coal and nuclear power is clearly more diffuse. In the survey, 21% want to increase the share of nuclear power, 32% want to keep its use at the present level and 35% want to reduce it. This 35% includes the one-fifth of the population that would like to abandon nuclear power altogether. Nuclear wastes and accidents are considered the most important factors contributing to the formation of attitudes towards nuclear energy. The other main factors are discussed in the paper. A great desire for information on energy policy together with personal decision making interests reflect the general attitude in Finland also. Totally incorrect information on nuclear energy is, however, surprisingly prevalent, which makes opposition to nuclear power understandable. All these factors make taking a decision on a fifth nuclear power plant in Finland difficult. (author)

    Finland currently generates about 40% of its electricity from nuclear power. This achievement of worldwide record magnitude is based on long-lasting efforts to build and maintain the competent infrastructure and close international cooperation required by this demanding technology. This booklet published by the Finnish Atomic Energy Commission gives an overview of nuclear energy and related organizations in Finland. It describes the utility companies and nuclear power production, the manufacturing industry and its export potential, research and educational activities and the legal framework and authorities for nuclear safety and administration. International cooperation has been essential for Finland in developing its nuclear energy capacity and appreciation is espressed to many countries and international organizations which have contributed to this. At the same time Finnish organizations are willing to share the experiences and know-how they have gained in building nuclear power in a small country. This is a road which will be followed by many other countries in the decades to come. It is hoped that this booklet will also help to open new channels of cooperation in such efforts

    Full Text Available This article examines the commodification of Russian in Finland, where recent decades have seen a sharp rise in the size of the Russian-speaking population and the number of tourists from Russia. We particularly consider the use of Russian in the fields of traditional and medical tourism, education, and culture - all of them areas where Russian tourists show a strong preference for services in their native language. The need to provide a variety of services in Russian means that proficiency in Russian is a sig-nificant asset on the job market, both for immigrants and for the relatively small number of Finns who can speak the language. We also note that there is considerable demand among Russian-speaking parents in Fin-land for educational services to supplement their children’s school education.

    2017-04-01

    The soil element concentrations regionally vary a lot in Finland. Mostly this is caused by the different bedrock types, which are reflected in the soil qualities. Geological Survey of Finland (GTK) is carrying out geochemical baseline studies in Finland. In the previous phase, the research is focusing on urban areas and mine environments. The information can, for example, be used to determine the need for soil remediation, to assess environmental impacts or to measure the natural state of soil in industrial areas or mine districts. The field work is done by taking soil samples, typically at depth between 0-10 cm. Sampling sites are chosen to represent the most vulnerable areas when thinking of human impacts by possible toxic soil element contents: playgrounds, day-care centers, schools, parks and residential areas. In the mine districts the samples are taken from the areas locating outside the airborne dust effected areas. Element contents of the soil samples are then analyzed with ICP-AES and ICP-MS, Hg with CV-AAS. The results of the geochemical baseline studies are published in the Finnish national geochemical baseline database (TAPIR). The geochemical baseline map service is free for all users via internet browser. Through this map service it is possible to calculate regional soil baseline values using geochemical data stored in the map service database. Baseline data for 17 elements in total is provided in the map service and it can be viewed on the GTK's web pages (http://gtkdata.gtk.fi/Tapir/indexEN.html).

    Solar ultraviolet radiation is damaging for living organisms due to its high energy pro each photon. The UV radiation is often separated into three regions according to the wavelength: UVC (200-280 nm), UVB (280-320 nm) and UVA (320-400 nm).

    Solar ultraviolet radiation is damaging for living organisms due to its high energy pro each photon. The UV radiation is often separated into three regions according to the wavelength: UVC (200-280 nm), UVB (280-320 nm) and UVA (320-400 nm). The most hazardous part, UVC is absorbed completely in the upper atmosphere by molecular oxygen. UVB radiation is absorbed by atmospheric ozone partly, and it is reaching Earth`s surface, as UVA radiation.

    Full Text Available Estima-se que as áreas invadidas por algaroba – Prosopis juliflora (Sw. DC. (Fabaceae no semi-árido nordestino já ultrapassam um milhão de hectares. O presente trabalho objetivou estudar os impactos da invasão de P. juliflora sobre a fitodiversidade e a estrutura do componente arbustivo-arbóreo, em remanescentes de caatinga no Estado da Paraíba. Usando-se o método de parcelas, foram amostrados quatro ambientes, nos quais os indivíduos de todas as espécies arbustivas e arbóreas foram inventariados e medidos, estimando-se os parâmetros estruturais das comunidades. Também foi calculada a diversidade, pelo índice de Shannon-Wiener (H’ e o índice de impacto ambiental deexóticas (IIAE. No total, foram amostradas 19 famílias, 35 gêneros e 39 espécies. A invasora foi responsável por mais de 70% de toda a estrutura dos ambientes inventariados. A baixa diversidade e o elevado valor de impacto ambiental obtidos para os ambientes invadidosrevelaram, conjuntamente com os dados de estrutura das populações, os graves impactos que P. juliflora provoca nas comunidades invadidas. Evidencia-se com isso a formação de sistemas monodominados pela espécie invasora, o que revela a necessidade de controle efetivo de P. juliflora para se proteger o patrimônio genético autóctone.It is estimated that invader populations of algaroba Prosopis juliflora (Sw.

    The lithostratigraphic sequence of the Upper Rotliegende rocks of the SE-flank of the Palatinate anticline (Saar-Nahe-basin, SW Germany) is described using as index horizons six principal rhyolitic tuff layers (1-VI) and several basic to intermediate lava flows. Coal and bentonite beds are developed at the base of rhyolite tuff III at the Kornkiste near Schallodenbach. In this basal sequence anomalous U/sub 3/O/sub 8/, Cu, Pb, Zn contents have been detected. Cu occurs in part as azurite and malachite. The major amount of the investigated elements appears to occur in form of organic complexes or compounds in the coals. In addition these elements seem to have been absorbed by the bentonite clay minerals. The elements U, Cu, Pb show a clear positive correlation between each other wheres Zn correlators negatively with these elements. The U-Cu-Pb-Zn-enrichment is believed to have been caused by descending aqueous solutions.

    The increase in maternal age has been well documented in Western societies, but information on paternal age trends is scarce. The aim of this study was to investigate changes in age and other background characteristics of first-time fathers in Finland in the period 1987-2009. A random 60% sample of first-time fathers in each year from 1987 to 2009 was obtained from Statistics Finland (n=344,529). Five-year intervals were used (three years in 1987-1989). Sociodemographic characteristics of older first-time fathers (⩾40 years) were compared over time using logistic regression. In the logistic regression, immigrants were excluded from the study population as they may have had children before migrating to Finland. The mean age of first-time fathers increased from 28.7 to 30.4 years in 1987-2009. The change was greatest in the Capital Region and smallest in Northern and Eastern Finland. Fatherhood at the age of ⩾40 years doubled from 3.1% to 6.8%. From 2005 to 2009, men who lived in rural areas and the Capital Region, had a long education, were divorced or widowed, had been born in a rural area and were native Finnish speakers, were more likely than other men to be old when they became fathers. CONCLUSIONS DURING THE STUDY PERIOD, THE AVERAGE AGE OF FIRST-TIME FATHERS INCREASED BY TWO YEARS FURTHER STUDIES ARE NEEDED TO EXAMINE WHETHER DELAYS IN FIRST-TIME FATHERHOOD AFFECT FERTILITY, CHILD HEALTH AND THE USE OF SOCIAL AND HEALTH SERVICES. © 2015 the Nordic Societies of Public Health.

    1996-12-31

    Finland tops the statistics for the industrialised world in the utilisation of bioenergy. In 1995 bioenergy, including peat-fired heat and power, accounted for 20 % of the total energy consumption. The declared goal of the government is to increase the use of bioenergy by not less than 25 % (1.5 million toe by the year 2005). Research and development plays a crucial role in the promotion of the expanded use of bioenergy in Finland. The aim is to identify and develop technologies for establishing and sustaining economically, environmentally and socially viable bioenergy niches in the energy system

    Air toxics research in Finland has developed rapidly in recent years. Though they have no enormous environmental problems in Finland, the author feels that they have to increase their knowledge of more efficient energy production and control technology. Enormous emission sources are around them, but there are also huge markets for know-how and technology in the energy sector. Two Finnish national research programs will ensure the continuity of the development efforts concerning combustion technology and environmental aspects at both theoretical and practical levels

    International Nuclear Information System (INIS)

    1961-01-01

    The basic circumstances which stimulated Finland's interest in nuclear power are summarized in the report as follows: 'In Finland the main power resource has been, and still is, water power. It is clear, however, that the hydro potential is insufficient to cover the increasing consumption over a long period of time. Already about one half of this potential has been exploited. Thus the country will necessarily have to consider the utilization of thermal power to an increasingly large extent. There is no indigenous coal or oil. For this reason it has become necessary to investigate realistically the possibilities offered by nuclear power'

    1992-01-01

    The Finnish State has traditionally controlled the import of electricity, larger related investments and pricing. Lately, a market orientated economic policy has influenced energy policy and the amount of state control has gradually decreased. Decisions have yet to be made with regard to the fifth nuclear power reactor. The paper deals briefly with the subjects of the electric power, natural gas and oil markets. Finland's transmission network has connections to the former Russia and the Baltic countries. According to agreements within the European Community, Finland must now make changes in its electric power supply structure. Competition will be encouraged and monopolies discouraged. Pricing shall be transparent, and power plants must present written documentation for their management system, price regulations etc. A law must be passed to legitimate trade across the country's borders. Emphasis will be laid on energy conservation and energy research and consultant services. It is claimed that Finland's level of technology in this area lives up to international standards. (AB)

    The ownership structure of Finland's leading natural gas company, Gasum, changed fundamentally in 1999, and the company is now no longer a subsidiary of Fortum Corporation. 'Our new strong and broad ownership base will enable us to develop the natural gas business and pipeline network in Finland in response to the requirements of our Finnish customers', says Antero Jaennes, Gasum's Chairman and CEO, who stresses that Gasum is committed to remaining the leading developer of the Finnish natural gas market and the number-one gas supplier. Natural gas usage in Finland in 1999 totalled 3.9 billion m 3 (38.7 TWh), unchanged from 1998. Natural gas accounted for 11% of Finland's total primary energy need, as it did in 1998. The proportion of natural gas used in district heating rose by 2% to 36%, and moved down 2% in power generation to 10%. Industry's use of natural gas fell 1% to 17%. 75% of natural gas was used in combined heat and power (CHP) generation in industry and district heating. In 2000, Gasum expects to sell 4 billion m 3 of natural gas (40 TWh)

    Concentration distributions of natural decay chains 4n+2 and 4n+3 in crystalline rock intersected by a natural fracture were measured. Calcite coating on the same fracture surface was dated. Material properties of the rock matrix, and nuclide concentrations in groundwater were measured. The interpretation of the concentration distributions is based on the classical matrix diffusion concept. Although support was obtained, this calibration exercise does not yet validate the model. Besides initial and boundary conditions, matrix properties are uncertain due to the small amount of rock material. Experimental sorption data was not available, but its importance and the need for systematic studies was demonstrated. (orig.) (10 refs., 5 figs., 5 tabs.)

    This report is mainly a summary report of the studies done 1986 - 1997 by the Geological Survey of Finland/Nuclear Waste Disposal Research on postglacial faulting (PG-faults) and recent bedrock movements. Most of the results have already been published in other YST-reports in Finnish. The first part of the report deals with the postglacial faults in Finland and in the second part the problems connected with the origin and age of paleoseismic dislocations found in Russian Karelia are described. The final part deals with the present vertical and horizontal movements of Finnish bedrock. The Pasmajaervi PG-fault is the most thoroughly studied PG-fault in Finland. Around the fault lineament interpretations and geophysical ground measurements have been done and the fault zone has been penetrated with two drill holes. Three levelling networks and one GPS-network have been established for revealing any recent movements of the PG-fault area. Other PG-faults studied, but not in the same detail, are Venejaervi, Ruostejaervi, Suasselkae and Vaalajaervi PG-faults. The PG-faults in Finland strike in the SW-NE direction and dip to the SE with the exception of the Vaalajaervi PG-fault. It strikes in the NW-SE direction. The dip direction is unknown. The length of the PG-faults is 4-36 km and the scarp height 0-12 m. PG-faults are reverse faults and they are located in old, reactivated fracture zones. The results of drillings and resistivity soundings in the Pasmajaervi PG-fault indicate, that the dip angle of 45 deg in the surface becomes more gentle with the increasing depth. This result may be important from a technical point of view when designing nuclear waste repositories. The strike directions of the PG-faults are perpendicular with the direction of prevailing horizontal maximum stress. The structure and location of the PG-faults is in accordance with the model presented by Muir Wood for the origin of PG-faults. The exceptional direction of the Vaalajaervi PG-fault is

    2013-01-01

    Shrub expansion has been observed widely in tundra areas across the Arctic. This phenomenon has been partially attributed to increasing temperatures over the past century. However, relationships among shrub expansion, grazing, and human disturbance have been studied little. SW Greenland...... is a subarctic to low-arctic region with a long and complex land-use history and only modest temperature increases over the past 50 years (0.2 °C decade-1), but changes in shrub cover have not previously been studied in this region. We compiled historical photographs of vegetation in SW Greenland (1898......–1974) and repeated the photos in 2010 and 2011. Sixty-four photo pairs were cropped into 133 smaller units and classified by aspect, substrate stability, muskoxen grazing, and human disturbance. The photo material was evaluated by 22 experts with respect to changes in shrub cover, revealing a general increase across...

  6. Fuel cycle management in Finland

    1987-01-01

    Both Finnish utilities producing nuclear power - Imatran Voima Oy (IVO) and Teollisuuden Voima Oy (Industrial Power Co. Ltd, TVO) - have created efficient fuel cycle management systems. The systems however differ in almost all respects. The reason is that the principal supplier for IVO is the Soviet Union and for TVO is Sweden. A common feature of both systems at the front end of the cycle is the building of stockpiles in order to provide for interruptions in fuel deliveries. Quality assurance supervision at the fuel factory for IVO is regulated by the Soviet Chamber of Commerce and Industry and a final control is made in Finland. The in-core fuel management is done by IVO using codes developed in Finland. The whole IVO fuel cycle is basically a leasing arrangement. The spent fuel is returned to the USSR after five years cooling. TVO carries out the in-core fuel management using a computer code system supplied by Asea-Atom. TVO is responsable for the back end of the cycle and makes preparations for the final disposal of the spent fuel in Finland. 6 refs., 2 figs

  7. Nuclear power situation in Finland

    Miettinen, J K

    1976-01-01

    Finland plans to have its future energy policy as well-balanced and economical as possible. Dependence on oil has to be reduced and savings have to be achieved wherever possible. Some growth of energy demand will be inevitable, and most of this growth has to be nuclear. Practically all hydropower that can be reasonably exploited is being utilized already. Finland has an abundance of peat, but it can be economically used only as a regional source of energy. This leaves, as the only real alternatives for the coming decennia, coal and fission; of the two, fission is evidently the better choice. Although other forms of energy such as fusion, solar, tidal, and wind energy have to be studied as longer-range alternatives. Four nuclear power plants are presently under construction in Finland and at least a few additional ones will evidently be built before 1990. Several of them will probably be of the combined district heat and electricity-producing type. The planning of nuclear energy has recently become complicated due to financing difficulties, uncertainties regarding long-range fuel services, and public opposition. The latter is partly caused by lack of information, partly by fears of a change of life-style in communities near the planned power plant sites. (From Conclusions)

  8. Fuel reliability experience in Finland

    Four nuclear reactors have operated in Finland now for 35-38 years. The two VVER-440 units at Loviisa Nuclear Power Plant are operated by Fortum and two BWR’s in Olkiluoto are operated by Teollisuuden Voima Oyj (TVO). The fuel reliability experience of the four reactors operating currently in Finland has been very good and the fuel failure rates have been very low. Systematic inspection of spent fuel assemblies, and especially all failed assemblies, is a good practice that is employed in Finland in order to improve fuel reliability and operational safety. Investigation of the root cause of fuel failures is important in developing ways to prevent similar failures in the future. The operational and fuel reliability experience at the Loviisa Nuclear Power Plant has been reported also earlier in the international seminars on WWER Fuel Performance, Modelling and Experimental Support. In this paper the information on fuel reliability experience at Loviisa NPP is updated and also a short summary of the fuel reliability experience at Olkiluoto NPP is given. Keywords: VVER-440, fuel reliability, operational experience, poolside inspections, fuel failure identification. (author)

    Aerial measurements were performed to determine the {sup 137}Cs soil contamination in a given region to detect unknown radiation sources and to assess their activity. For these measurements a computerized gamma ray spectrometer, equipped with a high purity Ge-semiconductor detector and a 12 l volume Nal(Tl)-detector was used. HPGe-detector measurements from different altitudes over area I were done to test and re-calibrate the aerial measuring system. The known {sup 137}Cs contamination of (50.7 {+-} 5.2) kBq m{sup -2} could be confirmed by the measured value of (57 {+-} 10) kBq m{sup -2}. the Nal(Tl)-detector was re-calibrated at that site for further {sup 137}Cs measurements over area II. The area II was surveyed from an altitude of about 70 m and at a parallel line distance of 150 m at an flying speed of 100 km h{sup -1} to determine the {sup 137}Cs soil contamination. The measuring time was two seconds for the Nal(Tl)-detector. For the spectra measured with the HPGe-detector, a measuring time of 30 s each was chosen. From the Nal(Tl)-measurements, a mean {sup 137}Cs value of (60 {+-} 20) kBq m{sup -2} was determined with a maximum value of 90 kBq m{sup -2}. The corresponding values measured by HPGe-detector were (70 {+-} 20) kBq m{sup -2} and 120 kBq m{sup -2}, respectively. For the evaluation of the HPGe-spectra a depth distribution parameter {alpha}/{rho} = (0.44 {+-} 0.21) cm{sup 2} g{sup -1} for {sup 137}Cs was used measured from soil samples. From data measured with the Nal(Tl)-detector during flights over area III, three{sup 60}Co-sources and one {sup 137}Cs source could be detected, localized and their activity assessed. By HPGe-detector measurements, only scattered {sup 192}lr radiation was registered. (au).

    2009-01-01

    The aim of my research was to study the introduction of nuclear power in Finland with special focus on the domestic engineering works industry. I wanted to find out what really happened during this long process, which I consider to be unique. I also tried to clearfy the reasons why it came about at all, and why it developed in such a peculiar way. My basic research questions were: (a.) When and how was nuclear power introduced in Finland? (b.) Which were the reasons for this introduction and which were the results? (c.) Which was the role of the domestic engineering works industry? I started the investigation by exploring the original situation in Finland and also in the countries which came to be a primus motor for the development. I studied the relevant literature and interviewed quite a few of the persons who in a decisive way had an influence on the long and chaotic process which led to the introduction of nuclear power in Finland. When describing the different phases in the development I stayed in principle within the historic framework, although I diverged from a strict chronological order when necessary. Neither did I in my investigation take a neutral stance regarding the two large projects that had a central position in the introduction, namely the nuclear power plants in Lovisa and in Olkiluoto. The Lovisa project implied a greater challenge and it was also more important to the domestic industry than Olkiluoto. It therefore got more attention than Olkiluoto. Oy Finnatom Ab (managed by me 1975-2001), due to its role as a spokesman for the Finnish nuclear engineering works industry, occupied a central position in my investigation. The start of the introduction may psychologically be dated to the startup in 1958 of the Ydin Exponential pile, YXP, and in 1962 of Finland Reactor I, FiR I, and the end to the signing in 1982 by Industrins Kraft, ASEA and Asea-Atom of the acceptance protocol for Olkiluoto and the final permits for Lovisa, granted by the

    The rapid changes and crises in the field of energy during the 1970s and 1980s have forced us to examine the use of energy more critically and to look for new ideas. Seasonal aquifer thermal energy storage (T < 100/sup 0/C) on a large scale is one of the grey areas which have not yet been extensively explored. However, projects are currently underway in a dozen countries. In Finland there have been three demonstration projects from 1974 to 1987. International co-operation under the auspices of the International Energy Agency, Annex VI, 'Environmental and Chemical Aspects of Thermal Energy Storage in Aquifers and Research and Development of Water Treatment Methods' started in 1987. The research being undertaken in 8 countries includes several elements fundamental to hydrochemistry and biochemistry.

  13. Structural control on gold mineralization in the Satulinmäki and Riukka prospects, Häme Schist Belt, southern Finland

    Full Text Available The Satulinmäki and Riukka prospects located in the Häme Schist Belt in southern Finland are dominated by mafic and intermediate to felsic metavolcanic rocks of the Forssa Group formed in a continental arc setting. This magmatic belt formed some 1890–1880 Ma ago and has been deformed during the Svecofennian orogeny. The dominant penetrative foliation is represented by Sn+1, which is axial planar to cm- to dm-scale iscolinal Fn+1 folds and thus parallel to the layering Sn. Associated ductile shearing might reflect early thrusting. Dn+2 post-dating peak metamorphism is characterized by small-scale to regional-scale refolding of Fn+1 folds around ~SW-NE fold axes. This phase is transitional to development of SW-NE to WSW-ENE and NW-SE striking shear zones and faults formed due to dextral transpressionduring Dn+3 at retrograde conditions crossing the brittle-ductile transition. Many mineralized quartz veins have formed during this event. Later faults and quartz veins and reactivation of pre-existing structures during Dn+4 indicate rotation of the stress field to ~NESWoriented compression. A clear ~SW-NE trend of sulphide mineralization and elevated gold contents and the spatial association to Dn+3 quartz veins, shear zones and faults suggest a strong structural control, typical of orogenic gold deposits, and that mineralization took place during Dn+3. The controlling structures, (i WSW-ENE to SW-NE shear zones and faults and (ii NW-SE oriented fault, are second and third order structures to major regional-scale shear zones. The fault zones and their intersection points impart a directional permeability so that the mineralising fluids were channelled along dilatant zones. Approximately (WNW-(ESE trending faults being (reactivated as extensional faults or dilatant shear planes during Dn+3 transpression with WNW-ESE to NW-SE oriented compression direction could have acted as conduits for fluids during upward flow from deeper crustal level.

    In Finland, licensing for new nuclear power is ongoing. The political approval is to be completed in 2010. Fennovoima's project is unique in various ways: (i) the company was established only in 2007, (ii) its ownership includes a mixture of local energy companies, electricity-intensive industries and international nuclear competence through E.ON, and (iii) it has two alternative greenfield sites. There are five prerequisites for a successful nuclear power project in a transparent democracy of today: (1) need for additional power capacity, (2) actor prepared to invest, (3) established competence, (4) available site, (5) open communications, and (6) favorable public opinion.

    On the morning of the 1st of November of 1755 a major earthquake struck offshore the Southwest Iberian margin. This was the strongest earthquake ever felt in Western Europe. The shake, fire and tsunami devastated Lisbon, was felt as far as Finland and had a profound impact on the thinkers of that time, in particular on the Enlightenment philosophers such as Voltaire, Rousseau and Kant. The Great Lisbon Earthquake is considered by many as the event that marks the birth of modern geosciences; and made of this region one of the most well studied areas in the world. After the 1755 earthquake, Kant and others authors wrote several treaties dealing with the causes and dynamics of earthquakes and tsunamis and were close to identify some key elements of what we now call plate tectonics. More than two hundred years later, in the year of 1969, the region was struck by another major earthquake. This was precisely during the period in which the theory of plate tectonics was being built. Geoscientists like Fukao (1973), Purdy (1975) and Mackenzie (1977) immediately focused their attention in the area. They suggested that these events were related with "transient" subduction of Africa below Iberia, along the East-West Azores-Gibraltar plate boundary. Several years later, Ribeiro (1989) suggested that instead of Africa being subducted below Iberia, it was the West Iberian passive margin that was being reactivated, a process that may, in time, lead to the formation of a new subduction zone. In the turning of the millennium, a subducting slab was imaged bellow the Gibraltar Straits, a remanent of the Western Mediterranean arc system that according to Gutscher et al. (2002) was related with ongoing subduction. Recently, it was proposed that a causal link between the Gibraltar subduction system and the reactivation of the SW Iberian margin might exist. In addition, the large-scale Africa-Eurasia convergence is inducing compressive stresses along the West Iberian margin. The margin

    Faced with considerable challenges related to its geography and size, Finland's sound energy policies do much to overcome its situation. The country leverages its small market where it can - such as by adopting or harmonising with EU directives and policies. To counter its relative isolation, Finland strengthened its position by becoming part of the larger Nordic electricity market and enhancing energy linkages. At the core, however, the country ensures energy security by relying on transparency and sound market signals to investors and customers, as well as by making good use of domestic sources of biomass and nuclear. As Finland continues to refine and enhance its energy policy, there are some areas that warrant special attention. As nearly all fossil fuels are imported and all natural gas comes through a single interconnection, the government should continue to explore ways to diversify import sources and routes. The new nuclear power plant currently being built - the first in a liberalised market - will help safeguard energy security, though the construction delays necessitate continued monitoring. Subsidies for peat, a fuel in abundance in Finland, should be reconsidered, as they do not enhance energy security. On the other hand, the government should continue to explore ways to expand new renewables, building on the current stock of biomass and hydro. This book takes an in-depth look at Finland's energy policy today and, through comparisons with good examples in other IEA countries, provides critiques and recommendations for improvements to guide the country towards a sustainable energy future. While the review provides comprehensive coverage of all topics, this thematic report highlights energy efficiency and energy R and D.

    Full text: In September 2003, following the identification of a house near Castleisland in County Kerry (Sw Ireland) with a seasonally adjusted annual average radon concentration of 49,000 Bq/m{sup 3}, the Radiological Protection of Ireland (R.P.I.I.) undertook to carry out a localised radon survey, the so-called 'Castleisland Radon Survey' (C.R.S.). The aim was to investigate the possibility that similarly extreme radon concentrations could be present in other houses in the surrounding area. A studied area of 400 km{sup 2} was designated around the town of Castleisland, divided in four 10 x 10 km{sup 2} grid squares, and all of the approximately 2,500 householders living in this area were invited to participate. Four hundred and eighteen householders responded to the invitation (17% response rate) but only 383 completed the survey. Fourteen percent of these 383 homes were found to have an annual average radon concentration above the Irish national Reference Level for domestic dwellings of 200 Bq/m{sup 3} while 2% were found to be above 800 Bq/m{sup 3}. An arithmetic mean of 147 Bq/m{sup 3} and a geometric mean of 70 Bq/m{sup 3} were calculated for the four studied grid squares. These can be compared with the respective values of 98 and 56 Bq/m3 calculated for the same area by the Irish National Radon Survey (N.R.S.). Similar trends are observed on a grid square by grid square basis where in one of them in particular, the C.R.S. allowed us to predict that 21% of all houses would have radon concentrations in excess of 200 Bq/m{sup 3}, against 6% predicted by the N.R.S.. This clearly indicates that the extent of the radon problem in the area has been underestimated by the N.R.S.. Two of the four grid squares investigated are currently designated as High Radon Areas (where 10% or more of all houses are predicted to exceed 200 Bq/m{sup 3}) based on the results from the N.R.S.. If one was to use predictions based on the results from the C.R.S., all four grid

  5. LiDAR and 2D Electrical Resistivity Tomography as a Supplement of Geomorphological Investigations in Urban Areas: a Case Study from the City of Wrocław (SW Poland)

    Kasprzak, Marek; Traczyk, Andrzej

    2014-06-01

    In urbanized areas, particularly in lowland terrains and floors of large river valleys, the natural land configuration is often hard to recognize due to a long history of human activity. Accordingly, archaeological works in cities, which supply knowledge on settlement conditions, are usually accompanied by geological and geomophological research. Lately, data from light detection and ranging (LiDAR) have become a valuable source of information on urban land configuration. Geophysical methods are also becoming increasingly popular in background studies. The paper presents a method of using and linking these sources of spatial information about landforms in such areas. The main aim is to identify to what extent these complementary sources of data and the proposed method can be used in such a specific environment to reconstruct natural, buried terrain morphology. The city of Wrocław in Central Europe serves as an example. To this end geomorphometric studies were conducted with the use of digital elevation models (DEMs) based on LiDAR scanning and derivated land-surface parameters—SAGA Wetness Index, Channel Network Base Level and Altitude above Channel Network. The study also involved determining morphological edges and measurements of the meanders of the Odra, as well as expanding information on the spatial distribution of alluvia and the structure of slope breaks. To this end, geophysical measurements were conducted using the Two-Dimensional Electrical Resistivity Tomography method. Additionally, five typical sequences of man-made ground present within the perimeter of the city were distinguished. As a result, a map of the main landforms of Wrocław is presented. Finally, we argue that although high resolution DEM and derivate land-surface parameters are very useful in terrain analysis, places with thick man-made ground or strongly levelled areas must be recognized by geoarchaeological excavations or geological bore holes. The geophysical survey is useful to

Arctic ecosystems are considered to be particularly vulnerable to climate change. Expansion of shrubs has been observed widely in tundra areas across the Arctic......, and has a range of ecosystem effects where it occurs. Shrub expansion has to a large extend been attributed to increasing temperatures over the past century, while grazing and human disturbance have received less attention. Alnus viridis ssp. crispa is a common arctic species that contributes...... to increasing shrub cover. Despite this, there is only limited experimental evidence that growth of the species responds to warming. Plant populations in fragmented and isolated locations could face problems adapting to a warming climate due to limited genetic variation and restricted migration from southern...

    The study measured the indoor radon concentration in the dwellings of 3074 persons, selected randomly from the central population register of Finland. Alpha track detectors and two consecutive half year measuring periods were used. The national mean of indoor radon concentration for persons living in low-rise residential buildings as well as blocks of flats was 145 and 82 Bq/m 3 , respectively. The mean for the total population was 123 Bq/m 3 . Based on the decision of the Ministry of Social Affairs and Health in 1992, the indoor radon concentration should not exceed 400 Bq/m 3 in already existing houses, the target for new construction being less than 200 Bq/m 3 . According to the study, the percentage of the Finnish population living in houses with an indoor radon concentration exceeding 200, 400 and 800 Bq/m 3 was 12.3 %, 3.6 % and 1.0 %

  8. The biomass energy market in Finland

    In 2001, it was estimated that the Finnish biomass market was in excess of 235 million dollars. The development of renewable energy, with special emphasis on biomass, was supported by the development of an energy strategy by the government of Finland. The installed capacity of biomass in Finland in 2002 was 1400 megawatt electrical (MWe). Extensive use of combined heat and power (CHP) is made in Finland, and district heating (DH) systems using biomass are gaining in popularity. Wood-based biomass technologies, retrofits to fluidized bed combustion, and wood procurement technologies were identified as the best opportunities for Canadian companies interested in operating in Finland. A country with high standards, Finland seems to look favorably on new innovative solutions. Joint ventures with Finnish companies might be an excellent way for Canadian companies to gain a foothold in Finland and expand into the European Union, the Nordic countries, the Baltic, Russia and the Central and Eastern European markets. It was further noted that Finland is one of the leading exporters of biomass technology in the world.

    Finland covers an area of 337,000 skm. One third of the country lies north of the northern polar circle. 31,613 skm are covered by lakes. 71% of the landscape are covered by coniferous -wood. Climatlcal conditions are continental. The topography of the country is gently rolling with highest elevations of 300 m in the northern part. The most interesting geological units for uranium are Karelian, marginal meta-sediments, mainly quarzites and conglomerates but also schists. These schists are intruded by orogenlc plutonic rocks which are 1800-My-old. Potassium granites are common adjacent to the contact of the Pre-karelian basement (2500 My). In addition to these geological environment uranium and thorium minerals have been found in a large carbonatite in northern Finland, which is explored now

    Coastal urbanization is rapidly expanding worldwide while its impacts on seaweed communities remain poorly understood. We assessed the impact of urbanization along an extensive latitudinal gradient encompassing three phycogeographical regions in the SW Atlantic. Human population density, number of dwellings, and terrestrial vegetation cover were determined for each survey area and correlated with diversity indices calculated from seaweed percent cover data. Urban areas had significantly lower calcareous algal cover (-38%), and there was significantly less carbonate in the sediment off urban areas than off reference areas. Seaweed richness averaged 26% less in urban areas than in areas with higher vegetation cover. We observed a remarkable decline in Phaeophyceae and a substantial increase of Chlorophyta in urban areas across a wide latitudinal gradient. Our data show that coastal urbanization is causing substantial loss of seaweed biodiversity in the SW Atlantic, and is considerably changing seaweed assemblages. Copyright © 2013 Elsevier Ltd.

    2015-09-01

    This paper describes a testing framework for critical space SW named Technical Specification Validation Framework (TSVF). It provides a powerful and flexible means and can be used throughout the SW test activities (test case specification & implementation, test execution and test artifacts analysis). In particular, tests can be run in an automated and/or step-by-step mode. The TSVF framework is currently used for the validation of the Satellite Control Software (SCSW), which runs on the Meteosat Third Generation (MTG) satellite on-board computer. The main purpose of the SCSW is to control the spacecraft along with its various subsystems (AOCS, Payload, Electrical Power, Telemetry Tracking & Command, etc.) in a way that guarantees a high degree of flexibility and autonomy. The TSVF framework serves the challenging needs of the SCSW project, where a plan-driven approach has been combined with an agile process in order to produce preliminary SW versions (with a reduced scope of implemented functionality) in order to fulfill the stakeholders needs ([1]). The paper has been organised as follows. Section 2 gives an overview of the TSVF architecture and interfaces versus the test bench along with the technology used for its implementation. Section 3 describes the key elements of the XML based language for the test case implementation. Section 4 highlights all the benefits compared to conventional test environments requiring a manual test script development, whereas section 5 concludes the paper.

    This work aims to develop and integrate new -omics tools that would be applicable to different ecosystem types for a technological updating of environmental evaluations. We used a 2nd-generation (iTRAQ-8plex) proteomic approach to identify/quantify proteins differentially expressed in the liver of free-living Mus spretus mice from Doñana National Park or its proximities. Mass spectrometry was performed in an LTQ Orbitrap system for iTRAQ reporter ion quantitation and protein identification using a Mus musculus database as reference. A prior IEF step improved the separation of the complex peptide mixture. Over 2000 identified proteins were altered, of which 118 changed by ≥ 2.5-fold in mice from at least two problem sites. Part of the results obtained with the iTRAQ analysis was confirmed by Western blot. Over 75% of the 118 proteins were upregulated in animals captured at polluted sites and only 16 proteins were downregulated. Upregulated proteins were involved in stress response; cell proliferation and apoptosis; signal transduction; metastasis or tumour suppression; xenobiotic export or vesicular trafficking; and metabolism. The downregulated proteins, all potentially harmful, were classified as oncoproteins and proteins favouring genome instability. The iTRAQ results presented here demonstrated that the survival of hepatic cells is compromised in animals living at polluted sites, which showed deep alterations in metabolism and the signalling pathways. The identified proteins may be useful as biomarkers of environmental pollution and provide insight about the metabolic pathways and/or physiological processes affected by pollutants in DNP and its surrounding areas. - Highlights: • iTRAQ quantitation was used for the first time to monitor a wildlife reserve • Over 2,000 proteins with altered expression were identified in problem Doñana sites • Of them, 118 changed over 2.5-fold in, at least, two problem sites • Upregulation of protective proteins

    The last ice age of Fennoscandinavia continues to have geological repercussions across Finland despite the last ice having retreated almost 10,000 years ago: land uplift, shoreline retreat, and the stress state of the crust continues to evolve. This report focusses on the glacial rebound signals for Finland and the Gulf of Bothnia and explores the consequences of the ongoing deformation. The rebound signals include the geological evidence as well as instrumental observations: the tide gauge and lake-level measurements of the past century, the changes in geodetic levels recorded in the repeat levelling surveys of the region and the direct measurement of crustal deformation (radial and horizontal) using high-precision space-geodesy measurements. These signals provide constraints on the Earth's rheology, its elasticity and viscosity, and the glacial history of the region. Once observationally constrained, the rebound models are used to predict both the ongoing evolution of shorelines and the changing state of stress within the crust. This report covers: (i) A review of glacial rebound modelling for Scandinavia (Sections 2 and 3). (ii) Review of observational evidence relating to sea-level change and crustal rebound (Section 4). (iii) New earth and ice-sheet model results from the inversion of the geological evidence for sea-level change, including models of shoreline evolution (Sections 5 and 6). (iv) Earth-model results from the inversion of the geodetic evidence for sea-level change (Section 7). (v) Development of crustal stress models for past and present stress states (Section 8). (vi) Conclusions and recommendations (Section 9). Specific conclusions reached pertain to: (i) Thickness of ice cover over Scandinavia since the Last Glacial Maximum, particularly for the Lateglacial period. (ii) Sea-level change and shoreline evolution for the Baltic area since the time the region became ice-free for the last time. (iii) The predicted rates of present-day crustal

    Repola, J.

    2013-06-01

    Biomass equations for above- and below-ground tree components of Scots pine (Pinus sylvestris L), Norway spruce (Picea abies [L.] Karst) and birch (Betula pendula Roth and Betula pubescens Ehrh.) were compiled using empirical material from a total of 102 stands. These stands (44 Scots pine, 34 Norway spruce and 24 birch stands) were located mainly on mineral soil sites representing a large part of Finland. The biomass models were based on data measured from 1648 sample trees, comprising 908 pine, 613 spruce and 127 birch trees. Biomass equations were derived for the total above-ground biomass and for the individual tree components: stem wood, stem bark, living and dead branches, needles, stump, and roots, as dependent variables. Three multivariate models with different numbers of independent variables for above-ground biomass and one for below-ground biomass were constructed. Variables that are normally measured in forest inventories were used as independent variables. The simplest model formulations, multivariate models (1) were mainly based on tree diameter and height as independent variables. In more elaborated multivariate models, (2) and (3), additional commonly measured tree variables such as age, crown length, bark thickness and radial growth rate were added. Tree biomass modelling includes consecutive phases, which cause unreliability in the prediction of biomass. First, biomasses of sample trees should be determined reliably to decrease the statistical errors caused by sub-sampling. In this study, methods to improve the accuracy of stem biomass estimates of the sample trees were developed. In addition, the reliability of the method applied to estimate sample-tree crown biomass was tested, and no systematic error was detected. Second, the whole information content of data should be utilized in order to achieve reliable parameter estimates and applicable and flexible model structure. In the modelling approach, the basic assumption was that the biomasses of

    Otorhinolaryngology (ORL) is considered a specialty associated with few serious patient injuries. Research data that support this belief are, however, scarce. We analyzed claims associated with ORL to determine the number of Finnish cases and the possible common denominators. Register study of ORL cases in the Patient Insurance Centre (PIC), the Regional State Administrative Agencies (RSAA), and the National Supervisory Authority for Welfare and Care (Valvira) during the years 2004 to 2008. These three agencies are the main actors in the field of patient injury in Finland. We analyzed compensated ORL patient injury cases from the PIC and cases associated with the ORL specialty for Valvira and RSAA from 2004 to 2008 and surveyed patient treatment files, statements from specialists, and compensation decisions. Injuries were usually associated with operations; three patients who experienced injuries during these procedures died. Common ORL operations such as tonsillectomy, septoplasty, and paranasal sinus surgery were most often associated with compensated injuries. Serious injuries were few, with a total of 110 out of 422 (26.1%) claims compensated by the PIC. Of the 110 compensated cases, 30 (27.3%) were related to tumor surgery. The most usual compensated case had iatrogenic nerve injury affecting the facial or trigeminal nerves. Of the compensated cases, 79 (71.8%) were treated by specialists, 15 (13.6%) by residents, and the rest by other medical professionals. Patient injuries in ORL are seldom severe and are strongly associated with surgery. A typical compensated injury was one that occurred in a central hospital during working hours. N/A.

  4. The Fourth Way in Finland

    Full Text Available This article focuses on the general history of the Fourth Way in Finland. The Fourth Way, or simply ‘the Work’, began as a Greco-Armenian man named Georges Ivanovich Gurdjieff (1866?–1949 gathered groups of pupils in St Petersburg and Moscow in 1912. To these groups, Gurdjieff started to teach what he had learned and synthesized between ca 1896 and 1912 during his travels on spiritual search of Egypt, Crete, Sumeria, Assyria, the Holy Land, Mecca, Ethiopia, Sudan, India, Afghanistan, the northern valleys of Siberia, and Tibet. Neither Gurdjieff nor any of his disciples called themselves a church, a sect, or anything alike, but referred to themselves simply as ‘the Work’, or as ‘the Fourth Way’. The name ‘the Fourth Way’ originates in a Gurdjieffian view that there are essentially three traditional ways of spiritual work: those of a monk, a fakir, and a yogi. These ways do not literally refer to the activities of a monk, a fakir, and a yogi, but to similar types of spiritual work emphasizing exercise of emotion, body, or mind. Gurdjieff’s teaching is a blend of various influences that include Suf­ism, orthodox Christianity, Buddhism, Kabbalah, and general elem­ents of various occult teachings of both the East and the West. Gurdjieff’s teaching is a blend of various influences that include Suf­ism, orthodox Christianity, Buddhism, Kabbalah, and general elem­ents of various occult teachings of both the East and the West. It is a unique combination of cosmology, psychology, theory of evolution, and overall theory and practise aiming to help individ­uals in their efforts towards what is called ‘self-remembering’.

  5. Additive Manufacturing in Finland: Recommendations for a Renewed Innovation Policy

    Ituarte, Iñigo Flores; Salmi, Mika; Ballardini, Rosa Maria; Tuomi, Jukka; Partanen, Jouni

    The objective of this research is to define an optimal innovation policy and funding strategy to improve Additive Manufacturing (AM) capabilities in Finnish companies. To do so, we present an international review of innovation programs in the area of AM. In addition, the study replied upon a survey prepared to evaluate factors for AM implementation. The ultimate goal is to help in the definition of a national policy strategy in the area of AM based on the characteristics of the Finnish industrial ecosystem. The methodology and data collection method involved defining the taxonomy of Finnish AM industry. The target group of the survey was a population of AM experts, and individuals with knowledge on AM and industrial processes. Overall, the survey revealed that research and innovation activities are well positioned in Finland. In order for future innovation policies to further support developments in the field, we estimated that policy strategies need to generate about 6-8 M€/year in national and EU- funding instruments for AM technology transfer, development, and innovation activities. Efforts should be targeted towards strengthening uses of AM in final production. In fact, only 36% of Finnish respondents declared to use AM for final production, while leading countries in AM use it in average more than 50%. Another area in need of development in Finland is the use of AM high performance materials. Moreover, outsourcing of AM services in Finland is 23 percentage point higher in national and 13 percentage point higher in international outsourcing to service bureaus and suppliers. In this regard, future policies and funding strategies should maintain the created momentum. However, there is a need to acquire high-end research and industrial equipment to stimulate AM integration to the existing production systems. This in the end can trigger the creation of new products, processes and intellectual property, enabling innovation and competitive advantage.

  6. Fine-Scale Genetic Structure in Finland

    Full Text Available Coupling dense genotype data with new computational methods offers unprecedented opportunities for individual-level ancestry estimation once geographically precisely defined reference data sets become available. We study such a reference data set for Finland containing 2376 such individuals from the FINRISK Study survey of 1997 both of whose parents were born close to each other. This sampling strategy focuses on the population structure present in Finland before the 1950s. By using the recent haplotype-based methods ChromoPainter (CP and FineSTRUCTURE (FS we reveal a highly geographically clustered genetic structure in Finland and report its connections to the settlement history as well as to the current dialectal regions of the Finnish language. The main genetic division within Finland shows striking concordance with the 1323 borderline of the treaty of Nöteborg. In general, we detect genetic substructure throughout the country, which reflects stronger regional genetic differences in Finland compared to, for example, the UK, which in a similar analysis was dominated by a single unstructured population. We expect that similar population genetic reference data sets will become available for many more populations in the near future with important applications, for example, in forensic genetics and in genetic association studies. With this in mind, we report those extensions of the CP + FS approach that we found most useful in our analyses of the Finnish data.

  7. Geological site selection studies in Precambrian crystalline rocks in Finland

    1988-01-01

    In general geological investigations made since 1977 the Finnish crystalline bedrock has been determined to be suitable for the final disposal of the spent nuclear fuel. Regional investigations have been mainly based on already existing geological studies. Special attention has been paid on the international geological Finland as the Baltic Shield is stiff and stable and situated far outside the zones of volcanic and seismic activity. The present day crustal movements in Finland are related to landuplift process. Movements and possible faults in the bedrock follow fracture zones which devide the bedrock into mosaiclike blocks. As compared to small scale geological maps the bedrock blocks are often indicated as large granite rock formations which are less broken than the surrounding rocks, though the age of granite formations is at least 1500 millions of years. The large bedrock blocks (20-300 km 2 ) are divided to smaller units by different magnitudes of fractures and these smaller bedrock units (5-20 km 2 ) have been selected for further site selection investigations. At the first stage of investigations 327 suitable regional bedrock blocks have been identified on the basis of Landsat-1 winter and summer mosaics of Finland. After two years of investigations 134 investigation areas were selected inside 61 bedrock blocks and classified to four priority classes, the three first of which were redommended for further investigations. Geological criteries used in classification indicated clear differences between the classes one and three, however all classified areas are situated in large rather homogenous bedrock blocks and more exact three dimensional suitability errors may not be observed until deep bore holes have been made

    Fossil fuel subsidies and other state support for fossil fuels are forbidden by the Kyoto Protocol and other international treaties. However, they are still commonly used. This publication presents and analyses diverse state support mechanisms for fossil fuels in Finland in 2003-2010. Total of 38 support mechanisms are covered in quantitative analysis and some other mechanisms are mentioned qualitatively only. For some mechanisms the study includes a longer historical perspective. This is the case for tax subsidies for crude oil based traffic fuels that have been maintained in Finland since 1965.

    In Finland the level of energy consumption for heating, transportation and industry is higher than in many other European countries. This is due to the northern position of the country and also to the fact that Finland is sparsely inhabited. Peat is one of the Finnish domestic energy resources. This brochure provides a compact package of background information on fuel peat. All the data presented concerning the production and use of peat, employment, investments in the peat industry, emission levels resulting from the production and use of peat, new combustion technologies and peatland resources, have been collected from documents and other sources that are accessible to the general public

    Hillerdal, G.

    1983-07-01

    In the county of Uppsala, Sweden, all detected cases of pleural plaques have been investigated with reference to asbestos exposure. Up to June, 1981, the number of men found to have pleural plaques were 1030 and the number of women 42. A disproportionately high percentage, especially of the women and the younger men, were born in Finland. Also, the Finnish-born had been exposed to asbestos to a significantly lower degree. They came from all parts of Finland - not only from the area where anthophyllite asbestos is found and where endemic plaques are common. Thus, some other factor must have caused these plaques among the Finns.

  13. Structural and K/Ar Illite geochronological constraints on the brittle deformation history of the Olkiluoto Region, Southwest Finland

    Viola, G.; Zwingmann, H.; Todd, A.; Raven, M.

    2011-07-01

    This study has generated a new conceptual scheme for the > 1.5 Gyr long brittle evolution of southwestern Finland and the Olkiluoto Island. Based on the study of a number of chosen outcrops containing key structural relationships and the analysis of almost two thousands striated fault planes, seven robust paleo stress tensors have been defined. By comparing and contrasting them with known paleostates of stress derived from southeast Sweden and by using absolute and relative geochronological criteria, it was possible to assign them to a number of specific tectonic events that have affected southwest Finland. Uniaxial compression of late Svecofennian age with a regional NNWSSE σ 1 axis was active soon after 1.75 Ga ago, when environmental conditions leading to brittle deformation were first attained in the region. A younger paleostress field with a NE-SW σ 1 axis, transpressive in character, is inferred to have been active soon after and to have caused significant reactivation of some of the structures formed during the first shortening event. A phase of ESE-WNW extension is constrained by a number of stress tensors and direct field evidence and is here tentatively assigned to the Gothian event and the time of rapakivi magmatism. Further NE-SW extension is taken as the last increment of crustal extension in southwestern Finland and is interpreted as having accommodated upper crustal stretching and the formation and infill of the NWSE- elongated Satakunta graben between 1.6 and 1.3 Ga. A significant and wellconstrained phase of c. NE-SW shortening post dated the rapakivi granites as well as the abundant c. 1260 Ma olivine diabase sills in southwestern Finland. A shortening direction of similar age is not described elsewhere in Fennoscandia. We propose that this phase might be the expression of an hitherto unreported phase of compression that caused inversion of the Satakunta graben. Later E-W compression is assigned to the early stages of the Mesoproterozoic

    Full Text Available Finland aims to be a carbon-neutral society by the year 2050. We are interested to know on a general level how sustainable living materializes among Finnish people, what is the structure of a sustainable lifestyle in Finland and how do people reason about their everyday behavior choices in the context of sustainability in order to combat climate change. The data (n = 2052 were collected by questionnaire in April 2017. They were corrected by sex, age and residential area to be representative of the population of Finland (18–79 years old. We applied mixed methods. A principal axis factoring was conducted on the 32 variables with orthogonal rotation (varimax. Six factors explained 65.2% of the variance. The respondents were also able to write why they considered the specific variable to be important for them. We classified 2811 reasonings. According to our results, Finns have become conscious of climate change, but carbon reduction has not become mainstream in their everyday life. Circulation and preventing loss of materials show a promising start to a Finn’s sustainable way of living. Recycling has been automated so that it is part of a Finn’s everyday routine and habits. Finns also favor domestic food and products. They are interested in the origin of materials. Essential reasons for that are supporting the local economy and ensuring a good employment rate for the state. Smart, carbon-free mobility is a challenge. Finns seem to estimate that their personal car use is already at the proper level. On the other hand, even one fifth reported consideration of environmental effects when planning holidays.

  18. Colloids or artefacts? A TVO/SKB cooperation project in Olkiluoto, Finland

    Laaksoharju, M.; Vuorinen, U.; Snellman, M.; Helenius, J.; Allard, B.; Pettersson, C.; Hinkkanen, H.

    1993-12-01

    TVO (Teollisuuden Voima Oy, Finland) initiated a co-operative task with SKB (Swedish Nuclear Fuel and Waste Management Co.) to critically evaluate colloid sampling methods at the test site in Olkiluoto, SW Finland. Three different colloid sampling methods were compared when sampling borehole OL-KR1 at 613-618 m depth. One possible way to make a conservative in-situ colloid estimation is to omit the contribution from calcite precipitation which is considered to be the main artefact. When this is made the inorganic colloid content (size 1-1000 nm) in Olkiluoto is 184 ±177 ppb consisting of clay minerals, silica, pyrite, goethite and magnesium oxide; the concentration of organic substances are around 100 ppb. The in-situ colloid concentration seems to be low which is in good agreement with experiences from years of sampling in similar environment and depths. The exercise shows the many difficulties encountered when sampling colloids. Small error in the planning, pump rate selection, a lack of precautionary measures, artefact sensitivity of the method etc have a tendency to affect significantly the results on the measured ppb colliod level

    1989-07-01

    Results from a survey of environmental gamma radiation levels in Finland after the Chernobyl accident 1986 are presented. The measurements were made in 1986-87 by means of sensitive Geiger-counters and a gamma-spectrometer placed in cars. The results show the level of external radiation caused by the cesium fallout on the first of October 1987. The fallout pattern of 137 Cs as well as of 95 Zr and 103 Ru are also presented. In the center of Southern Finland there are wide areas with exposure levels exceeding 0.03 μSv h -1 , areas exceeding 0.10 μSv h -1 being very rare. The surface area weighted mean dose rate for the 461 municipalities in Finland was 0.027 μSv h -1 (range 0-0.19 μSv h -1 ). The population weighted mean dose rate was 0.037 μSv h -1 . The corresponding estimated surface activity of 137 Cs was 10.7 kBq m -2 . The passage of the Chernobyl plume over Finland in 1986 led to various fallout patterns for different radionuclides. The deposition of the non-volatile nuclides, 95 Zr and 141 Ce, is closely related to the passage of the hot particle dust formed at the initial explosion in the reactor at 01.23 LT on 26 April. This cloud passed over Finland between the morning and the night of 27 April. The deposition of volatile fission products such as 131 I, 132 Te, 134 Cs and 137 Cs in Finland was caused by releases from the burning reactor after the initial explosion. The radioactive plume spread over Southern and Central Finland between Sunday 27 April and Tuesday 29 April. On 30 April and finally on 1 May a could northerly airstream spread into the whole of Finland purifying the atmosphere. The volatile nuclides were mainly deposited by intermittent rain on 28-30 April. The deposition pattern of 103 Ru is a combination of the fallou patterns due to the initial explosion and the reactor burn, as well as the wet deposition occurring on 10-12 May caused by the releases from the burning reactor in early May

    2014-07-01

    The concentrations of radioactive substances in the environment and foodstuffs are continuously monitored in Finland. Radiation and Nuclear Safety Authority (STUK) publishes the annual report of Surveillance of Environmental Radiation which shows the activity levels of artificial radionuclides in Finland. Based on the results the radiation dose to Finnish people is estimated. Natural radioactive elements will be included in the surveillance program in future years. The aim of the foodstuffs monitoring program is to obtain information from the intake of radionuclides through ingestion. The radioactivity in foodstuffs is monitored by collecting foodstuffs on market, drinking water and daily meals offered at hospitals over one week. The sampling sites are located in southern, central and northern Finland, representing the main population centres and areal differences in the consumption of foodstuffs. One of these sampling sites is located in the highest {sup 137}Cs deposition area in Finland originating from the Chernobyl accident. The foodstuff samples on market are, for example, wild game, wild berries, wild mushrooms and fish. {sup 137}Cs and {sup 90}Sr are analysed from mixed diet samples and {sup 137}Cs from foodstuffs samples on market. The concentrations of {sup 137}Cs and {sup 90}Sr in daily meals are low because the agricultural products used as raw material are almost free of artificial radionuclides. The small variation in the results is caused by the differences in the types of meals that were prepared on the sampling dates and in the areal origins of raw materials. {sup 137}Cs concentration is remarkably higher in such food which contains a lot of natural products like wild berries, freshwater fish, wild mushrooms and game. As an example, the concentrations of {sup 137}Cs in the solid food in 2012 ranged from 0.06 - 1.0 Bq/kg, and in the drinks from 0.27 - 0.40 Bq/l, respectively. The radiation dose to Finnish people is estimated based on an analysis of

  2. U-Th-Pb zircon geochronology on igneous rocks in the Toija and Salittu Formations, Orijärvi area, southwestern Finland: constraints on the age of volcanism and metamorphism

    Full Text Available Zircons from a felsic volcanic rock in the Toija Formation and a synvolcanic gabbro intrusion in the Salittu Formation within the Orijärvi area were dated by U-Th-Pb SIMS in order to provide depositional constraints on these formations. Zircon crystals from the felsic rock preserve a two-stage crystallisation history with zoned core domains and homogeneous rim domains. Inner domains yield a 1878±4 Ma concordia age, interpreted to determine the crystallisation of this rock. Rims yield a 1815±3 Ma concordia age interpretedto determine the regional metamorphism. Small rounded zircon grains from the Salittu gabbro, located within the Jyly shear zone, yield a concordia age of 1792±5 Ma. We interpret the grain textures to suggest that they recrystallised from inherited zircon seeds during the heat and fluid flow into the shear zone. Although no direct ages for the Salittu Formation have been recovered, field relationships imply that it was deposited between 1878−1875 Ma.

    Up to the present time scientists researching the causes of the vast areas of forest damages observed in Europe and North America have presented many different hypotheses. Among the first explanations was the damaging effect of acid rain. Some researchers claimed that of all air pollutants ozone was the most important damaging agent. The stress theory emphasizes the interaction of nitrogen oxides and sulphur dioxide with oxidants, hydrocarbons and heavy metals to be the main cause of toxic effects. In addition to above-mentioned theories, projects carried out by the Finnish Meteorological Institute (FMI) have revealed that under northern conditions coniferous forests have been damaged even in situations where the emissions consist of sulphur and nitrogen compounds occurring together. This theory postulates that the interaction of the above pollutants may be responsible by themselves for the effects on coniferous forests. The interaction is supposed to cause damages by two different mechanisms, namely, by causing direct toxic effects or through wintering failures. These mechanisms are indicated by the total nitrogen and sulphur concentration relationships of the needles. In the first case both sulphur dioxide and nitrogen oxides occur at such a high levels in the air that they cause direct damages, while in the second case sulphur dioxide concentration, in particular, is lower and both compounds can then be used as nutrients causing nutrient imbalance and a loss of wintering hardiness of the needles. The study area in these projects was southeastern Finland, which is one of the most polluted areas in our country. Domestic emissions from the paper and pulp industry, as well as the Russian emissions (e g. from the Leningrad region) affect this area. The aim of this study was to test the sulphur-nitrogen hypothesis using data collected from the Kymi province, S.E. Finland. (author)

    This paper presents the business models of small-scale heat energy production in Finland. Firstly, the development of heat entrepreneurship in the country is presented, including the remarkable growth of small and medium size enterprises (SMEs) in the last 15 years. Secondly, the concept of business model (business architecture of product/service flows and earning logics) is modified to the framework of wood heat production. The business model concept, and its sub-concepts, is applied in a brief review of current heat energy businesses in Finland. We arrive at a business model of heat entrepreneurships that are public companies/utilities, public-private partnerships, private companies and cooperatives, Energy Saving Company (ESCO), network model of large enterprise and franchising. Descriptive cases of these models are presented. Finally, the paper concludes with a discussion on the applicability of the business models in different operational environments and geographical contexts. (author)

    1993-01-01

    The use of wood biomass in Finland to generate energy (4.3 Mtoe) is one of the largest in the western industrialized countries. It represents 14 % of the primary energy use, while the use of peat for energy generation (1.4 Mtoe), often included in the same group, makes up 4-5 %. Significant energy groups include bark and sawdust (0.95 Mtoe) and waste liquors (2.4 Mtoe) from the chemical forest industry. Peat has primarily been used in population centres and by industry for combined generation of heat and power. The utilization of own by-products and other back-pressure generation based on peat or on imported fuels (in southern Finland), is typical for the industrial power plants. Wood biomass utilization will also be competitive in the future if it is readily collected in sufficient quantities at a given place as waste wood for industry. These biomasses include bark, various sawdusts, industrial waste chips and screenings, and as a separate group black liquor in the process circulation of the wood processing industry. The development of fluidized bed boilers in particular has provided improvement prerequisites for the use of low grade fuel batches of varying quality in combined heat and power plants. Most of the combined heat and power plants now built in Finland exceed the limit set for the competitiveness. Consequently, the prospects for an economical increase of combined heat and power generation capacity in Finland based on present technology is relatively small. The size of a competitive power plant has been determined to be about 50 MWe

    Remote Handling is very important technology in the ITER project. Even ITER is regarded as a fairly long project, for the remote handling methods, tools and systems there is not very much development time provided. The technology has to be developed and demonstrated a long before supplied to the site in Cadarache. This is a large challenge, because the complex operations and extremely high reliability requirements. In the end of 2004, the Remote Operation and Virtual Reality Centre (ROViR) was established in Tampere Finland. The start up for this facility creation was an agreement with EFDA to host the Divertor Test Platform 2 (DTP2) in Finland. During the year 2005 the ROViR Centre was put in action. The construction work for DTP2 is currently going on and the platform should be ready for hosting the remote handling development by the end of 2006. After that the laboratory will receive the robots, tools and employees for the DTP2 operation. This abstract will give an overview of the DTP 2 platform in Tampere Finland as well as describe some other projects started in 2005. Presentation describes some problems of the ITER remote handling and tells about the state-of-the-art solutions. It also highlights some of the next tasks after putting the DTP2 platform in action. There are a plenty of tasks in the development of the ITER remote handling, after DTP2 laboratory is established. (author)

    Abstract. This work aimed to study the floral biology and the pollination’s ecology of Canavalia rosea (Sw. DC. (Leguminosae-Papilionoideae by bees in the sandbank vegetation of the Grumari Environmental Protection Area (EPA , located in the western zone of Rio de Janeiro’s city. The study was developed between the months of June of 2008 to June of 2009. Sampling on morphology, color and odor of the flowers of the species were made. The number of open flowers per day in each individual was recorded, as well as the opening steps, determining the period of anthesis. The occurrence of floral visitors was recorded through the observation of the visit’s time, of the adaptability for pollination, of the ease of access to the reward and of the intra-floral behavior played. C. rosea occurs in psamophily communities and in post-beach sandbank of Grumari’s EPA. It presents typical characteristics of mellitophily (pollination by bees and the flowers are pollinated by Xylocopa frontalis Oliver. It also receives visits from Tetragonisca angustula Latreille, Trigona spinipes Fabricius and Apis mellifera Linnaeus, which collects pollen without pollinating the flowers. X. frontalis proved to be the only effective pollinator of C. rosea in the Grumari sandbank, making the plant directly dependent on this species for fruit and seed’s production in this location.

    Full Text Available In this study, analysis results reveal two main deposition zones are located at the flank of upper Gaoping Submarine Canyon and Lower Fangliao Basin offshore SW Taiwan. The non-event related sediments deposited in past 150 years (i.e., 632 Mt km-2 was delivered and transported from Gaoping River by suspension process with tides and coastal currents and gradually spread out offshore. Meanwhile, the total mass of accumulation sediments is 1922 Mt km-2, accounting for 40% Gaoping River’s sediment load and suggesting that the deposition process is mainly controlled by natural hazards. Sedimentation rates in much of the study area, except in the main deposition zones, are less than 0.5 cm yr-1 (5 m kyr-1. Compared with the studies at the instability seafloor caused by high sedimentation rates (~30 m kyr-1, the offshore southwestern Taiwan is relatively stable. In this study, we also discovered a series of sediment waves located on the upper continental slope between Gaoping and Fangliao Submarine Canyons, which is related to the creeping process on seafloor. In summary, our results reveal the fluid activities, existence of weak layers and earthquake triggering are potential factors which might induced seafloor failures offshore southwestern Taiwan.

    Fennovoima will build a nuclear power plant of 1200 MW at Hanhikivi headland in Pyhaejoki, Northern Finland on the shore of the Baltic Sea. According to the target schedule the plant will produce electricity in 2024. The plant supplier is Rusatom Overseas, subsidiary of the Russian Rosatom. No industrial activity is practiced in the immediate surroundings of the site area and the headland and its surroundings are sparsely populated. The area is in its natural state. This means that all the preparatory and infrastructure works needs to be done before the construction of NPP can start. The environmental and nature conservation aspects have to be taken into consideration in planning, construction and operation of the NPP. Northern location sets some challenges to the design of the power plant. The sea area is normally covered with ice almost half of the year which has to be taken into account in the design of the power plant. But there are also advantages: in winter when the cooling water is cold the efficiency of electricity production is estimated to be exceptionally good, approximately 39 %. Since 2008, Fennovoima has carried out several environmental studies and surveys in the site area and has collected information about the nature conditions on land and in the sea area. The collected environmental data has been utilized in land use planning, environmental impact assessment procedure and in applying for conventional permits. The environmental data can also be used as baseline data. The document is composed of an abstract and the presentation slides

    ExternE National Implementation is a continuation of the ExternE Project, funded in part by the European Commission's Joule III Programme. This study is the result of the ExternE National Implementation Project for Finland. Three fuel cycles were selected for the Finnish study: coal, peat and wood-derived biomass, which together are responsible for about 40% of total electricity generation in Finland and about 75% of the non-nuclear fuel based generation. The estimated external costs or damages were dominated by the global warming (GW) impacts in the coal and peat fuel cycles, but knowledge of the true GW impacts is still uncertain. From among other impacts that were valued in monetary terms the human health damages due to airborne emissions dominated in all the three fuel cycles. Monetary valuation for ecosystem impacts is not possible using the ExternE methodology at present. The Meri-Pori power station representing the coal fuel cycle is one of the world's cleanest and most efficient coal-fired power plants with a condensing turbine. The coal is imported mainly from Poland. The estimated health damages were about 4 mECU/kWh, crop damages an order of magnitude lower and damages caused to building materials two orders of magnitude lower. The power stations of the peat and biomass fuel cycles are of CHP type, generating electricity and heat for the district heating systems of two cities. Their fuels are of domestic origin. The estimated health damages allocated to electricity generation were about 5 and 6 mECU/kWh, respectively. The estimates were case-specific and thus an generalisation of the results to the whole electricity generation in Finland is unrealistic. Despite the uncertainties and limitations of the methodology, it is a promising tool in the comparison of similar kinds of fuel cycles, new power plants and pollution abatement technologies and different plant locations with each other.

    1997-12-01

    The purpose of this paper was to describe the transition of sterilization in Finland from an eugenic tool to a contraceptive. Historical data were drawn from earlier reports in Finnish. Numbers of and reasons for sterilizations since 1950 were collected from nationwide sterilization statistics. Prevalence, characteristics of sterilized women, and women's satisfaction with sterilizations were studied from a 1994 nationwide survey (74% response rate). Logistic regression was used for adjustments. In the first half of the 20th century, eugenic ideology had influence in Finland as in other parts of Europe, and the 1935 and 1950 sterilization laws had an eugenic spirit. Regardless of this, the numbers of eugenic sterilizations remained low, and in practice, family planning was the main reason for sterilization. Nonetheless, prior to 1970 not all sterilizations were freely chosen, because sterilizations were sometimes used as a precondition for abortion. Female sterilizations showed remarkable fluctuation over time. Male sterilizations have been rare. The reasons stipulated by the law did not explain the numbers of sterilizations. In a 1994 survey, 9% of Finnish women reported they were using sterilization as their current contraceptive method (n = 189). Compared to women using other contraceptive methods, sterilized women were older, had had more births and pregnancies, and came from lower social classes. Sterilized women were satisfied with their sterilization, but there were women (8.5%) who regretted it. In conclusion, sterilizations have been and are likely to continue to be an important family planning method in Finland. The extreme gender ratio suggests a need for promoting male sterilizations, and women's expressed regrets suggest consideration of a higher age limit.

  5. Sea urchins, their predators and prey in SW Portugal

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Sea urchins play a key role structuring benthic communities of rocky shores through an intense herbivory. The most abundant sea urchin species on shallow rocky subtidal habitats of the SW coast of Portugal is Paracentrotus lividus (Echinodermata: Echinoidea. It is considered a key species in various locations throughout its geographical distribution by affecting the structure of macroalgae communities and may cause the abrupt transformation of habitats dominated by foliose algae to habitats dominated by encrusting algae - the urchin barrens. The removal of P. lividus predators by recreational and commercial fishing is considered a major cause of this phenomenon by affecting the trophic relationships between predators, sea urchins and algae communities. Marine protected areas (MPAs usually lead to the recovery of important predator species that control sea urchin populations and restore habitats dominated by foliose macroalgae. Therefore, MPAs provide a good opportunity to test cascading effects and indirect impacts of fishing at the ecosystem level. The ecological role of P. lividus was studied on rocky subtidal habitats of the SW coast of Portugal (Alentejo considering three trophic levels: population of P. lividus, their predators (fish and shellfish and their prey (macroalgae communities. Several studies were conducted: (1 a non-destructive observational study on the abundance and distribution patterns of P. lividus, their predators and preys, comparing areas with different protection; (2 a manipulative in situ study with cages to assess the role of P. lividus as an herbivore and the influence of predation; (3 a descriptive study of P. lividus predators based on underwater filming; (4 and a study of human perception on these trophic relationships and other issues on sea urchin ecology and fishery, based on surveys made to fishermen and divers. Subtidal studies were performed with SCUBA diving at 3-12 m deep. Results indicate that in the

    Due to the complicated geomorphology and geological conditions, the southwest (SW) Taiwan suffers the invasion of various natural disasters, such as landslide, mud flow and especially the threat of strong earthquakes as result of convergence between the Eurasian and the Philippine Sea plate. Several disastrous earthquakes had occurred in this area and often caused serious hazards. Therefore, it is fundamentally important to understand the correlation between seismic activity and seismogenic structures in SW Taiwan. Previous studies have indicated that before the failure of rock strength, the behaviors of micro-earthquakes can provide essential clues to help investigating the process of rock deformation. Thus, monitoring the activity of micro-earthquakes plays an important role in studying fault rupture or crustal deformation before the occurrence of a large earthquake. Because the time duration of micro-earthquakes activity can last for years, this phenomenon can be used to indicate the change of physical properties in the crust, such as crustal stress changes or fluid migration. The main purpose of this research is to perform a nonlinear waveform inversion to investigate source parameters of micro-earthquakes which include the non-double couple components owing to the shear rupture usually associated with complex morphology as well as tectonic fault systems. We applied a nonlinear waveform procedure to investigate local stress status and source parameters of micro-earthquakes that occurred in SW Taiwan. Previous studies has shown that microseismic fracture behaviors were controlled by the non-double components, which could lead to cracks generating and fluid migration, which can result in changing rock volume and produce partial compensation. Our results not only giving better understanding the seismogenic structures in the SW Taiwan, but also allowing us to detect variations of physical parameters caused by crack propagating in stratum. Thus, the derived source

    1987-06-01

    The Chernobyl accident raised the deposition levels of radioactive substances in Finland. Fish were affected by radioactive substances in watersheds. Extensive study of areal and temporal changes in the radioactivity of freshwater fish was started soon after the accident. The aim of the study was to obtain new data on a situation involving fresh deposition and to estimate the importance of freshwater fish as a source of radiocesium for consumers. Attenuation was also paid to various factors affecting the radioactivity of fish. Samples were taken from about 200 lakes. In all, about 600 samples were analysed gammaspectrometrically. A few samples were also analysed radiochemically for beta-emitting 89 Sr and 90 Sr. The samples contained about ten different species of fish. The highest concentrations of radiocesium in fish were found in the areas of highest radioactive deposition in Finland. In areas with the same level of 137 Cs deposition, concentrations in fish depended on the size of the lake: the smaller the area of the lake in which the fish were caught the higher the concentration. Of the fish species studied, perches had the highest concentrations of radiocesium. Intake estimations were based on the average concentrations, weighted for catches, in each drainage area and in the whole country, and on the average intake of 137 Cs via freshwater fish. In Finland, the average intake of 137 Cs via freshwater fish in May-December 1986 was about 1200 Bq. The values obtained for different drainage basins varied from about 160 to 3400 Bq

    Wind power production from grid connected wind turbines in Finland was 481 GWh in 2011. This corresponds to 0.6 % of Finland's electricity consumption. Installed wind capacity was 199 MW at the end of the year and the number of the operating turbines was 131. Two new turbines were installed in 2011 with the total power of 1.75 MW and no turbines were taken out of operation. The average size of all turbines in Finland was 1 519 kW at the end of 2011 (1519 kW at the end of 2010). The new climate and energy strategy has a target of 2 500 MW wind power in 2020. A market based feed-in system with a guaranteed price of 83.5 euro/MWh entered into force on 25 March 2011 in Finland. There will be an increased tariff of 105.3 euro/MWh until end of 2015 (max 3 years). The difference between the guaranteed price and spot price of electricity will be paid to the producers as a premium. Year 2010 had close to long term average wind resource. The weighted production index for the four sea areas was 98 %. Average capacity factor of standard wind turbines, which operated the whole year, was 24 % while the best turbine yielded 45 % capacity factor. Technical availability of the standard wind power plants was 88,5 % in 2011. This report contains production and availability figures of the grid connected wind turbines in Finland as well as component summary of failure statistics. There is an English list of figure and table captions and the yearly statistics table is as an appendix. (orig.)

    and's limited choice of energy sources makes nuclear power especially lly attractive and it is estimated that in 1985 14% of the energy consumed will be nuclear, which will then be the second most important source after oil (49%). Four power reactors, Loviisa 1 and 2 and TVO 1 and 2, are at present under construction. The first two are Russian PWRs, the latter two Asea-Atom BWRs. Loviisa 3 and 4 are planned but not yet ordered, and plans for a 1000 MWe plant to the West of Helsinki exist. The nuclear controversy in Finland has mainly been repetitions of the US and Swedish debates since 1970. However, local opposition to the project W. of Helsinki, based on the sociological effects of the inflow of Finnish speaking workers into a rural Swedish speaking district has become apparent. In the long term 13 major nuclear power plants are envisaged by the year 2000. Finland is party to the NPT and the IAEA safeguard system. (JIW)

    1991-01-01

    A nationwide study on artificial and natural radioactivity in household water has been under way in Finland since the 1960s. The occurrence of artificial radionuclides in the surface water of drainage basins has been monitored extensively. The proportion of household water derived from surface waters in Finland is currently 48 %, but its usage is decreasing whereas that of groundwater is increasing at an annual rate of 1 - 2 %. The natural radioactivity of household water has been studied in almost all of the waters distributed by public waterworks and in 5400 private ground water wells. The downward trend in 90 Sr, 137 Cs and 3 H concentrations in surface water continued from the middle 1960s until the Chernobyl accident. After the accident ten different radionuclides were detected in surface waters, but only 137 Cs made a minor contribution the radiation dose. The maximum effective dose via ingestion of water was about 0.001 mSv in 1986, and considerably lower in the following years

    One of the main objectives of the Finnish Research Programme on Climate Change (SILMU) has been to assess the possible impacts of future changes in climate due to the enhanced greenhouse effect on natural systems and human activities in Finland. In order to address this objective, it was first necessary to specify the types of climate changes to be expected in the Finnish region. Estimates of future climate are conventionally obtained using numerical models, which simulate the evolution of the future climate in response to radiative forcing due to changes in the composition of the atmosphere (i.e. of greenhouse gases and aerosols). However, there are large uncertainties in the model estimates because current knowledge and understanding of atmospheric processes remains incomplete. Since accurate predictions of climate change are not available, an alternative approach is to develop scenarios. These are plausible projections which reflect the best estimates to the future conditions but at the same time embrace the likely uncertainties attached to these estimates. In order to obtain expert opinion on the most appropriate methods of providing scenarios for SILMU, an International Workshop was organised in 1993. The recommendations of the Workshop formed the basis of the present project, initiated in 1994, to develop standard climatic scenarios for Finland

    The report is associated with a study programme on basic rocks, which has the aim to complement the preliminary site investigations on repository for TVO's (Teollisuuden Voima Oy) spent nuclear fuel. The report comprises a mining enterprise's view of the ore potential of basic plutonic rocks in Finland. The ores associated with basic plutonic rocks are globally known and constitute a significant share of the global mining industry. The ores comprise chromium, vanadium-titanium-iron, nickel-copper and platinum group element ores. The resources of the metals in question and their mining industry are examined globally. A review of the use of these metals in the industry is presented as well. General factors affecting the mining industry, such as metal prices, political conjunctures, transport facilities, environmental requirements and raw material sources for the Finnish smelters have been observed from the point of view of their future effect on exploration activity and industrial development in Finland. Information on ores and mineralizations associated with Finnish basic rocks have been compiled in the report. The file comprises 4 chromium occurrences, 8 vanadium-titanium-iron occurrences, 13 PGE occurrences and 38 nickel-copper occurrences

    Recent major improvements in our knowledge about seismicity, crustal structure, primary stress field and tectonics together with other extensive geophysical and geological investigations have provided a good basis for a review of the seismotectonic setting of Finland. Correlations have been found to be present for the seismicity in Finland with the seismotectonic zones inside the Baltic Shield and with the seismicity of the North Atlantic Ridge. The current stress field in the Fennoscandian Shield seems to be dominated by ridge push forces. This conclusion is based on earthquake focal mechanisms, in-situ stress measurements and geodetic information. The report discusses the possible block movements induced by future glaciation. Location of the seismotectonic zones, duration of the glaciation and the presence of locally anomalous shear stresses seem to relate to the distribution of the discovered post-glacial faults in Fennoscandia. Special attention is paid to local seismotectonics. Potential direct or indirect effects on underground openings are possible due to local earthquakes or the creep. The importance of slow deformation processes in the bedrock is emphasized. (orig.)

    Until 1995 the electrical statistics information has according to the law about electric utilities and facilities been collected and handled by the Electrical Inspectorate. In 1996 the work was done by the Finnish Electricity Association and it was commissioned by the Ministry of Trade and Industry. Since 1996 the collection and handling of the information is based on the Electricity Market Act. The information is mainly submitted by the producers and distributors of electricity and processed since 1997 in Adato Energia Oy owned jointly by Finnish Energy Industries Federation, Finnish District Heating Association and Finnish Electricity Association. This action is based on a mutual contract of the Statistics Finland, Adato Energia Oy, Finnish Energy Industries Federation and Finnish Electricity Association. The Electricity Statistics for Finland 1997 contains several summaries about the consumption and the production. There is also summaries about the networks, the effects of electricity, the capacities of electricity, the fuels used in production and the dwellings heated by electric power. Like before a list of names, addresses, persons and telephone numbers is available. Additionally a list comprising the power consumption in all Finnish communes and a glossary in three languages (Finnish, Swedish and English) are included

    2000-10-02

    This paper is part of the study of atmospheric emissions of heavy metals conducted by the Finnish Environment Institute in collaboration with the Technical Research Centre of Finland (VTT) under the umbrella of the Finnish Ministry of the Environment. The scope of our study is limited solely to anthropogenic mercury that is emitted directly to the atmosphere. This article addresses emission factors and trends of atmospheric mercury emissions during the 1990s and is based mainly on the database of the Finnish Environmental Administration. In addition, data based on the measurements taken by the VTT regarding emission factors have been used to estimate emissions of mercury from the incineration of waste. The study indicates that the total emission of mercury has decreased from 1140 kg in 1990 to 620 kg in 1997, while industrial and energy production have been on the increase simultaneously. The 45% emission reduction is due to improved gas cleaning equipment, process changes, automation, the installation of flue gas desulfurization process in coal-fired power plants and strict pollution control laws. In the past, some authors have estimated a higher mercury emission in Finland. In this study, it is also observed that there are no big changes in the quality of raw materials. Estimated emission factors can be of great help to management for estimating mercury emissions and also its risk assessment.

  8. Risk Assessment in Finland: Theory and Practice

    Full Text Available The Finnish risk assessment practice is based on the Occupational Safety and Health Act aiming to improve working conditions in order maintain the employees' work ability, and to prevent occupational accidents and diseases. In practice there are hundreds of risk assessment methods in use. A simple method is used in SME's and more complex risk evaluation methods in larger work places. Does the risk management function in the work places in Finland? According to our experience something more is needed. That is, understanding of common and company related benefits of risk management. The wider conclusion is that commitment for risk assessment in Finland is high enough. However, in those enterprises where OSH management was at an acceptable level or above it, there were also more varied and more successfully accomplished actions to remove or reduce the risks than in enterprises, where OSH management was in lower level. In risk assessment it is important to process active technical prevention and exact communication, increase work place attraction and increase job satisfaction and motivation. Investments in occupational safety and health are also good business. Low absenteeism due to illness or accidents increases directly the production results by improved quality and quantity of the product. In general Finnish studies have consistently shown that the return of an invested euro is three to seven-old. In national level, according to our calculations the savings could be even 20% of our gross national product.

    There is an increasing political pressure on the city planning to create more energy efficient city plans. Not only do the city plans have to enable and promote energy efficient solutions, but it also needs to be clearly assessed how energy efficient the plans are. City planners often have no or poor know how about energy efficiency and building technologies which makes it difficult for them to answer to this need without new guidelines and tools. An easy to use tool for the assessment of the energy efficiency of detailed city plans was developed. The aim of the tool is for city planners to easily be able to assess the energy efficiency of the proposed detailed city plan and to be able to compare the impacts of changes in the plan. The tool is designed to be used with no in-depth knowledge about energy or building technology. With a wide use of the tool many missed opportunities for improving energy efficiency can be avoided. It will provide better opportunities for sustainable solutions leading to less harmful environmental impact and reduced emissions. - Highlights: • We have created a tool for assessing energy efficiency of detailed city plans. • The energy source is the most important factor for efficiency of districts in Finland. • Five case districts in Finland were analyzed. • In this paper one residential district has in-depth sensitivity analyses done

    International Nuclear Information System (INIS)

    2003-01-01

    The U.N. World Summit on Environment and Development in Rio de Janeiro in June 1992 was the origin of the international framework for sustainable development. As a basis for joint, sustainable action by governments, organizations, industries, and the public, the participating countries signed the Rio Declaration on Environment and Development, and drafted the associated action program, Agenda 21. Sustainable development comprises these three determinant factors: - Economy. - Ecology. - Social aspects. This is where entrepreneurial responsibility for society comes in. If industries want to generate overall positive effects, they must be efficient, competitive, and profitable on a long-term basis. Power supply systems meeting the criteria of sustainable development must be reliable, economically viable, socially acceptable, and environmentally compatible. The power supply in Finland is meeting these sustainability requirements in many ways. Finland's electricity supply is decentralized, using a variety of energy sources. Electricity can be generated and made available at low cost. The Finnish power industry is an important employer and a major factor in the economy. Moreover, electricity is generated in advanced types of power plants. In this way, the structure of the Finnish power supply system incorporates important factors of sustainable development. (orig.)

  11. Assuring future competence in nuclear safety in Finland

    2004-01-01

    Full text: Background: Within last few years we have been faced the fact that ageing of experts in nuclear safety field cannot be ignored in Finland. A great number of all experts/specialists with special competence on nuclear safety studied in the early 70's and had their first permanent jobs in the 'golden era' of nuclear power. These experts are going to retire within next ten years. Therefore both the regulatory body and licensees in Finland have the situation where the age distribution of staff member has become distorted. Also the amount of students in universities which have nuclear technology as their major subject has diminished remarkably until the decision of the new nuclear power plant unit in Finland was made in May 2001. After that the amount of students has risen. Assuring competences within the regulatory body STUK adopted the systematic approach to training in early 90's, this method is widely presented in IAEA TECDOC 1254 (2001). However, the very low turnover of staff led to decrease of training needs and therefore also the systematic training efforts decreased. In 2001 a need to restart the systematic approach to assuring competences was identified. To improve competence management at the regulatory body a competence analysis was carried out and a human resource plan for nuclear safety area for the near future was made. Competence analysis is a method which is quite commonly used on public sector and governmental organisations in Finland. STUK studied carefully the models used in other public sector organisations and adjusted the method to its own purposes. The model used has four competence categories: substance related, management skills, common working skills and STUK related working skills. Substance related competences were defined and described at working unit level. Descriptions for the rest three categories were made at STUK level and those were common for all departments. Substance related competencies common to all working at the

    Full Text Available Background: The agreement of new instruments or clinical tests with other instruments or tests defines the possibility of these being used interchangeably. Aim: To investigate the validity and reliability of the SW-100 autokeratometer using a Bausch & Lomb (B&L keratometer as the ‘gold standard’. Methods: Eighty subjects (80 right eyes aged between 21 and 38 years were recruited. For intra-test repeatability, two measurements of the corneal radius of curvature were taken with the SW-100 and B&L keratometers. Forty of the 80 subjects participated in the inter-test repeatability measurement. Results: Corneal radius of curvature was found to be statistically different between the two instruments (p < 0.001, with the SW-100 providing slightly flatter values of 0.11 mm and 0.05 mm for the horizontal and vertical meridians, respectively, than the B&L keratometer. The average corneal curvature was 0.07 mm flatter with the SW-100 autokeratometer than with the B&L device. Agreement between the SW-100 and B&L keratometers’ axes was 45% within ± 5°, 60.3% within ± 10°, 78.8% within ± 15°, 80.3% within ± 20°, and 88.7% within ± 40°. Intertest repeatability was better for the B&L device than the SW-100 and showed no significant difference between the two sessions. Both instruments demonstrated comparable intrasession repeatability. As such, both instruments were comparatively reliable (per coefficients of repeatability. The range of limits of agreement of ± 0.14 mm (horizontal meridian and ± 0.17 mm (vertical meridian between the SW-100 and B&L devices showed good agreement. Conclusion: The results suggest that the SW-100 autokeratometer is a reliable and objective instrument that, however, provides flatter radii of curvature measurements than the B&L keratometer. A compensating factor incorporated into the instrument could reduce the difference between the two instruments and make them more interchangeable.

    The aim of the study was to inventorize the emissions and other stressors caused by fuel peat use in Finland. The life cycle approach was used to organise and compile the burdens associated with the fuel peat utilisation sector in the years 1994 and 1995. Fuel peat accounts for about 6.5 % of the total primary energy production in Finland. The study showed that most emissions out into the air occur during combustion of peat in energy plants. The emissions account for about 13 - 14 % of the CO 2 emissions released by fossil fuel utilisation in Finland, for 12 % of the SO 2 for 8 % of the N 2 O and approximately 4 % of the NOR emissions released by anthropogenic sources in Finland. Phosphorus releases into waters contributes for about 0.2 % while nitrogen releases account for 0.3 % in the total anthropogenic discharge in Finland. (orig.) 88 refs

    Full Text Available Background and Purpose: The concentrations of greenhouse gases in the atmosphere have been increasing over the last hundred years in relation to the Fourth IPCC assessment report that highlighted human activities as a direct influence on climate changes. Since Croatia and Finland signed the Kyoto Protocol, they are both committed to fulfil international obligations of lowering GHG’s emissions, enhancing the storage, as well as protecting and enhancing the current pools where the forestry sector has a prominent role. These obligations created a need for a review on carbon storage potentials for both countries with the aim of setting further scientific and management guidelines as the basic purpose of this research. Materials and Methods: Data collection was conducted within the scope of the Sort Term Scientific Mission (STSM in the period from May 2 – July 22, 2009 in the Finnish Forest Research Institute in Joensuu. The research encompassed an overview of literature, personal contacts with scientists and experts from both countries (research institutes, ministries, the EFI branch office in Joensuu and a field inspection which altogether provided an insight into the applied silvicultural and utilization activities. A significant data source were official documents and published project results on the carbon storage potential. Results and Discussion: Mitigation activities within the framework of the LULUCF project reduced the total emissions for 33.4 millions tons of CO2 equivalents in Finland in 2006 (this data has varied from 18 to 33.4 millions tons CO2 equivalents in the last fifteen years while for Croatia the availability of such data is limited. Finland has some former agricultural land which may be afforested but not in the substantial share, while in Croatia such areas amount to around 1 million ha. According to the climate change scenario for Finland (FINADAPT, predicting the largest climate changes, the total forest growth

    Full Text Available The Paleoproterozoic Misi region forms the northeastern part of the Peräpohja Schist Belt in northern Finland. The area comprises mafic volcanic and sedimentary rocks, differentiated gabbros, and late-orogenic granitoids. Three geochemically different mafic volcanic units were recognised: LREE-depleted amygdaloidal lavas, slightly LREE-enriched lavas, and mafic tuffs that have a flat REE pattern. Sedimentary rocks include arkosites, mica gneisses, dolomitic marbles, quartzites, tuffites, mica schists, calc-silicate rocks and graphite-bearing schists. Two types of gabbros wereidentified: one with a LREE-enriched pattern and another with flat REE pattern. The age of the former is according to Perttunen and Vaasjoki (2001 2117±4 Ma, whereas there is no age determination for the latter. The granitoid intrusions belong to the ca. 1800 Malate-orogenic group of the Central Lapland Granitoid Complex. The geochemistry and the stable isotope data on mafic lavas and dolomitic marbles show similarities with the mafic volcanic rocks and marbles of the lower part of the Kivalo group in the western part of Peräpohja Schist Belt. Peak metamorphic conditions in the region vary from upper-greenschist to upper-amphibolite facies. Three major stages of deformation were distinguished: N-S compressional D1 with ductile deformation, NE-SW compressional D2 with ductile to brittle-ductile deformation, and E-W compressional D3 with brittle deformation. Several magnetite occurrences are known in the region and four of those have been mined for iron. The ores are mainly composed of magnetite with minor haematite, pyrite, chalcopyrite and bornite. Besides iron, the ores contain small amounts of P, S and V aswell as trace amounts of Cu, Co, Te and Au. The magnetite bodies are hosted by skarnoids within the ca. 2220–2120 Ma dolomitic marble-quartzite sequence, and highly differentiated, intensely albitised, LREE-enriched gabbro. Multistage and -type alteration is

  1. Development of stump utilization in Finland

    Energy Technology Data Exchange (ETDEWEB)

    Karkkainen, M

    1975-01-01

    Presents a historical review of the utilization of stump- and rot-wood in Finland, based on Finnish literature from the mid 19th century until to-day. Pine stumps were used for tar production to a small extent during the 19th century, and on a much larger scale during the two World Wars. Other industrial uses of stumpwood have hitherto been of minor importance, but stumps are now beginning to be used in the pulp industry. The largest quantity of stumpwood used has always been that taken by the rural population for fuel; it amounted to >200 000 m/sup 3/ solid measure in the 1930's, and was still >100 000 m/sup 3/ in the 1960's.

    Coastal planning requires detailed knowledge of future flooding risks, and effective planning must consider both short-term sea level variations and the long-term trend. We calculate distributions that combine short- and long-term effects to provide estimates of flood probabilities in 2050 and 2100 on the Finnish coast in the Baltic Sea. Our distributions of short-term sea level variations are based on 46 years (1971-2016) of observations from the 13 Finnish tide gauges. The long-term scenarios of mean sea level combine postglacial land uplift, regionally adjusted scenarios of global sea level rise, and the effect of changes in the wind climate. The results predict that flooding risks will clearly increase by 2100 in the Gulf of Finland and the Bothnian Sea, while only a small increase or no change compared to present-day conditions is expected in the Bothnian Bay, where the land uplift is stronger.

    2018-03-01

    The aim of this work is to evaluate and describe the current status of, and prospects for, the future of occupational hygiene in Finland. The main sources of information include a seminar held in the annual meeting of Finnish Occupational Hygiene Society and interviews with different stakeholders. Nanotechnology and other new materials, changing work environments, circular economy including green jobs, new medical methods and advances of construction methods were recognized as future challenges. Future work opportunities for occupational hygiene experts included exposure assessments in indoor air surveys, private consulting and entrepreneurship in general, international activities and product safety issues. Unclear topics needing more attention in the future were thought to be in new exposures, sensitive persons, combined effects, skin exposures and applicability of personal protective equipment. Occupational hygiene should broaden its view; occupational hygienists should have to cooperate with other specialists and grasp new challenges.

    A survey on the use of radiopharmaceuticals in diagnostics and therapy has been made by STUK Radiation and Nuclear Safety Authority in Finland. In 1997 the number of nuclear medicine examinations was 51 700 and that of the therapeutic treatments was 2 240. In 1994 the number of nuclear medicine examinations was 50 900 and that of therapeutic treatments was 2 150. The collective effective dose to the patients was 207 manSv and the mean effective dose to the population was 0.04 mSv per person. In 1994 the collective effective dose was 220 manSv. The numbers of nuclear medicine examinations and of therapeutic treatments have not changed much when compared to those in 1994. The collective effective dose has decreased. The main reason for that is the decreased use of the radionuclide 131 I. (orig.)

    Retamal C, Pedro; Markkula, Niina; Peña, Sebastián

    2016-07-01

    This article analyses and compares the epidemiology of mental disorders and relevant public policies in Chile and Finland. In Chile, a specific mental health law is still lacking. While both countries highlight the role of primary care, Finland places more emphasis on participation and recovery of service users. Comprehensive mental health policies from Finland, such as a successful suicide prevention program, are presented. Both countries have similar prevalence of mental disorders, high alcohol consumption and high suicide rates. In Chile, the percentage of total disease burden due to psychiatric disorders is 13% and in Finland 14%. However, the resources to address these issues are very different. Finland spends 4.5% of its health budget on mental health, while in Chile the percentage is 2.2%. This results in differences in human resources and service provision. Finland has five times more psychiatric outpatient visits, four times more psychiatrists, triple antidepressant use and twice more clinical guidelines for different psychiatric conditions. In conclusion, both countries have similar challenges but differing realities. This may help to identify gaps and potential solutions for public health challenges in Chile. Finland’s experience demonstrates the importance of political will and long-term vision in the construction of mental health policies.

  7. The connection between migration and regional structure in Finland around 1990 - a GIS viewpoint

    Jarkko Kauppinen

    2000-01-01

    Full Text Available The connection between migration and regional structure in Finland in the early 19905 is discussed on the basis of Geographic Irformation Systems (GIS data from Statistics Finland, compiled for map coordinate grid cells of 1 x 1 km. The results indicate that data of this kind enable a more detailed typology to be drawn up for migration. At the regional level, this allows the defining of places of "passing through '' which gain population from other local government districts but lose population through migration within their own district. The connection between migration and regional structure is manifested in the fact that flows both between and within local government districts mainly involve the more urbanised population centres and areas with: high levels of unemployment.

    The Old Ammassuo Landfill (Espoo, Finland) covers an area of 52 hectares and contains about 10 million tonnes of waste that was landfilled between 1987 and 2007. The majority of this waste was mixed, of which about 57% originated from households. This paper aims at describing the management...... of the Old Ammassuo Landfill throughout its operational lifetime (1987-2007), and at developing an environmental evaluation based on life-cycle assessment (LCA) using the EASEWASTE-model. The assessment criteria evaluate specific categories of impact, including standard impact categories, toxicity......) and ecotoxicity in water chronic (ETwc). The largest impact potential was found for SGR and amounted to 57.6 person equivalent (PE) per tonne of landfilled waste. However, the SGR impact may not be viewed as a significant issue in Finland as the drinking water is mostly supplied from surface water bodies. Overall...

    The gray wolf ( Canis lupus) is a source of concern and a cause of damage to people's livelihoods. In Finland, as in most countries, actual damages are compensated according to the real lost value. However, often, the suffered damages are larger than what is compensated, and worries and fears are not accounted for at all. The purpose of our transdisciplinary action research is to contribute to the process of modifying the scientific, administrative, and everyday habits of mind in order to meet the practical prerequisites of living with the wolf. In 2014, we planned and participated in a process designed to update Finland's wolf population management plan. During our study, we applied e-deliberation, conducted a national wolf survey, and organized solution-oriented workshops in wolf territory areas around Finland. By applying abductive reasoning, we illustrate the basic features of an economic scheme that would help finance and coordinate practical modifications to the ecological, economic, and institutional circumstances and settings in wolf territory areas. The potential economic instrument is based on payments for improved ecostructures. In our paper, we describe the organization, functioning, and financing of this instrument in detail.

  11. Palaeoenvironment and shoreline displacement on Suursaari Island, the Gulf of Finland

    2000-01-01

    Full Text Available The island of Suursaari in the middle of the Gulf of Finland is exceptionally high (175 m a.s.l.. Sediment profiles from one mire and three lakes were investigated using diatom and pollen analysis, radiocarbon dating and levelling of the elevations of ancient shorelines. The pollen stratigraphy of the Lounatkorkiasuo Mire sediment suggests a sedimentary record dating from the late Allerød.The development of late-glacial vegetation went through the same phases as in southern Finland, however these are probably somewhat earlier on the island of Suursaari. There are differences in the Holocene vegetation history of the higher and lower areas of the island. Lake Ruokalahenjärvi was isolated around 10 000 BP during the initial phase of the Yoldia Sea and the diatom assemblage indicates that at that time brackish-water flow had not penetrated into the Gulfof Finland. Diatoms from the isolation sediments of Lake Liivalahenjärvi and Lake Veteljärvi indicate a freshwater environment for the Yoldia Sea final phase at 9500–9600 BP. Levelling of coastal formations on Suursaari Island reveals that the Late Weichselian and early Holocene ancient shorelines are 5–15 m higher than expected from the isobase data for similar land uplift areas on the mainland.The anomalous shoreline levels on Suursaari Island may be explained byirregular land uplift. By the time of the Litorina Sea differences in shoreline altitudes had disappeared.

    In the management of waste by the Industrial Power Company Ltd. (TVO) preparations are being made for the final disposal of unprocessed spent fuel into the Finnish bedrock. The site selection program will advance in three phases. The final disposal site must be made at the latest by the end of the year 2000, in accordance with a decision laid down by the Finnish Government. In the first phase, 1983-85, the main object is to find homogeneous stable bedrock blocks surrounded by fracture zones located at a safe distance from the planned disposal area. The work usually starts with a regional structural analysis of mosaics of Landsat-1 winter and summer imagery. Next an assortment of different maps, which cover the whole country, is used. Technical methods for geological and hydrogeological site investigations are being developed during the very first phase of the studies, and a borehole 1000 meters deep will be made in southwestern Finland. Studies for the final disposal of spent fuel or high-level reprocessing waste have been made since 1974 in Finland. General suitability studies of the bedrock have been going on since 1977. The present results indicate that suitable investigation areas for the final disposal of highly active waste can be found in Finland

    The area to the W-SW of the Lut Block in Iran has experienced numerous historical and recent destructive earthquakes. We examined a number of faults in this area that have high potential for generating destructive earthquakes. In this study a number of faults are introduced and named for the first time. These new faults are Takdar, Dehno, Suru, Hojat Abad, North Faryab, North Kahnoj, Heydarabad, Khatun Abad and South Faryab. For a group of previously known faults, their mechanism and geological offsets are investigated for the first time. This group of faults include East Nayband, West Nayband, Sardueiyeh, Dalfard, Khordum, South Jabal-e-Barez, and North Jabal-e-Barez. The N-S fault systems of Sabzevaran, Gowk, and Nayband induce slip on the E-W, NE-SW and NW-SE fault systems. The faulting patterns appear to preserve different stages of fault development. We investigated the distribution of active faults and the role that they play in accommodating tectonic strain in the SW-Lut. In the study area, the fault systems with en-echelon arrangement create structures such as restraining and releasing stepover, fault bend and pullapart basin. The main mechanism for fault growth in the region seems to be 'segment linkage of preexisting weaknesses' and also for a limited area through 'process zone'. Estimations are made for the likely magnitudes of separate or combined failure of the fault segments. Such magnitudes are used in hazard analysis of the region.

    Results from a survey of environmental gamma radiation levels in Finland after the Chernobyl accident 1986 were presented. The measurements were made by means of sensitive Geiger-counters and a gamma-spectrometer placed in cars. The results presented the level of external radiation caused by the cesium fallout on the first of October 1986. In the center of Southern Finland there are wide areas with exposure levels exceeding 0.04 μSv h -1 , areas exceeding 0.2 μSv h -1 being very rare. The surface area weighted mean dose rate for the 461 municipalities in Finland was 0.037 $mu$Sv h -1 (range 0-0.23 μSv h -1 ). The corresponding estimated surface activity of 137 Cs was 10.7 kBq m -2 . The population weighted mean dose rate was 0.051 μSv h -1 . Results from measurements at eight dose rate monitoring stations were presented as daily dose rate recordings in 1985-1986, the rate of decrease of the excess dose rate demonstrating quite large variations in the period from May to August. This indicated that the composition of the short-lived nuclides in the fallout varied from place to place. The influence of the meteorological conditions were reported with precipitation data from six days after the accident. There was a clear correlation between the results from precipitation and radiation measurements in different parts of Finland

  16. Adapting Bioretention Construction Details to Local Practices in Finland

    Directory of Open Access Journals (Sweden)

    Outi Tahvonen

    2018-01-01

    Full Text Available Bioretention is a method of storm water management that includes several processes following the natural hydrological cycle. Bioretention, or variations of it, include rain gardens and bioswales, infiltrates, filtrates, evapotranspirates, and help to store and manage storm water run-off. A bioretention cell retains water, removes pollutants, and provides water elements for urban green areas. Although bioretention is a promising method for multifunctional storm water management, its construction details should not be copied from other climatic areas. A direct application may dismiss local conditions, materials, and construction practices. This study aimed to adapt construction details for bioretention to Finnish local practices and conditions and to formulate bioretention constructions that balance water, soil, and vegetation. First, construction details were reviewed, then local adaptations were applied, and finally, the application and two variations of growing media in two construction depths were tested in a test field in Southern Finland. Sandy growing media allowed the efficient retention of water during the first year, but failed to provide vital growth. The use of topsoil and compost in the growing media improved growth, but held high electrical conductivity after infiltration. All the experimental cells in the test field showed activity during the melting periods, both during winter and spring. If bioretention plays a multifunctional role in urban design and engineered ecology, the design parameters should not only focus on storm water quantity, but also on quality management and vegetation growth.

    Full Text Available Most of the world has learned to ”see to Finland” over the last decade, beacuse of its reputation as a leading nation in educational achievement, as well as its many creative and diligent approaches in technology. Since 1990 Finnish researchers in media, technology and education have met annually to discuss research matters and further advances in the area. For the conference of 2016, held 13-15th April in Hämeenlinna, Finland, we were asked to have the best papers published in Seminar.net. After a rigourous review process we will print six papers, four in this issue and two in the next.Antti Syvänen, Jaana-Piia Mäkiniemi, Sannu Syrjä, Kirsi Heikkilä-Tammi and Jarmo Viteli, all of the University of Tampere, present the paper “When does the educational use of ICT become a source of technostress for Finnish teachers?» This interesting paper is based on the analysis of questionnaires filled in by 2741 Finnish teachers. It provides significant insight into what causes teachers to experience stress and alienation when using information and communication technologies (ICT in their classrooms.Tuulikki Keskitalo and Heli Ruokamo of Lapland University present a paper dealing with “Students’ Expectations and Experiences of Meaningful Simulation-Based Medical Education».

    The xenoliths of peridotites representing the subcontinental lithospheric mantle (SCLM) beneath SW Poland and adjacent parts of Germany occur in the Cenozoic alkaline volcanic rocks. Our study is based on detailed characterization of xenoliths occurring in 7 locations (Steinberg in Upper Lusatia, Księginki, Pilchowice, Krzeniów, Wilcza Góra, Winna Góra and Lutynia in Lower Silesia). One of the two major lithologies occurring in the xenoliths, which we call the "B" lithology, comprises peridotites (typically harzburgites) with olivine containing from 90.5 to 84.0 mole % of forsterite. The harzburgites contain no clinopyroxene or are poor in that mineral (eg. in Krzeniów the group "B" harzburgites contain pfu in ortho-, and pfu in clinopyroxene). The exception are xenoliths from Księginki, which contain pyroxenes characterised by negative correlation between mg# and Al. The REE patterns of both ortho- and clinopyroxene in the group "B" peridotites suggest equilibration with silicate melt. The rocks of "B" lithology were formed due to alkaline silicate melt percolation in the depleted peridotitic protolith. The basaltic melts formed at high pressure are usually undersaturated in both ortho- and clinopyroxene at lower pressures (Kelemen et al. 1992). Because of cooling and dissolution of ortho- and clinopyroxene the melts change their composition and become saturated in one or both of those phases. Experimental results (e.g. Tursack & Liang 2012 and references therein) show that the same refers to alkaline basaltic silicate melts and that its reactive percolation in the peridotitic host leads to decrease of Mg/(Mg+Fe) ratios of olivine and pyroxenes. Thus, the variation of relative volumes of olivine and orthopyroxene as well as the decrease of mg# of rock-forming silicates is well explained by reactive melt percolation in the peridotitic protolith consisting of high mg# olivine and pyroxenes (in the area studied by us that protolith was characterised by olivine

  20. Possibilities and future of wind power production in Finland

    1997-01-01

    The article was prepared for two presentations for Finnish MPs late autumn 1996 in connection of the handling of new energy taxation in Finland. The governmental proposal was going to favour the use of coal and unfavour the use of renewable energy sources. The total amount of installed wind power in Finland (7 MW) was compared to some other European countries. Anyhow it is well known that the wind potential in Finland due to its long coast line, large archipelago and great number of arctic mountains, all with very good wind climate, offers a great opportunity for effective exploitation of wind energy. The price of wind energy in Finland is 30 p/kWh (about 0,05 ECU) and it is estimated that with bigger power plan units it could be 20 p/kWh. Different ways to support wind energy production was presented with examples from Germany, Denmark and Sweden. (orig.) (8 refs.)

    Full Text Available Of the 30,000 children adopted yearly all over the world, about 200-300 come to Finland. A former adoption donor country, Finland started receiving international adoptees in the 1970s. Nowadays, there are about 3,000 internationally adopted persons in Finland. This paper focuses on the views and experiences of young Finnish international adoptees, who were interviewed during summer and autumn 2005. Altogether three group interviews and six individual interviews were carried out. The main aim was to study cultural identity and experiences of difference. The primary objective of this study is to give a voice to young international adoptees in Finland and present results as examples of how the dominant population adapts to difference.

    Nature tourism has been a growing business sector in the Barents area during the recent decades. With the purpose to develop nature tourism in a sustainable way, a cooperation project ABCGheritage - Arctic Biological, Cultural and Geological Heritage has been carried out. Project has received partial funding from the EU Kolarctic ENPI program. In the geoheritage part of the project the main activities were aimed to develop pro-environmental ways of geotourism in the area. The three main participants in the geoheritage part of the project are the Geological Survey of Finland, Northern Finland Office, the Geological Institute of the Kola Science Centre of the Russian Academy of Sciences and Bioforsk Soil and Environment from northeastern Norway. The duration of the project is 2012-2014 and most of the work has already been completed even if most of the results are not published yet. Totally ten different tasks have been implemented in the geological part of the project. The largest task has been the preparation of a geological outdoor map and guide book of the Khibiny Tundra locating in the central part of the Kola Peninsula. In Finland already 11 such maps have been published, and the experiences gained during their production have been used in this project, too. Geological heritage trails to the Khibiny Tundra have also been created and they will be drawn on the map. The second concrete result is the Barents Tour for Geotourist -guide, which will be published as a guide book, web pages and an exhibition. The route comprises ca 35 best geological demonstration sites along the circle route from northern Finland to northeastern Norway, from there to Kola Peninsula and then back to Finland. Information of the route will be available for all interested travelers. In addition to the geological outdoor map of the Khibiny Tundra and "Barents Tour for Geotourists"-guide, the primary outputs of the project are the geological nature trails on the field, geological

    The rising demand for natural gas in Finland which already uses more gas than any other Nordic country is noted. The natural gas market which is based on sales to large industries and for heating is compared to the market in Denmark which is geared to small private heating customers. Imports of Norwegian gas allowing increased sales for power generation in Finland, and the influence of the impending Finnish application for membership of the EC on the gas market are considered.

    Heating entrepreneurs produce heat locally and sell heat to the end user at an agreed price. Heat is usually produced by burning wood chips from the companys own forests or from the surrounding forests. There were more than 500 heating plants run by heating entrepreneurs in Finland in the beginning of 2012. Some thirty of them were situated in the area of Uusimaa in southern Finland. It seems that heating entrepreneurship is steadily gaining ground, since the amount of heating plants has increased annually by around twenty. TTS-Tyoetehoseura (Work Efficiency Institute) started the nationwide research and development of heating entrepreneurship in 1993. At that time there were only three heating companies in Finland. The first started to operate in Uusimaa during 1994-1998. Among the first heating plants to be built in 1998 were Perttula Vocational School (KEUDA) with 500 kiloWatts capacity in Nurmijaervi, Ohkola school with 200 kiloWatts capacity in Maentsaelae and the Vaestankvarn schoolfarm with 700 kiloWatts capacity in Inkoo, of which we will give more info about in this bulletin.

    The European Union (EU) enlargement of 2004 brings both opportunities and challenges for public health. It is believed that further integration will bring direct health benefits, mainly through improved socioeconomic conditions, but there are also risks associated with the EU expansion, in particular cross-border health risks, such as the impact of the internal EU market policy of free movement and migration on communicable disease patterns. Against this background, this article examines communicable disease policy development in Finland, Norway and Sweden in response to changing European political frontiers, in particular the EU accession of the Baltic States. The emphasis is on HIV/AIDS and tuberculosis. The study is based on a qualitative and quantitative approach, using two complementary methods: documentary analysis and stakeholder analysis. The article identifies a distinct pattern in communicable disease policy development between 1990 and 2005. The turn of the new millennium saw a sharp increase in national attention and the priority assigned to communicable diseases in Finland, Norway and Sweden. The article argues that this development is likely to be related to the rising national, regional and European awareness of the public health challenges associated with communicable diseases in today's borderless Europe. It also shows that the Baltic health situation is a particular concern for Finland. Although there is increasing national and regional activity within the communicable disease area, there is a need for a more effective European approach to tackle the future communicable disease challenges that may follow in an increasingly interdependent and integrated Europe.

    We studied whether incidence of all cancer sites combined was associated with the radiation exposure due to fallout from the Chernobyl accident in Finland. An emphasis was on the first decade after the accident to assess the suggested "promotion effect". The segment of Finnish population with a stable residence in the first post-Chernobyl year (2 million people) was studied. The analyses were based on a 250m × 250m grid squares covering all of Finland and all cancer cases except cancers of the breast, prostate and lung. Cancer incidence in four exposure areas (based on first-year dose due to external exposure Chernobyl accident (1981-1985) and after it (1988-2007) taking into account cancer incidence trends for a longer period prior to the accident (since 1966). There were no systematic differences in the cancer incidence in relation to radiation exposure in any calendar period, or any subgroup by sex or age at accident. The current large and comprehensive cohort analysis of the relatively low levels of the Chernobyl fallout in Finland did not observe a cancer promotion effect. Copyright © 2013 Elsevier Ltd.

    The Finnish Forest Research Institute inquired of the local forest management associations for their opinions about fuelwood consumption in their area. A further purpose was to establish a register of local fuelwood dealers. According to the inquiry the consumption of fuelwood has increased during the last five years and the increase will continue during the next three years. Although in some areas demand of fuelwood is greater than its supply, principally the fuelwood supply is sufficient. In Finland there seems to be 500 - 550 fuelwood dealers with sales over 50 m 3 /a. Half of them acquired the sold fuelwood from their own farm. (3 refs.)

    By following changes in 137 Cs concentration, during a time period, in water and fish it is possible to estimate the halving-times of the nuclides. Examples are given of estimations of halving-times for 137 Cs in water and fish in individual lakes, some larger surface water areas and in areas with the highest rainfall in Finland. Transfer coefficients from water to fish are given as a function of time in some lakes. Transfer coefficients from precipitation to fish have been calculated on an annual basis in the case of some species of fish. (AB)

    2002-01-01

    This Forestry Bulletin presents a review of the market situation for firewood processing devices in Finland during March 2002. The review is based on a questionnaire sent to device manufacturers. The firewood processing devices have traditionally been divided into three groups according to their functions: cross-cutting devices, splitting devices and cross-cutting and splitting devices. With a cross-cutting device the tree can be cross-cut only. Because it is easily possible to build the splitting function into a cross-cutting device, merely manufacturing a cross-cutting devices is rare. In all the splitting machines on the market, the splitting is carried out on a horizontally operated hydraulic cylinder pushing against a splitting blade. The types of cross-cutting blade mostly used in cross-cutting and splitting devices are circular i.e. circular saw blade, and chain saw. These devices are called firewood sawing machines. In firewood chopping machines that have a chopping blade, the wood is cross-cut using a spiral or guillotine blade. The splitting is done by a wedge blade or an axe blade. The firewood chopping machines can cross-cut and split stems up to a maximum of 20-22 cm in diameter. Circular blade firewood machines use either a cone screw or hydraulic cylinder and counter blade for splitting. They can handle wood of 20-30 cm thick in diameter. Machines using a chain saw can process stems of a maximum 30-45 cm thick in diameter. All firewood machines that work with a chain saw use a hydraulic cylinder and counter blade for splitting. According to the questionnaire responses, there were 14 (12 Finnish, one Norwegian and one Italian) manufacturers of firewood processing devices in the market. There were over 80 device models. There were only three cross-cutting devices, thirty splitting devices and forty cross-cutting splitting devices. The price range of the devices was 500-66,000 euros (including 22% VAT).

    The nuclear power generation fits perfectly with the long duration load profile of the Finnish power system. The good performance of the Finnish nuclear power has yielded benefits also to the consumers through its contribution to decreasing the electricity price. Furthermore, the introduction of nuclear power has resulted in a clear drop in carbon dioxide emissions from electricity generation in the shift of 1970's and 1980's. In the year 2001 the four Finnish nuclear power units at Loviisa and Olkiluoto generated 22.8 TWh electricity, equivalent to 28 per cent of the total consumption. Loviisa power station has a net output capacity of 2 x 488 MW, and Olkiluoto 2 x 840 MW. The capacity factors of the four nuclear units have been above 90 per cent, which are among the highest in the world. The energy-intensive process industries in particular have strong belief in nuclear power. In November 2000, Teollisuuden Voima company (TVO) submitted to the Finnish Government an application for decision in principle concerning the construction of a new nuclear power plant unit. The arguments were among other things to guarantee for the Finnish industry the availability of cheap electric energy and to meet the future growth of electricity consumption in Finland. The carbon-free nuclear power also represents the most efficient means to meet the Greenhouse Gas abatement quota of Finland. Simultaneously, the energy policy of the Government includes intensive R and D and investment support for the renewable energy sources and energy conservation, and the objective is also to replace coal with natural gas as much as reasonably possible. The fifth nuclear unit would be located in one of the existing Finnish nuclear sites, i.e. Olkiluoto or Loviisa. The size of the new nuclear unit would be in the range of 1000 to 1600 MW electric. The ready infrastructure of the existing site could be utilised resulting in lower investment cost for the new unit. The Finnish Government accepted the

    Finland is an industrialized country with extensive forest lands. Because of the structure of industry and the country`s geophysical conditions, large amounts of energy are consumed. In 1995, CO{sub 2} emissions from fossil fuels and peat and from industry totalled 56 Tg, as compared to 54 Tg in 1990. Wood burning released another 21 Tg of CO{sub 2} in 1995, but this is not counted in total emissions because even more carbon was bound up in the growing stock in the forests. Methane (CH{sub 4}) emissions totalled 241 Gg in 1995, nitrous oxide (N{sub 2}O) 18 Gg, nitrogen oxides 259 Gg, carbon monoxide (CO) 434 Gg and volatile organic compounds from human activities (NMVOC) 182 Gg. Emissions other than carbon dioxide were jointly equivalent to some 25 Tg of CO{sub 2} in terms of their direct or indirect greenhouse effect. These estimates are consistent wish the Intergovernmental Panel on Climate Change (IPCC) guidelines for estimating national greenhouse gas emissions and sinks. The minor deviations from the guidelines have been presented in this report. Trends in national greenhouse gas emissions and sinks to 2000 and beyond have been estimated in consultation with appropriate government departments, industry sectors, research institutions and other bodies. Wherever possible, these projections take into account the effect of current and planned policies and measures aimed at reducing emissions and enhancing sinks. The main focus in Finland`s climate strategy is to intensify those programmes for reducing greenhouse gas emissions that are already under way, such as efficiency improvements in the energy production and utilization system, and use of energy and carbon taxes. As well as limiting emissions of CO{sub 2} and other greenhouse gases, the Finnish action programme also includes measures to enhance carbon reservoirs and sinks. In its energy report to Parliament in autumn 1993, the Government adopted the goals of stopping increases in CO{sub 2} emissions from

    The Forest Energy Project of Central Finland (1994 - 1996) was one of the leading regional demonstration projects in Finland for testing and studying of the complete energy wood delivery chains and energy wood utilisation. The target of this provincial project was to collect and demonstrate the most promising energy wood procurement technologies and methods for utilisation of energy producers, forest industry and small and medium sized industries co- operating with forest owners, contractors and forest organisations. The project was a large development and technology transfer venture concentrated primarily on practical needs. Total delivery chains were formed of the best machine and method alternatives, and they were also demonstrated. The project offered hence a wide test field for regional and national techno / economical wood fuel development. The Forest Energy Project of Central Finland was a demonstration project supervised by the Regional Council of Central Finland. The project was a part of the national Bioenergy Research Programme. VTT Energy and the Forestry Board of Central Finland were responsible for the practical development work. A large number of provincial partners interested in wood fuels took part in the project. The project were carried out during the years 1994 - 1996. The total costs were 4.4 million FIM. The aim is to create a practical model for the entire system, by which enables the economically profitable increment of the utilisation of chip fuels in Central Finland by 100 GWh/1996 and 500 GWh/a (about 250 000 m{sup 3}) to the end of the decade.

  19. Distributed power-law seismicity changes and crustal deformation in the SW Hellenic ARC

    Full Text Available A region of definite accelerating seismic release rates has been identified at the SW Hellenic Arc and Trench system, of Peloponnesus, and to the south-west of the island of Kythera (Greece. The identification was made after detailed, parametric time-to-failure modelling on a 0.1° square grid over the area 20° E – 27° E and 34° N–38° N. The observations are strongly suggestive of terminal-stage critical point behaviour (critical exponent of the order of 0.25, leading to a large earthquake with magnitude 7.1 ± 0.4, to occur at time 2003.6 ± 0.6. In addition to the region of accelerating seismic release rates, an adjacent region of decelerating seismicity was also observed. The acceleration/deceleration pattern appears in such a well structured and organised manner, which is strongly suggestive of a causal relationship. An explanation may be that the observed characteristics of distributed power-law seismicity changes may be produced by stress transfer from a fault, to a region already subjected to stress inhomogeneities, i.e. a region defined by the stress field required to rupture a fault with a specified size, orientation and rake. Around a fault that is going to rupture, there are bright spots (regions of increasing stress and stress shadows (regions relaxing stress; whereas acceleration may be observed in bright spots, deceleration may be expected in the shadows. We concluded that the observed seismic release patterns can possibly be explained with a family of NE-SW oriented, left-lateral, strike-slip to oblique-slip faults, located to the SW of Kythera and Antikythera and capable of producing earthquakes with magnitudes MS ~ 7. Time-to-failure modelling and empirical analysis of earthquakes in the stress bright spots yield a critical exponent of the order 0.25 as expected from theory, and a predicted magnitude and critical time perfectly consistent with the figures given above.

    In the autumn of 1710 Helsinki was struck by the so-called oriental plague during four months. The infection was transferred by black rats which harboured fleas. The flea-bites caused boils. It was believed that the plague was air-borne, and the air was very humid that autumn. Big fires were lit in order to reduce the humidity, the purpose being to make it easier for the infected to breathe. Attempts were also made to dissect the boils. The carriers of the contamination came as refugees from Estland over the Gulf of Finland. The infection had spread from Turkey to Poland and Balticum after the defeat of the Finnish-Swedish army in the summer of 1709 at Poltava in Ucraine. Helsingfors (Helsinki) was struck extremely hard. About two-thirds of the inhabitants died of the pestilence. Some escaped by fleeing to the countryside. The plague spread through the country as far north as to Uleåborg (Oulu) and Cajana (Kajaani). Marketplaces became important centres of infection. With the advent of the frost in December the plague dwindled. At that time Helsinki was practically a dead town.

  1. The use of forest chips in Finland

    2001-01-01

    International commitments require the industrial world to restrict their greenhouse gas emissions. In Finland, where the annual timber cut per capita is more than ten times the average cut in the other EU countries, the primary means to reduce CO 2 emissions is to replace fossil fuels with forest biomass. The annual consumption of wood-based energy corresponds to 6 million tonnes of oil equivalent (toe) or almost 20% of the total primary energy consumption. The goal is to rise the annual production of wood-based energy to 7.8 million toe by 2010. Substantial part of the targeted increase could be obtained by forest chips produced of unmerchantable small-diameter trees and logging residues. The goal for 2010 is to use 5 million solid m 3 of forest chips, which equals to 0.9 million toe. The use of forest chips is increasing. About 474 000 solid m 3 of forest chips were used as fuel in 1999. At the moment, the growth is rapid especially in cogeneration plants producing both heat and electricity. The growth is based primarily on chips obtained from logging residues. The price of forest chips decreased considerably during the 1990s but the price range remained wide. Chips made of logging residues are cheaper than those made of small trees. The average price of forest chips at the plant, VAT excluded, is about 53 FIM per MWh. In Sweden, the average price is more than 40% higher

    Exceptionally low total ozone, up to 40 % below the normal level, was measured over Northern Europe during winter and spring in 1992 and 1993. In 1993 the depletion persisted up to the end of May, resulting in a significant increase in biologically effective ultraviolet (UV) radiation. The increases were significantly smaller in 1992 and 1994 than in 1993. A special interest in Northern Europe is the effect of high reflection of UV from the snow. The period from the mid March to the mid May is critical in Northern Finland, because in that time the UV radiation is intense enough to cause significant biological effects, and the UV enhancing snow still covers the ground. Moreover, there is some evidence of increasing springtime depletions of ozone over Arctic regions. In this study the increase of UV exposure associated with the ozone depletions was examined with measurements and theoretical calculations. The measurements were carried out with spectroradiometrically calibrated Solar Light Model 500 and 501 UV radiometers which measure the erythemally effective UV doses and dose rates. The theoretical UV doses and dose rates were computed with the clear sky model of Green

    The atmospheric nuclear bomb tests in the 1950s, '60s and '70s caused global radioactive fallout. After the reactor accident at Chernobyl on April 26, 1986, radioactive fallout was carried by by air streams to most parts of Europe. In 1987 radionuclides causing internal contamination were transported to man only via different foodchains and no longer via inhalation, as had happened immediately after the Chernobyl accident. To determine the level of radionuclides in the body and to estimate the internal radiation doses caused by the Chernobyl accident, whole-body counting measurements were performed. Ten different groups of people were measured during 1987. Three were local reference groups, two groups of radiation workers, one a population group representing the whole country and four groups representing those with special dietary habits. The weighted mean 137 Cs body burden in the population group was 2000 Bq at the end of 1987, the minimum body burden being 200 Bq and the maximum 10000 Bq. The measurement results showed that the maximum body burdens were reached in the summer 1987. The groups with special diets did not necessarily follow this pattern. The mean effective dose equivalents delivered in 1987 to people in Finland, estimated by using the measurement results of the population group, was 0.08 mSv, the corresponding dose equivalent in 1986 bein 0.06 mSv

    After the reactor accident at Chernobyl radioactive fallout was carried by air streams to most parts of Europe. In 1988 radionuclides causing internal contamination were transported to man only via foodchains and no longer via inhalation, as had happened immediately after the Chernobyl accident. To determine the level of radionuclides in the body and to estimate the internal radiation doses caused by the Chemobyl accident, whole-body counting measurements were performed. Nine different groups of people were measured during 1988. Three were local reference groups, two groups of radiation workers, one a population group representing the whole country and three groups representing those with special dietary habits. The weighted mean 137 Cs body burden in the population group was 1300 Bq at the end of 1988, the minimum body burden being 50 Bq and the maximum 7700 Bq. The measurement data showed that the maximum body burdens were reached in summer 1987. The group with special diets did not necessarily follow this pattern. The mean effective dose equivalents delivered to people in Finland in 1988, estimated by using the measurement data on the population goup, was 0.05 mSv the corresponding dose equivalent in 1987 being 0.08 mSv

    The deregulation of the electricity market may cause an increased pressure to reduce the costs of electricity generation. This makes a new challenge to the regulatory body to assess the impact of these changes on the safety of nuclear power plants. Accordingly, it is important to identify the risks to the nuclear power industry resulting from the economic deregulation. This paper is to discuss the current situation in Finland with regard to the economic deregulation of the electricity market and the experiences so far. A common view today is that the number of electricity generating power companies will be reduced in Europe because of tough competition in the electricity market. It is expected that only the biggest companies can stand the consequences of tough competition in electricity prices and the consequential pressure to reduce costs. In order to review the impact of deregulation of the electricity market some relevant points have been discussed in this paper such as change of ownership of power companies due to the economic pressure, the need to cut costs of the companies by reducing the number of their activities and increasing the efficiency in the remaining activities and/or outsourcing of activities. The need to pursue reduction or delay of planned investments in safety upgrades are discussed as well. (author)

    The deregulation of the electricity market may cause an increased pressure to reduce the costs of electricity generation. This makes a new challenge to the regulatory body to assess the impact of these changes on the safety of nuclear power plants. Accordingly, it is important to identify the risks to the nuclear power industry resulting from the economic deregulation. This paper is to discuss the current situation in Finland with regard to the economic deregulation of the electricity market and the experiences so far. A common view today is that the number of electricity generating power companies will be reduced in Europe because of tough competition in the electricity market. It is expected that only the biggest companies can stand the consequences of tough competition in electricity prices and the consequential pressure to reduce costs. In order to review the impact of deregulation of the electricity market some relevant points have been discussed in this paper, such as change of ownership of power companies due to the economic pressure, the need to cut costs of the companies by reducing the number of their activities and increasing the efficiency in the remaining activities and/or outsourcing of activities. The need to pursue reduction or delay of planned investments in safety upgrades are discussed as well. (author)

    The political and economic upheavals which have taken place in Eastern Europe have had an impact on radiation and nuclear safety throughout Europe. Emergency preparedness systems for unexpected nuclear events have been developed further in all European countries, and prosperous western nations have invested in improving the safety of East European nuclear power plants. The economic crisis facing countries of the former Soviet Union has also promoted illicit trade in nuclear materials; this has made it necessary for various border guards and police authorities to intensify their collaboration and to tighten border controls. On 3-4 October 1995, Finnish Centre for Radiation and Nuclear Safety (STUK) arranged a seminar on nuclear threats and emergency preparedness in Finland. In addition to STUK experts, a wide range of rescue and civil defence authorities, environmental health specialists and other persons engaged in emergency preparedness attended the seminar. The publication contains a compilation of reports presented at the seminar. The reports cover a broad spectrum of nuclear threats analyzed at STUK, the impacts of radioactive fallout on human beings and on the environment, and preparedness systems by which the harmful effects of radiation or nuclear accidents can, if necessary, be minimized.

    Sewage sludge from municipal wastewater treatment plants was studied to determine its radionuclide concentrations. Measurements were made to find out whether any radionuclides from the nuclear power stations at Loviisa and Olkiluoto and from hospitals and medical laboratories could be detected in sludge additional to those originating from global and Chernobyl fallout. In the treatment process of water, aluminium sulphate sludge is developed at treatment plants using surface water. This kind of sludge was measured since it also concentrates radionuclides. Fallout nuclides from the Chernobyl nuclear power station after the accident predominated in all sewage sludge samples in Finland. In 1987 six different radionuclides originating from the Chernobyl fallout were detected in sewage sludge. In spring when the snow melted and large quantities of run off water flowed into the treatment plants, the activity concentrations clearly increased, but then started decreasing again. At the end of the year the highest measured 137 Cs activity concentrations were below 1000 Bq kg -1 dry weight. The highest activity concentration in sludge originated from iodine used fro medical purposes

    Exceptionally low total ozone, up to 40 % below the normal level, was measured over Northern Europe during winter and spring in 1992 and 1993. In 1993 the depletion persisted up to the end of May, resulting in a significant increase in biologically effective ultraviolet (UV) radiation. The increases were significantly smaller in 1992 and 1994 than in 1993. A special interest in Northern Europe is the effect of high reflection of UV from the snow. The period from the mid March to the mid May is critical in Northern Finland, because in that time the UV radiation is intense enough to cause significant biological effects, and the UV enhancing snow still covers the ground. Moreover, there is some evidence of increasing springtime depletions of ozone over Arctic regions. In this study the increase of UV exposure associated with the ozone depletions was examined with measurements and theoretical calculations. The measurements were carried out with spectroradiometrically calibrated Solar Light Model 500 and 501 UV radiometers which measure the erythemally effective UV doses and dose rates. The theoretical UV doses and dose rates were computed with the clear sky model of Green

    The objective of the study was to investigate the seafloor of shallow areas around Olkiluoto island, western Finland. The surveys were carried out by Alleco Ltd. Posiva will use the data for modeling purposes. The investigations included bathymetric surveys, sediment sampling and assessment of benthic macrophytes and macrozoobenthos in the underwater parts of six pre-defined survey transects extending from land to the sea. Sediment sampling and the assessment of benthic organisms were done by SCUBA diving. The study area showed a great variation in environmental conditions. Olkiluoto stands between almost open sea and extremely sheltered river mouth area of Lapinjoki. Two of the transects were more than 7 meters deep and included both hard and soft sand bottom. Whereas rest of the transects were shallow with mostly soft clay, mud and silt bottom. Altogether 27 species of algae including five species of stoneworts (Charophyta), one species of water moss (Bryophyta) and 16 species of vascular plants (Tracheophyta) were found. The most abundant group was vascular plants, between the other groups of macroalgae big differences in the abundance were not seen. Furthermore altogether 43 species of macrozoobenthos (Invertebrata) were found, of which six species were sessile bottom fauna (permanently attached fauna). The most abundant groups in the bottom samples were bivalves (Lamellibranchiata) (996 individuals per m 2 ), snails (Gastropoda) (739 individuals per m 2 ) and polychaetes (Polychaeta) (542 individuals per m 2 ). The total abundance of macrozoobenthos on all transects was 2 899 individuals per m 2 . The biggest groups by biomass were bivalves (fresh weight 87 054 mg per m 2 ) and polychaetes (fresh weight 12 983 mg per m 2 ). Transect 1 was the richest in number of species of the deep and exposed transects 1 and 2. The transect 5 had the highest diversity of all the shallow soft bottom transects 3, 4, 5 and 5a.

    This report presents the numerical results of air quality studies of the city of Espoo in southern Finland. This city is one of the four cities in the Helsinki metropolitan area, having a total population of 850 000. A thorough emission inventory was made of both mobile and stationary sources in the Helsinki metropolitan area. The atmospheric dispersion was evaluated using an urban dispersion modelling system, including a Gaussian multiple-source plume model and a meteorological pre-processing model. The hourly time series of CO, NO{sub 2} and SO{sub 2} concentrations were predicted, using the emissions and meteorological data for the year 1990. The predicted results show a clear decrease in the yearly mean concentrations from southeast to northwest. This is due in part to the denser traffic in the southern parts of Espoo, and in part to pollution from the neighbouring cities of Helsinki and Vantaa, located east of Espoo. The statistical concentration parameters found for Espoo were lower than the old national air quality guidelines (1984); however, some occurrences of above-threshold values were found for NO{sub 2} in terms of the new guidelines (1996). The contribution of traffic to the total concentrations varies spatially from 30 to 90 % for NO{sub 2} from 1 to 65 % for SO{sub 2} while for CO it is nearly 100 %. The concentrations database will be further utilised to analyse the influence of urban air pollution on the health of children attending selected day nurseries in Espoo. The results of this study can also be applied in traffic and city planning. In future work the results will also be compared with data from the urban measurement network of the Helsinki Metropolitan Area Council. (orig.) 19 refs.

    Full Text Available Ungulate–vehicle collisions are intensively studied in many countries. However, limited knowledge exists on how many animals struck actually die due to collisions and whether differences in traffic mortality occur between species living in the same area. In this study, we estimated a kill rate (the proportion of individuals killed/struck and, in relation to their winter population sizes, the collision and traffic mortality rates for four ungulate species (moose Alces alces, white-tailed deer Odocoileus virginianus, roe deer Capreolus capreolus, and fallow deer Dama dama. We used an unofficial collision register collected between 2001 and 2012 (a total of 12 years by voluntary hunters from the Hyvinkää Game Management Area (323 km2 located in southern Finland. The population estimates used were based on annual snow track censuses. A total of 497 ungulates were involved in collisions during the study period. Of these, 76% were killed directly or put down afterwards. Roe deer had the highest kill rate; 95% of struck individuals died. White-tailed deer had the highest collision and traffic mortality rates (8.0% and 6.5% of the winter population, respectively, followed by moose (6.5 % and 4.5%, roe deer (3.9% and 3.7%, and fallow deer (3.2% and 2.1%. As we found the collision and traffic mortality rates to be unequal between species, we recommend separately reporting all ungulate species when compiling collision statistics. We additionally suggest that local managers should be aware of ungulate collision and traffic mortality rates in their areas and should use this knowledge when planning annual harvest.

    This is the first report of ostreid herpesvirus 1 microvariant (OsHV-1 µVar) infecting natural oyster beds located in Huelva (SW Spain). The virus was detected in 3 oyster species present in the intertidal zone: Crassostrea gigas (Thunberg, 1793), C. angulata (Lamarck, 1819) and, for the first time, in Ostrea stentina Payraudeau, 1826. Oysters were identified by a specific polymerase chain reaction (PCR) and posterior restriction fragment length polymorphism (RFLP) analysis based on cytochrome oxidase I (COI) mitochondrial DNA. Results confirmed that C. angulata still remains the dominant oyster population in SW Spain despite the introduction of C. gigas for cultivation in the late 1970s, and its subsequent naturalization. C. angulata shows a higher haplotype diversity than C. gigas. OsHV-1 virus was detected by PCR with C2/C6 pair primers. Posterior RFLP analyses with the restriction enzyme MfeI were done in order to reveal the OsHV-1 µVar. Detections were confirmed by DNA sequencing, and infections were evidenced by in situ hybridization in C. gigas, C. angulata and O. stentina samples. The prevalence was similar among the 3 oyster species but varied between sampling locations, being higher in areas with greater harvesting activities. OsHV-1 µVar accounted for 93% of all OsHV-1 detected.

    The anthropogenic pollution along the coastline of the eastern Gulf of Finland was studied through a range of methods, including analyses of metal contamination in water, surface sediments, accumulated algal biomass and its correlation with resistant microbiota. According to concentrations, the main pollutants in water were copper and manganese. Influence of Nuclear Power Plant was remarkable in adjacent areas and was expressed in high concentrations of molybdenum, nickel, copper and other elements in the water. Relatively high concentrations of copper, lead and zinc were found in sediments. Microbial tolerance appeared to be correlated with the concentration of the metals in sediments. Higher tolerance levels were found in sediment samples from more polluted stations. Macroalgae, which were massively developed in the coastal zone, had shown high level of metal bioaccumulation. Analyses of carbon, nitrogen and phosphorus content of algal tissues allowed the estimation of additional nutrient loading from accumulated decaying algal biomass on the coastal zone of the eastern Gulf of Finland. Mass development of algae in coastal area may contribute to accumulation of organic matter and associated metals. In our study the highest metal concentrations in sediments were found at the sites with dense and continuous layer of fresh and decaying macroalgal biomass, accompanied by hypoxic conditions. Also our study has shown that accumulated biomass may be a significant source of nutrients in the coastal ecosystem. - Highlights: • We studied heavy metal pollution in the coastline of the eastern Gulf of Finland. • Sediments, water, mass macroalgae and microbiota were included into analyses. • Eutrophication and nutrient loading remain the main problem of the studied area. • Macroalgae contribute to accumulation of organic matter, nutrient, and heavy metal. • Pollution in the studied area is caused by a combination of different factors.

    Recent studies have shown a considerable increase in the abundance of rowan (Sorbus aucuparia) saplings in urban forests in Finland, yet the reasons for this increase are not well understood. Here we investigated whether canopy cover or tree species composition, i.e., the basal areas of different tree species in Norway spruce dominated urban forests, affects the abundances of rowan seedlings, saplings and trees. Altogether 24 urban forest patches were investigated. We sampled the number of rowan and other saplings, and calculated the basal areas of trees. We showed that rowan abundance was affected by tree species composition. The basal area of rowan trees (≥ 5 cm in diameter at breast height, dbh) decreased with increasing basal area of Norway spruce, while the cover of rowan seedlings increased with an increase in Norway spruce basal area. However, a decrease in the abundance of birch (Betula pendula) and an increase in the broad-leaved tree group (Acer platanoides, Alnus glutinosa, Alnus incana, Amelanchier spicata, Prunus padus, Quercus robur, Rhamnus frangula and Salix caprea) coincided with a decreasing number of rowans. Furthermore, rowan saplings were scarce in the vicinity of mature rowan trees. Although it seems that tree species composition has an effect on rowan, the relationship between rowan saplings and mature trees is complex, and therefore we conclude that regulating tree species composition is not an easy way to keep rowan thickets under control in urban forests in Finland.

    The paper describes the surveillance of radioactive substances in agricultural products in Finland after the end of April 1986. The main objective was to assess the dietary intake of fallout radionuclides via milk, meat, cereals and eggs in Finland during the period May-December 1986. In spring 1986 the sampling programmes were extended on the basis of the continuous surveys carried out earlier. The sampling of different types of produce covered a considerable part of the main production areas. The frequency of the sampling was greatly increased from that in previous years, specially in spring and summer, in order to follow the temporal variation in the contents of radionuclides in milk and meat. Gamma-emitting radionuclides, especially ''1''3''1I, ''1''3''4Cs and ''1''3''7Cs, were measured on all samples. ''8''9Sr and ''9''0Sr were determined on the milk and cereal samples used for nationwide assessments. The mean dietary intakes of radionuclides in May-December 1986, calculated from the average consumption of foodstuffs in Finland and the nationwide production-weighted mean mean contents of radionuclides. Contamination of agricultural products due to fallout radionuclides did not cause any restrictions for their use in Finland

    A national crowdsourcing-based tick collection campaign was organized in 2015 with the objective of producing novel data on tick distribution and tick-borne pathogens in Finland. Nearly 20 000 Ixodes ticks were collected. The collected material revealed the nationwide distribution of I. persulcatus for the first time and a shift northwards in the distribution of I. ricinus in Finland. A subset of 2038 tick samples containing both species was screened for Borrelia burgdorferi sensu lato (the prevalence was 14.2% for I. ricinus and 19.8% for I. persulcatus), B. miyamotoi (0.2% and 0.4%, respectively) and tick-borne encephalitis virus (TBEV; 0.2% and 3.0%, respectively). We also report new risk areas for TBEV in Finland and, for the first time, the presence of B. miyamotoi in ticks from mainland Finland. Most importantly, our study demonstrates the overwhelming power of citizen science in accomplishing a collection effort that would have been impossible with the scientific community alone.

    Heating entrepreneurs are farmers, who usually have a wood-lot of their own, or entrepreneurs, who have undertaken to look after the supply of fuel to real estates and their heating. The TTS- Institute conducted an analysis of the scope of heating enterpreneurship in connection with the project belonging to the national Bioenergy Research Programme. According to the responses obtained in a mail questionnaire study conducted in autumns 1996, and other data obtained on the subject, there were 36 active heating entrepreneur sites in Finland in December 1996. Heating enterpreneurship, usually involving the supply of chipped wood, has become more common during the past few years. In 1994, it was started at ten places, in 1995 at eight places, and in 1996 at twelve places. The majority, nearly three quarters, of the heating enterpreneurship sites at the end of 1996 were school buildings and one fifth were district heating plants. The solid fuel boiler capacity of all the plants in the study was 11.5 MW. The district heating plants were 0.3-2.5 MW in capacity, the school buildings were in the 60-500 kW range, old peoples'' homes had capacities of 300-370 kW. Except for one school building using sod peat as primary fuel, wood chips was the primary fuel used by institutional buildings. The enterprise form was that of an entrepreneur or a pool formed by entrepreneurs in the case of 27 entrepreneurs, a company in the case of 6, and a co-operative society in the case of three. There were 56 heating-enterpreneurship sites at the implementation or planning stage. Four fifths of them involved heat generation capacity of less than 500 kW and one fifth a capacity of 0.5-2.0 Mw Tyoetehoseuran Metsaetiedote. 13 refs., 3 figs

    Background Non‐married persons are known to have poor mental health compared with married persons. Health differences between marital status groups may largely arise from corresponding differences in interpersonal social bonds. However, official marital status mirrors the social reality of persons to a decreasing extent, and living arrangements may be a better measure of social bonds. Little is known about mental health in different living arrangement groups. This study aims to establish the extent and determinants of mental health differences by living arrangement in terms of psychological distress (GHQ) and DSM‐IV psychiatric disorders (CIDI). Methods Data were used from the nationally representative cross sectional health 2000 survey, conducted in 2000–1 in Finland. Altogether 4685 participants (80%) aged 30–64 years were included in these analyses; comprehensive information was available on measures of mental health and living arrangements. Living arrangements were measured as follows: married, cohabiting, living with other(s) than a partner, and living alone. Results Compared with the married, persons living alone and those living with other(s) than a partner were approximately twice as likely to have anxiety or depressive disorders. Cohabiters did not differ from the married. In men, psychological distress was similarly associated with living arrangements. Unemployment, lack of social support, and alcohol consumption attenuated the excess psychological distress and psychiatric morbidity of persons living alone and of those living with other(s) than a partner by about 10%–50% each. Conclusions Living arrangements are strongly associated with mental health, particularly among men. Information on living arrangements, social support, unemployment, and alcohol use may facilitate early stage recognition of poor mental health in primary health care. PMID:16698975

    Good-quality cardiopulmonary resuscitation (CPR) is highlighted in the International Resuscitation Guidelines, but clinically the quality of CPR is often poor. Education of CPR has a major role in the primary skills imparted to students. Different methods can be used to teach CPR quality. We evaluated the current status of their usage in Finland institutes teaching students of emergency medicine at different levels. The following institutes were included in an anonymous survey: medical schools (teaching future physicians), universities of applied sciences (paramedics), colleges (emergency medical technicians) and emergency services college (fire-fighters). Hours of teaching theory lessons of CPR and hours of small group training were evaluated. In particular, we focussed on the teaching methods for adequate chest compression rate and depth. Twenty-one of 30 institutes responded to the questionnaire. The median for hours of theory lessons of CPR was 8h (range: 2-28 h). The median for hours of small group training was 10 (range: 3-40 h). The methods of teaching adequate chest compression rate were instructors' visual estimation in 28.5% of the institutions, watch in 33.3%, metronome in 9.5% and manikins' graphic in 28.5% of institutions. The methods of teaching adequate chest compression depth were instructors' visual estimation in 33.3%, in manikins light indicators in 23.8% and manikins' graphics in 52.3% of institutions. The hours of theoretic lessons and small group training vary widely among different institutes. In one-third of institutions, the instructor's visual estimation was a sole method used to teach adequate chest compression rate and depth. Different technical methods were surprisingly seldom used.

  3. New NPP Construction Experience in Finland

    The paper discusses the experiences of the new nuclear power plant construction projects. The topics include the licensing and regulatory oversight process, completion of the design prior to construction, experience and know-how of the participating organisations, quality management in a nuclear construction project, safety culture aspects in a nuclear construction project, and the role and importance of regulator’s oversight. Finland has recent experience of new nuclear power plant construction, one plant unit being under construction close to commissioning phase and one plant unit in construction license phase. Each nation is solely responsible for the safety of its nuclear installations. Therefore, there are also national practices how nuclear power plants are licensed and how the safety and quality of these plants are verified during construction and operation. Differences in licensing, regulations and regulatory practices may have an impact on the design of the plant. There may be differences in how the detailed design has to be documented and how and when it needs to be submitted for approval to the regulator. To avoid surprises due to differences, it is beneficial for the owner and plant vendor to familiarize themselves early enough on the national practices and regulations to ensure that regulatory expectations and processes can be taken into account in the project implementation. In addition, the owner and the plant vendor have to understand what are the national safety goals and safety requirements that the plant has to fulfil, and what they mean to the detailed design of the plant. These have to be clarified and explicitly defined by the owner in terms of design criteria in the bidding documentation to avoid difficulties in the future steps of the project.

  4. Productivity of semi-domesticated reindeer in Finland

    Full Text Available In spite of a twofold increase in the density of reindeer in Finland from 1974 to 1987, meat production per reindeer increased during this period. This was possible due to calf harvesting and supplemental feeding. Results from multiple regression models indicated that calf harvesting influenced both per unit area and per capita production more than supplemental feeding. Correlation between meat production and animal density decreased with increased supplemental feeding. Traditionally, southern and central herds of reindeer fed mainly on arboreal lichens in late winter; however, due to large-scale logging, woodlands rich of arboreal lichens had been greatly reduced. Economic carrying capacity of the winter range apparently has been exceeded in the south; a heavy crash in the number of reindeer is likely if supplemental feeding ceases. In northern herds, intensive calf harvesting enabled satisfactory yield without supplemental feeding.

    Ageing of radioactive fallout also signifies that contributions of various foodstuffs to the human ingestion dose will change with time. The long-term contamination of forest vegetation has motivated studies on contribution of wild food to dietary radiocaesium and radiostrontium. Consumption rates of these foodstuffs have shown variation by geographical regions in Finland, the loss of radiocaesium during cooking of mushrooms has been found significant, and the approximation of the loss using survey data on the actual practices in households was also shown important for dietary assessment. Forest industry needs information for planning its own emergency response, particularly concerning production of acceptable timber after contamination of forests by radioactive fallout. In recent years experimental evidence has been obtained for the mitigating effect of forest management methods, namely soil preparation and fertilisation, on radioactive contamination of forest vegetation. Thereby realistic options for intervention have been suggested. Further testing will improve the information on effectiveness of different methods and duration of management influence in different types of forests. Results from systematic field experiments have also provided data and conceptual views for forest modelling, e.g. for RODOS, a European decision support system for off-site emergency preparedness. The future topics in terrestrial radioecology will altogether support production of safe foodstuffs and safe use of forests after contamination of rural areas. Evaluation of practicability of countermeasures will greatly benefit from measured radioecological parameters in the contaminated areas and from additional field tests. Natural radionuclides and their connection to both agricultural and semi-natural dose pathways ought to be studied. Radiation impact due to bioenergy production and use of ash is close to forest ecosystem studies. Returning of wood ash to forests will maintain and

    Airborne laser scanning (ALS) is a widely spread operational measurement tool for obtaining 3D coordinates of the ground surface. There is a need for calibrating the ALS system and a test field for ALS was established at the end of 2013. The test field is situated in the city of Lahti, about 100 km to the north of Helsinki. The size of the area is approximately 3.5 km × 3.2 km. Reference data was collected with a mobile laser scanning (MLS) system assembled on a car roof. Some streets were measured both ways and most of them in one driving direction only. The MLS system of the Finnish Geodetic Institute (FGI) consists of a navigation system (NovAtel SPAN GNSS-IMU) and a laser scanner (FARO Focus3D 120). In addition to the MLS measurements more than 800 reference points were measured using a Trimble R8 VRS-GNSS system. Reference points are along the streets, on parking lots, and white pedestrian crossing line corners which can be used as reference targets. The National Land Survey of Finland has already used this test field this spring for calibrating their Leica ALS-70 scanner. Especially it was easier to determine the encoder scale factor parameter using this test field. Accuracy analysis of the MLS points showed that the point height RMSE is 2.8 cm and standard deviation is 2.6 cm. Our purpose is to measure both more MLS data and more reference points in the test field area to get a better spatial coverage. Calibration flight heights are planned to be 1000 m and 2500 m above ground level. A cross pattern, southwest-northeast and northwest-southeast, will be flown both in opposite directions.

    Full Text Available Abstract Background Recent studies have revealed expansion by an array of Filarioid nematodes' into the northern boreal region of Finland. The vector-borne nematode, Setaria tundra, caused a serious disease outbreak in the Finnish reindeer population in 2003–05. The main aim of this study was to understand the outbreak dynamics and the rapid expansion of S. tundra in the sub arctic. We describe the vectors of S. tundra, and its development in vectors, for the first time. Finally we discuss the results in the context of the host-parasite ecology of S. tundra in Finland Results Development of S. tundra to the infective stage occurs in mosquitoes, (genera Aedes and Anopheles. We consider Aedes spp. the most important vectors. The prevalence of S. tundra naturally infected mosquitoes from Finland varied from 0.5 to 2.5%. The rate of development in mosquitoes was temperature-dependent. Infective larvae were present approximately 14 days after a blood meal in mosquitoes maintained at room temperature (mean 21 C, but did not develop in mosquitoes maintained outside for 22 days at a mean temperature of 14.1 C. The third-stage (infective larvae were elongated (mean length 1411 μm (SD 207, and width 28 μm (SD 2. The anterior end was blunt, and bore two liplike structures, the posterior end slight tapering with a prominent terminal papilla. Infective larvae were distributed anteriorly in the insect's body, the highest abundance being 70 larvae in one mosquito. A questionnaire survey revealed that the peak activity of Culicidae in the reindeer herding areas of Finland was from the middle of June to the end of July and that warm summer weather was associated with reindeer flocking behaviour on mosquito-rich wetlands. Conclusion In the present work, S. tundra vectors and larval development were identified and described for the first time. Aedes spp. mosquitoes likely serve as the most important and competent vectors for S. tundra in Finland. Warm summers

    Atmospheric mercury concentrations and mercury fluxes measured during the period 1995 to 1999 at the AMAP master station of Pallas, a remote station in Northern Finland, and at Roervik an EMEP station located on the west coast of Sweden are reported. The results are discussed and compared with atmospheric mercury data generated within the EU-project, Mercury over Europe (MOE). Total particulate mercury exhibit a strong south to north gradient with the highest concentrations in the south, near source areas in Central Europe. Mercury in precipitation also exhibits a south to north gradient.

  9. Patterns of Hits to the Nearshore from a Major Fairway in the Gulf of Finland

    The Baltic Sea hosts one of the heaviest ship traffic in the world. Although relatively small in size, still up to 15% of the world's cargo is transported along its numerous fairways. The largest threat to the environment is oil transportation that has increased more than by a factor of two in 2000-2008 and a 40% increase is expected by the year 2015. One of the major marine highways in the European waters enters the Baltic Sea through the Danish Straits, crosses the Baltic Proper and stretches through the Gulf of Finland to Saint Petersburg. An area that is highly vulnerable to ship pollution is the nearshore that usually has the largest ecological value. While the probability of coastal pollution for open ocean coasts can be reduced by shifting ship routes farther offshore, the problem for narrow bays, like the Gulf of Finland, is how to minimize the probability of hitting any of the coasts. To a certain extent, light can be shed to this problem by means of quantification of the offshore areas in terms of their ability to serve a danger to coastal environment if pollution would happen in these areas. A convenient way to address this problem is to use statistical analysis of a large number of Lagrangian trajectories of test particles representing the potential pollution and passively carried by surface currents. In this paper, we make and attempt to quantify the link between potential sources of pollution along an existing fairway and the sections of the coast reached by current-driven pollution. The problem is analysed by means of considering hits to the nearshore from a major fairway in the Gulf of Finland and by making sure whether certain parts of the coast are hit by pollution particles most frequently and whether or not these pollution particles stem from certain specific parts of the fairway. Trajectories are simulated in the Gulf of Finland by placing tracers among a line that follows one of the major fairways from the Baltic Proper to Saint Petersburg

    Anthropogenic impacts on the Earth`s atmosphere are expected to cause significant global climate changes during the next few decades. These changes will have many consequences both in nature and on human activities. In order to investigate the implications of such changes in Finland, a six-year multidisciplinary national research programme on climate and global change, the Finnish Research Programme on Climate Change (SILMU), was initiated in 1990. The key research areas were: (1) quantification of the greenhouse effect and the magnitude of anticipated climate changes, (2) assessment of the effects of changing climate on terrestrial and aquatic ecosystems, and (3) development of mitigation and adaptation strategies

    The selection of the most suitable software life cycle process is of paramount importance in any space SW project. Despite being the preferred choice, the waterfall model is often exposed to some criticism. As matter of fact, its main assumption of moving to a phase only when the preceding one is completed and perfected (and under the demanding SW schedule constraints) is not easily attainable. In this paper, a tailoring of the software waterfall model (named “Robust Software Feedback Model”) is presented. The proposed methodology sorts out these issues by combining a SW waterfall model with a SW prototyping approach. The former is aligned with the SW main production line and is based on the full ECSS-E-ST-40C life-cycle reviews, whereas the latter is carried out in advance versus the main SW streamline (so as to inject its lessons learnt into the main streamline) and is based on a lightweight approach.

  15. The 2005 energy year in Finland: Electricity consumption down

    Electricity consumption declined by 2.5% in 2005, largely as a result of a six-week labour dispute in the paper indusry and mild weather conditions, according to a report on energy industry develop rents in 2005 published by Finnish Energy Industries. Over the longer term, energy consumption is forecast to grow by close to 2% a year. Water levels in waterways and water systems across the Nordic countries returned to normal in 2005 after a long period of reduced resources, stabilising hydropower output generally Following high levels of electricity exports westwards in 2004, electricity imports from the West reached almost record levels in Finland in 2005. Together with imports from Russia, Finland imported more electricity last year than ever before - and a full fifth of Finland's energy needs were covered by net electricity imports in 2005. Two thirds of imports came from Russia, with imports reaching almost the maximum capacity of the countries' interconnectors

  16. Air Pollution Mortality in Denmark, Finland, and Sweden

    2009-01-01

    Full Text Available The adverse health consequences of air pollution are of concern currently and there is a fear that these consequences escalate along with economic growth. The effect of economic growth on air pollution deaths is analyzed in Denmark, Finland, and Sweden by applying the Environmental Kuznets Curve approach, according to which economic growth has competing effects on air pollution and related deaths. On the one hand, emissions tend to increase as the scale of economic activity increases, but on the other hand, consumers and firms in richer countries use cleaner goods and adopt cleaner technologies. In Denmark and Finland, the latter effects are stronger, while in Sweden the opposite is true. Therefore, air pollution deaths will decrease in Denmark and Finland but increase in Sweden. Since country's own emissions do not determine air pollution completely, the paper briefly analyzes emissions from the Baltic countries and Russia.

    The TTS Institute studied the operations of chopped firewood merchants and described the cost structure of commercial chopped firewood production. The research material was collected via postal questionnaire in 2002 after being sent to those firewood merchants assumed to be selling chopped firewood. Acceptable responses were received from 244 firewood merchants. In addition, ten firewood merchants were interviewed. In 2001, the firewood merchants sold an average of 151 m 3 of chopped firewood. Half of the firewood merchants sold less than 51 m 3 of chopped firewood. The main source of income for the majority of chopped firewood merchants was agriculture and forestry. If approximately 300,000 m 3 of chopped firewood is sold annually, according to the research there are about 2,000 chopped firewood merchants in Finland. However, only a very few entrepreneurs get their main income from the chopped firewood trade. The majority of raw material for chopped firewood came from the merchant's own forest. Birch was the most commonly used species. 54% of the chopped firewood was made from pulpwood, 19% from pole size trees and 18% from split firewood. The drying methods for chopped firewood were most often natural drying outside in covered stocks or cages, natural drying in stacks or natural drying of mechanically debarked or debarked timber in stacks. Less than a tenth of the merchants dried their chopped, firewood using artificial cold air-drying. The share of packaged chopped firewood was 14% i.e. approximately 42,000 m 3 . Chopped firewood was packed mostly into small packages (about 10 kg). The chopped firewood trade is a local business: the average transport distance from the merchant's store to the customer was 25 km. The chopped firewood merchants delivered 73% of lie chopped firewood themselves. An agricultural tractor and a trailer were the most common transport method. The most important customer group is detached houses. The average production costs amongst the

    Full Text Available Abstract Background The Finnish chiropractic profession is young and not fully accepted by Finnish healthcare authorities. The demographic profile and style of practice has not been described to date. However, as the profession seems to be under rapid development, it would be of interest to stakeholders, both chiropractic and political, to obtain a baseline description of this profession with a view to the development of future goals and strategies for the profession. The purpose of this study was to describe the chiropractic profession in Finland in relation to its demographic background, the demographics of their clinics, practice patterns, interactions with other health care practitioners and some of the professions' plans for the future. Methods A structured questionnaire survey was conducted in 2005, in which all 50 members of the Finnish Chiropractic Union were invited to participate. Results In all, 44 questionnaires were returned (response rate 88%. Eighty percent of the respondents were men, and 77% were aged 30 to 44 years old, most of whom graduated after 1990 with either a university-based bachelors' or masters' degree in chiropractic. Solo practice was their main practice pattern. The vast majority described their scope of practice to be based on a musculoskeletal approach, using the Diversified Technique, performing Soft Tissue Therapy and about two-thirds also used an Activator Instrument (mechanical adjusting instrument. The mean number of patient visits reported to have been seen weekly was 59 of which nine were new patients. Most practitioners found this number of patients satisfactory. At the initial consultation, 80% of respondents spent 30–45 minutes with their patients, 75% spent 20–30 minutes with "new old" patients and on subsequent visits 80% of respondents spent 15–30 minutes. Interactions with other health care professions were reasonably good and most of chiropractors intended to remain within the profession

    2012-04-01

    Full Text Available An impressive SGD in Kalogria Bay (SW Peloponnissos was surveyed for the first time in 2006, revealing the existence of 2 major and 2 minor point sources of freshwater (salinity ~l-2; the discharge was ~ 1000 m3 h−1. The major point source was located in a karstic cavity at 25 m depth. In July 2009, and for a period of one year, the site was monitored intensively. During summer, the underwater discharge was not very strong, the water was flowing from many dispersed points, and salinity range was 20–36. During autumn and winter, flow velocity increased considerably (> 1 m s−1, and the SGDs discharged water of low salinity (< 2. Gradually, the smaller SGDs ceased their operation, and the major SGD emanated brackish water during spring and summer, thus hampering the possibilities of freshwater exploitation, in a touristic area which suffers from great aridity and water demand is high during summer.

    2017-02-01

    The SW of Iberia is currently undergoing compression related to the convergence between Nubia and Iberia. Multiple compressive structures, and their related seismic activity, have been documented along the diffuse Nubia-Iberia plate boundary, including the Gorringe bank west of the Gulf of Cadiz, and the Betic-Rif orogen to the east. Despite seismic activity indicating a dominant compressive stress along the Algarve margin in the Gulf of Cadiz, the structures at the origin of this seismicity remain elusive. This paper documents the contractional structures that provide linkage across the Gulf of Cadiz and play a major role in defining the present-day seismicity and bathymetry of this area. The structures described in this paper caused the Neogene inversion of the Jurassic oblique passive margin that formed between the central Atlantic and the Ligurian Tethys. This example of a partially inverted margin provides insights into the factors that condition the inversion of passive margins.

    2009-01-01

    A previous study on seabed sediments of the Bay of Cadiz (SW of Spain) enabled us to identify several relations between sedimentological variables and activity concentrations of environmental radionuclides such as 137 Cs, 226 Ra, 232 Th and 40 K. In this paper the study has been extended to a large neighbouring inter-tidal area in order to establish if the above mentioned models can be generalized. As a result we have determined that the measured activity concentrations are closely to the values predicted by the theoretical models (correlation coefficient range = 0.85-0.93). Furthermore, the proposal model for granulometric facies as a function of activity concentrations of the abovementioned radionuclides provides for the sediments distribution a representation which agrees with the values of the tidal energy distribution obtained using numeric models calibrated with experimental data from current meters and water level recorders

  2. How do Locals in Finland Identify Resident Foreigners

    2008-01-01

    Full Text Available This study examines the identi? cation by Finns of foreign residents in Finland by analyzing data from a representative sample survey carried out in 2002. When people were asked to name a group of foreigners residing in Finland, the majority ?rst mentioned Somalis, despite the fact that only 4 percent of foreign residents are Somali and 6 percent of foreign-language speakers speak Somali. The general tendency when identifying resident foreigners is to refer primarily to ethnic or national groups; references to status (e.g. refugee, return migrant, guest worker or religion (e.g. Muslim are rare in the survey. In terms of ethnicity, identifying foreign residents in Finland is inconsistent, particularly as Russians and Estonians, the two largest groups, are not readily seen as foreign residents. The prevalence of answering Somalis could be considered an outcome of the maximally visible difference between Finns and Somalis. A logistic regression analysis is used to examine whether identifying resident foreigners differs according to socio-economic and educational characteristics, age, gender, region, and attitude towards the number of resident foreigners in Finland. The variables that signi? cantly in? uence the probability of answering Somalis and Russians are the respondents region, age, attitude towards the number of foreign residents in Finland, and to some extent, gender and higher education. Respondents occupational status, vocational education or income does not have a signi? cant impact on the answers. Regional differences appear to be a major factor affecting how foreigners are identi? ed, which shows that although the need to consider resident foreigners as visibly, culturally and linguistically maximally different may be a nearly universal base line for creating difference and identity, identifying foreign residents in Finland is not entirely independent of demographic realities.

    The natural petroleum hydrocarbon degrading capacity of the Archipelago Sea water in S-W Finland was studied in a microcosm experiment. Pristine and previously oil exposed sites were examined. Bacterial community fingerprinting was performed using terminal restriction fragment length polymorphism (T-RFLP) and samples from selected microcosms were sequenced. The abundance of PAH degradation genes was measured by quantitative PCR. Bacterial communities in diesel exposed microcosms diverged from control microcosms during the experiment. Gram positive PAH degradation genes dominated at both sites in situ, whereas gram negative PAH degrading genes became enriched in diesel microcosms. The dominant bacterial groups after a 14 days of diesel exposure were different depending on the sampling site, belonging to the class Actinobacteria (32%) at a pristine site and Betaproteobacteria (52%) at a previously oil exposed site. The hydrocarbon degrading bacteria in the Baltic Sea differ from those in the oceans, where most hydrocarbon degraders belong to Gammaproteobacteria. Copyright © 2013 Elsevier Ltd.

    Full Text Available Changes in landscape over a period of 50 years were analysed in a rural area of 324 ha in Central Finland. The data were digitized from aerial photographs of the National Land Survey taken in 1944, 1959, 1979 and 1991, and analysed with the IDRISI™ geographic information system (GIS. The average proportion of land in agricultural use in the sample area was 17.4%. The arable area declined from the maximum of 62.3 ha (1959 to 47.6 ha. The total length of linear landscape elements, predominantly ditch bank habitats, halved, from 876 m/ha of field (1944 to 449 m/ha by the end of the period. The average rate of loss of field boundary habitat was 9.1 m/ha/ year. At the same time, the Shannon-Weaver index of diversity of agricultural landscape elements dropped from 0.37 to 0.24. The number of field parcels declined by 29%, and the mean parcel size increased by 45%, from 1.2 ha to 1.7 ha. The index value of the fractal dimension measuring the complexity of parcel shapes also fell, from 1.88 (1959 to 1.86 (1991. The change in spatial structure reflects the intensification of farming in Finland. Biodiversity at ecosystem level has clearly declined. However, the implications for the agroecosystem and its sustainability are still unknown.

  5. Mechanical-biological waste treatment and the associated occupational hygiene in Finland

    Tolvanen, Outi K.; Haenninen, Kari I.

    2006-01-01

    A special feature of waste management in Finland has been the emphasis on the source separation of kitchen biowaste (catering waste); more than two-thirds of the Finnish population participates in this separation. Source-separated biowaste is usually treated by composting. The biowaste of about 5% of the population is handled by mechanical-biological treatment. A waste treatment plant at Mustasaari is the only plant in Finland using digestion for kitchen biowaste. For the protection of their employees, the plant owners commissioned a study on environmental factors and occupational hygiene in the plant area. During 1998-2000 the concentrations of dust, microbes and endotoxins and noise levels were investigated to identify possible problems at the plant. Three different work areas were investigated: the pre-processing and crushing hall, the bioreactor hall and the drying hall. Employees were asked about work-related health problems. Some problems with occupational hygiene were identified: concentrations of microbes and endotoxins may increase to levels harmful to health during waste crushing and in the bioreactor hall. Because employees complained of symptoms such as dry cough and rash or itching appearing once or twice a month, it is advisable to use respirator masks (class P3) during dusty working phases. The noise level in the drying hall exceeded the Finnish threshold value of 85 dBA. Qualitatively harmful factors for the health of employees are similar in all closed waste treatment plants in Finland. Quantitatively, however, the situation at the Mustasaari treatment plant is better than at some Finnish dry waste treatment plants. Therefore is reasonable to conclude that mechanical sorting, which produces a dry waste fraction for combustion and a biowaste fraction for anaerobic treatment, is in terms of occupational hygiene better for employees than combined aerobic treatment and dry waste treatment

    Impacts of peatland restoration on nutrient and carbon leaching from contrasting sites in southern Finland Tapani Sallantaus1, Markku Koskinen2, Harri Vasander2 1)Finnish Environment Institute, Biodiversity unit, Box 140, FIN-00251 Helsinki, Finland, tapani.sallantaus@ymparisto.fi 2)Department of Forest Sciences, University of Helsinki, Box 27, FIN-00014 University of Helsinki, Finland, markku.koskinen@helsinki.fi, harri.vasander@helsinki.fi Less than 20 % of the original mire area of southern Finland is still in natural state. Even many peatlands in today's nature conservation areas had been partly or totally drained before conservation. Until now, about 15000 ha of peatlands have been restored in conservation areas. Here we present data concerning changes in leaching due to restoration in two contrasting areas in southern Finland. The peatlands in Seitseminen have originally been fairly open, growing stunted pine, and unfertile, either bogs or poor fens. The responses of tree stand to drainage in the 1960s were moderate, and the tree stand before restoration was about 50 m3/ha, on average. The trees were partly harvested before filling in the ditches mainly in the years 1997-1999 . The peatlands of Nuuksio are much more fertile than those in Seitseminen, and had greatly responded to drainage, which took place already in the 1930s and 1950s. The tree stand consisted mainly of spruce and exceeded 300 m3/ha in large part of the area. The ditches were dammed in the autumn 2001 and the tree stand was left standing. Runoff water quality was monitored in three basins in both areas. To obtain the leaching rates, we used simulated runoff data obtained from the Finnish Environment Institute, Hydrological Services Division. The responses in leaching were in the same direction in both cases. However, especially when calculated per restored hectare (Table 1), the responses were much stronger in the more fertile areas of Nuuksio for organic carbon and nitrogen, but not so much

    Cutaneous complications related to permanent tattoos affect 2-30% of those patients who have tattooed their skin. Little is known about the cases of tattoo complications in Finland. The aim of this study was to conduct a retrospective review of a series of Finnish patients with cutaneous tattoo reactions. We collected cases of tattoo reactions from the Department of Dermatology at Helsinki University Central Hospital, from members of the Finnish dermatological society and from various other sources (author's private practice, tattooists, professional internet forum). We analysed the demographics, clinical presentation, diagnosis, and microscopic findings on the skin biopsies, and evaluated the therapeutic outcome. Thirty-one patients (16 men and 15 women, mean age 37.8) were included from 9 cities, mainly from Helsinki. Fifty-two percent (16/31) presented with an allergic tattoo reaction mainly against the red colour (75%, 12/16). Reactions were clinically polymorph ranging from scattered papules or nodules to complete infiltration of a colour. Lesions were itchy and sometimes painful. The reactions were lichenoid, granulomatous, pseudolymphomatous or less specific with a dermal lympho-histiocytic or plasmocytic infiltrate. Other diagnoses included tattoo blow-out (13%), melanoma within a tattoo, naevi within a tattoo (10% each), lichen planus (6%), granulomatous reaction with uveitis, sarcoidosis and dermatofibroma (3% each). Allergic tattoo reactions were mainly treated with local corticosteroid (CS) ointments, CS infiltration or surgical removal. This review is the largest series of tattoo complications in the Baltic area. It illustrates the wide spectrum of complications. Prospective, controlled therapeutic studies are necessary to assess the best treatment protocols for tattoo allergies and tattoo reaction management in general. © 2017 S. Karger AG, Basel.

  13. DFN Modeling for the Safety Case of the Final Disposal of Spent Nuclear Fuel in Olkiluoto, Finland

    Vanhanarkaus, O.

    2017-12-01

    Olkiluoto Island is a site in SW Finland chosen to host a deep geological repository for high-level nuclear waste generated by nuclear power plants of power companies TVO and Fortum. Posiva, a nuclear waste management organization, submitted a construction license application for the Olkiluoto repository to the Finnish government in 2012. A key component of the license application was an integrated geological, hydrological and biological description of the Olkiluoto site. After the safety case was reviewed in 2015 by the Radiation and Nuclear Safety Authority in Finland, Posiva was granted a construction license. Posiva is now preparing an updated safety case for the operating license application to be submitted in 2022, and an update of the discrete fracture network (DFN) model used for site characterization is part of that. The first step describing and modelling the network of fractures in the Olkiluoto bedrock was DFN model version 1 (2009), which presented an initial understanding of the relationships between rock fracturing and geology at the site and identified the important primary controls on fracturing. DFN model version 2 (2012) utilized new subsurface data from additional drillholes, tunnels and excavated underground facilities in ONKALO to better understand spatial variability of the geological controls on geological and hydrogeological fracture properties. DFN version 2 connected fracture geometric and hydraulic properties to distinct tectonic domains and to larger-scale hydraulically conductive fault zones. In the version 2 DFN model, geological and hydrogeological models were developed along separate parallel tracks. The version 3 (2017) DFN model for the Olkiluoto site integrates geological and hydrogeological elements into a single consistent model used for geological, rock mechanical, hydrogeological and hydrogeochemical studies. New elements in the version 3 DFN model include a stochastic description of fractures within Brittle Fault Zones (BFZ

  15. Introduction of a Uranium tax in Finland

    International Nuclear Information System (INIS)

    2011-01-01

    In Finland, it is possible to create a tax model on uranium that will not compromise the profitability of future power plant investments or decisively reduce climate policy incentives for carbon-free energy production. The rise in energy costs caused by the tax could be compensated by lowering the electricity tax imposed on industry. The estimates above were made by Managing Director Pasi Holm and Professor Markku Ollikainen, who, on 4 February 2011, handed over their report concerning introduction of uranium tax to Minister of Economic Affairs Mauri Pekkarinen. According to the administrators, one can deem nuclear power to include specific grounds for imposing a tax via the fact that storage of used nuclear fuel involves a (infinitesimally small) risk of accidents with irreversible effects, and that, through the EU climate policy, nuclear power companies gain extra profit 'for nothing', i.e. windfall profit. The EU Energy Tax Directive facilitates collection of uranium tax. Uranium tax, imposed as an excise tax, would target the nuclear power plants in operation as well as the Olkiluoto 3 plant, presently under construction. The amount of uranium fuel used would serve as the basis of taxation. Holm and Ollikainen introduce two tax models, adjustable in a manner that the uranium tax would yield revenues of approximately EUR 100 million a year. The companies would still keep more than half of the profit and the state, depending on the model used, would collect 43 to 45 per cent of it via the tax. In the minimum tax model, the uranium tax is 44.5 of the difference between the market price of emission allowance and the average price of 2010 (EUR 15/tonne of CO 2 ), used as the comparison price, the minimum being EUR 2/MWh. The tax would yield a minimum of EUR 67 million to the state a year. When the emission allowance price rises to EUR 30, the tax would be EUR 6.7/MWh and the state would earn revenues of EUR 223 million. In a flexible tax model, the fixed part of the

  16. EPR becomes reality at Finland's Olkiluoto 3

    International Nuclear Information System (INIS)

    2005-01-01

    The EPR is a third-generation pressurized water reactor (PWR). Its development was started in 1992 by Framatome and Siemens within a Franco-German partnership. Since 2001 this work has been continued by Framatome ANP, which was formed when the two companies merged their nuclear businesses. The French company AREVA, world market leader in nuclear technology, holds a 66% share in Framatome ANP, with Siemens owning 34%. From the very start, development of the EPR was focused on improving plant safety and economics even further. The new reactor development was jointly financed together with the leading power utilities of both countries. The first steps towards realization of an EPR nuclear power plant were taken at Olkiluoto, Finland in 2004, consisting of initial preparation of the construction site. By mid-February 2005 the local municipality - Eurajoki - had issued a construction permit, and the Finnish Government a construction license pursuant to the Finnish Nuclear Energy Act. This had been preceded by a preliminary safety assessment prepared by the Finnish Radiation and Nuclear Safety Authority (STUK) for the Finnish Ministry of Trade and Industry in which STUK verified that it did not see any safety-related issues opposing issuance of the nuclear construction license. STUK emphasized that the evolutionary design of the EPR had been further improved by AREVA compared to the previous product lines. Concreting work began this spring and the unit will start commercial operation in 2009. Construction of an EPR has also been given the political go-ahead in France. According to the utility Electricite de France (EDF) the new reactor will be built as a forerunner of a later series at the site of Flamanville in Normandy. Construction is scheduled to begin in 2007. An EPR nuclear power plant has a rated electric capacity of around 1600 MW, depending on specific site conditions. Being the product of intense bilateral cooperation the EPR combines the technological

  18. Fethiye-Burdur Fault Zone (SW Turkey): a myth?

    Fethiye Burdur Fault Zone (FBFZ) is first proposed by Dumont et al. (1979) as a sinistral strike-slip fault zone as the NE continuation of Pliny-Strabo trench in to the Anatolian Block. The fault zone supposed to accommodate at least 100 km sinistral displacement between the Menderes Massif and the Beydaǧları platform during the exhumation of the Menderes Massif, mainly during the late Miocene. Based on GPS velocities Barka and Reilinger (1997) proposed that the fault zone is still active and accommodates sinistral displacement. In order to test the presence and to unravel its kinematics we have conducted a rigorous paleomagnetic study containing more than 3000 paleomagnetic samples collected from 88 locations and 11700 fault slip data collected from 198 locations distributed evenly all over SW Anatolia spanning from Middle Miocene to Late Pliocene. The obtained rotation senses and amounts indicate slight (around 20°) counter-clockwise rotations distributed uniformly almost whole SW Anatolia and there is no change in the rotation senses and amounts on either side of the FBFZ implying no differential rotation within the zone. Additionally, the slickenside pitches and constructed paleostress configurations, along the so called FBFZ and also within the 300 km diameter of the proposed fault zone, indicated that almost all the faults, oriented parallel to subparallel to the zone, are normal in character. The fault slip measurements are also consistent with earthquake focal mechanisms suggesting active extension in the region. We have not encountered any significant strike-slip motion in the region to support presence and transcurrent nature of the FBFZ. On the contrary, the region is dominated by extensional deformation and strike-slip components are observed only on the NW-SE striking faults which are transfer faults that accommodated extension and normal motion. Therefore, we claim that the sinistral Fethiye Burdur Fault (Zone) is a myth and there is no tangible

    Full Text Available This paper describes the technological development of wells and toilets and the cultural practices related to them in two countries, South Africa and Finland, from the Middle Ages to modern times. Wells and toilets have always been linked to the well-being of humans and they still are the most common technical systems in the service of mankind. They are simple to build, but if they are constructed improperly or stop functioning properly, they may endanger the health of both humans and the environment. The solutions used for getting clean water or for disposal of excrement have always been a matter of life and death for human settlements. Located on opposite sides of the world, the climate and natural resources of South Africa and Finland are very different. However, surprisingly similar solutions, for example wind turbines to pump water, have been used in rural areas. Furthermore, urbanization and industrialization occurred in both countries at approximately the same time in the 19th century, which caused increasing environmental problems in Finnish and South African urban areas. The transition to modern water supply and waste disposal systems was a very demanding process for municipal administrations in both countries.

    A three-year project, started in 2012, "Efficient use of natural stone in the Leningrad region and South-East Finland", studies the use and durability of natural stone in the city environments in the Nordic climate and especially along the Eastern Baltic Sea coastline between Helsinki and St. Petersburg. The project is lead by the Geological Survey of Finland (GTK) and the partners in the project are Saimaa University of Applied Sciences from Finland and Federal State Unitary Enterprise "Petersburg Complex Geological Expedition" Russian together with Saint-Petersburg State University from the Russian Federation. As associates in this project are also natural stone companies from Finland, Ylämaa Group Oy and Palin Granit Oy. The project is co-funded by the European Union, the Russian Federation and the Republic of Finland through the European Neighbourhood and Partnership Instrument (ENPI). A great potential of natural stone that can be used in construction is located in the border zone between South-East Finland and the Leningrad region. Rapakivi granite from that area has been utilized for several important buildings worldwide since 18th century and the area holds still potential for future economic growth. The use of the stone particularly from this area is based on its visual expression and good properties with high durability and long life cycle that can be used as arguments in the future development. Strengthening of the knowledge of the material reserves in the area gives a long term basement for economic development. Special aim of the project is to promote the use of natural stone in the city construction, especially the use of left-over stone generated in the production. In the project the use of natural stone in larger cities from the 18th century until today including the towns St. Petersburg, Vyborg, Helsinki, Kuopio and Kotka will be reported. Also an analysis of the near future needs of natural stone (qualities and quantities) in reconstruction and

  6. A preliminary examination of adaption to climate change in Finland

    International Nuclear Information System (INIS)

    Carter, T.R.; Kankaanpaeae, S.

    2003-01-01

    The global mean surface air temperature has increased by 0.6 ± 0.2 deg C during the 20th century and by about 0.7 deg C in Finland over the same period. Most of the observed warming over the last 50 years is thought to be attributable to increases in atmospheric greenhouse gas concentrations. There is also widespread evidence (including some from Finland) that this warming has already had discernible impacts on many physical and biological systems. Projected future climate changes are expected to have significant adverse effects on natural ecosystems, biodiversity, human health, and flood risk in Finland, while beneficial effects include increased crop yields and timber production and reduced winter energy demand. Worldwide, adverse impacts are expected to fall disproportionately on poorer countries and populations. Regardless of any foreseeable reductions in emissions, some future climate change appears to be unavoidable, so society must be prepared to adapt to the inevitable consequences of climate change. Adaptation is thus a necessary complement to mitigation as a policy response to climate change, and has the potential to reduce many of the adverse impacts of climate change and to enhance beneficial impacts. However, understanding of adaptive capacity is relatively poor across all sectors in Finland, and lags behind comparable work in some other countries. In this report a number of research recommendations are suggested to redress this imbalance. (orig.)

    Hypospadias is one of the most common congenital anomalies but the etiology is not fully understood. There seem to be genetic, endocrinological, and environmental factors involved. Great geographical variation in the prevalence of hypospadias has been reported both between and within countries. We studied the determinants of geographical variation in the prevalence of hypospadias in Finland. All patients treated for hypospadias in 1970-1996 before the age of 9 years among boys born in 1970-1986 were identified in the national hospital discharge registry. Prevalence of hypospadias was calculated for each of the 355 municipalities in Finland. Demographic data were obtained from Statistics Finland. Association of the explanatory factors with prevalence of hypospadias was assessed using Poisson regression methods. The prevalence of operated hypospadias varied between provinces and between university hospital districts, from a ratio of 0.65 to a ratio of 1.01. An association between the prevalence of hypospadias and the remoteness from the closest city was observed. There was no association with level of education, social class, or occupation. The observed differences in the prevalence of operated hypospadias in Finland may have several explanations. Different levels of ascertainment and both genetic and environmental factors can not be ruled out

  12. Visions on energy production technologies for Finland up to 2030

    International Nuclear Information System (INIS)

    Kara, Mikko

    2003-01-01

    The energy sector will face major challenges in the coming decades. Global demand for primary energy is continuously increasing, as are its related environmental effects. On the other hand, the limited resources of especially oil and gas will lead to increasing price instability. Deregulation of energy markets is a challenge for the infrastructure. This deregulation is leading to restructuring of the energy market. States and owners of energy companies and energy policy decision-makers will find it difficult to play this double role. At European level and in Finland the biggest challenge is the attainment of the Kyoto target and then further reduction of greenhouse gas emissions. Renewables, nuclear power and growing imports of natural gas from Russia will play a crucial role in Finland. This presentation focuses on the development of the energy production technologies that are most important for Finland's energy supply and energy technology exports. In order to analyse the possible role of various emerging and evolving technologies in the future energy system of Finland, three scenarios has been created for a comprehensive energy system model. The model is based on a bottom-up, technology oriented representation of the energy system, including both the supply and end-use sector. Mathematically, the model is a quasi-dynamic linear optimisation model that stimulates the behaviour of energy-economic decision-making by minimising the total present value of all costs and other expenditures in the energy system during the entire time horizon under consideration.

    Full Text Available Nowadays companies concern more about how to survive and extend their own business in future in their current marketplace. However, developing and prospering a region of the country is becoming more crucial question. Successful cooperation and partnership between different sectors of economy (for instance, between companies, public and academic sectors leads to the flourishing and prosperity of the region and consequently of a country. European Commission established smart specialization platform, which is a strategic approach to economic development of a region. By defining and developing of vision, competitive advantages and strategic preferences, region will determine knowledge-based potential. The purpose of this paper is to assign and define the collaboration/relations existed, how strong these relations are and what the expectations are between 3 sectors of economy: public, academic and business. Area of carrying out this research is Ostrobothnia region, however, connections in other regions of Finland and internationally is also presented. There have been chosen 3 industrial peaks from Ostrobothnia region: Energy, Fur and Boat industrial peaks. Analysis is conducted by implementing two core methods: Sense & Respond (S&R and Sustainable Competitive Advantage (SCA. The goal of this research is also to use S&R method so as to allocate efficiently resources, and to define competitive priorities in cooperation. The main results show that the most tight collaboration and partnership is observed between companies and companies in all around Finland and internationally. While concerning other relationships, companies expect to have tighter cooperation especially in Ostrobothnia and other regions of Finland.

    Small-scale distributed energy generation is expected to play an important role in helping Finland increase its energy self-sufficiency. However, the overall strategy to date for promoting distributed energy remains unclear. It is not yet well understood which factors promote the growth of the distributed energy sector and what barriers need to be removed. In this article we present the results of a questionnaire directed at a panel of 26 experts from the distributed energy value chain and 15 semi-structured interviews with industry and non-industry representatives. We investigated, from a sociotechnical transition perspective, the possibilities and challenges of the transition to distributed energy in Finland through 2025. The results show that a shift to a prosperous future for distributed energy is possible if permit procedures, ease of grid connection, and taxation laws are improved in the electricity sector and new business concepts are introduced in the heat sector. In contrast to other European countries, the transition in Finland is expected to take place through a market-based approach favoring investment-focused measures. We conclude that incentive-based schemes alone, whatever they may be, will be insufficient to create significant growth in Finland without institutional change, removal of barriers, and the engagement of key actors. - Highlights: • We examine the possibilities and challenges of the transition to DE in Finland. • Technological niches are emerging both in the heat and electricity sector. • Business model innovation is evident only in the electricity sector. • Removing barriers and developing new business models will accelerate the transition.

    contributing to enhanced safety worldwide through international cooperation. In line with the IAEA Action Plan on Nuclear Safety, the mission reviewed the regulatory implications for Finland of the March 2011 accident at the Fukushima Daiichi Nuclear Power Station in Japan. The mission found that STUK's immediate- and longer-term response was timely and effective. Although short-term safety issues were not identified, a number of safety improvements have been initiated and STUK performed extremely well in informing the public. The IRRS team identified a number of areas where the overall performance of the regulatory system could be improved, including: - Although STUK operates in practice as an independent regulatory body, the government should strengthen the legislative framework by embedding in law the regulatory body, separate from entities having responsibilities or interests that could unduly influence its decisions; - The Finnish legislative framework should be further developed to cover authorization for facility decommissioning and the waste repository shutdowns; and - STUK can improve the effectiveness of its inspection activities by enhancing the focus of inspection on the most safety-significant areas and developing a formal qualification programme for inspectors. In its preliminary report, the IAEA team's main conclusions have been conveyed to STUK. A final report will be submitted to the Government of Finland in about three months. STUK has informed the team that the final report will be made publicly available. The IAEA encourages nations to invite a follow-up IRRS mission about two years after the mission has been completed. Background The team reviewed the legal and regulatory framework for nuclear safety and addressed all facilities regulated by STUK with the exception of the research reactor FiR 1, which STUK decided to exclude because the operator is shutting it down. This was the 44th IRRS mission conducted by the IAEA. Quick Facts - Finland has four

    The Convention on the Protection of the Marine Environment of the Baltic Sea Area signed in 1974 in Helsinki is probably the most important environmental agreement consummated in the Baltic Sea region. This article is the first study that explores the history of this agreement, also known as the Helsinki Convention, by using primary archival sources. The principal sources are the archives of the Ministry for Foreign Affairs of Finland. We examine the role of Finland in the process that led to the signing of the Helsinki Convention from the perspective of international politics. The study focuses primarily on Finnish, Swedish, and Soviet state-level parties from the end of the 1960s to 1974. We show that Cold War politics affected in several ways negotiations and contents of the Helsinki Convention. We also argue that the Soviet Union used the emerging international environmental issues as a new tool of power politics.

  3. The ‘inside’ and ‘outside’ of prisons: Carceral geography and home visits for prisoners in Finland

    Full Text Available This paper argues that the burgeoning sub-discipline of carceral geography needs to pay particular attention to context when theorising carceral space, and that the specific context of Finland offers a new and valuable perspective. Much of the work within this new area of human geography originates in or pertains to the highly incarcerative, or ‘hypercarcerative’ contexts of the US, the UK and the Russian Federation, raising questions over the transferability of theorisations of the carceral to other less carcerative, or actively ‘de-carcerative’ settings. By focussing specifically on one such setting, the low imprisonment context of Finland, this paper discusses Goffman’s ‘total institution’ thesis with reference to the system of ‘furloughs’ or home visits for prisoners. In this paper we explore the extent to which this practice destabilises the inside/outside binary of the ‘total institution’, through the notion of heterotopia.

    Full Text Available Forestry, as a large industry, has significant impacts on the quality of nature-based tourism landscapes in boreal forests. In Finland, the rapid growth of nature-based tourism has expanded outdoor recreation activities from protected areas into timber production forests; this is particularly so in northern Finland. This paper focuses on assessing balanced local net impacts of three alternative land-use scenarios, in which the level of integration between nature-based tourism (NBT and traditional forestry is varied. The study is located in northern Finland in the area between two top-rated tourist resorts, Ylläs and Levi. The results of the case study support the idea of an eligible integration between NBT and forestry, which takes into account scenic qualities of forested landscapes by restricting traditional management practices. In our case, the increased number of tourists (due to a more attractive forest environment offset the losses accrued in forestry (due to restricted forest management.

    Understanding inner structure of seismogenic faults and their ability to reactivate is particularly important in investigating the continental intraplate seismicity regime. In our study we address this problem using analysis of ambient seismic noise recorded by the temporary DAFNE array in northern Fennoscandian Shield. The main purpose of the DAFNE/FINLAND passive seismic array experiment was to characterize the present-day seismicity of the Suasselkä post-glacial fault (SPGF) that was proposed as one potential target for the DAFNE (Drilling Active Faults in Northern Europe) project. The DAFNE/FINLAND array comprised the area of about 20 to 100 km and consisted of 8 short-period and 4 broad-band 3-component autonomous seismic stations installed in the close vicinity of the fault area. The array recorded continuous seismic data during September, 2011-May, 2013. Recordings of the array have being analyzed in order to identify and locate natural earthquakes from the fault area and to discriminate them from the blasts in the Kittilä Gold Mine. As a result, we found several dozens of natural seismic events originating from the fault area, which proves that the fault is still seismically active. In order to study the inner structure of the SPGF we use cross-correlation of ambient seismic noise recorded by the array. Analysis of azimuthal distribution of noise sources demonstrated that that during the time interval under consideration the distribution of noise sources is close to the uniform one. The continuous data were processed in several steps including single station data analysis, instrument response removal and time-domain stacking. The data were used to estimate empirical Green's functions between pairs of stations in the frequency band of 0.1-1 Hz and to calculate correspondent surface wave dispersion curves. After that S-wave velocity models were obtained as a result of dispersion curves inversion using Geopsy software. The results suggest that the area of

    The goal of this study was to obtain a representative estimate on concentration of natural radionuclides in private well water and the radiation exposure from drinking water of people living outside public water supply in Finland. According to earlier studies, the number of private well users in Finland is about 10% of the population. Nonetheless, this group receives more than half of the collective radiation dose due to natural radioactivity in drinking water. In a random sampling study 2,000 persons, not using a public water supply as their drinking water according to the Population Register Centre were selected to the survey. Among subjects who gave their consent, about 500 private well users were selected in the study. Activity concentration of radon ( 222 Rn), radium ( 226 Ra), uranium ( 238 U and 234 U), lead ( 210 Pb) and polonium ( 210 Po), and mass concentration of uranium were determined from 288 drilled wells and 184 wells dug in soil. The concentrations of natural radionuclides were several times higher in drilled wells than in wells dug in soil. The average radon concentration in drilled wells was 460 Bq/l and in dug wells 50 Bq/l. The highest concentrations were found in Southern Finland, in Uusimaa region, and in South-Western Finland. Additionally, occasional high concentrations were found all over Finland. The average uranium concentration in drilled wells was 21 μg/l and in dug wells 1 μg/l. Spatial distribution of uranium was essentially similar to that of radon. The average radium concentration in drilled wells was 0.05 Bq/l and in dug wells 0.02 Bq/l. Unlike radon and uranium, the highest radium concentrations were found in coastal area. The average lead concentration in drilled wells was 0.040 Bq/l and in dug wells 0.013 Bq/l and the average polonium concentration 0.048 Bq/l and 0.007 Bq/l, respectively. Spatial distributions of lead and polonium were similar to that of radon. The average annual effective dose from natural radionuclides for

    Rossignol-Strick, M.

    In the Eastern Mediterranean sea, the climate succession of the last deglaciation is documented and dated in marine cores by the d18-O variation of foraminiferal cal- cite and pollen records. The Last Glacial Maximum is identified by a large abundance of grass pollen from a prairie-type vegetal cover with low annual precipitation in the mountainous north and east borderlands of the sea, where the pollen mainly origi- nates. During the first phase of the last deglaciation, the Bolling/Allerod chronozone, the moisture availability increases and makes possible the spread of a deciduous for- est, as shown by the increasing pollen abundance of the deciduous oak. The cold and arid Younger Dryas is identified by a reversal to semi-desert conditions, with the in- crease of sage-brush (Artemisia) and the saline-tolerant Chenopodiaceae. The climate of the earliest Holocene is Optimum for at least 3000 years (9000-6000yr BP), with the largest spread of the deciduous forest at low-middle elevations signalling wet sum- mers and of the Pistacia woodland at low elevations signalling mild, no-frost winters. This is the time when the most recent sapropel deposited in the eastern Mediterranean under anoxic bottom conditions generated by a surface lid of lower salinity due to the concomitant largest floods of the Nile River fed by the strongest African monsoon rains in the Ethiopian Highlands. In SW Asia, the pollen records of lakes and marshes have been correlated with those of the marine cores, thereby obtaining a robust time-frame. In that area, the archaeo- logical data of human settlements are independently dated by 14C. Thus the archaeo- logical succession can be securely set against the well-dated climatic succession. The Late Palaeolithic populations of SW Asia were wandering hunter-gatherers in the prairies of the Last Glacial Maximum, where they already collected wild wheat, barley and fruit. With the Bolling/Allerod wetter and warmer climate, they began to settle in

    The seven different extractions are used to evaluate and compare the element concentrations and solubility both dried/sieved and fresh mineral soil samples OLFEH914254, OL-FEH917258, OL-FIP10 and OL-FIP10 and humus sample OL-FIP10 taken from the Olkiluoto Island in 2010. The study focuses on the key elements assigned top priority in the biosphere assessments: Cl, Cs, I, Mo, Nb, Ni, Se and Sr. The priority grouping of radionuclides is based on their expected relevance for long-term safety using a simple screening evaluation applied on the calculations cases analysed in the biosphere analyses in the safety case studies and the cases to be analysed from the radionuclide transport model. The extractions included: total, aqua regia, NH 4 Ac (pH 4.5) and water leach extractions. The sequential extractions consisted of: exchangeable, acid-soluble/bound to carbonates, bound to Fe-Mn oxides, bound to organic matter and residual fractions, in addition, separate aqua regia extraction was included. Molybdenum, niobium and selenium concentrations were higher in aqua regia extraction than in the total extraction. Aqua regia extractions were analysed by using different methods in two different laboratories, and thus the results are not completely comparable for the most of the elements. In addition, dry and organic matter, pH, cation exchange capacity and grain size distribution were measured. The pH values measured in the deionised water were on average 0.5 units higher than pH values extracted by 0.01 M CaCl 2 . The CEC was significantly higher in the humus sample than in the mineral soil samples. In modelling migration of elements in ecosystems, especially radionuclides, it is used distribution coefficients (K d values) and concentration ratios (CR), both including a component of concentration in the solids. Solubility of different solid elements varies widely depending the used methods and extracts. (orig.)

    Full Text Available Discussing how the concept of social pedagogy has been used in Finland and Sweden, this paper provides a historical and systemic comparison of policies and practices of social pedagogy in these two countries. The main aim is to identify and explain the main similarities and differences between the Finnish and Swedish national trajectories of social pedagogical thinking and action. In the first phase of the analysis, country-specific features of social pedagogy were described paying attention to historical and structural aspects. In the second phase, these descriptions were compared in a dialogue between the au- thors, one from Finland and the other from Sweden. The dialogue-based comparison was targeted to ex- plain the identified similar and different features of social pedagogical policies and practices. The explanation was based on historical and systemic considerations, especially those of historical development, research activities, theory buildings, methodologies and techniques, professionalization and the practice fields, and the future prospects of social pedagogy.The analysis showed that the historical roots and theoretical foundations of social pedagogical think- ing and action are very similar in Finland and Sweden but the position of social pedagogy  as an academic discipline  as well as a field of practice is partly different. Since social pedagogy has not been acknowl- edged as an academic discipline in Sweden, its outlook as a field of practice is on shaky ground, while in Finland the future of social pedagogy as an academic discipline  is uncertain because the social-peda- gogical know-how based on academic education is not well known and has not found general acceptance in the field’s practice.The analysis showed that the historical roots and theoretical foundations of social pedagogical thinking and action are very similar in Finland and Sweden but the position of social pedagogy as an academic discipline as well as a

    2016-01-01

    Full Text Available Needle pathogens of larch (Larix spp. in the Nordic countries are under-studied. Their incidence in Finland tends to be low and local, and this may be a function of enemy release, since species of larch were introduced to the region. Here, the ecology and incidence of larch needle pathogens and the abiotic factors that also affect larch in northern Finland are reviewed. Field observations and related laboratory analyses during the past 35 years have mainly been obtained near the Kivalo Research Area within the Arctic Circle, Finnish Lapland. The relatively recent introduction of Hypodermella laricis is a primary focus. This pathogen is not only new to Nordic countries, but can cause severe outbreaks, defoliation and crown-thinning in the canopies of all ages of most planted larch species worldwide. Symptoms of H. laricis clearly differ from those of Mycosphaerella laricina; the latter has affected Larix sibirica at high latitudes for decades. The effects of Meria laricis, Lophodermium laricinum, various rust fungi, and wind and frost are also discussed.

    A new national daily snowfall record was measured in Finland on 8 January 2016 when it snowed 73 cm (31 mm as liquid water) in less than a day in Merikarvia on the western coast of Finland. The area of the most intense snowfall was very small, which is common in convective precipitation. In this work we used hourly weather radar images to identify the sea-effect snowfall case and to qualitatively estimate the performance of HARMONIE, a non-hydrostatic convection-permitting weather prediction model, in simulating the spatial and temporal evolution of the snowbands. The model simulation, including data assimilation, was run at 2.5 km horizontal resolution and 65 levels in vertical. HARMONIE was found to capture the overall sea-effect snowfall situation quite well, as both the timing and the location of the most intense snowstorm were properly simulated. Based on our preliminary analysis, the snowband case was triggered by atmospheric instability above the mostly ice-free sea and a low-level convergence zone almost perpendicular to the coastline. The simulated convective available potential energy (CAPE) reached a value of 87 J kg-1 near the site of the observed snowfall record.

    Sediment microbial activity and its relationship with the main environmental factors and pollutants were examined in the coastal area of the eastern Gulf of Finland, Baltic Sea. The activity of two common oxidoreductase enzymes: dehydrogenase (DA) and catalase (CA) varied significantly between 13 study sites. In the Neva Bay the highest microbial activities (DA: 2.64 mg TFF (10 g- 1) day- 1, CA: 6.29 mg H2O2 g- 1) were recorded, while in the outer estuary the minimum values of dehydrogenase and catalase were measured. DA, CA, and abundances of culturable heterotrophic bacteria (CHB) were positively correlated with each other, while biomass of green opportunistic algae was independent of both microbial activities and CHB. Enzymatic activity was found to be strongly positively correlated with sediment particle size and organic matter content, but unrelated to the other studied environmental parameters (temperature, pH, and salinity). Principal components analysis (PCA), controlling for environmental variables, supported direct effects of metal and oil contamination on sediment microbial activity. Also it had shown the similar patterns for algal biomass and metals. Our results suggest that copper and hydrocarbons are the main anthropogenic variables influencing enzyme distribution along the eastern Gulf of Finland coastline.

    The importance of core competencies (CC) and their relationship to core interventions in clinical practice guidelines on schizophrenia (CPGS), and the abilities to master these competencies were studied among registered nurses (RN) and practical mental nurses (PMN) in a forensic psychiatric setting. Data were collected from RNs, PMNs, and managers of all five forensic psychiatric facilities in Finland. The research material was obtained by using a 360-degree feedback method. The response rate was 68% (N = 428). The differences between the nurse groups were statistically significant (p ≤ 0.05) regarding the importance of and ability to master the following CCs: (1) pharmacotherapy, (2) knowledge in forensic psychiatry and violent behavior, (3) the treatment of violent patients, (4) processing patient's and own emotion, and (5) need-adapted treatment of the patient. Overall, RNs exceeded PMNs in mastering the CCs, however the principles of the CPGS were not achieved within the current resources in Finland. In summary, RNs, rather than PMNs, should be recruited for work in forensic psychiatric nursing, although a considerable amount of specific training would still be required to achieve competence. Implications of our research indicate that all nurses working in this area need to receive further education in forensic psychiatry and in forensic psychiatric nursing. © 2011 International Association of Forensic Nurses.

    Full Text Available The concern for the state of global freshwater reservoirs has increased due to deterioration of the water quality during the last decades. This has prompted monitoring and restoration efforts such as the European Water Framework Directive and the national-scale 2nd-investigation and monitoring of the water quality, water volume and biota resources in China. The challenge so far has been the determination of the natural state (reference conditions of freshwater ecosystems. We used the sediment archives of five lakes and one brackish water embayment in Finland and China to assess the impact of selected variables of climatology, hydrology, nutrients, and changes in human population on these ecosystems during the last few centuries. The study sites represent catchment areas with varying land use. Despite the long distance between the sites and their different land-use characteristics, the direction and timing of changes during the last few centuries are well comparable between the high latitudes of Finland and the mid-low latitudes of China. This study reinforces the sensitivity of aquatic ecosystems to environmental change and underlines the usefulness of the palaeolimnological approach as a tool for determining reference conditions.

    A hydrostratigraphical approach to support environmentally safe siting of a mining waste facility at Rautuvaara, Finland Based on the construction of a detailed sedimentological model, hydrostratigraphy and local groundwater/surface water flows, this paper analyses the Niesajoki river valley...... of the valley. The thickness and complexity of sediments varied across the study area. To the E/SE of the valley, sediments are thick (~40 m), and more complex., In contrast the S/W/NW of the area, sediments are thinner (~10 m) and more simple. Groundwater is found to flow towards the centre of the valley...... and along its axis, where a bedrock controlled divide forms two groundwater basins. Based on the results of this research, it is suggested that any future expansion of the tailings facility should be restricted to the western and southern side of the valley, where waters are more manageable....

    1987-02-01

    The goal of the study is to give an overview of the whole diversified research field of fire technology and its problems. For this reason the research subjects have been grouped so that the responsibilities of different authorities, the legislation and specifications, various fields of technology, areas of industry, and groups of products could all be found as clearly as possible. The field has been divided into nine sub-areas. They are: general grounds, fire physics and chemistry, structural fire prevention, textiles and furnishings, devices for heating and other use, detection, fire fighting and rescue, quality control, and special problems. The sub-areas have been divided into 34 main subjects and these, excluding those of special problems, further into as many as 117 subject groups. Characteristics and problems of the sub-areas and the main subjects have been described. The subject groups have been characterized by key words and concepts which outline the projects. No concrete research projects and programs have, however, been directly suggested because their extent and contents depend essentially on financing and other available resources.

    Ochreous precipitate and water samples were collected from the surroundings of seven closed sulphide mines in Finland. In the Hammaslahti Zn-Cu-Au mine, Otravaara pyrite mine and Paroistenjaervi Cu-W-As mine, the collection was repeated in different seasons to study mineralogical and geochemical variations of precipitates. The sampling was done in 1999-2002 from the ditches and drainage ponds of the tailings and waste rock piles that are susceptible to seasonal changes. Mineralogy of the precipitates was evaluated by X-ray diffraction (XRD) and infrared spectroscopy (IR), and precipitate geochemistry was examined by selective extractions. Schwertmannite (Fe 8 O 8 (OH) 6 SO 4 ) was the most typical Fe hydroxide mineral found. Goethite was almost as common as schwertmannite, was often poorly ordered, and contained up to 10 wt.% of SO 4 . Goethite and schwertmannite were commonly found as mixtures, and they occurred in similar pH and SO 4 concentrations. Ferrihydrite (nominally Fe 5 HO 8 . 4H 2 O) was typically found in areas not influenced by acid mine drainage, and also in acid mine waters with high organic matter or As content. Jarosite (KFe 3 (SO 4 ) 2 (OH) 6 ) was found only in one site. In addition, some gypsum (CaSO 4 . 2H 2 O) and aluminous sulphate precipitates (presumably basaluminite, Al 4 (SO 4 )(OH) 10 . 5H 2 O) were identified. Selective extractions showed that acid extracts Fe tot /S tot -ratios of schwertmannite and goethite samples were similar, but the ratio of oxalate-extractable to total Fe, Fe ox /Fe tot , of goethite samples were lower than those of the schwertmannite samples. Only Al, Si and As were bound to precipitates in substantial amounts, up to several wt.%. In schwertmannites and goethites, Al, Cu, Co, Mn and Zn were mostly structural, substituting for Fe in an Fe oxyhydroxide structure or bound to surface adsorption sites in pores limited by diffusion. In ferrihydrites, heavy metals were also partly bound in adsorbed form dissolving in

  3. When Finland was lost. Background, Course of Events and Reactions.

    Full Text Available Since 1809 the loss of Finland has been discussed in different ways in Swedish history research. In the early 20th century the burst of the state was seen in a nationalistic perspective. It was said that the people in Sweden, or the “public opinion”, with despair and in a “nationalistic trauma” received the news bulletins from the peace agreement in Fredrikshamn 1809, which was interpreted the worst defeat ever in Swedish history. Nowadays researchers argue whether the loss of Finland really was seen as a nationalistic trauma in the early 19th century. The article first summarises the background of the war and the most important war episodes and then discusses the apprehension of a Sweden in national chock after the burst of the state.

    We investigate the determinants of suicide in Finland using annual data for consumption and suicides from 1860 to 2010. Instead of using some ad hoc measures of cyclical movements of the economy, we build our analysis on a more solid economic theory. A key feature is the habit persistence in preferences, which provides a way to measure individual well-being and predict suicide. We estimate time series of habit levels and develop an indicator (the hardship index) to describe the economic hardship of consumers. The higher the level of the index, the worse off consumers are. As a rational response to such a bad situation, some consumers might commit suicide. We employ the autoregressive distributed lags cointegration method and find that our index works well in explaining the long-term behavior of people committing suicide in Finland.

    2002-01-01

    STUK (Radiation and Nuclear Safety Authority) collected the number of radiological examinations in Finland in 2000. The work was based on a decree of the ministry of social affairs and health on the medical use of radiation. The work was done in cooperation with the Finnish work group of nomenclature of radiological examinations and procedures and professor Seppo Soimakallio. In 2000, ca. 4.1 million x-ray examinations were made in Finland. In 1984 and in 1995, the numbers were ca. 4.6 million and 4.2 million, respectively, indicating that the total number of x-ray examinations has remained nearly unaltered. The proportions of conventional x-ray examinations, computed tomography examinations, angiographic and interventional procedures were ca. 93.5 %, 5.0 %, 0.9 % and 0.6 %, respectively. The reported number of ultrasound examinations was ca. 0.5 million. The reported number of MRI examinations was ca. 0.1 million.

  6. Fertility and Public Policies - Evidence from Norway and Finland

    Directory of Open Access Journals (Sweden)

    2004-05-01

    Full Text Available The relatively high and rising fertility rates of Nordic countries in the late 1980s and early 1990s sparked a renewed research interest in the possible pronatalistic effects of generous family policy programs. Several studies have addressed this issue, but few have tried to model policy effects explicitly. The existing evidence so far is mainly from Sweden, where policy indicators have been incorporated in economic fertility models that also control for female wages. This paper complements previous Swedish analyses with evidence from Norway and Finland. The results corroborate earlier findings of a negative effect of female wages. There are also indications of a positive policy impact, as maternity leave extensions are estimated to raise birth rates, although mainly higher parity births and mainly in Finland.

    2011-08-15

    This paper describes initial findings from a study concerning the practices and development needs of Human Factors Engineering (HFE) in Finland. HFE is increasing in importance as the Radiation and Nuclear Safety Authority Finland (STUK) is renewing the regulatory guidelines and the intention is to include requirements concerning HFE. The motivation for the paper is to discover how HFE is conducted currently in order to envision what should be aimed at when modifying requirements for design practices. In an interview with STUK it was discovered that current HFE practices encompass mainly activities related to control room modifications and as such namely verification and validation of new designs. The adoption of the entire HFE process in design and modification projects requires changes that include better integration of technical and Human Factors Engineering approaches. Boundary objects that mediate between different design disciplines are needed in order to enforce the stronger integration. Concept of operations (CONOPS) is suggested as a such boundary object.

    1990-01-01

    Finland has achieved some remarkable achievements in nuclear power production. Existing four plants have some of the best operating records in the world - high capacity factors, low occupational doses and short refuelling outages. Although public opinion was strongly turned against nuclear power after Chernobyl accident, and no decisions for new nuclear plants can be made before next elections in 1991, the nuclear option is still open. Utility companies are maintaining readiness to start new construction immediately after a positive political decision is made. One important component of the good operation history of the Finnish nuclear power plants is connected to the continuous research, development, modification and upgrading work, which is proceeding in Finland. In the following a short description is given on recent activities related to the I and C-systems of the nuclear power plants. (author). 2 tabs

    Continuous population aging has raised international policy interest in promoting active aging (AA). AA theoretical models have been defined from a biomedical or a psychosocial perspective. These models may be expanded including components suggested by lay individuals. This paper aims to study the correlates of AA in three European countries, namely, Spain, Poland, and Finland using four different definitions of AA. The EU COURAGE in Europe project was a cross-sectional general adult population survey conducted in a representative sample of the noninstitutionalized population of Finland, Poland, and Spain. Participants (10,800) lived in the community. This analysis focuses on individuals aged 50 years old and over (7,987). Four definitions (two biomedical, one psychosocial, and a complete definition including biomedical, psychosocial, and external variables) of AA were analyzed. Differences in AA were found for country, age, education, and occupation. Finland scored consistently the highest in AA followed by Spain and Poland. Younger age was associated with higher AA. Higher education and occupation was associated with AA. Being married or cohabiting was associated with better AA compared to being widowed or separated in most definitions. Gender and urbanicity were not associated with AA, with few exceptions. Men scored higher in AA only in Spain, whereas there was no gender association in the other two countries. Being widowed was only associated with lower AA in Poland and not being married was associated with lower AA in Poland and Finland but not Spain. Associations with education, marital status, and occupation suggest that these factors are the most important components of AA. These association patterns, however, seem to vary across the three countries. Actions to promote AA in these countries may be addressed at reducing inequalities in occupation and education or directly tackling the components of AA lacking in each country.

    Estlander, A.; Otterstroem, T.

    1994-01-01

    The goal of the project is to develop a method for estimation of external costs of energy production in Finland. The purpose of the method is to take into account all the most important impacts on health, materials and the environment. The study will assess environmental effects of emissions from Finnish energy production on people and the environment locally (population centres), nationally (Finland) and globally. The different energy production forms to be included in the study are heat and electric energy generated with coal, natural gas, fuel oil and peat (not industry's energy production). Local and national environmental impact assessment is carried out within the Finnish borders. The economic influence of emissions (in particular greenhouse gases) originating outside Finland but with global impact will also be assessed, as far as Finland is concerned. When studying the amounts of emissions the whole fuel chain is taken into account: production, processing or transport, storage in the different stages of the chain of use, and end use. The main components under review are SO 2 , NO x , CO 2 , H x C y , CO, particulates and a couple of heavy metals. In addition. the study considers ozone (O 3 ), which is formed in the atmosphere. The primary monetary valuation method used is the indirect monetarization. which is based on dose-response functions and the use of both market prices and willingness-to-pay assessments. The method to be developed during the project for monetary valuation of effects caused by emissions on health, materials and the environment can be utilized in further monetarization studies. The results of the work can used to assess the profitability of energy production plants and energy companies from the economic point of view

  19. Urban form and greenhouse gas emissions in Finland

    International Nuclear Information System (INIS)

    Harmaajaervi, Irmeli

    2003-01-01

    Finland's regional form is becoming more concentrated, while urban sprawl is causing growth centres to become fragmented. The effects caused by these changes on greenhouse gas emissions were studied up to the year 2010, when, in accordance with the Kyoto protocol, Finland's greenhouse gas emissions should be reduced to the 1990 level. The urban form affects especially transportation inside regions, the potential to utilise district heating and the need for infrastructure. By preventing urban sprawl and by encouraging teleworking and some lifestyle changes, it would be possible to reduce annual transportation emissions by the year 2010 by 1.1 million tonnes CO 2 eq., i.e. 27%, the emissions from residential and service buildings by 1.1 million tonnes CO 2 eq., i.e. 5%, and the emissions from municipal infrastructure by 0.1 million tonnes CO 2 eq., i.e. 6%. Altogether, it is possible to reduce the greenhouse gas emissions by 2.3 million tonnes, which amounts to 15% of Finland's target for emissions reductions in 2010. If the target-oriented scenario is realised, the subsequent decrease of emissions would accelerate. To stop urban sprawl, measures are required in planning, land use and housing policy as well as in transportation and tax policies. Additionally, more needs to be done in regard to co-operation, interaction and information dissemination. This paper introduces a report which estimates, for the first time, the effects caused by changes in the regional and urban forms on the levels of greenhouse gas emissions in Finland

  2. Snow bands over the Gulf of Finland in wintertime

    Jordi Mazon

    2015-01-01

    Full Text Available Large shore-parallel, quasi-stationary snow bands are occasionally observed over the Gulf of Finland during wintertime when the sea is not frozen. On the basis of Weather Research and Forecasting mesoscale model experiments and radar observations of snow bands formed in January 2006 and February 2012, we show that their dynamics share common characteristics: (1 the sea gulf that produces the known lake effect, (2 cold easterly large-scale flow along the gulf and (3 a cold local flow from the two near and opposite coastlines of Estonia and Finland in the form of two land-breeze cells which collide offshore. The associated fronts, which have strong rising motions, are maintained by the convergence of the land-breeze cells. In addition to these factors, the concave shape of the coast in the eastern part of the Gulf of Finland promotes offshore convergence and the formation of several secondary bands of precipitation that are adjacent to the eastern part of the main band. When the easterlies turn to southerlies, horizontal convective rolls appear over the sea. The Estonian land breeze is enhanced while the cold air remains stagnant inland over the Finnish coast, acting as an orographic barrier lifting the marine air mass upwards. Consequently, a line of convective precipitation composed of several cells is formed along the Finnish coast. In both events, the simulations also show two low-level jets generated by the combined effects of the land-breeze cells and baroclinicity over the coast of Finland and Estonia.

    2010-07-15

    The Metsaeteho study investigated how logging residue chips, stump wood chips, and chips from small sized thinning wood and large-sized (rotten) roundwood used by heating and power plants were produced in Finland in 2008. Almost all the major forest chip suppliers in Finland were involved in the study. The total volume of forest chips supplied in 2008 by these suppliers was 6.5 TWh. The study was implemented by conducting an e-mail questionnaire survey and telephone interviews. Research data was collected in March-May 2009. The majority of the logging residue chips and chips from small-sized thinning wood were produced using the roadside chipping supply chain in Finland in 2008. The chipping at plant supply chain was also significant in the production of logging residue chips. 70% of all stump wood chips consumed were comminuted at the plant and 29% at terminals. The role of the terminal chipping supply chain was also significant in the production of chips from logging residues and small-sized wood chips. When producing chips from large-sized (rotten) roundwood, nearly a half of chips were comminuted at plants and more than 40% at terminals

    The Metsaeteho study investigated how logging residue chips, stump wood chips, and chips from small-diameter thinning wood and large-sized (rotten) roundwood used by heating and power plants were produced in Finland in 2009. Almost all the major forest chip suppliers in Finland were involved in the study. The total volume of forest chips supplied in 2009 by these suppliers was 8,4 TWh. The study was implemented by conducting an e-mail questionnaire survey and telephone interviews. Research data was collected from March-May, 2010. The majority of the logging residue chips and chips from small-diameter thinning wood were produced using the roadside chipping supply system in Finland in 2009. The chipping at plant supply system was also significant in the production of logging residue chips. Nearly 70 % of all stump wood chips consumed were comminuted at the plant and 28 % at terminals. The role of the terminal chipping supply system was also significant in the production of chips from logging residues and small-diameter wood chips. When producing chips from large-sized (rotten) roundwood, similarly roughly 70 % of chips were comminuted at plants and 23 % at terminals. (orig.)

    In liberalized electricity markets, suppliers are offering several kinds of voluntary green electricity products marketed as environmentally friendly. This paper focuses on the development of these voluntary markets at household level in the UK, Germany and Finland. Since there are already existing renewable energy policies regulating and encouraging the use of renewable energy, it is important to consider whether voluntary products offer real additional benefits above these policies. Problems such as double counting or re-marketing hydropower produced in existing plants are identified. According to our study, the demand varies between countries: in Germany the number of green electricity customers has increased and is also higher than in the UK or Finland. Typically the average additional cost to consumer from buying green electricity product instead of standard electricity product is in the range of 0-5% in all studied countries, although the level of price premium depends on several factors like electricity consumption. Case study of Finland and literature show that the impacts of green energy are not solely environmental. Renewable energy can benefit local public policy.

    After the Chernobyl accident at no stage did the radiation situation in Finland require actual protective action, such as taking shelter indoors or in civil defence shelters. Civil defence plans for emergency situations include a warning level at 200 μSv/h (population has to stay indoors) and an alarm level at 2000 μSv/h (populaiton has to seek shelter immediately). Both levels are 'at the latest' levels, given as guidance in case regional or local authorities have to make the decision. The highest confirmed gamma radiation reading in Finland was 5 μSv/h. During the first days of the Chernobyl fail-out it also became evident that no large scale restrictions for use of foodstuffs were needed in the Nordic countries. Various mitigating actions were adopted in the days and weeks following Chernobyl, but mostly in the form of recommendations. The situation in Finland can serve to explain the various types of mitigating actions considered, how they were adopted, and to some extent give information on how efficient and how expensive the mitigating actions were

    Energy policy measures aim to increase energy production from forest chips in Finland to 10 TWh by year 2010. However, on the regional level production differences are large, and the regional estimates of the potential base of raw materials for the production of forest chips are heterogeneous. In order to analyse the validity of the above target, two methods are proposed to derive forecasts for region-level energy production from forest chips in Finland in the years 2008-2014. The plant-level data from 2003-2007 gives a starting point for a detailed statistical analysis of present and future region-level forest chip production. Observed 2008 regional levels are above the estimated prediction 95% confidence intervals based on aggregation of plant-level time averages. A simple time trend model with fixed-region effects provides accurate forecasts for the years 2008-2014. Forest chip production forecast confidence intervals cover almost all regions for the 2008 levels and the estimates of potential production levels for 2014. The forecast confidence intervals are also derived with re-sampling methods, i.e. with bootstrap methods, to obtain more reliable results. Results confirm that a general materials shortfall is not expected in the near future for forest chip energy production in Finland.

    Plant growth inhibitory alkaloids were isolated from the extract of mesquite [Prosopis juliflora (Sw.) DC.] leaves. Their chemical structures were established by ESI-MS, 1H and 13C NMR spectra analysis. The I50 value (concentration required for 50% inhibition of control) for root growth of cress (Lepidium sativum L.) seedlings was 400 microM for 3''''-oxo-juliprosopine, 500 microM for secojuliprosopinal, and 100 microM for a (1:1) mixture of 3-oxo-juliprosine and 3'-oxo-juliprosine, respectively. On the other hand, the minimum concentration exhibiting inhibitory effect on shoot growth of cress seedlings was 10 microM for 3''''-oxo-juliprosopine, 100 microM for secojuliprosopinal, and 1 microM for a (1:1) mixture of 3-oxo-juliprosine and 3'-oxo-juliprosine, respectively. Among these compounds, a (1:1) mixture of 3-oxo-juliprosine and 3'-oxo-juliprosine exhibited the strongest inhibitory effect on the growth of cress seedlings.

    The Geological Survey of Norway participated in the exercise RESUME95 (Rapid Environmental Surveying Using Mobile Equipment 95) in Finland, during August 1995. The purpose of the exercise was to 1) test preparedness in the Nordic countries for accidents involving the release and dispersal of radioactive material, 2) compare results from the different teams participating in the exercise, 3) establish routines for the exchange of data and 4) investigate the possibility of international assistance in the event of nuclear accidents. The Geological Survey of Norway carried out a survey over three test areas (area I, II and III). All three areas were contaminated with man made radionuclides in the days following the Chernobyl nuclear reactor accident. The Cesium-137 contamination level was reported to be about 50 kBq/m{sup 2} in area I, and this area was used for calibration. In area II mapping of Cesium-137 ground concentration was carried out. Detection of hidden artificial radiation sources were the main purpose in area III. This report describes the exercise - RESUME95, field operations, calibration, mapping of Cesium-137 ground concentration and detection of hidden point sources. Results are presented as colour maps.

  4. Dynamics of positional warfare malaria: Finland and Korea compared.

    A sudden outbreak of vivax malaria among Finnish troops in SE-Finland and along the front line in Hanko peninsula in the southwest occurred in 1941 during World War II. The common explanation has been an invasion of infective Anopheles mosquitoes from the Russian troops crossing the front line between Finland and Soviet Union. A revised explanation is presented based on recent studies of Finnish malaria. The exact start of the epidemic and the phenology of malaria cases among the Finnish soldiers were reanalyzed. The results were compared with the declining malaria in Finland. A comparison with a corresponding situation starting in the 1990's in Korea was performed. The malaria cases occurred in July in 1941 when it was by far too early for infective mosquitoes to be present. The first Anopheles mosquitoes hatched at about the same time as the first malaria cases were observed among the Finnish soldiers. It takes about 3-6 weeks for the completion of the sporogony in Finland. The new explanation is that soldiers in war conditions were suddenly exposed to uninfected mosquitoes and those who still were carriers of hypnozoites developed relapses triggered by these mosquitoes. It is estimated that about 0.5% of the Finnish population still were carriers of hypnozoites in the 1940's. A corresponding outbreak of vivax malaria in Korea in the 1990's is similarly interpreted as relapses from activated hypnozoites among Korean soldiers. The significance of the mosquito induced relapses is emphasized by two benefits for the Plasmodium. There is a synchronous increase of gametocytes when new mosquitoes emerge. It also enables meiotic recombination between different strains of the Plasmodium. The malaria peak during the positional warfare in the 1940's was a short outbreak during the last phase of declining indigenous malaria in Finland. The activation of hypnozoites among a large number of soldiers and subsequent medication contributed to diminishing the reservoir of malaria

    Ground penetrating radar (GPR) has been used in Finland since 1980's for civil engineering applications. First applications in this field were road surveys and dam inspections. Common GPR applications in road surveys include the thickness evaluation of the pavement, subgrade soil evaluation and evaluation of the soil moisture and frost susceptibility. Since the 1990's, GPR has been used in combination with other non-destructive testing (NDT) methods in road surveys. Recently, more GPR applications have been adopted, such as evaluating bridges, tunnels, railways and concrete elements. Nowadays, compared with other countries GPR is relatively widely used in Finland for road surveys. Quite many companies, universities and research centers in Finland have their own GPR equipment and are involved in the teaching and research of the GPR method. However, further research and promotion of the GPR techniques are still needed since GPR could be used more routinely. GPR has been used to evaluate the air void content of asphalt pavements for years. Air void content is an important quality measure of pavement condition for both the new and old asphalt pavements. The first Finnish guideline was released in 1999 for the method. Air void content is obtained from the GPR data by measuring the dielectric value as continuous record. To obtain air void content data, few pavement cores must be taken for calibration. Accuracy of the method is however questioned because there are other factors that affect the dielectric value of the asphalt layer, in addition to the air void content. Therefore, a research project is currently carried out at Aalto University in Finland. The overall objective is to investigate if the existing GPR technique used in Finland is accurate enough to be used as QC/QA tool in assessing the compaction of asphalt pavements. The project is funded by the Finnish Transport Agency. Further research interests at Aalto University include developing new microwave asphalt

    The eastern Gulf of Finland - Lake Ladoga region - is at the peripheral part of the Fennoscandian post-glacial uplift. We compared different modeling results for this region with observations, including our revision of geomorphological traces of paleo shorelevel. As in many parts of the general Baltic-White Sea bedrock lowland at the margin of the Fennoscandian Shield, the bedrock landscape was modified by glaciers, but it was also the major controlling factor for the history of glacial grows and decays. First-order landforms of this segment are: Lake Ladoga-Lake Ilmen lowland, Lembolovo High of the Karelic Isthmus and Neva-Gulf of Finland lowland. The range of the bedrock topography is close to 350 m. The landforms reflect different glacial behavior during stadials, with fast movement and strong erosion in northern Ladoga, but passive motion and accumulation around Lembolovo High. The differences influenced the ice sheet and deglaciation history. The shore level displacements in this area are slightly different than westwards in the Baltic area; the shoreline tilts are usually lower in southern-central part of the eastern Gulf of Finland-lake Ladoga region. For example, the shoreline tilts at 11 600 BP in the Baltic Ice Lake in the south-east range from 0.55 to 0.31 m/km. The slope of the Ancylus shoreline varies from 0.12 to 0.18 m/km, increasing to almost the double in the north-western area. Similarly, the Littorina shore level is tilted only 0.08 m/km, rising to 0.14 m/km in the north-west. We have used this data in our high resolution modeling involving glacial isostasy, hydro isostasy, sediment isostasy, and gravity field changes. The mopdeling is based on Earth rheology model with a low-viscosity asthenosphere of thickness less than 150 km and viscosity less than 7.0x10**19 Pa s above a mantle of viscosity 10**21 Pa s, and an effective elastic lithosphere thickness of 30-40 km (flexural rigidity 10**24 Nm). The specific uplift features in the area are

    Full Text Available Abstract Background The spread of vector-borne diseases to new regions has become a global threat due to climate change, increasing traffic, and movement of people and animals. Dirofilaria repens, the canine subcutaneous filarioid nematode, has expanded its distribution range northward during the last decades. The northernmost European locations, where the parasite life-cycle has been confirmed, are Estonia and the Novgorod Region in Russia. Results Herein, we describe an autochthonous D. repens infection in a Finnish woman. We also present two cases of D. repens infection in imported dogs indicating the life-cycle in the Russian Vyborg and St Petersburg areas, close to the Finnish border. Conclusions The most obvious limiting factor of the northern distribution of D. repens is the summer temperature, due to the temperature-dependent development of larvae in vectors. With continuing climate change, further spread of D. repens in Fennoscandia can be expected.

    Objective To investigate the role of N-myc downstream regulated gene 2 (NDRG2) gene in the proliferation, migration and apoptosis of rectal cancer cells. Methods Human rectal cancer SW480 cells were cultured and transfected with pCDNA3.1-NDRG2 and empty vector (SW480-Ve). SW480 cells were set as a control group. Cell proliferation was detected in SW480 cells, SW480-Ve cells and SW480-NDRG2 cells by MTT assay; cell migration distance in the three groups at 24, 48, 72 hours was tested by wound healing assay; apoptosis rate was determined in the three groups at 48 hours by flow cytometry; the expressions of Bax, caspase-3, Bcl-2 proteins in the three groups were examined by Western blotting. Results After the cells were cultured for 7 days, cell survival rate in SW480-NDRG2 group was significantly lower than that in SW480 cells and SW480-Ve cells; the cell survival rate decreased gradually with the prolongation of the culture time; and it had no significant difference between SW480-Ve group and SW480 group. Cell migration distance in SW480-NDRG2 group was significantly lower than that in SW480-Ve cells and SW480 cells, and it had also no significant difference between SW480-Ve cells and SW480 cells. The apoptosis rate in SW480-NDRG2 group was significantly higher than that in SW480 group and SW480-Ve group, and SW480 cells and SW480-Ve cells had no significant difference in the rate. The expressions of Bax and caspase-3 proteins in SW480-NDRG2 group were significantly higher than those in SW480 cells and SW480-Ve cells; Bcl-2 protein expression was significantly lower in SW480-NDRG2 group than in SW480 cells and SW480-Ve cells; and the expressions of Bax, caspase-3 and Bcl-2 proteins were not significantly different between SW480 cells and SW480-Ve cells. Conclusion Overexpression of NDRG2 can inhibit the proliferation, reduce cell migration, and promote cell apoptosis by regulating the expressions of Bcl-2, Bax and caspase-3 proteins in SW480 cells.

    The ground and 1s core hole state molecular wave functions of CH 4 , NH 3 , H 2 O, and HF obtained from Xa--SW calculations using the touching spheres (TS) and overlapping spheres (OS) approximations are used to calculate the intensity of shakeup satellites observed in their ls core level photoelectron spectra. The sudden approximation was assumed in the calculation. In case of TS Xa--SW wave functions, the one electron overlap integral inside the intersphere was calculated via Green's theorem. For OS Xa--SW wave functions, the integration over the awkwardly shaped intersphere region was circumvented by distributing the intersphere charge into the atomic spheres according to the charge partition scheme suggested by Case and Karplus. Our results show that there are no significant differences between the shakeup energies calculated from the TS and OS approximations. However, shakeup intensities calculated from TS Xa--SW wave functions are more reliable and in better numerical agreement with experiment

    2017-07-01

    The dosimetric properties of the recently developed SW557 phantom have been investigated by comparison with those of the existing SW457 phantom in megavoltage photon beams. The electron fluence ratio φ pl w , and chamber ionization ratio k pl , of water to SW457 and water to SW557 for 4-15MV photons were calculated as a function of depth using Monte Carlo simulations, and compared with measured values. Values of φ pl w for SW457 were in the range of 1.004-1.014 for 4MV, and 1.014-1.018 for 15MV photons. The φ pl w for SW557 ranged from 1.005 to 1.008 for 4MV and from 1.010 to 1.015 for 15MV photons and the variation of φ pl w with depth for each beam energy was within ±0.5%. Values of k pl were obtained with a PTW 30013 Farmer-type ionization chamber. The k pl for SW457 ranged from 0.997 to 1.011 for 4-15MV photons. Values of k pl for SW557 were almost unity for 4 and 6MV photons, while in the case of 10 and 15MV photons they were less than 1.006, excepting the build-up region. The measured and calculated k pl values of water to SW557 were in the range of 0.997-1.002 and 1.000-1.006, respectively, for 4-15MV photons, at a depth of 10cm with a source-to-axis distance of 100cm. The measured and calculated k pl values were in agreement within their uncertainty ranges. As a water-equivalent phantom, SW557 can be used with a dosimetric difference within±0.6%, for 4-15MV photons, and is more water-equivalent than SW457 in megavoltage photon beams.

    Full Text Available A coastal scenery assessment was carried out at 50 sites along the 910 km long Andalusia coast (SW Spain using a checklist of 26 natural and human parameters, parameter weighting matrices, and fuzzy logic. A scenic classification was utilised that can rate sites as Class I (natural areas of great scenic beauty to Class V (urbanised areas of poor scenic interest, but, for this study, only natural sites of great scenic value were investigated; 41 sites were included in Class I, 9 in Class II and, apart from four, all of the sites were under some feature of protection—managed by the Andalusia Environmental Agency (RENPA, in Spanish. Sites belong to the Natural Park Cabo de Gata-Nijar (24% of sites, the Natural Park of Gibraltar Strait (18%, the Natural Place Acantilado de Maro-Cerro Gordo (12%, and the Natural and National parks of Doñana (8%. Results obtained by means of scenic evaluation constitute a sound scientific basis for any envisaged management plan for investigated coastal areas preservation/conservation and responsible future developments, especially for natural protected areas, which represent the most attractive coastal tourist destinations. With respect to natural parameters, excellent scenic values appeared to be linked to the geological setting and the presence of mountainous landscapes related to the Betic Chain. Human parameters usually show good scores because null or extremely reduced human impacts are recorded, but, at places, conflicts arose between conservation and recreational activities because visitors are often interested in beach activities more so than ecotourism. Low scores of human parameters were often related to litter presence or the unsuitable emplacement of utilities, such as informative panels, litter bins, etc.

  17. Environmental isotope application to investigate the hydrogeological aquifers of Yarmouk basin SW of Syria

    Al-Charideh, A.

    2002-01-01

    Environmental isotopic variations have been used to investigate the source of recharge and age in the basaltic and deep limestone aquifers system in the Yarmouk basin, SW of Syria. Isotopic results show that recharge of basaltic aquifer is directly related to infiltration of rainwater from high and transitional zones. However, the homogeneity noted of stable and radioactive isotopes values (δ 18 O= -5.58± 0.25%, 14 C=46.2± 4.45 % pmc) in Laja plateau and central zone, confirm the mechanism of common recharge and critical role of this plateau in absorbing great amount of precipitation. In addition these values indicate, to a high rate mixing taking place in this plateau and the central zone. In the Kahiel area, the groundwater is of recent age as shown from the high values of 14 C activity ( 14 C= 66.3 ± 5.3 % pcm) accompanied by enriched 18 O (δ 18 O=-4.7±0.22 %). The recharge of groundwater is related to the leakage of water from dams and drainage network. The tectonic setting in this area constitutes an additional factor in increasing this recharge. Netpath model was used to determine the age of groundwater. the age of groundwater in the basaltic aquifer is generally modern and reaches 2000 y BP in discharge area. Preliminary conclusion of deep limestone aquifer, indicate that its groundwater occur under high piezometric pressure. The salinity is less than 1g/L and the temperature water varied between 35 to 45 degreed centigrade. The low 14 C activities in deep groundwater suggest pleistocene and holocene recharge, although their stable isotopes values indicate recharge by modern meteoric precipitation. The corrected age of this groundwater determined by Netpath model indicate that this age fall between recent water in recharge area and 20 Ky BP. (author)

  18. Energy requirements for new buildings in Finland

    2012-06-15

    Buildings account for circa 40% of the total energy use in Europe [1] and for about 36% of the EU's total CO{sub 2} emissions [2], including the existing energy conservation in buildings [3]. Key features of the Finnish energy policy are improved energy efficiency and increased use of renewable energy sources. To achieve a sustainable shift in the energy system, a target set by the authorities, both energy savings and increased use of low-pollution energy sources are therefore priority areas. Building low-energy buildings is in accordance with the declared national aim of reducing energy use and thus reducing CO{sub 2} emissions. The main motivation in renewing building codes for new buildings was to build more energy efficiently, encourage the use the most efficient energy sources and to enhance the use of renewable energy sources. In addition the aim was to give more freedom to fi nd the real optimal solutions for energy efficiency by optimising all aspects including the building architecture and different systems with demand controls. However, in order to ensure the good quality of buildings certain minimum requirements for structure U-values are given. (orig.)

    Diana Cave is located within the town limits of Baile Herculane (SW Romania) and develops as a 14 m long, westward oriented, unique passage guided by the Diana fault [1]. At the far end of the cave, the thermo-mineral Diana Spring wells forth. In the early 1970s a mine gallery that intersected the cave was created to drain the water into a pumping station and the original cave passage was somewhat altered and reinforced with concrete. Today the concrete and the silty limestone cave walls are heavily corroded by H2SO4 outgassing from the hot water (ca. 50°C) and display abundant gypsum crusts, soggy aggregates of native S, and a variety of more exotic sulfates. Among them, a mineral that has been previously identified in caves only in connection to volcanic activity, either as thermal springs or fumaroles [2]: tamarugite [NaAl(SO4)26H2O]. It was [3] that first mentioned the occurrence of this Na and Al sulfate in Diana Cave, our research aiming to give a detailed description of this mineral, its paragenesis, and mechanisms of precipitation. Recently, tamarugite has also been identified in a sulfuric acid cave from Greece [4]. Along with powder X-ray diffractions coupled with Rietveld refinement, scanning electron microscope, and electron probe micro-analysis, δ18O and δ34S compositions of the sulfate mineral as well as precipitates from the water were analyzed to identify and better constrain the genesis of this rare sulfate. Regrettably, the crystal size of our specimens is inappropriate for identification by means of single crystal X-ray diffraction. Physical and chemical parameters of Diana Spring were as well measured on several occasions. Geochemical analysis suggests that the minute, white tamarugite flakes precipitated in Diana Cave as a result of the interactions between the thermo-mineral water or water vapor and the original limestone bedrock and concrete that blankets the mine gallery.

    The current study is a new approach to vegetation mapping in Iran using remote sensing (RS) and the geographic information system (GIS). One of the most important problems in remote sensing of desert vegetation is that the reflectance from soil and rocks is often much greater than that of sparse vegetation and this makes it difficult to separate out the vegetation signal (Gates et al. 1965); and there is spectral variability within shrubs of the same species (Duncant et al., 1993). These prop...

    Earthquakes and submarine landslides are recurrent and widespread manifestations of fault activity offshore SW Iberia. The present work tests the effects of sea-level rise on offshore fault systems using Coulomb stress change calculations across the Alentejo margin. Large-scale faults capable of generating large earthquakes and tsunamis in the region, especially NE-SW trending thrusts and WNW-ESE trending dextral strike-slip faults imaged at basement depths, are either blocked or unaffected by flexural effects related to sea-level changes. Large-magnitude earthquakes occurring along these structures may, therefore, be less frequent during periods of sea-level rise. In contrast, sea-level rise promotes shallow fault ruptures within the sedimentary sequence along the continental slope and upper rise within distances of failures may either increase (if triggered by shallow fault ruptures) or decrease (if triggered by deep fault ruptures) as a result of sea-level rise. Moreover, observations of slope failures affecting the area of the Sines contourite drift highlight the role of sediment properties as preconditioning factors in this region.

    Background: Organotin compounds (OTCs) are a large class of synthetic chemicals with widely varying properties. Due to their potential adverse health effects, their use has been restricted in many countries. Humans are exposed to OTCs mostly through fish consumption. Objectives: The aim of this study was to describe OTC exposure through fish consumption and to assess the associated potential health risks in a Finnish population. Methods: An extensive sampling of Finnish domestic fish was carried out in the Baltic Sea and freshwater areas in 2005-2007. In addition, samples of imported seafood were collected in 2008. The chemical analysis was performed in an accredited testing laboratory during 2005-2008. Average daily intake of the sum of dibutyltin (DBT), tributyltin (TBT), triphenyltin (TPhT) and dioctyltin (DOT) ({Sigma}OTCs) for the Finnish population was calculated on the basis of the measured concentrations and fish consumption rates. Results: The average daily intake of {Sigma}OTCs through fish consumption was 3.2 ng/kg bw day{sup -1}, which is 1.3% from the Tolerable Daily Intake (TDI) of 250 ng/kg bw day{sup -1} set by the European Food Safety Authority. In total, domestic wild fish accounted for 61% of the {Sigma}OTC intake, while the intake through domestic farmed fish was 4.0% and the intake through imported fish was 35%. The most important species were domestic perch and imported salmon and rainbow trout. Conclusions: The Finnish consumers are not likely to exceed the threshold level for adverse health effects due to OTC intake through fish consumption.

    Periodic surveys of patient and population doses are important because of the large contribution of x-ray diagnostics to the artificial population dose. Measured entrance surface doses and dose-area products are the main quantities used for monitoring patient doses in hospitals, and most population dose studies have been derived from these quantities and from the frequences of x-ray examinations. This study is based on the radiation, exposure geometry, and patient parameters recorded by experienced radiographers and postgraduated students. The software used in the work (ODS-60 of Rados Technology) suits the determination of effective and organ doses from such detailed data using a human-like patient phantom which can be adapted for sex and size. The program, together with the very detailed input data, made it possible to determine organ equivalent and effective doses for complicated dynamic x-ray examinations and interventions in more detail than in previous studies. Collective organ and effective doses were derived for 50 examination types. The annual collective dose from diagnostic x-ray examinations in 1994 was 0.5 mSv per capita in Finland. The five groups of examinations or examinations that had greatest contributions to the collective dose were CT, barium enema: double contrast, lumbar spine, carotid angiography, and intestinal transit. Together they represented for about 60 % of the total dose. The highest dose-area products (about 2000 Gy cm{sup 2}) were obtained from certain angiographic and interventional examinations. A literature survey showed that Finland patient doses are at the same average level as in other countries of a high standard of health care. (orig.). 125 refs.

    1988-07-01

    The phenomenon of migmatization was studied in Precambrian metavolcanic gneisses of calc-alkaline chemistry, outcropping along a prograde amphibolite/granulite facies transition in the West Uusimaa Complex of SW Finland. This paper discusses one of the studied gneiss levels (a garnet-bearing Qtz/Plag/Ksp/Bio-gneiss) which was observed to transsect the metamorphic isograd pattern at almost right angle. The gneiss was studied for structures, whole-rock chemistry (major, trace and REE), mineral content, microtextures, plagioclase anorthite content and fluid inclusions. Data concerning the latter four subjects are presented. Migmatization proved to: (1) have occurred parallel to compositional banding of the rocks; (2) have produced identical leucosome/melanosome/mesosome mineral parageneses; (3) have initiated feldspar/garnet-poikiloblasthesis (and occasionally biotite porphyroblasthesis) in leucosome, and biotite-/garnet-poikiloblasthesis in melanosome; (4) have caused entrapment of unstrained quartz blebs carrying isolated (primary) two-phase pure H 2O fluid inclusions of unique filling degree range in the above-mentioned feldspar- and garnet-poikiloblasts; (5) have occurred post-D 1/pre-D 2, synchronous to amphibolitefacies metamorphism, in the subsolidus regime; (6) have been affected by D 2 in the way of localized mylonitization of the melanosome, and quartz migration (exudation) from adjacent mesosome into leucosome; and (7) have had some control by the biotite content of the original compositionally banded rock. Initial leucosome formation appears to have been controlled by the pre-leucosome biotite content: the recalculated modal biotite content of the leucosome/melanosome combination conspicuously is in the range of 5-20 vol.% of biotite. Final extent of the leucosome shows on its turn a marked correlation with mesosome modal biotite content. Because leucosomes occur carrying a recalculated modal biotite content equalling adjacent mesosome biotite content, a

    New zircon U-Pb data, along with the data reported in the literature, reveal five phases of magmatic activity in the Tengchong Terrane since the Early Paleozoic with spatial and temporal variations summarized as: Cambrian-Ordovician (500-460 Ma) to the eastern, minor Triassic (245-206 Ma) in the eastern and western, abundant Early Cretaceous (131-114 Ma) in the eastern, extensive Late Cretaceous (77-65 Ma) in the central, and Paleocene-Eocene (65-49 Ma) in the central and western Tengchong Terrane, in which the Cretaceous-Eocene magmatism was migrated from east to west (Xu et al., 2012). The increased zircon eHf(t) of the Early Cretaceous granitoids from -12.3 to -1.4 at ca. 131-122 Ma to -4.6 to +7.1 at ca. 122-114 Ma identified for the first time in this study and the magmatic flare-up at ca. 53 Ma in the central and western Tengchong Terrane (Wang et al., 2014, Ma et al., 2015) indicate the increased contributions from mantle- or juvenile crust-derived components. The spatial and temporal variations and changing magmatic compositions with time in the Tengchong Terrane closely resemble the Lhasa Terrane in southern Tibet. Such similarities, together with the data of stratigraphy and paleobiogeography (Zhang et al., 2013), enable us to propose that the Tengchong Terrane in SW Yunnan is most likely linked with the Lhasa Terrane in southern Tibet, both of which experience similar tectonomagmatic histories since the Early Paleozoic.

    The NW-trending Denizli basin of the SW Turkey is one of the neotectonic grabens in the Aegean extensional province. It is bounded by normal faults on both southern and northern margins. The basin is filled by Neogene and Quaternary terrestrial deposits. Late Miocene- Late Pliocene aged Kolankaya formation crops out along the NW trending Karakova uplift in the Denizli basin. It is a typical fluviolacustrine succession that thickens and coarsens upward, comprising poorly consolidated sand, gravelly sand, siltstone and marl. Various soft-sediment deformation structures occur in the formation, especially in fine- to medium grained sands, silts and marls: load structures, flame structures, clastic dikes (sand and gravely-sand dike), disturbed layers, laminated convolute beds, slumps and synsedimentary faulting. The deformation mechanism and driving force for the soft-sediment deformation are related essentially to gravitational instability, dewatering, liquefaction-liquidization, and brittle deformation. Field data and the wide lateral extent of the structures as well as regional geological data show that most of the deformation is related to seismicity and the structures are interpreted as seismites. The existence of seismites in the Kolankaya Formation is evidence for continuing tectonic activity in the study area during the Neogene and is consistent with the occurrence of the paleoearthquakes of magnitude >5.

  11. Scale dependence of biotic homogenisation by urbanisation: a comparison of urban bird communities between central Argentina and northern Finland

    Leveau Lucas M.

    2017-12-01

    Full Text Available Recent studies showed contrasting results about the homogenising force of urbanisation on bird community composition at large and regional scales. We studied whether urbanisation promotes the homogenisation of wintering bird communities and if this varies when comparing towns located within a specific region and towns located in two different biomes of two countries. We used both similarity indices based on the presence/absence data and the abundance data in comparing communities. Processes governing bird community dissimilarity between urbanisation levels were examined with the partitioning of Sörensen index in species turnover and nestedness. We made bird surveys in town centres and suburban habitats of three cities located in the Pampean region of Argentina and in the boreal region of Finland using a single-visit study plot method. Rarefacted species richness did not differ amongst the town centres between the countries, but it was higher in the suburban areas of Argentina than in Finland. At the country-level comparison, we found a higher similarity amongst the town centres than amongst the suburban areas; whereas at the regional comparison, similarity between town centres was comparable to the similarity between suburban areas. The use of an abundance-based index produced a higher similarity between town centre communities of both countries than when using a presence-based index. The dissimilarity between habitats in Argentina was related to nestedness and to species turnover in Finland. Our results indicate that urban-based biotic homogenisation of bird communities is dependent on the scale used, being more evident when comparing cities of different biomes where the same and abundant bird species, such as sparrows and doves, dominate. At the regional scale, quite a high beta-diversity can still be found within urban habitats. Processes of community dissimilarity between urban habitats may differ according to the regional pool of species

    The main goal of the surveillance of environmental radioactivity is to be always aware of levels of artificial radiation in the environment to which the public is exposed. Another goal is to detect all remarkable changes in levels of environmental radiation and radioactivity. Compliance with the basic safety standards laid down for protection of health of the general public against dangers arising from ionising radiation can be ensured with environmental radiation surveillance. Running of surveillance programmes on continuous basis also maintains and develops competence and readiness to respond to radiological emergencies. Surveillance of environmental radiation contains surveillance of artificial radiation and artificial radioactive elements in the environment. Natural radiation and natural radioactive elements are not associated with the surveillance programme, although the greater part of the public exposure to radiation is caused by natural radiation. Exposure to natural radiation is controlled separately if there is reason to suspect that natural radioactive elements cause unusual high exposure to the public (e.g. indoor radon and natural radionuclides in drinking water). Surveillance of environmental radioactivity in Finland is one of the official obligations of the Radiation and Nuclear Safety Authority (STUK). This obligation is based on the national and the European Communities' legislation. The Finnish radiation protection legislation appoints STUK as the national authority responsible for surveillance of environmental radioactivity, and the Euratom Treaty assumes continuous monitoring of levels of radioactivity in the air, water and soil in the Member States. In Finland, also the Finnish Meteorological Institute (FMI) and the Defence Forces are monitoring environmental radiation at their own stations. This report summarises the results of environmental radiation surveillance in 2004. The report also contains some comparisons with results from the

    An airborne gamma ray survey was conducted for the Scottish Office Environment Department of coastal and inland parts of SW Scotland to define existing background levels, to locate features worthy of further attention, and to demonstrate the emergency response capabilities of radiometric methods. Coastal areas were surveyed with 500 m line spacing. Inland areas were specified to 2 km line spacing, however it was possible to achieve 1 km line spacing in the majority of the inland zone. The radiometric maps show clearly the distributions of each individual nuclide and indicate the contribution which individual localised features make to the overall gamma ray dose rate. Naturally occurring nuclides reflect the underlying geological and geomorphological contexts of the landscapes. The main granite intrusions, most notably at Cairnsmore of Fleet, the Loch Doon Granodiorite, Glencairn of Carsphairn, the Dalbeattie granite, and Criffel Pluton are readily visible in 40 K, 214 Bi and 208 Tl maps, and control their local radiation environments. A number of areas of enhanced 214 Bi, which may reflect radon potential, were noted. A transient radon associated 214 Bi signal was observed on the west of the Wigtown peninsular during the survey. Examination of spectral data in the vicinity Dundrennan has confirmed that there is no evidence of widespread terrestrial contamination arising from the use of depleted uranium projectiles on the range. The 137 Cs map indicates the environmental distribution of this nuclide in considerable detail. Levels of 137 Cs range from approximately 2 kBq m -2 , a level consistent with global weapons' testing fallout, from 2-40 kBq m -2 on terrestrial sites affected by deposition from the Chernobyl accident, and from 40 kBq m -2 to over 200 kBq m -2 on tide washed pastures which have accumulated marine sediments from the Irish sea.

    This study has been conducted on Mansuri onshore oilfield located in Dezful Embayment, south-west Iran. One of the hydrocarbon-bearing formations is a Oligo-Miocene Asmari formation—the most prolific Iranian reservoir rock. Like many other oilfields in the area, the trap in this field is deemed structural (anticline), formed during the collision of the Arabian plate with the Iranian plate and the folding of Neotethys deposits with a NW–SE trend. This study integrates three different quantitative studies from geology, geophysics and petrophysics disciplines to quantitate ‘the qualitative study of seismic facies analysis based on trace shapes and 3D multi-attribute clustering’. First, stratigraphic sequences and seismic detectable facies were derived at one well location using the available high resolution core facies analysis and depositional environment assessment reports. Paleo and petrophysical logs from other wells were subsequently used for the extrapolation of stratigraphic sequences interpreted at the first well. Utilizing lithology discrimination obtained by wire-line log interpretation, facies were extrapolated to all wells in the area. Seismic 3D attribute analysis and seismic facies classification established a 3D facies volume accordingly, which was finally calibrated to geological facies at well locations. The ultimate extracted facies-guided geobody shows that good reservoir-quality channel sands have accumulated with NW/SE elongation at the ridge of the structure. As a result, this type of geometry has created a stratigraphic/structural hydrocarbon trap in this oilfield. Moreover, seismic facies analysis shows that buried channels do not parallel the predominant Arabian plate-originated channels (with SW–NE trends) in SW Zagros and are locally swerved in this area.

    In Finland, there are two nuclear power plants with four reactors totalling about 2 200 MWe. The oldest reactor has been operating just over ten years. In the Finnish power supply the share of nuclear power makes up one third. The optimum would be about 40%. Based on energy and nuclear attitude surveys showed that these issues are not independent in the society. Quite the opposite, the nuclear attitudes especially are tightly connected to general views like the pessimism toward the future, the credibility of large institutions, or politics, the acceptability of continuous economic growth, etc. The role of technical or economic facts, we engineers love, is found to be small, too. To change people's nuclear attitude one should be able to influence all the complex issues related to nuclear power. In theory, this is possible by ads. In that case the campaigning ought to be huge, it should last for years, and still would have basic question marks. The first question is how credible people see ads, in general, and, especially, in case of highly disputed and societal issues. Although there have been some educational ad campaigns in Finland, nuclear campaign would be a step to the unknown. Knowing that the nuclear attitudes are tightly connected to very many and quite stable societal views, and seeing the basic difficulties with ads, it is clear to me that there is no other way of promoting nuclear energy than a long and continuous public debate involving. Referring to the nuclear attitude survey results in Finland, advertising is not the solution to win the public confidence. Nuclear industry must be active in other ways than promoting nuclear power by advertising. This was the Finnish opinion. The nuclear issue is national in the sense that no country can copy models from other countries without carefully considering the local circumstances. So, in other countries there may be situations where other kinds of actions are called for

  17. Strategies and costs for reducing CO2 emissions in Finland

    Lehtilae, A.; Pirilae, P.

    1993-01-01

    In this study cost-efficient measures for the abatement of energy-related CO 2 emissions in Finland are analyzed, and the direct costs of such measures are estimated. The time frame considered is the period up to the year 2010. Furthermore, the probable impacts of an energy/CO 2 -tax on the Finnish energy system are worked out, and an attempt is made to assess the effectiveness of a tax scheme as an economic instrument for achieving CO 2 emission targets. The primary methodological tool in the analyses has been the model of the Finnish energy system developed at the Technical Research Centre of Finland (VTT) within the project. The model facilitates the search for cost-efficient emission control strategies over a period of several decades. Structural and technological changes in the energy system, e.g. fuel and technology substitution, new technologies, efficiency improvements, and energy-saving measures have been allowed for in the model. The results of the analyses show that achieving the target of returning the CO 2 emissions to the 1990 level by the year 2000 would be very difficult and costly in Finland. In the case of a nuclear moratorium it would be reasonable to delay the target by ten years. Even in the delayed cases achieving the target would require extensive structural changes and substantial energy-saving measures in the absence of additional nuclear energy. Coal use would have to be severely restricted, whereas the use of biomass and natural gas should be more than doubled compared to the 1990 levels. According to the results, a CO 2 tax would clearly be a more efficient instrument than a tax based on the energy content of a fuel

    The project aimed at studying the concept of nuclear safety culture and the Nordic nuclear branch safety culture. The project also aimed at looking how the power companies and the regulators view the current responsibilities and role of subcontractors in the Nordic nuclear safety culture as well as to inspect the special demands for safety culture in subcontracting chains. Interview data was collected in Sweden (n = 14) and Finland (n = 16) during 2009. Interviewees represented the major actors in the nuclear field (regulators, power companies, expert organizations, waste management organizations). Results gave insight into the nature and evaluation of safety culture in the nuclear industry. Results illustrated that there is a wide variety of views on matters that are considered important for nuclear safety within the Nordic nuclear community. However, the interviewees considered quite uniformly such psychological states as motivation, mindfulness, sense of control, understanding of hazards and sense of responsibility as important for nuclear safety. Results also gave insight into the characteristics of Nordic nuclear culture. Various differences in safety cultures in Finland and Sweden were uncovered. In addition to the differences, historical reasons for the development of the nuclear safety cultures in Finland and Sweden were pointed out. Finally, results gave implications that on the one hand subcontractors can bring new ideas and improvements to the plants' practices, but on the other hand the assurance of necessary safety attitudes and competence of the subcontracting companies and their employees is considered as a challenge. The report concludes that a good safety culture requires a deep and wide understanding of nuclear safety including the various accident mechanisms of the power plants as well as a willingness to continuously develop one's competence and understanding. An effective and resilient nuclear safety culture has to foster a constant

    The explosion at the Chernobyl nuclear power plant caused radioactive fallout in Finland in April-May 1986. The fallout was unevenly distributed geographically, and accordingly, the country was divided into 3 fallout zones. Whole-body radioactivity measurements of randomly chosen persons showed that the regional differences prevailed throughout the following 2 years. Data for legal abortions, registered congenital malformations as well as preterm births and stillbirths of malformed children were collected. The corresponding expected figures were obtained from statistics for 1984 and 1985. No differences in the expected/observed rates of the above parameters were detected

    The study deals with sources of indoor radon in Finland, seasonal variations in radon concentration, the effect of house construction and ventilation and also with the radiation dose from indoor radon and terrestrial gamma radiation. The results are based on radon measurements in approximately 4000 dwellings and on air exchange measurements in 250 dwellings as well as on model calculations. The results confirm that convective soil air flow is by far the most important source of indoor radon in Finnish low-rise residential housing. (97 refs., 61 figs., 30 tabs.).

    The movement to integrate special education students into normal school classes started to develop in Finland in the 1960s. At the same time, the number of students labeled "special" in the Finnish comprehensive school system exploded from 2% to 17% of all school children. Presently, 84% of all special education placements are part-time placements. Special schools and special classes comprise 15% of all special education placements, while full inclusion is only 1% of all special education placements. Some factors affecting the current integration of special students and the development of integration are discussed.

    Abstract The aim of the study is to investigate the level of work–family inter-ference (WFI) for part-time nurses in Norway and Finland. Part-time work is usually cited as a desirable way in which to facilitate work and family harmony. However, the opportunity to work part-time in professions may be associated with greater difficulties and challenges than commonly presumed. Part-time professionals are often stigmatized as being less committed to work and report fewer job rewards than colleagu...

    Full Text Available AIMS – The principles of free trade and free circulation of services within the European Union have created pressures to make the strictly controlled European gambling markets more open. According to the Court of Justice of the European Union, restrictions on gambling are only allowed if they are justified in admissible terms of consumer protection, prevention of criminal activity and protection of public order. This study compares the gambling laws of two European societies, France and Finland, to analyse how their legal frames of gambling have been adjusted to these principles.

    Full Text Available We contribute to the entrepreneurial intentions literature by applying the theory of planned behaviour and resource-based views to the model of active entrepreneurs’ intention to develop their pluriactive usinesses. Using our 2012 survey data from farm firms in Finland, we address the limited focus on active ntrepreneurs and their intentions to develop on-going income-generating, off-farm related business activities. We found that attitudinal proxy antecedents such as innovation, cooperation and growth for pluriactivity differ for active and non-active entrepreneurs and with respect to the entrepreneurs’ age and production line and innovation behaviour.

    framework. Spatial scales proved to be a black box for regional strategies in Finland. Regional strategic programmes use a similar language that ignores the spatial variations of their locations. Clusters and regional innovation systems should be considered as parts of vertical and horizontal interlinkages...... within the economy and not as individual islands of organizational proximities in isolated contexts. It is argued here that an imprecise understanding of the innovation systems and cluster approaches, both conceptually and practically, has led to some ambiguity, resulting in the use of these terms...

  14. Lithological indicators of loess sedimentation of SW Poland

    Full Text Available High-resolution grain-size investigations were carried out in two SW Polish loess sections: Biały Kościół (Niemcza-Strzelin Hills and Zaprężyn (Trzebnica Hills. Each sequence was sampled by using the same methodology and samples were taken at 5 centimeters intervals. The particle size distribution was obtained with a Mastersizer 2000 laser, used for diffraction methods. From the obtained results the basic parameters and grain size indicators were calculated: Mz, Grain Size Index ratio, U-ratio and the percentage content of clay ( 63 μm. Both loess-soil sequences are composed of interfluve and slope loess facies and consist of five litho-pedostratigraphic units developed during the Late Pleistocene and Holocene: two loess units L1LL1, L1LL2 and three polygenetic fossil soils sets S0, S1 and L1SS1. The distance between these two profiles is about 60 km. Zaprężyn, as a section located more to the north, has almost no lower younger loess and higher level of weathering which could be related to proximity of this site to the Ice Sheet margin. The climate here was more extreme and harsh. What is more, the difference in development of soil L1SS1 can be observed: while in Biały Kościół pedogenesis process was slower and less disturbed than in Zaprężyn. The upper part of L1SS1 in Biały Kościół was deformed by gelifluction, frost heave and other periglacial processes. Mz indicator by the grain-size distribution in these sediments reflects subtle variations in the climatic system. Moreover, in Zaprężyn the content of sand fraction is higher than in Biały Kościół what can be the evidence of short episodes of strong winds during cold period of sedimentation. The aim of this paper is to compare two loess profiles by their stratigraphical and lithological similarities which are result of climate conditions and features of surrounding environment.

    Ferrybox measurements have been carried out between Tallinn and Helsinki in the Gulf of Finland (Baltic Sea) on a regular basis since 1997. The system measures autonomously water temperature, salinity, chlorophyll a fluorescence and turbidity and takes water samples for further analyses at a predefined time interval. We aimed to show how the Ferrybox technology could be used to study the coastal upwelling events in the Gulf of Finland. Based on the introduced upwelling index and related criteria, 33 coastal upwelling events were identified in May-September 2007-2013. The number of events, as well as the frequency of their occurrence and intensity expressed as a sum of daily average temperature deviations in the 20 km wide coastal area, were almost equal near the northern and southern coasts. Nevertheless, the wind impulse, which was needed to generate upwelling events of similar intensity, differed between the northern and southern coastal areas. It is suggested that the general thermohaline structure adapted to the prevailing forcing and the estuarine character of the basin weaken the upwelling created by the westerly to southwesterly (up-estuary) winds and strengthen the upwelling created by the easterly to northeasterly (down-estuary) winds. Two types of upwelling events were identified - one characterized by a strong temperature front and the other revealing gradual decrease in temperature from the open sea to the coastal area, with maximum temperature deviation close to the shore.

  16. Indoor radon and risk of lung cancer: an epidemiological study in Finland

    The main aim of the present study was to establish whether high radon concentrations in dwellings in Finland had increased the risk of lung cancer. Previous studies had shown an association between the α-active radon daughters and elevated lung cancer risk among miners. Convincing evidence of the risk among the general population exposed to radon indoors was, however, lacking. A descriptive analysis was first conducted in an area in southern Finland with high indoor radon exposure. In 18 rural municipalities this analysis yielded no significant correlation between the average radon exposure and incidence of male lung cancer. A case-control study within a cohort of the same rural population was then designed. The data included 238 male cases of lung cancer diagnosed in 1980-85 and 434 controls (390 smokers and 44 nonsmokers) from the male population. Radon exposure was measured, when possible, in all the dwellings occupied by a case or control in 1950-1975. Measurements were available for the total 25-year period, or for a proportion of it, for 164 cases and 334 controls; for the rest only estimates were available. In spite of the fact that the controls were mainly selected among smokers, the amount smoked still appeared to be the most important lung cancer risk factor in the data, the risk increasing linearly with the quantity of cigarettes smoked in a lifetime. The risk of lung cancer was not associated with the radon exposure level when the whole data were studied. In heavy smokers, however, a positive though not significant, effect on the risk from radon exposure was found. In the range of uncertainty the findings do not conflict with most of those observed among miners or the general population so far. (orig.)

  17. Sustainability and meanings of farm-based bioenergy production in rural Finland

    2013-06-01

    Rural bioenergy production has accrued interest in recent years. EU pressure for climate change abatement and energy political concerns regarding the availability of fossil fuels, have increased bioenergy production objectives in Finland. In addition, rural regions in Finland have encountered structural changes following EU inclusion, including an emergent interest in auxiliary production lines of which bioenergy production is an example. Local bioenergy production has the potential to increase rural sustainability and provide a model for sustainable rural development and energy production. Focusing on the recent emergence of small-scale farm-related bioenergy production: heat provision from wood fuels and biogas and biodiesel production, this study aims to discover if and how farm-based bioenergy production contributes to sustainable rural development. The study derives from the field of rural studies and evaluates sustainable rural development via the concepts of multifunctionality, embeddedness, ecological modernization and sustainable livelihoods, with a particular focus on social sustainability. The empirical portion of the study is comprised of thematic qualitative interviews of bioenergy producing farmers, and on newspaper and periodical article material. The results demonstrate how rural small-scale bioenergy production can have important positive developmental effects that ameliorate and sustain livelihoods in remote areas. This occurs via the multifunctional benefits of bioenergy production to the producers and local communities. The positive effects include social, economical and environmental aspects and rural bioenergy production can present traits of sustainable rural development, predominantly manifested in the social aspects of increased capabilities and reinforced social networks. There are, however, important differences between the examined production models. As an example of achieving sustainable rural development and livelihoods, heat

    Lessons learned: • In Finland the most important result of the CB self-evaluation was the process itself. Commitment to this work and results by the experts and organizations are very important. • There should be a broad cooperation in the national capacity building work. • Complicated queries end in thin catch - also endless patience is needed. • All definitions should be agreed and the rules should be clear (plans of the organizations). Quality takes time. • Reserve enough time and resources. In the Finnish case the national effort forced MEE to leave important international projects aside. • It pays to be active with media also during the Self-Assessment

    In the work of selecting at the areas, heed has been taken of international geological recommendations, which have been adapted to local conditions prevailing in this country. At the present stage, the studies are largely based on the available information about the bedrock of Finland, as contained in, for example, geological maps, various geophysical maps covering the country as a whole and the maps of ore deposits and indications as well as of groundwater areas. The regional investigations of the structure of the Finnish bedrock has taken as its point of departure the study of satellite photos. These pictures best show the mosaiclike block structure of the Finnish bedrock, where the fracture zones surrounding the blocks are involved in the movements of the bedrock resulting mainly from land uplift. From the interpretation of satellite photos, attention has switched over to the interpretation of large-scale maps and stereoscopic aerial photographs. The investigation areas selected by the interpretation of aerial photos have also been studied tentatively on the ground to obtain a more accurate comparative estimation of the different localities. Of the areas chosen for study, the majority consist of granites, which best meet the geological site selection recommendations. The investigation areas have been classified into four categories according to how well they are suited to further study. One important criterion in the classification has been the amount of information obtainable from the bedrock. The areas included in the first category have well exposed and solid bedrock. The areas chosen for inclusion in the second category contain fewer outcrops and are not so easy to study with respect to the structure of the bedrock. The areas included in the third category are generally blanketed under surficial deposits with the result that obtaining reliable information about the bedrock calls for further investigation. The fourth category represents areas where features

    High strain accumulation across the fold-and-thrust belt in Southwestern Taiwan are revealed by the Continuous GPS (cGPS) and SAR interferometry. This high strain is generally accommodated by the major active structures in fold-and-thrust belt of western Foothills in SW Taiwan connected to the accretionary wedge in the incipient are-continent collision zone. The active structures across the high strain accumulation include the deformation front around the Tainan Tableland, the Hochiali, Hsiaokangshan, Fangshan and Chishan faults. Among these active structures, the deformation pattern revealed from cGPS and SAR interferometry suggest that the Fangshan transfer fault may be a left-lateral fault zone with thrust component accommodating the westward differential motion of thrust sheets on both side of the fault. In addition, the Chishan fault connected to the splay fault bordering the lower-slope and upper-slope of the accretionary wedge which could be the major seismogenic fault and an out-of-sequence thrust fault in SW Taiwan. The big earthquakes resulted from the reactivation of out-of-sequence thrusts have been observed along the Nankai accretionary wedge, thus the assessment of the major seismogenic structures by strain accumulation between the frontal décollement and out-of-sequence thrusts is a crucial topic. According to the background seismicity, the low seismicity and mid-crust to mantle events are observed inland and the lower- and upper- slope domain offshore SW Taiwan, which rheologically implies the upper crust of the accretionary wedge is more or less aseimic. This result may suggest that the excess fluid pressure from the accretionary wedge not only has significantly weakened the prism materials as well as major fault zone, but also makes the accretionary wedge landward extension, which is why the low seismicity is observed in SW Taiwan area. Key words: Continuous GPS, SAR interferometry, strain rate, out-of-sequence thrust.
