    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

    The Cenozoic basanites from Pilchowice (SW Poland) form volcanic plug located exactly at Intra- Sudetic Fault. These basanites belong to the Polish part of the Central European Volcanic Province and contain numerous, usually small (pfu and mg# from 0.915- 0.920 . One xenolith contains clinopyroxene with abundant spongy rims. Primary clinopyroxene is very rare and Al-enriched (mg# 0.92, 0.17 atoms of Al pfu). The spinel is Cr enriched (cr# 0.46-0.68) and is usually associated with clinopyroxene. Orthopyroxene is depleted in REE compared to primitive mantle. Orthopyroxene from majority of xenoliths are strongly LREE depleted ((La/Lu)N = 0.03-0.21). All studied peridotites contain clinopyroxene which is enriched (2 to 70 times) in REE compared to primitive mantle. Clinopyroxene patterns show relative low HREE concentration ((La/Lu)N = 4.75- 19.99), moreover patterns from three samples are convex- upward shaped with inflection point on Nd ((La/Nd)N = 0.36-0.96). Clinopyroxene- poor lithology, high cr# in spinel and LREE- depleted nature of orthopyroxene suggest that upper mantle sampled by Pilchowice basanite is a restite after partial melting. The LREE enriched composition of clinopyroxene suggest that peridotites were metasomatised. Clinopyroxene convex- upward shaped REE plots with inflection point on Nd is typical for metasomatism related with alkaline melt. On the other hand very low ratios of Ti/ Eu (24.8- 738.9) and high (La/ Yb)N (3.5- 17) ratio (Coltorti, 1999) suggest that the metasomatic agent was either a mixture of alkaline silicate melt with carbonatite or peridotite reaction with two independent agents is recorded.

    Field observations and preliminary geochemical data are presented for large (>500x1000m) peridotite enclaves from the Fiskefjord region of SW Greenland. These ultramafic complexes are dominated by dunite, amphibole-harzburgite, lesser amounts of norite and horizons of stratiform chromitite and are therefore interpreted as cumulate rocks[1]. The ultramafic enclaves are hosted by intrusive tonalitic orthogneiss, which provide U-Pb zircon minimum age constraints of ca. 2980 Ma, whereas preliminary Re-Os isotope data on the dunite and chromitite yield TRD ages of ca. 3300 Ma[2]. Dunite has highly forsteritic olivine compositions with Mg# mostly around 92 to 93, which is uncorrelated with the bulk-rock mg# or modal chromite contents. This indicates that the primary olivine records equilibration with a highly magnesian parental magma, which may have been responsible for the strong depletion of the SCLM in this region. Amphibole and phlogopite is mostly associated with granitoid sheets or infiltrating veins in the dunite and appear to replace chromite. Argon dating (40Ar/39Ar) of the phlogopite yields ages ranging from ca. 3400 Ma to ca. 1750 Ma, with most ages clustering around 3000 Ma. This is consistent with formation of the phlogopite and amphibole by metasomatic processes involving reaction between granitoid-derived siliceous fluids and the ultramafic rocks. The older 40Ar/39Ar age plateaus most plausibly represent excess Ar, potentially inherited from the nearby Itsaq Gneiss Complex (3900 to 3600 Ga) based on its proximity. The youngest 40Ar/39Ar age plateaus on the other hand may potentially signify the closure-age for this system, which could have important implications for determining the exhumation history of the North Atlantic craton.

    Ticks constitute important vectors of human and animal pathogens. Besides the Lyme borreliosis and tick-borne encephalitis, other pathogens such as Babesia spp., Rickettsia spp., and Anaplasma phagocytophilum, are of increasing public health interest. In Poland, as in other European countries, Ixodes ricinus, the most prevalent tick species responsible for the majority of tick bites in humans, is the main vector of A. phagocytophilum. The aim of the study was to estimate the infection level of I. ricinus with A. phagocytophilum in selected districts, not previously surveyed for the presence of this agent. Sampling of questing ticks was performed in 12 forested sites, located in four districts (Legnica, Milicz, Lubań, and Oława) in SW Poland. Altogether, 792 ticks (151 females, 101 males, and 540 nymphs) representing I. ricinus were checked for the presence of A. phagocytophilum. The average infection level was 4.3%, with higher rate reported for adult ticks. The highest percentage of infected adults was observed in Milicz (17.4%) and the lowest in Oława (6.8%). The abundance of questing I. ricinus in all examined sites as well as the infection with A. phagocytophilum indicate for the first time the risk for HGA transmission in SW Poland.

    Full Text Available This paper investigates the petrogenesis of the Seqi Ultramafic Complex, which covers a total area of approximately 0.5 km2. The ultramafic rocks are hosted by tonalitic orthogneiss of the ca. 3000 Ma Akia terrane with crosscutting granitoid sheets providing an absolute minimum age of 2978 ± 8 Ma for the Seqi Ultramafic Complex. The Seqi rocks represent a broad range of olivine-dominated plutonic rocks with varying modal amounts of chromite, orthopyroxene and amphibole, i.e. various types of dunite (s.s., peridotite (s.l., as well as chromitite. The Seqi Ultramafic Complex is characterised primarily by refractory dunite, with highly forsteritic olivine with core compositions having Mg# ranging from about 91 to 93. The overall high modal contents, as well as the specific compositions, of chromite rule out that these rocks represent a fragment of Earth's mantle. The occurrence of stratiform chromitite bands in peridotite, thin chromite layers in dunite and poikilitic orthopyroxene in peridotite instead supports the interpretation that the Seqi Ultramafic Complex represents the remnant of a fragmented layered complex or a magma conduit, which was subsequently broken up and entrained during the formation of the regional continental crust.Integrating all of the characteristics of the Seqi Ultramafic Complex points to formation of these highly refractory peridotites from an extremely magnesian (Mg# ∼ 80, near-anhydrous magma, as olivine-dominated cumulates with high modal contents of chromite. It is noted that the Seqi cumulates were derived from a mantle source by extreme degrees of partial melting (>40%. This mantle source could potentially represent the precursor for the sub-continental lithospheric mantle (SCLM in this region, which has previously been shown to be ultra-depleted. The Seqi Ultramafic Complex, as well as similar peridotite bodies in the Fiskefjord region, may thus constitute the earliest cumulates that formed during the

  6. Ams Fabric and Deformation of The Jawornik Granitoids In The Zloty Stok - Skrzynka Deformation Zone (sudetes, SW Poland)- Preliminary Interpretations.

    Jawornik granitoids comprise the NE-SW trending sequences of the 1cm up to 1 km thick granitoid veins surrounded by schists and gneisses of the Zloty Stok - Skrzynka deformation zone in Eastern Sudetes (SW Poland). According to conflicting theories granitoids are of magmatic origin or were formed from blastomylonitic rocks that underwent multiphase deformation. AMS studies were performed for the 53 sites lo- calized within granitoid veins and within the surrounding gneisses. AMS foliations for granitoid veins of various thickness as well as for gneisses dip at moderate to steep an- gles to N-NW. AMS lineations in the surrounding gneisses plunge subhorizontally to NE-SW that reflects the regional NE-SW shearing components. Magnetic lineations for sites within wider veins of granitoids plunge at low angles (mostly from S to W) but with more varying trends between sites. Mezoscopic tectonic foliations are record- able only in 50% of sites. They show good correlation with AMS planar fabric on the site scale. The uniformity of AMS fabric on the site scale and high AMS anisotropy within all sites (P of 1.05-1.30, T of 0.3-0.6 on average) suggest syntectonic gener- ation of granitoids. Further interpretations of the AMS and tectonic fabrics will be performed when microtectonic studies and chemical analyses results are available.

    The Cenozoic basanite from the Ostrzyca Proboszczowicka in Lower Silesia (SW Poland) belongs to numerous lavas occurring in the NE part of the Central European Volcanic Province. Basanite contains clinopyroxene megacrysts up to 3 cm in size. The clinopyroxene has the composition of aluminian-sodian diopside (mg# 0.61-0.70, 0.08-0.12 atoms Na pfu and 0.88-0.93 atoms Ca pfu). Cr is absent. The REE contents are above the primitive mantle reaching up to 18 x PM at Nd. Primitive-mantle normalized REE patterns show enrichment in LREE relative to HREE (LaN/LuN=3.81-5.01). The REE patterns of all the megacrysts show deflection in La-Nd. The trace element patterns are characterized by positive Zr, Hf and in some cases also Ta anomalies, and negative U, La, Sr, Ti and Pb ones. In some samples strong depletion (down to 0.01 x PM) in Rb and Ba is observed.The Ostrzyca megacrysts formed cumulate, which crystallized from magma similar to the host basanite, but more fractionated and enriched in REE, particularly in LREE (Lipa et al., 2014). This happened at mid-crustal depths (10-15 km) and the new pulse of basanitic magma entrained the crystals forming the non-solidified cumulate and brought them to the surface (Lipa et al., 2014). Clinopyroxene megacrysts contain large, transparent, euhedral apatite crystals up to 7 mm. The major element composition indicates the fluor-apatite with F content ranging from 0.87 to 1.93 wt.%. Chlorine content is strongly variable between grains (0.05-1.75 wt.%). Apatite is strongly enriched in LREE relative to HREE (LaN/LuN=60.39-62.23, about 1000 x PM for LREE and about 10 x PM for HREE). The REE patterns are nearly linear, with slight positive Nd and Gd anomalies. The trace element patterns are characterized by very strong negative anomalies of HFSE (Nb, Ta, Zr, Hf, Ti) and Pb, and weaker negative Sr anomaly. Concentration of Yb and Lu is on the level 10 x PM, whereas Rb, Hf and Ti are depleted relative to PM. Apatite preceded clinopyroxene

    River basins located in the Central Sudetes (SW Poland) demonstrate a high vulnerability to flooding. Four mountainous basins and the corresponding outlets have been chosen for modeling the streamflow dynamics using TOPMODEL, a physically based semi-distributed topohydrological model. The model has been calibrated using the Monte Carlo approach—with discharge, rainfall, and evapotranspiration data used to estimate the parameters. The overall performance of the model was judged by interpreting the efficiency measures. TOPMODEL was able to reproduce the main pattern of the hydrograph with acceptable accuracy for two of the investigated catchments. However, it failed to simulate the hydrological response in the remaining two catchments. The best performing data set obtained Nash-Sutcliffe efficiency of 0.78. This data set was chosen to conduct a detailed analysis aiming to estimate the optimal timespan of input data for which TOPMODEL performs best. The best fit was attained for the half-year time span. The model was validated and found to reveal good skills.

    The Purang harzburgite massif in SW Tibet (China) hosts abundant chrome ore deposits. Ores consist of 20 to >95% modal chromian spinel (Cr-spinel) with mylonitic fabric in imbricate shaped pods. The composition of Cr-spinel in these ores ranges from Al-rich [Cr#Sp or Cr/(Cr + Al) × 100 = 47.60-57.56] to Cr-rich (Cr#Sp: 62.55-79.57). Bulk platinum-group element (PGE) contents of chromitites are also highly variable ranging from 17.5 ppb to ∼2.5 ppm. Both metallurgical and refractory chromitites show a general enrichment in the IPGE (Os, Ir and Ru) with respect to the PPGE (Rh, Pt and Pd), resulting mostly in right-sloping primitive mantle (PM)-normalized PGE profiles. The platinum-group mineral (PGM) assemblages of both chromitite types are dominated by heterogeneously distributed, euhedral Os-bearing laurite inclusions in Cr-spinel. The Purang chromitites have quite inhomogeneous 187Os/188Os ratios (0.12289-0.13194) that are within the range of those reported for mantle-hosted chromitites from other peridotite massifs. Geochemical calculations demonstrate that the parental melts of high-Cr chromitites were boninitic, whereas those of high-Al chromitites had an arc-type tholeiitic affinity. Chromite crystallization was most likely stimulated by changes in magma compositions due to melt-peridotite interaction, leading to the establishment of a heterogeneous physicochemical environment during the early crystallization of the PGM. The highly variable PGE contents, inhomogeneous Os-isotopic compositions and varying Cr#Sp ratios of these chromitites imply a polygenetic origin for them from spatially distinct melt inputs. The generally low γOs values (different sections of a heterogeneously depleted mantle source region. These melts were most likely produced in the mantle wedge above a downgoing lithospheric slab.

    The Sanbagawa subduction-type metamorphic belt in SW Japan represents the deepest exposed portion of a Mesozoic accretionary complex along the Japanese island arc. Located on the island of Shikoku, the Higashi-akaishi peridotite body is the largest ultramafic lens within the Sanbagawa belt and is dominantly composed of dunite, lherzolite and garnet clinopyroxenite, interfingered in one locality with quartz-rich eclogite. Previous work indicates the P-T history of the peridotite includes rapid prograde metamorphism with peak temperatures of 700-810°C and pressures of 2.9-3.8 GPa at approximately 110-120 Ma. Here we present major and trace element and isotopic data for samples within the Higashi-akaishi peridotite body that suggest it records subduction zone melting processes. Ultramafic samples range from 40-52 wt. % SiO2 and 21-45 wt. % MgO with olivine and clinopyroxene Mg#s as high as 0.93 and have trace element concentrations diagnostic of subduction zone processes. The quartz-rich eclogite contains 62 wt. % SiO2, 6 wt. % MgO and 13 wt. % Al2O3 and has trace element concentrations that are enriched relative to the ultramafic samples. 87Sr/86Sr (.703237-.704288), 143Nd/144Nd (ɛNd=+2-6) and Pb isotopic compositions are within the range of Japanese arc rocks. 187Os/188Os values range from typical mantle values (0.123-0.129), to slightly elevated (0.133) in one peridotite with an unusually low Os content, to a high of 0.145 in the quartz-rich eclogite. The presence of garnet porphyroblasts that enclose primary euhedral chlorite, together with the chemical evidence, suggest these samples are associated with mantle melting in the presence of H2O near their peak P-T conditions and may represent both residues and trapped melts within a paleo-mantle wedge. The peak P-T conditions of these rocks are also similar to the solidus conditions of H2O-saturated fertile mantle based on experimental determinations. Thus the Higashi-akaishi peridotite may be a real world analog

    Although Alpine peridotites are relatively common in collisional orogenic zones, garnet-bearing peridotites are rare and only associated with high pressure/ultra-high pressure or temperature (HP/UHP or T) terranes [Brueckner and Medaris, 2000; Medaris, 1999]. Until recently all reported occurrences of Alpine-type garnet peridotites and HP/UHP terranes were in Eurasia and Africa, with one occurrence in the Seward Peninsula, Alaska [Till, 1981;Lieberman and Till, 1987]. Now a new Alpine-type garnet peridotite locality has been discovered in the Caribbean island of Hispaniola. This discovery is the second of its kind in the Americas.

    High-temperature peridotites by definition yield equilibration temperatures greater than 1100 degrees C. On the basis of temperature and pressure calculations, these high-temperature peridotites are amongst the deepest samples entrained by kimberlites on route to the surface. Conflicting models proposing either a lithospheric or asthenospheric origin for the high-temperature peridotites have been suggested. A detailed study of these xenoliths from a single locality, the Jagersfontein kimberlite in the Orange Free State, has been completed as a means of resolving this controversy. 10 refs., 2 figs

    The extensive uranium exploration and mining activities were carried out in the Lower Silesia (SW Poland) in the early 1950's, under direction of Soviet Union experts. Prospecting for uranium in Poland was initiated in 1947 when a bilateral agreement between the Polish and USSR governments was concluded. According to that agreement all uranium produced in Poland was transported to the Soviet Union. A systematic exploration programme, including geological, geophysical and geochemical surveys and related research, was carried out until 1966. The extensive uranium exploration was undertaken in number of localities in the Lower Silesia

    Ultramafic rocks exposed on the continent serve as a window into oceanic and continental processes of water-peridotite interaction, so called serpentinization. In both environments there are active carbon and sulfur cycles that contain abiogenic and biogenic processes, which are eventually imprinted in the geochemical signatures of the basement rocks and the calcite and magnesite deposits associated with fluids that issue from these systems. Here, we present the carbon and sulfur geochemistry of ultramafic rocks and carbonate deposits from the Santa Elena ophiolite in Costa Rica. The aim of this study is to leverage the geochemistry of the ultramafic sequence and associated deposits to distinguish between processes that were dominant during ocean floor alteration and those dominant during low-temperature, continental water-peridotite interaction. The peridotites are variably serpentinized with total sulfur concentrations up to 877 ppm that is typically dominated by sulfide over sulfate. With the exception of one sample the ultramafic rocks are characterized by positive δ34Ssulfide (up to + 23.1‰) and δ34Ssulfate values (up to + 35.0‰). Carbon contents in the peridotites are low and are isotopically distinct from typical oceanic serpentinites. In particular, δ13C of the inorganic carbon suggests that the carbon is not derived from seawater, but rather the product of the interaction of meteoric water with the ultramafic rocks. In contrast, the sulfur isotope data from sulfide minerals in the peridotites preserve evidence for interaction with a hydrothermal fluid. Specifically, they indicate closed system abiogenic sulfate reduction suggesting that oceanic serpentinization occurred with limited input of seawater. Overall, the geochemical signatures preserve evidence for both oceanic and continental water-rock interaction with the majority of carbon (and possibly sulfate) being incorporated during continental water-rock interaction. Furthermore, there is

    Wołek Hill is one of the best examined exposures of Cenozoic volcanic rocks from SW Poland (Nowak, 2012). This is related with two facts: a great amount of mantle xenoliths were collected from that outcrop and this is one of two occurrences in Poland were modal metasomatism (related with amphibole crystals presence) was recognized. Wołek Hill is a relatively small exposure and belongs to the Złotoryja Volcanic Field, which is one of the volcanic concentrations in the Polish part of the Central European Volcanic Province (Ladenberger et al. 2006). Based on previous observations olivine crystals from the inside part of xenoliths occasionally display internal inhomogeneity visible on a BSE image. Such inhomogeneity has been related to olivine "sub-grains" with slightly shifted crystal axis. Those "sub-grains" are visible in optical microscope as transitional lamellae (Nowak, Stawikowski 2009). Besides the mentioned visible inhomogeneity olivine crystals also show diversity in Ca content inside single crystals (sometimes even more than 200 ppm). EPMA standard measurements (15 kV, 20 nA, time: 40 seconds) were limited to beam size and detection limits of the microprobe (most of the obtained results oscillate close to the detection limits - or even below it). Special conditions EPMA analyses (15 kV, 100nA, time: 100s) confirmed the differences in Ca content in the studied olivines, but did not provide any idea on how to interpret the results (Nowak, 2012). In this short summary we present preliminary data of olivine minor element composition (Ca, Zn, Cr, Ti, Co, K and also Mn, Ni, Fe) obtained with Particle Induced X-ray Emission(PIXE) measurements performed at the HZDR in Dresden using a 3 MeV proton beam, 1-1.5 nA current and an acquisition time of 3 hrs for each scan. The size of individual scans varied from ca. 30 μm up to 60-65 μm, with 8 x 8 measurement points - min. 4 μm in diameter. The measurements have been analysed with the GeoPIXE software (Ryan, 2001

    "Tectonically emplaced" mantle rocks include subcontinental, suboceanic, and subarc mantle rocks that were tectonically exhumed from the upper mantle and occur:(i) as dispersed ultramafic bodies, a few meters to kilometers in size, in suture zones and mountain belts (i.e., the "alpine," or "orogenic" peridotite massifs - De Roever (1957), Thayer (1960), Den Tex (1969));(ii) as the lower ultramafic section of large (tens of kilometers) ophiolite or island arc complexes, obducted on continental margins (e.g., the Oman Ophiolite and the Kohistan Arc Complex - Coleman (1971), Boudier and Coleman (1981), Burg et al. (1998));(iii) exhumed above the sea level in ocean basins (e.g., Zabargad Island in the Red Sea, St. Paul's islets in the Atlantic and Macquarie Island in the southwestern Pacific - Tilley (1947), Melson et al. (1967), Varne and Rubenach (1972), Bonatti et al. (1981)).The "abyssal peridotites" are samples from the oceanic mantle that were dredged on the ocean floor, or recovered from drill cores (e.g., Bonatti et al., 1974; Prinz et al., 1976; Hamlyn and Bonatti, 1980).Altogether, tectonically emplaced and abyssal mantle rocks provide insights into upper mantle compositions and processes that are complementary to the information conveyed by mantle xenoliths (See Chapter 2.05). They provide coverage to vast regions of the Earth's upper mantle that are sparsely sampled by mantle xenoliths, particularly in the ocean basins and beneath passive continental margins, back-arc basins, and oceanic island arcs.Compared with mantle xenoliths, a disadvantage of some tectonically emplaced mantle rocks for representing mantle compositions is that their original geodynamic setting is not exactly known and their significance is sometimes a subject of speculation. For instance, the provenance of orogenic lherzolite massifs (subcontinental lithosphere versus upwelling asthenosphere) is still debated (Menzies and Dupuy, 1991, and references herein), as is the original setting

    In this investigation we focus on the evaluation of changes in metal pollution between 1986 until 2011 by Sphagnum species as bioindicators in 100 km part of the Sudety mountains influenced by the former Black Triangle Region. Concentrations of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn were measured in various Sphagnum species all from ombrotrophic bogs in the Sudety mountains (SW Poland). The tested hypothesis was that overall improvements in pollution control in the former Black Triangle Region between 1986 until recent reduced the amount of metals deposited and accumulated by these plants. Concentrations of Cd, Cr, Cu, Fe, Pb and Zn in Sphagnum species were very high in 1986 indicating a heavy pollution of the examined bogs in this period, and significantly higher than in samples collected in 2011. The PCCA ordination showed the similar pattern in all bogs. In 2011 concentration of the Co was significantly higher in hollow species and concentration of Mn was significantly higher in those from hummocks. Differences between hollow/hummock sites were more important than species-specific abilities of Sphagnum mosses to accumulate metals. Species from hollows were better bioindicators of Co and those from hummocks were better bioindicators of Mn pollution. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Concentrations of the elements Cd, Cr, Cu, Fe, Li, Mn, N, Ni, Pb and Zn in Andromeda polifolia, Oxycoccus microcarpus and in the peat in which these plants grew were measured in the Western Sudety (Karkonosze and Izerskie Mts., SW Poland). Of both the investigated plant fruit, O. microcarpus harvested from wild populations are commonly used as medicines. Samples from ombrotrophic bogs were investigated within the area influenced by exhausts of the former Black Triangle, one of the most heavily industrialized and polluted areas in Europe. A. polifolia and O. microcarpus growing at the highest elevations contained the highest Cu, Li, Ni, Mn and Zn concentrations and in addition O. microcarpus also contained the highest Cr concentrations. Both the investigated species have wide circumpolar distribution in ombrotrophic mires of the Northern hemisphere. As this type of mires is nourished solely by atmospheric deposition, the increased metal concentrations in A. polifolia and O. microcarpus may be an indication that their habitats receive an atmospheric input of long-range transported pollution. Our investigation proves that both species are able to accumulate elevated metal levels and may be used in the bioindication of the metal status in ombrotrophic mires. Controlling the collection of O. microcarpus fruit for consumption and medicinal purposes is recommended as this species can accumulate increased metal levels. However, further more detailed studies are necessary to verify the inner translocation of metals into fruit.

    Serpentinized mantle peridotites are widely supposed to be significant sources of the magnetic, gravity and seismic anomalies in mid-oceanic ridges, forearcs and suture zones. However, the relationship between the magnetic properties of variably serpentinized peridotites and the serpentinization process is still under debate. Ophiolite outcrops commonly comprise peridotites in different stages of serpentinization and these ophiolitic peridotites are ideal to investigate the magnetic signatures of suture zones. The Zedong ophiolite locates in the eastern part of the Yarlung-Zangbo suture zone, SE Tibet (China), and the peridotite massif represents the remnants of the Neo-Tethyan lithospheric mantle. The harzburgite and lherzolite samples show densities between 3.316 and 2.593 g cm-3, and vary from the freshest to >90% serpentinized peridotites. The magnetic susceptibility curves from room temperature to 700ºC mainly show the Curie temperatures of 585ºC for pure magnetite. The low-temperature (20-300 K) demagnetization curves show the Verwey transitions at 115-125 K, suggesting that magnetite is also the dominant remanence-carrying phase. The hysteresis data of the peridotites fall in the region of pseudo-single-domain (PSD) and follow the theoretical trends for mixtures of single domain (SD) and multidomain (MD) magnetite. The first-order reversal curve (FORC) diagrams suggest that the magnetite is dominantly interacting SD + PSD particles for S 40% serpentinized samples. The susceptibility and saturation magnetization of the Zedong peridotites range from 0.9 to 30.8 × 10‒3 (SI) and 14.1 to 1318 × 10‒3 Am2 kg‒1, respectively, and both show consistent trends with increasing degrees of serpentinization. The S serpentinization of ophiolitic peridotites, whereas the S > 40% peridotites have higher susceptibilities of 0.02-0.03 (SI) and fall in the region of abyssal peridotites. Our results suggest that the Zedong ophiolitic peridotites probably experienced a

    2014-12-01

    Located in the Sanbagawa subduction-related high-pressure metamorphic belt in SW Japan on the island of Shikoku, the Higashi-akaishi peridotite body is composed of dunite, lherzolite and garnet clinopyroxenite, interfingered in one locality with quartz-rich eclogite. Previous work indicates the P-T history of the peridotite includes rapid prograde metamorphism with peak temperatures of 700-810°C and pressures of 2.9-3.8 GPa [1] at ~88-89 Ma followed by rapid exhumation at >2.5 cm/yr [2,3]. Major and trace element and isotopic data from samples within the Higashi-akaishi peridotite presented here and in another recent study [4] provide a record of subduction zone melting processes in a paleo-mantle wedge. Ultramafic samples range from 40-52 wt.% SiO2, 1-11 wt.% Al2O3 and 21-45 wt.% MgO with olivine and clinopyroxene Mg#'s as high as 0.93. The quartz-rich eclogite contains 62 wt.% SiO2, 6 wt.% MgO and 13 wt.% Al2O3 with trace element concentrations that are enriched relative to the ultramafic samples. 87Sr/86Sr (.703237-.704288), 143Nd/144Nd (ɛNd=+2 to +6) and Pb isotopic compositions are within the range of previously studied Japanese arc rocks. We interpret the pyroxenites as shallowly crystallized cumulates with varying amounts of trapped hydrous melt and the harzburgites as residues of melting. The peak P-T conditions of these rocks are similar to the solidus conditions of H2O-saturated fertile mantle near the base of the mantle wedge [5,6]. The presence of garnet porphyroblasts that enclose primary euhedral chlorite together with the chemical evidence, suggest these samples are associated with mantle melting in the presence of H2O. Major element modeling suggests the quartz-rich eclogite composition can be reproduced through mixing melts of subducted sediment with wet peridotite melts in the mantle wedge. Thus the Higashi-aikashi rock suite provides an in-situ record of the beginnings of hydrous melting and the mechanisms of metasomatism in the mantle wedge

  11. Deeply concealed half-graben at the SW margin of the East European Craton (SE Poland — Evidence for Neoproterozoic rifting prior to the break-up of Rodinia

    2018-01-01

    Full Text Available Baltica was one of continents formed as a result of Rodinia break-up 850–550 Ma. It was separated from Amazonia(? by the Tornquist Ocean, the opening of which was preceded by Neoproterozoic extension in a network of continental rifts. Some of these rifts were subsequently aborted whereas the Tornquist Rift gave rise to splitting of Rodinia and formation of the Tornquist Ocean. The results of 1-D subsidence analysis at the fossil passive margin of Baltica provided insight in the timing and kinematics of continental rifting that led to break-up of Rodinia. Rifting was associated with Neoproterozoic syn-rift subsidence accompanied by deposition of continental coarse-grained sediments and emplacement of continental basalts. Transition from a syn-rift to post-rift phase in the latest Ediacaran to earliest early Cambrian was concomitant with deposition of continental conglomerates and arkoses, laterally passing into mudstones. An extensional scenario of the break-up of Rodinia along the Tornquist Rift is based on the character of tectonic subsidence curves, evolution of syn-rift and post-rift depocenters in time, as well as geochemistry and geochronology of the syn-rift volcanics. It is additionally reinforced by the high-quality deep seismic reflection data from SE Poland, located above the SW edge of the East European Craton. The seismic data allowed for identification of a deeply buried (11–18 km, well-preserved extensional half-graben, developed in the Palaeoproterozoic crystalline basement and filled with a Neoproterozoic syn-rift volcano-sedimentary succession. The results of depth-to-basement study based on integration of seismic and gravity data show the distribution of local NE–SW elongated Neoproterozoic depocenters within the SW slope of the East European Craton. Furthermore, they document the rapid south-eastwards thickness increase of the Neoproterozoic succession towards the NW–SE oriented craton margin. This provides evidence

  12. Extreme Hf-Os Isotope Compositions in Hawaiian Peridotite Xenoliths: Evidence for an Ancient Recycled Lithosphere

    2004-12-01

    We report on the first combined Hf-Os isotope systematics of spinel peridotite xenoliths from the Salt Lake Crater (SLC), Pali and Kaau (PK) vents from the island of Oahu, Hawaii. These peridotites are thought to represent the Pacific oceanic lithosphere beneath Oahu, as residues of MORB-type melting at a paleo-ridge some 80-100Ma ago. Clinopyroxene mineral separates in these peridotites have very similar Nd and Sr isotope compositions with the post erosional Honolulu Volcanics (HV) lavas that bring these xenoliths to the surface. This and their relatively elevated Na and LREE contents suggest that these peridotites are not simple residues of MORB-type melting but have experience some metasomatic enrichment by the host HV lavas. However, the SLC and PK xenoliths show an extreme range in Hf isotope compositions towards highly radiogenic values (ɛ Hf= 7-80), at nearly constant Nd isotope compositions (ɛ Nd= 7-10), unlike any OIB or MORB basalt. Furthermore, these Oahu peridotites show a bimodal distribution in their bulk rock 187Os/186Os ratios: the PK peridotites have similar ratios to the abyssal peridotites (0.130-0.1238), while the SLC peridotites have highly subchondritic ratios (0.1237-0.1134) that yield 500Ma to 2Ga Re-depletion ages. Hf-Os isotopes show a broad negative correlation whereby the samples with the most radiogenic 176Hf/177Hf have the most unradiogenic 187Os/186Os ratios. Based on their combined Hf-Os-Nd isotope and major element compositions, the PK peridotites can be interpreted as fragments of the Hawaiian lithosphere, residue of MORB melting 80-100Ma ago, that have been variably metasomatized by the host HV lavas. In contrast, the extreme Hf-Os isotope compositions of the SLC peridotites suggest that they cannot be the source nor residue of any kind of Hawaiian lavas, and that Hf and Os isotopes survived the metasomatism or melt-rock reaction that has overprinted the Nd and Sr isotope compositions of these peridotites.

    Introduction Study of the petrology of the ophiolites as the relics of ancient oceanic lithosphere, is a powerful tool to reconstruct Earth’s history. Mantle peridotites have mostly undergone alteration and serpentinization to some extent. Thus, the relics of metamorphic signatures from the upper mantle and crustal processes from most of the peridotites have been ruined. Several recent papers deal with the mantle peridotites of Nain Ophiolite (e.g. Ghazi et al., 2010). However, no scientif...

    The 87Sr/86Sr ratios in some bulk abyssal and alpine peridotites are too high to be binary mixtures of depleted mantle and seawater components. The apparent excess, or "orphan," 87Sr appears to be separated from its radioactive parent. Such observations were widely held to be analytical artifacts. Study of several occurrences of orphan 87Sr shows that the orphan component in abyssal peridotite is located in the alteration products of olivine and enstatite in the peridotite. The orphan 87Sr is most likely introduced by infiltration of low-temperature (<200^circC) seawater bearing suspended detrital particulates. These particulates include grains of detrital clay that are partly derived from continental (that is, granitic) sources and thus are highly radiogenic. Orphan 87Sr and other radiogenic isotopes may provide a tracer for low-temperature seawater penetrating into the oceanic crust.

  16. Tracing alteration of mantle peridotite in the Samail ophiolite using Mg isotopes

    2017-12-01

    Magnesium is one of the main constituents of mantle peridotite ( 22.8 wt%), which has a homogeneous Mg isotopic composition (d26Mg = -0.25 ± 0.04 ‰ (2 sd) DSM3, Teng et al 2010 GCA). Mg isotopes are used as tracers of continental and oceanic weathering as they exhibit variable degrees of fractionation during alteration depending on the lithology. Here we report some of the first Mg isotopic compositions of the mantle section of the Samail ophiolite in Oman and its alteration products. The mantle section of the ophiolite is composed mainly of depleted harzburgites and dunites with mantle-like d26Mg (-0.25, -0.21 ‰). Mantle peridotite is far from equilibrium in near surface conditions leading to rapid, extensive serpentinization, carbonation and oxidation, as well as other geochemical changes. Our analyzed samples encompass most of the alteration of peridotite products observed in Oman including listvenites (completely carbonated peridotite) near the basal thrust of the ophiolite, massive magnesite veins within peridotite outcrops, and heavily altered harzburgites. Magnesite listvenites have d26Mg slightly below mantle values (-0.33, -0.33‰) while dolomite listvenites are significantly lighter (-1.46, -0.89‰). This suggests that heavy Mg isotopes were removed from the listvenites during ophiolite emplacement. Heavily altered peridotite from Wadi Fins exhibit alteration halos with drastic changes in composition. The most oxidized areas are enriched in Fe and depleted in Mg compared to the cores of the samples. These variations in Mg concentrations are complemented by a shift to heavy Mg isotopic compositions (0.74, 0.86‰), among the heaviest d26Mg values that have been reported in altered peridotite. Potential sinks for light isotopes removed from such alteration zones are massive magnesite veins with very light compositions (-3.39, -3.14‰). The fractionation of Mg isotopes observed in the mantle section of the ophiolite spans more than 50% of the known

    Recently acquired seismic reflection data provide better insight in the structural style of extensive sedimentary series overlying the SW slope of the East European Craton (EEC) in Poland. The two main seismic datasets - the POLCRUST-01 profile and PolandSPAN survey - yielded contrasting thick - and thin-skinned structural models for the same structural units in SE Poland. We reattempt an interpretation of the POLCRUST-01 profile using techniques of cross-section balancing and restoration aided by 2D forward seismic modelling. An outcome is the thin-skinned structural model is. This solution relies on a continuous top of the EEC crystalline basement well represented in the seismic data as well as on fragmentary, yet conclusive seismic geometries in shallow depth intervals proving the Ediacaran-Palaeozoic series to be thrust and folded. A Variscan (late Carboniferous) compressional regime is consequently invoked to explain thin-skinned structuring of the pre-Permian sedimentary pile and > 20 km of calculated shortening. We demonstrate an ambiguous nature of the top-basement irregularities previously used as indicators of basement-rooted vertical faulting. The tilt and abrupt increase of the top-basement taper under the thin-skinned belt are attributed to pre-Ordovician tectonic processes operating along the SW margin of the EEC. Post-rift subsidence and/or flexural loading giving rise to a broken foreland plate are invoked.

  18. The Finero phlogopite-peridotite massif: an example of subduction-related metasomatism

    Science.gov (United States)

    Zanetti, Alberto; Mazzucchelli, Maurizio; Rivalenti, Giorgio; Vannucci, Riccardo

    The Finero peridotite massif is a harzburgite that suffered a dramatic metasomatic enrichment resulting in the pervasive presence of amphibole and phlogopite and in the sporadic occurrence of apatite and carbonate (dolomite)-bearing domains. Pyroxenite (websterite) dykes also contain phlogopite and amphibole, but are rare. Peridotite bulk-rock composition retained highly depleted major element characteristics, but was enriched in K, Rb, Ba, Sr, LREE (light rare earth elements) (LaN/YbN=8-17) and depleted in Nb. It has high radiogenic Sr (87Sr/86Sr(270)=0.7055-0.7093), low radiogenic Nd (ɛNd(270)=-1 to -3) and EMII-like Pb isotopes. Two pyroxenite - peridotite sections examined in detail show the virtual absence of major and trace element gradients in the mineral phases. In both rock types, pyroxenes and olivines have the most unfertile major element composition observed in Ivrea peridotites, spinels are the richest in Cr, and amphibole is pargasite. Clinopyroxenes exhibit LREE-enriched patterns (LaN/YbN 16), negative Ti and Zr and generally positive Sr anomaly. Amphibole has similar characteristics, except a weak negative Sr anomaly, but incompatible element concentration 1.9 (Sr) to 7.9 (Ti) times higher than that of coexisting clinopyroxene. Marked geochemical gradients occur toward apatite and carbonate-bearing domains which are randomly distributed in both the sections examined. In these regions, pyroxenes and amphibole (edenite) arelower in mg## and higher in Na2O, and spinels and phlogopite are richer in Cr2O3. Both the mineral assemblage and the incompatible trace element characteristics of the mineral phases recall the typical signatures of ``carbonatite'' metasomatism (HFSE depletion, Sr, LILE and LREE enrichment). Clinopyroxene has higher REE and Sr concentrations than amphibole (amph/cpxDREE,Sr=0.7-0.9) and lower Ti and Zr concentrations. It is proposed that the petrographic and geochemical features observed at Finero are consistent with a subduction

    2005-01-01

    The Trinity peridotite represents a rare opportunity to examine a relatively fertile plagioclase peridotite that was exhumed and later subjected to intrusive events in a seafloor environment, followed by its emplacement and incorporation into a continent. Over 250 stable isotopic determinations on whole rocks and minerals elucidate the hydrothermal evolution of the Trinity complex. All three serpentine polymorphs are present in the Trinity peridotite; these separate on the basis of their ??D values: antigorite, -46 serpentinization, or overprinting of earlier low-temperature seafloor serpentinization. Regionally, contours of ??D values exhibit bull's-eye patterns associated with the gabbroic plutons, with ??D maxima coinciding with the blackwall alteration at the margins on the plutons. In contrast to the hydrogen isotope behavior, oxygen isotope values of the three polymorphs are indistinguishable, spanning the range 5.3 history: (1) lithospheric emplacement and cooling of the peridotite in an oceanic environment ??? 472 Ma; (2) intrusion of gabbroic plutons into cold peridotite in an arc environment between 435 and 404 Ma; and finally (3) intrusion of felsic plutons between 171 and 127 Ma, long after the peridotite was incorporated into the continental crust.

    The Monte Maggiore peridotite body, cropping out within the Alpine Corsica metamorphic belt, is an ophiolite massif derived from the more internal setting of the Jurassic Ligurian Tethys basin. It is mostly composed by spinel and plagioclase peridotites that are cut by MORB gabbroic dykes. The spinel peridotites, similarly to other ophiolitic peridotites from the Internal Ligurides, have been considered, on the basis of their low abundance of fusible components, low Si and high Mg contents, as refractory residua after MORB-type partial melting related to the formation of the Jurassic basin (e.g. Rampone et al., 1997). Recent studies (e.g. Müntener & Piccardo 2003; Rampone et al. 2008) have evidenced that these depleted spinel peridotites show diffuse melt-rock interaction micro-textures and contrasting bulk vs. mineral chemistry features which cannot be simply reconciled with partial melting. Accordingly, these peridotites have been recognized as reactive peridotites, formed by interaction of pristine peridotites with melts percolating by porous flow. Geochemical data have evidenced the depleted MORB signature of the percolating melts. Recent field studies at Monte Maggiore (Piccardo, 2007; Piccardo & Guarnieri, 2009), have revealed: 1) the presence and local abundance of pyroxenite-bearing, cpx-rich spinel lherzolites and 2) the replacement relationships of the reactive peridotites on the pyroxenite-bearing lherzolite rock-types. The pyroxenite-veined spinel lherzolites record a composite history of subsolidus evolution under lithospheric P-T conditions, thus indicating their provenance from the sub-continental lithospheric mantle. Accordingly, the pristine sub-continental mantle protoliths were infiltrated by MORB melts and transformed by melt-rock interaction to reactive spinel peridotites and refertilized by melt impregnation to plagioclase-enriched peridotites.

    The timing of cooling and exhumation of mantle peridotites in oceanic and continental settings has been challenging to determine using traditional geo- and thermochronometric techniques. Hence, the timing of the exhumation of mantle rocks to the Earth's surface at mid-ocean ridges, rifted and passive continental margins, and within continental volcanic and orogenic systems has remained largely elusive or only loosely constrained by relative age bracketing. Magmatic spinel [(Mg, Fe)(Al,Cr)2O4] is a ubiquitous primary mineral phase in mantle peridotites and is often the only primary mineral phase to survive surface weathering and serpentinization. This work explores spinel (U-Th)/He thermochronology as a novel tool to directly date the exhumation and cooling history of spinel-bearing mantle peridotite. Samples were chosen from a range of tectonic and petrologic settings, including a mid-ocean ridge abyssal peridotite (ODP Leg 209), an orogenic tectonic sliver of sub-continental mantle (Lherz massif, France), and a volcanic-rock hosted mantle xenolith (Green Knobs, NM). Spinel grains were selected based on grain size and morphology, screened for internal homogeneity using X-ray computed tomography, and air abraded to eliminate effects of alpha ejection/implantation. These case studies yield spinel He age results that are reproducible and generally in good agreement with independent age constraints. For ODP Leg 209, a spinel He age of 1.1 ± 0.3 Ma (2 SE) (n = 8) is consistent with independent U-Pb and magnetic anomaly ages for the exhumation of oceanic crust by detachment faulting along this segment of the slow-spreading ridge. Spinel from the Lherz massif yield He ages from 60-70 Ma (n = 3), which correspond well with independent thermochronometric constraints for cooling associated with Pyrenean collisional exhumation. Spinel from a mantle xenolith within a previously undated kimberlite diatreme at Green Knobs, New Mexico, generate a reproducible mean He age of 11

    Uptake of CO2 from surface water via mineral carbonation in peridotite can be engineered to achieve negative CO2 emissions. Reaction with peridotite, e.g., CO2 + olivine (A), serpentine (B) and brucite (C), forms inert, non-toxic, solid carbonates such as magnesite. Experimental studies show that A can be 80% complete in a few hours with 30 micron powders and elevated P(CO2) [1,2,3]. B is slower, but in natural systems the rate of B+C is significant [4]. Methods for capture of dilute CO2 via mineral carbonation [4,5,6,7] are not well known, though CO2 storage via mineral carbonation has been discussed for decades [8,9]. Where crushed peridotite is available, as in mine tailings, increased air or water flow could enhance CO2 uptake at a reasonable cost [4,5]. Here we focus on enhancing subsurface CO2 uptake from surface water flowing in fractured peridotite, in systems driven by thermal convection such as geothermal power plants. Return of depleted water to the surface would draw down CO2 from the air [6,7]. CO2 uptake from water, rate limited by flow in input and output wells, could exceed 1000 tons CO2/yr [7]. If well costs minus power sales were 0.1M to 1M and each system lasts 10 years this costs oil industry. Uptake of 1 Gt CO2/yr at 1000 t/well/yr requires 1M wells, comparable to the number of producing oil and gas wells in the USA. Subsurface CO2 uptake could first be applied in coastal, sub-seafloor peridotite with onshore drilling. Sub-seafloor peridotite is extensive off Oman, New Caledonia and Papua New Guinea, with smaller amounts off Spain, Morocco, USA, etc. This would be a regional contribution, used in parallel with other methods elsewhere. To achieve larger scale is conceivable. There is a giant mass of seafloor peridotite along slow-spreading mid-ocean ridges. Could robotic drills enhance CO2 uptake at a reasonable cost, while fabric chimneys transport CO2-depleted water to the sea surface? Does anyone know James Cameron's phone number? [1] O

    Trench peridotites provide information about the influence of subduction initiation on the extent of mantle wedge melting. They preserve melting records throughout subduction history, and as a result, likely experience multiple melt extraction events leading to successive depletion of melt/fluid mobile major and trace elements. To track melting histories of trench peridotites, Re-Os and PGEs can be used as reliable tracers to constrain early melt extraction or re-fertilization events. The Izu-Bonin-Mariana arc, being the largest intra-oceanic subduction system, provides an excellent area to study the formation of supra-subduction zone mantle and crust. Residual peridotite (harzburgite and dunite) samples were collected by dredging from the landward slope of the northern Mariana Trench. The samples are serpentinized to various extents (typical of abyssal peridotites), leaving behind relict grains of spinel, enstatite and olivine embedded within a serpentine matrix along with occasional interstitial diopside. Major element analyses of primary minerals reveal a wide range of variations in Cr# of spinels from 0.31-0.85 indicating 16-20% of melt fraction with dunites apparently experiencing the highest amount of partial melting. For Re-Os and PGE geochemistry, samples with high amounts of spinel (>4 vol %) and variable Cr# were chosen. Initial results show that bulk rock 187Os/188Os ratios range from 0.1113 to 0.1272. All of the samples are sub-chondritic, but in some cases, they are more radiogenic than average abyssal peridotites. Os abundances vary from 1-9 ppb. Sub-chondritic values can be attributed to the samples having evolved from a Re-depleted mantle source indicating a previous melt-extraction event. The cpx-harzburgites, having lower Cr# ( 0.4) are more radiogenic than ultra depleted dunites (Cr# 0.8), which might indicate preferential removal of Os during an apparent higher degree of partial melting experienced by dunites. The higher 187Os/188Os ratios of

    Exhumation of subcontinental mantle peridotite in the Western Mediterranean has been attributed to different tectonic processes including pure extension, transpression, or alternating contractive and extensional processes related with continental subduction followed by extension, before final their contractive intracrustal emplacement. Any model trying to explain the exhumation and emplacement of subcontinental lithospheric mantle peridotites in the westernmost Mediterranean should take into account the available geochronological constraints, as well as the petrological and geochemical processes that lead to internal tectono-magmatic zoning so characteristic of the Betic and Rif orogenic peridotites. Different studies have suggested a Hercynian, Cenozoic-Mesozoic or an Alpine age for the late tectono-magmatic evolution and intra-crustal emplacement of Betic-Rif peridotites. The pervasive presence of Mesozoic U-Pb zircon ages in Ronda UHP and HP garnet pyroxenites does not support a Hercynian age for the intracrustal emplacement of the peridotite. A hyper-extended margin setting for is in good agreement with the Jurassic extensional event that pervasively affected ALKAPECA terrains (i.e. the Alboran, Kabylides, Peloritani, and Calabria domains) in the western Mediterranean due to the opening of the Piemonte-Ligurian Ocean. However, a Jurassic age and a passive margin tectonic setting do not account, among other observations, for the late Miocene thermochronological ages recorded in zircons rims (U-Pb) and garnets (Lu-Hf) in garnet pyroxenites from the Betic-Rif peridotites, the pervasive Miocene resetting of U-Pb zircon and monazite ages in the overlying Jubrique crustal section, the supra-subduction radiogenic signature of late pyroxenite intrusive dikes in the Ronda peridotite, and the arc tholeiitic affinity of late mantle-derived, gabbroic dykes intruding in the Ronda and Ojen plagioclase lherzolites. These data are more consistent with a supra

    Serpentinites, which contain up to 13 wt.% of water, are an important reservoir for chemical recycling in subduction zones. During the last two decades, many observations documented the occurrence of fore-arc mantle serpentinites in different locations. Here, we present petrology and whole rock chemistry for serpentinized peridotites dredged from the Hahajima Seamount, which is located 20-60 km west of the junction of the Bonin Trench and the Mariana Trench. Combined with published geochemical data of serpentinites from the Torishima Seamount, Conical Seamount and South Chamorro Seamount in the Izu-Bonin-Mariana fore-arc region, it will allow us to better understand the average composition of serpentinized fore-arc mantle overlying the subducting slab and the role of serpentinized mantle playing in the subduction zone geochemical cycle. The studied ultramafic rocks from the Hahajima Seamount are extensively serpentinized and hydrated (73 to 83%), with loss of ignition values ranging between 13 and 15 wt.%. Our results show that the serpentinized peridotites have Mg number from 88 to 90, and the average MgO/SiO2 is 0.93. The average Al2O3 (0.48 wt.%) and CaO (0.23 wt.%) contents are very low, consistent with low clinopyroxene abundances, and the overall depleted character of the mantle harzburgite protoliths. The serpentinized peridotites from the Hahajima Seamount exhibit similar "U" shape rare earth element (REE) patterns ([La/Sm]N = 3.1-3.6), at higher overall abundances, to the Conical and South Chamorro Seamount suites. One exceptional sample shows the similar REE pattern as serpentinized peridotites from the Torishima Seamount, with depleted light REE concentration ([La/Sm]N =0.7). All the serpentinized peridotites from these four fore-arc seamounts show strong enrichment in fluid-mobile and lithophile elements (U, Pb, Sr and Li). The geochemical signature of the serpentinized peridotites from the seamounts in the Izu-Bonin-Mariana fore-arc region could be

    Full Text Available Niemodlin countryside (c. 300 km2 is situated in the south-western part of Opole Silesia, SW Poland. Forests occupy c. 40%, arable grounds – 1/3, and meadows and pastures – 7%. There are 31 fish-ponds with a total diked surface of 663 ha. The paper presents results of field investigations carried out during the years 2002-2007 and an analysis of changes in the breeding avifauna over the last 56 years. During the years 2002-2007, 123 breeding and 11 probably breeding bird species were recorded in this area. During the years 1962-2007 151 species were recorded as breeding residents; and additional five species – as probably breeding resident. The following species were recorded as breeding for the first time in 1962-2007: Haliaeetus albicilla, Larus canus, Motacilla cinerea, Saxicola torquata, Locustella luscinioides, Ficedula albicollis, Corvus corax and Carpodacus erythrinus. In the same period the following species became extinct: Podiceps nigricollis, Anas clypeata, Milvus milvus, and Tringa glareola. The following species increaed in numbers in 1962-2007: Coturnix coturnix, Grus grus, Columba oenas, Apus apus, Dryocopus martius, Dendrocopos medius, Motacilla cinerea, Saxicola torquata and Corvus corax. In the same period, Tachybaptus ruficollis, Podiceps cristatus, Podiceps grisegena, Ciconia ciconia, Aythya nyroca, Perdix perdix, Gallinago gallinago, Larus ridibundus, Tyto alba, Alcedo atthis, Picus viridis, Riparia riparia and Corvus cornix decreased in numbers. The areas with the highest concentration of rare and endangered species are postulated to be protected as nature reserves, landscape parks and other spatial forms of nature conservation.

    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.

  10. Experimental Melting Study of Basalt-Peridotite Hybrid Source: Constrains on Chemistry of Recycled Component

    It is believed that magma genesis of OIB is largely influenced by recycled oceanic crust component involved in the mantle plume (e.g., Hauri et al., 1996; Takahashi & Nakajima., 2002; Sobolev et al., 2007). Mallik & Dasgupta (2012) reported that the wall-rock reaction in MORB-eclogite and peridotite layered experiments produced a spectrum of tholeiitic to alkalic melts. However, the proper eclogite source composition is still under dispute. In order to figure out the geochemistry of recycled component as well as their melting process, we conducted a series of high-P, high-T experiments. Melting experiments (1~10hrs) were performed under 2.9GPa with Boyd-England type piston-cylinder (1460~1540°C for dry experiments, 1400~1500°C for hydrous experiments) and 5GPa with Kawai-type multi-anvil (1550~1650°C for dry experiments, 1350~1550°C for hydrous experiments), at the Magma Factory, Tokyo Tech. Spinel lherzolite KLB-1 (Takahashi 1986) was employed as peridotite component. Two basalts were used as recycled component: Fe-enriched Columbia River basalt (CRB72-180, Takahashi et al., 1998) and N-type MORB (NAM-7, Yasuda et al., 1994). In dry experiments below peridotite dry solidus, melt compositions ranged from basaltic andesite to tholeiite. Opx reaction band generated between basalt and peridotite layer hindered chemical reaction. On the other hand, alkali basalt was formed in hydrous run products because H2O promoted melting process in both layers. Compared with melts formed by N-MORB-peridotite runs, those layered experiments with CRB are enriched in FeO, TiO2, K2O and light REE at given MgO. In other words, melts produced by CRB-peridotite layered experiments are close to alkali basalts in OIB and tholeiite in Hawaii, while those by layered experiments with N-MORB are poor in above elements. Thus we propose that Fe-rich Archean or Proterozoic tholeiite (BVSP 1980) would be a possible candidate for recycled component in OIB source.

    Abyssal spinel peridotites from Hess Deep, East Pacific Rise (ODP Leg 147) were investigated concerning their major, minor, and trace element mineral chemistry and the incorporation of structural water in orthopyroxene. The rocks are partially serpentinized harzburgites containing primary minerals of olivine, orthopyroxene, clinopyroxene, and spinel. Orthopyroxene is enstatitic with Mg# (Mg/(Mg + Fe)) between 0.90 and 0.92 and Al2O3 from 0.5 to 2.9 wt.%. The residual harzburgite experienced high degrees of melt removal in the spinel peridotite stability field. The average degree of partial melting was calculated to be 17.5% (range: 16.4-17.8%). Trace element data of ortho- and clinopyroxenes reflect this strong depletion, characteristic for the restitic nature of abyssal peridotites. Mantle re-equilibration temperatures around 1000 °C indicate that, after melt extraction and before exhumation to the ocean floor, the rocks experienced significant cooling in the spinel peridotite facies. Water contents of orthopyroxene range from 86 to 233 wt. ppm H2O with an average concentration of 142 wt. ppm H2O. These results represent the first data on water contents in the sub-pacific mantle obtained by direct measurements of sub-oceanic peridotite. The water contents are not related to mineral chemistry, stratigraphy, melting degree, mantle equilibrium conditions or oxidation state. Calculated post-melt peridotite water contents vary between 40 and 100 wt. ppm H2O. Compared to Mid-Atlantic Ridge peridotites, the East Pacific Rise samples of Leg 147 contain somewhat lower water concentrations than samples from Leg 153 and considerably higher contents than those of Leg 209 (Gose et al., 2009; Schmädicke et al., 2011). In Leg 147, the strongest OH absorbtion band occurs at 3420 cm- 1, wheras orthopyroxene from MAR peridotite (Legs 153 and 209) has its strongest absorbtion band at 3566 and 3522 cm- 1. The mantle equilibrium temperature of Leg 147 peridotites is lower than that

    The age of the emplacement of the Ronda Peridotites has been widely debated during recent decades, and ages ranging from the Palaeozoic to the early Miocene have been proposed, although most of the current interpretations suggest an Oligocene-Miocene age. In this article, we describe two meta-sedimentary formations (the lower one formed by detrital sediments and the upper one by marbles) that were unconformably deposited over the Ronda peridotites and now record low-grade metamorphism. The detrital formation contains layers of acidic rocks with an age of 269±9 Ma and the overlying marbles are assumed to be Triassic. The existence of these unconformable formations over the peridotites is crucial for the dating of the exhumation of the latter. The presence of peridotite clasts in the detrital formation indicates that peridotites were exposed during the Permian and other data suggest that peridotites were exhumed during the late Carboniferous. During the Alpine cycle, the peridotites operated as an element situated at the bottom of the tectonically higher Alpujarride/Sebtide unit (the Jubrique unit) and forming part of it, then being incorporated to the Alpine thrusts of this unit.

    2017-04-01

    Fluid consuming rock transformation processes occur in a variety of settings in the Earth's crust. One such process is serpentinization, which involves hydration of ultramafic rock to form serpentine. With peridotite being one of the dominating rocks in the oceanic crust, this process changes physical and chemical properties of the crust at a large scale, increases the amount of water that enters subduction zones, and might even affect plate tectonics te{jamtveit}. A significant number of papers have studied serpentinization in different settings, from reaction fronts progressing over hundreds of meters te{rudge} to the interface scale fracture initiation te{pluemper}. However, the process represents a complicated multi-physics problem which couples external stress, mechanical deformation, volume change, fracture formation, fluid transport, the chemical reaction, heat production and heat flow. Even though it has been argued that fracture formation caused by the volume expansion allows fluid infiltration into the peridotite te{rudge}, it remains unclear how sufficient water can enter the initially low permeability peridotite to pervasively serpentinize the rock at kilometre scale. In this work, we study serpentinization numerically utilizing a thermo-hydro-mechanical model extended with a fluid consuming chemical reaction that increases the rock volume, reduces its density and strength, changes the permeability of the rock, and potentially induces fracture formation. The two-way coupled hydromechanical model is based on a discrete element model (DEM) previously used to study a volume expanding process te{ulven_1,ulven_2} combined with a fluid transport model based on poroelasticity te{ulven_sun}, which is here extended to include fluid unsaturated conditions. Finally, a new model for reactive heat production and heat flow is introduced, to make this probably the first ever fully coupled chemo-thermo-hydromechanical model describing serpentinization. With this model

    We present pseudosections of Cr-bearing garnet peridotite that together with new mineral-chemical data allow quantification of the early PT conditions of the original lithospheric mantle assemblage (M1) of the Friningen Garnet Peridotite (FGP) located in the central/middle belt of the Seve Nappe Complex in central Sweden. Results indicate that the early, coarse grained, olivine + orthopyroxene + clinopyroxene + "high Cr" garnet assemblage (M1a) was formed at 1100 ± 100 °C and 5.0 ± 0.5 GPa. These metamorphic conditions were followed by an inferred late Proterozoic exhumation event down to 850-900 °C and 1.5 GPa (M1b). The latter PT estimate is based on the breakdown of high-Cr M1a garnet (Cr# = 0.065) + olivine into an orthopyroxene + clinopyroxene + spinel (Cr# = 0.15-0.25) ± pargasite kelyphite (M1b) and the exsolution of garnet from Al-rich orthopyroxene and clinopyroxene. The M1b kelyphite is overprinted by an early-Caledonian UHPM mineral assemblage (M2; T = 800 °C and P = 3.0 GPa), equivalent to the earlier discovered UHP assemblage within an eclogitic dyke that cross-cuts FGP. In the garnet peridotite M2 is displayed by low-Cr garnet (Cr# = 0.030) growing together with spinel (Cr# = 0.35-0.45), both these minerals form part of the olivine + orthopyroxene + clinopyroxene + garnet + spinel + pargasite M2 assemblage. The formation of plagioclase + diopside symplectites after omphacite and breakdown of kyanite to sapphirine + albite in internal eclogite and the breakdown of M2 olivine + garnet to amphibole + orthopyroxene + spinel assemblages (M3) in garnet peridotite indicate post-UHP isothermal decompression down to 750-800 °C and 0.8-1.0 GPa (= M3). Multiphase solid-and fluid inclusion assemblages composed of Sr-bearing magnesite, dolomite or carbon decorate linear defect structures within M1a-b minerals and/or form subordinate local assemblages together with M2 minerals. The latter are interpreted as evidence for infiltration of early-Caledonian COH

    Full Text Available We studied representative samples from a peridotite body situated NE of Sedlice village within the Central- Carpathian Paleogene sediments in the Central Western Carpathians. The relationship of the peridotite to the surrounding Paleogene sediments is not clear. The fractures of the brecciated peridotite margin are healed with secondary magnesite and calcite. On the basis of the presented bulk-rock and electron microprobe data, the wt. % amounts of mineral phases were calculated. Most of calculated “modal” compositions of this peridotite corresponds to harzburgites composed of olivine (∼70-80 wt. %, orthopyroxene (∼17-24 wt. %, clinopyroxene ( < 5 wt. % and minor spinel ( < 1 wt. %. Harzburgites could originate from lherzolitic protoliths due to a higher degree of partial melting. Rare lherzolites contain porphyroclastic 1-2 mm across orthopyroxene (up to 25 wt. %, clinopyroxene (∼ 5-8 wt. % and minor spinel ( < 0.75 wt. %. On the other hand, rare, olivine-rich dunites with scarce orthopyroxene porphyroclasts are associated with harzburgites. Metamorphic mineral assemblage of low-Al clinopyroxene (3, tremolite, chrysotile, andradite, Cr-spinel to chromite and magnetite, and an increase of fayalite component in part of olivine, indicate low-temperature metamorphic overprint. The Primitive Mantle normalized whole-rock REE patterns suggest a depleted mantle rock-suite. An increase in LREE and a positive Eu anomaly may be consequence of interactive metamorphic fluids during serpentinization. Similar rocks have been reported from the Meliatic Bôrka Nappe overlying the Central Western Carpathians orogenic wedge since the Late Cretaceous, and they could be a potential source of these peridotite blocks in the Paleogene sediments.

    Full Text Available This study complements earlier research on wild bees (Apiformes in the “Góra Gipsowa” steppe reserve and other habitats near the town of Kietrz (SW Poland, close to the Czech border. It also attempts to reassess the opinion of some researchers about the Moravian Gate as a migration route of southern species to Poland. 109 bee species were recorded at the study sites, including 10 red-listed ones; southern species accounted for 16.5% of this number. The hypothetical route of migration of thermophilous bees through the Moravian Gate to Poland was analysed and the species composition of southern species at either side of the Moravian Gate compared. The results of this study indicate that at present the Moravian Gate plays no part in the migration of southern bee species to Poland.

    Hole BT1B sampled 3 layers of carbonated peridotite (listvenite, 0-80, 100-180, 185-197 m) separated by 2 layers of carbonate-bearing serpentinite (80-100, 180-185 m), underlain by 100 m metasediment and metabasalt. Listvenites (magnesite and/or dolomite + quartz + Fe-oxyhydroxides + chromian spinel ± fuchsite rocks) replacing mantle peridotite at and near the base of the Samail ophiolite (Stanger 85, Wilde ea 02, Nasir ea 07, Falk & Kelemen 15: FK15) reveal processes of carbon transfer into the mantle wedge (Kelemen & Manning 15) and suggest methods for CO2 capture and storage (Kelemen ea 11). Near BT1, 10 to 200 m thick tabular listvenites interlayered with partly serpentinized harzburgite have contacts parallel to the basal thrust. Imprecise Rb/Sr and 40Ar/39Ar ages indicate listvenite formed during obduction (FK15). Listvenite-peridotite contacts are gradational over 1-2 m. The listvenite matrix is microcrystalline quartz + magnesite. Quartz recrystallized from opal as in listvenites worldwide (Akbulut ea 06, Boschi ea 09, Jurkovic ea 12, Aftabi & Zarrinkoub 13, Posukhova ea 13, Ulrich ea 14) consistent with 80-120°C from clumped isotopes and phase equilibria (FK15). Thus listvenite formed - and deformed ductilely - at low T. Ubiquitous carbonate-rich veins locally comprise >10% of core sections; many have antitaxial textures consistent with expansion due to crystallization pressure. Carbonate-rich veins cut serpentinite and listvenite; veins formed a mesh, followed by replacement of mesh cores. Despite variability in and around veins, average Mg/Si, Fe/Si, Al/Si, Fe/Mg, and Cr/Al in listvenite (75 whole rocks, 7712 XRF scanner points) are indistinguishable from average Samail peridotite. CaO (average 5 wt%, range 0-40) and strongly correlated Sr were added to peridotite, most likely from subducting sediment. Rare core with >10 vol% dolomite has higher Fe/Mg than peridotite, but the same Mg/Si. Thus Mg, Si, Al and Cr, plus Fe in most rocks, were largely

    Although water in the mantle is mostly present as trace H dissolved in minerals, it has a large influence on its melting and rheological properties. The water content of the mantle lithosphere beneath continents is better constrained by abundant mantle xenolith data than beneath oceans where it is mainly inferred from MORB glass analysis. Using Fourier transform infrared (FTIR) spectrometry, we determined the water content of olivine (Ol), clinopyroxene (Cpx) and orthopyroxene (Opx) in spinel peridotite xenoliths from Salt Lake Crater, Oahu, Hawaii, which are thought to represent fragments of the Pacific oceanic lithosphere that was refertilized by alkalic Hawaiian melts. Only Ol exhibits H diffusion profiles, evidence of limited H loss during xenolith transport to the surface. Water concentrations (Ol: 9-28 ppm H2O, Cpx: 246-566 ppm H2O, Opx: 116-224 ppm H2O) are within the range of those from continental settings but higher than those from Gakkel ridge abyssal peridotites. The Opx H2O contents are similar to those of abyssal peridotites from Atlantic ridge Leg 153 (170-230 ppm) but higher than those from Leg 209 (10- 14 ppm). The calculated bulk peridotite water contents (94 to 144 ppm H2O) are in agreement with MORB mantle source water estimates and lower than estimates for the source of Hawaiian rejuvenated volcanism (approx 540 ppm H2O) . The water content of Cpx and most Opx correlates negatively with spinel Cr#, and positively with pyroxene Al and HREE contents. This is qualitatively consistent with the partitioning of H into the melt during partial melting, but the water contents are too high for the degree of melting these peridotites experienced. Melts in equilibrium with xenolith minerals have H2O/Ce ratios similar to those of OIB

    The Archean Fiskenæsset Complex, SW Greenland, consists of an association of ca. 550-meter-thick layered anorthosite, leucogabbro, gabbro, and ultramafic rocks (peridotite, pyroxenite, dunite, hornblendite). The complex was intruded by tonalite, trondhjemite, and granodiorite (TTG) sheets (now...... orthogneisses) during thrusting that was followed by several phases of isoclinal folding. The trace element systematics of the Fiskenæsset Complex and associated volcanic rocks are consistent with a supra-subduction zone geodynamic setting. The Fiskenæsset anorthosites, leucogabbros, gabbros and ultramafic...... rocks collectively yield an Sm–Nd errorchron age of 2973 ± 28 Ma (MSWD = 33), with an average initial eNd = + 3.3 ± 0.7, consistent with a long-term depleted mantle source. Regression of Pb isotope data define an age of 2945 ± 36 Ma (MSWD = 44); and the regression line intersects the average growth...

    Poland's syndrome consists of the variable clinical features, but always includes unilateral aplasia of the chest wall muscles and ipsilateral anomalies of upper extremity. The incidence of Poland's syndrome, reported by different authors ranges from 1:10,000 to 1:100,000 and is observed more frequently in males than in females with the right side of the body affected more often than the left. The etiology of this syndrome is still discussed. However most of described cases were sporadic, rare familial incidence of Poland's syndrome were also presented. Therefore different etiologic factors of the Poland's syndrome are taken into account: genetic, vascular compromise during early stages of embriogenesis but also teratogenic effect of environmental xenobiotics (e.g. cigarette smoking by pregnant women). The authors present also the case of 20-years old man with inherited bilateral syndactyly with the right side aplasia of major pectoralis muscle and face asymmetry. The familial history was negative in respect to the features, associated with Poland's syndrome.

    Abyssal peridotites generate at mid-ocean ridges. Lherzolite and harzburgite are the main rock types of peridotites in the uppermost mantle. The lherzolite subtype, less depleted and less common in ophiolites, characterizes mantle diapirs and slow-spreading ridges. Along the Earth's mid-ocean ridges, abyssal peridotites undergo hydration reactions to become serpentinite minerals, especially in slow to ultraslow spreading mid-ocean ridges. Spinel is common in small quantities in peridotites, and its compositions have often been used as petrogenetic indicators [1]. The Southwest Indian Ridge (SWIR) is one of the two ultraslow spreading ridges in the world. The studied serpentinized peridotite sample was collected by the 21st Voyage of the Chinese oceanic research ship Dayang Yihao (aka Ocean No. 1) from a hydrothermal field (63.5°E, 28.0°S, and 3660 m deep) in SWIR. The studied spinels in serpentinized lherzolite have four zones with different compositions: relic, unaltered core is magmatic Al-spinels; micro- to nano- sized ferrichromite zoned particles; narrow and discontinuous magnetite rim; and chlorite aureoles. The values Cr# of the primary Al-spinels indicate the range of melting for abyssal peridotites from SWIR extends from ~4% to ~7% [2]. The alteration rims of ferrichromite have a chemical composition characterized by Fe enrichment and Cr# increase indicating chromite altered under greenschist-amphibolite facies. Magnetites formed in syn- and post- serpentinization. Chlorite (clinochlore) formed at the boundary and crack of spinel indicating it had undergone with low-temperature MgO- and SiO2-rich hydrothermal fluids [3]. It suggests that serpentinized lherzolite from SWIR had undergone poly-stage hydration reactions with a wide range of temperature.

  4. Subduction initiation and recycling of Alboran domain derived crustal components prior to the intra-crustal emplacement of mantle peridotites in the Westernmost Mediterranean: isotopic evidence from the Ronda peridotite

    During Late Oligocene-Early Miocene different domains formed in the region between Iberia and Africa in the westernmost Mediterranean, including thinned continental crust and a Flysch Trough turbiditic deposits likely floored by oceanic crust [1]. At this time, the Ronda peridotite likely constituted the subcontinental lithospheric mantle of the Alboran domain, which mantle lithosphere was undergoing strong thinning and melting [2] [3] coevally with Early Miocene extension in the overlying Alpujárride-Maláguide stacked crust [4, 5]. Intrusive Cr- rich pyroxenites in the Ronda massif records the geochemical processes occurring in the subcontinental mantle of the Alboran domain during the Late Oligocene [6]. Recent isotopic studies of these pyroxenites indicate that their mantle source was contaminated by a subduction component released by detrital crustal sediments [6]. This new data is consistent with a subduction setting for the late evolution of the Alboran lithospheric mantle just prior to its final intracrustal emplacement in the early Miocene Further detailed structural studies of the Ronda plagioclase peridotites-related to the initial stages of ductile emplacement of the peridotite-have led to Hidas et al. [7] to propose a geodynamic model where folding and shearing of an attenuated mantle lithosphere occurred by backarc basin inversion followed by failed subduction initiation that ended into the intracrustal emplacement of peridotite into the Alboran wedge in the earliest Miocene. This hypothesis implies that the crustal component recorded in late, Cr-rich websterite dykes might come from underthrusted crustal rocks from the Flysch and/or Alpujárrides units that might have been involved in the earliest stages of this subduction initiation stage. To investigate the origin of crustal component in the mantle source of this late magmatic event recorded by Cr-pyroxenites, we have carried out a detail Sr-Nd-Pb-Hf isotopic study of a variety of Betic

    Poland is an important case study in understanding the role of international cooperation in reducing the risk of global climate change. A the world's fourth largest coal producer, the nation occupies a key position in the political economy of a changing Europe. More importantly, Poland is pursuing energy policy reforms that half of the world must follow to reduce greenhouse gas emissions and prosper economically. Poland is undergoing profound economic and environmental change. This nation of 38 million people hopes to shift from planning to markets to allocate economic resources, and at the same time to conserve and protect environmental resources. Per capita incomes are only one-fourth of West Germany's, for example, but per capita energy use (and emissions of carbon dioxide) is just as high. High energy intensity causes much of Poland's serious air and water pollution. Economic efficiency could help reduce carbon and sulfur emissions, but the capital required to improve the energy infrastructure is scarce. The combination of these problems has reduced GNP per capita 9 percent over the last decade

  7. Reactive-brittle dynamics in peridotite alteration

    The interactions between reactive fluids and brittle solids are critical in Earth dynamics. Implications of such processes are wide-ranging: from earthquake physics to geologic carbon sequestration and the cycling of fluids and volatiles through subduction zones. Peridotite alteration is a common feature in many of these processes, which - despite its obvious importance - is relatively poorly understood from a geodynamical perspective. In particular, alteration reactions are thought to be self-limiting in nature, contradicting observations of rocks that have undergone 100% hydration/carbonation. One potential explanation of this observation is the mechanism of "reaction-driven cracking": that volume changes associated with these reactions are large enough to fracture the surrounding rock, leading to a positive feedback where new reactive surfaces are exposed and fluid pathways are created. The purpose of this study is to investigate the relative roles of reaction, elastic stresses and surface tension in alteration reactions. In this regard we derive a system of equations describing reactive fluid flow in an elastically deformable porous media, and explore them via a combination of analytic and numerical solutions. Using this model we show that the final stress state of a dry peridotite that has undergone reaction depends strongly on the rates of reaction versus fluid transport: significant fluid flow driven by pressure and/or surface tension gradients implies higher fractions of serpentinization, leaving behind a highly stressed residuum of partially reacted material. Using a model set-up that mimics a cylindrical triaxial apparatus we predict that the resulting stresses would lead to tensile failure and the generation of radially oriented cracks.

  8. Oceanic provenance of lithospheric mantle beneath Lower Silesia (SW Poland) and the two kinds of its "Fe-metasomatism"

    2016-04-01

    Our recent studies (Puziewicz et al. 2015, IJES 104:1913-1924, and references therein) show that the subcontinental lithospheric mantle (SCLM) beneath Lower Silesia (SW Poland) and neighbouring part of Upper Lusatia (SE Germany) is dominated by harzburgites. Part of them contain small amounts of clinopyroxene which, despite its primary textural appearance, is a late addition to the protoliths which are residues after extensive (up to 30 %) partial melting. This clinopyroxene was added to the harzburgites in Cenozoic times by alkaline basaltic melts migrating upwards from their asthenospheric sources during rifting in the Variscan foreland of the Alpine-Carpathian chain. The pre-rifting history of the SCLM beneath the region is thus recorded in the olivine and orthopyroxene. The forsterite content in olivine divides the Lower Silesian harzburgites into two groups: A (olivine Fo 90.5 - 92.0), and B (olivine Fo 84.0 - 90.0; for data see Puziewicz et al. 2015, op. cit.). The Al content in orthopyroxene is low and similar in both A and part of B harzburgites, called B1 in the following. The orthopyroxene occurring in the B1 harzburgites contains typically 0.05 - 0.10 atoms of Al per formula unit (corresponding to 0.5 - 2.5 wt. % Al2O3), although slightly lower (down to 0.02 a pfu) and slightly higher (up to 0.13 a pfu) Al contents occur in subordinate number of samples. The Al content in the B1 orthopyroxene is not correlated with forsterite content in coexisting olivine. The B2 harzburgites occur only in one site (Księginki). They contain orthopyroxene which Al content exhibits negative correlation with forsterite content in coexisting olivine. The most Al -rich orthopyroxene (0.24 atoms of Al pfu, corresponding to ca. 5.7 wt % Al2O3) coexists with olivine Fo 86.5 in Księginki. The low contents of Al in orthopyroxene is specific for the Lower Silesian/Upper Lusatian domain of European lithospheric mantle. The Al-poor mantle domain below Lower Silesia and upper

    2003-01-01

    The opaque mineralogy and the contents and isotope compositions of sulfur in serpentinized peridotites from the MARK (Mid-Atlantic Ridge, Kane Fracture Zone) area were examined to understand the conditions of serpentinization and evaluate this process as a sink for seawater sulfur. The serpentinites contain a sulfur-rich secondary mineral assemblage and have high sulfur contents (up to 1 wt.%) and elevated ??34Ssulfide (3.7 to 12.7???). Geochemical reaction modeling indicates that seawater-peridotite interaction at 300 to 400??C alone cannot account for both the high sulfur contents and high ??34Ssulfide. These require a multistage reaction with leaching of sulfide from subjacent gabbro during higher temperature (???400??C) reactions with seawater and subsequent deposition of sulfide during serpentinization of peridotite at ???300??C. Serpentinization produces highly reducing conditions and significant amounts of H2 and results in the partial reduction of seawater carbonate to methane. The latter is documented by formation of carbonate veins enriched in 13C (up to 4.5???) at temperatures above 250??C. Although different processes produce variable sulfur isotope effects in other oceanic serpentinites, sulfur is consistently added to abyssal peridotites during serpentinization. Data for serpentinites drilled and dredged from oceanic crust and from ophiolites indicate that oceanic peridotites are a sink for up to 0.4 to 6.0 ?? 1012 g seawater S yr-1. This is comparable to sulfur exchange that occurs in hydrothermal systems in mafic oceanic crust at midocean ridges and on ridge flanks and amounts to 2 to 30% of the riverine sulfate source and sedimentary sulfide sink in the oceans. The high concentrations and modified isotope compositions of sulfur in serpentinites could be important for mantle metasomatism during subduction of crust generated at slow spreading rates. ?? 2003 Elsevier Science Ltd.

    Oman Drilling Project hole BT1B drilled 300 meters through the basal thrust of the Samail ophiolite. The first 200 meters of this hole are dominated by listvenites (completely carbonated peridotites) and serpentinites. Below 200 meters the hole is mainly composed of metasediments and metavolcanics. This core provides a unique record of interaction between (a) mantle peridotite in the leading edge of the mantle wedge and (b) hydrous, CO2 rich fluids derived from subducting lithologies similar to those in the metamorphic sole. We used EQ3/6 to simulate a reaction path in which hydrous fluid in equilibrium with qtz + calcite + feldspar + chlorite or smectite reacts with initially fresh peridotite at 100°C (the estimated temperature of alteration, Falk & Kelemen GCA 2015) and 5 kb. Water was first equilibrated with minerals observed during core description in the metamorphic sole at 100°C and 5kb. This fluid is then reacted with olivine enstatite and diopside (Mg#90) approximating the average composition of residual mantle peridotite (harzburgite) in Oman. Secondary minerals resulting from complete reaction are then reacted again with the initial fluid in an iterative process, up to water/rock > 1000. Water/rock close to 1 results in complete serpentinization of the peridotite, with chrysotile, brucite and magnetite as the only minerals. Water/rock >10 produces carbonates, chlorite and talc. Further increasing water/rock to > 100 produces assemblages dominated by carbonates and quartz with minor muscovite, similar to listvenites of hole BT1B that contain qtz + carbonates + Fe-oxyhydroxides + relict spinel ± chromian muscovite and fuchsite. The results of this preliminary model are consistent with the complex veining history of core from BT1B, with carbonate/iron oxide veins in both listvenites and serpentinites interpreted to be the earliest record of peridotite carbonation after initial serpentinization.

  11. Peridotites and mafic igneous rocks at the foot of the Galicia Margin: an oceanic or continental lithosphere? A discussion

    2016-10-01

    An ultramafic/mafic complex is exposed on the sea floor at the foot of the Galicia Margin (Spain and Portugal). It comprises various types of peridotites and pyroxenites, as well as amphibole-diorites, gabbros, dolerites and basalts. For chronological and structural reasons (gabbros were emplaced within peridotites before the continental break-up) this unit cannot be assigned to the Atlantic oceanic crust. The compilation of all available petrological and geochemical data suggests that peridotites are derived from the sub-continental lithospheric mantle, deeply transformed during Cretaceous rifting. Thus, websterite dykes extracted from the depleted MORB mantle reservoir (DMM), were emplaced early within the lithospheric harzburgites; subsequent boudinage and tectonic dispersion of these dykes in the peridotites, during deformation stages at the beginning of rifting, resulted in the formation of fertile but isotopically depleted lherzolites. Sterile but isotopically enriched websterites, would represent melting residues in the peridotites, after significant partial melting and melt extraction related to the thermal erosion of the lithosphere. The latter melts are probably the source of brown amphibole metasomatic crystallization in some peridotites, as well as of the emplacement of amphibole-diorite dykes. Melts directly extracted from the asthenosphere were emplaced as gabbro within the sub-continental mantle. Mixing these DMM melts together with the enriched melts extracted from the lithosphere, provided the intermediate isotopic melt-compositions - in between the DMM and Oceanic Islands Basalts reservoir - observed for the dolerites and basalts, none of which are characterized by a genuine N-MORB signature. An enriched lithospheric mantle, present prior to rifting of the Galicia margin, is in good agreement with data from the Messejana dyke (Portugal) and more generally, with those of all continental tholeiites of the Central Atlantic Magmatic Province (CAMP

    2014-06-01

    Full Text Available This paper presents gravimetric and morphologic analyses based on the satellite-derived data set of EGM2008 and TOPEX for the area of the oceanic mantle massif of the Saint Peter and Saint Paul peridotite ridge, Equatorial Atlantic Ocean. The free-air anomaly indicates that the present plate boundary is not situated along the longitudinal graben which cuts peridotite ridge, but about 20 km to the north of it. The high Bouguer anomaly of the peridotite ridge suggests that it is constituted mainly by unserpentinised ultramafic rocks. The absence of isostatic compensation and low-degree serpentinisation of the ultramafic rocks indicate that the peridotite ridge is sustained mainly by active tectonic uplift. The unparallel relation between the transform fault and the relative plate motion generates near north-south compression and the consequent tectonic uplift. In this sense, the peridotite massif is a pressure ridge due to the strike-slip displacement of the Saint Paul Transform Fault.

    Full Text Available Introduction Geological background Ophiolites have played a major role in our understanding of Earth’s processes ranging from seafloor spreading, melt evolution and magma transport in oceanic spreading centers, and hydrothermal alteration and mineralization of oceanic crust to collision tectonics, mountain building processes, and orogeny. They provide the essential structural, petrological, geochemical, and geochronological evidence to document the evolutionary history of ancient continental margins and ocean basin. Ophiolites include a peridotitic mantle sequence, generally characterized by high-temperature plastic deformation and residual chemistry, and a comagmatic crustal sequence (gabbros, diabase dikes, and submarine basalts, weakly or not deformed. According to this interpretation, ophiolites were allochthonous with respect to their country rocks. They were assembled during a primary accretion stage at an oceanic spreading center, and later tectonically emplaced on a continental margin or island arc (Dilek, 2003. The indigenous dikes of pyroxenites and gabbros that were injected into a melting peridotite, or intrusive dikes of pyroxenite and gabbro that injected when the peridotite was fresh and well below its solidus, are discussed in different ophiolite papers. Pyroxenite formation and contact of gabbro and mantle peridotite are discussed in different articles (Dilek, 2003. When a gabbro intrude a fresh mantle peridotite could not significantly react with it, but if intrusion occurs during the serpentinization, the gabbro will change to rodingite. Geological setting The Naein ophiolitic melanges comprise the following rock units: mantle peridotites (harzburgite, lherzolite, dunite, with associated chromitite, gabbro, pyroxenite, sheeted and swarm dikes, massive basalts, pillow lava, plagiogranite, radiolarian chert, glaubotruncana limestone, rodingite, listvenite, and metamorphic rocks (foliated amphibolitic dike, amphibolite, skarn

    Eclogite component entrained in ascending plume is considered to be essentially important in producing flood basalts (e.g., Columbia River basalt, Takahashi et al., 1998 EPSL), alkalic OIBs (e.g., Kogiso et al.,2003), ferro-picrites (Tuff et al.,2005) and Hawaiian shield lavas (e.g., Hauri, 1996; Takahashi & Nakajima, 2002, Sobolev et al.,2005). Size of the entrained eclogite, which controls the reaction rates with ambient peridotite, however, is very difficult to constrain using geophysical observation. Among Hawaiian shield volcanoes, Koolau is the most enriched end-member in eclogite component (Frey et al, 1994). Reconstruction of Koolau volcano based on submarine study on Nuuanu landslide (AGU Monograph vol.128, 2002, Takahashi Garcia Lipman eds.) revealed that silica-rich tholeiite appeared only at the last stage (Makapuu stage) of Koolau volcano. Chemical compositions of lavas as well as isotopes change abruptly and coherently across a horizon (Shinozaki et al. and Tanaka et al. ibid.). Based on these observation, Takahashi & Nakajima (2002 ibid) proposed that the Makapuu stage lava in Koolau volcano was supplied from a single large eclogite block. In order to study melting process in Hawaiian plume, high-pressure melting experiments were carried out under dry and hydrous conditions with layered eclogite/peridotite starting materials. Detail of our experiments will be given by Gao et al (2015 AGU). Combined previous field observation with new set of experiments, we propose that variation in SiO2 among Hawaiian tholeiites represent varying degree of wall-rock interaction between eclogite and ambient peridotite. Makapuu stage lavas in Koolau volcano represents eclogite partial melts formed at ~3 GPa with various amount of xenocrystic olivines derived from Pacific plate. In other words, we propose that "primary magma" in the melting column of Hawaiian plume ranges from basaltic andesite to ferro-picrite depending on the lithology of the source. Solidus of

    One poorly constrained reservoir of the Earth's water budget is that of clinopyroxene in metasomatised, mantle peridotites. This study presents reconnaissance Sensitive High-Resolution, Ion Microprobe–Stable Isotope (SHRIMP–SI) determinations of the H2O contents of (dominantly) clinopyroxenes in rare mantle xenoliths from four different subduction zones, i.e. Mexico, Kamchatka, Philippines, and New Britain (Tabar-Feni island chain) as well as one intra-plate setting (western Victoria). All of the sub-arc xenoliths have been metasomatised and carry strong arc trace element signatures. Average measured H2O contents of the pyroxenes range from 70 ppm to 510 ppm whereas calculated bulk H2O contents range from 88 ppm to 3 737 ppm if the variable presence of amphibole is taken into account. In contrast, the intra-plate, continental mantle xenolith from western Victoria has higher water contents (3 447 ppm) but was metasomatised by alkali and/or carbonatitic melts and does not carry a subduction-related signature. Material similar to the sub-arc peridotites can either be accreted to the base of the lithosphere or potentially be transported by convection deeper into the mantle where it will lose water due to amphibole breakdown.

    Spinel peridotite, metamorphosed in high-pressure conditions, was first described within the Western part of the Central Asian Orogenic Belt. The spinel peridotite has the characteristics of Mg-Cr ultramafites indicating the mantle origin of its protolith. The preliminary estimation of the metamorphism peak for the model system MgO-Al2O3—SiO2-Cr2O3 (MASCr) is 10-19 kbar at 680-800°C.

  19. Transition Metal Systematics of Opx-Enriched Harzburgites From the Cascades Arc With Implications for the Origin of Cratonic Peridotites

    A number of peridotite xenoliths collected from the Simcoe volcanic field region of the Cascades arc exhibit notable enrichment of modal orthopyroxene. The process driving this enrichment is most likely metasomatism of the mantle wedge by Si-rich fluids derived ultimately from the underlying slab. By investigating the resultant elemental systematics associated with subduction zone metasomatism of this type, we hope to shed light on the origin of other opx-rich peridotites, such as those seen in many cratonic xenolith suites. The xenoliths found in the Simcoe volcanic field provide a rare opportunity to examine the composition of sub arc mantle, as it is unusual to find mantle xenoliths in volcanic arc lavas. The samples were analyzed using laser ablation ICPMS and their bulk compositions were reconstructed from point-counted mineral modes. Two-pyroxene mineral thermometry of the samples yield temperatures of approximately 1000 degrees C, corresponding to a depth of origin at uppermost mantle pressures if typical arc geotherms are assumed. Most of the peridotites are harzburgites or olivine-orthopyroxenites (Mg#s 0.88-0.9; opx mode 0.15-0.9), with small amounts of clinopyroxene (rare earths, consistent with a metasomatic origin for these opx-rich harzburgites. Of note is the counterintuitive systematics of Zn. Whole-rock Zn decreases with opx, but Zn in olivine also decreases with opx mode while Zn in opx increases with opx mode, hence the decrease in whole- rock Zn is not simply due to mechanical segregation of harzburgite into opx- and ol-rich zones. In summary, the REE signatures suggest the subducting slab as the most likely candidate for the source of the fluids that caused the opx enrichment. The opx-enrichment itself and the unusual trends in Zn suggest a reaction between a silicic fluid and normal harzburgite. Moreover, the concomitant decrease in olivine and whole-rock Zn with opx mode suggests significant leaching of Zn from the peridotite during this

    Mantle peridotites drilled from the Izu-Bonin-Mariana forearc have unradiogenic 187Os/188Os ratios (0.1193 to 0.1273), which give Proterozoic model ages of 820 to 1230 million years ago. If these peridotites are residues from magmatism during the initiation of subduction 40 to 48 million years ago, then the mantle that melted was much more depleted in incompatible elements than the source of mid-ocean ridge basalts (MORB). This result indicates that osmium isotopes record information about ancient melting events in the convecting upper mantle not recorded by incompatible lithophile isotope tracers. Subduction zones may be a graveyard for ancient depleted mantle material, and portions of the convecting upper mantle may be less radiogenic in osmium isotopes than previously recognized.

    Piston-cylinder experiments with natural rocks and mineral separates were carried out at 750-900 °C and 2.9 GPa, conditions relevant to hot subduction zones, to study the mechanisms of metasomatic alteration of mantle-wedge rocks such as dunite and lherzolite, and the transfer of trace elements released from a carbonate-bearing amphibolite during its eclogitization. Element transfer from the slab to the mantle lithologies occurred in porous-, focused- and diffusive-flow regimes that remove melt and carbon, and partially water, from the metabasite layer. Porous flow is recorded by dissolution of clinopyroxene and growth of orthopyroxene ± garnet ± magnesite ± chlorite along grain boundaries in the peridotite layers, but is invisible in the metabasite layers. Porous flow of the same fluids/melts produces harzburgite mineralogy in both dunite and lherzolite. The transformation of lherzolite to harzburgite reflects breakdown of clinopyroxene in the lherzolite and diffusion of the liberated calcium into the metabasite layer, i.e. against the direction of major fluid/melt flow. Focused flow develops along the side walls of the capsules, producing a melt-free omphacite ± phengite ± quartz paragenesis in the metabasite, and melt segregations, separated from the host peridotite layers by newly-formed omphacite ± garnet ± phlogopite + orthopyroxene + magnesite. Diffusive flow leads to the formation of orthopyroxene ± magnesite ± garnet reaction zones at the metabasite-peridotite interface and some melt-peridotite interfaces. Melt segregations in the peridotite layers at 850-900 °C are rich in LREE and LILE, strongly depleted in Y and HREE, and have higher Sr/Y and La/Yb ratios than island arc andesites, dacites and rhyolites. These features, and negative anomalies in Nb-Ta and low Nb/Ta, resemble those of high-silica adakites and TTGs, but K2O is high compared to TTGs. Metasomatism in the dunite layer changes the REE patterns of dunite, recording chromatographic

    The peridotite aquifer in Wadi Tayin, Sultanate of Oman, is a perfect example of natural carbonation of ultramafic rocks. In situ mineral carbonation is considered the most safest and permanent option of CO2 Capture and Sequestration (CCS). However, the process itself is yet to be characterised and a better understanding of the mechanisms involved in natural mineral carbonation is needed before geo-engineering it. We used the 87Sr/86Sr system to follow the water-rock interactions along the groundwater flowpath in the peridotite aquifer and to determine the sources of divalent cations (Mg2+, Ca2+) required for mineral carbonation. The Sr-isotope data of groundwater show that the aquifer rocks are the main source for divalent cations (Mg2+, Ca2+ and Sr2+) and secondary carbonates are their main sink. The groundwater 87Sr/86Sr ratio evolves with its pH: from 87Sr/86Sr = 0.7087 (n=3) to 0.7082 (n=8) between pH 7 and 8, and from 0.7086 (n=6) at pH 9 to 0.07075 (n=9) at pH 11. This evolution seems to support a two-step model for the water-rock interactions in the peridotite aquifer. From pH 7 to 8, secondary Ca-carbonate precipitation buffers the pH rise resulting from peridotite serpentinisation. From pH 9 to 11, peridotite serpentinisation drives the pH to alkaline condition. The change from a Mg-rich to a Ca-rich groundwater at pH 9 seems to confirm the two-step model.

    Strong thermal and chemical gradients are characteristic of the slab-mantle interface in subduction zones where relatively cold sediments become juxtaposed with hotter peridotite of the mantle wedge. The formation of arc magmas is directly related to mass transfer processes under these conditions. We have undertaken a series of experiments to simulate interactions and mass transfer at the slab-mantle interface. In addition to having juxtaposed sediment and peridotite layers, the experiments were performed under different thermal gradients. The sediment had a composition similar to GLOSS (1) and also served as the source of H2O, CO2 and a large selection of trace elements. The peridotite was a depleted garnet harzburgite formed from a mixture of natural hand-picked olivine, opx and garnet. Graphite was added to this mixture to establish a redox gradient between the two layers. Experiments were performed at 7.5-10 GPa to simulate the processes during deep subduction. The thermal gradient was achieved by displacing the sample capsule (Re-lined Pt) from the center of the pressure cell. The gradient was monitored with separate thermocouples at each end of the capsule and by subsequent opx-garnet thermometry across the sample. Maximum temperatures varied from 1400˚ -900˚ C and gradients ranged from 200˚ -800˚ C. Thus, in some experiments melting occurred in the sediment layer and in others this layer remained subsolidus, only devolatilizing. Major and trace elements were transported both in the direction of melt percolation to the hot zone, as well as down temperature. This leads to the development of zones with discrete phase assemblages. Olivine in the peridotite layer becomes converted to orthopyroxene, which is due to Si addition, but also migration of Mg and Fe towards the sediment. In the coldest part of a sample, the sediment is converted into an eclogitic cpx + garnet assemblage. A thin zone depleted in almost all trace elements is formed in peridotite

  4. The production of iron oxide during peridotite serpentinization: Influence of pyroxene

    Full Text Available Serpentinization produces molecular hydrogen (H2 that can support communities of microorganisms in hydrothermal fields; H2 results from the oxidation of ferrous iron in olivine and pyroxene into ferric iron, and consequently iron oxide (magnetite or hematite forms. However, the mechanisms that control H2 and iron oxide formation are poorly constrained. In this study, we performed serpentinization experiments at 311 °C and 3.0 kbar on olivine (with <5% pyroxene, orthopyroxene, and peridotite. The results show that serpentine and iron oxide formed when olivine and orthopyroxene individually reacted with a saline starting solution. Olivine-derived serpentine had a significantly lower FeO content (6.57 ± 1.30 wt.% than primary olivine (9.86 wt.%, whereas orthopyroxene-derived serpentine had a comparable FeO content (6.26 ± 0.58 wt.% to that of primary orthopyroxene (6.24 wt.%. In experiments on peridotite, olivine was replaced by serpentine and iron oxide. However, pyroxene transformed solely to serpentine. After 20 days, olivine-derived serpentine had a FeO content of 8.18 ± 1.56 wt.%, which was significantly higher than that of serpentine produced in olivine-only experiments. By contrast, serpentine after orthopyroxene had a slightly higher FeO content (6.53 ± 1.01 wt.% than primary orthopyroxene. Clinopyroxene-derived serpentine contained a significantly higher FeO content than its parent mineral. After 120 days, the FeO content of olivine-derived serpentine decreased significantly (5.71 ± 0.35 wt.%, whereas the FeO content of orthopyroxene-derived serpentine increased (6.85 ± 0.63 wt.% over the same period. This suggests that iron oxide preferentially formed after olivine serpentinization. Pyroxene in peridotite gained some Fe from olivine during the serpentinization process, which may have led to a decrease in iron oxide production. The correlation between FeO content and SiO2 or Al2O3 content in olivine- and

    Exposures of serpentinized peridotites on the seafloor at slow-spreading ridges have been interpreted either as accretion of ridge segments in a magma-starved condition along the non-transform setting or as preferential outcrops at ridge offsets in transform fault setting. Here we present the mineral chemistry and geochemistry of serpentinites and serpentinized spinel peridotites recovered from an off axis region (corner high) at south of Vityaz transform fault (6°39'S), Northern Central Indian Ridge. Our purpose is to use mineral chemical data of serpentine and spinel to investigate the effect of low temperature alteration processes and degree of partial melting. Serpentine composition shows presence of high Mg-rich lizardite and chrysotile pseudomorphs and these rocks mostly preserve `mesh rim', `window' and `hourglass' textures, representing extensive hydration during low temperature hydrothermal alteration. In thin section, serpentine veins (mainly lensoidal, pinch and swell or anastomosing) are common, sometime crosscutting the `mesh rim' textures to attest to the intensity of serpentinization process. In one sample, a 1.9 cm-thick feldspathic vein crosscut the serpentinite as a porphyroblast and this indicates discontinuity in magmatic crust caused due to less magma input at off-axis region facilitate the intrusion of short-living feeder dykes of highly fractionated late magmatic liquids within the peridotite. In addition, in hand specimen, presence of smaller-scale striations analogous to slickenlines on serpentinite surfaces suggests low-angle faulting, which could have enhanced pervasive serpentinization during their subsequent emplacement. Individual serpentine grain displays very low Ca content (0.01 wt%) suggesting possible absence of any secondary Ca-rich phases also verified by very low Sr content (connotation. Limited data on composition of individual spinel porphyroclast exhibits substantial variation in their Mg# (mole [Mg/ Mg+Fe2]) and Cr# (mole

    Full Text Available Introduction Study of the petrology of the ophiolites as the relics of ancient oceanic lithosphere, is a powerful tool to reconstruct Earth’s history. Mantle peridotites have mostly undergone alteration and serpentinization to some extent. Thus, the relics of metamorphic signatures from the upper mantle and crustal processes from most of the peridotites have been ruined. Several recent papers deal with the mantle peridotites of Nain Ophiolite (e.g. Ghazi et al., 2010. However, no scientific work has been carried out on the metamorphosed mantle peridotites. The study area of the Darreh Deh that is located in the east of the Nain Ophiolite, is composed of huge massifs of metamorphosed mantle peridotites (i.e. lherzolite, clinopyroxene-bearing harzburgite, and harzburgite, and small volumes of dunite, characterized by darker color, higher topographic relief, smaller number of basic intrusives, lower serpentinization degree, and amphibolite-facies metamorphism. In this study, the petrography and mineralogy of metamorphosed peridotites in the Darreh Deh has been considered based on geochemical data. Geological Setting The Mesozoic ophiolitic mélange of Nain is located in the west of CEIM, along the Nain-Baft fault. As a part of a metamorphosed oceanic crust, it is mainly composed of harzburgite, lherzolite, dunite and their serpentinized varieties, chromitite, pyroxenite, gabbro, diabasic dike, spilitized pillow lava, plagiogranite, amphibolite, metaperidotites, schist, skarn, marble, rodingite, metachert and listwaenite (Shirdashtzadeh et al., 2010, 2014a, 2014b.

    The Piranshahr metaperidotites in the northwestern end of the Zagros orogen were emplaced following the closure of the Neotethys ocean. The ophiolitic rocks were emplaced onto the passive margin of the northern edge of the Arabian plate as a result of northeastward subduction and subsequent accretion of the continental fragments. The metaperidotites have compositions ranging from low-clinopyroxene lherzolite to harzburgite and dunite. They are mantle residues with distinct geochemical signatures of both mid-ocean ridge and supra subduction zone (SSZ) affinities. The abyssal peridotites are characterized by high Al2O3 and Cr2O3 contents and low Mg-number in pyroxenes. The Cr-number in the coexisting spinel is also low. The SSZ mantle peridotites are characterized by low Al2O3 contents in pyroxenes as well as low Al2O3 and high Cr-number in spinel. Mineral chemical data indicate that the MOR- and SSZ-type peridotites are the residues from ∼15-20% and ∼30-35% of mantle melting, respectively. Considering petrography, mineralogy and textural evidence, the petrological history of the Piranshahr metaperidotites can be interpreted in three stages: mantle stable stage, serpentinization and metamorphism. The temperature conditions in the mantle are estimated using the Ca-in-orthopyroxene thermometer as 1210 ± 26 °C. The rocks have experienced serpentinization. Based on the textural observations, olivine and pyroxene transformed into lizardite and/or chrysotile with pseudomorphic textures at temperatures below 300 °C during the initial stage of serpentinization. Subsequent orogenic metamorphism affected the rocks at temperatures lower than 600 °C under lower-amphibolite facies metamorphism.

  10. Pathways of geomorphic evolution of sandstone escarpments in the Góry Stołowe tableland (SW Poland) - Insights from LiDAR-based high-resolution DEM

    The tableland of the Stołowe Mountains (SW Poland), with its prominent mesas and sandstone-capped escarpments, belongs to the most spectacular geomorphic landscapes of Central Europe. While the gross morphological features of the area have long been recognized, the evolutionary pathways of densely forested and poorly accessible escarpment slopes remained poorly understood. In this paper we use LiDAR data to shed a new light on landform inventories within the escarpments, their spatial patterns and, using process-from-form reasoning, on the longer-term evolution of the escarpments. Four sites, two on each major escarpment, have been subject to detailed analysis which involved examination of shaded relief, slope, plan and profile curvature and topographic wetness index. In each case, the 1 × 1 m model was used, while for the most complex site at Mt. Szczeliniec Wielki the results were compared with the 5 × 5 m model to check the impact of model resolution on geomorphic interpretation. Despite some loss of information involved in model re-interpolation to the coarser scale, the main features of escarpment morphology could still be recognized. On the other hand, automatic landform classification based on the calculation of Topographic Position Index from the 10 × 10 m model and performed for the entire tableland failed to reveal differences between various sections of the escarpments, detectable on finer models. The analysis of spatial patterns of minor landforms within the escarpments, identified on LiDAR-derived models shows that no single pathway of escarpment evolution exists. Both the upper slopes (in sandstone caprock) and the mid-slopes (in weaker rocks) show signs of instability and these are not necessarily coupled. Large-scale caprock failures do occur but seem rare and localized. Sandstone free faces are rather subject to continuous slow retreat by detachment of individual joint-bound blocks. Another zone of instability occurs well below the caprock and

    Around 1/3 of Earth's divergent ridge system is now classified as "slow" spreading [1], exposing ultramafic rocks (abyssal peridotites) at the seafloor. Such material is often highly altered by serpentinisation and steatisation (talc formation). It is crucial to understand such processes in order to access the original composition of the mantle, and to quantify any impact on ocean composition. Here we examine the effect of both serpentinisation and steatisation on Si, Mg and Zn isotopes. Hydrothermal alteration and seafloor weathering are both sources of oceanic Si [2] and weathering of abyssal peridotites is a source of oceanic Mg [3]; hence isotopic fractionation as a result of seafloor alteration could affect oceanic Si and Mg isotope composition. Zinc isotopes can provide complimentary information; the magnitude and direction of fractionation is highly dependent on complexing ligand [4] and can provide compositional information on the fluids driving metasomatism. For this study, two cores from the well-characterised abyssal peridotites recovered on ODP Leg 209 were examined [5]. Hole 1274a peridotites exhibit variable serpentinisation at ~200°C, whereas samples from Hole 1268a have been comprehensively serpentinised and then subsequently steatised to talc facies at ~350°C, by a low Mg/Si, low pH fluid. The Si, Mg and Zn isotope compositions of 1274a samples are extremely homogeneous, identical to that of pristine mantle rocks (BSE) i.e., serpentinisation at this locality was predominantly isochemical [5]. In contrast, samples from 1268a show greater isotopic variability. In all samples, Mg is enriched in the heavier isotopes relative to BSE, consistent with formation of isotopically heavy secondary phases [6]. For Si, serpentinised samples are slightly enriched in the lighter isotopes compared to BSE, again consistent with the behaviour of Si during formation of secondary phases [7]. Within the steatised samples, some exhibit enrichments in the lighter Si

    The chemical composition of liandratite, U6+(Nb,Ta)2O8, was determined from material collected in Niobium, Yttrium, Fluorine type (NYF) pegmatites of the Karkonosze intrusion (Sudetes, SW Poland). Liandratite occurs mainly as rims, up to 40 µm thick, and fracture infillings in fergusonite-(Y) and other Nb-Ta-Ti minerals. Its formation was related to the fluid-driven alteration of primary minerals by three potential mechanisms: (i) direct replacement of a primary mineral by liandratite; (ii) breakdown of the primary mineral to liandratite and a product with the composition of minerals of the pyrochlore group; (iii) multistage alteration, which involved: removal of A-site cations (mostly Y + REE with the exception of U4+) and formation of phases with the composition of pyrochlore group minerals; then crystallization of U-, Bi-, Pb-rich pyrochlores and their replacement by liandratite. The chemical compositions of liandratite formed by the breakdown of different primary minerals are also different, mainly in their U, Ti and Nb contents. Excess Ti, relative to the U6+Nb2O8 end-member, is incorporated into the structure together with additional U. The Ti content of liandratite, and partially through this the U content, are dependent on the nature of the precursor mineral.

    The aim of this study is to present the epidemiology of salmonellosis in Poland in 2010. The study was based on data from: "the Infectious diseases and poisonings in Poland 2010", information from laboratories based in sanitary stations, the forms of outbreaks investigations conducted by sanitary stations and data from Demographic Surveys Departament based in the Central Statistical Office. All cases were classified according to the case definition used by surveillance. A total of9 732 salmonellosis cases were reported in Poland. Among them 8 549 cases were intestinal and 183 were extraintestinal. The incidence rate was 25.5 per 100 000 inhabitants. Over 95% of cases met the criteria for a confirmed case. The number of registered cases was higher than in the previous two years, despite this an overall decreasing trend was observed in the number of cases of salmonellosis in Poland. Cases of salmonellosis occurred primarily among children under 5-years old. There were no deaths reported due to salmonellosis. There is still a high percentage, about 70%, hospital admissions of people infected with zoonotic Salmonella. The percentage of hospitalization in outbreaks is almost two and a half times lower -29%. In 2010, 189 outbreaks caused by Salmonella were reported, affecting 1 662 people (almost 18% of all reported cases of intestinal salmonellosis). Most were small family outbreaks. Still the most common etiologic agent in Poland is S. Enteritidis. When compared with previous years, in 2010 there was an increase in the number of cases caused by S. Mbandaka, S. Infantis and S. Virchow. The number of screening tests for carriers among food handlers decreased by over 10% however the percentage diagnosed with positive result increased from 0.3% to 0.5%. Human salmonellosis is still a significant public health problem in Poland. The very high percentage (70%) of hospitalization, persisting for many years indicates that diagnosis and reporting ofsalmonellosis in Poland is

    In 2004, Poland has adopted the WHO goal of rubella elimination and congenital rubella syndrome prevention. The main target of the Programme is to stop transmission of the virus in the environment and prevention of congenital rubella in children. This can be achieved by carrying out the vaccination. Participation in the rubella elimination program requires clinical diagnosis of rubella cases and their confirmation with laboratory test. In Poland, until 2003, national vaccination recommendation included a dose of rubella vaccine only for girls aged 13 years. Among men, the incidence of measles remained high creating a risk of infection of non-immune pregnant women which may lead to the development of congenital rubella syndrome in the child. To assess epidemiological situation of rubella in Poland in 2013, including vaccination coverage in Polish population. The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletins "Infectious diseases and poisonings in Poland in 2013" and "Vaccinations in Poland in 2013" (MP. Czarkowski, Warszawa 2014, NIZP-PZH, GIS). In 2013, there was big epidemic of rubella in Poland--with 38,548 registered cases (6 times more than in 2012), incidence 84.4 per 100,000 (5 times higher than in the previous year). The highest incidence rate, regardless of gender and the environment, was observed among adolescents aged 15-19 years (911.6 per 100,000). The incidence of rubella in boys and men was significantly higher than the incidence in girls and women (181.4 versus 23.9). In 2013, two cases of congenital rubella syndrome were registered. Rubella epidemic which occurred in Poland in 2013 was the result of use in the past vaccination against rubella only for girls 13 years of age. The proportion of laboratory tests confirming/excluding rubella infection is still very low in Poland. In 2013, only 0.2% of rubella cases were laboratory confirmed.

    Olivine crystallographic preferred orientation (CPO) is thought to be the main cause of seismic anisotropy in the mantle, and its formation is generally considered to be the result of plastic deformation of mantle by dislocation creep. Olivine CPO has been reproduced in laboratory deformation experiments and considerable success has been achieved in understanding the deformation conditions (e.g. stress, temperature and water content) under which different olivine CPO patterns develop. This opens the possibility of mapping conditions in the mantle using seismic anisotropy and has been the subject of considerable study. Here we report an alternative mechanism for olivine CPO without the need for deformation. This process may be important in understanding the seismic properties of mantle in convergent margins. Metamorphic studies show peridotite in the Happo area, central Japan, formed by the dehydration of antigorite-schist related to contact metamorphism around a granite intrusion. Both field and microstructural observations suggest the olivine has not undergone strong plastic deformation. This was confirmed by TEM work that shows the olivine has very low dislocation densities and lacks low angle tilt boundaries. Such tilt boundaries are general stable even after annealing. These features show that peridotite in the Happo area formed in the absence of solid-state deformation. The olivine of the Happo peridotite formed dominantly by the dehydration breakdown of antigorite schist. We propose that the olivine CPO formed as a result of topotactic replacement of antigorite by the newly formed olivine. EBSD measurements in samples where both antigorite and new olivine are present and in contact show a very close crystallographic relationship between the two minerals: the a-axes are parallel, and the b- and c-axes are perpendicular. We conclude the strong olivine CPO in the Happo area was inherited from the original CPO of the antigorite. Such a process is likely to also

    Full Text Available Purpose: This study examines the determinants of ex-ante state capture in Poland. Methodology: In order to establish the determinants of ex-ante state capture a logistic regression is estimated. Findings: The study shows that in Poland the majority of legal acts were passed with the aim to satisfy the interest of particular groups. Furthermore, the regression analysis shows that the likelihood of state capture increases during the period of higher economic growth and local elections. The likelihood of state capture, however, declines during presidential elections. The results we attribute to different interests of political parties in the period of local and presidential elections. Finally, we fi nd that the state capture increased over the years in Poland. Additionally, we show that the EU accession did not prevent state capture in Poland. In contrast, the fi nancial crisis of 2007 resulted in a wake-up effect and the likelihood of state capture declined in Poland. Research limitations: In the study we employ proxies for state capture, yet we assume that corruption is a widespread phenomenon in Poland. However, due to its nature corruption is very diffi cult to assess and measure. Originality: The study uses a unique dataset on ex-ante state capture that was identifi ed in the legal acts that have been passed in the period 1990–2011 in Poland.

    A 2-year study (2010-2011) of fluorides in atmospheric precipitation in the open area and in throughfall in Wielkopolski National Park (west-central Poland) showed their high concentrations, reaching a maximum value of 2 mg/l under the tree crowns. These high values indicate substantial deposition of up to 52 mg/m(2)/year. In 2011, over 51% of open area precipitation was characterized by fluoride concentration higher than 0.10 mg/l, and in throughfall such concentrations were found in more than 86% of events. In 2010, a strong connection was evident between fluoride and acid-forming ions, and in 2011, a correlation between phosphate and nitrite ions was seen. Analysis of available data on F(-) concentrations in the air did not show an unequivocal effect on F(-) concentrations in precipitation. To find reasons for and source areas of high fluoride pollution, the cases of extreme fluoride concentration in rainwater were related to atmospheric circulation and weather patterns. Weather conditions on days of extreme pollution were determined by movement of weather fronts over western Poland, or by small cyclonic centers with meteorological fronts. Macroscale air advection over the sampling site originated in the western quadrant (NW, W, and SW), particularly in the middle layers of the troposphere (2,500-5,000 m a.s.l.). Such directions indicate western Poland and Germany as possible sources of the pollution. At the same time in the lower troposphere, air inflow was frequently from the north, showing short distance transport from local emitters, and from the agglomeration of Poznań.

    Full Text Available Poland and Ukraine are the two biggest and most populated countries of Central and Eastern Europe. Because of their size, neighbourhood and position in the region the two countries have often been compared to France and Germany. Both countries are deeply interested in their mutual cooperation. Such situation steams from five factors: direct neighbourhood, common (albeit difficult history, attractiveness of the Polish labour market for the Ukrainians, membership of Poland in the Western structures, and last but not least, the Russian threat. Despite complimentary interests, both countries have difficulty to effectively develop their mutual relations and turn them into a real “strategic partnership”. These problems are due to the internal political and economic situation in Ukraine, limits imposed by the membership of Poland in the EU, Russian policy aiming at keeping Ukraine within its zone of influence and, finally, the EU reluctance to effectively engage in Ukraine.

    Vaccination against mumps, introduced initially as recommended, from 2003 is mandatory in Poland and given as two dose scheme with MMR vaccine (mumps, measles, and rubella). Despite observed decline in mumps incidence for over a decade which is a result of conducted vaccinations, mumps is still a common childhood disease in Poland. To assess epidemiological situation of mumps in Poland in 2012, including vaccination coverage in Polish population, in comparison to previous years. The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletins "Infectious diseases and poisonings in Poland in 2012" and "Vaccinations in Poland in 2012" (Czarkowski MP i in., Warszawa 2013, NIZP-PZH i GIS). Mumps cases were classified according to the criteria of surveillance case definition implemented in the European Union (Commission Decision of 28 April 2008 amending Decision 2002/253/EC). National Immunisation Programme for year 2012 was also used. In total, there were 2779 mumps cases registered in Poland in 2012. Incidence of mumps was 7.2 per 100 000 and it was higher by 7.5% in comparison with 2011 and lower by 19.4% in comparison to median for the years 2006-2010. The highest incidence rate was observed among children aged 5 years (71.8 per 100 000). Incidence in women (5.9) was lower than in men (8.6). In 2012, 25 people were hospitalized due to mumps. Vaccination coverage of children aged 3 years in Poland in 2012 was 97.9%. Systematic execution of mumps vaccination in accordance with the National Immunisation Programme resulted in a significant decrease in the number of registered cases. Due to the high vaccination coverage further decline in the number of cases is expected.

    A number of chickenpox cases, occurring especially in children, indicates the rationale for the use of chickenpox vaccinations. In Poland since 2002, chickenpox vaccination is included in the National Immunisation Programme as recommended. To assess epidemiological situation of chickenpox in Poland in 2012 in comparison to previous years. The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletins "Infectious diseases and poisonings in Poland in 2012" and "Vaccinations in Poland in 2012" (Czarkowski MP i in., Warszawa 2013, NIZP-PZH i GIS). National Immunisation Programme for year 2012 was also used. In 2012, 208 276 cases of chickenpox were registered in Poland. The highest number of cases was reported in Śląskie voivodeship, the lowest in Podlaskie voivodeship. Mumps incidence was 540.5 per 100 000 and was higher than in 2011 (448.7). The highest incidence was recorded in children aged 4 years (7 611.5 per 100 000). The chickenpox incidence among men (570.7) was higher than among women (512.2). The incidence among rural residents (553.9) was higher than among urban residents (531.8). Number of cases hospitalized due to mumps was 1 361. Number of people vaccinated against chickenpox was 56 213. In 2012, there was an increase in the incidence of smallpox in Poland. This trend is continuing since 2004, which can be partly explained by improved surveillance of the disease.

    The aim of this study was to assess the epidemiology of meningitis and/or encephalitis in Poland in 2014. In the last three years in Poland, about 3000 cases of meningitis and/or encephalitis of viral or bacterial etiology were recorded annually. Assessment of the epidemiological situation of meningitis and/or encephalitis in Poland in 2014, was based on the results of the analysis of epidemiological reports sent to the NIZP-PZH by the Regional Sanitary-Epidemiological Stations published in the annual bulletin “Infectious diseases and poisonings in Poland in 2014” and “Preventive immunizations in Poland in 2014”. In 2014 in Poland 3488 cases of bacterial meningitis and/or encephalitis were recorded. Almost 61.3% of these were viral infections. In 2014, in comparison to 2013, a 1.1% increase in the number of cases of meningitis and/or encephalitis was observed and 91% with viral etiology.

    At slow spreading ridges, axial detachment faults exhume mantle-derived peridotites. Their interaction with seawater-derived hydrothermal fluids causes serpentinization down to 2-3km from the fault, as inferred from seismic velocity models. It is commonly proposed that fractures allow penetration of seawater into the fault's footwall. At the microscopic scale, the hydration front progresses from a microfracture network toward the center of olivine relicts and forms the serpentine mesh texture. The origin of these microfractures is a matter of debate: tectonic, anisotropic thermal contraction of olivine during peridotite cooling or hierarchical fracturing of the olivine due to volume increase during serpentinization. In this presentation we use petrology and geochemistry to analyze the links between microfractures and serpentinization in a set of highly serpentinized peridotites dredged along the melt-starved easternmost part of the Southwest Indian Ridge (Smoothseafloor cruise). Our observations suggest that thermal contraction of olivine combines with tectonic stresses to fracture fresh peridotite in the brittle lithosphere. These ~60μm-spaced microfractures constitute the initial sample-scale permeability network for fluid penetration, onset of serpentinization and formation of additional hierarchical fractures. As serpentinization proceeds, the volume increase closes the least-developed planes and preferential pathways for fluid circulation become more distant, forming the 200-500μm-wide polygonal pattern typical of the serpentine mesh texture. In about 20% of the recovered samples the mesh serpentine is partially recrystallized forming rims next to later microfractures and serpentine veins. The spacing of these rims, and the limited proportion of affected samples suggest that the scales of the efficient permeability network in the serpentinites at this stage had increased to decimetric and greater scales. We use geochemical constrains to derive temperature

National Immunisation Programme for year 2013 was also used. In 2013, 178 501 cases of chickenpox were registered in Poland. The incidence was 463.6 and was lower than in 2012 (540.5). The highest number of cases was reported in mazowieckie voivodeship, the lowest in podlaskie voivodeship. The highest incidence was recorded in children aged 4 years (6 545.1 per 100,000). The chickenpox incidence among men (491.7) was higher by 12.4% comparing to women (437.3). The incidence among rural residents (497.2) was higher than among urban residents (441.7). Number of cases hospitalized due to mumps was 1 184. Number of people vaccinated against chickenpox was 57 168. In 2013, there was decrease in the incidence of chickenpox [corrected] in Poland with small fluctuations. Since 2002 the number of people vaccinated against chickenpox increased. The increase in the number of people vaccinated against chickenpox would help maintain the downward trend in subsequent years.

    Hydrogen is present as a trace element in olivine and pyroxene and its content distribution in the mantle results from melting and metasomatic processes. Here we examine how these H contents can be disturbed during decompression. Hydrogen was analyzed by FTIR in olivine and pyroxene of spinel peridotite xenoliths from Salt Lake Crater (SLC) nephelinites which are part of the rejuvenated volcanism at Oahu (Hawaii) [1,2]. H mobility in pyroxene resulting from spinel exsolution during mantle upwelling Most pyroxenes in SLC peridotites exhibit exsolutions, characterized by spinel inclusions. Pyroxene edges where no exsolution are present have less H then their core near the spinel. Given that H does not enter spinel [3], subsolidus requilibration may have concentrated H in the pyroxene adjacent to the spinel exsolution during mantle upwelling. H diffusion in olivine during xenolith transport by its host magma and host magma ascent rates Olivines have lower water contents at the edge and near fractures compared to at their core, while the concentrations of all other chemical elements appear homogeneous. This suggests that some of the initial water has diffused out of the olivine. Water loss from the olivine is thought to occur during host-magma ascent and xenolith transport to the surface [4-6]. Diffusion modeling matches best the data when the initial water content used is that measured at the core of the olivines, implying that mantle water contents are preserved at the core of the olivines. The 3225 cm(sup -1) OH band at times varies independantly of other OH bands, suggesting uneven H distribution in olivine defects likely acquired during mantle metasomatism just prior to eruption and unequilibrated. Diffusion times (1-48 hrs) combined with depths of peridotite equilibration or of magma start of degassing allow to calculate ascent rates for the host nephelinite of 0.1 to 27 m/s.

    Though extensively studied, the roles of olivine crystal preferred orientations (CPOs or fabrics) in affecting the seismic anisotropies in the Earth's upper mantle are rather complicated and still not fully known. In this study, we attempted to address this issue by analyzing the seismic anisotropies [e.g., P-wave anisotropy (AVp), S-wave polarization anisotropy (AVs), radial anisotropy (ξ), and Rayleigh wave anisotropy (G)] of the Songshugou peridotites (dunite dominated) in the Qinling orogen in central China, based on our previously reported olivine CPOs. The seismic anisotropy patterns of olivine aggregates in our studied samples are well consistent with the prediction for their olivine CPO types; and the magnitude of seismic anisotropies shows a striking positive correlation with equilibrium pressure and temperature (P-T) conditions. Significant reductions of seismic anisotropies (AVp, max. AVs, and G) are observed in porphyroclastic dunite compared to coarse- and fine-grained dunites, as the results of olivine CPO transition (from A-/D-type in coarse-grained dunite, through AG-type-like in porphyroclastic dunite, to B-type-like in fine-grained dunite) and strength variation (weakening: A-/D-type → AG-type-like; strengthening: AG-type-like → B-type-like) during dynamic recrystallization. The transition of olivine CPOs from A-/D-type to B-/AG-type-like in the forearc mantle may weaken the seismic anisotropies and deviate the fast velocity direction and the fast S-wave polarization direction from trench-perpendicular to trench-oblique direction with the cooling and aging of forearc mantle. Depending on the size and distribution of the peridotite body such as the Songshugou peridotites, B- and AG-type-like olivine CPOs can be an additional (despite minor) local contributor to the orogen-parallel fast velocity direction and fast shear-wave polarization direction in the orogenic crust such as in the Songshugou area in Qinling orogen.

    Poland started the works on construction of first nuclear power plant in 1992. The social protest as well as deep political and economical changes in Poland induced the decision of the Polish government to abandon the construction of the nuclear power plant in Zarnowiec. After the period of political and economical transformation, in 1992 Polish economy starts to grow up, also growth of the electric power consumption. Are there prospect for utilization in Poland the nuclear power plant? This work is devoted to analyse such question. The present structure of power and fuel materials in Poland were analysed and the possible direction of changes was shown for the period up to 2020 year. It was stated, that the economical development in Poland should be bound with the growth of the consumption of most effective fuel and energy. These fuel or energy should be imported to Poland. Therefore, the nuclear power should be treated as one of possible ways of the balance of electric power in Poland. Particularly, that it will be expected the special ecological conditions in the energy production in Europe. In the present work, was shown, that the nuclear power was discriminated in the analysis of the development of power and fuel system in Poland. The incorrect values of economical parameters concerning of the nuclear power plant was used in the analysing numerical programs. The investment costs, design time and fuel price for nuclear energy was analysed, and shown, that in the proper conditions, the cost of the electric energy produced in the nuclear power plant is compared with the costs of electric energy produced in the conventional power stations. In this work, the proposals of the basic nuclear and radiological safety standards for the nuclear power plant in Poland are shown. (author). 20 refs, 10 figs, 3 tabs

  10. IS INLAND SHIPPING NEEDED IN POLAND?

    2014-06-01

    Full Text Available In Poland, inland shipping plays only a mariginal role in transport needs fulfillment. Inland shipping has a share of mere 0,3% in goods transport modal split. The reason for this is poor and variable technical parameters of inland waterways together with adverse legal regulations. Different situation takes place in Western European countries, in which the development of this mode of transport is viewed as a way of road transport develop-ment restraint. In Poland, the need to move some of the volume from road transport to in-land shipping is specifically observed within marine ports surroundings. Because of their complex nature, the investments in inland shipping infrastructure would also be helpful in solving the current problems of water management. Inland waterways in Poland guaran-tee neither an adequate level of flood protection, nor the water needs fulfillment of do-mestic economy. When it comes to water reserves, Poland is one of the most deficient countries in Europe. Thus there is a need to invest in inland waterways in Poland.

    Mobius syndrome is a rare condition of unclear origin, characterized by a unilateral or bilateral congenital facial weakness with impairment of ocular abduction, which is frequently associated with limb anomalies . Poland described a condition in which there was unilateral absence of pectoralis major muscle and ipsilateral syndactyly. The combination of Poland-Mobius syndrome is rare, with an estimated prevalence 1:500 000. We describe a case of Poland-Mobius syndrome in association with congenital bilateral vocal fold immobility. To our knowldge, this is the first report of such an association between Poland-Mobius syndrome and congenital bilateral vocal fold immobility.

  12. NiO and Fe/Mn in Fo-rich olivines from OIB, MORB, and mantle peridotites

    Olivines from mantle peridotites have a narrow range of NiO (0.36±0.03 [1σ] wt%), but NiO of olivines in basalts suggest NiO in mantle olivines is actually more variable: e.g., Hawaiian phenocrysts (Fo>90) have NiO >0.55%, and olivines from continental flood basalts can have >0.5% NiO. At the other end of the spectrum, some basaltic suites (e.g., Iceland, MORBs) have Fo>90 olivines with NiO >0.2%. Partial melting calculations on peridotites show it is difficult to generate liquids that crystallize Fo>90 olivines with >0.4% NiO without resorting to complex processes. Hypotheses to explain the variability of NiO in mantle-derived olivines include (1) reaction of peridotite with silica-rich melts of eclogite results in decreasing modal abundance of olivine and increasing NiO in olivine [1,2]; (2) magmas with NiO-rich olivines come from sources enriched in NiO due to a core-derived component [3]. [4] proposed that high Fe/Mn of Hawaiian vs. Icelandic and MORB lavas reflect a core-derived component in their sources. Possible core incorporation is poorly constrained but FeO and NiO are expected to increase by such processes, leading to correlations between NiO and Fe/Mn in mantle rocks with significant core-derived components. We present high-precision analyses of Fo-rich olivines from OIBs, MORBs, komatiites, and mantle peridotites, focusing on NiO contents and Fe/Mn ratios. Our goal is to test hypotheses to explain elevated NiO of Fo-rich olivines in basalts. Olivines are Fo85.1-93.4; more were analyzed, but we focused on this range to avoid complications due to decreasing NiO in olivine with crystallization. Errors (1σ) are 0.01 wt% in NiO and 1.5 in Fe/Mn (wt). Our data show several features: (1) NiO contents and Fe/Mn ratios of Fo>88 olivines are positively correlated, with the low end of the trend (NiO ~0.23%, Fe/Mn ~61) defined by MORB and Iceland and the high end of the trend (NiO ~0.55%, Fe/Mn ~80) by Reunion and Hawaii. Between these end points, there is a

    In 2004, Poland has adopted the WHO goal of rubella elimination and congenital rubella syndrome prevention. The main target of the Programme is to stop transmission of the virus in the environment and prevention of congenital rubella in children. In Poland participation in the rubella elimination program requires clinical diagnosis of rubella cases and their confirmation with laboratory tests. Vaccination against rubella was introduced in 1987, initially only in 13 - year-old girls. Since 2003, single jab vaccination against rubella, measles and mumps is used (MMR vaccine for all children: primary vaccination at the age 13-15 months and a booster vaccination at the age of 10). To assess epidemiological situation of rubella in Poland in 2014, including vaccination coverage in Polish population. The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletins “Infectious diseases and poisonings in Poland in 2014” and “Vaccinations in Poland in 2014” (MP. Czarkowski, Warszawa 2014, NIZP-PZH, GIS). In 2014, there was a significant decrease in the number of rubella cases - with registered 5891 cases (in 2013 - 38 548 cases) - and a decline in incidence (from 101.1 per 100 000 to 15.3). The highest incidence, regardless of gender and the environment was observed in the age group 5-6 years (respectively 93.8 and 109.4 per 100 000). Similarly to 2013, rubella incidence of males was higher than the incidence in girls and women (20.0 versus 10.9). In 2014, no cases of congenital rubella syndrome were registered. The proportion of laboratory tests confirming/excluding rubella infection is still very low in Poland. In 2014, only 0.6% of rubella cases were laboratory confirmed.

    Vaccination against mumps from 2003 is mandatory in Poland and given as two dose scheme with MMR vaccine (mumps, measles, and rubella). Earlier this vaccination was only recommended. Despite observed decline in mumps incidence for over a decade which is a result of conducted vaccinations, mumps is still a common childhood disease. To assess epidemiological situation of mumps in Poland in 2013, including vaccination coverage in Polish population, in comparison to previous years. The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletins "Infectious diseases and poisonings in Poland in 2013" and "Vaccinations in Poland in 2013" (Czarkowski MP i in., Warszawa 2013, NIZP-PZH i GIS). Mumps cases were classified according to the criteria of surveillance case definition implemented in the European Union (Commission Decision of 28 April 2008 amending Decision 2002/253/EC). National Immunisation Programme for year 2013 was also used. In total, there were 2 436 mumps cases registered in Poland in 2013. Incidence of mumps was 6.3 per 100,000 and it was lower by 12.5% in comparison with 2012 and lower by 18.2% in comparison with median for the years 2007-2010. The highest incidence rate was observed among children aged 5 years (54.0 per 100,000). Incidence in men (7.5) was higher than in women (5.2). In 2013, 38 people were hospitalized due to mumps. Vaccination coverage of children aged 3 years in Poland in 2013 was 97.5% and it was lower by 0.4% in comparison with year 2012. Systematic execution of mumps vaccination in accordance with the National Immunisation Programme resulted in a significant decrease in the number of registered cases. Due to the high vaccination coverage further decline in the number of cases is expected.

  15. Hepatitis A in Poland in 2014

    Polański, Piotr

    The aim of this article is to assess the epidemiological situation of hepatitis A in Poland in 2014 with the regard to the recent years. The assessment was conducted based on the results of the analysis of data from the bulletins “Infectious diseases and poisonings in Poland in 2014” and “Vaccinations in Poland in 2014”, as well as information from the individual cases questionnaires and reports of epidemiological investigations in outbreaks of hepatitis A, submitted by the sanitary-epidemiological stations to the Department of Epidemiology in NIPH-NIH. In 2014 in Poland there were 76 cases of hepatitis A registered. Incidence per 100 000 inhabitants was 0.20, and in different voivodeships varied from 0.07 (in Dolnosląskie voivodeship) to 0.30 (in Małopolskie voivodeship). The incidence among male and female did not differ (and was 0.20/ 100 000). In 2014 despite the increase in the number of cases (comparing it to the previous year) no significant change in epidemiological situation of hepatitis A was observed. Poland is still regarded as a country of low endemicity of hepatitis A. In routine surveillance system there is no information concerning the professional affiliation of persons being vaccinated, whereas the vaccinations themselves are recommended in the Polish vaccination schedule. Particular attention should be directed towards the vaccinations of persons who take part in berries primal production, product of which Poland is a major exporter of in the EU. In the light of increasing number of international hepatitis A outbreaks (which could be characterized by the prolonged duration, as well as the high possibility of secondary cases appearing- especially in countries of low endemicity) the maintenance of high level routine surveillance in Poland gains importance. The latter could also contribute to the efficiency of epidemiological investigations in multistate outbreaks.

  16. Metasomatic Reaction Zones as Monitors of Trace Element Transfer at the Slab-Mantle Interface: the Case of the Hochwart Peridotite (Ulten Zone, Italy)

    Ultramafic blocks belonging to the Hochwart peridotite outcrop (Ulten Zone, Italian Alps) preserve a series of metasomatic mineral zones generated by infiltration of Si-rich hydrous fluids which occurred at the gneiss- peridotite interface. The age of the high pressure metamorphism for the Hochwart complex has been constrained at 330 Ma (Tumiati et al., 2003, EPSL, 210, 509-526). The country rocks are stromatic gneisses consisting mainly of quartz, K-feldspar, garnet, kyanite, biotite and muscovite. The ultramafic body consists of strongly serpentinized metaperidotites which are exposed as a hectometre-size lens along a steep gully, associated to monomineralic zones that developed at the contact between the peridotite body and the garnet gneiss country rocks. The composition of the metasomatic zones has been investigated in detail and records an order of metasomatic zoning formed by phlogopite-rich to tremolite-anthophyllite-rich rocks going from the host gneiss towards the peridotite. In some cases, the ultramafics fade into the gneisses developing serpentine and talc which has replaced, presumably at lower temperatures, the serpentine matrix and occurs in association with chlorite. Phlogopite aggregates (phlogopitite) with accessory minerals (quartz + zircon + apatite) and metabasic pods (phlogopite and hornblende) also occur. Black tourmaline (schorl-dravite solid solution) has been found for the first time in the contact near the phlogopite zone, suggesting an external addition of elements (boron and fluorine) to the system at high temperature. The formation of the metasomatic zones composed exclusively of hydrous phases must have involved extensive H2O-metasomatism as already documented for the Ulten peridotites. The source for these fluids can be a system of trondhjemitic-pegmatitic dikes cutting the peridotite that would have channelled aqueous fluids into the ultramafic rocks. Whole-rock geochemistry and trace element (LA ICP-MS) composition of hydrous

    Spinel pyroxene-clusters, which are intergrowths of spinel, orthopyroxene and clinopyroxene in mantle xenoliths, have been investigated through the use of micro-CT (μ-CT) in this study. Samples have been studied from two different tectonic settings: (1) the northern Massif Central, France, an uplifted and rifted plateau on continental lithosphere and (2) Lanzarote in the Canary Islands, an intraplate volcanic island on old oceanic lithosphere. μ-CT analysis of samples from both locations has revealed a range of spinel textures from small Lanzarote are regions that have experienced significant lithospheric thinning. This process provides a mechanism where the sub-solidus reaction of olivine + garnet = orthopyroxene + clinopyroxene + spinel is satisfied by providing a pathway from garnet peridotite to spinel peridotite. We predict that such textures would only occur in the mantle beneath regions that show evidence of thinning of the lithospheric mantle. Metasomatic reactions are seen around spinel-pyroxene clusters in some Lanzarote xenoliths, so metasomatism post-dated cluster formation.

  18. Nuclear Physics in Poland

    2004-01-01

    Full text: This will be a short presentation of low and high energy nuclear physics in Poland, its history, essential results, and the present status. Nuclear physics in Poland has a tradition of hundred years. Research started just after the discovery of radium and polonium by Polish-born Maria Sklodowska-Curie and her husband Pierre Curie. Maria Sklodowska-Curie employed numerous Polish assistants in her Paris laboratory and supported radioactivity studies in Warsaw, her birth place, then under the occupation of tsarist Russia. In the first decades of the XXth century Poland was one of the leading countries in radioactivity studies. In the late 1930-ies a cyclotron was constructed in Warsaw and an ambitious 'Star of Poland' project was launched to study the cosmic rays. Unfortunately, the Second World War stopped all scientific activity in Poland. A large fraction of Polish physicists perished in the period 1939-1945. After the World War nuclear physics of low and high energy was rebuilt in Warsaw and Krakow. Already in 1952 Marian Danysz and Jerzy Pniewski discovered the first hypernucleus. This important discovery was essential to understand the properties of numerous new particles found in cosmic rays. Polish physicists entered intensive collaboration with both CERN and Dubna and took part also in research at other centers in Europe (DESY, GSI, GANIL, Julich, SACLAY) and the United States (Fermilab). At present the research is concentrated in Warsaw and Krakow (the two largest centers), and smaller teams, mostly theorists, are also in Bialystok, Katowice, Kielce, Lublin, Lodz and Wroclaw. Several years ago a heavy ion cyclotron was built in Warsaw. Among the important discoveries made by Polish nuclear physicists one may mention the theoretical works on superheavy elements and the recent discovery of the two-proton radioactivity

    We present a detailed geochemical investigation on the Hf, Nd and Sr isotope compositions and trace and major element contents of clinopyroxene mineral separates from spinel lherzolite xenoliths from the island of Oahu, Hawaii. These peridotites are believed to represent the depleted oceanic lithosphere beneath Oahu, which is a residue of a MORB-related melting event some 80-100 Ma ago at a mid-ocean ridge. Clinopyroxenes from peridotites from the Salt Lake Crater (SLC) show a large range of Hf isotopic compositions, from ɛHf=12.2 (similar to the Honolulu volcanics series) to extremely radiogenic, ɛHf=65, at nearly constant 143Nd/ 144Nd ratios ( ɛNd=7-8). None of these samples show any isotopic evidence for interaction with Koolau-type melts. A single xenolith from the Pali vent is the only sample with Hf and Nd isotopic compositions that falls within the MORB field. The Hf isotopes correlate positively with the degree of depletion in the clinopyroxene (e.g. increasing Mg#, Cr#, decreasing Ti and heavy REE contents), but also with increasing Zr and Hf depletions relative to the adjacent REE in a compatibility diagram. The Lu/Hf isotope systematics of the SLC clinopyroxenes define apparent ages of 500 Ma or older and these compositions cannot be explained by mixing between any type of Hawaiian melts and the depleted Pacific lithosphere. Metasomatism of an ancient (e.g. 1 Ga or older) depleted peridotite protolith can, in principle, explain these apparent ages and the Nd-Hf isotope decoupling, but requires that the most depleted samples were subject to the least amount of metasomatism. Alternatively, the combined isotope, trace and major element compositions of these clinopyroxenes are best described by metasomatism of the 80-100 Ma depleted oceanic lithosphere by melts products of extensive mantle-melt interaction between Honolulu Volcanics-type melts and the depleted lithosphere.

  20. The Force of Crystallization and Fracture Propagation during In-Situ Carbonation of Peridotite

    Full Text Available Subsurface mineralization of CO2 by injection into (hydro-fractured peridotites has been proposed as a carbon sequestration method. It is envisaged that the expansion in solid volume associated with the mineralization reaction leads to a build-up of stress, resulting in the opening of further fractures. We performed CO2-mineralization experiments on simulated fractures in peridotite materials under confined, hydrothermal conditions, to directly measure the induced stresses. Only one of these experiments resulted in the development of a stress, which was less than 5% of the theoretical maximum. We also performed one method control test in which we measured stress development during the hydration of MgO. Based on microstructural observations, as well as XRD and TGA measurements, we infer that, due to pore clogging and grain boundary healing at growing mineral interfaces, the transport of CO2, water and solutes into these sites inhibited reaction-related stress development. When grain boundary healing was impeded by the precipitation of silica, a small stress did develop. This implies that when applied to in-situ CO2-storage, the mineralization reaction will be limited by transport through clogged fractures, and proceed at a rate that is likely too slow for the process to accommodate the volumes of CO2 expected for sequestration.

    According to the Directive 2009/28/EC of the European Parliament and of the European Council on the promotion of the use of energy from renewable sources the target for the share of energy from renewable sources in gross final energy consumption in the year 2020 for Poland is 15%. Poland promotes renewable electricity through a quota system, tax relief and subsidies, as well as loans. There are three subsidy models and a loan scheme, which support heat generated from renewable energy sources. In dimension to transport renewable energy is promoted primarily by bio-fuels. The Republic of Poland established two programmes for renewable energy plants: a training programme, which is dedicated to installers in RES sector and certification system pertaining solar thermal installations. This report monitors the policy changes after the release of the 2013 Progress Report for Poland and was regularly updated (updated until December 2015)

    The Betic Cordillera and the Moroccan Rif together form one of the smallest and tightest orogenic arcs on Earth and almost completely close the Mediterranean to the west. For the explanation of the geodynamic evolution of the mountain belt, palaeomagnetic data that generally found clockwise block rotations in the Iberian and anticlockwise rotations in the Moroccan part of the mountain belt, have played a key role in recent works. This palaeomagnetic study has found new constraints on the rotations and timing of the peridotitic bodies outcropping in the key position at the westernmost margin of the mountain belt, in Ceuta and Beni Bousera (Rif, northern Africa). Detailed thermal demagnetization of 115 individually oriented samples from 14 sites was combined with rock magnetic and scanning electron microscopic experiments to analyze the magnetic mineralogy responsible for the remanences and the mechanisms and relative times of their acquisition. In Ceuta, up to three magnetic components, and in Beni Bousera, up to two magnetic components have been found, that are all to be interpreted as chemical remanent magnetizations (CRM). The data suggests the following succession of geodynamic events affecting the peridotites until recent times: (1) after their exhumation and subsequent cooling about 20 Ma ago, they recorded a characteristic remanent magnetization of both normal and reversed polarities, carried by (pseudo-)single-domain magnetite grains; (2) after their dismembering, the Ceuta peridotites were tilted southward by 22-34° about a horizontal or tilted axis (up to plunge 50°) with an azimuth of 72-145° and the Beni Bousera peridotites were rotated anticlockwise by 72.3 ± 12.1° about a vertical axis and (3) both recorded another magnetic signal of normal polarity only, carried by multi-domain magnetite grains; and finally (4) the Ceuta peridotites rotated anticlockwise by 19.7 ± 5.9° about a vertical axis. This study provides the first palaeomagnetic data for

    Full Text Available Over the last quarter of the century relations between Russia and Poland are balancing between trying to understand the burden of mutual guilt and a desire to construct non-emotional pragmatic relations. Sources of tension vary. In particular, it is the desire of Poland to position itself as a valued player in NATO and the EU and the role distance between the two countries in IR system, which does not allow Russia to maintain an equal political dialogue with Poland. In fact, Poland is not afraid of a direct threat from Russia, but the worst scenario is the one in which Russia without changing the content of its imperial policy can be accepted as a full partner in the international community. The evolution of Russian statehood and national specifics of democracy is largely determined the assessment of the prospects of Russian politics in Poland. The mistake of Polish diplomacy last years was that it took no direct efforts to improve relations with Russia, but only tried to impose the dialogue on Russian authorities. Diplomatic methods were designed to hurt Russian interests and to create a topic for discussion. In response, after 2006 Russia chose the tactic of ignoring Poland. But, ignoring Polish authorities, Russian politicians acted similarly with other political forces. In Poland among influential political forces, there was and there is still no loyalty to Russia. For Russian interests it is no matter who are or will be in power in Poland. However as a rule, it is an important factor that foreign policy decisions are de facto within the competences of the President and the government, as well as experiencing a significant influence of the parliamentary forces. Recent trends show no tangible innovations in bilateral programme. But innovations appear in multilateral and conflict enough issues, such as deployment of US missile defense system in Poland or Polish supervision of "Eastern Partnership" programme.

    The purpose of the study was evaluation of epidemiological situation of salmonellosis in Poland in 2012 compared to the previous years. The main source of data for this study are statistical overviews contained in the annual bulletins "Infectious Diseases in Poland in 2012" (NIZP-PZH, GIS, Warsaw 2013), reports from investigations obtained from the sanitary epidemiological stations. Information on deaths due to infectious and parasitic diseases registered in Poland in 2012 and earlier years is based on the data from the Department for Demographic Research of Central Statistical Office. For the purpose of surveillance cases were classified according to the case definition. In Poland in 2012, it was reported a total of 8 444 cases of zoonotic salmonellosis including 8 267 cases of intestinal salmonellosis and 177 of extraintestinal one. The incidence was 21.9/100 000. The criteria for a confirmed case met more than 94% of cases. The number of reported cases was lower than in 2011, reflecting the continued downward trend in the number of cases of salmonellosis in Poland. A very high percentage (69.4%) hospitalizations of people infected with zoonotic Salmonella remains. In outbreaks proportion of hospitalizations accounted for one third of the cases. Predominated children under the age of 5 years. Seven people died of salmonellosis. In 2012, it was reported 181 outbreaks caused by Salmonella in which 1 511 people still. They were mostly small family outbreaks. The most common etiological agent of salmonellosis in Poland is S. enteritidis, but slightly increases the percentage cases, for which no serologic type was determined. In 2012 it stood at 14%. This proportion was highest in the Pomorskie province and amounted to 58%. Keeping up for more than 10 years in the percentage of salmonellosis hospitalization rate at 70%, indicates underreporting of the disease in the country and mostly detection of the cases requiring hospital treatment.

    Cooling rates of ocean floor mantle rocks from mid-ocean ridges can potentially provide important information about ridge dynamics, emplacement mechanisms and mantle uplift. There are a growing number of geospeedometric methods to retrieve such cooling rates in various settings. However, few exist for typical four- phase mantle peridotites and they only cover temperatures below 800° C. The down-temperature lithophile trace element exchange between clinopyroxene (cpx) and orthopyroxene (opx) can provide such a high- temperature spinel peridotite geospeedometer. Orthopyroxenes studied by SIMS from two fresh Gakkel Ridge peridotites are zoned in all trace elements while clinopyroxenes are homogeneous. This allows the calculation of equilibrium temperatures [1]. Several profiles in opx cover a range of 1250° C (opx core) to 800° C (opx rim) and are in agreement with straightforward diffusion and closure temperature models. The systematics of REE diffusion in opx deviate from the results of a recent experimental study [2]. The data allow us to estimate diffusion systematics of 16 elements (REE and TE) and their cation distributions in orthopyroxene. The data set is internally coherent as all elements were subjected to the same extrinsic parameters. 1. Decreasing ionic radius increases REE diffusion in opx (as it does in cpx). 2. M2-site diffusion is controlled more by ionic radius than by cationic charge. 3. M1-site diffusion is controlled by both ionic radius and cationic charge. 4. M1-site diffusion is generally slower than M2-site diffusion for isovalent cations, most likely because of higher M1- site energies compared to M2-site. The advantages of this geospeedometer should be its relatively good precision, use of standard analytical methods and its coverage of the important range between solidus temperatures and 800° C. In combination with other geospeedometers it will be possible to retrieve the continuous cooling history of a mantle rock from its solidus down

    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.

  10. Lithosphere destabilization by melt percolation during pre-oceanic rifting: Evidence from Alpine-Apennine ophiolitic peridotites

    2017-04-01

    Orogenic peridotites from Alpine-Apennine ophiolite Massifs (Lanzo, Voltri, External and Internal Ligurides, - NW Italy, and Mt. Maggiore - Corsica) derive from the mantle lithosphere of the Ligurian Tethys. Field/structural and petrologic/geochemical studies provide constraints on the evolution of the lithospheric mantle during pre-oceanic passive rifting of the late Jurassic Ligurian Tethys ocean. Continental rifting by far-field tectonic forces induced extension of the lithosphere by means of km-scale extensional shear zones that developed before infiltration of melts from the asthenosphere (Piccardo and Vissers, 2007). After significant thinning of the lithosphere, the passively upwelling asthenosphere underwent spinel-facies decompression melting along the axial zone of the extensional system. Silica-undersaturated melt fractions percolated through the lithospheric mantle via diffuse/focused porous flow and interacted with the host peridotite through pyroxenes-dissolving/olivine-precipitating melt/rock reactions. Pyroxene dissolution and olivine precipitation modified the composition of the primary silica-undersaturated melts into derivative silica-saturated melts, while the host lithospheric spinel lherzolites were transformed into pyroxene-depleted/olivine-enriched reactive spinel harzburgites and dunites. The derivative liquids interacted through olivine-dissolving/orthopyroxene+plagioclase-crystallizing reactions with the host peridotites that were impregnated and refertilized (Piccardo et al., 2015). The saturated melts stagnated and crystallized in the shallow mantle lithosphere (as testified by diffuse interstitial crystallization of euhedral orthopyroxene and anhedral plagioclase) and locally ponded, forming orthopyroxene-rich/olivine-free gabbro-norite pods (Piccardo and Guarnieri, 2011). Reactive and impregnated peridotites are characterized by high equilibration temperatures (up to 1250 °C) even at low pressure, plagioclase-peridotite facies

  14. Further Sr and Nd isotopic results from peridotites of the Ronda Ultramafic Complex

    International Nuclear Information System (INIS)

    Reisberg, L.; Zindler, A.

    1989-01-01

    Clinopyroxenes derived from peridotites of the spinel and garnet facies of the Ronda Ultramafic Complex yield Sr and Nd isotopic ratios which extend the range of compositions found in the massif to values as depleted as 0.70205 for Sr and 0.51363 for Nd. Large-amplitude, short-wavelength isotopic variations are found to be uniquitous throughout the massif. In the garnet facies, some of these variations are shown to be produced by the tectonic disaggregation of mafic layers in an isotopically depleted peridotite matrix. Ages obtained from garnet-clinopyroxene Sm-Nd isochrons (about 22 m.y.) agree with previous determinations of the time of crustal emplacement. In the plagioclase facies, where the Sr and Nd isotopic compositions have been very strongly affected by recent cryptic metasomatism, detailed study of one sample reveals that intermineral Nd isotopic equilibrium exists between clinopyroxene, orthopyroxene, and plagioclase. This indicates that the metasomatism occurred at high temperatures, and thus probably within the mantle. A rough correlation between 143 Nd/ 144 Nd and 147 Sm/ 144 N, with an apparent 'age' of 1.3 b.y. and an initial ε Nd (0) value of +6.0, is observed among clinopyroxenes derived from river sediments from throughout the massif. This age is interpreted as the time that the massif left the convecting mantle and became incorporated into the sub-continental lithosphere. (orig.)

    The potential for innovativeness is difficult to measure, though many have attempted to do so. In order to look at Poland's innovation potential, its current position and its opportunity to grow, compared with developing and developed countries, this study analysed the patent statistics of the Polish and European Patent Offices. Poland has been a member of the European Union for over a decade now. Therefore, we took into consideration the statistics for patent applications and grants for the last decade, up to the first quarter of 2016. The questions we wanted to answer concerned not only the technology fields that Poland patented its inventions in, but also the types of patent grantees and applicants. In order to determine why Poland is still considered to be only a moderate innovator by the Innovation Union Scoreboard, we also gathered information on Polish inventors abroad in 2015 and the first quarter of 2016, to see their number, technology fields, and types of patent grantees. Finally, we attempted to identify the main barriers that seem to inhibit Polish technology and innovation growth, despite significantly growing R&D intensities (up from 0.56 GDP and EUR 1,139 M in 2004 to 0.94 GDP and EUR 3,864 M in 2014).

  18. Post-accession economic development of Poland

    2011-12-01

    Full Text Available The aim of this paper is to analyse the economic performance of Poland in the post-accession period. Poland joined the EU in 2004, after a long and difficult economic transition. The whole post-accession period could be divided into two sub-periods: the pre-crisis period of 2004-07, and the turbulent period of 2008-11. During the pre-crisis period, Poland recorded a fast growth, with a built-up of macroeconomic disequilibria. During the turbulent period, the economy was dealing successfully with the global financial crisis. The growth slowed down and the disequilibria were reduced. The paper discusses the growth patterns in the both sub-periods and tries to explain the factors that contributed to the good economic performance during the financial crisis. The astonishingly good economic growth results cannot be attributed to a single factor, but to a combination of many factors contributing at the same time. However, Poland has many valuable assets that may help in dealing with the further economic turbulences.

  20. Serpentinization of mantle-derived peridotites at mid-ocean ridges: Mesh texture development in the context of tectonic exhumation

    Science.gov (United States)

    Rouméjon, Stéphane; Cannat, Mathilde

    2014-06-01

    At slow spreading ridges, axial detachment faults exhume mantle-derived peridotites and hydrothermal alteration causes serpentinization in a domain extending more than 1 km next to the fault. At the microscopic scale, serpentinization progresses from a microfracture network toward the center of olivine relicts and forms a mesh texture. We present a petrographic study (SEM, EBSD, and Raman) of the serpentine mesh texture in a set of 278 abyssal serpentinized peridotites from the Mid-Atlantic and Southwest Indian Ridges. We show that serpentinization initiated along two intersecting sets of microfractures that have consistent orientations at the sample scale, and in at least one studied location, at the 100 m scale. We propose that these microfractures formed in fresh peridotites due to combined thermal and tectonic stresses and subsequently served as channels for serpentinizing fluids. Additional reaction-induced cracks developed for serpentinization extents <20%. The resulting microfracture network has a typical spacing of ˜60 µm but most serpentinization occurs next to a subset of these microfractures that define mesh cells 100-400 µm in size. Apparent mesh rim thickness is on average 33 ± 19 µm corresponding to serpentinization extents of 70-80%. Published laboratory experiments suggest that mesh rims formation could be completed in a few years (i.e., quasi instantaneous at the plate tectonic timescale). The depth and extent of the serpentinization domain in the detachment fault's footwall are probably variable in time and space and as a result we expect that the serpentine mesh texture at slow spreading ridges forms at variable rates with a spatially heterogeneous distribution.

  3. Water content within the oceanic upper mantle of the Southwest Indian Ridge: a FTIR analysis of orthopyroxenes of abyssal peridotites

    Water can be present in the oceanic upper mantle as structural OH in nominally anhydrous minerals. Such water has marked effects on manlte melting and rheology properties. However, the water content of MORB source is mainly inferred from MORB glass data that the water budget of oceanic upper mantle is poorly constrained. Here we present water analysis of peridotites from different sites on the Southwest Indian Ridge. The mineral assemblages of these peridotites are olivine, orthopyroxene, clinopyroxene and spinel. As the peridotites have been serpentinized to different degrees, only water contents in orthopyroxnene can be better determined by FTIR spectrometry. The IR absorption bands of all measured orthopyroxenes can be devided into four different groups: (1)3562-3596 cm-1, (2)3515-3520 cm-1, (3)3415-3420 cm-1, (4)3200-3210 cm-1. The positions of these absorption bands are in good agreement with perivious reports. Hydrogen profile measurements performed on larger opx grains in each suite of samples show no obvious variations between core and rims regions, indicating that diffusion of H in orthopyroxene is insignificant. Preliminary measured water contents of orthopyroxene differ by up to one order of magnitude. Opx water contents (80-220 ppm) of most samples are within the range of those found in mantle xenoliths of contentinal settings [1]. Opx water contents of one sample (VM-21V-S9-D5-2: 38-64 ppm) are similar to those from Gakkel Ridge abyssal peridotites (25-60 ppm) [2] but higher than those from Mid-Atlantic Ridge ODP-Leg 209(~15 ppm) [3]. Two other samples show high water concentrations (VM-19ΙΙΙ-S3-TVG2-4: 260-275 ppm, Wb-18-b: 190-265 ppm) which compare well with those from Mid-Atlantic Ridge ODP-Leg 153(160-270 ppm) [4]. Most opx water contents decrease with increasing depletion degree (spl Cr#) consistent with an incompatible behavior of water during partial melting. Recalculated bulk water contents (27-117 ppm) of these peridotites overlap

    To better understand processes above subducted oceanic slabs, we have undertaken experiments with juxtaposed sediment and peridotite layers at pressures of 7.5 and 10.5 GPa at a controlled temperature gradient from ∼100 to ∼500 °C per a sample length of ∼3 mm. The sediment starting material contains H2O (6.9 wt%) and CO2 (5.9 wt%) and has a major-element composition similar to GLOSS (Plank and Langmuir, 1998) doped with trace elements at 10-100 ppm levels. Several experiments were conducted with ∼0.5 wt% Cl or F. The peridotite layer is composed of natural olivine (66 wt%), orthopyroxene (27 wt%) and garnet (7 wt%) mixed with ∼15 wt% graphite. Several experimental configurations were investigated, but the "basic" setup has the sediment layer at the bottom in the cold zone (400-1200 °C) overlain by peridotite at 900-1500 °C. The temperature distribution was determined by two thermocouples and orthopyroxene-garnet thermometry. Features common to many experiments are (1) the development of multiple layers of various lithologies and a pool of hydrous silicate or carbonate-silicate melt in the hottest part of the capsule; (2) replacement of olivine by orthopyroxene in the metaperidotite; (3) preservation and growth of garnet and local development of magnesite in the metaperidotite layer; (4) enrichment in garnet within the metasediment layer at the contact with the metaperidotite; (5) formation of a clinopyroxene-garnet assemblage at the bottom (the coldest part); (6) presence of K-bearing phases (phlogopite or phengite) and carbonates in the metasediment layer only at temperatures Ca are largely retained in the coldest part of the metasediment layer in clinopyroxene, Ca-rich garnet and aragonite. The melt is a product of interaction between partial melt or fluid from the sediment and peridotite. It has a silico-carbonatite composition with variable SiO2, MgO, FeO and CaO contents and low Al2O3. The addition of Cl has almost no effect on element

  5. The Effect of CO2 on Partial Reactive Crystallization of MORB-Eclogite-derived Basaltic Andesite in Peridotite and Generation of Silica-Undersaturated Basalts

    Recycled oceanic crust (MORB-eclogite) is considered to be the dominant heterogeneity in Earth's mantle. Because MORB-eclogite is more fusible than peridotite, siliceous partial melt derived from it must react with peridotite while the latter is still in the subsolidus state. Thus, studying such reactive process is important in understanding melting dynamics of the Earth's mantle. Reaction of MORB-eclogite-derived andesitic partial melt with peridotite can produce alkalic melts by partial reactive crystallization but these melts are not as silica-undersaturated as many natural basanites, nephelinites or melititites [1]. In this study, we constrain how dissolved CO2 in a siliceous MORB-eclogite-derived partial melt affects the reaction phase equilibria involving peridotite and can produce nephelinitic melts. Here we compare experiments on CO2-free [1] and 2.6 wt.% CO2 bearing andesitic melt+lherzolite mixtures conducted at 1375 °C and 3 GPa with added melt fraction of 8-50 wt.%. In both CO2-free and CO2-bearing experiments, melt and olivine are consumed and opx and garnet are produced, with the extent of modal change for a given melt-rock ratio being greater for the CO2-bearing experiments. While the residue evolves to a garnet websterite by adding 40% of CO2-bearing melt, the residue becomes olivine-free by adding 50% of the CO2-free melt. Opx mode increases from 12 to ~55 wt.% for 0 to 40% melt addition in CO2-bearing system and 12 to ~43 wt.% for 0 to 50% melt addition in CO2-free system. Garnet mode, for a similar range of melt-rock ratio, increases from ~10 to ~15 wt.% for CO2 bearing system and to ~11 wt.% for CO2-free system. Reacted melts from 25-33% of CO2-bearing melt-added runs contain ~39 wt.% SiO2 , ~11-13 wt.% TiO2, ~9 wt.% Al2O3, ~11 wt.% FeO*, 16 wt.% MgO, 10-11 wt.% CaO, and 3 wt.% Na2O whereas experiments with a similar melt-rock ratio in a CO2-free system yield melts with 44-45 wt.% SiO2, 6-7 wt.% TiO2, 13-14 wt.% Al2O3, 10-11 wt.% FeO*, 12-13 wt

  6. Air protection strategy in Poland

    Energy Technology Data Exchange (ETDEWEB)

    1995-12-31

    Air quality is one of the basic factors determining the environmental quality and influencing the life conditions of people. There is a shortage of proper quality air in many regions of Poland. In consequence, and due to unhindered transport, air pollution is the direct cause of losses in the national economy (reduction of crops, losses in forestry, corrosion of buildings and constructions, worsening of people`s health). Poland is believed to be one of the most contaminated European countries. The reason for this, primarily, is the pollution concomitant with energy-generating fuel combustion; in our case it means the use of solid fuels: hard coal and lignite. This monocultural economy of energy generation is accompanied by low efficiency of energy use (high rates of energy loss from buildings, heat transmission pipelines, energy-consuming industrial processes). This inefficiency results in the unnecessary production of energy and pollution. Among other reasons, this results from the fact that in the past Poland did not sign any international agreements concerning the reduction of the emission of pollution. The activities aimes at air protection in Poland are conducted based on the Environmental Formation and Protection Act in effect since 1980 (with many further amendments) and the The Ecological Policy of the state (1991). The goals of the Polish air pollution reduction program for the period 1994-2000 are presented.

  8. Theoretical calculation of shakeup intensities using Xa--SW wave functions

    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

    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.

    2009-11-01

    In order to address diamond formation and origin in the lithospheric mantle underlying the Central Slave Craton, we report N- and C-stable isotopic compositions and N-contents and aggregation states for 85 diamonds of known paragenesis (73 peridotitic, 8 eclogitic and 4 from lower mantle) from the Panda kimberlite (Ekati Mine, Lac de Gras Area, Canada). For 12 peridotitic and two eclogitic sulfide inclusion-bearing diamonds from this sample set, we also report multiple-sulfur isotope ratios. The 73 peridotitic diamonds have a mean δ13C-value of - 5.2‰ and range from - 6.9 to - 3.0‰, with one extreme value at - 14.1‰. The associated δ15N-values range from - 17.0 to + 8.5‰ with a mean value of - 4.0‰. N-contents range from 0 to 1280 ppm. The 8 eclogitic diamonds have δ13C-values ranging from - 11.2 to - 4.4‰ with one extreme value at - 19.4‰. Their δ15N ranges from - 2.1 to + 7.9‰ and N-contents fall between 0 and 3452 ppm. Four diamonds with an inferred lower mantle origin are all Type II (i.e. nitrogen-free) and have a narrow range of δ13C values, between - 4.5 and - 3.5‰. The δ34S of the 14 analyzed peridotitic and eclogitic sulfide inclusions ranges from - 3.5 to +5.7‰. None of them provide evidence for anomalous δ33S-values; observed variations in δ33S are from +0.19 to - 0.33‰, i.e. within the 2 sigma uncertainties of mantle sulfur ( δ33S = 0‰). At Panda, the N contents and the δ13C of sulfide-bearing peridotitic diamonds show narrower ranges than silicate-bearing peridotitic diamonds. This evidence supports the earlier suggestion established from eclogitic diamonds from the Kaapvaal that sulfide-(±silicate) bearing diamonds sample a more restricted portion of sublithospheric mantle than silicate-(no sulfide) bearing diamonds. Our findings at Panda suggest that sulfide-bearing diamonds should be considered as a specific diamond population on a global-scale. Based on our study of δ34S, Δ 33S, δ15N and δ13C, we find no

    High-quality seismic reflection data recently acquired in SE Poland provide new insights into the structure of the contact between the East European Craton (EEC) and the younger terranes to the SW. Our study focuses on two regional tectonic units: (1) the Radom-Kraśnik Block (RKB), a NW-SE elongate structural high where early Palaeozoic to Devonian strata subcrop beneath the Permo-Mesozoic cover, and (2) the Lublin Basin (LB), a major Palaeozoic sedimentary basin developed above the SW slope of the EEC and filled by the Neoproterozoic - Carboniferous strata. The RKB separates the LB from the Małopolska Massif (MM) and Łysogóry Unit (LU) that are usually considered early Palaeozoic terranes docked to the SW EEC margin. The seismic data show a continuous top-EEC basement that descends from ~2 km in the NE to ~20 km under the SW part of the RKB. The RKB and LB represent a NE-vergent thin-skinned system thrust toward the EEC with the thin-skinned fabric oriented oblique to the slope of the EEC basement. The RKB is a thrust stack that imbricates a 10-12 km thick pile of ?Neoproterozoic to Devonian sediments. A leading edge of the RKB is a triangle zone related to the jump of the basal detachment from a basement-cover interface to Silurian shales. The passive roof of this triangle zone involves Carboniferous strata. This defines the age of thrusting as Variscan. A minor amount of slip that has been conveyed to the Lublin Basin has been accommodated by a gentle deformation of the post-Silurian series. The thin-skinned deformation front is given by the Kock Fault Zone (KFZ) that is a frontal thrust forced to emerge above a step in the Precambrian basement. The KFZ could be partly regarded as an analogue to MUSHWAD structures described in the Appalachian foreland fold-and-thrust belt. It also could be a triangle zone like those in the Appalachian Plateau, but is more similar to the type triangle zone in the Canadian Rockies Foothills. Reinterpretation of published

    The purpose of the study was to evaluate the epidemiologic situation of salmonellosis in Poland in 2013 compared to previous years. The main source of data for this study are statistical overviews included in annual bulletin "Infectious Diseases in Poland in 2013", information from sanitary station laboratories as well as forms of outbreak investigations obtained from the sanitary stations. Information on deaths due to infectious and parasitic diseases registered in Poland in 2013 and earlier years is based on the data of the Department for Demographic Research of Central Statistical Office. For the purpose of surveillance cases were qualified according to the current definition. In Poland in 2013, a total of 7 578 cases of zoonotic salmonellosis were reported including 7 407 cases of intestinal salmonellosis and 171 of parenteral one. The incidence was 19,7/100 000. The criteria for a confirmed case were met by more than 96% of cases. The number of reported cases was lower than in previous year, reflecting the continued downward trend in the number of cases of salmonellosis in Poland. A very high percentage (more than 72%) of hospitalizations of people infected with zoonotic Salmonella continues. In the outbreaks the proportion of hospitalizations accounted only for 35% of all cases. Predominantly children below 5 years of age suffer from the illness. Salmonellosis was an indicated cause of death only in 10 of the cases. In 2013 179 outbreaks were reported, in which Salmonella was found to be the etiological agent. Majority of them were small household outbreaks and they cumulated for a total number of cases of 1 218. The most common species of Salmonella responsible for infection in Poland is S. Enteritidis. For many years, up to date a slight increase is observed in reported cases of the disease, but without known serotype of Salmonella. In 2013 it was 16% and (as in previous year) it was the highest in pomorskie voivodeship (58%). High percentage of

  17. The semi-brittle to ductile transition in peridotite on oceanic faults: mechanisms and P-T condition

    Experimental and geological-petrological studies suggest that the transition from brittle faulting to ductile flow of olivine, i.e. from seismic to aseismic behavior of mantle rocks (peridotites), occurs close to 600°C. However, recent seismological studies on oceanic transform faults (TFs) and ridges have documented earthquakes to temperatures (T) up to 700-800°C. In this study, we carried out a petrological, microstructural and geochemical analysis of natural samples of peridotites dredged at 3 different oceanic TFs of the Southwest Indian Ridge: Shaka, Prince Edward and Atlantis II. We selected samples displaying variable amounts of ductile deformation (from porphyroclastic tectonites to ultramylonites) prior to serpentinization in order to characterize their relatively high-T mechanical behavior. We find that the most deformed samples record cycles of ductile and brittle deformation. Peridotite ductile flow is characterized by drastic grain size reduction and the development of (ultra)mylonitic shear zones. In these zones, a switch in olivine deformation mechanism from dislocation creep to grain-size sensitive creep is associated with dissolution/precipitation processes. Brittle deformation of these samples is evidenced by the presence of (at least centimetric) transgranular and intragranular fractures that fragment coarser grained minerals. Both kinds of fractures are filled with the same phase assemblage as in the ultramylonitic bands: olivine + amphibole ± orthopyroxene ± Al-phase (plagioclase and/or spinel) ± sulfides. The presence of amphibole indicates that this semi-brittle deformation was assisted by hydrous fluids and its composition (e.g. high concentration of chlorine) suggests that the fluids have most likely a hydrothermal origin. We interpret these fractures to have formed under fluid-assisted conditions, recording paleo-seismic activity that alternated with periods of relatively slow interseismic ductile flow.

    The Polish authorities are doing everything in their power to block Nord Stream 2, the Russian natural gas pipeline project that will double (by 2019) Nord Stream 1 through the Baltic Sea. Gazprom's Nord Stream 2 (in which European companies such as Engie (France), Uniper and Wintershall (Germany), OMV (Austria) and Shell are involved) will poses a risk, according to Poland, to the gas supply of central European countries (and notably Ukraine). Poland also intends to stop all its gas imports from Russia after 2022 (end of the Yamal contract): the country is therefore developing its capacity to increase its own natural gas production and has just inaugurated a liquefied natural gas terminal on the Baltic Sea. A gas pipeline is also in project, that will link Norway to Poland. For power generation, the nuclear energy option is also studied

    The sustainable development principle was introduced into the legal system of Poland when the Constitution of the Polish Republic was adopted in 1997. Paradoxically, in Poland - one of the few countries in the world which have introduced the concept of sustainable development at the level of the Constitution, it is difficult to find a reference to it in the political debate. The national sustainable development strategy Poland 2025 has met no response among society and today it seems to be hardly remembered by anybody. An average citizen does not know the concept of sustainable development, or has a vague notion of it, often identifying it exclusively with environmental protection. Solving social problems (the labour market, education, health protection, equality of the sexes, etc.) is not associated with sustainable development whatsoever, and neither is engagement into achieving these development targets on the global scale

  20. [Migrant vaccinations in Poland].

    After the European Union accession in 2004, Poland has been perceived by foreigners as an attractive destination of their migration, and also as a popular transit country for people going further to the Western Europe countries. The Nofer Institute of Occupational Medicine is involved in the implementation of the international project PROMOVAX (Promote Vaccinations among Migrant Populations in Europe). The objective of the project is to promote immunizations among migrant populations in Europe. This article presents the up-to-date legal regulations that are effective in Poland, taking into account their relevance to the issue of vaccinations in migrant population. The analysis of the Polish legislation concerning this problem shows that there are no specific regulations addressed to migrant population staying in our country. This issue seems to be popular in the European Union, where immunization of migrants is given high priority. From the point of view of health care professionals it is important to be aware of the fact that EU open borders favor the increased flow of people between countries. The scale of migration from outside the EU to its member states also contributes to the increase in potential contacts between health care workers and migrants working in Poland.

  1. Illegality of international population movements in Poland.

    Until the beginning of the 1990s Poland did not receive foreign migrants. Thereafter, the situation changed dramatically. A large part of the inflow proved to be illegal migrants, many of whom were in transit to Western Europe. Although these movements gradually declined in the second half of the decade, some became increasingly identified with relatively sophisticated smuggling of people. Foreigners smuggled from the South to the West, together with the international criminal networks assisting them, became typical of the migratory movements of people in Central and Eastern Europe during the 1990s. This article seeks to describe illegal migration from the perspective of Poland, a country often perceived as a major transit area in the smuggling of persons to Western Europe. The conclusions draw on the findings of several surveys recently carried out in Poland. Basic concepts related to illegal migration are defined and juxtaposed, and various myths and stereotypes concerning it that most often stem from the paucity of empirical evidence are examined. Finally, the trends observed in Poland are interpreted within the larger context of contemporary European migration.

  2. POLAND AND TRANSATLANTIC SECURITY - AN ENDURING ATLANTICIST?

    2005-07-01

    Full Text Available Throughout the 1990’s Poland pursued a security policy steered by Atlanticism and a close bond with the United States. Atlanticism shaped Warsaw’s choices on all key security issues during the past decade, but became particularly apparent after 9/11 when Poland lent its full support to the US-led war on terror. Whilst membership in the EU will affect the priorities and conduct of Polish security policy, it is argued here that the deep-seated nature of Atlanticism in Polish strategic culture , together with the broader implications of enlargement upon the EU’s foreign policy ambitions will ensure that Poland will remain a keen Atlanticist in the New Europe.

  3. Constraining the deformation and exhumation history of the Ronda Massif, Southern Spain

    2016-04-01

    The Ronda peridotite, southern Spain is comprised of four peridotite units hosted within metasedimentary units of the Betic Cordillera, Western Alps. These four areas of differing mineral facies are termed: the Garnet Mylonite , the Foliated Spinel Peridotite, the Granular Spinel Peridotite and the Foliated Plagioclase Peridotite. Whilst two of these units show a strong NE-SW foliation, the granular unit has no foliation and the Plagioclase facies shows a NW-SE foliation. The massif is separated from the metasedimentary host through a mylonite shear zone to the NW and thrust faults to the SE. The Garnets contain rims of Kelyphite which when combined with the rims of Spinel on the Plagioclase crystals illustrate the complicated exhumation of this massif. The Kelyphite shows the breakdown of garnet back to spinel and pyroxene showing the deeper high pressure high temperature mineral is under shallowing conditions whereas in contrast to this the low pressure low temperature plagioclase crystals have spinel rims showing that they have been moved into deeper conditions. The P-T-t pathway of the massif suggests slow exhumation to allow for partial recrystallisation of not only the garnets and plagioclases but of a 100m band of peridotite between the Foliated Spinel Peridotite and the Granular Spinel Peridotite facies. The tectonic model for the Ronda Peridotite that best describes the field data and subsequent lab work of this study is Mantle Core complex and slab roll back models. These models support mantle uprising during an extensional event that whereby slab roll back of the subducting lithosphere provides uplift into a void and emplacement into the crust. Further extension and final exhumation causes rotation of a mantle wedge into its present day position.

  4. Viral hepatitis as an occupational disease in Poland.

    2011-07-01

    In medical terms, occupational diseases are defined as health disorders specifically associated with the working environment of people and their occupational activity. From the medical and legal perspectives, the vast majority of European countries consider particular diseases to be of occupational origin if they are mentioned in the current list of occupational diseases and caused by exposure to factors in the working environment that are harmful to health. The aim of this study was to analyze the occurrence of cases of viral hepatitis certified as an occupational disease in Poland during 1979-2009. This article presents the medical, economic, and legal aspects of the epidemiology of hepatitis as an occupational disease in Poland. Publically available statistical data on certified occupational diseases in Poland and data contained in individual "occupational disease diagnosis cards" (based on data used in Poland statistical form), regarding certified cases of hepatitis among health care professionals, which were collected by the Department of Occupational Hygiene of the Polish Public Health Service, were analyzed in this study. In Poland, the highest number of cases of hepatitis certified as an occupational disease was observed in 1987. A gradual reduction in the number of cases of hepatitis as an occupational disease has been noted since then. Currently, hepatitis C as an occupational disease is certified more frequently than hepatitis B. In Poland, the number of women with hepatitis certified as an occupational disease is higher than that of men. However, among health care professionals, particularly nurses, this difference is insignificant because women outnumber the men. The existence of such a situation is due to the significant quantitative predominance of women over men among medical personnel, especially among nurses. Immunization of health care professionals against the hepatitis B virus (HBV), introduced in Poland in 1988, was an important factor

    Full Text Available Two peat bogs were studied in the Bory Dolnośląskie, the forest complex in Lower Silesia (Poland. An Instorf drill was used to collect two peat profiles from the deepest places. The macroremains analysis showed that after the initiation of peat-forming processes phytocoenoses responsible for the deposition of transition sphagnum peat were developed at both locations. Later on, the development of both peat bogs differed. The smaller peat bog continued to develop, whereas the big bog was shifted to ombrotrophic water regime. Therefore, phytocoenoses accumulated 1.3 m of Sphagnum peat. The peat-forming process was initiated at different times in both sites. For the smaller peat bog, it took place during the Atlantic period, while in the case of the larger peat bog – several thousand years later. The first identified forest phytocoenoses in the Atlantic period are mesophilic multi-species deciduous forests. Dry coniferous forests and mixed birch-pine forests grew in dry habitats. Riparian forests occupied lower grounds. In the Subboreal period, the oak–hazel communities initially developed and mixed coniferous forests were partially replaced by light oak forests. The encroachment of spruce, fir, hornbeam, and beech resulted in the development of dry ground forests, including beech–fir woods. The importance of riparian forests increased, whereas in dry grounds pine and mixed coniferous forests continued to occur. In the Subatlantic period, the transformations in forest communities were associated with the spread of hornbeam, beech, and fir and thereby vast fertile habitats were colonized by dry ground communities and beech woods. Pine and mixed forests as well as riparian forests were of lesser importance. Pollen records from the last 500 years showed the clear presence of humans. It was evident from the presence of cereal and weed pollen and from the disturbances in the pollen records caused by peat extraction in the Middle Ages.

    Adiaspiromycosis is a rare fungal infection caused by saprophytic fungi Emmonsia spp. (type Ascomycota) occurring especially in small free-living mammals. The aim of this study was to evaluate the occurrence of histopathological lesions asscociated with adiaspiromycosis in the Eurasian beaver inhabiting Poland. In order to evaluate the presence of natural adiaspiromycosis we systematically investigated beaver populations from north-eastern Poland for adiaspores in the lungs. This study reveals for the first time the presence of pulmonary adiaspiromycosis of Eurasian beaver in Poland. As far as we know, there is no published data regarding pulmonary adiaspiromycosis in human patients in Poland.

    In Poland the radioactive contamination of the environment and food has been controlled since the early sixties by the Service for Measurements of Radioactive Contamination (SPSP). The service comprises a network of measuring stations and the Centre of Radioactive Contamination Measurements (COPSP). Actually, there are 100 measurement stations. The main task of such station is systematic measurement of radioactivity level in samples of environment components and food. Nine stations of SPSP acting within meteorological stations, ten stations of low level air radioactivity measurements (Aerosols Sampling Stations-500) and eleven permanent monitoring stations (PMS) form the radiation monitoring warning system in Poland.

    Serpentinization of mantle peridotite has been recognized as one of the most important energy factories for the deep biosphere. To better evaluate the habitability of the deep biosphere, it is crucial to understand the link between in situ peridotite serpentinization processes and associated magnetite and hydrogen production. Previous efforts in correlating magnetite and hydrogen production during serpentinization processes are based primarily on laboratory experiments and numerical modeling, being challenged to include the contribution of superparamagnetic-sized magnetites (i.e., extremely fine-grained magnetite, petrographically observed as a "pepper flake" like texture in many natural serpentinized rock samples). To better estimate the abundance of superparamagnetic grains, we conducted frequency-dependent susceptibility magnetic measurements at the Institute of Rock Magnetism on naturally serpentinized rock samples from the Coast Range Ophiolite Microbial Observatory (CROMO) in California, USA and the Atlin Ophiolite (British Columbia). In addition, we conducted multiscale EDS phase mapping, BackScattered Electron (BSE) scanning, FIB-nanotomography and STEM-EELS to identify and quantify the superparamagnetic minerals that contribute to the measured magnetic susceptibility signals in our rock samples. Utilizing a multidisciplinary approach, we aim to improve the estimation of hydrogen production based on the abundance of magnetite, that includes the contribution of superparamagnetic particle size magnetite, to ultimately provide a more accurate estimation of bulk deep-biomass hosted by in situ serpentinization processes.

    Full Text Available The main purpose of this work is to analyse the phenomenon of enterprises’ bankruptcy in Poland in 2004-2013 and attempt to build regression models defining the relationship between the number of bankrupted companies and selected macroeconomic parameters of the national economy. The analysis is based on Coface Poland reports presenting the phenomenon of bankruptcy in Poland of branches, provinces, legal forms of companies and types of bankruptcy proceedings. Studies have shown that the greatest risk of bankruptcy refers to metals production and fabricated metal products enterprises, manufacture of food products and beverages, wholesale trade, construction, micro and small enterprises, enterprises under the age of 10 years and companies from Mazovia region, Silesia and Lower Silesia. The estimated parameters of the regression models showed that the number of bankruptcies in Poland is strongly determined i.a. by the number of registered companies, GDP growth, dynamics of changes in fixed capital formation and changes in foreign exchange rates.

    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.

    2010-02-01

    This review presents the past and the present of pediatric neurology in Poland. Pediatric neurology has its roots in Polish general neurology represented by many outstanding scientists. The founder of Polish school of neurology at the end of 19th century was Edward Flatau, known as the author of Flatau's law. The most famous Polish neurologist was Joseph Babiński, recognized for the first description of pathological plantar reflex. First Polish publication related to child neurology was Brudziński's report on a new meningeal symptom (the flexion of lower limbs during passive neck flexion with pain in neck). Contemporary child neurology in Poland was created by Professor Zofia Majewska after the Second World War. Now 10 academic centers of child neurology exist in Poland fulfilling educational, scientific, and therapeutic roles. Polish Society of Child Neurology was established in 1991 and now there are about 580 members, including 300 child neurologists.

    The objective of this study was to describe the epidemiology of imported malaria in Poland in 2010 in comparison to previous years. The study included malaria cases that were collected and registered by the State Sanitary Inspection in 2010 in Poland. Data reported was verified, processed and published by National Institute of Public Health - National Institute of Hygiene. All cases were laboratory confirmed by blood film, polymerase chain reaction or rapid diagnostic tests outlined by the EU case definition. Differences in the distribution of demographic, parasitological and clinical characteristics, and incidence were analyzed. In 2010, a total of 35 confirmed malaria cases were notified in Poland, 13 more than 2009. All cases were imported, 49% from Africa, including 1 case with relapsing malaria caused by P. vivax and 2 cases of recrudescence falciparum malaria following failure of treatment. The number of cases acquired in Asia (37% of the total), mainly from India and Indonesia, was significantly higher than observed in previous years. Among cases with species-specific diagnosis 19 (63%) were caused by P. falciparum, 9 (30%) by P. vivax, one by P. ovale and one by P. malariae. The median age of all cases was 42 years (range 9 months to 71 years), males comprised 69% of patients, females 31%, three patients were Indian citizens temporarily in Poland. Common reasons for travel to endemic countries were tourism (57%), work-related visits (37%), one person visited family and in one case the reason for travel was unknown. Sixteen travelers took chemoprophylaxis, but only three of them appropriately (adherence to the recommended drug regimen, continuation upon return and use of appropriate medicines). In 2010, there were no deaths due to malaria and clinical course of disease was severe in 7 cases. When compared with 2009, there was a marked increase in the number of imported malaria cases in Poland, however the total number of notified cases remained low. Serious

  5. Challenges for developing national climate services – Poland and Norway

    Full Text Available This contribution discusses the challenges for developing national climate services in two countries with high fossil fuel production – Poland (coal and Norway (oil and gas. Both countries, Poland and Norway, have highly developed weather services, but largely differ on climate services. Since empirical and dynamical downscaling of climate models started in Norway over 20 years ago and meteorological and hydrological institutions in Oslo and Bergen have been collaborating on tailoring and disseminating downscaled climate projections to the Norwegian society, climate services are now well developed in Norway. The Norwegian Centre for Climate Services (NCCS was established in 2011. In contrast, climate services in Poland, in the international understanding, do not exist. Actually, Poland is not an exception, as compared to other Central and Eastern European countries, many of which neither have their national climate services, nor are really interested in European climate services disseminated via common EU initiatives. It is worth posing a question – can Poland learn from Norway as regards climate services? This contribution is based on results of the CHASE-PL (Climate change impact assessment for selected sectors in Poland project, carried out in the framework of the Polish – Norwegian Research Programme. The information generated within the Polish-Norwegian CHASE-PL project that is being broadly disseminated in Poland can be considered as a substitute for information delivered in other countries by climate services.

  7. Poland: A Dark Side of Church Cultural Policy

    Directory of Open Access Journals (Sweden)

    Szocik Konrad

    2015-12-01

    Full Text Available The cultural policy of the Roman Catholic Church in Poland is incorporated into state-run cultural policies. The organs of public authority enforce the objectives of Church regardless of Church’s actual ability to influence the society. It should be pointed out that the secularization of religion in Poland is frequently misinterpreted and usually equated with its deprivatization. It is worth mentioning that Catholicism is the dominant religion of the country and the Roman Catholic Church has hold a special position in Poland and play a major role in the country’s social and political life. In practice, however, Polish society appears to be religiously indifferent. This paper proves that the official, state-run cultural policy in Poland is based on favoritism of the Roman Catholic Church, regardless of Church’s actual ability to wield influence on society. Thus, there is a variety of implicit and explicit cultural policies implemented by the authorities to support Church. This work also aims at addressing the question of social attitudes to women, especially the one concerning the UN and EU law embracing women’s rights, until recently still not implemented in Poland. This paper further explores some peculiarities of this topic as an example of a specific outcome of Church cultural policy and its impact on both the past and present-day society.

    In 1997, a new energy law was passed in Poland. An important element of the law is that local energy is made obligatory. The law describes obligatory tasks and procedures for the Polish municipalities related to planning and organisation of the energy sector. With the objective of supporting the Polish municipalities in their obligations according to the energy law, the project 'Energy Planning in Poland at Municipal Level - Support to Decision Makers' was launched. As part of the project, Municipal Guideline Reports have been elaborated for three model municipalities. These guidelines present the basis for energy supply plans in the three municipalities. For the city of Legionowo, the following was recommended: 1. The planning processes initiated during the project should be continued/followed up, 2. Master Plan for the district heating system should be prepared, 3. The possibilities of establishment of a major natural gas-fired CHP plant of the combined cycle type should be investigated. The present report describes the electricity market in Poland, the market in which a CHP plant in Legionowo will have to operate. Furthermore the report presents the results of the feasibility analysis carried out for a new CHP plant in Legionowo. (BA)

  11. [Poland: cholera to typhus, 1831-1950].

    Balinska, M A

    In this article devoted to Poland's direct and indirect role in the elaboration of contemporary international health structures and to her reputation as an epidemic reservoir of Europe, we consider how Poland came to be perceived as the cordon sanitaire of the West. Traditionally seen as upholding Western values, in the 19th and 20th centuries the country became increasingly associated with "Eastern plagues"-cholera and then typhus-coming from Russia and which could spread to the rest of Europe if Poland did not manage to contain them. When Poland was reconstituted as a nation-state in 1918, the new country won international recognition through her successful attempts to contain a typhus epidemic sweeping westwards from Russia. The Polish government convened the first European, League sponsored, health conference following the First World War. A Polish doctor, L. RAJCHMAN, was chosen to head up the League of Nations Health Organisation (forerunner of the WHO) and later (1946) founded UNICEF. Finally, we examine the key issue of exanthematous typhus in both world wars, exemplifying how a disease can come to be "ideologized", in this case by Nazi Germany. Typhus was the pretext used- in the name of "public health"-for segregating Polish citizens of Jewish origin and even killing them. Paradoxically, typhus was in the process of being eradicated when the war began and German policy of mass resettlements, sequestration, and starvation only spurred the epidemic they supposedly wished to control.

  12. Origin of Fe-rich lherzolites and wehrlites from Tok, SE Siberia by reactive melt percolation in refractory mantle peridotites

    2005-10-01

    Lherzolite-wehrlite (LW) series xenoliths from the quaternary Tok volcanic field in the southeastern Siberian craton are distinguished from the more common lherzolite-harzburgite (LH) series by (a) low Mg numbers (0.84-0.89) at high modal olivine (66-84%) and (b) widespread replacement of orthopyroxene (0-12%) and spinel by clinopyroxene (7-22%). The LW series peridotites are typically enriched in Ca, Fe, Mn and Ti, and depleted in Si, Ni and Cr relative to refractory LH series rocks (Mg number ≥0.89), which are metasomatised partial melting residues. Numerical modelling of Fe-Mg solid/liquid exchange during melt percolation demonstrates that LW series rocks can form by reaction of host refractory peridotites with evolved (Mg numbers 0.6-0.7), silica-undersaturated silicate melts at high melt/rock ratios, which replace orthopyroxene with clinopyroxene and decrease Mg numbers. This process is most likely related to underplating and fractionation of basaltic magma in the shallow mantle, which also produced olivine-clinopyroxene cumulates found among the Tok xenoliths.

    2006-01-01

    The paper presents results on determination of 90 Sr in bilberry and cowberry leaves (Vaccinium myrtillus and Vaccinium vitis-idaea) and the use of these plants as bio-monitors of radiostrontium contamination in Poland. Radiostrontium was determined by mean of liquid scintillation spectrometry preceded by radiochemical separation using Sr-resin and 85 Sr tracer. The approximate map of 90 Sr contamination of Poland is presented. The activity ratio between 90 Sr and obtained earlier data for 137 Cs in the same samples is discussed. The enhancement of radiostrontium content observed in northeastern Poland seems to be the trace of hot-particles fallout from initial Chernobyl cloud, which passed over Polish territory toward Scandinavia.

    In Poland 48 measles cases were registered in 2003 (0.13 per 100,000 population)--of which 65% were cases imported from Chechnya and Afghanistan. Measles outbreaks occurred in 3 centers for immigrants. In total, 31 cases were reported, of which 96.8% were unvaccinated, and 93.5% were under 15 years of age. Of 17 local cases, 5 (29.4%) cases occurred in unvaccinated persons, 3 (17.6%) in persons vaccinated with one dose and 7 (41.2%) in those vaccinated with two doses of measles vaccine (administered at the age of 13-15 months and 7 years). Among 12 vaccinated cases only one 2-year old child was recently vaccinated. The remaining cases were in the 3-7 and 10-24 age ranges. The most affected were infants (incidence 0.57 per 100,000), 1-year old (0.28) and 2-year old children (incidence 0.27). Cases among adolescents and adults over 15 years of age increased from 23.5% in 2002 to 47.1% in 2003. The increasing age of locally-acquired cases, together with constantly high immunization coverage indicates high effectiveness of vaccinations in Poland. Out of all reported cases 13 (38%) were hospitalized. There were no deaths due to measles in Poland in 2003. Poland participates in the WHO Measles Elimination Strategy. Presently, the most important is the maintenance of a sensitive and timely surveillance of measles and measles-compatible cases, with serologic confirmation of one rash-like illness per 100 000 population. The performance of the surveillance system is insufficient with only 55 measles-compatible cases reported in 2003 (15% of expected reports). Serologic confirmation of cases was also insufficient, with 22 cases (40.0%) confirmed by IgM ELISA test. These results indicate the need to maintain the high immunisation coverage and improve measles surveillance system.

    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.

    Fernandez, Ignacio; Di Cerbo, Antonio; Dehnhardt, Erik; Massimo, Tipaldi; Brünjes, Bernhard

    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.

    Full Text Available Introduction. In 2012, China became the largest spender in international tourism, benefiting many destinations worldwide. Even if for Poland it is not an important source market yet, the Polish authorities have undertaken some marketing activities in China. The main aim of the paper is to explore the profile, motivations, and perceptions of the Chinese tourists visiting Cracow. The secondary aim is to check the effectiveness of the marketing efforts dedicated to the Chinese market undertaken by Poland since 2010. Material and methods. Data for the study (n = 100 were collected using a paper survey in English carried out among mainland Chinese tourists in Cracow in 2015. Results. The Chinese usually visit Poland for the first time, often in transit. They are prompted by the information found online and by word of mouth. Their main reasons to come are tradition, culture, historical sites, landscapes, and low costs. These expectations are well fulfilled, and the tourists′ overall satisfaction is very high. The Chinese find Poland to be different from other Western European countries. For them, Poland is a remarkable, traditional, safe, and developing country. Yet, their knowledge about the destination is limited. The main problem encountered is the language barrier, both online and once on site. The marketing efforts undertaken by Poland in the Chinese market have had weak and ambivalent effects. Conclusions. In order to attract Chinese tourists, there is a need to intensify expenditure not only on promotion (mainly online but also on the removal of language-based communication problems. There is also scope for expanding the tourist offer dedicated to Chinese tourists - both in Poland and in cooperation with other Central European countries.

  8. Energy use in Poland, 1970--1991: Sectoral analysis and international comparison

    Energy Technology Data Exchange (ETDEWEB)

    Meyers, S.; Schipper, L.; Salay, J.

    1993-07-01

    This report provides an analysis of how and why energy use has changed in Poland since the 1970s, with particular emphasis on changes since the country began its transition from a centrally planned to a market economy in 1989. The most important factors behind the large decline in Polish energy use in 1990 were a sharp fall in industrial output and a huge drop in residential coal use driven by higher prices. The structural shift away from heavy industry was slight. Key factors that worked to increase energy use were the rise in energy intensity in many heavy industries and the shift toward more energy intensive modes of transport. The growth in private activities in 1991 was nearly sufficient to balance out continued decline in industrial energy use in that year. We compared energy use in Poland and the factors that shape it with similar elements in the West. We made a number of modifications to the Polish energy data to bring it closer to a Western energy accounting framework, and augmented these with a variety of estimates in order to construct a sufficiently detailed portrait of Polish energy use to allow comparison with Western data. Per capita energy use in Poland was not much below W. European levels despite Poland`s much lower GDP per capita. Poland has comparatively high energy intensities in manufacturing and residential space heating, and a large share of heavy industries in manufacturing output, all factors that contribute to higher energy use per capita. The structure of passenger and freight transportation and the energy intensity of automobiles contribute to lower energy use per capita in Poland than in Western Europe, but the patterns in Poland are moving closer to those that prevail in the West.

    Ultramafic rocks are relatively rare at the Earth's surface but constitute the vast majority of the Earth by volume. Exposures of ultramafic bodies are therefore crucial for deducing many important processes that occur in the Earth's mantle. An important science question regarding the spatial distribution, abundance, and composition of mafic minerals in ultramafic bodies that can be examined with advanced sensor data is the melting process. When a lherzolite melts, clinopyroxene (cpx) melts first and therefore variations in the modal amount of cpx remaining in the mantle are a reflection of the amount of fractional melting that has occurred. Fe goes preferentially into the melt during melting but a 20 percent batch melting (i.e. closed system) acquires less Fe relative to 20 percent fractional melting (i.e. open system). Since the strength and wavelength of diagnostic absorptions is a strong function of Fe content, it is possible to make maps of the variation in Fe:Mg ratios which can be related to the general melting process. Accurate ground-truth information about local mineralogy provides internal calibration and consistency checks. Investigations using imaging spectrometer are very complementary to field studies because advanced sensor data can provide a synoptic view of modal mineralogy and chemical composition whereas field studies focus on detailed characterization of local areas. Two excellent exposures of ultramafic lithologies are being investigated with visible to mid-infrared imaging spectrometer data: the Ronda peridotite near Ronda, Spain and the Beni Bousera ophiolitic fragment in northern Morocco. Although separated by the Alboran Sea, these bodies are thought to be related and represent fertile sub-continental mantle. The Ronda peridotite is predominantly spinel lherzolite but grades into harzburgite and shows considerable variation in major and trace element compositions. Mafic layering and dykes (i.e. olivine gabbro) are also observed. This

    Lyme disease is the most common tick-borne disease in Poland. Borrelia burgdorferi spirochete can occur in the whole country, which, according to ECDC, should be considered as an endemic area. Borrelia strains are transmitted to humans and certain other animals by Ixodes (1). Human infection is caused by saliva or tick vomit. Reservoir spirochete are numerous species of animals, mainly rodents. Lyme disease, due to its multifocal character, rich symptomatology and diagnostic problems, is a serious challenge for clinicians and epidemiologists The aim of this study was to assess the epidemiological situation of Lyme disease in Poland in 2015 in comparison to the previous years The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletin “Infectious diseases and poisonings in Poland in 2015” (2) Despite observed in recent years the tendency to growth of number of cases, in 2015 was marked by growth inhibition incidence of Lyme disease.In 2015, 13 625 cases were registered in Poland, ie by 0.7% less than in the previous year. The overall incidence in the country was 35.4 per 100 000 population - the highest was recorded in the Podlaskie voivodeship - 96.3 per 100 000 inhabitants. In 2015, 1905 (14%) people were hospitalized due to Lyme disease In 2015, for the first time in a few years, the growth rate of Lyme disease has been stopped. Registered 0.7% less cases than in the previous year. There is still a need for bringing awareness of the need for diagnostic laboratory testing according to recommendations, which will improve the accuracy of the diagnosis

    2017-12-01

    The characteristics of extreme precipitation, including the dominant trends, were analysed for eight stations located in different parts of Poland for the period 1951-2010. Five indices enabling the assessment of the intensity and frequency of both extremely dry and wet conditions were applied. The indices included the number of days with precipitation ≥10mm·d-1 (R10), maximum number of consecutive dry days (CDD), maximum 5-day precipitation total (R5d), simple daily intensity index (SDII), and the fraction of annual total precipitation due to events exceeding the 95th percentile calculated for the period 1961-1990. Annual trends were calculated using standard linear regression method, while the fit of the model was assessed with the F-test at the 95% confidence level. The analysed changes in extreme precipitation showed mixed patterns. A significant positive trend in the number of days with precipitation ≥10mm·d-1 (R10) was observed in central Poland, while a significant negative one, in south-eastern Poland. Based on the analysis of maximum 5-day precipitation totals (R5d), statistically significant positive trends in north-western, western and eastern parts of the country were detected, while the negative trends were found in the central and northeastern parts. Daily precipitation, expressed as single daily intensity index (SDII), increased over time in northern and central Poland. In southern Poland, the variation of SDII index showed non-significant negative tendencies. Finally, the fraction of annual total precipitation due to the events exceeding the 1961-1990 95th percentile increased at one station only, namely, in Warsaw. The indicator which refers to dry conditions, i.e. maximum number of consecutive dry days (CDD) displayed negative trends throughout the surveyed area, with the exception of Szczecin that is a representative of north-western Poland.

    Escario, S.; Godard, M.; Gouze, P.; Leprovost, R.; Luquot, L.; Garcia-Rios, M.

    2017-12-01

    Mantle peridotites have the potential to trap CO2 as carbonates. This process observed in ophiolites and in oceanic environments provides a long term and safe storage for CO2. It occurs as a part of a complex suite of fluid-rock reactions involving silicate dissolution and precipitation of hydrous phases, carbonates and minor phases that may in turn modify the hydrodynamic properties and the reactivity of the reacted rocks. The efficiency and lastingness of the process require the renewal of fluids at the mineral-fluid interface. Fractures are dominant flow paths in exhumed mantle sections. This study aims at better understanding the effect of CO2-enriched saline fluids on hydrodynamic and chemical processes through fractured peridotites. Experiments were performed using the reactive percolation bench ICARE Lab 3 - Géosciences Montpellier. It allows monitoring the permeability changes during experiments. Effluents are recurrently sampled for analysing cation concentration, pH and alkalinity. Reacted rock samples were characterized by high resolution X-ray microtomography (ESRF ID19, Grenoble, France) and SEM. Experiments consisted in injecting CO2-enriched brines (NaCl 0.5 M) at a rate of 6 mL.h-1 into artificially fractured cores (9 mm diameter × 20 mm length) of Oman harzburgites at T=170°C and Ptotal = 25 MPa for up to 2 weeks. Fractures are of few µm apertures with rough walls. Three sets of experiments were performed at increasing value of [CO2] (0, 0.1 and 1 mol/kg). All experiments showed a decrease in permeability followed by steady state regime that can be caused by a decrease in the roughness of fracture walls (dissolution dominated process), thus favouring fracture closing, or by the precipitation of secondary phases. Maximum enrichments in Mg, Fe and Ca of the effluent fluids occur during the first 2 hours of the experiments whereas Si displays a maximum enrichment at t = 20 h, suggesting extensive dissolution. Maximum enrichments are observed with

    As one of the slowest spreading ridges of the global ocean ridge system, the Southwest Indian Ridge (SWIR) is characterized by discontinued magmatism. The 53°E segment between the Gallieni fracture zone (FZ) (52°20'E) and the Gazelle FZ (53°30'E) is a typical amagmatic segment (crustal thickness 1cm) Opx, and Mg-rich mineral compositions akin to harzburgite xenoliths that sample old continental lithospheric mantle (Kelemen et al., 1998). Melt refertilization model shows that Group 2 peridotites were affected by an enriched low-degree partial melt from the garnet stability field. These results indicate that depleted mantle which experiences ancient melting event are more sensitive to melt refertilization, thus may reduce the melt flux, leading to extremely thin crust at 53°E segment.

    The study objective was to evaluate quantitatively the relationship between demographic characteristics, socio-economic status and medical care resources with all cause mortality in Poland. Ecological study was performed using data for the population of 66 subregions of Poland, obtained from the Central Statistical Office of Poland. The information on the determinants of health and all cause mortality covered the period from 1st January 2005 to 31st December 2010. Results for the repeated measures were analyzed using Generalized Estimating Equations GEE model. In the model 16 independent variables describing health determinants were used, including 6 demographic variables, 6 socio-economic variables, 4 medical care variables. The dependent variable, was age standardized all cause mortality rate. There was a large variation in all cause mortality, demographic features, socio-economic characteristics, and medical care resources by subregion. All cause mortality showed weak associations with demographic features, among which only the increased divorce rate was associated with higher mortality rate. Increased education level, salaries, gross domestic product (GDP) per capita, local government expenditures per capita and the number of non-governmental organizations per 10 thousand population was associated with decrease in all cause mortality. The increase of unemployment rate was related with a decrease of all cause mortality. Beneficial relationship between employment of medical staff and mortality was observed. Variation in mortality from all causes in Poland was explained partly by variation in socio-economic determinants and health care resources.

    The main objective of the THERMIE Associated Measure WE05 is to study market conditions and estimate the market for wind power in Eastern Europe. This report describes the results of a study of the conditions in Poland, which has been concentrated on the following areas: wind energy potential in Poland; data concerning the present structure of the power production system including costs; payback prices, subsidies, etc. with relation to renewable energy sources, especially wind power; information on existing wine turbines and their production in Poland; possibilities for co-production of wind turbines by Polish and EC factories, and rules and legislation pertaining to the establishment of wind turbines and to power production by wind, eg regulations related to grid connection, safety and environment. According to existing data there are possibilities for using the wind potential in certain parts of poland. The wind data have to be improved if particular sites are considered for wind parks. The current official plans concerning the energy system have taken renewable sources into consideration, including wind power that is estimated to contribute ∼ 1 GWh by 2005-2010. Wind turbines may be connected to the public grid with due regard to the strength of the line. Presently, the owner has to pay all the costs, however, new rules are under consideration. The conditions for the connection and operation of wind turbines have to be discussed with the particular utility on an an-hoc basis. (EG)

    Full Text Available In 2017 statistics showed that Chinese Foreign Direct Investments (FDI in Poland for 2016 amounted to a more than half of all Chinese FDI in Poland for the 2000–2016. Yet the overall amount of Chinese FDI remains modest in comparison with Western Europe or even with Hungary. Despite much proclaimed Sino-Polish rapprochement in 2015–2016 and high hopes for OBOR/BRI initiative in Poland, cooperation with China has not been a breakthrough for Poland in terms of economic results. There have not been ground-breaking Sino-Polish projects and Polish government’s desire to strengthen ties with China loosened in late 2016/early 2017 (though it may revive now.There are several reasons for that, from the perception of Poland as non-attractive for majority Chinese investments, via lack of overall Polish strategy of attracting these investors to discrepancies of economic interests between Poland and China.

    Accurate maps of Earth's geology, especially its regolith, are required for managing the sustainable exploration and development of mineral resources. This paper shows how airborne imaging hyperspectral data collected over weathered peridotite rocks in vegetated, mountainous terrane in New Caledonia were processed using a combination of methods to generate a regolith-geology map that could be used for more efficiently targeting Ni exploration. The image processing combined two usual methods, which are spectral feature extraction and support vector machine (SVM). This rationale being the spectral features extraction can rapidly reduce data complexity by both targeting only the diagnostic mineral absorptions and masking those pixels complicated by vegetation, cloud and deep shade. SVM is a supervised classification method able to generate an optimal non-linear classifier with these features that generalises well even with limited training data. Key minerals targeted are serpentine, which is considered as an indicator for hydrolysed peridotitic rock, and iron oxy-hydroxides (hematite and goethite), which are considered as diagnostic of laterite development. The final classified regolith map was assessed against interpreted regolith field sites, which yielded approximately 70% similarity for all unit types, as well as against a regolith-geology map interpreted using traditional datasets (not hyperspectral imagery). Importantly, the hyperspectral derived mineral map provided much greater detail enabling a more precise understanding of the regolith-geological architecture where there are exposed soils and rocks.

  5. Organic food consumption in Poland: Motives and barriers.

    2016-10-01

    This paper aims to investigate selected aspects of organic food consumption in Poland. We conducted a survey in a representative sample of 1000 consumers. Polish consumers are convinced that organic food is more expensive, healthier, more environmentally friendly, more tasty and more authentic than conventional food. They believe its arouses more trust, has a better quality, is subject to more strict controls, and is produced in a more traditional way. According to Polish consumers, the most important characteristics of organic food are healthiness and high quality. The perceived authenticity of organic food depends on its natural taste, product quality, labelling, in particular having a European quality sign, as well as the retailer type and a separate exposition place in the points of purchase (merchandising). The critical barrier to the development of the organic food market in Poland is the high price, followed by an insufficient consumer awareness, low availability of organic products, short expiry dates and low visibility in the shop. The principal motives of organic food selection in Poland include: healthiness, ecological character of the product, food safety considerations, superior taste, and quality assurance. We identified the motives for and barriers to organic food consumption in Poland. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2016-04-01

    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

    Within a constrained carbon environment, the risks of future natural gas supply, and the need to move to market-based electricity prices, the study team found: (1) the deployment of new nuclear energy in Poland itself is very competitive in the next decade or two; (2) if such generation could be made available to Poland prior to deployment of its own nuclear generation facilities, Poland would benefit from partnering with its Baltic neighbors to import electricity derived from new nuclear generation facilities sited in Lithuania; and (3) Poland appears to be a good candidate for a partnership in the Global Nuclear Energy Partnership (GNEP) as an emerging nuclear energy country.

  11. On SW-minimal models and N=1 supersymmetric quantum Toda-field theories

    International Nuclear Information System (INIS)

    Mallwitz, S.

    1994-04-01

    Integrable N=1 supersymmetric Toda-field theories are determined by a contragredient simple Super-Lie-Algebra (SSLS) with purely fermionic lowering and raising operators. For the SSLA's Osp(3/2) and D(2/1;α) we construct explicitly the higher spin conserved currents and obtain free field representations of the super W-algebras SW(3/2,2) and SW(3/2,3/2,2). In constructing the corresponding series of minimal models using covariant vertex operators, we find a necessary restriction on the Cartan matrix of the SSLA, also for the general case. Within this framework, this restriction claims that there be a minimum of one non-vanishing element on the diagonal of the Cartan matrix. This condition is without parallel in bosonic conformal field theory. As a consequence only two series of SSLA's yield minimal models, namely Osp(2n/2n-1) and Osp(2n/2n+1). Subsequently some general aspects of degenerate representations of SW-algebras, notably the fusion rules, are investigated. As an application we discuss minimal models of SW(3/2, 2), which were constructed with independent methods, in this framework. Covariant formulation is used throughout this paper. (orig.)

  12. Contrasting styles of Sn-W mineralisation in peninsular Thailand and SW England

    Science.gov (United States)

    Manning, D. A. C.

    1986-01-01

    The Sn-W deposits of SW England and SE Asia are associated with crustally derived granitic rocks with late volatile-enriched (F, Li, B, P) differentiates. In peninsular Thailand, primary ores are principally pegmatitic, and hydrothermal vein systems are only locally important. In SW England, wolframite and cassiterite mainly occur in hydrothermal vein systems, and are associated with greisening and tourmalinisation; mineralised pegmatites are rare. These two styles of mineralisation are thought to arise because of differences in the character of late magmatic processes. In peninsular Thailand, late-stage tourmaline-bearing granitic rocks are enriched in B, but not Li and F, compared to earlier biotite granites. Similar late-stage granitic rocks occur also in SW England, but a later topaz granite, enriched in F, Li and P, also occurs. The Thai pegmatitic Sn-W deposits are thought to have formed by late magmatic crystallisation from an aqueous phase enriched in metals and derived by exsolution from a B and metal-rich magma, whereas the SW England mineralisation involved essentially post-magmatic hydrothermal processes. Complexing agents (especially F) and metals may have been derived from granitic or country rocks during hydrothermal circulation at the current level of emplacement.

  15. Dynamics of Melting and Melt Migration as Inferred from Incompatible Trace Element Abundance in Abyssal Peridotites

    Peng, Q.; Liang, Y.

    2008-12-01

    To better understand the melting processes beneath the mid-ocean ridge, we developed a simple model for trace element fractionation during concurrent melting and melt migration in an upwelling steady-state mantle column. Based on petrologic considerations, we divided the upwelling mantle into two regions: a double- lithology upper region where high permeability dunite channels are embedded in a lherzolite/harzburgite matrix, and a single-lithology lower region that consists of partially molten lherzolite. Melt generated in the single lithology region migrates upward through grain-scale diffuse porous flow, whereas melt in the lherzolite/harzburgite matrix in the double-lithology region is allowed to flow both vertically through the overlying matrix and horizontally into its neighboring dunite channels. There are three key dynamic parameters in our model: degree of melting experienced by the single lithology column (Fd), degree of melting experienced by the double lithology column (F), and a dimensionless melt suction rate (R) that measures the accumulated rate of melt extraction from the matrix to the channel relative to the accumulated rate of matrix melting. In terms of trace element fractionation, upwelling and melting in the single lithology column is equivalent to non-modal batch melting (R = 0), whereas melting and melt migration in the double lithology region is equivalent to a nonlinear combination of non-modal batch and fractional melting (0 abyssal peridotite, we showed, with the help of Monte Carlo simulations, that it is difficult to invert for all three dynamic parameters from a set of incompatible trace element data with confidence. However, given Fd, it is quite possible to constrain F and R from incompatible trace element abundances in residual peridotite. As an illustrative example, we used the simple melting model developed in this study and selected REE and Y abundance in diopside from abyssal peridotites to infer their melting and melt migration

    The behavior of the poly(methyl methacrylate) (PMMA) under the action of gamma radiation has been sufficiently studied. In this work, we present results from melt flow index (MFI), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and electron paramagnetic resonance (EPR) of PMMA composites with hydroxyapatite (HA) and seaweed residues (SW) irradiated with gamma rays at 1.08 kGy/h. Composites of PMMA/HA and PMMA/SW with 10%, 20% and 30% of the filler were prepared. The results show an increase in the MFI values with the integral dose of radiation, being consistent with chain-scission reactions. No EPR signal was observed in pure PMMA, while in the composites, the typical EPR signal of the PMMA radicals was observed, which increased with the amount of HA or SW. When comparing the relative intensities of the EPR signals for both types of composites, a slight increase in the concentration of free radicals generated in the sample with SW respect to that of PMMA/HA composite was obtained. A decay of the total free radical concentration was observed as time elapsed.

    Based on new and previously published Sr and Nd isotope data, we examined the petrogenetic relationship between deep crust- and upper mantle-derived xenoliths contained in Cenozoic volcanic rocks and Cretaceous-Paleogene granitoid rocks in SW Japan. The deep crust- and upper mantle-derived mafic to ultramafic xenoliths contained in Cenozoic volcanic rocks from SW Japan have comparable initial Sr and Nd isotope ratios to the Cretaceous-Paleogene granitoid rocks in their respective districts. This may suggest that these xenoliths were genetically related to the Cretaceous-Paleogene granitoid rocks in SW Japan, and that regional variations in Sr and Nd isotope ratios observed in the granitoid rocks are attributed to differences in the geochemistry of the magma sources.

    Full Text Available Poland in viewed by Ukraine as a reliable economic and political partner supporting Ukraine’s intention to integrate in Europe. Therefore, facts, documents and statistical data reflecting qualitative and quantitative aspects of relations between Ukraine and Poland need to be subject to non-stop monitoring and analysis, to help in finding timely solutions for problematic issues that may occur in these countries’ relations. The article’s objective is to analyze the performance and perspectives of economic and diplomatic relations between Ukraine and Republic of Poland. The analysis of documents on diplomatic and economic cooperation of the two countries after they gained political independence, and statistical data on trade in goods and services (by category and investment flows (by data on direct investment from Ukraine to Poland and from Poland to Ukraine shows that both countries have immense potentials for cooperation in various fields. As regards diplomatic dimension, Republic of Poland is the strongest promoter and lobbyist of the Euro-integration and Euro-Atlantic course of Ukraine. Regarding the economic cooperation, while mutual trade in goods declined in 2014 due to the economic and political crisis in Ukraine, it grew in 2016 with the recovery processes in the Ukrainian economy. Mutual trade in services is less intensive than trade in goods. Analysis of the investment cooperation shows the large asymmetry in favor of Polish investors in Ukraine and the reducing investment in both directions in the latest years.

  2. The Legionella pneumophila IcmSW complex interacts with multiple Dot/Icm effectors to facilitate type IV translocation.

    Directory of Open Access Journals (Sweden)

    Eric D Cambronne

    2007-12-01

    Full Text Available Many gram-negative pathogens use a type IV secretion system (T4SS to deliver effector proteins into eukaryotic host cells. The fidelity of protein translocation depends on the efficient recognition of effector proteins by the T4SS. Legionella pneumophila delivers a large number of effector proteins into eukaryotic cells using the Dot/Icm T4SS. How the Dot/Icm system is able to recognize and control the delivery of effectors is poorly understood. Recent studies suggest that the IcmS and IcmW proteins interact to form a stable complex that facilitates translocation of effector proteins by the Dot/Icm system by an unknown mechanism. Here we demonstrate that the IcmSW complex is necessary for the productive translocation of multiple Dot/Icm effector proteins. Effector proteins that were able to bind IcmSW in vitro required icmS and icmW for efficient translocation into eukaryotic cells during L. pneumophila infection. We identified regions in the effector protein SidG involved in icmSW-dependent translocation. Although the full-length SidG protein was translocated by an icmSW-dependent mechanism, deletion of amino terminal regions in the SidG protein resulted in icmSW-independent translocation, indicating that the IcmSW complex is not contributing directly to recognition of effector proteins by the Dot/Icm system. Biochemical and genetic studies showed that the IcmSW complex interacts with a central region of the SidG protein. The IcmSW interaction resulted in a conformational change in the SidG protein as determined by differences in protease sensitivity in vitro. These data suggest that IcmSW binding to effectors could enhance effector protein delivery by mediating a conformational change that facilitates T4SS recognition of a translocation domain located in the carboxyl region of the effector protein.

    We presented a general overview of the health care system as well as the pricing and reimbursement environment in Poland. Poland aims to ensure proper access to safe and effective medicines while reducing patients' share in treatment costs. Nevertheless, the co-payment for pharmacotherapy is still high (more than 60%). The key policymaker and regulator in the system is the Ministry of Health, which is supported by the Polish Agency for Health Technology Assessment and Tariff System (Agencja Oceny Technologii Medycznych i Taryfikacji), responsible for evaluating applicant drugs, and the Economic Commission, responsible for negotiating the official sales prices and conditions for reimbursement with pharmaceutical companies (e.g., level of reimbursement and risk-sharing scheme agreements). The Agency for Health Technology Assessment and Tariff System dossier is obligatory for reimbursement application and includes the analysis of clinical effectiveness, economic analysis (with the threshold of quality-adjusted life-year established as no more than 3 times the gross domestic product per capita), and the analysis of budget impact. In Poland, only a positive list of reimbursed drugs is published and it is updated every 2 months. The following levels of reimbursement are in use: 100%, 70%, 50%, and lump sum (about €0.8). The first reimbursement decision is given for a period of 2 years only, the second for 3 years, and the third for 5 years. There is no separate budget or special legal regulations for orphan drugs. Generic substitution of drugs is desired but not mandatory. Physicians are not assigned with pharmaceutical budgets. The access to real-world data is limited; the only registers available are for drugs used in drug programs. Copyright © 2017. Published by Elsevier Inc.

  4. Poland and Global Threats

    Kleer, Jerzy

    2016-01-01

    This essay seeks to present the specifics of global threats, as well as the reasons for them being universal in nature, and for their persistence. A certain classification of the threats is also engaged in. At the same time, an attempt is made to show the specific threats present - irrespective of their global counterparts - in different regions, and even in different states. The genesis and nature of the latter are demonstrated in a somewhat ad hoc manner by reference to the threats considered to face Poland. If the global threats are truly universal, and arise out of the changes taking place around the world in the last half-century (primarily around the twin phenomena of globalisation and the information revolution), a specific reverse kind of situation applies to decolonisation, plus the collapse of the communist system and the transformation into market economies that apply to formerly communist countries. Equally, some at least of the threats facing Poland may have even a longer history, given that they are very much influenced by past economic and political development, as well as the dominant cultural system.

  6. A subduction wedge origin for Paleoarchean peridotitic diamonds and harzburgites from the Panda kimberlite, Slave craton: evidence from Re-Os isotope systematics

    An extensive study of peridotitic sulfide inclusion bearing diamonds and their prospective harzburgitic host rocks from the 53 Ma Panda kimberlite pipe, Ekati Mine, NWT Canada, has been undertaken with the Re-Os system to establish their age and petrogenesis. Diamonds with peridotitic sulfide inclusions have poorly aggregated nitrogen (bearing diamonds and indicates residence in the cooler portion of the Slave craton lithospheric mantle. For most of the sulfide inclusions, relatively low Re contents (average 0.457 ppm) and high Os contents (average 339 ppm) lead to extremely low 187Re/188Os, typically << 0.05. An age of 3.52 ± 0.17 Ga (MSWD = 0.46) and a precise initial 187Os/188Os of 0.1093 ± 0.0001 are given by a single regression of 11 inclusions from five diamonds that individually provide coincident internal isochrons. This initial Os isotopic composition is 6% enriched in 187Os over 3.5 Ga chondritic or primitive mantle. Sulfide inclusions with less radiogenic initial Os isotopic compositions reflect isotopic heterogeneity in diamond forming fluids. The harzburgites have even lower initial 187Os/188Os than the sulfide inclusions, some approaching the isotopic composition of 3.5 Ga chondritic mantle. In several cases isotopically distinct sulfides occur in different growth zones of the same diamond. This supports a model where C-O-H-S fluids carrying a radiogenic Os signature were introduced into depleted harzburgite and produced diamonds containing sulfides conforming to the 3.5 Ga isochron. Reaction of this fluid with harzburgite led to diamonds with less radiogenic inclusions while elevating the Os isotope ratios of some harzburgites. Subduction is a viable way of introducing such fluids. This implies a role for subduction in creating early continental nuclei at 3.5 Ga and generating peridotitic diamonds.

  7. Trace element distribution in peridotite xenoliths from Tok, SE Siberian craton: A record of pervasive, multi-stage metasomatism in shallow refractory mantle

    2006-03-01

    Spinel peridotite xenoliths in alkali basalts at Tok, SE Siberian craton range from fertile lherzolites to harzburgites and wehrlites; olivine-rich (70-84%) rocks are dominant. REE patterns in the lherzolites range from nearly flat for fertile rocks (14-17% cpx) to LREE-enriched; the enrichments are positively correlated with modal olivine, consistent with high-permeability of olivine-rich rocks during melt percolation. Clinopyroxene in olivine-rich Tok peridotites typically has convex-upward trace element patterns (La/Nd PM 1); the LREE-enrichments are positively correlated with phosphorus abundances and are mainly hosted by accessory phosphates and P-rich cryptocrystalline materials. In addition to apatite, some Tok xenoliths contain whitlockite (an anhydrous, halogen-poor and Na-Mg-rich phosphate), which is common in meteorites and lunar rocks, but has not been reported from any terrestrial mantle samples. Some olivine-rich peridotites have generations of clinopyroxene with distinct abundances of Na, LREE, Sr and Zr. The mineralogical and trace element data indicate that the lithospheric mantle section represented by the xenoliths experienced a large-scale metasomatic event produced by upward migration of mafic silicate melts followed by percolation of low- T, alkali-rich melts and fluids. Chromatographic fractionation and fractional crystallisation of the melts close to the percolation front produced strong LREE-enrichments, which are most common in the uppermost mantle and are related to carbonate- and P 2O 5-rich derivatives of the initial melt. Reversal and gradual retreat of the percolation front during thermal relaxation to ambient geotherm ("retrograde" metasomatism) caused local migration and entrapment of small-volume residual fluids and precipitation of volatile-rich accessory minerals. A distinct metasomatic episode, which mainly produced "anhydrous" late-stage interstitial materials was concomitant with the alkali basaltic magmatism, which brought

    Ca isotopes are useful to decipher mantle evolution and the genetic relationship between the Earth and chondrites. It has been observed that Ca isotopes can be fractionated at high temperature [1-2]. However, Ca isotopic composition of the mantle peridotites and fractionation mechanism are still poorly constrained. Here, we report Ca isotope composition of 12 co-existing pyroxene pairs in 10 lherzolites, 1 harzburgite, and 1 wehrlite xenoliths collected from Hainan Island (South Eastern China). Ca isotope data were measured on a Triton-TIMS using the double spike method at the Guangzhou Institute of Geochemistry, CAS. The long-term external error is 0.12‰ (2SD) based on repeated analyses of NIST SRM 915a and geostandards. δ44Ca of clinopyroxenes except that from the wehrlite ranges from 0.85‰ to 1.14‰, while opx yields a wide range from 0.98‰ up to 2.16‰. Co-existing pyroxene pairs show large Δ44Caopx-cpx (defined as δ44Caopx-δ44Cacpx) ranging from 0 to 1.23‰, reflecting equilibrium fractionation controlled by variable Ca contents in the opx. Notably, clinopyroxene of wehrlite shows extremely high δ44Ca (3.22‰). δ44Ca of the bulk lherzolites and harzburgites range from 0.86‰ to 1.14‰. This can be explained by extracting melts with slightly light Ca isotopic compositions. Finally, the high δ44Ca of the wehrlite (3.22‰) may reflect metasomatism by melt which has preferentially lost light Ca isotopes due to chemical diffusion during upwelling through the melt channel.

    Poland was among the first Eastern European countries to apply for membership of the European Union. In view of Poland’s tragic history and the economic liberalisation that has taken place since 1989, we believe that the EU should adopt a generous approach toward its application. Unfortunately it looks as if the EU wants Poland to conform with all its laws before it can join. Our research suggests that the EU should pursue an open trade, labour and investment policy.

    2018-01-01

    Poland is one of the countries distinguished by a long and colorful past. Undergoing numerous turbulent socio-economic changes forced by the course of history, Poland is now one of the member states of the European Union. Experiencing low water quantity and high contamination levels in surface waters, Poland is following other EU countries in the effort to reach a "good" water status. Herein are presented impacts of changes in Polish history on water legislation, management, and research, as well as explanations for the perceptible split between engineering and scientific approaches to the aquatic issues. Drawbacks caused by unsatisfactory state research funding for the sciences and division of the water related contemporary scientific interests are also discussed.

    Full Text Available The paper summarizes main achievements, losses and gains during the first decade of Poland's membership in the EU, while also aiming at development of suggestions for the Polish economic policy in the years to come, as well as draws conclusions for Ukraine, which has now elected the strategy of international economic cooperation. The first part of the paper presents an empirical analysis of Poland's both real and technological convergence with the developed EU countries. These data show that since 1994, as the process of Poland integration with the EU commenced, our country significantly reduced the income and technology gap as compared to the EU. During the financial crisis, Poland 'felt' better than most European countries. In the second part of the paper we attempt to answer the question as to the current conditions of Polish economy development. It is demonstrated that Poland's economic success was due to multiple factors such as endogenous and exogenous, historical and those derived from present events. However, it can be assumed that integration with the EU has been an important positive factor in development of Poland during recent 20 years. Great importance was also vested in the implementation of economic reforms in Poland as well as in policy of the government, although not faultless. The last section of the paper identifies problems now faced by the EU and individual member states, including Poland as regards future years till 2020

    2004-12-01

    In 1997, a new Energy Law was passed in Poland. An important element of the law is that local energy planning is made obligatory. The law describes obligatory tasks and procedures for Polish municipalities related to planning and organisation of the energy sector. With the objective of supporting the Polish municipalities in their obligations according to the energy law of 1997, the project 'Energy Planning in Poland at Municipal Level - Support to Decision Makers' was launched. As part of the project, Municipal Guideline Reports have been elaborated for three model municipalities. These guidelines present the basis for the Energy Supply Plans in these municipalities. For the city of Legionowo, the following was recommended: 1. The planning processes initiated during the project should be continues/followed up, 2. Master Plan for the district heating system should be prepared, 3. The possibilities of establishment of a major natural gas-fired CHP plant of the Combined Cycle type should be investigated. The present report is the final Master Plan based on the following reports: Master Plan for Legionowo - Status Report; Master Plan for Legionowo - Hydraulic Analysis; CHP Plant Legionowo Poland - CHP Feasibility Analysis. The final Master Plan describes the status in the DH Company in Legionowo, possible improvements and an investment plan for the selected scenario. (BA)

    Full Text Available Strong global warming has been observed in the last three decades. Central Europe, including Poland, is not an exception. Moreover, climate projections for Poland foresee further warming as well as changes in the spatial and seasonal distribution and quantity of precipitation. However, climate models do not agree on the sign of change of precipitation. In Poland precipitation is projected to decrease in summer (this finding is not robust, being model-dependent and to increase in winter. Therefore, there is still considerable uncertainty regarding likely climate change impacts on water resources in Poland. However, there is no doubt that changes in the thermal characteristics as well as in precipitation will influence changes in the water balance of the country. In this study, the components of climatic water balance, that is, precipitation, evaporation, and runoff, are calculated for the average conditions in the control period of 1961–1990 and in the future (2071–2100 in Poland. The changes of the water balance components for the present and for the future are compared and analysed. Due to insufficient consistency between climate models a possible range of changes should be presented; hence the multimodel projections from ENSEMBLES Project of the European Union are used in this study.

  14. Unravelling the role of SW Sextantis stars in the evolution of cataclysmic variables

    2005-08-01

    SW Sextantis stars are a relatively large group of cataclysmic variables whose properties contradict all predictions made by the current CV evolution theories. Very little is known about the properties of their accreting white dwarfs and their donor stars, as the stellar components are usually outshone by an extremely bright accretion flow. Consequently, a proper assessment of their evolutionary state is illusionary. There is one particular behavior of the SW Sex stars that can allow us to overcome this problem: SW Sex stars exhibit low states during which accretion onto the white dwarf decreases or shuts off completely. Only during this rare occasions we can directly observe the white dwarf and the donor star in these systems, and measurements of the white dwarf temperature, spectral type of the donor, mass and distance to the system can be carried out. With this aim in mind, we have set up a long-term monitoring of a group of five SW Sex stars using the 1.3 m telescope at CTIO. Here we propose to activate follow-up TOOs to obtain optical spectra of the low states to accurately determine the fundamental properties of these systems.

    Poland started the works on construction of first nuclear power plant in 1992. The social protest as well as deep political and economical changes in Poland induced the decision of the Polish government to abandon the construction of the nuclear power plant in Zarnowiec. After the period of political and economical transformation, in 1992 Polish economy starts to grow up, also growth of the electric power consumption. Are there prospect for utilization in Poland the nuclear power plant? This work is devoted to analyse such question. The present structure of power and fuel materials in Poland were analysed and the possible direction of changes was shown for the period up to 2020 year. It was stated, that the economical development in Poland should be bound with the growth of the consumption of most effective fuel and energy. These fuel or energy should be imported to Poland. Therefore, the nuclear power should be treated as one of possible ways of the balance of electric power in Poland. Particularly, that it will be expected the special ecological conditions in the energy production in Europe. In the present work, was shown, that the nuclear power was discriminated in the analysis of the development of power and fuel system in Poland. The incorrect values of economical parameters concerning of the nuclear power plant was used in the analysing numerical programs. The investment costs, design time and fuel price for nuclear energy was analysed, and shown, that in the proper conditions, the cost of the electric energy produced in the nuclear power plant is compared with the costs of electric energy produced in the conventional power stations. In this work, the proposals of the basic nuclear and radiological safety standards for the nuclear power plant in Poland are shown. (author). 20 refs, 10 figs, 3 tabs.

  18. The formation of lipid droplets favors intracellular Mycobacterium leprae survival in SW-10, non-myelinating Schwann cells.

    Leprosy is a chronic infectious disease that is caused by the obligate intracellular pathogen Mycobacterium leprae (M.leprae), which is the leading cause of all non-traumatic peripheral neuropathies worldwide. Although both myelinating and non-myelinating Schwann cells are infected by M.leprae in patients with lepromatous leprosy, M.leprae preferentially invades the non-myelinating Schwann cells. However, the effect of M.leprae infection on non-myelinating Schwann cells has not been elucidated. Lipid droplets (LDs) are found in M.leprae-infected Schwann cells in the nerve biopsies of lepromatous leprosy patients. M.leprae-induced LD formation favors intracellular M.leprae survival in primary Schwann cells and in a myelinating Schwann cell line referred to as ST88-14. In the current study, we initially characterized SW-10 cells and investigated the effects of LDs on M.leprae-infected SW-10 cells, which are non-myelinating Schwann cells. SW-10 cells express S100, a marker for cells from the neural crest, and NGFR p75, a marker for immature or non-myelinating Schwann cells. SW-10 cells, however, do not express myelin basic protein (MBP), a marker for myelinating Schwann cells, and myelin protein zero (MPZ), a marker for precursor, immature, or myelinating Schwann cells, all of which suggests that SW-10 cells are non-myelinating Schwann cells. In addition, SW-10 cells have phagocytic activity and can be infected with M. leprae. Infection with M. leprae induces the formation of LDs. Furthermore, inhibiting the formation of M. leprae-induced LD enhances the maturation of phagosomes containing live M.leprae and decreases the ATP content in the M. leprae found in SW-10 cells. These facts suggest that LD formation by M. leprae favors intracellular M. leprae survival in SW-10 cells, which leads to the logical conclusion that M.leprae-infected SW-10 cells can be a new model for investigating the interaction of M.leprae with non-myelinating Schwann cells.

    In Poland in 2007 there were 11 malaria cases confirmed according to the European Union cases definition reported through the routine surveillance system. All of them were imported, 82% from Africa, including 2 cases of relapse. Invasion with Plasmodium falciparum was diagnosed in 7 cases, mixed invasion in 2 cases and P. vivax- in one case. The majority of cases were in the age group 35-45 (8 cases) and were males (10 cases). Common reasons for travel to endemic countries were work-related (5 cases) and tourism or family visits (4 cases). Approximately half of the cases for whom the information was available used malaria chemoprophylaxis during their travel. Clinical course was severe in one case of P. falciparum malaria and the person died of the disease. The decreasing trend in malaria incidence in Poland is likely related to incomplete reporting as tourist and professional travel to endemic areas has not decreased and there is no indication of wider use ofchemoprophylaxis.

    The application of zircon and xenotime geochronometers requires knowledge of their potential and limitations related to possible disturbance of the age record. The alteration of the intergrown zircon and xenotime in pegmatite from the Góry Sowie Block (SW Poland) was studied using the electron microprobe analysis, X-ray WDS compositional mapping, micro-Raman analysis, and LA-ICP-MS U-Pb dating of zircon and xenotime, as well as the U-Th-total Pb dating of uraninite. These microanalytical techniques were applied to understand the formation mechanisms of the secondary textures related to post-magmatic processes in the zircon and xenotime intergrowth, and to constrain their timing. Textural and compositional features combined with U-Pb data indicate that the pegmatite-related crystallization of the zircon and xenotime intergrowth occurred ca. 2.09 Ga (2086 ± 35 Ma for zircon and 2093 ± 52 Ma for xenotime), followed by the re-equilibration of zircon and xenotime ca. 370 Ma (373 ± 18 Ma and 368 ± 6 Ma, respectively) during the formation of the younger pegmatite. The zircon and xenotime were most likely derived from Precambrian basement rocks and emplaced in the pegmatite as a restite. The zircon preserved textures related to diffusion-reaction processes that affected its high-U core (up to ca. 9.6 wt% UO2), which underwent further metamictization and amorphization due to self-radiation damage. The zircon rim and xenotime were affected by coupled dissolution-reprecipitation processes that resulted in patchy zoning, age disturbance and sponge-like textures. Xenotime was also partially replaced by fluorapatite or hingganite-(Y) and Y-enriched allanite-(Ce). The termination of the low-temperature alteration was constrained by the U-Th-total Pb age of the uraninite inclusions that crystallized in zircon at 281 ± 2 Ma, which is consistent with the age of 278 ± 15 Ma obtained from the youngest cluster of U-Pb ages in the re-equilibrated high-U zircon domains.

    Statistical analysis of the daily course of exposures to TL-01 tube radiation for 93 psoriatic patients from the Medical University of Łódź during 20-day phototherapy shows that the dose of 1 J/cm(2) represents a unit of single exposure necessary for psoriasis healing. This value is converted to the antipsoriatic effective dose of 317.9 J/m(2) using the TL-01 lamp irradiance spectrum and the antipsoriatic action spectrum. It is proposed that the daily exposure of 317.9 J/m(2) serves as the standard antipsoriatic dose (SAPD) providing a link between the cabinet and the out-door exposures and it could be used for planning heliotherapy in Poland. A model is proposed to calculate ambient antipsoriatic doses for 3 h exposures around the local noon (9 am-12 am GMT) based on satellite measurements of ozone and cloud characteristics. The model constants are determined by a comparison with pertaining antipsoriatic doses measured by the Brewer spectrophotometer in central Poland. It is found that 3 h exposures to solar radiation in the period 15 May-15 September provides the mean (2005-2013) doses in the range 2.7-3.1 SAPD over Poland. Thus, heliotherapy could be treated as an alternative to the cabinet phototherapy for almost 4 months. It seems that the most effective site for antipsoriatic heliotherapy is the south/east part of Poland (the Bieszczady Mountains). The heliotherapy could be carried out in existing national health centers equipped with the standard easy-to-use biometers for on-line monitoring of UV level and controlling duration of sunbathing to avoid erythema risks. It is even possible to control the antipsoriatic heliotherapy by a patient himself, using low-cost hand-held instruments measuring UV index. Copyright © 2014 Elsevier B.V. All rights reserved.

    Poland’s plan for reorganization of its energy mix is to construct several nuclear reactors (2 NPPs with number of units depending on reactor type) of total capacity 6000 MW. It is assumed that energy from NPPs will provide up to 19% of the electricity production in Poland after 2035. Currently there is no nuclear power plant in operation. The previous nuclear programme was canceled in 1990. Almost 20 years later Polish government has undertaken second attempt to construct first NPP by adoption of The Polish Nuclear Power Program in January 2014. Since that moment were started intensive preparations to implement many legal regulations related to future nuclear industry in Poland e.g. Atomic Law amendment. In the same year the Owner’s Engineer was chosen by the main investor PGE S.A. Following “nuclear” a lot of Polish Universities launched studies connected with the subject to ensure employees for deployment and sustaining of nuclear technologies in Poland. This paper describes the rationale staying behind the government decision, present situation of Polish energy market and current work status. (Author)

  8. High energy physics in Poland: the first 50 years

    International Nuclear Information System (INIS)

    1993-01-01

    High energy physics in Poland started in 1933 when Stanislaw Ziemecki and Konstanty Narkiewicz-Jodko performed measurements of the latitude effect for cosmic rays. Subsequently, experiments with cosmic rays were carried out in balloon flights in a deep salt mine. Other Polish pioneers in this field were Ignacy Adamczewski, Czeslaw Bialobrzeski, Marian Miesowicz, Szczepan Szczeniowski and Jan Wesolowski. The ambitious 'Star of Poland' project of a stratospheric balloon flight to study cosmic rays up to an altitude of 30000 meters was not successful, first because of the fire accident and then of the outbreak of World War II. The destruction of laboratories during the war has slowed down the development of high energy physics in Poland by at least twelve years. However, in the late forties Marian Miesowicz started important cosmic ray studies in Cracow. In 1952 research using nuclear emulsions was initiated in Warsaw by Marian Danysz and Jerzy Pniewski. Two years later Marian Miesowicz and Jerzy Gierula began similar research in Cracow. In the late fifties Aleksander Zawadzki in Lodz started comprehensive studies of extensive air showers. Already in 1963 the number of experimental and theoretical papers on high energy physics published in Poland exceeded 100. Strong experimental and theoretical groups have been established in Cracow, Lodz and Warsaw. To supplement research with emulsions and bubble chambers the construction of electronic detectors for on-line experiments has been instituted. Thus, in the early eighties Polish high energy physicists were ready to participate in large projects such as DELPHI at LEP and ZEUS and H1 at HERA. The discovery of hypernuclei by Danysz and Pniewski in 1952 may be regarded as the most important achievement of physics in post-war Poland. (author). 108 refs, 26 figs, 1 tab

    Both the Czech Republic and Poland as former Communist countries, are transforming their economies from central planning to a free market. This applies equally to energy planning and because they are starting from the same point, they have come up with very comparable solutions despite strong cultural differences, so that the parallels are striking. This study analyzes the energy management in local authorities in Poland and the Czech Republic with the objective of better: identifying the current situation, identifying the opportunities for action both now and in an extended European Union, identifying the constraints that may hinder full integration of East European municipalities in European Union programmes, improve the integration of municipalities in the countries concerned in pan-European networks of municipalities interested in energy issues. The study reviews the powers and responsibilities of local authorities in the energy field and the institutional framework within which local authorities work. There are now 16 directly elected regional authorities in Poland and the local authorities have been restructured into two levels, the Powiad and the Gmina. Similarly, in the Czech Republic 14 elected regional authorities have been established. This document brings together 2 reports: the final report and the study report about the energy policies in Poland and in the Czech republic: structure of local government, general and institutional aspects, national political organisation, national administrative organisation, municipal role in production and distribution, regulation and planning, energy issues, energy management policies, specific aspects at local level etc... The conclusions from two review seminars (Jablonec nad Nison (Czech republic), 25-26 January 2001, and Bielsko Biala (Poland), 22-23 February 2001) and some fact files on 4 large Czech towns and 4 large Polish towns complete the study.

    The objective of this study is to illustrate and provide a better understanding of the role of health technology assessment (HTA) processes in decision making for drug reimbursement in Poland and how this approach could be considered by other countries of limited resources. We analyzed the evolution of the HTA system and processes in Poland over the past decade and current developments based on publicly available information. The role of HTA in drug-reimbursement process in Poland has increased substantially over the recent decade, starting in 2005 with the formation the Agency for Health Technology Assessment and Tariff System (AOTMiT). The key success factors in this development were effective capacity building based on the use of international expertise, the implementation of transparent criteria into the drug reimbursement processes, and the selective approach to the adoption of innovative medicines based on the cost-effectiveness threshold among other criteria. While Poland is regarded as a leader in Central and Eastern Europe, there is room for improvement, especially with regard to the quality of HTA processes and the consistency of HTA guidelines with reimbursement law. In the "pragmatic" HTA model use by AOTMiT, the pharmaceutical company is responsible for the preparation of a reimbursement dossier of good quality in line with HTA guidelines while the assessment team in AOTMiT is responsible for critical review of that dossier. Adoption of this model may be considered by other countries with limited resources to balance differing priorities and ensure transparent and objective access to medicines for patients who need them.

    The Ortsog-Uul mafic-ultramafic massif of Western Mongolia is located in a tectonic block with overturned bedding. The massif hosts two intrusions: a rhythmically-layered peridotite-gabbro association (Intrusion 1) and massive Bt-bearing amphibole-olivine gabbro (Intrusion 2). Intrusions 1 and 2 have different petrology features. Early Intrusion 1 (278±2.5Ma) is characterized by lower concentrations of alkalis, titanium and phosphorus than late Intrusion 2 (272±2Ma). The chondrite-normalized REE and primitive mantle-normalized rare elements patterns of Ortsog-Uul intrusions have similar curves of elements distribution. However, Intrusion 2 is characterized higher contents of REE and rare elements. High concentrations of incompatible elements are indicative of strong fractionation process. It has been suggested that Intrusions 1 and 2 derived from compositionally different parental melts. Model calculations (COMAGMAT-3.57) show that parental melts of two intrusions were close to high-Mg picrobasaltic magmas. The concentration of MgO in melt is 16.21 (Intrusion 1) and 16.17 (Intrusion 2). Isotopic data of Ortsog-Uul magmatic rocks exhibit different values of εNd (positive and negative) for Intrusion 1 and 2, respectively.

    2014-01-01

    Full Text Available The mycorrhizal status of two plant communities representing an initial stage (1-2 year-old and a 8-9-year-old stage of succession on spoil heaps from fireloam mining in Lower Silesia, Poland, was determined. In the initial stage, the mycorrhizal structures were not observed in 39% of the investigated species; they were members of the Polygonaceae, Chenopodiaceae and Poaceae families. The relative cover of non-mycorrhizal plants exceeded 50% and the major role was played by the Polygonum aviculare population, which predominated the whole community. Mycorrhizal species (arbuscular mycorrhizae contributed to 61 % of the composition of the initial phyto-coenosis. The most numerous taxa were those with 20-40% of the root length colonized, with a small number of arbuscules (0.2-3.1% of the root length containig arbuscules and no vesicles. In the advanced stage of succession, mycorrhizal plants definitely dominated and the major role was played by the Tussilago farfara population. Compared with the initial stage, the later one also harboured more plants with mycorrhizas occupied >40% of the root length, as well as containing numerous arbuscules (>20% of the root length and vesicles. The non-mycorrhizal species, i.e., Equisetum arvense and Poa compressa, represented 11 % o': the community composition and their relative cover amounted to 3%. Despite the relatively frequent occurrence of the arbuscular mycorrhizae in the initial stage of succession, the qualitative properties of the colonization indicated a low effectiveness of symbiosis. This could be caused by the lack of adaptation of the fungal symbiont to the edaphic conditions which were changed after disturbance.

  17. Lignite mining and electricity generation in Poland: The current state and future prospects

    2016-01-01

    This opinion paper presents the current state and future scenarios of Polish lignite mining. For many years, over 1/3 of domestic electricity, that is about 53–55 TWh, has been generated by lignite-fired power plants. Currently, with 63–66 million tons of extraction, Poland is the fourth lignite producer worldwide and the second in the European Union. There are three possible scenarios for the development of lignite mining in Poland by 2050. Unfortunately, despite the huge lignite resources, amounting to more than 23.5 billion tons, and great potential of the mining industry, the future of Polish lignite mining does not look optimistic from the economic point of view. This is associated with social and environmental problems, including the European Union's climate and energy policy. However, this may change in the event of a global economic crisis and unstable geopolitical conditions. Therefore, a new energy doctrine for Poland at least by 2050 is urgently needed. - Highlights: •Poland is one of the leaders in lignite production in the European Union. •Energy policy in Poland assumes a key role of lignite in energy mix. •Almost one-third of Polish electricity is currently generated from lignite. •For Polish lignite mining exist pessimistic, realistic and optimistic scenarios. •Extraction of lignite in Poland will gradually decrease in the coming decades.

  18. The unwanted heroes: war invalids in Poland after World War I.

    This article focuses on the unique and hitherto unknown history of disabled ex-servicemen and civilians in interwar Poland. In 1914, thousands of Poles were conscripted into the Austrian, Prussian, and Russian armies and forced to fight against each other. When the war ended and Poland regained independence after more than one hundred years of partition, the fledgling government was unable to provide support for the more than three hundred thousand disabled war victims, not to mention the many civilians left injured or orphaned by the war. The vast majority of these victims were ex-servicemen of foreign armies, and were deprived of any war compensation. Neither the Polish government nor the impoverished society could meet the disabled ex-servicemen's medical and material needs; therefore, these men had to take responsibility for themselves and started cooperatives and war-invalids-owned enterprises. A social collaboration between Poland and America, rare in Europe at that time, was initiated by the Polish community in the United States to help blind ex-servicemen in Poland.

    2017-08-01

    Full Text Available Based on published literature, at least eighty species of stygobiontic invertebrates are confirmed in Poland. The highest number of these species is found in interstitial waters and wells, while a lower number was discovered in caves and springs. Hydrachnidia is represented by 45 species living mainly in interstitial waters, Crustacea by 24, Annelida by eleven species, while Turbellaria and Gastropoda are each represented by one species. As many as 14 endemic species were described from Poland but the taxonomical status of some of them is unclear. The highest number of stygobionts was stated in southern part of Poland, an area onto which most of the studies were focused on.

    Formation conditions of olivine microstructures are investigated in the Kittelfjäll spinel peridotite (KSP), a fragment of lithospheric mantle which occurs as an isolated body within high grade metamorphic crustal rocks of the Seve Nappe Complex (SNC), southern Västerbotten, central Sweden. The KSP is an orogenic peridotite containing a well developed penetrative compositional layering, defined by highly depleted dunite with olivine Mg# (100 × Mg/Mg + Fe) of 92.0-93.5 and harzburgite with lower Mg# (91.0-92.5). Dunite is characterized by three contrasting olivine microstructures formed in response to different tectonometamorphic events: Coarse-grained, highly strained olivine porphyroclasts (M1) up to 20 cm long are surrounded by dynamically recrystallized olivine grains (M2) defining a characteristic olivine "foam" microstructure (grain size: 200-2000 μm). An olivine "mortar" (M3) microstructure (10-50 μm) forms a penetrative fabric element only in strongly localized, cm-to-m sized shear zones that crosscut earlier structures/foliations. Olivine fabric analysis in synergy, with mineralogical and chemical analyses, reveals that the KSP body represents old, possibly Archean, sub-continental lithospheric mantle that was crustally emplaced into the Caledonian tectonic edifice from the hanging wall mantle during exhumation of the subducted Seve Nappe Complex (Jämtlandian orogeny ~ 454 Ma). Olivine porphyroclasts (M1) grew at high temperature during dominant isobaric cooling after extensive polybaric melt extraction (> 40%) and subsequent refertilization. The onset of the early Caledonian deformation is interpreted to be related to the crustal emplacement of the KSP during eduction of the SNC. This phase is characterized by the development of the olivine M2 foam microstructure, formed at 650-830 °C/1-2 GPa by dislocation creep processes producing an E-type CPO's by the operation of the [100](001) and subordinate [001](100) slip systems with operating flow stress

    1999-01-01

    The issue of radioactive contaminated metallurgical scrap has never received a high priority in Poland and in the international community. Since the dissolution of the former Soviet Union a higher attention has been given to the problem. Poland which is located between the West and East Europe has the obligation to develop and implement an effective prevention and detection system. The reasons to increase national control and detection system at the border checkpoints in Poland are to avoid the following risks: post Chernobyl contamination transports of commodities; transport of contaminated metal scrap; transfer of radioactive waste for their disposal or utilization; high risk of becoming a transit country of illicit trafficking of nuclear materials and radioactive sources. In order to avoid the above-mentioned risks, Poland initiated in 1990, a deployment of the portable radiation devices at the border checkpoints and, as of 1998, the number of installed instruments exceeded a hundred. This paper presents Poland's activities to detect contaminated scrap at its border checkpoints. (author)

    2001-12-01

    Full Text Available Poland belongs to one of the last countries with native sulphur mining. Its history begun in 15th century. Deposit area of Tarnobrzeg re-presents 80% of all known sulphur reserves in this country. All of explored deposits in this area were created by metasomatic alteration of sulphur bearing limestones with sulphur mineralised liquids, which arised from melt gypsum. The average content is 25 - 30% of sulphur in Tarnobrzeg area. Considerable parts of deposits are created by calcite and native sulphur. Gypstone, baryte and stroncianite have only minera-logic occurencies. The extensive native sulphur deposits account for 88% of the country´s sulphur production. There were five sulphur mines in operation: Jeziórko, Grêbów, Machów I, Machów II and Basznia, but operations in Basznia were ended in 1992 and Machów and Machów II were liquidated. The sixth mine Osiek is currently producing. Only the Machów I mine operated an open-pit extraction and refining process, the other four mines producing sulphur using a modified Frasch method that gives elemental sulphur of up to 99,9% purity. Sulphur is an important export commodity with foreign sales totalling around 1.5 - 2.5 Mt/y. Modern benefication methods, which allowing to achieve sulphur from hydrocarbons, are causing decrease of native sulphur prices in the world and bringing about reduction of mining activities for this raw material in Poland.

  6. Cloud effects on the SW radiation at the surface at a mid-latitude site in southwestern Europe

    2017-04-01

    This work presents a study of cloud radiative effects on shortwave (CRESW) radiation at the surface in Évora region (southwestern Europe) during 2015 and a case study is analyzed. CRESW (in Wm-2) is defined as the difference between the net shortwave irradiance (downward minus upward shortwave irradiance) in cloudy and clear sky conditions. This measure is usually used to translate changes in the SW radiation that reaches the surface due to changes in clouds (type and/or cover). The CRESW is obtained using measured SW irradiance recorded with a Kipp&Zonen CM 6B pyranometer (broadband 305 - 2800 nm) during the period from January to December 2015, and is related with the cloud liquid water path (LWP) and with cloud ice water path (IWP) showing the importance of the different type of clouds in attenuating the SW radiation at the surface. The cloud modification factor, also a measure of the cloud radiative effects (CMF; ratio between the measured SW irradiance under cloudy conditions and the estimated SW irradiance in clear-sky conditions) is related with the cloud optical thickness (COT; obtained from satellite data). This relation between CMF and COT is shown for different cloud fractions revealing an exponential decreasing of CMF as COT increases. Reductions in the SW radiation of the order of 80% (CMF = 0.2) as well enhancements in the SW radiation larger than 30% (CMF = 1.3) were found for small COT values and for different cloud fractions. A case study to analyse the enhancement events in a cloudy day was considered and the cloud properties, COT and LWP (from satellite and surface measurements), were related with the CRESW.

    1965-04-01

    In the past few years medical education in Poland has undergone considerable change, particularly at the graduate and postgraduate levels, and has shown increasing Western influences. On the negative side, a physician who was trained in pre-war Poland and is now in the United States, noted mass production of physicians with modest clinical facilities and the preponderance of didactic lecturing over semi-individual instruction-conditions rather characteristic of most European medical schools. On the positive side were well-informed, up-to-date faculties and the thoughtful planning and organization of graduate and postgraduate medical education. The overall impression was a favorable one, but the system of schooling and of evaluation of students' work made it possible for indifferent students to progress to licensure.

Link] reported in Poland has been studied. Currently, V. myuros and especially V. bromoides are very rare species, and their greatest concentration can be found only in the Lower Silesia region. The number of their localities decreased after 1950 and it seems resonable to include both species in the "red list" of threatened plants in Poland: V. myuros in the EN category, V. bromoides in the CR category. V. ciliata and V. geniculata are very rare ephemerophytes and their localities not confirmed during ca 60 years are of historical interest only.

    2016-09-01

    Full Text Available The paper includes analysis and assessment of trade in the ICT services performance of Poland. This study is looked at the trade position, essentially on the basis of the share in the world ICT services exports, revealed comparative advantage (RCA, and trade coverage ratio. It also identifies trends of the world trade in the ICT services. The statistics are derived from the basis of UNCTAD and Eurostat. International trade in the ICT ser-vices sector has specific characteristics and the interpretation of results of this trade is to take account of the particular nature of the ICT services. Poland is currently not revealed comparative advantage in the ICT services exports, but has had positive balance. Practically all trade indicators for Poland show very strong growth, which indicate a significant improvement in its ICT services trade position.

    In Poland in 2009 were reported 22 malaria cases confirmed according to the EU case definition for the purposes of routine surveillance system. All of them were imported, including 1 case of recrudescence, 86% from Africa. In 18 cases P falciparum etiology was confirmed and in 2--P vivax, in 1--P ovale and 1 P malariae. Most cases occurred in the age group 21-40 years, there were 21 cases in males and 1 in female. Common reasons for travel to endemic countries were work-related visits (14 cases) and tourism (6 cases), one person who visited the family and in one case unknown reason for travel. Three persons used chemoprophylaxis during their travel but only one of them appropriately, relevant information was missing in 5 cases. Clinical course was severe in 7 cases of P falciparum malaria and medium-severe in one case. In 2009, there were no malaria deaths in Poland. Education on the prevention of malaria and pretravel health advising is still greatly needed.

  12. Pavement noise measurements in Poland

    2017-09-01

    The objective of this study is to investigate the feasibility of the On-Board Sound Intensity (OBSI) system to measure tire-pavement noise in Poland. In general, sources of noise emitted by the modern vehicles are the propulsion noise, aerodynamic resistance and noise generated at the tire-pavement interface. In order to capture tire-pavement noise, the OBSI system uses a noise intensity probe installed in the close proximity of that interface. In this study, OBSI measurements were performed at different types of pavement surfaces such as stone mastic asphalt (SMA), regular asphalt concrete (HMA) as well as Portland cement concrete (PCC). The influence of several necessary OBSI measurement conditions were recognized as: testing speed, air temperature, tire pressure and tire type. The results of this study demonstrate that the OBSI system is a viable and robust tool that can be used for the quality evaluation of newly built asphalt pavements in Poland. It can be also applied to generate reliable input parameters for the noise propagation models that are used to assess the environmental impact of new and existing highway corridors.

    2018-01-01

    Full Text Available The study presents the temporal and spatial variability of particulate matter concentration in Poland in the calendar winter season (December-February. The basis for the study were the hourly and daily values of particulate matter PM10 concentration from the period 2005/06 – 2014/15, obtained from 33 air pollution monitoring stations. In Poland, the obligation to monitor the concentration of the finer fraction of particles smaller than 2.5µm in aerodynamic diameter was introduced only in 2010. Consequently, data on PM2.5 concentration refer to a shorter period, i.e. 2009/10 – 2014/15, and were obtained from 23 stations. Using the cluster analysis (k-means method, three regions of comparable variability of particulate matter concentration were delineated. The largest region, i.e. Region I, comprises the northern and eastern central area of Poland, and its southern boundary is along the line Gorzów Wlkp-Bydgoszcz-Konin-Łódź-Kielce-Lublin. Markedly smaller Region II is located to the south of Region I. By far the smallest area was designated to Region III which covers the south west area of Poland. The delineated regions show a marked variability in terms of mean concentration of both PM fractions in winter (PM10: region I - 33 µg·m-3, region II - 55 µg·m-3, region III - 83 µg·m-3; PM2,5: region I - 35 µg·m-3, region II - 50 µg·m-3, region III - 60 µg·m-3 and, in the case of PM10, the frequency of excessive daily limit value.

    The study presents the temporal and spatial variability of particulate matter concentration in Poland in the calendar winter season (December-February). The basis for the study were the hourly and daily values of particulate matter PM10 concentration from the period 2005/06 - 2014/15, obtained from 33 air pollution monitoring stations. In Poland, the obligation to monitor the concentration of the finer fraction of particles smaller than 2.5µm in aerodynamic diameter was introduced only in 2010. Consequently, data on PM2.5 concentration refer to a shorter period, i.e. 2009/10 - 2014/15, and were obtained from 23 stations. Using the cluster analysis (k-means method), three regions of comparable variability of particulate matter concentration were delineated. The largest region, i.e. Region I, comprises the northern and eastern central area of Poland, and its southern boundary is along the line Gorzów Wlkp-Bydgoszcz-Konin-Łódź-Kielce-Lublin. Markedly smaller Region II is located to the south of Region I. By far the smallest area was designated to Region III which covers the south west area of Poland. The delineated regions show a marked variability in terms of mean concentration of both PM fractions in winter (PM10: region I - 33 µg·m-3, region II - 55 µg·m-3, region III - 83 µg·m-3; PM2,5: region I - 35 µg·m-3, region II - 50 µg·m-3, region III - 60 µg·m-3) and, in the case of PM10, the frequency of excessive daily limit value.

    Concentration of the metals Al, Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, Sr, Zn and V as well as N, P, K, Ca, Mg, Fe and S were measured in soils and in two tree species (leaves of Betula pendula and Salix caprea) and two herbs (whole above-ground parts of Solidago canadensis and Tanacetum vulgare) sampled from dumps in the Walbrzych coal mine area (Lower Silesia, SW Poland). These plants, as used to evaluate the distribution of elements in the examined dumps, contained elevated levels of Cd, Co, Cu, Mn, Ni, Pb and Zn. Especially the highest levels of Mn in Betula pendula seriously exceed background values. Betula pendula characterized also the highest enrichment ratio for Mn, Salix caprea for Ni and Sr and Tanacetum vulgare for Cu. Test-t indicated that from both herbs Tanace-tum vulgare accumulated much more K, N, S and Zn than Solidago canadensis and of both trees Salix caprea accumulated significantly more Cd, Cu, K and Ca than Betula pendula, while this last species accumulated significantly more Fe and Mn than Salix caprea. A post hoc LSD test indicated that all examined plants had similar enrichment ratios for Al, Pb and V.

    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...

    In many machine learning applications, like brain-computer interfaces (BCI), high-dimensional sensor array data are available. Sensor measurements are often highly correlated and signal-to-noise ratio is not homogeneously spread across sensors. Thus, collected data are highly variable and discrimination tasks are challenging. In this work, we focus on sensor weighting as an efficient tool to improve the classification procedure. We present an approach integrating sensor weighting in the classification framework. Sensor weights are considered as hyper-parameters to be learned by a support vector machine (SVM). The resulting sensor weighting SVM (sw-SVM) is designed to satisfy a margin criterion, that is, the generalization error. Experimental studies on two data sets are presented, a P300 data set and an error-related potential (ErrP) data set. For the P300 data set (BCI competition III), for which a large number of trials is available, the sw-SVM proves to perform equivalently with respect to the ensemble SVM strategy that won the competition. For the ErrP data set, for which a small number of trials are available, the sw-SVM shows superior performances as compared to three state-of-the art approaches. Results suggest that the sw-SVM promises to be useful in event-related potentials classification, even with a small number of training trials.

    2011-09-01

    Full Text Available Abstract Introduction Poland syndrome is a congenital disorder related to chest and hand anomalies on one side of the body. Its etiology remains unclear, with an ipsilateral vascular alteration (of unknown origin to the subclavian artery in early embryogenesis being the currently accepted theory. Cavernous malformations are vascular hamartomas, which have been linked to a genetic etiology, particularly in familial cases, which commonly present with multiple lesions. Our case report is the first to describe multiple cavernous malformations associated with Poland syndrome, further supporting the vascular etiology theory, but pointing to a genetic rather than a mechanistic factor disrupting blood flow in the corresponding vessels. Case presentation A 41-year-old Caucasian man with Poland syndrome on the right side of his body presented to our hospital with a secondary generalized seizure and was found to have multiple cavernous malformations distributed in his brain, cerebellum, and brain stem, with a predominance of lesions in the left hemisphere. Conclusion The distribution of cavernous malformations in the left hemisphere and the right-sided Poland syndrome in our patient could not be explained by a mechanistic disruption of one of the subclavian arteries. A genetic alteration, as in familial cavernous malformations, would be a more appropriate etiologic diagnosis of Poland syndrome in our patient. Further genetic and pathological studies of the involved blood vessels in patients with Poland syndrome could lead to a better understanding of the disease.

    Full Text Available The paper presents the results of studies of Xanthoparmelia pulla group in Poland. The morphological and chemical analysis of herbarium materials confirmed the presence of four species of this group reported from Poland before. The study however, revealed considerable changes it the partiuclular species distribution. X. verruculifera, so far considered the most endangered species in the country, turned out to be the most frequent taxon. X. loxodes, regarded as common, has much less known localities than previously thought. This species was usually confused with X. verruculifera. Xanthoparmelia pulla is the rarest species and should be considered critically endangered in Poland. Most specimens of X. pulla collected in the country belong to X. delisei, which so far had only two historical records in Poland. All these taxa are characterized in terms of morphology, the content of secondary metabolites, ecology and distribution.

    1997-01-01

    The National System of Sickness Absenteeism Statistics has been functioning in Poland since 1977, as the part of the national health statistics. The system is based on a 15-percent random sample of copies of certificates of temporary incapacity for work issued by all health care units and authorised private medical practitioners. A certificate of temporary incapacity for work is received by every insured employee who is compelled to stop working due to sickness, accident, or due to the necessity to care for a sick member of his/her family. The certificate is required on the first day of sickness. Analyses of disease- and accident-related sickness absenteeism carried out each year in Poland within the statistical system lead to the main conclusions: 1. Diseases of the musculoskeletal and peripheral nervous systems accounting, when combined, for 1/3 of the total sickness absenteeism, are a major health problem of the working population in Poland. During the past five years, incapacity for work caused by these diseases in males increased 2.5 times. 2. Circulatory diseases, and arterial hypertension and ischaemic heart disease in particular (41% and 27% of sickness days, respectively), create an essential health problem among males at productive age, especially, in the 40 and older age group. Absenteeism due to these diseases has increased in males more than two times.

  13. Church unions and their consequences in Poland

    Directory of Open Access Journals (Sweden)

    Antoni Mironowicz

    2014-11-01

    Full Text Available Orthodox Christians in Poland have faced numerous attempts to be forced into union with the Roman Catholic Church, ranging from the thirteenth to the twentieth century. The first attempt at a union between the Roman Catholic Church and the Orthodox Church took place as early as the mid-thirteenth century. Another attempt at forcing the Orthodox Church into union with Rome took place during the reign of Ladislaŭ II Yagiello. The problem of church union returned in the reign of Alexander the Yagiellonian. When Ivan III rejected all projects for bringing the Florence such a union into practice, discussion on church union disappeared until the end of the sixteenth century. The mission of the papal legate, Father Antonio Possevino, to Ivan IV, had been intended to draw Moscow into the union, and its failure caused the papacy to concentrate its efforts on the Orthodox Church in Poland. The Ruthenian bishops’ obedience to the Pope was officially announced on the 8 October 1596. The decisions of the Uniate-Catholic synod were met with numerous protests from the Orthodox clergy and nobility. The larger part of the clergy and the faithful, together with bishops remained in the Orthodox camp. Despite the failure of the Brest Synod in fully uniting Orthodox and Roman churches, new union projects concerning the Orthodox Church in Poland continued to arise prior to the end of 18th century. The Vatican’s interest in the Orthodox Church in Central Europe was renewed at the end of the First World War. On April 1st, 1917, the Pope created the Congregation for the Oriental Churches which was responsibile for all issues relating to the activities of all the Eastern denominations. Despite aims at unification, attempts at church union have had a negative influence on the relations between the Roman Catholic and Polish Orthodox Church in contemporary Poland. The result of centuries of attempts at unification under the Pope has been fragmentation and division.

    2017-12-01

    The Santa Elena Ophiolite (SEO), located on the northwestern coast of Costa Rica, consists primarily of preserved oceanic mantle and crustal rocks thrust above an accretionary complex. The SEO is predominantly characterized by mantle peridotites (i.e., primarily spinel lherzolite with minor amounts of harzburgite and dunite) cut and intruded by minor pegmatitic gabbros, layered gabbros, plagiogranites, and doleritic and basaltic dykes. Previous studies have concluded that the complex formed in a suprasubduction zone (SSZ) setting based on the geochemical nature of the layered gabbros and plagiogranites (i.e., depleted LREE and HFSE and enriched LILE and Pb), as well, as the peridotites (i.e., low-TiO2, Zr, and V, and high MgO, Cr, and Ni)(Denyer and Gazel, 2009). Eighteen ultramafic samples collected during the winter 2010/2011 field season (SECR11) exhibit abundant evidence for melt-rock reaction (e.g., disseminated plagioclase and plagioclase-spinel, clinopyroxene-spinel, and plagioclase-clinopyroxene symplectites) and provide a unique opportunity to characterize the textural and chemical nature of melt-rock reaction in the SEO. We present the results of a petrologic investigation (i.e., petrography and electron probe microanalysis) of 28 thin sections (19 spinel lherzolites, of which 14 are plagioclase-bearing, 4 pyroxenite veins, and 5 harzburgites) derived from the SECR11 sample set. The results of this investigation have the potential to better our understanding of the nature of melt generation and migration and melt-rock interaction in the SEO mantle section and shed further light on the complex petrogenetic history of the SEO.

It is a deep eclipsing system, whose spectra show mostly single-peaked, Balmer emission lines and a rather intense He II line. There is also the presence of faint (often double-peaked) He I emission lines as well as several absorption lines, Mg I being the most prominent. All of these features point toward the affiliation of this object with the growing number of SW Sex-type objects. We developed a phenomenological model of an SW Sex system to reproduce the observed photometric and spectral features.

    2015-01-01

    Milestones of safeguards and non-proliferation activities are presented. Poland has declared its compliance with non-proliferation regime by ratification of Treaty of Nonproliferation of Nuclear Weapons in 1969. Poland concluded in 1972 Agreement with IAEA for application of safeguards — INFCIRC/153. Next steps in implementation of international safeguards were: ratification of Additional Protocol and introduction of Integrated Safeguards. After accession to European Union, Poland fulfils its safeguards obligations according to following international legal instruments: Treaty establishing Euratom, Agreement between Poland, European Commission and International Atomic Energy Agency in connection with implementation of Article III of Treaty of Non-proliferation of Nuclear Weapons — INFCIRC/193 and Additional Protocol to this Agreement — INFCIRC/193 Add.8. Detailed safeguards requirements are established by domestic Act of Parliament of 29th November 2000 — Atomic law and European Union's Regulations of Commission (Euratom) No 302/2005 on application of Euratom safeguards and the Commission Recommendation on guidelines for the application of Regulation (Euratom) No 302/2005. SSAC was established in 1972 as required by CSA. Activities related to accounting for and control of nuclear material were conducted from 1970s till 1990s by Central Laboratory for Radiological Protection and National Inspectorate for Radiation and Nuclear Safety. Currently, NAEA is responsible for collecting and maintenance of accounting data and safeguards inspections at all MBAs. Around 30 routine inspections/year are performed by the NAEA, Euratom and IAEA. In addition, usually 2 unannounced inspections/year under framework of Integrated Safeguards are conducted. In accordance with implementation of Global Threat Reduction Initiative seven shipments of high enriched nuclear fuel from research reactor to Russian Federation under supervision of safeguards inspectors from NAEA

  20. The steps to forming a joint venture IPP in Poland

    Energy Technology Data Exchange (ETDEWEB)

    Allen, Z.; Colligan, M.J.

    1998-07-01

    Poland represents the largest market in Central Europe with 38 million people and an installed electrical generating capacity of about 32 gigawatts. Since 1989, when the process of governmental restructuring along free market principals began, the allure to IPP developers has been evident, but is of yet unrealized. The natural model for IPP development in Poland would seem to be joint ventures with Polish generating companies. These enterprises already have sites, franchises, and a going business to contribute to a joint company. There are a number of reasons why so few deals have been concluded in Poland to date, and a number of barriers still exist that tend to hamper the realization of project finance funded power joint ventures. But, these barriers are not insurmountable. Overcoming them in the context of a joint venture relationship with a domestic partner requires patience, work, and an ability to bridge the gaps between the realities of working in a post-Communist environment and the practicalities of structuring projects that can be financed in the international capital markets. The new Energy Law in Poland establishes a framework for a viable private sector power generation business. But the enabling regulations are yet to be published or approved. There is still effective political risk on account of the uncertainty this creates. Pressure is mounting on the Polish Government, especially due to its expressed interest in joining the EU, to get the power sector to operate on private sector terms, if not in private hands. The trends are pointing in the direction of increased market driven policies and practices. The conclusion is that, despite the delays of the past, independent power projects will start to happen in Poland on a joint venture basis, with increasing frequency in the next years.

    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.

    Full Text Available Role of CSR Reporting. Evidence from Poland The paper addresses the issue of Corporate Social Responsibility (CSR reporting. The concept of CSR reporting is increasingly being discussed among practitioners and academics. The main objective of the paper is to investigate the trends of CSR reporting in Poland and to try to implement them in WIG 30 companies. The research confirmed the existing information chaos in these disclosures of socially responsible issues in various reports. An analysis of domestic and foreign literature has been performed which pointed to the multidimensionality of actions taken by companies in the context of CSR reporting. The research points to the need to apply standards regarding the disclosure of non-financial information in the form of reports for public limited companies.

    Bovine tuberculosis (bovine TB, bTB) is caused by bovine bacilli: Mycobacterium bovis and M caprae The studies conducted in Poland, in the National Bovine Tuberculosis Reference Laboratory in the Department of Microbiology of the National Veterinary Research Institute in Pulawy, show that animal tuberculosis in Poland is also caused by M caprae We here describe the identification and genotypic assessment of 52 isolates of M caprae obtained from Polish cattle and wild animals over the last five years. We show that strains isolated from bison have significant genotypic diversity and are distinct compared with the genotypes of strains isolated from cattle. Similarly, isolates from cattle herds can be highly genotypically variable. Formal designation of the members of the Mycobacterium tuberculosis complex is controversial in Poland; there is a gap in veterinary legislation with regard to bTB and no explicit mention of M caprae causing tuberculosis in animal. © British Veterinary Association (unless otherwise stated in the text of the article) 2018.

    Full Text Available We have investigated the dynamical stability of the proposed companions orbiting the Algol type short-period eclipsing binary SW Lyncis (Kim et al. 2010. The two candidate companions are of stellar to substellar nature, and were inferred from timing measurements of the system’s primary and secondary eclipses. We applied well-tested numerical techniques to accurately integrate the orbits of the two companions and to test for chaotic dynamical behavior. We carried out the stability analysis within a systematic parameter survey varying both the geometries and orientation of the orbits of the companions, as well as their masses. In all our numerical integrations we found that the proposed SW Lyn multi-body system is highly unstable on time-scales on the order of 1000 years. Our results cast doubt on the interpretation that the timing variations are caused by two companions. This work demonstrates that a straightforward dynamical analysis can help to test whether a best-fit companion-based model is a physically viable explanation for measured eclipse timing variations. We conclude that dynamical considerations reveal that the proposed SW Lyncis multi-body system most likely does not exist or the companions have significantly different orbital properties from those conjectured in Kim et al. (2010.

    1995-01-01

    The changed political situation and recognition of the acute destruction of the natural environment in Poland have caused a series of actions aimed at preventing further deterioration of Polish environment. One of the most important events which took place in the last few years was the enactment by the Polish Parliament in May 1991 of the Act on the National Ecological Policy. The basic assumption of the new environmental policy is a declaration that sustainable development will in future direct economic development in Poland. The aim of the presented paper is to introduce existing policy of air protection and instruments which have been implemented to protect the air. Special attention is paid to legislation instruments, introduction and enforcement of proper economic mechanisms strengthening air protection and foreign policy aiming at increasing foreign assistance for this objective. Pollutants involved include sulfur dioxide, nitrogen oxides, carbon dioxide and particulates from industry and coal-fired power plants. 9 refs

  7. Energy policies of Poland: 1994 survey

    International Nuclear Information System (INIS)

    1995-01-01

    This survey, conducted in co-operation with the Polish Government as a follow-up to the 1990 IEA Survey of Energy Policies of Poland, is intended to support Polish authorities responsible for designing measures and setting targets for energy policy. Another purpose is to report on progress made since 1990 in adapting the Polish energy sector to the requirements of a market economy. The survey documents and analyses recent developments in energy supply and demand, the energy pricing situation as of late 1994, Poland's energy supply security, the structure of the energy industries and the evolving relationship between the Government, public enterprises and private companies in the energy sector. It also looks at developments and initiatives in energy end-use efficiency and outlines the considerable environmental problems caused by energy production and use. The analysis points to areas where there is a need for further measures, comments on the Government's present policies and makes recommendations for the future. (authors). 41 figs., 51 tabs

    2014-08-01

    This paper presents the HW-SW co-design approach followed to tackle the design of the Hazard Detection and Avoidance (HDA) system breadboarding for the Lunar Lander ESA mission, undertaken given the fact that novel GNC technologies used to promote autonomous systems demand processing capabilities that current (and forthcoming) space processors are not able to satisfy. The paper shows how the current system design has been performed in a process in which the original HDA functionally validated design has been partitioned between SW (deemed for execution in a microprocessor) and HW algorithms (to be executed in an FPGA), considering the performance requirements and resorting to a deep analysis of the algorithms in view of their adequacy to HW or SW implementation.

  9. Uranium-thorium disequilibria and partitioning on melting of garnet peridotite

    Beattie, P.

    1993-01-01

    The abundances of isotopes in the 238 U decay series can be used as both tracers and chronometers of magmatic processes. In the subsolidus asthenosphere, the activity of each daughter isotope (defined as the product of its concentration and decay constant, and denoted by parentheses) is assumed to be equal to that of its parent. By contrast, ( 230 Th/ 238 U) is greater than unity in most recent mid-ocean-ridge and ocean-island basalts, implying that thorium is more incompatible (that is, it is partitioned into the melt phase more strongly) than uranium. Melting of spinel peridotite cannot produce the ( 230 Th) excesses, because measured partition coefficients for pyroxenes and olivine demonstrate that uranium is more incompatible than thorium for this rock. Here I report garnet-melt partitioning data which show that for this mineral-melt pair thorium does behave more incompatibility than uranium, thus supporting the suggestion that mid-ocean-ridge basalts (MORB) are produced by melting initiated at depths where garnet is stable. Using these data, I show that the observed ( 230 Th/ 238 U) ratios of MORB and most ocean-island basalts can be explained by slow, near-fractional melting initiated in the garnet stability field.

    2012-01-01

    Trichinellosis is still an epidemiological problem in Poland as well as in other countries in the European Union (EU). Across the EU, reporting cases oftrichinellosis is mandatory. In Poland, tirchinellosis is an endemic disease, occurring mainly in territories where it is customary to eat raw meat products prepared from pigs and wild boars. The aim of this work is to evaluate the epidemiological situation of trichinellosis in Poland in the year 2010 in comparison to previous years. Cases of trichinellosis infections were classified according to criteria contained in the definition approved by the European Committee on 28th April 2008 amending the decision 2002/253/EC, and was introduced in Poland in 2009. Case definitions used in are available at http://www.pzh. gov.pl/oldpage/epimeld/inne/Def_PL2_Rob1 h.pdf. An infection was classified and reported as Trichinella spp. if the genus of Trichinella that caused the infection was not specified using molecular examination. In 2010 the number of registered human trichinellosis cases was similar to the average number of cases from the last several years, and it did not exceed 55 (the exceptions were in 2004 and 2007, when larger outbreaks occurred). In 2010, 51 Trichinella infections were registered, yielding an infection rate of 0.13 per 100 000 inhabitants. The infections occurred in 5 voivodeships (table 1). Using the criteria from the definitions, 41 cases were classified as probable and 10 were confirmed cases. Trichinella infections diagnoses were based on the presence of clinical symptoms and an epidemiological link. Serological diagnostic tests confirming the presence of Trichinella antibodies was performed in approximately 20% of the cases. Four individual cases were reported, along with 4 outbreaks in which a total of 47 people were infected? The infections were generally mild. Twenty-two infected persons were hospitalised (43%). Just like in previous years, no trichinellosis-related deaths were reported. The

    2002-06-01

    In order to meet the accession requirements for membership to the European Union, Poland is currently restructuring its energy sector, and the initiative to privatise the electric power industry to full competition by 2005 is on course. This report describes the opportunities for foreign investors and suppliers of electrical equipment and services, particularly at this time when power demand is growing, the power grid infrastructure is ageing and obsolete components must be replaced. The total installed capacity in Poland is about 33,000 megawatts. This includes all installations of power plants and combined heat and power plants. An investment of $23 billion is anticipated by 2010 in order to modernize the electricity power industry and to meet the growing energy demand. Polski Siece Elektroenergetyczne, S.A. (PSE) is the state-owned company which controls Poland's high-voltage transmission grid. It operates a 220 kilovolt and 40 kV grid and holds the monopoly on acquiring and transmitting electricity in the country. Poland maintains grid interconnections with several other European countries and is looking to expand its network. Opportunities for Canadian suppliers lie in the areas of high-voltage power transmission equipment and services. Other opportunities lie in commercial prospects in sales of equipment and services. The report includes a section on international competition, and the Canadian position for both private- and public-sector companies. A section on market logistics describes distribution channels, market-entry considerations, import regulations, and export credit risks. A list of key contacts and support services is included with this report. refs., tabs.

    1995-01-01

    The objective of this article is to generate insights into the problems and opportunities faced by countries in transition in implementing environmental policy based on the recent experience of Poland. There is much to be learned from the experience of the country that arguably took the riskiest and boldest path of environmental and economic institutional change. The experience of Poland can be enlightening in terms of the problems and opportunities in establishing an institutional framework that can validate the long term legitimacy of sustainable development as a national goal. From the unique set of circumstances facing Poland, lessons can be derived for other countries in transition. The paper begins by introducing the basic welfare economics of institutional choice. The theoretical arguments are presented in terms general to institutional design and specific to environmental policy. Subsequently, the recent experience of Poland in terms of the problems faced and key environmental policy innovations are documented. The concluding section presents policy implications that can be drawn from the Polish experience and speculates about their applicability to other countries in transition. 28 refs., 5 figs., 8 tabs

  15. Modification of an ancient subcontinental lithospheric mantle by continental subduction: Insight from the Maowu garnet peridotites in the Dabie UHP belt, eastern China

    Chen, Yi; Su, Bin; Chu, Zhuyin

    2017-05-01

    Orogenic mantle-derived peridotites commonly originate from the subcontinental lithospheric mantle (SCLM) and thus provide a key target to investigate the modification of the SCLM by a subducting slab. The Maowu ultramafic rocks from the Dabie ultrahigh-pressure (UHP) metamorphic belt have formerly been debated as representing cumulates or mantle-derived peridotites. Detailed petrological and geochemical data presented in this study provide new constraints on the origin and formation of the peridotites involving melt depletion in the ancient SCLM and deep crustal metasomatism. The Maowu garnet dunites have refractory bulk compositions characterized by high Mg# (91.9-92.0) and Ni (2537-2892 ppm) values and low Al2O3 (0.26-0.76 wt.%), CaO (0.05-0.32 wt.%), TiO2 (China craton. Many garnet orthopyroxenite veins crosscutting the Maowu dunites preserve abundant metasomatic textures and show variable enrichment in incompatible elements. Mineral and whole-rock chemistry indicate that these veins represent metasomatic products between the wall dunites and silica-rich hydrous melts under UHP conditions. The veins show large variations in platinum-group element (PGE) signatures and Re-Os isotopes. The garnet-poor orthopyroxenite veins are characterized by low Al2O3 ( 6 wt.%) and S (99-306 ppm) contents and show melt-like PGE patterns and high 187Os/188Os ratios (up to 0.36910). These features, combined with the occurrence of interstitial sulfides in the garnet-rich orthopyroxenite veins, suggest that crust-derived sulfur-saturated silicate melts may have significantly modified the PGE signature and destroyed the Re-Os systematics of the SCLM. However, when the crust-derived silicate melts became sulfur-depleted, such melts would not significantly modify the PGE patterns, radiogenic Os-isotope compositions or the Re-depletion model ages of the SCLM. Consequently, deep crust-mantle interactions in continental subduction zones could induce high degrees of Os isotopic

    Carbon dioxide is considered to be the main challenge for the coal-based power generation as well as for any other industrial application of coal. Poland's energy sector is primarily based on coal combustion that covers almost 90% of demand. Future development of that sector depends on the restriction on value of carbon dioxide emission or trading allowances. There are two main technological approaches to development of new coal based generation capacity, namely: gasification and pre-combustion capture; supercritical combustion and post-combustion capture. The current situation in development of three this type projects in Poland is presented.

    This statement shortly describes the changes in the telecommunication market that have taken place in the last 12 years, during the socio-economical transformation in Poland. It concerns economical, legal and technical problems related to the development of the telecommunications in Poland based on the principles of the market economy. Especially it is related to the commercialization of this sector, what has been a result of the changes of the principal law ruling the national economy including changes ot the telecommunication law. Changes of the law enabled the creation of the commercial company Polish Telecom and opened the way to the privatization of this company. Due to the changed law the way to the step-by-step liberalization and de-monopolization process has been also opened in Poland. It has caused fully digital modernization of telecommunication network, introduction new services such as cellular communications and Internet services, as well as rapid development of the market, what has expressed in multiplication of number of subscribers of stationary telephony, creation of the big cellular market and new increasing Internet market. The statemnet also refers to present difficulties in development of this market and as well as to the prospects for the future developments.

    Full Text Available This article presents the results of historical research on the operation of British accounting firm Whin-ney, Murray & Co in Poland before World War II. Based on our findings this was the only foreign ac-counting firm active in Poland at that time. Following their clients, British accounting firms expanded their operations abroad at the turn of the 19th century. During the 1920s and 1930s the number of audit assignments on the European continent increased rapidly, which necessitated the establishment of branches (offices in major European cities and industrial districts. Whinney, Murray & Co set up an office in Warsaw in 1932 taking into account its convenient location as a base for undertaking audit assignments throughout the Eastern European region. The Warsaw office concentrated initially on inter-national clients active in Poland but was also engaged in audits of Polish power plants and participated as financial advisor in the electrification program of Polish railways with involvement of British investors. Whinney, Murray & Co contributed to the development of Polish-British economic cooperation before World War II. Its representative was one of the founders of the Polish-British Chamber of Commerce established in Warsaw in 1933.

    2015-09-01

    Full Text Available Because of its harmfulness to human health, asbestos has been banned in 55 countries, including the EU. In Poland, the use and production of asbestos and asbestos-containing products has been forbidden since 1997. However, there is no precise data about the amount of asbestos-containing products to be eliminated from the territory of Poland. This survey aims to identify characteristics that have a significant impact on the estimation of asbestos-containing products used in Poland. Statistical correlation between the results of the physical inventory count done in 155 municipalities was examined. As a result of the survey it was found that the amount of asbestos-cement roofing depends on the following factors: the number of individual farms in the village, the distance from the asbestos manufacturing plants, the age of the buildings and the economic situation of municipality. The results obtained may contribute to the ability to predict the amount of asbestos-containing products used in other municipalities.

    In Poland 11 measles cases were registered in 2004 (0.03 per 100,000 population), of which 3 were cases imported from Chechnya. Of 8 local cases, 3 cases occurred in unvaccinated persons, 2 in persons vaccinated with one dose and 3 in vaccinated with two doses of measles vaccine (administered at the age of 13-15 months and 7 years). The most affected age groups were 1-year old children (0.29 per 100,000 population) and 6-year olds (0.25). Out of 11 reported cases 2 were hospitalized. There were no deaths attributed to measles. Poland participates in the WHO Measles Elimination Strategy. Presently, the most important is the maintenance of a sensitive and timely surveillance of measles and measles-compatible cases, with serologic testing of one suspect case per 100,000 population. The performance of the surveillance system was insufficient with only 44 measles-compatible cases reported in 2004 (12% of expected reports). Serologic confirmation of cases was also insufficient, with 5 cases confirmed in WHO accredited laboratory. These results indicate the need to maintain the high immunisation coverage and improve measles surveillance system.

    1999-06-01

    Full Text Available In this paper all the photoelectric times of minimum for the triple star SW Lyn have been analyzed in terms of light-time e ect due to the third-body and secular period decreases induced by mass transfer process. The light-time orbit determined recently by Ogloza et al.(1998 were modi ed and improved. And it is found that the orbital period of SW Lyn have been decreasing secularly. The third-body revolves around the mass center of triple stars every 5y.77 in a highly eccentric elliptical orbit(e=0.61. The third-body with a minimum mass of 1.13M may be a binary or a white dwarf. The rate of secular period-decrease were obtained as ¡âP/P = -12.45 x 10^-11, implying the mass-transfer from the massive primary star to the secondary. The mass losing rate from the primary were calculated as about 1.24 x 10^-8M /y. It is noticed that the mass-transfer in SW Lyn system is opposite in direction to that deduced from it's Roche geometry by previous investigators.

    This paper presents the situation of the profession of medical physicists in Poland. The official recognition of the profession of medical physicist in Polish legislation was in 2002. In recent years, more and more Universities which have Physics Faculties introduce a medical physics specialty. At present, there are about 15 Universities which offer such programmes. These Universities are able to graduate about 150 medical physicists per year. In 2002, the Ministry of Health introduced a programme of postgraduate specialization in medical physics along the same rules employed in the specialization of physicians in various branches of medicine. Five institutions, mostly large oncology centres, were selected as teaching institutions, based on their experience, the quality of the medical physics professionals, staffing levels, equipment availability, lecture halls, etc. The first cycle of the specialization programme started in 2006, and the first candidates completed their training at the end of 2008, and passed their official state exams in May 2009. As of January 2016, there are 196 specialized medical physicists in Poland. Another about 120 medical physicists are undergoing specialization. The system of training of medical physics professionals in Poland is well established. The principles of postgraduate training and specialization are well defined and the curriculum of the training is very demanding. The programme of specialization was revised in 2011 and is in accordance with EC and EFOMP recommendations. Copyright © 2016 Associazione Italiana di Fisica Medica. Published by Elsevier Ltd.

    The adenomatous polyposis coli (APC) tumour suppressor gene is mutated in about 80% of colorectal cancers (CRC) Brannon et al. (2014) [1]. APC is a large multifunctional protein that regulates many biological functions including Wnt signalling (through the regulation of beta-catenin stability) Reya and Clevers (2005) [2], cell migration Kroboth et al. (2007), Sansom et al. (2004) [3], [4], mitosis Kaplan et al. (2001) [5], cell adhesion Faux et al. (2004), Carothers et al. (2001) [6], [7] and differentiation Sansom et al. (2004) [4]. Although the role of APC in CRC is often described as the deregulation of Wnt signalling, its other biological functions suggest that there are other factors at play that contribute to the onset of adenomas and the progression of CRC upon the truncation of APC. To identify genes and pathways that are dysregulated as a consequence of loss of function of APC, we compared the gene expression profiles of the APC mutated human CRC cell line SW480 following reintroduction of wild-type APC (SW480 + APC) or empty control vector (SW480 + vector control) Faux et al. (2004) . Here we describe the RNA-seq data derived for three biological replicates of parental SW480, SW480 + vector control and SW480 + APC cells, and present the bioinformatics pipeline used to test for differential gene expression and pathway enrichment analysis. A total of 1735 genes showed significant differential expression when APC was restored and were enriched for genes associated with cell polarity, Wnt signalling and the epithelial to mesenchymal transition. There was additional enrichment for genes involved in cell-cell adhesion, cell-matrix junctions, angiogenesis, axon morphogenesis and cell movement. The raw and analysed RNA-seq data have been deposited in the Gene Expression Omnibus (GEO) database under accession number GSE76307. This dataset is useful for further investigations of the impact of APC mutation on the properties of colorectal cancer cells.

    For reduction of greenhouse effect gas emission by Japan- Poland joint project, research was made on the improvement plan of Huta Katowice, a typical ironworks in Poland. The applicability of energy saving facilities was studied for the coke factory, sintering factory, blast furnace and converter which are consuming the most amount of energy in Huta Katowice, from the viewpoints of the amount of energy saving and CO{sub 2} reduction, and an investment effect. Research was also made on the power plant, flow of by-product gas, generated energy and purchased energy for obtaining the total energy consumption. From the energy saving research results for every process, the priority of the improvement plan was prepared. The proposed plan showed huge reduction of energy and greenhouse effect gas emission. Although the plan is too serious for comfort because of current low energy cost in Poland, it becomes reasonable if a lower-interest fund loan is granted, from the viewpoint of an investment effect.

    2007-01-01

    Standardized low-resolution brain electromagnetic tomography (sLORETA) is a widely used technique for source localization. However, this technique still has some limitations, especially under realistic noisy conditions and in the case of deep sources. To overcome these problems, we present here swLORETA, an improved version of sLORETA, obtained by incorporating a singular value decomposition-based lead field weighting. We show that the precision of the source localization can further be improved by a tomographic phase synchronization analysis based on swLORETA. The phase synchronization analysis turns out to be superior to a standard linear coherence analysis, since the latter cannot distinguish between real phase locking and signal mixing

  11. Macroeconomic surroundings of transport and logistics sector in Poland during the global economic crisis

    2012-03-01

    Full Text Available During the last quarter of 2009, Poland has entered a phase of economic growth. Presently, despite the emerging financial problems in the EU zone, positive market sig-nals can still be observed in Poland, for example increase in domestic and external de-mand, incoming orders in the industry sector and production capacity in companies. The-se changes enhance growth of production in the industry and construction sectors, which are perceived as key sectors for generating demand for transport services. Therefore the lack of market signals that indicate economic slowdown means that the conditions for transport and logistics sector development in Poland are not expected to deteriorate. The key threat to the stability of economic growth in Poland, and in consequence to transport and logistics companies, is the excess debt of public finance sector.

    The first well to operate the SW-SAGD process in the Orinoco oil belt in Venezuela was built in 2006 by Petroleos de Venezuela S.A (PDVSA). SW-SAGD is a thermal recovery process consisting in the injection of steam through a horizontal well pipe insulation. In order to follow the behavior of steam and the movement of heated fluids in such a process better, PDVSA installed a monitoring system composed of high temperature fiber optic and thermocouple type sensors. The aim of this paper is to assess the thermal behavior of reservoirs in wells under the SW-SAGD process. A pilot test has been conducted over the last 3 years. Results show an increase in production and estimations show a recovery factor twice as high as in other wells. This study demonstrated that SW-SAGD is an excellent alternative solution to stimulate reservoirs in the Orinoco oil belt and valuable information on the reservoir's thermal behavior was established.

    Colorectal cancer (CRC) is one of the most common causes of cancer-related death in the world. The expression of N-myc downstream-regulated gene 2 (NDRG2) is down-regulated in CRC. The aim of this study was to investigate the effect of NDRG2 overexpression on cell proliferation and invasive potential of SW48 cells. SW48 cells were transfected with a plasmid overexpressing NDRG2. After stable transfection, the effect of NDRG2 overexpression on cell proliferation was evaluated by MTT assay. The effects of NDRG2 overexpression on cell migration, invasion and cell motility and matrix metalloproteinase 9 (MMP9) activities were also investigated using matrigel transwell assay, wound healing assay and gelatin zymography, respectively. MTT assay showed that overexpression of NDRG2 caused attenuation of SW48 cell proliferation. Transwell and wound healing assay revealed that NDRG2 overexpression led to inhibition of migration, invasion, and motility of SW48 cells. The overexpression of NDRG2 also reduced the activity of secreted MMP-9. The results of this study suggest that NDRG2 overexpression inhibits proliferation and invasive potential of SW48 cells, which likely occurs via suppression of MMP-9 activity.

    Full Text Available Abstract Background Migration and ethical recruitment of health care workers is receiving increased attention worldwide. Europe’s aging population is creating new opportunities for medical doctors for finding employment in other countries, particularly those of a better standard of living. Methods We conducted a survey among 1214 medical students in five out of eleven universities in Poland with medical schools in October 2008. A series of statistical tests was applied to analyse the characteristics of potential migrants. Projections were obtained using statistical analyses: descriptive, multifactorial logistic regression and other statistical methods . Results We can forecast that 26–36% of Polish medical students will emigrate over the next few years; 62% of respondents estimated the likelihood of emigration at 50%. Students in their penultimate year of study declared a stronger desire to migrate than those in the final year. At the same time, many students were optimistic about career opportunities in Poland. Also noted among students were: the decline in interest in leaving among final year students, their moderate elaboration of departure plans, and their generally optimistic views about the opportunities for professional development in Poland. Conclusions The majority of Polish students see the emigration as a serious alternative to the continuation of their professional training. This trend can pose a serious threat to the Polish health care system, however the observed decline of the interest in leaving among final year students, the moderate involvement in concrete departure plans and the optimistic views about the opportunities for professional development in Poland suggest that the actual scale of brain drain of young Polish doctors due to emigration will be more limited than previously feared.

    Full Text Available Azolla filiculoides has been an ephemeral plant in Poland since the end of the 20th century. In the last 15 years this species appeared in 5 locations in south-west Poland. Habitat and plants of two populations became destroyed, three other still exist. A. filiculoides occurs in eutrophic or even polluted water where it forms dense mats, up to 10 cm thick. It stays sterile and propagates only in a vegetative manner. Frost resistance of Lower Silesia populations is higher than reported so far; fern may winter and rebuild the population after frost reaching 22oC. Size of the populations is changeable during the vegetation season. A. filiculoides occurs in water habitats and plant communities in which it substitutes Lemna minor.

  19. Environmental regulatory reform in Poland: lessons for industrializing economies

    Brown, H.S.; Angel, D. [Clark University, Worcester, MA (USA). George Perkins Marsh Institute

    2000-09-01

    This paper examines the environmental regulatory reform in Poland during the 1990s and uses the findings to consider the extent to which elements of successful regulatory systems are transferable across national boundaries. Drawing on five case studies of privatized firms, a mailed questionnaire, and policy and institutional analysis, it investigates how Poland developed an effective system for managing industrial pollution while also achieving considerable socioeconomic progress. The fundamental legitimacy of the regulators and regulatory process, the availability of information about firms and regulatory intents, and the capacity for case-specific decision-making are among the key explanatory factors. The study also shows how in Poland a good 'fit' between regulatory institutions and policies on one hand and their social context on the other hand has evolved, and how it contributes to the effectiveness of the regulatory system. Industrializing economies can indeed simultaneously pursue environmental protection and socioeconomic welfare, but elements of a proven regulatory system cannot be automatically adopted among countries and cultures. Learning from each other's experience must be sensitive to the cultural and institutional context of each regulatory system. 42 refs., 3 figs., 1 tab.

  20. Sustainable Rural Development Policy in Poland – Environmental Aspects

    Directory of Open Access Journals (Sweden)

    Mosiej Józef

    2014-12-01

    Full Text Available The author discusses issues of sustainable development in rural areas in Poland from the perspective of natural resources management. Sustainable development of rural areas is the way of managing which links economic, social and ethical principles with ecological safety. This may be reached by proper management, directed on cautious usage of ecosystems’ self-controlling mechanisms, with the progress of science and technology. Agriculture in Poland is one of the most important sectors from an economic perspective and its importance is greater in Poland than in other countries in the EU. It has an influence not only on the social and economic situation of the rural population, but also on the natural environment, structure of landscape and biodiversity. From ecological point of view, functions of rural areas are not only being a place for production of food, resources for industry and green energy, but also supplying environmental goods such as protection of biodiversity and influencing air and water quality as well as landscape. The author presents ways to reduce the pressure of agricultural activities on water resources in the region, catchment and farm scale

    2008-07-01

    The present work presents an extensive numerical study, using a commercial reservoir simulator, on the recovery of heavy oil by steam injection assisted by gravity drainage in single horizontal wells. The goal is to study several strategies to improve performance of the Single Well - Steam Assisted Drainage Gravity (SW-SAGD), a new but promising thermal recovery technique aimed at exploitation of heavy oils. The strategies are basically made up of two measures: cyclic steam injection prior to the main injection-production process; and well bore splitting into injection and production zones by packer settings. The measures are scrutinized when used separately or together. Cyclic injection is varied according to cycle duration. Comparisons are made between the performance of oil recovery for the developed strategies and the performance of the traditional dual well SAGD technique with similar operating parameters and field conditions. The results point out the best strategy regarding key parameters such as the oil recovery factor and the steam oil ratio. Results were also verified for variations of rock and fluid properties in the range of a typical heavy oil reservoir. As a result, a new strategy for the SW-SAGD process is presented, providing oil recovery, which is higher than that yielded by the equivalent DW-SAGD. (author)

    SW Sextantis stars are a relatively large group of cataclysmic variables (CVs) which plays a fundamental role in our understanding of CV structure and evolution. Very little is known about the properties of their accreting white dwarfs and their donor stars, as the stellar components are usually outshone by an extremely bright accretion flow. Consequently, a proper assesment of their evolutionary state is illusionary. We are monitoring the brightness of a number of SW Sex stars and request here Gemini/GMOS-N ToO time to obtain orbital phase-resolved spectroscopy if one of them enters a low state, since this is the only opportunity for studying the stellar components individually. These data will be used to accurately measure the binary parameters, white dwarf temperature, and distance to the system for a SW Sex star for the first time. The measured stellar masses and radii will especially be a precious input to the theory of compact binary evolution as a whole.

    SW Sextantis stars are a relatively large group of cataclysmic variables (CVs) whose properties contradict all predictions made by the current CV evolution theories. Very little is known about the properties of their accreting white dwarfs and their donor stars, as the stellar components are usually outshone by an extremely bright accretion flow. Consequently, a proper assesment of their evolutionary state is illusionary. We are monitoring the brightness of a number of SW Sex stars and request here Gemini/GMOS-N ToO time to obtain orbital phase-resolved spectroscopy if one of them enters a low state, since this is the only opportunity for studying the stellar components individually. These data will be used to accurately measure the mass ratio of the system which, combined with the orbital inclination derived from modelling of either the disc eclipses in the high state or the ellipsoidal modulation in the low state, will eventually provide the first detailed system parameters for any SW Sex star.

    Full Text Available The article presents an outline of the issue concerning formulation of a marketing strategy and the possibility of using the knowledge on consumers' preferences for organic development of farms and their products on the example of southern Poland. The paper analyses the distribution process of organic food in the aspect of developing innovative marketing strategies. The studies were performed in 50 organic farms and on the example of 100 respondents from the region of southern Poland. In the opinion of the surveyed representatives of the organic food producers, a competitive advantage of their offer depends the most on the health values, brand, reputation, and taste. Moreover, information on products and the form and place of their sale are significant. The analysis shows that the knowledge is the most eagerly obtained from the Internet. Thus, producers should publish their profiles and pages on social media and business portals.

    The capercaillie (Tetrao urogallus) is one of Poland's most endangered bird species, with an estimated population of 380-500 individuals in four isolated areas. To study these natural populations in Poland further, more than 900 non-invasive genetic samples were collected, along with samples from 59 birds representing large, continuous populations in Sweden and Russia; and from two centres in Poland breeding capercaillie. Microsatellite polymorphism at nine loci was then analysed to estimate within-population genetic diversity and genetic differentiation among populations. The results confirmed that isolation of populations and recent decreases in their sizes have reduced genetic diversity among capercaillie in Poland, with all the country's natural populations found to be experiencing the genetic after-effects of demographic bottlenecks. The results of analyses of genetic differentiation and structure further suggest the presence of a 'lowland' cluster (encompassing birds of the Augustowska and Solska Primaeval Forests in Poland, and of Sweden and Russia), and a Carpathian cluster. Capercaillie from Sweden and Russia are also found to differ markedly. The Polish lowland populations seem more closely related to birds from Scandinavia. Our genetic analysis also indicates that the stocks at breeding centres are of a high genetic diversity effectively reflecting the origins of founder individuals, though identification of ancestry requires further study in the case of some birds. Overall, the results sustain the conclusion that the Polish populations of capercaillie from the Carpathians and the lowlands should be treated as independent Management Units (MUs). This is to say that the breeding lines associated with these two sources should be maintained separately at breeding centres. The high level of genetic differentiation of birds from the Solska Primaeval Forest suggests that this population should also be assigned the status of independent MU.

    International non-proliferation efforts have been taken to reduce the risk related to nuclear materials and radioactive sources. The physical security of nuclear facilities to prevent acts of sabotage or terrorism and to protect nuclear materials against loss or seizure is an essential element of the nuclear non-proliferation regime. Iraq case and the end of the Cold War have influenced the development of co-operation and openness in many countries. Poland due to: - its geolocation, - a growing number of post Chernobyl contamination transports and - high risk to become a transit country in illicit trafficking of nuclear materials and radioactive sources, initiated deployment of the fixed installation instruments at the border check-points. Since the end of 1990 to now 103 such devices have been installed. Broader involvement in combating illicit nuclear trafficking of Border Guards, Customs Services, Police and Intelligence Security has been noticed. Paper presents Poland's experience in implementing national prevention measures to reduce nuclear proliferation risk and in detecting capabilities against illicit nuclear traffic. (author)

    Bilikiewicz, A

    1999-01-01

    The author describes present medical student curricula in psychiatry in Polish medical schools based on the questionnaire sent to all the lecturers of the subject in Poland. The questionnaire contained questions concerning the schedule of lectures, seminars and classes (the list of topics) as well as the number of hours of the forms of activities like interpersonal training, discussion groups, internship, etc. We also asked on which year of studies the course in psychiatry took place. The questionnaire included our request to describe the level of integration of psychiatry and other pre-clinical and clinical subjects as well as to enclose a recommended reading list (handbooks and other items of literature). The last question dealt with the problem of assessment of lectures and classes by students. The results of the questionnaire reveal great differences in the curricula of psychiatry in various schools in Poland. The differences lie both in the courses and the number of hours devoted to teaching psychiatry (in most schools it was 120 hours or less). In 7 schools students learn psychiatry in the 6th i.e. the last year of their studies. In 2 schools lectures in psychiatry are given in the th year. In Kraków and Gdańsk the courses in psychiatry consist of 150 and 160 hours respectively. The author proposes unification of the curricula in psychiatry concerning both the number of hours of classes and lectures, and topics as well as introducing the diagnostic and classifying criteria ICD-10 (WHO) since Poland is going to join EU.

    The aim of the study is to assess epidemiological situation of infectious and parasitic diseases in Poland in 2014, and an indication of the potential health risks from communicable diseases occurring in other areas of the globe. This paper is a summary of the analysis and evaluation of the results of epidemiological surveillance of infectious diseases in Poland in 2014, and those elements of European and global epidemiological background, which in this period had an impact on the epidemiological situation in Poland or constituted a threat. The main source of data for this study are statistical reports included in annual bulletins “Infectious diseases and poisoning in Poland in 2014” and “Immunizations in Poland in 2014” (NIPH-PZH, GIS, Warsaw 2015) and the data contained in the articles of „Epidemiological chronicle” presented in the Data on deaths are based on the statement of the Department for Demographic Research and Labour Market CSO presenting numbers of deaths from infectious and parasitic diseases registered in Poland in 2014, and in the previous years. Upper respiratory tract infection classified as “suspected flu and the flu season” in the since many years are the largest position among the diseases subject to disease surveillance. In the last decade, particularly large increase in the incidence of upper respiratory tract infection was reported in the flu season 2013., when the increase in comparison to the median of years 2008-2012 amounted to 189.8%. In 2014. Number of reported cases was 3 137 056 which represented a nonsignificant decrease of 0.8% compared with the previous year. However, compared to the median of the years 2008-2012 it was an increase of 187.4%.

    Full Text Available One important need in the context of peatland restoration is to gain knowledge of soil organic matter quality and current soil-forming process in degraded peatlands. The aim of this study was to evaluate the impact of long-term drainage on soil transformation processes. In autumn 2012, soil survey and sampling was carried out on five shallow peatlands in the Central Sudeten Mountains (Poland which had been drained for forestry use in the late 1800s or early 1900s. Four organic soils (Histosols and one organo-mineral soil (Histic Gleysol were studied. The surface soil horizons were mainly transformed due to long-term forestry drainage. Increased aeration of these layers had enhanced their content of labile forms of carbon and they were undergoing secondary transformation. Soil transformation was more advanced in fen peatlands than in transitional mire or raised bogs. Only the fens exhibited characteristic evidence of the moorsh-forming process. Further drying of these soils will negatively affect their rewetting potential and significantly reduce the effective application of restoration treatments. In order to reduce organic matter transformation and loss from the investigated peatland areas, their drainage ditches should be blocked. Additionally, some trees should be removed from their central areas to reduce evapotranspiration.

    Poland has a strong ambition to evolve rapidly into a knowledge-driven economy. Since 2004, it has been the largest beneficiary of European Union cohesion policy funds among all member states. Between 2007 and 2013, Poland was allocated approximately EUR 67 billion, whereas for 2014-2020 the EU budget earmarked EUR 82.5 billion for Polish cohesion policy. This means that in the coming years, Poland's R&D intensity will grow. But the question remains: is 27 years of free market economy enough to enable a country's economy to become knowledge-based ? This paper offers an analysis of Polish R&D expenditures and investments in terms of their sources (business, government or higher education sectors), types (European Union or state aid) and areas of support (infrastructure, education or innovation). It also characterises the Polish R&D market with its strengths and weaknesses. Then, it examines the process of technology transfer in Poland, comparing it to best practice. Finally, the paper lays out the barriers to effective commercialisation that need to be overcome, and attempts to answer the question raised in its title.

    Full Text Available Campsis radicans is an attractive climber with typical ornitogamous flowers, native to North America. In natural conditions this out-crossed plant is pollinated mostly by hummingbirds. In Poland, where C. radicans is cultivated as ornamental, it rarely sets seeds. The questions addressed in the present study were: (1 What animals pollinate its flowers in Poland?, and (2 What is the reason for infrequent fruit set? Field studies conducted in five localities in Poland showed that the principal pollinator is Apis mellifera, and the lack of seeds is usually caused by pollinator limitation or absence of genetically different pollen donor plants.

    Full Text Available Social media are very popular around the world. More and more people adopt this method of communication, as it brings instant and effective ways to stay in touch with ones relatives, coworkers, brands and products. Poland is no exception, as all major brands of the social sphere have decided to prepare localized versions of their product for the Polish market. One could say that Poland is following the global trends very accurately as Facebook has dominated the market and pushed out the indigenous services Brands and corporation utilize the medium to get in touch with their consumers. On the other side, there are public institutions like universities, local governments , that should be interested in getting in touch with people, as reaching out to one’s potential customers has never been easier. This is happening, but on a very small scale and many attempts fail. In this paper, Author explores the possible reasons behind the situation and attempts to form a prognosis for the market of social media in Poland.

    Full Text Available In Poland and worldwide, corporate social responsibility has a growing interest of managers, business institutions, investors and the government. Thus, it becomes progressively determinant of corporate governance and priority in building a comprehensive development strategy. CSR is used by large companies. However, this does not mean that SMEs sector companies operate less responsible than large one. Each enterprise, regardless of size, operates in a specific social surroundings and market environment, which are affected by different groups of stakeholders. They may affect enterprise reinforcing effect on - contribute to its success or failure. It is therefore important that the managers should be able to identify social groups in the enterprise and its environment and respect their claims, needs, rights and expectations. The aim of this paper is to show the application of CSR by micro, small and medium-sized enterprises in Poland and the manner of result presentation. This article lists tools of corporate social responsibility, examples of practices and research results in the SMEs sector in Poland.

    As landowners occupied with agricultural production comprise a sizeable part of the populations in mid- and western European countries, it seemed reasonable to assess the organization of health care systems concerning farmers and their families in Poland and Germany. Both countries have similar geographical conditions and rural environments. It so happens that in Poland the principles of the system of agricultural insurance (KRUS) is based on the experiences of Germany and France. Basically, both in Poland and Germany, the agricultural health insurance companies provide the same insurance cover as other health insurance companies. In both countries, under certain conditions, in the case of illness, the insured farmers receive instead of sickness benefit operational assistance and home help. In spite of the similarities that characterize both administrations, many particular differences are to be noted, e.g. the farmers' social insurance in Poland is subject to only one ministry, in contrast to Germany where two ministries are responsible for farmers' social insurance. In Poland, KRUS is a monopolistic organization, whereas in Germany, nine similar independent structures fulfil the task of a health insurance company. Needless to say, many more funds are available for prevention, treatment and rehabilitation in Germany than in Poland, due to obvious differences in the overall national income.

    Preliminary survey of Rn concentration indoors by means of track detectors and y-ray dose rate with the use of TLD in almost 500 homes in selected areas of Poland was performed in the late 1980s. It was concluded that radon contributes 1.16 mSv i.e. about 46 per cent of the total natural environment ionizing radiation dose to the Polish population. Comparison of the average radon concentrations in 4 seasons of a year and in 3 groups of buildings: masonry, concrete and wood, revealed that the ground beneath the building structure is likely the dominant source of radon indoors. Since the National Atomic Energy Agency in its regulations of 1988-03-31 set up the permissible limit of the equilibrium equivalent concentration of radon in new buildings (equal 100 Bq/m3), the nation-scale survey project for radon in buildings has been undertaken. These regulations were supposed to take effect in 1995-01-01. The project has 3 objectives: to estimate the radiation exposure due to radon daughters received by Polish population to identify radon-prone areas in Poland to investigate dependence of the indoor radon concentrations on such parameters as: type of construction material, presence (or absence) of cellar under the building, number of floor

    2015-11-01

    Full Text Available The pattern of morphometric differentiation between two populations of pumpkinseed (Lepomis gibbosus inhabiting distinctively different habitats in north-west Poland was examined. Fish were collected at sites that differ in water temperature and hydrology – an ambient temperature, urban pond vs an artificially-heated drainage channel, respectively. In principal component analysis, the first and second components, which accounted for 40% and 11 %, respectively, of the variability between the habitat types, revealed that the observed differences were related to head and body dimensions, with specimens from the heated site having generally larger heads, higher bodies, and longer anterior components. Larger body size is normally associated with greater survival in unnatural and highly variable environments.

    We determine the improvement factor c{sub SW} in one-loop lattice perturbation theory for the plaquette and Symanzik improved gauge actions. The fermionic action is O(a) clover improved with one-time stout smearing. c{sub SW} is derived from the one-loop correction to the quark-quark-gluon vertex in the off-shell regime. We give a first numerical value for the one-loop contribution to the non gauge-invariant improvement coefficient c{sub NGI} for the quark field using the plaquette action. A discussion of mean field improvement is included. (orig.)

    Full Text Available Academic aspects of management accounting and controlling in Poland since the 1990s Management accounting (MA systems in enterprises in Poland are shaped by numerous economic and institutional factors. Normative drivers such as teaching at the university level, academic research and publications of Polish academics (which are, in turn, influenced by the development of MA and con-trolling in Western countries are of major importance. The aim of the paper is to recognize and present the scope of the impact that the Anglo-American concept of management accounting, and the controlling concept according to the approach in German-speaking countries, have had on the academic aspects of MA in Poland since 1990. The authors answer in the paper six explorative research questions. The basis for the answers to these questions is a literature study, a review and thematic classification of articles concerning MA and controlling, published in the two main Polish journals in this area, and a survey conducted by the authors among heads of accounting departments at universities and other entities of further education in Poland. The paper provides arguments confirming that there is no uni-form perception of the relationship between MA and controlling among Polish accounting researchers, that research topics in Poland are dominated by the Anglo-American concept of MA, and that educa-tional programs on accounting at university level have a preference for the term management account-ing, although they also offer courses on controlling.

    Mantle xenoliths from the island of El Hierro, the youngest of the Canary Islands, have been studied to characterize fluxes of carbon in the lithosphere of an OIB volcanism region. Fifteen xenoliths (4-10 cm in diameter) were collected in a rift lava flow (15-41 ka) at a new xenolith locality in El Julan cliff (S-SW of the island). Peridotites consist of protogranular to porphyroblastic spinel harzburgites, lherzolites, and subordinate dunites. One spinel clinopyroxenite, and one olivine-websterite were also analyzed. Ultramafic xenoliths were classified as HEXO (harzburgite and dunite with exsolved orthopyroxene), HLCO (harzburgite and lherzolite containing orthopyroxene without visible exsolution lamellae), and HTR (transitional harzburgite with exsolved orthopyroxene porphyroclasts, and poikilitic orthopyroxene) following [1]. While HLCO and HTR peridotites contain mostly CO2 fluid inclusions, HEXO peridotites preserve an early association of melt/fluid inclusions containing dominantly carbonate/sulfate/silicate glass, evolving to carbonate/sulfate/phosphate/spinel aggregates, with exsolved CO2 (± carbonates, anhydrite and H2O). Chemical and Raman analyses identify dolomite, Mg-calcite, anhydrite, sulfohalite [Na6(SO4)2FCl] (± other anhydrous and hydrous alkali-sulfates), apatite, and Cr-spinel in the inclusions. Sulfides are noticeably absent. The microstructure and chemical composition of the metasomatic fluids indicate that the peridotites were infiltrated by a carbonate-sulfate-silicate melt/fluid enriched in CO2, H2O, and P. A mantle origin for this fluid is supported by high densities of CO2inclusions (> 1g/cm3), determined by Raman microspectroscopy and cross-checked by microthermometry. Consequently, El Julan peridotites provide the first evidence for liberating oxidized C and S fluxes from the Earth lithosphere in an OIB source region, and suggest that oxidation of sulfide to sulfate can occur during small-degree partial melting of the upper mantle

  18. How Taxes and Spending on Education Influence Economic Growth in Poland

    2014-09-01

    Full Text Available This paper investigates the relationship between economic growth in Poland and four types of taxes and human capital investment. We primarily rely on an exogenous growth model that merges the Mankiw-Romer-Weil model, augmented with learning-by-doing and spillover-effects, with selected elements from the literature on optimal taxation. We demonstrate that in the period 2000-2011, economic growth in Poland was primarily due to a rapid increase in the human capital stock (at a rate of 5% per annum and only secondarily due to the accumulation of productive capital (2.7% annually. Simulations of tax cuts suggest that income taxes and consumption taxes restrict economic growth equally heavily. Simultaneously reducing all tax rates by 5 percentage points (pp in Poland should increase annual GDP growth by approximately 0.4 pp. Increasing spending on education by 1 pp of GDP would increase the growth rate by approximately 0.3 pp.

    Full text: The radiocaesium in mushrooms has been monitored in Poland after the Chernobyl accident. The samples of mushrooms were collected all over the territory of Poland during the period 1986-2000. Activity of 137 Cs was much higher than in other foodstuff. This is connected with specific forest ecosystem and tendency to accumulate caesium by some kinds of mushrooms. The significant variations were observed in different species of mushrooms collected at the same area and time. This paper presents the activity of 137 Cs in Xerocomus badius, Boletus edulis and Cantharellus cibarius in Poland in 2000. The samples had been analysed during mushroom-season (June-September). Activities of 137 Cs were measured by gamma spectrometry with HPGe or NaI(Tl) detectors. The activity of 137 Cs was in range 24-472 Bq/kg for Xerocomus badius, 1-678 Bq/kg for Boletus edulis and 1-557 Bq/kg for Cantharellus cibarius. The results were compared to the data from previous years. (author)

    2015-03-01

    Full Text Available Species of the genus Orobanche (Orobanchaceae, parasitic on Centaurea in Central Europe, were previously considered to belong to the O. elatior group. At present, the taxon is differentiated into two species, O. elatior Sutton and O. kochii F.W. Schultz. The paper presents for the first time the distribution of O. elatior and O. kochii in Poland based on a critical revision of herbarium and the literature data, as well as the results of field studies conducted between 1999 and 2014. The majority of the species’ localities are in south Poland: Silesia-Cracow, Małopolska and the Lublin Uplands. The distribution of both species in Poland is mapped and chronologically organized, and is thus the most recent in Europe. The taxonomy, host preferences, and ecology are also discussed. Seeds of both species were also investigated using light and scanning electron microscopy, which resulted in the designation of diagnostic features. The new color form of O. kochii f. citrina is described and illustrated. An account of all revised herbarium specimens collected from Poland, deposited in Poland and neighboring countries, is presented.

    The T4 euthanasia programme within Nazi Germany has been well researched, but much less is known about the extermination of psychiatric patients in Nazi-occupied territories during the same period. In Poland 20,000 mentally ill patients were deliberately killed during the German occupation. This paper traces the history of one psychiatric hospital, Zofiówka, in Otwock, south-east of Warsaw. The hospital once served the Jewish population of Poland and was the largest, most prestigious neuropsychiatric centre in the country. It is now in ruins and said to be haunted by ghosts. © The Author(s) 2014.

    Membrane biofouling, resulting from biofilm formation on the membrane, has become the main obstacle hindering wider application of membrane technology. Initial biofouling proves to be crucial which involves early stages of microbial adhesion and biofilm formation. Biological control of microbial attachment seems to be a promising strategy due to its high efficiency and eco-friendliness. The present study investigated the effects of a bacterium Bacillus pumilus SW9 on controlling the initial fouling formed by four target bacterial strains which were pioneer species responsible for biofouling in membrane bioreactors, using microfiltration membranes as the abiotic surfaces. The results suggested that strain SW9 exhibited excellent antibiofilm activity by decreasing the attached biomass of target strains. The production of extracellular polysaccharides and proteins by four target strains was also reduced. A distinct improvement of permeate flux in dead-end filtration systems was achieved when introducing strain SW9 to microfiltration experiments. Scanning electron microscopy and confocal laser scanning microscopy were performed to further ascertain significant changes of the biofouling layers. A link between biofilm inhibition and initial biofouling mitigation was thus provided, suggesting an alternatively potential way to control membrane biofouling through bacterial interactions.

  4. Sulfur in serpentinized oceanic peridotites: Serpentinization processes and microbial sulfate reduction

    Science.gov (United States)

    Alt, J.C.; Shanks, Wayne C.

    1998-01-01

    The mineralogy, contents, and isotopic compositions of sulfur in oceanic serpentinites reflect variations in temperatures and fluid fluxes. Serpentinization of serpentinization of Iberian Margin peridotites occurred at low temperatures (???20??-200??C) and high water/rock ratios. Complete serpentinization and consumption of ferrous iron allowed evolution to higher fO2. Microbial reduction of seawater sulfate resulted in addition of low-??34S sulfide (-15 to -43???) and formation of higher-sulfur assemblages that include valleriite and pyrite. The high SO4/total S ratio of Hess Deep serpentinites (0.89) results in an increase of total sulfur and high ??34S of total sulfur (mean ??? 8???). In contrast, Iberian Margin serpentinites gained large amounts of 34S-poor sulfide (mean total S = 3800 ppm), and the high sulfide/total S ratio (0.61) results in a net decrease in ??34S of total sulfur (mean ??? -5???). Thus serpentinization is a net sink for seawater sulfur, but the amount fixed and its isotopic composition vary significantly. Serpentinization may result in uptake of 0.4-14 ?? 1012 g S yr-1 from the oceans, comparable to isotopic exchange in mafic rocks of seafloor hydrothermal systems and approaching global fluxes of riverine sulfate input and sedimentary sulfide output.

  5. Characteristics of large thermal energy storage systems in Poland

    2017-11-01

    In District Heating Systems (DHS) there are significant fluctuations in demand for heat by consumers during both the heating and the summer seasons. These variations are considered primarily in the 24-hour time horizon. These problems are aggravated further if the DHS is supplied by a CHP plant, because fluctuations in heat demand adversely affect to a significant degree the stable production of electricity at high overall efficiency. Therefore, introducing Thermal Energy Storage (TES) would be highly recommended on these grounds alone. The characteristics of Large (i.e. over 10 000 m3) TES in operation in Poland are presented. Information is given regarding new projects (currently in design or construction) that apply TES technology in DHS in Poland. The paper looks at the methodology used in Poland to select the TES system for a particular DHS, i.e., procedure for calculating capacity of the TES tank and the system to prevent water stored in the tank from absorbing oxygen from atmospheric air. Implementation of TES in DHS is treated as a recommended technology in the Polish District Heating sector. This technology offers great opportunities to improve the operating conditions of DHS, cutting energy production costs and emissions of pollutants to the atmosphere.

  6. The influence of educational research on education in Poland

    1981-06-01

    There is no need nowadays to convince people that modern education cannot function properly without the help of scientific research, and especially of pedagogical research. It is true that there still appear many pedagogical works `inflated by wind', as Comenius expressed it more than three hundred years ago, and these publications may even acquire a temporary popularity. But the general trend towards the development of pedagogy as a discipline based on research has been established for quite some time and is constantly gaining strength in the developed countries. Concurrently, pedagogical disciplines have had increasing influence on the development of education. The question of how these disciplines have developed in Poland and how they have influenced the educational system calls for a broader review, such as to allow one to draw conclusions on how to harmonise more effectively the domain of educational research with that of education. Such a review is the aim of the present paper. The following issues are considered: the functions of educational research, the kinds of educational investigations conducted in Poland, ways of disseminating their findings, and the organisation of research in Poland. The paper ends with a discussion of some of the more important conclusions reached.

There are over 400 museums in the country, from which 110 museums are the registered ones. The 12 national museums and 12 archaeological ones exist in major Polish cities. There are approximately 1000 excavation sites in Poland explored for 6 months in year. The archaeological research currently well developed and the X-ray radiography is widely used for investigation of excavation findings

    BACKGROUND: Perfluoroalkyl substances (PFAS) are suggested to affect human fecundity through longer time to pregnancy (TTP). We studied the relationship between four abundant PFAS and TTP in pregnant women from Greenland, Poland and Ukraine representing varying PFAS exposures and pregnancy planning...... behaviors. METHODS: We measured serum levels of perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), perfluorohexane sulfonic acid (PFHxS) and perfluorononanoic acid (PFNA) in 938 women from Greenland (448 women), Poland (203 women) and Ukraine (287 women). PFAS exposure was assessed...... weaker for women from Poland and Ukraine. PFOS, PFOA and PFHxS were not consistently associated with TTP. CONCLUSIONS: Findings do not provide consistent evidence that environmental exposure to PFAS is impairing female fecundity by delaying time taken to conceive....

    Sadkowska-Todys, Małgorzata; Czarkowski, Mirosław P

    The aim of the study is to assess the epidemiological situation of salmonellosis in Poland in 2014 in comparison to the previous years. The evaluation was based on the data from the bulletin “Infectious diseases and poisoning in Poland 2014”, information from the laboratories of sanitary-epidemiological stations and reports from the epidemiological investigations in outbreaks of salmonellosis, sent by the sanitary-epidemiological stations to the Department of Epidemiology, as well as the data from the Department of Demographic Studies of the Central Statistical Office. Cases were classified according to the definitions adopted in the UE. In 2014, a total number of 8 392 cases of salmonellosis derived from animals were reported, including 8 197 cases of intestinal salmonellosis and 195 cases of extraintestinal. The total incidence was 21.8/100 000. Almost 96% of the cases met the criteria for a confirmed case. The number of registered cases was, for the first time since many years, higher than in the previous year, but still lower than the median for 2008-2012. A very high percentage (approximately 70%) of hospitalizations remains among patients diagnosed with salmonellosis. Approximately 33% of all cases in outbreaks of salmonellosis were hospitalized. The highest incidence was among children under the age of 5 years. Salmonellosis was reported as the cause of death for 13 patients. In 2014 there were 171 outbreaks reported with Salmonella as an etiological agent. Majority of them were small outbreaks limited to the family in singular household, and the total number of cases in those outbreaks amounted to 1 229 people. In Poland the most common etiological agent of salmonellosis is (and have been for many years) S. Enteritidis. In 2014, the first time in many years, an increase was recorded in the annual number of cases of salmonellosis. A very high percentage of hospitalizations for salmonellosis cases indicates a relatively rare practice among GPs in ordering

  12. Os-Hf-Sr-Nd isotope and PGE systematics of spinel peridotite xenoliths from Tok, SE Siberian craton: Effects of pervasive metasomatism in shallow refractory mantle

    Ionov, Dmitri A.; Shirey, Steven B.; Weis, Dominique; Brügmann, Gerhard

    2006-01-01

    Os-Hf-Sr-Nd isotopes and PGE were determined in peridotite xenoliths carried to the surface by Quaternary alkali basaltic magmas in the Tokinsky Stanovik Range on the Aldan shield. These data constrain the timing and nature of partial melting and metasomatism in the lithospheric mantle beneath SE Siberian craton. The xenoliths range from the rare fertile spinel lherzolites to the more abundant, strongly metasomatised olivine-rich (70-84%) rocks. Hf-Sr-Nd isotope compositions of the xenoliths are mainly within the fields of oceanic basalts. Most metasomatised xenoliths have lower 143Nd / 144Nd and 176Hf / 177Hf and higher 87Sr / 86Sr than the host basalts indicating that the metasomatism is older and has distinct sources. A few xenoliths have elevated 176Hf / 177Hf (up to 0.2838) and plot above the Hf-Nd mantle array defined by oceanic basalts. 187Os / 188Os in the poorly metasomatised, fertile to moderately refractory (Al2O3 ≥ 1.6%) Tok peridotites range from 0.1156 to 0.1282, with oldest rhenium depletion ages being about 2 Ga. The 187Os / 188Os in these rocks show good correlations with partial melting indices (e.g. Al2O3, modal cpx); the intercept of the Al-187Os / 188Os correlation with lowest Al2O3 estimates for melting residues (∼0.3-0.5%) has a 187Os / 188Os of ∼0.109 suggesting that these peridotites may have experienced melt extraction as early as 2.8 Gy ago. 187Os / 188Os in the strongly metasomatised, olivine-rich xenoliths (0.6-1.3% Al2O3) ranges from 0.1164 to 0.1275 and shows no apparent links to modal or chemical compositions. Convex-upward REE patterns and high abundances of heavy to middle REE in these refractory rocks indicate equilibration with evolved silicate melts at high melt / rock ratios, which may have also variably elevated their 187Os / 188Os. This inference is supported by enrichments in Pd and Pt on chondrite-normalised PGE abundance patterns in some of the rocks. The melt extraction ages for the Tok suite of 2.0 to 2.8 Ga are

A study of administrative culture and decision-making processes shows the way decisions are currently made. We also propose a way to achieve more participative......Eastern European countries, such as Poland, are often used as exemplary in social capital studies. Upon entering the European Union, the low social capital level in Poland posed problems with implementing new regulations, particularly in the environmental policy field. Environmental issues often...... present a high degree of complexity – and European legislation requires multi-stakeholder involvement in decision-making processes. Thus, the dilemma: on the one hand, there is a demand to engage and consult many actors; on the other hand, low social capital contributes to an administrative culture...

  14. 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

  15. Assessment of cyanobacteria impact on bathing water quality in Poland

    Directory of Open Access Journals (Sweden)

    Krzysztof Skotak

    2012-12-01

    Full Text Available Introduction: Quality of bathing water is of key importance for bathers’ health, mainly due to the fact, that each year millions of people use bathing sites as places for recreation and sport activities. Most of the bathing sites are of adequate quality of water, but still there are cases of health risk because bathing water is polluted. One of the main health risk factor in bathing water are cyanobacteria and their blooms. Cyanobacteria are microorganisms of morphological features of bacteria and algae. They live in colonies, which in large quantities show up as streaks, dense foam on the water surface. The aim of this paper was to assess the impact of cyanobacteria blooms on health regarding bathing water quality in Poland. Materials and methods: Assessment covered all bathing sites in Poland supervised by Polish National Sanitary Inspection (PIS in the period from 2007 to 2009. The base was data collected during bathing water monitoring conducted by PIS and their formal decisions of bathing bans introduced in response to revealed bathing water pollution. Results and discussion: The results of assessment indicate, that about one-fourth of all bathing bans in Poland was due to cyanobacteria blooms. Conclusions: Every fifth bathing sites located on artificial lake or water reservoir and every tenth on the sea bathing sites were polluted. Average period of bathing ban due to cyanobacteria blooms in Poland varies. Relatively the shortest bathing bans were observed on the sea bathing sites (no longer than one week on average. Much longer were bathing bans on lakes and artificial lakes (one month on average.

    2018-02-01

    The aim of this study is to present a review based on the literature and proceedings from selected telemedicine conferences. The review was developed using the PRISMA framework. The Embase and PubMed (updated until July 13, 2015) literature databases were searched for telemedicine-related terms and Poland. The literature search identified 129 eligible articles in the databases and 85 in conference proceedings until July 2015. Articles measured as a number of contributions per year presented a similar rising, fluctuating and almost parallel pattern. Fifty-nine percent of the reviewed papers were published in impacted journals. Almost half of all publications presented original papers. The published articles concerned mostly cardiology (16%), family medicine (15%) and pathology (11%). Conference proceedings papers concerned orthopedics (29%, significantly more frequent; p < 0.001) and cardiology (14%). Scientific activity of researchers and practitioners in Poland in the field of telemedicine is not high, but it is increasing over time. There is a tendency to present the research rather in high-quality journals instead of conferences before publication. The occurrence of individual medical specialty telemedicine in Poland may reflect country-specific needs.

  18. The Roman Catholic parish in Poland as the local community

    2014-01-01

    Full Text Available In the Roman Catholic Church a parish is the smallest legal unit and it is the milieu for religious, social, and cultural activities for a group of people joined together in a geographical area. The purpose of this article is a sociological study examining the Catholic parish in Poland as a local community. Today a parish along with its community is exposed to social change and to myriad forces characteristic of the postmodern culture. In Poland two opposite forces characterize the life of a parish community: on the one side, secularization and individualization, and on the other side, socialization and evangelization. The subjective dimension of a local community, which is related to identification of people with a local parish, along with social bonds with the parish as a local community, are discussed in the first two sections of the article. In subsequent sections some issues related to common activities, membership in movements, religious communities, and Catholic associations within the parish will be presented. While the agency of people in the parish community is theoretically acknowledged, it is still not fully implemented. The discussion is based on the data obtained from major public opinion institutes in Poland.

    2007-07-01

    The paper describes the state of the art in renewable energy sources development. The obligation resulting from the membership of Poland in the European Union as well as from other international agreements in the scope of renewable energy sources development are described. The production of electricity, heat and biofuels in Poland is given and the perspectives of development of particular renewable energy sources in Poland are discussed in the view of potential reserves and other constrains. The economic aspects of renewable energy technologies are shown. The environmental pros and cons of biomass energy development are described. Arguments for development of renewable energy sources use are stated: the decrease of dependence from primary energy sources, the decrease the emission of green house gases and the recovery of agricultural regions of the country. In conclusion it is stated that the significance of renewable energy sources in Polish conditions is constrained to local societies. Their development should be adjusted to conditions predominating in a given region and that wider consumption of renewable energy sources should develop in conformity with sustainable development, so it is necessary to reach agreement between local societies, institutions dealing with environment protection and representatives of power sector.

    Lyme disease is one of the most known tick borne diseases in Poland caused by spirochetes of the genus Borrelia burgdorferi. Most cases of Lyme disease are diagnosed in the northeastern Poland and the south of Poland, in Śląskie, Małopolskie, Podkarpackie voivodeship. The aim of the study was to evaluate epidemiological data of Lyme disease in Małopolskie voivodeship and other voivodeships in Poland and frequency analysis of the Lyme disease as an occupational disease. The authors analyzed prevalence from 1998 to 2014. Incidence of the Lyme disease was evaluated through review data from „Choroby zakaźne i zatrucia” Bulletin and Lyme disease as an occupational disease obtained data from the Nofer Institute of Occupational Medicine in Łódź. It is estimated that the number of Lyme disease cases in Poland increased 18 times between 1998 and 2014 year (2,0 to 36 per 100,000 population), in the same period it was over 35 times of sudden rise in Lyme disease incidence in Małopolskie voivodeship. In years 2005-2014 the number of cases of Lyme disease as an occupational disease fluctuated with a slight upward trend both in Poland and Małopolskie voivoideship. In Poland number of reported cases is systematically increasing. Podlaskie and Warmińsko- Mazurskie voivodeships are areas of high prevalence. Exponential increase in the number of cases is observed in southern Poland, especially in Małopolskie voivodeship from 2013.

    This is the next annual analysis of the situation of infectious and parasitic diseases in Poland in 2015 within the framework of the Epidemiological Chronicle of Przegląd Epidemiologiczny - Epidemiological Review. Its purpose is to identify potential threats to the health of populations from infectious diseases occurring in Poland with reference to other parts of the globe. This paper is an introduction to more detailed studies of the epidemiological situation of selected infectious diseases and summarizes the results of the surveillance of infectious diseases in Poland in 2015. References to epidemiological situation in other countries are limited to situations that may affect current or potential occurrence of the disease in Poland. The main source of epidemiological information for this summary is the data from the reports of the State Sanitary Inspection included in the annual bulletins “Infectious Diseases and Poisonings in Poland in 2015” and “Vaccination in Poland in 2015” (1, 2). The epidemiological situation of particular diseases is further elaborated in the Epidemiological Chronicle of the same issue of the Epidemiological Review. Data on deaths are based on the presentation of the Demographic and Labor Market Department of the Central Statistical Office on deaths from infectious and parasitic diseases registered in Poland in 2015 and earlier. For a long time, the most common diseases among epidemiological surveillance it is upper respiratory tract infections classified as “influenza and suspected influenza”. In 2015, the number of cases was 3,843,438 (9 994,7 / 100,000). As to compare with the 2014’s incidence, this was an increase of 22.6%. In 2015, incidence of intestinal infections with etiology of salmonella increased by 2.8% compared to the previous year, but compared to the median of 2009-2013 was 2.5% lower. A serious epidemiological problem is a strong upward trend in nosocomial infections including infections caused by

    2016-12-01

    Full Text Available Data from a number of tourism and transport sources are used in this analysis, concentrating on Poland: the largest tour operators and areas in which air carriers are likely to have the greatest impact. The top 25 air charter carriers identified are examined closely in terms of connections, and the geographical characteristics of these links are highlighted. The research reveals substantial differences in models of air leisure traffic between Western Europe and Poland. These are of a quantitative, but also a qualitative nature, and reflect the disparate levels of affluence of societies, different mobility patterns, and various experiences, adventures and demands on the part of travellers. Overall, charter traffic in Poland is still seen to be flourishing, while that in Western Europe is in relative decline.

  7. Orchidaceae in the anthropogenic landscape of central Poland: Diversity, extinction and conservation perspectives

    2015-01-01

    Full Text Available Orchidaceae are considered one of the largest and most endangered plant families worldwide. We analyzed the status of conservation of orchid sites in Central Poland, which serves as a model area for heavily transformed environments in moderate climate. In the area under study, 26 orchid species from 54 taxa existing in Poland were reported, 17 of them with fewer than 20 localities, 59% of which have not been confirmed since 2000. Spatial analysis of all localities has shown that Central Poland exhibits considerable diversity as regards the incidence of Orchidaceae. It has been shown that contemporary protection methods have failed to prevent the demise of these species in forest, meadow and bog habitats, which incidentally comprised most of those whose localities have been unconfirmed since 2000.

    Poland appears as a new-comer in the domain of nuclear power but in fact previous projects of nuclear power plants existed but were abruptly stopped in the afterwards of Chernobyl. Today almost 90% of the electricity produced in Poland comes from the combustion of coal and lignite. In january 2009 the Polish government decided to include nuclear power in the energy mix with an aim of a 15% share of the electricity production in 2030 and with the first nuclear plant operating in 2020. The path toward this aim is marked out as following. 2009-2010: drawing up of the legal frame, creation of the nuclear safety authority, drawing up of the list of potential sites, and launching of the public debate. 2011-2013: selection of the first site, of the pool of investors, of the reactor technology and the signature of the contract for the first plant. 2014-2015: obtention of the administrative agreements, elaboration of the technical project. 2016-2020: construction of the plant. The polish public opinion favours nuclear energy and there is a kind of competition between different regions to home nuclear power plants. In 2010 Poland signed various collaboration agreements with the Usa, France and South-Korea. Polish authorities are studying the pros and cons of the EPR (EDF - Areva), ABWR (GE/Hitachi) and AP1000 (Westinghouse) reactors. (A.C.)

    Full Text Available Purpose: The purpose of this study was to present the extent to which indicators applied by logistics providers in Poland measure logistics-related processes and performance in the context of implementing the concept of management accounting in the enterprises that were researched. Methodology: The research methods used by the authors included a literature review of mainly German and Polish publications and survey research conducted in 2011–2013 among logistics enterprises in Poland. This study served as the basis for verifying four hypotheses and formulating conclusions. Findings: The main results of this study showed that management accounting systems are implemented in about half of then logistics providers in Poland covered by the survey. 75% of all enterprises conducted indicator analysis to evaluate logistics processes, costs and performance, and 90% of the indicators used by these enterprises were of a financial nature. Research limitations: The main limitation of the research was associated with conducting the survey. The low return rate of completed questionnaires did not allow for a detailed analysis of the undertaken subject to be conducted. Moreover, the research results cannot be generalized to all logistics companies in Poland. Originality: The study was the first review of the application of indicators in logistics companies in Poland in relation to the implementation of the management accounting concept. The study provides knowledge about how Polish logistics enterprises use indicators as an important management accounting instrument.

    Full Text Available ERP and CRM management information systems constitute one of the most popular IT system groups used by enterprises, not only in Poland. From the point of view of both theoreticians and practitioners of business informatics, it is important to understand the effectiveness of IT implementation projects in Poland in comparison to similar projects in other countries. The scope of this article is to present the results of research concerning the success and failure in ERP and CRM implementation projects in medium and large enterprises in Poland. The results answer the question regarding the level of effectiveness in selected IT projects consisting in standard implementation, roll-out, upgrade, vertical solution implementation and re-implementation in enterprises based in Poland between 2013 and 2016. The study analyzed 917 projects, including 747 projects in medium enterprises and 224 in large enterprises. The research shows the structure of fully successful, partially successful and completely failed projects following the classical evaluation of IT projects. Research results show that the level of effectiveness in IT projects consisting in implementations of management information systems is slightly higher in Poland than in analogous projects studied by the Standish Group. Importantly, despite technological progress and efforts of research centres, consulting companies and software producers, the effectiveness of IT project completion has not increased for over 20 years. The results may be interesting for researchers specializing in the subject of IT project completion, as well as for practitioners implementing such projects.

    2013-01-01

    Full Text Available Here, antitumor mechanism of cinnamaldehyde derivative CB-PIC was elucidated in human SW620 colon cancer cells. CB-PIC significantly exerted cytotoxicity, increased sub-G1 accumulation, and cleaved PARP with apoptotic features, while it enhanced the phosphorylation of AMPK alpha and ACC as well as activated the ERK in hypoxic SW620 cells. Furthermore, CB-PIC suppressed the expression of HIF1 alpha, Akt, and mTOR and activated the AMPK phosphorylation in hypoxic SW620 cells. Conversely, silencing of AMPKα blocked PARP cleavage and ERK activation induced by CB-PIC, while ERK inhibitor PD 98059 attenuated the phosphorylation of AMPKα in hypoxic SW620 cells, implying cross-talk between ERK and AMPKα. Furthermore, cotreatment of CB-PIC and metformin enhanced the inhibition of HIF1α and Akt/mTOR and the activation of AMPKα and pACC in hypoxic SW620 cells. In addition, CB-PIC suppressed the growth of SW620 cells inoculated in BALB/c athymic nude mice, and immunohistochemistry revealed that CB-PIC treatment attenuated the expression of Ki-67, CD34, and CAIX and increased the expression of pAMPKα in CB-PIC-treated group. Interestingly, CP-PIC showed better antitumor activity in SW620 colon cancer cells under hypoxia than under normoxia, since it may be applied to chemoresistance. Overall, our findings suggest that activation of AMPKα and ERK mediates CB-PIC-induced apoptosis in hypoxic SW620 colon cancer cells.

  19. The Characteristics of Seismogenic Zones in SW Taiwan: Implications from Studying Mechanisms of Microearthquakes

    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

    That aim of this paper is to compare trends in global, European use of coal with tendencies in Poland, one of heavy coal dependent countries. Polish power generation is unique among OECD countries, the share of both hard coal and lignite in power generation reaches 81% [1]. Climate policy of European Union is to phase out intensive greenhouse gases sectors, thus to transform Polish power generation into less carbon intensive. Although such policy is generally accepted in Poland, the paste and practically proposed regulation that excludes coal generation from capacity mechanisms, is considered as threat to energy security. Coal is the base for generation for one simple reason, abundant in European scale hard coal reserves and significant capacities in lignite. Natural gas reserves allow to supply about 1/3 of consumption, but prices and supplies dependent hitherto on contracts with GAZPROM did not allow to develop significant generation capacities. Renewable resources are limited, there is not much possibilities for hydro, wind and solar. Poland is also one of the countries of poor air quality, traditional coal based space heating systems plus obsolete car fleet generate vast emissions, especially during the winter. Only recently this became top priority of environmental authorities. This situation is subject to transformation, government, managers are aware that the role of coal needs to be decreased, but there are two main questions, the paste of transformation and the future energy mix. The paper attempts to answer the question whether the expected changes in Polish energy mix are comparable or differ from the global and European tendencies.

  1. Shale Gas in Poland: an Analysis of Tax Mechanisms and Dynamic Interactions

    2016-12-01

    Full Text Available This is a preliminary research into possible taxation mechanisms for firms that will be operating in the shale gas industry in Poland and potential market interactions between the incumbents and the entrants. The study places focus on the level of welfare and it includes a static and a dynamic analysis. The result of the former is that the lump sum tax is the first best of all considered tax mechanisms for the Polish shale gas from the welfare perspective. The second best option for taxation is a combination of the current CIT rate and a windfall profit tax. In respect to the dynamic analysis, the results suggest that Gazprom can remain the market leader in Poland even if the shale gas producers start to operate, due to the sequential character of the competition in the Polish natural gas market. Counterintuitively, it will not come at the expenses of the consumers in Poland and it can bring potential welfare gains

    Environmental deterioration in Poland particularly in 1970's, was a result of an incorrect investment policy and indifferent attitude to the principles of the preservation of nature. Water resources, as part of the environment were affected accordingly. Shortage in water resources is caused by deterioration activity of the industrial, the progressing urban development, overconsumption caused by low prices of water and low status the legislation connected with the natural environment. The European integration processes going on make it necessary to adapt the Polish standards and technological solutions in the sphere of the environmental protection to the standards required by the European Union. The destroyed natural environment cannot secure living at a relatively high standard. Hence the concept of ecological safety based on the conviction that there is no high quality J. life without a high quality of the surrounding environment' has more followers. The main purpose of this paper is to describe the nature and scope of water pollution in Poland with an emphasis on current threats to water quality, with achievements in last decade and background of other European countries.

  3. The benefits and costs of IFRS implementation in Poland – the investors’ perspective

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available A number of earlier studies analysed the process as well as the consequences of implementing Interna- tional Financial Reporting Standards (IFRS in Poland. Prior research concentrated mainly on the impact of IFRS implementation on the financial reporting of companies in Poland and market reaction to the application of IFRS. Not much attention has been given to the attitudes of different groups of accounting information users and other interested parties towards the change of reporting standards in Poland. The aim of this study is to determine how investors perceive IFRS adoption by firms in Poland. Do they see any advantages of financial statements being prepared under IFRS and not under the Polish Accounting Act after more than 10 years from the introduction of the mandatory application of IFRS for certain companies? Has the application of IFRS to the preparation of financial statements increased the scope of useful financial information for investors? Has the quality of the information presented in financial state- ments changed in any way? Finally, should the mandate to use IFRS in Poland be extended? A survey was used to obtain answers to the above questions. In the opinion of investors, the adoption of IFRS for firms has increased the comparability and usefulness of financial statements and also enhanced the pro- tection of their interests but it has not contributed to their investment decisions or the possibility to make profit forecasts. The switch to IFRS – in the perception of the respondents – failed to reduce the infor- mation asymmetry between the external and internal users of accounting information. The impact of chang- ing accounting standards on capital market liquidity failed to be unequivocally assessed.

    2013-12-01

    Full Text Available The article presents the origins and development of the idea of absenteeism in Greater Poland in the 19th century. The start date for the research is 1840, which is considered to be a breakthrough year in the history of an organized absenteeism movement in Greater Poland. It was due to the Association for the Suppression of the Use of Vodka (Towarzystwo ku Przytłumieniu Używania Wódki in the Great Duchy of Posen that was then established in Kórnik. It was a secular organization that came into being on an initiative of doctor De La Roch, who was a German surgeon of a French origin. However, as early as 1844, the idea of absenteeism raised an interest of catholic clergymen of Greater Poland with high ranking clergy such as Rev. Leon Michał Przyłuski, Archbishop of Gniezno and Rev. Jan Kanty Dąbrowski, Archbishop of Posen, and later on Archbishops Rev. Mieczysław Halka Ledóchowski and Rev. Florian Oksza Stablewski. They were fascinated with activities of Rev. Jan Nepomucen Fick, Parish Priest of Piekary Śląskie and several other priests on whose initiative a lot of church brotherhoods of so called holy continence were set up in Upper Silesia as early as the first half-year of 1844. It was due to Bishop Dąbrowski that 100 000 people took vows of absenteeism in 1844–1845, becoming members of brotherhoods of absenteeism. In turn, it was an initiative of Archbishop Przyłuski that Jesuit missionaries – Rev. Karol Bołoz Antoniewicz, Rev. Teofil Baczyński and Rev. Kamil Praszałowicz, arrived in Greater Poland from Galicia in 1852 to promote the idea of absenteeism. Starting from 1848, they were helping Silesian clergymen to spread absenteeism. Clergymen of Greater Poland were also active in secular absenteeism associations. They became involved in the workings of the Association for the Promotion of Absenteeism that was set up by Zygmunt Celichowski in Kórnik in 1887, and especially in the Jutrzenka Absenteeism Association

    1991-12-01

    The article considers trade development in major dry bulk commodities, coal, cement, iron ore and grains. Aspects covered for coal are production and exports. All coal mines in Poland are state owned. Coal production has fallen from an annual output in excess of 190 mta in the late 1980s, to under 150 mt in 1990. Output for 1991 is forecast at around 142 mt. Exports have also declined from 36 mtce in the late 1980s to an estimated 20 mt in 1991. Various factors are cited for the changing fortunes of Poland's coal industry but the most significant is the introduction of market forces to a previously centrally planned economy. Topics discussed for coal include: restructuring the coal industry for privatisation; eliminating subsidies; and export destinations. 5 tabs., 6 photos.

    2017-12-01

    The paper presents the problem of excessive air pollution in Poland caused mainly by low emission. The emission arises in result of heating flats by means of old and energetically inefficient heating installations. In Poland and Bulgaria the inhaled air is of the worst quality out of all EU countries. The paper presents economic and technical problems related to low emission occurring during the combustion of solid fuels in local boiler houses. Furthermore, the most significant economic issues, connected with the reduction of low emission are discussed, as well as technological possibilities of efficient reduction of the amount of pollution in the atmosphere. Conclusions are presented at the end of the article.

    The analyses of sulfate content, δ34S and δ18O of dissolved sulfate, and δ18O of water were carried out in a 14 km2 crystalline massif located in the Sudety Mountains (SW Poland) to 1) assess the amount of the sulfate delivered to the surface and groundwater systems by modern atmospheric precipitation, 2) determine the effect of altitude on these parameters, and 3) investigate their seasonal variations. In April and November of 2002, August 2003, and March and September of 2005, samples of water were collected from springs and streams of the massif. During these seasons, sulfate contents and δ18O(SO42−) values varied from 5.80 to 18.00 mg/l and from 3.96 to 8.23‰, respectively, showing distinctively higher values ofδ18O(SO42−) in wet seasons. The δ34S(SO42−) values had a relatively narrow range from 4.09 to 5.28‰ and were similar to those reported for organic matter in soil and the canopy throughfall in the Sudety Mountains.

    To investigate the impact of KRAS mutation variants on the activity of regorafenib in SW48 colorectal cancer cells. Activity of regorafenib was evaluated in isogenic SW48 KRAS wild-type (WT) and mutant cells. Subcutaneous xenografts (KRAS WT and G12C mutant variants) in NOD/SCID mice were analyzed to elucidate the effect of regorafenib treatment in vivo. Compared with KRAS WT cells, all mutant variants seemed associated with some degree of resistance to regorafenib-treatment in vitro. In vivo, activation of apoptosis (TUNEL) and reduction of proliferation (Ki67) after treatment with regorafenib were more pronounced in KRAS WT tumors as compared with G12C variants. In SW48 cells, exon 2 mutations of the KRAS gene may influence antitumor effects of regorafenib.

    Full Text Available The objective of the paper is to present the results of the first study of Polish startups’ ecosystem as the first stage of a larger study of digital economy landscape in Poland. The first estimate of the number of Polish startups amounts to 2400 entities. The publication presents the first survey Polish startups that marks the beginning of cyclical studies on enterprises belonging to the digital economy in Poland. The study was conducted among 423 entities using an in-house questionnaire prepared based on the author’s own knowledge. Results are discussed. Startups most often consider themselves software producers who follow the SaaS model and operate in the following industries: mobile apps, e-commerce and Internet services. Nearly one in three startups achieve 50% annual revenue growth, while in one-fifth such growth exceeds 100%. Almost two thirds of Polish startups are financed exclusively from own funds. It is necessary to repeat and deepen the study in order to determining the significance of the digital industry in the economy of Poland and the CEE region. The originality of this work lies in taking this subject for the first time in Polish literature and in elaborating the proposition of a “startup” term’s definition.

    2016-12-01

    Full Text Available Agricultural organizations play an important role in political decision-making at the local, national, and EU levels. However, it is diffi cult to estimate to what extent the size of public transfers to the Polish countryside is a direct eff ect of these organizations’ activity. The same question applies to farming privileges, which are much more numerous than those for other social groups in rural areas. One of the reasons for this stems from the fact that agricultural organizations in Poland have rarely been examined. The aim of this article is therefore to obtain a structured picture of agricultural organizations in Poland and to search for relations between their legal forms and statutory goals. The main types distinguished here include farmers’ trade unions, employers’ organizations, agribusiness organizations (agribusiness federations and unions, and associations. Taking into consideration the number of members and the thrust of activities, including impact on agricultural policy, the most important agricultural organizations in Poland seem to be the trade unions and agribusiness organizations. The substantive diff erence between them lies in their stated goals. Trade unions primarily indicate goals of a social nature. Federations of agribusiness organizations strive to support their members and promote policy changes, while agribusiness organizations work for the development of specialized farms.

    A local isolate, Aurantiochytrium sp. SW1 has been verified to have high content of docosahexanoic acid (DHA). However, the effect of different nitrogen sources on biomass, lipid concentration and DHA content in Aurantiochytrium sp. SW1 is still unknown. Hence, this study is focused in using six different organic and inorganic nitrogen sources to grow Aurantiochytrium sp. SW1 in optimized Burja medium. Monosodium glutamate (MSG) gave the highest biomass concentration of 15.97 g/L followed by ammonium nitrate (NH4NO3) with 13.37 g/L at 96 hr. These two nitrogen sources had significant effect on the biomass concentration (pDHA content in lipid showed cultivation using MSG reached 47.9% (4.95 g/L). Statistical analysis using least significant difference (LSD) showed significant lipid production (pDHA productivity (0.052 g/L hr-1) was obtained in medium containing MSG. This study proves that nitrogen component in the medium significantly affects the biomass concentration, lipid and DHA content.

    2016-06-01

    Full Text Available This paper addresses the role masculist groups currently play in fostering resistance to feminist-influenced efforts to advance the autonomy and equality of women in Poland, where the strong influence of the Polish Catholic Church continues to shape attitudes and actions in professional, governmental and civil society spheres. The paper argues that Polish public discourse since 1989 has been strongly dominated by antifeminist rhetoric advanced by masculist groups. This rhetoric is not only used in the media and in political discourse; it also influences legislation and thus hinders efforts to secure a satisfactory level of equality for women, evidenced in struggles over abortion reform, the Convention on Preventing and Combating Violence Against Women, and the trivialisation of rape. The findings of the paper are based on qualitative social research on men’s social movements in Poland between 2009 and 2012 and on qualitative media discourse analysis of articles published between 2009 and 2014.

    Depression is a serious illness affecting health, family and professional life of many people of all sectors of society. It also concerns students, regardless of their geographical location. The Beck Depression Inventory (BDI) is a proper tool to brief check of the level of depression because it has high correlation with depression. The aim of this study was to assess and compare the level of depression among medical students from Poland, Portugal and Germany. Students from different countries were asked to fill in an electronic form containing the BDI. The form was created separately for each country, using official translation of the BDI, approved by the competent psychiatric association. Google Drive software was used for the electronic form, and Stat soft Statistica v10 software for statistical analysis. There were statistically significant differences (p<0.05) in terms of average score of the BDI and of the proportion of the scores more than 10 points of medical and technology students among kinds of studies and countries. The average score of the BDI of medical students: Poland: 13.76±9.99 points; Germany: 8.49±7.64 points; Portugal: 7.37±7.67 points. The average score of the BDI of technology students: Poland: 12.42±9.66 points; Germany: 10.51±8.49 points; Portugal: 9.25±8.97 points. The proportion of the scores more than 10 points of medical students: Poland 56.32% (285/506) Germany 34.92% (154/441) Portugal 26.03% (82/315). The proportion of the scores more than 10 points of technology students: Poland 55.01% (368/669) Germany 43.82% (156/356) Portugal 37.57% (136/362). The highest depression score among medical and technology students according the BDI was found in Poland. A proper monitoring of depression is required, as well as rapid and appropriate help for those who suffer from it.

    Full Text Available Men and women wage differences is a widely discuss topic in the literature. Some authors point the fact that size of gender wage gap (GPG is not the same across wage distribution. GPG ratio is accelerating at the top of it. Thus, the main goal of presented study is to analyse impact of outliers (top earners on the values of GPG ratio and results of its decomposition. In addition we compare outcomes obtained for Spain and Poland. Elimination outliers from the sample will reduce values of men and women wage gap ratios not only in unadjusted form but in adjusted form as well. Study is based upon the Eurostat’s Structure of Earnings Survey (SES individual data in respect of 2014. In the paper we discuss results of Oaxaca-Blinder decomposition (in extension proposed by Oaxaca and Ransom obtained for Spain and Poland. Obtained results indicated two points above all. Firstly, although unadjusted GPG ratios for Spain and Poland differ significantly, the adjusted GPG ratios are at the same level (about 15%. Such situation shows the real men and women wage differences are at the same level in both countries. This is an additional indication that women situation on Polish labour market in similar to the Spanish one. Secondly, after elimination of outliers the values of GPG measures (in adjusted and unadjusted form decreased, as was expected. These falls came to approximately 3 p.p. It can be considered as significant change.

    Comprehensive epidemiologic data for multiple sclerosis (MS) in Poland are limited. The aim of this cross-sectional population-based study was to determine the incidence and prevalence of MS in the Swietokrzyskie Region (central Poland). This study identified MS cases every year between 1 January 2010 and 31 December 2014. The study area population on the prevalence day (December 31, 2014) was 1,263,176 (646,506 women and 616,670 men). A total of 1462 patients with a clinically definite diagnosis of MS according to McDonald's criteria (2005), recorded in the Polish Multiple Sclerosis Registry, were considered for estimation of crude, age- and sex-specific prevalence, and incidence. The overall crude prevalence rate of confirmed MS patients was 115.7/100,000 (95 % confidence interval (CI), 111.2-121.4). A significantly higher prevalence was recorded in females (159.6/100,000; 95 % CI, 151.1-165.3) than in males (69.7/100,000; 95 % CI, 62.4-77.3) (P < 0.001). Age-adjusted rates for the Polish and European Standard Population were 109.8/100,000 (95 % CI, 105.4-114.8) and 106.6/100,000 (95 % CI, 101.1-111.2), respectively. The female/male ratio was 2.4. The mean annual incidence was 4.2/100,000 (95 % CI. 3.7-4.4). The incidence and prevalence of MS in the Swietokrzyskie region confirm that central Poland is a high risk area for MS. Compared with previous epidemiologic studies from Poland, the prevalence of MS has increased during recent years.

    2002-08-01

    Poland depends heavily on coal to satisfy national demands for electricity. Currently, over 90% of electricity generation is produced by coal fired power plants. Because of the large dependence on coal and environmental impacts of large-scale coal combustion the country looks for a more diversified energy mix. As ways of diversification, Poland is considering the expanded role of natural gas and, potentially, nuclear power in the future energy mix. This publication describes the analysis of several diversification options for the Polish energy sector conducted by a national team in the framework of an IAEA Technical Cooperation project implemented in 1999-2000. The project provided a set of proven IAEA methodologies and tools that was utilized for a comprehensive analysis and comparison of the options including their economic competitiveness and environmental impacts. The publication is intended primarily for senior experts and technical staff in governmental organizations, research institutes, industries and utilities, who are in charge of technical analysis or decision making related to long term energy and power supply options. The report was prepared in 2001 by the staff of the Energy Market Agency (EMA, Warsaw, Poland) that was the leading Polish organization in carrying out the study

    Full Text Available The aim of this paper is to compare the tax burden on labour income in Croatia, Austria, Greece, Hungary and Poland in 2013. The Taxing Wages methodology has been applied to hypothetical units across a range of gross wages in order to calculate net average tax wedge, net average tax rate, as well as other relevant indicators. When it comes to single workers without children, the smallest tax wedge for workers earning less than the average gross wage was found in Croatia, while Poland had the smallest tax wedge for above-average wages. Due to a progressive PIT system, the tax wedge for a single worker in Croatia reaches 50% at 400% of the average gross wage, equalling that of Austria, Greece and Hungary. Tax wedges for couples with two children show a similar trend.

    Full Text Available A very significant form of company activity determining its development and even survival is innovation activity. Raising capital for the implementation of innovation is an important but not the only factor in the introduction of innovation. Characteristics of innovation, and in particular the risk of failure, make for a significant difficulty in obtaining external financing, particularly from third parties, which is an obstacle to their development and implementation. The subject of discussion in the article is the hybrid formula mezzanine type of financing innovative projects implemented both in start-up companies and in already well established companies. The purpose of the article is to discuss the possibilities and to perform an analysis of the practices followed by mezzanine funds in Poland in respect to the innovation activities of Polish companies. Research presented in the article was conducted on the basis of information on investments performed by mezzanine funds in Poland. Of particular importance for the innovativeness of the economy is to have companies from the SME sector, and therefore we also carried out research in this group. Innovations are often initiated in special purpose companies, start-up, etc., that operate in the SME sector. Therefore, the financing of innovation cannot be ignored as a thread of innovation in SMEs. The study involved interviews in several companies in the sector. The study concerned the possibilities of financing innovation involving mezzanine, knowledge of hybrid forms of financing, preparedness for hybrid financing. Studies are not representative, but are rather sounding a view to clarify any further research. Hypothesis: mezzanine financing, utilizing its specific benefits, is increasingly used to finance the gap in the financing of innovation, in particular special purpose companies in the SME sector. So the hypothesis raises two strands of research. The first concerned the financing of innovation

    2010-05-11

    The problem of the unnatural transfer of exotic ticks (Acari: Ixodida) on reptiles (Reptilia) imported to Poland is presented. In the period from 2003 to 2007, 382 specimens of reptiles belonging to the following genera were investigated: Testudo, Iguana, Varanus, Gongylophis, Python, Spalerosophis, Psammophis. The reptiles most infested with ticks are imported to Poland from Ghana in Africa, and are the commonly bred terrarium reptiles: Varanus exanthematicus and Python regius. As a result of the investigations, the transfer of exotic ticks on reptiles to Poland was confirmed. There were 2104 specimens of the genera Amblyomma and Hyalomma. The following species were found: Amblyomma exornatum Koch, 1844, Amblyomma flavomaculatum (Lucas, 1846), Amblyomma latum Koch, 1844, Amblyomma nuttalli Donitz, 1909, Amblyomma quadricavum (Schulze, 1941), Amblyomma transversale (Lucas, 1844), Amblyomma varanense (Supino, 1897), Amblyomma sp. Koch, 1844, Hyalomma aegyptium (Linnaeus, 1758). All the species of ticks of genus Amblyomma revealed have been discovered in Poland for the first time. During the research, 13 cases of anomalies of morphological structure were confirmed in the ticks A. flavomaculatum, A. latum and H. aegyptium. The expanding phenomenon of the import of exotic reptiles in Poland and Central Europe is important for parasitological and epidemiological considerations, and therefore requires monitoring and wide-ranging prophylactic activities to prevent the inflow of exotic parasites to Poland.

The aim of the study was to present the long-term variability of the start, end and duration of grass pollen seasons and the seasonal pollen index (SPI in Poland against a background of the meteorological conditions over pollen seasons. The study was performed in eight Polish cities in 1992–2014 (the common seasons were 2003–2012. Pollen season start was relatively stable in the studied period, the seasons began about the 10th of May, a bit earlier in the south part of Poland. Pollen season ends were more changeable in comparison to the season start and fluctuated from the middle of July to the middle of September. SPI clearly depended on temperature and precipitation in April–August. Daily maximum pollen concentrations were achieved between the end of May and the first decade of July and no evident relationship between this day and weather conditions was found, apart from 2004.

    Full Text Available This paper analyses the scale and sources of views on the prevalence of corruption in the education sector in Poland. Through the use of public opinion surveys, I answer questions on how the corruption level in Polish educational institutions has changed over time and how it compares to other public institutions (such as the health care sector and police and to the situation in other European countries. My goal is to investigate the effect of individual-level predictors of perceiving schools as corrupt in Poland, with special attention given to structural determinants and previous bribe-giving experiences of respondents. The results reveal that in Poland relatively few respondents have experienced recent acts of giving bribes in schools or perceive educational institutions as corrupt. However, there is a structural pattern behind the sources of negative opinions. The effect of socio-economic determinants on views relating to corruption in Polish schools is strongly pronounced and trends in the opposite direction compared to the effects reported in other European countries.

  14. Numerical modeling of convective erosion and peridotite-melt interaction in big mantle wedge: Implications for the destruction of the North China Craton

    He, Lijuan

    2014-04-01

    The deep subduction of the Pacific Plate underneath East Asia is thought to have played a key role in the destruction of the North China Craton (NCC). To test this hypothesis, this paper presents a new 2-D model that includes an initial stable equilibrated craton, the formation of a big mantle wedge (BMW), and erosion by vigorous mantle convection. The model shows that subduction alone cannot thin the cold solid craton, but it can form a low-viscosity BMW. The amount of convective erosion is directly proportional to viscosity within the BMW (η0bmw), and the rheological boundary layer thins linearly with decreasing log10(η0bmw), thereby contributing to an increase in heat flow at the lithospheric base. This model also differs from previous modeling in that the increase in heat flow decays linearly with t1/2, meaning that the overall thinning closely follows a natural log relationship over time. Nevertheless, convection alone can only cause a limited thinning due to a minor increase in basal heat flow. The lowering of melting temperature by peridotite-melt interaction can accelerate thinning during the early stages of this convection. The two combined actions can thin the craton significantly over tens of Myr. This modeling, combined with magmatism and heat flow data, indicates that the NCC evolution has involved four distinct stages: modification in the Jurassic by Pacific Plate subduction and BMW formation, destruction during the Early Cretaceous under combined convective erosion and peridotite-melt interaction, extension in the Late Cretaceous, and cooling since the late Cenozoic.

    Various conditions, including arterial hypertension, exhibit seasonal trends in their occurrence and magnitude. Those trends correspond to an interest exhibited in the number of Internet searches for the specific conditions per month. The aim of the study was to show seasonal trends in the hypertension prevalence in Poland relate to the data from the Google Trends tool. Internet search engine query data were retrieved from Google Trends from January 2008 to November 2017. Data were calculated as a monthly normalised search volume from the nine-year period. Data was presented for specific geographic regions, including Poland, the United States of America, Australia, and worldwide for the following search terms: "arterial hypertension (pol. nadciśnienie tętnicze)", "hypertension (pol. nadciśnienie)" and "hypertension medical condition". Seasonal effects were calculated using regression models and presented graphically. In Poland the search volume is the highest between November and May, while patients exhibit the least interest in arterial hypertension during summer holidays (p Google.

    Realizing scientific biomedical research conducted on human-beings demands obeying ample ethical rules. However, states keep independence in the means of implementing deontological guidelines to legislative acts. The aim of the article is to compare rules of law relative to protection of scientific biomedical research participants in two European Union member states--France and Poland. French regulations cover more types of scientific biomedical research than those in Poland. In France almost all types of interventional scientific biomedical research including research on human biological samples and research on cosmetics are covered by the rules of law. Polish regulations are limited to interventional research conducted by doctors and dentists. In both states projects of clinical trials of medicinal products demands double acceptance - from bioethics committee and from competent state authority. In protection of scientific biomedical research participants the role of state authority competent for personal data is more vital in France than it is in Poland. In France there is also National Ethics Advisory Committee whereas in Poland there is no such institution. The systems protecting scientific biomedical research participants differs therefore in both states in many vital aspects and French measures cover more types of scientific biomedical research, hence the level of participants protection in various types of research is more equitable.

  18. Herbert Hoover and the Organization of the American Relief Effort in Poland (1919-1923

    Full Text Available Poland, recreated after the armistice of 1918, was confronted at its rebirth with four very severe challenges: welding together the separate sections of the dissected country, which for many decades had been under the rule of Prussia-Germany, Austria and Russia; creating a functioning administration and military force for the country; ensuring the recovery of agriculture, which, during World War I, had seriously declined; and restarting industries destroyed or closed during foreign military occupation. Even under the valuable leadership of the first Prime Minister of the new Polish Republic Ignacy Paderewski and Marshal Jozef Pilsudski, the Poles could not accomplish the goal of rebuilding a strong Poland without outside help. The American Relief Administration (ARA, founded and led by Herbert Hoover, offered their help. The ARA, with its food aid and provision of economic assistance and expertise, played an important role in bringing about stability in the newly independent state of Poland. This paper examines the many steps Herbert Hoover had to take to arrange food relief in Poland and will outline the organization of the ARA, including the establishment of the Polish relief organization and the introduction of young Polish-American women, called the Grey Samaritans, into the field.

    Ibuprofen is a popular over-the-counter, non-steroidal anti-inflammatory medication, frequently used for the relief of fever, headaches, menstrual and other minor pains as well as a major active ingredient in numerous cold preparations. We analyzed sales volume and data obtained from the monitoring of spontaneous reports on the adverse effects of IBUM soft capsules, IBUM Forte soft capsules, and IBUM oral suspension 100 mg/5 mL collected by the manufacturer (PPF HASCO-LEK S.A. Wroclaw, Poland) and National Monitoring Center in Warszawa in the period between October 2002 and June 2012. A total of 19,644,797 units of IBUM soft capsules 200 mg, 5,678,164 units of IBUM Forte soft capsules 400 mg and 4,333,325 units of IBUM oral suspension 100 mg/5 mL (29,656,286 units altogether) produced by PPF HASCO-LEK S.A. Wrodcaw, P'oland were marketed during the period analyzed. There were 5 spontaneous reports regarding these medications registered in Poland in the period analyzed. Forms of oral ibuprofen are very safe medication rarely causing adverse effects; nevertheless, the existing spontaneous monitoring system of adverse effects in Poland is not sensitive enough to detect all adverse effects and needs improvement.

  20. Energy (in)security in Poland the case of shale gas

    The large scale extraction of natural gas from shale rock layers in North America using hydraulic fracturing, or “fracking”, has prompted geologists, economists and politicians in various parts of the world to ask whether there are new reserves of this precious resource to be found under their soils. It has also raised a host of questions about the potential environmental impacts of extracting it. Drawing on research on both sides of the Atlantic, this paper assesses the most pressing issues for research and policy makers related to shale gas extraction. The paper first provides a survey of environmental and economic issues related to shale gas. It then turns to a case study of Poland, whose policy makers have been among the most fervent proponents of shale gas development in the European Union. We examine the status of shale gas extraction in that country and what the barriers are to overcome before commercial extraction can in fact take place, if at all. - Highlights: ► We examine geologic, economic, environmental and political issues of shale gas. ► Poland is used to assess prospects for shale gas development in Europe. ► Debate in Poland has largely been framed as an energy security issue. ► A number of significant hurdles may prevent large scale development there.
