  7. Magnetic properties of cherts from the Basque-Cantabrian basin and surrounding regions: archeological implications

    Directory of Open Access Journals (Sweden)

    Full Text Available We present the first rock magnetic study of archeologically-relevant chert samples from the Basque-Cantabrian basin (BCB and surrounding regions, which was conducted in order to test the usefulness of non-destructive magnetic properties for assessing chert quality, distinguishing source areas, and identifying heated samples in the archeological record. Our results indicate that the studied BCB cherts are diamagnetic and have very low amounts of magnetic minerals. The only exception is the chert of Artxilondo, which has a mean positive magnetic susceptibility associated with larger concentrations of magnetic minerals. But even in this case, the magnetic susceptibility is within the lower range of other archeologically-relevant cherts elsewhere, which indicates that the studied BCB cherts can be considered as flint. The similar mean values for all magnetic properties, along with their associated large standard deviations, indicates that rock magnetic methods are of limited use for sourcing different types of flint except in some specific contexts involving the Artxilondo flint. With regards to the identification of chert heating in the archeological record, our results indicate only a minor magnetic enhancement of BCB natural flint samples upon heating, which we attribute to the low amount of non-silica impurities. In any case, the diamagnetic behavior of most BCB natural flints, along with the local use only of the Artxilondo type, suggests that any flint tool within the core of the BCB with positive magnetic susceptibility values is likely to have been subjected to heating for improving its knapping properties. Further studies are necessary to better identify the type, origin and grain size of magnetic minerals in BCB natural flints, and to apply non-destructive magnetic properties to flint tools in order to identify the use of heat treatment in the BCB archeological record.

    Genomic diversity based on 13 short tandem repeat (STR) loci (D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820, D16S539, TH01, TPOX, and CSF1PO) is reported for the first time in Basques from the provinces of Guipúzcoa and Navarre (Spain). STR data from previous studies on Basques from Alava and Vizcaya provinces were also examined using hierarchal analysis of molecular variance (AMOVA) and genetic admixture estimations to ascertain whether the Basques are genetically heterogeneous. To assess the genetic position of Basques in a broader geographic context, we conducted phylogenetic analyses based on F(ST) genetic distances [neighbor-joining trees and multidimensional scaling (MDS)] using data compiled in previous publications. The genetic profile of the Basque groups revealed distinctive regional partitioning of short tandem repeat (STR) diversity. Consistent with the above, native Basques clearly segregated from other populations from Europe (including Spain), North Africa, and the Middle East. The main line of genetic discontinuity inferred from the spatial variability of the microsatellite diversity in Basques significantly overlapped the geographic distribution of the Basque language. The genetic heterogeneity among native Basque groups correlates with the peculiar geography of peopling and marital structure in rural Basque zones and with language boundaries resulting from the uneven impact of Romance languages in the different Basque territories.

    Full Text Available The aim of the article. This paper attempts to examine brand loyalty among mobile phone users – the case of the main six mobile phone companies operating in the Basque region of Spain. The results of the analysis. Marketers always try to develop a strong and healthy brand in the mind of existing as well as potential consumers. There are different views regarding the meanings and measurement of brand loyalty depending on the professional backgrounds of the individuals conducting the research. More research is necessary about brand loyalty because conceptual and empirical gaps remain in the marketing literature. Competitive studies are vital considering the differences between nations' cultures, governments and economies which affect the way companies and customers respond to markets. An empirical study was conducted to collect the primary data using a questionnaire as a tool in order to test the hypotheses. The questionnaire was distributed to 400 respondents who were randomly selected from the population. Conclusions and directions of further researches. The findings proved that there is low loyalty toward phone mobile companies according to users' attitudes through: they have moderate confidence in the services of the companies, they consider themselves moderate loyal to the companies in return for the excellent service, the companies improve its services by a moderate way, promotion of competitive companies affect their attitudes, and they will not remain committed to the companies' brands, if prices increase. In addition, there is no loyalty among mobile phone users toward companies they deal with according to users' behaviors through: the respondents intend to sign out of the companies they deal with in the next few years, they will switch to competitors if they face problems regarding the companies' services, they will intend to sign up with competitors that offer better prices, they do not encourage others to sign up for these companies

    The antimicrobial activity of 19 propolis extracts prepared in different solvents (ethanol and propylene glycol) (EEP/PEP), was evaluated against some bacterial and fungal isolates using the agar-well diffusion method. It was verified that all the samples tested showed antimicrobial activity, although results varied considerably between samples. Results revealed that both types of propolis extracts showed highly sensitive antimicrobial action against Gram-positive bacteria and fungi at a concentration of 20% (Staphylococcus aureus, Streptococcus mutans, Candida albicans and Saccharomyces cerevisae) with a minimal inhibitory concentration (MIC) ranging from 0.5 to 1.5 mg/ml, with a moderate effect against Streptococcus pyogenes (MIC from 17 to 26 mg/ml). To our knowledge, this is the first study showing elevated antimicrobial activity against Gram-negative bacteria [Salmonella enterica (MIC from 0.6 to 1.4 mg/ml)] and lesser activity against Helicobacter pylori (MIC from 6 to 14 mg/ml), while Escherichia coli was resistant. This concluded that the Basque propolis had a strong and dose-dependent activity against most of the microbial strains tested, while database comparison revealed that phenolic substances were responsible for this inhibition, regardless of their geographical origin and the solvent employed for extraction. Statistical analysis showed no significant differences (P ≤ 0.05) between EEP and PEP extracts.

    The European genetic landscape has been shaped by several human migrations occurred since Paleolithic times. The accumulation of archaeological records and the concordance of different lines of genetic evidence during the last two decades have triggered an interesting debate concerning the role of ancient settlers from the Franco-Cantabrian region in the postglacial resettlement of Europe. Among the Franco-Cantabrian populations, Basques are regarded as one of the oldest and more intriguing human groups of Europe. Recent data on complete mitochondrial DNA genomes focused on macrohaplogroup R0 revealed that Basques harbor some autochthonous lineages, suggesting a genetic continuity since pre-Neolithic times. However, excluding haplogroup H, the most representative lineage of macrohaplogroup R0, the majority of maternal lineages of this area remains virtually unexplored, so that further refinement of the mtDNA phylogeny based on analyses at the highest level of resolution is crucial for a better understanding of the European prehistory. We thus explored the maternal ancestry of 548 autochthonous individuals from various Franco-Cantabrian populations and sequenced 76 mitogenomes of the most representative lineages. Interestingly, we identified three mtDNA haplogroups, U5b1f, J1c5c1 and V22, that proved to be representative of Franco-Cantabria, notably of the Basque population. The seclusion and diversity of these female genetic lineages support a local origin in the Franco-Cantabrian area during the Mesolithic of southwestern Europe, ∼10,000 years before present (YBP), with signals of expansions at ∼3,500 YBP. These findings provide robust evidence of a partial genetic continuity between contemporary autochthonous populations from the Franco-Cantabrian region, specifically the Basques, and Paleolithic/Mesolithic hunter-gatherer groups. Furthermore, our results raise the current proportion (≈15%) of the Franco-Cantabrian maternal gene pool with a putative pre

    Like other countries in the Americas, during its colonization Uruguay was the recipient of immigrants from several ethnic groups from Europe, as well as of enslaved Africans. After its independence in 1830, Basques were the first group of Europeans to arrive in the country. In this paper, we aim to contribute to the understanding of the process of integration of these migratory waves into the Uruguayan society. For that purpose, individuals of Basque origin from the city of Trinidad, Uruguay, were chosen to participate in this study. Particularly, we wanted to determine if Basque descendants in Uruguay remained relatively isolated or if they mixed with other ethnic groups. Mitochondrial DNA (mtDNA) of 60 self-identified Basque descendants, taken from a larger sample of subjects with Basque ancestors, was analyzed. The origin of mtDNA haplogroups was 77.8% European, 20.4% Amerindian, and 1.8% African, showing similar frequencies to other Uruguayan regions. Very few sequences showed a clear Basque origin, although other sources such as the Canary Islands are likely. Moreover, genetic distances clearly show that Basque descendants are genetically closer to other Uruguayan groups than to European populations, including Basques. It is possible to conclude that Basques and their descendants in the region of Trinidad did not remain isolated and that their marriage behavior was similar to that of other Uruguayan populations. However, to have a more accurate picture of the way Basques intermarried with other populations in Uruguay, new analyses are needed that take into account paternal lineages as well as biparental genetic markers.

  18. swDMR: A Sliding Window Approach to Identify Differentially Methylated Regions Based on Whole Genome Bisulfite Sequencing.

    Directory of Open Access Journals (Sweden)

    Zhen Wang

    Full Text Available DNA methylation is a widespread epigenetic modification that plays an essential role in gene expression through transcriptional regulation and chromatin remodeling. The emergence of whole genome bisulfite sequencing (WGBS represents an important milestone in the detection of DNA methylation. Characterization of differential methylated regions (DMRs is fundamental as well for further functional analysis. In this study, we present swDMR (http://sourceforge.net/projects/swDMR/ for the comprehensive analysis of DMRs from whole genome methylation profiles by a sliding window approach. It is an integrated tool designed for WGBS data, which not only implements accessible statistical methods to perform hypothesis test adapted to two or more samples without replicates, but false discovery rate was also controlled by multiple test correction. Downstream analysis tools were also provided, including cluster, annotation and visualization modules. In summary, based on WGBS data, swDMR can produce abundant information of differential methylated regions. As a convenient and flexible tool, we believe swDMR will bring us closer to unveil the potential functional regions involved in epigenetic regulation.

    The Basque Diaspora in Western USA and Argentina represents two populations which have maintained strong Basque cultural and social roots in a completely different geographic context. Hence, they provide an exceptional opportunity to study the maternal genetic legacy from the ancestral Basque population and assess the degree of genetic introgression from the host populations in two of the largest Basque communities outside the Basque Country. For this purpose, we analyzed the complete mitochondrial DNA control region of Basque descendants living in Western USA (n = 175) and in Argentina (n = 194). The Diaspora populations studied here displayed a genetic diversity in their European maternal input which was similar to that of the Basque source populations, indicating that not important founder effects would have occurred. Actually, the genetic legacy of the Basque population still prevailed in their present-day maternal pools, by means of a haplogroup distribution similar to the source population characterized by the presence of autochthonous Basque lineages, such as U5b1f1a and J1c5c1. However, introgression of non-Basque lineages, mostly Native American, has been observed in the Diaspora populations, particularly in Argentina, where the quick assimilation of the newcomers would have favored a wider admixture with host populations. In contrast, a longer isolation of the Diaspora groups in USA, because of language and cultural differences, would have limited the introgression of local lineages. This study reveals important differences in the maternal evolutionary histories of these Basque Diaspora populations, which have to be taken into consideration in forensic and medical genetic studies.

  1. A Late Variscan Sn province: the Arburese region (SW Sardinia, Italy)

    Late Variscan Sn - rich European provinces (e. g. Erzgebirge, Cornwall) are of particular relevance as they offer key insights into crustal evolution, intrusive processes and ore genesis. In Sardinia (Italy), small Sn deposits are only known in the Arburese historical mining region (SW Sardinia), hosted in low-grade metamorphics close to the contacts with intrusives. This region is characterised by two late variscan intrusions, which differ in age and composition: the Arbus and the Monte Linas pluton, aging 304 ± 1 Ma, and 289 ± 1 Ma respectively. They emplaced at shallow crustal levels and crosscut the basal thrust between the alloctonous prism and the foreland of the Variscan belt of Sardinia. The Arbus Pluton (AP) is a composite intrusion of piroxene- and amphibole- granodiorites hosting minor amounts of monzogabbroic rocks and cordierite-bearing granites with a wide core of leuco-monzogranites. Tourmaline greisens and pegmatites garnish the contact between the border facies and the host metamorphic rocks. The Monte Linas Pluton (MLP) has biotite monzogranite composition. The pluton is internally zoned, from medium grained monzogranite in the core to hololeucocratic fine-grained rock-types at the top, where often F-greisen, fayalite-pegmatite pods and sill are common. In both plutons the igneous associations are high-K ilmenite series, suggesting derivation from low- fO2 magmas possibly linked to a common crustal contribution; however, in the Linas Pluton magnetite in the fine-grained facies may indicate an increase in oxygen fugacity. The AP-related Sn ores consist of high-temperature As-Sn quartz veins. They are vertically zoned, from quartz-chlorite-cassiterite to large quartz-arsenopyrite veins. Ore microscopy and SEM-EDS analyses evidenced a vein texture made of thick idiomorphic and frequently twinned cassiterite crystals, alternated with several generations of banded/geodic quartz. Chlinoclore aggregates are included into the quartz. The arsenopyrite

    2003-12-01

    On the basis of the mineral assemblages of pelitic rocks, the Sanbagawa belt in Shikoku, SW Japan, has been divided, from low- to high-grade parts, into the chlorite, garnet, albite-biotite and oligoclase-biotite zones (Higashino, 1990). Also, the mineral assemblage of pumpellyite + actinolite + epidote + chlorite or epidote + actinolite + hematite + chlorite, which defines the pumpellyite-actinolite (PA) facies (e.g., Banno, 1998), is widely recognized in metabasites in the chlorite zone (e.g. Banno & Sakai, 1989). However, the detailed study on the PA facies regions has been done only in the Omoiji-Nagasawa area (Nakajima et al., 1977) and Asemigawa-Shirataki area (Nakajima, 1982) in central Shikoku, and thus, it is still hard to solve the regional thermal structure of the PA facies region. This study is aimed to reveal the thermal structure of the PA facies region of the Sanbagawa belt in Shikoku by analyzing the mineral assemblages and mineral chemistries of metabasites from the nine newly studied areas. The studied areas studied belong to the chlorite zone in the Oboke and Besshi units; the Oboke unit structurally underlay the Besshi unit. The mineral assemblages include pumpellyite + epidote + actinolite, epidote + actinolite _ hematite and epidote + Na-amphibole + actinolite + hematite. The metabasites from some areas involve Na-pyroxene-bearing assemblages, but the analyses of the Schreinemakers bundle of Tagiri et al. (1992) show that these assemblages do not define the Na-pyroxene-chlorite subfacies. As the low-grade metamorphic rocks do not have the hematite + pumpellyite paragenesis, its metamorphic temperature is estimated to be higher than the discontinuous reaction temperature of pumpellyite + hematite + quartz = epidote + actinolite + H2O, as shown by Nakajima et al. (1977). It is difficult to detect the difference in temperature in the PA facies regions by analyzing mineral assemblages. To detect the difference in temperature, and then to reveal

    The Lailishan deposit is an important tin deposit that is genetically associated with an Early Eocene biotite granite in the western Yunnan metallogenic belt in the Sanjiang region, SW China. This study reports new zircon U-Pb ages and Hf isotopic data, whole-rock elements, mica Ar-Ar age and C-H-O-S-Pb isotope for the Lailishan Sn deposit. The mineralization-related biotite granite crystallized during the Early Eocene (50.5 Ma), with its zircon εHf(t) values ranging from -11.5 to -7.6 and two-stage Hf model ages (TDM2) ranging from 1.60 to 1.85 Ga. The rocks are peraluminous with A/CNK values of 0.99-1.08. The granites display high Si, Al and K contents but low Mg, Fe and Ca contents. The rocks show flat chondrite-normalized REE patterns with strong Eu negative anomalies. These characteristics indicate that the magma originated from a continental crustal source. The hydrothermal muscovite exhibits an Ar-Ar plateau age of 50.4 ± 0.2 Ma. The δ18O and δD values of hydrothermal quartz from the deposit range from -7.32‰ to 4.01‰ and from -124.9‰ to -87.1‰, respectively. The δ13CPDB and δ18OSMOW values of calcite range from -11.3‰ to -3.7‰ and from +2.2‰ to +12.7‰, respectively. The sulfur isotopic compositions (δ34SV-CDT) range from +3.3‰ to +8.6‰ for sulfide separates, and the lead isotopic ratios 206Pb/204Pb, 207Pb/204Pb and 208Pb/204Pb range from 18.668 to 18.746, from 15.710 to 15.743 and from 39.202 to 39.295, respectively. These isotopic compositions are similar to those of magma-derived fluids, indicating that the ore-forming fluids and materials mainly originated from magmatic rocks with some input from meteoric water. This evidence suggests that the tin mineralization is closely linked to the Lailishan I-type granites. In combination with previous data, it is proposed in this study that widespread early Eocene magmatism resulted from the slab breakoff of the subducting Neo-Tethyan slab at ca. 55 Ma.

    The olive tree ( Olea europaea) is a predominantly Mediterranean anemophilous species. The pollen allergens from this tree are an important cause of allergic problems. Olea pollen may be relevant in relation to climate change, due to the fact that its flowering phenology is related to meteorological parameters. This study aims to investigate airborne Olea pollen data from a city on the SW Iberian Peninsula, to analyse the trends in these data and their relationships with meteorological parameters using time series analysis. Aerobiological sampling was conducted from 1994 to 2013 in Badajoz (SW Spain) using a 7-day Hirst-type volumetric sampler. The main Olea pollen season lasted an average of 34 days, from May 4th to June 7th. The model proposed to forecast airborne pollen concentrations, described by one equation. This expression is composed of two terms: the first term represents the resilience of the pollen concentration trend in the air according to the average concentration of the previous 10 days; the second term was obtained from considering the actual pollen concentration value, which is calculated based on the most representative meteorological variables multiplied by a fitting coefficient. Due to the allergenic characteristics of this pollen type, it should be necessary to forecast its short-term prevalence using a long record of data in a city with a Mediterranean climate. The model obtained provides a suitable level of confidence to forecast Olea airborne pollen concentration.

    The study deals with near 300 rain events sampled by means of a network of five automatic devices operating from January 1986 to November 1988. The results show that, on a local-scale, the rain chemistry is affected by the marine source of gases and particles. On a regional-scale, values of pH ranging from 5.5 to 4.8 are noticed. The acidity of rain has an anthropogenic origin that is mainly linked to the NO{sub 3}- content. The acidity is reinforced by air flow from continental Europe. By contrast, rain water with a basic character is related to the air fluxes from Southern Spain that increase the rain content in Ca{sup 2+}.

    It is impossible to achieve the normalization of Basque schools when they are subjected to five sets of regulations on the use of the Basque language in different parts of Euskal Herria. Instead of an education system that differentiates between various language models, what is needed is a school system that recognises the right of all Basque…

    The genetic and linguistic peculiarity of the Basque population is well known. Analysis of the studies published to date on the Basque population reveals that these studies refer basically to the provinces of Vizcaya and Labourd, both in the Northern part of the Basque Country. Multidisciplinary information indicates that the landscape differences of the Basque Country could have conditioned differential population biodynamics in the Atlantic and Mediterranean parts of the Basque area. In order to evaluate this possibility, this study focuses on the genetic constitution of the Basque population of Alava (in the South of the Basque Country) through the analysis of several red-cell systems. The data obtained in this genetic study and those from archaeology, linguistics, ethnography, and skeletal biology suggest that within the "Basque population" there may be at least two distinct groups: an "Atlantic" group and a "Mediterranean" one, divided mainly by the watershed. This geographical feature could have led to a greater genetic isolation of the Northern slopes, with the South more open to population contact. This is reflected nowadays in the different cline distribution detected for most systems in the Alava Basques in comparison with other Basque and Iberian Peninsula series studied to date.

    We examine seismotectonic setting of Biga Peninsula in western Anatolia (Çanakkale region) using the steerable filter technique and recent seismicity. One of the most important issues in geophysics is to observe borders or margins of tectonic/geologic discontinues. For this purpose, we apply this filter technique to gravity anomaly map of Biga Peninsula. We observe undetected/buried faults in Biga Peninsula using the steerable technique where they have never been seen in the geological maps before. These buried faults comply with recent seismicity for this region. Focal mechanisms of past earthquakes (M ≥ 3.5) are in good agreement with fault orientations. This observation shows that we have to take into account these fault locations and consider for preparing future seismic hazard maps. The geometry of fault segments reveals mostly strike-slip faulting regime with NE-SW trending direction of T-axis in the entire study region. According to high-resolution hypocenter relocation of the Biga earthquake sequences in the observation period between 5 January 2005 and 14 November 2015 extends from N to S direction. The stress tensor inversion results indicate a predominant normal stress regime with a NW-SE oriented maximum horizontal compressive stress (S H). According to strong discrepancy of density in the Biga Peninsula is characterized by numerous small segmented secondary faults. These buried or undetected fault locations indicate that these segments are large enough to increase earthquake stress failure towards NW-SE and N-S directions, respectively. Seismotectonic setting of Biga Peninsula is divided into sub-regions by NE-SW trending secondary faults with normal and major strike-slip components. This output is verified by steerable filter and local/regional seismotectonic analysis. We propose a new seismotectonic model for Biga Peninsula and update the orientation of active fault segments. According to our model, North Anatolian Fault Zone cross-cuts the

    In 1995, a surveillance system for prion diseases was set up in the Basque Country, an autonomous region in northern Spain (2.1 million inhabitants). In the period from January 1993 to December 2003, we diagnosed 21 patients with familial prion diseases prospectively and another 4 patients retrospectively. They represent 35% of all the cases referred to the epidemiological registry. Two main possible explanations for this unusual high incidence of familial prion diseases are proposed: first, comprehensive case ascertainment by public health neurologists; second, a probable cluster of the D178N mutation within families of Basque origin related to a still unconfirmed common ancestor. Further genetic and genealogical studies should resolve this issue.

    A new method using the inventory determined for the activity of the radionuclide {sup 137}Cs, coming from global radioactive fallout has been utilised to calculate the sedimentation rates. The method has been applied in a wide intertidal region in the Bay of Cadiz Natural Park (SW Spain). The sedimentation rates estimated by the {sup 137}Cs inventory method ranged from 0.26 cm/year to 1.72 cm/year. The average value of the sedimentation rate obtained is 0.59 cm/year, and this rate has been compared with those resulting from the application of the {sup 210}Pb dating technique. A good agreement between the two procedures has been found. From the study carried out, it has been possible for the first time, to draw a map of sedimentation rates for this zone where numerous physico-chemical, oceanographic and ecological studies converge, since it is situated in a region of great environmental interest. This area, which is representative of common environmental coastal scenarios, is particularly sensitive to perturbations related to climate change, and the results of the study will allow to make short and medium term evaluations of this change.

  13. Nature and distribution of geological domains at the Africa-Eurasia plate boundary off SW Iberia and regional geodynamic implications

    2014-05-01

    We present a new classification of geological domains at the Africa-Eurasia plate boundary off SW Iberia, together with a regional geodynamic reconstruction spanning from the Mesozoic extension to the Neogene-to-present-day convergence. It is based on seismic velocity and density models along two regional wide-angle seismic transects, one running NW-SE from the Horseshoe to the Seine abyssal plains, and the other running N-S from S Portugal to the Seine Abyssal Plain, combined with previously available information. The seismic velocity and density structure at the Seine Abyssal Plain and the internal Gulf of Cadiz indicates the presence of a highly heterogeneous oceanic crust, similar to that described in ultra-slow spreading centers, whereas in the Horseshoe and Tagus abyssal plains, the basement structure resembles that of exhumed mantle sections identified in the Northern Atlantic margin. The integration of all this new information allows defining the presence of three oceanic domains offshore SW Iberia: (1) the Seine Abyssal Plain domain, generated during the first stages of slow seafloor spreading in the NE Central Atlantic (Early Jurassic); (2) the Gulf of Cadiz domain, made of oceanic crust generated in the Alpine-Tethys spreading system between Iberia and Africa, which was coeval with the formation of the Seine Abyssal Plain domain and lasted up to the North Atlantic continental break-up (Late Jurassic); and (3) the Gorringe Bank domain, mainly made of rocks exhumed from the mantle with little synchronous magmatism, which formed during the first stages of North Atlantic opening. Our models suggest that the Seine Abyssal Plain and Gulf of Cadiz domains are separated by the Lineament South strike-slip fault, whereas the Gulf of Cadiz and Gorringe Bank domains appear to be limited by a deep thrust fault located at the center of the Horseshoe Abyssal Plain. The formation and evolution of these three domains during the Mesozoic is key to understand the sequence

  14. VS30 mapping and soil classification for seismic site effect evaluation in Dinar region, SW Turkey

    The Dinar earthquake (MS= 6.1) of 1995 October 1 killed 90 people and destroyed more than 4000 buildings. Despite the moderate size of the earthquake, the level of damage was extremely high, which led to many studies that were carried out in the region. The majority of these studies concluded that the main reasons for the damage were the construction errors and the poor soil conditions. However, at that time no appropriate soil condition map based on extended, high density measurements was available. Shear wave velocity is an important parameter for evaluating the dynamic behaviour of soil in the shallow subsurface. Thus site characterization in calculating seismic hazards is usually based on the near surface shear wave velocity values. The average shear wave velocity for the top 30 m of soil is referred to as VS30. For earthquake engineering design purposes, both the Uniform Building Code (UBC) and Eurocode 8 (EC8) codes use VS30 to classify sites according to the soil type. The Vs30 values calculated by using multichannel analysis of surface waves (MASW) were used to create a new soil classification map of the Dinar region. Surface seismic measurements were carried out at 50 locations mostly in Dinar city and its surroundings. The dispersion data of the recorded Rayleigh waves were inverted using a Genetic Algorithm (GA) method to obtain shear wave velocity profiles of the investigated sites. Thus the derived Vs30 map of the Dinar region was transformed to the UBC and EC8 standards. Soil classification results show that most parts of the region, located in alluvial basin, have low shear wave velocity values. These values are within the range of 160-240 m s-1 and thus fall into the SD and SE categories according to the UBC and the C and D categories according to EC8. Within the region, some parts located on the hill zone and the transition zone have better soil conditions [corresponding to SC (UBC) and B (EC8) categories] and have comparatively high shear wave

    Deep-sea continental slopes have valuable mineral and biological resources in close proximity to diverse, undersampled and fragile marine benthic ecosystems. The eastern Brazilian Continental Margin (19.01°S to 21.06°S, 37.88°W to 40.22°W) is an important economic region for both fishing and oil industries, but is poorly understood with respect to the structure of the soft-sediment benthic fauna, their regional distribution and their bathymetric patterns. To identify spatial and temporal patterns of benthic macrofaunal assemblages on the slope (400 to 3000 m), the Espirito Santo Basin Assessment Project (AMBES, coordinated by Cenpes-Petrobras) sampled 42 stations across the Brazilian Eastern Slope during both Summer 2012 and Winter 2013. We found a significant decrease in macrofaunal abundance at the 400 m isobath along the slope near the northern region of the Espirito Santo Basin, suggesting benthic responses to upwelling events towards the south in Campos Basin and southern Espirito Santo Basin. The taxonomic diversity and assemblage composition also changed significantly across depth zones with mid-slope peaks of diversity at 1000-1300 m. In general, macrofaunal assemblages were strongly related to slope depth, suggesting a strong influence of productivity gradients and water mass distribution on this oligotrophic margin. Sediment grain size was marginally important to macrofaunal composition on the upper slope. In general, macrofaunal assemblages on the slope of Espirito Santo Basin are similar to other areas of the SE Brazilian margin, but regional changes in response to productivity and depth need to be considered for management strategies in the face of increasing economic activities off-shore.

  16. ELECTORAL POLITICS AND CONFRONTING THE CHALLENGE OF BASQUE AND MORO NATIONALISM

    Full Text Available This article explores the similarities and differences concerning the extent to which electoral politics addresses the concerns of Basque and Moro nationalism. These demands mainly focus on the factors that have brought about their political, cultural and, for the Moros, also economic marginalization. In terms of similarities, electoral politics in the form of plebiscites and referendums are used to gauge the sentiments of the Basques and the Moros with regards to approving a national constitution with provisions affecting them as well as the establishment of an autonomous region for the Moros and the strengthening of a federal form of government in the case of the Basques. Elections are also used to choose their leaders at the local, provincial, regional and national levels. As for the differences, among the major ones are the following: One is that electoral politics in the Basque region mirrors the class divide in society and reflects the interests of the constituencies. This is not the case in Muslim Mindanao whereby patronage politics rules and electoral results are generally dictated by the Muslim elites who have close ties with the national elites. And secondly, the ideological bias of the elected leader and his political power in Spain has a direct impact on Basque nationalism. In the case of the Philippines, it is the personality of the elected leader that determines whether peace negotiations will be pursued or not. But this does not impact on national or local electoral politics as in the case of Spain.

    In the current period of the global climate change it becomes necessary to have a clear understanding of not only the changes taking place in the components of the natural environment, but also to understand development of all interactions between those components. Quaternary terrigenic sediments and lakes of the Kola Peninsula store information about the development of the region in the Late Glacial and Holocene: movements of the glacier, neotectonic activity, post-glacial rebound, formation and development of natural environments after deglaciation. Multi-proxy study of landscapes evolution of the Kola Peninsula in the Late Quaternary will help to establish a detailed reconstruction of climatic and environmental changes of this poor studied sector of the Arctic. Quaternary history on the Kola Peninsula is represented mainly by Late Pleistocene and Holocene sediments covering the Baltic Shield (Lavrova, 1960; Evzerov, 2015). Several palaeolimnological investigations in the Baltic Shield area have been performed earlier (Donner et al., 1977; Anundsen, 1985; Berglund, 2004). Studies of the southern coast of the Kola Peninsula have shown that marine transgression took place in the Late Pleistocene that was then replaced by a regression with variable speed. The slowdown of the uplift of the area took place between 8800 - 6800 BP (cal. years) and corresponded to the time of the Tapes transgression of the Arctic Ocean (Evzerov et al. 2010; Kolka, et al., 2013). Palaeoclimatic studies based on micro-paleontological analyzes indicate uneven development of the Kola Peninsula landscapes in the Late Glacial and Early Holocene. The northern coast of the Peninsula became free of ice first. In this area tundra-steppe vegetation was established for a short time and was later replaced by tundra (Snyder et al, 2000). Southern part of the Kola Peninsula was dependent on the conditions of deglaciation of the White Sea basin and cleared of ice much later (Evzerov et al., 2010; Kolka

    The Beaverhead impact structure in SW Montana and Idaho is an allochthonous fragment of a large impact structure ({approximately} 100 km diameter) that was transported some distance eastward during the Cretaceous Sevier orogeny. It is the first tectonic fragment of a large impact structure identified in the geologic record. The present evidence for impact consists of shatter cones, pseudotachylites, and planar deformation features in quartz. The age of the impact is not well constrained but is estimated to be Neoproterozoic to Cambrian (1000-500 Ma). The Beaverhead impact event must have created other features that may be preserved, elsewhere in western Montana and Idaho. These include proximal and distal ejecta (which may be misinterpreted as diamictites and/or tuff horizons) and other fragments of the crater floor containing shatter cones and pseudotachylite. A large circular gravity, magnetic and topographic anomaly, which could be the root of the impact structure, has been identified near Challis, Idaho. An enigmatic lithic tuff, identified in drill cores from the Challis area and an intraformational quartzite breccia in the Leaton Gulch area may be impact-related deposits, but no definitive evidence of shock metamorphism has been observed in these materials. The discovery of more pieces of the Beaverhead puzzle, as well as the recognition of other large impacts in the geologic record, are likely once the regional geologic community grows to accept the incidence of such events and becomes more familiar with the features of shock metamorphism in the field. To that end, the community of geologists in this area should integrate the Beaverhead structure into their research and teaching curriculum.

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

    The Laser Fluorimetry Technique has been used for the microanalysis of uranium content in drinking water samples collected from different sources like the hand pumps and natural springs of seismically active regions of Chamba and Dharamshala, Himachal Pradesh, NW-Himalayas and Bathinda and Mansa districts of SW-Punjab, state, India. The purpose of this study was to investigate the uranium concentration levels of ground water being used for drinking purposes and to determine its health effects, if any, to the local population of these regions. In the present study 47 samples of drinking water collected from different villages of the seismic active belt of Chamba and Dharamshala region of Himachal Pradesh, India have been analyzed for chemical and radiological toxicity. Uranium concentration in drinking water sample of study region ranged between 2.7 μgL{sup -1} - 53.9 μgL{sup -1} with an average value of 20.1 μgL{sup -1}. In SW-Punjab, Uranium concentration in 76 drinking water samples has been found to vary between 0.13 μgL{sup -1} and 676 μgL{sup -1} with an average of 90.2 μgL{sup -1}. Data analysis reveals that, 19% samples of NW-Himalayas water have uranium concentration higher than recommended limit of 30 μgL{sup -1} (WHO, 2011) while none of the samples exceeds the threshold of 60 μgL{sup -1} recommended by AERB, DAE, India, 2004. On the other hand, 64% water samples of SW-Punjab have uranium concentration higher than recommended limit of 30 μgL{sup -1} (WHO, 2011) while 39% water samples exceeds the threshold of 60 μgL{sup -1} recommended by AERB, DAE, India, 2004.

    In the molecular era, the study of neurogenetic disorders in relict populations provides an opportunity to discover new genes by linkage studies and to establish clearer genotype-phenotype correlations in large cohorts of individuals carrying the same mutation. The Basque people are one of the most ancient populations living in Europe and represent an excellent resource for this type of analysis in certain genetic conditions. Our objective was to describe neurogenetic disorders reported in the Basque population due to the presence of ancestral mutations or an accumulation of cases or both. We conducted a search in PubMed with the terms: Basque, neurogenetic disorders, genetic risk, and neurological disorders. We identified nine autosomal and two recessive disorders in the Basque population attributable to ancestral mutations (such as in PNRP, PARK8, FTDP-TDP43, LGMD2A, VCP, c9ORF72, and CMT4A), highly prevalent (DM1) or involving unique mutations (PARK1 or MAPT). Other genes were reported for their role as protective/risk factors in complex diseases such as multiple sclerosis, Alzheimer's disease, and Parkinson's disease. At the present time, when powerful sequencing techniques are identifying large numbers of genetic variants associated with unique phenotypes, the scrutiny of these findings in genetically homogeneous populations can help analyze genotype-phenotype correlations.

    Full Text Available Currently, almost all the territories consider the internationalisation of their enterprises as a key enabler to realize their competitiveness, welfare and regional development. However, so far, very few studies have been conducted that analyze the relationship between the internationalisation aids and the degree of internationalisation achieved by a territory. Thus, the objective of this research paper is to analyze the relationships between the internationalisation indicators and the budget expenditure devoted to internationalisation by Basque government. This requires definition of the indicators for assessing the internationalisation, which have been obtained from the Plan for Business Competitiveness 2010-2013 and the Plan for Business Internationalisation 2014-2016 elaborated by Basque Government. Moreover, in order to carry out the research study, the necessary data has been obtained from different Basque and Spanish institutions. After obtaining the data, the estimation method used has been a bivariate correlation analysis that has helped to achieve the target set in the investigation. Results shows that there is a positive relationship between the expenditure on business internationalisation and the main indicators studied, but the same is not true, however, for the degree of openness of the economy and the investment relations with foreign countries. The article provides new information on how the government of a small region, such as the Basque Country, perform in relation to the internationalisation policies.

    The Mesozoic Basque-Cantabrian basin (western Pyrenees) was inverted during the Alpine Orogeny in late Cretaceous-Eocene times. The central sector of the basin, the Basque Arc is characterized by the existence of large folds (80 km long) that outline an arc. This study focuses on the interpretation of AMS fabrics in rocks from the Biscay Synclinorium, a major fold system of the Basque Arc that verges to the NE, with sub-horizontal, N110˚ E trending axes and axial planes striking to N110˚ E and dipping steeply to the SW (Calvo-Rathert et al., 2007). The aim of this contribution is characterize the deformation around the Biscay Synclinorium. For this reason we combined fieldwork with magnetic fabric analysis of 95 cores in Upper Cretaceous sedimentary rocks of the Biscay Synclinorium. 68 cores come from the Calcareous formation (marls, sandy limestones and limestones of Cenomanian to Campanian age) that makes part of the northeastern limb of the synclinorium and the remaining 27 cores from the Detrital-calcareous flysch (a multilayer sequence with sandy limestones and marls of Maastrichtian age) that crops out in the synclinorium core (Garrote et al., 1991). In the Upper Cretaceous Calcareous formation there is a penetrative cleavage that mainly strikes to N110˚ E dipping 50˚ to 60˚ to the SW (S1). In the Detrital-calcareous flysch of the core, the best-preserved planar structure is the bedding and only locally an axial planar cleavage is observed. Intersection lineations are sub-horizontal and N110˚ E-trending. The measurements of the magnetic susceptibility provide low k values ranging between 99x10-6 and 403x10-6 SI. The anisotropy of the magnetic susceptibility, P, reaches values of 1.213, pointing to the overprinting of tectonic deformation on primary magnetic fabrics of sedimentary origin. The magnetic foliation shows a fairly uniform arrangement that is nearly coincident with the dominant planar structures of the rocks, S0 or S1in the core and the limb

  8. The SW Sex enigma

    The SW Sex stars are a class of cataclysmic variables, originally identified because they shared a number of enigmatic properties - most notably, single-peaked emission lines instead of the double-peaked lines one would expect from their high-inclination accretion discs. We present high time-resolution spectrophotometry of the eclipsing nova-like variables SW Sex and DW UMa, two of the founding members of the SW Sex class. Both systems show single-peaked Balmer and HeII 4686A emission lines that appear to originate from a region in the disc that lies close to, but downstream of, the bright spot. The emission-line light curves are consistent with the finding from X-ray and ultraviolet observations that we predominantly see the flared disc rim and the unobscured back portion of the disc in these systems. In DW UMa, the HeII 4686A emission line originates from close to the white dwarf and exhibits flaring. Such flares have been used to argue for magnetically-channelled accretion, as in the intermediate polars, b...

    The contiguous region between Guangxi, Guizhou, and Yunnan, commonly referred to as the Golden Triangle region in SW China, hosts many Carlin-type gold deposits. Previously, the ages of the gold mineralization in this region have not been well constrained due to the lack of suitable minerals for radiometric dating. This paper reports the first SIMS U-Pb age of hydrothermal rutile crystals for the Zhesang Carlin-type gold deposit in the region. The hydrothermal U-bearing rutile associated with gold-bearing sulfides in the deposit yields an U-Pb age of 213.6 ± 5.4 Ma, which is within the range of the previously reported arsenopyrite Re-Os isochron ages (204 ± 19 to 235 ± 33 Ma) for three other Carlin-type gold deposits in the region. Our new and more precise rutile U-Pb age confirms that the gold mineralization was contemporaneous with the Triassic W-Sn mineralization and associated granitic magmatism in the surrounding regions. Based on the temporal correlation, we postulate that coeval granitic plutons may be present at greater depths in the Golden Triangle region and that the formation of the Carlin-type gold deposits is probably linked to the coeval granitic magmatism in the region. This study clearly demonstrates that in situ rutile U-Pb dating is a robust tool for the geochronogical study of hydrothermal deposits that contain hydrothermal rutile.

  11. Multilingual education for European minority languages: The Basque Country and Friesland

    2011-12-01

    Over the last three decades, regional minority languages in Europe have regained increased recognition and support. Their revitalisation is partly due to their being taught in schools. Multilingualism has special characteristics for speakers of minority languages and it poses unique challenges for learning minority languages. This article looks at the cases of Basque and Frisian, comparing and contrasting their similarities and differences. The educational system in the Basque Autonomous Community underwent an important transformation, starting in 1979 from a situation where less than 5 per cent of all teachers were capable of teaching through Basque. Today this figure has changed to more than 80 per cent. An innovative approach was chosen for teaching the minority language, Basque, alongside the dominant language, Spanish, and the international language, English. The outcome is a substantial increase in the proficiency in the minority language among the younger age groups. The decline of the minority language has thus been successfully reversed and one of the major challenges now is to uphold a sustainable educational system. By contrast, the Frisian language has fared less well in the Netherlands, where developments over the last 30 years have been much slower and the results more modest. Here policy-making for education and for language is caught in a continuous debate between a weak provincial level and a powerful central state level. Overall, multilingualism as a resource for individuals is valued for "bigger" languages such as English, French and German, but not for a "small" language such as Frisian. Nevertheless, a few trilingual experiments have been carried out in some schools in Friesland in teaching Frisian, Dutch and English. These experiments may also be instructive for other cases of minority languages of a "moderate strength". In the cases of both Basque and Frisian multilingualism is generally perceived as an important resource.

The mafi c swarm comprises diabases, metadiabases and amphibolites. Metadiabases originatedfrom uralitization of diabases. These rocks have tholeiitic affi nity and predominant basaltic composition. Some samples are andesi-basalts. The ages of diabases and metabasites are 1380 ± 32 Ma and 1330 ± 120 Ma respectively. Geochemical data indicate that the compositional variation of diabases and metadiadases is due to fractional crystallization of evolved tholeiitic magmas. The origin of the basaltic magmas is related to a heterogeneous mantle source.

    Samples of foliose (Nephroma antarcticum) and fruticose (Usnea sp.) lichens were collected across a steep climatic and vegetation gradient in a remote, almost pristine region of SW Chilean Patagonia. Concentrations of major and trace elements in lichens from the rainforest were among the lowest ever reported worldwide for foliose and fruticose lichens and can be considered background levels for the region. The two lichen growth forms showed different elemental compositions mainly due to the greater capacity of foliose thalli to intercept elements from windborne and canopy-leached particles. The patterns of spatial variation in the chemical composition of lichens were effectively explained by statistical methods and reflected the different availability of wet and dry deposition along the steep climatic gradient. Baseline values established for N. antarcticum samples growing in temperate Nothofagus forests were therefore distinct from those of samples growing in more open, drier habitats. The fruticose Usnea sp. showed a higher affinity for atmophile Hg, low concentrations of lithophilic elements, and the same baseline composition whether from temperate forests or from dry, barren environments. The provided background and baseline values against which variations can be measured will be useful in the early detection of local or regional climatic and environmental change, especially in view of the planned construction of hydropower dams under the recently approved HidroAysén Project.

    Full Text Available Young Basque-speaking children produce Differential Object Marking (DOM and pre-verbal complementizers in their speech, variants argued to stem from contact with Spanish (Austin, 2006, Rodríguez-Ordóñez, 2013. In this paper, I claim that despite their contact-induced origin, these forms reflect distinct developmental tendencies on the part of the child acquiring Basque. Children's use of pre-verbal complementizers in Basque seems to be a relief strategy that bilingual children employ until they have acquired the post-verbal complementizers in Basque, which are low-frequency morphemes. In contrast, the use of DOM is present in the adult input, although children use this construction to a greater extent than adults do. Finally, I discuss the implications of these findings for the part that child learners play in advancing language change.

However, it is almost absent amongst the Basque people that live in the south western part of Europe. To explain this finding, we speculate upon the putative contribution of various evolutionary forces through which the Basque genome may have been shaped. © 2015 International Society on Thrombosis and Haemostasis.

  1. An alternative method for the estimation of sedimentation rates using radiometric measurements in an intertidal region (sw of spain)

    The techniques for the direct measurement of the sedimentation rate are reliable but slow and imprecise, given that the time intervals of measurement cannot be very long. Consequently it is an extremely laborious task to obtain a representative map of the sedimentation rates and such maps are available for very few zones. However, for most environmental studies, it is very important to know the sedimentation rates. The high degree of accuracy of the gamma spectrometric techniques together with the application of the model describes in this work, has allowed the determination of the sedimentation rates in a wide spatial area such of the Bay of Cadiz to be obtained with precision and consuming considerably less time in comparison to the traditional techniques. Even so, the experimental conditions required for the sample cores are fairly restrictive, and although the radiological method provides a quantitative advance in measurement, the experimental difficulty in the execution of the study is not greatly diminished. For this reason, a second model has been derived based on the measurement of the inventory, which offers economies in time and financial cost, and which allows the sedimentation rate in a region to be determined with satisfactory accuracy. Furthermore, it has been shown that the application of this model requires a precise determination of 137Cs inventories. The sedimentation rates estimated by the 137Cs inventory method ranged from 0.26 cm/year to 1.72 cm/year. The average value of the sedimentation rate obtained is 0.59 cm/year, and this rate has been compared with those resulting from the application of the 210Pb dating technique. A good agreement between the two procedures has been found. From the study carried out, it has been possible for the first time, to draw a map of sedimentation rates for this zone where numerous physical-chemical, oceanographic and ecological studies converge, since it is situated in a region of great environmental interest

    Individuals of Basque origin migrated in large numbers to the Western USA in the second half of the nineteenth century, and the flow continued with less intensity during the last century. The European source population, that of the Basque Country, has long been a cultural and geographical isolate. Previous studies have demonstrated that Y-STR frequencies of Basques are different from those of other Spanish and European populations [1]. The Basque diaspora in the Western USA is a recent migration, but the founder effect and the incorporation of new American Y chromosomes into the paternal genetic pool of the Basque diaspora could have influenced its genetic structure and could thus have practical implications for forensic genetics. To check for genetic substructure among the European source and Basque diaspora populations and determine the most suitable population database for the Basque diaspora in the Western USA, we have analysed the haplotype distribution of 17 Y-STRs in both populations. We have found that the Basque diaspora in the Western USA largely conserve the Y chromosome lineage characteristic of the autochthonous European Basque population with no statistically significant differences. This implies that a common 17 Y-STR Basque population database could be used to calculate identification or kinship parameters regardless of whether the Basque individuals are from the European Basque Country or from the Basque diaspora in the Western USA.

    Full Text Available The Basque Country can be said to have entered a new post-violence political scenario in 2012. In this context, a new opportunity for debating about the political status of the Country re-emerges. Electoral behavior and additional social evidence show that the accommodation of the Basque Country within the current Spanish constitutional system is far from being settled. While Catalonia claims for recognition as an independent nation, the debate about the future political relationship between the Basque Country and Spain will be a central feature during the mandate of the Basque prime minister, newly elected in 2012. However, given the different positions of the main political families of this fragmented society, the possibility for a broad agreement that could also be driven through the current constitutional system seems very remote, and major future developments in this field remain uncertain and unlikely. Such a process would face two significant obstacles. On the one hand, there is the deep political fragmentation and distrust among the main political forces in the Basque Country, whose electoral expression seems to remain significantly stable. On the other hand, there is the resistance of Spanish society to recognize or accomodate asymmetry at the constitutional level.

    For the development of early warning systems for the initiation and run-out distances of debris flows, to avoid or mitigate intolerable risks, it is necessary to assess rainfall thresholds. However one must be aware that these thresholds can change. These changes can be ascribed to environmental and climate change as well as socio-economical changes. In the Wenchuan area in the Sichuan Province, SW China, changes in thresholds are related to a depletion of source materials for these debris flows. The intensive Earthquake of 2008 in the Wenchuan area generated many co-seismic landslides, which delivered a lot of loose source material. It caused a dramatic increase in debris flow occurrences in the subsequent years. A preliminary model was designed, with entrainment processes driven by run-off water as the main triggering mechanism, to describe the relationship between rain input and debris flow run-out with the intention to assess rainfall thresholds for the start of debris flows and critical run out distances. The model was calibrated on the depositional volumes of debris flow events which occurred in individual catchments in August 2011. The calibrated model was used to construct rainfall intensity -duration threshold curves. These curves describe the thresholds for a critical run-out distance, determined by the outlet of the catchment, which was considered as the limit beyond which elements at risk situated in the main river plain are threatened. The research is focused on the change in these thresholds curves after a range of consecutive debris flow triggering rain events. It appeared that for individual catchments the rate of change of these thresholds can vary dramatically which is related to the location of available loose erodible material in the catchment. The model is also applied on a regional scale in the Jingxiu area. A method was proposed to made a general estimate of the time duration to arrive at a debris flow frequency level before the earthquake

    2013-04-01

    Full Text Available Subjective national identity has been a widely studied phenomenon, and presents several implications. Membership in a specific "imagined community" and the collective adhesion of the citizens to that community are related to many aspects: economic, cultural and political. In the case of the Basque Country, subjective national identity is normally studied and measured in relation to the Spanish one, as these identites are for some people conflicting, and for others, overlapping. The reallocation of political options and positions in the political spectrum in the Basque Country and Spain, due to the end of violence, among other elements, also has as a consequence, a reallocation regarding the identity issue. The absence of violence and violent threats in the Basque Country has put institutions and political actors in a less confrontational situation. this article argues that the intensity of the confrontation and the identity are independent elements, and as a consequence, the end of violence and the new scenario has no effect on the levels of collective Basque identity, and therefore, the levels of subjective identity remain unchanged or, at least, independent from the shifts in center-periphery relations, This article aims to present data on the levels of Basque/Spanish identity in the last years to measure how subjective national identity has evolved. We look at voting behavior, language skills, age, education level and specific attitudinal and value indicators as they correlate to subjective identity. Data and evidence on the evolution in the last decade will be provided to have a clear insight on the levels and grounds on which subjective identity in the Basque Country is supported.

    To examine the effect of perceived discrimination and self-rated health among the immigrant population in the Basque Country, Spain, and determine whether this effect varies according to region of origin, age, sex and education. Descriptive cross-sectional study. The study population included immigrants aged 18 and older residing in the Basque Country. Data from the 2014 Foreign Immigrant Population Survey (n=3,456) were used. Log-binomial regression was used to quantify the association between perceived discrimination and self-rated health before and after checking for the selected characteristics. Almost 1 in 10 immigrant adults reports perceiving discrimination. In adjusted analyses, the immigrants perceiving discrimination were almost were 1.92 more likely to rate their health as poor (prevalence ratio: 1.92; 95% CI: 1.44-2.56) than those who did not report discrimination. This association did not vary according to region of origin, age, sex or educational level. Perceived discrimination shows a consistent relationship with perceived health. Moreover, this association did not depend on the region of origin, age, sex or educational level of immigrants. These results show the need for implementing inclusive policies to eliminate individual and institutional discrimination and reduce health inequalities between the immigrant and native populations.

    Full Text Available The Administration of Justice in Spain is going through a deep modernisation process aiming both at procedural and organisational reforms. The setting up of the new Judicial Office is precisely the major change of the organisation of the Administration of Justice in the last century. In this context, there is a shift in the role played by the regional governments with responsibilities in the field of Justice, as far as these regional governments are not only collaborators of the Judiciary at domestic jurisdiction, but they also become “actors” as they have decision making powers to create, to design and to organise the common procedural services of the Judicial Office and, hence, to set up the Judicial Office in each judicial district in their territory.This text presents the context and the reasons behind the setting up of the Judicial Office as a new way of organisation of the Spanish Administration of Justice; the Judiciary in Spain and the responsibilities of the regional governments in the Administration of Justice; the meaning of the Judicial Office and its guiding principles; the role of the Basque Government in setting up the Judicial Office in the Basque Country, paying special attention to its activity in the field of standardization of processes, the quality system, and of information, communication and coordination; the results of the first Judicial Offices. Finally the paper questions whether the regional or national governments are just “collaborators” or real “actors” of the Administration of Justice at domestic jurisdiction.

    Fatal familial insomnia (FFI) and familial Creutzfeldt-Jakob disease (fCJD) are familial prion diseases with autosomal dominant inheritance of the D178N mutation. FFI has been reported in at least 27 pedigrees around the world. Twelve apparently unrelated FFI and fCJD pedigrees with the characteristic D178N mutation have been reported in the Prion Diseases Registry of the Basque Country since 1993. The high incidence of familial prion diseases in this region may reflect a unique ancestral origin of the chromosome carrying this mutation. In order to investigate this putative founder effect, we developed "happy typing", a new approach to the happy mapping method, which consists of the physical isolation of large haploid genomic DNA fragments and their analysis by the Polymerase Chain Reaction in order to perform haplotypic analysis instead of pedigree analysis. Six novel microsatellite markers, located in a 150-kb genomic segment flanking the PRNP gene were characterized for typing haploid DNA fragments of 285 kb in size. A common haplotype was found in patients from the Basque region, strongly suggesting a founder effect. We propose that "happy typing" constitutes an efficient method for determining disease-associated haplotypes, since the analysis of a single affected individual per pedigree should provide sufficient evidence.

    The expansion of a trinucleotide repeat [CGG]n located in the FMR1 X-linked gene is the main cause of fragile X syndrome, the most common form of inherited mental retardation. We have analyzed the factors known, to date, to influence the instability of the repeat in 158 normal X chromosomes from the Spanish Basque population. These factors included length of the repeat, AGG interspersion pattern, length of uninterrupted CGG and DXS548-FRAXAC1 markers associated haplotype. Previous investigations on Basques showed an absence of this disorder among mentally retarded individuals that was likely due to a low prevalence of large CGG alleles and the presence of AGG interruptions on them. The present report suggests that, although the frequency of large alleles is low and they do maintain AGG interruptions, different mutational pathways that might lead to fragile X syndrome could be occurring among Basques. These pathways mainly include alleles with internal sequences 9 + 9 + n and 9 + 12 + 9 that show fragile X associated haplotypes. Besides, the lack of the most proximal AGG interruption, proposed recently as a novel factor involved in CGG repeat instability, was highly identified among alleles with long pure CGG tracts, which showed an internal sequence n + 9. The data suggest that, despite the lower incidence of large alleles, the prevalence of potentially unstable alleles among Basques is similar to that of other Caucasian populations and that these alleles could become fragile X chromosomes.

    Context The Basque Department of Health released in 2010 the “Strategy for tackling the challenge of chronicity in the Basque Country”. One of its five priority policies is contributing to the continuity of care for chronic patients. A key strategic project is the development of new integration initiatives and pilots projects in the public Basque Health System. Five different integration projects are already in place, with the Bidasoa Integrated Healthcare Organisation as the flagship project. Aim The creation of the Bidasoa Integrated Healthcare Organisation as a public brand new organisation in January 2011 aims at integrating three primary care centres and their regional hospital of reference, covering a total population of 86,235 citizens. Case description The Bidasoa integration process is characterised by its shared leadership, with converging top-down and bottom-up initiatives, and collaboration between top-management and clinicians. The initiatives for integration are operating simultaneously at different levels: strategic (integrated strategic plan), financial (common budget and capitation payment), managerial (integrated clinical management agreements), processes (integrated care pathways, development of transitional care nursing, creation of polipathology unit), tools (stratification of the population, unification of electronic health record), and research (development of action-research pilots).

    Full Text Available The Basque Region has experienced politically-motivated violence in different forms for decades. However, public policies and legal tools utilized in addressing this violence have centered on counterterrorism strategies, while bypassing, or even covering up, the occurrence of serious human rights violations committed by, or in collusion with, State representatives. This contribution identifies different forms of politically-motivated violence that have taken place from the period of the civil war in Spain onwards, offering an up-to-date map of the most serious violations of Human Rights related to the Basque Country.Thereafter, it briefly presents the legal framework addressing human rights violations, highlighting its strengths and weaknesses. The central thesis points out that double standards are being applied when legally acknowledging victims of human rights violations resulting from political violence. It leads to victims of terrorism being adequately and fairly considered, while other victims of the State or actors connected to the State are subject to non-recognition and even discrimination.

    Full Text Available Transitional justice is often understood as a field or toolkit that facilitates the establishment of "justice" and rule of law in post-conflict societies. It is also the interdisciplinary understanding and study of that toolkit or field. This article explores to what extent transitional justice is a relevant way of understanding the transformations taking place in the Basque Country in the post-conflict situation created since the final ceasefire was declared by ETA on October 20, 2011. The article analyses different aspects of the field of transitional justice and the experience in Spain and the Basque Country. It underlines the prevalence of truth-seeking processes (over amnesia and of addressing violations and victims' suffering to conclude with the need to enhance the rule of law and traditional-individualised-justice and transitional justice.

Plant populations in fragmented and isolated locations could face problems adapting to a warming climate due to limited genetic variation and restricted migration from southern...... of firewood collection. A delayed reaction to the ending of the little ice age cannot be excluded, but seems rather unlikely considering other studies from Greenland. Effects of global warming in SW Greenland must be studied over even longer time periods than the 120 years of the current study. To answer......Arctic regions have experienced higher temperatures in recent decades, and the warming trend is projected to continue in the coming years. Arctic ecosystems are considered to be particularly vulnerable to climate change. Expansion of shrubs has been observed widely in tundra areas across the Arctic...

    This study investigates whether orthographic consistency and transparency of languages have an impact on the development of reading strategies and reading sub-skills (i.e. phonemic awareness and visual attention span) in bilingual children. We evaluated 21 French (opaque)-Basque (transparent) bilingual children and 21 Spanish (transparent)-Basque (transparent) bilingual children at Grade 2, and 16 additional children of each group at Grade 5. All of them were assessed in their common language (i.e. Basque) on tasks measuring word and pseudoword reading, phonemic awareness and visual attention span skills. The Spanish speaking groups showed better Basque pseudoword reading and better phonemic awareness abilities than their French speaking peers, but only in the most difficult conditions of the tasks. However, on the visual attention span task, the French-Basque bilinguals showed the most efficient visual processing strategies to perform the task. Therefore, learning to read in an additional language affected differently Basque literacy skills, depending on whether this additional orthography was opaque (e.g. French) or transparent (e.g. Spanish). Moreover, we showed that the most noteworthy effects of Spanish and French orthographic transparency on Basque performance were related to the size of the phonological and visual grain used to perform the tasks.

  7. The earthquakes of 29 July 2003, 12 February 2007, and 17 December 2009 in the region of Cape Saint Vincent (SW Iberia) and their relation with the 1755 Lisbon earthquake

    2013-01-01

    The Cape Saint Vincent region is of major seismological interest for its tectonic complexity and for the occurrence of the great 1755 Lisbon earthquake. No structure capable of generating such a large earthquake has yet been convincingly identified, but all authors agree that there is a possibility of a similar earthquake occurring offshore of the Cape sometime in the future. To shed some light on the region's dynamics, we here examine the mechanism of the three largest earthquakes to have occurred in the last 40 years west of the Cape - 29 July 2003 (Mw = 5.3), 12 February 2007 (Mw = 6.1), and 17 December 2009 (Mw = 5.5). By inversion of the body waves and the kinematic slip distribution, we estimated the three earthquakes to have had similar characteristics (dimensions, maximum slip, stress drop, source time function, focal depth, and rupture velocity), although there were differences in the geometry of the rupture that reflect the great seismotectonic complexity of the zone. The focal mechanisms of the 2003 and 2007 earthquakes were similar, corresponding to thrusting motion, but the 2009 earthquake had a dip-slip motion in a vertical plane. As deduced from the slip distributions, the three shocks show NE-SW rupture planes, with the energy released propagating to the NE, compatible with the regional NW-SE horizontal compression produced by the convergence of the Eurasian and African plates. Applied to the generation of the 1755 Lisbon earthquake, this direction of faulting would correspond to a complex rupture along NE-SW trending thrust faults at the Gorringe Bank, the Horseshoe Scarp, and the Marquis de Pombal Fault, with the rupture propagating to the NE towards the Portuguese coast. Such a model could explain that unusually large and tsunami-generating earthquake.

  8. Chemostratigraphy of Flood Basalts in the Garzê-Litang Region and Zongza Block:Implications for Western Extension of the Emeishan Large Igneous Province, SW China

    The Late Permian Emeishan Large Igneous Province (ELIP) is commonly regarded as being located in the western part of the Yangtze craton, SW China, with an asymmetrical shape and a small area. This area, however, is just amaximum estimation because some parts of the ELIP were not recognized or dismembered and destroyed during thebasalts in petrography and geochemistry. Flood basalts in the Sanjiangkou area are composed of the lower part of the lowTi (LT) tholeiite and the upper part of the high-Ti (HT) tholeiite, which is the same as the flood basalts on the western craton, consist of HT tholeiite only. This is the same as the flood basalts within the Yangtze craton. Therefore we argue that these contemporary basalts all originated from the Emeishan mantle plume, and the ELIP could have a significant westward extension with an outcropped area of over 500,000 km2. This new scenario shows that the LT tholeiite occurs on the westem margin of the Yangtze craton, while the HT tholeiite overlying the LT basalts occupies the whole area of the ELIP.

  9. Heavy minerals and garnet geochemistry of stream sediments and bedrocks from the Almklovdalen area, Western Gneiss Region, SW Norway: Implications for provenance analysis

    Detrital heavy minerals commonly document the geological setting in the source area, hence they are widely used in sedimentary provenance analysis. In heavy mineral studies, the 63-125 and 63-250 μm grain size fractions are most commonly used. Heavy mineral data and garnet geochemistry of stream sediments and bedrocks from the catchment area draining the Almklovdalen peridotite massif in SW Norway reveal that a wider grain size spectrum needs to be considered to avoid misleading interpretations. The Almklovdalen peridotite massif consists mainly of dunite and harzburgite, as testified by the heavy mineral suite. At the outlet of the main river, the heavy mineral spectrum is very monotonous due to dilution by a strong influx of olivine. Heavy minerals like apatite and epidote characterising the host gneisses have almost disappeared. MgO-rich almandine garnets are more frequent in the coarser grain size fractions, whereas MnO-rich almandine garnets are more frequent in the finer grain size fractions. Garnets with pyrope content exceeding 50% are only found in the 500-1000 μm grain size fraction. Therefore, the sample location and the selected grain size fraction are of paramount importance when dealing with heavy minerals and mineral geochemical data; otherwise, provenance-sensitive information may be missed.

    Full Text Available An annotated check-list of the marine benthic flora of the Spanish Basque coast, based on literature records and original data, is presented. According to the present taxonomy, the known list of algae totals 372 taxa (354 species and 18 infraspecific taxa, distributed as follows: 23 Cyanophyta, 221 Rhodophyta, 74 Heterokontophyta and 54 Chlorophyta. In addition, 16 taxa are considered as taxa inquirenda and 8 as taxa excludenda. For each taxon the vertical distribution, abundance estimation, and two first published records are given. Remarks on the most noteworthy features of the flora of the study area are included. The floristic character of Spanish Basque coast flora was compared with nearby regions applying Cheney’s ratio [(Rhodophyta+ Chlorophyta/Phaeophyta, or (R+C/P]. The resulting high value (4,09 indicates its warm-water character, which was already noted at the end of the XIX century. From a physionomical point of view, Basque benthic vegetation resembles more closely that of southern regions (S Portugal, Morocco. The warming process of waters off the Basque coast during summer up to 22 ºC is responsible for the absence or very rare occurrence of cold temperate species like large fucoids and kelps, which are common in Galicia and Brittany, and explains the abundance of numerous warm-temperate species as ceramiaceous algae.Se presenta un catálogo de la flora bentónica marina de la costa vasco-española basado en citas bibliográficas y algunos datos originales.

    Despite wild food plants' potential nutritional and economic value, their knowledge and consumption is quickly decreasing throughout the world. We examine how the consideration that a wild plant use is within the cultural tradition of a given area relates to its consumption by analysing 1) current perception and 2) past and present use of six wild plants' food-uses, of which only three are locally perceived as being part of the local tradition. Research was conducted in Gorbeialdea, an area in the Basque Country with a clearly marked Basque identity opposed to the Spanish identity. Overall, there is a clear decrease in the knowledge and consumption of the selected uses and especially of the three uses acquired from local sources (i.e., the consumption of the raw leaves of Fagus sylvatica and Rumex acetosa and of the fruits of Pyrus cordata). The trend is likely driven by the disappearance of the traditional agrarian lifestyle. Among the uses not acquired from local sources, the use recently adopted from another Basque-speaking area (i.e., macerating the fruits of Prunus spinosa to elaborate a liqueur) is now considered part of the local tradition by young generations, whereas the use acquired from southern Spanish migrants (i.e., using Laurus nobilis leaves as condiments) is not. While lifestyle changes largely explain overall trends in wild edibles consumption, other cultural aspects -in our case study the stigmatization of a given source of information associated to cultural identity- might help shape which new uses of wild plants become embedded in local traditions.

    The objective of the study was to estimate the prevalence of overweight and obesity in children and adolescents in the Basque Country, Spain. It consisted of an analysis of baseline data of the Nutrition Survey, a cross-sectional study, carried out in 2004-2005. The study population comprised child and adolescent living in the Basque Country. The analysis was carried out in a representative random sample of 1178 people aged 4-18 years. Anthropometric examinations were undertaken by trained observers using standardized methods and included measurements of weight and height. Subjects were classified into different body mass index categories, according to the International Obesity Task Force guidelines. A 5.4% of the population studied was obese; 6% of males and 4.7% of females, the highest in the 11-14 age group in boys (7.2%) and in the 4-6 age group in girls (12.5%). Overweight (22.9%) was slightly higher in girls. The highest prevalence of excess weight (overweight+obesity) was observed in girls aged 4-6 years (38.4%), decreasing with age. Subjects in the 15-18 age group rated 16.6%. Boys evidenced a higher excess weight rate in the 11-14 (32.9%) and 7-10 (32%) age groups; the lowest rate was found in the 4-6 age group. Prevalence of obesity was higher in the less privileged socio-economic strata (6.9% vs. 5.2%), for both boys and girls. However, this trend was observed only in girls for overweight (25.9% vs. 21.8%). This study shows a high prevalence of obesity and overweight in the studied population and similar to other European countries and regions.

    The mechanical behavior of the continental lithosphere for the Aegean region is one of the foremost interesting geological disputes in earth sciences. The Aegean region provides complex tectonic events which produced a strong heterogeneity in the crust (i.e. large thrusts and exhumation shear zones or extensional detachments) as such in among most continental regions. In order to investigate mechanical reasons of the ongoing lithospheric-scale extension within the region, we must tackle all of the existing kinematic and dynamic agents: (1) roll back of the subduction slab and back arc extension; (2) westward extrusion of the Anatolian micro-plate; (3) block rotations of the Aegean region and western Anatolia; and (4) transtensional transform faults. Furthermore, seismological studies, particularly earthquake source mechanisms and rupture modeling, play important roles on deciphering the ongoing deformation and seismotectonic characteristics of the region. Recently, many moderate earthquakes occurred in the Gulfs of Gökova, Kuşadası, Sıǧacık and surroundings. In the present study, we examined source mechanisms and rupture histories of those earthquakes with Mw > 5.0 in order to retrieve the geometry of active faulting, source characteristics, kinematic and dynamic source parameters and current deformations of the region by using teleseismic body-waveform inversion of long-period P- and SH-waves, and broad-band P-waveforms recorded by GDSN and FDSN stations. We also checked first motion polarities of P- waveforms recorded at regional and teleseismic stations and applied several uncertainty tests to find the error limits of minimum misfit solutions. Inversion results revealed E-W directed normal faulting mechanisms with small amount of left lateral strike slip components in the Gulf of Gökova and NE-SW oriented right lateral strike slip faulting mechanisms in the Gulf of Sıǧacık. Earthquakes mostly have N-S and NW-SE directed T- axes directions which are

    The Region of Madre de Dios-Peru, the State of Acre-Brazil, and the Department of Pando-Bolivia, known collectively as the trinational MAP Region, lies at the heart of Southwestern Amazonia. This region covers over 300,000 km2 with a population of 700,000 that ranges from urban dwellers to indigenous groups trying to avoid contact with industrial society. This region, home of incredible biological and cultural wealth, represents some of the economically poorest areas of the respective countries. It is also a site of accelerating global change in land-use, with three highways being developed for all-weather transport between central Brazil and Pacific ports. Our group has engaged in pilot experiments to provide regional societies with access to recent scientific results. Our objective is to help these societies in their quest to develop through: a) the use of GPS and satellite imagery for land use planning by small rural producers; b) municipal-level meetings in two countries to evaluate current problems and future land use along the inter-oceanic highway; c) the analysis of deforestation in the trinational river basin; d) dissemination via the media of imagery and analysis of fires during the burning season; and e) incorporation of nearby forests into the rural educational system. While most of these experiments have proven successful, they pale before the challenge of expanding them to become significant in changing land use and promoting sustainable development in this region. The multiplying factors need to be in the range of ten to a thousand times the size of the pilot experiments. Public policy and economic initiatives are crucial, but are often treated as the only means for such multiplication. The basic education system represents another, complementary multiplying factor. In the State of Acre, about a third of the population, 200,000, are in the K-12 school system and of these over 80% are in the 1- to 8-year series. Currently, we are helping local school

    Science.gov (United States)

    Barroso, N.; de Ipiña, K. López; Ezeiza, A.; Barroso, O.; Susperregi, U.

    The development of Multilingual Large Vocabulary Continuous Speech Recognition systems involves issues as: Language Identification, Acoustic-Phonetic Decoding, Language Modelling or the development of appropriated Language Resources. The interest on Multilingual Systems arouses because there are three official languages in the Basque Country (Basque, Spanish, and French), and there is much linguistic interaction among them, even if Basque has very different roots than the other two languages. This paper describes the development of a Language Identification (LID) system oriented to robust Multilingual Speech Recognition for the Basque context. The work presents hybrid strategies for LID, based on the selection of system elements by Support Vector Machines and Multilayer Perceptron classifiers and stochastic methods for speech recognition tasks (Hidden Markov Models and n-grams).

    Full Text Available The aim of the research we present in this article is to offer a general overview of the situation in the Basque Country concerning gender equality/inequality among young people. This paper is based on qualitative research conducted with young Basque people (15-30 years old. In the first part, a portrait of the young Basque population is presented with regard to formal equality and changes occurring in Spanish and Basque society over the last three decades, as well as a brief review of youth studies focusing on gender analysis. In the second part, the main results of this research are outlined, following three main lines of enquiry in relation to the maintenance or transformation of asymmetrical gender models: continuities, conflicts and ruptures.

    The marine Oligo-Miocene units of western Taurides, deposited under different tectonic regimes (in Bey Dağları platform in foreland and coeval sequences in hinterland), were studied to establish a high-resolution biostratigraphic framework. Biometric study of the full spectrum of larger foraminifera in a regional scale allowed us correlating them with the shallow benthic zonation (SBZ) system introduced by [Cahuzac, B., Poignant, A., 1997. Essai de biozonation de l'Oligo-Miocène dans les bassins européens à l'aide des grands foraminifères néritiques. Bulletin de la Société géologique de France 168, 155-169], and to determine the ages of these sites on zonal precision for the first time. In correlating these assemblages to standard shallow benthic zones, planktonic data were also used whenever possible. Taxa, classified under the genera Nummulites, Miogypsina, Miolepidocyclina, Nephrolepidina, Eulepidina, Heterostegina, Operculina and Cycloclypeus (?) and their assemblages, closely resemble to the fauna described from European basins. These groups characterize the SBZ 22B to 25 zones referring to a time interval from early Chattian to Burdigalian. However, a main gap in late Chattian (SBZ 23) and in early part of the Aquitanian (SBZ 24) is also recorded in the platform succession. In the meantime, rare Eulepidina in the Burdigalian levels suggest a clear Indo-Pacific influence. Based on the discovery of early Chattian (SBZ 22B) deposits (previously mapped under Eocene/Miocene units), the Oligo-Miocene stratigraphy of the Bey Dağları platform is also revised. A more precise chronology for regional Miocene transgression is presented based on the miogypsinid evolutionary scale.

    This thesis aims to shed light on the Basque National Liberation Movement strategy and why its armed front –ETA- decided to announce the definitive cessation of its armed activity on the 20th October 2011. Based on qualitative and quantitative analysis of interviews and document data I conclude that ETA responded rationally to a contradiction of its room for manoeuvre. Three main factors made it difficult for the Basque radical nationalist to uphold their ideological paradigm. (1) Loss ...

    Ethnobotanical relevance Medicinal and food plants in the Basque Country are an integral part of a fast changing culture. With a distinct tradition and language, this region of Europe provides an important example demonstrating the changing role of local and traditional knowledge in industrial countries. As other Mediterranean regions it preserves a rich heritage of using plants as medicine and food, offering a unique opportunity for studying the medicine food interface in an ethnopharmacological context. Therefore, the key goal of this study has been to contribute to an understanding of local and traditional plant usage, to evaluate their uses as food and medicine as well as to critically assess the role of these plants in the south of the Basque Country contributing to an understanding of how foods and medicines are used. Methods A mixed methods approach, including participant observation; open and semi structured interviews was used. Ethnobotanical field work included 183 people, ages ranged from 24 to 98 years old with a majority being between 70 and 80 years old (mean age 71) from 31 towns of three different regions. The basic interview was a one-to-one meeting, which often included field walking and collection of samples as directed by the informants. 700 voucher specimens (most of them with duplicates) were collected for the data obtained. Using SPSS version 20 the gathered information was processed and the replies of the different informants were subsequently organised in variables like medicine and food plants, part of the plants used, forms of preparations, zones preferred for collecting these plants. The data were analysed based on the frequency of records. This type of approach allows us to understand the way the informant’s categorize the species, and how these categories are distributed along the sample.

    The abundances of trace elements including Sr, Ga and rare earth elements (REE) and halogens in apatite crystals from four intermediate-felsic plutons in the Zhongdian terrane in the Sanjiang region have been determined using electron microprobe and laser ablation inductively coupled plasma mass spectrometry to evaluate the potential of apatite as a petrogenic-metallogenic indicator. The selected plutons include one that is not mineralized (the Triassic Xiuwacu pluton, or the TXWC pluton), one that hosts a porphyry-type Cu deposit (the Pulang pluton, or the PL pluton), one that hosts a porphyry-type Mo deposit (the Tongchanggou pluton, or the TCG pluton), and one that hosts a vein-type Mo deposit (the Cretaceous Xiuwacu pluton, or the CXWC pluton). Except for the CXWC pluton, the other three plutons have adakite-like trace element signatures in whole rocks. The results from this study show that REE, Sr and halogens in apatite can be used to track magma compositions, oxidation states and crystallization history. Apatite crystals from the adakite-like plutons are characterized by much higher Sr/Y and δEu than the non-adakite-type pluton. This means that apatite, which is not susceptible to alteration, is a useful tool for identifying the adakite-like plutons that no longer preserve the initial Sr/Y ratios in whole rocks due to weathering and hydrothermal alteration. Based on apatite Ga contents and δEu values, it is inferred that the parental magmas for the two adakite-like plutons containing porphyry-type Cu and Mo mineralization are more oxidized than that for the non-adakite-type pluton containing vein-type Mo mineralization. Apatite crystals from the vein-type Mo deposit have much lower Cl/F ratios than those from the porphyry-type Cu and Mo deposits. Apatite crystals from the adakite-like pluton without Cu or Mo mineralization is characterized by much lower Cl/F ratios than those from the adakite-like plutons that host the porphyry-type Cu and Mo deposits.

  12. Stabilization of pSW100 from Pantoea stewartii by the F conjugation system.

    Science.gov (United States)

    Lin, Mei-Hui; Liu, Shih-Tung

    2008-05-01

    Plasmid pSW100 is 1 of the 13 plasmids from Pantoea stewartii subsp. stewartii SW2 which has a replicon that resembles that of ColE1. This work uses a pSW100 derivative, pSW140K, to study how the pSW100 replicon is stably maintained in its hosts. Our results indicate that although pSW140K is stable in Escherichia coli HB101, the plasmid is rapidly lost in another E. coli strain, DH5alpha, indicating that the genetic background of an E. coli strain affects the stability of pSW140K. Mutagenesis of E. coli HB101 with EZ::TN revealed that mutations in traC, traF, traG, traN, and traV, which encode the components of the sex pilus assembly, reduce plasmid stability. Furthermore, this work identified that a 38-bp region located immediately upstream of the RNAII promoter is critical to the maintenance of plasmid stability in E. coli HB101. TraC binds to the region, and in addition, deleting the region destabilizes the plasmid. Furthermore, inserting this 38-bp fragment into a plasmid that contains the minimal replicon from pSW200 stabilizes the plasmid in E. coli HB101. Fluorescence in situ hybridization and immunofluorescence staining also revealed that derivatives of pSW100, pSW128A, and TraC are colocalized in cells, suggesting that pSW100 may use the sex pilus assembly as a partition apparatus to ensure the even distribution of the plasmid during cell division, which may thus maintain the plasmid's stability.

  13. Subject relative clauses are not universally easier to process: Evidence from Basque.

    Studies from many languages consistently report that subject relative clauses (SR) are easier to process than object relatives (OR). However, Hsiao and Gibson (2003) report an OR preference for Chinese, a finding that has been contested. Here we report faster OR versus SR processing in Basque, an ergative, head-final language with pre-nominal relative clauses. A self-paced reading task was used in Experiments 1 and 2, while ERPs were recorded in Experiment 3. We used relative clauses that were ambiguous between an object or subject-gap interpretation and disambiguated later in the sentence. The results of Experiments 1 and 2 showed that SR took longer to read than OR in the critical disambiguating region. In addition, Experiment 3 showed that SR produced larger amplitudes than OR in the P600 window immediately after reading the critical disambiguating word. Our results suggest that SR are not universally easier to process. They cast doubts on universal hypotheses and suggest that processing complexity may depend on language-specific aspects of grammar.

    This work was aimed to study the HIV-1 subtype B epidemics in the Basque Country, Spain. 1727 HIV-1 subtype B sequences comprising protease and reverse transcriptase (PR/RT) coding regions, sampled between 2001 and 2008, were analyzed. 156 transmission clusters were detected by means of phylogenetic analyses. Most of them comprised less than 4 individuals and, in total, they included 441 patients. Six clusters comprised 10 or more patients and were further analyzed in order to study their origin and diversification. Four clusters included men who had unprotected homosexual sex (MSM), one group was formed by intravenous drug users (IDUs), and another included both IDUs and people infected through unprotected heterosexual sex (HTs). Most of these clusters originated from the mid-1980s to the mid-1990s. Only one cluster, formed by MSM, originated after 2000. The time between infections was significantly lower in MSM groups than in those containing IDUs (P-value Country is significant. Public health control measures should be reinforced to prevent the further expansion of transmission clusters and resistant mutations occurring within them.

    Emotional creativity is defined as the ability to feel and express emotions in a new, effective and authentic way. There are currently no Basque-language self-report instruments to provide valid and reliable measures of this construct. Thus, this paper describes the process of adapting and validating the Emotional Creativity Inventory (ECI) for the Basque-speaking population. The sample was comprised of 594 higher education students (388 women and 206 men) aged between 18 and 32 years old (Mage = 20.47; SD = 2.48). The Basque version of the ECI was administered along with the TMMS-23, NEO PI-R, and PANAS. The results of exploratory and confirmatory factor analyses on the Basque ECI corroborated the original scale's three-factor structure (preparedness, novelty, and effectiveness/authenticity). Those dimensions showed acceptable indexes of internal consistency (α = .80, .83, and .83) and temporal stability (r = .70, .69, and .74). The study also provided some evidence of external validity (p emotional creativity and emotional intelligence, personality, affect, and sex. The Basque ECI can be regarded as a useful tool to evaluate perceived emotional creativity during the preparation and verification phases of the creative process.

    In this study we analyze 18 classical polymorphisms (ABO, Rh, MNSs, Lewis, P, Duffy, Kell, ADA, ESD, PGM1, PGD, AK1, ACP1, GLO1, HP, GC, TF, and PI) in over 2000 autochthonous individuals from 14 natural districts in three provinces of the Basque Country (Alava, Guipuzcoa, and Biscay). Heterogeneity analysis via the chi2 test and a calculation of F(ST) indicate that there is significant genetic heterogeneity between the Basque districts. The R matrix informs us that this heterogeneity is not significantly concentrated in a single district or in the districts of a single province, but is rather distributed among several districts belonging to the three provinces analyzed. We undertake to assess the influence of various historical, geographical, and cultural factors on the genetic structure of the Basque population. Analysis suggests that allele distribution is geographically patterned in the Basque Country. The gradient distributions observed in the case of some alleles (ABO*O, RH*cDE, RH*cde, MNS*MS, and ACP1*C) on the basis of Moran's autocorrelation coefficient I, along with the influence of the two main travel routes through the Basque Country (western route through Bilbao and eastern route through Vitoria), suggest that the gene flow tends toward the coast. As regards other factors considered (administrative division, repopulation processes, linguistic heterogeneity, and north vs. south cultural heterogeneity), we detected only a certain influence exerted by an old tribal differentiation (2000 B.P.), which would diminish with the passage of time.

    from more southerly habitats are better adapted to climatic conditions in a warmer Greenland compared with local provenances. To answer the first question historical photographs of vegetation in SW Greenland (1898–1974) were compiled. The photos were repeated in 2010 and 2011 and 64 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. The results revealed a general shrub cover increase in the whole dataset, but also in a subset...... of firewood collection. A delayed reaction to the ending of the little ice age cannot be excluded, but seems rather unlikely considering other studies from Greenland. Effects of global warming in SW Greenland must be studied over even longer time periods than the 120 years of the current study. To answer...

    Full Text Available This article, which is part of researches into the recent history of the Basque country, has as fundamental objective realize an approach to the beginnings of the Coordinadora Gesto por la Paz de Euskal Herria, pioneer in the demonstrations against the political violence in the Basque country. The research conducted mainly from newspaper sources allows us to approach the precedents and the early stages of this organization which in the 90s reached nearly 175 groups and was benchmark in social mobilization against terrorism. It is not a history of Gesto por la Paz, but is the history of how was conceived. To conclude, the importance of the social mobilizations that have had in the process towards peace in the Basque country, and the significance of these groups attempting to transmit a message of peace and connivance to transform the violent or uncivil social attitudes are highlighted herein.

  1. Impact of a self-care education programme on patients with type 2 diabetes in primary care in the Basque Country

    Science.gov (United States)

    2013-01-01

    Background Type 2 diabetes mellitus (DM2) is a disease with high prevalence and significant impact in terms of mortality and morbidity. The increased prevalence of the disease requires the implementation of new strategies to promote patient self-management. The Spanish Diabetes Self-Management Program (SDSMP) has proven to be effective in other settings. The objective of this study is to assess its effectiveness in terms of care for DM2 patients in primary care settings within the Basque Health Service – Osakidetza (Spain). Method/Design This is a randomised clinical trial in which patients diagnosed with DM2, 18–79 years of age, from four health regions within the Basque Health Service will be randomised into two groups: an intervention group, who will follow the SDSMP, and a control group, who will receive usual care in accordance with the clinical guidelines for DM2 and existing regulations in our region. The intervention consists of 2,5 hour-group sessions once a week for six weeks. The sessions cover target setting and problem solving techniques, promotion of physical exercise, basic knowledge of nutrition, proper use of medication, effective communication with relatives and health professionals, and basic knowledge about DM2 and its complications. This content is complemented by educational material: books, leaflets and CDs. The primary outcome measure will be the change in glycated haemoglobin (HbA1c), and secondary outcome measures will include changes in levels of physical activity and intake of fruit and vegetables, cardiovascular risk, quality of life, self-efficacy, number of consultations and drug prescriptions. The results will be analysed 6, 12 and 24 months after the intervention. Discussion If the intervention were to be effective, the programme should be spread to the entire diabetic population in the Basque Country and it could also be applied for other diseases.

  3. Regionalised spatiotemporal rainfall and temperature models for flood studies in the Basque Country, Spain

    Directory of Open Access Journals (Sweden)

    P. Cowpertwait

    2012-09-01

    Full Text Available A spatial-temporal point process model of rainfall is fitted to data taken from three homogeneous regions in the Basque Country, Spain. The model is the superposition of two spatial-temporal Neyman-Scott processes, in which rain cells are modelled as discs with radii that follow exponential distributions. In addition, the model includes a parameter for the radius of storm discs, so that rain only occurs when both a cell and a storm disc overlap a point. The model is fitted to data for each month, taken from each of the three homogeneous regions, using a modified method of moments procedure that ensures a smooth seasonal variation in the parameter estimates.

    Daily temperature data from twenty three sites are used to fit a stochastic temperature model. A principal component analysis of the maximum daily temperatures across the sites indicates that 92% of the variance is explained by the first component, implying that this component can be used to account for spatial variation. A harmonic equation with autoregressive error terms is fitted to the first principal component. The temperature model is obtained by regressing the maximum daily temperature on the first principal component, an indicator variable for the region, and altitude. This, together with scaling and a regression model of temperature range, enables hourly temperatures to be predicted. Rainfall is included as an explanatory variable but has only a marginal influence when predicting temperatures.

    A distributed model (TETIS; Francés et al., 2007 is calibrated for a selected catchment. Five hundred years of data are simulated using the rainfall and temperature models and used as input to the calibrated TETIS model to obtain simulated discharges to compare with observed discharges. Kolmogorov-Smirnov tests indicate that there is no significant difference in the distributions of observed and simulated maximum flows at the same sites, thus supporting the use of the

  5. Bluetongue virus serotype 1 outbreak in the Basque Country (Northern Spain 2007-2008. Data support a primary vector windborne transport.

    Directory of Open Access Journals (Sweden)

    Rodrigo García-Lastra

    Full Text Available BACKGROUND: Bluetongue (BT is a vector-borne disease of ruminants that has expanded its traditional global distribution in the last decade. Recently, BTV-1 emerged in Southern Spain and caused several outbreaks in livestock reaching the north of the country. The aim of this paper was to review the emergence of BTV-1 in the Basque Country (Northern Spain during 2007 and 2008 analyzing the possibility that infected Culicoides were introduced into Basque Country by winds from the infected areas of Southern Spain. METHODOLOGY/PRINCIPAL FINDINGS: We use a complex HYSPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectory model to draw wind roses and backward wind trajectories. The analysis of winds showed September 28 to October 2 as the only period for the introduction of infected midges in the Basque Country. These wind trajectories crossed through the areas affected by serotype 1 on those dates in the South of the Iberian Peninsula. Additionally meteorological data, including wind speed and humidity, and altitude along the trajectories showed suitable conditions for Culicoides survival and dispersion. CONCLUSIONS/SIGNIFICANCE: An active infection in medium-long distance regions, wind with suitable speed, altitude and trajectory, and appropriate weather can lead to outbreaks of BTV-1 by transport of Culicoides imicola, not only over the sea (as reported previously but also over the land. This shows that an additional factor has to be taken into account for the control of the disease which is currently essentially based on the assumption that midges will only spread the virus in a series of short hops. Moreover, the epidemiological and serological data cannot rule out the involvement of other Culicoides species in the spread of the infection, especially at a local level.

Moreover, the epidemiological and serological data cannot rule out the involvement of other Culicoides species in the spread of the infection, especially at a local level. PMID:22479628

    2016-11-15

    There is currently a consensus that sexism is one of the most important causes of intimate partner violence, but this has yet to be empirically demonstrated conclusively. The key objective of the study was to adapt Ambivalent Sexism Inventory (ASI) and to validate it to the Basque language. It also aims to analyze the prevalence of violence in dating relationships and verify if ambivalent sexism in young men and women is a valid predictor of perpetration and/or victimization in their dating relationships. Ambivalent Sexism Inventory and Dating Relationship Questionnaire were administered to 1378 undergraduate students (66% women and 45% Basque), aged between 17 and 30. The psychometric properties of the Basque and Spanish versions of the ASI are deemed to be acceptable. Sufficient guarantees are provided to be used as an instrument for measuring ambivalent sexism in adult Basque speakers. Ambivalent sexism among young men and women are both positively associated with the perpetration of violence and victimization in their dating relationships. However, ambivalent sexism or two sub-types of sexism (hostile and benevolent) are not relevant risk factors to be perpetrator or victim of violence in dating relationships, due to accounting for 3% or less of variance in dating violence.

  15. Territorial Identity and Grassroots Economic Activism: The Politicization of Farmers’ Mobilizations in the French Basque Country

    Xabier Itçaina

    2015-07-01

    Full Text Available The French Basque Country (FBC represents an emblematic case of the politicization of local development through grassroots economic activism. These mobilizations are particularly obvious in the agricultural sector. Based on a qualitative research on small farmers’ organizations and short food circuits, this article shows that Basque farmers’ mobilizations constitute a case of a dual politicization of small-scale farming and territorial identity. This process has gone through two phases: the first period (1970-2000 was characterized by the politicization of local productive systems. Throughout the decade 2000-2010, a new mode of grassroots economic activism emerged, signalled by new alliances between producers and consumers, and by an increasing ideological pluralism. Two case studies illustrate these developments. The first relates to a case of explicit politicization with the controversy around the foundation in 2005 of an alternative Basque Chamber of Agriculture. The second case study is devoted to the development of short food circuits in the FBC, considered here as a case of implicit politicization of the encounter between productive and consumption circuits. Both cases illustrate the politicization of new economic social movements, and the constant overlapping of sectoral and territorial claims in the Basque territory.

  3. A specific case in tourism marketing: Rural tourism in the Basque Country

    Directory of Open Access Journals (Sweden)

    LUCÍA MEDIANO SERRANO

    2001-12-01

    Full Text Available Rural tourism in the Basque Country, which began in 1988, is a way of tourism developed in the rural environment. It develops in agrarian exploitations, and it’s leaded by farmers, who combine their traditional activity with giving another services. Marketing application in this kind of tourism has been very limited, and it’s been directed by Autonomic Administration. Since 1999, the Basque Association of Agrarian Tourism Exploitations Owners, «Nekazalturismoa», has the challenge of impulsing this activity, in which, the consumer orientation has the priority in order to be competitive. All of that must be done respecting the social, cultural and economic environment. Also, to reach this objective, all the participants, both public and private institutions, have to work together in marketing and management subjects.

  5. Women and education. The case of the Vedrunas in the Basque Country, Nineteenth and Twentieth Century

    Directory of Open Access Journals (Sweden)

    Esther Berdote Alonso

    2016-02-01

    Full Text Available The social representation of a woman as a wife and mother in the nineteenth century determined her lack of instruction and, therefore, high rates of illiteracy among women. Despite clear legislative support, scarcity of state economic sources to support the education of girls in the nineteenth century made their access to schools difficult. This reality, coupled with other circumstances, laid the foundation for new religious teaching congregations dedicated to women’s education. This paper analyses the model of education for women provided by the Carmelite Sisters of Charity from the time of their arrival to the Basque Country (1870 until the beginning of the Second Republic (1931. The analysis focuses on three elements: the process of the new foundations, pedagogical and curricular organization of the schools, and incorporation of the Basque language into the educational process. In order to analyse the model, the researcher has consulted as a primary source the Statutes of each school, which belonged to the provincial archive of the Congregation. The research carried out suggests that the Carmelite Sisters of Charity demonstrated a high degree of adaptability to the local village communities by offering the Basque lessons in certain schools while also maintaining their core mission of Christianising and educating girls.

    We evaluated the consumption of specific medications for treating cognitive symptoms associated with AD and other types of dementia in individuals over 60 years of age between 2006 and 2011 in the Basque Country. A retrospective descriptive study was conducted. The pharmacy division of the Basque Government Department of Health provided the prescribing data for the following drugs: donepezil, rivastigmine, galantamine, and memantine. The number of defined daily doses (DDDs) and the number of DDDs per 1000 inhabitants/day (DHD) were calculated. Consumption increased by 49.72% between 2006 and 2011. There were marked differences between drugs (13.02% donepezil; 93.18% rivastigmine; 37.79% galantamine; 70.40% memantine) and Basque provinces (16.34% in Áraba; 50.49% in Bizkaia; 57.37% in Gipuzkoa). Likewise, expenditure increased from €11.5 million in 2006 to € 18.1 million in 2011. This study shows increased consumption of these drugs, although there are also marked differences by province which may be due to differences in prescribing habits. Spending for these drugs rose parallel to this increase in consumption; drug prices remained stable throughout the study period. Copyright © 2014 Sociedad Española de Neurología.

  7. Oblique collision and deformation partitioning in the SW Iberian Variscides

    2016-05-01

    Different transpressional scenarios have been proposed to relate kinematics and complex deformation patterns. We apply the most suitable of them to the Variscan orogeny in SW Iberia, which is characterized by a number of successive left-lateral transpressional structures developed in the Devonian to Carboniferous period. These structures resulted from the oblique convergence between three continental terranes (Central Iberian Zone, Ossa-Morena Zone and South Portuguese Zone), whose amalgamation gave way to both intense shearing at the suture-like contacts and transpressional deformation of the continental pieces in-between, thus showing strain partitioning in space and time. We have quantified the kinematics of the collisional convergence by using the available data on folding, shearing and faulting patterns, as well as tectonic fabrics and finite strain measurements. Given the uncertainties regarding the data and the boundary conditions modeled, our results must be considered as a semi-quantitative approximation to the issue, though very significant from a regional point of view. The total collisional convergence surpasses 1000 km, most of them corresponding to left-lateral displacement parallel to terrane boundaries. The average vector of convergence is oriented E-W (present-day coordinates), thus reasserting the left-lateral oblique collision in SW Iberia, in contrast with the dextral component that prevailed elsewhere in the Variscan orogen. This particular kinematics of SW Iberia is understood in the context of an Avalonian plate salient currently represented by the South Portuguese Zone.

    We present a 17-point map of the M17SW cloud core in the 1_{10}-1_{01} transition of ortho-water at 557 GHz obtained with the Submillimeter Wave Astronomy Satellite. Water emission was detected in 11 of the 17 observed positions. The line widths of the water emission vary between 4 and 9 km s^{-1}, and are similar to other emission lines that arise in the M17SW core. A direct comparison is made between the spatial extent of the water emission and the ^{13}CO J = 5\\to4 emission; the good agreement suggests that the water emission arises in the same warm, dense gas as the ^{13}CO emission. A spectrum of the H_2^{18}O line was also obtained at the center position of the cloud core, but no emission was detected. We estimate that the average abundance of ortho-water relative to H_2 within the M17 dense core is approximately 1x10^{-9}, 30 times smaller than the average for the Orion core. Toward the H II region/molecular cloud interface in M17SW the ortho-water abundance may be about 5 times larger than in the dens...

    In the Nova Lacerda and Conquista D'Oeste regions, Mato Grosso State, SW part of the Amazonian Craton, mafic dikes trending NNW intrude the Nova Lacerda Granite (1462{+-}12 Ma), within the Jauru Domain, in the Rondonia-San Ignacio Province (1.55 - 1.3 Ga). The mafic swarm comprises diabases, metadiabases and amphibolites. Metadiabases originated from uralitization of diabases. These rocks have tholeiitic affinity and predominant basaltic composition. Some samples are andesi-basalts. The ages of diabases and metabasites are 1380 {+-} 32 Ma and 1330 {+-} 120 Ma respectively. Geochemical data indicate that the compositional variation of diabases and metadiadases is due to fractional crystallization of evolved tholeiitic magmas. The origin of the basaltic magmas is related to a heterogeneous mantle source. (author)

  11. The future of the indigenous freshwater crayfish Austropotamobius italicus in Basque Country streams: Is it possible to survive being an inconvenient species?

    Directory of Open Access Journals (Sweden)

    L. García-Arberas

    2009-01-01

    Full Text Available The white-clawed freshwater crayfish Austropotamobius italicus is listed as “vulnerable” in the Spanish Red List of threatened species, but local legislation varies among Spanish regions. Thus, while in some places the species is classified as “in risk of extinction” and various plans of conservation and restoration have been implemented, in the Basque Country and other regions the species is not listed. The distribution of the white-clawed crayfish in the province of Biscay (Basque Country was studied from 1993 to 2007 at more than 600 sampling locations. Results show that 108 streams were inhabited by the native crayfish species A. italicus while 137 streams were inhabited by non-native signal crayfish Pacifastacus leniusculus or red-swamp crayfish Procambarus clarkii. The spread of non-native crayfish is not the only threat to the native species whose survival is also closely dependent on how watersheds are managed. Most A. italicus populations inhabit headwaters, where forestry activities are very important. The presence of native crayfish in heavily forested areas results in a conflict of interests and makes its conservation particularly difficult. We employed a SWOT analysis – an assessment and decision tool commonly used in marketing and business – to evaluate the situation of the native white-clawed crayfish in Biscay, a province characterized by very high demographic pressure. SWOT analysis has proved to be a useful diagnostic tool and can help develop better and more accurate management strategies for the conservation of native crayfish threatened by multiple stressors.

  12. 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.

  13. U-Th-Pb SHRIMP ages and oxygen isotope composition of zircon from two contrasting late Variscan granitoids, Nisa-Albuquerque batholith, SW Iberian Massif: Petrologic and regional implications

    2009-08-01

    The late Variscan Nisa-Albuquerque batholith in the SW Iberian Massif, consists of a dominant very coarse-grained porphyritic S-type monzogranite to syenogranite (Nisa monzogranite) surrounding a discontinuous central core that includes contrasting very fine-grained I-type tonalite-granodiorite (Aldeia da Mata tonalite). The batholith is located at the boundary between the Central Iberian and Ossa-Morena Zones, a complex segment of crust that was subject to both Cadomian and Variscan tectonism. Variscan zircons in the Nisa monzogranite can be broadly classified into three texturally and chemically distinct types with mutually indistinguishable SHRIMP 206Pb/ 238U ages: 1) high-U, low-Th/U (< 0.1) outermost overgrowths (307.4 ± 4.0 Ma); 2) moderate U and Th/U zircon with concentric zoning occurring both as inner overgrowths and whole grains (305.4 ± 6.2 Ma)";; and 3) texturally discordant cores (309.0 ± 4.6 Ma). Many other cores have ages in the ranges 2.56-1.85 and 0.66-0.51 Ga. The overgrowths and Variscan cores with low Th/U have uniformly high δ18O (9.5 ± 0.2‰). Variscan cores with moderate Th/U have a wide range of δ18O (6.7-10.9‰). Cores older than 500 Ma have an even wider range of composition (4.4-10.0‰). Zircon from the central Aldeia da Mata tonalite, in contrast, contains no inherited cores, has moderate to high Th/U (0.5-1.8), and is uniform in 206Pb/ 238U age (306.2 ± 3.0 Ma) and δ18O (7.4 ± 0.3‰). The zircon in the Nisa monzogranite records a history of magma genesis involving mixing between 1) a metaluminous magma progressively contaminated by a small sedimentary component, and 2) a more voluminous peraluminous magma originating from a largely metasedimentary source. The inherited zircon age pattern closely matches the age pattern of detrital zircon in early Paleozoic sediments from North Africa. The zircon in the Aldeia da Mata tonalite records nothing of the age of the magma's source rocks, but the moderately high δ18O does preclude

    Full Text Available Purpose: This research analyzes the maturity of environmental management as well as the degree of to which the Circular Economy has been implemented in Basque SMEs. Design/methodology/approach: A total of 17 case studies were carried out in industrial SMEs companies in the Basque Country. Findings: The main results show that companies are limited to complying with the law and in many cases are worried about the image of the company, although they are not committed to environmental issues. There is still a lot to do in SMEs, as they are the companies that face the biggest challenges due to a lack of resources. Originality/value: Circular Economy aims to change a linear economy into promoting sustainability of the economy while also engaging in sustainable environmental protection. This research has focused on small and medium enterprises as they represent a 99% of companies in Europe and they are the ones that have the most difficulty reaching a stage of environmental excellence due to their limited resources.

    Public healthcare in the Basque Country (Spain) faces high rates of ageing and chronicity, which stress the sustainability of the system. In response to this situation, the Basque Chronicity Strategy was launched in 2010. This large-scale and far-reaching transformation initiative focused on changing the healthcare provision model towards integrated care of chronicity. Developed in the context of economic and financial crisis, strong political opposition and resistance or passivity of many relevant stakeholders, the design and implementation of the Strategy introduced some noteworthy elements, such as: a narrative of change different to the austerity discourse, which was the dominant narrative at that time; a strategic approach supported by an evidence base and solid theoretical references; and an implementation strategy that favoured local innovation and the "bottom up" approach. In spite of this, it was not possible to overcome the political barriers or bureaucratic immobility, which limited the implementation and scope of the changes, especially those related to the scalability of successful local innovations. However, some changes in the healthcare integration culture at clinical and managerial level have been introduced as a result of the Strategy, as well as organisational progression towards a chronicity-targeted healthcare model.

  17. Wind farms and mires in the Basque Country and north-west Navarra, Spain

    Full Text Available Mires occur in the Basque Country and north-west Navarra (northern Spain due to the Atlantic influence on climate. They are most frequent in the north and become rarer to the south. True peatland is found at only six locations, but there are also some para-peaty habitats associated with springs and flushes which have very thin discontinuous peat layers. Although small, this mire territory straddles the boundary between two separate autonomous communities where different regulations and management guidelines apply. Both communities have developed extensive plans to exploit wind energy, and the summit ridges of many of the mountain ranges now carry long strings of turbines. Consequences for the Basque and Navarran mire ecosystems are reviewed. Because little is known about these habitats, they went largely unnoticed during the process of wind farm planning and were thus exposed to enormous risk. Nonetheless, the impacts of development so far have been limited by careful practice combined with the fact that the locations of most of the mires do not coincide exactly with the favoured locations for wind turbines. The only blanket bog is situated in the Zalama area, where plans to build a wind farm have been abandoned for a combination of reasons. Paradoxically, the wind farm planning process was instrumental in raising social and political awareness of this important peatland, leading to a very promising level of interest in its conservation and restoration amongst local institutions.

  18. [History of biological anthropology of the Basque population: empiricism with molecular genetics].

    2008-01-01

    For decades, biological and cultural pecularities of the Basques represent major points of interest for scholars. Studies on biological anthropology began in the mid XIXth century with anthropometry and craniology. From the 1930's, hemotypology revealed characteristics (ABO and Rhesus groups) existing also within the surrounding zones of the North-Western Pyrenees (Gascony) which seem to share the same toponymic elements or successoral rights anterior to the Romanization. Current molecular biology techniques exploring mitochondrial DNA or Y chromosome have strengthened the scenario which considers the present Basques as the most direct descendants of a preneolithic Pyrenean people. During the last glacial maximum, the aquitanocantabric area would have served as a refuge for human groups who contributed thereafter to the repopulation of Western Europe. The genetic profile argues in favour of a strong degree of endogamy and drift. These two elements explain the presence of numerous cases of inherited disorders related to founding effects. The origin of the genetic heterogeneity is not yet established.

    The present 4-year longitudinal study examined physical growth and development of intermittent endurance run performance in young Basque soccer players aged 10-15 years applying multilevel regression modeling. Anthropometry, predicted adult stature and Yo-Yo Intermittent Recovery level 1 test (Yo-Yo IR1) of players from the under-11 teams from the Athletic Club of Bilbao were measured at pre- and end-season (two measurements per year of study, n = 33 considered for analysis). A non-linear effect of age on intermittent endurance run was observed, with significantly higher increases in Yo-Yo IR1 between 10-11 year-old and 14-15 year-old players. The development of Yo-Yo IR1 performance in all the years of the study was influenced positively by training exposure during the seasons (P 0.05). The steady development of intermittent endurance run performance during pubertal years in adolescent Basque soccer players is partially influenced by training exposure.

    Full Text Available The ceasefire of armed activities announced by ETA (Basque Homeland and Freedom in 2011 has fostered a debate about the violence and the victims of the terrorist organization. During those years, the violence perpetrated by ETA was characterized by bomb attacks and assassinations. In addition to this blatant violent behavior, a low-intensity violence was also taking place in the Basque Country, consisting of terrorist threats against their targets. There is, however, a lack of evidence-based research into this phenomenon. This investigation studies the impact of terrorist threats on the psychosocial functioning of people threatened by ETA in the Basque Country. Seventy-six people targeted by ETA completed self-reported survey. Terrorist threats and their derived psychosocial consequences were assessed by this way. The findings point out a relationship between terrorist threats and their psychosocial effects, which greatly affected the immediate environment of the targets too. The implications of these findings are discussed.

    2015-01-01

    Interannual variability of polychlorinated biphenyls (PCBs), measured in the soft tissues of Mytilus galloprovincialis mussels and Crassostrea gigas oysters, collected from estuarine waters within the Basque Country (Bay of Biscay), are investigated. Samples were collected in the autumn, between 2002 and 2011. Sites located within the ports of Bilbao and Pasaia showed the highest PCBs concentrations in molluscs; the lowest were observed in the mouth of the Oka estuary, an area of low population and industrial activity. Congener profiles of PCBs in the tissues of molluscs reveal the predominance of hexachlorobiphenyls (CB153 and CB138). In addition, redundancy analysis has shown that residence time, river flow and a 'pressure index' explain 57% of the variability in the PCB congener concentrations (the higher the values of these variables, the higher the concentration). Finally, Σ7PCB median concentrations in molluscs and sediments, collected from nearby sampling sites, were found to be moderately correlated (r(2)=0.513, p<0.01).

    Full Text Available This work gives us a picture of what and how long youngsters watch television according to a sample of 144 adolescents and young people from the Basque Country (Spain. The main aim is to know our reality and contrast it with available data from other researches. First of all, the results from other works on the television habits and preferences of youngsters are summarized and then the results obtained after applying the Questionnaire on Television Habits (QTH, which was set up “ad hoc” for this research, are presented. The obtained data show us that the time spent watching TV is not so long as we might have expected and this activity does not replace other ones either. As regards the television diet, the favourite contents are fiction series and news, but not the most harmful programmes.

    2007-07-01

    Full Text Available Human rights of immigrants have not been directly related to rights recognised to members of traditional minorities in some constitutional or international frameworks. However, immigration processes entail new demands of integrating linguistic rights within the public space and institutions. The Spanish example can open new challenges to multiculturalist approaches, since it brings together traditional and new linguistic diversity in a very significant level. In particular, new challenges arise in sub-state autonomous entities, as is the case in the Basque country, where linguistic diversity has been a traditional element of the society. These new multilingual realities challenge the traditional view of diversity and foce us to rethink the substantial contents of some fundamental rights in order to accommodate democratically linguistic diversity in post-modern societies.

    Sulphites are widely used as a preservative and antioxidant additive in food. The aim of this study was to assess dietary sulphite intake in adults aged 35-65 years and in children aged 4-18 years living in the Basque Country, northern Spain. We determined sulphite concentrations in 909 samples covering 16 food types. The maximum permitted levels were exceeded in 17% of samples. Making recommended assumptions for non-quantifiable results, estimates of mean lower and upper bounds were calculated for sulphite concentrations in each food type. These sulphite data were combined with consumption data derived from 8417 adults from the European Prospective Investigation in Cancer and Nutrition cohort in Gipuzkoa, recruited in 1992-1995 using a diet history method, and 1055 children from the Basque Country Nutrition Children Survey, conducted in 2004-2005 using two 24-h recall questionnaires to assess diet. The results were compared with the acceptable daily intake (ADI) proposed by the Joint Expert Committee on Food Additives (JECFA). The mean dietary exposure to sulphites was 0.08 mg kg⁻¹ bw day⁻¹, only 11% of the ADI in the overall group of children (4-18 years old), but the acceptable intake was exceeded by 4% of 4-6 year olds. For the adults (35-65 years old), the mean dietary exposure was 0.31 mg kg⁻¹ bw day⁻¹, 45% of the ADI, but the acceptable intake was exceeded in 14.6% of cases. The major contributing foods were minced meat and other meat products for children and wine for adults.

    An epidemiologic survey showed in 1992 iodine deficiency and endemic goiter in schoolchildren from the Basque Country. (1) To determine the percentage of homes of schoolchildren where iodized salt (IS) is used; (2) to assess iodine nutrition status in schoolchildren and to compare the data collected to those available from previous epidemiological studies. A cross-sectional study in 720 randomly selected schoolchildren. Urinary iodine concentration (UIC) was measured using high-performance liquid chromatography(HPLC) with electrochemical detection. IS was used at 53.0% of the homes (95% confidence interval [CI], 49.2-56.7%). Median UIC has increased by 226%, from 65 μg/L in 1992 to 147 μg/L (percentile [P], P(25), 99 μg/L; P(75), 233 μg/L) today. Both schoolchildren consuming IS and those using unfortified salt at their homes had UICs corresponding to adequate iodine intakes (165 and 132 μg/L respectively). UICs experienced great seasonal fluctuations, being 55% higher during the November-February period than in June-September period (191 μg/L vs 123 μg/L; p<0.001) Schoolchildren from the Basque Country have normalized their iodine nutrition status. The strong seasonal pattern of UICs suggests that consumption of milk and iodine-rich dairy products coming from cows feed iodized fodder is one of the most significant factors involved in the increase in iodine intake since 1992.

  15. HELIX: A Versatile SW Composition Instrument

    Sheldon, R.; Gallagher, D.; Adrian, M. L.

    2001-12-01

    Composition instruments have made themselves indispensable in the study of heliospheric plasmas, since only they are able to identify particle ``tracers" that reveal secrets of plasma origin and transport. However, future mission opportunities are likely to put severe constraints on present instrument designs, requiring a radical rethinking of mass spectrometry techniques. Time-of-flight methods currently give the highest mass resolution for the solar wind, but at the cost of limited dynamic range. Likewise magnetic deflection and quadrupole techniques have limitations that preclude their use for heliospheric studies. We present a novel SW mass spectrometer design that is capable of a breakthrough mass resolution M/Δ M>3000, in a 1 liter, 1 kg package with a huge geometric factor of 0.03cm2sr. Such capabilities enable new heliospheric science, such as the molecular identification of cometary or LISM constituents, the plasma composition of magnetic holes, or the triple isotopes of oxygen. Scaling this design down to more typical SW composition instrument abilities, we can achieve a mass resolution of M/Δ M=100 with a 5x10-4cm2sr in a 5 cm package weighing less than 100 grams. Such a miniature detector would be ideal for multiple space probes or a Pluto flyby. We will present the first preliminary data from a modulated ion beam demonstrating the mass resolution capabilities of this breakthrough design as well as some of the challenges in the implementation.

Quantitative pre- and post-intervention and qualitative evaluation, developed between 2012 and 2014. The Basque Country and Andalusia. A total of 409 patients and trainer-patients, participating in self-management peer training programmes. Intentional sample of 44 patients for the qualitative study. Bivariate analysis and net gains for common variables used in questionnaires in the Basque Country and Andalusia: self-reported health, daily activities, physical activity, use of health services, and self-management. Content analysis of 8 focus groups with patients and trainer-patients, including: coding, categorisation, and triangulation of results. Peer training has a positive impact on physical activity, the use of health services, and self-management, with some gender differences. The peer-training strategy is considered positive, as it strengthens the patient-health provider relationship, generates group support and self-confidence, and improves the emotional management. Patients identify two areas of potential improvement: access and continuity of training strategies, and more support and recognition from health providers and institutions. The positive impact on health and quality of life that this patient peer-training provides, requires the collaboration of health professionals and institutions, which should improve the access, continuity and adaptation to patient needs and expectations.

    2008-12-01

    The goal of this study is to establish the first archaeomagnetic record for the SW Pacific for the last few millennia using an outstanding collection of well-dated archaeological ceramics from a wide region, namely: 1. Bismarks-Northern Solomons 3500-0 BP, 2. Western Solomons 2000-0 BP, 3. Southeast Solomons 3100- 2000 BP, 4. Vanuatu 3100-700 BP, 5. New Caledonia 3000-0 BP, 5. Fiji -Tonga 3000-0 BP. Ultimately, we aim to investigate the potential for archaeomagnetic dating, especially of un-orientated inter-tidal samples that have proved impossible to date using C14 methods because of their disturbed contexts. Because the currently available samples are un-orientated, we are using palaeointensity measurements to establish the archaeomagnetic record. Although much archaeomagnetic intensity data (especially of the last three millennia) are already available, the geographic distribution of sites is very poor with a particular lack of data for the southern hemisphere. The new data will be the first such from the SW Pacific and should therefore contribute significantly to improving global field models. Preliminary measurements of palaeointensity from samples from the W-Solomon (site New Georgia, 3100 BP) and SE-Solomon (site Santa Cruz, 600 BP) Islands show a mean value of 33.4 ± 5.4 μT and 31.6 ± 4.2 μT, respectively. In addition we will present further results, primarily from Lakeba in Fiji (18.2° S, 178.8° E) and the Duke of York Islands in the Bismarck Archipelago (4.2° S, 152.5° E). Palaeointensity measurements are being carried out using the latest state of the art microwave demagnetisation methods in order to minimise alteration. We use pTRM and tail-checks in order to detect any thermo-chemical alteration and multi domain (MD) effects. Anisotropy and cooling rate are also determined and corrected for.

    Full Text Available The genus Lygodium Sw. is one of the few climbing ferns in the world. The spores of L. venustum Sw. and L. volubile Sw. were studied using light, scanning, and transmission electron microscopy. This work is based on herbarium material. The spores are trilete, triangular, with straight to convex sides in polar view. The equatorial diameter is 72-104 µm, and the polar diameter is 64-84 µm. The ornamentation in L. venustum is verrucate-tuberculate while in L. volubile, it is verrucate-tuberculate in the proximal face but with a few ridges on the distal face, where a micro-ornamentation constituted by verrrucae and tubercles is observed. An equatorial ridge is also present. The exospore is two-layered; in L. venustum, it is smooth in contrast with the ornamented exospore of L. volubile. The perispore of the two species analyzed is similar. This wall is four-layered with particular elements arranged radially in the middle layer. On the spores surface of both species, few spheroids are observed. The results introduced in the current study may be useful for the systematics of the genus as well as for phylogenetic purposes.O gênero Lygodium Sw. é um das poucas samambaias trepadoras no mundo.

The haplotype studies and multipoint linkage analysis suggest a localization of the MRX82 locus to an interval of 7.6 Mb defined by markers DXS6805 and DXS7346, in Xq24 and Xq25, respectively. No gene contained in this interval has been so far associated with nonsyndromic mental retardation, except for GRIA3, disrupted by a balanced translocation in a female patient with bipolar affective disorder and mental retardation. However, the search for mutations of this gene did not showed a pathogenic mutation in the present family. Given that there are other eight MRX families overlapping this interval, none of them with known mutation, we conclude that at least one new gene responsible for nonsyndromic mental retardation is located in this region.

    Fragile X-associated tremor/ataxia syndrome (FXTAS) and fragile X-associated primary ovarian insufficiency (FXPOI) are definitely related to the fragile X mental retardation 1 (FMR1) premutation (PM). Additional medical problems have also been associated with the PM, such as fibromyalgia, endocrine, and psychiatric disorders. To improve our understanding in the field, we reviewed all PM carriers and their reasons for any medical referrals from 104 fragile X families molecularly diagnosed in our laboratory and living in the Spanish Basque Country. After signing the written informed consent, we studied their electronic medical records in order to identify the disorders associated with the PM and their frequencies. We obtained clinical data in 188 PM carriers (147 women and 41 men). In women, the frequency of FXPOI (22.61%) was similar to that previously reported in PM carriers. In men, the frequency of definite FXTAS (28.57%) was lower than reported elsewhere. Furthermore, thyroid pathology was associated with the PM, the frequency of hypothyroidism being much higher in the studied region than in the general population (8.84% vs. 0.93%). Finally, we found no association with fibromyalgia or psychiatric problems. These findings represent another population contribution in this field and may be useful for the clinical management of PM carriers. PMID:27775646

  5. PRLs Promote Spreading, Adhesion, and Proliferation of Human SW480 and SW620 Cells

    Recent studies suggest that PRL-3 is involved in the metastasis of colorectal cancer, but the mechanism concerning that has not been well defined. This article expresses PRL-1, PRL-2, and PRL-3 and the catalytically inactive mutant forms of those enzymes in SW620 and SW480 cells, two human cell lines derived from non-metastatic cancer and metastatic colorectal cancer, respectively. While the expression of the native forms of PRLs promotes the spreading, adhesion, and proliferation of these cells, the expression of their mutant forms inhibits the earlier-mentioned processes. These data thus provide a cellular mechanism for the role of PRL-3 in tumor metastasis and suggest that all the three PRLs have similar functions.

    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.

    To describe the outcomes of the pilot program of a rapid HIV antibody screening test offered at Basque pharmacies, the socio-demographic characteristics of users and their acceptance of the test. Users of a rapid HIV antibody screening test (20 pharmacies) were surveyed. A random sample of 3514 tests (N = 806) performed in 1 year was taken. Statistical analyses included exact tests. There were 806 valid questionnaires. Seven tests were positive (0.85%; 95% confidence interval: 0.34-1.75); five of the users with positive tests were men. The mean age was 36.2 years (standard deviation = 11.0; range: 16-82 years; 70.7% men). Users' risk behavior was predominantly heterosexual and half of the users (58.6%) had no previous HIV tests. The main reasons for choosing this test were its speed, and the convenience and accessibility of community pharmacies. This new rapid HIV antibody screening test in community pharmacies could supplement other HIV screening programs currently in operation. Copyright © 2011 SESPAS. Published by Elsevier Espana.

    Full Text Available Abstract Background Since 2002, an active surveillance program for transmissible spongiform encephalopathy in small ruminants in European Union countries allowed identification of a considerable number of atypical cases with similarities to the previously identified atypical scrapie cases termed Nor98. Case presentation Here we report molecular and neuropathological features of eight atypical/Nor98 scrapie cases detected between 2002 and 2009. Significant features of the affected sheep included: their relatively high ages (mean age 7.9 years, range between 4.3 and 12.8, their breed (all Latxa and their PRNP genotypes (AFRQ/ALRQ, ALRR/ALRQ, AFRQ/AFRQ, AFRQ/AHQ, ALRQ/ALRH, ALRQ/ALRQ. All the sheep were confirmed as atypical scrapie by immunohistochemistry and immunoblotting. Two cases presented more PrP immunolabelling in cerebral cortex than in cerebellum. Conclusions This work indicates that atypical scrapie constitutes the most common small ruminant transmissible spongiform encephalopathy form in Latxa sheep in the Spanish Basque Country. Moreover, a new genotype (ALRQ/ALRH was found associated to atypical scrapie.

    Alzheimer's disease (AD) is the most common dementing disorder and presents with a progressive and irreversible cognitive decline of gradual onset. To date, several reports have involved iron in AD physiopathology. In this study, we have analysed TFC2 variant and HFE mutations (H63D and C282Y) in 211 AD patients and 167 controls recruited from an area of the Basque Country. Furthermore, we have studied APOE genotype as it is a well-known risk factor for AD. APOE epsilon 4 allele was associated with an increased risk of AD and an earlier age at onset, whereas no association was found between TFC2 or HFE C282Y mutation and disease susceptibility. The frequency of H63D mutation was higher in control population (29.9%) than in AD patients (18%), suggesting a protective role of this allele on AD either due to the presence of the mutation itself or through the effect of other related genes in the ancestral haplotype in which it is included.

  11. SW radiative effect of aerosol in GRAPES_GFS

    The aerosol particles can scatter and absorb solar radiation, and so change the shortwave radiation absorbed by the atmosphere, reached the surface and that reflected back to outer space at TOA. Since this process doesn't interact with other processes, it is called direct radiation effect. The clear sky downward SW and net SW fluxes at the surface in GRAPES_GFS of China Meteorological Administration are overestimated in Northern multitudes and Tropics. The main source of these errors is the absence of aerosol SW effect in GRAPES_GFS. The climatic aerosol mass concentration data, which include 13 kinds of aerosol and their 14 SW bands optical properties are considered in GRAPES_GFS. The calculated total optical depth, single scatter albedo and asymmetry factor are used as the input to radiation scheme. Compared with the satellite observation from MISER, the calculated total optical depth is in good consistent. The seasonal experiments show that, the summer averaged clear sky radiation fluxes at the surface are improved after including the SW effect of aerosol. The biases in the clear sky downward SW and net SW fluxes at the surface in Northern multitudes and Tropic reduced obviously. Furthermore, the weather forecast experiments also show that the skill scores in Northern hemisphere and East Asia also become better.

    As result of long-term scientific activities in the southwest Indian Ocean, an extensive amount of swath bathymetric data has accumulated in the AWI database. Using this data as a backbone, supplemented by additional bathymetric data sets and predicted bathymetry, we generate a comprehensive regional bathymetric data compilation for the southwest Indian Ocean. A high resolution bathymetric chart of this region will support geological and climate research: Identification of current-induced seabed structures will help modelling oceanic currents and, thus, provide proxy information about the paleo-climate. Analysis of the sediment distribution will contribute to reconstruct the erosional history of Eastern Africa. The aim of swIOBC is to produce a homogeneous and seamless bathymetric grid with an associated meta-database and a corresponding map for the area from 5° to 39° S and 20° to 44° E. Recently, multibeam data with a track length of approximately 86,000 km are held in-house. In combination with external echosounding data this allows for the generation of a regional grid, significantly improving the existing, mostly satellite altimetry derived, bathymetric models. The collected data sets are heterogeneous in terms of age, acquisition system, background data, resolution, accuracy, and documentation. As a consequence, the production of a bathymetric grid requires special techniques and algorithms, which were already developed for the IBCAO (Jakobsson et al., 2012) and further refined for the IBCSO (Arndt et al., 2013). The new regional southwest Indian Ocean chart will be created based on these methods. Arndt, J.E., et al., 2013.

    Yersiniosis is a zoonosis widely distributed in Europe and swine carry different serotypes of Yersinia enterocolitica and Y. pseudotuberculosis. The aim of this study was to determine the prevalence of Y. enterocolitica and Y. pseudotuberculosis in wild boars in northern Spain. The blood of wild boars (n = 505) was sampled between 2001 and 2012. Seroprevalence was determined in 490 serum samples with an indirect enzyme-linked immunosorbent assay. Seventy-two of the animals were also examined for the presence of Y. enterocolitica or Y. pseudotuberculosis in the tonsils with real-time polymerase chain reaction. All the tonsils were analysed twice, directly and after cold enrichment in phosphate-buffered saline supplemented with 1 % mannitol and 0.15 % bile salts. Antibodies directed against Y. enterocolitica and Y. pseudotuberculosis were detected in 52.5 % of the animals. Yersinia enterocolitica was detected with real-time polymerase chain reaction in 33.3 % of the wild boars and Y. pseudotuberculosis in 25 %. Significant differences were observed according to the sampling year, and the highest prevalence was during winter and spring. The highest antibody levels and Y. enterocolitica prevalence were observed in mountainous areas at altitudes higher than 600 m, with very cold winters, and with the highest annual rainfall for each dominant climate. Areas with low and medium livestock populations were associated with the highest seroprevalence of Yersinia spp. in wild boars, whereas areas with high ovine populations had the highest prevalence of Y. enterocolitica. This study shows that Y. enterocolitica and Y. pseudotuberculosis are highly prevalent among wild boars in the Basque country, with Y. enterocolitica most prevalent. The risk of infection among wild boars is influenced by the season and the area in which they live.

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

    2003-01-01

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

    The pollen grains of Quercus spp. (oak trees) are allergenic. This study investigates airborne Quercus pollen in SW Spain with the aim identifying favourable conditions for atmospheric transport and potential sources areas. Two types of Quercus distribution maps were produced. Airborne Quercus pollen concentrations were measured at three sites located in the Extremadura region (SW Spain) for 3 consecutive years. The seasonal occurrence of Quercus pollen in the air was investigated, as well as days with pollen concentrations ≥80Pm(-3). The distance that Quercus pollen can be transported in appreciable numbers was calculated using clusters of back trajectories representing the air mass movement above the source areas (oak woodlands), and by using a state-of-the-art dispersion model. The two main potential sources of Quercus airborne pollen captured in SW Spain are Q. ilex subsp. ballota and Q. suber. The minimum distances between aerobiological stations and Quercus woodlands have been estimated as: 40km (Plasencia), 66km (Don Benito), 62km (Zafra) from the context of this study. Daily mean Quercus pollen concentration can exceed 1,700Pm(-3), levels reached not less than 24 days in a single year. High Quercus pollen concentration were mostly associated with moderate wind speed events (6-10ms(-1)), whereas that a high wind speed (16-20ms(-1)) seems to be associated with low concentrations.

    The High Atlas is a 100 km wide zone defined by E-W to NE-SW trending folds nearly orthogonal to the Atlantic coastline. The major compressional structures in the High Atlas consist of large-scale fold systems which affect Mesozoic and Cainozoic formations. The extreme West of the High Atlas including the region of Agadir is defined as an earthquake Zone. Historical seismicity data shows that the Agadir region was hit by two destructive earthquakes in 1731 and 1960 with magnitude 6.4 and 6.0, respectively. The present study has two main goals: 1) to use remote sensing techniques to detect and map the surface geological structures including faults; 2) to use the local earthquake tomography for imaging the lithosphere (subsurface) and detect deep structures. For the remote sensing techniques we used ETM + Landsat7 images and the SRTM 90 m image as a Digital Terrane Elevation Model. This study focuses on the computerized identification, feature extraction and quantitative interpretation of lineaments over the SW High Atlas. The analysis developed here is based on the numerical enhancement of a Landsat image and on the statistical processing of data generated through enhancement. The results generated by the numerical enhancement and statistical analysis are presented on fault maps, lineament maps, polar diagrams and lineament density maps. The lineaments have a high concentration of orientations around the directions N40E, N80W and N-S. For the subsurface study, seismic data sets were used to define the 3-D velocity structures. We also used local earthquake tomography to obtain the velocity map and crustal structure of the SW High Atlas region. The tomography results show a new and detailed lithosphere structure defined by a high velocity body in the northern of SW High Atlas from 15 to 45 Km depth, dipping to the north beneath the Essaouira basin in the western Meseta with P velocity variations from 6.5 to 7.8 km/s. This anomaly can be interpreted as an old

    Pitch canker, caused by Fusarium circinatum, is a destructive disease of Pinus species and has recently been shown to represent a substantial threat to natural and commercial forests in northern Spain. The genetic diversity of F. circinatum in the Basque Country of Spain was assessed by characterising 96 isolates based on vegetative compatibility groups (VCGs), mating type assays, polymorphic DNA-markers and amplified fragment length polymorphism (AFLP) analyses. For this purpose, F. circinatum isolates were collected from diseased Pinus radiata as well as from insects associated with this host. Overall, a low level of diversity was detected in the population. The isolates represented only two VCGs and they were all of the same mating type. AFLP analyses revealed three genotypes and polymorphic DNA-markers specific for F. circinatum showed nine genotypes. The most common genotypes represented 97% of all isolates for AFLP analysis and 68% of isolates for the polymorphic DNA-marker sets. Over all, this indicates that pitch canker in the Basque Country of Spain is caused by a clonally propagating population of F. circinatum, typical of a recently introduced pathogen.

  18. Were They Tortured or Did They Make that Up? Ethnographic Reflections on Torture Allegations in the Basque Country in Spain

    Directory of Open Access Journals (Sweden)

    2011-02-01

    Full Text Available Academic literature about torture has addressed a wide range of questions. An important facet, however, has not yet received sufficient attention. Given that torture tends to occur in secrecy, how does the lack of information that is perceived to be objective and authoritative affect the societal response to allegations of torture and the social consequences of such allegations?  In this article, the controversy about torture allegations in Spain is used to examine this issue and explore the insidious effects the uncertainty has on society.  The Spanish state is unable to provide a generally accepted account in response to the continuous torture allegations from Basque prisoners accused of terrorism or street violence.   Based on ethnographic research, this article describes how Spanish and Basque society can be divided in believers, non-believers and people who do not care about torture allegations.  Because of the centrality of such allegations in many criminal cases, this division also polarizes public perceptions of the entire criminal justice system.  DOWNLOAD THIS PAPER FROM SSRN: http://ssrn.com/abstract=1838392

  3. Spanish stop-rhotic sequences in Spanish-Basque bilinguals and second language learners: An acoustic study

    Science.gov (United States)

    Weissglass, Christine A.

    This dissertation investigates transfer and markedness in bilingual and L2 Spanish stop-rhotic sequences (e.g., the 'br' in brisa 'breeze'). It also examines the phonetics-phonology interface in Spanish. To this end, it explores the production of these sequences in two different experiments. Experiment 1 compares the production of these sequences by 6 Spanish monolinguals and 6 Spanish-Basque bilinguals. Experiment 2 does so for 25 L2 learners and 5 native Spanish speakers. Acoustic analysis of these sequences revealed that Spanish-Basque bilinguals produced trills 5% of the time whereas Spanish monolinguals did not have any trills. Additionally, fricative rhotics and coarticulation accounted for 35% of L2 realizations, but were not present in the native Spanish speaker dataset. These findings indicate a role for transfer in both bilingual and L2 phonological acquisition, although it is more prevalent in the L2 learner dataset. This is in line with the Speech Learning Model (Flege, 1995), which posits a stronger role for transfer amongst late learners (i.e., L2 learners) than early learners (i.e., Spanish-Basque bilinguals). In order to examine the role of markedness in bilingual and L2 phonological acquisition, this dissertation investigates the role of sonority in bilingual and L2 Spanish syllable structure. To do so, it proposes a sonority hierarchy for rhotic variants based on their specifications for voicing, intensity and continuancy. According to this hierarchy, approximant rhotics are the most sonorous, followed by taps, trills and fricative rhotics. Therefore, approximant rhotics were expected to be the most common realization followed by taps, trills and fricative rhotics. Although Spanish monolinguals adhered to this expectation, the other groups did not; taps were the most common realization for Spanish-Basque bilinguals, L2 learners, and native Spanish speakers and fricative rhotics were more common than trills for Spanish-Basque bilinguals and L2

    Our recent reinterpretation for seismic refraction/wide-angle reflection data in eastern Kii Peninsula, SW Japan, provided new structural information on the uppermost part of the subducted Philippine Sea (PHS) plate and overriding the SW Japan arc, including the landward reflectivity variation in the vicinity of the plate boundary and the large scale structural change within the SW Japan arc. The Kii peninsula is located in the eastern part of the well-known subduction zone along the Nankai trough where offshore M8-class megathrust earthquakes repeatedly occur. The plate boundary beneath this Peninsula is in the stable or conditionally stable regime except for its southernmost tip, which corresponds to the northwestern end of the rupture area at the last event (1944 Tonankai earthquake (M7.9)). The surface geology of the overriding SW Japan arc is divided to two parts by the E-W trending Median Tectonic Line (MTL), the most prominent tectonic boundary in SW Japan. South of the MTL, Cretaceous-Jurassic accretionary complexes are exposed, whose northernmost unit consists of high P-T metamorphic rocks (the Sanbagawa metamorphic belt (SMB)). The region north of the MTL is occupied by older accretionary complexes, partly suffered from the Cretaceous magmatic intrusions. Our seismic data from five dynamite shots were acquired in 2006 along 80-km line almost perpendicular to the Nankai trough. The structure of the SW Japan arc was obtained both from intensive wide-angle reflection analysis and advanced reflection processing by seismic interferometry technique. The former analysis delineated clear structural change in the uppermost crust across the MTL. In the latter processing, we retrieved virtual shot records at 512 receiver points from free-surface backscattered waves by the deconvolution interferometry. The subsequent CRS (Common Reflection Surface)/MDRS (Multi-Dip Reflection Surfaces) methods provided an enhanced image within the island arc, including a northward

    A total of forty-three galena samples from syngenetic and epigenetic Pb-Zn mineralizations emplaced in the Lower Cretaceous Basque-Cantabrian basin and Paleozoic basement of the Cinco Villas massif in the western Pyrenees, have been analyzed for Pb-isotopic composition. Galena from sedex mineralizations hosted in Carboniferous clastic rocks in the Cinco Villas massif display an homogeneous lead isotopic signature (206Pb/2044Pb ≈ 18.43, 207Pb/204Pb ≈ 15.66, 208Pb/ 204Pb ≈ 38.69) suggesting a single lead reservoir. These values are slightly more radiogenic than lead from other European Hercynian deposits, possibly reflecting the influence of a more evolved upper crustal source. Underlying Paleozoic sediments are proposed as lead source for the Cinco Villas massif ores. Analyses from twenty-six galena samples from the four strata-bound ore districts hosted in Mesozoic rocks reveal the existence of two populations regarding their lead isotopic composition. Galena from the western Santander districts (e.g., Reocin) is characterized by more radiogenic isotope values (206Pb/204Pb ≈ 18.74, 207Pb/204Pb ≈ 15.67, 208Pb/ 204Pb ≈ 38.73) than those from the central and eastern districts (Troya-Legorreta, Central and Western Vizcaya, 206Pb/204Pb ≈ 18.59, 207Pb/204Pb ≈ 15.66, 208Pb/ 204Pb ≈ 38.73). In all districts, the most likely source for these mineralizations was the thick sequence of Lower Cretaceous clastic sediments. The existence of two separate lead isotopic populations could be the result of regional difference in the composition of the basement rocks and the clastic sediments derived of it or different evolution histories. In both sub-basins, isotopic ratios indicate an increase in crustal influence as the age of the ores decreases.

    We have undertaken a comprehensive, integrated, cyclo-magneto stratigraphic analysis and study of the calcareous nanno fossils of the Upper Maastrichtian hemi pelagic succession in three sections of the Basque Basin (Zumaia, Sopelana and Hendaia). The sections were correlated at bed-by-bed scale through careful analysis of the lithological stacking pattern and significant sedimentary features. For spectral analysis we used an available high-resolution carbonate proxy record spanning 64 m of section below the K/Pg (Cretaceous/ Palaeogene) boundary at Zumaia containing 72 precession-related limestone-marl couplets. The continuous wavelet spectrum helped to determine and visualize the orbital forcing at both the short ({approx}100-ky) and long (405-ky) eccentricity band. We applied bandpass Gaussian filters to the carbonate record to extract the relevant periodicities and provide a cycle-numbering scheme starting at the K/Pg boundary. The full hierarchy of precession cycles and eccentricity-related bundles is then extended toward the base of the section in question, which contains a total of 33 short eccentricity-related bundles, thus spanning more than 3 Ma. The chron C31r/ C31n boundary (estimated to occur at {approx}3.08 Ma below the K/Pg boundary) in the lower part of the succession was determined unambiguously in all three sections studied although the C30n/C29r reversal could not be determined due to a pervasive reverse magnetization acting on the purplish lithologies in the upper part of the succession. Relevant calcareous plankton bio events could be accurately placed on the cyclo-magneto stratigraphic template. The cyclo stratigraphic framework also allowed us to estimate the duration of previously defined sea-level-related 3rd-order depositional sequences in the basin, which appear to be strongly paced by the long-term 1.2 My obliquity amplitude modulating cycle. This is an outstanding feature in the Maastrichtian greenhouse period, during which continental

    Many ethnobotanical studies show that people in industrial countries still rely on their traditional knowledge of medicinal plants for self-treatment, although the trend might not be as common as some decades ago. Given the social and public health implications of ethnopharmacological practices, this survey aims at recording and analysing the medicinal plants used in the folk medicine of the Northwest of the Basque Country focusing on how medicinal plants knowledge and practices evolve. Fieldwork consisted of 265 orally consented semi-structured interviews with 207 informants about medicinal uses of plants. Interviews were conducted between September 2008 and January 2011. Informants were on average 76 years old (minimum 45, maximum 95), being more than half of them (112) men. Data collected were structured in use-reports (UR). Following informants' comments, medicinal use-reports were classified as abandoned-UR, when the informants reported that the use was only practiced in the past, and prevalent-UR, when the informants reported to continue the practice. A total of 2067 UR for 139 species that belong to 58 botanical families were recorded, being the most important families Asteraceae, Liliaceae sensu latu and Urticaceae. Some of the most important species are commonly used in other European areas (e.g., Chamaemelum nobile, Urtica dioica and Chelidonium majus). However, there are also plants commonly used in the area such as Helleborus viridis or Coronopus didymus, that are scarcely used in other areas, and whose record is an original contribution of the local pharmacopeia. It is also the case of remedies such as the use of Plantago leaves against strains in a local remedy called zantiritu. Overall, and for all variables analysed (total UR, medicinal use-categories, drug preparation and administration), the percentage of UR being currently practiced (prevalence ratio) was very low (near 30%) suggesting a strong decay in the use of traditional medicinal plants

    Full Text Available The exploration direction and targets for the large-scale Middle Permian gas reservoirs in the Sichuan Basin are hot spots and challenges in current exploration researches. The exploration successes of large gas field of Cambrian Longwangmiao Formation in Gaoshiti-Moxi region, Central Sichuan Basin, indicated that prospective sedimentary facies belt was the basis for the formation of large gas fields. In this paper, based on seismic data, outcrop data and drilling data, the tectonic framework and sedimentary features of the Middle Permian in the SW Sichuan Basin were comprehensively studied. The following conclusions were reached from the perspective of sedimentary facies control: (1 during the Middle Permian, this region was in shallow water gentle slope belts with high energy, where thick reef flat facies were deposited; (2 the basement was uplifted during Middle Permian, resulting in the unconformity weathering crust at the top of Maokou Formation due to erosion; the SW Sichuan Basin was located in the karst slope belt, where epigenic karstification was intense; and (3 reef flat deposits superimposed by karst weathering crust was favorable for the formation of large-scale reef flat karst reservoirs. Based on the combination of the resources conditions and hydrocarbon accumulation conditions in this region, it was pointed out that the Middle Permian has great potential of large-scale reef flat karst gas reservoir due to its advantageous geological conditions; the Middle Permian traps with good hydrocarbon accumulation conditions were developed in the Longmen Mountain front closed structural belt in the SW Sichuan Basin and Western Sichuan Basin depression slope belt, which are favorable targets for large-scale reef flat karst reservoirs.

    We have estimated the Curie Point Depth (CPD) using the average radial power spectrum in a tectonically complex area located in the SW Caribbean basin. Data analyzed came from the World Digital Magnetic Anomaly Map, and three methods have been used to compare results and evaluate uncertainties: Centroid, Spectral Peak, and Forward Modeling. Results show a match along the three methods, suggesting that the CPD values in the area ranging between 6 km and 50 km. The results share the following characteristics: A) High values (> 30 km) are in continental regions; B) There is a trend of maximum CPD values along the SW-NE direction, starting from the Central Cordillera in Colombia to the Maracaibo Lake in Venezuela; C) There is a maximum CPD at the Sierra Nevada de Santa Marta (Colombia) as well as between Costa Rica - Nicaragua and Nicaragua - Honduras borders. The lowest CPD values (coastal regions and offshore. We also tested results by estimating the geothermal gradient and comparing measured observations of the study area. Our results suggest at least five thermal terrains in the SW Caribbean Basin: A) The area that is comprising the Venezuela Basin, the Beata Ridge and the Colombia Basin up to longitude parallel to the Providencia Throat. B) The area that includes zones to the north of the Cocos Ridge and Panam Basin up to the trench. C) The orogenic region of the northern Andes and including areas of the Santa Marta Massif. D) The continental sector that encompasses Nicaragua, northern Costa Rica and eastern of Honduras. E) Corresponds to areas of the northern Venezuela and Colombia, NW of Colombia, the Panamanian territory and the transition zones between the Upper and Lower Nicaragua Rise.

    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.

    Preliminary results on the magnetostratigraphy of three Neogene formations from SW Uruguay are presented: Camacho, Raigón and Libertad, and a relative age from the record of reversions in the Earth's magnetic field polarity is proposed. The sediments outcrop in the SW region of Uruguay,and have been received attention due to their fossil contents. The oldest is the late Miocene-Pliocene Camacho Fm, of Huayquerian to Montehermosan affinities. A Pliocene-early Pleistocene age has been assigned to Raigón Fm, of Chapadmalalan affinities. The overlying Libertad Fm has been considered early-middle Pleistocene in age, and to have Marplatan-Ensenadan affinities. The lithology of this facies of Camacho Fm is identified by the presence of fine to very fine sandstones and is composed of silty-sandy and bioturbed silty deposits. The marine facies of this formation is rich in fossil content, as several invertebrate and vertebrate taxa are found. The upper Raigón Fm is formed by sandstones of varied grain size and includes lenses and levels of claystones and conglomerates. It shows the sedimentological features of a deep, pebble-rich braided fluvial system. The 383 vertebrate specimens found in the sandy facies and studied in a taphonomically-oriented study belong to 19 genera and 13 higher taxa. The bones are disarticulated, with smooth fractures and little weathered or abraded, which is congruent with a short time of contact, as observed in strong and sudden flows. The elements belong to the three Voorhies groups and fractured specimens are found along with well preserved materials, implying different taphonomical histories and reworking. The consequent inferred time averaging urges caution at using these remains for defining precise ages. The Libertad Fm, top of the sequence, is conformed by greenish clays, clayey fine sandstones, medium sized sandstones and conglomeratic levels, corresponding to deposits of continental origin under a semiarid climate, which allowed the

    In March 2015, an atypical G3P[8] rotavirus with an equine-like VP7 gene was detected in Gipuzkoa (Basque Country, Spain) and spread contributing significantly to the seasonal epidemic. The strain was identified in fecal samples collected from 68 patients, mainly children from rural and urban settings with acute gastroenteritis, representing 14.9% of the 455 rotavirus strains genotyped between July 2014 and June 2015. Seven patients (10.3%) were hospitalized. Full genome analysis of six of these strains revealed a DS-1-like genotype constellation, G3-P[8]-I2-R2-C2-M2-A2-N2-T2-E2-H2, and showed that most genome segments shared the highest nucleotide sequence identity with strains isolated in Japan, Thailand, Australia and the Philippines. The strains of Gipuzkoa were similar to novel G3P[8] reassortant rotaviruses with an equine-like VP7 gene and a DS-1-like genetic backbone that emerged in the Asia-Pacific Region in 2013. The study highlights the circulation of these atypical rotaviruses outside the Asia-Pacific Region of origin, and their emergence in a European Region. Due to their unusual genotype constellation, these strains pose a challenge for the rotavirus strain surveillance, since G-/P-typing, the most commonly used classification system, cannot identify this type of intergenogroup reassortants.

    Group phenomena have been used since antiquity in therapeutic, social, economic and political domains. According to Bion, the interactions between group members generate a ``group unconscious'' and its behavior is governed and oriented by Bion's ``basic assumptions.'' The present work has been conducted during group analysis training at the Basque Foundation for the Investigation of Mental Health (OMIE) at Bilbao, consisting of eleven sessions. The participants are presented with an ``absurd questionnaire'' proposing 50 pairs of images, in each of which one image has to be chosen. The results are used to search for evidence in favor of the influence of group dynamics on individual choices of the images proposed in the questionnaire. Our analysis finds some evidence for an effect of group dynamics both on the initial choice of the pictures and on the evolution of the number of changes (swaps) of picture choices across the eleven sessions. We interpret these effects in the light of Bion's view of group dynamics...

    A virtual professional community of practice (VCoP), HOBE+, has been set up to foster and facilitate innovation in primary care. It is aimed at all primary care professionals of the Basque Public Health Service (Osakidetza) in the provinces of Biscay and Araba. HOBE + is a VCoP that incorporates innovation management from the generation of ideas to their implementation in primary care practice. We used a case study method, based on the data provided by the technology platform that supports the VCoP, and from a survey completed by HOBE + users. The target population was all primary care staff (including all professional categories) from Araba and Biscay provinces of the Basque Country (Spain), who represent the target users of the VCoP. From a total of 5190 professionals across all the professional categories invited to join, 1627 (31.3%) actually registered in the VCoP and, during the study period, 90 (5.5% of the registered users) participated actively in some way. The total number of ideas proposed by the registered users was 133. Of these, 23 ideas (17.2%) are being implemented. Finally, 80% of the users who answered the satisfaction survey about their experience with HOBE + considered the initiative useful in order to achieve continuous improvement and real innovation in clinical and managerial processes. The experience shows that it is possible to create a virtual CoP for innovation in primary care where professionals from different professional categories propose ideas for innovation that are ultimately implemented.This manuscript objectives are to assess the process of developing and implementing a VCoP open to all primary care professionals in Osakidetza, including the take-up, participation and use of this VCoP in the first 15 months after its launch in October 2011. In addition, the usefulness of the VCoP was assessed through a survey gathering the opinions of the professionals involved.

One of the sources is associated with the remarkable periodic time-variable infrared source LRLL 54361, opening the possibility of monitoring this object at radio wavelengths. Four of the sources appear to be powering outflows in the region, including HH 211 and HH 797. In the case of the rotating outflow HH 797 we detect at its center a double radio source, separated by $\\sim3"$. Two of the sources are associated with infrared stars that possibly have gyrosynchrotron emission produced in active magnetospheres. Finally, three of the sources are interpreted as background objects.

    We mapped a 13 by 22 pc region in emission from 492 GHz [C I] and, for the first time, 551 GHz ^{13}CO(5-4) in the giant molecular cloud M17SW, using the Submillimeter Wave Astronomy Satellite. The morphologies of the [C I] and ^{13}CO emission are strikingly similar. The extent and intensity of the [C I] and ^{13}CO(5-4) emission is explained as arising from photodissociation regions on the surfaces of embedded molecular clumps. Modeling of the ^{13}CO(5-4) emission in comparison to ^{13}CO(1-0) indicates a temperature gradient across the cloud, peaking to at least 63 K near the M17 ionization front and decreasing to at least 20 K at the western edge of the cloud. We see no correlation between gas density and column density. The beam-averaged column density of C I in the core is 1x10^{18} cm^-2, and the mean column density ratio N(C I)/N(CO) is about 0.4. The variations of N(C I)/N(CO) with position in M17SW indicate a similar clump size distribution throughout the cloud.

    The deep sub-seafloor biosphere is among the least-understood habitats on Earth, even though the huge microbial biomass plays a potentially important role in long-term controls of global biogeochemical cycles. The research team from Taiwan, supported by the Central Geological Survey (CGS), has been demonstrated at SW offshore Taiwan that indicated this area is potential gas hydrate region. Therefore, the Gas Hydrate Master Program (GHMP) was brought in the National Energy Program-Phase II (NEP-II) to continue research and development. In this study, the microbial community structure of potential gas hydrate bearing sediments of giant piston core MD-178-10-3291 (KP12N) from the Kaoping Canyon offshore SW of Taiwan were investigated. This core was found many empty spaces and filling huge methane gas (>99.9 %) that might dissociate from solid gas hydrate. 16S rRNA gene clone libraries and phylogenetic analysis showed that the dominant members of Archaea were ANME (13 %), SAGMEG (31 %) and DSAG (20 %), and those of Bacteria were Chloroflexi (13 %), Candidate division JS1 (40 %) and Planctomycetes (15 %). Among them, ANME-3 is only distributed at the sulfate-methane interface (SMI) of 750 cmbsf, and sharing similarity with the Hydrate Ridge clone HydBeg92. ANME-1 and SAGMEG distributed below 750 cmbsf. In addition, DSAG and Candidate division JS1 are most dominant and distributed vertically at all tested depths from 150-3600 cmbsf. Combine the geochemical data and microbial phylotype distribution suggests the potential of gas hydrate bearing sediments at core MD-178-10-3291 (KP12N) from the Kaoping Canyon offshore SW of Taiwan.

    Introduction: Type 2 diabetes mellitus (DM2) is a disease with high prevalence and significant impact in terms of mortality and morbidity. The increased prevalence of the disease requires the implementation of new strategies to promote patient self-management. The Spanish Diabetes Self-Management Program (SDSMP) proved to be effective in other settings. The objective of this study is to assess its effectiveness in terms of care for DM2 patients in primary care settings within the Basque Healt...

    Riverine carbon fluxes of some catchments in the world have significantly changed due to contemporary climate change and human activities. As a large region with an extensive karstic area of nearly 7.5 × 105 km2, Southwest (SW) China has experienced dramatic climate changes during recent decades. Although some studies have investigated the karst-related carbon sink in some parts of this region, the importance of climate impacts have not been assessed. This research examined the impacts of recent climate change on the karst-related carbon sink in the SW China for the period 1970-2013, using a modified maximal potential dissolution (MPD) method and GIS. We first analyzed the major determinants of carbonate dissolution at a spatial scale, calculated the total karst-related carbon sink (TCS) and carbon sink fluxes (CSFs) in the SW China karst region with different types of carbonate rocks, and then compared with other methods, and analyzed the causes of CSFs variations under the changed climate conditions. The results show that the TCS in SW China experienced a dramatic change with regional climate, and there was a trend with TCS decreasing by about 19% from 1970s to 2010s. This decrease occurred mostly in Guizhou and Yunnan provinces, which experienced larger decreases in runoff depth in the past 40 years (190 mm and 90 mm, respectively) due to increased air temperature (0.33 °C and 1.04 °C, respectively) and decreased precipitation (156 mm and 106 mm, respectively). The mean value of CSFs in SW China, calculated by the modified MPD method, was approximately 9.36 t C km- 2 a- 1. In addition, there were large differences in CSFs among the provinces, attributed to differences in regional climate and to carbonate lithologies. These spatiotemporal changes depended mainly on hydrological variations (i.e., discharge or runoff depth). This work, thus, suggests that the karst-related carbon sink could respond to future climate change quickly, and needs to be considered in

    Full Text Available This petrographic study of rock samples from the area of a large-scale shear zone, the Sottung-Jurmo shear zone, in SW Finland, illuminates the thermal development of and strain distribution within the rocks during the last development stages of the shear zone. The results indicate relatively high temperatures during the deformation phases that created the gneisses and the mylonites, strain partitioning through time and continued transpression from S-SW until at least c. 1.79 Ga. This has implications to the latest tectonic models since the results together with previous studies suggest acompartmentalisation of regional stresses between the area SW of the shear zone and central Fennoscandia. The results also suggest that the uplift rate increased during the late stage of the transpression.

    The history of the Late Cenozoic stress regime was determined for an area between the gulfs of Fethiye and Antalya. Fault kinematic analysis and inversion of focal mechanisms of shallow earthquakes reveal significant evolution of the regional stress regime in SW Anatolia, i.e., the area of interaction between the Hellenic and Cyprus arcs, from the Mio-Pliocene to the present time. Fault kinematic analysis yields two different normal faulting stress regimes along the southwestern part of Fethiye-Burdur Fault zone, e.g., in and around Çameli Basin (Zone A1) and two different strike-slip to normal faulting stress regimes characterized by a roughly orthogonal set of extensional axes between Fethiye and Demre (Zone B) with an older NW-SE σ3 axis for Mio-Pliocene and a younger NE-SW σ3 axis for Plio-Quaternary time. Inversion of focal mechanisms of the earthquakes occurring in Zone A1 provides an extensional stress state with approximately N-S σ3 axis. Inversion of those occurring in Zone B, south of Zone A1, yields a dominantly strike-slip stress state with a NE-SW σ3 axis and a NW-SE σ1 axis respectively. The inversion slip vectors from fault planes yield a consistent normal faulting stress regime in Burdur Basin and its surroundings (i.e., along the northeastern part of Fethiye-Burdur Fault Zone, (Zone A2)) during Plio-Quaternary, continuing into recent time as indicated by earthquake focal mechanism inversions. Both states have a consistent NW-SE σ3 axis. Fault kinematic analysis indicates NW-SE extension acting in Zone C (subarea between Demre and Antalya), south of Zone A2, during Mio-Pliocene time. The inversion of focal mechanisms yields normal faulting also characterized by a consistent NW-SE σ3 axis. The nearly orthogonal extensional stress regimes (NW-SE and NE-SW) obtained by inversion of both measured and seismic faults seem to have been acting contemporaneously with each other at different intensities from the Mio-Pliocene onwards in SW Turkey.

    SW Norway has experienced a complex brittle history after cessation of the Caledonian orogeny, and the recent discoveries of major hydrocarbon reserves in heavily fractured and weathered basement offshore SW Norway has triggered a renewed interest in understanding this complex tectonic evolution. In this contribution we present results from a multidisciplinary study combining lineament analysis, field work, paleo-stress inversion, mineralogical characterization and radiometric dating in the Bømlo area of SW Norway in order to develop a tectonic model for the brittle evolution of this important region. The study area mainly consists of the Rolvsnes granodiorite (U-Pb zircon age of ca. 466 Ma), which is devoid of penetrative ductile deformation features. The first identified brittle faults are muscovite-bearing top-to-the-NNW thrusts and E-W striking dextral strike-slip faults decorated with stretched biotite. These are mechanically compatible and are assigned to the same NNW-SSE transpressional regime. Ar-Ar muscovite and biotite dates of ca. 450 Ma (Late Ordovician) indicate fault activity in the course of a Taconian-equivalent orogenic event. During the subsequent Silurian Laurentia-Baltica collision variably oriented, lower-grade chlorite and epidote-coated faults formed in response to a ENE-WSW compressional stress regime. A large number of mainly N-S striking normal faults consist of variably thick fault gouge cores with illite, quartz, kaolinite, calcite and epidote mineralizations, accommodating mainly E-W extension. K-Ar dating of illites separated from representative fault gouges and zones of altered granodiorite constrain deformation ranging from the Permian to the Late Jurassic, indicating a long history of crustal extension where faults were repeatedly activated. In addition, a set of ca. SW-NE striking faults associated with alteration zones give Cretaceous dates, either representing a young phase of NW-SE extension or reactivation of previously formed

This paper describes the requirements of Stylosanthes guianensis in two ecological regions : Mosso (1 280 m alt. and lower Ruzizi (800 m alt.. This legume was introduced in 1953 into the grasslands of the east and in 1970 into lower Ruzizi, with the aim of improving the value of the natural pastures using leguminous plants. At Mosso, soil and climatic conditions were favourable for Stylosanthes and it grew well. However, since 1981. Anthracnose has severely reduced its growth and until a solution is found its general introduction will not be possible. In lower Ruzizi plant development was limited by low rainfall (670, 4 mm per year and soils with a low water retention capacity (sand dunes. For this region, it is necessary to identify cultivars resistant to drought and devise a method of establishing these cultivars on sand dunes.

    Full Text Available Abstract Background Recent advances in sequencing technologies have enabled generation of large-scale genome sequencing data. These data can be used to characterize a variety of genomic features, including the DNA copy number profile of a cancer genome. A robust and reliable method for screening chromosomal alterations would allow a detailed characterization of the cancer genome with unprecedented accuracy. Results We develop a method for identification of copy number alterations in a tumor genome compared to its matched control, based on application of Smith-Waterman algorithm to single-end sequencing data. In a performance test with simulated data, our algorithm shows >90% sensitivity and >90% precision in detecting a single copy number change that contains approximately 500 reads for the normal sample. With 100-bp reads, this corresponds to a ~50 kb region for 1X genome coverage of the human genome. We further refine the algorithm to develop rSW-seq, (recursive Smith-Waterman-seq to identify alterations in a complex configuration, which are commonly observed in the human cancer genome. To validate our approach, we compare our algorithm with an existing algorithm using simulated and publicly available datasets. We also compare the sequencing-based profiles to microarray-based results. Conclusion We propose rSW-seq as an efficient method for detecting copy number changes in the tumor genome.

    At present, the SW Iberian margin is located along the convergent Iberia-Nubia plate boundary. In Mesozoic times, the margin was located at the triple junction of the Ligurian Tethys, Central Atlantic and Northern Atlantic. The characterization of its crustal structure has allowed us to propose a configuration for this triple junction and to determine the role that this transform margin played within the plate kinematic system. In this paper we present an integrated study based on the interpretation of a 2D regional multichannel seismic survey consisting of 58 profiles, tied with onshore geology and exploratory wells, and on gravimetric modeling performed over four NW-SE trending profiles. Integrated interpretation of MCS data combined with 2D gravity modeling reveals a complex pattern in the southward crustal thinning of SW Iberia and supports the possible presence of oceanic crust under the Gulf of Cadiz. The tapering of Iberian crust is characterized by steps with rapid changes in the thickness of the crust, and thinning to Bank. Margin inversion and the pre-existing extensional crustal structure are responsible for the areal distribution and amplitude of the prominent positive gravity anomaly observed in the Gulf of Cadiz.

    Full Text Available After the incursion of the digitalisation and the Internet, new forms of cultural production, reception and consumption have come via the hands of technological convergence and the way society has adapted to that scenario. In the current context of globalisation traditional cultural conceptualisation has been modified by opening up an economic discourse based on knowledge, creativity and innovation. But how are cultural policies bringing this paradigm into their protection framework? As part of the cultural activity, cinema plays a core role contributing to the national economic competitiveness and social cohesion. However, small cinemas struggle and films made in minority languages face a lot more difficulties. This paper shows how a legal change has made a certain funding model possible for cinema in the Basque-language, suggesting that a legally binding space where a specific cultural subject is primarily recognised has become crucial for films in Basque. Tras la llegada de la digitalización e Internet, han surgido nuevas formas de producción, recepción y consumo de cultura, de la mano de la convergencia tecnológica y la forma en la que la sociedad se ha adaptado a ese escenario.

    Chronic obstructive pulmonary disease (COPD) is a prevalent condition in adults aged ≥40 years characterized by progressive airflow limitation associated with chronic inflammatory response to noxious particles in the airways and lungs. Smoking, genetics, air pollution, nutrition and other factors may influence COPD development. Most hospitalizations and deaths for COPD are caused by its acute exacerbations, which greatly affect the health and quality of life of COPD patients and pose a high burden on health services. The aims of this project were to identify trends, geographic patterns and risk factors for COPD exacerbations, as revealed by hospitalizations and deaths, in the Basque Country, Spain, over a period of 12 years (2000-2011). Hospitalization and mortality rates for COPD were 262 and 18 per 100,000 population, respectively, with clusters around the biggest cities. Hospital mortality was 7.4%. Most hospitalized patients were male (77.4%) and accounted for 72.1% of hospital mortality. Hospitalizations decreased during the study period, except for 50-64 year-old women, peaking significantly. Using a multivariate modeling approach it was shown that hospitalizations were positively correlated with increased atmospheric concentrations of NO2, CO, PM10, and SO2, and increased influenza incidence, but were negatively associated with increased temperatures and atmospheric O3 concentration. COPD exacerbations decreased in the Basque Country during 2000-2011, but not among 50-64-year-old women, reflecting the high smoking prevalence among Spanish women during the 1970-1990s. The main metropolitan areas were those with the highest risk for COPD exacerbations, calling attention to the role of heavy car traffic. Influenza virus, cold temperatures, and increased atmospheric NO2, CO, PM10, and SO2 (but decreased O3) concentrations were identified as potential contributors to the burden of COPD exacerbations in the community. These findings are important for both the

In January 2012, a retrospective observational study was carried out, with the aim of describing the characteristics of the service and determining if the new social service and the associated socio-health co-ordination had produced any effect on the use of healthcare resources by end-of-life patients. The results of a comparison of a cohort of cases and controls demonstrated evidence that the program could reduce the use of hospital resources and promote the continuation of living at home, increasing the home-based activity of primary care professionals. The objective of this study is to analyse whether a program of social intervention in palliative care (SAIATU results in a reduction in the consumption of healthcare resources and cost by end-of-life patients and promotes a shift towards a more community-based model of care. Method/design Comparative prospective cohort study, with randomised selection of patients, which will systematically measure patient characteristics and their consumption of resources in the last 30 days of life, with and without the intervention of a social support team trained to provide in-home end-of-life care.

    Multi-channel seismic and gravity anomaly data have been used to determine the extent of compressional deformation along the SW Portugal rifted continental margin and place constraints on the long-term (> 1 M.a.) strength of the lithosphere. The seismic sections suggest that the region of compressional deformation is broad (˜ 100 km) and has been active since the Miocene. Integration with recently compiled high-resolution bathymetric data shows that the main thrust front is located along the base of the continental slope, between north of the Gorringe Bank and the Setúbal Canyon. Gravity data show that the thrust front is associated with a narrow isostatic anomaly 'high' of up to 70 mGal that is flanked on its NW edge by a broad 'low' of up to 20 mGal. This high-low 'couple' can be explained by compressional loading of extended continental lithosphere that increased its flexural strength (or equivalent elastic thickness, Te) since rifting. Based on combined 2-D backstripping and gravity modelling techniques we estimate a Te of ˜ 10 km during the main stretching episode, in the Late Jurassic (maybe earliest Cretaceous?), and of 35-50 km during the Miocene to Recent compression. The existence of a broad region of deformation off SW Portugal together with a strong lithosphere have implications for the rupture models of large earthquakes in the region, such as the 1755 Great Lisbon earthquake, particularly when accounting for a complex, multiple rupture in faults which cut through lithosphere of distinct nature and origin, as appears to be required by modellers to explain the historical observational data.

    2012-08-01

    The community of aquatic hyphomycetes associated with decomposing alder leaf litter was studied during autumn-winter in nine headwater reference streams of the Basque Country (northern Spain). In order to study the spatial variability in composition and community structure, three streams from each of three different river basins were compared. The colonization dynamics and community changes throughout the decomposition process were also followed in three of the rivers (one per basin). The taxonomic richness and community structure of these fungi varied among rivers, including similar streams of a given watershed. However, neither species diversity nor total abundance was statistically related to environmental variables. Only the conidial production of two of the species, Flagellospora curvula and Lunulospora curvula appeared to be enhanced by nitrate availability in the water. The taxonomic richness and the reproductive activity (sporulation rate) were positively related to the leaf litter decomposition rate. The changes in conidial production along the process were similar for all the streams and helped explain leaf litter quality dynamics.

    Purpose. The purpose of this study was to assess the feasibility of the Spanish Diabetes Self-Management Program (SDSMP) in the primary care setting of the Basque Health Service and offer initial estimations of the randomized controlled trial (RCT) effects. Methods. Ten health centers (HCs) participated in a single-arm pilot study with a 6-month follow-up period between February 2011 and June 2012. Recruitment was performed via invitation letters, health professionals, and the local media. Each intervention group consisted of 8–15 people. The ability of each HC in forming up to 2 groups, participants' compliance with the course, and coordination and data collection issues were evaluated. Glycated haemoglobin (HbA1c) was the main outcome variable. Secondary outcomes were cardiovascular risk factors, drugs consumption, medical visits, quality of life, self-efficacy, physical exercise, and diet. Results. Two HCs did not organize a course. A total of 173 patients initiated the program, 2 dropped out without baseline data, and 90% completed it. No pre-post HbA1c differences existed. Certain improvements were observed in blood pressure control, self-efficacy, physical activity, and some dietary habits. Conclusion. The SDSMP is feasible in our setting. Our experience can be of interest when planning and conducting this program in similar health settings. The trial is registered with ClinicalTrials.gov identifier NCT01642394. PMID:28119932

    Levels of imposex (superimposition of male characters, upon females) and the presence of sterile females are assessed in the gastropod Nassarius nitidus (Jeffreys, 1867), at 22 locations in the Basque Country (northern Spain). At 18 of these localities, butyltin bioaccumulation (tributyltin (TBT); dibutyltin; monobutyltin) was analysed using isotope dilution and GC-ICP-MS. Higher imposex levels and TBT body burden were found in confined harbours, with a large vessel traffic or the presence of a fishing fleet or a shipyard. For the first time, four apparently sequential types of aborted capsules are described in this species. Another novelty is the interspecific comparison between imposex intensities in sympatrically living populations of N. nitidus and N. reticulatus. This showed that sensitivity to TBT pollution of both species is relatively similar (in terms of Relative Penis Length Index). Since N. nitidus has a restricted habitat distribution due to its low presence in wave-exposed habitats, its complementary use with other species is recommended for its use in TBT monitoring programmes.

    Ichnological analysis was conducted in the Danian-Selandian (D-S) boundary interval from the Sopelana section (Basque Basin, northern Spain) to improve characterization of the recently defined Global Stratotype Section and Point of the base of the Selandian Stage (Middle Paleocene) in the nearby Zumaia section, and to interpret the Danian-Selandian boundary event with its associated palaeoenvironmental changes. The trace fossil assemblage of the boundary interval is relatively scarce and shows low diversity, consisting of Chondrites, Planolites, Thalassinoides, Trichichnus and Zoophycos, which cross-cut a diffuse, burrow-mottled background, typical of a normal burrowing tiered community. Distribution of trace fossils shows local drops in abundance and diversity just above the D-S boundary and about half a metre upwards into the succeeding Selandian. Generally, the Selandian part of the section has slightly lower trace fossil diversity and abundance. This is interpreted as due to a higher detrital food supply, corresponding to a sea-level fall, in contrast to a decreased food supply during the Selandian sea-level rise. Smaller-scale fluctuations of trace fossil diversity and abundance are also interpreted as due more to food content fluctuations in the sediment than to oxygenation of pore waters. Results reveal the minor influence of an extreme warming event (hyperthermal conditions) at the D-S boundary which affected the whole benthic habitat. Contrarily, a probable major effect of sea-level fluctuations can be envisaged, which determined variations in siliciclastic input and food content.

    To find the implantation and quality of clinical practice guidelines (CPG) to manage the major cardiovascular risks: tobacco dependency, hypertension, hyperlipaemia and diabetes mellitus. To work out a model to evaluate the quality of the CPG in primary care. Cross-sectional descriptive study. The primary care centres of the Basque Country. 170 CPG used at present to manage the four mentioned cardiovascular risks. Information was requested on the use of CPG and copies of their guidelines were requested from those in charge of 103 ranked centres. 77 centres replied (76%), of which 66 said they used one of them. A total of 170 CPG were received. On the basis of non-specific prior proposals for primary care, 21 quality criteria for the CPG, grouped in 6 blocks, were drawn up. Top quality was found in the block for clarity of clinical procedure with 63% compliance with the CPG, followed by general description (54%), and evaluation and measurement of impact (30%). The blocks with worst compliance were identification of people involved in their design (23%), evidence of their recommendations (19%) and conditions of application (4%). A model was proposed to evaluate the quality of the CPG. Major deficiencies in quality were found. These were most marked in key aspects such as bibliographic support for their recommendations, envisaging of conditions for application and identification of authors and reviewers.

    Full Text Available Some relict populations of the native crayfish Austropotamobius pallipes have been located in rivers in Bizkaia, (Basque Country, Spain, and its population numbers and dynamics, and habitat conditions have been studied for three years. The first descriptive results are given in this paper. The native crayfish populations must be considered residual because of the disrupted area distribution and highly fluctuating demography of the species. Up to now, the species has been located in more than thirty fluvial areas of relatively high slope and shallow and good quality water. Population characteristics (sex ratio, length and weight relations and length frequency classes are studied in nineteen cases. Maximal relative population numbers are about 100 captures per hour ; these values are correlated to variables of conductivity, hardness, and concentrations of nitrates, nitrites, magnesium, potassium and ammonium. The degree of mineralization must reach a minimum level and, within the values found in the studied rivers, its increase favours the population of crayfish. Management measures to conserve native crayfish must include the protection and improvement of their habitat, prevention of access to it and to the commencement of a genetic study to palliate the phenomenon of endemism. It would also be highly recommendable to begin experimental restocking of riverbeds now without crayfish fauna and with apparently optimum conditions for the establishment of populations of autochthonous crayfish.

    Breadfruit (Artocarpus communis Moraceae) is cultivated in tropical and subtropical regions as a traditional starch crop and also has potential medicinal properties. The aim of this work was to study the in vitro anticancer activity of compounds isolated from the leaves of Artocarpus communis. Three new geranyl chalcone derivatives including isolespeol (1), 5'-geranyl-2',4',4-trihydroxychalcone (2), and 3,4,2',4'-tetrahydroxy-3'-geranyldihydrochalcone (3), together with two known compounds lespeol (4) and xanthoangelol (5), were isolated from the leaves of Artocarpus communis. The structures of 1- 5 were elucidated by spectroscopy and through comparison with data reported in the literature. The effects of geranyl chalcone derivatives (1- 5) on the viability of human cancer cells (including SW 872, HT-29, COLO 205, Hep3B, PLC5, Huh7, and HepG2 cells) were investigated. The results indicate that isolespeol (1) showed the highest inhibitory activity with an IC 50 value of 3.8 muM in SW 872 human liposarcoma cells. Treatment of SW 872 human liposarcoma cells with isolespeol (1) caused the loss of mitochondrial membrane potential (DeltaPsim). Western blotting revealed that isolespeol (1) stimulated increased protein expression of Fas, FasL, and p53. The expression ratios of pro- and antiapoptotic Bcl-2 family members were also changed by isolespeol (1) treatment to subsequently induce the activation of caspase-9 and caspase-3, which was followed by cleavage of poly (ADP-ribose) polymerase (PARP). These results demonstrate that isolespeol (1) induces apoptosis in SW 872 cells through Fas- and mitochondria-mediated pathways.

    We present an analysis of time-resolved, medium resolution optical spectroscopic observations of UX UMa in the blue (3920-5250 A˚) and red (6100-7200 A˚) wavelength ranges in April 1999 and March 2008, respectively. UX UMa has been in different states during those observations. Doppler tomography method was used to accretion disc structure investigation in both states. During the observations in 1999, UX UMa showed many of the defining properties of the SW Sex stars. However, all these features almost completely disappeared in 2008. We have also estimated the radial velocity semi-amplitude K1.

    The pre-Mesozoic geodynamic evolution of SW Iberia has been investigated on the basis of detailed structural analysis, isotope dating, and petrologic study of high-pressure (HP) rocks, revealing the superposition of several tectonometamorphic events: (1) An HP event older than circa 358 Ma is recorded in basic rocks preserved inside marbles, which suggests subduction of a continental margin. The deformation associated with this stage is recorded by a refractory graphite fabric and noncoaxial mesoscopic structures found within the host metasediments. The sense of shear is top to south, revealing thrusting synthetic with subduction (underthrusting) to the north. (2) Recrystallization before circa 358 Ma is due to a regional-scale thermal episode and magmatism. (3) Noncoaxial deformation with top to north sense of shear in northward dipping large-scale shear zones is associated with pervasive hydration and metamorphic retrogression under mostly greenschist facies. This indicates exhumation by normal faulting in a detachment zone confined to the top to north and north dipping shear zones during postorogenic collapse soon after 358 Ma ago (inversion of earlier top to south thrusts). (4) Static recrystallization at circa 318 Ma is due to regional-scale granitic intrusions.

    Full Text Available La chute du mur de Berlin et l’effondrement des régimes communistes eurent pour effet de discréditer et affaiblir de nombreux mouvements révolutionnaires, et de provoquer l’émergence ou la résurgence de mouvements nationalistes.En 1989-90, deux conflits violents faisaient rage au cœur de l’Europe occidentale démocratique, en Irlande du Nord et au Pays Basque.Dans ces deux territoires, des nationalistes, dont certains étaient des radicaux animés par des revendications nationalistes et révolutionnaires s’opposèrent à des états démocratiques par l’utilisation de la violence. Un processus de paix se développa à partir de 1998 en Irlande du Nord ; celui du Pays Basque est toujours dans l’impasse.Il semble au premier abord que ces conflits continuèrent sans bouleversement majeur dans la période qui suivit la chute du mur.Cet article examine les revendications des nationalistes en Irlande du Nord et au Pays Basque pour tenter de dévoiler dans quelle mesure ils furent affectés par ce choc historique.Une perspective comparative permet de comprendre que ces mouvements furent influencés différemment en fonction des contextes locaux. Certains acteurs politiques restèrent volontairement imperméables, alors que d’autres furent davantage affectés par le débat idéologique.

    Inbreeding patterns over the past two centuries have been studied more extensively in Spain and Italy than anywhere else in Europe. Consanguinity studies in mainland Spain have shown that populations settled along the Cantabrian cornice share inbreeding patterns that distinguish them from other populations further south. A visual representation of spatial variations of two key inbreeding variables is presented here for the first time via contour maps. This paper also analyzes time trends of mean inbreeding coefficients for X-linked (F(x)) and autosomal genes (F) (1862-1995) together with variations in F(x)/F ratios in Guipúzcoa, the most autochthonous Spanish Basque province. Because close cousin marriages are a mark of identity of the study population, we evaluated the contribution of uncle-niece/aunt-nephew (M12) and first cousin (M22) marriages to F(x) and F values and compared the frequencies of M12 and M22 pedigree subtypes and their corresponding F(x)/F ratios to those found in other Spanish populations. The mean Fx and F inbreeding levels in Guipúzcoa for the 134-year period analyzed were 1.51 x 10(-3) and 1.04 x 10(-3), respectively, and the F(x)/F ratio was seen to be very stable over time. Our findings show that major similarities exist for close consanguineous marriage subtypes between Basque and non-Basque Spanish populations, despite significant geographic variability in terms of first cousin pedigrees. The distortion seems to be caused by Guipúzcoa. The F(x)/F ratios for first cousins in Spanish populations were higher than expected (1.25), with values ranging from 1.34 to 1.48. The findings of the present study may be useful for advancing knowledge on the effects of the interaction between biology and culture and for exploring associations between mating patterns and the prevalence of certain diseases.

    To understand certain outstanding aspects of the life of the Basque surgeon and urologist Julián Guimón Rezola. His personal and bibliographic documentary legacy helps reconstruct his works and personal character. We analysed the written works of Julián Guimón Rezola and a collection of documents, letters, photographs, illustrations and objects from his personal and professional life, accessed through his family. We analysed the content of the author's main publications and related the documents to historic facts. Julián Guimón Rezola was an upstanding individual, a father, a family man and a nationalist before the struggle, who was dedicated to his work and particularly to teaching and health management. He started his urological career under the direction of Francisco Pérez Andrés in the Santo Civil Hospital of Bilbao. He endured unjust repression for participating in the creation of the Basque University in 1936. Sentenced to life imprisonment, he stated a new life as a reclusive surgeon in the prison of Puerto de Santa María. He was pardoned three years later but was deprived of all his offices and disqualified from civil service. He founded his clinic and maintained his training in the United States. He presided over the Medical-Surgical Insurance Group of Bilbao (Igualatorio Médico-Quirúrgico) and, on 2 occasions, the Bilbao Academy of Medical Sciences. He was considerably active professionally and focused on social medicine and modern urology. He wrote 104 scientific articles, a number of which were of considerable quality and impact. We observed an evolution in the subject matter of these articles, all with exquisite professionalism and humanity. He corresponded with renowned practitioners and was admitted to the Spanish Royal National Academy of Medicine in 1970. He ended his career with an appointment as honorary professor at the University of the Basque Country 2 years before his death. Surgeon urologist Julián Guimón Rezola was a

    We examine the performance of high technology based SMEs located in the three Science Parks of the Basque Country. Our findings suggest that intangible assets representing the human capital and organizational learning capacity of firms are positively related to business growth. We found that about 80% of sample firms established a collaborative agreement with partner firms. Results show that the formation of a larger number of formal alliances with R and D firms (i.e., universities, innovation centers) was positively associated with firm growth. (Author) 21 refs.

  17. Present-day strain partitioning and strain transfer across the Fairweather and Denali Faults in SW Yukon - SE Alaska

    In SW Yukon - SE Alaska, the present-day Pacific - North America relative motion is highly oblique to the main plate boundary, resulting in strong strain partitioning tectonics that link the Aleutian subduction to the west to Queen-Charlotte transform to the south. This transition region is also the site of present-day orogeny and accretion of the allochthonous Yakutat Terrane to the Northern Cordillera. We present results from new campaign and permanent GPS stations deployed in SW Yukon, combined with STEEP data from SE Alaska, straddling the Fairweather and Denali Faults. GPS data are processed with the NRCan PPP software to derive long-term velocities and are corrected for transient effects primarily due to Glacial Isostatic Adjustment to recent ice mass loss. In the southern region (from Yakutat, AK to Whitehorse, YK), our preferred model gives slip rates of 49.9 +/- 2.6 mm/a on the Fairweather Fault and 1.1 +/- 1.0 mm/a on the Denali Fault; i.e., over 95% the Pacific - North America strike-slip motion is accommodated on the main plate-boundary fault. However, the fault-normal component is strongly partitioned, with ~25% of the Pacific - North America convergence transferred inland, into the Yukon and Northern Cordillera. This strain transfer could explain the seismicity observed in the Mackenzie Mountains 500 - 800 km from the coast. In the northern region (from Yakutat, AK to Beaver Creek, YK), the Pacific - North America convergence is strongly partitioned, with less than ~60% accommodated on the Chugach-St. Elias Fault and the residual motion distributed between the Pamplona thrust zone to the south (~15%) and internal shortening of the St. Elias Mountains to the north (~25%), where few faults and little seismicity are observed. The new GPS data also helps address the activity and slip rate of a potential "Connector Fault" that would link the Fairweather and Totschunda Faults, bypassing the Denali Fault in SW Yukon.

    We present $Spitzer$/IRS mid-infrared spectral maps of the Galactic star-forming region M17 as well as IRSF/SIRIUS Br$\\gamma$ and Nobeyama 45-m/FOREST $^{13}$CO ($J$=1--0) maps. The spectra show prominent features due to polycyclic aromatic hydrocarbons (PAHs) at wavelengths of 6.2, 7.7, 8.6, 11.3, 12.0, 12.7, 13.5, and 14.2 $\\mu$m. We find that the PAH emission features are bright in the region between the HII region traced by Br$\\gamma$ and the molecular cloud traced by $^{13}$CO, supporting that the PAH emission originates mostly from photo-dissociation regions. Based on the spatially-resolved maps, we examine spatial variations of the PAH properties in detail. As a result, we find that the interband ratio of PAH 7.7 $\\mu$m/PAH 11.3 $\\mu$m varies locally near M17SW, but rather independently of the distance from the OB stars in M17, suggesting that the ionization degree of PAHs is mainly controlled by local conditions rather than the global UV environments determined by the OB stars in M17.

    Full Text Available This article offers an analysis of the process of criminalization, which, in the authors’ opinion, the Basque Ecologist Movement (BEM has suffered in its fight against the High Speed Train (HST. The text is structured in five sections. The initial section highlights the main characteristics of the BEM from its origins to the present, indicating the importance in its development of the Basque national question and political violence on one side, and a combined discourse that is at once local and global on the other. The second section provides data referring to the HST project, indicating its political and socio-economic impacts, while the third section is dedicated to clarifying the main identity features and lines of action of the anti-HST movement. The fourth section shows both the repertory of collective action of the opponents of the HST and the policies of repression and criminalization exercised against them. The fifth and final section is situated in today’s new political cycle, which follows the end of ETA’s armed activity and sets out possible future scenarios. Rather than an academic article consisting of intellectual reflection, this article is intended as a political testimony of the long struggle of this social movement, involving 20 years of ecologist activism, a struggle that continues today, since the infrastructure project is still in force, although the conflict is little known at the international level.

    Full Text Available As part of the Millennium Ecosystem Assessment in Biscay, Basque Country, we described scenarios for Biscay through 2050 in an integrated and participatory way by downscaling the Millennium Ecosystem Assessment (MA global scenarios, analyzed how ecosystem services and human well-being might change in a range of plausible futures, identified management strategies for the territory through a backcasting process, and explored the relevance of scenarios to policy making. Our intention was to strengthen the link to policy making and to achieve a real implementation of our research results in ecosystem management policies. We also aimed to provide more insights on how large-scale scenario developments can be translated to the local level. In doing so, we emphasized specific local characteristics and used highly participatory methods focusing on novel elements, such as organizing back-to-back workshops, creating coherent scenarios across scales, using visual elements to present exploratory scenarios, and combining exploratory scenarios with normative backcasting using a World Café methodology. The outcome scenarios and management proposals are relevant for decision making and planning processes at local scale and at the same time, they are comparable to other assessment scenarios. This local participatory scenario process and tool for landscape planning is already having a policy impact thanks to the involvement of public administration technicians and policy makers. In the recently renewed strategic policy plan for sustainability of the county, this assessment is considered a high priority. Therefore, for the next steps of the assessment, detailed guidelines for ecosystem management policies are planned.

    Full Text Available As it is happening with all mass media, the future of local televisions inevitably depends on the Internet. Local media have found in the new technologies a way to defy their natural communication space. Thanks to Internet, territory disappears as a geographical limit; it allows local media to reach a wider audience, placing them alongside large media companies and increasing their competition chances. For this reason, in recent years many television stations have shown an interest in this area and have developed a website. In this investigation the authors analyze the presence of local television stations of the Basque Country in the Web and study whether they fully exploit the resources at their disposal in the cyberspace.El futuro de las televisiones locales, al igual que el de todo medio de comunicación, pasa necesariamente por estar presente en Internet. Estos pequeños medios locales encuentran en las nuevas tecnologías una manera de superar su espacio de comunicación original. No sólo el territorio, como límite geográfico, deja de ser una desventaja sino que las emisoras locales que saltan a la Red tienen acceso de esta forma a una audiencia potencial que no tiene nada que envidiar a la de las grandes empresas de comunicación, lo que les permite competir en mejores condiciones. De esta forma, en los últimos años muchas emisoras locales han mostrado su interés en el medio y han desarrollado un sitio web. Este artículo estudia la presencia de las televisiones locales del País Vasco en la Red y el grado de aprovechamiento que hacen de las posibilidades que les ofrece el medio digital.

    [corrected] To assess the body image perception and to compare the results with the true measurements in a group of university students. Participants were 28 volunteer females recruited from the degree in Human Nutrition and Dietetic from the University of the Basque Country (Spain). All participants gave their informed consent. The mean (SD) age of the participants was 22.01 (2.12) years (20,23-28,25). Anthropometric measurement estimated directly and the derived indexes were compared with reference values. The assessment of body image perception was made using a somatomorphic software. The difference between the perceived measurements and the ideals were used as measure of body dissatisfaction. Data were analyzed using SPSS vs 14.0. Prevalence of overweight and obesity was 10.7%, and of under-weight was 70.1%. The body fat perception was well, while the perception of the muscle index was significantly different from the real measure (3.91+/-2.75 kg/m2; P<0.001). The level of body dissatisfaction was higher for the body fat (6.00+/-8.61%; P<0.001) than for the muscle index (1.65+/-2.82 kg/m2; P<0.01). This result can be justified for the present canons of beauty and for the overvaluation of the thinness. Additional research is needed to further know the relation between female body image and true measurements of body composition. Future research will allow to compare the results with other populations.

    In natural languages some syntactic structures are simpler than others. Syntactically complex structures require further computation that is not required by syntactically simple structures. In particular, canonical, basic word order represents the simplest sentence-structure. Natural languages have different canonical word orders, and they vary in the degree of word order freedom they allow. In the case of free word order, whether canonical word order plays any role in processing is still unclear. In this paper, we present behavioral and electrophysiological evidence that simpler, canonical word order preference is found even in a free word order language. Canonical and derived structures were compared in two self-paced reading and one ERPs experiment. Non-canonical sentences required further syntactic computation in Basque, they showed longer reading times and a modulation of anterior negativities and P600 components providing evidence that even in free word order, case-marking grammars, underlying canonical word order can play a relevant role in sentence processing. These findings could signal universal processing mechanisms because similar processing patterns are found in typologically very distant grammars. We also provide evidence from syntactically fully ambiguous sequences. Our results on ambiguity resolution showed that fully ambiguous sequences were processed as canonical sentences. Moreover, when fully ambiguous sequences were forced to complex interpretation by means of the world knowledge of the participants, a frontal negativity distinguished simple and complex ambiguous sequences. Thus the preference of simple structures is presumably a universal design property for language processing, despite differences on parametric variation of a given grammar.

  4. Enhanced Southern Westerly Activity During the Last Glacial Interglacial Transition in SW Patagonia

    Much of the ongoing controversy regarding synchrony or bipolar asynchrony has centered on the timing and structure of temperature changes during the Last Glacial Interglacial Transition (LGIT) in the southern mid- latitudes, in particular the Patagonian region (40°-56°S) of South America. South America is the only continuous continental landmass in the Southern Hemisphere that intersects the entire westerly wind belt and lies in the critical climatic interface between mid- to high latitudes. The region between 50°- 55°S is of particular interest considering its proximity to the polar front and the southern margin of the westerly winds, and the possibility of monitoring paleoclimate changes at or near this important oceanic- atmospheric boundary. Present and past climate studies, including modeling simulations, have emphasized that interactions between changes in the Antarctic Circumpolar Current, the southern westerly winds, sea ice, and the polar front are important drivers for deep ocean circulation changes, variations in atmospheric CO2, and equator-to-pole temperature and pressure gradients. Yet, the behavior of the westerly winds and the adjacent Southern Ocean during the LGIT is still poorly understood despite their fundamental influence on modern hemispheric and global climate. In this study we compare sediment cores from small closed-basin lakes and a bog from the Ultima Esperanza area of SW Patagonia (52°S), an area affected solely by the southern westerlies. Lake sediment cores from three lakes show lacustrine sedimentation over the last 17,000 years. In contrast, the Dumestre bog shows subaerial peat deposition since 15 ka interrupted by a prominent lacustrine phase dated between 14.5-11.5 ka. During this interval palynological records indicate the preponderance of cold-resistant herbs, along with aquatic taxa, followed by a rapid expansion of Nothofagus woodlands/forests, a lake regressive phase in Dumestre, and disappearance of laminated calcite

    SW Anatolian tectonics are dominated mainly by emplacement of Lycian Nappes from north to south over the Beydaǧları platform during the early to middle Miocene, which followed by the development of the so called Fethiye Burdur Fault Zone (FBFZ). This fault zone is supposed to be a sinistral strike-slip fault zone that accommodated more than 100 km displacement between the Menderes Massif and the Beydaǧları platform during the exhumation of the Menderes Massif, mainly during the late Miocene. In addition, the FBFZ is collinear with the on-land NE continuation of the Pliny Trench along which the north subducting African slab is thought to be torn apart and retreated from somewhere around the apex of Isparta Angle to its present configuration as a STEP fault. In order to test already proposed evolutionary scenarios, and the feasibility of a STEP fault scenario and tectonic evolution of the region, we have conducted a rigorous paleomagnetic and kinematic study in the region containing more than 3000 paleomagnetic samples collected from 88 locations distributed evenly all over SW Anatolia and more than 2000 fault slip data measured mainly along the FBFZ. According to our preliminary results, except for some local insignificant clockwise rotations - the region underwent counter-clockwise rotation during the early to Late Miocene. The rotation senses and amounts are almost the same everywhere implying that rotation took place uniformly everywhere, as a rigid body rotation or the region underwent no internal rotational deformation. Likewise, rotations in the west and the east of FBFZ are similar for the post-late Miocene implying no internal rotational deformation. In addition to paleomagnetic data, the slickenside pitches and constructed paleostress configurations mainly along the FBFZ indicated that the faults within the FBFZ are mainly normal in character although minor lateral components are observed at the fault terminations or intersections. These fault slip

    Motion of the Arabian plate with respect to Eurasia has been remarkably steady over more than 25 Myr as revealed by comparison of geodetic and plate tectonic reconstructions (e.g., McQuarrie et al., 2003, GRL; ArRajehi et al., 2010, Tectonics). While internal plate deformation is small in comparison to the rate of Arabia-Eurasia convergence, the improved resolution of GPS observations indicate ~ NE-SW compressional strain that appears to affect much of the plate south of latitude ~ 30°N. Seven ~ NE-SW oriented inter-station baselines all indicated shortening at rates in the range of 0.5-2 mm/yr, for the most part with 1-sigma velocity uncertainties < 0.4 mm/yr. Plate-scale strain rates exceed 2×10-9/yr. The spatial distribution of strain can not be resolved from the sparse available data, but strain appears to extend at least to Riyadh, KSA, ~ 600 km west of the Zagros Fold and Thrust Belt that forms the eastern, collisional boundary of the Arabian plate with Eurasia (Iran). Geodetic velocities in the plate tectonic reference frame for Arabia, derived from magnetic anomalies in the Red Sea (Chu and Gordon, 1998, GJI), show no significant E-W motion for GPS stations located along the Red Sea coast (i.e., geodetic and plate tectonic spreading rates across the Red Sea agree within their resolution), in contrast to sites in the plate interior and along the east side of the plate that indicate east-directed motions. In addition, NE-SW contraction is roughly normal to ~ N-S striking major structural folds in the sedimentary rocks within the Arabian Platform. These relationships suggest that geodetically observed contraction has characterized the plate for at least the past ~ 3 Myr. Broad-scale contraction of the Arabian plate seems intuitively reasonable given that the east and north sides of the plate are dominated by active continental collision (Zagros, E Turkey/Caucasus) while the west and south sides are bordered by mid-ocean ridge spreading (Red Sea and Gulf of

    SW Yunnan of China constituted part of the northern margin of Gondwana facing the proto-Tethys ocean in the early Paleozoic. However, the evolution of the region and its relationship with the accretionary orogenism have been poorly established. This paper reports a set of new zircon U-Pb age data and whole-rock major oxides, elemental and Sr-Nd isotopic data for early Paleozoic metavolcanic rocks from the previously defined Lancang Group and reveals the development of an Ordovician suprasubduction zone in SW Yunnan. Zircon U-Pb ages of 462 ± 6 and 454 ± 27 Ma for two representative samples indicate eruption of the volcanic rocks in the Late Ordovician. Geochemical data for the metavolcanic rocks together with other available data indicate a calc-alkaline affinity with high Al2O3 (13.04-18.77 wt%) and low TiO2 (0.64-1.00 wt%). They have Mg-numbers ranging from 62 to 50 with SiO2 of 53.57-69.10 wt%, compositionally corresponding to the high-Mg andesitic rocks. They display enrichments in LREEs and LILEs with significant Eu negative anomalies (δEu = 0.20-0.33), and depletions in HFSEs, similar to arc volcanic rocks. Their initial 87Sr/86Sr ratios range from 0.721356 to 0.722521 and ɛNd(t) values from -7.63 to -7.62 with Nd model ages of 2.06-2.10 Ga. Integration of ages and geochemical data with available geological observations, we propose the presence of Ordovician magmatism related to proto-Tethyan evolution in SW Yunnan and the metaigneous rocks formed in an island-arc setting. They were part of a regional accretionary orogen that extended along the northern margin of Gondwana during Neoproterozoic to early Paleozoic period.

    Although there is considerable evidence implicating apolipoprotein E (ApoE) epsilon4 in the development of the Alzheimer's disease (AD), additional factors are also known to be involved. Thus, an association has been described between C267T polymorphism of the 5-hydroxytryptamine 6 receptor (5-HT(6)) receptor gene and AD. This case-control study analyzes the ApoE and 5-HT(6) receptor polymorphisms in 173 cases and 102 age and sex matched controls from Araba and Bizkaia (The Basque Country, Spain). The analysis of ApoE showed the frequencies of epsilon4 allele to be significantly higher in AD patients (0.292) than in the controls (0.083). When 5-HT(6) receptor polymorphism was analyzed, a greater frequency of 267C allele was observed in AD patients than in controls, though the difference was not statistically significant. Likewise regarding ApoE epsilon4 status, no statistically significant difference was observed. In conclusion, the association of ApoE epsilon4 to AD in a sample of patients from the Basque Country is confirmed, though the association to C267T polymorphism of the 5-HT(6) receptor has not been observed.

    Full Text Available Study of emotions in human-computer interaction is a growing research area. This paper shows an attempt to select the most significant features for emotion recognition in spoken Basque and Spanish Languages using different methods for feature selection. RekEmozio database was used as the experimental data set. Several Machine Learning paradigms were used for the emotion classification task. Experiments were executed in three phases, using different sets of features as classification variables in each phase. Moreover, feature subset selection was applied at each phase in order to seek for the most relevant feature subset. The three phases approach was selected to check the validity of the proposed approach. Achieved results show that an instance-based learning algorithm using feature subset selection techniques based on evolutionary algorithms is the best Machine Learning paradigm in automatic emotion recognition, with all different feature sets, obtaining a mean of 80,05% emotion recognition rate in Basque and a 74,82% in Spanish. In order to check the goodness of the proposed process, a greedy searching approach (FSS-Forward has been applied and a comparison between them is provided. Based on achieved results, a set of most relevant non-speaker dependent features is proposed for both languages and new perspectives are suggested.

    Full Text Available Population dynamics and production of a population of Streblospio benedicti from the Gernika estuary (Basque coast, Gulf of Biscay were studied monthly for one year, from May 1991 to May 1992. S. Benedicti was present in the muddy sand community of Gernika throughout the period of study except in March, when it all but disappeared. Continuous recruitment was observed throughout the year, even though it was stronger in autumn. Abundance fluctuations were principally due to the incorporation of recruits and so the highest density in Gernika was recorded in autumn, and the lowest in spring, with an annual mean of 6346 ± 4582 ind m-2. The same pattern of seasonal variation was shown in biomass: the annual mean biomass of S.benedicti in Gernika was estimated at 0.80 ± 0.54 g dry weight m-2. Secondary production was 3.57 g dry weight m-2 year, giving a P/B ratio of 4.46. S. benedicti in Gernika behaved similarly to those described for Mediterranean Streblospio populations as regards practically continuous recruitment, but the number of individuals and the annual average density were considerably lower on the Basque coast.

    In the Basque-Cantabrian Basin (Spain), normal faulting and associated folding occurred during Late Jurassic to Early Cretaceous rifting. Cenozoic Pyrenean thick-skinned transpressive inversion in the western parts of the basin preserved the first-order extensional architecture. Integration of geological maps and seismic profiles has permitted to fully constrain the style of extensional deformation and subsequent inversion in the western portion of the Basque-Cantabrian Basin. Extensional faults offset the Paleozoic basement up to Lower Triassic rocks. The presence of an efficient décollement level represented by Triassic evaporites produced the decoupling between basement rocks and the Upper Triassic to Middle Jurassic prerift cover sequence. Extensional forced folding occurred in the cover, driven by basement faulting and the migration of evaporites toward the hanging wall of the extensional faults, with salt welds developing away from them. Upper Jurassic to Lower Cretaceous syn-rift sediments deposited synchronously with forced folding, which led to the development of extensional growth geometries associated with both master faults and nearly-transverse faults. Syn-rift growth sequences are characterized by downlap and onlap relationships with the underlying prerift units, interpreted as the result of along-strike variations of master fault extensional displacement rate. Cenozoic Pyrenean contraction generated the right-lateral transpressive inversion of basement master faults and the almost dip-slip reactivation of transverse extensional faults.

    Earthquakes and submarine landslides are recurrent and widespread manifestations of fault activity offshore SW Iberia. The present work tests the effects of sea-level rise on offshore fault systems using Coulomb stress change calculations across the Alentejo margin. Large-scale faults capable of generating large earthquakes and tsunamis in the region, especially NE-SW trending thrusts and WNW-ESE trending dextral strike-slip faults imaged at basement depths, are either blocked or unaffected by flexural effects related to sea-level changes. Large-magnitude earthquakes occurring along these structures may, therefore, be less frequent during periods of sea-level rise. In contrast, sea-level rise promotes shallow fault ruptures within the sedimentary sequence along the continental slope and upper rise within distances of <100 km from the coast. The results suggest that the occurrence of continental slope failures may either increase (if triggered by shallow fault ruptures) or decrease (if triggered by deep fault ruptures) as a result of sea-level rise. Moreover, observations of slope failures affecting the area of the Sines contourite drift highlight the role of sediment properties as preconditioning factors in this region.

    Simulation of earthquake ground motions is becoming more widely used due to improvements of numerical methods, development of ever more efficient computer programs (codes), and growth in and access to High-Performance Computing (HPC). We report on how SW4 can be used for accurate and efficient simulations of earthquake strong motions. SW4 is an anelastic finite difference code based on a fourth order summation-by-parts displacement formulation. It is parallelized and can run on one or many processors. SW4 has many desirable features for seismic strong motion simulation: incorporation of surface topography; automatic mesh generation; mesh refinement; attenuation and supergrid boundary conditions. It also has several ways to introduce 3D models and sources (including Standard Rupture Format for extended sources). We are using SW4 to simulate strong ground motions for several applications. We are performing parametric studies of near-fault motions from moderate earthquakes to investigate basin edge generated waves and large earthquakes to provide motions to engineers study building response. We show that 3D propagation near basin edges can generate significant amplifications relative to 1D analysis. SW4 is also being used to model earthquakes in the San Francisco Bay Area. This includes modeling moderate (M3.5-5) events to evaluate the United States Geologic Survey's 3D model of regional structure as well as strong motions from the 2014 South Napa earthquake and possible large scenario events. Recently SW4 was built on a Commodity Technology Systems-1 (CTS-1) at LLNL, new systems for capacity computing at the DOE National Labs. We find SW4 scales well and runs faster on these systems compared to the previous generation of LINUX clusters.

    Full Text Available A general advantage in proficiency has been repeatedly reported for learners receiving Content and Language Integrated Learning (CLIL when compared to learners who only receive English lessons. However, fine-grained studies addressing the aspects which make up this general advantage are still scarce. Within this context, this paper concentrates on the morphosyntactic development of two groups of (Basque-Spanish adolescents learning English in high-school over a two-year period. One group (n= 15 received CLIL instruction and English classes while the other group (n=11 only received English classes. The results indicate a clear advantage for the CLIL group, which seems to be at a further developmental stage. Nonetheless, both groups improve over the two years and, unlike previous claims in schools, no signs of fossilization are found although inaccuracies in inflection still exist. In light of these results, the value of increasing exposure in the form of CLIL lessons in high-school is discussed.Repetidamente se ha demostrado que los alumnos en programas de Adquisición Integrada de Contenidos y Lengua Extranjera (AICLE son mejores que los alumnos que únicamente reciben clases de inglés.

Este trabajo analiza, a lo largo de dos años, el desarrollo morfosintáctico de dos grupos de adolescentes bilingües (euskera-castellano que aprenden inglés en el colegio. Un grupo (n=11 solo recibe clases de inglés mientras que el otro (n=15 también recibe clases de AICLE. Los resultados muestran que los alumnos AICLE presentan un mayor desarrollo morfosintáctico. También se muestra que ambos grupos evolucionan a lo largo de los dos años y, frente a trabajos anteriores, no hay signos de fosilización aunque los problemas flexivos persisten.

    In diapir flanks, unconformity-bounded sedimentary packages associated with gravity-driven deposits, controlled by the ratio between the rates of sediment accumulation and diapir growth can be interpreted in the context of halokinetic sequences. The Bakio Breccias Formation (Basque Country, Spain) corresponds to redeposited carbonate deposit that developed in response to the Bakio diapir growth during the Middle Albian. These deposits provide on of the rare documented example of carbonate-dominated halokinetic sequences. The Bakio Breccias Formation consists of an alternation of clast- and matrix-supported breccias, calcirudite, calcarenite and marl, deposited along the flanks of the diapir. The description and the analysis of the Bakio Breccias Formation lead to a new model for carbonate-dominated halokinetic sequences. These sequences differ from their siliciclastic counterpart because sediment accumulation rate is controlled by carbonate platform growth on the topographic relief top of the diapirs, while sediments are preferentially deposited in the mini-basins adjacent of the diapirs, in siliciclastic settings. During transgressive system tract, carbonate platform are able to keep up with the sea level rise and to aggrade on top of the diapirs, forming thick and resistant roof, which is assumed to limit the diapir growth and thus to favour the development of halokinetic sequences with low angle unconformities (wedge halokinetic sequences). During late highstand system tract deposition (and lowstand system tract if present), platform progradation results in high sediment accumulation in the adjacent depocenters, loading the autochthonous salt layer and promote diapir growth and creation of topographic relief. In addition, if the diapir roof reaches emersion, karstification of the carbonate platform top may also favour roof destruction and diapir growth. Depending on the thickness of the roof developed previously and the amplitude of the sea level fall, the

    Full Text Available In an age of changes in species’ geographical ranges, compounded by climatic and anthropogenic impacts, it become important to know which processes and factors influence plant populations and their persistence in the long term. Here we investigated dynamic and fitness components in twelve populations of Malaxis monophyllos (L. Sw., situated in different geographical (regions and ecological (type of habitat units. Although M. monophyllos is a rare species, characterized by highly fragmented, boreal-montane distribution range, in last few decades it successfully colonized secondary habitats in Polish uplands. Our results indicate that M. monophyllos is represented mainly by small populations, which annual spatial and temporal changes might be very high, what affects the ephemeral character of these populations, regardless of the region and type of habitat. This dynamic structure, in turn, is caused by intensive exchange of individuals in populations, as well as by their short above-ground life span. Despite the large range of variation in size and reproductive traits, we can distinguish some regional patterns, which indicate boreal region as the most optimal for M. monophyllos growth and persistence in the long term, and with montane and upland/anthropogenic populations, due to lower reproductive parameters, as the most threatened. Although it should be considered that anthropogenic populations, despite their lower reproductive parameters and instability in the long term, present an intermediate, geographical and ecological character, therefore they may be valuable in shaping, both M. monophyllos’ future range, as well as its potential for response on ongoing and future changes. In general, reproduction is the main factor differentiating of M. monophyllos populations in regions, and we can suspect that it may become the cause of the future differentiation and isolation of these populations, occurring with progressive range fragmentation.

  3. Neogene magmatism and its possible causal relationship with hydrocarbon generation in SW Colombia

    The Cretaceous oil-bearing source and reservoir sedimentary succession in the Putumayo Basin, SW Colombia, was intruded by gabbroic dykes and sills. The petrological and geochemical character of the magmatic rocks shows calc-alkaline tendency, pointing to a subduction-related magmatic event. K/Ar dating of amphibole indicates a Late Miocene to Pliocene age (6.1 ± 0.7 Ma) for the igneous episode in the basin. Therefore, we assume the intrusions to be part of the Andean magmatism of the Northern Volcanic Zone (NVZ). The age of the intrusions has significant tectonic and economic implications because it coincides with two regional events: (1) the late Miocene/Pliocene Andean orogenic uplift of most of the sub-Andean regions in Peru, Ecuador and Colombia and (2) a pulse of hydrocarbon generation and expulsion that has reached the gas window. High La/Yb, K/Nb and La/Nb ratios, and the obtained Sr-Nd-Pb isotopic compositions suggest the involvement of subducted sediments and/or the assimilation of oceanic crust of the subducting slab. We discuss the possibility that magma chamber(s) west of the basin, below the Cordillera, did increase the heat flow in the basin causing generation and expulsion of hydrocarbons and CO2.

    We present Spitzer/IRS mid-infrared spectral maps of the Galactic star-forming region M17 as well as IRSF/SIRIUS Brγ and Nobeyama 45 m/FOREST 13CO (J = 1-0) maps. The spectra show prominent features due to polycyclic aromatic hydrocarbons (PAHs) at wavelengths of 6.2, 7.7, 8.6, 11.3, 12.0, 12.7, 13.5, and 14.2 μm. We find that the PAH emission features are bright in the region between the H ii region traced by Brγ and the molecular cloud traced by 13CO, supporting that the PAH emission originates mostly from photo-dissociation regions. Based on the spatially resolved Spitzer/IRS maps, we examine spatial variations of the PAH properties in detail. As a result, we find that the interband ratio of PAH 7.7 μm/PAH 11.3 μm varies locally near M17SW, but rather independently of the distance from the OB stars in M17, suggesting that the degree of PAH ionization is mainly controlled by local conditions rather than the global UV environments determined by the OB stars in M17. We also find that the interband ratios of the PAH 12.0 μm, 12.7 μm, 13.5 μm, and 14.2 μm features to the PAH 11.3 μm feature are high near the M17 center, which suggests structural changes of PAHs through processing due to intense UV radiation, producing abundant edgy irregular PAHs near the M17 center.

    2009-09-01

    Mainly on the basis of seismic data, we reconstruct magnitude and timing of Miocene to Present vertical movements in the region of the Savigliano basin, an up to 4 km thick succession of Neogene to Quaternary sediments accumulated inside the Alpine arc at the western termination of the Po Plain. We focus, in particular, on the margins of the basin which are the link between the mountain range and the subsiding basin. Seismic data from these regions allow for the definition of upward and downward vertical movements (uplift-exhumation and subsidence) with a spatial and temporal resolution which cannot be attained by other methods. The eastern, southern and western margins of the Savigliano basin display very different geometries of the sedimentary bodies and, therefore, document different vertical movements during Miocene to Present times. The eastern part of the Savigliano basin, and the regions to the E, experienced subsidence followed by exhumation. The southern margin of the basin, in the Cuneo area, was much more stable with Miocene to present formations all pinching-out close to the present day outcropping position of the basement-sedimentary cover contact. In the W, seismic sections record a stage of tilting until the Burdigalian, followed by generalized subsidence which affected also the adjacent regions of the SW Alps. The overall pattern of vertical movements is essentially controlled by the NW-ward migration of a syncline-anticline couple with the synclinal axis presently located in the center of the Savigliano basin. The width of the folds is in the order of 30-60 km (1/2 wavelength). In map view, the trace of the fold axes changes from N-S in the Savigliano basin to E-W in the Alessandria basin.

    Full Text Available This paper presents the results of direct 3−D fault displacement monitoring along the northern shore of Hornsund Fjord, SW Spitsbergen, Svalbard. The fault displacements have been recorded using three permanently installed optical−mechanical crack gauges since 2009. The monitoring data from all three sites provided evidence for a remarkable slip event that lasted from September 2011 to May 2012. The cause is discussed in some detail with consideration given to both exogenic (temperature changes, surface processes and endogenic processes (isostatic rebound and regional seismicity. It is proposed that transient fault slips recorded had a tectonic origin and were caused by approximately W−E oriented compression corresponding to regional compression in the Svalbard area.

    We present updated tomographic results obtained using seismic data recorded around geothermal reservoirs located both on-land Reykjanes, SW-Iceland and offshore along Reykjanes Ridge. We gathered records from a network of 234 seismic stations (including 24 Ocean Bottom Seismometers) deployed between April 2014 and August 2015. In order to determine the orientation of the OBS stations, we used Rayleigh waves planar particle motions from large magnitude earthquakes. This method proved suitable using the on-land stations: orientations determined using this method with the orientations measured using a giro-compass agreed. We focus on the 3D velocity images using local earthquakes to perform travel time tomography. The processing includes first arrival picking of P- and S- phases using an automatic detection and picking technique based on Akaike Information Criteria. We locate earthquakes by using a non-linear localization technique, as a priori information for deriving a 1D velocity model. We then computed 3D velocity model by joint inversion of each earthquake's location and velocity lateral anomalies with respect to the 1D model. Our models confirms previous models obtained in the area, with enhanced details. In a second step, we performed inversion of the Vp/Vs ratio. Results indicate a low Vp/Vs ratio anomaly at depth suggesting the absence of large magmatic body under Reykjanes, unlike results obtained at other geothermal field, sucha as Krafla and Hengill. We discuss implications of those results in the light of recent IDDP drilling in Reykjanes.

    The Ören and Yatağan Basins in SW Turkey host several Miocene coal deposits currently under exploitation for power generation. The present study aims to provide insight into the palaeoenvironmental conditions, which controlled the formation of the Hüsamlar coal seam located in Ören Basin. The coal seam displays many sharp alternations of matrix lignite beds and inorganic, lacustrine sediment layers. The coal is a medium-to-high ash lignite (10.47–31.16 wt%, on dry basis) with high total sulphur content (up to 10 wt%, on dry, ash-free basis), which makes it prone to self-combustion. The maceral composition indicates that the peat-forming vegetation consisted of both arboreal and herbaceous plants, with the latter being predominant in the upper part of the seam. Mica and feldspars contribute to the low part of the seam; carbonates are dominant in the upper part, whereas quartz and pyrite are present along the entire coal profile. The sudden transitions of the telmatic to the lacustrine regime and reverse is attributed to tectonic movements that controlled water table levels in the palaeomire, which affected surface runoff and hence, clastic deposition.

    Objective To investigate the role of pancreatic stellate cells (PSCs) and galectin-3 (GAL-3)on the proliferation and infiltration of pancreatic cancer cell line SW1990. Methods Human pancreatic cancercell line SW1990 and PSCs were cultured in vitro. Supernatant of cultured PSCs and SW1990 cells was collected.Expressions of GAL-3 in SW1990 cells and PSCs were detected by ELISA, RT-PCR and Western blot. Theproliferation of those cultured PSCs and SW1990 cells were measured by MTT assay and flowcytometry. Infiltrationof SW1990 cells was detected by cell infiltration kit. Results SW1990 cells expressed GAL-3 and the expressionwas up-regulated by the supernatant fluid of cultured PSCs. PSCs did not express GAL-3. SW1990 cells couldstimulate the proliferation of PSCs via GAL-3. GAL-3 antibody could inhibit SW1990 cells proliferation andinfiltration, which indicated that supernatant of PSCs might stimulate the proliferation of SW1990 cells through theinteraction with GAL-3 protein. The supernatant fluid of PSCs could enhance the invasiveness of SW1990 cellsthrough the interaction with GAL-3. Conclusion GAL-3 and PSCs was involved in the proliferation andinfiltration process of pancreatic cancer.

    The Isparta Angle is an important area of SW Anatolia where extensions in all directions (N-S, NE-SW, NW-SE and E-W) meet. These extensions were determined by normal faulting structures as well as by shallow earthquakes. All extensions, except the E-W one, were attributed to the deviatoric stresses in relation to slab forces and/or extrusion of Anatolia. The moment tensor inversion of 40 shallow earthquakes which occurred in the inner part of the Isparta Angle give focal mechanisms mostly indicating normal faulting. Inversion of all focal mechanisms of the earthquakes obtained from the moment tensor inversion yields normal faulting characterized by an approximately E-W (N268°E) σ3 axis. The calculated stress ratio R is 0.6944 indicating a triaxial stress state. Commonly accepted geodynamic models for the eastern Mediterranean region do not include plate boundary forces acting in the east or west direction. Our hypothesis is that the cause of the E-W extension is the combined forces of Gravitational Potential Energy and the hot asthenosphere upwelling through a tear fault in the subducted African plate between the Hellenic and Cyprus arcs beneath the Isparta Angle.

    Methane is an abundant, inexpensive one-carbon feedstock and one of the most powerful greenhouse gases. Because it does not compete with food demand, it is considered a promising carbon feedstock for the production of valuable products using methanotrophic bacteria. Here, we isolated a novel methanotrophic bacterium, Methylomonas sp. SW1, from a sewage sample obtained from Wonju City Water Supply Drainage Center, Republic of Korea. The conditions for uracil production by Methylomonas sp. SW1, such as Cu(2+) concentration and temperature were investigated and optimized. As a result, Methylomonas sp. SW1 produced uracil from methane as a sole carbon source with a titer of 2.1mg/L in 84h without genetic engineering under the optimized condition. The results in this study demonstrate the feasibility of using Methylomonas sp. SW1 for the production of uracil from methane. This is the first report of uracil production from gas feedstock by methanotrophic bacteria.

    The studied area is located in the Abrantes (W-central Portugal) region of the Ossa Morena Zone, where the NW tip of the Tomar-Badajoz-Cordoba Shear Zone (TBCSZ) stops against the Porto-Tomar-Ferreira do Alentejo Shear Zone (PTFASZ). The TBCSZ is a WNW-ESE sinistral transpressive intra-plate Variscan flower structure, whereas the PTFASZ is N-S dextral paleotransform during the Variscan Wilson cycle in SW Iberia. The NE branch of the TBCSZ, with top to NE sense of thrusting, is characterized by the following tectonic units, from top to bottom: - Paleozoic cover: Bimodal volcanics, marbles and arkoses, metamorphosed under greenschist facies (and displaying a minor thrust at the base), inferred to be of Lower Paleozoic age by stratigraphic correlation with other sectors dated as Cambrian to Silurian in the Ossa Morena Zone. - Cadomian intermediate crust: low/intermediate pressure (~ 4 - 7 kb) retrograded granulites, including a mafic (meta-gabbroic) component that yielded metamorphic zircons dated at 539±3 Ma (Henriques et al., 2009). - Cadomian upper crust: granitic gneisses, yielding prismatic, oscillatory-zoned, igneous zircons dated at 570 Ma, and 540±5 Ma metamorphic monazites (Henriques et al., 2009). - Cadomian volcano-sedimentary sequences: Greenschist facies black phyllites and greywackes, intercalated with black chert beds and bimodal metavolcanics ("Série Negra"), which are correlated with the Neoproterozoic sequences of the Ibero-Armorican Massif. All the tectonic units are separated by top to NE thrusts, operating under ductile conditions in the upper units and under a brittle regime in the lower units; thus, inverting the inherited Cadomian crust below the basal décollement of Palaeozoic cover. The tectonic units belong to the Ossa-Morena Zone and were transported towards NE, on top of the (very low-grade) Central-Iberian Zone relative autochthon (Ediacarian/Cambrian to Lower Devonian).

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

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

    Here we report the first results of a paleoclimatic study using O- and U-Th isotopes on a stalactite from the Tchivinguiro cave (Chela Formation, SW Angola). TIMS U-Th age determinations on 10 fragments were carried-out. The stalactite rim returned an age of 4930+/-50 y, dating an interruption of calcite deposition, possibly due to the onset of a drier period. Layering in the stalactite has an average thickness of 6.4 mm. Assuming that the layers are annual, the stalactite potentially records environmental conditions from 5 to 18 ka. Further age determinations are in progress. A δ18O profile on individual layers corresponding to a time interval of 25 y centred at 6.6 ka was obtained with an ionprobe Cameca IMS 1270 in Nancy. δ18O ranges from +24.5 to +29.1 (SMOW) with an average δ18O = +26.8. The average calculated δ18O of the water from which the speleothems deposited is -3.3 assuming today annual mean temperature of the cave (18.4^oC). The measured δ18O of today water in the cave is -5.5, similar to the annual mean of the rain collected in the area during this study. To explain the difference of -2.2 δ18O units, a cooler period during calcite deposition is invoked. Assuming 13^oC as a minimum local temperature (at LGM), the δ18O of the water in equilibrium with the stalactite is -4.6. A combination of changes in moisture sources, trajectory path and local effects may explain the lighter value of the water in the cave at 6.6 ka relative to today.

    Full Text Available In the Krš Gradac section (near to Sjenica, SW Serbia, a transition of a carbonate platform to basin facies are outcropped: Norian-lower Liassic shallow-water carbonates, middle Liassic-lower Dogger Ammonitico Rosso facies, and upper Bathonian into lowermost Cretaceous deep-water radiolarites in which the carbonate graded bed and mass flow layer are intercalated. The presence of a lower Dogger condensed sequence with the Bajocian protoglobigerinid event was hitherto not evidenced. It is documented that components of a graded bed are of extrabasinal (upper Triassic-lower Tithonian carbonate platform sediments and intrabasinal (radiolarite, meta-andesite origin, indicating a tectonic event not older than the early Tithonian. This tectonic event caused the fracturing of the carbonate platform, also partly basinal area. Consequently, the age of the graded bed is not older than the lower Tithonian. In the uppermost radiolaritic sediments in the Krš Gradac section (?middle-upper Tithonian-lowermost Cretaceous, a mass flow layer appears, which contains clasts of intrabasinal origin - different radiolarites, siliceous radiolarian argillites (some of which are unconsolidated with washed radiolarians and sponge spicules in a ferruginous sediment, sandstone grains, etc. The mass flow event is estimated as Berriasian. In the Krš Gradac radiolarite succession, the authors recognized two deep-water formations, an older one, upper Bathonian-lower Tithonian, between hardground (Dogger and a graded bed, and a younger formation, which started with a graded bed. This formation, according to its stratigraphic position, corresponds to ?middle-upper Tithonian-lowermost Cretaceous.

    We use a thin-shell approximation for the lithosphere to model the neotectonics of the Gulf of Cadiz, SW Iberia margin and the westernmost Mediterranean, in the eastern segment of the Azores-Gibraltar plate boundary. In relation to previous neotectonic models in the region, we utilize a better constrained structural map offshore, and the recent GPS measurements over NW Africa and Iberia have been taken into account, together with the seismic strain rate and stress data, to evaluate alternative geodynamic settings proposed for the region. We show that by assuming a relatively simple, two-plate tectonic framework, where Nubia and Eurasia converge NW-SE to WNW-ESE at a rate of 4.5-6 mm yr-1, the models correctly predict the amount of shortening and wrenching between northern Algeria-Morocco and southern Spain and between NW Morocco and SW Iberia, as estimated from both GPS data and geological constraints. The consistency between modelled and observed velocities in the vicinity of Gibraltar and NW Morocco indicates that forcing by slab sinking beneath Gibraltar is not required to reproduce current horizontal deformation in these areas. In the Gulf of Cadiz and SW Iberia, the modelling results support a diffuse Nubia-Eurasia Plate boundary, where the convergence is accommodated along NNE-SSW to NE-SW and ENE-WSW thrust faults and WNW-ESE right-lateral strike-slip faults, over an area >200 km wide, in good general agreement with the distribution of the seismic strain rate and associated faulting mechanisms. The modelling results are robust to regional uncertainties in the structure of the lithosphere and have important implications for the earthquake and tsunami hazard of Portugal, SW Spain and Morocco. We predict maximum, long-term average fault slip rates between 1-2 mm yr-1, that is, less than 50 per cent the average plate relative movement, suggesting very long return periods for high-magnitude (Mw > 8) earthquakes on individual structures.

  14. For the peace process in the Basque Country to be successful, it is vital that authorities understand the discourses which have been used to legitimise ETA’s political violence

    In October 2011, the Basque separatist group ETA announced the cessation of its armed activities. While studies of terrorism typically focus on the consequences of violent acts, Javier Martin-Peña and Ana Varela-Rey argue that the discourses used to legitimise political violence are just as important. Without this legitimation it would be impossible for groups like ETA to carry out violent acts without alienating their own supporters.

    Lianas are important components of tropical forests and have significant impacts on the diversity, structure and dynamics of tropical forests. The present study documented the liana flora in a Chinese tropical region. Species richness, abundance, size-class distribution and spatial patterns of lianas were investigated in three 1-ha plots in tropical seasonal rain forests in Xishuangbanna, SW China. All lianas with > or = 2 cm diameter at breast height (dbh) were measured, tagged and identified. A total of 458 liana stems belonging to 95 species (ranging from 38 to 50 species/ha), 59 genera and 32 families were recorded in the three plots. The most well-represented families were Loganiaceae, Annonceae, Papilionaceae, Apocynaceae and Rhamnaceae. Papilionaceae (14 species recorded) was the most important family in the study forests. The population density, basal area and importance value index (IVI) varied greatly across the three plots. Strychnos cathayensis, Byttneria grandifolia and Bousigonia mekongensis were the dominant species in terms of IVI across the three plots. The mean aboveground biomass of lianas (3 396 kg/ha) accounted for 1.4% of the total community above-ground biomass. The abundance, diversity and biomass of lianas in Xishuangbanna tropical seasonal rain forests are lower than those in tropical moist and wet forests, but higher than those in tropical dry forests. This study provides new data on lianas from a geographical region that has been little-studied. Our findings emphasize that other factors beyond the amount and seasonality of precipitation should be included when considering the liana abundance patterns across scales.

    Aerosol properties derived from sun-photometric observations at Wuhan during a haze period were analyzed and used as input in a radiative transfer model to calculate the aerosol radiative effect (ARE) in ultraviolet (UV), visible (VIS), near-infrared (NIR), and shortwave (SW) spectra. The results showed that the aerosol optical depth (AOD) at 440 nm increased from 0.32 under clear-air conditions to 0.85 during common haze and 1.39 during severe haze. An unusual inverse relationship was found between the Ångström exponent (AE) and AOD during the haze period at Wuhan. Under high-humidity conditions, the fine-mode median radius of aerosols increased from 0.113 μm to approximately 0.2-0.5 μm as a result of hygroscopic growth, which led to increases in the AOD and decreases in the AE simultaneously. These changes were responsible for the inverse relationship between AE and AOD at Wuhan. The surface ARE in the UV (AREUV), VIS (AREVIS), NIR (ARENIR), and SW (ARESW) spectra changed from -4.46, -25.37, -12.15, and -41.99 W/m2 under clear-air conditions to -9.48, -53.96, -29.81, and -93.25 W/m2 during common hazy days and -12.89, -80.16, -55.17, and -148.22 W/m2 during severe hazy days, respectively, and the percentages of AREUV, AREVIS, and ARENIR in ARESW changed from 11%, 61%, and 28%-9%, 54%, and 37%, respectively. Meanwhile, the ARE efficiencies (REE) in SW varied from -206.5 W/m2 under clear-air conditions to -152.94 W/m2 during the common haze period and -131.47 W/m2 during the severe haze period. The smallest decreasing rate of the REE in NIR was associated with the increase of ARENIR. The weakened REE values were related to the strong forward scattering and weak backward scattering of fine aerosol particles with increasing size resulting from hygroscopic growth, while the variation of the single scattering albedo showed less impact. Source region analysis by back trajectories and the concentration weighted trajectory (CWT) method showed that black carbon came

    Objective: Side population cells (SP cells) are a new type of stem cells. They mainly express ABCG2/BCRP1 and have the ability to eliminate DNA dye Hoechst33342. Many studies showed that side population cells were able of self-renewal, differentiation and carcinogenesis in cancers. Our investigation aimed at isolation of side population cells and ABCG2 positive subpopulation from colon cancer cell line SW480 and identification of their characteristics of cancer stem cells. Methods: side population cells and non-side population cells of colon cancer cell line SW480 were isolated with DNA dye Hoechst33342 and their cell cycles were measured by flow cytometry. Expression of ABCG2 of SW480 was measured by immunohistochemistry and immunofluorescence, and its proportion was measured by flow cytometry. Results: SW480 contained 2.29% side population cells. The fraction of side population cells decreased greatly to 0.40% by treatment with verapamil. The fraction of side population cells in S-G2M cell cycle was 16.14%, which was much lower than the fraction (34.05%) of non-side population cells in S-G2M. In SW480, ABCG2 positive cells, which proportion was 9.66%, were small, circular or oval, lack of psuedopods, similar to poor differentiation. On the contrary, the ABCG2 negative cells were large, polygonal, with many psuedopods, similar to high differentiation. Conclusion: our assay identified that side population cells did exist in SW480 and had a quiescence characteristic of stem cells. ABCG2 positive subpopulation occupied about 9.66% of SW480 and may have the ability to promote cell self-renewal and inhibit cell differentiation. Therefore, to isolate ABCG2 positive subpopulation from side population cells may be an alternative to study colorectal cancer stem cells.

    The Pilchowice basanite (SW Poland) forms volcanic plug located exactly on Intrasudetic Fault, which is one of the major tectonic lines in northern part of the Bohemian Massif. It originated during the formation of Variscan Orogen and marks the contact between two different crustal domains. The basanite is rhönite-bearing (Ladenberger et al., 2005. Min.Pol-Spec. Pap.) and contains small (JoP), which is in an opposition to modal content of clinopyroxene (0-4.1 vol.%). This suggests, that clinopyroxene is a "stealth" metasomatic phase (O'Reillly and Griffin, 2013, Springer). As trace element composition of clinopyroxene shows features typical for reaction with alkaline silicate melt (negative inflection at the most incompatible trace elements) and carbonatite (Ti, Zr, Hf anomalies), we suggest that majority of xenoliths were metasomatized by the an agent being a carbonatite-silicate melt or by CO2-bearing alkaline silicate melt. Xenolith where clinopyroxene shows constant enrichment in LREE may represent a part of mantle affected by pure carbonatitic metasomatism. Xenoliths with the lowest Fo content in olivine are probably cumulates of mafic silicate melt. Intergranular aggregates originated during reaction between primary phases and infiltrating, possibly mafic melt. The "glassy patch" might be a product of complete breakdown of amphibole in upper mantle conditions (Shaw, 2009, Lithos). However, presence of rhönite in host basanite suggests that some amphibole might have been broken also in lower pressures. Chemical composition of peridotites from Pilchowice resembles that recorded by group A mantle xenoliths from Krzeniów (Matusiak-Małek et al., 2014, JoP). In Pilchowice we have described the first xenolith affected by purely carbonatitic metasomatism. We also suggest that hydrous phases might have been present in upper mantle beneath this Pilchowice, which is believed to be nominally anhydrous (Puziewicz et al., 2015, IJES, DOI 10.1007/s00531

    SW-MW Imaging Infrared Spectrometer, the Hyperspectral optical imaging instrument is envisaged to map geomorphology and mineralogy of lunar surface. The instrument is designed to image the electro-magnetic energy emanating from moon's surface with high spectral and spatial resolution for the mission duration from an altitude of 100 km. It is designed to cover 0.8 to 5 μm in 250 spectral bands with GSD 80m and swath 20km. Primarily, there are three basic optical segments in the spectrometer. They are fore optics, dispersing element and focusing elements. The payload is designed around a custom developed multi-blaze convex grating optimized for system throughput. The considerations for optimization are lunar radiation, instrument background, optical throughput, and detector sensitivity. HgCdTe (cooled using a rotary stirling cooler) based detector array (500x256 elements, 30μm) is being custom developed for the spectrometer. Stray light background flux is minimized using a multi-band filter cooled to cryogenic temperature. Mechanical system realization is being performed considering requirements such as structural, opto-mechanical, thermal, and alignment. The entire EOM is planned to be maintained at 240K to reduce and control instrument background. Al based mirror, grating, and EOM housing is being developed to maintain structural requirements along with opto- mechanical and thermal. Multi-tier radiative isolation and multi-stage radiative cooling approach is selected for maintaining the EOM temperature. EOM along with precision electronics packages are planned to be placed on the outer and inner side of Anti-sun side (ASS) deck. Power and Cooler drive electronics packages are planned to be placed on bottom side of ASS panel. Cooler drive electronics is being custom developed to maintain the detector temperature within 100mK during the imaging phase. Low noise detector electronics development is critical for maintaining the NETD requirements at different target

    Systematic K-Ar dating and geochemical analyses of Paleogene cauldrons in the Sanin Belt of SW Japan have been made to explore the relationship between the timing of their formation and the Paleogene subduction history of SW Japan documented in the Shimanto accretionary complex. We also examine the magma sources and tectonics beneath the backarc region of SW Japan at the eastern plate boundary of Eurasia. Fifty-eight new K-Ar ages and 19 previously reported radiometric age data show that the cauldrons formed during Middle Eocene to Early Oligocene time (43-30 Ma), following a period of magmatic hiatus from 52 to 43 Ma. The hiatus coincides with absence of an accretionary prism in the Shimanto Belt. Resumption of the magmatism that formed the cauldron cluster in the backarc was concurrent with voluminous influx of terrigenous detritus to the trench, as a common tectono-thermal event within a subduction system. The cauldrons are composed of medium-K calc-alkaline basalts to rhyolites and their plutonic equivalents. These rocks are characterized by lower concentrations of large ion lithophile elements (LILE) including K 2O, Ba, Rb, Th, U and Li, lower (La/Yb) n ratios, lower initial Sr isotopic ratios (0.7037-0.7052) and higher ɛNd( T) values (-0.5 to +3.5) relative to Late Cretaceous to Early Paleogene equivalents. There are clear trends from enriched to depleted signatures with decreasing age, from the Late Cretaceous to the Paleogene. The same isotopic shift is also confirmed in lower crust-derived xenoliths, and is interpreted as mobilization of pre-existing enriched lithospheric mantle by upwelling depleted asthenosphere. Relatively elevated geothermal gradients are presumed to have prevailed over wide areas of the backarc and forearc of the SW Japan arc-trench system during the Eocene to Oligocene. Newly identified Late Eocene low silica adakites and high-Mg andesites in the Sanin Belt and Early Eocene A-type granites in the SW Korea Peninsula probably formed

    To investigate changes in proliferation and apoptosis of human colon cancer SW480 cells after silencing hypoxia inducible factor-lα (HIF-1α) expression. siRNA interference technology was performed to silence the expression of HIF-1α using lipofectamine mediation to transfect siRNA into human colon cancer SW480 cells. The siRNA interfered SW480 cells were compared with a negative control group, an empty vector group, and a blank control group. Real-time PCR and Western blot were used to measure the expressions of HIF-lα protein and mRNA. MTT and flow cytometry (FCM) were used to evaluate the apoptosis and proliferation of SW480 cells. The interfered SW480 cells had a higher level of silence of HIF-lα mRNA (> 80%) compared with those of in the three control groups (P silencing promotes apoptosis and inhibits the proliferation of SW480 cells in vitro.

    AIM: To explore the antitumor bioactivity of adenovirus-mediated mutant type p27kip1 gene in a colorectal cancer cell line SW480.METHODS: We constructed recombinant adenovirus vector expressing a mutant type p27kip1 gene (ad-p27mt), with mutation of Thr-187/Pro-188 (ACGCCC) to Met-187/Ile-188 (ATGATC), and transduced into SW480 cells. Then we detected expression of p27, Bcl-2 and Bax protein in the transductants by Western blotting, cell cycle of transductants by a digital flow cytometric system, migrating potential with Boyden Chamber end SW480 tumor cell growth inhibition in vitro and in vivo.RESULTS: We found that a recombinant adenovirus vector of expressing ad-p27mt, with mutation of Thr-187/Pro-188 (ACGCCC) to Met-187/Ile-188 (ATGATC) has potent inhibition of SW480 tumor cell growth in vitro and in vivo. Furthermore, ed-p27mt induced cell apoptosis via regulating bax and bcl-2 expressions, and G1/S arrest in SW480 cells and inhibited celt migration.CONCLUSION: ad-p27mt has a strong anti-tumor bioactivity and has the potential to develop into new therapeutic agents for colorectal cancer.

  3. On The Accretion Rates of SW Sextantis Nova-Like Variables

    2009-01-01

    We present accretion rates for selected samples of nova-like variables having IUE archival spectra and distances uniformly determined using an infrared method by Knigge (2006). A comparison with accretion rates derived independently with a multi-parametric optimization modeling approach by Puebla et al.(2007) is carried out. The accretion rates of SW Sextantis nova-like systems are compared with the accretion rates of non-SW Sextantis systems in the Puebla et al. sample and in our sample, which was selected in the orbital period range of three to four and a half hours, with all systems having distances using the method of Knigge (2006). Based upon the two independent modeling approaches, we find no significant difference between the accretion rates of SW Sextantis systems and non-SW Sextantis nova-like systems insofar as optically thick disk models are appropriate. We find little evidence to suggest that the SW Sex stars have higher accretion rates than other nova-like CVs above the period gap within the same...

    The overall deliverable from the project is the design, construction and commissioning of a detention facility heating and cooling system that minimizes ownership costs and maximizes efficiency (and therefore minimizes environmental impact). The primary deliverables were the proof of concept for the application of geothermal systems for an institutional facility and the ongoing, quarterly system operating data downloads to the Department of Energy . The primary advantage of geothermal based heat pump systems is the higher efficiency of the system compared to a conventional chiller, boiler, cooling tower based system. The higher efficiency results in a smaller environmental foot print and lower energy costs for the detention facility owner, Lancaster County. The higher efficiency for building cooling is primarily due to a more constant compressor condensing temperature with the geothermal well field acting as a thermal “sink” (in place of the conventional system’s cooling tower). In the heating mode, Ground Couple Heat Pump (GCHP) systems benefits from the advantage of a heat pump Coefficient of Performance (COP) of approximately 3.6, significantly better than a conventional gas boiler. The geothermal well field acting as a thermal “source” allows the heat pumps to operate efficiently in the heating mode regardless of ambient temperatures. The well field is partially located in a wetland with a high water table so, over time, the project will be able to identify the thermal loading characteristics of a well field located in a high water table location. The project demonstrated how a large geothermal well field can be installed in a wetland area in an economical and environmentally sound manner. Finally, the SW 40th Street Thermal Energy Plant project demonstrates the benefits of providing domestic hot water energy, as well as space heating, to help balance well filed thermal loading in a cooling dominated application.

    Full Text Available Cet article explore les différentes fonctions des peintures murales en Irlande du Nord et au Pays basque. Il montre comment les peintures murales, particulièrement visibles, ont la capacité de diffuser un message en permanence. En ce sens, comme les avancées conceptuelles sur la question de l’identification nationale permettent de le définir, elles constituent un support des processus de définition et de redéfinition des références identificatoires, et elles permettent de maintenir les dynamiques de polarisation communautaire comme éléments dominants de la structuration de l’espace public. Il n’y a que peu voire pas d’espace pour d’autres représentations de la vie sociale. Les peintures murales sont un outil de légitimation de la lutte, ce qui peut provoquer adhésion, soutien, ou mobilisation. Elles actualisent et élargissent le champ des références disponibles pour les processus d’identification, et rendent ce corpus de références toujours accessible à la population. Ainsi, elles participent activement à la dynamique du conflit.This article explores the several functions of mural paintings in Northern Ireland and in the Basque Country. It shows how the murals (which are particularly visible have the capacity to broadcast a message on a permanent basis. Recent conceptual progress on the question of national identification allows defining them as a basis for processes of definitions and re-definitions of identity references; they are also a means of keeping community polarization dynamics as the dominant elements in structuring the public space. Little or no space is left for other representations of social life. Murals are a tool for legitimising the struggle, which can stimulate adhesion, support or mobilization. They update and widen the field of references available for the identification processes, and make this corpus of references ready for use at any time for the population.

    We have recently been running earthquake ground motion simulations with SW4 on the new capacity computing systems, called the Commodity Technology Systems - 1 (CTS-1) at Lawrence Livermore National Laboratory (LLNL). SW4 is a fourth order time domain finite difference code developed by LLNL and distributed by the Computational Infrastructure for Geodynamics (CIG). SW4 simulates seismic wave propagation in complex three-dimensional Earth models including anelasticity and surface topography. We are modeling near-fault earthquake strong ground motions for the purposes of evaluating the response of engineered structures, such as nuclear power plants and other critical infrastructure. Engineering analysis of structures requires the inclusion of high frequencies which can cause damage, but are often difficult to include in simulations because of the need for large memory to model fine grid spacing on large domains.

    The Cambro-Permian Wajid Group, SW Saudi Arabia, is the main groundwater aquifer in Wadi Al-Dawasir and Najran areas. In addition, it has a reservoir potentiality for oil and natural gas in Rub' Al-Khali Basin. Wajid Group divided into four formations, ascending Dibsiyah, Sanamah, Khussyayan and Juwayl. They are mainly sandstone and exposed in an area extend from Wadi Al-Dawasir southward to Najran city and deposited within fluvial, shallow marine and glacial environments. This study aims to investigate the sedimentological and stratigraphic controls on the distribution of natural fractures within Wajid Group outcrops. A scanline sampling method was used to study the natural fracture network within Wajid Group outcrops, where the natural fractures were measured and characterized in 12 locations. Four regional natural fracture sets were observed with mean strikes of 050o, 075o, 345o, and 320o. Seven lithofacies characterized the Wajid Group at these locations and include fine-grained sandstone, coarse to pebbly sandstone, cross-bedded sandstone, massive sandstone, bioturbated sandstone, conglomerate sandstone, and conglomerate lithofacies. We found that the fine-grained and small scale cross-bedded sandstones lithofacies are characterized by high fracture intensity. In contrast, the coarse-grained sandstone and conglomerate lithofacies have low fracture intensity. Therefore, the relative fracture intensity and spacing of natural fractures within Wajid Group in the subsurface can be predicted by using the lithofacies and their depositional environments. In terms of stratigraphy, we found that the bed thickness and the stratigraphic architecture are the main controls on fractures intensity. The outcomes of this study can help to understand and predict the natural fracture distribution within the subsurface fractured sandstone hosting groundwater and hydrocarbon in Wajid and Rub' Al-Khali Basins. Hence, the finding of this study might help to explore and develop the

    SHRIMP U-Pb zircon age, geochemical and Nd isotopic data are reported for the Neoproterozoic Guandaoshan pluton in the Yanbian region, SW Sichuan. This pluton is of typical I-type granite and emplaced at (857±13) Ma. Geochemical and Nd isotopic characters suggest that the pluton was generated by partial melting of pre-existing, young (late Mesoproterozoic to early Neoproterozoic) low-K tholeiitic protolith within an intraplate anorogenic setting. The Guandaoshan pluton probably records the earliest magmatism induced by the proposed ca. 860-750 Ma mantle superplume beneath the supercontinent Rodinia.

    The last appearance datum of the radiolarian Kilinora spiralis is recorded above the first appearance datum of the ammonite Ataxioceras (A.) kurisakense in the Todoro Section of the Kurisaka Formation, Southern Kurosegawa Terrane, Shikoku, SW Japan. The constraint by ammonite age prolongs the range of the Kilinora spiralis Zone, a remarkable Jurassic radiolarian zone in Japan-NW Pacific region, into the lower Kimmeridgian. The direct correlation of the Kilinora spiralis zone with the Late Jurassic ammonite faunal succession in the Kurisaka Formation will provide a clue to the still pending chronological difference between European and North American radiolarian zones.

    Full Text Available Over the years, several techniques for improving throughput of wireless communication have been developed in order to cater for the ever increasing demand of high speed network service. However, these techniques can only give little improvement in performance because packets have to be delivered as is. As such researchers have begun thinking outside the box by proposing ideas that require relay nodes to temper packets’ contents in order to improve the throughput of a network. One of the state of the art techniques in this field is called Network Coding (NC. NC is a state of the art technique that allows relay nodes linearly combine two or more packets in a way they can be recovered upon reaching their destination. However, increasing packet size increases possibility of error affecting it. In this paper, the authors decide to investigate whether adding data recovery technique can improve the performance of a network that uses network coding, if it can, by how much can it? Is it worth the trouble? In order to answer these questions, the authors carried out a quantitative analysis of throughput in a Stop-and-Wait Automatic Repeat reQuest (SW-ARQ data transmission system with Network Coding (NC and Forward Error Correction (FEC. Vandermonde matrix is chosen as the coding technique for this research because it has both NC and data recovery characteristics. Python programming language is used to develop three Discrete Event Simulations: SW-ARQ without any NC, SW-ARQ with NC and SW-ARQ with NC and FEC. The obtained results show that SW-ARQ with NC and FEC is superior to traditional SW-ARQ in terms of throughput, especially in channels with high error rates.

    Pancreatic adenocarcinoma is highly resistant to conventional therapeutics and has been shown to evade apoptosis by deregulation of the X-linked and cellular inhibitors of apoptosis proteins (XIAP and cIAP). Second mitochondria-derived activator of caspases (Smac) induces and amplifies cell death by reversing the anti-apoptotic activity of IAPs. Thus, Smac-derived peptide analogues (peptidomimetics) have been developed and shown to represent promising cancer therapeutics. Sigma-2 receptors are overexpressed in many proliferating tumor cells including pancreatic cancer. Selected ligands to this receptor are rapidly internalized by cancer cells. These characteristics have made the sigma-2 receptor an attractive target for drug delivery because selective delivery to cancer cells has the potential to increase therapeutic efficacy while minimizing toxicity to normal tissues. Here, we describe the initial characterization of SW IV-134, a chemically linked drug conjugate between the sigma-2 ligand SW43 and the Smac mimetic SW IV-52 as a novel treatment option for pancreatic adenocarcinoma. The tumor killing characteristics of our dual-domain therapeutic SW IV-134 was far greater than either component in isolation or in an equimolar mix and suggests enhanced cellular delivery when chemically linked to the sigma-2 ligand. One of the key findings was that SW IV-134 retained target selectivity of the Smac cargo with the involvement of the NF-κB/TNFα signaling pathway. Importantly, SW IV-134 slowed tumor growth and improved survival in murine models of pancreatic cancer. Our data support further study of this novel therapeutic and this drug delivery strategy because it may eventually benefit patients with pancreatic cancer.

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

    Full Text Available TV content can be enjoyed on multiple screens not only on the TV set. This is what we called Smart or Connected TV, that is to say, an online and interactive television that enables personalized and on demand consumption through a variety of deliveries. The development of connected TV needs new audience measurement systems that allow monitoring the audience across multiple screens. Only a suitable measuring method allows to know the audience for content management and advertising sales.The firstobjective of this paper is to analyze whether the public regional public television in Spain also made this offer. We have chosen the Catalan Corporation of Audiovisual Media (CCMA and EITB, the Basque Radio and Television (EITB. Our second goal is to study the need of new audience measurement systems for this regional television and make suggestions that could help them to exploit the new sources of revenue.

    In 1964, a human humerus was found in a sedimentary deposit in Lezetxiki Cave (Basque Country, northern Iberia). The first studies on the stratigraphy, associated mammal faunal remains and lithic implements placed the deposits containing the humerus into the Riss glacial stage. Direct chronometric evidence has so far been missing, and the previous chronostratigraphic framework and faunal dating gave inconsistent results. Here we report laser ablation U-series analyses on the humerus yielding a minimum age of 164 ± 9 ka, corresponding to MIS 6. This is the only direct dating analysis of the Lezetxiki humerus and confirms a Middle Pleistocene age for this hominin fossil. Morphometric analyses suggest that the Lezetxiki humerus has close affinities to other Middle Pleistocene archaic hominins, such as those from La Sima de los Huesos at Atapuerca. This emphasizes the significance of the Lezetxiki fossil within the populations that predate the Neanderthals in south-western Europe. It is thus an important key fossil for the understanding of human evolution in Europe during the Middle Pleistocene, a time period when a great morphological diversity is observed but whose phylogenetic meaning is not yet fully understood.

    Recent environmental legislation, worldwide, aims to restore and protect the quality of the marine environment. Within this context, in order to maintain the good functioning of marine ecosystems, sediment pollution monitoring is becoming increasingly important. Hence, for this contribution, the spatial distribution of Cd, Fe, Hg, Mn, Ni and Pb accumulation areas were determined, for the sediments of the Basque continental shelf. Statistically-assisted Geographical Information System (GIS)-mapping techniques were used, in order to infer the processes responsible for such accumulations. Differences in contaminant entrance pathways were observed between sectors. However, hydrodynamic conditions favored the rapid dispersal of contaminants and their stable distribution. The methodology used resulted in a suitable approach for identifying contaminant distribution patterns, which could be used in environmental assessment processes. Nevertheless, an important knowledge gap on the distribution of contaminants in offshore sediments was identified. Extensions of actual monitoring programs are suggested, in order to improve the information available for identifying the behavior and process-drivers for contaminants in offshore systems. This would permit the achievement of a more complete approach, to understand the effects of land-derived contaminants, on offshore systems.

    The Ocean Anoxic Event 1 (OAE-1) in central sites of the Basque-Cantabrian Basin exhibits very reducing depositional conditions of sedimentation. These sedimentation events have left a distinct mixture of hydrocarbons that are represented by C22 C30 n-alkanes with a predominance of the even-carbon-number homologues, high relative proportions of squalane and C16 C24 n-alkylcyclopentanes predominated by n-undecyl-, n-tridecyl- and n-pentadecylcyclopentane. Other minor compounds encompass a series of C18 C21 n-alkylcyclohexanes and C18 C24 dimethyl n-alkylcyclohexanes maximized by the even-carbon-number homologues as well as iso- and anteiso-alkanes. This unusual distribution of n-alkanes in this environment provides a new case for comparison with previously reported hypersaline and phosphorite sedimentary deposits where the occurrence of similar n-alkane distributions was reported. In the present case, these major n-alkanes and squalane are indicative of transformation under strong reducing conditions. In contrast, the occurrence of the alkylcyclopentanes, irrespective of the presence of even-carbon-number n-alkanes or squalane, suggests that reductive cyclization of fatty acids is less dependent on strong reducing conditions.

    Highlights: • SOFT 2014 has taken place in Donostia/San Sebastián. • Tungsten/wolfram (W) is a strategic material for the development of fusion. • W was isolated very close to Donostia in the late 18th century as a result of a combination of fortunate circumstances. • This fact is largely unknown even to the fusion materials experts working with W. • We describe this story with some detail. - Abstract: This paper is intended as a preface of the special issue that Fusion Engineering and Design will devote to the best papers presented in the Symposium on Fusion Technology, 2014 (SOFT 2014) that took place in Donostia/San Sebastián. It is a historical note dwelling on the largely unknown story of the isolation of tungsten/wolfram in Spain, more precisely, in the Basque Country, very close to Donostia/San Sebastián, in the late 18th century. Given the current strategic importance of tungsten in the development of fusion as a viable energy source we think it is timely to recall the protagonists and the circumstances involved in the isolation of this metal.

    One aspect of the EPOCA programme (Estudios en el Pirineo Occidental de Contaminacion Acida), the main goal of which is to show the possible effects of an acid rain type pollution on the forest of the Spanish Basque Country, is presented in this paper SO[sub 2] emmissions have been measured as well as the ionic content both of aerosol and in the bulk deposit and in rainwater. The results show that the main ions found in the aerosol are SO[sub 4] [sup 2]- and NH[sub 4]+ (4.5 and 4.1 [mu]g/m[sup 3] respectively). Precipitation is dominated by Cl-, NH[sub 4]+, Ca[sub 2]+ and SO[sub 4][sup 2]- (143.5, 142.8, 102.9 and 61.5 [mu]eq/l). The bulk deposit shows maximum concentrations in SO[sub 4][sup 2]-, Ca[sub 2]+ and NH[sub 4]+ (9.0, 7.2 and 6.0 mg/m[sup 2] day). Losses of Cl- and NH[sub 4]+ have been observed in the bulk deposit and lack of Ca[sub 2]+ in the aerosol due to its presence in the latter in from of large size particles. (author)

    2016-08-01

    Full Text Available Introduction: The objective of this study was to assess a model for improving healthcare integration for patients with multiple chronic diseases in an integrated healthcare organisation in the Basque Country and to propose areas for improvement. Methods: We organised four nominal groups composed of representatives from different categories of clinicians involved in the development of an integrated healthcare organisation and in the integrated care of patients with multiple diseases, namely, internists, general practitioners, and primary care and hospital nurses. Results: The aspect rated most positively was the concept itself of an integrated care model, which is able to improve communication between levels of care, increase the quality of the care provided and enhance patient safety. Additionally, it was agreed that the role of assigned clinicians is a key element. The problems identified mostly concern its implementation in daily practice. Conclusions: The results of this study made it possible to suggest at least 8 areas of improvement to be implemented. These are related to: nurses’ roles; care and monitoring of stable patients; team work; communication with patients; coordination with social workers and between internists and family doctors; as well as the development of an office of medical services to lead the integration process.

    The High Atlas and the Anti Atlas are fold-belts linked to former and still ongoing continent-continent collisions. Despite their high elevation, studies indicate a lack of a deep crustal root (Morocco to analyse teleseismic P- and S-wave receiver functions. Our study yields a crustal thickness ranging from 24 km near the Atlantic coast to 44 km beneath the High Atlas with an average crustal Vp/Vs ratio of 1.77 in the entire region. A crustal thickness of 40 km cannot entirely support the topography in this region. Furthermore, we find the lithosphere-asthenosphere boundary at ˜80 km depth. The lithosphere beneath SW Morocco is thinner than beneath northern Morocco (>150 km). This lithospheric thinning supports the theory of thermal compensation of the mountain ranges. The mantle transition zone thickness amounts to 240 ± 10 km. The transition zone seems to be slightly thinned which might indicate a higher mantle temperature in this region.

    We present the results of allergen content evaluation in 80 dust samples from 31 homes of atopic patients from two climatic areas (humid and subhumid), collected in two seasons of the year (autumn and winter). Monoclonal antibody-based immunoassays were used to quantify Der p 1, Der f 1, Der 2, Lep d 1, and Fel d 1. The results were compared according to climate, season, and the type of sensitization (Pyroglyphidae mites, storage mites, or grass pollens). We underline the predominance of Dermatophagoides pteronyssinus (89% of samples) over D. farinae (16% of samples) in our environment. Der p 1 rates were higher in the humid area (Mann-Whitney P < 0.001), especially in the autumn (Wilcoxon P < 0.05). Lep d 1 was detected in 23% of samples and Lep d 1 levels were higher in the homes of patients sensitized to storage mites (Mann-Whitney P < 0.05), whereas this allergen was not detected in the homes of pollen-allergic patients. Fel d 1 was detected in nine of the 31 homes (16% of samples) although there was a cat in only one home.

  8. Influence of wind turbines on seismic stations in the upper rhine graben, SW Germany

    2017-09-01

    By analysing long- and short-term seismological measurements at wind farms close to the town of Landau, SW Germany, we present new insights into ground motion signals from wind turbines (WTs) at local seismic stations. Because of their need to be located in similar regions with sparsely anthropogenic activities, wind turbines impact seismic stations and their recordings in a way that is not yet fully understood by researchers. To ensure the undisturbed recording tasks of a regional seismic array or a single station by a protected area around those endangered stations, it is very important to investigate the behavior of WTs as a seismic source. For that reason, we calculate averaged one-hour long spectra of the power spectral density (PSD) before and after the installation of a new wind farm within the investigated area. These PSD are ordered according to the rotation speed. We observe a clear increase of the PSD level after the WT installation in a frequency range of 0.5 to 10 Hz up to a distance of 5.5 km away from the WT. By analysing seismic borehole data, we also observe a decrease of the PSD of wind dependent signals with depth. The impact of wind-dependent signals is found to be much more pronounced for the shallower station (150 m depth) than for the deeper one (305 m depth). Using short-term profile measurements, we fit a power-law decay proportional to 1/r b to the main WT-induced PSD peaks and differentiate between near-field and far-field effects of ground motions. For low frequencies in the range from 1 to 4 Hz, we determine a b value of 0.78 to 0.85 for the far field, which is consistent with surface waves. The b value increases (up to 1.59) with increasing frequencies (up to 5.5 Hz), which is obviously due to attenuating effects like scattering or anelasticity. These results give a better understanding of the seismic wavefield interactions between wind turbines (or wind farms) with nearby seismic stations, including borehole installations, in a

    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.

    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.

    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.

    The aim of the present study was to evaluate Fourier transform infrared spectroscopy (FTIR) monitoring of biochemical changes in apoptosis cells. Different concentrations of 5-fluorouracil (5-FU) treated colon cancer cell lines SW620 were used to determine the optimum concentration of 5-FU IC50 by means of MTT assay. Cell starvation and 5-Fu synergistic cell cycle arrest was in G1 and S phase. FTIR combined with flow cytometry was applied to analysis of SW 620 cells and SW620 cells treated with 5-FU for 12h, 24h (early apoptosis) and 48 h (late apoptosis) respectively. The peak position and the intensity of all bands were measured and comparison was made between the SW620 and apoptotic SW620 cells. Apoptosis cells have following characteristics compared with SW620 cells (1) The band at 1 740 cm-1 is an C=O stretching vibration. Changes in these bands can reflect lipid changes, and relative peak intensity ratio 11740/11460 significantly increased (p<0. 05), indicating that the relative contents of lipid in apoptosis cells increased. (2) The band at the 1 410 cm-1 peak represents that C-H stretching related was increased to amino acid residues and shifted to higher wave numbers compared to other groups. I1410o/I 460 at early and late death phase was significantly increased, which suggests that the relative contents of amino acid residues in apoptosis cells increased (p <0. 05). New vibrational bands at 1 120 cm-1 appeared at 24 h and increased at 48 h compared with other groups. The 1 120 cm-1 absorption band is mainly due to ser, serine and threonine C-O(H) stretching vibration, and I1120/I 1460 significantly increased (p<0. 05), indicating that the relative quantity of amino acid residues in apoptosis cells increased due to that DNA unwinds the double helix. (3) 1 240 cm-1 is mainly due to the asymmetric stretching modes of phosphodiester groups shifting to higher wave number, illustrating that nucleic acid conformation was changed in apoptosis cells.

    The eastern end of the Azores-Gibraltar plate boundary is characterized by distributed deformation that accommodates the collision between the Eurasia and Africa plates. Despite this, the active faults in the area can generate very large earthquakes and destructive tsunamis, such as the Great Lisbon Earthquake, that occurred in the 1st November 1755 (estimated Mw = 8.7). The largest instrumental earthquake recorded was the 28th of February 1969 Mw=8.0, localized in the Horseshoe abyssal plain with a thrust fault mechanism. In this study we used a thin-shell approximation (SHELLS- Bird, P., Computers and Geosciences, 25, 383- 394, 1999) to model the neotectonics of this segment of the Africa-Eurasia plate boundary and put constraints on the recurrence periods of earthquakes and tsunamis. In relation to previous neotectonic models in the region we use a better constrained structural map, particularly in the Gulf of Cadiz and SW Iberia, based on recently acquired multi-beam bathymetry, backscatter data and numerous high quality multi- channel seismic profiles. Importantly, the map shows the existence of several NNE-SSW to ENE-WSW thrust faults, associated to prominent bathymetric features, and a set of very long (up to 600 km) strike-slip lineaments, extending between the western Horseshoe Abyssal Plain and the eastern Gulf of Cadiz. Different models have been tested, for various boundary scenarios (geometry and plate velocities) and fault networks, and the results compared with seismic strain release, recent GPS observations and stress orientation. The modeling suggests that, when mature, the long strike-slip lineaments will accommodate most of the relative motion between Eurasia and Africa (aprox. 4 mm/a) along a "transform-type" plate boundary. This situation, however, is associated with only minor thrust faulting in the region and predicts a strong attenuation of the velocity field between the northern Morocco and Gibraltar, in contradiction with present day GPS

    Full Text Available Parallel to the arrival and spread of new trends of thought among the Basque elites in the 18th century, reticent attitudes, sometimes bordering on hostile, developed towards them. The institutionalization of the enlightenment in the Basque country took place with the creation of the «Basque Royal Society for Friends of the country». The analysis of the dominant trends of thought in this Society serves as an observatory of a larger process, to wit the formation of anti-modern thought in the Basque country. this article presents an attempt to analyse this process based on the experiences of the social actors involved, taking into account both the exogenous and the endogenous factors that led to this phenomenon. An attempt is thus made to reconcile the study of its relational networks, the historical context in which they developed and the discourses that emerged from them. The Jesuit element appears repeatedly, although in different forms and registers, as a reference of the products of these discourses.En paralelo a la llegada y difusión de nuevas corrientes de pensamiento entre las élites vascongadas del siglo XVIII, se desarrollaron actitudes reticentes y, en ocasiones, abiertamente hostiles, hacia éstas.

El análisis de las líneas intelectuales dominantes en su seno sirve como observatorio de un proceso de mayores dimensiones, cual es el de la formación del pensamiento antimoderno en el País Vasco. En este artículo se pretende analizar dicho proceso partiendo de las experiencias de los actores sociales que lo protagonizaron, teniendo en cuenta tanto los factores endógenos como los exógenos que dieron lugar a que el fenómeno se produjera. Así, se intenta conciliar el estudio de sus redes relacionales, del contexto histórico en que éstas se desarrollan, y los discursos que de ellas

    To confirm anti-tumor function of mulberry fruit, colon cancer cell line SW620 was treated with different concentrations of mulberry fruit juice. The growth curve was drawn by MTT method to investigate proliferation of SW620 cells. Change of transcriptional level of apoptosis-related gene p53 in SW620 cells and expression level of its encoded protein were detected by fluorescent quantitative PCR and SDS-PAGE to analyze the influencing mechanism of mulberry fruit juice on proliferation and apoptosis of colon cancer cell line SW620. It was found that the inhibitory effect of mulberry fruit juice on the proliferation of SW620 cells was enhanced obviously with the increase of mulberry fruit juice concentration. After being treated with mulberry fruit juice containing 6. 267 3 ×10-3 mg/mL anthocyanin for 24 h, SW620 cells had the following remarkable changes. Cell growth was obviously inhibited. Cells exfoliated and deformed. Cell adherence declined and cell apoptosis was observed. Genomic DNA of SW620 cells showed obvious degradation. The result of fluorescent quantitative PCR showed that expression level of gene p53 in the experimental group increased by 6. 5 folds compared with the control group. In addition, SDS-PAGE assay indicated that the expression level of protein p53 in the experimental group was also obviously higher than that in the control group. These results indicated that mulberry fruit juice has inhibitory effect on proliferation of colon cancer cell line SW620. The inhibitory mechanism may be related to cell apoptosis caused by up-regulation of p53 gene in SW620 cells which was induced by active ingredients of mulberry fruit juice.%为证实桑椹的抗肿瘤功能,以不同浓度桑椹汁处理结肠癌细胞株SW620,应用MTT法对比绘制生长曲线,调查SW620细胞的增殖情况,通过荧光定量PCR、SDS-PAGE检测SW620细胞凋亡相关基因p53的转录及蛋白质表达变化,分析桑椹汁对SW620细胞增殖、凋亡的影响机制.结果显示,桑椹汁对SW

    The Jauru Terrain hosts the Figueira Branca Intrusive Suite (FBS) in the SW of the Amazon Craton (Brazil). The FBS is a series of 1425 Ma layered mafic intrusions, previously interpreted as anorogenic. The FBS area is located in foreland to the Santa Helena orogen, formed by the subduction of the Rio Alegre Terrain under the Jauru Terrain. Potential field methods (magnetic and gravity), gamma-ray spectrometry, geochemical and isotope data were used to characterize and to model the extent of FBS magmatism, the distribution of faults and shear zones in the area, to evaluate affinities of the magmatic activity, and the relation between the FBS and the Santa Helena orogen. The geophysical methods identified three anomalies corresponding with FBS outcrops. A fourth anomaly with significantly higher amplitude was observed to the north of the three anomalies. From south to north, the anomalies were named Indiavaí, Azteca, Figueira Branca and Jauru. These anomalies were modeled and indicated a northwest-southeast trend, parallel to regional shear zones. The gamma-ray data enabled the collection of 50 samples from the FBS rocks, the Alto Jauru group that hosts the FBS, from nearby intrusive suites, and the Rio Alegre Terrain. The 30 freshest samples were analyzed by X-ray fluorescence for oxides and some trace elements, 20 by ICP-MS for Rare-Earth Elements and 10 for Nd-Sr isotope analyses. The FBS samples were gabbros and gabbro-norites with Nb/Yb-Th/Yb and TiO2/Yb-Nb/Yb ratios indicating varying degrees of crustal interaction. The TiO2/Yb-Nb/Yb data suggested a subduction related component and the ɛNd-ɛSr indicated a juvenile source. Samples from coeval adjacent intermediate magma suites displayed similar characteristics, which suggest derivation from a bimodal source probably related with the subduction of the Rio Alegre Terrain. We interpreted the tectonic setting of the FBS as a result of a roll-back of the subducted slab, which resulted in rejuvenation of the

    Evidence for an upper mantle discontinuity located between 60 and 70 km depth have been provided by different seismic data sets acquired in the Southern Iberian peninsula. First indications of such a discontinuity were obtained by the very long offsets seismic refraction shot gathers acquired within the DSS ILIHA project in the early 90's. Clear seismic events recoded by the dense wide-angle seismic reflection shot gathers of the IBERSEIS experiment (2003) provided further constraints on the depth of the discontinuity and first-order estimates of its physical properties beneath the Ossa Morena Zone. Furthermore, the normal incidence Vibroseis deep seismic reflection images of the ALCUDIA transect (2007) extends this structure to the northeast beneath the Central Iberian Zone. This transect images deep laterally discontinuous reflections at upper mantle travel times (19 s) that roughly correspond to depths within the range of 60-70 km. Receiver function studies of the passive seismic recordings acquired by the IBERARRAY (TOPOIBERIA projects) provides additional support for the existence of this upper mantle structure and suggests that this is a relatively large scale regional feature. Two major scenarios need to be addressed when discussing the origin and nature of this deep structure. One is the tectonic scenario in which the structure maybe be related to a major tectonic event such as an old subduction process and therefore represent an ancient slab. A second hypothesis, would relate this feature to a phase change in the mantle. This latter assumption requires this feature ought to be a broader scale boundary which could be identified by different seismic techniques. Reflectivity modeling carried out over the IBERSEIS wide angle reflection data concludes that the observed phase is consistent with an heterogeneous gradient zone located at, approximately, 61-72 km depth. A layered structure with alternating velocities within ranges 8.1 to 8.3 km/s is necessary in

    Peach (Prunus persica, Rosaceae) is an extremely popular tree fruit worldwide, with an annual production near 20 million tons. Peach is widely thought to have origins in China, but its evolutionary history is largely unknown. The oldest evidence for the peach has been Chinese archaeological records dating to 8000-7000 BP. Here, we report eight fossil peach endocarps from late Pliocene strata of Kunming City, Yunnan, southwestern China. The fossils are identical to modern peach endocarps, including size comparable to smaller modern varieties, a single seed, a deep dorsal groove, and presence of deep pits and furrows. These fossils show that China has been a critical region for peach evolution since long before human presence, much less agriculture. Peaches evolved their modern morphology under natural selection, presumably involving large, frugivorous mammals such as primates. Much later, peach size and variety increased through domestication and breeding.

    We performed a rough estimate of the non-perturbative value of the clover term coefficient cSW for the APE stout link Wilson fermion. We varied the number of smearings from Nsmear=1 to 6 and adopted beta values roughly corresponding to the lattice spacing of 0.1 fm. We used the Schroedinger functional technique for an evaluation of cSW and found that cSW decreases monotonically as we increase Nsmear but has a 10% order of deviation from the tree level value for Nsmear=6.

This work is intended to support the idea that the gender, educational and political ideology of the Basque nationalist women in the pre-war thirties, among whom Julene Azpeitia was a significant exponent, must be understood within the bourgeois ideology of European nation-states —and the contradictions that happened in a stateless nation. In order to demonstrate so we have analysed her journalistic and pedagogical writings, and approached them as a case study. This study has been completed with some videotaped in-depth interviews to significant nationalist women from the Republican period.El acercamiento biográfico realizado por J. J. de la Granja y G.

    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)

    For the first time, three coumarins were isolated from the hexane extract of limes (Citrus aurantifolia) and purified by flash chromatography. The structures were identified by NMR (1D, 2D) and mass spectral analyses as 5-geranyloxy-7-methoxycoumarin, limettin, and isopimpinellin. These compounds inhibited human colon cancer (SW-480) cell proliferation, with 5-geranyloxy-7-methoxycoumarin showing the highest inhibition activity (67 %) at 25 µM. Suppression of SW480 cell proliferation by 5-geranyloxy-7-methoxycoumarin was associated with induction of apoptosis, as evidenced by annexin V staining and DNA fragmentation. In addition, 5-geranyloxy-7-methoxycoumarin arrested cells at the G0/G1 phase, and induction of apoptosis was demonstrated through the activation of tumour suppressor gene p53, caspase8/3, regulation of Bcl2, and inhibition of p38 MAPK phosphorylation. These findings suggest that 5-geranyloxy-7-methoxycoumarin has potential as a cancer preventive agent. Georg Thieme Verlag KG Stuttgart · New York.

    AIM: TRAIL (tumor necrosis factor-related apoptosisinducing ligand) has been reported to specifically induce apoptosis of cancer cells although only a small percentage of cell lines were sensitive to it. Cell lines not responding to TRAIL in vitro were said to be more prone to apoptosis when TRAIL was combined with another anticancer agent.Generally, factors affecting drug-sensitivity involve many apoptosis-related proteins, including p53. The expression of wild-type p53 gene was proposed as an important premise for tumor cells responding to chemotherapy. The present study was to investigate the cell killing action of TRAIL on colon cancer cell line SW480, its synergistic effect with doxorubicin, and the possible mechanisms. METHODS: SW480 cells were cultured in the regular condition and incubated with different levels of agents.Morphologic changes in these cells after treatment were observed under phase-contrast microscope and cytotoxicity by TRAIL alone and in combination with doxorubicin was quantified by a 1-day microculture tetrazolium dye (MTT)assay. In addition, flow cytometry assay (FCM) and transmission electron microscopy were used to detectapoptosis among these cells. Variation of p53 protein level among different groups according to concentrations of agents was measured by Western blot assay.RESULTS: (1) SW480 cells were not sensitive to TRAIL,with IC50>1 mg@L1 and dose-independent cytotoxicity. (2)SW480 cells were sensitive to doxorubicin at a certain degree,with dose-dependent cytotoxicity and IC50=65.25+3.48μmol@L-1. (3) TRAIL could synergize with doxorubicin to kill SW480 cells effectively, which was represented by the boosted killing effect of doxorubicin on theses cells. IC50 of doxorubicin against SW480 cells sharply reduced when it was combined with TRAIL. (4) Subtoxic TRAIL (100 μg.L-1),combined with subtoxic doxorubicin (0.86 μmol@L1), could kill SW480 cells sufficiently. Cytotoxicity by MTT assay arrived at 80.12+2.67%, which was

    We conducted a spectroscopic and photometric study of SDSS J075653.11+085831. X-ray observations were also attempted. We determined the orbital period of this binary system to be 3.29 hours. It is a deep eclipsing system, whose spectra shows mostly single peaked Balmer emission lines and a quite 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 these features point towards affiliation of this object to the growing number of SW Sex-type objects. We developed a phenomenological model of a SW Sex system to reproduce the observed photometric and spectral features.

  19. Seismic hazard impact of the Lower Tagus Valley Fault Zone (SW Iberia)

    Science.gov (United States)

    Vilanova, Susana P.; Fonseca, Joao F. B. D.

    The seismic hazard of SW Iberia is composed of two contributions: offshore, large to very large events on the plate boundary between Africa and Eurasia such as the Lisbon earthquake of 1755 or the Gorringe Bank earthquake of 1969; and onshore, moderate to strong intraplate earthquakes on inherited crustal fractures. One of these zones of crustal weakness is the Lower Tagus Valley (LTV) fault zone, which displays the highest level of seismic hazard in Western Iberia. In this paper we review the active tectonics and seismicity of the LTV, integrating previous geophysical data with recent results of paleoseismological investigations, and discuss its impact on the seismic hazard of SW Iberia. We conclude that the seismic zonation for hazard assessment currently in force in the building code is biased towards the scenario of distant offshore rupture, and does not take adequately into account the LTV seismic source.

    We propose a semi-automatic HW/SW codesign flow for low-power and low-cost Neuro-Fuzzy embedded systems. Applications range from fast prototyping of embedded systems to high-speed simulation of Simulink models and rapid design of Neuro-Fuzzy devices. The proposed codesign flow works with different technologies and architectures (namely, software, digital and analog). We have used The Mathworks' Simulink environment for functional specification and for analysis of performance criteria such as timing (latency and throughput), power dissipation, size and cost. The proposed flow can exploit trade-offs between SW and HW as well as between digital and analog implementations, and it can generate, respectively, the C, VHDL and SKILL codes of the selected architectures.

    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.

    The COxSwAIN project focuses on building an image and video compression scheme that can be implemented in a small or low-power satellite. To do this, we used Compressive Sensing, where the compression is performed by matrix multiplications on the satellite and reconstructed on the ground. Our paper explains our methodology and demonstrates the results of the scheme, being able to achieve high quality image compression that is robust to noise and corruption.

    With new THz maps that cover an area of ~3.3x2.1 pc^2 we probe the spatial distribution and association of the ionized, neutral and molecular gas components in the M17 SW nebula. We used the dual band receiver GREAT on board the SOFIA airborne telescope to obtain a 5'.7x3'.7 map of the 12CO J=13-12 transition and the [C II] 158 um fine-structure line in M17 SW and compare the spectroscopically resolved maps with corresponding ground-based data for low- and mid-J CO and [C I] emission. For the first time SOFIA/GREAT allow us to compare velocity-resolved [C II] emission maps with molecular tracers. We see a large part of the [C II] emission, both spatially and in velocity, that is completely non-associated with the other tracers of photon-dominated regions (PDR). Only particular narrow channel maps of the velocity-resolved [C II] spectra show a correlation between the different gas components, which is not seen at all in the integrated intensity maps. These show different morphology in all lines but give hardly...

    2012-01-01

    Full Text Available This study reports age and geochemical analyses of basaltic rocks dredged from volcanic seamounts offshore SW Taiwan. 40Ar/39Ar dating results of these rocks show them to be of the early Miocene age of ~22 - 21 Ma. They are evolved alkali basalts that show OIB-type geochemical features similar to post-spreading seamount basalts (14 - 3.5 Ma in the South China Sea (SCS and Miocene intraplate basalts on the Penghu Islands (16 - 8 Ma and NW Taiwan (23 - 9 Ma. Their Sr-Nd-Pb isotope data plot within the range of the SCS seamount basalts that show an EM2-like component in the mantle source. The age and overall geochemical characteristics of the dredged basalts are comparable to those of the Kungkuan basalts, NW Taiwan and Baolai basalts, SW Taiwan, suggesting an extensive alkali basaltic volcanism along the southeastern Eurasian continental margin during the early Miocene that resulted from regional lithospheric extension in association with seafloor spreading in the South China Sea.

  8. Computer Simulation of Single-Well Steam Assisted Gravity Drainage (SW-SAGD), SUPRI TR-119

    Energy Technology Data Exchange (ETDEWEB)

    Elliott, Keith T.; Kovscek, Anthony R.

    1999-08-09

    Steam assisted gravity drainage (SAGD) is an effective method of producing heavy oil and bitumen. In a typical SAGD approach, steam is injected into a horizontal well located directly above a horizontal producer. A steam chamber grows around the injection well and helps displace heated oil toward the production well. Single-well (SW) SAGD attempts to create a similar process using only one horizontal well. This may include steam injection from the toe of the horizontal well with production at the heel. Obvious advantages of SW-SAGD include cost savings and utility in relatively thin reservoirs. However, the process is technically challenging. To improve early-time response of SW-SAGD, it is necessary to heat the near-wellbore area to reduce oil viscosity and allow gravity drainage to take place. Ideally heating should occur with minimal circulation or bypassing of stream. Since project economics are sensitive to early production response, we are interested in optimizing the start -up procedure.

    Full Text Available Hardware/software (HW/SW cosimulation integrates software simulation and hardware simulation simultaneously. Usually, HW/SW co-simulation platform is used to ease debugging and verification for very large-scale integration (VLSI design. To accelerate the computation of the gesture recognition technique, an HW/SW implementation using field programmable gate array (FPGA technology is presented in this paper. The major contributions of this work are: (1 a novel design of memory controller in the Verilog Hardware Description Language (Verilog HDL to reduce memory consumption and load on the processor. (2 The testing part of the neural network algorithm is being hardwired to improve the speed and performance. The American Sign Language gesture recognition is chosen to verify the performance of the approach. Several experiments were carried out on four databases of the gestures (alphabet signs A to Z. (3 The major benefit of this design is that it takes only few milliseconds to recognize the hand gesture which makes it computationally more efficient.

    Full Text Available Abstract Background Sigma-2 receptors are over-expressed in proliferating cancer cells, making an attractive target for the targeted treatment of pancreatic cancer. In this study, we investigated the role of the novel sigma-2 receptor ligand SW43 to induce apoptosis and augment standard chemotherapy. Results The binding affinity for sigma-2 ligands is high in pancreas cancer, and they induce apoptosis with a rank order of SV119 in vitro. Combining these compounds with gemcitabine further increased apoptosis and decreased viability. Our in vivo model showed that sigma-2 ligand treatment decreased tumor volume to the same extent as gemcitabine. However, SW43 combination treatment with gemcitabine was superior to the other compounds and resulted in stabilization of tumor volume during treatment, with minimal toxicities. Conclusions This study shows that the sigma-2 ligand SW43 has the greatest capacity to augment gemcitabine in a pre-clinical model of pancreas cancer and has provided us with the rationale to move this compound forward with clinical investigations for patients with pancreatic cancer.

    Available Usbnd Pb age data for the Cornubian Batholith of SW England is based almost entirely on monazite and xenotime, and very little zircon Usbnd Pb age data has been published. As a result, no zircon inheritance data is available for the batholith, by which the nature of the unexposed basement of the Rhenohercynian Zone in SW England might be constrained. Zircon LA-ICPMS data for the Cornubian Batholith provides Concordia ages (Bodmin Moor granite: 316 ± 4 Ma, Carnmenellis granite: 313 ± 3 Ma, Dartmoor granite: ~ 310 Ma, St. Austell granite: 305 ± 5 Ma, and Land's End granite: 300 ± 5 Ma) that are consistently 20-30 Ma older than previously published emplacement ages for the batholith and unrealistic in terms of geologic relative age relationships with respect to the country rock. This discrepancy is likely as a consequence of minor pre-granitic Pb inheritance. Several of the batholith's granite plutons contain a component of late-Devonian inheritance that may record rift-related, lower crustal melting or arc-related magmatism associated with subduction of the Rheic Ocean. In addition, the older granites likely contain Mesoproterozoic inheritance, although the highly discordant nature of the Mesoproterozoic ages precludes their use in assigning an affinity to the Rhenohercynian basement in SW England.

    Jing-Shu Zhang

    Full Text Available Colorectal cancer is one of the most serious illnesses among diagnosed cancer. As a new type of anti-cancer composition from tocotrienol-rich fraction of palm oil, γ-tocotrienol is widely used in anti-cancer research. The objectives of this study were to investigate the effects of γ-tocotrienol on human colon cancer SW620 and HCT-8 cells. We showed that treatment with different concentrations of γ-tocotrienol resulted in a dose dependent inhibition of cell growth. Cell death induced by γ-tocotrienol was mediated by a paraptosis-like cell death in SW620 and HCT-8 cells. Real-time RT-PCR and western blot analyses showed that γ-tocotrienol inhibited the expression level of β-catenin, cyclin D1 and c-jun. These data suggest that a paraptosis-like cell death induced by γ-tocotrienol in SW620 cells is associated with the suppression of the Wnt signaling pathway, which offers a novel tool for treating apoptosis-resistance colon cancer.

    Oxymatrine (OMT) is a type of alkaloid extracted from a traditional Chinese medicinal herb, Sophora flavescens. Although the antitumor activities of OMT have been observed in various cancers, there are no reports regarding the effects of OMT on human synovial sarcoma. In the present study, we analyzed the antitumor activities of OMT in SW982 human synovial sarcoma cells and determine whether high mobility group box protein 1 (HMGB1)-mediated autophagy was associated with its therapeutic effects. We found that OMT exhibited antitumor activity in SW982 cells and facilitated increases in autophagy. Inhibition of autophagy by 3-MA or ATG7 siRNA increased the level of apoptosis, which indicated that OMT-induced autophagy protected cells from the cytotoxicity of OMT. Administration of OMT to SW982 cells increased the expression of HMGB1. When HMGB1 was inhibited via HMGB1-siRNA, OMT-induced autophagy was decreased, and apoptosis was increased. Furthermore, we found that HMGB1-siRNA significantly increased the expression of p-Akt and p-mTOR. OMT-induced autophagy may be mediated by the Akt/mTOR pathway, and HMGB1 plays a vital role in the regulation of autophagy. Therefore, we believe that combining OMT with an inhibitor of autophagy or HMGB1 may make OMT more effective in the treatment of human synovial sarcoma.

    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.

    Coherent ecological networks (EN) composed of core areas linked by ecological corridors are being developed worldwide with the goal of promoting landscape connectivity and biodiversity conservation. However, empirical assessment of the performance of EN designs is critical to evaluate the utility of these networks to mitigate effects of habitat loss and fragmentation. Landscape genetics provides a particularly valuable framework to address the question of functional connectivity by providing a direct means to investigate the effects of landscape structure on gene flow. The goals of this study are (1) to evaluate the landscape features that drive gene flow of an EN target species (European pine marten), and (2) evaluate the optimality of a regional EN design in providing connectivity for this species within the Basque Country (North Spain). Using partial Mantel tests in a reciprocal causal modeling framework we competed 59 alternative models, including isolation by distance and the regional EN. Our analysis indicated that the regional EN was among the most supported resistance models for the pine marten, but was not the best supported model. Gene flow of pine marten in northern Spain is facilitated by natural vegetation, and is resisted by anthropogenic landcover types and roads. Our results suggest that the regional EN design being implemented in the Basque Country will effectively facilitate gene flow of forest dwelling species at regional scale.

    2015-12-01

    Full Text Available Silicic, mafic and alkali intra-seam tonsteins have been known from SW China for a number of years. This paper reports on the geochemical compositions of coals and tonsteins from three seam sections of the Songzao Coalfield, SW China, and evaluates the geological factors responsible for the chemical characteristics of the coal seams, with emphasis on the influence from different types of volcanic ashes. The roof and floor samples of the Songzao coal seams mostly have high TiO2 contents, consistent with a high TiO2 content in the detrital sediment input from the source region, namely mafic basalts from the Kangdian Upland on the western margin of the coal basin. The coals from the Songzao Coalfield generally have high ash yields and are highly enriched in trace elements including Nb, Ta, Zr, Hf, rare earth elements (REE, Y, Hg and Se; some variation occurs among different seam sections due to input of geochemically different volcanic ash materials. The geochemistry of the Songzao coals has also been affected by the adjacent tonstein/K-bentonite bands. The relatively immobile elements that are enriched in the altered volcanic ashes also tend to be enriched in the adjacent coal plies, possibly due to leaching by groundwaters. The coals near the alkali tonstein bands in the Tonghua and Yuyang sections of the Songzao Coalfield are mostly high in Nb, Ta, Zr, Hf, Th, U, REE and Y. Coal samples overlying the mafic K-bentonite in the Tonghua section are high in V, Cr, Zn and Cu. The Datong coal, which has neither visible tonstein layers nor obvious volcanogenic minerals, has high TiO2, V, Cr, Ni, Cu and Zn concentrations in the intervals between the coal plies affected by mafic and alkaline volcanic ashes. This is consistent with the suggestion that a common source material was supplied to the coal basin, derived from the erosion of mafic basaltic rocks of the Kangdian Upland. Although the Songzao coal is generally a high-sulfur coal, most of the

    Recognition of the main morphostructural features of the western edge of the Huila Plateau (SW Angola) can be done by using remote sensing techniques associated with field work. A digital elevation model (DEM) of the area was built for this purpose. This model is based on altimeter data acquired from the Aster sensor, on which image processing techniques such as enhancement techniques, contrast change and filtering were applied. Other techniques, such as RGB colour composition, were also tested. The processed satellite images were interpreted by visual process and the results were then compared with available geological maps (scale 1: 1 000 000). To facilitate both analysis and interpretation, the edge of the plateau was divided into three sectors: northern (or Chongoroi Edge), central (or Humpata Edge) and southern (or Oncocua Edge). For each sector, the main morphological aspects and main lineament systems were identified and characterized. In the specific case of the central sector, these parameters were also confirmed by field work. This study shows that the morphology of the western edge of the plateau is dominated by N50°W-N60°W, N60°E and N-S trending main tectonic systems. These results have important implications in terms of geological mapping and regional tectonics as well as in land-use planning and other areas, such as hydrogeology or geotechnics.

    Calculation of (A/sub x/B/sub y/) (x=1, 13; y=6, 14) clusters, corresponding to ideal crystals of alkaline earth metal oxides (AEMO) MgO, CaO, SrO by means of molecular cluster (MC) and crystal cluster (CC) SCF-X/sub /-SW method is carried out. MC method is not suitable for description of ideal AEMO electron structure due to long-range Coulomb interaction and potential cluster effect. Even in CC method at x < 13 and y < 14 (A/sub x/B/sub y/) cluster nonstoichiometry is inhibitory to the obtaining of satisfactory agreement with the experimental optical and X-ray spectra. (A13B14) and (B13A14) clusters satisfactorily reproduce partial composition of valence band (VB) and conduction band (CB), VB and CB widths, a fine structure of oxygen K-emission spectra in MgO and also experimental distribution of electron density. Sphere radii variation effect on the value of intersphere region error with muffin-tin averaging is considered.

    Mesquite [Prosopis juliflora (SW) D.C.], a perennial tropical plant commonly found in Brazilian semi-arid region, is a viable raw material for fermentative processes because of its low cost and production of pods with high content of hydrolyzable sugars which generate many compounds, including ethanol. This study aimed to evaluate the use of mesquite pods as substrate for ethanol production by Z. mobilis UFPEDA- 205 in a submerged fermentation. The fermentation was assessed for rate of substrate yield to ethanol, rate of ethanol production and efficiency of fermentation. The very close theoretical (170 g L{sup -1}) and experimental (165 g L{sup -1}) maximum ethanol yields were achieved at 36 h of fermentation. The highest counts of Z. mobilis UFEPEDA-205 (both close to 6 Log cfu mL{sup -1}) were also noted at 36 h. Highest rates of substrate yield to ethanol (0.44 g ethanol g glucose{sup -1}), of ethanol production (4.69 g L{sup -1} h{sup -1}) and of efficiency of fermentation (86.81%) were found after 30 h. These findings suggest mesquite pods as an interesting substrate for ethanol production using submerged fermentation by Z. mobilis. (author)

    The Pleistocene carbon isotope record from the core MD 97-2114 (SW Pacific Ocean) is used to reconstruct the surface- and deep-water circulation variability during the last one million years. The analyzed core has been recovered from an IMAGES (International Marine Past Global Change Study) cruise, at 1,935 m water depth, on the north eastern slope of Chatham Rise (east of New Zealand). This region represents a key area for investigating the evolution during the Pleistocene of the biogeochemistry and dynamic of the southern oceanic fronts (Subtropical, Subantarctic, Polar Fronts). In fact, in this crucial area the largely wind-driven Antarctic Circumpolar Current (ACC) interacts with the west Pacific Ocean circulation via Deep Western Boundary Current (DWBC) coming from the Antarctic region. The excellent record of the core MD 97-2114 offers a unique opportunity to investigate the climate and oceanographic evolution of the region at a millenarian time-scale by mean of a high-resolution chemostratigraphic, multi-proxy dataset. Moreover, quantitative data on the calcareous planktic and benthic microfossil record, integrated with the C and O isotope data performed both on planktic and benthic foraminiferal tests, allows to understand coupling or decoupling events between sea surface and bottom waters in terms of productivity, current activity and carbon export dynamics. The northward migration of the Polar Front during the Mid-Pleistocene Transition is particularly focalized for its potential effects on the primary productivity and on the carbon biological pump. This oceanographic event seems to be related to a variation in the volume of the DWBC like a response to changes in the water production from the Antarctic source, as already proposed in previous papers.

    ${\\it Swift}$ J2058.4+0516 (Sw J2058+05, hereafter) has been suggested as the second member (after Sw J1644+57) of the rare class of tidal disruption events accompanied by relativistic ejecta. Here we report a multiwavelength (X-ray, ultraviolet/optical/infrared, radio) analysis of Sw J2058+05 from 3 months to 3 yr post-discovery in order to study its properties and compare its behavior with that of Sw J1644+57. Our main results are as follows. (1) The long-term X-ray light curve of Sw J2058+05 shows a remarkably similar trend to that of Sw J1644+57. After a prolonged power-law decay, the X-ray flux drops off rapidly by a factor of $\\gtrsim 160$ within a span of $\\Delta$$t$/$t$ $\\le$ 0.95. Associating this sudden decline with the transition from super-Eddington to sub-Eddington accretion, we estimate the black hole mass to be in the range of $10^{4-6}$ M$_{\\odot}$. (2) We detect rapid ($\\lesssim 500$ s) X-ray variability before the dropoff, suggesting that, even at late times, the X-rays originate from close ...

    Virosecurinine, the major alkaloid isolated from Securinega suffruticosa Pall Rehd was found to exhibit growth inhibition and cytotoxicity against huaman colon cancer SW480 cells via the microculture tetrazolium (MTT) assay. Due to its greater cytotoxic potency and selectivity towards SW480 cells, flow cytometry was used to analyze the cell cycle distribution of control and treated SW480 cells whereas Annexin V-FITC/PI flow cytometry analysis was carried out to confirm apoptosis induced by virosecurinine in SW480 cells. Apoptotic regulatory genes were determined by RT-PCR analysis. Virosecurinine was found to induce G1/S cell cycle arrest which led to predominantly apoptotic mode of cell death. Mechanistically, virosecurinine was found to up-regulated the Bax gene expression and down-regulated the Bcl-2 expression in SW480, The ratio of Bcl-2 to Bax was significantly decreased. Hence, we suggest that virosecurinine induced apoptosis in SW480 cells by affecting the expression of bcl-2 and bax.

    In places where drought is one of the main climatic constraints, land degradation and desertification can take place if soils have suffered from a loss of biological production and resilience caused by both, natural and anthropogenic factors. It is important to identify such sensitive areas and to describe the driving forces leading to land degradation in order to properly understand the phenomenon. The main goal of this work is to identify places with different sensitivity to land degradation in Extremadura (Spain) by means of a modeling approach developed in the European Commission funded MEDALUS project (Mediterranean Desertification Land Use) (Kosmas et al., 1999), which identifies such areas on the basis of an index (ESA index, Environmental Sensitive Area index) in which environmental quality (climate, vegetation, soil) as well as anthropogenic factors (management) are included. A geographical information system approach was applied in this study. Sensitivity to degradation is analyzed by combining four quality indexes (soil, climate, vegetation and management). The first three giving information about environmental conditions and the later about man-related factors. Each of those quality indexes result from averaging several parameters involved in their calculation. The study area covered the whole region of the Extremadura (41.633 km²), located in the SW Iberian Peninsula. For the classification of soil cover classes, the CORINE land cover 2000 maps were used and reclassified according to the requirements. Some information was also gathered from the National Forest Inventory. A digital elevation model of 25 m pixel size was used to calculate terrain slope and aspect and the climate data were obtained from the Digital Climatic Atlas of the Iberian Peninsula. Two maps of environmental sensitivity to land degradation with different legend resolution (4 and 8 classes) were established and tested by comparing the results obtained (classes of sensitivity) with

    Full Text Available In an effort to quantify the time parameter in the tectonomagmatic evolution of what has been called the Southern Svecofennian Arc Complex (SSAC of SW Finland, advanced radiometric dating techniques have here been applied to rock groups of key importance in that area. In this paper we report the results of 131 high-resolution ionmicroprobe spot analyses (SIMS of zircons, and 33 measurements using isotope dilution mass spectrometry (ID-TIMS on zircon, monazite and titanite, and employing both large-sample multi-grain as well as single-grain techniques. The Torsholma area of the Åland archipelago, situated between southern Finland and central Sweden, is a key structural area significant to resolve the time dimension in Svecofennian tectonics. There a collage of imbricated rock slabs was formed by tectonic shortening representing the culmination of large-scale penetrative Svecofennian deformation. Another structurally significant feature investigated is the South FinlandShear Zone (SFSZ that transects the southwest-Finnish archipelago and further east follows the southern coast of Finland. This shear zone forms the southern limit of the c. 1830 Ma Late Svecofennian Granite and Migmatite Zone (LSGM and also features deformations of a later stage when the considered region of Svecofennian crust was consolidated. The obtained age results and their tectonic analysis can be summarized as follows. The Enklinge volcanic sequence (1885±6 Ma is within error limits coeval with the intrusion of abundant early-kinematic gneissose granodiorites whose average age of 1884±5 Ma marks the formation of new crust in this region. Some of these geisses contain a significant amount of 2000–2080 Ma zircon. Although many Svecofennian granitoids are known to contain heterogeneous zircon populations, mainly formed c. 1890 Ma ago but also containing an inherited component, the Kökar gneiss is, to the best of our knowledge, the first case where inheritance from c. 2030

    Deep-water diatremes and related eruption products are rare and they have been mainly interpreted from seismic-based data. We present lithofacies and geochemistry analysis of two Lower Cretaceous (Albian) deep-water diatremes and associated extra-diatreme volcaniclastic deposits at a well-exposed outcrop of the northern margin of the Basque-Cantabrian Basin (north Iberia). The studied diatremes are located along a N-S trending Albian fault and present sub-circular to elongate sections, inward-dipping steep walls and smooth to very irregular contacts with the host rocks. They are filled by un-bedded mixed breccias constituted by juvenile and lithic (sedimentary, igneous and metamorphic) clasts. Their textural and structural characteristics indicate that they represent lower diatreme and root zones of the volcanic system. Mapping, geochemical and petrologic data from diatreme-fills support their genetic relationship with the extra-diatreme volcaniclastic beds, which would be generated by the eruption of an incipiently vesicular trachytic magma. Studied diatremes result from multiple explosions that lasted over an estimated period of 65 k.y. during the Late Albian (H. varicosum ammonite Zone, pro parte), and reached up to a maximum subsurface depth of ca. 370 m, whereas extra-diatreme volcaniclastic beds were formed by eruption-fed gravity-driven flows on the deep-water (200-500 m) paleoseabed. Petrological features suggest that these diatremes and related extra-diatreme deposits resulted mainly from phreatomagmatic explosions. In addition, organic geochemistry data indicate that the thermal effect of the trachytic melts on the sedimentary host caused the conversion of the abundant organic matter to methane and CO2 gases, which could also contribute significantly to the overpressure necessary for the explosive fragmentation of the magma and the host rocks. Considering the inferred confining pressures (ca. 8-11 MPa) and the possible participation of unvesiculated (or

    A study of the Liassic sequence in the Basque-Cantabrian Basin has shown the presence of organic-rich (TOC, HI and S{sub 2} up to 8.7%, 760 and 56.5 mg/g, respectively) Pliensbachian-early Toarcian black shales that constitute the only feasible source rock for Ayoluengo oil. The stratigraphical and sedimentological data show that these black shales developed into a major transgressive sequence of hemipelagic Lotharingian-Toarcian facies, which suggests the presence of anoxic or near anoxic bottom water conditions in troughs during their deposition. The {delta}{sup 13}C composition, and a detailed study of the linear, branched, isoprenoid, steroid and hopanoid aliphatic hydrocarbons in these shales, marls and the Ayoluengo oil confirms this hypothesis. Specifically, the {delta}{sup 13}C values of the total solvent extract of the thicker shale (No. 2) and the oil are -29.93 and -29.88``per mille``, respectively; also a close similarity in the relative compositions of steranes and hopanes is observed between these samples. The distributions of these compounds exhibit several distinct features. The steranes in this shale and crude oil are characterized by a depletion of C{sub 28} vs C{sub 27} and C{sub 29} homologues (24 vs 32 and 44%, respectively), which is consistent with the carbon number sterane distributions generally observed among Upper Paleozoic to Liassic rock-sourced oils. Furthermore, hopanes and steranes are characterized by their high relative content of rearranged molecules. Diasteranes (13{beta}(H),17{alpha}(H)- and 13{alpha}(H),17{beta}(H)- series) are the dominant compounds among the steranes and significant amounts of 18{alpha}(H)-17{alpha}methyl-28-norhopanes (C{sub 27}, C{sub 29} and C{sub 30} homologues) and 17{alpha}(H)-15{alpha}-methyl- 27 norhopanes (C{sub 30} homologue) are found in the hopanoid hydrocarbons. Conversely, the proportion of these rearranged molecules in other sediment samples from the same formation decrease with increasing

    In this study, multi-drug resistant Escherichia coli Sw1 (E. coli Sw1) and active lytic phage EcSw was isolated from feces samples of Sus scrofa domesticus (piglet) suffering from diarrhea. Transmission electron microscopy (TEM) indicated that isolated EcSw belongs to the Myoviridae family with an icosahedral head (80 ± 4) and a long tail (180 ± 5 nm). The EcSw phage genome size was estimated to be approximately 75 Kb of double-stranded DNA (dsDNA). Phage dynamic studies show that the latent period and burst size of EcSw were approximately 20 min and 28 PFU per cell, respectively. Interestingly, the EcSw phage can tolerate a wide range of environmental conditions, such as temperature, pH and ions (Ca(2+) and Mg(2+)). Furthermore, genome sequence analysis revealed that the lytic genes of the EcSw phage are notably similar to those of enterobacteria phages. In addition, phage-antibiotic synergy has notable effects compared with the effects of phages or antibiotics alone. Inhibition of E. coli Sw1 and 0157:H7 strains showed that the limitations of host specificity and infectivity of EcSw. Even though, it has considerable potential for phage therapy for handling the problem of the emergence of multidrug resistant pathogens.

    2011-04-01

    Our current understanding of the tectonic history of the principal Pan-African orogenic belts in southwestern Africa, reaching from the West Congo Belt in the north to the Lufilian/Zambezi, Kaoko, Damara, Gariep and finally the Saldania Belt in the south, is briefly summarized. On that basis, possible links with tectono-stratigraphic units and major structures on the eastern side of the Río de la Plata Craton are suggested, and a revised geodynamic model for the amalgamation of SW-Gondwana is proposed. The Río de la Plata and Kalahari Cratons are considered to have become juxtaposed already by the end of the Mesoproterozoic. Early Neoproterozoic rifting led to the fragmentation of the northwestern (in today's coordinates) Kalahari Craton and the splitting off of several small cratonic blocks. The largest of these ex-Kalahari cratonic fragments is probably the Angola Block. Smaller fragments include the Luis Alves and Curitiba microplates in eastern Brazil, several basement inliers within the Damara Belt, and an elongate fragment off the western margin, named Arachania. The main suture between the Kalahari and the Congo-São Francisco Cratons is suspected to be hidden beneath younger cover between the West Congo Belt and the Lufilian/Zambezi Belts and probably continues westwards via the Cabo Frío Terrane into the Goiás magmatic arc along the Brasilia Belt. Many of the rift grabens that separated the various former Kalahari cratonic fragments did not evolve into oceanic basins, such as the Northern Nosib Rift in the Damara Belt and the Gariep rift basin. Following latest Cryogenian/early Ediacaran closure of the Brazilides Ocean between the Río de la Plata Craton and the westernmost fragment of the Kalahari Craton, the latter, Arachania, became the locus of a more than 1,000-km-long continental magmatic arc, the Cuchilla Dionisio-Pelotas Arc. A correspondingly long back-arc basin (Marmora Basin) on the eastern flank of that arc is recognized, remnants of which

    The Lake District, located in the SW Anatolia region of Turkey, hosts a number of lakes with unique water chemistry. Among them, Lake Acigol, Lake Salda and Lake Yarisli display extreme biogeochemical conditions. In terms of their water chemistry and diverse prokaryotic community, each lake sets a great example for microbially mediated reactions (e.g carbonate precipitation). Lake Acigol (average pH around 8.6) is known for hypersaline and alkaline water chemistry. Lake Salda (average pH around 9.1) is known for its hydromagnesite beaches, clayey-hydromagnesite shoreline and ancient-modern stromatolite formations as well as being a model for Mars. For the first time, Lake Yarisli having alkaline conditions with an average pH value of 9.5 is investigated for its geochemistry and geobiology during this study. Algal bloom and well developed cyanobacterial mats are visible on shallow waters along the Eastern shoreline of the lake. In scope of elucidating complex bio/geochemical reactions that regulate C, S and O cycles in the extreme conditions of these lakes, water, surface sediment and shallow core samples were collected. For the first time, prokaryotic diversity of Lake Acigol, Salda and Yarisli were determined by Next-Generation Sequencing (NGS) during this study (Balci et al., 2013). Preliminary results revealed the total number of bacterial classes determined for Lake Acigol, Lake Salda and Lake Yarisli as 22, 19 and 19; respectively. Lake Acigol, Salda and Yarisli are mostly dominated by bacterial classes of Alphaproteobacteria (68.2%, 25.6% and 1.9%; respectively), Cyanobacteria (10.2%, 5.3% and 92.9%; respectively), Bacilli (9.6%, 23.7% and 0.45%; respectively), Gammaproteobacteria (6.1%, 39.6% and 4.3%; respectively) and Actinobacteria (2.7%, 1.8% and 0.06%; respectively). The total number of archaeal classes determined for Lake Acigol, Lake Salda and Lake Yarisli are 8, 7 and 6; respectively. Common most dominant archaeal classes of Lake Acigol, Lake Salda

    Full Text Available BACKGROUND: Fomitopsis pinicola (Sw. Ex Fr.m Karst (FPK which belongs to the Basidiomycota fungal class is one of the most popular medical fungi in China. It has been used for many diseases: cancer, heart diseases, diabetes and so on. However, little study on the pro-apoptotic effect and migration inhibition of FPK chloroform extract (FPKc has been reported and the possible involved mechanism has not been illuminated. METHODOLOGY/PRINCIPAL FINDINGS: Chemical analysis was performed by HPLC which showed ergosterol (ES concentration was 105 µg/mg. MTT assay revealed that FPKc could selectively inhibit SW-480 cells viability with the IC50 of 190.28 µg/ml. Wound healing and transwell assay indicated that FPKc could inhibit the migration of SW-480 cells obviously, FPKc could also dramatically decreased the matrix metalloproteinases-2, 9 (MMP-2 and MMP-9 expression. Annexin V-FITC/PI staining, nuclear Hoechst 33342 staining and DNA fragmentation analysis revealed that FPKc and ES could induce SW-480 cells apoptosis. The apoptosis process closely involved in ROS accumulation and depletion of GSH, activation of caspase 3, poly (ADP-ribose polymerase (PARP degradation. FPKc could also up-regulate P53 expression and thus lead to G1 phase arrest. When SW-480 cells were pretreated with N-acetylcysteine (NAC, the ROS generation, cell viability and apoptotic ratio were partially declined, which indicated that ROS was vertical in the pro-apoptosis process induced by FPKc. Moreover, in the whole process, ES which has been previously found in FPKc had the similar effect to FPKc. Thus we could conclude that ES, as one of the highest abundant components in FPKc, might also be one of the active constituents. CONCLUSION/SIGNIFICANCE: FPKc could inhibit the migration of SW-480 cells, induce SW-480 cells G1 phase arrest and cause ROS-mediated apoptosis effect. And ES might be one of the effective constituents in the whole process.

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

  3. High-resolution seafloor features related to potential gas-hydrate formation off SW Taiwan

    2010-12-01

    The area off SW Taiwan is considered as a high potential area for gas-hydrate formation. The gas-hydrate signature is indicated by the abundant presence of BSR (Bottom-Simulating-Reflector). High methane concentration is also shown in the bottom water near the seafloor. To have a better understanding, we have conducted deep-towed survey of side-scan sonar and sub-bottom profiler in several potential areas. Pockmarks are found in several places. Some are related to gas seeping. The gas seeps are especially obvious in high-resolution sub-bottom profilers. The high pore-pressure due to the charging of the gas has clearly uplifted a top layer of sediments. The pockmarks area usually accompany the presence of authigenic carbonate. In the image of side-scan sonar data, the irregular patterns of strong backscatter signal are associated with the gas seeping or pockmark sites. The presence of pockmarks or gas seeps could be related to structural faults. Because the NW convergence of the Philippine Sea plate relative to the Eurasian plate, the area off SW Taiwan in fact is under compression and has caused folds and faults. These structural faults provide efficient conduits for fluid to migrate upward. Thus, the pockmarks frequently appear near faults. In the water depth of about 450m, the upward gas even goes into water column and creates clear gas plume image in EK 500 data. The gas is inferred to be dissociated from gas-hydrate and can get into the atmosphere. The dissociation of gas-hydrate has probably also induced the instability of the seafloor off SW Taiwan and cuased submarine landslides.

  4. The Influence of SW-GW Exchange on Whole Stream Metabolism Estimates

    In recent years, the dynamic connection between SW-GW has been documented across a wide range of aquatic ecosystems. However this appreciation for dynamic GW exchange has not yet been fully incorporated into our interpretation and quantification of stream ecological processes. To address this, we explored the influence of GW exchange on estimates of net ecosystem productivity (NEP) in real time over 4 months in a snowmelt-dominated catchment in Montana. We examine how metabolism varied seasonally, and assess how the relationship between GW exchange and in-stream processes evolved over the snowmelt-baseflow recession. Traditional 1-station metabolism methods do not fully incorporate hydrologic information into NEP estimates. They are generally insensitive to variation in discharge, and do not incorporate travel times or account for GW exchange. Here we demonstrate that failing to account for both gains and losses can bias NEP estimates and fluxes, particularly in systems with high rates of GW exchange. At our site, accounting for GW exchange during high flow conditions when GW-SW exchange was highest increased instantaneous NEP rates by 2.6 times. Over the entire growing season, this led to a 2.4-fold increase in cumulative growing season NEP. Ecosystem metabolism is a biologically mediated process that is often obfuscated by physical hydrological processes. In order to assess the magnitudes of biotic processes, we must first disentangle them from co-occurring physical processes. We demonstrate that SW-GW exchange is an influential physical process that exerts a strong influence on metabolism estimates. We posit that incorporating GW into metabolism methods will influence NEP estimates across a wide range of systems, particularly those with high rates of exchange or strong seasonality in gains and losses. Incorporating hydrology more fully into stream ecological methods is necessary for accurate understanding and quantification of carbon cycling in streams.

  5. Seismic and gravity constraints on the nature of the basement in the Africa-Eurasia plate boundary: New insights for the geodynamic evolution of the SW Iberian margin

    2014-01-01

    We present a new classification of geological domains at the Africa-Eurasia plate boundary off SW Iberia, together with a regional geodynamic reconstruction spanning from the Mesozoic extension to the Neogene-to-present-day convergence. It is based on seismic velocity and density models along a new transect running from the Horseshoe to the Seine abyssal plains, which is combined with previously available geophysical models from the region. The basement velocity structure at the Seine Abyssal Plain indicates the presence of a highly heterogeneous, thin oceanic crust with local high-velocity anomalies possibly representing zones related to the presence of ultramafic rocks. The integration of this model with previous ones reveals the presence of three oceanic domains offshore SW Iberia: (1) the Seine Abyssal Plain domain, generated during the first stages of slow seafloor spreading in the NE Central Atlantic (Early Jurassic); (2) the Gulf of Cadiz domain, made of oceanic crust generated in the Alpine-Tethys spreading system between Iberia and Africa, which was coeval with the formation of the Seine Abyssal Plain domain and lasted up to the North Atlantic continental breakup (Late Jurassic); and (3) the Gorringe Bank domain, made of exhumed mantle rocks, which formed during the first stages of North Atlantic opening. Our models suggest that the Seine Abyssal Plain and Gulf of Cadiz domains are separated by the Lineament South strike-slip fault, whereas the Gulf of Cadiz and Gorringe Bank domains appear to be limited by a deep thrust fault located at the center of the Horseshoe Abyssal Plain.

    Epigallocatechin-3-gallate (EGCG) is the major polyphenolic constituent in green tea.The aim of this study is to investigate the effects of EGCG on proliferation and migration of the human colon cancer SW620 cells.Methods:Proliferation and migration of SW620 cells were induced by the protease-activated receptor 2-agonist peptide (PAR2-AP,100 μmol/L) or factor Vlla (10 nmol/L),and analyzed using MTT and Transwell assays,respectively.The cellular cytoskeleton was stained with rhodamine-conjugated phalloidin and examined with a laser scanning confocal fluorescence microscope.The expression of caspase-7,tissue factor (TF) and matrix metalloproteinase (MMP)-9 in the cells was examined using QT-PCR,ELISA and Western blot assays.The activation of extracellular signal-regulated kinase 1 and 2 (ERK1/2) and nuclear factor-kappa B (NF-KB) signaling pathways was analyzed with Western blot.Results:Both PAR2-AP and factor Vlla promoted SW620 cell proliferation and migration,and caused cytoskeleton reorganization (increased filopodia and pseudopodia).Pretreatment with EGCG (25,50,75,and 100 μg/mL) dose-dependently blocked the cell proliferation and migration induced by PAR2-AP or factor Vlla.EGCG (100 μg/mL) prevented the cytoskeleton changes induced by PAR2-AP or factor Vlla.EGCG (100 μg/mL) counteracted the down-regulation of caspase-7 expression and up-regulation of TF and MMP-9 expression in the cells treated with PAR2-AP or factor Vlla.Furthermore,it blocked the activation of ERK1/2 and NF-κB (p65/RelA) induced by PAR2-AP or factor Vlla.Conclusion:EGCG blocks the proliferation and migration of SW620 cells induced by PAR2-AP and factor Vlla via inhibition of the ERK1/2 and NF-KB pathways.The compound may serve as a preventive and therapeutic agent for colon cancers.

  8. Kinky thresholds revisited: opportunity costs differ in the NE and SW quadrants.

    Science.gov (United States)

    Eckermann, Simon

    2015-02-01

    Historically, a kinked threshold line on the cost-effectiveness plane at the origin was suggested due to differences in willingness to pay (WTP) for health gain with trade-offs in the north-east (NE) quadrant versus willingness to accept (WTA) cost reductions for health loss with trade-offs in the south-west (SW) quadrant. Empirically, WTA is greater than WTP for equivalent units of health, a finding supported by loss aversion under prospect theory. More recently, appropriate threshold values for health effects have been shown to require an endogenous consideration of the opportunity cost of alternative actions in budget-constrained health systems, but also allocative and displacement inefficiency observed in health system practice. Allocative and displacement inefficiency arise in health systems where the least cost-effective program in contraction has a higher incremental cost-effectiveness ratio (ICER = m) than the most cost-effective program in expansion (ICER = n) and displaced services (ICER = d), respectively. The health shadow price derived by Pekarsky, [Formula: see text] reflects the opportunity cost of best alternative adoption and financing actions in reimbursing new technology with expected incremental costs and net effect allowing for allocative (n < m), and displacement, inefficiency (d < m). This provides an appropriate threshold value for the NE quadrant. In this paper, I show that for trade-offs in the SW quadrant, where new strategies have lower expected net cost while lower expected net effect than current practice, the opportunity cost is contraction of the least cost-effective program, with threshold ICER m. That is, in the SW quadrant, the cost reduction per unit of decreased effect should be compared with the appropriate opportunity cost, best alternative generation of funding. Consequently, appropriate consideration of opportunity cost produces a kink in the threshold at the origin, with the health shadow price in the NE quadrant

  9. SW Sex stars, old novae, and the evolution of cataclysmic variables

    2014-01-01

    The population of cataclysmic variables with orbital periods right above the period gap are dominated by systems with extremely high mass transfer rates, the so-called SW Sextantis stars. On the other hand, some old novae in this period range which are expected to show high mass transfer rate instead show photometric and/or spectroscopic resemblance to low mass transfer systems like dwarf novae. We discuss them as candidates for so-called hibernating systems, CVs that changed their mass transfer behaviour due to a previously experienced nova outburst. This paper is designed to provide input for further research and discussion as the results as such are still very preliminary.

    Numerous epidemiological studies link vascular disorders, such as hypertension, diabetes mellitus, and stroke, with Alzheimer's disease (AD). Hypertension, specifically, is an important modifiable risk factor for late-onset AD. To examine the link between midlife hypertension and the onset of AD later in life, we chemically induced chronic hypertension in the TgSwDI mouse model of AD in early adulthood. Hypertension accelerated cognitive deficits in the Barnes maze test (Phypertension induced hippocampal neurodegeneration at an early age in this mouse line (43% reduction in the dorsal subiculum; P<0.05), establishing this as a useful research model of AD with mixed vascular and amyloid pathologies.

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

    2017-01-01

    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.

  14. Identification of the Novel TMEM16A Inhibitor Dehydroandrographolide and Its Anticancer Activity on SW620 Cells.

    Directory of Open Access Journals (Sweden)

    Yujie Sui

    Full Text Available TMEM16A, a calcium-activated chloride channel (CaCC, is highly amplified and expressed in human cancers and is involved in the growth and metastasis of some malignancies. Inhibition of TMEM16A represents a novel pharmaceutical approach for the treatment of cancers and metastases. The purpose of this study is to identify a new TMEM16A inhibitor, investigate the effects of this inhibitor on the proliferation and metastasis of TMEM16A-amplified SW620 cells, and to elucidate the underlying molecular mechanism in vitro. We identified a novel small-molecule TMEM16A inhibitor dehydroandrographolide (DP. By using patch clamp electrophysiology, we showed that DP inhibited TMEM16A chloride currents in Fisher rat thyroid (FRT cells that were transfected stably with human TMEM16A and in TMEM16A-overexpressed SW620 cells but did not alter cystic fibrosis transmembrane conductance regulator (CFTR chloride currents. Further functional studies showed that DP suppressed the proliferation of SW620 cells in a dose- and time-dependent manner using MTT assays. Moreover, DP significantly inhibited migration and invasion of SW620 cells as detected by wound-healing and transwell assays. Further mechanistic study demonstrated that knockdown of human TMEM16A decreased the inhibitory effect of DP on the proliferation of SW620 cells and that TMEM16A-dependent cells (SW620 and HCT116 were more sensitive to DP than TMEM16A-independent cells (SW480 and HCT8. In addition, we found that treatment of SW620 cells with DP led to a decrease in TMEM16A protein levels but had no effect on TMEM16A mRNA levels. The current work reveals that DP, a novel TMEM16A inhibitor, exerts its anticancer activity on SW620 cells partly through a TMEM16A-dependent mechanism, which may introduce a new targeting approach for an antitumour therapy in TMEM16A-amplified cancers.

    2014-12-01

    The USDA Southwest (SW) Climate Hub was created in February 2014 to develop risk adaptation and mitigation strategies for coping with climate change effects on agricultural productivity. There are seven regional hubs across the country with three subsidiary hubs. The SW Climate Hub Region is made up of six states: New Mexico, Arizona, Utah, Nevada, California and Hawaii (plus the Trust Territories of the Pacific Islands). The SW Climate Hub has a subsidiary hub located in Davis, California. The Southwest region has high climatic diversity, with the lowest and highest average annual rainfall in the U.S.(6.0 cm in Death Valley, CA and 1168 cm at Mt. Waialeale, HI). There are major deserts in five of the six states, yet most of the states, with exception of Hawaii, depend upon the melting of mountain snowpacks for their surface water supply. Additionally, many of the agricultural areas of the SW Regional Hub depend upon irrigation water to maintain productivity. Scientific climate information developed by the Hub will be used for climate-smart decision making. To do this, the SW Regional Hub will rely upon existing infrastructure of the Cooperative Extension Service at Land-Grant State Universities. Extension service and USDA-NRCS personnel have existing networks to communicate with stakeholders (farmers, ranchers, and forest landowners) through meetings and workshops which have already started in the six states. Outreach through the development of a weather and climate impact modules designed for seventh grade students and their teachers will foster education of future generations of rural land managers. We will be synthesizing and evaluating existing reports, literature and information on regional climate projections, water resources, and agricultural adaptation strategies related to climate in the Southwest. The results will be organized in a spatial format and provided through the SW Hub website (http://swclimatehub.info) and peer-reviewed articles.

    We probe the chemical and energetic conditions in dense gas created by radiative feedback through observations of multiple CO, HCN and HCO$^+$ transitions toward the dense core of M17 SW. We used the dual band receiver GREAT on board the SOFIA airborne telescope to obtain maps of the $J=16-15$, $J=12-11$, and $J=11-10$ transitions of $^{12}$CO. We compare these maps with corresponding APEX and IRAM 30m telescope data for low- and mid-$J$ CO, HCN and HCO$^+$ emission lines, including maps of the HCN $J=8-7$ and HCO$^+$ $J=9-8$ transitions. The excitation conditions of $^{12}$CO, HCO$^+$ and HCN are estimated with a two-phase non-LTE radiative transfer model of the line spectral energy distributions (LSEDs) at four selected positions. The energy balance at these positions is also studied. We obtained extensive LSEDs for the CO, HCN and HCO$^+$ molecules toward M17 SW. The LSED shape, particularly the high-$J$ tail of the CO lines observed with SOFIA/GREAT, is distinctive for the underlying excitation conditions...

    2009-12-01

    The Tomar-Badajoz-Córdoba shear Zone (TBCSZ) is a major structural element located in SW-Iberia. This is considered a suture that separates the Central Iberian Zone (CIZ) in NE and Ossa Morena Zone (OMZ) in SW. It is at least 380km in length and 10 to 20km width. It is a left lateral transpressive flower structure. The strike-slip displacement decays from SE to NW. Its axial zone includes a high grade metamorphic rock unit known as the Central Unit (CU) containing eclogites, and also suture lithotypes as ophiolites. It has been interpreted as a Variscan suture or a reworked Cadomian suture in intraplate regime during the Variscan cycle. This important structure has been imaged by 2 deep seismic reflection transects, the IBERSEIS in 2003 and more recently by ALCUDIA. The good quality of the seismic data sets constrains the internal architecture of this transpressional zone imaging a crustal scale flower structure. The structure features a north dipping wedge limited by two bands of reflectors that reach the middle crust (5 s). Beneath that and slightly to the north a wedge of relatively high amplitude reflectivity dips to the south into the mantle for 10-15 km. This structure is most probably the seismic signature of a complex structure result of deformation associated to a strike slip fault.

  18. An Orbital Stability Study of the Proposed Companions of SW Lyncis

    Hinse, Tobias C; Wittenmyer, Robert A

    2014-01-01

    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 sub-stellar 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 behaviour. 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...

    Full Text Available Benchmarking of modules is necessary as it helps to note any changes on the operation of the modules when in operation outdoors. The equipment needed to do this has been found to be very expensive hence the need of cheaper methods. This paper tries to show how this can be achieved using outdoor conditions and an I/V measuring instrument PVPM1000. SW80 photovoltaic modules were tested using outdoor conditions. The current and voltage measurements were taken at solar noon and converted to the standard test conditions (STC, 1000 Wm-2 AM 1.5 and 25°C. These normalized values were in turn taken as bench mark values of the modules. Future measurements can then be taken at solar noon and compared to benchmark values; any variations in performance can then be noted. The variations on benchmark values as compared to the manufacturer STC values for SW80 type module were noted. The measurements were carried out under typical South Africa meteorological conditions.

    Stanishev, V; Genkov, V

    2006-01-01

    Aims: We present a photometric study of the deeply eclipsing SW Sex-type nova-like cataclysmic variable star BH Lyn Methods: Time-resolved V-band CCD photometry was obtained for seven nights between 1999 and 2004. Results: We determined 11 new eclipse timings of BH Lyn and derived a refined orbital ephemeris with an orbital period of 0.155875577(14) day. During the observations, BH Lyn was in high-state with V~15.5 mag. The star presents ~1.5 mag deep eclipses with mean full-width at half-flux of 0.0683(+/-0.0054)P_orb. The eclipse shape is highly variable, even changing form cycle to cycle. This is most likely due to accretion disc surface brightness distribution variations, most probably caused by strong flickering. Time-dependent accretion disc self-occultation or variations of the hot spot(s) intensity are also possible explanations. Negative superhumps with period of ~0.145 day are detected in two long runs in 2000. A possible connection between SW Sex and negative superhump phenomena through the presenc...

  1. Disk-Anchored Magnetic Propellers A Cure for the SW Sex Syndrome

    CERN Document Server

    Horne, K

    1999-01-01

    In AE Aqr, magnetic fields transfer energy and angular momentum from a rapidly spinning white dwarf to material in the gas stream from the companion star, with the effect of spinning down the white dwarf while flinging the gas stream material out of the binary system. This magnetic propeller produces a host of observable signatures, chief among which are broad single-peaked flaring emission lines with phase-shifted orbital kinematics. SW Sex stars have accretion disks, but also broad single-peaked phase-shifted emission lines similar to those seen in AE Aqr. We propose that a magnetic propeller similar to that which operates in AE Aqr is also at work in SW Sex stars -- and to some extent in all nova-like systems. The propeller is anchored in the inner accretion disk, rather than or in addition to the white dwarf. Energy and angular momentum are thereby extracted from the inner disk and transferred to gas stream material flowing above the disk, which is consequently pitched out of the system. This provides a n...

    We studied phycoerythrin (PE) in human SW480 tumor cells and the underlying molecular mechanisms of action. PE inhibited cell proliferation as evidenced by CCK-8 assay. The IC50 values of phycoerythrin were 48.2 and 27.4 µg/ml for 24 and 48 h of exposure, respectively. PE induced apoptosis and cell cycle arrest in SW480 cells as observed under electron microscopy and with flow cytometry. Apoptosis increased from 5.1 (controls) to 39.0% in 80.0 µg/ml PE-treated cells. Differences in protein expression were identified using proteomic techniques. Protein spots (1018±60 and 1010±60) were resolved in PE-treated and untreated group. Forty differential protein spots were analyzed with MALDI-TOF-MS, including GRP78 and NPM1. The expression as measured by qPCR and western blotting agreed with data from two-dimensional electrophoresis. GRP78, NPM1, MTHSP75, Ezrin and Annexin A2 were decreased and HSP60 was increased after PE treatment, indicating that PE may target multiple proteins to induce apoptosis.

  3. Echinacoside Induces Apoptosis in Human SW480 Colorectal Cancer Cells by Induction of Oxidative DNA Damages

    2015-06-01

    Full Text Available Echinacoside is a natural compound with potent reactive oxygen species (ROS-scavenging and anti-oxidative bioactivities, which protect cells from oxidative damages. As cancer cells are often under intense oxidative stress, we therefore tested if Echinacoside treatment would promote cancer development. Surprisingly, we found that Echinacoside significantly inhibited the growth and proliferation of a panel of cancer cell lines. Treatment of the human SW480 cancer cells with Echinacoside resulted in marked apoptosis and cell cycle arrest, together with a significant increase in active caspase 3 and cleaved PARP, and upregulation of the G1/S-CDK blocker CDKN1B (p21. Interestingly, immunocytochemistry examination of drug-treated cancer cells revealed that Echinacoside caused a significant increase of intracellular oxidized guanine, 8-oxoG, and dramatic upregulation of the double-strand DNA break (DSB-binding protein 53BP1, suggesting that Echinacoside induced cell cycle arrest and apoptosis in SW480 cancer cells via induction of oxidative DNA damages. These results establish Echinacoside as a novel chemical scaffold for development of anticancer drugs.

  4. The Shortwave (SW) Clear-Sky Detection and Fitting Algorithm: Algorithm Operational Details and Explanations

    Long, CN; Gaustad, KL

    2004-01-31

    This document describes some specifics of the algorithm for detecting clear skies and fitting clear-sky shortwave (SW) functions described in Long and Ackerman (2000). This algorithm forms the basis of the ARM SW FLUX ANAL 1Long VAP. In the Atmospheric Radiation Measurement (ARM) case, the value added procedures (VAP) can be described as having three parts: a “front end,” a “black box,” and a “back end.” The “front end” handles the file management of the processing, what range of data files to process in the run, which configuration file to use for each site, extracting the data from the ARM NetCDF files into an ASCII format for the code to process, etc. The “back end” produces ARM-format NetCDF files of the output and other file management. The “black box” is the processing code(s), and is what is discussed in this document. Details on the “front” and “back” ends of the ARM VAP are presented elsewhere.

    Full Text Available Lectins comprise a heterogeneous class of proteins that recognize the carbohydrate moieties of glycoconjugates with high specificity. Numerous studies have shown that lectins are capable of recognizing specific carbohydrate moieties displayed by malignant cells or tissues. The present work was performed to investigate the effects of tepary bean (Phaseolus acutifolius lectins on proliferation, colony formation, and alteration of DNA synthesis of human malignant cells. Tepary bean lectin showed dose dependent  effects on the inhibition of viability as well as on colony formation in two human malignant cells lines (C33-A, Sw480; By contrast, tepary bean lectin only showed significant effects on DNA synthesis on Sw480 cells. Our results provide evidence of the anti- proliferative and cytotoxic effects of the tepary bean lectins on C33-A and Sw480 cells lines.

    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.

    The Eastern Mediterranean has been an area of intense human occupation since the early Neolithic. However, contrary to many temperate environments in NW Europe, human pressure on the landscape did not follow a linear trajectory from the Neolithic to the present, but is rather characterised by cycles of land cover expansion and contraction. Here, we provide a synthesis of human-climate-environment interactions in the region of the antique city of Sagalassos in the Taurus mountain range of SW Turkey. The combination of archaeological, palynological and geomorphological data, together with geochemical sediment provenancing and spatial modelling techniques, enabled to reconstruct the relative importance of anthropogenic pressure and climatic changes on the environment. The sensitivity of the landscape towards anthropogenic disturbance is strongly controlled by the geomorphic-tectonic setting, as well as by important feedback mechanisms in the soil system. The first major clearing of the landscape in the Iron Age led to a peak in soil erosion, but also to soil exhaustion limiting erosion rates in subsequent periods. Soil erosion and sediment delivery is more limited during the main occupation phases of the Roman Imperial Period. Periods with more favorable climate in the Roman and Mid-Byzantine periods resulted in the occupation of more isolated parts of the territory (i.e. higher up in the mountains), whilst a decrease in human pressure can be observed during the Early Byzantine and Ottoman periods related to less favorable conditions. Such smaller and short-lasting bursts of human occupation did not significanlty impact the environment. Only in the last two hundred years, human pressure reached similar values as those encountered in the classical period.

  10. Trace element partitioning and soil particle characterisation around mining and smelting areas at Tharsis, Riotinto and Huelva, SW Spain

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

    The porcine RN locus affects muscle glycogen content and meat quality. We previously mapped the RN locus to chromosome 15. This study describes the identification of polymorphisms for four class I and four class II markers located in the RN region. Resource families were genotyped with F-SSCP markers (fluorescent single strand conformation polymorphism) and microsatellite markers. Subsequent multipoint linkage analysis revealed the order FN1-IGFBP5-S1000-S1001-IL8RB-VIL1-RN-Sw936-Sw906. The gene order is identical to the previously reported porcine RH map of the same region. The described map will facilitate positional cloning of the RN gene.

    Using plaquette and Symanzik improved gauge action and stout link clover fermions we determine the improvement coefficient c{sub SW} in one-loop lattice perturbation theory from the off-shell quark-quark-gluon three-point function. In addition, we compute the coefficients needed for the most general form of quark field improvement and present the one-loop result for the critical hopping parameter {kappa}{sub c}. We discuss mean field improvement for c{sub SW} and {kappa}{sub c} and the choice of the mean field coupling for the actions we have considered. (orig.)

    We prove that the family of non-linear $W$-algebras $SW(3/2,2)$ which are extensions of the $N=1$ superconformal algebra by a primary supercurrent of conformal weight $2$ can be realized as a quantum Hamiltonian reduction of the Lie superalgebra $osp(3|2)$. In consequence we obtain an explicit free field realization of the algebra in terms of the screening operators. At central charge $c=12$ the $SW(3/2,2)$ superconformal algebra corresponds to the superconformal algebra associated to sigma models based on eight-dimensional manifolds with special holonomy $Spin(7)$, i.e., the Shatashvili-Vafa $Spin(7)$ superconformal algebra.

    The southern Satakunta area lies on the west coast of Finland, mainly covering the mainland (with main towns Pori and Rauma), but also including the coastal archipelago and part of the Bothnian Sea. Near the centre of the area lies the island of Olkiluoto, on which Finland's site for a deep repository for spent nuclear fuel is located. The purpose of the present report is to compile and interpret all available geological and geophysical data relevant to understanding the regional geological setting of the Olkiluoto site. The area described is covered by four 1:100 000 scale geological map sheets, published by the Geological Survey of Finland, which, together with low-altitude aeromagnetic maps, provide the basis for a new 1:250 000 geological map compilation. This shows that the bedrock of southern Satakunta can be subdivided into three main zones: a pelitic migmatite belt in the southwest, a central, NW-SE trending area of sandstone, and a psammitic migmatite belt in the northeast. The migmatite belts formed during the Svecofennian orogeny, 1900-1800 Ma ago (Palaeoproterozoic). The sandstone area is the remnant of an alluvial basin, preserved now in a NW-SE trending graben, bounded on both sides by normal fault zones. The sandstones are thought to be at least 1400-1300 Ma old (Mesoproterozoic), and they are cut by Postjotnian olivine diabase dykes, 1270-1250 Ma in age. The Svecofennian migmatite belts show a complex history of formation, with various phases of anatexis/metamorphism, deformation and intrusion. In the pelitic migmatite belt, in which the Olkiluoto site is situated, four phases of ductile deformation (D-D4) and two phases of regional highT/lowP metamorphism and migmatite formation can be recognised, together with synorogenic (tonalite, granodiotite) and late orogenic ( potassium granite) intrusions. Subsequently, this very heterogeneous complex was intruded by anorogenic rapakivi granites, with ages 1580-1550 Ma. One pluton, the Eurajoki stock

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

    The structural relationship between the Qaidam Basin and Qimen Tagh-Eastern Kunlun Range holds important implications for evaluating the formation mechanism of the Tibetan Plateau. Various models have been proposed to reveal the structural relationship, although controversies remain. To address these issues, we analysed the seismic and lithologic data of the Kunbei fault system (i.e. the Kunbei, Arlar and Hongliuquan faults), which lies to the north of the Qimen Tagh-Eastern Kunlun Range within the SW Qaidam Basin. Based on the regional geological framework and our kinematic analyses, we propose that the Cenozoic tectonic evolution of the Kunbei fault system can be divided into two stages. From the Early Eocene to the Middle Miocene, the system was characterized by left-lateral strike-slip faults and weak south-dipping thrust faults based on the flower structure in the seismic section, which is an apparent strike-slip deformation that was identified in the -1510-ms time slice and the root-mean-square amplitude attribute slice. This strike-slip motion was generated by the uplift of the Tibetan Plateau caused by the onset of the Indian-Eurasian collision. Since the Middle Miocene, the Kunbei fault system has undergone intense south-dipping thrusting, and a nearly 2.2-km uplift has been observed in the hanging wall in the Arlar fault. The south-dipping thrusting is the far-field effect of the full collision that occurred between the Indian-Eurasian plates. The lake area in the SW Qaidam Basin has been shrinking since the Middle Miocene and presents widespread delta and fluvial deposits, which are consistent with the proposed tectonic evolution.

Las localidades ocupadas se consideraron “dominios vitales reproductivos” cuando se pudo comprobar el emparejamiento o la nidificación, o cuando se registró presencia de individuos en un mínimo de tres visitas consecutivas. Se vigiló el desarrollo de la reproducción en nidos activos durante mayo y junio. Se detectaron y cartografiaron 21 "dominios vitales reproductivos", distribuidos fundamentalmente a lo largo de las franjas oriental y meridional del área de estudio. Las determinantes ambientales relacionadas positivamente con la presencia de "dominios vitales reproductivos" fueron elevada cobertura arbolada, estructura madura, superficies de haya Fagus sylvatica, bosque mixto caducifolio y pino laricio Pinus nigra, y parcelas forestales poco fragmentadas. Las plantaciones de pino de Monterrey P. radiata y las alturas bajas del arbolado se seleccionaron negativamente. Las parcelas de alimentación preferidas incluyeron proporciones de roble americano Quercus rubra y plantaciones de pino laricio. Se detectaron trece nidos activos. Todos los nidos salvo dos fueron excavados en hayas.

    This is the second paper of a series of two concerning strong ground motion in SW Iberia due to earthquakes originating from the adjacent Atlantic area. The aim of this paper is to use the velocity model that was proposed and validated in the companion paper for seismic intensity modelling of the 1969 (Ms = 8.0) and 1755 (M = 8.5-8.7) earthquakes. First, we propose a regression to convert simulated values of Peak Ground Velocity (PGV) into Modified Mercalli Intensity (MMI) in SW Iberia, and using this regression, we build synthetic isoseismal maps for a large (Ms = 8.0) earthquake that occurred in 1969. Based on information on the seismic source provided by various authors, we show that the velocity model effectively reproduces macroseismic observations in the whole region. We also confirm that seismic intensity distribution is very sensitive to a small number of source parameters: rupture directivity, fault strike and fault dimensions. Then, we extrapolate the method to the case of the great (M = 8.5-8.7) 1755 earthquake, for a series of hypotheses recently proposed by three authors about the location of the epicentral region. The model involving a subduction-related rupture in the Gulf of Cádiz results in excessive ground motion in northern Morocco, suggesting that the source of the 1755 earthquake should be located further west. A rupture along the western coast of Portugal, compatible with an activation of the passive western Iberian margin, would imply a relatively low average slip, which, alone, would could not account for the large tsunami observed in the whole northern Atlantic ocean. A seismic source located below the Gorringe Bank seems the most likely since it is more efficient in reproducing the distribution of high intensities in SW Iberia due to the 1755 earthquake.

    Since vectorized regroup instructions sire comparatively complex whereas different instructions correspond to different delays, it is hard to find out a uniform and efficient vector regroup algorithm. The paper analyzes shifting and insertion/extraction instructions that are offered by domestic produced CPU SW-1600, and presents an optimal algorithm that only depends on shifting or insertion/extraction instructions to realize vector regroup as well as an efficient algorithm that integrates the two types of instructions to realize vector regroup. At last it is proven by experiments that the algorithms can better vectorize programs. The speedup ratio for integer type values reaches 7.31 while that for complex double precision float type programs reaches 1. 83.%由于向量化重组指令比较复杂并且不同指令有不同的延迟,从而难以寻找一种统一高效的向量重组算法.对国产CPUSW-1600提供的移位和插入提取指令进行了分析,提出单独依靠移位或插入提取指令实现向量重组的最优算法,并综合这两类指令实现向量重组的高效算法.最后通过实验证明该算法可以较好地对程序进行向量化,对整型数据的加速比达到7.31,对复杂的双精度浮点型程序的加速比也达到1.83.

    Full Text Available Nuclear DNA content for the adult plants grown in a greenhouse and in vitro young plantlets of the pigeon orchid (Dendrobium crumenatum Sw. was analyzed using flow cytometry. The resulting 2C DNA values ranged from 2.30±0.14 pgto 2.43±0.06 pg. However, nuclear DNA ploidy levels of long-term in vitro plantlets were found to be triploid and tetraploid.These ploidy levels were confirmed by chromosome counting. Tetraploid individuals (2n = 4x = 76 had approximately two times DNA content than diploid (2n = 2x = 38 individuals. This variation may be due to prolonged cultivation and thepresence of exogenous plant growth regulators.

    The chemical and energetic conditions created by radiative feedback are probed with observations of multiple molecular transitions toward M17 SW. Extensive maps, including the 12CO J = 16 → 15, J = 12 → 11, and J = 11 → 10 lines, as well as the HCN J = 8 → 7 and HCO+ J = 9 → 8 transitions, were obtained with the dual band receiver GREAT on board the SOFIA airborne telescope, and with the ground based APEX and IRAM 30 m telescopes. These data provide extensive line spectral energy distributions (LSEDs) of the CO, HCN and HCO+ molecules (and their isotopologues). The excitation conditions of the three species are estimated simultaneously using the same density and temperature in a two-phase non-LTE radiative transfer model of the LSEDs.

    The geochemical character of two chert formations from the Pyrenean mountain range (SW Europe) was established by PIXE analyses. While it was not possible to distinguish the formations through reference to major and minor elements, some variations were revealed at the trace elemental level. In order to determine if these elements are associated with the Si matrix or to the contents of a specific inclusion, elemental maps were acquired and the elemental composition of the identified inclusions were also determined. As a result, Sr, Ni and Zn are better represented in Montgaillard samples while Y, Hf, W and Zr are typical of Montsaunès cherts. Thanks to elemental maps it has been possible to determine that most of these characteristic elements are usually related to a specific inclusion content.

    Wave prediction and hindcast studies are important in ocean engineering, coastal infrastructure development and management. In view of sparse and infrequent in-situ observations, model derived hindcast wave data can be used for the assessment of wave climate in offshore and coastal areas. In the present study, MIKE 21 SW Model has been used to carry out wave hindcast experiments in the Indian Ocean. Model runs have been made for the year 2005 using QuickSCAT scatterometer winds blended with ECMWF model winds. In order to study the impact of southern ocean swells, the model has been run in two different domains, with the southern boundary being shifted far south for the Domain 60S model. The model simulated wave parameters have been validated by comparing with buoy and altimeter data and various statistical yardsticks have been employed to quantify the validation. Possible reason for the poorer performance of the model in the Arabian Sea has also been pointed out.

  6. Late Pleistocene Climate Events and The Origin of Agriculture In SW Asia

    Science.gov (United States)

    Rossignol-Strick, M.

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

    Kangiella koreensis (Yoon et al. 2004) is the type species of the genus and is of phylogenetic interest because of the very isolated location of the genus Kangiella in the gammaproteobac-terial order Oceanospirillales. K. koreensis SW-125T is a Gram-negative, non-motile, non-spore-forming bacterium isolated from tidal flat sediments at Daepo Beach, Yellow Sea, Ko-rea. Here we describe the features of this organism, together with the complete genome se-quence, and annotation. This is the first completed genome sequence from the genus Kangiel-la and only the fourth genome from the order Oceanospirillales. This 2,852,073 bp long sin-gle replicon genome with its 2647 protein-coding and 48 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

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

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

    In 2012-2014 we acquired 1569 CCD BVIc frames for the RR Lyrae type variable SW Dor with the 76-cm telescope of the South African Astronomical Observatory (SAAO) and 1-m telescopes of Las Cumbres Observatory Global Telescope network (LCOGT). Our observations showed a large scatter in the resulting phased light curve, especially near maximum brightness, which allowed us to reveal the Blazhko effect with a period of ˜80.9d. To study the pulsation period changes, we used all the available observations including the 1299 magnitude estimates from the digitized plate library of Harvard University (the DASCH project), which allowed us to construct the O-C diagram spanning a 125-year long time interval and discover for the first time at least three abrupt changes of the pulsation period.

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

    2011-01-01

    Tomato spotted wilt virus (TSWV) causes severe economic losses in many crops worldwide and often overcomes resistant cultivars used for disease control. Comparison of nucleotide and amino acid sequences suggested that tomato resistance conferred by the gene Sw-5 can be overcome by the amino acid substitution C to Y at position 118 (C118Y) or T120N in the TSWV movement protein, NSm. Phylogenetic analysis revealed that substitution C118Y has occurred independently three times in the studied isolates by convergent evolution, whereas the substitution T120N was a unique event. Analysis of rates of non-synonymous and synonymous changes at individual codons showed that substitution C118Y was positively selected.

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

    Ingestion of anthropogenic debris represents an important threat to marine turtle populations. Information has been limited to inventories of debris ingested and its consequences, but why ingestion occurs and the conditions that enable it are less understood. Here we report on the occurrence of plastic ingestion in young green turtles (Chelonia mydas) inhabiting the Río de la Plata (SW Atlantic). This estuarine area is characterized by a frontal system that accumulates anthropogenic debris. We explored exposure of green turtles to plastic and its ingestion via debris distribution, habitat use and digestive tract examination. Results indicated that there is considerable overlap of frontal accumulated plastic and core foraging areas of the animals. Exposure results in ingestion, as shown by the high frequency of plastic found in the digestive tracts. The Río de la Plata estuarine front is an area of conservation concern for young green turtles.

  19. High-pressure metamorphism in the Early Variscan subduction complex of the SW Iberian Massif

    Several units exposed in the boundary area of the Ossa Morena Zone (OMZ) and the South Portuguese Zone (SPZ) preserve petrographic and thermobarometric evidence for an early metamorphic episode (M1), developed under a high-P, low to intermediate-T gradient, related to Early Variscan subduction in the SW Iberian Massif. In the OMZ, these are the Cubito-Moura Unit (Pmin ~ 9.2 kbar and T = 395 ± 45 °C), blueschists from its basal mélange (Pmin ~ 12.4 kbar and T = 310 ± 11 °C), and the underlying Fuenteheridos Group (P = 10.9 ± 0.4 kbar and T = 449 ± 31 °C). The equivalent units in the SPZ are the La Minilla Formation (P = 8.7 ± 0.4 kbar and T = 388 ± 16 °C) and the lawsonite pseudomorphs-bearing Pulo do Lobo Formation. All these units formed part of an approximately NE verging orogenic wedge (present coordinates) developed by the accretion of subducted slabs of the outermost margin of Gondwana and other elements of the Rheic Ocean realm, from at least the Middle Devonian to the lowermost Tournaisian. High-pressure rocks were subsequently emplaced on more internal zones of the OMZ that only experienced a younger high-T, low to intermediate-P metamorphism (M2). This high-T event was coeval with magmatic activity from the uppermost Devonian to the Middle Mississippian, probably as a consequence of transtensional lithospheric thinning and/or delamination of the lower crust and mantle lithosphere of the Gondwana margin. Pre-Late Devonian synorogenic sedimentation in forearc and back-arc basins of the subduction complex evolved to a Late Devonian-Middle Mississippian foreland basin system in early collisional stages. Finally, a new Middle-Late Mississippian fold-and-thrust belt with opposite (SW) vergence and new foreland basins developed during late collisional stages.

    The Rheic Ocean suture resulted from pre-Carboniferous oceanic subduction followed by Late Devonian-Carboniferous Variscan collision. In SW Iberia, this suture has been classically located along the boundary between the Ossa-Morena and South Portuguese Zones based on the presence of three units: (i) a conspicuous metamafic unit (Beja-Acebuches) that crops out along this boundary and has been interpreted as a pre-Carboniferous Rheic Ocean ophiolite; (ii) a low-grade metasedimentary unit with minor mid-ocean ridge basalt-like lithologies (Pulo do Lobo unit), thought to represent a Rheic Ocean subduction-related accretionary prism; and (iii) the allochthonous Cubito-Moura unit that contains high-pressure and ophiolitic-like rocks. We report new structural and geochronological data that allow us to reinterpret the origin and internal structure of the Beja-Acebuches and the Pulo do Lobo units. Thus, both the Beja-Acebuches protoliths and the Pulo do Lobo metabasalts would have been formed in the context of an intracollisional extensional stage that interrupted the Variscan collision at early Carboniferous time, after the Rheic Ocean consumption, and the first continental collision. Later on, collision was resumed in an oblique left-lateral regime that gave way to coeval frontal (folds and thrusts) and lateral (shear zones and strike-slip faults) structures, with variable pressure-temperature conditions and space distribution along time. As a consequence of the superposition of transtension and complex transpression, the Rheic suture in SW Iberia has an obscure nearly cryptic appearance.

  1. Possible petrological controls on the location and time scale of slow slip in SW Japan

    To examine the possibility that there was a petrological control on the location and nature of episodic tremor and slip (ETS), we compared the petrological characteristics of wedge mantle material to the results of recent geophysical observations in the Shikoku area, southwest Japan. This study revealed a close relationship between predicted mineral assemblages in the mantle wedge and the characteristics of slow slip behaviour recorded in the Shikoku area: Short-term ETSs take place in the antigorite +olivine stability field and silent long-term slow slip events (SSEs) take place in the antigorite+brucite stability field. The petrology of the mantle wedge may be an important control on the fluid pressure along the subduction interface and influence the time scales of SSEs. The Cretaceous Sanbagawa oceanic subduction complex of SW Japan preserves fragments of the former mantle wedge in contact with subducted slab units. P-T paths and peak P-T conditions show this belt formed as the result of subduction of a young slab under relatively warm conditions. These characteristics make the Sanbagawa belt a good analogue to modern warm subduction zones such as the Philippine Sea subduction zone beneath SW Japan and offer the possibility of directly examining the former plate boundary. Mantle wedge units derived from shallow depths show evidence for widely developed primary brucite and antigorite. In contrast, units derived from greater depths and higher peak temeratures consist dominantly of antigorite and olivine. Observations of the natural serpentinites suggest that the shallow serpentinite with brucite shows higher absorbency of water and provides fluid pathways that can reduce the fluid pore pressure on the subduction boundary.

    Full Text Available The structural integrity of cerebral vessels is compromised during ageing. Abnormal amyloid (Aβ deposition in the vasculature can accelerate age-related pathologies. The cerebrovascular response associated with ageing and microvascular Aβ deposition was defined using quantitative label-free shotgun proteomic analysis. Over 650 proteins were quantified in vessel-enriched fractions from the brains of 3 and 9 month-old wild-type (WT and Tg-SwDI mice. Sixty-five proteins were significantly increased in older WT animals and included several basement membrane proteins (nidogen-1, basement membrane-specific heparan sulfate proteoglycan core protein, laminin subunit gamma-1 precursor and collagen alpha-2(IV chain preproprotein. Twenty-four proteins were increased and twenty-one decreased in older Tg-SwDI mice. Of these, increases in Apolipoprotein E (APOE and high temperature requirement serine protease-1 (HTRA1 and decreases in spliceosome and RNA-binding proteins were the most prominent. Only six shared proteins were altered in both 9-month old WT and Tg-SwDI animals. The age-related proteomic response in the cerebrovasculature was distinctly different in the presence of microvascular Aβ deposition. Proteins found differentially expressed within the WT and Tg-SwDI animals give greater insight to the mechanisms behind age-related cerebrovascular dysfunction and pathologies and may provide novel therapeutic targets.

    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.

    AIM: To investigate the effects of aspirin (acetylsalicylic acid) on proliferation and apoptosis of colorectal can- cer cell line $W480 and its mechanism. METHODS: Cyclooxygenase (COX)-2 negative colorec- tal cancer cell line SW480 was treated with aspirin at concentrations of 2.5 retool/L, 5.0 retool/L, 10.0 mmol/L for different periods in vitro. Anti-proliferation effect of aspirin on SW480 was detected by 3-(4,5-dimeth- ylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Cell cycle and apoptosis were observed by flow cytometry (FCM). Transmission electron microscope (TEM) was used for morphological study. Apoptosis-as- sociated genes were detected by immunohistochemical staining and Western blotting. RESULTS: Aspirin inhibited SW480 proliferation and induced apoptosis in a dose- and time-dependent manner. Treatment with different concentrations of aspirin significantly increased the proportions of cells at the G0/G1 phase and decreased the proportions of cells at the S- and G2/M phases in a concentration- dependent manner. Aspirin not only induced apoptosis but also caused cell necrosis at a high concentration as well. After treatment with aspirin, SW480 cells displayed typically morphological features of apoptosis and necrosis under TEM, and increased the Bcl-2 expression in cells, but the expression of Bax was down regulated. CONCLUSION: Aspirin inhibits proliferation and induces apoptosis of SW480 cells. Its anti-tumor mechanism may arrest cell cycle and shift Bax/Bcl-2 balance in cells.

    Only a limited number of dominant resistance genes acting against plant viruses have been cloned, and further functional studies of these have been almost entirely limited to the resistance genes Rx against Potato virus X (PVX) and N against Tobacco mosaic virus (TMV). Recently, the cell-to-cell movement protein (NSM ) of Tomato spotted wilt virus (TSWV) has been identified as the avirulence determinant (Avr) of Sw-5b-mediated resistance, a dominant resistance gene which belongs to the class of SD-CC-NB-LRR (Solanaceae domain-coiled coil-nucleotide-binding-leucine-rich repeat, SD-CNL) resistance genes. On transient expression of the NSM protein in tomato and transgenic Nicotiana benthamiana harbouring the Sw-5b gene, a hypersensitive cell death response (HR) is triggered. Here, it is shown that high accumulation of the Sw-5b protein in N. benthamiana leaves, achieved by co-expression of the Sw-5b protein with RNA silencing suppressors (RSSs), leads to auto-activity in the absence of NSM . In a similar approach, Sw-5a, the highest conserved paralogue of Sw-5b from Solanum peruvianum, also triggered HR by auto-activation, whereas the highest conserved orthologue from susceptible S. lycopersicum, named Sw-5a(S) , did not. However, neither of the last two homologues was able to trigger an NSM -dependent HR. Truncated and mutated versions of these Sw-5 proteins revealed that the NB-ARC [nucleotide-binding adaptor shared by Apaf-1 (from humans), R proteins and CED-4 (from nematodes)] domain is sufficient for the triggering of HR and seems to be suppressed by the SD-CC domain. Furthermore, a single mutation was sufficient to restore auto-activity within the NB-ARC domain of Sw-5a(S) . When the latter domain was fused to the Sw-5b LRR domain, NSM -dependent HR triggering was regained, but not in the presence of its own Sw-5a(S) LRR domain. Expression analysis in planta revealed a nucleocytoplasmic localization pattern of Sw-5b, in which the SD-CC domain seems to be

    Full Text Available A nodal segment culture was developed in order to assess Solanum torvum Sw. regeneration and solasodine levels. The influence of auxins (indoleacetic acid, 1-Naphthaleneacetic acid and benzyl adenine on S. torvum growth in micropropagation was investigated. A nodal segment culture was initiated with seeds germinated in MS basal medium added of GA3 and grown in different concentrations of IAA, IAA + BAP and NAA + BAP. Sixty-day-old plants from the in vitro culture were collected, frozen and lyophilized; then, the methyl orange method was used to quantify solasodine for the spectrophotometric assay. The best results regarding plant regeneration and solasodine accumulation were obtained by using the MS basal medium without addition of plant growth regulators; however, there was great production of calluses presenting friable bases. Based on these results, cell cultures can be initiated from such calluses with application of other auxins and cytokinins to enhance solasodine production, besides different elicitors, light intensities and sucrose concentrations.A regeneração de Solanum torvum e a avaliação do conteúdo de solasodina foram os objetivos de cultura de segmentos nodais. A influência de auxinas (ácido 3-indolacético, ácido naftalenoacético e de 6-benzilaminopurina no crescimento de S. torvum na micropropagação foi investigado. Cultura de segmentos nodais foi iniciada por sementes germinadas em meio básico MS acrescido de GA3 e cultivadas em diferentes concentrações de AIA, AIA + BAP e ANA + BAP. Plantas da cultura in vitro com 60 dias foram coletadas, congeladas e liofilizadas e o método de alaranjado de metila foi utilizado para quantificação de solasodina para o ensaio espectrofotométrico. Os melhores resultados para regeneração vegetal e acúmulo de solasodina foram alcançados no meio MS sem adição de reguladores de crescimento havendo, porém grande produção de calos de base friáveis.

    Background Interferon-induced transmembrane protein 1 (IFITM1) has been identified as a molecular marker of the colorectal tumors; however its influences on the biological behaviors of the colorectal cancer cells are currently unknown.We aimed to study the influences of IFITM1 on the proliferation,invasion,and metastasis of the colorectal cancer SW480 cell lines.Methods We constructed IFITM1/pEGFP-C3 recombinant plasmids and transfected them into the colorectal cancer SW480 cell lines.IFITM1/pEGFP-C3 recombinant plasmids were identified by means of immunofluorescence,laser confocal scanning microscopy,and reverse transcription polymerase chain reaction.IFITM1/SW480 cells with stable over-expression of IFITM1 were confirmed by G418 screening.The influences of IFITM1 on the proliferation of the SW480 cell lines were investigated by MTT assay and tumor transplantation experiments in nude mice.Cell invasion experiments were performed to determine the invasion capacity of the IFITM1/SW480 cells.Matrix metalloproteinase 2 (MMP-2) and MMP-9 activities were detected by the gelatin zymographic analysis,and MMP-9 expression by the Western blotting analysis.Results IFITM1/pEGFP-C3 recombinant plasmids were successfully constructed in this study,and the IFITM1/SW480 cells with stable IFITM1 gene over-expression were confirmed by G418 screening.MTT results showed that the proliferation of the IFITM1/SW480 cells was significantly enhanced (P <0.01).Tumors were harvested from four weeks old mice.Tumor volumes were (1347.00±60.94) mm3,(1032.40±111.38) mm3 and (1018.78±28.83) mm3; and tumor weights were (1522.34±62.76) mg,(1137.78±97.22) mg and (1155.76±133.31) mg for mice inoculated with the IFITM1/SW480 cells,pEGFP-C3/SW480 cells and SW480 cells,respectively.Tumor volumes and weights from mice inoculated with the IFITM1/SW480 cells were significantly increased (P <0.01).In addition,the numbers of the SW480 cells and IFITM1/SW480 cells that migrated through Matrigel were

    Tissue factor (TF)/VIIa/protease‑activated receptor 2 (PAR2) has been shown to trigger the ERK1/2 signaling pathway. This was shown to be closely associated with the proliferation and migration of SW620 colon cancer cells; however, the detailed mechanisms remain unclear. The aim of the present study was to elucidate the effects of calcium signaling on the proliferation and migration of SW620 cells induced by coagulation factor VIIa. The results demonstrated that VIIa and PAR2 agonist PAR2‑AP increased [Ca2+]i in SW620 cells. In addition, VIIa‑and PAR2‑AP‑induced ERK1/2 activation was inhibited by thapsigargin (TG)‑induced depletion of intracellular Ca2+ stores and EGTA‑mediated removal of extracellular Ca2+. It was also identified that VIIa and PAR2‑AP‑induced proliferation and migration of SW620 cells was modulated by EGTA and TG. Taken together, the present results indicate that VIIa triggers calcium signaling in SW620 cells, in a TF‑dependent manner, which is critical for VIIa‑induced ERK1/2 activation in SW620 cells. These results suggested that calcium signaling had a vital role in the proliferation and migration of SW620 cells.

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

    The Corinth Rift, one of the most active rifts in the world as local extension trending NE-SW reaches the amount of 14±2 mm/yr, corresponds to one of the largest zones of seismically active normal faulting. The formation, growth and migration southwards of the prevailing fault systems, which evolve simultaneously with the intense morphogenetic processes, are overprinted in the age, facies and thickness of the Plio-Pleistocene sequences constructing the south margin of the western Gulf of Corinth. The dominant fault blocks, defined by east-west trending, north dipping normal faults, are accompanied by several morphological features and anomalies, noticed in both the terrestrial and the marine environment. Our main aim has been to examine how the tectonic evolution, in combination with the attendant fierce erosional and sedimentary processes, has affected the morphology through geodynamic processes expressed as failures in the wider coastal area. High resolution multibeam bathymetry in combination with the available land surface data have contributed to submarine and subaerial morphological mapping. These have been used as a basis for the detection of all those geomorphic features that indicate instabilities probably triggered, directly or indirectly, by the ongoing active tectonic deformation. The interpretation of the combined datasets shows that the southwestern margin of the Corinth Rift towards Psathopyrgos fault zone is characterized by intense coastal relief and a narrow, almost absent, continental shelf, which passes abruptly to steep submarine slopes. These steep slope values denote the effects of the most recent brittle deformation and are related to coastal and submarine instabilities and failures. High uplift rates and rapid sedimentation, indicative of the regional high-energy terrestrial and submarine environment, are subsequently balanced by the transportation of the seafloor currents, especially where slope gradients decrease, disintegrating the

    Eighty four new U-Th ages are presented for twenty randomly selected broken, displaced and reworked calcite speleothems retrieved from clastic sedimentary fill and from isolated bedding-plane shelves in Crag cave (SW Ireland). The dated pre-Holocene samples span much of the last glacial, ranging in age from 85.15 ± 0.60 to 23.45 ± 0.17 ka. Speleothem deposition requires the presence of liquid water, and because Crag cave is a shallow system, deposition is considered likely only when mean annual air temperatures (MAAT) exceed the freezing point of water. Deposition at this mid-latitude ocean-marginal site occurred episodically during MIS5a through to MIS2, synchronously within dating uncertainties, with the timing of Greenland Interstadials (GI). In the latter part of Marine Isotope Stage 3 (MIS3), deposition was particularly intense, consistent with regional scale climate amelioration inferred previously from radiocarbon ages for sparse MIS3 organic and freshwater surficial deposits in N. Ireland. A brief episode of speleothem deposition at c.23.40 ± 0.22 ka coincides with GI-2, demonstrating the sensitivity of the site to brief climate amelioration episodes in Greenland during MIS2. Conditions favourable for speleothem deposition occurred periodically during the last glacial, indicating temperature changes of at least 10 °C between stadials and interstadials at this mid-latitude site. Deposition ceased during Greenland Stadials (GS), including during periods of ice-rafting in the adjacent N. Atlantic Ocean (Heinrich events). Oxygen and carbon isotope ratios of the last glacial speleothems are generally elevated, reflecting non-equilibrium isotope fractionation effects. However, establishment of low δ13C values often occurred within a few decades of climate amelioration, indicating that biogenic CO2 production resumed rapidly at this site, particularly during MIS3. Speleothem δ18O variability was driven largely by long-term changes in the δ18O value of the

    Mineralogical studies of the Karkonosze granite (ca. 322-312 Ma) and its surroundings in West Sudetes (SW Poland) have provided data on Nb-Ta-REE minerals from pegmatites in the NE part of the pluton and several new finds of Ag minerals and 15 oxygenic Bi phases, hitherto not reported from the massif. The Karkonosze pegmatites are enriched in HREE as fergusonite-(Y) or xenotime-(Y) appear in almost every studied pegmatite, together with a subordinate assemblage of the aeschynite, euxenite or columbite group. The abundance of LREE minerals such as allanite-( Ce) and the monazite group, correlates inversely with the Nb-Ta-Ti minerals, whilst an early generation of monazite-(Ce) revealed an exceptionally high amount of Nd (up to 22 wt.% of Nd2O3 ). The physical and chemical conditions during the magmatic and post-magmatic processes were reconstructed and the effects of contact metamorphism in amphibolites from hornfelsed zones examined. Changes in solution composition and concentration at the early magmatic stage (825-920°C), pegmatitic stage overlapping with hydrothermal (560°C which ended at 160-90°C) and clearly hydrothermal stage (400 to 110°C) were studied in detail by means of melt and fluid inclusions in quartz. Furthermore, post-magmatic fluids, including some enriched in Li and B, were identified in rock-forming quartz from the whole pluton. In turn, study of the amphibolites indicates that the pair cummingtonite + anorthite or the presence of Ca-rich plagioclase with actinolite seem to be reliable mineral proxies of the thermal impact of the granitoid body on amphibolites in its envelope. The inferred conditions of the contact processes (450-550°C, 2.5- 4.8 kbar) point to an elevated geothermal gradient (ca. 32-45°C/km) probably reflecting the heat flow induced by the Karkonosze intrusion. Moreover, despite the textural and mineral changes imposed by regional and contact metamorphism, the amphibolites have their pre-metamorphic (magmatic) geochemical

    We present a new classification of geological (basement) domains at the Africa-Eurasia plate boundary offshore SW Iberia, together with a regional geodynamic reconstruction spanning from the Mesozoic extension to the Neogene-to-present-day convergence. It is based on seismic velocity and density models along two regional wide-angle seismic transects, one running NW-SE from the Tagus to the Seine abyssal plains, and the other running N-S from S Portugal to the Seine Abyssal Plain, combined with previously available information. The seismic velocity and density structure at the Seine Abyssal Plain and the internal Gulf of Cadiz indicates the presence of a highly heterogeneous oceanic crust, similar to that described in ultra-slow spreading centers, whereas in the Horseshoe and Tagus abyssal plains, the basement structure resembles that of exhumed mantle sections identified in the Northern Atlantic margin. The integration of all this new information allows defining the presence of three oceanic domains off SW Iberia: (1) the Seine Abyssal Plain domain, generated during the first stages of slow seafloor spreading in the NE segment of the Central Atlantic (Early Jurassic); (2) the Gulf of Cadiz domain, made of oceanic crust generated in the Alpine-Tethys spreading system between Iberia and Africa, which was coeval with the formation of the Seine Abyssal Plain domain and lasted up to the North Atlantic continental break-up (Late Jurassic); and (3) the Gorringe Bank domain, mainly made of rocks exhumed from the mantle with little synchronous magmatism, which formed during the first stages of North Atlantic opening (Early Cretaceous). Our models suggest that the Seine Abyssal Plain and Gulf of Cadiz domains are separated by the Lineament South strike-slip fault, whereas the Gulf of Cadiz and Gorringe Bank domains appear to be limited by a deep thrust fault located at the center of the Horseshoe Abyssal Plain, which coincides with the seismicity cluster nucleated in the

    Mafic dikes and sills intruded the sedimentary succession in the Orito Oil Field, located in the Putumayo Basin, SW Colombia. One sample from the Orito-4 well yields a Late Miocene to Pliocene age (40K/40Ar on amphibole 6.1 ± 0.7 Ma) for the igneous event in the basin. This coincides with the widely recognized regional Andean orogenic uplift that affected most of sub-Andean Peru, Ecuador, and Colombia. Furthermore, the uplift consequently coincides with a second pulse of hydrocarbon generation and expulsion in the Putumayo Basin. This second pulse was thermally more evolved than the first one (Late Oligocene - Miocene). The high content of CO2 in the gas budget recovered in different wells along the basin may be related to the heat flux of the mafic intrusions. There are four geological events that coincide with this large scale evolution during the late Miocene to early Pliocene (13 - 3 Ma): regional orogenic uplift, persistent igneous intrusions, CO2 formation, and a second pulse of hydrocarbon generation and expulsion. The Late Miocene - Pliocene age of the intrusion is the key to formulate a hypothesis where these four events are joined together. Regional uplift and intrusions: The mafic rocks of the Orito Oil Field show Sr-Nd-Pb isotopic compositions that suggest derivation from a mantle source below the western edge of the South American continent. The geochemical signature of these rocks that form part of the Northern Volcanic Zone (NVZ) reflects subduction-related magmatism. Thus, they record subduction and start of the last pervasive uplift episode that took place during the Late Neogene. Intrusions and second migration phase: The Late Miocene pulse of hydrocarbon generation and migration coincides closely with the estimated age of the intrusions; therefore, a causal link with the geothermal anomaly induced by the mafic igneous rocks is likely. The temperature of a mafic magma reaching 1000 to 1200°C is sufficient to heat the host rocks, where the

    The South China Sea (SCS) is the largest marginal basin in SE Asia and exhibits hundreds of kilometres of extended continental crust on both conjugate margins. The structures and processes leading to the formation of the SCS are still debated at various levels (timing, mechanisms). A joint collaboration between French and Chinese scientists led to the acquisition of coincident refraction and reflection seismic data over the SW sub-basin. In 2011, a 1000-km-long refraction line was first shot using R/V Tan Bao and 50 Ocean Bottom Seismometers (OBS). Among the results was the homogeneous thickness (~12 km) of the thinned continental crust over hundreds of kilometres and the possible large scale normal faults rooting in a ductile lower crust which could explain the relatively flat Moho. The coincident multichannel seismic (MCS) profile is now available to us. The 1000-km-long MCS line was acquired using a ~7000 cu.in. tuned airgun array and 6 to 8 km long streamers. Here we focus on a 230-km-long section of the profile to the south of the V-shaped SW oceanic basin across Spratley Islands. Multiples attenuation and high density velocity analysis are performed to obtain a detailed imaging of the sediments and crust at depth. We apply pre-stack Kirchhoff time migration and superimpose the obtained reflectivity on the refraction velocity model. The processed section includes a basin bound by a large crustal normal fault already imaged in the refraction velocity model, although no information on the basement was used to model the refraction velocities. The results validate the interpretation of the refraction velocity lateral variations and emphasize the significant vertical offsets of the large scale normal faults. Deep crustal reflectivity may give additional hints at a lower crustal ductile flow. Future work will consist in using the geometry of the MCS profiles in the refraction velocity modelling and an attempt to use more advanced migration methods with the help of

    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.

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,
