Pollen ages and depths in ODP Site 184-1144

A high-resolution pollen record (sampling interval averages 820 years) has been obtained from ODP Site 1144 (water depth 2037 m), northern South China Sea. The 504-m sequence (in composition length) covers the last 1.03 million years according to micropaleontological and isotopic stratigraphy. The pollen assemblages are characterized by high proportions of Pinus and herb pollen, and by their frequent alternations. Based on these alternations, 29 pollen zones have been recognized that are closely correlated to the Marine Oxygen Isotope Stages (MIS) 1-29. Pinus- dominant pollen zones correspond to interglacial periods with lighter delta18O values, while herb-marked ones relate to the heavier delta18O stages assigned to glacials. Judging from the pollen data, the exposed northern continental shelf of the South China Sea during the glacials was covered by grassland, and the extensive northern shelf has formed only since MIS 6 (ca. 150 ka), probably as a result of tectonic subsidence. Tree pollen influx values are indicative of winter monsoon which began to intensify 600 ka ago. The summer monsoon variations can be approximated by the fern percentage within the total pollen and spore abundance, and the result shows high values in general occurring at interglacials, with the maxima at MIS 15, 5e and 1. The relatively high fern percentage with smaller amplitude in variations before 600 ka might suggest more stable humid conditions before the intensification of winter monsoon.

Late Holocene pollen and organic walled dinoflagellate cysts analyses of sedimet cores from the Java Sea

The pollen, spore and organic walled dinoflagelletas cyst associations of two marine sediment cores from the Java Sea off the mouths of Jelai River (South Kalimantan) and Solo River (East Java) reflect environment and vegetation changes during the last ca 3500 years in the region. A decline in primary forest taxa (e.g. Agathis, Allophylus, Dacrycarpus, Dacrydium, Dipterocarpaceae, Phyllocladus, and Podocarpus) suggest that the major change in vegetation is caused by the forest canopy opening that can be related to human activity. The successively increase of pollen of pioneer canopy and herb taxa (e.g. Acalypha, Ficus, Macaranga/Mallotus, Trema, Pandanus) indicate the development of a secondary vegetation. In Java these changes started much earlier (ca at 2950 cal yr BP) then in Kalimantan (ca at 910 cal yr BP) and seem to be more severe. Changes in the marine realm, reflected by the dinoflagellate cyst association correspond to changes in vegetation on land. They reflect a gradual change from relatively well ventilated to more hypoxic bottom/pore water conditions in a more eutrophic environment. Near the coast of Java, the shift of the water trophic status took place between ca 820 and 500 cal yrs BP, while near the coast of Kalimantan it occurred as late as at the beginning of the 20th century. We observe an increasing amount of the cyst of Polykrikos schwarzii, cyst of P. kofoidii, Lingulodinium machaerophorum, Nematosphaeropsis labyrinthus and Selenopemphix nephroides at times of secondary vegetation development on land, suggesting that these species react strongly on human induced changes in the marine environment, probably related to increased pollution and eutrophication.

Vegetation cover and radiocarbon dates of palsa and peat plateaus in the Hudson Bay Lowlands

The Holocene development of a treed palsa bog and a peat plateau bog, located near the railroad to Churchill in the Hudson Bay Lowlands of northeastern Manitoba, was traced using peat macrofossil and radiocarbon analyses. Both sites first developed as wet rich fens through paludification of forested uplands around 6800 cal. yr BP. Results show a 20th-century age for the palsa formation and repeated periods of permafrost aggradation and collapse at the peat plateau site during the late Holocene. This timing of permafrost dynamics corroborates well with that inferred from previous studies on other permafrost peatlands in the same region. The developmental history of the palsa and peat plateau bogs is similar to that of adjacent permafrost-free fens, except for the specific frost heave and collapse features associated with permafrost dynamics. Permafrost aggradation and degradation is ascribed to regional climatic, local autogenic and other factors. Particularly the very recent palsa development can be assessed in terms of climatic changes as inferred from meteorological data and surface hydrological changes related to construction of the railroad. The results indicate that cold years with limited snowfall as well as altered drainage patterns associated with infrastructure development may have contributed to the recent palsa formation.

A taste of the technical cuisine: metals and other ingredients

According to cognitive linguistics, language has an experiential origin based on perception, sensory motor activities and our knowledge of the world. Our thought operates by establishing similarities, links and associations that enable us to talk about one thing in terms of another as shown in the example of love as a journey (Lakoff and Johnson, 1980). Metaphor and metonymy are conceptual and linguistic tools that make possible most of these cognitive operations. Since metaphor is an essential element of human communication, the discourse of specialised disciplines includes metaphorical mappings and numerous examples of metaphorical expressions, for example in economics, where business is mapped in terms of war (White, 2004; Herrera & White, 2000), electrotechnics with electrical components understood as couples (Roldán- Riejos in preparation) or in civil engineering where a bridge is conceptualized as a person (Roldán-Riejos, 2013). In this paper, the metaphors: WORKING WITH METALS IS COOKING/ TRABAJAR CON METALES ES COCINAR and METALS ARE CULINARY OBJECTS/ LOS METALES SON OBJETOS CULINARIOS are explored. The main aim is to show that the cooking metaphor is widely spread in the metallurgical domain in English and Spanish, although with different nuances in each language due to socio-cultural factors. The method adopted consists of analysing examples taken from the: Bilingual Dictionary of Scientific and Technical Metaphors and Metonymies Spanish- English/English-Spanish, a forthcoming and rigorously documented bilingual dictionary that sums up research on conceptual, linguistic and visual metaphor and metonymy in different areas of engineering (Roldán-Riejos and Molina, 2013). The present paper studies in detail English and Spanish cross-linguistic correspondences related to types of metals and processes. It is suggested that they reflect synesthetic metaphoric mappings. The exploitation of cognitive conceptual metaphor in the ESP classroom is lastly recommended.

Q/R site editing in kainate receptor GluR5 and GluR6 pre-mRNAs requires distant intronic sequences.

RNA editing by adenosine deamination in brain-expressed pre-mRNAs for glutamate receptor (GluR) subunits alters gene-specified codons for functionally critical positions, such as the channel's Q/R site. We show by transcript analysis of minigenes transiently expressed in PC-12 cells that, in contrast to GluR-B pre-mRNA, where the two editing sites (Q/R and R/G) require base pairing with nearby intronic editing site complementary sequences (ECSs), editing in GluR5 and GluR6 pre-mRNAs recruits an ECS located as far as 1900 nucleotides distal to the Q/R site. The exon-intron duplex structure of the GluR5 and GluR6 pre-mRNAs appears to be a substrate of double-stranded RNA-specific adenosine deaminase. This enzyme when coexpressed in HEK 293 cells preferentially targets the adenosine of the Q/R site and of an unpaired position in the ECS which is highly edited in brain.

La gastronomía como Industria Creativa en un contexto digital. Análisis de webs y redes sociales de los restaurantes españoles con estrella Michelin

En los últimos años es evidente el éxito creciente de la gastronomía, no sólo como mercado económico sino también desde una perspectiva comunicativa. Entendida como una Industria Creativa, la gastronomía está adquiriendo cada vez más peso en el mercado de la comunicación y se están desarrollando planes estratégicos que acercan progresivamente el sector gastronómico a todos los públicos, democratizando el arte de la cocina y haciendo de éste un talento accesible y disponible para todos los públicos. En pleno contexto de crecimiento, las estrategias y recursos comunicativos que utilizan tanto los mass media como los propios restaurantes y profesionales de la cocina, se han de convertir en objeto de estudio necesario para entender, por ejemplo, de qué manera se explotan los recursos comunicacionales y cuál es el alcance de los mismos así como sus oportunidades. El presente artículo se centra en un análisis de contenido de las páginas webs y las redes sociales utilizadas por los ocho restaurantes españoles galardonados con tres estrellas por la Guía Michelin España-Portugal (2014), sometidos a estudio en la misma semana (del 15 al 21 de septiembre). El objetivo principal es tratar de conocer estrategia de comunicación online llevada a cabo por estos restaurantes y establecer la importancia que se les atribuye a los recursos web a la hora de contribuir tanto a la consolidación de sus propias marcas como a la propia Industria Creativa gastronómica. Los resultados muestran cierta disparidad en el uso tanto de los recursos web como de los social media y avanzan que el sector gastronómico y de la restauración española tiene un reto: seguir comunicando implicándose en mayor medida con la bidireccionalidad e invitación a la participación de sus públicos, con el objetivo de captar nuevos contactos, fidelizar a los clientes actuales y convertir a todos ellos en prescriptores de sus servicios.

Pollen record and age determiation of sediments from the Labaz Lake area

Pollen records from perennially frozen sequences provide vegetation and climate reconstruction for the last 48,000 14C years in the central part of Taymyr Peninsula. Open larch forest with Alnus fruticosa and Betula nana grew during the Kargin (Middle Weichselian) Interstade, ca. 48,000-25,000 14C yr B.P. The climate was generally warmer and wetter than today. Open steppe-like communities with Artemisia, Poaceae, Asteraceae, and herb tundralike communities with dwarf Betula and Salix dominated during the Sartan (Late Weichselian) Stade, ca. 24,000-10,300 14C yr B.P. The statistical information method used for climate reconstruction shows that the coldest climate was ca. 20,000-17,000 14C yr B.P. A warming (Allerød Interstade?) with mean July temperature ca. 1.5°C warmer than today occurred ca. 12,000 14C yr B.P. The following cooling with temperatures about 3°-4°C cooler than present and precipitation about 100 mm lower corresponds well with the Younger Dryas Stade. Tundra-steppe vegetation changed to Betula nana-Alnus fruticosa shrub tundra ca. 10,000 14C yr B.P. Larch appeared in the area ca. 9400 14C yr B.P. and disappeared after 2900 14C yr B.P. Cooling events ca. 10,500, 9600, and 8200 14C yr B.P. characterized the first half of the Holocene. A significant warming occurred ca. 8500 14C yr B.P., but the Holocene temperature maximum was at about 6000-4500 14C yr B.P. The vegetation cover approximated modern conditions ca. 2800 14C yr B.P. Late Holocene warming events occurred at ca. 3500, 2000, and 1000 14C yr B.P. A cooling (Little Ice Age?) took place between 500 and 200 14C yr ago.

Relative abundances of planktonic foraminifera from surface sediments of the Drake Passage, Southern Ocean (Table 1)

Based on a qualitative and quantitative evaluation of Recent sediments samples (top 3 cm of cores as well as Petersen grab samples) from the Drake Passage, between South America and Antarctica, the distribution of planktonic foraminifera and their relation to oceanographic conditions was investigated. The Antarctic Convergence - the northern limit of the cold Antarctic Surface Water - is shown to be of major importance in controlling the distributional pattern of planktonic species as well as their total numbers. South of the convergence, Globigerina pachyderma is usually the only species found in the sediment. It occurs with abundances not greater than 6000 per gram dry sediment, and at most stations less than 100 specimens per gram of dry sediment were recovered. At a number of deep-sea stations below 3700 m depth approx. no planktonic foraminifera were found at all. It is most probable, that at least some of these stations are located below the limit of CaCO3 dissolution. North of the Antarctic Convergence planktonic foraminiferal numbers are much higher and range from 1800 to 120000 per gram of dry sediment. Eight species are the major constituents of the population: Globigerina pachyderma, Globigerina bulloides, Globogerina quinqueloba, Globigerina inflata, Globorotalia truncatolinoides, Globorotalia scitula, Globigerinita glutinata and Globigerinita uvula. The widespread occurrence of Globorotalia truncatulinoides, which in the northern hemisphere is usually a subtropical form, is especially noteworthy. Another Globigerina, morphologically similar to G. pachyderma, has been recognized frequently north of the Antarctic Convergence. Globigerina megastoma which has its type area in the Drake Passage, has been found only rarely. Orbulina universa occurs in samples from the areas of higher water temperature around the South American Continent. Globigerina pachyderma is predominantly sinistrally coiled throughout the area investigated, but a slight increase in the percentage of dextrally coiled specimens may be noticed with increasing water temperature, i.e. from south to north.
