Quantitative micrograph, HPLC and FTIR profiles of Melissa officinalis and Nepeta cataria (Lamiaceae) from Argentina

Melissa officinalis L., so called "Melissa" or "Toronjil", is a perennial aromatic herb, whose leaves are used in traditional medicine as a carminative, digestive and sedative, both in simple as in mixtures. Meanwhile, Nepeta cataria L., commonly called "Cat mint" or "Toronjil", with some similar properties, often replacing M. officinalis in the market, although their chemical composition is not completely matched, and contains an iridoid potentially toxic (nepetalactone). It is therefore necessary to establish diacritic parameters to differentiate these species, both at crude drug level, mixtures and extracts. Samples from various sources in Argentina were studied and documental specimens are preserved in the Herbarium UNSL. Anatomical sections were analyzed, and quantitative micrographic parameters were obtained, together with HPLC and FTIR spectra from methanolic and aqueous lyophilized extracts. Significant differences were detected in the prevailing smell foliage, morphology of leaves and inflorescences, trichomata type, palisade ratio, veinlet termination number, rosmarinic acid concentration (with distinctive HPLC profiles), and the CO/CH relationships obtained by FTIR from the extracts, that together allow adequate differentiation of both drugs, even when they were ground or powdered.

Pollen profiles from 8 sediment cores from the Degersee, Southern Germany

The discovery of a neolithic pile field in the shallow water near the eastern shore of the Degersee confirmed earlier palynological and sedimentological studies stating that early man was active in the region since more than 6000 years. The already available off-site data were freshly assessed, completed by additional data from old and new cores and the interpretations revised. A common time scale for the off-site data and the on-site data was obtained by AMS dating of terrestrial macro remains of the neolithic section of off-site core De_I+De_H. The ages can thus be parallelled with AMS ages of construction timber on-site. Pollen analyses from all cores provide a further time scale. The continuously and densely sampled pollen profile of the profundal zone embracing the entire Late glacial and Holocene serves as a reference. From the Boreal onwards the relative ages are transformed by AMS ages and varve counts into calibrated and absolute. A transect cored close to the neolithic pile field across the lake marl-platform demonstrates its geological architecture in the shallow water since the Lateglacial. Studies of the microfabric of thin sections of drilled cores and of box cores from the excavations demonstrate that neolithic settlements now at 2-3,5 m water depth had been erected on lake marl freshly fallen dry, thus indicating earlier lake levels dropped by 1.5-2 m. The neolithic section of the highly resolved off-site profile in the lake=s profundal zone has laminated and calcareous zones alternating with massive ones. Assemblages of diatoms and concentrations of trace elements changing simultaneously characterise the calcareous sections as deposits of low lake levels that lasted between some 40 and more than 300 years. The ages of discovered lake shore dwellings fall into calcareous segments with low lake levels. From the end of the Upper Atlantic period (F VII) appear Secondary Forest Cycles in the beech forest, a man-made sequence of repeated vegetational development with an identical pattern: With a decrease of beech pollen appear pollen of grasses, herbs and cultural indicators. These are suppressed by the light demanding hazel and birch, those again by ash, and finally by the shade demanding beech forming a new pollen peak. Seven main Forest Cycles are identified In the upper Neolithic period each comprising some 250, 450 or 800 years. They are subdivided into subcycles that can be broken down by very dense sampling in even shorter cycles of decadal length. Farming settlers have caused minor patchy clearances of the beech-mixed-forest with the use of fire. The phases of clearance coincide with peaks of charcoal and low stands of the lake levels. The Secondary Forest Cycles and the continuous occurrence of charcoal prove a continued occupation of the region. Together with the repeated restoration of the beech climax forest they point to pulsating occupation probably associated with dynamic demography. The synchronism of the many palynological, sedimentological and archaeological data point to an external forcing as the climate that affects comprehensively all these proxies. The fluctuations of the activity of the sun as manifested in the residual d14C go largely along with the proxies. The initial clearances at the begin of the forest cycles are linked to low lake levels and negative values of d14C that point to dry and warm phases of a more continental climate type. The subcycles exist independent from climatic changes, indicating that early man acted largely independent from external forces.

High-resolution multi-proxy record of the last glacial period from Lake Van, eastern Anatolian high plateau, Turkey

Detailed analyses of the Lake Van pollen, Ca/K ratio and stable oxygen isotope record allow the identification of millennial-scale vegetation and environmental changes in eastern Anatolia throughout the last glacial (~75-15 ka BP). The climate within the last glacial was cold and dry, with low arboreal pollen (AP) levels. The driest and coldest period corresponds to Marine Isotope Stage (MIS) 2 (~28-14.5 ka BP) dominated by the highest values of xerophytic steppe vegetation. Our high-resolution multi proxy record shows rapid expansions and contractions of tree populations that reflects variability in temperature and moisture availability. This rapid vegetation and environmental changes can be linked to the stadial-interstadial pattern of the Dansgaard-Oeschger (DO) events as recorded in the Greenland ice cores. Periods of reduced moisture availability were characterized by enhanced xerophytic species and high terrigenous input from the Lake Van catchment area. Furthermore, comparison with the marine realm reveals that the complex atmosphere-ocean interaction can be explained by the strength and position of the westerlies, which is responsible for the supply of humidity in eastern Anatolia. Influenced by diverse topography of the Lake Van catchment, larger DO interstadials (e.g. DO 19, 17-16, 14, 12 and 8) show the highest expansion of temperate species within the last glacial. However, Heinrich events (HE), characterized by highest concentrations of ice-rafted debris (IRD) in marine sediments, are identified in eastern Anatolia by AP values not lower and high steppe components not more abundant than during DO stadials. In addition, this work is a first attempt to establish a continuous microscopic charcoal record over the last glacial in the Near East, which documents an initial immediate response to millennial-scale climate and environmental variability and enables us to shed light on the history of fire activity during the last glacial.

High-resolution multi-proxy record of the last interglacial period from Lake Van, eastern Anatolian high plateau, Turkey

A high-resolution multi-proxy record from Lake Van, eastern Anatolia, derived from a lacustrine sequence cored at the 357 m deep Ahlat Ridge (AR), allows a comprehensive view of paleoclimate and environmental history in the continental Near East during the last interglacial (LI). We combined paleovegetation (pollen), stable oxygen isotope (d18Obulk) and XRF data from the same sedimentary sequence, showing distinct variations during the period from 135 to 110 ka ago leading into and out of full interglacial conditions. The last interglacial plateau, as defined by the presence of thermophilous steppe-forest communities, lasted ca. 13.5 ka, from ~129.1-115.6 ka BP. The detailed palynological sequence at Lake Van documents a vegetation succession with several climatic phases: (I) the Pistacia zone (ca. 131.2-129.1 ka BP) indicates summer dryness and mild winter conditions during the initial warming, (II) the Quercus-Ulmus zone (ca. 129.1-127.2 ka BP) occurred during warm and humid climate conditions with enhanced evaporation, (III) the Carpinus zone (ca. 127.2-124.1 ka BP) suggest increasingly cooler and wetter conditions, and (IV) the expansion of Pinus at ~124.1 ka BP marks the onset of a colder/drier environment that extended into the interval of global ice growth. Pollen data suggest migration of thermophilous trees from refugial areas at the beginning of the last interglacial. Analogous to the current interglacial, the migration documents a time lag between the onset of climatic amelioration and the establishment of an oak steppe-forest, spanning 2.1 ka. Hence, the major difference between the last interglacial compared to the current interglacial (Holocene) is the abundance of Pinus as well as the decrease of deciduous broad-leaved trees, indicating higher continentality during the last interglacial. Finally, our results demonstrate intra-interglacial variability in the low mid-latitudes and suggest a close connection with the high-frequency climate variability recorded in Greenland ice cores.

Escribir las periferias : Representaciones literarias de la segregación urbana en Las Colinas del Hambre de Rosa Wernicke

En esta comunicación se rastrean las formas literarias de la representación de la ciudad en el período de expansión de Rosario y durante la entreguerras. A través de la novela de Rosa Wernicke, se estudian las imágenes literarias de Rosario a comienzos de los años 1940s. Entre 1887 y 1926, los censos de municipales retratan un crecimiento vertiginoso de la ciudad y su literatura confirma la estabilización de sus cualidades modernas. Sin embargo, esas representaciones de lo urbano ignoraban los costados menos autocomplacientes del progreso. La literatura de Wernicke nos permite explorar las periferias de una ciudad que se imaginaba a sí misma como homogéneamente moderna y carente de bordes y contradicciones

Tiempo y espacio en la novela Azul de Rosa Regàs

La novela Azul de Rosa Regàs contiene la relación de una historia sentimental de diez años que no se desarrolla linealmente, sino que se articula en una estructura de "tiempo reducido retrospectivo". El tiempo reducido abarca tres días. Un percance obliga a los viajeros del barco "Albatros" a cambiar el itinerario y detenerse en el puerto más cercano, en una pequeña isla. El texto entrelaza las dos historias: la de tres días correspondiente al nivel primario y la de diez años correspondiente al nivel secundario. La técnica de intercalar los fragmentos de cada nivel requiere el análisis de los recursos con que un relato aparece insertado en el otro. Los conflictos de la pareja central, en especial el del protagonista, dan lugar a diversas consideraciones sobre el tiempo: su pasar desgastante, los cambios en la persona y en el plano sociohistórico, y el contraste entre el tiempo subjetivo y el objetivo. En cuanto al espacio, la isla es el escenario propicio para la soledad en la que el joven protagonista vivirá experiencias comparables a una catábasis, a una revelación sobre sí mismo. Los efectos no son inmediatos ni decisivos. Martín Ures es introvertido, inseguro: varios factores lo ponen en desventaja frente a su entorno, pero el texto se concentra en señalar como factor definitorio su origen geográfico, es "hombre de tierra adentro". No se separa de su esposa. Para seguir juntos han tenido que recurrir al olvido y someterse a la ley universal del dolor. Por eso la novela que comienza hablando de la isla termina con una palabra que ensancha ampliamente la dimensión espacial y que en el contexto no está exenta de implicaciones temporales: ambos están inmersos en "el marasmo de dolor del mundo".

El columnismo literario de Rosa Regás y de Rosa Montero : Discurso neomoderno y construcción de imagen

Tomando como punto de partida las consideraciones vigentes acerca de los resultados sociales y literarios del proceso de globalización acelerada que experimentó España a lo largo de las décadas posteriores a la transición democrática, este trabajo se propone realizar una confrontación entre el discurso de la crítica literaria y del pensamiento filosófico, en muchos casos poco favorable, en torno a las características de la lectura y el consumo de bienes culturales en el periodo mencionado y la construcción de la imagen de escritora que llevan a cabo Rosa Regás y Rosa Montero en su labor de columnistas en los periódicos El Correo y El País, respectivamente. El análisis pretende vincular conceptos de la teoría de género, específicamente provenientes del desarrollo del feminismo ilustrado, cuyos postulados es posible rastrear de modo no necesariamente consciente en las decisiones temáticas e ideológicas de las escritoras mencionadas; con consideraciones relativas al debate acerca del estatuto literario de la columna de opinión. En este punto, se tendrán en consideración las características dominantes del estado de la novela en el campo literario español hacia la década del 90 específicamente como trasfondo discursivo del que la práctica periodístico literaria surge (teniendo en cuenta que la narrativa de Montero y de Regás se desarrolla preferentemente dentro del género novela) y en el que surgen una construcción de sujeto y un modo de vincularse con la materia real que pueden describirse como relativos a un discurso superador de la vertiente rupturista posmoderna
