Abstract: Dendritic cells (DCs) play crucial roles in initiating and promoting immune defences, providing a pivotal target for vaccines. Although nanoparticle/nanogel-based delivery vehicles are showing potential for delivering vaccines to the immune system, there is little information on their characteristics of interaction with DCs. While particle uptake by DCs has been shown, the mechanism of cell targeting has not been studied. Moreover, it is still unclear how particle surface decoration influences the handling of such vaccines by DCs. Accordingly, chitosan nanogels carrying a model antigen, ovalbumin (ova), were analysed for interaction with and processing by DCs. Nanogel surfaces decorated with alginate (alg) or mannosylated alginate (alg-man), were used for targeting particular DC receptors. DC uptake of particles was observed, being dependent on endosomal-based processes. Inhibiting PI3-kinase or lipid raft activities impaired the uptake, which was only reduced, indicating the involvement of more than one endocytic pathway; notably, this was observed with both nanogel-delivered or free ova. Importantly, surface decoration of particles was less influential on particle uptake, contrasting with the ova cargo which played the major role. Such influence of the vaccine cargo has to date been largely ignored. When receptors interacting directly with ova were blocked, this altered the uptake of alg-nanogels and alg-man-nanogels carrying ova. The nanogels did have an influential role, in that modulation of DC functional activity owed more to the nanogel structure. Using an in vitro restimulation assay with ova-specific lymphocytes, nanogel-delivered and free ova were similarly effective at inducing specific antibody. Nanogel-delivered ova with mannose surface decoration was superior to free ova for inducing interferon-γ production by T-lymphocytes. Together, the data demonstrates that particle-based vaccine delivery should consider the influences of both the surface decoration and the vaccine cargo; each can influence different aspects of the interaction with DCs. Such combined influences are likely to impinge on the characteristics of the immune response induced.

154. Toothbrushing procedure in schoolchildren with no previous formal instruction: variables associated to dental biofilm removal

Author: Glenda N, Rossi, Ana L, Sorazabal, Pablo A, Salgado, Aldo F, Squassi, and Graciela L, Klemonskis
Subjects: Toothbrushing, Biofilms, Dental Plaque, Humans, Records, Child, Tooth
Abstract: The aim of this study was to establish the association between features regarding brushing procedure performed by schoolchildren without previous formal training and the effectiveness of biofilm removal. Out of a population of 8900 6- and 7-year-old schoolchildren in Buenos Aires City, 600 children were selected from schools located in homogeneous risk areas. Informed consent was requested from parents or guardians and formal assent was obtained from children themselves. The final sample consisted of 316 subjects. The following tooth brushing variables were analyzed: toothbrush-gripping, orientation of active part of bristles with respect to the tooth, type of movement applied, brushing both jaws together or separately, including all 6 sextants and duration of brushing. The level of dental biofilm after brushing was determined by O'Leary's index, acceptable cut-off point = 20%. Four calibrated dentists performed observations and clinical examinations. Frequency distribution, central tendency and dispersion measures were calculated. Cluster analyses were performed; proportions of variables for each cluster were compared with Bonferroni's correction and OR was obtained. The most frequent categories were: palm gripping (71.51%); perpendicular orientation (85.8%); horizontal movement (95.6%); separate addressing of jaws (68%) and inclusion of all 6 sextants (50.6%). Mean duration of brushing was 48.78 ± 27.36 seconds. 42.7% of the children achieved an acceptable biofilm level. The cluster with the highest proportion of subjects with acceptable post-brushing biofilm levels (p0.05) differed significantly from the rest for the variable "inclusion of all 6 sextants in brushing procedure". OR was 2.538 (CI 95% 1.603 - 4.017). Inclusion of all six sextants could be a determinant variable for the removal of biofilm by brushing in schoolchildren, and should be systematized as a component in oral hygiene education.El objetivo del trabajo fue establecer la asociación entre las características del procedimiento de cepillado en escolares sin previo entrenamiento formal con la efectividad para el barrido del biofilm dental. Sobre una población de 8900 escolares de Ciudad Autónoma de Buenos Aires de 6 y 7 años de edad, se seleccionaron 600 niños concurrentes a escuelas situadas en áreas de riesgo homogéneo. Sobre esta muestra se solicito consentimiento informado a los responsables legales y el asentimiento formal, conformando una muestra final de 316 individuos. Se analizaron las siguientes variables del procedimiento de cepillado: tipo de toma del cepillo dental, orientación de la parte activa respecto del diente, tipo de movimiento aplicado, abordaje simultaneo o no de ambos maxilares, inclusión de los 6 sextantes y duración de cepillado. El nivel de biofilm dental posterior al cepillado se determinó con el índice de O’Leary-punto de corte aceptable=20%. Cuatro odontólogos calibrados realizaron las observaciones y exámenes clínicos. Se calculó: distribución de frecuencias, medidas de tendencia central y su dispersión. Se realizó un análisis de clúster y comparación de proporciones de las variables de cada conglomerado con corrección de Bonferroni y OR. Las categorías más frecuentes fueron: toma palmar (71,51%); orientación perpendicular (85,8%); movimiento horizontal (95,6%); cepillado de ambos maxilares por separado (68%) e inclusión de los 6 sextantes (50,6%).La media de duración del cepillado fue de 48.78 ± 27.36 segundos. El42,7 % de los escolares alcanzaron un nivel de biofilm aceptable. El clúster que mostró la mayor proporción de individuos con niveles de biofilm postcepillado aceptables (p0,05) mostró diferencias estadísticamente significativas con los demás respecto de la variable “inclusión de 6 sextantes en el cepillado”. El OR fue igual a 2,538 (IC 95% 1,603 – 4,017). La inclusión de los seis sextantes podría ser una variable determinante de la efectividad del barrido de biofilm mediante el cepillado en escolares debiendo enfatizarse la sistematización del mismo como componente de la enseñanza de higiene bucal.

155. Interaction Effect between Herbivory and Plant Fertilization on Extrafloral Nectar Production and on Seed Traits: An Experimental Study with Ricinus communis (Euphorbiaceae)

Abstract: Made available in DSpace on 2018-12-11T16:43:39Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-08-01 It is known that the release of volatile chemicals by many plants can attract the natural enemies of herbivorous insects. Such indirect interactions are likely when plants produce nectar from their extrafloral nectaries, and particularly when the production of extrafloral nectar (EFN) is induced by herbivory. In the present study, we conducted experiments to test whether foliar herbivory inflicted by Spodoptera frugiperda Smith (Noctuidae) increases nectar production by extrafloral nectaries on one of its host plants, Ricinus communis L. (Euphorbiaceae). Due to the current economic importance of R. communis, we also investigated whether the following seed traits - water content, dry mass, and essential oil production - are negatively affected by herbivory. Finally, we tested whether or not nectar production and seed traits are influenced by plant fertilization (plant quality). We found that nectar production was increased after herbivory, but it was not affected by the type of fertilization. Seed dry mass was higher in plants that were subjected to full fertilization, without herbivory; plants maintained in low fertilization conditions, however, had higher seed mass when subjected to herbivory. The same inverted pattern was observed for oil production. Therefore, our results suggest that EFN production in R. communis may act as an indirect defense strategy against herbivores, and that there is a trade-off between reproduction and plant growth when low-fertilized plants are subjected to herbivory.

Abstract: International audience; The large size and the very low radioactive background of solar neutrino detectors such as Borexino at the Gran Sasso Laboratory in Italy offer a unique opportunity to probe the existence of neutrino oscillations into new sterile components by means of carefully designed and well calibrated anti-neutrino and neutrino artificial sources. In this paper we briefly summarise the key elements of the SOX experiment, a program for the search of sterile neutrinos (and other short distance effects) by means of a (144)Ce-(144)Pr anti-neutrino source and, possibly in the medium term future, with a (51)Cr neutrino source.

Abstract: The existence of dark matter is inferred from gravitational effects, but its nature remains a deep mystery. One possibility, motivated by considerations in elementary particle physics, is that dark matter consists of elementary particles, such as the hypothesized Weakly Interacting Massive Particles (WIMPs), with mass ~ 100 GeV and cross-section ~ 10−47 cm2, that can be gravitationally trapped inside our galaxy and revealed by their scattering on nuclei. It should be possible to detect WIMPs directly, as the orbital motion of the WIMPs composing the dark matter halo pervading the galaxy should result in WIMP-nucleus collisions of sufficient energy to be observable in the laboratory. The DarkSide-50 experiment is a direct WIMP search using a Liquid Argon Time Projection Chamber (LAr-TPC) with an active mass of 50 kg with a high sensitivity and an ultra-low background detector.

Abstract: We report the first results of DarkSide-50, a direct search for dark matter operating in the un- derground Laboratori Nazionali del Gran Sasso (LNGS) and searching for the rare nuclear recoils possibly induced by weakly interacting massive particles (WIMPs). The dark matter detector is a Liquid Argon Time Projection Chamber with a ( 46.4 0.7 ) kg active mass, operated inside a 30 t or- ganic liquid scintillator neutron veto, which is in turn installed at the center of a 1 kt water Cherenkov veto for the residual flux of cosmic rays. We report here the null results of a dark matter search for a ( 1422 67 ) kg d exposure with an atmospheric argon fill. This is the most sensitive dark matter search performed with an argon target, corresponding to a 90% CL upper limit on the WIMP-nucleon spin-independent cross section of 6.1 10

Abstract: It is generally inferred from astronomical measurements th at Dark Matter (DM) comprises approximately 27% of the energy-dens ity of the universe. If DM is a subatomic particle, a possible candidate is a Weakl y Interacting Mas- sive Particle (WIMP), and the DarkSide-50 (DS) experiment i s a direct search for evidence of WIMP-nuclear collisions. DS is located undergr ound at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy, and consists of thr ee active, embedded components; an outer water veto (CTF), a liquid scintillato r veto (LSV), and a liquid argon (LAr) time projection chamber (TPC).

Abstract: Introduction: Familial hypercholesterolaemia (FH) is a common genetic cause of premature coronary heart disease (CHD) due to lifelong elevated plasma low-density lipoprotein (LDL) levels. Worldwide only 40 % of patients (FH+) with a clinical diagnosis of FH carry a mutation in any of the three genes (namely: LDLR, APOB, PCSK 9) that are currently known to be associated to the disease. We guess that the remaining 60 % of the patients (FH-) probably includes a high percentage of individuals with a polygenic form of dyslipidemia or an environmental form of hypercholesterolemia and a small percentage of individuals with mutations in some novel genes, never associated before with dyslipidemias. Here we present the preliminary results of an integrative approach intended to identify new candidate genes and to dissect pathways that can be dysregulated in the disease. N.

161. The effect of seed traits on geographic variation in body size and sexual size dimorphism of the seed-feeding beetle

Subjects: intraspecific variation, evolutionary ecology, Ecological variables, seed quality, latitudinal and altitudinal clines, Original Research
Abstract: Explaining large‐scale patterns of variation in body size has been considered a central question in ecology and evolutionary biology because several life‐history traits are directly linked to body size. For ectothermic organisms, little is known about what processes influence geographic variation in body size. Changes in body size and sexual size dimorphism (SSD) have been associated with environmental variables, particularly for Bruchinae insects, which feed exclusively on seeds during the larval stage. However, the effect of important seed traits on body size variation has rarely been investigated, and whether SSD varies substantially among populations within bruchine species is poorly known. Using the seed‐feeding beetle Acanthoscelides macrophthalmus infesting its host plant Leucaena leucocephala, we investigated whether specific seed traits (hardness, size, water content, carbon/nitrogen ratio, and phenolic content) were determinant in generating geographic variation in body size and SSD of A. macrophthalmus. We also examined the relationships between body size and SSD with latitude and altitude. The body size of both sexes combined was not related to latitude, altitude, and any of the physical and chemical seed traits. However, the female body size tended to vary more in size than the males, generating significant variation in SSD in relation to latitude and altitude. The females were the larger sex at higher latitudes and at lower altitudes, precisely where seed water content was greater. Therefore, our results suggest that water content was the most important seed trait, most severely affecting the females, promoting geographic variation in SSD of A. macrophthalmus.

Such indicators are particularly needed in the present context of European legislation (Marine Strategy Framework Directive). However, zooplankton have not been given the interest they should have in regards to these issues. The aim of the present study is to provide an attempt of proposition of indicators of good environmental status and associated thresholds based on zooplankton data. Zooplankton time-series (2002–2013) from the Toulon Bay in the Mediterranean was used. This time-series presents the great characteristics that the sampling has be done jointly in two areas of the Bay of Toulon known to differ in term of anthropogenic pressures. The study focus on the copepod assemblage and different potential indicators are tested: ratio of copepod families on total copepod and diversity index (Piélou's evenness). The indicators relevance was evaluated per season by looking at the importance of the overlapping region between density's distributions for each indicator in both bays. This methodology well-recognized is commonly used, particularly in the medical sector, for a long time. The results show that the Oithonidae relative abundance and the Piélou's evenness index are the best indicators of anthropogenic pollution for this case study. Thresholds related to the selected indicators are also proposed in order to characterize the degree of anthropogenic pressure for the Toulon Bay and to provide a first evaluation for potential environmental management. Applicability of the selected indicators and future development needed are also discussed. This study is a first step in the investigation for operational zooplankton indicators and should open the way for additional studies in coastal anthropized area such as the Mediterranean coast where it is more urgently needed. &

Abstract: International audience; In order to perform a resolutive measurement to clarify the neutrino anomalies and to observe possible short distance neutrino oscillations, the SOX (Short distance neutrino Oscillations with BoreXino) experiment is under construction. In the first phase, a 100 kCi (144)Ce-(144)Pr antineutrino source will be placed under the Borexino detector at the Laboratori Nazionali del Gran Sasso (LNGS), in center of Italy, and the rate measurement of the antineutrino events, observed by the very low radioactive background Borexino detector, will be compared with the high precision (< 1%) activity measurement performed by two calorimeters. The source will be embedded in a 19 mm thick tungsten alloy shield and both the calorimeters have been conceived for measuring the thermal heat absorbed by a water flow. In this report the design of the calorimeters will be described in detail and very preliminary results will be also shown.

Abstract: International audience; The DarkSide program at LNGS aims to perform background-free WIMP searches using two phase liquid argon time projection chambers, with the ultimate goal of covering all parameters down to the so-called neutrino floor. One of the distinct features of the program is the use of underground argon with has a reduced content of the radioactive $^{39}$Ar compared to atmospheric argon. The DarkSide Collaboration is currently operating the DarkSide-50 experiment, the first such WIMP detector using underground argon. Operations with underground argon indicate a suppression of $^{39}$Ar by a factor (1.4 ± 0.2) × 10$^3$ relative to atmospheric argon. The new results obtained with DarkSide-50 and the plans for the next steps of the DarkSide program, the 20t fiducial mass DarkSide-20k detector and the 200 t fiducial Argo, are reviewed in this proceedings.

Abstract: International audience; Borexino is an unsegmented neutrino detector operating at LNGS in central Italy. The experiment has shown its performances through its unprecedented accomplishments in the solar and geoneutrino detection. These performances make it an ideal tool to accomplish a state- of-the-art experiment able to test the existence of sterile neutrinos (SOX experiment). For both the solar and the SOX analysis, a good understanding of the detector response is fundamental. Consequently, calibration campaigns with radioactive sources have been performed over the years. The calibration data are of extreme importance to develop an accurate Monte Carlo code. This code is used in all the neutrino analyses. The Borexino-SOX calibration techniques and program and the advances on the detector simulation code in view of the start of the SOX data taking are presented. (1)

Abstract: Measurements were made of scintillation light yield of alpha particles from the $^{222}$Rn decay chain within the DarkSide-50 liquid argon time projection chamber. The light yield was found to increase as the applied electric field increased, with alphas in a 200 V/cm electric field exhibiting a 2% increase in light yield compared to alphas in no field., Comment: 5 pages, 5 figures

Abstract: International audience; Nuclear recoil events produced by neutron scatters form one of the most important classes of background in WIMP direct detection experiments, as they may produce nuclear recoils that look exactly like WIMP interactions. In DarkSide-50, we both actively suppress and measure the rate of neutron-induced background events using our neutron veto, composed of a boron-loaded liquid scintillator detector within a water Cherenkov detector. This paper is devoted to the description of the neutron veto system of DarkSide-50, including the detector structure, the fundamentals of event reconstruction and data analysis, and basic performance parameters.

Abstract: International audience; DarkSide-50 is a direct dark matter search experiment operating underground at Laboratori Nazionali del Gran Sasso. It is based on a Time Projection Chamber (TPC) that contains 50 kg of liquid argon; the TPC cryostat sits inside an active neutron veto based on a boron-loaded organic scintillator, which is in turn installed inside a water Cherenkov muon veto. The experiment started acquiring data in Nov 2013 filled with atmospheric argon. In April 2015 it commissioned the low-radioactivity argon from underground sources and has been running in a stable manner since then. We report the current status of the detector and the latest results, including the measurement of the radioactivity of the underground argon and the most sensitive dark matter search performed with an argon target.

Abstract: In this report we describe the unique capabilities of the $ \alpha / \beta$ discrimination of the Borexino experiment. This capability is the direct result of years of development aimed at the design of an experiment that could withstand contamination from $ \alpha$-emitting nuclides. The combination of the excellent $ \alpha/\beta$ discrimination and of the excellent radiopurity of the detector permitted to extract information on the solar neutrino interactions in Borexino without interference from $ \alpha$ particles.

Abstract: International audience; The Borexino experiment is running at the Laboratori del Gran Sasso in Italy since 2007. Its technical distinctive feature is the unprecedented ultralow background of the inner scintillating core, which is the basis of the outstanding achievements accumulated by the experiment. In this talk, after recalling the main features of the detector, the impressive solar data gathered so far by the experiment will be summarized, with special emphasis to the most recent and prominent result concerning the detection of the fundamental pp solar neutrino flux, which is the direct probe of the engine mechanism powering our star. Such a milestone measurement puts Borexino in the unique situation of being the only experiment able to do solar neutrino spectroscopy over the entire solar spectrum, the counterpart of this peculiar status in the oscillation interpretation of the data is the capability of Borexino alone to perform the full validation across the solar energy range of the MSW-LMA paradigm. The talk will be concluded highlighting the perspectives for the final stage of the solar program of the experiment, centered on the goal to fully complete the solar spectroscopy with the missing piece of the CNO neutrinos. If successful, such a measurement would represent the final crowning of the long quest of Borexino to unravel all the properties of the neutrinos from the Sun.

Abstract: Precision measurements of solar neutrinos emitted by specific nuclear reaction chains in the Sun are of great interest for developing an improved understanding of star formation and evolution. Given the expected neutrino fluxes and known detection reactions, such measurements require detectors capable of collecting neutrino-electron scattering data in exposures on the order of 1 ktonne yr, with good energy resolution and extremely low background. Two-phase liquid argon time projection chambers (LAr TPCs) are under development for direct Dark Matter WIMP searches, which possess very large sensitive mass, high scintillation light yield, good energy resolution, and good spatial resolution in all three cartesian directions. While enabling Dark Matter searches with sensitivity extending to the "neutrino floor" (given by the rate of nuclear recoil events from solar neutrino coherent scattering), such detectors could also enable precision measurements of solar neutrino fluxes using the neutrino-electron elastic scattering events. Modeling results are presented for the cosmogenic and radiogenic backgrounds affecting solar neutrino detection in a 300 tonne (100 tonne fiducial) LAr TPC operating at LNGS depth (3,800 meters of water equivalent). The results show that such a detector could measure the CNO neutrino rate with ~15% precision, and significantly improve the precision of the 7Be and pep neutrino rates compared to the currently available results from the Borexino organic liquid scintillator detector., Comment: 21 pages, 7 figures, 6 tables

Abstract: The Borexino detector has convincingly shown its outstanding performance in the in the sub-MeV regime through its unprecedented accomplishments in the solar and geo-neutrinos detection, which make it the ideal tool to unambiguously test the long-standing issue of the existence of a sterile neutrino, as suggested by several anomalies: the outputs of the LSND and Miniboone experiments, the results of the source calibration of the two Gallium solar ν experiments, and the recently hinted reactor anomaly. The SOX project will exploit two sources, based on chromium and cerium, which deployed under the experiment will emit two intense beams of ν e (Cr) and ν e ‾ (Ce). Interacting in the active volume of the liquid scintillator, each beam would create a spatial wave pattern in case of oscillation of the ν e (or ν e ‾ ) into the sterile state, which would be the smoking gun proving the existence of the new sterile member of the neutrino family. Otherwise, its absence will allow setting very stringent limit on its existence.

Abstract: International audience; The aim of the SOX-Borexino project is to verify or falsify the existence of eV-scale sterile neutrinos. The existence of sterile neutrinos is suspected because of several anomalies, which were observed in previous experiments. A ~3.7 PBq electron antineutrino source made of$^{144}$Ce will be installed below the Borexino detector at LNGS, Italy, to search for short-baseline oscillations of active-to-sterile neutrinos within the detector volume. Source delivery and beginning of data acquisition is planned for end of 2016, preliminary results are expected already in 2017.

Abstract: In this study, seed predation rates imposed by bruchines and the composition of bruchine species and their host plants were assessed in a heterogeneous landscape in southeastern Brazil. Fruits were collected from 49 plants from 16 species belonging to four families, primarily Fabaceae. The five bruchine species collected emerged from four plant species as follows: Acanthoscelides macrophthalmus (Schaeffer) from Leucaena leucocephala (Lamarck) de Wit, Acanthoscelides sp. from Senna hirsuta (L.) Irwin and Barneby, Ctenocolum podagricus (F.) from Lonchocarpus muehlbergianus Hassler, and Gibbobruchus polycoccus (Fahraeus) and Gibbobruchus speculifer (Gyllenhal) from Bauhinia forficata Link. Bauhinia forficata is here recorded for the first time as a host for G. polycoccus. Only 1/4 of the local flora that was surveyed hosted bruchines. Bruchine and plant species composition varied among habitats, with most beetles found in plants located in the most disturbed habitat. Because of the economic importance of L. leucocephala in the tropics, we compared germination percentages between attacked and unattacked seeds of this species. The unattacked seeds had an average germination rate of 59%, and none of the attacked seeds germinated, showing that the germination of L. leucocephala seeds was drastically affected by predation.

As plantas localizadas na borda estão mais expostas a distúrbios e variações microclimáticas do que as plantas do interior, resultando no chamado efeito de borda. Neste estudo, a área foliar, a assimetria flutuante e os caracteres químicos das folhas (água, nitrogênio e taninos) foram comparados entre plantas de Erythroxylum tortuosum situadas na borda e no interior de um fragmento de cerrado brasileiro. A variação temporal de eventos fenológicos vegetativos e reprodutivos de E. tortuosum também foi investigada durante o período de estudo. Nitrogênio, área foliar e assimetria flutuante não diferiram entre os dois grupos de plantas. As folhas jovens das plantas localizadas na borda apresentaram, significativamente, níveis mais altos de taninos e menores níveis de água do que as plantas do interior. Sugere-se que as diferenças nos conteúdos químicos foliares entre as plantas da borda e do interior devem ter ocorrido em razão de fatores como intensidade luminosa, vento, temperatura e idade foliar e não por causa do nível de estresse da planta. Com relação à fenologia, a maioria dos eventos reprodutivos ocorreu durante a primavera. Os botões foliares e as folhas novas prevaleceram durante a estação chuvosa. No entanto, na estação seca, os eventos vegetativos decresceram por causa da senescência das folhas, seguida pela abscisão foliar. The edge of a forest fragment can be considered a zone of transition between the interior of the fragment and the surrounding habitat matrix. Plants along the edge are more exposed to disturbance and microclimate variation than interior plants, resulting in the so-called edge effect. In this study, we compared leaf area, fluctuating asymmetry and chemical (water, nitrogen and tannins) leaf traits between Erythroxylum tortuosum plants inhabiting the edge with those growing in the interior of a cerrado fragment in Brazil. We also describe the temporal variation in the vegetative and reproductive phenological events of E. tortuosum plants throughout the season. Nitrogen, leaf area and fluctuating asymmetry did not differ between the two plant groups. Young leaves of the edge plants had significantly higher levels of tannins and lower levels of water than those of interior plants. We suggest that differences in leaf chemical concentrations between edge and interior plants may occur due to factors such as light intensity, wind, temperature and leaf age rather than plant stress. With respect to plant phenology, most reproductive events occurred during the spring. Leaf buds and young leaves prevailed during the rainy season. In the dry season, however, the vegetative events decreased due to leaf senescence followed by leaf abscission.

180. Basin evolution of the margin of Gondwana at the Neoproterozoic/Cambrian transition: the Puncoviscana Formation of Northwest Argentina

Abstract: The Puncoviscana Formation is an important stratigraphic sequence of sandstones and shales, with intercalated conglomerates, limestones and volcanic rocks. It was deposited at the Neo- proterozoic-Cambrian boundary in a shallow basin on the western margin of Gondwana. Trace fos- sils of the Puncoviscana Formation s.l. are represented by the Oldhamia and Nereites ichnoassocia- tions and the geographical distribution of assemblages are aligned as parallel belts, with a shallower eastern Nereites association and a deeper western Oldhamia association. They represent different temporal levels on the evolution of the basin. Detrital zircon spectra display a wide range of ages, which indicate their provenance from Neoproterozoic to Cambrian source areas as well as Meso- to Paleoproterozoic basement units, exhibiting typical Gondwanan ages. Thick limestone banks are interbedded in the Puncoviscana Formation s.l. that included the siliciclastic sequences, with very low- to medium-metamorphic grade. δ13C values for the limestones vary from -1.57 to +3.40/00 VPDB, while in the Sierras Pampeanas, δ13C values vary from +2.6 to +80/00 VPDB. Also, reported 87Sr/86Sr values allow a clear differentiation of two rock sets. The limestones interbedded with the Puncoviscana Formation yielded values typical for the Neoproterozoic-Cambrian transition, between 0.70868 and 0.70896; while the limestones of the Sierras Pampeanas display values between 0.70748 and 0.70756, common in the middle to late Ediacaran. Deformation and uplift of the Puncoviscana Formation is clearly represented in northern Argentina by the Tilcarian unconformity, which is over- lain by the Meson Group.

Abstract: The Early Ordovician granitoids of the Sierra de Velasco reflect the across-arc compositional variation of the Famatinian magmatic arc (NW Argentina) developed along the proto-Andean margin of western Gondwana. This variation is characterized by means of field, petrographical, geochemical and isotopic studies. The Sierra de Velasco contains three main types of Early Ordovician granitoids that are mineralogically and geochemically distinct, but generally conform a continuous high-K, magnesian and calcalkalic magmatic series. I-type granitoids (IG) make up the southern part of the range. They are biotite-hornblende-titanite metaluminous to weakly peraluminous granodiorites and tonalites typical of a coastal I-type belt and were possibly formed by melting of mafic lower crust/lithospheric mantle, with minor assimilation of crustal metasediments. S-type granitoids (SG) crop out in the central and northern portions of the range. They are biotite-muscovite and biotite-cordierite strongly peraluminous syeno- andmonzogranites representative of an inland S-type belt and were possibly formed by large-scaleanatexis of metasedimentary crust and hybridization with more mafic lower crustal melts. Between the IG and SG, in the central parts of the range, transitional I/S-type granitoids (TG) are recognized that consist of biotite, biotite-muscovite and subordinate biotite-titanite-allanite-epidote moderately peraluminous monzogranites, granodiorites and tonalites. The TG show intermediate characteristics and were possibly generated by less common mechanisms of mixing between I-type and S-type magmas and/or their parent mafic lower crustal and metasedimentary melts. The transition from IG to TG to SG towards the continental interior reflects a compositional continuum related to a progressive variation in the degrees of mixing between mafic and metasedimentary end-members.

Abstract: Spatial and temporal variation of pre-dispersal seed predation was investigated in a population of Mimosa bimucronata trees located in the south-east region of Brazil. Three main hypotheses were addressed: (1) that the life stages of the seed predator Acanthoscelides schrankiae are synchronised with the reproductive stages of its host plant; (2) that seed predation levels vary spatially as a result of differences in fruiting phenology synchrony and fruit production among trees; and (3) that predation levels should be affected by the proximity of trees, showing a spatial structure. Also investigated was the oviposition pattern of A. schrankiae among seeds and fruits. Twenty spatially referenced trees were monitored throughout a year to examine tree phenology and egg laying and adult emergence. The bruchine’s life stages were synchronised with the reproductive stages of M. bimucronata trees. Egg distribution among seeds and fruits was aggregated. Infestation rates of adult bruchines were not spatially related to fruiting phenology and there is evidence that seed predation is a spatially density-independent process, because the relationship between infestation rates and fruit production was not significant. Finally, it was observed that the distribution of adult bruchines was spatially structured, because similar levels of infestation were found among nearby trees.

184. Leaf trait variation on Erythroxylum tortuosum (Erythroxylaceae) and its relationship with oviposition preference and stress by a host-specific leaf miner

Abstract: It has been suggested that plant physical and chemical traits vary considerably in space and time. Hence, leaf-mining insects may adjust their oviposition in response to leaf attributes representing high quality. Moreover, herbivorous insects can modify leaf morphology by acting as stressors, increasing, for example, fluctuating asymmetry (FA) levels. Here, we investigate oviposition preference in Agnippe sp.2, a leaf-mining moth of Erythroxylum tortuosum, in relation to differences in leaf nutritional quality (i.e. levels of water, nitrogen and tannin content), leaf area (i.e. quantity of resource hypothesis) and FA. We also verify whether temporal variation in plant nutritional quality emerges as an alternative hypothesis to explain oviposition distribution in time, and whether this leaf miner is a stress-causing agent, increasing FA during larval development. Mined leaves and leaves with and without eggs were periodically collected from plants located in a Cerrado fragment in Brazil. In the laboratory, leaf traits were assessed (using image analysis software) and quantified (biochemical analysis) according to the aims previously determined. Oviposition probability did not change in relation to variations in nitrogen, tannins and FA of leaves. However, leaf-miner females preferred to oviposit on leaves having large areas and low water contents. It was also verified that new leaves of E. tortuosum, which carried most leaf-miner eggs, presented significantly lower tannins and greater levels of nitrogen and water than old leaves. The oviposition choice exhibited by leaf miners was found to be non-random because they appear to use resource quantity and water content as cues as where to lay their eggs. The temporal variation of plant nutritional quality is likely to influence the time of leaf-miner oviposition; and leaf FA was not increased during larval feeding, suggesting that these herbivores do not cause variations in FA levels.

185. High T/P evolution and metamorphic ages of the migmatitic basement of northern Sierras Pampeanas, Argentina: Characterization of a mid-crustal segment of the Famatinian belt

Abstract: New petrologic, thermobarometric and U-Pb monazite geochronologic information allowed to resolve the metamorphic evolution of a high temperature mid-crustal segment of an ancient subduction-related orogen. The El Portezuelo Metamorphic-Igneous Complex, in the northern Sierras Pampeanas, is mainly composed of migmatites that evolved from amphibolite to granulite metamorphic facies, reaching thermal peak conditions of 670–820 °C and 4.5–5.3 kbar. The petrographic study combined with conventional and pseudosection thermobarometry led to deducing a short prograde metamorphic evolution within migmatite blocks. The garnet-absent migmatites represent amphibolite-facies rocks, whereas the cordierite-garnet-K-feldspar-sillimanite migmatites represent higher metamorphic grade rocks. U-Pb geochronology on monazite grains within leucosome record the time of migmatization between ≈477 and 470 Ma. Thus, the El Portezuelo Metamorphic-Igneous Complex is an example of exhumed Early Ordovician anatectic middle crust of the Famatinian mobile belt. Homogeneous exposure of similar paleo-depths throughout the Famatinian back-arc and isobaric cooling paths suggest slow exhumation and consequent longstanding crustal residence at high temperatures. High thermal gradients uniformly distributed in the Famatinian back-arc can be explained by shallow convection of a low-viscosity asthenosphere promoted by subducting-slab dehydration.

Abstract: The effects of nanogel encapsulation of recombinant NcPDI (recNcPDI) following vaccination of mice by intranasal or intraperitoneal routes and challenge infection with Neospora caninum tachyzoites were investigated. Nanogels were chitosan based, with an alginate or alginate-mannose surface. None of the mice receiving recNcPDI intraperitoneal (i.p.) (without nanogels) survived, whereas intranasal (i.n.) application protected 9 of 10 mice from disease. Association of recNcPDI with nanogels improved survival of i.p. vaccinated mice, but nanogels without recNcPDI gave similar protection levels. When nanogels were inoculated via the i.n. route, 80% of the mice were protected. Association of recNcPDI with the alginate-coated nanogels protected all mice against disease. Quantification of the cerebral parasite burden showed a significant reduction of parasite numbers in most experimental groups vaccinated i.n., except those vaccinated with alginate-mannose nanogels with or without recNcPDI. For i.p. vaccinated groups, no significant differences in cerebral infection densities were measured, but there was a reduction in the groups vaccinated with recNcPDI associated with both types of nanogels. Analysis of the immune responses of infected mice indicated that association of recNcPDI with nanogels altered the patterns of cytokine mRNA expression profiles, but had no major impact on the antibody subtype responses. Nevertheless, this did not necessarily relate to the protection.

Abstract: In the Sierra de Velasco, northwestern Argentina, undeformed Lower Carboniferous granitoids (350–334 Ma) intrude deformed Lower Ordovician granites and have been emplaced by passive mechanisms, typical of tensional environments. The semi-elliptic, about 300 km shallow-emplaced San Blas pluton is 340–330 Ma old, with 1Ndt between 21.3 and 21.8 which indicates that, different from the nearby Famatinian–Ordovician granitoids, the San Blas pluton had a relatively brief crustal residence, with an interaction between asthenospheric material and greywackes. The cupola of the pluton was almost totally eroded down during the Upper

Abstract: This paper reports part of the results of the campaigns performed on a low NO x burner, firing natural gas in oxy-fuel conditions. The results of combustion tests on burning natural gas with different flue gas recycle rates are presented, with a particular emphasis on NO x production that might affect retrofitting of oxy-fuel technology in conventional boilers. The process and flame characterisation performed on natural gas provides a valuable set of experimental data for the technological development of oxy-combustion burner technology with recycled flue gas, especially in retrofitting scenarios. The data can be used to develop a better understanding of the chemical and physical phenomena involved in oxy-fuel combustion and can provide modellers with a valuable hint for the development of specific sub-models for oxy-combustion simulation. Since is seems technologically unfeasible to reduce down to zero the presence of nitrogen in recycled flue gases, due to air in-leakages, the presence of relatively small amounts of nitrogen in crucial location in the burner provides a thermal NO x source, depending on local levels of temperature and oxygen concentration.

Abstract: Resumen. Despues del fuego, la germinacion de semillas que poseen tegumento duro puede aumentar. En el presente estudio investigamos si la germinacion de semillas de Mimosa bimucronata (DC.) Kuntze (Fabaceae), cuyos tegumentos son duros, aumenta despues del fuego, a pesar de que estos arboles por lo general son de areas humedas, donde el fuego es un evento raro. Los incendios fueron provocados en bandejas llenas de tierra cubierta con cantidades diferentes de pasto seco, caracterizando tres tratamientos: a) 0g (grupo control); b) 300g, y c) 450g de pasto seco. Las semillas fueron localizadas en la superficie o enterradas en el suelo que iba a ser quemado. Los experimentos de germinacion fueron realizados en los tiempos 0-h y 24-h despues del fuego para obtener los porcentajes y el Indice de Velocidad de Germinacion (IVG). Los resultados mostraron que para el grupo control y para el grupo con 300g de pasto seco la germinacion de las semillas enterradas fue significativamente mayor que en el grupo con 450g de pasto. Por otra parte, el IVG fue significativamente mas alto con el tratamiento de 300g. No se observaron diferencias significativas entre los tiempos 0-h y 24-h. Las semillas colocadas en la superficie del suelo no sobrevivieron a la quema. Nuestro estudio mostro que aunque las temperaturas alrededor de 100 °C disminuyen significativamente la capacidad germinativa de las semillas de M. bimucronata, cuando fueron enterradas el porcentaje de germinacion no fue diferente entre el grupo control y el tratamiento con 300g. Los resultados tambien sugieren que temperaturas alrededor de 60 °C pueden aumentar la velocidad de germinacion de las semillas de M. bimucronata.

Abstract: The Velasco orbicular granitoid is a small (65 × 15 m), irregularly-shaped body that cropsout within the Huaco granite, central Sierra de Velasco, NW Argentina. It consists of ellipsoid-shapedorbicules of 3 to 15 cm length immersed in an aplitic to pegmatitic matrix. The orbicules are formedby a core made up of a K-feldspar megacryst, partially to totally replaced by plagioclase, an inner shellof radial and equant plagioclase crystals, a layer of tangentially oriented biotite laths, and an outer shellof plumose plagioclase crystals, containing diffuse rings of tangentially oriented biotite. The orbiculargranitoid formed in situ in a pocket of evolved and volatile-rich melt segregated from the surroundingpartially crystallized Huaco granite, possibly via a filter pressing mechanism. The segregated meltentrained relatively few K-feldspar megacrysts into the pocket, leaving behind a concentration ofmegacrysts around the pocket. High water concentration caused effective superheating of the meltand destruction of nuclei, with only the large megacrysts surviving as solids. Sudden water-pressureloss and exsolution of the volatile phase, perhaps related to a volcanic eruption or fracturing of thesurrounding granite, caused rapid undercooling of the melt. The orbicules grewin the undercooled meltby heterogeneous nucleation on the megacrysts, which acted as nucleation seeds, and crystallizationof reversely zoned radial plagioclase and sporadic crystallization of tangential biotite rings accordingto fluctuations in its saturation. Orbicular growth gave way to crystallization of the equiaxial interorbicularmatrix in two stages, when sufficient polymerization of the melt was attained. The time scaleof formation of the orbicular granitoid was fast, possibly a matter of a few weeks or months. Fil: Grosse, Pablo. Consejo Nacional de Investigaciones Científicas y Técnicas.

Abstract: Phenolic contents were compared between Mimosa bimucronata seeds from infested and non-infested fruits to assess induced defense response. By measuring leg length of the bruchid beetle Acanthoscelides schrankiae, we verified whether phenolic contents affected bruchid body size. In addition, the relationship between physical seed traits and phenolic contents was examined. Results showed that seeds from infested fruits had significantly greater phenolic contents than seeds from non-infested fruits, which suggested induced defense. Body size variation in A. schrankiae was marginally nonsignificant according to phenolic contents among plants (negative trend), indicating that phenols may interfere directly with bruchid performance. Seeds that were more irregularly shaped had significantly greater phenolic contents than those that were more uniform. Therefore, the most perfectly spherical seeds may be more vulnerable to seed predation, and our results suggest that the production of phenolic compounds was increased in infested fruits, which in turn may affect A. schrankiae development.

Abstract: Mimosa bimucronata is a pioneering tree that occurs predominantly in moist lowlands, floodplains and on margins of rivers and lakes in Latin America. The effect of submergence on seed germination in M. bimucronata was firstly studied. Patterns of water absorption by M. bimucronata seeds were investigated thereafter to assess the imbibition phases of scarified and unscarified seeds. The germination percentage was significantly higher in scarified than in unscarified seeds, and the velocity of seed germination also increased considerably in scarified seeds. Submergence duration did not significantly affect germination percentages of scarified and unscarified seeds. Therefore, seed viability after submersion suggests that M. bimucronata may display hydrochorous dispersal and also that seeds are able to germinate successfully in areas with frequent seasonal flooding. With respect to imbibition phases, phase II was very short or even absent for scarified and unscarified seeds; therefore, a plateau, where water absorption by seeds is established, was not observed. Finally, we verified that the passage from phase I to III was very tenuous and took a long time in seeds without scarification.

Abstract: Four children with symptoms consistent with complicated migraine had CSF pleocytosis, in three cases lymphocytic and in the fourth polymorphonuclear. In one case the CSF abnormality was found during two separate attacks of complicated migraine. On the basis of the 23 cases reported in the literature and these four personal cases, the authors conclude that, as a rule, pleocytosis is a secondary phenomenon of an attack of complicated migraine. However, in exceptional cases an infectious disease might produce both a migraine attack and CSF pleocytosis.

Abstract: SUMMARY 64 full-term and three preterm, normal infants, appropriate for gestational age (AGA), were tested for the appearance of vestibular response to rotatory stimulation at a minimal postconceptional age of 44 weeks. A total of 56 positive responses was obtained. The majority of the full-term AGA infants responded by the 45th postconceptional week (60 per cent of the 50 infants tested at that age). Greater duration of extra-uteri ne life significantly accelerated the appearance of the response. The influence of intra-uterine growth retardation on the appearance of vestibular responses was also invested in 27 full-term and seven pre-term infants who were small for gestational age (SGA). 30 positive responses were obtained, but a significantly lower percentage of the full-term SGA infants showed a positive response by the 45 th postconceptional week compared with the full-term AGA infants. This suggests that abnormal intra-uterine conditions have an effect on maturation of vestibular responses. RESUME La maturation des reponses vestibulaires chez le nourrisson.

La majorite des nourrissons nes a terme AGA ont repondu durant la 45eme semaine post-conceptionnelle (60 pour cent des 50 nourrissons observes a cet age).

Les nourrissons SGA nes a terme ont monte un pourcentage significativement plus bas de reponses positives a la 45eme semaine post-conceptionnelle par comparaison avec les nourrissons AGA nes a terme. Chez les nourrissons SGA la reponse apparut plus tard. Il semble done que des conditions intra-uterines anormals affectent la maturation des reponses vestibulaires.

Die Mehrzahl der reifen Neugeborenen zeigte eine positive Vestibularisreaktion im Konzeptionsalter von 45 Wochen (60 Prozent der 50 untersuch-ten Kinder diesen Alters). Je langer die Kinder extrauterin gelebt hatten, desto eher zeigten sie eine positive Reaktion. Bei 27 zum Termin geborenen und sieben fruhgeborenen hypotrophen Kindern wurde der Einfluss einer intrauterinen Wachstumsverzogerung untersucht. 30 dieser Kinder zeigten positive Reaktionen. Die zum Termin geborenen hypotrophen Kinder wurden mit den reifen Neugeborenen verglichen und hatten signifikant weniger positive Reaktionen in der 45sten Woche post conceptionem. Bei den hypotrophen Kindern trat die Reaktion spater auf. Abnorme intrauterine Bedingungen scheinen daher die Vestibularisfunktion zu beeintrachtigen.

Se obtuvieron un total de 56 respuestas positivas. La mayoria de los lactantes a termino AGA respondieron dentro de la 45 semana postconcepcional (60 por cien de los 50 lactantes examinados a esta edad).

Abstract: The headache histories obtained from 214 children were analysed by computer to see whether it was possible to identify and classify migraine, and to distinguish children with psychogenic headache. During headache attacks, most children had no or very few associated symptoms. For classification, 175 patients were divided into four homogeneous groups; the remaining 39 could not be grouped. An overlap between the different groups was found. Psychogenic headache emerged as a clearly definable syndrome, characterised by psychological problems and daily headache for a period of at least one month (10 patients). When the 214 patients were grouped according to the classification of the Headache Classification Committee of the International Headache Society, distinguishing those children with psychogenic headache was no longer possible.

Abstract: The present work deals with the harvesting of Arthrospira platensis (Spirulina) from a diluted culture medium. This cyanobacterium was retained by the European Space Agency as food supply for long term manned spatial missions, and integrated in the MELiSSA project: an artificial microecosystem which supports life in space. Membranes techniques seem to be adapted to efficiency, reliability and safety constraints, even if a well-known limitation is the progressive fouling and permeation flux decrease. Among usual solid/liquid separation processes, Arthrospira harvesting is performed by tangential ultrafiltration (tubular inorganic membrane 50 kD Céram-Inside from Tami, Nyons, France). To ensure a reliable separation step with the best biomass quality, a good comprehension of the ultrafiltration progress and fouling phenomenon is needed, in particular, the link between operating parameters, permeation flux and cleanability. Comparative experiments were made between limiting and critical flux with different suspensions: fresh biomass, stressed biomass and a suspension of Arthrospira platensis enriched with exopolysaccharides.

198. The Sierra de Velasco (northwestern Argentina) an example for polyphase magmatism at the margin of Gondwana

Author: Juana N. Rossi, Alejandro J. Toselli, Hubert Miller, Frank Söllner, and Florencio Gilberto Aceñolaza
Subjects: Gondwana, METAMORPHIC ROCKS, GRANITE TYPES, Magmatism, DEFORMATION AGES, Paleontology, Geología, Geomorphology, SIERRA DE VELASCO, CIENCIAS NATURALES Y EXACTAS, Geology, Ciencias de la Tierra y relacionadas con el Medio Ambiente
Abstract: The Sierra de Velasco is formed of large plutons that are related to each other by intrusive contacts and separated by generally aligned deformation zones. The plutons are composed of calc-alkaline, syn-, late- and post-kinematic granitoids of different ages and intrusion levels. They are grouped in three large batholiths: Aimogasta, Bazán and Patquía. On the northeastern flank, the metamorphic country rock is represented by micaschists, phyllites and quartzites with hornfels (La Cébila Formation), to the north by tonalitic porphyries that in all cases demonstrate a shallow level of the granitoid intrusions. Shape of the plutons, as well as structural characters and grade of deformation indicate that the intrusive sequences began in Ordovician times and culminated in the Carboniferous, with deformation periods during Silurian and Devonian times. © 2007 E. Schweizerbart'sche Verlagsbuchhandlug. La Sierra de Velasco es un extenso afloramiento predominantemente granítico, integrado por plutones calco-alcalinos, sin-, tardío- a post-tectónicos, con edades diferentes y relacionados entre sí tanto a través de fajas de deformación, como por relaciones intrusivas. Los plutones se agrupan en los batolitos: Aimogasta, Bazán, y Patquía. Las rocas metamórficas de caja están representadas por micacitas, filitas y cuarcitas, con corneanas, sobre el flanco nororiental, y pórfiros tonalíticos en el extremo norte de la sierra, que evidencian el emplazamiento somero de los granitos. Las formas de los plutones, así como los caracteres estructurales y grados de deformación, indican que las secuencias graníticas se habrían iniciado en el Ordovícico y culminado en el Carbonífero, con edades de deformación en el Siluro-Devónico.

199. The Mahdist Revolution

Author: Major Robert N. Rossi and Major Robert N. Rossi
Subjects: Mahdi
Abstract: This paper analyzes the Mahdist Revolution in the Sudan from 1881 to 1885. Mohammed Ahmed bin Abdallah proclaimed himself the Mahdi (the expected one or the deliverer in the Islamic faith) and fought the colonial Egyptian government of the Sudan and the British. Britain was drawn into the conflict by its interest in the Suez Canal, its heavy financial investments in Egypt, and its participation in suppressing the Arabi revolt.Mohammed Ahmed successfully defeated the Egyptian and British forces brought against him and established an Islamic state in the Sudan. He succeeded by effectively combining religious, economic, cultural, and military strategy under charismatic leadership.

200. Lower Carboniferous post-orogenic granites in central-eastern Sierra de Velasco, Sierras Pampeanas, Argentina: U–Pb monazite geochronology, geochemistry and Sr–Nd isotopes

Abstract: The central-eastern part of the Sierra de Velasco (Sierras Pampeanas, NW Argentina) is formed by the large Huaco (40 x 30 km) and Sanagasta (25 x 15 km) granite massifs and the small La Chinchilla stock (2 x 2 km). The larger granites intrude into Ordovician metagranitoids and crosscut Devonian (?) mylonitic shear zones, whereas the small stock sharply intrudes into the Huaco granite. The two voluminous granites are biotitic-muscovitic and biotitic porphyritic syeno- to monzogranites. They contain small and rounded tonalitic and quartz-dioritic mafic microgranular enclaves. The small stock is an equigranular, zinnwaldite- and fluorite-bearing monzogranite. The studied granites are silica-rich (SiO2 > 70%), potassium-rich (K2O > 4%), ferroan, alkali-calcic to slightly calk-alkalic, and moderately to weakly peraluminous (A/CNK = 1.06-1.18 Huaco granite; 1.01-1.09 Sanagasta granite; 1.05-1.06 La Chinchilla stock). They have moderate to strong enrichments in several LIL (Li, Rb, Cs) and HFS (Nb, Ta, Y, Th, U) elements, and low Sr, Ba and Eu contents. U-Pb monazite age determinations indicate Lower Carboniferous crystallization ages: 350-358 Ma for the Huaco granite, 352.7 ± 1.4 Ma for the Sanagasta granite and 344.5 ± 1.4 Ma for the La Chinchilla stock. The larger granites have similar eNd values between ?2.1 and ?4.3, whereas the younger stock has higher eNd of ?0.6 to ?1.4, roughly comparable to the values obtained for the Carboniferous San Blas granite (?1.4 to ?1.7), located in the north of the sierra. The Huaco and Sanagasta granites have a mainly crustal source, but with some participation of a more primitive, possibly mantle-derived, component. The main crustal component can be attributed to Ordovician peraluminous metagranitoids. The La Chinchilla stock derives from a more primitive source, suggesting an increase with time in the participation of the primitive component during magma genesis. The studied granites were generated during a post-orogenic period in a within-plate setting, possibly as a response to the collapse of the previous Famatinian orogen, extension of the crust and mantle upwelling. They are part of the group of Middle Devonian-Lower Carboniferous granites of the Sierras Pampeanas. The distribution and U-Pb ages of these granites suggests a northward arc-parallel migration of this mainly post-orogenic magmatism with time. Fil: Grosse, Pablo.
