Vin Santo.  

PubMed

Vin Santo is the typical dessert wine produced in Tuscany, in particular, and in other areas of central and northern Italy, as well as on the Greek island of Santorini. It remains one of the most important "meditation wines", whose glamour starts with its ancient and mysterious origin. Italy is the country with the World's greatest tradition for sweet wine production. In this contest most of the steps in the Vin Santo making process are still linked to old local traditions. This chapter provides an overview of the different styles of Vin Santo produced in Italy together with its marketing. The main factors affecting grapes drying, alcoholic fermentation, maturation in barrels, are also described. So far there have been few scientific studies that have focused on Vin Santo. However, the increasing demand registered in the last few years for this kind of wine, is now greatly stimulating the research aimed to better manage its peculiar production process. PMID:21867892

Ostracodes from the Aptian-Santonian of the Santos, Campos and Esprito Santo basins, Brazil  

NASA Astrophysics Data System (ADS)

The Lower and Upper Cretaceous deposits from the Brazilian marginal basins present a rich and diversified fauna of ostracodes in continental, marine and mixohaline paleoenvironments. While the Cretaceous ostracodes from the northeastern region have already been the subject of many taxonomic and biostratigraphical studies, data from the southeastern basins are still scarce and restricted to the record of a few species. The present study represents a comprehensive contribution to the systematic knowledge of the Aptian-Santonian ostracodes from the Brazilian southeastern marginal basins. A total of 1045 cutting samples were analyzed from 10 wells drilled offshore in Santos, Campos and Esprito Santo basins. Thirty-eight ostracode taxa were recorded from different depositional environments, including the following six new species: Amphicytherura fragilis sp. nov., Brachycythere multidifferentis sp. nov., Fossocytheridea ballentae sp. nov., Fossocytheridea elegans sp. nov., Nigeroloxoconcha itanhaensis sp. nov. and Paracypris eniotmetos sp. nov.

Continuous Mantle Exhumation at the Outer Continental Margin of the Santos, Campos and Esprito Santo Basins, Brazil  

NASA Astrophysics Data System (ADS)

The interpretation of 12,000 km of very deep (PSTM to 16 sec., PSDM to 25 km) 2D seismic sections, coupled with gravimetric and magnetometric modeling line-by-line, and the integration of the results with the regional data bank of Petrobras, all together viewed in terms of the recent tectonic models developed for the rupturing and separation of mega-plates, led to a regional (500,000 km2), first-time ever, 3D-view of the deep structure underlying the prolific sedimentary basins of Santos, Campos and Esprito Santo in southeastern Brazil. The three basins are situated onto a continental margin that narrows gradually, from south to north, from a very wide (Santos), through an intermediate (Campos), and then to a narrow (Esprito Santo) passive margin. The seismic sections shows very well the dual rheological behavior of the continental crust, consisting of a deeper and plastic lower crust (with numerous short and strong reflections that display sub-horizontal ductile flow) and a shallower and brittle upper crust (represented by a mostly transparent and faulted seismic facies topped by the sedimentary sections of the rift and thermal subsidence phases). The crustal structure of the Santos Basin shows a zonation from west to east of alternating bands of NE-SW-trending thin (plastic basement terrains) and thick (resistant basement terrains) stretched continental crust. In vertical section this zonation is displayed as a series of necking zones, leading to a highly irregular, low to moderate crustal taper. Such zonation is less developed in the Campos Basin, where the crustal taper is moderate and regular, and practically non-existent in the Esprito Santo Basin, where the crustal taper is high. The most outstanding crustal feature shared in common by the three basins is the exhumation of mantle between the tip of the hyper-extended continental crust and the tabular-shaped oceanic crust. Although the crustal taper varies significantly from basin to basin their continental crust pinches out invariably on the flanks of exhumed mantle. This gives rise to a remarkable long (900 km along a N-S direction and 600 km in E-W direction), relatively narrow (15 to 70 km wide) and continuous belt of exhumed mantle that marks the passage from continental crust to oceanic crust in all three basins. The Santos, Campos and Esprito Santo Basins thus form a typical magma-poor passive margin. These are in sharp contrast with the adjacent basin to the south, the Pelotas Basin, that in turn is a typical volcanic passive margin displaying a long (1000 km in a N-S direction) and wide (100 to 220 km) belt of seaward-dipping reflectors at its outer margin and no exhumation of the mantle at the continent-ocean boundary.

Bathymetry, Chirp and Deep Crustal Structure of the Santos Basin SO Paulo Ridge Complex (sbspr)  

NASA Astrophysics Data System (ADS)

The SanBa (Santos Basin- Seismic Research experiment) research experiment is a joint project of the Department of Marine Geosciences (IFREMER: Institut Franais de Recherche pour l'Exploitation de la MER, France), the Laboratory of "Oceanic Domain" (Institut Universitaire et Europen de la Mer, France), the Faculdade de Cincias da Universidade de Lisboa (Lattex and CGUL, Portugal), the Universidade de Brasilia (Brazil) and PETROBRAS. Its aim is to test hypotheses that have been proposed such as the existence of failed rift and a micro-block (Moulin et al., GSL submitted) or the presence of exhumed mantle on its south-eastern part (Zalan et al., AAPG 2009). Six wide-angle seismic data were acquired together with coincident deep frequency reflection seismic data during the SanBa cruise in Dec 2010 - Jan. 2011 (total > 850 Nm). Chirp and Bathymetry were also acquired during the cruise. The preliminary results suggest a very thin crust (< 5km) in the center and in the south-eastern part of the SBSPR. Both refraction and reflection data present a clear signal of the Moho in the distalmost part of the study area, which seems to preclude the exhumed mantle hypothesis."

Forbidden Therapies: Santo Daime, Ayahuasca, and the Prohibition of Entheogens in Western Society.  

PubMed

Santo Daime, a Brazilian religion organized around a potent psychoactive beverage called ayahuasca, is now being practiced across Europe and North America. Deeming ayahuasca a dangerous "hallucinogen," most Western governments prosecute people who participate in Santo Daime. On the contrary, members of Santo Daime (called "daimistas") consider ayahuasca a medicinal sacrament (or "entheogen"). Empirical studies corroborate daimistas' claim that entheogens are benign and can be beneficial when employed in controlled contexts. Following from anthropology's goal of rendering different cultural logics as mutually explicable, this article intercedes in a misunderstanding between policies of prohibition and an emergent subculture of entheogenic therapy.

Contact metamorphism in the Los Santos W skarn (NW Spain)  

NASA Astrophysics Data System (ADS)

The intrusion of the Lower Permian Los Santos-Valdelacasa granitoids in the Los Santos area caused contact metamorphism of Later Vendian-Lower Cambrian metasediments. High grade mineral assemblages are confined to a 7 km wide contact aureole. Contact metamorphism was accompanied by intense metasomatism and development of skarns, and it generated the following mineral assemblages: diopside, forsterite, phlogopite (clintonite) and humites and spinel-bearing assemblages or diopside, grossular, vesuvianite wollastonite in the marbles, depending on the bulk rock composition. Cordierite, K-feldspar, andalusite and, locally, sillimanite appear in the metapelitic rocks. Mineral assemblages of marbles and hornfelses indicate pressure conditions ranging from 0.2 to 0.25 GPa and maximum temperatures between 630 and 640 C. 13C and 18O depletions in calcite marbles are consistent with hydrothermal fluid-rock interaction during metamorphism. Calcites are depleted in both 18O (?18O = 12.74) and 13C (?13C = -5.47) relative to dolomite of unmetamorphosed dolostone (?18O = 20.79 and ?13C = -1.52). The ?13C variation can be interpreted in terms of Rayleigh distillation during continuous CO2 fluid removal from the carbonates. The ?18O values reflect hydrothermal exchange with an externally derived fluid. Microthermometric analyses of fluid inclusions from vesuvianite indicate that the fluid was water dominated with minor contents of CO2 (CH4 N2) suggesting a metamorphic origin. Fluorine-bearing minerals such as chondrodite, norbergite and F-rich phlogopite indicate that contact metamorphism was accompanied by fluorine metasomatism. Metasomatism was more intense in the inner-central portion of the contact aureole, where access to fluids was extensive. The irregular geometry of the contact with small aplitic intrusives between the metasediments and the Variscan granitoids probably served as pathways for fluid circulation.

Palaeomagnetic Investigations on Santo Antao, Cape Verde Islands  

NASA Astrophysics Data System (ADS)

Samples from five hitherto fairly unexplored young volcanic islands in the Cape Verde Archipelago have been collected for palaeomagnetic studies. Magnetic results from lava flows in 5 profiles located on the island Santo Anto are reported. The Cape Verde Rise situated over the Mesozoic marine anomalies M2-M16, is the result of a slow eastward movement of the Atlantic oceanic lithosphere relative to a hotspot commencing around 20 Ma ago. The uplifted segment of deformed Jurassic oceanic crust seems to be unrelated to the bulk of the igneous activity, which took place during the Neogene. The oldest outcrops encountered on Santo Anto are deeply weathered basalts with an age of 7.57 +/- 0.56 Ma, whereas the investigated profiles cover a time interval from 2.67 +/- 0.05 Ma to 0.38 +/- 0.05 Ma. Investigation of some basic mineral magnetic properties reveal titanomagnetite composition as a general feature, and a pseudo-single-domain behaviour of all lava flows subjected to hysteresis-experiments are found. Flows of normal polarity characterise the Tarrafal Profile, being confined to the Brunhes Chron by 40Ar/39Ar-datings. Two events of reverse polarity are recorded in the stratigraphic column and appear to represent the Big Lost and Emperor Subchrons. The minimum eruption frequency is estimated to be one flow every 2.5 +/- 2.2 Ka. The Agua Nova Profile is likewise dominated by flows of normal polarity belonging to the Brunhes Chron and further contains a few events of reverse polarity. The relatively complex stratigraphy of accessible flows encountered in the Ribeira Grande Area makes the correlation with the global polarity time-scale tentative. The Escabecada Profile records the transition between the lower part of Matuyama and the upper part of the Gauss Chron, and a minimum eruption frequency is estimated to be one flow every 10 +/- 7.1 Ka for the lower part of this profile. The Ch de Morte Profile consists merely of reverse-polarity lava flows belonging to the Matuyama Chron. A tentative correlation between all 5 profiles has been attempted by the use of both radiometric datings and magnetic polarities. Polarities from the Escabecada and Agua Nova Profiles appear to indicate the existence of short events of fully reversed polarity not registered as subchrons in the global polarity time-scale. The presence of a reversed polarity event within the Brunhes Chron, as recorded by 8 lava flows in the Tarrafal Profile, may suggest that this geomagnetic event is of a more substantial and permanent nature than typically expected for large-amplitude secular variations.

Origin of granite at Cabo de Santo Agostinho, Northeast Brazil  

NASA Astrophysics Data System (ADS)

A 4 km2 exposure of shallowly-emplaced leucogranite on the Atlantic coast at Cabo de Santo Agostinho, 30 km south of Recife, Brazil has been extensively studied chemically and isotopically. Twenty-three major-element analyses indicate that the Cabo granite ranges from peralkaline to peraluminous; Na2O+K2O is very high (7.4 to 10.4 wt.%), with CaO low (0.3%) and MgO vanishing (<0.06%). Microprobe analyses confirm the presence of arfvedsonite (biotite absent), and nearly total absence of plagioclase. The rocks are moderately to highly enriched in LREE (La 45 to 350 times chondritic), with extremely pronounced negative Eu anomalies (Eu/Eu*=0.02 to 0.07). Whole-rock ? 18O is consistent at +8.50.3%.oSMOW A Rb-Sr isochron age of isotopically slightly disturbed samples is 104.81.8 Ma, with initial87Sr/86Sr=0.70840.0011. Sr is depleted (2 20 ppm) but Ba is 200 750 ppm. Crystallization path calculations and petrographic observations suggest that magma formed at a pressure close to 6 kbar but rose to a crustal level equivalent to roughly 1 kbar. Quartz, the liquidus phase at moderate H2O concentrations and pressures above 2 kbar, was resorbed during decompression as the magma moved upwards. Ultimately, quartz and alkali feldspar coprecipitated. Feldspar was not retained in the source rock nor removed early from the fractionating magma. Therefore the strong negative Eu anomaly and low Sr abundance are characteristics inherited from the source. A high H2O concentration necessary for a large degree of melting was lacking, hence the Cabo magma composition must reflect a small degree of partial melting of a rather quartz-rich rock such as a feldspathic arenite. In a pre-drift reconstruction of Gondwanaland, the Cabo granite fits on the southernmost and youngest end of the trend of the Niger-Nigerian igneous centers with which it has close affinity. The Cabo granite occupies the western end of the trace of the ancestral Ascension mantle plume which presumably served as the heat source.

Circulation in the deep canyon at the entrance to Todos Santos Bay, Mxico, Is there a deep net outflow?  

NASA Astrophysics Data System (ADS)

A numerical model was used to investigate the deep circulation in a canyon of Todos Santos Bay, Mxico. The deep canyon current at the entrance of Todos Santos Bay from a numerical model is compared with the annual averaged outflow from observations below 150 m. The model result suggests that this reported outflow is part of an anticyclonic eddy, but more studies are required, both from numerical models and from observations, to know the circulation in that area.

Phylogeography of rabies virus isolated from herbivores and bats in the Esprito Santo State, Brazil.  

PubMed

Rabies is enzootic in the State of Esprito Santo, Brazil. Every year, cattle and horses die from rabies that is transmitted by the vampire bat Desmodus rotundus. This paper describes the spread of the rabies virus by the continuous diffusion model using relaxed random walks with BEAST software. Forty-one (41) sequences of gene G from the rabies virus that was isolated from bats and domestic herbivores from several areas of the state between 2006 and 2010 were analyzed. The phylogenetic tree showed three main clusters as well as two sub-clusters under cluster 2. A spatial analysis showed that three strains of the rabies virus spread independently. In general, central Esprito Santo, which is mountainous, was the area where separation of the virus strains occurred. This physical barrier, however, was overcome at some point in time, as samples from different lineages were found in the same microarea. PMID:23264105

A geophysical view of the Southeastern Brazilian margin at Santos Basin: Insights into rifting evolution  

NASA Astrophysics Data System (ADS)

This study investigates the rifting structures of Santos Basin at the Southeastern Brazilian margin, based on an integrated geophysical approach. Our aim is to constrain the crustal basement topography of central and northern Santos basin, the presence of magmatism and the role of inherited structures in space and time through the rifting processes. We present a new high resolution aeromagnetic dataset, which in correlation with gravity anomalies enables us to interpret the tectonic trends and crustal basement structures. We calculated the magnetic basement depth for the central and northern Santos Basin using power spectrum analysis. The obtained depths range between 2 and 9 kms, and are comparable with results from previous works. From our integrated study, three margin domains could be identified, which display distinct rifting structures and are characterized by important lateral variation along the margin. The proximal domain displays trends and magnetic basement blocks NE-SW oriented, i.e., parallel to inherited onshore crustal basement with an inflexion to E-W oriented trends; the necking domain is characterized by oblique magnetic basement highs and lows (E-W and NW-SE) and a structural trend change. The trends and magnetic basement highs are bounded by NW-SE negative anomalies, interpreted as transfer zones. Oceanwards at the distal domain, the lineaments and transfer zones show a progressive structural inflexion to ENE and E-W, sub-parallel to adjacent South Atlantic Fracture Zones. The observed crustal basement architecture and segmentation suggest the reactivation of pre-rift structures at the proximal margin and the obliquity of rifting relative to them. From the proximal domain oceanwards the structural pattern may reflect the passage from a continental type domain, where lithospheric inheritance controls the deformation, to a distal margin where this influence diminishes and new structural trends are formed. We propose that northern Santos Basin show evidences of an intensely deformed zone, where rift evolved under oblique extension, similar to that observed at transform margin segments.

Outbreak of Hantavirus Pulmonary Syndrome, Los Santos, Panama, 19992000  

PubMed Central

An outbreak of hantavirus pulmonary syndrome occurred in the province of Los Santos, Panama, in late 1999 and early 2000. Eleven cases were identified; 9 were confirmed by serology. Three cases were fatal; however, no confirmed case-patient died. Case-neighborhood serologic surveys resulted in an overall hantavirus antibody prevalence of 13% among household and neighborhood members from the outbreak foci. Epidemiologic investigations did not suggest person-to-person transmission of hantavirus infection. By use of Sin Nombre virus antigen, hantavirus antibodies were detected in Oligoryzomys fulvescens and Zygodontomys brevicauda cherriei. This outbreak resulted in the first documented cases of human hantavirus infections in Central America. PMID:15498167

Cytherellid species (Ostracoda) and their significance to the Late Quaternary events in the Santos Basin, Brazil  

USGS Publications Warehouse

Four autochthonous cytherellid species (Cytherella serratula (BRADY, 1880), C. hermargentina WHATLEY et al. 1998, C. pleistocenica sp. nov. and C. santosensis sp. nov.) have been identified from two offshore cores (44 samples) within the Santos Basin. The distribution of these ostracodes is controlled by local hydrological conditions such as the temperature and, possibly, the oxygen minimum zone (OMZ). However, these factors cannot explain completely the species occurrence in the analysed cores, and relative sea level changes and productivity variation driven by climatic changes are proposed as additional explanations for the faunal distribution pattern. ??

Two new species of Tornidae (Caenogastropoda, Rissooidea) from Esprito Santo, Brazil  

PubMed Central

Abstract Two new species of shallow water Tornidae are found in Esprito Santo state, Brazil, formally described herein. They belong to a complex group of tiny gastropods, in such the taxonomy is very confused. Cyclostremiscus mohicanus sp. n. is characterized by three well-developed spiral, equidistant carinas, working as base of three series of tall, aligned periostracal rods. Episcinia itanhuna sp. n. has as single sculpture a series of pustules in periphery, but the periostracum bears three series of peripheral fringes with irregular rods. The new species are compared with the allies, showing a close relation with Caribbean fauna, but possessing worthy differences. These similarities have raised misidentifications. PMID:23226709

The dynamics of internal tidal waves in Todos Santos Bay, Baja California, during experiment FLOO-2007  

NASA Astrophysics Data System (ADS)

The aim of this work is to describe the characteristics of internal waves in Todos Santos Bay, Baja California (Mexico) from direct measurements made during the international experiment Fluxes Linking the Offshore with the Onshore (FLOO), which was held in August 2007. Time series of temperature and currents were obtained in the study area, placing several submerged moorings with chains of HOBO-V2 sensors and an ADCP. In addition, transects were made using a towed undulating CTD system and chains of thermographs which had a response time of 5 s. These measurements allowed the construction of the scenarios of generation, propagation and disintegration of the internal tide in the Bay. The internal tidal waves are generated by the barotropic tide at the edge of the continental shelf north of the Bay, have wavelengths ~9 km, are distributed in the form of an arc, and travel to the southeast with phase velocity ~20 cm/s . In shallow waters near the coast, tidal waves are refracted and quickly divide into groups of short nonlinear internal waves with amplitudes 15-20 m, periods 5-20 minutes, and wavelengths 50-200 m. Nonlinear internal waves play an important role in the dynamics of Todos Santos Bay, especially in the coastal zone. During partial or total destruction, vertical mixing and sudden changes of stratification take place. This affects the formation of the vertical structure of water density and ocean biological productivity.

212?Allergic Sensitization to Domestic Mites in Santo Domingo, Dominican Republic  

PubMed Central

Background The objective of this study was to determine the prevalence of mites sensitization in Santo Domingo. Methods One hundred consecutive patients (52 males and 48 females, mean age 30.3 years; 468) with asthma and /or allergic rhinoconjunctivitis were skin tested with 9 commercial extracts of mites of the following species: Dermatophagoides pteronyssinus, D. farinae, Blomia tropicalis, B. kulagini, Acarus siro, Lepidoglyphus destructor, Tyrophagus putrescentiae, Glycyphagus domesticus and Chortoglyphus arcuatus. A skin test was considered positive when the wheal was > 3 mm with erythema. Conventional exclusion criteria were used, in order to avoid masking a skin reaction. Results A positive skin test to any of the mites tested was detected in 98% of the patients; Dermatophagoides spp. was positive in 89% of the patients; 15% were exclusively positive to Dermatophagoides spp; 87% reacted to Blomia spp. and 3% were exclusively positive to Blomia tropicalis spp; 80% were sensitized to 3 or more specie. Conclusions The allergy sensitization to domestic mites in Santo Domingo is high. Sensitization to several species is very common. B. tropicalis is an important species in this region. With these results we could extrapolate that immunotherapy with only Dermatophagoides species could not be enough achieve clinical improvement in mite allergic patients. Other species, such as B. tropicalis may be needed.

Microbe-mineral interactions in naturally radioactive beach sands from Espirito Santo, Brazil: experiments on mutagenicity.  

PubMed

Previous studies on naturally radioactive materials suggested that they can have a mutagenic effect on plants (growing in sands in Kerala, South West India), and on bats (dwelling in an abandoned underground mine of primary monazite ore in Namaqualand, Western Cape, South Africa). We hypothesised, based on previous theoretical work, that radioactive sands would not induce mutants in microorganisms over time scales typical of doubling times in the natural environment. The potential of exceptionally monazite (Th)-rich mineral sands collected from the coast of Espirito Santo, Brazil to induce single-point reversion in Escherichia coli cultures (both repair-competent and repair-deficient strains) was tested using the tryptophan reverse mutation assay. The results show that at least on a short-term scale (1-7 days), the monazite-rich sands did not cause an increase in reversion above background. PMID:17361436

Metal concentration in muscle of two species of flatfish from Santos Bay, Southeastern Brazilian coast  

NASA Astrophysics Data System (ADS)

The aim of this study was to investigate metals in muscles of two species of flatfish, using Particle Induced X-ray Emission (PIXE). Specimens were caught monthly throughout the year 2005. Sampling was done at six points in the Santos Bay under different anthropogenic influences. Analysis of 56 samples of muscle showed detectable amounts of Al, As, Pb, Cu, Cr, Fe, Sr, Mn, Hg, Ni, Se and Zn. Except Cu, there were no correlations with the levels of sediment contamination by metals and those found in muscles. Moreover, there were significant differences between juveniles and adults concerning the concentration of Al, Mn and As. According to Brazilian Health Surveillance Agency, some elements detected in the samples of muscle were above of permitted by law for consumption: Hg and Pb (in samples from the internal area), As (from the west side) and Se and Cr (from east side of the bay).

Ethical proceedings against dentists in Esprito Santo for infringements to the code of dental ethics.  

PubMed

Just like any other profession, dentistry requires ethical and moral responsibilities that must be fulfilled, and the duty of every professional is to meet his obligations under the law. In light of the Cdigo de tica Odontolgica (CEO-Code of Dental Ethics), this research aims to expound on the ethical violations committed by dentists in their practice, according to the ethical review process proposed by the Conselho Regional de Odontologia do Estado do Esprito Santo (CRO/ES-Regional Council of Dentistry of the State of Esprito Santo). The study is both retrospective and descriptive, using a quantitative approach. Data collection comprised all the ethical proceedings filed at the CRO/ES, between the years 2000 and 2011. Considering the 529 cases examined, the most frequent reason for infringement was illicit advertising (39.7%), followed by technical error (18.7%), irregular registration (16.8%), patient/professional relationship (11.3%) tax lien foreclosure (6.6%), professional/professional relationship (4.0%), irregular/illegal cover up practice (0.9%), consumer relations (0.8%), failure to provide care (0.6%), false certification (0.4%), and disrespect for authority and colleagues (0.2%). Most (59.2%) of the dental surgeons (DSs) involved were male, 35.5% were between 31 and 40 years of age, 85.8% had graduated over five (5) years prior, and 73.2% were general practitioners. Only 22 (4.2%) cases went to trial, resulting in 8 (36.4%) acquittals and 14 (63.6%) convictions. The most commonly applied penalties were private warning+pecuniary penalty (8 or 57.1%). It was concluded that the CEO must be followed with more discipline, and that professionals should seek information about their duties and obligations under the law, on behalf of patient welfare.

SANTOS - a two-dimensional finite element program for the quasistatic, large deformation, inelastic response of solids  

SciTech Connect

SANTOS is a finite element program designed to compute the quasistatic, large deformation, inelastic response of two-dimensional planar or axisymmetric solids. The code is derived from the transient dynamic code PRONTO 2D. The solution strategy used to compute the equilibrium states is based on a self-adaptive dynamic relaxation solution scheme, which is based on explicit central difference pseudo-time integration and artificial mass proportional damping. The element used in SANTOS is a uniform strain 4-node quadrilateral element with an hourglass control scheme to control the spurious deformation modes. Finite strain constitutive models for many common engineering materials are included. A robust master-slave contact algorithm for modeling sliding contact is implemented. An interface for coupling to an external code is also provided. 43 refs., 22 figs.

Authigenic chlorite as a controlling factor in the exploration of Turonian/Coniacian turbidites in the Santos Basin  

SciTech Connect

Upper Turonian/Coniacian and Campanian turbidites are major targets for petroleum exploration in the Santos Basin, southeastern Brazil. They occur between 140 and 1000 m of present water depth, are buried at about 4500 m, and reach thickness of up to 60 m. The main reservoir facies is composed of unstratified, fine to very fine grained, poorly sorted sandstones, which framework is compositionally immature, including a high proportion of feldspars and volcanic rock fragments. Early coating of grains by authigenic chlorite inhibited pressure solution and quartz cementation in the reservoir. This diagenetic characteristic allowed important preservation of primary porosity (>20%) in the reservoir; nevertheless its permeability never exceeds 30 ml. The study of sedimentary facies and related depositional processes has been conducted to predict the distribution of petroleum-bearing turbidites throughout the Santos Basin; this comprises a major challenge for the petroleum exploration in this important Brazilian exploration frontier.

Integrated quality assessment of sediments from harbour areas in Santos-So Vicente Estuarine System, Southern Brazil  

NASA Astrophysics Data System (ADS)

Santos-So Vicente Estuarine System is a highly populated coastal zone in Brazil and where it is located the major port of Latin America. Historically, port activities, industrial and domestic effluents discharges have constituted the main sources of contaminants to estuarine system. This study aimed to assess the recent status of sediment quality from 5 zones of Port of Santos by applying a lines-of-evidence approach through integrating results of: (1) acute toxicity of whole sediment and chronic toxicity of liquid phases; (2) grain size, organic matter, organic carbon, nitrogen, phosphorus, trace metals, polycyclic aromatic hydrocarbons, linear alkylbenzenes and butyltins; (3) benthic community descriptors. Results revealed a gradient of increasing contamination for metals and organic compounds, alongside with their geochemical carriers. Sediment liquid phases were more toxic compared to whole sediment. Low number of species and individuals indicated the impoverishment of benthic community. The use of site-specific sediment quality guidelines was more appropriate to predict sediment toxicity. The integration of results through Sediment Quality Triad approach and principal component analysis allowed observing the effects of natural stressors and dredging on sediment quality and benthic distribution. Even with recent governmental efforts to control, pollution is still relevant in Port of Santos and a threat to local ecosystems.

Modern sedimentation processes in a wave-dominated coastal embayment: Esprito Santo Bay, southeast Brazil  

NASA Astrophysics Data System (ADS)

Sediment dynamics in wave-dominated coastal embayments are generally controlled by seasonal meteorological conditions, storms having a particularly strong influence. In the present study, such hydrodynamic processes and associated deposits have been investigated in a coastal embayment located along the southeast coast of Brazil, i.e. Esprito Santo Bay, in the winter (June/July) of 2008. The bay has undergone a series of human interventions that have altered the local hydrodynamic processes and, consequently, the sediment transport patterns. Facies distribution and sediment dynamics were examined by acoustic seabed mapping, sediment and core sampling, hydrodynamic measurements and sand transport modelling. The results show that sediment distribution can be described in terms of nearshore and offshore zones. The offshore bay sector is predominantly composed of "palimpsest" lithoclastic medium-coarse sands deposited in the course of the early Holocene transgression that peaked about 5,000 years ago. In the inner bay or nearshore zone (up to depths of 4-8 m), these older transgressive deposits are today overlain by a thin (up to 30-cm-thick) and partly patchy blanket of younger regressive fine sand/muddy fine sands. Both coarse- and fine-grained facies are being reworked during high-energy events (Hs>1.5 m) when fine sediment is resuspended, weak tide-induced drift currents causing the sand patches to be displaced. The coarser sediment, by contrast, is mobilized as bedload to produce wave ripples with spacings of up to 1.2 m. These processes lead to a sharp spatial delimitation between a fine sand/mud facies and a rippled coarse sand facies. The fine sand patches have a relief of about 20-30 cm and reveal a typical internal tempestite depositional sequence. Fair-weather wave-induced sediment transport (Hs<1 m), supported by weak tidal currents, seems to only affect the fine sediment facies. Sediment dynamics in Esprito Santo Bay is thus essentially controlled by wave action during storms, tidal currents playing a very subordinate role. Anthropogenic changes due to the construction of a port at the entrance of the bay have not only produced erosion along the beach, but could also explain the occurrence of sand patches concentrated in the north-eastern part of the bay. Because storm-induced deposits of the type observed in this study have an inherently patchy distribution, this feature needs to be taken into consideration when interpreting the rock record in terms of modern analogues.

Seasonal prevalence and container preferences of Aedes albopictus in Santo Domingo City, Dominican Republic.  

PubMed

The seasonal prevalence and container preferences of Aedes albopictus (Skuse) were studied in the park, Parque Mirador del Norte in Santo Domingo City, Dominican Republic, from January to December 1994. Tire ovitraps were set along a transect through the park and monitored weekly while two larval surveys were conducted in both the park and surrounding houses using standard entomological methodology. No seasonal pattern of oviposition was observed with similar numbers of positive tire traps collected in the wet and dry season. Most of the positive ovitraps were located in the middle of the park. Within ovitraps, Aedes aegypti (L.), Ae. albopictus, Culex corniger (Theobald), Ochlerotatus albonotatus (Coquillett), and Toxorhynchites sp. were collected. The larval surveys found 7 associated mosquito species, including Ae. aegypti, Ae. albopictus, Ochleotatus mediovittatus (Coquillett), Anopheles albimanus (Weidemann), Culex nigripalpus (Theobald), and Culex quinquefasciatus Say. The Ae. albopictus breeding sites were plastic buckets (4), rock holes (3), and Styrofoam lunch containers (3). We suggest that further studies should be conducted to determine its geographic distribution and vector potential in the Dominican Republic. PMID:14714670

Geology and mineralogy of the Santo Nino Ag-Pb-Zn vein, Fresnillo District, Mexico  

SciTech Connect

The Santo Nino Ag-Pb-Zn vein is the major producer of the Fresnillo District, located 750 km NW of Mexico City. It is over 2.4 km long, more than 480 m in vertical extent, more than 2.5 m wide overall, and has average grades of >600 gm/t Ag and <2% combined Pb and Zn. The vein is hosted by a tilted sequence of Cretaceous graywackes, shales and andesitic volcanics and extends upward into a Lower Tertiary conglomerate. Up to 5 separate opening events occurred along the vein, resulting in discontinuous stages of brecciation and crustiform banding. Ore mineral zonation is well developed both vertically and laterally and closely reflects metal and metal ratio distributions. Ore minerals are sphalerite, galena, pyrite, chalcopyrite, arsenopyrite, marcasite, pyrrhotite, acanthite, native silver, and three coexisting solid solution series, pyrargyrite-proustite, polybasite-arsenopolybasite, and tetrahedrite-tennantite in a gangue of quartz, calcite, clay, sericite,and chlorite. A 5-stage paragenetic sequence can be established: 1) pyrite, arsenopyrite, quartz, 2) sphalerite, galena, chalcopyrite, quartz, 3) tetrahedrite, pyrargyrite, polybasite, quartz, 4) acanthite, native silver, calcite, quartz, and 5) calcite. Preliminary microprobe analyses indicate that the Ag-rich solid solution series are Sb-rich in the central and upper portions of the vein and As-rich at deeper levels.

Use of Cathorops spixii as bioindicator of pollution of trace metals in the Santos Bay, Brazil.  

PubMed

In the present study Cathorops spixii, was evaluated as a bioindicator fish for trace metal pollution. Concentrations of cobalt (Co), iron (Fe), selenium (Se) and zinc (Zn) were determined by Instrumental Neutron Activation Analysis in liver. Mercury (Hg) and methyl-mercury (MeHg) were analyzed by Cold Vapor Atomic Absorption Spectrometry in muscles and livers. High concentrations of Co, Fe, Se and Zn were observed in C. spixii from Santos Bay in comparison to fish collected in a non-polluted site in the same Brazilian coast. These trace metal concentrations were out of the permissible levels for human consumption. Although, Hg and MeHg levels were low, the C. spixii could still be used as an effective bioindicator to observe trace metal behaviors in the environment in function of the bioaccumulation process observed mainly by other analyzed trace metals. Thus, the use of this species is strongly recommended to monitor the effects and behavior of trace metal pollution in aquatic ecosystems in Brazil due to its bioaccumulation function. PMID:19404739

[Respiratory symptomatics among patients at primary health clinics in Vitria, Esprito Santo State, Brazil].  

PubMed

The aim of this study was to estimate the rate of positive respiratory symptomatics among patients seeking treatment at primary health clinics in Vitria, Esprito Santo State, Brazil. This cross-sectional study included 603 individuals that answered a questionnaire with socio-demographic data and a question on cough in the previous three weeks. The prevalence ratio was calculated with 5% significance. The proportion of patients with positive respiratory symptoms in the municipality was 4%, varying from 1.6 to 11.7% between regions. The majority (71%) did not report cough as the reason for coming to the health clinic. Variables significantly associated with respiratory symptoms were: shortness of breath (PR = 6.29; 95%CI: 2.22-21.81) and lack of appetite (PR = 2.75; 95%CI: 1.08-6.82). Among patients with respiratory symptoms, cough was the principal reason for seeking treatment. This condition was only associated with two variables, thus demonstrating the need to adopt different strategies to identify these individuals among the daily patient flow in primary health clinics.

Seasonal variation of the upwelling trap in the Todos Santos Bay, Baja California  

NASA Astrophysics Data System (ADS)

Todos Santos Bay is located on the Pacific coast of Baja California, a region characterized by coastal upwelling throughout the year, being more intense in spring and summer. Aquaculture activities are expanding in the bay, so it is important to understand the processes that modulate the water temperature and stratification, given that these in turn affect biological productivity. This work presents an analysis of the seasonal variation of the temperature of the bay and adjacent regions, with satellite data and CTD casts made in quarterly cruises between 2008-2012. It has been observed that, on average, the surface temperature in the bay is warmer than outside, suggesting that upwelled waters that enter the bay are trapped a sufficiently long time to be heated by solar radiation, hence the name upwelling trap. During upwelling events that drive cold waters to the surface in the regions adjacent to the bay, satellite images show that the surface temperature inside the bay can be 4-5 C higher than the surrounding area. This thermal front is strongest in summer when solar radiation is greater. We have studied the vertical structure of the lens of warm water with CTD data, which shows that its depth does not exceed 10 m and the temperature is 3 to 4 C warmer than the water below. Preliminary results on the processes involved in the formation and evolution of the upwelling trap at synoptic to monthly scales will be presented, based on the analysis of sea surface temperature images, winds, and currents in the northwestern entrance of the bay.

Prevalence of liver diseases as referred by people living in the Santos and So Vicente Estuary.  

PubMed

The Santos and So Vicente Estuary has suffered extensively over the years from irregular industrial deposits. The present study aimed to evaluate liver disease prevalence and potential associated risk factors in four of the Estuary's areas (Piles and gua-Fria, Cubato Center, Continental So Vicente, and Guaruj) and a reference area (Bertioga). This study consisted of a cross-sectional study design, in which a questionnaire was used to collect information in 820 households at each of the study areas. The proportion of total liver diseases, hepatitis, cirrhosis, and cancer (liver, biliary tract, and pancreas) per area were estimated. Pearson's chi-square test and two proportion differences test were applied in order to evaluate associations between disease occurrence and areas and to test differences between two proportions, respectively. Single and multiple logistic regression models were applied to assess associations between disease prevalence and the different study areas. Liver disease prevalence was 1.5% among all inhabitants and 1.4% among those without any type of exposure. Among those who reported the presence of liver disease, a higher percentage of the participants that reported hepatitis (27.7%) or other liver disease (48.7%) did not report occupational or alcohol exposures. Hepatitis (77.8%) was the most reported disease, and a statistical association between living in Piles and gua-Fria and the occurrence of hepatitis was observed (Pearson's ? (2): z?=?18.1; p?=?0.001). The consumption of locally-produced groceries (2.88; CI: 1.24-6.70) and water (5.88; CI: 2.24-15.45) were shown to be risk factors for the occurrence of liver disease. Thus, environmental exposure is still a public health problem present in the estuary region. PMID:24870289

Bioclimatic distribution and prevalence maps for Fasciola hepatica in Esprito Santo State, Brazil  

PubMed Central

Background Fasciolosis affects different ruminant species and leads to great economic losses for cattle farmers worldwide. Thus, the current study aimed to evaluate bovine fasciolosis prevalence in the state of Esprito Santo, Brazil, using slaughter maps provided by slaughterhouses and verifying the origin of cattle. Methods A map was created based on analysis of epidemiological data. The ArcGIS/ArcINFO 10.1 software was employed in order to elaborate updated bioclimatic maps that displayed the fasciolosis prevalence within the state per city between 2009 and 2011. Results According to the bioclimatic map it was clear that 52.24% of the states total area comprise regions considered favorable for the development and survival of Fasciola hepatica. According to the data provided by slaughterhouses, the parasite was more frequent in the cities of Atlio Vivcqua, Itapemirim and Anchieta with respective prevalence of 28.41, 25.50 and 24.95%. Although the northern portion of the state is also favorable for the disease maintenance (reaching rates above 90%), several cities presented prevalence of only 0.99 and 1.94% respectively. These findings indicate that climatic and environmental factors only cannot be considered preponderant to fasciolosis occurrence. Regarding the slaughterhouse located in Anchieta city, the higher prevalence was registered in the cities of Jernimo Monteiro, Alegre and Cachoeiro de Itapemirim, with mean prevalence of 1.21, 1.07 and 2.09% respectively. Conclusion Although the present findings suggest a pattern for the prevalence of fasciolosis, records of the cities for the occurrence of the disease usually do not reflect the true origin of animals.

Effects of ayahuasca on psychometric measures of anxiety, panic-like and hopelessness in Santo Daime members.  

PubMed

The use of the hallucinogenic brew ayahuasca, obtained from infusing the shredded stalk of the malpighiaceous plant Banisteriopsis caapi with the leaves of other plants such as Psychotria viridis, is growing in urban centers of Europe, South and North America in the last several decades. Despite this diffusion, little is known about its effects on emotional states. The present study investigated the effects of ayahuasca on psychometric measures of anxiety, panic-like and hopelessness in members of the Santo Daime, an ayahuasca-using religion. Standard questionnaires were used to evaluate state-anxiety (STAI-state), trait-anxiety (STAI-trait), panic-like (ASI-R) and hopelessness (BHS) in participants that ingested ayahuasca for at least 10 consecutive years. The study was done in the Santo Daime church, where the questionnaires were administered 1h after the ingestion of the brew, in a double-blind, placebo-controlled procedure. While under the acute effects of ayahuasca, participants scored lower on the scales for panic and hopelessness related states. Ayahuasca ingestion did not modify state- or trait-anxiety. The results are discussed in terms of the possible use of ayahuasca in alleviating signs of hopelessness and panic-like related symptoms. PMID:17532158

Sand fly vectors (Diptera, Psychodidae) of American visceral leishmaniasis areas in the Atlantic Forest, State of Esprito Santo, southeastern Brazil.  

PubMed

The aim of this study was to evaluate the sand fly fauna of American visceral leishmaniasis (AVL) endemic areas within the Central Atlantic Forest Biodiversity Corridor, State of Esprito Santo, southeastern Brazil. The sand fly captures were performed between January, 1989 and December, 2003 in localities where autochthonous cases of AVL were recorded, as well as in their boundary areas. Sand flies were collected from surrounding houses and domestic animal shelters using two to five CDC automatic light traps, and manual captures were also performed using mouth aspirators in one illuminated Shannon trap during the first four hours of the night. We used cladistic analysis to determine the geographic relationships among the collected sand fly species as well as the index species for the occurrence of other sand flies. A total of 62,469 sand flies belonging to 17 species and eight genera was collected in 164 localities from nine municipalities with AVL records. The richness (S=17) and diversity (H=0.971) of sand flies were lower than in conservation areas and similar to modified environments in the Atlantic Forest of Esprito Santo. Lutzomyia longipalpis was identified in 79 localities. The cladistic analysis identified Evandromyia lenti as the index species for Lutzomyia longipalpis. The latter seems to be the main vector of AVL in the Central Atlantic Forest Biodiversity Corridor due to its high abundance and distribution matching the disease occurrence. Therefore, Evandromyia lenti may be used as an index species for the occurrence of Lutzomyia longipalpis. PMID:22548541

Apatite Fission-Track Analysis of the Middle Jurassic Todos Santos Formation from Chiapas, Mexico.  

NASA Astrophysics Data System (ADS)

The Sierra de Chiapas (SCH), located in the south of Mexico, is a complex geological province that can be divided on four different lithological or tectonic areas: (1) the Chiapas Massif Complex (CMC); (2) the Central Depression; (3) the Strike-slip Fault Province, and (4) the Chiapas Fold-and-thrust Belt. The CMC mostly consists of Permian granitoids and meta-granitoids, and represents the basement of the SCH. During the Jurassic period red beds and salt were deposited on this territory, related to the main pulse of rifting and opening of the Gulf of Mexico. Most of the Cretaceous stratigraphy contains limestones and dolomites deposited on a marine platform setting during the postrift stage of the Gulf of Mexico rift. During the Cenozoic Era took place the major clastic sedimentation along the SCH. According the published low-temperature geochronology data (Witt et al., 2012), SCH has three main phases of thermo-tectonic history: (1) slow exhumation between 35 and 25 Ma, that affected mainly the basement (CMC) and is probably related to the migration of the Chorts block; (2) fast exhumation during the Middle-Late Miocene caused by strike-slip deformation that affects almost all Chiapas territory; (3) period of rapid cooling from 6 to 5 Ma, that affects the Chiapas Fold-and-thrust Belt, coincident with the landward migration of the Caribbean-North America plate boundaries. The two last events were the most significant on the formation of the present-day topography of the SCH. However, the stratigraphy of the SCH shows traces of the existence of earlier tectonic events. This study presents preliminary results of apatite fission-track (AFT) dating of sandstones from the Todos Santos Formation (Middle Jurassic). The analyses are performed with in situ uranium determination using LA-ICP-MS (e.g., Hasebe et al., 2004). The AFT data indicate that this Formation has suffered high-grade diagenesis (probably over 150 C) and the obtained cooling ages, about 70-60 Ma, correspond to a Late Cretaceous event. This tectonic event is contemporaneous with a startup of the Laramide Orogeny occurred in North America. The constructed time-temperature paths show the rapid cooling during the Middle-Late Miocene (15-10 Ma), like other published data. References: Hasebe et al.

Molecular Characterization of Noroviruses and HBGA from Infected Quilombola Children in Espirito Santo State, Brazil  

PubMed Central

Noroviruses (NoV) are the main etiological agents of gastroenteritis outbreaks worldwide and susceptibility to NoV infection has been related to the histo-blood group antigen (HBGA). This study aimed to determine the prevalence of NoV strains and to evaluate the HBGA phenotype and genotype of children from semi-isolated Quilombola communities, descendents of black slaves in Brazil. A total of 397 children up to eleven years old, with and without diarrhea, from Quilombola Communities in the Espirito Santo State, Brazil, were investigated for the presence of NoV from August 2007 to September 2009. Feces were collected from all the children, and blood from the NoV positive children. NoV was screened by reverse transcription-PCR with primers for the RNA-dependent RNA polymerase region; genogroup was determined by PCR with primers for the C and D regions and genotyped by sequencing. HBGA phenotype was performed by gel-spinning and FUT2 and FUT3 were analyzed by PCR or sequencing analysis. NoV were detected in 9.2% (12/131) of diarrheic and 1.5% (4/266) of non-diarrheic children (p<0.05, Fishers exact test). GI and GII genogroups were present in 12.5% and 87.5% of the samples, respectively. The following genotypes were characterized: GII.4 (25%), GII.12 (25%), GII.6 (12.5%) and GI.1 (6.3%), GI.3 (12.5%) and GI.4 (6.3%). Children infected with NoV showed the A (n?=?6), O (n?=?6), and B (n?=?2) HBGA phenotypes, and 13 of them were classified as secretors (Se) and one as a non secretor (se). Mutations of Se40, 171,216,357,428,739,960 were found for the FUT2 gene and mutations of Le59, 202, 314 for the FUT3 gene. The only se child was infected by NoV GI, whereas the Se children were indiscriminately infected by GI or GII. This study showed rates of NoV infection in symptomatic and asymptomatic Quilombola children consistent with other studies. However, children under 12 months were seven times more affected than those between 1 and 5 years old. GII.12 was as frequent as GII.4 and GI.1 and GI.4 were described for the first time in Brazil. Owing to the small number of cases studied, no clear pattern of susceptibility and/or HBGA resistance could be inferred. PMID:23894453

Biodiversity and structure of the polychaete fauna from soft bottoms of Bahia Todos Santos, Baja California, Mexico  

NASA Astrophysics Data System (ADS)

This paper describes diversity patterns of the polychaete fauna in Bah?a Todos Santos (Pacific Ocean, Baja California, Mexico). Thirty-nine stations were sampled in October 1994. Measurements of depth, temperature, salinity, dissolved oxygen, organic content and sediment particle size were made. Polychaetes constituted 64% of all invertebrate macrofauna, with 13,757 specimens in 44 families representing 203 species. The best represented families were Spionidae, Capitellidae, Paraonidae, Cirratulidae, Maldanidae, Ampharetidae and Nephtyidae. Bah?a Todos Santos presented high species richness (species/station); values varied between 6 (near the harbor) and 67 species (next to Estero Punta Banda). Higher species richness values (48 species to 67/station) were located in the southern section of the bay. Abundances (individuals/station) were generally high (120-1434) except for some coastal stations. Nearly one-third of the stations presented H' values higher than 4.00. Diversity ( H') values ranged from 2.06 to 4.80; higher diversity values were found in the southern section of the bay. The stress-predictability modeling characterized approximately 70% of stations as presenting favorable and stable conditions. Pearson and Bray-Curtis coefficients separated stations in relation to their sediment particle size, depth and location in the bay. Principal component analysis determined that organic matter content, percentage of silt-clay, and water depth accounted for 95% of the total variance for all environmental factors measured. Correspondence analysis distinguished three groups of species: Group A species with an extensive distribution throughout the bay and relatively high abundances, Group B species abundant in the shallow areas, especially near the harbor, and Group C species present in the area of the submarine canyon. Non-metric multidimensional scaling analysis separated five groups of stations, depending on depth, grain size and location in the bay. Our results show that Bah?a Todos Santos is a favorable environment for polychaete development, their distribution being strongly related to sediment characteristics. The dominant trophic group corresponds to deposit-feeders (91 species).

Low Sensitivity of NS1 Protein Tests Evidenced during a Dengue Type 2 Virus Outbreak in Santos, Brazil, in 2010  

PubMed Central

In 2010, a large outbreak of dengue occurred in Santos, Brazil. The detection of the NS1 antigen was used for diagnosis in addition to the detection of IgG, IgM, and RNA. A large number of NS1 false-negative results were obtained. A total of 379 RNA-positive samples were selected for thorough evaluation. NS1 was reactive in 37.7% of cases. Most of the cases were characterized as a secondary infection by dengue 2 virus. Sequencing of NS1 positive and negative isolates did not reveal any mutation that could justify the diagnostic failure. Use of existing NS1 tests in the Brazilian population may present a low negative predictive value, and they should be used with caution, preferentially after performing a validation with samples freshly obtained during the ongoing epidemic.

10Be dating of river terraces of Santo Domingo river, on Southeastern flank of the Mrida Andes, Venezuela: Tectonic and climatic implications  

NASA Astrophysics Data System (ADS)

In this study, we discuss the first cosmogenic 10Be dating of river terraces located in the lower reaches of the Santo Domingo river (Southeastern flank of the Mrida Andes, Western Venezuela). The geomorphic observations and dating allowed the restoration of the temporal evolution of incision rate, which was analysed in terms of tectonic, climatic and geomorphic processes. The long-term incision rate in the area has been constantly around 1.1 mm/a over the last 70 ka. Taking into account the geologic and geomorphologic setting, this value can be converted into the Late Pleistocene uplift rate of the Southeastern flank of the Mrida Andes. Our results show that the process of terraces formation in the lower reaches of the Santo Domingo river occurred at a higher frequency (103-104 years) than a glacial/interglacial cycle (104-105 years). According to the global and local climate curve, these terraces were abandoned during warm to cold transitions.

Comparative sediment quality assessment in different littoral ecosystems from Spain (Gulf of Cadiz) and Brazil (Santos and So Vicente estuarine system).  

PubMed

The goal of this work was to establish comparisons among environmental degradation in different areas from Southern Spain (Gulf of Cdiz) and Brazil (Santos and So Vicente estuary), by using principal component analyses (PCA) to integrate sediment toxicity (amphipods mortality) and chemical-physical data (Zn, Cd, Pb, Cu, Ni, Co, V, PCBs, PAHs concentrations, OC and fines contents). The results of PCA extraction of Spanish data showed that Bay of Cdiz, CA-1 did not present contamination or degradation; CA-2 exhibited contamination by PCBs, however it was not related to the amphipods mortality. Ra of Huelva was the most impacted site, showing contamination caused principally by hydrocarbons, in HV-1 and HV-2, but heavy metals were also important contaminants at HV-1, HV-2 and HV-3. Algeciras Bay was considered as not degraded in GR-3 and -4, but in GR-3' high contamination by PAHs was found. In the Brazilian area, the most degraded sediments were found in the stations situated at the inner parts of the estuary (SSV-2, SSV-3, and SSV-4), followed by SSV-6, which is close to the Submarine Sewage Outfall of Santos - SSOS. Sediments from SSV-1 and SSV-5 did not present chemical contamination, organic contamination or significant amphipod mortality. The results of this investigation showed that both countries present environmental degradation related to PAHs: in Spain, at Ra of Huelva and Gudarranque river's estuary areas; and in Brasil, in the internal portion of the Santos and So Vicente estuary. The same situation is found for heavy metals, since all of the identified metals are related to toxicity in the studied areas, with few exceptions (V for both Brazil and Spain, and Cd and Co for Brazilian areas). The contamination by PCBs is more serious for Santos and So Vicente estuary than for the investigated areas in Gulf of Cdiz, where such compound did not relate to the toxicity. PMID:17175025

Evolution of the Phreatomagmatic Cova de Paul Eruption, Santo Antao, Cape Verde Islands: Links Between Eruption Development and Crater Growth  

NASA Astrophysics Data System (ADS)

Episodes of phreatomagmatic explosive activity that excavate large deep craters occur at high-elevation vents on many oceanic island volcanoes. The water driving these explosions is sourced from freshwater aquifers within the volcanic edifices, whose location and other characteristics will influence crater growth and final geometry. Here we describe phreatomagmatic deposits from the single eruption that formed the large Cova de Paul crater on the island of Santo Antao, Cape Verde Islands. These deposits, emplaced after an initial Strombolian phase of activity, record wide fluctuations in the intensity of phreatomagmatic explosivity. The largest explosions produced low-temperature, indurated lithic-rich phreatomagmatic ignimbrites and surge deposits; these occur as isolated and often erosive-based units in more distal areas but are interbedded in proximal outcrops with airfall to mixed fall and flow breccia and ash beds containing varying proportions of lithic and juvenile clasts, pointing to a series of climactic explosions within an extended period of milder phreatomagmatic explosive activity. We find that whereas the lithic clasts in the mixed units can be matched with the varied rock units in the exposed crater walls, the ignimbrite and surge units also contain hydrothermally altered clasts that appear to have originated from deeper in the volcanic edifice. They imply that during the climactic explosions the crater was excavated to several hundred meters depth below the surface. The phreatomagmatic explosive phase of the CDPC eruption was initiated by shattering of the chilled margins of the eruptive conduit, which had formed during the early Strombolian activity. The remains of these chilled margins form a distinctive bed of large flow-banded angular sub-glassy juvenile clasts that separates the Strombolian deposits from the later phreatomagmatic deposits. At this point water inflow from pressurized aquifers into the conduit attained a critical coolant input ratio prompting the onset of the phreatomagmatic explosions (Tarff and Day 2013). Only rare small angular sub-glassy clasts are present in the rest of the eruptive sequence, suggesting that the chilled margins never re-established. Instead, we propose that subsequent variations in the intensity of phreatomagmatic activity were controlled by fluctuations in water flow to the conduit as the crater was excavated to deeper levels and different aquifers were tapped and depleted. The CDPC deposits can be compared with older phreatomagmatic ignimbrites in other ocean islands, where the source vents have been eroded. Tarff, R. W. and Day, S. J. (2013).

Mass-transport deposits controlling fault propagation, reactivation and structural decoupling on continental margins (Esprito Santo Basin, SE Brazil)  

NASA Astrophysics Data System (ADS)

This work uses high-quality 3D seismic data to assess the importance of mass-transport deposits (MTDs) as markers of fault propagation. We mapped three distinct MTDs and several fault families on the continental slope of Esprito Santo, SE Brazil. Fault mapping was based on seismic attributes such as seismic coherence and structural smoothing, and was further completed using ant tracking algorithms. Genetically related fault families were analysed in terms of their throw-depth (t-z) and throw-distance (t-x) gradient curves. A key result in this paper is that vertical fault propagation can be hindered by MTDs, as demonstrated for Eocene to Early Miocene faults in parts of the study area. Throw-depth variations in faults affected by MTDs are associated with: a) lithologic controls resulting from the presence of MTDs, b) local fault segmentation and c) reactivation by dip linkage. Based on their orientation and degree of interaction with MTDs, interpreted faults can be classified as decoupled and non-decoupled. Importantly, faults decoupled by MTDs have quasi-elliptical t-x profiles and show smaller cumulative throw values and fault propagation rates when compared to their non-decoupled counterparts. Recurrent MTDs can therefore be used as markers to estimate structural decoupling between distinct fault families.

Environmental assessment of dredged sediment in the major Latin American seaport (Santos, So Paulo-Brazil): an integrated approach.  

PubMed

This work offers an environmental assessment of a dredged sediment disposal area in Santos bay, situated on the central coast of the So Paulo State, Brazil. Sediment quality was evaluated through physicochemical analysis and toxicity tests of sediments collected in the disposal site and adjacent area. The physicochemical characterization of the sediments involved grain size distribution, concentrations of polycyclic aromatic hydrocarbons (PAHs), chlorinated and aromatic hydrocarbons, polychlorinated biphenyls (PCBs), pesticides, phthalates, metals and nutrients. Acute and chronic toxicity tests were employed, using amphipods (Tiburonella viscana) and sea urchins (Lythechinus variegatus), respectively. Results revealed toxicity by all the methods applied here, suggesting that the area of disposal of dredged material is significantly altered with respect to sediment quality and probably capable of generating deleterious effects on the local biota. Aiming to elucidate the association between the distinct environmental variables and the biological effects measured in laboratory, Factor Analysis was performed. Results revealed that despite most contaminant concentrations were found below the limits established by Brazilian legislation, biological effects were related to metals (chronic toxicity) and organic compounds (acute toxicity). The application of multivariate analysis proved to be particularly useful to assess and interpret the results in an integrated way, particularly due to the large number of parameters analyzed in environmental assessments, and should be applied in future studies.

Risk factors to incidental leptospirosis and its role on the reproduction of ewes and goats of Esprito Santo state, Brazil.  

PubMed

Ovine and caprine stockbreeding have been gaining attention in developing countries as an attractive investment. On these animals, infectious diseases of the reproductive tract, such as leptospirosis, can compromise the production leading to economic losses. The present study aimed to determine the risk factors associated with incidental leptospirosis and its influence on the reproductive parameters of ewes and goats of Esprito Santo state, Brazil. A total of 737 animals distributed on 24 herds/flocks were studied, and an overall prevalence of 10.9% seroreactive animals was observed. Serogroup Icterohaemorrhagiae was the most frequent in goats (97.0%) as well as in ewes (78.3%). Regarding risk factors related to leptospirosis, the presence of waterholes and the semi-intensive breeding system were the most important associated to seroreactivity. Besides, there was an observed association between seroreactivity and reproductive failures (P?

Weapons of mass destruction preparedness and response for the XIV Pan-American Games, Santo Domingo, 2003.  

PubMed

The Pan-American Games are considered to be the fourth most important international athletic event in the world. Hosted by the city of Santo Domingo, Dominican Republic, the XIV Pan-American Games lasted from 11-17 August 2003. In preparation for the Games, the Security Directorate developed and deployed a Weapons of Mass Destruction (WMD) Unit. For operational support, two strike teams (Alpha and Bravo) were active at any given time. Each team consisted of five members including a team leader, field physician, explosive ordinance disposal (EOD) officer, and two tactical officers. Three hospitals-two military and one civilian--were designated as primary medical centers for the event. With the assistance of the WMD Unit, emergency department staff were trained in the medical management of a WMD event, response protocols for WMD were created, and special decontamination areas were designated. Syndromic surveillance was performed by means of direct communications between the hospitals and units, as well as use of an electronic, Web-based surveillance tool. PMID:17076426

Rovearinids (stemless crinoids) in the Albian carbonates of the offshore Santos Basin, southeastern Brazil: stratigraphic, palaeobiogeographic and palaeoceanographic significance  

NASA Astrophysics Data System (ADS)

Microfacies analysis of marine carbonates cored by Petrobras well 1-SPS-6 in the offshore Santos Basin (southeastern Brazil) has revealed a remarkable fossil assemblage of calpionellids (colomiellids), favusellids, hedbergellids, globigerinelloidids, buliminids, radiolarians, inoceramid prisms, roveacrinids, and saccocomids(?) preserved in lower Albian calcimudstones-wackestones of the lower part of the Guaruj Formation. This assemblage represents an allochtonous accumulation in a deep neritic to shallow bathyal hypoxic environment. Besides 'saccocomid-like' sections, the only determinable sections of roveacrinids are thecal plates of Poecilocrinus dispandus elongatus Peck, 1943. This species was previously only known from the Weno Formation of Texas. The Brazilian material extends its records farther south from at least the lower Albian, which then represents the earliest occurrence of this peculiar family in the South Atlantic region. Taking into account their Albian global distribution and the location of their oldest representative (Hauterivian near Alicante, Spain), the Roveacrinidae dispersed westward throughout all of Cretaceous Tethys. The Tethyan origin of Roveacrinidae is further evidence that, during late Aptian-Albian times, the northern South Atlantic (north of the Walvis-So Paulo Ridge) was supplied by a Tethyan water mass.

Salt roller growth as a controlling factors of the Albian rafts on Esprito Santo Basin, SE Brazil.  

NASA Astrophysics Data System (ADS)

The SE Brazil continental margin is dominated by continental-slope embankment, incision of submarine channel system and significant mass-gravitational processes, with salt tectonics playing a significant role in upper-crust deformation. It is known to comprise a margin rich in oil and gas, in which raft tectonics plays an important role in their migration and accumulation. A combination of 3D pre-stack and post-stack time-migrated (PSTM) data was used to interpret the evolution of the Albian rafts in Esprito Santo Basin, SE Brazil was used in this work to: a) investigate the impact of continuing halokinesis in raft movement and, b) critically assess the parameters considered to control raft tectonics. In the study area Albian rafts, which are laterally constrained by salt rollers that were reactivated during the Late Cretaceous-Cenozoic, are seen to be ramped over triangular salt structures, and rotated by growing salt pillows. As a result, we observe complex compartmentalization styles in the rafts, with three main types of faults being recognised in four distinct rafts: a) rollover faults formed axially to large N-S rafts, b) radial faults to segments of rafts that record torsion and enhanced downslope movement, c) reactivated crestal and keystone faults formed on the flanks of growing salt diapirs onto which rafts are ramped upon. The space between the rafts was also analysed and quantified and show to be influenced by the weight of the sediments overburden. This work shows that slope gradient and overburden thickness had little control on raft segmentation. We interpret these data as a proof that underlying salt was a primary control on raft tectonics in the study area, overriding the effect of overburden thickness and variable slope gradients on the rafts' internal compartmentalisation. This study will show different styles of compartmentalization observed in Albian rafts from SE Brazil.

A critical comparison of different approaches to sediment-quality assessments in the santos estuarine system in Brazil.  

PubMed

This study focuses on the discussion of different lines of evidence (LoEs) applied to a sediment-quality assessment that considered the following: chemical concentrations of metals; polycyclic aromatic hydrocarbons (PAHs) in estuarine waters, sediments, and oysters (native and caged Crassostrea brasiliana); PAHs in semipermeable membrane devices (SPMDs); simultaneously extracted metals-acid volatile sulfides (SEM-AVS); benthic community assessment (the exploratory benthic index and the relative benthic index); chronic toxicity tests with the sea urchin Lytechinus variegatus; and bioaccumulation models. Significantly contaminated sediments from the Santos Estuarine System and the consequent toxicity of tested organisms were measured. Caged oysters presented bioaccumulation rates ?2,500% of total PAH content and 200% of metal content when compared with control organisms from an uncontaminated area. SPMD results presented the same bioaccumulation pattern as caged oysters but at lower concentrations. Benthic communities presented some alterations, and there was a predominance of tolerant species in the inner part of the estuary. According to the SEM-AVS approach, metals should be assumed to be nonbioavailable, but experiments with transplanted C. brasiliana showed metal bioaccumulation, particularly in the cases of chromium, copper, mercury, and zinc. The weight-of-evidence approach was applied to compare and harmonize LoEs commonly used in sediment-quality assessments and to then classify estuary environments according to both their potential for having adverse effects on the biota and their possible ecological risks. All of the results of these approaches (except for SEM-AVS) were found to complement each other. PMID:25398222

Seismic Site Characterization through Joint Modeling of Complementary Data Functionals, with Applications to Santo Domingo, Dominican Republic  

NASA Astrophysics Data System (ADS)

New approaches suggest that it may be possible to determine ground shaking during earthquakes through low-cost, non-invasive seismic surveys that make use of ambient noise, and that the results can be used for 'shake-casting' to produce scenarios for the purposes of urban planning, improving community resilience, and emergency response. We will present a strategy for determining seismic 'site characterization' through joint modeling of and horizontal to vertical spectral ratios (HVSR) and surface wave dispersion, determined via spatial autocorrelation (SPAC), refraction microtremor (ReMi), and/or multi-channel analysis of surface waves (MASW). Fitting of data functionals by synthetics is driven by global optimization and the models are assessed quantitatively. The products of this approach are shear wave velocity profiles for the shallow subsurface, accompanied by posterior probability distributions and parameter correlation matrices that allow for the assessment of model reliability. Optimization strategies for solving nonlinear problems in geophysics have several advantages over linearized inversions. Jointly fitting dispersion curves and HVSR functionals via global optimization allows us to characterize the space of possible models, assess model reliability, identify parts of the 'best-fit' model that are poorly constrained, and guide us toward new data that might improve constraints on the model. Tools such as the posterior probability distribution and the parameter correlation matrix allow us to assess the relative contribution of both types of data to model constraints and how to choose the optimal weights between data types. The joint modeling technique is applied to data acquired in an NSF-funded Pan-American Advanced Studies Institute in Santo Domingo, Dominican Republic, entitled 'New Frontiers in Geophysical Research: Bringing New Tools and Techniques to Bear on Earthquake Hazard Analysis and Mitigation', as a proof-of-concept survey in a highly built-up urban environment.

Comparing progress toward the millennium development goal for under-five mortality in Len and Cuatro Santos, Nicaragua, 19902008  

PubMed Central

Background Social inequality in child survival hampers the achievement of Millennium Development Goal 4 (MDG4). Monitoring under-five mortality in different social strata may contribute to public health policies that strive to reduce social inequalities. This population-based study examines the trends, causes, and social inequality of mortality before the age of five years in rural and urban areas in Nicaragua. Methods The study was conducted in one rural (Cuatro Santos) and one urban/rural area (Len) based on data from Health and Demographic Surveillance Systems. We analyzed live births from 1990 to 2005 in the urban/rural area and from 1990 to 2008 in the rural area. The annual average rate reduction (AARR) and social under-five mortality inequality were calculated using the education level of the mother as a proxy for socio-economic position. Causes of child death were based on systematic interviews (verbal autopsy). Results Under-five mortality in all areas is declining at a rate sufficient to achieve MDG4 by 2015. Urban Len showed greater reduction (AARR?=?8.5%) in mortality and inequality than rural Len (AARR?=?4.5%) or Cuatro Santos (AARR?=?5.4%). Social inequality in mortality had increased in rural Len and no improvement in survival was observed among mothers who had not completed primary school. However, the poor and remote rural area Cuatro Santos was on track to reach MDG4 with equitable child survival. Most of the deaths in both areas were due to neonatal conditions and infectious diseases. Conclusions All rural and urban areas in Nicaragua included in this study were on track to reach MDG4, but social stratification in child survival showed different patterns; unfavorable patterns with increasing inequity in the peri-urban rural zone and a more equitable development in the urban as well as the poor and remote rural area. An equitable progress in child survival may also be accelerated in very poor settings. PMID:24428933

Spatial distribution and concentration assessment of total petroleum hydrocarbons in the intertidal zone surface sediment of Todos os Santos Bay, Brazil.  

PubMed

The primary objective of this study was to investigate the concentrations and spatial distribution of the total petroleum hydrocarbons (TPHs) in the intertidal zone surface sediment of Todos os Santos Bay, Brazil, to assess the distribution and degree of contamination by TPHs, measure the level of TPH degradation in the surface sediment, and identify the organic matter sources. The surface sediment used in this study was collected in 50 stations, and TPHs, isoprenoid alkanes (pristane and phytane), and unresolved complex mixture (UCM) were analyzed by gas chromatography with a flame ionization detector. The total concentrations ranged from 0.22 to 40,101?gg(-1) dry weight and showed a strong correlation with the total organic carbon (TOC) content. The highest TPH concentrations were observed in samples from the mangrove sediments of a river located near a petroleum refinery. Compared with other studies in the world, the TPH concentrations in the intertidal surface sediment of Todos os Santos Bay were below average in certain stations and above average in others. An analysis of the magnitude of UCM (0.11 to 17,323?gg(-1) dry weight) and the ratios nC17/Pr and nC18/Ph suggest that an advanced state of oil weathering, which indicates previous contamination. The molar C/N ratios varied between 5 and 43, which indicate organic matter with a mixed origin comprising marine and continental contributions. PMID:24100798

Integration of the PSI technique and conventional ground-based methods for landslide characterization and monitoring: the case study of Santo Stefano d'Aveto; Northern Apennines, Italy  

NASA Astrophysics Data System (ADS)

Santo Stefano village is located in the Northern Apennines (Italy) and is built up on an ancient landslide, defined as a complex phenomenon that is an earth rotational slide evolving into a flow. The landslide has an extension of 1,3 km2 and a volume of about 10 million of m3. The landslide can be defined as active and according to Cruden & Varnes (1996) nomenclature the velocity range from very slow to extremely slow. The landslide poses and high risk to the buildings and infrastructures causing extensive direct damages. The Santo Stefano d'Aveto village is located inside a glacial valley made mainly of ophliotic rocks, sandstones and marls and filled with glacial deposits. The landslide occurred in the glacial deposits composed of debris in a sandy-clayey matrix. Santo Stefano d'Aveto landslide has been monitored through radar interferometry, in particular with the PS-InSAR technique (Ferretti et al., 2001) and through ground-based instruments such as inclinometers and piezometers. The PS-InSAR analysis has been performed using ascending SAR scenes and descending SAR scenes from ERS-1/-2 (1992-2001), and ascending and descending SAR scenes from ENVISAT (2002-2008). All the datasets have been processed in the advanced mode APSA that means for each PS has been provided deformation time series relative to a reference date (zero). The target points within the Santo Stefano landslide have a high density. In general for all the analysed datasets it has been observed a decrease of velocity from upslope portion to the downslope one of the landslide. The maximum velocity recorded in the ERS dataset is around 38 mm/y, while the maximum velocity recorded in the ENVISAT dataset is around 20 mm/y. The APSA analysis has provided information about the temporal evolution of target points. Both the majority of ERS and ENVISAT time series have shown a seasonal trend related to the variation of the water table level, which rises during rainfall season and decreases during dry season. The time series analysis show that the landslide deformation pattern is strongly controlled by the pore water pressure condition as demonstrated by the piezometric measurements. As usual an increase of water pressure condition led to a decrease of shear strength of the soil causing an increase of movement. Six inclinometric instruments have been installed in 2001 and measurements have been acquired until 2006. A comparison between the deformation measured by the PS techniques and the inclinometric acquisitions has been performed examining the velocity measurements along the same line of sight. In particular in order to perform the comparison, the displacements of the inclinometers, taken along the maximum slope angle direction have been plotted along the line of sight of the satellite. The results show that the displacements measured by the two different type of techniques are consistent. The PSI analysis performed has contributed to a more in depth investigation of the phenomenon, in particular the PS measurements and geomorphologic interpretation have allowed to redefine better the boundaries of landslide and the state of activity while the time series analysis has allowed to better understand the deformation pattern and its relations with the causes of the landslide itself. Once the relationship between actual displacements vectors (measured by in-situ instrumenation) and l.o.s. components is known, the APSA analysis can provide a much larger dataset on ground movement allowing a better modelling of the surface displacements field.

Comment to Santos et al., "Hyper-IgD and periodic fever syndrome: A new MVK mutation (p.R277G) associated with a severe phenotype".  

PubMed

We performed molecular modeling analysis onto a novel mutation in the gene MVK, described by Santos et al., found to be causative of a severe form of Hyper-IgD/Mevalonate Kinase Deficiency. The mutation p.R277G, in our analysis, lowers the binding affinity for some enzyme's substrates. Interestingly, we found that p.R277G mutation inhibits binding of Isopentenyl Pyrophosphate (IPP) (binding free energy=0kcal/mol), one of isoprenoids responsible for feedback-inhibition of MVK. IPP is known to be an activator of a specific class of T-cells and we can hypothesize that increased levels of this metabolite generate an aberrant immune system response. Indeed other experiments are needed to verify this hypothesis; however, this work demonstrates usefulness of molecular modeling in generating novel pathogenic hypothesis. PMID:25620160

Seismic and experimental evidence for thin-skinned horizontal shortening by convergent radial gliding on evaporites, deep-water Santos Basin, Brazil  

SciTech Connect

Thin-skinned gravitational gliding of sediments above a detachment layer of salt or shale is common on passive margins. Changes in surface slope result in a domain of extension upslope and a domain of contraction downslope. Contractional domains tend to occur under present-day deep water and are thus now well understood. In the deep-water Santos Basin, Brazil, a contractional domain contains a suite of salt-cored structures. Angular folds (chevron and box folds), as well as concentric folds, are common in the upper part of the Aptian evaporite sequence, which appears to comprise alternating layers. In general, angular and concentric folds form by flexural slip during shortening of mechanically layered sequences. Their occurrence in the Santos Basin is evidence in favor of horizontal contraction. The lower part of the Aptian evaporite sequence appears to be mostly rock salt. It has been squeezed has been thickened or even repeated across thrust faults and ramp anticlines. An overlying sequence of open-marine sediments has been condensed or eroded over anticlines but forms local depocenters. These depocenters are asymmetric (of foreland style) next to isolated thrusts but symmetric in synclines or between thrusts of opposite vergence. The structural styles have been reproduced in physical models, properly scaled for gravitational forces, in which salt is represented by silicone putty and sediments are represented by sand. The models were shortened horizontally by a screw jack. The experiments illustrate the importance of horizontal contraction and syntectonic sedimentation in shaping salt-cored structures. They have been used to establish criteria that may diagnostic of contraction.

Endemic and threatened tetrapods in the restingas of the biodiversity corridors of Serra do Mar and of the Central da Mata Atlntica in eastern Brazil.  

PubMed

Biodiversity corridors comprise a mosaic of land uses connecting fragments of natural forest across a landscape. Two such corridors have been established along the eastern coast of Brazil: the Serra do Mar and the Central da Mata Atlntica corridors, along which most of the coastal plains are restinga areas. In this study, we analyze the present status of the endemic and endangered terrestrial vertebrates of both corridors. We sampled 10 restingas in both corridors, recording species of amphibians, reptiles, birds, and mammals. Some restingas harbor a relatively large number of endemic species,and two main regions of endemism can be identified along the restingas of both corridors: the coastal restingas from northern Espirito Santo State to southern Bahia State (between Linhares, ES, and Tarancoso, BA), and the coastal region between the restingas of Maric and Jurubatiba, Rio de Janeiro State. Six species of terrestrial vertebrates considered threatened with extinction are found in the restingas of Serra do Mar and Central da Mata Atlntica biodiversity corridors (Liolaemus lutzae, Formicivora littoralis, Mimus gilvus, Schistochlamys melanopis, and Trinomys eliasi). The region located between the restinga of Maric and that of Jurubatiba is of special relevance for the conservation of vertebrate species of the restingas of the corridors because a considerable number of threatened species of terrestrial vertebrates are found there. We strongly recommend efforts to develop checklists of threatened faunas for the States of Espirito Santo and Bahia. PMID:16025914

Episodes of hazardous phreatomagmatic explosive activity, including Surtseyan activity, occur within otherwise less dangerous effusive to mildly explosive magmatic eruptions at high-elevation vents on many oceanic island volcanoes. The water driving these explosions is sourced from freshwater aquifers within the volcanic edifices. Understanding volcanic and geophysical precursors to, and mechanisms of, the (frequently abrupt) transitions to explosive activity is required as a basis for effective warning and mitigation of the resulting hazards. Here we describe near-vent deposits around the large Cova de Pal crater on the island of Santo Anto, Cape Verde Islands, which provide some insights into a transition from mild magmatic to violently explosive phreatomagmatic activity in one such eruption. This pre-historic but well-preserved crater formed in a single eruption that produced extensive low-temperature, lithic-rich phreatomagmatic pyroclastic flows and surge deposits; these are interbedded in proximal outcrops with airfall breccia and ash beds containing varying proportions of lithic and juvenile clasts, pointing to a series of climactic explosions within an extended period of milder explosive activity of broadly Surtseyan type. Prior to the transition to phreatomagmatic activity, the eruption had been characterized by mild Strombolian activity that produced scoria and spatter deposits of broadly tephritic composition. The Strombolian deposits contain a distinct population of strongly banded, low-vesicularity angular clasts with strongly prolate vesicles and a notably glassy appearance. These became markedly larger and more abundant just below the transition to the phreatomagmatic deposits. Comparisons of these clasts with the Strombolian scoria suggest that they are fragments of flow-banded chilled margins from the walls of the eruptive conduit. Thermal shattering of these margins to produce the angular glassy clasts may record the onset of groundwater flow into the conduit, leading to the phreatomagmatic explosive phase of the eruption. Fragmentation of the conduit wall and ingress of groundwater would likely have been accompanied by seismic swarms consisting of high-frequency fracture events and episodes of harmonic tremor, pointing to a potential geophysical signature of the onset of phreatomagmatic explosive activity in comparable future eruptions on Santo Anto and other oceanic islands.

Chilled margin fragmentation as a trigger for transition from Strombolian to phreatomagmatic explosive activity at Cova de Paul Crater, Santo Antao, Cape Verde Islands  

NASA Astrophysics Data System (ADS)

Sudden transitions from effusive or mildly explosive eruptions to violent phreatomagmatic explosive activity can occur at high-elevation vents on oceanic island volcanoes. Here, we describe near-vent deposits around the large Cova de Paul crater on Santo Antao, Cape Verde Islands, which provide insights into the transition from Strombolian magmatic to violently explosive phreatomagmatic activity during one such eruption. The Strombolian deposits change from welded spatter to bedded clinkery scoria to angular blocky scoria, and contain a distinct population of strongly banded, low-vesicularity angular sub-glassy clasts with strongly prolate vesicles. These sub-glassy clasts also form a discrete layer of larger blocks at the transition to the overlying phreatomagmatic deposits. They are compositionally identical to the Strombolian scoria and are interpreted to be fragments of flow-banded chilled margins from the walls of the eruptive conduit. The layer of large sub-glassy blocks records disintegration and expulsion of the chilled margins at the transition to phreatomagmatic activity. We interpret the sequence from spatter through clinkery scoria to blocky scoria as recording an increase in groundwater inflow into the conduit from pressurised aquifers, but at coolant input ratios below those required for explosions. The shattering of the chilled margins to produce the bed of large sub-glassy blocks appears to have allowed a much greater water flow into the conduit, leading to the phreatomagmatic explosive phase of the eruption.

Evolutionary escape from the climate dilemma. Comment on "Climate change governance, cooperation and self-organization" by Pacheco, Vasconcelos and Santos  

NASA Astrophysics Data System (ADS)

Jorge M. Pacheco, Vtor V. Vasconcelos and Francisco C. Santos take stock of a growing body of research they have produced in recent years, with the aim of shedding light on whether bottom-up agreements can suffice in promoting the high levels of cooperation needed to avert dangerous climate change [1]. The current state of affairs leave little reason for optimism, given the steady rise in CO2 emissions [2]. The UNFCCC approach to seeking universal participation has thus been called into question, both by some policy makers and by academics who have established pessimistic theoretical predictions concerning the limited ability of international environmental agreements to improve upon what nation states would do in the absence of an agreement. Game theorists have predicted that self-enforcing agreements are likely to comprise only a handful of countries committing to unambitious emission abatement targets [3]. Clearly, this is incompatible with stabilizing CO2 concentrations at levels that significantly constrain the likelihood of dangerous climate change. The question than arises as to whether we can deliver on ambitious abatement targets by leveraging on unilateral action by countries or other sub- or supra-national entities (e.g. cities or blocs). This has recently been analyzed in game-theoretic contexts [4,5], as well as in the governance literature [6], with more optimistic predictions compared to traditional models focusing on overarching agreements.

Migratory flows and foraging habitat selection by shorebirds along the northeastern coast of Brazil: The case of Baa de Todos os Santos  

NASA Astrophysics Data System (ADS)

Large numbers of Nearctic shorebirds migrate and winter along the coast of northeastern Brazil, but there is little information on their migratory flows, foraging ecology, and on the structure of the species assemblages that they form with resident shorebirds. We studied these issues on intertidal flats of Baa de Todos os Santos (Bahia), the second largest bay in Brazil. During a full year cycle we carried out weekly bird counts in an intertidal area of 280 ha divided in sectors, where we also measured environmental parameters. The analyses of weekly counts resulted in a detailed phenology of use of the area by shorebirds. Five species were resident and ten were Nearctic migrants. Several of the latter had clear peaks in numbers in March and October, revealing the use of the bay as a stopover during both the north-bound and south-bound migration flows. A canonical correspondence analysis of the relationship between environmental parameters and bird numbers indicated that the foraging bird assemblage could be divided into five main groups, occupying distinct ecological gradients in the study area. The most important factors driving this structure were invertebrate prey abundance, percentage of fine sediments, area of mangrove cover and distance to channels. Our findings imply that maintenance of the diversity of intertidal habitats in this bay is crucial to satisfy the particular habitat requirements of resident and migrant shorebirds using the northeastern coastal regions of Brazil.

Probing The Buried Remains of The Todos los Santos, City of San Salvador in Hoping Island with Shallow Subsurface Geophysics Method  

NASA Astrophysics Data System (ADS)

The study in ancient sites with GPR is widely documented over several decades. This non-invasive geophysical method provides a rapid measure for anthropogenic objects and therefore serves as a guide for possible excavation for the next stage of archaeological surveys. City of San Salvador, which is a Dutch colonial city consisted of fortress, hospitals and churches in 17 century, is located in the Hoping Island in Keelung, Taiwan. The fortress and its affiliated structures were abandoned and left collapsing since the mid-17th century. Some relics of the fortress wall were still remained until the early 20th century but the fast development projects in the island has caused the relics demolished or buried under building or road pavements. Many wells and bones have been found around the area belong to over three hundred years ago. As a consequence, the government initiated a new excavation project at the parking lot where the ancient convent of Todos los Santos is believed since 2011 in order to find the remains of the convent in city of San Salvador. Meanwhile we have surveyed with GPR to help guiding the excavation location. In this case, we surveyed with wide-angle-refraction/reflection (WARR) of GPR as well as common-offset array, to compensate the defect of traditional common-offset of lack of longitudinal resolution with velocity profile, and the combination of velocity profile and common-offset data helped distinguish the signals from other noises and further located the position of subsurface structures. After data analysis and numerical modeling of the buried materials, we have located the possible remains of walls of the convent or other structures around 0.9 to 1.3 meters in depth that can offer useful information to better plan the archaeological excavations.

Entomological characterization and natural infection of anophelines in an area of the Atlantic Forest with autochthonous malaria cases in mountainous region of Esprito Santo State, Brazil.  

PubMed

Autochthonous malaria cases in the state of Esprito Santo, Brazil, are distributed in mountainous regions surrounded by the Atlantic Forest. While some aspects of this disease are unclear, detection of possible vector species can help to elucidate epidemiological uncertainties. Entomological and natural infection studies were carried out using anophelines (Diptera: Culicidae) captured in the municipality of Santa Tereza, ES. Monthly captures were made from March 2004 to February 2006. CDC-CO2 traps were used from dusk (6:00 P.M.) to dawn (6:00 A.M.) to capture anophelines in the following habitats: near the houses, in open areas (at ground level) and inside, and at the margins of the forest (canopy and ground level). Shannon light traps were also used at the same locations of the CDC-CO2 traps. A total of 2,290 anophelines within 10 species were captured. The relative frequency of Anopheles (Kerteszia) cruzii Dyar & Knab / A.(K.) homunculus Komp was the highest, with the majority captured in CDC-CO2 traps installed in the forest canopy. The main species captured in Shannon traps was A.(Nyssorhynchus) strodei Root. The largest number of anophelines was captured from July to September and from 6:00 P.M. to 10:00 P.M. Anopheles (K.) cruzii is the probable vector for malaria transmission inside or near the Atlantic Forest fragments, but the role of other species cannot be ignored, as 53% of the sampled anophelines belonged to the subgenus Nyssorhynchus. The natural infection of A. cruzii, A. parvus (Chagas) and A. galvaoi Causey, Deane & Deane by Plasmodium vivax detected by PCR from DNA extracted from their thoraxes supports this view.

Petrography, geochemistry, and depositional setting of the San Pedro and Santo Tomas coal zones: anomalous algae-rich coals in the middle part of the Claiborne Group (Eocene) of Webb County, Texas  

USGS Publications Warehouse

Two coal zones, the San Pedro and the overlying Santo Tomas, are presented for nearly 35 km in outcrop, surface and underground mines, and shallow drill holes along the strike of the middle part of the Claiborne Group (Eocene) in Webb County, Texas. A sandstone-dominated interval of 25 to 35 m separates the two coal zones, which range up to 3 m in thickness. The coal-bearing portion of the middle Claiborne Group in the Rio Grande area represents a fining-upward transition from sandstone-dominated, marine-influenced, lower delta plain depositional environments to more inland, mudstone-rich, predominantly freshwater deltaic settings. The less variable nature of the Santo Tomas coal zone reflects its origin in the upper part of an interlobe basin that received only minor clastic influx. Petrographic attributes of the nonbanded coals indicate that they formed subaqueously in fresh to possibly brackish waters. Petrographic study of polished blocks indicates that approximately 10% of the nonbanded coal from both coal zones is composed of green algae fructifications. -from Authors

Comment on Structural controls on a carbon dioxide-driven mud volcano field in the Northern Apennines (Pieve Santo Stefano, Italy): Relations with pre-existing steep discontinuities and seismicity  

NASA Astrophysics Data System (ADS)

Bonini (2009, Structural controls on a carbon dioxide-driven mud volcano field in the Northern Apennines (Pieve Santo Stefano, Italy): relations with pre-existing steep discontinuities and seismicity. Journal of Structural Geology 31, 44-54) presents a 2D mechanical analysis to infer the failure conditions responsible for the seismicity distribution during an M w = 4.6 seismic sequence nucleating during 2001 in the Northern Apennines. In my view the mechanical analysis presented in this paper has some weakness or is not well constrained, in particular: 1) the assumption of a dip angle of 50, is not consistent with the activated structures; 2) the P f = ?3 condition, difficult to be attained along a cohesionless fault dipping at 50; 3) the isotropic stress state, i.e. ?2 = ?3, that is not consistent with the active or recent stress field in the area.

Fruit flies (Diptera, Tephritidae) and their associations with native host plants in a remnant area of the highly endangered Atlantic Rain Forest in the State of Esprito Santo, Brazil.  

PubMed

The results presented in this paper refer to a host survey, lasting approximately three and a half years (February 2003-July 2006), undertaken in the Vale do Rio Doce Natural Reserve, a remnant area of the highly endangered Atlantic Rain Forest located in Linhares County, State of Esprito Santo, Brazil. A total of 330 fruit samples were collected from native plants, representing 248 species and 51 plant families. Myrtaceae was the most diverse family with 54 sampled species. Twenty-eight plant species, from ten families, are hosts of ten Anastrepha species and of Ceratitis capitata (Wiedemann). Among 33 associations between host plants and fruit flies, 20 constitute new records, including the records of host plants for A. fumipennis Lima and A. nascimentoi Zucchi. The findings were discussed in the light of their implications for rain forest conservation efforts and the study of evolutionary relationships between fruit flies and their hosts. PMID:18439337

Influence of pre-salt alignments in post-Aptian magmatism in the Cabo Frio High and its surroundings, Santos and Campos basins, SE Brazil: An example of non-plume-related magmatism  

NASA Astrophysics Data System (ADS)

This study, based on interpretations of 2D and 3D seismic data, onshore satellite data, and offshore seismic mapping and well data, addresses the geological evolution of Late Cretaceous and Early Tertiary magmatism in the offshore Cabo Frio area, at the border between the Santos and Campos basins, SE Brazil. The analysis of the available data set suggests an alternative genesis for this magmatism, different from the classic mantle plume model. Seismic mapping of the main feeder dikes reveals a predominant SE-NW orientation, coincident with the alignment of the Cruzeiro do Sul deformation zone, in which the Cabo Frio High is included. This observation is coherent with the characteristics of the major onshore Precambrian strike-slip faults, which were reactivated during the Cenozoic. The largest offshore volumes of magmatic rocks occur intercalated in the sedimentary section and at the intersections of two fault alignments: a SE-NW, strike-slip fault trend and a SW-NE, normal fault trend, similar to the onshore alkaline bodies of the Poos de Caldas-Cabo Frio alignment. The possibly reactivated faults (mainly SE-NW transfer faults) could have cut through the whole lithosphere, reached the asthenosphere, and caused partial melting simply by pressure release.

DaCHS in this sense works as glue between data produced by the data providers and the standard protocols and formats defined by the VO. This paper discusses central elements of the design of the package and gives two case studies of how VO protocols are implemented using DaCHS' concepts.

The potentially dangerous asteroid 2012 DA14  

NASA Astrophysics Data System (ADS)

We present computing methods that allow us to study the behaviour of the dynamically interesting potentially dangerous asteroid 2012 DA14. Using the freely available ORBFIT software, we can follow the orbit of the asteroid backward and forward in the future, searching for close approaches to the Earth that might lead to possible impacts. The possible impact orbit for 2026 is computed. We show that it should be possible to recover asteroid 2012 DA14, mainly in 2013 February. It is highly unlikely that asteroid 2012 DA14 will hit any geosynchronous satellites during its close approach on 2013 February 15.

Origin of the DA and non-DA white dwarf stars  

NASA Technical Reports Server (NTRS)

Various proposals for the bifurcation of the white dwarf cooling sequence are reviewed. 'Primordial' theories, in which the basic bifurcation of the white dwarf sequence is rooted in events predating the white dwarf stage of stellar evolution, are discussed, along with the competing 'mixing' theories in which processes occurring during the white dwarf stage are responsible for the existence of DA or non-DA stars. A new proposal is suggested, representing a two-channel scenario. In the DA channel, some process reduces the hydrogen layer mass to the value of less than 10 to the -7th. The non-DA channel is similar to that in the primordial scenario. These considerations suggest that some mechanism operates in both channels to reduce the thickness of the outermost layer of the white dwarf. It is also noted that accretion from the interstellar medium has little to do with whether a particular white dwarf becomes a DA or a non-DA star.

O contedo desse texto surgiu de uma apresentao de mesmo ttulo que fiz na XXXI Reunio Anual da Sociedade Astronmica Brasileira (SAB) em 2005. Esse tema foi inspirado originalmente pela minha participao no "2nd UIPAP International Conference on Women in Physics" realizado entre 23 e 25 de maio de 2005 no Rio de Janeiro. Essa uma conferncia internacional que acontece de trs em trs anos, sendo que a primeira ocorreu em 2002 na cidade de Paris, Frana. Participei dessa conferncia como membro da delegao da Sociedade Brasileira de Fsica e um dos trabalhos que apresentei versava sobre a situao das mulheres na Astronomia brasileira, cujos resultados principais discorro a seguir. A situao das astrnomas, baseada nos dados dos scios da SAB coletados no final de 2004, comparada com a das fsicas brasileiras e tambm com as nossas colegas americanas. Os dados identificam ainda uma maior evaso da carreira por parte das mulheres do que os homens. Alguns dos possveis motivos da evaso so discutidos, como o desejo de constituir famlia e/ou isolamento. Resultados um tanto preocupantes com relao distribuio de bolsas de produtividade do CNPq tambm so apresentados. As principais discusses e estratgias recomendadas nesse congresso so mencionadas de forma resumida ao final.

Geochemistry and origin of the early Mesoproterozoic mangerite-charnockite-rapakivi granite association of the Serra da Providncia suite and associated gabbros, central-eastern Rondnia, SW Amazonian Craton, Brazil  

NASA Astrophysics Data System (ADS)

The Serra da Providncia suite (SPS) is constituted of quartz mangerite-charnockite-rapakivi granite and coeval mafic rocks, intruded during the 1.60-1.53 Ga interval into Paleoproterozoic metamorphic basement (Jamari Complex) in the Juruena-Rondnia geochronologic province, SW Amazonian Craton. In this region the Serra da Providncia suite consists of two batholiths and several small plutons represented by syeno-monzogranites and igneous quartz mangerite and charnockites. The Serra da Providncia granites are ferroan, calc-alkalic to alkali-calcic and characterized by high Na2O + K2O, Rb, Zr, Y, Nb, Ta, Ce, Zn, Ga, and REE (except for Eu), moderate Ba, and low Sr, MgO, and CaO. Ga/Al, Y/Nb, FeOT/(FeOT + MgO) and K2O/Na2O ratios are high and Sr/Ba and Rb/Ba are low and are geochemically similar to typical A2-subtype granites. The SPS charnockites and quartz mangerites display values of FeOT, MgO, CaO, Ba, Rb, Sr, Nb/Ta and Zr/Hf similar to the SPS A-type granites. The occurrence of magnetite as an accessory phase and the high FeOT/(FeOT + MgO) in granites, charnockites and quartz mangerites suggest crystallization from a relatively oxidized magma and also explain the occurrence of titanite as a primary phase in these granites, similar to those reported in several localities of the Amazonian Craton. The parental magma of the mafic rocks of the SPS probably had mainly enriched sources and resulted from melting of heterogeneous mantle reservoirs with coherent chemical characteristics. Trace elements data indicate subduction-modified mantle sources for the mafic rocks that are in agreement with the post-collisional character of this magmatism. A large set of whole-rock Sm-Nd isotope data (Bettencourt et al., 1999; Scandolara, 2006; Santos et al., 2008 and this work) demonstrate that granites, charnockites and quartz mangerites of the study area are the product of magmas derived from interaction between enriched mantle derived magmas (in very subordinate proportions) and recycled crust in larger proportion. The source region is dominated by Paleoproterozoic material, but several samples yield Archaean model ages that are the first evidence for such ancient source materials in the SW Amazonian Craton. The Serra da Providncia suite was emplaced during the post-collisional stage of the Juruena-Jamari arc and Madeirinha orogeny (Scandolara et al., 2011), and post-dates the collision between the Tapajs (Tapajs-Parima geochronological province, Par, Brazil) and Bolvia (palaeocontinent which precedes Sunss geochronological province) blocks. Its geochemical and structural features are coincident with those recognized in post-collisional granitoids. Geochemical data suggest that complex processes which involved crustal melting, fractional crystallization, magma mixing and, in some extent, crustal assimilation were responsible for the magmatism of the Serra da Providncia suite. The magmas that constitute the Serra da Providncia suite resulted from varying degrees of partial melting of a compositionally heterogeneous source. The nature of the source and the degree of melting exerted a significant control over compositional variation in some of the parental magmas which were also affected by subsequent fractional crystallization and mingling processes. Internal variations in composition observed in several bodies can be the result of incremental amalgamation of different magma pulses that varied mainly in the degree of partial melting.

The Real Code of Leonardo da Vinci  

PubMed Central

Leonardo da Vinci was born in Italy. Among the researchers and scientists, he is favourably known for his remarkable efforts in scientific work. His investigations of atherosclerosis judiciously combine three separate fields of research. In 1506, he finished his masterpiece, painting of Mona Lisa. A careful clinical examination of the famous painting reveals a yellow irregular leather-like spot at the inner end of the left upper eyelid and a soft bumpy well-defined swelling of the dorsum of the right hand beneath the index finger about 3 cm long. This is probably the first case of familial hypercholesterolemia (FH). The FH code of Leonardo da Vinci was given immense consideration by scientists like Carl Muller, who described the xanthomas tuberosum and angina pectoris. On the contrary, Akira Endo searched for microbial metabolites that would inhibit HMG-CoA reductase, the rate-limiting enzyme in the synthesis of cholesterol and finally, Michael Brown and Joseph Goldstein published a remarkable series of elegant and insightful papers in the 70s and 80s. They established that the cellular uptake of low-density lipoprotein (LDL) essentially requires the LDL receptor. In conclusion: this was the real Code of Leonardo da Vinci. PMID:19924278

A computational theory of da Vinci stereopsis.  

PubMed

In binocular vision, occlusion of one object by another gives rise to monocular occlusionsregions visible only in one eye. Although binocular disparities cannot be computed for these regions, monocular occlusions can be precisely localized in depth and can induce the perception of illusory occluding surfaces. The phenomenon of depth perception from monocular occlusions, known as da Vinci stereopsis, is intriguing, but its mechanisms are not well understood. We first propose a theory of the mechanisms underlying da Vinci stereopsis that is based on the psychophysical and computational literature on monocular occlusions. It postulates, among other principles, that monocular areas are detected explicitly, and depth from occlusions is calculated based on constraints imposed by occlusion geometry. Next, we describe a biologically inspired computational model based on this theory that successfully reconstructs depth in a large range of stimuli and produces results similar to those described in the psychophysical literature. These results demonstrate that the proposed neural architecture could underpin da Vinci stereopsis and other stereoscopic percepts. PMID:24914063

Qual o Papel da Escola e da Mdia na Obteno dos Conhecimentos Astronmicos?  

NASA Astrophysics Data System (ADS)

amplamente reconhecido que as pessoas em geral tm grande fascnio e interesse pela Astronomia. Por outro lado, o contedo dessa rea includo no ensino formal est longe de ser abrangente e suficiente para suprir a demanda. Esse interesse permite aperfeioar a divulgao e o ensino no formal de Astronomia atravs da mdia aliando a adequao do contedo expectativa das pessoas. A reforma do Currculo Bsico da Escola Pblica da maioria dos Estados brasileiros tem introduzido Astronomia desde a pr-escola at o Ensino Mdio. Num estudo realizado com 1180 alunos do Ensino Mdio de seis escolas estaduais, revelou-se atravs da aplicao de um formulrio contendo questes que abordavam conhecimentos bsicos em Astronomia, como foram adquiridos tais conhecimentos e infra-estrutura da escola. Para 66,1% dos entrevistados o professor j fez alguma apresentao a respeito de Astronomia. O presente estudo revelou tambm que 54,4% dos alunos entrevistados adquiriram seus conhecimentos astronmicos na escola, 18,4% atravs da televiso e 27,1% afirmaram que seus conhecimentos foram obtidos atravs de outros tipos de mdia (internet, livros didticos, filmes e revistas). Embora o estudo revele claramente que h certo equilbrio no meio em que os alunos obtiveram seus conhecimentos astronmicos, a mdia busca no somente sua difuso, mas a disponibilizao desse conhecimento de maneira correta, que s vezes, no atingido, apresentando conceitos sem fundamentao e incorretos. Por outro lado, no dia-a-dia escolar, comum encontrar professores que vm para as aulas com concepes prvias, que podem diferir substancialmente das idias a serem ensinadas, dificultando o aprendizado de futuros conceitos cientficos. Uma avaliao criteriosa, avaliando as dificuldades dos professores em determinar o sentido correto dos conceitos e observando a metodologia que utilizam no ensino, poder proporcionar uma melhor compreenso sobre as concepes alternativas, presentes no ensino de Astronomia.

DA-6034 Induces [Ca2+]i Increase in Epithelial Cells  

PubMed Central

DA-6034, a eupatilin derivative of flavonoid, has shown potent effects on the protection of gastric mucosa and induced the increases in fluid and glycoprotein secretion in human and rat corneal and conjunctival cells, suggesting that it might be considered as a drug for the treatment of dry eye. However, whether DA-6034 induces Ca2+ signaling and its underlying mechanism in epithelial cells are not known. In the present study, we investigated the mechanism for actions of DA-6034 in Ca2+ signaling pathways of the epithelial cells (conjunctival and corneal cells) from human donor eyes and mouse salivary gland epithelial cells. DA-6034 activated Ca2+-activated Cl- channels (CaCCs) and increased intracellular calcium concentrations ([Ca2+]i) in primary cultured human conjunctival cells. DA-6034 also increased [Ca2+]i in mouse salivary gland cells and human corneal epithelial cells. [Ca2+]i increase of DA-6034 was dependent on the Ca2+ entry from extracellular and Ca2+ release from internal Ca2+ stores. Interestingly, these effects of DA-6034 were related to ryanodine receptors (RyRs) but not phospholipase C/inositol 1,4,5-triphosphate (IP3) pathway and lysosomal Ca2+ stores. These results suggest that DA-6034 induces Ca2+ signaling via extracellular Ca2+ entry and RyRs-sensitive Ca2+ release from internal Ca2+ stores in epithelial cells. PMID:24757369

Berengario da Carpi: a pioneer in neurotraumatology.  

PubMed

Berengario da Carpi was one of the most famous physicians of the 16th century, a recognized master of anatomy and surgery, an emblematic "Renaissance man" who combined his medical experience and engineering knowledge to design new surgical instruments, and effectively used the arts of writing and drawing to describe state-of-the-art medicine and provide illustrations of anatomical structures. His greatest contribution to medicine was to write the most important work on craniocerebral surgery of the 16th century, the Tractatus de Fractura Calvae sive Cranei (Treatise on Fractures of the Calvaria or Cranium), in which he described an entire set of surgical instruments to be used for cranial operations to treat head traumas that became a reference for later generations of physicians. This was a systematic treatise covering the mechanisms, classification, and medical and surgical treatment of head traumas, and can be considered a milestone in the history of neurotraumatology.

Leonardo da Vinci's contributions to neuroscience.  

PubMed

Leonardo da Vinci (1452-1519) made far-reaching contributions to many areas of science, technology and art. Leonardo's pioneering research into the brain led him to discoveries in neuroanatomy (such as those of the frontal sinus and meningeal vessels) and neurophysiology (he was the first to pith a frog). His injection of hot wax into the brain of an ox provided a cast of the ventricles, and represents the first known use of a solidifying medium to define the shape and size of an internal body structure. Leonardo developed an original, mechanistic model of sensory physiology. He undertook his research with the broad goal of providing physical explanations of how the brain processes visual and other sensory input, and integrates that information via the soul.

Metal Lines in DA White Dwarfs  

NASA Astrophysics Data System (ADS)

We report Keck telescope HIRES echelle observations of DA white dwarfs in a continuation of an extensive search for metals. These spectra are supplemented with new JHK magnitudes that are used to determine improved atmospheric parameters. Of the DA white dwarfs not in binary or common proper motion systems, about 25% show Ca II lines. For these, Ca abundances are determined from comparison with theoretical equivalent widths from model atmosphere calculations; in a few cases we also obtain Mg, Fe, Si, and Al abundances. If Ca is not observed, we generally determine very stringent upper limits. We compare the data to predictions of previously published models involving the accretion/diffusion of interstellar matter and of comets. The derived abundances are not obviously compatible with the predictions of either model, which up to now could only be tested with traces of metals in helium-rich white dwarfs. By modifying certain assumptions in the published interstellar accretion model we are able to match the distribution of the elements in the white dwarf atmospheres, but, even so, tests of other expectations from this scenario are less successful. Because comet accretion appears unlikely to be the primary cause of the DAZ phenomenon, the data suggest that no more than about 20% of F-type main-sequence stars are accompanied by Oort-like comet clouds. This represents the first observational estimate of this fraction. A plausible alternative to the accretion of cometary or interstellar matter is disruption and accretion of asteroidal material, a model first suggested in 1990 to explain excess near-infrared emission from the DAZ G29-38. An asteroidal debris model to account for the general DAZ phenomenon does not presently disagree with the HIRES data, but neither is there any compelling evidence in support of such a model. The HIRES data indicate that in close red dwarf/white dwarf binaries not known to be cataclysmic variables there is, nonetheless, significant mass transfer, perhaps in the form of a wind flowing off the red dwarf. As a by-product we find from the kinematics of GD 165 a likely age of more than 2 Gyr for its probable brown dwarf companion GD 165B. This paper is based in part on observations obtained at the Calar Alto Observatory of the Deutsch-Spanisches Astronomisches Zentrum and at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California, and NASA. The Observatory was made possible by the generous financial suppport of the W. M. Keck Foundation. We have made use of the SIMBAD database at CDS.

MIGRATION FROM OPC-DA TO OPC-UA  

E-print Network

The OPC-DA specification of OPC has been a highly successful interoperability standard for process automation since 1996, allowing communications between any compliant components regardless of vendor. CERN has a reliance on OPC-DA Server implementations from various 3rd party vendors which provide a standard interface to their hardware. The OPC foundation finalized the OPC-UA specification and OPC-UA implementations are now starting to gather momentum. This paper gives a brief overview of the headline features of OPC-UA and a comparison with OPC-DA and outlines the necessity of migrating from OPC-DA and the motivaion for migraing to OPC-UA. Feedback from research into the avaiblability of tools and testing utilities will be presented and a practical overview of what will be required from a computing perspecive in order to run OPC-UA clients and servers in the CERN network.

Tree Branching: Leonardo da Vinci's Rule versus Biomechanical Models  

PubMed Central

This study examined Leonardo da Vinci's rule (i.e., the sum of the cross-sectional area of all tree branches above a branching point at any height is equal to the cross-sectional area of the trunk or the branch immediately below the branching point) using simulations based on two biomechanical models: the uniform stress and elastic similarity models. Model calculations of the daughter/mother ratio (i.e., the ratio of the total cross-sectional area of the daughter branches to the cross-sectional area of the mother branch at the branching point) showed that both biomechanical models agreed with da Vinci's rule when the branching angles of daughter branches and the weights of lateral daughter branches were small; however, the models deviated from da Vinci's rule as the weights and/or the branching angles of lateral daughter branches increased. The calculated values of the two models were largely similar but differed in some ways. Field measurements of Fagus crenata and Abies homolepis also fit this trend, wherein models deviated from da Vinci's rule with increasing relative weights of lateral daughter branches. However, this deviation was small for a branching pattern in nature, where empirical measurements were taken under realistic measurement conditions; thus, da Vinci's rule did not critically contradict the biomechanical models in the case of real branching patterns, though the model calculations described the contradiction between da Vinci's rule and the biomechanical models. The field data for Fagus crenata fit the uniform stress model best, indicating that stress uniformity is the key constraint of branch morphology in Fagus crenata rather than elastic similarity or da Vinci's rule. On the other hand, mechanical constraints are not necessarily significant in the morphology of Abies homolepis branches, depending on the number of daughter branches. Rather, these branches were often in agreement with da Vinci's rule. PMID:24714065

The ATLAS PanDA Monitoring System and its Evolution  

NASA Astrophysics Data System (ADS)

The PanDA (Production and Distributed Analysis) Workload Management System is used for ATLAS distributed production and analysis worldwide. The needs of ATLAS global computing imposed challenging requirements on the design of PanDA in areas such as scalability, robustness, automation, diagnostics, and usability for both production shifters and analysis users. Through a system-wide job database, the PanDA monitor provides a comprehensive and coherent view of the system and job execution, from high level summaries to detailed drill-down job diagnostics. It is (like the rest of PanDA) an Apache-based Python application backed by Oracle. The presentation layer is HTML code generated on the fly in the Python application which is also responsible for managing database queries. However, this approach is lacking in user interface flexibility, simplicity of communication with external systems, and ease of maintenance. A decision was therefore made to migrate the PanDA monitor server to Django Web Application Framework and apply JSON/AJAX technology in the browser front end. This allows us to greatly reduce the amount of application code, separate data preparation from presentation, leverage open source for tools such as authentication and authorization mechanisms, and provide a richer and more dynamic user experience. We describe our approach, design and initial experience with the migration process.

1991 DA: An asteroid in a bizarre orbit  

NASA Technical Reports Server (NTRS)

Asteroidal object 1991 DA has an orbit of high inclination, crossing the planets from Mars to Uranus. This is unique for an asteroid, but not unusual for a comet of the Halley-type: it therefore seems likely that 1991 DA is an extinct or dormant comet. Previous CCD imaging has shown no indication of a coma; spectroscopic observations of 1991 DA which lack any evidence of strong comet-like emissions are reported. Numerical integrations of the orbit of this object were performed which show that is has been remarkably stable for the past approximately 20,000 yr, but chaotic before that. This may allow a new estimate to be made of the physical lifetimes of comets.

Resolvendo a equao de Schrdinger atravs da substituio direta da srie de potncias  

E-print Network

This work presents a direct and highly accurate method to solve ordinary differential equations, in particular the Schr\\"odinger equation in one dimension, through the direct substitution of a power series solution to obtain a purely algebraical system containing the recurrence relations among the series coefficients. With these recurrence relations at hand it is possible to build an extremely simple routine using only basic arithmetic operations to find solutions of very high accuracy at a very low cost of machine resources. For the Schr\\"odinger equation the energy eigenvalues may be estimated by a very simple method, an this estimate may be easily refined using the recurrence relations until the specified tolerance has been reached, which allows one to find high accuracy wavefunctions even for states with very high quantum numbers. ----- Este trabalho apresenta um m\\'etodo direto e de alta acur\\'acia para resolver equa\\c{c}\\~oes diferenciais ordin\\'arias, em particular a equa\\c{c}\\~ao de Schr\\"odinger em uma dimens\\~ao, atrav\\'es da substitui\\c{c}\\~ao direta de uma solu\\c{c}\\~ao em s\\'erie de pot\\^encias para obter um sistema puramente alg\\'ebrico contendo as rela\\c{c}\\~oes de recorr\\^encia entre os coeficientes da s\\'erie.

Identification of a 13-kDa protein associated with the polyhydroxyalkanoic acid granules from Acinetobacter spp  

Microsoft Academic Search

Proteins associated with poly-?-hydroxybutyrate (PHB) granules were purified from four Acinetobacter strains isolated from modified activated sludge treatment plants. Four predominant proteins of 64 kDa, 41 kDa, 38 kDa and 13 kDa were identified. N-terminal amino acid sequencing of the 64-kDa and 13-kDa proteins from Acinetobacter RA3849 identified these proteins as the products of the phaCAc and phaPAc (formerly designated

The 16-kDa fragment of prolactin (16-kDa PRL), derived from proteolytic cleavage of 23-kDa PRL, was shown to have antiangiogenic activity. Previous studies have shown that recombinant 16-kDa PRL produced from bacteria often contained endotoxins, which are cytotoxic to endothelial cells, and varied in its biological activity due to changes in its refolding from inclusion bodies.

Roles and Delegation of Authority (R/DA) System  

SciTech Connect

The processes of defining managerial roles and providing for delegation of authority are essential to any enterprise. At most large organizations, these processes are defined in policy manuals and through sets of standard operating procedures for many, if not all, business and administrative functions. Many of these staff-initiated, administrative functions require the routing of documents for approval to one or more levels of management. These employee-oriented, back office types of workflows tend to require more flexibility in determining to whom these documents should go to, while, at the same time, providing the responsible parties with the flexibility to delegate their approval authority or allow others to review their work. Although this practice is commonplace in manual, paper-based processes that exist in many organizations, it is difficult to provide the same flexibility in the more structured, electronic-based, workflow systems. The purpose of this report is to present a framework or architecture for creating a R/DA system and provide some insights associated with its design and utilization. To improve understanding and clarify subsequent discussion, the goals and requirements for the major R/DA system components, namely, the database and interface modules, are initially presented along with the identification of important concepts and the definition of critical terms. Next high-level functions relating the types of inputs to the outputs of the R/DA interface module are introduced and discussed. Then the relationships between the major R/DA modules and the primary components associated with its creation and maintenance are presented and analyzed. Finally, some conclusions are drawn relative to the advantages associated with developing a R/DA system for use in implementing an enterprise-wide, work-facilitating information system.

DA-9801 Promotes Neurite Outgrowth via ERK1/2-CREB Pathway in PC12 Cells.  

PubMed

In the present study, we examined the mechanisms underlying the effect of DA-9801 on neurite outgrowth. We found that DA-9801 elicits its effects via the mitogen-activated protein kinase (MEK) extracellular signal-regulated kinase (ERK)1/2-cAMP response element-binding protein (CREB) pathway. DA-9801, an extract from a mixture of Dioscorea japonica and Dioscorea nipponica, was reported to promote neurite outgrowth in PC12 cells. The effects of DA-9801 on cell viability and expression of neuronal markers were evaluated in PC12 cells. To investigate DA-9801 action, specific inhibitors targeting the ERK signaling cascade were used. No cytotoxicity was observed in PC12 cells at DA-9801 concentrations of less than 30 ?g/mL. In the presence of nerve growth factor (NGF, 2 ng/mL), DA-9801 promoted neurite outgrowth and increased the relative mRNA levels of neurofilament-L (NF-L), a marker of neuronal differentiation. The Raf-1 inhibitor GW5074 and MEK inhibitor PD98059 significantly attenuated DA-9801-induced neurite outgrowth. Additionally, the MEK1 and MEK2 inhibitor SL327 significantly attenuated the increase in the percentage of neurite-bearing PC12 cells induced by DA-9801 treatment. Conversely, the selective p38 mitogen-activated protein kinase inhibitor SB203580 did not attenuate the DA-9801 treatment-induced increase in the percentage of neurite-bearing PC12 cells. DA-9801 enhanced the phosphorylation of ERK1/2 and CREB in PC12 cells incubated with and without NGF. Pretreatment with PD98059 blocked the DA-9801-induced phosphorylation of ERK1/2 and CREB. In conclusion, DA-9801 induces neurite outgrowth by affecting the ERK1/2-CREB signaling pathway. Insights into the mechanism underlying this effect of DA-9801 may suggest novel potential strategies for the treatment of peripheral neuropathy. PMID:25482167

TA-DA: A TOOL FOR ASTROPHYSICAL DATA ANALYSIS  

SciTech Connect

We present the Tool for Astrophysical Data Analysis (TA-DA), a new software aimed to greatly simplify and improve the analysis of stellar photometric data in comparison with theoretical models, and allow the derivation of stellar parameters from multi-band photometry. Its flexibility allows one to address a number of such problems: from the interpolation of stellar models, or sets of stellar physical parameters in general, to the computation of synthetic photometry in arbitrary filters or units; from the analysis of observed color-magnitude diagrams to a Bayesian derivation of stellar parameters (and extinction) based on multi-band data. TA-DA is available as a pre-compiled Interactive Data Language widget-based application; its graphical user interface makes it considerably user-friendly. In this paper, we describe the software and its functionalities.

Improving Security in the ATLAS PanDA System  

NASA Astrophysics Data System (ADS)

The security challenges faced by users of the grid are considerably different to those faced in previous environments. The adoption of pilot jobs systems by LHC experiments has mitigated many of the problems associated with the inhomogeneities found on the grid and has greatly improved job reliability; however, pilot jobs systems themselves must then address many security issues, including the execution of multiple users' code under a common 'grid' identity. In this paper we describe the improvements and evolution of the security model in the ATLAS PanDA (Production and Distributed Analysis) system. We describe the security in the PanDA server which is in place to ensure that only authorized members of the VO are allowed to submit work into the system and that jobs are properly audited and monitored. We discuss the security in place between the pilot code itself and the PanDA server, ensuring that only properly authenticated workload is delivered to the pilot for execution. When the code to be executed is from a 'normal' ATLAS user, as opposed to the production system or other privileged actor, then the pilot may use an EGEE developed identity switching tool called gLExec. This changes the grid proxy available to the job and also switches the UNIX user identity to protect the privileges of the pilot code proxy. We describe the problems in using this system and how they are overcome. Finally, we discuss security drills which have been run using PanDA and show how these improved our operational security procedures.

Stroemgren photometry of ZZ Ceti and other DA white dwarfs  

SciTech Connect

Stroemgren colors for a sample of 71 stars classified as DA white dwarfs are presented. Comparison with the recent model atmospheres of the Kiel group indicates that the average gravity of 63 stars of the sample is log g = 7.98 +- 0.31, with no indication of a dependence on the effective temperature. This is consistent with the theoretical expectation that white dwarfs evolve at constant gravity. Correlations between Stroemgren colors and Greenstein multichannel colors are also given, using 52 stars that have been observed in common in the two systems. These correlations are used to compare the data with a second set of model atmospheres computed by Shipman. Contrary to what has been suggested in the past, no fundamental differences are found when confronting the Stroemgren data with the DA model atmospheres of Shipman or those of the Kiel group. Finally, observations of 11 pulsating objects reveal the existence of a narrow instability strip in the range 13 000 K> or approx. =T/sub e/> or approx. =11 000 K in a ((u-b), (b-y)) two-color diagram. The present results add evidence to the contention that all DA white dwarfs evolve to become ZZ Ceti pulsators in the instability strip.

Two different molecular species of pig calpastatin. Structural and functional relationship between 107 kDa and 68 kDa molecules.  

PubMed Central

Calpastatin, the inhibitor protein acting specifically on calpain (EC 3.4.22.17; Ca2+-dependent cysteine proteinase), is known to be widely distributed in mammalian and avian cells. Two different molecular species of calpastatin were isolated and purified to homogeneity from pig heart muscle and from pig erythrocytes, and shown to be of 107 kDa and 68 kDa respectively on SDS/polyacrylamide-gel electrophoresis. Both calpastatins had very similar amino acid compositions when expressed as mol per cent of the residues, differed by only 0.1 pH unit in their isoelectric points, and showed immunological cross-reactivity. One molecule of the 107 kDa species could bind approx. 8 calpain molecules, whereas the 68 kDa inhibitor could bind approx. 5 calpain molecules. These findings suggest similar protein structures of the 107 kDa and 68 kDa calpastatins, each being composed of extended multidomains, with unit inhibitor domains aligned along the polypeptide chain of the molecule. The present study does not conclude, however, whether or not the 68 kDa calpastatin found in erythrocytes is a derived product from the 107 kDa species, which is present as such in heart muscle.

Larch arabinogalactan for hepatic drug delivery: isolation and characterization of a 9 kDa arabinogalactan fragment.  

PubMed

Purified arabinogalactan [AG(37 kDa)] from Larix occidentalis is composed of repeating units of similar molecular weight and composition. A 9 kDa arabinogalactan [AG(9 kDa)] has been obtained in high yield from AG(37 kDa) either by autoclaving at 121 degrees C or by exposure to alkaline solution in the presence of sodium borohydride. The weight average molecular weight of AG(37 (kDa) was determined to be 37 and 38 kDa by intensity light scattering and sedimentation equilibrium, respectively. The weight average molecular weight of AG(9 kDa) was determined to be 9.1 and 9.5 kDa by intensity light scattering and sedimentation equilibrium, respectively. MALDI-TOF mass spectrometry yielded a molecular weight at the peak of the distribution of 8.3 kDa for AG(9 kDa). Both AG(37 kDa) and AG(9 kDa) exhibited narrow molecular-weight distributions (Mw/Mn approximately 1.2). AG(37 kDa) and AG(9 kDa) exhibit nearly identical 13C-NMR spectra, monosaccharide composition, and sugar linkages. It is proposed that AG(37 kDa) is composed of covalently bound subunits of AG(9 kDa). AG(37 kDa) and AG(9 kDa) bind isolated hepatocyte asialoglycoprotein receptor equally well. As a result AG(9 kDa) is a candidate for use in hepatocyte directed drug delivery and may be more desirable for such use than is AG(37 kDa). PMID:8536264

A teoria da percolao aplicada s galxias aneladas peculiares  

NASA Astrophysics Data System (ADS)

Formulado no final da dcada de 50, o modelo de percolao concentra-se em descrever o meio poroso, que ser visto neste trabalho como uma rede de canais aleatrios, por onde escoa um fluido determinstico. Se o nmero de canais for suficientemente grande, ento eles estaro ligados e o meio se tornar permevel passagem do fluido. Neste caso, dizemos que houve a percolao do fluido. Reformulando o modelo acima, podemos escrever um cdigo particularmente adaptado para simulaes em Galxias, onde iremos supor que os canais formam um reticulado, e que cada stio da rede representa um poro que ser interpretado como uma regio ativa de formao estelar. Para cada elo teremos um pequeno canal ligando dois stios vizinhos, que poder, aps um tempo "t", induzir ou no a formao de uma regio ativa no poro vizinho. Para simular a passagem desta regio ativa atravs dos poros, diremos que um elo est aberto com probabilidade p e fechado com probabilidade 1-p. Dessa forma, passamos a imaginar configuraes de elos abertos e fechados, onde cada configurao ocorre com uma certa probabilidade, dada por p|A|(1-p)|F|, onde |A| o nmero de elos abertos e |F| o nmero de elos fechados da configurao. A expresso anterior s tem importncia fsica se |A| e |F| forem ambos finitos, pois, caso contrrio, a probabilidade de ocorrncia de uma dada configurao ser sempre nula. Neste trabalho, foram considerados dados cinemticos publicados na literatura bem como aqueles obtidos pelos autores a partir de observaes fotomtricas realizadas no Observatrio de Las Campans, em 1994, para a Galxia Anelada Peculiar HRG 03401.

18 kDa translocator protein - implications in cell's functions.  

PubMed

The mitochondrial 18kDa Translocation Protein (TSPO) was first identified in 1977 by its capability to bind benzodiazepines in peripheral tissues. It is more commonly known after its previous name - peripheral benzodiazepine receptor (PBR) as opposed to the central benzodiazepine receptor (CBR), from which it differs by location, structure and function. It is ubiquitous with highest expression in steroid-producing tissues, like adrenal cortex, ovaries, testicles, and placenta. The role of TSPO is crucial for living; its inactivation results in early embryonic-lethal phenotype in mice. TSPO has been implicated in various functions of cell, including steroidogenesis, cellular respiration, reactive oxygen species production, heme biosynthesis, immunomodulation, apoptosis, and cellular proliferation. TSPO has been shown to interact with other cellular proteins: 32 kDa voltage-dependent anion channel (VDAC), 30 kDa adenine nucleotide translocase (ANT), cyclophilin D, hexokinase, creatinine kinase, diazepam binding inhibitor (DBI), phosphate carrier and Bcl-2 family. They are - involved in the formation and regulation of mitochondrial permeability transition pore (mPTP) at the junction of the inner and outer mitochondrial membranes. While the function and characteristics of the mPTP are known, its well defined, but its structure remains speculative. Changes in TSPO expression are associated with multiple disorders, including cancer, ischaemia-reperfusion injury, neurological diseases and psychiatric disorders, atheromatosis, and others. - TSPO is able to bind cholesterol, porphyrins and other ligands with different affinity. The current knowledge of TSPO implicates its potential use as a diagnostic marker and therapeutic target in different diseases and their therapies. PMID:25589712

Negligible pharmacokinetic interaction between oral DA-8159, a new erectogenic, and amlodipine in rats.  

PubMed

A pharmacokinetic interaction between oral DA-8159 and amlodipine was evaluated in male Sprague-Dawley rats. In rats pretreated with troleandomycin (a main inhibitor of CYP3A1/2 in rats), the AUC(0-6 h) of amlodipine was significantly greater than the controls (34.5+/-6.01 compared with 28.0+/-4.70 microg min/ml), indicating that amlodipine is metabolized via CYP3A1/2 in rats. It was reported that the metabolism of DA-8159 and the formation of DA-8164 (a metabolite of DA-8159) were mainly mediated via CYP3A1/2 in rats, and amlodipine significantly inhibited the CYP3A2 in rats. Therefore, a pharmacokinetic interaction between the two drugs could be expected. However, after oral administration of DA-8159 at a dose of 30 mg/kg with or without oral amlodipine at a dose of 5 mg/kg to rats, the pharmacokinetic parameters of DA-8159 and DA-8164 were not significantly different between the two groups of rats. Similar results were also obtained from amlodipine between with and without DA-8159. The above data indicated that the pharmacokinetic interaction between oral DA-8159 and amlodipine was almost negligible in rats. PMID:16400709

The effect of repeated amphetamine treatment on striatal DA transporter and rotation in rats.  

PubMed

The effect of repeated amphetamine treatment on the involvement of the striatal DA transporters in rotation behavior was tested in rats. Repeated amphetamine treatment had no effect on [3H]DA uptake or [3H]GBR-12935 binding density. However, unlike the naive rats who rotated away from the striatum with a lower density of DA transporters, rats sensitized to amphetamine rotated toward the striatum with a lower density of DA transporters. These findings imply that repeated amphetamine augments the subcortical involvement in behavioral output. PMID:7704609

Evolution of the ATLAS PanDA workload management system for exascale computational science  

NASA Astrophysics Data System (ADS)

An important foundation underlying the impressive success of data processing and analysis in the ATLAS experiment [1] at the LHC [2] is the Production and Distributed Analysis (PanDA) workload management system [3]. PanDA was designed specifically for ATLAS and proved to be highly successful in meeting all the distributed computing needs of the experiment. However, the core design of PanDA is not experiment specific. The PanDA workload management system is capable of meeting the needs of other data intensive scientific applications. Alpha-Magnetic Spectrometer [4], an astro-particle experiment on the International Space Station, and the Compact Muon Solenoid [5], an LHC experiment, have successfully evaluated PanDA and are pursuing its adoption. In this paper, a description of the new program of work to develop a generic version of PanDA will be given, as well as the progress in extending PanDA's capabilities to support supercomputers and clouds and to leverage intelligent networking. PanDA has demonstrated at a very large scale the value of automated dynamic brokering of diverse workloads across distributed computing resources. The next generation of PanDA will allow other data-intensive sciences and a wider exascale community employing a variety of computing platforms to benefit from ATLAS' experience and proven tools.

Da Vinci's codex and the anatomy of healthcare.  

PubMed

We usually display a laid-back approach to medical jargon throughout our theatre work. The word 'perioperative' is built from the Greek word 'peri' (around) and the Latin 'operari' (to work). Latin and Greek became the prefixed language of choice for Leonardo da Vinci, and his research was pivotal in determining the way in which surgical procedures are documented. Ancient manuscripts aided the unfolding of the secrets of anatomy, and Leonardo revealed that art was the key in expressive detailed explanation. PMID:23248927

Visual tracking of da Vinci instruments for laparoscopic surgery  

NASA Astrophysics Data System (ADS)

Intraoperative tracking of laparoscopic instruments is a prerequisite to realize further assistance functions. Since endoscopic images are always available, this sensor input can be used to localize the instruments without special devices or robot kinematics. In this paper, we present an image-based markerless 3D tracking of different da Vinci instruments in near real-time without an explicit model. The method is based on different visual cues to segment the instrument tip, calculates a tip point and uses a multiple object particle filter for tracking. The accuracy and robustness is evaluated with in vivo data.

A PEG-DA microfluidic device for chemotaxis studies  

NASA Astrophysics Data System (ADS)

The study of cells in a well-defined and chemically programmable microenvironment is essential for a complete and fundamental understanding of the cell behaviors with respect to specific chemical compounds. Flow-free microfluidic devices that generate quasi-steady chemical gradients (spatially varying but temporally constant) have been demonstrated as effective chemotaxis assay platforms due to dissociating the effect of chemical cues from mechanical shear forces caused by fluid flow. In this work, we demonstrate the fabrication and characterization of a flow-free microfluidic platform made of polyethylene glycol diacrylate (PEG-DA) hydrogel. We have demonstrated that the mass transport properties of these devices can be customized by fabricating them from PEG-DA gels of four distinct molecular weights. In contrast to microfluidic devices developed using soft lithography; this class of devices can be realized using a more cost-effective approach of direct photopolymerization with fewer microfabrication steps. This microfluidic platform was tested by conducting a quantitative study of the chemotactic behavior of Escherichia coli (E. coli) RP437, a model microorganism, in presence of the chemo-effector, casamino-acids. Using the microfabrication and characterization methodology presented in this work, microfluidic platforms with well-defined and customizable diffusive properties can be developed to accommodate the study of a wide range of cell types.

Chandra Confirmation of a Pulsar Wind Nebula in DA 495  

NASA Technical Reports Server (NTRS)

As part of a multiwavelength study of the unusual radio supernova remnant DA 495, we present observations made with the Chandra X-ray Observatory. Imaging and spectroscopic analysis confirms the previously detected X-ray source at the heart of the annular radio nebula, establishing the radiative properties of two key emission components: a soft unresolved source with a blackbody temperature of 1 MK consistent with a neutron star, surrounded by a nontherma1 nebula 40" in diameter exhibiting a power-law spectrum with photon index Gamma = 1.63, typical of a pulsar wind nebula. Morphologically, the nebula appears to be slightly extended along a direction, in projection on the sky, previously demonstrated to be of significance in radio and ASCA observations; we argue that this represents the orientation of the pulsar spin axis. At smaller scales, a narrow X-ray feature is seen extending out 5" from the point source, but energetic arguments suggest that it is not the resolved termination shock of the pulsar wind against the ambient medium. Finally, we argue based on synchrotron lifetimes in the nebular magnetic field that DA 495 represents the first example of a pulsar wind nebula in which electromagnetic flux makes up a significant part, together with particle flux, of the neutron star's wind.

SBS TDMA-DA system with VAC and DAC  

NASA Astrophysics Data System (ADS)

This paper describes many of the design considerations involved in developing the demand assignment (DA) subsystem of the TDMA satellite communication system for Satellite Business Systems. Each earth station has a satellite communications controller (SCC) which requests capacity to meet current voice and data traffic demands. A central reference station frequently reallocates capacity based on the requests of all the earth stations in a network. To minimize the amount of satellite capacity required, the SCC has a circuit-switching capability for voice calls as well as for digital data calls. Furthermore, the SCC employs voice activity compression (VAC) and data activity compression (DAC), in which the amount of capacity requested is based on measured average speech activity as well as the number of off-hook voice ports and the number of off-hook data ports. Data calls are queued on a first-come, first-served basis when capacity is not immediately available. The reference station distributes excess capacity according to a nonlinear table lookup procedure so that the voice call blocking probability is equalized across the network. The DA system makes much more efficient use of satellite transmission capacity than a design with fixed-capacity trunk routes.

In order to evaluate the Mycobacterium avium subsp. paratuberculosis (M. avium subsp. paratuberculosis) 19-kDa lipoprotein as an immunomodulator in cattle with Johne's disease, the gene encoding the 19-kDa protein (MAP0261c) was analyzed. Results MAP0261c is conserved in mycobacteria, showing a 95% amino acid identity in M. avium subspecies avium, 84% in M. intracellulare and 76% in M. bovis and M. tuberculosis. MAP0261c was cloned, expressed, and purified as a fusion protein with the maltose-binding protein (MBP-19 kDa) in Escherichia coli. IFN-? production was measured from 21 naturally infected and 9 control cattle after peripheral blood mononuclear cells (PBMCs) were stimulated with a whole cell lysate (WCL) of M. avium subsp. paratuberculosis or the recombinant MBP-19 kDa. Overall, the mean response to MBP-19 kDa was not as strong as the mean response to the WCL. By comparison, cells from control, non-infected cattle did not produce IFN-? after stimulation with either WCL or MBP-19 kDa. To assess the humoral immune response to the 19-kDa protein, sera from cattle with clinical Johne's disease were used in immunoblot analysis. Reactivity to MBP-19 kDa protein, but not MBP alone, was observed in 9 of 14 infected cattle. Antibodies to the 19-kDa protein were not observed in 8 of 9 control cows. Conclusions Collectively, these results demonstrate that while the 19-kDa protein from M. avium subsp. paratuberculosis stimulates a humoral immune response and weak IFN-? production in infected cattle, the elicited responses are not strong enough to be used in a sensitive diagnostic assay.

Bovine Prion Is Endocytosed by Human Enterocytes via the 37 kDa/67 kDa Laminin Receptor  

PubMed Central

Some forms of transmissible spongiform encephalopathies result from oral infection. We have thus analyzed the early mechanisms that could account for an uptake of infectious prion particles by enterocytes, the major cell population of the intestinal epithelium. Human Caco-2/TC7 enterocytes cultured on microporous filters were incubated with different prion strains and contaminated brain homogenates in the apical compartment. Internalization of infectious particles was analyzed by Western blotting and immunofluorescence. We observed internalization by enterocytes of prion particles from bovine spongiform encephalopathy brain homogenates but not from mouse-adapted scrapie-strain brain homogenates or purified bovine spongiform encephalopathy scrapie-associated fibrils. Bovine prion particles were internalized via endocytosis within minutes of infection and were associated with subapical vesicular structures related to early endosomes. The endocytosis of the infectious bovine PrPSc was reduced by preincubating the cells with an anti-LRP/LR blocking antibody, identifying the 37 kDa/67 kDa laminin receptor (LRP/LR), which is apically expressed in Caco-2/TC7 cells, as the receptor for the infectious prion protein. Altogether, our results underscore a potential role of enterocytes in the absorption of bovine prions during oral infection through specific LRP/LR-dependent endocytosis. PMID:16192638

The 37kDa/67kDa Laminin Receptor acts as a receptor for A?42 internalization  

PubMed Central

Neuronal loss is a major neuropathological hallmark of Alzheimer's disease (AD). The associations between soluble A? oligomers and cellular components cause this neurotoxicity. The 37?kDa/67?kDa laminin receptor (LRP/LR) has recently been implicated in A? pathogenesis. In this study the mechanism underlying the pathological role of LRP/LR was elucidated. Frsters Resonance Energy Transfer (FRET) revealed that LRP/LR and A? form a biologically relevant interaction. The ability of LRP/LR to form stable associations with endogenously shed A? was confirmed by pull down assays and A?-ELISAs. Antibody blockade of this association significantly lowered A?42 induced apoptosis. Furthermore, antibody blockade and shRNA mediated downregulation of LRP/LR significantly hampered A?42 internalization. These results suggest that LRP/LR is a receptor for A?42 internalization, mediating its endocytosis and contributing to the cytotoxicity of the neuropeptide by facilitating intra-cellular A?42 accumulation. These findings recommend anti-LRP/LR specific antibodies and shRNAs as potential therapeutic tools for AD treatment. PMID:24990253

The history of veterinary medicine is closely tied to the development of human medicine. Evidence of animal medicine has been found in ancient civilizations, such as those of the Hindu, Babylonians, Hebrews, Arabs, Greeks, and Romans. Ancient Indian literature in the form of the holy V?da, Pur?na, Br?hma?a, epics, etc. is flooded with information on animal care. The Pur??a are ancient scriptures discuss varied topics like devotion to God and his various aspects, traditional sciences like Ayurv?da, Jy?ti?a (Astrology), cosmology, concepts like dharma, karma, reincarnation and many others. The treatment of animal diseases using Ayurvedic medicine has been mentioned in Garudapur?na, Agnipur??a, Atri-samhit?, Matsyapur??a and many other texts. The Garudapur??a is one of the important S?ttvika pur?na, the subject matter is divided into two parts, viz. P?rvakha?da (first part) and an Uttarakha?da (subsequent part).

Intramembrane translocation and posttranslational palmitoylation of the chloroplast 32-kDa herbicide-binding protein  

SciTech Connect

The 32-kDa herbicide-binding protein, a component of photosystem II, is synthesized as a membrane-associated 33.5-kDa precursor within the chloroplast. We show that membrane attachment of the precursor and processing to the 32-kDa form occur in the unstacked stromal lamellae. Once processed, the 32-kDa protein translocates, within the thylakoids, to the topologically distinct stacked granal lamellae. Posttranslational palmitoylation of the processed 32-kDa protein is also shown to occur. This modification takes place in a membrane-protected domain and is mainly confined to the protein assembled in the granal lamellae, where functional photosystem II centers are concentrated.

Evidence for a 12?kDa Carrier Protein for Natriuretic Hormone  

PubMed Central

The search for the elusive Na-K-ATPase-inhibiting natriuretic hormone continues. In this review, evidence is presented that isolating the carrier protein for natriuretic hormone from hypertensive plasma is a necessary first step before splitting off the final hormone. The carrier protein has a molecular weight of 12?kDa while the final hormone has a molecular weight of 408?Da. Both compounds inhibit Na-K-ATPase but the compound containing the carrier protein predominates. The question has been raised as to whether the carrier protein is in actuality proANF, a 17?kDa protein that can be split between a 14?kDa protein (the presumptive proANF) and the 3?kDa ANF.

70 DA WHITE DWARFS IDENTIFIED IN LAMOST PILOT SURVEY  

SciTech Connect

We present a spectroscopically identified catalog of 70 DA white dwarfs (WDs) from the LAMOST pilot survey. Thirty-five are found to be new identifications after cross-correlation with the Eisenstein et al. and Villanova catalogs. The effective temperature and gravity of these WDs are estimated by Balmer lines fitting. Most of them are hot WDs. The cooling times and masses of these WDs are estimated by interpolation in theoretical evolution tracks. The peak of the mass distribution is found to be {approx}0.6 M {sub Sun }, which is consistent with prior work in the literature. The distances of these WDs are estimated using the method of synthetic spectral distances. All of these WDs are found to be in the Galactic disk from our analysis of space motions. Our sample supports the expectation that WDs with high mass are concentrated near the plane of the Galactic disk.

DA White Dwarfs Observed in the LAMOST Pilot Survey  

NASA Astrophysics Data System (ADS)

A total of ~640, 000 objects from the LAMOST pilot survey have been publicly released. In this work, we present a catalog of DA white dwarfs (DAWDs) from the entire pilot survey. We outline a new algorithm for the selection of white dwarfs (WDs) by fitting Srsic profiles to the Balmer H?, H?, and H? lines of the spectra, and calculating the equivalent width of the Ca II K line. Two thousand nine hundred sixty-four candidates are selected by constraining the fitting parameters and the equivalent width of the Ca II K line. All the spectra of candidates are visually inspected. We identify 230 DAWDs (59 of which are already included in the Villanova and SDSS WD catalogs), 20 of which are DAWDs with non-degenerate companions. In addition, 128 candidates are classified as DAWDs/subdwarfs, which means the classifications are ambiguous. The result is consistent with the expected DAWD number estimated based on the LEGUE target selection algorithm.

Leonardo da Vinci: the search for the soul.  

PubMed

The human race has always contemplated the question of the anatomical location of the soul. During the Renaissance the controversy crystallized into those individuals who supported the heart ("cardiocentric soul") and others who supported the brain ("cephalocentric soul") as the abode for this elusive entity. Leonardo da Vinci (1452-1519) joined a long list of other explorers in the "search for the soul." The method he used to resolve this anatomical problem involved the accumulation of information from ancient and contemporary sources, careful notetaking, discussions with acknowledged experts, and his own personal search for the truth. Leonardo used a myriad of innovative methods acquired from his knowledge of painting, sculpture, and architecture to define more clearly the site of the "senso comune"--the soul. In this review the author examines the sources of this ancient question, the knowledge base tapped by Leonardo for his personal search for the soul, and the views of key individuals who followed him.

43 kDa and 66 kDa, two blood stage antigens induce immune response in Plasmodium berghei malaria.  

PubMed

The hunt for an effective vaccine against malaria still continues. Several new target antigens as candidates for vaccine design are being explored and tested for their efficacy. In the present study the sera from mice immunized with 24,000 x g fraction of Plasmodium berghei has been used to identify highly immunogenic blood stage antigens. The protective antibodies present in immune sera were covalently immobilized on CNBr activated sepharose 4B and used for affinity chromatography purification of antigens present in blood stages of P. berghei. Two polypeptides of 66 and 43 kDa molecular weights proved to be highly immunogenic. They exhibited a strong humoral immune response in mice as evident by high titres in ELISA and IFA. Protective immunity by these two antigens was apparent by in vivo and in vitro studies. These two proteins could further be analysed and used as antigens in malaria vaccine design. PMID:25141540

The immune response to 52-kDa Ro and 60-kDa Ro is linked in experimental autoimmunity.  

PubMed

Clustering of autoantibody specificities is a consistent finding in patients with systemic autoimmune diseases. Patients with Sjgren's syndrome frequently have autoantibodies to La, 60-kDa Ro(SS-A) protein (Ro60), and 52-kDa Ro(SS-A) protein (Ro52). In the case of anti-Ro60 and anti-La, there is evidence that these specificities occur together because of the physical association of the Ro60 and La proteins that form a ribonucleoprotein particle (RNP). Thus, the autoantibody response may spread from a single epitope to involve new epitopes located within other components of the RNP. The physical association of Ro52 with the Ro/La RNP has remained controversial, implying that Abs to Ro52 are not a consequence of intermolecular spreading and may be triggered independently of the anti-Ro60 response. To examine this relationship of the immune response to Ro52 and Ro60, mice were immunized with recombinant Ro52, Ro60, or La, and examined for autoantibody production. Immunization with Ro52 resulted in rapid, high titer Ab production to Ro52, followed 7 to 14 days later by lower titer autoantibody production to Ro60. Immunization with Ro60 led to anti-Ro60, which was also followed 7 to 14 days later by a lower titer anti-Ro52 response. Cross-reactivity of affinity-purified Abs from immune mouse sera was not observed. These observations suggest that the autoimmune responses to Ro60 and Ro52 are linked intrinsically, despite previous evidence suggesting they are not associated in vivo. The mechanism of linkage remains unclear, but the data are most consistent with some physical association of Ro52 and Ro60 allowing autoimmunization, presumably as a result of normal cell turnover or specific injury in vivo.

Endogenous dopamine (DA) modulates (3H)spiperone binding in vivo in rat brain  

SciTech Connect

(3H)spiperone (SPI) binding in vivo, biochemical parameters and behavior were measured after modulating DA levels by various drug treatments. DA releasers and uptake inhibitors increased SPI binding in rat striatum. In other brain areas, the effects were variable, but only the pituitary remained unaffected. Surprisingly, nomifensine decreased SPI binding in frontal cortex. The effects of these drugs were monitored by measuring DA, serotonin (5-HT) and their metabolites in the same rats. The increased SPI binding in striatum was parallel to the locomotor stimulation with the following rank order: amfonelic acid greater than nomifensine greater than D-amphetamine greater than or equal to methylphenidate greater than amineptine greater than bupropion. Decreasing DA levels with reserpine or alpha-methyl-para-tyrosine reduced SPI binding by 45% in striatum only when both drugs were combined. In contrast, reserpine enhanced SPI binding in pituitary. Thus, the amount of releasable DA seems to modulate SPI binding characteristics. It is suggested that in vivo, DA receptors are submitted to dynamic regulation in response to changes in intrasynaptic concentrations of DA.

Vectra DA for the objective measurement of disease activity in patients with rheumatoid arthritis.  

PubMed

Quantitative and regular assessment of disease activity in rheumatoid arthritis (RA) is required to achieve treatment targets such as remission and to optimize clinical outcomes. To assess inflammation accurately, predict joint damage and monitor treatment response, a measure of disease activity in RA should reflect the pathological processes resulting in irreversible joint damage and functional disability. The Vectra DA blood test is an objective measure of disease activity for patients with RA. Vectra DA provides an accurate, reproducible score on a scale of 1 to 100 based on the concentrations of 12 biomarkers that reflect the pathophysiologic diversity of RA. The analytical validity, clinical validity, and clinical utility of Vectra DA have been evaluated for patients with RA in registries and prospective and retrospective clinical studies. As a biomarker-based instrument for assessing disease activity in RA, the Vectra DA test can help monitor therapeutic response to methotrexate and biologic agents and assess clinically challenging situations, such as when clinical measures are confounded by non-inflammatory pain from fibromyalgia. Vectra DA scores correlate with imaging of joint inflammation and are predictive for radiographic progression, with high Vectra DA scores being associated with more frequent and severe progression and low scores being predictive for non-progression. In summary, the Vectra DA score is an objective measure of RA disease activity that quantifies inflammatory status. By predicting risk for joint damage more effectively than conventional clinical and laboratory measures, it has the potential to complement these measures and optimise clinical decision making.

Therapeutic effect of infused Fluosol-DA/carbogen with ephedrine, flunarizine, or nitroprusside  

SciTech Connect

The perfluorochemical emulsion Fluosol-DA plus carbogen breathing has been shown to increase the effectiveness of radiation therapy in preclinical solid tumors when the emulsion was administered by i.v. bolus injection. Much of the enhancement in tumor radiation response was lost when the emulsion was administered slowly. The authors hypothesized that an increase in tumor perfusion resulted when Fluosol-DA was administered rapidly. In the present study, the [alpha]/[beta] agonist ephedrine, the Ca[sup 2+] channel blocker flunarizine and the nitric oxide producing vasodilating drug nitroprusside have been tested. Ephedrine administration resulted in a decrease in the radiation plus Fluosol-DA [+-] carbogen antitumor effects in both the Lewis lung carcinoma and FSaIIC tumor systems. In contrast, flunarizine administration resulted in an increase in the efficacy of the radiation plus carbogen and the radiation plus Fluosol-DA/carbogen in both emulsion was given rapidly. Even with flunarizine administration Fluosol-DA delivered slowly was less effective than when the emulsion was given rapidly. Flunarizine with Fluosol-DA infused i.v. over 30 min followed by carbogen breathing prior to and during radiation therapy resulted in a 1.7-1.6-fold increase in response compared with 2.4-2.2-fold with Fluosol-DA administered by injection i.v. and carbogen breathing prior to and during radiation therapy using growth delay of the Lewis lung carcinoma. The effects of nitroprusside were complex. This drug had considerably more effect at 10 Gy than at higher radiation doses. These studies suggest that Fluosol-DA given by i.v. injection may increase tumor perfusion and that a drug like flunarizine may be beneficial if the Fluosol-DA is administered slowly followed by carbogen breathing and radiation therapy. 45 refs., 4 figs.

Porphyromonas gulae 41-kDa fimbriae induced osteoclast differentiation and cytokine production.  

PubMed

Porphyromonas gulae is considered to be associated with canine periodontitis. We have previously reported that the P. gulae American Type Culture Collection (ATCC) 51700 comprised 41-kDa fimbriae. The purpose of the present study was to demonstrate the roles of 41-kDa fimbrial protein in periodontal disease. In this study, we examined the involvement of the 41-kDa fimbrial protein in osteoclast differentiation and cytokine production in murine macrophages. Furthermore, alveolar bone resorption induced by P. gulae infection in rats was evaluated. To estimate osteoclast differentiation, bone marrow cells and MC3T3-G2/PA6 cells were cultured with or without the 41-kDa fimbrial protein for 7 days. BALB/c mouse peritoneal macrophages were stimulated with the 41-kDa fimbrial protein, and the levels of interleukin (IL)-1? and tumor necrosis factor (TNF)-? production were determined by enzyme-linked immunosorbent assay. Osteoclast differentiation was significantly enhanced by treatment with the 41-kDa fimbrial protein in a dose-dependent manner. The total area of pits formed on the dentine slices with osteoclasts incubated with the 41-kDa fimbrial protein was significantly greater than that of the control. The purified 41-kDa fimbrial protein induced IL-1? and TNF-? production in BALB/c mouse peritoneal macrophages after 6 hr of incubation in a dose-dependent manner. The bone loss level in rats infected with P. gulae was significantly higher than that of the sham-infected rats. These results suggest that P. gulae 41-kDa fimbriae play important roles in the pathogenesis of periodontal disease. PMID:25421499

Leonardo Da Vinci and stroke - vegetarian diet as a possible cause.  

PubMed

Leonardo da Vinci (April 15, 1452 to May 2, 1519) was an Italian Renaissance architect, musician, anatomist, inventor, engineer, sculptor, geometer, and painter. It has been gleaned from the many available historical documents that da Vinci was a vegetarian who respected and loved animals, and that he suffered from right hemiparesis in the last 5 years of his life. A vegetarian diet has both positive and negative influences on the cerebrovascular system. In this report, a possible relation between a vegetarian diet and stroke is discussed from various perspectives as related to Leonardo da Vinci's stroke. PMID:20375518

69-kDa and 100-kDa isoforms of interferon-induced (2'-5')oligoadenylate synthetase exhibit differential catalytic parameters.  

PubMed

The (2'-5')oligoadenylate synthetase represents a family of interferon-induced proteins which when activated by double-stranded (ds)RNA polymerizes ATP into 2'-5'-linked oligomers with the general formula pppA(2'p5'A)n, where n > 1, which for convenience are referred to as 2-5A. We studied here the influence of pH, dsRNA concentration and time on oligomeric composition of 2-5A synthesized by purified 69-kDa and 100-kDa isoforms of (2'-5')oligo(adenylate) synthetase. In optimal conditions for activity, the 69-kDa form synthesized higher oligomers of 2-5A molecules whereas the 100 kDa form synthesized preferentially dimeric molecules, which are known not to be functional for the activation of RNase L. This difference does not reflect a differential affinity of the enzymes for the preformed 2-5A dimer, which is found to be a very poor substrate for both enzymes. This latter strongly suggests that the mechanism of elongation is more likely processive. Moreover, we show that both isoforms have efficient nucleotidyl-transferase activity and provide evidence that, in optimized conditions, GTP can be used alone as substrate by these enzymes to generate pppG2'p5'G. Our results clearly demonstrate that the 69-kDa and 100-kDa forms of (2'-5')oligoadenylate synthetase manifest various differential catalytic activities, and favor the hypothesis that these enzymes might have other functions in the cell besides those in the 2-5A system.

DA WHITE DWARFS OBSERVED IN THE LAMOST PILOT SURVEY  

SciTech Connect

A total of {approx}640, 000 objects from the LAMOST pilot survey have been publicly released. In this work, we present a catalog of DA white dwarfs (DAWDs) from the entire pilot survey. We outline a new algorithm for the selection of white dwarfs (WDs) by fitting Sersic profiles to the Balmer H{beta}, H{gamma}, and H{delta} lines of the spectra, and calculating the equivalent width of the Ca II K line. Two thousand nine hundred sixty-four candidates are selected by constraining the fitting parameters and the equivalent width of the Ca II K line. All the spectra of candidates are visually inspected. We identify 230 DAWDs (59 of which are already included in the Villanova and SDSS WD catalogs), 20 of which are DAWDs with non-degenerate companions. In addition, 128 candidates are classified as DAWDs/subdwarfs, which means the classifications are ambiguous. The result is consistent with the expected DAWD number estimated based on the LEGUE target selection algorithm.

Da\\phi ne gamma-rays factory  

E-print Network

Gamma sources with high flux and spectral densities are the main requirements for new nuclear physics experiments to be performed in several worldwide laboratories and envisaged in the ELI-NP (Extreme Light Infrastructure-Nuclear Physics) project or in the IRIDE (Interdisciplinary Research Infrastructure with Dual Electron Linacs) proposals. The paper is focalized on an experiment of gamma photons production using Compton collisions between the DA\\Phi NE electron beam and a high average power laser pulse, amplified in a Fabry-P\\'erot optical resonator. The calculations show that the resulting gamma beam source has extremely interesting properties in terms of spectral density, energy spread and gamma flux comparable (and even better) with the last generation gamma sources. The energy of the gamma beam depends on the adopted laser wavelength and can be tuned changing the energy of the electron ring. In particular we have analyzed the case of a gamma factory tunable in the 2-9 MeV range. The main parameters of t...

DA?NE operation with electron-cloud-clearing electrodes.  

PubMed

The effects of an electron cloud (e-cloud) on beam dynamics are one of the major factors limiting performances of high intensity positron, proton, and ion storage rings. In the electron-positron collider DA?NE, namely, a horizontal beam instability due to the electron-cloud effect has been identified as one of the main limitations on the maximum stored positron beam current and as a source of beam quality deterioration. During the last machine shutdown in order to mitigate such instability, special electrodes have been inserted in all dipole and wiggler magnets of the positron ring. It has been the first installation all over the world of this type since long metallic electrodes have been installed in all arcs of the collider positron ring and are currently used during the machine operation in collision. This has allowed a number of unprecedented measurements (e-cloud instabilities growth rate, transverse beam size variation, tune shifts along the bunch train) where the e-cloud contribution is clearly evidenced by turning the electrodes on and off. In this Letter we briefly describe a novel design of the electrodes, while the main focus is on experimental measurements. Here we report all results that clearly indicate the effectiveness of the electrodes for e-cloud suppression. PMID:25166811

Temperature and Gravity Dependence of Trace Element Abundances in Hot DA White Dwarfs (94-EUVE-094)  

NASA Technical Reports Server (NTRS)

EUV spectroscopy has shown that DA white dwarfs hotter than about 45,000 K may contain trace heavy elements, while those hotter than about 50,000 K almost always have significant abundances of trace heavy elements. One of our continuing challenges is to identify and determine the abundances of these trace constituents, and then to relate the observed abundance patterns to the present conditions and previous evolutionary histories of the hot DA white dwarfs.

In vitro degradation of the 32kDa PS II reaction centre protein  

SciTech Connect

The 32kDa thylakoid membrane protein is an integral component of the PS II reaction centre. The protein, although stable in the dark, undergoes light dependent turnover. Light from the UV, visible and far-red spectral regions induce 32kDa protein degradation. To better understand 32kDa protein metabolism, an in vitro degradation system is being developed. It consists of isolated thylakoid membranes than contain radiolabelled protein. The 32kDa protein is actively and specifically degraded when the thylakoid preparation is exposed to UV or visible radiation. The protein is stable in the dark. The herbicides (atrazine and DCMU) inhibit degradation in the in vitro system as they do in vivo. Additionally, several methods of isolating thylakoids are being compared to optimize the 32kDa protein degradation reaction. The preparations will be evaluated based on their ability to permit light dependent degradation of the 32kDa protein without affecting the other membrane components.

Cutaneous leishmaniasis (CL) in the state of Rio de Janeiro is sporadic and can be characterised as a peridomestic transmission that occurs in modified natural environments. The aim of this work was to study the fauna and ecological characteristics of sandflies in an environmentally protected area (the State Park of Serra da Tiririca) within the remnants of the Atlantic Forest in the municipalities of Niteri and Maric and their possible relationship with leishmaniasis. Captures were performed using light traps during the night once a month for one year in both sylvatic environments and areas surrounding homes near the park. A total of 1,037 sandflies were captured, belonging to nine genera and 12 species: Evandromyia tupynambai (34.1%), Migonemyia migonei (20.6%), Brumptomyia cunhai (13.8%), Micropygomyia schreiberi (9.7%), Psathyromyia lanei (6.5%), Brumptomyia nitzulescui (5.7%), Evandromyia edwardsi (5.4%), Nyssomyia intermedia (2.8%), Evandromyia cortelezzii (0.6%), Pintomyia bianchigalatiae (0.5%), Lutzomyia longipalpis (0.2%) and Sciopemyia microps (0.1%). Both Mg. migonei and Ny. intermedia may be acting as vectors of CL in this area. PMID:24141956

Vinpocetine and ?-tocopherol prevent the increase in DA and oxidative stress induced by 3-NPA in striatum isolated nerve endings.  

PubMed

Vinpocetine is a neuroprotective drug that exerts beneficial effects on neurological symptoms and cerebrovascular disease. 3-nitropropionic acid (3-NPA) is a toxin that irreversibly inhibits succinate dehydrogenase, the mitochondrial enzyme that acts in the electron transport chain at complex II. In previous studies in striatum-isolated nerve endings (synaptosomes), we found that vinpocetine decreased dopamine (DA) at expense of its main metabolite 3,4-dihydroxyphenylacetic acid (DOPAC), and that 3-NPA increased DA, reactive oxygen species (ROS), DA-quinone products formation, and decreased DOPAC. Therefore, in this study, the possible effect of vinpocetine on 3-NPA-induced increase in DA, ROS, lipid peroxidation, and DA-quinone products formation in striatum synaptosomes were investigated, and compared with the effects of the antioxidant ?-tocopherol. Results show that the increase in DA induced by 3-NPA was inhibited by both 25?M vinpocetine and 50?M ?-tocopherol. Vinpocetine, as ?-tocopherol, also inhibited 3-NPA-induced increase in ROS (as judged by DCF fluorescence), lipid peroxidation (as judged by TBA-RS formation), and DA-quinone products formation (as judged by the nitroblue tetrazolium reduction method). As in addition to the inhibition of complex II exerted by 3-NPA, 3-NPA increases DA-oxidation products that in turn can inhibit other sites of the respiratory chain, the drop in DA produced by vinpocetine and ?-tocopherol may importantly contribute to their protective action from oxidative damage, particularly in DA-rich structures.

D-amphetamine (A)-induced dopamine (DA) release is not strictly dependent on newly-synthesized transmitter  

SciTech Connect

A is thought to exert its stimulant effects by releasing DA from a newly synthesized transmitter pool. This hypothesis was evaluated directly by measuring the basal efflux and electrically-evoked release of endogenous DA and dihydroxyphenylacetic acid (DOPAC). In striatal slices from reserpine-treated rabbits A increased DA efflux, reduced DOPAC efflux, and inhibited electrically-evoked /sup 3/H-ACh release in a concentration-dependent manner. These effects could not be mimicked by inhibition of neuronal uptake or MAO, but were blocked by inhibition of DA synthesis or neuronal uptake, and were potentiated by inhibition of MAO. In slices with intact vesicular transmitter stores A induced DA efflux was 2-fold greater than that seen in slices having no vesicular stores. Inhibition of DA synthesis reduced A-induced DA efflux by 60%, but had little effect on the ability of A to inhibit /sup 3/H-ACh release. A also increased the electrical stimulation-evoked overflow of DA (an effect which was attenuated slightly by synthesis inhibition), and potently inhibited DOPAC overflow. These results suggest that: 1) A facilitates efflux of axoplasmic DA by an accelerated exchange diffusion mechanism. The releasable axoplasmic pool is derived from newly synthesized and vesicular transmitter pools; 2) postsynaptic indices of transmitter release may be misleading; and 3) A increases electrically-evoked DA release possibly by inhibiting neuronal uptake.

Groundwater Resources of Ribeira Paul Basin, Island of Santo Antao, Cape Verde, West Africa  

USGS Publications Warehouse

Groundwater resources in Cape Verde provide water for agriculture, industry, and human consumption. These resources are limited and susceptible to contamination. Additional groundwater resources are needed for continued agricultural development, particularly during times of drought, but increased use and (or) climatic change may have adverse effects on the quantity and quality of freshwater available. In volcanic island aquifers such as those of Cape Verde, a lens of fresh groundwater typically ?floats? upon a layer of brackish water at the freshwater/saltwater boundary, and increased pumping may cause salt water intrusion or other contamination. A recent U.S. Geological Survey study assessed baseline groundwater conditions in watersheds on three islands of Cape Verde to provide the scientific basis for sustainably developing water resources and minimizing future groundwater depletion and contamination.

Abstract Among Neotropical microhylids, the genus Chiasmocleis is exceptionally diverse. Most species of Chiasmocleis were described in recent years based on external morphology, but recent studies using molecular data did not support the monophyly of the species groups clustered based on feet webbing. Furthermore, a phylogeographic study of C. lacrimae estimated high genetic divergence and low gene flow among populations across small geographic ranges. Increasing the molecular and geographic sampling, and incorporating morphological data, we identified new cryptic species. Herein, we used novel genetic and morphological data to describe a new species of Chiasmocleis. PMID:25161370

Myelin management by the 18.5kDa and 21.5kDa classic myelin basic protein isoforms  

PubMed Central

The classic myelin basic protein (MBP) splice isoforms range in nominal molecular mass from 14 to 21.5 kDa, and arise from the gene in the oligodendrocyte lineage (Golli) in maturing oligodendrocytes. The 18.5-kDa isoform that predominates in adult myelin adheres the cytosolic surfaces of oligodendrocyte membranes together, and forms a two-dimensional molecular sieve restricting protein diffusion into compact myelin. However, this protein has additional roles including cytoskeletal assembly and membrane extension, binding to SH3-domains, participation in Fyn-mediated signaling pathways, sequestration of phosphoinositides, and maintenance of calcium homeostasis. Of the diverse post-translational modifications of this isoform, phosphorylation is the most dynamic, and modulates 18.5-kDa MBPs protein-membrane and protein-protein interactions, indicative of a rich repertoire of functions. In developing and mature myelin, phosphorylation can result in microdomain or even nuclear targeting of the protein, supporting the conclusion that 18.5-kDa MBP has significant roles beyond membrane adhesion. The full-length, early-developmental 21.5-kDa splice isoform is predominantly karyophilic due to a non-traditional P-Y nuclear localization signal, with effects such as promotion of oligodendrocyte proliferation. We discuss in vitro and recent in vivo evidence for multifunctionality of these classic basic proteins of myelin, and argue for a systematic evaluation of the temporal and spatial distributions of these protein isoforms, and their modified variants, during oligodendrocyte differentiation.

Characteristics of 26 kDa antigen of H. Pylori by Monoclonal Antibody.  

PubMed

Alkylhydroperoxide reductase (AhpC, the 26 kDa antigen) is one of the abundant antioxidant enzymes in Helicobacter pylori and seems to have a good potential for use in development of immunoassays to detect H. pylori infection in clinical specimens. This study aimed to investigate some properties of this antigen by the produced monoclonal antibodies. Five established hybridoma cell lines secreting monoclonal antibodies (MAbs) against 26 kDa antigen of H. pylori were cultivated and MAbs were purified by affinity chromatography. Subsequently, MAbs were conjugated with biotin, and different combinations of capture and tracer antibodies used in sandwich ELISA. Immunoblotting of bacterial extracts were performed to estimate aggregation status of the antigen. Release of antigen from the cultivated bacteria on solid media was examined by sandwich ELISA, and also, existence of interference in fecal extract was investigated by immunoblotting and sandwich ELISA. Our findings showed that the MAbs against 26 kDa antigen of H. pylori could recognize three bands of nearly 25 kDa, 50 kDa, and 75 kDa in immunoblotting. This study also indicated presence of more antigens in the culture medium around the bacteria than the bacterial extract itself. The results of sandwich ELISA and immunoblotting on fecal extracts suggest the presence of interfering agents that prevent detection of antigen by antibody in ELISA but not in immunoblotting. In this study the oligomerization of the 26 kDa antigen, presence of interfering agents in stool matrix, and release of antigen to outside of bacteria, were demonstrated. PMID:25530147

Metagonimus yokogawai: a 100-kDa somatic antigen commonly reacting with other trematodes.  

PubMed

This study was undertaken to characterize the properties of a 100 kDa somatic antigen from Metagonimus yokogawai. Monoclonal antibodies (mAbs) were produced against this 100 kDa antigen, and their immunoreactivity was assessed by western blot analysis with patients' sera. The mAbs against the 100 kDa antigen commonly reacted with various kinds of trematode antigens, including intestinal (Gymnophalloides seoi), lung (Paragonimus westermani), and liver flukes (Clonorchis sinensis and Fasciola hepatica). However, this mAb showed no cross-reactions with other helminth parasites, including nematodes and cestodes. To determine the topographic distribution of the 100 kDa antigen in worm sections, indirect immunoperoxidase staining was performed. A strong positive reaction was observed in the tegumental and subtegumental layers of adult M. yokogawai and C. sinensis. The results showed that the 100 kDa somatic protein of M. yokogawai is a common antigen which recognizes a target epitope present over the tegumental layer of different trematode species.

Mycobacterium tuberculosis 38kDa antigen and its encoding gene-experience in diagnostic applications.  

PubMed

Our experience has revealed that the detection of 38 kDa antigen or antibody to the antigen in various fluids is useful in diagnosis of various mainfestations of tuberculosis. The PCR developed for 340bp sequence of its encoding gene also shows a high degree of sensitivity and specificity. Thus the 38 kDa antigen/antibody combination or the PCR are ideal for development of kits for diagnosis. These immunoassays to be successful, isolation of the 38 kDa antigen in large quantities is essential. Using recombinant DNA technology and expression inE. coli this has been achieved. However, such recombinant antigen does not have the same immunological properties as the native antigen and hence not suitable in immunodiagnosis. To fully realise the potential of the MoAb defined antigens such as the 38 kDa antigen, 19 kDa antigen and others it is essential to devise alternative vector-host systems that help in glycosylation, do not accumulate as inclusion bodies and can be isolated with less damage.

Low strain, long life creep fatigue of AF2-1DA and INCO 718  

NASA Technical Reports Server (NTRS)

Two aircraft turbine disk alloys, GATORIZED AF2-DA and INCO 718 were evaluated for their low strain long life creep-fatigue behavior. Static (tensile and creep rupture) and cyclic properties of both alloys were characterized. The cntrolled strain LCF tests were conducted at 760 C (1400 F) and 649 C (1200 F) for AF2-1DA and INCO 718, respectively. Hold times were varied for tensile, compressive and tensile/compressive strain dwell (relaxation) tests. Stress (creep) hold behavior of AF2-1DA was also evaluated. Generally, INCO 718 exhibited more pronounced reduction in cyclic life due to hold than AF2-1DA. The percent reduction in life for both alloys for strain dwell tests was greater at low strain ranges (longer life regime). Changing hold time from 0 to 0.5, 2.0 and 15.0 min. resulted in corresponding reductions in life. The continuous cycle and cyclic/dwell initiation failure mechanism was predominantly transgranular for AF2-1DA and intergranular for INCO 718.

Essential 170-kDa subunit for degradation of crystalline cellulose by Clostridium cellulovorans cellulase.  

PubMed Central

The cellulase complex from Clostridium cellulovorans has been purified and its subunit composition determined. The complex exhibits cellulase activity against crystalline cellulose as well as carboxymethylcellulase (CMCase) and cellobiohydrolase activities. Three major subunits are present with molecular masses of 170, 100, and 70 kDa. The 100-kDa subunit is the major CMCase, although at least four other, minor subunits show CMCase activity. The 170-kDa subunit has the highest affinity for cellulose, does not have detectable enzymatic activity, but is necessary for cellulase activity. Immunological studies indicate that the 170-kDa subunit is not required for binding of the catalytic subunits to cellulose and therefore does not function solely as an anchor protein. Thus this core subunit must have multiple functions. We propose a working hypothesis that the binding of the 170-kDa subunit converts the crystalline cellulose to a form that is capable of being hydrolyzed in a cooperative fashion by the associated catalytic subunits.

Fluorescence spectroscopy coupled with PARAFAC and PLS DA for characterization and classification of honey.  

PubMed

Fluorescence spectroscopy coupled with parallel factor analysis (PARAFAC) and Partial least squares Discriminant Analysis (PLS DA) were used for characterization and classification of honey. Excitation emission spectra were obtained for 95 honey samples of different botanical origin (acacia, sunflower, linden, meadow, and fake honey) by recording emission from 270 to 640nm with excitation in the range of 240-500nm. The number of fluorophores present in honey, excitation and emission spectra of each fluorophore, and their relative concentration are determined using a six-component PARAFAC model. Emissions from phenolic compounds and Maillard reaction products exhibited the largest difference among classes of honey of different botanical origin. The PLS DA classification model, constructed from PARAFAC model scores, detected fake honey samples with 100% sensitivity and specificity. Honey samples were also classified using PLS DA with errors of 0.5% for linden, 10% for acacia, and about 20% for both sunflower and meadow mix. PMID:25577082

Effects of ?-Da1a a peptidic ?1A-adrenoceptor antagonist in human isolated prostatic adenoma and anaesthetized rats  

PubMed Central

Background and Purpose ?-Da1a, a 65 amino-acid peptide, has subnanomolar affinity and high selectivity for the human ?1A-adrenoceptor subtype. The purpose of this study was to characterize the pharmacological effects of ?-Da1a on prostatic function, both in vivo and in vitro. Experimental Approach ?-Da1a was tested as an antagonist of adrenaline-induced effects on COS cells transfected with the human ?1A-adrenoceptor as well as on human isolated prostatic adenoma obtained from patients suffering from benign prostatic hyperplasia. Moreover, we compared the effects of ?-Da1a and tamsulosin on phenylephrine (PHE)-induced increases in intra-urethral (IUP) and arterial pressures (AP) in anaesthetized rats, following i.v. or p.o. administration. Key Results On COS cells expressing human ?1A-adrenoceptors and on human prostatic strips, ?-Da1a inhibited adrenaline- and noradrenaline-induced effects. In anaesthetized rats, ?-Da1a and tamsulosin administered i.v. 30 min before PHE significantly antagonized the effects of PHE on IUP. The pKB values for tamsulosin and ?-Da1a for this effect were similar. With regards to AP, ?-Da1a only reduced the effect of PHE on AP at the lowest dose tested (10 ?gkg?1), whereas tamsulosin significantly reduced PHE effects at doses between 10 and 150 ?gkg?1. Conclusions and Implications ?-Da1a exhibited a relevant effect on IUP and a small effect on AP. In contrast, tamsulosin antagonized the effects of PHE on both IUP and AP. We conclude that ?-Da1a is more uroselective than tamsulosin. ?-Da1a is the most selective peptidic antagonist for ?1A-adenoceptors identified to date and could be a new treatment for various urological diseases.

Identification of an abundant 56 kDa protein implicated in food allergy as granule-bound starch synthase.  

PubMed

Rice, the staple food of south and east Asian counties, is considered to be hypoallergenic. However, several clinical studies have documented rice-induced allergy in sensitive patients. Rice proteins with molecular weights of 14-16, 26, 33, and 56 kDa have been identified as allergens. Recently, it was documented that the 56 kDa rice allergen was responsible for rice-induced anaphylaxis. The 14-16 kDa allergens have been identified as ?-amylase inhibitors; the 26 kDa protein has been identified as ?-globulin; and the 33 kDa protein has been identified as glyoxalase I. However, the identity of the 56 kDa rice allergen has not yet been determined. In this study, we demonstrate that serum from patients allergic to maize shows IgE binding to a 56 kDa protein that was present in both maize and rice but not in the oil seeds soybean and peanut. The 56 kDa IgE-binding protein was abundant in the rice endosperm. We have purified this protein from rice endosperm and demonstrated its reactivity to IgE antibodies from the serum of maize-allergic patients. The purified protein was subjected to matrix-assisted laser desorption ionization-time of flight-tandem mass spectrometry analysis, resulting in identification of this rice allergen as granule-bound starch synthase, a product of the Waxy gene. Immunoblot analysis using protein extracts from a waxy mutant of rice revealed the absence of the 56 kDa IgE-binding protein. Our results demonstrate that the 56 kDa rice allergen is granule-bound starch synthase and raise the possibility of using waxy mutants of rice as a potential source of the hypoallergenic diet for patients sensitized to the 56 kDa rice allergen.

Pharmacokinetics of chlorogenic acid and corydaline in DA-9701, a new botanical gastroprokinetic agent, in rats.  

PubMed

1.Few studies describing the pharmacokinetic properties of chlorogenic acid (CA) and corydaline (CRD) which are marker compounds of a new prokinetic botanical agent, DA-9701, have been reported. The aim of the present study is to evaluate the pharmacokinetic properties CA and CRD following intravenous and oral administration of pure CA (1-8?mg/kg) or CRD (1.1-4.5?mg/kg) and their equivalent dose of DA-9701 to rats. 2.? Dose-proportional AUC and dose-independent clearance (10.3-12.1?ml/min/kg) of CA were observed following its administration. Oral administration of CA as DA-9701 did not influence the oral pharmacokinetic parameters of CA. Incomplete absorption of CA, its decomposition in the gastrointestinal tract, and/or pre-systemic metabolism resulted in extremely low oral bioavailability (F) of CA (0.478-0.899%). 3.? CRD showed greater dose-normalized AUC in the higher dose group than that in lower dose group(s) after its administration due to saturation of its metabolism via decreased non-renal clearance (by 51.3%) and first-pass extraction. As a result, the F of CRD following 4.5?mg/kg oral CRD (21.1%) was considerably greater than those of the lower dose groups (9.10 and 13.8%). However, oral administration of CRD as DA-9701 showed linear pharmacokinetics as a result of increased AUC and F in lower-dose groups (by 182% and 78.5%, respectively) compared to those of pure CRD. The greater oral AUC of CRD for DA-9701 than for pure CRD could be due to decreased hepatic and/or GI first-pass extraction of CRD by other components in DA-9701. PMID:24417753

Solubilization of insoluble inorganic phosphate by Burkholderia cepacia DA23 isolated from cultivated soil  

PubMed Central

A mineral phosphate solubilizing bacterium, Burkholderia cepacia DA23 has been isolated from cultivated soils. Phosphate-solubilizing activities of the strain against three types of insoluble phosphate were quantitatively determined. When 3% of glucose concentration was used for carbon source, the strain had a marked mineral phosphate-solubilizing activity. Mineral phosphate solubilization was directly related to the pH drop by the strain. Analysis of the culture medium by high pressure liquid chromatography identified gluconic acid as the main organic acid released by Burkholderia cepacia DA23. Gluconic acid production was apparently the result of the glucose dehydrogenase activity and glucose dehydrogenase was affected by phosphate regulation. PMID:24031195

Detection and differentiation of 22kDa and 20kDa Growth Hormone proteoforms in human plasma by LC-MS/MS.  

PubMed

Human growth hormone (GH) is suspected to be widely and illegally used in sport to improve athletes' performance. For the detection of GH abuse, blood samples are screened for abnormal ratios between the 22 and 20kDa GH proteoforms that demonstrate the administration of the synthetic hormone. Current detection methods are based on classical immunoassays as they provide sufficient sensitivity for the detection of GH proteoforms. These antibody based methods, however, suffer from unclear selectivity and potential cross-reactivity towards similar proteins. For unambiguous GH detection, we report a Mass Spectrometry ImmunoAssay (MSIA) that first enriches GH from plasma with an antibody of relatively low specificity, and subsequently quantifies the 22 and 20kDa proteoforms by Selected Reaction Monitoring (SRM) LC-MS/MS analysis. This method proved superior to an antibody-free strategy based on GH purification by protein precipitation. Using GH-MSIA we successfully quantified the 22/20kDa GH ratio in post-exercise capillary plasma extracted from two individuals. This GH-MSIA is applicable to anti-doping and GH-related disease analysis. PMID:25556001

Efeitos do binarismo no resolvido na determinao da funo de massa de aglomerados  

NASA Astrophysics Data System (ADS)

Atravs de simulaes numricas buscamos quantificar os efeitos que o binarismo no resolvido causa na determinao da funo de massa (MF) de aglomerados estelares. Geramos diagramas cor-magnitude (CMDs) artificiais simulando uma populao nica, caracterizada por estrelas de mesma idade e composio qu mica, com uma frao de binrias no resolvidas e distribuio em massa das estrelas dada por uma MF do tipo lei de potncia. A presena de pares de estrelas no resolvidos faz com que a MF obtida da funo de luminosidade (LF) tenha a tndencia de ser mais plana do que a MF que gerou o CMD artificial. Propomos um tratamento de correo para tal efeito. Outro efeito relacionado diz respeito ao alargamento do CMD, que apresenta-se como um indicador do nmero total de estrelas no dom nio de baixas massas (m < 0.6M). Todos os resultados acima possuem uma forte dependncia com os erros fotomtricos e esto baseados na hiptese de que ambas estrelas do par no resolvido so sorteadas de uma mesma MF de forma independente. O objetivo final aplicarmos o tratamento aqui desenvolvido para implementarmos a anlise da nossa amostra de aglomerados ricos da Grande Nuvem de Magalhes.

A inclinao do extremo de baixa luminosidade a da funo de luminosidade desses grupos foi estimado atravs de simulaes de Monte Carlo. O mtodo consistiu em simular galxias ans de baixo brilho superficial em imagens reais seguindo uma distribuio de magnitudes dada uma funo de Schechter. Foram testados vrios modelos com diferentes valores para os parmetros M* e a da funo de Schechter, e para cada um dos modelos foi repetido o mesmo processo de recuperao, seleo e anlise usados com as galxias ans dos grupos. Os resultados de cada modelo foram ento comparados com o observado nos grupos. Nossos resultados indicam que a distribuio de magnitudes (para magnitudes absolutas at MR»-12) observadas nos grupos so compatveis com uma funo de luminosidade de Schechter dada por um M* = -16 e um a entre -1.0 e -1.4, e portanto de acordo com a tendncia observada de uma inclinao do extremo de baixa luminosidade da funo de luminosidade de grupos mais plana (~1.2, Trentham & Tully 2002, MNRAS, 335, 712) que esperado pelo modelo hierrquico de formao de estruturas CDM (Cold Dark Matter - Matria Escura Fria).

Stress and Failure Analysis of Rapidly Rotating Asteroid (29075) 1950DA  

NASA Astrophysics Data System (ADS)

Rozitis et al. recently reported that near-Earth asteroid (29075) 1950 DA, whose bulk density ranges from 1.0 g cm3 to 2.4 g cm3, is a rubble pile and requires a cohesive strength of at least 44-76 Pa to keep from failing due to its fast spin period. Since their technique for giving failure conditions required the averaged stress over the whole volume, it discarded information about the asteroid's failure mode and internal stress condition. This paper develops a finite element model and revisits the stress and failure analysis of 1950 DA. For the modeling, we do not consider material hardening and softening. Under the assumption of an associated flow rule and uniform material distribution, we identify the deformation process of 1950 DA when its constant cohesion reaches the lowest value that keeps its current shape. The results show that to avoid structural failure the internal core requires a cohesive strength of at least 75-85 Pa. It suggests that for the failure mode of this body, the internal core first fails structurally, followed by the surface region. This implies that if cohesion is constant over the whole volume, the equatorial ridge of 1950 DA results from a material flow going outward along the equatorial plane in the internal core, but not from a landslide as has been hypothesized. This has additional implications for the likely density of the interior of the body.

Differentiation of Pueraria lobata and Pueraria thomsonii using partial least square discriminant analysis (PLS-DA).  

PubMed

The aims of the study were to differentiate Pueraria lobata from its related species Pueraria thomsonii and to examine the raw herbal material used in manufacturing kudzu root granules using partial least square discriminant analysis (PLS-DA). Sixty-four raw materials of P. lobata and P. thomsonii and kudzu root-labelled granules were analysed by ultra performance liquid chromatography. To differentiate P. lobata from P. thomsonii, PLS-DA models using the variables selected from the entire chromatograms, genetic algorithm (GA), successive projection algorithm (SPA), puerarin alone and six selected peaks were employed. The models constructed by GA and SPA demonstrated superior classification ability and lower model's complexity as compared to the model based on the entire chromatographic matrix, whilst the model constructed by the six selected peaks was comparable to the entire chromatographic model. The model established by puerarin alone showed inferior classification ability. In addition, the PLS-DA models constructed by the entire chromatographic matrix, GA, SPA and the six selected peaks showed that four brands out of seventeen granules were mislabelled as P. lobata. In conclusion, PLS-DA is a promising procedure for differentiating Pueraria species and determining raw material used in commercial products. PMID:23777642

Rapid and efficient preparation of monoclonal antibodies against 35 kDa lipoprotein of Mycoplasma penetrans.  

PubMed

To develop a rapid and efficient method for preparing monoclonal antibodies (MAb) against 35 kDa lipoprotein of Mycoplasma penetrans, BALB/c mice were injected into the footpads for immunization, and the popliteal lymph nodes were isolated 19 days later for MAb-producing hybridomas, from which the mAbs against the 35 kDa lipoprotein were screened. The identification of the mAb against the 35 kDa lipoprotein was performed using indirect enzyme-linked immunosorbent assay (ELISA) and immunoblotting. Using popliteal lymph node procedures, we generated several positive clones, one of which we characterized by ELISA and immunoblot. The clone 1D41B8 was identified as the immunoglobulin G1 (IgG1) isotype, kappa chain with affinity constants (Ka) of 2.95 x 10(9) M(-1). The MAbs did not cross-react with a number of control bacteria, which included Mycoplasma fermentans, Mycoplasma hominis, and Mycoplasma genitalium. This is the first report on the preparation of mAbs against M. penetrans that is specific to 35 kDa lipoprotein using popliteal lymph nodes. The high-specificity and high-affinity MAbs produced by two methodologies used of hybridomas provide a basis for further research on the pathogenesis and early diagnosis of M. penetrans. This simple approach may become a method of choice for the generation and production of MAbs in a short period of time. PMID:17451357

A rigorous error analysis of D\\/A conversion with dynamic element matching  

Microsoft Academic Search

A known approach to reducing harmonic distortion in D\\/A converters involves a technique called dynamic element matching, The idea is not to reduce the power of the overall conversion error but rather to give it a random, noise-like structure. By reducing the correlation among successive samples of the conversion error, harmonic distortion is reduced. This paper presents the first rigorous
