    ERIC Educational Resources Information Center

    Schachter, Ron

    2009-01-01

    Mayoral control of public schools is nothing new. Boston pioneered the practice in 1992, replacing elected school committee members with mayoral appointees. Since then, a dozen urban districts--including Cleveland, Chicago, New York City, and Washington, D.C.--have undergone a similar change in school governance that has shifted some or most of…

    Eggers, William D.

    1993-01-01

    Although the plight of cities seems nearly hopeless, three new-style big city mayors have emerged to try ideas deserving study by other cities. Edward Rendell of Philadelphia (Pennsylvania), John Norquist of Milwaukee (Wisconsin), and Stephen Goldsmith of Indianapolis (Indiana) are demonstrating that U.S. cities can be made to work. (SLD)

  4. Mayoral Governance and Student Achievement: How Mayor-Led Districts Are Improving School and Student Performance

    ERIC Educational Resources Information Center

    Wong, Kenneth K.; Shen, Francis X.

    2013-01-01

    Mayoral control and accountability is one of very few major education reforms that aim at governance coherence in this nation's highly fragmented urban school systems. A primary feature of mayoral governance is that it holds the office of the mayor accountable for school performance. As an institutional redesign, mayoral governance integrates…

    Center for the Study of Education Policy, 2009

    2009-01-01

    The past two decades have seen an emerging trend in urban school governance: mayors taking the reins of school district leadership. The impetus for putting the mayor in charge of a city's schools usually stems from at least one of the following being documented or generally perceived about an urban school district: (1) Lack of accountability; (2)…

    ERIC Educational Resources Information Center

    Rossell, Christine

    1977-01-01

    Successful, or at least nonviolent, strategy for school desegregation depends upon the city's social and political structure. Mayors should plan school desegregation policy as part of a total approach to urban renewal. (Author/GC)

    NASA Astrophysics Data System (ADS)

    Papanikolau, N.

    Welcome by the Mayor of Valtetsi Mr. Chairman Ladies and Gentlemen The municipality of Valtetsi welcomes you and wishes success in your work. Arcadia is both a historical and modern region. Moreover, as a name it remained in the western culture recalling a harmonious and peaceful dream, a lost and desirable situation where the human being lived in balance with nature, a region where the person did not feel yet uprooted. For thousands of years the poetic voices retained vivid this eternal bucolic call of simplicity and accessible happiness. Gazing the starlit sky we will always see Kallisto, the daughter of Lykaona, king of Arcadia and her son Arcadian as they were both transformed in to the constellations Major and Minor Ursus because of the erotic libido of Jupiter and the jealousy of Hera. And we will always remember Centaurus Cheirona, the great schoolteacher of ancient heroes, who was the first to name the constellations according to mythology. Finally we would like to thank the patriot Mr. T. Tzioumi who returns to his beautiful village in Arcadia just like Antaios did. In the geographic place that inspired the arcadian ideal, such activities recall in the limelight Arcadia as was dreamed by Europe. Mr. Chairman, ladies and gentlemen, success in your scientific work. The Municipality of Valtetsi and I myself will be always next to you so that your stay at Arcadia will always remain vivid in your memory. Thank you. Nikos Papanikolaou Mayor of Valtetsi

  14. Some problems of Maryland towns as seen by their mayors

    NASA Technical Reports Server (NTRS)

    Peake, H. J.

    1978-01-01

    Conversations were held with the mayors of six Maryland towns to discuss possible models and needs for technology transfer. An unexpected outcome of the discussions was a considerable insight into local problems as perceived by the mayors. Problems, whether administrative, socio-economic, or technological, are different, from town to town, in degree, not in kind. Recognition of this feature of local priorities is vital to any considerations of external assistance.

  15. Taxas de eventos para as fontes astrofísicas do detector Mario Schenberg

    NASA Astrophysics Data System (ADS)

    Castro, C. S.; Araujo, J. C. N.; Miranda, O. D.; Aguiar, O. D.

    2003-08-01

    O detector de ondas gravitacionais Mario Schenberg será sensível a sinais que cheguem à Terra com amplitude h~10-21 e dentro da faixa em frequências que varia de 3,0 a 3,4 kHz. As principais fontes astrofísicas em condições de gerar um sinal detectável pela antena Schenberg são: colapsos estelares que produzam eventos do tipo supernova; instabilidades hidrodinâmicas em estrelas de nêutrons; excitação dos modos fluído (modos f) de estrelas de nêutrons; excitação dos primeiros modos quadrupolares de buracos negros com massa ~ 3,8 M¤; coalescências de estrelas de nêutrons e buracos negros em sistemas binários e, ainda, espiralações de mini-buracos negros. Neste trabalho nós determinamos as taxas de eventos para o Schenberg associadas a dois tipos de fontes: através da de-excitação dos modos f de estrelas de nêutrons e através da coalescência de mini-buracos negros de 0,5 M¤ (que atualmente têm sido colocados como possíveis candidatos a objetos massivos do halo Galáctico). Nós mostramos que esses tipos de fontes poderão produzir sinais em ondas gravitacionais com uma taxa em torno de um evento por ano dentro da banda do Schenberg.

  18. Evolution of a Quaternary peralkaline volcano: Mayor Island, New Zealand

    USGS Publications Warehouse

    Houghton, B.F.; Weaver, S.D.; Wilson, C.J.N.; Lanphere, M.A.

    1992-01-01

    Mayor Island is a Holocene pantelleritic volcano showing a wide range of dispersive power and eruptive intensity despite a very limited range in magma composition of only 2% SiO2. The primary controls on this range appear to have been the magmatic gas content on eruption and a varying involvement of basaltic magma, rather than major-element chemistry of the rhyolites. The ca. 130 ka subaerial history of the volcano contains portions of three geochemical cycles with abrupt changes in trace-element chemistry following episodes of caldera collapse. The uniform major-element chemistry of the magma may relate to a fine balance between rates of eruption and supply and the higher density of the more evolved (Ferich) magmas which could be tapped only after caldera-forming events had removed significant volumes of less evolved but lighter magma. ?? 1992.

  1. Eventos de Desconexao na Cauda de Plasma do Cometa P/Halley

    NASA Astrophysics Data System (ADS)

    Voelzke, M. R.; Fahr, H. J.

    2001-08-01

    Observacoes cometárias e de vento solar sao comparadas com o propósito de determinar-se as condicoes do vento solar associadas aos eventos de desconexao (DEs) observados em caudas de plasma cometárias. Os dados cometários sao provenientes do The International Halley Watch Atlas of Large-Scale Phenomena. A análise visual sistemática das imagens do atlas revelou, entre outras estruturas morfológicas, 47 DEs ao longo da cauda de plasma do P/Halley. Estes 47 DEs registrados em 47 imagens distintas permitiram a descoberta de 19 origens de DEs, ou seja, o tempo em que as desconexoes iniciaram foi calculado. Os dados do vento solar sao provenientes de medidas feitas in situ pela sonda espacial IMP-8, as quais foram usadas para elaborar a variacao da velocidade do vento solar, densidade e pressao dinâmica durante o intervalo analisado. O presente trabalho compara as atuais teorias conflitantes, baseadas nos mecanismos de formacao, com o intuito de explicar o fenômeno cíclico dos DEs, ou seja, os efeitos de producao iônica, os efeitos de pressao e os efeitos de reconexao magnética sao analisados. Para cada uma das 19 origens de DEs comparou-se a densidade com a respectiva velocidade do vento solar com o intuito de determinar-se uma possível correlacao entre estas origens e os efeitos de pressao dinâmica. Quando da ocorrência de 6 origens de DEs o IMP-8 nao realizou medidas, nos outros 13 casos 10 origens (77%) mostraram uma anticorrelacao entre velocidade e densidade e apenas 3 (23%) revelaram uma tendência similar entre velocidade e densidade. Portanto, a análise inicial demonstra uma fraca correlacao entre as origens dos DEs e os efeitos de pressao.

    Existen prejuicios en relación con la vejez, incluso entre los profesionales que se dedican a la gerontología. Uno común y peligroso es considerar que los viejos son todos enfermos o discapacitados. La relación médico-paciente es la piedra angular de la práctica y ética médicas. Para alcanzar el respeto por los adultos mayores es necesaria una medicina prudente, basada en una práctica en la cual la reflexión ética y clínica pueda contribuir. Esto último es posible si se hacen valer los derechos del adulto mayor, en particular como paciente para la toma de decisiones. PMID:20379380

    Introduccion La diabetes mellitus y las demencias constituyen dos problemas crecientes de salud entre la población adulta mayor del mundo y en particular de los paises en desarrollo. Hacen falta estudios longitudinales sobre el papel de la diabetes como factor de riesgo para demencia. Objetivo Determinar el riesgo de demencia en sujetos Mexicanos con diabetes mellitus tipo 2. Materiales y Metodos Los sujetos diabéticos libres de demencia pertenecientes al Estudio Nacional de Salud y Envejecimiento en México fueron evaluados a los dos años de la línea de base. Se estudió el papel de los factores sociodemográficos, de otras comorbilidades y del tipo de tratamiento en la conversión a demencia. Resultados Durante la línea de base 749 sujetos (13.8%) tuvieron diabetes. El riesgo de desarrollar demencia en estos individuos fue el doble (RR, 2.08 IC 95%, 1.59–2.73). Se encontró un riesgo mayor en individuos de 80 años y más (RR 2.44 IC 95%, 1.46–4.08), en los hombres (RR, 2.25 IC 95%, 1.46–3.49) y en sujetos con nivel educativo menor de 7 años. El estar bajo tratamiento con insulina incrementó el riesgo de demencia (RR, 2.83, IC 95%, 1.58–5.06). Las otras comorbilidades que aumentaron el riesgo de demencia en los pacientes diabéticos fueron la hipertensión (RR, 2.75, IC 95%, 1.86–4.06) y la depresión (RR, 3.78, 95% IC 2.37–6.04). Conclusión Los sujetos con diabetes mellitus tienen un riesgo mayor de desarrollar demencia, La baja escolaridad y otras comorbilidades altamente prevalentes en la población Mexicana contribuyen a la asociación diabetes-demencia.

    2012-02-10

    Large [moment magnitude (M(w)) ? 7] continental earthquakes often generate complex, multifault ruptures linked by enigmatic zones of distributed deformation. Here, we report the collection and results of a high-resolution (?nine returns per square meter) airborne light detection and ranging (LIDAR) topographic survey of the 2010 M(w) 7.2 El Mayor-Cucapah earthquake that produced a 120-kilometer-long multifault rupture through northernmost Baja California, Mexico. This differential LIDAR survey completely captures an earthquake surface rupture in a sparsely vegetated region with pre-earthquake lower-resolution (5-meter-pixel) LIDAR data. The postevent survey reveals numerous surface ruptures, including previously undocumented blind faults within thick sediments of the Colorado River delta. Differential elevation changes show distributed, kilometer-scale bending strains as large as ~10(3) microstrains in response to slip along discontinuous faults cutting crystalline bedrock of the Sierra Cucapah.

  2. Mud volcano response to the 4 April 2010 El Mayor-Cucapah earthquake

    NASA Astrophysics Data System (ADS)

    Rudolph, M. L.; Manga, M.

    2010-12-01

    Mud volcanoes sometimes respond to earthquakes, but the mechanisms by which earthquakes trigger changes in ongoing eruptions or initiate new eruptions are not completely understood. We measured gas discharge at a field of mud volcanoes near the Salton Sea, southern California, before and after the 4 April 2010 El Mayor-Cucapah earthquake and observed an increase in gas flux immediately following the earthquake and a subsequent recovery to pre-earthquake values. This earthquake-eruption pair is of particular interest because the earthquake produced large strains, up to 1.2%, near the mud volcano location, allowing us to test two competing triggering mechanisms: (1) shaking-induced bubble mobilization and (2) permeability enhancement. We measured the rheology of erupted mud from the mud volcanoes to quantify the importance of mechanism 1 and found that this mechanism is unlikely to be important. We therefore favor the explanation that the increased gas flux was caused by a transient increase in permeability.

  3. Did stresses from the Cerro Prieto Geothermal Field influence the El Mayor-Cucapah rupture sequence?

    NASA Astrophysics Data System (ADS)

    Trugman, Daniel T.; Borsa, Adrian A.; Sandwell, David T.

    2014-12-01

    The Mw 7.2 El Mayor-Cucapah (EMC) earthquake ruptured a complex fault system in northern Baja California that was previously considered inactive. The Cerro Prieto Geothermal Field (CPGF), site of the world's second largest geothermal power plant, is located approximately 15 km to the northeast of the EMC hypocenter. We investigate whether anthropogenic fluid extraction at the CPGF caused a significant perturbation to the stress field in the EMC rupture zone. We use Advanced Land Observing Satellite interferometric synthetic aperture radar data to develop a laterally heterogeneous model of fluid extraction at the CPGF and estimate that this extraction generates positive Coulomb stressing rates of order 15 kPa/yr near the EMC hypocenter, a value which exceeds the local tectonic stressing rate. Although we cannot definitively conclude that production at the CPGF triggered the EMC earthquake, its influence on the local stress field is substantial and should not be neglected in local seismic hazard assessments.

  4. Getting food policy on the Mayoral table: a comparison of two election cycles in New York and London.

    PubMed

    Freudenberg, N; Atkinson, S

    2015-04-01

    Cities and Mayors are increasingly being recognized as important in shaping social policy and improving social well-being. And municipal food policies are increasingly important as a tool to reduce food insecurity and prevent diet-related chronic diseases. Thus city governments have a unique ability to improve local food environments. To realize this potential for improving urban food environments, nutrition advocates will need to find innovative approaches for influencing municipal food policy. This paper examines Mayoral elections as a vehicle to advance food policy. To explore this strategy, Mayoral elections in two cities, New York City (NYC) and London, during two recent cycles were compared. To gather evidence multiple sources were used including campaign documents, media and opinion polls as well as the authors' own observations as food policy observers and participants in the two cities. Mayoral governance differs between NYC and London, with the Mayor in NYC having greater powers of management and administration, whilst the London Mayor has a more strategic role and may need to also use 'influence'. Food policy and related issues did not feature strongly in the first election cycles in either city. However by the 2012 and 2013 elections food issues were definitely 'on the table' and featured in main candidates' campaign literature. These latter elections also saw the importance of food advocates coming together to form common alliances and place food issues higher on the municipal agenda. In this way, food policy has become part of the election dialogue in both cities and candidates are expected to consider food policy issues. This analysis leads to make observations which could guide advocates as to how to use Mayoral elections to raise policy objectives for the benefit of public health. PMID:25834929

    The surface rupture produced on April 4th of 2010 by the M 7.2 El Mayor-Cucapah Earthquake is an ideal target to be analyzed by remote sensing techniques. It produced over 100 km of scarps, with vertical and horizontal slip on the order of 2 to 3 m in scarcely vegetated, rugged terrain underlain by mostly igneous rocks. A 3D displacement field (DF) was calculated by matching pre- to post-event airborne LiDAR point clouds through the Iterative Closest Point (ICP) algorithm, which first segments the point clouds into discrete windows, and for each, iteratively converges on a rigid body transformation comprising a translation and a rotation that best aligns the pre- to post-event point clouds. After testing different window sizes, we used a square window 100m a side. The El Mayor-Cucapah LiDAR data sets present special challenges for the ICP technique. The point clouds differ considerably in point density, by ~1:700. This, and the lower precision of the pre-earthquake data, limit the accuracy of the DF results. Despite these issues, the vertical and East-West (E-W) components of the DF from ICP very clearly delineate the trace of the surface rupture, showing east-side down dextral-normal motion in agreement with field measurements and the focal mechanism reported for this event. A systematic error in the LiDAR instrument used for the pre-event survey caused severe distortion of the North-South (N-S) component of the LiDAR returns. After reprocessing the source pre-event point cloud in various ways to correct for the systematic error, a more plausible pattern for the N-S component was obtained for the DF. To have another perspective for the horizontal DF, a subpixel correlation analysis of optical satellite images (SPOT 2.5 m panchromatic images) before and after the earthquake, was performed using the COSI-Corr software. We combined the N-S component from this analysis with the E-W and vertical components of the ICP results, and present the analysis of the resulting DF. We also compare the results from ICP and COSI-Corr individually for each of the horizontal components. Both methods delineate very clearly the rupture, and agree in direction with small discrepancies in magnitude for the horizontal DF. Results from far field deformation measurements obtained from different remote sensing techniques, such as GPS and InSAR, could be fused with the near-field LiDAR and COSI-Corr results to provide a synoptic view of the strain induced by earthquakes such as the El Mayor-Cucapah event.

    Aseismic deformation processes such as fault creep, viscous flow, and pore fluid motion influence the states of stress on fault zones, making them important in regional seismic hazard assessment. A large earthquake imparts stress changes to the surrounding medium that can accelerate these processes, producing transient surface deformation that can yield valuable information about them. The Salton Trough is an ideal site in which to use this method to study the rheological structure of extensional environments: the extensional component of relative plate motion there has thinned the continental lithosphere and brought the asthenosphere up to within 45 km of the surface, while the transform component of relative motion produces large strike-slip earthquakes that impart large stress changes to this shallow asthenosphere. The most recent such earthquake, the 2010 M=7.2 El Mayor-Cucapah event, was the largest earthquake in this region since at least 1892 and occurred directly above shallow asthenosphere. Using the Wei et al [2011] slip model for the El Mayor-Cucapah event and the deformation modeling software RELAX, we simulate postseismic surface deformation resulting from afterslip and viscoelastic relaxation in a variety of hypothetical geometries, then compare these forward models to postseismic displacements observed in GPS data. We observe a broad pattern of westward postseismic displacement in the Peninsular Ranges that is consistent with linear Newtonian viscoelastic relaxation in a low-viscosity asthenosphere. Displacement timeseries in the eastern Imperial Valley suggest that a power-law rheology may also be present in at least the shallow Salton Trough asthenosphere. A systematic pattern of postseismic uplift in the Imperial Valley is also best explained by viscoelastic relaxation in the asthenosphere and/or mantle lithosphere. Near-field horizontal displacements in the Imperial Valley feature both a short-term decaying signal consistent with power-law viscoelastic relaxation or deep afterslip and a notable sustained signal consistent with Newtonian viscoelastic relaxation in the lower crust and/or mantle lithosphere. The best-fitting models feature complex, laterally heterogeneous assortments of many of these mechanisms, suggesting that high heat flow in the Salton Trough results in reduced viscosities in both the crust and upper mantle.

    Background Bioflocculants effect the aggregation of suspended solutes in solutions thus, a viable alternative to inorganic poly-ionic and synthetic organic flocculants which are associated with deleterious health problems. Consequently, a consortium of two bacteria species were evaluated for optimized bioflocculant yield following the inadequacies of axenic cultures. Results 16S rDNA nucleotide sequencing and BLAST analysis of nucleotide sequences were used to identify the bacterial species, carbon and nitrogen sources optimally supporting bioflocculant production were assessed and the purified bioflocculant characterized. Nucleotide sequences showed 97% and 96% similarity to Methylobacterium sp. AKB-2008-KU9 and Methylobacterium sp. strain 440. The second isolate, likewise, showed 98% similarity to Actinobacterium OR-221. The sequences were deposited in GenBank as Methylobacterium sp. Obi [accession number HQ537130] and Actinobacterium sp. Mayor [accession number JF799090]. Flocculating activity of 95% was obtained in the presence of Ca2+ and heat-stability was exhibited with retention of above 70% activity at 100°C in 30 min. In addition, bioflocculant yield was about 8.203 g/l. A dose of 1 mg/ml of purified bioflocculant was optimal for the clarification of Kaolin suspension (100 ml) following Jar test. FTIR spectrum revealed the presence of carboxyl and hydroxyl functional groups amongst others. Conclusions The mixed culture produced bioflocculant with high flocculating activity and an improved yield. The efficiency observed with jar test may imply industrial applicability. PMID:23915393

  10. The Mayor of EarthCube: Cities as an Analogue for Governing Cyberinfrastructure

    Historical development of national and global infrastructure follows common paths with common imperatives. The nascent development may be led a by champion, innovator, or incubating organization. Once the infrastructure reaches a tipping point and adoption spreads rapidly, the organization and governance evolves in concert. Ultimately, no wide-spread infrastructure (from canals to highways to the electric grid to radio/television, or the Internet) operates with a single overarching governing body. The NSF EarthCube initiative is a prototype implementation of cyberinfrastructure, using the broad geoscience community as the testbed. Governance for EarthCube is emulating the pattern of other infrastructure, which we argue is a system of systems that can be described by organized complexity, emergent systems, and non-linear thermodynamics. As we consider governance cyberinfrastructure in the geosciences, we might look to cities as analogs: cities provide services such as fire, police, water, and trash collection. Cities issue permits and often oversee zoning, but much of what defines cities is outside the direct control of city government. Businesses choose whether to locate there, where to operate, and what to build. Residents make similar decisions. State and federal agencies make decisions or impose criteria that greatly affect cities, without necessarily getting agreement from them. City government must thus operate at multiple levels - providing oversight and management of city services, interaction with residents, businesses, and visitors, and dealing with actions and decisions made by independent entities over which they have little or no control. Cities have a range of organizational and management models, ranging from city managers, councils, and weak to strong mayors, some elected directly, some chosen from councils. The range and complexity of governance issues in building, operating, and sustaining cyberinfrastructure in the geosciences and beyond, rival those of running a medium to large city. The range of organizational and management structures in meeting community needs and goals are also diverse and may embody a multi-faceted set of governing archetypes, best suited to carry out each of myriad functions. We envision cyberinfrastructure governance to be a community-driven enterprise empowered to carry out a dynamic set of functions, operating within a set of processes (comparable to a city charter) and guiding principles (constitution).

  11. Postseismic Deformation Following the 2010 El Mayor-Cucapah Earthquake: Observations, Kinematic Inversions, and Dynamic Models

    Due to its location on a transtensional section of the Pacific-North American plate boundary, the Salton Trough is a region featuring large strike-slip earthquakes within a regime of shallow asthenosphere, high heat flow, and complex faulting, and so postseismic deformation there may feature enhanced viscoelastic relaxation and afterslip that is particularly detectable at the surface. The 2010 El Mayor-Cucapah earthquake was the largest shock in the Salton Trough since 1892 and occurred close to the US-Mexico border, and so the postseismic deformation recorded by the continuous GPS network of southern California provides an opportunity to study the rheology of this region. Three-year postseismic transients extracted from GPS displacement time-series show four key features: (1) 1-2 cm of cumulative uplift in the Imperial Valley and 1 cm of subsidence in the Peninsular Ranges, (2) relatively large cumulative horizontal displacements 150 km from the rupture in the Peninsular Ranges, (3) rapidly decaying horizontal displacement rates in the first few months after the earthquake in the Imperial Valley, and (4) sustained horizontal velocities, following the rapid early motions, that were still visibly ongoing 3 years after the earthquake. Kinematic inversions show that the cumulative 3-year postseismic displacement field can be well fit by afterslip on and below the coseismic rupture, though these solutions require afterslip with a total moment equivalent to at least a earthquake and higher slip magnitudes than those predicted by coseismic stress changes. Forward modeling shows that stress-driven afterslip and viscoelastic relaxation in various configurations within the lithosphere can reproduce the early and later horizontal velocities in the Imperial Valley, while Newtonian viscoelastic relaxation in the asthenosphere can reproduce the uplift in the Imperial Valley and the subsidence and large westward displacements in the Peninsular Ranges. We present two forward models of dynamically coupled deformation mechanisms that fit the postseismic transient well: a model combining afterslip in the lower crust, Newtonian viscoelastic relaxation in a localized zone in the lower crust beneath areas of high heat flow and geothermal activity, and Newtonian viscoelastic relaxation in the asthenosphere; and a second model that replaces the afterslip in the first model with viscoelastic relaxation with a stress-dependent viscosity in the mantle. The rheology of this high-heat-flow, high-strain-rate region may incorporate elements of both these models and may well be more complex than either of them.

    The April 4th, 2010 Mw 7.2 earthquake was the largest earthquake in over 100 years of known historical seismicity in the Salton Trough region. It was a relatively benign earthquake, with only two deaths related to its occurrence. It produced, however, profound agricultural and ecological changes at the southern section of the Mexicali Valley, where a new fault called the Indiviso fault, is shown to have ruptured by analysis of ALOS PALSAR and Landsat imagery. The Indiviso fault connects the ridge-transform and continental transform tectonic regimes with a straight linkage, as revealed by this earthquake, but this event also simultaneously involved oblique normal faulting and cross-faulting. The earthquake was complex, with at least three distinct slip pulses. It originated as a normal rupture along the ~18 km long, N-S striking El Mayor-Hardy fault along the east margin of the Sierra El Mayor. After 10 seconds, two large bursts of energy were released, one to the NW and one to the SE, producing the total moment release equivalent to Mw 7.25. The NW ruptures reactivated portions of the Pescadores, Borrego and Paso Superior faults with minor slip along the Laguna Salada and several other faults. This section had a dominant right lateral strike slip sense of motion with the NE side down. To the SE of the epicenter, disruption occurred along the dominantly strike-slip Indiviso fault, with a SW side down component of dip slip. The epicentral aftershock area, including its main aftershock to the NW, is >120 km in length; the surficial faulting occurs along ~110 km with 6-9 km of splaying to the N-NE at the NW end and to the S-SW at the SE end. The El Mayor Cucapah - Indiviso event follows nine M>6.5 earthquakes along the San Andreas fault system in the past 80 years between the head of the Gulf of California and the Transverse Ranges. Long, straight fault segments capable of larger earthquakes, and that have not ruptured historically, include portions of the San Jacinto and Elsinore faults, and the entire southern San Andreas Fault.

    531 imagens contidas no The International Halley Watch Atlas of Large-Scale Phenomena (Brandt et al., 1992) cobrindo o período de setembro de 1985 a julho de 1986 foram analisadas visando identificar, caracterizar as propriedades e correlacionar estruturas morfológicas da cauda de plasma do cometa P/Halley. A análise revelou 47 eventos de desconexão (DEs) (Niedner & Brandt, 1979; Jockers, 1985; Celnik et al., 1988; Delva et al., 1991). A análise completa de todas as imagens encontra-se publicada em Voelzke & Matsuura, 1998. A distribuição dos DEs na distância heliocêntrica apresenta um caráter bimodal possivelmente associado com a distribuição espacial das fronteiras de setor magnético do meio interplanetário. Os 47 DEs fotografados em 47 imagens distintas permitiram determinar 19 origens de DEs, ou seja, o instante em que supostamente o cometa cruzou a fronteira entre setores magnéticos do vento solar. Tais dados cometários foram comparados com dados do vento solar provenientes de medidas realizadas in situ pelas sondas IMP-8, ICE e PVO, que mediram a variação da velocidade do vento solar, da densidade e da pressão dinâmica durante o intervalo analisado. Os dados destas sondas espaciais em conjunto com os da sonda Vega 1 foram usados para determinar o tempo das passagens do lençol de corrente. Com base nos dados das sondas foram calculadas as coordenadas heliográficas retroativas do lençol de corrente na "superfície fonte" dos mapas sinóticos do campo magnético de Hoeksema, 1989. O cálculo retroativo é feito através de um modelo simples de expressão do vento solar com velocidade uniforme, sendo considerada a co-rotação da magnetosfera com o Sol. Este trabalho apresenta os resultados desta comparação e a análise cinemática da origem dos DEs, determinada sob a hipótese que o plasma desconectado de um dado DE afasta-se com velocidade constante do núcleo cometário (Voelzke & Matsuura, 1998) e compara esta análise com outras que determinam o tempo de desconexão a partir de um movimento linear constantemente acelerado (Yi et al., 1994). A velocidade de um DE para outro varia enormemente. - Brandt, J.C., Niedner, M.B.Jr. and Rahe, J., (1992) The International Halley Watch Atlas of Large-Scale Phenomena (printed by: Johnson Printing Co., Boulder, CO), University of Colorado-Boulder. - Celnik, W.E., Koczet, P., Schlosser, W., Schulz, R., Svejda, P. and Weissbauer, K., (1988) Astron.

    The Colorado River Delta region of southern Imperial Valley, California, and Mexicali Valley, Baja California, is a tectonically dynamic area characterized by numerous active faults and frequent large seismic events. Significant earthquakes that have been accompanied by surface fault rupture and/or soil liquefaction occurred in this region in 1892 (M7.1), 1915 (M6.3; M7.1), 1930 (M5.7), 1940 (M6.9), 1950 (M5.4), 1957 (M5.2), 1968 (6.5), 1979 (6.4), 1980 (M6.1), 1981 (M5.8), and 1987 (M6.2; M6.8). Following this trend, the M7.2 El Mayor-Cucapah earthquake of April 4, 2010, ruptured approximately 120 kilometers along several known faults in Baja California. Liquefaction caused by the M7.2 El Mayor-Cucapah earthquake was widespread throughout the southern Imperial Valley but concentrated in the southwest corner of the valley, southwest of the city centers of Calexico and El Centro where ground motions were highest. Although there are few strong motion recordings in the very western part of the area, the recordings that do exist indicate that ground motions were on the order of 0.3 to 0.6g where the majority of liquefaction occurrences were found. More distant liquefaction occurrences, at Fites Road southwest of Brawley and along Rosita Canal northwest of Holtville were triggered where ground motions were about 0.2 g. Damage to roads was associated mainly with liquefaction of sandy river deposits beneath bridge approach fills, and in some cases liquefaction within the fills. Liquefaction damage to canal and drain levees was not always accompanied by vented sand, but the nature of the damage leads the authors to infer that liquefaction was involved in the majority of observed cases. Liquefaction-related damage to several public facilities - Calexico Waste Water Treatment Plant, Fig Lagoon levee system, and Sunbeam Lake Dam in particular - appears to be extensive. The cost to repair these facilities to prevent future liquefaction damage will likely be prohibitive. As such, it is likely that liquefaction will recur at these facilities during the next large earthquake in this area.

    Whether static or dynamic triggering is the dominant mechanism for triggering aftershocks in near field is currently under heated debate. Previous studies on earthquake triggering mostly examined seismicity rate changes around the occurrence time of large earthquakes based on existing earthquake catalogs. However, such catalogs could be incomplete immediately after the mainshock, which may cause apparent seismicity rate changes that are unrelated to stress changes. In this study, we examine seismicity rate changes around the Salton Sea geothermal region following the 2010 Mw7.2 El Mayor-Cucapah earthquake in Baja California. We focus on this region mainly because of its abundant background seismicity, dense network coverage, and being in the apparent stress shadow of the mainshock, which is the key factor to differentiate static and dynamic triggering. According to the Southern California Seismic Network (SCSN) catalog, the seismicity rate near Salton Sea clearly increased immediately after the mainshock and dropped below the pre-mainshock level within a few days. The seismicity remains low for another few months before returning back to the pre-mainshock level. To check whether such patterns are caused by catalog incompleteness, we are currently applying a waveform-based matched filter technique to detect possible missing events around Salton Sea that were masked by rigorous aftershock sequence around the mainshock rupture region. With more completed catalog, we can identify the genuine seismicity rate changes for better comparison with the static and dynamic stress changes. In addition to seismicity rate, static and dynamic stress changes could also affect seismic velocity in the upper crust, with a pattern that is somewhat similar to seismicity rate changes. Thus, monitoring seismic velocity changes can further help to differentiate the triggering mechanisms. In our preliminary study, we apply the ambient noise cross-correlation technique to continuously monitor the seismic velocity near Salton Sea ten days before and after the El Mayor-Cucapah earthquake. We find that immediately after the mainshock, seismic velocity near Salton Sea reduced up to 0.4% and followed by a fast recovery in the next three days. From 5 to 10 days after the mainshock, the velocity changes remained ~0.2% lower than the pre-shock level. Such co-seismic decrease was most likely caused by the widespread damages induced by strong ground motion, suggesting that dynamic stress changes were dominant in the short term. We are currently applying the same technique at later times to check whether the velocity change returns back to the pre-mainshock or not.

    Among the many preserved sound artefacts deposited in the offerings of the Aztec Templo Mayor are a set of ten tubular duct flutes made from clay, dating Late Postclassic Mesoamerica, 1350-1521 AD. The aerophones are completely painted in blue, and characterized by: (1) a short mouthpiece; (2) a framed aperture; (3) a tube with four fingerholes; and (4) an applicated mask with features of the Aztec rain god Tlaloc, basically three rings and a standardized relief structure of two clouds. While all measurements follow the same pattern, one particular organological distinction was made, as five flutes show an exit hole in the middle ring of the mask and five flutes are stopped. Thus, five instruments sound considerably higher, apart from the minimal pitch deviation of each specimen. Both the tonal capacity of each flute and the acoustics of several flutes played simultaneously were recorded and measured. A series of remarkable interference effects could be produced, which were strongly related to the ritual complex reflected in the offering. Taking in consideration the Aztec concept of music, it could be supposed that they were perceived as a principle of the song, or proper voice of Tlaloc.

    We detect and precisely locate over 9500 aftershocks that occurred in the Yuha Desert region during a 2 month period following the 4 April 2010 Mw 7.2 El Mayor-Cucapah (EMC) earthquake. Events are relocated using a series of absolute and relative relocation procedures that include Hypoinverse, Velest, and hypoDD. Location errors are reduced to ~40 m horizontally and ~120 m vertically.Aftershock locations reveal a complex pattern of faulting with en echelon fault segments trending toward the northwest, approximately parallel to the North American-Pacific plate boundary and en echelon, conjugate features trending to the northeast. The relocated seismicity is highly correlated with published surface mapping of faults that experienced triggered surface slip in response to the EMC main shock. Aftershocks occurred between 2 km and 11 km depths, consistent with previous studies of seismogenic thickness in the region. Three-dimensional analysis reveals individual and intersecting fault planes that are limited in their along-strike length. These fault planes remain distinct structures at depth, indicative of conjugate faulting, and do not appear to coalesce onto a throughgoing fault segment. We observe a complex spatiotemporal migration of aftershocks, with seismicity that jumps between individual fault segments that are active for only a few days to weeks. Aftershock rates are roughly consistent with the expected earthquake production rates of Dieterich (1994). The conjugate pattern of faulting and nonuniform aftershock migration patterns suggest that strain in the Yuha Desert is being accommodated in a complex manner.

    The realization of national climate change commitments, as agreed through international negotiations, requires local action. However, data is still insufficient to make accurate statements about the scale of urban emissions (UNHABITAT, 2011). The need of comparable emission inventories at city level, including smaller cities, is widely recognized to develop evidence-based policies accounting for the relation between emissions and institutional, socio-economic and demographic characteristics at city level. This paper presents a collection of harmonized greenhouse gases (GHG) emission inventories (the "CoM sample 2013") at municipal level directly computed by the cities and towns that participate in the EU Covenant of Mayors initiative. This is the mainstream European movement of local and regional authorities who voluntarily commit to reduce GHG emissions by 20 % or more by 2020. The "CoM sample 2013" (http://edgar.jrc.ec.europa.eu/com/data/index.php?SECURE=123, doi:10.2904/EDGARcom2013) has been carefully checked to ensure its internal consistency and its congruity with respect to internationally accepted guide values for emission factors. Overall, it provides valuable data for the analysis of the heterogeneity of final energy consumption and greenhouse gas emissions of cities.

    Triggered slip in the Yuha Desert area occurred along more than two dozen faults, only some of which were recognized before the April 4, 2010, El Mayor-Cucapah earthquake. From east to northwest, slip occurred in seven general areas: (1) in the Northern Centinela Fault Zone (newly named), (2) along unnamed faults south of Pinto Wash, (3) along the Yuha Fault (newly named), (4) along both east and west branches of the Laguna Salada Fault, (5) along the Yuha Well Fault Zone (newly revised name) and related faults between it and the Yuha Fault, (6) along the Ocotillo Fault (newly named) and related faults to the north and south, and (7) along the southeasternmost section of the Elsinore Fault. Faults that slipped in the Yuha Desert area include northwest-trending right-lateral faults, northeast-trending left-lateral faults, and north-south faults, some of which had dominantly vertical offset. Triggered slip along the Ocotillo and Elsinore Faults appears to have occurred only in association with the June 14, 2010 (Mw5.7), aftershock. This aftershock also resulted in slip along other faults near the town of Ocotillo. Triggered offset on faults in the Yuha Desert area was mostly less than 20 mm, with three significant exceptions, including slip of about 50–60 mm on the Yuha Fault, 40 mm on a fault south of Pinto Wash, and about 85 mm on the Ocotillo Fault. All triggered slips in the Yuha Desert area occurred along preexisting faults, whether previously recognized or not.

    We report newly available data sets and preliminary analysis of ground- and airborne-lidar surveys of the 4 April 2010 El Mayor-Cucapah earthquake rupture. The hyperarid setting and varied surficial geology of this complex rupture zone presents an ideal setting to advance the use of lidar in post-earthquake scientific response. Terrestrial lidar surveys commenced within two weeks of the earthquake and capture ephemeral geomorphic features of the rupture zone. We recorded approximately 2 km of rupture on the Borrego fault where oblique dextral slip approaches four meters. These data highlight fine-scale features such as centimeter-scale scarps, subtle warping of the ground surface, and striations on the exposed fault free-face. Airborne lidar surveys, collected mid-August, 2010, span the rupture zone for 100 km in a NW-SE direction, from just south of the international border to the tidal flats of the Colorado River delta at the head of the Gulf of California. 3.8 billion point measurements were obtained with an average density of 11 points per square meter. GPS ground control was provided from a combination of PBO stations north of the border and coordination with the occupation of post-earthquake campaign sites in the central and southern portions of the rupture zone. The 3 km average width of the survey captures the complexity of strain-transfer between the multiple fault segments that slipped in 2010, as well as the adjacent zone of surface ruptures attributed to the 1892 Laguna Salada earthquake. This data set provides a new basis for offset measurements to be compared against field data collected immediately following the 2010 earthquake. Quantitative comparison to lower-resolution, pre-event lidar collected by the Instituto Nacional de Estadística y Geografía (INEGI) illuminates near-field distributed vertical deformation adjacent to the fault rupture. The southeastern half of the lidar survey spans a zone of cryptic dextral deformation, hosted within the thick sedimentary fill, where little surface evidence of tectonic deformation has been recovered to date. Here the lidar reveals a few linear zones of warping and minor surface ruptures that are likely faults. However the majority of dextral slip here appears to have been absorbed by distributed deformation of the sediments.

    Virtual globes are becoming ubiquitous for visualizing the Earth and other planets. However, as earth scientists pursue methods to visually explore and interpret earth surface processes using sub-meter pixel resolution digital elevation models (DEM) and imagery data spanning large areas, limitations of the commonly used virtual globes have emerged. We developed Crusta as an alternative virtual globe that allows users to investigate such data by conducting interactive, real-time, virtual field mapping. Crusta represents the globe as a 30-sided polyhedron to avoid distortion, in particular, the singularities at the poles characteristic of other projections. Each side can be subdivided to an arbitrarily fine grid to accommodate DEM and image data of arbitrary resolution. A convenient pre-processing tool based on the GDAL library facilitates importing a number of data formats into the Crusta-specific multi-scale hierarchical format. We designed Crusta with a focus on dynamic, interactive exploration of data: vertical exaggeration, shading, color ramp application, and display, generation and editing of decorated vector lines are supported in real time, directly on the virtual 3D landscape. These powerful visualization and interaction capabilities enable fluid and intuitive exploration, assist discovery and interpretation, and provide detailed feature mapping. Currently, we are using Crusta to investigate LiDAR data collected after the 4 April 2010, Mw7.2 El Mayor-Cucapah earthquake in northern Mexico. We have generated a single dataset comprised of multiple layers of finer DEMs embedded in coarser ones: 1) tripod LiDAR covering about 2 km of the rupture zone at 3 cm/pixel; 2) aerial LiDAR covering almost the entire rupture zone (over 300 km2) at 50 cm/pixel; 3) ASTER 30 m/pixel over the California/Mexico border region; 4) NASA's BlueMarble Next Generation over the whole globe at about 500 km/pixel. The interactive capabilities of Crusta to visually explore this dataset and create accurate, high-quality 3D geologic maps of the fresh, meter-scale coseismic surface ruptures has potential to advance understanding of how earthquakes deform the Earth's surface.

  5. Timing and controls on late Quaternary landscape development along the eastern Sierra El Mayor range front in northern Baja California, Mexico

    The Sierra El Mayor-Sierra Cucapá mountain range in northern Baja separates the Colorado River delta from the Laguna Salada Basin and is important in terms of understanding the structural transition from the northern Gulf Extensional Province to the San Andreas system. One of the principal Quaternary landscape features of the eastern Sierra El Mayor-Sierra Cucapá is a prominent surface that slopes ~ 1-2° eastward towards the Colorado River Delta. Along the eastern side of the Sierra El Mayor and facing the Colorado River delta, but not along other piedmont mountain fronts that face the delta, this surface is terminated by a series of stepped terrace surfaces. The terrace surfaces are cut into fluvial-deltaic deposits from the Colorado River delta system and are capped by ~ 1 m thick gravels. Optically stimulated luminescence ages from interbedded coarse sands in the capping gravels of the upper surface and two of the inset terraces range from ~ 17 to 31 ka (average 24 ± 3 ka) but lack a systematic age trend from upper to lower surface. The underlying fluvial-deltaic deposits have older optically stimulated luminescence ages of 31 to 39 ka and suggest Colorado River delta deposition during the relatively stable interstadial of the Middle Wisconsinan substage (Marine Isotope Stage 3) when sea level was ca - 60 to - 80 m. Samples from depth-profiles in the capping gravels and from the top of the upper surface have a mean 10Be terrestrial cosmogenic nuclide age of 59 ± 5 ka. When corrected for inheritance, an average age of ~ 21 ka is computed for exposure of the capping gravels on the upper surface and inset terraces, which is in the range of the optically stimulated luminescence burial ages. Both the upper surface and inset terraces formed 17-30 ka at a transition time from dry to relatively wet climate when increased aggradation caused alluvial fan development on the upper surface. Regionally, these surfaces correlate with the Q2c-Q3a age deposits of the southwestern North America alluvial fan and terrace deposits. Sea level was also falling rapidly at this time, which may have caused the Colorado River to become entrenched near the range front thus allowing rapid response and down-cutting to form the inset terraces on the east side of the Sierra El Mayor facing the delta. Assuming the 34 ka delta deposits graded to a base level that was - 60 to - 80 m during Marine Isotope Stage 3, the computed surface uplift rate for the eastern side of the Sierra El Mayor is ~ 2.1-2.7 mm/yr. This uplift may be accommodated on a fault or fault system that is a southward extension of the Mexicali spreading and seismic zone that is buried beneath the Colorado River delta east of the Sierra El Mayor. The uplift rates from this study are consistent with geologic and geodetic data for the Sierra El Mayor and Sierra Cucapá, and account for much of the missing extensional strain across the area.

    Objetivos. Nos propusimos determinar el grado de preparación frente a los desastres naturales de los adultos mayores en los Estados Unidos y evaluar los factores que pueden afectar negativamente la salud y la seguridad durante este tipo de incidentes. Métodos. Obtuvimos una muestra de adultos de 50 años en adelante (n = 1 304) de la encuesta del 2010 del Estudio de la Salud y la Jubilación (HRS por su sigla en inglés). La encuesta recogió datos sobre las características demográficas generales, el estado de discapacidad o las limitaciones funcionales, y también sobre factores y comportamientos relacionados con la preparación frente a los desastres. Calculamos una puntuación global de preparación mediante indicadores individuales a fin de evaluar el grado de preparación general. Resultados. La media de la edad de los participantes (n = 1 304) fue de 70 años (desviación estándar [DE] = 9,3). Solo 34,3% informaron que habían participado en un programa formativo o que habían leído materiales sobre la preparación para los desastres. Casi 15% indicaron que usaban dispositivos médicos eléctricos que podían correr riesgo de no funcionar si se interrumpiera el suministro eléctrico. La puntuación de preparación indicó que la edad más avanzada, la discapacidad física y el menor nivel de escolaridad y de ingresos se asociaban independiente y significativamente a un grado de preparación general inferior. Conclusiones. A pesar de la mayor vulnerabilidad ante los desastres y del número cada vez mayor de adultos mayores en los Estados Unidos, muchos de los problemas sustanciales que encontramos son remediables y requieren atención en los sectores de la sociedad dedicados a la atención clínica, a la salud pública y al manejo de situaciones de emergencia.

  7. Recent benthic foraminifers as indicators of the sedimentary dynamics of the Tina Mayor and Tina Menor estuaries (S Bay of Biscay, N Spain)

    Recent benthic foraminifers from two estuaries in the North Spanish coastal region (Tina Mayor and Tina Menor) were analysed with the aim of characterising the ecology and dynamics of the different estuarine sub-environments. A total of 35 benthic foraminifer species were taxonomically determined in the Tina Mayor estuary, 22 of which contained living individuals during the sampling. For Tina Menor, there were 51 species, 30 of them biocenotic. The most abundant species in these estuaries were Ammonia tepida, Cribroelphidium williamsoni, Jadammina macrescens, Lobatula lobatula, Miliammina fusca, Rosalina globularis and Trochammina inflata. In Tina Menor, Haynesina germanica was also abundant. In the foraminifer assemblages, live (biocenotic) and dead (thanatocenotic) specimens were differentiated and processed statistically by a multivariate cluster-Q type analysis and detrended correspondence ordination analysis (DCA). Groupings of biocenotic assemblages were obtained for both estuaries indicating an ecologic separation of marine mouth, low and high marsh and zones with strong salinity oscillations in these estuaries. Thanatocenotic groupings, nevertheless, showed a different organisation of that of the ecologic groups, which were indicative of a transport of individuals from the mouth to the inner/mid estuary locations, along the main and/or secondary channels of these estuaries. Local differences between Tina Mayor and Tina Menor can be explained by the different physiographies of the estuary as a consequence of the different geological/sedimentological histories of both estuaries. Benthic foraminifer assemblages are distributed in the estuary following three zones: an outer estuary having marine characteristics with L. lobatula and R. globularis, a mid estuary, including a subtidal mudflat with variable salinity (A. tepida, C. williamsoni) and a marsh (J. macrescens, M. fusca and T. inflata), which is different in both estuaries. Tina Mayor is filled with more sediment, and it has a reduced mudflat and a large high marsh located above the MHW (Mean High Waters), where T. inflata is the species marker of the intervals between the MHW and MHWST (Mean High Waters Spring Tides) levels. In Tina Menor, estuary mudflats crossed with brackish secondary channels (with H. germanica) below MHWNT (Mean High Waters Neap Tides) are more developed, though the environments of low marsh with scarce vegetation (with M. fusca) are dominant in intervals between MHWNT and MHW. The relative abundance of M. fusca, particularly in the mid estuary, differentiates Tina Mayor and Tina Menor from other estuaries of Cantabria. Biocenotic and thanatocenotic assemblages show a general similarity in both estuaries (Sanders's index, > 70%). Samples with low similarity are evidence of the effect of post-mortem transport mostly produced by suspension. The percentage of exotic specimens is always less than 35%, supporting the mesotidal characteristic of both estuaries. The present results confirm the value of benthic foraminifers as markers of estuarine sub-environments, supporting their value for detecting changes in past estuarine environments.

    El estudio de la actividad solar con el telescopio para ondas submilimétricas (SST), nos permite, por vez primera, trabajar con una resolución temporal de milisegundos. Este hecho ha permitido observar emisión nunca antes comprobada, pulsos o flashes extremadamente rápidos provenientes de las regiones activas, los cuales parecen preanunciar fulguraciones en dichas regiones. Se muestra, como ejemplo, una fulguración observada con el telescopio HASTA en H?, y los pulsos rápidos que la preceden observados con el SST. Para cuantificar la influencia de la atmósfera terrestre en los datos registrados, se está estudiando la variabilidad temporal de las opacidades a las frecuecias de trabajo (212 y 405 Ghz), es decir los rangos de tiempo para los cuales la opacidad puede variar apreciablemente. Con este fin se calcula la eficiencia de cada canal multiplicada por la temperatura del Sol a estas frecuencias (estas son conocidas con una incerteza del 20 %). Se muestran los resultados obtenidos para cada canal, en donde se grafica este producto como función de la opacidad.

    4 April 2010 M 7.2 El Mayor-Cucapah earthquake that occurred in Baja California, Mexico and terminated near the U.S. Mexican border caused slip on the Imperial, Superstition Hills, and East Elmore Ranch Faults. The pattern of slip was observed using radar interferometry from NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) instrument collected on 20-21 October 2009 and 12-13 April 2010. Right-lateral slip of 36 ± 9 and 14 ± 2 mm occurred on the Imperial and Superstition Hills Faults, respectively. Left-lateral slip of 9 ± 2 mm occurred on the East Elmore Ranch Fault. The widths of the zones of displacement increase northward suggesting successively more buried fault motion to the north. The observations show a decreasing pattern of slip northward on a series of faults in the Salton Trough stepping between the El Mayor-Cucapah rupture and San Andreas Fault. Most of the motion occurred at the time of the M 7.2 earthquake and the UAVSAR observations are consistent with field, creepmeter, GPS, and Envisat observations. An additional 28 ± 1 mm of slip at the southern end of the Imperial Fault over a <1 km wide zone was observed over a 1 day span a week after the earthquake suggesting that the fault continued to slip at depth following the mainshock. The total moment release on the three faults is 2.3 × 1023-1.2 × 1024 dyne cm equivalent to a moment magnitude release of 4.9-5.3, assuming shallow slip depths ranging from 1 to 5 km.

    We present a review of our efforts to introduce astronomy as scientific career in Peru, showing how our astronomy outreach programs have been one of the most important keys to reach our national astronomical scientific goals, remarking the crucial role that the celebration of the IYA2009 must play, in order to promote PhD programmes in astronomy in developing countries. We show the importance of the creation of the Seminario Permanente de Astronomía y Ciencias Espaciales (SPACE) in the Universidad Nacional Mayor de San Marcos, as an academic scientific and cultural center in Peru, to support our 26 years-old "Astronomical Fridays” which are addressed to wide range of public, from schoolchildren to scientists. We also show how important was to rediscover our ancient astronomical cultural past of Incas in order to promote the construction of a Astronomical Center located near Cusco city over 4000 meters above sea level, which includes a tourist-educational observatory, a scientific optical observatory and a solar radio observatory.

    The M7.2 El Mayor-Cucapah earthquake of April 4, 2010 in Mexico’s Baja California caused extensive damage to the agricultural area of Mexicali Valley. The damage included wide-spread liquefaction and lateral spreading which destroyed or damaged irrigation canals. Without water, wheat, alfalfa, and other crops were lost. Fields were cut by fissures and partially buried by massive sand blows. Regional tilting from the earthquake was a serious issue for the gravity-controlled irrigation system. Ruptured canals and groundwater from sand blows flooded fields, roads, and towns. Flooding further damaged crops and brought contamination with it. Fissures and scarps through farm communities cracked buildings; ruptured water, sewer, and other pipelines; and made roads temporarily difficult to pass. Economically, farmers, seasonal farm workers, and agricultural suppliers were affected; reducing their ability to consume the goods and services of businesses unrelated to agriculture. Similar damage was observed in earlier earthquakes over the past 100 years. Society quickly forgets how the earth responds to strong shaking. We hope to provide a vivid portrait of this agricultural disaster so that other farming communities prone to strong seismic shaking may visualize what can happen from their own inevitable future earthquake. Fissure and sand blows southeast of Cucapah, Baja California, April 16, 2010. Heavily damaged irrigation canal northwest of Zacamoto, Baja California, April 15, 2010.

    In this manuscript, we introduce a framework for developing earthquake forecasts using Virtual Quake (VQ), the generalized successor to the perhaps better known Virtual California (VC) earthquake simulator. We discuss the basic merits and mechanics of the simulator, and we present several statistics of interest for earthquake forecasting. We also show that, though the system as a whole (in aggregate) behaves quite randomly, (simulated) earthquake sequences limited to specific fault sections exhibit measurable predictability in the form of increasing seismicity precursory to large m > 7 earthquakes. In order to quantify this, we develop an alert-based forecasting metric, and show that it exhibits significant information gain compared to random forecasts. We also discuss the long-standing question of activation versus quiescent type earthquake triggering. We show that VQ exhibits both behaviours separately for independent fault sections; some fault sections exhibit activation type triggering, while others are better characterized by quiescent type triggering. We discuss these aspects of VQ specifically with respect to faults in the Salton Basin and near the El Mayor-Cucapah region in southern California, USA and northern Baja California Norte, Mexico.

    Whether static or dynamic stress changes play the most important role in triggering earthquakes in the near field is still in debate. Here, we examine the seismicity rate changes in southern California following the 2010 Mw 7.2 El Mayor-Cucapah earthquake. We focus on the Salton Sea Geothermal Field (SSGF) and the San Jacinto Fault Zone (SJFZ) because of high-sensitivity continuous borehole recordings and ample background seismicity. A significant increase in seismic activity is found in both study regions immediately following the main shock. However, near the SSGF where the static Coulomb stress decreased, the seismicity rate dropped below the pre-main-shock rate after ˜1 month. In comparison, along the SJFZ with an increase in the static Coulomb stress, the seismicity rate remained higher than the background rate with several moderate-size earthquakes occurring in the subsequent months. While we cannot completely rule out other mechanisms, these observations are best consistent with a widespread increase in seismicity from dynamic stress changes immediately after the main shock, and longer term seismicity rate changes from static stress changes. Our observation, together with other recent studies, suggests that both static and dynamic stress changes are important in triggering near-field earthquakes, but their affected regions and timescales are different.

    El Mayor-Cucapah earthquake occurred on 4 April 2010 in northeastern Baja California just south of the U.S.-Mexico border. The earthquake ruptured several previously mapped faults, as well as some unidentified ones, including the Pescadores, Borrego, Paso Inferior and Paso Superior faults in the Sierra Cucapah, and the Indiviso fault in the Mexicali Valley and Colorado River Delta. We conducted several Global Positioning System (GPS) campaign surveys of preexisting and newly established benchmarks within 30 km of the earthquake rupture. Most of the benchmarks were occupied within days after the earthquake, allowing us to capture the very early postseismic transient motions. The GPS data show postseismic displacements in the same direction as the coseismic displacements; time series indicate a gradual decay in postseismic velocities with characteristic time scales of 66 ± 9 days and 20 ± 3 days, assuming exponential and logarithmic decay, respectively. We also analyzed interferometric synthetic aperture radar (InSAR) data from the Envisat and ALOS satellites. The main deformation features seen in the line-of-sight displacement maps indicate subsidence concentrated in the southern and northern parts of the main rupture, in particular at the Indiviso fault, at the Laguna Salada basin, and at the Paso Superior fault. We show that the near-field GPS and InSAR observations over a time period of 5 months after the earthquake can be explained by a combination of afterslip, fault zone contraction, and a possible minor contribution of poroelastic rebound. Far-field data require an additional mechanism, most likely viscoelastic relaxation in the ductile substrate.

    High-resolution surface topography is valuable for studying coseismic fault zone deformation and fault geometry. It enables us to measure three-dimensional surface displacements in earthquakes, as shown in recent studies that used light detection and ranging (lidar) to determine coseismic motion. However, the applicability of lidar is limited by its relatively high cost and low availability. In this study, we use the 2010 El Mayor-Cucapah earthquake to demonstrate the capability of Pleiades stereo imagery to measure coseismic vertical ground displacement. We acquired post-earthquake Pleiades tristereo imagery from backward, near-nadir, and forward orientations for a 45 km × 7 km portion of the epicentral area. One meter resolution digital elevation models (DEMs) were produced with the four different combinations of incidence angles and compared to the post-earthquake lidar DEM. Elevations from tristereo have slightly (˜15%) smaller uncertainties than bistereo as the tristereo DEM incorporates more observations. Elevation differences between the Pleiades and post-earthquake lidar DEMs show that the vertical accuracy of the Pleiades DEMs is ˜0.3 m. By differencing the Pleiades DEM and the pre-earthquake, 5 m resolution lidar DEM, we mapped meter and submeter offsets along the faults obtaining results comparable to a previous study that differenced the two lidar DEMs. This is the first case study of assessing very high resolution (VHR) satellite stereo imagery to determine submeter vertical ground displacement in an earthquake. By extension, we expect it to be possible to measure submeter vertical offsets occurring in earthquakes using pre-earthquake and post-earthquake VHR stereo imagery.

    The Mw 7.2 El Mayor-Cucapah earthquake (EMCE) of 4 April 2010 generated a ~110 km long, NW-SE trending rupture, with normal and right-lateral slip in the order of 2-3m in the Sierra Cucapah, the northern half, where the surface rupture has the most outstanding expression. Vertical and horizontal surface displacements produced by the EMCE have been addressed separately by other authors with a variety of aerial and satellite remote sensing techniques. Slip variation along fault and post-seismic scarp erosion and diffusion have been estimated in other studies using terrestrial LiDAR (TLS) on segments of the rupture. To complement these other studies, we computed the 3D deformation field by comparing pre- to post-event point clouds from aerial LiDAR surveys. The pre-event LiDAR with lower point density (0.013-0.033 pts m-2) required filtering and post-processing before comparing with the denser (9-18 pts m-2) more accurate post event dataset. The 3-dimensional surface displacement field was determined using an adaptation of the Iterative Closest Point (ICP) algorithm, implemented in the open source Point Cloud Library (PCL). The LiDAR datasets are first split into a grid of windows, and for each one, ICP iteratively converges on the rigid body transformation (comprising a translation and a rotation) that best aligns the pre- to post-event points. Testing on synthetic datasets perturbed with displacements of known magnitude showed that windows with dimensions of 100-200m gave the best results for datasets with these densities. Here we present the deformation field with detailed displacements in segments of the surface rupture where its expression was recognized by ICP from the point cloud matching, mainly the scarcely vegetated Sierra Cucapah with the Borrego and Paso Superior fault segments the most outstanding, where we are able to compare our results with values measured in the field and results from TLS reported in other works. EMC simulated displacement field for a 2m right lateral normal (east block down) slip on the pre-event point cloud along the Borrego fault on Sierra Cucapah.

    Very high-resolution (VHR) imagery can in principle measure surface topography with decimetric precision. The question is how well 3D mapping based on VHR stereo imagery is capable of capturing sub-metric height changes occurring in an earthquake, particularly those in remote areas? The aim of this study is to assess the capability of the Pleiades satellites to determine such height changes. We acquired Pleiades stereo imagery with backward (B), near-nadir (N) and forward (F) orientations over a 40 km × 5 km area in Baja California, Mexico, part of the epicentral area of the 2010 Mw 7.2 El Mayor-Cucapah earthquake. Coverage was chosen to coincide with the post-seismic LiDAR digital elevation model (DEM) for the area. DEMs have been produced with four different combinations of incidence angles (B-N, N-F, B-F and B-N-F). The raw point cloud has the lowest average density of ~0.7 points/m2 for B-F, ~1.0 points/m2 for B-N and N-F, and the greatest average density of ~3 points/m2 for tri-stereo (B-N-F). Compared to the post-earthquake LiDAR DEM, the Pleiades DEMs have a mean error of 1 m to 4 m, with a standard deviation of 0.5 m to 0.7 m. A series of topographic profiles from the Pleiades DEMs across the earthquake rupture were used to measure vertical offsets. These profiles show that the Pleiades DEM is capable of capturing vertical offsets of ~0.5 m. The measurements of vertical offsets from tri-stereo have smaller uncertainties than bi-stereo; this suggests that the tri-stereo DEM incorporating redundant observations is more robust and reliable. By differencing the 1-m tri-stereo Pleiades DEM and the pre-earthquake, lower-resolution (5-m) LiDAR DEM, we mapped metre and sub-metre offsets along the faults obtaining results comparable to a previous study that differenced the two LiDAR DEMs (Fig. 1). By extension, we expect it to be possible in similar settings to measure sub-metre vertical offsets occurring in earthquakes using pre- and post-event Pleiades stereo imagery.

  18. Simulation of Long-Period Ground Motion in the Imperial Valley Area during the Mw 7.2 El Mayor-Cucapah Earthquake

    2010-12-01

    The Mw 7.2 El Mayor-Cucapah mainshock of April 4 2010 caused significant long-period ground-motion in the Imperial Valley and Mexicali area, and was recorded by ~25 strong motion stations located on the Imperial Valley sediments. It provides an excellent opportunity to study wave propagation effects in deep sedimentary basins, to test the accuracy of the basin models, and to test our capabilities to predict long-period ground motion from numerical simulations. We have generated a series of dynamic rupture models constrained by fault geometry, hypocenter location and reported surface displacement, along a ~105km long stretch of the Borrego, Pescadores and Indiviso faults. Our rupture models feature surface slip of up to 2.0 m NW of the hypocenter, with buried slip under the Colorado River Delta SE of the hypocenter, emulated velocity strengthening in the near-surface, and generally subshear rupture speeds. Three of our rupture models show the following characteristics: (A) contains very limited slip (< 0.2 m) along the north-central part of the fault system where no surface rupture was observed; (B) has a more continuous slip distribution, but less slip toward the SE; and (C) is similar to model B, but with more slip in the hypocentral area. We simulate the wave propagation resulting from these three rupture models in the SCEC CVM4 on a 200x175x50 km3 grid that includes approximations of the Borrego, Pescadores and Indiviso faults, the Imperial Valley and the southern part of the Salton Sea. We use a spatial step of 100 m, which considering the minimum near-surface shear-wave velocity of 819 ms-1 (in the Imperial Valley sediments) allows us to model frequencies up to 1.5 Hz. Simulated spectral accelerations (SAs) at periods of 2s, 3s and 5s are generally consistent with the recorded strong motion data for all three rupture models. Observed SAs at 7s, however, are better reproduced by rupture models B and C than rupture model A. Velocity time histories recorded in the Imperial Valley are dominated by energetic surface waves with periods between 6 and 8 seconds, with 7s-SAs exceeding 0.10g at three sites. Synthetic time series exhibit amplification in the same period range, but often fail to reproduce the amplitude and duration of the observations. This suggests that shear-wave velocities in the velocity model and/or the applied Quality factors (Qs=50Vs, with Vs in kms-1) may need to be adjusted to reproduce the observations more accurately. Snapshots show that surface waves are generated predominantly at the basin edges near the NW end of the rupture in the simulations. These surface waves are then propagating NE across the Imperial basin, and serve as a possible explanation for the dominant long-period surface waves observed in the strong motion data. Furthermore, the coupling of source directivity and basin edge effects suggests that the simulated ground motion in the Imperial Valley is highly sensitive to near-surface peak slip rates near the NW end of the rupture.

  20. Analysis of Triggering of Earthquakes and Tremor in the Western U.S. due to the 2010 El Mayor Cucapah Earthquake and the Mw6.8 Mendocino Triple Junction Earthquake in 2014

    Recent studies indicate that the passage of seismic waves from large earthquakes are able to trigger small earthquakes and tremor at regional distances. These small events may be detected by applying a high-pass filter to seismograms to remove the much larger ground motion amplitudes from the large distant earthquake. Our interests are in examining the local triggering of earthquakes and tremor throughout the West Coast of North America from the magnitude 7.2 El Mayor-Cucapah 2010 earthquake and the magnitude 6.8 Northern California, March 10, 2014 earthquake, just north of the Mendocino Triple Junction. We will present the results of the analysis of waveform data from hundreds of seismometers throughout Southern California, Northern California, Oregon, Washington, as well as some stations bordering these states. Our preliminary results suggest that triggering of local earthquakes and tremor occurred for both earthquakes. In the case of the records of the Southern California stations for the El Mayor Cucapah 2010 earthquake, 27 stations showed triggering near the seismic station. 13 of these stations are located in or near known geothermal areas, while others were located along active faults and one offshore. While conducting this study, we detected an instrumental noise signal present in 63 of the Southern California seismograms for the El Mayor-Cucapah earthquake. Initially, the signal looked like a typical triggered event, yet with further investigation we found its likely cause to be instrumental noise. We plan to relate our observations of triggered seismicity and tremor to the tectonic environment to test the hypothesis that triggering and tremor most commonly occurs in volcanic and geothermal areas.

    The 4 April 2010 Mw 7.2 El Mayor-Cucapah (EMC) earthquake provides the best opportunity to date to study the lithospheric response to a large (>M6) magnitude earthquake in the Salton Trough region through analysis of Global Positioning System (GPS) data. In conjunction with the EarthScope Plate Boundary Observatory (PBO), we installed six new continuous GPS stations in the months following the EMC earthquake to increase station coverage in the epicentral region of northern Baja California, Mexico. We modeled the pre-EMC deformation field using available campaign and continuous GPS data for southern California and northern Baja California and inferred a pre-EMC secular rate at each new station location. Through direct comparison of the pre- and post-EMC secular rates, we calculate long-term changes associated with viscoelastic relaxation in the Salton Trough region. We fit these velocity changes using numerical models employing an elastic upper crustal layer underlain by a viscoelastic lower crustal layer and a mantle half-space. Forward models that produce the smallest weighted sum of squared residuals have an upper mantle viscosity in the range 4-6 × 1018 Pa s and a less well-resolved lower crustal viscosity in the range 2 × 1019 to 1 × 1022 Pa s. A high-viscosity lower crust, despite high heat flow in the Salton Trough region, is inconsistent with felsic composition and might suggest accretion of mafic lower crust associated with crustal spreading obscured by thick sedimentary cover.

    El objetivo principal del artículo es estudiar la asociación entre la percepción subjetiva sobre la situación económica propia y una serie de medidas objetivas de bienestar socioeconómico –fuentes de ingresos, tenencia de vivienda, nivel educativo y transferencias familiares informales de dinero- entre adultos mayores de dos países Latinoamericanos: México y Costa Rica. Los datos se obtienen de las primeras rondas de dos encuestas sobre envejecimiento: CRELES para Costa Rica y ENASEM para México. La variable dependiente más importante se obtiene de las respuestas a las pregunta “¿Cómo califica su situación económica actual?” en Costa Rica y “¿Diría usted que su situación económica es…?” en México. Para ambas encuestas, las respuestas se codificaron en forma binaria; el código 0 representa las categorías Excelente, Muy buena y Buena, y el código 1 representa a las categorías Regular y Mala. Se encontró que el ingreso por jubilación es un importante determinante de la percepción de bienestar en ambos países. En Costa Rica, el ingreso del cónyuge y la tenencia de vivienda son importantes predictores de la percepción de bienestar, mientras que en México, los ingresos por transferencias están fuertemente asociados con dicha percepción.

  6. Testing long-period ground-motion simulations of scenario earthquakes using the Mw 7.2 El Mayor-Cucapah mainshock: Evaluation of finite-fault rupture characterization and 3D seismic velocity models

    2011-01-01

    Using a suite of five hypothetical finite-fault rupture models, we test the ability of long-period (T>2.0 s) ground-motion simulations of scenario earthquakes to produce waveforms throughout southern California consistent with those recorded during the 4 April 2010 Mw 7.2 El Mayor-Cucapah earthquake. The hypothetical ruptures are generated using the methodology proposed by Graves and Pitarka (2010) and require, as inputs, only a general description of the fault location and geometry, event magnitude, and hypocenter, as would be done for a scenario event. For each rupture model, two Southern California Earthquake Center three-dimensional community seismic velocity models (CVM-4m and CVM-H62) are used, resulting in a total of 10 ground-motion simulations, which we compare with recorded ground motions. While the details of the motions vary across the simulations, the median levels match the observed peak ground velocities reasonably well, with the standard deviation of the residuals generally within 50% of the median. Simulations with the CVM-4m model yield somewhat lower variance than those with the CVM-H62 model. Both models tend to overpredict motions in the San Diego region and underpredict motions in the Mojave desert. Within the greater Los Angeles basin, the CVM-4m model generally matches the level of observed motions, whereas the CVM-H62 model tends to overpredict the motions, particularly in the southern portion of the basin. The variance in the peak velocity residuals is lowest for a rupture that has significant shallow slip (<5 km depth), whereas the variance in the residuals is greatest for ruptures with large asperities below 10 km depth. Overall, these results are encouraging and provide confidence in the predictive capabilities of the simulation methodology, while also suggesting some regions in which the seismic velocity models may need improvement.

    Aerial LiDAR surveys reconstruct with amazing fidelity the sinuosity of terrain relief. In this research we explore the 3D deformation field at the surface after a big earthquake (M7.2) by comparing pre- to post-event aerial LiDAR point clouds. The April 4 2010 earthquake produced a NW-SE surface rupture ~110km long with right-lateral normal slip up to 3m in magnitude over a very favorable target: scarcely vegetated and unaltered desert mountain range, sierras El Mayor and Cucapah, in northern Baja California, close to the US-México border. It is a plate boundary region between the Pacific and North American plates. The pre-event LiDAR with lower point density (0.013-0.033 pts m-2) required filtering and post-processing before comparing with the denser (9-18 pts m-2) more accurate post event dataset. The 3D surface displacement field was determined using an adaptation of the Iterative Closest Point (ICP) algorithm, implemented in the open source Point Cloud Library (PCL). The LiDAR datasets are first split into a grid of windows, and for each one, ICP iteratively converges on the rigid body transformation (comprising translations and rotations) that best aligns the pre- to post-event points. Perturbing the pre- and post-event point clouds independently with a synthetic right lateral inverse displacements of known magnitude along a proposed fault, ICP recovered the synthetically introduced translations. Windows with dimensions of 100-200m gave the best results for datasets with these densities. The simplified surface rupture photo interpreted and mapped in the field, delineates very well the vertical displacements patterns unveiled by ICP. The method revealed block rotations, some with clockwise and others counter clockwise direction along the simplified surface rupture. As ground truth, displacements from ICP have similar values as those measured in the field along the main rupture by Fletcher and collaborators. The vertical component was better estimated than the horizontal having the latter problems in flat areas as expected. Hybrid approaches, as simple differencing, could be taken in these areas. Outliers were removed from results. ICP detected extraction from quarries developed between the two dates of LiDAR collection and expressed as a negative vertical displacement close to the sites. To improve the accuracy of the 3D displacement field, we intend to reprocess the pre-event source survey data to reduce the systematic error introduced by the sensor. Multidisciplinary approach will be needed to make tectonic inferences from the 3D displacement field revealed by ICP, about the processes at depth expressed at surface.

    We use 142 GPS velocity estimates from the SCEC Crustal Motion Map 4 and 59 GPS velocity estimates from additional sites to model the crustal velocity field of southern California, USA, and northern Baja California, Mexico, prior to the 2010 April 4 Mw 7.2 El Mayor-Cucapah (EMC) earthquake. The EMC earthquake is the largest event to occur along the southern San Andreas fault system in nearly two decades. In the year following the EMC earthquake, the EarthScope Plate Boundary Observatory (PBO) constructed eight new continuous GPS sites in northern Baja California, Mexico. We used our velocity model, which represents the period before the EMC earthquake, to assess postseismic velocity changes at the new PBO sites. Time series from the new PBO sites, which were constructed 4-18 months following the earthquake do not exhibit obvious exponential or logarithmic decay, showing instead fairly secular trends through the period of our analysis (2010.8-2012.5). The weighted RMS misfit to secular rates, accounting for periodic site motions is typically around 1.7 mm/yr, indicating high positioning precision and fairly linear site motion. Results of our research include new fault slip rate estimates for the greater San Andreas fault system, including model faults representing the Cerro Prieto (39.0±0.1 mm/yr), Imperial (35.7±0.1 mm/yr), and southernmost San Andreas (24.7±0.1 mm/yr), generally consistent with previous geodetic studies within the region. Velocity changes at the new PBO sites associated with the EMC earthquake are in the range 1.7±0.3 to 9.2±2.6 mm/yr. The maximum rate difference is found in Mexicali Valley, close to the rupture. Rate changes decay systematically with distance from the EMC epicenter and velocity orientations exhibit a butterfly pattern as expected from a strike slip earthquake. Sites to the south and southwest of the Baja California shear zone are moving more rapidly to the northwest relative to their motions prior to the earthquake. Sites to the west of the Laguna Salada fault zone are moving more westerly. Sites to the east of the EMC rupture move more southerly than prior to the EMC earthquake. Continued monitoring of these velocity changes will allow us to differentiate between lower crustal and upper mantle relaxation processes.

    2010-12-01

    The El Mayor-Cucapah earthquake (Mw = 7.2) was the largest earthquake to occur in northeastern Baja California since February 1892, when an earthquake of slightly lower magnitude occurred at the northwestern end of the Laguna Salada fault. This event, with epicenter located ~ 40 km south of the city of Mexicali, occurred on April 4, 2010 at 15:40 local time or 22:40 UTC. Thirteen strong motion stations of a network operated by CICESE in Baja California were triggered by the main shock. Those stations are located at distances of 12 to 140 km from the epicenter. Six of them are located on sediments of the Mexicali Valley, at less than 40 km from the epicenter; the other seven stations recorded at larger distances, on granitic rocks of the peninsular ranges of Baja California. In this study, we analyze the digital accelerograms produced by the main shock and by most of the larger aftershocks. At first, the P-wave arrival times measured on the accelerograms were combined with time readings from the closer-to-the-source weak-motion stations to relocate the hypocenters. With this, we attempted to improve the hypocenter locations obtained on the basis of more regional data sets. Due to lack of station coverage to the south of the main-shock’s epicenter, this task was particularly important for those aftershocks occurring along the SE extension of the ruptured area. Our located hypocenters had smaller location errors and provide a better insight about the extent of the main-shock rupture to southeast. Concerning the strong motion data, we noted that on sediments the recorded peak ground accelerations (PGA) varied from 0.148 to 0.815 g, while on the rock sites the PGA were in the range 0.013 to 0.074 g. The largest peak acceleration recorded was observed on the vertical component of the MDO station, sited on sediments. For ground velocity and displacement, the peak values from sedimentary sites are between 14 and 61 cm/sec and 9 and 52 cm, respectively. In such instances the larger values were always observed on the horizontal components of ground motion. From these comparisons, an immediate conclusion is that peak strong motion parameters from sediment sites were, on average, up to ten times higher than those from rock sites. Finally, and in addition to a general description of the recorded ground motions, other aspects of the earthquake, like PGA attenuation with distance, spectral composition of the ground motions, nonlinearity features and preliminary estimations of the radiated seismic energy and stress drop will also be briefly addressed in our technical presentation.

    We study postseismic deformation after the Mw 7.7 earthquake in the Balochistan region of western Pakistan on 24 September 2013 and the Mw 7.2 El Mayor-Cucapah (EMC) earthquake in Baja California of northern Mexico on 4 April 2010. Pakistan InSAR measurements from the German TerraSAR-X (TSX) and Canadian RADARSAT-2 (RS2) satellites include TSX narrow stripmap beams on a descending track, RS2 wide strip modes, and TSX wide-swath ScanSAR images on an ascending track, specially acquired with interferometric alignment of ScanSAR bursts. For the EMC earthquake, InSAR includes Envisat, ALOS, and RS2 satellites and NASA/JPL UAVSAR airborne InSAR, with piece-wise time coverage. Plate Boundary Observatory acquires continuous GPS data and others collect campaign GPS. Interferograms show significant afterslip on both main ruptures in the first weeks and months, not masked by the atmospheric effects. Balochistan shallow afterslip reaches at least 10 cm in 2-4 months in the same area as the largest coseismic slip, but less near the aftershock activity. Rapid afterslip was observed primarily at the ends of the EMC mainshock rupture where the strike changes, with magnitudes up to 30 cm. Large variations of tropospheric water vapor complicate measurement of small long-wavelength deformation so we do time series analysis. We expect viscoelastic relaxation after these two strike-slip earthquakes to differ due to completely opposite tectonic settings: EMC earthquake in the Salton Trough rift and fast-moving strike-slip system, where crust and lithosphere are thin and hot with very shallow asthenosphere, and Balochistan earthquake in the shortening Makran accretional prism with much slower strike-slip deformation rates and cold and thick lithosphere of the subducting Arabian plate directly beneath it, so asthenosphere is much deeper. Studies have found rapid and large viscoelastic relaxation for the EMC quake, but we don't expect measurable relaxation in the Balochistan area in the first year, based on preliminary modeling. These very different lithospheric configurations have strong implications for transfer of stress and future earthquake risk.

    Following the 4 April 2010 El Mayor-Cucapah earthquake, 8 temporary seismometers were installed in the Yuha Desert region north of the Mexican border. During the deployment period, between 6 April and 14 June 2010, over 4,000 aftershocks, within a 20km by 14km study area in the Yuha Desert, are reported in the SCEDC catalog. We relocate the aftershocks and also determine shallow crustal anisotropy to illuminate the complex fault structure in this region. We compute the double difference hypocenter relocations using hypoDD with both manually picked P and S phase arrivals and waveform cross-correlations. We test three velocity models based on the Imperial Valley profile from the SCEC Community Velocity Model, Version 4 (CVM-S4), including the original profile and the profile with a 10% and 20% velocity reduction in Vp/Vs. We use a jackknife test in which the relocations are recomputed with one of the 13 stations removed in each test to estimate horizontal and vertical relative errors. By comparison with the LSQR errors of hypoDD, we find that scaling the LSQR errors by the jackknife/ LSQR error ratio provides a better error estimate. We find that the Imperial Valley profile with a 10% velocity reduction results in the lowest location errors. The absolute and relative relocation errors were reduced by at least an order of magnitude when compared to the original SCEDC catalog locations. We then use statistical uncertainties in the data to identify simple structures in the cloud of earthquake relocations. This modified collapsing method employs principal component analysis to identify three types of structures that a set of closely located events is most likely associated with: point, line or plane. With this method, collapsed locations provide insight to the poorly understood geologic structures in the Yuha Desert. Additionally, we measure the shallow crustal anisotropy using shear wave splitting techniques. Preliminary visual inspection of the data suggests clear split shear waves with relatively large delays. For more quantitative analysis of the data we use an automated shear wave splitting code to estimate the fast orientation and delay times for the roughly 2,900 relocated aftershocks. We will then examine the results for spatial and/or temporal variations in splitting parameters. Quantifying crack orientation and delay time parameters will allow us to infer whether the anisotropy is due to the local stress field and/or due to structure-induced anisotropy.

  13. Observations and Modeling of the Mw 7.2 2010 El Mayor-Cucapah Earthquake with Real-Time High-Rate GPS and Accelerometer Data: Implications for Earthquake Early Warning and Rapid Response (Invited)

    The Mw 7.2 April 4, 2010 El Mayor-Cucapah earthquake demonstrated convincingly the power of dense near-source, high-rate, real-time GPS networks for earthquake early warning and rapid earthquake response. With funding from NASA’s Advanced Information System Technologies (AIST) program, a robust set of 1 Hz data was collected from over 100 California Real Time Network (CRTN) GPS stations in southern California with a latency of about 0.4 seconds. These data were inverted to provide on-the-fly total displacement waveforms, which captured the propagation of the S-wave through the southern California crust at stations up to 450 km from the epicenter. By “total displacement” we mean direct measurement of both static and dynamic displacements, previously relegated separately to geodesy and seismology, respectively. While most broadband seismic stations clipped for this earthquake, including the Pinyon Flat Observatory (PFO) about 180 km from the epicenter (although accelerometers at the same sites did not), the real-time GPS stations did not saturate and continued to provide on-scale data. A special portlet was set up on the GPS Explorer data portal (http://geodemo-c.ucsd.edu/gridsphere/gridsphere) with information on our response to this event. In addition, three component 1 Hz seismograms of CRTN GPS stations for this earthquake were made available in SAC format at the Southern California Earthquake Data Center (see link below). We discuss lessons learned from this earthquake, in terms of earthquake early warning, on-the-fly optimal combination of GPS and accelerometer data, near-real-time estimation of earthquake magnitude and source parameters, and rapid static and time-dependent earthquake modeling to allow first responders and researchers to pinpoint regions of highest damage. We also discuss ways to better coordinate cross-community (Geodesy-Seismology) data dissemination challenges during large events that arise from practical considerations but also because of the fundamental differences between GPS time series derivation and seismic data recording. One of the differences is the noise on seismic recordings is usually considered to be uncorrelated between seismograms, but with high-rate GPS, it is highly correlated.

    In captive ruminants housed in small enclosures, hypertrophy of the outer hooves of the hindlimbs is often observed. We hypothesised that the underlying cause is overload attributable to an asymmetry of the digits, especially with respect to their length. To test this hypothesis, the bones of the digits of four species of artiodactyls, which included 11 wild chamois (Rupicapra rupicapra), 11 captive fallow deer (Dama dama), 11 captive bison (Bison bison) and 11 European moose (Alces alces; 9 wild, 2 captive), were radiographed post mortem and measured using a computer programme. In addition, the dimensions of the outer and inner hooves were measured directly with a caliper. The mean lengths of the epiphysis of the fourth metacarpal/metatarsal bone and the first and second phalanges of the fourth digit were greater than that of the third digit, whereas the third phalanx of the third digit had a greater mean length. The mean total length of the fourth digit of the forelimbs was greater than that of the third digit in 73-95% of specimens, depending on species. In the hindlimbs, the fourth digit was longer in 91-100% of the specimens. The hooves of the fourth digit were significantly broader than the hooves of the third digit, whereas the inner hooves of the third digits had a greater toe length than those of the fourth digit. The paired digits of artiodactyls are uneven in length, which suggests a different function during stance and weight bearing. It is conceivable that this asymmetry is the result of selection processes that favoured locomotion on soft ground. PMID:19386479

    2013-04-01

    Chemical analysis of major elements was used to investigate the characteristics of various springs and surface water in the Radovna River valley. The valley is situated in the north-western part of Slovenia. It is 17-kilometre long Alpine river flowing between karstic plateaus of Pokljuka and Mežakla confluenting with Sava Dolinka River. Wider area of the valley is built up by Triassic limestone and dolomite. Quaternary alluvial and glacial sediments occur in the bottom of the valley and on the slopes of the plateaus. Water was sampled monthly from May 2005 till March 2007 at 10 locations along the valley. Locations are divided into: 5 springs, 3 surface water locations, 1 small lake and 1 artesian borehole. On site conductivity, pH and water temperature was measured and samples for chemical analyses were collected. Groundwater, spring water and surface water are related to carbonate rocks; therefore the pH of the samples is in range between 7.1 and 8.4. In most cases pH of river water is higher than that of groundwater and spring water. Conductivity of the water varied in the interval between 188 ?S/cm and 374 ?S/cm. Results of chemical analyses show that concentration of Ca2+ exceeds that of Mg2+ in all of the samples and Ca/Mg ratio varies between 2.6 and 16.8. The concentration of Na+ is lower than Mg2+, but always higher than that of K+. Predominant anion is the HCO3- and varies between 100 mg/l and 211 mg/l. Concentration of anions Cl-, NO3- and SO42- are low and range from 0.1 mg/l to 7.47 mg/l and between 0.62 mg/l and 12 mg/l for Cl- and SO42-, respectively. NO3- is in almost all of the samples below 1 mg/l. Water data shows that waters are alkaline and the dominant facies is Ca-Mg-HCO3-. Ion concentrations fluctuate seasonally and are related to changes in discharge. In winter and early spring, when the discharge is low, the ion concentrations are higher and in late spring and summer during snowmelt, when the discharge is higher, the ion concentration are lower. Generally, ion concentrations in the water are also increasing downstream from the main spring. Chemical analyses of the water samples reflect typical karst spring dynamics and dynamics of groundwater fluctuations in the alluvium. Along the course of the river, water flow is increasing due to great amount of groundwater drainage in to the stream, therefore the chemical concentrations are increasing downstream.

    Based on recent results obtained with the Hubble Space Telescope, we present a census of genuine globular clusters in the Large Magellanic Cloud (LMC) and we examine their spatial distribution. Spectroscopic observations carried out at Complejo Astronómico El Leoncito (CASLEO, Argentina) allow us to add two new clusters (NGC 1928 and NGC 1939) to the list of genuine LMC globular clusters. We present evidence that old clusters projected on the LMC bar region may constitute a population II core, probably reminiscent of an ancient bulge, which together with a central disc could have evolved into the observed LMC bar by SMC and/or Galaxy interactions. A detailed discussion was given in MNRAS 305, 373 (1999).

  6. Geology and preliminary dating of the hominid-bearing sedimentary fill of the Sima de los Huesos Chamber, Cueva Mayor of the Sierra de Atapuerca, Burgos, Spain

    Sediments of the Sima de los Huesos vary greatly over distances of a few meters. This is typical of interior cave facies, and caused by cycles of cut and fill. Mud breccias containing human bones, grading upwards to mud containing bear bones, fill an irregular surface cut into basal marls and sands. The lack of bedding and the chaotic abundance of fragile speleothem clasts in the fossiliferous muds suggests that the deposit was originally a subterranean pond facies, and that after emplacement of the human remains, underwent vigorous post-depositional rotation and collapse and brecciation, caused by underlying bedrock dissolution and undermining. The fossiliferous deposits are capped by flowstone and guano-bearing muds which lack large-mammal fossils. U-series and radiocarbon dating indicates the capping flowstones formed from about 68 ka to about 25 ka. U-series analyses of speleothem clasts among the human fossils indicate that all are at, or close to, isotopic equilibrium (>350 ka). The distribution of U-series dates for 25 bear bones (154??66ka) and for 16 human bones (148??34 ka) is similar and rather broad. Because the human bones seem to be stratigraphically older than those of the bears, the results would indicate that most of the bones have been accumulating uranium irregularly with time. Electron spin resonance (ESR) analyses of six selected bear bones indicates dates of 189??28 ka, for which each is concordant with their corresponding U-series date (181??41 ka). Combined ESR and U-series dates for these samples yielded 200??4 ka. Such agreement is highly suggestive that uranium uptake in these bones was close to the early-uptake (EU) model, and the dates are essentially correct. Another three selected samples yielded combined ESR-U-series dates of 320??4 ka with a modeled intermediate-mode of uranium uptake. The dating results, therefore, seem to provide a firm minimum age of about 200 ka for the human entry; and suggestive evidence of entry before 320 ka. ?? 1997 Academic Press Limited.

  10. Effects of the El Mayor Cucapah April 4, 2010 earthquake and water management decisions on the Colorado River Delta tidal inundation patterns: implications for shorebirds habitat availability

    2010-12-01

    The Upper Gulf of California and Colorado River Delta (CRD) provide feeding and resting areas for migratory and resident shorebirds. Coastal and inland wetlands create a variety of habitats that support 31 shorebird species. Total shorebirds during the winter and spring migration ranges from 56,156 to 195,073. The Cienega de Santa Clara is an artificial wetland that receives saline water inflows from the United States, and the southeastern portion (the Santa Clara Slough) receives a mix of brackish effluent from the Cienega and occasional tidal inundation during extreme high tides. This transitional wetland between the sea and the land is one of the main shorebird aggregation areas within the CRD, supporting 29 to 75% of the individuals using the entire Upper Gulf and CRD. The Cienega de Santa Clara is currently experiencing a 30% reduction in inflows due to operation of the Yuma Desalting Plant in the United States. The 2010 Baja California earthquake caused changes in the tidal water inflows patterns in the delta. Time sequence Landsat images and aerial observations showed that a new wetland area has been created since tidal water inflows are now diverted from the southeast edge of the Cienega to the southwest areas due to subsidence effects. The aim of this study was to document the changes in the shorebird inland habitats to predict shifts in shorebird habitat use by using aerial and ground surveys before and after the earthquake. Preliminary results shows that some of the areas with a high density of shorebird use has dried out mainly as a consequence of the reduction in water inflows to the Cienega from the United States and diversion of water from the Santa Clara Slough to the new tidal basins northwest of the Slough. Aerial surveys suggest that shorebirds were not yet visiting the new wetland area during the past spring migration and were more abundant over the San Felipe coastline and Montague Island. Shorebird habitat has been influenced by a combination of water management decisions, tidal dynamics, and landform changes due to the recent seismic event in the CRD. Further monitoring is needed to determine if shorebirds will relocate to new habitat or diminish in numbers in this important ecosystem.

  13. Coseismic Deformations Associated with the M=7.2, April 04, 2010, El Mayor-Cucapah Earthquake, Observed from Leveling Survey, Geotechnical Instruments and Water Level Changes in the Mexicali Valley

    Glowacka, E.; Robles, B.; Vázquez, R.; Sarychikhina, O.; Suárez-Vidal, F.; Ramirez, J.; Nava Pichardo, F. A.; Farfan, F.; Diaz de Cossio, G.

    2010-12-01

    A first order, second class leveling survey in the Mexicali Valley had been just finished in February 2010, for a project carried out by CICESE (Center for Scientific Research and Higher Education of Ensenada), IMTA (Mexican Institute of Water Technology) and CONAGUA (National Water Comission). Immediately after the M=7.2 earthquake the survey was repeated along 240 km of the profiles in the area of the Cerro Prieto pull-apart basin. The leveling started at the LN00 GPS monument in La Puerta. Overall, an uplift of about 30 cm towards the NE, along the 38 km line, in direction SW-NE is observed with larger gradient to the South of the area. Three subsidence bowls differ from this general pattern. One, south from Ejido Saltillo, with the relative subsidence of 19 cm (considering the displacement at LN00 as zero subsidence), probably reflects subsidence of the Saltillo-Guerrero graben; the second, with a subsidence of 23 cm, is situated south from Ejido Nuevo Leon and can be related to the subsidence triggered by the earthquake in the production area of Cerro Prieto IV. For the third one, with relative depth of 36 cm, situated close to Zacamoto, the southeastern limit cannot be determined, so only a comparison with other methods can explain the origin of this anomaly. All the subsidence bowls are associated with liquefaction observed in the area, with more liquefaction observed close to Zacamoto. Since 1996, CICESE has been operating a network of geotechnical instruments (REDECVAM) for continuous recording of deformation related to tectonic (seismic and interseismic) phenomena, as well as anthropogenic deformation caused by the deep fluid extraction at the Cerro Prieto Geothermal Field. The instruments are installed along the faults which limit the Cerro Prieto pull-apart basin at a distance from 8 to 15 km from the epicenter. Coseismic step-like groundwater level changes ranging from 0.4 to 5.0 meters were recorded at 4 wells in the Cerro Prieto Pull apart-basin equivalent to coseismic volumetric strain field, in the depth of the piezometers, of the order of 10-6 - 10-5. Instruments installed along the “continuation of the Cerro Prieto” fault recorded vertical slip of 6 cm, and inclination changes of ~700 microradians, with 10 cm vertical slip measured with a ruler at the surface, Instruments installed on the Saltillo fault recorded up to 3000 microradians change, and vertical and horizontal displacements, measured manually, were of the order of centimeters. The Morelia fault had about 30 cm vertical displacement measured manually. The displacement velocities observed by the instruments are much larger than the aseismic slip velocities or triggered slip velocities observed previously in this area. A comparison between leveling results and geotechnical observations suggests that the magnitude of deformation observed by the instruments is confirmed by the leveling only in the Saltillo-Guerrero graben, thus suggesting that the observed slip triggered on the Morelia and Cerro Prieto faults is shallow.

    Vaginosis bacteriana (VB) es una infección caracterizada por el cambio en la microflora de la vagina, asociándose a resultados adversos del embarazo y a la adquisición de infecciones de transmisión sexual (ITS), incluyendo el VIH. En este estudio se buscó la asociación entre el uso de duchas vaginales y otros factores de riesgos con VB. Se usó un diseño observacional descriptivo transversal prospectivo, en 1,252 mujeres que asistieron al servicio de planificación familiar de tres hospitales nacionales (Dos de Mayo, Arzobispo Loayza, San Bartolomé) y el Instituto Materno Perinatal, durante el año 1997. Se utilizó un cuestionario estructurado donde se registraron variables socio demográficas y características del estilo de vida de las participantes. VB fue diagnosticada mediante el puntaje de Nugent. Se empleó análisis de regresión logística para calcular odds ratio (OR) e intervalos de confianza al 95%. La edad promedio de las participantes fue 25.1 ± 4,7 años, el 23.4% tenían más de 11 años de educación. La prevalencía de VB fue 20,1%. Las mujeres que practicaban duchas vaginales tuvieron 2.28 veces (OR = 2.28, IC 95% [1.0–5.0]) mayor probabilidad de tener VB comparado con aquellas que no lo practicaban. Tener dos o más parejas sexuales estuvo asociado con 2.0 veces (OR =2.0, IC 95% [1.2–3.5]) mayor probabilidad de adquirir VB comparado con aquellas que habían tenido solo una pareja sexual. Las participantes que iniciaron una relación sexual a una edad temprana tuvieron 1.4 veces (OR=1.4, IC 95% [1.0 –1.9]) mayor probabilidad de adquirir VB. El uso de duchas vaginales es un factor de riesgo de VB. Los programas destinados a la salud de la mujer deben abordar las repercusiones perjudiciales para la salud asociados con las duchas vaginales. PMID:21132048

A partir de la datación por 210Pb de dos testigos de sedimentos (GeoB 13813-4 y BAR1) se reconstruyó la geocronología del ambiente, y se relacionó con datos de las forzantes climáticas Pacific Decadal Oscillation, El Niño/La Niña Southern Oscillation, Atlantic Multidecadal Oscillation, y las anomalías hidrológicas de los ríos Paraná y Uruguay. Los valores más positivos y estables del Southern Oscillation Index, los cuales corresponden a fases La Niña, se observan en el periodo correspondiente entre 1910-1970, respecto al resto de la serie, donde se aprecia una mayor variabilidad y una tendencia hacia valores más negativos (eventos El Niño). Se hicieron dendrogramas (clustering) jerárquicos para ambos testigos. Para el testigo GeoB 13813-4, se utilizó la relación Ca/Ti y la granulometría, mientras que para BAR1 se recurrió a variables granulométricas y la tasa de sedimentación. El mayor aporte continental hacia la región de la plataforma adyacente al Río de la Plata registrado a partir del año 1970, podría ser el factor principal de los agrupamientos observados en los clusters para ambos testigos. Las agrupaciones mostraron una diferenciación en la década de 1970, lo que estaría asociado al aumento de los caudales de los ríos Paraná y Uruguay, durante las últimas tres décadas del siglo XX. Por otra parte se observa que la granulometría del testigo BAR1 presentó un mayor tamaño de grano y más variabilidad que en el caso del testigo GeoB 13813-4. También se determinó una mayor acumulación de sedimentos a través del tiempo en el cinturón de barro del Río de la Plata (plataforma continental adyacente), comparado con aquel registrado en la Barra del Indio (límite entre zona intermedia y externa del estuario). Estas diferencias podrían estar relacionadas con la influencia del Río de la Plata, el cual genera un ambiente altamente dinámico sobre la Barra del Indio y un ambiente más estable sobre el cinturón de barro en la plataforma continental.

    Se reportan observaciones fotográficas del cometa Halley, obtenidas con los telescopios Schmidt de 1-m del CIDA, y de 35 cms de la ULA. Se hicieron exposiciones desde 2 segundos a 30 minutos y se utilizaron emulsiones IIa-O, 103a-F, y 103a-D, guladas manualmente 0 automaticámente. Las imágenes fueron digitalizadas con el microdensitómetro PDS, y procesadas con el sistema HACIENDA del CCIBM. Se experimentó con la Transformada de Fourier en dos dimensiones, y con la aplicación de filtros de paso alto y bajo. Se encontró que el metodo de "autocorrelación" es el mejor para separar "la vegetación" de "la montaña". Se aplicaron diversas técnicas a fin de cubrir ambos extremos: a) enfatizar detalles débiles en la cola, y b) penetrar en las regiones más intensas de la coma. Se lograron ambos objetivos. Detalles en la cola permitieron determinar velocidades de propagación de unos 50 a 90 kms/ seg. Se pudieron detectar no menos de tres perturbaciones en "Y", y una en 5? Co de Cisne). Se cree que las primeras están asociadas a eventos de desconexión. Se puede separar la cola de gas de la de polvo. Las fotos de color permiten enfatizar diferentes regiones espectrales con mayor claridad aún. El "balance" del color puede ser hecho con la computadora.

    Uno de los aspectos importantes relativos a la geodinámica del interior terrestre es la correlación entre los eventos de cambio en la velocidad de rotación terrestre y los determinados en los elementos del campo geomagnético por ejemplo, la Declinación Magnética, o los coeficientes de los modelos matemáticos de representación global de dicho campo. En este trabajo se presentan los resultados de las características espectrales de los cambios observados en la longitud del día (ldd), y su relación con la estructura espectral de las coeficientes de los modelos matemáticos de campo denominados Campo Internacional Geomagnético de Referencia (CIGR). El intervalo estudiado comprende los últimos 100 años. Los resultados muestran una correlación en las bandas de 60 y 30 años, con posibles períodos mucho mayores que no son posibles determinar a partir de los modelos de CIRG. Se efectúa una simulación a partir de los resultados obtenidos por la aplicación del método de máxima entropía con longitudes del filtro predictor de error comprendida entre el 10% y el 95% de la longitud de la serie analizada. Se observan procesos sicrónicos y asincrónicos que, en muy largos intervalos de tiempos, podrían suponerse como caóticos.

    Resumen El rastreo de cáncer colorrectal (CCR) cuenta con fuertes evidencias en su favor. Datos preliminares indican que a pesar de ello no se lleva a cabo con la frecuencia adecuada. Se intenta aquí determinar, dentro de un Sistema de Salud que cuenta con los recursos necesarios, los elementos que facilitan o generan barreras para concretar esta práctica preventiva, cuántos individuos lo ponen en práctica y qué predice esta conducta. Se realizó una encuesta telefónica a los afiliados de una Obra Social de empleados de la Universidad de Buenos Aires, de los que 132 completaron el cuestionario (tasa de respuesta 70%). Los elementos considerados facilitadores del rastreo obtuvieron respuestas afirmativas en el 64 a 97%, mientras que los que definían barreras un 11 a 27%. En este último grupo, una categoría diferenciada la constituía el miedo a los efectos adversos: 39%, y el sentimiento de vergüenza relacionado con los procedimientos: 30%. Un 33% de los encuestados tenían hecho un método de rastreo, mayoritariamente de sangre oculta (27), sigmoideoscopía (11) y colonoscopía (20). Una mayoría afirmó que “se haría el procedimiento si el médico se lo recomendara” (95%), o “no se lo haría excepto que su médico se lo aconseje” (87%). Contestar afirmativamente que “los médicos hacen lo mejor para los pacientes” se asoció con haberse hecho un método de rastreo de CCR, OR 1.55 (IC 95%: 1.02-2.37) p: 0.04. El grupo de individuos estudiado parece bien predispuesto para el rastreo del CCR, la recomendación médica sería aquí un determinante prominente para ponerlo en práctica. PMID:19414294

    We occasionally include projects in our learner-centered introductory astronomy college course to enable non-science major students explore some astronomical concepts in more detail than otherwise. Such projects also highlight ongoing or upcoming astronomical events. We hope that students will feel more interested in astronomy through projects tied to astronomical events. In Spring 2012, we offered short essays focused on eclipses, transits and occultations to promote the rare transit of Venus that occurred on June 5th, 2012. We asked students to write two short essays from three that were offered. The essays contained descriptive and conceptual parts. They were meant to serve as teaching tools. 62% of 106 essays from 55 students earned A, B or C grades. 21% of 47 feedback survey respondents felt the essays increased their interest in astronomy. 49% of respondents felt that the essays were not educationally beneficial and should not be offered again. The most common written response to our survey indicated that students need more guidance and better preparation in writing successful essays. Since students found the conceptual parts of the essays difficult, in the future we will provide relevant activities prior to essay deadlines to help students create successful essays. Ocasionalmente, incluimos proyectos en nuestro curso de introducción a la astronomía universitario centrado en el alumno para permitir que los estudiantes de carreras no científicas exploren algunos conceptos astronómicos en más detalle que lo habitual. Estos proyectos también ponen en relevancia eventos astronómicos en curso o futuros. Esperamos que los estudiantes se sientan más interesados en la astronomía a través de proyectos vinculados a eventos astronómicos. En el período de primavera de 2012 (EUA), propusimos breves ensayos centrados en los eclipses, tránsitos y ocultaciones para promover el raro tránsito de Venus que se produjo el 5 de junio de 2012. Le pedimos a los estudiantes que escribieran dos ensayos cortos de tres que se proponían. Los ensayos contenían partes descriptivas y conceptuales. Los mismos estaban destinados a servir como herramientas de enseñanza. 62% de los 106 ensayos de 55 estudiantes obtuvo grados A, B o C. 21% de los 47 encuestados que respondieron al cuestionario posterior consideró que los ensayos aumentaron su interés por la astronomía. 49% de los encuestados consideró que los ensayos no eran educacionalmente útiles y que no deben ser propuestos de nuevo. Las respuestas escritas más comunes a nuestra encuesta indicaran que los estudiantes necesitan más orientación y una mejor preparación en la redacción de ensayos exitosos. Dado que los estudiantes encontraron las piezas conceptuales de los ensayos difíciles, en el futuro vamos a ofrecer actividades pertinentes antes de los plazos de redacción para ayudar a los estudiantes a crear ensayos de mayor calidad. Nós ocasionalmente incluímos projetos em nosso curso universitário introdutório centrado no aluno para permitir aos estudantes que pertencem às carreiras não científicas explorar alguns conceitos astronômicos em mais detalhes do que o normal. Tais projetos também enfatizam eventos astronômicos em curso ou futuros. Esperamos que os alunos se sintam mais interessados na astronomia através de projetos ligados a eventos astronômicos. No termo de Primavera de 2012 (EUA), propomos ensaios curtos focados em eclipses, trânsitos e ocultações para promover o raro trânsito de Vênus que ocorreu no dia 5 de junho de 2012. Pedimos aos alunos que escrevessem dois ensaios curtos dentre três que foram propostos. Os ensaios continham partes descritivas e conceituais. Eles foram feitos para servir como ferramentas de ensino. 62% de 106 ensaios de 55 alunos ganhou graus A, B ou C. 21% dos 47 entrevistados que responderam ao levantamento posterior sentiu que os ensaios aumentaram seu interesse na astronomia. 49% dos inquiridos consideraram que os ensaios não eram benéficos para a educação e que não devem ser propostos novamente. As respostas escritas mais comuns da nossa pesquisa indicaram que os alunos precisam de mais orientação e melhor preparação para escrever ensaios bem sucedidos. Como os alunos consideraram difíceis os aspectos conceituais dos ensaios, no futuro iremos fornecer atividades relevantes antes dos ensaios para ajudar os alunos a escrevê-los com sucesso.

  8. Improving mating performance of mass-reared sterile Mediterranean fruit flies (Diptera: Tephritidae) through changes in adult holding conditions: demography and mating competitiveness

    Mass rearing conditions affect the mating behavior of Mediterranean fruit flies (medflies) Ceratitis capitata (Wiedemann). We evaluated the effect of slight changes in the adult holding conditions of adult flies maintained for egg production on their mating performance. Colonization was initiated from wild flies collected as larvae from infested coffee berries (Coffea arabica L.). When pupae were close to adult emergence, they were randomly divided into 3 groups and the emerging adults were reared under the following conditions: (1) Metapa System (MS, control), consisting of 70 x 45 x 15 cm aluminum frame, mesh covered cages, with a density of 2,200 flies per cage and a 1:1 initial sex ratio; (2) Insert System (IS), with the same type of cage, and the same fly density and sex ratio as in the MS treatment, but containing twelve Plexiglas pieces (23 x 8.5 cm) to provide additional horizontal surface areas inside the cage; and (3) Sex-ratio System (SS), same as IS, but in this case the initial male: female ratio was 4:1. Three d later, newly emerged females were introduced, so the ratio became 3:1 and on the 6th d another group of newly emerged females was added to provide a 2:1 final sex ratio, at which the final density reached 1,675 flies per cage. The eggs collected from each of the 3 treatments were reared independently following standard procedures and the adults were held under the same experimental conditions. This process was repeated for over 10 to 13 generations (1 year). The experiment was repeated 3 times in 3 consecutive years, starting each replicate with a new collection of wild flies. Life tables were constructed for each treatment at the parental, 3rd, 6th, and 9th generations. Standard quality control parameters (pupation at 24 h, pupal weight, adult emergence, and flight ability), were estimated for each treatment every third generation in the third year. For the last generation each year, mating competitiveness was evaluated in field cage tests with wild flies. As colonization progressed, life expectancy and fecundity rates increased in the 3 rearing systems. There was no significant difference in standard quality control parameters among the 3 rearing systems. Wild males always achieved more matings than any of the mass reared males. Mating competitiveness of males from the IS, although surprisingly not from the SS, was significantly greater than that of males from the MS. Our results indicate that these slight changes in the adult holding conditions can significantly reduce the harmful effects of mass rearing on the mating performance of sterile flies. (author) [Spanish] Se ha demostrado que las condiciones de cria masiva afectan el comportamiento de apareamiento de la mosca del Mediterraneo Ceratitis capitata (Wiedemann). Nosotros evaluamos el efecto de ligeros cambios en las condiciones en las que los adultos son mantenidos para la produccion de huevos, en el desempeno de apareamiento de las moscas esteriles. La colonizacion se inicio con moscas silvestres colectadas como larvas en cerezas de cafe (Coffea arabica L.) infestadas. Cuando las pupas estuvieron cerca de la emergencia de los adultos, se dividieron en tres grupos al azar y los adultos recien emergidos fueron criados en las siguientes condiciones: (1) Sistema Metapa (MS, testigo), consistente en jaulas con marco de aluminio de 70 x 45 x 15 cm, cubiertas con malla, con una densidad de 2,200 moscas por jaula y una relacion de sexos inicial de 1:1; (2); Sistema Insertos (IS), con el mismo tipo de jaula, densidad de moscas, y relacion de sexos que en el MS, pero conteniendo 12 piezas de plexiglas (23 x 8.5 cm) para proporcionar superficie horizontal al interior de la jaula; y (3) Sistema de Relacion de Sexos (SS), igual que el IS, pero en este caso la relacion inicial macho: hembra fue de 4:1, tres dias despues se introdujeron hembras recien emergidas para tener una relacion de 3:1 y en el 6 dia se anadio otro grupo de hembras para tener una relacion final de sexos de 2:1, que equivale a una densidad final de 1,675 moscas por jaula. Los huevos colectados de cada tratamiento fueron criados independientemente siguiendo los procedimientos estandares y los adultos fueron mantenidos en las mismas condiciones experimentales. Esto se repitio por 10 a 13 generaciones (un ano). El experimento se repitio en tres ocasiones en anos consecutivos, iniciando cada repeticion con una nueva colecta de moscas silvestres. Se construyeron tablas de vida de cada tratamiento en las generaciones parental, 3 a, 6 a y 9 a . Se estimaron los parametros estandares de calidad (pupacion a las 24 h, peso de pupa, emergencia de adultos y habilidad de vuelo) para cada tratamiento, cada tercera generacion en el tercer ano. En la ultima generacion de cada ano, se evaluo la competitividad sexual en pruebas en jaulas de campo con moscas silvestres. Conforme avanzo la colonizacion, se encontro que la esperanza de vida y las tasas de fecundidad se incrementaron en los tres sistemas de cria. No hubo diferencia significativa en los parametros estandar de control de calidad entre los tres sistemas. Los machos silvestres siempre lograron mas apareamientos que los machos procedentes de cada sistema de cria masiva. La competitividad de los machos del sistema IS fue significativamente mayor que la de los machos del sistema MS. Nuestros resultados indican que estas ligeras modificaciones en las condiciones de la colonia de adultos reducen los efectos adversos de la cria masiva sobre el desempeno de apareamiento de los machos esteriles.

  1. Land subsidence caused by groundwater exploitation in Suzhou City, China

    NASA Astrophysics Data System (ADS)

    Chen, Chongxi; Pei, Shunping; Jiao, Jiu Jimmy

    2002-09-01

    Suzhou City, located at the lower reaches of the Yangtze River in southeastern Jiangsu Province, is one of the few cities in China which suffer from severe ground settlement. A research project was carried out to investigate this problem. Geological and hydrogeological studies show that there is a multi-layered aquifer system with three distinct, soft mud layers of marine and lagoonal origins. An examination of historical records of groundwater extraction, water levels, and ground settlement shows that the ground subsidence is associated with the continuously increasing groundwater extraction in the deep, confined aquifer. It is believed that the consolidation of the soft mud layers, especially the third layer which is thick and close to the main pumped aquifer, contributes to the ground settlement. A three-dimensional finite difference numerical model representing the multi-layered aquifer system was developed to study the ground settlement in response to groundwater extraction. By calibrating the model with both the measured groundwater level and ground settlement, the aquifer parameters were estimated. The model outputs fit reasonably well with the observed results, which indicates that the numerical model can reproduce the dynamic processes of both groundwater flow and soil consolidation. The hydraulic conductivity of the third mud layer near the center of the ground settlement has been reduced by over 30% in the last 14 years. The gradual deterioration in the hydraulic conductivity of the mud may have significant adverse effect on the sustainable groundwater resource of the deep confined aquifer, since the recharge from the shallow aquifers through the mud layer is the only source of water to the deep aquifer. An analysis of the spatial distributions of groundwater drawdown and ground settlement shows that the area with maximum drawdown is not necessarily the area with maximum ground settlement due to the occurrence of the soft mud layer. A simple reallocation in pumping rates on the basis of the spatial distribution of the thick mud layer could significantly reduce the ground settlement. Résumé. La ville de Suzhou, située dans la basse vallée du fleuve Yangtsé dans le sud-est de la province de Jiangsu, est l'une des rares villes de Chine qui souffrent cruellement de tassements du sol. Un projet de recherche a été mené pour étudier ce problème. Des études géologiques et hydrogéologiques montrent qu'il existe un système aquifère multicouche constitué de trois niveaux distincts de limons non consolidés d'origine marine et lagunaire. Un examen des historiques des prélèvements d'eau souterraine, des niveaux de nappe et des tassements de sol montrent que la subsidence du sol est associée à des prélèvements continuellement croissants d'eau souterraine dans l'aquifère captif profond. On pense que le compactage des couches limoneuses non consolidées, en particulier de la troisième couche qui est épaisse et proche du principal aquifère pompé, contribue aux tassements du sol. Un modèle numérique aux différences finies en trois dimensions, représentant l'aquifère multicouche, a été réalisé pour étudier les tassements du sol en réponse aux prélèvements d'eau souterraine. Les paramètres de l'aquifère ont été estimés par calibration du modèle au moyen à la fois des niveaux piézométriques et des tassements du sol. Les résultats de la simulation s'ajustent convenablement aux résultats observés, ce qui indique que le modèle numérique peut reproduire les processus dynamiques aussi bien des écoulements souterrains que de compactage du sol. La conductivité hydraulique de la troisième couche de limon non consolidé au voisinage du centre du tassement de sol a été réduit de plus de 30% au cours des 14 dernières années. La dégradation progressive de la conductivité hydraulique du limon peut avoir un effet significatif néfaste sur la pérennité de la ressource en eau souterraine dans l'aquifère captif profond, puisque la recharge à partir des aquifères superficiels au travers de la couche de limon est la seule alimentation de l'aquifère profond. Une analyse des distributions spatiales de l'abaissement du niveau piézométrique et des tassements du sol montre que la région soumise à l'abaissement maximal de piézométrie n'est pas nécessairement celle des tassements maximaux du sol liés à la présence de la couche de limon non consolidé. Une simple révision des débits de pompage basée sur la distribution spatiale de la couche de limon épaisse peut réduire significativement les tassements du sol. Resumen. La ciudad de Suzhou, situada en el tramo inferior del Río Yangtze, al sudeste de la provincia de Jiangsu, es una de las pocas ciudades chinas que padece problemas serios de subsidencia. Esto ha motivado la realización de un proyecto de investigación en la zona. Estudios geológicos e hidrogeológicos apuntan a un modelo de acuífero multicapa, con tres niveles distintos de lodos blandos de orígenes marino y lacustre. Examinando los registros históricos de extracciones de agua subterránea, así como de nivel piezométrico y de subsidencia, se observa que ésta se halla asociada al bombeo cada vez mayor del acuífero confinado profundo. La hipótesis es que las capas de lodos blandos se van consolidando, si bien la que más contribuye a ello es la tercera, potente y próxima al acuífero más explotado. Se ha realizado un modelo numérico tridimensional en diferencias finitas que representa el sistema acuífero multicapa, con lo que se puede estudiar el efecto de la extracción de agua subterránea en la subsidencia. Calibrando el modelo con niveles piezométricos medidos y con datos de subsidencia, se ha podido estimar los parámetros del acuífero. Los resultados del modelo ajustan de forma razonable con los datos medidos, por lo que el modelo numérico es capaz de reproducir los procesos dinámicos de flujo de aguas subterráneas y consolidación del terreno. La conductividad hidráulica de la tercera capa de lodo cerca del centro de asentamiento se ha reducido en más del 30% durante los últimos 14 años. El deterioro gradual de la conductividad hidráulica del lodo puede tener efectos adversos notables en la sustentabilidad de los recursos de agua subterránea del acuífero confinado profundo, ya que se recarga exclusivamente de acuíferos más someros a través de la capa de lodo. El análisis de la distribución espacial de descenso del nivel piezométrico y de subsidencia muestra que el área de extracción máxima no coincide necesariamente con la de máxima subsidencia, debido a la existencia de la capa de lodos blandos. Una mera redistribución de los caudales de bombeo en función de las propiedades espaciales de la gruesa capa de lodos podría reducir drásticamente los problemas de subsidencia.

  2. En la búsqueda de características en eyecciones coronales de masa que discriminen entre dos paradigmas físicos en modelos de ECMs

    NASA Astrophysics Data System (ADS)

    Paissan, G.; Stenborg, G.; Rovira, M.

    Se conocen tres diferentes fenómenos de gran escala que ocurren en la atmósfera solar, denominados eyecciones coronales de masa (ECMs), protuberancias eruptivas y grandes fulguraciones de dos bandas. Estos fenómenos están estrechamente relacionados y podrían ser distintas manifestaciones de un único proceso físico. Las ECMs son definidas como eyecciones de gran escala de masa y flujo magnético desde la baja corona al espacio interplanetario. Desde su descubrimiento en los '70, muchos modelos han sido propuestos para explicar su origen y evolución. La explicación física de las ECMs es un tema de debate intenso. No obstante, los modelos pueden sintetizarse en dos grandes grupos: 1) los modelos de inyección de flujo y 2) los modelos de almacenamiento y liberación. En este trabajo, se presentan los estudios realizados con una serie de eventos observados con el coronógrafo MICA (Mirror Coronograph for Argentina), el telescopio en H-alfa HASTA (H-alpha Solar Telescope for Argentina) y los coronógrafos C2 y C3 de la sonda SOHO (Solar and Heliospheric Observatory). Los eventos que pudieron ser identificados como ECMs son contrastados dentro del esquema de los dos paradigmas teóricos propuestos.

  3. Comparison of brain mechanisms underlying the processing of Chinese characters and pseudo-characters: an event-related potential study.

    Most Chinese characters are composed of a semantic radical on the left and a phonetic radical on the right. The semantic radical provides the semantic information; the phonetic radical provides information concerning the pronunciation of the whole character. The pseudo-characters in the study consisted of different sub-lexical parts of real Chinese characters and consequently they also had the semantic radical and the phonetic radical. But they were not readable and had no actual meaning. In order to investigate the spatiotemporal cortical activation patterns underlying the orthographic, phonological and semantic processing of Chinese characters, we used event-related brain potentials (ERPs) to explore the processing of Chinese characters and pseudo-characters when 14 healthy Chinese college students viewed the characters passively. Results showed that both Chinese characters and pseudo-characters elicited an evident negative potential peaking around 120 ms (N120), which appeared to reflect initial orthographic distinction and evaluation. Then, Chinese pseudo-characters elicited a more positive ERP deflection (P220) than did Chinese characters 200-250 ms after onset of the stimuli. It was similar to the recognition potential (RP) and might reflect the integration processes of phonological and semantic processing on the basis of early orthographic information. Dipole source analysis of the difference wave (pseudo-characters minus characters) indicated that a generator localized in the left temporal-occipital junction contributed to this effect, which was possibly related to phonological and perceptual-semantic information integration. Between 350-450 ms, a greater negativity (N360) in pseudo-characters as compared to characters was found over midline fronto-central scalp regions. Dipole analysis localized the generator of N360 in the right parahippocampal cortex. Therefore, the N360 might be an N400 component and reflect the higher-level semantic activation on the basis of orthographic, phonological and perceptual-semantic processing. La plupart des caractères chinois sont composés d'un radical sémantique à gauche et d'un radical phonétique à droite. Le radical sémantique peut fournir de l'information sémantique et le radical phonétique peut fournir de l'information concernant la prononciation du caractère entier. Les pseudo-caractères consistaient en différentes parties sous-lexicales des caractères chinois réels et, conséquemment, ils avaient aussi un radical sémantique et un radical phonétique. Mais ils ne pouvaient pas être lisibles et ils n'ont actuellement aucun sens. Afin d'étudier les patrons d'activation spatiotemporels corticaux sous-jacents aux traitements orthographique, phonologique et sémantique des caractères chinois, nous avons utilisé des Potentiels cérébraux reliés aux événements (PRE) pour explorer le traitement des caractères et des pseudo-caractères chinois auprès de 14 collégiens chinois visionnant les caractères passivement. Les résultats ont montré qu'à la fois les caractères et les pseudo-caractères chinois provoquaient un potentiel négatif évident atteignant un sommet autour de 120 ms (N120), ce qui apparaissait refléter la distinction et l'évaluation orthographiques initiales. Puis, les pseudo-caractères ont provoqué une déviation PRE plus positive (P220) que les caractères chinois entre 200 et 250 ms après l'apparition des stimuli. Ceci était similaire au PR (Potentiel de reconnaissance) et pouvait refléter les processus d'intégration des traitements phonologique et sémantique sur la base de l'information orthographique initiale. L'analyse dipôle de source de la différence de courbe (pseudo-caractères moins caractères) a indiqué qu'un générateur localisé dans la jonction temporo-occipitale gauche contribuait à cet effet, ce qui était possiblement relié à l'intégration de l'information phonologique et perceptuelle-sémantique. Entre 350 et 450 ms, une plus grande négativité (N360) fut observée pour les pseudo-caractères comparativement aux caractères des régions du scalp au-dessus des régions médianes fronto-centrales. L'analyse dipôle a localisé le générateur de N360 dans le cortex para-hippocampique droit. Ainsi, le N360 pourrait être une composante N400 et refléter une activation sémantique de haut niveau sur la base des traitements orthographique, phonologique et perceptuel-sémantique. La mayoría de los caracteres chinos están compuestos por un radical semántico a la izquierda y un radical fonético a la derecha. El radical semántico puede proporcionar información semántica y el radical fonético puede proporcionar información relacionada con la pronunciación del carácter entero. Los pseudo-caracteres consistieron en diferentes partes sub-léxicas de los caracteres reales chinos y como consecuencia, también tenían radicales semánticos y fonéticos. Pero éstos no se podían leer y tampoco tenían un significado real. Para investigar los patrones de la activación cortical espaciotemporal subyacentes de los procesamientos ortográfico, fonológico y semántico de los caracteres chinos, utilizamos potencial relacionado con eventos (ERPs) para explorar el procesamiento de caracteres chinos y pseudo-caracteres mientras que 14 sanos estudiantes chinos veían los caracteres de forma pasiva. Los resultados demostraron que ambos, caracteres y pseudo-caracteres chinos evocaban potenciales negativos con picos alrededor de los 120 ms (N120), lo cual parece reflejar distinción inicial ortográfica y evaluación. Además, los pseudo-caracteres chinos provocaban una desviación ERP más positiva (P220) en comparación con los caracteres chinos entre 200-250 ms después de la aparición de los estímulos. Esto fue parecido a RP (potenciales de reconocimiento) y puede reflejar un proceso de integración del procesamiento fonológico y semántico basado en la información ortográfica temprana. Un análisis dipolo de la fuente de la onda de diferencia (pseudo-caracteres menos caracteres) indicó que un generador localizado en el cruce temporal-occipital izquierdo contribuyó a este efecto, lo cual probablemente tuvo relación con la integración de la información fonológica y perceptivo-semántica. Se encontró mayor negatividad (N360) entre 350-450 ms, en pseudo-caracteres en comparación con los caracteres situada sobre las regiones de la línea media fronto-central craneal. Un análisis dipolo localizo un generador de N360 en el cortex parahipocampal derecho. Por tanto, el N360 podría ser un componente de N400 reflejando una activación semántica de más alto nivel basado en el procesamiento ortográfico, fonológico y perceptivo-semántico. PMID:22043890

    Background: Studies have demonstrated the diagnostic accuracy and prognostic value of physical stress echocardiography in coronary artery disease. However, the prediction of mortality and major cardiac events in patients with exercise test positive for myocardial ischemia is limited. Objective: To evaluate the effectiveness of physical stress echocardiography in the prediction of mortality and major cardiac events in patients with exercise test positive for myocardial ischemia. Methods: This is a retrospective cohort in which 866 consecutive patients with exercise test positive for myocardial ischemia, and who underwent physical stress echocardiography were studied. Patients were divided into two groups: with physical stress echocardiography negative (G1) or positive (G2) for myocardial ischemia. The endpoints analyzed were all-cause mortality and major cardiac events, defined as cardiac death and non-fatal acute myocardial infarction. Results: G2 comprised 205 patients (23.7%). During the mean 85.6 ± 15.0-month follow-up, there were 26 deaths, of which six were cardiac deaths, and 25 non-fatal myocardial infarction cases. The independent predictors of mortality were: age, diabetes mellitus, and positive physical stress echocardiography (hazard ratio: 2.69; 95% confidence interval: 1.20 - 6.01; p = 0.016). The independent predictors of major cardiac events were: age, previous coronary artery disease, positive physical stress echocardiography (hazard ratio: 2.75; 95% confidence interval: 1.15 - 6.53; p = 0.022) and absence of a 10% increase in ejection fraction. All-cause mortality and the incidence of major cardiac events were significantly higher in G2 (p < 0. 001 and p = 0.001, respectively). Conclusion: Physical stress echocardiography provides additional prognostic information in patients with exercise test positive for myocardial ischemia.Fundamento: Estudos têm demonstrado a acurácia diagnóstica e o valor prognóstico da ecocardiografia com estresse físico na doença arterial coronária, mas a predição de mortalidade e de eventos cardíacos maiores, em pacientes com teste ergométrico positivo para isquemia miocárdica, é limitada. Objetivo: Avaliar a predição de mortalidade e de eventos cardíacos maiores pela ecocardiografia com estresse físico em pacientes com teste ergométrico positivo para isquemia miocárdica. Métodos: Trata-se de uma coorte retrospectiva em que foram estudados 866 pacientes consecutivos, com teste ergométrico positivo para isquemia miocárdica, submetidos à ecocardiografia com estresse físico. Os pacientes foram divididos em dois grupos: ecocardiografia com estresse físico negativa (G1) ou positiva (G2) para isquemia miocárdica. Os desfechos avaliados foram mortalidade por qualquer causa e eventos cardíacos maiores, definidos como óbito cardíaco e infarto agudo do miocárdio não fatal. Resultados: O G2 constituiu-se de 205 (23,7%) pacientes. Durante o seguimento médio de 85,6 ± 15,0 meses, ocorreram 26 óbitos, sendo seis por causa cardíaca, e 25 casos de infarto agudo do miocárdio não fatais. Os preditores independentes de mortalidade foram idade, diabetes melito e a ecocardiografia com estresse físico + (hazard ratio: 2,69; intervalo de confiança de 95%: 1,20 - 6,01; p = 0,016), com os seguintes eventos cardíacos maiores: idade, doença arterial coronária prévia, ecocardiografia com estresse físico + (hazard ratio: 2,75; intervalo de confiança de 95%: 1,15 - 6,53; p = 0,022) e ausência do incremento de 10% na fração de ejeção. A mortalidade por qualquer causa e os eventos cardíacos maiores foram significativamente superiores no G2 (p < 0, 001 e p = 0,001, respectivamente). Conclusão: A ecocardiografia com estresse físico oferece informações prognósticas adicionais em pacientes com teste ergométrico positivo para isquemia miocárdica. PMID:25352460

  5. Whales originated from aquatic artiodactyls in the Eocene epoch of India.

    Although the first ten million years of whale evolution are documented by a remarkable series of fossil skeletons, the link to the ancestor of cetaceans has been missing. It was known that whales are related to even-toed ungulates (artiodactyls), but until now no artiodactyls were morphologically close to early whales. Here we show that the Eocene south Asian raoellid artiodactyls are the sister group to whales. The raoellid Indohyus is similar to whales, and unlike other artiodactyls, in the structure of its ears and premolars, in the density of its limb bones and in the stable-oxygen-isotope composition of its teeth. We also show that a major dietary change occurred during the transition from artiodactyls to whales and that raoellids were aquatic waders. This indicates that aquatic life in this lineage occurred before the origin of the order Cetacea. PMID:18097400

    Este artigo apresenta os principais eventos ocorridos na história do ensino de astronomia nos cursos superiores que existiram no Brasil desde a chegada da Família Real portuguesa em 1808 até o final do período monárquico. Para compor esse esboço histórico, utilizamos, principalmente, livros didáticos, regulamentos, decretos e leis responsáveis pelas organizações dos conteúdos oferecidos e das carreiras dos responsáveis pela disciplina. Na análise do material empregado, investigamos a presença de concepções filosóficas e científicas, que podem ter norteado os conteúdos disciplinares. Não realizamos nenhuma comparação com o ensino de astronomia em outros países. Concluímos mostrando que o estudo de astronomia, durante o período monárquico, foi mais direcionado para a formação d engenheiros do que astrônomos. Gostaríamos de observar que o presente artigo não tem a pretensão de abordar o assunto de maneira completa e detalhada.

    African horse sickness (AHS) of equines is partly transmitted by the same culicoides species as Bluetongue (BT) disease in even-toed ungulates. Horses normally get seriously sick, with a high case fatality rate. Equine Encephalosis is another, but less-known viral disease of equines, caused by viruses of the same genus as BT and AHS. Like BT of serotype 8 in 2006, both diseases could theoretically be introduced to Europe anytime and spread rapidly then. After the lessons learnt from the most recent bluetongue outbreaks in Europe, the regulations and AHS-contingency plans in force must be updated. All stakeholders must be aware of the risks and take own measures to prevent a possible emergence of the diseases, and be prepared in case of an outbreak. PMID:20361395

  8. Mastritherium (Artiodactyla, Anthracotheriidae) from Wadi Sabya, southwestern Saudi Arabia; an earliest Miocene age for continental rift-valley volcanic deposits of the Red Sea margin

    A lower jaw fragment with its last molar (M/3) from the Baid formation in Wadi Sabya, southwestern Saudi Arabia, represents the first recorded occurrence in the Arabian Peninsula of an anthracotheriid artiodactyl (hippo-like, even-toed ungulate). This fossil is identified as a primitive species of Masritherium, a North and East African genus restricted, previously to the later early Miocene. This identification indicates that the age of the Baid formation, long problematical, is early Miocene and, moreover, shows that the age of the fossil site is earliest Miocene (from 25 to 21Ma). The Wadi Sabya anthracothere is the first species of fossil mammal recorded from western Saudi Arabia, and more important, it indicates an early Miocene age for the volcanic deposits of a continental rift-valley that preceded the initial sea-floor spreading of the Red Sea.

    A reduction in the number of digits has evolved multiple times in tetrapods, particularly in cursorial mammals that travel over deserts and plains, yet the underlying developmental mechanisms have remained elusive. Here we show that digit loss can occur both during early limb patterning and at later post-patterning stages of chondrogenesis. In the “odd-toed” jerboa and horse and the “even-toed” camel, expansive cell death sculpts the tissue around the remaining toes. In contrast, digit loss in the pig is orchestrated by earlier limb patterning mechanisms including down regulation of Ptch1 expression but no increase in cell death. Together these data demonstrate remarkable plasticity in the mechanisms of vertebrate limb evolution and shed light on the complexity of morphological convergence, particularly within the artiodactyl lineage.

    The paper summarizes data on hitherto assembled findings of Spirochaeta burgdorferi, the causal agent of Lyme disease in arthropods and the incidence of antibodies in birds and mammals. The authors evaluate some vectors and reservoir animals, incl. possible carriers. Borrelia burgdorferi was found so far in 30 species of Arthropoda, 13 species of mites (Acarina), 15 species of flies(Diptera), two species of fleas (Siphonaptera). The role of insects as vectors was not proved so far. Antibodies were detected in eight species of birds (Aves, Passeriformes) and in 22 mammalian species: one species of marsupiales (Marsupialia), 3 species of carnivores (Carnivora), seven species of rodents (Rodentia), two species of rabbits and hares (Lagomorpha), in 8 species of even-toed ungulates (Artiodactyla) and one species of odd-toed ungulates (Perissodactyla). The great majority of species comes from the non-arctic area. PMID:2646031

In even-toed ungulates (artiodactyls, including cattle), limbs are adapted for running as a consequence of progressive reduction of their distal skeleton to symmetrical and elongated middle digits with hoofed phalanges. Here we analyse bovine embryos to establish that polarized gene expression is progressively lost during limb development in comparison to the mouse. Notably, the transcriptional upregulation of the Ptch1 gene, which encodes a Sonic hedgehog (SHH) receptor, is disrupted specifically in the bovine limb bud mesenchyme. This is due to evolutionary alteration of a Ptch1 cis-regulatory module, which no longer responds to graded SHH signalling during bovine handplate development. Our study provides a molecular explanation for the loss of digit asymmetry in bovine limb buds and suggests that modifications affecting the Ptch1 cis-regulatory landscape have contributed to evolutionary diversification of artiodactyl limbs.

  13. Near-Earth Asteroids Astrometry with Gaia and Beyond

    NASA Astrophysics Data System (ADS)

    Bancelin, D.; Hestroffer, D.; Thuillot, W.

    2010-12-01

    Potentially Hazardous Asteroids (PHAs) are Near-Earth Asteroids (NEAs) caraterised by a Minimum Orbital Intersection Distance (MOID) with Earth less than 0,05 A.U and an absolute magnitude H<22. Those objects have sometimes a so significant close approach with Earth that they can be put on a chaotic orbit. This kind of orbit is very sensitive for exemple to the initial conditions, to the planetary theory used (for instance JPL's model versus IMCCE's model) or evento the numerical integrator used (Lie Series, Bulirsch-Stoer or Radau). New observations (optical, radar, fly-by or satellite mission) can improve those orbits and reduce the uncertainties on the Keplerian elements. We investigate here, the impact of the Gaia astrometric observations on the asteroid Apophis's orbit.

    A reduction in the number of digits has evolved many times in tetrapods, particularly in cursorial mammals that travel over deserts and plains, yet the underlying developmental mechanisms have remained elusive. Here we show that digit loss can occur both during early limb patterning and at later post-patterning stages of chondrogenesis. In the 'odd-toed' jerboa (Dipus sagitta) and horse and the 'even-toed' camel, extensive cell death sculpts the tissue around the remaining toes. In contrast, digit loss in the pig is orchestrated by earlier limb patterning mechanisms including downregulation of Ptch1 expression but no increase in cell death. Together these data demonstrate remarkable plasticity in the mechanisms of vertebrate limb evolution and shed light on the complexity of morphological convergence, particularly within the artiodactyl lineage.

    Em 06 de junho de 2000 (~15: 00-17: 00 UT), o Brazilian Solar Spectroscope (BSS) registrou uma explosão solar intensa no intervalo de freqüência de (1000-2000) MHz, com alta resolução temporal (100 ms) e espectral (5 MHz). A atividade solar relacionada a esta explosão associada à região ativa (AR) 9026 e classificada como X2.3 foi grande. O Ondrejov Observatory registrou rádio emissões até 4,5 GHz. O satélite SOHO registrou uma série de erupções solares, incluindo uma Ejeção de Massa Coronal (CME) tipo "full-halo" (~15: 54 UT). Explosões tipo II/IV também foram registradas. Na faixa de ondas decimétricas, este evento apresentou dois picos distintos (~15: 21 UT e ~16: 42 UT). O primeiro pico coincide com a explosão registrada em raios-X moles (GOES) e em raios-X duros (Yohkoh). Os espectros dinâmicos com alta resolução do BSS revelaram várias estruturas finas, principalmente emissões tipo "zebra" e "fibra", rádio pulsações, emissões tipo III e do único caso de emissões "zebra" harmônicas observado na faixa decimétrica. Neste trabalho, analisamos a evolução temporal e o comportamento global do evento de 06 de junho de 2000, com ênfase na identificação e associação da ocorrência de cada tipo de estrutura fina registrada em rádio com cada etapa da explosão. Resultados preliminares mostraram que, na fase pré-flare, as estruturas finas apresentaram taxa de deriva negativa (~ 70-190 MHz/s). As emissões tipo "zebra" concentram-se na fase de descida do primeiro pico impulsivo e na de subida do segundo pico. Enquanto que as emissões tipo "fibra" ocorrem em ambas fases, mas preferivelmente durante a fase de descida. Os resultados serão apresentados e discutidos.

    Dealing with complex environmental issues frequently inhibits redevelopment of industrial sites in urban settings. In 1993, the City of Chicago (City) Department of Planning and Development, Department of Buildings, and Mayor`s Office joined the Department of Environment to investigate reuse of former industrial/commercial properties (brownfields) suspected of environmental or industrial contamination. The collective result is the Brownfield Program, a three-pronged initiative: Brownfield Pilot Program, Brownfield Forum, and Brownfield Research. Black and Veatch Waste Science, Inc. (Waste Science) carried the Brownfield Program forward by performing a Phase 1 environmental site assessment for the City on one of five pilot sites. Waste Science subsequently completed a Phase 2 environmental site assessment and Phase 3 site remediation at the site. Waste oil and PCB-contaminated soil was removed.

  7. Bikes, helmets, and public health: decision-making when goods collide.

    How ought public officials address policy choices that entail trade-offs between desirable public health goods? Increasing cycling improves public health both by promoting physical activity and by decreasing vehicle use, thus reducing vehicular emissions. Proponents of bicycle helmets argue that, used properly, they protect individual cyclists; however, there is concern that mandating helmet use may result in a decrease in cycling. In 2012, New York City Mayor Michael Bloomberg opposed a bicycle helmet mandate, concerned that it would have a negative impact on the city's cycling rate, which he had sought to increase. The mayor did not explain his rationale, leaving constituents unsure why he opposed the proposal. This case study underscores the challenge of creating public policy in the context of competing public health goods. PMID:24825196

    Existen prejuicios en relación con la vejez, incluso entre los profesionales que se dedican a la gerontología. Uno común y peligroso es considerar que los viejos son todos enfermos o discapacitados.La relación médico-paciente es la piedra angular de la práctica y ética médicas. Para alcanzar el respeto por los adultos mayores es necesaria una medicina prudente, basada en una práctica en la cual la reflexión ética y clínica pueda contribuir. Esto último es posible si se hacen valer los derechos del adulto mayor, en particular como paciente para la toma de decisiones. PMID:20379380

    2010-01-01

    The son of a Lithuanian artist, Antanas Mockus was the president of the National University in Colombia before he became mayor of Bogotá in 1995. As mayor, he transformed the city into a huge classroom, not only bringing to his administration a new view of governing but also transforming the way people exercised their citizenship. Mockus resorted to a creative communicative and pedagogical effort to change the citizens' hearts and minds in favor of peaceful coexistence and legal compliance. Symbols, metaphors, and humor became the language through which the administration would enforce its measures to deal with urban violence. Unconventional techniques, such as a symbolic vaccine against domestic violence and the use of mimes to control traffic circulation and create a sense of shame among those who committed infractions, helped to stop crime and develop a new sense of citizenship.

    In spite of abundant archeological material available in Mexico, archeomagnetic studies are extremely scarce. In this work, we conducted systematic archeointensity measurements on some well-known archeological sites in central and eastern Mexico (e.g., Teotihuacan, Templo Mayor among others) to contribute to the relative and absolute chronology of Mesoamerica. Our sampling strategy was guided largely by Linda Manzanilla's detailed study of two of the most important archeological sites in Central Mexico, Teotihuacan, and Templo Mayor, since we sampled only materials that are already studied and provide more or less coherent archeological ages. Moreover, we incorporated data from some Mexican lava flows that erupted during historic times in order to extend the archeointensity master curve for Mexico and Mesoamerica to the present.

  6. Detecção da fase impulsiva de uma explosão solar gigante até 405 GHz

    A explosão ocorrida no dia 25/08/2001 foi uma das mais intensas do presente ciclo solar em ondas de rádio de altas frequências. Foram medidas em ondas milimétricas e submilimétricas, aproximadamente, 105 e vários milhares de unidades de fluxo solar, respectivamente. Apresentamos um estudo deste evento em múltiplas frequências, desde microondas (1GHz), até ondas submilimétricas (405 GHz) detectadas pelo Telescópio Solar para ondas Submilimétricas (SST). Esta base de dados foi complementada utilizando-se o experimento Yohkoh, incluindo a emissão em raios-X duros e raios-g (até 100 MeV), e imagens em raios-X moles da região ativa envolvida. Enfocamos e discutimos principalmente os seguintes aspectos da fase impulsiva do evento: (i) as implicações deduzidas do espectro eletromagnético, obtido pela primeira vez até 405 GHz; (ii) a dinâmica da região ativa. Os resultados mostram que para explicar o espectro rádio observado, são necessários entre 3.5×1037 e 1.5×1039 elétrons acelerados acima de 20 keV em uma região de campo magnético entre 300 e 800 Gauss. A estimativa do fluxo de fótons que seria produzido por estes elétrons, mostra que grande parte deles não precipitou na baixa atmosfera. A evolução temporal da emissão em raios-X moles revela que a configuração magnética da região ativa foi muito dinâmica durante a fase impulsiva da explosão. Em particular, mostramos que a produção dos elétrons altamente energéticos foi iniciada junto com a aparição, na baixa coroa solar, de um novo sistema compacto de estruturas magnéticas. Este fato sugere que os locais de aceleração estão localizados na baixa atmosfera do Sol, como resultado da interação entre o novo sistema compacto e o campo magnético ambiente da região ativa.

    Com base em (Brandt et al, 1992), centenas de imagens do cometa P/Halley foram visualmente analisadas, objetivando examinar possíveis perturbações magnetohidrodinâmicas ao longo da cauda do tipo I. Do total de 1439 imagens, abrangendo o período entre 16 de outubro de 1982 e 12 de fevereiro de 1991, foram escolhidas 531 do período entre 17 de setembro de 1985 e 06 de julho de 1986 por mostrarem cauda bem desenvolvida e rica de estruturas morfológicas. Nelas constatou-se a existência de 124 estruturas ondulatórias (trens de onda) ao longo da cauda principal, 27 ao longo de caudas secundárias, 109 ondas solitárias (sólitons) ao longo da cauda principal, 36 ao longo de caudas secundárias, 12 caudas do tipo Swan, 47 eventos de desconexão e 23 regiões de adensamento ("knots"). Foi examinada a correlação temporal entre esses diferentes tipos de eventos. Os de desconexão foram analisados isoladamente. Seus movimentos próprios foram calculados, bem como os seus instantes iniciais, o que nos permitiu inferir a passagem do cometa pela fronteira entre setores magnéticos distintos. A velocidade do plasma cometário desconectado foi corrigida dos efeitos de projeção e correlacionada com a distância heliocêntrica do cometa. Também foi investigada a periodicidade de ocorrência das desconexães, e constatado que sua distribuição é bimodal. Por fim, a possibilidade dos modos de propagação de ondas MHD "sausage" e "kink" superficiais ou volumétricas, é discutida no contexto das descontinuidades magnéticas tangenciais. - Brandt, J.C., Niedner Jr., M.B., Rahe, J.: The International Halley Watch Atlas of Large-Scale Phenomena.

    O High Energy Transient Explorer (HETE) é o primeiro satélite inteiramente dedicado ao estudo das explosões cósmicas de raios gama (ECRGs). Lançado em 9 de outubro de 2000, o HETE possui instrumentação capaz de observar as ECRGs desde o UV até raios gama e localizá-las com precisão de ~ 1-10 minutos de arco. As localizações das ECRGs detectadas são disseminadas rapidamente (em alguns segundos) pela Internet através de uma rede de estações de recepção ao longo do equador. A participação brasileira nesse projeto se dá através da montagem e operação de uma estação de recepção em Natal, RN, e da participação na equipe científica da missão. Neste trabalho são apresentados resultados da observação pelo HETE de duas ECRGs: GRB 021004 e GRB 021211. A GRB021004 foi detectada em raios gama pelo HETE em 4 de outubro de 2002 e localizada em raios-X em apenas 48 s, quando a emissão de raios gama ainda estava se processando. A explosão, relativamente brilhante e longa, durou aproximadamente 100 s. Um transiente óptico de magnitude 15 foi detectado no local da explosão nove minutos após o evento, e observações realizadas após 7 horas determinaram um desvio para o vermelho de absorção de 1,6. O GRB021004 foi o burst mais bem observado até o momento e suas observações em vários comprimentos de onda têm sido fundamentais para o aprimoramento dos modelos de ECRGs. O GRB21211, um burst brilhante e rico em raios-X, foi detectado em 11 de dezembro de 2002 e localizado em raios-X em 22 s após o início do evento. A duração do burst foi de 2,3 s em altas energias (85 a 400 keV) e de 8,5 s em baixas energias (2 a 10 keV). Caso essa explosão não tivesse sido rapidamente localizada pelo HETE, ela teria sido classificada como "opticamente escura", já que o transiente óptico decaiu rapidamente de R < 14 a R»19 dentro dos primeiros 20 minutos e já estava mais fraco do que R»23 depois de 24 horas da ocorrência do burst. Serão discutidas as implicações desse resultado nos modelos de afterglows de ECRGs.

  9. População estelar jovem em galáxias irregulares próximas

    A análise do conteúdo estelar de galáxias próximas através da fotometria das suas estrelas resolvidas nos fornece informações importantes sobre a história de formação estelar e os processos de formação estelar em galáxias, que estão diretamente ligados ao estudo de evolução de galáxias. Quando nenhuma estrela puder ser resolvida o método mais poderoso consiste na análise do conteúdo estelar integrado das galáxias através das suas cores integradas em conjunto com informação espectroscópica que combinados com modelos de síntese evolutiva podem restringir simultaneamente a função de massa inicial (IMF) e a taxa de formação estelar (SFR). Nesse contexto, galáxias do tipo tardio, em particular, irregulares, são relevantes por várias razões: elas são objetos relativamente simples, com alta atividade de formação estelar e são objetos relativamente jovens (geralmente apresentam baixas abundâncias de elementos pesados e grande quantidade de gás). Apresentamos uma análise fotométrica de uma amostra de 7 galáxias do tipo tardio do universo local (NGC 2366, NGC 4395, NGC 4656, NGC 4214, NGC 4236, HOII, IC2574) que foram observadas com uma boa resolução espacial nas bandas B, V e R no telescópio Isaac Newton de 2.5m de Roque de los Muchachos nas Ilhas Canárias, Espanha. A distribuição espacial da população estelar jovem dessas galáxias é discutida sobre os pontos de vista dos íindices de cor integrados e dos seus diagramas cor magnitude, que comparados com isócronas teóricas, nos fornecem informações sobre os eventos de formação estelar, como por exemplo, indicações sobre a idade dos mesmos. As principais conclusões do trabalho podem ser resumidas em: (i) As galáxias irregulares possuem formação estelar recente (FE) espalhada ocorrendo nos últimos 50 Manos; (ii) A formação estelar em galáxias irregulares não é auto-propagante em escalas globais ( > 100 pc) ; (iii) A FE pode ser auto-regulável em escalas espaciais de poucas dezenas de parsec; (iv) As galáxias irregulares sofreram um evento principal de FE há 1010 anos atrás, o que implica que houve um momento na evolução do universo onde a maior parte das estrelas se formaram em galáxias.

    1985-01-01

    The history of research on coral reefs of the Western Atlantic is the history of geology for the same period write small. The inter-related, pioneer researchers were led by the Agassizs, Louis and his son Alexander, who explored and described reefs in Florida and the Bahamas. Among their followers were Alfred G. Mayor the founder-director and premier researcher of the Carnegie Laboratory in the Dry Tortugas; C.F. Hartt who first described southernmost reefs off Brazil; Louis Pourtales whose dredging off the Florida coast stimulated interest in organic limestones; and T. Wayland Vaughan whose research ranged from coral biology to the regional geology and history of reefs. The initial 19th century research was sparked by a combination of practical and scientific questions and the what and where of exploration. To build lighthouses on the wreck-strewn Florida reefs one needs to know their foundations. Is the present-day Florida platform a result of reef growth during subsidence a la Darwin or are the reefs merely icing on a limestone cake. In the second phase of research extending from the early 1900's to 1940's, the singular aspects are two dynamic researchers, Alfred Mayor and T. Wayland Vaughan and the Carnegie Institution's Marine Biology Laboratory in the Dry Tortugas. Mayor through his own biological research and his stimulations of other scientists made the Carnegie Laboratory the world center for reef research. Vaughan pioneered connections between reef-building corals, reef deposits and their logical record.

    Malignant catarrhal fever (MCF) is an infectious disease in even-toed ungulates including domestic cattle and wild living ruminants, which repeatedly also occurred in zoological gardens in Europe. The goal of the study presented here was to determine whether wild ruminants--here in the sense of non-domesticated ruminant species in zoological collections--normally not known as carriers of MCF viruses, may carry and shed these viruses and thus might play a possible role as source of infection. To this end, swap samples from eye, nose, and rectum, and also some blood samples, collected from different ruminant species in 11 zoological gardens and animal parks in the years 2007 to 2009 were examined with real-time polymerase chain reaction (rt-PCR) for the presence of the genome of viruses known to cause MCF most frequently: alcelaphine herpesvirus 1 (AIHV-1), ovine herpesvirus 2 (OvHV-2), caprine herpesvirus 2 (CpHV-2) and malignant catarrhal fever virus--white-tailed deer (MCFV-WTD) The results of this investigation showed the presence of the genomes of one--or more--of these MCF viruses in five of the contributing institutions. A total of 28 samples (12.84%) proved to be positive. In no case, the presence of the AIHV-1 genome was detected. For the first time, the presence of the MCFV-WTD genome was demonstrated in goats, indicating a carrier state of this animal species. PMID:26054228

  13. Early Miocene hippopotamids (Cetartiodactyla) constrain the phylogenetic and spatiotemporal settings of hippopotamid origin.

    The affinities of the Hippopotamidae are at the core of the phylogeny of Cetartiodactyla (even-toed mammals: cetaceans, ruminants, camels, suoids, and hippos). Molecular phylogenies support Cetacea as sister group of the Hippopotamidae, implying a long ghost lineage between the earliest cetaceans (approximately 53 Ma) and the earliest hippopotamids (approximately 16 Ma). Morphological studies have proposed two different sister taxa for hippopotamids: suoids (notably palaeochoerids) or anthracotheriids. Evaluating these phylogenetic hypotheses requires substantiating the poorly known early history of the Hippopotamidae. Here, we undertake an original morphological phylogenetic analysis including several "suiform" families and previously unexamined early Miocene taxa to test previous conflicting hypotheses. According to our results, Morotochoerus ugandensis and Kulutherium rusingensis, until now regarded as the sole African palaeochoerid and the sole African bunodont anthracotheriid, respectively, are unambiguously included within the Hippopotamidae. They are the earliest known hippopotamids and set the family fossil record back to the early Miocene (approximately 21 Ma). The analysis reveals that hippopotamids displayed an unsuspected taxonomic and body size diversity and remained restricted to Africa during most of their history, until the latest Miocene. Our results also confirm the deep nesting of Hippopotamidae within the paraphyletic Anthracotheriidae; this finding allows us to reconstruct the sequence of dental innovations that links advanced selenodont anthracotheriids to hippopotamids, previously a source of major disagreements on hippopotamid origins. The analysis demonstrates a close relationship between Eocene choeropotamids and anthracotheriids, a relationship that potentially fills the evolutionary gap between earliest hippopotamids and cetaceans implied by molecular analyses.

    Projeto desenvolvido em 1981 por professores da Unicamp, sob a coordenação do Prof. Dr. Carlos Alfredo Argüello propunha a instalação de um Planetário em Campinas. Convênio firmado em 1982 entre a Unicamp, a Prefeitura de Campinas, a Funcamp e a Academia de Ciências do Estado de São Paulo, possibilitou a aquisição de um planetário Zeiss ZKP2, através do MEC, e em 28 de outubro de 1987 foi inaugurado o Planetário de Campinas. Desde então várias atividades de ensino e divulgação da Astronomia foram desenvolvidas regularmente. A verificação dos registros das atividades realizadas mostra um alto índice de atendimento, considerada a capacidade das instalações (sala de projeção para 60 pessoas, auditório com 45 poltronas e hall de exposições). As atividades dirigidas ao público, estudantes e professores, atenderam cerca de 400.000 participantes nos quase 16 anos de sua existência. Além de sessões públicas e escolares, com duração de 1 hora, são oferecidas às escolas vários outros tipos de atividades, com duração de 2,5 horas. Abordam diversos temas e são dirigidas a diferentes níveis de escolaridade. Cursos para o público e para professores, palestras, exposições e eventos especiais completam o quadro de atividades regulares. Mesmo enfrentando quase sempre dificuldades financeiras e administrativas verifica-se que o Planetário de Campinas realizou um trabalho quantitativamente e qualitativamente satisfatório, prestando bom serviços à comunidade de Campinas e de outras cidades de São Paulo e outros Estados. Isso é também atestado pela grande procura de reservas para suas atividades.

    The okapi is an endangered, evolutionarily distinctive even-toed ungulate classified within the giraffidae family that is endemic to the Democratic Republic of Congo. The okapi is currently under major anthropogenic threat, yet to date nothing is known about its genetic structure and evolutionary history, information important for conservation management given the species' current plight. The distribution of the okapi, being confined to the Congo Basin and yet spanning the Congo River, also makes it an important species for testing general biogeographic hypotheses for Congo Basin fauna, a currently understudied area of research. Here we describe the evolutionary history and genetic structure of okapi, in the context of other African ungulates including the giraffe, and use this information to shed light on the biogeographic history of Congo Basin fauna in general. Using nuclear and mitochondrial DNA sequence analysis of mainly non-invasively collected samples, we show that the okapi is both highly genetically distinct and highly genetically diverse, an unusual combination of genetic traits for an endangered species, and feature a complex evolutionary history. Genetic data are consistent with repeated climatic cycles leading to multiple Plio-Pleistocene refugia in isolated forests in the Congo catchment but also imply historic gene flow across the Congo River.

    Haemosporida parasites of even-toed ungulates are diverse and globally distributed, but since their discovery in 1913 their characterization has relied exclusively on microscopy-based descriptions. In order to bring molecular approaches to bear on the identity and evolutionary relationships of ungulate malaria parasites, we conducted Plasmodium cytb-specific nested PCR surveys using blood from water buffalo in Vietnam and Thailand, and goats in Zambia. We found that Plasmodium is readily detectable from water buffalo in these countries, indicating that buffalo Plasmodium is distributed in a wider region than India, which is the only area in which buffalo Plasmodium has been reported. Two types (I and II) of Plasmodium sequences were identified from water buffalo and a third type (III) was isolated from goat. Morphology of the parasite was confirmed in Giemsa-reagent stained blood smears for the Type I sample. Complete mitochondrial DNA sequences were isolated and used to infer a phylogeny in which ungulate malaria parasites form a monophyletic clade within the Haemosporida, and branch prior to the clade containing bird, lizard and other mammalian Plasmodium. Thus it is likely that host switching of Plasmodium from birds to mammals occurred multiple times, with a switch to ungulates independently from other mammalian Plasmodium. PMID:26996979

    The horse is a common domestic animal whose anatomy has been studied since the XVI century. However, a modern neuroanatomy of this species does not exist and most of the data utilized in textbooks and reviews derive from single specimens or relatively old literature. Here, we report information on the brain of Equus caballus obtained by sampling 131 horses, including brain weight (as a whole and subdivided into its constituents), encephalization quotient (EQ), and cerebellar quotient (CQ), and comparisons with what is known about other relevant species. The mean weight of the fresh brains in our experimental series was 598.63 g (SEM ± 7.65), with a mean body weight of 514.12 kg (SEM ± 15.42). The EQ was 0.78 and the CQ was 0.841. The data we obtained indicate that the horse possesses a large, convoluted brain, with a weight similar to that of other hoofed species of like mass. However, the shape of the brain, the noteworthy folding of the neocortex, and the peculiar longitudinal distribution of the gyri suggest an evolutionary specificity at least partially separate from that of the Cetartiodactyla (even-toed mammals and cetaceans) with whom Perissodactyla (odd-toed mammals) are often grouped.

ABSTRACT A common believe in cosmology is that gravitational radiation in considerable quantities is being produced within the galaxies. Ifgravitational radiation production has been running since the galaxy formation epoch, at least, its cosmological effects can be assesed with simplicity and elegance by representing the production of radiation and, therefore, its interaction with ordinary matter phenomenologically through a polytropic equation of state as shown already elsewhere. We present in this paper the numerical results of such a model. K words: COSMOLOGY - GRAVITATION

    The emergence of Cetacea in the Paleogene represents one of the most profound macroevolutionary transitions within Mammalia. The move from a terrestrial habitat to a committed aquatic lifestyle engendered wholesale changes in anatomy, physiology, and behavior. The results of this remarkable transformation are extant whales that include the largest, biggest brained, fastest swimming, loudest, deepest diving mammals, some of which can detect prey with a sophisticated echolocation system (Odontoceti - toothed whales), and others that batch feed using racks of baleen (Mysticeti - baleen whales). A broad-scale reconstruction of the evolutionary remodeling that culminated in extant cetaceans has not yet been based on integration of genomic and paleontological information. Here, we first place Cetacea relative to extant mammalian diversity, and assess the distribution of support among molecular datasets for relationships within Artiodactyla (even-toed ungulates, including Cetacea). We then merge trees derived from three large concatenations of molecular and fossil data to yield a composite hypothesis that encompasses many critical events in the evolutionary history of Cetacea. By combining diverse evidence, we infer a phylogenetic blueprint that outlines the stepwise evolutionary development of modern whales. This hypothesis represents a starting point for more detailed, comprehensive phylogenetic reconstructions in the future, and also highlights the synergistic interaction between modern (genomic) and traditional (morphological+paleontological) approaches that ultimately must be exploited to provide a rich understanding of evolutionary history across the entire tree of Life.

  1. Evidence from milk casein genes that cetaceans are close relatives of hippopotamid artiodactyls.

    The inferred transition from terrestrial hoofed mammal to fully aquatic cetacean has been intensively studied with fossil evidence. However, large sections of this remarkable evolutionary sequence are missing. Phylogenetic analysis of extant taxa may help to fill in some of these gaps. In this report, kappa-casein (exon 4) and beta-casein (exon 7) milk protein genes from cetaceans and other placental mammals were PCR-amplified, sequenced, and aligned to previously published sequences. Phylogenetic analyses of the casein data suggest that hippopotamid artiodactyls are more closely related to cetaceans than to other artiodactyls (even-toed hoofed mammals). An analysis of the nuclear casein sequences combined with published mitochondrial cytochrome b DNA sequences also supports the Cetacea/Hippopotamidae sister group. This affinity implies that some of the aquatic traits of cetaceans were derived in the common ancestor of Cetacea and Hippopotamidae. An extant "missing link" to Cetacea may have been overlooked by science since the description of the semiaquatic Hippopotamus in 1758. Paleontological information is grossly inconsistent with this hypothesis. If the casein phylogeny is accurate, large gaps in the fossil record as well as extensive morphological reversals and convergences must be acknowledged. PMID:8752004

    This study was conducted to evaluate the prevalence of antibodies against Borrelia bugdorferi (Bb) s.l. and tick-borne encephalitis virus (TBEV) in zoo animals in the Czech Republic. We collected 133 serum samples from 69 animal species from 5 zoos located in different parts of the country. The samples were obtained from even-toed ungulates (n=78; 42 species), odd-toed ungulates (n=32; 11 species), carnivores (n=13; 9 species), primates (n=2, 2 species), birds (n=3; 2 species), and reptiles (n=5; 3 species). A high antibody prevalence (60%) was observed for Bb s.l. On the other hand, only two animals had TBEV-specific antibodies: a markhor (Capra falconeri) and a reindeer (Rangifer tarandus), both from the same zoo, located in an area endemic for TBEV. Both of these animals were also positive for Bb s.l. antibodies. Our results indicate that a high number of animal species in the Czech zoos were exposed to Bb s.l. and that TBEV infection occurred at least in one of the investigated zoos. Considering the pathogenic potential of these two tick-borne pathogens, clinical and serological monitoring should be continued, and therapeutic and preventive measures should be taken when necessary.

    Foot-and-mouth disease (FMD) is caused by an RNA virus of the genus Aphthovirus; 7 immunologically distinct serotypes of the virus have been identified. Susceptible species are mainly domestic and wild even-toed ungulates, such as cattle, sheep, goats, pigs, bison, and deer. All body fluids of infected animals can contain the virus and are considered infective. The primary mode of transmission is animal-to-animal transmission through inhalation or ingestion of aerosols containing the virus. The virus can also be spread mechanically by contaminated organic debris and fomites and can survive for 48 hours on human oral and nasal mucosa and be spread to uninfected animals in this manner. There is a rapid progression of clinical signs after an animal becomes infected, and the virus spreads rapidly throughout a herd. Clinical signs include excessive salivation; fever; vesicles and erosions of the oral and nasal mucosa, coronary band, interdigital area, and teats; lameness; sloughing of claws; reluctance to move; anorexia; mastitis; decreased milk production; and abortion or weak newborns. In mature animals, FMD has high morbidity and low mortality rates. Infected animals can become inapparent carriers of the virus. PMID:15112774

    Delta-toxin, an extracellular hemolysin released by Clostridium perfringens type C, was purified from culture supernatant fluid by sequential ammonium sulfate precipitation, thiol-Sepharose gel chromatography, isoelectric focusing, and Sephadex G-75 gel filtration. The purified preparation had a specific activity of 320,000 hemolytic units per mg of protein and was homogeneous, as determined by immunochemical and electrophoretic tests. This toxin was characterized as a single polypeptide chain composed of 391 amino acid residues, 30% of which were hydrophobic. The molecular weight was found to be 42,000, and the isoelectric point was pH 9.1. Delta-toxin appeared to be amphiphilic by charge shift electrophoresis in a three-detergent system. It was immunogenic in rabbits and lethal to mice at a dose of 0.12 micrograms. The lytic activity of delta-toxin was restricted to erythrocytes of even-toed ungulates (sheep, goats, and pigs). This activity was inhibited by GM2 ganglioside but not by other gangliosides, cholesterol, lecithin, or sphingomyelin. Images PMID:6260669

Por lo tanto, el análisis de estructuras coronales cuasiestacionarias en la corona da importante información sobre el campo magnético y la actividad asociada. Se trata de poner límites a los modelos teóricos existentes mediante el estudio de distintas estructuras en la corona interior. En agosto de 1997 comenzó a operar el coronógrafo solar (MICA) en El Leoncito como parte del Observatorio Solar Alemán-Argentino. Desde su instalación obtiene imágenes de la corona solar (1.05 a 2.0 radios solares) en 2 líneas espectrales correspondientes a la emisión de Fe XIV y Fe X. El instrumento puede obtener imágenes cada minuto por lo que es ideal para estudiar procesos rápidos. Presentamos observaciones recientes que muestran la capacidad del coronógrafo así como la evolución de algunos eventos dinámicos observados por MICA.

  9. Early Miocene hippopotamids (Cetartiodactyla) constrain the phylogenetic and spatiotemporal settings of hippopotamid origin

    The affinities of the Hippopotamidae are at the core of the phylogeny of Cetartiodactyla (even-toed mammals: cetaceans, ruminants, camels, suoids, and hippos). Molecular phylogenies support Cetacea as sister group of the Hippopotamidae, implying a long ghost lineage between the earliest cetaceans (∼53 Ma) and the earliest hippopotamids (∼16 Ma). Morphological studies have proposed two different sister taxa for hippopotamids: suoids (notably palaeochoerids) or anthracotheriids. Evaluating these phylogenetic hypotheses requires substantiating the poorly known early history of the Hippopotamidae. Here, we undertake an original morphological phylogenetic analysis including several “suiform” families and previously unexamined early Miocene taxa to test previous conflicting hypotheses. According to our results, Morotochoerus ugandensis and Kulutherium rusingensis, until now regarded as the sole African palaeochoerid and the sole African bunodont anthracotheriid, respectively, are unambiguously included within the Hippopotamidae. They are the earliest known hippopotamids and set the family fossil record back to the early Miocene (∼21 Ma). The analysis reveals that hippopotamids displayed an unsuspected taxonomic and body size diversity and remained restricted to Africa during most of their history, until the latest Miocene. Our results also confirm the deep nesting of Hippopotamidae within the paraphyletic Anthracotheriidae; this finding allows us to reconstruct the sequence of dental innovations that links advanced selenodont anthracotheriids to hippopotamids, previously a source of major disagreements on hippopotamid origins. The analysis demonstrates a close relationship between Eocene choeropotamids and anthracotheriids, a relationship that potentially fills the evolutionary gap between earliest hippopotamids and cetaceans implied by molecular analyses.

    Introducción: El temblor puede ser un desorden incapacitante y el tratamiento de primera línea para estos pacientes es farmacológico. Sin embargo, este tratamiento puede llevar a una reducción satisfactoria del temblor en sólo el 50% de los pacientes con temblor esencial. La talamotomía era el tratamiento de elección para el temblor refractario al tratamiento médico hasta que comenzó a utilizarse la estimulación cerebral profunda (ECP) del núcleo ventral intermedio (Vim) del tálamo. En la actualidad, raramente se realiza la talamotomía. Métodos: Este artículo es una revisión no sistemática de las indicaciones, resultados, parámetros de programación y técnica quirúrgica de la ECP del Vim para el tratamiento del temblor. Resultados: Aunque los resultados clínicos son similares usando la talamotomía o la ECP del Vim, la primera causa más efectos adversos que la última. Además, la ECP puede ser usada bilateralmente, mientras que la talamotomía tiene un alto riesgo de causar disartria cuando se realiza de ambos lados. La ECP del Vim logró una adecuada mejoría del temblor en varias series de pacientes con temblor causado por temblor esencial, enfermedad de Parkinson o esclerosis múltiple. Además del Vim, hay otros blancos que están siendo usados por varios autores, tales como la zona incerta y las radiaciones prelemniscales. Conclusión: La ECP del Vim es un tratamiento útil para el temblor incapacitante refractario al tratamiento médico. Es esencial realizar una precisa selección de pacientes, así como utilizar una técnica quirúrgica correcta. Aún se desconoce el mejor blanco estereotáctico para el temblor, aunque el Vim es el más usado. PMID:25165613

    We report on a statistical analysis of the engagement in the electoral processes of all Brazilian cities by considering the number of party memberships and the number of candidates for mayor and councillor. By investigating the relationships between the number of party members and the population of voters, we have found that the functional forms of these relationships are well described by sublinear power laws (allometric scaling) surrounded by a multiplicative log-normal noise. We have observed that this pattern is quite similar to those we previously reported for the relationships between the number of candidates (mayor and councillor) and population of voters [Europhys. Lett.EULEEJ0295-507510.1209/0295-5075/96/48001 96, 48001 (2011)], suggesting that similar universal laws may be ruling the engagement in the electoral processes. We also note that the power-law exponents display a clear hierarchy, where the more influential is the political position the smaller is the value of the exponent. We have also investigated the probability distributions of the number of candidates (mayor and councillor), party memberships, and voters. The results indicate that the most influential positions are characterized by distributions with very short tails, while less influential positions display an intermediate power-law decay before showing an exponential-like cutoff. We discuss the possibility that, in addition to the political power of the position, limitations in the number of available seats can also be connected with this changing of behavior. We further believe that our empirical findings point out to an under-representation effect, where the larger the city is, the larger are the obstacles for more individuals to become directly engaged in the electoral process.

  12. Effects of hydrothermal alteration on the magnetic properties of rocks : case studies for stratabound and porphyry copper deposits of chile

    In nature, the great mayority of metallic ore deposits are of hydrothermal origin, hence they present a mayor or minor degree of associated hydrothermal alteration. Alteration is metasomatic and affects the mineralogical and chemical composition of the host rock, be it by replacement of host rock minerals or by crystallization of hydrothermal minerals. Many types of hydrothermal alteration associations exist for many types of metallic ore deposits, depending upon factors such as composition and thermodynamic characteristics of hydrothermal fluids, lithology and permeability of host rock, temperature and depth of emplacement, among others. These processes of hydrothermal alteration, understood in terms of partial to total metasomatism, affect in a mayor to minor degree the "ferromagnetic" (sensus latus) minerals and/or generate "ferromagnetic" minerals, in such case that the magnetic properties of the rock are affected. This concept is dealt in exploration by use of magnetic surveys at a practical level: the effects of hydrothermal alteration, being of local scale, must present contrast of magnetic properties (susceptibility and remanent magnetization) with respect to the hosting country rock. This being true, does not take into consideration the magnetic properties of rocks at a mineral scale, observeable constrast of magnetic surveys much dependant of scale and detail of data (ie. aeromagnetic survey vs. ground survey). A study of the particular magnetic properties associated with different types of alteration was done for two stratabound copper deposits (Carolina de Michilla and Mantos Blancos, northern Chile) and for the giant porphyry copper deposits Chuquicamata (northern Chile) and El Teniente (central Chile). The objetives were to determine the effects of hydrothermal alteration on "ferromagnetic" minerals. Preliminary results of these effects and relationships are presented, with a brief discussion on the implications of magnetic property contrast due to locallized changes of magnetic susceptibility and remanence, in terms of exploration magnetic surveys and scale at which contrast can actually be detected.

    New paleomagnetic data from Permo-Triassic and Late Cretaceous rocks yield a consistent trend of vertical-axis-tectonic-rotations which are consistent with the Central Andean Rotation Pattern (CARP). However, three sites in the Tuina Formation and one site in the Purilactis Group record large rotations (80°). These mayor rotations are probably due to dextral-transpressive deformation occurring in close relation with the Incaic tectonic phase. Consequently, it is possible to infer that previous tectonic phases Peruvian and K-T would not have produced significant tectonic rotations in the area.

  14. From protest to programs: neighborhood associations in a Brazilian municipality.

    The examples of community participation and organization in Brazil reflect the benefits to health and education programs and land entitlement. The community and government were working together toward self-improvement. An alliance was formed between neighborhood groups and a reform mayor. The result was an end to clientelism, stronger community organization, and local participation in designing and implementing development programs. The neighborhood groups were located in Cambe, which is a region located within the metropolitan area of Londrina, the 3rd largest city in southern Brazil. Mechanization of agriculture and extensive cattle ranching had caused migration into the area. Population increased 60% during the 1980s. The poorest neighborhoods were Jardim Tupy, Santo Amaro, and Novo Bandeirantes. Jardim Tupy was the poorest, and in 1980 a neighborhood association was formed to demand infrastructure and public services. The clientelism mayor and national government refused aid. When the association sued over a motor vehicle accident involving farm workers living in the community and won, there was momentum to change city hall. Support was given to the reform mayor who won and agreed to community demands for a community garden. The garden became a model for 14 others in Cambe and led to a strong neighborhood association which learned the strength of unity. The mayor rewarded good neighborhood organization with increases in public goods and services. The Catholic Church became involved in Jardim Tupy with a Pastoral of the Child program to reduce infant and child mortality rates. Health improvements in the community are attributed to the neighborhood association, the Pastoral of the Child, the local Catholic parish, and a thaw in the relationship with local government.

    Arnal, E. M.

    Los estudios llevados a cabo en la transición del hidrógeno neutro a ?~21-cm han contribuído a incrementar nuestro conocimiento acerca de las propiedades globales del medio interestelar, sea este galáctico o extragaláctico. Avances en este campo han sido provocados, a menudo, por la puesta en servicio de radiotelescopios que poseen una mayor resolución angular. Aquí se presenta una propuesta para desarrollar un nuevo instrumento, un interferómetro, que permitirá abrir nuevas líneas de investigación. Este instrumento combinará la técnica de síntesis de apertura con la de espectroscopía de correlación digital, para alcanzar una resolución angular de 1' y un campo de visión de ~1o.7.

    We explore the use of collocated GPS and seismic sensors for earthquake monitoring and early warning. The GPS and seismic data collected during the 2011 Tohoku-Oki (Japan) and the 2010 El Mayor-Cucapah (Mexico) earthquakes are analyzed by using a tightly-coupled integration. The performance of the integrated results is validated by both time and frequency domain analysis. We detect the P-wave arrival and observe small-scale features of the movement from the integrated results and locate the epicenter. Meanwhile, permanent offsets are extracted from the integrated displacements highly accurately and used for reliable fault slip inversion and magnitude estimation. PMID:24284765

    Oxytocinase has been reported to hydrolyse the peptide hormone oxytocin (OT). We have previously described changes in oxytocinase activity in human breast cancer, where a highly significant increase occurred in tumoral tissue. In the present work, we analysed oxytocinase activity in serum of rats with breast cancer induced by N-methyl-nitrosourea (NMU). We also correlated these data with the number and size of tumors and the body weight of the animals to evaluate the putative value of this activity as a biological marker of the disease. Our results confirm the involvement of OT in carcinogenesis and suggest a mayor role for oxytocinase activity in the development of breast cancer. PMID:15234194

    This year marks the 20th anniversary of the first definitive detection of an exoplanet orbiting a Sun-like star by Mayor and Queloz (1995). Almost 2000 exoplanets have been discovered since this breakthrough, but many fundamental questions remain open despite the enormous progress: How common are analogues of the Solar System? How do planets form and evolve? What is the relationship between stars and planets? We are observing stars that are near-perfect matches to the Sun to provide new insights into the above questions, thus exploring the planet-star connection with unprecedented precision.

  11. Evaluation of probabilistic flow in two unsaturated soils

    NASA Astrophysics Data System (ADS)

    Boateng, Samuel

    2001-11-01

    A variably saturated flow model is coupled to a first-order reliability algorithm to simulate unsaturated flow in two soils. The unsaturated soil properties are considered as uncertain variables with means, standard deviations, and marginal probability distributions. Thus, each simulation constitutes an unsaturated probability flow event. Sensitivities of the uncertain variables are estimated for each event. The unsaturated hydraulic properties of a fine-textured soil and a coarse-textured soil are used. The properties are based on the van Genuchten model. The flow domain has a recharge surface, a seepage boundary along the bottom, and a no-flow boundary along the sides. The uncertain variables are saturated water content, residual water content, van Genuchten model parameters alpha (?) and n, and saturated hydraulic conductivity. The objective is to evaluate the significance of each uncertain variable to the probabilistic flow. Under wet conditions, saturated water content and residual water content are the most significant uncertain variables in the sand. For dry conditions in the sand, however, the van Genuchten model parameters ? and n are the most significant. Model parameter n and saturated hydraulic conductivity are the most significant for the wet clay loam. Saturated water content is most significant for the dry clay loam. Résumé. Un modèle d'écoulement variable en milieu saturé est couplé à un algorithme d'exactitude de premier ordre pour simuler les écoulements en milieu non saturé dans deux sols. Les propriétés des sols non saturés sont considérés comme des variables incertaines avec des moyennes, des écarts-types et des distributions de probabilité marginale. Ainsi chaque simulation constitue un événement d'écoulement non saturé probable. La sensibilité des variables incertaines est estimée pour chaque événement. Les propriétés hydrauliques non saturées d'un sol à texture fine et d'un sol à texture grossière sont utilisées. Les propriétés sont basées sur le modèle de van Genuchten. Le domaine d'écoulement possède une surface de recharge, une limite de fuite à sa base et des limites sans écoulement sur les côtés. Les variables incertaines sont la teneur en eau à saturation, la teneur en eau résiduelle, les paramètres alpha (?) et n du modèle de van Genuchten et la conductivité hydraulique à saturation. L'objectif est d'évaluer la signification de chacune des variables incertaines dans l'écoulement probabiliste. Dans des conditions humides, la teneur en eau à saturation et la teneur en eau résiduelle sont les variables incertaines les plus significatives dans le sable. Toutefois, dans des conditions sèches dans le sable, les paramètres ? et n du modèle de van Genuchten sont les plus significatifs. Le paramètre n du modèle et la conductivité hydraulique à saturation sont les plus significatifs pour un sol argileux humide. La teneur en eau à saturation est très significative pour le sol argileux sec. Resumen. Se ha acoplado un modelo de flujo de saturación variable con un algoritmo de fiabilidad de primer orden con el fin de simular el flujo no saturado en dos tipos de suelos. Se ha tratado las propiedades del suelo no saturado como variables inciertas, a las que se asigna las medias, desviaciones estándar y distribuciones de probabilidad marginal correspondientes. Así, cada simulación constituye un evento probabilístico de flujo no saturado y la sensibilidad de las variables inciertas es estimada para cada evento. Se ha utilizado las propiedades de la conductividad hidráulica no saturada de dos suelos con dos tipos de textura - fina y gruesa - mediante el modelo de van Genuchten. El dominio de flujo está delimitado por una superficie de recarga, base de goteo y contornos laterales de flujo nulo. Las variables inciertas son el contenido de agua residual, el de saturación, los parámetros del modelo de van Genuchten (? y n) y la conductividad hidráulica saturada. El objetivo era evaluar la contribución de cada variable incierta al flujo pr

  12. Adaptive evolution of 5'HoxD genes in the origin and diversification of the cetacean flipper.

    The homeobox (Hox) genes Hoxd12 and Hoxd13 control digit patterning and limb formation in tetrapods. Both show strong expression in the limb bud during embryonic development, are highly conserved across vertebrates, and show mutations that are associated with carpal, metacarpal, and phalangeal deformities. The most dramatic evolutionary reorganization of the mammalian limb has occurred in cetaceans (whales, dolphins, and porpoises), in which the hind limbs have been lost and the forelimbs have evolved into paddle-shaped flippers. We reconstructed the phylogeny of digit patterning in mammals and inferred that digit number has changed twice in the evolution of the cetacean forelimb. First, the divergence of the early cetaceans from their even-toed relatives coincided with the reacquisition of the pentadactyl forelimb, whereas the ancestors of tetradactyl baleen whales (Mysticeti) later lost a digit again. To test whether the evolution of the cetacean forelimb is associated with positive selection or relaxation of Hoxd12 and Hoxd13, we sequenced these genes in a wide range of mammals. In Hoxd12, we found evidence of Darwinian selection associated with both episodes of cetacean forelimb reorganization. In Hoxd13, we found a novel expansion of a polyalanine tract in cetaceans compared with other mammals (17/18 residues vs. 14/15 residues, respectively), lengthening of which has previously been shown to be linked to synpolydactyly in humans and mice. Both genes also show much greater sequence variation among cetaceans than across other mammalian lineages. Our results strongly implicate 5'HoxD genes in the modulation of digit number, web forming, and the high morphological diversity of the cetacean manus. PMID:19074008

  13. Characterization of microbial community in the leachate associated with the decomposition of entombed pigs.

    Foot and mouth disease (FMD) is one of the acute infectious diseases in hoofed and even-toed mammals, including pigs, and it occurs via acute infection by Aphthovirus. When FMD is suspected, animals around the location of origin are typically slaughtered and buried. Other methods such as rendering, composting, and incineration have not been verified in practice in Korea. After the FMD incident, the regular monitoring of the microbial community is required, as microorganisms greatly modify the characteristics of the ecosystem in which they live. This is the result of their metabolic activities causing chemical changes to take place in the surrounding environment. In this study, we investigated changes in the microbial community during a 24 week period with DNA extracts from leachate, formed by the decomposition of buried pigs at a laboratory test site, using denaturing gradient gel electrophoresis (DGGE) with a genomic DNA. Our results revealed that Bacteroides coprosuis, which is common in pig excreta, and Sporanaerobacter acetigenes, which is a sulfur-reduced microbe, were continuously observed. During the early stages (0~2 weeks) of tissue decomposition, Clostridium cochlearium, Fusobacterium ulcerans, and Fusobacterium sp., which are involved in skin decomposition, were also observed. In addition, various microbes such as Turicibacter sanguinis, Clostridium haemolyticum, Bacteroides propionicifaciens, and Comamonas sp. were seen during the later stages (16~24 weeks). In particular, the number of existing microbial species gradually increased during the early stages, including the exponential phase, decreased during the middle stages, and then increased again during the later stages. Therefore, these results indicate that the decomposition of pigs continues for a long period of time and leachate is created continuously during this process. It is known that leachate can easily flow into the neighboring environment, so a long-term management plan is needed in burial locations for FMD-infected animals. PMID:23075782

    The present study describes the organization of the orexinergic (hypocretinergic) neurons in the hypothalamus of the giraffe and harbour porpoise--two members of the mammalian Order Cetartiodactyla which is comprised of the even-toed ungulates and the cetaceans as they share a monophyletic ancestry. Diencephalons from two sub-adult male giraffes and two adult male harbour porpoises were coronally sectioned and immunohistochemically stained for orexin-A. The staining revealed that the orexinergic neurons could be readily divided into two distinct neuronal types based on somal volume, area and length, these being the parvocellular and magnocellular orexin-A immunopositive (OxA+) groups. The magnocellular group could be further subdivided, on topological grounds, into three distinct clusters--a main cluster in the perifornical and lateral hypothalamus, a cluster associated with the zona incerta and a cluster associated with the optic tract. The parvocellular neurons were found in the medial hypothalamus, but could not be subdivided, rather they form a topologically amorphous cluster. The parvocellular cluster appears to be unique to the Cetartiodactyla as these neurons have not been described in other mammals to date, while the magnocellular nuclei appear to be homologous to similar nuclei described in other mammals. The overall size of both the parvocellular and magnocellular neurons (based on somal volume, area and length) were larger in the giraffe than the harbour porpoise, but the harbour porpoise had a higher number of both parvocellular and magnocellular orexinergic neurons than the giraffe despite both having a similar brain mass. The higher number of both parvocellular and magnocellular orexinergic neurons in the harbour porpoise may relate to the unusual sleep mechanisms in the cetaceans. PMID:22683547

As razões elementais Ca/Fe, Si/Fe, Mg/Fe são típicas de estrelas do halo, apontando para um processo rápido de enriquecimento, via estrelas masssivas (SN's tipo II). No entanto, este cenário não combina com os resultados derivados de nebulosas planetárias do bojo tais como os de Ratag et al.

Neste cenário, o estudo de estrelas simbióticas possibilita uma abordagem particularmente apropriada para o problema das abundâncias químicas de estrelas de massa intermediária em estágios avançados da evoluçao estelar. Apresentamos aqui os resultados da determinacão das abundâncias do grupo do CNO numa extensa amostra de simbióticas do bojo. Aliás, com a disponibilidade de espectros no visível determinamos também abundâncias de Ar, Ne, S e He, fundamentais para analisar os processos de enriquecimento químico ocorridos ao longo da evolução estelar, bem como a evolução química do meio interestelar. Com os espectros UV do satelite IUE obtivemos abundâncias de C, necessárias no estudo da evolução dos sistemas. As relaçoes C/N-O/N mostram que o material nebular é produto do vento da componente gigante e não dos eventos de nova que às vezes acontecem nestes sistemas, como foi mostrado por Nussbaumer et al (1988,A&A,198,179). As abundâncias de Ar, S, Ne e O são compativeis com resultados de fontes no disco e bojo, seguindo o gradiente proposto por muitos autores na literatura a partir de diferentes objetos como cefeidas, nebulosas planetárias e anãs G.

    Wildlife incidents with aircraft cost the United States (U.S.) civil aviation industry >US1.4 billion in estimated damages and loss of revenue from 1990 to 2009. Although terrestrial mammals represented only 2.3 % of wildlife incidents, damage to aircraft occurred in 59 % of mammal incidents. We examined mammal incidents (excluding bats) at all airports in the Federal Aviation Administration (FAA) National Wildlife Strike Database from 1990 to 2010 to characterize these incidents by airport type: Part-139 certified (certificated) and general aviation (GA). We also calculated relative hazard scores for species most frequently involved in incidents. We found certificated airports had more than twice as many incidents as GA airports. Incidents were most frequent in October ( n = 215 of 1,764 total) at certificated airports and November ( n = 111 of 741 total) at GA airports. Most (63.2 %) incidents at all airports ( n = 1,523) occurred at night but the greatest incident rate occurred at dusk (177.3 incidents/hr). More incidents with damage ( n = 1,594) occurred at GA airports (38.6 %) than certificated airports (19.0 %). Artiodactyla (even-toed ungulates) incidents incurred greatest (92.4 %) damage costs ( n = 326; US51.8 million) overall and mule deer ( Odocoileus hemionus) was the most hazardous species. Overall, relative hazard score increased with increasing log body mass. Frequency of incidents was influenced by species relative seasonal abundance and behavior. We recommend airport wildlife officials evaluate the risks mammal species pose to aircraft based on the hazard information we provide and consider prioritizing management strategies that emphasize reducing their occurrence on airport property.

  17. Comparative chromosome painting of pronghorn (Antilocapra americana) and saola (Pseudoryx nghetinhensis) karyotypes with human and dromedary camel probes

    PubMed Central

    2014-01-01

    Background Pronghorn (Antilocapridae, 2n = 58) and saola (Bovidae, 2n = 50) are members of Pecora, a highly diversified group of even-toed hoofed mammals. Karyotypes of these species were not involved in chromosome painting studies despite their intriguing phylogenetic positions in Pecora. Results To trace the chromosome evolution during very fast radiation of main families from the common Pecoran ancestor, high-resolution comparative chromosome maps of pronghorn and saola with human (HSA) and dromedary camel (CDR) painting probes were established. The human and dromedary camel painting probes revealed 50 and 64 conserved segments respectively in the pronghorn genome, while 51 and 63 conserved segments respectively in the saola genome. Integrative analysis with published comparative maps showed that inversions in chromosomes homologous to CDR19/35/19 (HSA 10/20/10), CDR12/34/12 (HSA12/22/12/22), CDR10/33/10 (HSA 11) are present in representatives of all five living Pecoran families. The pronghorn karyotype could have formed from a putative 2n = 58 Pecoran ancestral karyotype by one fission and one fusion and that the saola karyotype differs from the presumed 2n = 60 bovid ancestral karyotype (2n = 60) by five fusions. Conclusion The establishment of high-resolution comparative maps for pronghorn and saola has shed some new insights into the putative ancestral karyotype, chromosomal evolution and phylogenic relationships in Pecora. No cytogenetic signature rearrangements were found that could unite the Antilocapridae with Giraffidae or with any other Pecoran families. Our data on the saola support a separate position of Pseudorigyna subtribe rather than its affinity to either Bovina or Bubalina, but the saola phylogenetic position within Bovidae remains unresolved.

    O método Grade of Membership (GoM) tem sido cada vez mais utilizado por demógrafos brasileiros e tem a vantagem de possuir um parâmetro que mensura a heterogeneidade individual, com base nas correlações não-observáveis entre as categorias de resposta das variáveis de interesse, gerando um medida do grau de pertencimento de cada indivíduo a perfis extremos. Alguns autores, contudo, chamam atenção para questões importantes na calibragem dos modelos finais que utilizam o programa GoM versão 3.4, como o problema de identificabilidade – soluções múltiplas para parâmetros estimados. Neste artigo, é sugerido um procedimento capaz de identificar um modelo final com solução única que descreva os tipos puros mais fidedignos à base de dados, em uma tentativa de otimização. Para ilustrar esse processo, utilizou-se uma base de dados correspondente a um levantamento econômico e sociodemográfico de uma população de pequenos agricultores residentes ao longo da Rodovia Transamazônica, no Estado do Pará. Também identificou-se a existência de instabilidade nos parâmetros estimados pelo programa GoM 3.4, sendo proposto um método de estabilização de seus valores. Com esses procedimentos combinados, os usuários do programa GoM 3.4 poderão descrever sua base de dados de forma mais adequada e responder às críticas sobre questões de identificabilidade e estabilidade dos modelos resultantes. Essas soluções empíricas são relevantes por afetarem cálculos de prevalência e de incidência de eventos de interesse, além de trazerem consequências importantes sobre o ponto e o momento corretos para intervenções de políticas públicas ou de planejamento prospectivo em análises de projeção.

    Growing morphological and molecular evidence indicates that the porpoises, dolphins, and whales evolved within the even-toed ungulates, formerly known as Artiodactyla. These animals are now grouped in the Cetartiodactyla. We evaluated the antigenic similarity of the immunoglobulin G (IgG) molecules of 15 cetacean species and the domestic cow. The similarity was scored using three distinct antibodies raised against bottlenose dolphin (Tursiops truncatus) IgG in a Western blot, an indirect enzyme-linked immunosorbent assay (ELISA), and a competitive ELISA format. A score was generated for the genetic distance between each species and T. truncatus using the cytochrome b sequence. Each antibody displayed a distinct pattern of reactivity with the IgG antibodies of the various species. The monoclonal antibody (MAb) specific for the gamma heavy chain of T. truncatus was reactive with all monodontids, delphinids, and phocoenids. The light-chain-specific MAb reacted with IgG of delphinoid and phocoenid species and one of the two mysticete species tested. The polyclonal antibody was broadly cross-reactive across all cetaceans and the domestic cow. Using the MAb specific for the gamma heavy chain, the degree of IgG cross-reactivity ranged from less than 17% for the mysticetes to 106% for killer whale Orcinus orca. The IgG in beaked whale and baleen whale sera was significantly less cross-reactive with bottlenose dolphin IgG than sera from other toothed whales. A strong negative correlation was demonstrated between antigenic cross-reactivity of IgG molecules and the genetic distance of their hosts. The data generated will be useful for the development of clinical serodiagnostics in diverse cetacean species. PMID:18768672

    Wildlife incidents with aircraft cost the United States (U.S.) civil aviation industry >US$1.4 billion in estimated damages and loss of revenue from 1990 to 2009. Although terrestrial mammals represented only 2.3 % of wildlife incidents, damage to aircraft occurred in 59 % of mammal incidents. We examined mammal incidents (excluding bats) at all airports in the Federal Aviation Administration (FAA) National Wildlife Strike Database from 1990 to 2010 to characterize these incidents by airport type: Part-139 certified (certificated) and general aviation (GA). We also calculated relative hazard scores for species most frequently involved in incidents. We found certificated airports had more than twice as many incidents as GA airports. Incidents were most frequent in October (n = 215 of 1,764 total) at certificated airports and November (n = 111 of 741 total) at GA airports. Most (63.2 %) incidents at all airports (n = 1,523) occurred at night but the greatest incident rate occurred at dusk (177.3 incidents/hr). More incidents with damage (n = 1,594) occurred at GA airports (38.6 %) than certificated airports (19.0 %). Artiodactyla (even-toed ungulates) incidents incurred greatest (92.4 %) damage costs (n = 326; US$51.8 million) overall and mule deer (Odocoileus hemionus) was the most hazardous species. Overall, relative hazard score increased with increasing log body mass. Frequency of incidents was influenced by species relative seasonal abundance and behavior. We recommend airport wildlife officials evaluate the risks mammal species pose to aircraft based on the hazard information we provide and consider prioritizing management strategies that emphasize reducing their occurrence on airport property.

  1. Ondas de choque em jatos de quasares e objetos BL Lacertae

    Este trabalho é parte de um projeto que vem sendo realizado há dois anos no CRAAM, cujos objetivos principais são analisar e aplicar um modelo generalizado de ondas de choque em jatos relativísticos de plasma, presentes em quasares e objetos BL Lacertae, para explicar a variabilidade observada nestes objetos. O método consiste em uma decomposição de curvas de luz em séries de explosões similares, em várias freqüências, baseando-se em uma evolução espectro-temporal média das explosões. A partir da evolução média, um ajuste de cada explosão é feito com base em equações empíricas, modificando-se apenas parâmetros específicos de cada explosão. Inicialmente o modelo foi aplicado ajustando-se as curvas de luz a explosões delineadas por uma evolução do choque em três estágios, segundo a predominância do processo de emissão: síncrotron, Compton e adiabático. Entretanto, nesta nova fase de projeto, visando uma parametrização mais concisa, uma otimização do algoritmo de ajuste e uma convergência mais rápida, a formulação para cada evento foi assumida com uma evolução em apenas dois estágios: subida e descida. Isto possibilitou uma ótima delineação das curvas de luz das fontes OV236, OJ287, 3C273 e BL Lac, entre 1980 e 2000, nas freqüências 4.8, 8.0, 14.5 e 22 GHz, utilizando-se dados do Observatório da Universidade de Michigan, do Observatório do Itapetinga (Atibaia SP) e do Observatório Metsähovi. Como conclusões importantes, verificou-se que: os parâmetros ajustados descrevem o comportamento do jato; os valores do índice que descreve a expansão do jato sugerem que o mesmo se expande de uma forma não-cônica; o campo magnético é turbulento atrás da frente de choque; e as peculiaridades das explosões são devidas à influência de grandezas tais como o coeficiente da distribuição espectral de energia dos elétrons, a intensidade de campo magnético e o fator de feixe Doppler, no início do choque.

    Discutimos nossa participação em um curso de treinamento para professores de diversas disciplinas do ensino médio. Nossa preocupação básica foi desenvolver instrumentos educacionais adequados para levar à sala de aula, nesse nível de ensino, de forma contextualizada, questionamentos freqüentes dos alunos sobre astronomia e sua relação com tecnologia e sociedade. Encaminhamos questões como: a evolução da astronomia, suas relações com outros ramos do conhecimento humano e conseqüentes aplicações; avanços na tecnologia dos instrumentos ópticos versus a importância da observação do céu a olho nu; a relação entre olho humano, luneta e telescópio; e desenvolvimento da tecnologia espacial e sua influência em nosso cotidiano. Objetivamos com isto fazer um resgate histórico e pedagógico das aplicações e observações do céu no cenário escolar, destacando a relação entre eventos astronômicos, olho humano, instrumentos mediadores e suas contextualizações históricas e sociais. Produtos desta abordagem foram o desenvolvimento e a adaptação de práticas e materiais instrucionais diversos (e.g., "espelhos" de isopor e "raios luminosos" de bolinhas de gude; montagens envolvendo velas, lasers, lentes e espelhos; desmonte e análise de peças de um telescópio; etc.). Além disto, como outro resultado deste trabalho, elaboramos textos sobre história da astronomia e da óptica para atividades em classe. Com estas ações visamos facilitar a concretização de conceitos físicos envolvidos, exemplificar um ensino contextualizado e interdisciplinar motivado por temas astronômicos e favorecer que práticas e discussões feitas com os treinandos possam ser transpostas para a sala de aula. A reação dos professores às práticas propostas foi bastante positiva. Todos esses aspectos são discutidos em detalhe neste trabalho. (PPGECNM/UFRN; PRONEX/FINEP; NUPA/USP; Temáticos/FAPESP)

  3. A comparison of postnatal arterial patterns in a growth series of giraffe (Artiodactyla: Giraffa camelopardalis)

    Nearly all living artiodactyls (even-toed ungulates) possess a derived cranial arterial pattern that is highly distinctive from most other mammals. Foremost among a suite of atypical arterial configurations is the functional and anatomical replacement of the internal carotid artery with an extensive, subdural arterial meshwork called the carotid rete. This interdigitating network branches from the maxillary artery and is housed within the cavernous venous sinus. As the cavernous sinus receives cooled blood draining from the nasal mucosa, heat rapidly dissipates across the high surface area of the rete to be carried away from the brain by the venous system. This combination yields one of the most effective mechanisms of selective brain cooling. Although arterial development begins from the same embryonic scaffolding typical of mammals, possession of a rete is typically accompanied by obliteration of the internal carotid artery. Among taxa with available ontogenetic data, the point at which the internal carotid obliterates is variable throughout development. In small-bodied artiodactyls, the internal carotid typically obliterates prior to parturition, but in larger species, the vessel may remain patent for several years. In this study, we use digital anatomical data collection methods to describe the cranial arterial patterns for a growth series of giraffe (Giraffa camelopardalis), from parturition to senescence. Giraffes, in particular, have unique cardiovascular demands and adaptations owing to their exceptional body form and may not adhere to previously documented stages of cranial arterial development. We find the carotid arterial system to be conserved between developmental stages and that obliteration of the giraffe internal carotid artery occurs prior to parturition. PMID:26925324

    The present study describes the organization of the orexinergic (hypocretinergic) neurons in the hypothalamus of the giraffe and harbour porpoise – two members of the mammalian Order Cetartiodactyla which is comprised of the even-toed ungulates and the cetaceans as they share a monophyletic ancestry. Diencephalons from two sub-adult male giraffes and two adult male harbour porpoises were coronally sectioned and immunohistochemically stained for orexin-A. The staining revealed that the orexinergic neurons could be readily divided into two distinct neuronal types based on somal volume, area and length, these being the parvocellular and magnocellular orexin-A immunopositive (OxA+) groups. The magnocellular group could be further subdivided, on topological grounds, into three distinct clusters – a main cluster in the perifornical and lateral hypothalamus, a cluster associated with the zona incerta and a cluster associated with the optic tract. The parvocellular neurons were found in the medial hypothalamus, but could not be subdivided, rather they form a topologically amorphous cluster. The parvocellular cluster appears to be unique to the Cetartiodactyla as these neurons have not been described in other mammals to date, while the magnocellular nuclei appear to be homologous to similar nuclei described in other mammals. The overall size of both the parvocellular and magnocellular neurons (based on somal volume, area and length) were larger in the giraffe than the harbour porpoise, but the harbour porpoise had a higher number of both parvocellular and magnocellular orexinergic neurons than the giraffe despite both having a similar brain mass. The higher number of both parvocellular and magnocellular orexinergic neurons in the harbour porpoise may relate to the unusual sleep mechanisms in the cetaceans. PMID:22683547

    Foot-and-mouth disease virus (FMDV) causes a highly contagious viral disease of even-toed ungulates and is one of the most important economic diseases of livestock. Most studies of FMDV are done in countries where control measures are being implemented. In contrast, in areas such as sub-Saharan Africa, where FMDV is endemic and new strains are likely to emerge, there are only sporadic submissions to the World Reference Laboratory, Pirbright, United Kingdom. This paper describes the molecular epidemiology of FMDV in the Adamawa province of Cameroon based on a population sample of cattle herds. Serotypes SAT2 and A were isolated in the cross-sectional study. SAT2 isolates were all similar, with phylogenetic distances of <6%, and were most closely related to published sequences of isolates from Eritrea and Saudi Arabia. Serotype A isolates were more variable, with phylogenetic distances of 0 to 11%, and were most closely related to historic isolates from Cameroon. Use of a population-based sample gives a representative sample of virus diversity and will improve our understanding of the evolution of FMDV and its epidemiology. A supplementary study of pigs passing through the railhead collection yard at Ngaoundere detected a serotype O virus. A third pilot longitudinal study monitored viral persistence in three cattle herds over 12 months, and serotype O and A viruses were recovered from a herd 12 months after it was first recorded as being infected with SAT2 virus. The pig type O isolate was not closely related to that recovered from the cattle, suggesting that the pigs had not introduced the O virus into the cattle herds. PMID:15131187

    Este artículo documenta una respuesta agregada negativa del logro educativo superior (más de 12 años de escolaridad) en México a la recesión de 1982–83 y el estancamiento que le siguió. La respuesta no fue homogénea entre géneros, regiones y entornos familiares. Los hombres experimentaron una caída en el logro mientras que las mujeres experimentaron un crecimiento más lento. En promedio, los estados con un mayor logro antes del choque experimentaron mayores caídas. La respuesta entre distintos entornos familiares no presenta un patrón claro. Sin embargo, el efecto negativo en el logro se observa incluso entre hermanos. La evidencia sugiere una historia por el lado de la demanda: la caída en el ingreso de los hogares parece ser el determinante de la caída/desaceleración del logro educativo superior. La conclusión es que la recesión y la falta de crecimiento que le siguió tuvieron un efecto negativo importante y duradero en la formación de capacidades en México. PMID:25328251

    Introducción y desarrollo En los próximos 50 años vamos a presenciar un incremento significativo de la población mayor de 65 años y por lo tanto va a aumentar, considerablemente, el número de individuos con riesgo de desarrollar demencias neurodegenerativas, especialmente la enfermedad de Alzheimer (EA). Las estrategias actuales de tratamiento farmacológico y no farmacológico se han centrado en las fases sintomáticas de esta enfermedad y, gradualmente, vamos teniendo una mayor comprensión de los posibles factores de riesgo del síndrome clínico. Conclusiones Los estudios de neuroimagen han sido muy útiles para mostrar los cambios estructurales del envejecimiento normal y patológico, así como también los factores de riesgo para la EA. Los tratamientos apropiados de los factores de riesgo y su posible combinación con tratamientos específicos para la EA podrían prolongar el período presintomático de la EA y, por tanto, mejorar la calidad de vida y disminuir la carga para el paciente, la familia y la sociedad.

    Introducción: La anastomosis hipogloso-facial es la técnica de elección para la reparación de la parálisis facial cuando no se dispone de un cabo proximal sano del nervio facial. La técnica de anastomosis mediante fresado mastoideo y sección parcial del hipogloso minimiza la atrofia lingual sin sacrificar resultados a nivel facial. Método: La porción mastoidea del nervio facial transcurre por la pared anterior de la AM, a un promedio de 18+/-3 mm de profundidad respecto de la pared lateral. Se debe reconocer la cresta supramastoidea, desde la cual se marca una línea vertical paralela al eje mayor de la AM, 1 cm por detrás de la pared posterior del CAE El fresado se comienza desde la línea medio mastoidea hasta la pared posterior del CAE. Una vez encontrado el nervio facial en el tercio medio del canal mastoideo, el mismo es seguido hacia proximal y distal. Resultados: El abordaje descripto permite acceder al nervio facial intratemporal en su porción mastoidea, y efectuar un fresado óseo sin poner en riesgo al nervio o a estructuras vasculares cercanas. Se trata de un procedimiento técnicamente más sencillo que los abordajes amplios habitualmente utilizados al hueso temporal; no obstante su uso debe ser restringido mayormente a la anastomosis hipogloso-facial. Conclusión: Esta es una técnica relativamente sencilla, que puede ser reproducida por cirujanos sin mayor experiencia en el tema, luego de su paso por el laboratorio de anatomía. PMID:23596555

    2015-01-01

    We examine shear velocity anisotropy in the Yuha Desert, California using aftershocks of the 2010 M7.2 El Mayor-Cucapah earthquake. The Yuha Desert is underlain by a complex network of right- and left-lateral conjugate faults, some of which experienced triggered slip during the El Mayor-Cucapah earthquake. An automated method that implements multiple measurement windows and a range of bandpass filters is used to estimate the fast direction (?) and delay time (?t) of the split shear waves. We find an average ? oriented approximately north–south suggesting it is primarily controlled by the regional maximum compressive stress direction. However, the spatial variability in ? reveals that the fault structures that underlie the Yuha Desert also influence the measured splitting parameters. We infer that the northeast- and northwest-oriented ? reflect shear fabric subparallel to the conjugate fault structures. We do not observe a simple correlation between ?t and hypocentral distance. Instead, the observed spatial variation in ?t suggests that near-source variation in anisotropic strength may be equal to or more important than effects local to the station. No temporal variation in splitting parameters is observed during the 70-day period following the main shock. In this region of complex faulting, we observe a spatially variable pattern of anisotropy that is both stress- and structure-controlled. This study suggests that shear fabric can form even along short, discontinuous fault strands with minimal offset.

    A sample of 323 residents of New Jersey stratified by neighborhood quality (excellent, good, fair, poor) was gathered to determine if trust in science and technology to protect public health and environment at the societal scale was associated with trust of the local officials, such as the mayor, health officer, developers, mass media, and legislators who are guardians of the local environment. Societal (trust of science and technology) and neighborhood (mayor, health officer) dimensions of trust were found. These societal and neighborhood trust dimensions were weakly correlated. Respondents were divided into four trust-of-authority groups: high societal-high neighborhood, low societal-low neighborhood, high societal-low neighborhood, and low societal-high neighborhood. High societal-high neighborhood trust respondents were older, had lived in the neighborhoods for many years, were not troubled much by neighborhood or societal environmental threats, and had a strong sense of control over their environment. In strong contrast, low societal-low neighborhood trust respondents were relatively young, typically had lived in their present neighborhood for a short time, were troubled by numerous neighborhood and societal environmental threats, did not practice many personal public health practices, and felt little control over their environment.

    Kapitza-Dirac-Talbot-Lau interferometry (KDTLI) has recently been established as an ideal method to perform quantum matter wave experiments with large, highly polarizable molecules in an unprecedented mass range of beyond 1000 atomic mass units [1]. Since the interference visibility reveals important information on the properties of the examined particles, such as their mass and polarizability, we identified KDTLI as a valuable tool for precision metrology. We demonstrate that quantum interferometry can therefore also serve as a powerful complement to mass spectrometry [2], in particular in cases where fragmentation may occur in the detector. Our new method is applicable to a wide range of molecules and is particularly valuable for characterizing neutral molecular beams. [1] S. Gerlich, L. Hackerm"uller, K. Hornberger, A. Stibor, H.

    Hace ya más de 30 años en Volcano Ranch, EE.UU., un extenso chubasco cósmico (ECC) fue detectado con energía en exceso de 1020 eV. Desde entonces, observatorios ubicados en Haverah Park del Reino Unido, Yakutsk de Rusia, AGASA de Japón y Dugway de EE.UU. también han observado ECC con energías mayores que 1020 eV. Poco se sabe de dichos rayos, y en particular cuál es la naturaleza del primario, de dónde provienen, y cómo son acelerados, pero su naturaleza ultrarelativista excluye la mayoría de las respuestas dejando sólo algunas plausibles de ser investigadas experimentalmente. Grupos de científicos de 20 países están trabajando con el fin de construir dos arreglos de detectores gigantes, uno en cada hemisferio a lo largo de 3000 km2 c/u. Dichas dimensiones son necesarias debido al flujo estimado de 1 rayo cósmico/centuria/km2/sr. La sede del Observatorio del Sur es la Argentina. El proyecto fue nombrado Pierre Auger en conmemoración del célebre físico francés que detectó por primera vez chubascos cósmicos en 1938. El proyecto focaliza su interés en rayos cósmicos con energías mayores que 1020 eV.

  15. Moral Combat in An Enemy of the People: Public Health versus Private Interests

    2010-01-01

    Dr Thomas Stockmann, the protagonist of Ibsen's play, An Enemy of the People, discovers a serious health threat in the Baths of his Norwegian town. The Baths have been marketed as a health resort to lure visitors. Dr Stockmann alerts officials about the problem and assumes that they will close the Baths until it is corrected. He is met with fierce resistance, however. His brother, the town's mayor, favors keeping the Baths open and correcting the problem gradually. He advances multiple arguments that appeal to the economic interests of the town and Thomas's role-related obligation as a citizen. His wife, Katherine, wants him to cooperate with the mayor. She marshals several arguments that appeal to his obligations as a father. This paper reconstructs and examines the competing arguments, shows how Ibsen's play has both contemporary relevance and moral depth, and demonstrates how Dr Stockmann's responses can be interpreted as an argument that complying with his duties to protect the public health do not force him to renege on his core commitments as a parent and as a citizen.

    Presentamos imágenes CCD en los filtros BVI y H? de una muestra de 10 galaxias Seyfert 1 y Narrow Line Seyfert 1. Recientes observaciones muestran que hay una diferencia significante en el índice espectral óptico entre NLS1s y Sy1 normales, siendo para las primeras del orden de 2. Otra característica importante es que la mayor parte de las NLS1s muestran tasas de FeII/H? mayores que las observadas en otras Sy1s. Desde el punto de vista fotométrico, estas galaxias no tienenningún tipo de estudio previo. Presentamos magnitudes totales, perfiles de luminosidad y mapas de color junto con un detallado análisis de la formación estelar en estos objetos. Encontramos que la descomposición en bulbo + disco representa adecuadamente los perfiles de luminosidad de las galaxias de la muestra. Sin embargo, en todos los casos es necesario que el disco tenga un agujero en su centro. El radio de este agujero va desde los 3 a los 9 kpc. Si bien no tenemos aún una explicación para este hecho, los agujeros parecen estar asociados a anillos circumnucleares de alto oscurecimiento E(B-V) ~1. Los perfiles presentan también un fuerte gradiente de color, siendo notablemente más azules hacia la región nuclear. Los objetos de la muestra cubren todo el rango de tipos morfológicos, no obstante, no encontramos regiones de formación estelar en las regiones exteriores de las galaxias. La formación estelar está confinada a la región nuclear y se data en alrededor de 5 x 107 años.

    Resumen Este artículo compara los resultados económicos entre los inmigrantes latinoamericanos en España y Estados Unidos. Detectamos un efecto de selección por el que la mayoría de los inmigrantes latinoamericanos en España proceden de Sudamérica de un entorno de clases medias, mientras la mayoría de los inmigrantes que van a los Estados Unidos son centroamericanos de clase baja. Este efecto de selección explica las diferencias transnacionales en la probabilidad de empleo, logro ocupacional y salarios obtenidos. A pesar de las diferencias en los orígenes y las características de los latinoamericanos en ambos países, los factores demográficos, humanos y de capital social parecen operar de forma similar en ambos países; y cuando los modelos se estiman separadamente por estatus legal, descubrimos que los efectos se acentúan más entre los inmigrantes irregulares cuando se los compara con los regulares, especialmente en Estados Unidos.

    Two teachers from the town of San Pedro de Atacama, in the northern desert of the South American nation of Chile, arrive in Magdalena, New Mexico, Sunday, January 28, for a two-week visit that is part of a Sister Cities program sponsored by Associated Universities, Inc. (AUI), the nonprofit research corporation that operates the National Radio Astronomy Observatory (NRAO). They will be accompanied by their town's mayor. Myriam Nancy Rivera Mercado, Head of the high school in San Pedro, Gabriela Fernanda Rodriguez Moraleda, a tourism teacher there, and San Pedro Mayor Sandra Berna Martinez will begin a visit that includes classroom observations in the Magdalena schools, a reception hosted by the Magdalena Village Council, and a Mayor's Breakfast with Magdalena Mayor Jim Wolfe. They also will meet local residents, tour the Bosque del Apache National Wildlife Refuge with a second-grade class, visit an area ranch, tour the Very Large Array (VLA) radio telescope, and see Socorro's Community Arts Party. "These teachers will learn much about New Mexico, the United States, and our educational system, and will take this new knowledge back to their students and their community," said NRAO Education Officer Robyn Harrison. The visit is part of a Sister Cities program initiated and funded by AUI, which operates the NRAO for the U.S. National Science Foundation. Radio astronomy is a common link between San Pedro de Atacama and Magdalena. San Pedro is near the site of the Atacama Large Millimeter/submillimeter Array (ALMA), an international telescope project now under construction with funding by major partners in North America, Europe, and Japan. Magdalena is near the site of NRAO's VLA radio telescope. In Magdalena, the Village Council and Mayor Wolfe formalized their participation in the Sister Cities program last September, and San Pedro ratified the program in December. In San Pedro, the ceremony ratifying the agreement was attended by U.S. Ambassador to Chile Craig K. Kelly. The Chilean teachers are visiting Magdalena while they are on their Southern Hemisphere summer vacation, and Magdalena's schools are in session. Two Magdalena teachers, Joleen Welborn and Sandra Montoya, will visit San Pedro in June, while they are on summer vacation and the Chilean schools will be in session. Dr. Eduardo Hardy, the AUI/NRAO representative in Chile, will accompany the Chilean teachers on their visit, which has been coordinated by Harrison. "ALMA is a groundbreaking example of the type of international cooperation that marks the future of astronomy. We are especially pleased to sponsor a program that brings together two communities that both enjoy proximity to world-class astronomical research facilities," said Dr. Fred K.Y. Lo, NRAO Director. "While separated by many miles, San Pedro de Atacama and Magdalena have much in common. Both are small communities in high desert environments, and both are next to telescopes where the world's astronomers will be making many exciting discoveries in the coming decades. Bringing these two communities together will advance education and international understanding," Harrison said. The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.

    In August 2000, a survey of public opinion was carried out among visitors, local residents and representatives of local self-governments in the territory of the Podyji/Thaya River Basin National Park in the Czech Republic. The goal was to obtain stakeholders' opinions and attitudes towards nature conservation, the National Park and tourism within the territory which used to be closed to the public for 40 years due to the Iron Curtain. Without the knowledge of opinions of stakeholders it is not possible to manage nature conservation and development in the protected area properly. Using the method of direct interviews, 646 questionnaires where collected, of which 523 were from visitors and tourists, 115 from local residents and 8 from mayors of towns/villages. The questionnaires were analysed in order to detect differences in attitudes among the respondent groups in the following thematic areas: (a) the National Park, its environment and perception of it by respondents; (b) relationship of respondents to the territory; (c) tourism and attitudes towards recreational activities; (d) the Administration of the National Park and evaluation of its work; and (e) economic impact of tourism for local communities. One section of the study focused on comparing the attitudes between local inhabitants and mayors and the other section presents a collation of opinions from locals, mayors and tourists. Although a positive evaluation of the national park dominated the results, some negative attitudes and experiences were identified among locals. In addition, the situation also differed within communities. Results also indicated a relatively strong relationship to the territory by locals, but low job opportunities and income from tourism. The level of tourism intensity was perceived as an increasing and sometimes disturbing factor for local communities; motoring was observed as being the most negative activity for nature. The Administration of the Podyji/Thaya River Basin National Park was sometimes criticised and the communication with the community was not always evaluated satisfactorily. All groups of respondents identified waste management to be the most pressing issue. Identification of differences in attitudes of interviewed respondents may be effectively used in planning environmental management and sustainable tourism development in the area. PMID:16549229
