Magda Mateus Cardenas, director of Centro Amauta, Cusco, Peru: interview.  

PubMed

Magda Mateus Cardenas, trained as an anthropologist, is currently director of Centro Amauta, a feminist organization in Peru that addresses issues of gender, class, and culture. In this interview, Mateus Cardenas describes her long involvement with development organizations and grass-roots campaigns to improve women's status. She notes that, although many organizations have adopted a gender perspective, few comprehend its highly political, transformational aspects. Women's rights tend to be viewed by development agencies as just one more factor to be incorporated into development projects rather than as a perspective that changes views of development itself. A genuine gender perspective entails changes in the organizational, social, and political aspects of the themes of autonomy and empowerment, with adaptations of content and methods to local conditions. A precondition to women's emancipation is access to and control of financial and economic resources. This, in turn, requires training in technical skills and access to the marketplace on more competitive terms. PMID:12320745

Medicina integrativa en Am?rica: De qu? forma se est? practicando la medicina integrativa en los centros cl?nicos en los Estados Unidos  

PubMed Central

RESUMEN EJECUTIVO El impulso para desarrollar e implementar estrategias de medicina integrativa está enraizado en el deseo de mejorar la atención al paciente. The Bravewell Collaborative, una organización sin ánimo de lucro dedicada a la mejora de la atención sanitaria, define la medicina integrativa como “un enfoque de la medicina que coloca al paciente en el centro y se dirige al conjunto completo de influencias físicas, emocionales, mentales, sociales, espirituales y ambientales que afectan a la salud de la persona. Con una estrategia personalizada que considera las condiciones, necesidades y circunstancias únicas del paciente, utiliza las intervenciones más apropiadas de una variedad de disciplinas científicas para curar la afección y la enfermedad y ayudar a las personas a recobrar y mantener una salud óptima”. En las pasadas dos décadas, se ha documentado un número creciente de centros clínicos que proporcionan medicina integrativa, el número de facultades y escuelas médicas que enseñan estrategias integrativas, el número de investigadores que estudian intervenciones integrativas, y el número de pacientes que solicitan cuidados integrativos. Pero se desconocía si la medicina integrativa se estaba ofreciendo de manera igual, similar, o dispar. Además, mientras que los estudios anteriores se centraban en la prevalencia y el uso de la medicina complementaria o alternativa (MCA) por parte de los pacientes1,2 o de los médicos en hospitales3, enumerando la utilización de terapias MCA individuales, se había recogido muy poca información con respecto a la práctica real de la medicina integrativa que, por definición, trata a la persona en su conjunto. En 2011, The Bravewell Collaborative encargó una encuesta para determinar la forma en que la medicina integrativa se estaba practicando en los Estados Unidos: (1) describiendo las poblaciones de pacientes y las afecciones sanitarias tratadas más habitualmente; (2) definiendo las prácticas y modelos fundamentales de atención; (3) determinando cómo se reembolsaban los servicios; (4) identificando los valores y los principios subyacentes a la atención; y (5) determinando los factores principales que impulsan una implementación satisfactoria.

Incidence of neoplastic donors in Organizzazione Centro Sud Trapianti area during the 2003-2005 period.  

PubMed

The aim of this study is to evaluate the incidence of malignant tumors in cadaver donors and the possibility of neoplastic disease transmission to the recipients in the Organizzazione Centro Sud Trapianti (OCST) area. Among 1744 potential donors identified from 2003 to 2005, 125 (7.1%) showed an elevated malignant neoplastic risk. In 2003 a malignant tumor was diagnosed in 60 donors of mean age 59.6 +/- 19.9 years (median 62.5, M:36 F:24); in 2004, 33 donors of mean age, 61.4 +/- 15.9 years (median 63, M:19 F:14); in 2005, 32 donors of mean age of 62.8 +/- 15.5 years (median 65.5, M:20 F:12). Prostatic cancer was the most common tumor (23.2%). In 101 of 125 cases (80.8%) the tumor was diagnosed before organ retrieval, in 23 (18.4%) cases, during the donor operation but before the transplant, and in one case (0.8%) after transplantation. Each tumor was evaluated according to the histologic types and grades. From 12 of those donors with neoplasia, 24 organs were retrieved (10 livers, 11 kidneys, 3 hearts) transplanted in 23 recipients (one liver-kidney combined transplant). Three recipients died during the perisurgical period due to causes unrelated to the tumor and therefore were not considered in the follow-up evaluation. Among the remaining nine recipients who had a mean follow-up of 38.83 months (range 9-42), no donor-transmitted disease has become apparent by imaging control. A careful donor evaluation including histologic grading and strict application of Centro Nazionale Trapianti guidelines allowed us to use donors with malignant tumors in selected cases with an apparently reduced risk of transmitted neoplastic disease.

EXAFS Study of Co/Mo Multilayers.  

NASA Astrophysics Data System (ADS)

The reduction of the measured moment in magnetic multilayers relative to the bulk value is a poorly understood phenomenon. This lack of understanding is clearly illustrated by two studies on Co/Mo where the reduced moment is attributed to two very different mechanisms. Sato reports a ``dead layer'', i.e., Co atoms near the Mo layers have no moment or a reduced moment(Noboru Sato, J. Appl. Phys. 63), 3476 (1988), while Wang, et al. report the presence of a non-magnetic compound--Co_7Mo_6.(Y. Wang, et al., J. Mag. Mag. Mater 102), 121 (1991). These studies report different saturation magnetizations for thicker Co layers; however, they agree that crystalline order vanishes as both layer thicknesses decrease and that magnetism decreases greatly for thinner Co layers. We have done structural and magnetic studies(C.L. Foiles, et al., MRS Symposium Proc. 384) (in press) on dc magnetron sputtered Co/Mo multilayers and find that the most striking feature is how the saturation magnetization scales with the apparent coordination number using EXAFS data with a Co standard. Data from the various studies will be compared.

Shallow shear wave velocity and Q structures at the El Centro strong motion accelerograph array  

NASA Astrophysics Data System (ADS)

At three sites in the U.S. Geological Survey El Centro Strong Motion Accelerograph Array (EO5, EO6 and EO7), we have used the dispersive and attenuative properties of artificially generated Rayleigh waves to infer the depth dependence of shear wave velocity (?) and quality factor (Q) and a site dependent equivalent elastic source spectrum. This approach provides an inexpensive means for determining two important quantities (? and Q) required to estimate the response of sites to earthquakes. We find that the shear velocities and the gradients in shear velocities down to depths of 100 meters at station EO6 (in the wedge between the Imperial and Brawley faults) are nearly twice those at either station EO5 and EO7 (east and west, respectively, of the wedge). Also, the seismogram character, surface wave dispersion and shear wave velocity structure at stations EO5 and EO7 are similar to each other while they are different from EO6. These results show significant structural differences between the wedge beneath EO6 and surrounding areas. The anomalously high accelerations recorded at EO6 during the 1979 Imperial Valley earthquake may be related to these differences.

Deaths on board ships assisted by the Centro Internazionale Radio Medico in the last 25 years.  

PubMed

Data on occupational diseases of seafarers and of causes of death during their career are sparse. The causes of deaths on board ships assisted by Centro Internazionale Radio Medico (CIRM), the Italian Telemedical Maritime Assistance Service (TMAS) were reviewed by examining 29,146 files of patients treated from 1986 to 2010. In the 25 years, 383 deaths occurred (1.31%). Diseases of the circulation were the most frequent, followed by external causes such as accidents and violence, infectious and parasitic diseases, alcohol and drug addiction, respiratory system diseases. Cardiovascular and external causes were the principal causes of deaths among seafarers. This investigation is the first study on the causes of death on board ships obtained from data of a maritime telemedical centre, that has assisted seafarers when they were alive or immediately after their death. The fact that diseases of the circulatory system are the first cause of death of sailing seafarers deserves specific initiatives. They should include campaigns for adequate lifestyles and the availability on ships of medical devices useful for diagnostic purposes, resuscitation as well as for verification of death.

Design of a Heliostat for Centro de Investigaciones de Astronomía (CIDA)  

NASA Astrophysics Data System (ADS)

This paper explains the procedure used in the design of a heliostat to be installed at the headquarters of the Centro de Investigaciones de Astronomía, located in the city of Mérida, Venezuela. The heliostat will be used mainly for educational and public outreach programs, so the design specifications did not require compensation for rotation of the Sun's image at the focal point. The engineering computational tools CAD-CAE were used in order to allow a seamless interaction between the two disciplines involved, Mechanical Engineering and Astronomy. It has also been taken into consideration, as a starting requirement, that all materials be easily available and that all parts, excluding the optics, could be manufactured with the equipment available at the CIDA workshop. These considerations were intended to reduce the cost of the device and to increase the feasibility of construction with limited technological facilities and financial resources. The results obtained by means of the computing tools used were validated through comparison against the analytical calculations. As a result, a robust but low cost heliostat was designed which in the near future will be used to project the Sun's image on a screen for public viewing and student research projects.

Management of Lake Como: a multiobjective analysis  

SciTech Connect

This paper describes a heuristic approach for improving the performance of multipurpose reservoirs that have already been in operation for a certain number of years. The main characteristic of the method is that the analyst must first learn from the past experience of the manager and synthesize it into a simple operating rule. Then, the analyst must point out, with the help of the manager, what the acceptable modifications of such a rule are. After this has been accomplished, the optimal improvements of the operating rule can be obtained by using standard optimization techniques. Quite satisfactory results have been obtained by applying this approach to Lake Como (Northern Italy), which has been regulated since the end of World War II. In fact, the method shows that both flood protection on the lake shores and water supply to the downstream agricultural areas can be substantially improved, without lowering the mean yearly electricity production of the downstream run-of-river plants. For this reason the operating rule proposed by the method has been programmed on a microcomputer, which is now used every day by the manager as an essential support for his final decision. This and the fact that other actions suggested by this analysis have indeed been undertaken by the local authorities gave to this study the chance to have a positive and direct impact on the lake management.

Como Lo Hago Yo: Mielomeningocele En Bolivia  

PubMed Central

Introducción: Las malformaciones del tubo neural (MTN) representan la segunda causa más frecuente de anomalías congénitas, luego de las cardiopatías. En este grupo se destaca el mielomeningocele (MMC) por su mayor incidencia, y por ser la más incapacitante y la más compleja entre todas las demás malformaciones del sistema nervioso c`entral (SNC). En Bolivia, como en muchos países de Sudamérica, los bajos niveles socio-culturales y la debilidad en el sistema sanitario, hacen que su incidencia y su morbilidad, sean mayores que en las naciones más desarrolladas. Material y Métodos: Se realizó un estudio retrospectivo y descriptivo de 70 casos de MMC, atendidos por un equipo multidisciplinario en el Hospital Universitario Japonés (HUJ) de Santa Cruz de la Sierra, entre 2008-2011. De ellos, 60 fueron intervenidos quirúrgicamente. Resultados: Se realizaron controles prenatales sólo en 27 mujeres (38.6%), diagnosticándose una disrafia espinal en apenas dos casos (7.4%). La edad de ingreso del MMC en su mayoría fue después de las 24 horas (65.6%), predominando su localización en la región lumbosacra (64.3%). De ellos, 67.2% eran abiertos, presentando un 32.9% un daño neurológico motor parcial mientras que 47.1% tenían paraplejia por debajo de la lesión. De los 70 casos, tres (4.3%) no fueron intervenidos, por presentar defectos congénitos severos o estado general grave. Las principales complicaciones posoperatorias inmediatas fueron: dehiscencia de sutura y/o infección de la herida (16.6%), fístula de líquido cefalorraquídeo (LCR) (10%) e infección del SNC (11.7%). La mortalidad general y postoperatoria fue de 7.1% y 3.3%, respectivamente. Al mes de vida presentaban hidrocefalia un 80% de los pacientes operados, colocándose una derivación ventriculoperitoneal (DVP) de presión media. De 9 pacientes que tuvieron un acompanamiento de dos o más años, seis presentaron una médula anclada, que fueron intervenidas quirúrgicamente. Conclusión: En esta serie, el diagnóstico prenatal del MMC fue ocasional y la derivación al HUJ de los recién nacidos con esta malformación fue generalmente tardía. No hubo predominio de género y la mayoría de los casos presentaron sus lesiones en la región lumbar y lumbosacra. La mortalidad general y postoperatoria fue similar a la reportada en la literatura. Pocos enfermos realizaron controles posteriores al alta hospitalaria. Igual que otros países de Sudamérica, las falencias en el sistema público de salud y el nivel sociocultural, son factores determinantes para un mal pronóstico en estos niños. Por sus múltiples complicaciones, el MMC requiere de una especial atención gubernamental, sobre todo de carácter preventivo mediante el uso de ácido fólico en mujeres fértiles, como también de un equipo profesional multidisciplinario, a fin de realizar un tratamiento adecuado y oportuno. Al mismo tiempo, trabajos multicéntricos en hospitales de América Latina, ayudarán al mejor manejo de estos pacientes.

Evidence for a neurophysiologic auditory deficit in children with benign epilepsy with centro-temporal spikes.  

PubMed

Benign focal epilepsy in childhood with centro-temporal spikes (BECTS) is one of the most common forms of epilepsy. Recent studies have questioned the benign nature of BECTS, as they have revealed neuropsychological deficits in many domains including language. The aim of this study was to investigate whether the epileptic discharges during the night have long-term effects on auditory processing, as reflected on electrophysiological measures, during the day, which could underline the language deficits. In order to address these questions we recorded base line electroencephalograms (EEG), sleep EEG and auditory event related potentials in 12 children with BECTS and in age- and gender-matched controls. In the children with BECTS, 5 had unilateral and 3 had bilateral spikes. In the 5 patients with unilateral spikes present during sleep, an asymmetry of the auditory event related component (P85-120) was observed contralateral to the side of epileptiform activity compared to the normal symmetrical vertex distribution that was noted in all controls and in 3 the children with bilateral spikes. In all patients the peak to peak amplitude of this event related potential component was statistically greater compared to the controls. Analysis of subtraction waveforms (deviant - standard) revealed no evidence of a mismatch negativity component in any of the children with BECTS. We propose that the abnormality of P85-120 and the absence of mismatch negativity during wake recordings in this group may arise in response to the long-term effects of spikes occurring during sleep, resulting in disruption of the evolution and maintenance of echoic memory traces. These results may indicate that patients with BECTS have abnormal processing of auditory information at a sensory level ipsilateral to the hemisphere evoking spikes during sleep. PMID:16252074

We describe the case of a 15-year-old boy who had the diagnosis of benign partial epilepsy of childhood with centro-temporal spike. During the EEG a subclinical electrographic seizure was recorded. The discharges were clearly electropositive in T4 with positive phase reversal between derivations F8-T4 and T4-T6. The whole episode lasted less than one minute (45 sec). The interictal right medio-temporal spikes reemerged after 60 sec and were electronegative in the same location after the end of the electrographic seizures. The mechanisms underlying this uncommon pattern on EEG is not well established. PMID:7487536

Non-centro-symmetric electron diffraction pattern of icosahedral quasicrystal induced by combination of linear phason strain and curvature of Ewald sphere.  

PubMed

Non-centro-symmetric characteristics are observed in the experimental electron diffraction patterns (EDPs) from the icosahedral quasicrystalline precipitates in ZrAlNiCuNb alloys. Different from the well-known breaking of the Friedel's law, where a strong dynamical effect will reveal in EDPs the concealed non-centro-symmetry originated from the crystal structures themselves, the current results can be interpreted in terms of changes in deviation parameters due to a delicate combination of the linear phason strain characteristic of quasicrystals and the curvature of Ewald sphere. After taking this effect into consideration, the corresponding simulated EDPs fit quite well to the experimental data. PMID:24041584

Characterization of the matrix glass transition in carbon-epoxy laminates using the CSD test geometry. [centro-symmetric deformation  

NASA Technical Reports Server (NTRS)

A new test geometry, referred to as centro-symmetric deformation (CSD), is proposed for characterizing the viscoelastic behavior of the matrix of carbon-epoxy laminates. The sample consists of a thin disk, typically 6-14 plies thick, having a nominal diameter of 30 mm. The disk is freely supported on a circular anvil; the load is applied to the center of the disk using an 8-mm-diameter ball bearing nosepiece. The CSD test geometry provides viscoelastic dispersion data which are independent of the angular orientation of the sample. The test geometry is sufficiently sensitive to matrix changes to allow its use for postcuring, humidity, crosslink density, and other matrix change studies. Test results are presented for a carbon-epoxy laminate.

Co/Mo multilayers deposited by ion-beam sputtering  

NASA Astrophysics Data System (ADS)

Co/Mo multilayers have been prepared by using ion-beam sputtering. The samples had a periodic layered structure and an in-plane easy axis of magnetization. The structures of Co layers were disordered, fcc or fcc + hcp, depending upon the thickness of the Co layer ( tCo), as well as the thickness of the Mo layer ( tMo). A nonmagnetic compound, Co 7Mo 6, was observed to form at the Co/Mo interfaces, unlike compounds found in Co/Mo multilayers prepared by magnetron sputtering. The existence of this compound was considered to be an important reason for the decrease of the saturation magnetization of crystalline samples with tCo < 40 Å, among others. The dependence of the coercivity on tCo and/or tMo was also studied.

Spatial coherence of the ground motion produced by the 1979 Imperial Valley earthquake across El Centro Differential Array  

NASA Astrophysics Data System (ADS)

Spatial coherence of digitally recorded acceleration time histories across five elements of the El Centro Differential Array recorded during the October 15, 1979 Imperial Valley, California, earthquake is studied. Recorded within a total spacing of 214 m, the three-component time histories at five stations of this linear array provide a unique set of free-field data at sites of similar geology in the near field of a strong earthquake. The observed peak ground accelerations vary by as much as 43, 13 and 40% on the E-W, N-S and vertical components. It is shown that the incoherence of high frequency waves brought about by wave scattering near the receiver is partially responsible for the observed variation. This is evident from the frequency dependent reduction of the peak cross-correlation amplitudes of the strong phase of ground shaking. The observed reductions increase from ˜ 1% below 1 Hz to 20-30% in the 1-10 Hz band and to nearly 80% above 10 Hz. Investigation of the polarization angle of P-wave coda indicates that high frequency waves (> 10 Hz) approach the recording station randomly from nearly all directions. The peak cross-correlation of the polarization angle in general is lower than that of amplitudes. The successive sampling of this angle in the low frequency band suggest a northwestward propagation of the source during the faulting process.

Valorisation of Como Historical Cadastral Maps Through Modern Web Geoservices  

NASA Astrophysics Data System (ADS)

Cartographic cultural heritage preserved in worldwide archives is often stored in the original paper version only, thus restricting both the chances of utilization and the range of possible users. The Web C.A.R.T.E. system addressed this issue with regard to the precious cadastral maps preserved at the State Archive of Como. Aim of the project was to improve the visibility and accessibility of this heritage using the latest free and open source tools for processing, cataloguing and web publishing the maps. The resulting architecture should therefore assist the State Archive of Como in managing its cartographic contents. After a pre-processing consisting of digitization and georeferencing steps, maps were provided with metadata, compiled according to the current Italian standards and managed through an ad hoc version of the GeoNetwork Opensource geocatalog software. A dedicated MapFish-based webGIS client, with an optimized version also for mobile platforms, was built for maps publication and 2D navigation. A module for 3D visualization of cadastral maps was finally developed using the NASA World Wind Virtual Globe. Thanks to a temporal slidebar, time was also included in the system producing a 4D Graphical User Interface. The overall architecture was totally built with free and open source software and allows a direct and intuitive consultation of historical maps. Besides the notable advantage of keeping original paper maps intact, the system greatly simplifies the work of the State Archive of Como common users and together widens the same range of users thanks to the modernization of map consultation tools.

Morphological investigation of nanostructured CoMo catalysts  

NASA Astrophysics Data System (ADS)

This work reports the morphological investigation of nanostructured sulfided CoMo catalysts by means of high-resolution transmission electron microscopy (HRTEM). The catalysts were supported on Ti-modified hexagonal mesoporous silica (HMS-Ti) and P-modified HMS-Ti (P/HMS-Ti) materials. The oxide precursors were characterized by specific surface area (S BET), temperature-programmed reduction (TPR), diffuse reflectance infrared Fourier transform spectroscopy in the OH region (DRIFTS-OH) and X-ray photoelectron spectroscopy (XPS) in order to elucidate the influence of the impregnation sequence (successive vs. simultaneous) and the effect of P-incorporation into HMS-Ti material on the morphology of calcined CoMo catalysts. Both TPR and XPS measurements indicate that the catalysts prepared by successive impregnation possess well-dispersed MoO 3 and CoO phases, whereas their counterparts prepared by simultaneous impregnation additionally possess the CoMoO 4 phase. For all sulfided catalysts, the presence of MoS 2 phase with particle size in the range 3.3-4.4 nm was confirmed by HRTEM. Catalytic activity was evaluated in the reaction of hydrodesulfurization (HDS) of dibenzothiophene (DBT) carried out in a flow reactor at 593 K and hydrogen pressure of 5.5 MPa. P-incorporation into the HMS-Ti material led to an overall increase in HDS activity and the hydrogenation ability of the sulfided catalysts. All catalysts proved to be stable during 10 h time-on-stream (TOS) operation. The activity of sulfide catalysts in the target reaction depends linearly on the surface exposure of Co species in the oxide precursors, as determined by XPS, and on the morphology of the sulfide form of catalysts (surface density of MoS 2 particles and their sizes) as determined by HRTEM.

Progressive coaxial Variscan deformation in the Centro-Iberian Zone (Portugal): Serra do Moradal-Fajao complex syncline  

NASA Astrophysics Data System (ADS)

The Serra do Moradal-Fajão syncline is a major NNW-SSE Variscan structure developed in the SW sector of the Centro-Iberian Zone, one of the main geodynamical structures of the Iberian Variscides. This tight syncline with a 1.5 km wavelength, could be followed for more than 80 km and represents one of the most important regional structures. Its complex structure has been possible to characterize, not only due to excellent outcrop condition (mostly induced by the competent behaviour of the Lower Ordovician Armorican Quartzite Formation), but also to the detailed lithostratigraphic control of the Ordovician-Silurian lithologies. These units are present in a homogeneous regional distribution, unconformably overlain the Cambrian Beiras Group. Concerning the Variscan structures, their geometry and kinematics show that they could be ascribed to progressive deformation induced by the first and main D1 tectonic event. During this event, a complex NNW-SSE aggregation of fold and thrust arrays have been developed. At the macroscale, this pattern is mainly characterized by the Serra de Moradal-Fajão syncline. Both limbs of this major D1 Variscan fold, which present a slightly ENE facing, have been disrupted by convergent thrust systems, leading to the superposition of the Cambrian Beiras metasediments on top of the Ordovician-Silurian succession. Concerning its SW limb, a major single overthrust has been developed, the Vilar Barroco-Fajão one, although in some very localized sectors, some minor thrusts could be emphasized; as they present a ENE facing, they are interpreted as duplex style forethrusts in relation to the main overthrust. Regarding the NE limb, a different behaviour is found. Indeed, in this sector, an imbricated thrust system has been mapped; due to their WSW facing it should be considered as backthrusts. Concerning the temporal relations between the previously described structures, although in some rare cases backthrusts cut forethrusts, the scarcity of interference structures turns difficult the subdivision of the main tectonic Variscan phase in sub-events of regional meaning. Indeed, the described geometries and kinematics could be the result of progressive deformation in a coaxial regime. This coaxial deformation is also consistent with the mesoscopic Variscan structures of the Serra de Moradal-Fajão syncline. In fact, not only the geometry of the minor folds are similar to the major syncline, but also the coeval S1 cleavage presents an axial plane behaviour, emphasized by the regularity of the intersection L1 lineation, which is subparallel to the fold axes. Both the folds and the thrusts are distorted at the cartographic scale by ductile shear zones: N-S to NNE-SSW dextral and WNW-ESE to E-W sinistral. As these structures could be interpreted as conjugate shears induced by a stress field fully compatible with the D1 Variscan tectonic event they are considered as lateral ramps of the main thrust system. Some of the previous planar anisotropies are reactivated in a brittle regime during the late-Variscan orogenic cycle: mainly the N-S to NNE-SSW behaves as sinistral strike-slip faults. Alpine reactivation by NNW-SSE compression (Cebola reverse fault of the Central Cordillera system) induces also sinistral strike-slip on NE-SW and dextral strike-slip on ENE-WSW previous Variscan faults.

Introducing CAT (Centro di Allerta Tsunami), the Italian candidate Tsunami Watch Provider (It-cTWP) for the Mediterranean  

NASA Astrophysics Data System (ADS)

The recently established CAT (Centro di Allerta Tsunami) at Istituto Nazionale di Geofisica e Vulcanologia (INGV) will be part of the Italian National Tsunami Warning Center (It-NTWC) and it is a candidate Tsunami Watch Provider (cTWP) for the Mediterranean Sea in the framework of the Tsunami Early Warning and Mitigation System in the North-eastern Atlantic, the Mediterranean and connected seas (NEAMTWS). It-NTWC is a partnership of three Italian institutions: INGV, the Italian Department of Civil Protection (Dipartimento di Protezione Civile, DPC) and the Institute for Environmental Protection and Research (Istituto Superiore per la Protezione e la Ricerca Ambientale, ISPRA) which provides the sea-level data of the Italian mareographic network (Rete Mareografica Nazionale, RMN) in quasi-real-time. CAT is the operational part of the It-NTWC based at the INGV 24/7 seismic monitoring centre in Rome. CAT will be committed to deliver tsunami warning messages to DPC and, when it will enter its operational cTWP phase, to any IOC/UNESCO member state that will subscribe for the service. The current implementation of CAT is based on the NEAMTWS Decision Matrix (DM). Earthquake parameters are determined automatically by the Early-Est (EE) software, and used as an input to DM and tsunami travel times calculation to provide warning messages, including earthquake parameters, plus level of alert and estimated tsunami arrival time at pre-defined forecast points along threatened coasts. Basing on updated automatic EE solutions, seismologist's revision, and sea-level readings subsequent messages can be delivered until warning status ends. The use of the DM allows a rapid implementation of a tsunami warning system, but it does not consider some important features to better characterize a tsunami forecast, such as the earthquake's focal mechanism, the directivity of tsunami propagation and the morphology of the coast. More sophisticated procedures are currently under development: a database of pre-calculated, or calculated on the fly on GPU cards, tsunami scenarios, and rapid moment tensor calculation. The deployment of deep-sea tsunami (pressure) sensors is envisaged as well subject to budgetary constraints. A Decision Support System (DSS) is under development in order to integrate the different sources of information (earthquake parameters estimates and prior knowledge of the tectonic setting, numerical tsunami forecast, sea-level readings), and assist decision making during the first minutes after an event. CAT participated successfully in several NEAM communication tests within its function of National Tsunami Warning Focal Point (NTWFP) and the delivery of messages to DPC, ISPRA, and local authorities has also been tested. Preliminary CAT procedures have been tested internally, that is without delivering messages, also for two recent Mediterranean earthquakes: the M=6.6 occurred the 12th October 2013 offshore Crete and the M=5.9 occurred the 28th December 2013 offshore between Turkey and Cyprus. Here, we will present the current CAT implementation and describe its future developments.

Hydrologic flowpaths and biogeochemical cycles in the subalpine Como Creek catchment, Colorado Front Range, USA  

NASA Astrophysics Data System (ADS)

An outstanding question for snowmelt-dominated watersheds of the western US are the responses of biogeochemical processes to two major drivers of environmental change: directional changes in climate and increasing dissolved inorganic nitrogen (DIN) deposition in wetfall. In the Colorado Front Range, atmospheric deposition of DIN has increased several-fold in the last 25 years. In response, nitrate concentrations at the alpine Green Lakes 4 (GL4) catchment have increased from 1985 to 2009 by 0.27 ?eq L-1 yr-1. In contrast, we see no directional change in either nitrate concentrations or fluxes in the subalpine Como Creek catchment. We hypothesize that differences in surface/groundwater interactions result in the differing behavior of stream nitrate between the alpine and subalpine catchments that are receiving similar amounts of DIN from atmospheric deposition. For both basins we sampled precipitation, snowpack, snowmelt, surface water, and subsurface waters. All water samples are analyzed for geochemical, nutrient and isotopic (?18O, ?D) composition. Stream chemistry data from the last ten years at Como Creek show increases in nitrate concentration during baseflow conditions and then a sharp decline during snowmelt. In contrast, in the alpine basin there is sharp increase in surface water nitrate during snowmelt. Hydrograph separation at the alpine GL4 using end member mixing analysis (EMMA) shows that stream flow is a mixture of three components, groundwater, talus, and new snowmelt that each contribute to roughly a third of discharge, with talus flow supplying the majority of nitrate. In contrast, and somewhat surprisingly, EMMA shows that for the subalpine Como Creek basin, annual streamflow is a mixture of only two components, groundwater and new snowmelt. During snowmelt the groundwater and snow contributions are nearly equal and subsurface flows dominate the remainder of the year. Newly installed piezometers at Como Creek provide evidence that the basin is largely a losing reach during snowmelt, with water levels in the piezometers increasing 5-7 m. After peak snowmelt however, Como Creek becomes a gaining stream, with piezometer levels dropping. Thus, both EMMA and piezometers show that surface-groundwater interactions are tightly coupled during snowmelt, with snowmelt at Como first replenishing the subsurface water deficit and increasing groundwater levels before contributing to discharge. Thus, in contrast to the alpine GL4 basin, DIN released in snowmelt is assimilated belowground as snowmelt infiltrates the subsurface in the subalpine basin. Interestingly, at the subalpine Como Creek basin, isotopic and geochemical solute concentrations undergo shifts during periods of winter baseflow prior to snowmelt. In winter much of the stream is frozen and we hypothesize that cryo-concentration of solutes and fractionation of isotopes may influence the concentrations of winter stream samples.

Characterization of K 2CO 3/Co-MoS 2 catalyst by XRD, XPS, SEM, and EDS  

NASA Astrophysics Data System (ADS)

MoS 2, Co-MoS 2 and K 2CO 3/Co-MoS 2 catalysts have been characterized by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). XRD analysis indicates that Co-MoS 2 is a primary phase in K 2CO 3/Co-MoS 2 catalyst and the diffraction lines of Co-MoS 2 are not changed by the addition of K 2CO 3. Co 9S 8 phase is not present at Co/Mo mole ratio of 0.5 using a co-precipitation method for preparation of cobalt-molybdenum catalyst. The binding energies (BEs) of chemical species present on the surface of the catalysts are compared through the course of catalyst preparation. K 2CO 3/Co-MoS 2 catalyst has been investigated as a function of dispersion of K on the surface and exposure to a mixture of carbon monoxide and hydrogen (syngas) by scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS). The distribution of potassium on the surface of the K-promoted catalyst is not uniform.

NASA Astrophysics Data System (ADS)

Este trabalho visa analisar a possibilidade de relacionar conteúdos aplicados no ensino fundamental e médio de forma interdisciplinar por intermédio da astronomia, com a intervenção de objetos de aprendizagem que possam integrar as disciplinas e a utilização de recursos tecnológicos. Em uma pesquisa prévia com 20 professores de uma escola estadual situada na cidade de Guarulhos foi observado que apenas 25% dos professores utilizam algum recurso tecnológico para o desenvolvimento de conteúdos pertinentes à sua disciplina, tais como sites e softwares educativos, sendo que a maioria absoluta continua ensinando apenas com livros didáticos. A maior parte dos professores apresenta dificuldades em trabalhar sua disciplina de forma interdisciplinar, ou seja, 75% dos professores preferem aplicar os conteúdos seguindo uma hierarquia linear de tópicos, evitando a discussão de temas que de alguma forma estão relacionados. A astronomia pode vir à fascinar o ser humano e despertar sua curiosidade promovendo um maior interesse no aprendizado, podendo favorecer análises interdisciplinares de forma lógica e objetiva, desta forma colocar a astronomia como tema motivador interdisciplinar, pode ser relevante no que se refere ao distanciamento da fragmentação dos conteúdos. No Estado de São Paulo, a implantação da proposta curricular no ensino fundamental e médio mostra claramente a inserção da astronomia na maior parte das séries, principalmente na 6ª série em que todo o bimestre se fala de astronomia.

A Geostatistical Approach to Reducing Uncertainty in Rainfall Estimates Using Terrain Characteristics: A Case Study in the Central-North Regional Water Administration of Mozambique (ARA Centro-Norte)  

NASA Astrophysics Data System (ADS)

Many data-sparse regions, such as southern Africa, will likely face significant changes in water resources availability and timing in the future due land use change, climate change and population growth. Improved estimates of rainfall and streamflow are necessary to improve water resources decision-making, risk management, and uncertainty quantification. In this study, we use a universal kriging framework to associate various watershed terrain characteristics with gauged rainfall data to improve the estimation of monthly rainfall fields. We focus on available gauge data because other precipitation data sources, such as satellite precipitation products, are unavailable over historic periods of interest and exhibit bias in our context of streamflow estimation. Our study area is the 185,000 sq km Central-North Regional Water Administration of Mozambique (ARA Centro-Norte), which is predominantly rural tropical savanna. We use fifty years of spatially and temporally sparse monthly rainfall observations from 316 rainfall gauges. Most of the watershed terrain characteristics we use are derived from the 90m HydroSHEDS Digital Elevation Model dataset. These include elevation, aspect, slope, distance to large water bodies, distance to ridges, and distance to watershed rainfall maximum. We quantify the importance of these characteristics for reducing uncertainty in rainfall estimates using the Bayes information criterion (BIC) approach. Future work includes using these rainfall estimates to drive the semi-distributed monthly time-step Pitman rainfall-runoff model, in order to reduce uncertainty in streamflow estimates in gauged and ungauged basins.

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.

In order to obtain a hydrogen electrode with high-performance and stability for H 2-O 2 alkaline fuel cells, Brewer-type Co-Mo alloys are manufactured in the 35 to 57 wt.% Mo composition range by an arc-melting method. The electrochemical stability of alloys composed of Co 3Mo and Co 7Mo 6 phases is investigated in hot KOH solution deaerated with N 2 gas by means of electrochemical methods such as cyclic voltammetry, potentiostatic polarization and potentiodynamic polarization. Co-Mo alloy is extensively dissolved because the cobalt in alloy is soluble in hot KOH solution. The dissolution current of the alloys increases with increasing electrolyte temperature, electrolyte concentration and Mo content in the alloy.

Hydrotreatment of Athabasca bitumen derived gas oil over Ni-Mo, Ni-W, and Co-Mo catalysts  

SciTech Connect

The hydrotreatment of Athabasca bitumen derived heavy gas oil containing 4.08% S and 0.49% N was carried out in a trickle bed reactor over Ni-W, Ni-Mo, and Co-Mo catalysts supported on zeolite-alumina-silica at 623-698 K, LHSV of 1-4, gas flow rate 890 m[sup 3][sub H2]/m[sup 3][sub oil] (5,000 sef/bbl), and pressure of 6.89 MPa. Analyses for viscosity, density, aniline point, ASTM mid boiling point distillation, C/H ratio, and percentage of N and S in the final product were carried out to characterize the product oil. The amounts of N and S removed indicated the hydrodenitrogenation and hydrodesulfurization activity of the catalysts. Results of zeolite-alumina-silica-supported catalysts are compared to those obtained with commercially available Ni-Mo, Ni-W, and Co-Mo on [gamma]-alumina. Ni-Mo supported on zeolite-alumina-silica was most active and could remove as much as 99 % S and 89% N present in the oil at 698 K. The data for HDN and HDS fitted the pseudo first order model. The kinetic model is described in detail.

Extended x-ray absorption fine structure determination of the structure of cobalt in carbon-supported Co and Co-Mo sulfide hydrodesulfurization catalysts  

SciTech Connect

The structure of the cobalt present in carbon-supported Co and Co-Mo sulfide catalysts was studied by means of x-ray absorption spectroscopy at the Co K-edge and by X-ray photoelectron spectroscopy (XPS). Thiophene hydrodesulfurization activities were used to measure the catalytic properties of these catalysts. By comparison of the EXAFS and XANES spectra of the catalysts with those of Co{sub 9}S{sub 8} and CoS{sub 2} model compounds, it was concluded that all Co atoms in a catalyst prepared with nitrilotriacetic acid as complexing agent were in the Co-Mo-S state, while the Co atoms in a conventionally prepared catalyst were partly present in a Co{sub 9}S{sub 8}-like structure and partly in a Co-Mo-S structure. The Co atoms in the Co-Mo-S state have a distorted 5- to 6-fold sulfur coordination, and on the average, every Co atom is in contact with two Mo atoms at a distance of 2.80 {angstrom}. On the basis of these data, the most likely position for the Co atoms is in front of the square sulfur faces of the MoS{sub 6} trigonal prisms along the edges of the MoS{sub 2} crystallites with two additional sulfur atoms or H{sub 2}S molecules attached.

Influence of the Additives and The pH On the Cobalt-Molybdenum (Co-Mo) Alloy Electrodeposited On n-TypeSilicon  

NASA Astrophysics Data System (ADS)

In this work, thin films of metal alloys (Co-Mo) have been electrodeposited onto silicon (Si) surface. The effects of two different additives (H3BO3 and Na2CO3) and the pH of the solution on the electrochemically deposited films (morphology, stochiometry…) have been investigated. The properties of the deposits were characterized by using X-Rays Diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS). The results show that the morphology and the film composition depend on both the pH of the solution and the additives. The presence of boric acid favors the Mo deposition. Crack-free homogeneous deposits with a low percentage of molybdenum can be easily obtained from high pH bath. The deposits were shown to exhibits a good crystalline structure.

Structure of the molybdenum sulfide phase in carbon-supported Mo and Co-Mo sulfide catalysts as studied by extended x-ray absorption fine structure spectroscopy  

SciTech Connect

The structure and dispersion of the active phase present in carbon-supported Mo and Co-Mo sulfide catalysts were studied by means of Mo K-edge EXAFS. In situ EXAFS measurements were carried out at liquid N{sub 2} temperature on freshly sulfided (at 673 K) catalysts. Due to the high signal-to-noise ratio of the experimental data, detailed information about the structural parameters of the active phase could be obtained. The catalysts probably consist of small MoS{sub 2}-like particles with an average local ordered structure of 5-6 Mo atoms (Mo/C) and 7-8 Mo atoms (Co-Mo/C). Comparison with literature data shows that the MoS{sub 2} dispersion in these carbon-supported catalysts is probably as good as in their alumina-supported counterparts.

A Influência da Escola e da Mídia na Obtenção dos Conhecimentos Astronômicos  

NASA Astrophysics Data System (ADS)

O universo em que vivemos possui segredos jamais imaginados pelo homem, fruto da pequena proporção que ocupamos diante de um cosmos infinito. A astronomia funciona como um instrumento que sacia a sede humana em desvendar esses segredos, estudando as galáxias, quasares, pulsares além da existência de todos os elementos que preenchem o espaço cósmico, o vácuo, não mais vazio como se pensou em outros tempos. A mídia explora esse campo de forma mística e também científica. A difusão adequada e dentro dos padrões educacionais vigentes, de conceitos astronômicos, se faz necessária, devido sua presença nos conteúdos escolares, centros de ciência e na mídia, de modo geral. A reforma do Currículo Básico da Escola Pública da maioria dos Estados brasileiros introduziu conceitos astronômicos desde a pré-escola até o Ensino Médio. Num estudo realizado com 1.032 alunos do Ensino Médio de seis escolas estaduais, revelou-se através da aplicação de um questionário que abordava conheciment os básicos em astronomia, como estes foram adquiridos e qual era a infra-estrutura oferecida pela escola: para 66,2% dos entrevistados o professor já fez alguma apresentação a respeito de astronomia. O presente estudo revelou também que 44,5% dos alunos entrevistados adquiriram seus conhecimentos astronômicos na escola, 28,1% através da televisão e 27,4% afirmaram que seus conhecimentos foram obtidos através de outros tipos de mídia (internet, filmes e revistas). Embora o estudo revele claramente que há certo equilíbrio na forma em que os alunos obtiveram seus conhecimentos astronômicos, a mídia ainda explora e muitas vezes desperta o interesse pela astronomia com assuntos que não fazem parte de nosso cotidiano como, por exemplo, o homem na Lua, os projetos espaciais e a primeira viagem de um astronauta brasileiro no espaço. Porém, em certos casos, a mídia pode promover conhecimentos incompletos ou mesmo equivocados sobre os conceitos que envolvam a astronomia, como por exemplo a propagação do som no vácuo observado na maioria dos filmes de f icção científica ou da existência das estações do ano em função da distância da Terra ao Sol, em conformidade com o questionário aplicado.

Thermal effects on Co/Mo2C multilayer mirrors studied by soft x-ray standing wave enhanced photoemission spectroscopy  

NASA Astrophysics Data System (ADS)

Here is presented the spectroscopic study of the evolution of the first buried interfaces of a B4C capped Co/Mo2C multilayer mirror induced by thermal treatment up to 600°C. This kind of study is typically performed to simulate the response of multilayer optics working in extreme conditions, as for instance when irradiated by new high brilliance sources as Free Electron Lasers. In fact, the efficiency of multilayers is related to the optical contrast between the alternating high and low density layers, and then to the degree of interdiffusion and the creation or evolution of interface compounds. The analysis has been performed at the Co L23 edge with different soft x-ray spectroscopic techniques including diffuse and specular reflectivity, total electron and fluorescent yield at the BEAR beamline at Elettra (Trieste) (http://www.elettra.trieste.it/elettra-beamlines/bear.html). The presentation is focused on the spectroscopic results obtained by soft x-ray standing wave enhanced photoemission (XSW) from the Mo 3d, B 1s, C 1s, O 1s core levels by using a photon energy close to the Co L23 edge and corresponding to the first Bragg peak of the multilayer. The experimental results have been compared with simulations to obtain information both on the chemical state (e.g. oxidation state) and interface morphology in terms of profiles of distribution of elements and interdiffusion of B, oxidized B and C in the interface region. In summary, it is possible to conclude in favour of a good stability of the multilayer in the investigated temperature range, as confirmed by the good performance in terms of reflectivity. These results confirm the usefulness of XSW for this kind analysis of multilayer optics.

A previous study by the U.S. Geological Survey of impaired water bodies in Fort Worth, Texas, reported elevated but variable concentrations of particle-associated contaminants (PACs) comprising chlorinated hydrocarbons, polycyclic aromatic hydrocarbons, and trace elements in suspended and bed sediment of lakes and streams affected by urban land use. The U.S. Geological Survey, in cooperation with the City of Fort Worth, collected additional samples during October 2004 to investigate sources of PACs in the watersheds of two impaired lakes: Lake Como and Fosdic Lake. Source materials and aquatic sediment were sampled and analyzed for PACs. Source materials sampled consisted of street dust and soil from areas with residential and commercial land use and parking lot dust from sealed and unsealed parking lots. Aquatic sediment sampled consisted of bottom-sediment cores from the two lakes and suspended and streambed sediment from the influent stream of each lake. Samples were analyzed for chlorinated hydrocarbons (organochlorine pesticides and polychlorinated biphenyls), polycyclic aromatic hydrocarbons, major and trace elements, organic carbon, grain size, and radionuclides.

In this work, we extend Young's result to a more realistic case, namely an inhomogeneous galactic center, although keeping the spherical symmetry hypothesis, in order to verify whether the final density profile changes.

Language in benign childhood epilepsy with centro-temporal spikes abbreviated form: rolandic epilepsy and language.  

PubMed

Although Benign Childhood Epilepsy with Centrotemporal Spikes (BECTS) has a good prognosis, a few studies have suggested the existence of language disorders relating to the interictal dysfunction of perisylvian language areas. In this study, we focused on language assessment in 16 children aged 6-15 currently affected by BECTS or in remission. An important proportion of children showed moderate or more severe language impairment. The most affected domains were expressive grammar and literacy skills. We found linguistic deficits during the course of epilepsy but also persistent deficits in children in remission, suggesting possible long-term effects. Our results support the hypothesis that BECTS may be associated with impairment to language and suggest the possibility of a direct link between epileptic activity and language development, and the existence of long-term consequences.

Desulfurization of benzenethiol on Co?Mo(110) phases  

Microsoft Academic Search

The desulfurization of benzenethiol on Co-covered Mo(110) (?Co = 0.25–1.3 ML) produces benzene, H2 and adsorbed carbon and sulfur. Benzene is formed via adsorbed phenyl thiolate, which is identified by X-ray photoelectron and electron energy loss spectroscopies. Benzene production is attributed to reaction on Co, since it is evolved at a temperature well below that required for sulfur-induced aggregation of

Molecular diagnosis of haemophilia A at Centro Hospitalar de Coimbra in Portugal: study of 103 families--15 new mutations.  

PubMed

Haemophilia A (HA), the most commonly inherited bleeding disorder, has well known phenotype heterogeneity, influenced by the type of mutation, modulating factors and development of inhibitors. Nowadays, new technologies in association with bioinformatics tools allow a better genotype/phenotype correlation. With the main objective of identifying familial carrier women and to offer prenatal diagnosis, 141 HA patients belonging to 103 families, followed or referred to the Haemophilia Centre of CHC, E.P.E., were studied. Molecular diagnosis strategy was based on HA severity: IVS22 and IVS1 inversions, direct sequencing and MLPA technique. New missense and splicing mutations were further analyzed using molecular modelling. Genotype/phenotype correlation was assessed taking into account the known modulating factors. During this study, mutations were detected in 102/103 families, carrier status was determined in 83 women and 14 prenatal diagnoses were performed. In a total of 46 different mutations identified, 15 have not been reported previously by the HAMSTeRS and HGMD. Genotype/phenotype correlation revealed two cases with a clinical picture less severe than expected by the type of mutation identified. Six patients developed inhibitors: five severe (IVS22, IVS1, large deletion) and one mild (p. Gln2265Lys). The adopted strategy allowed the identification of 99% of the molecular alterations underlying the HA phenotype (98% detection rate for severe and 100% for moderate and mild). Evaluation of genotype-phenotype correlation was complemented with structural protein modelling of newly identified missense mutations, contributing to better understanding of the disease-causing mechanisms and to deepening knowledge on protein structure-function.

RESUMEN Fundamento: En 2008, se puso en marcha el programa Ni ogros ni princesas en 12 centros de secundaria de Asturias (España) para incorporar la educación afectivo-sexual. El programa proponía 14 actividades, dirigidas a alumnado, profesorado y familias. Este estudio recoge la evaluación de proceso de esta intervención, en relación a la ejecución de las actividades, participación, satisfacción, utilidad percibida y propuestas de mejora. Métodos: La población de estudio fueron los 12 centros que participaron en el programa, y su alumnado, profesorado y familias. Se obtuvo información sobre la ejecución de actividades mediante un cuestionario de seguimiento; se recogió la satisfacción y utilidad percibida con cuestionarios auto-administrados para alumnado y profesorado; también se recogieron sus propuestas de mejora, y las de las familias, en grupos focales. Resultados: El número medio de actividades realizadas por los 12 centros fue 11,6. Se implicaron 185 docentes (26%), que impartieron sesiones al 81% del alumnado en estos 12 centros. El número medio de sesiones impartidas fue 6 en cada nivel de la ESO. El 79% del profesorado se sintió bastante/muy satisfecho con su actuación y al 65% del alumnado le gustaron bastante/mucho estas sesiones. Más del 60% de estudiantes y docentes consideraron que estas sesiones servían bastante/mucho para aumentar conocimientos, reflexionar, mejorar la igualdad, conocer otras opiniones y favorecer el respeto a la diversidad sexual. Entre las propuestas de mejora, más horas para la educación sexual, liberación horaria para el profesorado, y más actividades para familias. Conclusiones: El programa fue una intervención novedosa y percibida como útil para incorporar la educación sexual en los centros de secundaria, ya que contó con un gran nivel de ejecución, así como una alta participación, satisfacción y utilidad percibida por el alumnado y profesorado.

We present the results on the age estimates of 11 Small Magellanic Cloud (SMC) clusters obtained for the first time from CCD Washington CT1 T2 photometry. CMD cluster features - mainly cluster RCs and MSTOs - turn out to be identificable when performing annular extractions around their re- spective centres, once they were cleaned from field star contamination. We estimated ages for the cluster sample using the T1 index, and metallicities from the SGB technique. The resultant ages and metallicities for the control clusters are in excellent agreement with those previously published, thus confirming our present age/metallicity scale. We also confirmed the ages and metallicities derived for the clusters by fitting theoretical isochrones. FULL TEXT IN SPANISH

Astronomia para/com crianças carentes em Limeira  

NASA Astrophysics Data System (ADS)

Em 2001, o Instituto Superior de Ciências Aplicadas (ISCA Faculdades de Limeira) iniciou um projeto pelo qual o Observatório do Morro Azul empreendeu uma parceria com o Centro de Promoção Social Municipal (CEPROSOM), instituição mantida pela Prefeitura Municipal de Limeira para atender crianças e adolescentes carentes. O CEPROSOM contava com dois projetos: Projeto Centro de Convivência Infantil (CCI) e Programa Criança e Adolescente (PCA), que atendiam crianças e adolescentes em Centros Comunitários de diversas áreas da cidade. Esses projetos têm como prioridades estabelecer atividades prazerosas para as crianças no sentido de retirá-las das ruas. Assim sendo, as crianças passaram a ter mais um tipo de atividade - as visitas ao observatório. Este painel descreve as várias fases do projeto, que envolveu: reuniões de planejamento, curso de Astronomia para as orientadoras dos CCIs e PCAs, atividades relacionadas a visitas das crianças ao Observatório, proposta de construção de gnômons e relógios de Sol nos diversos Centros Comunitários de Limeira e divulgação do projeto na imprensa. O painel inclui discussões sobre a aprendizagem de crianças carentes, relatos que mostram a postura das orientadoras sobre a pertinência do ensino de Astronomia, relatos do monitor que fez o atendimento no Observatório e o que o número de crianças atendidas representou para as atividades da instituição desde o início de suas atividades e, em particular, em 2001. Os resultados são baseados na análise de relatos das orientadoras e do monitor do Observatório, registros de visitas e matérias da imprensa local. Conclui com uma avaliação do que tal projeto representou para as Instituições participantes. Para o Observatório, em particular, foi feita uma análise com relação às outras modalidades de atendimentos que envolvem alunos de escolas e público em geral. Também é abordada a questão do compromisso social do Observatório na educação do público em questão.

Observaciones del disco solar y de una protuberancia quiescente en radiación ultravioleta  

NASA Astrophysics Data System (ADS)

Observaciones del disco solar y de una protuberancia quiescente en el rango de longitudes de onda ultravioleta fueron obtenidas con el instrumento CDS (Coronal Diagnostic Spectrograph) y SUMER (Solar Ultraviolet Measurements of emitted radiation) a bordo de la sonda SOHO. El propósito es investigar las velocidades macroscópicas de varias especies metálicas que se observan tanto en el disco solar como en el plasma de las protuberancias. Para calcular las velocidades del disco solar aplicamos una técnica mixta para modelar la distribución de estructuras en UV en el Sol quieto. Las velocidades macroscópicas en las protuberancias se calcularon a partir de los corrimientos Doppler en cada línea espectral y luego se tomaron las del disco solar como referencia. Obtuvimos valores absolutos para las velocidades macroscópicas entre 5 y 40 km/seg. También detectamos comportamientos diferentes en las velocidades de las protuberancias en el centro con respecto a los bordes.

Um Projeto de Intervenção nos Espaços de Exposições do Planetário do Parque do Ibirapuera  

NASA Astrophysics Data System (ADS)

Cada vez mais a humanidade, em sua imensa maioria, está alheia às próprias conquistas. A insatisfação com esta realidade tem levado muitos pesquisadores, instituições, empresas e governos a procurar formas alternativas de acompanhar e transmitir todo este acervo científico cultural à sociedade, buscando a melhoria da qualidade da divulgação científica e contribuindo para o processo de cultura e alfabetização científica. Não há tempo nem espaço nos limitados planos curriculares do ensino médio e mesmo nos programas de ensino que propiciem a cultura científica e o acompanhamento do vertiginoso progresso científico e tecnológico atual. Neste sentido, a educação formal escolar precisa ser complementada ou acrescida de uma educação informal, extra-escolar, que possa oferecer à sociedade o que a escola não pode oferecer. A interação do público com museus, feiras de ciências, planetários, exposições científicas e/ou culturais é de grande importância para a aquisição e difusão de conhecimentos relacionados ao mundo científico. Reconhecidamente como um modelo de alfabetização científica esses ambientes promovem uma interação social capaz de propiciar de forma efetiva uma melhor relação ensino-aprendizagem com o público. Partindo desta realidade a Universidade Cruzeiro do Sul e a Escola Municipal de Astronomia (EMA) vêm desenvolvendo um projeto de intervenção no espaço em torno do Planetário do Parque do Ibirapuera com o objetivo de se implantar um ambiente de aprendizagem motivador e desafiador que promova a popularização de conteúdos relacionados à astronomia, astrofísica e cosmologia. Busca-se, também, a aproximação e interação do público com exposições que estão sendo implementadas no planetário. Considerando que se trata de um projeto de mestrado em fase inicial o objetivo do presente trabalho é apresentar a concepção básica e os critérios que estão sendo utilizados do ponto de vista pedagógico para as indicações dos objetos e experimentos que serão expostos, procurando formas de construir, expor e apresen! tá-los d e maneira mais eficiente em termos de uma aprendizagem significativa.

Astronomía Gamma desde El Leoncito  

NASA Astrophysics Data System (ADS)

La astronomía gamma, en el extremo de energías detectadas hasta el presente, se encuentra en desarrollo en muchas partes del mundo y proporciona resultados sorprendentes a medida que la tecnología avanza en el desarrollo de nuevos detectores. La técnica Cherenkov Atmosférica es la utilizada para la detección, mediante telescopios en tierra, del efecto secundario causado por la radiación gamma de muy altas energías (E ? TeV). Por medio de telescopios o arreglos de detectores y utilizando la técnica mencionada, se han podido detectar algunas fuentes puntuales de mucha importancia astrofísica como la Nebulosa del Cangrejo y la galaxia de núcleo activo Markarian 421. El sistema instalado en San Juan, en cooperación con el grupo de Radiación Gamma del Observatorio Whipple, está constituído por tres colectores de 1.5m que registran pulsos de luz generados por las cascadas de partículas producidas por rayos cósmicos de todo tipo al entrar en la atmósfera terrestre. El sistema opera por barrido en ascención recta de la fuente observada que, para esta etapa del experimento, es el Centro Galáctico. Esta fuente extensa es conocida como emisor gamma de energías inferiores al TeV y ha sido observada anteriormente en este rango de energía desde el hemisferio norte pero con elevaciones bajas, situación no óptima para este tipo de técnica. Se presentan los primeros resultados del análisis de los datos obtenidos observando la región del Centro Galáctico, luego de dos años de observaciones, así como una descripción de la técnica Cherenkov Atmosférica y del equipo utilizado en la experiencia.

Tetrahydrothiophene desulfurization on Co-Mo/. gamma. -Al sub 2 O sub 3 : A temporal analysis of products (TAP) investigation  

SciTech Connect

The catalytic reactions of tetrahydrothiophene, thiophene, 1-butene, 1,3-butadiene, and n-butane with hydrogen were studied at low pressure over a commercial cobalt molybdate catalyst. The formation sequence of tetrahydrothiophene desulfurization products was monitored with submilli-second time resolution using the temporal analysis of products (TAP) transient microreactor technique. The TAP experiments showed that butene and were the only hydrocarbon desulfurization products formed, although rapid dehydrogenation to thiophene was also observed. The exceptional time resolution of the TAP spectrometer provided evidence that the butene formed could not be accounted for by a mechanism involving butadiene hydrogenation. The results suggested a desulfurization mechanism for tetrahydrothiophene wherein C{sub 4} hydrocarbon formation proceeds via a surface butene thiolate intermediate produced by a single {beta}-hydride elimination of the intermediate, while rapid C-S bond hydrogenolysis involving surface hydrogen is responsible for butene formation.

Adenocarcinoma de colo uterino com disseminação linfática apresentando-se como carcinoma en cuirasse da vulva: relato de caso.  

PubMed

We report the case of a patient with carcinoma "en cuirasse" of the vulva. Case report: A female patient presented complaining of inguinal lymphadenopathy. Lymph node excision, immunohistochemistry analyses, and further exams showed the presence of cervical adenocarcinoma. The cancer was surgically removed and the patient was treated with radiotherapy and chemotherapy with a good initial response. Some months later she presented with intense edema of the lower limbs, hardening and thickening of the labia majora, and pelvic and genital ulceration. A cutaneous biopsy with subsequent immunohistochemical staining showed lymphatic dissemination of adenocarcinoma to the vulva. Discussion: Carcinoma "en cuirasse" is a rare presentation of cutaneous metastasis in which the affected skin shows hardening and induration, acquiring a sclerodermoid appearance. This is, to the best of our knowledge, the first report in Brazil of carcinoma "en cuirasse" of the vulva associated with cervical adenocarcinoma. PMID:24852775

Estadísticas de visitas en portales web institucionales como indicador de respuesta del público a propuestas de divulgación  

NASA Astrophysics Data System (ADS)

The presence of institutions on the internet is nowadays very important to strenghten communication channels, both internal and with the general public. The Córdoba Observatory has several web portals, including the official web page, a blog and presence on several social networks. These are one of the fundamental pillars for outreach activities, and serve as communication channel for events and scientific, academic, and outreach news. They are also a source of information for the staff, as well as data related to the Observatory internal organization and scientific production. Several statistical studies are presented, based on data taken from the visits to the official web pages. I comment on some aspects of the role of web pages as a source of consultation and as a quick response to information needs. FULL TEXT IN SPANISH

Ensino de astronomia no 1o. e 2o. ciclos do nível fundamental e na educação de jovens e adultos: exemplos e discussões  

NASA Astrophysics Data System (ADS)

Tem-se constatado uma preocupante carência no ensino de astronomia nos diversos níveis de escolaridade. Neste trabalho discutimos várias práticas didático-pedagógicas que vimos desenvolvendo para crianças, jovens e adultos em processo de alfabetização, visando contribuir para reparar aquela carência. Propomos uma metodologia que incorpora as recentes exigências das políticas públicas educacionais, estimula o desenvolvimento de textos e materiais instrucionais, é compatível com a realidade desse público e é adaptável às respectivas faixas etárias. A observação do céu sempre esteve presente na vida de nossos antepassados, dando suporte à compreensão do ser humano como integrante da natureza. Visamos com este trabalho suprir a deficiência encontrada para se tratar a relação do ser humano com o céu, no ambiente escolar. Os resultados são animadores e envolvem práticas e textos que desenvolvemos e atividades realizadas pelos alunos. No primeiro grupo destacamos o desenvolvimento de várias práticas: "viagem aos planetas" (construímos o "foguete", os planetas em escala, contamos história e redigimos texto de orientação para os professores); "gnômon humano" (os próprios corpos dos alunos são usados para registrar o movimento aparente do Sol); "crateras da Lua" (concretização de "meteoritos" e "solo lunar" de gesso e exploração da relação entre energia cinética do bólido e tamanho da cratera formada); etc. No segundo grupo, produções de desenhos e redações e discussões dos alunos após a realização de cada prática, revelam que estas têm se mostrado muito eficientes, tanto para estimular a imaginação e a fantasia dos envolvidos, como para trabalhar-se habilidades, competências e conteúdos relacionados à astronomia, segundo uma perspectiva interdisciplinar contextualizada.

Ensino de astronomia e óptica: é possível fazê-lo de forma contextualizada no nível médio?  

NASA Astrophysics Data System (ADS)

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)

Uma Visão do Universo Segundo um Grupo de Alunos do Ensino Médio de São Paulo  

NASA Astrophysics Data System (ADS)

A astronomia, embora seja uma ciência popular, com inúmeras descobertas de interesse público, ainda é apresentada desconsiderando-se os aspectos históricos e científicos relacionados ao seu desenvolvimento, sendo geralmente veiculada nos meios de comunicação de maneira pouco esclarecedora e não raro com imprecisões. Neste trabalho analisou-se a concepção de um grupo de estudantes de Ensino Médio sobre conceitos de astronomia, visando identificar sua visão de mundo a respeito do Universo, envolvendo idéias sobre espaço e tempo. Para issso, foi aplicado um questionário em três escolas da grande São Paulo em um espaço amostral de 270 alunos. Constatou-se que, embora o ensino de astronomia esteja previsto nos PCNEM, os resultados obtidos na pesquisa mostram que há grande deficiência no conhecimento dos temas investigados. Nesse sentido, verificou-se que apenas 20% dos alunos eram capazes de relacionar a sucessão das semanas com as fases da lua, enquanto 28% associaram as estações do ano à inclinação do eixo de rotação da Terra. Por outro lado, somente 23% dos alunos tinham noções das distâncias entre os objetos celestes próximos da Terra e 56% conseguiram relacionar o Big Bang com a origem do Universo. Finalmente, constatou-se que 37% reconheciam o ano-luz como uma unidade de distância e 60% reconheciam o Sol como sendo uma estrela. Apesar de 60% dos alunos indicarem que a escola é a principal fonte para aquisição dos conhecimentos de astronomia, conclui-se que seus conceitos nessa área ainda são inadequados, havendo necessidade de ampliação e aprimoramento da abordagem desses conteúdos nos ambientes escolares.

Structural and kinetic study of CoMo/. gamma. Al/sub 2/O/sub 3/ hydrodesulfurization catalyst using EXAFS and XANES  

SciTech Connect

In situ Extended X-ray Absorption Fine Structure (EXAFS) and X-ray Absorption Near Edge (XANES) spectroscopies were combined in a study designed to elucidate the molecular structure of molybdenum in CoMo/..gamma..Al/sub 2/O/sub 3/ hydrodesulfurization catalysts. This structure was related to catalytic activity using a model thiophene hydrodesulfurization reaction. Oxide CoMo/..gamma..Al/sub 2/O/sub 3/ was found to consist of tetrahedrally coordinated molybdenum with two or three short Mo = O bonds and one or two oxide ligands with longer Mo-O distances. The catalyst reacts with H/sub 2/S at 25 C with terminal Mo = O species being replaced by sulfur ligands. As the sulfiding temperature is increased, oxysulfides are replaced with a MoS/sub 2/-like phase. No evidence was found of oxysulfides at sulfiding temperatures in excess of 200 C. The first shell sulfur and second shell molybdenum coordination numbers were observed to increase linearly with sulfiding temperature, as was the present MoS/sub 2/-like phase. The MoS/sub 2/-like phase is remarkably similar to MoS/sub 2/, but has a Mo-S coordination number of only four. The second shell coordination is also lower, with only three molybdenum neighbors at 3.16 A. Sulfiding is about 90% complete after two hours at 400 C, with only minor change after 24 hours of sulfiding. This information is consistent with a structural model consisting of small MoS/sub 2/ crystallites of c.a. 10 A if the perimeter molybdenums are considered to have lost labile sulfur. Kinetic EXAFS, XANES and sulfur uptake measurements were made in situ during catalyst sulfiding and HDS. These measurements showed that at high temperature (400 C) the rate of sulfur adsorption onto the catalyst limits the rate of reaction between surface sulfur and molybdenum.

A Mo-K edge XAFS study of the metal sulfide-support interaction in (Co)Mo supported alumina and titania catalysts  

SciTech Connect

The metal-support interaction in oxidic and sulfided (Co)Mo/Al{sub 2}O{sub 3} and (Co)Mo/TiO{sub 2} catalysts has been studied with X-ray absorption spectroscopy. Analysis of the oxidic catalysts showed that on both Mo/Al{sub 2}O{sub 3} and Mo/TiO{sub 2} the molybdenum oxide particles possess a highly distorted octahedral structure with Mo-O distances ranging from 1.71 {Angstrom} to 1.94 {Angstrom}. The second shell Mo-Mo coordination number of less than 1.0 indicated that the size of the molybdenum oxide particles is very small. Upon addition of Co the particle size is increased to approximately four Mo atoms per particle. EXAFS data analysis showed the presence of second shell Al and Ti neighbours indicating a linkage of the molybdenum oxide particles to the support via Mo-O-X (X = Al or Ti) bonds. Upon sulfidation of the oxidic catalysts small MOS{sub 2} particles are formed with second shell Mo-Mo coordination numbers ranging from 0.8 to 3.9. {Angstrom} Mo-O contribution at 2.0 {Angstrom} was found in the first coordination shell of Mo in the sulfided catalysts. Since the coordination number of this Mo-O contribution correlated with the MOS{sub 2} particle size, deduced from the second shell Mo-Mo coordination number, this Mo-O contribution was assigned as an interfacial Mo-O{sub support} linkage. This Mo-O{sub support} linkage stabilizes; the small MOS{sub 2} particles and prevents them from sintering. It is proposed that the activity of these catalysts can be controlled by optimising the molybdenum sulfide-support interaction, which consists of the observed MO-O{sub support} bonds. 56 refs., 11 figs., 6 tabs.

Diferentes Metodologias Aplicadas ao Ensino de Astronomia  

NASA Astrophysics Data System (ADS)

Espera-se que o educando ao final da educação básica, adquira uma compreensão atualizada das hipóteses, modelos e formas de investigação sobre a origem e evolução do Universo em que vive. O presente trabalho tem como principal objetivo compreender dentre três práticas pedagógicas adotadas no Ensino de Astronomia, na terceira série do Ensino Médio, da Escola Estadual Colônia dos Pescadores, qual melhor cumpre o papel de formação e aprendizagem para vida. A pesquisa preliminar foi através de um questionário onde o intuito foi diagnosticar o conhecimento já existente acerca do tema em questão. O questionário é composto de vinte questões dissertativas e objetivas, onde os educandos das três turmas envolvidas o responderam. Este trabalho utiliza as seguintes metodologias: a tradicional, onde o professor é um repassador de informações, fazendo uso exclusivo de lousa e giz; a segunda também de forma tradicional, porém com auxílio de multimídia para desenvolvimento das aulas e aterceira sob forma de seminários, elaborados e apresentados pelos educandos, no qual o educador faz apenas as intervenções necessárias. Ao final do trabalho os alunos responderão novamente o questionário inicial para diagnosticar dentre as três metodologias utilizadas qual apresentou melhor resultado. Os resultados preliminares obtidos, já podem ser observados e, dos 119 alunos entrevistados, as respostas obtidas são as mais diversas e evidenciam que a grande maioria nunca teve em sua vida escolar o tema Astronomia. Ao serem questionados se já haviam estudado Astronomia as respostas foram: turma A: sim 43%; turma B: sim: 21%; turma C: sim: 24%. Porém quando questionados a respeito do significado de Astronomia observou-se que: turma A: 100% de acertos; turma B: 64% acertos; turma C: 84% de acertos, demonstrando claramente a aprendizagem em diferentes esferas, não dependendo unicamente da escola. Até o presente momento, verificou-se que há interesse em estudar o tema Astronom! ia entre os educandos.

Reconstruction of historical atmospheric deposition of DDT in the Zempoala Lagoon, in the center of Mexico [Reconstruccio??n de la deposicio??n atmosfe??rica histo??rica de DDT en la laguna de Zempoala en el centro de Me??xico  

USGS Publications Warehouse

Historical trend in deposition of DDT and its metabolites has been reconstructed by analyzing sediment cores of the Zempoala Lagoon, in the center of Mexico. The small watershed of this mountain lagoon is closed, and it is located between 2.800 and 3.700 masl. It is neither affected by agriculture nor by permanent populations. The Zempoala Lagoon has an average depth of 3.9 m and a maximum depth of 8.8 m. Sediments were extracted with a core sampler and analyzed by isotope methods (137Cs and 210Pb) for dating. Average sedimentation rate was determined in 0.129 g cm-2 yr1, corresponding to a maximum age of the 44 cm core of approximately 60 years. The first presence of total-DDT occurs in a depth between 28 and 32 cm of the sediment profile, corresponding to the 1960's, with a concentration of 5.3 ??g kg-1. The maximum concentration of total-DDT (13.0 ??g kg-1) occurs in sediment layers representing the late 1970's and beginning 1980's. More recently the concentration decreases towards the present concentration of 1.6 ??g kg-1. This concentration is below most DDT levels reported in recent sediment studies in the USA. The results indicate that the Zempoala Lagoon represents a natural recipient for studies of the reconstruction of historical trends of atmospheric contaminant deposition in this region. The limitations of the methodology applied, due to the influence of biodegradation on the definition of correct historical concentrations of DDT depositions, are demonstrated.

Se presentan y discuten resultados obtenidos en el CASLEO y en el Observatorio de Las Campanas de dos cúmulos abiertos compactos con apariencia globular: Westerlund1 (BH197), ubicado en dirección hacia el centro galáctico, y Westerlund2. A partir de espectroscopía CCD integrada de ambos e imágenes CCD en las bandas VI obtenidas para el primero de ellos, se derivan sus parámetros fundamentales y se examinan sus apariencias estructurales. Se encuentra que Westerlund1 es un cúmulo joven (7 ± 3 millones de años), ubicado sobre el plano galáctico a 1.0 ± 0.4 kpc del sol, en una región caracterizada por una absorción excepcionalmente elevada (Av~=13.0 mag), en tanto que Westerlund2 es también un cúmulo joven (4-6 millones de años) ubicado sobre el plano, en una región afectada por una absorción menor (Av~=5.7 mag). Desde el punto de vista estructural, Westerlund 1 se presenta como uno de los pocos cúmulos abiertos jóvenes de la Galaxia con apariencia tipicamente globular, en contraste con los cúmulos azules de las Nubes de Magallanes en los cuales la apariencia globular constituye un fenómeno común. Westerlund2, aunque menos rico en estrellas, puede también ser incluído dentro de esta interesante clase de objetos.

Validating growth and development of a seabird as an indicator of food availability: Captive-reared Caspian Tern chicks fed ad libitum and restricted diets [La validaci??n del crecimiento y desarrollo de un ave marina como un indicador de la disponibilidad de comida: pichones de Hydrogprogne caspia criados en cautiverio y alimentados ad libitum y dietas restringidas  

USGS Publications Warehouse

For seabirds raising young under conditions of limited food availability, reducing chick provisioning and chick growth rates are the primary means available to avoid abandonment of a breeding effort. For most seabirds, however, baseline data characterizing chick growth and development under known feeding conditions are unavailable, so it is difficult to evaluate chick nutritional status as it relates to foraging conditions near breeding colonies. To address this need, we examined the growth and development of young Caspian Terns (Hydroprogne caspia), a cosmopolitan, generalist piscivore, reared in captivity and fed ad libitum and restricted (ca. one-third lower caloric intake) diets. Ad libitum-fed chicks grew at similar rates and achieved a similar size at fledging as previously documented for chicks in the wild and had energetic demands that closely matched allometric predictions. We identified three general characteristics of food-restricted Caspian Tern chicks compared to ad libitum chicks: (1) lower age-specific body mass, (2) lower age-specific skeletal and feather size, such as wing chord length, and (3) heightened levels of corticosterone in blood, both for baseline levels and in response to acute stress. Effects of diet restriction on feather growth (10-11% slower growth in diet-restricted chicks) were less pronounced than effects on structural growth (37-52% slower growth) and body mass (24% lower at fledging age), apparently due to preferential allocation of food resources to maintain plumage growth. Our results suggest that measurements of chick body mass and feather development (e.g., wing chord or primary length) or measurement of corticosterone levels in the blood would allow useful evaluation of the nutritional status of chicks reared in the wild and of food availability in the foraging range of adults. Such evaluations could also inform demography studies (e.g., predict future recruitment) and assist in evaluating designated piscivorous waterbird conservation (colony) sites. ?? 2011 The Authors.

Moléculas orgánicas no-rígidas  

NASA Astrophysics Data System (ADS)

Se destaca la importancia del estudio espectroscópico ab initio de una serie de moléculas no-rígidas detectadas en el medio interestelar (acetona, dimetil-eter, etanol, metanol, metilamina, ldots), así como los últimos avances del desarrollo de la metodología para el tratamiento teórico de estas especies. Se describe, a modo de ejemplo, el análisis del espectro roto-torsional de la molécula de glicoaldehido que ha sido recientemente detectada en el centro Galáctico Sagitario B2 (N) [1]. Esta especie presenta dos movimientos de gran amplitud que interaccionan, descansan en el Infrarrojo Lejano y le confiere propiedades no-rígidas. La molécula puede existir en posiciones cis y trans y presenta cinco confórmeros estables, tres de simetría Cs (I, II y IV) y un doble mínimo trans de simetría C1 (III) . La conformación favorita, I, presenta simetría Cs y se estabiliza por la formación de un puente de hidrógeno entre los grupos OH y C=O. Los mínimos secundarios II, III, y IV se han determinado a 1278.2 cm-1 (trans, Cs), 1298.8 cm-1 (trans, C1) y 1865.2 cm-1 (cis, Cs) con cálculos MP4/cc-pVQZ que incluyen sustituciones triples. Para determinar que vibraciones interaccionan con las torsiones, se ha realizado un análisis armónico en los mínimos. Las frecuencias fundamentales armónicas correspondientes al mínimo I se han calculado en 213.4 cm-1 (torsión C-C) y 425.7 cm-1 (torsión OH). Es de esperar que tan sólo dos vibraciones, la flexión del grupo C-C-O y el aleteo del hidrógeno del grupo aldehídico puedan desplazar el espectro torsional de la molécula aislada. Para determinar el espectro torsional, se ha determinado la superficie de potencial en dos dimensiones mediante el cálculo ab initio de las geometrías y energías de 74 conformaciones seleccionadas. Estas últimas se han ajustado a un doble serie de Fourier. A partir de la PES y de los parámetros cinéticos del Hamiltoniano vibracional se han obtenido frecuencias e intensidades. Las frecuencias fundamentales se han calculado en 208.0 cm-1 (torsión C-C) y 349.9 cm-1 (torsión OH). Se discute el método de cálculo que se ha empleado para la clasificación de los niveles. Los niveles rotacionales se han determinado empleando el método desarrollado para el estudio del ácido acético [2]. Se emplean la base de funciones rotacionales de [3]. A partir de los niveles se han determinado las constantes rotacionales y las constantes de distorsión centrífuga que se comparan con las experimentales de Herbst et al [3].

Invertebrate fauna associated with Torpedograss, Panicum repens (Cyperales: Poaceae), in Lake Okeechobee, Florida, and prospects for biological control  

SciTech Connect

Torpedograss, Panicum repens L., is an adventive, rhizomatous grass species that has become an invasive weed of terrestrial, wetland, and aquatic environments in tropical and subtropical regions worldwide. Until recently, strategies for controlling torpedograss in the USA have focused almost exclusively on mechanical and chemical methods, either alone or in combination, with varied results. A survey of the arthropods and nematodes currently associated with the plant in Lake Okeechobee, Florida, was conducted as part of a feasibility study to determine whether torpedograss is an appropriate target for a classical biological control program. Overall, approximately 4,000 arthropods and 400 nematode specimens were collected. Sweep, clipped vegetation, and soil core samples were dominated by representatives of the arthropod orders Hemiptera, Hymenoptera, Diptera, and Acari. Lesion nematodes of the genus Pratylenchus were commonly associated with the roots of torpedograss. None of the organisms collected were torpedograss specialists. Although classical biological control of torpedograss is feasible based on the extent of the infestation, economic losses, resistance to conventional controls, and the report of a potentially host specific natural enemy in India, the botanical position of this grass weed will require a formal risk assessment before proceeding with a classical biological control program. (author) [Spanish] La conota, Panicum repens L., es una especie foranea de pasto que produce rizomas que ha convertido en ser una maleza invasora de ambientes terrestres, pantanosos y acuaticos en regiones tropicales y subtropicales en todo el mundo. Hasta hace un tiempo reciente, las estrategias para controlar conota en los EEUU eran enfocadas casi exclusivamente en los metodos mecanicos y quimicos, solos o en combinacion, con resultados variables. Un muestreo de los artropodos y nematodos asociados corrientemente con esta planta en el Lago de Okeechobee, Florida, fue realizado como parte de un estudio de factibilidad para determinar si conota es una candidata apropiada para un programa de control biologico clasico. En general, especimenes de aproximadamente unos 4,000 artropodos y unos 400 nematodos fueron recolectados. Muestras recolectadas pasando una red sobre vegetacion mezclada, cortando la vegetacion y tomando centros del suelo fueron dominados por representantes de artropodos de los ordenes de Hemiptera, Hymenoptera, Diptera, y Acari. Nematodos en el genero Pratylenchus, que causan lesiones sobre tejido, fueron asociados regularmente con las raices de conota. Ninguno de los organismos recolectados eran especialistas sobre conota. Aunque el control biologico clasico de la conota es factible basado sobre la magnitud de la infestacion, las perdidas economicas, la resistencia hacia los metodos de control convencionales y el informe en la India de un posible enemigo natural especifico a esta planta, la posicion botanica de este pasto maleza requiere una evaluacion de riesgo economico formal antes de continuar con un programa de control biologico clasico.

Monitoring artificially stimulated fluid movement in the Cretaceous Dakota aquifer, western Kansas  

NASA Astrophysics Data System (ADS)

Aquifer properties can be evaluated by monitoring artificially stimulated fluid movements between wells, if the fluid is heated. Changes in the temperature profile recorded in observation wells indicate the flow path of the heated fluid, which in effect acts as a tracer. A fluid-flow experiment in the Cretaceous Dakota Formation at the Hodgeman County site, west-central Kansas, demonstrated the advantage of using the distributed optical-fiber temperature sensing method for monitoring transient temperature conditions in this hydrological application. The fluid flow in the aquifer was increased by producing water from a pumping well and injecting heated water in an injection well 13 m (43 ft) distant from the pumping well. The time-temperature series data obtained and compared with results from previous pumping tests point to interwell heterogeneity of the aquifer and to a zone in the sandstone aquifer of high hydraulic conductivity. However, the experiment would have allowed further clarification of aquifer heterogeneity and thermal properties if at least one observation well had been present between the injection and production wells. Résumé. Les caractéristiques d'un aquifère peuvent être évaluées en effectuant un suivi des mouvements du fluide stimulés artificiellement entre des puits, si le fluide est chauffé. Les variations de profils de température enregistrés dans les puits d'observation donnent des informations sur les directions d'écoulement du fluide chauffé, qui en fait se comporte comme un traceur. Réalisée dans la formation crétacée de Dakota, sur le site du Comté de Hodgeman (centre-ouest du Kansas), une expérience a démontré l'intérêt d'utiliser la méthode de détection distribuée de température par fibres optiques pour suivre les variations de température dans cette application hydrologique. L'écoulement du fluide dans l'aquifère a été favorisé en extrayant de l'eau par pompage et en injectant de l'eau chaude dans un puits d'injection distant de 13 m du puits de pompage. La chronique de température obtenue et comparée aux résultats d'essais de pompage précédents fait apparaître l'hétérogénéité de l'aquifère entre les puits et l'existence d'une zone de forte conductivité hydraulique dans l'aquifère de grès. Toutefois, l'expérience aurait fourni des éclaircissements supplémentaires sur l'hétérogénéité de l'aquifère et sur ses propriétés thermiques si au moins un puits d'observation avait été placé entre le puits d'injection et le puits de pompage. Resumen. Se puede evaluar las propiedades de un acuífero mediante la observación del movimiento de un fluido, calentado artificialmente, entre pozos. Los cambios registrados en el perfil de temperatura de los pozos de observación indican la trayectoria del fluido calentado, el cual actúa como un trazador. Un experimento de este tipo que se realizó en la formación cretácica de Dakota, en el condado de Hodgeman (porción occidental del centro de Kansas, Estados Unidos de América), demostró la ventaja de utilizar el método del sensor de temperatura con fibra óptica distribuída para medir condiciones transitorias de temperatura en esta aplicación hidrológica. El flujo del fluido en el acuífero aumentó con el bombeo de un pozo y la inyección de agua caliente en otro sondeo, que distaba 13 m (43 pies) del primero. Las series de temperatura obtenidas y comparadas con resultados de ensayos de bombeo previos resaltan la heterogeneidad del acuífero entre ambos pozos, así como la existencia de una zona de elevada conductividad hidráulica en el acuífero de la arenisca. Sin embargo, el experimento habría proporcionado más información sobre la heterogeneidad de la formación y sus propiedades termales si se hubiera dispuesto al menos de un punto de observación entre los pozos de inyección y bombeo.

Copper(II) complexes of a racemic mixture of a chiral nitronyl-nitroxide are characterised. One, A, is a centro-symmetrical species where two enantiomers are coordinated to a metal centre. The second, B, is a 1D compound comprising bridging ligands through the oxyl and pyridyl donor sites. One observes that, although the crystals are racemic, within a chain, all ligands and metal centres

Detection of number of sources via exploitation of centrosymmetry property  

Microsoft Academic Search

Forward\\/backward (FB) averaging is a technique which can be employed in sensor array signal processing for exploiting a so-called centro-symmetry property of the signal subspace to improve parameter estimation accuracy. Although FB averaging effectively doubles the number of data samples, it also introduces correlation among these data vectors. This correlation complicates not only the performance analysis, but also the detection

Traumatic tears of the tela chorioidea: a hitherto unrecognized cause of post-traumatic hydrocephalus.  

PubMed

A new and hitherto unrecognized phenomenon of rupture of the tela chorioidea in closed head injury of acceleration-deceleration type is described. It occurs very frequently, especially in association with blows in the centro-axial plane even if the acceleration forces are relatively mild. These tears are regularly followed by intraventricular bleeding which follows the flow of the CSF into the subarachnoid space producing a leptomeningeal reaction with impairment of absorption of CSF and consequent communicating hydrocephalus.

Centromeric Retroelements and Satellites Interact with Maize Kinetochore Protein CENH3  

Microsoft Academic Search

Maize centromeres are composed of CentC tandem repeat arrays, centromeric retrotransposons (CRs), and a variety of other repeats. One particularly well-conserved CR element, CRM, occurs primarily as complete and uninterrupted elements and is interspersed thoroughly with CentC at the light microscopic level. To determine if these major centro- meric DNAs are part of the functional centromere\\/kinetochore complex, we generated antiserum
