NASA Giovanni (Goddard Interactive Online Visualization ANd aNalysis Infrastructure) is a web-based remote sensing and model data visualization and analysis system developed by the Goddard Earth Sciences Data and Information Services Center (GES DISC). This web-based tool facilitates data discovery, exploration and analysis of large amount of global and regional data sets, covering atmospheric dynamics, atmospheric chemistry, hydrology, oceanographic, and land surface. Data analysis functions include Lat-Lon map, time series, scatter plot, correlation map, difference, cross-section, vertical profile, and animation etc. Visualization options enable comparisons of multiple variables and easier refinement. Recently, new features have been developed, such as interactive scatter plots and maps. The performance is also being improved, in some cases by an order of magnitude for certain analysis functions with optimized software. We are working toward merging current Giovanni portals into a single omnibus portal with all variables in one (virtual) location to help users find a variable easily and enhance the intercomparison capability

New features and capabilities in the newly released GIOVANNI allow exploring GPM IMERG (Integrated Multi-satelliE Retrievals for GPM) Early, Late and Final Run global half-hourly and monthly precipitation products as well as other precipitation products distributed by the GES DISC such as TRMM Multi-Satellite Precipitation Analysis (TMPA), MERRA (Modern Era Retrospective-Analysis for Research and Applications), NLDAS (North American Land Data Assimilation Systems), GLDAS (Global Land Data Assimilation Systems), etc. GIOVANNI is a web-based tool developed by the GES DISC (Goddard Earth Sciences and Data Information Services Center) to visualize and analyze Earth science data without having to download data and software. The new interface in GIOVANNI allows searching and filtering precipitation products from different NASA missions and projects and expands the capabilities to inter-compare different precipitation products in one interface. Knowing differences in precipitation products is important to identify issues in retrieval algorithms, biases, uncertainties, etc. Due to different formats, data structures, units and so on, it is not easy to inter-compare precipitation products. Newly added features and capabilities (unit conversion, regridding, etc.) in GIOVANNI make inter-comparisons possible. In this presentation, we will describe these new features and capabilities along with examples.

Giovanni is a data exploration and visualization tool at the NASA Goddard Earth Sciences Data Information Services Center (GES DISC). It has been around in one form or another for more than 15 years. Giovanni calculates simple statistics and produces 22 different visualizations for more than 1600 geophysical parameters from more than 90 satellite and model products. Giovanni relies on external data format standards to ensure interoperability, including the NetCDF CF Metadata Conventions. Unfortunately, these standards were insufficient to make Giovanni's internal data representation truly simple to use. Finding and working with dimensions can be convoluted with the CF Conventions. Furthermore, the CF Conventions are silent on machine-friendly descriptive metadata such as the parameter's source product and product version. In order to simplify analyzing disparate earth science data parameters in a unified way, we developed Giovanni's internal standard. First, the format standardizes parameter dimensions and variables so they can be easily found. Second, the format adds all the machine-friendly metadata Giovanni needs to present our parameters to users in a consistent and clear manner. At a glance, users can grasp all the pertinent information about parameters both during parameter selection and after visualization.

Collecting data and understanding data structures traditionally are the first steps that a user must take, before the core investigation can begin. This is a time-consuming and challenging task, especially when science objectives require users to deal with large multi-sensor data that are usually in different formats and internal structures. The Goddard Earth Sciences Data and Information Services Center (GES DISC) has created the GES DISC Interactive Online Visualization and ANalysis Infrastructure, Giovanni, to enable Web-based visualization and analysis of satellite remotely sensed meteorological, oceanographic, and hydrologic data sets, without users having to download data. The current operational Giovanni interfaces provide the capability to process a number of important satellite measurements, such as (1) ozone and other trace gases from TOMS, OMI, HALOE, and MLS; (2) air temperature, water vapor, and geopotential height from AIRS; (3) aerosols from MODIS TerrdAqua, and GOCART model; (4) precipitation from TRMM and ground measurements; (5) chlorophyll and other ocean color products from SeaWiFS and MODIS Aqua; and (6) sea surface temperature from MODIS Aqua. Depending on the input data structure, the system provides simple statistical analysis and creates time-averaged area plot, area-averaged time series, animations, Hovmoller latitude vs. time and longitude vs. time plots, as well as vertical profiles. The inter-comparison interfaces allow a user to compare observations from different instruments, to conduct anomaly analysis, and to study basic relationships between physical parameters. Giovanni handles data with different temporal and spatial resolutions and, thus, enables both regional and global long-term climate research and short-term special events investigation, as well as data validations and assessments. Because of its simplicity of usage, Giovanni is powerful and versatile, able to assist a wide range of users, from the discipline scientists

Using NASA's Giovanni Web Portal to Access and Visualize Satellite-Based Earth Science Data in the Classroom

One of the biggest obstacles for the average Earth science student today is locating and obtaining satellite- based remote sensing datasets in a format that is accessible and optimal for their data analysis needs. At the Goddard Earth Sciences Data and Information Services Center (GES-DISC) alone, on the order of hundreds of Terabytes of data are available for distribution to scientists, students and the general public. The single biggest and time-consuming hurdle for most students when they begin their study of the various datasets is how to slog through this mountain of data to arrive at a properly sub-setted and manageable dataset to answer their science question(s). The GES DISC provides a number of tools for data access and visualization, including the Google-like Mirador search engine and the powerful GES-DISC Interactive Online Visualization ANd aNalysis Infrastructure (Giovanni) web interface. Giovanni provides a simple way to visualize, analyze and access vast amounts of satellite-based Earth science data. Giovanni's features and practical examples of its use will be demonstrated, with an emphasis on how satellite remote sensing can help students understand recent events in the atmosphere and biosphere. Giovanni is actually a series of sixteen similar web-based data interfaces, each of which covers a single satellite dataset (such as TRMM, TOMS, OMI, AIRS, MLS, HALOE, etc.) or a group of related datasets (such as MODIS and MISR for aerosols, SeaWIFS and MODIS for ocean color, and the suite of A-Train observations co-located along the CloudSat orbital path). Recently, ground-based datasets have been included in Giovanni, including the Northern Eurasian Earth Science Partnership Initiative (NEESPI), and EPA fine particulate matter (PM2.5) for air quality. Model data such as the Goddard GOCART model and MERRA meteorological reanalyses (in process) are being increasingly incorporated into Giovanni to facilitate model- data intercomparison.

Venetian physician Giovanni Domenico Santorini is revered as one of the most industrious and thorough anatomists of the eighteenth century. After receiving his medical degree in Pisa, Santorini worked as a physician and professor of anatomy and obstetrics in Venice. Of interest, he was a student of Malpighi while in Pisa. He quickly established himself as a dynamic lecturer and meticulous dissector. Santorini's anatomical observations include the prostatic venous plexus, accessory pancreatic duct, corniculate cartilage, parietal emissary veins, the risorius muscle, and many other structures. In addition to the detailed descriptions of these structures, he also produced copper plates and illustrations that are revered as "masterpieces" of that era. Santorini published Observationes anatomicae (Anatomical observations) in 1724, however his primary work, which included the description and anatomical drawings of the accessory pancreatic duct, was not published until thirty-eight years after his death. This posthumous release of Jo. Dominici Santorini anatomici summi septedecim tabulae [Giovanni Domenici Santorini, the excellent anatomist's seventeen drawings] was accomplished by Giambattista Morgagni and his disciple, Michael Girardi in 1775. Giovanni Santorini's assiduous dissections have significantly enhanced our knowledge of human anatomy and his work has been immortalized with several anatomical eponyms.

There are many existing satellite soil moisture algorithms and their derived data products, but there is no simple way for a user to inter-compare the products or analyze them together with other related data. An environment that facilitates such inter-comparison and analysis would be useful for validation of satellite soil moisture retrievals against in situ data and for determining the relationships between different soil moisture products. As part of the NASA Giovanni (Geospatial Interactive Online Visualization ANd aNalysis Infrastructure) family of portals, which has provided users worldwide with a simple but powerful way to explore NASA data, a beta prototype Giovanni Inter-comparison of Soil Moisture Products portal has been developed. A number of soil moisture data products are currently included in the prototype portal. More will be added, based on user requirements and feedback and as resources become available. Two application examples for the portal are provided. The NASA Giovanni Soil Moisture portal is versatile and extensible, with many possible uses, for research and applications, as well as for the education community.

The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) has taken a major step addressing the challenge of using archived Earth Observing System (EOS) data for regional or global studies by developing an infrastructure with a World Wide Web interface which allows online, interactive, data analysis: the GES DISC Interactive Online Visualization and ANalysis Infrastructure, or "Giovanni." Giovanni provides a data analysis environment that is largely independent of underlying data file format. The Ocean Color Time-Series Project has created an initial implementation of Giovanni using monthly Standard Mapped Image (SMI) data products from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) mission. Giovanni users select geophysical parameters, and the geographical region and time period of interest. The system rapidly generates a graphical or ASCII numerical data output. Currently available output options are: Area plot (averaged or accumulated over any available data period for any rectangular area); Time plot (time series averaged over any rectangular area); Hovmeller plots (image view of any longitude-time and latitude-time cross sections); ASCII output for all plot types; and area plot animations. Future plans include correlation plots, output formats compatible with Geographical Information Systems (GIs), and higher temporal resolution data. The Ocean Color Time-Series Project will produce sensor-independent ocean color data beginning with the Coastal Zone Color Scanner (CZCS) mission and extending through SeaWiFS and Moderate Resolution Imaging Spectroradiometer (MODIS) data sets, and will enable incorporation of Visible/lnfrared Imaging Radiometer Suite (VIIRS) data, which will be added to Giovanni. The first phase of Giovanni will also include tutorials demonstrating the use of Giovanni and collaborative assistance in the development of research projects using the SeaWiFS and Ocean Color Time-Series Project data in the online Laboratory

The Atmospheric Infrared Sounder (AIRS) mission began with the launch of Aqua in 2002. Over 15 years of AIRS products have been used by the climate research and application communities. The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC), in collaboration with NASA Sounder Team at JPL, provides processing, archiving, and distribution services for NASA sounders: the present Aqua AIRS mission and the succeeding Suomi National Polar-Orbiting Partnership (SNPP) Cross-track Infrared Sounder (CrIS) mission. We generated a Multi-year Monthly Mean and Anomaly product using 14 years of AIRS standard monthly product. The product includes Air Temperature at the Surface and Surface Skin Temperature, both in Ascending/Daytime and Descending/Nighttime mode. The temperature variables and their anomalies are deployed to Giovanni, a Web-based application developed by the GES DISC. Giovanni provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data without having to download the data. It is also a powerful tool that stakeholders can use for decision support in planning and preparing for increased climate variability. In this presentation, we demonstrate the functions in Giovanni with use cases employing AIRS Multi-year Monthly Mean and Anomaly variables.

Performance Comparison of Big Data Analytics With NEXUS and Giovanni

NEXUS is an emerging data-intensive analysis framework developed with a new approach for handling science data that enables large-scale data analysis. It is available through open source. We compare performance of NEXUS and Giovanni for 3 statistics algorithms applied to NASA datasets. Giovanni is a statistics web service at NASA Distributed Active Archive Centers (DAACs). NEXUS is a cloud-computing environment developed at JPL and built on Apache Solr, Cassandra, and Spark. We compute global time-averaged map, correlation map, and area-averaged time series. The first two algorithms average over time to produce a value for each pixel in a 2-D map. The third algorithm averages spatially to produce a single value for each time step. This talk is our report on benchmark comparison findings that indicate 15x speedup with NEXUS over Giovanni to compute area-averaged time series of daily precipitation rate for the Tropical Rainfall Measuring Mission (TRMM with 0.25 degree spatial resolution) for the Continental United States over 14 years (2000-2014) with 64-way parallelism and 545 tiles per granule. 16-way parallelism with 16 tiles per granule worked best with NEXUS for computing an 18-year (1998-2015) TRMM daily precipitation global time averaged map (2.5 times speedup) and 18-year global map of correlation between TRMM daily precipitation and TRMM real time daily precipitation (7x speedup). These and other benchmark results will be presented along with key lessons learned in applying the NEXUS tiling approach to big data analytics in the cloud.

Online Time Series Analysis of Land Products over Asia Monsoon Region via Giovanni

Time series analysis is critical to the study of land cover/land use changes and climate. Time series studies at local-to-regional scales require higher spatial resolution, such as 1km or less, data. MODIS land products of 250m to 1km resolution enable such studies. However, such MODIS land data files are distributed in 10ox10o tiles, due to large data volumes. Conducting a time series study requires downloading all tiles that include the study area for the time period of interest, and mosaicking the tiles spatially. This can be an extremely time-consuming process. In support of the Monsoon Asia Integrated Regional Study (MAIRS) program, NASA GES DISC (Goddard Earth Sciences Data and Information Services Center) has processed MODIS land products at 1 km resolution over the Asia monsoon region (0o-60oN, 60o-150oE) with a common data structure and format. The processed data have been integrated into the Giovanni system (Goddard Interactive Online Visualization ANd aNalysis Infrastructure) that enables users to explore, analyze, and download data over an area and time period of interest easily. Currently, the following regional MODIS land products are available in Giovanni: 8-day 1km land surface temperature and active fire, monthly 1km vegetation index, and yearly 0.05o, 500m land cover types. More data will be added in the near future. By combining atmospheric and oceanic data products in the Giovanni system, it is possible to do further analyses of environmental and climate changes associated with the land, ocean, and atmosphere. This presentation demonstrates exploring land products in the Giovanni system with sample case scenarios.

The NASA Giovanni data analysis system has been recognized as a useful tool to access and analyze many different types of remote sensing data. The variety of environmental data types has allowed the use of Giovanni for different application areas, such as agriculture, hydrology, and air quality research. The use of Giovanni for researching connections between public health issues and Earths environment and climate, potentially exacerbated by anthropogenic influence, has been increasingly demonstrated. In this communication, the pertinence of several different data parameters to public health will be described. This communication also provides a case study of the use of remote sensing data from Giovanni in assessing the associations between seasonal influenza and meteorological parameters. In this study, logistic regression was employed with precipitation, temperature and specific humidity as predictors. Specific humidity was found to be associated (p 0.05) with influenza activity in both temperate and tropical climate. In the two temperate locations studied, specific humidity was negatively correlated with influenza; conversely, in the three tropical locations, specific humidity was positively correlated with influenza. Influenza prediction using the regression models showed good agreement with the observed data (correlation coefficient of 0.50.83).

The NASA Goddard Earth Science Data and Information Services Center (GES DISC) is investigating the performance, agility and cost of Cloud computing for GES DISC applications. Giovanni (Geospatial Interactive Online Visualization ANd aNalysis Infrastructure), one of the core applications at the GES DISC for online climate-related Earth science data access, subsetting, analysis, visualization, and downloading, was used to evaluate the feasibility and effort of porting an application to the Amazon Cloud Services platform. The performance and the cost of running Giovanni on the Amazon Cloud were compared to similar parameters for the GES DISC local operational system. A Giovanni Time-Series analysis of aerosol absorption optical depth (388nm) from OMI (Ozone Monitoring Instrument)/Aura was selected for these comparisons. All required data were pre-cached in both the Cloud and local system to avoid data transfer delays. The 3-, 6-, 12-, and 24-month data were used for analysis on the Cloud and local system respectively, and the processing times for the analysis were used to evaluate system performance. To investigate application agility, Giovanni was installed and tested on multiple Cloud platforms. The cost of using a Cloud computing platform mainly consists of: computing, storage, data requests, and data transfer in/out. The Cloud computing cost is calculated based on the hourly rate, and the storage cost is calculated based on the rate of Gigabytes per month. Cost for incoming data transfer is free, and for data transfer out, the cost is based on the rate in Gigabytes. The costs for a local server system consist of buying hardware/software, system maintenance/updating, and operating cost. The results showed that the Cloud platform had a 38% better performance and cost 36% less than the local system. This investigation shows the potential of cloud computing to increase system performance and lower the overall cost of system management.

The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) has been the home of processing, archiving, and distribution services for the Atmospheric Infrared Sounder (AIRS) mission since its launch in 2002 for the global observations of the atmospheric state. Giovanni, a web-based application developed by the GES DISC, provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data without having to download the data. Most important variables, including temperature and humidity profiles, outgoing longwave radiation, cloud properties, and trace gases, from version 6 AIRS product are available on Giovanni. The AIRS is an instrument suite comprised of a hyperspectral infrared instrument AIRS and two multichannel microwave instruments, the Advanced Microwave Sounding Unit (AMSU) and the Humidity Sounder for Brazil (HSB). As the HSB ceased operation in very early stage of AIRS mission, the AIRS project operates two parallel retrieval algorithms: one using both IR and MW measurements (AIRS+AMSU) and the other using only IR measurements (AIRS-only) for the most time of the mission. The AIRS+AMSU product is better and the variables on Giovanni are from it. However, the generation of AIRS+AMSU product has been suspended since the AMSU instrument anomaly occurred in late 2016. To continue exploring up-to-date AIRS observations, the same set of variables from the AIRS-only product are added on Giovanni by the GES DSIC. This will also support the comparison of AIRS-only with AIRS+AMSU retrievals. In the presentation, we will demonstrate the visualization of AIRS-only product and the plots/statistics of comparison with AIRS+AMSU product using Giovanni.

This article highlights important aspects of the biography of Giovanni Berlinguer that led him to become a prominent scientist and political activist. His works were marked by a strong socialist conviction and deep humanism. His contribution to health in Brazil ranged from a vast academic output in the field of public health to an active involvement in the Brazilian Health Movement. His later publications addressing everyday bioethics reveal the common thread that runs through his entire works: the use of science to demonstrate the social determinants of health; the fight against unjust inequality; the defense of life against exploitation; and the struggle to prevent the commoditization of life, the human body, and health care.

The proposed dissemination framework for the YOTC satellite data archive is based on the Giovanni system. Giovanni is a web-based application developed by the NASA Goddard Earth Science (GES) Data and Information Service Center (DISC) that provides a simple and intuitive way to visualize, analyze, and access/download vast amounts of Earth science remote sensing data. A prototype YOTC Giovanni System (hereafter YOTC-GS) is in the process of being developed. YOTC-GS will provide access to level 2 (i.e. swath level data) and/or level 3 (i.e. gridded/mapped data) forms of satellite data, the choice or both depending on what is appropriate and relevant. The former is needed and better suited for detailed process examination, exploiting the highest temporal-spatial resolutions available and comparison to regional cloud-system resolving model / cloud resolving model (CSRM/CRM) model output. The latter is needed and more well suited for examination of phenomena, conditions and processes on large to global scales, and for comparisons to global model analyses, prediction and simulation output.

The demonstration includes the enhanced information for educators developed for the DICCE-G portal. The prototype DICCE Learning Environment (DICCE-LE) for classroom project development will also be demonstrated.

[Petechial typhus in Napoleonic Italy. Scientific debate and the role of Giovanni Rasori].

PubMed

Sabbatani, Sergio

2006-12-01

During the Napoleonic wars, an epidemic recrudescence of petechial typhus was observed throughout Europe. In Italy, the epidemic first broke out in Genoa, in 1799, coming from southern France, during the sieges of the Austro-Hungarian army. Giovanni Rasori, a young Republican physician and man of the sciences, supported the besieged and contributed to defend the city. From the beginning, Rasori identified the cause of the epidemic in petechial typhus, being able to evaluate its clinical presentation, and developed a pathogenetic theory, known as contrastimulus. At that time, this theory obtained some success, though opposed by the academic establishment in Lombardy. In this article, we present the medical and philosophical ideas which, in the period between the 18th and 19th century, pervaded medical Italian culture. Furthermore, a biographic profile of Giovanni Rasori is described, a courageous scientist who did not disdain to take part in political and cultural Italian life during a historical period that was to become important for the future fortunes of Italy.

The electrical induction of seizures with a therapeutic aim began in 1938, but the history of electric currents to relieve mental illness began 2 centuries earlier with the pioneering work of the Italian Giovanni Aldini and the American Benjamin Franklin.These early experiments are described demonstrating that the electrical force encouraged hopeful applications. This history emphasizes the unique contribution in the induction of grand mal seizures as the therapeutic basis rather than the role of electricity alone.

The role of environment and climate in propagating infectious disease has long been recognized since the 5th century. The effect is particularly evident in vector-borne diseases such as malaria where temperature, precipitation and humidity influence the lifecycle of the pathogens and mosquitoes. Likewise, the transmission of respiratory diseases is also often associated with climatic factors. For example, a recent study showed that low humidity and temperature provides efficient condition for seasonal influenza transmission. Understanding of how environment and climate affect infectious diseases would essentially provide guides to prevent and control the spread of disease. Toward this end, our group has developed models for infectious disease risk such as for malaria, dengue and influenza that are driven by climatic and environmental inputs. Results will be presented, especially those that used TRMM data from GIOVANNI.

The multiplicity of Spica's system has been first observed in 1753 by the dominican father Giovanni Battista Audiffredi through a lunar occultation. Audiffredi noted that the emersion's duration from the bright lunar limb was not instantaneous. Nowadays Spica has five known components, four of them have been discovered by occultation. This observation is presented along with a general introduction of lunar occultations, Watts' profiles, Cassini regions and grazes.

Exciting perspectives for Translational Myology in the Abstracts of the 2018Spring PaduaMuscleDays: Giovanni Salviati Memorial – Chapter I – Foreword

Myologists working in Padua (Italy) were able to continue a half-century tradition of studies of skeletal muscles, that started with a research on fever, specifically if and how skeletal muscle contribute to it by burning bacterial toxin. Beside main publications in high-impact-factor journals by Padua myologists, I hope to convince readers (and myself) of the relevance of the editing Basic and Applied Myology (BAM), retitled from 2010 European Journal of Translational Myology (EJTM), of the institution of the Interdepartmental Research Center of Myology of the University of Padova (CIR-Myo), and of a long series of International Conferences organized in Euganei Hills and Padova, that is, the PaduaMuscleDays. The 2018Spring PaduaMuscleDays (2018SpPMD), were held in Euganei Hills and Padua (Italy), in March 14-17, and were dedicated to Giovanni Salviati. The main event of the “Giovanni Salviati Memorial”, was held in the Aula Guariento, Accademia Galileiana di Scienze, Lettere ed Arti of Padua to honor a beloved friend and excellent scientist 20 years after his premature passing. Using the words of Prof. Nicola Rizzuto, we all share his believe that Giovanni “will be remembered not only for his talent and originality as a biochemist, but also for his unassuming and humanistic personality, a rare quality in highly successful people like Giovanni. The best way to remember such a person is to gather pupils and colleagues, who shared with him the same scientific interests and ask them to discuss recent advances in their own fields, just as Giovanni have liked to do”. Since Giovanni’s friends sent many abstracts still influenced by their previous collaboration with him, all the Sessions of the 2018SpPMD reflect both to the research aims of Giovanni Salviati and the traditional topics of the PaduaMuscleDays, that is, basics and applications of physical, molecular and cellular strategies to maintain or recover functions of skeletal muscles.

Giovanni Battista Morgagni is considered the Father of Pathology and contributed much to our early understanding of neuropathology. For example, he introduced the concept that diagnosis, prognosis, and treatment of disease must be based on an exact understanding of the pathologic changes in anatomic structures. Additionally, he contributed to what would become the discipline of neurosurgery and, for example, performed trepanation for head trauma. It is the contributions of such early pioneers as Morgagni that our current understanding of the neurosciences is based.

Giovanni Gribodo (1846-1924) was an Italian civil engineer who described 377 new taxa of Hymenoptera, 199 of which are still valid and in use today, and proposed 6 replacement names. The present catalog provides a brief biography of Gribodo, a bibliography of his 42 publications and a complete list of the taxa proposed by Gribodo. The catalog lists, for all published names, details on the type series, type locality and collector, present status based on literature, all data labels, relevant references and remarks. A gazetteer of type-localities, a systematical list of Genus- and Species-group names, a chronological list of new names proposed by Giovanni Gribodo, with name-bearing types, and a list of Algerian species and varieties are also given. Furthermore, an unpublished manuscript by Gribodo on hymenopterological fauna of Tunisia, still kept at the Civic Museum of Natural History "Giacomo Doria" (Genoa, Italy), is described, and data on the 57 "new" taxa therein listed are reported, discussing their relevance in order to ascertain the original type series of 27 taxa validly published later. Finally, the problem posed by the enigmatic "disappearance" of a large number of Algerian types, already faced by several entomologists in the past, is analyzed, in order to prevent future mistaken designations of lectotypes and neotypes. The following six nomenclatural acts are proposed here by R. Wahis: Hemipepsis sycophanta Gribodo, 1884 = Hemipepsis bellicosa (Smith, 1873) new synonym; Anospilus sulcithorax (Gribodo, 1924) new combination; Auplopus validus (Gribodo, 1884) new combination; Dichragenia quartinae (Gribodo, 1884) new combination; Diplonyx caesar (Gribobo, 1894) new combination; Paracyphononyx melanicrus Gribodo, 1884 status revalidated (resurrected from synonymy with Pompilus ruficrus Klug, 1834). The following four nomenclatural acts are proposed by F. Penati: Parachrysis Gribodo, 1879 [subgenus of Chrysis Linnaeus] = Chrysis Linnaeus, 1760 new synonym

Spatial and Temporal Coherence of SeaWiFS Chlorophyll Concentration Anomalies in the North Atlantic Bloom (1998-2005) Examined with Giovanni

2006-01-01

The availability of climatological chlorophyll-a concentration data products from the SeaWiFS mission spanning the eight-year mission period allowed the creation of a climatological anomaly analysis function in Giovanni, the GES DISC Interactive Online Visualization and ANalysis Infrastructure. This study utilizes the Giovanni anomaly analysis function to examine mesoscale anomalies in the North Atlantic Ocean during the springtime North Atlantic Bloom. This examination indicates that areas exhibiting positive anomalies and areas exhibiting negative anomalies are coherent over significant spatial scales, with relatively abrupt boundaries between areas with positive and negative anomalies. Year-to-year variability in anomaly "intensity" can be caused by either variability in the temporal occurrence of the bloom peak or by variability in the peak chlorophyll concentration in a particular area. The study will also discuss the feasibility of combining chlorophyll anomaly analysis with other data types.

Giovanni Jervis'2002 book Individualismo e cooperazione. Psicologia della politica [Individualism and Cooperation: Psychology of Politics] is the outcome of a critical reflection begun by the author at the end of the 1970s in order to explore the manifestations and the problems of cooperation between individuals, and to identify some "universal" psychological factors that could define the role of psychology within politics and constitute an "objective foundation" of any human culture. Although Jervis was, so to speak,favoring Darwin against Marx, it is argued that,from his overall reasoning, several of his arguments actually are in favor of the inevitable "historicity" of individuals, due to the social conditioning they are subjected since birth: too often certain "universalistic" approaches transmit, together with scientific advances (or even without them), well identifiable ideological motives linked to precise and well defined historical and economic interests?

Using NASA's Giovanni System to Simulate Time-Series Stations in the Outflow Region of California's Eel River

Oceanographic time-series stations provide vital data for the monitoring of oceanic processes, particularly those associated with trends over time and interannual variability. There are likely numerous locations where the establishment of a time-series station would be desirable, but for reasons of funding or logistics, such establishment may not be feasible. An alternative to an operational time-series station is monitoring of sites via remote sensing. In this study, the NASA Giovanni data system is employed to simulate the establishment of two time-series stations near the outflow region of California s Eel River, which carries a high sediment load. Previous time-series analysis of this location (Acker et al. 2009) indicated that remotely-sensed chl a exhibits a statistically significant increasing trend during summer (low flow) months, but no apparent trend during winter (high flow) months. Examination of several newly-available ocean data parameters in Giovanni, including 8-day resolution data, demonstrates the differences in ocean parameter trends at the two locations compared to regionally-averaged time-series. The hypothesis that the increased summer chl a values are related to increasing SST is evaluated, and the signature of the Eel River plume is defined with ocean optical parameters.

Mysteries of attraction: Giovanni Pico della Mirandola, astrology and desire.

PubMed

Rutkin, H Darrel

2010-06-01

Although in his later years Giovanni Pico della Mirandola (1463-1494) vehemently rejected astrology, he earlier used it in a variety of ways, but primarily to provide further evidence for positions to which he had arrived by other means. One such early use appears in his commentary on his friend Girolamo Benivieni's love poetry, the Canzone d'amore, of 1486-1487. In the passages discussed here, Pico presents an intensive Platonic natural philosophical analysis based on a deep astrologically informed understanding of human nature as he attempts to explain a perennial question, namely, why one person is attracted to a certain person (or people), and another to others. I will place this discussion of the mysteries of attraction and desire in historical perspective by tracing Pico's changing relationship to astrology during the course of his short but passionate life, and in historiographic perspective by revising Frances Yates's still influential views concerning Pico's contribution to Renaissance thought and his relationship with Marsilio Ficino.

We look at issues, barriers and approaches for Data Fusion of satellite aerosol data as available from the GES DISC GIOVANNI Web Service. Daily Global Maps of AOT from a single satellite sensor alone contain gaps that arise due to various sources (sun glint regions, clouds, orbital swath gaps at low latitudes, bright underlying surfaces etc.). The goal is to develop a fast, accurate and efficient method to improve the spatial coverage of the Daily AOT data to facilitate comparisons with Global Models. Data Fusion may be supplemented by Optimal Interpolation (OI) as needed.

The Medici project consisted in archeological and paleopathological researches on some members of the great dynasty of the Italian Renaissance. The remains of Giovanni de' Medici, so-called "dalle Bande Nere" (Forlì 1498- Mantua 1526) have not been investigated yet. The enigma of the fatal injury and leg amputation of the famous Captain excited curiosity of paleopathologists, medical scientists and Italian Society of Orthopedic and Traumatology which contributed to realize the project of exhumation and study of his skeletal remains. The aim of the study is to report the first anthropological and paleopathological results. The tomb of Giovanni and his wife Maria Salviati was explored and the skeletal remains were investigated. Anthropological and paleopathological examination defined: age at death, physical constitution and activity, skeletal diseases. The bones of the leg were studied macroscopically, under stereoscopic microscope, at X-ray and CT scans to detect type of injury and level of amputation. The skeleton and muscular insertions of Giovanni revealed a young-adult and vigorous man, subjected to stresses of military activity since adolescence. Right tibia was amputated below the proximal half of diaphysis leaving long tibio-fibular stumps with a horizontal cut only at the lateral portion. Thus, the surgeon limited to complete the traumatic hemi-amputation. Amputation in the Sixteenth Century technically consisted in guillotine incisions below the knee using crescent shaped knife and bony saw, usually leaving a quite long tibial stump. Amputations in the Sixteenth Century were contaminated and grossly performed not providing vascular binding nor wound closure. The surgeon performed the procedure in conformity with surgical knowledge of that period.

Giovanni Filippo Ingrassia was born five centuries ago in Regalbuto, a small town in the center of Sicily. After his medical course in Padua, under the guidance of Vesalius and Fallopius, he gained international fame as a physician and was recruited as a Professor of human anatomy in Naples and later in Palermo. He is remembered as "the new Galen" or "the Sicilian Hippocrates." He contributed to the knowledge of human anatomy through the description of single bones rather than the whole skeleton. In particular, he was the first to describe the "stapes," the "lesser wings of the sphenoid" and various other structures in the head (probably the pharyngotympanic tube) as well as in the reproductive system (corpora cavernosa and seminal vesicles). He was also a pioneer in the study of forensic medicine, hygiene, surgical pathology, and teratology. As Protomedicus of Sicily, he developed the scientific culture in this country. During those years, he faced the spread of malaria and plague with competence and authoritativeness. Indeed, he was one of the first physicians to suppose that certain diseases could be transmitted between individuals, therefore, introducing revolutionary measures of prevention. He is remembered for his intellectual authority and honesty. Five-hundred years after his birth, his teaching is still alive. In this article, we survey the life and contribution of this pioneer of early anatomical study. Copyright © 2010 Wiley-Liss, Inc.

"Some curious drawings". Mars through Giovanni Schiaparelli's eyes: between science and fiction.

Canadelli, Elena

2009-01-01

From the second half of the 19th century up to the first part of the 20th century the drawings of Mars by the Italian astronomer Giovanni Schiaparelli became the centre of an international controversy concerning the existence of canals and the hypothetical habitability of the red planet. These images also generated a full impact on the popular culture of the time. This essays follows the scientific representations of Mars by Schiaparelli (drawings of discs and maps) from their birth in the hands of the astronomy community up to their growing old in the hands of scientific popularizers such as Camille Flammarion and science fiction writers such as Herbert George Wells. With its seas and canyons Mars turned into the ideal background for scientific and exotic romanticism, offering a suitable setting for novels and tales. The core question crossed paths with the contemporary early 20th century debate raging on about the evolutionary theory. The study of Mars moved from astronomy to extraterrestrial physiology, biology, meteorology and geography: astronomical images then became imaginary portraits of Martians and artificial Martian landscapes.

The North American Land Data Assimilation System (NLDAS) is a collaboration project between NASA/GSFC, NOAA, Princeton Univ., and the Univ. of Washington. NLDAS has created a surface meteorology dataset using the best-available observations and reanalyses the backbone of this dataset is a gridded precipitation analysis from rain gauges. This dataset is used to drive four separate land-surface models (LSMs) to produce datasets of soil moisture, snow, runoff, and surface fluxes. NLDAS datasets are available hourly and extend from Jan 1979 to near real-time with a typical 4-day lag. The datasets are available at 1/8th-degree over CONUS and portions of Canada and Mexico from 25-53 North. The datasets have been extensively evaluated against observations, and are also used as part of a drought monitor. NLDAS datasets are available from the NASA GES DISC and can be accessed via ftp, GDS, Mirador, and Giovanni. GES DISC news articles were published showing figures from the heat wave of 2011, Hurricane Irene, Tropical Storm Lee, and the low-snow winter of 2011-2012. For this presentation, Giovanni-generated figures using NLDAS data from the derecho across the U.S. Midwest and Mid-Atlantic will be presented. Also, similar figures will be presented from the landfall of Hurricane Isaac and the before-and-after drought conditions of the path of the tropical moisture into the central states of the U.S. Updates on future products and datasets from the NLDAS project will also be introduced.

The Deep Horizon oil spill incident on April 20, 2010 potentially compromised the Gulf Coast's ecosystem and human health through the marine food chain. One of the mitigation strategies to impede oil migration to the Gulf Coast's shorelines was to burn off crude oil, which resulted in the production of polycyclic aromatic hydrocarbon (PAH) emissions such as, benzo[a]anthracene, benzo[a]pyrene, and benzo[b]fluoranthene compounds. Noticeable high deaths of marine animals and a decline in phytoplankton productivity have been linked to PAH- and dispersant-toxicity. Phytoplankton plays a pivotal role in natural food chains, production of O2, and capture of CO2. Grambling State University's Water Quality Management students used the University of New Hampshire's Student Climate Data website and the NASA DICCE data portal in learning activities to understand impacts of spill mitigation on chlorophyll a concentrations. Students used NASA Giovanni data and spectral satellite images to examine phytoplankton productivity around coastal shorelines, including Texas, Louisiana, Mississippi, Alabama, and the Florida pan-handle. Area-averaged time series from Giovanni indicated that June was the peak month for chlorophyll a from 2007 to 2012. Spectral images showed that chlorophyll a concentrations between 2.5-30mg/m3 were widely distributed around the shorelines of Louisiana, Mississippi, and the Florida pan-handle from June 2007 to June 2008. Students then examined chlorophyll a concentrations in April 2010 and May 2010. Data obtained from spectral images by students showed phytoplankton blooms with a 2.5mg/m3 concentration dramatically decreased from that of April 2010. Next students examined phytoplankton productivity from 0.08-30mg/m3 in the month of June for 2010, 2011, and 2012. In June 2010, a pattern of movement in phytoplankton blooms was observed toward southwest Louisiana and Texas shorelines. Comparative data from June 2011 and June 2012 demonstrated a low

Parent, André

Two hundred years ago, Giovanni Aldini published a highly influential book that reported experiments in which the principles of Luigi Galvani (animal electricity) and Alessandro Volta (bimetallic electricity) were used together for the first time. Aldini was born in Bologna in 1762 and graduated in physics at the University of his native town in 1782. As nephew and assistant of Galvani, he actively participated in a series of crucial experiments with frog's muscles that led to the idea that electricity was the long-sought vital force coursing from brain to muscles. Aldini became professor of experimental physics at the University of Bologna in 1798. He traveled extensively throughout Europe, spending much time defending the concept of his discreet uncle against the incessant attacks of Volta, who did not believe in animal electricity. Aldini used Volta's bimetallic pile to apply electric current to dismembered bodies of animals and humans; these spectacular galvanic reanimation experiments made a strong and enduring impression on his contemporaries. Aldini also treated patients with personality disorders and reported complete rehabilitation following transcranial administration of electric current. Aldini's work laid the ground for the development of various forms of electrotherapy that were heavily used later in the 19th century. Even today, deep brain stimulation, a procedure currently employed to relieve patients with motor or behavioral disorders, owes much to Aldini and galvanism. In recognition of his merits, Aldini was made a knight of the Iron Crown and a councillor of state at Milan, where he died in 1834.

There are many existing satellite soil moisture algorithms and their derived data products, but there is no simple way for a user to inter-compare the products or analyze them together with other related data (e.g., precipitation). An environment that facilitates such inter-comparison and analysis would be useful for validation of satellite soil moisture retrievals against in situ data and for determining the relationships between different soil moisture products. The latter relationships are particularly important for applications users, for whom the continuity of soil moisture data, from whatever source, is critical. A recent example was provided by the sudden demise of EOS Aqua AMSR-E and the end of its soil moisture data production, as well as the end of other soil moisture products that had used the AMSR-E brightness temperature data. The purpose of the current effort is to create an environment, as part of the NASA Giovanni family of portals, that facilitates inter-comparisons of soil moisture algorithms and their derived data products.

Giovanni Antonio Scopoli (1723-1788) was one of the most versatile naturalists in eighteenth-century Italy. In 1785, Scopoli conceived the ambitious publication, "Deliciae florae et faunae insubricae". Appearing in installments, this included descriptions and illustrations of plants, animals and minerals found in northern Italy. Unfortunately, Scopoli's sudden death halted publication of the "Deliciae" after its third installment. Recently, a corpus of 98 paintings, in the gouache style, were discovered in the Biblioteca Universitaria of Pavia. These gouaches appear to be the basis for plates planned in future installments of the "Deliciae". Marginal notes in Scopoli's handwriting are included. Because Scopoli's plant and animal specimens have been destroyed or dispersed, these drawings are crucial for reconstructing his scientific opus. Combined with other documents, Scopoli's marginal notes also reveal his exacting standards. He criticized the way his artists had poorly rendered the scientific details of the paintings.

The field of pituitary surgery was born in the first decade of the twentieth century in Europe, and it evolved rapidly with the development of numerous innovative surgical techniques by some of the founding fathers of neurosurgery. This study investigates the pioneering Italian treatise on pituitary surgery, La Patologia Chirurgica dell'Ipofisi (Surgical Pathology of the Hypophysis), published in 1911 by Giovanni Verga (1879-1923), a surgeon from Pavía and one of Golgi's disciples. This little-known monograph compiles the earliest experience on pituitary surgery through the analysis of the first 50 procedures performed between 1903 and 1911. We conducted a biographical survey of Giovanni Verga and the motivations for his work on pituitary surgery. In addition, a systematic analysis of all original reports and historical documents about these pituitary procedures referenced in Verga's treatise was carried out. Verga's treatise provides a summary of the techniques employed and surgical outcomes for the first 50 attempted procedures of pituitary tumor removal. This monograph is the only scientific source that includes a complete account of the series of 10 pituitary tumors operated on by Sir Victor Horsley in the 1900s. Three major types of surgery were employed: (i) palliative procedures of craniectomy (n = 6); (ii) transcranial approaches to the pituitary gland, either subfrontal or subtemporal (n = 13); and (iii) transphenoidal routes to expose the sella turcica, either using an upper transnasal-transethmoidal approach (n = 19) or a lower sublabial/endonasal-transeptal one (n = 12). An operative mortality rate of 36% (n = 17) was observed in these early series. The pathological nature of the tumors operated on was available in 42 cases. There were 28 adenomas and 15 craniopharyngiomas. Sir Victor Horsley (1857-1916) and the Viennese surgeons Anton von Eiselsberg (1860-1939) and Oskar Hirsch (1877-1965) were the leading European figures in the development

The Italian physician Giovanni Battista Morgagni was the founder of the clinico-anatomical method. His masterpiece De sedibus, et causis morborum per anatomen indagatis represented a major breakthrough in the history of medicine. In the murals of Diego Rivera at the National Institute of Cardiology, Morgagni appears at the center of the fresco. With his left index finger points to the chest of a dying patient with a bulging pulsating aortic aneurysm below the left clavicle, and with his right hand, that holds a scalpel, shows the aneurysm found at the autopsy table.

Micro-Raman spectroscopy, combined with gas chromatography and ultra-violet fluorescence photography, was used to study some wall paintings in the S. Giovanni Evangelista Abbey in Parma, Italy. The restoration of some painted chapels enabled a comparison between two painters of the 16th century: Parmigianino (Girolamo Francesco Maria Mazzola, 1503-1540) and Michelangelo Anselmi (1492?-1556?). Micro-Raman spectroscopy determined the palette used by the artists, leading to the identification of different white, yellow, red, brown, green, blue and black pigments. Some pigments are evidence of later restorations. Gas chromatography combined with mass spectroscopy revealed the presence of organic binding media and enabled to distinguish between fresco and secco paintings.

Dolia are large pottery containers used in Roman times for the storage and fermentation of wine. They were produced in specialized pottery workshops ( figlinae) and were typically marked with specific epigraphical stamps, which represent a major tool to unravel their provenance and trade. In this work we present the preliminary results of a study of two dolia defossa, recently found at San Giovanni (Portoferraio, island of Elba, Italy) during 2012-2014 archaeological excavations in a Roman farm (late 2nd cent. BC-1st cent. AD), devoted to wine production and probably constituting the antecedent archaeological phase of the adjacent "Villa delle Grotte". Based on archaeological (epigraphic) evidence, five different production areas have been hypothesized: 1) Elba island, where the dolia have been found; 2) the municipal figlinae in the Pisa territory; 3) the middle catchment of the Tiber river (central Latium) where "urban" figlinae occurred; 4) the figlinae of Minturno (southern Latium), a locality known both for wine production and exportation and for the presence of ancient figlinae; 5) the municipal figlinae in the Volterra territory. Archaeometric analysis of tempering agents intentionally added to the clay for the manufacturing of the dolia, particularly magmatic lithic fragments and clinopyroxene crystals, allowed us to suggest that the watershed of the central Tiber Valley - including different volcanic centres belonging to both Tuscany Magmatic Province (Monti Cimini) and Roman Magmatic Province (Monti Vulsini and Vico volcano) - could have been the most likely sites of production of the dolia found at San Giovanni. Alternatively, the site of Minturno (southern Latium) could be proposed.

The National Cancer Institute of Bari (Istituto di Ricovero e Cura a Carattere Scientifico, IRCCS) has been involved since the conception of the project of the Italian Ministry for Health aimed to validate the applicability of the Organisation of European Cancer Institutes (OECI) accreditation and designation (A&D) model to the Network of Italian Cancer Centers, IRCCS, of Alleanza Contro il Cancro. The self-assessment phase of the Institute started in September 2013 and ended in June 2014. All documents and tools were transferred to the OECI A&D Board in June 2014 and a 2-day peer review visit was conducted in October 2014 by an international qualified audit team. The Institute received its final designation and certification in June 2015. The OECI A&D Board, in its final report, came to the conclusion that Istituto Tumori "Giovanni Paolo II" of Bari has a strong research component with some essential elements of comprehensive cancer care still under development; the lack of a system for using outcome data for the strategic management approach to decision-making and missing a regular internal audit system eventually helping further quality improvement were reported as examples of areas with opportunities for improvement. The OECI A&D process represented a great opportunity for the cancer center to benchmark the quality of its performance according to standard parameters in comparison with other international centers and to further develop a participatory group identity. The common goal of accreditation was real and participatory with long-lasting positive effects. We agree with the OECI comments about the next areas of work in which the Institute could produce future further efforts: the use of its powerful IT system as a means for outcome analysis and empowerment projects for its cancer patients.

Exploring Climatology and Long-Term Variations of Aerosols from NASA Reanalysis MERRA-2 with Giovanni

Dust plays important roles in energy cycle and climate variations. The dust deposition is the major source of iron in the open ocean, which is an essential micronutrient for phytoplankton growth and therefore may influence the ocean uptake of atmospheric CO2. Mineral dust can also act as fertilizer for forests over long time periods. Over 35 years of simulated global aerosol products from NASA atmospheric reanalysis, second Modern-Era Retrospective analysis for Research and Applications (MERRA-2) are available from NASA Goddard Earth Science Data and Information Services Center (GES DISC). The MERRA-2 covers the period 1980-present, continuing as an ongoing climate analysis. Aerosol assimilation is included throughout the period, using MODIS, MISR, AERONET, and AVHRR (in the pre-EOS period). The aerosols are assimilated by using MERRA-2 aerosol model, which interact directly with the radiation parameterization, and radiatively coupled with atmospheric model dynamics in the Goddard Earth Observing System Model, Version 5 (GEOS-5). Dust deposition data along with other major aerosol compositions (e.g. black carbon, sea salt, and sulfate, etc.) are simulated as dry and wet deposition, respectively. The hourly and monthly data are available at spatial resolution of 0.5ox0.625o (latitude x longitude). Quick data exploration of climatology and interannual variations of MERRA-2 aerosol can be done through the online visualization and analysis tool, Giovanni. This presentation, using dust deposition as an example, demonstrates a number of MERRA-2 data services at GES DISC. Global distributions of dust depositions, and their seasonal and inter-annual variations are investigated from MERRA-2 monthly aerosol products.

2015-12-01

Data-enhanced Investigations for Climate Change Education (DICCE) has made it easier and more technologically feasible for secondary and post-secondary instructors and students to study climate change and related Earth system phenomena using data products from the Goddard Interactive Online Visualization and Analysis Infrastructure (GIOVANNI), a powerful portal of Earth observation data that provides access to numerous data products on Earth system phenomena representing the land biosphere, physical land, ocean biosphere, physical ocean, physical atmosphere, atmospheric gases, and energy and radiation system. These data products are derived from remote-sensing instruments on satellites, ground stations, and data assimilation models. Instructors and students can query the GIOVANNI data archive, then save the results as map images, time series plots, vertical profiles of the atmosphere, and data tables. Any part of the world can be selected for analysis. The project has also produced a tool for instructors to author and adapt standards-based lesson plans, student data investigation activities, and presentations around visualizations they make available to their students via DICCE-G. Supports are provided to students and teachers about how to interpret trends in data products of their choice at the regional level and a schema has been developed to help them understand how those data products fit into current scientific thinking about the certainties and uncertainties of climate change. The presentation will (1) describe the features of DICCE, (2) examples of curricula developed to make use of DICCE in classrooms, (3) how these curricula align to Next Generation Science Standards, and (4) how they align to science education research literature about how to make school science more engaging. Recently-analyzed teacher and student outcomes from DICCE use will also be reported.

Testimonies to the L'Aquila earthquake (2009) and to the L'Aquila process

NASA Astrophysics Data System (ADS)

Kalenda, Pavel; Nemec, Vaclav

2014-05-01

Lot of confusions, misinformation, false solidarity, efforts to misuse geoethics and other unethical activities in favour of the top Italian seismologists responsible for a bad and superficial evaluation of the situation 6 days prior to the earthquake - that is a general characteristics for the whole period of 5 years separating us from the horrible morning of April 6, 2009 in L'Aquila with 309 human victims. The first author of this presentation as a seismologist had unusual opportunity to visit the unfortunate city in April 2009. He got all "first-hand" information that a real scientifically based prediction did exist already for some shocks in the area on March 29 and 30, 2009. The author of the prediction Gianpaolo Giuliani was obliged to stop any public information diffused by means of internet. A new prediction was known to him on March 31 - in the day when the "Commission of Great Risks" offered a public assurance that any immediate earthquake can be practically excluded. In reality the members of the commission completely ignored such a prediction declaring it as a false alarm of "somebody" (even without using the name of Giuliani). The observations by Giuliani were of high quality from the scientific point of view. G. Giuliani predicted L'Aquila earthquake in the professional way - for the first time during many years of observations. The anomalies, which preceded L'Aquila earthquake were detected on many places in Europe in the same time. The question is, what locality would be signed as potential focal area, if G. Giuliani would know the other observations in Europe. The deformation (and other) anomalies are observable before almost all of global M8 earthquakes. Earthquakes are preceded by deformation and are predictable. The testimony of the second author is based on many unfortunate personal experiences with representatives of the INGV Rome and their supporters from India and even Australia. In July 2010, prosecutor Fabio Picuti charged the Commission

Ground motion amplification at rock sites: the competing role of topography and fractured rocks in the San Giovanni fault, central Italy

NASA Astrophysics Data System (ADS)

Pischiutta, M.; Cara, F.; Di Giulio, G.; Vassallo, M.; Cultrera, G.

2017-12-01

Amplification at rock sites in areas of high topographic relief has been increasingly observed in the last years, with unexpected level of damage after strong earthquakes. In regions affected by recent tectonic activity, topographic irregularities can include fault damage zones. In such conditions, seismic waves can be locally amplified as a double effect of wave focusing along the topography and /or the presence of fractures/joints or locally weakened rocks. The role of topography vs. geological complexities in controlling the ground motion amplification at rock sites is a newly debated issue in the seismological community. The most crucial questions regard what is the real contribution of the topography shape and fracturing, and how to parameterize such effects for their inclusion in the seismic design codes. In this framework, the EMERSITO INGV task force installed 7 seismic stations across the San Giovanni fault, after the Amatrice mainshock of the 2016 sequence in Central Italy. This active normal fault is located in the area of the Montereale intermountain basin (Abruzzi region, Italy) and bounds the southwestern slope of Mt. Mozzano, a roughly 2D-shaped, up to 1450 m high pronounced topography. Moreover, this fault has been recently studied by several authors who performed detailed geological and geophysical surveys. Our stations recorded more than 100 earthquakes with magnitude ranging from 2.5 to 3.9 as well as a 4.4 M earthquake with hypocenter in Capitignano district, few kilometres far. We have analyzed in detail the recorded signals calculating the traditional spectral ratios at single station (HVSRs) and using the reference site (SSRs) using both ambient noise and earthquakes. In order to obtain a robust estimate of the site amplification effect at each station, we have investigated the influence of backazimuth and epicentral distance. We have also applied the time-domain covariance matrix analysis and the frequency domain polarization analysis. We

Among the known atmospheric constituents, aerosols represent the greatest uncertainty in climate research. Satellite data products are important for a wide variety of applications that can bring far-reaching benefits to the science community and the broader society. These benefits can best be achieved if the satellite data are well utilized and interpreted. Unfortunately, this is not always the case, despite the abundance and relative maturity of numerous satellite-borne sensors routinely measure aerosols. There is often disagreement between similar aerosol parameters retrieved from different sensors, leaving users confused as to which sensors to trust for answering important science questions about the distribution, properties, and impacts of aerosols. Such misunderstanding may be avoided by providing satellite data with accurate pixel-level (Level 2) information, including pixel coverage area delineation and science team recommended quality screening for individual geophysical parameters. NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) have developed multiple MAPSS applications as a part of Giovanni (Geospatial Interactive Online Visualization and Analysis Interface) data visualization and analysis tool - Giovanni-MAPSS and Giovanni-MAPSS_Explorer since 2007. The MAPSS database provides spatio-temporal statistics for multiple spatial spaceborne Level 2 aerosol products (MODIS Terra, MODIS Aqua, MISR, POLDER, OMI, CALIOP, SeaWiFS Deep Blue, and VIIRS) sampled over AERONET ground stations. In this presentation, I will demonstrate the improved features from Giovanni-MAPSS and introduce a new visualization service (Giovanni VizMAP) supporting various visualization and data accessing capabilities from satellite Level 2 data (non-aggregated and un-gridded) at high spatial resolution. Functionality will include selecting data sources (e.g., multiple parameters under the same measurement), defining area-of-interest and temporal extents

NASA Giovanni (Geospatial Interactive Online Visualization ANd aNalysis Infrastructure) (http://giovanni.sci.gsfc.nasa.gov/giovanni/) is a web-based data visualization and analysis system developed by the Goddard Earth Sciences Data and Information Services Center (GES DISC). Current data analysis functions include Lat-Lon map, time series, scatter plot, correlation map, difference, cross-section, vertical profile, and animation etc. The system enables basic statistical analysis and comparisons of multiple variables. This web-based tool facilitates data discovery, exploration and analysis of large amount of global and regional remote sensing and model data sets from a number of NASA data centers. Recently, long term global assimilated atmospheric, land, and ocean data have been integrated into the system that enables quick exploration and analysis of climate data without downloading, and preprocessing the data. Example data include climate reanalysis from NASA Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) which provides data beginning 1980 to present; land data from NASA Global Land Data Assimilation System (GLDAS) which assimilates data from 1948 to 2012; as well as ocean biological data from NASA Ocean Biogeochemical Model (NOBM) which assimilates data from 1998 to 2012. This presentation, using surface air temperature, precipitation, ozone, and aerosol, etc. from MERRA-2, demonstrates climate variation analysis with Giovanni at selected regions.

Rudolph Giuliani and Hillary Rodham Clinton are crisscrossing upstate New York looking for votes in the U.S. Senate race. Also cutting back and forth across upstate New York are hundreds of faults of a kind characterized by very sporadic seismic activity according to Robert Jacobi, professor of geology at the University of Buffalo (UB), who conducted research with fellow UB geology professor John Fountain."We have proof that upstate New York is crisscrossed by faults," Jacobi said. "In the past, the Appalachian Plateau—which stretches from Albany to Buffalo—was considered a pretty boring place structurally without many faults or folds of any significance."

Classification and correction of the radar bright band with polarimetric radar

NASA Astrophysics Data System (ADS)

Hall, Will; Rico-Ramirez, Miguel; Kramer, Stefan

2015-04-01

The annular region of enhanced radar reflectivity, known as the Bright Band (BB), occurs when the radar beam intersects a layer of melting hydrometeors. Radar reflectivity is related to rainfall through a power law equation and so this enhanced region can lead to overestimations of rainfall by a factor of up to 5, so it is important to correct for this. The BB region can be identified by using several techniques including hydrometeor classification and freezing level forecasts from mesoscale meteorological models. Advances in dual-polarisation radar measurements and continued research in the field has led to increased accuracy in the ability to identify the melting snow region. A method proposed by Kitchen et al (1994), a form of which is currently used operationally in the UK, utilises idealised Vertical Profiles of Reflectivity (VPR) to correct for the BB enhancement. A simpler and more computationally efficient method involves the formation of an average VPR from multiple elevations for correction that can still cause a significant decrease in error (Vignal 2000). The purpose of this research is to evaluate a method that relies only on analysis of measurements from an operational C-band polarimetric radar without the need for computationally expensive models. Initial results show that LDR is a strong classifier of melting snow with a high Critical Success Index of 97% when compared to the other variables. An algorithm based on idealised VPRs resulted in the largest decrease in error when BB corrected scans are compared to rain gauges and to lower level scans with a reduction in RMSE of 61% for rain-rate measurements.

Differentiability of energy functionals in spin-density-functional theory

Recently, nonuniqueness of external electrostatic and magnetic fields yielding a given many-electron ground state has been pointed out [K. Capelle and G. Vignale, Phys. Rev. Lett. 86, 5546 (2001); H. Eschrig and W. E. Pickett, Solid State Commun. 118, 123 (2001)], implying the nondifferentiability of the ground-state energy functional of spin-density-functional theory (SDFT), on the basis of which the applicability of widely used DFT methods in SDFT has been put into question and the need for a critical reexamination of those applications has been concluded. Here it is shown, for collinear magnetic fields, that the nonuniqueness of the external potentials in SDFT does not imply the nonexistence of number-conserving functional derivatives as well, with the use of which therefore problems arising from the nondifferentiability are avoided.

Following successful support of the Northern Eurasia Earth Sciences Partner Initiative (NEESPI) project with NASA satellite remote sensing data, from Spring 2009 the NASA GES DISC (Goddard Earth Sciences Data and Information Services Center) has been working on collecting more satellite and model data to support the Monsoon Asia Integrated Regional Study (MAIRS) project. The established data management and service infrastructure developed for NEESPI has been used and improved for MAIRS support.Data search, subsetting, and download functions are available through a single system. A customized Giovanni system has been created for MAIRS.The Web-based on line data analysis and visualization system, Giovanni (Goddard Interactive Online Visualization ANd aNalysis Infrastructure) allows scientists to explore, quickly analyze, and download data easily without learning the original data structure and format. Giovanni MAIRS includes satellite observations from multiple sensors and model output from the NASA Global Land Data Assimilation System (GLDAS), and from the NASA atmospheric reanalysis project, MERRA. Currently, we are working on processing and integrating higher resolution land data in to Giovanni, such as vegetation index, land surface temperature, and active fire at 5km or 1km from the standard MODIS products. For data that are not archived at the GESDISC,a product metadata portal is under development to serve as a gateway for providing product level information and data access links, which include both satellite, model products and ground-based measurements information collected from MAIRS scientists.Due to the large overlap of geographic coverage and many similar scientific interests of NEESPI and MAIRS, these data and tools will serve both projects.

Coulomb drag in electron-hole bilayer: Mass-asymmetry and exchange correlation effects

NASA Astrophysics Data System (ADS)

Arora, Priya; Singh, Gurvinder; Moudgil, R. K.

2018-04-01

Motivated by a recent experiment by Zheng et al. [App. Phys. Lett. 108, 062102 (2016)] on coulomb drag in electron-hole and hole-hole bilayers based on GaAs/AlGaAs semiconductor heterostructure, we investigate theoretically the influence of mass-asymmetry and temperature-dependence of correlations on the drag rate. The correlation effects are dealt with using the Vignale-Singwi effective inter-layer interaction model which includes correlations through local-field corrections to the bare coulomb interactions. However, in this work, we have incorporated only the intra-layer correlations using the temperature-dependent Hubbard approximation. Our results display a reasonably good agreement with the experimental data. However, it is crucial to include both the electron-hole mass-asymmetry and temperature-dependence of correlations. Mass-asymmetry and correlations are found to result in a substantial enhancement of drag resistivity.

Bridging Informatics and Earth Science: a Look at Gregory Leptoukh's Contributions

Lynnes, C.

2012-12-01

With the tragic passing this year of Gregory Leptoukh, the Earth and Space Sciences community lost a tireless participant in--and advocate for--science informatics. Throughout his career at NASA, Dr. Leptoukh established a theme of bridging the gulf between the informatics and science communities. Nowhere is this more evident than his leadership in the development of Giovanni (GES DISC Interactive Online Visualization ANd aNalysis Infrastructure). Giovanni is an online tool that serves to hide the often-complex technical details of data format and structure, making science data easier to explore and use by Earth scientists. To date Giovanni has been acknowledged as a contributor in 500-odd scientific articles. In recent years, Leptoukh concentrated his efforts on multi-sensor data inter-comparison, merging and fusion. This work exposed several challenges at the intersection of data and science. One of these was the ease with which a naive user might generate spurious comparisons, a potential hazard that was the genesis of the Multi-sensor Data Synergy Advisor (MDSA). The MDSA uses semantic ontologies and inference rules to organize knowledge about dataset quality and other salient characteristics in order to advise users on potential caveats for comparing or merging two datasets. Recently, Leptoukh also led the development of AeroStat, an online Giovanni instance to investigate aerosols via statistics from station and satellite comparisons and merged maps of data from more than one instrument. Aerostat offers a neural net based bias adjustment to "harmonize" the data by removing systematic offsets between datasets before merging. These examples exhibit Leptoukh's talent for adopting advanced computer technologies in the service of making science data more accessible to researchers. In this, he set an example that is at once both vital and challenging for the ESSI community to emulate.

The MDSA uses semantic ontologies and inference rules to organize knowledge about dataset quality and other salient characteristics in order to advise users on potential caveats for comparing or merging two datasets. Recently, Leptoukh also led the development of AeroStat, an online Giovanni instance to investigate aerosols via statistics from station and satellite comparisons and merged maps of data from more than one instrument. Aerostat offers a neural net based bias adjustment to harmonize the data by removing systematic offsets between datasets before merging. These examples exhibit Leptoukh's talent for adopting advanced computer technologies in the service of making science data more accessible to researchers. In this, he set an example that is at once both vital and challenging for the ESSI community to emulate.

The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) is the home of processing, archiving, and distribution services for NASA sounders: the present Aqua AIRS mission and the succeeding SNPP CrIS mission. The AIRS mission is entering its 15th year of global observations of the atmospheric state, including temperature and humidity profiles, outgoing longwave radiation, cloud properties, and trace gases. The GES DISC, in collaboration with the AIRS Project, released product from the version 6 algorithm in early 2013. Giovanni, a Web-based application developed by the GES DISC, provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data without having to download the data. Most important variables from version 6 AIRS product are available in Giovanni. We are developing a climatology product using 14-year AIRS retrievals. The study can be a good start for the long term climatology from NASA sounders: the AIRS and the succeeding CrIS. This presentation will show the impacts to the climatology product from different aggregation methods. The climatology can serve climate science and application communities in data visualization and analysis, which will be demonstrated using a variety of functions in version 4 Giovanni. The highlights of these functions include user-defined monthly and seasonal climatology, inter annual seasonal time series, anomaly analysis.

NASA NEESPI (Northern Eurasia Earth Science Partnership Initiative) data portal is a NASA funded project that focuses on collecting satellite remote sensing data, providing tools, information, and services in support of NEESPI scientific objectives (Leptoukh, et al., 2007). The data can be accessed online through anonymous ftp, through an advanced data searching and ordering system Mirador that uses keywords to find data quickly in a Google-like interface, and through the Goddard Interactive Online Visualization ANd aNalysis Infrastructure (Giovanni). The portal provides preprocessed data from different satellite sensors and numerical models to the same spatial and temporal resolution and the same projection so that the data can be used easily to perform inter-comparison or relationship studies. In addition, it provides parameter and spatially subsetted data for regional studies. Studies of regional carbon, hydrology, aerosols in non-boreal Europe and their interactions with global climate are very challenging research topics. The NASA NEESPI data portal makes many satellite data available for such studies, including information on land cover types, fire, vegetation index, aerosols, land surface temperature, soil moisture, precipitation, snow/ice, and other parameters. This paper will introduce the features and products available in the system, focusing on the online data 1 tool, Giovanni NEESPI. An example that explores different data through Giovanni NEESPI in temperate region of non-boreal Europe will be presented.

NASA Giovanni (Goddard Interactive Online Visualization ANd aNalysis Infrastructure) (http:giovanni.sci.gsfc.nasa.govgiovanni) is a web-based data visualization and analysis system developed by the Goddard Earth Sciences Data and Information Services Center (GES DISC). Current data analysis functions include Lat-Lon map, time series, scatter plot, correlation map, difference, cross-section, vertical profile, and animation etc. The system enables basic statistical analysis and comparisons of multiple variables. This web-based tool facilitates data discovery, exploration and analysis of large amount of global and regional remote sensing and model data sets from a number of NASA data centers. Long term global assimilated atmospheric, land, and ocean data have been integrated into the system that enables quick exploration and analysis of climate data without downloading, preprocessing, and learning data. Example data include climate reanalysis data from NASA Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) which provides data beginning in 1980 to present; land data from NASA Global Land Data Assimilation System (GLDAS), which assimilates data from 1948 to 2012; as well as ocean biological data from NASA Ocean Biogeochemical Model (NOBM), which provides data from 1998 to 2012. This presentation, using surface air temperature, precipitation, ozone, and aerosol, etc. from MERRA-2, demonstrates climate variation analysis with Giovanni at selected regions.

In the Hospitals of the Ordine della Provincia Romana San Giovanni di Dio Fatebenefratelli (FBF) (consisting of four hospitals located in three Italian regions) Patient Centeredness has always been considered a central point. In 2015, the Central Hospitals' Health Direction decided to use a check-list for the evaluation of the degree of Patient Centered Care Facilities, drawn up by the National Agency for Regional Health Services (Age.Na.S) during the 2010 Research Project "Experimentation and transfer of organizational empowerment models for evaluating and improving the quality of health services." The aim of the work was to measure the "Patient Centered Care degree" of the FBF structures by means of the Age.Na.S. check-list in order to identify effective and sustainable improvement measures, and to evaluate the applicability and the critical points of the questionnaire. The check-list was divided into four areas: care systems oriented at citizen's respect and centrality; physical accessibility, liveability and comfort of the places of care; access to information, simplification and transparency; care of the relationship with the patient and the citizen. The four areas were divided into 12 sub-areas, 29 criteria and 144 items with sub-items (248 questions), defined as quantitative or qualitative variables allowing for an evaluation of observed reality. Some items from different areas have been grouped into Focus and Operational Units (UU.OO./Facilities). The results of the Age.Na.S. study were used to compare the results obtained in the Roman Province FBF structures with the national ones. The Medical Directors and the responsible of FBF Quality Systems completed the cheek-list. A working group within the Central Hospitals' Health Direction analysed the data and processed the results, using the same scores provided by Age.Na.S.. The analysis of the results was divided into three levels. Focus and UU.OO./Facilities scores were calculated based on Age.Na.S. The

The Goddard Space Flight Center Earth Sciences Data and Information Services Center (GES DISC) Distributed Active Archive Center (DAAC) is developing an Agricultural Information System (AIS), evolved from an existing TRMM Online Visualization and Analysis System (TOVAS), which will operationally provide precipitation and other satellite data products and services. AIS outputs will be integrated into existing operational decision support systems for global crop monitoring, such as that of the U.N. World Food Program. The ability to use the raw data stored in the GES DAAC archives is highly dependent on having a detailed understanding of the data's internal structure and physical implementation. To gain this understanding is a time-consuming process and not a productive investment of the user's time. This is an especially difficult challenge when users need to deal with multi-sensor data that usually are of different structures and resolutions. The AIS has taken a major step towards meeting this challenge by incorporating an underlying infrastructure, called the GES-DISC Interactive Online Visualization and Analysis Infrastructure or "Giovanni," that integrates various components to support web interfaces that allow users to perform interactive analysis on-line without downloading any data. Several instances of the Giovanni-based interface have been or are being created to serve users of TRMM precipitation, MODIS aerosol, and SeaWiFS ocean color data, as well as agricultural applications users. Giovanni-based interfaces are simple to use but powerful. The user selects geophysical parameters, area of interest, and time period; and the system generates an output on screen in a matter of seconds. The currently available output options are (1) area plot - averaged or accumulated over any available data period for any rectangular area; (2) time plot - time series averaged over any rectangular area; (3) Hovmoller plots - longitude-time and latitude-time plots; (4) ASCII

The Precipitation Data and Information Services Center (PDISC) (http://disc.gsfc.nasa.gov/precipitation or google: NASA PDISC), located at the NASA Goddard Space Flight Center (GSFC) Earth Sciences (GES) Data and Information Services Center (DISC), is home of the Tropical Rainfall Measuring Mission (TRMM) data archive. For over 15 years, the GES DISC has served not only TRMM, but also other space-based, airborne-based, field campaign and ground-based precipitation data products to the precipitation community and other disciplinary communities as well. The TRMM Multi-Satellite Precipitation Analysis (TMPA) products are the most popular products in the TRMM product family in terms of data download and access through Mirador, the GES-DISC Interactive Online Visualization ANd aNalysis Infrastructure (Giovanni) and other services. The next generation of TMPA, the Integrated Multi-satellitE Retrievals for GPM (IMERG) to be released in 2014 after the launch of GPM, will be significantly improved in terms of spatial and temporal resolutions. To better serve the user community, we are preparing data services and samples are listed below. To enable scientific exploration of Earth science data products without going through complicated and often time consuming processes, such as data downloading, data processing, etc., the GES DISC has developed Giovanni in consultation with members of the user community, requesting quick search, subset, analysis and display capabilities for their specific data of interest. For example, the TRMM Online Visualization and Analysis System (TOVAS, http://disc2.nascom.nasa.gov/Giovanni/tovas/) has proven extremely popular, especially as additional datasets have been added upon request. Giovanni will continue to evolve to accommodate GPM data and the multi-sensor data inter-comparisons that will be sure to follow. Additional PDISC tool and service capabilities being adapted for GPM data include: An on-line PDISC Portal (includes user guide, etc

Proto-Examples of Data Access and Visualization Components of a Potential Cloud-Based GEOSS-AI System

NASA Technical Reports Server (NTRS)

Teng, William; Lynnes, Christopher

2014-01-01

Once a research or application problem has been identified, one logical next step is to search for available relevant data products. Thus, an early component of a potential GEOSS-AI system, in the continuum between observations and end point research, applications, and decision making, would be one that enables transparent data discovery and access by users. Such a component might be effected via the systems data agents. Presumably, some kind of data cataloging has already been implemented, e.g., in the GEOSS Common Infrastructure (GCI). Both the agents and cataloging could also leverage existing resources external to the system. The system would have some means to accept and integrate user-contributed agents. The need or desirability for some data format internal to the system should be evaluated. Another early component would be one that facilitates browsing visualization of the data, as well as some basic analyses.Three ongoing projects at the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) provide possible proto-examples of potential data access and visualization components of a cloud-based GEOSS-AI system. 1. Reorganizing data archived as time-step arrays to point-time series (data rods), as well as leveraging the NASA Simple Subset Wizard (SSW), to significantly increase the number of data products available, at multiple NASA data centers, for production as on-the-fly (virtual) data rods. SSWs data discovery is based on OpenSearch. Both pre-generated and virtual data rods are accessible via Web services. 2. Developing Web Feature Services to publish the metadata, and expose the locations, of pre-generated and virtual data rods in the GEOSS Portal and enable direct access of the data via Web services. SSW is also leveraged to increase the availability of both NASA and non-NASA data.3.Federating NASA Giovanni (Geospatial Interactive Online Visualization and Analysis Interface), for multi-sensor data exploration, that would allow each

Density-functional theory for internal magnetic fields

NASA Astrophysics Data System (ADS)

Tellgren, Erik I.

2018-01-01

A density-functional theory is developed based on the Maxwell-Schrödinger equation with an internal magnetic field in addition to the external electromagnetic potentials. The basic variables of this theory are the electron density and the total magnetic field, which can equivalently be represented as a physical current density. Hence, the theory can be regarded as a physical current density-functional theory and an alternative to the paramagnetic current density-functional theory due to Vignale and Rasolt. The energy functional has strong enough convexity properties to allow a formulation that generalizes Lieb's convex analysis formulation of standard density-functional theory. Several variational principles as well as a Hohenberg-Kohn-like mapping between potentials and ground-state densities follow from the underlying convex structure. Moreover, the energy functional can be regarded as the result of a standard approximation technique (Moreau-Yosida regularization) applied to the conventional Schrödinger ground-state energy, which imposes limits on the maximum curvature of the energy (with respect to the magnetic field) and enables construction of a (Fréchet) differentiable universal density functional.

Using NASA satellite remote sensing data from multiple sources for hydrologic applications can be a daunting task and requires a detailed understanding of the data's internal structure and physical implementation. Gaining this understanding and applying it to data reduction is a time-consuming task that must be undertaken before the core investigation can begin. In order to facilitate such investigations, the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) has developed the GES-DISC Interactive Online Visualization ANd aNalysis Infrastructure or "Giovanni," which supports a family of Web interfaces (instances) that allow users to perform interactive visualization and analysis online without downloading any data. Two such Giovanni instances are particularly relevant to hydrologic applications: the Tropical Rainfall Measuring Mission (TRMM) Online Visualization and Analysis System (TOVAS) and the Agricultural Online Visualization and Analysis System (AOVAS), both highly popular and widely used for a variety of applications, including those related to several NASA Applications of National Priority, such as Agricultural Efficiency, Disaster Management, Ecological Forecasting, Homeland Security, and Public Health. Dynamic, context- sensitive Web services provided by TOVAS and AOVAS enable users to seamlessly access NASA data from within, and deeply integrate the data into, their local client environments. One example is between TOVAS and Florida International University's TerraFly, a Web-enabled system that serves a broad segment of the research and applications community, by facilitating access to various textual, remotely sensed, and vector data. Another example is between AOVAS and the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS)'s Crop Explorer, the primary decision support tool used by FAS to monitor the production, supply, and demand of agricultural commodities worldwide. AOVAS is also part of GES DISC

As against the background of an unconditioned reception of Darwinian theory and its developments, mainly in the field of ethology, a reflection deploys itself on complex theoretical themes, such as identity, consciousness and motivation. This leads Jervis to deal not only and not as much with psychoanalysis, as with a broader theoretical framework, labelled as "dynamic psychology". Contributions from different fields of contemporary psychological knowledge, particularly from cognitive sciences, personality and social psychology and developmental observations converge into this new framework. A proposal is made that is characterized by a peculiar critical sensitivity and is open to future developments. It is in this new light that Jervis was able to carry out a retrospective recognition of the century of Psychoanalysis.

Vegetation growth depends on local climate. Significant anthropogenic land cover and land use change activities over Asia have changed vegetation distribution as well. On the other hand, vegetation is one of the important land surface variables that influence the Asian Monsoon variability through controlling atmospheric energy and water vapor conditions. In this presentation, the mean and variations of vegetation index of last decade at regional scale resolution (5km and higher) from MODIS have been analyzed. Results indicate that the vegetation index has been reduced significantly during last decade over fast urbanization areas in east China, such as Yangtze River Delta, where local surface temperatures were increased significantly in term of urban heat Island. The relationship between vegetation Index and climate (surface temperature, precipitation) over a grassland in northern Asia and over a woody savannas in southeast Asia are studied. In supporting Monsoon Asian Integrated Regional Study (MAIRS) program, the data in this study have been integrated into Giovanni, the online visualization and analysis system at NASA GES DISC. Most images in this presentation are generated from Giovanni system.

Motivation: Recall the arguably most renowned anecdote in the history of science: the young Isaac Newton was hit on his head by a falling apple (the data!) when he sat in his garden, which inspired Newton's brilliant insight and his eventually understanding and demonstrating of gravitational force (the science!). This well-known "coupling" of "data" and "science" can be considered as the trigger for this study (as well as its title). The NASA Goddard Earth Sciences Data and Information Service Center (GES DISC) has provided massive amounts of Earth science data, information, and services to diverse research communities and the general public for decades. How much those data products from different missions or projects have been used by diverse user communities, as well as how they have been used by our various user categories (such as research scientists, applications scientists, general public, and students) for different science research or/and applications are the primary focus of this study. We have performed an integrated analysis on "data usage" vs. "science research/application" by investigating three different, yet related, groups of records, i.e., user Help Tickets (the questions and feedback from the users), user publications (info acquired especially via users' acknowledgments of using Giovanni, our powerful in-house visualization tool, in their papers), and user metrics (the collected information of data and service usage by the users) in recent years (2013-2017). For example, precipitation, hydrology, and atmospheric chemistry have been found as frequently applied science variables or/and science areas that have been exploited or/and explored by the users based on the user tickets we have analyzed so far. With regard to Giovanni, a significant minority of the users are applications users (air quality, water quality, agriculture, natural disasters, etc.) in contrast to the majority of basic research users. More users employ Giovanni as an adjunct data

Exploring and Visualizing A-Train Instrument Data

The succession of US and international satellites that follow each other in close succession, known as the A-Train, affords an opportunity to atmospheric researchers that no single platform could provide: Increasing the number of observations at any given geographic location.. . a more complete "virtual science platform". However, vertically and horizontally, co-registering and regridding datasets from independently developed missions, Aqua, Calipso, Cloudsat, Parasol, and Aura, so that they can be inter-compared can be daunting to some, and may be repeated by many. Scientists will individually spend much of their time and resources acquiring A-Train datasets of interest residing at various locations, developing algorithms to match up and graph datasets along the A-Train track, and search through large amounts of data for areas and/or phenomena of interest. The aggregate amount of effort that can be expended on repeating pre-science tasks could climb into the tens of millions of dollars. The goal of the A-Train Data Depot (ATDD) is to enable free movement of remotely located A-Train data so that they are combined to create a consolidated vertical view of the Earth's Atmosphere along the A-Train tracks. The innovative approach of analyzing and visualizing atmospheric profiles along the platforms track (i.e., time) is accomplished by through the ATDDs Giovanni data analysis and visualization tool. Giovanni brings together data from Aqua (MODIS, AIRS, AMSR-E), Cloudsat (cloud profiling radar) and Calipso (CALIOP, IIR), as well as the Aura (OMI, MLS, HIRDLS, TES) to create a consolidated vertical view of the Earth's Atmosphere along the A-Train tracks. This easy to learn and use exploration tool will allow users to create vertical profiles of any desired A-Train dataset, for any given time of choice. This presentation shows the power of Giovanni by describing and illustrating how this tool facilitates and aids A-Train science and research. A web based display system

Three applications were successfully migrated to Nebula, including S4PM, AIRS L1/L2 algorithms, and Giovanni MAPSS. Nebula has some advantages compared with local machines (e.g. performance, cost, scalability, bundling, etc.). Nebula still faces some challenges (e.g. stability, object storage, networking, etc.). Migrating applications to Nebula is feasible but time consuming. Lessons learned from our Nebula experience will benefit future Cloud Computing efforts at GES DISC.

Integration of aerial and satellite remote sensing for archaeological investigations: a case study of the Etruscan site of San Giovenale

NASA Astrophysics Data System (ADS)

Lasaponara, R.; Masini, N.; Holmgren, R.; Backe Forsberg, Y.

2012-08-01

The objective of this research is to detect and extract traces of past human activities on the Etruscan site of San Giovenale (Blera) in Northern Lazio, Italy. Investigations have been conducted by integrating high-resolution satellite data with digital models derived from LiDAR survey and multisensory aerial prospection (traditional, thermal and near infrared pictures). The use of different sensor technologies is requested to cope with (i) different types of surface covers, i.e. vegetated and non-vegetated areas (trees, bushes, agricultural uses, etc), (ii) variety of archaeological marks (micro-relief, crop marks, etc) and (iii) different types of expected spatial/spectral feature patterns linked to past human activities (urban necropoleis, palaeorivers, etc). Field surveys enabled us to confirm remotely sensed features which were detected in both densely and sparsely vegetated areas, thus revealing a large variety of cultural transformations, ritual and infrastructural remains such as roads, tombs and water installations. Our findings clearly point out a connection between the Vignale plateau and the main acropolis (San Giovenale) as well as with the surrounding burial grounds. Our results suggest that the synergic use of multisensory/multisource data sets, including ancillary information, provides a comprehensive overview of new findings. This facilitates the interpretation of various results obtained from different sensors when studied in a larger prospective.

Analyzing a 35-Year Hourly Data Record: Why So Difficult?

NASA Technical Reports Server (NTRS)

Lynnes, Chris

2014-01-01

At the Goddard Distributed Active Archive Center, we have recently added a 35-Year record of output data from the North American Land Assimilation System (NLDAS) to the Giovanni web-based analysis and visualization tool. Giovanni (Geospatial Interactive Online Visualization ANd aNalysis Infrastructure) offers a variety of data summarization and visualization to users that operate at the data center, obviating the need for users to download and read the data themselves for exploratory data analysis. However, the NLDAS data has proven surprisingly resistant to application of the summarization algorithms. Algorithms that were perfectly happy analyzing 15 years of daily satellite data encountered limitations both at the algorithm and system level for 35 years of hourly data. Failures arose, sometimes unexpectedly, from command line overflows, memory overflows, internal buffer overflows, and time-outs, among others. These serve as an early warning sign for the problems likely to be encountered by the general user community as they try to scale up to Big Data analytics. Indeed, it is likely that more users will seek to perform remote web-based analysis precisely to avoid the issues, or the need to reprogram around them. We will discuss approaches to mitigating the limitations and the implications for data systems serving the user communities that try to scale up their current techniques to analyze Big Data.

A Morgagni hernia was first described in 1761 by Giovanni Morgagni. In adults, it is accompanied by gastrointestinal- or respiratory-type symptoms. Herein, we report an 84-year-old woman presented to our hospital with nausea and vomiting. After hospitalization, an X-ray revealed a right diaphragmatic hernia. Based on the results of abdominal computed tomography, duodenoscopy, and upper gastrointestinography (gastrografin), we concluded that her symptoms were caused by Morgagni hernia. Our patient underwent laparoscopic surgery, and shortly thereafter, her symptoms resolved.

Scientific method, history, Darwinism and laicism: a Giovanni Jervis's intellectual biography.

PubMed

Corbellini, Gilberto; Sirgiovanni, Elisabetta

2012-01-01

Some authors marked a change of perspective from the early to the late Jervis's thought, in terms of a supposed turn towards conservatism. That laid him open to criticism from some Leftist Italian intellectuals. The aim of this paper is to show that conservatism never was a Jervis's thought feature. Mainly, subjects and methods leading the development of his philosophical views suggest a continuity between earlier writings and later ones. All over his thought, in fact, the idea of preeminence of scientific method and historical contextualization convinced him about naturalistic approaches to human behavior, which came to support his Darwinism and laicism in approaching socio-psychological and socio-political issues.

Giovanni Jervis left us. There is only one way to cope with the irremediable separation: to give voice to what he said and wrote, by keeping open among us questions he asked, because they are also ours. In this dialogue with Giacomo Marramao let me begin with certain passages of the essay Psychoanalysis as a Critical Exercise that Jervis published in 1989. In the second part of the intervention I will try to explain why, in my opinion, hermeneutics cannot be equated with "relativism".

Sorbellini, Elisabetta; Pinto, Daniela; Marzani, Barbara; Rinaldi, Fabio

2018-06-01

Treatment with finasteride 1 mg/day represents the therapy of choice for androgenetic alopecia (AGA). We investigated how Italian dermatologists approach use of finasteride for treatment of AGA and common side effects reported by patients. A tablet-based survey was conducted from February 2017 to January 2018 in Italy to investigating use of 1 mg/day finasteride in the treatment of AGA. Approximately 1153 Italian dermatologists were surveyed about prescription frequency, therapy duration, treatment practices, and side effects eventually reported. Dermatologists considered treatment with 1 mg/day finasteride to be the most efficacious treatment for AGA, as reflecting by its long-term (5 years) prescription. Data on sexual side effects from our survey are in line with previous scientific evidence, especially regarding loss of libido, erectile dysfunction, and problems with ejaculation, but also in the psychological sphere and regarding physical impairments such as myalgia and loss of muscle tone. This is the first preliminary observational study on how Italian dermatologists approach use of finasteride to treat AGA. Although side effects have been reported, especially in the sexual sphere, lack of alternative treatments with the same efficacy leads dermatologists to prescribe 1 mg/day finasteride with a tendency to prolong therapy in the long term.

Gazzaniga, Valentina; Marinozzi, Silvia

2006-01-01

Giovanni Maria Lancisi (1654-1720) shows a particular interest in urological and nephrological diseases, especially evident in a course of lectures held at Studium Urbis in 1696-97, which reflected his vast knowledge and familiarity with various important texts devoted to urology and nephrology. This interest is further documented in commentaries on articles on nephrological diseases in his Repertorium medicum (a sort of medical dictionary written between 1672 and his death). Lancisi's quoting medical authorities clarifies the clinical answers he gave in some of his unpublished Consulti concerning nephrological pathologies.

Intrinsic domain wall flexing from current-induced spin torque

NASA Astrophysics Data System (ADS)

Golovatski, Elizabeth; Flatté, Michael

2012-02-01

Spin torque generated by coherent carrier transport in domain walls [1] is a major component in the development of spintronic devices [2]. We model spin torque in N'eel walls [3] using a piecewise linear transfer-matrix method [4] to calculate spin torque on interior wall segments. For a π wall with a total positive torque (current left-to-right), we find the largest positive and negative spin torques left of the central region, 4-5 orders of magnitude larger than the center. The wall's rightward push comes from the back of the wall; all other significant regions pull to the left. Adding a second wall (both walls with positive total torque) changes the first wall little, but produces spin torques in the second wall with large canceling torques on the left, and the push rightward from a smaller torque on the right. The gradient of torque across the wall generates an intrinsic domain wall flexing (distinct from extrinsic wall flexing from pinning centers [5]). Work supported by an ARO MURI.[4pt] [1] M.

The therapeutic approaches used against scrofula in the 19th Century in Ferrara are discussed. In the manuscripts and treatises of the time treasured in the town's libraries, hygienic and dietetic rules and treatment of this illness were described. In particular, baths and mineral water spas (sulphurous, ferruginous and other mineral waters, such as a bromo-iodine-salt water) and the sea-bathing establishment were recommended. The remedies reported in Campana's Pharmacopoeia ferrarese and the efficacious treatments employed in St Anna Hospital are discussed. The Committee and its President, Marquis Giovanni Manfredini, decided to cure the scrofulous in bathing establishments.

Troubles with self-consciousness. Jervis on introspection and defense mechanisms.

PubMed

Marraffa, Massimo

2012-01-01

Building on Sigmund Freud, Ernesto de Martino and cognitive sciences, Giovanni Jervis has outlined a view of introspective consciousness as primarily an activity of narrative re-appropriation of the outputs of the unconscious cognitive processing, emphasizing that such an activity is ruled by the primary need to construct an identity that is valid as much as possible. Thus Jervis has originally pursued an integration between the anti-introspectionist tradition in cognitive sciences and the psychodynamic investigation on defense mechanisms. This paper outlines Jervis' attempt to integrate these two traditions, and shows that it fits very well with recent developments of the theory-theory approach to self-knowledge.

We have investigated with terahertz time-domain imaging (THz-TDI) the well-known Lamentation over the dead Christ panel painting (San Marco Museum, Florence) painted by Fra Giovanni Angelico within 1436 and 1441. The investigation provided a better understanding of the construction and gilding technique used by the eminent artist, as well as the plastering technique used during the nineteenth-century restoration intervention. The evidence obtained from THz-TDI scans was correlated with the available documentation on the preservation history of the art piece. Erosion and damages documented for the wooden support, especially in the lower margin, found confirmation in the THz-TD images.

Developing GIOVANNI-based Online Prototypes to Intercompare TRMM-Related Global Gridded-Precipitation Products

2014-01-01

New online prototypes have been developed to extend and enhance the previous effort by facilitating investigation of product characteristics and intercomparison of precipitation products in different algorithms as well as in different versions at different spatial scales ranging from local to global without downloading data and software. Several popular Tropical Rainfall Measuring Mission (TRMM) products and the TRMM Composite Climatology are included. In addition, users can download customized data in several popular formats for further analysis. Examples show product quality problems and differences in several monthly precipitation products. It is seen that differences in daily and monthly precipitation products are distributed unevenly in space and it is necessary to have tools such as those presented here for customized and detailed investigations. A simple time series and two area maps allow the discovery of abnormal values of 3A25 in one of the months. An example shows a V-shaped valley issue in the Version 6 3B43 time series and another example shows a sudden drop in 3A25 monthly rain rate, all of which provide important information when the products are used for long-term trend studies. Future plans include adding more products and statistical functionality in the prototypes.

Accessing and Utilizing Remote Sensing Data for Vectorborne Infectious Diseases Surveillance and Modeling

NASA Technical Reports Server (NTRS)

Kiang, Richard; Adimi, Farida; Kempler, Steven

2008-01-01

Background: The transmission of vectorborne infectious diseases is often influenced by environmental, meteorological and climatic parameters, because the vector life cycle depends on these factors. For example, the geophysical parameters relevant to malaria transmission include precipitation, surface temperature, humidity, elevation, and vegetation type. Because these parameters are routinely measured by satellites, remote sensing is an important technological tool for predicting, preventing, and containing a number of vectorborne infectious diseases, such as malaria, dengue, West Nile virus, etc. Methods: A variety of NASA remote sensing data can be used for modeling vectorborne infectious disease transmission. We will discuss both the well known and less known remote sensing data, including Landsat, AVHRR (Advanced Very High Resolution Radiometer), MODIS (Moderate Resolution Imaging Spectroradiometer), TRMM (Tropical Rainfall Measuring Mission), ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer), EO-1 (Earth Observing One) ALI (Advanced Land Imager), and SIESIP (Seasonal to Interannual Earth Science Information Partner) dataset. Giovanni is a Web-based application developed by the NASA Goddard Earth Sciences Data and Information Services Center. It provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data. After remote sensing data is obtained, a variety of techniques, including generalized linear models and artificial intelligence oriented methods, t 3 can be used to model the dependency of disease transmission on these parameters. Results: The processes of accessing, visualizing and utilizing precipitation data using Giovanni, and acquiring other data at additional websites are illustrated. Malaria incidence time series for some parts of Thailand and Indonesia are used to demonstrate that malaria incidences are reasonably well modeled with generalized linear models and artificial

"Citizen science" generally refers to observatoinal research and data collection conducted by non-professionals, commonly as volunteers. In the environmental science field, citizen scientists may be involved with local nad regional issues such as bird and wildlife populations, weather, urban sprawl, natural hazards, wetlands, lakes and rivers, estuaries, and a spectrum of public health concerns. Some citizen scientists may be primarily motivated by the intellectual challenge of scientific observations. Citizen scientists may now examine and utilize remote-sensing data related to their particular topics of interest with the easy-to-use NASA Web-based tools Giovanni and NEO, which allow exploration and investigation of a wide variety of Earth remote sensing data sets. The CARSON (Citizens and Remote Sensing Observational Network) Guide will be an online resource consisting of chapters each demonstrating how to utilize Giovanni and NEO to access and analyze specific remote-sensing data. Integrated in each chapter will be descriptions of methods that citizen scientists can employ to collect, monitor, analyze, and share data related to the chapter topic which pertain to environmental and ecological conditions in their local region. A workshop held in August 2008 initiated the development of prototype chapters on water quality, air quality, and precipitation. These will be the initial chapters in the first release of the CARSON Guide, which will be used in a pilot project at the Maryland Science Center in spring 2009. The goal of the CARSON Guide is to augment and enhance citizen scientist environmental research with NASA satellite data by creating a participatory network consisting of motivated individuals, environmental groups and organizations, and science-focused institutions such as museuma and nature centers. Members of the network could potentially interact with government programs, academic research projects, and not-for-profit organizations focused on

The Giornale de' letterati published in Rome from 1668 to 1681 was the first Italian scientific journal. It was meant to be the Italian version of the French Journal des Sçavans or the English Philosophical Transactions. Unlike these two, it was not backed by a formal or informal scientific institution, even if one of its editors, Giovanni Giustino Ciampini, was the founder of the Accademia Fisico-Matematica, the leading scientific academy in Rome in the second half of the XVIIth century. The paper, a preliminary step in a study on the diffusion and communication of European medical culture in Rome in this period, indexes and broadly examines the articles pertaining to medicine published in the journal.

Geogenic Enrichment of PTEs and the " Serpentine Syndrome"(H. Jenny, 1980). A proxy for soil remediation

NASA Astrophysics Data System (ADS)

Bini, Claudio; Maleci, Laura

2014-05-01

Serpentine soils have relatively high concentrations of PTEs (e.g., Co, Cr, Cu, Fe, Ni) but generally low amounts of major nutrients. They often bear a distinctive vegetation, and a frequently-used approach to understanding serpentine ecology and environmental hazard has been the chemical analysis of soils and plants. Long-term studies on aspects of serpentine soils and their vegetation provide results on total concentrations, or on plant-available fractions, of soil elements which counteract ecological conditions. For example, there is evidence of Ni toxicity at Ni-concentration >0.3 mg/L in the soil solution (Johnston and Proctor, 1981). The serpentine vegetation differs from the conterminous non-serpentine areas, being often endemic, and showing macroscopic physionomical characters such as dwarfism, prostrate outcome, glaucescence and glabrescence, leaves stenosis, root shortening (what Jenny, 1980, called "the serpentine syndrome"). Similarly, at microscopic level cytomorphological characteristics of the roots and variations in biochemical parameters such as LPO and phenols have been recorded in serpentine native vegetation (Giuliani et al., 2008). Light microscopy observations showed depressed mitotic activity in the meristematic zone, and consequent reduced root growth (Gabbrielli et al., 1990) The metal content of plants growing on serpentine soils at sites with different microclimatic conditions has been examined by several authors (e.g. Bini et al., 1993; Dinelli and Lombini, 1996) . A preferential Ni distribution in epidermis and sclerenchima has been observed in the stem of Alyssum bertoloni, a well known Ni-accumulator plant (Vergnano Gambi, 1975). The different tolerance mechanisms responsible for plant adaption to high concentrations of PTEs in serpentine soils can be related to the capacity of plants either to limit metal uptake and translocation or to accumulate metals in non toxic forms. The majority of serpentine species (e.g. Silene italica) tend

Time-Dependent Density-Functional Theory (TDDFT) is a well-established theoretical approach to describe and understand irradiation processes in clusters and molecules.

Time-Dependent Density-Functional Theory (TDDFT) is a well-established theoretical approach to describe and understand irradiation processes in clusters and molecules. However, within the so-called adiabatic local density approximation (ALDA) to the exchange-correlation (xc) potential, TDDFT can show insufficiencies, particularly in violently dynamical processes. This is because within ALDA the xc potential is instantaneous and is a local functional of the density, which means that this approximation neglects memory effects and long-range effects.

Cloud Computing technology has been used to offer high-performance and low-cost computing and storage resources for both scientific problems and business services. Several cloud computing services have been implemented in the commercial arena, e.g. Amazon's EC2 & S3, Microsoft's Azure, and Google App Engine. There are also some research and application programs being launched in academia and governments to utilize Cloud Computing. NASA launched the Nebula Cloud Computing platform in 2008, which is an Infrastructure as a Service (IaaS) to deliver on-demand distributed virtual computers. Nebula users can receive required computing resources as a fully outsourced service. NASA Goddard Earth Science Data and Information Service Center (GES DISC) migrated several GES DISC's applications to the Nebula as a proof of concept, including: a) The Simple, Scalable, Script-based Science Processor for Measurements (S4PM) for processing scientific data; b) the Atmospheric Infrared Sounder (AIRS) data process workflow for processing AIRS raw data; and c) the GES-DISC Interactive Online Visualization ANd aNalysis Infrastructure (GIOVANNI) for online access to, analysis, and visualization of Earth science data. This work aims to evaluate the practicability and adaptability of the Nebula. The initial work focused on the AIRS data process workflow to evaluate the Nebula. The AIRS data process workflow consists of a series of algorithms being used to process raw AIRS level 0 data and output AIRS level 2 geophysical retrievals. Migrating the entire workflow to the Nebula platform is challenging, but practicable. After installing several supporting libraries and the processing code itself, the workflow is able to process AIRS data in a similar fashion to its current (non-cloud) configuration. We compared the performance of processing 2 days of AIRS level 0 data through level 2 using a Nebula virtual computer and a local Linux computer. The result shows that Nebula has significantly

During the Modern Age, in the Marche, in the Pontifical State, it was possible to study medicine and to obtain a degree in medicine in Macerata, Fermo, Urbino, Camerino and Fano. In these cities, from the end of the XVII century to the beginning of the XIX century, public libraries were founded also to support academic teaching. Private collections of medical books, generally formed in Rome, arrived in the Marche to increase the newborn public libraries. In 1720 Pope Clemens XI founded a public library in the monastery of Saint Francis in Urbino. In this library the medical books were bequeathed by the famous Roman physician Giovanni Maria Lancisi. The present article provides the first results of a research, which aims at identifying Lancisi's medical books.

Sir Victor Horsley: pioneer craniopharyngioma surgeon.

PubMed

Pascual, José M; Prieto, Ruth; Mazzarello, Paolo

2015-07-01

Sir Victor Horsley (1857-1916) is considered to be the pioneer of pituitary surgery. He is known to have performed the first surgical operation on the pituitary gland in 1889, and in 1906 he stated that he had operated on 10 patients with pituitary tumors. He did not publish the details of these procedures nor did he provide evidence of the pathology of the pituitary lesions operated on. Four of the patients underwent surgery at the National Hospital for Neurology and Neurosurgery (Queen Square, London), and the records of those cases were recently retrieved and analyzed by members of the hospital staff. The remaining cases corresponded to private operations whose records were presumably kept in Horsley's personal notebooks, most of which have been lost. In this paper, the authors have investigated the only scientific monograph providing a complete account of the pituitary surgeries that Horsley performed in his private practice, La Patologia Chirurgica dell'Ipofisi (Surgical Pathology of the Hypophysis), written in 1911 by Giovanni Verga, Italian assistant professor of anatomy at the University of Pavia. They have traced the life and work of this little-known physician who contributed to the preservation of Horsley's legacy in pituitary surgery. Within Verga's pituitary treatise, a full transcription of Horsley's notes is provided for 10 pituitary cases, including the patients' clinical symptoms, surgical techniques employed, intraoperative findings, and the outcome of surgery. The descriptions of the topographical and macroscopic features of two of the lesions correspond unmistakably to the features of craniopharyngiomas, one of the squamous-papillary type and one of the adamantinomatous type. The former lesion was found on necropsy after the patient's sudden death following a temporal osteoplastic craniectomy. Surgical removal of the lesion in the latter case, with the assumed nature of an adamantinomatous craniopharyngioma, was successful. According to the

Twenty years of biophysics of photosynthesis in Padova, Italy (1984-2005): a tale of two brothers.

This paper tells the history of two brothers, almost a generation apart in age, who met again, after having followed different academic paths, to introduce biophysical research in photosynthesis at the University of Padova. The development of two research groups, one in the Chemistry Department, the other in the Biology Department led to a comprehensive interdisciplinary group across academic barriers. The group of Giovanni Giacometti developed in Physical Chemistry, during the years before his retirement, with some roots which can be traced to the famous Linus Pauling school of the mid 1950s, and made possible, by the work of many students (especially Donatella Carbonera and Marilena Di Valentin) and of an older associate (Giancarlo Agostini). The group participated quite actively with a number of European and American laboratories in the application of physical techniques, especially Electron Spin Resonance (EPR) associated with Optical Spectroscopy (Optically Detected Magnetic Resonance; ODMR), and contributed to the development of the understanding of the structure-function relationships in photosynthetic membrane complexes, stimulated by the determination of the X-ray structure of the purple photosynthetic reaction center in the mid 1980s ( J. Deisenhofer, H. Michel, R. Huber and others). The younger brother of Giovanni, Giorgio Mario Giacometti, came to Padova after obtaining biochemical knowledge from the Rossi-Fanelli school in Rome, where Jeffries Wyman, Eraldo Antonini and Maurizio Brunori were the world masters of hemoglobin research. In Padova, together with a group of young scientists (at first Roberto Bassi and Roberto Barbato, now leaders of their own groups in Verona and in Alessandria respectively, followed soon by brilliant coworkers such as Fernanda Rigoni, Elisabetta Bergantino and more recently Ildikò Szabò and Paola Costantini), Giorgio approached more biochemical themes of oxygenic photosynthesis, such as purification and characterization

Coupling Fluid and Kineitc Effects in Space Weather: an interdisciplinary task

Lapenta, Giovanni; González-Herrero, Diego; Boella, Elisabetta; Siddi, Lorenzo; Cazzola, Emanuele

2017-04-01

Two agents are key to space weather: electromagentic fields and energetic particles. Magnetic fields carried by plasmas in the solar wind interact with the Earth magnetosphere and solar energetic particles produced by solar events or in cosmic rays affect the space environment. Describing both is challenging. Magnetized plasmas are most effectively described by magneto-hydrodynamics, MHD, a fluid theory based on describing some fields defined in space: electromagnetic fields, density, velocity and temperature of the plasma. High energy particles, instead need a more detailed approach , kinetic theory, where statistical distributions of particles are governed by the Boltzmann equation. While fluid models are based on the ordinary space and time, kinetic models require a six dimensional space, called phase space, besides time. The two methods are not separated, the processes leading to the production of energetic particles are the same that involve space plasamas and fields. Arriving at a single self-consistent model has been the goal of the Swiff project funded by the EC in FP7 and it is now a key goal of the ongoing DEEP-ER project. We present a new approach developed with the goal of extending the reach of kinetic models to the fluid scales. Kinetic models are a higher order description and all fluid effects are included in them. However, the cost in terms of computing power is much higher and it has been so far prohibitively expensive to treat space weather events fully kinetically. We have now designed a new method capable of reducing that cost by several orders of magnitude making it possible for kinetic models to study space weather events [1,2]. We will report the new methodology and show its application to space weather mdeling.

Coherent Uncertainty Analysis of Aerosol Measurements from Multiple Satellite Sensors

2013-01-01

Aerosol retrievals from multiple spaceborne sensors, including MODIS (on Terra and Aqua), MISR, OMI, POLDER, CALIOP, and SeaWiFS altogether, a total of 11 different aerosol products were comparatively analyzed using data collocated with ground-based aerosol observations from the Aerosol Robotic Network (AERONET) stations within the Multi-sensor Aerosol Products Sampling System (MAPSS, http://giovanni.gsfc.nasa.gov/mapss/ and http://giovanni.gsfc.nasa.gov/aerostat/). The analysis was performed by comparing quality-screened satellite aerosol optical depth or thickness (AOD or AOT) retrievals during 2006-2010 to available collocated AERONET measurements globally, regionally, and seasonally, and deriving a number of statistical measures of accuracy. We used a robust statistical approach to detect and remove possible outliers in the collocated data that can bias the results of the analysis. Overall, the proportion of outliers in each of the quality-screened AOD products was within 12%. Squared correlation coefficient (R2) values of the satellite AOD retrievals relative to AERONET exceeded 0.6, with R2 for most of the products exceeding 0.7 over land and 0.8 over ocean. Root mean square error (RMSE) values for most of the AOD products were within 0.15 over land and 0.09 over ocean. We have been able to generate global maps showing regions where the different products present advantages over the others, as well as the relative performance of each product over different landcover types. It was observed that while MODIS, MISR, and SeaWiFS provide accurate retrievals over most of the landcover types, multi-angle capabilities make MISR the only sensor to retrieve reliable AOD over barren and snow / ice surfaces. Likewise, active sensing enables CALIOP to retrieve aerosol properties over bright-surface shrublands more accurately than the other sensors, while POLDER, which is the only one of the sensors capable of measuring polarized aerosols, outperforms other sensors in

In 1930, Italian psychiatrist Giovanni Enrico Morselli described the history, diagnosis, and treatment of his patient Elena. The case of Elena has been considered in literature as one of the most remarkable cases of multiple personality ever published. In fact, before treatment, Elena showed alternating French- and Italian-speaking personalities, with the Italian personality knowing nothing of her French counterparts. After a difficult treatment involving recovered memories of incestuous attacks by her father, which were proven to be true, Elena fully recovered from her symptoms. In this article, the author presents details of the case that were not available in the international literature before. He also discusses Elena's psychological and somatoform symptoms according to a contemporary perspective on the relationally traumatic origins of dissociation and dissociative identity disorder.

The association between hearing impairment, the diagnosis of dementia, and the role of sensory therapy has been proposed for some time, but further research is needed. Current understanding of this association requires the commitment of those experts who can integrate experience and research from several fields to be able to understand the link from hearing to dementia. A workshop whose panelists included experts from many areas, ranging from ear, nose and throat (ENT) to dementia's specialists, was promoted and organized by the Giovanni Lorenzini Medical Science Foundation (Milan, Italy; Houston, TX, USA) to increase the awareness of the relationship between hearing loss and dementia, and included questions and comments following a presentation from the clinical researcher, Frank Lin, who has been evaluating the relationship between hearing loss and cognitive decline since 2009.

Multidisciplinary studies on ancient sandstone quarries of Western Sardinia (Italy).

The ancient coastal quarries of Mediterranean are increasingly considered geosites of multidisciplinary relevance. They are sites of historical-archaeological interest that show ancient techniques of stone extraction; they are significant for cultural heritage conservation and restoration, as sources of the stones used in ancient buildings and monuments; they are sites of geological relevance, as often retain important stratigraphic sections; they are also useful markers of secular changes in the sea level. A multisciplinary study is in progress on the ancient quarries of the Sinis region (western Sardinia island), integrating archaeological, geological, minero-petrographical data. In Sardinia, coastal quarries have been established from Punic and Roman times. Many of them exploited Quaternary sediments along the southern and western coasts of the island. They consist of middle-late Pleistocene marine conglomerates and carbonate sandstones, and of coastal (aeolian) carbonate sandstones. Sandstone blocks of different sizes have been widely used in ancient cities for buildings, defensive works, harbours, etc. Three main areas of stone extraction (San Giovanni di Sinis, Punta Maimoni, Is Arutas) have been so far recognized in the Sinis. GIS-supported mapping and documentation of the sites includes their geology and stratigraphy, the extension and layout of the quarries, and an evaluation of volumes of extracted rocks. Documented archaeological evidences include ancient extraction fronts, spoil heaps, working areas, working traces in the old fronts, transport routes of blocks, and traces of loading facilities. The study is aimed at reconstructing the relationships of the quarries with the urban areas of Sinis, as the ancient Punic-Roman city of Tharros. Consequently, a minero-petrographical characterization (optical microscopy, XRD) is performed on sandstones sampled in each quarry, and in historical buildings in Tharros and other centres of the region (Cabras

Medical semiotics; its influence on art, psychoanalysis and Sherlock Holmes.

Semiotics is the analysis and interpretation of signs and the basis of medicine since antiquity. It is suggested that the growth of technology has led to the virtual eclipse of the clinical examination with consequent loss of skill, empathy and patient trust. This paper views the value of medical semiotics through the method of the 19th century Italian doctor, Giovanni Morelli, which has had a significant but little recognised impact on the early development of psychoanalysis, the detective novel and art connoisseurship. Semiotics and, specifically, the linguistic semiotics of Ferdinand Saussure have been influential in the fields of the visual arts, literature and the social sciences since the 20th century. With its roots in the medical treatises of antiquity, medical semiotics should again be brought to the forefront of medical practice. © The Author(s) 2014.

His particular interests centered on issues related to comparison and harmonization of several aspects of aerosol data, such as data quality, bias adjustment, and data provenance. A thorough understanding of these issues is needed to guide multi-sensor data usage and avoid apples-to-oranges inter-comparison and data fusion. In this talk, I will highlight these activities/projects. These would include the tools developed, but also the projects that address specific user needs and innovative services, such as GIOVANNI-MAPSS, AeroStat, NEESPI, MAIRS, ATDD, MDSA, LTA-SWDB, etc. I will also discuss preliminary results from new projects and future goals that build on the ground breaking work, left by Dr. Leptoukh.

Rutilio Staderini was one of the leading Italian anatomists of the twentieth century, together with some scientists, such as Giulio Chiarugi, Giovanni Vitali, and others. He was also a member of a new generation of anatomists. They had continued the tradition of the most famous Italian scientists, which started from the Renaissance up until the nineteenth century. Although he carried out important studies of neuroanatomy and comparative anatomy, as well as embryology, his name is rarely remembered by most medical historians. His name is linked to the nucleus he discovered: the Staderini nucleus or intercalated nucleus, a collection of nerve cells in the medulla oblongata located lateral to the hypoglossal nucleus. This article focuses on the biography of the neuroanatomist as well as the nucleus that carries his name and his other research, especially on comparative anatomy and embryology.

Data Reorganization for Optimal Time Series Data Access, Analysis, and Visualization

The way data are archived is often not optimal for their access by many user communities (e.g., hydrological), particularly if the data volumes and/or number of data files are large. The number of data records of a non-static data set generally increases with time. Therefore, most data sets are commonly archived by time steps, one step per file, often containing multiple variables. However, many research and application efforts need time series data for a given geographical location or area, i.e., a data organization that is orthogonal to the way the data are archived. The retrieval of a time series of the entire temporal coverage of a data set for a single variable at a single data point, in an optimal way, is an important and longstanding challenge, especially for large science data sets (i.e., with volumes greater than 100 GB). Two examples of such large data sets are the North American Land Data Assimilation System (NLDAS) and Global Land Data Assimilation System (GLDAS), archived at the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC; Hydrology Data Holdings Portal, http://disc.sci.gsfc.nasa.gov/hydrology/data-holdings). To date, the NLDAS data set, hourly 0.125x0.125° from Jan. 1, 1979 to present, has a total volume greater than 3 TB (compressed). The GLDAS data set, 3-hourly and monthly 0.25x0.25° and 1.0x1.0° Jan. 1948 to present, has a total volume greater than 1 TB (compressed). Both data sets are accessible, in the archived time step format, via several convenient methods, including Mirador search and download (http://mirador.gsfc.nasa.gov/), GrADS Data Server (GDS; http://hydro1.sci.gsfc.nasa.gov/dods/), direct FTP (ftp://hydro1.sci.gsfc.nasa.gov/data/s4pa/), and Giovanni Online Visualization and Analysis (http://disc.sci.gsfc.nasa.gov/giovanni).

This disorder, while uncommon, is an important multiple congenital anomaly and dysplasia syndrome; the causative gene was recently identified. This paper is a seminal work and is graciously republished by Wiley-Blackwell in the Special Festschrift issue honoring Professor Neri. We describe a familial syndrome of renal dysplasia, Wilms tumor, hyperplasia of the endocrine pancreas, fetal gigantism, multiple congenital anomalies and mental retardation. This condition was previously described by Perlman et al. [1973, 1975] and we propose to call it the "Perlman syndrome." It appears to be transmitted as an autosomal recessive trait. The possible relationships between dysplasia, neoplasia and malformation are discussed. © 2013 Wiley Periodicals, Inc.

[Pinocchio and the unattained identity: Jervis' contribution to child clinical psychology].

PubMed

Meacci, Stefano

2012-01-01

Giovanni Jervis is mainly known as a psychiatrist, but he also worked on psychological methodology and tackled important issues in clinical psychology. This essay describes the concept of personal identity elaborated by Jervis and its importance in Child Clinical Psychology. The problems related to personal identity appear very early in Jervis' work, influenced by the ethnologist Ernesto De Martino. His first considerations are found in his Preface to The Adventures of Pinocchio by Carlo Collodi (1968), in which Jervis describes the unhappy upbringing, the anti-social behaviour, and the unattained identity of the wooden puppet. Subsequently, in Presenza e identith (1984), Fondamenti di Psicologia Dinamica (1993) and La conquista dell'identith (1997), Jervis dealt with the theme of identity from a Dynamic Psychology perspective, showing that the formation of personal identity is a basic aspect of the development of the individual that starts in early childhood.

There is still uncertainty about the diagnosis and nature of the plague; some scholars have been forced to abandon certainties and be filled with doubts: from believing that the mediaeval Black Plague was, in reality, the bubonic plague (although with unusual characteristics) to stating that there is very little evidence to support a retro-diagnosis. This article looks at this in depth, not only reviewing the historiography but also giving new interpretations which question previous hypotheses through research on images of the time, comparing them to the most recent investigative data. Two primary sources are analysed: Renaissance treaties written by four Italian doctors: Michele Savonarola, Marsilio Ficino, Leonardo Fioravanti and Gioseffo Daciano; and iconography: an illustrated manuscript of the Decameron by Giovanni Boccaccio and a Hebrew Haggadah from the XIVth century. The results are compared to the most recent research on DNA and in micropaleontology.

Analysis of spatial and temporal variations of sulfur dioxide concentration in planetary boundary layer were conducted. The data were generated by NASA satellite daily from October of 2004 and were obtained through NASA Giovanni. The global monthly mean spatial distribution of sulfur dioxide showed several hot spots including: several spots on some islands in the Pacific Ocean, several spots in central America, and central Africa. Most of these hot spots of sulfur dioxide are related to known active volcanos. The biggest hot spot of sulfur dioxide were observed in Northeastern China. While high concentration sulfur dioxide was still observed in Northeastern China in 2017. The area averaged concentration of sulfur dioxide declined dramatically since its peak in 2008. This temporal trend indicates that sulfur reduction effort has been effective in the last decade or post 2008 financial crisis recovery lead an industry less sulfur dioxide emission.

Red, White and Black: Colors of Beauty, Tints of Health and Cosmetic Materials in Early Modern English Art Writing.

PubMed

Sammern, Romana

2015-01-01

Alongside Richard Haydocke's translation of Giovanni Paolo Lomazzo's treatise on painting (1598), the article examines concepts of color concerning cosmetics, painting and complexion as they relate to aesthetics, artistic and medical practice in the sixteenth and seventeenth centuries. Beginning with white and red as ideal colors of beauty in Agnolo Firenzuola's Discourse on the beauty of women (1541), the essay places color in relation to major issues in art, medicine and empiricism by discussing beauty as a quality of humoral theory and its colors as visual results of physiological processes. Challenging the relation of art and nature, gender and production, Lomazzo's account of complexion and Haydocke's additions on cosmetic practices and face-painting provide key passages that shed light on the relation of cosmetics colors, art writing and artistic practices at the convergence of the body, art and medicine in the context of the emerging English virtuosi around 1600.

[Christian Wisbech--his hospital and surgery in the 1820s].

Janssen, C W

1993-12-10

Christian Wisbech (1801-1869) was medical superintendent of "Bergen civile Sygehus" during the period 1825-1848. Some of his annual reports have been published. The hospital had 56 beds. The permanent staff included one "spisemester" (caterer) and two "sygeopvartersker" (nurses). Christian Wisbech's medicine was based on strict scientific principles and pathological anatomy. A post-mortem was performed on the deceased. Other current trends in medical practice at that time were foreign to him. It is assumed that he was inspired by Giovanni Morgagni (1682-1771) and John Hunter (1728-1793). His treatment was partly medical and partly surgical. Wisbech treated surprisingly few injuries. A possible explanation is the large number of "barbers and surgeons" in Bergen at that time. It was probably a centuries-long tradition among the population to go to such persons to be treated for broken bones, wounds and other complaints.

Ziegler, J

1995-01-01

By the beginning of the fourteenth century, medicine had acquired a cultural role in addition to its traditional function as a therapeutic art. Medical subject matter infiltrated the religious discourse via the new thirteenth-century encyclopedic literature. Preachers came to employ in their moral analogies a wider range of medical topics, using sophisticated medical examples and citations attributed to recognized medical authorities. These developments coincided with the growing prestige of medicine as an academic discipline.

Observing Mars with Schiaparelli's telescope

2004-03-01

We have taken the occasion of the 2003 Mars' opposition to carry out observations of the red planet with the 218 mm Merz refractor, built in the 1863-1865, recently restored, used by Giovanni Virginio Schiaparelli to observe Mars from the opposition of August 1877 until that one of the 1883-'84. In the occasion we launched a 5 days initiative of dissemination of scientific culture addressed to students and public at large. We organized direct observations and adapted a webcam to the ancient instrument. The images were sent to Milanese Planetarium where about 300 people, every night, could participate to the manifestation. Moreover a big screen was arranged in the garden around the Planetarium in order to allow other people to participate. The projection of the images was part of a 2 hours program of short lectures on the historical and current aspects of Mars. This initiative was successful: but what about scientific culture? What kind of scientific information did the public perceive?

A scholarly intermediary between the Ottoman Empire and Renaissance Europe.

Morrison, Robert

2014-03-01

This essay studies Moses Galeano, a Jewish scholar with ties to Crete and the Ottoman Sultan's court, who traveled to the Veneto around 1500. After describing Galeano's intellectual milieu, it focuses, first, on circumstantial evidence that he transmitted information central to the rise of Renaissance astronomy. Galeano knew of theories that strongly resemble portions of astronomy texts written by Giovanni Battista Amico and Girolamo Fracastoro at Padua a few decades later. He also knew about theories pioneered by the Damascene Ibn al-Shāţir (d. 1375) that strongly resemble portions of Copernicus's work. Next, the article turns to concrete evidence showing that Galeano was part of a network of Jewish scholars who did have contact with Christian scholars in Europe. The essay concludes that, while it is impossible to prove that Galeano had direct contact with Copernicus, he most likely had contact with some European astronomer(s) in the Veneto.

A Hanged From the Past: Medical Consideration on the Judas Iscariot Fresco-Chapelle Notre-Dame-des-Fontaines, La Brigue (15th Century).

The medieval chapel of Notre Dame-des-Fontaines (Our Lady of the Fountains), in the French Maritime Alps, is entirely covered by the fresco cycle of the Passion (15th century) that depicts the last days of Jesus from the Last Supper to the Resurrection. Under a small window, there is the brutal representation of the suicide of Judas Iscariot, hanging from a tree, with the abdomen quartered from which his soul, represented by a small man, is kidnapped by a devil. The author, Giovanni Canavesio, represented the traitor's death with very detailed anatomical structures, differently thus from other paintings of the same subject; it is therefore possible to assume that the artist had become familiar with the human anatomy. In particular, the realism of the hanged man's posture, neck bent in an unnatural way, allows us to hypothesize that it probably comes from direct observation of the executions of capital punishment, not infrequently imposed by the public authorities in low medieval Italy.

2016-01-01

Unified User Interface (UUI) is a next-generation operational data access tool that has been developed at Goddard Earth Sciences Data and Information Services Center(GES DISC) to provide a simple, unified, and intuitive one-stop shop experience for the key data services available at GES DISC, including subsetting (Simple Subset Wizard -SSW), granule file search (Mirador), plotting (Giovanni), and other legacy spatial data services. UUI has been built based on a flexible infrastructure of reusable web services self-contained building blocks that can easily be plugged into spatial applications, including third-party clients or services, to easily enable new functionality as new datasets and services become available. In this presentation, we will discuss our experience in designing UUI services based on open industry standards. We will also explain how the resulting framework can be used for a rapid development, deployment, and integration of spatial data services, facilitating efficient access and dissemination of spatial data sets.

Schiaparelli and his legacy

Manara, A.; Trinchieri, G.

Giovanni Virginio Schiaparelli has been one of the most important Italian astronomers of the eighteen hundreds. He was an active scientist and the director of the Brera Observatory for close to 40 years; his scientific achievements and his personal influence can be traced to a very large community of people and subjects, which go well beyond the observations of Mars, for which he is most famous. His vast range of interests, which include studies on history of Astronomy and ancient languages, Solar System bodies, meteorology, and Earth sciences, are well documented and will be the reviewed in this conference. More relevant to modern science, he has left us a very solid legacy, both with his pioneering scientific works, now progressing with new discoveries and the aid of new technology, and with the consequences of his observations of Mars, which have greatly influenced the literary world and have opened new research activities in medicine.

Giovanni Pico della Mirandola and Angelo Poliziano were two of the most important humanists of the Italian Renaissance. They died suddenly in 1494 and their deaths have been for centuries a subject of debate. The exhumation of their remains offered the opportunity to study the cause of their death through a multidisciplinary research project. Anthropological analyses, together with documentary evidences, radiocarbon dating and ancient DNA analysis supported the identification of the remains attributed to Pico. Macroscopic examination did not reveal paleopathological lesions or signs related to syphilis. Heavy metals analysis, carried out on bones and mummified tissues, showed that in Pico's remains there were potentially lethal levels of arsenic, supporting the philosopher's poisoning theory reported by documentary sources. The arsenic concentrations obtained from analysis of Poliziano's remains, are probably more related to an As chronic exposure or diagenetic processes rather than poisoning.

Purpose of the present note is to assess the risk from Whole-body vibration (WBV) in operators employed in the shunting of engines within the railway stations. The study has been conducted in the cockpits of the shunting engines used within the railway station of Villa S. Giovanni (RC). The measures have been taken through accelerometer IHVM 100 Larson-Davis, placed on the seat of each locomotives for a recording time of around 15 minutes. A standard measure has been effected besides, positioning the sensor on the floor of the same locomotives. The measurements indicate that the risk to these workers is negligible because in any case the value is exceeded action daily 0.5 m/s2, having recorded values range from 0.1 to 0.2 m / s2. In conclusion it holds him necessary, to the preventive goals, in respect to how much anticipated from the D.L.gs 187/05 the necessary technical, organizational and formative measures to the containment of the risk.

Normal modes of oscillation of the Asinelli and Garisenda towers in Bologna (Italy)

Morelli, A.; Azzara, R. M.; Cavaliere, A.; Zaccarelli, L.

2013-12-01

The Asinelli and Garisenda medieval towers represent the best-know city landmark in Bologna. Asinelli is also known to physics historians for early experiments on free fall of bodies for the first measurements of g (Giovanni Battista Riccioli, ca. 1650) and proof of Earth rotation (Giovanni Battista Guglielmini, 1791). The Two Towers (as they are commonly known) are essentially tall, square cross-section hollow masonry cuboids. Taller Asinelli, built between 1109 and 1119, is 97 m high, with an overhang of 2.2 m, while more seriously leaning Garisenda has an overhang of 3.2 m with a heigth of 48 m. During the summer of 2012 -- in the aftermath of two M≈6 earthquakes occurred in the proximity of the city -- the permanent engineering monitoring system of the towers has been temporarily supplemented by 6 seismometric stations installed at different levels inside the masonry buildings, to study their dynamical response to induced vibrations. We have thus been able to observe and measure the oscillation of the two towers excited by ambient noise, mostly due to city traffic. The two towers show similar behaviour, more clear in taller Asinelli. The first three flexural normal modes of oscillation, and the first torsional mode, can easily be detected. Their frequencies are split because of the asymmetry due to leaning of the tower. This asymmetry produces slightly different frequencies of oscillation in two orthogonal directions, quite consistent with preliminary dynamical modeling. Horizontal particle-motion polarization plots clearly show the cyclic energy transfer between these two degrees of freedom of the system. Oscillations of taller Asinelli influence its close sister, such that the Asinelli spectral signature can also be easily recognized in the motion recorded at the base of Garisenda, overimposed over Garisenda own free oscillations. Horizontal component polarization analysis done simultaneously at the two ground-level stations often point to a nearby common

Precipitation is an important dataset in hydrometeorological research and applications such as flood modeling, drought monitoring, etc. On February 27, 2014, the NASA Global Precipitation Measurement (GPM) mission was launched to provide the next-generation global observations of rain and snow (http:pmm.nasa.govGPM). The GPM mission consists of an international network of satellites in which a GPM Core Observatory satellite carries both active and passive microwave instruments to measure precipitation and serve as a reference standard, to unify precipitation measurements from a constellation of other research and operational satellites. The NASA Goddard Earth Sciences (GES) Data and Information Services Center (DISC) hosts and distributes GPM data. The GES DISC is home to the data archive for the GPM predecessor, the Tropical Rainfall Measuring Mission (TRMM). GPM products currently available include the following:1. Level-1 GPM Microwave Imager (GMI) and partner radiometer products2. Goddard Profiling Algorithm (GPROF) GMI and partner products (Level-2 and Level-3)3. GPM dual-frequency precipitation radar and their combined products (Level-2 and Level-3)4. Integrated Multi-satellitE Retrievals for GPM (IMERG) products (early, late, and final run)GPM data can be accessed through a number of data services (e.g., Simple Subset Wizard, OPeNDAP, WMS, WCS, ftp, etc.). A newly released Unified User Interface or UUI is a single interface to provide users seamless access to data, information and services. For example, a search for precipitation products will not only return TRMM and GPM products, but also other global precipitation products such as MERRA (Modern Era Retrospective-Analysis for Research and Applications), GLDAS (Global Land Data Assimilation Systems), etc.New features and capabilities have been recently added in GIOVANNI to allow exploring and inter-comparing GPM IMERG (Integrated Multi-satelliE Retrievals for GPM) half-hourly and monthly precipitation

In 1765 Giovanni Morgagni described a syndrome consisting of hyperostosis frontalis interna (HFI), obesity and hirsutism. In 1928 Stewart and in 1930 Morel added neuropsychiatric symptoms, e.g. depression and dementia, which led to the definition of the Morgagni-Stewart-Morel Syndrome (MSM). Although mostly women were characterized in literature no gender specifity is demanded. This case report presents the rare case of a 66 year old male psychiatric patient with Morgagni-Stewart-Morel Syndrome. The patient complained of loss of concentration and difficulties with activities of daily living. Admission diagnosis was an opioid misuse on the basis of a chronic pain syndrome. In this case report we are describing clinical features, the patient history and technical (MRI) and neuropsychological tests. Although severe psychiatric symptoms and neuropsychological deficits are commonly seen in these patients, our patient showed only mild symptoms. This case reports shows the possibility of a male patient with MSM. If MSM is a separate entity or just an epiphenomena of hormone dysregulation should be investigated in further studies.

Michelangelo's eye disease.

Charged by the Pope Julius II for painting the Cappella Sistina in Rome (between 1508 and 1512), Michelangelo worked in an elevated scaffolding, in an anomalous position with dyes (including poisoning lead salts) and solvents (such as toxic turpentine) dripping on his face and continuously inhaling, in a dim environment illuminated only with oil lamps and candles, as he described himself and sketched in a sonet addressed to Giovanni da Pistoia. In 1510 he began suffering from eye disease: the main symptom was the necessity to elevate the document he was reading up to the level of his eyes. This defect disappeared few months after he finished painting his masterpiece. We hypothesize that the Michelangelo's eyes disease was a form of acquired and transitory nystagmus induced by the many hours he spent in up gaze, with a skew deviation, a form of ocular tilt reaction resulting from the impairment of spatial sensitivity (inversion illusion) due to the persistence of the artist's head in a horizontal position, looking upward.

2006-01-01

• Background The gorgeous frescoes organized by the master Renaissance painter Raphael Sanzio (1483–1520) and illustrating the heavenly adventures of Cupid and Psyche were painted between 1515 and 1518 to decorate the Roman villa (now known as the Villa Farnesina) of the wealthy Sienese banker Agostino Chigi (1466–1520). Surrounding these paintings are festoons of fruits, vegetables and flowers painted by Giovanni Martini da Udine (1487–1564), which include over 170 species of plants. A deconstruction and collation of the cucurbit images in the festoons makes it possible to evaluate the genetic diversity of cucurbits in Renaissance Italy 500 years ago. • Findings The festoons contain six species of Old World cucurbits, Citrullus lanatus (watermelon), Cucumis melo (melon), Cucumis sativus (cucumber), Ecballium elaterium (squirting cucumber), Lagenaria siceraria (bottle gourd) and Momordica balsamina (balsam apple), and two or three species of New World cucurbits, Cucurbita maxima, C. pepo and, perhaps, C. moschata (pumpkin, squash, gourd). The images of C. maxima are the first illustrations of this species in Europe. PMID:16314340

The 1761 transit of Venus dispute between Audiffredi and Pingré

2005-04-01

On 6 June 1761 the Dominican Giovanni Battista Audiffredi observed the transit of Venus in his little observatory at the Monastery of Santa Maria sopra Minerva in Rome. Soon after, he published an anonymous short report in Italian, and in the first months of 1762 he published a complete Latin essay about his transit observations. Late in 1762, and in 1765, the French abbé Alexandre-Gui Pingré, who had observed the transit at the Rodriguez Isle, to the south of the equator, presented to the French Royal Academy of Sciences the results of the solar parallax determination derived from comparison of observations made in different geographic places. He had excluded the Roman data because - he said - of the lack of a fundamental quantity, the longitude of the Monastery, concluding that the Roman observations were imperfect. In order to defend his scientific reputation, Audiffredi published two Latin essays concerning the solar parallax determination, the Investigatio parallaxis solaris in 1765, and the De Solis parallaxis Commentarius in 1766.

The implicit Particle-in-Cell method for the computer simulation of space plasma, and its im-plementation in a three-dimensional parallel code, called iPIC3D, are presented. The implicit integration in time of the Vlasov-Maxwell system removes the numerical stability constraints and enables kinetic plasma simulations at magnetohydrodynamics scales. Simulations of mag-netic reconnection in plasma are presented to show the effectiveness of the algorithm. In particular we will show a number of simulations done for large scale 3D systems using the physical mass ratio for Hydrogen. Most notably one simulation treats kinetically a box of tens of Earth radii in each direction and was conducted using about 16000 processors of the Pleiades NASA computer. The work is conducted in collaboration with the MMS-IDS theory team from University of Colorado (M. Goldman, D. Newman and L. Andersson).

Spatial Aspects of Multi-Sensor Data Fusion: Aerosol Optical Thickness

NASA Technical Reports Server (NTRS)

Leptoukh, Gregory; Zubko, V.; Gopalan, A.

2007-01-01

The Goddard Earth Sciences Data and Information Services Center (GES DISC) investigated the applicability and limitations of combining multi-sensor data through data fusion, to increase the usefulness of the multitude of NASA remote sensing data sets, and as part of a larger effort to integrate this capability in the GES-DISC Interactive Online Visualization and Analysis Infrastructure (Giovanni). This initial study focused on merging daily mean Aerosol Optical Thickness (AOT), as measured by the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the Terra and Aqua satellites, to increase spatial coverage and produce complete fields to facilitate comparison with models and station data. The fusion algorithm used the maximum likelihood technique to merge the pixel values where available. The algorithm was applied to two regional AOT subsets (with mostly regular and irregular gaps, respectively) and a set of AOT fields that differed only in the size and location of artificially created gaps. The Cumulative Semivariogram (CSV) was found to be sensitive to the spatial distribution of gap areas and, thus, useful for assessing the sensitivity of the fused data to spatial gaps.

NASA Earth Sciences Division (ESD) has made great investments in the development and maintenance of data management systems and information technologies, to maximize the use of NASA generated Earth science data. With information management system infrastructure in place, mature and operational, very small delta costs are required to fully support data archival, processing, and data support services required by the recommended Decadal Study missions. This presentation describes the services and capabilities of the Goddard Space Flight Center (GSFC) Earth Sciences Data and Information Services Center (GES DISC) and the reusability for these future missions. The GES DISC has developed a series of modular, reusable data management components currently in use. They include data archive and distribution (Simple, Scalable, Script-based, Science [S4] Product Archive aka S4PA), data processing (S4 Processor for Measurements aka S4PM), data search (Mirador), data browse, visualization, and analysis (Giovanni), and data mining services. Information management system components are based on atmospheric scientist inputs. Large development and maintenance cost savings can be realized through their reuse in future missions.

2015-09-01

Following Giovanni Berlinguer's proposal that health/disease processes are one of the primary spies into the contradictions of a system, this article describes cases that occurred in central and peripheral capitalist contexts as well as in the so-called "real socialist" States that allow such a role to be seen. Secondly, we observe the processes and above all the interpretations developed in Latin America and especially Mexico regarding the role attributed to traditional medicine in the identity and sense of belonging of indigenous peoples, which emphasize the incompatibility of indigenous worldviews with biomedicine. To do so we analyze projects that were carried out under the notion of intercultural health, which in large part resulted in failure both in health and political terms. The almost entirely ideological content and perspective of these projects is highlighted, as is the scant relationship they hold with the reality of indigenous people. Lastly, the impact and role that the advance of these conceptualizations and health programs might have had in the disengagement experienced over the last nearly ten years in the ethnic movements of Latin America is considered.

We report a case of neuroleptic malignant syndrome in a woman who assumed risperidone for schizoaffective disorders. A 45-year-old woman affected by schizoaffective disorders was admitted to Infectious Disease unit of Crotone Hospital because of a diagnosis of a fever of unknown origin. Clinical evaluation documented confusion and dysphoria, whereas chemical blood evaluation revealed acidosis and liver dysfunction. After few days she was transferred to the Operative Unit of Internal Medicine of San Giovanni in Fiore Hospital because of an increase in liver transaminases. Clinical evaluation showed the persistence of fever (38.8 degrees Celsius), with an increase in CPK, and liver enzymes. Pharmacological evaluation indicated a probable relationship between risperidone and NMS and led to a diagnosis of neuroleptic malignant syndrome associated with risperidone in a woman with schizophrenia. About seven days later, we recorded a complete resolution of her psychiatric symptoms. We postulate a possible interaction between risperidone and neuroleptic malignant syndrome and we suggest to use risperidone with caution in both young and middle aged people.

Over the past 12 years, large volumes of precipitation data have been generated from space-based observatories (e.g., TRMM), merging of data products (e.g., gridded 3B42), models (e.g., GMAO), climatologies (e.g., Chang SSM/I derived rain indices), field campaigns, and ground-based measuring stations. The science research, applications, and education communities have greatly benefited from the unrestricted availability of these data from the Goddard Earth Sciences Data and Information Services Center (GES DISC) and, in particular, the services tailored toward precipitation data access and usability. In addition, tools and services that are responsive to the expressed evolving needs of the precipitation data user communities have been developed at the Precipitation Data and Information Services Center (PDISC) (http://disc.gsfc.nasa.gov/precipitation or google NASA PDISC), located at the GES DISC, to provide users with quick data exploration and access capabilities. In recent years, data management and access services have become increasingly sophisticated, such that they now afford researchers, particularly those interested in multi-data set science analysis and/or data validation, the ability to homogenize data sets, in order to apply multi-variant, comparison, and evaluation functions. Included in these services is the ability to capture data quality and data provenance. These interoperability services can be directly applied to future data sets, such as those from the Global Precipitation Measurement (GPM) mission. This presentation describes the data sets and services at the PDISC that are currently used by precipitation science and applications researchers, and which will be enhanced in preparation for GPM and associated multi-sensor data research. Specifically, the GES-DISC Interactive Online Visualization ANd aNalysis Infrastructure (Giovanni) will be illustrated. Giovanni enables scientific exploration of Earth science data without researchers having to

The Telescope: Outline of a Poetic History

NASA Astrophysics Data System (ADS)

Stocchi, M. P.

2011-06-01

Amongst the first editions of Galileo's books, only the Saggiatore has on its frontispiece the image of the telescope. Indeed, the telescope is not pictured on the very emphatic frontispieces of the other books in which Galileo was presenting and defending the results achieved by his celestial observations, such as the Sidereus Nuncius. Many contemporary scientists denied the reliability of the telescope, and some even refused to look into the eyepiece. In the 16th and 17th century, the lenses, mirrors, and optical devices of extraordinary complexity did not have the main task of leading to the objective truth but obtaining the deformation of the reality by means of amazing effects of illusion. The Baroque art and literature had the aim of surprising, and the artists gave an enthusiastic support to the telescope. The poems in praise of Galileo's telescopic findings were quite numerous, including Adone composed by Giovanni Battista Marino, one of the most renowned poets of the time. The Galilean discoveries were actually accepted by the poets as ideologically neutral contributions to the "wonder" in spite they were rejected or even condemned by the scientists, philosophers, and theologians.

Mining Tacitus: secrets of empire, nature and art in the reason of state.

PubMed

Keller, Vera

2012-06-01

A new political practice, the 'reason of state', informed the ends and practices of natural study in the late sixteenth century. Informed by the study of the Roman historian Tacitus, political writers gathered 'secrets of empire' from both history and travel. Following the economic reorientation of 'reason of state' by Giovanni Botero (1544-1617), such secrets came to include bodies of useful particulars concerning nature and art collected by an expanding personnel of intelligencers. A comparison between various writers describing wide-scale collections, such as Botero, Francis Bacon (1561-1626), Jakob Bornitz (1560-1625) and Matthias Bernegger (1582-1640), reveals that seventeenth-century natural intelligencers across Europe not only were analogous to political intelligencers, but also were sometimes one and the same. Those seeking political prudence cast themselves as miners, prying precious particulars from the recesses of history, experience and disparate disciplines, including mathematics, alchemy and natural philosophy. The seventeenth-century practice of combining searches for secrets of empire, nature and art contests a frequent historiographical divide between empirical science and Tacitism or reason of state. It also points to the ways political cunning shaped the management of information for both politics and the study of nature and art.

Volumic visual perception: principally novel concept

NASA Astrophysics Data System (ADS)

Petrov, Valery

1996-01-01

The general concept of volumic view (VV) as a universal property of space is introduced. VV exists in every point of the universe where electromagnetic (EM) waves can reach and a point or a quasi-point receiver (detector) of EM waves can be placed. Classification of receivers is given for the first time. They are classified into three main categories: biological, man-made non-biological, and mathematically specified hypothetical receivers. The principally novel concept of volumic perception is introduced. It differs chiefly from the traditional concept which traces back to Euclid and pre-Euclidean times and much later to Leonardo da Vinci and Giovanni Battista della Porta's discoveries and practical stereoscopy as introduced by C. Wheatstone. The basic idea of novel concept is that humans and animals acquire volumic visual data flows in series rather than in parallel. In this case the brain is free from extremely sophisticated real time parallel processing of two volumic visual data flows in order to combine them. Such procedure seems hardly probable even for humans who are unable to combine two primitive static stereoscopic images in one quicker than in a few seconds. Some people are unable to perform this procedure at all.

In the late Roman Republic period (2nd-1st century BC), in the area of San Giovanni on Elba Island, previously subject to intense extraction of iron ore, a rustic villa was established by Marco Valerio Messalla, a supreme Roman magistrate. The foundations of the walls were discovered and excavated by an archaeological mission. Palaeobotanical analysis of a set of stratigraphic layers was performed. Palynological slides showed remains of palynomorphic and non-pollen objects, while data combined with anthracological investigations confirmed the hypothesis that in the 1st century AD the villa was destroyed by a fire that created a compact crust under which were discovered four broken Roman amphorae containing about five hundred apple seeds. Comparisons of archaeological and fresh seeds from reference collections showed discontinuous morphology except for one group of archaeological samples. DNA was isolated from seeds that had well-preserved embryos in all groups. DNA extracts from archaeological, wild and modern domestic seeds (controls) were amplified by PCR and tested with SSR molecular markers, followed by genome analysis.

Rossi, Sabrina; Giordano, Enrica; Lanciano, Nicoletta

2016-09-01

In this paper we present the Sky on Earth project funded in 2008 by the Italian Ministry of Instruction, Research and University, inside its annual public outreach education program. The project’s goal was to realise a stable and open-access astronomical garden, where children, teachers and citizens could be engaged in investigations about day and night sky phenomena. The project was designed taking into account our prior researches in formal and informal astronomy education. It was realised in the garden of GiocheriaLaboratori, an out-of-school K-6 educational structure of Sesto San Giovanni municipality (near Milan, Italy). Setting and tools were designed with the help of some students of the ‘Altiero Spinelli’ vocational school and their science and technology teachers. Since its installation, the astronomical garden has been used in workshops and open-days, teachers’ preparation courses and research experiences. We might conclude that the Sky on Earth project represents an example of a positive and constructive collaboration between researchers, educators, high school students and teachers. It may also be considered as a potential attempt to face on the well-known gap between research in science education and school practices.

Ground water level, Water storage, Soil moisture, Precipitation Variability Using Multi Satellite Data during 2003-2016 Associated with California Drought

The agricultural market of California is a multi-billion-dollar industry, however in the recent years, the state is facing severe drought. It is important to have a deeper understanding of how the agriculture is affected by the amount of rainfall as well as the ground conditions in California. We have considered 5 regions (each 2 degree by 2 degree) covering whole of California. Multi satellite (MODIS Terra, GRACE, GLDAS) data through NASA Giovanni portal were used to study long period variability 2003 - 2016 of ground water level and storage, soil moisture, root zone moisture level, precipitation and normalized vegetation index (NDVI) in these 5 regions. Our detailed analysis of these parameters show a strong correlation between the NDVI and some of these parameters. NDVI represents greenness showing strong drought conditions during the period 2011-2016 due to poor rainfall and recharge of ground water in the mid and southern parts of California. Effect of ground water level and underground storage will be also discussed on the frequency of earthquakes in five regions of California. The mid and southern parts of California show increasing frequency of small earthquakes during drought periods.

From Romanticism and fiction to reality: Dippel, Galvani, Aldini and “the Modern Prometheus”. Brief history of nervous impulse

PubMed

Mary Wollstonecraft Godwin, better known as Mary Shelley, and her romantic vision of the world gave life to an endless progeny of literacy stories; also originated the myth of the mortal creator who generate life from science. Unexpectedly the history has been considered as a myth, due to acts grounded in facts of certain “truthful;” such were galvanism and the study of the electrical potential in living beings by the two Italian physicians: Luigi Galvani and Giovanni Aldini. Also, is possible to proclaim direct influence on the work by the European folklore surrounding the theologian, alchemist Johann Konrad Dippel and physician who habited the Frankenstein’s Castle from his birth, and further developing the “life elixir.” The similarities between the novel and the life of the three historical figures suggests that Mary Shelley, belonging to a socially graceful and educated class, was aware of the scientific dispute over the understanding of electricity. Shelley’s creative world, full of gothic and romantic hues, shows direct influence of alchemy speaking of the “spark of life” as well as works published by Galvani and Aldini.

In this paper we report the results of a nosocomial infections surveillance system "Laboratory Based". The system started in August 1995 at San Giovanni Hospital, Rome. All the specimens sent to the Microbiology Laboratory have been registered using a computerized input form. 12,204 forms, attributable to patients between 0 and 97 years (median 43 years) resulted evaluable. The global rate of incidence of nosocomial infection was, in the study period, 16 per one thousand person/day. The rate of incidence, when stratified for the medical, surgical and emergency boards, was, respectively, 19 per one thousand person/day in the medical facilities, 15 per one thousand person/day in surgical and 17 per one thousand person/year in emergency facilities. The nosocomial infections incidence correlated well with the age of the patients and the time of bed stay. The bulk of infections were localized to the respiratory apparatus. Localization to urinary apparatus and sepsis follow. The isolated microbes were (38%) gram-negative microbes; the 38% of the isolates are gram-negative microbes and the 24% are Mycetes. Our data validate the surveillance system in a great hospital of Rome metropolitan area.

There is a vast and ever increasing amount of data on the Earth interconnected energy and hydrological systems, available from NASA remote sensing and modeling systems, and yet, one challenge persists: increasing the usefulness of these data for, and thus their use by, the geospatial communities. The Hydrology Data and Information Services Center (HDISC), part of the Goddard Earth Sciences DISC, has continually worked to better understand the hydrological data needs of the geospatial end users, to thus better able to bridge the gap between NASA data and the geospatial communities. This paper will cover some of the hydrological data sets available from HDISC, and the various tools and services developed for data searching, data subletting ; format conversion. online visualization and analysis; interoperable access; etc.; to facilitate the integration of NASA hydrological data by end users. The NASA Goddard data analysis and visualization system, Giovanni, is described. Two case examples of user-customized data services are given, involving the EPA BASINS (Better Assessment Science Integrating point & Non-point Sources) project and the CUAHSI Hydrologic Information System, with the common requirement of on-the-fly retrieval of long duration time series for a geographical point

The fresco by Diego Rivera (1886 to 1957) on the history of cardiology was displayed at the "Instituto Nacional de Cardiología" of Mexico City at the time of inauguration on April 14, 1944. Some of the most important masters of the Padua Medical School were depicted, namely Vesalius, Harvey, and Morgagni. There is a vivid description of the anatomoclinical method introduced by Giovanni Battista Morgagni (1682 to 1771), when he was professor of Theoretical Medicine first and then of Anatomy at the University of Padua (1711 to 1771). By reading Morgagni's De sedibus, we found the case of aortic syphilitic aneurysm that corresponds perfectly with the one represented in Diego Rivera's mural. In the Museum of Pathological Anatomy of the Padua University, an anatomical specimen that displays the same lesion is preserved, and we have performed a computed tomography scan to analyze the state of the heart and aneurysm, thus finding diffuse calcific deposits of aorta and pericardium. In conclusion, in Diego Rivera's fresco the clinicopathologic method of Morgagni is well represented and the case of syphilitic aneurysm, reported by Morgagni in his De sedibus, depicted.

The term "craniomandibular disorder" is used to describe a series of symptoms and signs that directly affect the stomatognathic apparatus with possible repercussions on the otovestibular and oculomotor apparatus and on the cervical spine that may condition the entire body posture. The aim of this study was to evaluate a series of parameters correlated to the occlusal situation and to verify how these factors are affected by a change following the correction of occulusal ratios. The paper reports a series of 15 patients suffering from facial dysmorphia treated surgically in the Division of Maxillofacial Surgery of S. Giovanni Battista Hospital in Turin in which an evaluation was made of posture and symptoms linked to craniomandibular disorders before surgery and six months after. At the preoperative evaluation a high incidence of this type of symptoms and signs was observed, and in particular a high percentage of patients with postural imbalance and asymmetry of the frontal body segments. From the results obtained it emerges that the surgical re-adaptation of occlusion is followed by esthetic improvement and also by a good recovery of frontal postural symmetry in conformity with the reduced frequency and intensity of symptoms classified as craniomandibular disorders.

Padua: the renaissance of human anatomy and medicine.

The city and University of Padua have a long tradition and a great reputation in anatomic studies, dating from the founding of the university in the year 1222. We present a historical review of the study of human anatomy, for which Padua was a most important center. The background for the development of this culture was represented by the scientific freedom and political wisdom of the Serenissima Republic of Venice, a liberal and tolerant state in the midst of a feudal, imperial, and pontifical Europe. During the second half of the 15th century, the flourishing trade and cultural, social, and political life of Venice attracted a great number of scientists and students from all over Europe who contributed to the establishment of Padua as an international center for culture and the sciences. Vesalio, Fabrizio d'Acquapendente, and Giovanni Battista Morgagni represent milestones in the history of anatomy as well as in medicine and surgery. History shows that anatomy and surgery evolved together, just as anatomy of the nervous system and neurosurgery developed in tandem. The tradition of neurosurgery in Padua is considered one the most important schools in Italy.

The history of gait analysis before the advent of modern computers.

Baker, Richard

Aristotle (384-322 BCE) can be attributed with the earliest recorded comments regarding the manner in which humans walk. It was not until the renaissance that further progress was made through the experiments and theorising of Giovanni Borelli (1608-1679). Although several scientists wrote about walking through the enlightenment period it was the brothers Willhelm (1804-1891) and Eduard (1806-1871) Weber, working in Leipzig who made the next major contribution based on very simple measurements. Both Jules Etienne Marey (1830-1904), working in France, and Eadweard Muybridge (1830-1904), working in America, made significant advances in measurement technology. These were developed further by Otto Fischer (1861-1917) in collaboration with Willhelm Braune (1831-1892). The major developments in the early twentieth century were in the development of force plates and the understanding of kinetics. The team headed by Verne Inman (1905-1980) and Howard Eberhart (1906-1993) made major advances in America shortly after the Second War. David Sutherland (1923-2006) and Jacquelin Perry pioneered clinical applications in America and Jurg Baumann (1926-2000) in Europe. It was not until the advent of modern computers that clinical gait analysis became widely available.

A Third Note: Helmholtz, Palestrina, and the Early History of Musicology.

PubMed

Kursell, Julia

2015-06-01

This contribution focuses on Hermann von Helmholtz's work on Renaissance composer Giovanni Pierluigi da Palestrina. Helmholtz used his scientific concept of distortion to analyze this music and, reversely, to find corroboration for the concept in his musical analyses. In this, his work interlocked with nineteenth-century aesthetic and scholarly ideals. His eagerness to use the latest products of historical scholarship in early music reveals a specific view of music history. Historical documents of music provide the opportunity for the discovery of new experimental research topics and thereby also reveal insights into hearing under different conditions. The essay argues that this work occupies a peculiar position in the history of musicology; it falls under the header of "systematic musicology," which eventually emerged as a discipline of musicology at the end of the nineteenth century. That this discipline has a history at all is easily overlooked, as many of its contributors were scientists with an interest in music. A history of musicology therefore must consider at least the following two caveats: parts of it take place outside the institutionalized field of musicology, and any history of musicology must, in the last instance, be embedded in a history of music.

could be possible to infer the genesis of the scarps as due to complex tectono-karstic phenomena. As for case (ii), our ongoing analyses are aimed to analyze the tectonic "significance" of some closed depressions, up to 4 km long and to 0,5-1 km large, that occur along the south-western slope of the Gran Sasso Range. All these small depression are NW-SE trending. As already described by Bosi et al. (1989), Galadini and Giuliani (1993), D'Agostino et al. (1998), Falcucci et al. (2015), these closed depressions are bounded by scarps carved onto the carbonate bedrock and, subordinately, onto early Quaternary slope deposits, reaching height of up to 5 m. These scarps are preferentially NE dipping, even if in few cases some SW dipping scarp are also present . The field work has permitted to attest that these scarps are related to shear planes that that displaced two subsequent of Early Pleistocene breccias formations (the Valle Valiano Fm. and Fonte Vedice Fm.; Bosi e Bertini, 1993; D'agostino et al., 1997). A paleoseismological trench was also performed across one of these scarps, attesting the activity of these shear planes also in recent times, providing indications result about the deformation style.

The ability to use data stored in the current Earth Observing System (EOS) archives for studying regional or global phenomena is highly dependent on having a detailed understanding of the data's internal structure and physical implementation. Gaining this understanding and applying it to data reduction is a time- consuming task that must be undertaken before the core investigation can begin. This is an especially difficult challenge when science objectives require users to deal with large multi-sensor data sets that are usually of different formats, structures, and resolutions, for example, when preparing data for input into modeling systems. The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) has taken a major step towards meeting this challenge by developing an infrastructure with a Web interface that allows users to perform interactive analysis online without downloading any data, the GES-DISC Interactive Online Visualization and Analysis Infrastructure or "Giovanni." Giovanni provides interactive, online, analysis tools for data users to facilitate their research. There have been several instances of this interface created to serve TRMM users, Aerosol scientists, Ocean Color and Agriculture applications users. The first generation of these tools support gridded data only. The user selects geophysical parameters, area of interest, time period; and the system generates an output on screen in a matter of seconds. The currently available output options are: Area plot averaged or accumulated over any available data period for any rectangular area; Time plot time series averaged over any rectangular area; Time plots image view of any longitude-time and latitude-time cross sections; ASCII output for all plot types; Image animation for area plot. In the future, we will add correlation plots, GIS-compatible outputs, etc. This allow user to focus on data content (i.e. science parameters) and eliminate the need for expensive learning

Short History of Malaria and Its Eradication in Italy With Short Notes on the Fight Against the Infection in the Mediterranean Basin

Majori, Giancarlo

2012-01-01

In Italy at the end of 19th Century, malaria cases amounted to 2 million with 15,000–20,000 deaths per year. Malignant tertian malaria was present in Central-Southern areas and in the islands. Early in the 20th Century, the most important act of the Italian Parliament was the approval of laws regulating the production and free distribution of quinine and the promotion of measures aiming at the reduction of the larval breeding places of Anopheline vectors. The contribution from the Italian School of Malariology (Camillo Golgi, Ettore Marchiafava, Angelo Celli, Giovanni Battista Grassi, Amico Bignami, Giuseppe Bastianelli) to the discovery of the transmission’s mechanism of malaria was fundamental in fostering the initiatives of the Parliament of the Italian Kingdom. A program of cooperation for malaria control in Italy, supported by the Rockefeller Foundation started in 1924, with the establishment of the Experimental Station in Rome, transformed in 1934 into the National Institute of Public Health. Alberto Missiroli, Director of the Laboratory of Malariology, conducted laboratory and field research, that with the advent of DDT brought to Italy by the Allies at the end of the World War II, allowed him to plan a national campaign victorious against the secular scourge.

2010-05-01

The paper refers to the on going experience of the project "The Historic Atlas of Modern Rome" implemented by CROMA (Centro di ateneo per lo studio di Roma) - University Roma Tre. The project combines research in urban history with geographical information systems, and has as main objective to study the "historic environment" of Rome and its transformations. In 1748, Giovanni Battista Nolli (1692-1756) published his «New Map of Rome» (Nuova Pianta di Roma). This work represents the first geometrically correct representation of Rome within the city walls, and the only map deriving from a topographical survey of which the procedures are known. The map represents a precious source of information and a valid cartographic basis for the study of the successive phases of the city development. The presentation will illustrate the characteristics of this cartographic source, the results obtained from the georeferencing process and the construction of a GIS system for the city of Rome in the 18th century. The described methodology stands at the basis of the first volume of the Atlas, that will be shortly published in printable as well as in digital version, in a CD Rom containing a graphical interface that permits the interactive interrogation of map and databases.

Experiments and simulations of flux rope dynamics in a plasma

The behavior of flux ropes is a key issue in solar, space and astrophysics. For instance, magnetic fields and currents on the Sun are sheared and twisted as they store energy, experience an as yet unidentified instability, open into interplanetary space, eject the plasma trapped in them, and cause a flare. The Reconnection Scaling Experiment (RSX) provides a simple means to systematically characterize the linear and non-linear evolution of driven, dissipative, unstable plasma-current filaments. Topology evolves in three dimensions, supports multiple modes, and can bifurcate to quasi-helical equilibria. The ultimate saturation to a nonlinear force and energy balance is the link to a spectrum of relaxation processes. RSX has adjustable energy density β1 to β 1, non-negligible equilibrium plasma flows, driven steady-state scenarios, and adjustable line tying at boundaries. We will show magnetic structure of a kinking, rotating single line tied column, magnetic reconnection between two flux ropes, and pictures of three braided flux ropes. We use computed simulation movies to bridge the gap between the solar physics scales and experimental data with computational modeling.

We examine climatologies derived from eight years of temperature, water vapor, cloud, and trace gas observations made by the Atmospheric Infrared Sounder (AIRS) instrument flying on the Aqua satellite and compare them to similar climatologies constructed with data from a global assimilation model, the Modern Era Retrospective-Analysis for Research and Applications (MERRA). We use the AIRS climatologies to examine anomalies and trends in the AIRS data record. Since sampling can be an issue for infrared satellites in low earth orbit, we also use the MERRA data to examine the AIRS sampling biases. By sampling the MERRA data at the AIRS space-time locations both with and without the AIRS quality control we estimate the sampling bias of the AIRS climatology and the atmospheric conditions where AIRS has a lower sampling rate. While the AIRS temperature and water vapor sampling biases are small at low latitudes, they can be more than a few degrees in temperature or 10 percent in water vapor at higher latitudes. The largest sampling biases are over desert. The AIRS and MERRA data are available from the Goddard Earth Sciences Data and Information Services Center (GES DISC). The AIRS climatologies we used are available for analysis with the GIOVANNI data exploration tool. (see, http://disc.gsfc.nasa.gov).

Social and cultural factors had a critical role in determining the genetic structure of Europe. Therefore, socially stratified populations may help to focus on specific episodes of European demographic history. In this study, we use uniparental markers to analyse the genetic structure of Partecipanza in San Giovanni in Persiceto (Northern Italy), a peculiar institution whose origins date back to the Middle Ages and whose members form the patrilineal descent of a group of founder families. From a maternal point of view (mtDNA), Partecipanza is genetically homogeneous with the rest of the population. However, we observed a significant differentiation for Y-chromosomes. In addition, by comparing 17 Y-STR profiles with deep-rooted paternal pedigrees, we estimated a Y-STR mutation rate equal to 3.90 * 10−3 mutations per STR per generation and an average generation duration time of 33.38 years. When we used these values for tentative dating, we estimated 1300-600 years ago for the origins of the Partecipanza. These results, together with a peculiar Y-chromosomal composition and historical evidence, suggest that Germanic populations (Lombards in particular) settled in the area during the Migration Period (400–800 AD, approximately) and may have had an important role in the foundation of this community.

Astrology in court: The Spanish Inquisition, authority, and expertise.

Lanuza-Navarro, Tayra M C

2017-06-01

Astrology, its legitimacy, and the limits of its acceptable practice were debated in sixteenth- and seventeenth-century Europe. Many of the related arguments were mediated by the work of Giovanni Pico della Mirandola and the responses to it. Acknowledging the complexities of the relationship between astrological ideas and Christian teachings, this paper focuses on the Catholic debates by specifically considering the decisions about astrology taken by the Spanish Inquisition. The trials of astrologers are examined with the aim of understanding the role of experts in astrology in early modern Spain. This study brings into view the specific nature of the debate on astrology in Spain, the consequences of the actions of the Inquisition and the social control it exerted. The historical events discussed comprise a particular case and also mirror the general debates about astrology taking place in early modern Europe. The experts' opinions expressed in trials and in reports about the discipline received by the Inquisition reveal two key traits of the debate: the dispute about who had the authority to decide on the legitimacy of astrology and the disagreement about what constituted natural and judicial astrological practices. These led to different opinions about what was to be done with each defendant and about what content in their books ought to be forbidden.

The study was conducted to explore the knowledge of pregnant women about influenza, influenza vaccine during pregnancy and the attitudes regarding immunization. A questionnaire based on the model proposed by Yudin in 2009 was translated, adapted and administered to 309 pregnant women in the third trimester of pregnancy between October 1 and December 1, 2013 at San Giovanni Calibita Fatebenefratelli hospital of Rome (Italy). Most of the interviewed women (68.9%) answered that influenza is highly contagious, 34.6% of them believed that pregnant women have the same risk of complications as non-pregnant women. Only 5.8% were aware that the vaccine is recommended for women in the second and third trimester of pregnancy and only 14.2% of women answered that the vaccine is safe during pregnancy. Only 3/309 women reported recommendation and offer of vaccination during current pregnancy, but none of them was vaccinated. Overall, knowledge regarding influenza, implications during pregnancy and influenza vaccine was poor among pregnant women. In Italy, the National Vaccine Prevention Plan 2012-2014 recommends influenza vaccine during pregnancy, but only 18/309 were aware of this recommendation. These results suggest that in order to increase influenza vaccine acceptance it is necessary to improve pregnant women knowledge about influenza and to offer education to healthcare providers.

Improved atmospheric 3D BSDF model in earthlike exoplanet using ray-tracing based method

The studies on planetary radiative transfer computation have become important elements to disk-averaged spectral characterization of potential exoplanets. In this paper, we report an improved ray-tracing based atmospheric simulation model as a part of 3-D earth-like planet model with 3 principle sub-components i.e. land, sea and atmosphere. Any changes in ray paths and their characteristics such as radiative power and direction are computed as they experience reflection, refraction, transmission, absorption and scattering. Improved atmospheric BSDF algorithms uses Q.Liu's combined Rayleigh and aerosol Henrey-Greenstein scattering phase function. The input cloud-free atmosphere model consists of 48 layers with vertical absorption profiles and a scattering layer with their input characteristics using the GIOVANNI database. Total Solar Irradiance data are obtained from Solar Radiation and Climate Experiment (SORCE) mission. Using aerosol scattering computation, we first tested the atmospheric scattering effects with imaging simulation with HRIV, EPOXI. Then we examined the computational validity of atmospheric model with the measurements of global, direct and diffuse radiation taken from NREL(National Renewable Energy Laboratory)s pyranometers and pyrheliometers on a ground station for cases of single incident angle and for simultaneous multiple incident angles of the solar beam.

Around a camphoric-acid boat, is the surfactant adsorbed on to the interface or dissolved in the bulk?

A camphoric-acid boat (c-boat for short), a cylindrical gel tablet infused with camphoric acid, moves spontaneously when placed on an air-water interface. This system is a classic example of propulsion driven by Marangoni forces. Despite rich history on particles propelled by Marangoni forces, including contributions by figures such as Benjamin Franklin, Allesandro Volta, and Giovanni Venturi, the underlying fluid dynamics remains poorly understood. A key missing piece is the nature of the surfactant; in our case, the question is whether the camphoric acid is dissolved in the bulk or adsorbed on to the interface. We gain insight into this piece by holding the c-boat stationary and measuring the surrounding axisymmetric flow velocity to a precision needed to distinguish between the two possibilities. For soluble surfactants, it is known that the velocity field decays as r - 2 / 3, where r is the distance from the center of the c-boat. Whereas, for surfactant adsorbed on to the air-water interface, we derive that the surrounding velocity fields decays as r - 3 / 5. Based on our measurements we deduce that, even though soluble in water, the Marangoni flow results from a layer of camphoric acid adsorbed to the air-water interface.

Infuence of Averaging Method on the Evaluation of a Coastal Ocean Color Event on the U.S. Northeast Coast

2010-01-01

Application of appropriate spatial averaging techniques is crucial to correct evaluation of ocean color radiometric data, due to the common log-normal or mixed log-normal distribution of these data. Averaging method is particularly crucial for data acquired in coastal regions. The effect of averaging method was markedly demonstrated for a precipitation-driven event on the U.S. Northeast coast in October-November 2005, which resulted in export of high concentrations of riverine colored dissolved organic matter (CDOM) to New York and New Jersey coastal waters over a period of several days. Use of the arithmetic mean averaging method created an inaccurate representation of the magnitude of this event in SeaWiFS global mapped chl a data, causing it to be visualized as a very large chl a anomaly. The apparent chl a anomaly was enhanced by the known incomplete discrimination of CDOM and phytoplankton chlorophyll in SeaWiFS data; other data sources enable an improved characterization. Analysis using the geometric mean averaging method did not indicate this event to be statistically anomalous. Our results predicate the necessity of providing the geometric mean averaging method for ocean color radiometric data in the Goddard Earth Sciences DISC Interactive Online Visualization ANd aNalysis Infrastructure (Giovanni).

The following paper by Professor GiovanniNeri and colleagues was originally published in 1988, American Journal of Medical Genetics 30:287–299. This paper represented a seminal work at the time of publication as it not only reported a new family with a disorder that had been called the “gigantism-dysplasia syndrome”, but also suggested naming the condition the Simpson-Golabi-Behmel syndrome. This eponym has clearly stood “the test of time”, and that designation is now widely accepted. This paper is graciously republished by Wiley-Blackwell in the Special Festschrift issue honoring Professor Neri. We report on another family with the so-called "gigantism-dysplasia syndrome", an X-linked condition characterized by pre-and postnatal overgrowth, characteristic face with apparent coarseness, dysplastic changes in several tissues, and mild intellectual impairment. This condition has been called the Golabi-Rosen syndrome; however, we agree that is the same entity as that described, in a milder form, by Simpson et al. in 1975 and by Behmel et al. in 1984. Therefore, we suggest that this entity be designated the Simpson-Golabi-Behmel syndrome. The manifestations in affected individuals suggest that this condition represents an X-linked encephalo-tropho-schisis syndrome. © 2013 Wiley Periodicals, Inc.

Abraham's discovery of the 'bad mother'. A contribution to the history of the theory of depression.

PubMed

May, U

2001-04-01

The author shows how, after Freud struggled in vain from the 1890s to develop a theory of depression, Abraham succeeded for the first time in finding an approach to the understanding of depression a few years before the publication of Freud's 'Mourning and melancholia'. It is contained in his study of the painter Giovanni Segantini (1911), which also includes a description, imbued with a new atmospheric quality, of the mother-son relationship that centres on the concept of the 'bad mother'. The author points out that Abraham's 'good/bad' dimension is effectively absent from Freud's published work up to 1911 and is also at variance with his view of the relationship between son and mother. In later contributions, too, Abraham maintained that unconscious hate directed at the mother, who is experienced as 'bad' but longed for as 'good', was a central factor in the aetiology of depression, a view he had to defend vis-à-vis Freud. The author contends that in the Segantini paper Abraham was describing an inner world similar to that evinced by the work of Melanie Klein and significantly different from Freud's. It is characterised by hate, revenge, death wishes and guilt feelings on the one hand and tranquillity and inner peace on the other.

Nicolaus Steno's new myology (1667): rather than muscle, the motorfibre should be called animal's organ of movement.

PubMed

Kardel, Troels

2008-01-01

Muscular movement is the result of fibre shortening. How did this basic insight arise? Based on several of his observations, Nicolaus Steno in 1664 and 1667 proposed that muscles shorten when fibres shorten, and that skeletal muscles consist of uniform motor fibres layered as pennate structures. The basis for a new myology was provided in a geometrical model of the movement of the muscles. But fibre shortening was incompatible with the dominant ancient theory of contraction by inflation that was favoured by Descartes and by Steno's contemporaries William Croone, Thomas Willis, John Mayow, and Giovanni Borelli due to their adherence to the Aristotelian axiom: "Anything which moves is moved by something else". The inflation theory blindfolded researchers well into the eighteenth century for skeletal and heart muscles. When the shortening of motor fibres was eventually visualised by microscopy, this inflation theory was no longer tenable. Steno's structural claim on skeletal muscles was also rejected by Borelli and by later commentators. Pennate muscles were only rarely displayed until 1981 when macro-anatomical studies showed the morphology of most skeletal muscles to be similar to that described by Steno. Steno's proposals on muscles have since become a common-place in computer models applied in the study of human and animal motion.

Reusable Social Networking Capabilities for an Earth Science Collaboratory

A vast untapped resource of data, tools, information and knowledge lies within the Earth science community. This is due to the fact that it is difficult to share the full spectrum of these entities, particularly their full context. As a result, most knowledge exchange is through person-to-person contact at meetings, email and journal articles, each of which can support only a limited level of detail. We propose the creation of an Earth Science Collaboratory (ESC): a framework that would enable sharing of data, tools, workflows, results and the contextual knowledge about these information entities. The Drupal platform is well positioned to provide the key social networking capabilities to the ESC. As a proof of concept of a rich collaboration mechanism, we have developed a Drupal-based mechanism for graphically annotating and commenting on results images from analysis workflows in the online Giovanni analysis system for remote sensing data. The annotations can be tagged and shared with others in the community. These capabilities are further supplemented by a Research Notebook capability reused from another online analysis system named Talkoot. The goal is a reusable set of modules that can integrate with variety of other applications either within Drupal web frameworks or at a machine level.

SUMMARY Free flap surgery is overall considered the gold standard in head and neck reconstruction, with a success rate of 95%. The management of a total flap necrosis and which solution, between a pedicled or a second free flap, is safer for a salvage procedure is still controversial. Object of this study is to describe the authors' management of total free flap loss in head and neck reconstruction and compare the choices and results to those reported in the literature. From January 2012 to January 2016, 149 consecutive free flaps were performed at the Maxillo- Facial Operative Unit of the Hospital Casa Sollievo della Sofferenza in San Giovanni Rotondo (Italy) for reconstruction of head and neck defects. Of these, 6 flaps were lost due to a total necrosis. In 5 cases it was decided to harvest a second free flap, and in the remaining patient a temporalis muscle flap was used. All the free salvage flaps were successful, without complications and with a good aesthetic and functional recovery. Analysing the data obtained, and comparing them with those reported in the literature, it can be concluded that a second subsequent free flap can be considered an ideal and safe procedure in salvage surgery.

Global mapping of stratigraphy of an old-master painting using sparsity-based terahertz reflectometry.

The process by which art paintings are produced typically involves the successive applications of preparatory and paint layers to a canvas or other support; however, there is an absence of nondestructive modalities to provide a global mapping of the stratigraphy, information that is crucial for evaluation of its authenticity and attribution, for insights into historical or artist-specific techniques, as well as for conservation. We demonstrate sparsity-based terahertz reflectometry can be applied to extract a detailed 3D mapping of the layer structure of the 17th century easel painting Madonna in Preghiera by the workshop of Giovanni Battista Salvi da Sassoferrato, in which the structure of the canvas support, the ground, imprimatura, underpainting, pictorial, and varnish layers are identified quantitatively. In addition, a hitherto unidentified restoration of the varnish has been found. Our approach unlocks the full promise of terahertz reflectometry to provide a global and detailed account of an easel painting's stratigraphy by exploiting the sparse deconvolution, without which terahertz reflectometry in the past has only provided a meager tool for the characterization of paintings with paint-layer thicknesses smaller than 50 μm. The proposed modality can also be employed across a broad range of applications in nondestructive testing and biomedical imaging.

In 1674 Thomas Willis reported that the presence of urine 'as sweet as honey' was the pathognomonic sign of diabetes mellitus. In the 19th Century several reactions for the detection of glucose in urine were proposed and glucose measurement became common in the laboratories that were being set up in Europe. A case of diabetes mellitus, diagnosed by Namias, the head of the Women's Section of the Medicine Department of Venice Hospital, was reported in 1863 in the 'Giornale Veneto di Scienze Mediche' which contains clinical and laboratory information. A 34-year-old woman was admitted to the hospital for polydypsia, polyuria, bulimia and fatigue. Urine was weighed for 2 months (2-10 kgday(-1)) and the relative density ranged from 1.045 to 1.038. Glucose was measured in the urine using Moore, Trommer and Fehling reagents. A few days after admission a urine sample showed 7.69 parts/100 parts of urine and a blood sample showed 547 mg of glucose/100 g of serum. The assays were carried out in the Clinical Laboratory of Venice Hospital, founded in 1863, directed by Giovanni Bizio, one of the first chemists who graduated at Padua University. In 1863 chemical analyses were commonly carried out in Venice as in the other parts of Habsburg empire.

In this contribution, the results of some integrated geophysical prospecting (magnetometric and GPR) are exposed. This work has been performed in collaboration between archaeologists and geophysicists within the research project "History and Global Archaeology of the Rural Landascapes in Italy, between Late Antiquity and Medieval period. Integrated systems of sources, methodologies, and technologies for a sustainable development", financed by the Italian Ministry for Instruction, University and Research MIUR. In particular, the archaeological sites of Badia and San Giovanni in Malcantone, both in the Apulia Region (eastern-southern Italy) have been prospect. The sites have been identified on the basis of available documents, archaeological surveys and testimonies. In particular, we know that in Badia [1] it was probable the presence of an ancient roman villa of the late ancient period (strongly damaged by the subsequent ploughing activities). Whereas in San Giovanni there is still, today, a small chapel (deconsecrated) that was likely to be part of a previous larger church (probably a basilica of the early Christian period) restricted in the subsequent centuries (probably in more phases). The Saracen raids of the XVI centuries made the site ruined and abandoned. In both sites integrated prospecting have been performed [2-6] with a the integration of archaeological, magnetometer and a GPR data have provided some interesting results, allowing to overcome the difficulties relative to an extensive GPR prospecting, that could not be performed because of the intrinsic superficial roughness and/or the intensive ploughing activities. The prospecting activities, in particular, have added elements that seem to confirm the main archaeological hypothesis that motivate their performing, as it will be show at the conference.

There is confusion about the first description of the association between crush syndrome and renal failure. It has been traditionally attributed to Bywaters and Beall. The present study aims to analyze the problem by analyzing medical reports on the Messina-Reggio Calabria earth-quake of December 28, 1908 by using documents heretofore unknown. It demonstrates that first description of rabdomyolysis with renal failure is attributed to Antonino DAntona (1842- 1913). DAntona, professor of surgery at the University of Naples, coordinated the health net organized in Naples to assist persons wounded during the quake. Many of them in shock were transferred to Naples by ships. Franz von Colmers (1875-1960) was the chief surgeon of the German Mission of the Red Cross after the quake. Because his late arrival, he did not treat patients with shock. He described rabdomyolysis. The third medical report is that of Rocco Caminiti (1868-1946), collaborator of DAntona at the University of Naples, and chief of surgery at the Loreto Hospital. He directed a rescue group in Villa San Giovanni and Reggio Calabria. In 1910, he reported on rabdomyolysis in patients treated in the place of the disaster. Therefore the present study indicates that Antonino DAntona holds the priority for description of rabdomyolysis and kidney injury. There is no longer a place for the eponym Bywaters syndrome.

Optimal Reorganization of NASA Earth Science Data for Enhanced Accessibility and Usability for the Hydrology Community

A long-standing "Digital Divide" in data representation exists between the preferred way of data access by the hydrology community and the common way of data archival by earth science data centers. Typically, in hydrology, earth surface features are expressed as discrete spatial objects (e.g., watersheds), and time-varying data are contained in associated time series. Data in earth science archives, although stored as discrete values (of satellite swath pixels or geographical grids), represent continuous spatial fields, one file per time step. This Divide has been an obstacle, specifically, between the Consortium of Universities for the Advancement of Hydrologic Science, Inc. and NASA earth science data systems. In essence, the way data are archived is conceptually orthogonal to the desired method of access. Our recent work has shown an optimal method of bridging the Divide, by enabling operational access to long-time series (e.g., 36 years of hourly data) of selected NASA datasets. These time series, which we have termed "data rods," are pre-generated or generated on-the-fly. This optimal solution was arrived at after extensive investigations of various approaches, including one based on "data curtains." The on-the-fly generation of data rods uses "data cubes," NASA Giovanni, and parallel processing. The optimal reorganization of NASA earth science data has significantly enhanced the access to and use of the data for the hydrology user community.

Land surface temperature (Ts) is an important element to measure the state of terrestrial ecosystems and to study surface energy budgets. In support of the land cover/land use change-related international program MAIRS (Monsoon Asia Integrated Regional Study), we have collected global monthly Ts measured by MODIS since the beginning of the missions. The MODIS Ts time series have approximately 11 years of data from Terra since 2000 and approximately 9 years of data from Aqua since 2002, which makes possible to study the recent climate, such as trend. In this study, monthly climatology from two platforms are calculated and compared with that from AIRS. The spatial patterns of Ts trends are accessed, focusing on the Eurasia region. Furthermore, MODIS Ts trends are compared with those from AIRS and NASA's atmospheric assimilation model, MERRA (Modern Era Retrospective-analysis for Research and Applications). The preliminary results indicate that the recent 8-year Ts trend shows an oscillation-type spatial variation over Eurasia. The pattern is consistent for data from MODIS, AIRS, and MERRA, with the positive center over Eastern Europe, and the negative center over Central Siberia. The calculated climatology and anomaly of MODIS Ts will be integrated into the online visualization system, Giovanni, at NASA GES DISC for easy use by scientists and general public.

Detailed analysis of satellite data for the period 2002-2016 provides an understanding of the land-sea interaction and its association with the vegetation conditions over the Indian continent. The Indian Ocean dipole (IOD) phenomenon is also considered to understand the atmospheric dynamics and meteorological parameters. GPS water vapor and meteorological parameters (relative humidity and water vapor) from the Indian Institute of Science (IISC) Bangalore have been considered for meteorological data for the period 2008-2016. Atmospheric parameters (water vapor, precipitation rate, land temperature, total ozone column) have been considered using through NASA Giovanni portal and GPS water vapor through SoumiNet data to study relation between Sea Surface temperature (SST) from Indian Ocean, Bay of Bengal and Arabian Sea. Our detailed analysis shows that SST has strong impact on the NDVI at different locations, the maximum impact of SST is observed at lower latitudes. The NDVI over the central and northern India (Indo-Gangetic plains (IGP) is not affected. The SST and NDVI shows high correlation in the central and northern parts, whereas the correlation is poor in the southern parts i.e. close to the ocean. The detailed analysis of NDVI data provides progression of the drought conditions especially in the southern parts of India and also shows impact of the El Nino during 2015-2016.

European team gauges a gamma-ray star

Italian astrophysicists have pushed the Hubble Space Telescope to the limit of its powers in finding the distance of Geminga, a pointlike object 500 light-years from the Earth. It is the prototype of a novel kind of star, a radio-silent neutron star, which may be much more common in the Universe than previously supposed. Geminga is so weak in visible light that Hubble had to stare at the spot for more than an hour to register it adequately. The object is nevertheless one of the brightest sources of gamma-rays in the sky, and its output of this very energetic form of radiation can now be accurately ganged. Neutron stars, first discovered as radio pulsars in 1967, are fantastic creations of exploding stars, just one step short of a black hole. They are heavier than the Sun yet only about twenty kilometres wide. Made of compressed nuclear matter, they have gravity and magnetic fields many billions of times stronger than on the Earth. With the first direct measurement of the distance of a radio-silent neutron star, astrophysicists can assess Geminga's power and speed of motion. The astronomical task was like judging the width of a one- franc piece in Paris, seen from the distance of Sicily. Geminga's low brightness greatly aggravated the difficulties. Patrizia Caraveo and her colleagues at the Istituto di Fisica Cosmica in Milan arranged for Hubble's wide-field camera (WFPC2) to make its prolonged observations of Geminga three times. Their findings will be published in Astrophysical Journal Letters on 20 April 1996. Caraveo's co-authors are Giovanni Bignami and Roberto Mignani of Milan, and Laurence Taff of Johns Hopkins University, Maryland. The Italians took advantage of the European Space Agency's collaboration with NASA in the Hubble mission, which gives European astronomers privileged access to the Space Telescope. Shifts of millionths of a degree The three sightings of Geminga, made at intervals of six months, revealed small shifts in the position of the faint

Specifically, the GES DISC worked closely with the University of Texas (also part of the NASA ACCESS project) to seamlessly integrate these hydrology-related variables into CUAHSI-HIS. With NLDAS, GLDAS, and MERRA data integrated into CUAHSI-HIS, the data can be accessed via HydroDesktop (a windows-based GIS application) along with other existing HIS data, and analyzed with the built-in functions for water-cycle-related applications, research, and data validation. Case studies will be presented on the access to and use of NLDAS, GLDAS, and MERRA data for drought monitoring, Probable Maximum Precipitation (PMP), hurricane rainfall effects on soil moisture and runoff, as well as data inter-comparison. An example of GLDAS in ArcGIS Online, World Soil Moisture, will also be given. Featured with the long time series of GLDAS soil moisture data and powered by Esri-ArcGIS, the World Soil Moisture server allows users to click on any location in the world to view its soil moisture in ASCII or as a time series plot.

The 6(th) archaeological excavation campaign performed at the 'Pieve di Pava' (San Giovanni d'Asso, Siena, Italy) unearthed a privileged stone burial of a single individual (US 2378), covered by a monolithic slab and placed in front of an altar. The skeletal remains of a young male (18-20 years old), not in anatomical connection, were found at the bottom floor of a tomb (160 cm long, 40 cm large and over 70 cm deep). A multidisciplinary study has been carried out concerning that privileged bone burial. The study combines paleopathology studies, stable isotope palaeodietary reconstruction, radiocarbon dating and archaeological analyses. (14)  C dating of the skeleton revealed a date between 650 and 688 AD. Stable isotope analysis (δ(18) O, δ(13) C, δ(15) N) attested that he was probably a member of the local population, whose diet was rather rich in animal proteins. The paleopathological study diagnosed a case of acromesomelic dysplasia, a congenital anomaly with disproportion of the limbs. Archaeological evidence regarding the circular delimitation of the bones suggested that the skeleton was a secondary deposition, transported to the church in a sack. We argue that the relic was used for the re-consecration of the church, following the restoration work in the 8(th) century. We conclude that the skeleton belonged to an eminent personage (e.g., either the member of a local elite family or a saint). Copyright © 2012 John Wiley & Sons, Ltd.

Using Selection Pressure as an Asset to Develop Reusable, Adaptable Software Systems

2007-12-01

The Goddard Earth Sciences Data and Information Services Center (GES DISC) at NASA has over the years developed and honed a number of reusable architectural components for supporting large-scale data centers with a large customer base. These include a processing system (S4PM) and an archive system (S4PA) based upon a workflow engine called the Simple, Scalable, Script-based Science Processor (S4P); an online data visualization and analysis system (Giovanni); and the radically simple and fast data search tool, Mirador. These subsystems are currently reused internally in a variety of combinations to implement customized data management on behalf of instrument science teams and other science investigators. Some of these subsystems (S4P and S4PM) have also been reused by other data centers for operational science processing. Our experience has been that development and utilization of robust, interoperable, and reusable software systems can actually flourish in environments defined by heterogeneous commodity hardware systems, the emphasis on value-added customer service, and continual cost reduction pressures. The repeated internal reuse that is fostered by such an environment encourages and even forces changes to the software that make it more reusable and adaptable. Allowing and even encouraging such selective pressures to software development has been a key factor in the success of S4P and S4PM, which are now available to the open source community under the NASA Open Source Agreement.

The presentation describes the recently awarded ACCESS project to provide data management of NASA remote sensing data for the Northern Eurasia Earth Science Partnership Initiative (NEESPI). The project targets integration of remote sensing data from MODIS, and other NASA instruments on board US-satellites (with potential expansion to data from non-US satellites), customized data products from climatology data sets (e.g., ISCCP, ISLSCP) and model data (e.g., NCEP/NCAR) into a single, well-architected data management system. It will utilize two existing components developed by the Goddard Earth Sciences Data & Information Services Center (GES DISC) at the NASA Goddard Space Flight Center: (1) online archiving and distribution system, that allows collection, processing and ingest of data from various sources into the online archive, and (2) user-friendly intelligent web-based online visualization and analysis system, also known as Giovanni. The former includes various kinds of data preparation for seamless interoperability between measurements by different instruments. The latter provides convenient access to various geophysical parameters measured in the Northern Eurasia region without any need to learn complicated remote sensing data formats, or retrieve and process large volumes of NASA data. Initial implementation of this data management system will concentrate on atmospheric data and surface data aggregated to coarse resolution to support collaborative environment and climate change studies and modeling, while at later stages, data from NASA and non-NASA satellites at higher resolution will be integrated into the system.

Carnevale, F

2012-01-01

The author proposes a reading of "Concerning incombustible flax or asbestos stone" which was published in 1696 by Giovanni Giustino Ciampini, who was a historian, a man of the church and scientist in Rome. The text, which was originally written in Latin, is an excellent and early description of the need felt by the majority of scientists in Europe at that time for a change in method: that is, to use scientific experiments to explain and control the natural phenomena observed and even perhaps mythologized right from antiquity. In the case of asbestos this was necessary to check the veracity and consistency of a series of recommendations handed down by the earliest authors but also to revive and reinvent the techniques that had largely been lost so as to be able to utilize and develop a substance that it was thought could be of great benefit to society. In the presentation of Ciampini's text an attempt is made to recall and contextualize the earliest knowledge on asbestos and follow its evolution over a long historical period, up to the first half of the nineteenth century. It can thus be seen how asbestos, once considered "a wonder of nature", became a raw material widely used in industrial applications. The most significant steps in this phase of transformation were taken thanks to Italian entrepreneurs and technicians and to the presence of asbestos in the Alpine valleys of Italy.

The opportunity of the 2016 transit of Mercury for measuring the solar diameter

The transit of Mercury occurred two times in this century: 2003, May 7 and 2006, November 8. In 2016 there is another opportunity to observe this phenomenon and measure the solar diameter with the method of comparing the ephemerides with the observations. This method has been presented by I. I. Shapiro in 1980, the data of the observed transits (since 1631) have been re-analyzed by Sveshnikov (2002) and an improvement on the observed data, to avoid the confusion given by the black-drop effect, has been presented by C. Sigismondi and collaborators since 2005 by exploiting the idea of measuring the chord drawn by the solar limb with the disk of the transiting planet presented by G. Di Giovanni (2005) on the transit of Venus: the improvement is obtained by extrapolating to zero the analytic chord fitting the observations without the black drop, but in the ingress/egress phases. For the transit of 2006 K. Reardon with IBIS (California) and J. Pasachoff with Mauna Kea (Hawaij) telescopes were ready to get useful data but the weather's conditions were not good, and only the SOHO data (M. Emilio, 2012) contributed to the solar diameter monitoring. A network of European observers (IOTA/ES) and observatories (coronograph of Bialkow, PL 56 cm; IRSOL, Locarno CH - 45 cm Gregorian telescope; carte du ciel, Paris, FR 30 cm, Torre Solare di Monte Mario, Rome 26 cm) are active for the 2016 transit.

Anatomical models and wax Venuses: art masterpieces or scientific craft works?

PubMed Central

Ballestriero, R

2010-01-01

The art of wax modelling has an ancient origin but rose to prominence in 14th century Italy with the cult of votive artefacts. With the advent of Neoclassicism this art, now deemed repulsive, continued to survive in a scientific environment, where it flourished in the study of normal and pathological anatomy, obstetrics, zoology and botany. The achievement of having originated the creation of anatomical models in coloured wax must be ascribed to a joint effort undertaken by the Sicilian wax modeller Gaetano Giulio Zumbo and the French surgeon Guillaume Desnoues in the late 17th century. Interest in anatomical wax models spread throughout Europe during the 18th century, first in Bologna with Ercole Lelli, Giovanni Manzolini and Anna Morandi, and then in Florence with Felice Fontana and Clemente Susini. In England, the art of anatomical ceroplastics was brought to London from Florence by the sculptor Joseph Towne. Throughout the centuries many anatomical artists preferred this material due to the remarkable mimetic likeness obtained, far surpassing any other material. Independent of the material used, whether wood, wax or clay, anatomical models were always considered merely craft works confined to hospitals or faculties of medicine and have survived to this day only because of their scientific interest. Italian and English waxes are stylistically different but the remarkable results obtained by Susini and Towne, and the fact that some contemporary artists are again representing anatomical wax bodies in their works, makes the border that formerly separated art and craft indistinguishable.

Since the early 1960s, human neuropsychology, the study of brain-behavior interrelations, mainly based on the analysis of their pathological variations, brought about by brain damage, has had a remarkable systematical development in Italy. All this started in Milan, with the neurologist Ennio de Renzi, and his collaborators (Luigi Vignolo, then Anna Basso, Pietro Faglioni, Hans Spinnler, François Boller, and, more autonomously, Edoardo Bisiach), in the Clinic of Nervous and Mental Diseases. Scientists of the "Milan group" investigated several neuropsychological deficits caused by focal hemispheric lesions in large series of left- and right-brain-damaged patients, and control participants, comparable for cultural and demographic variables. Standardized tests and advanced statistical methods were used, which also applied to the diagnosis and rehabilitation of aphasia. Subsequently, neuropsychology developed in Italy extensively, reaching high international reputation. Leading neuropsychologists have been the neurologists Guido Gainotti (Rome), and Franco Denes (Padua), the physicians and psychologists Luigi Pizzamiglio (Rome), and Carlo Umiltà (Parma, with fruitful interactions with the neurophysiologists Giovanni Berlucchi, Giacomo Rizzolatti, and Carlo Marzi, from the school of Giuseppe Moruzzi in Pisa) A second scientific generation of neuropsychologists has then developed in the 1970s, trained by the abovementioned scientists, further boosting and spreading high-level basic and applied research (diagnosis and rehabilitation of neuropsychological deficits of patients with brain damage or dysfunction throughout the life span, from childhood to the elderly). Available techniques include structural and functional imaging (CT, PET, SPET, MRI and fMRI Scans, DTI), electrophysiological recording (EEG, ERPs), non-invasive brain stimulation (TMS, tES), and their combined use.

Studies have indicated that land cover and use changes in Northern Eurasia influence global climate system. However, the procedures are not fully understood and it is challenging to understand the interactions between the land changes in this region and the global climate. Having integrated data collections form multiple disciplines are important for studies of climate and environmental changes. Remote sensed and model data are particularly important die to sparse in situ measurements in many Eurasia regions especially in Siberia. The NASA GES DISC (Goddard Earth Sciences Data and Information Services Center) NEESPI data portal has generated infrastructure to provide satellite remote sensing and numerical model data for atmospheric, land surface, and cryosphere. Data searching, subsetting, and downloading functions are available. ONe useful tool is the Web-based online data analysis and visualization system, Giovanni (Goddard Interactive Online Visualization ANd aNalysis Infrastructure), which allows scientists to assess easily the state and dynamics of terrestrial ecosystems in Northern Eurasia and their interactions with global climate system. Recently, we have created a metadata database prototype to expand the NASA NEESPI data portal for providing a venue for NEESPI scientists fo find the desired data easily and leveraging data sharing within NEESPI projects. The database provides product level information. The desired data can be found through navigation and free text search and narrowed down by filtering with a number of constraints. In addition, we have developed a Web Map Service (WMS) prototype to allow access data and images from difference data resources.

The aim of this study was to assess the prognostic value of multifocality and the effectiveness of two different therapeutic strategies in patients with newly diagnosed hepatoblastoma. Between 1998 and 2011, 31 patients diagnosed with hepatoblastoma were referred to Ospedale Papa Giovanni XXIII, Bergamo, Italy. Patients were stratified according to SIOPEL protocols into high-risk (HR if AFP <100 ng/mL and/or PRETEXT IV and/or vascular invasion and/or extra-hepatic intra-abdominal disease and/or metastases) and standard-risk (SR, all others). The patient data we evaluated were: multifocality; patient age; gender; platelet count; AFP level at diagnosis, during treatment and follow-up; histotype; gestational age; birth weight; surgery (either resection or transplantation) and chemotherapy regimen adopted before and after surgery. The outcome measures were event free survival (EFS) and overall survival (OS); survival curves were estimated according to Kaplan-Meier. EFS and OS were associated significantly with multifocality (3-year EFS 40% vs. 95%, P = 0.006; 3-year OS 42% vs. 95%, P = 0.004). Multivariate analysis demonstrated that multifocality predicts lower EFS (hazard ratio 10.01, P = 0.007). Other factors at diagnosis did not reach statistical significance. A marked treatment dependent improvement was associated with intensive chemotherapy given both before and after liver transplantation (P = 0.06). Patients diagnosed with multifocal tumors had lower EFS levels. Multifocality should be taken into account for future stratification and further studied to assess genetic profile, immunochemistry and prognostic role. © 2014 Wiley Periodicals, Inc.

The Daniell cell, Ohm's law, and the emergence of the International System of Units

2014-01-01

Telegraphy originated in the 1830s and 40 s and flourished in the following decades but with a patchwork of electrical standards. Electromotive force was for the most part measured in units of the predominant Daniell cell, but each telegraphy company had their own resistance standard. In 1862, the British Association for the Advancement of Science formed a committee to address this situation. By 1873, they had given definition to the electromagnetic system of units (emu) and defined the practical units of the ohm as 109 emu units of resistance and the volt as 108 emu units of electromotive force. These recommendations were ratified and expanded upon in a series of international congresses held between 1881 and 1904. A proposal by Giovanni Giorgi in 1901 took advantage of a coincidence between the conversion of the units of energy in the emu system (the erg) and in the practical system (the Joule). As it was, the same conversion factor existed between the cgs based emu system and a theretofore undefined MKS system. By introducing another unit X (where X could be any of the practical electrical units), Giorgi demonstrated that a self-consistent MKSX system was tenable without the need for multiplying factors. Ultimately, the ampere was selected as the fourth unit. It took nearly 60 years, but in 1960, Giorgi's proposal was incorporated as the core of the newly inaugurated International System of Units (SI). This article surveys the physics, physicists, and events that contributed to those developments.

The Global Land Data Assimilation System (GLDAS) has been generating a series of land surface state (e.g., soil moisture and surface temperature) and flux (e.g., evaporation and sensible heat flux) products, simulated by four land surface models (CLM, Mosaic, Noah and VIC). These products are now accessible at the Hydrology Data and Information Services Center (HDISC), a component of the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC). Current GLDAS data hosted at HDISC include a set of 1.0° data products, covering 1979 to the present, from the four models and a 0.25° data product, covering 2000 to the present, from the Noah model. In addition to the basic anonymous ftp data downloading, users can avail themselves of several advanced data search and downloading services, such as Mirador and OPeNDAP. Mirador is a Google-based search tool that provides keywords searching, on-the-fly spatial and parameter subsetting of selected data. OPeNDAP (Open-source Project for a Network Data Access Protocol) enables remote OPeNDAP clients to access OPeNDAP served data regardless of local storage format. Additional data services to be available in the near future from HDISC include (1) on-the-fly converter of GLDAS to NetCDF and binary data formats; (2) temporal aggregation of GLDAS files; and (3) Giovanni, an online visualization and analysis tool that provides a simple way to visualize, analyze, and access vast amounts of data without having to download the data.

Supporting Coral Reef Ecosystem Management Decisions Appropriate to Climate Change

There has been a perception that the myriad of environmental information products derived from satellite and other instrumental sources means ipso facto that there is a direct use for them by environmental managers. Trouble is, as information providers, for the most part we don't really know what decisions managers face daily, nor is it a trivial matter to ascertain the effect of management decisions on the environment, at least in a time frame that facilitates timely maintenance and enhancement of decision support software. To bridge this gap in understanding, we conducted a Needs Assessment (using methodology from the NOAA/Coastal Services Center's Product Design and Evaluation training program) from December, 2011 through May, 2012, in which we queried 15 resource managers in southeast Florida to identify the types of climate data and information products they needed to understand the effects of climate change in their region of purview, and how best these products should be delivered and subsequently enhanced or corrected. Our intent has been to develop a suite of software and information products customized specifically for environmental managers. This report summarizes our success to date, including a report on the development of software for gathering and presenting specific types of climate data, and a narrative about how some U.S. government sponsored efforts, such as Giovanni and TerraVis, as well as non-governmental sponsored efforts such as Marxan, Zonation, SimCLIM, and other off-the-shelf software might be customized for use in specific regions.

The basophil activation test (BAT), has been proposed as a possible assay for the diagnosis of immediate-type allergy to beta-lactams (BLs). The aim of this study was to assess the utility of BAT in the diagnosis of amoxicillin (AMX) or AMX-clavulanate (AMX-C) IgE-mediated hypersensitivity in children and adults. Eighteen children and 21 adults, with clinical history of immediate reactions to AMX or AMX-C, were referred to Anna Meyer Children's Hospital and San Giovanni di Dio Hospital, respectively. They underwent in vivo tests (skin prick test and intradermal test). Moreover, BAT with AMX or AMX-C was performed within 6 months from the reaction. In the pediatric group, the concordance between the skin tests (ST) and BAT results was 83.3%. Upon comparing the symptom grades and ST results to the BAT results, we found that the reaction severity and ST positivity did not correlate with BAT results in children. In the adult group, the concordance between the ST and BAT results was 61.9%. Upon comparing patients with severe reactions and patients with mild reactions in terms of BAT results, we found a BAT sensitivity of 38.5% and a specificity of 100%. When comparing the symptom grades to the BAT results, we found that no patients with mild symptoms had a positive BAT result, whereas 38.5% of patients with severe symptoms had a positive BAT result. BAT does not seem to be a useful tool to increase the sensitivity of an allergy work-up to diagnose immediate hypersensitivity to AMX or AMX-C.

A major need stated by the NASA Earth science research strategy is to develop long-term, consistent, and calibrated data and products that are valid across multiple missions and satellite sensors. (NASA Solicitation for Making Earth System data records for Use in Research Environments (MEaSUREs) 2006-2010) Selected projects create long term records of a given parameter, called Earth Science Data Records (ESDRs), based on mature algorithms that bring together continuous multi-sensor data. ESDRs, associated algorithms, vetted by the appropriate community, are archived at a NASA affiliated data center for archive, stewardship, and distribution. See http://measures-projects.gsfc.nasa.gov/ for more details. This presentation describes the NASA GSFC Earth Science Data and Information Services Center (GES DISC) approach to managing the MEaSUREs ESDR datasets assigned to GES DISC. (Energy/water cycle related and atmospheric composition ESDRs) GES DISC will utilize its experience to integrate existing and proven reusable data management components to accommodate the new ESDRs. Components include a data archive system (S4PA), a data discovery and access system (Mirador), and various web services for data access. In addition, if determined to be useful to the user community, the Giovanni data exploration tool will be made available to ESDRs. The GES DISC data integration methodology to be used for the MEaSUREs datasets is presented. The goals of this presentation are to share an approach to ESDR integration, and initiate discussions amongst the data centers, data managers and data providers for the purpose of gaining efficiencies in data management for MEaSUREs projects.

Data Access Services that Make Remote Sensing Data Easier to Use

NASA Technical Reports Server (NTRS)

Lynnes, Christopher

2010-01-01

This slide presentation reviews some of the processes that NASA uses to make the remote sensing data easy to use over the World Wide Web. This work involves much research into data formats, geolocation structures and quality indicators, often to be followed by coding a preprocessing program. Only then are the data usable within the analysis tool of choice. The Goddard Earth Sciences Data and Information Services Center is deploying a variety of data access services that are designed to dramatically shorten the time consumed in the data preparation step. On-the-fly conversion to the standard network Common Data Form (netCDF) format with Climate-Forecast (CF) conventions imposes a standard coordinate system framework that makes data instantly readable through several tools, such as the Integrated Data Viewer, Gridded Analysis and Display System, Panoply and Ferret. A similar benefit is achieved by serving data through the Open Source Project for a Network Data Access Protocol (OPeNDAP), which also provides subsetting. The Data Quality Screening Service goes a step further in filtering out data points based on quality control flags, based on science team recommendations or user-specified criteria. Further still is the Giovanni online analysis system which goes beyond handling formatting and quality to provide visualization and basic statistics of the data. This general approach of automating the preparation steps has the important added benefit of enabling use of the data by non-human users (i.e., computer programs), which often make sub-optimal use of the available data due to the need to hard-code data preparation on the client side.

The long journey: a brief review of the eradication of rinderpest.

2012-12-01

In 2011, the 79th General Session of the World Assembly of the World Organisation for Animal Health (OIE) and the 37th Food and Agriculture Organization of the United Nations (FAD) Conference adopted a resolution declaring the world free from rinderpest and recommending follow-up measures to preserve the benefits of this new and hard-won situation. Eradication is an achievable objective for any livestock disease, provided that the epidemiology is uncomplicated and the necessary tools, resources and policies are available. Eradication at a national level inevitably reflects national priorities, whereas global eradication requires a level of international initiative and leadership to integrate these tools into a global framework, aimed first at suppressing transmission across all infected areas and concluding with a demonstration thatthis has been achieved. With a simple transmission chain and the environmental fragility of the virus, rinderpest has always been open to control and even eradication within a zoosanitary approach. However, in the post-1945 drive for more productive agriculture, national and global vaccination programmes became increasingly relevant and important. As rinderpest frequently spread from one region to another through trade-related livestock movements, the key to global eradication was to ensure that such vaccination programmes were carried out in a synchronised manner across all regions where the disease was endemic - an objective to which the European Union, the United States Agency for International Development, the International Atomic Energy Agency, the African Union-Interafrican Bureau of Animal Resources, FA0 and OIE fully subscribed. This article provides a review of rinderpest eradication, from the seminal work carried out by Giovanni Lancisi in the early 18th Century to the global declaration in 2011.

The National Climate Assessment-Land Data Assimilation System (NCA-LDAS) is an Integrated Terrestrial Water Analysis, and is one of NASAs contributions to the NCA of the United States. The NCA-LDAS has undergone extensive development, including multi-variate assimilation of remotely-sensed water states and anomalies as well as evaluation and verification studies, led by the Goddard Space Flight Centers Hydrological Sciences Laboratory (HSL). The resulting NCA-LDAS data have recently been released to the general public and include those from the Noah land-surface model (LSM) version 3.3 (Noah-3.3) and the Catchment LSM version Fortuna-2.5 (CLSM-F2.5). Standard LSM output variables including soil moistures temperatures, surface fluxes, snow cover depth, groundwater, and runoff are provided, as well as streamflow using a river routing system. The NCA-LDAS data are archived at and distributed by the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC). The data can be accessed via HTTP, OPeNDAP, Mirador search and download, and NASA Earth data Search. To further facilitate access and use, the NCA-LDAS data are integrated into the NASA Giovanni, for quick visualization and analysis, and into the Data Rods system, for retrieval of time series of long time periods. The temporal and spatial resolutions of the NCA-LDAS data are, respectively, daily-averages and 0.125x0.125 degree, covering North America (25N 53N; 125W 67W) and the period January 1979 to December 2015. The data files are in self-describing, machine-independent, CF-compliant netCDF-4 format.

With the recent attention to climate change and proliferation of remote-sensing data utilization, climate model and various environmental monitoring and protection applications have begun to increasingly rely on satellite measurements. Research application users seek good quality satellite data, with uncertainties and biases provided for each data point. However, different communities address remote sensing quality issues rather inconsistently and differently. We describe our attempt to systematically characterize, capture, and provision quality and uncertainty information as it applies to the NASA MODIS Aerosol Optical Depth data product. In particular, we note the semantic differences in quality/bias/uncertainty at the pixel, granule, product, and record levels. We outline various factors contributing to uncertainty or error budget; errors. Web-based science analysis and processing tools allow users to access, analyze, and generate visualizations of data while alleviating users from having directly managing complex data processing operations. These tools provide value by streamlining the data analysis process, but usually shield users from details of the data processing steps, algorithm assumptions, caveats, etc. Correct interpretation of the final analysis requires user understanding of how data has been generated and processed and what potential biases, anomalies, or errors may have been introduced. By providing services that leverage data lineage provenance and domain-expertise, expert systems can be built to aid the user in understanding data sources, processing, and the suitability for use of products generated by the tools. We describe our experiences developing a semantic, provenance-aware, expert-knowledge advisory system applied to NASA Giovanni web-based Earth science data analysis tool as part of the ESTO AIST-funded Multi-sensor Data Synergy Advisor project.

Crafting glass vessels: current research on the ancient glass collections in the Freer Gallery of Art, Washington, D.C.

Nagel, Alexander; McCarthy, Blythe; Bowe, Stacy

Our knowledge of glass production in ancient Egypt has been well augmented by the publication of recently excavated materials and glass workshops, but also by more recent materials analysis, and experiments of modern glass-makers attempting to reconstruct the production process of thin-walled coreformed glass vessels. From the mounting of a prefabricated core to the final glass product our understanding of this profession has much improved. The small but well preserved glass collection of the Freer Gallery of Art in Washington, D.C. is a valid tool for examining and studying the technology and production of ancient Egyptian core formed glass vessels. Charles Lang Freer (1854-1919) acquired most of the material from Giovanni Dattari in Cairo in 1909. Previously the glass had received only limited discussion, suggesting that most of these vessels were produced in the 18th Dynasty in the 15th and 14th centuries BCE, while others date from the Hellenistic period and later. In an ongoing project we conducted computed radiography in conjunction with qualitative x-ray fluorescence analysis on a selected group of vessels to understand further aspects of the ancient production process. This paper will provide an overview of our recent research and present our data-gathering process and preliminary results. How can the examinations of core formed glass vessels in the Freer Gallery contribute to our understanding of ancient glass production and technology? By focusing on new ways of looking at old assumptions using the Freer Gallery glass collections, we hope to increase understanding of the challenges of the production process of core-vessel technology as represented by these vessels.

Goddard Earth Sciences Data and Information Services Center (GES DISC) has been providing access to scientific data sets since 1990s. Beginning as one of the first Earth Observing System Data and Information System (EOSDIS) archive centers, GES DISC has evolved to offer a wide range of science-enabling services. With a growing understanding of needs and goals of its science users, GES DISC continues to improve and expand on its broad set of data discovery and access tools, sub-setting services, and visualization tools. Nonetheless, the multitude of the available tools, a partial overlap of functionality, and independent and uncoupled interfaces employed by these tools often leave the end users confused as of what tools or services are the most appropriate for a task at hand. As a result, some the services remain underutilized or largely unknown to the users, significantly reducing the availability of the data and leading to a great loss of scientific productivity. In order to improve the accessibility of GES DISC tools and services, we have designed and implemented UUI, the Unified User Interface. UUI seeks to provide a simple, unified, and intuitive one-stop shop experience for the key services available at GES DISC, including sub-setting (Simple Subset Wizard), granule file search (Mirador), plotting (Giovanni), and other services. In this poster, we will discuss the main lessons, obstacles, and insights encountered while designing the UUI experience. We will also present the architecture and technology behind UUI, including NodeJS, Angular, and Mongo DB, as well as speculate on the future of the tool at GES DISC as well as in a broader context of the Space Science Informatics.

Recently, attention was drawn to a role for progranulin in the central nervous system with the identification of mutations in the progranulin gene (GRN) as an important cause of frontotemporal lobar degeneration. GRN mutations are associated with a strong reduction of circulating progranulin and widely variable clinical phenotypes: thus, the dosage of plasma progranulin is a useful tool for a quick and inexpensive large-scale screening of carriers of GRN mutations. To establish the best cutoff threshold for normal versus abnormal levels of plasma progranulin. 309 cognitively healthy controls (25-87 years of age), 72 affected and unaffected GRN+ null mutation carriers (24-86 years of age), 3 affected GRN missense mutation carriers, 342 patients with neurodegenerative diseases and 293 subjects with mild cognitive impairment were enrolled at the Memory Clinic, IRCCS S. Giovanni di Dio-Fatebenefratelli, Brescia, Italy, and at the Alzheimer Unit, Ospedale Maggiore Policlinico and IRCCS Istituto Neurologico C. Besta, Milan, Italy. Plasma progranulin levels were measured using an ELISA kit (AdipoGen Inc., Seoul, Korea). Plasma progranulin did not correlate with age, gender or body mass index. We established a new plasma progranulin protein cutoff level of 61.55 ng/ml that identifies, with a specificity of 99.6% and a sensitivity of 95.8%, null mutation carriers among subjects attending to a memory clinic. Affected and unaffected GRN null mutation carriers did not differ in terms of circulating progranulin protein (p = 0.686). A significant disease anticipation was observed in GRN+ subjects with the lowest progranulin levels. We propose a new plasma progranulin protein cutoff level useful for clinical practice.

Annals of morphology. Atavisms: phylogenetic Lazarus?

Dedication: with highest respect and affection to Prof. Giovanni Neri on the eve of his official administrative retirement as Chair of the Institute of Medical Genetics of the Università Cattolica of Rome for leadership in medical genetics and medical science and friendship for decades. The concept "atavism," reversion, throwback, Rückschlag remains an epistemological challenge in biology; unwise or implausible over-interpretation of a given structure as such has led some to almost total skepticism as to its existence. Originating in botany in the 18th century it became applied to zoology (and humans) with increasing frequency over the last two centuries such that the very concept became widely discredited. Presently, atavisms have acquired a new life and reconsideration given certain reasonable criteria, including: Homology of structure of the postulated atavism to that of ancestral fossils or collateral species with plausible soft tissue reconstructions taking into account relationships of parts, obvious sites of origin and insertion of muscles, vascular channels, etc. Most parsimonious, plausible phylogenetic assumptions. Evident rudimentary or vestigial anatomical state in prior generations or in morphogenesis of a given organism. Developmental instability in prior generations, that is, some closely related species facultatively with or without the trait. Genetic identity or phylogenomic similarity inferred in ancestors and corroborated in more or less closely related species. Fluctuating asymmetry may be the basis for the striking evolutionary diversification and common atavisms in limbs; however, strong selection and developmental constraints would make atavisms in, for example, cardiac or CNS development less likely. Thus, purported atavisms must be examined critically in light of the above criteria. © 2013 Wiley Periodicals, Inc.

Galileo as a Patient

The clinical history of Galileo, as it turns out from hundred letters he wrote and received, is so informative as to make it possible to delineate the natural history of his body. It is well known that he suffered from recurrent episodes of fever (terzana) since 1606, when he was in Florence as guest of Cristina Lorena for education of the future granduke Cosimo II. By reading signs and symptoms he reported several times, it is clear that he had various diseases (rheumatism, haemorroids, kidney stones, arrhythmias). When in December 1632, at the age of 68, Galileo delayed his journey to Rome claiming sickness, Pope Urban VIII committed 3 physicians to examine him. They reported that Galileo was affected by "pulsus intermittens" (most probably atrial fibrillation), large hernia at risk of rupture, dizziness, diffuse pain, hypochondriacal melancholy as a consequence of the "declining age". It was in February 1637 that he started to have eye disease with lacrimation and progressive loss of sight, which in 10 months led to loose at first the right eye and then also the left one. According to the consultation, asked at distance to Giovanni Trullio on February 1538 in Rome, the diagnosis of blindness due to bilateral uveitis came out. Keeping with the current medicine, the illnes might have been explained in the setting of an immune rheumatic disease (Reiter's syndrome). The cause of Galileo's death, which occurred on 8 January 1642 at the age of 78, is not known since it was not submitted to autopsy. We can speculate cardiac death due to pneumonia complicating congestive heart failure.

Geochemical Analysis for Sedimentary Emerald Mineralization in Western Emerald belt, Colombia

1Gabriel Felipe Nino Vasquez and 1Sheng-Rong Song 1Department of Geosciences, National Taiwan University Colombia hosts a large quantity of mineral resources due to its complex tectonic arrangement, and emerald deposits are one of the most representatives for the country. Emeralds in Colombia occur mainly in black shale, and are located in eastern Andes Cordillera with two parallel belts separated by approximately 130 Km: the Western belt (WB) and the Eastern belt (EB). The geological, mineralogical and tectonic features from these belts are quite similar (Buenaventura 2002). Previous researchers concluded that emeralds in Colombia came from hydrothermal sedimentary processes without any magmatic influence, and suggested that the source of Cr, V and Be (which are important components of the beryl) was the host rock. According to their results, the process which allowed the shale to release these cations was the metasomatism (albitization and carbonization), which was resulted from the interaction between the rocks and the alkaline brines. Fractures and fault planes originated by these tectonic movements were fulfilled by enriched fluids, which they allowed emeralds and the other minerals precipitation with decreasing alkalinity and pressure (Giuliani et al. 1994). However, there were several pitfalls of conclusions drawn from previous researches. Firstly, Cr and V were widely distributed and come from mafic and ultramafic rocks, and Be was mostly found in pegmatites, finding these elements in sedimentary rocks suggest that probably the ultramafic rocks occurred not far from the deposits. Secondly, there was an inconsistency in the estimated temperatures of emeralds formation, i.e. temperature of hydrothermal sedimentary deposits was only 200° C, while laboratory analysis showed that the formation of emeralds was higher than 300° C. Therefore, there might still be an allocthonus influence on emerald formation that significantly increases the temperature. This

consists of work devoted to the current status of the theory and measurements related to Casimir forces. Readers must be warned that some topics in this field of research remain controversial (especially the dependence on temperature): they can and do generate debates that sometimes become quite heated. These controversies are reflected in the papers. We believe that at present it is not the business of conference organisers to adjudicate such issues, and hope that detailed expositions of different approaches and different points of view will help readers to formulate their own, and will eventually lead to a better understanding of the problems and of the solutions proposed. The other three groups contain contributions bearing on (1) topics related to causes and consequences of Casimir effects in quantum field theory and gravitation; (2) the so-called dynamical (or nonstationary) Casimir effect and motion-induced radiation, (3) some new manifestations and applications of the Casimir effect. We are grateful to the authors for making their papers so interesting; to the referees for their careful reading of the initial versions, and for their many helpful comments and suggestions; to the Institute of Physics for its kindness in offering to publish these Proceedings in Journal of Physics: Conference Series; and to the Institute of Physics office at the Lebedev Physical Institute in Moscow for essential help in the preparation of this volume. On behalf of the participants of the workshop, we thank the direction and staff of the ICCMP for their splendid organization of the event.

2015-01-01

Severe natural phenomena such as hurricane, volcano, blizzard, flood and drought have the potential to cause immeasurable property damages, great socioeconomic impact, and tragic loss of human life. From searching to assessing the Big, i.e., massive and heterogeneous scientific data (particularly, satellite and model products) in order to investigate those natural hazards, it has, however, become a daunting task for Earth scientists and applications researchers, especially during recent decades. The NASA Goddard Earth Sciences Data and Information Service Center (GES DISC) has served Big Earth science data, and the pertinent valuable information and services to the aforementioned users of diverse communities for years. In order to help and guide our users to online readily (i.e., with a minimum effort) acquire their requested data from our enormous resource at GES DISC for studying their targeted hazard event, we have thus initiated a Bundle Data approach in 2014, first targeting the hurricane event topic. We have recently worked on new topics such as volcano and blizzard. The bundle data of a specific hazard event is basically a sophisticated integrated data package consisting of a series of proper datasets containing a group of relevant (knowledge--based) data variables readily accessible to users via a system-prearranged table linking those data variables to the proper datasets (URLs). This online approach has been developed by utilizing a few existing data services such as Mirador as search engine; Giovanni for visualization; and OPeNDAP for data access, etc. The online Data Cookbook site at GES DISC is the current host for the bundle data. We are now also planning on developing an Automated Virtual Collection Framework that shall eventually accommodate the bundle data, as well as further improve our management in Big Data.

Data services to support precipitation applications are important for maximizing the NASA TRMM (Tropical Rainfall Measuring Mission) and the future GPM (Global Precipitation Mission) mission's societal benefits. TRMM Application examples using data services at the NASA GES DISC, including samples from users around the world will be presented in this poster. Precipitation applications often require near-real-time support. The GES DISC provides such support through: 1) Providing near-real-time precipitation products through TOVAS; 2) Maps of current conditions for monitoring precipitation and its anomaly around the world; 3) A user friendly tool (TOVAS) to analyze and visualize near-real-time and historical precipitation products; and 4) The GES DISC Hurricane Portal that provides near-real-time monitoring services for the Atlantic basin. Since the launch of TRMM, the GES DISC has developed data services to support precipitation applications around the world. In addition to the near-real-time services, other services include: 1) User friendly TRMM Online Visualization and Analysis System (TOVAS; URL: http://disc2.nascom.nasa.gov/Giovanni/tovas/); 2) Mirador (http://mirador.gsfc.nasa.gov/), a simplified interface for searching, browsing, and ordering Earth science data at GES DISC. Mirador is designed to be fast and easy to learn; 3) Data via OPeNDAP (http://disc.sci.gsfc.nasa.gov/services/opendap/). The OPeNDAP provides remote access to individual variables within datasets in a form usable by many tools, such as IDV, McIDAS-V, Panoply, Ferret and GrADS; and 4) The Open Geospatial Consortium (OGC) Web Map Service (WMS) (http://disc.sci.gsfc.nasa.gov/services/wxs_ogc.shtml). The WMS is an interface that allows the use of data and enables clients to build customized maps with data coming from a different network.

The empire of the ear: Freud's problem with music.

PubMed

Cheshire, N M

1996-12-01

Freud's difficulty in appreciating music, even though he seems to have been one of Charcot's 'auditifs' and had given auditory imagery a central place in his psychology, is re-examined in the light of his dealings with various distinguished musicians, and with special reference to the musical career of 'Little Hans'. The author argues that Freud's exaggeration of his difficulty, combined with his ability to enjoy certain operas and his use of musical metaphors in the context of theory and therapy, confirms his own intuition of a conflict rather than a simple deficiency. This conflict is examined with reference to the theories of Eissler and of Vitz, and in the light of his own interest in classical Greek culture and in the nature of Art. Since opera was perhaps the only form of music that Freud could readily enjoy, the relation between words and melody in that genre is addressed. The significance for Freud of the specific works and passages that he mentions throughout his writings is examined in the light of some of his own theoretical concepts: (a) with special reference to 'oedipal' features, to the dynamics of 'eros' and 'thanatos', and to the balance between the 'primary' and 'secondary' processes in artistic creativity; and (b) as exemplified in his favourite operas 'The Marriage of Figaro', 'Don Giovanni', 'Carmen' and 'The Mastersingers'. The parts played, in his problem with music, by his envy of the artist's intuitive talent for seduction and by his own 'acoustic atrophy' are also considered. He is defended against the recent charge that, in order to avoid having to cede primacy to others on points of psychology, he deliberately misrepresented how much he knew about music.

This thesis is the result of my work as research fellow at IASF-MI, Milan section of the Istituto di Astrofisica Spaziale e Fisica Cosmica, part of INAF, Istituto Nazionale di Astrofisica. This work started in January 2006 in the context of the PhD school program in Astrophysics held at the Physics Department of Universita' degli Studi di Milano under the supervision of Aniello Mennella. The main topic of my work is the software modelling of the Low Frequency Instrument (LFI) radiometers. The LFI is one of the two instruments on-board the European Space Agency Planck Mission for high precision measurements of the anisotropies of the Cosmic Microwave Background (CMB). I was also selected to participate at the International Doctorate in Antiparticles Physics, IDAPP. IDAPP is funded by the Italian Ministry of University and Research (MIUR) and coordinated by Giovanni Fiorentini (Universita' di Ferrara) with the objective of supporting the growing collaboration between the Astrophysics and Particles Physics communities. It is an international program in collaboration with the Paris PhD school, involving Paris VI, VII and XI Universities, leading to a double French-Italian doctoral degree title. My work was performed with the co-tutoring of Jean-Michel Lamarre, Instrument Scientist of the High Frequency Instrument (HFI), the bolometric instrument on-board Planck. Thanks to this collaboration I had the opportunity to work with the HFI team for four months at the Paris Observatory, so that the focus of my activity was broadened and included the study of cross-correlation between HFI and LFI data. Planck is the first CMB mission to have on-board the same satellite very different detection technologies, which is a key element for controlling systematic effects and improve measurements quality.

The NASA Goddard Earth Sciences Data and Information Service Center (GES DISC) has provided massive Earth science data, information, and services to diverse research communities and general publics for decades. How to genuinely maintain our overall data and service quality, as well as continually improve serving our users (such as research scientists, applications scientists, general publics, and students) with better data services have always been our primary goal. A synoptic metric analysis involving the data and service usages by our diverse user communities at GES DISC that should help us better understand our overall data services, as well as further improve them has therefore been performed. The results of this metrics analysis, along with its purpose, which will be presented at the meeting can be genuinely categorized into the "Five Ws and One H" concept, seemingly cliché, yet by all means pertinent and useful. * What: Metrics involving our archived and served data products addressing useful info's such as "volume of data in archive"; "number of granules in archive"; "volume of data distributed"; "number of granules distributed"; "number of distinct users"; and "relative data usage". a) Remote Sensing: GPM/TRMM, AIRS, OCO-2, etc. b) Modeling: MERRA-2/MERRA, NLDAS, GLDAS, etc. c) Projects: MEaSUREs-2006, MEaSUREs-2012, etc. * Why: The goal: a synoptic (overall) metric analysis should help us better understand and learn from our overall user and data services so that we may further improve them accordingly. * When: Metrics for data during the past decade or longer. Trends or/and usages for specific seasons (e.g., summer or holidays) may also be studied. * Where: Maps showing users from global, continents, countries, and specific area of interests. * Who: Users from various domains/backgrounds: .gov, .edu, .com, .org, anonymous, countries. * How: Data download or service usage via HTTP, FTP, Giovanni, etc.

Lessons Learned from a Decade of Serving Data to Students and the Public

NASA holds petabytes of Earth science data from a fleet of satellites going back decades. While these data can be invaluable for use in STEM education and communication (E/C), the simple fact that the archive is public is not enough. The key to successful use is to provide technological tools in strategic combination with best practices to meet the needs of various audiences. Students and teachers need access points that are specifically tailored to meet the technology resources in the classroom; citizen scientists need to feel a connection to NASA, easy-to-use technological interfaces, and are motivated by contributing to real research activities; the general public needs short, focused, easily digested tidbits. NASA's Earth science E/C teams have developed strategies combining audience knowledge with new technical capabilities through programs like MY NASA DATA, S'COOL, Earth Observatory, Giovanni, climate.gov, etc. The capability to offer a range of resources targeted to specific audience needs has advanced along several fronts over the last decade through use of the following key strategies: Regularly publishing articles, fact sheets and image captions written with greater detail than media releases to connect basic science concepts with current NASA research. Providing for differing levels of engagement, with basic, intermediate and advanced data access tools as well as lesson plans for grades K-2 through high school. Facilitating the important scientific process of asking questions once students are actively engaged though exploration and manipulation of current Earth data delivered through desktop and mobile apps.. Providing curated data sets that students can more easily interpret. Assessing users' needs through ongoing formative evaluation. Using Analytics to make data-driven decisions about technologies and approaches. We will survey the range of approaches to enabling data use for STEM E/C and will share some of the key lessons learned.

The present study aimed to provide practical guidelines for palliative treatment of advanced carcinoma of the pancreas (CAP) with the 2D technique. Fifteen patients with locally advanced CAP consecutively treated with radiation therapy at the Radiation Oncology Center, Research and Care Foundation 'Giovanni Paolo II' (Campobasso, Italy) underwent computed tomography simulation in supine position. Definition of the clinical target volume (CTV) included the head and body of the pancreas, and the retropancreatic space. The planning target volume was defined by adding a margin of 14 mm to the CTV in the cranio-caudal direction and of 11 mm in radial direction. For each patient, 3 treatment plans were calculated using a cobalt source, 6 MV photons and 15 MV photons (box technique). Beams were drawn using the primary collimators without using multileaf collimators, and progressively optimized in order to respect the minimum dose (D min >90%) constraint. Once the final plan was achieved, distances of the fields edges from a set of reference points (bony or duodenal landmarks) were measured. Using this technique, 15 anterior-posterior and postero-anterior (AP-PA) beams and 15 pairs of lateral-lateral (LL) beams were defined for the different patients. Finally, the single minimal AP-PA and LL beams able to include the 15 sets of AP-PA and LL beams were defined. The results of this analysis are reported in tabular form. Guidelines are provided for treatment based on cobalt unit or Linear accelerator (both 6 and 15 MV photons). This study provides information regarding field size and position. A dosimetric study has been planned to identify the dose to be administered with this technique taking into account current dose-volume constraints.

Moon-Struck: Artists Rediscover Nature And Observe

NASA Astrophysics Data System (ADS)

Pasachoff, Jay M.; Olson, Roberta J. M.

We discuss rare early depictions of the Moon by artists who actually observed Earth's nearest neighbor rather than relying on stylized formulas. The earliest, from the 14th and 15th centuries, reveal that revolutionary advances in both pre-telescopic astronomy and naturalistic painting could go hand-in-hand. This link suggests that when painters observed the world, their definition of world could also include the heavens and the Moon. Many of the artists we discuss - e.g., Pietro Lorenzetti, Giotto, and Jan Van Eyck - actually studied the Moon, incorporating their studies into several works. We also consider the star map on the dome over the altar in the Old Sacristy of San Lorenzo, Florence (c. 1442), whose likely advisor was Toscanelli. In addition, we examine representations by artists who painted for Popes Julius II and Leo X - Raphael and Sebastiano del Piombo, both of whom were influenced by individuals at the papal court, such as the astronomer, painter, and cartographer Johann (Giovanni) Ruysch and Leonardo da Vinci. We also discuss Leonardo's pre-telescopic notes and lunar drawings as they impacted on art and science in Florence, where Galileo would study perspective and chiaroscuro. Galileo's representations of the Moon (engraved in his Sidereus Nuncius, 1610) are noted, together with those by Harriot and Galileo's friend, the painter Cigoli. During the 17th century, the Moon's features were telescopically mapped by astronomers with repercussions in art, e.g., paintings by Donati Creti and Raimondo Manzini as well as Adam Elsheimer. Ending with a consideration of the 19th-century artists/astronomers John Russell and John Brett and early lunar photography, we demonstrate that artistic and scientific visual acuity belonged to the burgeoning empiricism of the 14th, 15th, and 16th centuries that eventually yielded modern observational astronomy.

Some historical reflections on the neural control of locomotion.

PubMed

Clarac, François

2008-01-01

Thought on the neural control of locomotion dates back to antiquity. In this article, however, the focus is more recent by starting with some major 17th century concepts, which were developed by René Descartes, a French philosopher; Thomas Willis, an English anatomist; and Giovanni Borelli, an Italian physiologist and physicist. Each relied on his personal expertise to theorize on the organization and control of movements. The 18th and early 19th centuries saw work on both the central and peripheral control of movement: the former most notably by Johann Unzer, Marie Jean-Pierre Flourens and Julien-Jean-César Legallois, and the latter by Unzer, Jirí Procháska and many others. Next in the 19th century, neurologists used human locomotion as a precise tool for characterizing motor pathologies: e.g., Guillaume Duchenne de Boulogne's description of locomotor ataxia. Jean-Martin Charcot considered motor control to be organized at two levels of the central nervous system: the cerebral cortex and the spinal cord. Maurice Philippson's defined the dog's step cycle and considered that locomotion used both central and reflex mechanisms. Charles Sherrington explained that locomotor control was usually thought to consist of a succession of peripheral reflexes (e.g., the stepping reflexes). Thomas Graham Brown's then contemporary evidence for the spinal origin of locomotor rhythmicity languished in obscurity until the early 1960s. By then the stage was set for an international assault on the neural control of locomotion, which featured research conducted on both invertebrate and vertebrate animal models. These contributions have progressively became more integrated and interactive, with current work emphasizing that locomotor control involves a seamless integration between central locomotor networks and peripheral feedback.

Function and structure in early modern muscular mechanics. Four episodes and a dialogue between Stensen and Borelli on two chief muscular systems.

PubMed

Kardel, T

1997-01-01

The dispute on the movement of skeletal muscles in 1667 between Giovanni Alfonso Borelli, who maintained the ancient movement caused by inflation theory, and Niels Stensen (Nicolaus Steno), who proposed the first recorded theory of fibre contraction, had far reaching implications for understanding the relation between muscle morphology and function. A dialogue is reconstructed from citations from the two authors' main works. They had a similar dispute on the movement of the heart along the lines of the debate in the 1630s between William Harvey favouring contraction and René Descartes favouring swelling. Evidence is provided for the delayed general acceptance of fibre contraction in both heart and skeletal muscles. It is shown that the inflation interpretation of muscular mechanics elaborated by Borelli, Johann Bernoulli, his son Daniel, and by others, was maintained from ancient authors and Descartes in part due to a conceptual block resulting from the mechanical philosophy that denied any force of attraction in nature. The alternative theory, that of fibre contraction, was thought of as self-motion, which violated an accepted mechanical principle and therefore was rejected. In the mid-18th century, Albrecht von Haller recorded no microscopic structures in support of inflation. He adopted the view that contraction in fibres of muscles is generated through an 'irritability'. Research on this entity has taken place ever since with a clear preponderance of studies on single fibre properties and subcellular structures. Haller did not, however, refer to the original contribution of Stensen on fibre contraction. Haller even rejected Stensen's functional architecture of skeletal muscle. This structure, now called the unipennate, or semipennate, actuator, was overlooked and had to await confirmation by anatomical rediscovery and pragmatic demonstration through successful applications in computer models of muscular contraction in the 1980s.

The Ottoman Empire maintained close relations with the neighbouring Italian city states in the 16th and 17th century. Yacub Pasha (1425-1481), personal physician of Mehmed II the Conqueror, was an Italian Jew who advanced to the title of pasha and vizier. Domenico Hierosolimitano (ca. 1552-1622), the third physician to Sultan Murad III, was a Jerusalemite rabbi. His book is an important source about everyday life and medical practice in Istanbul at the time. Nuh bin Abd al-Mennab (1627-1707), also of Italian stock, was the Chief Physician of the Ottoman Empire, who translated a pharmacopoeia into Turkish. In the same century, two Italians, Israel Conegliano (Conian) and Tobia Cohen became private physicians to leading Ottoman pashas and the Grand Vizier. A. Vuccino (1829-1893) and Antoine Calleja Pasha (1806-1893) taught at the Istanbul Medical School. Italy was a favoured country for medical education during the early period of Ottoman westernisation. Sanizade Mehmet Ataullah Efendi (1771-1826) translated the first medical book printed in the Ottoman Empire from Italian into Turkish. Mustafa Behcet Efendi (1774-1833), chief physician to the Sultan and the founder of the first western medical school in Turkey, translated several medical books from Italian into Turkish. The first printed pharmacopeia in the Ottoman Empire was also originally Italian In the 19th century, Edouard Ottoni and his son Giuseppe Ottoni were well-known military pharmacists, both under the name of Faik Pasha. Probably the most influential physician of Italian origin was Giovanni Battista Violi (1849-1928), who had practiced paediatrics in Turkey for more than fifty years. Violi was the founder of the first children's hospital, the first vaccine institute, and the first paediatric journal in the Ottoman Empire.

"Bundle Data" Approach at GES DISC Targeting Natural Hazards

Severe natural phenomena such as hurricane, volcano, blizzard, flood and drought have the potential to cause immeasurable property damages, great socioeconomic impact, and tragic loss of human life. From searching to assessing the "Big", i.e., massive and heterogeneous scientific data (particularly, satellite and model products) in order to investigate those natural hazards, it has, however, become a daunting task for Earth scientists and applications researchers, especially during recent decades. The NASA Goddard Earth Sciences Data and Information Service Center (GES DISC) has served "Big" Earth science data, and the pertinent valuable information and services to the aforementioned users of diverse communities for years. In order to help and guide our users to online readily (i.e., with a minimum effort) acquire their requested data from our enormous resource at GES DISC for studying their targeted hazard/event, we have thus initiated a "Bundle Data" approach in 2014, first targeting the hurricane event/topic. We have recently worked on new topics such as volcano and blizzard. The "bundle data" of a specific hazard/event is basically a sophisticated integrated data package consisting of a series of proper datasets containing a group of relevant ("knowledge-based") data variables readily accessible to users via a system-prearranged table linking those data variables to the proper datasets (URLs). This online approach has been developed by utilizing a few existing data services such as Mirador as search engine; Giovanni for visualization; and OPeNDAP for data access, etc. The online "Data Cookbook" site at GES DISC is the current host for the "bundle data". We are now also planning on developing an "Automated Virtual Collection Framework" that shall eventually accommodate the "bundle data", as well as further improve our management in "Big Data".

Some historical crossroads between astronomy and visual neuroscience

NASA Astrophysics Data System (ADS)

Berlucchi, G.

The histories of astronomy and visual neuroscience share some important events. Observation of the sky provided early basic information about visual acuity and sensitivity to light and their variations at different retinal locations. Some of the early tests of visual functions were inspired by astronomical knowledge existing since antiquity and possibly since human prehistory. After science became a hallmark of human civilization, astronomy played a crucial part in the discovery of the laws of nature. At the turn of the 19th century, astronomers discovered interindividual variability in detecting the time of stellar transit and tried to measure the so-called personal equation, a supposedly inherent individual bias in making observations, judgements and measurements. Convinced that the reliability of scientific observations depended on the reliability of the observer, they were the first scientists to realize that studying man and human psychophysiology was essential for achieving accuracy and objectivity in astronomy and other sciences alike. There is general consensus that the science of experimental psychology grew out of astronomy and physiology in connection with the development of the reaction time method and the so-called mental chronometry. The crucial role of the observer in astronomical observations appears to have been neglected by astronomers in the second half of the 19th century after Giovanni Schiaparelli described ``canals" on the surface of the planet Mars. Percival Lowell and others thought that these canals had been constructed by a Martian intelligent population in order to distribute water from the polar regions to the equatorial deserts on the planet. Since it has been ascertained that the Mars canals seen by Schiaparelli do not exist, some speculations are offered from a neuroscientific viewpoint as to why he and others were mistaken in their observations of Mars.

Integrating NASA Satellite Data Into USDA World Agricultural Outlook Board Decision Making Environment To Improve Agricultural Estimates

Teng, William; Shannon, Harlan; deJeu, Richard; Kempler, Steve

2012-01-01

The USDA World Agricultural Outlook Board (WAOB) is responsible for monitoring weather and climate impacts on domestic and foreign crop development. One of WAOB's primary goals is to determine the net cumulative effect of weather and climate anomalies on final crop yields. To this end, a broad array of information is consulted. The resulting agricultural weather assessments are published in the Weekly Weather and Crop Bulletin, to keep farmers, policy makers, and commercial agricultural interests informed of weather and climate impacts on agriculture. The goal of the current project is to improve WAOB estimates by integrating NASA satellite precipitation and soil moisture observations into WAOB's decision making environment. Precipitation (Level 3 gridded) is from the TRMM Multi-satellite Precipitation Analysis (TMPA). Soil moisture (Level 2 swath and Level 3 gridded) is generated by the Land Parameter Retrieval Model (LPRM) and operationally produced by the NASA Goddard Earth Sciences Data and Information Services Center (GBS DISC). A root zone soil moisture (RZSM) product is also generated, via assimilation of the Level 3 LPRM data by a land surface model (part of a related project). Data services to be available for these products include GeoTIFF, GDS (GrADS Data Server), WMS (Web Map Service), WCS (Web Coverage Service), and NASA Giovanni. Project benchmarking is based on retrospective analyses of WAOB analog year comparisons. The latter are between a given year and historical years with similar weather patterns and estimated crop yields. An analog index (AI) was developed to introduce a more rigorous, statistical approach for identifying analog years. Results thus far show that crop yield estimates derived from TMPA precipitation data are closer to measured yields than are estimates derived from surface-based precipitation measurements. Work is continuing to include LPRM surface soil moisture data and model-assimilated RZSM.

The Ardito was a fighter as well as a competitor whose status as a 'warrior' was based on courage and superior physical performance: a superior man. In addition, his exuberant conduct, both on and off the battlefield, introduced a significant new sub-culture into post-war Italian society, contributing to the attachment of notable value to virility and Mussolini's cult of the 'strong man'. The purpose of this research is to analyse the impact of this 'arditismo' (spirit of daring) on the early post-war period in particular, including the different 'male image' of the Italian citizen, and to study the sense of virility in the transition from the liberal, easy-going 'Little Italy' of Giovanni Giolitti (1842-1928) to a manly, combative, and ambitious nation. Together with some of the vitalistic tendencies in the Futurist movement, the main characteristics and mentality of the ex-Ardito (former Special Forces) would thus be significantly influential in the ideology of nascent Fascism. Indeed, the 'arditismo' influence, together with the article and social movement known as Futurism would constitute the two most highly structured foundations of early Fascist culture, bringing a political and social revolution necessary to create a 'new man'. It was as if the Arditi and the new method of military training had transferred their experience from the military into civilian life, contributing to a renewal of the image of the Italian male in the collective imagination. Indirectly, the image of women would also begin to absorb and adapt to new sports models imported from abroad, which would create for the Italian Ardito, a grudgingly tolerated rival. The main sources for this paper are the archives of the Historical Office of the Army, advertising and manuals from the late nineteenth to the early twentieth century, placards and graphic publicity from books and journals or private collections, and exhibition catalogues.

NASA Earth Sciences Data Support System and Services for the Northern Eurasia Earth Science Partnership Initiative

The presentation describes data management of NASA remote sensing data for Northern Eurasia Earth Science Partnership Initiative (NEESPI). Many types of ground and integrative (e.g., satellite, GIs) data will be needed and many models must be applied, adapted or developed for properly understanding the functioning of Northern Eurasia cold and diverse regional system. Mechanisms for obtaining the requisite data sets and models and sharing them among the participating scientists are essential. The proposed project targets integration of remote sensing data from AVHRR, MODIS, and other NASA instruments on board US- satellites (with potential expansion to data from non-US satellites), customized data products from climatology data sets (e.g., ISCCP, ISLSCP) and model data (e.g., NCEPNCAR) into a single, well-architected data management system. It will utilize two existing components developed by the Goddard Earth Sciences Data & Information Services Center (GES DISC) at the NASA Goddard Space Flight Center: (1) online archiving and distribution system, that allows collection, processing and ingest of data from various sources into the online archive, and (2) user-friendly intelligent web-based online visualization and analysis system, also known as Giovanni. The former includes various kinds of data preparation for seamless interoperability between measurements by different instruments. The latter provides convenient access to various geophysical parameters measured in the Northern Eurasia region without any need to learn complicated remote sensing data formats, or retrieve and process large volumes of NASA data. Initial implementation of this data management system will concentrate on atmospheric data and surface data aggregated to coarse resolution to support collaborative environment and climate change studies and modeling, while at later stages, data from NASA and non-NASA satellites at higher resolution will be integrated into the system.

Studying Diurnal Variations of Aerosols with NASA MERRA-2 Reanalysis Data

Aerosols play an important role in atmospheric dynamics, climate variations, and Earth's energy cycle by altering the radiation balance in the atmosphere through interaction with clouds, providing fertilizer for forests and canopy, and as a supply of iron to the ocean over long time periods. Studies suggest that much of the feedback between dust aerosols and dynamics is associated with diurnal and synoptic scale variability. However, the lack of sub-daily resolution of aerosols from satellite observations makes it difficult to study the diurnal characteristics, especially over tropical and subtropical regions. Investigation of this topic utilizes over 37 years of simulated global aerosol products from NASA atmospheric reanalysis, in the second Modern-Era Retrospective analysis for Research and Applications (MERRA-2) data set, available from NASA Goddard Earth Science Data and Information Services Center (GES DISC). MERRA-2 covers the period 1980-present, and is continuing as an ongoing climate analysis. Aerosol assimilation is included throughout the period, using data from MODIS, MISR, AERONET, and AVHRR (in the pre-EOS period). The aerosols are assimilated using the MERRA-2 aerosol model, which interacts directly with radiation parameterization, and is radiatively coupled with atmospheric model dynamics in the Goddard Earth Observing System Model, Version 5 (GEOS-5). Hourly, monthly, and monthly diurnal data are available at spatial resolution of 0.5o x 0.625o (latitude x longitude). By using MERRA-2 hourly and monthly diurnal products, different aerosol diurnal variabilities are observed over North America, Africa, Asia, and Australia, that may be due to different meteorological conditions and aerosol sources. The presentation will also provide an overview of MERRA-2 data services at GES DISC, such as how to find and download data, and how to quickly visualize and analyze data online with Giovanni.

Among the known atmospheric constituents, aerosols still represent the greatest uncertainty in climate research. To understand the uncertainty is to bring altogether of observational (in-situ and remote sensing) and modeling datasets and inter-compare them synergistically for a wide variety of applications that can bring far-reaching benefits to the science community and the broader society. These benefits can best be achieved if these earth science data (satellite and modeling) are well utilized and interpreted. Unfortunately, this is not always the case, despite the abundance and relative maturity of numerous satellite-borne sensors routinely measure aerosols. There is often disagreement between similar aerosol parameters retrieved from different sensors, leaving users confused as to which sensors to trust for answering important science questions about the distribution, properties, and impacts of aerosols. NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) have developed multiple MAPSS (Multi-sensor Aerosol Products Sampling System) applications as a part of Giovanni (Geospatial Interactive Online Visualization and Analysis Interface) data visualization and analysis tool since 2007. The MAPSS database provides spatio-temporal statistics for multiple spatial spaceborne Level 2 aerosol products (MODIS Terra, MODIS Aqua, MISR, POLDER, OMI, CALIOP, SeaWiFS Deep Blue, and VIIRS) sampled over AERONET ground stations. In this presentation, I will demonstrate a new visualization service (NASA Level 2 Data Quality Visualization, DQViz) supporting various visualization and data accessing capabilities from satellite Level 2 (MODIS/MISR/OMI) and long term assimilated aerosols from NASA Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2 displaying at their own native physical-retrieved spatial resolution. Functionality will include selecting data sources (e.g., multiple parameters under the same measurement), defining

In these times of rapidly increasing amounts of archived data, tools and data services that manipulate data and uncover nuggets of information that potentially lead to scientific discovery are becoming more and more essential. The Goddard Space Flight Center (GSFC) Earth Sciences (GES) Distributed Active Archive Center (DAAC) has made great strides in facilitating science and applications research by, in consultation with its users, developing innovative tools and data services. That is, as data users become more sophisticated in their research and more savvy with information extraction methodologies, the GES DAAC has been responsive to this evolution. This presentation addresses the tools and data services available and under study at the GES DAAC, applied to the Earth sciences atmospheric data. Now, with the data from NASA's latest Atmospheric Chemistry mission, Aura, being readied for public release, GES DAAC tools, proven successful for past atmospheric science missions such as MODIS, AIRS, TRMM, TOMS, and UARS, provide an excellent basis for similar tools updated for the data from the Aura instruments. GES DAAC resident Aura data sets are from the Microwave Limb Sounder (MLS), Ozone Monitoring Instrument (OMI), and High Resolution Dynamics Limb Sounder (HIRDLS). Data obtained by these instruments afford researchers the opportunity to acquire accurate and continuous visualization and analysis, customized for Aura data, will facilitate the use and increase the usefulness of the new data. The Aura data, together with other heritage data at the GES DAAC, can potentially provide a long time series of data. GES DAAC tools will be discussed, as well as the GES DAAC Near Archive Data Mining (NADM) environment, the GIOVANNI on-line analysis tool, and rich data search and order services.

Use of alternative–complementary-medicine (CAM) in Calabrian children

PubMed Central

2012-01-01

Objective The use of complementary and alternative medicine (CAM) has not been widely studied among children in Italy. ISTAT-2005 survey showed a prevalence of 10% concerning children treated with CAM. The lack of data about the use of CAM in pediatrics in the South of Italy aimed us to conduct an epidemiological inquiry in Calabria. Methods The study has been conducted from 2009 and 2011 at the Pediatric Units of: University “Magna Graecia”- Catanzaro (CZ), Pugliese-Ciaccio Hospital-Catanzaro (CZ), Annunziata Hospital-Cosenza (CS), Jazzolino Hospital- ViboValentia (VV), Riuniti Hospitals- Reggio Calabria (RC) and San Giovanni di Dio Hospital- Crotone (KR). All information was collected through a questionnaire proposed to children’s parents admitted to these hospitals as out-patients or in-patients. Results 1387 parents were approached to complete the questionnaire. 21(1,5%) refused to answer. A total of 1366 questionnaire was analyzed: 378 at CZ , 450 at CS, 131 at KR, 201 at VV and 206 at RC, with a response rate of 98,5%. In total, the percentage of children using CAM varied from 18% in Crotone to 38% in Cosenza. The parents who used CAM for their children were older and with a higher education. Phytotherapy was preferred to homeopathy. The gastrointestinal pathologies and upper respiratory tract are those ones for which frequently parents recur to CAM. Of note we have not to disregard their use “ to strengthen” the immune system. In most of cases CAM have been prescribed by pediatrician. Conclusions Our study remarks that the use of CAM is increased dramatically among the calabrian children in the last years as well as in other countries. Pediatricians need to improve their knowledge about CAM in order to better manage the parental attitude. PMID:23231804

The preservice teachers enrolled in the EDUC 203 Introduction to Computer Instructional Technology course, primarily for elementary-level had created climate change educational lessons based upon their use of the NASA Data-enhanced Investigations for Climate Change Education (DICCE). NASA climate education datasets and tools were introduced to faculty of Minority Serving Institutions through a grant from the NASA Innovations in Climate Education program. These lessons were developed to study various ocean processes involving phytoplankton's chlorophyll production over time for specific geographic areas using the Giovanni NASA software tool. The pre-service teachers had designed the climate change content that will assist K-4 learners to identify and predict phytoplankton sources attributed to sea surface temperatures, nutrient levels, sunlight, and atmospheric carbon dioxide associated with annual chlorophyll production. From the EDUC 203 course content, the preservice teachers applied the three phases of the technology integration planning (TIP) model in developing their lessons. The Zunal website (http://www.zunal.com) served as a hypermedia tool for online instructional delivery in presenting the climate change content, the NASA climate datasets, and the visualization tools used for the production of elementary learning units. A rubric was developed to assess students' development of their webquests to meet the overall learning objectives and specific climate education objectives. Accompanying each webquest is a rubric with a defined table of criteria, for a teacher to assess students completing each of the required tasks for each lesson. Two primary challenges of technology integration for elementary pre-service teachers were 1) motivating pre-service teachers to be interested in climate education and 2) aligning elementary learning objectives with the Next Generation science standards of climate education that are non-existent in the Common Core State

The participants' conceptual clusters within the similarity matrix overlapped with the groupings created by the librarian, with a few differences. A total of 161 entries in the library shift log and 65 SRFs were analyzed to determine what resources were given to patrons. Most resources that patrons received were available online (61%), although almost half of these required special access (47%). The study findings suggest it is possible to replicate library functions in a Web app with a few exceptions that cannot be replicated online. These elements include access to journal articles or other content behind paywalls and the librarian's ability to encourage further discussion through empathy and active listening. Discussion with the librarian could serve to refine and predict needs through observing information seekers and to provide immediate connection to spiritual care and psychosocial support for patrons in distress. ©Janet Papadakos, Aileen Trang, Alaina B Cyr, Nazek Abdelmutti, Meredith E Giuliani, Michelle Snow, Tara McCurdie, Menaka Pulandiran, Sara Urowitz, David Wiljer.

NASA Earth Sciences Division (ESD), and its preceding Earth science organizations, has made great investments in the development and maintenance of data management systems, as well as information technologies, for the purpose of maximizing the use and usefulness of NASA generated Earth science data. Earth science information systems, evolving with the maturation and implementation of advancing technologies, reside at NASA data centers, known as Distributed Active Archive Centers (DAACs). With information management system infrastructure in place, and system data and user services already developed and operational, only very small delta costs are required to fully support data archival, processing, and data support services required by the recommended Decadal Study missions. This presentation describes the services and capabilities of the Goddard Space Flight Center (GSFC) Earth Sciences Data and Information Services Center (GES DISC) (one of NASAs DAACs) and their potential reuse for these future missions. After 14 years working with instrument teams and the broader science community, GES DISC personnel expertise in atmospheric, water cycle, and atmospheric modeling data and information services, as well as Earth science missions, information system engineering, operations, and user services have developed a series of modular, reusable data management components currently is use in several projects. The knowledge and experience gained at the GES DISC lend themselves to providing science driven information systems in the areas of aerosols, clouds, and atmospheric chemicals to be measured by recommended Decadal Survey missions. Available reusable capabilities include data archive and distribution (Simple, Scalable, Script-based, Science [S4] Product Archive aka S4PA), data processing (S4 Processor for Measurements aka S4PM), data search (Mirador), data browse, visualization, and analysis (Giovanni), and data mining services.

The Saturn System Through the Eyes of Cassini

Green, James

2017-01-01

More than 400 years ago, Galileo Galilei trained his homemade telescope on the night sky and observed that Saturn had two objects closely related to the planet extending on either side. At the time, in 1610, Galileo declared them to be moons. A few decades later, Saturn moon science accelerated at a dizzying pace. Christiaan Huygens first observed Saturn's largest moon Titan in 1655 and was the first to describe the extended moon-like features at Saturn as a disk of material sounding the planet. From 1671 to 1674, Giovanni Cassini discovered the moons lapetus, Rhea, Dione and Tethys. In 1675, Cassini discovered the gap in Saturn's rings that we now know as the Cassini Division. In the space age, before the Cassini-Huygens mission, we had only hints of the discoveries awaiting us at Saturn. Pioneer 11 and Voyagers 1 and 2 conducted flybys decades ago. But these quick encounters didn't allow time for more extensive research. NASA and the European Space Agency created a partnership to orbit a Saturn orbiter (Cassini) and a lander (Huygens) on Titan. Like its namesakes, the Cassini-Huygens mission not only discovered previously unknown moons, but it also helped us understand the science behind their formation, their interactions with the rings, and how truly diverse they are. The Cassini-Huygens mission revolutionized what we know about the Saturn system. The rings of Saturn, the moons, and the planet itself offer irresistible and inexhaustible subjects for intense study, and Cassini-Huygens did not disappoint. The Saturnian system proved to be a rich ground for science exploration and discoveries, and Cassini has been nothing short of a discovery machine. At the time Cassini plunged into Saturn at the end of its mission, it had observed the planet for a little less than half of a Saturn year. But it also orbited the gas giant 293 times, forever changing our understanding of the Saturn system and yielding tremendous insight for understanding the entire Solar System.

Astronomy in the Age of Leonardo.

Welther, B. L.

In the 1450s, when Leonardo da Vinci was born, horoscopes were still based primarily on the 13th-century tables developed in the court of Alfonso el Sabio of Spain. By the 15th century European astronomers were computing revised forms of the tables. In Italy, for example, Giovanni Bianchini of Ferrara completed his Tabulae astronomicae in the 1440s. It was finally published posthumously in Venice in 1495. By the 1480s Domenico Maria Novara, a professor of astronomy in Bologna, was publishing annual prognostications of eclipses, conjunctions, and other celestial phenomena. Against this background of traditional astronomy in Italy, two Florentines recorded observations of the sun and moon, comets, and meteorology. Paolo dal Pozzi Toscanelli flourished in the first half of the 15th century and Leonardo da Vinci in the last half. Their observations of celestial phenomena were not primarily for astronomical purposes; they were spinoffs of other pursuits such as medicine, astrology, optics, engineering, and studies of light and shadow. As a physician and cartographer, Toscanelli practiced astrology, studied omens, observed comets and plotted their paths on homemade maps. He also was associated with the construction of a gnomon at the top of the Duomo to observe the summer solstice. It was this project that may have brought him into contact with the young artisan, Leonardo da Vinci. As a painter, Leonardo's approach to science and engineering was to observe, sketch and analyze. His interest in light and shadow led him to notice how the earth, moon and planets all reflect sunlight. His extant manuscripts have geometric sketches for eclipses and for the phenomenon known as "old moon in new moon's arms." Unfortunately, because neither Toscanelli nor Leonardo published their observations, they made no impact on the history of astronomical thought or observation. Their contemporaries did not know or write about their work. Astronomers in the 16th century did not know about

Francesco Fontana and the birth of the astronomical telescope

NASA Astrophysics Data System (ADS)

Molaro, Paolo

2017-12-01

In the late 1620s the Neapolitan Francesco Fontana was the first to observe the sky using a telescope with two convex lenses, which he had manufactured himself. Fontana succeeded in drawing the most accurate maps of the Moon’s surface of his time, which were to become popular through a number of publications that appeared throughout Europe but did not acknowledge the author. At the end of 1645, in a state of declining health and pressed by the need to defend his authorship, Fontana carried out an intense observing campaign, the results of which he hurriedly collected in his Novae Coelestium Terrestriumque rerum Observationis (1646), the only public-cation he left for posterity. Fontana observed the Moon’s main craters, such as Tycho (which he referred to as ‘Fons Major’), their radial debris patterns and changes in their appearance due to the Moon’s motion. He observed the gibbosity of Mars at quadrature and, together with the Jesuit Giovanni Battista Zupus, he described the phases of Mercury. Fontana observed the two—and occasionally three—major bands of Jupiter, and inferred the rotation of the major planets Mars, Jupiter and Saturn, arguing that they could not be attached to an Aristotelian sky. He came close to revealing the ring structure of Saturn. He also suggested the presence of additional moons around Jupiter, Venus and Saturn, which prompted a debate that lasted more than a hundred years. In several places in his book Fontana claimed to have conceived the first positive eyepiece in 1608, and he provides a declaration by Zupus that his telescope was in use from 1614. Finally, we suggest that the telescopes depicted in the two paintings Allegory of Sight and Allegory of Sight and Smell by J. Brueghel the Elder might have been made by Fontana, and that he might by portrayed in the Allegory of Sight by Jusepe Ribera.

Despite an overwhelming history demonstrating the potential of hypothermia to rescue and preserve the brain and spinal cord after injury or disease, clinical trials from the last 50 years have failed to show a convincing benefit. This comprehensive review provides the historical context needed to consider the current status of clinical hypothermia research and a view toward the future direction for this field. For millennia, accounts of hypothermic patients surviving typically fatal circumstances have piqued the interest of physicians and prompted many of the early investigations into hypothermic physiology. In 1650, for example, a 22-year-old woman in Oxford suffered a 30-minute execution by hanging on a notably cold and wet day but was found breathing hours later when her casket was opened in a medical school dissection laboratory. News of her complete recovery inspired pioneers such as John Hunter to perform the first complete and methodical experiments on life in a hypothermic state. Hunter's work helped spark a scientific revolution in Europe that saw the overthrow of the centuries-old dogma that volitional movement was created by hydraulic nerves filling muscle bladders with cerebrospinal fluid and replaced this theory with animal electricity. Central to this paradigm shift was Giovanni Aldini, whose public attempts to reanimate the hypothermic bodies of executed criminals not only inspired tremendous scientific debate but also inspired a young Mary Shelley to write her novel Frankenstein. Dr. Temple Fay introduced hypothermia to modern medicine with his human trials on systemic and focal cooling. His work was derailed after Nazi physicians in Dachau used his results to justify their infamous experiments on prisoners of war. The latter half of the 20th century saw the introduction of hypothermic cerebrovascular arrest in neurosurgical operating rooms. The ebb and flow of neurosurgical interest in hypothermia that has since persisted reflect our continuing

Response of Tribal nations and Tribal communities to current and emerging climate change challenges requires active participation of stakeholders who have effective access to relevant data, information and analytical tools. The Tribal Lands Collaboratory (TLC), currently under development, is a joint effort between the American Indian Higher Education Consortium (AIHEC), the Environmental Systems Research Institute (Esri), and the National Ecological Observatory Network (NEON). The vision of the TLC is to create an integrative platform that enables coordination between multiple stakeholders (e.g. Tribal resource managers, Tribal College faculty and students, farmers, ranchers, and other local community members) to collaborate on locally relevant climate change issues. The TLC is intended to facilitate the transformation of data into actionable information that can inform local climate response planning. The TLC will provide the technical mechanisms to access, collect and analyze data from both internal and external sources (e.g. NASA's Giovanni climate data portal, Ameriflux or USA National Phenology Network) while also providing the social scaffolds to enable collaboration across Tribal communities and with members of the national climate change research community. The prototype project focuses on phenology, a branch of science focused on relationships between climate and the seasonal timing of biological phenomena. Monitoring changes in the timing and duration of phenological stages in plant and animal co­­­­mmunities on Tribal lands can provide insight to the direct impacts of climate change on culturally and economically significant Tribal resources . The project will leverage existing phenological observation protocols created by the USA-National Phenology Network and NEON to direct data collection efforts and will be tailored to the specific needs and concerns of the community. Phenology observations will be captured and managed within the Collaboratory

The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) is the home of processing, archiving, and distribution services for data from the Atmospheric Infrared Sounder (AIRS) mission. The AIRS mission is entering its 11th year of global observations of the atmospheric state, including temperature and humidity profiles, outgoing longwave radiation, cloud properties, and trace gases. The GES DISC, in collaboration with the AIRS Project, released data from the Version 6 algorithm in early 2013. The new algorithm represents a significant improvement over previous versions in terms of greater stability, yield, and quality of products. Among the most substantial advances are: improved soundings of Tropospheric and Sea Surface Temperatures; larger improvements with increasing cloud cover; improved retrievals of surface spectral emissivity; near-complete removal of spurious temperature bias trends seen in earlier versions; substantially improved retrieval yield (i.e., number of soundings accepted for output) for climate studies; AIRS-Only retrievals with comparable accuracy to AIRS+AMSU (Advanced Microwave Sounding Unit) retrievals; and more realistic hemispheric seasonal variability and global distribution of carbon monoxide. The GES DISC is working to bring the distribution services up-to-date with these new developments. Our focus is on popular services, like variable subsetting and quality screening, which are impacted by the new elements in Version 6. Other developments in visualization services, such as Giovanni, Near-Real Time imagery, and a granule-map viewer, are progressing along with the introduction of the new data; each service presents its own challenge. This presentation will demonstrate the most significant improvements in Version 6 AIRS products, such as newly added variables (higher resolution outgoing longwave radiation, new cloud property products, etc.), the new quality control schema, and improved retrieval yields.

The Baptistery of San Giovanni is one of the most important pieces of architecture in Florence. It is an octagonal building, encrusted with marble both internally and externally (including the pyramidal roof) and covered inside by a magnificent dome with sparkling gold mosaics. During Dante's time, it appeared much older than the other monuments, so its origins were considered as hailing straight from Florence's most remote and mythical history. Even though we have much more data now, scholars still disagree over the interpretations on the origin and construction sequence of the monument. Survey has always been considered a main instrument for understanding historical architecture, mostly from constructional and structural points of view. During the last century, the Baptistery was surveyed using both traditional techniques and the most up-to-date instruments available at the time, such as topography, close-range photogrammetry and laser scanning. So, a review of those early applications, even if partial or isolated, can significantly attest to the state of the art and evolution of survey techniques. During recent years, the Opera di Santa Maria del Fiore promoted new research and a wide range of diagnostic investigations aimed at acquiring greater knowledge of the monument in anticipation of the cleaning and restoration of the outer wall surfaces during 2015. Among this research, GeCo Lab carried out a new systematic and complete laser scanner survey of the whole Baptistery, acquiring data for the more inaccessible parts that were given little attention during other survey campaigns. First of all, the paper analyses recent contributions given by instrumental surveys in advancing knowledge of the building, with references to the cutting-edge techniques and measurement tools used at the time. Then, it describes the new survey campaign, illustrating the approach followed in the planning, data acquisition and data elaboration phases; finally, it gives examples of some

Medication discrepancies are defined as unexplained differences among regimens across different sites of care. The problem of medication discrepancies that occur during the entire care pathway from hospital admission to a local care setting discharge (namely all types of settings dedicated to formal care other than hospitals) has received little attention in the medical literature. The present study aims to (1) determine the prevalence of medication discrepancies that occur during the entire care pathway from hospital admission to local care setting discharge, (2) describe the discrepancy and medication type, and (3) identify potential risk factors for experiencing medication discrepancies in patient care transitions. Evidence from an integrated health care system, such as the Italian one, may explain results from other studies in different healthcare systems. A retrospective longitudinal cohort study of patients admitted from July 2015 to July 2016 to the Giovanni Bosco Hospital serving Turin, Italy and its surrounding territory was performed. Discrepancies were recorded at the following four care transitions: T1: Hospital admission; T2: Hospital discharge; T3: Admission into local care settings; T4: Discharge from local care settings. All evaluations were based on documented regimens and were performed by a team (doctor, nurse and pharmacists). Of 366 included patients, 25.68% had at least one discrepancy. The most frequent type of discrepancy was from medication omission (N = 74; 71.15%). Only discharge from a long-stay care setting (T4) was significantly associated with the onset of discrepancies (p = 0.045). When considering a lack of adequate documentation, not as missing data but as a discrepancy, 43.72% of patients had at least one discrepancy. This study suggests that an integrated health care system, such as Italian system, may influence the prevalence of discrepancies, thus highlighting the need for structured multidisciplinary and, if possible

We analyze and discuss the clinical presentation, the diagnostic procedures and the surgical technique in relation to post-operative complications and results in cervico-mediastinal thyroid masses admitted in Thoracic Surgery Unit of AOU Second University of Naples from 1991 to 2006 and in Thoracic Surgery Unit of AOU "S. Giovanni di Dio & Ruggi D'Aragona" of Salerno over a period of 3 years (2011-2014). We reviewed 97 patients who underwent surgical treatment for cervico-mediastinal goiters. 47 patients (49.2%) had cervico-mediastinal goiter, 40 patients (40%) had mediastino-cervical goiter and 10 patients (10.8%) had mediastinal goiter. 73 cases were prevascular goiters and 24 were retrovascular goiters. We performed total thyroidectomy in 40 patients, subtotal thyroidectomy in 46 patients and in 11 cases the resection of residual goiter. In 75 patients we used only a cervical approach, in 21 patients the cervical incision was combined with median sternotomy and in 1 patient with transverse sternotomy. Three patients (3.1%) died in the postoperative period (2 cardio-respiratory failure and 1 pulmonary embolism). The histologic study revelead 8 (7.7%) carcinomas. Postoperative complications were: dyspnea in 9 cases (10.7%), transient vocal cord paralysis in 6 patients (9.2%), temporary hypoparathyroidism in 9 patients (9.2%) and kidney failure in 1 case (0.9%). The presence of a cervico-mediastinal thyroid mass with or without respiratory distress requires a surgical excision as the only treatment option. Thyroid masses extending to the mediastinum can be excised successfully by cervical incision. Bipolar approach (cervical incision and sternotomy) has an excellent outcome, achieving a safe resection, especially in large thyroid masses extending to the mediastinum with close relations to mediastinal structures and in some limited cases (carcinoma, thyroiditis, retrovascular goiter, ectopic goiter). Postoperative mortality and morbidity is very low, independent of

A Digital Divide has long stood between how NASA and other satellite-derived data are typically archived (time-step arrays or maps) and how hydrology and other point-time series oriented communities prefer to access those data. In essence, the desired method of data access is orthogonal to the way the data are archived. Our approach to bridging the Divide is part of a larger NASA-supported data rods project to enhance access to and use of NASA and other data by the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) Hydrologic Information System (HIS) and the larger hydrology community. Our main objective was to determine a way to reorganize data that is optimal for these communities. Two related objectives were to optimally reorganize data in a way that (1) is operational and fits in and leverages the existing Goddard Earth Sciences Data and Information Services Center (GES DISC) operational environment and (2) addresses the scaling up of data sets available as time series from those archived at the GES DISC to potentially include those from other Earth Observing System Data and Information System (EOSDIS) data archives. Through several prototype efforts and lessons learned, we arrived at a non-database solution that satisfied our objectivesconstraints. We describe, in this presentation, how we implemented the operational production of pre-generated data rods and, considering the tradeoffs between length of time series (or number of time steps), resources needed, and performance, how we implemented the operational production of on-the-fly (virtual) data rods. For the virtual data rods, we leveraged a number of existing resources, including the NASA Giovanni Cache and NetCDF Operators (NCO) and used data cubes processed in parallel. Our current benchmark performance for virtual generation of data rods is about a years worth of time series for hourly data (9,000 time steps) in 90 seconds.

The study of ancient remains is more difficult in urban environments than in an archaeological site, because the ancient town and the modern one superpose to each other and precious testimonies are present just under the current irremovable roads and the buildings. However, modern techniques allows to investigate the past under the present, and allows to retrieve information and possibly create a fruition of the ancient site. IBAM-CNR has been engaged for years in this kind of problems, making use of GPR, ERT and other geophysical techniques [1-3], virtual reality [4] and minimally invasive diagnostics [5] in several towns, in particular in southern Italy and Sicily. The valorization of sites in urban areas require precise projects, founding and clear ideas and agreements about the management of the cultural heritage, because only in this case the work performed will be really exploited and enjoyed by specialists and common people. At the conference, some examples will be shown regarding monuments in the town of Lecce, Italy. References [1] M. Pieraccini, L. Noferini, D. Mecatti, C. Atzeni, R. Persico, F.

Illegal excavations represent one of the main risks which affect the archaeological heritage all over the world. They cause a massive loss of artefacts but also, and above all, a loss of the cultural context, which makes the subsequent interpretation of archaeological remains very difficult. Remote sensing offers a suitable chance to quantify and analyse this phenomenon, especially in those countries, from Southern America to Middle East, where the surveillance on site is not much effective and time consuming or non practicable due to military or political restrictions. In this paper we focus on the use of GeoEye and Google Earth imagery to quantitatively assess looting in Ventarron (Lambayeque, Peru) that is one of most important archaeological sites in Southern America. Multitemporal satellite images acquired for the study area have been processed by using both autocorrelation statistics and unsupervised classification to highlight and extract looting patterns. The mapping of areas affected by looting offered the opportunity to investigate such areas not previously systematically documented.

Over 50% of cancer patients suffer from insomnia, nearly twice the estimated prevalence in the general population. However, this widespread problem has received far less attention compared to cancer pain and fatigue. The aim of this study was to determine whether certain factors can alter the sleep-wake cycle in this patient subgroup and whether altered nyctohemeral sleep rhythms may negatively impact on quality of life. The medical records of 101 patients treated at the Cancer Center, San Giovanni Battista Hospital, Turin, and who had died of cancer in 2007, were reviewed. Extracted from each record were data on: patient age, sex, primary tumor site, presence of pain, concomitant conditions, concomitant medications, type of therapy, chemotherapeutic (CT) scheme, survival, and side effects. The sample was divided into two subgroups defined as inducers or non-inducers, depending on whether the patient had taken medications or not to treat insomnia. Significant differences between the two groups for these variables were tested using statistical analysis. A statistically significant difference between the two groups emerged for anxiety-depression syndromes (P=0.00001), the number of sleeping pills taken in association with a concurrent anxiety-depression syndrome (P=0.01463), and side effects (P=0.0015). There was a statistically significant difference between the inducer and the non-inducer groups for female sex (one-tailed Fisher's exact test; P=0.04170) but the difference was marginal on Fisher's two-tailed test (P=0.06121). No statistically significant differences between the two groups were found for mean age (P=0.61281), median age (P=0.9996), primary tumor site, concomitant conditions (P=0.4205), survival (P=0.5704), presence of pain (P=0.53300) or type of therapy (P=0.6466). Sleep disturbances are a common complaint of cancer patients but have only recently attracted greater attention as the diagnosis of cancer has increased. Sleep disturbances are not an

We have continued to obtain ground-based optical and near-infrared photometry over the last two years using A Novel Dual Imaging CAMera (ANDICAM) on the 1.3m telescope at Cerro-Tololo Inter-American Observatory (CTIO) in Chile. The instrument is operated by the SMARTS consortium. Data were collected almost nightly from 2013 October through 2014 April. Observations were resumed in 2014 September and continued until 2015 April. Each night, four 150s exposures were obtained in each of the three optical bands (VRI) along with 10-15 dithered exposures (30s each) in the near-infrared bands (JHK). All images have a 10.2'*10.2' field of view. The data acquisition and reduction processes are discussed briefly in Appendix A, and a more complete description is given by Windemuth & Herbst 2014 (cat. J/AJ/147/9). The VRIJHK magnitudes from the last two observing seasons have been added to the entire set of CCD data obtained since 1995, which is presented here as Table1. Images of KH 15D were collected with the InfraRed Array Camera (IRAC) on the Spitzer Space Telescope during six observational runs with five separate PI's spanning three distinct epochs since 2004 (2004 Mar 6 and 2004 Oct 08, PI Giovanni Fazio, Program ID=37; 2004 Oct 5-12 and 2005 Oct 21-29, PI Massimo Marengo, Program ID=3441; 2006 Mar 23-27, PI Eric Agol, Program ID=3469; 2008 Nov 1-2, PI Lucas A.

These data were obtained over 28 consecutive days of observation in 2011 December (2011 Dec 3-2012 Jan 1). A final set of observations was obtained on eight nights between 2013 December and 2014 January (2013 Dec 22-2014 Jan 20, PI William Herbst, Program ID=90154, 90098).

Drug use increases with advancing age, and in older patients it is associated with an increase in adverse drug reactions (ADRs). ADRs are a primary cause of morbidity and mortality worldwide. To evaluate the prevalence, clinical characteristics and avoidability of ADR-related hospital admissions in elderly patients. From November 2004 to December 2005, all patients aged >or=65 years consecutively admitted to the Geriatric Unit of the Casa Sollievo della Sofferenza Hospital, San Giovanni Rotondo in Italy, were evaluated for enrolment in the study. ADRs were defined according to the WHO Adverse Reaction Terminology system. Drugs were classified according to Anatomical Therapeutic Chemical classification system. The Naranjo algorithm was used to evaluate the relationship between drug use and the ADR (definite, probable, possible or doubtful) and Hallas criteria were used to evaluate the avoidability of the ADR (definitely avoidable, possibly avoidable or unavoidable). All cases of a suspected ADR were discussed by a team trained in drug safety, including three geriatricians, one clinical pharmacologist and one pharmacist. Only cases of an ADR with an agreement >or=80% were included. Of the 1756 patients observed, 102 (5.8%, 42 males, 60 females, mean age 76.5 +/- 7.4 years, range 65-93 years) showed certain (6.8%) or probable (91.2%) ADR-related hospitalization. Gastrointestinal disorders (48 patients, 47.1%); platelet, bleeding and clotting disorders (20 patients, 19.6%); and cardiovascular disorders (13 patients, 12.7%) were the most frequent ADRs. NSAIDs (23.5%), oral anticoagulants (20.6%), low-dose aspirin (acetylsalicylic acid) [13.7%] and digoxin (12.7%) were the drugs most frequently involved in ADRs. Of the ADRs, 45.1% were defined as definitely avoidable, 31.4% as possibly avoidable, 18.6% as unavoidable and 4.9% as unclassifiable. Of 78 patients with definitely or possibly avoidable ADRs, 17 patients (21.8%) had received an inappropriate prescription, 29

To investigate the serovirological prevalence and clinical features of hepatitis E virus (HEV) infection in end-stage renal failure patients and in the healthy population. HEV infection is a viral disease that can cause sporadic and epidemic hepatitis. Previous studies unexpectedly showed a high prevalence of HEV antibodies in immunosuppressed subjects, including hemodialysis (HD) patients and patients who had undergone kidney transplant. A cohort/case-control study was carried out from January 2012 to August 2013 in two hospitals in southern Italy (Foggia and S. Giovanni Rotondo, Apulia). The seroprevalence of HEV was determined in 801 subjects; 231 HD patients, 120 renal transplant recipients, and 450 health individuals. All HD patients and the recipients of renal transplants were attending the Departments of Nephrology and Dialysis at two hospitals located in Southern Italy, and were included progressively in this study. Serum samples were tested for HEV antibodies (IgG/IgM); in the case of positivity they were confirmed by a Western blot assay and were also tested for HEV-RNA, and the HEV genotypes were determined. A total of 30/801 (3.7%) patients were positive for anti-HEV Ig (IgG and/or IgM) and by Western blot. The healthy population presented with a prevalence of 2.7%, HD patients had a prevalence of 6.0%, and transplant recipients had a prevalence of 3.3%. The overall combined HEV-positive prevalence in the two groups with chronic renal failure was 5.1%. The rates of exposure to HEV (positivity of HEV-IgG/M in the early samples) were lower in the healthy controls, but the difference among the three groups was not statistically significant (P > 0.05). Positivity for anti-HEV/IgM was detected in 4/30 (13.33%) anti-HEV Ig positive individuals, in 2/14 HD patients, in 1/4 transplant individuals, and in 1/12 of the healthy population. The relative risk of being HEV-IgM-positive was significantly higher among transplant recipients compared to the other two

The succession of US and international Earth observing satellites that follow each other, seconds to minutes apart, across the local afternoon equator crossing is called the ATrain. The A-Train consists of the following satellites, in order of equator crossing: OCO, EOS Aqua, CloudSat, CALIPSO, PARASOL, and EOS Aura. Flying in such formation increases the number of observations, validates observations, and enables coordination between science observations, resulting in a more complete virtual science platform (Kelly, 2000). The goal of this project is to create the first ever A-Train virtual data portal/center, the A-Train Data Depot (ATDD), to process, archive, access, visualize, analyze and correlate distributed atmosphere measurements from various A-Train instruments along A-Train tracks. The ATDD will enable the free movement of remotely located A-Train data so that they are combined to create a consolidated vertical view of the Earth's Atmosphere along the A-Train tracks. Once the infrastructure of the ATDD is in place, it will be easily evolved to serve data from all A-Train data measurements: one stop shopping. The innovative approach of analyzing and visualizing atmospheric profiles along the platforms track (i.e., time) will be accommodated by reusing the GSFC Atmospheric Composition Data and Information Services Center (ACDISC) visualization and analysis tool, GIOVANNI, existing data reduction tools, on-line archiving for fast data access, access to remote data without unnecessary data transfers, and data retrieval by users finding data desirable for further study. Initial measurements utilized include CALIPSO lidar backscatter, CloudSat radar reflectivity, clear air relative humidity, water vapor and temperature from AIRS, and cloud properties and aerosols from both MODIS. This will be foilowed by associated measurements from TVILS, =MI, HIRDLS, sad TES. Given the independent nature of instrumentlplatform development, the ATDD project has been met with

The Common Core State Standards (CCSS) provide a consistent, clear understanding of what students are expected to learn, so teachers and parents know what they need to do to help them. In 2010 the standards were designed to be robust and relevant to the real world, reflecting the knowledge and skills that young people need for success in college and careers. In 2013 the Next Generation Science Standards (NGSS) in connection with the CCSS developed revised science standards in performance, prior standards documents listed what students should know or understand, foundations were each performance expectation incorporates all three dimensions from a science or engineering practice, a core disciplinary idea, and a crosscutting concept, and coherence that connects each set of performance expectations lists connections to other ideas within the disciplines of science and engineering. Elizabeth City State University (ECSU) in Elizabeth City, North Carolina has joined with the University of New Hampshire (UNH) in Durham, New Hampshire under the NASA Innovations in Climate Education (NICE) grant to empower faculty of education programs at Minority Serving Institutions (MSIs) to better engage their pre-service teachers in teaching and learning about global climate change through the use of NASA Earth observation sets. Specifically, professors from MSIs received training with Global Positioning Systems (GPS) and GES-DISC Interactive Online Visualization And aNalysis Infrastructure (GIOVANNI) to engage pre-service teachers in facets of climate education. Grambling State University faculty members served as participants of the NICE workshop for 2012 and were encouraged to develop lessons in climate education from information shared at the workshop. A corresponding project that incorporated the CCSS and NGSS at Grambling State University in Grambling, Louisiana was headed by Dr. Loretta Jaggers.

We derive and demonstrate new methods for dewarping images depicted in convex mirrors in artwork and for estimating the three-dimensional shapes of the mirrors themselves. Previous methods were based on the assumption that mirrors were spherical or paraboloidal, an assumption unlikely to hold for hand-blown glass spheres used in early Renaissance art, such as Johannes van Eyck's Portrait of Giovanni (?) Arnolfini and his wife (1434) and Robert Campin's Portrait of St. John the Baptist and Heinrich von Werl (1438). Our methods are more general than such previous methods in that we assume merely that the mirror is radially symmetric and that there are straight lines (or colinear points) in the actual source scene. We express the mirror's shape as a mathematical series and pose the image dewarping task as that of estimating the coefficients in the series expansion. Central to our method is the plumbline principle: that the optimal coefficients are those that dewarp the mirror image so as to straighten lines that correspond to straight lines in the source scene. We solve for these coefficients algebraically through principal component analysis, PCA. Our method relies on a global figure of merit to balance warping errors throughout the image and it thereby reduces a reliance on the somewhat subjective criterion used in earlier methods. Our estimation can be applied to separate image annuli, which is appropriate if the mirror shape is irregular. Once we have found the optimal image dewarping, we compute the mirror shape by solving a differential equation based on the estimated dewarping function. We demonstrate our methods on the Arnolfini mirror and reveal a dewarped image superior to those found in prior work|an image noticeably more rectilinear throughout and having a more coherent geometrical perspective and vanishing points. Moreover, we find the mirror deviated from spherical and paraboloidal shape; this implies that it would have been useless as a concave

the other hand, the applications can collaborate at the same architectural levels, which represent the horizontal interoperability. Both the horizontal and vertical interoperability is accomplished by services and by exchanging data. The calibration procedure requires huge computational resources, which are provided by the Grid infrastructure. On the other hand the scenario development through BASHYT requires a flexible way of interaction with the SWAT model in order to easily change the input model. The large user community of SWAT from the enviroGRIDS consortium or outside may greatly benefit from tools and applications related with the calibration process, scenario development and execution from the enviroGRIDS portal.

, such as HARMOS (official Swiss stratigraphic framework; Morard, 2014, Strasser et al., 2016) is essential to evaluate this type of harmonization system. The current work is establishing composite logs and a stratigraphic catalog where clear stratigraphic framework for the GGB is defined. This will provide a better understanding of the subsurface and a general framework for the new State database. The GEothermie 2020 Program has raised the importance of harmonizing and correlating data in order to understand better the GGB subsurface geology. The future database will be based on a clear and accurate geological and stratigraphic framework where relevant data will be integrated. It will offer a valuable tool to the State of Geneva and external users to find data easily, generate correlations, subsurface models and extract information with specific inquiries. The development of this intelligent and interactive data management system is pivotal to offer an easier and smart management of subsurface resources to the State.

AIM: To investigate the serovirological prevalence and clinical features of hepatitis E virus (HEV) infection in end-stage renal failure patients and in the healthy population. METHODS: HEV infection is a viral disease that can cause sporadic and epidemic hepatitis. Previous studies unexpectedly showed a high prevalence of HEV antibodies in immunosuppressed subjects, including hemodialysis (HD) patients and patients who had undergone kidney transplant. A cohort/case-control study was carried out from January 2012 to August 2013 in two hospitals in southern Italy (Foggia and S. Giovanni Rotondo, Apulia). The seroprevalence of HEV was determined in 801 subjects; 231 HD patients, 120 renal transplant recipients, and 450 health individuals. All HD patients and the recipients of renal transplants were attending the Departments of Nephrology and Dialysis at two hospitals located in Southern Italy, and were included progressively in this study. Serum samples were tested for HEV antibodies (IgG/IgM); in the case of positivity they were confirmed by a Western blot assay and were also tested for HEV-RNA, and the HEV genotypes were determined. RESULTS: A total of 30/801 (3.7%) patients were positive for anti-HEV Ig (IgG and/or IgM) and by Western blot. The healthy population presented with a prevalence of 2.7%, HD patients had a prevalence of 6.0%, and transplant recipients had a prevalence of 3.3%. The overall combined HEV-positive prevalence in the two groups with chronic renal failure was 5.1%. The rates of exposure to HEV (positivity of HEV-IgG/M in the early samples) were lower in the healthy controls, but the difference among the three groups was not statistically significant (P > 0.05). Positivity for anti-HEV/IgM was detected in 4/30 (13.33%) anti-HEV Ig positive individuals, in 2/14 HD patients, in 1/4 transplant individuals, and in 1/12 of the healthy population. The relative risk of being HEV-IgM-positive was significantly higher among transplant recipients

Gobetti 101, Bologna, Italy Abstract Terrestrial plants re-emit around 1-2% of the carbon they fix as isoprene and monoterpenes. These emissions play major roles in the ecological relationships among living organisms and in atmospheric chemistry and climate, and yet their actual quantification at the ecosystem level in different regions is far from being resolved. Phenomenological models are used to estimate the emission rates, but the limited understanding of the function and regulation of these emissions leads to large uncertainties in such estimations. Many measurements have been made at the foliar but few at the ecosystem level, and those that do exist are limited in space and time. We here provide evidence that a simple remote sensing index, the photochemical reflectance index (PRI), which is indicative of light use efficiency (LUE), is a good indirect estimator of foliar isoprenoid emissions and therefore can be used to sense them remotely. These results open

It is a pity, though, that the substantial geographical references and descriptions are not supported by even a single geographical map to guide the reader around Greece and Byzantium. Unfortunately, this publication is pockmarked by just too many typographical errors that were left in place during the copy-editing process. Worse even is the terrible habit of the translator of transposing native first names into modern English look-alikes: John the Grammarian, Marc Eugenicos, John Moisiodax, and the most ridiculous "John Dominique" Cassini (for Giovanni Domenico/Jean-Dominique).

Each year droughts and floods happen around the world and can cause severe property damages and human casualties. Accurate measurement and forecast are important for preparedness and mitigation efforts. Through multi-satellite blended techniques, significant progress has been made over the past decade in satellite-based precipitation product development, such as, products' spatial and temporal resolutions as well as timely availability. These new products are widely used in various research and applications. In particular, the TRMM Multi-satellite Precipitation Analysis (TMPA) products archived and distributed by the NASA Goddard Earth Sciences (GES) Data and Information Services Center (DISC) provide 3-hourly, daily and monthly near-global (50° N - 50° S) precipitation datasets for research and applications. Two versions of TMPA products are available, research (3B42, 3B43, rain gauge adjusted) and near-real-time (3B42RT). At GES DISC, we have developed precipitation data services to support hydrometeorological applications in order to maximize the TRMM mission's societal benefits. In this presentation, we will present examples of utilizing TMPA precipitation products in hydrometeorological applications including: 1) monitoring global floods and droughts; 2) providing data services to support the USDA Crop Explorer; 3) support hurricane monitoring activities and research; and 4) retrospective analog year analyses to improve USDA's world agricultural supply and demand estimates. We will also present precipitation data services that can be used to support hydrometeorological applications including: 1) User friendly TRMM Online Visualization and Analysis System (TOVAS; URL: http://disc2.nascom.nasa.gov/Giovanni/tovas/); 2) Mirador (http://mirador.gsfc.nasa.gov/), a simplified interface for searching, browsing, and ordering Earth science data at GES DISC; 3) Simple Subset Wizard (http://disc.sci.gsfc.nasa.gov/SSW/ ) for data subsetting and format conversion; 4) Data

This study deals with the sedimentary and stratigraphical description of Pleistocene deposits from seven coastal areas of Eivissa (Balearic Islands). Twenty two sedimentary facies have been described involving the succession of eolian, colluvial and edaphic environments. Carbonate sandstones, breccias and silty deposits are the main component of these sequences. Despite the extensive eolian systems outcropping along the coast of Eivissa, there are very few studies performed to chronological framework of these deposits. Luminescence measurements were carried out using an automated RisØ TL/OSL-DA-20 reader in the Luminescence Dating Laboratory of Babes-Bolyai University (Cluj-Napoca, Romania) under low intensity red light. OSL dating of nineteen eolian levels indicate that their deposition took place between the Middle and Late Pleistocene, establishing a paleoclimatic evolution of Eivissa Island since 755 ka to 70 Ka. Eolian activity in the Eivissa Island can be correlated with regression episodes which took place during cold periods associated with different isotopic stages, concretely the MIS 18, 16, 12, 10, 8, 6 and 4. Similar results have been obtained from many sites along the western Mediterranean Sea such as Mallorca (Pomar i Cuerda, 1979; Nielsen et al, 2004; Fornós et al, 2009), Sardinia (Andreucci et al, 2009; Pascucci et al, 2014), Liguria (Pappalardo et al., 2013).

with weakly driven KEEN waves are captured in these simulations. Canonical KEEN waves with ample drive are also treated using these advanced techniques. They will allow the efficient simulation of KEEN waves in multiple dimensions, which will be tackled next, as well as generalizations to Vlasov-Maxwell codes. These are essential for pursuing the impact of KEEN waves in high energy density plasmas and in inertial confinement fusion applications. More generally, one needs a fully-adaptive grid-in-phase-space method which could handle all small vorticlet dynamics whether pealing off or remerging. Such fully adaptive grids would have to be computed sparsely in order to be viable. This two-velocity grid method is a concrete and fruitful step in that direction.

The two invited Technical Seminars were given by Dr. Maurizio Santini (University of Bergamo, Italy) and Prof. Giovanni Tanda (University of Genova, Italy). There were also 13 oral sessions and three poster sessions. This special issue collects the five papers presented in the plenary sessions (keynote lectures and technical seminars) plus 60 papers selected from those presented and discussed during the congress. The UIT 2015 conference has been a useful occasion to stimulate discussion, further the understanding of heat transfer and related phenomena, present the state-of-the-art of some topics, discuss emerging trends and promote collaborations. We hope this issue will maintain and extend some of these features. A special thank you is due to the Organizing and Scientific Committees, to the sponsors and to all the participants.

The Oscillating History in the Exploration of the Red Planet

The oldest, and very vague, map of Mars was drawn in 1659 by Christiaan Huygens, who like Galileo, was pointing his telescopes to nearly anything the sky presented him. In the 1700s, William Herschel, followed by Johann Hieronymus Schroeter, observed Mars extensively and attempted to map its features. In the mid-1800s, Warren De la Rue refined the features on maps of Mars enough to first display, unknowingly, the north and south polar glaciers of Mars. In 1877 Giovanni Virginio Schiaparelli observed a dense network of linear structures on the surface of Mars which he called ``canali'' (Italian: meaning ``channels'', but mistranslated as ``canals''). Schiaparelli also named the ``seas'' and ``continents'' of Mars. With canals and seas, massive speculation began about water and life on Mars, perhaps even a civilization responsible for the canals (and, one might hope, with gondolas and singing gondoliers). Percival Lowell was captivated by the implications of these purported canals and spent much of his life trying to prove the existence of intelligent life on the red planet in the early 1900s. On October 30, 1938, Orson Welles broadcast on radio an adaptation of H.G. Wells' novel ``War of the Worlds''. This caused some listeners to panic. The assumption that Martians were benevolent was severely dented. With NASA's early exploration of Mars - Mariner Missions in the 1960s, and the Viking Missions in the 1970s - Mars was returned to a desolated place, although it now seems possible that the Viking landers were literally inches away from discovering water ice on Mars, finally encountered in abundance over 30 years later by the Phoenix Mission. With the detection of water by the Odyssey Orbiter, geological evidence for ancient water found by the Rovers, the highest resolution images ever taken of Mars by the Mars Reconnaissance Orbiter, and the most recent discoveries by the Phoenix Lander, theories have almost come full circle in returning Mars to a place with water

Boccanelli, A; Spandonaro, F

2000-01-01

In most Italian hospitals, sanitary reform is being applied, while at the same time a new organization of the National Health System is being planned. The director of the medical hospital (head doctor) is becoming more and more involved in management and this aspect has modified his professional attributes. Cardiology is a branch of medicine that, through its scientific preparatory work consisting in debates, management courses, ethics, and production of managerial software, is closer to applying the reform without risking improper administrative aspects. This, obviously, comes about after thoroughly reviewing past work methods and the need to have an administrative organization, which allocates efficient use of manpower and materials, helping to eliminate any sources of inefficiency. The logical procedure foresees an actual analysis in terms of sanitary needs and availability of resources, and so attempting to better balance and harmonize both aspects of the problem. Certainly, the acquisition of theoretical norms and practices, which today are present because of the upsurge in training courses for doctors, is not enough to guarantee the achievement of optimal results. Furthermore, we find that theoretical models need to be validated and adapted to real work situations in the public hospital sector. This paper proposes, therefore, to explain the managerial experiences achieved in actual work situations at the Cardiology Department Unit of the San Giovanni Addolorata Hospital in Rome. In particular, it shows that in order to reach its clinical and economical objectives, it is essential to make available correct informative support for strategic and operational decisions. We can observe that there is a continuing lack of computer support systems being integrated into the present organization of most cardiology units. The use of software distributed to cardiology units from the Associazione Nazionale Medici Cardiologi Ospedalieri (ANMCO) has enabled us to partially

NASA Goddards Giovanni system is used to help map out the spatial distribution of retrieved aerosol optical depths across the latter desert regions. 1-D radiative transfer model constrained by local measurements, including spectral photometry/interferometry and lidar for characterizing the spatiotemporal variability in dust properties and atmospheric conditions, is employed to evaluate the local instantaneous LW DARE of dust both at the surface and at the top of the atmosphere along with heating rate profiles for cloud-free atmospheres. The efficiency in LW DARE and its significance relative to the diurnally averaged SW effects are explored and compared in both studies. Found to be non-negligible, LW DARE is an important component in the study of regional climate variation with important implications for more detailed global assessments.

Candoglia Marble and the "Veneranda Fabbrica del Duomo di Milano": a resource for Global Heritage Stone Designation in the Italian Alps

Alpine marbles have been widely used in the past for celebrated, both indoor and outdoor, applications. Among them, the Candoglia Marble, a worldwide known and appreciated georesource, and its "bastard brother" from the nearby Ornavasso area were and are exploited in the Verbano-Cusio-Ossola quarry basin of Northwestern Italian Alps. They crop out as lenses (up to 30 m in thickness) interlayered within high-grade paragneisses of the Ivrea Zone, a section of deep continental crust that experienced amphibolite- to granulite-facies metamorphism of Palaeozoic age. The Candoglia and Ornavasso Marbles are pinkish to greyish, coarse-grained (> 3 mm), calcitic marbles with frequent, cm-thick, dark-greenish silicate layers containing diopside and tremolite; minor minerals include quartz, epidote, sulphides, Ba-feldspar, barite and, occasionally, phlogopite. First record of quarrying activities in the area arises to the Roman age (Ornavasso quarrying area). Both the Ornavasso and Candoglia Marbles were widely employed in local construction (San Nicola Church and Torre della Guardia at Ornavasso, Madonna di Campagna Church at Verbania, San Giovanni in Montorfano Church), but they became famous thanks to their application for the "Duomo di Milano" since the fourteenth century. At the beginning, the building stones employed for the construction of the Gothic style, Duomo di Milano were quarried in the Ornavasso area, but in a short time, the Candoglia quarry (property of the so-called "Veneranda Fabbrica del Duomo" that incessantly takes care of the Cathedral Church from 1387 A.D.) became the main quarry for the construction and maintenance of the Cathedral. The Candoglia quarry developed during the centuries, from open pit small quarries to a unique underground quarry, characterised by a very peculiar quarrying activities (subvertical bench characterized by strong lateral forces, which have to be contrasted and monitored). The Candoglia Marble was preferred to Carrara marbles

A complete shallow-to-deep transect of sites across these stepped basins, provides a unique opportunity to quantify the amplitude of the Messinian draw-down and to test the hypotheses of a stratified water column and of a diachronous/synchronous onset and end of the salinity crisis. In order to address these persistent open questions, we propose to drill, core and log a shallow-to-deep transect on the Balearic Promontory as part of a daughter proposal (DREAM proposal) of a Multi-phase IODP Drilling Project entitled "Uncovering A Salt Giant" (857-MDP, coord.

Raman spectroscopy in the study of hydrothermal cave minerals: Implications for research on Mars

2013-04-01

Regarding that the ExoMars mission of the ESA, scheduled for launch in 2018 will be equipped with a Raman spectrometer, investigations by Raman spectroscopy on Earth's minerals are essential to interpret data coming from this further mission to Mars. Among terrestrial minerals, cave minerals represent an opportunity to better understand the genesis of Martian minerals and the evolution of Mars itself, in particular by studying minerals formed in hydrothermal conditions, as well as those generated due to hydrothermal alteration of previous materials. The absence of solar radiation, practically constant temperature at daily and seasonal scale and the presence of liquid water are some of the attractions which make caves interesting for Martian research. In the present work, we have studied a great variety of cave minerals from hypogenic/thermal mine-caves like the Giant Geode of Pulpí (south-eastern Spain), the caves of the Naica mine (northern Mexico), the caves of the San Giovanni Mountain (Sardinia, Italy) and Baume Galinière Cave (south-eastern France). Carbonate, sulphate, sulphurs and polymetallic oxyhydroxides are the most common minerals found in these cavities. Among them, it is worth noting the presence of several minerals of the jarosite group and gypsum, since these minerals have been recently discovered on the Mars surface. Both of them are hydrated minerals, which genetic mechanisms are linked to the presence of liquid water. In the case of jarosite minerals, identification of species like argentojarosite and plumbojarosite confers worth to the Raman technique against other methodologies, like XRD by which the characterization of the jarosite group minerals is difficult. As a consequence of the recent discovery of Ca-rich sulphates (probably gypsum) on the surface of Mars, attention has been focused on the terrestrial gypsiferous formations. The gypsum samples from the Giant Geode of Pulpí and the caves of the Naica mine, which are subject of this

The historical research in hospitals organisation began in Europe only after the II World War. In particular, studies regarding the nursing in Italy are very scarce and heavily influenced by the fragmented political and organisational management due to the historical divisions within Italy. All the same, the social and working conditions, at least in the north of Italy, were similar in this respect. The workforce up to the beginning of the 20th Century was equally divided between males and females. The female recruitment took place exclusively from the foundlings left in front of the hospital and raised within the hospital walls. The work was very hard with long working hours, under a total subordination to the religious administrators with miserable wage. These conditions remained unchanged until the second half of the 19th Century when, in central Europe, a change in the reorganisation of hospital management occurred, together with a cultural improvement in the nursing profession. This process of reforms had started in England some decades earlier from the reorganisation of nursing made by Florence Nightingale. After Italian post-unification the healthcare field was involved in the tentative to homologate the vast differences in the hospital organisation within the Italian states which also generated tension, bitterness and many political debates. The particular conditions created in the main hospital of Turin in the second half of the 19th Century, together with the political and social climate at the time and the reopening of debates between Socialist, Liberals and Catholics favoured the reorganizational improvement of the San Giovanni Battista hospital. Under this prospective, the foundation of the nursing school came into being, preceded by the intense control of a behavioral and ethical cleaning of the nurses, in particular the males.

The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) is home of global precipitation product archives, in particular, the Tropical Rainfall Measuring Mission (TRMM) products. TRMM is a joint U.S.-Japan satellite mission to monitor tropical and subtropical (40 S - 40 N) precipitation and to estimate its associated latent heating. The TRMM satellite provides the first detailed and comprehensive dataset on the four dimensional distribution of rainfall and latent heating over vastly undersampled tropical and subtropical oceans and continents. The TRMM satellite was launched on November 27, 1997. TRMM data products are archived at and distributed by GES DISC. The newly released TRMM Version 7 consists of several changes including new parameters, new products, meta data, data structures, etc. For example, hydrometeor profiles in 2A12 now have 28 layers (14 in V6). New parameters have been added to several popular Level-3 products, such as, 3B42, 3B43. Version 2.2 of the Global Precipitation Climatology Project (GPCP) dataset has been added to the TRMM Online Visualization and Analysis System (TOVAS; URL: http://disc2.nascom.nasa.gov/Giovanni/tovas/), allowing online analysis and visualization without downloading data and software. The GPCP dataset extends back to 1979. Version 3 of the Global Precipitation Climatology Centre (GPCC) monitoring product has been updated in TOVAS as well. The product provides global gauge-based monthly rainfall along with number of gauges per grid. The dataset begins in January 1986. To facilitate data and information access and support precipitation research and applications, we have developed a Precipitation Data and Information Services Center (PDISC; URL: http://disc.gsfc.nasa.gov/precipitation). In addition to TRMM, PDISC provides current and past observational precipitation data. Users can access precipitation data archives consisting of both remote sensing and in-situ observations.

(mainly from Earth Observation), current data holdings of SIB-ESS-C have been created in collaboration with a number of partners in previous and ongoing research projects (e.g. SIBERIA-II, SibFORD, IRIS). At the current development stage the SIB-ESS-C system comprises a federated metadata catalogue accessible through the SIB-ESS-C Web Portal or from any OGC-CSW compliant client. Due to full interoperability with other metadata catalogues users of the SIB-ESS-C Web Portal are able to search external metadata repositories. The Web Portal contains also a simple visualization component which will be extended to a comprehensive visualization and analysis tool in the near future. All data products are already accessible as a Web Mapping Service and will be made available as Web Feature and Web Coverage Services soon allowing users to directly incorporate the data into their application. The SIB-ESS-C infrastructure will be further developed as one node in a network of similar systems (e.g. NASA GIOVANNI) in the NEESPI region.

Studying the start of the Maunder Minimum to understand the current situation

NASA Astrophysics Data System (ADS)

Neuhäuser, Ralph; Neuhäuser, Dagmar L.

2016-04-01

To investigate whether we now enter a Maunder-like grand minimum, we have to compare the current situation with the time around the start of the Maunder minimum. Sunspot observations in the 1610s are of particular importance and relevance, because they are shortly before the start of the Maunder Grand Minimum. While the Maunder Minimum it is usually dated from 1645 to 1715, Vaquero & Trigo (2015) argue that what they call the "Extended Maunder Minimum" would have started in 1618 during or around a Schwabe cycle minimum around that time. We have therefore studied the sunspot record of that time in detail. Hoyt & Schatten (1998) compiled for all known telescopic observers a list of their observations; recent solar activity studies for the past four centuries are based on their compilation. In addition to 12 observers listed by Hoyt & Schatten (1998) for the 1610s, we list six more observers with datable spot observations. Furthermore, while Hoyt & Schatten (1998) argue that Simon Marius would have observed from mid 1617 to the end of 1618 almost every day, but would have never seen a spot, we can show with the original reports by Marius that he observed from Aug 1611 to spring 1619 with a lot of sunspot detections. Similar, while Hoyt & Schatten (1998) argue that Giovanni Riccioli would have observed on almost every day in 1618, but would have never seen a spot, he did not report any own observations at all that year, but quoted Argoli for that there were no spots during the periods with comets in 1618. The data base by Hoyt & Schatten (1998) has several more errors in the 1610s, as we show also for the observations by Harriot, Scheiner, Malapert, Saxonius, and Tarde. We also compare drawings from Jungius with the observations by Harriot, Galilei, and Marius. In contrast to what is specified in Hoyt & Schatten (1998), after Harriot, the two Fabricius (father and son), Scheiner and Cysat, Marius and Schmidnerus are among the earliest datable telescopic sunspot

Classification in Astronomy: Past and Present

NASA Astrophysics Data System (ADS)

Feigelson, Eric

2012-03-01

Astronomers have always classified celestial objects. The ancient Greeks distinguished between asteros, the fixed stars, and planetos, the roving stars. The latter were associated with the Gods and, starting with Plato in his dialog Timaeus, provided the first mathematical models of celestial phenomena. Giovanni Hodierna classified nebulous objects, seen with a Galilean refractor telescope in the mid-seventeenth century into three classes: "Luminosae," "Nebulosae," and "Occultae." A century later, Charles Messier compiled a larger list of nebulae, star clusters and galaxies, but did not attempt a classification. Classification of comets was a significant enterprise in the 19th century: Alexander (1850) considered two groups based on orbit sizes, Lardner (1853) proposed three groups of orbits, and Barnard (1891) divided them into two classes based on morphology. Aside from the segmentation of the bright stars into constellations, most stellar classifications were based on colors and spectral properties. During the 1860s, the pioneering spectroscopist Angelo Secchi classified stars into five classes: white, yellow, orange, carbon stars, and emission line stars. After many debates, the stellar spectral sequence was refined by the group at Harvard into the familiar OBAFGKM spectral types, later found to be a sequence on surface temperature (Cannon 1926). The spectral classification is still being extended with recent additions of O2 hot stars (Walborn et al. 2002) and L and T brown dwarfs (Kirkpatrick 2005). Townley (1913) reviews 30 years of variable star classification, emerging with six classes with five subclasses. The modern classification of variable stars has about 80 (sub)classes, and is still under debate (Samus 2009). Shortly after his confirmation that some nebulae are external galaxies, Edwin Hubble (1926) proposed his famous bifurcated classification of galaxy morphologies with three classes: ellipticals, spirals, and irregulars. These classes are still

In-database processing of a large collection of remote sensing data: applications and implementation

Kikhtenko, Vladimir; Mamash, Elena; Chubarov, Dmitri; Voronina, Polina

Large archives of remote sensing data are now available to scientists, yet the need to work with individual satellite scenes or product files constrains studies that span a wide temporal range or spatial extent. The resources (storage capacity, computing power and network bandwidth) required for such studies are often beyond the capabilities of individual geoscientists. This problem has been tackled before in remote sensing research and inspired several information systems. Some of them such as NASA Giovanni [1] and Google Earth Engine have already proved their utility for science. Analysis tasks involving large volumes of numerical data are not unique to Earth Sciences. Recent advances in data science are enabled by the development of in-database processing engines that bring processing closer to storage, use declarative query languages to facilitate parallel scalability and provide high-level abstraction of the whole dataset. We build on the idea of bridging the gap between file archives containing remote sensing data and databases by integrating files into relational database as foreign data sources and performing analytical processing inside the database engine. Thereby higher level query language can efficiently address problems of arbitrary size: from accessing the data associated with a specific pixel or a grid cell to complex aggregation over spatial or temporal extents over a large number of individual data files. This approach was implemented using PostgreSQL for a Siberian regional archive of satellite data products holding hundreds of terabytes of measurements from multiple sensors and missions taken over a decade-long span. While preserving the original storage layout and therefore compatibility with existing applications the in-database processing engine provides a toolkit for provisioning remote sensing data in scientific workflows and applications. The use of SQL - a widely used higher level declarative query language - simplifies interoperability

in a efficient and original way. We propose to investigate these correlations at a daily and intra daily time horizon with a method based on concepts of random frustrated systems. Specifically, a hierarchical organization of the investigated equities is obtained by determining a metric distance between stocks and by investigating the properties of the subdominant ultrametric associated with it [3]. The high-frequency cross-correlation existing between pairs of equities are investigated in a set of 100 stocks traded in US equity markets. The decrease of the cross-correlation between the equity returns observed for diminishing time horizons progressively changes the nature of the hierarchical structure associated to each different time horizon [4]. The nature of the correlation present between pairs of time series of equity returns collected in a portfolio has a strong influence on the variety of the market. We finally discuss the relation between pair correlation and variety of an ensemble return distribution. References [1] Fabrizio Lillo and Rosario N.

since the early XX century. The onsite evaluation of the stone blocks of the façade after more than a century of exposition showed a distinctive surface colour alteration. The formation of a fragile superficial layer of few millimetres thickness with scaling and progressive detachment, has been observed and documented by portable digital microscopy. Samples of the stone have been collected and studied by optical microscopy and scanning electron microscopy on loose fragments, thin sections and polished cross-sections. An interesting and unusualn phenomenon of alteration of the olivine phase has been pointed out [2]. The mineralogical and compositional features were also investigated by means of XRD and FTIR analyses. The results showed that the colour variation can be correlated to the chemical alteration of the stone, which results in the deployment of the magnesium and aluminium content of the most external portion of the material. The study has been conducted in the framework of the diagnostic and monitoring activity for the ongoing conservation work of the façade. [1] Cassinelli, R. (Ed). 1988. Monza anno 1300.

Using a Ground Based radar interferometer during emergency: the case of A3 motorway (Salerno Reggio-Calabria) treated by landslide

An application of Ground Based radar interferometry (GB-InSAR) technique to monitor a landslide threatening infrastructures in emergency conditions is presented. During December 2008 and January 2009 intense rainfalls occurred in Italy, especially in the southern regions. These rain events occurred in the last days of January, worsened the already critical hydrogeological conditions of some areas and triggered many landslides. One of these landslides, named Santa Trada landslide, is located close to a periodical stream called Fiumara di Santa Trada, near Villa San Giovanni municipality (Reggio Calabria, Calabria Region). The volume involved is about 100 000 m3. This estimate represents the case of a collapse of the landslide which destabilize a larger part of the slope, involving other areas delimited by some fractures observed upstream. Nevertheless the landslide does not directly threaten the roadway, its complete collapse would hit the pillars of a motorway viaduct. Through GB-InSAR data it has been possible to obtain an overview of the area affected by movement and to quantify the displacements magnitude. The main benefit of the system was not only limited to the capability of fully characterizing the landslide in spatial terms, it also permitted emergency operators to follow, during the whole campaign, the evolution of the mass movement and to study its cinematic behaviour. This aspect is fundamental to evaluate the volume of the material involved and to assess the temporal evolution of the risk scenario. The GB-InSAR installed at Santa Trada points up toward the landslide from a distance of 250 m. The apparatus produces a synthesized radar image of the observed area every 6 minutes, night and day, with a pixel resolution of about 0.75 m in range and 1.2 m on average in cross range, performing a millimeter accuracy on the final displacement maps. The interferometric analysis of sequences of consecutive images allows the operator to derive the entire line of

The new-found neutron star is the visible counterpart of a pulsating radio source, Pulsar 1055-52. It is a mere 20 kilometres wide. Although the neutron star is very hot, at about a million degrees C, very little of its radiant energy takes the form of visible light. It emits mainly gamma-rays, an extremely energetic form of radiation. By examining it at visible wavelengths, astronomers hope to figure out why Pulsar 1055-52 is the most efficient generator of gamma-rays known so far, anywhere the Universe. The Faint Object Camera found Pulsar 1055-52 in near ultraviolet light at 3400 angstroms, a little shorter in wavelength than the violet light at the extremity of the human visual range. Roberto Mignani, Patrizia Caraveo and Giovanni Bignami of the Istituto di Fisica Cosmica in Milan, Italy, report its optical identification in a forthcoming issue of Astrophysical Journal Letters (1 January 1997). The formal name of the object is PSR 1055-52. Evading the glare of an adjacent star The Italian team had tried since 1988 to spot Pulsar 1055-52 with two of the most powerful ground-based optical telescopes in the Southern Hemisphere. These were the 3.6-metre Telescope and the 3.5-metre New Technology Telescope of the European Southern Observatory at La Silla, Chile. Unfortunately an ordinary star 100,000 times brighter lay in almost the same direction in the sky, separated from the neutron star by only a thousandth of a degree. The Earth's atmosphere defocused the star's light sufficiently to mask the glimmer from Pulsar 1055-52. The astronomers therefore needed an instrument in space. The Faint Object Camera offered the best precision and sensitivity to continue the hunt. Devised by European astronomers to complement the American wide field camera in the Hubble Space Telescope, the Faint Object Camera has a relatively narrow field of view. It intensifies the image of a faint object by repeatedly accelerating electrons from photo-electric films, so as to produce

Enhanced recovery after surgery (ERAS®) is a strategy that seeks to reduce patients’ perioperative stress response, thereby reducing potential complications, decreasing hospital length of stay and enabling patients to return more quickly to their baseline functional status. The concept was introduced in the late 1990s and was first adopted in patients undergoing open colorectal surgery. Since then, the concept of ERAS has been adopted by multiple surgical specialties. The diffusion of video-assisted thoracic surgery lobectomy (VATS-L) sets also the surgical treatment of lung cancer as a new area for ERAS development. In this paper, we present the Italian VATS Group (www.vatsgroup.org) surgical protocol as part of the ERAS clinical pathway belonging to the VATS-L national database. PMID:29629203

columns during a previous work carried out about thirty years ago and whose memory documentation was lost. Both the GPR surveys were carried out by using the K2-RIS IDS system equipped with a high frequency antenna, working at the central frequency of 2GHz. Moreover, the imaging results have been obtained by processing the raw data by means of the end-user friendly software interface designed at the Institute for Electromagnetic Sensing of the Environment - National Research Council of Italy. This interface was some years ago to make possible a simple management of 2D and 3D microwave tomographic approaches based on the Born approximation [4-6].The GPR surveys have confirmed the presence of metallic elements inside few of the investigated columns.

objectives related to the MSC. Among these proposals, one will be fully dedicated to the MSC event. Improved quality of seismic data has allowed important advances in the recognition and understanding of MSC seismic markers (surfaces and depositional units) and lithological and stratigraphical calibrations are now critical. Therefore, the drilling strategy must include multiple sites covering representative locations of both Western and Eastern Mediterranean basins. A series of critical drilling targets were thus identified as follows: - A first set of drilling targets, dedicated to shallow water (< 2500 m water depth) MSC markers, includes the Messinian clastic wedges, the erosion surfaces and the MSC deposits (including thin salt bodies) trapped in small topographic lows observed at various water depths between the shoreline and the abyssal plain. Up to 10 sites, presented in this work, could be drilled with the riserless R/V Joides Resolution, provided the safety conditions are met; - Another critical drilling target is the full recovering of undeformed MSC sequence (including the Tortonian-Messinian and the Messinian-Zanclean boundaries) in the deep water (>2500m) of both the eastern and western Mediterranean basins. This will be possible thanks to R/V Chikyu riser drilling vessel and will be the scope of a second MSC IODP proposal. DREAM Team: A. Giovanni galod@locean-ipsl.upmc.fr, H.

Column NO2-total ozone-stratospheric temperature relationships associated with the Arctic and Antarctic ozone holes

NASA Astrophysics Data System (ADS)

Aheyeva, Viktoryia; Gruzdev, Aleksandr; Grishaev, Mikhail

Data of ground-based measurements of NO2 column contents are analyzed to study winter-spring NO2 anomalies associated with negative anomalies in column ozone and stratospheric temperature. Episodes of significant decrease in column NO2 contents in the winter-spring period of 2011 in the northern hemisphere (NH) were detected at European and Siberian stations of Zvenigorod (55.7°N, Moscow Region) and Tomsk (56.5°N, West Siberia) in the middle latitudes, Harestua (60.2°N), Sodankyla (67.4°N, both in North Europe), and Zhigansk (66.8°N, East Siberia) in the high latitudes, and at the Arctic station of Scoresbysund (70.5°N, Greenland). All the stations, except Tomsk, are a part of the Network of the Detection of Atmospheric Composition Change (NDACC), and the data are accesses at http://ndacc.org. The decrease in NO2 is generally accompanied by total ozone and stratospheric temperature decrease and is shown to be caused by the transport of stratospheric air from the region of the ozone hole observed that season in the Arctic. Overpass total ozone data from Giovanni service and radiosonde data were used for the analysis. Although negative NO2 anomalies due to the transport from the Arctic were also observed in some other years, the anomalies in 2011 reached record magnitudes. A significant positive correlation has been found between variations in NO2 and ozone columns as well as NO2 column and stratospheric temperature during the winter-spring period of 2011, whereas the correlation is much weaker in years without Arctic ozone depletion. The correlation becomes even stronger if only episodes with significant NO2 decrease are considered. For example the correlation coefficients between NO2 and ozone columns deviations are about 0.9 for Zvenigorod and Scoresbysund. Correlation coefficients between variations in column NO2 and total ozone and stratospheric temperature as well as coefficients of regression of NO2 on ozone and temperature in the winter-spring period of

and migration in time domain. The propagation velocity of the electromagnetic waves has been estimated from the diffraction hyperbolas. The processing has been performed making use of the commercial code GPRslice, thanks to which also horizontal slices have been retrieved. As a less conventional aspect, moreover, some ground truthing has been performed on the basis of the horizontal slices by means of a drill with an extension and of an endoscopic survey within the holes made with the drill. This has allowed a more refined interpretation of some of the anomalies, as will be shown at the conference. The noticeable point is that this kind of ground truthing is minimally invasive, much faster than an excavation and of course much cheaper, and so it can be an alternative to it, when possible.

kilometres in diameter that we have found with MARSIS,” said Jeffrey Plaut, MARSIS co-Principal Investigator, from the Jet Propulsion Laboratory, California, “tells us that the underlying crust in the northern lowlands must be very ancient, dating to the Early Noachian epoch (lasting from the planet's birth to about 4 thousand million years ago).” The Early Noachian was an era in which impact cratering was very intense across the Solar System. The results suggest that the crust of the northern lowlands is as old as the oldest exposed southern highlands, also dated to the Noachian epoch, and that the dichotomy between northern and southern hemispheres probably formed very early in the history of Mars. “These results are truly interesting and unprecedented,” added Giovanni Picardi. “MARSIS can contribute to understanding of the geology of Mars through analysis of the surface and subsurface morphology. In addition, from detailed analysis of the instrument’s data, we can obtain valuable information about the composition of the materials.” Note to editors The findings appear in the 14 December 2006 issue of the journal Nature, in the letter headed: “MARSIS radar sounder evidence of buried basins in the northern lowlands of Mars”, by T.R.

close to the neutron star. Geminga’s breathless rotation rate - once every quarter of a second - creates an extraordinary environment in which electrons and positrons, their antimatter counterparts, can be accelerated to extraordinarily high energies. At such energies, they become powerful high-energy gamma-ray producers. Astronomers had assumed that all the electrons would be converted into gamma rays. However, the discovery of the tails proves that some do find escape routes from the maelstrom. “It is astonishing that such energetic electrons succeed in escaping to create these tails,” says Caraveo, “The tail electrons have an energy very near to the maximum energy achievable in the environment of Geminga.” The tails themselves are the bright edges of the three-dimensional shockwave sculpted by Geminga. Such shockwaves are a bit like the wake of a ship travelling across the ocean. Using a computer model, the team has estimated that Geminga is travelling almost directly across our line of sight. Studies of Geminga could not be more important. The majority of known gamma-ray sources in the Universe have yet to be identified with known classes of celestial objects. Some astronomers believe that a sizeable fraction of them may be Geminga-like radio-quiet neutron stars. Certainly, the family of radio-quiet neutron stars, discovered through their X-ray emission, is continuously growing. Currently, about a dozen objects are known but only Geminga has a pair of tails! Note for editors During the search to track down this elusive celestial object, a co-author on the paper, Giovanni Bignami, named Geminga almost 30 years ago. He was Principal Investigator of XMM-Newton's EPIC camera from 1987 to1997 and is now Director of the Centre d'Etude Spatiale des Rayonnements (CESR). Geminga was first glimpsed as a mysterious source of gamma rays, coming from somewhere in the constellation Gemini by NASA's SAS-2 spacecraft in 1973. While searching to pin down its exact location

In Section IV, Dr. Giovanni Barosi reviews our current understanding of the pathophysiology of IMF and, in particular, the contributions of anomalous megakaryocyte proliferation, neoangiogenesis and abnormal CD34(+) stem cell trafficking to disease pathogenesis. The role of newer therapies, such as low-conditioning stem cell transplantation and thalidomide, is discussed in the context of a general treatment strategy for IMF. The results of a Phase II trial of low-dose thalidomide as a single agent in 63 patients with myelofibrosis with meloid metaplasia (MMM) using a dose-escalation design and an overall low dose of the drug (The European Collaboration on MMM) will be presented. Considering only patients who completed 4 weeks of treatment, 31% had a response: this was mostly due to a beneficial effect of thalidomide on patients with transfusion dependent anemia, 39% of whom abolished transfusions, patients with moderate to severe thrombocytopenia, 28% of whom increased their platelet count by more than 50 x 10(9)/L, and patients with the largest splenomegalies, 42% of whom reduced spleen size of more than 2 cm.

Mars Express radar ready to work

, in partnership with NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California. The instrument team is led by Professor Giovanni Picardi. It is the first instrument to actually look below the surface of Mars, using low frequency microwaves reflected by the different layers of matter. Among its primary objectives are the attempt to detect underground water ice and the characterisation of terrains underneath layers of sediment. In addition, MARSIS will conduct large-scale altimetry mapping and provide data on the planet’s ionosphere, as this electrically-charged region of the upper atmosphere reflects radio waves too. Mars Express was launched on 2 June 2003 and reached the Red Planet on Christmas Day that same year. MARSIS was planned to deploy its three antenna booms in April 2004, towards the end of the orbiter’s commissioning phase. Computer simulations pointed to a risk that the booms could lash back and harm the spacecraft and its instruments during deployment. ESA therefore delayed deployment until the boom supplier (JPL) and the spacecraft prime contractor (Astrium, France) together with ESA’s experts had conducted further analyses and simulations of boom behaviour during deployment and the possible impact on the spacecraft. Once the magnitude of the risk involved had been assessed and the relevant mitigation scenarios defined, ESA decided to proceed with releasing the MARSIS antennas in May 2005.

Growing Galaxies Gently

NASA Astrophysics Data System (ADS)

2010-10-01

New observations from ESO's Very Large Telescope have, for the first time, provided direct evidence that young galaxies can grow by sucking in the cool gas around them and using it as fuel for the formation of many new stars. In the first few billion years after the Big Bang the mass of a typical galaxy increased dramatically and understanding why this happened is one of the hottest problems in modern astrophysics. The results appear in the 14 October issue of the journal Nature. The first galaxies formed well before the Universe was one billion years old and were much smaller than the giant systems - including the Milky Way - that we see today. So somehow the average galaxy size has increased as the Universe has evolved. Galaxies often collide and then merge to form larger systems and this process is certainly an important growth mechanism. However, an additional, gentler way has been proposed. A European team of astronomers has used ESO's Very Large Telescope to test this very different idea - that young galaxies can also grow by sucking in cool streams of the hydrogen and helium gas that filled the early Universe and forming new stars from this primitive material. Just as a commercial company can expand either by merging with other companies, or by hiring more staff, young galaxies could perhaps also grow in two different ways - by merging with other galaxies or by accreting material. The team leader, Giovanni Cresci (Osservatorio Astrofisico di Arcetri) says: "The new results from the VLT are the first direct evidence that the accretion of pristine gas really happened and was enough to fuel vigorous star formation and the growth of massive galaxies in the young Universe." The discovery will have a major impact on our understanding of the evolution of the Universe from the Big Bang to the present day. Theories of galaxy formation and evolution may have to be re-written. The group began by selecting three very distant galaxies to see if they could find evidence

Mars Express radar collects first surface data

NASA Astrophysics Data System (ADS)

2005-08-01

This radar started its science operations on 4 July, the same day as its first commissioning phase ended. Due to the late deployment of Marsis, it was decided to split the commissioning, originally planned to last four weeks, into two phases; the second will take place in December. It has thus been possible to begin scientific observations with the instrument earlier than initially planned, while it is still Martian night-time. This is the best environmental condition for subsurface sounding, as in daytime the ionosphere is more ‘energised’ and disturbs the radio signals used for subsurface observations. As from the start of commissioning, the two 20m-long antenna booms have been sending radio signals towards the Martian surface and receiving echoes back. “The commissioning procedure confirmed that the radar is working very well and that it can be operated at full power without interfering with any of the spacecraft systems,” says Roberto Seu, Instrument Manager for Marsis, of University of Rome ‘La Sapienza’, Italy. Marsis is a very complex instrument, capable of operating at different frequency bands. Lower frequencies are best suited to probing the subsurface, the highest frequencies are used to probe shallow subsurface depths, while all frequencies are suited to studying the surface and the upper atmospheric layer of Mars. “During commissioning we worked to test all transmission modes and optimise the radar's performance around Mars,” says Professor Giovanni Picardi, Principal Investigator for Marsis, of University of Rome ‘LaSapienza’. “The result is that since we started the scientific observations in early July, we have been receiving very clean surface echoes back, and first indications about the ionosphere.” The Marsis radar is designed to operate around the orbit ‘pericentre’, when the spacecraft is closer to the planet’s surface. In each orbit, the radar is switched on for 36minutes around this point, spending the middle 26

This years award went to Giovanni Fazio of the Harvard-Smithsonian Center for Astrophysics. Fazio became a leader in gamma ray astronomy before switching mid-career to the study of infrared astronomy, and he gave his award lecture on the latter subject, specifically on the Spitzer Space Telescope, one of the most successful infrared telescopes of all time.Artists rendering of the Spitzer space telescope. [NASA/JPL-Caltech]Spitzer has been operating for more than twelve years, and has resulted in over six thousand papers in refereed journals in that time. The telescope sits in an Earth-trailing orbit around the Sun, and is now farther from the Earth (1.4 AU) than the Earth is from the Sun. Fazio gave the audience a fascinating overview of the science done by Spitzer over more than a decade. One of the most productive areas of research for Spitzer is the study of exoplanets, which hadnt even been discovered when the Spitzer Telescope was first conceived.

, starting from the same 198 patients included in the database, different sub-groups of patients were selected and analyzed in the two papers (they had different echocardiographic characteristics) and, consequently, different factors emerged by the statistical analyses as covariates associated with the different phenotypes of LVSD considered. Importantly, both papers E and J had a very long gestation because all reviewers for the different journals found several and important issues that merited to be addressed: a lot of changes were proposed and much additional information was required, particularly by the reviewers of paper E. Considering this context, it emerges that although paper E was written well before paper J, the two manuscripts were accepted at the same time (we received the letters of acceptance within a couple of weeks). Thus, the uncertainty about the fate of both manuscripts made it very difficult (if not impossible) to cite either of them in the other one and, afterward, we just did not think about this point anymore. Of note, the idea to combine in the analysis longitudinal function came therefore well after the starting process of revision of the paper E and was, in some way inspired by a reviewer's comment. That is why we did not put both findings in the same paper. We think that our explanations provide the broad audience of your journal a perspective of transparency and our respect for the readers' right to understand how the work described in the paper J relates to other work by our research group.

in Belgium for AAVSO to hold its first European meeting in Brussels in July 1990. The meeting proved a huge success, and was followed in 1997 by a second AAVSO European meeting in Sion, Switzerland and a Pan-Pacific meeting in 2003 in Hawaii. Through Janet's leadership, AAVSO reached out to the observers who were already supporting the association with their observations. One of Janet's strong interests was in education. Using a grant from the National Science Foundation, she led efforts to create Hands-On Astrophysics (HOA) based largely on variable stars and AAVSO data. Though it took several years to develop, HOA became the basis for a number of popular teacher workshops and is sure to lead many high school students into careers in science. Janet also helped many future professionals in astronomy, including Karen Meech and Peter Garnavich, and a few in other areas, by providing opportunities for them to work at headquarters during their studies or during an intermission in their formal schooling. Janet was active in, and honored by, other professional and amateur organizations. A member of the American Astronomical Society (AAS), she received the AAS's George van Biesbroeck award in 1993, served on the AAS Annenberg Award Committee (1994-1997) and served as the first chair of the AAS Professional Amateur Cooperation Committee. Also in 1993, the Astronomical League with their Leslie Peltier Award honored Janet for her leadership of the AAVSO and contributions to variable star astronomy. Janet was elected a director of the Astronomical Society of the Pacific (ASP) and served six years in that capacity (1994-2000), co-chairing at least one Pro-Am workshop with the ASP. She was a member of three IAU Commissions over her thirty-five years of membership in that organization. In 1995, Janet was honored by the award of the Royal Astronomical Society's Jackson-Gwilt Medal and was the first recipient of the Giovanni Battista Lacchini Award for collaboration with amateur

Obituary: Philip Morrison, 1915-2005

Trimble, Virginia

2005-12-01

Philip Morrison, who died 22 April 2005 in Cambridge, Massachusetts, was born in Somerville, New Jersey on 7 November 1915 to Moses and Tilly (née Rosenbloom) Morrison. Early childhood polio confined him for extended periods, during which he apparently developed his remarkable skill at speed reading. Speed writing (leading to a bibliography of more than 600 items) came later, and his memory must always have been exceedingly retentive. Morrison went on from the public and private schools of Pittsburgh, Pennsylvania to receive a BS in physics from Carnegie Institute of Technology (now Carnegie Mellon) in 1936. At the University of California, Berkeley, he joined the Young Communist League and later the Communist Party, letting his membership lapse in the early 1940s when work and war came to seem more important. He was officially the student of J. Robert Oppenheimer and worked also with postdocs Robert Serber and Leonard Schiff and with a number of his fellow Oppenheimer students (a spectacular crew, which included Robert Christy, Sidney Dancoff, Bernard Peters [born Pietrkowski], Hartland Snyder, Joseph Weinberg, Dale Corson, Giovanni Rossi Lomanitz, David Bohm, and Eugene Cooper). Following his 1940 PhD, Phil (his preferred signature) taught for a year at San Francisco State and then at University of Illinois (where he replaced Dancoff, who had gone on to a year at Institute for Advanced Study, Princeton). From Illinois, Morrison was recruited to the Metallurgy Lab (uranium project) at the University of Chicago by Christy in 1942. There he worked on the design for the Hanford Reactor, the main source of plutonium for the Trinity and Nagasaki bombs. He seems to have been sensitive to human relationships even in that context and was the author of a "Dear Opje" letter to Oppenheimer pointing out that the lack of cooperation between management and the scientists was getting in the way of the project. Morrison's early research was largely in theoretical nuclear physics

ESA uncovers Geminga's `hot spot'

regions of the star, they found that the ‘colour’ of the X-rays, which corresponds to their energy, changed as Geminga rotated. In particular, they could clearly see a distinct colour change when the hot spot came into view and then disappeared behind the star. This research closes the gap between the X-ray and gamma-ray emission from neutron stars. XMM-Newton has shown that they both can originate through the same physical mechanism, namely the acceleration of charged particles in the magnetosphere of these degenerate stars. "XMM-Newton’s Geminga observation has been particularly fruitful," said Norbert Schartel, ESA’s Project Scientist for XMM-Newton. "Last year, it yielded the discovery of the source tails and now it has found its rotating hot spot." Caraveo is already applying this new technique to other pulsating neutron stars observed by XMM-Newton looking for hot spots. This research represents an important new tool for understanding the physics of neutron stars. Notes for editors The original paper appeared on 16 July 2004, in Science magazine, under the title 'Phase-resolved spectroscopy of Geminga shows rotating hotspot(s)'. Besides P. Caraveo, the author list includes A. De Luca, S. Mereghetti, A. Pellizzoni and G. Bignami. During the search to track down this elusive celestial object, a co-author on the paper, Giovanni Bignami, named it Geminga almost 30 years ago. He was Principal Investigator of XMM-Newton's EPIC camera from 1987 to 1997 and is now Director of the Centre d'Etude Spatiale des Rayonnements (CESR, Toulouse). Geminga was first glimpsed as a mysterious source of gamma rays, coming from somewhere in the constellation Gemini by NASA's SAS-2 spacecraft in 1973. While searching to pin down its exact location and nature, Bignami named it Geminga because it was a ‘Gemini gamma-ray source’. As an astronomer in Milan, Italy, he was also aware that in his native dialect ‘gh'èminga’ means ‘it is not there’, which he found amusing. It

classical atomic-line spectra. The matter is further complicated by the presence of a strong gravitational field near the surface of the pulsar which introduces a wavelength shift of an unknown size. This is the so called `gravitational redshift', a relativistic effect that may be observed in intense gravitational fields. The size of the wavelength shift is proportionate, at least to a first approximation, to the strength of the gravitational field to which the emitting atoms are subjected. But the strength of the pulsar's gravitational field decreases with the altitude above the surface and as we do not know at which altitude the ions that produce the observed `dip' are located, the induced shift is of unknown size. The presence of this feature is an unexpected bonus for the study of the physics of neutron stars. Following a preliminary investigation of the possible causes, the astronomers are now of the opinion that it may have to do with light being absorbed due to the peculiar motion of atoms in the superintense magnetic field around the pulsar [4]. To cast more light on this problem, the group is now planning to obtain spectroscopic observations with an even higher spectral resolution. If not before, this will in any case become possible when the first 8.2-metre VLT Unit Telescope enters into operation in about two years' time. Notes: [1] The group consists of Giovanni Bignami, Patrizia Caraveo, Roberto Mignani and Francesco Nasuti from Istituto di Fisica Cosmica e Tecnologie Relative in Milan, Italy.

[3] Much of this work is due to Lodewijk Woltjer, a Dutch astronomer, who was ESO Director General from 1975 to 1987. [4] However, better data are needed to understand the nature of the absorption. While Iron has some lines in this spectral range, it could as well be cyclotron absorption for Hydrogen.

distant, evolved galaxies and also about the existence of associations of distant galaxies. A first clear example is the concentration of galaxies that appear uniformly yellow in PR Photo 06b/00 , apparently tracing a group of galaxies that was already assembled when the Universe was only 6 billion years old. A confirmation of the distance of a few of these galaxies has already been obtained by means of spectral observations in the framework of an ESO Large Programme , entitled "A Stringent Test on the Formation of Early Type and Massive Galaxies" and carried out by another group of astronomers [2]. A further clear example of a concentration of distant galaxies is seen in the upper right part of PR Photo 06b/00 . The very red colours of several galaxies in this sky area indicate that they are even more distant, "evolved" galaxies, already present when the Universe was only 1/3 of the current age.

observations by the NASA-ESA Hubble Space Telescope, seeing Geminga as a faint visible star. The story will broaden into a hunt for other silent neutron stars like Geminga, using ESA's super-sensitive X-ray astronomy satellite XMM, due to be launched in 1999. Two years later XMM will be followed into orbit by Integral, ESA's successor to COS-B as a gamma-ray astronomy satellite of vastly enhanced performance. Another Hipparcos-Geminga co-author is Giovanni Bignami. He named Geminga in 1976 and has hunted it, with his colleagues in Milan, for more than 20 years. (In the Milanese argot, "ghèminga" means "it's not there" and referred to Geminga's invisibility at radio wavelengths.) Bignami is a principal investigator in the XMM mission, and is director for science in the Agenzia Spatiale Italiana, Rome. "Geminga is a shining example of how multinational collaboration in astronomy pays off," Bignami says. "We in Europe have done very well out of ESA in space astronomy, and also in our collaborations in ground observatories. We have world-class facilities that none of our home countries could offer us on their own. While governments ponder ESA's future role in science they should sense the surge of excitement throughout Europe, as astronomers beat all expectations in using the superb opportunities that come from ESA membership."

PR Photo 09e/02 : The spiral galaxy NGC 5364 was the first object to be observed by VIMOS. This false-colour near-infrared, raw "First Light" photo shows the extensive spiral arms. Technical information about this photo is available below. VIMOS was shipped from Observatoire de Haute-Provence (France) at the end of 2001, and reassembled at Paranal during a first period in January 2002. From mid-February, the instrument was made ready for installation on the VLT MELIPAL telescope; this happened on February 24, 2002. VIMOS saw "First Light" just two days later, on February 26, 2000, cf. PR Photo 09e/02 . During the same night, a number of excellent images were obtained of various objects, demonstrating the fine capabilities of the instrument in the "direct imaging"-mode. The first spectra were successfully taken during the night of March 2 - 3, 2002 . The slit
