  1. Piero della Francesca's Sky in The Dream of Constantine

    NASA Astrophysics Data System (ADS)

    Valerio, V.

    2011-06-01

    The recent restoration of the frescoes by Piero della Francesca in the Church of San Francesco in Arezzo has made to appear on the background of the scene of Constantine's dream a number of stars. They are clearly painted with the intention to illustrate a sort of "natural" sky. In 2001 Anna Maria Maetzke recognized in a group of stars the constellation of the Ursa Minor, but so far no further study has been carried on to find any relation between the painted and the true sky. In this paper I show the existence of more constellations in the fresco, which are hardly detectable due to the mirror representation of the starry sky. Such a mirror image, as the Universe was seen from the outside, has a Greek origin and this kind of representation was introduced in Western Europe not only in celestial globes but also in star maps. This discovery leads to consider that Piero had at his disposal either a globe or a map which he reproduced on the fresco. My hypothesis is that a star map might be supplied to Piero by the astronomer Regiomontanus who was in Italy since 1461 following the Cardinal Bessarion in his journey from Wien to Rome. In 1463, Cardinal Bessarion was named papal legate to Venice and in July of the same year he leaved Rome together with Regiomontanus to reach Ferrara and Venice. The road to Venice crossed Umbria nearby Sansepolcro, Piero's birthplace not far from Arezzo. The trip took more than two weeks due to a stop before crossing the Apennines because the plague in Ferrara. Bessarion and Regiomontanus might have met Piero who was painting the cycle of frescoes in Arezzo and supplied him with a star map. Unfortunately, due to the lack of the horizon and any right line in the scene it is not possible to detect the latitude of the place corresponding to the painted sky.

  8. Maria Goeppert Mayer

    NASA Astrophysics Data System (ADS)

    Moszkowski, Steven A.

    1996-05-01

    The discovery and application of the nuclear shell model, for which Maria Goeppert Mayer received the Nobel Prize in 1963, together with Jensen, was one of the most important developments in nuclear physics. It is not so well known that Maria Goeppert Mayer was an accomplished physicist even from the beginning of her career. She and Joseph Mayer, her husband, coauthored a book on Statistical Mechanics, which was the standard textbook in the subject when I was a student at the University of Chicago. Her discovery of the nuclear shell model was rather unexpected. In fact, from what was known about the nuclear forces at the time, it was expected that the nucleus would behave more like a liquid drop than a quasi-atomic system with independent particle motion. The name ''Magic Numbers'' was coined by Wigner, (who shared the Nobel Prize with Mayer and Jensen for pioneering work in nuclear theory), as he was somewhat skeptical about the shell model, until the evidence for it became convincing. The name stuck, however, and, indeed, it may be quite appropriate as an indication of Maria Mayer's great intuitive powers. The story is not over yet. To this day, the origin of the strong spin-orbit coupling and of nuclear pairing are partially, but not entirely, understood.

  9. Geologic structure of shallow maria. [topography of lunar maria

    NASA Technical Reports Server (NTRS)

    Dehon, R. A.; Waskom, J. A.

    1975-01-01

    Isopach maps and structural contour maps of the eastern mare basins (30 deg N to 30 deg S; 0 deg to 100 deg E), constructed from measurements of partially buried craters, are presented and discussed. The data, which are sufficiently scattered to yield gross thickness variations, are restricted to shallow maria with less than 1500-2000 m of mare basalts. The average thickness of basalt in the irregular maria is between 200 and 400 m. Correlations between surface topography, basalt thickness, and basin floor structure are apparent in most of the basins that were studied. The mare surface is commonly depressed in regions of thick mare basalts; mare ridges are typically located in regions of pronounced thickness changes; and arcuate mare rilles are confined to thin mare basalts. Most surface structures are attributed to shallow stresses developed within the mare basalts during consolidation and volume reduction.

    2014-03-01

    The Maria family is regarded as an old-type (∼3 ± 1 Gyr) asteroid family that has experienced substantial collisional and dynamical evolution in the main belt. It is located near the 3:1 Jupiter mean-motion resonance area that supplies near-Earth asteroids to the inner solar system. We carried out observations of Maria family asteroids during 134 nights from 2008 July to 2013 May and derived synodic rotational periods for 51 objects, including newly obtained periods of 34 asteroids. We found that there is a significant excess of fast and slow rotators in the observed rotation rate distribution. The one-sample Kolmogorov-Smirnov test confirms that the spin rate distribution is not consistent with a Maxwellian at a 92% confidence level. From correlations among rotational periods, amplitudes of light curves, and sizes, we conclude that the rotational properties of Maria family asteroids have been changed considerably by non-gravitational forces such as the YORP effect. Using a light-curve inversion method, we successfully determined the pole orientations for 13 Maria members and found an excess of prograde versus retrograde spins with a ratio (N{sub p} /N{sub r} ) of 3. This implies that the retrograde rotators could have been ejected by the 3:1 resonance into the inner solar system since the formation of the Maria family. We estimate that approximately 37-75 Maria family asteroids larger than 1 km have entered near-Earth space every 100 Myr.

  15. Working with "difficult" patients: an interview with Jorge García Badaracco, by Francesca Viola Borgogno.

    PubMed

    Badaracco, Jorge Garcia

    2010-12-01

    Jorge García Badaracco's pioneering work is well-known in his native Argentina, but not so much elsewhere. Since he was appointed as Director of a service in the Borda Buenos Aires Neuro-Psychiatric Hospital in 1959, García Badaracco started to make use of all available resources to overcome the many problems that the analysis of "difficult patients" (often psychotic) entails. In later years, he developed his ground-breaking "multifamily groups", that is, therapeutic groups that included patients, their relatives, nurses, members of the staff, and that offered the possibility to work simultaneously, in one single therapeutic intervention, on the individual, familiar, and social dimension of the mind. In this interview with García Badaracco, Francesca Viola Borgogno introduces the reader to this distinguished figure, as well as to some of his most original theoretical and clinical concepts, such as "the maddening object", "the pathological and pathogenic interdependence", "the healthy virtuality", and so on.

    2009-01-01

    Great names in science represent an inexhaustible source and richness of inspiration, satisfaction and consolation, a moving and victorious force. Throughout her exemplifying life, Maria Sklodowska remained modest but with a keen sense of humor, of an outstanding style, a mine of knowledge and experience, of innovative ideas and a rich inner life. Full of love, of passion to give and to share, of natural optimism, mixed with a light melancholy, so typical for sages. She vehemently defended the love of scientific research, of the spirit of adventure and entrepreneurship and fought for international culture, for the protection of personality and talent. Maria Sklodowska left her passion to science, her dedication to work including education and training of young people, her passionate adherence to her family, her belief in her friends, her pure and profound humanity and warmth! The paper should be a homage to her, an appreciation of her work over the years, but not less a correspondence, a conversation with her! On the other hand, the present solemn occasion resuscitates the personalities of Maria and Pierre Curie and their work, in particular of Maria Sklodowska in her own native land! In this manner, it truly contributes to her immortality!

  5. Maria Mitchell's Comet - a Challenge Once More?

    NASA Astrophysics Data System (ADS)

    Boyce, P. B.; Graham, A. P.; Strelnitski, V.

    1997-12-01

    This year marks the sesquicentennial of the discovery of a fateful comet by Maria Mitchell (1 October 1847). This was one of the first telescopic comets ever discovered and the first one discovered by a woman. It brought Maria Mitchell the gold medal from the King of Denmark, the first appointment of a woman as professor of Astronomy (at Vassar College) and the fame to be the first (and for ninety years - the only) woman - member of the American Academy of Arts and Sciences. It gave Maria Mitchell an unusually favorable opportunity to struggle for the rights of American women in science. We restore the circumstances of this discovery, and present the results of a modern re-calculation of the orbit of the comet, including its present position in the sky and its ephemeris for the next 50 years. The comet is 32(m) now and will slowly decrease in brightness. Our ability to detect faint objects has improved dramatically over the 150 years since the comet was discovered. By extrapolation, we show that modern technology may catch up with the declining brightness of the comet by the middle of the next century. Another challenge for astronomers!

  6. On the equipotential surface hypothesis of lunar maria floors

    NASA Astrophysics Data System (ADS)

    Arkani-Hamed, Jafar; Konopliv, A. S.; Sjogren, W. L.

    1999-03-01

    The equipotential surface hypothesis suggests that lunar maria floors lie on a surface parallel to the selenoid. This is examined using the spherical harmonic representations of the Clementine topography and Lunar Prospector gravity data. It is demonstrated that the floors of both circular and noncircular maria significantly deviate from an equipotential surface. Deeper circular maria and the deeper part of the noncircular Mare Tranquillitatis have been subsided under larger mass loads in the crust. We calculate the mass beneath the maria to be in excess to the mass required for isostatic compensation of the topography at 60 km depth. A global map of this excess mass shows that the noncircular maria are isostatically compensated, unlike the circular maria. The map also reveals seven new sizable mascons: the three largest are associated with Mendel-Rydberg, Mare Humboldtianum, and Mare Moscoviense.

    Maria Lenk is widely recognized as an exceptional athlete who participated in women's sport from around 1930 until 1950. In 1932, at the age of seventeen, she was the first woman to be included in a Latin American delegation to the Olympic Games. As a swimmer, she still sets world records at the age of eighty-six. This super-champion's sporting achievements and her persistent dedication to the advancement of sport still impress and surprise todays professional swimmers and researchers. Contextualised in the male-dominated society of Brazil during the first half of the twentieth century, this chapter traces the achievement, and rise to international fame, of Maria Lenk. It examines the factors that enabled her to emerge not only as an important figure in sport but also as an icon of female emancipation in Brazilian and Latin American society. The focus is on Lenk's influence on the issues which affected the development of women's sport in Latin America. It also highlights the significance of Lenk's contribution to the changing place of women in Brazilian and South American society.

  10. Finding Basalt Chips from Distant Maria

    2006-04-01

    The Apollo 16 landing site is in the lunar highlands, over 200 kilometers away from the nearest maria. Nevertheless, the Apollo 16 regolith contains a small percentage (<1%) of tiny fragments thrown to the site from distant maria. Ryan Zeigler, his colleagues at Washington University in St. Louis: Randy Korotev, Brad Jolliff, and the late Larry Haskin, and Jeffrey Gillis-Davis (University of Hawaii) made a detailed study of the chemical composition and mineralogy of fragments (only 2-4 millimeters across) of mare basalts. The basalts vary in composition, but are similar to other types identified previously. The team matched the compositions of the fragments to compositions of mare surfaces in the Apollo 16 region using remote sensing data from the Clementine mission. This blending of cosmochemical and remote sensing analyses allowed them to make educated guesses about where each of the basalt fragments may have originated. We now have a fuller understanding of the range of compositions of mare basalts and, because basalts record a wealth of information about planetary interiors, this research enlightens us about the diversity of rock compositions in the lunar mantle.

  12. Lunar maria - result of mantle plume activity?

    NASA Astrophysics Data System (ADS)

    Sharkov, E.

    It is generally accepted that lunar maria are the result of catastrophic impact events. However, comparative studying of the Earth's and the Moon's tectonomagmatic evolution could evidence about another way of these specific structures origin. Such studies showed that the both planetary bodies evolved on the close scenario: their geological development began after solidification of global magmatic oceans which led to appearance of their primordial crusts: granitic on the Earth and anorthositic - on the Moon. The further evolution of the both bodies occurred in two stages. For their first stages, lasted ˜2.5 mlrd. years on the Earth and ˜1.5 mlrd. years on the Moon, were typical melts, generated in depleted mantle (Bogatikov et al., 2000). However, at the boundary 2.2-2.0 Ga ago on the Earth and 3.9-3.8 Ga on the Moon another type of magmas appeared: geochemical enriched Fe-Ti picrites and basalts, characteristic for the terrestrial Phanerozoic plume-related situations, and basaltic mare magmatism with high-Ti varieties on the Moon. It suggests that evolution of the Earth's magmatism was linked with ascending of mantle plumes (superplumes) of two generation: (1) generated in the mantle, depleted during solidification of magmatic ocean and Archean magmatic activity, and (2) generated at the core-mantle boundary (CMB). The latter were enriched in the mantle fluid components (Fe, Ti, alkalies, etc); this lighter material could ascend to shallower depths, leading to change of tectonic processes, in particular, to appearance of plate tectonics as the major type of tectonomagmatic activity till now (Bogatikov et al., 2000). By analogy to the Earth, magmatism of the Moon was also linked with ascending of mantle plumes: (1) generated in the depleted mantle (magnesian suite) and (2) generated at the lunar CMB with liquid at that time metallic core (mare basalt and picrites with high-Ti varieties). Like on the Earth, these plumes were lighter than the older plumes, and

  14. Lunar Maria and circular basins-a review

    USGS Publications Warehouse

    Stuart-Alexander, D. E.; Howard, K.A.

    1970-01-01

    Lunar Orbiter data make it possible to examine the distribution and relations of maria and large circular basins over the entire Moon. The restricted distribution and age of the maria are in marked contrast to the apparently random distribution in time and place of the circular basins, some of which contain mare fillings. The circular basins are believed to be impact scars, and the maria to be volcanic fills which in each case are younger than the structures they fill. Twenty-nine circular basins 300 km wide or wider are recognized. They are placed in an age sequence because successive stages of degradation can be recognized from the fresh Orientale basin to the almost obliterated basin containing Mare Australe. The maria were emplaced during a short span of lunar history, although some light plains of the highlands may be older maria lightened through age. The present maria are topographically low, tend to be associated with large circular basins, and lie in a crude global belt of regional concentrations; 94% are on the hemisphere facing the Earth. Possible explanations offered for these patterns of mare distribution include impact-induced volcanism, volcanic extrusion to a hydrostatic level, isostatic compensation, lateral heterogeneity in the lunar interior, subcrustal convection, and volcanism due to disruption by Earth's gravity. ?? 1970.

  15. Maria Goeppert Mayer and the Nobel Prize

    NASA Astrophysics Data System (ADS)

    Johnson, Karen E.

    2013-04-01

    When Maria Goeppert Mayer was awarded the Nobel Prize in Physics in 1963, she was only the second woman to receive that award and there have been no additional female physics laureates since. Mayer was uniquely prepared to carry out her prize-winning work on the nuclear shell model. Furthermore, she worked with some of the most well-known figures in mid-twentieth century physics, and her award came at a time when American science was in ascendance. Why, then, is her name so little known beyond the physics community? There are several possible answers to this question, ranging from the personal (her modest reaction to public acclaim) and the scientific (the mathematically abstract nature of her prize-winning work), to the national (the nature of the issues commanding public attention in the 1960s). In this talk I will present an overview of the circumstances that enabled Mayer to make exceptional contributions to nuclear physics, and then examine some of the possible reasons why her exceptional status is not more widely known.

    2001-01-01

    The empress and queen Maria Theresa Habsburg-Lorraine (May 13th, 1917-November 29th, 1780) bore sixteen children in the marriage with the emperor Franz I Stepha and was famous as "mother-in-law of Europe". Her brother Leopold died immediately after he was born, her sister Amalia died in the cradle and Maria Ana died of perinatal complications at the birth of a dead infant in 1744. The famous hereditary facial dysmorphia of the "Hasburg jawe" wasn't noticed in Maria Theresa's surviving children. In October of 1738, after giving birth to her daughter Ana, a manual lysis of the placenta was performed due to the retained placenta and postpartal bleeding. In 1741 her daughter Carolina died, and in 1767 her daughter Josepha died of small pox. Her daughter Elizabeth remained deformed by the pock marks, and Maria Christina got a puerperal sepsis, but surprisingly, didn't die. Maria Antoinette ended under a guillotine in France, along with her husband Luis XVI. Maria Theresa's father, Karl VI died of the cholecystopankreatitis and peritonitis, and her husband and co-ruler most probably died of acute coronary incident in August 18th, 1765. After her husband's death she started suffering from depression with steady necrophile obsessions. Maria Theresa suffered from a chronical obstructional pulmonary disease (asthma), rehumatic syndromes, hypertension and anxiodepressive syndromes. In 1767 she had small pox. In November 11th 1780 she caught a cold which grew into a pneumonia with high fever. She died of cardiopulmonal dedompensation preceded by pneumonia and asthma.

  17. Ages of the lunar nearside light plains and maria

    NASA Technical Reports Server (NTRS)

    Boyce, J. M.; Dial, A. L.; Soderblom, L. A.

    1974-01-01

    An extension of a previous work on relative age mapping for the lunar nearside is presented. The ages were determined from Apollo (Hasselblad, metric, and panoramic) and Lunar Orbiter photographs; three major subdivisions were observed: maria and two older light plains units. The plains units center around 3.8 b.y. and 4.0 b.y., respectively. Ages of maria decrease westward. The oldest maria is 3.7 b.y.; it comprises Mare Tranquillitatis and two small areas in southeastern Mare Imbrium. Oceanus Procellarum, southwestern Mare Imbrium, northern Mare Humorum, and northwestern Mare Serenitatis contain the youngest maria; the youngest of these formed about 1.7 b.y. ago. Emplacement of all three subdivisions occurred over a 2.3 b.y. interval. The three-stage model of mare emplacement proposed by Soderblom (1970a) is confirmed. Thus the sequence is (1) high-Ti basalts in the eastern hemisphere, (2) low-Ti basalts filling circular ring-maria, and (3) high-Ti basalts in the western hemisphere.

    Maria Skłodowska Curie left us a great legacy. Her discovery of polonium and radium was incomparably greater than the mere discovery of new elements. Its significance lay in the discovery of a new form of matter, namely radioactive one, but also in her unveiling of the internal property of its atoms. Subsequently emitted radiation went on to play the role of a "natural accelerator" for both scientific research and in medical radiotherapy. It was thanks to these discoveries that the field of nuclear physics arose just a few decades later. As importantly the work of Maria Curie Skłodowska during the Great War demonstrated how important pure scientific discovery can be for society and its welfare.

    2013-04-01

    Maria Goeppert Mayer received the Nobel Prize in Physics in 1963 for her work on the nuclear shell model. I knew her in my teens as a close ``friend of the family.'' The Mayers lived a few blocks away in Leonia, New Jersey from 1939 to 1945, across the street in Chicago from 1945 to 1958 and about one mile away in La Jolla, CA from 1960 till her death. Maria held primarily ``vol'' (voluntary) positions during this period, although in Chicago she was half time at Argonne National Laboratory as a Senior Physicist. She joined the University of California at San Diego as a professor in 1960, her first full-time academic position. I will discuss her positive impact on a teenager seriously considering becoming a physicist. I will also discuss briefly the impact of her work on our understanding of the structure of nuclei. Maria Mayer was creative, well educated, with a supportive father and husband, but she was foreign , received her Ph D at the time of the Great Depression, and was one of the few women trained in physics. Her unusual career and her great success is due to her love of physics and her ability as a theoretical physicist.

    The core of the MARIA high flux multipurpose research reactor is highly heterogeneous. It consists of beryllium blocks arranged in 6 x 8 matrix, tubular fuel assemblies, control rods and irradiation channels. The reflector is also heterogeneous and consists of graphite blocks clad with aluminum. Its structure is perturbed by the experimental beam tubes. This paper presents methods and codes used to calculate the MARIA reactor neutronics characteristics and experience gained thus far at IAE and ANL. At ANL the methods of MARIA calculations were developed in connection with the RERTR program. At IAE the package of programs was developed to help its operator in optimization of fuel utilization.

  13. Mesoarchean sanukitoid rocks of the Rio Maria Granite-Greenstone Terrane, Amazonian craton, Brazil

    2009-02-01

    The Archean sanukitoid Rio Maria Granodiorite yielded zircon ages of ˜2.87 Ga and is exposed in large domains of the Rio Maria Granite-Greenstone Terrane, southeastern Amazonian craton. It is intrusive in the greenstone belts of the Andorinhas Supergroup, in the Arco Verde Tonalite and Caracol Tonalitic Complex (older TTGs). Archean potassic leucogranites, younger TTGs and the Paleoproterozoic granites of Jamon Suite are intrusive in the Rio Maria Granodiorite. The more abundant rocks of the Rio Maria Granodiorite have granodioritic composition and display medium to coarse even-grained textures. These rocks show generally a gray color with greenish shades due to strongly saussuritized plagioclase, and weak WNW-ESE striking foliation. The significant geochemical contrasts between the occurrences of Rio Maria Granodiorite in different areas suggest that this unit corresponds in fact to a granodioritic suite of rocks derived from similar but distinct magmas. Mingling processes involving the Rio Maria Granodiorite and similar mafic to intermediate magmas are able to explain the constant occurrence of mafic enclaves in the granodiorite. The associated intermediate rocks occur mainly near Bannach, where mostly quartz diorite and quartz monzodiorite are exposed. The dominant rocks are mesocratic, dark-green rocks, with fine to coarse even-grained texture. The Rio Maria Granodiorite and associated intermediate rocks show similar textural and mineralogical aspects. They follow the calc-alkaline series trend in some diagrams. However, they have high-Mg#, Cr, and Ni conjugate with high contents of large ion lithophile elements (LILEs), typical of sanukitoids series. The patterns of rare earth elements of different rocks are similar, with pronounced enrichment in light rare earth elements (LREEs) and strong to moderate fractionation of heavy rare earth elements (HREEs). Field aspects and petrographic and geochemical characteristics denote that the granodiorites and

    Materials Maria Maya (MMM) is a Guatemalan organization which has dedicated itself to making health education more relevant to the rural Mayans who constitute the majority of Guatemala's population. The administration and direction of the project is in the hands of a team of qualified Mayan men and women. Funding is primarily through various charitable international organizations. The content of preexisting health education programs, strongly influenced by the dominant "ladino" Spanish speaking culture was found to be inappropriate to the goal of this program. MMM set about to formulate a new teaching format which would draw upon, rather than trample over, established cultural practices and life styles. By a process of trial and error, involving small scale field tests, a new program format was developed. By questioning local women about perceived priority areas, through the study of morbidity and mortality data, decisions were made as to topics to be covered. Investigators, authors, and artists worked together to form a "materials package" which was then subject to pretesting. Out of this effort, MMM has been able to come up with a method to encourage more effective participative teaching through the use of education materials.

  15. Electrical conductivity anomalies associated with circular lunar maria

    NASA Technical Reports Server (NTRS)

    Dyal, P.; Daily, W. D.

    1979-01-01

    A strong anisotropy is observed in magnetic field fluctuations measured by the Lunokhod 2 magnetometer located on the eastern edge of Mare Serenitatis. This anisotropy can be explained by a regional anomaly in the subsurface electrical conductivity distribution associated with the mare similar to the proposed conductivity anomaly associated with Mare Imbrium. The Serenitatis magnetic field anisotropy is compared to the field fluctuation measured by the Apollo 16 magnetometer 1100 km to the south, and this comparison indicates that the subsurface conductivity distribution can be modeled by a nonconducting layer in the lunar lithosphere which is 150 km thick beneath the highlands and 300 km thick beneath Serenitatis. The decrease in electrical conductivity of the upper mantle beneath the mare may result from lower temperatures due to transport of thermal energy and radioactive heat sources to the surface during mare flooding. This proposed anomaly, along with that proposed for Mare Imbrium, strengthens the possibility of regional anomalies in electrical conductivity associated with all circular lunar maria.

    When the Maria Mitchell Observatory was erected in 1908 to house the 5-inch telescope that had been given Maria Mitchell in 1859, Mrs. Lydia Hinchman, niece of Maria and the principal co-founder of the Maria Mitchell Association, wanted the Observatory to specialize in research while not neglecting public relations entirely. She contacted Professor E. C. Pickering, Director of Harvard College Observatory, for advice. He recommended installing a photographic telescope and having the astronomer specialize in observations of variable asteroids, Eros in particular. Margaret Harwood, one of his assistants at Harvard, was chosen to head the Maria Mitchell Observatory, a post she held for 45 years. Besides lesser contributions, she published a catalogue of 74 asteroids known to have variable brightness. She discovered DF Cygni, an unusual type of variable star with multiple periods, and analyzed its variation on Harvard and Nantucket plates spanning over 50 years. Her final masterpiece was an analysis of 419 variable stars in the Scutum region of the Milky Way, the majority of the variables having been discovered by her High School assistant John Heath. The second Director, Dorrit Hoffleit, instituted a new project, Summer Research Participation on Variable Stars by College Undergraduates, especially women. This project was continued by her successor, Emilia Belserene. Nearly 200 college undergraduates participated in these programs. The fourth Director, Eileen Friel concentrated on both observational and theoretical researches on star clusters, her student contributing few papers on variable stars. The current Direcor, Vladimir Strelnitski, again enthusiasticlly specializes on modern problems of variable stars.

    New visible and near-infrared multispectral images of the Moon obtained by the Galileo solid-state imaging system, along with lunar orbiter images (for crater counts), and spectral mixing analyses were used to characterize western limb and eastern farside maria and determine compositional and age relationships in selected regions. Results indicate that (1) western limb mare deposits have less variability in titanium content (<2-7 wt% TiO2) and age (2.79-3.86 Ga) than areally extensive maria on the nearside; (2) areally extensive basin-filling maria generally have higher titanium contents than smaller, crater-filling mare patches and ponds; (3) ancient maria covered by highland material (cryptomaria) may be present in the Mendel-Rydberg and South Pole-Aitken basins; and (4) maria with compositional and age variations occur in the Grimaldi, Crüger, Mendel-Rydberg, and Apollo regions. No extensive high-titanium (>6 wt% TiO2) mare basalts were observed on the western limb and farside, which may reflect the inability of such denser magmas to penetrate the thicker farside crust.

  18. Ages of flow units in the lunar nearside maria based on Lunar Orbiter IV photographs

    1976-01-01

    A map dividing the lunar nearside maria into six units each of uniform age was compiled from Lunar Orbiter IV photographs. Relative ages were determined using a crater morphology technique. Relative ages were then converted to absolute ages by comparison to a curve calibrated from Apollo and Luna sample data; three of the six units, including the two youngest (about 3.1 and 2.6 b.y. old), were not sampled by Apollo or Luna. Vast regions in the western maria are covered by these young flows. The old flows (about 3.75 b.y. in age) are found to occur mostly in the eastern maria. A comparison of the age units derived from these data with those units derived from other remote-sensing data provide good agreement in the location of unit boundaries. These data also indicate that the emplacement history of mare basalt types is more complex than was earlier thought.

Enhancements are seen at the edges of Mare Fecunditatis, Mare Crisium, Mare Smythii, Mare Tranquillitatis, Mare Nubium, Mare Cognitum, and Oceanus Procellarum. The observation is indicative of the transient emission of radon gas from the perimeters of lunar maria.

    The processes by which craters disappear from the lunar surface have been of principal concern since the first high-resolution pictures of the lunar maria were returned by Ranger VII. Those pictures revealed that craters smaller than a few hundred meters on the lunar maria vary morphologically from sharp and pristine features to shallow, highly subdued depressions. The constancy of the population density of these smaller craters (with diameters of less than 1000 m) was predicted by Moore (ref. 25-40) and Shoemaker (ref. 25-41), who concluded that these craters were in a steady-state condition.

    Lupinus mariae-josephae is a recently discovered endemism that is only found in alkaline-limed soils, a unique habitat for lupines, from a small area in Valencia region (Spain). In these soils, L. mariae-josephae grows in just a few defined patches, and previous conservation efforts directed towards controlled plant reproduction have been unsuccessful. We have previously shown that L. mariae-josephae plants establish a specific root nodule symbiosis with bradyrhizobia present in those soils, and we reasoned that the paucity of these bacteria in soils might contribute to the lack of success in reproducing plants for conservation purposes. Greenhouse experiments using L. mariae-josephae trap-plants showed the absence or near absence of L. mariae-josephae-nodulating bacteria in “terra rossa” soils of Valencia outside of L. mariae-josephae plant patches, and in other “terra rossa” or alkaline red soils of the Iberian Peninsula and Balearic Islands outside of the Valencia L. mariae-josephae endemism region. Among the bradyrhizobia able to establish an efficient symbiosis with L. mariae-josephae plants, two strains, LmjC and LmjM3 were selected as inoculum for seed coating. Two planting experiments were carried out in consecutive years under natural conditions in areas with edapho-climatic characteristics identical to those sustaining natural L. mariae-josephae populations, and successful reproduction of the plant was achieved. Interestingly, the successful reproductive cycle was absolutely dependent on seedling inoculation with effective bradyrhizobia, and optimal performance was observed in plants inoculated with LmjC, a strain that had previously shown the most efficient behavior under controlled conditions. Our results define conditions for L. mariae-josephae conservation and for extension to alkaline-limed soil habitats, where no other known lupine can thrive. PMID:25019379

  6. Ages of flow units in the far eastern maria and implications for basin-filling history

    NASA Technical Reports Server (NTRS)

    Boyce, J. M.; Jonnson, D. A.

    1978-01-01

    The spatial distribution of major units of uniform relative age exposed in the far eastern maria and Mare Humorum was determined using a crater density mapping technique. Correlation of crater densities and radiometric ages of Apollo and Luna landing sites provided estimates of the absolute ages for the units. The combination of such data with relative age data from previous crater morphology studies produced a complete map of the distribution of major age units in the lunar near-side maria. The map shows that there are young (2.5 + or - 0.5 billion years old) mare basalts in the eastern maria, although most young flows occur in the western maria. The vents for the young flows generally are found along the edges of basins. Because old mare units (greater than 3.5 billion years old) are also commonly found around the edges of the basins, it is suggested that the basins were subsiding during filling, probably as a result of isostatic compensation due to the weight of the lava.

    The MARIA reactor is a high-flux multipurpose research reactor which is water-cooled and moderated with both beryllium and water. Standard HEU (80% {sup 235}U)fuel assemblies consist of six concentric fuel tubes of a U-Al alloy clad in aluminum. Although the inventory of HEU (80%) fuel is nearly exhausted, a supply of highly-loaded 36%-enriched fuel assemblies is available at the reactor site. Neutronic equilibrium studies have been made to determine the relative performance of fuels with enrichments of 80%, 36% and 19.7%. These studies indicate that LEU (19.7%) densities of about 2.5 gU/cm{sup 3} and 3.8 gU/cm{sup 3} are required to match the performance of the MARIA reactor with 80%-enriched and with 36%-enriched fuels, respectively.

    The essay shows how two royalist recipe books- The queens closet opened (1655) and The court & kitchin (sic) of Elizabeth (1664)- fashioned Henrietta Maria (1609-69) and Elizabeth Cromwell (1598-1665) as very different housewives to the English nation. By portraying the much-disliked French Catholic Henrietta Maria as engaged in English domestic practices, The queens closet opened implicitly responded to the scandalous private revelations of The kings cabinet opened (1645); while, in contrast, the satiric cookery book attributed to Elizabeth Cromwell stigmatized her as both a country bumpkin and a foreigner. Yet the cookery books also had unintended republicanizing effects, as consumers appropriated the contents of the queen's closet for their own cabinets and kitchens.

    The overwintering biology of Aedes (Ochlerotatus) mariae (one of the sibling species of the mariae complex) was studied in populations from the Tyrrhenian coast of Central Italy (Sperlonga and Formia). Ae. mariae has in this zone several generations per year and its larvae are commonly found from March to October exclusively in rock pools along the coast. Field and laboratory observations show in these populations an embryonic winter diapause induced by short-day photoperiods (9-12 hours). The photoperiod acts primarily on the parental females during their preimaginal life. The expression of diapause is influenced by temperatures and photoperiods experienced by the embryos. Full embryonic diapause is observed when the eggs are incubated at relatively low temperatures (less than 16 degrees C) and at short photoperiods. Short-day photoperiods also induce a remarkable change in the oviposition behavior of Ae. mariae. Laboratory observations show that the adult females readily oviposit on water surfaces when originating from larvae reared at long-day photoperiod while they are very reclutant to oviposit in the same situation when reared at short day photoperiod. Choice experiments involving four alternative oviposition sites (see Plate 1) demonstrate a preference for outside free water in long-day mosquitoes and for inside moist surfaces in short-day mosquitoes. The behavioral difference persists in successive gonotrophic cycles and it is not apparently affected by the photoperiod acting on the adult females. The above evidence together with recovery of overwintering eggs in holes and crevices of rock pools suggest that the shift in oviposition site shown in the laboratory reflects a similar shift occurring in nature. Such photoperiodically induced change in oviposition behavior seems to have an important adaptive significance in providing more constant microclimates to the diapausing eggs and in protecting them from the mechanical action of winter storms.

Today Jakob is mainly remembered by neurologists for the spongiform encephalopathy with progressive dementia and spasticity that he, and Kiel neuropathologist Hans Gerhard Creutzfeldt (1885-1964), described independently. However, Jakob has left additional contributions to neuroanatomy, neuropathology and neuropsychiatry in the form of original articles and valuable monographs.

    Two prominent subsurface structural features of the Central Offshore Santa Maria Basin are the Hosgri fault system and the associated anticlinal fold trend. Exploratory drilling and 3D seismic mapping have delineated a series of oil and gas fields along this trend which underlie four federal units and one non-unitized lease. The units are named after local geography and are called the Lion Rock, Point Sal, Purisima Point and Santa Maria Units. The individual lease, OCS P-0409, overlies the San Miguel field. The Hosgri fault system trends northwest-southeast and effectively forms the eastern boundary of the oil and gas province. Lying semi-parallel with the fault are several anticlinal culminations which have trapped large volumes of oil and gas in the fractured Montery Formation. The Monterey is both source and reservoir rock, averaging 300 meters n thickness throughout the Central Basin. Development of the Monterey Formation as a reservoir rock was through diagensis and tectonism with resulting porosities-from 15 to 20% and permeability up to one Darcy. These parameters coupled with a high geothermal gradient facilitate the inflow rates of the viscous Monterey oil. Some 24 exploration and delineation wells have been drilled in this area and tested at rates ranging from a few hundred to several thousand barrels per day. Estimated oil reserves in the Central Offshore Santa Maria Basin total approximately 1 billion barrels.

Centrolenella puyoensis is distinguished by its moderately large size, a snout truncate in dorsal view and rounded in profile, a color pattern in preservative of purplish-gray with large cream spots, a tympanum that is three-fourths exposed, and intricate anal ornamentation. Both new species are closely related to the Peruvian C. mariae, and together the three species form the C. mariae group, definable on a number of shared, derived characters. A hypothesis of relationships within the mariae group is presented, postulating puyoensis as the most primitive and azulae as the most derived of the trio.

    Due to the lack of studies about neurocysticercosis in the South of Brazil, an investigation was conducted to determine the percentage of suspected cases of neurocysticercosis in computed tomography diagnoses in Santa Maria, RS, from January 1997 to December 1998. Of 6300 computed tomographies (CT) of the skull performed at the private Hospital de Caridade Astrogildo de Azevedo, 80, i.e., 1.27% were suspected of neurocysticercosis. Fifty were women (62.5%) and 30 were men (37.5%). The most frequent radiological manifestation indicating neurocysticercosis was the presence of calcifications (isolated or associated), with a 95% rate (76 cases), while the presence of hypodense lesions reached a 5% rate (4 cases). After routine analysis, each CT was evaluated again and the suspected cases were confirmed. The percentage of suspected cases of neurocysticercosis detected by CT in the present study carried out in Santa Maria was considered low (1.27%). This can be explained by the fact that tomography is not accessible to the economically underprivileged population of Santa Maria. We hope that the present study can alert the population and the professionals to the fact that neurocysticercosis is a more frequent disease than indicated by the few diagnoses made.

    Chert is a common component of the Monterey Formation in many outer Neogene basins. Successful recovery of diatoms from dolomite beds and concretions, which are sufficiently abundant in chert-bearing sections, makes diatom biostratigraphic analyses possible in several poorly chronicled Neogene basins. At Ano Nuevo in the Outer Santa Cruz basin, where the section consists mainly of porcelanite and chert, diatom biostratigraphy yields an age duration from 14.7-13.4 Ma. Precise age control allows analysis of cyclical aspects of chert and dolomite to be carried out on the section. Frequency estimates of silica-carbonate cycles at Ano Nuevo suggest that the cycles may be related to early middle Miocene paleo-oceanographic events. In the Santa Maria basin, where black quartz cherts are widespread, diatom biostratigraphy has been successfully applied on the Mussel Rock, Lions Head, and Shell Beach sections. Preliminary data suggest black chert intervals are strongly age controlled and are possibly related to Miocene cooling events that affected the Santa Maria basin. Ongoing studies of the diatom biostratigraphy of dolomites promise improved age control in the Santa Maria basin. This will not only aid in paleo-oceanographic interpretations, but will also improve constraints on tectonic and depositional aspects of the basin.

    The pattern of microhabitat preferences of Ukrainian brook lamprey Eudontomyzon mariae ammocoetes was examined in two rivers of central Poland: the Pilica River (the Vistula River basin) and the Grabia River (the Odra River basin). A comparison of abiotic factors of the rivers revealed differences in water speed and principal components: PC1 (determining gradient from decreasing medium sand to the increasing share of three fractions of gravel), PC2 (a gradient from the declining share of very coarse and coarse sand fractions to the growing content of fine sand) and PC3 (correlated with an increasing proportion of silt). The sites did not differ significantly in terms of water depth. Relative abundance and frequency of ammocoete occurrence in the Grabia River were higher than in the Pilica River. Only speed, PC1 and PC2 made a significant contribution to the prediction of larval occurrence. Eudontomyzon mariae larvae preferred substrata with a reduced amount of medium sand and increased content of gravel (PC1) as well as with a lower content of coarse sand and higher proportion of fine-grained sand (PC2). The ammocoetes also preferred areas with a water speed of 0·2 m s(-1) but avoided speeds ≥ 0·6 m s(-1). The abundance of E. mariae was affected by water speed, as well as by all PCs. The mean ± s.e. optimal current speed was 0·265 ± 0·007 m s(-1), while abundance decreased with increasing amounts of gravel (PC1) and increased with increasing amounts of fine sand and silt in the bottom substratum (PC2 and PC3). Comparison of ammocoete microhabitat use in the Pilica and Grabia Rivers showed the lack of differences in distribution in the preferred values of current speed, PC1 and PC2.

    Oceanic volcanic islands typically evolve through large-scale short-term events, either constructing or destructing the volcanic edifice. This tug of war between construction and catastrophic destruction should be recorded within a volcanic island, but old collapse events are sometimes hard to recognize because a number of processes modify the associated structures; therefore, recognition of the testimony of such events onshore, without recourse to offshore high-resolution bathymetry, is challenging and comprises our main objective. Additionally, no large-scale catastrophic sector collapses have ever been reported in the Azores, which makes Santa Maria Island a particularly interesting target. In Santa Maria, lava flows of the two main sub-aerial volcanic complexes dip gently to the west, they are separated by a volcano-sedimentary complex lying on an unconformity dipping gently to the east, and the ages decrease to the east. From this geometry and geochronology, we infer that: (1) more than half of the early shield volcano is missing (absence of all eastern flank, summit and part of the western flank), which we interpret as a large-scale sector collapse whose scar is in part the east-dipping unconformity covered with sediments ca. 4.2 Ma old; (2) the scar was filled by a younger shield volcano that grew very rapidly (ca. 4.0-3.6 Ma); (3) a second large-scale sector collapse followed, which again spared only part of the western flank of the younger shield volcano; (4) new volcanism made of dykes and volcanic cones aligned with the arcuate collapse scar indicate that the slide may have occurred ca. 3.6 Ma ago. We conclude that Santa Maria records onshore evidence of two large-scale sector collapses.

    The article was written on the occasion of the 100. anniversary of the Nobel Prize in Chemistry awarded to Maria Skłodowska-Curie. The United Nations General Assembly honoured this event by announcing the year 2011 the International Year of Chemistry. Maria Skłodowska-Curie was i.a. the initiator of radiation chemistry, a branch of science analyzing the chemical effects that matter shows when exposed to ionizing radiation. The development of this branch resulted in radiation technologies' applications in many fields of industry, medicine, agriculture, protection of the environment, space research and science. Our point of departure was the article Sur l'etude des courbes de probabilité relatives a l'action des rayons X sur les bacilles that Maria Skłodowska-Curie published in 1929 in the Bulletin of the Académie des sciences. In this study, she presented--for the first time ever--the curves of the so called radiation inactivation, i.e. the relationship between the bacteria life expectancy and the dose of radiation absorbed by it. From the today's point of view, it can be stated that the researcher laid the foundations of the methods of radiation sterilization and material processing by means of radiation. In this context, we recall the history of the first accelerator installation devised and built in 1968 at the Institute of Nuclear Chemistry and Technology in Warsaw. Basing on experiences with the linear electron accelerator, the LAE 13/9 was completed in 1992 as the so far only Polish industrial installation for radiation sterilization of medical products and transplants as well as for food irradiation.

    A pinhole camera has the advantage of undistorted field of view. Its imaging capability is limited by random (diffraction and atmospheric seeing) and systematic (penumbra) effects. The Pinhole Solar Monitor, PSM, measures the solar angular diameter by timing meridian transits. Meridian transits have been videorecorded with UTC synchronization at the pinhole gnomon of Santa Maria degli Angeli church in Rome. The tarature of this Clementine Gnomon is outlined with its accuracy as PSM. On the Moon an array of such PSM equipped with 1000 lines for parallel transits can monitor 0.1” variations of solar diameter.

    Hydropower is the main electricity source of Brazil. The related hydropower reservoirs are multi-purpose thus besides efficient and reliable energy production, they are relevant for flood control. In this context, the present study shows results of an Ensemble Streamflow Prediction (ESP) for supporting the operational decision making implemented at Três Marias hydroelectric power project located in the São Francisco River basin in Brazil. It is a large tropical river basin with approximately 55,000km² up to the Três Marias dam. The hydrological model used in the study is the MGB-IPH (Modelo de Grandes Bacias from Instituto de Pesquisas Hidráulicas), a large scale distributed hydrological model. Applied in an operational forecasting mode, it uses an empirical data assimilation method to take into account real time streamflow observations to update its state variables. We present results of a hindcast experiment with observed precipitation and streamflow data from the local energy utility, CEMIG (Companhia Energética de Minas Gerais), and from the Brazilian water agency, ANA (Agencia Nacional de Água),. Probabilistic Numerical Weather Predictions (NWP) from CPTEC (Centro de Previsão de Tempo e Estudos Climáticos), ECMWF (European Centre for Medium-Range Weather Forecast) and NOAA (National Oceanic and Atmospheric Administration) are used to generate the ESP. The data products and the MGB-IPH model are integrated into an open shell forecasting platform based on the software package Delft-FEWS. Inside the forecasting platform a hindcast mode over a forecast lead time of 10-16 days in recent rainfall periods is applied in. The ESP results are compared to deterministic forecasts of the Três Marias reservoir inflow. The results assessment verifies the added value of the ESP in general in comparison to the use of deterministic forecasts by means of different performance indicators. The ESP derived from the ECMWP ensemble shows the best performance. A future

Three different types of data were combined to estimate two-dimensioanl station positions and strain rate parameters simultaneously: (1) historical triangulation from the 1880s, 1920s, and 1950s; (2) electronic distance measurement trilateration from 1971 and 1985; and (3) GPS observations from 1986 and 1987. Results imply that the SMFTB is the primary active element in transforming motion from the Coast Ranges to the western Transverse Ranges and the Santa Barbara Channel.

Her teaching method--the Montessori Method- is still used worldwide--Because she could not speak English during the imprisonment in India, there was a big obstacle for her communication with children. However, the need to adopt a non-verbal communication, led her to a sensational discovery: children use an innate and universal language. This language, made of gestures and mimic, is called extra verbal communication. PMID:26203578

    Paleopositions for southern Baja California peninsula have yielded controversial models over the past 30 years. Mainly based on paleomagnetic data many hypotheses place Baja at lower paleolatitudes in front of southern Mexico or Central America with subsequent northward translations. Other models suggest minor, if any, northward displacements with respect to continental Mexico combined with clockwise rotations. Lithological, geochemical, and geochronological similarities for southern Baja California and Puerto Vallarta (western Mexico Pacific margin) igneous rocks seem to confirm the latter model. To further prove this model we have mapped and collected rocks from Maria Madre, the largest island of the Islas Marias archipelago, located in the mouth of the Gulf of California. In an area of only 145 square kilometers, metamorphic basements rocks (ortho and migmatitic gneisses), highly deformed metasediments, granitoids, acid to intermediate volcanic sequences, and a cover with gently folded marine sediments are exposed. The basement complex with gneisses and metasediments, including garnet-bearing paragneiss and calc silicates, as well as the granodioritic-tonalitic intrusives display an extraordinary accordance with similar units observed in the Los Cabos Block (LCB) of Baja California Sur. Furthermore, U-Pb zircon ages of 162 and 170 Ma for the basement gneisses and of 80 Ma for the granitoids have been reported also from the LCB. Additionally, upper Cretaceous intrusive ages are well known from the Puerto Vallarta batholith in Jalisco and Nayarit, mainland Mexico. Geochemical and isotopic data as well as Nd model ages confirm a magmatic consanguinity of LCB, Islas Marias, and Puerto Vallarta granitoids. The volcanic units of Maria Madre Island include ignimbrites and effusive dacitic-rhyolithic rocks, which can be correlated to the Sierra Madre Occidental province and the Comundú Formation of Baja California. Age determinations are under work to confirm this

    The Santa Maria basin of central California is a geologically complex area located along the tectonically active California continental margin. The record of Cenozoic tectonism preserved in Santa Maria strata provides an opportunity to compare the evolution of the region with plate tectonic models for Cenozoic interactions along the margin. Geohistory analysis of Neogene Santa Maria basin strata provides important constraints for hypotheses of the tectonic evolution of the central California margin during its transition from a convergent to a transform plate boundary. Preliminary analyses suggest that the tectonic evolution of the Santa Maria area was dominated by coupling between adjacent oceanic plates and the continental margin. This coupling is reflected in the timing of major hiatuses within the basin sedimentary sequence and margin subsidence and uplift which occurred during periods of tectonic plate adjustment. Stratigraphic evidence indicates that the Santa Maria basin originated on the continental shelf in early Miocene time. A component of margin subsidence is postulated to have been caused by cessation of spreading on adjacent offshore microplates approximately 19-18 ma. A sharp reduction in rate of tectonic subsidence in middle Miocene time, observed in the Santa Maria basin both onshore and offshore, was coeval with rotation of crustal blocks as major shearing shifts shoreward. Tectonic uplift of two eastern sites, offshore Point Arguello and near Point Sal, in the late Miocene may have been related to a change to transpressional motion between the Pacific and North American plates, as well as to rotation of the western Transverse Ranges in a restraining geometry.

    A primarily analysis of marine geophysical data acquired aboard the RRS James Cook in the framework of the project "Characterization of seismic hazard and tsunami associated with cortical contact structure Rivera Jalisco Block Plate (TSUJAL)" is presented. This survey was held in the region of Nayarit-Tres Marias Islands between February and March 2014. The examination of data recorded by 16 OBS 's, deployed along 4 wide angle seismic profiles is presented, using an airgun-array seismic source of 6800 c.i., which allows sampling the crustal structure to the Moho. The profiles are located along the margin off the Marias Islands: a profile of over 200 km NNW-SSE direction and parallel to the western flank of the Islas Marias Islands and three orthogonal thereto. These perpendicular sections sample the lithosphere from the north of Maria Madre Island with a profile of 100 km length, across Maria Magdalena and Mari Cleofas Islands, with a profile of 50 km long, till south of Maria Cleofas with a profile of 100 km long. Coincident multichannel seismic profiles with refraction ones are also surveyed, although shooting with a source of 3,540 c. i., and acquired with a digital "streamer" of 6.0 km long. Simultaneously, multibeam, parametric and potential field data were recorded during seismic acquisition A first analysis shows an anomalously thickened crust in the western flank of the Marias Islands, as indicated by relatively short pre-critical distances of 30-35 km. While the moderate dip of 7 ° of the subduction of the Pacific oceanic plate favors somehow this effect, the existence of a remnant crustal fragment is also likely. Moreover, the images provided by the parametric sounding show abundant mass wasting deposits suggesting of recent active tectonics, possibly generated by earthquakes with moderate magnitude as those reported in the Marias Islands. This set of geophysical data, not only provide valuable information for the seismogenic characterization and

    Compilation from published records of 30 pre-Miocene stratigraphic columns in the Santa Maria basin area of California (west of the Sur-Nacimiento fault and north of the Santa Ynez fault) reveals two basement units and 22 overlying sedimentary units. This article displays the stratigraphic columns and includes descriptions and environmental interpretations of the 24 rock units. The basement rocks include an Upper Jurassic ophiolite sequence and the Lower Jurassic through Upper Cretaceous Franciscan Complex. Most of the 22 sedimentary units were deposited along a subduction-type margin prior to development of the late Tertiary Santa Maria basin. Overlying and generally in fault contact with the basement rocks are four Upper Jurassic through Lower Cretaceous units that were deposited in basin plain and out continental margin environments. Unconformably overlying these units are eight Upper Cretaceous units that were deposited in a wide range of environments that ranged from trench, slope, and submarine fan up through shelf and nonmarine fluvial environments. Lower Tertiary units onlap unconformably onto the Cretaceous rocks and were deposited only in the southernmost part of the area. These rocks include lower Eocene basin plain and outer submarine fan deposits; middle Eocene mid-fan and slope deposits; upper Eocene inner fan, shelf, shoreface, and foreshore deposits; and Oligocene shoreface, foreshore, and nonmarine fluvial deposits.

    BNCT facility in the Institute of Atomic Energy in Otwock-Swierk is under construction at the horizontal channel H2 of the research reactor MARIA. Measurements of the neutron energy spectrum performed at the front of the H2 experimental channel, have shown that flux of epithermal neutrons (above 10 keV) at the BNCT irradiation port was below 109 n cm-2 s-1 i.e. it was too low to be directly used for the BNCT treatment. Therefore, a fission converter will be placed between the reactor core and the periphery of the graphite reflector of MARIA reactor. The uranium converter will be powered by the densely packed EK-10 fuel elements with 10% enrichment. Preliminary calculations have shown that the total neutron flux in the converter will be about 1013 n cm-2 s-1 and flux of epithermal neutrons at the entrance to the filter/moderator of the beam will be about 2·1013 n cm-2 s-1.

    Islas Marias Archipelago consists of four islands located in the mouth of the Gulf of California. Lithologically three of them (Maria Madre, San Juanito, and Maria Cleofas) are quite similar with a 165-170 Ma metamorphic basement, 75-85 Ma intrusive and extrusive rocks, and a sedimentary sandstone cover, which according to its foraminiferous content recorded multiple uplift and subsidence events related to the opening of the Gulf. However, these units are absent on Maria Magdalena island which is positioned between the other islands. Here, instead, oceanic lithosphere with pillow lavas and gabbroic sills, intercalated with sandstones form the dominant outcrops. Their geochemical and isotopic characteristics are similar to N-MORB with epsilon Nd values around +10 and 87Sr/86Sr of 0.70290. The gabbros are not older than 22 Ma. Magdalena island was obviously uplifted separately from the other islands of the archipelago, probably along a now hidden transform fault system along the East Pacific Rise. Metamorphic and igneous rocks of the other islands can be correlated to lithologically similar units in the Los Cabos Block, Baja California, or to the continental margin units in Sinaloa, Nayarit and Jalisco states when looking at their geochemical and geochronological signatures. Paleomagnetic studies on 35 sampling sites from all 4 islands give evidence for relatively small scale tectonic movements.

    Reactor kinetic parameters, reactivity feedback coefficients, and control rod reactivity worths have been calculated for the MARIA Research Reactor (Swierk, Poland) for M6-type fuel assemblies with {sup 235}U enrichments of 80% and 19.7%. Kinetic parameters were evaluated for family-dependent effective delayed neutron fractions, decay constants, and prompt neutron lifetimes and neutron generation times. Reactivity feedback coefficients were determined for fuel Doppler coefficients, coolant (H{sub 2}O) void and temperature coefficients, and for in-core and ex-core beryllium temperature coefficients. Total and differential control rod worths and safety rod worths were calculated for each fuel type. These parameters were used to calculate generic transients for fast and slow reactivity insertions with both HEU and LEU fuels. The analyses show that the HEU and LEU cores have very similar responses to these transients.

    The quality and quantity of recharge to the Santa Maria Valley, Calif., ground-water basin from natural sources, point sources, and agriculture are expressed in terms of a hydrologic budget, a solute balance, and maps showing the distribution of select chemical constituents. Point sources includes a sugar-beet refinery, oil refineries, stockyards, golf courses, poultry farms, solid-waste landfills, and municipal and industrial wastewater-treatment facilities. Pumpage has exceeded recharge by about 10,000 acre-feet per year. The result is a declining potentiometric surface with an accumulation of solutes and an increase in nitrogen in ground water. Nitrogen concentrations have reached as much as 50 milligrams per liter. In comparison to the solutes from irrigation return, natural recharge, and rain, discharge of wastewater from municipal and industrial wastewater-treatment facilities contributes less than 10 percent. The quality of treated wastewater is often lower in select chemical constituents than the receiving water. (Woodard-USGS)

    This paper proposes the use of discrete wavelet transform (DWT) to remove the high-frequency components (details) of an original signal, because the noises generally present in time series (e.g. streamflow records) may influence the prediction quality. Cleaner signals could then be used as inputs to an artificial neural network (ANN) in order to improve the model performance of daily discharge forecasting. Wavelet analysis provides useful decompositions of original time series in high and low frequency components. The present application uses the Coiflet wavelets to decompose hydrological data, as there have been few reports in the literature. Finally, the proposed technique is tested using the inflow records to the Três Marias reservoir in São Francisco River basin, Brazil. This transformed signal is used as input for an ANN model to forecast inflows seven days ahead, and the error RMSE decreased by more than 50% (i.e. from 454.2828 to 200.0483).

    The 2009 L'Aquila, Italy earthquake highlighted the seismic vulnerability of historic masonry building structures due to improper "strengthening" retrofit work that has been done in the last 50 years. Italian seismic standards recommend the use of traditional reinforcement techniques such as replacing the original wooden roof structure with new reinforced concrete (RC) or steel elements, inserting RC tie-beams in the masonry and new RC floors, and using RC jacketing on the shear walls. The L'Aquila earthquake revealed the numerous limitations of these interventions, because they led to increased seismic forces (due to greater additional weight) and to deformation incompatibilities of the incorporated elements with the existing masonry walls. This paper provides a discussion of technical issues pertaining to the seismic retrofit of the Santa Maria di Collemaggio Basilica and in particular, the limitations of the last (2000) retrofit intervention. Considerable damage was caused to the church because of questionable actions and incorrect and improper technical choices.

  7. Heat transport by fluids during late Cretaceous regional metamorphism in the Big Maria Mountains, southeastern California.

    The Big Maria Mountains of SE California preserve evidence of a large-scale fluid flux that accompanied regional metamorphism in late Cretaceous time. Neither magmatism nor radioactive heat sources are adequate to explain the T of metamorphism. Simultaneously crystallizing plutons at different levels within the crust could have contributed to the overall hot fluid flux. A fluid:rock ratio of 17:1 may be calculated given average conditions of 3 kbar, 500oC, an infiltrating fluid of composition XH2O = 1.0, an equilibrium fluid composition of XH2O = 0.97, and 90% wollastonite in the final rock form the reaction quartz + calcite = CO2 + wollastonite. The minimum quantity of fluid of 1.7 rock volume was estimated to pass through the area if the fluid was approximately at granite solidus T at the start. Deep penetrative structures within the crust may have served to channel fluids. -L.C.H.

    Concentrations of 11 trace metals (Fe, Mn, Cr, Cu, Ni, Co, Pb, Zn, Cd, As, Hg) in 40 fish species from Santa Maria Bay, Baja California Sur, Mexico, the strategically important area for marine mammals and organisms were analyzed. Based on their concentrations the ranking of metals Fe>Zn>Ni>Cr>Mn>Pb>Cu>Co>As>Cd>Hg suggests that organism size, metabolism and feeding habits are correlated with metal concentrations. Local geological formations affect the concentrations of different metals in the aquatic environment and are subsequently transferred to fishes. The correlation analysis suggests that metabolism and nurturing habits impact the concentration of metals. Concentrations of Fe and Mn appear to be influenced by scavenging and absorption processes, which vary by species. The considerable variability in the metal concentrations obtained in different species underscores the importance of regular monitoring.

    This article sheds light on Maria Bandeira, the first female botanist to work at the Botanic Garden of Rio de Janeiro. She was active in the 1920s, but is absent from the historiography and little cited in the scientific literature. The significant number of plant, fungus, and lichen specimens she collected, her capacity to reach far-flung places, her extensive correspondence with foreign experts, and her studies at Sorbonne are all sources for the analysis of the way botany was practiced and the social networks at play in science at the time. The end of her scientific career, when she adopted a cloistered life with the Barefoot Carmelite nuns, can be interpreted variously, and partially explains why her contributions to Brazilian botany have been forgotten.

    On January 27, 2013, a fire at the Kiss Nightclub in Santa Maria, Brazil led to a mass-casualty incident affecting hundreds of college students. A total of 234 people died on scene, 145 were hospitalized, and another 623 people received treatment throughout the first week following the incident.1 Eight of the hospitalized people later died.1 The Military Police were the first on scene, followed by the state fire department, and then the municipal Mobile Prehospital Assistance (SAMU) ambulances. The number of victims was not communicated clearly to the various units arriving on scene, leading to insufficient rescue personnel and equipment. Incident command was established on scene, but the rescuers and police were still unable to control the chaos of multiple bystanders attempting to assist in the rescue efforts. The Municipal Sports Center (CDM) was designated as the location for dead bodies, where victim identification and communication with families occurred, as well as forensic evaluation, which determined the primary cause of death to be asphyxia. A command center was established at the Hospital de Caridade Astrogildo de Azevedo (HCAA) in Santa Maria to direct where patients should be admitted, recruit staff, and procure additional supplies, as needed. The victims suffered primarily from smoke inhalation and many required endotracheal intubation and mechanical ventilation. There was a shortage of ventilators; therefore, some had to be borrowed from local hospitals, neighboring cities, and distant areas in the state. A total of 54 patients1 were transferred to hospitals in the capital city of Porto Alegre (Brazil). The main issues with the response to the fire were scene control and communication. Areas for improvement were identified, namely the establishment of a disaster-response plan, as well as regularly scheduled training in disaster preparedness/response. These activities are the first steps to improving mass-casualty responses. PMID:25544145

    The Lospe Formation is an 800-m-thick sequence of sedimentary and minor volcanic rocks at the base of the petroliferous Neogene Santa Maria basin of central California. In its type area in the Casmalia Hills, the Lospe rests unconformably on Jurassic ophiolite, is conformably overlain by the lower Miocene (Sauceian and Relizian) Point Sal Formation, and is of earliest Miocene (Saucesian) age on the basis of palynomorphs, benthic foraminifers, and radiometric dating of tuffs. Alluvial fan and fan-delta facies at the base of the Lospe are as much as 200 m thick and consist mainly of conglomerate and sandstone derived from nearby fault-bounded uplifts of Mesozoic rocks. These coarse sediments grade upward into a sequence of interbedded turbidite sandstone and mudstone that accumulated in a lake or restricted coastal embayment. Lenses of tuff as much as 20 m thick occur sporadically throughout this sequence and contain blocks of Jurassic ophiolite up to 50 m long and 20 m across. The uppermost 30 m of the Lospe consist of storm-deposited sandstone and mudstone containing shallow marine microfossils. That these shelf deposits are abruptly overlain by black shale of the Point Sal Formation indicates rapid deepening to oxygen-poor bathyal environments. Overall, the Lospe Formation is a fining-upward sequence that records active faulting, volcanism, and a change from nonmarine to marine depositional environments during the initial formation of the Neogene Santa Maria basin. This history is consistent with several competing tectonic models that variously explain the origin of the basin as the result of regional rifting or local rotation of small crustal blocks.

    The need to anticipate the potential impact of oil exploration and production activities on coastal resources, and the information needs of agencies charged with responding to coastal emergencies motivated the development of the oil-spill response system for the Santa Barbara Channel (SBC) and the Santa Maria Basin (SMB), along the California coast, between Ventura and Morro Bay. In the Santa Barbara Channel (SBC), moorings and drifter trajectories document a persistent cyclonic circulation with a typical re-circulation period between three and five days. In the spring currents near the mainland are weaker than near the Channel Islands and the overall flow is toward the southeast. Trajectories document the possibility for water parcels to leave the channel through the inter-island passes. In the late fall and winter, a poleward flow with velocities often exceeding 0.5 m/s is confined within 20 km of the mainland. Between these two seasons, the cyclonic tendency is enhanced although most of the drifters eventually migrate westward. The trajectories of drifters released at the same time from sites only 20 km apart can be remarkably different. In the Santa Maria Basin (SMB), the direction and amplitude of the flow is strongly depth dependent. Near the surface, moorings and drifters show the flow to be equatorward except during late fall and early winter when the surface flow is poleward. Beneath the surface layer the flow is poleward except in March and April, right after the spring transition. The observations provide a basis on which several data assimilating model of the circulation are based. The models reproduce all the major observed features of the circulation, including individual drifter trajectories. With little effort these models could be used to maintain an operational predictive capability with real predictive skills over periods of a few days.

    Lupinus mariae-josephae is an intriguing lupine species recently discovered in the Mediterranean region and constitutes an endemism of a small area of Eastern Spain (Valencia province; Pascual, 2004; Mahé et al. 2011). It opens new perspectives for ecological and agronomic interests, as it represents the sole lupine species that preferentially grows in basic soils, while almost all other lupine species occur in acid to neutral soils. The L. mariae-josephae symbionts isolated from soils of calcareous areas of Valencia are extremely slow-growing bacteria belonging to the Bradyrhrizobium genus and showing symbiotic specificity that prevents nodulation of other Lupinus spp. such as L. angustifolius or L. luteus typically thriving in acid soils (Sanchez-Cañizares et al, 2011). Their phylogenetic analysis based on housekeeping and symbiotic genes showed that L. mariae-josephae symbionts belong to an evolutionary lineage that also includes endosymbiotic bacteria from Retama spp. of Northern Algeria basic soils (Boulila et al. 2009). Conversely, this new lineage is phylogenetically distinct from that of endosymbiotic bacteria from other Lupinus spp. native of the Iberian Peninsula, which were nested mainly within B. canariense and B. japonicum lineages. A genomic diversity study of the indigenous bradyrhizobia population of the calcareous areas in Valencia, based on fingerprint and phylogenetic analysis, showed the existence of a large diversity of genotypes, some of which are related to bacteria from the Retama spp. symbiosis in Algeria. This singular genomic divergence of L. mariae-josephae symbiotic bacteria in such a small geographical area fosters attractive studies on the origin, ecology and evolution of both partners of the symbiosis. Furthermore, it is expected that ongoing seed inoculation experiments with selected strains will allow us to extend the extant distribution spots of L. mariae-josephae plants in Valencia area, and also to determine whether the

    In 1911, when the Nobel Foundation awarded its coveted Chemistry Prize to a 44 year old Polish born woman, it is likely they may not have expected the action ever duplicated in the more than 100 years that followed. In fact, it was the second Nobel Prize in the sciences awarded to Maria Sklodowska-Curie, whom the world would come to admire, know, and love as Madame Curie. In a time of science dominated by men, the diminutive in size but larger-than-life Curie would become the first women to be awarded the prize. To this date, she remains the only person in history to win two Nobel prizes in two different science fields, and only one of four persons to win more than one. In total, Mme. Curie and her immediate family would be awarded five Nobel prizes. As astonishing as these facts may be, Mme. Curie did not seek fame nor did she seek self aggrandizement. Her whole life was one of service to humanity, an indefatigable work ethic, and humility. PMID:25337133

We observed seismic swarms and low magnitude. Within our data set we identified four seismic swarms episodes. September 14 to 15, 2010 that starts with an earthquake of M = 5.6 at 23:31 followed by approximately 27 events, also has six earthquakes whose magnitudes are between M = 4.0 and M = 5.6; November 11 to December 5, 2011 which contains more than 25 events; October 12 to November 17, 2012 with more than 35 events with an earthquake M = 4.7 occurred on October 29; and finally the swarm occurred between January 20 and February 14, 2013 with over 120 events and one of M = 4.7 occurred on January 22. The last seismic swarm also present activity along two additional areas, one toward the west and the other toward the east of active area previously identified. This seismic activity is associated with the northern edge of the Barra de Navidad Trench whose geometry is unknown. Tectonic structures associated with this seismicity can be tsunamigenic and could represent a danger to nearby populations.

    A map of TiO2 abundance for most of the northern maria is presented. The telescopic data base used is the 0.38/0.56-micron ratio mosaic from Johnson et at. (1977). The titanium content has been estimated using the correlation established by Charette et al. (1974). The combination of observational, processing, and calibration errors indicates that the TiO2 map is accurate to + or - 2% (wt% TiO2) for high TiO2 content (more than 5%) and + or - 1% for low values of TiO2. Analysis of the lunar sample and telescopic data suggests strongly that the spectral parameter mapped is sensitive primarily to TiO2 abundance in the range 3-9% and does not correlate directly with iron content. It is suggested, however, that for the low TiO2 mare regions (less than 2-3% TiO2) there may be a relation between the spectral ratio and iron content and that some of the reddest mare areas in the Imbrium region may have low iron contents as well as low titanium abundances.

    Historical archaeology may be characterised by an intricate relationship between written sources and material remains. In research focusing on shipwrecks, this often results in descriptions of the events associated with one particular ship. These are narratives written from a historical horizon, where written sources provide the explanation to material remains. The aim of this paper is to show that a combination of material remains and written sources may be used as a departure point for a discussion on social conditions on board merchant ships in a more general sense. The case used is the fluit or fluitship Anna Maria, launched in 1694 and which foundered in Dalarö harbour, Sweden, in 1709. The site is ideal for such a study partly as it has been surveyed archaeologically on several occasions since the 1960s and most recently in 2010, and partly because historical research has been carried out on the related written accounts. Taken together, this material enables a unique opportunity to reconstruct and study the everyday environment on board a large fluitship.

    Dolichoderus mariae Forel, (Hymenoptera: Formicidae) is an uncommon, monomorphic but locally abundant, reddish-brown ant of peculiar nesting habits, whose range includes most of the eastern USA. In north Florida the ant excavates soil under wiregrass clumps or other plants with fibrous roots to form a single, large, shallow, conical or ovoid chamber broadly open to the surface around the plant base. Colonies are highly polygyne and, during the warm season, inhabit multiple nests connected only by above ground trails, over which nests exchange workers. Although monomorphic, worker size may differ significantly between colonies. The colony cycle is dominated by strong seasonal polydomy. From one or two over-wintering nests, the colonies expanded to occupy up to 60 nests by late summer, then retract once more to one or two nests by mid-winter. The worker-to-queen ratio changed greatly during this cycle, with over two thousand workers per queen during fall and winter, dropping to a low of about 300 during midsummer. Most of these summer queens probably die during the fall. Colonies reoccupy roughly the same area year to year even though they contract down to one or two nests in winter. Observation of fights in the contact zone between colonies suggested that the colonies are territorial. The ants subsist by tending aphids and scale insects for honeydew and scavenging for dead insects within their territories.

    Gills of Maria-da-toca Hypleurochilus fissicornis collected at Ponta do Sambaqui-Florianópolis island-Brazil, were analyzed to describe the histopathology caused by metacercaria of Bucephalus margaritae. Gills were submitted to the routine histological techniques for embedding in paraffin and permanent mounting in Balsam and stereoscopic analysis. Metacercariae showed a branchial infection site pattern for encystations. The branchial infection site pattern is half-basalward in the primary branchial filament with amplitude of the infection of 1-3 metacercaria. Cysts occurred within branchial abductor muscle and cartilaginous and osseous tissues of the gills. Each metacercariae had a contentional hyaline parasitic capsule and melanin-like pigmentation. The half-apicalward region of the primary branchial filaments showed several dysplasia degrees, cartilage and osseous degeneration (pyknosis), thrombosis and immune exudated cells (mainly lymphocytes). Cytopathologies as thickening of the epithelium lining of the secondary branchial filaments were a response of the branchial infection site pattern of the metacercaria. Interlamellar obliteration and fusion of the lamellae due to the hypertrophy and hyperplasia of the epithelial lining as well as chloride cells occurred. Pyknosis of pillar cells and epithelial lining cells from the secondary branchial filaments were also present. Bucephalosis in H. fissicornis gills is no-hemorrhagic and no-fatal branchitis, but could compromises the gill functions and could permits the secondary opportunistic infections.

    In 1911, when the Nobel Foundation awarded its coveted Chemistry Prize to a 44 year old Polish born woman, it is likely they may not have expected the action ever duplicated in the more than 100 years that followed. In fact, it was the second Nobel Prize in the sciences awarded to Maria Sklodowska-Curie, whom the world would come to admire, know, and love as Madame Curie. In a time of science dominated by men, the diminutive in size but larger-than-life Curie would become the first women to be awarded the prize. To this date, she remains the only person in history to win two Nobel prizes in two different science fields, and only one of four persons to win more than one. In total, Mme. Curie and her immediate family would be awarded five Nobel prizes. As astonishing as these facts may be, Mme. Curie did not seek fame nor did she seek self aggrandizement. Her whole life was one of service to humanity, an indefatigable work ethic, and humility.

    The biodiversity of the Santa Maria di Leuca (SML) coral bank is summarized and its description is updated using data collected by means of underwater video systems, benthic samplers and fishing gears. A total of 222 living species have been recorded within the coral bank area in the depth range 280-1121 m. The most abundant benthic taxa recorded are Porifera (36 species) followed by Mollusca (35) and Cnidaria (31). The scleractinian corals Madrepora oculata and Lophelia pertusa are the main colonial species in the structure of the SML bank. Annelida, Crustacea and Bryozoa have been found with 24, 23 and 19 species, respectively. A total of 40 species of demersal fish have been recorded. Other faunal taxa were found with small numbers of species. One hundred and thirty-five species are new for the SML bank, 31 of which represent new records for the north-western Ionian Sea (2 Porifera, 17 Cnidaria, 1 Mollusca, 3 Annelida, 2 Crustacea, 4 Bryozoa and 4 Echinodermata). The finding of the annelid Harmothoë vesiculosa represents the first record for the Mediterranean Sea. The SML coral bank represents a biodiversity "hot-spot" on the bathyal bottoms of the Mediterranean Sea.

    The versatile helicon plasma device, MARIA (Magnetized AnisotRopic Ion-distribution Apparatus), was upgraded with stronger magnetic field B <= 1200G. The main focus is to understand the neutral particle dynamics and ionization mechanism with helicon waves to establish a high-density plasma (10 ∧ 20/m ∧ 3) at substantial electron (Te ~5-15eV) and ion (Ti ~1-3eV) temperature. To achieve this, installation of higher RF Power <= 15kW is planned as well as design of an ion cyclotron-heating antenna. To quantify the plasma characteristics, diagnostics including a Triple Langmuir Probe, Emissive Probe, and Laser Induced Fluorescence were established. We show first results from characterization of the device. The coupling of the helicon mode in the electron temperature and density parameter space in Argon was mapped out with regard to neutral pressure, B-field and RF power. In addition, validity of the Bohm Criterion and of the Chodura model starting in the weakly collisional regime is tested. A key goal in all efforts is to develop methods of quantitative spectroscopy based on cutting-edge models and active laser spectroscopy. This work was funded by Startup funds of the Department of Engineering Physics at UW Madison, the NSF CAREER award PHY-1455210 and NSF grant PHY-1206421.

    Several regional-scale, fluorescent dye-tracing tests recently showed counter-intuitive, tectonically influenced, preferential ground water flow from the Piora Region via the Santa Maria Valley to the di Campo Valley. Losing rivers of the Piora Valley recharge the Triassic Piora Aquifer at an average rate of 20,000 m3/d and hydrologic budgets suggest that half of the Upper Santa Maria discharge originates from the Piora Region. The geologic map of the Upper Santa Maria Valley presented a partial solution to the hydrogeologic puzzle of the Piora Aquifer, thus facilitating construction of the AlpTransit railway tunnel (the longest on Earth). The autochthonous Lucomagno Triassic of the Gotthard Massif (cargneules), the allochthonous Frodalera-Peiden Triassic (sugar dolomites, para-gneises, quartzites, green phyllites), the Stgir Series of the Lower Jurassic (sandy limestones and quartzites), the Inferno Series of the Middle Jurassic (coarse sandstones, limestones, shales), the Coroi Series of the Upper Jurassic (black shales), the crystalline Gotthard Massif (ortho-gneises), and the northern Penninic Nappe (para- and ortho-gneises, quartzites) are the main lithologies found in the outcrops of the Upper Santa Maria Valley. The highly weathered Triassic series found in the Piora and Upper Santa Maria Valley posed a potential hydrogeologic obstacle that was overcome by tunnel drillers in early 2010, for expected tunnel service by 2012.

    Aetosaurs are armored pseudosuchian archosaurs widespread in Upper Triassic units. In South America, four taxa were previously recorded: Aetosauroides scagliai, Neoaetosauroides engaeus, Aetobarbakinoides brasiliensis, and Chilenosuchus forttae. Herein we describe a new Late Triassic juvenile aetosaur from the Santa Maria Formation of southern Brazil, Polesinesuchus aurelioi gen. et sp. nov., increasing the paleobiodiversity of this interesting group to five taxa in Western Gondwana. The holotype is composed of cranial (parietal and braincase) and postcranial elements (cervical, dorsal, sacral, caudal vertebrae, both scapulae, a humerus, ilium, pubis, ischium, tibia, a partial right pes, and anterior and mid-dorsal paramedian osteoderms). It belongs to a juvenile individual, as its neurocentral sutures are open in all vertebrae, and also due to its small size. However, future paleohistological investigation is necessary to fully corroborate this assumption. This new taxon is distinguished from all other aetosaurs by the presence of an unique combination of character states (not controlled by ontogeny) such as: cervical vertebrae with prezygapophyses widely extending laterally through most of the anterior edge of the diapophyses; absence of hyposphene articulations in both cervical and mid-dorsal vertebrae; presence of a ventral keel in cervical vertebrae; anterior and mid-dorsal vertebrae without a lateral fossa in their centra; expanded proximal end of scapula; anteroposteriorly expanded medial portion of scapular blade; a short humerus with a robust shaft; and a dorsoventral and very low iliac blade with a long anterior process which slightly exceeds the pubic peduncle. Regarding its phylogenetic relationships, the present analysis placed Polesinesuchus as the sister taxon of Aetobarbakinoides and both as sister taxa of the unnamed monophyletic clade Desmatosuchinae plus Typothoracisinae. 

  14. Maria Goeppert Mayer's work on beta-decay and pairing, and its relevance today

    Maria Goeppert Mayer's work on beta-decay and pairing is not as well known as her Nobel Prize winning work on the nuclear shell model, but it attests to her wide range of accomplishments. Her paper on double beta decay was the first one written on the subject. Later she also worked on the application of beta decay as a test of the nuclear shell model. Due to its very long half-life, double beta-decay was not found experimentally until the 1980's. This involves emission of two neutrinos along with the two electrons. However, in principle it is also possible to have double beta decay with no neutrinos, a process which was identified about 10 years ago, though this is still quite controversial. Currently, there are several groups working on this problem, which has significant implications for particle physics and for cosmology. It was known from the earliest days of nuclear physics that nuclei with even Z and even N are more stable than others due to the pairing effect. Indeed, all nuclei in which double beta-decay is looked for are even-even and this would not be possible were it not for pairing. In MGM's paper on pairing, published shortly after the ones on the magic numbers and role of spin-orbit coupling, she used a very simplified zero range nuclear interaction. There has been considerable work on pairing in the meantime. It is still an open problem how to understand the details of how pairing works in nuclei, in terms of realistic nucleon-nucleon interactions.

  15. Thermal history of crystalline nappes of the Maria fold and thrust belt, west central Arizona

    The thermal history of the crust in west central Arizona, as documented by {sup 40}Ar/{sup 39}Ar step-heating analysis of mineral suites from crystalline nappes of the Maria fold and thrust belt, is characterized by three distinct stages for Late Cretaceous and Tertiary time. Regional heating of the crust occurred during basement-involved folding and thrust faulting in middle Late Cretaceous time and represents the earliest phase recorded by the {sup 40}/{sup 39}Ar data. The second stage was dominated by uplift and slow cooling (5-10C/m.y.) of the crust throughout latest Cretaceous and early Tertiary time. Tectonic denudation in late Oligocene to early Miocene time resulted in rapid uplift and cooling of midcrustal rocks in the footwall of the Whipple-Buckskin-Rawhide detachment system, marking the final thermal signature in the region. Partially outgassed hornblende in the northern Granite Wash Mountains reflects temperatures of {approximately}450C, whereas complete resetting of hornblende at Mesquite Mountain suggests that this area attained temperatures in excess of 500C. In contrast, data from the northern Plomosa Mountains indicate that this area did not attain temperatures sufficient to completely degas biotite or K-feldspar during Late Cretaceous time. Either (1) lower plate rocks were still sufficiently hot following Late Cretaceous heating that argon clocks were set simply due to rapid cooling or (2) the area experienced a renewed thermal input associated with extension, causing argon loss from previously cool rocks. Based on consideration of diffusion domain behavior in K-feldspars, the authors infer that a renewed thermal pulse was associated with the early stages of extension and was related to the cause for crustal weakening.

  16. Origin of tuff deposits in the lower Miocene Lospe Formation, Santa Maria basin, California

    The Lospe Formation contains at least five mappable tuff units (17-18 Ma) which were erupted during initial stages of Neogene Santa Maria basin subsidence. Individual tuff units are lenticular, as much as 15-20 m thick, and 1-3 km wide; they were deposited predominantly in a lacustrine setting. Subaqueous deposition is indicated by facies of the interbedded nonvolcanic Lospe Formation. The lowermost Lospe Tuff unit, however, which overlies Jurassic basement, is interpreted as a subaerial deposit. Each subaqueous tuff unit contains two or more eruption units. Each eruption unit consists of three zones which are, from base to top: (1) massive vitric tuff comprising about 50% of the eruption unit, (2) thin- to medium-bedded vitric tuff with pumice concentrations at the tops of beds and mud drapes between beds, and (3) a thin-bedded interval of massive to planar laminated tuffaceous siltstone-mudstone. The predominance of delicate cuspate vitric shards and pumice, and the near absence of nonvolcanic detritus indicates that little or no reworking of the ash occurred prior to deposition. The Lospe tuffs are predominantly distal pyroclastic flow (zones 1 and 2) and pyroclastic turbidite (zones 2 and 3) deposits, derived from subaerial magmatic eruptions. A possible source for the Lospe tuffs is located at Tranquillon Mountain, 30 km to the south in the westernmost Transverse Range, where 17-18 Ma proximal pyroclastic deposits of welded lithic tuff breccia and thick pumiceous fallout tuffs are present. The similar ages, stratigraphic positions, and petrology, as well as the lateral facies relations suggests a correlation between the Tranquillon volcanic center and the Lospe tuff units. The authors are currently testing this hypothesis on the basis of geochemical and isotopic analyses.

  17. Evidence for fluid flow in ductile shear zones, Granite Wash Mountains, Maria fold and thrust belt

    Synkinematic fluids that accompanied Mesozoic (D2) deformation in the Granite Wash Mountains, eastern Maria fold and thrust belt, had profound effects on the metamorphic mineralogy and deformation mechanisms of Paleozoic metsedimentary rocks. The D2 thrusts are discrete brittle faults that commonly bound highly sheared, ductilely deformed rocks. These low-angle faults cross cut a vertical section of Paleozoic and Mesozoic supracrustal rocks that were multiply repeated and upturned by earlier Mesozoic deformation, D1. Kinematic analysis of a series of these ductile shear zones has confirmed that the dominant sense of motion during thrusting was to the SW, however, some isolated kinematic indicators and indicators along the lowest zone suggest NE-thrusting. Microstructures in samples collected both within D2 ductile shear zones and outside D2 zones show fluids played an important role in D2 deformation. The abundant evidence for fluids along D2 ductile shear zones includes: quartz veins in the Kaibab Fm (a dolomitic marble), zones of metasomatic alteration ( bleached'' zones) within D2 zones, an increase in the abundance of metamorphic minerals within D2 zones, and the presence of synkinematic wollastonite in silicones limestones of the Redwall Fm. The most dramatic and significant effect of synkinematic fluids in on the style of deformation mechanisms operating during thrusting. Evidence for intracrystalline plastic deformation and rotational recrystallization is not well-developed: instead, microstructures are dominated by migrational recrystallization fabrics. In some samples, quartz grain boundaries have migrated over a preexisting foliation defined by aligned micas, indicating that grain boundaries were highly mobile. Fluid-enhanced grain boundary mobility has allowed internally deformed grains or parts of grains to be consumed rapidly with no or little record of the deformation left behind.

    The great meridian line in the Basilica of Santa Maria degli Angeli in Rome was built in 1701/1702 with the scope to measure the Obliquity of the Earth's orbit in the following eight centuries, upon the will of pope Clement XI. During the winter solstice of 1701 the first measurements of the obliquity have been realized by Francesco Bianchini, the astronomer who designed the meridian line, upgrading the similar instrument realized by Giandomenico Cassini in San Petronio, Bononia. In this paper the accuracy of the data observed by Francesco Bianchini is discussed and compared with up-to-date ephemerides. The modern situation of this historical instrument is also presented.

    The musician and composer Maria Theresia Paradis (1759-1824) blind since her earliest childhood was treated in 1777 by the physician Dr. Franz-Anton Mesmer (1734-1815). The treatment he used was the so-called "magnetic therapy". This was a suggestive psychotherapeutical method by which, as he thought, the amaurosis could be cured. The most essential agency of this "magnetic therapy" was music. However, the resistance of both his colleagues and the patient's family forced him to break off the therapy. Maria Theresia Paradis remained blind till the end of her life. The genesis of the amaurosis, the problem of a real therapeutical influence by Mesmer and, especially, the relationship between the music as a therapeutical medium and the musical personality of the patient are discussed in detail. The whole care cannot be cleared up definitively. There are many indications that Mesmer succeeded in improving temporarily a hysterical amaurosis of Maria Theresia Paradis. PMID:1960933

It is the record of incoming patients of one for the main hospitals of the city, devoted exclusively to the sick poor and not just to the poor, called Santa Maria della Morte, compiled by a young student assistant (astante) for the period 1558-1564. I publish here a transcription of a portion of this Libro pertaining to the year 1560.

    Stratigraphic information from 694 oil and gas exploration wells from the onshore Santa Maria basin and surrounding areas are herein compiled in digital form from reports that were released originally in paper form. The Santa Maria basin is located within the southwesternmost part of the Coast Ranges and north of the western Transverse Ranges on the central California coast. Knowledge of the location and elevation of stratigraphic tops of formations throughout the basin is a first step toward understanding depositional trends and the structural evolution of the basin through time.

    The Mastcam imaging system on the Curiosity rover continued acquisition of multispectral images of the same terrain at multiple times of day at three new rover locations between sols 872 and 1003. These data sets will be used to investigate the light scattering properties of rocks and soils along the Curiosity traverse using radiative transfer models. Images were acquired by the Mastcam-34 (M-34) camera on Sols 872-892 at 8 times of day (Mojave drill location), Sols 914-917 (Telegraph Peak drill location) at 9 times of day, and Sols 1000-1003 at 8 times of day (Stimson-Murray Formation contact near Marias Pass). Data sets were acquired using filters centered at 445, 527, 751, and 1012 nm, and the images were jpeg-compressed. Data sets typically were pointed ~east and ~west to provide phase angle coverage from near 0° to 125-140° for a variety of rocks and soils. Also acquired on Sols 917-918 at the Telegraph Peak site was a multiple time-of-day Mastcam sequence pointed southeast using only the broadband Bayer filters that provided losslessly compressed images with phase angles ~55-129°. Navcam stereo images were also acquired with each data set to provide broadband photometry and terrain measurements for computing surface normals and local incidence and emission angles used in photometric modeling. On Sol 1028, the MAHLI camera was used as a goniometer to acquire images at 20 arm positions, all centered at the same location within the work volume from a near-constant distance of 85 cm from the surface. Although this experiment was run at only one time of day (~15:30 LTST), it provided phase angle coverage from ~30° to ~111°. The terrain included the contact between the uppermost portion of the Murray Formation and the Stimson sandstones, and was the first acquisition of both Mastcam and MALHI photometry images at the same rover location. The MAHLI images also allowed construction of a 3D shape model of the Stimson-Murray contact region. The attached figure

    Since her shipwreck in 1771, the wooden vessel Vrouw Maria has been lying on the seabed at 41 m depth on the border between the Archipelago Sea and the northern Baltic proper, off the southern coast of Finland. The wreck lies in an upward position in a right angle to the dominating bottom current, which is potentially affecting seabed topography, sediment characteristics and zoobenthic communities both upstream (NE) and downstream (SW) of the wreck. This multidisciplinary study attempts to clarify abiotic and biotic patterns and processes in the vicinity of the wreck by combining field investigations with physical simulation studies in the field and in the laboratory. Multibeam echo-sounder techniques were utilised to generate a map of the wreck area and sediment grab samples were taken to characterize the sediment type and its zoobenthic community. A medium-sized field experiment generated data on the accumulation of sediment organic matter in the presence and absence of a current and/or a barrier on the seafloor and a small-scaled laboratory study was conducted to simulate scour forming processes. The results showed that a deeper basin, scour area, with the dimensions 150×300 m, was present downstream of the wreck and there was also a smaller scour area upstream of the wreck. Similar traces on the bottom were simulated in the laboratory. The organic content (recent mud) and the proportion of finer sediment were more pronounced in areas closer to both sides of the wreck. These results were in turn imitated in a field experiment, where the accumulation of organic matter in the sediment increased significantly downstream, when a current was interrupted by a barrier. Regarding zoobenthos in the wreck area, 11 taxa and a mean total abundance of 773 individuals per m2 were registered. The dominant species were Macoma balthica and Marenzelleria sp., which together made up >80% of the total number of individuals. Multivariate data analyses showed significant differences

  10. The emergence and evolution of Santa Maria Island (Azores) - the conundrum of uplifting islands revisited

    The growth and decay of ocean island volcanoes is intrinsically linked to vertical movements; whilst mechanisms for subsidence are well understood, uplift mechanisms are still very enigmatic. Santa Maria Island in the Azores is an ocean island volcano with a complex evolutionary history with subsidence followed by uplift. The island emerged by surtseyan activity at approximately 6 Ma, entailing in the formation of a subaerial shield volcano that was fully developed by ~5.6 Ma. The edifice then experienced a period of intense erosion and subsidence, during which it was partially or completely truncated to a shallow submarine bank. Around 5 Ma, volcanism resumed on the eastern side of the edifice, with occasional submarine/surtseyan activity synchronous with marine deposition. By ~4.3 Ma, volcanism grew in intensity forming a new edifice centred on the eastern flank of the underlying edifice. This new volcanic edifice started as submarine and then, as it gradually grew upwards and outpaced subsidence, breached sea level and formed a new island. The new edifice kept growing eastwards and northwards until ~3.5 Ma, when volcanic activity waned. At 3.5-3.2 Ma, however, subsidence reversed to an uplift trend that extended throughout the Upper Pleistocene into the present. This uplift trend is responsible for the generation of a staircase of shore platforms on the windward side of the island, which extends up to ~230 m in elevation. The fact that an island located in very young lithosphere experienced such a pronounced uplift trend is remarkable and raises important questions concerning possible uplift mechanisms. The loading of the neighbouring island of São Miguel may account for part of the uplift, but not the majority. Vertical tectonics along the nearby Gloria Fault is not completely implausible but unlikely to be a source of significant uplift due to its dominant strike-slip character. Thus, other mechanisms need to be considered, most notably intrusions at the base

    This research was conducted in Porto Alegre, Rio Grande do Sul, with a sample of battered women selected from a government shelter called the "Casa Viva Maria". We analyzed data on 110 women staying at the shelter during the previous two years (January 1996-June 1998). The profile of the women was as follows: abused women were young (mean age 29 years), all had low socioeconomic status, 12% were illiterate, 21% were black, 80% reported frequent abuse by their partners, and 18% had returned to violent homes. The researchers visited 34 former lodgers from the shelter and invited them to participate in a series of evaluation workshops. A total of 118 persons, including mothers and children, attended three evaluation meetings. During this process, researchers encouraged participants to express opinions, perceptions, and feelings about their past experience in the shelter and their own concept of violence. Finally, a focal group was organized with the "Viva Maria" staff members. Female workers reported how their job had been helpful for their personal development and had helped change their own lives.

    The southern region of Islas Marias, in front of Bahía de Banderas (21.20,-106.80; 20.26, -106.05), is characterized by a low magnitude seismicity as recorded in both international and national catalogues. However due to the lack of coverage by the seismic stations in the region only a few records exist. It is assumed that the seismicity results from the subduction effect of the Rivera Plate with the Jalisco Block. The Accelerometric Seismic Network of Jalisco (RESAJ) has recorded the events of September 14th 2012 Mw=5.6 and the event of the first of the month Mw=4.9 and 27 more events. Because of this evidence, along with the history of the earthquake of M=7.0 on December third 1948 in Islas Marias, which almost destroyed the penal colony, it is important to study the seismicity of the area given the potential risk that this represent for the populations nearby. The RESAJ data also includes three groups of earthquakes detected in last months of December and November 2012, and the earthquake on Wednesday January 23th 2013, along with their characteristic group. Here, we present the first part of a study of the seismicity of the area using the RESAJ records. By analyzing the aforementioned data it is shown that seismicity of the zone occurs by clusters.

    A total of 112 specimens of yellow peacock bass, Cichla kelberi, were collected in the Três Marias Reservoir, upper São Francisco River, State of Minas Gerais, between 2004 and 2005. Twelve species of parasites were collected: two species of ectoparasites (the monogenetic Gussevia sp. and the copepod Ergasilus sp.); and ten species of endoparasites, including four species of adult endoparasites: the cestodes Proteocephalus macrophallus and P. microscopicus, and the nematodes: Capillostrongyloides sentinosa and Rhabdochona acuminata, and six species of larval endoparasites: the metacercariae of Austrodiplostomum compactum and the nematodes: Hysterothylacium sp., Contracaecum sp. Type 1, Procamallanus (Spirocamallanus) inopinatus, Spiroxys sp., and Goezia sp.. A significant positive correlation in the abundance of the two adult endoparasites species, P. macrophallus and P. microscopicus, may indicate that such associated species had the same ecological requirements. The positive correlations between the prevalence of the larval endoparasites, Hysterothylacium sp. and A. compactum, may indicate that there was opportunism for the two generalists species. Ergasilus sp., C. sentinosa, R. acuminata and Hysterothylacium sp. were recorded for the first time in C. kelberi, and this increased their list of known hosts. In addition, both proteocephalid species and C. sentinosa can extend their known biogeographical distribution to the Três Marias Reservoir.

    Foraminifera and diatoms have been analyzed from an upper Miocene through Pleistocene(?) sequence of marine sediments exposed on Maria Madre Island, largest of the Tre??s Marias Islands off the Pacific coast of Mexico. The Neogene stratigraphic sequence exposed on Maria Madre Island includes a mid-Miocene(?) non-marine and/or shallow marine sandstone unconformably overlain by a lower upper Miocene to uppermost Miocene upper to middle bathyal laminated and massive diatomite, mudstone, and siltstone unit. This unit is unconformably overlain by lower Pliocene middle to lower bathyal sandstones and siltstones which, in turn, are unconformably overlain by upper Pliocene through Pleistocene(?) upper bathyal to upper middle bathyal foraminiferal limestones and siltstones. These beds are unconformably capped by Pleistocene terrace deposits. Basement rocks on the island include Cretaceous granite and granodiorite, and Tertiary(?) andesites and rhyolites. The upper Miocene diatomaceous unit contains a low diversity foraminiferal fauna dominated by species of Bolivina indicating low oxygen conditions in the proto-Gulf Maria Madre basin. The diatomaceous unit grades into a mudstone that contains a latest Miocene upper to middle bathyal biofacies characterized by Baggina californica and Uvigerina hootsi along with displaced neritic taxa. An angular unconformity separates the upper Miocene middle bathyal sediments from overlying lower Pliocene siltstones and mudstones that contain a middle to lower bathyal biofacies and abundant planktonic species including Neogloboquadrina acostaensis and Pulleniatina primalis indicating an early Pliocene age. Significantly, this Pliocene unit contains common occurrences of benthic species restricted to Miocene sediments in California including Bulimina uvigerinaformis. Pliocene to Pleistocene(?) foraminiferal limestones and siltstones characterize submarine bank accumulations formed during uplift of the Tre??s Marias Island area, and include

    The Hosgri Fault Zone trends subparallel to the south-central California coast for 110 km from north of Point Estero to south of Purisima Point and forms the eastern margin of the present offshore Santa Maria Basin. Knowledge of the attributes of the Hosgri Fault Zone is important for petroleum development, seismic engineering, and environmental planning in the region. Because it lies offshore along its entire reach, our characterizations of the Hosgri Fault Zone and adjacent structures are primarily based on the analysis of over 10,000 km of common-depth-point marine seismic reflection data collected from a 5,000-km2 area of the central and eastern parts of the offshore Santa Maria Basin. We describe and illustrate the along-strike and downdip geometry of the Hosgri Fault Zone over its entire length and provide examples of interpreted seismic reflection records and a map of the structural trends of the fault zone and adjacent structures in the eastern offshore Santa Maria Basin. The seismic data are integrated with offshore well and seafloor geologic data to describe the age and seismic appearance of offshore geologic units and marker horizons. We develop a basin-wide seismic velocity model for depth conversions and map three major unconformities along the eastern offshore Santa Maria Basin. Accompanying plates include maps that are also presented as figures in the report. Appendix A provides microfossil data from selected wells and appendix B includes uninterpreted copies of the annotated seismic record sections illustrated in the chapter. Features of the Hosgri Fault Zone documented in this investigation are suggestive of both lateral and reverse slip. Characteristics indicative of lateral slip include (1) the linear to curvilinear character of the mapped trace of the fault zone, (2) changes in structural trend along and across the fault zone that diminish in magnitude toward the ends of the fault zone, (3) localized compressional and extensional structures

    The use of LANDSAT multispectral ban scanner imagery to verify the relationship between the behavior of the Tres Marias reservoir and the dynamics of the Sao Francisco River supply basin is described. The dispersion of suspended sediments and their concentration in the surface layers of the water are considered. A five year survey of the region during both dry and rainy seasons was performed. The drainage network was analyzed based on the patterns of dessication, water rises and soil use in the supply basin. Surface layers of the reservoir were tabulated as a function of the levels of gray in the imagery. In situ observations of water depth and reflectance were performed. Ground truth and LANDSAT data were correlated to determine the factors affecting the dynamics of the supply basin.

    Obesity and osteoporosis are chronic disorders with increasing prevalence worldwide. The aim of this study was to investigate the association between obesity and fracture in postmenopausal women from Santa Maria, Brazil. A cross-sectional study was carried out at Santa Maria (parallel 29° south), Brazil. Postmenopausal women aged ≥55 yr who had at least 1 appointment at the primary care in the 2 years before the study were recruited from March 1, 2013 to August 31, 2013. The Global Longitudinal Study of Osteoporosis in Women study questionnaire was applied with permission of The Center for Outcomes Research, University of Massachusetts Medical School. Height and weight were measured according to the World Health Organization protocol. Bone fractures (excluding hand, feet, and head) that occurred after the age of 45 yr were considered as the outcome. Overall, 1057 women completed the study, of whom 984 had body mass index measured. The mean (standard deviation) age and body mass index of the women included in the study were 67.1 (7.6) yr and 29.2 (5.5) kg/m(2), respectively. The prevalence of fractures in obese and nonobese women was similar (17.3% vs 16.0%); 41.4% of all fractures occurred in obese women. Obese postmenopausal women make a substantial contribution to the overall burden of prevalent fractures in this population. Our results provide further evidence in support of the concept that obesity is not protective against fracture. PMID:25534276

  20. Accumulation rates of biogenous silica and terrigenous detritus in late Miocene-early Pliocene Santa Maria basin, California

    1988-03-01

    The upper-Miocene-lower Pliocene laminated to massive diatomaceous strata of the Santa Maria basin encompass portions of the Monterey and overlying conformable to nonconformable Sisquoc Formations and record the continued accumulation of admixed siliceous (mostly diatoms) and terrigenous (silt and clay) components in a Neogene borderland basin. Lithologies, which vary from diatomite to diatomaceous mudstone, are the result of fluctuations in slope-accumulating silica and terrigenous debris. Bulk accumulation rates, as well as silica and terrigenous component accumulation rates, were calculated for four measured sections using accurate stratal thicknesses, absolute ages, rock compositions, and bulk densities. Bulk accumulation rates range from less than 20 to greater than 70 mg/cm/sup 2//year and are comparable to bulk accumulation rates in the present-day Santa Barbara basin and Gulf o f California. Silica accumulation rates (20-30 mg/cm/sup 2//year) suggest that sedimentation took place beneath productive waters and they exceed those encountered in other high-productivity oceanic areas, such as the Bering Sea and Peruvian coastal waters. Relatively high terrigenous accumulation rates (18-35 mg/cm/sup 2//year) reflect the dilution of these high-productivity waters by continentally derived detritus. Comparison of calculated accumulation rates with rates determined for similarly aged strata of the Santa Barbara basin reveals that silica and terrigenous debris were accumulating at higher rates within the Santa Maria basin. These differences are due to the complex interplay of tectonics and oceanographics and to the proximity of the basins relative to the strandline.

Subsequently Willis was summoned to Lisbon to advise on the mental health problems of Queen Maria I. This article reports the nature of the illnesses of Maria and her two similarly affected sisters, and uses the program OPCRIT to propose diagnoses of major depressive disorders. The high prevalence of consanguinity and insanity among the Portuguese monarchy and their antecedents probably contributed to their mental health problems. The successive contributions of the Willis family from Thomas Willis (1621-75) to his grand-nephew, Francis Willis (1792-1859), are reviewed; the popular image is somewhat inaccurate and does not highlight their part in the development of psychiatry.

    This paper describes new ginkgophytes recently discovered in a new exposure of the original type section of the Passo das Tropas Member, Santa Maria Formation, linked to Paraná Basin succession. The well-preserved fossils come from a very fine red laminated mudstone representing a lacustrine interval, within a broader low-sinuosity fluvial succession. The material occurs in a Dicroidium-dominated assemblage and is represented by the leaves Baiera and Sphenobaiera, accompanied by the fertile structures Hamshawvia and Stachyopytis. Cuticle fragments preserved on leaf impressions of Sphenobaiera schenkii show xeromorphic features. The geology, paleogeography and paleoclimate of the Passo das Tropas Member (PTM), Santa Maria Formation, is discussed. By comparing these ginkgophytes with those from other Gondwanan assemblages, the Brazilian deposits earlier assigned to Anisian-Ladinian age can now be extended to the Carnian age.

    During the Turkish University Reform in 1933 the Turkish Government invited many foreign scientists in order to assign them to Istanbul University. Almost all of them were scientists who had escaped from Hitler's Germany. In 1938, also some Austrian scientists who had to leave their country were included into the staff of Istanbul University. Dr. Rosa Maria Rössler, born in Vienna in 1901, came to Turkey in 1934, earlier than the other Austrians did. She worked in the Institute of Pathologic Anatomy of the Medical Faculty of Istanbul University permanently from 1937 under Prof. Dr. Philipp Schwartz; after ten years she moved to the 2(nd) Clinic for Internal Diseases under Prof. Dr. Erich Frank, in the same faculty.

    Two holy water fonts (dated at the beginning of the XVII century) in the Santa Maria della Steccata Church in Parma (Italy) have recently been restored. Before the intervention, a detailed investigation on their degradation products was carried out to understand the mechanisms of alteration of the materials and to suggest appropriate restoration procedures. The analyses were performed by means of powder X-ray diffraction (XRD), micro-Fourier transform infrared (FTIR) and micro-Raman spectroscopies. Calcite, iron oxides, silicates and sodium chloride (from salted holy water) were found in the red coloured calcarenite. On and under the lead coverings, different lead oxides (mainly massicot), other lead salts (lead basic carbonate, cerussite, plumbonacrite Pb10O(OH)6(CO3)6 and lead-chlorine compounds as laurionite PbOHCl and phosgenite Pb2CO3Cl2) were identified by Raman spectroscopy and XRD. Haematite alpha-Fe2O3, goethite alpha-FeO(OH) and lepidocrocite gamma-FeO(OH) were found on and around the iron hinges. Lead compounds and sodium chloride, through crystallization and solubilization cycles, were responsible for the stone's degradation, whereas the iron corrosion materials on the hinges produced mechanical stress and cracks in the stone. Various suggestions have been given on how to restore these fonts and to remove the causes of damage.

    This study focuses on the carbonate biodegradation processes of deep-water scleractinians from off Apulia at Santa Maria di Leuca (SML) in the Ionian Sea, including living colonies of Lophelia pertusa, Madrepora oculata and Desmophyllum dianthus. The corallites were grouped into three zones: the live zone, edge zone and dead zone. In total, 13 trace types were encountered and are attributed to borings of sponges (3), fungi (6), foraminifers (2), bacteria (1) and annelids (1). Their relative spatial appearance within the host skeletons led to the distinction between six succession stages of bioerosion. The first endobiontic traces are exclusively produced by bacteria and fungi and are already present in the edge zone, which could be attributed to their fast growth rates and/or temporal exposure of the bare skeleton to the water column. In D. dianthus the entire ichnospecies assemblage has been documented within the first 1.9 cm below the live zone and represents the most condensed bioerosion succession amongst the coral species studied. The strongest degradation of corallites at SML is made by boring sponges, which can excavate 70% or more of the skeleton. The finding of a unilateral condensed succession of bioerosion stages may be linked to prevailing unidirectional strong currents. A comparison of the present ichnocoenosis with bioerosion studies from the Eastern Atlantic evidences a reduced ichnodiversity in Ionian Sea bathyal corals.

    On January 2013, a disaster at Santa Maria (RS) due to a fire in a confined space caused 242 deaths, most of them by inhalation injury. On November 2013, four individuals required intensive care following smoke inhalation from a fire at the Memorial da América Latina in São Paulo (SP). The present article reports the clinical progression and management of disaster victims presenting with inhalation injury. Patients ERL and OC exhibited early respiratory failure, bronchial aspiration of carbonaceous material, and carbon monoxide poisoning. Ventilation support was performed with 100% oxygen, the aspirated material was removed by bronchoscopy, and cyanide poisoning was empirically treated with sodium nitrite and sodium thiosulfate. Patient RP initially exhibited cough and retrosternal burning and subsequently progressed to respiratory failure due to upper airway swelling and early-onset pulmonary infection, which were treated with protective ventilation and antimicrobial agents. This patient was extubated following improvement of edema on bronchoscopy. Patient MA, an asthmatic, exhibited carbon monoxide poisoning and bronchospasm and was treated with normobaric hyperoxia,bronchodilators, and corticosteroids. The length of stay in the intensive care unit varied from four to 10 days, and all four patients exhibited satisfactory functional recovery. To conclude, inhalation injury has a preponderant role in fires in confined spaces. Invasive ventilation should not be delayed in cases with significant airway swelling. Hyperoxia should be induced early asa therapeutic means against carbon monoxide poisoning, in addition to empiric pharmacological treatment in suspected cases of cyanide poisoning. PMID:25607274

    Thanatofacies and the skeletonized components of the living facies, from which they originate have been studied from the Santa Maria di Leuca (SML) deep-water coral mound province. Faunal analysis was carried out by means of bottom sampling and underwater video observations, taking into account all benthic taxonomic groups, mostly corals, molluscs, serpulids, bryozoans, ostracods, foraminifers and barnacles, which permitted recognition of six different facies. These thanatofacies are easily distinguishable and appear to be largely corresponding and overlapping with related living facies. Some occur in mound areas, others in the intermound ones. They are as follows: the Framework-building Coral facies (FC), characterised by colonial corals, mostly Madrepora oculata; the Coral Rubble facies (CR), with proximal and distal aspects, characterised by large- to small-sized and densely to loosely packed coral fragments; the Solitary Coral facies (SC), dominated by different species depending on the availability and dimensions of hard exploitable surfaces; the Gryphus and Isidella facies (GI) in relatively coarse-grained bottoms; the Mollusc Mud facies (MM) and the Foraminifer Mud facies (FM) in comparably homogeneous silty bottoms. Facies distribution and spatial variability are discussed, in relation to hydrology and sea-floor topography. Furthermore, the SML facies are compared with living facies from the present-day Mediterranean and Pleistocene sediments of the same area. Data on bioclastic assemblages can serve for comparison with other recent aphotic, non-tropical carbonates.

    U-Pb dating of zircon was undertaken with the Beijing SHRIMP II (sensitive high resolution ion microprobe) on anamphibolite facies granodiorite and an almandine-albite granulite from the Santa Maria Chico Granulitic Complex, southern Brazilian Shield. This work was also done to unravel protolith ages which are often hidden in the array of partly reset data. The obtained metamorphic ages of the granodiorite gneiss and the granulite are 2035 +/- 9 Ma and 2006 +/- 3 Ma, respectively. These data are within the range of metamorphic ages determined in previous studies (2022 +/- 18 Ma and 2031 +/- 40 Ma). However, protolith ages for the granodiorite (2366 +/- 8 Ma) and the granulite (2489 +/- 6 Ma) were obtained which are outside the previously recognized range (> 2510-2555 Ma). The magmatic protolith age of the granodiorite refers to a previously little known magmatic event in the shield. Further investigations may demonstrate that amphibolite facies zircon crystals are useful as a window into geological events in associated granulites, because zircon ages are blurred in the studied granulites.

    The aim of the study was to characterize specimens submitted to the effects of weathering in an urban atmosphere. Samples investigated were stones covered by crusts and deposits of thickness ranging from micrometers to millimetres due to traffic pollutants and mineral dust. The pieces were collected in the Church of Santa Maria La Blanca in Seville (South Spain). In the Historical Centre of this city, the traffic is the main source of sulphur oxides. Several analytical techniques have been employed to determine composition of specimens: OM, XRD, XRF, SEM-EDX and LIBS. The main weathering form was gypsum (CaSO4ṡ2H2O), and it has its source in sulphur oxides from traffic. Over this alteration layer, the deposits of atmospheric particles have been found. According to LIBS results, these particles can be composed of Al, Si, Ba, K, Na, Ti, V, Mg and Ca, while XRF technique also detect S, Fe, Mn and P. These atmospheric particles can have an anthropogenic or terrigenous origin, including the weathering of the building materials and its restoration products.

    Marie Curie, née Maria Sklodowska, was born on November 7, 1867 in Warsaw (Poland). She suffered from leukaemia and died on June 4, 1934. She was buried with full honours at Pantheon. Marie Curie and her husband Pierre Curie discovered the radioactive elements Polonium (84Po210), Thorium (90Th232) and Radium (88Ra226). Marie Curie introduced the term radioactivity into science. She was the first woman who got Ph.D. in France, the first woman professor at Sorbonne, Paris and Medical Academy. Of all the women who have ever won the Nobel Prize, Marie Curie was the only who received it twice. During World War I Marie Curie designed a mobile x-ray room "radiologic car". Marie Curie had an x-ray machine installed into a car and demonstrated how to use its dynamo for electric power production necessary for the x-ray machine to work. She had 20 cars with moving radiological lab made and trained 150 people to work on them. She brought something radically new into military medicine--mobile x-ray diagnostics. With the discovery of radioactive elements a new medical branch, radiotherapy, was developed.

    The privileged location of Santa Maria Island (Azores archipelago) in the middle of the North Atlantic makes the fossiliferous outcrops on this island of utmost importance to gain a better understanding of how coeval living communities relate to the broader evolutionary and biogeographic history of the Atlantic basin during the late Neogene and the Quaternary. Here we focus on this island's MIS 5e fossil record, offering a comprehensive review on the palaeobiodiversity, palaeoecology and palaeobiogeography of the biota living in the mid North Atlantic during this interglacial. Several studies in oceanic islands stress the huge impact of sea level changes on insular communities. Pleistocene sea-level changes occur during the short-time events known as "Terminations" (associated to glacial/interglacial shifts) as well as with the onset of glaciations (associated to interglacial/glacial shifts). Both are responsible for extinctions and local disappearance of species, bottleneck effects and formation of new species, resulting in community structure changes. This work increases the number of fossil marine taxa reported from the Last Interglacial deposits of Santa Maria to 143 species. All the 19 new records are molluscs (13 gastropods and 6 bivalves), thus increasing the number of fossil molluscs to 136 species. Although thermophilic members of the "Senegalese" tropical fauna were found in these deposits, many of the most emblematic species (e.g., Persististrombus latus (=Strombus bubonius), Cymbula safiana, Harpa doris, Cardita senegalensis, Barbatia plicata, Ctena eburnea or Hyotissa hyotis) are absent, suggesting that they did not reach the Azores. Our results indicate that the main differences between the species composition of the MIS 5e and the present-day shallow-water Azorean communities are probably due to the dropping of sea surface temperature associated with the onset of the last glaciation, which had both direct and indirect effects on species ecology.

    Within the Oceanic-West Huasna fault system of western San Luis Obispo County, thick bathyal mudstone records abrupt early Miocene subsidence. Lower Miocene rocks west of the fault, in contrast, suggest a relative high. Between fault splays, {le} 1,800 ft of mudstone (Rincon Formation) contains Saucesian lower bathyal foraminifera and CN2-CN1c ({approximately} 17-21 Ma) nannofossils. The mudstone was deposited on a subsiding erosional surface cut on Great Valley and Franciscan basement overlain locally by late Oligocene rhyodacite (Cambria Felsite), nonmarine conglomerate (Lospe Formation), and nearshore sandstone (Vaqueros Formation). Basinal late early to middle Miocene Obispo and Monterey formations overlie the older mudstone. West of the fault, major subsidence does not conclusively predate {approximately} 17 Ma submarine Obispo tuff. Northeast of Morro Bay, nearshore Vaqueros underlies Obispo or Monterey formations. Northeast of Santa Maria, Franciscan rocks are overlain by thin nonmarine conglomerate, sandstone with upper bathyal Saucesian foraminifera and upper CN2 nannofossils, and Obispo volcanics. Near Cambria, nonmarine conglomerate and Vaqueros sandstone were deposited on the Franciscan between {approximately} 27-27 Ma (Cambria Felsite) and 25 Ma ({sup 87}Sr/{sup 86}Sr on Vaqueros shells); only {approximately}100 ft of basinal mudstone separates Vaqueros from obispo tuff. In the Pismo syncline, the Franciscan was near sea level 25 Ma ({sup 87}Sr/{sup 86}Sr or shells); subsidence to bathyal depths cannot be demonstrated until just before Obispo eruption. Paleobathymetric estimates suggest initiation of at least 6,000 ft of subsidence along the fault system {approximately} 20-21 Ma. The block to the west, in contrast, either stayed high, or subsided but was uplifted and stripped, subsiding again as Obispo eruption began. The authors have not found evidence for major lateral offset on this fault.

    We used borehole televiewer (BHTV) data from four wells within the onshore and offshore Santa Maria basin, California, to investigate the relationships among fracture distribution, orientation, and variation with depth and in-situ stress. Our analysis of stress-induced well-bore breakouts shows a uniform northeast maximum horizontal stress (SH max) orientation in each well. This direction is consistent with the SH max direction determined from well-bore breakouts in other wells in this region, the northwest trend of active fold axes, and kinematic inversion of nearby earthquake focal plane mechanisms. In contrast to the uniformity of the stress field, fracture orientation, dip, and frequency vary considerably from well to well and within each well. With depth, fractures can be divided into distinct subsets on the basis of fracture frequency and orientation, which correlate with changes of lithology and physical properties. Although factors such as tectonic history, diagenesis, and structural variations obviously have influenced fracture distribution, integration of the in-situ stress and fracture data sets indicates that many of the fractures, faults, and bedding planes are active, small-scale strike-slip and reverse faults in the current northeast-trending transpressive stress field. In fact, we observed local breakout rotations in the wells, providing kinematic evidence for recent shear motion along fracture and bedding-parallel planes. Only in the onshore well do steeply dipping fractures strike parallel to SHmax. Drill-stem tests from two of the offshore wells indicate that formation permeability is greatly enhanced in sections of the wells where fractures are favorably oriented for shear failure in the modern stress field. Thus, relatively small-scale active faults provide important conduits along which fluids migrate.

    Zinc plant purification residue (ZPR), a typical Zn-hydrometallurgical waste, was collected from the Três Marias Zn plant (MG, Brazil). ZPR was characterized for its metal content and fractionation, mineralogy, toxicity and leachability. Toxicity characteristics leaching procedure (TCLP) and European Community Bureau of Reference (BCR) sequential extraction results revealed that this ZPR displays high percentages of metals (Cd, Cu, Zn and Pb) in the highly mobilizable fractions, increasing its hazardous potential. Bulk chemical analysis, pH dependent leaching and acid (H2SO4) leaching studies confirm that the ZPR is polymetallic, rich in Cd, Cu and Zn. The sulfuric acid concentration (1 M), agitation speed (450 rpm), temperature (40 °C) and pulp density (20 g L(-1)) were optimized to leach the maximum amount of heavy metals (Cd, Cu and Zn). Under optimum conditions, more than 50%, 70% and 60% of the total Cd, Cu and Zn present in the ZPR can be leached, respectively. The metals in the acid leachates were investigated for metal sulfide precipitation with an emphasis on selective Cu recovery. Metal sulfide precipitation process parameters such as initial pH and Cu to sulfide ratio were optimized as pH 1.5 and 1:0.5 (Cu:sulfide) mass ratio, respectively. Under optimum conditions, more than 95% of Cu can be selectively recovered from the polymetallic ZPR leachates. The Cu precipitates characterization studies reveal that they are approximately 0.1 μm in diameter and mainly consist of Cu and S. XRD analysis showed covellite (CuS), chalcanthite (CuSO4·5H2O) and natrochalcite (NaCu2(SO4)2(OH)·H2O) as the mineral phases. ZPRs can thus be considered as an alternative resource for copper production. PMID:27074201

    The MARIA reactor at the Institute of Atomic Energy (IAE) in Swierk (30 km SE of Warsaw) in the Republic of Poland is considering conversion from high-enriched uranium (HEU) to low-enriched uranium (LEU) fuel assemblies (FA). The FA design in MARIA is rather unique; a suitable LEU FA has never been designed or tested. IAE has contracted with CERCA (the fuel supply portion of AREVA in France) to supply 2 lead test assemblies (LTA). The LTAs will be irradiated in MARIA to burnup level of at least 40% for both LTAs and to 60% for one LTA. IAE may decide to purchase additional LEU FAs for a full core conversion after the test irradiation. The Reactor Safety Committee within IAE and the National Atomic Energy Agency in Poland (PAA) must approve the LTA irradiation process. The approval will be based, in part, on IAE submitting revisions to portions of the Safety Analysis Report (SAR) which are affected by the insertion of the LTAs. (A similar process will be required for the full core conversion to LEU fuel.) The analysis required was established during working meetings between Argonne National Laboratory (ANL) and IAE staff during August 2006, subsequent email correspondence, and subsequent staff visits. The analysis needs to consider the current high-enriched uranium (HEU) core and 4 core configurations containing 1 and 2 LEU LTAs in various core positions. Calculations have been performed at ANL in support of the LTA irradiation. These calculations are summarized in this report and include criticality, burn-up, neutronics parameters, steady-state thermal hydraulics, and postulated transients. These calculations have been performed at the request of the IAE staff, who are performing similar calculations to be used in their SAR amendment submittal to the PAA. The ANL analysis has been performed independently from that being performed by IAE and should only be used as one step in the verification process.

  20. Effects of a 2006 High-Flow Release from Tiber Dam on Channel Morphology at Selected Sites on the Marias River, Montana

    In June 2006, an opportunistic high-flow release was made from Tiber Dam on the Marias River in Mont., to investigate possible alternatives for partially restoring the river's natural flow pattern and variability. At two sites along the river, we measured channel geometry before and after the high-flow release to evaluate channel change and alteration of physical habitat. Streamflow downstream from Tiber Dam has been stabilized by reduction of high flows and augmentation of low flows. This has produced flood-control benefits as well as some possible adverse environmental effects downstream from the dam. The 2006 high-flow release resulted in a downstream hydrograph with high flows of above-average magnitude in the post-dam flow regime of the Marias River. Timing of the peak and the declining limb of the release hydrograph were very similar to a historical, unregulated hydrograph of the Marias River. Furthermore, the high flow produced many of the qualitative elements of ecologically important physical processes that can be diminished or lost due to flow stabilization downstream from a dam. Typically dry back channels were occupied by flowing water. Islands were inundated, resulting in vegetation removal and sediment accretion that produced new disturbance patches of bare, moist substrate. Cut banks were eroded, and large woody debris was added to the river and redistributed. Flood-plain surfaces were inundated, producing substantial increases in wetted perimeter and spatially distinctive patterns of deposition associated with natural levee formation. The scale of the 2006 high flow - in terms of peak magnitude and the lateral extent of bottomland influenced by inundation or lateral channel movement - was roughly an order of magnitude smaller than the scale of an infrequent high flow in the pre-dam regime. Overall extent and composition of riparian vegetation will continue to change under a scaled-down, post-dam flow regime. For example, the importance of the non

    Since landing in August 2012, DAN has provided a wealth of scientific data from the successful surface operation in both Active mode and Passive mode. The main scientific objectives of DAN are twofold. The primary objective is to measure the bulk hydrogen abundance (in forms of water or hydrated minerals) of the subsurface. The secondary objective is to measure the background neutron environment at the surface. DAN achieves the first objective by using the pulsed neutron generator (PNG) as a pulsed 14 MeV neutron source (active mode). When no neutron pulse is used (passive mode), DAN measures the neutron background environment at the Martian surface. The DAN active data have extensively and successfully used in estimating the near-surface contents of hydrogen (in terms of "water equivalent hydrogen" or WEH) and chlorine (in terms of "absorption equivalent chlorine" or AEC) at multiple locations in Gale crater. In the mean time, DAN has been accumulating the passive mode data in almost all sols since landing, and it is the main topic of this presentation. Particularly, we want to show the DAN data on Sol 991 and 992 where we observed very high passive thermal neutron count - a factor of ~2 higher than usual count. As a reminder, note that many different factors would influence the amplitude of DAN passive thermal neutron counts - GCR condition, soil compositions, water/chlorine contents, etc. The Sol 991/992 location, which is at a region near a rock target called Elk in Marias Pass, was also analyzed by another MSL instrument ChemCAM. And interestingly, its data show that the Elk target is estimated to contain as high as 80 wt% of SiO2, which is radically different from what we have used as a reference soil composition for the interpretation of the DAN passive data. This means that the DAN passive data simulations have to be revisited to account for different soil composition data at the Elk target region. In the final presentation, we will present new simulation

    Thirty-three sediment samples were collected from the Santa Maria La Reforma coastal lagoon and digested by way of a strong acid mixture and sequential arsenic (As)-extraction method to determine the arsenic (As) content and bioavailability. The As content was determined by atomic fluorescence spectrometry. In addition, grain-size analyses were performed, and organic carbon, carbonate, and iron (Fe) and manganese (Mn) concentrations were determined. Fe and Mn determination was performed by atomic absorption spectroscopy. A Pearson correlation matrix and As enrichment factors were calculated. Sediment concentrations from Santa Maria La Reforma ranged from 3.6 to 25 µg As g(-1) with an average of 13.4 ± 7.6 µg As g(-1). The highest values were observed in the northern (Playa Colorada), north-central (Mocorito River discharge zone), and southern zones ("El Tule" agricultural drain). Most samples were classified as exhibiting no or minor As enrichment and were lower than the threshold effect level (TEL; 7.24 µg g(-1)) for biota (MacDonald et al. in Ecotoxicology 5:253-278, 1996). Low bioavailable As values (<3 %) were measured in the majority of the sediment. The highest As percentages were associated with the oxyhydroxide fraction (F5). The results indicate that As bioavailability is negligible. PMID:26743199

    Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzymopathy in the world. More than 160 mutations causing the disease have been identified, but only 10% of these variants have been studied at biochemical and biophysical levels. In this study we report on the functional and structural characterization of three naturally occurring variants corresponding to different classes of disease severity: Class I G6PD Durham, Class II G6PD Santa Maria, and Class III G6PD A+. The results showed that the G6PD Durham (severe deficiency), and the G6PD Santa Maria and A+ (less severe deficiency) (Class I, II and III, respectively) affect the catalytic efficiency of these enzymes, are more sensitive to temperature denaturing, and affect the stability of the overall protein when compared to the wild type WT-G6PD. In the variants, the exposure of more and buried hydrophobic pockets was induced and monitored with 8-Anilinonaphthalene-1-sulfonic acid (ANS) fluorescence, directly affecting the compaction of structure at different levels and probably reducing the stability of the protein. The degree of functional and structural perturbation by each variant correlates with the clinical severity reported in different patients. PMID:26633385

    Natural selection can act against maladaptive hybridization between co-occurring divergent populations leading to evolution of reproductive isolation among them. A critical unanswered question about this process that provides a basis for the theory of speciation by reinforcement, is whether natural selection can cause hybridization rates to evolve to zero. Here, we investigated this issue in two sibling mosquitoes species, Aedes mariae and Aedes zammitii, that show postmating reproductive isolation (F1 males sterile) and partial premating isolation (different height of mating swarms) that could be reinforced by natural selection against hybridization. In 1986, we created an artificial sympatric area between the two species and sampled about 20,000 individuals over the following 25 years. Between 1986 and 2011, the composition of mating swarms and the hybridization rate between the two species were investigated across time in the sympatric area. Our results showed that A. mariae and A. zammitii have not completed reproductive isolation since their first contact in the artificial sympatric area. We have discussed the relative role of factors such as time of contact, gene flow, strength of natural selection, and biological mechanisms causing prezygotic isolation to explain the observed results.

It contains a rich paleontological record, which comprises many marine invertebrates, several species of bony and cartilaginous fishes, a crocodyliform and turtle remains. Here, we describe a new genus and species of pleurodire turtle from Maria Farinha Formation, based on a nearly complete plastron, an incomplete left pelvic girdle, and four dermal plates of the carapace. We tested the phylogenetic position of Inaechelys pernambucensis gen. et sp. nov. by including it in a comprehensive cladistic analysis of pleurodires. The new species is included within Botrhemydidae, with affinities to Bothremydini, positioned as sister group of Rosasia soutoi. Inaechelys pernambucensis gen. et sp. nov. differs from R. soutoi for the almost straight anterior lobe cranial edge of its plastron, as well as for its pentagonal shaped entoplastron and its abdominal shield midline, which is considerably smaller than the respective femoral shield midline. Inaechelys pernambucensis is the first turtle species formally described from Brazilian Paleocene strata. Within Bothremydidae, it is also the first conclusively fully marine species described for this country. This new record contributes to the understanding of the ecology and paleobiogeographical distribution of Bothremydidae family. PMID:27395602

    Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzymopathy in the world. More than 160 mutations causing the disease have been identified, but only 10% of these variants have been studied at biochemical and biophysical levels. In this study we report on the functional and structural characterization of three naturally occurring variants corresponding to different classes of disease severity: Class I G6PD Durham, Class II G6PD Santa Maria, and Class III G6PD A+. The results showed that the G6PD Durham (severe deficiency), and the G6PD Santa Maria and A+ (less severe deficiency) (Class I, II and III, respectively) affect the catalytic efficiency of these enzymes, are more sensitive to temperature denaturing, and affect the stability of the overall protein when compared to the wild type WT-G6PD. In the variants, the exposure of more and buried hydrophobic pockets was induced and monitored with 8-Anilinonaphthalene-1-sulfonic acid (ANS) fluorescence, directly affecting the compaction of structure at different levels and probably reducing the stability of the protein. The degree of functional and structural perturbation by each variant correlates with the clinical severity reported in different patients.

    Thirty-three sediment samples were collected from the Santa Maria La Reforma coastal lagoon and digested by way of a strong acid mixture and sequential arsenic (As)-extraction method to determine the arsenic (As) content and bioavailability. The As content was determined by atomic fluorescence spectrometry. In addition, grain-size analyses were performed, and organic carbon, carbonate, and iron (Fe) and manganese (Mn) concentrations were determined. Fe and Mn determination was performed by atomic absorption spectroscopy. A Pearson correlation matrix and As enrichment factors were calculated. Sediment concentrations from Santa Maria La Reforma ranged from 3.6 to 25 µg As g(-1) with an average of 13.4 ± 7.6 µg As g(-1). The highest values were observed in the northern (Playa Colorada), north-central (Mocorito River discharge zone), and southern zones ("El Tule" agricultural drain). Most samples were classified as exhibiting no or minor As enrichment and were lower than the threshold effect level (TEL; 7.24 µg g(-1)) for biota (MacDonald et al. in Ecotoxicology 5:253-278, 1996). Low bioavailable As values (<3 %) were measured in the majority of the sediment. The highest As percentages were associated with the oxyhydroxide fraction (F5). The results indicate that As bioavailability is negligible.

    In this study we have applied 3D morphometric analysis of impact craters on the Moon by means of high resolution DTMs derived from LROC (Lunar Reconnaissance Orbiter Camera) NAC (Narrow Angle Camera) (0.5 to 1.5 m/pixel). The objective is twofold: i) evaluating crater degradation and ii) exploring the potential of this approach for Maria stratigraphic interpretation. In relation to the first objective we have considered several craters with different diameters representative of the four classes of degradation being C1 the freshest and C4 the most degraded ones (Arthur et al., 1963; Wilhelms, 1987). DTMs of these craters were elaborated according to a multiscalar approach (Wood, 1996) by testing different ranges of kernel sizes (e.g. 15-35-50-75-100), in order to retrieve morphometric variables such as slope, curvatures and openness. In particular, curvatures were calculated along different planes (e.g. profile curvature and plan curvature) and used to characterize the different sectors of a crater (rim crest, floor, internal slope and related boundaries) enabling us to evaluate its degradation. The gradient of the internal slope of different craters representative of the four classes shows a decrease of the slope mean value from C1 to C4 in relation to crater age and diameter. Indeed degradation is influenced by gravitational processes (landslides, dry flows), as well as space weathering that induces both smoothing effects on the morphologies and infilling processes within the crater, with the main results of lowering and enlarging the rim crest, and shallowing the crater depth. As far as the stratigraphic application is concerned, morphometric analysis was applied to recognize morphologic features within some simple craters, in order to understand the stratigraphic relationships among different lava layers within Mare Serenitatis.

    analysis of data collected and, at the same time, also creates the possibility of access to users not experts in the field of 3D graphics; this has been made possible through the development the project "3DWS" (3D | WEB | SURVEY). The project involved the creation of a container structured as a web site, in which were placed the materials collected and processed including sketches, photographs, vector data, three-dimensional models and analysis issues. Within this system, three-dimensional models developed were then used as a communication tool with immediate visual link to sub-pages with a greater degree of definition. It is a simple and intuitive tree structure that allows both the visitor to the specialist scholar to focus on portions too small and detail of the product, without losing sight of the general configuration of departure. To make feasible a further degree of usability of information, the system has been implemented with image viewers metrics in high definition. The images produced are a fundamental basis, strictly from the point of view of science and technology, for the conservation, management and enhancement of the historical and artistic heritage. The case study investigated is the Chapter House of Santa Maria Novella in Florence.

    The Santa Maria da Vitória River supplies over 30% of the water for the greater Vitória, Espírito Santo, BR metropolitan area, which has a population of roughly 1.6 million people. The availability of clean freshwater is severely limited during periods of heavy rainfall because water sanitation facilities are "clogged" by high sediment discharge. The headwaters of the Santa Maria da Vitória River are characterized by relatively pristine forested environments, transitioning into primarily agricultural and rural land uses, and finally reaching the large urban center of Vitória near its marine receiving waters. The discharge of suspended sediments and dissolved organic matter (DOM) was examined at a 3 hour frequency during heavy storm flows from October 2013 to May 2015 in the Santa Maria da Vitória River main channel and a small tributary, the Mangaraí River. Bulk isotopic analyses were used to determine potential sediment sources and whether specific landscape/land use features were functionalized during periods of high runoff. Likewise, time of flight mass spectrometry (GC-ToF-MS) was used to identify a broad suite of DOM compounds that responded positively with river discharge in an effort to determine the influence of land use on the delivery of dissolved components to the river. For example, the abundance of compounds related to specific agricultural settings increased during storm flow along with anthropogenic DOM sources such as plasticizer and pesticide-derived compounds. Suspended sediment concentrations increased by as much as 70 times during peak river discharge relative to base flow several days earlier with similar increases in particulate organic carbon and nitrogen observed. Results from this study and previous field measurements were integrated into a coupled hydrology-sediment transport model, DHSVM, as part of a dynamic information framework with the goal of predicting water/sediment discharge to inform management and policy sectors of the

    In 1744, the Venetian sea captain Gerolamo Maria Balbi (1693-1761) presented the Senate with a project to build a galea alla ponentina ("galley of Western design") that would join the Venetian fleet based in Corfu. The Senate approved Balbi's project hoping that the galley of new design would restore Venice's maritime reputation after the losses of the war against the Ottomans in 1718. The construction of the galley by the Venetian shipwright Giovan Battista Fausto lasted more than two years and was sent to Corfu in 1746. However, the newly built galley proved to be unseaworthy due to its faulty design and was sent back to Venice where it lay abandoned in the Arsenal until its dismissal in 1753. This article discusses Balbi's galley, which offers a unique glimpse into the technical experimentation in ship design in the Arsenal during the last decades of the Republic of Venice. PMID:26971731

    The ‘Rauisuchia’ are a group of Triassic pseudosuchian archosaurs that displayed a near worldwide distribution. In Brazil, their fossils are found only in the Santa Maria Formation (Paraná Basin) of the Rio Grande do Sul State, specifically in the Middle Triassic Dinodontosaurus assemblage zone (AZ) and the Late Triassic Hyperodapedon AZ (Rauisuchus tiradentes). Between these two cenozones is the Santacruzodon AZ (Middle Triassic), whose record was, until now, restricted to non-mammalian cynodonts and the proterochampsian Chanaresuchus bonapartei. Here we present the first occurrence of a rauisuchian archosaur for this cenozone, from the Schoenstatt outcrop, located near the city of Santa Cruz do Sul and propose a new species, based on biostratigraphical evidence and a comparative osteological analysis.

    With the purpose of determining the principal food resources responsible for maintaining the fishery yield in a section of the São Francisco River, 6 sampling of the fish fauna were made downstream from the Três Marias Dam, from September 1996 to July 1997. A total of 1,127 individuals of 35 species were captured, using gillnets with mesh sizes varying from 3 to 16 cm. The stomach contents of 33 species were examined in order to determine their diets. Five trophic guilds were established, in the following order of importance: ilyophagous, herbivorous, piscivorous, terrestrial invertebrates feeders, and aquatic invertebrates feeders. The resources sustaining the fish fauna were mainly of allochthonous origin. The ichthyonenosis appears to be mainly dependent on the detritus chain. The ciliary forest and seasonal flooding pulses are the main suppliers of food for the fish fauna.

    Occurrence and behaviour of Paromola cuvieri (Crustacea, Decapoda) were recorded by means of the MEMO lander equipped with two digital cameras and deployed in the cold-water coral community of the Santa Maria di Leuca (Mediterranean Sea). A total of 14 individuals were observed at depths between 547 and 648 m; 10 in the coral habitat on coral mounds and 4 off the coral habitat on muddy bottoms. Thirteen specimens recorded were females, one male and all were shown to scavenge the bait. All the specimens carried a sponge on their exoskeleton using the fifth pereiopods. The specimens were distinguishable by the size and shape of the carried sponge. The present observations demonstrate both passive covering behaviour and active behaviour of discouraging approach and attack from competitors or predators, respectively. This study represents the first in situ documentation of Paromola cuvieri behaviour interacting with other deep-sea species in the Mediterranean Sea.

    The relationship between the dispersion and concentration of sediment in the superficial layers of the Tres Marias reservoir and the dynamics of the drainage basins of its tributaries was verified using LANDSAT MSS imagery. The drainage network, dissection patterns, and land use of each watershed were considered in an analysis of multispectral images, corresponding to bands 4,5, and 7, of dry and rainy seasons in 1973, 1975, 1977, and 1978. The superficial layer water layers of the reservoir were also divided according to the grey level pattern of each image. Two field trips were made to collect Secchi depths and in situ water reflectance. It is concluded that it is possible to determine the main factors that act in the dynamics of the drainage basins of a reservoir by simultaneous control of the physical variables and the antropic action of each basin.

    Montemurro is a little centre town located in the Agri Valley (Basilicata Region, Italy) which was affected by two catastrophic events: in the 1842 a very large landslide has damaged great part of the centre and in the 1857 the town was destroyed completely by the "Great Neapolitan Earthquake" (Mallet, 1862), a seismic event having epicenter in the Agri Valley (Cello et al., 2003; Bavusi et al., 2004). Signs of those tragic events can be still found in the fabric of the city. One of these is certainly S. Maria square, a place suspected to house a church before the disastrous events of 1842. This suspicion is supported by a series of evidences: a historical drawing, dating back to before 1842, shows a church in position compatible with the location of the square; in aerial view S. Maria square appears as tear in the fabric of the city; the tales of the erderlies of Montemurro speak about an ancient missing church in the town. Then, in the attempt to resolve the doubt about the presence of the church, a geophysical survey was planned in S. Maria Square with the aim to detect some buried masonry structures related to the church. In this work we selected two active techniques such as the Ground Penetrating Radar (GPR) and the Electrical Resistivity Tomography (ERT). Sixty parallel GPR profiles 0.5 m spaced were gathered in S. Maria Square and in a contiguous street by using a GSSI SIR3000 system with a central frequency antenna of 200 MHz. Processed radargrams showed numerous reflectors and heterogeneities in the subsoil related to manmade objects. Then, a laborious data processing (Nuzzo et al., 2002) allowed to obtain several time-slices showing noticeable reflections compatible with masonry structures. Moreover, two ERT profiles were carried out by using an IRIS Syscal R2 system equipped with a multielectrode cable. The first ERT profile 86 m long and having 44 electrodes 2 m spaced allowed to investigate up to 9 m of depth. The second, overlapped on the previous

    Active neutron spectrometer DAN operates onboard Curiosity rover since its landing in August 2012 and performs measurements of subsurface water distribution along rover's traverse both in passive (monitoring of bulk content of bound water during rover driving) and active (detailed observations of water depth distribution at the selected rover stops) modes. On sol 991 continuing its approach to the main strategic target at Aeolis Mons/Gale crater, Curiosity entered in Marias Pass area where DAN observations both in passive and active mode have discovered highest concentration of bound water (>6.5% in average) ever observed during Curiosity surface operations. At the same time ChemCam instrument identified in this area a bright rock unit (named as Elk target) belonging to Murray formation with abnormally high concentration of SiO2 (>75%) and TiO2 (>3%). Post drive analysis of ChemCam and DAN observations performed in Marias Pass area during 991-997 sols inspired Curiosity Science team to make rover's U-turn and return to the vicinity of Elk target for the detailed investigation of subsurface water distribution and search for rock units similar in elemental composition with Elk target. During this campaign moving with 2-3 m intervals DAN found another several locations with high concentration of subsurface water and ChemCam identified numerous targets with Elk similar composition. These observations have been also supported with contact measurements provided with APXS instrument, which also confirmed high (>70%) silica concentration. Based on the gathered data several hypotheses explaining formation of this area where proposed and possible locations for the next round of drilling and sampling operations where discussed.

    The aim of this study was to evaluate the activity of the EO and its major components of Ocimum basilicum var. Maria Bonita, a genetically improved cultivar, against the fluconazole sensitive and resistant strains of Candida albicans and Cryptococcus neoformans. Geraniol presented better results than the EO, with a low MIC (76 μg/mL against C. neoformans and 152 μg/mL against both Candida strains). The combination of EO, linalool, or geraniol with fluconazole enhanced their antifungal activity, especially against the resistant strain (MIC reduced to 156, 197, and 38 μg/mL, resp.). The ergosterol assay showed that subinhibitory concentrations of the substances were able to reduce the amount of sterol extracted. The substances tested were able to reduce the capsule size which suggests they have an important mechanism of action. Transmission electron microscopy demonstrated cell wall destruction of C. neoformans after treatment with subinhibitory concentrations. In C. albicans ultrastructure alterations such as irregularities in the membrane, presence of vesicles, and cell wall thickening were observed. The biofilm formation was inhibited in both C. albicans strains at MIC and twice MIC. These results provide further support for the use of O. basilicum EO and its major components as a potential source of antifungal agents. PMID:27274752

    The research illustrated in this paper is part of a wider testing ground, aimed at identifying and developing processes of le arning and development taking place in archaeological contexts. These sites are investigated through the use of advanced technology, based on integrated methods of survey of new generation. The aim is to identify alternative languages of representation, able to read and to represent effectively the analyzed object and to propose alternative enjoyment systems. The case study is the Mithraeum in Santa Maria Capua Vetere, for which were carried out surveys with non-contact techniques, based on the use of instrumentations, for the acquisition of colorimetric and metric informations, that exploit a non-invasive approach. Data coming from laser scanner's sensors, combined with GPS receivers, are processed to define a three-dimensional centimetric space, in a single reference system of individual scans. Purpose of this research is to identify representation techniques able to communicate the sense of the multiple interrelations and of interferences among parties, providing the subsequent insertion of data into a wider project of cataloging, fruition and valuation of cultural heritage. The chance to diffuse Digital surveys is now a possible and implementable reality. The purpose is to spread awareness of World Heritage, in a participatory manner and based on the spiri t of knowledge, conveying all the strength of cultural content that heritage has.

    This review celebrates the events of 100 years ago to the month of publication of this December 1998 issue of the British Journal of Radiology, when radium was discovered by the Curies. This followed the earlier discovery in November 1895 of X-rays by Röntgen, which has already been reviewed in the British Journal of Radiology [1] and the discovery in March 1896, by Becquerel, of the phenomenon of radioactivity, which introduces this review. This is particularly relevant as Marie Curie was in 1897 a research student in Becquerel's laboratory. Marie Curie's life in Poland prior to her 1891 departure for Paris is included in this review as are other aspects of her life and work such as her work in World War I with radiological ambulances (known as "Little Curies") on the battlefields of France and Belgium, early experiments with radium and the founding of the Institut du Radium in Paris and of the Radium Institute in Warsaw. Wherever possible I have included appropriate quotations in Marie Curie's own words [2-4] and each section is related in some way to the life and work of Maria or Pierre. This review is completed with details of the re-interment of the bodies of Pierre and Marie on 20 April 1995 in The Panthéon, Paris.

    In "Maria Sklodowska Curie" (MSC) Children's Hospital, Bucharest, Romania, cleft palate repair has been performed according to von Langenbeck since 1984. The speech was good in most patients but wide clefts had a high percentage of fistulas, abnormal speech due to short length and limited mobility of the soft palate. In 2009, the protocol was changed to Gothenburg Delayed Hard Palate Closure, (DHPC) technique. The present evaluation was performed to study the implementation of this technique. One hundred and sixty-eight patients with cleft palate were admitted, 89 isolated cleft palate (ICP), 53 unilateral (UCLP) and 26 bilateral (BCLP). In these, 228 surgical interventions were performed. Soft Palate Repair (SPR) and Hard Palate Repair (HPR) were performed with the DHPC procedure. The transfer to this technique was successfully performed in three steps: one team visit to Gothenburg by a surgeon from MSC and two visits by surgeons from Gothenburg to the MSC. Patients with SPR and HPR were operated on without major complications and there were no differences in results between Gothenburg surgeons and MSC surgeons. The interventions with SPR and HPR technique were proven to be easy to teach and learn and successfully performed without major complications. For cleft patients at MSC hospital it has meant earlier surgery, less re-operations and complications. This report shows a successful change of strategy for palatal repair with improved outcome regarding surgery. In future, speech and growth will be followed on a regular basis and will be compared with results from the Gothenburg Cleft Team.

    Two experimental longline surveys were carried out in the Santa Maria di Leuca (SML) cold-water coral province (Mediterranean Sea) during May-June and September-October 2010 to investigate the effect of corals on fish assemblages. Two types of "megahabitat" characterized by the virtual absence of fishing were explored. One was characterized by complex topography including mesohabitats with carbonate mounds and corals. The other type of megahabitat, although characterized by complex topographic features, lacks carbonate mounds and corals. The fishing vessel was equipped with a 3,000 m monofilament longline with 500 hooks and snoods of 2.5 m in length. A total of 9 hauls, using about 4,500 hooks, were carried out both in the coral megahabitat and in the non-coral megahabitat during each survey. The fish Leucoraja fullonica and Pteroplatytrygon violacea represent new records for the SML coral province. The coral by-catch was only obtained in the coral megahabitat in about 55% of the stations investigated in both surveys. The total catches and the abundance indices of several species were comparable between the two habitat typologies. The species contributing most to the dissimilarity between the two megahabitat fish assemblages were Pagellus bogaraveo, Galeus melastomus, Etmopterus spinax and Helicolenus dactylopterus for density and P. bogaraveo, Conger conger, Polyprion americanus and G. melastomus for biomass. P. bogaraveo was exclusively collected in the coral megahabitat, whereas C. conger, H. dactylopterus and P. americanus were found with greater abundance in the coral than in the non-coral megahabitat. Differences in the sizes between the two megahabitats were detected in E. spinax, G. melastomus, C. conger and H. dactylopterus. Although these differences most probably related to the presence-absence of corals, both megahabitats investigated play the role of attraction-refuge for deep-sea fish fauna, confirming the important role of the whole SML coral

    Background Establishing the distribution of materials in paintings and that of their degradation products by imaging techniques is fundamental to understand the painting technique and can improve our knowledge on the conservation status of the painting. The combined use of chromatographic-mass spectrometric techniques, such as GC/MS or Py/GC/MS, and the chemical mapping of functional groups by imaging SR FTIR in transmission mode on thin sections and SR XRD line scans will be presented as a suitable approach to have a detailed characterisation of the materials in a paint sample, assuring their localisation in the sample build-up. This analytical approach has been used to study samples from Catalan paintings by Josep Maria Sert y Badía (20th century), a muralist achieving international recognition whose canvases adorned international buildings. Results The pigments used by the painter as well as the organic materials used as binders and varnishes could be identified by means of conventional techniques. The distribution of these materials by means of Synchrotron Radiation based techniques allowed to establish the mixtures used by the painter depending on the purpose. Conclusions Results show the suitability of the combined use of SR μFTIR and SR μXRD mapping and conventional techniques to unequivocally identify all the materials present in the sample and their localization in the sample build-up. This kind of approach becomes indispensable to solve the challenge of micro heterogeneous samples. The complementary interpretation of the data obtained with all the different techniques allowed the characterization of both organic and inorganic materials in the samples layer by layer as well as to establish the painting techniques used by Sert in the works-of-art under study.

    The Maria da Fé Shear Zone (MFSZ) is a sinistral strike-slip kilometric-scale structure developed in the late Neoproterozoic during the assembly of Gondwana. The MFSZ development is related to the NW-SE collision between the São Francisco Paleocontinent and the Rio Negro Magmatic Arc, which formed the Ribeira Belt. This paper describes the shear zone in detail, concluding that the orientation and age are consistent with NW-SE shortening during the afore mentioned collision. A U-Pb SHRIMP Concordia age of 586.9 ± 8.7 Ma is reported from zircon grains of a granitic dyke that crystallised synkinematically to the main tectonic activity of the shear zone. Another group of zircon grains from the same sample generated an upper intercept age of 2083 ± 43 Ma anchored in the younger Concordia age. These zircon grains are interpreted as relict grains of the basement from which the granite dyke was generated by partial melting. The temperature during mylonitization in the MFSZ was estimated in the range from 450 to 600 °C, based on microstructures in quartz and feldspar. An earlier collision in the same region, between 640 and 610 Ma, led to an extensive nappe-stack with tectonic transport to ENE, integrating the southern Brasilia Belt. One of the thrust zones between these nappes in the studied area is the Cristina Shear Zone with mylonites that were generated under upper amphibolite to granulite facies conditions. Brittle-ductile E-W metric-scale shear zones are superimposed on the MFSZ, which were active in similar, but probably slightly cooler, metamorphic conditions (≈500 °C).

    The "Santa Maria di Leuca" Cold-Water Coral (CWC) province (northern Ionian Sea) was investigated for the first time to detect eventual occurrence of methane anomalies as a possible indication of hydrocarbon seepage stimulating the coral growth. Most coral mounds have developed in correspondence with tectonic scarps and faults, orthogonal to the southern margin and trending NW-SE, which could be potential sites of gas escape. A visual and instrumental inspection was performed by using a new deep-sea probe equipped with video-cameras, sonar, CTD, methane sensors, and a water sampler. Eight areas were explored by 10 surveys, depths ranging from 380 to 1100 m, for a total of more than 26 h of continuous video and instrumental recording. Sediments were also sampled by gravity corers and analysed in laboratory. The images allowed to assess distribution, abundance and geometry of the colonies, most of which are developed on morphological highs often characterised by tectonic scarps. All data indicate however the lack of a significant occurrence of methane, both in seawater and sediments. No direct or indirect expressions of gas seepage were recognised on the seabed. Weak methane anomalies were detected only in seawater at the base of some fault-linked scarps, where more reducing conditions and bacterial methanogenesis are possibly enhanced by less water circulation. The faults are not fluid-bearing as previously suggested by high-resolution geophysical signatures. The development of the coral colonies thus cannot be attributed to seeping fluids, but to a favourable physiographic position with exposure to nutrient-rich currents.

    Two experimental longline surveys were carried out in the Santa Maria di Leuca (SML) cold-water coral province (Mediterranean Sea) during May–June and September–October 2010 to investigate the effect of corals on fish assemblages. Two types of “megahabitat” characterized by the virtual absence of fishing were explored. One was characterized by complex topography including mesohabitats with carbonate mounds and corals. The other type of megahabitat, although characterized by complex topographic features, lacks carbonate mounds and corals. The fishing vessel was equipped with a 3,000 m monofilament longline with 500 hooks and snoods of 2.5 m in length. A total of 9 hauls, using about 4,500 hooks, were carried out both in the coral megahabitat and in the non-coral megahabitat during each survey. The fish Leucoraja fullonica and Pteroplatytrygon violacea represent new records for the SML coral province. The coral by-catch was only obtained in the coral megahabitat in about 55% of the stations investigated in both surveys. The total catches and the abundance indices of several species were comparable between the two habitat typologies. The species contributing most to the dissimilarity between the two megahabitat fish assemblages were Pagellus bogaraveo, Galeus melastomus, Etmopterus spinax and Helicolenus dactylopterus for density and P. bogaraveo, Conger conger, Polyprion americanus and G. melastomus for biomass. P. bogaraveo was exclusively collected in the coral megahabitat, whereas C. conger, H. dactylopterus and P. americanus were found with greater abundance in the coral than in the non-coral megahabitat. Differences in the sizes between the two megahabitats were detected in E. spinax, G. melastomus, C. conger and H. dactylopterus. Although these differences most probably related to the presence-absence of corals, both megahabitats investigated play the role of attraction-refuge for deep-sea fish fauna, confirming the important role of the whole SML coral

    The land use and types of vegetation in the region of the upper Sao Francisco River, Brazil, are identified. This region comprises the supply basin of the Tres Marias reservoir. Imagery from channels 5 and 7 of the LANDSAT multispectral band scanner during wet and rainy seasons and ground truth data were employed to characterize and map the vegetation, land use, and sedimentary discharges from the reservoir. Agricultural and reforested lands, meadows, and forests are identified. Changes in land use due to human activity are demonstrated.

    During the last decades a number of lacustrine records from Mesoamerica have documented climatic changes and episodes of intense human impact. These records are concentrated in the Maya region and the in high altitude basins of central and eastern Mexico, few studies have been undertaken in western Mexico. We believe that a regional perspective of the recorded changes can provide a better understanding of the climatic trends and mechanisms controlling these changes as well as of the regional extent, intensity and timing of the episodes of human impact. For this reason we started a multidisciplinary project to study the lake sediments from Santa Maria del Oro (SMO), a crater lake in western-central Mexico (750 m asl). SMO is located in a region with tropical sub-humid climate(annual pp 1,250 mm/yr, mean annual temperature 21°C), with a short summer rainy season mainly related with the onset of the North American Monsoon (NAM) and the entrance of Pacific tropical storms and/or hurricanes. This site is therefore site sensitive to variations in the intensity of the NAM circulation. Two master sequences are available from this lake. A ca. 9 m long core (ca. 2,500 yr BP, with 8 AMS 14-C dates) was recovered using a Usinger piston corer from a relatively shallow area of the lake (12 m). These sediments are laminated, mostly with alternation of brown silt and sand layers. It has been studied for: magnetic mineralogy, ostracodes, geochemistry, TIC and TOC. We are now including diatom and pollen data to improve previous paleolimnological interpretations. The second sequence, also ca. 9 m long (ca. 4,500 yr BP, with 6 14-C AMS dates), was recovered using the Limnological Research Center (LRC at the U. of Minnesota) Kullemberg gravity corer (MOLE Mexico-USA-UK collaborative project). This sequence is also laminated, mostly between brown and black silts with finely laminated carbonate layers. High resolution ITRAX XRD elemental analysis data are available for this core. The

    The Medioeval Basilica of Santa Maria of Collemaggio in L'Aquila (XII century) due to the history and the election of Pope Celestino V, the Celestine Pardon, as well as to the artistic features, has a great religious and historic relevance. The whole Basilica was severely damaged during the earthquake of April 2009 and in particular the transetto zone with the cupola collapsed and ruined completely. By means of the project "Starting Afresh with Collemaggio" the Italian company Eni signs a memorandum of understanding with the city of L'Aquila for the restoration of the monument and of Collemaggio site. For this reason a wide and complex multidisciplinary diagnostic campaign was carried out in order to prepare the final design. A specific aspect concerned the diagnosis of the fourteen octagonal pillars of the central nave in terms of state of conservation and structural behavior. Each pillar consists, more or less, in forty big squared blocks of different local carbonatic stones. The diagnosis was preliminary executed by means of visual checks and mapping of the materials and of the structural damages. Subsequently non destructrutive ultrasonic and endoscopic techniques was carried out. The ultrasonic data were elaborated in order to obtain distribution maps of the velocity in the plane sections. To understanding the compressive strength of the stones and the resistance of the pillars, according to structural instances, destructive, compressive tests, and non destructive, ultrasonic and sclerometric measures, were performed of carbonatic blocks quarried in the sourroundings of L'Aquila. The compressive destructive results, inclusive of ultrasonic and sclerometric results, were compared with those non destructive obtained on the stone blocks of the pillars. The results allow to establish that three typologies of carbonatic stone were used. In many cases the surface of the stone, due to previously heartquake, was replaced with thick pieces of different stones

    Santa Maria della Palomba's Sanctuary was built in XV century on a pre-existing medioeval crypt, in a splendid landscape situation, on the front looking south of the ravine on which stands Matera, integrating in a wonderful way underground and sub divo building; in fairly following time one important cycle of frescoes renewed decoration of underground church. In the long run, felt the building into decay, structures and frescoes were flooded and damaged; so that from 1980 were executed important restoration works, realizing ventilation canals under the floor of hypogeic church, in which were incorporated heating pipes, joined to solar thermic panels, wanting to determine the thermo-hygrometric optimum conditions for conservation. Almost thirty years after, willing restorate the frescoes, it was necessary to caracterize completely and objectively physical existing conditions. So was used an integrated mix of some non-invasive sensing techniques: - internal and external high resolution Sanctuary's measurement, using laser scanner 3D, in WebGIS ambient, so as to specify, in particular, whether dimensional data of non accessible parts (thickness of rock-bank, morphology and way of lying down of fracture lines), whether consistence state of frescoes; - thermo-hygrometrical sensing of surfaces, using infrared thermography, during a time of two weeks, in correspondence of many storm, so that to establish the relation between eventual atmospherical conditions variations and changes in conditions of surfaces; - continuous sensing of condition of surfaces, by means of thermo-hygrometrical and temperature sounds; - continuous sensing of operating temperature, by means of a globothermometer; all these tools were linked in a net with a data logger, and informations were transmitted using Web to computer in the office of the Society responsible for the procedure. Remote sensing integrated system proved high liability, allowing many important functions : - to georefer all data

    The present study evaluated for the first time sex steroid profiles and fecundity in females of Prochilodus argenteus from two sections of the São Francisco River Brazil, downstream from the Três Marias Dam, which influences characteristics of their water habitat. The model species in the study, P. argenteus, is an important commercial and recreational species in Brazil. In the region closest to the dam (section 1), females did not reach final oocyte maturation, failed to spawn, and displayed lesser circulating concentrations of testosterone, 17(-hydroxyprogesterone (17(-P) and 17beta-estradiol (E2) than those farther downstream of the dam (section 2). The endocrine and fecundity deficiencies probably are attributed to lower water temperature and oxygen concentration in (section 1). The follicular atresia rate in the region closest to the dam (26%) was greater than those fish captured farther downstream of the dam (13%), after the Abaeté River (section 2). Variations in testosterone, E2 and 17(-P concentrations in section 2, followed gonadal maturation which are typical features of species which have seasonal reproduction, group-synchronous oocyte development, and are single batch spawners such as P. argenteus. Results document the first evidence of endocrine and reproductive dysfunctions caused by inadequate water conditions in a wild population of the migratory species P. argenteus in the São Francisco River, downstream from the Três Marias dam.

    Oil spillage from natural sources is very common in the waters of southern California. Active oil extraction and shipping is occurring concurrently within the region and it is of great interest to resource managers to be able to distinguish between natural seepage and anthropogenic oil spillage. The major goal of this study was to establish the geologic setting, sources, and ultimate dispersal of natural oil seeps in the offshore southern Santa Maria Basin and Santa Barbara Basins. Our surveys focused on likely areas of hydrocarbon seepage that are known to occur between Point Arguello and Ventura, California. Our approach was to 1) document the locations and geochemically fingerprint natural seep oils or tar; 2) geochemically fingerprint coastal tar residues and potential tar sources in this region, both onshore and offshore; 3) establish chemical correlations between offshore active seeps and coastal residues thus linking seep sources to oil residues; 4) measure the rate of natural seepage of individual seeps and attempt to assess regional natural oil and gas seepage rates; and 5) interpret the petroleum system history for the natural seeps. To document the location of sub-sea oil seeps, we first looked into previous studies within and near our survey area. We measured the concentration of methane gas in the water column in areas of reported seepage and found numerous gas plumes and measured high concentrations of methane in the water column. The result of this work showed that the seeps were widely distributed between Point Conception east to the vicinity of Coal Oil Point, and that they by in large occur within the 3-mile limit of California State waters. Subsequent cruises used sidescan and high resolution seismic to map the seafloor, from just south of Point Arguello, east to near Gaviota, California. The results of the methane survey guided the exploration of the area west of Point Conception east to Gaviota using a combination of seismic instruments. The

    Two image processing experiments are described using a MSS-LANDSAT scene from the Tres Marias region and a shuttle Imaging Radar SIR-A image digitized by a vidicon scanner. In the first experiment the study area is analyzed using the original and preprocessed SIR-A image data. The following thematic classes are obtained: (1) water, (2) dense savanna vegetation, (3) sparse savanna vegetation, (4) reforestation areas and (5) bare soil areas. In the second experiment, the SIR-A image was registered together with MSS-LANDSAT bands five, six, and seven. The same five classes mentioned above are obtained. These results are compared with those obtained using solely MSS-LANDSAT data. The spatial information as well as coregistered SIR-A and MSS-LANDSAT data can increase the separability between classes, as compared to the use of raw SIR-A data solely.

    The aragonitic skeletons of bathyal cold-water corals have a high potential as geochemical in situ archives for paleoceanography. Oxygen isotopes and stable carbon isotopes (δ 18O and δ 13C) have been analyzed, as well as trace and minor element compositions (e.g. Mg/Ca, Sr/Ca, U/Ca, B/Ca and P/Ca) in Lophelia pertusa, one of the most important frame-builders at the Santa Maria di Leuca (SML) deep-water coral hotspot in the Central Mediterranean. The Apulian Bank is swept by strong currents of the Adriatic Deep Water Outflow. The temperature of 13.9 °C is the highest temperature recorded for L. pertusa and provides an important end-member of environmental conditions for geochemical analyses on living Atlantic and Mediterranean cold-water corals. Temperature and salinity (38.77 PSU) are stable throughout the year, and thus virtually no changes should be observed in the stable oxygen isotope signal—if the coral precipitates its skeleton in equilibrium with seawater. We measured various marine properties, such as the seawater oxygen isotope composition (δ 18O sw), stable carbon isotope composition (δ 13C DIC) of dissolved inorganic carbon (DIC), and dissolved inorganic nutrient concentrations (PO 4, NO 3, NO 2, NH 3 and SiO 2). Bottom water at the coral sites shows a mean oxygen isotope composition of 1.47‰ δ 18O sw-VSMOW, and δ 13C DIC showed a mean of 1.1‰ VPDB. A section of a living L. pertusa with a thick theca calcification was probed with a Merchantek MicroMill at a high spatial sampling resolution with 10 samples per 1 mm. This reduced the signal-smoothing inherent to conventional sampling. The δ 18O ag of coral aragonite ranges between -2.0‰ and +2.8‰ VPDB and the δ 13C ag ranges between -7.77‰ and +1.47‰ VPDB. The Gaussian data distribution for both parameters, including heavy equilibrium values, suggests the completeness of the captured isotopic variability. The strict linear correlation of δ 13C and δ 18O displays a strong 'kinetic

    This project was undertaken to demonstrate that oil and gas can be drilled and produced safely and economically from a fractured Monterey reservoir in the Santa Maria Basin of California by employing horizontal wellbores and underbalanced drilling technologies. Two vertical wells were previously drilled in this area with heavy mud and conventional completions; neither was commercially productive. A new well was drilled by the project team in 2004 with the objective of accessing an extended length of oil-bearing, high-resistivity Monterey shale via a horizontal wellbore, while implementing managed-pressure drilling (MPD) techniques to avoid formation damage. Initial project meetings were conducted in October 2003. The team confirmed that the demonstration well would be completed open-hole to minimize productivity impairment. Following an overview of the geologic setting and local field experience, critical aspects of the application were identified. At the pre-spud meeting in January 2004, the final well design was confirmed and the well programming/service company requirements assigned. Various design elements were reduced in scope due to significant budgetary constraints. Major alterations to the original plan included: (1) a VSP seismic survey was delayed to a later phase; (2) a new (larger) surface hole would be drilled rather than re-enter an existing well; (3) a 7-in. liner would be placed into the top of the Monterey target as quickly as possible to avoid problems with hole stability; (4) evaluation activities were reduced in scope; (5) geosteering observations for fracture access would be deduced from penetration rate, cuttings description and hydrocarbon in-flow; and (6) rather than use nitrogen, a novel air-injection MPD system was to be implemented.

    Current thinking on the evolution of major lunar morphological features, i.e., large lunar circular basins, and on the nature and origin of surface structures observed in the fill deposits is summarized. The great lunar circular basins must result from high-velocity impact of large bodies with the moon. A hydrostatic mechanism is outlined, and a working hypothesis is presented for the evolution of lunar circular basins subsequent to their origin by impact. In the main appeal is made to Doppler gravity data to support the hypothesis, although photographic and altimetric information is also used. It is considered that all large ringed circular basins follow a common evolutionary path of superisostatic volcanic flooding followed by partial and variable isostatic adjustment. The difference between basins is the amount of flooding, which in turn may be related to the center of figure-center of mass offset of the moon.

    Thank you, Sean, and other colleagues who took the time to nominate me for this extraordinary honor. It is deeply meaningful to be recognized by the AGU, the primary scientific society in which I've participated throughout my career. The ever-expanding reach of AGU provides an outlet for our research much beyond our immediate field, important because, as I tell my students: "It doesn't matter how good your work is if no one knows about it." Viewing the list of distinguished past Hess recipients, many of whom have influenced me greatly, it is impossible to overstate how humbled I am.

  10. Evidence of young volcanic vents in the lunar maria

    NASA Astrophysics Data System (ADS)

    Braden, S.; Robinson, M. S.; Stopar, J. D.

    2013-12-01

    Images from the Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) contain >70 examples of small (10s of m to km), young mare features [1-4] with morphologies similar to the relatively well-studied Ina-D (18.65°N, 5.30°E) [1,5-10]. These features, here called Irregular Mare Patches (IMPs), exhibit sharp, meter-scale morphologies and are distinct from adjacent mare units. Studies of IMPs indicate two common units termed uneven units and smooth units. The uneven unit is present in each IMP and varies in reflectance, surface morphology, and boulder density. The smooth units are mare-like but are often found isolated from the mare, surrounded by the uneven unit. Sharp contacts are found at the boundaries between the uneven and smooth units, or between the uneven unit and the surrounding mare (common in smaller IMPs where there is no distinct occurrence of the smooth unit). Both uneven and smooth units within IMPs have relatively few superposed impact craters with diameters (D) >10 m, consistent with a young age. A combination of crater counts and topographic analyses of four IMPs indicate ages of <100 Ma. We used topography derived from LROC digital terrain models to compare 500x500 m areas from IMPs, impact melt deposits (4 Ma - 100 Ma), and older surfaces (1.6 - 3.6 Ga). Properties measured include the average and maximum slopes, standard deviation of slope (roughness), and relief (maximum - minimum elevation). Most of the IMPs have topographic properties similar to young impact melt deposits such as those from Giordano Bruno, Larmor Q, and Moore F. Constraints on the ages of IMPs are important for bounding the age of the youngest mare eruptions and thus improving our understanding of the lunar heat inventory over time. The morphologies and distinct flow fronts of IMPs may represent the remnants of late-stage volcanic vents. The rate of extrusion and temperature required to produce the sharp flow boundaries found in the IMPs are likely different from broad areas of mare basalt flows. Changes in extrusion rate and temperature commonly occur at vents, which could explain the IMPs' unique morphology. Furthermore, IMPs are often spatially associated with volcanic features such as mare domes (e.g., Cauchy 5), collapse calderas (e.g., Hyginus crater), and large pyroclastic deposits (e.g., Mare Vaporum). Multispectral analysis on a subset of the largest IMPs using combined Clementine UV-VIS data (950/750 nm ratio) and LROC Wide Angle Camera images (320/415 nm ratio) show that the uneven unit is consistent with a mare basalt composition. The multispectral data also suggest the presence of pyroclastic material in the area directly surrounding some of the IMPs, which is consistent with a vent hypothesis. Thus, the morphology, composition, and distribution of IMPs imply that lunar volcanic activity may be much younger than generally recognized. References: [1] Whitaker E. (1972) NASA SP-289.

  12. CERT tribal internship program. Final intern report: Maria Perez, 1994

    SciTech Connect

    1998-09-01

    Historically, American Indian Tribes have lacked sufficient numbers of trained, technical personnel from their communities to serve their communities; tribal expertise in the fields of science, business and engineering being extremely rare and programs to encourage these disciplines almost non-existent. Subsequently, Tribes have made crucial decisions about their land and other facets of Tribal existence based upon outside technical expertise, such as that provided by the United States government and/or private industries. These outside expert opinions rarely took into account the traditional and cultural values of the Tribes being advised. The purpose of this internship was twofold: Create and maintain a working relationship between CERT and Colorado State University (CSU) to plan for the Summit on Tribal human resource development; and Evaluate and engage in current efforts to strengthen the Tribal Resource Institute in Business, Engineering and Science (TRIBES) program. The intern lists the following as the project results: Positive interactions and productive meetings between CERT and CSU; Gathered information from Tribes; CERT database structure modification; Experience as facilitator in participating methods; Preliminary job descriptions for staff of future TRIBES programs; and Additions for the intern`s personal database of professional contacts and resources.

  15. Maria Goeppert Mayer Prize Talk: Superfluid Atom Circuits

    NASA Astrophysics Data System (ADS)

    Campbell, Gretchen

    2016-05-01

    We have performed a series of experiments with ring-shaped Bose-Einstein Condensates, with and without the addition of a ``weak link'' barrier. Weak connections between superconductors or superfluids can differ from classical links due to quantum coherence, which allows for flow without resistance. The properties of a weak link are characterized by a single function, the current-phase relationship. In recent experiments, we have developed a technique to directly measure the current-phase relationship of the weak link. The weak link is created using a laser beam that acts as a barrier across one side of the ring condensate. By rotating the barrier, we can control the current around the ring. When the weak link is rotated at at low rotation rates, we observe phase slips between well-defined, quantized current states, and have demonstrated that the system exhibits hysteresis. At higher rotation rates we have directly measured the onset of resistive flow across the weak link. Such measurements may open new avenues of research in quantum transport. More recently, we have studied the behavior of the ring BEC when the radius is expanded at supersonic rates. Because information can propagate only at the speed of sound, the supersonic expansion creates causally disconnected regions, whose phases evolve at different rates. Such experiments may allow us to study cosmic inflation at laboratory scales.

  17. Galileo imaging observations of Lunar Maria and related deposits

    The Galileo spacecraft imaged parts of the western limb and far side of the Moon in December 1990. Ratios of 0.41/0.56 μm filter images from the Solid State Imaging (SSI) experiment provided information on the titanium content of mare deposits; ratios of the 0.76/0.99 μm images indicated 1 μm absorptions associated with Fe2+ in mafic minerals. Mare ages were derived from crater statistics obtained from Lunar Orbiter images. Results on mare compositions in western Oceanus Procellarum and the Humorum basin are consistent with previous Earth-based observations, thus providing confidence in the use of Galileo data to extract compositional information. Mare units in the Grimaldi and Riccioli basins range in age from 3.25 to 3.48 Ga and consist of medium- to medium-high titanium (<4 to 7% TiO2) content lavas. The Schiller-Zucchius basin shows a higher 0.76/0.99 μm ratio than the surrounding highlands, indicating a potentially higher mafic mineral content consistent with previous interpretations that the area includes mare deposits blanketed by highland ejecta and light plains materials. The oldest mare materials in the Orientale basin occur in south-central Mare Orientale and are 3.7 Ga old; youngest mare materials are in Lacus Autumni and are 2.85 Ga old; these units are medium- to medium-high titanium (<4 to 7% TiO2) basalts. Thus, volcanism was active in Orientale for 0.85 Ga, but lavas were relatively constant in composition. Galileo data suggest that Mendel-Rydberg mare is similar to Mare Orientale; cryptomare are present as well. Thus, the mare lavas on the western limb and far side (to 178°E) are remarkably uniform in composition, being generally of medium- to medium-high titanium content and having relatively low 0.76/0.99 μm ratios. This region of the Moon is between two postulated large impact structures, the Procellarum and the South Pole-Aitken basins, and may have a relatively thick crust. In areas underlain by an inferred thinner crust, i.e., zones within large basins (as at Apollo), titanium content is often higher. However, no mare deposits with titanium abundances approaching those of the high-titanium (9 to 14% TiO2) Apollo 11 and 17 basalts nor of the high-titanium regions of central Oceanus Procellarum are seen on the western limb or eastern far side. Light plains deposits are generally indistinct from the surrounding highlands in the SSI data and are inferred to be derived primarily from the same material that forms the highlands. Some of the light plains are too young to be related to basin-forming impacts, suggesting possible volcanic origin. Dark mantle deposit compositions derived from SSI data are consistent with Earth-based observations of similar near-side deposits and are interpreted to be pyroclastic materials. However, the moderate albedo and 1 μm absorption of the dark mantle deposit on the southwest margin of the Orientale basin suggest it is a local pyroclastic deposit contaminated with underlying highland materials from the Orientale impact.

  20. Maria Goeppert-Mayer Award Talk: Probing the structure and dynamics of biological networks

    NASA Astrophysics Data System (ADS)

    Albert, Reka

    2011-03-01

    The relationship between the structure and dynamics of networks is one of the central topics in network science. In the context of biological regulatory networks at the molecular to cellular level, the dynamics in question is often thought of as information propagation through the network. Quantitative dynamic models help to achieve an understanding of this process, but are difficult to construct and validate because of the scarcity of known mechanistic details and kinetic parameters. Structural and qualitative analysis is emerging as a feasible and useful alternative for interpreting biological signal transduction, and at the same time probing the structure-function relation of these networks. This analysis, however, necessitates the extension of current graph theoretical frameworks to incorporate features such as the positive or negative nature of interactions and synergistic behaviors among multiple components. This talk will present a method for structural analysis in an augmented graph framework that can probe the dynamics of information transfer. The first step is to expand the network to a richer representation that incorporates negative and synergistic regulation by the addition of pseudo-nodes and new edges. Our method simulates both knockout and constitutive activation of components as node disruptions, and takes into account the possible cascading effects of a node's disruption. We introduce the concept of elementary signaling mode (ESM), as the minimal set of nodes that can perform signal transduction independently. As a first application of this method we ranked the importance of signaling components by the effects of their perturbation on the ESMs of the network. Validation on various regulatory networks shows that this method can effectively uncover the essentiality of components mediating a signal transduction process and agrees with dynamic simulation results and experimental observations. Future applications include determining the ESMs that (do not) support steady states.

    1996-03-01

    During the heteroepitaxy of strongly dissimilar materials, the complex growth kinetics and interface reactions of the first few atomic or molecular layers can control the structure and morphology of the next several hundred layers. Within these first few layers, the atomic and electronic structure continuously evolves as the bare substrate reacts to form a new interface compound, which in turn serves as the substrate for the nucleation and coalescence of subsequent layers. The substrate, reacted interface layer and subsequent layers each have distinct activation barriers for diffusion, and may have different step and island distributions. This results in variation of the time scales for diffusion to a step edge and interlayer transport (crossing atomic steps) relative to that for deposition of a monolayer, both during deposition and in different places on the growing surface. Using the powerful in-situ combination of X-ray photoelectron spectroscopy and diffraction, we have monitored this evolution of the atomic and electronic structure when the insulator calcium fluoride is deposited on silicon. We observe and explain different photoemission and auger emission energies for the first eight atomic layers (Ca-F-F-Ca-F-F-Ca-F), and exploit energy- resolved diffraction to separately determine their local structure. Using transmission electron microscopy, we relate the patterns of strain relaxation in thicker films to the initial nucleation behavior deduced from photoemission measurements. We find that terrace or step nucleation leads to laminar films, although with different relaxation patterns; combined step and terrace nucleation leads to rough films due to different upper- layer nucleation rates on the differently sized step- and terrace- nucleated islands. The results are explained within a general phenomenological model we have developed for the heteroepitaxy of dissimilar materials. This work was performed in collaboration with U. Hessinger, M. Leskovar, E. Rotenberg and J. D. Denlinger, and supported by the U. S. Department of Energy

  11. Bioclastic turbiditic reservoirs: San Giorgio, Santa Maria Mare, Sarago Mare fields (Italy)

    SciTech Connect

    Heritier, F.E.; Soudet, H.; Richert, J.

    1987-05-01

    These three fields and the associated Mormora discovery are located along the coastline of the central Adriatic Sea or on the very proximate shelf south of Ancona. Geologically they belong to the Marches basin. These fields are situated on highly faulted northwest-trending anticlines which are related to a north-south shear zone under the disharmonic cover of late Miocene and early Pliocene shales. Oil and gas are contained in the Scaglia limestone formation of Late Cretaceous to Paleocene age whose reservoirs consist of high-energy bioclastic grainstones interbedded in open marine chalk deposits, and spread and deposited by turbiditic currents. The diagenesis of these bioclastic grainstones is closely related to the thickness and composition of the different beds and is chiefly located at the top and bottom of them. It is also related to the fluid content of the reservoir. Fracturing of these beds under the tectonic stresses is linked to the reservoir's characteristics and to the extension of consolidated facies by diagenesis. This fracturing is responsible for the production behavior of the different wells. Source rocks are the evaporitic shales of upper Miocene age, mature in the deeper part of the Marches basin under the upper Pliocene olistostromes.

    Evora Cathedral (one of the most emblematic monuments of Evora - Portugal) has suffered several conservation and restoration interventions through the ages, without, however, any type of previous knowledge about mortars and materials used. This work was carried out in order to identify the mortar's composition in different locations, which were attributed to different construction or conservation periods. The characterisation methodology involved a multidisciplinary set of chemical, physical, microstructural and mechanical techniques, and gave special attention to the use of microstructural characterisation techniques, particularly petrographical analysis and scanning electron microscopy for the identification of the mortar's constituents as well as in the evaluation of the state of conservation. The test results showed that two types of aerial binders were used, dolomitic and calcitic limes, the former being predominant. The aggregates used have a siliceous nature and are similar in composition to the granodiorites of the region around Evora. The mortars differ in the aggregate contents and, in some cases, crushed bricks were used as an additive.

  13. Depositional environments of the Santa Margarita Formation in the Miocene Santa Maria basin, Huasna syncline

    SciTech Connect

    Phillips, R.L. )

    1991-02-01

    Preliminary investigation of the depositional environments of the middle sandstone member of the late middle Miocene Santa Margarita Formation in the Huasna syncline suggests a current-dominated shallow shelf environment. Progradation of coarse-grained clastic and bioclastic-rich sediment over siltstone documents the initial stage of deposition of this sand body. Overlying the basal intensely bioturbated bioclastic sediments are large-scale tabular cross-beds, up to 16 m thick, interbedded with tabular lag deposits of barnacles, oysters, and echinoids. The tabular fossil-rich beds, which form sequences up to 6 m thick between the large-scale cross-beds, represent either deposition of bottom set beds of the large-scale cross-beds or current swept lag deposits. Increasing energy conditions are recorded vertically by a decrease in the amount of bioturbation and by an increase in large-scale cross-bed sets and cosets. however, in the northern outcrop area subtidal channels are incised into the upper bioclastic sediments suggesting local shoaling conditions. Paleocurrent data record a unidirectional southwest-directed current trend normal to the basin axis and the East Huasna fault. The coarse clastic deposition terminates with deposition of siltstone as energy conditions decreased and water depth again increased. A current-swept shallow shelf containing extensive sandwaves comprises the major depositional environments. The paleocurrent data and large-scale cross-beds suggest that the shallow shelf extended to the east of the Huasna syncline and that the currents were most likely tidal in origin.

    1993-01-01

    The second flyby of the Earth-Moon System by Galileo occurred on December 7, 1992, on its trajectory toward Jupiter. The flyby took the spacecraft over the lunar north polar region from the dark farside and continued across the illuminated nearside. This provided the first opportunity to observe northern and northeastern limb regions with a modern, multispectral imaging system with high spatial resolution (up to 1.1 km/pixel). Scientific objectives included compositional assessment of previously uncharacterized mare regions, study of various light plains materials, and assessment of dark mantle deposits (DMD) and dark halo craters (DHC). Color composite images were prepared from ratios of Galileo SSI filter data (0.76/0.41 yields red; 0.76/0.99 yields green; 0.41/0.76 yields blue) and used for preliminary comparison of units. The 0.41/0.76 ratio has been empirically correlated to Ti content of mare soils (blue is relatively high, red is relatively low). The relative strengths of the ferrous one micron absorption in mafic minerals can be compared using the 0.76/0.99 ratio. In addition, relative ages of units analyzed spectrally were determined from crater statistics using Lunar Orbiter images following the techniques of Neukum et al. Mare deposits analyzed include Mare Humboldtianum, central and eastern Mare Frigoris, Mare Crisium and other deposits in the Crisium Basin, and isolated mare patches on the northeastern lunar limb. Preliminary results show a diversity of 0.41/0.76 micron signatures, implying a wide range of titanium contents. Some light plains units are similar to units found at the Apollo 16 site; others may be ancient mare materials. Dark mantle deposits (DMD) analyzed also are available.

  16. Conceptual design of equipment to excavate and transport regolith from the lunar maria

    NASA Technical Reports Server (NTRS)

    Detwiler, Mark; Foong, Chee Seng; Stocklin, Catherine

    1990-01-01

    NASA hopes to have a manned lunar outpost completed by 2005. In order to establish the base, regolith must be excavated from the lunar surface. Regolith will be used as a source for life-supporting elements and as radiation shielding for the lunar outpost. The design team from the University of Texas at Austin designed excavation and transportation equipment for initial operations of the lunar base. The design team also characterized the elements to be found in the regolith and determined the power required to excavate regolith. The characterization of the soil was based on a literature review of lunar geography. Power requirements for excavation were developed by adapting terrestrial equations for excavation power requirements and adapting them to lunar soil conditions. The design of the excavation and transportation equipment was broken into three functions: loosing, collecting, and transporting. A scarifier was selected to loosen, a bucket was selected to collect, and a load-haul system was selected to transport. The functions are powered by a modular fuel cell powered vehicle that provides power for motion of the equipment.

    1996-01-01

    A benign syndrome of acute ophthalmoplegia, ataxia, and areflexia is commonly known as the Miller Fisher syndrome. It is generally believed that Miller Fisher syndrome is a type of Guillain-Barré syndrome, but several authors believe it to be a separate clinical entity caused by a central nervous system lesion. Eight patients with Miller Fisher syndrome diagnosis, admitted to our department in the last 20 years, were reviewed. Neurophysiological studies were carefully reviewed. Our patients had a clinical presentation and evolution identical to that described previously. Neurophysiological abnormalities were found in all patients and were characteristic of a sensory axonal neuropathy, with damage of the facial nerves and occasional demyelination of peripheral nerves. The pattern of abnormalities is distinct from the usual features seen in Guillain-Barré syndrome. The CT scan, MRI, and Evoked Potentials investigations in our patients did not confirm central nervous system lesion. Nevertheless we did not exclude the possibility of coexisting damage to the central nervous system in some patients, as shown in Chronic Inflammatory Demyelinating Polyneuropathy.

    2005-03-01

    In epitaxial complex oxide systems, epitaxial strain, cation substitution and nanofabrication are just some ways in which their magnetic, electronic and optical properties may be tuned. In addition, their surfaces and interfaces provide a rich playground for the exploration of novel magnetic properties not found in the bulk constituents and the development of functional interfaces to be incorporated into technological applications. We have probed magnetism in complex oxide materials through studies of epitaxial oxide thin films, nanostructures and junction devices. With our ability to control oxide film growth as well as our expertise in nanofabrication, we have been able to study the effects of surfaces and interfaces on magnetism in ultra-thin magnetic oxide films and magnetic oxide nanostructures. For example, we have found that the nature of local magnetic structure in submicron islands of colossal magnetoresistance (CMR) material reveals the importance of shape anisotropy as well as magnetostriction in determining the micromagnetics in such small CMR structures. We have also studied epitaxial oxide trilayer junctions composed of magnetite (Fe3O4) and doped manganite (La0.7Sr0.3MnO3) in which we have confirmed the theoretically predicted negative spin polarization of Fe3O4. Transport through the barrier can be understood in terms of hopping transport through localized states that preserves electron spin information.

  7. Field classification and oxygen isotope composition of quartz cherts from the Monterey Formation, Santa Maria basin, California

    1991-02-01

    Field, petrographic, and isotopic studies indicate that chertification occurred at different times during the burial history of the Miocene Monterey Formation sediments. Early, intermediate, late, and dolomite-replacement quartz cherts can be identified by differential compaction, cross-cutting relationships, and by precursor lithology. The authors' oxygen isotope analyses largely substantiate their field and petrographic classification of Monterey cherts. Early quartz cherts contain oxygen isotope ratios of {delta}{sup 18}O (SMOW) = 24.5 to 29.4{per thousand}, intermediate cherts = 26.5 to 29.4{per thousand}, late cherts = 24.8 to 25.9{per thousand}, dolomite-replacement cherts = 27.9 to 30.2{per thousand}, and shale-associated cherts = 29.4 to 31.2{per thousand}. Assuming a prograde sequence of chertification, and that {delta}{sup 18}O{sub pore water} remained relatively constant at about 0{per thousand} (SMOW), shale-associated cherts were formed the earliest at 40 to 49C, dolomite-replacement cherts followed at 45 to 56C, normal cherts formed between 48 and 64C, and late cherts formed at 67 to 73C (temperature expression of Matsuhisa et al., 1979). Early quartz cherts apparently inherited their differential compaction features from early-formed opal-CT cherts; their isotopic composition indicates replacement by quartz at a wide range of temperatures, from 48 to 75C. Further synthesis of field and isotopic data will also help constrain the oxygen isotopic evolution of the Monterey Formation pore waters.

  9. Emotions induced by operatic music: psychophysiological effects of music, plot, and acting: a scientist's tribute to Maria Callas.

    2011-06-01

    Operatic music involves both singing and acting (as well as rich audiovisual background arising from the orchestra and elaborate scenery and costumes) that multiply the mechanisms by which emotions are induced in listeners. The present study investigated the effects of music, plot, and acting performance on emotions induced by opera. There were three experimental conditions: (1) participants listened to a musically complex and dramatically coherent excerpt from Tosca; (2) they read a summary of the plot and listened to the same musical excerpt again; and (3) they re-listened to music while they watched the subtitled film of this acting performance. In addition, a control condition was included, in which an independent sample of participants succesively listened three times to the same musical excerpt. We measured subjective changes using both dimensional, and specific music-induced emotion questionnaires. Cardiovascular, electrodermal, and respiratory responses were also recorded, and the participants kept track of their musical chills. Music listening alone elicited positive emotion and autonomic arousal, seen in faster heart rate, but slower respiration rate and reduced skin conductance. Knowing the (sad) plot while listening to the music a second time reduced positive emotions (peacefulness, joyful activation), and increased negative ones (sadness), while high autonomic arousal was maintained. Watching the acting performance increased emotional arousal and changed its valence again (from less positive/sad to transcendent), in the context of continued high autonomic arousal. The repeated exposure to music did not by itself induce this pattern of modifications. These results indicate that the multiple musical and dramatic means involved in operatic performance specifically contribute to the genesis of music-induced emotions and their physiological correlates.

  10. The Statherian itabirite-bearing sequence from the Morro Escuro Ridge, Santa Maria de Itabira, Minas Gerais, Brazil

    The itabirite-bearing metasedimentary sequence from Morro Escuro Ridge comprises the basal units of the Espinhaço Supergroup and makes up a small tectonic inlier developed during one of the Brasiliano orogenic events (800-500 Ma), amongst horses of the Archean TTG gneisses, including sheared granites of the anorogenic Borrachudos Suite (˜1700 Ma). The metasedimentary rocks are comprised of low-to intermediate-amphibolite facies schists, quartzites, conglomerates and banded iron formation (itabirite) correlatable with the sequences of the Serro Group, which underlies the metasedimentary rocks of the Espinhaço Supergroup in the Serra da Serpentina Ridge. A maximum Statherian deposition age (1668 Ma) was established using SHRIMP U-Pb isotopic constraints on zircon grains from conglomerate and quartzite units overlying the itabirite. The itabirite is predominantly hematitic and its geochemical characteristics are typical of a Lake Superior-type BIF deposited in a platformal, suboxic to anoxic environment distant from Fe-bearing hydrothermal vents. Close to the contact zone with amphibolites of the Early Neoproterozoic Pedro Lessa mafic suite, an increase of the magnetite content and crystallization of metasomatic Mg-hornblende and Ce-allanite can be observed. These mineralogical changes developed preferentially along the igneous contact zone but are probably co-genetic with the formation of alteration haloes in zircon grains during the Neoproterozoic Brasiliano orogeny (506 ± 6 Ma).

    A unique sensing platform, comprising an electromagnetic field detector and an acoustic resonator, has been used as a wireless system for remote sensing of biorecognition events. The MARS (Magnetic Acoustic Resonator Sensor) technique has proven useful for detecting the formation of protein multilayers derived from specific binding phenomena. The technique enables multifrequency analysis, without the need of electrodes attached to the sensing element, and also facilitates the in situ surface modification of the substrate for antibody attachment. The MARS sensor was utilized as the platform on which a standard immunoassay was carried out. Two different conditions for the attachment of the first antibody to the quartz surface were tested: (i) Adsorption of the antibody onto the surface of a bare quartz disc; (ii) covalent immobilization of the antibody to a chemically modified quartz surface. Both methods can be successfully utilized for the 'label-less' detection of the biorecognition event between goat IgG and anti-goat IgG by analysis of the multifrequency spectrum. Covalent attachment of the primary antibody results in a more efficient immobilization, with higher surface density, and a consistently enhanced response for the binding of the secondary antibody. This approach will be of interest to life scientists and biochemists that require high performance assay methodologies that do not use chemical labels.

  12. Late Holocene Multiproxy Record (Palynology, Stable Isotope and Multi-Element Geochemistry) of Lake Santa Maria del Oro, Western Mesoamerica.

    We present the palynological, stable isotope and major element (ITRAX X-Ray fluorescence) data from a 850-cm sediment sequence from the deepest part of lake Santa María del Oro (SMO) in order to document changes in the climatic and limnological conditions and in the vegetation for the last ca. 5000 yr. SMO is a crater lake of (750 m asl, 2 km diam.) located in a tropical sub-humid climate (1250 mm/yr, average annual temperature 21° C) at the transition between the temperate central Mexican highlands and the arid northern regions. Tropical deciduous forests which loose their leaves for 8 months in a year and the tropical oak forests are the main plant communities in the lake catchments. The western part of Mesoamerica is the cradle of maize (Zea mays ssp. mays ) agriculture; this region is probably one of the two centers of maize domestication based on the presence of one of its closets wild relative teosinte (Zea mays ssp. parviglumis ). Chronology was established with 8 AMS radiocarbon dates. Sediments are finely laminated, with some intervals dominated by black and brown clayey silt and others by brown clayey silt and calcareous silt. In some levels, laminae are characterized by silts and fine sands. Authigenic carbonate laminations are formed during the summer season, when the highest temperatures are reached in the area. Throughout the pollen analysis, teosinte pollen and maize pollen was recorded. The major element concentration (Ca and Ti) in the bulk sediments was analyzed by ITRAX multi-element scanner and the isotopic data (δ13C and δ18O) in authigenic carbonates by mass spectrometer. Ca and Ti ITRAX intensities were calibrated to mass % by using the linear relationship between ITRAX intensity and mass % obtained through conventional XRF analysis. Preliminary pollen data of SMO sediments indicates abundant pollen of teosinte from ca. 2000 to 100 BC and maize presence at ca. 1300 BC and ca. 900 BC along with high charcoal particle concentrations, suggesting early agricultural activity in the area, being the first record of maize in the western region of Mesoamerica. The phases with higher concentration of Ti are identified as periods of higher inflow into the lake basin (BC 1700-1400, 0- AD 200, AD 900 and AD 1800-1900). Phases of higher evaporative conditions are identify at ca. BC 700, BC 400, AD 400-800 and AD 1900-2003 based on Ca high values and enriched δ18O and δ13C. There exists a negative relationship between Ca and Ti. Evidence of changes in climatic conditions is inferred from the data.

    The noxious potential of metallurgical tailings from the Ag/Pb/Zn/Cu mining district of Sta. María de la Paz (Mexico) is ascertained via the chemical characterization of slag material. Batch experiments using various extraction solutions (e.g. natural rainwater, water rich in humic substances, ammonium nitrate solution) revealed information on the dissolution behaviour of the elements Fe, Mn, Ni, Cu, Zn, As, Ba and Pb from slag with respect of grain size (slag material screened under 2 mm and analytically fine fraction) and elution time (2, 7.5, 24 and 240 h). An initial ecotoxicological assessment of the results is made and the environmental danger caused by large volumes of slag tailings is discussed.

    1993-01-01

    New visible and near-infrared multispectral data of the Moon were obtained by the Galileo spacecraft in December, 1990. These data were calibrated with Earth-based spectral observations of the nearside to compare compositional information to previously uncharacterized mare basalts filling craters and basins on the western near side and eastern far side. A Galileo-based spectral classification scheme, modified from the Earth-based scheme developed by Pieters, designates the different spectral classifications of mare basalt observed using the 0.41/0.56 micron reflectance ratio (titanium content), 0.56 micron reflectance values (albedo), and 0.76/0.99 micron reflectance ratio (absorption due to Fe(2+) in mafic minerals and glass). In addition, age determinations from crater counts and results of a linear spectral mixing model were used to assess the volcanic histories of specific regions of interest. These interpreted histories were related to models of mare basalt petrogenesis in an attempt to better understand the evolution of lunar volcanism.

    The evolution, geology, geochemistry and topology of the Flamsteed region of Oceanus Procellarum are examined, considering remote sensing data including multispectral images and spectral reflectance measurements along with crater degradation studies and radar backscatter. Seven spectrally distinct basaltic units ranging in age from 2.5 plus or minus 0.5 to 3.5 plus or minus 0.5 billion years have been identified. The earliest units of the mapped area are composed of highlands material and include partially flooded impact craters, and the oldest surface exposed mare basalts are very low Ti basalts of the Telemann formation.

    1997-04-01

    Ultrashort x-ray pulses give researchers a new window through which to view the natural world, with the ability to spatially and temporally resolve processes basic to material and chemical systems. In the 1990's, there has been a revolution in the technology of laser sources, resulting in the ability to simply and reliably produce light pulses as short as 3 optical cycles in duration, both in the visible and the x-ray region of the spectrum. Also, powerful new techniques to obtain accurate pictures of the exact shape of these ultrashort light pulses have been developed, which are revolutionizing the way we think about and use light. Finally, using harmonic techniques to up-convert visible light into the x-ray region, we can generate coherent and tunable light below 5 nm, with unprecedented short duration (3-10 fs).

    2000-03-01

    Computer simulations of soft materials and complex fluids have provided a wealth of information on these systems that elucidates and guides experimental investigation. Molecular dynamics (MD) computer simulation in particular provides a unique window into the complex microscopic processes that control, e.g., the transformation of a liquid to a glass. As the glass transition is approached, particles (atoms or molecules in the case of simple liquids, monomers in the case of polymer melts, or colloids in the case of colloidal suspensions) become temporarily localized and relaxation times increase by many orders of magnitude. At the same time, MD simulations have shown that the dynamics becomes increasingly correlated and spatially heterogeneous, developing a characteristic dynamical length scale which grows rapidly as the glass transition is approached, despite the fact that static density and composition correlations remain short-ranged. In this talk, we review our investigations of dynamical heterogeneity and correlated particle motion in several model glass-forming liquids and polymer melts using MD simulation. We compare our results with new experimental data on glass-forming colloidal suspensions, and address the possible implications of our findings for nano-confined fluids, filled polymers and nanocomposites.

    The construction of the Cistercian Monastery began at 1180, in an initial Late Romanesque style in which the Church was erected; later on, in 1258, the church underwent a severe fire, only the apse stood standing. The church was reconstructed at the end of the 13th century in Mudejar style. Gothic style was used later on, in the 16th century, for the reconstruction of the funerary chapel, and Renaissance style for the Plateresque door in between the church and the sacristy. At the end of the 16th century, the main door to access the church was built in Baroque style. In 1836, the Ecclesiastical Confiscations resulted on transfer the Monastery into particular owners. This fact favoured its abandon and ruin state until 1979, when architect Mariano Garcia Benito purchased the property and started the conservation and consolidation of the complex, beginning with the Bell Tower. Natural stone materials used in the Monastery are igneous (granite) and metamorphic rocks (gneiss and schist), and artificial stone materials are bricks and mortars, both joint and rendering ones. Granite is the most abundant material used in the complex, with a structural/reinforcing role in elements such as lintels, jambs, buttresses, or bottom areas of the walls with greater sizes and better dimensioned. Some pillars are granite built, from the large ashlars of the sacristy, to the rubble-work of the Mozarab chapel. Two types of monzogranite can be differentiated in relation to distinct constructive stages: the coarse texture monzogranite is used in the first building stages, while the fine texture monzogranite was employed mainly from 17th century on. Petrophysical characteristics of these granites are different but show a good quality to be used in construction. Nevertheless, the abandon and partial ruin of the complex, the devastating fire events (the second one in 1743) leaded to the decay acceleration of the monumental complex, being nowadays the church in ruin, with no roofs and walls in the risk of collapse, leaving the wall fillings exposed to the environment, speeding up the deterioration of the monumental complex. The Monastery construction was supplied of the natural stone closest to it, the monzogranite that outcrops in the surroundings of the monastic complex, with main differences based on its grain-size. The Monastery settles in a coarse grain-size monzogranite area, material that was used in its first building stages. Provenance quarries are scarce hundreds meters far from the building, and a little bit further, in the San Esteban hill, we can find the fine grain size area. In both areas, marks of the extractive processes can be found. The geological provenance of the Monastery building materials has been for first time located with the importance it may have for restoration purposes.

    A study was undertaken to investigate the impacts to deep-water, hard-bottom benthic communities associated with disturbances caused by oil and gas exploratory operations on the Outer Continental Shelf of California. A literature survey compiled a history of exploratory oil and gas development and located wellsites where disturbances due to anchoring or discharges probably impacted hard-bottom communities. A photographic survey of the selected sites collected data for subsequent analyses on the type, distribution, and longevity of anchoring disturbances. Analyses of the field data revealed that less than one percent of hard-bottom habitat within the area of the mooring system was disturbed. The results of the study indicated that hard-bottom epifaunal communities do recover from these disturbances; however, recovery is highly dependent on the type of disturbance.

    The mudéjar church of Santa María (Ateca) is valuable for its architecture and the altarpiece contained inside. Ateca is a village with continental climate characterized by cold winters and hot summers. In this paper we are interested in analysing the effect of temperature and relative humidity (RH) changes produced by the heating system on the altarpiece. Therefore, a monitoring system of 15 temperature and 15 relative humidity sensors was installed with a recording frequency of a data point per minute. The main contribution of this paper is the quantitative study of the effect of the heating system on the thermo-hygrometric parameters using statistical techniques such as ANOVA, mean daily trajectories or bivariate plots, and the proposal of an innovative dynamic contour plot. As results, the heating system produces a substantial increase (decrease) of temperature (RH) causing an hourly variation of these physical parameters detrimental to the conservation of the altarpiece, especially in its higher areas.

    Various mineral processing operations to produce pure metals from mineral ores generate sludges, residues, and other unwanted by-products/wastes. As a general practice, these wastes are either stored in a reservoir or disposed in the surrounding of mining/smelting areas, which might cause adverse environmental impacts. Therefore, it is important to understand the various characteristics like heavy metal leaching features and potential toxicity of these metallurgical wastes. In this study, zinc plant leach residues (ZLRs) were collected from a currently operating Zn metallurgical industry located in Minas Gerais (Brazil) and investigated for their potential toxicity, fractionation, and leachability. Three different ZLR samples (ZLR1, ZLR2, and ZLR3) were collected, based on their age of production and deposition. They mainly consisted of Fe (6-11.5 %), Zn (2.5 to 5.0 %), and Pb (1.5 to 2.5 %) and minor concentrations of Al, Cd, Cu, and Mn, depending on the sample age. Toxicity Characteristic Leaching Procedure (TCLP) results revealed that these wastes are hazardous for the environment. Accelerated Community Bureau of Reference (BCR) sequential extraction clearly showed that potentially toxic heavy metals such as Cd, Cu, Pb, and Zn can be released into the environment in high quantities under mild acidic conditions. The results of the liquid-solid partitioning as a function of pH showed that pH plays an important role in the leachability of metals from these residues. At low pH (pH 2.5), high concentrations of metals can be leached: 67, 25, and 7 % of Zn can be leached from leach residues ZLR1, ZLR2, and ZLR3, respectively. The release of metals decreased with increasing pH. Geochemical modeling of the pH-dependent leaching was also performed to determine which geochemical process controls the leachability/solubility of the heavy metals. This study showed that the studied ZLRs contain significant concentrations of non-residual extractable fractions of Zn and can be seen as a potential secondary resource for Zn. PMID:26728285

    This review aims to commemorate the life, and the accomplishments of Pierre and Marie Curie in Physics and in Medicine. Although they are primarily known for their discoveries of the elements of radium and polonium, which took place two years after the discovery of radioactivity by Henry Becquerel, Pierre's discovery of the piezo-electric phenomenon, his research on crystal symmetry, magnetism and paramagnetic substances, are equally important. With the discovery of the two radioactive elements, Pierre and Marie Curie established the new field of Nuclear Physics. It is not an over-statement to say that their discovery contributed much to our modern way of life. Marie received the Nobel Prize twice and later she became the first woman to become member of the French Academy of Sciences. Today, both Pierre and Marie Curie rest in Panthéon, in Paris.

    An analysis was carried out of the microbiological investigations of clinical material samples obtained from the patients of two oncology centres belonging to the Warsaw Oncology Centre. Microorganisms cultured from urine, blood, catheters, smears of wounds and other materials were analysed. From 4839 clinical material samples from the Ursynów centre 1755 bacterial strains were isolated. From 423 samples from the centre in Wawelska Street 171 strains were obtained. In infections of patients from the centres the number of Gram-positive cocci was twice that of Gram-negative rods. In the investigated clinical material S. aureus was the most frequently isolated Gram-positive coccus, while E. coli was the most frequent species among Gram-negative bacteria. In the infections of oncological patients a considerable frequency was noted of yeast-like fungi, especially C. albicans. Particularly disquieting was the increasing number of isolates of C. glabrata and C. krusei strains resistant to fluconazole.

  12. BOOK REVIEW: Galileo's Muse: Renaissance Mathematics and the Arts

    NASA Astrophysics Data System (ADS)

    Peterson, Mark; Sterken, Christiaan

    2013-12-01

    Galileo's Muse is a book that focuses on the life and thought of Galileo Galilei. The Prologue consists of a first chapter on Galileo the humanist and deals with Galileo's influence on his student Vincenzo Viviani (who wrote a biography of Galileo). This introductory chapter is followed by a very nice chapter that describes the classical legacy: Pythagoreanism and Platonism, Euclid and Archimedes, and Plutarch and Ptolemy. The author explicates the distinction between Greek and Roman contributions to the classical legacy, an explanation that is crucial for understanding Galileo and Renaissance mathematics. The following eleven chapters of this book arranged in a kind of quadrivium, viz., Poetry, Painting, Music, Architecture present arguments to support the author's thesis that the driver for Galileo's genius was not Renaissance science as is generally accepted but Renaissance arts brought forth by poets, painters, musicians, and architects. These four sets of chapters describe the underlying mathematics in poetry, visual arts, music and architecture. Likewise, Peterson stresses the impact of the philosophical overtones present in geometry, but absent in algebra and its equations. Basically, the author writes about Galileo, while trying to ignore the Copernican controversy, which he sees as distracting attention from Galileo's scientific legacy. As such, his story deviates from the standard myth on Galileo. But the book also looks at other eminent characters, such as Galileo's father Vincenzo (who cultivated music and music theory), the painter Piero della Francesca (who featured elaborate perspectives in his work), Dante Alighieri (author of the Divina Commedia), Filippo Brunelleschi (who engineered the dome of the Basilica di Santa Maria del Fiore in Florence, Johannes Kepler (a strong supporter of Galileo's Copernicanism), etc. This book is very well documented: it offers, for each chapter, a wide selection of excellent biographical notes, and includes a fine

    Dante's Divine Comedy is universally acclaimed as one of the great masterpieces in world literature. It is written in first person singular and this gives an intimate acquaintance with the vision of the poet. In the Fifth Canto, he exquisitely describes the story of Paolo Malatesta and Francesca da Rimini, illicit lovers killed by Francesca's husband, Gianciotto Malatesta. The story, dramatically told by Francesca, deeply moves the poet, who suddenly faints. In the words of Dante himself: 'E caddi come corpo morto cade' (And fell, even as a dead body falls). This probably is the first literary description of an emotional syncope in world literature. We found that three great plastic artists (John Flaxman, William Blake and Gustave Doré) captured the crucial moment of the syncope in three extraordinary images left for posterity. PMID:24914636

    In their paper Gross et al., 2011 present an excellent description of a series of outcrops from the Eirunepe region in western Amazonia (Brazil). The authors interpret these sediments as relics of a Late Miocene anastomosing fluvial system and conclude that the paleogeography of the entire western Amazon region must have been characterized by this environmental setting. They also imply that therefore a long-lived lake system - or megawetland - never existed. We contend this assumption for some reasons, amongst them, the most important are: (1) this is an inconsistent overgeneralized conclusion; (2) The authors make references to previous scientific works we published which we consider incorrect, and therefore can mislead their readers.

  1. Grain Size Effects (5-63μm) of the UV-VIS-NIR Spectra of Ilmenite-Bearing Assemblages: Implications for Mapping TiO2 in the Lunar Maria

    Fine-grained particles (≤60μm) dominate the particle size distributions of many planetary surfaces. Systematic studies of particle size effects within the fine fraction have typically concentrated on transparent silicate minerals [1,2]. We have acquired a synthetic powdered ilmenite sample from Sigma-Alrich and verified the composition via X-ray diffraction and Mössbauer spectroscopy. The sample was separated into six size fractions between 5 and 63μm using ultrasonic sieving techniques (Gilson Company). Reflectance spectra, taken at RELAB, between 0.3 and 2.5μm show systematic changes in spectral contrast with particle size. A long-standing goal of the lunar science community has been the remote mapping of TiO2 abundance on the lunar surface to enable detailed studies of lunar crustal composition, surface volcanism and temporal and spatial variations in mantle composition. Returned lunar regolith samples have large variations in TiO2 abundance (0-10wt%), dominantly in the opaque oxide mineral ilmenite (FeTiO3). There is a correlation between TiO2 abundance and the ratio of ultraviolet (UV) to visible (VIS) reflectance of lunar soils but the accuracy and universal applicability of the correlation persists. Gillis-Davis and coworkers [3], demonstrated the effect of ilmenite grain size on the TiO2-UVVIS color correlation of modeled mixtures of ilmenite with low-Ti lunar mare soil for variations in ilmenite grain size from the rest of the lunar soil. They found that reducing the modeled grain size of ilmenite increased its cross sectional area and thus its spectral effectiveness. Utilizing the new ilmenite size separates we present the single scattering albedo as a function of particle size (5-63μm) in the wavelength range 0.3-2.5μm. These data can be used to improve modeled mixtures of ilmenite as a function of grain size. We show that spectral variations in ilmenite with grain size introduces scatter into the TiO2-UVVIS color correlation even if the grain size of the ilmenite is the same as the lunar soil in which it is contained. We also show that the spectral changes in ilmenite due to grain sizes will temper the magnitude of the grain size effects demonstrated by Gillis-Davis et al. [3] and makes it less likely that the UVVIS-TiO2 correlation can be explained by ilmenite alone. Grain size effects cannot explain the full range of TiO2 variability but do introduce significant scatter in UVVIS - TiO2 correlation. These findings emphasize the need to understand secondary controls on the UVVIS color of lunar soils in order to yield accurate TiO2 estimates.

    The Xolapa Complex is a metamorphic-plutonic basement that forms a large belt with more than 600 km length and 50-100 km wide along the Pacific coast of southeastern Mexico. This Complex is constituted by a high grade sequence of meta-sedimentary and meta-igneous rocks, locally migmatisized, and which are intruded by strongly deformed plutonic rocks. Because of their representative characteristics, two samples were analyzed: 1) Para-schist: this rocks present a mineral assemblage composed of biotite, sillimanite, plagioclase, k-feldspar and garnet, and 2) Amphibolite: which are constituted by amphibole, plagioclase, biotite and garnet. The garnet porphydoblasts in the para-schist are subhedral, presents retrograde compositional zoning, with almandine and pyrope rich core (Alm74-75Sps7.-10.1Pyr12.1-12.5Grs3.8-3.9) and spessartine rich rim (Alm69-71Sps14-19Pyr7.9-9.6Grs3.6-3.7). The garnet in amphibolite, presents a prograde growth zoning with a slight increase in spessartine in the core (Alm59-60Grs24-25Pyr8.0-8.3Sps7.3-7.6), and low content of spessartine component toward the rim (Alm60-62Grs23-24Pyr8.8-9.6Sps5.4-5.5). In order to constrain the P-T evolution of the region, multiequilibria thermobarometry was applied to both samples, the para-schist unit presents P-T data from 706 (ºC) and 7.5 (kbar), in the other hand the garnet amphibolite unit shows P-T data from 734 (ºC) and 7 (kbar). This study provides new geochronological data (U/Pb in zircons) for the amphibolite facies metamorphism and for the migmatitic event in the region that contributes to the understanding of the tectonic evolution of southeastern Mexico.

The network of participating institutes has a three-nation core, made up of the Netherlands Cancer Institute, the Italian European School of Molecular Medicine (SEMM) and five UK Cancer Research Institutes (The London Research Institute, The Cambridge Research Institute, The Beatson Institute for Cancer Research in Glasgow, The Patterson Institute for Cancer Research in Manchester and the MRC Gray Institute for Radiation Oncology and Biology in Oxford). The conference is hosted and organised every year by one of the core institutes; the first was in Cambridge in 2007, Amsterdam in 2008 and London in 2009, this year was the turn of Milan. In addition to the core institutes, PhD students from several other high-profile institutes are invited to attend the conference. This year participants applied from the Spanish National Cancer Centre (CNIO, Madrid), the German Cancer Research Centre (DKFZ, Heidelberg), the European Molecular Biology Labs (EMBL, Heidelberg) and the San Raffaele Institute (HSR, Milan). Moreover four ‘special guests’ from the National Centre for Biological Sciences of Bangalore (India) attended the conference in Milan. This represents a first step in widening the horizons beyond Europe into a global worldwide network of talented PhD students in life sciences.

  3. Sequence stratigraphy of continental Triassic strata of Southernmost Brazil: a contribution to Southwestern Gondwana palaeogeography and palaeoclimate

    The continental Triassic succession of southernmost Brazil comprises two second-order depositional sequences—the Sanga do Cabral (Early Triassic) and the Santa Maria (Middle to Late Triassic) supersequences. The first one includes ephemeral, low-sinuosity fluvial deposits developed on a low gradient plain. Based on fossil tetrapods, especially procolophonids, an Upper Induan age is estimated for this sequence. Facies association of the Santa Maria Supersequence indicates low-sinuosity fluvial rivers, deltas and lakes. This supersequence can be further subdivided into three third-order sequences (age provided by palaeovertebrate biostratigraphic data) as follows: Santa Maria 1 (Ladinian), Santa Maria 2 (Carnian to Early Norian) and Santa Maria 3 (probably Raethian or Early Jurassic) sequences. The Gondwanides paroxysms I and II in the Sierra de la Ventana-Cape Fold Belt are directly related to the development of both supersequences. The source area of the Sanga do Cabral Supersequence was located to the south. It consisted of an uplifted peripheral bulge situated landward of the retro-foreland system, from where older sedimentary rocks were eroded. The source area of the Santa Maria Supersequence was also positioned southwards and related to the uplifted Sul-Rio-Grandense and Uruguayan shields. The Santa Maria Supersequence stratigraphic architecture is comparable to the Triassic rift basins of Western Argentina. Diagenesis, facies and palaeontology of the studied succession suggest a dominantly semiarid climate during the Triassic.

  4. Academic freedom, public reactions, and anonymity.

    Häyry, Matti

    2014-05-01

    Academic freedom can be defined as immunity against adverse reactions from the general public, designed to keep scholars unintimidated and productive even after they have published controversial ideas. Francesca Minerva claims that this notion of strict instrumental academic freedom is supported by Ronald Dworkin, and that anonymity would effectively defend the sphere of immunity implied by it. Against this, I argue that the idea defended by Minerva finds no support in the work by Dworkin referred to; that anonymity would not in most cases effectively protect the kind of immunity sought after; and that in some cases it would not even be desirable to protect scholars from public reactions to their controversial claims.

    The aim of the present study was to investigate the volatile and sensorial profile of basil (Ocimum basilicum L.) by quantitative descriptive analysis (QDA) of the essential oil of three hybrids ("Cinnamon" × "Maria Bonita," "Sweet Dani" × "Cinnamon," and "Sweet Dani" × "Maria Bonita"). Twelve descriptive terms were developed by a selected panel that also generated the definition of each term and the reference samples. The data were subjected to ANOVA, Tukey's test, and principal component analysis. The hybrid "Cinnamon" × "Maria Bonita" exhibited a stronger global aroma that was less citric than the other samples. Hybridization favored the generation of novel compounds in the essential oil of the hybrid "Sweet Dani" × "Maria Bonita," such as canfora and (E)-caryophyllene; (E)-caryophyllene also was a novel compound in the hybrid "Sweet Dani" × "Cinnamon"; this compound was not present in the essential oils of the parents.

    Data from Apollo lunar bistatic radar experiments have been processed to give probability density functions for surface slopes. These show best agreement with a Hagfors scattering law, though data having both gaussian and exponential characteristics also exist. Surface roughness estimates range from 4 deg in maria to at least 8 deg in highlands, values which are appropriate to 25 m horizontal scales and which are areal averages over tens of square kilometers. Roughness varies with wavelength, most strongly in maria.

  17. Federico di Montefeltro's hyperkyphosis: a visual-historical case report

    PubMed Central

    D'Antoni, Anthony V; Terzulli, Stephanie L

    2008-01-01

    Introduction The literature contains several publications describing the use of visual arts to develop observational skills in medical students. Portraits of individuals of the Italian Renaissance can be used to enhance these skills and stimulate the development of differential diagnoses in medical students. The Duke of Urbino, Federico di Montefeltro (1422–1482), lost his right eye and nasal bridge during a jousting accident in 1450. Consequently, almost every profile of him in existence today depicts his face in a left lateral view. Although some authors have described the Duke's missing nasal bridge, none have described his prominent thoracic hyperkyphosis, which is clearly discernible in two paintings by Piero della Francesca. The purpose of this report is to describe the Duke's hyperkyphosis, develop relevant differential diagnoses, and suggest a possible etiology of the convexity. Case presentation We have examined two paintings of the Duke by Piero della Francesca – the diptych, The Duke and Duchess of Urbino (1465), and the Madonna of the Egg (1472). A MEDLINE search revealed 2 articles that were relevant to this study. This search was complemented by a search of the collection at the library of Seton Hall University, and the first author's experience studying at the University of Urbino. The historical data obtained from these searches were incorporated with the visual analysis to formulate a plausible etiology of the Duke's thoracic hyperkyphosis. Conclusion Differential diagnoses of the Duke's thoracic hyperkyphosis include Scheuermann disease, osteoporosis, and trauma-related spinal changes. Based on the available evidence, the Duke's thoracic hyperkyphosis could have been caused by repetitive trauma to the spine due to numerous hours on horseback with heavy armor. The role that osteoporosis played in the development of the hyperkyphosis is unclear, as is whether the Duke had the convexity during childhood. The hyperkyphosis as a stylistic variant

    Young, R. A.; Brennan, W. J.

    1976-01-01

    Crater size-frequency distributions were studied (100-500 m) and are shown to provide significant integrated information concerning mare surface ages, subsurface stratigraphy, and surficial geology. Equilibrium cratering is discussed gradually reducing the relative numbers of craters smaller than 300-400 m in diameter as surfaces age and regolith thickens. Results for surface ages are in good agreement with other published crater ages. The existing correlations of large ring structures among various circular mare basins are shown to be based on criteria that are inconsistent and nonstandardized. A means of comparing equivalent ring structures in the different maria is proposed which takes into account the important characteristics of young unflooded basins (Orientale) as well as the progressive development of tectonic and volcanic features within the older flooded maria. Specific geologic aspects of several of the lunar maria are discussed and especially Mare Smythii, because of its great age and significantly different surface morphology. Lunar photographs and maps are shown.

    Average data for igneous and/or metaigneous rocks and soils from seven lunar sites are presented. There are compositional similarities between Apollo 11 and Luna 16 eastern maria, Ap 12 and 15 western maria, and between Ap 16 and L 20 highlands. Subtle differences do exist between the paired mare sites and the two highland sites and striking differences between the eastern and western maria. Chondritic normalized REE (rare earth element) patterns for igneous rocks and soils from all sites range from 7-350 generally with negative Eu anomalies. Anorthositic gabbroes to anorthosites, presumably highland material, exhibit a positive Eu anomaly. The REE patterns or Sr isotopic ratios suggest two lava flows each for the L 16 and Ap 14 sites, at least four lava flows for the Ap 11 and 12 site and about six for the Ap 15 site.

  20. Lunar mascons - Another model and its implications

    NASA Technical Reports Server (NTRS)

    Kunze, A. W. G.

    1974-01-01

    A mascon model is proposed in which the mass excess of the mare basalts in the circular maria is supported isostatically by mass deficits at depth. The model predicts the observed positive gravity anomalies surrounded by negative ring anomalies and explains the absence of gravity anomalies over the irregular maria. The model implies that mare basalts were derived by partial melting of a source region at depth due to pressure relief resulting from the excavation of the circular mare basins, and that the crystalline residuum in the source region is of lower density than the original source rock. The trace element enrichment and near cotectic character of Apollo 11 and 12 lavas reported by some investigators may be caused by extensive magma fractionation enroute from an origin in the circular maria to the final, distant emplacement sites.

  1. Improved calibration of reflectance data from the LRO Lunar Orbiter Laser Altimeter (LOLA) and implications for space weathering

    The Lunar Orbiter Laser Altimeter (LOLA) experiment on Lunar Reconnaissance Orbiter (LRO) is a laser altimeter that also measures the strength of the return pulse from the lunar surface. These data have been used to estimate the reflectance of the lunar surface, including regions lacking direct solar illumination. A new calibration of these data is presented that features lower uncertainties overall and more consistent results in the polar regions. We use these data, along with newly available maps of the distribution of lunar maria, also derived from LRO instrument data, to investigate a newly discovered dependence of the albedo of the lunar maria on latitude (Hemingway et al., [2015]). We confirm that there is an increase in albedo with latitude in the lunar maria, and confirm that this variation is not an artifact arising from the distribution of compositions within the lunar maria, using data from the Lunar Prospector Neutron Spectrometer. Radiative transfer modeling of the albedo dependence within the lunar maria is consistent with the very weak to absent dependence of albedo on latitude in the lunar highlands; the lower abundance of the iron source for space weathering products in the lunar highlands weakens the latitude dependence to the extent that it is only weakly detectable in current data. In addition, photometric models and normalization may take into account the fact that the lunar albedo is latitude dependent, but this dependence can cause errors in normalized reflectance of at most 2% for the majority of near-nadir geometries. We also investigate whether the latitude dependent albedo may have obscured detection of small mare deposits at high latitudes. We find that small regions at high latitudes with low roughness similar to the lunar maria are not mare deposits that may have been misclassified owing to high albedos imposed by the latitude dependence. Finally, we suggest that the only modest correlations among space weathering indicators defined

  2. Fumonisin B1 and hydrolyzed fumonisin B1 (AP1) in tortillas and nixtamalized corn (Zea mays L.) from two different geographic locations in Guatemala.

    Fumonisin B1 (FB1) is a common contaminant of corn worldwide and is responsible for several diseases of animals. In the preparation of tortillas, corn is treated with lime (producing nixtamal) that when heated hydrolyzes at least a portion of the FB1 to the aminopentol backbone (AP1), another known toxin. This study analyzed the amounts of FB1 and AP1 in tortillas and nixtamal from two communities in the central highlands of Guatemala where corn is a major dietary staple (Santa Maria de Jesus, Sacatepequez, and Patzicia, Chimaltenango). The amounts of FB1 and AP1 in tortillas from Santa Maria de Jesus were, respectively, 0.85 +/- 2.0 and 26.1 +/- 38.5 microg/g dry weight (mean +/- SD), and from Patzicia were 2.2 +/- 3.6 and 5.7 +/- 9.4 microg/g dry weight. Less than 6% of the tortillas from both locations contained > or = 10 microg FB1/g dry weight; whereas, 66% of the samples from Santa Maria de Jesus and 29% from Patzicia contained > or = 10 microg AP1/g dry weight. The highest amount of AP1 (185 microg/g dry weight) was found in tortillas from Santa Maria de Jesus. The highest amounts of FB1 were 6.5 and 11.6 microg/g dry weight in tortillas from Santa Maria de Jesus and Patzicia, respectively. The mean concentration of FB1 in nixtamal was significantly higher in Santa Maria de Jesus compared to Patzicia. Surprisingly, AP1 was not detected in any of the nixtamal samples. The human impact of exposure to these amounts of fumonisins is not known. However, based on findings with other animals, where corn is a dietary staple, long-term consumption of FB1 and AP1 (especially at > or = 10 microg/g of the diet) may pose a risk to human health.

  3. Decadal and seasonal changes in temperature, salinity, nitrate, and chlorophyll in inshore and offshore waters along southeast Australia

    Sixty years of oceanographic in situ data at Port Hacking (34°S) and Maria Island (42°S) and 15 years of satellite-derived chlorophyll a (chl a) in inshore and offshore waters of southeast Australia show changes in the seasonality and trend of water properties consistent with long-term intensification and southerly extensions of East Australian Current (EAC) water. Decadal analyses reveal that the EAC extension water at Maria Island increased gradually from the 1940s to 1980s, followed by a rapid increase since the 1990s. This acceleration coincided with enhanced winter nitrate, implying increased injections of subantarctic water at Maria Island. Satellite-derived chl a at six coastal sites and offshore companion sites in the western Tasman Sea showed significant inshore-offshore variations in seasonal cycle and long-term trend. After 2004-2005, the Maria Island seasonal cycle became increasingly similar to those of Bass Strait and St. Helens, suggesting that the EAC extension water was extending further southward. Comparative analyses of inshore-offshore sites showed that the presence of EAC extension water declined offshore. Seasonal cycles at Maria Island show a recent shift away from the traditional spring bloom, toward increased winter biomass, and enhanced primary productivity consistent with extensions of warm, energetic EAC extension water and more frequent injections of cooler, fresher nitrate-replete waters. Overall, we find complex temporal, latitudinal, and inshore-offshore changes in multiple water masses, particularly at Maria Island, and changes in primary productivity that will profoundly impact fisheries and ecosystems.

  4. Science at the Breakfast Table

    1999-03-01

    The physicist Maria Goeppert Mayer and the chemist Joseph E. Mayer, during some forty years of marriage, exchanged scientific ideas continuously. We can see results of this exchange in the paths their individual intellectual careers took: Maria's from formal, mathematical atomic physics to nuclear physics informed by the phenomenological insights of a chemist, and Joe's from experimental chemistry to highly mathematical statistical mechanics. This is the kind of intellectual interaction that often goes on between scientific colleagues during the course of informal interactions, but which is rarely acknowledged since the results are often subtle shifts in scientific perspective.

  5. Major compositional units of the moon: lunar prospector thermal and fast neutrons

    1998-09-01

    Global maps of thermal and fast neutron fluxes from the moon suggest three end-member compositional units. A high thermal and low fast neutron flux unit correlates with the lunar highlands and is consistent with feldspathic rocks. The South Pole-Aitken basin and a strip that surrounds the nearside maria have intermediate thermal and fast neutron flux levels, consistent with more mafic rocks. There appears to be a smooth transition between the most mafic and feldspathic compositions, which correspond to low and high surface altitudes, respectively. The maria show low thermal and high fast neutron fluxes, consistent with basaltic rocks.

  6. Chiral symmetry, constituent quarks and quasi-elastic electron-nucleus scattering

    NASA Astrophysics Data System (ADS)

    Henley, E. M.; Krein, G.

    1989-11-01

    The effects of chiral symmetry breaking are examined for quasi-elastic electron scattering on nuclei. Nucleons are assumed to be composed of constituent quarks with masses that depend on density. This density dependence is determined on the basis of the Nambu-Jona-Lasinio model. It is found that the effects of chiral symmetry breaking are in the right direction and the right order of magnitude to explain the discrepancies between theory and experiment.

    Sjogren, W. L.; Smith, J. C.

    1976-01-01

    Six theoretical models for the mass distribution of Mare Orientale were tested using five gravity profiles extracted from radio-tracking data of orbiting spacecraft. The models with surface mass and moho relief produced the best results. Although there is a mascon-type anomaly in the central maria region, Mare Orientale is a large negative gravity anomaly. This is produced primarily by the empty ring basin. Had the basin filled with maria material it seems likely that it would have produced a mascon such as those presently existing in flooded frontside circular basins.

  8. Economic geology of lunar Helium-3

    Economic geology evaluation of lunar He-3 should answer the question: Can lunar He-3 be sold on Earth with sufficient profit margins and low enough risk to attract capital investment in the enterprise. Concepts that relate to economic geology of recovering He-3 from the lunar maria are not new to human experience. A parametric cost and technology evaluation scheme, based on existing and future data, is required to qualitatively and quantitatively assess the comprehensive economic feasibility and return on investment of He-3 recovery from the lunar maria. There are also many political issues which must be considered as a result of nuclear fusion and lunar mining.

    The presence of the Glacier Peak G ash and the underlying St. Helens Jy ash in laminated lake sediments near Marias Pass indicates that in this region the Continental Divide was ice free before about 11 400 BP. Macrofossils, pollen, and spores in these same sediments indicate establishment of shrubs, herbs, and scattered conifers by that time. At Sun River Canyon, about 90 km south of Marias Pass, presence of the Glacier Peak G ash in a postglacial alluvial fan indicates that glacial ice had receded upvalley from the canyon mouth and that the Sun River Glacier no longer existed by 11 200 BP. -from Authors

    At the Drug Information Association (DIA) 49th annual meeting, for the first time regulators (Dr Francesca Cerreta, Dr Robert Temple and Dr Yasuko Asahina) from the three International Conference on Harmonization (ICH) co-sponsor regions came together in a forum to discuss their perspective on how the aging population impacts on drug development and on the design of clinical trials. In 2010, the ICH E7 Guideline (Studies in support of Special Populations: Geriatrics) was revised with the addition of a Questions and Answers document to take into account the rapidly changing world demographics. Regulators from the three ICH regions (Europe, USA and Japan) discuss here how they foresee the application of this guideline, and the impact that this might have on new drug development and clinical trial design. This article aims to summarize the discussions at the session for the benefit of a wider audience.

    2013-05-01

    In their paper 'After-birth abortion: why should the baby live?' Alberto Giubilini and Francesca Minerva argue that because there are no significant differences between a fetus and a neonate, in that neither possess sufficiently robust mental traits to qualify as persons, a neonate may be justifiably killed for any reason that also justifies abortion. To further emphasise their view that a newly born infant is more on a par with a fetus rather than a more developed baby, Giubilini and Minerva elect to call this 'after-birth abortion' rather than infanticide. In this paper, I argue that their thesis is incorrect, and that the moral permissibility of abortion does not entail the moral permissibility of 'after-birth' abortion. PMID:23637447

    Academic freedom can be defined as immunity against adverse reactions from the general public, designed to keep scholars unintimidated and productive even after they have published controversial ideas. Francesca Minerva claims that this notion of strict instrumental academic freedom is supported by Ronald Dworkin, and that anonymity would effectively defend the sphere of immunity implied by it. Against this, I argue that the idea defended by Minerva finds no support in the work by Dworkin referred to; that anonymity would not in most cases effectively protect the kind of immunity sought after; and that in some cases it would not even be desirable to protect scholars from public reactions to their controversial claims.

    Academic freedom is an important good, but it comes with several responsibilities. In this commentary we seek to do two things. First, we argue against Francesca Minerva's view of academic freedom as presented in her article 'New threats to academic freedom' on a number of grounds. We reject the nature of the absolutist moral claim to free speech for academics implicit in the article; we reject the elitist role for academics as truth-seekers explicit in her view; and we reject a possible more moderate re-construction of her view based on the harm/offence distinction. Second, we identify some of the responsibilities of applied ethicists, and illustrate how they recommend against allowing for anonymous publication of research. Such a proposal points to the wider perils of a public discourse which eschews the calm and careful discussion of ideas. PMID:24724542

    We describe the pattern of fixations of subjects looking at figurative and abstract paintings from different artists (Molina, Mondrian, Rembrandt, della Francesca) and at modified versions in which different aspects of these art pieces were altered with simple digital manipulations. We show that the fixations of the subjects followed some general common principles (e.g., being attracted to saliency regions) but with a large variability for the figurative paintings, according to the subject's personal appreciation and knowledge. In particular, we found different gazing patterns depending on whether the subject saw the original or the modified version of the painting first. We conclude that the study of gazing patterns obtained by using the eye-tracker technology gives a useful approach to quantify how subjects observe art.

    2015-07-23

    Domain scientists need colormaps to visualize their data and are especially useful for identifying areas of interest, like in ocean data to identify eddies or characterize currents. However, traditional Rainbow colormap performs poorly for understanding details, because of the small perceptual range. In order to assist domain scientists in recognizing and identifying important details in their data, different colormaps need to be applied to allow higher perceptual definition. Visual artist Francesca Samsel used her understanding of color theory to create new colormaps to improve perception. While domain scientists find the new colormaps to be useful, we implemented a rigorous and quantitative study to determine whether or not the new colormaps have perceptually more colors. Color count data from one of these studies will be analyzed in depth in order to determine whether or not the new colormaps have more perceivable colors and what affects the number of perceivable colors.

    The aim of the present study was to investigate the volatile and sensorial profile of basil (Ocimum basilicum L.) by quantitative descriptive analysis (QDA) of the essential oil of three hybrids (“Cinnamon” × “Maria Bonita,” “Sweet Dani” × “Cinnamon,” and “Sweet Dani” × “Maria Bonita”). Twelve descriptive terms were developed by a selected panel that also generated the definition of each term and the reference samples. The data were subjected to ANOVA, Tukey's test, and principal component analysis. The hybrid “Cinnamon” × “Maria Bonita” exhibited a stronger global aroma that was less citric than the other samples. Hybridization favored the generation of novel compounds in the essential oil of the hybrid “Sweet Dani” × “Maria Bonita,” such as canfora and (E)-caryophyllene; (E)-caryophyllene also was a novel compound in the hybrid “Sweet Dani” × “Cinnamon”; this compound was not present in the essential oils of the parents.

    Rolán-Alvarez, E; Zapata, C; Alvarez, G

    1995-01-01

    The genetic structure of two sibling and sympatric species of the genus Littorina was compared using allozymic loci. The two species are biologically and ecologically well-known and mostly show similar life history characteristics. Three populations of L. mariae Sacchi & Rastelli and L. obstusata (L.) were studied in the Muros-Noya Ria (Galicia, NW Spain). In addition, four microgeographical subsamples taken from one of the populations were analysed for each species. Age, sex and genotypes for nine polymorphic loci were studied in 1250 snails of both species. L. mariae showed larger genetic population subdivision and lower heterozygosity levels for the loci studied than did L. obtusata. Heterozygote deficiencies were found in only a few cases in natural populations of both species, usually affecting the Lap-1 locus. No significant genetic differences among age or sex classes were found. These results may be explained by the lower effective population size in L. mariae than in L. obtusata. Known differences between these species in generation interval and population density during the winter can cause the different effective population sizes suggested. These life history characteristics appear to provide the most likely explanations for the differences in genetic differentiation and heterozygosity between the two species. A previously unknown L. mariae morph from exposed shores is tentatively suggested to be conspecific. PMID:7852095

  6. Length-weight relationships and biomass of the main microcrustacean species of two large tropical reservoirs in Brazil.

    PubMed

    Brito, S L; Maia-Barbosa, P M; Pinto-Coelho, R M

    2013-08-01

    Length-weight equations were determined for the main microcrustacean species of Três Marias and Furnas reservoirs (state of Minas Gerais, Brazil), and evaluated the fluctuations of their biomass. We examined the following species: Thermocyclops minutus, Bosminopsis deitersi, Bosmina hagmanni, Ceriodaphnia cornuta, and Moina minuta (Três Marias Reservoir), and Notodiaptomus henseni, Daphnia ambigua, Ceriodaphnia silvestrii, Diaphanosoma spinulosum, D. fluviatile, and Bosmina freyi (Furnas Reservoir). Dry weight was obtained in a microbalance for each size class (Cladocera) or developmental stage (Copepoda). Microcrustacean mean biomass varied from 5.76 mg DW.m(-3) and 20.36 mg DW.m(-3) (Furnas Reservoir) and from 3.75 mg DW.m(-3) and 18.14 mg DW.m(-3) (Três Marias Reservoir). Significant differences (p < 0.000) between seasons were registered with higher biomass during the rainy seasons. Thermocyclops minutus was the most important species in Três Marias, whereas in Furnas, N. henseni contributed in equal proportion. In Furnas, the higher cladoceran biomass was explained by the contribution of larger-sized species, such as D. ambigua, C. silvestrii, D. spinulosum, and D. fluviatile. Even though both reservoirs are considered oligotrophic, there were significant differences in the estimated microcrustacean biomass, which reinforces the importance of this parameter for the description of the real contribution of each species in the community.
