Preliminary analysis was made of data collected at San Nicolas Island during the Intensive Field Observation (IFO) phase of the First International Satellite Cloud Climatology Program's Regional Experiment (FIRE). Of particular interest was an examination of a distinct diurnal variation in the cloud properties, despite an apparent absence of diurnal forcing from the surface. Direct or indirect radiative modulation of such clouds, as proposed by Fravalo at el. (1981) and Turton and Nicholls (1987) indeed seems likely. Preliminary observational evidence for diurnal change in the marine stratocumulus adjacent to San Nicolas Island is presented. A comparison is then made between the observed behavior and predictions from theoretical models of the interactive effect of radiation on boundary layer clouds.

Homosexuality: representing the devil or a spiritual gift? Two opposing views in the same Marian devotion.

This article analyzes opposing discourses on homosexuality forwarded by two different Catholic social actors. These are linked to the messages of the Lady of All Nations, a Marian apparition site in Amsterdam. These different actors are understood as competing moral communities ( Hunt, 2009 ), especially about the issue of what constitute European values. Both discourses can be seen as examples of the minoritizing yet universalizing view on homosexuality ( Kosofsky Sedgwick, 1990 , p. 85). The devotion to the Lady of All Nations serves as a site for promoting competing discourses ( Hermkens, Jansen, & Notermans, 2009 ).

Legends about Legends: Abraham Eleazar's Adaptation of Nicolas Flamel.

PubMed

Priesner, Claus

2016-02-01

This paper explores the relationship between three illustrated alchemical treatises, all of which are associated with Jewish adepts: the famous Le Livre des figures hieroglyphiques attributed to Nicolas Flamel, and two treatises published in 1735 in Erfurt-the Uraltes Chymisches Werckh and the Donum Dei. The Werckh is supposedly written by Rabbi Abraham Eleazar, while the Donum Dei is attributed to an ancient alchemist-cabalist, Rabbi Samuel Baruch. I argue that these authors are fictitious, and that both works were in fact written in the early eighteenth century by their supposed editor, the probably pseudonymous Julius Gervasius. Gervasius connects the Werckh with the legend of Nicolas Flamel by suggesting that it is based on the original, Jewish manuscript which helped Flamel to find the Stone of the Sages. Gervasius used various strategies to confer a sense of Jewish "authenticity" on these works, borrowing from contemporary (non-Jewish) perceptions of Jewish ritual, Hebrew language, and Christian Cabala. The Werckh also borrows and adapts a sequence of allegorical illustrations from those in pseudo-Flamel's Livre, and I compare the two sets of figures and, where possible, interpret them. I conclude that the later works in fact teach us far more about the state of alchemy in the seventeenth and eighteenth centuries than they do about either medieval alchemy or Judaism.

Stability and change in kelp forest habitats at San Nicolas Island

Kenner, Michael C.; Tinker, M. Tim

Kelp forest communities are highly variable over space and time. Despite this complexity it has been suggested that kelp forest communities can be classified into one of 2 states: kelp dominated or sea urchin dominated. It has been further hypothesized that these represent “alternate stable states” because a site can remain in either of these states for decades before some perturbation causes a rapid shift to the other state. Our research group has maintained a subtidal community monitoring program for 38 years at San Nicolas Island consisting of twice-annual scuba-based surveys at 6 sites distributed within 4 regions around the island. Three types of perturbations are thought to be relevant to subtidal community dynamics at San Nicolas: (1) physical disturbances in the form of major storm and El Niño/Southern Oscillation (ENSO) events; (2) invertebrate diseases, which periodically decimate urchin populations; and (3) the reintroduction and subsequent increase of sea otters (Enhydra lutris nereis). These 3 perturbations differ in spatial and temporal specificity; physical disturbances and disease outbreaks occur periodically and could affect all 4 regions, while sea otter predation has been concentrated primarily at the West End sites over the last 15 years. The different types of perturbations and the duration of the time series at the kelp forests at San Nicolas make the data set ideal for testing the “alternate stable state” hypothesis. We use nonmetric multidimensional scaling (NMDS) to examine spatial and temporal patterns of community similarity at the 4 regions. In particular, we evaluate support for the existence of stable states, which are represented on NMDS plots as distinct spatial clusters. Community dynamics at each site approximated a biased random walk in NMDS space, with one or more basins of attraction and occasional jumps between basins. We found evidence for alternative stable states at some sites, and we show that transitions from one

Nicola Cusano e il foro astronomico al castello di Andraz

de Dona', G.

Cardinal Nicolas from Cues (1401-1464) was friend of Paolo Toscanelli and one of the first supporters of heliocentrism. He carved a tube in the south western wall of a room of the castle of Andraz. It was possibly used to calculate the date of the winter solstice, in order to evaluate the corrections needed to the Julian calendar then in use. The astronomical use of this tube is described. The accuracy achievable in the measurement of the solstice is surprising. It is possible that the tubes made by Gerbert of Aurillac (945-1003) were used with similar awareness.

Gender and morals in Spanish Catholic youth culture: a case study of the Marian Congregations 1930-1936.

PubMed

Vincent, M

2001-01-01

Jesuit-run Marian Congregations proliferated in 1930s Spain. Drawing on literature produced for their members, this article demonstrates how gendered understandings were fundamental to the congregations' symbolic delineation of an uncontaminated Catholic space. Visions of an incorrupt male elite abound, reinforcing the Jesuits' educational mission among future leaders and opinion-formers. In contrast, the purity of women and children was seen as a sign of society's moral health. Modesty was the quintessential female virtue. Yet, the cult of the Virgin Mary suggested that the virginal female body was both tool and symbol in the struggle against a fallen world. Girls were, therefore, charged with the task of moral guardianship. Such campaigns were emblematic of Spanish Catholicism's tendency to proffer religious solutions to social problems.

Pierre-François Nicolas, was born in Saint-Mihiel in 1743, studied in this town and in St-Nicolas-de-Port near Nancy. At first he has been a military apothecary during the "Guerre de Sept-Ans". Then he studied pharmacy in Nancy and was received in 1768 at the "Maîtrise de pharmacie". With the physician Henri Michel du Tennatar, he created a teaching of chemistry for medicine students and became the professor of chemistry of the Faculty of Medicine in 1781. During these years, he published some research results about hydrology, distillery, biochemistry (phosphorus in bone), toxicology, dyeing... At the end of 1783, he succeeded in the realization of a balloon and he played an important part in Nancy during the French Revolution. Professor at the "Ecole de médecine" in Strasbourg for some weeks, then in Nancy at the "Ecole centrale" and at the "Société de santé", he left Nancy towards the mid-1798. Staying in Paris for two or three years he probably worked with Fourcroy and perhaps Chaptal and Berthollet. In the early years of the nineteenth century he was appointed professor in the "Ecole centrale" du Calvados" and some years after at the "Faculté des sciences" in Caen. His latest significant work with Gueudeville was devoted to the detection of sugar in the urine of diabetic patients. Retired in 1811 Pierre-François Nicolas died in Caen in 1816.

2014-10-01

This paper presents an analysis of scientific creation of the brilliant Romanian scientist Nicolae Donici, as well as of his life, from the point of view of unity and struggle of opposites in his life and creation. It is shown that the scientific activities of the scientist are at the interface between astronomy and astrophysics, between the fundamental research and engineering, the great fundamental realizations being impossible without putting into operation of the observatory at the motherland of the scientist in Dubasari Vechi, Bassarabia. The events in the life of the scientist ranged between misfortunes and challenges from the one hand, and lucky circumstances and achievements on the other hand. The confrontations between wealth and poverty, between blows of fate and willingness to confront challenges in the life of the great scientist are also of the dialectic. As the great scientist’s life is marked by contrasts and opposites, the attitude towards him also was between the admiration and contempt during the life and between gratitude and oblivion after his death.

Operant psychology goes to the fair: Marian and Keller Breland in the popular press, 1947-1966

Marian and Keller Breland pioneered the application of operant psychology to commercial animal training during the 1940s and 1950s. The Brelands' story is relatively unknown in the history of behavior analysis. Using information from the Breland-Bailey papers, this paper describes the development and activities of Animal Behavior Enterprises (ABE), the Brelands' animal training business. We also review popular press coverage of the Brelands between 1947 and 1966 to investigate the level of public exposure to ABE-trained animals and to the principles and methods of operant psychology. An examination of 308 popular print articles featuring the Brelands indicates that there was public exposure of behavior analysis through the popular press coverage of ABE-trained animals. Furthermore, the expansion of operant methods to the marine mammal and bird training industries can be linked to the Brelands' mass media exposure.

Dense populations of black abalones (Haliotis cracherodii Leach) were monitored in permanent intertidal plots at nine sites on San Nicolas Island from 1981 through 1990. Densities were essentially constant at all four sites along the north shore of the island throughout the study period. Densities at five sites along the south shore were more variable, possibly reflecting asynchronous variation in recruitment, mortality resulting from wave disturbance, and removal by people. Temporal variation of abalone densities apparently was not influenced by sea otters or abalone withering syndrome during this study. Abalones were strongly aggregated in space. Highest densities occurred in areas of irregular substrata, apparently as a result of preference for crevices and vertical faces. The locations of dense patches were persistent in time.

San Nicolas Island is surrounded by broad areas of shallow subtidal habitat, characterized by dynamic kelp forest communities that undergo dramatic and abrupt shifts in community composition. Although these reefs are fished, the physical isolation of the island means that they receive less impact from human activities than most reefs in Southern California, making San Nicolas an ideal place to evaluate alternative theories about the dynamics of these communities. Here we present monitoring data from seven sampling stations surrounding the island, including data on fish, invertebrate, and algal abundance. These data are unusual among subtidal monitoring data sets in that they combine relatively frequent sampling (twice per year) with an exceptionally long time series (since 1980). Other outstanding qualities of the data set are the high taxonomic resolution captured and the monitoring of permanent quadrats and swaths where the history of the community structure at specific locations has been recorded through time. Finally, the data span a period that includes two of the strongest ENSO events on record, a major shift in the Pacific decadal oscillation, and the reintroduction of sea otters to the island in 1987 after at least 150 years of absence. These events provide opportunities to evaluate the effects of bottom-up forcing, top-down control, and physical disturbance on shallow rocky reef communities.

This article describes the work of Dr. Antoni Marian Gabryszewski, orthopaedic surgeon, associate professor at Lvov University, towards the development of orthopaedics and rehabilitation in Poland before World War I. It is based on archival materials, publications in medical journals and articles from the daily press of that time. The author presents little-known facts concerning Dr. Gabryszewski's occupational and academic activity and his work at the Surgery Dept. of Lvov University as well as his habilitation dissertation, regarded as the first attempt to position orthopaedics as distinct from surgery in Poland. The article also describes his long-term work at the private Orthopaedic Facility established in 1898 in Lvov which later incorporated the Zander Institute in 1908. The Zander Institute was the first in Galicia to offer exercise machines designed by Dr. Gustav Zander, imported from Stockholm and enjoying an extraordinary popularity in the world. Dr. Gabryszewski's practice as a spa doctor, which he pursued in Iwonicz Zdrój in the summer months, is also presented. Dr. A. Gabryszewski introduced comprehensive rehabilitation to the treatment of orthopaedic patients both at the Surgery Dept. of Lvov University and at his Orthopaedic Facility. He used therapeutic gymnastics (particularly mechanotherapy), therapeutic massage, physical therapy and orthopaedic aids. Analysis of the source materials leads to unequivocal conclusions attesting to Dr. A. Gabryszewski's pioneering role and significant contribution to the development of orthopaedics and rehabilitation in Poland.

Lithogenic and biogenic particle deposition in an Antarctic coastal environment (Marian Cove, King George Island): Seasonal patterns from a sediment trap study

Particulate suspended material was recovered over a 23-month period using two sediment traps deployed in shallow water (˜30 m deep) off the King Sejong Station located in Marian Cove of King George Island, West Antarctica. Variability in seasonal flux and geochemical characteristics of the sediment particles highlights seasonal patterns of sedimentation of both lithogenic (terrigenous) and biogenic particles in the coastal glaciomarine environment. All components including total mass flux, lithogenic particle flux and biogenic particle flux show distinct seasonal variation, with high recovery rates during the summer and low rates under winter fast ice. The major contributor to total mass flux is the lithogenic component, comprising from 88% during the summer months (about 21 g m -2 d -1) up to 97% during the winter season (about 2 g m -2 d -1). The lithogenic particle flux depends mainly on the amount of snow-melt (snow accumulation) delivered into the coastal region as well as on the resuspension of sedimentary materials. These fine-grained lithogenic particles are silt-to-clay sized, composed mostly of clay minerals weathered on King George Island. Biogenic particle flux is also seasonal. Winter flux is ˜0.2 g m -2 d -1, whereas the summer contribution increases more than tenfold, up to 2.6 g m -2 d -1. Different biogenic flux between the two summers indicates inter-annual variability to the spring-summer phytoplankton bloom. The maximum of lithogenic particle flux occurs over a short period of time, and follows the peak of biogenic particle flux, which lasts longer. The seasonal warming and sea-ice retreat result in change in seawater nutrient status and subsequent ice-edge phytoplankton production. Meanwhile, the meltwater input to Marian Cove from the coastal drainage in January to February plays a major role in transporting lithogenic particles into the shallow water environment, although the tidal currents may be the main agents of resuspension in this

In an effort to gain geohydrologic knowledge and to increase the availability of ground water to the U.S. Navy on San Nicolas Island, nine test wells were drilled by the U.S. Geological Survey in 1989 and one production well was drilled by the U.S. Navy in 1990. One of the nine test wells was dry, five produced less than 10 gallons of water per day, two produced between 20 and 30 gallons per day, and one produced 400 gallons per day. The production well produced about 900 gallons per day. Water samples were collected from eight wells during 1989-90 and analyzed for concentrations of major dissolved inorganic ions and nutrients. Five of the sampled wells were constructed in 1989, one was constructed in 1990, and two were constructed prior to 1989. Data from the study are presented in tables and graphs. Included are geophysical, lithologic, and well-construction data and results obtained from well-pumping tests and from the chemical analysis of water from selected wells.

Annual and Spatial Variation of the Kelp Forest Fish Assemblage at San Nicolas Island, California

1993-01-01

The kelp forest fishes of San Nicolas Island, California were studied from 1981-1986 to examine the causes of among-site and among-year variation in the fish assemblages. Fish counts and seven physical and biological variables were recorded at six sites around the island every spring and fall. Over the study period, a total of 45 fish species from 18 families were recorded, though members of nive families dominated at all sites. Among-site variation was considereable with two sites on the south side of the island having two to four times as many non-schooling fishes as the other four sites. Three variables, based on stepwise multiple regression techniques, were important predictors of site-specific fish abundance: 1) vertical relief; 2) sand cover and 3) understory algal cover. The total number of fishes varied interannually by a factor of three. Due to recruitment occuring each spring, there was a strong seasonal component to the variation in fish abundance. The extent of seasonal and interannual variaton of fish abundance is an indication of the variable nature of recruitment to this area. Over the 6 yr period, there were three distinct groupings of fish assemblages correspondong to pre- (Fall 1981 - Fall 1982), during spring (Spring 1983 - Spring 1984) and post El Nino (Fall 1984 - Fall 1986) sampling dates. During El Nino sampling period, there was considerable recruitment of southern affinity fish species, increasing both the abundance and diversity of the fish assemblages. Large-scale oceanographic processes, coupled with site-specific features of the reef habitat, produce a moderately diverse, though relatively abundant fish fauna at San Nicolas Island.

Searching for remains of a observation platform (pavimentum) of Nicolas Copernicus's astronomical instruments

St. Stanislas's canonry in Frombork (northern Poland) was the last place of residence of the famous astronomer Nicolas Copernicus (1473-1543). It is very probable that he conducted his astronomical observations from the garden using so-called pavimentum to arrange his instruments. Copernicus's pavimentum was a 2 by 1.5m pedestal, probably a floor based on a brick foundation with a rail. Ground penetrating radar examinations were carried out in the canonry's garden in January 2009 to obtain 3-D model of the 2 meter thick upper part of sediments and resulted in recognition of stratigraphy of the site and allowed to find some anomalies which are suspected to be a human origin. The analysis of historical sources enabled the researchers to limit the study area to a plot of land at the back of the St. Stanislaw's canonry building. As a result, the GPR probing was undertaken on the rectangular plot of ground of 43 m by 95 m, located to the south west of the canonry building. The searched object was a kind of a pavement, possibly made of bricks or stone and bricks, and the size from 1.5 m by 2 m, to 4 m by 4 m, or even 7 m by 3 m. During the field research the impulse GPR SIR SYSTEM-2000 GSSI™ was used. For the profiling a monostatic 400MHz central frequency antenna was used. The selected value of the dielectric constant was 15, which represents the velocity of 7.7 cm/ns of the electromagnetic wave propagation in the deposit. In practice this means that in the study area the vertical scale of the returning electromagnetic wave includes about 2.3 m (60 ns) of the deposit of diverse graining with a large content of humus and debris. The horizontal scale was measured in the real time with the use of the GSSI survey wheel. The construction of the three-dimensional block of the deposit was based on 95 vertical cross-sections at one-meter spaces and the SE-NW course. As a result, the 3-D model showed the horizontal extends of the geophysical anomalies. The GPR studies have

Analysis of the 8 July 1987 (Julian Day 189) tethered balloon flight from San Nicolas Island is summarized. The flight commenced at about 14:30 UTC (7:30 Pacific Daylight Time) and lasted six and one-half hours. The position of the Colorado State University (CSU) instrument package as a function of time is shown. For the purpose of presentation of results, researchers divided the flight into 13 legs. These legs consist of 20 minute constant level runs, with the exception of leg 1, which is a sounding from the surface to just above 930 mb. The laser ceilometer record of cloud base is also shown. The cloud base averaged around 970 mb during much of the flight but was more variable near the end. Before the tethered balloon flight commenced, a Communications Link Analysis and Simulation System (CLASS) sounding was released at 12:11 UTC (5:11 PDT). Temperature and moisture data below 927 mb for this sounding is shown. The sounding indicates a cloud top around 955 mb at this time.

Metamorphosis and the aesthetics of loss: I. Mourning Daphne--the Apollo and Daphne paintings of Nicolas Poussin.

PubMed

Tutter, Adele

2011-04-01

The myth of Apollo and Daphne, as told in Ovid's Metamorphoses, is viewed through the self-referential eye of the seicento painter, Nicolas Poussin. Collectively, the tree-metaphoric myths are argued to metaphorically represent, mourn, and negate unbearable realities, including the developmental challenges of adolescence and adulthood - in particular, loss. Examined in the context of their aesthetic precedents and a close reading of Ovid 's text, the two Apollo and Daphne paintings that bracket Poussin's oeuvre are interpreted as conveying the conflict and ambiguity inherent to Ovid, as well as connotations more personal to the artist. The poetic and aesthetic reworking of the regressive, magical experience of metamorphosis restores it to the symbolic world of metaphor: for reparation, remembrance, and return.

San Nicolas Island, California has one of the best records of fossiliferous Quaternary marine terraces in North America, with at least fourteen terraces rising to an elevation of ~270 m above present-day sea level. In our studies of the lowest terraces, we identified platforms at 38-36 m (terrace 2a), 33-28 m (terrace 2b), and 13-8 m (terrace 1). Uranium-series dating of solitary corals from these terraces yields three clusters of ages: ~120 ka on terrace 2a (marine isotope stage [MIS] 5.5), ~120 and ~100 ka on terrace 2b (MIS 5.5 and 5.3), and ~80 ka (MIS 5.1) on terrace 1. We conclude that corals on terrace 2b that date to ~120 ka were reworked from a formerly broader terrace 2a during the ~100 ka sea stand. Fossil faunas differ on the three terraces. Isolated fragments of terrace 2a have a fauna similar to that of modern waters surrounding San Nicolas Island. A mix of extralimital southern and extralimital northern species is found on terrace 2b, and extralimital northern species are on terrace 1. On terrace 2b, with its mixed faunas, extralimital southern species, indicating warmer than present waters, are interpreted to be from the ~120 ka high sea stand, reworked from terrace 2a. The extralimital northern species on terrace 2b, indicating cooler than present waters, are interpreted to be from the ~100 ka sea stand. The abundant extralimital northern species on terrace 1 indicate cooler than present waters at ~80 ka. Using the highest elevations of the ~120 ka platform of terrace 2a, and assuming a paleo-sea level of +6 m based on previous studies, San Nicolas Island has experienced late Quaternary uplift rates of ~0.25-0.27 m/ka. These uplift rates, along with shoreline angle elevations and ages of terrace 2b (~100 ka) and terrace 1 (~80 ka) yield relative (local) paleo-sea level elevations of +2 to +6 m for the ~100 ka sea stand and -11 to -12 m for the ~80 ka sea stand. These estimates are significantly higher than those reported for the ~100 ka and ~80 ka

Thomas-Nicolas Larcheret, teacher in singing, declamation, guitar or lyre and violin, author of music and books, but also inventor of the universal elixir by his name, is a good example of quack of the 19th century. His book Larcheregium ou Dictionnaires spéciaux de mon élixir, ainsi que toute ma doctrine et de mes adhérens (Larcheregium or special Dictionaries of my elixir, as well as all my doctrine and my adherents), published in 1819, deserves a deep study to show the most frequently used arguments by the ones who emphasize the value of their secret remedy. The opportunities are there to present themselves as victims of medical authorities, experts and authorities as a whole, that do not recognize the value of their product. The only acceptable judge for them is the experience reported by the patients who are able to demonstrate the efficacy of the product since they do buy it (probably at a very high price). From this viewpoint, the book of Larcheret is a good example of turning the authorities down and of diatribe against physicians and pharmacists. It is also the demonstration that, even with the Empire's new regulations against secret remedies and quacks, they will still persist for a large part of the 19th century in France.

Evidence of repeated wildfires prior to human occupation on San Nicolas Island, California

Understanding how early humans on the California Channel Islands might have changed local fire regimes requires a baseline knowledge of the frequency of natural wildfires on the islands prior to human occupation. A sedimentary sequence that was recently discovered in a small canyon on San Nicolas Island contains evidence of at least 24 burn events that date to between ~37 and 25 ka (thousands of calibrated 14C years before present), well before humans entered North America. The evidence includes abundant macroscopic charcoal, blackened sediments, and discrete packages of oxidized, reddish-brown sediments that are similar in appearance to sedimentary features called “fire areas” on Santa Rosa Island and elsewhere. Massive fine-grained sediments that contain the burn evidence are interpreted as sheetwash deposits and are interbedded with coarse-grained, clast-supported alluvial sediments and matrix supported sands, pebbles, and cobbles that represent localized debris flows. These sedimentary sequences suggest that the catchment area above our study site underwent multiple cycles of relative quiescence that were interrupted by fire and followed by slope instability and mass wasting events. Our 14C-based chronology dates these cycles to well before the arrival of humans on the Channel Islands and shows that natural wildfires occurred here, at a minimum, every 300–500 years prior to human occupation.

The temporal evolution of the structure of the marine boundary layer and of the associated low-level clouds observed in the vicinity of the San Nicolas Island (SNI) is defined from data collected during the First ISCCP Regional Experiment (FIRE) Marine Stratocumulus Intense Field Observations (IFO) (July 1 to 19). Surface, radiosonde, and remote-sensing measurements are used for this analysis. Sounding from the Island and from the ship Point Sur, which was located approximately 100 km northwest of SNI, are used to define variations in the thermodynamic structure of the lower-troposphere on time scales of 12 hours and longer. Time-height sections of potential temperature and equivalent potential temperature clearly define large-scale variations in the height and the strength of the inversion and periods where the conditions for cloud-top entrainment instability (CTEI) are met. Well defined variations in the height and the strength of the inversion were associated with a Cataline Eddy that was present at various times during the experiment and with the passage of the remnants of a tropical cyclone on July 18. The large-scale variations in the mean thermodynamic structure at SNI correlate well with those observed from the Point Sur. Cloud characteristics are defined for 19 days of the experiment using data from a microwave radiometer, a cloud ceilometer, a sodar, and longwave and shortwave radiometers. The depth of the cloud layer is estimated by defining inversion heights from the sodar reflectivity and cloud-base heights from a laser ceilometer. The integrated liquid water obtained from NOAA's microwave radiometer is compared with the adiabatic liquid water content that is calculated by lifting a parcel adiabatically from cloud base. In addition, the cloud structure is characterized by the variability in cloud-base height and in the integrated liquid water.

The biological soil crusts of the San Nicolas Island: Enigmatic algae from a geographically isolated ecosystem

Flechtner, V.R.; Johansen, J.R.; Belnap, J.

2008-01-01

Composite soil samples from 7 sites on San Nicolas Island were evaluated quantitatively and qualitatively for the presence of cyanobacteria and eukaryotic microalgae. Combined data demonstrated a rich algal flora with 19 cyanobacterial and 19 eukaryotic microalgal genera being identified, for a total of 56 species. Nine new species were identified and described among the cyanobacteria and the eukaryotic microalgae that were isolated: Leibleinia edaphica, Aphanothece maritima, Chroococcidiopsis edaphica, Cyanosarcina atroveneta, Hassallia californica, Hassallia pseudoramosissima, Microchaete terrestre, Palmellopsis californiens, and Pseudotetracystis compactis. Distinct distributional patterns of algal taxa existed among sites on the island and among soil algal floras of western North America. Some algal taxa appeared to be widely distributed across many desert regions, including Microcoleus vaginatus, Nostoc punctiforme, Nostoc paludosum, and Tolypothrix distorta, Chlorella vulgaris, Diplosphaera cf. chodatii, Myrmecia astigmatica, Myrmecia biatorellae, Hantzschia amphioxys, and Luticola mutica. Some taxa share a distinctly southern distribution with soil algae from southern Arizona, southern California, and Baja California (e.g., Scenedesmus deserticola and Eustigmatos magnus). The data presented herein support the view that the cyanobacterial and microalgal floras of soil crusts possess significant biodiversity, much of it previously undescribed.

Island foxes (Urocyon littoralis) are a species of conservation concern that occur on six of the Channel Islands off the coast of southern California. We analysed island fox diet on San Nicolas Island during 2006–12 to assess the influence of the removal of feral cats (Felis catus) on the food use by foxes. Our objective was to determine whether fox diet patterns shifted in response to the cat removal conducted during 2009–10, thus indicating that cats were competing with foxes for food items. We also examined the influence of annual precipitation patterns and fox abundance on fox diet. On the basis of an analysis of 1975 fox scats, use of vertebrate prey – deer mice (Peromyscus maniculatus), birds, and lizards – increased significantly during and after the complete removal of cats (n = 66) from the island. Deer mouse abundance increased markedly during and after cat removal and use of mice by foxes was significantly related to mouse abundance. The increase in mice and shift in item use by the foxes was consistent with a reduction in exploitative competition associated with the cat removal. However, fox abundance declined markedly coincident with the removal of cats and deer mouse abundance was negatively related to fox numbers. Also, annual precipitation increased markedly during and after cat removal and deer mouse abundance closely tracked precipitation. Thus, our results indicate that other confounding factors, particularly precipitation, may have had a greater influence on fox diet patterns.

Increases in deep ocean ambient noise in the Northeast Pacific west of San Nicolas Island, California.

2006-08-01

Recent measurement at a previously studied location illustrates the magnitude of increases in ocean ambient noise in the Northeast Pacific over the past four decades. Continuous measurements west of San Nicolas Island, California, over 138 days, spanning 2003-2004 are compared to measurements made during the 1960s at the same site. Ambient noise levels at 30-50 Hz were 10-12 dB higher (95% CI = 2.6 dB) in 2003-2004 than in 1964-1966, suggesting an average noise increase rate of 2.5-3 dB per decade. Above 50 Hz the noise level differences between recording periods gradually diminished to only 1-3 dB at 100-300 Hz. Above 300 Hz the 1964-1966 ambient noise levels were higher than in 2003-2004, owing to a diel component which was absent in the more recent data. Low frequency (10-50 Hz) ocean ambient noise levels are closely related to shipping vessel traffic. The number of commercial vessels plying the world's oceans approximately doubled between 1965 and 2003 and the gross tonnage quadrupled, with a corresponding increase in horsepower. Increases in commercial shipping are believed to account for the observed low-frequency ambient noise increase.

NRL tethered balloon measurements at San Nicolas Island during FIRE IFO 1987

An overview is given of the tethered balloon measurements made during the First ISCCP Regional Experiment (FIRE) marine stratocumulus intensive field observations (IFO) at San Nicolas Island in 1987. The instrument utilized on the balloon flights, the 17 flights over a 10 day period, the state of the data analysis, and some preliminary results are described. A goal of the measurements with the Naval Research Laboratory (NRL) balloon was to give a unique and greatly improved look at the microphysics of the clear and cloud-topped boundary layer. For this goal, collocated measurements were made of turbulence, aerosol, cloud particles, and meteorology. Two new instruments which were expected to make significant contributions to this effort were the saturation hygrometer, capable of measuring 95 percent less than RH 105 percent (with an accuracy of 0.05 percent near 100 percent) and used for the first time in clouds; and the forward scatter meter which gives in situ LWC measurements at more than 10 Hz. The data set, while unfortunately only partially simultaneous with the bulk of the FIRE stratocumulus observations, is unique and worthwhile in its own right. For the first time accurate RH measurements near 100 percent have been made in-cloud; although, the use of the saturation hygrometer reflected a learning experience which will result is substantially better performance the next time. These measurements were made in conjunction with other microphysical measurements such as aerosol and cloud droplet spectra, and perhaps most important of all, they were all collocated with bivane turbulence measurements thus permitting flux calculations. Thus the analysis of this data set, which consisted of about 50 percent stratocumulus cases including increasing and decreasing partial cloud cover, should lead to new insights on the physical mechanisms which drive the boundary-layer/cloud/turbulence system.

Mesoscale variability of free tropospheric humidity near San Nicolas Island during FIRE

White, A. B.; Fairall, C. W.; Thomson, D. W.

1990-01-01

Humidity variability at the top of the marine boundary layer (MBL) and in the free troposphere was examined using a variety of measurements taken on and around San Nicolas Island (SNI) during the FIRE IFO in July, 1987. Doppler wind profiler reflectivity recorded at two minute time resolution has provided the most continuous record and detail of small scale humidity fluctuations. Rawinsonde data were available from both an island site and the research vessel Point Sur. The information extractable from these sources is somewhat limited due to the frequency of launches (3 to 4/day at SNI and 6/day on the Point Sur). Some additional data were available from instrumented aircraft although scheduling flights in the neighborhood of the island was difficult due to restrictions on the air space. Other relevant data were collected at SNI near the radar and rawinsonde launch sites. A continuous record of cloud base altitude was logged by a ceilometer. Doppler acoustic sounder (sodar) reflectivity data provided a good record of inversion height. The sodar also monitored turbulent temperature fluctuations in the MBL. A small ground station recorded hourly averages of solar irradiance and downward longwave irradiance. The analysis in progress of the various data sets for two adjacent two day periods from 11 July to 14 July is described. The earlier period was chosen because the marine inversion was unusually high and there was increased frequency of rawinsonde launches at SNI. The later period was chosen because of the significant descent with time of an elevated inversion indicated by the radar data. Throughout the four day period, but especially in the first half, the turbulent humidity structure calculated from Doppler radar reflectivity shows excellent agreement with humidity profiles evaluated from rawinsonde data.

The construction of the idea of the city in Early Modern Europe: Pérez de Herrera and Nicolas Delamare.

PubMed

Fraile, Pedro

2010-01-01

With the economic and social changes in Europe at the end of the sixteenth century and the formation and consolidation of an urban network throughout the continent, questions such as poverty, sanitation, and hygiene began to pose acute problems in the cities of the age. A new school of thought, known in Spain as Ciencia de Policía and in the Mediterranean area as Policy Science, proposed solutions for these problems and tested them through practical interventions inside the urban setting. In this article the author compares the work of two thinkers: Cristóbal Pérez de Herrera, a Spaniard, and Nicolas Delamare, a Frenchman. Writing in the late sixteenth and early seventeenth centuries, Pérez de Herrera examined the organization of Madrid, the newly founded (though still not firmly established) capital of Spain. Delamare based his study on the Paris of the early eighteenth century. The author stresses the coincidences in some of the ideas of both thinkers and shows how their writings begin to embody a new idea of the city, many aspects of which have survived until the present day.

The painting Rebecca and Eliezer at the Well, which hangs in the Fitzwilliam Museum, Cambridge, UK, is possibly one of the last figure painting executed by Nicolas Poussin at the very end of his life and is usually dated to the early 1660s. In this perspective special feature, Philippe Walter, Alain Brunelle and colleagues give new insights on the artist's working methods by a careful stateof-the-art imaging ToF-SIMS study of one sample taken on the edge of the painting. This approach allowed for the identification of the pigments used in the painting, their nature and components and those of the ground and preparatory layers, with the identification of the binder(s) and possible other additions of organic materials such as glue. This study paves the way to a wider use of ToF-SIMS for the analysis of ancient cultural heritage artefacts. Dr. Walter is the Director of the Molecular and Structural Archeology Laboratory (Université Pierre et Marie Curie, Paris, France). Dr. Brunelle is Head of the Mass Spectrometry Laboratory at the Institut de Chimie des Substances Naturelles (CNRS, Gif-sur-Yvette, France). Their long standing collaboration has led to several seminal publications on the analysis of ancient artefacts by mass spectrometry. Copyright © 2016 John Wiley & Sons, Ltd.

Plastic surgery in 17th century Europe. case study: Nicolae Milescu, the snub-nosed.

PubMed

Dumbravă, Daniela; Luchian, Stefan

2013-01-01

The rising and the existence of plastic and aesthetic surgery in early modern Europe did not have a specific pattern, but was completely different from one nation to another. Colleges of Physicians could only be found in some places in Europe; different Parliaments of Europe's nations did not always elevate being a surgeon to the dignity of a profession, and being a surgeon did not always come with corporate and municipal privileges, or with attractive stipends. Conversely, corporal punishments for treacherous surgeons were ubiquitous. Rhinoplasty falls into the category of what Ambroise Paré named "facial plastic surgery". The technique is a medical source from which many histories derive, one more fascinating than the other: the history of those whose nose was cut off (because of state betrayal, adultery, abjuration, or duelling with swords), the history of those who invented the surgery of nose reconstruction (e.g. SuSruta-samhita or Tagliacozzi?), the history of surgeries kept secret in early modern Europe (e.g. Tropea, Calabria, Leiden, Padua, Paris, Berlin), and so on. Where does the history of Nicolae Milescu the Snub-nosed fall in all of this? How much of this history do the Moldavian Chronicles record? Is there any "scholarly gossip" in the aristocratic and diplomatic environments at Constantinople? What exactly do the British ambassadors learn concerning Rhinoplasty when they meet Milescu? How do we "walk" within these histories, and why should we be interested at all? What is their stike for modernity? Such are the interrogations that this article seeks to provoke; its purpose is to question (and eventually, synchronise) histories, and not exclusively history, both in academic terms but also by reassessing the practical knowledge of the 17th century.

A cache feature salvaged from an eroding sea cliff on San Nicolas Island produced two redwood boxes containing more than 200 artifacts of Nicoleño, Native Alaskan, and Euro-American origin. Outside the boxes were four asphaltum-coated baskets, abalone shells, a sandstone dish, and a hafted stone knife. The boxes, made from split redwood planks, contained a variety of artifacts and numerous unmodified bones and teeth from marine mammals, fish, birds, and large land mammals. Nicoleño-style artifacts include 11 knives with redwood handles and stone blades, stone projectile points, steatite ornaments and effigies, a carved stone pipe, abraders and burnishing stones, bird bone whistles, bone and shell pendants, abalone shell dishes, and two unusual barbed shell fishhooks. Artifacts of Native Alaskan style include four bone toggling harpoons, two unilaterally barbed bone harpoon heads, bone harpoon fore-shafts, a ground slate blade, and an adze blade. Objects of Euro-American origin or materials include a brass button, metal harpoon blades, and ten flaked glass bifaces. The contents of the cache feature, dating to the early-to-mid nineteenth century, provide an extraordinary window on a time of European expansion and global economic development that created unique cultural interactions and social transformations.

Horizontal variability of the marine boundary layer structure upwind of San Nicolas Island during FIRE, 1987

NASA Technical Reports Server (NTRS)

Jensen, Douglas R.

1990-01-01

During the months of June and July 1987, the Marine Stratocumulus Intensive Field Observation Experiment of First ISCCP Regional Experiment (FIRE) was conducted in the Southern California offshore area in the vicinity of San Nicolas Island (SNI). The Naval Ocean Systems Center (NOSC) airborne platform was utilized during FIRE to investigate the upwind low level horizontal variability of the marine boundary layer structure to determine the representativeness of SNI-based measurements to upwind open ocean conditions. The NOSC airborne meteorological platform made three flights during FIRE, two during clear sky conditions (19 and 23 July), and one during two stratus conditions (15 July). The boundary layer structure variations associated with the stratus clouds of 15 July 1987 are discussed. Profiles of air temperature (AT) and relative humidity (RH) taken 'at' and 'upwind' of SNI do show differences between the so-called open ocean conditions and those taken near the island. However, the observed difference cannot be uniquely identified to island effects, especially since the upwind fluctuations of AT and RH bound the SNI measurements. Total optical depths measures at SNI do not appear to be greatly affected by any surface based aerosol effects created by the island and could therefore realistically represent open ocean conditions. However, if one were to use the SNI aerosol measurements to predict ship to ship EO propagation conditions, significant errors could be introduced due to the increased number of surface aerosols observed near SNI which may not be, and were not, characteristic of open ocean conditions. Sea surface temperature measurements taken at the island will not, in general, represent those upwind open ocean conditions. Also, since CTT's varied appreciably along the upwind radials, measurements of CTT over the island may not be representative of actual open ocean CTT's.

The Seaplane Base Ivo Monti at S. Nicola Varano (fg): a Monument of Military Archeology, Between History and Protection

NASA Astrophysics Data System (ADS)

Mariano, F.; Saracco, M.; Petetta, L.

2017-05-01

Built in the years between 1915 and 1918, and located on the west bank of the "Varano" Lake, a bay running along the village of "Cagnano Varano", the "Ivo Monti" seaplane base was erected on a pre-existing medieval settlement which belonged to the Benedictine Monks from the town of "San Nicola Imbuti". During WWI, this seaplane base was turned, from a simple water airport, into a strategic military base for floatplanes. As a matter of fact, the large lagoon could be used as landing spot for the planes sent off to patrol the dalmatic coast, one of the historical regions of Croatia, then controlled by the Austrians. After WWI, after the seaplane became an outdated technology, the "Ivo Monti" base was progressively dismantled and then totally abandoned at the beginning of the 1950s. In 2014, considering the historical relevance of this site and the unmistakable architectural value of its elements, a research framework agreement was signed between the "DICEA" Department of Marche Polytechnic University and the city council of the town hosting the site, aimed at the development of shared scientific research projects revolving around the study, the valorisation, and the restoration of the military complex in question, which had been in a complete state of decay and neglect for too long. The still ongoing research project mentioned presents two main missions: the first is the historical reconstruction, the geometric mapping, and the robustness analysis of the ruins, by studying and faithfully representing the state of deterioration of the building materials and of the facilities; the second is the identification and the testing of potential architectural solutions for the conversion and the reuse of the site and of its facilities.

A crowd of pedestrian dynamics - The perspective of physics. Comment on "Human behaviours in evacuation crowd dynamics: From modelling to "big data" toward crisis management" by Nicola Bellomo et al.

Miguel, António F.

2016-09-01

Walking is the most basic form of transportation. A good understanding of pedestrian's dynamics is essential in meeting the mobility and accessibility needs of people by providing a safe and quick walking flow [1]. Advances in the dynamics of pedestrians in crowds are of great theoretical and practical interest, as they lead to new insights regarding the planning of pedestrian facilities, crowd management, or evacuation analysis. Nicola Bellomo's et al. article [2] is a very timely review of the related research on modelling approaches, computational simulations, decision-making and crisis response. It also includes an attempt to accurately define commonly used terms, as well as a critical analysis of crowd dynamics and safety problems. As noted by the authors, ;models and simulations offer a virtual representation of real dynamics; that are essential to understand and predict the ;behavioural dynamics of crowds; [2]. As a physicist, I would like to put forward some additional theoretical and practical contributions that could be interesting to explore, regarding the perspective of physics on about human crowd dynamics (panic as a specific form of behaviour excluded).

Factors influencing the practice of exclusive breastfeeding among Hong Kong Chinese women: a questionnaire survey.

PubMed

Ku, Ching-Man; Chow, Susan K Y

2010-09-01

The purpose of this article is to explore the relationships between breastfeeding knowledge, self-efficacy and demographic factors on breastfeeding patterns among Hong Kong Chinese primiparous women. Background.  There is substantial evidence showing that maternal education, social class, ethnic background and religion are related to the decision to initiate as well as continue breastfeeding. Nevertheless, not much is known about how the controllable factors are able to influence the practice with the Hong Kong Chinese population. A cross-sectional and correlational design. A convenience sample of 82 subjects who had normal vaginal delivery in the maternity unit of a regional hospital in Hong Kong was recruited. Linear regression analysis showed that subjects who lived with their mothers-in-law, had higher household income and higher gravida would be associated with a higher score in the Breastfeeding Self-Efficacy Scale. On the other hand, decisions to breastfeed made later in the pregnancy, father-in-law to 'pei-yue' (the Chinese practice whereby the new mother is expected to stay at home and to avoid all household chores and social activities during the first month after giving birth) and older in age would be associated with a lower score. Pei-yue is Chinese ritual of which the woman who has delivered should stay at home for one month and being taken care by others (this Chinese term is used throughout the article to indicate the time period described). Generalised estimating equations model revealed that women who had searched through the Internet for breastfeeding information, who had husbands to 'pei yue', lived in private housing, were married, had a domestic helper to 'pei yue' and who had attained higher education were more likely to practice exclusive breastfeeding.

First steps of bacteriophage SPP1 entry into Bacillus subtilis.

PubMed

Jakutytė, Lina; Lurz, Rudi; Baptista, Catarina; Carballido-Lopez, Rut; São-José, Carlos; Tavares, Paulo; Daugelavičius, Rimantas

2012-01-20

The mechanism of genome transfer from the virion to the host cytoplasm is critical to understand and control the beginning of viral infection. The initial steps of bacteriophage SPP1 infection of the Gram-positive bacterium Bacillus subtilis were monitored by following changes in permeability of the cytoplasmic membrane (CM). SPP1 leads to a distinctively faster CM depolarization than the one caused by podovirus ϕ29 or myovirus SP01 during B. subtilis infection. Depolarization requires interaction of SPP1 infective virion to its receptor protein YueB. The amplitude of depolarization depends on phage input and concentration of YueB at the cell surface. Sub-millimolar concentrations of Ca(2+) are necessary and sufficient for SPP1 reversible binding to the host envelope and thus to trigger depolarization while DNA delivery to the cytoplasm depends on millimolar concentrations of this divalent cation. A model describing the early events of bacteriophage SPP1 infection is presented. Copyright © 2011 Elsevier Inc. All rights reserved.

2017-09-29

The 2017 census of southern sea otters (Enhydra lutris nereis) was conducted between late April and early July along the mainland coast of central California and in April at San Nicolas Island in southern California. The 3-year average of combined counts from the mainland range and San Nicolas Island was 3,186, down by 86 sea otters from the previous year. This is the second year that the official index has exceeded 3,090, the Endangered Species Act delisting threshold identified in the U.S. Fish and Wildlife Service’s Southern Sea Otter Recovery Plan (the threshold would need to be exceeded for 3 consecutive years before delisting consideration). The 5-year average trend in abundance, including both the mainland range and San Nicolas Island populations, remains positive at 2.3 percent per year. Continuing lack of growth in the range peripheries likely explains the cessation of range expansion.

California sea otter (Enhydra lutris nereis) census results, Spring 2016

USGS Publications Warehouse

Tinker, M. Tim; Hatfield, Brian B.

2016-09-19

The 2016 census of southern sea otters Enhydra lutris nereis was conducted in May along the mainland coast of central California and in April at San Nicolas Island in southern California. The 3-year average of combined counts from the mainland range and San Nicolas Island was 3,272. This is the first year that the official index has exceeded 3,090, the Endangered Species Act delisting threshold suggested by the U.S. Fish and Wildlife Service (the threshold would need to be exceeded for 3 consecutive years before delisting consideration). The 5-year average trend in abundance, including both the mainland range and San Nicolas Island populations, is positive at 3.2 percent per year; however, regional trends vary, with localized declines at the southern and northern peripheries of the mainland range. The lack of population growth in the range peripheries over recent years likely explains the cessation of range expansion, with the range limits remaining almost unchanged from the previous 5 years.

Uta stansburiana and Elgaria multicarinata on the California Channel Islands: Natural dispersal or artificial introduction?

USGS Publications Warehouse

Mahoney, Meredith J.; Parks, Duncan S.M.; Fellers, Gary M.

2003-01-01

Uta stansburiana and Elgaria multicarinata occur on several California Channel Islands, and recent introduction of some populations has been suggested because of similarity in life-history traits and body size to mainland populations. We sequenced representatives of each species from mainland southern California and some of the islands on which they occur. For each species, cytochrome bsequence divergence is low across the narrow geographic area sampled. Analyses of 14 haplotypes of U. stansburiana suggest long-established residency on Santa Catalina and San Clemente Islands but more recent arrival on San Nicolas and Santa Cruz Islands. Analyses of eight haplotypes of E. multicarinata suggest these lizards may have been recently transported to San Nicolas Island.

It is little-known that physicist Albert Einstein strongly held the view that ``Racism is America's worst disease.'' Einstein was active in the fight against racism from the 1930's until his death in 1955. Included among his friends were a number of important Afro-American figures, including the educator W.E.B. DuBois, the actor and basso profundo singer Paul Robeson, and the soprano Marian Anderson. Based on the authors' work ``Einstein on Race and Racism.''

Golfingia (Nephasoma) nicolasi n. sp. is described. It is a long, slender species with a filiform introvert that is 6 to 7 times the length of the trunk. The species was often the numerically dominant taxon in samples collected from the San Nicolas Basin, California, and was also callected from several other basins off southern California. Analyses of several collections from the San Nicolas Basin show that the population was spatially patchy; temporal variation was also indicated but only one year was sampled adequately. Average population densities were highest at the base of the slopes descending into the basin from the highly productive Santa Rosa-Cortes Ridge and Tanner Bank. G. nicolasi appears to feed on the large amounts of organic detritus that accumulate from this source.

Coherent Seismic Arrivals in the P Wave Coda of the 2012 Mw 7.2 Sumatra Earthquake: Water Reverberations or an Early Aftershock?

NASA Astrophysics Data System (ADS)

Fan, Wenyuan; Shearer, Peter M.

2018-04-01

Teleseismic records of the 2012 Mw 7.2 Sumatra earthquake contain prominent phases in the P wave train, arriving about 50 to 100 s after the direct P arrival. Azimuthal variations in these arrivals, together with back-projection analysis, led Fan and Shearer (https://doi.org/10.1002/2016GL067785) to conclude that they originated from early aftershock(s), located ˜150 km northeast of the mainshock and landward of the trench. However, recently, Yue et al. (https://doi.org/10.1002/2017GL073254) argued that the anomalous arrivals are more likely water reverberations from the mainshock, based mostly on empirical Green's function analysis of a M6 earthquake near the mainshock and a water phase synthetic test. Here we present detailed back-projection and waveform analyses of three M6 earthquakes within 100 km of the Mw 7.2 earthquake, including the empirical Green's function event analyzed in Yue et al. (https://doi.org/10.1002/2017GL073254). In addition, we examine the waveforms of three M5.5 reverse-faulting earthquakes close to the inferred early aftershock location in Fan and Shearer (https://doi.org/10.1002/2016GL067785). These results suggest that the reverberatory character of the anomalous arrivals in the mainshock coda is consistent with water reverberations, but the origin of this energy is more likely an early aftershock rather than delayed and displaced water reverberations from the mainshock.

Observed cloud reflectivities and liquid water paths: An update

NASA Technical Reports Server (NTRS)

Coakley, James A., Jr.; Snider, Jack B.

1990-01-01

The FIRE microwave radiometer observations of liquid water path from San Nicolas Island and simultaneous NOAA AVHRR observations of cloud reflectivity were used to test a relationship between cloud liquid water path and cloud reflectivity that is often used in general circulation climate models (Stephens, 1978). The results of attempts to improve the data analysis which was described at the previous FIRE Science Team Workshop and elsewhere (Coakley and Snider, 1989) are reported. The improvements included the analysis of additional satellite passes over San Nicolas and sensitivity studies to estimate the effects on the observed reflectivities due to: (1) nonzero surface reflectivities beneath the clouds; (2) the anisotropy of the reflected radiances observed by the AVHRR; (3) small scale spatial structure in the liquid water path; and (4) adjustments to the calibration of AVHRR.

We examine the circular dichroism in the angular distribution of photoelectrons of triatomic model systems ionized by strong-field ionization. Following our recent work on this effect [Paul, Yue, and Gräfe, J. Mod. Opt. 64, 1104 (2017), 10.1080/09500340.2017.1299883], we demonstrate how the symmetry and electronic structure of the system is imprinted into the photoelectron momentum distribution. We use classical trajectories to reveal the origin of the threefolded pattern in the photoelectron momentum distribution, and show how an asymmetric nuclear configuration of the triatomic system effects the photoelectron spectra.

Jean Marian Purdy remembered - the hidden life of an IVF pioneer.

PubMed

Gosden, Roger

2018-06-01

Jean Purdy is almost forgotten as one of the British trio that introduced clinical IVF to the world. An unlikely pioneer, she qualified as a nurse but through indefatigable effort and unstinting loyalty to a programme that faced vitriolic opposition she became the clinical embryologist for the first IVF baby. In 1980, she helped to launch fertility services as the 'Technical Director' of Bourn Hall Clinic, near Cambridge. Although Robert Edwards and Patrick Steptoe generously credited her role in research and clinical care, a premature death in 1985 at age 39 robbed her of the reward of witnessing the blossoming of assisted reproductive technologies for patients around the world. This commentary seeks to recognize her contribution and bring her name to the attention of professionals in reproductive medicine and the patients they care for.

Folk Theorems on the Correspondence between State-Based and Event-Based Systems

NASA Astrophysics Data System (ADS)

Reniers, Michel A.; Willemse, Tim A. C.

Kripke Structures and Labelled Transition Systems are the two most prominent semantic models used in concurrency theory. Both models are commonly believed to be equi-expressive. One can find many ad-hoc embeddings of one of these models into the other. We build upon the seminal work of De Nicola and Vaandrager that firmly established the correspondence between stuttering equivalence in Kripke Structures and divergence-sensitive branching bisimulation in Labelled Transition Systems. We show that their embeddings can also be used for a range of other equivalences of interest, such as strong bisimilarity, simulation equivalence, and trace equivalence. Furthermore, we extend the results by De Nicola and Vaandrager by showing that there are additional translations that allow one to use minimisation techniques in one semantic domain to obtain minimal representatives in the other semantic domain for these equivalences.

Gender and the pre-1945 American Planetarium Community

NASA Astrophysics Data System (ADS)

Marche', J. D., II

1999-05-01

Before 1945, two American women, Maude V. Bennot (b. 1892) and Marian Lockwood (b. 1899), were appointed acting directors of Zeiss-equipped planetaria. Attainment of gender equity in the planetarium community, however, was a temporary measure later erased by the post-war cultural ideology of male superiority. Thereupon, women's roles were subordinated and devoid of the autonomy/authority they had exercised during years of national hardship and emergency. These case studies demonstrate the extension of concepts derived from gender studies in the history of American science to the realm of science popularization.

MapReduce is increasingly becoming a popular framework, and a potent programming model. The most popular open source implementation of MapReduce, Hadoop, is based on the Hadoop Distributed File System (HDFS). However, as HDFS is not POSIX compliant, it cannot be fully leveraged by applications running on a majority of existing HPC environments such as Teragrid and NERSC. These HPC environments typicallysupport globally shared file systems such as NFS and GPFS. On such resourceful HPC infrastructures, the use of Hadoop not only creates compatibility issues, but also affects overall performance due to the added overhead of the HDFS. This paper notmore » only presents a MapReduce implementation directly suitable for HPC environments, but also exposes the design choices for better performance gains in those settings. By leveraging inherent distributed file systems' functions, and abstracting them away from its MapReduce framework, MARIANE (MApReduce Implementation Adapted for HPC Environments) not only allows for the use of the model in an expanding number of HPCenvironments, but also allows for better performance in such settings. This paper shows the applicability and high performance of the MapReduce paradigm through MARIANE, an implementation designed for clustered and shared-disk file systems and as such not dedicated to a specific MapReduce solution. The paper identifies the components and trade-offs necessary for this model, and quantifies the performance gains exhibited by our approach in distributed environments over Apache Hadoop in a data intensive setting, on the Magellan testbed at the National Energy Research Scientific Computing Center (NERSC).« less

Then and Now: Women Respond to the Manhattan Project - an illustrated talk

NASA Astrophysics Data System (ADS)

Fermi, M. A., Olivia

2014-03-01

I am very much looking forward to visiting you, the family of physicists gathering for your annual APS conference. In different ways, my grandfather Enrico Fermi is a member of both our families. In this sense we are connected and share a common legacy, which I want to explore from the angle of two women inextricably involved with and affected by the Manhattan Project. One from the past and one alive now. These two women, despite a significant temporal and cultural gap share a remarkable number of traits and values. My talk will not offer a particular thesis or finding. Rather it will be about ways of seeing, including questioning unnoticed assumptions and belief systems. My grandmother Laura Fermi, modeled this for me as a youngster. She was at Enrico's side during the Manhattan Project years, yet in the dark about his work. What was it like to live in a climate of intellectually and patriotically charged enthusiasm, with an undercurrent of unspoken dread? Laura, just like most everyone else, discovered the true nature of the effort on the day the atomic bomb was dropped on Hiroshima. After the war and after Enrico's untimely death in 1954, in response to all she had experienced, Laura re-invented herself as an author and visionary, pioneering in both the environmental and handgun control movements. Marian Naranjo lives on the Santa Clara Pueblo near Los Alamos. Her ancestors dwelled on the Pajarito Plateau which encompasses the space where Los Alamos National Labs (LANL) is today. Her people, the Pueblo People have used the area's natural resources for ceremonial and survival for uncountable generations. They say, ``We are this place.'' What is it like to live on land one's families have safely occupied for thousands of years, with an undercurrent of dread at the prospect of toxic waste stream products from LANL? Like my grandmother did in her place and time, Marian builds community as an integral part of her environmental and social justice activism. She is

Uranium-Series Ages of Marine Terrace Corals from the Pacific Coast of North America and Implications for Last-Interglacial Sea Level History

USGS Publications Warehouse

Muhs, D.R.; Kennedy, G.L.; Rockwell, T.K.

1994-01-01

Few of the marine terraces along the Pacific coast of North America have been dated using uranium-series techniques. Ten terrace sequences from southern Oregon to southern Baja California Sur have yielded fossil corals in quantities suitable for U-series dating by alpha spectrometry. U-series-dated terraces representing the ???80,000 yr sea-level high stand are identified in five areas (Bandon, Oregon; Point Arena, San Nicolas Island, and Point Loma, California; and Punta Banda, Baja California); terraces representing the ???125,000 yr sea-level high stand are identified in eight areas (Cayucos, San Luis Obispo Bay, San Nicolas Island, San Clemente Island, and Point Loma, California; Punta Bands and Isla Guadalupe, Baja California; and Cabo Pulmo, Baja California Sur). On San Nicolas Island, Point Loma, and Punta Bands, both the ???80,000 and the ???125,000 yr terraces are dated. Terraces that may represent the ???105,000 sea-level high stand are rarely preserved and none has yielded corals for U-series dating. Similarity of coral ages from midlatitude, erosional marine terraces with coral ages from emergent, constructional reefs on tropical coastlines suggests a common forcing mechanism, namely glacioeustatically controlled fluctuations in sea level superimposed on steady tectonic uplift. The low marine terrace dated at ???125,000 yr on Isla Guadalupe, Baja California, presumed to be tectonically stable, supports evidence from other localities for a +6-m sea level at that time. Data from the Pacific Coast and a compilation of data from other coasts indicate that sea levels at ???80,000 and ???105,000 yr may have been closer to present sea level (within a few meters) than previous studies have suggested.

2016-09-01

The stay of Lémery in Montpellier as a companion-apothecary from 1668 until 1671 was attested, especially by his registration to the book of rolls. What he has done there is rather a matter of the oral tradition. But the atmosphere of rivalry and fuss between the followers of the Catholicism and those of the Protestantism was tangible through the trials, the rulings or the namings. Even unsaid things, for example in the books of chemistry published then, tell a lot on the atmosphere of the city during the three years of the stay of Lémery in Montpellier.

Birthing Ethics: What Mothers, Families, Childbirth Educators, Nurses, and Physicians Should Know About the Ethics of Childbirth

PubMed Central

Torres, Jennifer M; De Vries, Raymond G

2009-01-01

This article discusses current ethical issues associated with childbirth in the United States. It provides a review of moral problems and ethical choices made by parents and health-care professionals during the prenatal, intrapartum, and postpartum periods. Ethical issues are identified and framed through a “naturalized bioethics” approach, as recommended by Margaret Walker and her colleagues, Hilde Lindemann and Marian Verkerk. This approach critiques traditional bioethics and gives attention to everyday ethics and the social, economic, and political context within which ethical problems exist. This approach provides the reader with the tools needed to critically assess the way ethical problems are defined and resolved. PMID:19360141

Early outgassing of Mars supported by differential water solubility of iodine and xenon

NASA Technical Reports Server (NTRS)

Musselwhite, Donald S.; Drake, Michael J.; Swindle, Timothy D.

1991-01-01

The Martian atmosphere has a high X-129/Xe-132 ratio compared to the Martian mantle. As Xe-129 is the daughter product of the extinct nuclide I-129, a means of fractionating iodine from xenon early in Martian history appears necessary to account for the X-129/Xe-132 ratios of its known reservoirs. A model is presented here to account for the Marian xenon data which relies on the very different solubilities of xenon and iodine in water to fractionate them after outgassing. Atmospheric xenon is lost by impact erosion during heavy bombardment, followed by release of Xe-129 produced from I-129 decay in the crust.

The faculty of medicine of the university created in Pont-à-Mousson in the second part of the XVIth century, transferred to Nancy in 1768, was not in possession of a chair of chemistry, but, in the middle of the XVIIIth century, it was interested by the development of this science. In Nancy, the Royal College of medicine, created by King Stanislas in 1752, disposed of a professor of chemistry since 1756, and also of a demonstrator who was one of the apothecaries of the town. In Metz, a course of this science occurred between 1756 and 1769 with the apothecary Thyrion. In 1776, the physician Henry Michel du Tennetar and the apothecary Pierre-François Nicolas opened a private course of chemistry, immediately transformed into a chair of the faculty of medicine. This chair will be maintained until Révolution. The personality and work of Michel du Tennetar and Nicolas, the circumstances and conditions of the creation of the chair, the inheritance of Michel, and the appointment of the demonstrator, also an apothecary, are successively described.

Benzil was reduced stereospecifically to (S)-benzoin by Bacillus cereus strain Tim-r01. To isolate the gene responsible for asymmetric reduction, we constructed a library consisting of Escherichia coli clones that harbored plasmids expressing Bacillus cereus genes. The library was screened using the halo formation assay, and one clone showed benzil reduction to (S)-benzoin. Thus, this clone seemed to carry a plasmid encoding a Bacillus cereus benzil reductase. The deduced amino acid sequence had marked homologies to the Bacillus subtilis yueD protein (41% identity), the yeast open reading frame YIR036C protein (31%), and the mammalian sepiapterin reductases (28% to 30%), suggesting that benzil reductase is a novel short-chain de-hydrogenases/ reductase.

High MHC diversity maintained by balancing selection in an otherwise genetically monomorphic mammal

The San Nicolas Island fox (Urocyon littoralis dickeyi) is genetically the most monomorphic sexually reproducing animal population yet reported and has no variation in hypervariable genetic markers. Such low levels of variation imply lower resistance to pathogens, reduced fitness, and problems in distinguishing kin from non-kin. In vertebrates, the MHC contains genes that influence disease resistance and kin recognition and may be under intense balancing selection in some populations. Hence, genetic variation at the MHC might persist despite the extreme monomorphism shown by neutral markers. We examine variation of five loci within the MHC of San Nicolas Island foxes and find remarkably high levels of variation. Further, we show by simulation that genetic monomorphism at neutral loci and high MHC variation could arise only through an extreme population bottleneck of <10 individuals, ≈10–20 generations ago, accompanied by unprecedented selection coefficients of >0.5 on MHC loci. These results support the importance of balancing selection as a mechanism to maintain variation in natural populations and expose the difficulty of using neutral markers as surrogates for variation in fitness-related loci.

Structural and stratigraphic constraints on tsunamigenic rupture along the frontal Sunda megathrust from MegaTera bathymetric and seismic reflection data

The joint EOS/IPG/LIPI 2015 MegaTera expedition collected high-resolution seismic reflection profiles and bathymetric data across the Sunda trench, updip of the Mw7.7, 2010 Mentawai tsunami-earthquake rupture patch. These data reveal rapid lateral variations in both the stratigraphic level of the frontal Sunda megathrust and the vergence of frontal ramp faults. The stratigraphic depth of the megathrust at the deformation front correlates with ramp-thrust vergence and with changes in the basal friction angle inferred by critical-taper wedge theory. Where ramp thrusts verge uniformly seaward and have an average dip of 30°, the megathrust decollement resides atop a high-amplitude reflector that marks the inferred top of pelagic sediments. Where ramp thrusts are bi-vergent (similar throw on both landward- and seaward-vergent faults) and have an average dip of 42°, the decollement is higher, within the incoming clastic sequence, above a seismically transparent unit inferred to represent distal fan muds. Where ramp thrusts are uniformly landward vergent, the decollement sits directly on top of the oceanic crust that forms the bathymetrically prominent, subducting Investigator Ridge. The two, separate regions of large tsunamigenic ground-surface uplift during the 2010 tsunami earthquake that have been inferred from joint inversions of seismic, GPS, and tsunami data (e.g. Yue et al., 2014; Satake et al., 2013) correspond to the areas of frontal bi-vergence in the MegaTera data. We propose that enhanced surface uplift and tsunamigenesis during this event occurred when rupture propagated onto areas where the decollement sits directly above the basal muds of the incoming clastic sequence. Thus we hypothesize that frontal bi-vergence may mark areas of enhanced tsunami hazard posed by small magnitude, shallow megathrust ruptures that propagate to the trench.

Determining bacterial community structure in fecal samples through DNA sequencing is an important facet of intestinal health research. The impact of different commercially available DNA extraction kits upon bacterial community structures has received relatively little attention. The aim of this study was to analyze bacterial communities in volunteer and inflammatory bowel disease (IBD) patient fecal samples extracted using widely used DNA extraction kits in established gastrointestinal research laboratories. Fecal samples from two healthy volunteers (H3 and H4) and two relapsing IBD patients (I1 and I2) were investigated. DNA extraction was undertaken using MoBio Powersoil and MP Biomedicals FastDNA SPIN Kit for Soil DNA extraction kits. PCR amplification for pyrosequencing of bacterial 16S rRNA genes was performed in both laboratories on all samples. Hierarchical clustering of sequencing data was done using the Yue and Clayton similarity coefficient. DNA extracted using the FastDNA kit and the MoBio kit gave median DNA concentrations of 475 (interquartile range 228-561) and 22 (IQR 9-36) ng/µL respectively (p<0.0001). Hierarchical clustering of sequence data by Yue and Clayton coefficient revealed four clusters. Samples from individuals H3 and I2 clustered by patient; however, samples from patient I1 extracted with the MoBio kit clustered with samples from patient H4 rather than the other I1 samples. Linear modelling on relative abundance of common bacterial families revealed significant differences between kits; samples extracted with MoBio Powersoil showed significantly increased Bacteroidaceae, Ruminococcaceae and Porphyromonadaceae, and lower Enterobacteriaceae, Lachnospiraceae, Clostridiaceae, and Erysipelotrichaceae (p<0.05). This study demonstrates significant differences in DNA yield and bacterial DNA composition when comparing DNA extracted from the same fecal sample with different extraction kits. This highlights the importance of ensuring that samples

Small, rare and wide-ranging pelagic birds are difficult to locate and observe at sea; little is therefore known regarding individual movements and habitat affinities among many of the world's storm-petrels (Family Hydrobatidae). We re-located 57 of 70 radio-marked Ashy Storm-Petrels Oceanodroma homochroa captured at three colonies in the California Channel Islands: Scorpion Rocks (2004, 2005), Santa Barbara Island (2004) and Prince Island (2005). Between 23 July and 22 September 2004, and 5 July and 4 August 2005, we flew 29 telemetry surveys, covered more than 65 000 km2 (2004) and 43 000 km2 (2005) of open ocean from San Nicolas Island north to the Farallon Islands and obtained 215 locations from 57 storm-petrels at sea. In both years, radio-marked storm-petrels were aggregated over the continental slope from Point Conception to Point Buchon, within the western Santa Barbara Channel, and over the Santa Cruz Basin between Santa Cruz, San Nicolas and Santa Barbara islands. Individuals captured in the Channel Islands ranged more than 600 km and were located as far north as Gulf of the Farallones National Marine Sanctuary. This is the first study to use radiotelemetry to determine the at-sea distribution and movements for any storm-petrel species.

On the use of Multisensor and multitemporal data for monitoring risk degradation and looting in archaeological site

NASA Astrophysics Data System (ADS)

Masini, Nicola; Lasaponara, Rosa

2015-04-01

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

PubMed

Hodgson, M

1990-08-01

The objective of this article is to make a contribution to the evaluation of the accuracy and applicability of models for predicting the sound propagation in fitted rooms such as factories, classrooms, and offices. The models studied are 1:50 scale models; the method-of-image models of Jovicic, Lindqvist, Hodgson, Kurze, and of Lemire and Nicolas; the emprical formula of Friberg; and Ondet and Barbry's ray-tracing model. Sound propagation predictions by the analytic models are compared with the results of sound propagation measurements in a 1:50 scale model and in a warehouse, both containing various densities of approximately isotropically distributed, rectangular-parallelepipedic fittings. The results indicate that the models of Friberg and of Lemire and Nicolas are fundamentally incorrect. While more generally applicable versions exist, the versions of the models of Jovicic and Kurze studied here are found to be of limited applicability since they ignore vertical-wall reflections. The Hodgson and Lindqvist models appear to be accurate in certain limited cases. This preliminary study found the ray-tracing model of Ondet and Barbry to be the most accurate of all the cases studied. Furthermore, it has the necessary flexibility with respect to room geometry, surface-absorption distribution, and fitting distribution. It appears to be the model with the greatest applicability to fitted-room sound propagation prediction.

The Island Night Lizard is a federally threatened species endemic to the Channel Islands of California. Twelve microsatellite loci were developed for use in this species and screened in 197 individuals from across San Nicolas Island, California. The number of alleles per locus ranged from 6 to 21. Observed heterozygosities ranged from 0.520 to 0.843. These microsatellite loci will be used to investigate population structure, effective population size, and gene flow across the island, to inform protection and management of this species.

New high-precision thermal ionization mass-spectrometric (TIMS) U-series ages of solitary corals (Balanophyllia elegans) from several marine terrace localities along the California and southern Oregon coasts date to the ???80,000 yr BP high stand of sea, correlative with marine isotope substage 5a, late in the last interglacial complex. Ages of multiple corals from localities north of Point An??o Nuevo (central California) and San Nicolas Island (southern California) suggest that this high sea stand could have lasted at least 8000 yr, from ???84,000 to ???76,000 yr BP. These ages overlap with those from marine deposits on tectonically stable Bermuda and tectonically emergent Barbados. Higher-elevation terraces at two California localities, in the Palos Verdes Hills and on San Nicolas Island, have corals with ages that range mostly from ???121,000 to ???116,000 yr BP, correlative with marine isotope substage 5e. These ages are similar to those reported for other terraces in southern California but are younger than some ages reported from Hawaii, Barbados and the Bahamas. Marine terrace faunas are excellent proxies for nearshore marine paleotemperatures during past high sea stands. Terraces on the Palos Verdes Hills and San Nicolas Island dated to the ???120,000 yr BP high sea stand have dominantly zoogeographically "neutral" species in exposed coastal localities, indicating nearshore waters similar to those of today. In contrast, ???80,000 yr BP, exposed coastal localities typically have molluscan faunas characterized by numerous extralimital northern species and a lack of extralimital southern species. These fossil assemblages are indicative of nearshore water temperatures that were cooler than modern temperatures at ???80,000 yr BP. Waters at least as warm as today's at ???120,000 yr BP and cooler than present at ???80,000 yr BP are in excellent agreement with marine alkenone records and coastal vegetation records derived from pollen data, from both southern and

Operant psychology makes a splash--in marine mammal training (1955-1965).

PubMed

Gillaspy, James Arthur; Brinegar, Jennifer L; Bailey, Robert E

2014-01-01

Despite the wide spread use of operant conditioning within marine animal training, relatively little is known about this unique application of behavioral technology. This article explores the expansion of operant psychology to commercial marine animal training from 1955 to 1965, specifically at marine parks such as Marine Studios Florida, Marineland of the Pacific, Sea Life Park, and SeaWorld. The contributions of Keller and Marian Breland and their business Animal Behavior Enterprises (ABE) as well as other early practitioners of behavioral technology are reviewed. We also describe how operant technology was introduced and formalized into procedures that have become the cornerstone of marine animal training and entertainment. The rapid growth of the marine park industry during this time was closely linked to the spread of behavioral technology. The expansion of operant training methods within marine animal training is a unique success story of behavioral technology. © 2014 Wiley Periodicals, Inc.

Interconfigurational energies in transition-metal atoms using gradient-corrected density-functional theory

The rapid variation of charge and spin densities in atoms and molecules provides a severe test for local-density-functional theory and for the use of gradient corrections. In the study reported in this paper, we use the Langreth, Mehl, and Hu (LMH) functional and the generalized gradient approximation (GGA) of Perdew and Yue to calculate {ital s}-{ital d} transition energies, 4{ital s} ionization energies, and 3{ital d} ionization energies for the 3{ital d} transition-metal atoms. These calculations are compared with results from the local-density functional of Vosko, Wilk, and Nusair. By comparison with experimental energies, we find that the gradient functionalsmore » are only marginally more successful than the local-density approximation in calculating energy differences between states in transition-metal atoms. The GGA approximation is somewhat better than the LMH functional for most of the atoms studied, although there are several exceptions.« less

History of Astronomy in Moldova

NASA Astrophysics Data System (ADS)

Gaina, A.

The epoch of Stephen the Great (1457-1504) were marked in Moldova by a developement of astronomy in the connection with interests for navigation. Moldavian ships triped from Cetatea Alba (actualy Belgorod-Dniestrovskii, Odessa region, Ukraine) on Dniester gulf of the Black Sea to Genova and Venice. Other moldavian hospodars after the falling down of Moldova under the ottoman domination made attempts to develope astronomy as well as other natural sciences. Between them: Petru Rares (1527-1538, 1541-1546) and Demetrios Cantemir (1673-1723). The founder of the modern astronomy in Bessarabia is Nicolas N. Donitch (b. 1/13 september 1874 in Chisinau - d. 1956 or 1958 in Nice (?), France), member of the IAU since 1922, member of the russian, german, french and other astronomical societies, Honorary member of the Romanian Academy (1922-1948, reestablished in 1991). Donitch built the first private astronomical observatory in Starya Dubbosary (actualy Dubasarii-Vechi) in 1908. He dealt with solar and planet physics and astronomy, small bodies in solar system, meteorites researches, comet and solar eclipses observations, zodiacal light. After 1945 he worked in France. Now we have an astronomical observatory at the University and about 20 astronomers dealing with various branches of astronomy: from relativistic astrophysics and variable stars to solar system astronomy, celestial mechanics and atmospheric optics. We have a number of internationally recognized astronomers borne in Bessarabia or of Moldavian origin, worked in other countries, except Nicolas Donitch. Between them: V.A.Albitzky (1981-1951), A.N.Deutsch (1899-1968), N.Florea (1912-1941), V. Nadolschi, E.A.Grebenikov, M. Stavinschi and other.

'Cutting for the stone': the ancient art of lithotomy.

PubMed

Herr, Harry W

2008-05-01

Bladder stone was a common ailment plaguing mankind from antiquity to the 20th century. Largely forgotten today, lithotomy relieved the anguish of bladder stones and identified urology as a medical specialty nearly 2500 years ago. The historical literature pertaining to lithotomy was reviewed. Translated and original documents describing operative techniques and developments pertaining to the history of lithotomy were obtained through the internet and library sources. The ancient art of lithotomy was first recorded by the Greeks and evolved through five phases: the Celsian method, or 'lesser operation'; the Marian, or 'greater operation'; the lateral operation; suprapubic cystotomy, or 'high operation', and proctocystotomy. The practice of open lithotomy ceased to exist owing to better minimally invasive alternative methods and most notably by the virtual disappearance of bladder stones in modern man. The history of lithotomy is a fascinating story of how early surgeons forced by the culture and customs of the time dealt with common but devastating bladder stones. Out of their efforts, urology was born.

We measured total mercury (THg) concentrations in California sea lions (Zalophus californianus) and examined how concentrations varied with age class, colony, and sex. Because Hg exposure is primarily via diet, we used nitrogen (δ (15)N) and carbon (δ (13)C) stable isotopes to determine if intraspecific differences in THg concentrations could be explained by feeding ecology. Blood and hair were collected from 21 adult females and 57 juveniles from three colonies in central and southern California (San Nicolas, San Miguel, and Año Nuevo Islands). Total Hg concentrations ranged from 0.01 to 0.31 μg g(-1) wet weight (ww) in blood and 0.74 to 21.00 μg g(-1) dry weight (dw) in hair. Adult females had greater mean THg concentrations than juveniles in blood (0.15 vs. 0.03 μg(-1) ww) and hair (10.10 vs. 3.25 μg(-1) dw). Age class differences in THg concentrations did not appear to be driven by trophic level or habitat type because there were no differences in δ (15)N or δ (13)C values between adults and juveniles. Total Hg concentrations in adult females were 54 % (blood) and 24 % (hair) greater in females from San Miguel than females from San Nicolas Island, which may have been because sea lions from the two islands foraged in different areas. For juveniles, we detected some differences in THg concentrations with colony and sex, although these were likely due to sampling effects and not ecological differences. Overall, THg concentrations in California sea lions were within the range documented for other marine mammals and were generally below toxicity benchmarks for fish-eating wildlife.

Mutually exclusive splicing is an important means of increasing the protein repertoire, by which the Down's syndrome cell adhesion molecule (Dscam) gene potentially generates 38,016 different isoforms in Drosophila melanogaster. However, the regulatory mechanisms remain obscure due to the complexity of the Dscam exon cluster. Here, we reveal a molecular model for the regulation of the mutually exclusive splicing of the serpent pre-mRNA based on competition between upstream and downstream RNA pairings. Such dual RNA pairings confer fine tuning of the inclusion of alternative exons. Moreover, we demonstrate that the splicing outcome of alternative exons is mediated in relative pairing strength-correlated mode. Combined comparative genomics analysis and experimental evidence revealed similar bidirectional structural architectures in exon clusters 4 and 9 of the Dscam gene. Our findings provide a novel mechanistic framework for the regulation of mutually exclusive splicing and may offer potentially applicable insights into long-range RNA-RNA interactions in gene regulatory networks. © 2015 Yue et al.; Published by Cold Spring Harbor Laboratory Press for the RNA Society.

Comment on "A model for phosphate glass topology considering the modifying ion sub-network" [J. Chem. Phys. 140, 154501 (2014)

NASA Astrophysics Data System (ADS)

Sidebottom, David L.

2015-03-01

In a recent paper, Hermansen, Mauro, and Yue [J. Chem. Phys. 140, 154501 (2014)] applied the temperature-dependent constraint theory to model both the glass transition temperature, Tg, and fragility, m, of a series of binary alkali phosphate glasses of the form (R2O)x (P2 O 5) 1 - x , where R represents an alkali species. Key to their success seems to be the retention of linear constraints between the alkali ion (R+) and the non-bridging oxygens near Tg, which allows the model to mimic a supposed minimum for both Tg(x) and m(x) located near x = 0.2. However, the authors have overlooked several recent studies that clearly show there is no minimum in m(x). We argue that the retention of the alkali ion constraints at these temperatures is unjustified and question whether the model calculations can be revised to meet the actual experimental data. We also discuss alternative interpretations for the fragility based on two-state thermodynamics that can accurately account for its compositional dependence.

Autophagy in lurcher mice: indicted but yet to be acquitted for the death of Purkinje cells.

PubMed

Yue, Zhenyu

2010-05-01

A recent study published in the Journal of Neuroscience by Nishiyama et al., has revisited an autophagy-neurodegeneration model of lurcher (Lc) mice and promoted further discussion regarding the "autophagic cell death" hypothesis. While the study confirmed the previous report by Yue et al., that GluRD2Lc induces autophagy both in vitro and in vivo, it also suggests that GluRD2 (Lc)-mediated autophagy and cell death occur via pathways outside the nPIST-Beclin 1 pathway. For example, the study makes an interesting observation that GluRD2 (Lc)-induced degeneration is associated with energy crisis and an aberrant AMPK activity. The result provides insight into the downstream events induced by GluRD2 (Lc); however, it is not surprising considering that constitutive ion influx caused by the Lc mutation is expected to cause activation of multiple cellular pathways or responses. In conclusion, the authors state that "constitutive ion flux causes cell death with, but not by, autophagy." The conclusion appears consistent with the primary function of autophagy, from an evolutionary point of view, as a survival mechanism.

An applet for the Gabor similarity scaling of the differences between complex stimuli.

It is widely accepted that after the first cortical visual area, V1, a series of stages achieves a representation of complex shapes, such as faces and objects, so that they can be understood and recognized. A major challenge for the study of complex shape perception has been the lack of a principled basis for scaling of the physical differences between stimuli so that their similarity can be specified, unconfounded by early-stage differences. Without the specification of such similarities, it is difficult to make sound inferences about the contributions of later stages to neural activity or psychophysical performance. A Web-based app is described that is based on the Malsburg Gabor-jet model (Lades et al., 1993), which allows easy specification of the V1 similarity of pairs of stimuli, no matter how intricate. The model predicts the psycho physical discriminability of metrically varying faces and complex blobs almost perfectly (Yue, Biederman, Mangini, von der Malsburg, & Amir, 2012), and serves as the input stage of a large family of contemporary neurocomputational models of vision.

Preliminary results are given regarding black pepper powder decontamination using dielectric barrier discharge (DBD) plasma in atmospheric pressure. Three different DBD reactor constructions were investigated, both packaged and unpackaged material was treated. Due to potential, industrial applications, in addition to microbiological results, water activity, loss of mass and the properties of packaging material, regarding barrier properties were investigated. Argon based treatment of packed pepper with DBD reactor configuration is proposed and satisfactory results are presented for treatment time of 5 min or less.

Coakley, J. A., Jr.; Snider, J. B.

1989-01-01

Simultaneous observations of cloud liquid water content and cloud reflectivity are used to verify their parametric relationship in a manner consistent with simple parameterizations often used in general-circulation climate models. The column amount of cloud liquid water was measured with a microwave radiometer on San Nicolas Island as described by Hogg et al., (1983). Cloud reflectivity was obtained through spatial coherence analysis of AVHRR imagery data as per Coakley and Baldwin (1984) and Coakley and Beckner (1988). The dependence of the observed reflectivity on the observed liquid water is discussed, and this empirical relationship is compared with the parameterization proposed by Stephens (1978).

A model for the nonlocal transport and the associated distribution function deformation in magnetized laser-plasmas

Nicolaï, Ph.; Feugeas, J.-L.; Schurtz, G.

2006-06-01

We present a model of nonlocal transport for multidimensional radiation magneto hydrodynamic codes. In laser produced plasmas, it is now believed that the heat transfert can be strongly modified by the nonlocal nature of the electron conduction. Nevertheless other mechanisms as self generated magnetic fields may affect heat transport too. The model described in this work aims at extending the formula of G. Schurtz, Ph. Nicolaï and M. Busquet [1] to magnetized plasmas. A system of nonlocal equations is derived from kinetic equations with self-consistent electric and magnetic fields. These equations are analyzed and applied to a physical problem in order to demonstrate the main features of the model.

Pharmacy and Chemistry in the Eighteenth Century: What Lessons for the History of Science?

PubMed

Simon, Jonathan

2014-01-01

This essay questions the continuity of chemistry across the eighteenth century based on an analysis of its relationship to pharmacy in France. Comparing a text by Nicolas Lémery (1675) with one by Antoine Baumé (1773), the article argues for a key transformation in chemistry across this period. The elimination of the practical side of pharmacy (indications and dosages) from chemistry texts is symptomatic of a reorientation of chemistry toward more theoretical or philosophical concerns. The essay considers several possible explanations for this change in orientation, including developments within pharmacy, but in the end privileges an approach in terms of the changing publics for chemistry in eighteenth-century France.

Music, Mechanism, and the “Sonic Turn” in Physical Diagnosis

Pesic, Peter

2016-01-01

The sonic diagnostic techniques of percussion and mediate auscultation advocated by Leopold von Auenbrugger and R. T. H. Laennec developed within larger musical contexts of practice, notation, and epistemology. Earlier, François-Nicolas Marquet proposed a musical notation of pulse that connected felt pulsation with heard music. Though contemporary vitalists rejected Marquet's work, mechanists such as Albrecht von Haller included it into the larger discourse about the physiological manifestations of bodily fluids and fibers. Educated in that mechanistic physiology, Auenbrugger used musical vocabulary to present his work on thoracic percussion; Laennec's musical experience shaped his exploration of the new timbres involved in mediate auscultation.

Cosmic Rays in the "Urusvati" Institute from Archives of Nicolas Roerich Centre-Museum (Moscow)

2013-02-01

The history of cosmic ray study by means of ground-based methods in the 1930s contains some gaps. The press barely covered the study of cosmic rays at the "Urusvati» Himalayan Research Institute that functioned in the Indian Himalayas in 1928-1939. Archival materials of the "Urusvati" Institute now stored at the International Centre-Museum named after N.K. Roerich (Moscow), give evidence to the active participation of the Institute staff in the study of cosmic rays. By the initiative of A.H. Compton, in 1932 several expeditions on the studies of cosmic rays were organized in different parts of the world. One of these expeditions passed through the Himalayas in the region of the South-Eastern Ladakh. The report on this highland expedition which took place at the altitude of 19,500 feet above the sea level was published by J.M. Benade in the "Urusvati Journal" (was issued during 1931-1933). Cooperation between George Roerich, the Institute Director, and Prof. J.M. Benade in expedition to Ladakh has been documented.

[The chemists at the Paris Royal Academy of Sciences in the time of the Lémerys (1699-1743)].

Who were the chemists at the Paris Royal Academy of Sciences in the time of the Lémerys ? From the nomination of Nicolas Lémery, in 1699, until his death, in 1715, thirteen members of the Academy belonged to the section of Chemistry, and twenty-four until the death of Louis Lémery in 1743. In total, some thirty members made contributions dealing with chemistry, either famous like Réaumur and Buffon, or as obscure as Deschiens de Ressons, who opposed Louis Lémery. On the institutional level, most members of the chemical were promoted up to the coveted seats of senior members (pensionnaires) and several sat among the chief officiers (directeur, sous-directeur). The others were already too old when they entered or died too early : they merely stayed in the low rank of junior fellows (élève, then adjoint), or in the middle rank of associate (associé). A feature of their academic career was the porosity between the sections : a few members made it through the grades of both the section of chemistry and another among those of the “ physical sciences” (anatomy and botany). Many also had other positions, including in education : most of them had chairs or were deputy professors at the Jardin du Roi or the Collège royal, even more than at the Faculty of Medicine. On the sociological level, family recruitment was more important within the group of chemists than among the other members : in Nicolas Lémery’s time, nearly two thirds of them belonged to a sibling or dynasty. They usually had learnt chemistry at Faculty of Medicine or practiced it in their apothecary laboratory. The apothecaries were more numerous than ever : on the fourteen of them who belonged to the Royal Academy between 1666 and 1793, seven sat next to Nicolas Lémery. Nevertheless, a higher consideration was attached to the physicians, and apothecaries such as Lémery himself became medical doctors and started lineages of physicians. Lastly, on the scientific level, there was an important

English Medieval Churches, 'Festival Orientation' and William Wordsworth

NASA Astrophysics Data System (ADS)

Hoare, Peter G.; Ketel, Hans

2015-05-01

A church that is shown to be aligned with sunrise or sunset on the feast day of the saint to whom the building was dedicated is said to display 'festival orientation'. The earliest work to touch upon this practice in English dates from c. 1678. William Wordsworth gave impetus to the subject in two poems published in 1827; he also played a part in the design of St Mary's chapel (1823-4), Rydal, Cumbria in the English Lake District. The 14th-century St Catherine's chapel at Houghton St Giles, Norfolk, was constructed for the use of pilgrims on their way to nearby Walsingham. Careful measurement of the orientation and eastern horizon of these two buildings has shown that St Mary's is aligned with sunrise on the Marian festival of The Visitation (2 July), and St Catherine's is directed towards the rising Sun on the feast of St Catherine of Alexandria (25 November). It is only by taking into account the character of the horizon that meaningful tests for festival orientation may be carried out.

Aspects of Latino culture (e.g., machismo, marianism) can act as barriers to enrollment in HIV-prevention programs. To lift these barriers, a culturally appropriate meta-intervention was designed to increase intentions to enroll in HIV-prevention counseling by Latinos. Latino participants (N=41) were recruited from the community and randomly assigned to either an experimental or control meta-intervention condition that varied the introduction to a HIV-prevention counseling program. Following the meta-intervention, participants were issued an invitation to take part in HIV-prevention counseling. The outcome measure was the intention to enroll in a HIV-prevention counseling session. Findings indicated that enrollment intentions were higher in the experimental meta-intervention condition (96%) than in the control meta-intervention condition (53%). In addition, the effects of the meta-intervention were comparable across genders and participant ages. Findings suggest that the use of a culturally appropriate meta-intervention may be an effective strategy for increasing Latino enrollment in HIV-prevention programs. These promising findings warrant further investigation into the efficacy and effectiveness of this meta-intervention.

Peridotites in the Zabargad island, Red Sea, record different stages of lithospheric thinning and asthenospheric upwelling during rifting. Field mapping highlights a pervasive high-temperature NW-SE, subvertical foliation with lineations pluning 50°NW. This foliation is overprinted by a series of lower-temperature mylonitic zones with slightly oblique foliations and subhorizontal lineations, which record progressive strain localization under retrogressive conditions during the final exhumation of the peridotites (Nicolas and Boudier, JGR 1987). We performed a petrostructural study of ca. 50 samples collected by A. Nicolas and F. Boudier in the 80s from the different deformation facies. This study highlights: (1) a rather pervasive, but highly heterogeneous distribution of the LT deformation and (2) a feedback between deformation and fluid flow. The HT deformation is recorded in medium grained plagioclase- and spinel-peridotites by a homogeneous foliation and lineation marked by a shape-preferred orientation of plagioclase and olivine and a consistent CPO of all major-rock forming phases. The LT temperature deformation results in dynamic recrystallization of olivine leading to a marked grain size reduction by dynamic recrystallization of olivine, remobilization of orthopyroxene by dissolution-precipitation, and crystallization of amphibole. Increasing finite strain is recorded by the increase in the volume of the fine-grained material and of the amphibole proportion. The latter may attain in totally recrystallized cm-wide ultramylonite bands up to 30%. This together with the strong amphibole SPO and CPO corroborate fluid focusing and enhanced reaction rates into active shear zones. In the LT shear zones we also document: (1) changes in the olivine CPO, indicating changes in the dominant slip system and (2) unusual orthopyroxene CPO, which we interpret as due to oriented crystallization.

We measured total mercury (THg) concentrations in California sea lions (Zalophus californianus) and examined how concentrations varied with age class, colony, and sex. Because Hg exposure is primarily via diet, we used nitrogen (δ 15N) and carbon (δ 13C) stable isotopes to determine if intraspecific differences in THg concentrations could be explained by feeding ecology. Blood and hair were collected from 21 adult females and 57 juveniles from three colonies in central and southern California (San Nicolas, San Miguel, and Año Nuevo Islands). Total Hg concentrations ranged from 0.01 to 0.31 μg g−1 wet weight (ww) in blood and 0.74 to 21.00 μg g−1 dry weight (dw) in hair. Adult females had greater mean THg concentrations than juveniles in blood (0.15 vs. 0.03 μg−1 ww) and hair (10.10 vs. 3.25 μg−1 dw). Age class differences in THg concentrations did not appear to be driven by trophic level or habitat type because there were no differences in δ 15N or δ 13C values between adults and juveniles. Total Hg concentrations in adult females were 54 % (blood) and 24 % (hair) greater in females from San Miguel than females from San Nicolas Island, which may have been because sea lions from the two islands foraged in different areas. For juveniles, we detected some differences in THg concentrations with colony and sex, although these were likely due to sampling effects and not ecological differences. Overall, THg concentrations in California sea lions were within the range documented for other marine mammals and were generally below toxicity benchmarks for fish-eating wildlife.

Tracking the origins and diet of an endemic island canid (Urocyon littoralis) across 7300 years of human cultural and environmental change

Understanding how human activities have influenced the foraging ecology of wildlife is important as our planet faces ongoing and impending habitat and climatic change. We review the canine surrogacy approach (CSA)-a tool for comparing human, dog, and other canid diets in the past-and apply CSA to investigate possible ancient human resource provisioning in an endangered canid, the California Channel Islands fox (Urocyon littoralis). We conducted stable isotope analysis of bone collagen samples from ancient and modern island foxes (n = 214) and mainland gray foxes (Urocyon cinereoargenteus, n = 24). We compare these data to isotope values of ancient humans and dogs, and synthesize 29 Accelerator Mass Spectrometry (AMS) radiocarbon dates that fine-tune the chronology of island foxes. AMS dates confirm that island foxes likely arrived during the early Holocene (>7300 cal BP) on the northern islands in the archipelago and during the middle Holocene (>5500 cal BP) on the southern islands. We found no evidence that island foxes were consistently using anthropogenic resources (e.g., food obtained by scavenging around human habitation sites or direct provisioning by Native Americans), except for a few individuals on San Nicolas Island and possibly on San Clemente and Santa Rosa islands. Decreases in U. littoralis carbon and nitrogen isotope values between prehistoric times and the 19th century on San Nicolas Island suggest that changes in human land use from Native American hunter-gatherer occupations to historical ranching had a strong influence on fox diet. Island foxes exhibit considerable dietary variation through time and between islands and have adapted to a wide variety of climatic and cultural changes over the last 7300 years. This generalist foraging strategy suggests that endemic island foxes may be resilient to future changes in resource availability.

The influence of the geological setting on the morphogenetic evolution of the Tremiti Archipelago (Apulia, Southeastern Italy)

Andriani, G. F.; Walsh, N.; Pagliarulo, R.

2005-01-01

The Tremiti Archipelago (Southern Adriatic Sea), also called Insulae Diomedae from the name of the Greek hero who first landed there, is an area of high landscape and historical value. It is severely affected by significant geomorphologic processes dominated by mass movements along the coast that constitute the most important and unpredictable natural hazard for the population and cultural heritage. Coastal erosion is favoured by the peculiar geological and structural setting, seismic activity, weathering, development of karst processes, and wave action. The present paper reports on descriptive and qualitative evaluation of the factors controlling landslides and coastline changes based on medium-term in situ observation, detailed surface surveys at selected locations since 1995, and historic and bibliographic data. The Tremiti Archipelago is part of an active seismic area characterised by a shear zone separating two segments of the Adriatic microplate that have shown different behaviour and roll back rates in the subduction underneath the Apennines since middle Pleistocene. Although coastal morphology can be basically considered to be the result of wave action, the continual action of subaerial processes contributes effectively to the mechanism of shoreline degradation. Weathering mainly affects the marly calcisiltites and calcilutites of the Cretaccio Fm. and the friable and low cemented calcarenites and biomicrites of the San Nicola Fm. The cliffs are characterised by different types of failure such as lateral spreads, secondary topples, rock falls and slides. At the Isle of San Nicola, landslides are controlled by the contrast in competence, shear strength and stiffness between the Pliocene re-crystallised dolomitic calcarenites and calcisiltites and the Miocene marly calcilutites and calcisiltites. At the Isles of San Domino and Caprara rock falls are attributed to the undercutting of waves at the base of the cliffs.

Arsenic and Old Mustard: Chemical Problems of Old Arsenical and 'Mustard' Munitions (Joseph F. Bunnett and Marian Mikotajczyk, Eds.)

Garrett, Benjamin

1999-10-01

What do Knute Rockne, Notre Dame's famed football coach, and Lewisite, a chemical warfare agent dubbed "the dew of death", have in common? Both owe their discovery to Father Julius Arthur Nieuwland.1 Rockne's legacy lives on in the Fighting Irish and their tradition of excellence on the gridiron. Lewisite, together with other arsenical- and mustard-type chemical warfare agents, provide a legacy that lives on, too, but with less cheerful consequences. The book Arsenic and Old Mustard: Chemical Problems of Old Arsenical and 'Mustard' Munitions makes clear the challenges faced in dealing with those consequences. This book documents the proceedings of a workshop devoted to arsenical- and mustard-type chemical warfare agents and their associated munitions. The workshop, held in Poland in 1996, included nine lectures, eight posters, and three discussion groups; and the contents of all these are presented. Major support for the workshop came from the Scientific Affairs Division of NATO as part of on ongoing series of meetings, cooperative research projects, and related efforts dealing with problems leftover from the Cold War and, in the case of the arsenicals and mustards, from conflicts dating to World War I. These problems can be seen in contemporary accounts, including a January 1999 news report that the U.S. Department of Defense intends to survey Washington, DC, areas near both American University and the Catholic University of America (CUA), site of the original synthesis of Lewisite, for chemical warfare agents and other materials disposed at the end of World War I.2 The first nine chapters of the book present the workshop's lectures. Of these, readers interested in chemical weapon destruction might find especially useful the first chapter, in which Ron Mansley of the Organisation for the Prohibition of Chemical Weapons presents a scholarly overview covering historical aspects of the arsenicals and mustards; their production and use; prospective destruction technologies; and international obligations attendant to the Chemical Weapons Convention, which entered into force in 1997. Hermann Martens's presentation of German arsenical and mustard munitions and of technical approaches to their destruction is similarly detailed, thorough, and engaging. W. R. Cullen's chapter "Arsenic in the Environment" and Shigeru Maeda's chapter "Biotransformation of Arsenic in Freshwater Organisms" help place the problems associated with the arsenicals in their environmental context and, hence, should appeal to a large audiencenot merely those specialists dealing with chemical weapon destruction. The reports of the three discussion groupsYperite,3 Arsenicals, and Recovered Munitionsprovide useful summaries of current knowledge and needs for additional research. The Arsenicals report observes that "destruction of arsenical agents appears to have received little attention." This situation may change if searches in Washington, DC, should uncover caches of old arsenicals at CUA and, especially, when the governments of the People's Republic of China and Japan agree on funding for destruction of the chemical munitions Japan caused to be abandoned on what is now the territory of the PRC. A conservative estimate is that there are 2,000,000 of these abandoned munitions, most of them being arsenicals and mustards.4 Notes and References 1. Nieuwland (1878-1936) hired Rockne in 1914 as a chemistry instructor. According to Father Nieuwland, Rockne owed much of his prowess as one of the greatest coaches of all time to his training in chemistry, which taught him the method of reasoning (Ind. Eng. Chem. New Ed., April 20, 1931). W. Lee Lewis, Lewisite's eponym, credits Nieuwland's unpublished dissertation as the source for his 1918 synthesis (Lewis, W. L.; Perkins, G. A. The beta-Chlorovinyl Chloroarsines; Ind. Eng. Chem. 1923, 15, 290-295). Lewisite itself is actually the group of mono-, di-, and tri-substituted 2-chloroethenyl derivatives of arsenic(III) chloride. 2. Vogel, S.

Under the mirror of the sleeping water: Poussin's Narcissus.

Tutter, Adele

2014-12-01

Examined in conjunction with a close reading of Ovid's Metamorphoses, Nicolas Poussin's four paintings on the preoccupying theme of Narcissus and Echo reflect a developing aesthetic interpretation of its textual source. Poussin's reflective vision supports a radical reappraisal of the enigmatic myth at the heart of psychoanalytic theory and practice, in which Narcissus is construed as a far more object-related figure that seeks the formative, affirmative mirroring of the other. This in turn encourages a more versatile conceptualization of narcissistic disturbance, in which an etiologically heterogenous constellation of issues stems from a variety of disturbances in the myriad dynamic and developmental aspects of mirroring and attunement: the narcissisms.

The blossoms of loss: Ovid's floral metamorphoses and Poussin's realm of flora.

PubMed

Tutter, Adele

2014-07-01

Alluring and fertile, the flower connotes a locus of desire. The floral metamorphic myths narrated in Ovid's Metamorphoses (AD 8a) thematize the price of desire--the shame, grief, and rage of rejection and rivalrous defeat--and symbolize the generative transformation that frustrated desire and competitive loss can promote. In the deceptively beautiful painting Realm of Flora of 1631, Nicolas Poussin enlists these myths as allegories of his own great creative leap, an aesthetic metamorphosis that followed shattering defeats. Extending the association between creativity and object loss to competitive loss, Poussin holds a mirror to our powerful drive to prevail and create anew from the ashes of loss. © 2014 The Psychoanalytic Quarterly, Inc.

Acute pancreatitis is one of most common causes of consultation due to abdominal pain in medical emergency units and it requires hospital admission. Although the majority of cases are mild and patients tend to recover quickly, a small percentage of cases is severe, with mortality in the region of 5-10%. This historical review considers how our understanding of this disease has changed since it was first described in 1579 thanks to the contributions of renowned experts such as Nicolaes Tulp, Reginald Fitz, Nicholas Senn and many others who, through their expertise and dedication, have improved the survival of patients with this disease.

New Web technologies provide new opportunities but also include new risks. In an article in the May 2003 edition of Harvard Business Review, Editor Nicolas G. Carr said, "executives need to shift their attention from IT opportunities to IT risks-from offense to defense." That's probably a bit extreme. A better approach is to look at IT the same way you look at any business proposition. Every decision should be an informed decision. You should weigh the opportunities against the risks in order to select the best option. Then, once you have made your decision, take the necessary steps to minimize and prepare for the risks. This includes preparing for whatever disaster may come your way.

Ph.-N. Pia is known as a philanathropist. In 1770, this apothecary is elected at the board of the city of Paris. Then, he wishes to create a first-aid service to rescue drowned people. In wooden boxes, he gathers together the drugs and devices used at that time, as a fumigating machine to inject tobacco smoke into the intestine, bottles of spirit of camphor, ammonia, a long shirt of wool, wood canulas and flexible pipes made of thin sheep leather. In each of the fiveteen guard houses standing along the river, are deposited a box and a stretcher. As far as Pia is at the head of the military police, he is especially innovating when he decids to train the guards to apply the drugs and the resuscitation processes. With such a regulated way of functioning associated to medical education and granting of awards, within fiveteen years hundreds of people are rescued and resuscitated. Yearly, he publishes the results obtained in Paris and in several places in France, with comments on the situation in the Netherlands, Germany and Britain. In 1780, the king nominates him in the royal order of Saint-Michel. The Révolution supresses the Etablissement en faveur des noyés, and Pia died in 1799 as completely forgotten. In Paris, the first-aid services come back to their former efficiency around 1835, when Marc proposes a special medical training to the fire-men and the military police to form first-aid groups. In this field, the pionneering work of Pia is still of great value and can abe kept in mind as a worldwide reference.

In a recent paper, Hermansen, Mauro, and Yue [J. Chem. Phys. 140, 154501 (2014)] applied the temperature-dependent constraint theory to model both the glass transition temperature, T{sub g}, and fragility, m, of a series of binary alkali phosphate glasses of the form (R{sub 2}O){sub x}(P{sub 2}O{sub 5}){sub 1−x}, where R represents an alkali species. Key to their success seems to be the retention of linear constraints between the alkali ion (R{sup +}) and the non-bridging oxygens near T{sub g}, which allows the model to mimic a supposed minimum for both T{sub g}(x) and m(x) located near x = 0.2. However,more » the authors have overlooked several recent studies that clearly show there is no minimum in m(x). We argue that the retention of the alkali ion constraints at these temperatures is unjustified and question whether the model calculations can be revised to meet the actual experimental data. We also discuss alternative interpretations for the fragility based on two-state thermodynamics that can accurately account for its compositional dependence.« less

Complex networks provide us a new view for investigation of immune systems. We collect data through STRING database and present a network description with cooperation network model. The cytokine-protein network model we consider is constituted by two kinds of nodes, one is immune cytokine types which can be regarded as collaboration acts, the other one is protein type which can be regarded as collaboration actors. From act degree distribution that can be well described by typical SPL (shifted power law) functions [1], we find that HRAS, TNFRSF13C, S100A8, S100A1, MAPK8, S100A7, LIF, CCL4, CXCL13 are highly collaborated with other proteins. It reveals that these mediators are important in cytokine-protein network to regulate immune activity. Dyad in the collaboration networks can be defined as two proteins and they appear in one cytokine collaboration relationship. The dyad act degree distribution can also be well described by typical SPL functions.

Abstract: SAPS simulation with GITM/UCLA-RCM coupled model Author: Yang Lu, Yue Deng, Jiapeng Guo, Donghe Zhang, Chih-Ping Wang, Cheng Sheng Ion velocity in the Sub Aurora region observed by Satellites in storm time often shows a significant westward component. The high speed westward stream is distinguished with convection pattern. These kind of events are called Sub Aurora Polarization Stream (SAPS). In March 17th 2013 storm, DMSP F18 satellite observed several SAPS cases when crossing Sub Aurora region. In this study, Global Ionosphere Thermosphere Model (GITM) has been coupled to UCLA-RCM model to simulate the impact of SAPS during March 2013 event on the ionosphere/thermosphere. The particle precipitation and electric field from RCM has been used to drive GITM. The conductance calculated from GITM has feedback to RCM to make the coupling to be self-consistent. The comparison of GITM simulations with different SAPS specifications will be conducted. The neutral wind from simulation will be compared with GOCE satellite. The comparison between runs with SAPS and without SAPS will separate the effect of SAPS from others and illustrate the impact on the TIDS/TADS propagating to both poleward and equatorward directions.

Approximate Equation of State for Overdriven and Reflected Detonation Products

Approximate Equation of State for Overdriven and Reflected Detonation Products Zhi-Yue Liu and Shigeru Itoh Shock Wave and Condensed Matter Research Center, Kumamoto University, 2-39-1 Kurokami, Kumamoto, 860-8555, Japan ABSTRACT There are several types of equations of state (EOS) to describe the isentropic expansion behavior of the detonation products after the explosive is exploded. Of which, Jones-Wilkins-Lee (or JWL) equation and polytropic gas (or gamma-law) equation are most popularly employed owing to either the completely experimental calibration or simple form in expression. However, both equations fail to correctly describe the behavior of detonation products above the Chapman-Jouguet (C-J) state. For this reason, a new form of equation of state is proposed for overcoming this deficiency. The new equation of state is simply a linear combination of JWL and gamma-law equations. The coefficient appeared in the EOS can be obtained by fitting to the data from the overdriven detonation experiments. Results show that this form of EOS not only gives the satisfactory description to the variation of the detonation products in overdriven or reflected state also can simply be incorporated into the hydrodynamic computer codes.

Earlier, François-Nicolas Marquet proposed a musical notation of pulse that connected felt pulsation with heard music. Though contemporary vitalists rejected Marquet's work, mechanists such as Albrecht von Haller included it into the larger discourse about the physiological manifestations of bodily fluids and fibers. Educated in that mechanistic physiology, Auenbrugger used musical vocabulary to present his work on thoracic percussion; Laennec's musical experience shaped his exploration of the new timbres involved in mediate auscultation. © The Author 2015.

A Logical Process Calculus

NASA Technical Reports Server (NTRS)

Cleaveland, Rance; Luettgen, Gerald; Bushnell, Dennis M. (Technical Monitor)

2002-01-01

This paper presents the Logical Process Calculus (LPC), a formalism that supports heterogeneous system specifications containing both operational and declarative subspecifications. Syntactically, LPC extends Milner's Calculus of Communicating Systems with operators from the alternation-free linear-time mu-calculus (LT(mu)). Semantically, LPC is equipped with a behavioral preorder that generalizes Hennessy's and DeNicola's must-testing preorder as well as LT(mu's) satisfaction relation, while being compositional for all LPC operators. From a technical point of view, the new calculus is distinguished by the inclusion of: (1) both minimal and maximal fixed-point operators and (2) an unimple-mentability predicate on process terms, which tags inconsistent specifications. The utility of LPC is demonstrated by means of an example highlighting the benefits of heterogeneous system specification.

The Making of the Fathers of Astronomy Exhibit

Graney, C. M.

2010-10-01

The International Year of Astronomy 2009 stretched a few days into 2010 here in Louisville, Kentucky - the Fathers of Astronomy exhibit at the Frazier International History Museum did not close until 3 January 2010. Fathers of Astronomy, which was open for five months, told the story of Galileo through authentic original editions of three books - the 1493 Nuremberg Chronicle, Nicolas Copernicus's 1543 On the Revolutions of Heavenly Spheres, and Galileo Galilei's 1632 Dialogue Concerning the two Chief World Systems. The success of "Fathers" resulted from three very different partners coming together and combining resources to produce a history-themed IYA2009 programme of the highest quality at minimal cost. Lessons learned from the exhibit may be of value to people interested in communicating astronomy to the public.

The Surprising History of Claims for Life on the Sun

NASA Astrophysics Data System (ADS)

Crowe, Michael J.

2011-11-01

Because astronomers are now convinced that it is impossible for life, especially intelligent life, to exist on the Sun and stars, it might be assumed that astronomers have always held this view. This paper shows that throughout most of the history of astronomy, some intellectuals, including a number of well-known astronomers, have advocated the existence of intelligent life on our Sun and thereby on stars. Among the more prominent figures discussed are Nicolas of Cusa, Giordano Bruno, William Whiston, Johann Bode, Roger Boscovich, William Herschel, Auguste Comte, Carl Gauss, Thomas Dick, John Herschel, and François Arago. One point in preparing this paper is to show differences between the astronomy of the past and that of the present.

2010-05-01

Since Bandar Abbas city is located in a strategic commercial, recreational, fishery, political and military region, its coastline has been employed for different application during last three decades, especially construction of Marian facilities. Therefore, conducting of research projects has become important for management decision making and development of coastal zone of the city. This fact becomes more realistic when the coast is classified based on different views and each part of the coast is investigated as a cell or sub cell due to its different behavior. In this, first, different methods for classification of coasts have been reviewed. Then, emphasizing on hydrodynamic and morphological classification, the slope, morphological aspects, kind of coastline and the gradation of its materials, as well as the slope of coastline have been determined. Moreover, the characteristics of wind waves in the region have been investigated using the SW module of MIKE21 software. On the other hands, the beach state has been determined using Masselink & Short, Masselink & Hegge, and Short & Hesp methods and employing RTR and Ω parameters. Finally, the regions of accretion and erosion in this coast line have been investigated using aerial and satellite images captured during last decades.

Thermodynamic scaling in ionically conducting glasses and melts

NASA Astrophysics Data System (ADS)

Habasaki, Junko

2013-02-01

Molecular dynamics simulations have been performed to learn temperature, composition, pressure dependencies of the diffusivity and structures in the system having ion channels and network formers. Validity of the thermodynamic scaling in the lithium silicate glasses and melts is shown, where the scaling concept is extended with an aid of a percolation aspect of the ion channels. All diffusion coefficients of ions of different compositions, temperatures, pressures are successfully represented by a single master curve as a function of system volumes, temperatures and volume fraction of M2O part. It enables us to predict the diffusivity in different conditions. Furthermore, it suggests an applicability of scaling concept for the sub-structures in more complex systems. Nearby points on the master curve have the comparable MSD as well as self-part of the van Hove functions. Similarity is observed from an early term region. This observation is consistent to our previous claims [K. L. Ngai, J. Habasaki, D. Prevosto, S. Capaccioli, Marian Paluch, J. Chem. Phys. 137, 034511 (2012)] that the thermodynamic scaling of α-Relaxation time stems from the Johari-Goldstein β-relaxation or the primitive relaxation of the coupling model.

Heat flux variations over sea ice observed at the coastal area of the Sejong Station, Antarctica

Park, Sang-Jong; Choi, Tae-Jin; Kim, Seong-Joong

2013-08-01

This study presents variations of sensible heat flux and latent heat flux over sea ice observed in 2011 from the 10-m flux tower located at the coast of the Sejong Station on King George Island, Antarctica. A period from July to September was selected as a sea ice period based on daily record of sea state and hourly photos looking at the Marian Cove in front of the Sejong Station. For the sea ice period, mean sensible heat flux is about -11 Wm-2, latent heat flux is about +2 W m-2, net radiation is -12 W m-2, and residual energy is -3 W m-2 with clear diurnal variations. Estimated mean values of surface exchange coefficients for momentum, heat and moisture are 5.15 × 10-3, 1.19 × 10-3, and 1.87 × 10-3, respectively. The observed exchange coefficients of heat shows clear diurnal variations while those of momentum and moisture do not show diurnal variation. The parameterized exchange coefficients of heat and moisture produces heat fluxes which compare well with the observed diurnal variations of heat fluxes.

Validation of satellite retrievals of cloud microsphysics and liquid water path using observations from FIRE

Rossow, W.; White, A.; Han, Q.; Welch, R.; Chou, J.

1995-01-01

Cloud effective radii (r(sub e)) and cloud liquid water path (LWP) are derived from ISCCP spatially sampled satellite data and validated with ground-based pyranometer and microwave radiometer measurements taken on San Nicolas Island during the 1987 FIRE IFO. Values of r(sub e) derived from the ISCCP data are also compared to values retrieved by a hybrid method that uses the combination of LWP derived from microwave measurement and optical thickness derived from GOES data. The results show that there is significant variability in cloud properties over a 100 km x 80 km area and that the values at San Nicolas Island are not necessarily representative of the surrounding cloud field. On the other hand, even though there were large spatial variations in optical depth, the r(sub e) values remained relatively constant (with sigma less than or equal to 2-3 microns in most cases) in the marine stratocumulus. Furthermore, values of r(sub e) derived from the upper portion of the cloud generally are representative of the entire stratiform cloud. When LWP values are less than 100 g m(exp -2), then LWP values derived from ISCCP data agree well with those values estimated from ground-based microwave measurements. In most cases LWP differences were less than 20 g m(exp -2). However, when LWP values become large (e.g., greater than or equal to 200 g m(exp -2)), then relative differences may be as large as 50%- 100%. There are two reasons for this discrepancy in the large LWP clouds: (1) larger vertical inhomogeneities in precipitating clouds and (2) sampling errors on days of high spatial variability of cloud optical thicknesses. Variations of r(sub e) in stratiform clouds may indicate drizzle: clouds with droplet sizes larger than 15 microns appear to be associated with drizzling, while those less than 10 microns are indicative of nonprecipitating clouds. Differences in r(sub e) values between the GOES and ISCCP datasets are found to be 0.16 +/- 0.98 micron.

High magnetic susceptibility granodiorite as a source of surface magnetic anomalies in the King George Island, Antarctica

Kon, S.; Nakamura, N.; Funaki, M.; Sakanaka, S.

2012-12-01

Change in plate motion produces convergence of the two oceanic lithospheres and the formation of volcanic island arcs above the subducted older and thicker plate. The association of calc-alkaline diorites to tonalites and granodiorites (ACG) is typical plutonic rocks of the volcanic arcs. In the many island arcs that surround the Pacific Ocean, ACG generally forms shallow level plutons and is closely associated with volcanic rocks. The Japan Arc setting had occurred the emplacement of the highly magnetic granitoid along the fore-arc basin before back-arc spreading at middle Miocene, showing a linear positive magnetic anomaly. Similar magnetic anomalies have also been exhibited along the Circum-Pacific Belt. Along East Antarctica, it is well known that the South Shetland Islands have been formed by back-arc spreading related to the subduction along the South Shetland trench during the late Cretaceous and middle Miocene. Moreover, geology in the South Shetland Islands consists of lava flows with subordinate pyroclastic deposits, intrusive dykes-sills, granitic plutons, displaying a typical subduction-related calc-alkaline volcanic association. However, there is little report on the presence of fore-arc granitoid. Here we report the distribution and structure of the granitic plutons around Marian Cove in the King George Island, South Shetland, East Antarctica by surface geological survey and magnetic anisotropic studies. Then we compare the distribution of granitic plutons with surface magnetic anomalies through our ship-borne and foot-borne magnetic surveys. The granitic plutons are distributed only shallow around the Marian cove in the King George Island, and the plutons had been intruded in the Sejong formation with pyroclastic deposits and basaltic/rhyoritic lavas, suggesting the post back-arc spreading. We sampled 8 plutons, 12 basaltic lavas and 6 andestic dykes, all located within four kilometer radius from the Korean Antarctic research station (King Sejong

This study deals with paracetamol degradation in water using a non-thermal plasma (NTP) created by a dielectric barrier discharge (DBD). The effects of the NTP operating conditions on the degradation were studied, showing that the treatment efficiency of the process was highly dependent on the electrical parameters and working gas composition in the reactor containing the aqueous solution. A conversion rate higher than 99% was reached with an energy yield of 12 g/kWh. High resolution mass spectrometry (HRMS) measurements showed that the main species produced in water during the process were nitrogen compounds, carboxylic acids and aromatic compounds.

Cracking induction in health libraries: is there a right way?

PubMed

Forgham-Healey, Nicola

2017-06-01

In most instances, inductions are the first time that users will be introduced to health library services. The time available in which to deliver library orientation sessions within a broader, Trust induction programme is often limited, and this can present challenges for health librarians. Inductions are a great marketing tool, and it is important that induction sessions make the right impact. Within a brief window of opportunity, the health librarian must impart key information to the inductees whilst ensuring the session is relevant and memorable. In this article, guest writer Nicola Healey, Library Manager of North Somerset Healthcare Library, discusses the range of approaches she and her colleagues have explored in delivering library inductions, explaining what worked, what did not and what areas still remain for development.

We present an empirical investigation on the neuroendocrine system and suggest describe it by a bipartite graph. In the net the cells can be regarded as collaboration acts and the mediators can be regarded as collaboration actors. The act degree stands for the number of the cells that secrete a single mediator. Among them bFGF (the basic fibroblast growth factor) has the largest node act degree. It is the most important mitogenic cytokine, followed by TGF-beta, IL-6, IL1-beta, VEGF, IGF-1and so on. They are critical in neuroendocrine system to maintain bodily healthiness, emotional stabilization and endocrine harmony. The act degree distribution shows a shifted power law (SPL) function forms [1]. The average act degree of neuroendocrine network is h=3.01, It means that each mediator is secreted by three cells on average. The similarity, which stands for the average probability of secreting the same mediators by all neuroendocrine cells, is observed as s=0.14. Our results may be used in the research of the medical treatment of neuroendocrine diseases.

Discrete-State Stochastic Models of Calcium-Regulated Calcium Influx and Subspace Dynamics Are Not Well-Approximated by ODEs That Neglect Concentration Fluctuations

PubMed Central

Weinberg, Seth H.; Smith, Gregory D.

2012-01-01

Cardiac myocyte calcium signaling is often modeled using deterministic ordinary differential equations (ODEs) and mass-action kinetics. However, spatially restricted “domains” associated with calcium influx are small enough (e.g., 10−17 liters) that local signaling may involve 1–100 calcium ions. Is it appropriate to model the dynamics of subspace calcium using deterministic ODEs or, alternatively, do we require stochastic descriptions that account for the fundamentally discrete nature of these local calcium signals? To address this question, we constructed a minimal Markov model of a calcium-regulated calcium channel and associated subspace. We compared the expected value of fluctuating subspace calcium concentration (a result that accounts for the small subspace volume) with the corresponding deterministic model (an approximation that assumes large system size). When subspace calcium did not regulate calcium influx, the deterministic and stochastic descriptions agreed. However, when calcium binding altered channel activity in the model, the continuous deterministic description often deviated significantly from the discrete stochastic model, unless the subspace volume is unrealistically large and/or the kinetics of the calcium binding are sufficiently fast. This principle was also demonstrated using a physiologically realistic model of calmodulin regulation of L-type calcium channels introduced by Yue and coworkers. PMID:23509597

Generation of synthetic flood hydrographs by hydrological donors (SHYDONHY method)

NASA Astrophysics Data System (ADS)

Paquet, Emmanuel

2017-04-01

For the design of hydraulic infrastructures like dams, a design hydrograph is required in most of the cases. Some of its features (e.g. peak value, duration, volume) corresponding to a given return period are computed thanks to a wide range of methods: historical records, mono or multivariate statistical analysis, stochastic simulation, etc. Then various methods have been proposed to construct design hydrographs having such characteristics, ranging from traditional unit-hydrograph to statistical methods (Yue et al., 2002). A new method to build design hydrographs (or more generally synthetic hydrographs) is introduced here, named SHYDONHY, French acronym for "Synthèse d'HYdrogrammes par DONneurs HYdrologiques". It is based on an extensive database of 100 000 flood hydrographs recorded at hourly time-step on 1300 gauging stations in France and Switzerland, covering a wide range of catchment size and climatology. For each station, an average of two hydrographs per year of record has been selected by a peak-over-threshold (POT) method with independence criteria (Lang et al., 1999). This sampling ensures that only hydrographs of intense floods are gathered in the dataset. For a given catchment, where few or no hydrograph is available at the outlet, a sub-set of 10 "donor stations" is selected within the complete dataset, considering several criteria: proximity, size, mean annual values and regimes for both total runoff and POT-selected floods. This sub-set of stations (and their corresponding flood hydrographs) will allow to: • Estimate a characteristic duration of flood hydrographs (e.g. duration for which the discharge is above 50% of the peak value). • For a given duration (e.g. one day), estimate the average peak-to- volume ratio of floods. • For a given duration and peak-to-volume ratio, generation of a synthetic reference hydrograph by combining appropriate hydrographs of the sub-set. • For a given daily discharge sequence, being observed or generated

DC diaphragm discharge generated in a batch reactor was used to decompose two selected model alkaloids, caffeine and quinine in concentrations ranging from 10 to 50 ppm or 5 to 15 ppm, respectively. UV-vis spectrometry was utilized in evaluation of H2O2 production during the process as well as degradation of caffeine. Fluorescence spectrometry was used for quantification of quinine. High rates of decomposition were reached in both cases in the anode part of the reactor. On the other hand, up to four times lower decomposition was observed in the cathode part. Total removal efficiency gained up to 300 mg/kWh for caffeine and 210 mg/kWh for quinine.

Porphyry of Russian Empires in Paris A. G. Bulakh (St Petersburg State University, Russia) So called "Schokhan porphyry" from Lake Onega, Russia, belongs surely to stones of World cultural heritage. One can see this "porphyry" at facades of a lovely palace of Pavel I and in pedestal of the monument after Nicolas I in St Petersburg. There are many other cases of using this stone in Russia. In Paris, sarcophagus of Napoleon I Bonaparte is constructed of blocks of this stone. Really, it is Proterozoic quartzite. Geology situation, petrography and mineralogical characteristic will be reported too. Comparison with antique porphyre from the Egyptian Province of the Roma Empire is given.

On December 1992, a group of companies headed by Techint, took over Somisa, the state-owned integrated steel plant located at San Nicolas, Province of Buenos Aires, Argentina, culminating an ambitious government privatization scheme. The blast furnace 2 went into a full reconstruction and relining in January 1995. After a 140 MU$ investment the new blast furnace 2 was started in September 1995. After more than one year of operation of the blast furnace the system has proven itself useful and reliable. The main reasons for the success of the system are: same use interface for all blast furnace areas --more » operation, process, maintenance and management, (full horizontal and vertical integration); and full accessibility to all information and process tools though some restrictions apply to field commands (people empowerment). The paper describes the central system.« less

Blindness and the age of enlightenment: Diderot's letter on the blind.

PubMed

Margo, Curtis E; Harman, Lynn E; Smith, Don B

2013-01-01

Several months after anonymously publishing an essay in 1749 with the title "Letter on the Blind for the Use of Those Who Can See," the chief editor of the French Encyclopédie was arrested and taken to the prison fortress of Vincennes just east of Paris, France. The correctly assumed author, Denis Diderot, was 35 years old and had not yet left his imprint on the Age of Enlightenment. His letter, which recounted the life of Nicolas Saunderson, a blind mathematician, was intended to advance secular empiricism and disparage the religiously tinged rationalism put forward by Rene Descartes. The letter's discussion of sensory perception in men born blind dismissed the supposed primacy of visual imagery in abstract thinking. The essay did little to resolve any philosophical controversy, but it marked a turning point in Western attitudes toward visual disability.

Die Bedeutung von Keimen und die richtige Einschätzung ihrer Größe wurden zwar sehr früh bereits durch Paracelsus erkannt, jedoch wurden daraus noch keine speziellen oder kontinuierlich umgesetzten Hygienevorschriften abgeleitet. Die erste bekannte technische Umsetzung von Hygieneempfehlungen geht auf den Franzosen François Nicolas Appert zurück, der eine aseptische Abfüllmethode für Lebensmittel entwickelte und diese 1810 veröffentlichte [1]. Die erste dokumentierte medizinische Umsetzung stellten Hygienevorschriften für Ärzte dar, die Ignaz Philipp Semmelweis nach 1847 in der Wiener Klinik für Geburtshilfe einführte [2].

Although cities cover only 2 percent of the Earth's surface, more than 50 percent of the world's people live in urban environments, collectively consuming 75 percent of the Earth's resources. Because of their population densities, reliance on infrastructure, and role as centers of industry, cities will be greatly impacted by, and will play a large role in, the reduction or exacerbation of climate change. However, although urban dwellers are becoming more aware of the need to reduce their carbon usage and to implement adaptation strategies, education efforts on these strategies have not been comprehensive. To meet the needs of an informed and engaged urban population, a more systemic, multiplatform and coordinated approach is necessary. The Climate and Urban Systems Partnership (CUSP) is designed to explore and address this challenge. Spanning four cities-Philadelphia, New York, Pittsburgh, and Washington, DC-the project is a partnership between the Franklin Institute, the Columbia University Center for Climate Systems Research, the University of Pittsburgh Learning Research and Development Center, Carnegie Museum of Natural History, New York Hall of Science, and the Marian Koshland Science Museum of the National Academy of Sciences. The partnership is developing a comprehensive, interdisciplinary network to educate urban residents about climate science and the urban impacts of climate change.

Unusual Rebuilding Method of Historic St Mary's Cathedral in the Capital of Western Australia

St Mary's Cathedral is the Archbishop church of the Archdiocese in Perth in Western Australia. The presented sacral building was built in neo-Gothic style during the years 1863-1865. Cathedral was officially dedicated and opened for the service on 29th January, 1865. In 1973 was proclaimed the Marian Sanctuary and now represents one of the largest religious facilities in Perth. In 2005, the city authorities, together with the Archdiocese took a collective decision on the necessity of a comprehensive renovation of this sacred object. The renovation was due to the technical condition and the lack of usability of the object. The author of the paper had the opportunity to experience these problems by visiting this place several times, first time in 1989 and next years. Thus, the renovation of the present Cathedral was in its assumption not only to perform maintenance of the building and its specific architectural elements but also to increase its functional features - usable for the faithful and tourists. Reconstruction of St Mary's Cathedral in Perth can be a good example increasing the wider functionality of such facilities while keeping their antique and historical qualities. In this paper the above-mentioned issues will be more widely developed by the author.

Interpreting the paleozoogeography and sea level history of thermally anomalous marine terrace faunas: a case study from the the Last Interglacial Complex of San Clemente Island, California

Marine invertebrate faunas with mixtures of extralimital southern and extralimital northern faunal elements, called thermally anomalous faunas, have been recognized for more than a century in the Quaternary marine terrace record of the Pacific Coast of North America. Although many mechanisms have been proposed to explain this phenomenon, no single explanation seems to be applicable to all localities where thermally anomalous faunas have been observed. Here, we describe one such thermally anomalous fossil fauna that was studied on the second emergent marine terrace at Eel Point on San Clemente Island. The Eel Point terrace complex is a composite feature, consisting of a narrow upper bench (terrace 2a) and a broader lower bench (terrace 2b). Terrace 2b, previously dated from ~128 ka to ~114 ka, was thought to date solely to marine isotope stage (MIS) 5.5, representing the peak of the last interglacial period. Nevertheless, the fauna contains an extralimital northern species and several northward-ranging species, as well as an extralimital southern species and several southward-ranging species. Similar faunas with thermally anomalous elements have also been reported from San Nicolas Island, Point Loma (San Diego County), and Cayucos (San Luis Obispo County), California. U-series dating of corals at those localities shows that the thermally anomalous faunas may be the result of mixing of fossils from both the ~100-ka (cool-water) and the ~120-ka (warm-water) sea level high stands. Submergence, erosion, and fossil mixing of the ~120-ka terraces by the ~100-ka high-sea stand may have been possible due to glacial isostatic adjustment (GIA) effects on North America, which could have resulted in a higher-than-present local sea level stand at ~100 ka. The terrace elevation spacing on San Clemente Island is very similar to that on San Nicolas Island, and we hypothesize that a similar mixing took place on San Clemente Island. Existing fossil records from older terraces

The bacterial mutagenicity of a set of 1993 urban particulate air pollution samples is examined using the Salmonella typhimurium TM677 forward mutation assay. Amibent fine particulate samples were collected for 24 hr every sixth day throughout 1993 at four urban sites, including Long Beach, central Los Angeles, Azusa, and Rubidoux, California, and at an upwind background site on San Nicolas Island. Long Beach and central Los Angeles are congested urban areas where air quality is dominated by fresh emissions from air pollution sources; Azuasa and Rubidoux are located farther downwind and receive transported air pollutants plus increased quantities of the products of atmospheric chemical reactions. Fine aerosol samples from Long Beach and Los Angeles show a pronounced seasonal variation in bacterial mutagenicity per cubic meter of- ambient air, with maximum in the winter and a minimum in the summer. The down-wind smog receptor site at Rubidoux shows peak mutagenicity (with postmitochondrial supernatant but no peak without postmitochondrial supernatant) during the September-October periods when direct transport from upwind sources can be expected. At most sites the mutagenicity per microgram of organic carbon from the aerosol is not obviously higher during the summer photochemical smog period than during the colder months. Significant spatial variation in bacterial mutagenicity is observed: mutagenicity per cubic meter of ambient air, on average, is more than an order of magnitude lower at San Nicolas Island than within the urban area. The highest mutagenicity values per microgram of organics supplied to the assay are found at the most congested urban sites at central Los Angeles and Long Beach. The highest annual average values of mutagenicity per cubic meter of air sampled occur at central Los Angeles. These findings stress the importance of proximity to sources of direct emissions of bacterial mutagens and imply that if important mutagen-forming atmospheric

Since March 1, 2010, French citizens have a new procedure for defending their rights: the Priority preliminary ruling on the issue of constitutionality (QPC). During a trial, any citizen may request that the Constitutional Council be seized if he/she considers that a provision of a law applicable is inconsistent with the Constitution. One of the first QPCs was released regarding the Perruche antijurisprudence provision. The decision of the Supreme Court (Cour de Cassation) on November 17, 2000 had granted the child Nicolas Perruche the right to financial compensation for the material costs related to his physical disability as a result of congenital rubella. In response, Article 1 of the law of March 4, 2002 was passed in order to prohibit the compensation of a child "solely because of his/her birth". Since this law was enacted, only the moral injury of the parents can be indemnified in a case like that of Nicolas Perruche. Over time, the application of this article of the law of March 4, 2002 has become the subject of a heated debate. In the QPC decision of June 11, 2010, the Constitutional Council found the "Perruche antijurisprudence" provision to be consistent with the Constitution, except for the transitional provisions. Thus, it is assumed that the "Perruche antijurisprudence" provision applies to all children born after the entry into force of the law, i.e., as of March 7, 2002. In addition, the Perruche jurisprudence prevails for all claims filed before March 7, 2002. The issue of the cases for which legal action was taken after March 7, 2002 for a child born before March 7, 2002 remains debated. The current debate is whether the implementation of the law of March 4, 2002 should be extended or not to instances subsequent to March 7, 2002 for births prior to that date. In the present state of jurisprudence, the Court of Appeals answers negatively and applies the Perruche jurisprudence to all children born before March 7, 2002, regardless of the date by which

Benjamin Martin, the English natural philosopher, and Claude-Nicolas Le Cat, the French surgeon, both published important work on auditory physiology and function in the mid-eighteenth century. Despite their different backgrounds, there was consensus between the two scholars on key principles of hearing research, most notably the importance of the inner ear in relation to auditory perception. Martin's work (1755 [1763?]) drew directly on the surgical work of Le Cat (1741) to demonstrate the importance of the auditory mechanism in listening processes. Le Cat's interest in the ear, however, came in turn from his interest in surgical anatomy. Martin used Le Cat's elegant designs as a tool for the vivid communication of auditory function to a popular, fee-paying audience. The meeting of two very different minds through intellectual agreement and material transfer demonstrates the way in which principles of hearing science were established in the Enlightenment period.

The country of Mexico is facing serious problems with water quality and supply for human use and consumption in rural communities, mainly due to topographic and isolation. In Mexico the average annual precipitation is 1,500 cubic kilometers of water, if 3% of that amount were used, 13 million Mexicans could be supplied with drinking water that they currently do not have access. Considering the limited infrastructure and management in rural communities, which do not receive services from the centralized systems of large cities, a modified pilot multi-stage filtration (MMSF) system was designed, developed, and evaluated for treating collected rainwater in three rural communities, Ajuchitlan and Villa Nicolas Zapata (Morelos State) and Xacxamayo (Puebla State). The efficiencies obtained in the treatment system were: colour and turbidity >93%. It is worth mentioning that the water obtained for human use and consumption complies with the Mexican Standard NOM-127-SSA1-1994.

Tibiofemoral forces are important in the design and clinical outcomes of TKA. We developed a tibial tray with force transducers and a telemetry system to directly measure tibiofemoral compressive forces in vivo. Knee forces and kinematics traditionally have been measured under laboratory conditions. Although this approach is useful for quantitative measurements and experimental studies, the extrapolation of results to clinical conditions may not always be valid. We therefore developed wearable monitoring equipment and computer algorithms for classifying and identifying unsupervised activities outside the laboratory. Tibial forces were measured for activities of daily living, athletic and recreational activities, and with orthotics and braces, during 4 years postoperatively. Additional measurements included video motion analysis, EMG, fluoroscopic kinematic analysis, and ground reaction force measurement. In vivo measurements were used to evaluate computer models of the knee. Finite element models were used for contact analysis and for computing knee kinematics from measured knee forces. A third-generation system was developed for continuous monitoring of knee forces and kinematics outside the laboratory using a wearable data acquisition hardware. By using measured knee forces and knee flexion angle, we were able to compute femorotibial AP translation (-12 to +4 mm), mediolateral translation (-1 to 1.5 mm), axial rotation (-3° to 12°), and adduction-abduction (-1° to +1°). The neural-network-based classification system was able to identify walking, stair-climbing, sit-to-stand, and stand-to-sit activities with 100% accuracy. Our data may be used to improve existing in vitro models and wear simulators, and enhance prosthetic designs and biomaterials.

An improved version of a recently developed stochastic cluster dynamics (SCD) method (Marian and Bulatov, 2012) [6] is introduced as an alternative to rate theory (RT) methods for solving coupled ordinary differential equation (ODE) systems for irradiation damage simulations. SCD circumvents by design the curse of dimensionality of the variable space that renders traditional ODE-based RT approaches inefficient when handling complex defect population comprised of multiple (more than two) defect species. Several improvements introduced here enable efficient and accurate simulations of irradiated materials up to realistic (high) damage doses characteristic of next-generation nuclear systems. The first improvement is a proceduremore » for efficiently updating the defect reaction-network and event selection in the context of a dynamically expanding reaction-network. Next is a novel implementation of the τ-leaping method that speeds up SCD simulations by advancing the state of the reaction network in large time increments when appropriate. Lastly, a volume rescaling procedure is introduced to control the computational complexity of the expanding reaction-network through occasional reductions of the defect population while maintaining accurate statistics. The enhanced SCD method is then applied to model defect cluster accumulation in iron thin films subjected to triple ion-beam (Fe{sup 3+}, He{sup +} and H{sup +}) irradiations, for which standard RT or spatially-resolved kinetic Monte Carlo simulations are prohibitively expensive.« less

Deactivation via ring opening: A quantum chemical study of the excited states of furan and comparison to thiophene

Minimum nuclear arrangements of the ground and low-lying excited electronic states of furan were obtained by means of (time dependent) Kohn-Sham density functional theory. A combined density functional/multi-reference configuration interaction method (DFT/MRCI) was employed to compute the spectral properties at these points. Multiple minima were found on the first excited singlet (S 1) potential energy hypersurface with electronic structures S1, S2, S3 corresponding to the 1 1A 2 (π → 3s-Ryd), 1 1B 2 (π → π ∗), and 2 1A 1 (π → π ∗) states in the vertical absorption spectrum, respectively. In analogy to recently published studies in thiophene [S. Salzmann, M. Kleinschmidt, J. Tatchen, R. Weinkauf, C.M. Marian, Phys. Chem. Chem. Phys. 10 (2008) 380] a deactivation mechanism for electronically excited furan was detected that involves the opening of the pentacyclic ring. We found a nearly barrierless relaxation pathway from the Franck-Condon region along a C-O bond-breaking coordinate. Hereby the initially excited 1B 2 (π → π ∗) state undergoes a conical intersection with a 1B 1 (π → σ ∗) state. The system can return to the electronic ground state through a second conical intersection of the 1(π → σ ∗) state before the minimum of that B 1 state is reached.

Ephemeral magma chambers in the Trinity peridotite, northern California

NASA Astrophysics Data System (ADS)

Cannat, Mathilde; Lécuyer, Christophe

1991-02-01

The Trinity Massif comprises the major lithologies of an ophiolite, as defined at the 1972 Penrose conference. Previous studies have shown, however, that it differs from the Semail (Oman) or Table Mountain (Newfoundland) ophiolitic massifs, particularly because its crustal section is thin, and because its mantle section has vertical plastic flow planes. These features have led to an interpretation of the Trinity Massif as a fragment of slow-spreading oceanic lithosphere (Le Sueur et al., 1984; Boudier and Nicolas, 1985). In this paper, we show that the Trinity gabbros occur in discontinuous, kilometre-sized pockets, intrusive into the mantle peridotites. The internal stratigraphy and the petrological characteristics of these gabbros suggest that they formed in short-lived magma chambers. These ephemeral magma chambers developed after the end of the plastic deformation in the surrounding mantle, when it had cooled down to lithospheric temperatures. We discuss the possibility that these small and ephemeral magma chambers formed at a slow-spreading oceanic ridge.

Effects of the Ponderomotive Terms in the Thermal Transport on the Hydrodynamic Flow in Inertial Confinement Fusion Experiments

NASA Astrophysics Data System (ADS)

Goncharov, V. N.; Li, G.

2004-11-01

Electron thermal transport is significantly modified by the laser-induced electric fields near the turning point and at the critical surface. It is shown that such modifications lead to an additional limitation in the heat flux in laser-produced plasmas. Furthermore, the ponderomotive terms in the heat flux lead to a steepening in the electron-density profile, which is shown to be a larger effect than the profile modification due to the ponderomotive force [W.L. Kruer, The Physics of Laser--Plasma Interactions, Frontiers in Physics, Vol. 73, edited by D. Pines (Addison-Wesley, Redwood City, CA, 1988)]. To take into account the nonlocal effects, the delocalization model developed in Ref. 2 [G.P. Schurtz, Ph.D. Nicolaï, and M. Busquet, Phys. Plasmas 7, 4238 (2000).] has been applied to conditions relevant to ICF experiments.

A nonlocal, multigroup diffusion model for thermal electron transportfootnotetextG. P. Schurtz, Ph. D. Nicola"i, and M. Busquet, Phys. Plasmas 7, 4238 (2000). has been added to the 2-D hydrodynamic code DRACO. This model has been applied to simulations of polar-drive (PD) NIF ignition designs. Previous simulations were carried out with a constant flux-limiter model in both the radial and transverse directions. Due to the nonsymmetry of PD illumination, these implosions suffer from low-mode nonuniformities that affect their performance. Nonlocal electron transport in both directions is expected to reduce these nonuniformities. The 2-D thermal electron flux from simulations, using either the nonlocal model or the standard flux-limited approach, will be compared and the effect of the nonlocal transport model on the growth of the nonuniformities and on target performance will be presented.

A model of nonlocal transport for multidimensional radiation magnetohydrodynamics codes is presented. In laser produced plasmas, it is now believed that the heat transport can be strongly modified by the nonlocal nature of the electron conduction. Other mechanisms, such as self-generated magnetic fields, may also affect the heat transport. The model described in this work, based on simplified Fokker-Planck equations aims at extending the model of G. Schurtz, Ph. Nicolaï, and M. Busquet [Phys. Plasmas 7, 4238 (2000)] to magnetized plasmas. A complete system of nonlocal equations is derived from kinetic equations with self-consistent electric and magnetic fields. These equations are analyzed and simplified in order to be implemented into large laser fusion codes and coupled to other relevant physics. The model is applied to two laser configurations that demonstrate the main features of the model and point out the nonlocal Righi-Leduc effect in a multidimensional case.

We present a model of nonlocal transport for multidimensional radiation magneto-hydrodynamics codes. This model, based on simplified Fokker-Planck equations, aims at extending the formulae of G Schurtz,Ph.Nicolaï and M. Busquet [Phys. Plasmas,7,4238 (2000)] to magnetized plasmas.The improvements concern various points as the electric field effects on nonlocal transport or conversely the kinetic effects on E field. However the main purpose of this work is to generalize the previous model by including magnetic field effects. A complete system of nonlocal equations is derived from kinetic equations with self-consistent E and B fields. These equations are analyzed and simplified in order to be implemented into large laser fusion codes and coupled to other relevent physics. Finally, our model allows to obtain the deformation of the electron distribution function due to nonlocal effects. This deformation leads to a non-maxwellian function which could be used to compute the influence on other physical processes.

A laser electromagnetic field introduces ponderomotive termsootnotetextV. N. Goncharov and G. Li, Phys. Plasmas 11, 5680 (2004). in the heat flux in a plasma. To account for the nonlocal effects in the ponderomotive terms, first, the kinetic equation coupled with the Maxwell equations is numerically solved for the isotropic part of the electron distribution function. Such an equation includes self-consistent electromagnetic fields and laser absorption through the inverse bremsstrahlung. Then, the anisotropic part is found by solving a simplified Fokker--Planck equation. Using the distribution function, the electric current and heat flux are obtained and substituted into the hydrocode LILAC to simulate ICF implosions. The simulation results are compared against the existing nonlocal electron conduction modelsootnotetextG. P. Schurtz, P. D. Nicola"i, and M. Busquet, Phys. Plasmas 9, 4238 (2000). and Fokker--Planck simulations.

A correct treatment of nonlocal transport in the presence of steep temperature gradients found in laser and inertial fusion plasmas has long been highly desirable over the use of an ad-hoc flux limiter. Therefore, an implementation of the ``SNB'' nonlocal model (G P Schurtz, P D Nicolaï & M Busquet, Phys. Plas. 7, 4238 (2000)) has been benchmarked against a fully-implicit kinetic code: IMPACT. A variety of scenarios, including relaxation of temperature sinusoids and Gaussians in addition to continuous laser heating have been investigated. Results highlight the effect of neglecting electron inertia (∂f1/∂ t) as well as question the feasibility of a nonlocal model that does not continuously track the evolution of the distribution function. Deviations from the Spitzer electric fields used in the model across steep gradients are also investigated. Regimes of validity for such a model are identified and discussed, and possible improvements to the model are suggested.

Phys. 244, 032003 (2010); Di Nicola et al., Proc. SPIE 2015, 93450I-12], at the NIF, focused on Au micro-wires. We show the first hard X-ray radiographs, at photon energies exceeding 60 keV, of static objects obtained with 30 ps-long ARC laser pulses, and the measurements of strength of the X-ray emission, the pulse duration and the source size of the Au micro-wire backlighters. For the latter, a novel technique has been developed and successfully applied.

Sylvester II Bukowiec Observatory: a "piece de theatre" for the inauguration day

NASA Astrophysics Data System (ADS)

Maksym, P. M.

The 21st of May 2010 has been the day of inauguration of the Astronomical Observatory of Bukowiec "Pope Sylvester II". This observatory, a fixed station of the European network of asteroidal and lunar occultations for high resolution astrometry, is built in the territory of the school dedicated to Nicolas Copernicus, the most famous polish astronomer. This new observatory starts its activity in the international year of astronomy, which celebrates the 400th anniversary of the astronomical use of the telescope by Galileo Galilei. The polish astronomer Bohdan Paczy?ski is the fourth protagonist of the pièce théatrale written for the day of inauguration. Here is reported the text of this pièce, which was a powerful way to introduce people to the knowledge of Sylvester II, great scholar and teacher of the 10th century, who founded the first diocesis in Poland when he was Pope.

To determine the distribution of Aedes albopictus (Skuse) in Nuevo Leon between 2001 and 2004. Standardized methods were used to collect 6371 samples of mosquito's larvae from 167 sites. The proportions of samples positive for Ae. albopictus were obtained by municipality and year, using the software program Excel. There were 1179 samples positive for Ae. albopictus. This species was distributed over 10 municipalities, as follows: Five on the Gulf of Mexico Coastal Plains, which predominantly have a semi-warm, sub-humid climate, and precipitations almost year round (Allende, Montemorelos, Linares, General Teran, and Santiago); two (Sabinas Hidalgo, and Cadereyta) localized on the North American Great Plains, which have a warm, semiarid climate, and scarce precipitations. The final three were Apodaca, San Nicolas, and Escobedo distributed over the metropolitan area of Monterrey City. Up to January 2004, the second most important epidemiological vector in the transmission cycle of Ae. albopictus worldwide was found in ten municipalities of Nuevo Leon State, Mexico.

Navy applications experience with small wind power systems

Pal, D.

This report describes the experience gained and lesson learned from the ongoing field evaluations of seven small, 2-to 20-kW wind energy conversion systems (WECS) at Navy installations located in the Southern California desert, on San Nicolas Island, in California, and in Kaneohe Bay, Hawaii. The field tests show that the WECS's bearings and yaw slip-rings are prone to failure. The failures were attributed to the corrosive environment and poor design practices. Based upon the field tests, it is concluded that a reliable WECS must use a permanent magnet alternator without a gearbox and yaw slip-rings that are driven by a fixed pitch wind turbine rotor. The present state-of-the-art in small WECS technology, including environmental concerns, is reviewed. Also presented is how the technology is advancing to improve reliability and availability for effectively using wind power at Navy bases. The field evaluations are continuing on the small WECS in order to develop operation, maintenance, and reliability data.

The Faculty of Pharmacy of Cluj was created in 1948. The first dean was Erwin Popper (1906–1974) – professor of analytical chemistry. At the beginning of the activity the didactic spaces in this institution were not sufficient. Consequently, Prof. Popper tried and succeeded in solving this problem. In 1955–1957, despite financial and economic difficulties, he succeeded in raising a new building for the departments of Analytical Chemistry and Physical Chemistry. The most important part of this edifice was a modern, large and elegant amphitheatre of 200 places. This was the first lecture hall of the Faculty. The historical value of this amphitheatre was completed in 1957 with bass relief carvings, representing important pharmacists and chemists, such as Carol Davila, Ştefan Minovici, Constantin I.

Cold air plasmas of DC and pulsed corona discharges: positive streamers and negative Trichel pulses were used for bio-decontamination of Streptococci biofilm and Bacillus cereus spores on polypropylene plastic surfaces. The reduction of bacterial population (evaluated as log10) in the biofilm on plastic surfaces treated by DC corona reached 2.4 logs with 10 min treatment time and 3.3 logs with 2 min treatment time with water spraying. The enhancement of plasma biocidal effects on the biofilm by electro-spraying of water through a hollow needle high-voltage electrode was investigated. No significant polarity effect was found with DC corona. Pulsed corona was demonstrated slightly more bactericidal for spores, especially in the negative polarity where the bacterial population reduction reached up to 2.2 logs at 10 min exposure time.

Supersaturation, droplet spectra, and turbulent mixing in clouds

NASA Technical Reports Server (NTRS)

Gerber, H.

1990-01-01

Much effort has recently gone into explaining the observed broad precoalescence size distribution of droplets in cloud and fogs, because this differs from the results of condensational growth calculations which lead to much narrower distributions. A good example of droplet size-distribution broadening was observed on flight 17 (25 July) of the NRL tethered balloon during the 1987 FIRE San Nicolas Island IFO. These observations caused the interactions between cloud microphysics and turbulent mixing to be re-examined. The findings of Broadwell and Breidenthal (1982) who conducted laboratory and theoretical studies of mixing in shear flow, and those of Baker et al. (1984) who applied the earlier work to mixing in clouds, were used. Rather than looking at the 25 July case at SNI, earlier fog observations made at SUNY (6 Oct. 1982) which also indicated that shear-induced mixing was taking place, and which had a better collection of microphysical measurements including more precise supersaturation measurements and detailed vertical profiles of meteorological parameters were chosen instead.

Rectal swabs were collected from 31 cats, 16 with FIV infection and 15 uninfected controls, to evaluate and compare the rectal bacterial microbiota in cats with feline immunodeficiency virus (FIV) infection and uninfected controls. The rectal microbiota was characterized via next generation sequencing of 16S rRNA gene (V4 region) polymerase chain reaction products. Eighteen different phyla were identified. Firmicutes dominated in both groups, followed by Proteobacteria and Actinobacteria, but there were no significant differences between groups. When predominant orders are compared, FIV-infected cats had significant higher median relative abundances of Bifidobacteriales (P=0.022), Lactobacillales (P=0.022) and Aeromonadales (P=0.043). No differences were identified in the 50 most common genera when adjusted for false discovery rate. There were significant differences in community membership (Jaccard index, unifrac P=0.008, AMOVA P<0.001) and community structure (Yue&Clayton index, unifrac P=0.03, AMOVA P=0.005) between groups. However, only one metacommunity (enterotype) was identified. The rectal microbiota differed between cats with FIV infection and uninfected controls. Some of the changes that were noted have been associated with 'dysbiosis' and proinflammatory states in other species, so it is possible that subclinical alteration in the intestinal microbiota could influence the health of FIV-infected cats. Evaluation of the reasons for microbiota alteration and the potential impact on cat health is required. Copyright © 2015 Elsevier B.V. All rights reserved.

Topological Ordering and Viscosity in the Glassy Ge-Se System: The Search for a Structural or Dynamical Signature of the Intermediate Phase

The topological ordering of the network structure in vitreous Ge_xSe_{1-x} was investigated across most of the glass-forming region (0 ≤ x ≤ 0.4) by using high-resolution neutron diffraction to measure the Bhatia-Thornton number-number partial structure factor. This approach gives access to the composition dependence of the mean coordination number \\bar{n} and correlation lengths associated with the network ordering. The thermal properties of the samples were also measured by using temperature-modulated differential scanning calorimetry. The results do not point to a structural origin of the so-called intermediate phase, which in our work is indicated for the composition range 0.175(8) ≤ x ≤ 0.235(8) by a vanishingly-small non-reversing enthalpy near the glass transition. The midpoint of this range coincides with the mean-field expectation of a floppy-to-rigid transition at x = 0.20. The composition dependence of the liquid viscosity, as taken from the literature, was also investigated to look for a dynamical origin of the intermediate phase, using the Mauro-Yue-Ellison-Gupta-Allan (MYEGA) model to estimate the viscosity at the liquidus temperature. The evidence points to a maximum in the viscosity at the liquidus temperature, and a minimum in the fragility index, for the range 0.20 ≤ x ≤ 0.22. The utility of the intermediate phase as a predictor of the material properties in network glass-forming systems is discussed.

Ion Internal Excitation and Co++ 2 Reactivity: Effect On The Titan, Mars and Venus Ionospheric Chemistry

NASA Astrophysics Data System (ADS)

Nicolas, C.; Zabka, J.; Thissen, R.; Dutuit, O.; Alcaraz, C.

In planetary ionospheres, primary molecular and atomic photoions can be produced with substantial electronic and vibrational internal energy. In some cases, this is known to strongly affect both the rate constants and the branching ratio between the reac- tion products. A previous experimental study (Nicolas et al.) made at the Orsay syn- chrotron radiation facility has shown that many endothermic charge transfer reactions which were not considered in the ionospheric chemistry models of Mars, Venus and Earth have to be included because they are driven by electronic excitation of the parent ions. New measurements on two important reactions for Titan and Mars ionospheres, N+ + CH4 and O+ + CO2, will be presented. Branching ratios between products are very different when the parent atomic ions are prepared in their ground states, N+(3P) and O+(4S), or in their first electronic metastable states N+(1D) and O+(2D or P). 2 As the lifetime of these states are long enough, they survive during the mean time be- tween two collisions in the ionospheric conditions. So, the reactions of these excited states must be included in the ionospheric models. Absolute cross section measurements of the reactivity of stable doubly charged molec- ular ions CO++ and their implications for the Martian ionosphere will also be pre- 2 sented. The molecular dication CO++ production by VUV photoionisation and elec- 2 tron impact in the upper ionosphere of Mars is far from being negligible. However, to determine its concentration, it was necessary to evaluate the major loss channels of these ions. For this purpose, we measured the absolute reaction cross section of the sta- ble dications with CO2, the major neutral species of the Mars ionosphere. CO++ ions 2 were produced either by photoionisation or by electron impact, and a reaction cross section of 45 Å2 with 13CO2 was measured. The reaction leads to charge transfer or to collision induced dissociation. These results were integrated in a model

Neuropsychiatric phenomena in the medieval text Cantigas de Santa Maria.

To discuss the neuropsychiatric phenomena described in Cantigas de Santa Maria (Canticles of St. Mary [CSM]). CSM is a collection of 427 canticles composed in Galician-Portuguese between 1252 and 1284 at the Court of King Alfonso X the Wise of Spain (1221-1284). The canticles (of which 9 are repeated) include devotional and liturgical poems and 353 narrative stories consisting mainly of depictions of Marian miracles. Most are set to music and many are illustrated. We reviewed the canticles for description of miracles and other neuropsychiatric phenomena. Two neurologists reached a consensus about the descriptions. Of the 353 miracles, 279 medically relevant facts (from 187 canticles) and 25 instances of resurrection were reported. Possible neuropsychiatric conditions were described in 98 canticles. Physicians were mentioned in 16 narratives. The most common neurologic conditions detailed were blindness (n = 17), dystonia, weakness, and deformities (n = 20). Other common conditions included psychosis (n = 15), speech disorder/deaf-mutism (n = 12), infections (n = 15), sexual dysfunction/infertility/obstetrical-gynecologic issues (n = 18), head trauma (n = 5), ergotism/St. Anthony's fire (n = 7), and others. There were 9 instances of prodromic mystical experiences/hallucinations heralding death. While limited by retrospection and interpretation of neuropsychiatric phenomena in the medieval context, these short accounts are among the first descriptions of neuropsychiatric conditions in early Portuguese/Galician. They reflect how medieval societies used rational and irrational approaches to understand occurrences in their lives. © 2015 American Academy of Neurology.

The economics of well-being.

PubMed

Fox, Justin

2012-01-01

Gross domestic product has long been the chief measure of national success. But there's been a lot of talk lately about changing that, from economists and world leaders alike. GDP is under siege for three main reasons. First, it is flawed even on its own terms: It misses lots of economic activity (unpaid household work, for example) and, as a single-number representation of vast, complex systems, is inevitably skewed. Second, it fails to account for economic and environmental sustainability. And third, readily available alternative measures may reflect well-being far better, by taking into account factors such as educational achievement, health, and life expectancy. HBR's Justin Fox surveys historical and current views on how to assess national progress, from Jeremy Bentham to Robert Kennedy to Nicolas Sarkozy. He also looks at where we may be headed. The biggest success so far in the campaign to supplant or at least supplement GDP, he finds, is the UN's Human Development Index-on which the United States has never claimed the top spot.

The surface of carbon-steel plates was modified by non-equilibrium plasma of diffuse coplanar surface barrier discharge (DCSBD) in order to improve the adhesive properties to the NR (natural rubber) green rubber compound. The effect of different treatment times as well as different input power and frequency of supplied high voltage was investigated. The samples were characterized using contact angle and surface free energy measurement, measurement of adhesive properties, scanning electron microscopy (SEM) and atomic force microscopy (AFM). Surface chemical composition was studied by energy-dispersive X-ray spectroscopy (EDX). Significant increase in wettability was observed even after 2 s of plasma exposure. The surface modification was confirmed also by peel test, where the best results were obtained for 6 s of plasma treatment. In addition the ageing effect was studied to investigate the durability of modification, which is crucial for the industrial applications.

We developed a portable ozone-mist sterilization system to exterminate pests (harmful insects) in agricultural field and greenhouse. The system is composed of an ozone generator, an ozone-mist spray and a small container of ozone gas. The ozone generator can supply highly concentrated ozone using the surface dielectric barrier discharge. Ozone-mist is produced using a developed nozzle system. We studied the effects of ozone-mist spray sterilization on insects and agricultural plants. The sterilization conditions are estimated by monitoring the behavior of aphids and observing the damage of the plants. It was shown that aphids were exterminated in 30 s without noticeable damages of the plant leaves. The reactive radicals with strong oxidation potential such as hydroxyl radical (*OH), hydroperoxide radical (*HO2), the superoxide ion radical (*O2‒) and ozonide radical ion (*O3‒) can increase the sterilization rate for aphids.

Soil humus and carbon popularity from 1804 (N. de Saussure) to 2015 (COP 21)

NASA Astrophysics Data System (ADS)

Feller, Christian; Brevik, Eric

2017-04-01

The popularity of humus (or soil organic matter SOM) and later on soil organic carbon (SOC) as related to plant nutrition, soil fertility and environment varied widely from the beginning of the 19th century with the research of Nicolas de Saussure (1804) to Thaer's humus theory (1809) followed by Liebig's mineral theory (1840) until the 20th century with new perceptions of the beneficial roles of SOM. Nowadays, it is known that SOM (with SOC) participates in multiple interactions with the other Earth ecosystem compartments (hydrosphere, biosphere, atmosphere lithosphere). Very recently SOM and SOC were raised to the summit of the international challenges concerning global changes with the French initiative entitled "4 per 1000". Therefore, from the past to the present humus has received varying levels of consideration regarding its benefits for humanity. The central questions of this presentation will be: 1) What were the links between science and society at each of these epistemological steps during these last 200 years, and 2) what were the scientific theories involved?

Microbiological Spoilage of Canned Foods

NASA Astrophysics Data System (ADS)

Evancho, George M.; Tortorelli, Suzanne; Scott, Virginia N.

Nicolas Appert (1749-1841) developed the first commercial process that kept foods from spoiling in response to an offer from the French government for a method of preserving food for use by the army and navy. Appert, a confectioner and chef, began to experiment in his workshop in Massy, near Paris, but since little was known about bacteriology and the causes of spoilage (Louis Pasteur had yet to formulate the germ theory), much of his work involved trial and error. In 1810, after years of experimenting, he was awarded the prize of 12,000 francs for his method of preservation, which involved cooking foods in sealed jars at high temperatures. He described his method of preserving food in a book published in 1811, "L'Art De Conserver, Pendant Plusiers Annes, Toutes les Substances Animales et Végétales," which translated means "The Art of Preserving All Kinds of Animal and Vegetable Substances for Several Years." He later built a bottling factory and began to produce preserved foods for the people of France and is credited with being the "Father of Canning."

A simple method for preparation of nanoparticle incorporated non-woven fabric with high antibacterial efficiency has been proposed based on atmospheric pressure plasma process. In this work direct current plasma jet stabilized by fast nitrogen flow was used as a plasma deposition source. Three different types of the nanoparticles (silver, copper and zinc oxide nanoparticles) were employed as antimicrobial agents. X-ray photoelectron spectroscopy (XPS) measurements have shown a positive chemical shift observed for Ag 3d 5/2 (at 368.1 eV) suggests that silver nanoparticles (AgNPs) are partly oxidized during the deposition. The surface chemistry and the antibacterial activity of the samples against Staphylococcus aureus and Escherichia coli were investigated and analyzed. It is shown that the samples loaded with nanoparticles of Ag and Cu and having the barrier layer of 10 nm characterized by almost 97% of bacterial reduction whereas the samples with ZnO nanoparticles provide 86% reduction of Staphylococcus aureus.

Nicolas Steno, a seventeenth-century Danish Catholic bishop and scientist, is considered a founder of modern stratigraphy and geology for his work on linking modern shark teeth to objects found in rock formations, among many other studies and writings. Steno, whose non-Latinized name was Niels Stensen, gained newfound fame as the inspiration for a Google doodle published on 11 January to mark his 374th birthday. The doodle of the Google logo is a rainbow-colored block letter formation that suggests karst stratigraphic layers chock with fossils and shells. How did Steno end up being honored in this way? “The criteria for selecting a doodle subject are pretty simple: We like to celebrate anything that is geeky, quirky, and artistic,” Google's Jennifer Hom, who drew the doodle, told Eos. “Nicholas Steno happened to be a really geeky and innovative thinker whose work on stratigraphy is also visually interesting. Not only does he relate to our Google culture in that he was a groundbreaking (no pun intended) scientist, his work is also very artistically inspiring.”

Foucault at the bedside: a critical analysis of empowering a healthy lifestyle.

Devisch, Ignaas; Vanheule, Stijn

Since quite a few years, philosophy is heading towards the bedside of the patient: the practice of philosophy has stepped out of its ivory tower, it seems, to deal with empirical or practical questions. Apart from the advantages, we should keep in mind the importance of a critical analysis of medical or clinical practice as such. If ethics partakes the clinical stage, it runs the risk only to discuss the how question and to forget the more fundamental what or why questions: what are we doing exactly and why is it good for? Starting from the principle of the empowerment of the patient, we will demonstrate how the discourse on empowerment in health care seems to forget a profound reflection upon this principle as such. By rehearsing some basics from the governmentality theory of Michel Foucault and the actualization of it by Nicolas Rose, we will argue how philosophical investigation in medical-ethical evolutions such as empowerment of the patient is still needed to understand what is really going on in today's clinical practice. © 2015 John Wiley & Sons, Ltd.

A communication efficient and scalable distributed data mining for the astronomical data

Govada, A.; Sahay, S. K.

2016-07-01

In 2020, ∼60PB of archived data will be accessible to the astronomers. But to analyze such a paramount data will be a challenging task. This is basically due to the computational model used to download the data from complex geographically distributed archives to a central site and then analyzing it in the local systems. Because the data has to be downloaded to the central site, the network BW limitation will be a hindrance for the scientific discoveries. Also analyzing this PB-scale on local machines in a centralized manner is challenging. In this, virtual observatory is a step towards this problem, however, it does not provide the data mining model (Zhang et al., 2004). Adding the distributed data mining layer to the VO can be the solution in which the knowledge can be downloaded by the astronomers instead the raw data and thereafter astronomers can either reconstruct the data back from the downloaded knowledge or use the knowledge directly for further analysis. Therefore, in this paper, we present Distributed Load Balancing Principal Component Analysis for optimally distributing the computation among the available nodes to minimize the transmission cost and downloading cost for the end user. The experimental analysis is done with Fundamental Plane (FP) data, Gadotti data and complex Mfeat data. In terms of transmission cost, our approach performs better than Qi et al. and Yue et al. The analysis shows that with the complex Mfeat data ∼90% downloading cost can be reduced for the end user with the negligible loss in accuracy.

Mass flow rate measurements in gas-liquid flows by means of a venturi or orifice plate coupled to a void fraction sensor

Oliveira, Jorge Luiz Goes; Passos, Julio Cesar; Verschaeren, Ruud

Two-phase flow measurements were carried out using a resistive void fraction meter coupled to a venturi or orifice plate. The measurement system used to estimate the liquid and gas mass flow rates was evaluated using an air-water experimental facility. Experiments included upward vertical and horizontal flow, annular, bubbly, churn and slug patterns, void fraction ranging from 2% to 85%, water flow rate up to 4000 kg/h, air flow rate up to 50 kg/h, and quality up to almost 10%. The fractional root mean square (RMS) deviation of the two-phase mass flow rate in upward vertical flow through a venturi platemore » is 6.8% using the correlation of Chisholm (D. Chisholm, Pressure gradients during the flow of incompressible two-phase mixtures through pipes, venturis and orifice plates, British Chemical Engineering 12 (9) (1967) 454-457). For the orifice plate, the RMS deviation of the vertical flow is 5.5% using the correlation of Zhang et al. (H.J. Zhang, W.T. Yue, Z.Y. Huang, Investigation of oil-air two-phase mass flow rate measurement using venturi and void fraction sensor, Journal of Zhejiang University Science 6A (6) (2005) 601-606). The results show that the flow direction has no significant influence on the meters in relation to the pressure drop in the experimental operation range. Quality and slip ratio analyses were also performed. The results show a mean slip ratio lower than 1.1, when bubbly and slug flow patterns are encountered for mean void fractions lower than 70%.

The instrument consist of two detectors-the high energy electrons instrument which can measure 200keV to greater than 4MeV electrons with eleven channels, and the high energy protons and heavy ions instrument which mainly senses incident flux of solar protons with seven channels from 4MeV to 300 MeV. The paper shows electrons and protons observations from Jan 2015 until Oct 2015. A precise description and preliminary analysis of particle dynamic during disturbances of magnetic storms、substorms and solar eruptions suggest that both of the detectors show accurate response to various disturbances and provide refined particles data. Comparison results of FY2G satellite with GOES series satellites reflect obvious local difference in particle flux evolvement especially during intensive disturbances time, which can be helpful for data assimilation of multi-satellite as well as further research in more complicated magnetosphere energy particle dynamic.

On the fast zonal transport of the STS-121 space shuttle exhaust plume in the lower thermosphere

Meier et al. (2011) reported rapid eastward transport of the STS-121 space shuttle (launch: July 4, 2006) main engine plume in the lower thermosphere, observed in hydrogen Lyman α images by the GUVI instrument onboard the TIMED satellite. In order to study the mechanism of the rapid zonal transport, diagnostic tracer calculations are performed using winds from the Thermosphere Ionosphere Mesosphere Electrodynamics General Circulation Model (TIME-GCM) simulation of July, 2006. It is found that the strong eastward jet at heights of 100-110 km, where the exhaust plume was deposited, results in a persistent eastward tracer motion with an average velocity of 45 m/s. This is generally consistent with, though faster than, the prevailing eastward shuttle plume movement with daily mean velocity of 30 m/s deduced from the STS-121 GUVI observation. The quasi-two-day wave (QTDW) was not included in the numerical simulation because it was found not to be large. Its absence, however, might be partially responsible for insufficient meridional transport to move the tracers away from the fast jet in the simulation. The current study and our model results from Yue and Liu (2010) explain two very different shuttle plume transport scenarios (STS-121 and STS-107 (launch: January 16, 2003), respectively): we conclude that lower thermospheric dynamics is sufficient to account for both very fast zonal motion (zonal jet in the case of STS-121) and very fast meridional motion to polar regions (large QTDW in the case of STS-107).

2004-01-01

The oral health of astronauts, last studied in the mid- 1970s on Skylab, has not been a priority area of study for NASA due to the short length of shuttle stays. But with longer stays on the International Space Station, and planning for a trip to Mars, investigations into how spaceflight affects oral health are needed. The objective of this symposium is to introduce the dental research community to changes occurring in humans who go into space, and how these changes might impact oral health. Dr. Millie Hughes-Fulford, an astronaut-scientist, will review what happens to humans who go into space, and the difficulties of living, and carrying out experiments in space. She will then discuss her research on cell cultures of osteoblasts in space, and in hypergravity Dr. Gerald Sonnenfeld will review immunological changes that occur in spaceflight, and relate the observed decreases in various types of immunological responses to possible effects on oral immunological factors. Dr. Marian Lewis will discuss the effects of spaceflight on gene expression using results from her spaceflight experiments on various cell types. Dr. Jack van Loon, fiom the Dutch Experiment Support Center, will review what is known about bone loss in humans and rats and metatarsal cultures which go into space, and review ground based models (head down bedrest, and tail suspension) that simulate the unloading of spaceflight. Attendees will gain a knowledge of spaceflight research, and information on getting their own experiments in space. The symposium is supported by the NASA Office of Bioastronautics

Heat flux variations over sea-ice observed at the coastal area of the Sejong Station, Antarctica

2012-12-01

This study presents variations of sensible heat flux and latent heat flux over sea-ice observed in 2011 from the 10-m flux tower located at the coast of the Sejong Station on King George Island, Antarctica. A period from June to November was divided into three parts: "Freezing", "Frozen", and "Melting" periods based on daily monitoring of sea state and hourly photos looking at the Marian Cove in front of the Sejong Station. The division of periods enabled us to look into the heat flux variations depending on the sea-ice conditions. Over freezing sea surface during the freezing period of late June, daily mean sensible heat flux was -11.9 Wm-2 and daily mean latent heat flux was +16.3 Wm-2. Over the frozen sea-ice, daily mean sensible heat flux was -10.4 Wm-2 while daily mean latent heat flux was +2.4 Wm-2. During the melting period of mid-October to early November, magnitudes of sensible heat flux increased to -14.2 Wm-2 and latent heat flux also increased to +13.5 Wm-2. In short, latent heat flux was usually upward over sea-ice most of the time while sensible heat flux was downward from atmosphere to sea-ice. Magnitudes of the fluxes were small but increased when freezing or melting of sea-ice was occurring. Especially, latent heat flux increased five to six times compared to that of "frozen" period implying that early melting of sea-ice may cause five to six times larger supply of moisture to the atmosphere.

The Hetu'u Global Network: Measuring the Distance to the Sun with the Transit of Venus

Rodriguez, David; Faherty, J.

2013-01-01

In the spirit of historic astronomical endeavors, we invited school groups across the globe to collaborate in a solar distance measurement using the 2012 transit of Venus. In total, our group (stationed at Easter Island, Chile) recruited 19 school groups spread over 6 continents and 10 countries to participate in our Hetu’u Global Network. Applying the methods of French astronomer Joseph-Nicolas Delisle, we used individual second and third Venus-Sun contact times to calculate the distance to the Sun. Ten of the sites in our network had amiable weather; 8 of which measured second contact and 5 of which measured third contact leading to consistent solar distance measurements of 152+/-30 million km and 163+/-30 million km respectively. The distance to the Sun at the time of the transit was 152.25 million km; therefore, our measurements are also consistent within 1-sigma of the known value. The goal of our international school group network was to inspire the next generation of scientists using the excitement and accessibility of such a rare astronomical event. In the process, we connected hundreds of participating students representing a diverse, multi-cultural group with differing political, economic, and racial backgrounds.

Organic materials used for packing food products prevent the access of microorganisms or gases, like oxygen or water vapor. To prolong the stability of products, preservatives such as sulfur dioxide, sulfites, benzoates, nitrites and many other chemical compounds are used. To eliminate or limit the amount of preservatives added to food, so-called active packaging is sought for, which would limit the development of microorganisms. Such packaging can be achieved, among others, by plasma modification of a material to deposit on its surface substances inhibiting the growth of bacteria. In this work plasma modification was carried out in barrier discharge under atmospheric pressure. Sulfur dioxide or/and sodium oxide were used as the coating precursors. As a result of bacteriological studies it was found that sulfur containing coatings show a 16% inhibition of Salmonella bacteria growth and 8% inhibition of Staphylococcus aureus bacteria growth. Sodium containing coatings show worse (by 10%) inhibiting properties. Moreover, films with plasma deposited coatings show good sealing properties against water vapor.

Has psychology "found its true path"? Methods, objectivity, and cries of "crisis" in early twentieth-century French psychology.

PubMed

Carson, John

2012-06-01

This article explores how French psychologists understood the state of their field during the first quarter of the twentieth century, and whether they thought it was in crisis. The article begins with the Russian-born psychologist Nicolas Kostyleff and his announcement in 1911 that experimental psychology was facing a crisis. After briefly situating Kostyleff, the article examines his analysis of the troubles facing experimental psychology and his proposed solution, as well as the rather muted response his diagnosis received from the French psychological community. The optimism about the field evident in many of the accounts surveying French psychology during the early twentieth century notwithstanding, a few others did join Kostyleff in declaring that all was not well with experimental psychology. Together their pronouncements suggest that under the surface, important unresolved issues faced the French psychological community. Two are singled out: What was the proper methodology for psychology as a positive science? And what kinds of practices could claim to be objective, and in what sense? The article concludes by examining what these anxieties reveal about the type of science that French psychologists hoped to pursue. Copyright © 2011 Elsevier Ltd. All rights reserved.

Strasbourg occupied during the 19th century a privileged place in chemistry, as well in education as in research, and that in particular in three institutions created after the dissolution of the old University during the French Revolution: the Faculty of Sciences, the School then Faculty of Medicine created in 1794, and the School of Pharmacy created in 1804. In 1871, Alsace was annexed by Germany. The chair of medical chemistry in the Faculty of Medicine was successively occupied by: Pierre François Nicolas (1743-1816) in 1794-1795, Frédéric Louis Ehrmann (1741-1801) from 1796 to 1798, Gabriel Masuyer (1761-1849) from 1798 to 1838, and Amédée Cailliot (1805-1884) from 1838 to 1871. The chair of chemistry in the School of Pharmacy was successively occupied by: Louis Hecht (1771-1857)from 1804 to 1835, Jean François Persoz (1805-1868) from 1835 to 1852, Adrien Loir (1816-1899) from 1852 to 1855, Charles Frédéric Gerhardt and Eugène Théodore Jacquemin (1828-1909) from 1856 to 1871.

The oil and fat were treated at first by only ozone bubbling and it was confirmed that the collection efficiency of them became 98.4% when the aeration was used. It showed that the aeration method in a grease trap cleared the standard value of 90% and there was no worry on the oil and fat outflow from a grease trap. The characteristics of sonication process were studied for free fatty acids degradation. The free saturated fatty acids are the most hard-degradable compounds of the fats, oils and greases (FOGs) in the grease trap. The influence of various parameters such as immersion level of an ultrasound probe in the liquid and bubbling of various gases (Ar, O2, air, O3) on the sonochemical and energy efficiency of the sonication process was investigated. The most effective degradation treatment method for saturated free fatty acids was the combination of sonication and low flow rate argon bubbling.

2008-03-01

Magnetoelectric materials experienced a recent revival as promising components of novel spintronic devices [1, 2, 3]. Since the magnetoelectric (ME) effect is relativistically small in traditional antiferromagnetic compounds like Cr2O3 (max. αzz 4ps/m ) and also cross- coupling between ferroic order parameters is typically small in the modern multiferroics, it is a challenge to electrically induce sufficient magnetization required for the envisioned device applications. A straightforward approach is to increase the electric field at constant voltage by reducing the thickness of the ME material to thin films of a few nm. Since magnetism is known to be affected by geometrical confinement thickness dependence of the ME effect in thin film Cr2O3 is expected. We grow (111) textured Cr2O3 films with various thicknesses below 500 nm and study the ME effect for various ME annealing conditions as a function of temperature with the help of Kerr-magnetometry.

Hearing the irrational: music and the development of the modern concept of number.

PubMed

Pesic, Peter

2010-09-01

Because the modern concept of number emerged within a quadrivium that included music alongside arithmetic, geometry, and astronomy, musical considerations affected mathematical developments. Michael Stifel embedded the then-paradoxical term "irrational numbers" (numerici irrationales) in a musical context (1544), though his philosophical aversion to the "cloud of infinity" surrounding such numbers finally outweighed his musical arguments in their favor. Girolamo Cardano gave the same status to irrational and rational quantities in his algebra (1545), for which his contemporaneous work on music suggested parallels and empirical examples. Nicola Vicentino's attempt to revive ancient "enharmonic" music (1555) required and hence defended the use of "irrational proportions" (proportiones inrationales) as if they were numbers. These developments emerged in richly interactive social and cultural milieus whose participants interwove musical and mathematical interests so closely that their intense controversies about ancient Greek music had repercussions for mathematics as well. The musical interests of Stifel, Cardano, and Vicentino influenced their respective treatments of "irrational numbers." Practical as well as theoretical music both invited and opened the way for the recognition of a radically new concept of number, even in the teeth of paradox.

Effect of nitrogen addition to ozone generation characteristics by diffuse and filamentary dielectric barrier discharges at atmospheric pressure

2017-05-01

Ozone is widely used for gas treatment, advanced oxidation processes, microorganisms inactivation, etc. In this research, we investigated the effect of nitrogen addition to ozone generation characteristics by atmospheric pressure Townsend discharge (APTD) type and filamentary dielectric barrier discharge (DBD) type ozone generators. The result showed that the ozone generated by the filamentary DBD increases rapidly with the increase of O2 content, and is higher than that by the APTD. On the other hand, it is interesting that the ozone generated by the APTD gradually decreases with the increase of O2 content. In order to clarify why the characteristics of ozone generation by the two kinds of discharge modes showed different dependency to the N2 content, we analyzed the exhaust gas composition using FTIR spectroscopy and calculated the rate coefficients using BOLSIG+ code. As a result, we found that although O2 content decreased with increasing N2 content, additional O atoms produced by excited N2 molecules contribute to ozone generation in case of APTD.

Transition from diffuse to self-organized discharge in a high frequency dielectric barrier discharge

NASA Astrophysics Data System (ADS)

Belinger, Antoine; Naudé, Nicolas; Gherardi, Nicolas

2017-05-01

Depending on the operating conditions, different regimes can be obtained in a dielectric barrier discharge (DBD): filamentary, diffuse (also called homogeneous) or self-organized. For a plane-to-plane DBD operated at high frequency (160 kHz) and at atmospheric pressure in helium gas, we show that the addition of a small amount of nitrogen induces a transition from the diffuse regime to a self-organized regime characterized by the appearance of filaments at the exit of the discharge. In this paper, we detail mechanisms that could be responsible of the transition from diffuse mode to this self-organized mode. We point out the critical role of the power supply and the importance of the gas memory effect from one discharge to the following one on the transition to the self-organised mode. The self-organized mode is usually attributed to a surface memory effect. In this work, we show an additional involvement of the gas memory effect on the self-organized mode.

Multi-shock experiments on a TATB-based composition

Sorin, Remy

2017-06-01

Temperature based models for condensed explosive need an unreacted equation of state (EOS) that allows a realistic estimation of the temperature for a shock compression driven at detonation velocity. To feed the detonation models, we aim at exploring the high pressure shock Hugoniot of unreacted TATB composition up to 30 GPa with both hydrodynamic and temperature measurements. We performed on the gas gun facility ARES, multi-shock experiments where the first shock is designed to desensitize the explosive and inhibit the reactivity of the composition. The hydrodynamic behavior was measured via the velocity of a TATB/LiF interface with PDV probes. We attempted to measure the temperature of the shocked material via surface emissivity with a pyrometer calibrated to the expected low temperature range. Based on single shock experiments and on ab-initio calculation, we built a complete EOS for the unreacted phase of the TATB explosive. The hydrodynamic data are in good agreement with our unreacted EOS. Despite the record of multi-stage emissivity signals, the temperature measurements were difficult to interpret dur to high-luminisity phenomena pertubation.

René Nicolas Dufriche Desgenettes (1762-1837) became famous through two historical events: the first and most famous one is where he proved his courage by inoculating himself with the plague during the Syrian campaign in 1799; the second one, rarely represented in paintings, happened during the Russian retreat in 1812 when he was freed thanks to his reputation. Two wide fresco paintings facing each other in the hall of Desgenettes, a hospital built during World War Two, are witnesses of these two major events. Jean Coquet (1907-1990), a decorator, painter and glassblower, who worked at the Beaux-Arts School of Lyon, first as a decoration teacher than as its director, painted these two works of art. In 1946, he inserted them into an ornamental group constituted of ironworks, furniture, stained glass and ceramics. Two paintings from Antoine-Jean Gros (1771-1835) inspired these works: Bonaparte visiting the plague-stricken of Jaffa (1804) and Napoleon on the battlefield of Eylau (1808). With their academic composition and daring stylization those two frescoes represent in a modern and original way Desgenettes' life style, an archetype of what the military doctor is.

Understanding the importance of the temperature dependence of viscosity on the crystallization dynamics in the Ge2Sb2Te5 phase-change material

NASA Astrophysics Data System (ADS)

Aladool, A.; Aziz, M. M.; Wright, C. D.

2017-06-01

The crystallization dynamics in the phase-change material Ge2Sb2Te5 is modelled using the more detailed Master equation method over a wide range of heating rates commensurate with published ultrafast calorimetry experiments. Through the attachment and detachment of monomers, the Master rate equation naturally traces nucleation and growth of crystallites with temperature history to calculate the transient distribution of cluster sizes in the material. Both the attachment and detachment rates in this theory are strong functions of viscosity, and thus, the value of viscosity and its dependence on temperature significantly affect the crystallization process. In this paper, we use the physically realistic Mauro-Yue-Ellison-Gupta-Allan viscosity model in the Master equation approach to study the role of the viscosity model parameters on the crystallization dynamics in Ge2Sb2Te5 under ramped annealing conditions with heating rates up to 4 × 104 K/s. Furthermore, due to the relatively low computational cost of the Master equation method compared to atomistic level computations, an iterative numerical approach was developed to fit theoretical Kissinger plots simulated with the Master equation system to experimental Kissinger plots from ultrafast calorimetry measurements at increasing heating rates. This provided a more rigorous method (incorporating both nucleation and growth processes) to extract the viscosity model parameters from the analysis of experimental data. The simulations and analysis revealed the strong coupling between the glass transition temperature and fragility index in the viscosity and crystallization models and highlighted the role of the dependence of the glass transition temperature on the heating rate for the accurate estimation of the fragility index of phase-change materials from the analysis of experimental measurements.

The seismic interpretation supported by in-depth facies analysis permitted to depict the potential depositional environments offshore Lebanon as no well has yet been drilled. The Levant region has been affected by successive geodynamic events that modified the architecture of its margin and basin from a Late Triassic to Middle Jurassic rift into a Late Cretaceous subduction followed by collision and Miocene-Present strike slip motion. The interplay between major geodynamic events as well as sea level fluctuations impacted on the sedimentary infill of the basin. During Jurassic and Cretaceous, the Levant Margin is dominated by the aggradation of a carbonate platform while deepwater mixed-systems prevailed in the basin. During the Oligo-Miocene, three major sedimentary pathways are expected to drive important

Human immunodeficiency virus (HIV) infection is associated with a range of oral conditions, and increased numbers of disease-associated microbial species have previously been found in HIV-positive subjects. The aim of this study was to use next-generation sequencing to compare the composition of the oral microbiome in HIV-positive and -negative individuals. Plaque and saliva were collected from 37 HIV-positive individuals and 37 HIV-negative individuals, and their bacterial composition determined by pyrosequencing of partial 16S rRNA genes. A total of 855,222 sequences were analysed. The number of species-level operational taxonomic units (OTUs) detected was significantly lower in the saliva of HIV-positive individuals (mean = 303.3) than in that of HIV-negative individuals (mean = 365.5) (P < 0.0003). Principal coordinates analysis (PCoA) based on community membership (Jaccard index) and structure (Yue and Clayton measure of dissimilarity) showed significant separation of plaque and saliva samples [analysis of molecular variance (AMOVA), P < 0.001]. PCoA plots did not show any clear separation based on HIV status. However, AMOVA indicated that there was a significant difference in the community membership of saliva between HIV-positive and -negative groups (P = 0.001). Linear discriminant analysis effect size revealed an OTU identified as Haemophilus parainfluenzae to be significantly associated with HIV-positive individuals, whilst Streptococcus mitis/HOT473 was most significantly associated with HIV-negative individuals. In conclusion, this study has confirmed that the microbial composition of saliva and plaque is different. The oral microbiomes of HIV-positive and -negative individuals were found to be similar overall, although there were minor but significant differences in the composition of the salivary microbiota of the two groups.

To collect Li Shizhen's experience in Aconiti Lateralis Radix Praeparata identification and clinical application, compare and analyze national physician master Jin Shiyuan's practical operation and theoretical knowledge, which is beneficial for the inheritance and improvement of Aconiti Lateralis Radix Praeparata clinical dispensing technology. In the analysis process, CNKI, Wanfang and other databases were searched with "Aconiti Lateralis Radix Praeparata", "Li Shizhen", "pharmacological method state theory" "Jin Shiyuan" and "Chinese medicine dispensing technology" as the key words. In addition, Treatise on Febrile Disease, Compendium of Materia Medica, Chinese Pharmacopoeia(2015 edition), Notes to Medical Professions(Yi Zong Shuo Yue), and other medicine books were accessed to summarize the processing methods and decoction dosage of Aconiti Lateralis Radix Praeparata in both ancient and modern medicine, and in consideration of technical research and practice operation, Li Shizhen's description of Aconiti Lateralis Radix Praeparata and Professor Jin Shiyuan's research on Aconiti Lateralis Radix Praeparata dispensing technology were analyzed and collected. Li Shizhen recorded the nature identification and clinical application of Aconiti Lateralis Radix Praeparata by using pharmacological method state theory in Compendium of Materia Medica. National physician master Jin Shiyuan carries forward the essence of Li Shizhen's pharmaceutical academic thought with his own proficient knowledge structure in medicine, providing scientific pharmaceutical service for clinical application of Aconiti Lateralis Radix Praeparata Professor. Jin Shiyuan put forward the dispensing technology for the first time, including nature identification technology, clinical processing technology, clinical decocting technology, prescription coping technology, and class specifications of Aconiti Lateralis Radix Praeparata.

The purpose of this study was to examine the mentality of Chinese teachers regarding their use of humour in coping with stress. Specifically, the study investigated their frequency of use of humour in coping with stress as compared to other coping styles and their perceptions about the relationship of humour with other coping styles. Data were collected from a sample of 789 Chinese teachers holding teaching posts at local Hong Kong secondary schools. Based on responses made to the COPE questionnaire, there was evidence that Chinese teachers had a lower frequency of use of humour as compared to other coping styles. As suggested by the results of a factor analysis, there was a perception among Chinese teachers that the use of humour was related more closely to escaping and/or avoidance as coping strategies, but more differentiable from problem-focused/task-oriented and emotional/social coping. It is interesting to find that the results of our study echoed those of a previous crosscultural comparison between Chinese and Canadian university students, in which the Chinese university students reported less use of humour in coping with stress than did their Canadian counterparts. These results have provided some empirical support for the notion that "humor has been traditionally given little respect in Chinese culture mainly due to the Confucian emphasis on keeping proper manners in social interactions" (Yue, 2010, p. 403). As teachers in Chinese societies are regarded as persons who are full of wisdom and capable of problem-solving, it is expected that they should act as role models to their students. These social expectations on Chinese teachers could further mould their perceptions on the use of humour in coping with stress.

The integration of body-worn sensors with mobile devices presents a tremendous opportunity to improve just-in-time behavioral interventions by enhancing bidirectional communication between investigators and their participants. This approach can be used to deliver supportive feedback at critical moments to optimize the attainment of health behavior goals. The goals of this systematic review were to summarize data on the content characteristics of feedback messaging used in diet and physical activity (PA) interventions and to develop a practical framework for designing just-in-time feedback for behavioral interventions. Interventions that included just-in-time feedback on PA, sedentary behavior, or dietary intake were eligible for inclusion. Feedback content and efficacy data were synthesized descriptively. The review included 31 studies (15/31, 48%, targeting PA or sedentary behavior only; 13/31, 42%, targeting diet and PA; and 3/31, 10%, targeting diet only). All studies used just-in-time feedback, 30 (97%, 30/31) used personalized feedback, and 24 (78%, 24/31) used goal-oriented feedback, but only 5 (16%, 5/31) used actionable feedback. Of the 9 studies that tested the efficacy of providing feedback to promote behavior change, 4 reported significant improvements in health behavior. In 3 of these 4 studies, feedback was continuously available, goal-oriented, or actionable. Feedback that was continuously available, personalized, and actionable relative to a known behavioral objective was prominent in intervention studies with significant behavior change outcomes. Future research should determine whether all or some of these characteristics are needed to optimize the effect of feedback in just-in-time interventions. ©Susan M Schembre, Yue Liao, Michael C Robertson, Genevieve Fridlund Dunton, Jacqueline Kerr, Meghan E Haffey, Taylor Burnett, Karen Basen-Engquist, Rachel S Hicklen.

Microbes constitute a vital part of the plant holobiont. They establish plant-microbe or microbe-microbe associations, forming a unique microbiota with each plant species and under different environmental conditions. These microbial communities have to adapt to diverse environmental conditions, such as geographical location, climate conditions and soil types, and are subjected to changes in their surrounding environment. Elevated ozone concentration is one of the most important aspects of global change, but its effect on microbial communities living on plant surfaces has barely been investigated. In the current study, we aimed at elucidating the potential effect of elevated ozone concentrations on the phyllosphere (aerial part of the plant) and rhizoplane (surface of the root) microbiota by adopting next-generation 16S rRNA amplicon sequencing. A standard japonica rice cultivar Nipponbare and an ozone-tolerant breeding line L81 (Nipponbare background) were pre-grown in a greenhouse for 10 weeks and then exposed to ozone at 85 ppb for 7 h daily for 30 days in open top chambers. Microbial cells were collected from the phyllosphere and rhizoplane separately. The treatment or different genotypes did not affect various diversity indices. On the other hand, the relative abundance of some bacterial taxa were significantly affected in the rhizoplane community of ozone-treated plants. A significant effect of ozone was detected by homogeneity of molecular variance analysis in the phyllosphere, meaning that the community from ozone-treated phyllosphere samples was more variable than those from control plants. In addition, a weak treatment effect was observed by clustering samples based on the Yue and Clayton and weighted UniFrac distance matrices among samples. We therefore conclude that the elevated ozone concentrations affected the bacterial community structure of the phyllosphere and the rhizosplane as a whole, even though this effect was rather weak and did not lead to

The fourth member of the leucine-rich repeat-containing GPCR family (LGR4, frequently referred to as GPR48) and its cognate ligands, R-spondins (RSPOs) play crucial roles in the development of multiple organs as well as the survival of adult stem cells by activation of canonical Wnt signaling. Wnt/β-catenin signaling acts to regulate breast cancer; however, the molecular mechanisms determining its spatiotemporal regulation are largely unknown. In this study, we identified LGR4 as a master controller of Wnt/β-catenin signaling-mediated breast cancer tumorigenesis, metastasis, and cancer stem cell (CSC) maintenance. LGR4 expression in breast tumors correlated with poor prognosis. Either Lgr4 haploinsufficiency or mammary-specific deletion inhibited mouse mammary tumor virus (MMTV)- PyMT- and MMTV- Wnt1-driven mammary tumorigenesis and metastasis. Moreover, LGR4 down-regulation decreased in vitro migration and in vivo xenograft tumor growth and lung metastasis. Furthermore, Lgr4 deletion in MMTV- Wnt1 tumor cells or knockdown in human breast cancer cells decreased the number of functional CSCs by ∼90%. Canonical Wnt signaling was impaired in LGR4-deficient breast cancer cells, and LGR4 knockdown resulted in increased E-cadherin and decreased expression of N-cadherin and snail transcription factor -2 ( SNAI2) (also called SLUG), implicating LGR4 in regulation of epithelial-mesenchymal transition. Our findings support a crucial role of the Wnt signaling component LGR4 in breast cancer initiation, metastasis, and breast CSCs.-Yue, Z., Yuan, Z., Zeng, L., Wang, Y., Lai, L., Li, J., Sun, P., Xue, X., Qi, J., Yang, Z., Zheng, Y., Fang, Y., Li, D., Siwko, S., Li, Y., Luo, J., Liu, M.

In outcome studies of oncology patients undergoing radiation, researchers extract valuable information from medical records generated before, during, and after radiotherapy visits, such as survival data, toxicities, and complications. Clinical studies rely heavily on these data to correlate the treatment regimen with the prognosis to develop evidence-based radiation therapy paradigms. These data are available mainly in forms of narrative texts or table formats with heterogeneous vocabularies. Manual extraction of the related information from these data can be time consuming and labor intensive, which is not ideal for large studies. The objective of this study was to adapt the interactive information extraction platform Information and Data Extraction using Adaptive Learning (IDEAL-X) to extract treatment and prognosis data for patients with locally advanced or inoperable non-small cell lung cancer (NSCLC). We transformed patient treatment and prognosis documents into normalized structured forms using the IDEAL-X system for easy data navigation. The adaptive learning and user-customized controlled toxicity vocabularies were applied to extract categorized treatment and prognosis data, so as to generate structured output. In total, we extracted data from 261 treatment and prognosis documents relating to 50 patients, with overall precision and recall more than 93% and 83%, respectively. For toxicity information extractions, which are important to study patient posttreatment side effects and quality of life, the precision and recall achieved 95.7% and 94.5% respectively. The IDEAL-X system is capable of extracting study data regarding NSCLC chemoradiation patients with significant accuracy and effectiveness, and therefore can be used in large-scale radiotherapy clinical data studies. ©Shuai Zheng, Salma K Jabbour, Shannon E O'Reilly, James J Lu, Lihua Dong, Lijuan Ding, Ying Xiao, Ning Yue, Fusheng Wang, Wei Zou.

Dreaming woman: Image, place, and the aesthetics of exile.

Greenspan, Rachel

2017-08-01

Looking closely at an Argentine dream interpretation column published in a popular women's magazine from 1948 to 1951, this article examines the role of the dream image in shaping psychoanalytic discourse on femininity and national identity. The column, 'Psychoanalysis Will Help You,' emerged during Juan Domingo Perón's first presidency, featuring verbal interpretations written under the pen name 'Richard Rest,' as well as surreal photomontages by Grete Stern, a German-born, Bauhaus-trained photographer living in exile since 1936. While the column's Jungian text encourages readers' adaptation to the external reality of their social situation, Stern's droll images emphasize the disjuncture between subject and environment, exposing tensions between the experience of exile and the Peronist mission to consolidate an Argentine national identity. Experimenting formally with European avant-garde techniques, Stern presents femininity and nation as conflictive imaginary configurations. This theme resurfaces at the 2013 Venice Biennale, where Nicola Costantino's multimedia installation Eva - Argentina: A Contemporary Metaphor was exhibited alongside Carl Jung's Red Book. Formal contrasts between Stern's use of photomontage, Costantino's projection technique, and Jung's theory of mandala symbolism indicate the divergent ways in which their artwork posits the therapeutic function of the dream image, as well as the role of aesthetic production in psychoanalytic care.

The SuperB asymmetric e+e- collider and detector to be built at the newly founded Nicola Cabibbo Lab will provide a uniquely sensitive probe of New Physics in the flavor sector of the Standard Model. Studying minute effects in the heavy quark and heavy lepton sectors requires a data sample of 75 ab-1 and a peak luminosity of 1036 cm-2 s-1. The SuperB Computing group is working on developing a simulation production framework capable to satisfy the experiment needs. It provides access to distributed resources in order to support both the detector design definition and its performance evaluation studies. During last year the framework has evolved from the point of view of job workflow, Grid services interfaces and technologies adoption. A complete code refactoring and sub-component language porting now permits the framework to sustain distributed production involving resources from two continents and Grid Flavors. In this paper we will report a complete description of the production system status of the art, its evolution and its integration with Grid services; in particular, we will focus on the utilization of new Grid component features as in LB and WMS version 3. Results from the last official SuperB production cycle will be reported.

Thirty-three Landsat TM scenes of California stratocumulus cloud fields were acquired as part of the FIRE Marine Stratocumulus Intensive Field Observations in July 1987. They exhibit a wide variety of stratocumulus structures. Analysis has so far focused upon the July 7 scene, in which aircraft from NASA, NCAR, and the British Meteorological Office repeatedly gathered data across a stratocumulus-fair weather cumulus transition. The aircraft soundings validate the cloud base temperature threshold determined by spatial coherence analysis of the TM thermal band. Brightness variations in the stratocumulus region exhibit a -5/3 power-law decrease of the wavenumber spectra for scales larger than the cloud thickness, about 200 m, changing to a -3 power at smaller scales. Observations by an upward-looking three-channel microwave radiometer on San Nicolas Island also show the -5/3 power-law in total integrated liquid water, suggesting that the largest-scale TM brightness variations are primarily due to variations in the liquid water. The Kolmogorov 5/3 power suggests that for some purposes liquid water in turbulent stratocumulus clouds may be treated as a passive scalar, simply reflecting variations in vertical velocity. This may be tested using the velocities measured by the aircraft.

The First ISCCP Regional Experiment (FIRE) objective of validating and improving satellite algorithms for inferring cloud properties from satellite radiances was one of the central motivating factors in the design of the specific field experimental strategies used in the July, 1987 marine stratocumulus intensive field observations (IFO). The in situ measuring platforms were deployed to take maximum advantage of redundant measurements (for intercomparison of the in situ sensors) and to provide optimal coverage within satellite images. One of the most ambitious of these strategies was the attempt to coordinate measurements from San Nicolas Island (SNI), the R/V Pt. Sur, the meteorological aircraft, and the satellites. For the most part, this attempt was frustrated by flight restrictions in the vicinity of SNI. The exception was the mission of July 16, 1987, which achieved remarkable success in the coordination of the platforms. This presentation concerns operations conducted by the National Center for Atmospheric Research (NCAR) Electra and how data from the Electra can be integrated with and compared to data from the Pt. Sur, SNI, and the satellites. The focus is on the large-scale, integrated picture of the conditions on July 16 from the perspective of the Electra's flight operations.

Asthma is a heterogeneous disease comprising several phenotypes driven by different pathways. To define these phenotypes or endotypes (phenotypes defined by mechanisms), an unbiased approach to clustering of various omics platforms will yield molecular phenotypes from which composite biomarkers can be obtained. Biomarkers can help differentiate between these phenotypes and pinpoint patients suitable for specific targeted therapies - the basis for personalised medicine. Biomarkers need to be linked to point-of-care biomarkers that may be measured readily in exhaled breath, blood or urine. The potential for using mobile healthcare approaches will help patient enpowerment, an essential tool for personalised medicine. Personalised medicine in asthma is not far off - it is already here, but we need more tools and implements to carry it out for the benefit of our patients. Copyright ©ERS 2017.

The painting materials of the Portrait of Nicolaes van Bambeeck (Royal Museums of Fine Arts of Belgium, Brussels, inv. 155) painted by Rembrandt van Rijn in 1641 has been studied using high resolution cluster-TOF-SIMS imaging. In the first step, a moderate spatial resolution (2 μm) was used to characterize the layer structure and the chemical composition of each layer on account of a high mass resolution. Then, in the second step, and despite a low mass resolution, the cluster primary ion beam was focused well below 1 μm in order to reveal smaller structures in the painting sample. The study confirmed the presence of starch in the second ground layer, which is quite surprising and, at least for Rembrandt paintings, has never been reported before. TOF-SIMS also indicated the presence of proteins, which, added to the size and shape of lake particles, suggests that it was manufactured from shearings (waste of textile manufacturing) of dyed wool, used as the source of the dyestuff. The analyses have also shown various lead carboxylates, being the products of the interaction between lead white and the oil of the binding medium. These findings considerably contribute to the understanding of Rembrandt's studio practice and thus demonstrate the importance and potential of cluster-TOF-SIMS imaging in the characterization on a submicrometer scale of artist painting materials.

Mexico's peasant sector is undergoing great change as a result of the insertion of capitalist relations into areas that were previously remote. The traditional peasant subsistence economy has been displaced, and peasants have been forced to adopt a series of new strategies for survival, entailing proletarianization or selling of labor. Women in the community of San Nicolas Zoyapetlayoca, in the municipio of Tepeaca, have lived in a situation of poverty and precariousness for some time. Most of the population historically depended on the neighboring haciendas for their livelihood. Women and children also worked there, mistreated and without social protection. The lands that were distributed after the Revolution are insufficient to support the community, and most families must look elsewhere for employment. Incomes are insufficient to cover all the necessities of education, health, nutrition, and other aspects of life. Most women are educated no farther than the primary level. They spend most of their time preparing food, carrying water, washing clothes, caring for their children, and in other domestic chores. Some women work for wages as laborers, factory workers, or domestics. Rural women are disadvantaged by poor working conditions, insufficient education, low levels of health and nutrition, limited participation in social and political life, poor housing and lack of services, and frequently by their own attitudes of traditionalism or fatalism.

Here, we present a design study on a 16x zoom lens with 4 groups (including two internal moving groups), designed for, but not limited to, a visible spectrum surveillance camera. Fifteen different solutions were discovered with nearly diffraction limited performance, using PNPX or PNNP design forms with the stop located in either the third or fourth group. Some interesting patterns and trends in the summarized results include the following: (a) in designs with such a large zoom ratio, the potential of locating the aperture stop in the front half of the system is limited, with ray height variations through zoom necessitating a very large lens diameter; (b) in many cases, the lens zoom motion has significant freedom to vary due to near zero total power in the middle two groups; and (c) we discuss the trade-offs between zoom configuration, stop location, packaging factors, and zoom group aberration sensitivity.

Effects of experimental overgrowth on survival and change in the turf assemblage of a giant kelp forest

Crustose coralline algae were the prevalent cover among sessile organisms that paved or grew near the substratum, and also the most commonly overgrown species in a giant kelp Macrocystis pyrifera (L.) C.A. Agardh forest located off San Nicolas Island, California. Giant kelp was the largest and most conspicuous species that overgrew large patches of the substrata; overgrowth among turf organisms also appeared common. To determine the effects of giant kelp holdfasts on crustose coralline algae and other turf organisms,'artificial holdfasts' were placed on 0.125-m2 plots for 5, 8 and 12 months. In these treatments, 50?57% of the crustose coralline algae survived. Because these algae also recruited while covered, the total cover (survivorship plus recruitment) differed by only 7?26% from that sampled at the start of the study. The decline of these algae in control plots was similar to that in the treatment plots mostly because of overgrowth by sessile invertebrates. Bryozoans increased markedly on the control plots, whereas 0?12% survived in the treatment plots. Bryozoans and sponges also recruited under the artificial holdfasts. Some arborescent turf algae survived in the 5- and 8-month treatments; articulated coralline algae survived better than did foliose algae. High survival recruitment of crustose coralline algae while overgrown contributed to their prevalence in benthic communities.

On the fundamental relation of laser schlieren deflectometry for temperature measurements in filamentary plasmas

Recently, laser schlieren deflectometry (LSD) had been successfully employed as a temperature measurement method to reveal the heat convection generated by micro filaments of a self-organized non-thermal atmospheric plasma jet. Based on the theory of the temperature measurements using LSD, in this work, three approaches for an application of the method are introduced: (i) a hyperbolic-like model of refractive index is applied which allows an analytical theory for the evaluation of the deflection angle to be developed, (ii) a Gaussian shape model for the filament temperature is implemented which is analyzed numerically and (iii) an experimental calibration of the laser deflection with a gas mixture of helium and argon is performed. Thus, these approaches demonstrate that a universal relation between the relative maximum temperature of the filament core (T1/T0) and a the maximum deflection angle δ1 of the laser beam can be written as T1/T0=(1 - δ1/δ0)-1, where δ0 is a parameter that is defined by the configuration of the experiment and by the assumed model for the shape of the temperature profile.

In this study, a personalization method (Guida, Tardieu, & Nicolas, European Journal of Cognitive Psychology, 21: 862-896 2009) was applied to a free-recall task. Fifteen pairs of words, composed of an object and a location, were presented to 93 participants, who had to mentally associate each pair and subsequently recall the objects. A 30-s delay was introduced on half of the trials, the presentation rate was manipulated (5 or 10 s per item), and verbal and visuospatial working memory tests were administered to test for their effects on the serial curve. Two groups were constituted: a personalized group, for whom the locations were well-known places on their university campus, and a nonpersonalized group, for whom the locations did not refer to known places. Since personalization putatively operationalizes long-term working memory (Ericsson & Kintsch, Psychological Review, 102: 211-245 1995)-namely, the capacity to store information reliably and rapidly in long-term memory-and if we take a dual-store approach to memory, the personalization advantage would be expected to be greater for pre-recency than for recency items. Overall, the results were compatible with long-term working memory theory. They contribute to validating the personalization method as a methodology to characterize the contribution of long-term memory storage to performance in working memory tasks.

The 'royal disease'--haemophilia A or B? A haematological mystery is finally solved.

  'History can change blood. And blood can change the course of history'. Haemophilia is an illustration of this, as this congenital hereditary coagulation disorder, passed through the majority of royal European families at the beginning of the 20th century by Queen Victoria of England and Empress of the Indies, had indisputable political consequences, which led to one of the most defining moments of contemporary history: the Bolshevik Revolution. Today, none of Queen Victoria's living descendents carry haemophilia. Because of this, the characterization of haemophilia (deficit of either factor VIII or XI) and the identification of the causal mutation are rendered impossible. In 1991, a tomb containing the remains of Czar Nicolas II's entire family was discovered. A second tomb was discovered in 2007, allowing Russian and American scientists to fill in this gap in medical history. Following a scientific approach combining current genetic experimentation tools and the development of biological information technology, researchers were able to identify each body, allowing them to obtain precious genetic material from the young Czar Alexis, who was stricken by the disease, which revealed a causal substitution in the splice acceptor site of exon 4 in the F9 gene. This mutation that is responsible for haemophilia B had traumatized European royal families throughout the 20th century! © 2010 Blackwell Publishing Ltd.

Three models for nonlocal electron thermal transport are here compared against Vlasov-Fokker-Planck (VFP) codes to assess their accuracy in situations relevant to both inertial fusion hohlraums and tokamak scrape-off layers. The models tested are (i) a moment-based approach using an eigenvector integral closure (EIC) originally developed by Ji, Held, and Sovinec [Phys. Plasmas 16, 022312 (2009)]; (ii) the non-Fourier Landau-fluid (NFLF) model of Dimits, Joseph, and Umansky [Phys. Plasmas 21, 055907 (2014)]; and (iii) Schurtz, Nicolaï, and Busquet’s [Phys. Plasmas 7, 4238 (2000)] multigroup diffusion model (SNB). We find that while the EIC and NFLF models accurately predict the dampingmore » rate of a small-amplitude temperature perturbation (within 10% at moderate collisionalities), they overestimate the peak heat flow by as much as 35% and do not predict preheat in the more relevant case where there is a large temperature difference. The SNB model, however, agrees better with VFP results for the latter problem if care is taken with the definition of the mean free path. Additionally, we present for the first time a comparison of the SNB model against a VFP code for a hohlraum-relevant problem with inhomogeneous ionisation and show that the model overestimates the heat flow in the helium gas-fill by a factor of ~2 despite predicting the peak heat flux to within 16%.« less

studies, confirmed the presence of more extensive aureoles than shown in published geologic maps; few misclassified areas were noted. Additional plowed fields consisting of exposed contact metamorphic soil were mapped digitally in an August 1985 TM scene. Subsequently, this approach was used to map two 1-km-wide linear zones of contact metamorphosed rock and oil in the San Nicolas-Sn-W Mine area, which is located approximated 125 km southeast of the Caceras study area. Exposures of granite in the San Nicolas area are limited to a few unaltered granitic dikes in the mine and a small exposure of unaltered pegmatite-bearing granite in a quarry about 1.5 km west of the mine. The present of coarsely crystalline biotite and beryl in the granite in the quarry and of contact metamorphosed slate up to 2.5 km from the nearest granite exposure suggest that only the apical part of a pluton is exposed in the quarry and that a larger, shallowly buried body is probably present. These results indicate that potential application of TM image analysis to mineral exploration in lithologically similar areas that are cultivated in spite of poor rock exposures.

The Possible Decapitation of a Megathrust Indenter: Evidence from Imaging of Time-dependent Microseismic Structures before and after the 2012 Mw 7.6 Nicoya, Costa Rica

We normally view the subduction megathrust surface as a constant structure throughout the seismic cycle, with the elastic loading, microseismicity, and slip occurring along it. However, using small events recorded from a uniquely dense seismic network directly over the active megathrust below Nicoya, Costa Rica, we find two different seismogenic structures with near exclusive time-dependent behavior immediately in the region of maximum coseismic slip. Microseismicity recorded at intervals between 1999 and 2009 showed an elevated topographic indenter beneath central Nicoya, and associated with a suture marking transition between Cocos-Nazca Spreading Center and East-Pacific Rise crusts [Kyriakopoulos et al., JGR 2015]. This indenter is located as a focus of interseismic locking and coseismic rupture [Feng et al., JGR 2012; Yue et al., JGR 2013; Protti et al., Nat. Geosc. 2014; Xue et al., JGR 2015; Kyriakopoulos & Newman, JGR 2016]. However, aftershocks recorded in the months following an MW 7.6 earthquake in 2012 define an entirely different structure about 5 km deeper and differing only in the area of maximum coseismic slip. The location of seismicity switches entirely between these faults from the shallow indenter structure beforehand to the deeper and near-linear feature after. To improve our imaging of the behavior and associated slab structure, we perform a detailed joint seismic relocation and tomographic inversion using TomoDD [Zhang and Thurber, PAGEOPH 2003]. We analyze the new locations relative to the imaged slab geometry, and compare automated formulations of the interfaces using the Maximum Seismicity Method [Kyriakopoulos et al., 2015], with data existing before and after the earthquake. Lastly, we show the sensitivity of using either surface in models for fault slip from regional GPS. We hypothesize that the bifurcated fault structure signifies either active decapitation of the indenter, possibly along the crust-mantle interface of the downgoing slab

Refinements on the inferred causative faults of the great 2012 Indian Ocean earthquakes

As the largest known intra-plate strike-slip events, the pair of 2012 earthquakes in the Wharton Basin is a rarity. Separated in time by 2 hours these events rouse interest also because of their short inter-event duration, complex rupture mechanism, and spatial-temporal proximity to the great 2004 Sumatra plate boundary earthquake. Reactivation of fossil ridge-transform pairs is a favoured mechanism for large oceanic plate earthquakes and their inherent geometry triggers earthquakes on conjugate fault systems, as observed previously in the Wharton Basin. The current debate is whether the ruptures occurred on the WNW-ESE paleo ridges or the NNE-SSW paleo transforms. Back-projection models give a complex rupture pattern that favours the WNW-ESE fault [1]. However, the static stress changes due to the 2004 Sumatra earthquake and 2005 Nias earthquake favour the N15°E fault [2]. We use the Teleseismic Body-Wave Inversion Program [3] and waveform data from Global Seismic Network, to obtain the best fit solutions using P and S-wave synthetic modelling. The preliminary P-wave analysis of both earthquakes gives source parameters that are consistent with the Harvard CMT solutions. The obtained slip distribution complies with the NNE-SSW transforms. Both these earthquakes triggered small tsunamis which appear as two distinctive pulses on 13 Indian Ocean tide gauges and buoys. Frequency spectra of the tsunami recordings from various azimuths provide additional constraint for the choice of the causative faults. References: [1] Yue, H., T. Lay, and K. D.

Microbes constitute a vital part of the plant holobiont. They establish plant-microbe or microbe-microbe associations, forming a unique microbiota with each plant species and under different environmental conditions. These microbial communities have to adapt to diverse environmental conditions, such as geographical location, climate conditions and soil types, and are subjected to changes in their surrounding environment. Elevated ozone concentration is one of the most important aspects of global change, but its effect on microbial communities living on plant surfaces has barely been investigated. In the current study, we aimed at elucidating the potential effect of elevated ozone concentrations on the phyllosphere (aerial part of the plant) and rhizoplane (surface of the root) microbiota by adopting next-generation 16S rRNA amplicon sequencing. A standard japonica rice cultivar Nipponbare and an ozone-tolerant breeding line L81 (Nipponbare background) were pre-grown in a greenhouse for 10 weeks and then exposed to ozone at 85 ppb for 7 h daily for 30 days in open top chambers. Microbial cells were collected from the phyllosphere and rhizoplane separately. The treatment or different genotypes did not affect various diversity indices. On the other hand, the relative abundance of some bacterial taxa were significantly affected in the rhizoplane community of ozone-treated plants. A significant effect of ozone was detected by homogeneity of molecular variance analysis in the phyllosphere, meaning that the community from ozone-treated phyllosphere samples was more variable than those from control plants. In addition, a weak treatment effect was observed by clustering samples based on the Yue and Clayton and weighted UniFrac distance matrices among samples. We therefore conclude that the elevated ozone concentrations affected the bacterial community structure of the phyllosphere and the rhizosplane as a whole, even though this effect was rather weak and did not lead to

Background: Since the serotonin (5-HT) is associated with circadian rhythm and breathing regulation, the serotonin transporter (5-HTT), which plays an important role in serotoninergic transmission, might be a strong candidate gene in the pathogenesis of obstructive sleep apnea syndrome (OSAS). Objective: To investigate the association of 5-HTT gene polymorphisms with OSAS and clinical characteristics. Methods: We genotyped the 5-HTT gene linked polymorphic region (5-HTTLPR) and a variable number of tandem repeats at intron 2 (STin2.VNTR) in 254 OSAS patients and 338 healthy controls in Chinese Han population. Results: In total sample, the 10-repeat allele of STin2.VNTR was significantly associated with OSAS (P = 0.007, OR = 1.72, 95% CI = 1.15~2.58), but no association was found in 5-HTTLPR. In male subjects, both polymorphisms showed significant association with OSAS (Allele L: P = 0.005, OR = 1.44, 95% CI = 1.11 to 1.87; Allele 10: P = 0.002, OR = 1.94, 95% CI = 1.26 to 3.00). Two haplotypes, S-12 and L-10, constructed by the above polymorphisms also revealed significant associations with OSAS (global P-values were 0.020 for total sample and 0.0006 for male subjects, respectively). Male patients carrying the haplotype S-12 showed a significantly lower apnea / hypopnea index (AHI), depressive factor, plasma 5-HT level and 5-hydroxyindolacetic acid (5-HIAA) levels, but higher episodic memory, when compared with non-S-12 carriers (P < 0.05). However, no significant differences were found in excessive daytime sleepiness or other psychological function across haplotype carriers (P > 0.05). Conclusions: These findings support that 5-HTT gene may be involved in susceptibility to OSAS, especially with sex-dependent effect.

This work aims at presenting the scientific results stemming from six Short-Term Scientific Missions (STSMs) funded by the COST (European COoperation in Science and Technology) Action TU1208 'Civil Engineering Applications of Ground Penetrating Radar' (Action Chair: Lara Pajewski, STSM Manager: Marian Marciniak). STSMs are important means to develop linkages and scientific collaborations between participating institutions involved in a COST Action. Scientists have the possibility to go to an institution abroad, in order to undertake joint research and share techniques/equipment/infrastructures that may not be available in their own institution. STSMs are particularly intended for Early Stage Researchers (ESRs), i.e., young scientists who obtained their PhD since no more than 8 years when they started to be involved in the Action. Duration of a standard STSM can be from 5 to 90 days and the research activities carried out during this short stay shall specifically contribute to the achievement of the scientific objectives of the supporting COST Action. The first STSM was carried out by Lara Pajewski, visiting Antonis Giannopoulos at The University of Edinburgh (United Kingdom). The research activities focused on the electromagnetic modelling of Ground Penetrating Radar (GPR) responses to complex targets. A set of test scenarios was defined, to be used by research groups participating to Working Group 3 of COST Action TU1208, to test and compare different electromagnetic forward- and inverse-scattering methods; these scenarios were modelled by using the well-known finite-difference time-domain simulator GprMax. New Matlab procedures for the processing and visualization of GprMax output data were developed. During the second STSM, Iraklis Giannakis visited Lara Pajewski at Roma Tre University (Italy). The study was concerned with the numerical modelling of horn antennas for GPR. An air-coupled horn antenna was implemented in GprMax and tested in a realistically

For more than three decades healthcare decentralization has been promoted in developing countries as a way of improving the financing and delivery of public healthcare. Decision autonomy under healthcare decentralization would determine the role and scope of responsibility of local authorities. Jalal Mohammed, Nicola North, and Toni Ashton analyze decision autonomy within decentralized services in Fiji. They conclude that the narrow decision space allowed to local entities might have limited the benefits of decentralization on users and providers. To discuss the costs and benefits of healthcare decentralization this paper uses the U-form and M-form typology to further illustrate the role of decision autonomy under healthcare decentralization. This paper argues that when evaluating healthcare decentralization, it is important to determine whether the benefits from decentralization are greater than its costs. The U-form and M-form framework is proposed as a useful typology to evaluate different types of institutional arrangements under healthcare decentralization. Under this model, the more decentralized organizational form (M-form) is superior if the benefits from flexibility exceed the costs of duplication and the more centralized organizational form (U-form) is superior if the savings from economies of scale outweigh the costly decision-making process from the center to the regions. Budgetary and financial autonomy and effective mechanisms to maintain local governments accountable for their spending behavior are key decision autonomy variables that could sway the cost-benefit analysis of healthcare decentralization. © 2016 by Kerman University of Medical Sciences.

Identification of biogeochemical reactions in aquifers and determining kinetics is important for the prediction of contaminant transport in aquifers and groundwater management. Therefore, experiments accounting for both conservative and reactive transport are essential to understand the biogeochemical reactivity at field scale. This study presents the results of a groundwater tracer test using the combined injection of dissolved conservative and reactive tracers (He, Xe, Ar, Br-, O2 and NO3-) in order to evaluate the transport properties of a fractured media in Brittany, France. Dissolved gas concentrations were continuously monitored in situ with a CF-MIMS (Chatton et al, 2016) allowing a high frequency (1 gas every 2 seconds) multi-tracer analysis (N2, O2, CO2, CH4, N2O, H2, He, Ne, Ar, Kr, Xe) over a large resolution (6 orders of magnitude). Along with dissolved gases, groundwater biogeochemistry was monitored through the sampling of major anions and cations, trace elements and microbiological diversity. The results show breakthrough curves allowing the combined quantification of conservative and reactive transport properties. This ongoing work is an original approach investigating the link between heterogeneity of porous media and biogeochemical reactions at field scale.

We sampled a front detected by SST gradient, ocean color imagery, and a Spray glider south of San Nicolas Island in the Southern California Bight between 14 and 18 October 2010. We sampled the front with an unusually extensive array of instrumentation, including the Continuous Underway Fish Egg Sampler (CUFES), the undulating In Situ Ichthyoplankton Imaging System (ISIIS) (fitted with temperature, salinity, oxygen, and fluorescence sensors), multifrequency acoustics, a surface pelagic trawl, a bongo net, and a neuston net. We found higher fluorescence and greater cladoceran, decapod, and euphausiid densities in the front, indicating increased primary and secondary production. Mesopelagic fish were most abundant in oceanic waters to the west of the front, market squid were abundant in the front associated with higher krill and decapod densities, and jack mackerel were most common in the front and on the shoreward side of the front. Egg densities peaked to either side of the front, consistent with both offshore (for oceanic squid and mesopelagic fish) and shelf origins (for white croaker and California halibut). We discovered unusually high concentrations of predatory narcomedusae in the surface layer of the frontal zone. Potential ichthyoplankton predators were more abundant either in the front (decapods, euphausiids, and squid) or shoreward of the front (medusae, chaetognaths, and jack mackerel). For pelagic fish like sardine, which can thrive in less productive waters, the safest place to spawn would be offshore because there are fewer potential predators.

Laying the Foundations of Contemporary Romanian Astronomy

Marin, Sorin

2017-11-01

This article describes the first stage in the history of Romanian astronomy represented by the events, processes and evolution which led to the formation of great scientific personalities, development drives and the creation of the material base for the contemporary Romanian astronomy, having a focus point on the activity of Bucharest Observatory. The article discusses the roots of an evolution pathway determined and inspired by the activity of several scientific personalities of Romania such as Stefan Hepites, Spiru Haret, Nicolae Coculescu and others. It also underlines that a great importance for the astronomical research in Romania was given by the outstanding technical value of the main instruments used at the Observatory in the first decades of activity and, consequentially, by their longevity in service: in the Equatorial Dome - the impressive 6 m. Prin-Mertz telescope and in the Meridian Hall - the GautierPrin telescope. This determined the formation of a powerful astrometry division and a research drive which led over time to important scientific works such as the ultraprecise stellar catalogues developed in Romania at Bucharest Observatory, which were appreciated and awarded nationally and internationally. Therefore, the article includes the moments and the people which determined the success of laying the foundations of the Observatory in 1908 and then having completed the initial scientific infrastructure in 1912 when the construction work was finished, and briefly presents the features, scientific utilisation and outputs of its telescopes, some of the best in the world in their golden years.

Reduced disease in black abalone following mass mortality: phage therapy and natural selection

Black abalone, Haliotis cracherodii, populations along the NE Pacific ocean have declined due to the rickettsial disease withering syndrome (WS). Natural recovery on San Nicolas Island (SNI) of Southern California suggested the development of resistance in island populations. Experimental challenges in one treatment demonstrated that progeny of disease-selected black abalone from SNI survived better than did those from naïve black abalone from Carmel Point in mainland coastal central California. Unexpectedly, the presence of a newly observed bacteriophage infecting the WS rickettsia (WS-RLO) had strong effects on the survival of infected abalone. Specifically, presence of phage-infected RLO (RLOv) reduced the host response to infection, RLO infection loads, and associated mortality. These data suggest that the black abalone: WS-RLO relationship is evolving through dual host mechanisms of resistance to RLO infection in the digestive gland via tolerance to infection in the primary target tissue (the post-esophagus) coupled with reduced pathogenicity of the WS-RLO by phage infection, which effectively reduces the infection load in the primary target tissue by half. Sea surface temperature patterns off southern California, associated with a recent hiatus in global-scale ocean warming, do not appear to be a sufficient explanation for survival patterns in SNI black abalone.

Black abalone, Haliotis cracherodii, populations along the NE Pacific ocean have declined due to the rickettsial disease withering syndrome (WS). Natural recovery on San Nicolas Island (SNI) of Southern California suggested the development of resistance in island populations. Experimental challenges in one treatment demonstrated that progeny of disease-selected black abalone from SNI survived better than did those from naïve black abalone from Carmel Point in mainland coastal central California.

the lifestyles of people with myotonic dystrophy type 1 (DM1) are poorly understood and yet their consideration is essential for effective long-term care. The nursing care provided in the reference centers integrates the diversity clinic of this disease in interdisciplinary care, but it is more complicated from a relational point of view. The objective of this qualitative study was to understand the ways of living for a person with DM1, his body and the coping strategies developed. this research in social sciences and nursing is based on a problem of care and is based on an ethnosociological problematization. the aim is to make visible the evolution of the body affected by Steinert’s disease, participating in the construction of the body pattern and the social identity of the person, which allows him to maintain himself in a “normal” daily life as long as possible but can reach limits imposing him radical reorientations in his life. These results are discussed in the light of a framework of analysis based on the four levels of reading of the body proposed by Nicolas Vonarx: the “material body” ; the “capable body”, the “body feeling” and the “knowing/judging body” ; “socializing body” will be proposed to discuss the place the body takes for people living with a DM1 when it comes to living within a normative society.

As cancer survival rates increase, the challenge of ensuring that cancer survivors reclaim their quality of life (QoL) becomes more important. This paper outlines the research element of a research and training program that is designed to do just that. Bridging sectors, disciplines, and geographies, it brings together eight PhD projects and students from across Europe to identify the underlying barriers, test different technology-enabled rehabilitative approaches, propose a model to optimize the patient pathways, and examine the business models that might underpin a sustainable approach to cancer survivor reintegration using technology. The program, funded under the European Union's Horizon 2020 research and innovation program under the Marie Sklodowska-Curie grant agreement No 722012, includes deep disciplinary PhD projects, intersectoral and international secondments, interdisciplinary plenary training schools, and virtual subject-specific education modules. The 8 students have now been recruited and are at the early stages of their projects. CATCH will provide a comprehensive training and research program by embracing all key elements-technical, social, and economic sciences-required to produce researchers and project outcomes that are capable of meeting existing and future needs in cancer rehabilitation. ©Nicola Mountford, Enrique Dorronzoro Zubiete, Threase Kessie, Begonya Garcia-Zapirain, Roberto Nuño-Solinís, David Coyle, Kristin B Munksgaard, Luis Fernandez-Luque, Octavio Rivera Romero, Matilde Mora Fernandez, Pedro Valero Jimenez, Ailish Daly, Ruth Whelan, Brian Caulfield.

In this study, we examined the prevalence, pathology, and epidemiology of tumors in free-ranging island foxes occurring on three islands in the California Channel Islands, USA. We found a remarkably high prevalence of ceruminous gland tumors in endangered foxes (Urocyon littoralis catalinae) occurring on Santa Catalina Island (SCA)—48.9% of the dead foxes examined from 2001–2008 had tumors in their ears, and tumors were found in 52.2% of randomly-selected mature (≥ 4 years) foxes captured in 2007–2008, representing one of the highest prevalences of tumors ever documented in a wildlife population. In contrast, no tumors were detected in foxes from San Nicolas Island or San Clemente Island, although ear mites (Otodectes cynotis), a predisposing factor for ceruminous gland tumors in dogs and cats, were highly prevalent on all three islands. On SCA, otitis externa secondary to ear mite infection was highly correlated with ceruminous gland hyperplasia (CGH), and tumors were significantly associated with the severity of CGH, ceruminous gland dysplasia, and age group (older foxes). We propose a conceptual model for the formation of ceruminous gland tumors in foxes on SCA that is based on persistent, ubiquitous infection with ear mites, and an innate, over exuberant inflammatory and hyperplastic response of SCA foxes to these mites. Foxes on SCA are now opportunistically treated with acaricides in an attempt to reduce mite infections and the morbidity and mortality associated with this highly prevalent tumor. PMID:26618759

Systemic amyloid A (AA) amyloidosis is highly prevalent (34%) in endangered island foxes (Urocyon littoralis) and poses a risk to species recovery. Although elevated serum amyloid A from prolonged or recurrent inflammation predisposes to AA amyloidosis, additional risk factors are poorly understood. Here we define the severity of glomerular and medullary renal amyloid and identify risk factors for AA amyloidosis in 321 island foxes necropsied from 1987 through 2010. In affected kidneys, amyloid more commonly accumulated in the medullary interstitium than in the glomeruli [98% (78/80) versus 56% (45/80), respectively, p < 0.0001], and medullary deposition was more commonly severe [19% (20/105)] as compared to glomeruli [7% (7/105), p = 0.01]. Univariate odds ratios (ORs) of severe renal AA amyloidosis were greater for short- and long-term captive foxes compared to free-ranging (OR=3.2, 3.7, respectively, overall p = 0.05) and females compared to males (OR = 2.9, p = 0.05). Multivariable logistic regression revealed independent risk factors for amyloid development were increasing age class (OR = 3.8, p < 0.0001), San Clemente Island subspecies compared to San Nicolas Island subspecies (OR = 5.3, p = 0.0003), captivity (OR = 5.1, p = 0.0001), and nephritis (OR = 2.3, p = 0.01). The increased risk associated with the San Clemente subspecies or captivity suggests roles for genetic as well as exogenous risk factors in the development of AA amyloidosis. PMID:26419399

In the article, there are errors in Table 7. The percentages of the attachment classifications do not add up to 100%. The corrected version of Table 7 is provided in the erratum. (The following abstract of the original article appeared in record 2015-55801-001.) Twenty years ago, meta-analytic results (k = 19) confirmed the association between caregiver attachment representations and child-caregiver attachment (Van IJzendoorn, 1995). A test of caregiver sensitivity as the mechanism behind this intergenerational transmission showed an intriguing "transmission gap." Since then, the intergenerational transmission of attachment and the transmission gap have been studied extensively, and now extend to diverse populations from all over the globe. Two decades later, the current review revisited the effect sizes of intergenerational transmission, the heterogeneity of the transmission effects, and the size of the transmission gap. Analyses were carried out with a total of 95 samples (total N = 4,819). All analyses confirmed intergenerational transmission of attachment, with larger effect sizes for secure-autonomous transmission (r = .31) than for unresolved transmission (r = .21), albeit with significantly smaller effect sizes than 2 decades earlier (r = .47 and r = .31, respectively). Effect sizes were moderated by risk status of the sample, biological relatedness of child-caregiver dyads, and age of the children. Multivariate moderator analyses showed that unpublished and more recent studies had smaller effect sizes than published and older studies. Path analyses showed that the transmission could not

Dimitrie Onciul 23e25, Sector 2, 024053 Bucharest, Romania Razelm-Sinoe Lagoon System, situated in the NW part of the Black Sea, in tight connection with the Danube Delta, has been subject to major changes due to human interventions in the past century. These changes have resulted into a complete change of the Lagoon specific ecosystems compared to its pristine state. In its natural state, as brackish - transitional environment, Antipa (1894) mentions Razelm Lagoon as one of the places with the greatest fisheries around the Black Sea coast (about 1879 - 1884, there were approximately 10,000 fishermen, all working on the Razelm Sinoe Lagoon System). Starting with the end of the XIXth Century, new canals were dug and existing channels were dredged in order to develop tighter connections with the Danube River. The natural inlet of Portita was blocked four decades ago and connections between the various parts of the lagoon system were controlled by the building of locks and sluices. The 2 inlets of Sinoe Lagoon were also controlled during early 1980s. Under these conditions, the lagoon ecosystem changed from brackish towards freshwater, with major effects on the existing flora and fauna. The period of brutal interventions ended in 1989 and the Razelm-Sinoe Lagoon System became part of the Danube Delta Biosphere Reserve in 1991, with a strict policy of nature protection and restoration. Spatial planning has been the major management option for the entire reserve, lagoon system included. Plans for sustainable development of the Razelm-Sinoe Lagoon System have been built in a participative manner, involving the local stakeholders, as part of FP7 ARCH project. Special attention has been given to impacts of climate change. The study presents the vision for the development Razelm-Sinoe Lagoon System over

Textural evolution of a dunitic matrix during formation of hybrid troctolites: insights from the Monte Maggiore peridotitic body (Corsica, France).

Many recent studies investigate the formation of hybrid troctolites after melt-rock interactions and impregnation of a dunitic matrix (Drouin et al, 2010; Sanfilippo et al, 2015). They describe the reactive percolation of a melt in a dunite, dissolving olivine and crystallizing interstitial minerals (plagioclase ± clinopyroxene), thus leading to the dismembering of mantle olivines and variations in the olivine crystal number, size and shape (Boudier & Nicolas, 1995). However, despite the number of studies describing a hybrid origin for troctolites, this process is rarely documented in a field-controlled geological setting allowing the observation of a gradient of the amount of melt impregnation in mantle dunites. The Monte Maggiore peridotitic body (Corsica, France) preserves a multi-stage melt-rock reaction decompressional evolution (Rampone et al, 2008), marked by a first episode of olivine-saturated melt percolation at spinel facies, which dissolved mantle pyroxenes and crystallized olivine, thus leading to the formation of replacive dunites. A second diffuse melt impregnation in the spinel peridotites and dunites dissolved olivine and crystallized interstitial plagioclase, orthopyroxene and clinopyroxene at plagioclase-facies conditions. This increasing modal proportion in interstitial phases led to the replacive formation of plagioclase peridotites, plagioclase dunites and hybrid troctolites. This makes the Monte Maggiore peridotites an ideal case study to investigate the formation of hybrid troctolites and the associated textural evolution of the rock-forming minerals by detailed field and microstructural observations. In order to quantify the evolution of the olivine matrix texture (i.e. number of grains, grain size, shape factor, aspect ratio) at thin section scale with ongoing melt impregnation, we used EBSD maps of 12 samples from spinel dunites to plagioclase dunites and troctolites. In these samples, reactive melt percolation and melt entrapment led to

In this early stage of the work we present a preliminary study of hydrothermal mineralizations found in Verzino locality, Crotone Basin, Southern Appennines, (Calabria, Italy). Both geochemical and petrographic investigations were developed with the aim of understanding the genesis of the sulfide-sulfate associations present in the "Argille Marnose del Ponda" formation, deepening their relationship with fluids circulation. These mineralizations have been recognized only in two "Calanchi" morphostructures - Badlands like morphology developed by the differential erosional pattern of the "Argille Marnose del Ponda" fm. - and constituting the northwestern flank of a little valley evolved in the Miocene sedimentary sequence from "Conglomerato di S.Nicola" fm. to "Evaporiti Superiori" fm. The mineralizations are distributed along isooriented centimetric veins (with mean direction of N120) and in nodules diffused close to the veins. These hydrothermal mineralizations are constituted by an associations of Pyrite spherical nodules (millimetric to centimetric in radius with occurrences of well developed octahedral habit single crystals), sulphate crystals (Gypsum, Jarosite, NatroJarosite), Oxides (Goethite mainly), millimetric veins of Barite and micrometric Ankerite specimens. The data (mineral habits, semiquantitative compositions and x-Ray spectra), obtained by an integration of S.E.M and XRD investigations, permit us, at the current stage of the study, to hypothesize a possible hydrothermal origin (whose temperature range estimate needs further investigations) for the sulfide-sulfate mineral phases. At the moment, we exclude their primary or secondary sedimentary provenance. The comparison of our results with the previous scientific literature focused on hydrothermal sulfide-sulfate systems (Vinogradov and Stephanov, 1964; Kostov, 1968; Plummer 1971; Boles, 1978; Ferrini and Moretti 1998) allows us to propose a possible "thermal window" ranging in the interval 50°C-230�

Move over, hot Jupiters theres an even stranger kind of giant planet in the universe! Ultra-hot Jupiters are so strongly irradiated that the molecules in their atmospheres split apart. What does this mean for heat transport on these planets?Atmospheres of Exotic PlanetsA diagram showing the orbit of an ultra-hot Jupiter and the longitudes at which dissociation and recombination occur. [Bell Cowan 2018]Similar to hot Jupiters, ultra-hot Jupiters are gas giants with atmospheres dominated by molecular hydrogen. What makes them interesting is that their dayside atmospheres are so hot that the molecules dissociate into individual hydrogen atoms more like the atmospheres of stars than planets.Because of the intense stellar irradiation, there is also an extreme temperature difference between the day and night sides of these planets potentially more than 1,000 K! As the stellar irradiation increases, the dayside atmosphere becomes hotter and hotter and the temperature difference between the day and night sides increases.When hot atomic hydrogen is transported into cooler regions (by winds, for instance), it recombines to form H2 molecules and heats the gas, effectively transporting heat from one location to another. This is similar to how the condensation of water redistributes heat in Earths atmosphere but what effect does this phenomenon have on the atmospheres of ultra-hot Jupiters?Maps of atmospheric temperature of molecular hydrogen dissociation fraction for three wind speeds.

This LETTER REPORT has been prepared by Idaho National Laboratory for US Navy NAVFAC EXWC to support in testing pre-commercial SIREN (Simulated Integration of Renewable Energy Networks) computer software models. In the logistics mode SIREN software simulates the combination of renewable power sources (solar arrays, wind turbines, and energy storage systems) in supplying an electrical demand. NAVFAC EXWC will create SIREN software logistics models of existing or planned renewable energy projects at five Navy locations (San Nicolas Island, AUTEC, New London, & China Lake), and INL will deliver additional HOMER computer models for comparative analysis. In the transient mode SIRENmore » simulates the short time-scale variation of electrical parameters when a power outage or other destabilizing event occurs. In the HOMER model, a variety of inputs are entered such as location coordinates, Generators, PV arrays, Wind Turbines, Batteries, Converters, Grid costs/usage, Solar resources, Wind resources, Temperatures, Fuels, and Electric Loads. HOMER's optimization and sensitivity analysis algorithms then evaluate the economic and technical feasibility of these technology options and account for variations in technology costs, electric load, and energy resource availability. The Navy can then use HOMER’s optimization and sensitivity results to compare to those of the SIREN model. The U.S. Department of Energy (DOE) Idaho National Laboratory (INL) possesses unique expertise and experience in the software, hardware, and systems design for the integration of renewable energy into the electrical grid. NAVFAC EXWC will draw upon this expertise to complete mission requirements.« less

Fragaria: a genus with deep historical roots and ripe for evolutionary and ecological insights.

PubMed

Liston, Aaron; Cronn, Richard; Ashman, Tia-Lynn

2014-10-01

The cultivated strawberry, Fragaria ×ananassa, is one of the youngest domesticated plants. Its 18th century origin via hybridization in Europe between the North American F. virginiana and the South American F. chiloensis was documented by the botanist Antoine Nicolas Duchesne. His 1766 "Natural History of Strawberries" is an extraordinary work that integrates fundamental discoveries on the biology, ecology, and phylogeny of Fragaria with applied information on cultivation and ethnobotanical uses, serving as an inspiration for current research in the genus. Fragaria species exhibit the full range of sexual systems in the gynodioecy pathway from hermaphroditism to dioecy (and back again), as well as variation in self-compatibility, and evidence of sex chromosomes with female heterogamety. The genus is also characterized by interspecific hybridization and polyploidy, with a natural range of ploidy levels from diploids to decaploids. This biological diversity, combined with the availability of genomic resources and the ease of growing and experimenting with the plants, makes Fragaria a very attractive system for ecological and evolutionary genomics. The goal of this review is to introduce Fragaria as a model genus and to provide a roadmap for future integrative research. These research directions will deepen our understanding of the ecological and evolutionary context that shaped the ancestors of the cultivated strawberry, not only providing information that can be applied to efforts to shape the future of this important fruit crop but also our understanding of key transitions in plant evolution. © 2014 Botanical Society of America, Inc.

Technical improvements in 19th century Belgian window glass production

NASA Astrophysics Data System (ADS)

Lauriks, Leen; Collette, Quentin; Wouters, Ine; Belis, Jan

Glass was used since the Roman age in the building envelope, but it became widely applied together with iron since the 19th century. Belgium was a major producer of window glass during the nineteenth century and the majority of the produced window glass was exported all over the world. Investigating the literature on the development of 19th century Belgian window glass production is therefore internationally relevant. In the 17th century, wood was replaced as a fuel by coal. In the 19th century, the regenerative tank furnace applied gas as a fuel in a continuous glass production process. The advantages were a clean production, a more constant and higher temperature in the furnace and a fuel saving. The French chemist Nicolas Leblanc (1787-1793) and later the Belgian chemist Ernest Solvay (1863) invented processes to produce alkali out of common salt. The artificial soda ash improved the quality and aesthetics of the glass plates. During the 19th century, the glass production was industrialized, influencing the operation of furnaces, the improvement of raw materials as well as the applied energy sources. Although the production process was industrialized, glassblowing was still the work of an individual. By improving his work tools, he was able to create larger glass plates. The developments in the annealing process followed this evolution. The industry had to wait until the invention of the drawn glass in the beginning of the 20th century to fully industrialise the window glass manufacture process.

Using species-specific paleotemperature equations with foraminifera: A case study in the Southern California Bight

Bemis, B.E.; Spero, H.J.; Thunell, R.C.

2002-01-01

Species-specific paleotemperature equations were used to reconstruct a record of temperature from foraminiferal ??18O values over the last 25 kyr in the Southern California Bight. The equations yield similar temperatures for the ??18O values of Globigerina bulloides and Neogloboquadrina pachyderma. In contrast, applying a single paleotemperature equation to G. bulloides and N. pachyderma ??18O yields different temperatures, which has been used to suggest that these species record the surface-to-thermocline temperature gradient. In Santa Barbara Basin, an isotopically distinct morphotype of G. bulloides dominates during glacial intervals and yields temperatures that appear too cold when using a paleotemperature equation calibrated for the morphotype common today. When a more appropriate paleotemperature equation is used for glacial G. bulloides, we obtain more realistic glacial temperatures. Glacial-interglacial temperature differences (G-I ??T) calculated in the present study indicate significant cooling (??? 8-10??C) throughout the Southern California Bight during the last glacial maximum (LGM). The magnitude of glacial cooling varies from ???8??C near the middle of the Southern California Bight (Tanner Basin and San Nicolas Basin) to ???9??C in the north (Santa Barbara Basin) and ???9.5-10??C in the south (Velero Basin and No Name Basin). Our temperature calculations agree well with previous estimates based on the modern analog technique. In contrast, studies using N. pachyderma coiling ratios, U37k??? indices, and transfer functions esfimate considerably warmer LGM temperatures and smaller G-I ??T. ?? 2002 Elsevier Science B.V.

Heating, weakening and shear localization in earthquake rupture

NASA Astrophysics Data System (ADS)

Rice, James R.

2017-08-01

Field and borehole observations of active earthquake fault zones show that shear is often localized to principal deforming zones of order 0.1-10 mm width. This paper addresses how frictional heating in rapid slip weakens faults dramatically, relative to their static frictional strength, and promotes such intense localization. Pronounced weakening occurs even on dry rock-on-rock surfaces, due to flash heating effects, at slip rates above approximately 0.1 m s-1 (earthquake slip rates are typically of the order of 1 m s-1). But weakening in rapid shear is also predicted theoretically in thick fault gouge in the presence of fluids (whether native ground fluids or volatiles such as H2O or CO2 released by thermal decomposition reactions), and the predicted localizations are compatible with such narrow shear zones as have been observed. The underlying concepts show how fault zone materials with high static friction coefficients, approximately 0.6-0.8, can undergo strongly localized shear at effective dynamic friction coefficients of the order of 0.1, thus fitting observational constraints, e.g. of earthquakes producing negligible surface heat outflow and, for shallow events, only rarely creating extensive melt. The results to be summarized include those of collaborative research published with Nicolas Brantut (University College London), Eric Dunham (Stanford University), Nadia Lapusta (Caltech), Hiroyuki Noda (JAMSTEC, Japan), John D. Platt (Carnegie Institution for Science, now at *gramLabs), Alan Rempel (Oregon State University) and John W. Rudnicki (Northwestern University).

The evolutionary mechanisms generating the tremendous biodiversity of islands have long fascinated evolutionary biologists. Genetic drift and divergent selection are predicted to be strong on islands and both could drive population divergence and speciation. Alternatively, strong genetic drift may preclude adaptation. We conducted a genomic analysis to test the roles of genetic drift and divergent selection in causing genetic differentiation among populations of the island fox (Urocyon littoralis). This species consists of six subspecies, each of which occupies a different California Channel Island. Analysis of 5293 SNP loci generated using Restriction-site Associated DNA (RAD) sequencing found support for genetic drift as the dominant evolutionary mechanism driving population divergence among island fox populations. In particular, populations had exceptionally low genetic variation, small Ne (range = 2.1-89.7; median = 19.4), and significant genetic signatures of bottlenecks. Moreover, islands with the lowest genetic variation (and, by inference, the strongest historical genetic drift) were most genetically differentiated from mainland grey foxes, and vice versa, indicating genetic drift drives genome-wide divergence. Nonetheless, outlier tests identified 3.6-6.6% of loci as high FST outliers, suggesting that despite strong genetic drift, divergent selection contributes to population divergence. Patterns of similarity among populations based on high FST outliers mirrored patterns based on morphology, providing additional evidence that outliers reflect adaptive divergence. Extremely low genetic variation and small Ne in some island fox populations, particularly on San Nicolas Island, suggest that they may be vulnerable to fixation of deleterious alleles, decreased fitness and reduced adaptive potential. © 2016 John Wiley & Sons Ltd.

Treatment of industrial exhaust gases by a dielectric barrier discharge

Volatile organic compounds (VOCs) in industrial exhaust gases were treated by a dielectric barrier discharge (DBD) operated with two different mobile power supplies. Together with the plasma source various gas diagnostics were used, namely fourier transform infrared (FTIR) spectroscopy, flame ionization detector (FID) and GC-MS. The analysis revealed that some exhaust gases consist of a rather complex mixture of hydrocarbons and inorganic compounds and also vary in pollutants concentration and flow rate. Thus, analysis of removal efficiencies and byproduct concentrations is more demanding than under laboratory conditions. This contribution presents the experimental apparatus used under the harsh conditions of industrial exhaust systems as well as the mobile power source used. Selected results obtained in a shale oil processing plant, a polymer concrete production facility and a yacht hull factory are discussed. In the case of total volatile organic compounds in oil processing units, up to 60% were removed at input energy of 21-37 J/L when the concentrations were below 500 mg/m3. In the yacht hull factory up to 74% of styrene and methanol were removed at specific input energies around 300 J/L. In the polymer concrete production site 195 ppm of styrene were decomposed with the consumption of 1.8 kJ/L. These results demonstrate the feasibility of plasma assisted methods for treatment of VOCs in the investigated production processes but additional analysis is needed to improve the energy efficiency.

As part of the FIRE/Extended Time Observations (ETO) program, extended time observations were made at San Nicolas Island (SNI) from March to October, 1987. Hourly averages of air temperature, relative humidity, wind speed and direction, solar irradiance, and downward longwave irradiance were recorded. The radiation sensors were standard Eppley pyranometers (shortwave) and pyrgeometers (longwave). The SNI data were processed in several ways to deduce properties of the stratocumulus covered marine boundary layer (MBL). For example, from the temperature and humidity the lifting condensation level, which is an estimate of the height of the cloud bottom, can be computed. A combination of longwave irradiance statistics can be used to estimate fractional cloud cover. An analysis technique used to estimate the integrated cloud liquid water content (W) and the cloud albedo from the measured solar irradiance is also described. In this approach, the cloud transmittance is computed by dividing the irradiance measured at some time by a clear sky value obtained at the same hour on a cloudless day. From the transmittance and the zenith angle, values of cloud albedo and W are computed using the radiative transfer parameterizations of Stephens (1978). These analysis algorithms were evaluated with 17 days of simultaneous and colocated mm-wave (20.6 and 31.65 GHz) radiometer measurements of W and lidar ceilometer measurements of cloud fraction and cloudbase height made during the FIRE IFO. The algorithms are then applied to the entire data set to produce a climatology of these cloud properties for the eight month period.

Does the history of food energy units suggest a solution to "Calorie confusion"?

PubMed

Hargrove, James L

2007-12-17

The Calorie (kcal) of present U.S. food labels is similar to the original French definition of 1825. The original published source (now available on the internet) defined the Calorie as the quantity of heat needed to raise the temperature of 1 kg of water from 0 to 1 degrees C. The Calorie originated in studies concerning fuel efficiency for the steam engine and had entered dictionaries by 1840. It was the only energy unit in English dictionaries available to W.O. Atwater in 1887 for his popular articles on food and tables of food composition. Therefore, the Calorie became the preferred unit of potential energy in nutrition science and dietetics, but was displaced when the joule, g-calorie and kcal were introduced. This article will explain the context in which Nicolas Clément-Desormes defined the original Calorie and the depth of his collaboration with Sadi Carnot. It will review the history of other energy units and show how the original Calorie was usurped during the period of international standardization. As a result, no form of the Calorie is recognized as an SI unit. It is untenable to continue to use the same word for different thermal units (g-calorie and kg-calorie) and to use different words for the same unit (Calorie and kcal). The only valid use of the Calorie is in common speech and public nutrition education. To avoid ongoing confusion, scientists should complete the transition to the joule and cease using kcal in any context.

Turbulence measurements using tethered balloon instrumentation during FIRE 1987

1990-01-01

As part of the surface-based observations conducted on San Nicolas Island, the U.K. Meteorological Office operated a set of turbulence probes attached to a balloon tether cable. Typically six probes were used, each capable of measuring momentum, heat, and humidity fluxes. Two probes were fitted with net radiometers, one positioned above cloud and the other below; a third probe carried a Lyman-alpha hygrometer fitted with a pre-heater for the measurement of total water content. Some preliminary results are presented from the 14th July describing the variation in structure of the cloudy boundary layer during the daytime. This day was characterized by a complete cloud cover, an inversion height of approximately 600 m. and north-westerly winds of approximately 6 m.s(-1). As an illustration the equivalent potential temperature derived from a profile ascent made between approximately 0830 and 0930 (PDT) is shown. The data has been smoothed to a height resolution of about 4 metres. At this time the cloud base was approximately 200 m. and very light drizzle was reaching the surface. The vertical velocity variance and potential temperature flux for two periods are shown; the first (shown by full lines) immediately follows the profile and the second (shown by dashed lines) is central around 1400 (PDT). The data have been normalized by their maximum values in the first period. Cloud base has now risen to approximately 300 m. There is a marked variation during the morning, particularly in sigma w. The net radiative flux above cloud top has by now reached its maximum value.

Dissociation against oxidation kinetics for the conversion of VOCs in non-thermal plasmas of atmospheric gases

Pasquiers, Stéphane; Blin-Simiand, Nicole; Magne, Lionel

2016-08-01

The kinetics of four volatile organic compounds (VOCs) (propene, propane, acetaldehyde, acetone) were studied in plasmas of atmospheric gases using a photo-triggered discharge (homogeneous plasma) or a dielectric barrier discharge (filamentary plasma). It was shown for the homogeneous plasma that quenchings of nitrogen metastable states, A3Ʃ+u and the group of singlets a' 1Ʃ-u, a 1Πg and w 1∆u, are important processes for the decomposition of such molecules. Recent measurements of the H2 concentration produced in the N2/C3H6 mixture emphasize that the hydrogen molecule can be an exit route for propene dissociation. It is also found that H2 and CO molecules are efficiently produced following the dissociation of CH3COCH3 and the subsequent chemical reactivity induced by radicals coming from acetone. Addition of oxygen to a N2/VOC mixture can change drastically the kinetics. However, the quenching processes of N2 metastables by the VOC are always present and compete with oxidation reactions for the conversion of the pollutant. At low temperature, oxidations by O or by OH are not always sufficiently effective to induce an increase of the molecule decomposition when oxygen is added to the mixture. In particular, the presence of O2 has a detrimental effect on the acetone removal. Also, as evidenced for acetaldehyde and propane, some kinetic analogies appear between filamentary and homogeneous plasmas.

Théodore Vetter (Strasbourg, 1916, June 19th - 2004, July 8th) was qualified as a medical doctor in medicine in 1948 in Strasbourg, and then followed complementary courses in medical biology in Paris. He realized most of his career as an adviser for medical research in pharmaceutical industry. He presented an early talent for drawing and graphic arts, encouraged by Georges Ritleng (1875-1972), headmaster of the School of decorative arts in Strasbourg. One expression of the artistic gift of Th. Vetter consisted in design and making of ex-libris, field in which he acquired an international reputation. In total, he realized about two hundred ex-libris, mostly for physicians. Also attracted by the history of medicine, he became a member of the Société Française d'Histoire de la Médecine; he was general secretary from 1965 to 1970, then he became vice-president and president from 1976 to 1978. He was the author of about a hundred works concerning the history of medicine; all were characterized by a great rigour and by the direct use of original sources. Among his main works, his studies on the oculist Jacques Daviel (1693-1762), popularizer of the surgery of cataract, on the surgeon Claude Nicolas Le Cat (1700-1768), on the birth of pathology, a commented edition of the complete works of Hippocrates, translated by M.P.E.

A control theoretical approach to crowd management. Comment on "Human behaviours in evacuation crowd dynamics: From modelling to "big data" toward crisis management" by Nicola Bellomo et al.

The formulation of mathematical models for crowd dynamics is one current challenge in many fields of applied sciences. It involves the modelization of the complex behavior of a large number of individuals. In particular, the difficulty lays in describing emerging collective behaviors by means of a relatively small number of local interaction rules between individuals in a crowd. Clearly, the individual's free will involved in decision making processes and in the management of the social interactions cannot be described by a finite number of deterministic rules. On the other hand, in large crowds, this individual indeterminacy can be considered as a local fluctuation averaged to zero by the size of the crowd. While at the microscopic scale, using a system of coupled ODEs, the free will should be included in the mathematical description (e.g. with a stochastic term), the mesoscopic and macroscopic scales, modeled by PDEs, represent a powerful modelling tool that allows to neglect this feature and provide a reliable description. In this sense, the work by Bellomo, Clarke, Gibelli, Townsend, and Vreugdenhil [2] represents a mathematical-epistemological contribution towards the design of a reliable model of human behavior.

I have read with great interest the paper [5] where the authors present an overview and critical analysis of the literature on the modeling of the crowd dynamics with special attention to evacuation dynamics. The approach developed is based on suitable development of methods of the kinetic theory. Interactions, which lead to the decision choice, are modeled by theoretical tools of stochastic evolutionary game theory [11,12]. However, the paper [5] provides not only a survey focused on topics of great interest for our society, but also it looks ahead to a variety of interesting and challenging mathematical problems. Specifically, I am interested in the derivation of macroscopic (hydrodynamic) models from the underlying description given from the kinetic theory approach, more specifically by the kinetic theory for active particles [8]. A general reference on crowd modeling is the recently published book [10].

A precession coordinate system (eccentricity -100Ka, obliquity -40Ka and precession -25Ka) developed by Milankovicht was the precession of the equinoxes, where the vernal point retrograde 1° every 72 years approximately and enter (0°) into the Aquarius constellation on March 20, 1940. On earth this entry was verify through: a) stability of the magnetic equator in the south central zone of Peru and in the north zone of Bolivia, b) the greater intensity of equatorial electrojet (EEJ) in Peru and Bolivia since 1940. The vernal point is a maximum conductivity sensitive axis in the EEJ given at the equinoxes. There was a relationship between the equatorial electrojet - magnetic equator - crust, and besides there was a long history of studies of coupling between earthquake-ionosphere that can be founded in the following revisions: Liperovsky et al. (1990); Gaivoronskaya (1991); Liperovsky et al. (1992); Parrot et al. (1993); Pulinets et al. (1994) and Gokhberg et al. (1995). In IUGG (2007), Cusco was propose as a prime meridian (72° W == 0°) that was parallel to the Andes; the objective was to synchronize the earth sciences phenomena (e.g. geology, geophysics, etc.). The coordinate system had the vernal point from meridian (72° W == 0°) and March 20, 1940. The retrograde movement of the vernal point was the first precessional degree (2012 = 1940 + 72); from the new prime meridian (72° W == 0°) it has obtained the opposite meridian (72° E == 180°). The first precessional degree (2012) near the meridian (72 ° E) was related to the date of April 11, 2012 where a massive earthquake of 8.6 on the Richter scale, followed by several aftershocks, one of 8.2 degrees struck Indonesia with epicenter near Banda Aceh. Five months after that date, Matthias Delescluse et.al (2012), Han Yue et.al (2012), and Fred F.

Detrital zircon provenance evidence for large-scale extrusion along the Altyn Tagh fault

The question of whether or not the Altyn Tagh fault is a large-scale extrusion boundary is critical for understanding the role of lateral extrusion in accommodating the Indo-Asian convergence and in building the Tibetan Plateau. Oligocene conglomerate clasts in the eastern Xorkol basin are low-grade slate, phyllite, sandstone, dacite and carbonate, and associated paleocurrent indicators evince sediment derivation from the opposing side of the Altyn Tagh fault. Matching these clasts with similar basement rocks in the North Qilian and Tuolainanshan terranes requires post-Oligocene left-lateral offset of 380 ?? 60 km on the eastern segment of the Altyn Tagh fault, suggesting large-scale extrusion along the fault in the Cenozoic (Yue, Y.J., Ritts, B.D., Graham, S.A., 2001b. Initiation and long-term slip history of the Altyn Tagh fault. International Geological Review 43, 1087-1094.). In order to further define this piercing point, the detrital zircon pattern of Oligocene sandstone from the Xorkol basin and the zircon ages of basement on the southern side of the fault were established by ion microprobe dating. Characterized by strong peaks between 850 and 950 Ma and the absence of Paleozoic and Mesozoic ages, the detrital zircon age pattern of the Oligocene sandstone matches the age distribution of zircon-bearing rocks of the Tuolainanshan terrane. This match requires 360 ?? 40 km of post-Oligocene left-lateral displacement on the eastern segment of the Altyn Tagh fault, supporting as well as refining the previously reported lithology-based cross-fault match. At least one of the following three extrusion scenarios must have existed to accommodate this large offset: (1) northeastward extrusion along the Altyn Tagh-Alxa-East Mongolia fault, (2) eastward extrusion along the Altyn Tagh-North Qilian-Haiyuan fault, and (3) northeastward extrusion of northern Tibet as a Himalaya-scale thrust sheet along the North Qilian-Haiyuan fault. We prefer the first scenario inasmuch as

Background: Exposure to disinfection by-products (DBPs) has been demonstrated to impair male reproductive health in animals, but human evidence is limited and inconsistent. Objective: We examined the association between exposure to drinking-water DBPs and semen quality in a Chinese population. Methods: We recruited 2,009 men seeking semen analysis from the Reproductive Center of Tongji Hospital in Wuhan, China, between April 2011 and May 2012. Each man provided a semen sample and a urine sample. Semen samples were analyzed for sperm concentration, sperm motility, and sperm count. As a biomarker of exposure to drinking-water DBPs, trichloroacetic acid (TCAA) was measured in the urine samples. Results: The mean (median) urinary TCAA concentration was 9.58 (7.97) μg/L (interquartile range, 6.01–10.96 μg/L). Compared with men with urine TCAA in the lowest quartile, increased adjusted odds ratios (ORs) were estimated for below-reference sperm concentration in men with TCAA in the second and fourth quartiles (OR = 1.79; 95% CI: 1.19, 2.69 and OR = 1.51; 95% CI: 0.98, 2.31, respectively), for below-reference sperm motility in men with TCAA in the second and third quartiles (OR = 1.46; 95% CI: 1.12, 1.90 and OR = 1.30; 95% CI: 1.00, 1.70, respectively), and for below-reference sperm count in men with TCAA in the second quartile (OR 1.62; 95% CI: 1.04, 2.55). Nonmonotonic associations with TCAA quartiles were also estimated for semen parameters modeled as continuous outcomes, although significant negative associations were estimated for all quartiles above the reference level for sperm motility. Conclusion: Our findings suggest that exposure to drinking-water DBPs may contribute to decreased semen quality in humans.

Ethnicity and infant mortality in Malaysia.

Dixon, G

1993-06-01

Malaysian infant mortality differentials are a worthwhile subject for study, because socioeconomic development has very clearly had a differential impact by ethnic group. The Chinese rates of infant mortality are significantly lower than the Malay or Indian rates. Instead of examining the obvious access to care issues, this study considered factors related to the culture of infant care. Practices include the Chinese confinement of the mother in the first month after childbirth ("pe'i yue") and Pillsbury's 12 normative rules for Malaysian Chinese care. Malay practices vary widely by region and history. Indian mothers are restricted by diet. Data-recording flaws do not permit analysis of Sarawak or Sabah. The general assumption that Western medicine favors better health for mothers and infants is substantiated among peninsular communities, however, there are also negative impacts which affect infant mortality. The complex interaction of factors impacting on infant mortality reported in seven previous studies is discussed. A review of these studies reveals that immediate causes are infections, injuries, and dehydration. Indirect causes are birth weight or social and behavioral factors such as household income or maternal education. Indirect factors, which are amenable to planned change and influence the biological proximate determinants of infant mortality, are identified as birth weight, maternal age at birth, short pregnancy intervals or prior reproductive loss, sex of the child, birth order, duration of breast feeding and conditions of supplementation, types of household water and sanitation, year of child's birth, maternal education, household income and composition, institution of birth, ethnicity, and rural residence. Nine factors are identified empirically as not significant: maternal hours of work in the child's first year, maternal occupation, distance from home to workplace, presence of other children or servants, incidence of epidemics in the child's first
