  5. MARIANE: MApReduce Implementation Adapted for HPC Environments

    SciTech Connect

    Fadika, Zacharia; Dede, Elif; Govindaraju, Madhusudhan; Ramakrishnan, Lavanya

    2011-07-06

    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 not 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).

  10. Nicolas and Eel submarine fans, California continental borderland

    Reynolds, S.; Gorsline, D.S.

    1987-04-01

    Nicolas and Eel Submarine Fans occur in the San Nicolas basin - an outer basin of the California continental borderland that has a low sedimentation rate. Nicolas Fan lies southeast of San Nicolas Island and the broad San Nicolas Bank. The upper fan is characterized by numerous channels. The midfan region may be divided into three distinct areas: a central midfan and two subfans. The central midfan deposition system is typical of Normark's suprafan. The subfans are essentially flat, sandy lobes. Eel Fan lies west of San Clemente Island and is fed by an erosional valley. Its midfan region may also be characterized as a flat, sandy lobe. Box-core data show that holocene turbidity currents have occurred on the central Nicolas Fan, whereas the subfans and Eel Fan are nearly inactive. The local tectonic regime influences these fans by determining slope trends, creating bathymetric obstacles, controlling canyon location, and triggering mass movements. Sea level changes affect sedimentation patterns of the fans by increasing the mean grain size and the amount of sediment delivered to the fan during lowstands. These changes may, in turn, affect the morphology of the fan. The characteristics of these fans represent variations of the generalized fan models described in the literature. 12 figures, 1 table.

    2007-07-01

    Under the influence of Supreme Ultimate of Neo-Confucianism, Zhang Jing-yue put forward the three theories of the Supreme Ultimate, viz., Supreme Ultimate of the Primordial Qi, Supreme Ultimate of the Heart, and Supreme Ultimate of the Vital Gate. These three theories were of trinity relationship, forming the basic frame of Jingyue's system of medical theories. Among them, the theory of Supreme Ultimate of the Primordial Qi was the foundation of natural concept in his medical theories, the theory of Supreme Ultimate of the Vital Gate was the teleology of his medical theories, and the theory of Supreme Ultimate of the Heart, as a cognitive method, was the methodology of his medical theories. Jing-yue' s medical theories were constructed on these three corner-stays, which was a tremendous leap forward in the development of traditional Chinese medicine and Neo-Confucianism.

    2013-01-01

    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 ).

    Guancha tetela was originally described as a species having a peduncle and a skeleton exclusively composed of sagittal triactines. Therefore, according to the most recent phylogeny of Clathrinida, it should be placed in the genus Clathrina. This species was collected on the Northeastern Brazilian coast in 1968 and it was not collected again until 2011 in Curaçao. In this study, we reanalyzed the type material and the new specimens from Curaçao under a morphological-molecular approach. Morphological analysis revealed the presence of tetractines in the skeleton of all the studied specimens, including a slide of the holotype. In the molecular phylogeny G. tetela grouped with genera containing tetractines, but as an independent new lineage, different from all the other genera of Clathrinida. Based on these results, we propose the erection of a new genus, Nicola gen. nov., to include species whose body is composed of tubes without anastomosis nor branches but that run in parallel and coalesce at the apical and basal regions. Moreover, the skeleton is exclusively composed of sagittal triactines and tetractines.

  7. 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.

    In 1951, The Interim Regulations on Practitioners of Traditional Chinese Medicine was issued by the Ministry of Health to restrict the practitioners' practice of traditional Chinese medicine (TCM) and to transform TCM, resulting in TCM facing the risk of interrupting its inheritance and development. In 1953, Yue Meizhong, a famous TCM physician, drafted a proposal about TCM development. After discussing and revising with Li Zhensan, the Director of North China Institute of TCM Experiment, the proposal was submitted to the Central Committee of Chinese Communist Party and Government Administration Council as a reference. The proposal made a retrospect of the long history of TCM development, elaborated the characteristic and significance of TCM, proposed the detailed suggestions about the establishment of TCM administration institutions at various levels, set up of TCM Academy and Colleges etc., which represented the voice of TCM professionals, and reflected the objective principle of TCM development.

    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.

    Winds and turbulence above San Nicolas Island (SNI) were continuously monitored during the First ISCCP Regional Experiment (FIRE) with a Doppler sodar (1600 Hz) and an ultrahigh frequencies (UHF) (400 MHz) wind profiler. Individual profiles were logged from 1 through 19 July 1987 at 30 sec to 2 min intervals; preliminary processing of hourly averaged winds from 100 to 2300 m is complete. These wind profiles have been combined with intermittent radiosonde profiles to construct time-height sections of parameters such as the Richardson Number. Analysis now in progress includes interpretation of the sodar (C 2/T) and profiler (C 2/N, C 2/q) reflectivity profiles. These profiles are being combined with radiometric and ceilometer data for investigations of vertical transport and cloud base/top entrainment processes. Finally, by using the SNI data in conjunction with soundings made from the research vessel Pt. Sur, the relationship between changes in the SNI winds and mesoscale and synoptic-scale weather features is being investigated.

    Vandals and other missiles are launched occasionally from San Nicolas Island, CA, during Naval exercises and tests. Pinnipeds on the island beaches are exposed to the flight sounds, some of which are sonic booms from directly overhead. Environmental concerns led the Navy to support acoustic studies of the missile sounds at the beaches. The results show flat-weighted sound pressures from Vandals as high as 150 dB re: 20 μPa(peak) [140 dB re: 20 μPa(rms)] at a near-vertical distance of 400 m. Other flat-weighted pressures from Vandals were as low as 107 dB re: 20 μPa(peak) [95 dB re: 20 μPa(rms)] at a beach 3.9 km horizontally behind the launcher. Pulse durations and sound exposure levels were also measured. One-third octave band sound exposure levels were measured. All parameters (except one-third octave band levels) were also measured with A weighting. Other missiles measured include Tomahawk cruise missiles, Rolling Airframe Missile, Advanced Gun System, Terrier, and the Supersonic Sea-Skimming Target. [Work supported by U.S. Navy.

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.

    The Anatomy Lesson of Dr. Nicolaes Tulp was painted by Rembrandt Harmen-szoon van Rijn at the early age of 26 years. In the XVII century these paintings were very popular in the Netherlands, and in this country the cities flourished as cultural centers searching the anatomy knowledge. Nicolaes Tulp was one of the persons in the center of Amsterdam's scene during XVII century. In 1632 Tulp was 39 years old, and he was an anatomist and a surgeon. Rembrandt masterly shows an autopsy performed by Dr. Tulp. This picture is the description of the beginning of a medical intellectual utopia: the absolute visibility of the disease. Unfortunately this utopia is blind to the complete visibility of the psycho-socio-cultural dimensions of the ill.

    1985-01-01

    During the Neogene, the Mediterranean was a rather unique biogeographic province. For this reason, first and last occurrences of Neogene species recorded in the Mediterranean region may not be synchronous with those recorded in the open oceans. This has important implications as most of the Neogene stage boundaries are defined on the basis of Mediterranean type sections. The most direct way to determine the relative timing of Mediterranean and open ocean datums is through correlation with the polarity time scale. Such correlations are not available for the Mediterranean Pliocene. The Trubi pelagic limestones and Monte narbone marls which characterize the SicilianPliocene are not ideal for magnetic stratigraphy due to weak remnant intensities and an ubiquitous normal polarity overprint. However, at Monte San Nicola, a magnetic stratigraphy has been resolved by stepwise demagnetization in small temperature increments. The upper and lower bounds of the Gauss Epoch, and the Mammoth and Kaena polarity events can be correlated to well defined planktonic foraminiferal and calcareous nannofossil datums. Hence the synchronism of these datums between the Mediterranean and the open ocean can be tested. The most notable discrepancy is in the last occurrence of G. margaritae which occurs at the base of the Gauss in most open marine sections, but is found at the top of the Gilbert at Monte San Nicola.

    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.

    A study is presented of surface measurements made at San Nicolas Island during the intensive field observation marine stratocumulus phase of the First International Satellite Cloud Climatology Program Regional Experiment, July 1987, to retrieve the average diurnal variation of marine stratocumulus and associated surface variables. The diurnal behavior of the cloud base appears to be consistent with model-predicted uncoupling of the cloud layer and the subcloud layer as the turbulent flux of moisture is limited by solar heating close to the cloud base. Also, variation in surface air temperature is consistent with the limitation of the turbulent flux of heat between the two layers, screening the surface from the effect of longwave cooling from the cloud top.

    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.

    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.

  1. Status of the Island Night Lizard and Two Non-Native Lizards on Outlying Landing Field San Nicolas Island, California

    More than 900 individually marked island night lizards (Xantusia riversiana) were captured on San Nicolas Island, California, between 1984 and 2007 as part of an ongoing study to monitor the status of this threatened species. Our data suggest that at least a few lizards are probably more than 20 years old, and one lizard would be 31.5 years old if it grew at an average rate for the population. Ages of 20 and 30 years seem reasonable given the remarkably slow growth during capture intervals of more than a decade for five of the lizards which we estimated to be 20 or more years old. Like other lizards, island night lizard growth rates vary by size, with larger lizards growing more slowly. In general, growth rates were somewhat greater on San Nicolas Island (compared with Santa Barbara Island), and this increase was sustained through all of the intermediate size classes. The higher growth rate may account for the somewhat larger lizards present on San Nicolas Island, although we cannot discount the possibility that night lizards on San Nicolas are merely living longer. The high percentage of small lizards in the Eucalyptus habitat might seem to reflect a healthy population in that habitat, but the high proportion of small lizards appears to be caused by good reproduction in the 1900s and substantially poorer reproduction in subsequent years. The Eucalyptus habitat has dried quite a bit in recent years. Night lizards in the Haplopappus/Grassland habitat have shown an increase in the proportion of larger lizards since 2000. There has also been an increase in the proportion of large lizards in the Rock Cobble habitat at Redeye Beach. However, there are has been some change in habitat with more elephant seals occupying the same area just above the high tide as do the night lizards. Southern alligator lizards and side-blotched lizards are both non-native on San Nicolas Island. Neither lizard causes obvious harm to island night lizards, and management time and effort should

    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.

    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.

    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.

    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.

    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.

    2016-01-01

    The earliest mammaliaforms are difficult to assess because the fossil record is poor and because their distinctive morphologies cannot be directly compared with more recent mammaliaforms. This is especially true for the haramiyid genus Theroteinus, only known in the Saint-Nicolas-de-Port locality (Rhaetian, France). This study presents a new definition of the type-species Theroteinus nikolai. A new species Theroteinus rosieriensis, sp. nov., is named and distinguished by the lingual shift of distal cusps, a larger size, and a stockier occlusal outline. Comparisons with Eleutherodon, Megaconus and Millsodon suggest that Theroteinus has potential close relatives among the Jurassic haramiyids. PMID:27781174

    The detection of subsurface cavities, such as crypts, cellars and tunnels, in churches and castles belongs to successful applications of the employment of surface gravity measurement techniques in archaeo-prospecting. The old historic building exploration requires using of non-invasive methods, and hence the microgravity technique is a proper candidate for this task. On a case study from the Roman-Catholic Church of St. Nicolas in the town Pukanec the results of using microgravity for detection and delineation of local density variations caused by a near-surface void are shown. The acquired negative anomaly in the residual Bouguer anomalies field suggested the presence of a possible void feature. Euler deconvolution and 3D modelling were used to estimate the depth and shape of the anomalous source. Additionally, measurements of the vertical gravity gradient on several stations were performed. We tested how the use of a downward continuation of gravity, utilizing the real vertical gravity gradient, influences the shape and amplitude of the final Bouguer anomaly map.

    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.

    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.

    The development of in situ, cheep, noninvasive, and fast strategies for soil monitoring is a crucial task for environmental research. In this paper, we present the results of three field surveys carried out in an industrial area of Southern Italy: S. Nicola di Melfi. The monitoring procedure is based on soil magnetic susceptibility measurements carried out by means of experimental protocols that our research group developed during the last years. This field surveys is supported by both geological characterization of the area and analytical determinations of metal concentrations in soils. Magnetic studies were carried out not only in situ but also in laboratory. Results show that, taking into account the influence due to the geomorphologic difference, soil magnetic susceptibility is an optimal indicator of the anthropogenic impact. So, our monitoring strategy discloses that the combined use of magnetic susceptibility measurements and soil geomorphology information may be used as a useful tool for the temporal monitoring of pollution evolution and for a fast screening of polluted zones.

    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.

    Five members of the Le Camus family of Paris were apothecary-grocers, a situation passed down from father to son from the end of the reign of Charles VII up to the reign of Louis XIV, in other words for nearly two centuries. Four of them were called Nicolas and the fifth Jehan. Nicolas I practised his trade in the Rue Saint-Antoine; Nicolas II and Jehan lived in the district of Les Halles, on the corner of the Rue Saint-Denis and the Rue de la Chanvrerie. Nicolas IV was a tenant in a house at the crossroads of the Rue Saint-Honoré and the Rue des Poulies, later absorbed by the opening of the Rue du Louvre. In 1638, Nicolas IV bought the house known as "Le Pavillon des Singes" on the corner of the Rue Saint-Honoré and the Rue des Vieilles Etuves (now the Rue Sauval), the home of the family of Jean Pocquelin, father of Jean-Baptiste, the future Molière. When Nicolas IV died, his goods were divided between his son François, lawyer in Parliament, and his daughter Anne who inherited the "Pavillon des Singes". In 1680, she sold it to an administrator of the Hôtel-Dieu. Nicolas IV Le Camus was the last Parisian apothecary of this dynasty and no other Le Camus practised pharmacy in Paris until the Royal Declaration of 25th April 1777 which created the College of Pharmacy and the Master of Pharmacy.

    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

During his voyage, he wanted to visit German colleagues and to have the opportunity to examine their instruments. His objective since several years was to collect original data of observations. When being in Nuremberg and Berlin, he made a search concerning the observations performed by Eimmart and G. Kirch, later in Danzig, he succeeded to buy Hevelius's manuscripts. After staying in Russia for 22 years, where he was the founder of the Petersburg Observatory, Delisle came back to France in the year 1747. During his return trip (two and a half months) he visited libraries in Prussia showing interest to their manuscripts and to some curiosities. Then in the surroundings of Wittenberg, he visited count von Löser's collection of instruments. In Berlin, he met the Feldmarschall von Schmettau and Grischow; but the previously seen colleagues were dead. During all these years, Delisle had enlarged the circle of his acquaintances, which has been very useful to launch the ``avertissements'' to recommend observations of some peculiar astronomical phenomena. The expeditions in 1761 for the transit of Venus owe a lot to him.

    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).

    Very few science books circulated amongst the European scientists, with so efficiency as Lemery's. His Course of Chemistry has been published 18 times in French and has been translated in Latin, English, German, Spanish, Italian and Deutch. His Treaty or Dictionnary of Drugs has been published 14 times in French and translated in foreign languages. His Universal Pharmacopeia has not been published less than 17 times in French and has also been translated in foreign languages. The longevity of these books was quite unusual, because, for exemple, his Dictionnary, first published in 1698, was published again in 1807!

    N. Rashevsky (1899-1972) was one of the pioneers in the application of mathematics to biology. With the slogan: mathematical biophysics : biology :: mathematical physics ; physics, he proposed the creation of a quantitative theoretical biology. Here, we will give a brief biography, and consider Rashevsky's contributions to mathematical biology including neural nets and relational biology. We conclude that Rashevsky was an important figure in the introduction of quantitative models and methods into biology.

    The treatises of Durand on architecture were studied in order to set them in a wider context. An attempt was made to demystify the negative image of Durand by presenting an honest judgement and a new interpretation. Many paradoxical statements were discovered, and discussed in the light of modern architecture. Seen from the topical architecture debate, a new image appeared, making Durand's theory transparent by the confrontation with those of some philosophers and architects today.

    In the 1970s about 1,650 southern sea otters (Enhydra lutris nereis) were restricted to the central California coast (Riedman and Estes, 1990), and a high volume of oil was being shipped through the region. Because of the vulnerability of sea otters to contamination from oil (Costa and Kooyman, 1982; Williams and Davis, 1995) that would likely spread wide- ly along the shore after a large spill (Van- Blaricom and Jameson, 1982), the subspecies was listed as threatened in 1977 under the United States Endangered Species Act.

    Glass, I. S.

    La Caille was one of the observational astronomers and geodesists who followed Newton in developing ideas about celestial mechanics and the shape of the earth. He provided data to the great 18th-century mathematicians involved in understanding the complex gravitational effects that the heavenly bodies have on one another. Observing from the Cape of Good Hope, he made the first ever telescopic sky survey and gave many of the southern constellations their present-day names. He measured the paths of the planets and determined their distances by trigonometry. In addition, he made a controversial measurement of the radius of the earth that seemed to prove it was pear-shaped. On a practical level, La Caille developed the method of `Lunars' for determining longitudes at sea. He mapped the Cape. As an influential teacher he propagated Newton's theory of universal gravitation at a time when it was only beginning to be accepted on the European continent. This book gives the most comprehensive overview so far available of La Caille's life and work, showing how he interacted with his often difficult colleagues. It places special emphasis on his life at, and his observations and comments on, the Cape of Good Hope, where he spent the years 1751-53.

  10. From Marianism to terrorism: the many faces of violence against women in Latin America.

    PubMed

    Rondon, M B

    2003-08-01

    Violence against women is widespread and highly tolerated in Latin America. In this paper, I will argue that this is because violence stems from deep cultural roots and because women are brought up in a patriarchal familial organization which promotes passivity and dependence. Traditional religious culture, which poses the Virgin Mary figure as role model, is ambivalent and distorted, repressing sex while overvaluing motherhood and self denial and demeaning women who do not conform to the established stereotypes. Patriarchal violence has serious emotional consequences for women. The stressful violent circumstances in women's lives lead to increased drug abuse that further exposes them to police and institutional violence. Political instability and civil wars in South America have caused many deaths, and have left many women with traumatic sequelae. Efforts at improving quality of life and diminishing violent conditions for women and girls in Latin America should include consideration of local cultural, political and economic peculiarities.

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

    NASA Astrophysics Data System (ADS)

    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.

    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.

    A sample of oil coming from the case containing the relics of St. Nicholas the Great, preserved in the church of "San Nicolò al Lido" (Venice, Italy), has been characterised by the determination of its chemical composition, its age (radiocarbon dating) and the presence of particles of biological origin. Experimental results show that the sample is a vegetal oil, with a fatty acids composition modified by natural oxidation processes, containing pollen grains of plants from Northern Italy, and dating around 1300 A.D. These results together with an historical and artistic evaluation of the ceramic jar containing the oil, allow us to hypothesise that the jar was introduced into the case after the arrival of the relics in Venice (1100 A.D.) during one of the official inquisitions prior to that documented in 1399 A.D.

    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].

    The study of human behavior is a complex task, but modeling some aspects of this behavior is an even more complicated and exciting idea. From crisis management to decision making in evacuation protocols, understanding the complexity of humans in stress situations is more and more demanded in our society by obvious reasons [5,6,8,12]. In this context, [4] deals with crowd dynamics with special attention to evacuation.

    Paper [3] presents a survey and a critical analysis on models of crowd dynamics derived to support crisis management related to safety problems. This is an important topic which can have an important impact on the wellbeing of our society. We are very interested in this topic as we operate in a country, Saudi Arabia, where huge crowds can be present and that stress conditions can be occasionally induced by non predictable events. In these situations the problem of crisis management is of fundamental importance.

    Total reconstruction of a historical object is a complicated process consisting of several partial steps. One of these steps is acquiring high-quality data for preparation of the project documentation. If these data are not available from the previous periods, it is necessary to proceed to a detailed measurement of the object and to create a required drawing documentation. New measurement of the object brings besides its costs also several advantages as complex content and form of drawings exactly according to the requirements together with their high accuracy. The paper describes measurement of the Baroque church by the laser scanning method extended by the terrestrial and air photogrammetry. It deals with processing the measured data and creating the final outputs, which is a 2D drawing documentation, orthophotos and a 3D model. Attention is focused on their problematic parts like interconnection of the measurement data acquired by various technologies, creation of orthophotos and creation of the detailed combined 3D model of the church exterior. Results of this work were used for preparation of the planned reconstruction of the object.

    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.

    In this comprehensive review concerning the modelling of human behaviours in crowd dynamics [3], the authors explore a wide range of mathematical approaches spanning over multiple scales that are suitable to describe emerging crowd behaviours in extreme situations. Focused on deciphering the key aspects leading to emerging crowd patterns evolutions in challenging times such as those requiring an evacuation on a complex venue, the authors address this complex dynamics at both microscale (individual level), mesoscale (probability distributions of interacting individuals), and macroscale (population level), ultimately aiming to gain valuable understanding and knowledge that would inform decision making in managing crisis situations.

    A personal comment on a scientific paper is unavoidably related to the personal education and bias. This statement allows me to apologize about the fact that my comment mainly focuses on a somewhat narrow field, namely to analytic topics related to modeling behavioral crowds. The remarks in the following aim also to induce further research suggestions from the authors of paper [3]. In more detail I bring to the attention of the authors of [3] and I look forward to their reply in view of future activity in this field: The micro-macro derivation of hydrodynamic type models should lead to hyperbolic type models, where the propagation speed of perturbation is finite, see [4]. However, it would be interesting understanding how far parabolic type models [6], and their possible modifications, can be accepted as an approximation of physical reality [8].

    The review presented by Bellomo et al. [1] addresses the modelling approaches employed to represent human behaviour in evacuation in a comprehensive manner. The authors discuss crowd evacuation modelling in light of crisis management, a relevant and current topic given the recent escalation of terrorist threats all over the world. The need for designing buildings for rapid evacuation using crowd evacuation models has been recently raised in important forums [2]. This research area is strictly linked to the field of Fire Safety Engineering.

    The management of human crowds in extreme situations is a complex subject which requires to take into account a variety of factors. To name a few, the understanding of human behaviour, the psychological and behavioural features of individuals, the quality of the venue and the stress level of the pedestrian need to be addressed in order to select the most appropriate action during an evacuation process on a complex venue. In this sense, the mathematical modeling of such complex phenomena can be regarded as a very useful tool to understand and predict these situations. As presented in [4], mathematical models can provide guidance to the personnel in charge of managing evacuation processes, by means of helping to design a set of protocols, among which the most appropriate during a given critical situation is then chosen.

    The recent review paper [4] constitutes a valuable contribution on the understanding, modeling and simulation of crowd dynamics in extreme situations. It provides a very comprehensive revision about the complexity features of the system under consideration, scaling and the consequent justification of the used methods. In particular, macro and microscopic models have so far been used to model crowd dynamics [9] and authors appropriately explain that working at the mesoscale is a good choice to deal with the heterogeneous behaviour of walkers as well as with the difficulty of their deterministic identification. In this way, methods based on the kinetic theory and statistical dynamics are employed, more precisely the so-called kinetic theory for active particles [7]. This approach has successfully been applied in the modeling of several complex dynamics, with recent applications to learning [2,8] that constitutes the key to understand communication and is of great importance in social dynamics and behavioral sciences.

    Escherichia coli (E. coli) is a commensal bacterium of the gastro-intestinal tract of human and vertebrate animals, even if the aquatic environment could be considered as a secondary habitat. During turbids events consecutive to the rainfall, E.coli are released from manure and feces in karstic hydrosystem with different settling velocities, related to their association to particles. In water, survival of E. coli, was dependant to the grazing by protozoans and their ability to overcome environmental stress. In these conditions, viable but non culturable (VNC) population of E. coli, could be observed. The aim of this study was to investigate, in a small well characterized rural karstic watershed (i) the structure of E. coli population based on the survival ability, the distribution in four main phylo-groups (A, B1, B2, D), and the phenotypic characteristics, (ii) the fate and the distribution of viable non culturable E. coli according their settling velocities, from surface water to groundwater. For this purpose we combined microbiology and hydrology approaches, and solid phase cytometry (ChemScan°RDI) methodology was performed to numbered VNC E. coli. The distribution in the four main E. coli phylo-groups (A, B1, B2, D) shown that the E. coli population structure was modified not only by the hydrological conditions but also the use of the watershed (presence of cattle). Survival abilities of E. coli strains based on microcosm experiments, vary from 2 days to at least 14 days. Characterization of E. coli was performed by studying specific traits present in host-associated strains (virulence factors, antibiotic resistance) and those that could be involved in water persistence (growth temperature substrate range, biofilm formation and grazing by protozoa). Three major clusters of strains were defined by using a correspondence factor analysis. In water characterized by high level of fecal contamination a first cluster of E. coli strains was related to A and B2 phylo-group, presented a multiple-antibiotic-resistance profile, and had low survival abilities in water. In slightly contaminated water, E. coli strains were persistent in water, sensitive to antibiotics, and able to develop at low temperature (from 7°C to 20°C) and to degrade macromolecules. In the same karstic hydrosystem, whatever the hydrological conditions, a population of E. coli in VNC state was observed, even in dry period where VNC E. coli raised to 96% of the total viable E. coli population. The distribution of the E. coli VNC population according to their settling velocity varies along the transfer between the swallow hole to the spring. Thus rapid flow inside karstic aquifer supports the culturability of E. coli. In contrast, in during low-flow period with slow transport of contaminant, E. coli lose their culturability but could maintained inside in VNC state in such hydrosystem.

    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

    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.''

    If you are a subscriber to Newsweek, you probably remember these stories from the past few months: “Vaccine Revolution,” “Aliens Invade America!,” “A Gymnast's Long Fall,” “Is AIDS Forever?,” and a cover story, “Science Finds God.” They all had something in common, aside from their science focus: at the end of each article was the credit line, “With Marian Westley.” In addition, a story titled “A Long, Wacky Summer,” on recent weather patterns, carried Marian Westley's byline. Who, you may have wondered, is this Marian Westley, who reports with equal aplomb on matters as diverse as epidemiology, meteorology, the predations of nonnative plant species, and the interface between scientists and theologians? Actually, Westley is a graduate student in biological oceanography at the University of Hawaii and a member of AGU. She spent the summer of 1998 as the AAAS/AGU Mass Media Fellow at Newsweek in New York.

The journal Science has called it a "Cantonese cancer". We propose that in fact NPC is a cancer that originated in the Bai Yue ("proto Tai Kadai" or "proto Austronesian" or "proto Zhuang") peoples and was transmitted to the Han Chinese in southern China through intermarriage. However, the work by John Ho raised the profile of NPC, and because of the high incidence of NPC in Hong Kong and Guangzhou, NPC became known as a Cantonese cancer. We searched historical articles, articles cited in PubMed, Google, monographs, books and Internet articles relating to genetics of the peoples with high populations of NPC. The migration history of these various peoples was extensively researched, and where possible, their genetic fingerprint identified to corroborate with historical accounts. Genetic and anthropological evidence suggest there are a lot of similarities between the Bai Yue and the aboriginal peoples of Borneo and Northeast India; between Inuit of Greenland, Austronesian Mayalo Polynesians of Southeast Asia and Polynesians of Oceania, suggesting some common ancestry. Genetic studies also suggest the present Cantonese, Minnans and Hakkas are probably an admixture of northern Han and southern Bai Yue. All these populations have a high incidence of NPC. Very early contact between southern Chinese and peoples of East Africa and Arabia can also account for the intermediate incidence of NPC in these regions.

  15. Probing calculated O2+ potential-energy curves with an XUV-IR pump-probe experiment

    We study dissociative photoionization of molecular oxygen in a kinematically complete XUV-IR pump-probe experiment. Detecting charged fragments and photoelectrons in coincidence using a reaction microscope, we observe a pump-probe delay-dependent yield of very low energetic O+ ions which oscillates with a period of 40 fs . This feature is caused by a time-dependent vibrational wave packet in the potential of the binding O2+(a Π4u) state, which is probed by resonant absorption of a single infrared photon to the weakly repulsive O2+(f Π4g) state. By quantitative comparison of the experimental kinetic-energy-release (KER) and quantum-beat (QB) spectra with the results of a coupled-channel simulation, we are able to discriminate between the calculated adiabatic O2+ potential-energy curves (PECs) of Marian et al. [Marian, Marian, Peyerimhoff, Hess, Buenker, and Seger, Mol. Phys. 46, 779 (1982), 10.1080/00268978200101591] and Magrakvelidze et al. [Magrakvelidze, Aikens, and Thumm, Phys. Rev. A 86, 023402 (2012), 10.1103/PhysRevA.86.023402]. In general, we find a good agreement between experimental and simulated KER and QB spectra. However, we could not reproduce all features of the experimental data with these PECs. In contrast, adjusting a Morse potential to the experimental data, most features of the experimental spectra are well reproduced by our simulation. By comparing this Morse potential to theoretically predicted PECs, we demonstrate the sensitivity of our experimental method to small changes in the shape of the binding potential.

    Why does Mary hold her prominent place in Catholic theology to the extent that five specific dogmas have developed around her? Psychoanalytic theory suggests dogma arises out of the psychic needs of people and psychic needs of people are expressed in dogma. The early views of Erich Fromm, a disciple of Freud, are presented to demonstrate that Marian dogma arose from the psychic needs of the people. The views of both Catholic and Protestant thinkers are presented, as well as theological and psychiatric views.

  3. Gender and the pre-1945 American Planetarium Community

    NASA Astrophysics Data System (ADS)

    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.

  4. 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.

    2000-01-01

    The primary objective of the STS-99 mission was to complete high resolution mapping of large sections of the Earth's surface using the Shuttle Radar Topography Mission (SRTM), a specially modified radar system. This radar system produced unrivaled 3-D images of the Earth's Surface. This videotape shows a science press briefing. The panel members are Michael Kobrick, the SRTM Project Scientist at JPL; Thomas Henning, SRTM Program Manager at the National Imagery and Mapping Agency; Diane Evans, the Director of the Earth Sciences Program at NASA; and Marian Werner, XSAR Project Manager for the DLR, Deutschen Zentrum fur Luft- und Raumfahrt, Germany's National Aerospace Research Center. Michael Kobrick explained the mechanics of interferometric measurements of the Earth. He explained and demonstrated with a scale model the deployable mast's use. He also explained the importance of the attitude and orbit determination avionics. A brief animated video showing how four beams would give a 225 km wide swath of the Earth topography was viewed. Thomas Henning discussed some of the usage of the digital terrain elevation data for flood relief planning, cell phone station placement, military planning for command and control centers, and flight simulation. He explained that public access to the most precise data would be limited. Diane Evans described data usage in flood prediction, earthquake fault identification and archeology. Marian Werner described the German and Italian input to the project. The questions from the press concerned the time to process this data, and the reasons for the limited access to the more precise data.

  7. Angiotensin II: a candidate for an aldosterone-independent mediator of potassium preservation during volume depletion.

    PubMed

    Hoover, Robert S

    2011-02-01

    Two different stimulators of aldosterone secretion, high-potassium diet and low-sodium diet, have disparate effects on potassium secretion in the distal nephron. The mechanism by which the kidney preserves potassium in the face of a high-aldosterone, volume-depleted state has engendered much thought. Yue et al. now propose that angiotensin II inhibits the renal outer medullary potassium channel (ROMK1) through stimulation of the protein tyrosine kinase c-Src, perhaps acting as a signal to differentiate volume depletion from a high-potassium diet.

    Thompson, Bruce E.

    1980-11-01

    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.

  13. 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.

  14. 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.

    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.

  12. 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

  13. Magnetism of quaternary sediments

    NASA Astrophysics Data System (ADS)

    Heller, Friedrich

    Magnetism of Quaternary sediments was the topic of a well-attended symposium held during the 13th INQUA (International Union of Quaternary Research) congress in Beijing, China, August 2-9. More than 40 papers were delivered by scientists from Belgium, England, France, Germany, Japan, New Zealand, Sweden, Switzerland, Taiwan, the United States, the Soviet Union, Yugoslavia, and other countries. The host country contributed to a productive session that was part of the first large scientific meeting to take place in Beijing after the June 4, 1989, upheaval.Nearly half of the studies focused on paleomagnetic and rock magnetic properties of loess in Alaska, Central Asia, China, and New Zealand. Magnetostratigraphic polarity dating was done at some sections in the western (Shaw et al.) and central Chinese loess plateau (Bai and Hus; Wang and Evans; Yue). The interpretation of the polarity pattern found in the western loess plateau still is not unambiguous. In the central part, certain polarity boundaries, such as the Brunhes/Matuyama (B/M) boundary, are found in slightly different stratigraphic positions (Hus et al.; Yue). In deep-sea sediments the lock-in depth of natural remanent magnetization (NRM) at the B/M boundary seems to be a linear function of sedimentation rate (de Menocal et al.). Although the magnetization process in the Chinese loess is not well understood, detailed records of polarity transitions have been reported for the B/M and the Jaramillo R→N transition (Ma et al.; Rolph).

    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.

    1994-07-01

    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.

    2016-03-01

    The accuracies of molten slag viscosity fitting and low-temperature extrapolation were compared between four two-variable models: Arrhenius, Weymann-Frenkel (WF), and Vogel-Fulcher-Tammann (VFT) and Mauro, Yue, Ellison, Gupta and Allan (MYEGA) models with constant pre-exponential parameter, based on a molten slag viscosity database consisting of over 800 compositions and 5,000 measurements. It is found that over wide ranges of pre-exponential parameter, the VFT and MYEGA models have lower viscosity fitting errors and much higher low-temperature viscosity extrapolation accuracies than Arrhenius and WF models. The pre-exponential parameter values of -2.8 for VFT and -2.3 for MYEGA are recommended.

    Large breeding populations of California sea lions (Zalophus californianus) are located on San Miguel and San Nicolas Islands in the Southern California Bight. In 2001, there was a substantial increase in pup mortality in late summer and fall. From June 2002 to January 2003, 208 freshly dead pups were examined on San Miguel Island, the most western of the Channel Islands off the coast of southern California. Tissues from 186 of these pups were examined histologically. The primary lesions in 133 (72%) of the pups were an enteritis associated with hookworms and infections in major organs. Emaciation/starvation in 43 pups (26%) was the second most important cause of death.

    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.

    Nicolas de la Caille, James Dunlop and John Herschel compiled the first three catalogues of southern star clusters and nebulae. Lacaille catalogued 42 objects from Cape Town, South Africa, in 1751 and 1752. Dunlop catalogued 629 objects from Parramatta, Australia, in 1826 and Herschel catalogued 1708 objects between 1834 and 1838 from Cape Town. Many of these objects had not been seen before; In this paper we discuss the new discoveries and the accuracy of the positions supplied by Lacaille, Dunlop and Herschel. Half of Dunlop's 629 objects turned out to be asterisms and faint double stars.

    Written on the seal of the University of Bologna - founded in 1088 and regarded as the oldest degree-granting university in the western world - are the words Alma mater studiorum. Translated into English, they mean, literally, "Nourishing mother of studies", which is apt given that the university's almuni include the astronomers Nicolas Copernicus and Giovanni Domenico Cassini - the first to observe Saturn's four moons. But Bologna has a much more recent claim to fame in the world of education: it was at the university that plans to create a common European higher-education system were set in motion exactly 10 years ago this month.

    The case of Nicolas Perruche gave rise to a national debate in France over compensation for serious consequences of medical error. Ultimately, legislation was enacted banning the cause of action known in Anglo-American law as wrongful life, and an agency was established to adjudicate subsequent claims. As other developed nations continue to wrestle with rapid increases in the cost of professional liability coverage and health care in general, a review of the Perruche case and its influence on French health policy may advance the discussion beyond the current stalemate of hardened advocacy positions.

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

    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.

  14. Music, Mechanism, and the "Sonic Turn" in Physical Diagnosis.

    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.

    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).

    The dishwasher died after faithfully serving the household for over seventeen years. One would expect a MacGyver treasure trove of parts to be found inside. Here, we will present what could be salvaged from a dishwasher that could be of use to hydrological research. The dishwasher's demise was too close to the submission deadline to promise anything in detail but there will be pumps, valves, level sensors, temperature sensors and, perhaps, a turbidity sensor. In addition, there may be more generic parts of interest such as timers, transformers and heaters. What will be presented is a hydrology oriented anatomy lesson of a dishwasher that would make Dr. Nicolaes Tulp proud.

    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.

    During the 17th century, Mrs Fouquet who was the mother of the minister of Finances, Nicolas Fouquet, was a charitable Lady who prepared medicines and distributed these remedies to poor people. One of her sons, Louis, who was the bishop of Agde, decided to publish his mother's formulas. He asked his own doctor, named Delescure, to carry out the edition of the formulas he had collected from his mother. The book was first published in 1675, and it twas published again more than fifty times, until 1765. This book was very useful for charitable Ladies and clergymen who purchased poor people with medicines.

    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.

    Tight focusing of the laser pulses opens a possibility to modify the properties of transparent materials and create high-density memories and photonic crystals. It was demonstrated recently [1,2] a formation of sub-wavelength holes by focusing a 100 ns, 100 fs laser pulses inside samples of sapphir and glass. This paper presents the results of numerical simulations of the interaction of sub-ps laser pulses with transparent dielectrics. It contains two parts : a 2D model of the laser energy deposition, based on the solution of full Maxwell equations coupled to a ionisation model accounting for the multiphotonic and avalanche ionisation, and the 3-body recombination. The second part presents the 2D hydrodynamic simulations of the shock wave propagation and the cavity formation with initial conditions provided by 2D absorption model. It is shown that the cavity parameters are very sensitive to the properties of the EOS in the phase transition domain. [1] E.G. Gamaly, S. Juodkazis, K. Nishimura, H. Misawa, B. Luther-Davies, L.

    Five years of measurements from the Global Positioning System (GPS) satellites collected between 1986 and 1991 are used to investigate deformation in the offshore regions of southern California. GPS provides the first practical technique to make precise geodetic measurements in the region. The geodetic network is situated along the California coastline from Vandenberg (120.6 deg W, 34.6 deg N) to San Diego, with additional sites on Santa Cruz, San Nicolas, Santa Catalina, Santa Rosa, and San Clemente Islands. The precision of horizontal interstation vectors is subcentimeter, and the interstation vector rate between Owens Valley Radio Observatory (OVRO) and Vandenberg agrees with the very long baseline interferometry derived rate to within one standard deviation. No significant motion is observed in th e western Santa Barbara Channel between Vandenberg and Santa Rosa Island, 0.5 +/- 1.6 mm/yr, where the quoted uncertainties are one standard deviation. Motions in the eastern Santa Barbara Channel are consistent with compressional deformation of 6 +/- 1 mm/yr at N16 +/- 3 deg E. This motion is in agreement with seismicity and an independent geodetic analysis for the period 1971-1987 (Larsen, 1991). San Clemente Island is moving relative to San Diego at the rate of 5.9 +/- 1.8/yr at a direction of N38 +/- 20 deg W. The motion between San Nicolas Island and San Clemente Island, 0.8 +/- 1.5 mm/yr, is insignificant.

  6. Enhancement of Hydrophilic Characteristics of Non-Wetting Porous Substrates by Kaolinite Treatment

    2007-01-01

    The use of porous media has enormous potential for thermal management and phase separation in terrestrial, micro, Lunar and Marian gravity environments. Recently, a porous media based gravity insensitive condensing heat exchanger for humidity control has been proposed and successfully demonstrated by the authors. A strongly hydrophilic porous substrate is essential for condensing and trapping water vapor from the airstreams. However, most porous media which have good thermal characteristics are poorly wetting to water. This poses a significant obstacle in the development of the porous media based condensing heat exchanger. In response to this problem, a clay based process was developed for improving the wettability of non-wetting and partially wetting porous media. It was demonstrated that poorly wetting porous graphite as well as porous stainless steel could be converted to a completely wetting porous substrate by kaolinite treatment. The process enhances the wettability of both the surface and the interior pores. The paper presents experimental results of enhanced wettability of the treated substrate in terms of imbibition rate and capillary pressure as a function of saturation. The long term stability of the treated surface is also investigated and discussed.

    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.

    The emerging global epidemic of Alzheimer’s disease (AD) demands novel paradigms to address the two unmet needs of the field: (a) cost-effective health care delivery programs/services, and (b) clinical and basic research to accelerate therapy discovery/development. This report outlines a model demonstration project, the Marian S. Ware Alzheimer Program at the University of Pennsylvania, which was designed to achieve four specific aims: (1) improve the integration and continuity of AD care; (2) identify biomarkers that detect the earliest presence of AD and related neurodegenerative cognitive disorders; (3) enhance both the design and conduct of clinical trials as well as review their results to more effectively test new AD therapies and translate valuable therapies into clinical practice; and (4) discover and develop novel disease-modifying small molecule treatments for AD. The “Ware-UPenn” program has been presented in this report as a useful prototype for partnerships between private philanthropy and academia in planning and developing programs to address a major national public health problem.

    The Drell-Yan dilepton production at backward rapidities is studied in proton-nucleus collisions at Relativistic Heavy Ion Collider and LHC energies by comparing two different approaches: the k{sub T} factorization at next-to-leading order with intrinsic transverse momentum and the same process formulated in the target rest frame, i.e., the color dipole approach. Our results are expressed in terms of the ratio between p(d)-A and p-p collisions as a function of transverse momentum and rapidity. Three nuclear parton distribution functions are used: EKS (Eskola, Kolhinen, and Ruuskanen), EPS08, and EPS09 and, in both approaches, dileptons show sensitivity to nuclear effects, specially regarding the intrinsic transverse momentum. Also, there is room to discriminate between formalisms: the color dipole approach lacks soft effects introduced by the intrinsic k{sub T}. Geometric scaling GBW (Golec-Biernat and Wusthoff) and BUW (Boer, Utermann, and Wessels) color dipole cross section models and also a DHJ (Dumitru, Hayashigaki, and Jalilian-Marian) model, which breaks geometric scaling, are used. No change in the ratio between collisions is observed, showing that this observable is not changed by the particular shape of the color dipole cross section. Furthermore, our k{sub T} factorization results are compared with color glass condensate results at forward rapidities: the results agree at Relativistic Heavy Ion Collider although disagree at LHC, mainly due to the different behavior of target gluon and quark shadowing.

    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.

    The chimeric behavior of thioxanthone in protic solvents has been investigated employing computational chemistry methods. In particular, methanol and 2,2,2-trifluoroethanol have been chosen in this study. The solvent environment has been modeled using microsolvation in combination with a conductor-like screening model. The vertical excitation spectrum within the same solvent is seen to depend on the number of specific bonds formed between the chromophore and the solvent molecules. Two different models have been discussed in this work, namely, one and two H-bond models. In particular, the formation of the second H-bond causes the energy gap between the πHπL* and nOπL* states to increase further. Excited-state absorption spectra for the photophysically relevant electronic states have been theoretically determined for comparison with the time-resolved spectra recorded experimentally [Villnow, T.; Ryseck, G.; Rai-Constapel, V.; Marian, C. M.; Gilch, P. J. Phys. Chem. A 2014]. The equilibration of the 1(πHπL*) and 3(nOπL*) states holds responsible for the chimeric behavior. This equilibrium sets in with a calculated time constant of 23 ps in methanol and 14 ps in TFE (5 and 10 ps in experiment, respectively). The radiative decay from the optically bright 1(πHπL*) state is computed to occur with a time constant of 25 ns in both solvents (14–25 ns in experiment).

    The photophysics of thioxanthone (TX) dissolved in methanol (MeOH) and 2,2,2,-trifluoroethanol (TFE) was studied by time-resolved fluorescence and absorption spectroscopy. The spectrally integrated stimulated emission is seen to lose amplitude within ∼5-10 ps. This is much shorter than the fluorescence lifetimes of the compound (2.7 ns for MeOH and 7.6 ns for TFE). The initial reduction in amplitude is attributed to reversible intersystem crossing between the primarily excited (1)ππ* and a triplet (3)nπ* state. The latter one is energetically slightly (∼0.02 eV) above the former one. Addition of the quencher 1-methylnaphthalene (1-MN) reduces the fluorescence lifetime and yields triplet excited 1-MN, giving further evidence for the equilibrium of singlet and triplet excitations. The depopulation of these two states on the nanosecond time scale results in the rise of the lowest triplet state, a (3)ππ* state. Temperature dependencies attribute this to an activated internal conversion process between the two triplet states. Kinetic and energetic parameters derived from the experimental data will be compared with quantum chemical results in the accompanying paper [Rai-Constapel , V. , Villnow , T. , Ryseck , G. , Gilch , P. , and Marian , C.

    2016-09-01

    We study the effects of a parity-odd "odderon" correlation in Jalilian-Marian-Iancu-McLerran-Weigert-Leonidov-Kovner renormalization group evolution at high energy. Firstly we show that in the eikonal picture where the scattering is described by Wilson lines, one obtains a strict mathematical upper limit for the magnitude of the odderon amplitude compared to the parity-even Pomeron one. This limit increases with Nc, approaching infinity in the infinite Nc limit. We use a systematic extension of the Gaussian approximation including both two- and three-point correlations which enables us to close the system of equations even at finite Nc. In the large-Nc limit we recover an evolution equation derived earlier. By solving this equation numerically we confirm that the odderon amplitude decreases faster in the nonlinear case than in the linear Balitsky-Fadin-Kuraev-Lipatov limit. We also point out that, in the three-point truncation at finite Nc, the presence of an odderon component introduces azimuthal angular correlations ˜cos (n φ ) at all n in the target color field. These correlations could potentially have an effect on future studies of multiparticle angular correlations.

    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

    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.

  18. Computationally-efficient stochastic cluster dynamics method for modeling damage accumulation in irradiated materials

    2015-11-01

    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 procedure 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.

A thick and massive growth of benthic diatoms was covering or being entangled with a variety of common benthic megafauna such as stalked ascidians, sponges, tubedwelling polychaetes, gastropods, bryozoans, and others. This finding is an outcome of recent investigations on benthic communities in Marian Cove, King George Island, where glacier retreat has been proceeding quickly for the past several decades. Dominance of benthic diatoms during the austral summer has been frequently reported in shallow Antarctic nearshore waters, which in turn indicates their potential as a primary food item for secondary producers living in this harsh environment. However, previous blooming records of the benthic diatoms were primarily based on data from water column samples. We are the first to report observational evidence of shallow seafloor substrates, including the massive blooming of benthic diatoms and their associations with common benthic megafauna in an Antarctic fjord.

  20. Fractional Brownian motions: memory, diffusion velocity, and correlation functions

    Fractional Brownian motions (FBMs) have been observed recently in the measured trajectories of individual molecules or small particles in the cytoplasm of living cells and in other dense composite systems, among others. Various types of FBMs differ in a number of ways, including the strength, range and type of damping of the memory encoded in their definitions, but share several basic characteristics: distributions, non-ergodic properties, and scaling of the second moment, which makes it difficult to determine which type of Brownian motion (fractional or normal) the measured trajectory belongs to. Here, we show, by introducing FBMs with regulated range and strength of memory, that it is the structure of memory which determines their physical properties, including mean velocity of diffusion; therefore, the course and kinetics of several processes (including coagulation and some chemical reactions). We also show that autocorrelation functions possess characteristic features which enable identification of an observed FBM, and of the type of memory governing its trajectory.

  1. Subleading-N corrections in non-linear small-x evolution

    We explore the subleading- N corrections to the large- N Balitsky-Kovchegov (BK) evolution equation by comparing its solution to that of the all- N Jalilian-Marian-Iancu-McLerran-Weigert-Leonidov-Kovner (JIMWLK) equation. In earlier simulations it was observed that the difference between the solutions of JIMWLK and BK is unusually small for a quark dipole scattering amplitude, of the order of 0.1%, which is two orders of magnitude smaller than the naively expected 1/Nc2≈11%. In this paper we argue that this smallness is not accidental. We provide analytical arguments showing that saturation effects and correlator coincidence limits fixed by group theory constraints conspire with the particular structure of the dipole kernel to suppress subleading- N corrections reducing the difference between the solutions of JIMWLK and BK to 0.1%. We solve the JIMWLK equation with improved numerical accuracy and verify that the remaining 1/N corrections, while small, still manage to slow down the rapidity-dependence of JIMWLK evolution compared to that of BK. We demonstrate that a truncation of JIMWLK evolution in the form of a minimal Gaussian generalization of the BK equation captures some of the remaining 1/N contributions leading to an even better agreement with JIMWLK evolution. As the 1/N corrections to BK include multi-reggeon exchanges one may conclude that the net effect of multi-reggeon exchanges on the dipole amplitude is rather small.

    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.

  3. English Medieval Churches, 'Festival Orientation' and William Wordsworth

    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.

  4. Influence of Wind and Dissipation on the Modulational Instability

    2010-05-01

    Among phenomena explaining the occurrence of rogue waves, the modulational instability is considered to be of major importance (Kharif & Pelinvosky (2003)). This instability corresponds to the nonlinear evolution of Stokes waves travelling in infinite depth, in the presence of perturbations. While no dissipation is considered, the nonlinear wave train encounters a series of modulation-demodulation cycles, called the Fermi-Pasta-Ulam recurrence phenomenon. Segur et al. (2005) revisited the Benjamin-Feir instability when dissipation is taken into account. These authors showed analytically and experimentally, within the framework of Nonlinear Schrodinger equation, that for waves with narrow bandwidth and moderate amplitude, the presence of dissipation stabilizes the modulational instability in the sense of Lyapunov. In the space of wavenumbers, the region of instability shrinks as time increases. As a result, any initially unstable mode of perturbation would finally become stable. This results were later confirmed by fully nonlinear simulations conducted by Wu, Liu & Yue (2006). These results would question the role of modulational instability on the generation of freak waves in open seas. In a recent work, Kharif et al. (2010) revisited analytically Segur's approach, studying the effect of wind on the result described above. Within the framework of the nonlinear Schrodinger equation, they derived a new marginal stability criterion and showed that the modulational instability of the wave group depends on both the frequency of the carrier wave and the strength of the friction velocity (or the wind speed). They gave for fixed values of water surface roughness the marginal curves separating stable states from unstable states. As a result, the occurrence of modulational instability would be possible in open seas. In this work, we investigate numerically this new marginal stability criterion. The fully nonlinear behavior of the wave train and modulation are simulated

These primary processes not only lead to N+ molecular 2 monocations but also to N+ atomic ions and to N2+ molecular dications, which can 2 pertain some internal or translational excitation. This contribution will summarize our efforts to caracterize in gaz phase laboratory experiments the reactivity of the nitrogen ions with the most important neutral targets of the Titan's atmosphere [1-3]: • N+ + CH4 , C2 H2 , and C2 H6 2 • N+ (3 P, 1 D) + CH4 , and C2 H4 • N2+ + N2 , CH4 , and C2 H4 2 In this work, particular attention has been paid on the effect of internal and/or translational excitation of the primary nitrogen ions on the rate constant and branching ratio of these ion-molecule reactions. The results from these studies have been compared to the literature values when available and some significant differences have been found. These new values have been used as input data in 1D models of the Titan's ionosphere to show the effect on the final density profiles of the main ions [4] and to demonstrate the existence of a N2+2 dication

  6. Hydrates in the California Borderlands: 2D CSEM inversion results from towed and seafloor arrays

    Methane hydrate, an ice-like solid clathrate of methane and water, forms in shallow continental slope sediments, and is both a potential energy source and geologic hazard. Traditionally, methane hydrate presence is inferred from a seismically detected bathymetry tracking velocity inversion, known as the bottom-simulating reflector (BSR). However the BSR is an indicator of free gas at the base of the hydrate stability zone, and not an indicator of hydrate. As such, seismic methods are limited in their capacity to identify and quantify hydrate presence and concentration. Controlled source electromagnetic (CSEM) methods are sensitive to, and are able to directly detect, the presence of electrically resistive methane hydrate and free gas. Additionally, because shallow resistors can mimic deeper resistors in seafloor instruments, understanding the shallow sediment structure can inform deeper crustal modeling. We conducted two CSEM surveys in the San Nicolas Basin, located 150km west of San Diego where a BSR was identified from legacy seismics. Both surveys were conducted using a deep-towed EM transmitter followed by 4 towed 3-axis electric field receivers spaced every 200 m from 400-1000 m behind the transmitter. Either a half-hertz or quarter-hertz modified square wave was transmitted on a 200 ampere, 100 m dipole that was flown between 50 and 100m above the seafloor. The short transmitter-receiver offset allows resolution of shallow structure (less than 1km below seafloor), while the longer transmitter-seafloor receiver resolves deeper structure. Between the two surveys, 27 seafloor receivers were deployed and ~150km of lines were towed, including 5 transects of the basin coincident with legacy seismic lines, and a short-offset repeatability study. Initial 1D modeling showed the presence of a resistor coincident with the BSR. Further 2D inversions using the MARE2DEM inversion program were run for the towed array. These inversions show a 4 ohm-m resistor in the central

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

    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.

    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

    In the section "Is there any evidence that lichenometry works?" in our paper we claim that Young et al. (2009) incorrectly transcribed a lichen growth curve from Solomina and Calkin (2003), when they used it in the Alaska Range. The error is actually ours, as we based that point of discussion on the Brooks Range curve from Solomina and Calkin (2003) rather than the central Alaska curve that Young et al. actually used. There was no erroneous transcription, and we apologize to Nicolas Young and his coauthors. The last sentence in the paragraph in question should read "We conclude that the correspondence of 10Be ages and lichenometric ages in this case is a stroke of lucky coincidence".

  12. A Logical Process Calculus

    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.

  13. The Surprising History of Claims for Life on the Sun

    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.

    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.

    The non-equilibrium plasma of diffuse coplanar surface barrier discharge (DCSBD) was tested for decontamination of bacteria Escherichia coli on polymer surfaces. We investigated the optical parameters of DCSBD plasma generated in synthetic air with different relative humidity. Our study was provided to estimate the main plasma components active during the DCSBD plasma degradation of E. coli contamination prepared on polytetrafluoroethylene (PTFE, Teflon) surface, in ambient air at atmospheric pressure. The DCSBD plasma was characterized by means of electrical measurements and optical emission spectroscopy. The inactivation of E. coli bacteria was evaluated by standard microbiological cultivation (CFU plate counting). The experimental results of the germicidal efficiency obtained for short plasma exposure times proved the effectiveness of DCSBD plasma for the polymer surface decontamination.

    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.

    Inversion of gravity data is one of the important steps in the interpretation of practical data. One of the most interesting geological frameworks for gravity data inversion is the detection of sharp boundaries between orebody and host rocks. The focusing inversion is able to reconstruct a sharp image of the geological target. This technique can be efficiently applied for the quantitative interpretation of gravity data. In this study, a new reweighted regularized method for the 3D focusing inversion technique based on Lanczos bidiagonalization method is developed. The inversion results of synthetic data show that the new method is faster than common reweighted regularized conjugate gradient method to produce an acceptable solution for focusing inverse problem. The new developed inversion scheme is also applied for inversion of the gravity data collected over the San Nicolas Cu-Zn orebody in Zacatecas State, Mexico. The inversion results indicate a remarkable correlation with the true structure of the orebody that is achieved from drilling data.

    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 -- 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.

  1. The impact of in vitro digestion on bioaccessibility of polyphenols from potatoes and sweet potatoes and their influence on iron absorption by human intestinal cells.

    2013-11-01

    The composition of potatoes as determined by chemical extraction has been described extensively. It is thus quite well known that, among other compounds, potato is rich in polyphenols, vitamins and in some minerals. This paper underlines the important role of simulated gastro-intestinal in vitro digestion in the bioaccessibility of polyphenols (chlorogenic acid and derivatives, and rutin) from potatoes and sweet potatoes and their impact on iron uptake. Concentrations of polyphenols in the flesh of two potato cultivars (Nicola, white potato, and Vitelotte, purple potato) and sweet potato were measured by Ultra Performance Liquid Chromatography after boiling and after in vitro digestion. Chemical extraction underestimates polyphenol amounts that can be released during digestion and that are actually bioaccessible. Iron uptake, as evaluated by a ferritin assay, by intestinal human cells was decreased after incubation with the intestinal phase of in vitro digestion, presumably due to the presence of polyphenols.

    Effect of four simple organic acids water solution on a DC diaphragm discharge was studied. Efficiency of the discharge was quantified by the hydrogen peroxide production determined by UV-VIS spectrometry of a H2O2 complex formed with specific titanium reagent. Automatic titration was used to study the pH behaviour after the plasma treatment. Optical emission spectroscopy overview spectra were recorded and detailed spectra of OH band and Hβ line were used to calculate the rotational temperature and comparison of the line profile (reflecting electron concentration) in the acid solutions.

    Ground based radiometer measurements at 20.6, 31.65, and 90.0 GHz were analyzed to provide attenuation statistics, thus extending the data base of previous NAPEX studies. Using data from colocated radiosondes, comparisons of measurements and calculations of brightness temperatures are presented. The oxygen absorption model of Rosenkranz and the water vapor absorption models of Liebe and of Waters are used. Data from July 1987 at San Nicolas Island, California and from December 1987, August and November 1988 at Denver, Colorado, are included. Joint attenuation statistics at 20.6 and 31.65 GHz are presented for two locations of the Colorado Research Network for December 1987 and August 1988.

    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 development of the Neurociencias in the Spain at the first third of the 20th century had a strong histological and pathological component. The work of Santiago Ramon and Cajal and Luis Simarro was continued by some excellent disciples: Nicolas Achúcarro, Gonzalo Rodriguez Lafora, Fernando de Castro, etc. Some of them had to make compatible diverse occupations, even the professional exercise of psychiatry, before obtaining a modest - but stable - position of investigation. In spite of some misalignments in the institutional development of the centers and the personal biographical ups and downs, the Junta para Ampliación de Estudios was the great institution that fomented the international formation of the investigators and equipped to them with the means to develop its work.

    A canvas painting by Milo Milunović "The Inspiration of the poet" was studied by energy dispersive X-Ray fluorescence (EDXRF), micro-Raman and Fourier transform infrared (FTIR) spectroscopy in order to identify materials used by the artist and his painting technique. Study is perfomed combining in situ non-destructive method with the preparation and study of cross-section samples and raw fragments of the samples. Milo Milunović, an eminent painter from Balkan region, made a copy of the Nicolas Poussin's original painting in Louvre in 1926/27. Obtained results revealed following pigments on the investigated canvas painting: vermilion, minium, cobalt blue, ultramarine, lead white, zinc white, cadmium yellow, chrome-based green pigment and several earth pigments - red and yellow ocher, green earth and umber. Ground layer was made of lead white mixed with calcium carbonate.

    We analyzed 790 Aedes aegypti from 14 localities of Mexico in 2009 to update information on the frequency of the Ile1016 allele in the voltage-gated sodium channel gene that confers resistance to pyrethroids and DDT. The Ile1016 mutation was present in all 17 collections, and was close to fixation in Acapulco (frequency = 0.97), Iguala (0.93), and San Nicolas (0.90). Genotypes at the 1016 locus were not in Hardy-Weinberg proportions in collections from Panuco, Veracruz, Cosoleacaque, Coatzacoalcos, Tantoyuca, and Monterrey due in every case to an excess of homozygotes. The high frequencies of this mutation in Ae. aegypti are probably due to selection pressure from pyrethroid insecticides, particularly permethrin, which has been used in mosquito control programs for >10 years in Mexico.

    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.

    The article reconstruct the situation of Italian psychiatry around 1930, using as unusual sources the pages of the Enciclopedia Italiana di Scienze, Lettere e Arti. This important work, conceived in 1925 and finished in 1937, is due - as well known - to the strong interest of Giovanni Gentile and to his capacity to involve in the project a great part of Italian intellectual world, without any ideological preclusion. The section devoted to Medical Sciences, including Psychiatry, was directed by Nicola Pende (1880-1970) and Giacinto Viola (1870-1943). A prevalent positivistic approach to science is well testified by their specific attention to preventive and social medicine, researches in Genetics and in biotypological constitutions. Psycopathological and psycological lemmas are very limited, underlying the medical disinterest towards contemporary philosophy and psycology.

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

    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.

  11. Role of inertia in the rheology of amorphous systems: A finite-element-based elastoplastic model.

    2016-02-01

    A simple finite-element analysis with varying damping strength is used to model the athermal shear rheology of densely packed glassy systems at a continuum level. We focus on the influence of dissipation on bulk rheological properties. Our numerical studies, done over a wide range of damping coefficients, identify two well-separated rheological regimes along with a crossover region controlled by a critical damping. In the overdamped limit, inertial effects are negligible and the rheological response is well described by the commonly observed Herschel-Bulkley equation. In stark contrast, inertial vibrations in the underdamped regime prompt a significant drop in the mean-stress level, leading to a nonmonotonic constitutive relation. The observed negative slope in the flow curve, which is a signature of mechanical instability and thus permanent shear banding, arises from the sole influence of inertia, in qualitative agreement with the recent molecular dynamics study of Nicolas et al., Phys. Rev. Lett. 116, 058303 (2016).

    Die Reinraumtechnik ist heute ein unverzichtbarer Bestandteil bei der Fertigung von Produkten der Life Sciences, den Bereichen Pharma, Lebensmittel, Kosmetik und Medizintechnik. In Anbetracht der langen Historie der Medizintechnik ist sie jedoch eine sehr junge Disziplin. 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].

    Results of experimental investigation of a volume-surface barrier discharge in a three-electrode system under periodic impulse voltage applied to the surface discharge (SD) electrodes and a d.c. potential applied to an additional third electrode are presented. It is shown that there is a strong influence of polarity and amplitude of the d.c. potential on the direct current "extracted" out of the surface discharge plasma layer by electric field of the third electrode. The amount of charged positive species that constitute the "extracted" current prevails under positive impulse voltage for low values of the negative d.c. potential of the third electrode. The amount of negative species prevails with higher values of the positive d.c. positive of the third electrode.

    2001-12-01

    Subsurface flow through the soil and deeper sediments of the riparian zone is known to be of crucial importance to denitrification and other nitrogen cycling processes. Since denitrification potential generally increases towards the soil surface, water table elevation can control the degree to which nitrate reduction is optimised. This paper presents data collected as part of a pan-European study of nitrate buffer zones, the NICOLAS project (Nitrogen Control by Landscape Structures in Agricultural Environments). An identical experimental design was employed at each site, allowing climatic controls on hydrology and nitrogen cycling processes to be explored. Nitrate elimination occurred at most of the 13 study sites spread out within Europe (between latitude 40\\deg and 55\\deg N) with an efficiency ranging from 5 to 30% of N concentration abatement per metre. This elimination usually occurred within the first few tens of metres at the upland-wetland interface depending on local geomorphological and hydrological conditions.

    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.

    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.

  18. Upper crustal structure and Neogene tectonic development of the California continental borderland

    1998-01-01

    Multichannel seismic-reflection data, sonobuoy seismic-refraction data, and regional geology are used to define the upper crustal structure of the southern California continental borderland and to delineate the characteristics of the main lithotectonic belts of the region. The Catalina Schist belt is separated on its west side from the gently deformed Nicolas forearc belt by faults that have steep west dips and pronounced normal separations. On its east side the schist belt is bounded by alarge detachment fault that dips gently to the east beneath the west edge of the Peninsular Ranges belt at the coastline near Oceanside. The Catalina Schist was uplifted from middle crustal depths and exposed during a major event of extensional tectonism that started in early Miocene time in conjunction with about 10?? of clockwise rotation of the western Transverse Ranges belt. Part of the uplift of the Catalina Schist could have occurred on the detachment fault, but it is through to have mostly occurred on the steep faults that bound the west edge of the schist belt. A large amount of uplift is required, and it probably involved strong footwall flexural deformation in the wake of the translating and rotating western Transverse Ranges and Nicolas forearc belts. Extension, accompanied by probable large amounts of right slip, continued in the borederland region during and after middle Miocene time. The later stage of extension was accompanied by rapid clockwise rotation of the western Transverse Ranges of at least 90??. Most of the borderland, including the belt of schist that was uplifted in early Miocene time, was further deformed into numerous basins and ridges during this stage of oblique extension. The primary driving force for the deformation is thought to have been derived from the rapid northwest motion of the Pacific plate after it had become coupled to the Farallon plate system, which had previously been subducted beneath the borderland.

    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 spring 2016 mainland sea otter count began on 1 May and was completed on 11 May. Overall viewing conditions this year were very good, being more favorable than those during the 2015 spring census (3.1 vs. 2.6, where 0=poor, 1=fair, 2=good, 3=very good, and 4=excellent) and contributed to the relatively short duration of the count. The surface canopies of kelp (Macrocystis sp.) were considered by most participants to be below normal for this time of year in the northern half of the range and about normal in the southern half. Sea otters along the mainland were surveyed (using a combination of ground-based and aerial-based surveys) from Pillar Point in San Mateo County in the north, to Rincon Point in the south at the Santa Barbara/Ventura County line. A separate ground-based survey of the sea otter population at San Nicolas Island was completed earlier (April 15-April 18). Surface kelp canopies at the time of survey at San Nicolas Island were estimated to be below normal near shore off the western end of the island and about normal elsewhere.  Survey viewing conditions were very good (View Score = 3.0).These data support the following data series release: Tinker, M.T., and Hatfield, B.B., 2016, California sea otter (Enhydra lutris nereis) census results, spring 2016: U.S. Geological Survey Data Series 1018, 10 p., http://dx.doi.org/10.3133/ds1018.

    The seismic wave is translated to T-wave when earthquakes occur below seafloor with a traveling speed of 1500 m/s in the SOFAR channel which centers roughly at 1000 m water depths (Tolstoy and Ewing, 1950). Many studies have shown that hydrophone can be set up in the SOFAR channel to collect acoustic data to investigate plate movement (Fox and Dziak, 1999), seismisity (Fox et.al, 2001), characteristic of T-wave (Park et.al, 2001), seafloor volcanism (Nicolas, 1989), among others. Institute of Earth Sciences of Academia Sinica has been collaborating with Taiwan Ocean Research Institute (TORI) and the Institute of Undersea Technology (IUT) of the National Sun Yat-sen University (NSYSU) to succefully build a new wide-band OBS (Yardbird). We hope that Yardbird is not only an OBS but also a multi-function underwater recording plotform. Therefor we are developing a low-power consumption, inexpensive hydrophone to catch acoustic signals. The protoypte of it has passed a series of tests and got some seismic seafloor data. This paper describes the design goal of hydrophone, component specifications, field data analyzed, and discusses the future directions of instrument development.

    The usual Landau level quantization, as demonstrated in the 2D quantum Hall effect, is crucially based on the planar structure. In this talk, we explore its 3D counterpart possessing the full 3D rotational symmetry as well as the time reversal symmetry. We construct the Landau level Hamiltonians in 3 and higher dimensional flat space for both relativistic and non-relativistic fermions. The 3D cases with integer fillings are Z2 topological insulators. The non-relativistic version describes spin-1/2 fermions coupling to the Aharonov-Casher SU(2) gauge field. This system exhibits flat Landau levels in which the orbital angular momentum and the spin are coupled with a fixed helicity. Each filled Landau level contributes one 2D helical Dirac Fermi surface at an open boundary, which demonstrates the Z2 topological nature. A natural generalization to Dirac fermions is found as a square root problem of the above non-relativistic version, which can also be viewed as the Dirac equation defined on the phase space. All these Landau level problems can be generalized to arbitrary high dimensions systematically.

    The goals of the current study were to examine whether (a) negative events mediate the relationship between materialism and risky behavior engagement and (b) materialism moderates the relationship between stress and engagement in risky behaviors in Chinese youth. At Time 1, 406 adolescents (ages 14-19) from Yue Yang, China, completed measures assessing engagement in risky behaviors and the occurrence of negative events. Follow-up assessments occurred once a month for 6 months. In line with our hypotheses, results of hierarchical linear modeling analyses indicated that higher levels of negative events mediated the relationship higher levels of materialism and greater risky behavior engagement. In addition, adolescents who exhibited higher levels of materialism were more likely than adolescents possessing lower levels of materialism to report increased engagement in risky behaviors in response to negative life events. At the same time, the effect was only present in boys. Unexpectedly, girls who reported lower levels of materialism also exhibited increased engagement in risky behaviors in response to negative events.

High Alt Med Biol 16:43–51, 2015—Portulaca oleracea L. (PO) is known as “a vegetable for long life” due to its antioxidant, anti-inflammatory, and other pharmacological activities. However, the protective activity of the ethanol extract of PO (EEPO) against hypoxia-induced pulmonary edema has not been fully investigated. In this study, we exposed mice to a simulated altitude of 7000 meters for 0, 3, 6, 9, and 12 h to observe changes in the water content and transvascular leakage of the mouse lung. It was found that transvascular leakage increased to the maximum in the mouse lung after 6 h exposure to hypobaric hypoxia. Prophylactic administration of EEPO before hypoxic exposure markedly reduced the transvascular leakage and oxidative stress, and inhibited the upregulation of NF-kB in the mouse lung, as compared with the control group. In addition, EEPO significantly reduced the levels of proinflammatory cytokines and cell adhesion molecules in the lungs of mice, as compared with the hypoxia group. Our results show that EEPO can reduce initial transvascular leakage and pulmonary edema under hypobaric hypoxia conditions. PMID:25761168

    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.

    The red swamp crayfish has become one of the most important freshwater aquaculture species in China. At present, although it is widely distributed in the middle and lower reaches of the Yangze River basin, little is known about its population genetics and geographic distribution in China. We estimated the genetic diversity among 6 crayfish populations from 4 lakes (Hongze Lake, Poyang Lake, Dongting Lake, and Yue Lake) using AFLPs. A total of 129 loci were generated with 5 EcoRI-MseI primer combinations and scored as binary data in 139 individuals. These data were analyzed by cluster methods with the NTSYSpc software package. The 6 populations were separated into 3 major clusters by principal coordinate analysis and cluster analysis. Among the 6 populations, the highest gene diversity was found within the Nanjing population. Analysis of molecular variance demonstrated that most variation occurred within populations (91.20%). The estimated average GST value across all loci was 0.4186, suggesting (very) low gene flow among the different localities. We conclude that there is high genetic differentiation among crayfish in the middle and lower reaches of the Yangze River. This information will help in the selection of high-quality individuals for artificial reproduction.

    The fluctuating CDK-CYCLIN complex plays a general role in cell-cycle control. Many types of stem cells use unique features of the cell cycle to facilitate asymmetric division. However, the manner in which these features are established remains poorly understood. The cell cycle of Drosophila female germline stem cells (GSCs) is characterized by short G1 and very long G2 phases, making it an excellent model for the study of cell cycle control in stem cell fate determination. Using a Drosophila female GSCs model, we found Gcn5, the first discovered histone acetyltransferase, to maintain germline stem cells in Drosophila ovaries. Results showed that Gcn5 is dispensable for the transcriptional silencing of bam, but interacts with Cyclin A to facilitate proper turnover in GSCs. Results also showed that Gcn5 promotes Cyclin A ubiquitination, which is dependent on its acetylating activity. Finally, results showed that knockdown of Cyclin A rescued the GSC-loss phenotype caused by lack of Gcn5. Collectively, these findings support the conclusion that Gcn5 acts through acetylation to facilitate Cyclin A ubiquitination and proper turnover, thereby determining the fate of GSCs.-Liu, T., Wang, Q., Li, W., Mao, F., Yue, S., Liu, S., Liu, X., Xiao, S., Xia, L.

    "Danxi Theory" had deep influence on the traditional medicine in Korea and Japan. In Korea, the compilation of Yi Fang Lei Ju and Dong Yi Bao Jian referred to the medical works of ZHU Danxi and that of his students, the Korean doctors advocated the theory of ZHU Danxi's theory of "four injuries by qi, blood, phlegm and stagnation", and quoted large number of formulas and herbs from Dangxi's works into the above books. In Japan, Tashiro Sanki had came to China and studied medicine from Japanese monk Yue Hu, who was the disciple of YU Tianmin (a private disciple of ZHU Danxi). After returned to Japan he energetically initiated Danxi's theory and classified diseases to blood disease, qi disease and phlegm disease (water toxin) according to Danxi's theory of "four injuries by qi, blood, phlegm and stagnation". His student Manase Dōsan set up a "Danxi Society" and spread Danxi Theory in Japan and therefore the unique medical system "Gose Ha shcool" was formed. His student Manase Gensaku, and Manase Gensaku's students Okamoto Genya, Nagasawa Doju and Hurubayashi Kengi spread and developed Danxi Theory, hich was popular in Japan for more than 200 years. It was proved that Danxi Theory had deep and far influence on the formation and development of overseas traditional medicine in Korea and Japan.

    In our recent paper [C. Hermansen, J. C. Mauro, and Y.-Z. Yue, J. Chem. Phys. 140, 154501 (2014)], we applied temperature-dependent constraint theory to model the glass transition temperature (Tg) and liquid fragility index (m) of alkali phosphate glasses. Sidebottom commented on this paper concerning the m values obtained by differential scanning calorimetry (DSC) [D. L. Sidebottom, J. Chem. Phys. 142, ⬛ (2015)]. We have considered Sidebottom's comments carefully and conclude that the m values of phosphate liquids obtained by DSC are reliable, except for the NaPO3 and possibly P2O5 compositions. Based on his dynamic light scattering measurements, Sidebottom has found that P2O5 is a strong liquid with m ≈ 20. However, based on the heat capacity jump at Tg and the stretching exponent of the relaxation function, P2O5 should be classified as an intermediate fragile liquid with m ≈ 40. We also argue that m cannot be universally related to the average connectivity of the network and point out several inconsistencies with this view.

    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.

    Ca2+-activated chloride channels encoded by TMEM16A and 16B are important for regulating epithelial mucus secretion, cardiac and neuronal excitability, smooth muscle contraction, olfactory transduction, and cell proliferation. Whether and how the ubiquitous Ca2+ sensor calmodulin (CaM) regulates the activity of TMEM16A and 16B channels has been controversial and the subject of an ongoing debate. Recently, using a bioengineering approach termed ChIMP (Channel Inactivation induced by Membrane-tethering of an associated Protein) we argued that Ca2+-free CaM (apoCaM) is pre-associated with functioning TMEM16A and 16B channel complexes in live cells. Further, the pre-associated apoCaM mediates Ca2+-dependent sensitization of activation (CDSA) and Ca2+-dependent inactivation (CDI) of some TMEM16A splice variants. In this review, we discuss these findings in the context of previous and recent results relating to Ca2+-dependent regulation of TMEM16A/16B channels and the putative role of CaM. We further discuss potential future directions for these nascent ideas on apoCaM regulation of TMEM16A/16B channels, noting that such future efforts will benefit greatly from the pioneering work of Dr. David T. Yue and colleagues on CaM regulation of voltage-dependent calcium channels. PMID:26083059

    Gelao ethnic group, an aboriginal population residing in southwest China, has undergone a long and complex evolutionary process. To investigate the genetic structure of this ancient ethnic group, mitochondrial DNA (mtDNA) polymorphisms of 102 Gelao individuals were collected and analyzed in this study. With the aid of the information extracted from control-region hypervariable segments (HVSs) I and II as well as some necessary coding-region segments, phylogenetic status of all mtDNAs under study were determined by means of classifying into various defined haplogroups. The southern-prevalent haplogroups B, R9, and M7 account for 45.1% of the gene pool, whereas northern-prevalent haplogroups A, D, G, N9, and M8 consist of 39.2%. Haplogroup distribution indicates that the Gelao bears signatures of southern populations and possesses some regional characters. In the PC map, Gelao clusters together with populations with Bai-Yue tribe origin as well as the local Han and the Miao. The results demonstrate the complexity of Gelao population and the data can well supplement the China mtDNA database.

    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.

    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.

    We present a novel strategy for minimizing the numerical dispersion error in edge discretizations of the time-domain electric vector wave equation on square meshes based on the mimetic finite difference (MFD) method. We compare this strategy, called M-adaptation, to two other discretizations, also based on square meshes. One is the lowest order Nédélec edge element discretization. The other is a modified quadrature approach (GY-adaptation) proposed by Guddati and Yue for the acoustic wave equation in two dimensions. All three discrete methods use the same edge-based degrees of freedom, while the temporal discretization is performed using the standard explicit Leapfrog scheme. To obtain efficient and explicit time stepping methods, the three schemes are further mass lumped. We perform a dispersion and stability analysis for the presented schemes and compare all three methods in terms of their stability regions and phase error. Our results indicate that the method produced by GY-adaptation and the Nédélec method are both second order accurate for numerical dispersion, but differ in the order of their numerical anisotropy (fourth order, versus second order, respectively). The result of M-adaptation is a discretization that is fourth order accurate for numerical dispersion as well as numerical anisotropy. Numerical simulations are provided that illustrate the theoretical results.

Hence, deciphering of these argots could help to understand and apply these prescriptions correctly.

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

    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

    The formation of a hot corona with the related escape rate of the oxygen atoms is an important issue affecting the evolution of the Marian atmosphere. While the dissociative recombination process appears to dominate the non-thermal escaping rate of the oxygen atoms, atmospheric sputtering by the re-impact of the pickup exospheric ions could have played a role in earlier epochs and at solar maximum in the present epoch. Due to the orientation of the interplanetary magnetic fields and the shielding of the crustal fields near Mar's surface, the pickup ions may re-impact the atmosphere with a variety of angles, energies, and spatial distributions. While night-side sputtering is suggested to occur based on modeling (Li et al., 2011), the sputter component due to pickup ion impacts on the oxygen corona can be distinguished from other ejection mechanisms, such as dissociative recombination. In preparation for the Maven mission, we performed a Monte Carlo model of the upper atmosphere coupled to a molecular dynamic calculation for the molecular collisions developed by Leblanc and Johnson (2002) to study the cascade sputtering effects in the region of the Martian exobase. Different incident angle and energy spectrum of the impact ions were tested. Further calculations with more realistic pickup ion impact distributions will be performed based on the numerical results of a 3D Monte Carlo Pickup Ion Transport model, which includes the electromagnetic backgrounds from the 3D multi-species MHD simulations (Y. Ma et al., 2004; Y. Ma and A. F. Nagy, 2007).

    Anatomy faculties are integral to basic science instruction in medical schools, particularly given the preponderance of anatomic instruction in the preclinical curriculum. Recent years have witnessed major curricular restructuring and other emerging national trends that pose significant challenges to anatomists. An examination of anatomy faculty perceptions at two philosophically distinct medical schools within this shifting climate provides an indicator of how different institutional characteristics may impact anatomy instruction and other faculty responsibilities. Semistructured interviews of anatomy faculty from a large, well-established allopathic medical school (Indiana University School of Medicine) and a small, new osteopathic medical school (Marian University College of Osteopathic Medicine) were explored using qualitative thematic analysis. Four overarching themes were identified: (1) Institutional philosophies, such as affiliation with osteopathic versus allopathic medicine, have minimal impact on how the anatomical sciences are taught. (2) Differences in anatomy faculty experiences at these two institutions are largely driven by the institution's size and history. There is a disparity between institutions in the relative importance of teaching and research, but an ability to do research is important for both faculties. (3) Anatomy instruction and research agendas are driven by personal philosophies and interests rather than institutional philosophy. (4) Autonomy is highly valued by anatomists at both institutions. All the participants share a devotion to educating future physicians. In fact, this study identified more similarities than differences in these two faculties. Finally, we argue that shared educational resources and research collaborations can improve anatomy education and faculty development at both institutions.

    The purpose of the Daemen Alternative Energy/Geothermal Technologies Demonstration Project is to demonstrate the use of geothermal technology as model for energy and environmental efficiency in heating and cooling older, highly inefficient buildings. The former Marian Library building at Daemen College is a 19,000 square foot building located in the center of campus. Through this project, the building was equipped with geothermal technology and results were disseminated. Gold LEED certification for the building was awarded. 1) How the research adds to the understanding of the area investigated. This project is primarily a demonstration project. Information about the installation is available to other companies, organizations, and higher education institutions that may be interested in using geothermal energy for heating and cooling older buildings. 2) The technical effectiveness and economic feasibility of the methods or techniques investigated or demonstrated. According to the modeling and estimates through Stantec, the energy-efficiency cost savings is estimated at 20%, or $24,000 per year. Over 20 years this represents $480,000 in unrestricted revenue available for College operations. See attached technical assistance report. 3) How the project is otherwise of benefit to the public. The Daemen College Geothermal Technologies Ground Source Heat Pumps project sets a standard for retrofitting older, highly inefficient, energy wasting and environmentally irresponsible buildings quite typical of many of the buildings on the campuses of regional colleges and universities. As a model, the project serves as an energy-efficient system with significant environmental advantages. Information about the energy-efficiency measures is available to other colleges and universities, organizations and companies, students, and other interested parties. The installation and renovation provided employment for 120 individuals during the award period. Through the new Center, Daemen will

    Kawasaki disease (KD) was first reported from Japan in 1967 by a young pediatrician, Tomisaku Kawasaki, while working at the Red Cross Hospital in Tokyo. Soon therafter, Marian Melish independently reported children with a similar clinical profile from Hawaii in the United States. KD has now been reported from all parts of the world, including several centers in India. Based on the epidemiology and clinical features, an infectious etiology has been suspected for long but no definitive causative agent has been implicated so far. Like many other vasculitides, the diagnosis of this condition is based on the recognition of a temporal sequence of clinical features, none of which is pathognomonic in isolation. KD is believed to be the commonest vasculitic disorder of children. Incidence rates as high as 60-150 per 100,000 children below 5 years of age have been reported from several countries. In India (as also perhaps in many other developing countries), however, majority of children with KD continue to remain undiagnosed probably because of the lack of awareness amongst pediatricians. The clinical features of KD can be confused with other common conditions like scarlet fever and the Stevens Johnson syndrome, if the clinician is not careful. Development of coronary artery abnormalities (CAA) is the hallmark of KD and accounts for most of the morbidity and mortality associated with the disease. Prompt recognition of the disease and early initiation of treatment with intravenous immunoglobulin (IVIG) results in significant reduction in the occurrence of CAA. It is, therefore, imperative for the pediatrician to diagnose and treat KD expeditiously. KD should be considered in the differential diagnosis of all febrile illnesses in young children where the fever persists for more than 5-7 days.

    Grids of recently released high-quality industry multichannel seismic (MCS) reflection data, combined with bathymetry and offshore well data are used to map digital 3D fault surfaces and stratigraphic reference horizons in the northern Continental Borderland offshore of southern California. This area experienced large-scale oblique crustal extension and translation associated with the initiation and development of the Pacific-North American plate boundary. The 3D surfaces of structure and stratigraphy can thus be used to better understand and evaluate regional patterns of uplift, subsidence, fault interaction and other aspects of plate boundary deformation. Our mapping in Santa Cruz basin and on Santa Rosa and Santa Cruz-Catalina Ridge reveals an unusual pattern of faulting, folding and basin subsidence. This subsidence is significant (up to 3-4 km since early-Miocene time) and is responsible for the development of several major Borderland basins. Vertical motions can be estimated from an early-Miocene unconformity that likely represents a paleo-horizontal, near-paleo-sea-level erosional surface. As such, it can be used to reconstruct Borderland forearc geometry prior to rifting, subsidence and subsequent basin inversion. Major findings to date include: (a) a better characterization of the complex 3D geometry and pinch-out of the eastern edge of the northern forearc Nicolas terrane and its implications for Borderland basin development, plate reconstructions, and vertical motions associated with oblique rifting; (b) recognition that the East Santa Cruz Basin fault, previously thought to be a predominantly high-angle, large- displacement right-slip fault representing the eastern edge of the Nicolas terrane, is in fact a series of reactivated right-stepping, NE-dipping reverse-separation faults; (c) discovery that NW-striking faults associated with Santa Cruz-Catalina Ridge bend west into a horse-tail structure to interact with and contribute to the southern frontal

    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.

    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

    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 plate 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%.

    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.

  11. Mesospheric airglow and ionospheric responses to upward-propagating acoustic and gravity waves above tropospheric sources

    The existence of acoustic waves (periods ~1-5 minutes) and gravity waves (periods >4 minutes) in the ionosphere above active tropospheric convection has been appreciated for more than forty years [e.g., Georges, Rev. Geophys. and Space Phys., 11(3), 1973]. Likewise, gravity waves exhibiting cylindrical symmetry and curvature of phase fronts have been observed via imaging of the mesospheric airglow layers [e.g., Yue et al., JGR, 118(8), 2013], clearly associated with tropospheric convection; gravity wave signatures have also recently been detected above convection in ionospheric total electron content (TEC) measurements [Lay et al., GRL, 40, 2013]. We here investigate the observable features of acoustic waves, and their relationship to upward-propagating gravity waves generated by the same sources, as they arrive in the mesosphere, lower-thermosphere, and ionosphere (MLTI). Numerical simulations using a nonlinear, cylindrically-axisymmetric, compressible atmospheric dynamics model confirm that acoustic waves generated by transient tropospheric sources may produce "concentric ring" signatures in the mesospheric hydroxyl airglow layer that precede the arrival of gravity waves. As amplitudes increase with altitude and decreasing neutral density, the modeled acoustic waves achieve temperature and vertical wind perturbations on the order of ~10s of Kelvin and m/s throughout the E- and F-region. Using a coupled multi-fluid ionospheric model [Zettergren and Semeter, JGR, 117(A6), 2012], extended for low-latitudes using a 2D dipole magnetic field coordinate system, we investigate acoustic wave perturbations to the ionosphere in the meridional direction. Resulting perturbations are predicted to be detectable by ground-based radar and GPS TEC measurements, or via in situ instrumentation. Although transient and short-lived, the acoustic waves' airglow and ionospheric signatures are likely to in some cases be observable, and may provide important insight into the regional

    The ubiquitin-proteasome and autophagy-lysosomal pathways are the two main routes of protein and organelle clearance in eukaryotic cells. The proteasome system is responsible for unfolded, short-lived proteins, which precludes the clearance of oligomeric and aggregated proteins, whereas macroautophagy, a process generally referred to as autophagy, mediates mainly the bulk degradation of long-lived cytoplasmic proteins, large protein complexes or organelles.(1) Recently, the autophagy-lysosomal pathway has been implicated in neurodegenerative disorders as an important pathway for the clearance of abnormally accumulated intracellular proteins, such as huntingtin, tau, and mutant and modified α-synuclein.(1-6) Our recent study illustrated the induction of adaptive autophagy in response to mutant glial fibrillary acidic protein (GFAP) accumulation in astrocytes, in the brains of patients with Alexander disease (AxD), and in mutant GFAP knock-in mouse brains.(7) This autophagic response is negatively regulated by mammalian target of rapamycin (mTOR). The activation of p38 MAPK by GFAP accumulation is responsible for mTOR inactivation and the induction of autophagy. We also found that the accumulation of GFAP impairs proteasome activity.(8) In this commentary we discuss the potential compensatory relationship between an impaired proteasome and activated autophagy, and propose that the MLK-MAPK (mixed lineage kinase-mitogen-activated protein kinase) cascade is a regulator of this crosstalk.

    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

    Acetone and ethanol extracts of carob (Ceratonia siliqua L.) leaf and pods were evaluated for their in vitro inhibitory ability against the pectinolytic Gram negative Pectobacterium atrosepticum (Pca, CFBP-5384) bacteria, the causal agent of potato soft rot. Potato (Solanum tuberosum, var nicola) tuber rot tissues obtained after 5 day bacterial inoculation was analyzed by LC-MS and GC-MS to study Pca pathogenicity. Trans/cis N-feruloylputrescine was identified in potato tuber after 5-day inoculation with Pca in a dark moist chamber. Although glycoalkoloid (α-chaconine and α-solanine) production increased due to Pca soft rot infection, it was not a resistance-determining factor. Many secondary metabolites were identified including the phytoalexins solavetivone and fatty acids responsible for plant defence responses. Acetone extract of carob leaf (FCA) exhibited the strongest inhibitory effect (IC50 = 1.5 mg/ml) and displayed synergistic antimicrobial effect in the presence of infected potato tuber extract (Pdt-Pca extract) against Pca. This synergy could be used in an integrated control program against potato soft rot pathogens, thereby reducing chemical treatments.

    We radiomarked 153 Xantus' Murrelets Synthliboramphus hypoleucus captured at sea near Santa Barbara Island (SBI), the largest murrelet colony in the California Channel Islands, USA. We tracked these radiomarked murrelets in the Southern California Bight (SCB) off coastal southern California during the 1995-97 breeding seasons. In 1995 during mild El Nino conditions, the murrelets were distributed in non-upwelling areas. In 1996-97, they were distributed in dense patches, aggregating in cool upwelled waters near the northern Channel Islands or south of San Nicolas Island. Murrelets flew longer distances from SBI to foraging areas in 1997 (x?? = 111 ?? 44 km) than in 1996 (x?? = 62 ?? 25 km), but the distances they travelled did not differ between months (Apr and May) within years. Mean foraging distances from SBI were similar for 'incubating' murrelets (determined on the basis of repeated visits to SBI) and 'non-incubating' murrelets during the colony attendance period. We attributed the low return rate of radiomarked murrelets to SBI to the capture and marking of a large proportion of birds that were not actively incubating rather than to any adverse effects of radio attachment. We believe changes in murrelet foraging patterns between the 1970s and 1990s are associated with changes in prey resources in the SCB. Flexibility in the foraging strategies of these murrelets may be related to the highly variable marine environment at the southern end of the California Current Upwelling System.

  16. Theorizing epigenesis in a time of preexistence: From the end of the seventeenth century to the 1720s.

    According to a classic periodization in the history of science, biological thought as it emerged in France from the last decades of the seventeenth century to the 1740s was strongly committed to the doctrine of the preexistence of germs. Nicolas Malebranche's role in disseminating this paradigm, particularly in the milieu of the Académie Royale des Sciences during the years when Bernard Le Bouyer de Fontenelle was its secretary, has been studied in detail, especially by Jacques Roger. However, much less has been said about the authors who argued against this doctrine prior to the appearance of the relevant pieces by Pierre-Louis Moreau de Maupertuis, Georges-Louis Leclerc, Comte de Buffon, and Denis Diderot. I aim to examine a series of French medical treatises and clandestine manuscripts that outlined a mechanist theory of epigenesis, between the end of the seventeenth century and the 1720s, to bring to light the strategies-often quite original-that allowed them to achieve this result. One interesting case is the heterodox readers of Malebranche, which use some of his own arguments (notably on the physiology of brain traces and the laws of nature) both against preexistence and to support epigenesis. I inquire into the historical worth of the positions defended by these authors as well as into the connections existing between the history of epigenesis and that of materialism in the early modern era.

    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

    2016-06-07

    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.

    To face the worldwide problem of anthropogenic carbon dioxide (CO2) emission new techniques have to be developed. One approach for carbon capture utilization (CCU) is the conversion of CO2 to more valuable chemicals, e.g., carbon monoxide (CO) by means of non-thermal plasma generated at ambient conditions and supplied by excess energy from renewable sources. This paper reports about the effect of the admixture of inert gases, namely nitrogen or argon to CO2 in a coplanar dielectric barrier discharge (DBD). Systematic experiments were conducted to investigate the effects of applied voltage, frequency, flowrate and CO2 concentration in the influent. The composition of products, energy efficiency and yield were determined. Within the investigated parameter ranges, the maximum conversion of CO2 to CO efficiency of 1% was achieved when the specific input energy was 190 J L-1, whereas the maximum CO yield of 0.7% was achieved when the specific input energy was 210 J L-1. In conclusion, the energy efficiency can be significantly increased by operating the plasma in a diluted CO2 gas.

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.

    This paper is a preliminary study intended to straighten out the role of reactive oxygen species in the activation mechanisms occurring in a plasma driven catalysis process for acetaldehyde decomposition. For this purpose, the interaction between the surface, the pollutant and one of the main oxidative species generated by non-thermal plasma, namely ozone, was studied. Acetaldehyde catalytic ozonation over a nanostructured Ag/TiO2/SiO2 catalyst is carried out at room temperature and atmospheric pressure, and followed by diffuse reflectance infrared fourier transform spectroscopy (DRIFTS). For this, the catalyst is firstly saturated with acetaldehyde. At the end of the saturation, acetaldehyde and crotonaldehyde, its condensation product, are identified as the major adsorbed species. In a second step, the surface ozonation is carried out and three additional intermediates are identified, namely, acetone, formic acid and acetic acid. Gaseous CO, CO2, methyl formate and methyl acetate are detected at the DRIFTS outlet, evidencing the partial mineralization of the adsorbed species. A global reaction scheme is proposed for explaining the formation of those adsorbed intermediates and gaseous products. This proposed heterogeneous ozone induced chemistry has to be taken into account when associating non-thermal plasma in air to a catalyst.

    The Transits of Venus of 1761 and 1769 were widely anticipated, due to the efforts of Edmond Halley and Joseph-Nicolas Delisle in promoting observations to determine solar parallax. Extensive planning resulted in widespread participation; with at least 110 different observing stations stations worldwide for one or both of the events. Results from the 1761 expeditions derived solar parallax measurements between 8.28 and 10.60 arc seconds. The 1769 results were much better, 8.43 to 8.80 arc seconds, as compared with the accurate value of 8.79 arc seconds. This presentation will note the efforts of Halley, Delisle, and James Ferguson in promoting scientific observation of the transit. The poster will include the observations of Thorbern Bergman at Uppsala, Sweden; Samuel Dunn at the Royal Observatory, Greenwich; Charles Green at King George's Island; Samuel Horsley at Oxford; and William Smith at Norriton. These observers are distinguished from their contemporaries by the interesting graphic aids they used to present their studies.

      '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!

    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.

  6. The economics of well-being.

    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.

    Marine ecosystems are increasingly at risk from overexploitation and fisheries collapse. As managers implement recovery plans, shifts in species interactions may occur broadly with potential consequences for ecosystem structure and function. In kelp forests off San Nicolas Island, California, USA, we describe striking changes in size structure and life history traits (e.g., size at maturation and sex change) of a heavily fished, ecologically important predator, the California sheephead (Semicossyphus pulcher). These changes occurred in two phases: (1) after intense commercial fishery exploitation in the late 1990s and (2) following recovery in the late 2000s, nearly a decade after management intervention. Using gut contents and stable-isotope values of sheephead and their prey, we found evidence for a dietary niche expansion upon recovery of population size structure to include increased consumption of sea urchins and other mobile invertebrate grazers by larger sized fish. By examining historical diet data and a time series of benthic community composition, we conclude that changes in dietary niche breadth are more likely due to the recovery of size structure from fishing than major shifts in prey availability. Size-dependent predator-prey interactions may have ecosystem consequences and management measures that preserve or restore size structure, and therefore historical trophic roles of key predators, could be vital for maintaining kelp forest ecosystem health.

    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.

    Nicolas Lopez (University of California, Riverside, USA) Chi-Yong Lin (National Dong Hwa University, Taiwan) Shan-Wen Tsai (University of California, Riverside, USA) Cold atom experiments have realized a variety of multicomponent quantum mixtures, including Bose-Fermi atomic mixtures. Mixtures of fermionic atoms and diatomic molecules, which are boson, have also been obtained by tuning of the interactions with external fields. We study many-body correlations in such a system where the molecules are weakly bound and therefore pairs of fermionic atoms easily convert into and dissociate from the bound molecule state and this exchange mediates a long-range interaction between the fermions. We consider a simple many-body Hamiltonian that includes the destruction of fermionic atom pairs to form single bosonic molecules and vice versa. We employ a functional renomalization-group approach and calculate the renormalized frequency-dependent interaction vertices and fermion self-energies. We find an instability from the disordered quantum liquid phase to a BCS phase and calculate the energy scale for the transition. The unusual frequency-dependence of this mediated interaction leads to strong renormalization of the self-energy, and also affects the couplings in the BCS channel.

    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.

    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.

    The plasma assisted calcination of composite organic/inorganic submicron fibers for the preparation of inorganic fibers in submicron scale was studied. Aluminium butoxide/polyvinylpyrrolidone fibers prepared by electrospinning were treated using low-temperature plasma generated by special type of dielectric barrier discharge, so called diffuse coplanar surface barrier discharge (DCSBD) at atmospheric pressure in ambient air, synthetic air, oxygen and nitrogen. Effect of plasma treatment on base polymer removal was investigated by using Attenuated total reflectance - Fourier transform infrared (ATR-FTIR) spectroscopy. Influence of working gas on the base polymer reduction was studied by energy-dispersive X-ray spectroscopy (EDX) and CHNS elemental analysis. Changes in fibers morphology were observed by scanning electron microscopy (SEM). High efficiency of organic template removal without any degradation of fibers was observed after plasma treatment in ambient air. Due to the low-temperature approach and short exposure time, the plasma assisted calcination is a promising alternative to the conventional thermal calcination.

  14. The Tortoise Transformation as a Prospect for Life Extension.

    PubMed

    Murphy, Timothy F

    2015-12-01

    The value of extending the human lifespan remains a key philosophical debate in bioethics. In building a case against the extension of the species-typical human life, Nicolas Agar considers the prospect of transforming human beings near the end of their lives into Galapagos tortoises, which would then live on decades longer. A central question at stake in this transformation is the persistence of human consciousness as a condition of the value of the transformation. Agar entertains the idea that consciousness could persist in some measure, but he thinks little is to be gained from the transformation because the experiences available to tortoises pale in comparison to those available to human beings. Moreover, he thinks persisting human consciousness and values would degrade over time, being remade by tortoise needs and environment. The value available in the transformation would not, then, make the additional years of life desirable. Agar's account does not, however, dispose of the tortoise transformation as a defensible preference. Some people might still want this kind of transformation for symbolic reasons, but it would probably be better that no human consciousness persist, since that consciousness would be inexpressible as such. Even so, it is not irrational to prefer various kinds of lifespan extension even if they involve significant modifications to human consciousness and values.

    Written in IDL, the DRAGraces pipeline is designed to reduce and extract data from the Gemini high-resolution spectrograph GRACES*. It is barely more than a thousand lines long, and everyone is invited to download, use and modify it as needed (https://github.com/AndreNicolasChene/DRAGRACES/releases/tag/1.0.1).This poster details how to retrieve observed GRACES data from the Gemini Observatory Archive, and explains how to run DRAGraces. It also describes the pipeline's steps, capability and performances. It is recommended to use this code and/or the other open soure pipeline, OPERA, to obtain an optimized extraction of GRACES data, before publication. It is the best way to keep control on all the reduction steps, most importantly calibration.*Gemini Remote Access to CFHT ESPaDOnS Spectrograph (GRACES) is the result of a cooperation between the Canada-France-Hawaii Telescope (CFHT), Gemini, and NRC-Herzberg (Canada). It combines the large collecting area of the Gemini North telescope with the high resolving power and high efficiency of the ESPaDOnS spectrograph at CFHT, to deliver high resolution spectroscopy across the optical region. This is achieved through a 270 m fiber optics feed from the Gemini North telescope to ESPaDOnS.

    A τ/charm Factory, an e + e- collider with very high luminosity at the 2-4.6 GeV center of mass energy, to be built on the Rome University at Tor Vergata campus, was studied by the Consortium Nicola Cabibbo Laboratory and the INFN Frascati Laboratories. This project is the natural evolution of the flagship Italian project SuperB Factory, funded by the Italian Government in 2010 with a budget that turned out to be insufficient to cover the total costs of the project. The study of rare events at the τ/charm energy was already planned as a Phase-II of SuperB [1]. This design keeps all the unique features of SuperB, including the polarization of the electron beam, with the possibility to take data in a larger energy range, with reduced accelerator dimensions and construction and operation costs. A Report on the accelerator design has been published in September 2013 [2].

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

    2015-07-01

    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.

  18. New Insights On The Seismotectonics of The French Central Massif and Western France

    NASA Astrophysics Data System (ADS)

    Mazabraud, Y.; Bethoux, N.; Guilbert, J.

    Nowadays, the increase of the number of seismological stations distributed through- out France, allows a re-evaluation of the regional sismotectonics, in particular by pre- cise localisation and computation of focal mecanisms even for small magnitude earth- quakes (Nicolas et al., 1998, Bethoux et al. 1998, Sue et al., 1999; Baroux et al., 2000; Rigo et al., 1999, Souriau et al.,1998). Thanks to the LDG code "FUSION", we have mixed the bulletin data available from several networks, for the French Central massif and Western France, from January 1962 to October 2001. Then, we have divided our study area in different zones: the western Central Massif, a volcanic province (Chaine des Puys), an eocene graben (Limagne), a sedimentary basin (Bassin de Paris), and also the Charente region and the Armorican massif. Using the VELEST code (Kissling et al., 1994), we have obtain for each of those areas, a minimum 1D model (Kissling et al., 1994) which allows to improve the location of the hypocenters. These new hypocenter distributions are correlated with geological structures, and it is possible to associate swarns of events to faults recognized on the field. Some new focal mecha- nisms are computed. Then, an inversion of focal solutions available for each zone al- lows to deduce the regional stress field. Those informations will allow a re-evaluation of the seismotectonics of the northern Central Massif and Western France. In particu- lar, we propose a qualitative analysis of the major faults activity.

    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.

    Salmonella enterica is a zoonotic pathogen that has been isolated from free-ranging marine mammals throughout the world, with animals in the Channel Islands of California (USA) showing the highest prevalence. The goal of this study was to determine prevalence, antimicrobial sensitivity and genetic similarity using pulsed-field gel electrophoresis (PFGE) of Salmonella in several non-domestic animal species on San Miguel and San Nicolas Islands. Fecal samples were collected from 90 California sea lion Zalophus californianus pups, 30 northern elephant seal Mirounga angustirostris pups and 87 western gulls Larus occidentalis in the Channel Islands and 59 adult male sea lions in Puget Sound, WA (USA). Salmonella were isolated, identified and serotyped, followed by antimicrobial susceptibility testing and PFGE. Of the California sea lion pups that were sampled on the islands, 21% (n = 19) were positive for Salmonella, whereas no adults males in Puget Sound were positive. Of the northern elephant seal pups sampled, 87% (n = 26) were harboring Salmonella. Only 9% (n = 8) of western gulls were shedding Salmonella, with one of these gulls harboring the only antimicrobial resistant isolate. The serotypes found in these animals were Enteritidis, Montevideo, Newport, Reading, and Saint Paul. The only serotype that showed variation on PFGE was Newport. The pinnipeds of the Channel Islands harbor Salmonella at a higher prevalence than pinnipeds from other geographic areas observed in previous studies. Researchers and veterinarians should exercise increased caution when working with these animals due to the zoonotic potential of Salmonella.

    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.

    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.

    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.

    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.

    THE GROSS CLINIC: is an 1875 painting by Thomas Eakins which is counted among the world's most famous doctor's portraits. This picture became more topical when it was sold to the Philadelphia Museum of Art for 68 million USD in 2006. We here present aspects of how this picture can help to document surgical practice in the USA at the time it was made. A comparison with a later doctor's portrait, THE AGNEW CLINIC: painted by Eakins in 1889, : shows that many changes occurred during a short time in the end of the 19 th century. This is especially the case within infection prevention, anaesthesia and development of the surgical profession as such. From an art historical perspective it has been common to compare the portrait with the old masters' group portraits of surgeons in surgical theatres. The most known of these is Rembrandt's DR. NICOLAES TULP'S ANATOMY LECTURE: (1632). In our opinion it is more interesting to consider THE GROSS CLINIC: in connection with concomitant photographies of medical practice. The realistic motive for the painting was assessed as inappropriate and unsuitable for a piece of art at the time. Despite of this, Eakins himself regarded the picture as one of his best, and during the 20 th century THE GROSS CLINIC: has been increasingly acknowledged. Today, the picture is the piece of art that Thomas Eakins is mainly associated with.

    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 SIREN 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.

    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.

    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. These data highlight the potential for natural recovery of abalone populations over time and that further understanding of mechanisms governing host–parasite relationships will better enable us to manage declining populations.

    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.

  10. Steps of glucocorticoid action in normal and diabetic rat placenta.

    This investigation examined the effects of Streptozotocin diabetes in pregnancy on several parameters of glucocorticoid action in the rat placenta. Pregnant diabetic rats showed reduced body weight, increased adrenal weight and serum corticosterone concentrations. Glucocorticoid receptors in placental cytosol of labyrinthine zone, measured in the absence of MoO4Na2 were similar in control and diabetic rats, but after addition of MoO4Na2 receptor number were moderately, but significantly reduced in diabetic placentas (P less than 0.01). No changes in affinity were detected in saturation analysis. Furthermore, transformation of the receptor assessed by its capacity for binding to DNA-cellulose, was enhanced in diabetic animals, suggesting increased efficiency of the receptor-bound hormone. Since the function of the glucocorticoid receptor of rat placenta may be the inhibition of local progesterone production (Heller and De Nicola, J. steroid Biochem. 19 (1983) 1339-1343), we determined progesterone synthesis in vitro and found that diabetic placentas synthesized significantly less progesterone than control tissue (P less than 0.05). Lastly, we found that the metabolism of corticosterone to 11-dehydrocorticosterone, while declining in control placentas as pregnancy advanced, it was sustained in diabetic pregnancy. It is suggested that diabetic rat placentas showed increased activity towards the glucocorticoid receptor, resulting in reduction in progesterone synthesis and sustained catabolism of corticosterone. The latter may possibly constitute a compensatory mechanism to protect the fetal compartment from high levels of maternal glucocorticoids.

    The equation of state (EOS) and pressure dependence of the transverse optical (TO) Raman-active mode of cubic boron nitride (cBN) are proposed for pressure calibration in the diamond anvil cell (DAC) at high temperatures. We determined the EOS and the pressure dependence of the TO mode of cBN in the laser heated DAC up to 70 GPa and 3300 K, and cross-checked the results with ambient pressure data, theoretical density functional calculations, and empirical relations. Moreover, the thermal EOS of Ir determined in the course of the same experiment was found to be similarly consistent. The proposed high temperature pressure scale may be further improved on the basis of simultaneous measurements of density and sound velocities at high P-T conditions, which would provide an independent pressure determination. This study is in progress and will be reported at the Meeting. We thank John K. Dewhurst, Sangeeta Sharma, Chrystele Sanloup, Eugene Gregoryanz for their contribution to this study. We acknowledge the European Synchrotron Radiation Facility for provision of synchrotron radiation facilities and we would like to thank Nicola Guignot and Mohamed Mezour for assistance with the XRD measurements.

  12. Improved Universal No-Hair Relations for Neutron Stars

    The exterior gravitational field of an astrophysical body can be characterized by its multipole moments. No-hair theorems for black holes state that the exterior gravitational field can be completely described in terms of their mass and spin angular momentum. Similar no-hair like relations have been recently found for neutron stars which are approximately independent of the internal structure of the star. Missions like NICER and LOFT will observe the pulse profiles of millisecond pulsars and thermonuclear bursters. The equation-of-state (EoS) independent relations may break degeneracies among the relevant observables in the modeling of X-ray pulse and atomic line profiles. The amount of EoS independence of these approximately universal relations depends on how one adimensionalizes the multipole moments of the star with stellar mass, spin and radius. We show that for slowly-rotating neutron stars in both non-relativistic limit and full General Relativity, the optimal normalization of the multipole moments exist that minimizes the EoS dependence in the universal relations. The relations among the moment of inertia and higher order moments can be improved from the original ones approximately by a factor of two.

  13. Forces driven by morphogenesis modulate Twist Expression to determine Anterior Mid-gut Differentiation in Drosophila embryos

    NASA Astrophysics Data System (ADS)

    Farge, Emmanuel

    2008-03-01

    By combining magnetic tweezers to in vivo laser ablation, we locally manipulate Drosophila embryonic tissues with physiologically relevant forces. We demonstrate that high level of Twist expression in the stomodeal primordium is mechanically induced in response to compression by the 60±20 nN force developed during germ-band extension (GBE). We find that this force triggers the junctional release and nuclear translocation of Armadillo involved in Twist mechanical induction in the stomodeum in a Src42A dependent way. Finally, stomodeal-specific RNAi-mediated silencing of Twist during compression impairs the differentiation of midgut cells, as revealed by strong defects in Dve expression and abnormal larval lethality. Thus, mechanical induction of Twist overexpression in stomodeal cells is necessary for subsequent midgut differentiation.

    The aim of this work is to show the correlation between the plasma propagation in the footprint of an atmospheric pressure plasma jet on a flat polymer surface and the plasma treatment impact on the polymer properties. An argon plasma jet working in open air is used as plasma source, while PET thin films are used a substrates for plasma treatment. Light emission photographs are taken with an ICCD camera to have a close look at the generated structures in the plasma jet footprint on the surface. Water contact angle (WCA) measurement and X-ray photoelectron spectroscopy (XPS) analysis are also performed to obtain information about the impact of the plasma treatment on the PET surface characteristics. A variation in ICCD camera gate duration (1 µs, 100 µs, 50 ms) results in the photographs of the different plasma structures occurring during the plasma propagation on the flat PET surface. Contact angle measurements provide results on improvement of the PET hydrophilic character, while XPS analysis shows the distribution of atomic elements on the treated substrate surface. Light emission images help explaining the obtained WCA and XPS results.

    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.

    Island foxes (Urocyon littoralis) are endemic to six of the eight California Channel Islands (USA). The island fox is classified as a threatened species by the State of California, and recently three of the six subspecies have experienced abrupt population declines. As part of a continuing effort to determine the cause of the declines, we tested island fox serum samples collected in 1988 (n = 176) and 1997-98 (n = 156) over the entire geographic range of the species for seroprevalence of canine heartworm (Dirofilaria immitis) antigen. Using a commercially available enzyme-linked immunosorbent assay (PetChek, Idexx Laboratories, Westbrook, Maine, USA) we detected heartworm antigen in four of the six populations of island foxes. On San Miguel and Santa Rosa Islands, seroprevalence in adult foxes was >85% (n = 62) in 1988 and increased to 100% (n = 24) in 1997-98. On Santa Cruz Island, seroprevalence in adult foxes decreased from 83% (n = 30) to 58% (n = 26), whereas on San Nicolas Island, seroprevalence increased from 25% (n = 32) to 77% (n = 30) during the same period. All of the pups assayed (n = 33) were seronegative. The seroprevalences of heartworm reported herein for the four populations of island foxes are the highest yet reported for a fox species. However, additional demographic data reported elsewhere suggests that heartworm has not been a major factor in the recent declines of island fox populations.

  17. Systemic Amyloid A Amyloidosis in Island Foxes (Urocyon littoralis): Severity and Risk Factors.

    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 AA (SAA) 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% [n= 78 of 80] vs 56% [n= 45], respectively;P< .0001), and medullary deposition was more commonly severe (19% [n= 20 of 105]) as compared with glomeruli (7% [n= 7];P= .01). Univariate odds ratios (ORs) of severe renal AA amyloidosis were greater for short- and long-term captive foxes as compared with free-ranging foxes (ORs = 3.2, 3.7, respectively; overall P= .05) and for females as compared with males (OR = 2.9;P= .05). Multivariable logistic regression revealed that independent risk factors for amyloid development were increasing age class (OR = 3.8;P< .0001), San Clemente Island subspecies versus San Nicolas Island subspecies (OR = 5.3;P= .0003), captivity (OR = 5.1;P= .0001), and nephritis (OR = 2.3;P= .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.

    Understanding of the dynamics of nanosecond scale pulse discharges in air at multiatmospheric pressure is essential for the development of transient plasma enhanced combustion in internal combustion engines. Here we report the result of our experimental investigation of cathode-directed streamer discharges in synthetic air at pressures ranging from 1 to 20 bar. Two pulse generators with maximum pulse amplitudes of 50 kV and 65 kV, pulse width of approximately 12 ns and 85 ns and pulse rise times of 5 ns and 50 ns are used to generate streamers. The electrodes are coaxial with various radial gaps up to 11.75 mm. The discharge chamber is evacuated and backfilled with synthetic dry air at room temperature. Optical data is obtained from PI-MAX 3 ICCD camera with 3 ns gate width. The streamer propagation velocity variation with applied voltage, different pressures and reduced electric field, E/P, will be shown. Preliminary results indicate that the (pd) similarity law is violated at high pressures in agreement with other recent experiments [1].[4pt] [1] ``Nanosecond Scale Discharge Dynamics in High Pressure Air,'' Pierre Tardiveau, Nicolas Moreau, Francois Jorand, Christian Postel, St'ephane Pasquiers, and Pierre Vervisch, IEEE Trans. on Plasma Sci., Vol. 36, No. 4, 2008.

    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.

    Nephrology in Rome began in the 1960s with the arrival of Ernico Fiaschi in the wake of Cataldo Cassano at the Institute of Medical Pathology (later on Clinica Medica II). A group of doctors interested in nephrology was set up, with among them Giulio A. Cinotti, who was to become full professor of nephrology at the University of Rome ''La Sapienza'' in 1980. By the end of the 1960s, the renal transplant activity had become an important asset at the Institute of Surgical Pathology (later on Clinica Chirurgica II) thanks to Paride Stefanini. A chair of surgical nephrology was instituted at the Urology Clinics of Ulrico Bracci; the chair was first held by Nicola Cerulli, who developed an intensive hemodialysis program. Around the same time, the Center for the Research and Treatment of Arterial Hypertension and Kidney Diseases became operational at the hospitals of Rome (under the responsibility of Vito Cagli at the Policlinico Umberto I), while a nephrology and dialysis unit, directed by Giancarlo Ruggieri, was set up at the San Giacomo Hospital. Many nephrology-related ''cultural'' activities started to be undertaken thanks to the ''Gruppo Laziale di Nefrologia Medica e Chirurgica'' founded by Drs Cagli, Cerulli, and Cinotti. Two national congresses were organized by Giulio Cinotti in 1979 (Fiuggi) and 1992 (Rome).

    This paper reports the results of an extensive study of with the in situ mass spectrometry analysis of gaseous phase species produced by an atmospheric plasma glow discharge in N2-CH4 gas mixtures (with methane concentrations ranging from 1% to 4%). The products are studied using proton-transfer-reaction mass spectrometry (PTR-MS). HCN and CH3CN are identified as the main gaseous products. Hydrazine, methanimine, methyldiazene, ethylamine, cyclohexadiene, pyrazineacetylene, ethylene, propyne and propene are identified as minor compounds. All the detected compounds and their relative abundances are determined with respect to the experimental conditions (gas composition and applied power). The same molecules were observed by the Cassini-Huygens probe in Titan's atmosphere (which has same N2-CH4 gas mixtures). Such, experiments show that the formation of such complex organics in atmospheres containing C, N and H, like that of Titan, could be a source of prebiotic molecules.

    The Syracuse area (Southeastern Sicily, Italy) is famous since ancient times for its natural springs, like Aretusa and Ciane, as well as for the hydraulic management handicraft know from 480 B.C. Unfortunately, the recent hyper-exploitation of the underground water resources and the concomitant decrease of the precipitations caused a general lowering of the piezometric level of the aquifers therefore enhancing the intrusion of marine salty waters. In the present work, numerous hydrochemical parameters have been investigated, among which the pH, the total dissolved solid, the electric conductivity, the temperature and the concentration of Ca, Mg, Na, K, HCO3, Cl and SO4. The data have been collected from five well fields located at different distances from the coast. Analyses have been performed in order to understand the relationships between the intense exploitation and the geochemical characteristics of the underground water resources. Our results obtained by applying classical geochemical methodologies integrated with techniques of multivariate statistics emphasise, firstly, the predominance of the Ca-HCO3 hydrochemical facies. Secondly, we could determine the evolution of mixing phenomena between salty and fresh waters approaching the coast line (San Nicola field). This behaviour is mainly associated to the pumping increase. Obviously, this intrusive process characterised by chlorides concentrations larger than 2000 mg/l affects all the coastal natural environment and generates severe problems to the entire aqueduct network.

    Since somatostatin (SRIF) inhibits the release of growth hormone (GH), its immunoneutralization may provide an alternative to GH therapy as a means of enhancing somatic growth in fish. The present study examined the feasibility of accelerating growth in juvenile chinook salmon by means of antiSRIF administration. Yearling salmon of Nicola River stock (BC, Canada) were injected intraperitoneally every 5 days, for a total of 40 days, with either SRIF (1 μg g-1 body wt.), antiSRIF (SOMA-10, 1 μg g(-1)), recombinant bovine GH (rbGH, 2.5 μg g(-1)), recombinant porcine GH (rpGH, 2.5 μg g(-1)) or saline (controls). No significant differences were observed in length, weight or final condition factor (k) between the SRIF-treated and control fish over the experimental period. However, the fish treated with the antiSRIF were significantly (p ≤ 0.05) longer and heavier than the control salmon after 25 and 30 days respectively. Furthermore, antiSRIF treatment caused a lowering in k when compared to the control salmon. Fish injected with rbGH or rpGH were significantly longer and heavier than all other groups (p ≤ 0.05), after only 5 days. GH treated groups also returned higher k when compared against all other treatments (p ≤ 0.05). No differences were observed in growth between the two rGH treatments over the experimental period.

    Mo2BC thin films show a favourable combination of high stiffness, hardness and elastic modulus together with moderate ductility. In this study we focused on the comparison of mechanical properties of Mo-B-C thin films with different structures (nanocrystalline or amorphous). The thin films were deposited on steel, hard metal and silicon substrates using DC magnetron sputtering. The mechanical properties of Mo-B-C films were studied using indentation techniques under both quasistatic and dynamic conditions using a wide range of loads from 50 μN up to 1 N. The results showed that even amorphous Mo-B-C thin films had high hardness of 19.5 ± 0.5 GPa and elastic modulus of 276 ± 5 GPa. Their hardness is comparable with the common amorphous diamond-like carbon coatings. Moreover, their fracture toughness is significantly higher. The results of mechanical tests were correlated with microstructure observations carried out using scanning and transmission electron microscopy. The images of the deformed area under the residual indentation imprints showed no cracking even after high loads or after indentation with sharp cube corner indenter.

    Three famous pharmacists were working in the Muséum national d'histoire naturelle in Paris, in the field of earth sciences: Louis Nicolas Vauquelin (1763-1829), André Laugier (1770-1832) and Alfred Lacroix (1863-1948). Vauquelin, professor of Chemical arts, established the chemical composition of numerous minerals, which led him to the discovery of new chemical elements. He also took a hand in demonstrating the extra-terrestrial origin of meteorites. Laugier, professor of General chemistry, was an admitted expert in the analytical field of these rocks. Lacroix, who held during more than forty years the chair of Mineralogy in the Museum, carried out major scientific work. This field working naturalist who was also famous vulcanologist placed his studies of the mineral species into a petrographical context. He described numerous new minerals, took an interest in their origin and classification of the volcanic rocks, as well as in contact metamorphism. In other respects, he increased the collections in the Museum (minerals, rocks, meteorites). The works of Vauquelin, Laugier and Lacroix contributed to advance those begun by some scientists of the Jardin du Roi, as Buffon or the Rouelle brothers before the French Revolution.

    The phase modulation of transparent gas can be detected using Fraunhofer diffraction technique, which we call optical wave microphone (OWM). The OWM is suitable for the detection of sonic wave from audible sound to ultrasonic wave. Because this technique has no influence on sound field or electric field during the measurement, we have applied it to the sound detection for the electric discharges. There is almost no research paper that uses the discharge sound to examine the electrical discharge phenomenon. Two-dimensional visualization of the sound field using the OWM is also possible when the computerized tomography (CT) is combined. In this work, coplanar dielectric barrier discharge sin different gases of Ar, N2, He were characterized via the OWM as well as applied voltage and discharge current. This is the first report to investigate the influence of the type of the atmospheric gas on the two-dimensional sound field distribution for the coplanar dielectric barrier discharge using the OWM with CT.

    This work was aimed at experimental investigations of deactivation of different types of microorganisms by using atmospheric pressure low-temperature microwave microplasma source (MmPS). The MmPS was operated at standard microwave frequency of 2.45 GHz. Its main advantages are simple and cheap construction, portability and possibility of penetrating into small cavities. The microplasma deactivation concerned two types of bacteria (Escherichia coli, Bacillus subtilis) and one fungus (Aspergillus niger). The quality as well as quantity tests were performed. The influence of the microorganism type, oxygen concentration, absorbed microwave power, microplasma treatment time and MmPS distance from the treated sample on the microorganism deactivation efficiency was investigated. All experiments were performed for Ar microplasma and Ar/O2 microplasma with up to 3% of O2. Absorbed microwave power was up to 50 W. The Ar flow rate was up to 10 L/min. The sample treatment time was up to 10 s.

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 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.

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

    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.

    We succeeded in generating an atmospheric pressure Townsend discharge (APTD) in air by using a simple DBD device that consists of alumina barriers and plane electrodes. So far, we applied the APTD to an ozonizer and found that the ozone generation efficiency was higher by the APTD mode than by the conventional DBD mode in larger specific input energy region. It is well known that an operation under an optimized high gas pressure is advantageous for efficient ozone generation from air. In this paper, we investigated whether the Townsend discharge (TD) in dry air in high pressure up to 0.17 MPa can be generated or not. From the observation results of current waveforms and discharge photographs, we found that (1) the discharge currents flow continuously and have only one peak in every half cycle in all gas pressure and (2) filamentary discharges are not recognized between barriers in all gas pressure. These features completely agree with the features of the APTD we reported. Therefore, we concluded that our TD can be generated even in dry air in the pressure range of 0.1 and 0.17 MPa.

    Among the ambassadors of Romanian science and culture, we include the doctor Vintilă Ciocâlteu. Along with Victor Babeş, Nicolae Paulescu and George Emil Palade, Vintilă Ciocâlteu contributed further, by the reagent which he prepared together with Otto Folin, to the completion and deepening of the knowledge of cell biology within the medical agricultural, horticultural research or industrial chemistry. A multi-faceted personality, V. Ciocâlteu was also a remarkable poet, who entered into an unjust and hopeless conflict with the communist regime. Just like many of his compatriots, he was deleted from medical or literature books, was expelled from the department of Medicine in Bucharest and was charged with offences that he did not commit. But his name could not be deleted from the laboratory methods which used - the Reagent Folin-Ciocâlteu! Today, doctor Vintilă Ciocâlteu continues to promote the fame of the Romanian medicine in the world. PMID:26527940

    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."

    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.

    During its long history, the Clinica del Lavoro Luigi Devoto has produced numerous internationally recognized scientific contributions in the specific field of occupational medicine and health, and in other broader areas as, for example, immunology, toxicology, cytogenetics. Pivotal in this activity was the figure of Enrico C. Vigliani, director of the Clinica for over 35 years. We mention here, in particular, the results of the study of "early" markers of lead intoxication; the research on the carcinogenicity of benzene and aromatic amines; the study of the pathogenesis of silicosis and byssinosis; the study of cytogenetic damage after exposure to industrial toxic chemicals; the technical research for dust abatement in mines. Such research also played a major role in the development of pulmonary medicine, toxicology and immunology in Italy, and conferred scientific dignity on the newborn "industrial hygiene" discipline thanks to the work of Nicola Zurlo. Today, the Clinica's research is maintained at international standards especially by the work of thematic Research Centers recently established within the Clinica, covering fields such as occupational and environmental toxicology, occupational oncology, ergonomics, respiratory disease and allergy, psycho-social risk factors. These Centers are also devoted to the development of innovative methods in epidemiology, toxicology, psychology, molecular biology, and ergonomic measurement for the identification and evaluation of health risks at work.

    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.

    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.

  19. 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.

    Fahr syndrome (FS) refers to basal ganglia calcification that is associated with many neurological and psychiatric abnormalities and appears as secondary to other diseases. We described a case of FS patient who was admitted in the Department of Neurology of "Prof. Dr. Nicolae Oblu" Clinical Emergency Hospital, Iassy, Romania, with seizure and mood disorders. On CT, the cause of seizure was found to be the bilateral calcifications of cerebellum, basal ganglia, thalamus and internal capsule. As the patient died after 15 days of hospitalization due to new seizures and gastrointestinal infection, an autopsy was made. Grossly, there were bilateral symmetrically gritty yellow areas in basal ganglia, thalami, internal capsule, cerebral cortex, cerebellar folia, dentate nucleus, and brain stem. A detailed histopathological examination revealed five types of calcium deposits within the walls of capillaries, small and medium-sized arteries from the intracerebral affected areas, chronic lymphocytic thyroiditis and fibro-adipose tissue instead of parathyroids. We consider that intracerebral symmetrical calcifications were the results of the hypoparathyroidism determined by an ancient autoimmune parathyroiditis that evolved to fibrosis as at microscopy we found an autoimmune thyroiditis.

    Adkins, G Matthew

    2008-12-01

    This essay argues for the emergence of a cultural and epistemological divide between amateur savants and members of the Royal Academy of the Sciences in late Old Regime and revolutionary France and suggests that the amateur ideal rose in significance even as intellectual activity came to be increasingly centralized in the postrevolutionary era. At the crux of the tensions between the amateur ideal and the professionalizing reality in the immediate postrevolutionary period stood Aubin-Louis Millin and his journal, the Magasin Encyclopédique. The essay examines, in particular, the revival in the pages of the Magasin Encyclopédique of interest in Nicolas-Claude Fabri de Peiresc, the seventeenth-century icon of an amateur ideal in which investigations in the natural sciences and scholarship were private, decentralized, often provincial activities. Although the sciences in the revolutionary and Napoleonic eras were often perceived as forward looking and dismissive of the past, this essay finds that a sentimental and nostalgic attachment to the past-to a myth of Peiresc-continued to play an important role in the identity of postrevolutionary men of letters.

    Historians usually consult letters by artists in order to verify and to interpret works of art. These letters contain basic information about technical, social and psychological aspects. As personal documents, they have always enjoyed a particular esteem among biographers and collectors. On the other hand, historians have often suggested that artists are the melancholic outcasts of society. But even a brief glance at the available correspondence proves that the majority of letters do not support this diagnosis. When artists mention their own physical constitution, they apologise for delays or request further financial support. Moreover, the letter is subject to literary codes according to which medical issues are adopted as a metaphor for more general problems. The French classical painter Nicolas Poussin, on whom the present analysis is based, displayed a particular interest in questions of style and literacy. His writings should then be regarded as complex "compositions" that stand comparison with his artistic oeuvre rather than mere informal messages to his readers. Indeed, correspondences between artists and their patrons, colleagues and friends form a "genre" in their own right that can be drawn upon as a reliable source for research in medical history.

    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.

Such multi-instrument calibration would enable a better comparison of instrument performances during the mission, as well as aid in the interpretation of the in-situ measurements. At the CNRS in Orléans, the Observatoire des Sciences de l'Univers de la region Centre is creating a collection of well-characterised rocks that will be available for testing and calibrating instruments to be flown on space missions. The characteristics of the collection's analogue materials will be described in an online database. In view of the upcoming 2018 ExoMars rover mission, we are concentrating initially on materials of direct relevance to Mars. The initial collection includes basalts (ultramafic, weathered, andesitic, hydrothermally-silicified); sediments (volcanic, biolaminated, banded iron formation); and minerals (silica, evaporites, clays, Fe oxides). This set of samples will be augmented with time. All samples will be characterised petrographically, petrologically, and geochemically using the types of analyses likely to be performed during an in-situ mission: hand specimen description, optical microscopy, mineralogical analysis (XRD, Raman and IR spectrometry), elemental analysis (EDX, microprobe, ICP) and organics analysis (Raman, pyr-GCMS).

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

    Resource preservation is one of the main challenges in Europe, together with waste management and recycling; recently several researchers are interested in the recovering of critical raw materials and secondary raw materials from landfill. Aggregate supply, even if it is not "critical" sensus stricto (s.s.), is one of the European priorities (low value but high volume needs). On the other side, the management of quarry waste , mainly from dimension stones, but also as fines from aggregate crushing, is still a matter of concern. Such materials are managed in different ways both locally and nationwide, and often they are landfilled, because of an unclear legislation and a general lack of data. Most of time the local authorities adopt the maximum precaution principle or the enterprises find it little profitable to recover them, so that the sustainable recycling of such material is not valued. Several studies have shown, depending on the material specific characteristics, the viability of recycling quarry waste into new raw materials used in glass and ceramic industries, precast concrete production, infrastructures etc. (Loudes et al. 2012, Dino&Marian 2015, Bozzola et al 2012, Dino et al. 2012, etc.). Thus, aggregate production may be one of the profitable ways to use quarry waste and is falling under the priority of EU (aggregate supply). Positive economic and environmental effects are likely to be achieved by systematic recycling of quarry waste planned by industries (industrial planning) and public authorities (national and local planning of aggregate exploitation). Today, the recycling level varies to a great extent and systematic recovery is not common among European Countries. In Italy and Norway no significant incentives on recycling or systematic approaches for local aggregate exploitation exist. The environmental consequences can be overexploitation of the natural resources, land take for the landfills, environmental contamination and landscape alteration by

    The TV broadcast discusses problems of the modernization of the Romanian astronomical infrastructure, the worst in Eastern Europe. It presents the TELEROM project which proposed to establish a new EU-funded robotic 1,3 m telescope, a project finally rejected by the Astronomical Institute of the Romanian Academy mainly due to the incompetence of the director of this Institute, Dr. Vasile Mioc. It is mentioned that this was the second very promising project failed under the same director, after the project ASTEROS in value of 15 million Euro to establish two modern telescopes was also lost in the recent years. The total cost of the TELEROM project was 1,5 million Euro, according to the agreement with the EU foundation for Regional Development (director Hanns Ruder Institut für Theoretische Astrophysik, Universität Tübingen, Germany - the TELEROM auto-dimissed project director). The facilities from this implementation were very promising in observations of Solar system objects (asteroids, near Earth asteroids, comets), few hundred millions of faint stars, quasars, exoplanets and galaxies. Initially, the director Vasile Mioc and the governing body of the Romanian Astronomical Institute intended to place the telescope in Romania in very bad astroclimatic conditions, namely in the old Feleac observatory, very close to the very highly polluted and quite clouded city of Cluj-Napoca. Many opposite considerations (Dr. Marian Doru Suran from Bucharest, many Romanian astronomers from the Diaspora and a group of 68 astronomers, professors, public outreach people and students from Romania and Diaspora supporting TELEROM) were totally disregarded! Due to refuse to place the telescope in very good astroclimatic conditions (in Canary Islands or Chile) and also due to the impossibility to establish a decent national astronomical observatory in Romania by the direction of the Institute in agreement with the State body of Romania ("Academia Romana" and "Autoritatea Nationala pentru

    The Western Antarctic Peninsula experiences a temperature increase that is higher than in other parts of Antarctica. Within the last 50 years the tidewater glaciers in the tributary fjords of Maxwell Bay (King George Island) have retreated landwards with increasing speed. Meltwaters mobilize fine-grained sediments and transport those in plumes out of the coves into Maxwell Bay. Our hypothesis is that meltwater sediments characterize warmer climate periods of the Holocene. Marine sediment cores recovered along a profile of the eastern slope of Maxwell Bay were studied. The cores were taken in high-accumulation areas at the entrances of Collins Harbor, Marian and Potter coves. We measured the grain-size distribution in 1-cm steps in each core with a Laser diffraction particle analyzer (range 0.04-2500 µm) in order to resolve shifts in grain size compositions in very high resolution. We undertook different approaches for reliable age determination of the sediments. Since marine biogenic carbonate suitable for radiocarbon age determination is sparse, radiocarbon dating of the extracted humic acid fraction of the bulk sediment was included. Unfortunately, these age determinations turned out to be not reliable, likely because they are overprinted by an unknown older radiocarbon source. Preliminary results suggest that the cores cover approximately the last 2000 years. The magnetic susceptibility (MS) parameter fluctuates throughout the cores. It is negatively correlated to the amount of total organic carbon (TOC) and biogenic opal, suggesting dilution of the MS signal through higher input of organic material. Together with the bathymetry data, sub-bottom profiles reveal information on the interior of the topography and the geometry of the deposited sediments. The profiles obtained in Potter Cove show almost no sediment penetration suggesting either a very thin sediment cover and/or highly reworked unsorted sediments. The sub-bottom profiles from Maxwell Bay penetrate

    order to insure Braeside would continue to operate long after he could not be present, Bob and his wife, Marian, donated his observatory and adjacent home to the Arizona Sate University astronomy department for student use. In the last years of his life, he made sure everything worked for the students who used it in the early evening hours and then he continued on with his own research programs in the later half of the night and on weekends. His interest in students was not limited to those using his own telescope, although many visited and used his observatory from as far away as New York. Bob made an effort to work with students in other schools. He helped Flagstaff High School to build their own observatory on their grounds and worked with students from other states. Besides his night observing programs, Bob continued with his love and expertise in flying during the day. He donated his plane and time for volunteer mercy missions with Angel Flight and Flights for Life, flying patients to hospitals and medical supplies where they were needed. It was on one of these missions that Birdie went down about 40 miles north of Phoenix on November 13, 2003. The cause of the plane crash was not clear but the outcome was certain: the world had lost an admired, professional amateur astronomer and humanitarian. He is survived by his wife, Marian, his sister Louise, and his three daughters, Leslie, Sara and Amy, as well as stepchildren, grandchildren and many students he mentored. The stories told, and the pictures shown, at his Memorial at Lowell Observatory summarized a free-spirited and dedicated individual who lived life fully, joyfully and generously. His sense of humor, and spirited camaraderie will be missed as much as his observations.

  12. 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.

Statistical analysis across all screened lines shows that genotype is a strong predictor of recovery sleep, independent from effects of genotype on baseline sleep. Conclusions: Our data show that rebound sleep following thermogenetic sleep deprivation can be genetically separated from sleep at baseline. This suggests that genetically controlled mechanisms of sleep regulation not manifest under undisturbed conditions contribute to sleep rebound following thermogenetic sleep deprivation.

    Eradication of opium smoking during the Japanese colonial period is one of the most proud medical accomplishments in Taiwan. The mission was accomplished mainly due to a governmental policy of gradual prohibition in 1897 and the establishment of the Government Center Hospital for Opium Addicts in 1930. Professor Tsungming Tu, medical director of the Government Center Hospital, was responsible for the unique medical treatment of opium addiction there. The latter consisted of an immediate withdrawal of opium smoking which was partly substituted by small amounts of morphine in gradual reduction, and at the same time special pills were given to enhance the sympathetic activity also to lessen the withdrawal symptoms. By such treatment, the habit of opium smoking could often be eliminated in a few weeks. The success rate was 46%. Shortly after the World War II, the number of opium smokers in Taiwan became negligible. In early colonial period, however, there were grass roots movements as well as private efforts by physicians of Western medicine to treat opium addiction. In 1898, the Flying Phoenix Society which was a laymen organization worshipping deities began to use supernatural power to force the addicts to stop opium smoking. More than thirty thousand were enlisted and the success rate was 58%. In 1908, the enthabitual treatment in a private correction infirmary called 'Newmatou' consisted of a substitute treatment using morphine to replace opium and a gradual reduction in morphine dosage afterwards. All addicts were hospitalized until treatment goal was achieved. Among 55 addicts thus treated, 53 (96%) were ridded of opium smoking habit. The treatment method was almost identical to that employed by Professor Tu. Another physician, Dr. Ching-yue Lin, who worked at the Red Cross Hospital in Taipei, also used substitute treatment, replacing opium by heroine, and obtained a success rate of 80%. Dr. Lin published his comprehensive study on opium addiction and treatment

  15. Quantifying wave-breaking dissipation using nonlinear phase-resolved wave-field simulations

    We propose to understand and quantify wave-breaking dissipation in the evolution of general irregular short-crested wave-fields using direct nonlinear phase-resolved simulations based on a High-Order Spectral (HOS) method (Dommermuth & Yue 1987). We implement a robust phenomenological-based energy dissipation model in HOS to capture the effect of wave-breaking dissipation on the overall wave-field evolution (Xiao et al 2013). The efficacy of this model is confirmed by direct comparisons against measurements for the energy loss in 2D and 3D breaking events. By comparing simulated wave-fields with and without the dissipation model in HOS, we obtain the dissipation field δ(x,y,t), which provides the times, locations and intensity of wave breaking events (δ>δc). This is validated by comparison of HOS simulations with Airborne Terrain Mapper (ATM) measurements in the recent ONR Hi-Res field experiment. Figure (a) shows one frame of simulated wave-field (with dissipation model). Figure (b) is the corresponding measurement from ATM, where a large wave breaking event was captured. Figure (c) is the 3D view of the simulated wave-field with the colored region representing dissipation with δ>δc. The HOS predicted high-dissipation area is found to agree well with the measured breaking area. Based on HOS predicted high-dissipation area (δ>δc), we calculate Λ(c) (Phillips 1985), the distribution of total length of breaking wave front per unit surface area per unit increment of breaking velocity c. Figure (d) shows the distribution Λ(c) calculated from HOS. For breaking speeds c greater than 5m/s, the simulated Λ(c) is in qualitative agreement with Phillips theoretical power-law of Λ(c)~c-6. From δ(x,y,t), we further quantify wave breaking by calculating the whitecap coverage rate Wr(t) and energy dissipation rate ΔE'(t), and study the evolution of Wr and ΔE' to understand the role of wave breaking in nonlinear wave-field evolution. We obtain HOS simulations

    2014-01-01

    Background Coral reefs worldwide are being harmed through anthropogenic activities. Some coral reefs in Thailand remain well-preserved, including the shallow coral reefs along Kra island, Nakhon Si Thammarat province. Interestingly, the microbial community in this environment remains unknown. The present study identified biodiversity of prokaryotes and eukaryotes of 0.22-30 μm in sizes and their metabolic potentials in this coral reef surface in summer and winter seasons, using 16S and 18S rRNA genes pyrosequencing. Results The marine microbial profiles in summer and winter seasons comprised mainly of bacteria, in phylum, particular the Proteobacteria. Yet, different bacterial and eukaryotic structures existed between summer and winter seasons, supported by low Lennon and Yue & Clayton theta similarity indices (8.48-10.43% for 16S rRNA, 0.32-7.81% for 18S rRNA ). The topmost prokaryotic phylum for the summer was Proteobacteria (99.68%), while for the winter Proteobacteria (62.49%) and Bacteroidetes (35.88%) were the most prevalent. Uncultured bacteria in phyla Cyanobacteria, Planctomycetes, SAR406 and SBR1093 were absent in the summer. For eukaryotic profiles, species belonging to animals predominated in the summer, correlating with high animal activities in the summer, whereas dormancy and sporulation predominated in the winter. For the winter, eukaryotic plant species predominated and several diverse species were detected. Moreover, comparison of our prokaryotic databases in summer and winter of Kra reef surface against worldwide marine culture-independent prokaryotic databases indicated our databases to most resemblance those of coastal Sichang island, Chonburi province, Thailand, and the 3 tropical GOS sites close to Galapagos island (GS039, GS040 and GS045), in orderly. Conclusions The study investigated and obtained culture-independent databases for marine prokaryotes and eukaryotes in summer and winter seasons of Kra reef surface. The data helped

    PubMed Central

    2012-01-01

    Background Tha Wang and Tham Phang coasts, though situated at similar oceanographic positions on Sichang island, Chonburi province, Thailand, are different in bay geography and amount of municipal disturbances. These affect the marine ecosystems. The study used metagenomics combined with 16S and 18S rDNA pyrosequencing to identify types and distributions of archaea, bacteria, fungi and small eukaryotes of sizes ranges 0.45 and ~30 μm. Results Following the open bay geography and minimal municipal sewages, Tham Phang coast showed the cleaner water properties, described by color, salinity, pH, conductivity and percent dissolved oxygen. The 16S and 18S rDNA metagenomic profiles for Tha Wang and Tham Phang coasts revealed many differences, highlighting by low Lennon and Yue & Clayton theta similarity indices (66.03-73.03% for 16S rDNA profiles, 2.85-25.38% for 18S rDNA profiles). For 16S rDNA, the percent compositions of species belonging to Proteobacteria, Bacteroidetes, Cyanobacteria, Firmicutes, Verrucomicrobia, Gammatimonadetes, Tenericutes, Acidobacteria, Spirochaetes, Chlamydiae, Euryarchaeota, Nitrospirae, Planctomycetes, Thermotogae and Aquificae were higher or distinctly present in Tha Wang. In Tham Phang, except Actinobacteria, the fewer number of prokaryotic species existed. For 18S rDNA, fungi represented 74.745% of the species in Tha Wang, whereas only 6.728% in Tham Phang. Basidiomycota (71.157%) and Ascomycota (3.060%) were the major phyla in Tha Wang. Indeed, Tha Wang-to-Tham Phang percent composition ratios for fungi Basidiomycota and Chytridiomycota were 1264.701 and 25.422, respectively. In Tham Phang, Brachiopoda (lamp shells) and Mollusca (snails) accounted for 80.380% of the 18S rDNA species detected, and their proportions were approximately tenfold greater than those in Tha Wang. Overall, coastal Tham Phang comprised abundant animal species. Conclusions Tha Wang contained numerous archaea, bacteria and fungi, many of which could synthesize

    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. Pollitz et.al, (2012), explained that the two violent earthquakes would be evidence of a break in the Indo-Australian Plate Tectonics caused earthquakes around

    2014-01-01

    Background The nasal microbiota of pigs has been poorly assessed but could play a role in carriage of important microorganisms such as methicillin-resistant Staphylococcus aureus (MRSA). The objectives of this study were to describe the nasal microbiota in slaughter age pigs, to evaluate the impact of farm management on the nasal microbiota and to provide a preliminary assessment of the influence of the microbiota on MRSA carriage. Results Nasal swabs were collected from five MRSA positive and eight MRSA negative pigs on one farm that used a liquid feeding system and routine tylosin treatment, and seven MRSA negative pigs from an antibiotic-free farm that used conventional feeding. A total of 946310 sequences passed all quality control filters. The number of sequences per sample ranged from 4307 to 165656 (mean 56092, SD 40007). CatchAll analysis of richness predicted a mean of 1749 OTUs (range 213–3736, SD 996). Overall, 6291 OTUs were identified, yet 5125 (81%) were identified less than 10 times and the 12 most abundant OTUs accounted for 80.7% of sequences. Proteobacteria predominated in all but two samples. Liquid-fed/tylosin-exposed pigs had significantly lower relative abundances of Verrucomicrobia (P = 0.004), Fibrobacteres (P = <0.0001) and sequences unclassified at the phylum level (P = 0.028). When comparing only liquid-fed pigs, MRSA carriers had significantly more Bacteroidetes (P = 0.037) than MRSA negative pigs. 124 genera were identified, with Moraxella accounting for 35.4% of sequences. In the Jaccard index tree, five of eight MRSA positive pigs clustered closely together, as did six of the seven conventionally-fed pigs. A significant difference was identified between conventional and liquid-fed pigs using parsimony test with the Jaccard (P < 0.001) but not the Yue&Clayton (P = 0.26) index. There were no significant differences between MRSA positive and negative pigs (P = 0.133 and 0.175). OTUs belonging to Firmicutes

    2005-01-01

    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

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

    2010-05-01

    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

    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.

    Recent studies have identified signs of an unseen, distant ninth planet in our solar system. How might we find the elusive Planet Nine? A team of scientists suggests the key might be cosmology experiments.AHypothetical PlanetOrbits of six distant Kuiper-belt objects. Their clustered perihelia and orbital orientations suggest they may have been shepherded by a massive object, hypothesized to be Planet Nine. [Caltech/Robert Hurt]Early this year, a study was published that demonstrated that the clustered orbits of distant Kuiper belt objects (and several other features of our solar system) can be explained by the gravitational tug of a yet-undiscovered planet. This hypothetical Planet Nine is predicted to be a giant planet similar to Neptune or Uranus, with a mass of more than ~10 Earthmasses, currently orbiting ~700 AU away.In a recent study, a team of scientists led by Nicolas Cowan (McGill University in Canada) has estimated the blackbody emission expected from Planet Nine. The team proposes how we might be able to search for this distant body using its heat signature.Heat from an Icy WorldCowan and collaborators first estimate Planet Nines effective temperature, based on the solar flux received at ~700 AU and assuming its internal heating is similar to Uranus or Neptune.

    1992-10-01

    Seventy-four new S isotope analyses of ore minerals and country rocks are given for the Hg deposit of Almadén. The spread of the cinnabar δ34S is narrow within each of the three orebodies, but the δ34S average values differ sufficiently between them (mean δ34S: San Nicolas = 0.2 ± 1.1 %., San Francisco = 8.1 ± 0.7%., San Pedro = 5.9 ± 1.0%.) to indicate three different mineralization episodes and possibly processes. The unweighted mean for all cinnabar samples is 5.6%. and the S source is considered to be the host-rocks, either the Footwall Shales ( δ34S = 5.5%.) or the spilites ( δ34 S = 5.1 ± 1.3%.). For geometric and chronologic reasons, the former seem the best potential source. However, the high δ34 S values of the San Francisco cinnabar cannot be explained without addition of heavy S from reduction of seawater sulphate. Orderly distributions of the δ34S values are observed in all three orebodies: (1) their increase from the stratigraphic bottom to the top in the San Pedro orebody is explained by a Rayleigh process, and (2) the maxima in the centres of the San Francisco and San Nicolas orebodies are explained by mixing of the S transporting hydrothermal fluids with seawater within the sediments. Associated pyrite and cinnabar were deposited under isotopic disequilibrium, probably because the low solubility of cinnabar caused rapid precipitation of cinnabar. The different morphological pyrite types have their own isotopic δ34S signatures. The spilites are notably enriched in S ( n = 3; average S content = 0.56%) compared to normal basalts (1000 ppm) and have an average δ34S = 5.1 ± 1.3%.. The linear relationship between the δ34S and the S content of the spilites is interpreted as a mixing line between mantle S and a constant S source, probably an infinite open reservoir. An incomplete basalt-seawater reaction at nearly constant temperature is the best explanation for this relation. The S (predominantly pyrite) of the black shales ( n = 3; δ34S

    Mathematical models and mathematical modeling play different roles in the different areas and problems in which they are used. The function and status of mathematical modeling and models in the different areas depend on the scientific practice as well as the underlying philosophical and theoretical position held by the modeler(s) and the practitioners in the extra-mathematical domain. For students to experience the significance of different scientific practices and cultures for the function and status of mathematical modeling in other sciences, students need to be placed in didactical situations where such differences are exposed and made into explicit objects of their reflections. It can be difficult to create such situations in the teaching of contemporary science in which modeling is part of the culture. In this paper we show how history can serve as a means for students to be engaged in situations in which they can experience and be challenged to reflect upon and criticize, the use of modeling and the significance of the context for the function and status of modeling and models in scientific practices. We present Nicolas Rashevsky's model of cell division from the 1930s together with a discussion of disagreement between him and some biologists as one such episode from the past. We illustrate how a group of science students at Roskilde University, through their work with this historical case, experienced that different scientific cultures have different opinions of the value of a model as an instrument for gaining scientific knowledge; that the explanatory power of a model is linked not only to the context of its use, but also to the underlying philosophical and theoretical position held by the modeler(s) and the scientists discussing the model and its use. The episode's potential to challenge students to reflect upon and criticize the modeling process and the function of models in an extra mathematical domain is discussed with respect to the notions of

  7. To speak in tongues: language, diversity and psychoanalysis.

    2002-07-01

    After reviewing the different psychoanalytical approaches to language of authors such as Freud, Lacan, Kristeva, Jung and Nicolas Abraham, the author examines the problem of 'analytical listening', of the attitude that every analyst must assume towards the words of the analysand, words that must be heard not just in terms of their content but above all in terms of their sound. We live in a culture in which visual images predominate over acoustic images and all too often this cultural trend is repeated in analysis, but it is only when we can hear the 'poetry' of the analysand's discourse that we are able to provide an 'echo', an analytical response that can co-symbolize with, that can offer to the analysand a word or a metaphor that will unlock the symbol hidden behind his or her words. The author then turns to the problem of bilinguism and its role in analysis. In her view, bilingual analysts are facilitated in their task of listening and of translation, because bilinguism facilitates the rapidity and fluidity of the analyst's associations, and at the same time sharpens his or her awareness of how the sound of a word can subtly change its meaning. The paper ends with a clinical vignette which illustrates the role that language can play in hysteria. In hysteria the dissociation between body and psyche is accompanied by a dissociation inside language itself, between verbalization and vocalization. These dissociations can be linked to the traumatic impact of the encounter between the 'language of tenderness' and the 'language of passion', between the child's attachment needs and parental sexuality. In such cases the failure of communication can be resolved principally through the use the analyst makes of the countertransference.

  8. Estimated accuracy of ground-based liquid water measurements during FIRE

    Since on goal of the First ISCCP Regional Experiment (FIRE) project is to improve our understanding of the relationships between cloud microphysics and cloud reflectivity, it is important that the accuracy of remote liquid measurements by microwave radiometry be thoroughly understood. The question is particularly relevant since the uncertainty in the absolute value of the radiometric liquid measurement is greatest at low liquid water contents (less than 0.1 mm). However it should be stressed that although uncertainty exists in the absolute value of liquid, it is well known that the observed radiometric signal is proportional to the amount of liquid in the antenna beam. As a result, changes in amounts of liquid are known to greater accuracy than the absolute value, which may contain a bias. Here, an assessment of the liquid measurement accuracy attained at San Nicolas Island (SNI) is presented. The vapor and liquid water data shown were computed from the radiometric brightness temperatures using statistical retrieval algorithms. The retrieval coefficients were derived from the 69 soundings made by Colorado State University during the SNI observations. Sources of error in the vapor and liquid measurements include cross-talk in the retrieval algorithms (not a factor at low liquid contents), uncertainties in the brightness temperature measurement, and uncertainties in the vapor and liquid attenuation coefficients. The relative importance of these errors is discussed. For the retrieval of path-integrated liquid water, the greatest uncertainty is caused by the temperature dependence of the absorption at microwave frequencies. As a result, the accuracy of statistical retrieval of liquid depends to large measure upon how representative the a priori radiosonde data are of the conditions prevailing during the measurements. The microwave radiometer measurements at SNI were supplemented by an infrared (IR) radiometer modified for measurement of cloud-base temperature. Thus

    In the future a transfer from the fossil fuel-based economy to hydrogen-based economy is expected. Therefore the development of systems for efficient H2 production becomes important. The several conventional methods of mass-scale (or central) H2 production (methane, natural gas and higher hydrocarbons reforming, coal gasification reforming) are well developed and their costs of H2 production are acceptable. However, due to the H2 transport and storage problems the small-scale (distributed) technologies for H2 production are demanded. However, these new technologies have to meet the requirement of producing H2 at a production cost of (1-2)/kg(H2) (or 60 g(H2)/kWh) by 2020 (the U.S. Department of Energy's target). Recently several plasma methods have been proposed for the small-scale H2 production. The most promising plasmas for this purpose seems to be those generated by gliding, plasmatron and nozzle arcs, and microwave discharges. In this paper plasma methods proposed for H2 production are briefly described and critically evaluated from the view point of H2 production efficiency. The paper is aiming at answering a question if any plasma method for the small-scale H2 production approaches such challenges as the production energy yield of 60 g(H2)/kWh, high production rate, high reliability and low investment cost.

    Potatoes are usually a high-glycaemic index (GI) food. Finding a low-GI potato and developing a screening method for finding low-GI cultivars are both health and agricultural priorities. The aims of the present study were to screen the commonly used and newly introduced cultivars of potatoes, in a bid to discover a low-GI potato, and to describe the relationship between in vitro starch digestibility of cooked potatoes and their in vivo glycaemic response. According to International Standard Organisation (ISO) guidelines, seven different potato cultivars were tested for their GI. In vitro enzymatic starch hydrolysis and chemical analyses, including amylose content analysis, were carried out for each potato cultivar, and correlations with the respective GI values were sought. The potato cultivars had a wide range of GI values (53-103). The Carisma cultivar was classified as low GI and the Nicola cultivar (GI = 69) as medium GI and the other five cultivars were classified as high GI according to ISO guidelines. The GI values were strongly and positively correlated with the percentage of in vitro enzymatic hydrolysis of starch in the cooked potatoes, particularly with the hydrolysis percentage at 120 min (r 0·91 and P <0·01). Amylose, dietary fibre and total starch content was not correlated with either in vitro starch digestibility or GI. The findings suggest that low-GI potato cultivars can be identified by screening using a high-throughput in vitro digestion procedure, while chemical composition, including amylose and fibre content, is not indicative.

    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.

  13. The small-voxel tracking algorithm for simulating chemical reactions among diffusing molecules

    2014-12-01

    Simulating the evolution of a chemically reacting system using the bimolecular propensity function, as is done by the stochastic simulation algorithm and its reaction-diffusion extension, entails making statistically inspired guesses as to where the reactant molecules are at any given time. Those guesses will be physically justified if the system is dilute and well-mixed in the reactant molecules. Otherwise, an accurate simulation will require the extra effort and expense of keeping track of the positions of the reactant molecules as the system evolves. One molecule-tracking algorithm that pays careful attention to the physics of molecular diffusion is the enhanced Green's function reaction dynamics (eGFRD) of Takahashi, Tănase-Nicola, and ten Wolde [Proc. Natl. Acad. Sci. U.S.A. 107, 2473 (2010)]. We introduce here a molecule-tracking algorithm that has the same theoretical underpinnings and strategic aims as eGFRD, but a different implementation procedure. Called the small-voxel tracking algorithm (SVTA), it combines the well known voxel-hopping method for simulating molecular diffusion with a novel procedure for rectifying the unphysical predictions of the diffusion equation on the small spatiotemporal scale of molecular collisions. Indications are that the SVTA might be more computationally efficient than eGFRD for the problematic class of non-dilute systems. A widely applicable, user-friendly software implementation of the SVTA has yet to be developed, but we exhibit some simple examples which show that the algorithm is computationally feasible and gives plausible results.

    This report provides a succinct summary of the physics programme of SuperB, and describes that potential in the context of experiments making measurements in flavour physics over the next 10 to 20 years. Detailed comparisons are made with Belle II and LHCb, the other B physics experiments that will run in this decade. SuperB will play a crucial role in defining the landscape of flavour physics over the next 20 years. SuperB is an approved high luminosity e{sup +}e{sup -} collider intended to search for indirect and some direct signs of new physics (NP) at low energy, while at the same time, enabling precision tests of the Standard Model (SM). This experiment will be built at a new laboratory on the Tor Vergata campus near Rome, Italy named after Nicola Cabibbo. The project has been described in a Conceptual Design Report, and more recently by a set of three white papers on the accelerator, detector, and physics programme. The main focus of the physics programme rests in the study of so-called Golden Modes, these are decay channels that provide access to measurements of theoretically clean observables that can provide both stringent constraints on models of NP, and precision tests of the SM. A number of ancillary measurements that remain important include those with observables that may not be theoretically clean, and those that can be used to provide stringent constraints on the SM but are not sensitive to NP. The remainder of this section introduces SuperB before discussing the golden modes for SuperB, precision CKM measurement modes, and an outline of the rest of this report.

    The family Oscarellidae is one of the two families in the class Homoscleromorpha (phylum Porifera) and is characterized by the absence of a skeleton and the presence of a specific mitochondrial gene, tatC. This family currently encompasses sponges in two genera: Oscarella with 17 described species and Pseudocorticium with one described species. Although sponges in this group are relatively well-studied, phylogenetic relationships among members of Oscarellidae and the validity of genus Pseudocorticium remain open questions. Here we present a phylogenetic analysis of Oscarellidae using four markers (18S rDNA, 28S rDNA, atp6, tatC), and argue that it should become a mono-generic family, with Pseudocorticium being synonymized with Oscarella, and with the transfer of Pseudocorticium jarrei to Oscarella jarrei. We show that the genus Oscarella can be subdivided into four clades, each of which is supported by either a small number of morphological characters or by molecular synapomorphies. In addition, we describe two new species of Oscarella from Norwegian fjords: O. bergenensis sp. nov. and O. nicolae sp. nov., and we compare their morphology, anatomy, and cytology with other species in this genus. Internal anatomical characters are similar in both species, but details of external morphology and particularly of cytological characters provide diagnostic features. Our study also confirms that O. lobularis and O. tuberculata are two distinct polychromic sibling species. This study highlights the difficulties of species identification in skeleton-less sponges and, more generally, in groups where morphological characters are scarce. Adopting a multi-marker approach is thus highly suitable for these groups.

  16. A simple carbon isotope model for reconstructing prehistoric human diet.

    A compilation of experimental animal data shows that neither delta13C(collagen) nor delta13C(apatite) nor Delta13C(CO-AP) indicate diagnostic reconstructions of diet, diet energy and diet protein. In contrast, plots of delta13C(collagen) against delta13C(apatite) provide a model of three regression lines (C3, C4, and marine diet protein) where position on each line indicates the energy source (C3, C4, or mixed). Neither body size nor trophic position appears to affect these relationships. Modern free-ranging, terrestrial fauna do not fit the model perhaps because they, unlike the experimental fauna, mainly use fermentation rather than digestion during energy metabolism. Archaeological humans fall as expected based on associated floral and faunal evidence. Foraging people plot at positions expected from associated C3 fauna and plants. Those from Cahokia plot, as expected, from associated deer, nuts, and maize whereas people from nearby smaller sites plot in positions consistent with eating more fish. Agriculturists from Ontario and Grasshopper Pueblo plot consistent with dependence on fish by the former and on turkeys by the latter. In Tierra del Fuego, people from interior regions ate more terrestrial fauna, as suggested by ethnohistoric reports, than did people from the coast. In the Southwestern Cape in South Africa individuals late in the sequence have pure C3 diets whereas ones early in the sequence ate marine protein as suggested by independent archaeological evidence. People on San Nicolas Island depended on C4 plants in contrast to other islands off California's coast. This simple model provides more detailed and precise dietary information than do individual isotopic measures.

    The authors report high-precision Sr isotope of aragonitic fossils from Pleistocene marine terraces, which formed during both glacial and interglacial periods, to (1) constrain the marine Sr-isotope trend for the late Quaternary, and (2) test the long-term marine Sr-isotope trend for reversals related to glacial-interglacial transitions. Analyses of multiple samples of mollusks from each of 15 interglacial terraces on San Nicolas Island, San Clemente Island, and the Palos Verdes Hills (California) define a marine Sr-isotope trend (assigning terrace ages based on an assumption of constant long-term uplift rates calculated from the height of dated 120-Ka terraces) that is generally similar to the trend defined by the data of recent workers for DSDP samples. Data for three U-series dated interglacial terraces on the East Coast of the US plot close to the California trend, as do data for 14 coral samples of 0-750 Ka age (dated by mass-spectrometric {sup 234}U/{sup 238}U) from submerged, glacial-stage reefs off Hawaii. As a whole, their data indicate an approximately linear increase of approximately 0.05 % in {sup 87}Sr/{sup 86}Sr over the last 800 k.y., confirm the presence of a subtle ({approximately}0.01 %) reversal between approximately 900 and 600 Ka, and resolve a previously unrecognized reversal of approximately 0.02{per thousand} between approximately 1,400 and 1,200 Ka. In addition, the lack of obvious fine structure in samples younger than 800 ka indicates that the amplitude of any short-period oscillations (<100 ky.) in the marine {sup 87}Sr/{sup 86}Sr trend for the Late Quaternary is probably less than approximately 0.02{per thousand}.

    Recent program requirements of the US Department of Energy/NNSA have led to a need for a criticality accident alarm system to be installed at a newly activated facility. The Criticality Safety Group of the Lawrence Livermore National Laboratory (LLNL) was able to recover and store for possible future use approximately 200 neutron criticality detectors and 20 master alarm panels from the former Rocky Flats Plant in Golden, Colorado when the plant was closed. The Criticality Safety Group participated in a facility analysis and evaluation, the engineering design and review process, as well as the refurbishment, testing, and recalibration of the Rocky Flats criticality alarm system equipment to be used in the new facility. In order to demonstrate the functionality and survivability of the neutron detectors to the effects of an actual criticality accident, neutron detector testing was performed at the French CEA Valduc SILENE reactor from October 7 to October 19, 2010. The neutron detectors were exposed to three criticality events or pulses generated by the SILENE reactor. The first excursion was performed with a bare or unshielded reactor, and the second excursion was made with a lead shielded/reflected reactor, and the third excursion with a polyethylene reflected core. These tests of the Rocky Flats neutron detectors were performed as a part of the 2010 Criticality Accident Alarm System Benchmark Measurements at the SILENE Reactor. The principal investigators for this series of experiments were Thomas M. Miller and John C. Wagner of the Oak Ridge National Laboratory, with Nicolas Authier and Nathalie Baclet of CEA Valduc. Several other organizations were also represented, including the Y-12 National Security Complex, Lawrence Livermore National Laboratory, Los Alamos National Laboratory, CEA Saclay, and Babcock International Group.

    The recently developed general-model-space (GMS) state-universal (SU) coupled-cluster (CC) approach, together with its version corrected for triples via a single-reference (SR) CCSD(T)-type correction of the diagonal elements of the effective Hamiltonian, is applied to several molecular electronic structure problems in order to assess their performance and the role of triples. These results are compared with an alternative handling of higher-than-pair clusters via the externally corrected SU CCSD method, denoted (M, N)-CCSD, which employs N wave functions of the M-reference CISD as an external source for N-reference SU CCSD. These methods are applied to the problem of bond breaking in the ground and excited states of the F2 and HF molecules, where the high-spin triplet component is also handled via the SR CCSD method. We further examine the vertical excitation energies of water and the basic spectroscopic constants (equilibrium geometries, harmonic frequencies, and excitation energies) for several low-lying states of oxygen. The results are encouraging and are discussed from the viewpoint of the applicability and usefulness of perturbative-type triple corrections. Laudatio

    The goal of this research has been to identify and describe the properties of climatically important cloud systems critically important to understanding their effects upon satellite remote sensing and the global climate. These goals have been pursued along several different but complementary lines of investigation: the design, construction, testing and application of instrumentation; the collection of data sets during Intensive Field Observation periods; the reduction and analysis of data collected during IFO's; and completion of research projects specifically designed to address important and timely research objectives. In the first year covered by this research proposal, three papers were authored in the refereed literature which reported completed analyses of FIRE 1 IFO studies initiated under the previous NASA funding of this topic area. microphysical and radiative properties of marine stratocumulus cloud systems deduced from tethered balloon observations were reported from the San Nicolas Island site of the first FIRE marine stratocumulus experiment. Likewise, in situ observations of radiation and dynamic properties of a cirrus cloud layer were reported from first FIRE cirrus IFO based from Madison, Wisconsin. In addition, application techniques were under development for monitoring cirrus cloud systems using a 403 MHz Doppler wind profiler system adapted with a RASS (Radio Acoustic Sounding System) and an infrared interferometer system; these instrument systems were used in subsequent deployments for the FIRE 2 Parsons, Kansas and FIRE 2 Porto Santo, ASTEX expeditions. In November 1991 and in June 1992, these two systems along with a complete complement of surface radiation and meteorology measurements were deployed to the two sites noted above as anchor points for the respective IFO'S. Subsequent research activity concentrated on the interpretation and integration of the IFO analyses in the context of the radiative properties of cloud systems and our ability

    The brass plates of (50 × 10 × 1) mm3 were prepared with model corrosion layer because the real archaeological artifacts could be damaged during the method optimization. Samples corroded naturally more than 2 years in the soil. Excavated samples were treated in the low pressure (150 Pa) quartz glass plasma reactor (90 cm long and 9.5 cm in diameter) which was surrounded by two external copper electrodes supplied by radio-frequency generator (13.56 MHz). The experiments were carried out in a hydrogen-argon gas mixture at mass flows of 30 sccm for hydrogen and 20 sccm for argon for 90 min. The plasma power was 100, 200, 300 and 400 W in continuous and pulsed mode. Maximum sample temperature was set at 120 °C. The whole process was monitored by optical emission spectroscopy and the obtained data were used to calculate the relative intensity of OH radicals and rotational temperature. The results showed that the higher power had the greater maximum intensity of the OH radicals and rapidly degraded the corrosion layer. Corrosion layer was not completely removed during the reduction, but due to the reactions which occur in the plasma corrosion layer became brittle and after plasma chemical treatment can be removed easily. Finally, the SEM-EDX analysis of the surface composition confirmed removal of chlorine and oxygen from the corrosion products layers.

    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.

    Israeli farmers export 250,000 tons of potato tubers annually, ≈40,000 tons of which are harvested early, before skin set. In recent years, there has been an increase in the occurrence of dark skin spots on early-harvested potato tubers ('Nicola') packed in large bags containing peat to retain moisture. The irregular necrotic spots form during storage and overseas transport. Characterization of the conditions required for symptom development indicated that bag temperature after packing is 11 to 13°C and it reaches the target temperature (8°C) only 25 days postharvest. This slow decrease in temperature may promote the establishment of pathogen infection. Isolates from typical lesions were identified as Rhizoctonia spp., and Koch's postulates were completed with 25 isolates by artificial inoculation performed at 13 to 14°C. Phylogenetic analysis, using the internal transcribed spacer sequences (ITS1 and ITS2) of rDNA genes, assigned three isolates to anastomosis group 3 of Rhizoctonia solani. Inoculation of wounded tubers with mycelium of these R. solani isolates resulted in an oversuberization response in the infected area. With isolate Rh17 of R. solani, expression of the suberin biosynthesis-related genes StKCS6 and CYP86A33 increased 6.8- and 3.4-fold, respectively, 24 h postinoculation, followed by a 2.9-fold increase in POP_A, a gene associated with wound-induced suberization, expression 48 h postinoculation, compared with the noninoculated tubers. We suggest that postharvest dark spot disease is an oversuberization response to R. solani of AG-3 infection that occurs prior to tuber skin set.

  4. [The process of metropolizing Monterrey: there must be a long-term plan].

    PubMed

    Garza, G

    Monterrey achieved metropolitan status in the 1950s, when it expanded toward the municipios of Guadalupe and San Nicolas de los Garza. 93.6% of the total metropolitan population at that time lived in the municipio of Monterrey. Between 1950 and 1960 metropolitan Monterrey grew at an annual rate of 6.7% and the population nearly doubled. In the 1960s three other municipios were added to the metropolitan area, for a total of seven, and the share of the population living in the municipio of Monterrey dropped to 68.3%. From 1970 to 1980, metropolitan Monterrey's annual growth rate declined to 4.6%, and only one municipio was added. The municipio of Monterrey had a growth rate of 2.2%, while the surrounding municipios had rates several times higher. The process of metropolitanization decelerated considerably between 1980 and 1990, with an annual growth rate of 2.5% for the metropolitan region, the lowest since 1910-21. The municipio of Monterrey had a negative growth of -0.2% in the 1980s. Industrialization was the main determinant of metropolitan growth in Monterrey. Industrial growth was most rapid between 1950 and 1970, when 10.4% of national industry was located in Monterrey. Monterrey was seriously affected by the economic crisis of the 1980s, suffering a decline of 1.1% annually and a reduction of its share of national industry to 8.8% by 1988. If the economic recuperation of 1988-92 continues, Monterrey is projected to increase by 75% in population and 60% in urban area in the next 20 years, implying the need for tremendous infrastructural construction. Longterm planning must be carried out to minimize the problems of growth and size in Monterrey and to assure an adequate economic foundation for the metropolis.

  5. Bradley and Lacaille: Praxis as Passionate Pursuit of Exact Science

    1997-12-01

    From 1700 to 1800, astronomical observation and prediction improved in accuracy by an order of magnitude or more: by century's end astronomers could trust catalogued and predicted positions to within a few arcseconds. Crucial to this improvement were the discoveries of Bradley, which grew out of an endeavor of "normal science," the attempt to confirm with precision Robert Hooke's earlier supposed discovery of annual parallax in Gamma Draconis. On the theoretical side, Bradley's discoveries led to the quiet demise of two earlier doctrines, the Tychonic System and the Aristotelian and Cartesian doctrine of the instantaneous transmission of light. On the side of praxis, Bradley's discoveries meant that observational astronomy must be re-done from the ground up. In 1742 Nicolas-Louis Lacaille (1713-62), who had been admitted to the Paris Academie des Sciences only the year before, proposed to his astronomer colleagues that they take up this task as a cooperative enterprise. His proposal met with silence, but he undertook the project on his own, making it his life's work. By 1757 he had completed his Fundamenta Astronomiae, including a catalogue of 400 bright stars in which for the first time star positions were corrected for aberration and nutation. In 1758 he published his solar tables, the first to incorporate lunar and planetary perturbations as well as aberration and nutation. Lacaille's pendulum clock was not temperature-compensated, and his sextant poorly calibrated, but he was to some extent able to compensate for these flaws by bringing a massive number of observations to bear. Till the 1790s his Fundamenta Astronomiae and Tabulae Solares were important for the increments in accuracy they brought about, and for the inspiration they gave to later astronomers such as Delambre.

    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.

    The family Oscarellidae is one of the two families in the class Homoscleromorpha (phylum Porifera) and is characterized by the absence of a skeleton and the presence of a specific mitochondrial gene, tatC. This family currently encompasses sponges in two genera: Oscarella with 17 described species and Pseudocorticium with one described species. Although sponges in this group are relatively well-studied, phylogenetic relationships among members of Oscarellidae and the validity of genus Pseudocorticium remain open questions. Here we present a phylogenetic analysis of Oscarellidae using four markers (18S rDNA, 28S rDNA, atp6, tatC), and argue that it should become a mono-generic family, with Pseudocorticium being synonymized with Oscarella, and with the transfer of Pseudocorticium jarrei to Oscarella jarrei. We show that the genus Oscarella can be subdivided into four clades, each of which is supported by either a small number of morphological characters or by molecular synapomorphies. In addition, we describe two new species of Oscarella from Norwegian fjords: O. bergenensis sp. nov. and O. nicolae sp. nov., and we compare their morphology, anatomy, and cytology with other species in this genus. Internal anatomical characters are similar in both species, but details of external morphology and particularly of cytological characters provide diagnostic features. Our study also confirms that O. lobularis and O. tuberculata are two distinct polychromic sibling species. This study highlights the difficulties of species identification in skeleton-less sponges and, more generally, in groups where morphological characters are scarce. Adopting a multi-marker approach is thus highly suitable for these groups. PMID:23737959

    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.

  10. Dependence of marine stratocumulus reflectivities on liquid water paths

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

    1990-01-01

    Simple parameterizations that relate cloud liquid water content to cloud reflectivity are often used in general circulation climate models to calculate the effect of clouds in the earth's energy budget. Such parameterizations have been developed by Stephens (1978) and by Slingo and Schrecker (1982) and others. Here researchers seek to verify the parametric relationship through the use of simultaneous observations of cloud liquid water content and cloud reflectivity. The column amount of cloud liquid was measured using a microwave radiometer on San Nicolas Island following techniques described by Hogg et al., (1983). Cloud reflectivity was obtained through spatial coherence analysis of Advanced Very High Resolution Radiometer (AVHRR) imagery data (Coakley and Beckner, 1988). They present the dependence of the observed reflectivity on the observed liquid water path. They also compare this empirical relationship with that proposed by Stephens (1978). Researchers found that by taking clouds to be isotropic reflectors, the observed reflectivities and observed column amounts of cloud liquid water are related in a manner that is consistent with simple parameterizations often used in general circulation climate models to determine the effect of clouds on the earth's radiation budget. Attempts to use the results of radiative transfer calculations to correct for the anisotropy of the AVHRR derived reflectivities resulted in a greater scatter of the points about the relationship expected between liquid water path and reflectivity. The anisotropy of the observed reflectivities proved to be small, much smaller than indicated by theory. To critically assess parameterizations, more simultaneous observations of cloud liquid water and cloud reflectivities and better calibration of the AVHRR sensors are needed.

  11. 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.

  12. Diurnal variation in the turbulent structure of the cloudy marine boundary layer during FIRE 1987

    1990-01-01

    During the 1987 FIRE marine stratocumulus experiment the U.K. Meteorological Office operated a set of turbulence probes attached to the tether cable of a balloon based on San Nicolas Island. Typically six probes were used; each probe is fitted with Gill propeller anemometers, a platinum resistance thermometer and wet and dry thermistors, to permit measurements of the fluxes of momentum, heat, and humidity. The orientation of each probe is determined from a pair of inclinometers and a three-axis magnetometer. Sufficient information is available to allow the measured wind velocities to be corrected for the motion of the balloon. On the 14 to 15 July measurements were made over the period 1530 to 1200 UTC and again, after a short break for battery recharging and topping-up the balloon, between 0400 to 0900 UTC. Data were therefore recorded from morning to early evening, and again for a period overnight. Six probes were available for the daytime measurements, five for the night. Data were recorded at 4 Hz for individual periods of a little over an hour. The intention was to keep a minimum of one probe at or just above cloud top; small changes in balloon height were necessary to accommodate changes in inversion height. The ability of the balloon system to make simultaneous measurements at several levels allows the vertical structure of the boundary layer to be displayed without resort to composites. Turbulent statistics were calculated from 2 hour periods, one straddling local noon and one at night. These were subdivided into half-hour averaging intervals for the evaluation of variances and fluxes.

The disk feeds material to presumably an inner, unresolved accretion disk that is made up of gas entrapped by the black hole. The red blobs near the disk are glowing gas clouds which have been heated up and ionized by the powerful radiation from the active nucleus.

    Generated ozone foam was applied to the disinfection of Pseudomonas fluorescens. The effect of disinfection has been confirmed experimentally and new equipment for the disinfection of hands using this ozone foam has been put on the market for the practical use. The ozone foam was produced in the foam generator after mixing the water including surfactant (30 mL/min) and air including ozone (1000 ppm = 2.14 g/m3 ~ 1600 ppm = 3.4 g/m3, 300 mL/min). The liquid-to-gas ratio is 100 L/m3. The concentration of dissolved ozone in the thin liquid films of the bubbles was about 3 mg/L which was measured by the chemical method of the KI absorption and titration of sodium thiosulfate solution. The disinfection test samples were prepared using the PET disk on which Pseudomonas fluorescens of its number of more than 108 were attached. Test sample was inserted into ozone foam set on the glass plate for one to 6 min. The survival rate log (N/N0 decreased with time and its value of about-2.6 (i.e., ~1/400) was obtained at 6 min (2 min × 3 times repeated). It was also confirmed that the ozone foam was useful for the disinfection of hands. For more effective disinfection (in case of taking a long time for foam melting), the ozone foam was broken by force and changed into ozone water by which the survival rate decreased ×4 (i.e., N/N0 = 1/10 000) at 4 ~ 6 min.

  15. Anisotropy of thermal contraction controls deep hydrothermal circulation at oceanic ridges

    NASA Astrophysics Data System (ADS)

    2003-04-01

    A deep and high-T (up to 1000^oC) hydrothermal contamination of the oceanic crust at the ridge axis has been documented in the Oman ophiolite. In the deep and hot gabbros, the main water channels are submillimetric microcracks with a dominantly vertical attitude (Nicolas et al, in press). Sr and O isotopic investigations point to seawater as the most likely hydrothermal contaminant (Bosch et al. submitted). We propose that the mechanism allowing seawater ingression at temperatures above 700^oC is anisotropy of thermal contraction, opening microcracks that are controlled by fabric. The exceptionally large anisotropy of thermal contraction of single crystal of calcic plagioclase, when introduced in the strong lattice fabrics in the lower gabbros results in finding the maximum thermal contraction direction parallel to maximum crystals elongation L1. This direction in the oceanic ridge referential is horizontal and perpendicular to microcracks dominant orientation. This high-T hydrothermal alteration in gabbros reaches the Moho. In the underlying peridotites, preliminary Sr isotopic data on clinopyroxene from wehrlites suggest that seawater was able to ingress at crystallization temperature for clinopyroxene. Interestingly, in these peridotites with horizontal foliation, thermal contraction, calculated as above from fabrics and thermal expansion coefficients in olivine, is vertical, being responsible for subhorizontal cracking, as deduced from serpentine dominant veining. Thus, during off-axis drifting of newly accreted lithosphere, thermal contraction opens vertical cracks, favoring seawater ingression down to the Moho. Below, in peridotites, the horizontal microcrack system would favor closing of hydrothermal circuit at Moho level.

    Jean Rey, a physician from The Bugue, a little town near Bergerac, published, in 1630, a book entitled "Essays" in which he explained the increase of the mass of lead, when it was strongly heated, by the fixation of a part of the air. This revolutionary publication was not received by the European scientists, because the Father Mersenne, "the secretary of learned Europe", was not able to repeat his experiments. Between 1774 and 1775, Pierre Bayen, who was a military apothecary, published his Works concerning the "precipitate per se", for us HgO, showing that when this compound was destroyed by heating, it produced a gas, and that the mass of this gas and the mass of the mercury obtained were equal to the mass of the "precipitate per se". He concluded that the phlogiston theory was contradictory with the results of the experiments. When, later on, Lavoisier published his important article on the increase of the mass of steal when it was heated in the air, he "forgot" to cite the Works of Bayen. In January 1775, Pierre Bayen published a letter in which he mentioned that he had discovered an exemplar of Jean Rey's book and explained that this physician of the 17th century had supposed the explanation that had been proved by Lavoisier. Nicolas Gobet then published a new edition of the "Essays" in 1777, but this new edition became itself quite rare. An inscription pencilled on the book kept by the British Museum pretends that all the exemplars Lavoisier could find were destroyed. It is not rigorous to conclude on a single document, especially when it is not signed, but it is sufficient to induce doubt.

  17. Zircon U-Pb geochronology and heavy mineral composition of the Camaná Formation, southern Peru: Constraints on sediment provenance and uplift of the Coastal and Western Cordilleras

    In the forearc of the Central Andes of southern Peru, the Cenozoic Camaná Basin (16°25‧S to 17°15‧S) forms a ∼NW-SE elongated depression filled with coarse-grained deltaic and fluvial deposits. These deposits are termed Camaná Formation. We have applied for the first time, advanced multi-method analytical techniques to sediments of the Camaná Formation in order to define precise sedimentation ages, unravel sediment provenance, and to explain its tectono-sedimentary evolution. Zircon U-Pb geochronology and multiple geological evidences suggest that the Camaná Formation ranges in age from Late Oligocene to Late Miocene, and may even extend into the Pliocene. We propose a provenance model for the Camaná Formation based on U-Pb geochronology, heavy mineral analysis, and single-grain mineral chemistry by LA-ICP-MS. This model suggests that sediments of the lower part of the Camaná Formation derive from rocks forming the Coastal Cordillera (i.e. the Arequipa Massif and the San Nicolas Batholith) and the widespread ignimbrites of the ∼24-10 Ma Huaylillas volcanic arc. In contrast, sediments of the upper part of the Camaná Formation derive predominantly from rocks forming the Western Cordillera (i.e. the Arequipa Massif, the Tacaza Group, and the Coastal Batholith) and products of the ∼10-3 Ma Lower Barroso volcanic arc). Accordingly, we infer that uplift of the Coastal Cordillera has strongly influenced deposition of the Camaná Formation since Late Oligocene. A marked shift in provenance within the Camaná Formation at around Middle to Late Miocene time (14-12 Ma) suggests drastic uplift of the Western Cordillera at that time. This uplift has triggered increased relief and erosion in the Western Cordillera, and subsequent deposition of fluvial conglomerates in the Camaná Basin.

    Super trajectory is reported of tobacco from his first meeting with the European man October 15, 1492. This plant was known in Europe by the publications of the Sevillan physician Nicolas Monardes (1574), the relations of friar Andrés Thevet (1575) and the famous botanical treatise of Charles de l'Écluse (1605). The Swedish botanist Karl Linnaeus inclused tobacco plant in the family Solanaceae and deleted from this group other plants that were intermixed with it. Its botanical name (Nicotiana tabacum) derived from the surname of the French ambassador to Portugal, Jean Nicot of Villemain, who in 1560 sent it to the Queen Mother of France Cathérine de Medicis. The use of snuff quickly spread throughout Europe, were it became common in the seventeenth century. By the late eighteenth century in New Spain, in addition to cigars, cigarettes and due in packs of different content the tobacco is concocted and price. The preparation of the different presentations of snuff, tobacco made in factories in the capital and several provincial cities, originated in 1796 the creation of the first kindergartens for the children of those working in them. This thanks to the successful initiative of then viceroy Marquis of Branciforte. But contrary to the forecasts of Father F. J. Clavijero and Mrs. F. Calderón de la Barca, wife of the first Spanish diplomatic representative to the government of Mexico, the use of tobacco, with the passage of time, far from waning has been increasing in every social class. And now, more than men, women are smokers.

    In the last twenty-five years more has been learned about the human brain than in the past history of mankind. Through the use of new technologies such as PET and CAT scans and functional MRI's, it is now possible to see and learn much about the human brain while it is in the process of thinking. The research of neuroscientists, such as Marian Diamond, has demonstrated that the brain changes physiologically as a result of learning and experience--for better or worse--and that plasticity can continue throughout the lifespan. It appears that there are particular kinds of environments that are most conducive to the development of good mental equipment. They are positive, nurturing, stimulating, and encourage action and interaction. Many of the most effective schools and training programs have created such high-challenge low-threat environments. It is also very clear that intelligence is not a static structure, but an open, dynamic system that can continue to develop throughout life. This understanding is being utilized not only in school systems but in the workplace, where training programs show that even at the adult level people are able to develop their intelligence more fully. Corporations such as Motorola have implemented programs in which they are training their employees, managers, and executives to think, problem-solve and create more effectively using strategies developed by such educational innovators as Reuven Feurstein, J.P. Guilford, and Edward de Bono. A most recent development is in the new kinds of technology that make it possible for people to take responsibility for their own learning as they access and process information through the internet, communicate with experts anywhere in the world, and use software that facilitate higher order thinking and problem-solving. Computers are in no way replacing teachers, but rather these new tools allow them to spend more time being facilitators, mentors, and guides. As a result, teachers and students are able

Reconstructions based on these poles predict that at ˜ 45 Ma the Palau-Kyushu Ridge had a WNW-ESE orientation which is very different from that postulated by many models used to explain the widespread boninite volcanism in the Izu-Bonin-Marians forearc at this time. The long arc history of the southern part of the plate and the reconstructions based on the rotation poles calculated from the palaeomagnetic data favour an origin for the West Philippine Basin by spreading in a backarc basin.

    The unusual incidence patterns for nasopharyngeal carcinoma (NPC) in China, Northeast India, Arctic Inuit, Peninsular and island Southeast Asia, Polynesian Islanders, and North Africans indicate a role for NPC risk genes in Chinese, Chinese-related, and not-obviously Chinese-related populations. Renewed interest in NPC genetic risk has been stimulated by a hypothesis that NPC population patterns originated in Bai-Yue / pre-Austronesian-speaking aborigines and were dispersed during the last glacial maximum by Sundaland submersion. Five articles in this issue of the Chinese Journal of Cancer, first presented at a meeting on genetic aspects of NPC [National Cancer Center of Singapore (NCCS), February 20-21, 2010], are directed towards incidence patterns, to early detection of affected individuals within risk populations, and to the application of genetic technology advances to understanding the nature of high risk. Turnbull presents a general framework for understanding population migrations that underlie NPC and similar complex diseases, including other viral cancers. Trejaut et al. apply genetic markers to detail migration from East Asia through Taiwan to the populating of Island Polynesia. Migration dispersal in a westward direction took mongoloid peoples to modern day Northeast India adjacent to Western China (Xinjiang). NPC incidence in mongoloid Nagas ranks amongst the highest in the world, whereas elsewhere in India NPC is uncommon. Cao et al. detail incidence patterns in Southeast China that have occurred over recent decades. Finally, Ji et al. describe the utility of Epstein-Barr virus serostatus in early NPC detection. While genetic risk factors still remain largely unknown, human leukocyte antigen (HLA) genes have been a focus of attention since the discovery of an HLA association with NPC in 1973 and, two years later, that NPC susceptibility in highest-risk Cantonese involved the co-occurrence of multi-HLA locus combinations of HLA genes as chromosome

    Purpose: To determine dosimetric impact of positioning errors in the stereotactic hypo-fractionated treatment of intracranial lesions using 3Dtransaltional and 3D-rotational corrections (6D) frameless BrainLAB ExacTrac X-Ray system. Methods: 20 cranial lesions, treated in 3 or 5 fractions, were selected. An infrared (IR) optical positioning system was employed for initial patient setup followed by stereoscopic kV X-ray radiographs for position verification. 6D-translational and rotational shifts were determined to correct patient position. If these shifts were above tolerance (0.7 mm translational and 1° rotational), corrections were applied and another set of X-rays was taken to verify patient position. Dosimetric impact (D95, Dmin, Dmax, and Dmean of planning target volume (PTV) compared to original plans) of positioning errors for initial IR setup (XC: Xray Correction) and post-correction (XV: X-ray Verification) was determined in a treatment planning system using a method proposed by Yue et al. (Med. Phys. 33, 21-31 (2006)) with 3D-translational errors only and 6D-translational and rotational errors. Results: Absolute mean translational errors (±standard deviation) for total 92 fractions (XC/XV) were 0.79±0.88/0.19±0.15 mm (lateral), 1.66±1.71/0.18 ±0.16 mm (longitudinal), 1.95±1.18/0.15±0.14 mm (vertical) and rotational errors were 0.61±0.47/0.17±0.15° (pitch), 0.55±0.49/0.16±0.24° (roll), and 0.68±0.73/0.16±0.15° (yaw). The average changes (loss of coverage) in D95, Dmin, Dmax, and Dmean were 4.5±7.3/0.1±0.2%, 17.8±22.5/1.1±2.5%, 0.4±1.4/0.1±0.3%, and 0.9±1.7/0.0±0.1% using 6Dshifts and 3.1±5.5/0.0±0.1%, 14.2±20.3/0.8±1.7%, 0.0±1.2/0.1±0.3%, and 0.7±1.4/0.0±0.1% using 3D-translational shifts only. The setup corrections (XC-XV) improved the PTV coverage by 4.4±7.3% (D95) and 16.7±23.5% (Dmin) using 6D adjustment. Strong correlations were observed between translation errors and deviations in dose coverage for XC. Conclusion

    Palaeoglaciological and palaeoclimate reconstructions of the deglaciation of the last Cordilleran Ice Sheet (CIS) over British Columbia (BC), Canada, are limited by the relative lack of understanding of the late-glacial ice sheet margins and dynamics. Deglaciation of the last CIS over the southern Interior Plateau of BC has been characterised as proceeding via stagnation and downwasting into dead ice lobes in valleys where ice was thickest. This conceptual model explains the apparent lack of moraines, which may otherwise imply active recession, and known palaeo-glacial lakes are explained as being dammed by these dead ice lobes. However, downwasting alone is at odds with coeval ice sheets which receded systematically towards their interiors. Presented here is a comparison between a new field-based reconstruction of the deglaciation of the northern Thompson Plateau, and ice sheet model results of the same area. Glacioisostatic tilts, reconstructed using mapped shoreline elevations, rise to the north-northwest at around 1.8 m/km, implying an ice surface slope, and likely active recession, towards the Coast Mountains. New reconstructions of the stages of glacial Lake Nicola (gLN), utilising field and aerial photographic mapping of shorelines, and sedimentology and geophysical surveys on ice-marginal and glaciolacustrine landforms, largely support this interpretation; the lake expanded and lowered to the north-northwest as progressively lower outlets were opened during ice retreat in this direction. Fields of newly discovered glaciotectonised moraines, grounding-line deposits and overridden glacial lake sediments record ice margin oscillations and minor readvances within gLN; the general alignment of these features further supports recession to the north-northwest. Numerical simulations of deglaciation of the area results in ice retreat to the north-northeast, which is inconsistent with the north-north-westward evolution of gLN. Excess precipitation over the eastern

    On July 1, 1751, the royal Parisian printer Le Breton published the first volume of the Encyclopédie of Diderot and d'Alembert, a rational dictionary, in folio and in alphabetical order, sold by subscription. The whole work was completed in 1780 (a total of 35 volumes, of which 12 were of illustrations, 4 of supplements and 2 of indices). In 1782 it was followed by the Encyclopédie méthodique, printed by Panckoucke, which ended in 1832 with volume number 166. The frontispiece of the first volume, designed by Charles-Nicolas Cochin Jr. and engraved by Benoît-Louis Prévost showed the columns of an Ionic temple where the Truth appears between Reason and Philosophy. Reason is shown trying to break the veil of Truth, and Philosophy trying to embellish it. Below are the philosophers, their eyes fixed on Truth. Theology is on his knees with his back facing Truth, and seems to receive light from the top. The subsequent chain of figures depicts Memory, Ancient History, Modern History, Geometry, Astronomy and Physics. Below are Optics, Botany, Chemistry and Agriculture. On the bottom line one finds the representatives of arts and professions derived from science. In a 42-page preface ("Discours préliminaire") d'Alembert discussed the path to new knowledge as one "based on what we receive through senses. Ideas depend on senses." The medical collaborators were, or became, famous. Medicine was considered to be rooted in experiment, in patients and in measurements. Functions started to be described with numbers. It was the birth of determinism which was later reinforced by Magendie and Claude Bernard. Albrecht Haller, president of the Academy of Science at Göttingen, as well as a member of all European academies, wrote seminal entries. New accurate definitions appeared for life, disease, death, infections, plague, epidemics, hygiene, fevers and edema. Semiology, the study of signs, became the visible explanation of deranged function, diagnosis and prognosis.

Serbia suffered human casualties, huge infrastructure and industrial destruction and agricultural damage. Cyclone development and trajectory was very well predicted by RHMSS operational WRF NMM numerical model but extreme precipitation was not possible to predict with sufficient precision. Simulation of extreme rainfall situations using different numerical weather prediction models can indicate weakness of the model and point out importance of specified physical approach and parameterization schemes. The FP7 Distributed Research Infrastructure for Hydro-Meteorology DRIHM project gives a framework for using different models in forecasting extreme weather events. One of the DRIHM component is Rainfall Filtered Autoregressive Model RainFARM for stochastic rainfall downscaling. Objective of the DRIHM project was developing of standards and conversion of the data for seamless use of meteorological and hydrological models in flood prediction. This paper describes numerical tests and results of WRF NMM nonhydrostatic model and RainFARM downscaling applied on WRF NMM outputs. Different physics options in WRF NMM and their influence on precipitation amount were investigated. RainFARM was applied on every physical option with downscaling from 4km to 500m and 100m horizontal resolution and 100 ensemble members. We analyzed locations on the catchments in Serbia where flooding was the strongest and the most destructive. Statistical evaluation of ensemble output gives new insight into the sub scale precipitation

    Increasing gas flow through a bed of particles produces, above a sharp threshold, a fluidized state which exhibits many of the properties of a liquid. Fluidized beds play a major role in refining, chemicals, and power generation, but the physics of the fluidized state is still uncertain, due to the complexity of the particle/gas interactions, the broad distribution of particle size, and the measurement challenge. One consequence can be the failure of sophisticated computer models to predict performance. Another is the failure to resolve fundamental questions, for example the source of the initial stability/instability of the uniform fluidized state, first addressed by Jackson in 1963(R. Jackson, in Fluidization, edited by J. F. Davidson et al. (Academic Press, New York, 1985), p. 47-72; G. K. Batchelor, J. Fluid Mech. 193, 75-110 (1988); M. Nicolas. J. Chomaz, and E. Guazelli, Phys. Fluids 6, 3936-3944 (1994).). To meet the measurement challenge, we have obtained the first comprehensive data on the mean squared fluctuation velocity, or granular temperature, T*, of monodispersed glass spheres of diameter, D, in a fluidized bed, by a novel acoustic shot noise probe of random particle impact on the wall(G. D. Cody, D. J. Goldfarb, G. V. Storch, Jr., A. N. Norris, Powder Technology 87, 211-232 (1996); G. D. Cody and D. J. Goldfarb, in Dynamics in Small Confining Systems-III, eds. M. Drake et al, (MRS, Pittsburgh, Pa, 1997), 464, p. 325-338.). Applying a dense gas kinetic model(D. Gidaspow, Multiphase Flow and Fluidization (Academic Press, San Diego, 1994).) to this data predicts values of particulate pressure, and viscosity, which are in excellent agreement with recent experiments, and encouraged us to revisit the stability question. We find that the unanticipated seven-fold bifurcation observed in T* for D less than 150 microns is sufficient, using Jackson's model, to account for the accepted empirical boundary of stable initial uniform fluidization for the spheres

    Late Holocene (240 km2 on the east side of the volcano with >25 cm of tephra. Lavas from eruptive sequence I dammed drainage in the lowland area near the town of San Nicolas and caused local upstream deposition of as much as 30 m of lacustrine silts, clays, and sands. These lacustrine deposits record an eruptive hiatus for the Tetimpa area of about 750 14C yr: between ca. 2100 and ca. 1350 yr B.P., no major tephras were deposited in the Tetimpa area. In upland areas, this time period is represented by an unconformity and by Entisols formed in the top of pumice deposits and lavas from eruptive sequence I. Artifacts, agricultural furrows, and dwellings record human reoccupation of this surface. At the end of this hiatus, several lahars were deposited above the lacustrine sequence and locally above the Entisol in upland positions adjacent to streams. Between ca. 1350 and ca. 1200 yr B.P., tephras from eruptive sequence II buried these paleosols, occupation sites, lacustrine sediments, and lahars. Andesitic (~62% SiO2) pumice lapilli deposits in the Tetimpa area record three pumice-fall eruptions directed northeast and east of the crater. The first and smallest of these (maximum Tetimpa area thickness = 12 cm; >52 km2 covered by >25 cm) took place at ca. 1350 yr B.P. and was accompanied by pyroclastic surge events preserved in the Tetimpa area by charcoal, sand waves, and cross-stratified sand-sized tephra. At ca. 1200 yr B.P., the products of two Plinian-style events and additional pyroclastic surges reached the Tetimpa area. The largest of these tephra-fall events covered the Tetimpa area with 0.5-1 m of tephra and blanketed an area of >230 km2 with a thickness of >25 cm. The Tetimpa record confirms two of the four periods of explosive volcanism recognized by studies conducted around Popocatepetl in the past 30 yr. Eruptive sequence I corresponds to the explosive period between 2100 and 2500 yr B.P., and eruptive sequence II corresponds to the period between 900 and

    Made in the frame of a French master on political history of USA in Paris IV La Sorbonne University, this subject is the third part of " The Economy of Apollo during the 60s". Nicolas Turcat is actually preparing his PhD in History of Innovation (DEA—Paris IV La Sorbonne). Our actual subject is " the link between aerospace industry and NASA during the Apollo years". This speech will highlight on some aspects of the link between NASA and aerospace industry. NASA could achieve the Apollo mission safely and under heavy financial pressure during the sixties due to a new type of organization for a civil agency; the contractor system. In fact, Military used it since the 1950s. And we will see how the development of this type of contract permitted a better interaction between the two parts. NASA would make another type of link with universities and technical institutes; a real brain trust was created, and between 1961 and 1967, 10,000 students worked and more than 200 universities on Apollo program. We will try to study briefly the procurement plan and process during the Apollo years. Without entering the " spin-offs debate", we will try to watch different aspects of the impacts and realities of the contractor and subcontractor system. We will see that would create a political debate inside USA when presidents Johnson and Nixon would decide to reduce Apollo program. Which states will benefit Apollo program? Or questions like how the debate at the end of the 1960s will become more and more political? Actually, almost 60% of the country's R&D was focused on Apollo, economical and moreover, political impacts would be great. We will try to study this under the light of different example: and particularly in California. The industrial and military complex was a part of the Apollo program. Apollo reoriented the aim of this complex for making it the first aerospace industry. Since this time, USA had not only acquired space ambition but real space capabilities. But more than

    On 7th March 2005, prolonged rainfalls combined with snowfalls activated a wide complex rock slide-earth flow that partly destroyed the village of Cavallerizzo at Cerzeto (Calabria, Southern Italy). Superposed tectonic units made of Palaeozoic metamorphic rocks, overlain by Miocene-Quaternary clastic terrains, crop out in the study area. The main scarp of the landslide developed by a recent normal fault, striking N-S along the western margin of the Crati graben and extended ca. 25 km. In its lower part, the phenomenon evolved in two main earth-flow bodies that extended along minor drainages and then merged along the S. Nicola torrent. The sector affected by the instability actually belongs to a large-scale slope movement: the 2005 activation was in fact only a paroxysmal episode of a long history of slope deformations, noticed in the area since the XVIII century. Warning signs had been recorded for weeks before the collapse, and the threatened area had been put under monitoring by CNR-IRPI. When the movement accelerated, people had already been alerted and evacuated (329 out of 581 inhabitants of Cerzeto were sheltered in nearby villages), thus neither victims nor injured were recorded. As a whole, 124 buildings were severely damaged or destroyed, the main road was interrupted. Immediately after the 7th March 2005 event, the national Department for Civil Protection decided to evaluate the feasibility of delocalizing Cavallerizzo to another site. At this purpose, CNR-IRPI was asked to analysing the "geological suitability" of 3 different sites (Pianette, Amatine, and Colombra), pre-selected by the same Municipality of Cerzeto in accordance to the Civil Protection; the results of the study were completed in early Summer 2005. Between October 2007 and December 2011, a new settlement was realized by the Italian Government, and the houses were delivered to people once living at Cavallerizzo. In the last years, the socio-economic effects of the delocalization of

    Since the most ancient times the problem of the artificial preservation of dead bodies has been an important object of study. In ancient and classic times the reasons leading to this practice were essentially of a religious and esoteric type, but in the modern age, following the development of medical and biological studies, embalming has assumed a more practical trend which is both medicine and scientific. The discovery of blood circulation has marked the scientific method which, in its various forms, has circulated all over Europe bringing fame to eminent anatomists such as Federico Ruysch (1638-1731), William (1718-1783) and John Hunter (1728-1793), Jean Nicolas Gannal (1791-1852), Giuseppe Tranchina, Laskowky and Brosch, who affirmed the embalming by endoarterial injection of conservation fluids making evisceration useless and obsolete. The advent of formalin and the introduction of new surgical and autoptic methods have made this practice gradually fall into disuse. For this reason, the mummy found in Leghorn (Tuscany, Central Italy) is of particular importance since was obtained applying the intravascular injection following the method, described by the Italian medical Giuseppe Tranchina in 1835. The mummified body belongs to Gaetano Arrighi, a prisoner in the Leghorn fortress. He was born in Arezzo in 1789 and died on March 1836 at the age of 47 in the Civil Hospital of Leghorn following pleurisy, as results in an annexed document. The day after his death Dr. Raimondo Barsanti from Pisa and Superintendent at the Leghorn hospital made up the Tranchina's method, which consisted in the injection of an arsencial -mercury solution inside of the blood vessels, giving rigidity and dark red color to the dead body. The excellent outcome of the intervention has made it possible, more than 160 years later, to study not only the method by which Arrighi's body was embalmed but also to perform a careful paleopathological imaging study by traditional X-rays and by Computer

    This arcticle summarizes what could be learned from newly discovered documents about the biography of Nicolas von Vicken, first known reader of Kepler's "Astronomia Nova" and Kepler's partner in an exchange of more than a dozen letters over several years. Von Vicken stems from a rich and influential family of merchants in Riga, made noble by the Polish King (who ruled Riga at the time) in 1580. His education included legal studies at the universities of Königsberg, Leipzig and Rostock, partially overlapping with a stay of ten years at the Polish court. There von Vicken pursued family business but also served in an official court role. In 1600/1 von Vicken switched sides and started to serve the Swedish ruler (and later king) Duke Carl IX, who was at war with Poland to gain control over Riga and Livonia. In 1602 a mission for Sweden to Northern Germany brought him in conflict with Francis II, Duke of Saxe-Lauenburg, who accused von Vicken of withholding money from him, which was supposed to be used for hiring troops. Von Vicken, together with his brother Heinrich, was imprisoned, but could flee. During a mission to Maximilian III, Archduke of Austria, in 1599/1600 von Vicken had been initiated as an alchemist and astrologer through reading the works of Paracelsus and his future stations in life were influenced by this. These include an attempt to get employed at the Saxon court in Dresden, and stays in Wolfenbiittel and Halberstadt, both ruled by Duke Henry Julius of Brunswick-Lüneburg. Von Vicken offered various astrological and alchemical services to the Duke and private investors. With one of them he got into a serious conflict over the alleged non-fillment of a contract to produce steel in an alchemical way. During that von Vicken got imprisoned twice, in 1609 and between 1611 and 1614. A subsequent attempt to get employed by Ernst of Schaumburg left us with several letters that detail von Vicken's alchemical and astrological thinking, two of these are

    The direct detection of Earth-like exoplanets orbiting nearby stars and the characterization of such planets-particularly, their evolution, their atmospheres, and their ability to host life-constitute a significant problem. The quest for other worlds as abodes of life has been one of mankind's great questions for several millennia. For instance, as stated by Epicurus approximately 300 BC: "Other worlds, with plants and other living things, some of them similar and some of them different from ours, must exist." Demokritos from Abdera (460-370 BC), the man who invented the concept of indivisible small parts-atoms-also held the belief that other worlds exist around the stars and that some of these worlds may be inhabited by life-forms. The idea of the plurality of worlds and of life on them has since been held by scientists like Johannes Kepler and William Herschel, among many others. Here, one must also mention Giordano Bruno. Born in 1548, Bruno studied in France and came into contact with the teachings of Nicolas Copernicus. He wrote the book De l'Infinito, Universo e Mondi in 1584, in which he claimed that the Universe was infinite, that it contained an infinite amount of worlds like Earth, and that these worlds were inhabited by intelligent beings. At the time, this was extremely controversial, and eventually Bruno was arrested by the church and burned at the stake in Rome in 1600, as a heretic, for promoting this and other equally confrontational issues (though it is unclear exactly which idea was the one that ultimately brought him to his end). In all the aforementioned cases, the opinions and results were arrived at through reasoning-not by experiment. We have only recently acquired the technological capability to observe planets orbiting stars other than 6 our Sun; acquisition of this capability has been a remarkable feat of our time. We show in this introduction to the Habitability Primer that mankind is at the dawning of an age when, by way of the

We determine the tropospheric vertical column densities (VCDs), near surface concentrations and vertical profiles of aerosols, NO2, SO2, HCHO from the MAX-DOAS observations using the optimal estimation profile retrieval algorithm (refered to as "PriAM"). We verified the results by comparing them with results from independent techniques, such as sun photometer (AERONET), a visibility meter and a long-path DOAS instrument. We acquire the cloud and aerosol conditions using a cloud classification scheme based on the MAX-DOAS observations (Wang et al., AMTD, 2015). Based on the obtained results, we characterize the effect of the clouds on the trace gas and aerosol profiles retrieved from MAX-DOAS. Then we characterize the diurnal, annual and weekly variations of the trace gases and aerosols and validate the tropospheric trace gas VCDs derived from the Ozone Monitoring instrument (OMI) on the Aura satellite platform as well as the model results from the IMAGES, CHIMERE and Lotos-Euros models and analyse the agreement depending on the cloud and aerosol conditions. Besides the direct comparison with the satellite data, we also use the trace gas and aerosol profiles derived from MAX-DOAS to recalculate the air mass factor (AMF) for the satellite observations and to evaluate the corresponding improvement of the satellite VCDs. In some periods with strong aerosol pollution, we evaluate the

    forward the conclusion that this evolutionary scenario has been possible through a complex interplay between adaptive mutations, often structurally destabilizing, and compensatory mutations. Our results unearth patterns of evolution that have likely optimized the Rubisco activity and uncover mutational dynamics useful in the molecular engineering of enzymatic activities.

    The direct detection of Earth-like exoplanets orbiting nearby stars and the characterization of such planets -- particularly, their evolution, their atmospheres, and their ability to host life -- constitute a significant problem. The quest for other worlds as abodes of life has been one of mankind's great questions for several millennia. For instance, as stated by Epicurus 300 BC: Other worlds, with plants and other living things, some of them similar and some of them different from ours, must exist. Demokritos from Abdera (460-370 BC), the man who invented the concept of indivisible small parts - atoms - also held the belief that other worlds exist around the stars and that some of these worlds may be inhabited by life-forms. The idea of the plurality of worlds and of life on them has since been held by scientists like Johannes Kepler and William Herschel, among many others. Here, one must also mention Giordano Bruno. Born in 1548, Bruno studied in France and came into contact with the teachings of Nicolas Copernicus. He wrote the book De l'Infinito, Universo e Mondi in 1584, in which he claimed that the Universe was infinite, that it contained an infinite amount of worlds like Earth, and that these worlds were inhabited by intelligent beings. At the time, this was extremely controversial, and eventually Bruno was arrested by the church and burned at the stake in Rome in 1600, as a heretic, for promoting this and other equally confrontational issues (though it is unclear exactly which idea was the one that ultimately brought him to his end). In all the aforementioned cases, the opinions and results were arrived at through reasoning <80><94>not by experiment. We have only recently acquired the technological capability to observe planets orbiting stars other than 6our Sun; acquisition of this capability has been a remarkable feat of our time. We show in this introduction to the Habitability Primer that mankind is at the dawning of an age when, by way of the
