Vocative intonation preferences are sensitive to politeness factors.

PubMed

Borràs-Comes, Joan; Sichel-Bazin, Raféu; Prieto, Pilar

2015-03-01

Although intonation has been traditionally associated with the expression of attitudes and intentions on the part of the speaker, little is known about whether sociopragmatic factors, such as power or social distance, or situational ones, like physical distance or insistence, can constrain the use and felicity of pitch contours. This article investigates the felicity conditions underlying the choice of three vocative pitch contours in Central Catalan by means of two experiments, namely a production experiment based on the Discourse Completion Task (320 vocative contours produced by 20 speakers), and an acceptability judgment task in which 72 listeners were asked to rate the appropriateness match between a set of vocative contours and a previous discourse context (3,456 responses). The results from the two experiments show that both situational and social politeness factors govern the choice of vocative intonation. Finally, the results are discussed in line with the traditional classification of politeness strategies defined by Brown and Levinson, in the sense that the three intonation contours can be linked to negative, positive, and bald on-record politeness strategies.

Yoon, Dong-Jin; Park, Philip; Jung, Juong-Chae; Lee, Seung-Seok

2002-06-01

This study was aimed at developing a new method for assessing the integrity of concrete structures. Especially acoustic emission technique was used in carrying out both laboratory experiment and field application. From the previous laboratory study, we confirmed that AE analysis provided a promising approach for estimating the level of damage and distress in concrete structures. The Felicity ratio, one of the key parameter for assessing damage, exhibits a favorable correlation with the overall damage level. The total number of AE events under stepwise cyclic loading also showed a good agreement with the damage level. In this study, a new suggested technique was applied to several concrete bridges in Korea in order to verify the applicability in field. The AE response was analyzed to obtain key parameters such as the total number and rate of AE events, AE parameter analysis for each event, and the characteristic features of the waveform as well as Felicity ratio analysis. Stepwise loading-unloading procedure for AE generation was introduced in field test by using each different weight of vehicle. According to the condition of bridge, for instance new or old bridge, AE event rate and AE generation behavior indicated many different aspects. The results showed that the suggested analyzing method would be a promising approach for assessing the integrity of concrete structures.

Acoustic emission of retrofitted fiber-wrapped columns

NASA Astrophysics Data System (ADS)

El Echary, Hazem; Mirmiran, Amir

1998-03-01

In recent years, fiber-wrapping technique has become increasingly popular for retrofitting of existing bridge pier columns in seismic zones. By the way of confinement, the external jacket enhances strength, ductility and shear performance of the column. However, since state of the concrete core is not visible from outside of the jacket, it is of great necessity to develop proper non-destructive methods to evaluate structural integrity of the column. Extensive research on FRP-confined concrete at the University of Central Florida has shown that failure of such hybrid columns is often accompanied by considerable audible and sub-audible noise, making acoustic emission (AE) a viable NDE technique for retrofitted columns. Acoustic emission from fiber-wrapped concrete specimens were monitored. A total of 24 concrete specimens with two types of construction (bonded and unbonded) and four different number of layers (1, 3, 5 and 7) were tested under uniaxial compression. All specimens were made of S-glass fabric and polyester resin with a core diameter of 6' and a length of 12'. Some of the specimens were subjected to cycles of loading and unloading to examine the presence of the Kaiser and the Felicity effects. A 4-channel AEDSP-32/16 (Mistras-2001) machine from Physical Acoustics Corp. was used for the experiments. Results indicate that AE energy and the number of AE counts can both be good representatives for the response of confined concrete. Further, plots of AE energy versus load follows the same bilinear trend that has been observed in the stress-strain response of such specimens. Finally, Felicity effect was observed in all composite specimens.

Western municipal water conservation policy: The case of disaggregated demand

NASA Astrophysics Data System (ADS)

Burness, Stuart; Chermak, Janie; Krause, Kate

2005-03-01

We investigate aspects of the felicity of both incentive-based and command and control policies in effecting municipal water conservation goals. When demand can be disaggregated according to uses or users, our results suggest that policy efforts be focused on the submarket wherein demand is more elastic. Under plausible consumer parameters, a household production function approach to water utilization prescribes the nature of demand elasticities in alternative uses and squares nicely with empirical results from the literature. An empirical example illustrates. Overall, given data and other informational limitations, extant institutional structures, and in situ technology, our analysis suggests a predisposition for command and control policies over incentive-based tools.

We present measurements of the velocity distribution of electrons emitted from mass-selected neutral fullerenes, performed at the intracavity free electron laser FELICE. We make use of mass-specific vibrational resonances in the infrared domain to selectively heat up one out of a distribution of several fullerene species. Efficient energy redistribution leads to decay via thermionic emission. Time-resolved electron kinetic energy distributions measured give information on the decay rate of the selected fullerene. This method is generally applicable to all neutral species that exhibit thermionic emission and provides a unique tool to study the stability of mass-selected neutral clusters and molecules that are only available as part of a size distribution.

The author describes the current health state of the Hungarian population in terms of cancer mortality and morbidity. Based on the comparative analysis of national and international, mainly European, data he describes the unfavourable Hungarian indices trying to identify their causes and the possible breaking free from them, as well. The greatest potential lies in the organised, continuous screenings within the frame of "Johan Béla National Programme of the Decade of Health". Since tumour diseases pose severe and alarming problems in national health care the reduction of extremely high mortality in three tumour localisation (cervix uteri, breast and colorectum) by regular screenings is absolutely justified.

Novel iso-d-2',3'-dideoxythianucleoside derivatives 1-4 were designed and asymmetrically synthesized as a bioisostere of lamivudine to search for new anti-HIV agents. The information about using sulfur participation occurred on DAST fluorination and Mitsunobu reaction will be of great help in synthesizing sulfur-containing compounds. Final compounds 1-4 were evaluated against HIV-1 and 2, HSV-1 and 2, EMCV, Cox. B3, VSV, FluA (Taiwan), FluA (Johan.), FCV, and FIP. Only cytosine analogue 3 showed a potent anti-VSV activity (EC(50)=9.43microg/mL). This result implies that iso-2',3'-dideoxy sugar templates might play a role of a sugar surrogate of nucleosides for the development of anti-RNA virus agent.

The validity was tested against the criterion measure of 200 m track-and-field (track-and-field athletes, n = 8) and 20 m shuttle run endurance test (female soccer players, n = 20). Intra-unit and inter-unit reliability was tested by intra-class correlation coefficient (ICC) and coefficient of variation (CV), respectively. An analysis of variance examined differences between the GPS measurement and five laps of 200 m at 15 km/h, and t -test examined differences between the GPS measurement and 20 m shuttle run endurance test. The difference between the GPS measurement and 200 m distance ranged from -0.13 ± 3.94 m (95% CI -3.42; 3.17) in the first lap to 2.13 ± 2.64 m (95% CI -0.08; 4.33) in the fifth lap. A good intra-unit reliability was observed in 200 m (ICC = 0.833, 95% CI 0.535; 0.962). Inter-unit CV ranged from 1.31% (fifth lap) to 2.20% (third lap). The difference between the GPS measurement and 20 m shuttle run endurance test ranged from 0.33 ± 4.16 m (95% CI -10.01; 10.68) in 11.5 km/h to 9.00 ± 5.30 m (95% CI 6.44; 11.56) in 8.0 km/h. A moderate intra-unit reliability was shown in the second and third stage of the 20 m shuttle run endurance test (ICC = 0.718, 95% CI 0.222;0.898) and good reliability in the fifth, sixth, seventh and eighth (ICC = 0.831, 95% CI -0.229;0.996). Inter-unit CV ranged from 2.08% (11.5 km/h) to 3.92% (8.5 km/h). Based on these findings, it was concluded that the 10 Hz Johan system offers an affordable valid and reliable tool for coaches and fitness trainers to monitor training and performance.

Principal reference section for part of the Eocene Ghazij Formation, Moghal Mine area, Mach coal field, Balochistan, Pakistan

The information presented on this sheet was collected as part of a joint U.S. Geological Survey-Geological Survey of Pakistan program sponsored by the U.S. Agency for International Development. As a project within this program, the coal-bearing Ghazij Formation (Eocene) was investigated in the northeastern part of Balochistan cast and south of the provincial capital of Quetta. Strata exposed in this area range in age from Permian to Holocene and crop out as a belt of folded and thrusted rocks that form a southeast-facing orocline. In this region of Pakistan, the Ghazij can usually be divided into three parts. The lower part is the thickest (probably more than 1,000 m) and consists of gray-weathering calcareous mudrock (shale, mudstone, and impure claystone) and a few tabular bodies of fine-to medium-grained calcareous sandstone. The middle part (27-300 m) consists of gray-weathering calcareous mudrock and tabular to lenticular bodies of fine-to medium-grained calcareous sandstone; beds of carbonaceous shale and coal are common. The upper part (as thick as 533 m) contains reddish-weathering calcareous mudrock that contains scattered lenticular bodies of fine- to medium-grained calcareous sandstone. Fossil plant debris is common in mudrock of the lower and middle parts of the Ghazij, and bivalves and gastropods are common in the middle part; the upper part of the Ghazij is usually unfossiliferous. This three-fold division of the Ghazij is less distinct in the Johan area. Here, the upper part of the formation is clearly identifiable, but rocks below it are poorly exposed and assigning a stratigraphic level that separates the middle and lower parts of the formation is problematic. Below the upper part of the formation is a thick sequence of greenish-gray calcareous mudrock that contains locally abundant plant debris and isolated bodies of brown-weathering sandstone. Rare carbonaceous shale and even rarer coal are present in the upper part of this sequence, and this

This project is a subtask of a multi-center project to advance the state-of-the-art by developing NDE techniques that are capable of evaluating stress rupture (SR) degradation in Kevlar/epoxy (K/Ep) composite overwrapped pressure vessels (COPVs), and damage progression in carbon/epoxy (C/Ep) COPVs. In this subtask, acoustic emission (AE) data acquired during intermittent load hold tensile testing of K/Ep and C/Ep composite tow materials-of-construction used in COPV fabrication were analyzed to monitor progressive damage during the approach to tensile failure. Insight into the progressive damage of composite tow was gained by monitoring AE event rate, energy, source location, and frequency. Source location based on arrival time data was used to discern between significant AE attributable to microstructural damage and spurious AE attributable to background and grip noise. One of the significant findings was the observation of increasing violation of the Kaiser effect (Felicity ratio < 1.0) with damage accumulation.

Seismic performance evaluation of an historical concrete deck arch bridge using survey and drawing of the damages, in situ tests, dynamic identification and pushover analysis

The paper describes the performance evaluation of a retrofit historical multi-span (RC) deck arch bridge analyzed with in situ tests, dynamic identification and FEM analysis. The peculiarity of this case study lies in the structural typology of "San Felice" bridge, an historical concrete arch bridge built in the early 20th century, a quite uncommon feature in Italy. The preservation and retrofit of historic cultural heritage and infrastructures has been carefully analyzed in the international codes governing seismic response. A complete survey of the bridge was carried out prior to sketching a drawing of the existing bridge. Subsequently, the study consists in four steps: material investigation and dynamic vibration tests, FEM analysis and calibration, retrofit assessment, pushover analysis. The aim is to define an innovative approach to calibrate the FEM analysis through modern experimental investigations capable of taking structural deterioration into account, and to offer an appropriate and cost-effective retrofitting strategy.

'Il Sonnambulo' by Michele Carafa: A Forgotten Romantic Opera with Sleepwalking.

Romantic operas provide a useful tool for historians to understand the perception of some medical disorders that existed during the nineteenth century. Somnambulism was still a mysterious condition during this time, since its pathogenesis was unknown. Hence, it comes as no surprise that somnambulism features in a number of operas, the best known of which are Verdi's 'Macbeth' and Bellini's 'La Sonnambula', both the subject of recent scholarship. Here we examine a more obscure opera in which sleepwalking is depicted. Dating from 1824, 'Il Sonnambulo' by the Italian composer Michele Carafa is based on a libretto by Felice Romani. Although it shares some features with the Verdi and Bellini operas, it also presents original elements. Our analysis of this forgotten opera supports the contention that studying operas can shed light on medical theories and practices, and on how ideas about mind and body disorders were transmitted to the laity in times past. © 2016 S.

For centuries, difficulties have occurred in determining unresolved paternities. In addition to the modern standard methods, such as the examination of DNA or serological proof, expert opinion on fertility once played an important role. The andrological difference between incapability to fertilise and the inability to participate in sexual intercourse was also distinguished historically. Of special significance was the discovery of spermatozoa by the medical student Johan Ham in 1677 and their further investigation by Antoni van Leeuwenhoek.Recently, modern DNA methods have also been applied for historical investigations. Illustrious examples are the DNA analysis in the case of Kaspar Hauser of Ansbach and the dispute about Thomas Jefferson, President of the U.S., fathering a child by one of his slaves. In this discourse, a medicinal-forensic review of the development of expert opinion, illustrated with historical case studies, is given.

During the last century, Johan Hjort's work has lead to signicant advances in explaining anomalous year-classes within sheries science. However, distinguishing between the competing mechanisms of year-class regulation (e.g., food conditions, predation, transport) has proved challenging. We use blue whiting (Micromesistius poutassou) in the North-east Atlantic Ocean as a case study, which, during the late 1990s and early 2000s, generated year-classes up to nearly an order of magnitude higher than those seen before or after. There presently exists no models that can quantify past variations in recruitment for this stock. Using modern stock-statistical and observational tools, we catalog a range of environmentally-driven hypotheses relevant for recruitment of blue whiting, including physical and biogeographic conditions, phenology, parental effects and predation. We have run the analyses to test some hypotheses and results will be presented at the session.

Linnaeans outdoors: the transformative role of studying nature 'on the move' and outside.

Hodacs, Hanna

2011-06-01

Travelling is an activity closely associated with Carolus Linnaeus (1707-1778) and his circle of students. This article discusses the transformative role of studying nature outdoors (turning novices into naturalists) in eighteenth-century Sweden, using the little-known journeys of Carl Bäck (1760-1776), Sven Anders Hedin (1750-1821) and Johan Lindwall (1743-1796) as examples. On these journeys, through different parts of Sweden in the 1770s, the outdoors was used, simultaneously, as both a classroom and a space for exploration. The article argues that this multifunctional use of the landscape (common within the Linnaean tradition) encouraged a democratization of the consumption of scientific knowledge and also, to some degree, of its production. More generally, the study also addresses issues of how and why science and scientists travel by discussing how botanical knowledge was reproduced and extended 'on the move', and what got senior and junior students moving.

Playing With Antidepressants: Perspectives From Indian Australians and Anglo-Australians Living With Depression.

PubMed

Brijnath, Bianca; Antoniades, Josefine

2017-11-01

Patient perspectives were explored on the meaning and experience of antidepressant use by applying Johan Huizinga's theory of play to interviews from Indian Australians and Anglo-Australians diagnosed with depression. Through the analysis, the centrality of Huizinga's "magic circle" emerged, that is, defining the boundaries within which one could safely play. Consumption of antidepressants involved learning, breaking, and modulating rules of the game of adherence, then forging a new "magic circle." In these games, there were playful elements including experimentation, improvisation, absorption, and experiential learning. This application of Huizinga's theory in relation to antidepressant use is a novel approach in the literature on medication non/adherence. This application not only opens a new theoretical line of inquiry but also shows that antidepressant non/adherence is not a static practice but dynamic and changing, revealing critical insights around participant's agency, capabilities, desires, and notions of selfhood with regard to managing their depression and conceptualizing their recovery.

Bingo! Holy play in experience-oriented society.

What place is there for holy play in experience-oriented society? Is it possible and useful to make analytic distinctions between the liturgical quality of events? I explored these questions by doing research on the boundaries between the religious field and the field of leisure. Fifty site visits to public events in the Netherlands (2006-2014) resulted in a collection of ethnographic data. I used the concept of play as introduced by the Dutch historian Johan Huizinga and the tools of ritual studies to explore whether these could help to produce an account of the liturgical quality of ritualized meetings. Holy play might be found in unexpected places, such as in a bingo hall. Huizinga's broad diagnosis of modernity may be outdated, but the tools he introduced remain useful to distinguish the elements that constitute late-modern meetings as more or less playful - even when this involves combinations that seem contradictory from Huizinga's own point of view.

Use of Modal Acoustic Emission to Monitor Damage Progression in Carbon Fiber/Epoxy Tows and Implications for Composite Structures

Waller, Jess M.; Saulsberry, Regor L.; Nichols, Charles T.; Wentzel, Daniel J.

2010-01-01

This slide presentation reviews the use of Modal Acoustic Emission to monitor damage progression to carbon fiber/epoxy tows. There is a risk for catastrophic failure of composite overwrapped pressure vessels (COPVs) due to burst-before-leak (BBL) stress rupture (SR) failure of carbon-epoxy (C/Ep) COPVs. A lack of quantitative nondestructive evaluation (NDE) is causing problems in current and future spacecraft designs. It is therefore important to develop and demonstrate critical NDE that can be implemented during stages of the design process since the observed rupture can occur with little of no advanced warning. Therefore a program was required to develop quantitative acoustic emission (AE) procedures specific to C/Ep overwraps, but which also have utility for monitoring damage accumulation in composite structure in general, and to lay the groundwork for establishing critical thresholds for accumulated damage in composite structures, such as COPVs, so that precautionary or preemptive engineering steps can be implemented to minimize of obviate the risk of catastrophic failure. A computed Felicity Ratio (FR) coupled with fast Fourier Transform (FFT) frequency analysis shows promise as an analytical pass/fail criterion. The FR analysis and waveform and FFT analysis are reviewed

Spatial variation of salt-marsh organic and inorganic deposition and organic carbon accumulation: Inferences from the Venice lagoon, Italy

Salt marshes are ubiquitous features of the tidal landscape governed by mutual feedbacks among processes of physical and biological nature. Improving our understanding of these feedbacks and of their effects on tidal geomorphological and ecological dynamics is a critical step to address issues related to salt-marsh conservation and response to changes in the environmental forcing. In particular, the spatial variation of organic and inorganic soil production processes at the marsh scale, a key piece of information to understand marsh responses to a changing climate, remains virtually unexplored. In order to characterize the relative importance of organic vs. inorganic deposition as a function of space, we collected 33 shallow soil sediment samples along three transects in the San Felice and Rigà salt marshes located in the Venice lagoon, Italy. The amount of organic matter in each sample was evaluated using Loss On Ignition (LOI), a hydrogen peroxide (H2O2) treatment, and a sodium hypochlorite (NaClO) treatment following the H2O2 treatment. The grain size distribution of the inorganic fraction was determined using laser diffraction techniques. Our study marshes exhibit a weakly concave-up profile, with maximum elevations and coarser inorganic grains along their edges. The amount of organic and inorganic matter content in the samples varies with the distance from the marsh edge and is very sensitive to the specific analysis method adopted. The use of a H2O2+NaClO treatment yields an organic matter density value which is more than double the value obtained from LOI. Overall, inorganic contributions to soil formation are greatest near the marsh edges, whereas organic soil production is the main contributor to soil accretion in the inner marsh. We interpret this pattern by considering that while plant biomass productivity is generally lower in the inner part of the marsh, organic soil decomposition rates are highest in the better aerated edge soils. Hence the higher

Moral differences in deep continuous palliative sedation and euthanasia.

In palliative care there is much debate about which end of life treatment strategies are legitimate and which are not. Some writers argue that there is an important moral dividing-line between palliative sedation and euthanasia, making the first acceptable and the latter not. We have questioned this. In a recent article, Lars Johan Materstvedt has argued that we are wrong on two accounts: first, that we fail to account properly for the moral difference between continuous deep palliative sedation at the end of life and euthanasia, and, second, that we fail to account properly for the difference between permanent loss of consciousness and death. Regarding the first objection, we argue that Materstvedt misses the point: we agree that there is a difference in terms of intentions between continuous deep palliative sedation and euthanasia, but we question whether this conceptual difference makes up for a moral difference. Materstvedt fails to show that it does. Regarding the second objection, we argue that if nothing else is at stake than the value of the patient's life, permanent unconsciousness and death are morally indifferent.

Onboard image processing systems for a hyperspectral sensor have been developed in order to maximize image data transmission efficiency for large volume and high speed data downlink capacity. Since more than 100 channels are required for hyperspectral sensors on Earth observation satellites, fast and small-footprint lossless image compression capability is essential for reducing the size and weight of a sensor system. A fast lossless image compression algorithm has been developed, and is implemented in the onboard correction circuitry of sensitivity and linearity of Complementary Metal Oxide Semiconductor (CMOS) sensors in order to maximize the compression ratio. The employed image compression method is based on Fast, Efficient, Lossless Image compression System (FELICS), which is a hierarchical predictive coding method with resolution scaling. To improve FELICS’s performance of image decorrelation and entropy coding, we apply a two-dimensional interpolation prediction and adaptive Golomb-Rice coding. It supports progressive decompression using resolution scaling while still maintaining superior performance measured as speed and complexity. Coding efficiency and compression speed enlarge the effective capacity of signal transmission channels, which lead to reducing onboard hardware by multiplexing sensor signals into a reduced number of compression circuits. The circuitry is embedded into the data formatter of the sensor system without adding size, weight, power consumption, and fabrication cost. PMID:26404281

Early Damage Detection in Composites during Fabrication and Mechanical Testing.

Fully integrated monitoring systems have shown promise in improving confidence in composite materials while reducing lifecycle costs. A distributed optical fibre sensor is embedded in a fibre reinforced composite laminate, to give three sensing regions at different levels through-the-thickness of the plate. This study follows the resin infusion process during fabrication of the composite, monitoring the development of strain in-situ and in real time, and to gain better understanding of the resin rheology during curing. Piezoelectric wafer active sensors and electrical strain gauges are bonded to the plate after fabrication. This is followed by progressive loading/unloading cycles of mechanical four point bending. The strain values obtained from the optical fibre are in good agreement with strain data collected by surface mounted strain gauges, while the sensing regions clearly indicate the development of compressive, neutral, and tensile strain. Acoustic emission event detection suggests the formation of matrix (resin) cracks, with measured damage event amplitudes in agreement with values reported in published literature on the subject. The Felicity ratio for each subsequent loading cycle is calculated to track the progression of damage in the material. The methodology developed here can be used to follow the full life cycle of a composite structure, from manufacture to end-of-life.

Courting the future: cancer and genetics in Cuba.

PubMed

2014-01-01

Describing this double issue of MEDICC Review could be an exercise for a first-year philosophy course in logic. It's not about "cancer and genetics" in Cuba. It's about cancer in Cuba and about genetics in Cuba, not about exploring relationships between them. Nevertheless, while the marriage of the two themes was fortuitous, in that the two had long been scheduled for the journal in 2014, there is a certain felicity to their sharing an issue. To date, the outstanding accomplishments of genetics have been most helpful for conditions occurring at the beginning of life and cancer is largely (though not exclusively) a disease related to aging. But the two are intrinsically connected: Although only a few of the more than 100 different diseases grouped under the term cancer are known to be hereditary, every cancer begins with a mutation in one or more genes, whether the mutation is inherited, due to an exposure, or is simply a random error in the millions of cell divisions that are part and parcel of cellular reproduction. Our cover image, a stained-glass window by Cuban artist Rosa María de la Terga at Cuba's National Medical Genetics Center, illustrates the elegance of the DNA molecule, the intricate key to life.

Acoustic emission during quench training of superconducting accelerator magnets

NASA Astrophysics Data System (ADS)

Marchevsky, M.; Sabbi, G.; Bajas, H.; Gourlay, S.

2015-07-01

Acoustic emission (AE) sensing is a viable tool for superconducting magnet diagnostics. Using in-house developed cryogenic amplified piezoelectric sensors, we conducted AE studies during quench training of the US LARP's high-field quadrupole HQ02 and the LBNL's high-field dipole HD3. For both magnets, AE bursts were observed, with spike amplitude and frequency increasing toward the quench current during current up-ramps. In the HQ02, the AE onset upon current ramping is distinct and exhibits a clear memory of the previously-reached quench current (Kaiser effect). On the other hand, in the HD3 magnet the AE amplitude begins to increase well before the previously-reached quench current (felicity effect), suggesting an ongoing progressive mechanical motion in the coils. A clear difference in the AE signature exists between the untrained and trained mechanical states in HD3. Time intervals between the AE signals detected at the opposite ends of HD3 coils were processed using a combination of narrow-band pass filtering; threshold crossing and correlation algorithms, and the spatial distributions of AE sources and the mechanical energy release were calculated. Both distributions appear to be consistent with the quench location distribution. Energy statistics of the AE spikes exhibits a power-law scaling typical for the self-organized critical state.

Morphology of AGN in the Central Kiloparsec

NASA Astrophysics Data System (ADS)

Martini, Paul

Hubble Space Telescope observations of the central kiloparsec of AGN have revealed a wealth of structure, particularly nuclear bars and spirals, that are distinct from analogous features in the disks of spiral galaxies. WFPC2 and NICMOS images of a large sample of AGN observed at high spatial resolution make it possible to quantify the frequency and detailed properties of these structures. Nearly all AGN have nuclear spiral dust lanes in the central kiloparsec, while only a small minority contain nuclear bars. If these nuclear dust spirals trace shocks in the circumnuclear, gaseous disks, they may dissipate sufficient angular momentum to fuel the active nucleus. I would like to thank my collaborators in this project---Rick Pogge, John Mulchaey, and Mike Regan---for allowing me to present this work in advance of publication, as well as Johan Knapen for organizing such an interesting meeting.

Frederik Kaiser (1808-1872) and the Modernisation of Dutch Astronomy

NASA Astrophysics Data System (ADS)

van der Heijden, Petra

Frederik Kaiser was the director of Leiden Observatory from 1837 until his death in 1872. Educated by his German-born uncle Johan Frederik Keyser (1766-1823), who was a proficient amateur astronomer, Kaiser proved to be a real observational talent. Despite the poor conditions in which he worked, his observations soon rivalled with the best in the world. Kaiser's contributions to astronomical practice include the foundation of a new, completely up-to-date observatory building in Leiden, and the introduction of statistics and precision measurements in daily practice at the observatory. Moreover he was the author of several bestselling books on popular astronomy. Kaiser had an extensive correspondence with colleagues all over Europe, mostly in Germany. Correpondents include Airy, Argelander, Von Auwers, Bessel, Encke, John Herschel, LeVerrier, Von Littrow, Schumacher, Otto W. Struve, as well as several geodesists and instrument makers. Preliminary research indicates that Frederik Kaiser played a crucial role in the revival of Dutch astronomy in the second half of the 19th century. This project aims at analysing and explaining Kaiser's activities in science, institutionalisation and popularisation, in the context of national and international developments in 19th-century astronomy and scientific culture.

General relativistic satellite astrometry. II. Modeling parallax and proper motion

NASA Astrophysics Data System (ADS)

de Felice, F.; Bucciarelli, B.; Lattanzi, M. G.; Vecchiato, A.

2001-07-01

The non-perturbative general relativistic approach to global astrometry introduced by de Felice et al. (\\cite{defetal}) is here extended to account for the star motions on the Schwarzschild celestial sphere. A new expression of the observables, i.e. angular distances among stars, is provided, which takes into account the effects of parallax and proper motions. This dynamical model is then tested on an end-to-end simulation of the global astrometry mission GAIA. The results confirm the findings of our earlier work, which applied to the case of a static (angular coordinates only) sphere. In particular, measurements of large arcs among stars (each measurement good to ~ 100 mu arcsec, as expected for V ~ 17 mag stars) repeated over an observing period comparable to the mission lifetime foreseen for GAIA, can be modeled to yield estimates of positions, parallaxes, and annual proper motions good to ~ 15 mu arcsec. This second round of experiments confirms, within the limitations of the simulation and the assumptions of the current relativistic model, that the space-born global astrometry initiated with Hipparcos can be pushed down to the 10-5 arcsec accuracy level proposed with the GAIA mission. Finally, the simplified case we have solved can be used as reference for testing the limiting behavior of more realistic models as they become available.

Is atherosclerosis fundamental to human aging? Lessons from ancient mummies.

Case reports from Johan Czermak, Marc Ruffer, and others a century or more ago demonstrated ancient Egyptians had atherosclerosis three millennia ago. The Horus study team extended their findings, demonstrating that atherosclerosis was prevalent among 76 ancient Egyptian mummies and among 61 mummies from each of the ancient cultures of Peru, the American Southwest, and the Aleutian Islands. These findings challenge the assumption that atherosclerosis is a modern disease caused by present day risk factors. An extensive autopsy of an ancient Egyptian teenage male weaver named Nakht found that he was infected with four parasites: Schistosoma haematobium, Taenia species, Trichinella spiralis, and Plasmodium falciparum. Modern day patients with chronic inflammatory disease such as rheumatoid arthritis, systemic lupus erythematosus, and human immunodeficiency virus experience premature atherosclerosis. Could the burden of chronic inflammatory disease have been a risk factor for atherosclerosis in these ancient cultures? The prevalence of atherosclerosis in four diverse ancient cultures is consistent with atherosclerosis being fundamental to aging. The impact of risk factors in modern times, and potentially in ancient times, suggests a strong gene-environmental interplay: human genes provide a vulnerability to atherosclerosis, the environment determines when and if atherosclerosis becomes manifest clinically.

To compare the efficacy of the most familiar clinical prediction rules in combination with D-dimer testing to rule out a diagnosis of deep vein thrombosis (DVT) in a hospital emergency department. Retrospective cross-sectional analysis of the case records of all patients attending a hospital emergency department with suspected lower-limb DVT between 1998 and 2002. Ten clinical prediction scores were calculated and D-dimer levels were available for all patients. The gold standard was ultrasound diagnosis of DVT by an independent radiologist who was blinded to clinical records. For each prediction rule, we analyzed the effectiveness of the prediction strategy defined by "low clinical probability and negative D-dimer level" against the ultrasound diagnosis. A total of 861 case records were reviewed and 577 cases were selected; the mean (SD) age was 66.7 (14.2) years. DVT was diagnosed in 145 patients (25.1%). Only the Wells clinical prediction rule and 4 other models had a false negative rate under 2%. The Wells criteria and the score published by Johanning and colleagues identified higher percentages of cases (15.6% and 11.6%, respectively). This study shows that several clinical prediction rules can be safely used in the emergency department, although none of them have proven more effective than the Wells criteria.

The present work explores the structures of species formed by dehydrogenation of methane (CH4) and perdeuterated methane (CD4) by the 5d transition metal cation osmium (Os+). Using infrared multiple photon dissociation (IRMPD) action spectroscopy and density functional theory (DFT), the structures of the [Os,C,2H]+ and [Os,C,2D]+ products are explored. This study complements previous work on the related species formed by dehydrogenation of methane by four other 5d transition metal cations (M+ = Ta+, W+, Ir+, and Pt+). Osmium cations are formed in a laser ablation source, react with methane pulsed into a reaction channel downstream, and the resulting products spectroscopically characterized through photofragmentation using the Free-Electron Laser for IntraCavity Experiments (FELICE) in the 300-1800 cm-1 range. Photofragmentation was monitored by the loss of H2/D2. Comparison of the experimental spectra and DFT calculated spectra leads to identification of the ground state carbyne hydride, HOsCH+ (2A') as the species formed, as previously postulated theoretically. Further, a full description of the systematic spectroscopic shifts observed for deuterium labeling of these complexes, some of the smallest systems to be studied using IRMPD action spectroscopy, is achieved. A full rotational contour analysis explains the observed linewidths as well as the observation of doublet structures in several bands, consistent with previous observations for HIrCH+ (2A').

The history of the investigations about of the so-called irritability of animal tissues showed by English physician Francis Glisson in the 17th century, is summarized. During the 18th century, reliable studies on the bioelectric properties of these tissues began, due to the Swiss scientist Albrecht von Haller and continuated by the Italian naturalist Felice Fontana. In the second half of this century, multiple controversies of the partisans of the animal electricity against the partisans of the contact electricity took place. The Danish scientist Oersted in 1820 proved the close relation of magnetism to electricity, which led to construction of electrometers. These instruments allowed to register and measure record of the electric current. On this way, at middle 21st century, the true animal electricity was identified as the injury current. Later it was possible to record the electric current, risen in the myocardium, out the thorax first by means of the Lippmann' capillary electrometer and later thanks to the Einthoven's string galvanometer at the beginning of the 20th century. So the modern electro-vectorcardiography took off, due to English Thomas Lewis, the North-American Frank N. Wilson and the Mexican Demetrio Sodi Pallares. The last one allowed to rationalize the electro-vectorcardiographic exploration on experimental bases. Copyright © 2013 Instituto Nacional de Cardiología Ignacio Chávez.

Recent glacial events in the Norwegian North Sea - implications towards a better understanding of charging/leakage of oil fields and its impact oil exploration

NASA Astrophysics Data System (ADS)

Stoddart, Daniel

2014-05-01

Recent drilling and appraisal on the Southern Utsira High, Norwegian North Sea, has proved several large oil/gas discoveries, including the giant Johan Sverdrup, Edvard Grieg, Draupne, Ragnarrock and Apollo oil fields, making this a prolific petroleum area. The Southern Utsira High contains a variety of hydrocarbon density fluids found at several stratigraphic levels illustrating the compartmentalized nature of accumulations and charge history. The Southern Utsira High has been in a position to receive an oil/gas charge for a considerable period of time, with the basin towards the west most likely generating petroleum from early Eocene (50M Mabp) to its maximum present day burial depth. However, reservoir temperatures on the Southern Utsira High are just above the threshold for biodegradation (80°C). The Southern Utsira High oils are non-biodegraded suggesting that the majority of the oil charged relatively late - ca.3 million years ago to present day. The effects of the glaciation on the filling history of the Southern Utsira High are currently being assessed. It is clear that several erosional surfaces in the Pliocene can be identified, as well as glacial channels and moraine deposits, indicating that significant deposition and erosion occurred in the last five million years. Importantly, the effects of glacial rebound mean that the Southern Utsira High more than likely underwent tilting and possible leakage, not just once, but several times in the last 1 million years. The effects of tilting/leakage of geological areas on oil migration have been recognized by several authors. However, the detailed integration of geological mapping and geochemical evidence has not previously been published. The implications of a detailed assessment of tilting of a ''high' through time are; 1) opening up areas where oil migration is thought to be high risk or impossible; 2) identify possible paleo-oil columns aiding the de-risking of discovery appraisal strategies.

How Alexander von Humboldt's life story can inspire innovative soil research in developing countries

The pioneering vision of Alexander von Humboldt of science and society of the early 1800s is still highly relevant today. His open mind and urge to make many measurements characterizing the interconnected web of life are crucial ingredients as we now face the worldwide challenge of the UN Sustainable Development Goals. Case studies in the Philippines, Vietnam, Kenya, Niger, and Costa Rica demonstrate, in Alexander's spirit, interaction with stakeholders and attention to unique local conditions, applying modern measurement and modeling methods and allowing inter- and transdisciplinary research approaches. But relations between science and society are increasingly problematic, partly as a result of the information revolution and post-truth, fact-free thinking. Overly regulated and financially restricted scientific communities in so-called developed countries may stifle intellectual creativity. Researchers in developing countries are urged to leapfrog these problems in the spirit of Alexander von Humboldt as they further develop their scientific communities. Six suggestions to the science community are made with particular attention to soil science.

This article is a review of the foundation (in 1838) and later developments of the Helsinki (Finland) magnetic and meteorological observatory, today the Finnish Meteorological Institute (FMI). The main focus of the study is in the early history of the FMI up to the beginning of the 20th century. The first director of the observatory was Physics Professor Johan Jakob Nervander (1805-1848). He was a famous person of the Finnish scientific, academic and cultural community in the early decades of the 19th century. Finland was an autonomously part of the Russian Empire from 1809 to 1917, but the observatory remained organizationally under the University of Helsinki, independent of Russian scientific institutions, and funded by the Finnish Government. Throughout the late-19th century the Meteorological Institute was responsible of nationwide meteorological, hydrological and marine observations and research. The observatory was transferred to the Finnish Society of Sciences and Letters under the name the Central Meteorological Institute in 1881. The focus of the work carried out in the Institute was changed gradually towards meteorology. Magnetic measurements were still continued but in a lower level of importance. The culmination of Finnish geophysical achievements in the 19th century was the participation to the International Polar Year programme in 1882-1883 by setting up a full-scale meteorological and magnetic observatory in Sodankylä, Lapland.

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

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

Exploring the safe and just operating space in an inhomogeneous world

The Anthropocene has become reality during the 20th century, implying that our species is pressuring the Earth's ecosystems on a global scale. In the meantime, the challenge of eradicating poverty has not yet ceased to exist. Effectively dealing with these issues requires us to better understand the driving forces, feedback loops and tipping elements in the whole Earth system, constituted by natural and social components. To take a step forward in this direction, we refine an existing conceptual coevolutionary model of social and ecological domains (COPAN:EXPLOIT) by introducing inhomogeneities in the properties of local renewable resource stocks that are abstracted from real-world data. We then propose an analytical framework, 'the safe and just space'- plot, which aligns with the current debate on how to simultaneously stay within planetary boundaries (Rockström et al., 2009) and at the same time ensure that social foundations are met (Raworth, 2012). This plot presents a practical tool for jointly studying global socio-ecological models as well as real-world observations. First results from comparing the model outputs with real-world data indicate that the current state of the world is neither particularly safe nor particularly just.

["To suffer an ordeal": Some Swedish physicians' struggle during the nineteenth century against unhygienic female dress].

Tight-lacing of the female body has been practised at various periods in the history of costume. During the romantic age of the nineteenth century the ideal women had to be pale, weak and often pathologically thin. She was supposed to be of a humble disposition and subservient to her husband (according to the doctrine of subordination). Women laced themselves so tightly that their bodies became deformed, with physical injuries and damage to the internal organs as a consequence. Competition for suitable husbands was keen, since marriage was the only honourable way for a woman to ensure that she would be provided for. It was also in the nineteenth century that doctors were beginning to fight against endemic disease and to argue for a more hygienic way of life. They maintained that women were slaves to fashion and that they dressed in an unhygienic way. Above all, they campaigned against the use of tight-laced corsets. Swedish doctors, such as Anton Nyström, Truls Johan Harterlius and Karolina Widerström headed the fight against the use of laced corsetes, on both medical and social grounds. An improved and "informed" costume was introduced which was meant to allow women greater freedom of movement, thus enabling them to live a more natural life. It was, however, not until 1910 that the tightly-laced corset was abandoned. The conclusion of this is that the history of costume is "the history of absurd follies".

To study whether Johan Sebastian Bach music has a lowering effect on resting energy expenditure (REE) similar to that of Wolfgang Amadeus Mozart music. Prospective, randomized clinical trial with cross-over in 12 healthy, appropriate weights for gestational age (GA), gavage fed, metabolically stable, preterm infants. Infants were randomized to a 30-min period of either Mozart or Bach music or no music over 3 consecutive days. REE was measured every minute by indirect calorimetry. Three REE measurements were performed in each of 12 infants at age 20±15.8 days. Mean GA was 30.17±2.44 weeks and mean birthweight was 1246±239 g. REE was similar during the first 10-min of all three randomization periods. During the next 10-min period, infants exposed to music by Mozart had a trend toward lower REE than when not exposed to music. This trend became significant during the third 10-min period. In contrast, music by Bach or no music did not affect significantly REE during the whole study. On average, the effect size of Mozart music upon REE was a reduction of 7.7% from baseline. Mozart music significantly lowers REE in preterm infants, whereas Bach music has no similar effect. We speculate that 'Mozart effect' must be taken into account when incorporating music in the therapy of preterm infants, as not all types of music may have similar effects upon REE and growth.

Unravelling the Mysteries of Slip Histories, Validating Cosmogenic 36Cl Derived Slip Rates on Normal Faults

The cosmogenic isotope chlorine-36 (36Cl) is increasingly used as a tool to investigate normal fault slip rates over the last 10-20 thousand years. These slip histories are being used to address complex questions, including investigating slip clustering and understanding local and large scale fault interaction. Measurements are time consuming and expensive, and as a result there has been little work done validating these 36Cl derived slip histories. This study aims to investigate if the results are repeatable and therefore reliable estimates of how normal faults have been moving in the past. Our approach is to test if slip histories derived from 36Cl are the same when measured at different points along the same fault. As normal fault planes are progressively exhumed from the surface they accumulate 36Cl. Modelling these 36Cl concentrations allows estimation of a slip history. In a previous study, samples were collected from four sites on the Magnola fault in the Italian Apennines. Remodelling of the 36Cl data using a Bayesian approach shows that the sites produced disparate slip histories, which we interpret as being due to variable site geomorphology. In this study, multiple sites have been sampled along the Campo Felice fault in the central Italian Apennines. Initial results show strong agreement between the sites we have processed so far and a previous study. This indicates that if sample sites are selected taking the geomorphology into account, then 36Cl derived slip histories will be highly similar when sampled at any point along the fault. Therefore our study suggests that 36Cl derived slip histories are a consistent record of fault activity in the past.

Prediction of plasma-facing ICRH antenna behavior via a Finite-Element solution of coupled Integral Equations

The demand for a predictive tool to help designing ICRH antennas for fusion experiments has driven the development of codes like ICANT, RANT3D, and the early developments and further upgrades of TOPICA code. Currently, TOPICA handles the actual geometry of ICRH antennas (with their housing, etc.) as well as a realistic plasma model, including density and temperature profiles and FLR effects. Both goals have been attained by formally splitting the problem into two parts: the vacuum region around the antenna, and the plasma region inside the toroidal chamber. Field continuity and boundary conditions allow writing a set of coupled integral equations for the unknown equivalent (current) sources; finite elements are used on a triangular-cell mesh and a linear system is obtained on application of the weighted-residual solution scheme. In the vacuum region calculations are done in the spatial domain, whereas in the plasma region a spectral (wavenumber) representation of fields and currents is adopted, thus allowing a description of the plasma by a surface impedance matrix. Thanks to this approach, any plasma model can be used in principle, and at present Brambilla's FELICE code has been employed. The natural outputs of TOPICA are the induced currents on the conductors and the electric field in front of the plasma, whence the antenna circuit parameters (impedance/scattering matrices), the radiated power and the fields (at locations other than the chamber aperture) are then obtained. An accurate model of the feeding coaxial lines is also included. This paper is precisely devoted to the description of TOPICA, whereas examples of results for real-life antennas are reported in a companion paper [1] in this proceedings.

Nonalcoholic fatty liver disease (NAFLD) is widespread in adults and children. Early exposure to maternal obesity or Western-style diet (WD) increases steatosis and oxidative stress in fetal liver and is associated with lifetime disease risk in the offspring. Pyrroloquinoline quinone (PQQ) is a natural antioxidant found in soil, enriched in human breast milk, and essential for development in mammals. We investigated whether a supplemental dose of PQQ, provided prenatally in a mouse model of diet-induced obesity during pregnancy, could protect obese offspring from progression of NAFLD. PQQ treatment given pre- and postnatally in WD-fed offspring had no effect on weight gain but increased metabolic flexibility while reducing body fat and liver lipids, compared with untreated obese offspring. Indices of NAFLD, including hepatic ceramide levels, oxidative stress, and expression of proinflammatory genes ( Nos2 , Nlrp3 , Il6 , and Ptgs2 ), were decreased in WD PQQ-fed mice, concomitant with increased expression of fatty acid oxidation genes and decreased Pparg expression. Notably, these changes persisted even after PQQ withdrawal at weaning. Our results suggest that supplementation with PQQ, particularly during pregnancy and lactation, protects offspring from WD-induced developmental programming of hepatic lipotoxicity and may help slow the advancing epidemic of NAFLD in the next generation.-Jonscher, K.

Women as a business imperative.

Schwartz, F N

1992-01-01

In 1989, Felice N. Schwartz's HBR article "Management Women and the New Facts of Life" generated a huge debate over the rules established by corporations in their handling of women executives. Now in "Women as a Business Imperative," Schwartz follows up with practical insights about the costs companies incur in passing over qualified businesswomen. In the form of a memo to a fictional CEO, Schwartz describes how the atmosphere within most companies is corrosive to women and must change. Preconceptions harbored by male senior managers about women are so deeply ingrained that many men are not even aware of them. Yet senior managers must help women advance. Those companies that accept their responsibility to make radical change--both in women's treatment and in family support--can improve their bottom lines enormously. Treating women as a business imperative is the equivalent of creating a unique R&D product for which there is great demand. Most companies ignore child care and other family concerns. Many companies hire women to ensure mere adequacy and avoid litigation. Women's ambitions and energies are stifled by such businesses at the same time that women have demonstrated their competence and potential in the best business schools. High turnover results. However, the restraints that now hold women back can be loosened easily. CEOs and other senior managers must support their female employees by (1) acknowledging the fundamental difference between women and men--the biological fact of maternity; (2) allowing flexibility for women and men who need it; (3) providing training that takes advantage of women's leadership potential; and (4) eliminating the corrosive atmosphere and the barriers that exist for women in the workplace.

Substrate binding stoichiometry and kinetics of the norepinephrine transporter.

Schwartz, Joel W; Novarino, Gaia; Piston, David W; DeFelice, Louis J

2005-05-13

The human norepinephrine (NE) transporter (hNET) attenuates neuronal signaling by rapid NE clearance from the synaptic cleft, and NET is a target for cocaine and amphetamines as well as therapeutics for depression, obsessive-compulsive disorder, and post-traumatic stress disorder. In spite of its central importance in the nervous system, little is known about how NET substrates, such as NE, 1-methyl-4-tetrahydropyridinium (MPP+), or amphetamine, interact with NET at the molecular level. Nor do we understand the mechanisms behind the transport rate. Previously we introduced a fluorescent substrate similar to MPP+, which allowed separate and simultaneous binding and transport measurement (Schwartz, J. W., Blakely, R. D., and DeFelice, L. J. (2003) J. Biol. Chem. 278, 9768-9777). Here we use this substrate, 4-(4-(dimethylamino)styrl)-N-methyl-pyridinium (ASP+), in combination with green fluorescent protein-tagged hNETs to measure substrate-transporter stoichiometry and substrate binding kinetics. Calibrated confocal microscopy and fluorescence correlation spectroscopy reveal that hNETs, which are homomultimers, bind one substrate molecule per transporter subunit. Substrate residence at the transporter, obtained from rapid on-off kinetics revealed in fluorescence correlation spectroscopy, is 526 micros. Substrate residence obtained by infinite dilution is 1000 times slower. This novel examination of substrate-transporter kinetics indicates that a single ASP+ molecule binds and unbinds thousands of times before being transported or ultimately dissociated from hNET. Calibrated fluorescent images combined with mass spectroscopy give a transport rate of 0.06 ASP+/hNET-protein/s, thus 36,000 on-off binding events (and 36 actual departures) occur for one transport event. Therefore binding has a low probability of resulting in transport. We interpret these data to mean that inefficient binding could contribute to slow transport rates.

The Forced Surrender of Infants Born to Unwed Mothers in Southern Italy. A Case Study of Late Nineteenth Century Practices in the Town of Forio d'Ischia.

For many centuries, unwed mothers in southern Italy were forced to surrender their infants because of a number of social, religious, economic, and political pressures. This study focuses on the policies and practices that were in place in southern Italy regarding illegitimate infants in the late nineteenth century. A detailed analysis of the policies and practices present in the town of Forio d'Ischia during the 20-year period 1880-1899 is also presented. During these two decades, there were 37 illegitimate live births representing 0.70% of the 5249 live births recorded in this town. Although small in number, these illegitimate births, referred to as spuri in Italian, from the Latin spurius, meaning bastard, were managed by standard predetermined procedures. These included anonymity for the parents, the transfer of such infants to an official town receiver of foundlings, and their transport to Naples' orphanage, the Real Casa Santa dell'Annunziata. This orphanage maintained fairly detailed records about the children who were delivered to it. After a few days at the orphanage, infants were often entrusted to the care of external wet nurses, preferably outside of Naples. This was done in the belief that infant survival was better assured in more rural environments. The case of an illegitimate infant, Antonino Spinalbese, is presented in detail. Born on 14 February 1882 in the town of Forio d'Ischia, he was brought to the orphanage 4 days later. Following a two-day stay at the orphanage, he was entrusted to an external wet nurse, Michele Mondella, and her husband, Ciro Fiscale di Felice, a mariner in the town of Torre del Greco. The available evidence indicates that Antonino Spinalbese became a mariner like his stepfather. As a crew member of the passenger ship, Vulcano, he made three trips from Naples to New York City in 1922 and 1923.

Migration Rate Of Tidal Meanders: Inferences From The Venice Lagoon

Meandering channels are ubiquitous features of tidal landscapes. However, despite their fundamental role on the eco-morphodynamic evolution of these landscapes, tidal meanders have received less attention when compared to their fluvial counterparts. Improving current understanding of tidal meander migration, a largely-examined topic in fluvial landscapes, is a key step to highlight analogies and differences between tidal and fluvial cases. The migration of about 400 meander bends, belonging to 40 salt-marsh channels in the Northern Venice Lagoon (Italy), from 1968 to nowadays, has been investigated by means of both a classical method in fluvial frameworks and new procedure. Similarities with fluvial meanders occur, although important difference also emerge. Meanders cutting through the San Felice marsh follow the relationship between cartesian length and channel width, typical of meanders developed within different settings. However, meander migration rates proved to be smaller than those characterizing fluvial meanders. Indeed, the analysis of meander migration suggests a mean migration rate of about 0.10 m/year, consistent with the few data available in the literature. As for the fluvial case, the maximum-potential migration rate (i.e. the envelope curve of the relationship between migration rate and bend radius, both divided by channel width) reaches a maximum for radius-over-width ratio included between 2 and 3, regardless of the considered method. Nevertheless, the new-proposed method allows us to provide a more objective and continuous characterization. By using this new procedure, the channel curvature has finally been Fourier-analyzed, confirming the importance of even harmonics along the curvature spectrum. A correlation between migration rates and dominant harmonics seems to drive the evolution of tidal meanders and might represent a key-feature to distinguish them from their fluvial counterparts.

Emergency medical practices are often team efforts. Training for various tasks and collaborations may be carried out in virtual environments. Although promising results exist from studies of serious games, little is known about the subjective reactions of learners when using multiplayer virtual world (MVW) training in medicine. The objective of this study was to reach a better understanding of the learners' reactions and experiences when using an MVW for team training of cardiopulmonary resuscitation (CPR). Twelve Swedish medical students participated in semistructured focus group discussions after CPR training in an MVW with partially preset options. The students' perceptions and feelings related to use of this educational tool were investigated. Using qualitative methodology, discussions were analyzed by a phenomenological data-driven approach. Quality measures included negotiations, back-and-forth reading, triangulation, and validation with the informants. Four categories characterizing the students' experiences could be defined: (1) Focused Mental Training, (2) Interface Diverting Focus From Training, (3) Benefits of Practicing in a Group, and (4) Easy Loss of Focus When Passive. We interpreted the results, compared them to findings of others, and propose advantages and risks of using virtual worlds for learning. Beneficial aspects of learning CPR in a virtual world were confirmed. To achieve high participant engagement and create good conditions for training, well-established procedures should be practiced. Furthermore, students should be kept in an active mode and frequent feedback should be utilized. It cannot be completely ruled out that the use of virtual training may contribute to erroneous self-beliefs that can affect later clinical performance. ©Johan Creutzfeldt, Leif Hedman, Li Felländer-Tsai.

Promoting a healthy lifestyle (eg, physical activity, healthy diet) is crucial for the primary and secondary prevention of cardiac disease in order to decrease disease burden and mortality. The current trial aims to evaluate the effectiveness of the Do Cardiac Health: Advanced New Generation Ecosystem (Do CHANGE) service, which is developed to assist cardiac patients in adopting a healthy lifestyle and improving their quality of life. Cardiac patients (ie, people who have been diagnosed with heart failure, coronary artery disease, and/or hypertension) will be recruited at three pilot sites (Badalona Serveis Assistencials, Badalona, Spain [N=75]; Buddhist Tzu Chi Dalin General Hospital, Dalin, Taiwan [N=100] and Elisabeth-TweeSteden Hospital, Tilburg, The Netherlands [N=75]). Patients will be assisted by the Do Something Different (DSD) program to change their unhealthy habits and/or lifestyle. DSD has been developed to increase behavioral flexibility and subsequently adopt new (healthier) habits. In addition, patients' progress will be monitored with a number of (newly developed) devices (eg, Fitbit, Beddit, COOKiT, FLUiT), which will be integrated in one application. The Do CHANGE trial will provide us with new insights regarding the effectiveness of the proposed intervention in different cultural settings. In addition, it will give insight into what works for whom and why. The Do CHANGE service integrates new technologies into a behavior change intervention in order to change the unhealthy lifestyles of cardiac patients. The program is expected to facilitate long-term, sustainable behavioral change.

The evolution of anatomical illustration and wax modelling in Italy from the 16th to early 19th centuries

Riva, Alessandro; Conti, Gabriele; Solinas, Paola; Loy, Francesco

2010-01-01

Although the contribution to anatomical illustration by Vesalius and his followers has received much attention, less credit has been given to Veslingius and particularly Fabricius. By 1600, Fabricius had amassed more than 300 paintings that together made the Tabulae Pictae, a great atlas of anatomy that was highly admired by his contemporaries. Many of his new observations were incorporated into subsequent books, including those by Casserius, Spighelius, Harvey and Veslingius. Also of importance were the Tabulae by Eustachius (1552), which, although only published in 1714, greatly influenced anatomical wax modelling. In 1742, Pope Benedict XIV established a Museum of Anatomy in Bologna, entrusting to Ercole Lelli the creation of several anatomical preparations in wax. Felice Fontana realised that the production of a large number of models by the casting method would make cadaveric specimens superfluous for anatomical teaching and in 1771 he asked the Grand Duke to fund a wax-modelling workshop in Florence as part of the Natural History Museum, later known as La Specola. Fontana engaged Giuseppe Ferrini as his first modeller and then the 19-year-old Clemente Susini who, by his death in 1814, had superintended the production of, or personally made, more than 2000 models. In 1780, the Austrian Emperor Joseph II visited La Specola and ordered a great number of models for his Josephinum museum; these were made by Fontana with the help of Clemente Susini and supervised by the anatomist Paolo Mascagni. It is, however, in Cagliari that some of Susini’s greatest waxes are to be found. These were made when he was free of Fontana’s influence and were based on dissections made by Francesco Antonio Boi (University of Cagliari). Their distinctive anatomical features include the emphasis given to nerves and the absence of lymphatics in the brain, a mistake made on earlier waxes. The refined technical perfection of the anatomical details demonstrates the closeness of the

The transmembrane potential is recorded from small isopotential clusters of 2-4 embryonic chick ventricular cells spontaneously generating action potentials. We analyze the cycle-to-cycle fluctuations in the time between successive action potentials (the interbeat interval or IBI). We also convert an existing model of electrical activity in the cluster, which is formulated as a Hodgkin-Huxley-like deterministic system of nonlinear ordinary differential equations describing five individual ionic currents, into a stochastic model consisting of a population of ˜20 000 independently and randomly gating ionic channels, with the randomness being set by a real physical stochastic process (radio static). This stochastic model, implemented using the Clay-DeFelice algorithm, reproduces the fluctuations seen experimentally: e.g., the coefficient of variation (standard deviation/mean) of IBI is 4.3% in the model vs. the 3.9% average value of the 17 clusters studied. The model also replicates all but one of several other quantitative measures of the experimental results, including the power spectrum and correlation integral of the voltage, as well as the histogram, Poincaré plot, serial correlation coefficients, power spectrum, detrended fluctuation analysis, approximate entropy, and sample entropy of IBI. The channel noise from one particular ionic current (IKs), which has channel kinetics that are relatively slow compared to that of the other currents, makes the major contribution to the fluctuations in IBI. Reproduction of the experimental coefficient of variation of IBI by adding a Gaussian white noise-current into the deterministic model necessitates using an unrealistically high noise-current amplitude. Indeed, a major implication of the modelling results is that, given the wide range of time-scales over which the various species of channels open and close, only a cell-specific stochastic model that is formulated taking into consideration the widely different ranges in

TOPICA: an accurate and efficient numerical tool for analysis and design of ICRF antennas

2006-07-01

The demand for a predictive tool to help in designing ion-cyclotron radio frequency (ICRF) antenna systems for today's fusion experiments has driven the development of codes such as ICANT, RANT3D, and the early development of TOPICA (TOrino Polytechnic Ion Cyclotron Antenna) code. This paper describes the substantive evolution of TOPICA formulation and implementation that presently allow it to handle the actual geometry of ICRF antennas (with curved, solid straps, a general-shape housing, Faraday screen, etc) as well as an accurate plasma description, accounting for density and temperature profiles and finite Larmor radius effects. The antenna is assumed to be housed in a recess-like enclosure. Both goals have been attained by formally separating the problem into two parts: the vacuum region around the antenna and the plasma region inside the toroidal chamber. Field continuity and boundary conditions allow formulating of a set of two coupled integral equations for the unknown equivalent (current) sources; then the equations are reduced to a linear system by a method of moments solution scheme employing 2D finite elements defined over a 3D non-planar surface triangular-cell mesh. In the vacuum region calculations are done in the spatial (configuration) domain, whereas in the plasma region a spectral (wavenumber) representation of fields and currents is adopted, thus permitting a description of the plasma by a surface impedance matrix. Owing to this approach, any plasma model can be used in principle, and at present the FELICE code has been employed. The natural outcomes of TOPICA are the induced currents on the conductors (antenna, housing, etc) and the electric field in front of the plasma, whence the antenna circuit parameters (impedance/scattering matrices), the radiated power and the fields (at locations other than the chamber aperture) are then obtained. An accurate model of the feeding coaxial lines is also included. The theoretical model and its TOPICA

The transits of Venus in 1761 and 1769 appear to mark the starting point of instrumental science in the Dutch East Indies (now Indonesia). This essay examines the conditions that triggered and constituted instrumental and institutional science on Indonesian soil in the late eighteenth century. In 1765 the Reverend J. M. Mohr, whose wife had received a large inheritance, undertook to build a fully equipped private observatory in Batavia (now Jakarta). There he made several major astronomical and meteorological observations. Mohr's initiative inspired other Europeans living on Java around 1770 to start a scientific movement. Because of the lack of governmental and other support, it was not until 1778 that this offspring of the Dutch-Indonesian Enlightenment became a reality. The Bataviaasch Genootschap van Kunsten en Wetenschappen tried from the beginning to put into effect the program Mohr had outlined. The members even bought his instruments from his widow, intending to continue his measurements. For a number of reasons, however, this instrumental program was more than the society could support. Around 1790 instrumental science in the former Dutch East Indies came to a standstill, not to be resumed for several decades.

Historical evidence of the 1936 Mojokerto skull discovery, East Java.

To resolve ambiguities in the literature, we detail the discovery history of the Mojokerto child's skull (Perning 1), employing letters, maps, photographs, reports, and newspaper accounts not previously used for this purpose. Andoyo, an experienced vertebrate-fossil collector with the Geological Survey of the Netherlands Indies, found the skull on February 13, 1936, while collecting for Johan Duyfjes, who had mapped the field area geologically. On February 18-19 Andoyo sent the fossil and a 1:25,000-topographic map showing the discovery point to Survey headquarters. The locality lies between Perning and Sumbertengu villages, approximately 10km northeast of Mojokerto city, East Java. G.H. Ralph von Koenigswald, Survey paleontologist, identified the specimen as Pithecanthropus and then named it Homo modjokertensis (it is now accepted as Homo erectus). Unfortunately he confused the discovery record in a March 28 newspaper article by characterizing the skull as a "surface find" [Dutch: oppervlaktevondst] while also attributing it to ancient beds. von Koenigswald probably had insufficient basis for either assertion, having not yet talked to Andoyo or Duyfjes. Eugene Dubois challenged von Koenigswald on the "surface-find" issue, Andoyo was consulted, and Duyfjes went to the site. Duyfjes and von Koenigswald then published scientific papers stating that the skull was unearthed 1m deep from a hill-slope outcrop of conglomeratic sandstone in Duyfjes' Pucangan formation. A cross section by Andoyo, which may show the Mojokerto site, also indicates a skull at 1m depth in conglomeratic sandstone. Photographs taken in 1936-1938 show a shallow pit at a single field location that fits Duyfjes' site description and is identified as the Mojokerto-skull site in 1940-1943 publications. By WWII the scientific community accepted the skull as an early hominid. Although von Koenigswald's "surface-find" comment remains a source of doubt in the record, we consider in situ discovery for the

In the article is presented the conception of the history of science in the interpretation of Bogdan Suchodolski. Having described the conception of the history of science created by George Sarton (1884-1956), whose thought was influenced by positivistic philosophy of August Comte, the idea of the history of science of Johan Nordstr6m (1891-1967), who was inspired by the system of Wilhelm Dilthey, and the materialistic conception of the history of science, which was represented, among others, by John Desmond Bernal (1901-1971), the author is making an attempt at revealing to what extent Bogdan Suchodolski was inspired by the above-mentioned visions of the history of science. Having defined the history of science as the history of scientific activity of people and their consciousness formed by the activity, Bogdan Suchodolski applied in the field of his own conception of the history of science the ideas that were put forward by German thinkers and philosophers, and were connected with a way of understanding culture as the constant development of national awareness, which can be exemplified with different dimensions of culture. Undoubtedly, identifying the history of Polish science with constitutive element of the history of national culture and paying attention to the conceptions tending not only to explaining, but also understanding phenomena, B. Suchodolski was influenced by Alfred Vierkandt's and Wilhelm Dilthey's thought. The present article includes several reflections on the conception of the history of science, which was created by B. Suchodolski. Among others, we can find here detailed information on how B. Suchodolski understood: the history of science, its subject, aim and methodology; its status in modern social consciousness and as the history of truth; relations between history of science and theory of science and scientific policy, history of science and the problem of unity and diversity of scientific thinking, history of science and ideas, history of

Towards a Representation of Flexible Canopy N Stiochiometry for Land-surface Models Based on Optimality Concepts

NASA Astrophysics Data System (ADS)

Zaehle, S.; Caldararu, S.

2015-12-01

Foliar nitrogen (N) is know to acclimate to environmental conditions. One particular pertinent response is the general decline in foliar N following exposure to elevated levels of atmospheric CO2 (eCO2). Associated with reduced foliar N is an increased plant nitrogen-use efficiency, which contributes to the plants' sustained growth response to eCO2 in the absence of any counteracting litter N feedbacks. Flexible leaf N thus has important consequences for the mid- to long-term response of terrestrial ecosystems to eCO2. The current generation of land-surface models including a prognostic N cycle generally employ heuristic, and simply mass-balancing parameterisations to estimate changes in stoichiometry given altered N and carbon (C) availability. This generation generally and substantially overestimates the decline of foliar N (and thus the increase in plant nitrogen use efficiency) observed in Free Air CO2 Enrichment Experiments (FACE; Zaehle et al. 2014). In this presentation, I develop a simple, prognostic and dynamic representation of flexible foliar N for use in land-surface models by maximising the marginal gain of net assimilation with respect to the energy investment to generate foliar area and foliar N. I elucidate the underlying assumptions required to simulate the commonly observed decline in foliar N with eCO2 under different scenarios of N availability (Feng et al. 2015).

MO-F-CAMPUS-J-04: Radiation Heat Load On the MR System of the Elekta Atlantic System

DOE Office of Scientific and Technical Information (OSTI.GOV)

Towe, S; Roberts, D; Overweg, J

2015-06-15

Purpose: The Elekta Atlantic system combines a digital linear accelerator system with a 1.5T Philips MRI machine.This study aimed to assess the energy deposited within the cryostat system when the radiation beam passes through the cryostat. The cryocooler on the magnet has a cooling capacity which is about 1 Watt in excess of the cryogenic heat leak into the magnet’s cold mass. A pressure-controlled heater inside the magnet balances the excess refrigeration power such that the helium pressure in the tank is kept slightly above ambient air pressure. If radiation power is deposited in the cold mass then this heatermore » will need less power to maintain pressure equilibrium and if the radiation heat load exceeds the excess cryocooler capacity the pressure will rise. Methods: An in-house CAD based Monte Carlo code based on Penelope was used to model the entire MR-Linac system to quantify the heat load on the magnet’s cold mass. These results were then compared to experimental results obtained from an Elekta Atlantic system installed in UMC-Utrecht. Results: For a field size of 25 cm x 22 cm and a dose rate of 107 mu.min-1, the energy deposited by the radiation beam led to a reduction in heater power from 1.16 to 0.73 W. Simulations predicted a reduction to 0.69 W which is in good agreement. For the worst case field size (largest) and maximum dose rate the cryostat cooler capacity was exceeded. This resulted in a pressure rise within the system but was such that continuous irradiation for over 12 hours would be required before the magnet would start blowing off helium. Conclusion: The study concluded that the Atlantic system does not have to be duty cycle restricted, even for the worst case non-clinical scenario and that there are no adverse effects on the MR system.

CryoSat-2 Processing and Model Interpretation of Greenland Ice Sheet Volume Changes

NASA Astrophysics Data System (ADS)

Nilsson, J.; Gardner, A. S.; Sandberg Sorensen, L.

2015-12-01

CryoSat-2 was launched in late 2010 tasked with monitoring the changes of the Earth's land and sea ice. It carries a novel radar altimeter allowing the satellite to monitor changes in highly complex terrain, such as smaller ice caps, glaciers and the marginal areas of the ice sheets. Here we present on the development and validation of an independent elevation retrieval processing chain and respective elevation changes based on ESA's L1B data. Overall we find large improvement in both accuracy and precision over Greenland relative to ESA's L2 product when comparing against both airborne data and crossover analysis. The seasonal component and spatial sampling of the surface elevation changes where also compared against ICESat derived changes from 2003-2009. The comparison showed good agreement between the to product on a local scale. However, a global sampling bias was detected in the seasonal signal due to the clustering of CryoSat-2 data in higher elevation areas. The retrieval processing chain presented here does not correct for changes in surface scattering conditions and appears to be insensitive to the 2012 melt event (Nilsson et al., 2015). This in contrast to the elevation changes derived from ESA's L2 elevation product, which where found to be sensitive to the effects of the melt event. The positive elevation bias created by the event introduced a discrepancy between the two products with a magnitude of roughly 90 km3/year. This difference can directly be attributed to the differences in retracking procedure pointing to the importance of the retracking of the radar waveforms for altimetric volume change studies.

Heavy Isotope Composition of Oxygen in Zircon from Soil Sample 14163: Lunar Perspective of an Early Ocean on the Earth

Thirty oxygen analyses of a large (sub-millimetre) zircon grain from the lunar soil sample 14163 have been determined using CAMECA 1270 ion microprobe. The sample 14163 was returned form the Fra Mauro region by Apollo 14 mission. Zircon grain of 0.6-0.8 mm in size extracted from the sample was imaged using CL detector fitted to the Philips Electron Microscope in order to reveal internal structure. Oxygen isotopes have been analysed during two sessions. The first set of data was collected using the original mount where the grain was set in the resin attached to the glass slide. This resulted in the two complications: (i) standard zircon has to be analysed from the separate mount and (ii) the lunar zircon grain was rased in the holder compared to the standard. In order to investigate, if the elevated oxygen compositions observed during this session could have resulted from this difference in geometric configuration during the standard and sample analyses, the lunar zircon was extracted from the original mount, remounted with the standard chip in the new resin disk and reanalysed during the second session. All analyses made during the first session show delta O-18 values heavier than 6.0%. The second set of data has a wider spread of delta O-18 values with some values as low as 5.6%. Nevertheless, a half of observed delta O-18 values in this set is also higher than 6.0%. Slightly lighter oxygen compositions observed during the second session indicate possible dependence of measured delta O-18 values on the geometry of analysed samples. Presence of zircons with similar heavy oxygen isotope compositions on the Moon, which neither had liquid water or felic crust similar to that on the Earth nor ever developed regime similar to plate tectonics, suggests that other mechanisms can be responsible for elevated delta O-18 values in zircons. This implies that there is no support for the presence of an ocean on the surface of the early Earth and as the ocean appears to be an

Pesticides end up in soil where they interact with soil microorganisms in various ways. On the Yin Side of the interaction, pesticides could exert toxicity on soil microorganisms, while on the Yang side of interaction, pesticides could be used as energy source by a fraction of the soil microbial community. The LOVE TO HATE project is an IAPP Marie Curie project which aims to study these complex interactions of pesticides with soil microorganisms and provide novel tools which will be useful both for pesticide regulatory purposes and agricultural use. On the Yin side of the interactions, a new regulatory scheme for assessing the soil microbial toxicity of pesticides will be proposed based on the use of advanced standardized tools and a well-defined experimental tiered scheme. On the Yang side of the interactions, advanced molecular tools like amplicon sequencing and functional metagenomics will be applied to define microbes that are involved in the rapid transformation of pesticides in soils and isolate novel pesticide biocatalysts. In addition, a functional microarray has been designed to estimate the biodegradation genetic potential of the microbial community of agricultural soils for a range of pesticide groups.

Post-infectious irritable bowel syndrome (PI-IBS) may develop in 4-31% of affected patients following bacterial gastroenteritis (GE), but limited information is available on long-term outcome of viral GE. During summer 2009, a massive outbreak of viral GE associated with contamination of municipal drinking water (Norovirus) occurred in San Felice del Benaco (Lake Garda, Italy). To investigate the natural history of a community outbreak of viral GE, and to assess the incidence of PI-IBS and functional gastrointestinal disorders, we carried out a prospective population-based cohort study with a control group. Baseline questionnaires were administered to the resident community within 1 month of the outbreak. Follow-up questionnaires of the Italian version of Gastrointestinal Symptom Rating Scale (GSRS, a 15-item survey scored according to a 7-point Likert scale) were mailed to all patients responding to baseline questionnaire at 3 and 6 months, and to a cohort of unaffected controls, living in the same geographical area, at 6 months after the outbreak. The GSRS item were grouped in five dimensions: abdominal pain, reflux, indigestion, diarrhea, and constipation. At month 12, all patients and controls were interviewed by a health assistant to verify Rome III criteria of IBS. Student's t-test and χ(2)- or Fisher's exact test were used as appropriate. Baseline questionnaires were returned by 348 patients: mean age ± s.d. 45 ± 22 years, 53% female. At outbreak, nausea (scored ≥4), vomiting, and diarrhea lasting 2-3 days or more were reported by 66, 60, and 77% of patients, respectively. A total of 50% reported fever and 19% reported weight loss (mean 3 kg). Follow-up surveys were returned at month 6 by 186 patients and 198 controls: mean GSRS score was significantly higher in patients than in controls for abdominal pain, diarrhea, and constipation. At month 12, we identified 40 patients with a new diagnosis of IBS (Rome III criteria), in comparison with 3 subjects in

A Investigation of the Laryngeal System as the Resonance Source of the Singer's Formant.

NASA Astrophysics Data System (ADS)

Detweiler, Rebecca Finley

Since its introduction in 1974, Johan Sundberg's model of the laryngeal system as the resonance source of the singer's formant (Fs) has gained wide acceptance. There have heretofore been no studies directly testing its validity in vivo. The purpose of this study was to undertake a direct test of that hypothesis, utilizing as subjects professional male singers trained in the western Classical tradition. The vocal behaviors of three trained singer-subjects were evaluated during modal and pulse register phonation via magnetic resonance imaging (M.R.I.), strobolaryngoscopy, and acoustical analysis. Dr. Sundberg's hypothesis rests upon two premises: (1) that the laryngeal system is acoustically isolated and therefore capable of independent resonation during artistic singing, and (2) that the laryngeal ventricle contains an air volume adequate to function as the volume element of the proposed two-tube resonating system (Sundberg, 1974). Results of the above analyses revealed that none of the subjects achieved the requisite 6:1 laryngopharynx:laryngeal outlet area ratio to support acoustic isolation and independent resonation of the laryngeal system. Further, subjects demonstrated robust and stable singer's formants in pulse register phonation concomitant to the occlusion of the laryngeal ventricular spaces as documented by M.R.I. Therefore, these data indicated that the subjects' behaviors do not fit the model of the laryngeal system as the resonance source of the singer's formant, and that the model is inadequate to account for the generation of the singer's formant in these three subjects. Further analysis of these data suggested that the singer's formant is resolvable into two component formants, termed Fs1 and Fs2. These formants are apparently analogous to F4 and F5 of speech, but are approximated by the singer to produce the desired high amplitude energy concentration. It was hypothesized that Fs1 arises from excitation of the fourth natural mode of the quarter

The Dark Side of Nature: the Crime was Almost Perfect

, watching and waiting as if for a jack-in-the-box to spring open. The MISTICI collaboration used ESO's Very Large Telescope to follow the burst for 50 days. "Despite our deep monitoring, no rebrightening due to a supernova was seen," said Gianpiero Tagliaferri from the Observatory of Brera, Italy and member of the team. "If a supernova is present, if should at least be 100 times fainter than any other supernova usually associated with a long burst." The burst exploded in a dwarf galaxy that shows moderate signs of star formation. Thus young, massive stars are present and, at the end of its life one of them could have uttered this long, agonising cry before vanishing into a black hole. "Why did it do so in a dark way, with no sign of a supernova?" asked Guido Chincarini, from the University of Milano-Bicocca, Italy, also member of the team. "A possibility is that a massive black hole formed that did not allow any matter to escape. All the material that is usually ejected in a supernova explosion would then fall back and be swallowed." ESO PR Photo 49c/06 ESO PR Photo 49b/06 GRB 060505 (FORS/VLT) The same conclusion was previously reached by another team, who monitored both GRB 060614 and another burst, GRB 060505 (5 May 2006) for 5 and 12 weeks, respectively. For this, they used the ESO VLT and the 1.54-m Danish telescope at La Silla. GRB 060505 was a faint burst with a duration of 4 seconds, and as such also belongs to the category of long bursts [1]. For GRB 060505, the astronomers could only see the burst in visible light for one night and then it faded away, while for GRB 060614, they could only follow it for four nights after the burst. Thus, if supernovae were associated with these long-bursts, as one would have expected, they must have been about a hundred times fainter than a normal supernova. "Although both bursts are long, the remarkable conclusion from our monitoring is that there were no supernovae associated with them," said Johan Fynbo from the DARK Cosmology

Scalar implicatures: experiments at the semantics-pragmatics interface.

Papafragou, Anna; Musolino, Julien

In this article we present two sets of experiments designed to investigate the acquisition of scalar implicatures. Scalar implicatures arise in examples like Some professors are famous where the speaker's use of some typically indicates that s/he had reasons not to use a more informative term, e.g. all. Some professors are famous therefore gives rise to the implicature that not all professors are famous. Recent studies on the development of pragmatics suggest that preschool children are often insensitive to such implicatures when they interpret scalar terms (Cognition 78 (2001) 165; Chierchia, G., Crain, S., Guasti, M.T., Gualmini, A., & Meroni, L. (2001). The acquisition of disjunction: evidence for a grammatical view of scalar implicatures. In A.H.-J. Do, L. Dominguez, & A.

Do, Proceedings of the 26th Boston University Conference on Language Development (pp. 406-416). Somerville, MA: Cascadilla Press). This conclusion raises two important questions: (a) are all scalar terms treated in the same way by young children?, and (b) does the child's difficulty reflect a genuine inability to derive scalar implicatures or is it due to demands imposed by the experimental task on an otherwise pragmatically savvy child? Experiment 1 addresses the first question by testing a group of 30 5-year-olds and 30 adults (all native speakers of Greek) on three different scales, (), () and (). In each case, subjects were presented with contexts which satisfied the semantic content of the stronger (i.e. more informative) terms on each scale (i.e. all, three and finish) but were described using the weaker terms of the scales (i

critical resuscitation endpoints and drug dose delivery were not improved using AR glasses. However, errors and deviations were significantly reduced in terms of defibrillation doses when compared with the use of the PALS pocket reference cards. In a total of 40 defibrillation attempts, residents not wearing AR glasses used wrong doses in 65% (26/40) of cases, including 21 shock overdoses >100 J, for a cumulative defibrillation dose of 18.7 Joules per kg. These errors were reduced by 53% (21/40, P<.001) and cumulative defibrillation dose by 37% (5.14/14, P=.001) with AR glasses.

Teaching Environmental Geochemistry as a Service-Learning Course (Invited)

NASA Astrophysics Data System (ADS)

Ku, T. C.

2010-12-01

Service-learning courses seek to broaden students’ understanding of class content through activities, which are, at the same time, of service to the community. At Wesleyan University, I have taught an Environmental Geochemistry and Laboratory course three times as a service-learning course. The course meets for two 80-minute lecture periods and one 3-hour lab period each week and class sizes have been 19-27 students. The lectures cover traditional geochemistry topics such as equilibrium thermodynamics, acid-base equilibria, oxidation-reduction reactions, and isotope geochemistry, while the lab periods focus on a semester-long environmental project in collaboration with a community organization. Problem sets and class exercises are chosen to demonstrate how theoretical concepts are applied to topics relevant to the service-learning project. The three service-learning projects and associated community partners were entitled 1) “An Initial Assessment of the North End Middletown Landfill as a Renewable Energy Sources” in collaboration with The Johan Center for Earth and Art, 2) “The Water and Sediment Geochemistry of Beseck Lake, CT: Implications for Cultural Eutrophication” in collaboration with the Beseck Lake Association, and 3) “Geochemistry and Hydrology of Jobs Pond, CT” with the Jobs Pond Water Quality Commission. Initial contact with the community partner was made through Wesleyan’s Center for Community Partnerships or through the Connecticut Department of Environmental Protection. At the start of each semester, the lead member(s) of the community organization present their environmental problem to the class. This initial meeting allows the students to hear about the problem from the community’s perspective. The faculty member collaborates with the community organization to design 5-8 mini-projects and the students are assigned group projects (2-5 students) through a ranking system. Throughout the semester each group works on their project

Geochemical variations during the 2012 Emilia seismic sequence

Several geochemical surveys (soil gas and shallow water) were performed in the Modena province (Massa Finalese, Finale Emilia, Medolla and S. Felice sul Panaro), during 2006-2014 period. In May-June 2012, a seismic sequence (main shocks of ML 5.9 and 5.8) was occurred closely to the investigated area. In this area 300 CO2 and CH4 fluxes measurements, 150 soil gas concentrations (He, H2, CO2, CH4 and C2H6), 30 shallow waters and their isotopic analyses (δ13C- CH4, δD- CH4 and δ13C- CO2) were performed in April-May 2006, October and December 2008, repeated in May and September 2012, June 2013 and July 2014 afterwards the 2012 Emilia seismic sequences. Chemical composition of soil gas are dominated by CH4 in the southern part by CO2 in the northern part. Very anomalous fluxes and concentrations are recorded in spot areas; elsewhere CO2 and CH4 values are very low, within the typical range of vegetative and of organic exhalation of the cultivated soil. After the seismic sequence the CH4 and CO2 fluxes are increased of one order of magnitude in the spotty areas, whereas in the surrounding area the values are within the background. On the contrary, CH4 concentration decrease (40%v/v in the 2012 surveys) and CO2 concentration increase until to 12.7%v/v (2013 survey). Isotopic gas analysis were carried out only on samples with anomalous values. Pre-seismic data hint a thermogenic origin of CH4 probably linked to leakage from a deep source in the Medolla area. Conversely, 2012/2013 isotopic data indicate a typical biogenic origin (i.e. microbial hydrocarbon production) of the CH4, as recognized elsewhere in the Po Plain and surroundings. The δ13C-CO2 value suggests a prevalent shallow origin of CO2 (i.e. organic and/or soil-derived) probably related to anaerobic oxidation of heavy hydrocarbons. Water samples, collected from domestic, industrial and hydrocarbons exploration wells, allowed us to recognize different families of waters. Waters are meteoric in origin and

In pursuit of empowerment: Sensei Nellie Kleinsmidt, race and gender challenges in South Africa.

Jones, D E

2001-01-01

This chapter traces the way in which Nellie Kleinsmidt, known as the grandmother of karate in Africa, has negotiated discriminatory practices and overcome race and gender-related struggles, including the struggle to free the female body, in pursuit of empowerment. It explores her expectations and the constraints and frustrations she experienced, as well as the many contributions she has made to women's karate in South Africa. Nellie Kleinsmidt's karate career, which began in 1965, coincided with the early developments of South African karate. As a woman of colour her life and karate career were significantly shaped by apartheid legislation. It divided the country into areas of occupancy and residency according to race and was designed to prevent contact between the people of the government defined race groups. Black karate-kas were prohibited by law from practising karate in white designated areas. Lack of facilities and qualified instructors in areas allocated to Kleinsmidt's race group meant that she received very little formal karate instruction between 1966 and 1973. Soon after, she met Johan Roux, a white male. He was to become her chief karate instructor and life-long companion. They defied the apartheid legislation and in 1978 set up home together. They organized defiance campaigns, resisting the pressures from government to close their dojo because of its non-racial policies. Freeing her body at the broader political level involved the abolition of the race categories and all other apartheid legislation which impacted on her life choices and experiences. Initially this struggle and that of freeing her body occurred simultaneously. In her ongoing struggle against gender discrimination in the sport, it was in karate that Nellie Kleinsmidt could strive for the personal empowerment she sought. She could however not translate this into freedom in South African society itself. The impact of apartheid legislation together with the imposition of a sports moratorium

The project is funded in part by the European Commission and takes place under the auspices of the European Science and Technology Week 2003. It is directed by the EIROforum Working Group on Outreach that brings together key members of the seven organisations' respective outreach departments. The "Physics on Stage 3" festival will be opened on Monday, November 10, by His Royal Highness, Prince Johan Friso of the Netherlands. Among the distinguished guests will also be Her Excellency, Mrs. Maria van der Hoeven, the Dutch Minister of Education, Culture and Science, as well as several Directors-General of the EIROforum organisations. This "Physics on Stage 3" festival is the most visible event within a year-long programme with the very active involvement of National Committees in two dozen European countries, each of which organised national events or competitions, during which the 400 delegates to the festival were selected for their outstanding projects to promote science teaching. Among the many entries, for example, two young physicists from Germany focus on the beauty of physical phenomena, producing fractals and demonstrating the "Theremin", the only musical instrument played without being touched. In another demonstration, a team from the UK explore the nature of sound and the theme of genetics through drama, music and physical theatre. In this third international festival of physics education, biological and biochemical themes will also play a major role. As usual, the colourful centrepiece of the week is the Fair. Every country has its own stand where delegates show their new, exciting and surprising projects, innovative software, elegant experiments, etc. In this highly inspiring atmosphere, the teachers exchange practical experience and insights, learning from each other and preparing themselves to bring back to their respective countries a rich harvest of new ideas and inspiration for better

Volcanic conduits, extensional structures, and direct contact between the volcanic rocks and the Tuscan Units, constitute the hydraulic connection between the potable fresh-water aquifer contained in the volcanites and the underlying hydrothermal system. Therefore, gaseous phases tend to flow upward (particularly through faults) carrying pollutants into the freshwater aquifer, while the freshwater recharges (also through primary permeability) the exploited geothermal fields.

Archimedes Brought to Light

Just over 100 years ago in the summer of 1906, a Danish scholar called Johan Ludvig Heiberg travelled to the famous Metochion library of the Church of the Holy Sepulcher in Constantinople. He had got wind of an intriguing medieval prayer book that had recently been found at the library, and which contained a series of Christian prayers written on parchment recycled from older books. But underneath the scrawlings of a 13th-century medieval monk, the battered manuscript also appeared to contain some strange Greek writing as well as mysterious drawings and mathematical symbols. When Heiberg saw the book, he soonmore » realized that the hidden material in fact contained the thoughts of Archimedes of Syracuse (287-212 BC) - one of the greatest thinkers of the ancient world. It was in November 2003, while on my way to a conference in Germany, that I first realized that the technique might help to uncover the hidden writings in the Archimedes Palimpsest. I had been reading an article in the German magazine GEO about the manuscript and, having previously used X-rays to detect metals in biological systems, realized that XRF could help to detect iron and other common elements in the ink. I immediately e-mailed Abigail Quandt, a conservator at the Walters Art Museum, who was part of a team that had been put in charge of the Archimedes manuscript. I was delighted to find that the team, led by her colleague William Noel, was looking for new ways to study this ancient book. Indeed, it turned out that two other researchers - Gene Hall from Rutgers University and Bob Morton from the oil firm ConocoPhillips - had also suggested using XRF imaging. Another team member - Johns Hopkins University physicist Bill Christens-Barry - had already been thinking of using X-rays too. In March 2004 Hall and the team carried out the first tests on the Palimpsest using X-rays from a commercial generator. Although these tests were promising, the results confirmed my belief that synchrotron

Planet Formation in Action? - Astronomers may have found the first object clearing its path in the natal disc surrounding a young star

Using ESO's Very Large Telescope an international team of astronomers has been able to study the short-lived disc of material around a young star that is in the early stages of making a planetary system. For the first time a smaller companion could be detected that may be the cause of the large gap found in the disc. Future observations will determine whether this companion is a planet or a brown dwarf. Planets form from the discs of material around young stars, but the transition from dust disc to planetary system is rapid and few objects are caught during this phase [1]. One such object is T Chamaeleontis (T Cha), a faint star in the small southern constellation of Chamaeleon that is comparable to the Sun, but very near the beginning of its life [2]. T Cha lies about 350 light-years from the Earth and is only about seven million years old. Up to now no forming planets have been found in these transitional discs, although planets in more mature discs have been seen before (eso0842, heic0821). "Earlier studies had shown that T Cha was an excellent target for studying how planetary systems form," notes Johan Olofsson (Max Planck Institute for Astronomy, Heidelberg, Germany), one of the lead authors of two papers in the journal Astronomy & Astrophysics that describe the new work. "But this star is quite distant and the full power of the Very Large Telescope Interferometer (VLTI) was needed to resolve very fine details and see what is going on in the dust disc." The astronomers first observed T Cha using the AMBER instrument and the VLT Interferometer (VLTI) [3]. They found that some of the disc material formed a narrow dusty ring only about 20 million kilometres from the star. Beyond this inner disc, they found a region devoid of dust with the outer part of the disc stretching out into regions beyond about 1.1 billion kilometres from the star. Nuria Huélamo (Centro de Astrobiología, ESAC, Spain), the lead author of the second paper takes up the story: "For us the

Jaunsen (formerly University of Oslo, Norway; now ESO-Paranal). [2]: Detailed reports about the early observations of this gamma-ray burst are available at the dedicated webpage within the GRB Coordinates Network website. [3]: The photometric redshift method makes it possible to judge the distance to a remote celestial object (a galaxy, a quasar, a gamma-ray burst afterglow) from its measured colours. It is based on the proportionality between the distance and the velocity along the line of sight (Hubble's law) that reflects the expansion of the Universe. The larger the distance of an object is, the larger is its velocity and, due to the Doppler effect, the spectral shift of its emission towards longer (redder) wavelengths. Thus, the measured colour provides a rough indication of the distance. Examples of this method are shown in ESO PR 20/98 (Photos 48a/00 and 48e/00). [4]: In fact, the object was so faint that the positioning of the spectrograph slit had to be done in "blind" offset, i.e. without actually seeing the object on the slit during the observation. This very difficult observational feat was possible because of excellent preparations by the team of astronomers and the very good precision of the telescope and instrument. [5]: The " Lyman-alpha forest" refers to the crowding of absorption lines from intervening hydrogen clouds, shortward of the strong Lyman-alpha spectral line at rest

important ingredient in the cosmological models is the dark matter that is believed to contribute about 95% of the mass of the universe. The present confirmation of the predictions of the models therefore also indirectly confirms that it is the dark matter that controls the formation of structures in the universe. However, there is still a long way to go before it will be possible to make a more detailed comparison between observations and predictions, e.g., from PR Photo 19e/01 to PR Photo 19a/01 ! Asked about what they consider the most important consequence of their observations, the team responds: " We have shown that we now have an observational method with which we may study the cosmic web in the early universe, and the VLT is a great tool for such studies. The way forward is now pretty clear - we just have to find those faint and distant LEGOs and then do the spectral observations from which we may determine how they are distributed in space ". More information The research described in this press release is the subject of a scientific article by the team, "Detection of a redshift 3.04 filament" , to appear as a Letter to the Editor in the European journal Astronomy & Astrophysics. Notes [1] The team consists of Palle Møller , Johan Fynbo (both at ESO, Garching) and Bjarne Thomsen (Institute of Physics and Astronomy, Aarhus, Denmark). [2] In astronomy, the redshift denotes the fraction by which the lines in the spectrum of an object are shifted towards longer wavelengths. The observed redshift of a distant hydrogen cloud or galaxy gives a direct estimate of the apparent recession velocity as caused by the universal expansion. Since the expansion rate increases with the distance, the velocity is itself a function (the Hubble relation) of the distance to the object. The higher the redshift of an object, the more distant it is and the longer is the look-back time, i.e. the earlier is the corresponding epoch.
